Ambac Financial Group, Inc. (“Ambac”), headquartered in New York City, is a holding 
company whose subsidiaries, including its principal operating subsidiaries, Ambac 
Assurance Corporation (“AAC”), Everspan Financial Guarantee Corp. and Ambac 
Assurance UK Limited (“Ambac UK”), provide financial guarantees and other financial 
services to clients in both the public and private sectors globally. AAC, including the 
Segregated Account of AAC (in rehabilitation), is a guarantor of public finance and 
structured finance obligations. Ambac’s primary goal is to maximize stockholder value 
by executing the following key strategies: active runoff of AAC and its subsidiaries 
through transaction terminations, policy commutations, settlements and restructurings 
that we believe will improve our risk profile, and maximizing the risk adjusted return 
on invested assets; loss recovery through litigation and exercise of contractual and 
legal rights; improved cost effectiveness and efficiency of the operating platform; 
rationalization of AAC’s capital and liability structures, enabling simplification of 
corporate governance and facilitating the successful rehabilitation of the Segregated 
Account; and selective business transactions offering attractive risk adjusted returns 
that, among other things, may permit utilization of Ambac’s tax net operating loss 
carry forwards. Ambac‘s common stock trades on the NASDAQ Global Select Market 
under the symbol “AMBC”. The Amended and Restated Certificate of Incorporation 
of Ambac contains substantial restrictions on the ability to transfer Ambac’s common 
stock. Subject to limited exceptions, any attempted transfer of common stock shall 
be prohibited and void to the extent that, as a result of such transfer (or any series of 
transfers of which such transfer is a part), any person or group of persons shall become 
a holder of 5% or more of Ambac’s common stock or a holder of 5% or more of Ambac’s 
common stock increases its ownership interest. Ambac is committed to providing timely 
and accurate information to the investing public, consistent with our legal and regulatory 
obligations. To that end, we use our website to convey information about our businesses, 
including the anticipated release of quarterly financial results, quarterly financial, 
statistical and business related information, and the posting of updates to the status of 
certain primary residential mortgage backed securities litigations. For more information,

Ambac Financial Group, Inc.  2016 Annual Report

“We are committed to creating  
long-term value for our shareholders.” 

CLAUDE LeBLANC  
President and Chief Executive Officer

// Dear Fellow Shareholders,

In my first letter to you since joining Ambac as President and Chief 
Executive Officer in January 2017, I want to highlight the significant 
progress the Company has made in the last few years and outline my 
plans to build on that strong momentum.

One of my first priorities in my new role has been 

•  Took action to reduce our future operating  

to actively engage in discussions with our investors, 
analysts, regulators, and several other key constituencies 
to enhance my understanding of their perspectives on 
the Company. It is clear from these discussions that this 
is an important time in Ambac’s history and I am honored 
to have the opportunity to lead the Company at such 
a critical time. While several challenges remain, I see 
substantial opportunities for Ambac to build upon its 
strong foundation to unlock and create future value  
for shareholders. 

Ambac achieved several significant key results and 

milestones in 2016:

•  Delivered solid earnings despite a challenging  
year, reporting net income of $75 million, or  
$1.64 per diluted share, and Adjusted Earnings (1)  
of $315 million, or $6.89 per diluted share

•  Finished the year with book value of $1.7  
billion, or $37.94 per share, and Adjusted  
Book Value (1) of $1.3 billion, or $29.48  
per share

•  Decreased our insured portfolio net par (2)  

by 27%, from $108 billion to $79 billion, and 
Adversely Classified Credits (2) , ( 3) (“ACCs”) by  
17% from over $20 billion down to $17 billion  

•  Negotiated and received, in early 2016, a $995 
million cash settlement with JP Morgan as part 
of our residential mortgage-backed securities 
(“RMBS”) representation and warranty litigation

costs, including annual compensation costs,  
by approximately 13%, or $7.5 million

•  Accrued an additional $28.7 million in Net 
Operating Loss (“NOL”) tolling payments  
expected to be received by Ambac Financial 
Group, Inc. (“AFG”) in May of 2017

•  Opportunistically purchased $659 million  

of Ambac-insured securities 

During 2016 we also added three highly qualified 

and experienced directors, Jim Prieur, Ian Haft and 
David Herzog, further strengthening and expanding the 
core skillset of our Board. For 2017, we made important 
modifications to management’s compensation structure, 
including increasing the equity component to further 
align management’s interests with our shareholders, 
and implementing additional objective metrics to help 
determine incentive compensation in accordance with  
our pay-for-performance philosophy. In addition, 
we adopted new compensation policies, including a 
recoupment policy and an executive stock ownership  
and retention policy. We also reduced the aggregate 
amount of director compensation while increasing the 
percentage of equity in director pay. 

Looking forward to 2017, we will be initiating a 
comprehensive review of the company’s strategy as 
well as increasing our focus on overall risk remediation 
activities to improve our company’s risk profile. As 
we strive to progress our strategic objectives, we will

CAUTIONARY  STATEMENT  PURSUANT  TO  THE 
PRIVATE SECURITIES LITIGATION REFORM ACT OF 
1995 

In  this Annual  Report,  we  have  included  statements  that  may 
constitute “forward-looking statements” within the meaning of the 
safe harbor provisions of the Private Securities Litigation Reform 
Act  of  1995.  Words  such  as  “estimate,”  “project,”  “plan,” 
“believe,”  “anticipate,”  “intend,”  “planned,”  “potential”  and 
similar expressions, or future or conditional verbs such as “will,” 
“should,” “would,” “could,” and “may,” or the negative of those 
expressions  or  verbs,  identify  forward-looking  statements.  We 
caution readers that these statements are not guarantees of future 
performance. Forward-looking statements are not historical facts 
but  instead  represent  only  our  beliefs  regarding  future  events, 
which, may by their nature be inherently uncertain and some of 
which may be outside our control. These statements may relate to 
plans and objectives with respect to the future, among other things 
which may change. We are alerting you to the possibility that our 
actual results may differ, possibly materially, from the expected 
objectives or anticipated results that may be suggested, expressed 
or implied by these forward-looking statements. Important factors 
that could cause our results to differ, possibly materially, from those 
indicated in the forward-looking statements include, among others, 
those  discussed  under  “Risk  Factors”  in  Part  I,  Item 1A  of  this 
Annual Report on Form 10-K. 

Any or all of management’s forward-looking statements here or in 
other publications may turn out to be incorrect and are based on 
management’s current belief or opinions. Ambac’s actual results 
may  vary  materially,  and  there  are  no  guarantees  about  the 
performance  of  Ambac’s  securities.  Among  events,  risks, 
uncertainties  or  factors  that  could  cause  actual  results  to  differ 
materially  are:  (1) the  highly  speculative  nature  of  Ambac’s 
common  stock  and  volatility  in  the  price  of Ambac’s  common 
stock; (2) uncertainty concerning our ability to achieve value for 
holders  of  Ambac  securities,  whether  from  Ambac  Assurance 
Corporation  (“Ambac  Assurance”)  or  from  transactions  or 
opportunities apart from Ambac Assurance; (3) adverse effects on 
our share price resulting from future offerings of debt or equity 
securities that rank senior to our common stock; (4) potential of 
rehabilitation proceedings against Ambac Assurance; (5) dilution 
of current shareholder value or adverse effects on our share price 
resulting from the issuance of additional shares of common stock; 
(6) inadequacy of reserves established for losses and loss expenses 
and possibility that changes in loss reserves may result in further 
volatility of earnings; (7) decisions made by the rehabilitator of 
the  Segregated Account  of Ambac Assurance  Corporation  (the 
“Segregated Account”) for the benefit of policyholders that may 
result in material adverse consequences for holders of Ambac’s 
securities  or  holders  of  securities  issued  or  insured  by Ambac 
Assurance or the Segregated Account; (8) increased fiscal stress 
experienced by issuers of public finance obligations or an increased 
incidence of Chapter 9 filings or other restructuring proceedings 
by public finance issuers; (9) our inability to realize the expected 
recoveries  included  in  our  financial  statements;  (10) credit  risk 
throughout our business, including but not limited to credit risk 
related to residential mortgage-backed securities, student loan and 
other asset securitizations, collateralized loan obligations, public 
finance obligations and exposures to reinsurers; (11) the risk that 
our  risk  management  policies  and  practices  do  not  anticipate 
certain risks and/or the magnitude of potential for loss; (12) risks 
associated with adverse selection as our insured portfolio runs off;

PART I

Item 1.  Business

INTRODUCTION

Ambac  Financial  Group,  Inc.  (“Ambac”  or  the  “Company”), 
headquartered in New York City, is a financial services holding 
company incorporated in the State of Delaware on April 29, 1991.   
On  May 1,  2013, Ambac  emerged  from  Chapter  11  bankruptcy 
protection  when  the  Second  Modified  Fifth Amended  Plan  of 
Reorganization became effective.  Upon emergence Ambac had 
no outstanding debt at the holding company and approximately $5 
billion of net operating loss carry-forwards, of which $4.0 billion 
remain at December 31, 2016. 

Ambac’s  primary  goal  is  to  maximize  stockholder  value  by 
executing the following key strategies: 

•  Active  runoff  of Ambac Assurance  and  its  subsidiaries 
through  transaction  terminations,  policy  commutations, 
settlements and restructurings that we believe will improve 
our risk profile, and maximizing the risk-adjusted return 
on invested assets;  

• 

• 

• 

• 

Loss recovery through litigation and exercise of contractual 
and legal rights;  

Improved cost effectiveness and efficiency of the operating 
platform;  

Rationalization of Ambac's and its subsidiaries' capital and 
liability  structures,  enabling  simplification  of  corporate 
governance and facilitating the successful rehabilitation of 
the Segregated Account; and 

Selective  business  transactions  offering  attractive  risk-
adjusted  returns  that,  among  other  things,  may  permit 
utilization of Ambac’s net operating loss carry-forwards. 

In March 2010, Ambac Assurance established a segregated account 
to  Wisconsin  Stat.  §611.24(2)  (the  “Segregated 
pursuant 
Account”) to segregate certain segments of Ambac Assurance’s 
liabilities. The Office of the Commissioner of Insurance for the 
State of Wisconsin (“OCI” (which term shall be understood to refer 
to such office as regulator of Ambac Assurance and to refer to the 
Commissioner  of  Insurance  for  the  State  of  Wisconsin  as 
rehabilitator of the Segregated Account (the “Rehabilitator”), as 
the  context  requires))  commenced  rehabilitation  proceedings  in 
the Wisconsin Circuit Court for Dane County (the “Rehabilitation 
Court”) with respect to the Segregated Account (the “Segregated 
Account Rehabilitation Proceedings”) in order to permit OCI to 
facilitate  an  orderly  run-off  and/or  settlement  of  the  liabilities 
allocated to the Segregated Account pursuant to the provisions of 
the Wisconsin Insurers Rehabilitation and Liquidation Act.  Ambac 
Assurance is not, itself, in rehabilitation proceedings. 

On  October 8,  2010,  OCI  filed  a  plan  of  rehabilitation  for  the 
Segregated  Account  (the  “Segregated  Account  Rehabilitation 
Plan”)  in  the  Rehabilitation  Court.  The  Rehabilitation  Court 
confirmed  the  Segregated  Account  Rehabilitation  Plan  on 
January 24,  2011.  On  June  11,  2014,  the  Rehabilitation  Court 
approved amendments to the Segregated Account Rehabilitation 
Plan and the Segregated Account Rehabilitation Plan, as amended, 
became effective on June 12, 2014. Following the effective date 

of the Segregated Account Rehabilitation Plan, as amended, the 
interim payment percentage (“IPP”) for permitted policy claims 
increased from 25% to 45% with effect from July 21, 2014. As 
with previously permitted policy claims, the remaining portion of 
the unpaid permitted policy claims (in this case, 55%) will remain 
outstanding as Deferred Amounts (as defined in the Segregated 
Account Rehabilitation Plan) and, subject to the adjustment for 
Undercollateralized Bonds (as defined in the Segregated Account 
Rehabilitation Plan), will accrue interest at 5.1% per annum. These 
Deferred Amounts,  together  with  interest  thereon,  may  be  paid 
from  time  to  time  in  the  future  at  the  sole  discretion  of  the 
Rehabilitator. 

Ambac Assurance is evaluating the possibility of entering into one 
or more transactions to improve the financial condition of Ambac 
Assurance  which  may,  subject  to  OCI  approval,  lead  to  the 
conclusion of the Segregated Account Rehabilitation Proceedings.  
In  pursuing  this  objective, Ambac Assurance  is  considering  the 
possibility  of  monetizing  certain  assets,  restructuring  or 
exchanging  certain  outstanding  debt  and  insurance  obligations, 
and/or  commuting  or  reducing  insured  exposures.    Ambac 
Assurance  is  also  discussing  with  OCI  potential  options  for 
addressing outstanding Segregated Account and other obligations.  
From  time  to  time  Ambac  Assurance  has  also  discussed,  and 
intends  to  continue  discussing,  with  counterparty  creditors  and 
OCI a potential transaction pursuant to which outstanding Deferred 
Amounts and surplus notes, in each case including accrued interest, 
would  be  exchanged  for  or  satisfied  by  indebtedness,  or  other 
instruments which may include securities, and cash or other assets. 
In  evaluating  potential  transactions,  we  understand  that  OCI 
intends  to  consider,  among  other  things,  their  impact  on  the 
company  and  policyholders,  and  we  intend  to  consider,  among 
other things, their impact on the company and our stakeholders, 
including, in each case, their legal, regulatory and tax implications.  

However, Ambac Assurance has not reached any agreement on the 
terms of any such transaction, and we cannot provide any assurance 
that  any  such  transaction  will  be  consummated  by  Ambac 
Assurance  in  the  future,  or  if  it  is,  as  to  the  timing,  terms  or 
conditions of any such transaction, or as to whether it could lead 
to  the  conclusion  of  the  Segregated  Account  Rehabilitation 
Proceedings.  Any such transaction proposed by Ambac Assurance 
would be subject to the prior approval of the board of directors of 
Ambac Assurance,  OCI  and  the  Rehabilitation  Court  and  may 
require third-party consents, which may not be obtained.  OCI has 
not indicated a course of action to address Segregated Account or 
other  obligations  or  to  conclude  the  Segregated  Account 
Rehabilitation  Proceedings.    As  stated  in  the  Supplement  (as 
defined below), the goal of the SDC (as defined below) is to provide 
additional  directional  guidance  regarding  the  status  of  the 
Segregated Account rehabilitation during the first quarter of 2017, 
barring  any  unforeseen  developments  that  might  impede  that 
effort. The terms, conditions, and timing of a potential conclusion 
of the Segregated Account Rehabilitation Proceedings are in the 
sole  discretion  of  OCI,  and  subject  to  the  approval  of  the 
Rehabilitation  Court.    This  discretion  includes  the  authority  to 
address Segregated Account obligations without the agreement of 
Ambac Assurance or its board of directors.  Moreover, even if the 
Segregated Account Rehabilitation Proceedings could be brought 
to a successful conclusion, there can be no assurance that any level 
of capital deemed sufficient by OCI to permit such conclusion will 
be  sufficient  to  cover  all  future  losses,  whether  currently 
anticipated or unanticipated.

On July 12, 2016, the Special Deputy Commissioner ("SDC") for 
the Segregated Account met with policy beneficiaries and holders 
of surplus notes of Ambac Assurance and the Segregated Account 
during which the SDC stated (i) that at present, the Rehabilitator 
does not have any plans to increase the interim payment percentage 
(“IPP”) on Segregated Account policy claims, commenting that 
the  Rehabilitator  and  his  advisors  would  need  to  feel  highly 
confident that any change to the IPP would be sustainable and fair 
to all policyholders; (ii) that the Rehabilitator reserves the right to 
amend the Segregated Account Rehabilitation Plan or take such 
other action as he deems necessary or appropriate to adjust the rate 
of accretion on Deferred Amounts from time to time based on such 
factors  as  he  considers  relevant  and,  as  such,  the  accretion  rate 
remains under review; and (iii) his objective of seeking an exit of 
the Segregated Account from rehabilitation, and further stated that 
although  his  preferred  goal  would  be  to  achieve  an  exit  from 
rehabilitation  through  a  consensual  plan,  he  would  advise  the 
Rehabilitator to use all tools available to accomplish a successful 
and  durable  conclusion  that  enhances Ambac Assurance's  long-
term claims-paying ability.

that 

the  Supplement, 

On  December  16,  2016,  the  Rehabilitator  filed  with  the 
Rehabilitation Court a supplement to his 2016 Annual Report dated 
June  1,  2016  relating  to  the  Segregated Account  Rehabilitation 
Proceedings  (the  “Supplement”).  In 
the 
Rehabilitator  reiterated  his  goal  of  achieving  a  successful  and 
durable  conclusion  to  the  Segregated  Account  Rehabilitation 
Proceedings. The Rehabilitator also stated in the Supplement that 
at  the  present  time and absent  further  actions,  Ambac Assurance 
has  insufficient  capital  to  demonstrate to the satisfaction of the 
the  Segregated  Account  Rehabilitation 
Rehabilitator 
Proceedings could be concluded  and leave Ambac Assurance with 
sufficient financial resources to  meet  all policy  obligations,  as  
projected  by  the  Rehabilitator  (in  his  sole  discretion)  under  
a    varying    range    of    base    and    stress    case    scenarios.     The 
Rehabilitator  further  stated  in  the  Supplement  that  given  such 
requirements,  any transaction facilitating the conclusion of the 
Segregated Account  Rehabilitation  Proceedings  will    need    to  
provide  for  an  increase  in  Ambac Assurance’s  existing  surplus  
capital, as determined and defined by OCI in its sole discretion. 
We  cannot  provide  assurance  that  the  terms  of  any  possible 
transaction  will  satisfy  OCI  or  the  Rehabilitator  that  Ambac 
Assurance has, or will have, sufficient capital to meet all policy 
obligations  after  the  conclusion  of  the  Segregated  Account 
Rehabilitation Proceedings.

The  execution  of Ambac’s  strategy  to  actively  run  off Ambac 
Assurance  and  its  subsidiaries  is  subject  to  the  authority  of  the 
Rehabilitator  to  control  the  management  of  the  Segregated 
Account. In exercising such authority, the Rehabilitator will act 
for the benefit of policyholders, and will not take into account the 
interests of Ambac.  The Rehabilitator's authority includes, but is 
not limited to, sole discretion over the rate at which the Segregated 
Account pays claims and the accretion rate on Deferred Amounts.  
Similarly,  by  operation  of  the  contracts  executed  in  connection 
with  the  establishment,  and  subsequent  rehabilitation,  of  the 
Segregated Account, the Rehabilitator retains rights to oversee and 
approve certain actions taken by or in respect of Ambac Assurance.  
Accordingly, oversight by the Rehabilitator could impair Ambac’s 
ability  to  execute  certain  of  its  strategies.  Opportunities  for 
transaction  terminations,  policy  commutations,  settlements  and 
restructurings  also  depend  on  market  conditions,  including  the 
perception of Ambac Assurance’s creditworthiness, the structure 

of  the  underlying  risk  and  associated  policy  as  well  as  other 
counterparty  specific  factors.    Ambac  Assurance's  ability  to 
commute  policies  or  purchase  certain  investments  may  also  be 
limited by available liquidity.

Refer  to  Note  1.  Background  and  Business  Description  to  the 
Consolidated Financial Statements included in Part II, Item 8 in 
this Form 10-K, for more information on the Segregated Account 
and the Segregated Account Rehabilitation Proceedings.

Although  we  are  exploring  selective  business  transactions  for 
Ambac, no assurance can be given that we will be able to execute 
the acquisition or development of any new businesses or assets.  
In addition, there can be no assurance that we will be able to obtain 
the financial and other resources that may be required to finance 
the acquisition or development of new businesses or assets that 
may  permit  utilization  of  Ambac’s  net  operating  loss  carry-
forwards. Due to these factors, as well as uncertainties relating to 
the  ability  of Ambac Assurance  to  deliver  value  to Ambac,  the 
value of our securities is highly speculative.  

Ambac has two reportable business segments: Financial Guarantee 
and Financial Services. 

Ambac’s  Financial  Guarantee  business  segment  is  conducted 
through its primary operating subsidiary, Ambac Assurance and its 
wholly owned subsidiary Ambac Assurance UK Limited (“Ambac 
UK”), both of which have been in runoff since 2008. Insurance 
policies insured by Ambac Assurance and Ambac UK generally 
guarantee payment when due of the principal and interest on the 
obligations  guaranteed.  Ambac  Assurance  also  has  another 
wholly-owned financial guarantee subsidiary, Everspan Financial 
Guarantee Corp. (“Everspan”), which has been in runoff since its 
acquisition in 1997. The deterioration of the financial condition of 
Ambac Assurance and Ambac UK has prevented these companies 
from being able to write new business.  An inability to write new 
business has and will continue to negatively impact Ambac’s future 
operations and financial results. Ambac Assurance’s ability to pay 
dividends  and,  as  a  result,  Ambac’s  liquidity,  have  been 
significantly restricted by the deterioration of Ambac Assurance’s 
financial condition, by the rehabilitation of the Segregated Account 
and by the terms of the Settlement Agreement, dated as of June 7, 
2010  (the  "Settlement  Agreement"),  by  and  among  Ambac 
Assurance, Ambac  Credit  Products  LLC  (“ACP”), Ambac  and 
certain counterparties to credit default swaps with ACP that were 
guaranteed  by  Ambac  Assurance.  Ambac  Assurance  is  also 
restricted in its ability to pay dividends pursuant to the terms of its 
Auction Market Preferred Shares. It is highly unlikely that Ambac 
Assurance will be able to make dividend payments to Ambac for 
the foreseeable future. Refer to "Dividend Restrictions, Including 
Contractual Restrictions" below and Note 8. Insurance Regulatory 
Restrictions to the Consolidated Financial Statements included in 
Part II, Item 8 in this Form 10-K, for more information on dividend 
payment restrictions. 

Ambac Assurance  and its subsidiaries have been working toward 
reducing uncertainties within its insured portfolio through active 
monitoring and management of key exposures such as Puerto Rico, 
asset-backed  securities  (including  residential  mortgage-backed 
(RMBS) and student loans) and municipal entities with stressed 
financial  conditions.    Additionally,  Ambac  Assurance  and  its 
subsidiaries  are  actively  prosecuting  legal  claims  (including 
RMBS related lawsuits), managing the regulatory framework and 

| Ambac Financial Group, Inc.   3   2016 FORM 10-K |

other  aspects  of  the  Segregated  Account,  seeking  to  optimize 
capital allocation in a challenging environment that includes long 
duration obligations and attempting to retain key employees.

Ambac’s  Financial  Services  business  segment  is  operated  by 
subsidiaries of Ambac Assurance.  This segment provides financial 
and  investment  products,  including  investment  agreements, 
funding conduits and interest rate swaps, principally to the clients 
of its financial guarantee business. The Financial Services business 
also  maintains  interest  rate  derivatives  to  mitigate  exposure  to 
floating  rate  insured  obligations  in  the  Financial  Guarantee 
segment. Ambac Assurance  insured  all  of  the  obligations  of  its 
financial services subsidiaries. The financial services businesses 
are  in  runoff,  which  is  being  effectuated  by  transaction 
terminations, 
scheduled 
amortization of contracts.

Enterprise Risk Management

The Company's policies and procedures relating to risk assessment 
and risk management are overseen by its Board of Directors. The 
Board  takes  an  enterprise-wide  approach  to  risk  management 
oversight that is designed to support the Company's business plans 
at a reasonable level of risk. A fundamental part of risk assessment 
and  risk  management  is  not  only  understanding  the  risks  the 
Company faces and what steps management is taking to manage 
those risks, but also understanding what level of risk is appropriate 
for  the  Company. The  Board  of  Directors  annually  reviews  the 
Company's business plan, factoring risk management into account. 
It  also  approves  the  Company's  risk  appetite  statement,  which 
articulates  the  Company's  tolerance  for  risk  and  describes  the 
general types of risk that the Company accepts or attempts to avoid. 

While  the  Board  of  Directors  has  the  ultimate  oversight 
responsibility  for 
the  risk  management  process,  various 
committees of the Board also have responsibilities related to risk 
assessment  and  risk  management,  and  management  has 
responsibility  for  managing  the  risks  to  which  the  Company  is 
exposed and reporting on such matters to the Board of Directors 
and applicable Board committees.

The Audit Committee oversees the management of risks associated 
with  the  integrity  of  Ambac’s  financial  statements  and  its 
compliance with legal and regulatory requirements. In addition, 
the  Audit  Committee  discusses  policies  with  respect  to  risk 
assessment and risk management, including major financial risk 
exposures  and  the  steps  management  has  taken  to  monitor  and 
control  such  exposures.  The  Audit  Committee  reviews  with 
management,  internal  auditors,  and  external  auditors  Ambac's 
accounting policies, our system of internal controls over financial 
reporting, and the quality and appropriateness of disclosure and 
content  in  the  financial  statements  and  other  external  financial 
communications.

The Compensation Committee oversees the management of risk 
primarily associated with our ability to attract, motivate and retain 
quality 
talent,  compensation 
structures that might lead to undue risk taking, and disclosure of 
our executive compensation philosophies, strategies and activities.

management of risk primarily associated with Ambac’s ability to 
attract and retain quality directors, Ambac’s corporate governance 
therewith. 
programs  and  practices  and  our  compliance 

Additionally, 
the  Governance  and  Nominating  Committee 
oversees the processes for evaluation of  the performance of the 
Board, its committees and management each year and considers 
risk  management  effectiveness  as  part  of  their  evaluation.  The 
Governance and Nominating Committee also performs oversight 
of  the  business  ethics  and  compliance  program,  and  reviews 
compliance with Ambac’s Code of Business Conduct.

The Strategy and Risk Policy Committee oversees the management 
of risk and risk appetite primarily with respect to strategic plans 
and initiatives, oversight of Ambac’s capital structure, financing 
and treasury matters and oversight of management's process for 
the identification, evaluation and mitigation of Ambac’s financial 
and commercial-related risks.

The  full  Board  also  receives  quarterly  updates  from  Board 
committees,  and  the  Board  provides  guidance  to  individual 
committee activities as appropriate.

In order to assist the board of directors in overseeing Ambac’s risk 
management,  Ambac  uses  enterprise  risk  management,  a 
company-wide  initiative  that  involves  the  Board  of  Directors, 
management and other personnel in an integrated effort to identify, 
assess and manage risks that may affect the Company’s ability to 
execute on its corporate strategy and fulfill its business objectives.  
These  activities  entail  the  identification,  prioritization  and 
assessment of a broad range of risks (e.g., credit, financial, legal, 
liquidity, market, model, operational, regulatory and strategic), and 
the formulation of plans to manage these risks or mitigate their 
effects.

The  Enterprise  Risk  Committee  (“ERC”)  is  a  management 
committee  which  is  comprised  of  senior  level  management 
responsible for assisting in the management of the Company’s risks 
on  an  individual  and  aggregate  basis.  The  ERC  produces  the 
relevant risk management information for senior management, the 
Board of Directors and applicable Board committees. 

Common Stock Restrictions

Ambac’s Amended and Restated Certificate of Incorporation limits 
voting  and  transfer  rights  of  stockholders  in  significant  ways. 
Article  IV  contains  voting  restrictions  applicable  to  any  person 
owning at least 10% of Ambac’s common stock so that such person 
(including  any  group  consisting  of  such  person  and  any  other 
person with whom such person or any affiliate or associate of such 
person has any agreement, contract, arrangement or understanding 
with respect to acquiring, voting, holding or disposing of Ambac’s 
common stock) shall not be entitled to cast votes in excess of one 
vote less than 10% of the votes entitled to be cast by all common 
stock holders, except as otherwise approved by OCI.

There are substantial restrictions on the ability to transfer Ambac’s 
common stock set forth in Article XII of Ambac’s Amended and 
Restated Certificate of Incorporation. In order to preserve certain 
tax benefits, subject to limited exceptions, any attempted transfer 
of common stock shall be prohibited and void to the extent that, 
as a result of such transfer (or any series of transfers of which such 
transfer is a part), either (i) any person or group of persons shall 
become a holder of 5% or more of the Company’s common stock 
or (ii) the percentage stock ownership interest in Ambac of any 
holder of 5% or more of the Company’s common stock shall be 
increased  (a  “Prohibited Transfer”). These  restrictions  shall  not 
apply to an attempted transfer if the transferor or the transferee 

| Ambac Financial Group, Inc.   4   2016 FORM 10-K |

obtains the written approval of Ambac’s Board of Directors to such 
transfer. A purported transferee of a Prohibited Transfer shall not 
be  recognized  as  a  stockholder  of  Ambac  for  any  purpose 
whatsoever in respect of the securities which are the subject of the 
Prohibited  Transfer  (the  “Excess  Securities”).  Until  the  Excess 
Securities are acquired by another person in a transfer that is not 
a  Prohibited  Transfer,  the  purported  transferee  of  a  Prohibited 
Transfer shall not be entitled with respect to such Excess Securities 
to  any  rights  of  stockholders  of  Ambac,  including,  without 
limitation, the right to vote such Excess Securities and to receive 
dividends  or  distributions,  whether  liquidating  or  otherwise,  in 
respect  thereof,  if  any.  Once  the  Excess  Securities  have  been 
acquired in a transfer that is not a Prohibited Transfer, the securities 
shall cease to be Excess Securities. If the Board determines that a 
transfer of securities constitutes a Prohibited Transfer then, upon 
written demand by Ambac, the purported transferee shall transfer 
or  cause  to  be  transferred  any  certificate  or  other  evidence  of 
ownership  of  the  Excess  Securities  within  the  purported 
transferee’s possession or control, together with any distributions 
paid by Ambac with respect to such Excess Securities, to an agent 
designated by Ambac. Such agent shall thereafter sell such Excess 
Securities and the proceeds of such sale shall be distributed as set 
forth in the Amended and Restated Certificate of Incorporation. If 
the  purported  transferee  of  a  Prohibited Transfer  has  resold  the 
Excess Securities before receiving such demand, such person shall 
be deemed to have sold the Excess Securities to Ambac’s agent 
and shall be required to transfer to such agent the proceeds of such 
sale, which shall be distributed as set forth in the Amended and 
Restated Certificate of Incorporation.

FINANCIAL GUARANTEE SEGMENT

The Financial Guarantee segment includes insurance policies and 
credit derivative contracts provided by Ambac Assurance and its 
subsidiaries.  Generally, 
financial  guarantees  provide  an 
unconditional and irrevocable guarantee which protects the holder 
of a debt obligation against non-payment when due. Pursuant to 
such  guarantees,  Ambac  Assurance  and  its  subsidiaries  make 

payments if the obligor responsible for making payments fails to 
do  so  when  scheduled.  Credit  derivatives  also  permit  certain 
counterparties to assert mark-to-market termination claims under 
certain conditions; however, the assertion of such mark-to-market 
claims  has  been  enjoined  by  the  Rehabilitation  Court.  See 
discussion  of  “Ambac Assurance  Liquidity”  in  Part  II,  Item 7 
included in this Form 10-K for further information. 

Ambac’s  financial  guarantee  insurance  policies  and  credit 
derivative contracts expose the Company to the direct credit risk 
of the assets and/or obligor supporting the guaranteed obligation. 
In addition,  insured transactions expose Ambac to indirect risks 
that may increase our overall risk, such as credit risk separate from, 
but correlated with, our direct credit risk, market, model, economic, 
natural disaster and mortality or other non-credit type risks. 

Ambac  Assurance  derives  financial  guarantee  revenues  from: 
(i) premiums earned from insurance contracts, net of reinsurance; 
(ii) net  investment  income;  (iii) fees  from  credit  derivative 
transactions;  (iv) net  realized  gains  and  losses  from  sales  of 
investment  securities;  and  (v) amendment  and  consent  fees. 
Financial guarantee expenses include: (i) loss and commutation 
payments  for  credit  exposures;  (ii) loss-related  expenses, 
including those relating to the remediation of problem credits; (ii) 
insurance  intangible  amortization  and  (iv) operating  expenses. 
Premiums for financial guarantees were received either upfront or 
on  an  installment  basis  from  the  cash  flows  generated  by  the 
underlying  assets  (typical  of  structured  finance  obligations). 
Despite not underwriting new business, Ambac continues to collect 
premiums on its existing portfolio of guarantees that pay premiums 
on  an  installment  basis.  See  “Management’s  Discussion  and 
Analysis  of  Financial  Condition  and  Results  of  Operations” 
included  in  Part  II,  Item 7  in  this  Form  10-K  for  further 
information. 

Risk Management 

The  Asset  Liability  Management  Committee  (“ALCO”)  is  a 
management committee with the objective to implement and foster 
an enterprise wide culture and approach to liquidity management, 
asset valuation, hedging, and risk remediation. Members of ALCO 
include the Chief Executive Officer, Chief Financial Officer and 
senior  managers  from  investment  management,  capital  markets 
and the Risk Management Group. ALCO has scheduled monthly 
meetings and will also meet on an ad hoc basis to consider, for 
example,  the  commutation  of  distressed  financial  guarantee 
exposures.  

The  Risk  Management  group  is  primarily  responsible  for  the 
development,  implementation  and  oversight  of  loss  mitigation 
strategies, surveillance and remediation of the insured financial 
guarantee portfolio (including through the pursuit of recoveries in 
respect  of  paid  claims  and  commutations  of  policies).  As  a 
consequence  of 
the  Segregated  Account  Rehabilitation 
Proceedings,  the  Rehabilitator  retains  operational  control  and 
decision-making authority with respect to all matters related to the 
Segregated Account, including surveillance, remediation and loss 
mitigation.  The  Rehabilitator  operates  the  Segregated Account 
through a management services contract executed between Ambac 
Assurance and the Segregated Account pursuant to which the Risk 
Management  group  and  other  personnel  provide  surveillance, 
remediation  and  loss  mitigation  services  to  the  Segregated 
Account.  Furthermore, by virtue of the contracts executed between 
Ambac Assurance and the Segregated Account, the Rehabilitator 

| Ambac Financial Group, Inc.   5   2016 FORM 10-K |

retains the discretion to oversee and approve certain actions taken 
by Ambac Assurance in respect of assets and liabilities that have 
not  been  allocated  to  the  Segregated Account.  Refer  to  Note  1. 
Background  and  Business  Description  to  the  Consolidated 
Financial Statements included in Part II, Item 8 in this Form 10-
K,  for  more  information  on  the  contracts  between  Ambac 
Assurance  and  the  Segregated Account. As  such,  the  following 
discussion of Ambac’s risk management practices is qualified by 
reference to the Rehabilitator’s exercise of any of its rights to alter 
or eliminate any of these risk management practices. 

Ambac’s Risk Management group has an organizational structure 
designed  around  three  primary  areas  of  focus:  Portfolio  Risk 
Management  and Analysis,  Credit  Risk  Management  and  Loss 
Reserving and  Analytics.   The senior manager responsible for 
these  groups reports directly to Ambac's Chief Executive Officer 
and regularly informs and updates the Audit Committees of the 
Board of Directors of Ambac and Ambac Assurance with respect 
to risk-related topics in the insured portfolio.

Portfolio Risk Management and Analysis ("PRM")

This  group’s  focus  is  on  remediation,  loss  mitigation,  risk 
reduction,  restructuring  and  surveillance.  Proactive  credit 
remediation can help to reduce exposure and/or reduce risk in the 
insured portfolio by securing rights and remedies, both of which 
help  to  mitigate  losses  in  the  event  of  default.  Restructuring  or 
workout is the focused and active process of minimizing claims 
and maximizing  recoveries typically following an event of default. 
The emphasis on reducing risk is centered on reducing enterprise-
wide exposure on a prioritized basis. 

PRM  personnel  perform  periodic  surveillance  reviews  of 
exposures according to a schedule based on the risk profile of the 
guaranteed obligations or as necessitated by specific credit events 
or  other  macro-economic  variables.  Risk-adjusted  surveillance 
strategies have been developed for each bond type with review 
periods  and  scope  of  review  based  upon  each  bond  type’s  risk 
profile. The risk profile is assessed regularly in response to our 
own  experience  and  judgments  or  external  factors  such  as  the 
economic environment and industry trends. Monitoring activities 
are designed to detect deterioration in credit quality or changes in 
the  economic,  regulatory  or  political  environment  which  could 
adversely impact the portfolio. Active surveillance enables PRM 
to track single credit migration and industry credit and performance 
trends.  The  focus  of  the  surveillance  review  is  to  assess 
performance,  identify  credit  trends  and  recommend  appropriate 
credit classifications, ratings and changes to a transaction or bond 
type’s review period and surveillance requirements. If a problem 
is detected, the group focuses on loss mitigation by recommending 
appropriate  action  and  working  with  the  issuer,  trustee,  bond 
counsel,  servicer  and  other  interested  parties  in  an  attempt  to 
remediate the problem and minimize Ambac Assurance’s exposure 
to potential loss. Those credits that are either in default or have 
developed problems that eventually may lead to a default or claim 
payment are tracked closely by the appropriate surveillance team 
and senior risk managers as part of the restructuring or workout 
process and discussed at regularly scheduled meetings with Credit 
Risk  Management  (see  discussion  following  in  “Credit  Risk 
Management”).  In some cases, PRM will engage restructuring or 
workout  experts,    attorneys  and  /  or  other  consultants  with 
appropriate expertise in the targeted loss mitigation area to assist 
management in examining the underlying contracts or collateral, 
providing industry specific advice and/or executing strategies.

In  structured  transactions,  including  structured  public  finance 
transactions, Ambac Assurance often is the control party as a result 
of insuring the transaction’s senior class or tranche. The control 
party may direct specified parties, usually the trustee, to take or 
not take certain actions following contractual defaults or trigger 
events. Control rights and the scope of direction and remedies vary 
considerably  among  our  insured  transactions.  Because  Ambac 
Assurance  is  party  to  and/or  has  certain  rights  in  documents 
supporting transactions in the insured portfolio, Ambac Assurance 
frequently  receives  requests  for  amendments,  waivers  and 
consents  (“AWCs”).  As  discussed  below  under  “Credit  Risk 
Management,” Ambac Assurance’s  risk  management  personnel 
review, analyze and process all requests for AWCs. As a part of 
the  Segregated  Account  Rehabilitation  Proceedings, 
the 
Rehabilitation Court enjoined certain actions by other parties to 
preserve Ambac Assurance’s control rights that could otherwise 
have lapsed or been compromised. 

Surveillance for collateral dependent transactions, including, but 
not limited to, residential mortgage-backed securities (“RMBS”), 
asset-backed  securities  (“ABS”)  and  student  loan  transactions, 
focuses  on  review  of  the  underlying  asset  cash  flows  and,  if 
applicable, the performance of servicers or collateral managers. 
Ambac  Assurance  generally  receives  periodic  reporting  of 
transaction  performance  from  issuers  or  trustees.  Risk  analysts 
review these reports to monitor performance and, if necessary, seek 
legal or accounting advice to ensure that reporting and application 
of cash flows comply with transaction requirements. 

Cross-functional  teams  have  been  established,  across  PRM  and 
other groups as necessary given the targeted strategy to promote 
active mitigation and remediation of losses associated with certain 
credits and sectors in the insured portfolio. Examples of such teams 
include  teams  of  professionals  focused  on  (i) the  review  and 
enforcement  of  contractual  representations  and  warranties  in 
RMBS  policies,  (ii) RMBS  servicing  and  (iii) the  analysis  and 
prioritization of policies with projected claims to target and execute 
risk reduction and commutation strategies. The establishment and 
purview of cross-functional teams is targeted to address our highest 
risk exposures. Members of such teams work with both internal 
and external experts in the pursuit of risk reduction on all fronts. 

The  RMBS  servicing  team  focuses  on  servicer  oversight  and 
remediation.  Analysts  monitor  the  performance  of  servicers 
through  a  combination  of  (i) regular  reviews  of  servicer 
performance; (ii) compliance certificates received from servicer 
management;  (iii) independent  rating  agency  information;  (iv)  
reviews of servicer financial information; and (v) onsite servicing 
diligence. Servicer performance reviews typically include a review 
including  comparisons  against 
of  collateral  performance, 
benchmarks,  as  well  as  the  processes  of  collection,  default 
management, and loss mitigation. Ambac Assurance may require 
a  back-up  servicer  or  require  “term-to-term”  servicing  which 
provides for limited, renewable servicing terms in order to provide 
greater  flexibility  regarding  the  servicing  arrangements  of  a 
particular transaction. 

In some transactions, Ambac Assurance has the right to direct a 
transfer of RMBS and other servicing to an alternative servicer, 
upon certain events and subject to certain conditions. The decision 
to exercise this right is made based on various factors, including 
an  assessment  of  the  performance  of  the  existing  servicer  as 
outlined  above,  and  an  assessment  of  whether  a  transfer  of 

| Ambac Financial Group, Inc.   6   2016 FORM 10-K |

servicing  may  improve  the  performance  of  the  collateral  and 
reduce risk to Ambac Assurance.  In the case of RMBS, Ambac 
Assurance has developed relationships with preferred servicers. 
Preferred  servicers  are  selected  through  a  formalized  servicer 
review  process  that  determines,  among  other  key  factors,  the 
servicer’s ability and willingness to actively manage intense and 
proven loss mitigation activities on RMBS. Ambac Assurance may 
decide to exercise its rights to direct the transfer of servicing to a 
preferred servicer where such rights are available. The transfer of 
servicing is done with the objectives of (i) minimizing losses and 
distress levels by deploying targeted and enhanced loss mitigation 
programs;  (ii) increasing  visibility  to  Ambac  Assurance  of  all 
servicing  activities  that  impact  overall  deal  performance; 
(iii) better  aligning  the  servicer’s  financial  interest  to  the 
performance  of  the  underlying  deal  through  the  utilization  of 
performance based incentives; and (iv) reducing the risk of servicer 
underperformance due to servicer financial difficulty.

Ambac  Assurance  believes  that  the  improved  loss  mitigation 
activities, alignment of interests and close monitoring of servicers 
constitute credible means of minimizing risks and losses related 
to insured RMBS. 

A team of professionals is focused on recoveries from sponsors 
where  Ambac  Assurance  believes  material  breaches  of 
representations  and  warranties  have  occurred  with  respect  to 
certain  RMBS  policies.   The  team  engages  with  experienced 
consultants  to  perform  the  re-underwriting  of  loan  files  and 
consults with internal and external legal counsel with regard to 
loan putbacks as well as settlement and litigation strategies (refer 
to  Note  7.  Financial  Guarantee  Insurance  Contracts  to  the 
Consolidated Financial Statements included in Part II, Item 8 in 
this Form 10-K for further discussion on this topic). 

PRM focuses on the analysis, implementation and execution of 
commutation and related claims reduction or defeasance strategies 
for policies with projected claims. Analysts evaluate the estimated 
timing and severity of such projected policy claims as well as the 
potential impact of other loss mitigation strategies in order to target 
and prioritize policies, or portions thereof, for commutation, bond 
purchase,  refinancing  or  other  claims  reduction  or  defeasance 
strategies.  For  targeted  policies,  analysts  will  engage  with 
bondholders, issuers and other economic stakeholders to negotiate, 
structure, and execute such strategies. 

Credit Risk Management ("CRM")

CRM manages the decision process for all material matters that 
affect credit exposures within the insured portfolio. While PRM is 
responsible for the credit analysis and the recommendation and 
execution of credit remediation strategies, CRM provides a forum 
for independent assessments and approvals and drives consistency 
and timeliness. Strategic level credit and restructuring issues may 
also involve the CEO and other executive management to augment 
the CRM process in the interest of achieving best outcomes. The 
scope  of  credit  matters  under  the  purview  of  CRM  includes 
material amendments, waivers and consents, remediation plans, 
credit review scheduling, adverse credit classification and below 
investment grade rating designations, adversely classified credit 
reviews, sector reviews and overall portfolio review. The CRM 
decision process may involve a review of structural, legal, political 
and credit issues and also includes determining the proper level of 
approval, which varies based on the nature and materiality of the 
matter.  Decisions  that  also  have  material  asset,  liability,  and 

liquidity implications, such as commutations, bond purchases and 
refinancings may also require ALCO approval. Please refer to Note 
2. Basis of Presentation and Significant Accounting Policies to the 
Consolidated Financial Statements included in Part II, Item 8 in 
this  Form  10-K  for  further  discussion  of  the  various  credit 
classifications. 

Adversely Classified Credit Review 

Credits that are either in default or have developed problems that 
eventually  may  lead  to  a  default  are  tracked  closely  by  the 
appropriate PRM surveillance team and discussed at meetings with 
CRM. Adversely classified credit meetings include members of 
CRM, PRM and legal, as necessary. As part of the review, relevant 
information,  along  with  the  plan  for  corrective  actions  and  a 
reassessment  of  the  credit’s  rating  and  credit  classification  is 
considered. Internal and/or external counsel generally review the 
documents underlying any problem credit and, if applicable, an 
analysis  is  prepared  outlining  Ambac  Assurance’s  rights  and 
potential  remedies,  the  duties  of  all  parties  involved  and 
recommendations  for  corrective  actions. Ambac Assurance  also 
meets  with  relevant  parties  to  the  transaction  as  necessary. The 
review schedule for adversely classified credits is tailored to the 
remediation  plan  to  track  and  prompt  timely  action  and  proper 
internal  and  external  resourcing. A  summary  of  developments 
regarding  adversely  classified  credits  and  credit  trends  is  also 
provided to Ambac’s and Ambac Assurance’s Board of Directors 
no less than quarterly.

The insured portfolio contains exposures that are correlated and/
or concentrated. Ambac’s surveillance includes identifying these 
types of exposures and identifying the risks that would or could 
trigger credit deterioration across the related exposures. When such 
risks occur, adverse credit classification may be warranted across 
many of the correlated and/or concentrated exposures. This is the 
case  with  student  loans  and  RMBS,  for  example,  which  have 
several  correlations  including  those  associated  with  consumer 
lending, unemployment and home prices. In the past, our not-for-
profit healthcare and our leveraged lease exposures experienced 
periods of stress arising from their concentrated and/or correlated 
risks, when there were major changes to healthcare reimbursement 
programs  especially  Medicaid,  or  significant  weakness  in 
consumer and business travel, in the case of the former and the 
latter, respectively. In the future, Ambac’s portfolio may be subject 
to  similar  credit  deterioration  arising  from  concentrated  and/or 
correlated risks. Examples of other such risks that could impact 
our  portfolio,  and  that  our  surveillance  is  designed  to  monitor 
include the impact of potential municipal bankruptcy contagion or 
the impact of large scale domestic military cutbacks on our military 
housing portfolio or event risk such as natural disasters or other 
regional stresses. Most such risks cannot be predicted, and may 
materialize  unexpectedly  or  develop  rapidly.  Although  our 
surveillance allows us to connect the event and stress to the related 
exposures and assign an adverse credit classification and estimate 
losses across the affected credits, when necessary, we may not have 
adequate resources or contractual rights and remedies to mitigate 
loss arising from such risks. 

Amendment, Waiver and Consent Review / Approval 

The decision to approve or reject AWCs is based upon certain credit 
factors, such as the issuer’s ability to repay the bonds and the bond’s 
security features and structure. Members of Ambac Assurance’s 
PRM group review, analyze and process all requests for AWCs. 

| Ambac Financial Group, Inc.   7   2016 FORM 10-K |

All AWCs are initially screened for materiality in the surveillance 
groups. Non-material AWCs require the approval of at least a PRM 
surveillance analyst and a portfolio risk manager. Material AWCs 
are  within  the  purview  of  CRM,  as  noted  above.  For  material 
AWCs, CRM has established minimum requirements that may be 
modified to require more or varied approvals depending upon the 
matter’s complexity, size or other characteristics. 

Ambac  Assurance  assigns  internal  credit  ratings  to  individual 
exposures as part of the AWC process and at surveillance reviews. 
These internal credit ratings, which represent Ambac Assurance’s 
independent  judgments,  are  based  upon  underlying  credit 
parameters consistent with the exposure type. 

Loss Reserving and Analytics Group ("LRA")

LRA  manages  the  quarterly  loss  reserving  process  for  insured 
portfolio credits with projected policy claims. It also supports the 
development, operation and/or  maintenance of various analytical 
models used in the loss reserving process as well as in other risk 
management  functions.    LRA  will  work  together  with  PRM 
analysts  responsible  for  a  particular  credit  on  the  development, 
review and implementation of loss reserve scenarios and related 
analysis.

Financial Guarantees in Force 

Financial guarantee products were sold in three principal markets: 
U.S.  public  finance,  U.S.  structured  finance  and  international 
finance. The following table provides a breakdown of guaranteed 
net par outstanding by market sector at December 31, 2016 and 
2015.  Net par exposures within the U.S. public finance market 
include capital appreciation bonds which are reported at the par 
amount at the time of issuance of the insurance policy.  Guaranteed 
net par outstanding includes the exposures of policies that insure 
variable  interest  entities  (“VIEs”)  consolidated  by  Ambac. 
Guaranteed net par outstanding excludes the exposures of policies 
that insure bonds which have been refunded or pre-refunded:

that  were  executed  in  the  form  of  credit  derivatives,  primarily 
collateralized loan exposures. See Part II, Item 7, “Management’s 
Discussion  and Analysis  of  Financial  Condition  and  Results  of 
Operations” and Item 8, “Financial Statements and Supplementary 
Data” for further discussion of credit derivative exposures. 

Certain  guaranteed  bonds  were  issued  as  floating  rate  debt, 
including  Auction  Rate  Securities  and  Variable  Rate  Demand 
Obligations,  which  may  introduce  interest  rate  risk  to  Ambac 
Assurance.  Refer  to Auction  Rate  Securities  and  Variable  Rate 
Demand Obligation Exposures below for further discussion. 

U.S. Public Finance Insured Portfolio 

Ambac’s  portfolio  of  U.S.  public  finance  exposures  is  $45,062 
million, representing 57% of Ambac’s net par outstanding as of 
December 31,  2016  and  a  31%  reduction  from  the  amount 
outstanding at December 31, 2015. This reduction in exposure was 

mainly  due  to  normal  exposure  runoff  in  addition  to  early 
terminations  (calls,  refundings  and  pre-refundings).  While 
Ambac’s U.S. public finance portfolio consists predominantly of 
municipal bonds such as general and revenue obligations and lease 
and tax-backed obligations of state and local government entities, 
the portfolio also comprises a wide array of non-municipal types 
of  bonds,  including  financings  for  not-for-profit  entities  and 
transactions  with  public  and  private  elements,  which  generally 
finance infrastructure, housing and other public interests.  See Note 
6. Financial Guarantees in Force to the Consolidated Financial 
Statements,  included  in  Part  II,  Item 8  in  this  Form  10-K  for 
exposures by bond type. 

Municipal bonds are generally supported directly or indirectly by 
the  issuer’s  taxing  authority  or  by  public  sector  fees  and 
assessments which may or may not be specifically pledged. Risk 
factors  in  these  transactions  derive  from  the  municipal  issuer, 
including its fiscal management, politics, and economic position, 
as well as its ability and willingness to continue to pay its debt 
service. Municipal bankruptcies, while still relatively uncommon, 
have occurred, exposing Ambac to the risk of liquidity claims and 
ultimate losses if issuers cannot successfully adjust their liabilities 
without impairing creditors. 

Not-for-profit transactions are generally supported by the not-for-
profit entities’ net revenues and may also include specific pledges, 
liens and/or mortgages. The entity typically serves a well-defined 
market  and  promulgates  a  public  purpose  mission.  These 
transactions  may  afford Ambac  contractual  protections  such  as 
financial  covenants  and  control  rights  in  the  event  of  issuer 
breaches  and  defaults.  Risk  factors  in  these  transactions  derive 
from the creditworthiness of the issuer, including but not limited 
to, its financial condition, leverage, management, business mix, 
competitive  position, 
trends, 
government programs, etc. Examples of these types of transactions 
include  not-for-profit  hospitals,  universities,  associations  and 
charities.

industry  and  socioeconomic 

Public/private transactions are generally structured to achieve their 
targeted public interest objective without direct support from the 
public  sector.  Some  examples  of  this  type  of  financing  include 
affordable housing, private education, and privatized military and 
student housing. Protections within these financings provided to 
Ambac  usually  include  the  strength  of  the  financed  asset’s 
essentiality  and  public  purpose  and  may  include  financial 
covenants,  collateral  and  control  rights.  Risk  factors  include 
financial underperformance, event risk and a shift in the asset’s 
mission or essentiality. One example of this type of financing is 
U.S. military housing. Ambac insures approximately $5.9 billion 
net par of privatized military housing debt. The debt was issued to 
finance  the  construction  and/or  renovation  of  housing  units  for 
military  personnel  and  their  families  on  domestic  U.S.  military 
bases. Debt service is not directly paid or guaranteed by the U.S. 
Government. Rather, the bonds are serviced from the cash flow 
generated  in  most  cases  by  rental  payments  deposited  by  the 
military  directly  into  lockbox  accounts  as  part  of  each  service 
personnel’s Basic Allowance for Housing (BAH). In small number  
of cases rental payments are also coming from civilians, including 
retired service personnel, living on a particular base. Collateral for 
these transactions includes the BAH payments as well as an interest 
in  the  ground  lease. Risk  factors  affecting  these  transactions 
include the ongoing base essentiality, military deployments, the 
the 
U.S.  government’s  commitment

Puerto Rico

Ambac has exposure to Puerto Rico across several different issuing 
entities.  Each has its own credit risk profile attributable to discrete 
revenue  sources,  direct  general  obligation  pledges  and  general 
obligation guarantees. The following table shows Ambac's insured 
exposure to each issuer segregated by whether such debt obligation 
is subject to the Priority Debt Provision or "clawback."  Ambac 
has  initiated  litigation  challenging  the  application  of  the 
"clawback" announced by Governor Padilla, Puerto Rico's former  

Most  Puerto  Rico  bonds  insured  by Ambac Assurance  are  not 
subject 
to  acceleration.  The  Ambac-insured  Puerto  Rico 
Convention  Center  District  Authority  (Hotel  Occupancy  Tax) 
bonds  may  be  accelerated  only  with  the  consent  of,  or  at  the 
direction of, Ambac Assurance. The Ambac-insured Puerto Rico 
Sales  Tax  Financing  Corporation's  Senior  Sales  Tax  Revenue 
bonds  may  be  accelerated  only  with  the  consent  of  Ambac 
Assurance,  subject  to  the Ambac  financial  guaranty  insurance 
policy being in full force and effect.

Internal credit ratings are provided solely to indicate the underlying credit quality of guaranteed obligations based on the view of Ambac Assurance. In 
cases where Ambac Assurance has insured multiple tranches of an issue with varying internal ratings, or more than one obligation of an issuer with varying 
internal ratings, a weighted average rating is used. Ambac Assurance credit ratings are subject to revision at any time and do not constitute investment 
advice. Ambac Assurance, or one of its affiliates, has guaranteed the obligations listed and may also provide other products or services to the issuers of 
these obligations for which Ambac Assurance may have received premiums or fees. “BIG” denotes credits deemed below investment grade. 

(2)    Net Par includes capital appreciation bonds, which are reported at the par amount at the time of issuance of the insurance policy.  Accretion of the capital 

appreciation bonds would increase the related net par by $616 million at December 31, 2016.

(3)  Net par and interest outstanding ("P&I") represents the total insured future debt service remaining over the lifetime of the bonds.  P&I for capital appreciation

to 

implement 

In November and December 2015, former Governor Padilla issued 
certain  executive  orders  purporting 
the 
Commonwealth Constitution’s Priority Debt Provision for Fiscal 
Year 2016, due to his claim that there are insufficient revenues to 
pay all appropriations for the year.  The executive orders called for 
the "clawback" of certain revenues that would otherwise have been 
transferred  to  the  Puerto  Rico  Highways  and  Transportation 
Authority  (“HTA”),  the  Puerto  Rico  Infrastructure  Financing 
Authority  (“PRIFA”)  and  the  Puerto  Rico  Convention  Center 
District  Authority  (“PRCCDA”)  to  be  transferred  instead  for 
application to the Commonwealth’s public debt.  As a result, such 

revenues  were  not  available  to  pay  debt  service  owed  by  those 
entities, including on bonds insured by Ambac Assurance.  Ambac 
has filed a lawsuit in U.S. District Court, District of Puerto Rico, 
asserting  that  the  executive  orders  and  diversion  of  revenues 
violate the U.S. Constitution.  Refer to Note 17. Commitments and 
Contingencies to the Consolidated Financial Statements included 
in Part II, Item 8 in this Form 10-K for a further discussion of this 
lawsuit.

In June 2016, the United States enacted the Puerto Rico Oversight, 
Management,  and  Economic  Stability  Act  (“PROMESA”). 
Among other things, PROMESA provides for a temporary stay on 

| Ambac Financial Group, Inc.   9   2016 FORM 10-K |

litigation  concerning 

the  debt  obligations  of 

certain 
the 
Commonwealth and its instrumentalities. The federal district court 
overseeing various creditor lawsuits in the District of Puerto Rico 
has held that the PROMESA litigation stay applies broadly, and 
the U.S. Court of Appeals for the First Circuit has affirmed the 
district court's denial of one plaintiff's attempt to lift the litigation 
stay.  These rulings may limit Ambac Assurance's ability to engage 
in certain aspects of loss mitigation in the short term. The litigation 
stay, which was originally set to expire on February 15, 2017, has 
been extended until May 1, 2017.

On October 28, 2016, Ambac Assurance opted not to contest the 
application  of  the  PROMESA  litigation  stay  to  its  lawsuit 
challenging  the  "clawback"  orders,  while  reserving  the  right  to 
seek to lift the stay in the future.  As a result, there may be additional 
delay in obtaining a ruling on the merits of the claims asserted in 
this lawsuit.

Since  April  2016,  the  Commonwealth  has  been  subject  to  an 
emergency moratorium, known as "Law 21," on debt payments of 
the Commonwealth and its instrumentalities. Beginning in April 
2016, and culminating on June 30, 2016, former Governor Padilla 
issued additional executive orders under Law 21 declaring states 
of emergency at HTA, PRIFA, PRCCDA, and other Puerto Rico 
instrumentalities  through  January  31,  2017,  and  suspending 
payment obligations on bonds issued by those entities, including 
bonds 
the 
insured  by  Ambac  Assurance.  Subsequent 
implementation of the moratorium, the Commonwealth defaulted 
on approximately $0.9 billion out of $2.0 billion of debt service 
due on July 1, 2016, including certain Puerto Rico bonds insured 
by Ambac Assurance.  On  January  29,  2017,  current  Governor 
Rosello signed the Financial Emergency and Fiscal Responsibility 
Act, which extends the emergency moratorium period until May 
1, 2017, with an option to extend another three months until August 
1, 2017. 

to 

PROMESA provides that laws such as Law 21 are not binding on 
any non-consenting creditor to the extent they prohibit the payment 
of principal or interest.  The practical effect of this provision is 
unknown and therefore Ambac is at risk to the ongoing execution, 
interpretation  and  ultimate  enforcement  of  this  provision.  
PROMESA  also  provides  that  unlawful  executive  orders  are 
preempted  under  PROMESA,  but  there  is  no  procedure  for 
determining  whether  a  particular  executive  order  is  unlawful, 
creating uncertainty in general and with specific regards to how 
the preemption provision will be implemented towards Ambac’s 
exposures.

On October 7, 2016, certain holders of Puerto Rico’s GO bonds 
requested leave of court to file an amended complaint that, among 
other things, challenges the structure of the Puerto Rico Sales Tax 
Financing Corporations ("COFINA") and seeks injunctive relief 
requiring the sales and use tax proceeds securing the bonds issued 
by COFINA to be transferred to the Commonwealth treasury for 
payment of GO bonds.  On October 26, 2016, Ambac filed a motion 
to intervene in that lawsuit and argued that the proposed claims 
are subject to PROMESA’s litigation stay.  The Court granted the 
GO plaintiffs’ motion to file an amended complaint on November 
4, 2016.  On February 17, 2017, the Court issued an opinion and 
order  granting  Ambac’s  motion  to  intervene  and  denying  the 

request to stay the litigation under PROMESA. The Court clarified 
that claims asserted under PROMESA, which could not have been 
commenced before the enactment of the statute, are not subject to 
the  litigation  stay.    If  successful,  the  GO  plaintiffs’  challenge 
against COFINA, and any similar claims that could be asserted by 
other  plaintiffs  in  the  future,  could  have  a  significant  negative 
impact on Ambac’s liquidity, loss reserves and capital resources.

As  noted  above,  PROMESA  creates  a  new  federal  legislative 
framework for Puerto Rico.  It is untested and many provisions are 
unique.  There is inherent uncertainty and risk both generally and 
for Ambac’s  exposures  specifically  regarding  the  interpretation 
and  implementation  of  PROMESA.   Among  other  things, 
PROMESA contains provisions that may permit consensual and 
non-consensual  restructurings  of  debt  obligations  of 
the 
Commonwealth and its instrumentalities.  PROMESA also confers 
significant  powers  and  responsibilities  on  the  oversight  board 
created thereunder (the “Oversight Board”).  Among other things, 
the Oversight Board is required to certify any insolvency petitions 
that may be filed by Puerto Rico instrumentalities under Title III 
of  PROMESA,  any  proposed  plans  of  adjustment  in  such 
proceedings,  and  any  voluntary  restructuring  agreement  among 
creditors under Title VI of PROMESA (which has the potential to 
bind  non-consenting  creditors).    The  Oversight  Board  is  also 
required  to  approve  fiscal  plans  and  budgets  submitted  by  the 
Commonwealth  and  monitor  compliance  with  those  plans  and 
budgets, and to approve any debt issuances or modifications by 
the Commonwealth or its instrumentalities.  Ambac is unable to 
predict  to  what  extent  debt  restructurings  will  be  proposed  or 
implemented under PROMESA, and how its insured obligations 
will fare in any such restructurings.   

On  October  14,  2016,  former  Governor  Padilla  presented  the 
Commonwealth’s Fiscal and Economic Growth Plan (“FEGP”) to 
PROMESA oversight board members.  The FEGP lays out various 
economic scenarios in which Puerto Rico incurs significant deficits 
over the next 10 years.  These range from $58.7 billion, if Puerto 
Rico  loses  Affordable  Care  Act  money  from  the  federal 
government in 2018 and other revenue shortfall assumptions, to 
$5.7 billion, if Puerto Rico excludes all debt service payments over 
the  next  10  years  in  isolation.   These  scenarios  implied  that 
significant cuts to debt service obligations are required in order to 
balance budgets and eliminate fiscal deficits.  The Oversight Board 
did not certify this FEGP prior to end of Governor Padilla's term 
in December 2016.

Current Governor Rosello has agreed to provide a proposed FEGP 
to the Oversight Board by February 28, 2017. The Oversight Board 
expects that the FEGP will be certified by March 31, 2017. The 
Oversight Board has requested that the proposed FEGP includes, 
among other things, $3 billion  in cuts to healthcare, University of 
Puerto  Rico  and  pensions,  and  $1.5  billion 
in  revenue 
enhancements by Fiscal Year 2019. It is currently unclear what, if 
anything, the proposed FEGP will do to address the restructuring 
of debt obligations of the Commonwealth or its instrumentalities.  
However, any such restructuring proposal may include material 
cuts to payment of principal and interest on debts insured by Ambac 
Assurance.

advice. Ambac Assurance, or one of its affiliates, has guaranteed the obligations listed and may also provide other products or services to the issuers of 
these obligations for which Ambac Assurance may have received premiums or fees. “BIG” denotes credits deemed below investment grade.

U.S. Structured Finance Portfolio 

Ambac’s portfolio of U.S. structured finance exposures is $16,951 
million, representing 21% of Ambac’s net par outstanding as of 
December 31,  2016  and  a  22%  reduction  from  the  amount 
outstanding at December 31, 2015. This reduction in exposure was 
the result of normal exposure runoff, primarily related to residential 
mortgage-backed  policies,  in  addition  to  terminations  and 
commutations of student loan and asset backed policies. Insured 
exposures include securitizations of mortgage loans, home equity 
loans, student loans, leases, operating assets, collateralized debt 
obligations ("CDO"), collateralized loan obligations (“CLO”), and 
other asset-backed financings, in each case where the majority of 
the  underlying  collateral  risk  is  situated  in  the  United  States. 
Included within the lease securitization sector are pooled aircraft 
and railcar transactions.  Additionally, Ambac’s structured finance 
insured portfolio includes secured and unsecured debt issued by 
investor-owned  utilities,    structured  insurance  transactions  and 
aircraft  equipment  trust  certificates.  See  Note  6.  Financial 
Guarantees  in  Force  to  the  Consolidated  Financial  Statements, 
included  in  Part  II,  Item 8  included  in  this  Form  10-K,  for 
exposures by bond type as of December 31, 2016. 

Structured finance exposures generally entail three forms of risk: 
(i) asset  risk,  which  relates  to  the  amount  and  quality  of  the 
underlying assets; (ii) structural risk, which relates to the extent to 
which the transaction’s legal structure and credit support provide 
protection from loss; and (iii) servicer risk, which is the risk that 
poor performance at the servicer or manager level contributes to 

a  decline  in  cash  flow  available  to  the  transaction.  Ambac 
Assurance seeks to mitigate and manage these risks through its 
risk management practices. 

Structured  securities  are  usually  designed  to  help  protect  the 
investors  and,  therefore,  the  guarantor  from  the  bankruptcy  or 
insolvency of the entity that originated the underlying assets as 
well as from the bankruptcy or insolvency of the servicer of those 
assets.  The  servicer  of  the  assets  is  typically  responsible  for 
collecting cash payments on the underlying assets and forwarding 
such payments, net of servicing fees, to a trustee for the benefit of 
the issuer. One potential issue is whether the sale of the assets by 
the originator to the issuer would be upheld in the event of the 
bankruptcy or insolvency of the originator and whether the servicer 
of the assets may be permitted or stayed from remitting to investors 
cash collections held by it or received by it after the servicer or the 
originator  becomes  subject 
insolvency 
proceedings. Another potential issue is whether the originator sold 
ineligible assets to the securitization transaction that subsequently 
deteriorated, and, if so, whether the originator has the willingness 
or  financial  wherewithal  to  meet  its  contractual  obligations  to 
repurchase those assets out of the transaction. Structural protection 
in a transaction, such as control rights that are typically held by 
the senior note holders, or guarantor in insured transactions, will 
determine the extent to which underlying asset performance can 
be  influenced  upon  non-performance  to  improve  the  revenues 
available to cover debt service.

risk management. 

Ambac UK, which is regulated in the United Kingdom (“UK”), 
had been Ambac Assurance’s primary vehicle for directly issuing 
financial guarantee policies in the UK and the European Union 
with  $15,082  million  net  par  outstanding  in  those  markets  at 
insured  exposures 
December 31,  2016.  The  portfolio  of 
underwritten by Ambac UK is financially supported exclusively 
by the assets of Ambac UK and no capital support arrangements 
are in place with any other Ambac affiliate. 

International Finance Insured Portfolio 

Ambac’s  portfolio  of  international  finance  insured  exposures  is 
$17,333 million, representing 22% of Ambac’s net par outstanding 
as of December 31, 2016 and an 18% reduction from the amount 
outstanding at December 31, 2015. This reduction in exposure was 
primarily the result of the strengthening of the US dollar, exposure 
runoff including reduction of certain aircraft leasing obligations 
and  other  policy  terminations.    Ambac’s  international  finance 
insured  exposures  include  a  wide  array  of  obligations  in  the 
international markets, including infrastructure financings, asset-
securitizations,  utility  obligations,  and  whole  business 
securitizations  (e.g.  securitizations  of  substantially  all  of  the 
operating assets of a corporation). Ambac no longer has insured 
exposure  related  to  emerging  markets.    See  Note  6.  Financial 
Guarantees  in  Force  to  the  Consolidated  Financial  Statements, 
included  in  Part  II,  Item 8  included  in  this  Form  10-K,  for 
exposures by bond type as of December 31, 2016.

risks include the legal and political environment, capital markets

Other European Union Exposures (“EU”)

Ambac's international exposures are principally in the United Kingdom; however, we also have exposures with credit risk based in various 
other EU member states, including Austria, France, Germany, Italy and Spain.  Several of these countries have experienced significant economic, 
fiscal and/or political strains such that the likelihood of default on such obligations is higher than when the policies were underwritten.  The 
Company’s exposures, net of reinsurance, to these countries are shown in the following table:

Ambac does not guarantee any sovereign bonds of the above EU 
countries.  However, the exposures classified as sub sovereign may 
be impacted should there be adverse financial developments in the 
EU. Those exposures classified as infrastructure/operating asset 
backed  are  concession  based  where  the  underlying  assets 
independently generate cash flow without operational reliance on 
the  sovereign.  Of  the  below  investment  grade  exposures,  the 
investor-owned utilities (wind farm and mini hydro-electric plant) 
are undergoing restructuring processes designed to address their 
performance issues. The other below investment grade exposure 
is  a  road  transaction,  where  performance  has  been  poorer  than 
anticipated due to lower than forecast traffic volumes, however 
performance is improving.  Below investment grade is defined as 
those exposures with a credit rating below BBB-.

Brexit:

In  a  non-binding  referendum  on  the  United  Kingdom’s  (“UK”) 
membership  in  the  European  Union  ("EU")  in  June  2016,  a 
majority of those who voted approved the UK’s withdrawal from 
the EU. Withdrawal by the UK from the EU (“Brexit”) would occur 
after,  or  possibly  concurrently  with,  a  process  of  negotiation 
regarding the future terms of the UK’s relationship with the EU, 
which could result in the UK losing access to certain aspects of 
the single EU market and the global trade deals negotiated by the 
EU on behalf of its members. The Brexit vote and the perceptions 
as to the impact of the withdrawal of the UK may adversely affect 
business activity, political stability and economic conditions in the 
UK, the Eurozone, the EU and elsewhere. The economic outlook 
could be further adversely affected by (i) the risk that one or more 
other EU countries could come under increasing pressure to leave 
the  EU,  (ii)  the  risk  of  a  greater  demand  for  independence  by 
Scottish nationalists or for unification in Ireland, or (iii) the risk 

that the Euro as the single currency of the Eurozone could cease 
to exist. Any of these developments, or the perception that any of 
these  developments  are  likely  to  occur,  could  have  a  material 
adverse effect on economic growth or business activity in the UK, 
the Eurozone, and the EU, and could result in the relocation of 
businesses,  cause  business  interruptions,  lead  to  economic 
recession or depression, and impact the stability of the financial 
markets, the availability of credit, political systems or financial 
institutions and the financial and monetary system.  Consequently 
the  medium  and  longer  term  impact  on  the  UK  generally,  and 
Ambac UK specifically, is uncertain. 

The vote caused volatility in global stock markets and currency 
exchange rate fluctuations that resulted in the strengthening of the 
U.S.  dollar  against  foreign  currencies,  particularly  the  British 
Pound and to a lesser extent the Euro.  Ambac's wholly-owned UK 
subsidiary, Ambac UK, operates in the United Kingdom and the 
British Pound is its functional currency.  Ambac UK conducts a 
portion  of  its  business  in  currencies  other  than  its  functional 
currency,  predominately  the  Euro  and  US  Dollar.  Refer  to 
"Executive Summary - Foreign Currency Impacts" included in  Part 
II, Item 7 in this Form 10-K, for more information on the economic 
and financial statement impact of such changes to foreign currency 
exchange rates. 

Since the referendum vote, there has been a reduction in net par 
outstanding of insured exposures denominated in British Pounds 
and Euro of $2,678 million, primarily due to the strengthening of 
the  US  dollar.    As  of  December 31,  2016  insured  exposures 
denominated  in  British  Pounds  totaled  £10,136  million  and  in 
Euros €1,831 million.

Additional Insured Portfolio Information 

Average Life of Insured Portfolio 

Ambac underwrote and priced financial guarantees based on the 
assumption  that  the  guarantees  would  remain  in  force  until  the 
maturity of the underlying bonds. Ambac estimates that the average 
life  of  its  guarantees  on  par  in  force  at  December 31,  2016  is 
approximately 11 years. The average life is determined by applying 
a  weighted  average  calculation,  using  the  remaining  years  to 
expected maturity of each guaranteed bond, and weighting them 
on the basis of the remaining net par guaranteed. Except for RMBS 
policies, no assumptions are made for non-contractual reductions, 
refundings  or  terminations  of  insured  issues.  RMBS  policies 
incorporate assumptions on expected voluntary and involuntary 
prepayments over the remaining life of the insured obligation.   The

(2)

Includes $125 of military housing net par at December 31, 2016 and 2015.

The decrease in below investment grade exposures is primarily 
due to (i) commutations of student loan policies, (ii) reductions to 
residential mortgage-backed securities during the year as a result 
of both prepayments by issuers and claims presented to Ambac 
Assurance and  (iii)  cancellation  of  certain  asset  backed  bonds. 
Despite  the  decrease  in  below  investment  grade  net  par,  such 
exposure increased in relative proportion to the aggregate insured 
portfolio  to  21%  at  December  31,  2016  compared  to  18%  at 
December 31, 2015.  Based on our experience, below investment 
grade exposures typically run-off at a slower pace than investment 
grade exposures and therefore Ambac is subject to the risk that its 
insured portfolio will increasingly become concentrated in higher 
risk below investment grade exposures.  This risk may result in 
greater volatility in our results from operations and have adverse 
effects on our financial condition.  

U.S. residential mortgage-backed securities exposure 

Ambac  has  exposure  to  the  U.S.  mortgage  market  primarily 
including 
through  direct  financial  guarantees  of  RMBS, 
transactions that contain risks to first and second liens.  

Ambac classifies its insured first-lien RMBS exposure principally 
into  two  broad  credit  risk  classes:  mid-prime  (including Alt-A, 
interest  only,  and  negative  amortization)  and  sub-prime.  Mid-
prime loans were typically made to borrowers who had stronger 
credit profiles relative to sub-prime loans, but weaker than prime 
loans. Compared with mid-prime loans, sub-prime loans typically 
had higher loan-to-value ratios, reflecting the greater difficulty that 

sub-prime  borrowers  have  in  making  down  payments  and  the 
propensity of these borrowers to extract equity during refinancing. 
The mid-prime category includes: 

•

•

Loans  with  specific  payment  features  that  afforded
borrowers the option to have lower payments in the early
years with potential resets after several years. For example,
so-called  interest  only  loans  have  monthly  payments
comprised of interest but no principal. So called negative
amortization loans permit borrowers to defer interest and
principal in the early years and then make higher payments
in the period after the reset. Both types may also have lower
interest  rates  in  the  early  years.  Increases  in  monthly
payments,  commonly  called  payment  shock,  raise  the
probability of delinquencies and defaults given the decline
in  house  prices  that  has  caused  many  borrowers’  loan
balances to exceed their homes’ market value.

for 

agency 

Loans  backed  by  borrowers  who  typically  did  not  meet
documentation
guidelines 
standard 
requirement, property type or loan-to-value ratio. These are
typically  higher-balance  loans  made  to  individuals  who
might  have  past  credit  problems  that  were  not  severe
enough to warrant “sub-prime” classification, or borrowers
who  chose  not  to  obtain  a  prime  mortgage  due  to
documentation requirements.

| Ambac Financial Group, Inc.   16   2016 FORM 10-K |

Ambac's second lien insured RMBS transactions are collateralized 
predominantly by second-lien mortgage loans such as closed-end 
seconds and home equity lines of credit. A second-lien mortgage 
loan is a type of loan in which the borrower uses the equity in their 
home as collateral and the second-lien loan is subordinate to the 
first-lien loan outstanding on the home. The borrower is obligated 
to make monthly payments on both their first and second-lien loans. 
If the borrower defaults on the payments due under these loans and 

the property is subsequently liquidated, the liquidation proceeds 
are first utilized to pay off the first-lien loan (as well as costs due 
the servicer) and any remaining funds are applied to pay off the 
second-lien  loan. As  a  result  of  this  subordinate  position  to  the 
first-lien  loan,  second-lien  loans  carry  a  significantly  higher 
severity in the event of a loss, typically at or above 100% in the 
current housing market.

issuers. As such, we do not expect that our student loan exposure 
will be significantly reduced via refinancing in the near term. 

Auction Rate Securities (“ARS”) and Variable Rate Demand 
Obligations (“VRDO”):

Ambac  insures  variable  rate  obligations  including  ARS  and 
VRDOs, both of which have rate resets and may have experienced 
liquidity and / or credit stress during the financial crisis.  While 
market conditions have improved and most of Ambac’s exposures 
have stabilized or been refinanced away, there are still some issuers 
paying higher rates, and in the case of some VRDOs, both higher 
rates  and  faster  amortization  than  expected  due  to  failed 
remarketings.   Many  of Ambac’s ARS  exposures  are  paying  at 
failed auction rates that are relatively low in the current market 
and  remain  attractive  to  issuers.  The  following  table  sets  forth 
Ambac  Assurance’s  financial  guarantee  net  par  exposure 
outstanding, by bond type, relating to such variable rate exposures 
at December 31, 2016 and 2015:

Student Loans 

Student loan net par outstanding was $1,388 million and $2,323 
million  at  December  31,  2016  and  2015,  respectively.   Ambac 
Assurance’s student loan portfolio consists  primarily of securitized 
private student loans in addition to a minimal amount of federally 
guaranteed  loans  under  the  Federal  Family  Education  Loan 
Program (“FFELP”). Whereas FFELP loans are guaranteed for a 
minimum of 97% of defaulted principal and interest, private loans 
have no government guarantee and, therefore, are subject to credit 
risk  as  with  other  types  of  unguaranteed  credits.  Higher  than 
expected defaults of private student loans have contributed to the 
significant  deterioration  in  the  performance  of  some  of  our 
transactions.  Additionally, due to the failure of the auction rate 
markets, the interest rates on some student loan securities have 
increased significantly to punitive levels pursuant to the transaction 
terms. Such increases have contributed to the collateralization ratio 
in these transactions deteriorating on an accelerated basis due to 
negative excess spread and/or the use of principal receipts to pay 
current interest. The combined increase in defaults and the penalty 
rate  on  the  auction  rate  securities  continue  to  erode  the 
collateralization levels in many of the trusts we insure.  This impact 
has  been  offset  modestly  by  the  current  low  interest  rate 
environment.  

New  private  student  loan  capital  market  transactions  require  a 
significant  amount  of  equity  which  makes  the  refinancing  of 
Ambac insured transactions backed by private loans difficult for

Ambac Assurance  has  reinsurance  in  place  pursuant  to  surplus 
share treaties and facultative agreements. As a primary financial 
guarantor, Ambac Assurance is required to honor its obligations to 
its  policyholders  whether  or  not  its  reinsurers  perform  their 
obligations  under  these  reinsurance  agreements.  For  exposures 
reinsured, Ambac Assurance  withholds  a  ceding  commission  to 
defray its underwriting and operating expenses. To minimize its 
exposure to losses from reinsurers, Ambac Assurance (i) monitors 
the financial condition of its reinsurers; (ii) is entitled to receive 
collateral from its reinsurance counterparties in certain reinsurance 
contracts;  and  (iii) has  certain  cancellation  rights  that  can  be 
exercised  by  Ambac  Assurance  in  the  event  of  rating  agency 
downgrades  of  a 
(among  other  events  and 
circumstances).  Ambac  Assurance  held  letters  of  credit  and 
collateral  amounting  to  $122.9  million  from  its  reinsurers  at 
December 31,  2016.  As  of  December 31,  2016,  the  aggregate 
amount of insured par ceded by Ambac Assurance to reinsurers 
under reinsurance agreements was $7,027 million, with the largest 
reinsurer  accounting  for  $6,086  million  or  7.0%  of  gross  par 
outstanding at December 31, 2016.

Insurance Regulatory Matters 

United States 

Ambac Assurance  and  Everspan  are  domiciled  in  the  State  of 
Wisconsin  and,  as  such,  are  subject  to  the  insurance  laws  and 
regulations of the State of Wisconsin (the “Wisconsin Insurance 
Laws”)  and  are  regulated  by  the  OCI.  In  addition,  Ambac 
Assurance  and  Everspan  are  subject  to  the  insurance  laws  and 
regulations of the other jurisdictions in which they are licensed. 
Under  Wisconsin  insurance  law,  the  Segregated  Account  is  a 
separate  insurer  for  purposes  of  the  Segregated  Account 
Rehabilitation Proceedings. The Segregated Account is separately 
licensed in the State of Wisconsin but not elsewhere, and is under 
the control of, and is overseen by, the Rehabilitator. 

Insurance laws and regulations applicable to financial guarantee 
insurers vary by jurisdiction. The laws and regulations generally 
require  financial  guarantors  to  maintain  minimum  standards  of 
business conduct and solvency; to meet certain financial tests; and 
to file policy forms, premium rate schedules and certain reports 
with  regulatory  authorities,  including  information  concerning 
capital  structure,  ownership,  financial  condition  and  enterprise 
risk.  Regulated  insurance  companies  are  also  required  to  file 
quarterly  and  annual  statutory  financial  statements  with  the 
National Association of Insurance Commissioners (“NAIC”), and 
in  each  jurisdiction  in  which  they  are  licensed.  The  level  of 
supervisory authority that may be exercised by non-domiciliary 
insurance  regulators  varies  by  jurisdiction.  Generally,  however, 
non-domiciliary regulators are authorized to suspend or revoke the 
insurance license they issued and to impose restrictions on that 
license  in  the  event  that  laws  or  regulations  are  breached  by  a 
regulated  insurance  company  or  in  the  event  that  continued  or 
unrestricted  licensing  of  the  regulated  insurance  company 
constitutes a “hazardous condition” in the opinion of the regulator. 

to

including  with 

As the principal, or domiciliary, regulator of Ambac Assurance, 
the Segregated Account and Everspan, OCI has primary regulatory 
authority, 
initiation  and 
administration  of  rehabilitation  or  liquidation  proceedings. 
Additionally, the accounts and operations of Ambac Assurance and 
Everspan are subject to periodic comprehensive examinations by 
the OCI. Wisconsin Insurance Laws require regulated insurance 
companies to maintain minimum standards of business conduct, 
maintain minimum surplus to policyholders, meet certain financial 
tests,  and  file  certain  reports,  including  information  concerning 
their  capital  structure,  ownership,  financial  condition  and 
enterprise  risk. Ambac Assurance,  the  Segregated Account,  and 
Everspan are not subject to risk-based capital requirements, since 
they  are  financial  guarantee  insurers.  Ambac  Assurance,  the 
Segregated  Account  and  Everspan  are  in  compliance  with 
minimum surplus levels. Wisconsin Insurance Laws also require 
prior  approval  by  OCI  of  certain  transactions  between Ambac 
Assurance or Everspan and their respective affiliates. As described 
in  Note  1.  Background  and  Business  Description  to  the 
Consolidated Financial Statements included in Part II, Item 8 in 
this Form 10-K, the Rehabilitator of the Segregated Account has 
imposed  certain  constraints  upon  Ambac  Assurance  through 
contractual  covenants  made  for  the  benefit  of  the  Segregated 
Account and has assumed the authority to control the management 
of the Segregated Account. 

In addition, pursuant to the terms of the Settlement Agreement, 
Ambac Assurance  must  seek  prior  approval  by  OCI  of  certain 

corporate actions. The Settlement Agreement includes covenants 
which generally restrict the operations of Ambac Assurance and 
remain  in  force  until  the  surplus  notes  that  were  issued  to  the 
counterparties  by Ambac Assurance  pursuant  to  the  Settlement 
Agreement  have  been  redeemed,  repurchased  or  repaid  in  full. 
Certain of these restrictions may be waived with the approval of a 
majority of Unaffiliated Qualified Directors (described below), the 
OCI, and/or the requisite percentage of holders of surplus notes 
issued in connection with the Settlement Agreement. Pursuant to 
the Settlement Agreement, Ambac Assurance amended its articles 
of incorporation to require that at least one-third (and, in any event, 
not less than three members) of the board of directors of Ambac 
Assurance must be Unaffiliated Qualified Directors (as defined in 
the Settlement Agreement). If at any time Ambac Assurance does 
not have the requisite number of Unaffiliated Qualified Directors 
to authorize an action that is otherwise restricted by the Settlement 
Agreement, it will need to seek the approval of OCI to take such 
action. 

New  York’s  comprehensive  financial  guarantee  insurance  law 
defines the scope of permitted financial guarantee insurance and 
governs the conduct of business of all financial guarantors licensed 
to  do  business  in  New  York,  including Ambac Assurance  and 
Everspan. The New York financial guarantee insurance law also 
establishes  single  risk  and  aggregate  limits  with  respect  to 
obligations insured by financial guarantee insurers. Such single 
risk  limits  are  specific  to  the  type  of  insured  obligation  (for 
example, municipal or asset-backed). Under the aggregate limits, 
policyholders’ surplus and contingency reserves must at least equal 
a percentage of aggregate net liability that is equal to the sum of 
various percentages of aggregate net liability for various categories 
of specified obligations. At December 31, 2016, Ambac Assurance 
is in compliance with applicable aggregate risk limits but not in 
compliance with applicable single risk limits. Through run-off of 
the portfolio, Ambac Assurance will continue to seek the reduction 
in its exposure to maintain its compliance with applicable single 
and aggregate risk limits, but may not be able to do so. Everspan 
is in compliance with all of such limits. 

United Kingdom 

The  Prudential  Regulatory  Authority  ("PRA")  and  Financial 
Conduct Authority ("FCA") (and their predecessor regulator the 
Financial Services Authority (“FSA”)) have exercised significant 
oversight  of  Ambac  UK  since  2008,  after  Ambac,  Ambac 
Assurance and Ambac UK began experiencing financial stress.  In 
2009, Ambac UK’s license to write new business was curtailed by 
the FSA and the insurance license was limited to undertaking only 
run-off related activity. As such, Ambac UK is authorized to run-
off its insurance portfolio in the United Kingdom, and to do the 
same through a branch in Milan, Italy, and a number of other EU 
countries.  EU  legislation  has  allowed  Ambac  UK  to  conduct 
business in EU states other than the United Kingdom through a 
“passporting”  arrangement,  which  eliminates  the  necessity  of 
those  other  EU 
additional 
jurisdictions. 

licensing  or  authorization 

in 

Ambac UK remains subject to regulation by the PRA and FCA in 
the conduct of its business. The PRA and FCA are the dual statutory 
regulators responsible for regulating the financial services industry 
in  the  United  Kingdom,  with  the  purpose  of  maintaining 
confidence  in  the  U.K.  financial  system,  providing  public 
understanding  of  the  system,  securing  the  proper  degree  of 
protection for consumers and helping to reduce financial crime. In

addition,  the  regulatory  regime  in  the  United  Kingdom  must 
comply  with  certain  EU  legislation  binding  on  all  EU  member 
states. 

Applicable rules require that non-life insurance companies such 
as Ambac UK maintain a margin of solvency at all times in respect 
of the liabilities of the insurance company, the calculation of which 
depends on the type and amount of insurance business a company 
writes. These solvency requirements have been amended in order 
to  implement  the  European  Union’s  “Solvency  II”  directive  on 
risk-based capital. The requirements of the Solvency II directive 
became effective on January 1, 2016.

Notwithstanding the foregoing, Ambac UK is deficient in terms of 
compliance with the applicable regulatory capital requirements as 
of December 31, 2016 under the Solvency II directive.  The PRA 
and FCA are aware of the same, and dialogue between Ambac UK 
management and its regulators remains ongoing with respect to 
options  for  addressing  the  shortcoming,  although  such  options 
remain few. 

Regulations over change in control 

Under Wisconsin law applicable to insurance holding companies, 
any acquisition of control of Ambac, and any other direct or indirect 
control  of  Ambac  Assurance  and  Everspan,  requires  the  prior 
approval of the OCI. “Control” is defined as the direct or indirect 
power  to  direct  or  cause  the  direction  of  the  management  and 
policies  of  a  person.  Any  purchaser  of  10%  or  more  of  the 
outstanding  voting  stock  of  a  corporation  is  presumed  to  have 
acquired control of that corporation and its subsidiaries unless the 
OCI, upon application, determines otherwise. For purposes of this 
test, Ambac believes that a holder of common stock having the 
right to cast 10% or more of the votes which may be cast by the 
holders of all shares of common stock of Ambac would be deemed 
to  have  control  of Ambac Assurance  and  Everspan  within  the 
meaning of the Wisconsin Insurance Laws. The United Kingdom 
has similar requirements applicable in respect of Ambac, as the 
ultimate holding company of Ambac UK. 

Dividend Restrictions, Including Contractual Restrictions 

Due to contractual and regulatory restrictions, Ambac Assurance 
has been unable to pay common dividends to Ambac since 2008 
and  will  be  unable  to  pay  common  dividends  in  2017  without 
certain approvals, including the prior consent of the OCI, which 
is unlikely. See Note 8. Insurance Regulatory Restrictions to the 
Consolidated Financial Statements included in Part II, Item 8 in 
this Form 10-K for further information on dividends. 

Ambac Assurance’s ability to pay dividends is further restricted 
by the Settlement Agreement and by certain covenants made for 
the benefit of the Segregated Account. See Note 1. Background 
and Business Description to the Consolidated Financial Statements 
included in Part II, Item 8 in this Form 10-K for further information 
about covenants made for the benefit of the Segregated Account. 

As a result of these restrictions, Ambac Assurance is not expected 
to pay dividends to Ambac for the foreseeable future. 

Ambac  UK  is  not  expected  to  pay  any  dividends  to  Ambac 
Assurance  for  the  foreseeable  future.  While  the  UK  insurance 
regulatory laws impose no statutory restrictions on an insurer’s 
ability  to  declare  a  dividend,  the  PRA’s  and  FCA’s  capital 
requirements  in  practice  act  as  a  restriction  on  the  payment  of 

dividends, where a firm has a lower level of regulatory capital than 
its regulatory capital requirement as is the case for Ambac UK. 
Further, the FSA amended Ambac UK’s license in 2010 such that 
the PRA must specifically approve (“non-objection”) any transfer 
of value and/or assets from Ambac UK to Ambac Assurance or any 
other Ambac  group  company,  other  than  in  respect  of  certain 
disclosed contracts between the two parties (such as in respect of 
a management services agreement between Ambac Assurance and 
Ambac UK).

Pursuant to the Settlement Agreement, Ambac Assurance may not 
make any “Restricted Payment” (which includes dividends from 
Ambac  Assurance  to  Ambac)  in  excess  of  $5  million  in  the 
aggregate per annum, other than Restricted Payments from Ambac 
Assurance to Ambac in an amount up to $7.5 million per annum 
solely  to  pay  operating  expenses  of  Ambac.  Concurrent  with 
making  any  such  Restricted  Payment,  a  pro  rata  amount  of  the 
surplus  notes  issued  by Ambac Assurance  under  the  Settlement 
Agreement would also need to be redeemed at par. 

Under the terms of Ambac Assurance’s Auction Market Preferred 
Shares (“AMPS”), dividends may not be paid on the common stock 
of Ambac Assurance unless all accrued and unpaid dividends on 
the AMPS for the then current dividend period have been paid, 
provided, that dividends on the common stock may be made at all 
times for the purpose of, and only in such amounts as are necessary 
for, enabling Ambac (i) to service its indebtedness for borrowed 
money as such payments become due or (ii) to pay its operating 
expenses. If dividends are paid on the common stock as provided 
in the prior sentence, dividends on the AMPS become cumulative 
until the date that all accumulated and unpaid dividends have been 
paid on the AMPS.

FINANCIAL SERVICES SEGMENT

Ambac’s  Financial  Services  business  segment  is  conducted 
through subsidiaries of Ambac Assurance, which provide financial 
and  investment  products,  including  investment  agreements, 
funding conduits and interest rate swaps, principally to the clients 
of its financial guarantee business. Ambac Assurance insures all 
of  the  obligations  of  its  financial  services  subsidiaries.  These 
businesses  are  in  active  runoff,  which  is  being  effectuated  by 
transaction terminations, settlements, and scheduled amortization 
of  contracts.  The  Financial  Services  business  also  maintains 
interest rate derivatives to mitigate exposure to floating rate insured 
obligations in the Financial Guarantee segment. 

The  principal  factors  that  may  affect  the  Financial  Services 
Segment  results  include:  (1) availability  of  counterparties  for 
economic  hedging  transactions;  (2) investment  returns;  (3) the 
value  of  future  contract  terminations  or  settlements  which  may 
differ  from  carrying  value  of  the  those  contracts;  (4) collateral 
posting requirements; (5) the availability of liquidity from Ambac 
Assurance; (6) changes in the fair value of the derivatives portfolio 
resulting from interest rate fluctuations; (7) timing of investment 
agreement withdrawals; and (8) restrictions imposed upon Ambac 
Assurance by the contracts executed with the Segregated Account 
and  the  Settlement Agreement,  and,  to  the  extent  that  policies 
allocated to the Segregated Account are implicated, the authority 
of  the  Rehabilitator  of  the  Segregated  Account  to  control  the 
management of the Segregated Account.

Investment Agreements 

Ambac’s investment agreements were issued to structured finance 
and  municipal  issuers  through  its  wholly-owned  subsidiary, 
Ambac Capital Funding. Investment agreements were customized 
for  each  investor  to  provide  guaranteed  interest  and  return  of 
principal in accordance with their requirements. Each investment 
agreement was insured by Ambac Assurance through a financial 
guarantee insurance policy. 

As of December 31, 2016, all investment agreement principal and 
accrued interest outstanding of $82.4 million was collateralized. 
Funding  for  the  collateral  and  previous  early  terminations  was 
supported in part through loans between Ambac Capital Funding 
and Ambac Assurance. Ambac Capital Funding's last remaining 
investment agreement matures in March 2017.

See  “Liquidity  and  Capital  Resources”  of  the  Management’s 
Discussion  and Analysis  of  Financial  Condition  and  Results  of 
Operations” included in Part II, Item 7 and Note 14. Obligations 
Under  Investment  Agreements  to  the  Consolidated  Financial 
Statements included in Part II, Item 8 in this Form 10-K for further 
information on investment agreements. 

Derivative Products 

The primary activities in the derivative products business are to 
manage the runoff of derivatives with financial guarantee clients 
and  to  facilitate  the  mitigation  of  interest  rate  exposure  for  the 
Financial Guarantee segment via swaps and exchange traded U.S. 
treasury  futures.  Derivative  transactions  are  executed  through 
Ambac Financial Services (“AFS”), a wholly-owned subsidiary of 
Ambac Assurance. The derivative products portfolio is positioned 
to benefit from rising rates as an economic hedge against interest 
rate exposure in the financial guarantee insurance portfolio. This 
hedge position may have a significant impact on the results of the 
Financial Services segment. Under the agreements governing the 
derivative positions, AFS generally must post collateral or margin 
in excess of the market value of the swaps and futures contracts. 
In  addition,  most  of AFS’s  counterparties  currently  possess  the 
right to terminate their transactions with AFS and in the event of 
a full rehabilitation of Ambac Assurance, some of AFS’s swaps 
could  automatically  terminate. A  sudden  termination  of AFS’s 
derivatives, whether voluntarily or automatically, could result in 
losses.  AFS  has  borrowed  cash  and  securities  from  Ambac 
Assurance, to help support its incremental collateral and margin 
posting  requirements,  previous  termination  payments  and  other 
cash needs. 

Credit risks relating to derivative positions primarily concern the 
default  of  a  counterparty.  Counterparty  default  exposure  is 
mitigated through the use of industry standard collateral posting 
agreements. For counterparties subject to such collateral posting 
agreements, collateral is posted when a derivative counterparty’s 
credit  exposure  exceeds  contractual  limits.  Derivative  contracts 
entered into with financial guarantee customers are not subject to 
collateral  posting  agreements.  Credit  risk  associated  with  such 
customer  derivatives,  including  credit  derivatives,  is  managed 
through  the  financial  guarantee  portfolio  risk  management 
processes  described  in  the  Financial  Guarantee  Segment  noted 
above. In some cases, derivatives between Ambac and financial 
guarantee  customers  are  placed  through  a  third  party  financial 
intermediary and similarly do not require collateral posting.

AFS manages a variety of market risks inherent in its businesses, 
including  credit,  market,  liquidity,  operational  and  legal. These 
risks are identified, measured, and monitored through a variety of 
control  mechanisms,  which  are  in  place  at  different  levels 
throughout  the  organization.  See  “Quantitative  and  Qualitative 
Disclosures About Market Risk” included in Part II, Item 7A in 
this Form 10-K for further information. 

Funding Conduits 

A subsidiary of Ambac has previously transferred financial assets 
to  two  special  purpose  entities.  The  business  purpose  of  these 
entities  was  to  provide  certain  financial  guarantee  clients  with 
funding  for  their  debt  obligations.  The  activities  of  the  special 
purpose entities are contractually limited to purchasing assets from 
Ambac,  issuing  medium-term  notes  (“MTNs”)  to  fund  such 
purchases,  executing  derivative  hedges  and  obtaining  financial 
guarantee policies with respect to indebtedness incurred.  As of 
December 31,  2016, Ambac Assurance  had  financial  guarantee 
insurance  policies  issued  for  all  assets,  MTNs  and  derivative 
contracts owned and outstanding by the entities. Ambac does not 
consolidate these entities under the relevant accounting guidance 
for consolidation of variable interest entities. See Note 2. Basis of 
Presentation  and  Significant  Accounting  Policies  and  Note  3. 
Special Purpose Entities, Including Variable Interest Entities to 
the Consolidated Financial Statements included in Part II, Item 8 
in this Form 10-K for further information. 

INVESTMENTS AND INVESTMENT POLICY

As of December 31, 2016, the consolidated non-VIE investments 
of Ambac had an aggregate fair value of approximately $6.5 billion. 
Investments are managed internally by officers of Ambac, who are 
experienced  investment  managers,  and  by  external  investment 
managers. All investments are made in accordance with the general 
objectives, policies, and guidelines for investments reviewed or 
overseen by Ambac Assurance and Ambac UK’s respective Boards 
of Directors.  These policies and guidelines  include liquidity, credit 
quality, diversification and duration objectives and are periodically 
reviewed  and  revised  as  appropriate. Additionally,  senior  credit 
personnel  monitor  the  portfolio  on  a  continuous  basis.  Credit 
monitoring  of  the  investment  portfolio  includes  procedures  on 
residential  mortgage-backed  securities  consistent  with  those 
utilized to assess the risk of our insured RMBS exposures. 

As  of  December 31,  2016,  the Ambac Assurance  and  Everspan 
non-VIE  investment  portfolio  had  an  aggregate  fair  value  of 
approximately  $5.5  billion. Ambac Assurance’s  and  Everspan’s 
investment objectives are to achieve the highest risk-adjusted after-
tax  return  on  a  diversified  portfolio  consistent  with  Ambac 
Assurance’s and Everspan’s risk tolerance while employing active 
asset/liability management practices to satisfy all operating and 
strategic liquidity needs. In addition to internal investment policies 
and guidelines, Ambac Assurance’s investment portfolio is subject 
to limits on types and quality of investments imposed by applicable 
insurance laws and regulations. The Board of Directors of Ambac 
Assurance  approves  any  changes 
to  Ambac  Assurance's 
investment policy.  Ambac Assurance purchases Ambac Assurance 
insured securities given their relative risk/reward characteristics. 
Ambac Assurance financial guarantee policies related to most of 
these securities have been allocated to the Segregated Account. As 
described in Note 1. Background and Business Description to the 
Consolidated Financial Statements included in Part II, Item 8 in 
this  Form  10-K,  Ambac  Assurance’s  investment  policies  are 

| Ambac Financial Group, Inc.   21   2016 FORM 10-K |

subject to certain covenants made for the benefit of the Segregated 
Account and, therefore, such policies may be subject to restrictions 
outside  the  control  of  management.  Such  covenants  could 
adversely impact the performance of the investment portfolio. 

As  of  December 31,  2016,  the  non-VIE Ambac  UK  investment 
portfolio had an aggregate fair value of approximately $0.6 billion. 
Ambac  UK’s  investment  policy  is  designed  with  the  primary 
objective of ensuring that Ambac UK is able to meet its financial 
obligations as they fall due, in particular with respect to policy 
holders  and  meeting  their  claims.  Ambac  UK’s  investment 
portfolio is subject to internal investment guidelines and may be 
subject to limits on types and quality of investments imposed by 
its regulator. The Board of Directors of Ambac UK approves any 
changes or exceptions to Ambac UK’s investment policy. 

As  of  December 31,  2016,  the  non-VIE  Financial  Services

to Ambac and its subsidiaries, as the context requires. Capitalized 
terms used but not defined in this section shall have the meanings 
ascribed thereto in Part I, Item 1 in this Form 10-K or in Note 1. 
Background  and  Business  Description  to  the  Consolidated 
Financial Statements included in Part II, Item 8 in this Form 10-
K unless otherwise indicated. 

Risks Related to Ambac Common Shares

Investments  in Ambac's  common  stock  are  highly  speculative 
and the price per share of Ambac's common stock may be subject 
to a high degree of volatility, including significant price declines.

Ambac's  common  stock,  which  was  issued  pursuant  to  its 
Reorganization  Plan,  began  trading  on  the  NASDAQ  Global 
Market on May 1, 2013. Although Ambac's common stock is listed 
on NASDAQ, there can be no assurance as to the liquidity of the 
trading market or the price at which such shares can be sold.  The 
price  of  the  shares  may  decline  substantially  in  response  to  a 
number of events or circumstances, including but not limited to:

•

•

•

•

•

•

•

adverse developments in our financial condition or results
of operations;

changes in the actual or perceived risk within our insured
portfolio;

changes to regulatory status;

changes in investors’ or analysts’ valuation measures for
our stock;

market trends unrelated to our stock;

market  and  industry  perception  of  our  success,  or  lack
thereof, in pursuing our business strategy; and

results and actions of other participants in our industry.

In addition, the price of Ambac's shares may be affected by the 
additional risks described below, including risks associated with 
Ambac Assurance’s ability to deliver value to Ambac.  Investments 
in Ambac's common stock should be considered highly speculative 
and may be subject to a high degree of volatility.

Ambac may not be able to realize value from Ambac Assurance 
or generate earnings apart from Ambac Assurance.

Because Ambac  is  a  holding  company,  the  value  of  its  stock  is 
dependent upon the residual value of its main operating subsidiary, 
Ambac Assurance, the receipt of payments to be made by Ambac 
Assurance pursuant to the Amended TSA and the Cost Allocation 

Agreement, the receipt of payments on the Owner Trust Certificate 
issued to Ambac by Corolla Trust (the "Owner Trust Certificate"), 
the receipt of payments on investments made on securities issued 
or insured by Ambac Assurance or the Segregated Account, and 
the receipt of dividends from Ambac Assurance. There can be no 
assurance  that Ambac  will  be  able  to  realize  residual  value  in 
Ambac Assurance, which is in run-off. In addition, the Segregated 
to 
Account  of  Ambac  Assurance  Corporation 
rehabilitation  proceedings  and  under 
the 
Rehabilitator,  as  further  described  below.  It  is  unclear  whether 
Ambac Assurance  and  the  Segregated Account  will  be  able  to 
satisfy all of their respective obligations to policyholders, holders 
of their respective surplus notes and holders of Ambac Assurance’s 
preferred  stock,  even  if Ambac Assurance  and  the  Segregated 
Account  are  successful  in  achieving  recoveries  and  mitigating 
losses.  Our  ability  to  achieve  recoveries  and  mitigate  losses  is 
subject to significant risks and uncertainties, including as a result 
of varying potential perceptions of the value of Ambac Assurance’s 
guarantees and securities.

is  subject 
the  control  of 

Due to the above considerations, as well as applicable legal and 
contractual  restrictions  described  elsewhere  herein,  it  is  highly 
unlikely  that Ambac Assurance  will  be  able  to  pay Ambac  any 
dividends for the foreseeable future. Furthermore, the payments to 
be made to Ambac under the Amended TSA and the Cost Allocation 
Agreement are subject to contingencies that are difficult to predict, 
making the amount and timing, if any, of such payments uncertain. 
Payments  to  be  made  under  the Amended  TSA,  in  particular, 
depend  on  the  generation  of  future  taxable  income  by Ambac 
Assurance above certain thresholds. Ambac Assurance’s ability to 
generate taxable income above such thresholds is uncertain. Due 
to these factors, there can be no assurance as to the amounts that 
Ambac will receive from Ambac Assurance under the Amended 
TSA.    Moreover,  the  Cost Allocation Agreement  provides  that 
Ambac Assurance's reimbursement of Ambac's operating expenses 
after 2017 is subject to the approval of the Rehabilitator and limited 
to $4.0 million per annum.  We can provide no assurance as to 
whether the Rehabilitator will approve such reimbursement or any 
portion thereof.

It is also uncertain whether and to what extent Ambac will realize 
value  from  the  Owner  Trust  Certificate.  The  Owner  Trust 
Certificate  is  subordinated  to  $299.2  million  of  senior  secured 
notes issued by Corolla Trust.  Such notes and the Owner Trust 
Certificate are collateralized by and payable solely from a $350.0 
million face amount Segregated Account junior surplus note plus 
interest  thereon.  No  payment  of  interest  on  or  principal  of  a 
Segregated Account  junior  surplus  note  may  be  made  until  all 
existing  and  future  indebtedness  of  the  Segregated  Account, 
including  Segregated Account  surplus  notes,  policy  claims  and 
claims having statutory priority, and all existing and future senior 
ranking surplus notes, contribution notes or similar obligations of 
Ambac Assurance, have been paid in full. All payments of principal 
and interest on Segregated Account junior surplus notes are subject 
to the prior approval of OCI. If OCI does not approve the payment 
of  interest  on  Segregated  Account  junior  surplus  notes,  such 
interest will accrue and compound annually until paid. Payments 
on the senior secured notes issued by Corolla Trust will only be 

| Ambac Financial Group, Inc.   23   2016 FORM 10-K |

made when and to the extent that the Segregated Account makes 
payments on the junior surplus note held by Corolla Trust. The 
senior secured notes must be paid in full before any payments will 
be made on the Owner Trust Certificate. If Corolla Trust has failed 
to pay all interest and principal outstanding on the senior secured 
notes within three business days of August 28, 2039, the senior 
secured noteholders may also take possession of and sell the junior 
surplus note.   If such a sale were to occur, it is uncertain whether 
and to what extent there would be any value for the Owner Trust 
Certificate after satisfaction of the senior secured notes.

The value of Ambac's common stock may also depend upon the 
ability  of  Ambac  to  generate  earnings  apart  from  Ambac 
Assurance.  As  noted  below,  Ambac  is  selectively  exploring 
potential  business  opportunities  that,  among  other  things,  may 
permit utilization of Ambac’s net operating loss carry-forwards, 
but there are no assurances regarding its ability to find or execute 
such  business  opportunities  or  the  prospects  of  any  such 
opportunities.

Future offerings of debt or equity securities that rank senior to 
Ambac's common stock may adversely affect the market price of 
its common stock.

If Ambac decides to issue debt or additional equity securities in 
the future that rank senior to its common stock, it is likely that they 
will be governed by an indenture or other instrument containing 
covenants restricting Ambac's operating flexibility. Additionally, 
any convertible or exchangeable securities issued in the future may 
have rights, preferences and privileges more favorable than those 
of common stock and may result in dilution to owners of common 
stock. Because Ambac's decision to issue debt or equity securities 
in any future offering will depend on market conditions, it cannot 
predict or estimate the amount, timing or nature of future offerings. 
Holders of common stock bear the risk of future offerings reducing 
the market price of Ambac's common stock and diluting the value 
of their stock holdings in the Company. 

The occurrence of certain events could result in the initiation of 
rehabilitation  proceedings  against  Ambac  Assurance,  with 
resulting adverse consequences to holders of our securities. 

Increased  loss  development  in  the  General Account  of Ambac 
Assurance or the Segregated Account or significant losses or other 
events resulting from litigation against Ambac Assurance or the 
Segregated Account may prompt OCI to determine that it is in the 
best interests of policyholders to initiate rehabilitation proceedings 
with  respect  to  Ambac  Assurance,  either  preemptively  or  in 
response  to  any  such  event,  and  in  addition  to  the  Segregated 
Account Rehabilitation Proceedings.

If, as a result of the occurrence of any such event(s), OCI decides 
to  initiate  rehabilitation  proceedings  with  respect  to  Ambac 
Assurance, adverse consequences may result, including, without 
limitation and absent enforceable protective injunctive relief, the 
assertion of damages by counterparties (including mark-to-market 
claims  with  respect  to  insured  transactions  executed  in  ISDA 
format),  the  acceleration  of  losses  based  on  early  termination 
triggers and the loss of control rights in insured transactions. Any 
such  consequences  may  reduce  the  residual  value  of  Ambac 
Assurance. Additionally, the Rehabilitator would assume control 
of  all  of Ambac Assurance’s  assets  and  management  of Ambac 
Assurance. In exercising control, the Rehabilitator would act for 
the benefit of policyholders, and would not take into account the 

interests of our securityholders. Such actions may result in material 
adverse consequences for our securityholders.

The  issuance  of  new  common  stock  may  dilute  current 
shareholder value or have adverse effects on the market price of 
Ambac's common stock.

If Ambac raises capital through the issuance of additional shares 
of common stock, whether for select business transactions, general 
corporate purposes, or in exchange for other securities, the value 
of  current shareholders’ interests may be diluted as Ambac is not 
required  to  offer  any  such  shares  to  existing  stockholders  on  a 
preemptive basis.

Ambac  cannot  predict  the  effect,  if  any,  of  future  sales  of  its 
common stock, or the availability of shares for future sales, on the 
market price of its common stock. Sales of substantial amounts of 
common stock or the perception that such sales could occur may 
adversely affect the prevailing market price for its common stock.

Risks Related to Insured Portfolio Losses

Loss  reserves  may  not  be  adequate  to  cover  potential  losses; 
changes in loss reserves may result in further volatility of net 
income and comprehensive income.

Loss  reserves  are  established  when  management  has  observed 
credit deterioration, in most cases, when the underlying credit is 
considered below investment grade. Loss reserves established with 
respect to our non-derivative financial guarantee insurance policies 
are based upon estimates and judgments by management, including 
estimates and judgments with respect to the probability of default, 
the severity of loss upon default, management’s ability to execute 
policy commutations, and estimated remediation recoveries for, 
among other things, breaches by RMBS issuers of representations 
and  warranties.  Furthermore,  the  objective  of  establishing  loss 
reserve estimates is not to, and our loss reserves do not, reflect the 
worst possible outcome. While our reserving scenarios reflect a 
wide  range  of  possible  outcomes  reflecting  the  significant 
uncertainty regarding future developments and outcomes, our loss 
reserves may change materially based on future developments. As 
a result of the inherent uncertainties in the estimates and judgments 
made to determine loss reserves, there can be no assurance that 
either  the  actual  losses  in  our  financial  guarantee  insurance 
portfolio will not exceed such reserves or that our reserves will not 
increase or decrease materially over time as circumstances, our 
assumptions, or our models change.

Additionally,  inherent  in  our  estimates  of  loss  severities  and 
remediation recoveries is the assumption that we will retain control 
rights in respect of our insured portfolio. However, according to 
the  terms  of  relevant  transaction  documents,  we  may  lose  our 
control rights in many insured transactions if, among other things, 
we  are  the  subject  of  delinquency  proceedings  and/or  other 
regulatory  actions  which  could  result  from  our  deteriorated 
financial position. If we lose control rights, our ability to mitigate 
loss  severities  and  realize  remediation  recoveries  will  be 
compromised, and actual ultimate losses in our insured portfolio 
could exceed our loss reserves.  The Rehabilitation Court issued 
an injunction restraining certain actions by holders of policies in 
the Segregated Account and other parties, including actions based 
on the loss of control rights. If this injunction does not successfully 
preclude  such  actions, Ambac Assurance  could  lose  its  control 
rights with respect to certain policies in the Segregated Account.

Some  issuers  of  public  finance  obligations  we  insure  are 
experiencing fiscal stress that could result in increased losses on 
those obligations or increased liquidity claims, including losses 
or claims resulting from payment defaults, Chapter 9 bankruptcy 
or other restructuring proceedings or loss of market access.

We  have  historically  experienced  low  levels  of  defaults  in  our 
public  finance  insured  portfolio,  including  during  the  financial 
crisis that began in mid-2007. However, some issuers of public 
finance obligations we insure continue to report budget shortfalls, 
significantly underfunded pensions or other fiscal stresses that will 
require  them  to  significantly  raise  taxes  and/or  cut  spending  in 
order to satisfy their obligations. Government entities may also 
take other actions that may impact their own creditworthiness or 
the creditworthiness of related issuers. Some issuers of obligations 
we insure have declared a payment moratorium, defaulted or filed 
for  bankruptcy,  raising  concerns  about  their  ultimate  ability  to 
service the debt we insure and our ability to recover claims paid 
in the future. If the issuers of the obligations in our public finance 
portfolio are unable to raise taxes, cut spending, or receive federal 
or state assistance, or if such issuers default or file for bankruptcy 
under  Chapter  9,  we  may  experience  liquidity  claims  and/or 
ultimate losses on those obligations, which could adversely affect 
our business, financial condition and results of operations.

We  insure  obligations  of  several  issuers  that  have  filed  for 
bankruptcy protection under Chapter 9. The consequences of such 
proceedings  for  creditors  remain  uncertain. For  example,  the 
treatment of general obligation debt in relation to other obligations 
remains in flux, with Detroit's 2014 precedent unfavorable for debt 
creditors. If 
their 
obligations to bondholders and financial guarantors, other issuers 
may be encouraged to default or file for Chapter 9 protection and 
seek  similar  adjustments  to  their  debt. These  events  could 
materially  increase  losses  in  Ambac’s  insured  portfolio  of 
municipal credits.

in  materially  adjusting 

issuers  succeed 

Loss  of  market  access  is  a  risk  embedded  in  our  municipal 
exposures. From time to time the municipal bond market evidences 
heightened investor concerns overall or for select sectors or issuers, 
as  has  been  the  case  with  Puerto  Rico. Such  adverse  market 
conditions  may  trigger  a  loss  of  market  liquidity  for  affected 
issuers,  which  in  turn  may  significantly  raise  their  cost  of 
alternative financing or cause a liquidity crisis and potential for 
default on debt service payments we guarantee.

As of December 31, 2016, we had $2.1 billion of net par exposure 
to the Commonwealth of Puerto Rico, including its affiliates and 
public  corporations.    Components  of  Puerto  Rico  net  par 
outstanding include capital appreciation bonds that are reported at 
the  par  amount  at  the  time  of  issuance  of  the  related  insurance 
policy. The Commonwealth has announced that it cannot meet its 
obligations and that it intends to impair some or all of its creditors. 
In  April  2016,  the  Commonwealth  enacted  the  Puerto  Rico 
Emergency Moratorium and Financial Rehabilitation Act, which 
the then Governor of Puerto Rico invoked to, among other things, 
prevent the payment of debt service owed by several issuers. The 
Commonwealth and certain of its instrumentalities have defaulted 
on a portion of their debt service payments, including payments 
owed on bonds insured by Ambac Assurance. Ambac Assurance 
may be required to make significant amounts of policy payments 
over the next several years, the recoverability of which is subject 
to great uncertainty, which may lead to material permanent losses. 
Our  exposure  to  Puerto  Rico  is  impacted  by  the  Puerto  Rico 

economy, which may be impacted by factors such as perceptions 
regarding  its  ability  to  maintain  appropriate  infrastructure 
standards. Given our exposure to Puerto Rico and the economic, 
legal  and  political  uncertainties  associated  therewith,  our  loss 
reserves may ultimately prove to be insufficient to cover our losses, 
potentially by a material amount, and may be subject to material 
volatility.

The Commonwealth has proposed to restructure and renegotiate 
its  obligations  and  those  of  certain  of  its  affiliates  and  public 
corporations. Alternatives could be proposed or adopted that could 
significantly  impair  our  exposures,  including  by  failing  to 
recognize or properly differentiate legal structures and protections 
applicable to such exposures, such that our loss reserves would 
need to be increased. In June 2016, the United States enacted the 
Puerto Rico Oversight, Management, and Economic Stability Act 
(“PROMESA”).  Among  other  things,  PROMESA  contains 
provisions  that  may  permit  consensual  and  non-consensual 
restructurings of debt obligations of the Commonwealth and its 
instrumentalities under the auspices of an oversight board created 
thereunder, subject to compliance with PROMESA. At this time, 
Ambac is unable to predict to what extent debt restructurings will 
be  proposed  or  implemented  under  PROMESA,  and  what  such 
restructurings  or  renegotiations  would  entail.  PROMESA  also 
contains a temporary stay on litigation, which has been extended 
to  May  1,  2017,  thus  potentially  limiting  Ambac  Assurance’s 
ability to engage in loss mitigation. Litigation challenging the legal 
protections on which Ambac Assurance and its insured exposures 
rely is likely to intensify, which may materially increase our risk 
of loss. On October 7, 2016, certain holders of Puerto Rico’s GO 
bonds requested leave of court to file an amended complaint that, 
among other things, challenges the structure of the Puerto Rico 
Sales  Tax  Financing  Corporations  ("COFINA")  and  seeks 
injunctive relief requiring the sales and use tax proceeds securing 
the  bonds  issued  by  COFINA  to  be  transferred  to  the 
Commonwealth treasury for payment of GO bonds.  On October 
26, 2016, Ambac filed a motion to intervene in that lawsuit in order 
to  argue  that  the  proposed  claims  are  subject  to  PROMESA’s 
litigation stay, and reserving the right to move to dismiss the claims 
should the Court determine they are not stayed. On February 17, 
2017, the Court granted Ambac's motion to intervene and ruled 
that the claims challenging the COFINA structure are not subject 
to litigation stay. If successful, the GO plaintiffs’ challenge against 
COFINA, and any similar claims that could be asserted by other 
plaintiffs in the future, could have a significant negative impact on 
Ambac’s liquidity, loss reserves and capital resources. While our 
reserving  scenarios  reflect  a  wide  range  of  possible  outcomes 
reflecting 
future 
developments and outcomes, there could be material variability in 
our  loss  reserves  for  the  foreseeable  future  given  the  fluid  and 
unpredictable situation concerning the debts of Puerto Rico and its 
instrumentalities.

We  are  subject  to  credit  risk  and  other  risks  in  our  insured 
portfolio, including related to RMBS and securities backed by 
student loans. We are also subject to risks associated with adverse 
selection as our insured portfolio runs off. Measures taken to 
reduce such risks may have an adverse effect on operating results 
or financial position.

Performance of our insured transactions, including (but not limited 
to) RMBS transactions and those involving securities backed by 
student  loans,  can  be  adversely  affected  by  general  economic 

| Ambac Financial Group, Inc.   25   2016 FORM 10-K |

conditions,  such  as  recession,  rising  unemployment  rates, 
underemployment, home prices that decline or do not increase in 
the patterns assumed in our models, increasing foreclosure rates 
and unavailability of consumer credit, mortgage product attributes, 
such as interest rate adjustments and balloon payment obligations, 
borrower  and/or  originator  fraud,  mortgage  and  student  loan 
servicer performance or underperformance and financial difficulty, 
such as risks related to whether the servicer may be required to 
delay the remittance of any cash collections held by it or received 
by it after the time it becomes subject to bankruptcy or insolvency 
proceedings.

While further deterioration in the performance of consumer assets, 
including mortgage-related assets and student loans, may occur, 
the timing, extent and duration of any future deterioration of the 
credit  markets  is  unknown,  as  is  the  impact  on  potential  claim 
payments  and  ultimate  losses  on  the  securities  within  Ambac 
Assurance’s portfolio. In addition, there can be no assurance that 
any governmental or private sector initiatives designed to address 
such credit deterioration in the markets will be successful or inure 
to  the  benefit  of  the  transactions  we  insure. For  example,  any 
initiative  which  permits  the  discharge  of  student  loan  debt  in 
bankruptcy may adversely affect our portfolio. Similarly, servicer 
settlements with governmental authorities regarding foreclosure 
or  servicing  irregularities  are  generally  designed  to  protect 
borrowers  and  may  increase  losses  on  securities  we  insure.  In 
particular, the student loan industry has been subject to heightened 
Consumer  Finance  Protection  Bureau  (CFPB)  scrutiny  over 
servicing  and  collections  practices  and,  consequently,  any 
settlements  resulting  from  this  scrutiny  could  lead  to  increased 
losses on securities we insure.

In addition, there can be no assurance that we would be successful, 
or that we would not be delayed, in enforcing the subordination 
provisions, credit enhancements or other contractual provisions of 
the RMBS that Ambac Assurance insures.

As the runoff of the insured portfolio continues, the proportion of 
exposures  we  rate  as  below  investment  grade  relative  to  the 
aggregate insured portfolio is likely to continue to increase, leaving 
the portfolio increasingly concentrated in higher risk exposures.  
This risk may result in greater volatility or have adverse effects on 
our results from operations and on our financial condition.  

One of our primary goals is to create shareholder value through 
transaction  terminations,  policy  commutations,  settlements  and 
restructurings that we believe will improve our risk profile.  As we 
take such actions to reduce known and potential risks, such actions 
may negatively impact our operating results or financial position 
in one or more reporting periods.

Our  credit  risk  management  policies  and  practices  may  not 
adequately identify significant risks.

As described in Part I, Item 1, “Risk Management” in this Form 
10-K, we have established risk management policies and practices 
which seek to mitigate our exposure to credit risk in our insured 
portfolio.  Ongoing  surveillance  of  credit  risks  in  our  insured 
portfolio is an important component of our risk management. These 
policies and practices in the past have not insulated us from risks 
that were unforeseen and which had unanticipated loss severity, 
and such policies and practices may not do so in the future. There 
can  be  no  assurance  that  these  policies  and  practices  will  be 
adequate  to  avoid  future  losses.  If  we  are  not  able  to  identify 

significant risks, we may not be able to timely remediate such risks, 
thereby increasing the amount of losses to which we are exposed. 
An inability to identify significant risks could also result in the 
failure to establish loss reserves that are sufficient in relation to 
such risks.

We use analytical models to assist our projection of performance 
of our insured obligations and our investment portfolio but actual 
results could differ materially from the model outputs and related 
analyses.

We rely on internally and externally developed complex financial 
models, including default models related to RMBS and waterfall 
modeling provided by a nationally recognized vendor for RMBS 
and student loan exposures, to project performance of our insured 
obligations  and  related  securities  in  our  investment  portfolio. 
These models assume various conditions, probability scenarios, 
facts and circumstances, and there can be no assurance that such 
models accurately predict or measure the quantum of losses, loss 
reserves and timing of losses. Differences in the models that we 
employ, and/or uncertainties and/or flaws in these financial models 
and/or faulty assumptions inherent in these financial models and 
those determined by management, could lead to material changes 
in  projected  outcomes,  and  could  include  increased  losses,  loss 
reserves  and/or  other  than  temporary  investment  impairments. 
Moreover, modeled estimates of transaction performance depend 
in part on our interpretations of contracts and other bases of our 
legal  rights.  Such  interpretations  may  prove  to  be  incorrect  or 
different interpretations may be employed by bond trustees and 
other transaction participants and, ultimately courts, which could 
lead  to  increased  losses,  loss  reserves  and/or  investment 
impairments.

Potential  outcome  of  litigation  relating  to  certain  military 
housing credit exposures could adversely affect Ambac.

Ambac Assurance is a party to a number of litigations relating to 
military  housing  securitization  credits,  where  opposing  parties 
contend that, among other things, Ambac Assurance has lost its 
control rights due to the existence of an “Ambac Default” caused 
by,  among  other  things,  the  Segregated Account  Rehabilitation 
Proceedings.  If Ambac Assurance is found to have lost control 
rights in these transactions, our ability to mitigate losses could be 
significantly  compromised,  and  actual  ultimate  losses  in  these 
military  housing  transactions  could  exceed  our  current  loss 
reserves. Moreover, an adverse outcome relating to the assertion 
of an “Ambac Default” could prompt other counterparties to make 
similar assertions, which would increase the risk of losing control 
rights in other transactions.

Risk Related to Segregated Account Rehabilitation

Actions  of  the  Rehabilitator  could  adversely  affect  Ambac, 
including  impacting  our  ability  to  realize  our  remediation 
recoveries.

As  a  consequence  of  the  Segregated  Account  Rehabilitation 
Proceedings,  the  Rehabilitator  retains  operational  control  and 
decision-making authority with respect to all matters related to the 
Segregated  Account,  including  surveillance,  remediation,  loss 
mitigation and efforts to recover losses in the Segregated Account, 
including recovery efforts in respect of breaches of representations 
and warranties by sponsors of Ambac-insured RMBS. Similarly, 
by virtue of the contracts executed between Ambac Assurance and 
the Segregated Account in connection with the establishment, and 
subsequent  rehabilitation,  of  the  Segregated  Account,  the 

| Ambac Financial Group, Inc.   26   2016 FORM 10-K |

Rehabilitator retains the discretion to oversee and approve certain 
actions  taken  by  Ambac  Assurance  in  respect  of  assets  and 
liabilities  that  remain  in  Ambac  Assurance.  Moreover,  the 
Rehabilitator retains the sole discretion to adjust claim payments, 
to  make  payments  on  Deferred Amounts  and,  with  regulatory 
approval,  to  make  payments  on  or  redeem  Segregated Account 
surplus  notes  (which  would  require Ambac Assurance  to  make 
proportionate payments on or proportionately redeem its surplus 
notes).  As a result, certain efforts to remediate losses, and certain 
other  actions  taken  by  Ambac  Assurance,  are  subject  to  the 
approval of the Rehabilitator, as are decisions about the timing of 
payments of significant liabilities of the Segregated Account. In 
exercising such authority, the Rehabilitator will act for the benefit 
of policyholders, and will not take into account the interests of our 
securityholders.  Decisions  made  by  the  Rehabilitator  for  the 
benefit  of  policyholders  may  result 
in  material  adverse 
consequences for our securityholders. In addition, we are not able 
to predict the impact such decisions will have on the remediation 
of  losses,  and,  in  particular,  on  our  efforts  to  recover  losses 
attributable  to  breaches  of  representations  and  warranties  by 
sponsors  of  Ambac-insured  RMBS,  our  ability  to  commute 
outstanding policies and purchase insured bonds or surplus notes, 
or how vigorously the Rehabilitator will pursue risk remediation 
in general.  We are similarly unable to predict the decisions of the 
Rehabilitator  as  to  claims  payments  or  payments  on  Deferred 
Amounts or, with regulatory approval, payments on or redemptions 
of  Segregated Account  surplus  notes,  the  timing  and  impact  of 
which may negatively affect our financial condition or results of 
operations.    Furthermore,  any  negative  consequences  resulting 
from payments on or redemptions of Segregated Account surplus 
notes would be magnified due to the fact that the Rehabilitator’s 
decision to make such payments would, as a result of the terms of 
the  Settlement  Agreement,  dated  as  of  June 7,  2010  (the 
"Settlement  Agreement"),  by  and  among  Ambac  Assurance, 
Ambac  Credit  Products  LLC  (“ACP”),  Ambac  and  certain 
counterparties  to  credit  default  swaps  with  ACP  that  were 
guaranteed  by Ambac Assurance,  require Ambac Assurance  to 
make proportionate payments on its surplus notes.

Changes to the Segregated Account Rehabilitation Plan could 
adversely  affect  the  holders  of  securities  issued  or  insured  by 
Ambac Assurance or the Segregated Account.

The Rehabilitator retains discretion to pursue modifications to the 
Segregated Account Rehabilitation Plan, subject to the approval 
of  the  Rehabilitation  Court.  Such  modifications  could  include, 
among others, an adjustment to the rate of accretion on Deferred 
Amounts, which the Rehabilitator has stated is under review. Any 
such  changes  could  have  an  adverse  effect  on  the  interests  of 
holders, or a subset of holders, of securities issued or insured by 
Ambac Assurance or the Segregated Account.

Intercompany disputes or disputes with OCI may arise, which 
may have material adverse effects on the Company.

The  Segregated Account, Ambac Assurance, Ambac  and  other 
affiliates  have  entered  into  agreements  that  govern  certain 
activities of such entities. OCI has certain enforcement rights with 
respect to such agreements and, as regulator of Ambac Assurance 
and  as  Rehabilitator  of  the  Segregated  Account,  has  further 
authority  over  the  activities  of  Ambac  Assurance  and  the 
Segregated Account. Disputes may arise over the interpretation of 
such  agreements,  the  exercise  or  purported  exercise  of  rights 
thereunder, or the performance of or failure or purported failure to 

perform  obligations  thereunder.  Disputes  may  also  arise  over 
certain actions taken or proposed to be taken by OCI in reliance 
on its contractual or legal rights or in reaction to actions taken or 
to be taken by the Company. In taking such actions or reacting to 
actions or decisions of the Company, the Rehabilitator will act for 
the  benefit  of  policyholders,  and  will  not  take  into  account  the 
interests  of  our  securityholders.  Any  such  dispute  could  have 
material  adverse  effects  on  the  Company,  whether  through 
litigation, failure to execute transactions sought by management, 
interference with corporate strategies, objectives or prerogatives, 
inefficient  decision-making  or  execution,  forced  realignment  of 
resources, increased costs, distractions to management, strained 
working  relationships  or  otherwise.  Such  effects  would  also 
increase  the  risk  that  OCI  would  seek  to  initiate  rehabilitation 
proceedings against Ambac Assurance.

Risks Related to Capital, Liquidity and Markets

Our inability to realize the expected recoveries included in our 
financial  statements  could  adversely  impact  our  liquidity, 
financial condition and results of operations.

As of December 31, 2016, we have estimated representation and 
warranty  subrogation  recoveries  of  $1,878.7  million  (net  of 
reinsurance) included in our financial statements. These recoveries 
are based on contractual claims arising from RMBS transactions 
that  we  have  insured,  and  represent  a  probability-weighted 
estimate of amounts we expect to recover under various possible 
scenarios,  and  do  not  represent  the  best  or  the  worst  possible 
outcomes with respect to any particular transaction or group of 
transactions. Our ability to recover these amounts and the time of 
the recoveries, if any, is subject to significant uncertainty, including 
risks  inherent  in  litigation,  collectability  of  such  amounts  from 
counterparties and/or their respective parents and affiliates, timing 
of  receipt  of  any  such  recoveries,  intervention  by  OCI  or  the 
Rehabilitator which could impede our ability to take the actions 
required to realize such recoveries, and uncertainties inherent in 
the assumptions used in estimating such recoveries. The amount 
of these subrogation recoveries is significant and if we were unable 
to  recover  such  amounts,  our  stockholders’  equity  as  of 
December 31, 2016 would decrease from $1,978.0 million to $99.3 
million.

We expect to recover material amounts of claims payments through 
remediation measures including the litigation described above as 
well  as  through  cash  flows  in  the  securitization  structures  of 
transactions  that  we  insure.  Realization  of  such  expected 
recoveries is subject to various risks and uncertainties, including 
the rights and defenses of other parties with interests that conflict 
with  our  interests,  the  performance  of  the  collateral  and  assets 
backing the obligations that we insure, the performance of servicers 
involved in securitizations in which we participate as insurer, and 
the effect on our rights of the Segregated Account Rehabilitation 
Plan  and  orders  of  the  Rehabilitation  Court.  Additionally,  the 
Segregated Account Rehabilitation Proceedings may impair our 
ability to realize recoveries in insured transactions if orders of the 
Rehabilitation Court are not effective.

Adverse developments with respect to such variables may cause 
our  recoveries  to  fall  below  expectations,  which  could  have  a 
material adverse effect on our financial condition, including our 
capital and liquidity.

We may not be able to successfully monetize assets, restructure 
or exchange certain outstanding debt and insurance obligations, 
or commute or reduce insured exposures.

Ambac Assurance is evaluating the possibility of entering into one 
or more transactions to improve the financial condition of Ambac 
Assurance  which  may,  subject  to  OCI  approval,  lead  to  the 
conclusion of the Segregated Account Rehabilitation Proceedings. 
In  pursuing  this  objective, Ambac Assurance  is  considering  the 
possibility  of  monetizing  certain  assets,  restructuring  or 
exchanging  certain  outstanding  debt  and  insurance  obligations, 
and/or commuting or reducing insured exposures. Transactions of 
this nature may not be feasible or economically viable.  We cannot 
provide  any  assurance  that  any  such  transaction  will  be 
consummated by Ambac Assurance in the future, or if it is, as to 
the timing, terms or conditions of any such transaction, or as to 
whether it could lead to the conclusion of the Segregated Account 
Rehabilitation  Proceedings.    OCI  has  not  indicated  a  course  of 
action to address Segregated Account or other obligations or to 
conclude the Segregated Account Rehabilitation Proceedings.  The 
terms,  conditions,  and  timing  of  a  potential  conclusion  of  the 
Segregated Account  Rehabilitation  Proceedings  are  in  the  sole 
discretion of OCI, and subject to the approval of the Rehabilitation 
Court.  This discretion includes the authority to address Segregated 
Account obligations without the agreement of Ambac Assurance 
or its board of directors. Even if Ambac Assurance consummates 
one or more such transactions, doing so may ultimately prove to 
be unsuccessful in creating value for any or all of our stakeholders 
and may adversely affect our operating results or financial position.  
Moreover,  any  such  transaction  would  be  subject  to  the  prior 
approval of the board of directors of Ambac Assurance, OCI and 
the  Rehabilitation  Court  and  may  require  third-party  consents, 
which may not be obtained.

that 

The Rehabilitator recently filed with the Rehabilitation Court a 
supplement to his 2016 Annual Report dated June 1, 2016 relating 
to  the  Segregated  Account  Rehabilitation  Proceedings  (the 
“Supplement”). In the Supplement, the Rehabilitator stated that at  
the  present  time and absent  further  actions,  Ambac Assurance 
has  insufficient  capital  to  demonstrate to the satisfaction of the 
the  Segregated  Account  Rehabilitation 
Rehabilitator 
Proceedings could be concluded  and leave Ambac Assurance with 
sufficient financial resources to  meet all policy  obligations,  as  
projected  by  the  Rehabilitator  (in  his  sole  discretion)  under  
a    varying    range    of    base    and    stress    case    scenarios.     The 
Rehabilitator  further  stated  in  the  Supplement  that  given  such 
requirements,  any transaction facilitating the conclusion of the 
Segregated Account  Rehabilitation  Proceedings  will    need    to  
provide  for  an  increase  in  Ambac Assurance’s  existing  surplus  
capital, as determined and defined by OCI in its sole discretion. 
We  cannot  provide  assurance  that  the  terms  of  any  possible 
transaction  will  satisfy  OCI  or  the  Rehabilitator  that  Ambac 
Assurance has, or will have, sufficient capital to meet all policy 
obligations  after  the  conclusion  of  the  Segregated  Account 
Rehabilitation Proceedings. The terms, conditions, and timing of 
a potential conclusion of the Segregated Account Rehabilitation 
Proceedings are in the sole discretion of OCI, and subject to the 
approval  of  the  Rehabilitation  Court.  Even  if  the  Segregated 
Account  Rehabilitation  Proceedings  could  be  brought  to  a 
successful conclusion, there can be no assurance that any level of 
capital deemed sufficient by OCI to permit such conclusion will 
be  sufficient  to  cover  all  future  losses,  whether  currently 
anticipated or unanticipated.

Revenues and cash flow would be adversely impacted by a decline 
in realization of installment premiums.

Due  to  the  installment  nature  of  a  significant  percentage  of  its 
premium  income,  Ambac  Assurance  has  an  embedded  future 
revenue  stream.  The  amount  of  installment  premiums  actually 
realized by Ambac Assurance could be reduced in the future due 
to  factors  such  as  early  termination  of  insurance  contracts, 
accelerated prepayments of underlying obligations or insufficiency 
of cash flows (by the premium paying entity). Additionally, the 
Segregated Account Rehabilitation Proceedings may result in the 
loss of installment premium income from such insured transactions 
if  orders  of  the  Rehabilitation  Court  are  not  effective.    Such 
reductions would result in lower revenues.

The change in composition of the securities in our investment 
portfolio exposes us to greater risk.

Each  of Ambac Assurance  and Ambac Assurance  UK  Limited 
(“Ambac UK”) maintains a portion of its investment portfolio in 
lower-rated  securities  and/or  “alternative  assets”  in  order  to 
increase the risk-adjusted return on its portfolio. Investments in 
lower-rated securities and “alternative assets” could expose Ambac 
and/or Ambac UK to greater earnings volatility, increased losses 
and decreased liquidity in the investment portfolio.

We have substantial indebtedness, which could adversely affect 
our financial condition, operational flexibility and our ability to 
obtain financing in the future.

We have a substantial amount of indebtedness.  Our substantial 
level of indebtedness and other financial obligations as well as the 
performance of our insured portfolio, which is driven to an extent 
by events outside our control, increase the possibility that we may 
be unable to generate cash sufficient to pay, when due, the principal 
of, interest on, or other amounts due, in respect of our indebtedness.  
Our substantial debt and events outside our control could also have 
other significant consequences.  For example, it could:

• 

• 

• 

• 

• 

• 

• 

increase  our  vulnerability  to  general  adverse  economic, 
competitive and industry conditions;

limit our ability to obtain additional financing in the future 
for  working  capital,  capital  expenditures,  payment  of 
policyholder 
requirements, 
debt 
acquisitions, general corporate purposes or other purposes 
on satisfactory terms or at all;

claims, 

service 

require us to dedicate a substantial portion of our cash flow 
from  operations  to  the  payment  of  our  indebtedness, 
thereby reducing the funds available to us for operations 
and to fund the execution of our key strategies;

limit or restrict us from making strategic acquisitions or 
cause us to make non-strategic divestitures;

limit  our  ability  or  increase  the  costs  to  refinance 
indebtedness  or  ever  repay  such  indebtedness  due  to 
ongoing interest accretion;

limit our ability to attract and retain key employees; and

limit  our  ability  to  enter  into  hedging  transactions  by 
reducing the number of counterparties with whom we can 
enter into such transactions, as well as the volume of those 
transactions.

| Ambac Financial Group, Inc.   28   2016 FORM 10-K |

Despite current indebtedness levels, we and our subsidiaries may 
incur additional debt.  While restrictive covenants in certain of our 
contracts  currently  provide  limits  on  the  amount  of  additional 
indebtedness Ambac Assurance may incur, we may obtain a waiver 
of those restrictions and incur additional indebtedness in the future.  
In addition, if Ambac incurred indebtedness, it would depend on 
our subsidiaries to distribute funds to it so that Ambac could pay 
its obligations and expenses, including satisfying its indebtedness. 
Ambac’s ability to make scheduled payments on, or refinance, any 
such indebtedness would depend on the ability of our subsidiaries 
to made distributions or dividends, which in turn will depend on 
their  future  operating  performance  and  legal  and  regulatory 
restrictions on the payment of distributions or dividends to which 
they  may  be  subject.   There  can  be  no  assurance  that  any  such 
dividends  or  distributions  would  be  made.    This  could  further 
exacerbate the risks associated with our substantial leverage.

The  determination  of  the  amount  of  other-than  temporary 
impairments taken on our investments is highly subjective and 
could  materially  impact  our  results  of  operations  or  financial 
position.

The  determination  of  the  amount  of  impairments  on  our 
investments  varies  by  investment  type  and  is  based  upon  our 
periodic evaluation and assessment of known and inherent risks 
associated with the respective asset class. Such evaluations and 
assessments are revised as conditions change and new information 
becomes available. Management updates its evaluations regularly 
and  reflects  changes  in  impairments  as  such  evaluations  are 
revised.  There  can  be  no  assurance  that  our  management  has 
accurately assessed the level of impairments taken in our financial 
statements. Furthermore, additional impairments may need to be 
taken in the future. Historical trends may not be indicative of future 
impairments. In particular, we use externally developed financial 
models to project impairments with respect to RMBS held in our 
investment  portfolio,  including  Ambac  Assurance  guaranteed 
RMBS. Differences in the models we employ and/or flaws in these 
models  and/or  faulty  assumptions  inherent  in  these  models  and 
those  determined  by  management,  could  lead  to  increased 
impairments with respect to RMBS in our investment portfolio.

Risks Related to the Financial and Credit Markets

Changes in prevailing interest rate levels and market conditions 
could adversely impact our business results and prospects.

liquidity  needs  due 

Increases in prevailing interest rate levels can adversely affect the 
value  of  our  investment  portfolio  and,  therefore,  our  financial 
strength. In the event that investments must be sold in order to pay 
claims, to pay Deferred Amounts, to redeem surplus notes, or to 
meet  Financial  Services 
to  contract 
terminations or collateral posting requirements, such investments 
would likely be sold at discounted prices. Additionally, increasing 
interest  rates  would  have  an  adverse  impact  on  our  insured 
portfolio.  For  example,  increasing  interest  rates  could  result  in 
higher claim payments in respect of defaulted obligations that bear 
interest at floating rates of interest. Higher interest rates can also 
lead  to  increased  credit  stress  on  consumer  asset-backed 
transactions (as the securitized assets supporting a portion of these 
exposures  are  floating  rate  consumer  obligations),  slower 
prepayment speeds and resulting “extension risk” relative to such 
consumer asset-backed transactions in our insured and investment 
portfolios, and decreased refinancing activity.

Decreasing  interest  rates  could  result  in  early  terminations  of 
financial guarantee insurance policies in respect of which we are 
paid  on  an  installment  basis  and  do  not  receive  a  termination 
premium,  thus reducing premium earned for these  transactions. 
Decreases in prevailing interest rates may also limit growth of or 
reduce investment income and may adversely impact our interest 
rate swap portfolio.

Our investment portfolio may also be adversely affected by credit 
rating downgrades, ABS and RMBS prepayment speeds, foreign 
exchange movements, spread volatility, and credit losses.

We are subject to credit risk throughout our businesses, including 
large  single  risks,  risk  concentrations,  correlated  risks  and 
reinsurance counterparty credit risk.

in 

We  are  exposed  to  the  risk  that  issuers  of  debt  which  we  have 
insured  (or  with  respect  to  which  we  have  written  credit 
derivatives),  issuers  of  debt  which  we  hold  in  our  investment 
portfolio, reinsurers and other contract counterparties (including 
derivative  counterparties)  may  default 
their  financial 
obligations, whether as the result of insolvency, lack of liquidity, 
operational failure, fraud or other reasons. These credit risks could 
cause increased losses and loss reserves, and/or estimates of credit 
impairments  and  mark-to-market  losses  with  respect  to  credit 
derivatives  in  our  financial  guarantee  business;  and  we  could 
experience  losses  and  decreases  in  the  value  of  our  investment 
portfolio and, therefore, our financial strength. Such credit risks 
may  be  in  the  form  of  large  single  risk  exposures  to  particular 
issuers, reinsurers or counterparties; losses caused by catastrophic 
events (including terrorist acts and natural disasters); losses caused 
by increases in municipal defaults; or losses in respect of different, 
but correlated, credit exposures.

Risks Related to the Company's Business

We are subject to the risk of litigation and regulatory inquiries 
or investigations, and the outcome of proceedings we are or may 
become involved in could have a material adverse effect on our 
business,  operations,  financial  position,  profitability  or  cash 
flows. 

Ambac Assurance  is  defending  various  lawsuits  relating  to  its 
financial  guarantee  business.  Ambac  is  defending  a  putative 
securities class action lawsuit.  In addition, the Company from time 
to  time  receives  various  regulatory  inquiries  and  requests  for 
information. Please see Note 17. Commitments and Contingencies
to the Consolidated Financial Statements included in Part II, Item 8 
in this Form 10-K for information on these various proceedings. 

It is not possible to predict whether additional suits will be filed 
or  whether  additional  regulatory  inquiries  or  requests  for 
information will be made, and it is also not possible to predict the 
outcome of litigation, inquiries or requests for information. It is 
possible that there could be unfavorable outcomes in these or other 
proceedings. Management is unable to make a meaningful estimate 
of the amount or range of loss that could result from unfavorable 
outcomes  or  of  the  expenses  that  will  be  incurred  in  defending 
these lawsuits. Under some circumstances, adverse results in any 
such  proceedings  and/or  the  incurring  of  significant  litigation 
expenses could be material to our business, operations, financial 
position, profitability or cash flows.

The  Settlement Agreement  contains  restrictive  covenants  that 
may impair our ability to pursue our business strategies.

Pursuant  to  the  terms  of  the  Settlement  Agreement,  Ambac 
Assurance must seek prior approval by OCI of certain corporate 
actions. The Settlement Agreement also includes covenants which 
generally restrict the operations of Ambac Assurance and remain 
in force until the surplus notes that were issued to the counterparties 
by Ambac Assurance pursuant to the Settlement Agreement have 
been  redeemed,  repurchased  or  repaid  in  full.  Certain  of  these 
restrictions  may  be  waived  with  the  approval  of  a  majority  of 
Unaffiliated  Qualified  Directors  (as  defined  in  the  Settlement 
Agreement), certain holders of our surplus notes and/or OCI. If we 
are unable to obtain the required consents under the Settlement 
Agreement, we may not be able to execute our planned business 
strategies.

System security risks, data protection breaches and cyber-attacks 
could adversely affect our business and results of operations.

We  rely  on  our  information  technology  systems  for  many 
enterprise-critical functions and a prolonged failure or interruption 
of these systems for any reason could cause significant disruption 
to our operations and have a material adverse effect on our business, 
financial  condition  and  operating  results.  Our  information 
technology and application systems may be vulnerable to threats 
from  computer  viruses,  natural  disasters,  unauthorized  access, 
cyber attack and other similar disruptions. Computer hackers may 
be  able  to  penetrate  our  network’s  system  security  and 
misappropriate  or  compromise  confidential  information,  create 
system  disruptions  or  cause  shutdowns.  In  addition  to  our  own 
confidential information, we sometimes receive and are required 
to protect confidential information from third parties. To the extent 
any disruption or security breach results in a loss or damage to our 
data, or inappropriate disclosure of our confidential information 
or that of others, it could cause significant financial losses that are 
either not, or not fully, insured against, damage to our reputation, 
affect our relationships with third parties, lead to claims against 
us, result in regulatory action, or otherwise have a material adverse 
effect on our business or results of operations. In addition, we may 
be required to incur significant costs to mitigate the damage caused 
by  any  security  breach,  or  to  protect  against  future  damage. 
Moreover,  although  we  have  disaster  recovery  and  business 
continuity plans in place, we may not be able to adequately execute 
these plans in a timely fashion in the event of a disruption to our 
information technology and application systems. 

We  may  incur  losses  resulting  from  operational  risk  due  to 
inadequate or failed internal processes, breakdown of settlement 
or communication systems, or from external events leading to 
disruption  of  our  business.  Events  subject  to  operational  risk 
include:

• 

• 

• 

Internal  Fraud-misappropriation  of  assets,  intentional 
mismarking of positions 

External Fraud-theft of information, third-party theft and 
forgery 

Clients,  Products, &  Business  Practice-improper  trade, 
fiduciary breaches 

•  Damage to Physical Assets 

• 

• 

Business Disruption & System Failures-software failures, 
hardware failures; and 

Execution,  Delivery, &  Process  Management-data  entry 
errors,  accounting  errors,  failed  mandatory  reporting, 
settlement errors, and negligence.

We may be adversely affected by failures in services or products 
provided by third parties.

We  have  outsourced  and  may  continue  to  outsource  certain 
segments of our operations and business, and rely upon third-party 
vendors for other essential services and information, such as the 
provision of data used in setting loss reserves and the provision of 
risk management information and services. A material failure by 
an external service or information provider or a material defect in 
the  products,  services  or  information  provided  thereby  could 
adversely affect our financial condition and results of operations.

Our  inability  to  attract  and  retain  qualified  executives  and 
employees or the loss of any of these personnel could negatively 
impact our business.

Our ability to execute on our business strategies depend on the 
retention  and  recruitment  of  qualified  executives  and  other 
professionals.  We  rely  substantially  upon  the  services  of  our 
current executive team. In addition to these officers, we require 
key staff with risk mitigation, structured finance, insurance, credit, 
investment, accounting, finance, legal and technical skills. As a 
result  of  Ambac’s  financial  situation  and  the  rehabilitation 
proceedings for the Segregated Account, there is a higher risk that 
executive officers and other key staff will leave the Company and 
replacements may not be motivated to join the Company. The loss 
of the services of members of our senior management team or our 
inability to hire and retain other talented personnel could delay or 
prevent  us  from  succeeding  in  executing  our  strategies,  which 
could further negatively impact our business.

Our  business  could  be  negatively  affected  by  actions  of 
stakeholders whose interests may not be aligned with the broader 
interests of our stockholders.

Ambac  could  be  negatively  affected  as  a  result  of  actions  by 
stakeholders whose interests may not be aligned with the broader 
interests of our stockholders, and responding to any such actions 
could be costly and time-consuming, disrupt operations and divert 
the attention of management and employees.  Such activities could 
interfere with our ability to execute on our strategic plans.

Risks Related to International Business

Actions of the PRA and FCA could reduce the value of Ambac 
UK  realizable  by  Ambac,  which  could  adversely  affect  our 
securityholders. 

Ambac’s international business is operated by Ambac UK, which 
is regulated by the Prudential Regulation Authority (“PRA”) for 
prudential purposes and the Financial Conduct Authority (“FCA”) 
for conduct purposes. Under the Financial Services and Markets 
Act 2000 (“FSMA”), the PRA authorized Ambac UK to carry out 
financial guaranty insurance business in the UK and in the EU by 
way of the EU’s passporting regime (although this may change 
following  Brexit),  subject  to  the  terms  and  conditions  of  the 
permission  granted  by  the  PRA  and  consented  to  by  the  FCA.   
However, the terms of Ambac UK’s regulatory authority are now 
restricted and Ambac UK is in run-off.  Among other things, Ambac 
UK may not write any new business, and, with respect to any entity 

| Ambac Financial Group, Inc.   30   2016 FORM 10-K |

within the Ambac group of affiliates, commute, vary or terminate 
any existing financial guaranty policy, transfer certain assets, or 
pay dividends, without the prior approval of the PRA and FCA.  
The  PRA  and  FCA  act  generally  in  the  interests  of Ambac  UK 
policyholders  and  will  not  take  into  account  the  interests  of 
securityholders of Ambac or Ambac Assurance when considering 
  Accordingly, 
whether 
determinations made by the PRA and FCA, in their capacity as 
Ambac  UK’s  regulator,  could  potentially  result  in  adverse 
consequences for our securityholders and also reduce the value 
realizable by Ambac for Ambac UK.

to  provide  any  such  approval. 

Regulatory  uncertainty  in  relation  to  Ambac  UK’s  capital 
position could adversely affect the value of Ambac UK and affect 
our securityholders.

Under applicable regulatory capital rules (“Solvency II”) Ambac 
UK remains significantly deficient in terms of capital.  Ambac UK 
does not have a remedial plan other than to build its assets over 
time  by  on-going  premium  collections  and  earned  investment 
income,  as  well  as  attempting  to  accelerate  the  run-off  of  its 
exposures.  Further, there currently is no prospect of any capital 
support from the Ambac group of affiliates.  The PRA is well aware 
of Ambac  UK’s  position  and  prospects.  The  PRA  supervisory 
statement SS7/15 “Supervision of firms in difficulty or run-off” 
notes  that  “there  are  many  circumstances  in  which  a  run-off 
strategy is in the best interests of policyholders” and notes that the 
PRA will review such firms and that they “may be permitted to 
continue activities necessary to carry out existing contracts in a 
manner, and for so long as, the PRA considers necessary in order 
to  afford  an  appropriate  degree  of  protection  to  policyholders”.  
AUK clearly falls into this category and therefore AUK’s current 
run  off  approach  remains  at  all  times  subject  to  the  continuing 
forbearance of the PRA in relation to its capital deficit and related 
Solvency II requirements. Alternative courses of action open to the 
PRA could adversely impact the anticipated run-off trajectory of 
Ambac UK and impact its value.

Uncertainty regarding the economic impact of “Brexit” may have 
an adverse effect on Ambac’s insured international portfolio and 
the  value  of  its  foreign  investments,  both  of  which  primarily 
reside with its subsidiary Ambac UK.

In  a  non-binding  referendum  on  the  United  Kingdom’s  (“UK”) 
membership in the European Union in June 2016, a majority of 
those who voted approved the UK’s withdrawal from the European 
Union  (“EU”).  As  a  result  of  the  referendum,  the  British 
government has announced that it intends to commence negotiating 
the terms of the UK’s withdrawal from the EU (“Brexit”) and of 
its  future  relationship  with  the  EU  in  March  2017,  with  the 
expectation of withdrawing two years later. The terms of the future 
relationship between the EU and the UK are uncertain at this time 
and may be so for some time to come, and could result in the UK 
losing access to certain aspects of the single EU market and the 
global trade deals negotiated by the EU on behalf of its members. 
The Brexit vote, subsequent uncertainty, and the perceptions as to 
the ultimate impact of the withdrawal of the UK may adversely 
affect business activity, political stability and economic conditions 
in the UK, the Eurozone, the EU and elsewhere. The economic 
outlook could be further adversely affected by (i) the risk that one 
or more other EU countries could come under increasing pressure 
to leave the EU, (ii) the risk of a greater demand for independence 
by Scottish nationalists or for unification in Ireland and its impact 
on the United Kingdom, or (iii) the risk that the Euro as the single 

currency  of  the  Eurozone  could  cease  to  exist.  Any  of  these 
developments, or the perception that any of these developments 
are  likely  to  occur,  could  have  a  material  adverse  effect  on 
economic growth or business activity in the UK, the Eurozone, 
and/or the EU, and could result in the relocation of businesses, 
cause  business  interruptions,  lead  to  economic  recession  or 
depression, and impact the stability of the financial markets, the 
availability of credit, political systems or financial institutions and 
the financial and monetary system.

These economic conditions, particularly a recession or depression, 
may  have  a  material  adverse  effect  on  Ambac’s  international 
insured exposures particularly in the UK and Europe, the majority 
of which reside in Ambac UK. The creditworthiness of Ambac’s 
international insured exposures is subject to risks associated with, 
among  other  matters,  lower  asset  values  related  to  collateral 
backing transactions, depressed demand for services resulting in 
lower  operating  cash  flows  and  reduced  access  to  the  capital 
markets and other sources of financing or refinancing. In addition, 
such conditions may have a material adverse effect on the value 
and  volatility  of  investments,  including  investments  in  UK 
property funds and equities that Ambac maintains, mainly through 
Ambac  UK,  in  markets  and  currencies  outside  of  the  U.S. 
Collectively, these effects may have a negative impact on Ambac’s 
operating results and financial condition resulting from unexpected 
credit,  investment  and  foreign  exchange  losses,  volatile  asset 
values, reduced liquidity and lost revenues.

The  uncertainty  concerning  the  timing  and  terms  of  the  Brexit 
could result in additional volatility in the equity, foreign exchange, 
real  property,  bond  and  other  markets,  which  could  adversely 
impact the UK economy and Ambac's results of operations and 
financial condition over the near and long term.

Risks Related to Taxation

Certain surplus notes or other obligations issued by either Ambac 
Assurance or the Segregated Account may be characterized as 
equity of Ambac Assurance and as a result, Ambac Assurance 
may  no  longer  be  a  member  of  the  U.S.  federal  income  tax 
consolidated group of which Ambac is the common parent.

It is possible that certain surplus notes or other obligations issued 
by  either Ambac Assurance  or  the  Segregated Account  may  be 
characterized  as  equity  of  Ambac  Assurance  for  U.S.  federal 
income tax purposes. If such surplus notes or other obligations are 
characterized  as  equity  of Ambac Assurance  that  is  taken  into 
account for tax affiliation purposes and it is determined that such 
“equity” represented more than twenty percent of the total value 
of the stock of Ambac Assurance, Ambac Assurance may no longer 
be characterized as an includable corporation that is affiliated with 
Ambac.  As  a  result,  Ambac  Assurance  would  no  longer  be 
characterized  as  a  member  of  the  U.S.  federal  income  tax 
consolidated group of which Ambac is the common parent (the 
“Ambac Consolidated Group”) and Ambac Assurance would be 
required to file a separate consolidated tax return as the common 
parent  of  a  new  U.S.  federal  income  tax  consolidated  group 
including Ambac Assurance as the new common parent and Ambac 
Assurance’s  affiliated  subsidiaries  (the  “Ambac  Assurance 
Consolidated Tax Group”).

To  the  extent Ambac Assurance  is  no  longer  a  member  of  the 
Ambac  Consolidated  Group,  Ambac  Assurance’s  NOLs  (and 
certain other available tax attributes of Ambac Assurance and the 

| Ambac Financial Group, Inc.   31   2016 FORM 10-K |

other members of the Ambac Assurance Consolidated Tax Group) 
may  no  longer  be  available  for  use  by  the  Ambac  Assurance 
Consolidated Tax Group or any of the remaining members of the 
Ambac Assurance  Consolidated  Tax  Group  to  reduce  the  U.S. 
federal income tax liabilities of the Ambac Assurance Consolidated 
Tax Group. Ambac, Ambac Assurance and their affiliates entered 
into a tax sharing agreement that would require Ambac to make 
certain tax elections that could mitigate the loss of NOLs and other 
tax attributes resulting from a deconsolidation of Ambac Assurance 
from the Ambac Consolidated Group. However, in the event of a 
deconsolidation, certain other benefits resulting from U.S. federal 
income tax consolidation may no longer be available to the Ambac 
Consolidated Group including certain favorable rules relating to 
transactions  occurring  between  members  of 
the  Ambac 
Consolidated  Group  and  members  of  the  Ambac  Assurance 
Consolidated Tax Group.

If surplus notes or other obligations are characterized as equity 
of Ambac Assurance, the Ambac Assurance NOLs (and certain 
other tax attributes or tax benefits of the Ambac Consolidated 
Group) may be subject to limitation under Section 382 of the Tax 
Code.

It is possible that certain surplus notes or other obligations may be 
characterized  as  equity  of  Ambac  Assurance  for  U.S.  federal 
income  tax  purposes.  Such  characterization  could  result  in  an 
“ownership  change”  of  Ambac  Assurance  for  purposes  of 
Section 382 of the Tax Code. If such an ownership change were 
to  occur,  the  value  and  amount  of  the Ambac Assurance  NOLs 
would  be  substantially  impaired,  increasing  the  U.S.  federal 
income tax liability of Ambac Assurance and materially reducing 
the value of Ambac Assurance’s stock owned by Ambac and the 
potential of future cash tolling or dividend payments from Ambac 
Assurance to Ambac.

Deductions with respect to interest accruing on certain surplus 
notes may be eliminated or deferred until payment.

To the extent certain surplus notes are characterized as equity for 
U.S.  federal  income  tax  purposes,  accrued  interest  will  not  be 
deductible by Ambac Assurance. In addition, even if such surplus 
notes  are  characterized  as  debt  for  U.S.  federal  income  tax 
purposes, the deduction of interest accruing on such surplus notes 
may be deferred until paid or eliminated in part depending upon 
(i) the terms of any deferral and payment provisions provided in 
such  surplus  notes,  (ii) whether  such  surplus  notes  have 
“significant original issue discount,” and (iii) the yield to maturity 
of surplus notes. To the extent deductions with respect to interest 
are  eliminated  or  deferred,  the  U.S.  federal  income  tax  of  the 
members of the Ambac Consolidated Group or the members of the 
Ambac Assurance Consolidated Tax Group as the case may be, 
could be increased reducing the amount of cash available to pay 
its obligations.

Changes in Political or Economic Conditions

New  U.S.  Administration’s  proposed  tax  reform  may  have 
adverse consequences for the Company.

The recent presidential and congressional elections in the United 
States could result in significant changes in, and uncertainty with 
respect to, legislation, regulation and government policy. While it 
is not possible to predict whether and when any such changes will 
occur, changes at the local, state or federal level could significantly 
impact our business and the insurance industry.

In particular, significant changes in the U.S. federal tax code are 
possible.    One  potential  proposal  is  to  reduce  the  U.S.  federal 
corporate income tax rate to 15%.  Any reduction to the federal 
corporate income tax rate will reduce the value of Ambac’s and 
Ambac Assurance’s NOLs.  This potential loss of value includes 
the  prospects  of  lower  tolling  payments  to  be  made  by Ambac 
Assurance to Ambac.   In addition, the effects of lower corporate 
tax rates, when coupled with other economic expectations (such 
as higher inflation) may adversely impact the pricing and valuation 
of  fixed-income  securities,  including  those  in  our  investment 
portfolio.

A  reduction  in  the  U.S.  federal  corporate  tax  rates  may  also 
adversely  affect  municipal  issuers’  funding  costs  and  market 
access.      A  lower  corporate  tax  rate  could  make  tax-exempt 
indebtedness issued by municipal issuers less attractive, possibly 
resulting in a re-pricing of the municipal bond market.  Any such 
re-pricing  may  result  in  lower  re-fundings  of  our  municipal 
exposures than projected, and/or increased losses in our municipal 
credit portfolio.

In addition, there can be no certainty that the proposed tax reforms 
will  not  also  limit  or  abolish  the  income  tax  exemption  for 
municipal  bond  interest.  Such  a  reform  could  potentially  place 
further stress on municipal issuers’ ability to fund their operations, 
with the potential for increased defaults on debt service payments.

We  are  also  currently  unable  to  predict  whether  other  reform 
discussions  will  meaningfully  change  existing  legislative  and 
regulatory environments relevant for our business, or if any such 
changes  would  have  a  net  positive  or  negative  impact  on  our 
business. To the extent that such changes have a negative impact 
on us, including as a result of related uncertainty, these changes 
may  materially  and  adversely  impact  our  business,  financial 
condition, results of operations and cash flows.

Risks Related to Strategic Plan

Ambac  is  exploring  select  business  opportunities  which  may 
permit utilization of Ambac’s net operating loss carry-forwards; 
however, such business opportunities may not be consummated, 
or  if  consummated,  may  not  create  value  and  may  negatively 
impact our financial results.

Ambac  is  exploring  select  business  opportunities  which  may 
permit utilization of its net operating loss carry-forwards.  Such 
business opportunities, may involve the acquisition of assets or 
existing businesses or the development of businesses through new 
or existing subsidiaries. It is not possible at this time to predict the 
future  prospects  or  other  characteristics  of  any  such  business 
opportunities. Although we intend to conduct business, financial 
and legal due diligence in connection with the evaluation of any 
future  business  or  acquisition  opportunities,  there  can  be  no 
assurance  our  due  diligence  investigations  will  identify  every 
matter that could have a material adverse effect on us. Efforts to 
pursue  select  business  opportunities  may  be  unsuccessful  or 
require significant financial or other resources, which could have 
a negative impact on our financial condition. No assurance can be 
given  that  Ambac  will  be  able  to  complete  such  business 
opportunities,  generate  any  earnings  or  be  able  to  successfully 
integrate any such business into our current operating structure.

Moreover, Ambac’s ability to enter new businesses, including new 
businesses  apart  from  Ambac  Assurance,  is  also  subject  to 
significant  doubt,  given  the  condition  and  circumstances  of  the 

| Ambac Financial Group, Inc.   32   2016 FORM 10-K |

Segregated  Account  and  Ambac  Assurance,  the  difficulty  of 
leveraging or monetizing Ambac’s other assets, and the uncertainty 
of its ability to raise capital. Due to these factors, as well as those 
relating to Ambac Assurance as described in this Item 1A. Risk 
Factors, the value of our securities is highly speculative.

Ambac’s current strategy and initiatives have been derived from, 
and created as a consequence of, the company’s current financial 
condition  and  circumstances.  Should  changes  in  Ambac’s 
circumstances or financial condition or in the political, economic 
and/or legal environment occur, there can be no assurances that all 
or any part of such strategy and/or initiatives will not be abandoned 
or amended to take account of such changes. Any such adjustment 
or abandonment may have an adverse effect on our securities.

Stock Performance Graph

The following graph compares the performance of an investment in our common stock from the close of business on May 1, 2013, the date 
we emerged from bankruptcy through December 31, 2016, with the Russell 2000 Index, S&P 500 Financials Index and S&P Completion 
Index. The S&P Completion Index has been added in 2016 since it includes other Financial Guaranty companies and similarly sized companies 
to Ambac, as measured by market capitalization.  The graph assumes $100 was invested on May 1, 2013 in our common Stock at the closing 
price of $20 per share and at the closing price for the Russell 2000 Index, S&P 500 Financials Index and S&P Completion Index. It also 
assumes that dividends (if any) were reinvested on the date of payment without payment of any commissions. The performance shown in the 
graph represents past performance and should not be considered an indication of future performance.

Selected Financial Data

The following financial information for the five years ended December 31, 2016, has been derived from Ambac’s Consolidated Financial 
Statements.  Following the Company’s emergence from bankruptcy on May 1, 2013, the consolidated financial statements reflect the application 
of fresh start reporting (“Fresh Start”), incorporating, among other things, the discharge of debt obligations, issuance of new common stock 
and fair value adjustments. The effects of the reorganization and Fresh Start adjustments are recorded in Predecessor Ambac’s Consolidated 
Statement of Total Comprehensive Income for the period ended April 30, 2013. The financial results of the Company for the periods from 
May 1, 2013 are referred to as “Successor” and the financial results for the periods through April 30, 2013 are referred to as “Predecessor”. 
The 2013 Successor Period and the 2013 Predecessor Period are distinct reporting periods.  As a result of the implementation of Fresh Start, 
results and balances are not comparable between Successor Ambac and Predecessor Ambac. This information should be read in conjunction 
with the Consolidated Financial Statements and related notes located in Part II, Item 8 in this Form 10-K.

Item 7.   Management’s Discussion and Analysis of Financial Condition and Results of Operations

This Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) contains certain financial measures, 
in particular the presentation of Adjusted Earnings and Adjusted Book Value, which are not presented in accordance with accounting principles 
generally accepted in the United States (“GAAP”). We are presenting these non-GAAP financial measures because they provide greater 
transparency and enhanced visibility into the underlying drivers of our business. We do not intend for these non-GAAP financial measures to 
be a substitute for any GAAP financial measures and they may differ from similar reporting provided by other companies. Readers of this 
Form 10-K should use these non-GAAP financial measures only in conjunction with the comparable GAAP financial measures. Adjusted 
Earnings  and Adjusted Book Value are non-GAAP financial measures that adjust for the impact of certain non-recurring or non-economic 
GAAP accounting requirements and include the addition of certain items that the Company has or expects to realize in the future, but that are 
not reported under GAAP. We also provide reconciliations to the most directly comparable GAAP measures; Adjusted Earnings to Net income 
attributable to common stockholders and Adjusted Book Value to Total Ambac Financial Group, Inc. stockholders’ equity.

EXECUTIVE SUMMARY

Asset Management:

Ambac Assurance and subsidiaries:

A key strategy for Ambac is to increase the value of its investment 
in Ambac Assurance by actively managing its assets and liabilities.  
Asset management primarily entails maximizing the risk adjusted 
return on non-VIE invested assets and managing liquidity to help 
ensure resources are available to meet operational and strategic 
cash needs.  These strategic cash needs include activities associated 

Investment portfolios are subject to internal investment guidelines, 
including limits on types and quality of investments imposed by 
applicable insurance laws and regulations. As part of its investment 
strategy, and in accordance with the aforementioned guidelines, 
Ambac Assurance and Ambac Assurance UK Limited ("Ambac 
UK") purchase distressed Ambac-insured securities based on their 
risk/reward  characteristics.  During  2016,  Ambac 
relative 

| Ambac Financial Group, Inc.   36   2016 FORM 10-K |

(inclusive of its subsidiaries) acquired $658.5 million of distressed 
Ambac-insured  securities,  including  $494.4  million  of  insured 
RMBS and $128.1 million of insured student loan securities with 
policies allocated to the Segregated Account and $36.0 of other 
insured  securities.  Future  cash  flows  relating  to  those  invested 
assets  allocated  to  the  Segregated Account  include  the  sum  of 
(i) the  bond’s  intrinsic  cash  flows  and  (ii) the  estimated Ambac 
Assurance  claim  payments,  including  Deferred  Amounts  (as 
defined in the Segregated Account Rehabilitation Plan).  At the 
end of 2016, Ambac owned approximately $1.5 billion, or 41% of 
the total Deferred Amounts outstanding. Ambac will continue to 
  The 
opportunistically  purchase  Ambac-insured  securities. 
investment portfolios of Ambac Assurance and Ambac UK also 
hold fixed income securities and funds that include a variety of 
other assets including, but not limited to, corporate bonds, asset 
backed  and  mortgage  backed  securities,  municipal  bonds,  high 
yield bonds, leveraged loans, equities, real estate and hedge funds.  
Refer  to  Note  10.  Investments  to  the  Consolidated  Financial 
Statements, included in Part II, Item 8 in this Form 10-K for further 
details of investments by asset class.

Liability and Insured Exposure Management:

Ambac  Assurance's  Risk  Management    Group  focuses  on  the 
analysis,  implementation  and  execution  of  commutation  and 
related  claims  reduction  or  defeasance  strategies.  Analysts 
evaluate  the  estimated  timing  and  severity  of  projected  policy 
claims  as  well  as  the  potential  impact  of  loss  mitigation  or 
remediation strategies in order to target and prioritize policies, or 
portions  thereof,  for  commutation,  refinancing  or  other  claims 
reduction or defeasance strategies. For targeted policies, analysts 
will  engage  with  bondholders,  issuers  and  other  economic 
stakeholders to negotiate, structure and execute such strategies. 

During 2016, Ambac recognized improvements in the performance 
of certain Ambac insured RMBS transactions.  Ambac reached the 
following settlements: (i) $995 million received in January 2016 
in connection with a representation and warranty settlement with 
JP Morgan; and (ii) future estimated recoveries  valued at $51.6 
million ($51.4 million net of reinsurance) at December 31, 2016 
in connection with a settlement outside of litigation and unrelated 
to  Ambac's  R&W  subrogation  recoveries.  Separately,  Ambac 
Assurance  received  $100.3  million  ($99.1  million  net  of 
reinsurance)  of  subrogation  recoveries  related  to  an  omnibus 
settlement with investors in Countrywide securitizations, that was 
announced in June 2011 by Bank of New York Mellon, as Trustee, 
whereby  Bank  of  America  agreed  to  pay  $8.5  billion  across 
approximately  530  RMBS 
trusts  (“Countrywide  Investor 
Settlement”).  The Countrywide Investor Settlement was included 
in previous loss reserve estimates as other subrogation.

During 2016, Ambac Assurance purchased $9.6 million of unpaid 
accrued  interest  related  to  certain  surplus  notes  that  were 
previously repurchased under call options.  Ambac recognized a 
realized gain on these purchases of $3.1 million in the Consolidated 
Statements of Total Comprehensive Income.  In addition, Ambac 
Assurance  purchased  $18.6  million  of  its  surplus  notes  during 
2016. Ambac recognized realized gains on these purchases of $1.7 
million in the Consolidated Statements of Total Comprehensive 
Income.

The following table provides a comparison of both total and below 
investment  grade  ("BIG")  net  par  outstanding    in  the  insured 
portfolio at December 31, 2016 and 2015.  Net par exposures within 

the U.S. public finance market include capital appreciation bonds 
which are reported at the par amount at the time of issuance of the 
insurance policy.

The overall reduction in total net par outstanding resulted from 
scheduled maturities, amortizations, refundings, refinancings and 
calls accelerated by several company-led initiatives, including an 
overall $935 million reduction of student loan net par exposure, 
including  commutations  of  $387  million  net  par  of  National 
Collegiate  Student  Loan  Trust  bonds;  and  the  $458  million 
cancellation of net par exposure to Local Insight Media ("LIM").

The reduction in below investment grade net par outstanding was 
primarily due to (i) the aforementioned commutations of student 
loan  policies,  (ii)  reductions  to  residential  mortgage-backed 
securities during the year as a result of both prepayments by issuers 
the 
and  claims  presented 
aforementioned cancellation of the LIM insured bonds.

Although our insured portfolio has performed satisfactorily over 
the  course  of  2016,  we  have  experienced  stress  within  our 
approximately $2.1 billion of exposures to Puerto Rico consisting 
of several different issuing entities (all below investment grade). 
Each issuing entity has its own credit risk profile attributable to 
discreet  revenue  sources,  direct  general  obligation  pledges  and 
general obligation guarantees.  Refer to Part I, Item 1 in this Form

Ambac: 

As of December 31, 2016 total cash and investments of Ambac 
were $342.8 million, which include the following:

• 

• 

• 

• 

Liquid  investments  in  asset  backed  and  short-term 
securities of $212.1 million 

Investments in Ambac-insured securities with a fair value

value of $14.3 million, which is eliminated in consolidation

Residual interest in a VIE Trust that was created in 2014 
to monetize Ambac's ownership interest in junior surplus 
notes issued by the Segregated Account.  Ambac's carrying 
value, utilizing the equity method, of this investment was 
$30.0  million  at  December 31,  2016.    Refer  to  Note  3. 
Special  Purpose  Entities,  Including  Variable  Interest 
Entities to the Consolidated Financial Statements included 
in Part II, Item 8 in this Form 10-K, for more information 
on this transaction.

During  2015,  the  Board  of  Directors  of Ambac  authorized  the 
establishment of a warrant repurchase program that permits the 
repurchase of up to $10 million of warrants. On November 3, 2016, 
the  Board  of  Directors  of Ambac  authorized  an  additional  $10
million to the warrant repurchase program. As of December 31, 
2016, Ambac had repurchased 985,331 warrants at a cost of $8.1 
million,  leaving  4,053,670  warrants  outstanding,  bringing  the 

| Ambac Financial Group, Inc.   37   2016 FORM 10-K |

remaining aggregate authorization to $11.9 million. Ambac will 
opportunistically consider additional purchases in the future.

As a result of positive taxable income at Ambac Assurance in 2015, 
Ambac received $70.9 million in tax tolling payments in May 2016 
and $0.5 million in November 2016. Additionally, based on Ambac 
Assurance's 2016 taxable income, Ambac is expected to receive 
approximately $28.7 million in tax tolling payments by June 2017 
(subject to Rehabilitator review).

Foreign Currency Impacts:

The strengthening of the U.S. dollar since the Brexit referendum 
vote  impacted  Ambac's  economic  position.    Specifically,  the 
impact of using March 31, 2016 currency rates against the current 
balance sheet, excluding VIEs, provides for an approximate loss 
of $68 million, as follows:

•

•

•

A reduction of investments and loan values held in British
Pounds and Euros of approximately $37.2 million.  As of
December 31, 2016 Ambac held British Pound and Euro
loans and investments of £171.2 million and €23.5 million,
respectively.  All but £3.4 million of these amounts were
held  by Ambac  UK.    Included  within  the  British  Pound
portfolio is £27.0 million invested in a UK property fund.

Since the referendum vote, there have been reduced 
valuations of commercial real estate and a number 
of  such  funds  suspended  redemptions.  The  UK 
property fund that Ambac UK has invested in has 
not suspended redemptions as of this date.

A reduction in premiums receivable denominated in British
Pounds and Euros of $32.5 million.  As of December 31,
2016 premium receivables in British Pounds totaled £144.4
million and Euros totaled €33.1 million.

A decrease in the carrying value of loss reserves related to
policies where loss payments will be made in currencies
other  than  the  US  dollar  of  $1.7  million.    As  of
December 31,  2016,  loss  and  loss  expense  reserves  for
British Pounds totaled zero and Euros totaled €20.3 million.

Financial Statement Impacts:

The  impact  of  foreign  currency  as  reported  in  Ambac's 
Consolidated Statement of Total Comprehensive Income for the 
year ended December 31, 2016 included the following:

Future changes to currency rates may adversely affect our financial 
results.  Refer to Part II, Item 7A "Quantitative and Qualitative 
Disclosures  about  Market  Risk"  for  further  information  on  the 
impact  of  future  currency  rate  changes  on  Ambac's  financial 
instruments.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Ambac's Consolidated Financial Statements have been prepared 
in  accordance  with  GAAP.    This  section  highlights  accounting 
estimates  management  views  as  critical  because  they  require 
management to make difficult and subjective judgments regarding 
matters that are inherently uncertain and subject to change. These 
estimates are evaluated on an on-going basis based on historical 
developments,  market  conditions,  industry  trends  and  other 
information that is reasonable under the circumstances. There can 
be no assurance that actual results will conform to estimates and 
that reported results of operations will not be materially adversely 
affected  by  the  need  to  make  future  accounting  adjustments  to 
reflect changes in these estimates from time to time.

Management  has  identified  the  following  critical  accounting 
policies  and  estimates:  (i) valuation  of  loss  and  loss  expense 
reserves, (ii) valuation of financial instruments and (iii) valuation 
of deferred tax assets. Management has discussed each of these 
critical  accounting  policies  and  estimates  with  the  Audit 
Committee, including the reasons why they are considered critical, 
and  how  current  and  anticipated  future  events  impact  those 
determinations. Additional information about these policies can be 
found in Note 2. Basis of Presentation and Significant Accounting 
Policies to the Consolidated Financial Statements included in Part 
II, Item 8 in this Form 10-K. 

Valuation of Losses and Loss Expense Reserves:

The loss and loss expense reserves ("loss reserves") discussed in 
this  section  relate  only  to  Ambac’s  non-derivative  financial 
guarantee business for insurance policies issued to beneficiaries, 
including unconsolidated VIEs. Ambac's loss reserves include loss 
reserve  components  of  an  insurance  policy,  including  unpaid 
claims and the present value ("PV") of expected net cash flows 
required to be paid under an insurance contract. Unpaid claims, 
which include accrued interest, represent claims that have not yet 
been paid for policies allocated to the Segregated Account. The 
PV of expected net cash flows represents the PV of expected cash 
outflows less the PV of expected cash inflows discounted at a risk-
free discount rate.  While unpaid claims are known and therefore 
not a subjective estimate, expected future losses, net of expected 
future recoveries, are inherently uncertain. As such, the remaining 
discussion is limited to addressing expected future losses, net of 
expected future recoveries.

The  evaluation  process  for  expected  future  losses  is  subject  to 
certain  estimates  and  judgments  regarding  the  probability  of 
default  by  the  issuer  of  the  insured  security,  probability  of 
remediation  and    settlement  outcomes  (which  may  include 
commutation,  litigation  settlements,  refinancings  and/or  other 
settlement  outcomes),  probability  of  a  restructuring  outcome 
(which may include payment moratoriums, debt haircuts and/or 
subsequent recoveries) and the expected loss severity of credits for 
each insurance contract.

As the probability of default for an individual credit increases and/
or the severity of loss given a default increases, our loss reserve 

| Ambac Financial Group, Inc.   38   2016 FORM 10-K |

for that insured obligation will also increase. Political, economic, 
credit or other unforeseen events could have an adverse impact on 
default probabilities and loss severities. The loss reserves for many 
transactions  are  derived  from  the  issuer’s  creditworthiness.  For 
public  finance  issuers,  loss  reserves  will  consider  not  only 
creditworthiness but also political dynamics and economic status 
and prospects. The loss reserves for other transactions which have 
no direct issuer support, such as most structured finance exposures, 
including RMBS and student loan exposures, are derived from the 
default  activity  and  loss  given  default  of  underlying  collateral 
supporting the transactions. In addition, many transactions have a 
combination of issuer/entity and collateral support. Loss reserves 
reflect our assessment of the transaction’s overall structure, support 
and expected performance. Loss reserve volatility will be a direct 
result of the credit performance of our insured portfolio, including 

the number, size, bond types and quality of credits included in our 
loss reserves as well as our ability to execute workout strategies 
and commutations. The number and severity of credits included in 
our loss reserves depend to a large extent on transaction specific 
attributes, but will generally increase during periods of economic 
stress  and  decline  during  periods  of  economic  prosperity. 
Reinsurance contracts mitigate our loss reserve.   Since Ambac has 
little exposure ceded to reinsurers, it is unlikely to have a significant 
effect on loss reserve volatility. Loss reserve volatility will also be 
materially impacted by changes in interest rate projections from 
period to period.

The table below indicates the gross par outstanding and gross loss 
reserves (including loss expenses) related to policies in Ambac’s

$847 and $44, respectively at December 31, 2015. Ceded loss and loss expense reserves are included in Reinsurance recoverable on paid and unpaid 
losses. 

(2)  Loss and Loss Expense reserves at December 31, 2016 of $3,696 are included in the balance sheet in the following line items: Loss and loss expense 
reserves: $4,381 and Subrogation recoverable: $685. Loss and Loss Expense reserves at December 31, 2015 of $2,859 are included in the balance sheet 
in the following line items: Loss and loss expense reserves: $4,088 and Subrogation recoverable: $1,229. 

(3) 

Included in Gross Loss and Loss Expense Reserves are unpaid claims of $3,656 and $3,459 at December 31, 2016 and 2015, respectively, related to 
policies allocated to the Segregated Account, inclusive of accrued interest payable on Deferred Amounts of $662 and $491, respectively. 

(4)  Ambac records as a component of its loss and loss expense reserves, estimated recoveries related to securitized loans in RMBS transactions that breached 
certain representations and warranties.  Ambac has recorded gross estimated recoveries of $1,907 and $2,830 at December 31, 2016 and 2015, respectively.

See  Note  2.  Basis  of  Presentation  and  Significant  Accounting 
Policies  for  a  description  of  the  cash  flow  and  statistical 
methodologies used to develop loss reserves.   Most of our reserved 
credits  with  large  loss  reserves  utilize  the  cash  flow  method  of 
reserving.    Alternative  cash  flow  scenarios  are  developed  to 
represent  the  range  of  possible  outcomes  and  resultant  future 
claims  payments  and  timing.    Scenarios  and  probabilities  are 
adjusted  regularly  to  reflect  changes  in  status,  outlook  and  our 
analysis and views.  Significant judgment is used to develop the 
cash  flow  assumptions,  and  there  can  be  no  certainty  that  the 
modeled scenarios or probabilities will not deviate materially from 
ultimate outcomes.  

In  some  cases,  such  as  RMBS  and  student  loans,  which  are 
described  more  fully  below,  cash  flow  projections  include  the 
modeling of an issuer or transaction’s future revenues and expenses 
to  determine  the  resources  available  to  pay  debt  service  on  our 
insured obligations.  In other cases, such as many public finance 
exposures  including  our  Puerto  Rico  exposures,  we  do  not 
specifically forecast resources available to pay debt service in the 
cash flow model itself.  Rather, we consider the issuers’ overall 
ability and willingness to pay, including the fiscal, economic, legal 

and  political  framework.    We  then  develop  multiple  scenarios 
where issuer debt service is paid, missed and/or haircut with claims 
paid then modeled for any recovery amount and timing.  In our 
experience, this has been an effective approach to loss reserving 
these types of credits, but there is no certainty our assumptions as 
to scenarios or probabilities will not be subject to material changes 
as developments occur or that this method will be as effective in 
the future as it has been in the past.

In estimating loss reserves, we also incorporate scenarios which 
represent  remediation  strategies.  Remediation  scenarios  may 
include the following; (i) a potential refinancing of the transaction 
by  the  issuer;  (ii) the  issuer’s  ability  to  redeem  outstanding 
securities at a discount, thereby increasing the structure’s ability 
to  absorb  future  losses;  and  (iii) our  ability  to  terminate  or 
restructure the policy in whole or in part (e.g., commutation). The 
remediation scenarios and the related probabilities of occurrence 
vary by policy depending on on-going and expected discussions 
and negotiations that are underway with issuers and/or investors. 
In addition to commutation negotiations that are underway with 
various counterparties in various forms, our reserve estimates may 
also  include  scenarios  which  incorporate  our  ability  and/or

to  commute  additional  exposure  with  other 

model assumptions, improvements to modeling capabilities and 
approaches and other factors. 

RMBS Expected Loss Estimate

Second-Lien Model: 

Ambac  insures  RMBS  transactions  collateralized  by  first-lien 
mortgages. Ambac classifies its insured first-lien RMBS exposure 
principally into two broad credit risk classes: mid-prime (including 
Alt-A,  interest  only,  and  negative  amortization)  and  sub-prime. 
Mid-prime loans were typically made to borrowers who had credit 
profiles  stronger  than  sub-prime  loans,  but  weaker  than  prime 
loans. Compared with mid-prime loans, sub-prime loans typically 
had higher loan-to-value ratios, reflecting the greater difficulty that 
sub-prime  borrowers  have  in  making  down  payments  and  the 
propensity of these borrowers to extract equity during refinancing. 

Ambac  has  also  insured  RMBS  transactions  collateralized 
predominantly by second-lien mortgage loans such as closed-end 
seconds and home equity lines of credit. A second-lien mortgage 
loan is a type of loan in which the borrower uses the equity in their 
home as collateral and the second-lien loan is subordinate to the 
first-lien loan outstanding on the home. Borrowers are obligated 
to make monthly payments on both their first and second-lien loans. 
If the borrower defaults on the payments due under these loans and 
the property is subsequently liquidated, the liquidation proceeds 
are first utilized to pay off the first-lien loan (as well as other costs) 
and any remaining funds are applied to pay off the second-lien 
loan. As a result of this subordinate position to the first-lien loan, 
second-lien loans carry a significantly higher severity in the event 
of a loss, approaching or exceeding 100%. 

Ambac  primarily  utilizes  a  statistically  based  cash  flow  model 
(“RMBS  cash  flow  model”)  to  develop  estimates  of  projected 
losses for both our first and second lien transactions. The RMBS 
cash flow model projects collateral performance utilizing: (i) the 
loans'  characteristics  and  status, 
transaction’s  underlying 
(ii) projected home price appreciation (“HPA”) and (iii) projected 
interest rates. We source HPA projections from a market accepted 
vendor  and interest rate projections are developed from market 
sources. We generally utilize waterfall projections from a market 
accepted  vendor  which  models  securitization  deal  structures. In 
some cases, we may utilize an alternative waterfall structure when 
our legal and commercial analysis of the transaction’s payment 
structure differs from the vendor’s waterfall structure. 

We  compare  monthly  claims  submitted  against  the  trustees’ 
reports, 
third-party  provided  waterfall  models  and  our 
understanding of the transactions’ structures to identify and resolve 
discrepancies.  We  also  systematically  review  the  vendor’s 
published  waterfall  revisions 
identify  material 
discrepancies.  Resolving  discrepancies  is  challenging  and  may 
take place over an extended period of time. Moreover, transaction 
documents are subject to interpretation, and our interpretation or 
that of the vendor and as reflected in our loss reserves may prove 
to be incorrect and/or not consistent with trustees directing cash 
flows in the future. 

to  further 

In our experience, market performance and model characteristics 
change  and  are  updated  through  time  and  a  regular  review  of 
current models, alternative models and the overall approach to loss 
estimation is beneficial. The RMBS cash flow model is subject to 
ongoing refinements and/or replacement resulting from industry 
research as well as performance analysis that may better inform 

The RMBS cash flow model estimates mortgage loan collateral 
performance, the effect of such collateral cash flows within the 
transaction  waterfall  and  the  liability  structure  we  insure. 
Collateral  performance  is  frequently  modeled  at  the  deal  level 
given  the  paucity  of  mortgage  loan  level  data  for  second-lien 
transactions. In the absence of specific loan-level information, the 
deal-level approach evaluates a loan pool as if it were a single loan, 
selecting  certain  aggregated  deal-level  characteristics  to  then 
perform  a  series  of    statistical  analyses.  We  use  three  HPA 
projection scenarios to develop a base case as well as stress and 
upside cases. The highest probability is assigned to the base case, 
with lower probabilities to the stress and upside cases. This deal-
level  approach  takes  relatively  complicated  monthly  collateral 
performance and divides it into two parts: a borrower-behavior-
dependent stage and a servicer-behavior-dependent stage. 

The borrower-behavior-dependent stage is designed to forecast the 
probability of a loan’s present delinquency status transitioning to 
any  of  eight  future  statuses.  The  deal-level  approach  projects 
performance using a roll-rate that evaluates the possible future state 
of a loan based on its current status and three variables: average 
FICO (credit score), average current consolidated loan to value 
ratio  (“CLTV”)  and  an  overall  quality  indicator.  The  servicer-
behavior-dependent stage governs a loan’s life cycle after it reaches 
180 or more days delinquent. This stage evaluates the servicer’s 
propensity  to  foreclose  or  pursue  a  short  sale,  the  speed  of  the 
foreclosure  process,  and  the  speed  of  the  post-foreclosure 
distressed  property  liquidation.  The  transition  probabilities 
between stages are assumed by the model to depend upon how 
long a loan has already been in a particular status, as well as on 
the servicer-specific and state-specific liquidation timeline factors. 

First-Lien Model: 

For most first-lien transactions, the RMBS cash flow model utilizes 
mortgage  loan  level  data  from  recognized  market  sources  to 
calculate  probability  of  default  and  prepayment  based  on  loan 
characteristics. The loan-level approach of the RMBS cash flow 
model uses results of a regression analysis to project prepayment 
and default vectors on a monthly basis. For first-lien transactions 
that do not have loan-level data available, we use the deal-level 
approach of the model that is described in the Second-Lien section 
above. 

There are three general stages with the loan-level approach of the 
model:  current,  prepayment  or  default.  The  model  then  looks 
beyond the stages to assess a set of loans based on a number of 
individual characteristics that are distinct to that set of loans. The 
model  will  project  performance  based  on  the  borrower’s  given 
probability  of  transitioning  that  month.  Servicer  behavior  is  a 
variable  in  the  loan-level  approach;  computing  the  impact  of 
servicing on the associated collateral. Consistent with the second-
lien modeling, we consider three HPA scenarios in the RMBS cash 
flow model to develop a base case as well as stress and upside 
cases. The highest probability is assigned to the base case, with 
lower probabilities to the stress and upside cases.

Other RMBS Factors: 

Additional factors that may impact ultimate RMBS second-lien 
and first-lien losses include, but may not be limited to, mortgage 
insurance, servicer intervention and third-party settlements. 

Mortgage  insurance:  Five  of  our  mortgage-backed  transactions 
have  pool-level  mortgage  insurance  remaining.  Pool  mortgage 
insurance is a master policy issued to the mortgage securitization 
trust, which indemnifies the trust either on a first loss or mezzanine 
basis in the event that covered mortgage loans in the trust default. 
The mortgage insurance master policy includes various conditions 
such as exclusions, conditions for notification of loans in default 
and  claims  settlement.  We  have  noted  with  regard  to  these 
transactions that payment by mortgage insurers of claims presented 
by the mortgage trusts has been inconsistent, resulting in higher 
claims  presented  under Ambac Assurance’s  financial  guarantee 
policies. Additionally, much of the mortgage insurance coverage 
has been exhausted.  As a result, the benefit of mortgage insurance 
on our loss reserve estimate is negligible. 

Servicer Intervention: We include in our modeling the steps which 
Ambac is taking to address shortcomings in servicing performance. 
Ambac  has  initiated  programs  with  selected  servicers  that  we 
believe  will  mitigate  losses  on  such  transactions  through 
intervention  strategies  such  as  loan  modifications,  improved 
liquidation timelines and short sales. Ambac believes these are the 
principal controllable factors that will result in reduced losses over 
time. Given the uncertainty in initiating additional programs of this 
nature, we give credit in our models only on exposures that have 
already  transferred  servicing  or  entered  into  special  servicing 
agreements. 

Third  party  settlements:  To  the  extent  that  we  are  aware  of 
settlements between issuers and investors or trustees which may 
provide for recoveries within certain insured RMBS trusts, we have 
incorporated in our modeling of collateral losses our estimate of 
the  probable  amount  and  timing  of  these  settlements.    As  of 
December  31,  2016,  we  are  not  aware  of  any  undistributed 
settlements between issuers and investors or trustees which may 
provide for future recoveries within our insured RMBS trusts.

Expected Representation and Warranty Subrogation Recoveries 

Ambac  records  as  a  component  of  its  loss  reserve  estimate, 
subrogation  recoveries  related  to  securitized  loans  in  RMBS 
transactions that breached certain representations and warranties 
("R&W") described herein. Generally, the sponsor of an RMBS 
transaction provided representations and warranties with respect 
to the securitized loans, including representations with respect to 
the  loan  characteristics,  the  absence  of  borrower  fraud  in  the 
underlying  loan  pools  or  other  misconduct  in  the  origination 
process and attesting to the compliance of loans with the prevailing 
underwriting policies.  In such cases, the sponsor of the transaction 
is  contractually  obligated  to  repurchase,  cure  or  substitute 
collateral  for  any  loan  that  breaches  the  representations  or 
warranties 

The  RMBS  R&W  subrogation  recovery  estimate  is  subject  to 
significant  uncertainty,  including  risks  inherent  in  litigation, 
collectability  of  such  amounts  from  counterparties  and/or  their 
respective  parents  and  affiliates,  timing  of  receipt  of  any  such 
recoveries, intervention by OCI which could impede our ability to 
take actions required to realize such recoveries and uncertainties 
inherent  in  the  assumptions  used  in  estimating  such  recoveries.    

Refer to Note 2. Basis of Presentation and Significant Accounting 
Policies and Note 7. Financial Guarantee Insurance Contracts to 
the Consolidated Financial Statements included in Part II, Item 8 
in this Form 10-K for more information regarding the estimation 
process for representation and warranty subrogation recoveries. 

Student Loan Expected Loss Estimate 

The significant majority of our student loan portfolio consists of 
credits collateralized by private student loans, with a small portion 
collateralized  by federally  guaranteed  loans  under  the  Federal 
Family Education Loan Program (“FFELP”). 

The  calculation  of  loss  reserves  for  our  student  loan  portfolio 
involves  evaluating  numerous  factors  that  can  impact  ultimate 
losses.  The  factor  which  contributes  the  greatest  degree  of 
uncertainty  in  ascertaining  appropriate  loss  reserves  is  the  long  
final legal maturity date of the insured bonds. Most of the student 
loan bonds which we insure were issued with original terms of 20 
to  40  years  until  final  maturity.  Since  our  policy  covers  timely 
interest and ultimate principal payment, our loss projections must 
make assumptions for many factors covering a long time horizon. 
Key assumptions that will impact ultimate losses include, but are 
not  limited  to,  the  following:  collateral  performance  (which  is 
highly  correlated  to  the  economic  environment),  interest  rates, 
operating  risks  associated  with 
issuer,  servicers  and 
administrators,  investor  appetite  for  tendering  or  commuting 
insured  obligations  and,  as  applicable,  Ambac’s  ability  and 
willingness to commute policies. 

the 

In evaluating our student loan portfolio, our losses are projected 
using  a  cash  flow  approach.  In  order  to  project  collateral 
performance under the cash flow approach, we use an internally 
developed default projection tool that constructs lifetime cohort 
default curves based on loan and deal-level historical performance 
data.  To determine ultimate losses on the transactions, the cohort 
default  curves  are  used  to  extrapolate  future  default  behavior.  
Additionally,  a  regression-based  model  is  used  to  estimate 
recoveries  on  defaulted  loans.    This  regression-based  recovery 
forecast is grounded in deal-level performance data.  Losses for a 
portion  of  deals  are  forecast  using  internal  loss  estimations  to 
project transaction-level assumptions such as defaults, recoveries 
and  prepayments  based  on  analysis  of  historical  experience 
adjusted for current economic conditions and changes to collateral 
composition since origination.  In both approaches where collateral 
performance is projected, the transaction losses are incorporated 
into a third party waterfall model to develop loss estimates for our 
exposures. This waterfall model allows us to capture the impact of 
each transaction’s specific structure (e.g., the waterfall priority of 
payments, triggers, redemption priority) to generate our specific 
projected  claims  profile  in  various  base,  upside  and  downside 
scenarios. 

We develop and assign probabilities to multiple cash flow scenarios 
based on each transaction’s unique characteristics. Probabilities 
assigned  are  based  on  available  data  related  to  the  credit, 
information from contact with the issuer (if applicable), and any 
economic or market information that may impact the outcomes of 
the  various  scenarios  being  evaluated.  Our  base  case  usually 
projects  deal  performance  out  to  maturity  using  expected  loss 
assumptions. As  appropriate,  we  also  develop  other  cases  that 
incorporate  various  upside  and  downside  scenarios  that  may 
include changes to defaults and recoveries.

Variability of Expected Losses and Recoveries

Ambac’s  management  believes  that  the  estimated  future  loss 
component of loss reserves are adequate to cover future claims 
presented, but there can be no assurance that the ultimate liability 
will not be higher than such estimates. 

It  is  possible  that  our  estimated  future  loss  assumptions  for 
insurance policies discussed above could be understated. We have 
attempted to identify reasonably possible cash flows using more 
stressful  assumptions  than  the  probability-weighted  outcome 
recorded.  The  reasonably  possible  net  cash  flows  consider  the 
highest stress scenario that was utilized in the development of our 
probability-weighted  expected  loss  at  December 31,  2016  and 
assumes an inability to execute any commutation transactions with 
issuers and/or investors. Such stress scenarios are developed based 
on management’s view about all possible outcomes.  In arriving 
at such view, management makes considerable judgments about 
the possibility of various future events.  Although we do not believe 
it is reasonably possible to have worst case outcomes in all cases, 
it is reasonably possible we could have worst case outcomes in 
some or even many cases.

RMBS Variability:

Changes  to  assumptions  that  could  make  our  reserves  under-
estimated  include  an  increase  in  interest  rates,  deterioration  in 
housing prices, poor servicing, the effect of a weakened economy 
characterized by growing unemployment and wage pressures, and/
or illiquidity of the mortgage market. We utilize a complex model 
to project losses in our RMBS exposures and changes to reserves, 
either upward or downward are not unlikely if we used a different 
model  or  methodology  to  project  losses.  We  regularly  assess 
models and methodologies and may change our approaches and/
or model.  Additionally, our R&W actual subrogation recoveries 
could be significantly lower than our estimate of $1,907 million 
as  of  December 31,  2016  if  the  sponsors  of  these  transactions: 
(i) fail to honor their obligations to repurchase the mortgage loans, 
(ii) successfully dispute our breach findings, (iii) no longer have 
the  financial  means  to  fully  satisfy  their  obligations  under  the 
transaction documents, or (iv) our pursuit of recoveries is otherwise 
unsuccessful. 

In the case of both first and second-lien exposures, the reasonably 
possible stress case assumes a lower housing price appreciation 
projection,  which  in  turn  drives  higher  defaults  and  severities. 
Using  this  approach,  the  reasonably  possible  increase  in  loss 
reserves  for  RMBS  credits  for  which  we  have  an  estimate  of 
expected loss at December 31, 2016 could be approximately $78 
million.    Combined  with  the  absence  of  any  R&W  subrogation 
recoveries, a possible increase in loss reserves for RMBS could be 
approximately $1,985 million.

Public Finance Variability:

It is possible our loss reserves for public finance credits may be 
under-estimated if issuers are faced with prolonged exposure to 
adverse  political,  economic,  fiscal  or  socioeconomic  events  or 
trends. 

Our experience with the city of Detroit in its bankruptcy proceeding 
was not favorable and renders future outcomes with other public 
finance issuers even more difficult to predict and may increase the 
risk that we may suffer losses that could be sizable.  We agreed to 
settlements regarding our insured Detroit general obligation bonds 

that provide better treatment of our exposures than the city planned 
to include in its plan, but nevertheless required us to incur a loss 
for a significant portion of our exposure.  An additional troubling 
precedent  in  the  Detroit  case,  as  well  as  other  municipal 
bankruptcies,  is  the  preferential  treatment  of  certain  creditor 
classes, especially the public pensions.  The cost of pensions and 
the need to address frequently sizable unfunded or underfunded 
pensions is often a key driver of stress for many municipalities and 
their  related  authorities,  including  entities  to  whom  we  have 
significant exposure, such as Chicago, its school district, the State 
of New Jersey and many others.  Less severe treatment of pension 
obligations  in  bankruptcy  may  lead  to  worse  outcomes  for 
traditional debt creditors.  In addition, cities may be more inclined 
to use bankruptcy to resolve their financial stresses if they believe 
preferred outcomes for various creditor groups can be achieved. 

We currently consider high severity outcomes to be outlying and 
therefore  generally  assign  low  or  remote  probabilities  to  such 
outcomes in our current loss reserves unless the situation develops 
adversely.    We  expect  municipal  bankruptcies  and  defaults  to 
continue to be challenging to project given the unique political, 
governance and policy differences among municipalities as well 
as the complexity, long duration and relative infrequency of the 
cases themselves in forums with a scarcity of legal precedent.

Another potentially adverse development that could cause the loss 
reserves  on  our  public  finance  credits  to  be  underestimated  is 
deterioration in the municipal bond market that deprives issuers 
of  access  to  funding  necessary  to  avoid  defaulting  on  their 
obligations. While  our  loss  reserves  consider  our  judgment 
regarding issuers’ financial flexibility to adapt to adverse markets, 
they may not adequately capture sudden, unexpected or protracted 
market volatility that adversely affects market conditions.

Our  exposures  to  the  Commonwealth  of  Puerto  Rico  are  under 
stress arising from the Commonwealth’s poor financial condition, 
weak  economy  and  loss  of  capital  markets  access.    The 
Commonwealth has indicated it cannot afford to pay its debts and 
has announced plans to improve its financial position and prospects 
including the restructuring of debt obligations. 

Since  April  2016,  the  Commonwealth  has  been  subject  to  an 
emergency  moratorium, known as "Law 21", on debt payments 
of the Commonwealth and its instrumentalities. Beginning in April 
2016, and culminating on June 30, 2016, former Governor Padilla 
issued additional executive orders under Law 21 declaring states 
of emergency at HTA, PRIFA, PRCCDA, and other Puerto Rico 
instrumentalities  through  January  31,  2017,  and  suspending 
payment obligations on bonds issued by those entities, including 
the 
insured  by  Ambac  Assurance.  Subsequent 
bonds 
implementation of the moratorium, the Commonwealth defaulted 
on approximately $0.9 billion out of $2.0 billion of debt service 
due on July 1, 2016, including certain Puerto Rico bonds insured 
by Ambac Assurance.  On  January  29,  2017,  current  Governor 
Rosello signed the Financial Emergency and Fiscal Responsibility 
Act, which extends the emergency moratorium period until May 
1, 2017, with an option to extend another three months until August 
1, 2017. 

to 

In June 2016, the United States enacted the Puerto Rico Oversight, 
Management, and Economic Stability Act ("PROMESA"), which 
provides for, among other things, a framework for consensually 
negotiated    modifications  of  Puerto  Rico  obligations  ("Title VI 

| Ambac Financial Group, Inc.   42   2016 FORM 10-K |

Creditor Collective Action") and, if this and other measures do not 
succeed, non-consensual debt adjustments ("Title III Adjustments 
of Debt") .  In addition, while PROMESA provides that laws such 
as Law 21 are not binding on any non-consenting creditor to the 
extent  they  prohibit  the  payment  of  principal  and  interest,  the 
practical effect of this provision is unknown and Ambac is at risk 
to the ongoing execution, interpretation and ultimate enforcement 
of this provision.  PROMESA also provides for a temporary stay 
on  litigation,  which  may  delay  any  judicial  determination 
regarding  the  application  of  this  provision.   The  litigation  stay, 
which was set to expire on February 15, 2017, has been extended 
now to May 1, 2017.

As a result of the distressed situation in Puerto Rico coupled with 
the aforementioned payment moratorium on debt payments of the 
Commonwealth  and  certain  provisions  under  PROMESA,  the 
potential for a restructuring of debt insured by Ambac Assurance, 
either with or without our consent, and the possibility of protracted 
litigation as a result of which our rights may be materially impaired, 
losses  may  exceed  current  reserves  in  a  material  manner.  The 
possible outcomes could shift quickly and materially in an adverse 
manner as this volatile situation continues to develop.

For public finance credits, including Puerto Rico as well as other 
issuers,  for  which  we  have  an  estimate  of  expected  loss  at 
December 31,  2016,  the  reasonably  possible  increase  in  loss 
reserves could be approximately $1,143 million. 

Student Loan Variability:

Changes  to  assumptions  that  could  make  our  reserves  under-
estimated include, but are not limited to, increases in interest rates, 
default rates and loss severities on the collateral due to economic 
or  other  factors. For  student  loan  credits  for  which  we  have  an 
estimate of expected loss at December 31, 2016, the reasonably 
possible  increase  in  loss  reserves  could  be  approximately  $175 
million. 

Other Credits, including Ambac UK, Variability:

It is possible our loss reserves on other types of credits, including 
those insured by Ambac UK, may be under-estimated because of 
various risks that vary widely, including the risk that we may not 
be  able  to  recover  or  mitigate  losses  through  our  remediation 
processes  such  as  litigation,  depending  upon  the  nature  of  the 
exposure. For all other credits, including Ambac UK, for which 
we have an expected loss, the sum of all the highest stress case loss 
scenarios is $376 million greater than the current loss reserve at 
December 31, 2016.

Valuation of Financial Instruments:

instruments 

that  are  reported  on 

Ambac’s  financial 
the 
Consolidated Balance Sheets at fair value and subject to valuation 
estimates include investments in fixed income securities, equity 
interests in pooled investment funds, VIE loan assets, VIE long-
term debt and derivative instruments.   

The Fair Value Measurement Topic of the ASC requires reporting  
entities to maximize the use of observable inputs and minimize the 
use of unobservable inputs when measuring fair value. This Topic 
also  requires  financial  instruments  be  classified  within  a  three-
level fair value hierarchy. The fair value hierarchy, the financial 
instruments classified within each level, our valuation methods, 
inputs, assumptions and  the  review  and  validation  procedures 

over quoted and modeled pricing are further detailed in  Note 9. 
Fair  Value  Measurements 
the  Consolidated  Financial 
to 
Statements included in Part II, Item 8 in this Form 10-K.  

The level of judgment in estimating fair value is largely dependent 
on the amount of observable market information available to fair 
value a financial instrument, which is also determinative of where 
the financial instrument is classified in the fair value hierarchy.  
Instruments valued using models which use one or more significant 
inputs  or  value  drivers  that  are  unobservable  and  are  therefore 
classified as Level 3 of the fair value hierarchy, require greater 
judgment than for those instruments classified as Level 1 and 2.  
Level 3 financial instruments reported on the Consolidated Balance 
Sheets  at  fair  value  include,  but  are  not  limited  to,  credit 
derivatives,  certain  interest  rate  swaps,  investments  in  certain 
Ambac-insured fixed income securities, and certain VIE assets and 
financial 
liabilities.  Model-derived  valuations  of  certain 
instruments incorporate estimates of the effects of Ambac's own 
credit risk and/or counterparty credit risk, which  can be complex 
and judgmental.  In addition, internal valuation models for certain 
highly structured instruments, such as credit default swaps, require 
assumptions about markets in which there has been a negligible 
amount of trading activity for several years. 

As a result of these factors, the actual trade value of a financial 
instrument in the market, or exit value of a financial instrument 
owned by Ambac, may be significantly different from its recorded 
fair value. 

Impairment Evaluation of Fixed Income Securities 

In  addition  to  valuation  estimates  described  above,  another 
estimate requiring significant judgment relates to the evaluation 
for other-than-temporary impairments ("OTTI") for fixed income 
securities  (excluding VIE  investments)  classified  as  “available-
for-sale”.  Securities which have experienced declines in fair value 
below Ambac's amortized cost must be evaluated for OTTI. An 
OTTI charge is recognized if management assesses it either (i) has 
the intent to sell the security or (ii) more likely than not will be 
required to sell the security before the anticipated recovery of its 
amortized  cost  basis  less  any  current  period  credit  loss.  This 
impairment  assessment  also  involves  determining  whether  an 
actual credit loss exists for the security.

The OTTI evaluation of securities is a quantitative and qualitative 
process, which is subject to risks and uncertainties and is intended 
to determine whether, and to what extent, declines in the fair value 
of investments should be recognized in current period earnings. 
The risks and uncertainties include changes in general economic 
conditions, the issuer’s or guarantor’s financial condition and/or 
future prospects, the impact of regulatory actions on the investment 
portfolio, the performance of the underlying collateral, the effects 
of  changes  in  interest  rates  or  credit  spreads  and  the  expected 
recovery  period.  With  respect  to  all  Ambac  insured  securities 
owned,  future  cash  flows  used  to  measure  credit  impairment 
represents the sum of (i) the bond’s intrinsic cash flows and (ii) the 
estimated Ambac Assurance or Ambac U.K. claim payments. For 
Ambac-insured  securities  owned  and  guaranteed  under  policies 
allocated  to  the  Segregated  Account  ("Segregated  Account 
securities"),  the  estimate  of Ambac Assurance  claim  payments 
includes  interest  on  Deferred  Amounts.  Ambac  estimates  the 
timing of claim payment receipts on all Ambac-insured securities 
owned,  but  the  actual  timing  of  such  amounts  for  Segregated 
Account securities are at the sole discretion of the Rehabilitator.

Plan or to the rules and guidelines promulgated thereunder, orders 
from the Rehabilitation Court or actions by the Rehabilitator with 
respect  to  the  form,  amount  and  timing  of  satisfying  permitted 
policy  claims,  or  making  payments  on  Deferred  Amounts  or 
surplus  notes,  may  have  a  material  effect  on  the  fair  value  of 
Segregated Account  securities  and  future  recognition  of  OTTI.

There is also significant judgment in determining whether Ambac 
intends to sell securities or will continue to have the ability to hold 
temporarily impaired securities until recovery. Future events could 
occur that were not reasonably foreseen at the time management 
rendered its judgment on the Company’s intent to sell or ability to 
hold securities until recovery. Examples of such events include, 
but are not limited to, the deterioration in the issuer’s or guarantor’s 
creditworthiness,  a  change 
in  regulatory  requirements  or 
modifications to the Segregated Account Rehabilitation Plan or to 
the rules and guidelines promulgated thereunder, orders from the 
Rehabilitation Court or actions by the Rehabilitator with respect 
to  the  form,  amount  and  timing  of  satisfying  permitted  policy 
claims, or making payments on Deferred Amounts or surplus notes. 
If management’s judgment with respect to these factors changes, 
Ambac may ultimately record a charge for OTTI in future periods. 

Valuation of Deferred Tax Assets:

Our provision for taxes is based on our income, statutory tax rates 
and tax planning opportunities available to us in the jurisdictions 

in which we operate. Tax laws are complex and subject to different 
interpretations by the taxpayer and respective governmental taxing 
authorities. Significant judgment is required in determining our 
tax expense and in evaluating our tax positions. We review our tax 
positions  quarterly  and  adjust  the  balances  as  new  information 
becomes available. Deferred tax assets arise because of temporary 
differences between the financial reporting and tax bases of assets 
and liabilities, as well as from net operating loss ("NOL") and tax 
credit  carry  forwards.  More  specifically,  deferred  tax  assets 
represent a future tax benefit (or receivable) that results from losses 
recorded under GAAP in a current period which are only deductible 
for tax purposes in future periods and NOL carry forwards.

The NOL carryforward component of the deferred tax asset will 
expire if not utilized within certain periods. Valuation allowances 
are established to reduce deferred tax assets  to an amount that 
“more likely than not” will be realized. All available evidence, both 
positive  and  negative,  needs  to  be  identified  and  considered  in 
making  the  determination  with  significant  weight  given  to 
evidence that can be objectively verified.  The level of deferred 
tax asset recognition is influenced by management’s assessment 
of future expected taxable income, which depends on the existence 
of sufficient taxable income of the appropriate character (ordinary 
vs. capital) within the carry forward periods available under the 
tax law.  As a result of the risks and uncertainties associated with 
future operating results, management believes it is more likely than 
not that the Company will not generate sufficient taxable income 
to recover the deferred tax asset and therefore has a full valuation 
allowance. See Note 15. Income Taxes for additional information 
on the Company's deferred income taxes.

The  following  paragraphs  describe  the  consolidated  results  of 
operations of Ambac and subsidiaries for 2016, 2015 and 2014 and 
its financial condition as of December 31, 2016 and 2015.

Net Premiums Earned.  Net premiums earned primarily represent 
the amortization into income of collected insurance premiums. Net 
premiums earned for the year ended December 31, 2016 decreased 
by $115.3 million or 36.9% as compared to net premiums earned 

| Ambac Financial Group, Inc.   44   2016 FORM 10-K |

for the year ended December 31, 2015.  Net premiums earned for 
the year ended December 31, 2015 increased by $66.2 million or 
26.9% as compared to net premiums earned for the year ended 
December 31, 2014.  

We  present  accelerated  premiums,  which  result  from  calls  and 
other accelerations of insured obligations separate from normal net 
premiums  earned. When  an  insured  bond  has  been  retired,  any 
remaining unearned premium revenue ("UPR") is recognized at 
that time to the extent the financial guarantee contract is legally 
extinguished,  causing  accelerated  premium 
revenue.  For 
installment premium paying transactions, we offset the recognition 
of any remaining UPR by the reduction of the related premium 
receivable  to  zero  (as  it  will  not  be  collected  as  a  result  of  the 
retirement),  which  may  cause  negative  accelerated  premium 
revenue.    Included  within  accelerated  premiums,  were  negative 
accelerations of $7.6 million, $5.1 million, and $47.4 million, for 
the years ended December 31, 2016, 2015 and 2014, respectively.

Normal net premiums earned are impacted by the following:

• 

• 

• 

• 

The  runoff  of  the  insured  portfolio  occurring  through 
transaction  terminations,  calls  and  scheduled  maturities, 
which had a negative impact.  

in 

Changes 
the  collectability  of  certain  premium 
receivables,  primarily  within  Structured  Finance.  These 
changes resulted in an increase in net premiums earned of 
$0.8 million, $0.5 million and $2.2 million for the years 
ended December 31, 2016, 2015 and 2014, respectively.

Pre-refundings  of  insured  securities,  primarily  Public 
Finance  transactions.    Since  the  maturity  date  of  pre-
refunded  securities  is  shortened  (to  a  specified  call  date 
from  its  previous  legal  maturity),  normal  net  premiums 
earned  will  increase  over  the  remaining  period  of  the 
related policy. 

The strengthening or weakening of the U.S. dollar relative 
to  the  British  Pound  since Ambac's  wholly-owned  UK 
subsidiary, Ambac UK, operates in the United Kingdom 
and the British Pound is its functional currency.

Normal  net  premiums  earned  and  accelerated  premiums  are 
reconciled to total net premiums earned in the table below and are 
included in the Financial Guarantee segment. The following table

Included  in  Financial  Guarantee  net  investment  income  are  net 
mark-to-market  gains  of  $27.7  million,  $12.6  million  and  $6.7 
million in years ended 2016, 2015 and 2014, respectively, arising 
from  pooled  fund  investments  that  are  classified  as  trading 
securities with changes in market value recognized in earnings.  
Ambac Assurance has invested in high-yield loan funds beginning 
in 2015 as part of its overall portfolio allocation strategy.  Ambac 
UK's pooled fund investments consist of diversified asset classes 
including equities, hedge funds, loans, CLOs and property. 

Financial  Guarantee  net  investment  income    increased  $43.5 
million for the year ended December 31, 2016 compared to 2015, 
due to growth in the size of the portfolio and higher average returns. 
The larger portfolio primarily resulted from the receipt of $995 
million in January 2016 in connection with a representation and 
warranty  settlement  with  JP  Morgan.    Higher  average  portfolio 
returns in 2016 reflect higher allocations to Ambac insured RMBS, 
other securities guaranteed by Ambac Assurance or Ambac UK 
and pooled funds.  Net investment income from pooled funds in 
2016 increased $15.0 million from the prior year, due primarily to 
new investments in high-yield loan funds which performed well 
during the year and stronger returns in equity markets and asset 
backed strategies, partially offset by lower gains from property and 
hedge funds. 

The  decrease  in  Financial  Guarantee  net  investment  income  of 
$41.4 million for the year ended December 31, 2015 compared to 
2014 reflects a lower asset base, partially offset by a higher average 
rate  of  return  on  the  portfolio.   The  lower  asset  levels  in  2015 
resulted from sales and maturities of select securities to fund the 
partial  redemption  of  surplus  notes  in  November  2014  and  the 
equalizing  payment  of  Deferred  Amounts  of  the  Segregated 
Account in December 2014.  The higher average rate of return on 
the portfolio in 2015 resulted from higher allocations to Ambac 
insured  securities,  corporate  bonds  and,  in  the  Ambac  UK 
portfolio,  pooled  funds  consisting  of  diversified  asset  classes 
including equities, loans, hedge funds and property. Ambac UK 
pooled  fund  investments  experienced  higher  overall  returns  in 
2015 primarily as a result of improved hedge fund performance 
and property value increases.  The increase in income from higher 
allocation to Ambac insured securities was partially offset by the 
impact of positive performance on certain of these bonds in 2014 
and  the  adverse  impact  of  the  amended  Segregated  Account 
Rehabilitation  Plan  on  projected  cash  flows.    Refer  to  Note  1. 
Background  and  Business  Description  to  the  Consolidated 
Financial Statements, included in Part II, Item 8 in this Form 10-
K for further discussion of the partial surplus note redemptions of 
Ambac Assurance and the Segregated Account and the equalizing 
payments of Deferred Amounts.    

Financial Services investment income increased in 2016 compared 
to 2015 due to the impact of higher rates on floating rate securities. 

| Ambac Financial Group, Inc.   45   2016 FORM 10-K |

The  investment  portfolio  continues  to  decrease  as  investment 
agreements runoff. The decrease in income in 2015 compared to 
2014 reflects the smaller size of the portfolio.  

Corporate  investment  income  relates  to  Ambac’s  investment 
portfolio.   Higher investment income for the year ended December 
31,  2016  compared  to  2015  resulted  from  a  larger  portfolio 
allocation to Ambac Assurance insured RMBS and a larger asset 
base  as  Ambac  received  tax  tolling  payments  from  Ambac 
Assurance in April 2016. Investment income for the year ended 
December  31,  2015  increased  over  2014  as  a  result  of  the 
investment  of  proceeds  from Ambac's August  2014  sale  of  its 
Segregated Account junior surplus note and the yield associated 
with the related equity interest in unconsolidated subsidiaries. 

Net Other-Than-Temporary Impairment Losses.  Net other-than-
temporary  impairment  losses  recorded  in  earnings  include  only 
credit  related  impairment  amounts  on  securities  to  the  extent 
management does not intend to sell and it is not more likely than 
not that the Company will be required to sell before recovery of 
the amortized cost basis. Non-credit related impairment amounts 
are recorded in other comprehensive income. Alternatively, non-
credit related impairment is reported through earnings as part of 
net  other-than-temporary  impairment  losses  if  management 
intends  to  sell  securities  or  it  is  more  likely  than  not  that  the 
Company will be required to sell before recovery of amortized cost 
less any current period credit impairment.

Ambac's  other-than-temporary  impairments  for  the  years  ended 
December 31,  2016,  2015  and  2014  related  to  credit  losses  on 
certain Ambac-wrapped securities stemming primarily from cash 
flow timing and to the company’s intent to sell certain securities

that  were  in  an  unrealized  loss  position  as  of  the  impairment 
evaluation dates. 

Since commencement of the Segregated Account Rehabilitation 
Proceedings, changes in the estimated timing of claim payments 
have resulted in adverse changes in projected cash flows on certain 
impaired Ambac-wrapped securities. Ambac estimates the timing 
of  such  claim  payment  receipts,  but  the  actual  timing  of  such 
payments are at the sole discretion of the Rehabilitator.  Further 
modifications to the Segregated Account Rehabilitation Plan or to 
the rules and guidelines promulgated thereunder, orders from the 
Rehabilitation Court or actions by the Rehabilitator with respect 
to  the  form,  amount  and  timing  of  satisfying  permitted  policy 
claims, or making payments on Deferred Amounts or surplus notes, 
may have a material effect on the fair value of Ambac-wrapped 
securities  and  future  recognition  of  other-than-temporary 
impairments.    Refer  to  Note  1.  Background  and  Business 
Description  to  the  Consolidated  Financial  Statements  for 
information  relating 
the  amended  Segregated  Account 
Rehabilitation Plan. Ambac’s assessment about whether a decline 
in  value  is  other-than-temporary  reflects  management’s  current 
judgment regarding facts and circumstances specific to a security 
and the factors noted above, including Ambac's intention to sell 
securities and ability to hold temporarily impaired securities until 
recovery. If that judgment changes, Ambac may ultimately record 
a charge for other-than-temporary impairment in future periods.

Net  gains  during  the  year  ended  December 31,  2016  included 
foreign exchange related gains of $22.7 million on short-term and 
trading  securities  held  by Ambac  UK  and  denominated  in  non-
functional currencies (primarily US dollars and euros) and $8.3 
million  of  realized  currency  gains  related  to  available-for-sale 
securities that were sold by Ambac UK during the year.   Net gains 
during year ended December 31, 2015 arose primarily from the 
sale of Ambac insured student loan securities in connection with 
a financial guarantee commutation transaction.  Net gains during 
the year ended December 31, 2014 arose primarily from the sale 

of assets received pursuant to Ambac's remediation activities and 
net gains on securities sold in connection with the reallocation of 
the investment portfolio and to raise liquidity for the anticipated 
payment  of  Deferred Amounts  and  surplus  notes  in  the  fourth 
quarter of 2014.   

Change in Fair Value of Credit Derivatives.  The valuation of 
credit  derivative  liabilities  is  impacted  by  the  market’s  view  of 
Ambac Assurance’s credit quality. We reflect Ambac’s own credit 
quality in the fair value of such liabilities by including a credit 

| Ambac Financial Group, Inc.   46   2016 FORM 10-K |

valuation adjustment (“CVA”) in the determination of fair value.  
The gain from change in fair value of credit derivatives for the year 
ended December 31, 2016 was $20.1 million, as compared to the 
gain of  $41.7 million for the year ended December 31, 2015.  The 
gain for 2016 reflects increased pricing levels and a stronger credit 
assessment  on  an  adversely  classified  credit  in  the  portfolio, 
partially offset by the impact of lower Ambac CVA discount rates.  
The gain for 2015 was primarily due to the reversal of unrealized 
losses on adversely classified student loan credit default swaps in 
connection  with  termination  of  the  contracts  in  addition  to  the 
positive impacts of other portfolio runoff, currency exchange rates 
and  higher Ambac  CVA  discount  rates.    The  net  gain  in  2014 
resulted  from  gains  from  runoff  and  reference  obligation  price 
improvements, partially offset by declining Ambac CVA discount 
rates, especially in the first half of the year.

Realized gains and other settlements on credit derivative contracts 
represent  premiums  received  and  accrued  on  such  contracts.  
Realized  gains  and  other  settlements  were  $0.9  million,  $2.8 
million and $3.0 million for 2016, 2015 and 2014, respectively.  
The  declines  over  time  are  due  to  reduced  premium  receipts 
resulting from continued runoff of the credit derivative portfolio.   
Included  in  realized  gains  and  other  settlements  on  credit 
derivatives  were  fees  received  in  connection  with  transaction 
terminations of $0.0 million, $1.3 million and $0.5 million for the 
years 2016, 2015 and 2014, respectively.  There were no loss or 
settlement payments in the periods presented.  Unrealized gains 
(losses) on credit derivative contract reflect the impact of all other 
factors  on  the  overall  change  in  fair  value  of  credit  derivatives 
noted above. 

See Note 9. Fair Value Measurements to the Consolidated Financial 
Statements included in Part II, Item 8 in this Form 10-K for a further 
description of Ambac’s methodology for determining the fair value 
of  credit  derivatives.  The  table  below  indicates  the  impact  of 
incorporating Ambac’s own credit risk into the fair value of credit 
derivatives as of December 31, 2016 and 2015:

Derivative Product Revenues. The derivative products portfolio 
is positioned to benefit from rising rates as an economic hedge 
against interest rate exposure throughout the Company, including 
the  financial  guarantee  portfolio.    Results  in  derivative  product 
revenues  reflect  mark-to-market  (losses)  gains  in  the  portfolio 
caused by (declines) increases in forward interest rates during the 
periods,  the  carrying  cost  of  the  net  liability  position  of  the 
portfolio,  and  the  impact  of  the Ambac  CVA  and  counterparty 
credit  adjustments  as  discussed  below.    Net  losses  reported  in 
derivative product revenues for the year ended December 31, 2016 
were $50.3 million, reflecting a decline of $7.8 million as compared 
to the net losses of $42.5 million for the year ended December 31, 
2015.  The derivative product loss for 2016 was primarily driven 
by the impact lower credit spreads that reduced the Ambac CVA 
on  derivative  liabilities  and  the  carrying  cost  of  the  portfolio.  
Despite  substantial  interest  rate  movements  within  2016,  the 
overall change in rates from the beginning to the end of the year 
did not have a significant impact on full year results.

Net losses reported in the derivative product revenues for the year 
ended December 31, 2015 were $42.5 million, an improvement of 
$138.6 million as compared to net losses of $181.1 million for the 
year ended December 31, 2014. Results for both periods reflect 
mark-to-market losses caused by declines in forward interest rates, 
net  of  the  impact  of  the  Ambac  CVA  as  discussed  below.  
Additionally, counterparty credit valuation adjustments on certain 
interest  rate  swap  assets  increased  the  overall  mark-to-market 
losses for the year ended December 31, 2015.

The  fair  value  of  derivative  liabilities  includes  a  valuation 
adjustment to reflect Ambac’s own credit risk. Within the financial 
services  derivatives  portfolio,  an  Ambac  CVA  is  generally 
applicable for uncollateralized derivative liabilities that may not 
be offset by derivative assets under a master netting agreement. 
Inclusion of an Ambac CVA in the valuation of financial services 
derivatives  resulted  in  gains  (losses)  within  derivative  products 
revenues of  $(33.8) million, $14.2 million and $16.1 million, for 
the years ended December 31, 2016, 2015, and 2014, respectively.  
The impact of changes to the CVA reflects the market’s view of 
Ambac Assurance’s  credit  quality  estimated  based  on  relevant 
market data points, as well as the amount of underlying liabilities, 
which  generally  decline  as  interest  rates  increase.  Market  data 
indicated  that  the  market's  view  of  Ambac  Assurance's  credit 
quality generally improved in 2016, declined in 2015 and improved 
in 2014.  The table below indicates the impact of incorporating 
Ambac’s  own  credit  risk  into  the  fair  value  of  the  derivative 
products portfolio (excluding credit derivatives) as of December 
31, 2016 and 2015:

Net  Realized  Gains  (Losses)  on  Extinguishment  of  Debt.  Net 
realized gains on extinguishment of debt was $4.8 million for the 
year ended December 31, 2016, compared to net gains (losses) of 
$0.1 million and $(74.7) million for the years ended December 31, 
2015 and 2014, respectively.   The net gains for the year ended 
December 31, 2016 included gains from the settlement of certain 
residual obligations related to previously called surplus notes and 
settlements  of  repurchased  surplus  notes  below  their  carrying 
values. The gains for the year ended December 31, 2015 included 
gains from the settlement of certain residual obligations related to 
previously  called  surplus  notes,  partially  offset  by  losses  from 
settlement of an investment agreement above its carrying value 
and  the  accelerated  recognition  of  the  unamortized  discount  on 
surplus notes purchased during the year.

As described in Note 1. Background and Business Description to 
the Consolidated Financial Statements included in Part II, Item 8 
in this Form 10-K, the Rehabilitator redeemed certain Segregated 
Account  surplus  notes  (excluding  junior  surplus  notes)  on 
November 20, 2014 at a redemption price that included an amount 
equal to principal and accrued interest on such redeemed surplus 
notes.    Such  redemption  also  triggered  similar  proportionate 
redemption payments on Ambac Assurance's surplus notes. The 
redemption of surplus notes resulted in a charge representing the 
accelerated  recognition  of  the  unamortized  discount  on  the 
redeemed surplus notes, which amounted to $74.7 million.

Foreign exchange gains/(losses) are unrelated to investments or 
loss reserves but include gains/(losses) relating to foreign currency 
changes on present value of premium receivables denominated in 
a  subsidiary's  non-functional  currency,  in  addition  to  foreign 
exchange gains/(losses) on cash.  Other includes various financial 
guarantee  segment  fees,  primarily  consent  and  waiver  fees.  
Additionally,  in  2016,  other  includes  insurance  recoveries  on  a 
partially cancelled asset-backed transaction which is consolidated 
as a VIE, interest recoveries related to previously paid legal fees 
related to a disputed premium receivable partially offset by a loss 
mitigation  payment  on  an  international  investor-owned  utility 
transaction which is consolidated as a VIE.

Income  (loss)  on  Variable  Interest  Entities.  Included  within 
Income (loss) on variable interest entities are income statement 
amounts  relating  to VIEs  consolidated  under  the  Consolidation 
Topic of the ASC as a result of Ambac's variable interest arising 
from  financial  guarantees  written  by  Ambac's  subsidiaries, 
including  gains  or  losses  attributable  to  consolidating  or 
deconsolidating such VIEs during the periods reported.  Generally, 
the Company’s consolidated VIEs are entities for which Ambac 
has provided financial guarantees on its assets or liabilities.  In 
consolidation, most assets and liabilities of the VIEs are reported 
at  fair  value  and  the  related  insurance  assets  and  liabilities  are 
eliminated. However, the amount of VIE net assets (liabilities) that 
remain  in  consolidation  generally  result  from  the  net  positive 
(negative) present value of projected cash flows from (to) the VIEs 
which  are  attributable  to Ambac’s  insurance  subsidiaries  in  the 
form of financial guarantee insurance premiums, fees and losses. 
In the case of VIEs with net negative projected cash flows, the net 
liability  is  generally  to  be  funded  by  Ambac’s  insurance 
subsidiaries  through  insurance  claim  payments.  Differences 
between the net carrying value of the insurance accounts under the 
Financial Services—Insurance Topic of the ASC and the carrying 
value of the consolidated VIE’s net assets or liabilities are recorded 
through income at the time of consolidation or deconsolidation.  
The portion of Income (loss) on variable interest entities arising 
from the impact of consolidating and deconsolidating  VIEs was 
$0.0 million, $0.6 million, and $0.0 million for the years ended 
December 31, 2016, 2015 and 2014, respectively. 

Income  (loss)  on  variable  interest  entities  was  $(14.1)  million, 
$31.6 million and $(32.2) million for the years ended December 
31, 2016, 2015 and 2014, respectively. Income (loss) on variable 
interest entities for all three years reflected an increase (decrease) 
in the fair value of net assets primarily due to the increase (decrease) 
in  the  CVA  applied  to  certain  VIE  note  liabilities  that  include 
significant projected financial guarantee claims.   Other than those 
transactions  involving  significant  projected  financial  guarantee 
claims,  the fair value of VIE net assets increased producing net 
gains in 2016, 2015 and 2014. Refer to Note 3. Special Purpose 
Entities, Including Variable Interest Entities to the Consolidated 
Financial Statements included in Part II, Item 8 in this Form 10-
K for further information on the accounting for VIEs.

Losses and Loss Expenses.  Losses and loss expenses are based 
upon  estimates  of  the  aggregate  losses  inherent  in  the  non-
derivative  financial  guarantee  portfolio  for  insurance  policies 
issued  to  beneficiaries,  including  unconsolidated VIEs.    Losses 
and loss expenses include interest on Deferred Amounts pursuant 
to  the  amended  Segregated Account  Rehabilitation  Plan,  which 
became  effective  June  12,  2014.    The  amendments  to  the 
Segregated Account  Rehabilitation  Plan  primarily  modified  the 
mechanism for handling Segregated Account claims. Instead of 
the  combination  of  cash  payments  and  interest-bearing  surplus 
notes  originally  contemplated  by  the  Segregated  Account 
Rehabilitation  Plan,  holders  of  permitted  policy  claims  have 
received  and  will  receive  an  initial  interim  cash  payment  for  a 
portion of such policy claim (“Interim Payment”), together with 
the right to receive a deferred payment equal to the balance of the 
unpaid  policy  claim  (“Deferred  Amount”).  The  amended 
Segregated Account  Rehabilitation  Plan  requires  that  Deferred 
Amounts  generally  accrue  and  compound  interest  at  an  annual 
effective rate of 5.1%.  Losses and loss expenses for the year ended 
December 31, 2014 include interest accruals from the beginning 
of the accrual periods through December 31, 2014.

Ambac  records  as  a  component  of  its  loss  reserve  estimate, 
subrogation  recoveries  related  to  securitized  loans  in  RMBS 
transactions with respect to which Ambac Assurance is pursuing 
claims for breaches of representations and warranties described 
herein. Ambac  does  not  include  potential  recoveries  attributed 
solely  to  fraudulent  inducement  claims  in  our  litigations  in  our 
estimate of  subrogation recoveries. Generally, the sponsor of an 
RMBS transaction provided representations and warranties with 
respect  to  the  securitized  loans,  including  representations  with 
respect to the loan characteristics, the absence of borrower fraud 
in the underlying loan pools or other misconduct in the origination 
process and attesting to the compliance of loans with the prevailing 
underwriting  policies. Ambac  has  recorded  RMBS  subrogation 
recoveries, net of reinsurance, of $1.9 billion and $2.8 billion at 
December 31, 2016 and 2015, respectively. Refer to Note 2. Basis 
of  Presentation  and  Significant  Accounting  Policies  to  the 
Consolidated Financial Statements included in Part II, Item 8 in 
this  Form  10-K  for  more  information  regarding  the  estimation 
process for representation and warranty subrogation recoveries.

Losses and loss expenses (benefit) for the year ended December 
31, 2016, 2015, and 2014 were $(11.5) million,  $(768.7) million

$44.6 million for the year ended December 31, 2016, 2015, and 2014, 
respectively.  

Losses and loss expenses for 2016 were driven by the following:

continuous efforts and ongoing assessments of the value 
of our claims;

• 

Partially offset by $411.7 million of interest expense on 
Deferred Amounts accrued from the beginning of the 
accrual periods through December 31, 2014

• 

• 

Lower  projected  losses  in  the  RMBS  portfolio  due  to 
improved  deal  performance,  higher  representation  and 
warranty  subrogation  recoveries  and  a  second  quarter 
settlement  of  a  non-representation  and  warranty  dispute 
with regards to an Ambac insured RMBS transaction;

The  positive  impact  of  executed  commutations  and  an 
improved  outlook  with  regards  to  our  risk  remediation 
efforts on student loan policies primarily associated with 
student loan bonds acquired during the third quarter;

•  Higher projected losses in domestic public finance for the 
year ended December 31, 2016 largely driven by negative 
development in Puerto Rico.

• 

Increased projected losses in the Ambac UK portfolio for 
the year ended December 31, 2016 primarily due to foreign 
exchange losses of $77.6 million partially offset by lower 
interest rates.  The majority of Ambac UK's loss reserves 
are  denominated  in  currencies  other  than  its  functional 
currency  of  British  Pounds  resulting  in  incurred  losses 
(gains) when the British Pound depreciates (appreciates). 

Losses and loss expenses (benefit) for 2015 were driven by the 
following:

• 

• 

Lower  projected  losses  in  the  RMBS  portfolio  due  to 
improved  deal  performance,  lower  interest  rates  and  
increases in our estimate of RMBS subrogation recoveries 
as a result of continuous efforts and ongoing assessments 
of the value of our claims;

The  positive  impact  of  executed  commutations,    an 
improved  outlook  with  regards  to  our  risk  remediation 
efforts and lower interest rates on student loan policies;

•  Higher projected losses in domestic public finance for the 
year ended December 31, 2015 largely driven by negative 
development in Puerto Rico. 

•  Decrease in projected losses for the year ended December 
31, 2015 due to reduced claim expectations for an Ambac 
UK  transaction  resulting  from  proactive  remediation 
efforts and lower interest rates, partially offset by foreign 
exchange losses of $24.8 million.  The majority of Ambac 
UK's loss reserves are denominated in currencies other than 
its  functional  currency  of  British  Pounds  resulting  in 
incurred losses (gains) when the British Pound depreciates 
(appreciates).

Losses and loss expenses (benefit) for 2014 were driven by the 
following:

• 

Lower projected losses in the RMBS portfolio due to 
improved deal performance and increases in our estimate 
of RMBS subrogation recoveries as a result of

Morgan  and  $99.1  million  ($100.3  million  gross  of  reinsurance) 
related to the Countrywide Investor Settlement.

Operating  Expenses.    Operating  expenses  consist  of  gross 
operating  expenses  plus  reinsurance  commissions.  Reinsurance 
commissions are included in Financial Guarantee segment results.

Gross operating expenses for the year ended December 31, 2016
are $112.1 million, an increase of $9.8 million from gross operating 
expenses for the year ended December 31, 2015.  The increase was 
primarily due to the following:

•  Higher compensation costs related to severance and post 
employment costs, due to changes in CEO and reductions 
in  staff  partially  offset  by  reduced  salary  and    bonus 
expense.   

•  Higher  non-compensation  costs  related  to  stockholder 
activism,  the  establishment  of  $10  million  of  litigation 
contingencies, higher audit fees, increased outside services 
and  higher  regulatory  costs.  The  increase  in  non-
compensation costs were partially offset by reductions in 
premises costs and premium taxes.  Costs associated with 
stockholder activism amounted to $5.9 million and include 
legal, consulting and outside services fees.

redemption  of  approximately  26%  of  surplus  notes  (other  than 
junior surplus notes) in November 2014. This decline is offset by 
the  impact  of  the  July  2015  secured  borrowing  transaction 
described above and a full year of interest recognized following 
the sale of a junior surplus note originally issued to Ambac by the 
Segregated  Account  to  a  third  party  trust  in  August  2014.  
Subsequent to the sale, the junior surplus note is reflected as debt 
on Ambac's balance sheet along with other surplus notes and junior 
surplus notes held by third parties. 

Surplus note principal and interest payments require the approval 
of  OCI.  Annually  from  2011  through  2016,  OCI  issued  its 
disapproval  of  the  requests  of  Ambac  Assurance  and  the 
Rehabilitator of the Segregated Account, acting for and on behalf 
of the Segregated Account, to pay interest on outstanding surplus 
notes issued by Ambac and the Segregated Account on the annual 
scheduled  interest  payment  date  of  June 7th.    If  OCI  approves 
interest payments on surplus notes in the future, Ambac Assurance 
will also be required to pay interest accrued on certain repurchased 
surplus notes through the call option exercise dates. The amount 
of such unpaid interest on repurchased surplus notes is $4.0 million 
at December 31, 2016.

Neither Ambac Assurance nor the Rehabilitator of the Segregated 
Account, acting for and on behalf of the Segregated Account, have 
requested to pay interest on any junior surplus notes since their 
issuance. The interest of the outstanding surplus notes and junior 
surplus notes were accrued for and Ambac is accruing interest on 
the interest amounts following each scheduled interest payment 
date. 

Total accrued interest for surplus notes and junior surplus notes 
outstanding to third parties were $348.4 million and $78.0 million, 
respectively,  at  December  31,  2016.    Principal  and  interest 
payments on junior surplus notes cannot be made until all Ambac 
Assurance  (General Account)  and  Segregated Account  surplus 
notes are paid in full and after all Segregated Account future and 
existing senior indebtedness, policy and other priority claims have 
been paid in full. 

Provision for Income Taxes. The provision for income taxes for 
the  year  ended  December  31,  2016,  2015,  and  2014  was  $30.7 
million, $17.4 million, and $9.6 million, respectively. The income 
tax for all periods include (i) a provision for federal AMT taxes; 
(ii) a provision for pre-tax profits in Ambac UK’s Italian branch, 
which cannot be offset by losses in other jurisdictions.  The income 
tax for the year ended December 31, 2016 includes a provision for 
income tax due in respect of Ambac UK where operating losses 
brought forward from prior periods were fully utilized in the first 
quarter of 2016,  resulting in income tax now being payable.  

At  December 31,  2016  the  Company  had  $4.0  billion  of  U.S. 
Federal net ordinary operating loss carryforwards, including $1.4 
billion  at  Ambac  Financial  Group  and  $2.6  billion  at  Ambac 
Assurance.

Gross operating expenses for the year ended December 31, 2015 
are $102.3 million, an increase of $2.2 million from gross operating 
expenses for the year ended December 31, 2014.  The increase was 
primarily due to the following:

•  Higher compensation costs related to long term incentive 
compensation accruals, partially offset by lower salaries 
and medical benefits. 

•  Higher  non-compensation  costs  associated  with  the 
investigation  of  a    potential  recapitalization  of  Ambac 
Assurance  and  outside  services  fees  partially  offset  by 
lower directors' fees, premium taxes and subscriptions and 
data access costs.  Costs associated with the recapitalization 
of Ambac Assurance amounted to $4.8 million, an increase 
of $4.0 million from the year ended December 31, 2014.  
Lower  directors'  fees  are  primarily  related  to  a  special 
issuance of equity awards granted in December 2013 that 
vested in April 2014. 

As  a  consequence  of  the  Segregated  Account  Rehabilitation 
Proceedings,  the  Rehabilitator  retains  operational  control  and 
decision-making authority with respect to all matters related to the 
Segregated Account, including the hiring of advisers. Legal and 
consulting services provided for the benefit of OCI amounted to 
$6.4  million,  $5.6  million  and  $6.5  million  for  the  years  ended 
December 31, 2016, 2015 and 2014, respectively.  The increase in 
2016  compared  to  2015  is  driven  by  an  increase  in  monthly 
consulting adviser fees and higher legal fees as a result of a change 
in legal advisers.  The decrease in 2015 as compared to 2014 is 
primarily driven by a reduction in monthly legal adviser fees.  

Interest Expense.  Interest expense includes accrued interest on 
investment agreements, secured borrowing notes outstanding, and 
surplus  notes  issued  by Ambac Assurance  and  the  Segregated 
Account.    Additionally,  interest  expense  includes  discount 
accretion on surplus notes as their carrying value is at a discount 
to par.

The increase in interest expense for the year ended December 31, 
2016,  compared  to  2015  primarily  results  from  the  impact  of 
applying the level yield method as the discount to the face value 
of surplus notes accretes over time.   The year ended December 
31, 2016 also includes a full year of interest on a floating rate note 
issued on July 24, 2015 as part of a secured borrowing transaction 
of  Ambac  Assurance.  The  note  is  secured  by  certain  Ambac 
Assurance-wrapped  RMBS  securities  that  were  deposited  in  a 
bankruptcy  remote  trust.  The  trusts  used  to  effectuate  this 
transaction qualify as VIEs and are consolidated by Ambac.

The decrease in interest expense on surplus notes for the year ended 
December 31, 2015, compared to 2014 primarily results from the 
net  reduction  to  the  balance  of  outstanding  notes  from  the

LIQUIDITY AND CAPITAL RESOURCES

Ambac  Financial  Group,  Inc.  Liquidity. Ambac’s  liquidity  is 
primarily dependent on its cash and liquid investments of $212.1 
million as of December 31, 2016 and expense sharing and other 
arrangements with Ambac Assurance.  Ambac also has investments 
of $100.7 million in Ambac Assurance insured RMBS and surplus 
notes issued by Ambac Assurance, which, while less liquid than 
other  investments,  may  be  sold.    Pursuant  to  the  Mediation 
Agreement, Amended  TSA  and  Cost Allocation Agreement  (as 
each  such  term  is  defined  in  Note  1.  Background  and  Business 
Description to the Consolidated Financial Statements included in 
Part  II,  Item 8  in  this  Form  10-K,    the  following  are  potential 
additional sources of liquidity for Ambac:

limit  until  March  2017. 

•  According  to  the  Cost  Allocation  Agreement,  Ambac 
Assurance is required to reimburse reasonable operating 
expenses  incurred  by Ambac,  subject  to  an  annual  $5.0 
  Future  expense 
million 
reimbursements  are  at 
the 
rehabilitator subject to a $4.0 million per year limit.  In 
addition, Ambac Assurance  and Ambac  are  required  to 
reimburse  each  other  for  certain  operating  costs  and 
expenses  associated  with 
their  respective  business 
operations  in  accordance  with  prescribed  allocation 
procedures outlined the the Cost Allocation Agreement. 

the  sole  discretion  of 

•  According  to  the  Amended  TSA,  Ambac  Assurance  is 
required, under certain circumstances, to make payments 
to Ambac with respect to the utilization of net operating 
loss carry-forwards (“NOLs”). Any expected receipts with 
regard  to  the  utilization  of  NOLs  will  only  occur  after 
Ambac  Assurance  utilizes  NOLs  generated  after 
September 30, 2011. Ambac Assurance has utilized all of 
those NOLs and as a result of taxable income at Ambac 
Assurance in 2015, Ambac received $70.9 million in tax 
tolling  payments  in  April  2016  and  $0.5  million  in 
November  2016.  Additionally,  based  on  Ambac 
Assurance's  2016  results, Ambac  is  expected  to  receive 
approximately  $28.7  million  in  tax  tolling  payments  by 
May 2017 (subject to Rehabilitator review).  Future taxable 
income of Ambac Assurance will be subject to additional 
payments under the Amended TSA, after certain credits; 
provided that if Ambac Assurance generates NOLs in the 
future, the Amended TSA would permit it to utilize such 
NOLs without payment to Ambac.  

On August 28, 2014, Ambac deposited $350.0 million face amount 
of a junior surplus note issued to it by the Segregated Account, 
plus accrued but unpaid interest thereon, into a statutory trust (the 
"Trust")  in  exchange  for  net  proceeds  of  $224.3  million  and  a 

subordinated  owner 
(the  “Owner  Trust 
trust  certificate 
Certificate”)  issued  by  the  Trust  in  the  face  amount  of  $74.8 
million.  Proceeds from the transaction are expected to be used to 
fund select business transactions at Ambac offering attractive risk-
adjusted returns that, among other things, may permit utilization 
of Ambac’s tax net operating loss carry-forwards, select Ambac 
Assurance  liability  management  activities  and  for  general 
corporate  purposes.    The  Trust  funded  the  cash  portion  of  its 
purchase of the junior surplus note with proceeds of the private 
placement of $299.2 million face amount of senior secured notes 
(the  "Notes")  to  third  party  investors.  The  Notes  have  a  final 
maturity of August 28, 2039. Interest on the Notes accrues at 5.1% 
per annum and compounds annually on June 7th of each year up 
to and including the maturity date. Payments on the Notes will be 
made when and to the extent that the Segregated Account makes 
payments on the junior surplus note. The Notes must be paid in 
full  before  any  payments  will  be  made  on  the  Owner  Trust 
Certificate.  The  Notes  and  Owner  Trust  Certificate  are  non-
recourse to Ambac, Ambac Assurance and the Segregated Account, 
but are collateralized by the junior surplus note.  It is uncertain 
whether  and  to  what  extent Ambac  will  realize  value  from  the 
Owner Trust Certificate. 

It is highly unlikely that Ambac Assurance will be able to make 
dividend  payments  to  Ambac  for  the  foreseeable  future  and 
therefore current cash and investments and future payments under 
the  Cost Allocation Agreement  and  the Amended  TSA  will  be 
Ambac’s principal source of liquidity in the near term. Refer to 
Part  I,  Item 1,  “Insurance  Regulatory  Matters  -  Dividend 
Restrictions,  Including  Contractual  Restrictions”  and  Note  8. 
Insurance Regulatory Restrictions to the Consolidated Financial 
Statements included in Part II, Item 8, in this Form 10-K for more 
information on dividend payment restrictions. The principal use 
of liquidity is the payment of operating expenses, including costs 
to  explore  select  business  transactions  and  occasional  warrant 
repurchases. Contingencies could cause material liquidity strains. 

The  following  table  includes  aggregated  information  about 
contractual obligations for Ambac and its subsidiaries, excluding 
variable  interest  entities  consolidated  as  a  result  of  Ambac 
Assurance’s  financial  guarantee  contracts.  These  obligations 
include  payments  due  under  specified  contractual  obligations, 
aggregated  by  type  of  contractual  obligation,  including  claim 
payments,  principal  and 
interest  payments  under  Ambac 
the  Segregated  Account’s  surplus  notes, 
Assurance’s  and 
investment  agreement  obligations,  and  payments  due  under 
operating  leases.  The  table  and  commentary  below  reflect 
scheduled payments and maturities based on the original payment 
terms  specified  in  the  underlying  agreements  and  contracts,  or 
expected required payment dates if earlier.

Includes principal of and interest on surplus notes (excluding junior surplus notes) when due. All payments of principal and interest on surplus notes are 
subject to the prior approval of the OCI. If the OCI does not approve the payment of interest on the surplus notes, such interest will accrue and compound 
annually until paid. Annually from 2011 through 2016, OCI disapproved scheduled interest payments. Amounts in the table assume future approval by 
OCI for surplus notes (excluding junior surplus notes) for all principal and interest payments, including payment of previously deferred interest totaling 
$317.4 million on the next scheduled payment date of June 7, 2017. Additionally, all principal and interest payments on junior surplus notes (excluding 
part of the notes subject to periodically reduction as rent payments are made, as further described in Note 13. Long-term Debt to the Consolidated Financial

Includes principal of and interest on obligations using current rates for floating rate obligations. 

(3)  Amount represents future lease payments on lease agreements existing as of December 31, 2016. Ambac Assurance's lease with One State Street Plaza 
has a provision where Ambac Assurance can extend the lease of certain floors past the termination date of September 2019 to December 2029.  The above 
table does not reflect payments on those certain floors after the related lease expiry date of September 2019. 

(4)  Purchase obligations represent future expenditures for contractually scheduled fixed terms and amounts due for various technology-related maintenance 

agreements and other outside services. 

(5)  Amount represents future payments relating to Ambac Assurance's postretirement medical reimbursement benefits for current retirees over the next 10 

years. 

(6)  The timing of expected claim payments is based on deal specific cash flows, excluding expected recoveries. These deal specific cash flows are based on 
the expected cash flows of the underlying transactions (e.g. for RMBS credits we model estimated future claim payments). The timing of expected claim 
payments for credits with reserves that were established using our statistical loss reserve method is determined based on the weighted average expected 
life of the exposure. Refer to the Loss Reserves section in Note 2. Basis of Presentation and Significant Accounting Policies to the Consolidated Financial 
Statements included in Part II, Item 8 in this Form 10-K for further discussion of our statistical loss reserve method. The timing of these payments may 
vary significantly from the amounts shown above, especially for credits that are based on our statistical loss reserve method. As further described in Note 
1. Background and Business Description to the Consolidated Financial Statements included in Part II, Item 8 in this Form 10-K, following the effective 
date of the Segregated Account Rehabilitation Plan, as amended, the percentage of the initial cash Interim Payment for permitted policy claims increased 
from 25% to 45% with effect from July 21, 2014.  The Segregated Account will continue to make cash payments of 45% of each policy claim submitted 
and permitted in accordance with the Segregated Account Rehabilitation Plan, as amended (plus, in certain cases, Supplemental Payments or Special 
Policy Payments), subject to any further orders of the Rehabilitation Court or decisions of the Rehabilitator.  As with previously permitted policy claims, 
the remaining portion of the unpaid permitted policy claims (in this case, 55%) will remain outstanding as Deferred Amounts and, subject to the adjustment 
for Undercollateralized Bonds, will accrue interest at 5.1% per annum. These Deferred Amounts, together with interest thereon, may be paid from time 
to time in the future at the sole discretion of the Rehabilitator.  Unpaid claims include deferred policy claims of $2,994.1 and accrued interest on Deferred 
Amounts of $661.8 at December 31, 2016. We have included such unpaid amounts as obligations due in 2017.  Additionally, all future claim payments 
are included in their respective year at the estimated permitted claim amount. 

Ambac  Assurance  Liquidity.  Ambac  Assurance’s  liquidity  is 
dependent on the balance of liquid investments and, over time, the 
net impact of sources and uses of funds. The principal sources of 
Ambac Assurance’s liquidity are gross installment premiums on 
insurance  policies,  principal  and 
interest  payments  from 
investments,  sales  of  investments,  proceeds  from  repayment  of 
affiliate loans, recoveries on claim payments, litigation proceeds 
and reinsurance recoveries. Termination of installment premium 
policies  on  an  accelerated  basis  may  adversely  impact Ambac 
Assurance’s liquidity. The principal uses of Ambac Assurance’s 
liquidity  are  the  payment  of  operating  expenses,  claim  and 
commutation  payments  on  both  insurance  and  credit  derivative 
contracts, loss expenses, ceded reinsurance premiums, surplus note 
principal and interest payments (including Junior Surplus Notes), 
additional loans to affiliates and tax payments to Ambac, including 
tolling  payments  due  under  the  Amended  TSA.  Interest  and 
principal payments on surplus notes are subject to the approval of 
OCI,  which  has  full  discretion  over  payments  regardless  of  the 
liquidity position of Ambac Assurance. The level of claims paid 

by the Segregated Account is subject to the sole discretion of the 
Rehabilitator,  subject

to  any 

Ambac Assurance  manages  its  liquidity  risk  (by  currency)  by 
maintaining comprehensive analyses of projected cash flows and 
maintaining  specified level of cash and short-term investments at 
all times. 

As  more  fully  described  in  Note  1.  Background  and  Business 
Description to the Consolidated Financial Statements included in 
Part II, Item 8 in this Form 10-K:

• 

the Rehabilitator has sought and received approval from 
the Rehabilitation Court to make Supplemental Payments 
and Special Policy Payments with respect to certain insured 
securities. During the years ended December 31, 2016 and 
2015, 
the  Segregated  Account  made  Supplemental 
Payments and Special Policy Payments of $84.3 million 

| Ambac Financial Group, Inc.   52   2016 FORM 10-K |

• 

• 

and  $96.9  million,  respectively  in  respect  of  permitted 
policy claims. 

pursuant  to  the  injunctions  issued  by  the  Rehabilitation 
Court,  claims  on  policies  allocated  to  the  Segregated 
Account are not permitted to be paid during the Segregated 
Account Rehabilitation Proceedings until approved by the 
Rehabilitator.   The  Segregated  Account  is,  and  was, 
obliged  to  make  Interim  Payments  of  45%  of  each 
permitted policy claim to be paid on or after July 21, 2014 
in  accordance  with  the  amended  Segregated  Account 
Rehabilitation  Plan  and  associated  rules  and  guidelines.  
Under  the  Segregated  Account  Rehabilitation  Plan  the 
unpaid balance of Deferred Amounts will accrue interest 
until such outstanding policy obligations are paid in full. 
Interest on the Deferred Amounts currently accrue at 5.1%, 
is 
compounded  annually.  The  Segregated  Account 
responsible  for  Deferred  Amounts  and  unpaid  accrued 
interest  of  $2,994.1  million  and  $661.8  million, 
respectively  at  December 31,  2016.  Permitted  policy 
claims, including Deferred Amounts together with interest 
thereon, will be material uses of future liquidity.

the  Segregated  Account  will  establish  Junior  Deferred 
Amounts in respect of general claims, instead of issuing 
junior  surplus  notes  as  originally  contemplated.    Junior 
Deferred Amounts  will  generally  accrue  and  compound 
interest  at  an  annual  effective  rate  of  5.1%  and  will  be 
payable, as and when determined by the Rehabilitator, in 
his sole discretion.

Annually from 2011 through 2016, OCI issued its disapproval of 
the  requests  of Ambac Assurance  and  the  Rehabilitator  of  the 
Segregated Account, acting for and on behalf of the Segregated 
Account, to pay interest on outstanding surplus notes issued by 
Ambac  and  the  Segregated  Account  on  the  annual  scheduled 
interest payment date of June 7th.  Neither Ambac Assurance nor 
the  Rehabilitator  of  the  Segregated Account,  acting  for  and  on 
behalf of the Segregated Account, have requested to pay interest 
on any junior surplus notes since their issuance. Ambac Assurance 
and the Segregated Account are responsible for unpaid interest on 
surplus  and  junior  surplus  notes  of  $426.4  million  through 
December 31, 2016.

Furthermore, as more fully described in Note 1. Background and 
Business  Description  to  the  Consolidated  Financial  Statements 
included in Part II, Item 8 in this Form 10-K, on November 20, 
2014 the Rehabilitator early redeemed a portion of the surplus notes 
issued by the Segregated Account, together with interest thereon, 
which resulted in a proportionate redemption by Ambac Assurance 
of  its  surplus  notes.   Additionally,  on  December  22,  2014,  the 
Segregated  Account  made  equalizing  payments  of  Deferred 
Amounts, together with interest thereon.  The aggregate amount 
of payments for the partial redemption of Segregated Account and 
Ambac Assurance surplus notes owned by third parties, including 
accrued  interest,  was  $413.6  million  in  the  aggregate  and  the 
equalizing payments of Deferred Amounts was $1,137.2 million. 

Ambac Assurance is limited in its ability to pay dividends pursuant 
to the terms of its Auction Market Preferred Shares (“AMPS”), 
which state that dividends may not be paid on the common stock 
of Ambac Assurance unless all accrued and unpaid dividends on 
the AMPS for the then current dividend period have been paid, 

provided that dividends on the common stock may be made at all 
times for the purpose of, and only in such amounts as are necessary 
for enabling Ambac (i) to service its indebtedness for borrowed 
money as such payments become due or (ii) to pay its operating 
expenses.  If  dividends  are  paid  on  the  common  stock  for  such 
purposes,  dividends  on  the AMPS  become  cumulative  until  the 
date that all accumulated and unpaid dividends have been paid on 
the AMPS. Ambac Assurance has not paid dividends on the AMPS 
since 2010.  Refer to Part I, Item 1, “Insurance Regulatory Matters 
- Dividend Restrictions, Including Contractual Restrictions” and 
Note  8.  Insurance  Regulatory  Restrictions  to  the  Consolidated 
Financial Statements included in Part II, Item 8, in this Form 10-
K for more information on dividend payment restrictions. 

During  the  year  ended  December 31,  2016, Ambac Assurance 
received total subrogation of $1,355.4 million, net of reinsurance. 
Our ability to realize future R&W subrogation recoveries is subject 
to  significant  uncertainty,  including  risks  inherent  in  litigation, 
collectability of such amounts from counterparties (and/or their 
respective  parents  and  affiliates),  timing  of  receipt  of  any  such 
recoveries, intervention by the Rehabilitator or OCI which could 
impede  our  ability  to  take  actions  required  to  realize  such 
recoveries  and  uncertainty  inherent  in  the  assumptions  used  in 
estimating  such  recoveries.  The  amount  of  these  subrogation 
recoveries  is  significant  and  if  we  are  unable  to  recover  any 
amounts,  our  future  available  liquidity  to  pay  claims  would  be 
reduced materially. In January 2016, Ambac Assurance settled its 
RMBS-related disputes and litigation against JP Morgan Chase & 
Co. and certain of its affiliates (collectively "JP Morgan"). Pursuant 
to the settlement, JP Morgan paid Ambac Assurance $995.0 million 
($992.8 million net of reinsurance) in cash in return for releases 
of all of Ambac Assurance's claims against JP Morgan arising from 
certain RMBS transactions insured by Ambac Assurance.  Ambac 
Assurance also is entitled to other subrogation amounts relating to 
RMBS transactions and other contractual recoveries on public and 
structured  finance  policies.    Included  within  other  subrogation 
were estimated recoveries on certain insurance policies which were 
included in an omnibus settlement with investors in Countrywide 
securitizations, that was announced in June 2011 by Bank of New 
York Mellon, as Trustee, whereby Bank of America agreed to pay 
$8.5 billion across approximately 530 RMBS trusts (“Countrywide 
Investor  Settlement”).   Ambac  received  $100.3  million  ($99.1 
million  net  of  reinsurance)  related  to  the  Countrywide  Investor 
Settlement.

swaps 

various 

(“CDS”)  with 

A wholly-owned subsidiary of Ambac Assurance is a party to credit 
default 
commercial 
counterparties. Ambac  Assurance  guarantees  its  subsidiary’s 
payment  obligations  under  such  CDS. The  terms  of  such  CDS 
include  events  of  default  or  termination  events  based  on  the 
occurrence  of  certain  events,  or  the  existence  of  certain 
circumstances,  relating  to  the  financial  condition  of  Ambac 
Assurance,  including  the  commencement  of  an  insolvency, 
rehabilitation  or  like  proceeding. If  such  an  event  of  default  or 
termination  event  were  to  occur,  the  CDS  counterparties  could 
claim the contractual right to terminate the CDS and require Ambac 
Assurance,  as 
termination 
payments. Ambac  Assurance  estimates 
that  such  potential 
termination payments amount to $47.8 million as of December 31, 
2016. However, the Rehabilitation Court has issued an injunction 
barring the early termination of contracts based on the occurrence 
of events or the existence of circumstances like those described 
above. As a result, Ambac Assurance does not expect to make early 

financial  guarantor,

As described in Part I, Item 1, "Introduction" of this Form 10-K, 
one  of  Ambac's  primary  goals  is  to  create  shareholder  value 
commutations, 
through 
settlements and restructurings effected at Ambac Assurance that 
we believe will improve the Company's risk profile.  As Ambac 
Assurance takes such actions to reduce known and potential risks, 
liquidity may be materially affected.  Furthermore, such actions 
may negatively impact our operating results or financial position 
in one or more reporting periods.

intercompany 

Financial Services Liquidity. The principal uses of liquidity by 
Financial  Services  subsidiaries  are  payments  on  investment 
agreement  obligations,  payments  on 
loans, 
payments under derivative contracts (primarily interest rate swaps 
and  US  Treasury  futures),  collateral  posting  and  operating 
expenses. Management believes that its Financial Services’ short 
and long-term liquidity needs can be funded from net investment 
coupon receipts; the maturity of invested assets; sales of invested 
assets; intercompany loans from Ambac Assurance; and receipts 
from derivative contracts. 

As of December 31, 2016, Ambac had a $82.4 million contingent 
withdrawal  investment  agreement  outstanding  related  to  a 
structured  credit-linked  note  ("CLN").  This  one  remaining 
investment  agreement  matures  on  March  20,  2017  and  will  be 
funded by asset sales.   

While  meaningful  progress  has  been  made  in  unwinding  the 
Financial Services businesses, liquidity risk exists in the derivative 
portfolios due to contract provisions which may require collateral 
posting  or  early  termination  of  contracts.  Both  the  investment 
agreement and swap businesses borrows cash and securities from 
Ambac Assurance to meet liquidity needs when such borrowing is 
determined  to  be  most  economically  beneficial  to  Ambac 
Assurance.  Intercompany  loans  are  made  under  established 
lending  agreements  with  defined  borrowing  limits  that  have 
received non-disapproval from OCI.

Operating activities

The principal sources of Ambac's operating cash flows are gross 
installment premiums on insurance contracts, fees on credit default 
swap  contracts,  investment  coupon  receipts,  subrogation  and 
reinsurance recoveries. The principal uses of Ambac's liquidity are 

the  payment  of  operating  and  loss  expenses,  claim  and 
commutation payments on insurance contracts, ceded reinsurance 
premiums and tax payments.  During the years ended December 
31, 2016, 2015 and 2014,  Ambac had net loss and loss expense 
(recoveries)  payments  of  $(939.6)  million,  $1.1  million  and 
$1,067.3 million, respectively, inclusive of interest payments on 
Deferred  Amounts  of  $82.5  million  during  the  year  ended 
December 31, 2014.  In addition, during the  year ended December 
31,  2016,  2015  and  2014,  gross  premium  collection  and  credit 
derivative receipts by Ambac were $78.0 million, $110.9 million 
and $129.1 million, respectively. 

Future operating cash flows will primarily be impacted by the level 
of  premium  collections,  investment  coupon  receipts  and  claim 
payments (including further payments of Deferred Amounts and 
interest thereon) and payments under credit default swap contracts.   
Additional increases to Interim Payments, which are at the sole 
discretion  of  the  Rehabilitator,  will  have  an  adverse  effects  on 
Ambac's future cash flows. 

Financing Activities

Financing  activities  for  the  year  ended  December  31,  2016 
included  paydowns  on  a  secured  borrowing  of  $29.5  million, 
payments  for  investment  agreement  draws  of  $18.0  million, 
payments for extinguishment of long-term debt of $19.6 million
and the acquisition of Ambac warrants of $2.7 million. Financing 
activities for the  year ended December 31, 2015 included proceeds 
of  $129.9  million    (net  of  repayments  during  the  year  ended 
December 31, 2015) received from a secured borrowing, partially 
offset  by  payments  for  investment  agreement  draws  of  $63.9 
million, payments for extinguishment of long-term debt of $13.8 
million  and  the  acquisition  of Ambac  warrants  of  $5.0  million. 
Financing  activities  for  the  year  ended  December  31,  2014 
included redemption payments on surplus notes of $331.4 million
and  repayments  of  investment  agreements  of  $200.0  million, 
partially offset by proceeds from Ambac's sale of its Segregated 
Account junior surplus note in the amount of $224.3 million. 

Credit Ratings and Collateral. Ambac Assurance is no longer rated 
by Moody’s and S&P, which resulted in the triggering of required 
cure provisions in investment agreements. At December 31, 2016
Ambac posted collateral of $88.9 million in connection with its 
outstanding investment agreements. 

Ambac  Financial  Services,  LLC  (“AFS”)  provides  interest  rate 
swaps  for  states,  municipalities,  asset-backed  issuers  and  other 
entities in connection with their financings. AFS hedges interest 
rate risk of these instruments, as well as a portion of the interest 
rate  risk  in  the  financial  guarantee  portfolio,  with  standardized 
derivative contracts, including financial futures contracts, which 
contain  collateral  or  margin  requirements.  Under  these  hedge 
agreements, AFS  is  required  to  post  collateral  or  margin  to  its 
counterparties  and  futures  commission  merchants  to  cover 
unrealized losses. In addition, AFS is required to post collateral or 
margin in excess of the amounts needed to cover unrealized losses. 
All AFS derivative contracts containing ratings-based downgrade 
triggers  that  could  result  in  collateral  or  margin  posting  or  a 
termination  have  been  triggered.  If  terminations  were  to  occur, 
AFS would be required to make termination payments but would 
also receive a return of collateral or margin in the form of cash, 
U.S. Treasury or U.S. government agency obligations with market 
values equal to or in excess of market values of the swaps and 
futures contracts. In most cases, AFS will look to re-establish hedge

positions that are terminated early. This may result in additional 
collateral  or  margin  obligations.  The  amount  of  additional 
collateral or margin posted on derivatives contracts will depend 
on several variables including the degree to which counterparties 
exercise  their  termination  rights  (or  agreements  terminate 
automatically) and the terms on which hedges can be replaced. All 
collateral and margin obligations are currently met. Collateral and 
margin  posted  by AFS  totaled  a  net  amount  of  $202.6  million, 
including 
these  contracts  at 
December 31, 2016.

BALANCE SHEET

Total  assets  decreased  by  approximately  $1,092  million  from 
December 31,  2015  to  $22.6  billion  at  December 31,  2016, 
primarily due to (i) declines in VIE assets primarily as a result of 
devaluation of assets denominated in British Pounds; (ii) lower 
premium receivables from the runoff, including early terminations, 
of  the  insured  portfolio;  (iii)  amortization  of  the  insurance 
intangible  asset  and  (iv)  lower  subrogation  recoveries;  partially 
offset by an increase in investments and cash receipts from R&W 
settlements of $995 million and from the Countrywide Investor 

Settlement of $100.3 million that exceeded amounts previously 
included as a component of Subrogation recoverable assets. 

Total liabilities decreased by approximately $1,112 million from 
December 31,  2015  to  $20.7  billion  as  of  December 31,  2016, 
primarily as a result of (i)  declines in VIE liabilities primarily as 
a result of devaluation of liabilities denominated in British Pounds; 
(ii) lower unearned premium reserves; partially offset by higher 
accrued interest payables on  Surplus Notes and higher loss and 
loss expense reserves, resulting primarily from the impact of the 
R&W recovery noted above on loss and loss expense reserves.

As of December 31, 2016 total stockholders’ equity was $1,978 
million, compared with total stockholders’ equity of $1,958 million
at December 31, 2015. This increase was primarily due to Other 
Comprehensive Income during the period.  Other Comprehensive 
Income during 2016 was driven by net income and unrealized gains 
on investment securities partially offset by unrealized losses from 
foreign currency translations.

Includes investments guaranteed by Ambac Assurance and Ambac UK.  Refer to Note 10. Investments of the Consolidated Financial Statements included 
in Part II Item 8 for further discussion of Ambac-insured securities held in the investment portfolio.   

The  weighted  average  rating,  which  is  based  on  the  lower  of 
Standard & Poor’s or Moody’s ratings, of the mortgage and asset-
backed  securities  portfolios  is  CC  and  BB-  as  of  December 31, 
2016, and CC and BBB- as of December 31, 2015, respectively.

Ambac’s  fixed  income  portfolio  includes  securities  covered  by 
guarantees  issued  by  Ambac  Assurance  and  other  financial 
guarantors  (“insured  securities”),  which  may  from  time  to  time 
include bonds issued by the Commonwealth of Puerto Rico or its 
agencies or instrumentalities. The published rating agency ratings 
on these securities reflect the higher of the financial strength rating 

of the financial guarantor or the rating of the underlying issuer. 
Rating agencies do not always publish separate underlying ratings 
(those ratings excluding the insurance by the financial guarantor) 
because  the  insurance  cannot  be  legally  separated  from  the 
underlying security by the insurer. In the event these underlying 
ratings  are  not  available  from  the  rating  agencies, Ambac  will 
assign  an  internal  rating.    Refer  to  Note  10.  Investments  to  the 
Consolidated  Financial Statements included in Part II, Item 8 in 
this Form 10-K for further details on securities insured by Ambac 
Assurance.

(1)  Ratings are based on the lower of Moody’s or S&P ratings. If ratings are unavailable from Moody's or S&P, Fitch ratings are used.  If guaranteed, rating 

represents the higher of the underlying or guarantor’s financial strength rating.  

(2)  Below investment grade and not rated bonds insured by Ambac represent 45% and 41% of the 2016 and 2015 combined portfolio, respectively.

The increase in the percentage of not rated and below investment grade holdings since December 31, 2015 is driven by additional purchases 
of Ambac insured bonds.

(1)  Since the table is presented in millions, securities with market values and unrealized losses that are less than $0.1 will be shown as zero.

Management  has  determined  that  the  unrealized  losses  in 
available-for-sale securities are primarily driven by increases in 
interest  rates  and  shifts  in  market  risk  and  liquidity  premiums 
demanded by fixed income investors. Ambac has concluded that 
unrealized  losses  reflected  in  the  table  above  are  temporary  in 
nature  based  upon  (a) there  being  no  unexpected  principal  and 
interest payment defaults on these securities; (b) an analysis of the 

creditworthiness  of  the  issuer  and  financial  guarantor,  as 
applicable, and analysis of projected defaults on the underlying 
collateral; (c) management having no intent to sell these securities; 
and (d) it being not more likely than not that Ambac will be required 
to sell these debt securities before the anticipated recovery of its 
amortized cost basis.

Insurance Intangible Asset.  At the Fresh Start Reporting Date, 
an insurance intangible asset was recorded which represented the 
difference between the fair value and aggregate carrying value of 
the  financial  guarantee  insurance  and  reinsurance  assets  and 
liabilities. For the year ended December 31, 2016 and 2015, the 
insurance intangible amortization expense was $175 million and 
$170 million, respectively.  As of December 31, 2016 and 2015, 
the  gross  carrying  value  of  the  insurance  intangible  asset  was 
$1,534 million and $1,627 million, respectively.  The decrease in 
gross carrying value at December 31, 2016 from December 31, 
2015  was  due  to  changes  in  foreign  currency  related  to  the 
insurance  intangible  at  consolidated  companies  with  functional 
currencies other than  the US dollar.  Accumulated amortization 

of  the  insurance  intangible  asset  was  $572  million  and  $414 
million, as of December 31, 2016 and 2015, respectively, resulting 
in  a  net  insurance  intangible  asset  of  $962  million  and  $1,212 
million, respectively. 

Derivative  Liabilities.  The  interest  rate  derivative  products 
portfolio is positioned to benefit from rising rates as an economic 
hedge against interest rate exposure in the Company, including the 
financial guarantee portfolio.  Derivative liabilities decreased from 
$353 million to $319 million primarily due to increases in interest 
rates during 2016.  The valuation of derivative liabilities (credit 
derivatives and interest rate swaps) is impacted by the market’s 
view  of Ambac Assurance’s  credit  quality.  We  reflect Ambac’s 
credit quality in the fair value of such liabilities by including a

CVA in the determination of fair value, whereas a lower (higher) 
CVA, in isolation, would result in an increase (decrease) in the 
liability. Ambac reduced its derivative liabilities by $46.9 million 
at December 31, 2016 and $88.8 million at December 31, 2015 to 
incorporate the market’s view of Ambac’s credit quality. The lower 
CVA as of December 31, 2016 is a function of (i) changes to the 
underlying derivative liabilities before considering Ambac's credit 
quality  and  (ii) the  market’s  view  that  Ambac’s  credit  quality 
improved during the year ended December 31, 2016. 

Loss and Loss Expense Reserves. Loss and loss expense reserves 
are based upon estimates of the ultimate aggregate losses inherent 
in the non-derivative financial guarantee portfolio for insurance 

policies  issued  to  beneficiaries,  including  unconsolidated VIEs.  
Loss  and  loss  expense  reserves  include  the  unpaid  portion  of 
interest accrued on Deferred Amounts established pursuant to the 
amended Segregated Account Rehabilitation Plan. The evaluation 
process for determining the level of reserves is subject to certain 
estimates and judgments.

The loss and loss expense reserves net of subrogation recoverables 
and  before reinsurance as of December 31, 2016 and 2015 were 
$3,696 million and $2,859 million, respectively.

Ambac has exposure to various bond types issued in the debt capital 
markets. Our experience has shown that, for the majority of bond 
types, we have not experienced significant claims. The bond types 
that  have  experienced  significant  claims,  including  through 
commutations,  are 
residential  mortgage-backed  securities 
(“RMBS”)  and  student  loan  securities.  These  two  bond  types 
represent 89% of our ever-to-date insurance claims recorded with 
RMBS comprising 84%.  Although historically RMBS and student 

loan securities have been the largest source of claim activity there 
are reserves on Public Finance and Ambac UK credits that may 
result in significant claim payments in the future. We have observed 
that, with respect to certain bond types, it is reasonably possible 
that a material change in actual loss severities and defaults could 
occur  over  time.  In  the  future,  our  experience  may  differ  with 
respect to the types of guaranteed bonds affected or the magnitude 
of  the  effect.    Refer  to  the  "Critical  Accounting  Policies  and 
Estimates" section of this Management’s Discussion and Analysis 
of  Financial  Condition  and  Results  of  Operations  for  further 
discussion of the potential variability of expected future loss and 
recoveries. 

The  table  below  indicates  gross  par  outstanding  and  the 
components  of  gross  loss  and  loss  expense  reserves  related  to 
policies  in  Ambac’s  gross  loss  and  loss  expense  reserves  at

RMBS

Ambac  has  exposure  to  the  U.S.  mortgage  market  primarily 
through  direct  financial  guarantees  of  RMBS, 
including 
transactions collateralized by first and second liens.  Gross loss 
and loss expense reserves increased primarily due to the reduction 
in  estimated  future  recoveries  as  a  result  of  collections  from 
settlements with JP Morgan (R&W) and Countrywide (investor 
settlement) as well as other RMBS subrogation receipts.  This was 
partially offset by an increase in estimated future recoveries related 
to  a  settlement  reached,  outside  of  litigation,  of  a  dispute  with 
regards to an Ambac insured RMBS transaction.

We established a representation and warranty subrogation recovery 
as  further  discussed  in  "Critical  Accounting  Policies  and 
Estimates" section of this Management’s Discussion and Analysis 
of Financial Condition and Results of Operations in addition to the 
Basis of Presentation and Significant Accounting Policies and Loss 
Reserves sections included in Note 2. Basis of Presentation and 
Significant Accounting Policies and Note 7. Financial Guarantee 

Insurance Contracts, respectively, of the Consolidated Financial 
Statements  included  in  Part  II,  Item 8  in  this  Form 10-K.    Our 
ability to realize RMBS representation and warranty recoveries is 
subject  to  significant  uncertainty,  including  risks  inherent  in 
litigation, collectability of such amounts from counterparties (and/
or their respective parents and affiliates), timing of receipt of any 
such recoveries, intervention by the Rehabilitator or OCI which 
could impede our ability to take actions required to realize such 
recoveries,  and  uncertainty  inherent  in  the  assumptions  used  in 
estimating such recoveries.

The table below distinguishes between RMBS credits for which 
we have not established a representation and warranty subrogation 
recovery and those for which we have, providing in both cases the 
gross  par  outstanding,  gross  loss  reserves  before  representation 
and warranty subrogation recoveries, and gross loss reserves net 
of  representation  and  warranty  subrogation  recoveries  for  all 
RMBS  exposures  for  which  Ambac  established  reserves  at

Ambac’s U.S. public finance portfolio consists predominantly of 
municipal bonds such as general and revenue obligations and lease 
and tax-backed obligations of state and local government entities; 
however,  the  portfolio  also  comprises  a  wide  array  of  non-
municipal types of bonds, including financings for not-for-profit 
entities and transactions with public and private elements, which 

generally finance infrastructure, housing and other public purpose 
facilities and interests.  The increase in public finance gross loss 
reserves at December 31, 2016 as compared to December 31, 2015 
was  primarily  related  to  adverse  developments  in  Puerto  Rico

ACCOUNTING STANDARDS

Please  refer  to  Note  2.  Basis  of  Presentation  and  Significant 
Accounting  Policies  to  the  Consolidated  Financial  Statements, 
included in Part II, Item 8 in this Form 10-K, for a discussion of 
the  impact  of  recent  accounting  pronouncements  on  Ambac’s 
financial condition and results of operations.

AMBAC ASSURANCE STATUTORY BASIS FINANCIAL 
RESULTS

Ambac  Assurance,  Everspan  and  the  Segregated  Account’s 
statutory  financial  statements  are  prepared  on  the  basis  of 
accounting  practices  prescribed  or  permitted  by  the  OCI.  OCI 
recognizes  only  statutory  accounting  practices  prescribed  or 
permitted by the State of Wisconsin (“SAP”) for determining and 
reporting the financial condition and results of operations of an 
insurance company for determining its solvency under Wisconsin 
Insurance  Law.  The  National  Association  of 
Insurance 
Commissioners (“NAIC”) Accounting Practices and Procedures 
manual  (“NAIC  SAP”)  has  been  adopted  as  a  component  of 
prescribed practices by the State of Wisconsin.  OCI has prescribed 
or permitted additional accounting practices for Ambac Assurance, 
Everspan and the Segregated Account which are described in Note 
8. Insurance Regulatory Restrictions to the Consolidated Financial 
Statements included in Part II, Item 8 in this Form 10-K.  As a 
result  of  these  prescribed  and  permitted  practices,  Ambac 
Assurance’s policyholder surplus at December 31, 2016 and 2015 
was higher by $17.3 million and $21.3 million, respectively, than 
if Ambac Assurance and the Segregated Account had reported such 
amounts in accordance with NAIC SAP. 

Under  Wisconsin  insurance  law,  the  Segregated  Account  is  a 
separate insurer from Ambac Assurance and accordingly is subject 
to  all  of  the  filing  and  statutory  reporting  requirements  of 
Wisconsin domiciled insurers.  The total assets, total liabilities, 
and total surplus of the Segregated Account are reported as discrete 
components of Ambac Assurance’s assets, liabilities, and surplus 
in  Ambac  Assurance’s  statutory  basis  financial  statements. 
Accordingly, Ambac Assurance’s  statutory  financial  statements 
include the results of Ambac Assurance’s general account and, to 
the  extent  allowable  under  a  prescribed  accounting  practice  by 
OCI, the Segregated Account. Pursuant to this prescribed practice, 
the  results  of  the  Segregated Account  are  not  fully  included  in 
Ambac  Assurance’s  statutory  financial  statements  if  Ambac 
Assurance’s  surplus  is  (or  would  be)  less  than  $100.0  million 
(“Minimum  Surplus  Amount”).    Maintaining  the  Minimum 
Surplus  Amount  could  result  in  a  reduction  in  the  liabilities 
assumed  by  Ambac  Assurance  from  the  Segregated  Account.  
Please refer to Note 1. Background and Business Description of 
the  Consolidated  Financial  Statements  in  Part  II,  Item 8  of  this 
Form 10-K for additional information on the establishment of the 

Ambac Assurance’s statutory policyholder surplus and qualified 
statutory capital (defined as the sum of policyholders surplus and 
mandatory  contingency  reserves)  were  $976.5  million  and 
$1,368.3 million at December 31, 2016, respectively, as compared 
to  $624.8  million  and  $1,015.7  million  at  December 31,  2015, 
respectively. The  Segregated  Account’s  statutory  policyholder 
surplus  amount  was  $381.3  million  and  $387.6  million  as  of 
December 31, 2016 and 2015, respectively. At December 31, 2016 
and 2015, Ambac Assurance’s surplus as regards to policyholders 
exceeds the Minimum Surplus Amount. In the event that Ambac 
Assurance does not maintain surplus in excess of the Minimum 
Surplus  Amount,  the  Segregated  Account  would  experience  a 
shortfall in funds available to pay its liabilities. Any such shortfall 
would be a consideration for the Rehabilitator in the determination 
of whether any changes to the Segregated Account Rehabilitation 
Plan (as defined above) and/or the amount of partial policy claim 
payments  are  necessary  or  appropriate  or  whether  to  institute 
general rehabilitation proceedings against Ambac Assurance. 

Ambac Assurance’s increase in policyholder surplus was primarily 
due to statutory net income.  Statutory net income was primarily 
due  to  positive  loss  development,  premium  earnings  and 
investment income which was partially offset by the accrual of 
interest on Deferred Amounts. 

The Segregated Account’s decrease in policyholder surplus was 
primarily due to a reduction in junior surplus notes as a result of 
rent payments made by Ambac Assurance during the year ended 
December 31, 2016. 

Ambac Assurance’s statutory policyholder surplus includes $374.0 
million of junior surplus notes issued by the Segregated Account, 
including  $350.0  million  that Ambac  deposited  into  a  statutory 
trust (as further discussed within Liquidity and Capital Resources 
in  this  Management's  Discussion  and  Analysis).  These  junior 
surplus  notes,  as  well  as  preferred  stock  issued  by  Ambac 
Assurance  with  a  liquidation  value  of  $660.3  million,  are 
obligations that have claims on the resources of Ambac Assurance 
and  the  Segregated  Account  which  impact  Ambac's  ability  to 
realize residual value from its equity in Ambac Assurance.

Ambac  Assurance’s  statutory  surplus  is  sensitive  to  multiple 
factors,  including:  (i) loss  reserve  development  (inclusive  of 
Segregated Account reserves and interest on Deferred Amounts), 
(ii) approval by OCI of interest payments on existing surplus notes 
issued  by  Ambac  Assurance  or 
the  Segregated  Account, 
(iii) approval by OCI of principal or interest payments on existing 
junior  surplus  notes  issued  by  the  Segregated  Account,  (iv) 
deterioration  in  the  financial  position  of  Ambac  Assurance 
subsidiaries  that  have  their  obligations  guaranteed  by  Ambac 
Assurance, (v) first time payment defaults of insured obligations, 
which  increase  statutory  loss  reserves,  (vi) commutations  of 
insurance policies or credit derivative contracts at amounts that 
differ  from  the  amount  of  liabilities  recorded,  (vii) reinsurance 
contract  terminations  at  amounts  that  differ  from  net  assets 
recorded, (viii) changes to the fair value of investments carried at 
fair value, (ix) settlements of representation and warranty breach 
claims at amounts that differ from amounts recorded, including 
failures  to  collect  such  amounts,  (x) realized  gains  and  losses, 
including losses arising from other than temporary impairments of 

| Ambac Financial Group, Inc.   64   2016 FORM 10-K |

investment securities, and (xi) future changes to prescribed SAP 
practices by the OCI. 

As of December 31, 2016, total unpaid interest, which will require 
OCI approval for payment, for surplus notes outstanding to third 
parties  and  junior  surplus  notes  was  $313.3  million  and  $65.3 
million, respectively at the scheduled interest payment date of June 
7,  2016.    Additionally,  if  OCI  approves  interest  payments  on 
current  Ambac  Assurance  surplus  notes  in  the  future,  Ambac 
Assurance will be required to pay interest on certain repurchased 
surplus notes through their call option exercise dates. The amount 
of such unpaid interest on repurchased surplus notes is $4.0 million 
at December 31, 2016.  Under SAP, these amounts will be recorded 
as a liability once approval for payment has been granted by OCI.   

The significant differences between GAAP and SAP are that under 
SAP: 

• 

Loss reserves are only established for losses on guaranteed 
obligations  that  have  defaulted    in  an  amount  that  is 
sufficient  to  cover  the  present  value  of  the  anticipated 
defaulted debt service payments over the expected period 
of  default,  less  estimated  recoveries  under  subrogation 
rights  (5.1%  as  prescribed  by  OCI).  Loss  reserves  are 
established for non-defaulted policies on the date when a 
the 
binding  commutation  contract 
counterparty. 
the 
  Under  GAAP, 
establishment  of  loss  reserves  for  defaulted  obligations, 
loss reserves are established (net of GAAP basis unearned 
premium revenue) for obligations that have experienced 
credit  deterioration,  but  have  not  yet  defaulted  using  a 
weighted-average  risk-free  discount  rate,  currently  at 
2.7%. 

is  signed  by 
to 
in  addition 

•  Mandatory contingency reserves are required based upon 
the  type  of  obligation  insured,  whereas  GAAP  does  not 
require such a reserve. Releases of the contingency reserves 
are  generally  subject  to  OCI  approval  and  relate  to  a 
determination that the held reserves are deemed excessive. 

• 

Investment grade fixed income investments are stated at 
amortized cost and certain below investment grade fixed 
income investments are reported at the lower of amortized 
cost  or  fair  value.  Under  GAAP,  all  fixed  income 
investments are reported at fair value. 

•  Wholly owned subsidiaries are not consolidated; rather, the 
equity  basis  of  accounting  is  utilized  and  the  carrying 
values  of  these  investments  are  subject  to  admissibility 
tests. When Ambac Assurance’s share of the subsidiaries’ 
losses exceeds the related carrying amounts of the wholly 
owned 
subsidiary,  Ambac  Assurance  discontinues 
applying the equity method and the investment is reduced 
to zero. For those subsidiaries that have insufficient claims 
paying resources and whose obligations are guaranteed by 
Ambac Assurance, Ambac Assurance records an estimated 
impairment for probable losses which are in excess of the 
subsidiaries’ claims paying resources. 

•  Variable interest entities are not required to be assessed for 
consolidation. Under GAAP, a reporting entity that has both 
the following characteristics is required to consolidate the 
VIE: a) the power to direct the activities of the VIE that 

impact 

the  VIE’s 

significantly 

most 
economic 
performance; and b) the obligation to absorb losses of the 
VIE or the right to receive benefits from the VIE that could 
potentially be significant to the VIE. Ambac generally has 
the  obligation  to  absorb  losses  of  VIEs  that  could 
potentially  be  significant  to  the  VIE  as  the  result  of  its 
guarantee  of  insured  obligations  issued  by  VIEs.  For 
certain VIEs Ambac Assurance has the power to direct the 
most  significant  activities  of  the  VIE  and  accordingly 
consolidates the related VIEs under GAAP. 

•  All payments of principal and interest on the surplus notes 
are subject to the approval of the OCI.  Unpaid interest due 
on  the  surplus  notes  is  expensed  when  the  approval  for 
payment of interest has been granted by the OCI.  Under 
GAAP, interest on surplus notes is accrued regardless of 
OCI approval. 

•  Upfront  premiums  written  are  earned  on  a  basis 
proportionate to the remaining scheduled debt service to 
the original total principal and interest insured. Installment 
premiums are reflected in income pro-rata over the period 
covered  by  the  premium  payment.  When  an  insurance 
policy  has  been  legally  defeased,  the  related  portion  of 
unearned premium revenue is accelerated and recognized 
as premiums earned.  Under GAAP, premium revenues for 
both upfront and installment premiums are earned over the 
life of the financial guarantee contract in proportion to the 
insured  principal  amount  outstanding  at  each  reporting 
date. When an insured bond has been retired, any remaining 
UPR is recognized at that time to the extent the financial 
guarantee  contract 
legally  extinguished,  causing 
accelerated  premium  revenue.  For  installment  premium 
paying  transactions,  we  offset  the  recognition  of  any 
remaining UPR by the reduction of the related premium 
receivable to zero, which may cause negative accelerated 
premium  revenue.    For  bonds  that  are  legally  defeased, 
generally  through  a  refunding  or  a  pre-refunding,  the 
remaining unearned premium revenue is not accelerated 
but is recognized over the remaining life of the defeasance 
period.

is 

• 

Fresh start financial statement reporting is not a concept 
within SAP.  Under GAAP, Ambac determined that fresh 
start financial statement reporting was to be applied upon 
our  emergence  from  Chapter  11.  Fresh  start  financial 
reporting requires Ambac to adjust the historical carrying 
of  its  assets  and  liabilities  to  fair  value,  including  an 
insurance intangible asset which represented the difference 
between the fair value and aggregate carrying value of the 
financial guarantee insurance and reinsurance assets and 
liabilities. This insurance intangible asset is amortized as 
an expense on a level yield basis over the life of the related 
insurance risks. 

AMBAC UK FINANCIAL RESULTS UNDER UK 
ACCOUNTING PRINCIPLES

Ambac UK is required to prepare financial statements under FRS 
102 "The Financial Reporting Standard applicable in the UK and 
Republic  of  Ireland."  Ambac  UK’s  shareholder  funds  under 
UK GAAP  were  £112.0  million  at  December 31,  2016  as 
compared to £47.8 million at December 31, 2015. Ambac UK’s 

| Ambac Financial Group, Inc.   65   2016 FORM 10-K |

improvement  in  shareholders’  funds  was  primarily  due  to  net 
income arising from the receipt of premiums, investment return in 
the period and reduction in loss provisions.  At December 31, 2016, 
the carrying value of cash and investments was £436.6 million, an 
increase from £384.7 million at December 31, 2015. The increase 
in  cash  and  investments  is  due  to  the  continued  receipt  of 
premiums,  investment  coupons  from  Ambac  UK's  investment 
portfolio and increases in the value of investments in pooled funds.  
The  increase  in  the  value  of  investments  in  pooled  funds  were 
partially  due  to  upward  revaluations  of  Ambac  UK's  foreign 
currency investments following the fall in the value of the British 
Pound  as  compared  to  the  US  Dollar  since  a  portion  of  the 
investments are denominated in US Dollars.

The significant differences between U.S. GAAP and UK GAAP 
are that under UK GAAP: 

• 

• 

• 

Loss reserves are only established for losses on guaranteed 
obligations  when,  in  the  judgment  of  management,  a 
monetary default in the timely payment of debt service is 
likely to occur, which would result in Ambac UK incurring 
a loss. A loss provision is established in an amount that is 
sufficient  to  cover  the  present  value  (currently  using  a 
discount rate of 3.45%) of the anticipated defaulted debt 
service payments over the expected period of default, less 
estimated  recoveries  under  subrogation  rights.  The 
discount rate is equal to the lower of the rate of return on 
invested  assets  for  either  the  current  year  or  the  period 
covering  the  current  year  plus  the  four  previous  years. 
Under U.S. GAAP, loss reserves are established (net of U.S. 
GAAP basis unearned premium revenue) for obligations 
that have experienced credit deterioration, but have not yet 
defaulted using a weighted-average risk-free discount rate, 
currently at 1.8% for Ambac UK related transactions. 

Investments  in  fixed  income  securities  are  stated  at 
amortized  cost,  subject 
to  an  other-than-temporary 
impairment evaluation. Under U.S. GAAP, all bonds are 
reported at fair value. 

Purchases of Ambac UK insured securities are bifurcated 
into an intrinsic and an Ambac UK claim based value.  The 
intrinsic value is recorded as an investment whereas the 
Ambac  UK  claim  based  value  is  recorded  as  a  claim 
payment with an accompanying reduction in Ambac UK 
loss reserves.  Under U.S. GAAP, purchases of Ambac UK 
insured securities are reported as investments and do not 
reduce loss reserves.

•  Variable  interest  entities  (“VIE”)  are  not  required  to  be 
assessed for consolidation. Under U.S. GAAP, a reporting 
entity that has both the following characteristics is required 
to consolidate the VIE: a) the power to direct the activities 
of  the  VIE  that  most  significantly  impact  the  VIE’s 
economic  performance;  and  b)  the  obligation  to  absorb 
losses of the VIE or the right to receive benefits from the 
VIE that could potentially be significant to the VIE. Ambac 
generally has the obligation to absorb losses of VIEs that 
could potentially be significant to the VIE as the result of 
its guarantee of insured obligations issued by VIEs. For 
certain VIEs Ambac UK has the power to direct the most 
significant  activities  of 
the  VIE  and  accordingly 
consolidates the related VIEs under U.S. GAAP. 

•  Upfront  premiums  written  are  earned  on  a  basis 
proportionate to the remaining scheduled debt service to 
the  total  principal  and  interest  insured.  Installment 
premiums are reflected in income pro-rata over the period 
covered  by  the  premium  payment.  Under  U.S.  GAAP, 
premium  revenues  for  both  upfront  and  installment 
premiums are earned over the life of the financial guarantee 
contract  in  proportion  to  the  insured  principal  amount 
outstanding at each reporting date. 

Beginning January 1, 2016 Ambac UK is also required to prepare 
financial information in accordance with the Solvency II Directive.  
The  basis  of  preparation  of  this  information  is  significantly 
different from both US GAAP and UK GAAP.  Capital resources 
under Solvency II were a deficit of £112.8 million at September 30, 
2016 as compared to £89.8 million at January 1, 2016.  The deficit 
at September 30, 2016 and January 1, 2016 are in comparison to 
a  regulatory  capital  requirement  of  £381.2  million  and  £361.1 
million  as  of  September 30,  2016  and  January  1,  2016, 
respectively.  Ambac  UK  is  therefore  deficient  in  terms  of 
compliance  with  applicable  regulatory  capital  requirements  by 
£494.0m million and £451.0 million at September 30, 2016 and 
January 1, 2016, respectively.  The regulators are aware of this 
deficiency and dialogue between Ambac UK management and its 
regulators remains ongoing with respect to options for addressing 
the shortcoming, although such options remain few.

The capital resources and capital requirements of Ambac UK as 
calculated  in  accordance  with  the  Solvency  II  Directive  at 
December 31, 2016 will be made available by May 20, 2017 on 
Ambac’s website.

NON-GAAP FINANCIAL MEASURES

In addition to reporting the Company’s quarterly financial results 
in accordance with GAAP, the Company reports two non-GAAP 
financial measures: Adjusted Earnings and Adjusted Book Value. 
The  most  directly  comparable  GAAP  measures  are  net  income 
attributable  to  common  stockholders  for Adjusted  earnings  and 
Total  Ambac  Financial  Group,  Inc.  stockholders’  equity  for 
Adjusted  Book  value.    A  non-GAAP  financial  measure  is  a 
numerical measure of financial performance or financial position 
that  excludes  (or  includes)  amounts  that  are  included  in  (or 
excluded from) the most directly comparable measure calculated 
and presented in accordance with GAAP. We are presenting these 
non-GAAP  financial  measures  because  they  provide  greater 
transparency and enhanced visibility into the underlying drivers 
of our business and the impact of certain items that the Company 
believes will reverse from GAAP book value over time through 
the  GAAP  statements  of  comprehensive  income.  Adjusted 
Earnings  and Adjusted  Book  Value  are  not  substitutes  for  the 
Company’s GAAP reporting, should not be viewed in isolation and 
may differ from similar reporting provided by other companies, 
which may define non-GAAP measures differently.

Ambac has a significant U.S. tax net operating loss (“NOL”) that 
is offset by a full valuation allowance in the GAAP consolidated 
financial statements. As a result of this and other considerations, 
for purposes of non-GAAP measures, we utilized a 0% effective 
tax rate; which is subject to change. 

In response to a recent comment letter received from the Division 
the  Securities  and  Exchange 
of  Corporation  Finance  of 

| Ambac Financial Group, Inc.   66   2016 FORM 10-K |

Commission, Ambac has implemented the following changes to 
its non-GAAP measures effective December 31, 2016: 

ASC,  whether  or  not  they  are  subject  to  derivative 
accounting rules.

•  Operating Earnings - Ambac has changed the name of its 
non-GAAP  measure  “Operating  Earnings”  to  “Adjusted 
Earnings”.

• 

Financial  guarantee  variable  interest  entities  (“VIEs”)  - 
Ambac  no  longer  eliminates  the  effects  of  VIEs  in  the 
calculation  of  its  non-GAAP  measures  for  Adjusted 
Earnings and Adjusted Book Value.  However, Ambac has 
separately  disclosed  the  effects  of  VIEs  on  its  GAAP 
financial  statements  that  were  previously  included  as 
adjustments to its non-GAAP measures.  These disclosures 
can be found below the Adjusted Earnings and Adjusted 
Book Value non-GAAP reconciliation tables in this section.

For comparative purposes, prior period amounts have been recast 
in the non-GAAP reconciliation tables shown below to conform 
to the new presentation.  For further information regarding how 
our  non-GAAP  measures  were  reported  prior  to  December  31, 
2016  please  refer  to  our  September  30,  2016  Form  10-Q  and 
previous Form 10-Q and Form 10-K filings.

The  following  paragraphs  define  each  non-GAAP  financial 
measure and describe why it is useful. A reconciliation of the non-
GAAP financial measure and the most directly comparable GAAP 
financial measure is also presented below.

Adjusted Earnings. Adjusted Earnings is defined as net income 
attributable  to  common  stockholders,  as  reported  under  GAAP, 
adjusted on an after-tax basis for the following:

• 

Non-credit  impairment  fair  value  (gain)  loss  on  credit 
derivatives: Elimination of the non-credit impairment fair 
value  gains  (losses)  on  credit  derivatives,  which  is  the 
amount  in  excess  of  the  present  value  of  the  expected 
estimated  credit  losses.  Such  fair  value  adjustments  are 
heavily affected by, and in part fluctuate with, changes in 
market  factors  such  as  interest  rates  and  credit  spreads, 
including the market’s perception of Ambac’s credit risk 
(“Ambac  CVA”),  and  are  not  expected  to  result  in  an 
economic  gain  or  loss.  These  adjustments  allow  for  all 
financial guarantee segment contracts to be accounted for 
consistent with the Financial Services – Insurance Topic of 

• 

• 

Insurance  intangible  amortization  and  impairment  of 
goodwill: Elimination of the amortization of the financial 
guarantee  insurance  intangible  asset  and  impairment  of 
goodwill that arose as a result of Ambac’s emergence from 
bankruptcy  and  the  implementation  of  Fresh  Start 
reporting.  These  adjustments  ensure  that  all  financial 
guarantee segment contracts are accounted for consistent 
with the provisions of the Financial Services – Insurance 
Topic of the ASC.

Foreign  exchange  (gains)  losses:  Elimination  of  the 
foreign exchange gains (losses) on the re-measurement of 
assets,  liabilities  and  transactions  in  non-functional 
currencies.  For periods prior to 2016, we eliminated the 
foreign exchange gains (losses) on the re-measurement of 
net premium receivables and loss and loss expense reserves 
in non-functional currencies.  Given the long-duration of 
a significant portion of these premium receivables and loss 
reserves,  the  foreign  exchange  re-measurement  gains 
(losses) are not necessarily indicative of the total foreign 
exchange  gains  (losses)  that  Ambac  will  ultimately 
recognize.  Beginning  in  2016,  we  have  eliminated  the 
foreign exchange gains (losses) on all assets, liabilities and 
transactions in non-functional currencies. Expanding this 
adjustment to include all foreign exchange gains (losses) 
enables users of our financial statements to better view the 
business  results  without  the  impact  of  fluctuations  in 
foreign currency exchange rates, particularly as assets held 
in  non-functional  currencies  have  grown,  and  facilitates 
period-to-period  comparisons  of  Ambac's  operating 
performance.  Note  that  we  have  not  recast  prior  period 
adjustments  to  conform  to  the  methodology  as  such 
amounts were not material.

• 

Fair value (gain) loss on derivative products from Ambac 
CVA: Elimination of the gains (losses) relating to Ambac’s 
CVA on derivative contracts other than credit derivatives. 
Similar  to  credit  derivatives,  fair  values  include  the 
market’s  perception  of  Ambac’s  credit  risk  and  this 
adjustment only allows for such gain or loss when realized.

(1)  Refer to the description of the foreign exchange (gain) loss adjustment above this table for a discussion of the change in methodology that was effective 

for the three and nine months ended September 30, 2016.

Net income (loss) effects of financial guarantee VIE consolidation: 
VIEs  that  were  consolidated  as  a  result  of  financial  guarantees 
provided by Ambac are accounted for on a fair value basis. The 
impact  on  Net  income  attributable  to  common  stockholders  of 
these consolidated VIEs was $(14.1) million, $31.6 million , and 
$(32.2) million for the years ended December 31, 2016, 2015 and 
2014,  respectively.  Had  these  financial  guarantee  VIEs  been 
accounted  for  under  the  provisions  of  the  Financial  Services  - 
Insurance Topic of the ASC, the impact on Net income attributable 
to common stockholders would have been $147.6 million, $42.7 
million, and $13.2 million for the years ended December 31, 2016, 
2015  and  2014,  respectively.  The  net  impact  of  these  different 
accounting  bases  on  Net  income  attributable  to  common 
stockholders  (including  per  share  amounts)  was  $161.7  million 
($3.54 per diluted share), $11.1 million ($0.24 per diluted share), 
and $45.4 million ($0.96 per diluted share), for the years ended 
December  31,  2016,  2015  and  2014,  respectively.  This  is 
supplemental information only and is not a component of Adjusted 
Earnings.

Adjusted Book Value. Adjusted Book Value is defined as Total 
Ambac  Financial  Group,  Inc.  stockholders’  equity  as  reported 
under GAAP, adjusted for after-tax impact of the following:

• 

Non-credit  impairment  fair  value  losses  on  credit 
derivatives: Elimination of the non-credit impairment fair 
value  loss  on  credit  derivatives,  which  is  the  amount  in 
excess  of  the  present  value  of  the  expected  estimated 
economic credit loss. GAAP fair values are heavily affected 
by, and in part fluctuate with, changes in market factors 
such  as  interest  rates,  credit  spreads,  including Ambac’s 
CVA that are not expected to result in an economic gain or 
loss. These adjustments allow for all financial guarantee 
segment  contracts  to  be  accounted  for  within Adjusted 
Book Value consistent with the provisions of the Financial 
Services—Insurance Topic of the ASC, whether or not they 
are subject to derivative accounting rules.

• 

Insurance  intangible  asset:  Elimination  of  the  financial 
guarantee insurance intangible asset that arose as a result 
the 
of  Ambac’s  emergence  from  bankruptcy  and 

• 

• 

• 

implementation of Fresh Start reporting. This adjustment 
ensures that all financial guarantee segment contracts are 
accounted for within Adjusted Book Value consistent with 
the provisions of the Financial Services—Insurance Topic 
of the ASC.

Ambac  CVA  on  derivative  product  liabilities  (excluding 
credit  derivatives):  Elimination  of  the  gain  relating  to 
Ambac’s  CVA  embedded  in  the  fair  value  of  derivative 
contracts  other  than  credit  derivatives.  Similar  to  credit 
derivatives, fair values include the market’s perception of 
Ambac’s  credit  risk  and  this  adjustment  only  allows  for 
such gain when realized.

Net  unearned  premiums  and  fees  in  excess  of  expected 
losses:  Addition  of  the  value  of  the  unearned  premium 
revenue  ("UPR")  on  financial  guarantee  contracts,  in 
excess of expected losses, net of reinsurance.  This non-
GAAP  adjustment  presents  the  economics  of  UPR  and 
expected  losses  for  financial  guarantee  contracts  on  a 
consistent basis. In accordance with GAAP, stockholders’ 
equity reflects a reduction for expected losses only to the 
extent they exceed UPR.  However, when expected losses 
are less than UPR for a financial guarantee contract, neither 
expected losses nor UPR have an impact on stockholders’ 
equity. This non-GAAP adjustment adds UPR in excess of 
expected losses, net of reinsurance, to stockholders’ equity 
for financial guarantee contracts where expected losses are 
less than UPR.

Net unrealized investment (gains) losses in Accumulated 
Other  Comprehensive  Income:  Elimination  of 
the 
unrealized gains and losses on the Company’s investments 
that  are  recorded  as  a  component  of  accumulated  other 
comprehensive income (“AOCI”). The AOCI component 
of  the  fair  value  adjustment  on  the  investment  portfolio 
may  differ  from  realized  gains  and  losses  ultimately 
recognized  by  the  Company  based  on  the  Company’s 
investment strategy. This adjustment only allows for such 
gains and losses in Adjusted Book Value when realized.

Stockholders'  equity  effects  of 
financial  guarantee  VIE 
consolidation: VIEs that were consolidated as a result of financial 
guarantees provided by Ambac are accounted for on a fair value 
basis. The impact on Total Ambac Financial Group, Inc. ("AFG") 
stockholders' equity of these consolidated VIEs was $132.4 million 
and $28.7 million at December 31, 2016 and 2015, respectively. 
Had these financial guarantee VIEs been accounted for under the 
provisions of the Financial Services Insurance Topic of the ASC, 
the impact on AFG stockholders' equity would have been $139.2 
million  and  $(123.1)  million  at  December  31,  2016  and  2015, 
respectively. The net impact of these different accounting bases on 
AFG stockholders' equity (including per share amounts) was $6.7 
million ($0.15 per share) and $(151.8) million ($3.37 per share), 
at December 31, 2016 and 2015, respectively.  This is supplemental 
information only and is not a component of Adjusted Book Value.

Factors that impact changes to Adjusted Book Value include many 
of the same factors that impact Adjusted Earnings, including the 
majority  of  revenues  and  expenses,  but  generally  exclude 
components of premium earnings since they are embedded in prior 
period's Adjusted Book Value through the net unearned premiums 
and fees in excess of expected losses adjustment.  Net unearned 
premiums and fees in excess of expected losses will affect Adjusted 
Book Value for (i) changes to future premium assumptions (e.g. 
expected term, interest rates, foreign currency rates, time passage) 
and (ii) changes to expected losses for policies which do not exceed 
their  related  unearned  premiums.  The  Adjusted  Book  Value 
increase  from  December 31,  2015  to  December 31,  2016  was 
primarily  driven  by Adjusted  earnings,  partially  offset,  as  was 
shareholders'  equity,  by  foreign  exchange  losses  resulting 
primarily as a consequence of the Brexit referendum vote.

Item 7A.   Quantitative  and  Qualitative  Disclosures 
about Market Risk

Market risk represents the potential for losses that may result from 
changes in the value of a financial instrument as a result of changes 

in market conditions. The primary market risks that would impact 
the value of Ambac’s financial instruments are interest rate risk, 
credit spread risk and foreign currency exchange risk. Below we 
discuss  each  of  these  risks  and  the  specific  types  of  financial 
instruments  impacted.  Senior  managers  are  responsible  for 
developing and applying methods to measure risk. The estimation 
of  potential  losses  arising  from  adverse  changes  in  market 
conditions  is  a  key  element  in  managing  market  risk.  Ambac 
utilizes  various  systems,  models  and  sensitivity  scenarios  to 
monitor and manage market risk. These models include estimates, 
made by management, which utilize current and historical market 
information. The valuation results from these models could differ 
materially  from  amounts  that  would  actually  be  realized  in  the 
market.  Financial instruments of VIEs that are consolidated as a 
result  of  Ambac's  financial  guarantees  are  excluded  from  the 
market risk measures below. 

Interest Rate Risk:

Financial instruments for which fair value may be affected by 
changes in interest rates consist primarily of fixed income 
investment securities, loans, investment agreements, long-term 
debt and interest rate derivatives.  Interest rate increases 
(decreases)would also have a negative (positive) economic 
impact on expected future claim payments within the financial 
guarantee portfolio. Fixed income investment securities that are 
guaranteed by Ambac have interest rate characteristics that 
behave inversely to those associated with future financial 
guarantee claim payments.   Accordingly, such securities are 
excluded from the interest rate sensitivity table below.  

The following table summarizes the estimated change in fair value 
(based primarily on the valuation methodology discussed in Note 
9.  Fair  Value  Measurements  to  the  Consolidated  Financial 
Statements included in Part II, Item 8 in this Form 10-K) on these 
financial  instruments,  assuming  immediate  changes  in  interest 
rates at specified levels at December 31, 2016:

(2)  Due to the low interest rate environment as of December 31, 2016, stress scenarios involving interest rate declines greater than 200 basis points are not 

meaningful to Ambac's portfolios.

Changes in fair value resulting from changes in interest rates are 
driven  primarily  by  the  impact  of  interest  rate  shifts  on  the 
investment portfolio and loans (which declines in value as rates 
increase) and the interest rate swap portfolio, long-term debt and 
investment agreements (which increases in value as rates increase). 
The interest rate derivatives portfolio is managed with the goal of 
retaining  some  interest  rate  sensitivity  as  an  economic  hedge 
against the effects of rising interest rates elsewhere in the Company, 
including on Ambac’s financial guarantee exposures (the “macro-
hedge”).    The  interest  rate  sensitivity  of  the  interest  rate  swap 
portfolio attributable to the macro-hedge position would produce 
mark-to-market gains or losses of approximately $0.6 million for 
a  1  basis  point  parallel  shift  in  USD  swap  rates  up  or  down  at 
December 31, 2016.  The impact of the macro-hedge is included 
in the interest rate sensitivity table above.   

The estimation of potential losses arising from adverse changes in 
market  relationships,  known  as  “Value-at-Risk”  (“VaR”),  is  a 
consideration in management’s monitoring of interest rate risk for 
the  interest  rate  swap  portfolio.  Ambac  has  developed  a  VaR 
methodology  to  estimate  potential  losses  using  a  one  day  time 
horizon and a 99% confidence level. This means that Ambac would 
expect to incur losses due to changes in interest rates greater than 
that predicted by VaR estimates only once in every 100 trading 
days, or about 2.5 times a year. Ambac’s methodology estimates 
VaR using a 300-day historical “look back” period. This means 
that changes in market values are simulated using market inputs 
from the past 300 days.  For the year ended December 31, 2016, 
Ambac’s 
interest  rate  derivative  portfolio  VaR  averaged 
approximately  $15.2  million,  and  ranged  from  a  high  of  $16.2 
million to a low of $14.3 million. These VaR measures are intended 

| Ambac Financial Group, Inc.   69   2016 FORM 10-K |

to focus on the impact of observable market rates and therefore 
exclude  fair  value  adjustments  made  by  management  to 
risk.  Ambac 
incorporate  Ambac  or  counterparty  credit 
supplements its VaR methodology, which it believes is a good risk 
management  tool  in  normal  markets,  by  performing  scenario 
testing to measure the potential for losses in volatile markets. These 
scenario  tests  include  parallel  and  non-parallel  shifts  in  the 
benchmark interest rate curve.

Credit Spread Risk:

Financial instruments that may be adversely affected by changes 
in spreads include Ambac’s outstanding credit derivative contracts, 
certain interest rate swap contracts and investment assets. Changes 

in  spreads  are  generally  caused  by  changes  in  the  market’s 
perception of the credit quality of the underlying obligor. Market 
liquidity  and  prevailing  risk  premiums  demanded  by  market 
participants are also reflected in spreads and impact valuations.

The following table summarizes the estimated change in fair values 
on Ambac’s net derivative liabilities  assuming immediate parallel 
shifts in reference obligation credit spreads related to written credit 
derivatives  and  counterparty  credit 
to 
uncollateralized interest rate swaps at December 31, 2016.  It is 
more  likely  that  actual  changes  in  credit  spreads  will  vary  by 
obligor:

Also included in the fair value of credit derivative liabilities is the 
effect  of  Ambac’s  creditworthiness,  which  reflects  market 
perception of Ambac’s ability to meet its obligations. Incorporating 
estimates  of  Ambac’s  credit  valuation  adjustment  into  the 
determination of fair value has resulted in a $1.9 million reduction 
to  the  credit  derivatives  liability  as  of  December 31,  2016.   At 
December 31, 2016 the credit valuation adjustment resulted in a 
11.1%  reduction  of  the  credit  derivative  liability  as  measured 
before considering Ambac credit risk. Refer to Note 9. Fair Value 
Measurements to the Consolidated Financial Statements included 
in  Part  II,  Item  8  in  this  Form  10-K  for  further  information  on 
measurement of the credit valuation adjustment.

The  fair  value  of  interest  rate  swaps  may  also  be  affected  by 
changes to the credit valuation adjustment attributable to the risk 

of Ambac  non-performance.  Generally,  the  need  for  an Ambac 
credit  valuation  adjustment  is  mitigated  by  the  existence  of 
collateral posting agreements under which adequate collateral has 
been posted. Derivative contracts entered into with credit exposure 
to  financial  guarantee  customers  are  not  typically  subject  to 
collateral  posting  agreements.  Estimates  of  Ambac’s  credit 
valuation  adjustment  included  in  the  fair  value  of  interest  rate 
swaps reduced the derivative liability fair value by $44.9 million 
as of December 31, 2016.

The following table summarizes the estimated change in fair values 
on Ambac's credit derivative and interest rate swap net liabilities 
assuming  immediate  shifts  in  Ambac  credit  spreads  used  to 
determine the CVA at December 31, 2016:

Ambac’s  fixed  income  investment  portfolio  contains  securities

estimated  change  in  fair  values  of  Ambac’s  fixed  income

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders
Ambac Financial Group, Inc.:

We have audited Ambac Financial Group, Inc. and subsidiaries' (the “Company” or “Ambac”) internal control over financial reporting as of 
December 31, 2016, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring 
Organizations of the Treadway Commission (COSO). The Company's management is responsible for maintaining effective internal control over 
financial  reporting  and  for  its  assessment  of  the  effectiveness  of  internal  control  over  financial  reporting,  included  in  the  accompanying 
Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control 
over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards 
require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was 
maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk 
that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. 
Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides 
a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial 
reporting  and  the  preparation  of  financial  statements  for  external  purposes  in  accordance  with  generally  accepted  accounting  principles. A 
company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in 
reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance 
that  transactions  are  recorded  as  necessary  to  permit  preparation  of  financial  statements  in  accordance  with  generally  accepted  accounting 
principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors 
of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition 
of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any 
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or 
that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, Ambac maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016, based on 
criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway 
Commission (COSO).

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated 
balance sheets of Ambac as of December 31, 2016 and 2015, and the related consolidated statements of comprehensive income, stockholders’ 
equity, and cash flows for each of the years in the three-year period ended December 31, 2016, and our report dated February 28, 2017, expressed 
an unqualified opinion on those consolidated financial statements. The opinion refers to Note 1, which describes factors that raise substantial 
doubt about Ambac’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The 
consolidated financial statements do not include any adjustments that might result from the outcome of these uncertainties.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders
Ambac Financial Group, Inc.:

We have audited the accompanying consolidated balance sheets of Ambac Financial Group, Inc. and subsidiaries (the “Company”) as of 
December 31, 2016 and 2015, and the related consolidated statements of comprehensive income, stockholders’ equity and cash flows for each 
of the years in the three-year period ended December 31, 2016.  In connection with our audits of the consolidated financial statements, we 
also have audited the related financial statement schedules in this Form 10-K. These consolidated financial statements and financial statement 
schedules are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial 
statements and financial statement schedules based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards 
require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. 
An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes 
assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement 
presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Ambac 
Financial Group, Inc. and subsidiaries as of December 31, 2016 and 2015, and the results of their operations and their cash flows for each of 
the the years in the three-year period ended December 31, 2016 in conformity with U.S. generally accepted accounting principles. Also in our 
opinion, the related financial statement schedules, when considered in relation to the consolidated financial statements taken as a whole, present 
fairly, in all material respects, the information set forth therein.

The accompanying consolidated financial statements and financial statement schedules have been prepared assuming that the Company will 
continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the significant deterioration of the guaranteed 
portfolio has adversely impacted the financial condition of the Company’s operating subsidiary, Ambac Assurance Corporation resulting in 
significant regulatory oversight by the Office of the Commissioner of Insurance of the State of Wisconsin, including the rehabilitation of a 
segregated account of Ambac Assurance Corporation. This raises substantial doubt about the Company’s ability to continue as a going concern. 
Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements and financial statement 
schedules do not include any adjustments that might result from the outcome of these uncertainties.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company's 
internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control - Integrated Framework 
(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated February 28, 2017
expressed an unqualified opinion on the effectiveness of the Company's internal control over financial reporting.

Notes to Consolidated Financial Statements
(Dollar Amounts in Thousands, Except Share Amounts)

1.        BACKGROUND AND BUSINESS DESCRIPTION 

Background:

Ambac Financial Group, Inc. (“Ambac” or the “Company”), headquartered in New York City, is a financial services holding company that 
was  incorporated  in  the  state  of  Delaware  on April 29,  1991.  On  May 1,  2013  (the  “Effective  Date”), Ambac  emerged  from  Chapter  11 
bankruptcy protection when the Second Modified Fifth Amended Plan of Reorganization of Ambac Financial Group, Inc. (the “Reorganization 
Plan”) became effective. On December 26, 2013, the United States Bankruptcy Court for the Southern District of New York (the “Bankruptcy 
Court”) entered an order of final decree closing Ambac’s Chapter 11 case. Ambac filed a voluntary petition for relief under Chapter 11 of the 
United States Bankruptcy Code (the “Bankruptcy Code”) in the Bankruptcy Court on November 8, 2010 as a result of losses incurred since 
the beginning of the financial crisis in 2007.

As provided for in the Reorganization Plan, Ambac’s Amended and Restated Certificate of Incorporation and revised Bylaws became effective 
on  the  Effective  Date.  On  February  28,  2014, Ambac’s  Bylaws  were  amended,  primarily  to  (i)  revise  the  advance  notice  provisions  for 
stockholders proposing business or nominating directors; (ii) add procedural and disclosure requirements for stockholders proposing business 
or nominating directors, calling special meetings or taking action by written consent; (iii) add a forum selection clause specifying state or 
federal courts located in the State of Delaware as the sole and exclusive forum for proceedings which, among other things, (A) are brought 
on behalf of Ambac, (B)claim breaches of fiduciary duty, (C) involve claims arising under Ambac’s governing documents or the Delaware 
General Corporation Law, or (D) are governed by the internal affairs doctrine; and (iv) update other bylaw provisions, including revisions 
related to the use of electronic communication technologies. Pursuant to the Amended and Restated Certificate of Incorporation of Ambac, 
Ambac is authorized to issue 150,000,000 shares of capital stock, consisting of 130,000,000 shares of common stock, par value $0.01 per 
share and 20,000,000 shares of preferred stock, par value $0.01 per share. Pursuant to the Reorganization Plan, Ambac distributed 45,000,000
shares of new common stock on May 1, 2013 and distributed warrants to holders of allowed general unsecured claims and subordinated debt 
securities, which as of the Effective Date entitled such holders to acquire an additional 5,047,138 shares of new common stock of the Company 
at an exercise price of $16.67 per share at any time on or prior to April 30, 2023. The new common stock and warrants are listed on NASDAQ 
and trade under the symbols “AMBC” and “AMBCW,” respectively. All such common stock and warrants were issued without registration 
under the Securities Act of 1933, as amended or state securities laws, in reliance on Section 1145 of the United States Bankruptcy Code. The 
common stock of the Company in existence prior to the Effective Date was cancelled on the Effective Date. 

Ambac’s Amended and Restated Certificate of Incorporation limits voting and transfer rights of stockholders in significant ways. Article IV 
contains voting restrictions applicable to any person owning at least 10% of Ambac’s common stock so that such person (including any group 
consisting of such person and any other person with whom such person or any affiliate or associate of such person has any agreement, contract, 
arrangement or understanding with respect to acquiring, voting, holding or disposing of Ambac’s common stock) shall not be entitled to cast 
votes in excess of one vote less than 10% of the votes entitled to be cast by all common stock holders, except as otherwise approved by OCI. 

There are substantial restrictions on the ability to transfer Ambac’s common stock set forth in Article XII of Ambac’s Amended and Restated 
Certificate of Incorporation. In order to preserve certain tax benefits, subject to limited exceptions, any attempted transfer of common stock 
shall be prohibited and void to the extent that, as a result of such transfer (or any series of transfers of which such transfer is a part), either 
(i) any person or group of persons shall become a holder of 5% or more of the Company’s common stock or (ii) the percentage stock ownership 
interest in Ambac of any holder of 5% or more of the Company’s common stock shall be increased (a “Prohibited Transfer”). These restrictions 
shall not apply to an attempted transfer if the transferor or the transferee obtains the written approval of Ambac’s Board of Directors to such 
transfer. A purported transferee of a Prohibited Transfer shall not be recognized as a stockholder of Ambac for any purpose whatsoever in 
respect of the securities which are the subject of the Prohibited Transfer (the “Excess Securities”). Until the Excess Securities are acquired by 
another person in a transfer that is not a Prohibited Transfer, the purported transferee of a Prohibited Transfer shall not be entitled with respect 
to such Excess Securities to any rights of stockholders of Ambac, including, without limitation, the right to vote such Excess Securities and 
to receive dividends or distributions, whether liquidating or otherwise, in respect thereof, if any. Once the Excess Securities have been acquired 
in a transfer that is not a Prohibited Transfer, the securities shall cease to be Excess Securities. If the Board determines that a transfer of 
securities constitutes a Prohibited Transfer then, upon written demand by Ambac, the purported transferee shall transfer or cause to be transferred 
any certificate or other evidence of ownership of the Excess Securities within the purported transferee’s possession or control, together with 
any distributions paid by Ambac with respect to such Excess Securities, to an agent designated by Ambac. Such agent shall thereafter sell such 
Excess Securities and the proceeds of such sale shall be distributed as set forth in the Amended and Restated Certificate of Incorporation. If 
the purported transferee of a Prohibited Transfer has resold the Excess Securities before receiving such demand, such person shall be deemed 
to have sold the Excess Securities for Ambac’s agent and shall be required to transfer to such agent the proceeds of such sale, which shall be 
distributed as set forth in the Amended and Restated Certificate of Incorporation. 

As of the Effective Date, the Company was generally discharged and released from all pre-Effective Date debts, liabilities, claims, causes of 
action and interests in accordance with the provisions of the Reorganization Plan. Holders of claims and equity interests are also generally 
barred from commencing or continuing any action or proceeding relating to such claims, causes of action or interests. The Reorganization 
Plan also provides for broad exculpation and releases of the Company, Ambac Assurance, the Segregated Account (as defined below), OCI,

the Rehabilitator, the board of directors and board committees of the Company and Ambac Assurance, all individual directors, officers and 
employees of the Company and Ambac Assurance, the Creditors’ Committee and the individual members thereof, and each of the respective 
representatives of such parties, for actions or omissions that occurred on or prior to the Effective Date. 

Business Description:

Ambac has two reportable business segments: Financial Guarantee and Financial Services. 

Ambac’s financial guarantee business segment is conducted through its primary operating subsidiary, Ambac Assurance Corporation (“Ambac 
Assurance”), and its wholly owned subsidiary, Ambac Assurance UK Limited (“Ambac UK”), both of which have been in runoff since 2008. 
Insurance policies issued by Ambac Assurance and Ambac UK generally guarantee payment when due of the principal and interest on the 
obligations guaranteed. Ambac Assurance also has another wholly-owned financial guarantee subsidiary, Everspan Financial Guarantee Corp. 
(“Everspan”), which has been in runoff since its acquisition in 1997. The deterioration of Ambac Assurance’s financial condition resulting 
from losses in its insured portfolio since 2007 has prevented Ambac Assurance from being able to write new business. An inability to write 
new business has and will continue to negatively impact Ambac’s future operations and financial results. Ambac Assurance’s ability to pay 
dividends and, as a result, Ambac’s liquidity, have been significantly restricted by the deterioration of its financial condition, by the rehabilitation 
of  the  Segregated Account  (as  defined  below)  and  by  the  terms  of  the  Settlement Agreement,  dated  as  of  June 7,  2010  (the  "Settlement 
Agreement"), by and among Ambac Assurance, Ambac Credit Products LLC (“ACP”), Ambac and certain counterparties to credit default 
swaps with ACP that were guaranteed by Ambac Assurance. Ambac Assurance is also restricted in its ability to pay dividends pursuant to 
regulatory restrictions, the terms of its Auction Market Preferred Shares, and the terms of agreements entered into with the Segregated Account. 
It is highly unlikely that Ambac Assurance will be able to make dividend payments to Ambac for the foreseeable future. 

Ambac’s financial services business segment is currently conducted through subsidiaries of Ambac Assurance, which provide financial and 
investment products, including investment agreements, funding conduits and interest rate swaps, principally to the clients of its financial 
guarantee business. Ambac Assurance insures all of the obligations of its financial services subsidiaries. These businesses are in active runoff, 
which is being effectuated by transaction terminations, settlements, and scheduled amortization of contracts. The Financial Services business 
also maintains interest rate derivatives to mitigate exposure to floating rate insured obligations in the Financial Guarantee segment. 

Ambac’s primary goal is to maximize shareholder value through executing the following key strategies: 

•  Active runoff of Ambac Assurance and its subsidiaries  through  transaction  terminations,  policy  commutations, settlements  and 

restructurings that we believe will improve our risk profile, and maximizing the risk-adjusted return on invested assets;

• 

• 

• 

• 

Loss recovery through litigation and exercise of contractual and legal rights;

Improved cost effectiveness and efficiency of the operating platform; 

Rationalization of Ambac's and its subsidiaries' capital and liability structures, enabling simplification of corporate governance and 
facilitating the successful rehabilitation of the Segregated Account (as defined below); and

Selective business transactions offering attractive risk-adjusted returns that, among other things, may permit utilization of Ambac’s 
net operating loss carry-forwards.

Ambac Assurance is evaluating the possibility of entering into one or more transactions to improve the financial condition of Ambac Assurance 
which may, subject to OCI approval, lead to the conclusion of the Segregated Account Rehabilitation Proceedings.  In pursuing this objective, 
Ambac Assurance is considering the possibility of monetizing certain assets, restructuring or exchanging certain outstanding debt and insurance 
obligations, and/or commuting or reducing insured exposures.  Ambac Assurance is also discussing with OCI potential options for addressing 
outstanding Segregated Account and other obligations.  From time to time Ambac Assurance has also discussed, and intends to continue 
discussing, with counterparty creditors and OCI a potential transaction pursuant to which outstanding Deferred Amounts and surplus notes, 
in each case including accrued interest, would be exchanged for or satisfied by indebtedness, or other instruments which may include securities, 
and cash or other assets. In evaluating potential transactions, we understand that OCI intends to consider, among other things, their impact on 
the company and policyholders, and we intend to consider, among other things, their impact on the company and our stakeholders, including, 
in each case, their legal, regulatory and tax implications.  

However, Ambac Assurance has not reached any agreement on the terms of any such transaction, and we cannot provide any assurance that 
any such transaction will be consummated by Ambac Assurance in the future, or if it is, as to the timing, terms or conditions of any such 
transaction, or as to whether it could lead to the conclusion of the Segregated Account Rehabilitation Proceedings.  Any such transaction 
proposed by Ambac Assurance would be subject to the prior approval of the board of directors of Ambac Assurance, OCI and the Rehabilitation 
Court and may require third-party consents, which may not be obtained.  OCI has not indicated a course of action to address Segregated 
Account or other obligations or to conclude the Segregated Account Rehabilitation Proceedings.  As stated in the Supplement (as defined 
below), the goal of the SDC (as defined below) is to provide additional directional guidance regarding the status of the Segregated Account 
rehabilitation during the first quarter of 2017, barring any unforeseen developments that might impede that effort. The terms, conditions, and

AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements
(Dollar Amounts in Thousands, Except Share Amounts)

timing of a potential conclusion of the Segregated Account Rehabilitation Proceedings are in the sole discretion of OCI, and subject to the 
approval of the Rehabilitation Court.  This discretion includes the authority to address Segregated Account obligations without the agreement 
of Ambac Assurance or its board of directors.  Moreover, even if the Segregated Account Rehabilitation Proceedings could be brought to a 
successful conclusion, there can be no assurance that any level of capital deemed sufficient by OCI to permit such conclusion will be sufficient 
to cover all future losses, whether currently anticipated or unanticipated.

The execution of Ambac’s strategy to actively runoff of Ambac Assurance and its subsidiaries is subject to the authority of the Rehabilitator 
(as defined below) to control the management of the Segregated Account. In exercising such authority, the Rehabilitator will act for the benefit 
of policyholders, and will not take into account the interests of Ambac.  The Rehabilitator's authority includes, but is not limited to, sole 
discretion over the rate at which the Segregated Account pays claims and the accretion rate on Deferred Amounts.  Similarly, by operation of 
the contracts executed in connection with the establishment, and subsequent rehabilitation, of the Segregated Account, the Rehabilitator retains 
rights to oversee and approve certain actions taken by or in respect of Ambac Assurance. Accordingly, oversight by the Rehabilitator could 
impair Ambac’s ability to execute certain of its strategies. Ambac Assurance's ability to commute policies or purchase certain investments 
may also be limited by available liquidity.  Opportunities for transaction terminations, policy commutations, settlements and restructurings 
also depend on market conditions, including the perception of Ambac Assurance’s creditworthiness, the structure of the underlying risk and 
associated policy as well as other counterparty specific factors.  

Although we are exploring selective business transactions that may permit utilization of Ambac’s tax net operating loss carry-forwards, such 
as the acquisition or development of new businesses or assets, no assurance can be given that we will be able to execute any such transactions.  
In addition, there can be no assurance that we will be able to obtain the financial and other resources that may be required to finance such 
transactions. Due to these factors, as well as uncertainties relating to the ability of Ambac Assurance to deliver value to Ambac, the value of 
our securities is speculative.  

As discussed in the Segregated Account of Ambac Assurance Corporation section below, the Rehabilitator has modified Ambac’s original 
policy obligations allocated to the Segregated Account under the Rehabilitation Plan such that policyholders receive cash for a portion of their 
claims and the right to receive Deferred Amounts on the unpaid balance of their claims. Such Deferred Amounts will be paid at the sole 
discretion of the Rehabilitator.  Furthermore, management’s ability to execute transactions to conclude the Rehabilitation Proceedings is also 
subject to the sole discretion of the Rehabilitator.   As a result of uncertainties associated with the oversight by the Rehabilitator of the Segregated 
Account, management has concluded that there is substantial doubt about Ambac's ability to continue as a going concern within one year after 
the date the financial statements are issued. Ambac’s financial statements as of and for the periods ending December 31, 2016 and 2015, 
respectively, are prepared assuming Ambac continues as a going concern and do not include any adjustment that might result from its inability 
to continue as a going concern.

Chapter 11 Reorganization of Ambac: 

The Reorganization Plan reflects a resolution of certain issues (the “Amended Plan Settlement”) among the Company, the statutory committee 
of creditors appointed by the United States Trustee on November 17, 2010 (the “Creditors’ Committee”), Ambac Assurance, the Segregated 
Account and OCI related to (i) the net operating loss carry forwards (“NOLs”) of the consolidated tax group of which the Company is the 
parent and Ambac Assurance is a member (the “Ambac Consolidated Group”), (ii) certain tax refunds received in respect thereof and (iii) the 
sharing of expenses between the Company and Ambac Assurance. The terms of the Amended Plan Settlement are memorialized in that certain 
Mediation Agreement dated September 21, 2011 (the “Mediation Agreement”) among such parties. In accordance with the Amended Plan 
Settlement, the Company shall use its best efforts to preserve the use of NOLs as contemplated by the Amended Plan Settlement. 

Pursuant to the Amended Plan Settlement, (i) the Company, Ambac Assurance and certain affiliates entered into an amended and restated tax 
sharing agreement (the “Amended TSA”), (ii) the Company, Ambac Assurance and certain affiliates entered into an expense sharing and cost 
allocation agreement (the “Cost Allocation Agreement”) and (iii) the Company, Ambac Assurance, the Segregated Account and OCI entered 
into an amendment of the Cooperation Agreement (as defined below) (the “Cooperation Agreement Amendment”). 

The Amended TSA addresses certain intercompany tax issues including, but not limited to, the allocation and use of NOLs by the Company, 
Ambac Assurance and their respective subsidiaries.  Refer to Note 15. Income Taxes for further discussion of the Amended TSA.

The Cost Allocation Agreement provides for the allocation of costs and expenses among the Company, Ambac Assurance and certain affiliates. 
Additionally, the Cost Allocation Agreement requires Ambac Assurance to reimburse reasonable operating expenses incurred by the Company, 
subject to an annual $5,000 limit until March 2017.  From March 2017 such expense reimbursement provision can be extended in the sole 
discretion of the rehabilitator subject to a $4,000 per year limit. 

The Cooperation Agreement Amendment provides for the Rehabilitator to have certain rights as described below. 

Segregated Account of Ambac Assurance Corporation:

In March 2010, Ambac Assurance established a Segregated Account pursuant to Wisc. Stat. §611.24 (2) (the “Segregated Account”) to segregate 
certain segments of Ambac Assurance’s liabilities, and the Office of the Commissioner of Insurance for the State of Wisconsin (“OCI” (which 
term shall be understood to refer to such office as regulator of Ambac Assurance and to refer to the Commissioner of Insurance for the State

of Wisconsin as rehabilitator of the Segregated Account (the “Rehabilitator”), as the context requires)) commenced rehabilitation proceedings 
in the Dane County, Wisconsin Circuit Court (the “Rehabilitation Court”) with respect to the Segregated Account (the “Segregated Account 
Rehabilitation Proceedings”) in order to permit OCI to facilitate an orderly run-off and/or settlement of the liabilities allocated to the Segregated 
Account pursuant to the provisions of the Wisconsin Insurers Rehabilitation and Liquidation Act. Net par exposure as of December 31, 2016
for policies allocated to the Segregated Account was $11,884,751.  Policy obligations not allocated to the Segregated Account remain in the 
General Account of Ambac Assurance, and such policies in the General Account are not subject to and, therefore, are not directly impacted 
by the Segregated Account Rehabilitation Plan (as defined below).

The Segregated Account is operated in accordance with a plan of operation (the “Plan of Operation”) and certain operative documents relating 
thereto (which include the Secured Note (defined below), the Reinsurance Agreement (defined below), the Management Services Agreement, 
dated as of March 24, 2010, by and between the Segregated Account and Ambac Assurance (the “Management Services Agreement”), the 
Cost Allocation Agreement and the Cooperation Agreement, dated as of March 24, 2010, by and between the Segregated Account and Ambac 
Assurance,  as  amended  pursuant  to  the  Cooperation Agreement Amendment  (the  “Cooperation Agreement”).  Pursuant  to  such  operative 
documents, Ambac Assurance entered into certain covenants for the benefit of the Segregated Account as described below. 

Pursuant to the Plan of Operation, Ambac Assurance allocated to the Segregated Account (1) certain policies insuring or relating to credit 
default swaps; (2) residential mortgage-backed securities (“RMBS”) policies; (3) certain policies insuring debt obligations backed by student 
loans; and (4) other policies insuring obligations with substantial projected impairments or relating to transactions which have contractual 
triggers based upon Ambac Assurance’s financial condition or the commencement of rehabilitation, which triggers are potentially damaging 
(collectively, the “Segregated Account Policies”). The policies described in (4) above include (a) certain types of securitizations, including 
commercial asset-backed transactions, consumer asset-backed transactions and other types of structured transactions; (b) the policies relating 
to Las Vegas Monorail Company; (c) policies relating to debt securities purchased by, and the debt securities issued by, Juneau Investments, 
LLC (“Juneau”), which is a finance company owned by Ambac Assurance and allocated to the Segregated Account as described below; 
(d) policies  relating  to  leveraged  lease  transactions;  and  (e) certain  policies  relating  to  interest  rate  and  other  swap  transactions. Ambac 
Assurance also allocated the following to the Segregated Account: (i) all remediation claims, defenses, offsets, and/or credits (except with 
respect to recoveries arising from remediation efforts or reimbursement or collection rights), if any, in respect of the Segregated Account 
Policies, (ii) Ambac Assurance’s limited liability interests in ACP, Ambac Conduit Funding LLC and Juneau and (iii) all of Ambac Assurance’s 
liabilities as reinsurer under reinsurance agreements (except for reinsurance assumed from Everspan).

In 2010, Ambac Assurance issued a $2,000,000 secured note due in 2050 (the “Secured Note”) to the Segregated Account. Interest on the 
Secured Note accrued at the rate of 4.5% per annum, and accrued interest was capitalized and added to outstanding principal quarterly. The 
Segregated Account had the ability to demand payment under the Secured Note from time to time to pay claims and other liabilities. In 2014, 
the Secured Note, including capitalized interest since the date of issuance, was fully drawn. Following the exhaustion of the Secured Note, 
the Segregated Account has the ability to demand payment from time to time under an aggregate excess of loss reinsurance agreement provided 
by Ambac Assurance (the “Reinsurance Agreement”) to pay claims and other liabilities. In addition, certain operating and administrative costs 
and expenses of the Segregated Account are now reimbursable by Ambac Assurance pursuant to the Cooperation Agreement. Ambac Assurance 
secured its obligations under the Secured Note and the Reinsurance Agreement by granting to the Segregated Account a security interest in 
all  of Ambac Assurance’s  right,  title  and  interest  in  (i) installment  premiums  received  in  respect  of  the  Segregated Account  Policies; 
(ii) reinsurance premiums received in respect of assumed reinsurance agreements with respect to which the liabilities of Ambac Assurance 
have been allocated to the Segregated Account; (iii) recoveries under third party reinsurance agreements in respect of the Segregated Account 
Policies; and (iv) any recoveries arising from remediation efforts or reimbursement or collection rights with respect to policies allocated to 
the Segregated Account.

Ambac Assurance is not obligated to make payments under the Reinsurance Agreement or Cooperation Agreement if its surplus as regards to 
policyholders is less than $100,000 (the “Minimum Surplus Amount”). As long as the surplus as regards to policyholders is not less than the 
Minimum Surplus Amount, payments by Ambac Assurance to the Segregated Account under the Reinsurance Agreement and Cooperation 
Agreement are not capped.  At December 31, 2016 and 2015, Ambac Assurance’s surplus as regards to policyholders exceeds the Minimum 
Surplus Amount.  In the event that Ambac Assurance does not maintain surplus in excess of the Minimum Surplus Amount, the Segregated 
Account would experience a shortfall in funds available to pay its liabilities. Any such shortfall would be a consideration for the Rehabilitator 
in the determination of whether any changes to the Segregated Account Rehabilitation Plan (as defined above) and/or the amount of partial 
policy claim payments are necessary or appropriate or whether to institute general rehabilitation proceedings against Ambac Assurance. 

During the Segregated Account Rehabilitation Proceedings, the Rehabilitator controls the management of the Segregated Account and possesses 
ultimate decision-making authority with respect to all matters relating to the policies allocated to the Segregated Account. Ambac Assurance 
provides certain management and administrative services to the Segregated Account and the Rehabilitator pursuant to the Management Services 
Agreement, including information technology services, credit exposure management, treasury, accounting, tax, management information, risk 
management,  loss  management,  internal  audit  services  and  business  continuity  services.  Services  are  provided  at  cost,  subject  to  mutual 
agreement of the Segregated Account and Ambac Assurance. Either party may terminate the Management Services Agreement for cause upon 
120 days written notice (or such shorter period as the Rehabilitator may determine) and the Segregated Account may terminate without cause 
at any time upon at least 30 days prior notice. If the Segregated Account elects to terminate the Management Services Agreement, Ambac 
Assurance will not have the right to consent to the replacement services provider.

(Dollar Amounts in Thousands, Except Share Amounts)

Pursuant to the Secured Note and the Reinsurance Agreement, Ambac Assurance has made certain covenants to the Segregated Account, 
including covenants that Ambac Assurance will not, (i) without the Segregated Account’s consent (not to be unreasonably withheld), amend 
its investment policies if doing so would have a material adverse effect on Ambac Assurance’s ability to perform its obligations under the 
Secured Note, the Reinsurance Agreement and the documents relating thereto or under any other material agreement to which it is a party, (ii) 
without the prior approval of the OCI, directly or indirectly make any distribution to its shareholder or redeem any of its securities and, (iii) 
without the Segregated Account’s consent (not to be unreasonably withheld), enter into any transaction other than pursuant to the reasonable 
requirements of Ambac Assurance’s business and which Ambac Assurance reasonably believes are fair and reasonable terms and provisions.

Pursuant to the Cooperation Agreement, Ambac Assurance and the Segregated Account have agreed to certain matters related to decision-
making,  information  sharing,  tax  compliance  and  allocation  of  expenses,  including  an  agreement  by Ambac Assurance  to  reimburse  the 
Segregated Account for specified expenses, subject to the Minimum Surplus Amount. Ambac Assurance has made certain covenants to the 
Segregated Account pursuant to the Cooperation Agreement, including an agreement to not enter into any transaction involving consideration 
or other proceeds of more than $5,000 (or such higher amount as determined by the Rehabilitator) without the Segregated Account’s prior 
written  consent  (other  than  policy  claim  payments  made  in  the  ordinary  course  of  business  and  investments  in  accordance  with Ambac 
Assurance’s investment policy), and providing the Segregated Account with an annual operating expense budget for Ambac Assurance and 
its subsidiaries, as well as quarterly analyses of variances. The Cooperation Agreement also addresses Ambac Assurance’s rights in the event 
Ambac Assurance is no longer the management and administrative services provider to the Segregated Account as described above. The 
Cooperation Agreement Amendment made each of the Company and the Rehabilitator a party to the Cooperation Agreement and provides the 
Rehabilitator with certain additional approval rights with respect to (a) the tax positions taken by the Company in its consolidated tax return; 
(b) the acceptance by Ambac Assurance of the repayment of intercompany loans or the modification of the terms thereof; (c) changes by 
Ambac Assurance in the assumptions or vendors utilized in determining loss reserves determined in accordance with Statutory Accounting 
Principles; and (d) changes to Ambac Assurance’s investment policy and transfer of the investment management function for Ambac Assurance’s 
investment portfolio.

On October 8, 2010, OCI filed a plan of rehabilitation for the Segregated Account (the “Segregated Account Rehabilitation Plan”) in the 
Rehabilitation Court. The Rehabilitation Court confirmed the Segregated Account Rehabilitation Plan on January 24, 2011, although it did 
not become effective at such time. The confirmed Segregated Account Rehabilitation Plan also made permanent the injunctions issued by the 
Rehabilitation Court on March 24, 2010. On June 4, 2012, the Rehabilitation Court approved a motion made by the Rehabilitator to make 
partial  interim  policy  claim  payments  to  Segregated Account  policyholders.  In  accordance  with  such  approval,  on August  1,  2012,  the 
Rehabilitator promulgated Rules Governing the Submission, Processing and Partial Payment of Policy Claims in accordance with the June 4, 
2012 Interim Cash Payment Order (the “Policy Claim Rules”). Pursuant to the Policy Claim Rules, effective from August 1, 2012, holders of 
policies allocated to the Segregated Account were allowed to submit policy claims for review and partial payment equating to 25% of the 
permitted policy claim amount, and on or about September 20, 2012, the Segregated Account commenced paying 25% of each permitted 
policy claim that arose since the commencement of the Segregated Account Rehabilitation Proceedings.

On July 11, 2013 the Rehabilitator filed a motion with the Rehabilitation Court seeking approval from the Rehabilitation Court for the Segregated 
Account to make cash payments in excess of 25% of the permitted policy claim amount (“Supplemental Payments”) with respect to certain 
policies (the “SP Policies”) so that cash flow in the related securitization trusts that would have been available to reimburse Ambac Assurance 
had it paid claims in full under such policies is not diverted to uninsured holders who would not have received such cash flow if claims had 
been paid in full. Without making such Supplemental Payments, Ambac Assurance would likely realize lower levels of reimbursements and 
subrogation recoveries as cash flow that would have been available for the benefit of Ambac Assurance in relation to the SP Policies would 
be lost to such uninsured holders. A hearing on such motion was held on August 2, 2013, following which the Rehabilitation Court granted 
such motion and entered an order permitting Supplemental Payments to be made with respect to the SP Policies. As a result, the Segregated 
Account has been making Supplemental Payments on SP Policies since August 2013.  On February 13, 2014, the Rehabilitator also received 
approval  from  the  Rehabilitation  Court  for  the  Rehabilitator  and  the  Segregated Account  to  disburse  settlement  proceeds  from  RMBS 
remediation claims as permitted policy claim payments, with such distributions to include (i) paying claims payments in excess of the then 
applicable claims cash payment percentage, and/or (ii) paying all or portions of unpaid permitted policy claims (such policy claim payments, 
“Special Policy Payments”).

On January 17, 2014, the Rehabilitator filed a motion to obtain court approval to disburse settlement proceeds as permitted policy claim 
payments to specific policyholders as required by a settlement entered into with Residential Capital, LLC and related debtors in bankruptcy 
proceedings in the U.S. Bankruptcy Court for the Southern District of New York (the “ResCap Settlement”). In addition to seeking this approval 
with respect to the ResCap Settlement, the motion sought the court’s confirmation of the Rehabilitator’s authority to distribute proceeds from 
settlements of RMBS remediation claims as he deems appropriate and in the best interests of the Segregated Account and such distributions 
may include (i) paying claims by making payments in excess of the then applicable claims cash payment percentage, and/or (ii) paying all or 
portions of unpaid permitted policy claims. On February 7, 2014, three RMBS trustees jointly filed a partial objection to the motion. On 
February 13, 2014, the Rehabilitation Court heard argument on this motion and issued an order approving the Rehabilitator’s motion.

On June 11, 2014, the Rehabilitation Court approved amendments to the Segregated Account Rehabilitation Plan that had been proposed by 
the Rehabilitator, and the Segregated Account Rehabilitation Plan, as amended, became effective on June 12, 2014. The amendments to the 
Segregated Account Rehabilitation Plan primarily modified the mechanism for handling claims. Instead of the combination of cash payments

and interest-bearing surplus notes originally contemplated by the Segregated Account Rehabilitation Plan, under the amended Segregated 
Account Rehabilitation Plan holders of permitted policy claims have received and will receive an initial interim cash payment for a portion 
of such policy claim (“Interim Payment”), together with the right to receive a deferred payment equal to the balance of the unpaid policy 
claim, as may be adjusted from time to time pursuant to the terms of the amended Segregated Account Rehabilitation Plan (“Deferred Amount”). 
Payments of Deferred Amounts will be made at such times as the Rehabilitator deems appropriate in his sole discretion. The Segregated 
Account will also establish junior deferred amounts (“Junior Deferred Amounts”) with respect to permitted general claims instead of issuing 
junior surplus notes to the holders of such claims as contemplated under the original Segregated Account Rehabilitation Plan.

Under the amended Segregated Account Rehabilitation Plan, Deferred Amounts and Junior Deferred Amounts generally accrue and compound 
interest at an annual effective rate of 5.1%. However, in the case of insured bonds whose outstanding principal balance is not reduced by the 
unpaid portion of permitted policy claims (such bonds, “Undercollateralized Bonds”), the 5.1% effective annual interest rate on the Deferred 
Amount will be reduced by the bond interest rate applicable to such Undercollateralized Bonds. In the case of permitted policy claims relating 
to transactions that pay monthly, interest will begin to accrue on Deferred Amounts from the first distribution date (under the transaction 
documents for the relevant bond) after the date on which the Interim Payment in respect of such permitted policy claim was made. For permitted 
policy claims relating to transactions that do not pay monthly, interest will begin to accrue on Deferred Amounts from the first Payment Date 
(as defined in the Segregated Account Rehabilitation Plan, as amended) to occur after the date on which the Interim Payment in respect of 
such permitted policy claim was made.

Following the effective date of the Segregated Account Rehabilitation Plan, as amended, the IPP for permitted policy claims increased from 
25% to 45% with effect from July 21, 2014. As with previously permitted policy claims, the remaining portion of the unpaid permitted policy 
claims (in this case, 55%) will remain outstanding as Deferred Amounts and, subject to the adjustment for Undercollateralized Bonds, will 
accrue interest at 5.1% per annum. These Deferred Amounts, together with interest thereon, may be paid from time to time in the future at the 
sole discretion of the Rehabilitator. As further described in Note 17. Commitments and Contingencies, on February 10, 2016, certain investors 
filed a motion in the Rehabilitation Court requesting an order directing the Rehabilitator to show cause why the Interim Payment percentage 
should not be substantially increased.  The motion was denied.

A portion of Deferred Amounts outstanding as of July 20, 2014 (the “Reconciliation  Date”) (together with interest thereon), if still outstanding, 
was paid on December 22, 2014 (the "Deferred Payment Date") in accordance with the Segregated Account Rehabilitation Plan, as amended, 
such that those policyholders that received 25% (and not 45%) cash Interim Payments in respect of their permitted policy claims were generally 
entitled to receive equalizing payments in cash of 26.67% of their Deferred Amounts (including accrued interest thereon) outstanding as of 
the Reconciliation Date. Policyholders were entitled to receive an equalizing payment of their Deferred Amounts equal to the lower of (i) their 
outstanding Deferred Amounts on December 22, 2014, and (ii) 26.67% of their Deferred Amounts as of the Reconciliation Date, even if they 
had received a Supplemental Payment and/or a Special Policy Payment.  The aggregate amount of equalizing payments for Deferred Amounts 
(including interest thereon) paid on the Deferred Payment Date was $1,137,202.

In addition, the Segregated Account was required, pursuant to the terms of the amended Segregated Account Rehabilitation Plan, to early 
redeem a portion of its surplus notes (excluding junior surplus notes) on or about the Deferred Payment Date. The redemption amount of the 
Segregated Account surplus notes was equal to 26.67% of the sum of par and accrued interest on such Segregated Account surplus notes, in 
each case, outstanding as at the Reconciliation Date.  Pursuant to the terms of the Settlement Agreement, Ambac Assurance is also required 
to make a proportionate redemption of its surplus notes when the Segregated Account redeems Segregated Account surplus notes (excluding 
junior surplus notes).  Therefore, the Segregated Account and Ambac Assurance were both required to make redemptions of surplus notes 
(excluding any junior surplus notes) on or about the Deferred Payment Date in an amount equal to 26.67% of the sum of par and accrued 
interest outstanding on such surplus notes as at the Reconciliation Date, which was $413,587 in respect of those surplus notes owned by third 
parties. Ambac Assurance, for and on behalf of itself and as the management services provider for the Segregated Account, sought and received 
the approval of the Commissioner of Insurance of the State of Wisconsin to effect these redemptions of surplus notes on November 20, 2014, 
rather than the Deferred Payment Date, to save interest expense. Such approval was granted on October 13, 2014. 

On July 12, 2016, the Special Deputy Commissioner ("SDC") for the Segregated Account met with policy beneficiaries and holders of surplus 
notes of Ambac Assurance and the Segregated Account during which the SDC stated (i) that at present, the Rehabilitator does not have any 
plans to increase the interim payment percentage (“IPP”) on Segregated Account policy claims, commenting that the Rehabilitator and his 
advisors  would  need  to  feel  highly  confident  that  any  change  to  the  IPP  would  be  sustainable  and  fair  to  all  policyholders;  (ii)  that  the 
Rehabilitator reserves the right to amend the Segregated Account Rehabilitation Plan or take such other action as he deems necessary or 
appropriate to adjust the rate of accretion on Deferred Amounts from time to time based on such factors as he considers relevant and, as such, 
the accretion rate remains under review; and (iii) his objective of seeking an exit of the Segregated Account from rehabilitation, and further 
stated that although his preferred goal would be to achieve an exit from rehabilitation through a consensual plan, he would advise the Rehabilitator 
to use all tools available to accomplish a successful and durable conclusion that enhances Ambac Assurance's long-term claims-paying ability.

On December 16, 2016, the Rehabilitator filed with the Rehabilitation Court a supplement to his 2016 Annual Report dated June 1, 2016 
relating to the Segregated Account Rehabilitation Proceedings (the “Supplement”). In the Supplement, the Rehabilitator reiterated his goal of 
achieving a successful and durable conclusion to the Segregated Account Rehabilitation Proceedings. The Rehabilitator also stated in the 
Supplement that at  the  present  time and absent  further  actions,  Ambac Assurance has  insufficient  capital  to  demonstrate to the satisfaction

(Dollar Amounts in Thousands, Except Share Amounts)

of the Rehabilitator that the Segregated Account Rehabilitation Proceedings could be concluded  and leave Ambac Assurance with sufficient 
financial resources to  meet  all policy  obligations,  as  projected  by  the  Rehabilitator  (in  his  sole  discretion)  under  a  varying  range  of  
base  and  stress  case  scenarios.   The Rehabilitator further stated in the Supplement that given such requirements,  any transaction facilitating 
the conclusion of the Segregated Account Rehabilitation Proceedings will  need  to  provide  for  an  increase  in  Ambac Assurance’s  existing  
surplus  capital, as determined and defined by OCI in its sole discretion. We cannot provide assurance that the terms of any possible transaction 
will satisfy OCI or the Rehabilitator that Ambac Assurance has, or will have, sufficient capital to meet all policy obligations after the conclusion 
of the Segregated Account Rehabilitation Proceedings.

United Kingdom Referendum

In a non-binding referendum on the United Kingdom’s (“UK”) membership in the European Union in June 2016, a majority of those who 
voted approved the UK’s withdrawal from the European Union (“EU”). A withdrawal by the UK from the European Union (“Brexit”) may 
occur after, or possibly concurrently with, a process of negotiation regarding the future terms of the UK’s relationship with the EU, which 
could result in the UK losing access to certain aspects of the single EU market and the global trade deals negotiated by the EU on behalf of 
its members. The Brexit vote and the perceptions as to the impact of the withdrawal of the UK may adversely affect business activity, political 
stability and economic conditions in the UK, the Eurozone, the EU and elsewhere. The economic outlook could be adversely affected by (i) 
the risk that one or more other EU countries could come under increasing pressure to leave the EU, (ii) the risk of a greater demand for 
independence by Scottish nationalists or for unification in Ireland, or (iii) the risk that the Euro as the single currency of the Eurozone could 
cease to exist. Any of these developments, or the perception that any of these developments are likely to occur, could have a material adverse 
effect on economic growth or business activity in the UK, the Eurozone, or the EU, and could result in the relocation of businesses, cause 
business interruptions, lead to economic recession or depression, and impact the stability of the financial markets, the availability of credit, 
political systems or financial institutions and the financial and monetary system.  Consequently the medium and longer term impact on the 
UK generally, and Ambac Assurance UK Limited ("Ambac UK") specifically, is uncertain.  The immediate impact on the UK included a 
decline in the value of the British Pound against major currencies and greater asset volatility. 

2.        BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES 

Ambac’s consolidated financial statements have been prepared on the basis of U.S. generally accepted accounting principles (“GAAP”). The 
preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported 
amounts  of  assets,  liabilities,  revenues,  expenses  and  disclosures  of  contingent  assets  and  liabilities.  Such  estimates  that  are  particularly 
susceptible to change are used in connection with certain fair value measurements, the evaluation of other than temporary impairments on 
investments, loss reserves for non-derivative insurance policies, the evaluation of the need for an impairment of goodwill or valuation allowance 
on the deferred tax asset, any of which individually could be material. 

Consolidation: 

The consolidated financial statements include the accounts of Ambac and all other entities in which Ambac (directly or through its subsidiaries) 
has a controlling financial interest, including variable interest entities (“VIEs”) for which Ambac or an Ambac subsidiary is deemed the primary 
beneficiary in accordance with the Consolidation Topic of the Accounting Standards Codification ("ASC"). All significant intercompany 
balances have been eliminated. The usual condition for a controlling financial interest is ownership of a majority of the voting interests of an 
entity. However, a controlling financial interest may also exist in entities, such as VIEs, through arrangements that do not involve controlling 
voting interests. The primary beneficiary of a VIE is the party that has both the following characteristics: a) the power to direct the activities 
of the VIE that most significantly impact the VIE’s economic performance and b) the obligation to absorb losses of the VIE that could potentially 
be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. An entity that is deemed 
the primary beneficiary of a VIE is required to consolidate the VIE. 

A VIE is an entity: a) that lacks enough equity investment at risk to permit the entity to finance its activities without additional subordinated 
financial support from other parties; or b) where the group of equity holders does not have: (1) the power, through voting rights or similar 
rights, to direct the activities of an entity that most significantly impact the entity’s economic performance; (2) the obligation to absorb the 
entity’s expected losses; or (3) the right to receive the entity’s expected residual returns. The determination of whether a variable interest holder 
is  the  primary  beneficiary  involves  performing  a  qualitative  analysis  of  the VIE  that  includes,  among  other  factors,  its  capital  structure, 
contractual terms including the rights of each variable interest holder, the activities of the VIE, whether the variable interest holder has the 
power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, whether the variable interest holder 
has the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that 
could potentially be significant to the VIE, related party relationships and the design of the VIE. Refer to Note 3. Special Purpose Entities, 
Including Variable Interest Entities, for a detailed discussion of Ambac’s involvement in VIEs, Ambac’s methodology for determining whether 
Ambac is required to consolidate a VIE and the effects of VIEs being consolidated. 

Ambac Unconsolidated Financial Information: 

Financial information of Ambac is presented in Schedule II to this Form 10-K as of December 31, 2016 and 2015 and for the years ended 
December 31, 2016, 2015 and 2014. Investments in subsidiaries are accounted for using the equity method of accounting.

Investments: 

The Investments - Debt and Equity Securities Topic of the ASC requires that all debt instruments and certain equity instruments be classified 
in Ambac’s Consolidated Balance Sheets according to their purpose and, depending on that classification, be carried at either cost or fair 
market value. Ambac’s non-VIE investment portfolio is accounted for on a trade-date basis and consists primarily of investments in fixed 
income securities that are considered available-for-sale as defined by the Investments - Debt and Equity Securities Topic of the ASC. Available-
for-sale securities are reported in the financial statements at fair value with unrealized gains and losses, net of deferred taxes, reflected in 
Accumulated Other Comprehensive Income in Stockholders’ Equity and computed using amortized cost as the basis. For purposes of computing 
amortized cost, premiums and discounts are accounted for using the effective interest method over the remaining term of the securities. For 
structured securities with a large underlying pool of homogenous loans, such as mortgage-backed and asset-backed securities, premiums and 
discounts  are adjusted for the effects of actual and anticipated prepayments on a retrospective basis. For other fixed income securities, such 
as corporate and municipal bonds, premiums and discounts are amortized or accreted over the remaining term of the securities even if they 
are callable. 

Ambac’s investment portfolio also includes equity interests in pooled investment funds. Such equity interests in the form of common stock 
or in-substance common stock are classified as trading securities. Equity interests in pooled funds organized as limited liability companies 
are recorded under the fair value option in accordance with the Financial Instruments Topic of the ASC Topic 825. Investments classified 
either as trading or fair value option securities are reported as Other investments on the Consolidated Balance Sheet at fair value with changes 
in fair value reported through Net investment income on the Statement of Comprehensive Income. Investments in pooled funds have been 
classified as trading or fair value option securities so that any undistributed earnings of the funds may be reflected in Net investment income 
as they occur. 

Fair value is based primarily on quotes obtained from independent market sources. When quotes are not available or cannot be reasonably 
corroborated, valuation models are used to estimate fair value. These models include estimates, made by management, which utilize current 
market information. The quotes received or modeled valuations could differ materially from amounts that would actually be realized in the 
market. Realized gains and losses on the sale of investments are determined on the basis of specific identification. 

VIE investments in fixed income securities are carried at fair value under the fair value option. For additional information about VIE investments, 
including fair value by asset-type, see Note 3. Special Purpose Entities, Including Variable Interest Entities. 

Ambac has a formal impairment review process for available for sale securities in its investment portfolio. Ambac conducts a review each 
quarter to identify and evaluate investments that have indications of impairment that may be other than temporary in accordance with the 
Investments - Debt and Equity Securities Topic of the ASC. Factors considered to identify and assess securities for other than temporary 
impairment include: (i) fair values that have declined by 20% or more below amortized cost; (ii) market values that have declined by 5% or 
more but less than 20% below amortized cost for a continuous period of at least six months; (iii) recent downgrades by rating agencies; (iv) the 
financial condition of the issuer and financial guarantor, as applicable, and an analysis of projected defaults on the underlying collateral; 
(v) scheduled interest payments are past due; (vi) whether Ambac has the intent to sell the security; and (vii) whether it is more likely than 
not that Ambac will be required to sell a security  before the anticipated recovery of its amortized cost basis. If we believe a decline in the fair 
value of a particular investment is temporary, we record the decline as an unrealized loss net of tax in Accumulated Other Comprehensive 
Income in Stockholders’ Equity on our Consolidated Balance Sheets. If management either: (i) has the intent to sell its investment in a debt 
security or (ii) determines that the Company more likely than not will be required to sell the debt security before its anticipated recovery of 
the amortized cost basis less any current period credit impairment, then an other-than-temporary impairment charge is recognized in earnings, 
with the amortized cost of the security being written-down to fair value. If these conditions are not met, but it is determined that a credit loss 
exists, the credit impairment loss is recognized in earnings, and the other-than-temporary amount related to all other factors is recognized in 
other comprehensive income. For fixed income securities that have other-than-temporary impairments in a period, the previous amortized cost 
of the security less the amount of the other-than-temporary impairment recorded through earnings becomes the investment’s new cost basis. 
Ambac accretes the new cost basis to par or to the estimated future cash flows to be recovered over the expected remaining life of the security. 

The evaluation of securities for impairment is a quantitative and qualitative process, which is subject to risks and uncertainties and is intended 
to determine whether, and to what extent, declines in the fair value of investments should be recognized in current period earnings. The risks 
and uncertainties include changes in general economic conditions, the issuer’s or guarantor’s financial condition and/or future prospects, the 
impact of regulatory actions on the investment portfolio, the performance of the underlying collateral, the effects of changes in interest rates 
or credit spreads and the expected recovery period.  With respect to Ambac insured securities owned, future cash flows used to measure credit 
impairment represents the sum of (i) the bond’s intrinsic cash flows and (ii) the estimated Ambac Assurance claim payments. For Ambac-
insured securities owned and guaranteed under policies allocated to the Segregated Account, the estimate of Ambac Assurance claim payments 
includes interest on Deferred Amounts. Ambac estimates the timing of claim payment receipts on all Ambac-insured securities owned, but the 
actual timing of such amounts for Segregated Account securities are at the sole discretion of the Rehabilitator.  Further modifications to the 
Segregated Account Rehabilitation Plan or to the rules and guidelines promulgated thereunder, orders from the Rehabilitation Court or actions 
by the Rehabilitator with respect to the form, amount and timing of satisfying permitted policy claims, or making payments on Deferred 
Amounts or surplus notes, may have a material effect on the fair value of Segregated Account securities and future recognition of other-than-
temporary impairments.  Refer to Note 1. Background and Business Description for information relating to the amended Segregated Account

Rehabilitation Plan. Ambac’s assessment about whether a decline in value is other-than-temporary reflects management’s current judgment 
regarding facts and circumstances specific to a security and the factors noted above, including Ambac's intention to sell securities and ability 
to hold temporarily impaired securities until recovery. If that judgment changes, Ambac may ultimately record a charge for other-than-temporary 
impairment in future periods.

Net Premiums: 

Gross premiums are received either upfront or in installments. For premiums received upfront, an unearned premium revenue (“UPR”) liability 
is established, which is initially recorded as the cash amount received. For installment premium transactions, a premium receivable asset and 
offsetting UPR liability is initially established in an amount equal to: (i) the present value of future contractual premiums due (the “contractual” 
method) or (ii) if the underlying insured obligation is a homogenous pool of assets which are contractually prepayable, the present value of 
premiums to be collected over the expected life of the transaction (the “expected” method). An appropriate risk-free rate corresponding to the 
weighted average life of each policy and currency is used to discount the future premiums contractually due or expected to be collected. For 
example, U.S. dollar exposures are discounted using U.S. Treasury rates while exposures denominated in a foreign currency are discounted 
using the appropriate risk-free rate for the respective currency. The weighted average risk-free rate at December 31, 2016 and 2015, was 2.6%. 
and 2.7%, respectively, and the weighted average period of future premiums used to estimate the premium receivable at December 31, 2016 
and 2015, was 9.0 years and 9.2 years, respectively.

Insured obligations consisting of homogeneous pools for which Ambac uses expected future premiums to estimate the premium receivable 
and UPR include residential mortgage-backed securities. As prepayment assumptions change for homogenous pool transactions, or if there is 
an actual prepayment for a “contractual” method installment transaction, the related premium receivable and UPR are adjusted in equal and 
offsetting amounts with no immediate effect on earnings using new premium cash flows and the then current risk-free rate corresponding to 
the initial weighted average life of the related policy.

For both upfront and installment premium policies, premium revenues are earned over the life of the financial guarantee contract in proportion 
to the insured principal amount outstanding at each reporting date (referred to as the level-yield method). For installment paying policies, the 
premium receivable discount, equating to the difference between the undiscounted future installment premiums and the present value of future 
installment premiums, is accreted as premiums earned in proportion to the premium receivable balance at each reporting date. 

Similar to gross premiums, premiums ceded to reinsurers are paid either upfront or in installments. For premiums paid upfront, a deferred 
ceded premium asset is established which is initially recorded as the cash amount paid. For installment premiums, a ceded installment premiums 
payable liability and offsetting deferred ceded premium asset are initially established in an amount equal to: i) the present value of future 
contractual premiums due or ii) if the underlying insured obligation is a homogenous pool of assets which are contractually pre-payable, the 
present value of expected premiums to be paid over the life of the transaction. An appropriate risk-free rate corresponding to the weighted 
average life of each policy and exposure currency is used to discount the future premiums contractually due or expected to be collected. 
Premiums ceded to reinsurers reduce the amount of premiums earned by Ambac from its financial guarantee insurance policies. For both 
upfront and installment premiums, ceded premiums written are primarily recognized in earnings in proportion to and at the same time as the 
related gross premium revenue is recognized. For premiums paid to reinsurers on an installment basis, Ambac records the present value of 
future ceding commissions as an offset to ceded premiums payable, using the same assumptions noted above for installment premiums. 

When a bond issue insured by Ambac has been retired early, typically due to an issuer call, any remaining UPR is recognized at that time to 
the extent the financial guarantee contract is legally extinguished, causing accelerated premium revenue. For installment premium paying 
transactions, we offset the recognition of any remaining UPR by the reduction of the related premium receivable to zero (as it will not be 
collected as a result of the retirement), which may cause negative accelerated premium revenue. Certain obligations insured by Ambac have 
been legally defeased whereby government securities are purchased by the issuer with the proceeds of a new bond issuance, or less frequently 
with other funds of the issuer, and held in escrow. The principal and interest received from the escrowed securities are then used to retire the 
Ambac-insured obligations at a future date either to their maturity date (a refunding) or a specified call date (a pre-refunding). Ambac has 
evaluated the provisions in policies issued on these obligations and determined those insurance policies have not been legally extinguished.  
For policies with refunding securities, premium revenue recognition is not impacted as the escrowed maturity date is the same as the previous 
legal maturity date.  For policies with pre-refunding securities, the maturity date of the pre-refunded security has been shortened from its 
previous legal maturity.  Although premium revenue recognition has not been accelerated in the period of the pre-refunding, it results in an 
increase in the rate at which the policy's remaining UPR is to be recognized.

Loans: 

Loans are reported at either their outstanding principal balance less unamortized discount or at fair value. For loans reported at their outstanding 
principal balance less unamortized discount (non-VIE loans), interest income is earned using the effective interest method based upon interest 
accrued on the unpaid principal balance adjusted for accretion of discounts.  A loan is considered impaired when, based on the financial 
condition of the borrower, it is probable that Ambac will be unable to collect all principal and interest due according to the contractual terms 
of the loan agreement. Loans held by VIEs consolidated as required under the Consolidation Topic of the ASC are carried at fair value, with 
changes in fair value recorded in Income (loss) on variable interest entities on the Consolidated Statements of Total Comprehensive Income.

(Dollar Amounts in Thousands, Except Share Amounts)

Derivative Contracts: 

The Company has entered into derivative contracts both for trading purposes and to hedge certain economic risks inherent in its financial asset 
and liability portfolios.  None of Ambac’s derivative contracts are designated as hedges under the Derivatives and Hedging Topic of the ASC.  
Ambac's derivatives consist primarily of credit derivatives, interest rate swaps and futures contracts.  Ambac’s credit derivative contracts are 
accounted for at fair value since they do not qualify for the financial guarantee scope exception under the Derivatives and Hedging Topic of 
the ASC. Changes in fair value of credit derivatives are recorded in Net change in fair value of credit derivatives on the Consolidated Statements 
of Total Comprehensive Income.  Ambac maintains a derivatives portfolio consisting primarily of interest rate swaps and futures contracts to 
mitigate exposure to floating rate insured obligations in the financial guarantee portfolio.  This portfolio also includes legacy interest rate 
swaps with asset-backed securitization issuers, states, municipalities and their authorities which were written in connection with their financings.  
Changes in fair value of these interest rate derivatives are recorded in Derivative product revenue on the Consolidated Statements of Total 
Comprehensive Income. VIEs consolidated under the Consolidation Topic of the ASC entered into derivative contracts to meet specified 
purposes within their securitization structure. Changes in fair value of consolidated VIE derivatives are included within Income (loss) on 
variable interest entities on the Consolidated Statements of Total Comprehensive Income. 

All derivatives are recorded on the Consolidated Balance Sheets at fair value on a gross basis; assets and liabilities are netted by counterparty 
only when a legal right of offset exists. Ambac has determined that the amounts recognized for the right to reclaim cash collateral or the 
obligation to return cash collateral may not be used to offset amounts due under the derivative instruments in the normal course of settlement. 
Therefore, such amounts are not offset against fair value amounts recognized for derivative instruments executed with the same counterparty 
under the same master netting arrangement. Refer to Note 11. Derivative Instruments for further discussion of the Company’s use of derivative 
instruments and their impact of the consolidated financial statements. Refer to Note 9. Fair Value Measurements for further description of the 
methodologies used to determine the fair value of derivative contracts, including model inputs and assumptions where applicable. 

Goodwill: 

Under the Reorganization Topic of the ASC, the Company determined that fresh start financial statement reporting was to be applied upon 
our emergence from Chapter 11 because (i) the reorganization value of the emerging entity was less than total post-petition liabilities and 
allowed claims, and (ii) the holders of existing voting shares immediately before the confirmation of the Reorganization Plan received less 
than 50% of the voting shares of the emerging entity. Specifically, fresh start reporting was applied upon confirmation of the Reorganization 
Plan by the Bankruptcy Court and the satisfaction of the remaining material contingencies necessary to complete implementation of the 
Reorganization Plan. All conditions required for the adoption of fresh start reporting were satisfied by the Company on April 30, 2013 (“Fresh 
Start Reporting Date”) when Ambac executed a closing agreement with the United States Internal Revenue Service (the "IRS") to conclude 
the settlement of a dispute.  As such, fresh start financial statement reporting ("Fresh Start") was adopted by the Company on April 30, 2013, 
incorporating, among other things, the discharge of debt obligations, issuance of new common stock and fair value adjustments. At the Fresh 
Start Reporting Date, we revalued our assets and liabilities to current estimated fair value. The excess reorganization value which could not 
be attributed to the fair value of specific identified tangible and intangible assets ("fair value of net assets") was recorded as goodwill. Pursuant 
to the Intangibles - Goodwill and Other Topic of the ASC, goodwill is not amortized but is subject to annual impairment testing. 

We tested goodwill for impairment as of October 1st of each year. Goodwill is also tested more frequently if indicators of impairment exist 
for each reporting unit. During the third quarter of 2015, Ambac determined sufficient indicators of potential impairment existed to perform 
an interim goodwill impairment evaluation for the Financial Guarantee reporting unit. Those indicators included the trading values of Ambac 
stock and changes in Ambac credit spreads.  In conducting the goodwill impairment analysis, we performed step one of the goodwill impairment 
test for the Financial Guarantee reporting unit. We estimated the fair value of the Financial Guarantee reporting unit using a market approach, 
which was derived using: i) Ambac’s common stock and warrant market capitalization,  ii) fair value estimates of Ambac Assurance preferred 
shares (reported as noncontrolling interests on Ambac's balance sheet) and iii) an estimated control premium. Step one of the impairment test 
indicated the Financial Guarantee reporting unit's carrying value exceeded its fair value.

Accordingly, the Company performed step two of the impairment test, which indicated the implied fair value of goodwill was zero.  This was 
the result of  substantial decreases in the Financial Guarantee reporting unit's fair value and substantial increases in the fair value of its net 
assets.    The  fair  value  of  the  Financial  Guarantee  reporting  unit  decreased  significantly  due  to  a  material  decrease  in Ambac's  market 
capitalization components (described above).  The Financial Guarantee reporting unit's fair value of net assets increased significantly primarily 
as a result of a decrease in the estimated fair value of financial guarantee liabilities and, to a lesser extent, a decrease in the fair value of long-
term debt.  The fair value decrease in financial guarantee liabilities, which is a Level 3 estimate, was primarily driven by wider Ambac credit 
spreads and positive loss and loss expense reserves development.  Please refer to Note 9. Fair Value Measurements for further discussion on 
the fair value model for financial guarantee liabilities. The fair value decrease in long-term debt was driven by lower market pricing on surplus 
notes and junior surplus notes.

As a result, the Company recorded a full non-cash, non-tax deductible goodwill impairment charge of $514,511 in 2015.  The following is a 
summary of activity in goodwill that was all assigned to the Financial Guarantee reporting unit:

At the Fresh Start Reporting Date, an insurance intangible asset was recorded which represented the difference between the fair value and 
aggregate  carrying  value  of  the  financial  guarantee  insurance  and  reinsurance  assets  and  liabilities. The  carrying  values  of  our  financial 
guarantee insurance and reinsurance contracts will continue to be reported and measured in accordance with existing accounting policies. 
Pursuant to the Financial Services-Insurance Topic of the ASC, the insurance intangible is to be measured on a basis consistent with the related 
financial guarantee insurance and reinsurance contracts. The insurance intangible asset is amortized using a level yield method based on par 
exposure of the related financial guarantee insurance or reinsurance contracts and is applied to groups of contracts with similar characteristics. 

Restricted Cash: 

Cash that we do not have the right to use for general purposes is recorded as restricted cash in our consolidated balance sheets. Restricted cash 
includes consolidated variable interest entity cash restricted to fund the obligations of the consolidated VIEs. 

Loss and Loss Expenses: 

The loss and loss expense reserve (“loss reserve”) policy for financial guarantee insurance relates only to Ambac’s non-derivative insurance 
business for insurance policies issued to beneficiaries, including VIEs, for which we do not consolidate the VIE. Losses and loss expenses are 
based upon estimates of the ultimate aggregate losses inherent in the non-derivative financial guarantee portfolio as of the reporting date. The 
policy for derivative contracts is discussed in the “Derivative Contracts” section below. A loss reserve is recorded on the balance sheet on a 
policy-by-policy basis. Loss reserve components of an insurance policy include unpaid claims and the present value ("PV") of expected net 
cash flows required to be paid under an insurance contract, further described below:  

•  Unpaid claims represent the sum of (i) claims not yet paid for policies allocated to the Segregated Account, including Deferred Amounts 
(as defined in Note 1. Background and Business Description) and (ii) accrued interest on Deferred Amounts (generally at an effective 
rate of 5.1%.) as required by the amended Segregated Account Rehabilitation Plan that became effective on June 12, 2014.  Refer to 
Note 1. Background and Business Description for further discussion of the amended Segregated Account Rehabilitation Plan.  Unpaid 
claims are measured based on the cost of settling the claims, which is principal plus accrued interest.  

• 

The PV of expected net cash flows represents the PV of expected cash outflows less the PV of expected cash inflows. The PV of 
expected net cash flows are impacted by: (i) expected future claims to be paid under an insurance contract, including the impact of 
potential  settlement  outcomes  upon  future  installment  premiums,  (ii)  expected  recoveries  from  contractual  breaches  of  RMBS 
representations and warranties by transaction sponsors, (iii) excess spread within the underlying transaction's cash flow structure, and 
(iv) other subrogation recoveries. Expected receipts from third parties within the underlying transaction's cash flow structure relating 
to contractual breaches in non-RMBS securitizations may also reduce expected future claims. Ambac’s approach to resolving disputes 
involving contractual breaches by transaction sponsors or other third parties has included negotiations and/or pursuing litigation. Ambac 
does not include potential recoveries attributed solely to fraudulent inducement claims in our estimate of subrogation recoveries, since 
any remedies under such claims would be non-contractual.  

Net cash outflow policies represent contracts where the sum of unpaid claims plus the PV of expected cash outflows are greater than the PV 
of expected cash inflows. For such policies, a “Loss and loss expense reserves” liability is recorded for the sum of: (i) unpaid claims plus (ii) 
the excess of the PV of expected net cash outflows over the unearned premium revenue. Net cash inflow policies represent contracts where 
losses have been paid, but not yet recovered, such that the PV of expected cash inflows are greater than the sum of unpaid claims plus the PV 
of expected cash outflows. For such policies, a “Subrogation recoverable” asset is recorded for the difference between (i) the PV of expected 
net cash inflows and (ii) unpaid claims.  

The approaches used to estimate expected future losses and recoveries considers the likelihood of all possible outcomes. The evaluation process 
for determining expected losses is subject to certain judgments based on our assumptions regarding the probability of default by the issuer of 
the insured security, probability of settlement outcomes (which may include commutation settlements, refinancing and/or other settlement 
outcomes) and expected severity of credits for each insurance contract. Ambac’s loss reserves are based on management’s on-going review 
of the financial guarantee credit portfolio. Active surveillance of the insured portfolio enables Ambac’s Portfolio Risk Management ("PRM") 
group to track credit migration of insured obligations from period to period and update internal classifications and credit ratings for each 
transaction. Non-adversely classified credits are assigned a Class I or Survey List (“SL”) rating while adversely classified credits are assigned 
a rating of Class IA through Class V. The criteria for an exposure to be assigned an adversely classified credit rating includes the deterioration 
of an issuer’s financial condition, underperformance of the underlying collateral (for collateral dependent transactions such as mortgage-
backed or student loan securitizations), poor performance by the servicer of the underlying collateral and other adverse economic events or 
trends. The servicer of the underlying collateral of an insured securitization transaction is a consideration in assessing credit quality because

(Dollar Amounts in Thousands, Except Share Amounts)

the servicer’s performance can directly impact the performance of the related issue. For example, a servicer of a mortgage-backed securitization 
that does not remain current in its collection loss mitigation efforts could cause an increase in the delinquency and potential default of the 
underlying obligation. Similarly, loss severities increase when a servicer does not effectively handle loss mitigation activities such as (i) the 
advancing of delinquent principal and interest and of default related expenses which are deemed to be recoverable by the servicer, (ii) pursuit 
of loan charge-offs which maximize cash flows from the mortgage loan pool, and (iii) foreclosure and real estate owned disposition strategies 
and timelines. All credits are assigned risk classifications by PRM group using the following guidelines: 

CLASS I - “Fully Performing - Meets Ambac Criteria with Remote Probability of Claim” - Credits that demonstrate adequate security and 
structural protection with a strong capacity to pay interest, repay principal and perform as underwritten. Factors supporting debt  service 
payment and performance are considered unlikely to change and any such change would not have a negative impact upon the fundamental 
credit quality. 

SURVEY LIST - “Investigation of Specific Condition or Weakness Underway” - Credits that require additional analysis to determine if adverse 
classification is warranted. These credits may lack information or demonstrate a weakness but further deterioration is not expected. 

CLASS IA - “Potential Problem with Risks to be Dimensioned” - Credits that are fully current and monetary default or claims-payment are 
not anticipated. The payor’s or issuer’s financial condition may be deteriorating or the credits may lack adequate collateral. A structured 
financing may also evidence weakness in its fundamental credit quality as evidenced by its under-performance relative to its modeled projections 
at underwriting, issues related to the servicer’s ability to perform or questions about the structural integrity of the transaction. While these 
credits may still retain an investment grade rating, they usually have experienced or are vulnerable to a ratings downgrade. Further investigation 
is required to dimension and correct any deficiencies. A complete legal review of documents may be required. An action plan should be 
developed with triggers for future classification changes upward or downward. 

CLASS II - “Substandard Requiring Intervention” - Credits whose fundamental credit quality has deteriorated to the point that timely payment 
of debt service may be jeopardized by adversely developing trends of a financial, economic, structural, managerial or political nature. No 
claim payment is currently foreseen but the probability of loss or claim payment over the life of the transaction is now existent (generally 10% 
or greater probability). Class II credits may be border-line or below investment grade (BBB- to B). Prompt and sustained action must be taken 
to execute a comprehensive loss mitigation plan and correct deficiencies. 

CLASS III - “Doubtful with Clear Potential for Loss” - Credits whose fundamental credit quality has deteriorated to the point that timely 
payment of debt service has been or will be jeopardized by adverse trends of a financial, economic, structural, managerial or political nature 
which, in the absence of positive change or corrective action, are likely to result in a loss. The probability of monetary default or claims paying 
over the life of the transaction is generally 50% or greater. Full exercise of all available remedial actions is required to avert or minimize 
losses. Class III credits will generally be rated below investment grade (B to CCC). 

CLASS IV - “Imminent Default or Defaulted” - Monetary default or claim payments have occurred or are expected imminently. Class IV 
credits are generally rated D. 

CLASS V - “Fully Reserved” - The credit has defaulted and payments have occurred. The claim payments are scheduled and known, reserves 
have been established to fully cover such claims, and no claim volatility is expected. 

The population of credits evaluated in Ambac’s loss reserve process are: (i) all adversely classified credits (Class IA through V) and ii) non-
adversely classified credits (Class I and SL) which had an internal Ambac rating downgrade since the transaction’s inception. One of two 
approaches is then utilized to estimate losses to ultimately determine if a loss reserve should be established. The first approach is a statistical 
expected loss approach, which considers the likelihood of all possible outcomes. The “base case” statistical expected loss is the product of: 
(i) the par outstanding on the credit; (ii) internally developed historical default information (taking into consideration internal ratings and 
average life of an obligation); (iii) internally developed loss severities; and (iv) a discount factor. The loss severities and default information 
are based on rating agency information, are specific to each bond type and are established and approved by senior PRM officers.  For certain 
credit exposures, Ambac’s additional monitoring, loss remediation efforts and probabilities of potential settlement outcomes may provide 
information relevant to adjust this estimate of “base case” statistical expected losses.  Analysts may accept the “base case” statistical expected 
loss as the best estimate of expected loss or assign multiple probability weighted scenarios to determine an adjusted statistical expected loss 
that better reflects management’s view of a given transaction’s expected losses, as well as the potential for additional remediation activities 
(i.e. commutations). 

The second approach entails the use of cash-flow based models to estimate expected losses (future claims, net of potential recoveries, expected 
to be paid to the holder of the insured financial obligation). Ambac’s PRM group will consider the likelihood of all possible outcomes and 
develop appropriate cash flow scenarios. This approach can include the utilization of internal or third party models to project future losses 
and resultant claim payment estimates. We utilize cash flow models for residential mortgage-backed (RMBS), student loan, and other exposures. 
RMBS and student loan models use historical performance of the collateral pools in order to then derive future performance characteristics, 
such as default and voluntary prepayment rates, which in turn determine projected future claim payments.  In other cases, such as many public 
finance exposures including our Puerto Rico exposures, we do not specifically forecast resources available to pay debt service in the cash flow

model itself.  Rather, we consider the issuers’ overall ability and willingness to pay, including the fiscal, economic, legal and political framework. 
In this approach a probability-weighted expected loss estimate is developed based on assigning probabilities to multiple claim payment scenarios 
and applying an appropriate discount factor. Additionally, we assign a probability to the issuer’s ability to refinance an insured issue and/or 
Ambac’s ability to execute a potential settlement (i.e. commutation) of the insurance policy, including the impact on future installment premiums. 
The  commutation  scenarios  and  the  related  probabilities  of  occurrence  vary  by  transaction,  depending  on  our  view  of  the  likelihood  of 
negotiating such a transaction with issuers and/or investors. 

The estimated expected recovery component of expected losses include: (i) recoveries related to contractual breaches of RMBS representations 
and warranties by transaction sponsors, which is discussed further in the “RMBS Representation and Warranty Subrogation Recoveries” 
section  below,  (ii)  excess  spread  within  an  RMBS  transaction's  cash  flow  structure,  and  (iii)  other  recoveries,  including  other  litigation 
recoveries. Ambac does not include expected recoveries from litigation attributed solely to fraudulent inducement claims in our estimate of 
representation and warranty subrogation recoveries, since any remedies under such claims would be non-contractual.

The discount factor applied to the statistical expected loss approach is based on a risk-free discount rate corresponding to the remaining 
expected weighted-average life of the exposure and the exposure currency. For the cash flow scenario approach, discount factors are applied 
based on a risk-free discount rate term structure and correspond to the date of each respective cash flow payment or recovery and the exposure 
currency. Discount factors are updated for the current risk-free rate each reporting period. 

Ambac establishes loss expense reserves based on our estimate of expected net cash outflows for loss expenses, such as legal and consulting 
costs. 

RMBS Representation and Warranty Subrogation Recoveries: 

Ambac records as a component of its loss reserve estimate, subrogation recoveries related to securitized loans in RMBS transactions that 
breached certain representations and warranties described herein. Generally, the sponsor of an RMBS transaction provided representations 
and warranties with respect to the securitized loans, including representations with respect to the loan characteristics, the absence of borrower 
fraud in the underlying loan pools, or other misconduct in the origination process and attesting to the compliance of loans with the prevailing 
underwriting policies. In such cases, the sponsor of the transaction is contractually obligated to repurchase, cure or substitute collateral for 
any loan that breaches the representations and warranties. Ambac or its counsel have engaged consultants with significant mortgage underwriting 
experience to review the underwriting documentation for mortgage loans underlying certain insured RMBS transactions which exhibited 
exceptionally poor performance. Factors which Ambac believes to be indicative of poor performance include (i) increased levels of early 
payment defaults, (ii) significant numbers of loan liquidations or charge-offs and resulting high levels of losses, and (iii) rapid elimination of 
credit protections inherent in the transactions’ structures. With respect to item (ii), “loan liquidations” refers to loans for which the servicer 
has liquidated the related collateral and the securitization has realized losses on the loan; “charge-offs” refers to loans which have been written 
off as uncollectible by the servicer, generating no recoveries to the securitization, and may also refer to the unrecovered balance of liquidated 
loans. In either case, the servicer has taken actions to recover against the collateral, and the securitization has incurred losses to the extent 
such actions did not result in full repayment of the borrower’s obligations. 

Generally, subsequent to the forensic exercise of examining loan files to ascertain whether the loans conformed to the representations and 
warranties, we submit nonconforming loans for repurchase to the contractual counterparty bearing the repurchase obligation, which is typically 
the transaction sponsor. To effect a repurchase, depending on the transaction, the sponsor is obligated to repurchase the loan at (a) for loans 
which have not been liquidated or charged off, either (i) the current unpaid principal balance of the loan, (ii) the current unpaid principal 
balance plus accrued unpaid interest, or (iii) the current unpaid principal balance plus accrued interest plus unreimbursed servicer advances/
expenses and/or trustee expenses resulting from the breach of representations and warranties that trigger the repurchase, and (b) for a loan 
that has already been liquidated or charged-off, the amount of the realized loss (which in certain cases may exclude accrued unpaid interest). 
In  cases  where  loans  are  repurchased  by  a  sponsor,  the  effect  is  typically  to  offset  current  period  losses  and  then  to  increase  the  over-
collateralization of the securitization, depending on the extent of loan repurchases and the structure of the securitization. Specifically, the 
repurchase price is paid by the sponsor to the securitization trust which holds the loan. The cash becomes an asset of the trust, replacing the 
loan that was repurchased by the sponsor. On a monthly basis the cash received related to loan repurchases by the sponsor is aggregated with 
cash collections from the underlying mortgages and applied in accordance with the trust indenture payment waterfall. This payment waterfall 
typically includes principal and interest payments to the note holders, various expenses of the trust and reimbursements to Ambac, as financial 
guarantor, for previously paid claims. Notwithstanding the reimbursement of previous claim payments, to the extent there continues to be 
insufficient cash in the waterfall in the current month to make scheduled principal and interest payments to the note holders, Ambac is required 
to make additional claim payments to cover this shortfall. Ambac may also receive payments directly from transaction sponsors in settlement 
of their repurchase obligations pursuant to negotiated settlement agreements or otherwise as a result of related litigation. 

Ambac’s approach in estimating subrogation recoveries is a function of the population of loan files the sponsor makes available for review. 
In transactions where Ambac has been provided access to loans files for all loans in the original loan pool, we utilize a “random sample” 
approach to estimate subrogation recoveries. Prior to the June 30, 2014 reporting period, in transactions where Ambac had only obtained loan 
files for seriously delinquent or defaulted loans, we utilized an “adverse sample” approach to estimate subrogation recoveries. Beginning with 
the June 30, 2014 reporting period, as a result of gaining further access to loan files, the random sample approach has been utilized for all 
transactions which were previously evaluated using the adverse sample approach. Both approaches are described in further detail below. We

(Dollar Amounts in Thousands, Except Share Amounts)

do not include estimates of damages attributed solely to fraudulent inducement claims in our estimate of subrogation recoveries under either 
approach. 

While the obligation by sponsors to repurchase loans with material breaches is clear, generally the sponsors have not yet honored those 
obligations without actual or threatened litigation. Ambac has utilized the results of the above described loan file examinations to make demands 
for loan repurchases from sponsors or their successors and, in certain instances, as a part of the basis for litigation. Ambac’s approach to 
resolving these disputes has included negotiating with individual sponsors at the transaction level and in some cases at the individual loan 
level and has resulted in the repurchase of some loans. Ambac has initiated and will continue to pursue lawsuits seeking compliance with the 
repurchase obligations in the securitization documents. 

Ambac has performed the above-mentioned, detailed examinations on a variety of second-lien and first-lien transactions that have experienced 
exceptionally poor performance. However, the loan file examinations and related estimated recoveries we have reviewed and recorded to date 
have been limited to only those transactions whose sponsors (or their successors) are subsidiaries of large financial institutions, all of which 
carry an investment grade rating from at least one nationally recognized rating agency, or are otherwise deemed to have the financial wherewithal 
to live up to their repurchase obligations. While our contractual recourse is generally to the sponsor/subsidiary, rather than to the parent, each 
of these large institutions has significant financial resources and may have an ongoing interest in mortgage finance, and we therefore believe 
that the financial institution/parent would ultimately assume financial responsibility for these obligations if the sponsor/subsidiary is unable 
to honor its contractual obligations or pay a judgment that we may obtain in litigation. Additionally, in the case of successor institutions, we 
are not aware of any provisions that explicitly preclude or limit the successors’ ability to honor the obligations of the original sponsor. Certain 
successor  financial  institutions  have  made  significant  payments  to  certain  claimants  to  settle  breaches  of  representations  and  warranties 
perpetrated by sponsors that have been acquired by such financial institutions.  In addition, Ambac received a significant payment in 2016 
from JP Morgan to settle RMBS-related litigation. As a result of these factors, we did not make significant adjustments to our estimated 
subrogation recoveries with respect to the credit risk of these sponsors or their successors. 

Our ability to recover the RMBS subrogation recoveries is subject to significant uncertainty, including risks inherent in litigation, collectability 
of such amounts from counterparties and/or their respective parents and affiliates, timing of receipt of any such recoveries, intervention by 
OCI which could impede our ability to take actions required to realize such recoveries and uncertainties inherent in the assumptions used in 
estimating such recoveries. 

Random sample approach: 

The random sample approach to estimate subrogation recoveries is based on obtaining a random sample of the original loans in the pool, using 
a protocol developed by a statistical expert. In this approach, the ratio of: (a) loans identified in the sample as having materially breached 
representations and warranties to (b) the total loan sample size, is applied (extrapolated) to the sum of realized and estimated future collateral 
pool losses to determine an estimated repurchase obligation. We limit the estimated repurchase obligation by ever-to-date incurred losses, with 
respect to the remaining steps in this approach. 

Multiple probability-weighted scenarios are developed by applying various realization factors to the estimated repurchase obligation. The 
realization factors in these scenarios were developed using Ambac’s own assumptions about the likelihood of outcomes based on all the 
information available to it including, but not limited to, (i) discussions with external legal counsel and their views on ultimate settlement and/
or litigation outcomes, (ii) experience with loan put back negotiations where the existence of a material breach was debated and negotiated at 
the loan level, (iii) the pervasiveness of the breach rates and (iv) experience in settling similar claims. The probability weightings are developed 
based on the unique facts and circumstances for each transaction. The sum of these probability-weighted scenarios represents the undiscounted 
subrogation recovery, which is then discounted using a factor derived from a risk-free discount rate term structure that corresponds to the date 
of each respective recovery.  Discount factors are updated for the current risk-free rate each reporting period. 

Adverse sample approach: 

The adverse sample approach was used in transactions where Ambac was only given access by the sponsor to impaired loan files, meaning 
loans greater than 90 days past due, charged off, or in foreclosure, REO or bankruptcy. This limitation precluded us from selecting a valid 
random sample from the entire loan pool. Consequently, the adverse sample approach utilized the following subsets of loans to estimate a 
repurchase obligation: (i) loans identified as breaching representations and warranties (i.e. adverse loans) taken from a sample of impaired 
loans  and  (ii)  transactions  identified  where  the  underlying  loans  have  similar  attributes,  including  but  not  limited  to  type,  vintage  and 
composition, to loans that were included in RMBS settlements between the same sponsor and other parties, and where the transactions had 
substantially similar representations and warranties (i.e. “prototype transactions”). The calculation of subrogation recovery with respect to the 
adverse loan subset was based on the original principal balance of the loans in the adverse sample. 

Multiple probability-weighted scenarios were then developed by applying various realization factors to the estimated repurchase obligations 
under both subsets of loans. The realization factors in these scenarios were developed using assumptions similar to those discussed in the 
random sample approach above, as well as an internal analysis of previous RMBS settlements. The sum of these probability-weighted scenarios 
represents the undiscounted subrogation recovery, which is then discounted using a factor derived from a risk-free discount rate term structure 
that corresponds to the date of each respective recovery.  Discount factors are updated for the current risk-free rate each reporting period.

Obligations under Investment Agreements: 

Ambac's investment agreements were written principally to asset-backed and structured finance issuers, states, municipalities and municipal 
authorities, and require Ambac to pay an agreed-upon rate of interest based on funds deposited. Proceeds from these investment agreement 
obligations were used to invest in fixed income investments. Interest income from these investments is included in Net investment income on 
the Consolidated Statements of Total Comprehensive Income. 

Obligations under investment agreements are reported as liabilities on the Consolidated Balance Sheets at their principal value less unamortized 
discount. The carrying value of these obligations is adjusted for principal paid and interest credited to the account. Interest expense is computed 
based upon daily outstanding liability balances at rates and periods specified in the agreements adjusted for accretion of discount, and is 
included in Interest expense on the Consolidated Statements of Total Comprehensive Income. 

Long-Term Debt:

Long-term debt issued by Ambac is carried at par value less unamortized discount. Accrued interest and discount accretion on long-term debt 
is reported as Interest expense on the Consolidated Statements of Total Comprehensive Income.   To the extent Ambac repurchases its long-
term debt or the Rehabilitator redeems Segregated Account surplus notes, which may also trigger a proportionate redemption in General 
Account surplus notes, such repurchases or redemptions may be settled for an amount different than the carrying value of the obligation. Any 
difference between the settlement payment and carrying value of the obligation is reported in Net realized gains (losses) on extinguishment 
of debt on the Consolidated Statements of Total Comprehensive Income.  

Long-term debt issued by VIEs consolidated as a result of Ambac's variable interest arising from financial guarantees written by Ambac's 
subsidiaries, is carried at fair value with changes in fair value recorded as Income (loss) on variable interest entities on the Consolidated 
Statements of Total Comprehensive Income. 

Employee Benefits:

Postretirement and Postemployment Benefits: 

Ambac provides postretirement and postemployment benefits, including health and life benefits covering employees who meet certain age 
and service requirements. Ambac accounts for these benefits under the accrual method of accounting. Amounts related to the postretirement 
health benefits liability are established and charged to expense based on actuarial determinations.  

Long Term Incentive and Stock Compensation Plans: 

Incentive compensation is a key component of our compensation strategy. Incentive compensation payouts are based on the execution of our 
strategies at the Company, as well as business unit and individual performance. In January of each year a determination is made as to the total 
amount of incentive compensation to be awarded, including amounts in the form of stock grants. The Ambac 2013 Incentive Compensation 
Plan (the “Equity Plan”) provides for the granting of stock options, restricted stock, stock appreciation rights, restricted and performance units 
and other awards that are valued or determined by reference to Ambac's common stock to employees and directors.  In March 2014, Ambac 
developed a long term incentive compensation plan (“LTIP”) as a sub-plan of the 2013 Plan. This LTIP allows for both cash and equity 
performance awards to US employees.  In 2015, Ambac UK 's Board of Directors adopted a long term incentive plan which provides cash 
based performance awards to Ambac UK employees.

Ambac recognizes compensation costs for all equity classified awards granted at fair value with an estimation of forfeitures for all unvested 
shares. 

• 

• 

Stock options and restricted stock units granted only require future service and accordingly the respective fair value is amortized over 
the relevant service period.  

Performance stock units granted and performance cash awards require both future service and achieving specified performance targets 
to vest and accordingly compensation costs are only recognized when the achievement of the performance conditions are considered 
probable. Once deemed probable, such compensation costs are amortized over the relevant service period.  Compensation costs are 
initially based on the probable outcome of the performance conditions and adjusted for subsequent changes in the estimated or actual 
outcome each reporting period as necessary.  Changes in the estimated or actual outcome of a performance condition are recognized 
by reflecting a retrospective adjustment to compensation cost in the current period.

Depreciation and Amortization: 

Depreciation of furniture and fixtures and electronic data processing equipment is charged over the estimated useful lives of the respective 
assets, ranging from three to five years, using the straight-line method. Amortization of leasehold improvements is charged over the remaining 
term of the respective operating lease using the straight-line method.

investment gains, in the amount of $30,179, $5,816 and $5,235 for the years ended December 31, 2016, 2015 and 2014, respectively; 

Remeasurement of premium receivables, classified in Other income, in the amount of $8,003, $(2,555) and $(4,470) for the years 
ended December 31, 2016, 2015 and 2014, respectively; and

Remeasurement of credit derivative liabilities, classified in Net change in fair value of credit derivative, in the amount of $32, $3,981
and $3,234 for the years ended December 31, 2016, 2015 and 2014, respectively.

Reorganization items: 

Entities operating in bankruptcy and expecting to reorganize under Chapter 11 of the Bankruptcy Code are subject to the additional accounting 
and financial reporting guidance under the Reorganization Topic of the Accounting Standards Codification. For the purpose of presenting an 
entity’s financial condition, the financial statements for periods including and after filing the Chapter 11 petition shall distinguish transactions 
and events that are directly associated with the reorganization from the ongoing operations of the business.  Professional advisory fees and 
other  costs  directly  associated  with  our  reorganization  are  reported  separately  as  reorganization  items.  The  reorganization  items  in  the 
Consolidated Statements of Total Comprehensive Income consisted of professional fees of $204 and U.S. Trustee fees of $7 for the year ended 
December 31, 2014.

Income Taxes: 

Ambac files a consolidated U.S. Federal income tax return with its subsidiaries. Ambac UK files tax returns in both the United Kingdom and 
Italy (for its Milan branch). Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between 
the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are 
measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be 
recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the 
enactment date. 

Ambac evaluates our deferred income taxes quarterly to determine if valuation allowances are required. The Income Taxes Topic of the ASC 
requires that companies assess whether valuation allowances should be established against their deferred tax assets based on the consideration 
of all available evidence using a ‘more likely than not” standard. In making such judgments, significant weight is given to evidence that can 
be objectively verified. 

The level of deferred tax asset recognition is influenced by management’s assessment of future profitability, which depends on the existence 
of sufficient taxable income of the appropriate character (ordinary vs. capital) within the carry forward periods available under the tax law. 
We  previously determined that we would not be able to realize all of our deferred tax assets in the future, and therefore we reduced such 
amounts through a charge to the Statement of Total Comprehensive Income in the period in which that determination was made. Refer to  Note 
15. Income Taxes for further discussion of the Company's tax positions.

The Income Taxes Topic of the ASC provides a framework to determine the appropriate level of tax reserves for uncertain tax positions. This 
framework prescribes a more-likely-than-not threshold for financial statement recognition and measurement of a tax position taken or expected 
to be taken in a tax return. Ambac also accrues interest and penalties related to these unrecognized tax benefits in the provision for income 
taxes.

Net Income Per Share: 

Basic net income per share is computed by dividing net income attributable to common stockholders by the weighted-average number of 
common shares outstanding, inclusive of unsettled vested restricted stock units. Diluted net income per share is computed by dividing net 
income attributable to common stockholders by the weighted-average number of common shares outstanding plus all dilutive potential common 
shares outstanding during the period. All dilutive potential common shares outstanding consider common stock deliverable pursuant to warrants 
issued under the Reorganization Plan and those pursuant to stock options and non-vested restricted and performance stock units. 

Reclassifications:

Certain reclassifications have been made to prior years' amounts to conform to the current year's presentation.

Recently Adopted Accounting Standards:

The following accounting standards were adopted by Ambac effective December 31, 2016:

Disclosure of Recently Issued Accounting Standards

Accounting Standard Update ("ASU") 2017-03, Accounting Changes and Error Corrections (Topic 250) and Investments - Equity Method 
and Joint Ventures (Topic 323) - Amendments to SEC Paragraphs Pursuant to Staff Announcements at the September 22, 2016 and November 
17, 2016 EITF Meetings was issued by the Financial Accounting Standards Board ("FASB") in January 2017 and is effective for the December 
31, 2016 reporting period.  The primary topic in the ASU relevant to Ambac is the FASB codification of a SEC Staff Announcement that 
addresses disclosures the SEC expects to see for the following three accounting standards prior to their adoption:  ASU 2014-09, Revenue 
from Contracts with Customers; ASU 2016-02, Leases; and ASU 2016-13, Measurement of Credit Losses on Financial Instruments. In addition 
to the disclosures already required by the SEC for new accounting standards not yet implemented, with respect to the aforementioned standards 
the SEC expects companies to describe the status of its process to implement the new standards and the significant implementation matters 
yet to be addressed.  We have made the required disclosures for these new standards in the Future Application of Accounting Standards section 
below. 

Going Concern Assessment

ASU 2014-15, Presentation of Financial Statements - Going Concern (Subtopic 205-40), Disclosure of Uncertainties about an Entity's Ability 
to Continue as a Going Concern requires management to assess, at each interim period and annual reporting period, whether substantial doubt 
exists about the company's ability to continue as a going concern within one year after the date that the financial statements are issued or 
available to be issued. If management determines there is substantial doubt, it should also consider whether the substantial doubt is overcome 
by management's plans, and provide certain disclosures based on facts and circumstances.  Refer to Note 1. Background and Business Description 
for management's disclosures regarding Ambac's ability to continue as a going concern.

The remaining accounting standards discussed in this section were adopted by Ambac effective January 1, 2016: 

Disclosures about Short-Duration Contracts

ASC 2015-09, Financial Services - Insurance (Topic 944) - Disclosures about Short-Duration Contracts. The primary objective of this ASU 
is to improve disclosures for insurance entities which issue short-duration contracts. The ASU made significant amendments to the Short-
Duration Contract disclosure section and limited amendments affecting the General disclosure section of Topic 944.  Ambac, as a provider of 
financial  guarantee  contracts,  is  subject  to  the  General  sections  but  not  the  Short-Duration  Contract  sections  of  Topic  944.  The  limited 
amendments made to the General disclosure section did not effect Ambac's financial statement disclosures. 

Eliminating Certain Fair Value Disclosures

ASU 2015-07, Fair Value Measurement (Topic 820) - Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share 
(or Its Equivalent).  Reporting entities are permitted to use net asset value ("NAV") as a practical expedient to measure the fair value of certain 
investments. Under previous GAAP, investments that use the NAV practical expedient to measure fair value were categorized within the fair 
value hierarchy as level 2 or level 3 investments depending on their redemption attributes, which has led to diversity in practice. This ASU 
will remove the requirement to categorize within the fair value hierarchy all investments that use the NAV practical expedient for fair value 
measurement purposes.  Furthermore, the ASU will remove the requirement to make certain disclosures for all investments that are eligible 
to be measured at fair value using the NAV practical expedient. Upon adoption Ambac applied this ASU retrospectively to all prior periods 
presented, which was not material to Ambac's financial statements. Disclosures that were impacted by adoption of this ASU are shown in Note 
9. Fair Value Measurements. 

Debt Issuance Costs

ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30).  This ASU simplifies the presentation of debt issuance costs by requiring 
that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount 
of that debt liability, consistent with debt discounts, rather than as a deferred asset. The recognition and measurement guidance for debt issuance 
costs are not affected by the amendments in this ASU.  The ASU requires retrospective application to all prior periods presented.  Adoption 
of this ASU did not have a material effect on Ambac’s financial statements.

Consolidation of Variable Interest Entities - Various Changes

ASU 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis.  This ASU makes changes to the variable interest 
("VIE") model and voting interest ("VOE") model consolidation guidance. The main provisions of the ASU include the following: i) adding 
a requirement that limited partnerships and similar legal entities must provide partners with either substantive kick-out rights or substantive 
participating rights over the general partner to qualify as a VOE rather than a VIE; ii) eliminating the presumption that the general partner 
should consolidate a limited partnership; iii) eliminating certain conditions that need to be met when evaluating whether fees paid to a decision 
maker or service provider are considered a variable interest; iv) excluding certain fees paid to decision makers or service providers when 
evaluating which party is the primary beneficiary of a VIE; and v) revising how related parties are evaluated under the VIE guidance.  Lastly, 
the ASU eliminates the indefinite deferral of FAS 167, which allowed reporting entities with interests in certain investment funds to follow 
previous guidance in FIN 46 (R).  However, the ASU permanently exempts reporting entities from consolidating registered money market 
funds that operate in accordance with Rule 2a-7 of the Investment Company Act of 1940. Adoption of this ASU did not affect Ambac’s financial 
statements.

Eliminating Concept of Extraordinary Items

ASU  2015-01,  Income  Statement  -  Extraordinary  and  Unusual  Items  (Subtopic  225-20):  Simplifying  Income  Statement  Presentation  by 
Eliminating the Concept of Extraordinary Items.  Extraordinary items are defined as both unusual in nature and infrequent in occurrence. 
Under previous guidance, a reporting entity was required to separately present and disclose extraordinary items. This ASU eliminates from 
current U.S. GAAP the concept of extraordinary items.  However, the ASU retains the presentation and disclosure guidance for items that are 
unusual in nature or occur infrequently. Items that meet either or both of these criteria must be presented as a separate component on the face 
of the income statement or, alternatively, disclosed in the notes to the financial statements. Adoption of this ASU did not affect Ambac’s 
financial statements.

Hybrid Financial Instruments

ASU 2014-16, Derivatives and Hedging (Topic 815): Determining Whether the Host Contract in a Hybrid Financial Instrument Issued in the 
Form of a Share Is More Akin to Debt or to Equity.  The objective of this ASU is to eliminate the existing diversity in practice in accounting 
for hybrid financial instruments issued in the form of a share.  A hybrid financial instrument consists of a “host contract” into which one or 
more derivative terms have been embedded.   The ASU requires an entity to consider the terms and features of the entire financial instrument, 
including the embedded derivative features, in order to determine whether the nature of the host contract is more akin to debt or to equity. 
Adoption of this ASU did not affect Ambac’s financial statements. 

Consolidation of Collateralized Financing Entities

ASU 2014-13, Consolidation (Topic 810): Measuring the Financial Assets and the Financial Liabilities of a Consolidated Collateralized 
Financing Entity.  A collateralized financing entity ("CFE") is a variable interest entity with nominal or no equity that holds financial assets 
and issues beneficial interests in those financial assets. The beneficial interests, which are financial liabilities of the CFE, have contractual 
recourse only to the related assets of the CFE.  Currently, a reporting entity that is required to consolidate a CFE may elect to measure the 
financial assets and financial liabilities of the CFE at fair value.  Under the ASU, a reporting entity may elect to measure such assets and 
liabilities using either: i) the measurement principles in the Fair Value Measurement Topic of the ASC or ii) an alternative measurement 
approach specified in the ASU. The alternative measurement approach uses the more observable of either the fair value of the financial assets 
or financial liabilities to measure both.  However, a reporting entity may not use the alternative measurement approach if it guarantees all or 
a portion of the CFE's beneficial interests.  Furthermore, entities that do not (or may not) use the alternative measurement approach may not 
attribute any of the CFE's earnings to noncontrolling interests. The ASU is intended to address diversity in practice in accounting for the 
measurement difference between financial assets and financial liabilities of CFEs.  Most of the CFEs consolidated by Ambac are the result of 
Ambac’s guarantee of the CFEs' respective beneficial interests. As a result, we may not apply the measurement alternative in this ASU to those 
CFEs.  Previously, Ambac had one consolidated CFE where we elected to measure the financial assets and financial liabilities at fair value 
and where a portion of the CFEs earnings were attributed to noncontrolling interests. As a result, we have elected to use a modified retrospective 
approach in adopting this ASU and have reclassified $6,442 related to this CFE from noncontrolling interest to retained earnings on the balance 
sheet effective January 1, 2016.  There was no impact on the Statement of Comprehensive Income.

Share -Based Payments

ASU 2014-12, Compensation - Stock Compensation (Topics 718) - Accounting for Share-Based Payments When the Terms of an Award Provide 
That a Performance Target Could Be Achieved after the Requisite Service Period.  Generally, share-based payment awards that require a 
specific performance target to be met also require an employee to render service until the performance target is achieved.  However, in some 
cases, the terms of an award may provide that the performance target could be achieved after the employee completes the requisite service 
period. Under previous U.S. GAAP, there was no explicit guidance on how to account for share-based payment awards with performance 
targets that could be achieved after the requisite service period.  This ASU is intended to resolve diversity in practice with respect to how the 
performance target is considered in the grant-date fair value of the award, which impacts the amount of compensation cost recognized over 
time. The ASU requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated 
as a performance condition.  As a result, the performance target would not be reflected in estimating the fair value of the award at the grant

date.  As Ambac previously followed the guidance in ASU 2014-12 for its share-based awards which have performance targets, the adoption 
of this ASU had no impact on Ambac's financial statements.

Future Application of Accounting Standards:

Restricted Cash

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230) - Restricted Cash. Current GAAP does not include 
specific guidance on the cash flow classification and presentation of changes in restricted cash and restricted cash flow equivalents other than 
limited guidance for non-for-profit entities. This ASU is intended to resolve diversity in practice in the classification of changes in restricted 
cash and restricted cash flow equivalents on the statement of cash flows.  The new guidance requires that restricted cash and restricted cash 
equivalents be included with cash and cash equivalents when reconciling the beginning and ending period amounts on the statement of cash 
flows, along with certain disclosures.  ASU 2016-18 is effective for fiscal years beginning after December 15, 2017 and interim periods within 
those  fiscal  years.  Early  adoption  is  permitted,  including  adoption  in  an  interim  period.   Amendments  in  the ASU  should  be  applied 
retrospectively to all periods presented. Ambac will adopt this ASU on January 1, 2018. We are currently evaluating the impact on Ambac's 
financial statements.

Consolidation of Variable Interest Entities - Decision Makers

In October 2016, the FASB issued ASU 2016-17, Consolidation (Topic 810) - Interests Held through Related Parties That Are under Common 
Control.  The new guidance changes how a reporting entity that is a single decision maker for a VIE will consider its indirect interests in that 
VIE when determining whether the reporting entity is the primary beneficiary and should consolidate the VIE.  Under current GAAP, a single 
decision maker in a VIE is required to consider an indirect interest held by a related party under common control in its entirety. Under the new 
ASU, the single decision maker will consider the indirect interest on a proportionate basis. ASU 2016-17 is effective for fiscal years beginning 
after December 15, 2016 and interim periods within those fiscal periods.  Early adoption is permitted, including adoption in an interim period. 
Ambac will adopt this ASU on January 1, 2017. Adoption of this ASU is not expected to have a consequential impact on Ambac's financial 
statements.

Income Taxes

In October 2016,  the FASB issued ASU 2016-16, Income Taxes (Topic 740) - Intra-Entity Transfers of Assets Other Than Inventory.  Current 
GAAP prohibits the recognition of current and deferred income taxes for intercompany transfers of assets until the asset has been sold to an 
outside party. The ASU will require companies to recognize the income tax effects of intercompany sales and transfers of assets other than 
inventory, as income tax expense (or benefit) in the period in which the transfer occurs. ASU 2016-16 is effective for fiscal years beginning 
after December 15, 2017 and interim periods within those fiscal years. Early adoption is permitted as of the beginning of an annual reporting 
period for which financial statements (interim or annual) have not been issued.  Ambac has not determined whether it will early adopt this 
ASU and we are currently evaluating its impact on Ambac's financial statements.

Classification of Certain Cash Receipts and Cash Payments

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230) - Classification of Certain Cash Receipts and Cash 
Payments. The ASU resolves diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement 
of cash flows. Transactions addressed in the ASU that may impact Ambac are as follows:

•  Debt prepayment or debt extinguishment costs - Such payments will be classified as a financing cash outflow.

• 

Settlement of zero-coupon debt or other debt with coupon rates that are insignificant in relation to the effective interest rate of the 
borrowing - The portion of the cash payment attributable to accreted interest will be classified as an operating cash outflow and the 
portion attributable to the principal will be classified as a financing cash outflow.

•  Distributions from equity-method investees - An entity will elect one of the two following approaches. Under the "cumulative earnings 
approach": i) distributions received up to the amount of cumulative earnings recognized will be treated as returns on investments and 
classified as cash inflows from operating activities and ii) distributions received in excess of earnings recognized will be treated as 
returns  of  investments  and  classified  as  cash  inflows  from  investing  activities.    Under  the  "nature  of  the  distribution"  approach, 
distributions received will be classified based on the nature of the activity that generated the distribution (i.e. classified as a return on 
investment or return of investment), when such information is available to the investor.

• 

Beneficial interests in securitization transactions - Any beneficial interests obtained in financial assets transferred to an unconsolidated 
securitization  entity  will  be  disclosed  as  a  non-cash  investing  activity.    Subsequent  cash  receipts  from  the  beneficial  interests  in 
previously transferred trade receivables will be classified as cash inflows from investing activities.

ASU 2016-15 is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption is 
permitted, including adoptions within an interim period.  Ambac has not determined whether it will early adopt this ASU. Adoption of this 
ASU is not expected to have a consequential impact on Ambac's financial statements.

Measurement of Credit Losses on Financial Instruments

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326) - Measurement of Credit Losses on Financial 
Instruments.  This ASU significantly affects how reporting entities will measure credit losses for financial assets that are not accounted for at 
fair value through net income, which include loans, debt securities, trade receivables, net investments in leases, and certain off-balance sheet 
credit exposures.  For financial assets measured at amortized cost, the ASU replaces the "incurred loss" model, which generally delayed 
recognition of the full amount of credit losses until the loss was probable of occurring, with an "expected loss" model, which reflects an entity's 
current estimate of all expected credit losses. Expected credit losses for amortized cost assets will be recorded as a valuation allowance, with 
subsequent increases or decreases in the allowance reflected in the income statement each period.  For available-for-sale debt securities, credit 
losses under the ASU will be measured similarly to current GAAP. However, under the ASU, credit losses for available-for-sale securities will 
be recorded as a valuation allowance (similar to the amortized cost assets approach described above), rather than as a direct write-down of 
the security as is required under current GAAP. As a result, improvements to estimated credit losses for available-for-sale debt securities will 
be recognized immediately in the income statement rather than as interest income over time. The ASU is effective for annual periods beginning 
after December 15, 2019, including interim periods within those fiscal years.  Early adoption is permitted as of the fiscal year beginning after 
December 15, 2018. Ambac has not determined whether it will early adopt this ASU and we are currently evaluating its impact on Ambac's 
financial statements.   The significant implementation matters to be addressed include identifying the inventory of financial assets that will 
be affected by this standard, identifying new data requirements and data sources for implementing the expected loss model for those instruments 
not already using this model, and identifying and documenting accounting process changes, including related controls.

Improvements to Employee Share-Based Payment Accounting

In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation (Topic 718) - Improvements to Employee Share-Based 
Payment Accounting.  The objective of this ASU is to improve and simplify the accounting for employee share-based payment accounting. 
The amendments are as follows: (i) recognizing excess tax benefits and tax deficiencies as income tax expense, (ii) recognizing excess tax 
benefits regardless of whether it reduces taxes payable in the current period, (iii) classifying excess tax benefits related to share-based payments 
along with other income tax cash flows as an operating activity on the statement of cash flows, (iv) allowing companies to make an accounting 
policy election to either estimate forfeitures or account for forfeitures as they occur, for purposes of accruing compensation cost, (v) to qualify 
for equity classification treatment, permitting tax withholding by employees up to the maximum statutory tax rate and (vi) classifying cash 
paid by an employer to a taxing authority when directly withholding shares as a financing activity on the statement of cash flows. The ASU 
is effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods, with early adoption 
permitted.   Depending on the amendment, application will be prospective, retrospective or using a modified retrospective approach.  Ambac 
will adopt this ASU on January 1, 2017.  Adoption of this ASU will not have a material impact on Ambac's financial statements.

Equity Method of Accounting

In March 2016, the FASB issued ASU 2016-07, Investments-Equity Method and Joint Ventures (Topic 323) - Simplifying the Transition to the 
Equity Method of Accounting.  This ASU eliminates the requirement that when an investment qualifies for use of the equity method as a result 
of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and 
retained earnings retroactively as if the equity method had been in effect during all previous periods that the investment had been owned. The 
ASU will now require that at the date an available-for-sale equity security becomes qualified for the equity method of accounting, the reporting 
entity will recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income.  The ASU is effective 
for  fiscal  years,  and  interim  periods  within  those  fiscal  years,  beginning  after  December  15,  2016,  with  early  adoption  permitted.   The 
amendments should be applied prospectively upon  adoption.  Ambac will adopt this ASU on January 1, 2017. Adoption of this ASU is not 
expected to have a  consequential impact on Ambac's financial statements.

Contingent Put and Call Options in Debt Instruments

In March 2016, the FASB issued ASU 2016-06, Derivatives and Hedging (Topic 815) - Contingent Put and Call Options in Debt Instruments.  
Current accounting rules require that embedded derivatives be separated from the host contract in a financial instrument and accounted for 
separately  as  derivatives  if  certain  criteria  are  met.    One  of  these  criteria  is  that  the  economic  characteristics  and  risks  of  the  embedded 
derivatives are not "clearly and closely related" to the host contract. The objective of the ASU is to resolve diversity in practice in assessing 
embedded contingent put and call options. The ASU clarifies what steps are required when assessing whether the economic characteristics 
and risk of put and call options are clearly and closely related to their debt host contracts.  The ASU is effective for fiscal years beginning 
after December 15, 2016 and interim periods within those fiscal years, with early adoption permitted.  The ASU must be applied on a modified 
retrospective basis to existing debt instruments as of the beginning of the fiscal year for which the amendments are effective.  Ambac will 
adopt this ASU on January 1, 2017. Adoption of this ASU is not expected to have a consequential impact on Ambac's financial statements.

Leases

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The main difference between current U.S. GAAP and this ASU is the 
recognition of lease assets and lease liabilities for those leases classified as operating leases.  For operating leases, a lessee is required to: 1) 
recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in the balance sheet, 2) recognize 
a single lease cost, calculated so that the cost is allocated over the lease term generally on a straight-line basis and 3) classify all cash payment 
within operating activities in the statement of cash flows. The ASU is effective for fiscal years beginning after December 15, 2018, including

(Dollar Amounts in Thousands, Except Share Amounts)

interim periods within those fiscal years. The transition guidance requires lessees to recognize and measure leases at the beginning of the 
earliest period presented using a modified retrospective approach which include a number of optional practical expedients.  We will adopt 
ASU 2015-02 on January 1, 2019. We are evaluating the impact of this ASU, including the transitional practical expedients, on Ambac's 
financial statements. We believe Ambac's office leases will be the most significantly impacted by this ASU. The significant implementation 
matters to be addressed include identifying the remaining inventory of leases (i.e. equipment and other) that will be affected by this standard 
and identifying and documenting accounting process changes, including related controls.

Recognition and Measurement of Financial Assets and Liabilities

In  January  2016,  the  FASB  issued ASC  2016-01,  Financial  Instruments  -  Overall  (Subtopic  825-10)  -  Recognition  and  Measurement  of 
Financial Assets and Financial Liabilities.   The ASU makes the following targeted changes for financial assets and liabilities: i) requiring 
equity investments with readily determinable fair values to be measured at fair value with changes recognized in net income; ii) simplifying 
the impairment assessment of equity securities without readily determinable fair values using a qualitative approach; iii) eliminating disclosure 
of the method and significant assumptions used to fair value instruments measured at amortized cost on the balance sheet; iv) requiring use 
of the exit price notion when measuring the fair value of instruments for disclosure purposes; v) for financial liabilities where the fair value 
option has been elected, requiring the portion of the fair value change related to instrument-specific credit risk (which includes a Company's 
own credit risk) to be separately reported in other comprehensive income; vi) requiring the separate presentation of financial assets and liabilities 
by measurement category and form of financial asset (liability) on the balance sheet or accompanying notes; and vii) clarifying that the 
evaluation of a valuation allowance on a deferred tax asset related to available-for-sale securities should be performed in combination with 
the entity's other deferred tax assets. The ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within 
those years  Early adoption of item (v) above is permitted for financial statements (both annual and interim periods) that have not yet been 
issued.  We have not determined when we will adopt item (v) above of this ASU. We will adopt the remaining provisions of the ASU on 
January 1, 2018. We are evaluating the impact of this ASU on Ambac's financial statements. 

Revenue recognition

In May of 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) that amends the accounting guidance 
for recognizing revenue for contracts with customers to transfer goods and contracts for the transfer of non-financial assets unless those 
contracts are within the scope of other accounting standards.  ASU 2015-14 deferred the effective date of ASU 2014-09 to annual periods 
beginning after December 15, 2017, including interim periods within that reporting period. Ambac will adopt this ASU on January 1, 2018. 
While we are still evaluating the ASU, it does not apply to insurance contracts and most financial instruments and is therefore is not expected 
to have consequential impact on Ambac's financial statements. The significant implementation matters to be addressed include identifying 
contracts the Company may have that will be affected by this standard and identifying and documenting accounting process changes, including 
related controls.

3.        SPECIAL PURPOSE ENTITIES, INCLUDING VARIABLE INTEREST ENTITIES ("VIEs")

Ambac, with its subsidiaries, has engaged in transactions with special purpose entities, including VIEs, in various capacities. 

•  Ambac most commonly provides financial guarantees, including credit derivative contracts, for various debt obligations issued by 

special purpose entities, including VIEs ("FG VIEs"). 

•  Ambac sponsors special purpose entities that issued medium-term notes to fund the purchase of certain financial assets. 

•  Ambac monetized its ownership of the junior surplus note issued to it by the Segregated Account by depositing the junior surplus note 
into a newly formed VIE trust in exchange for cash and an owner trust certificate, which represents Ambac's right to residual cash 
flows from the junior surplus note.

•  Ambac is an investor in collateralized debt obligations, mortgage-backed and other asset-backed securities issued by VIEs and its 
ownership interest is generally insignificant to the VIE and/or Ambac does not have rights that direct the activities that are most 
significant to such VIE. 

FG VIEs:

Ambac’s subsidiaries provide financial guarantees in respect of assets held or debt obligations of special purpose entities, including VIEs. 
Ambac’s primary variable interest exists through this financial guarantee insurance or credit derivative contract. The transaction structures 
provide  certain  financial  protection  to Ambac.  This  financial  protection  can  take  several  forms;  however,  the  most  common  are  over-
collateralization, first loss and excess spread. In the case of over-collateralization (i.e., the principal amount of the securitized assets exceeds 
the principal amount of the debt obligations guaranteed), the structure allows the transaction to experience defaults among the securitized 
assets before a default is experienced on the debt obligations that have been guaranteed by Ambac’s subsidiaries. In the case of first loss, the 
financial guarantee insurance policy or credit derivative contract only covers a senior layer of losses on assets held or debt issued by special 
purpose entities, including VIEs. The first loss with respect to the assets is either retained by the asset seller or sold off in the form of equity 
or mezzanine debt to other investors. In the case of excess spread, the securitized assets contributed to special purpose entities, including VIEs,

generate interest cash flows that are in excess of the interest payments on the related debt; such excess cash flow is applied to redeem debt, 
thus creating over-collateralization. Generally, upon deterioration in the performance of a transaction or upon an event of default as specified 
in the transaction legal documents, Ambac will obtain certain loss remediation rights. These rights may enable Ambac to direct the activities 
of the entity that most significantly impact the entity’s economic performance. 

We determined that Ambac’s subsidiaries generally have the obligation to absorb a FG VIE's expected losses given that they have issued 
financial guarantees supporting the liabilities (and in certain cases assets). As further described below, we consolidated certain FG VIEs 
because: (i) we determined for certain transactions that experienced the aforementioned performance deterioration, that Ambac’s subsidiaries 
had the power, through voting rights or similar rights, to direct the activities that most significantly impact the VIE’s economic performance 
because certain triggers had been breached in these transactions resulting in Ambac's subsidiaries' ability to exercise certain loss remediation 
activities, or (ii) due to the passive nature of the VIEs’ activities, Ambac’s subsidiaries’ contingent loss remediation rights upon a breach of 
certain triggers in the future is considered to be the power to direct the activities that most significantly impact the VIEs’ economic performance. 
With respect to existing VIEs involving Ambac financial guarantees, Ambac is generally required to consolidate a VIE in the period that 
applicable triggers result in Ambac having control over the VIE’s most significant economic activities. A VIE is deconsolidated in the period 
that Ambac no longer has such control, which could occur in connection with insurance policies that are allocated to the Segregated Account, 
execution of remediation activities on the transaction or amortization of insured exposure, any of which may reduce the degree of Ambac’s 
control over a VIE.  Assets and liabilities of FG VIEs that are consolidated are reported  within Variable interest entity assets or Variable 
interest entity liabilities on the Consolidated Balance Sheets.  The net results from such FG VIEs are reported within Income (loss) on variable 
interest entities in the Consolidated Statements of Total Comprehensive Income.  

Upon initial consolidation of a FG VIE, we recognize a gain or loss in earnings for the difference between: (i) the fair value of the consideration 
paid, the fair value of any non-controlling interests and the reported amount of any previously held interests and (ii) the net amount, as measured 
on a fair value basis, of the assets and liabilities consolidated. Upon deconsolidation of a FG VIE, we recognize a gain or loss for the difference 
between: (i) the fair value of any consideration received, the fair value of any retained non-controlling investment in the VIE and the carrying 
amount  of  any  non-controlling  interest  in  the VIE  and  (ii) the  carrying  amount  of  the VIE’s  assets  and  liabilities.  Gains  or  losses  from 
consolidation and deconsolidation that are reported in earnings are reported within Income (loss) on variable interest entities on the Consolidated 
Statements of Total Comprehensive Income.

The impact of consolidating such FG VIEs on Ambac’s balance sheet is the elimination of transactions between the consolidated FG VIEs 
and Ambac’s operating subsidiaries and the inclusion of the FG VIE’s third party assets and liabilities. For a financial guarantee insurance 
policy issued to a consolidated VIE, Ambac does not reflect the financial guarantee insurance policy in accordance with the related insurance 
accounting rules under the Financial Services – Insurance Topic of the ASC. Consequently, upon consolidation, Ambac eliminates the insurance 
assets  and  liabilities  associated  with  the  policy  from  the  Consolidated  Balance  Sheets.  Such  insurance  assets  and  liabilities  may  include 
premium receivables, reinsurance recoverable, deferred ceded premium, subrogation recoverable, unearned premiums, loss and loss expense 
reserves, ceded premiums payable and insurance intangible assets. For investment securities owned by Ambac that are debt instruments issued 
by the VIE, the investment securities balance is eliminated upon consolidation. Ambac has not consolidated any VIEs during 2016, 2015 or 
2014 solely as a result of purchases of the VIE’s debt instruments.

As of December 31, 2016 consolidated FG VIE assets and liabilities relating to 12 consolidated entities were $13,367,834 and $13,235,425, 
respectively.  As of December 31, 2015, consolidated FG VIE assets and liabilities relating to 13 consolidated entities were $14,288,497 and 
$14,259,776, respectively. As of December 31, 2016, eight and four consolidated FG VIEs related to transaction insured by Ambac UK and 
Ambac Assurance and nine and four as of December 31, 2015.  As of December 31, 2016 FG VIE assets and liabilities of $12,950,009 and 
$12,833,466 and as of December 31, 2015, FG VIE assets and liabilities of $13,769,985 and 13,636,628 related to transactions guaranteed by 
Ambac UK.  The remaining balance of consolidated FG VIE assets and liabilities are related to transactions guaranteed by Ambac Assurance.   
Ambac is not primarily liable for, and generally does not guarantee all of the debt obligations issued by the VIEs. Ambac would only be 
required to make payments on the VIE debt obligations in the event that the issuer of such debt obligations defaults on any principal or interest 
due and such obligation is guaranteed by Ambac. Additionally, Ambac’s general creditors, other than those specific policy holders which own 
the VIE debt obligations, do not have rights with regard to the assets of the VIEs. Ambac evaluates the net income effects and earnings per 
share effects to determine attributions between Ambac and non-controlling interests as a result of consolidating a VIE. Ambac has determined 
that the net income and earnings per share effect of most consolidated FG VIEs are attributable to Ambac’s interests through financial guarantee 
premium and loss payments with the VIE.

Below is a schedule detailing the change in fair value of the various financial instruments within the consolidated FG VIEs, along with gains 
(losses) from consolidating and deconsolidating FG VIEs, that together comprise Income (loss) on variable interest entities for for the affected 
periods:

Ambac  deconsolidated  one,  two  and  one VIEs  for  the  years  ended  December  31,  2016,  2015  and  2014,  respectively.   These VIEs  were 
deconsolidated as a result of guaranteed bond retirements or financial guarantee policy terminations that eliminated Ambac's controlling 
variable interest in the entities.  The deconsolidations occurring in 2016 and 2014 were related to guaranteed bond retirements which resulted 
in no gain or loss. The gain on deconsolidation in 2015 reflected the excess of fees receivable from a financial guarantee policy termination 
for one VIE, representing Ambac's remaining non-controlling financial interest, over the fair value of net assets of the VIE at deconsolidation.

A subsidiary of Ambac transferred financial assets to two special purpose entities. The business purpose of these entities was to provide certain 
financial guarantee clients with funding for their debt obligations. These special purpose entities were established as separate legal entities, 
demonstrably distinct from Ambac and that Ambac, its affiliates or its agents could not unilaterally dissolve. The permitted activities of these 
entities were contractually limited to purchasing assets from Ambac, issuing MTNs to fund such purchases, executing derivative hedges and 
obtaining financial guarantee policies with respect to indebtedness incurred.  Effective February 17, 2015, one of the special purpose entities 
was liquidated as it no longer had any outstanding liabilities. Ambac has not consolidated these entities because Ambac Assurance’s policies 
issued to these entities have been allocated to the Segregated Account, thereby limiting Ambac’s control over the entities’ most significant 
economic activities. Ambac has elected to account for its equity interest in these entities at fair value under the fair value option in accordance 
with  the  Financial  Instruments Topic  of  the ASC. We  believe  that  the  fair  value  of  the  investments  in  these  entities  provides  for  greater 
transparency for recording profit or loss as compared to the equity method under the Investments – Equity Method and Joint Ventures Topic 
of the ASC. Refer to Note 9. Fair Value Measurements for further information on the valuation technique and inputs used to measure the fair 
value of Ambac’s equity interest in these entities. At December 31, 2016 and 2015 the fair value of these entities are $7,382 and $8,696, 
respectively, and is reported within Other assets on the Consolidated Balance Sheets.

• 

Since their inception, there have been15 individual transactions with these entities, of which 3 transactions remain outstanding as of 
December 31,  2016.  Total  principal  amount  of  debt  outstanding  was  $388,950  and  $454,290  at  December  31,  2016  and  2015, 
respectively. In each case, Ambac sold assets to these entities. The assets are composed of utility obligations with a weighted average 
rating of BBB at December 31, 2016 and weighted average life of 4.9 years.  The purchase by these entities of financial assets was 
financed through the issuance of medium-term notes (“MTNs”), which are cross-collateralized by the purchased assets. The MTNs 
have the same expected weighted average life as the purchased assets. Derivative contracts (interest rate swaps) are used within the 
entities for economic hedging purposes only. Derivative positions were established at the time MTNs were issued to purchase financial 
assets. As of December 31, 2016 Ambac Assurance had financial guarantee insurance policies issued for all assets, MTNs and derivative 
contracts owned and outstanding by the entities.

• 

Insurance premiums paid to Ambac Assurance by these entities are earned in a manner consistent with other insurance policies, over 
the risk period. Additionally, any losses incurred on such insurance policies are included in Ambac’s Consolidated Statements of Total 
Comprehensive Income. Under the terms of an Administrative Agency Agreement, Ambac provides certain administrative duties, 
primarily collecting amounts due on the obligations and making interest payments on the MTNs.

In July 2015, Ambac Assurance entered into a secured borrowing transaction whereby it sold 17 Ambac insured residential mortgage-backed 
securities (the "Securities") and all rights associated therewith as of May 31, 2015, to a Delaware statutory trust (the "Trust") in exchange for 
an equity certificate in the Trust, all financial guarantee claim payments associated with the Securities and cash of $146,000 (prior to expenses 
associated with the transaction).  The Securities had par and fair value of $331,035 and $360,759 as of December 31, 2016, respectively.  
Although the Securities were legally sold to the Trust, the Securities will remain in Invested assets on the Consolidated Balance Sheets.  Refer 
to Note 10. Investments for further discussion of the restrictions on the invested assets.  At the same time, a second Delaware statutory trust 
(the "Issuer"), issued $146,000 of debt securities and used the proceeds, together with an equity certificate of the Issuer, to purchase from the 
Trust a certificate secured by and entitling the Issuer to all principal and interest payments (other than financial guarantee claim payments) on 
the Securities. Interest on the debt securities is payable monthly at an annual rate of one month LIBOR + 2.8% .  Both the Trust and the Issuer 
are consolidated VIEs because Ambac Assurance was involved in their design and holds a significant amount of the beneficial interests issued 
by the VIEs or guaranteed the assets held by the VIEs. VIE debt outstanding to third parties under this secured borrowing transaction had a 
carrying value of $102,403 and $130,571 as of December 31, 2016 and 2015, respectively, and is reported in Long-Term Debt on the Consolidated 
Balance Sheets.

Variable Interests in Non-Consolidated VIEs

On August 28, 2014 Ambac monetized its ownership of the junior surplus note issued to it by the Segregated Account by depositing the junior 
surplus note into a newly formed VIE trust in exchange for cash of $224,262 and a subordinated owner trust certificate (the "Owner Trust 
Certificate"), which represents Ambac's right to residual cash flows from the junior surplus note. The Trust funded the cash portion of its 
purchase of the junior surplus note with proceeds of the private placement of $299,175 face amount of notes to third party investors ("Notes"), 
which amount equates to approximately 80% of par plus accrued and unpaid interest on the junior surplus note.  The Notes have a final maturity 
of August 28, 2039. Interest on the Notes will accrue at 5.1% per annum and compound annually on June 7th of each year up to and including 
the maturity date. Payments on the Notes will be made when and to the extent that the Segregated Account makes payments on the junior 
surplus note. The Notes must be paid in full before any payments will be made on the Owner Trust Certificate. The Notes and Owner Trust 
Certificate are non-recourse to Ambac, Ambac Assurance and the Segregated Account, but are collateralized by the junior surplus note. Ambac 
does not consolidate the VIE. Ambac reports its interest in the VIE as an equity investment within Other investments on the Consolidated 
Balance  Sheets  with  associated  results  from  operations  included  within  Net  investment  income:  Other  investments  on  the  Consolidated 
Statements of Total Comprehensive Income.  The equity investment had a carrying value of $30,003 and $25,339 as of December 31, 2016 
and 2015, respectively.

Pursuant to the Reorganization Plan, 45,000,000 shares of common stock at par value of $0.01 per share and 5,047,138 warrants were issued. 
Warrants entitle such holders to acquire up to 5,047,138 shares of new common stock at an exercise price of $16.67 per share at any time on 
or prior to April 30, 2023. For the years ended December 31, 2016, 2015 and 2014, 136, 740, and 949, warrants, respectively, were exercised, 
resulting in an issuance of 136, 236 and 949 shares of common stock.

On June 30, 2015, the Board of Directors of Ambac authorized the establishment of a warrant repurchase program that permits the repurchase 
of up to $10,000 of warrants.  On November 3, 2016, the Board of Directors of Ambac authorized an additional $10,000 to the warrant 
repurchase program.  As of December 31, 2016, Ambac had repurchased 985,331 warrants at a cost of  $8,092, leaving 4,053,670 warrants 
outstanding, bringing the remaining aggregate authorization to $11,939. 

Basic net income per share is computed by dividing net income attributable to common shareholders by the weighted-average number of 
common shares outstanding and vested restricted stock units. Diluted net income per share is computed by dividing net income attributable 
to common shareholders by the weighted-average number of common shares outstanding plus all potential dilutive common shares outstanding 
during the period.  All potential dilutive common shares outstanding consider common stock deliverable pursuant to warrants issued under 
the  Reorganization  Plan  and  unvested  options,  restricted  stock  units  and  performance  stock  units  granted  under  employee  and  director 
compensation plans.

(1) Gross premium receivable includes premiums to be received in foreign denominated currencies most notably in British Pounds and Euros.  At  December 31, 
2016, 2015 and 2014 premium receivables include British Pounds of $177,878 (£144,393), $226,994 (£154,135) and $275,374 (£176,703), respectively, and 
Euros of $34,866 (€33,108), $43,451 (€40,014) and $74,413 (€61,494), respectively. 

In structured finance transactions, the priority for the payment of financial guarantee premiums to Ambac, as required by the bond indentures 
of the insured obligations, is generally very senior in the waterfall. Additionally, in connection with the allocation of certain liabilities to the 
Segregated Account,  trustees  are  required  under  the  Segregated Account  Rehabilitation  Plan  and  related  court  orders  to  continue  to  pay 
installment premiums, notwithstanding the Segregated Account Rehabilitation Proceedings. In evaluating the credit quality of the premium 
receivables, management evaluates the transaction waterfall structures and the internal ratings of the transactions underlying the premium 
receivables. As of December 31, 2016 and 2015, approximately 25% and 27% of the premium receivables related to transactions with non-
investment grade internal ratings, comprised mainly of non-investment grade RMBS, student loan transactions and lease securitizations, which 
comprised 8%, 3%, and 4% of the total premium receivables at December 31, 2016 and 8%, 5% and 5% of the total premium receivables at 
December 31, 2015, respectively.  At December 31, 2016 and 2015, $9,186 and $15,240 respectively, of premium receivables were deemed 
uncollectable. Past due premiums on policies insuring non-investment grade obligations amounted to less than $500 at December 31, 2016.

(1)  Future premiums to be collected is undiscounted and relates to the discounted premium receivable asset recorded on Ambac's balance sheet.  Future 
premiums to be earned, net of reinsurance relate to the unearned premium liability and deferred ceded premium asset recorded on Ambac’s balance sheet. 
The use of contractual lives for many bond types which do not have homogeneous pools of underlying collateral is required in the calculation of the 
premium receivable as described in Note 2. Basis of Presentation and Significant Accounting Policies, results in a different premium receivable balance 
than if expected lives were considered. If installment paying policies are retired or prepay early, premiums reflected in the premium receivable asset and 
amounts reported in the above table for such policies may not be collected.  Future premiums to be earned also considers the use of contractual lives for 
many bond types which do not have homogeneous pools of underlying collateral, which results in different unearned premium than if expected lives were 
considered.  If those bonds types are retired early, premium earnings may be negative in the period of call or refinancing.

Loss and Loss Expense Reserves:

A loss reserve is recorded on the balance sheet on a policy-by-policy basis as further described in Note 2. Basis of Presentation and Significant

related to ceded reinsurance.

(2)  Ambac records the impact of estimated recoveries related to securitized loans in RMBS transactions that breached certain representations and warranties 
within losses and loss expenses (benefit).  The losses and loss expense (benefit) incurred associated with changes in estimated representation and warranties 
for the year ended December 31, 2016, 2015, and 2014 was $(71,369), $(303,633) and $(481,669), respectively.

(3)  Represents reinsurance recoverable on future loss and loss expenses.  Additionally, the Balance Sheet line "Reinsurance recoverable on paid and unpaid 
losses" includes reinsurance recoverables (payables) of $(349), $(60) and $(517) as of December 31, 2016, 2015 and 2014, respectively, related to previously 
presented loss and loss expenses and subrogation.

(4) 

Includes Euro denominated gross loss and loss expense reserves of $21,375 (€20,297), $19,019 (€17,515) and $16,094 (€13,300) at December 31, 2016, 
2015 and 2014, respectively.

For 2016, the net positive development in prior years was primarily the result of lower projected losses in the RMBS portfolio due to improved 
deal performance and higher representation and warranty subrogation recoveries, and the impact of executed commutations in the student loan 
portfolio.  This is partially offset by negative development in Puerto Rico, the adverse impact of foreign currency rate movements on the 
Ambac UK portfolio and interest accrued on Deferred Amounts.

For 2015, the net positive development in prior years was primarily due to increases in our estimate of RMBS R&W recoveries as a result of 
continuous efforts and ongoing assessments of the value of our claims, as well as declines in interest rates on RMBS, student loans and Ambac 
UK credits, reduced claims expectations for an Ambac UK transaction resulting from proactive remediation efforts and the impact of executed 
commutations in the student loan portfolio.  This was partially offset by  negative development in Puerto Rico, the adverse impact of foreign 
currency rate movements on the Ambac UK portfolio and interest accrued on Deferred Amounts.

For 2014, the net positive development in prior years was due to improved performance in all sectors, including RMBS, Student Loans, 
international, municipal and other structured finance, partially offset by the addition of accrued interest on Deferred Amounts pursuant to the 
amended Segregated Account Rehabilitation Plan.

(1)  Gross undiscounted claim liability includes unpaid claims, including accrued interest on Deferred Amounts, on policies allocated to the Segregated Account 

and Ambac's estimate of expected future claims.

(2)  RMBS subrogation represents Ambac’s estimate of subrogation recoveries from RMBS transaction sponsors for R&W breaches.

(3)  Other subrogation primarily represents subrogation related to excess spread or other contractual cash flows on public finance and structured finance 

transactions, including RMBS.

(4)  Reinsurance recoverable reported on Balance Sheet includes reinsurance recoverables of $44,059 related to future loss and loss expenses and $(60) related 

to presented loss and loss expenses and subrogation.

Ambac  records  estimated  subrogation  recoveries  for  breaches  of  representations  and  warranties  (R&W)  by  sponsors  of  certain  RMBS 
transactions.  Prior to the June 30, 2014 reporting period, Ambac utilized the Adverse and Random Sample approaches to estimate R&W 
subrogation  recoveries  for  certain  RMBS  transactions.  For  a  discussion  of  these  subrogation  recovery  approaches,  see  Note  2.  Basis  of 
Presentation and Significant Accounting Policies. Beginning with the June 30, 2014 reporting period, as a result of gaining further access to 
loan files, the Random Sample approach has been utilized for all transactions which were previously evaluated using the Adverse Sample 
approach.  R&W subrogation may include estimates of potential sponsor settlements, but have not been subject to a sampling approach.  
However, such estimates are not material to Ambac’s financial results and therefore are included in the Random Sample section of this table.  

Ambac  has  recorded  RMBS  subrogation  recoveries  of  $1,907,035,  ($1,878,740  net  of  reinsurance)  and  $2,829,575,  ($2,800,149  net  of 
reinsurance) at December 31, 2016 and 2015, respectively. The balance of RMBS subrogation recoveries and the related loss reserves, using 
Random Samples as the estimation approach, at December 31, 2016 and 2015, are as follows:

(1) 

Includes unpaid RMBS claims, including accrued interest on Deferred Amounts, on policies allocated to the Segregated Account.

(2)  The amount of recorded subrogation recoveries related to each securitization is limited to ever-to-date paid and unpaid losses plus the present value of 
expected cash flows for each policy. To the extent losses have been paid but not yet fully recovered, the recorded amount of RMBS subrogation recoveries 
may exceed the sum of the unpaid claims and the present value of expected cash flows for a given policy. The net cash inflow for these policies is recorded 
as a “Subrogation recoverable” asset. For those transactions where the subrogation recovery is less than the sum of unpaid claims and the present value 
of expected cash flows, the net cash outflow for these policies is recorded as a “Loss and loss expense reserves” liability.

(3)  The sponsor’s repurchase obligation may differ depending on the terms of the particular transaction and the status of the specific loan, such as whether it 
is performing or has been liquidated or charged off. The estimated subrogation recovery for these transactions is based primarily on loan level data provided 
through trustee reports received in the normal course of our surveillance activities or provided by the sponsor. While this data may not include all the 
components of the sponsor’s contractual repurchase obligation we believe it is the best information available to estimate the subrogation recovery.

(1)  Sponsor actions include loan repurchases, direct payments to Ambac and other contributions from sponsors.  In January 2016, Ambac Assurance settled 
its RMBS-related disputes and litigation against JP Morgan Chase & Co. and certain of its affiliates (collectively "JP Morgan"). Pursuant to the settlement, 
JP Morgan paid Ambac Assurance $995,000 in cash in return for releases of all of Ambac Assurance's claims against JP Morgan arising from certain 
RMBS transactions insured by Ambac Assurance. Ambac Assurance also agreed to withdraw its objections to JP Morgan's global RMBS settlement with 
RMBS trustees.

Assumed Reinsurance: 

Assumed par outstanding was $243,700 and $245,900 at December 31, 2016 and 2015, respectively. On March 24, 2010, all assumed reinsurance 
agreements with third parties were allocated to the Segregated Account, which will not allow for cancellations without the approval of the 
Rehabilitator. 

Ceded Reinsurance: 

Ambac Assurance has reinsurance in place pursuant to surplus share treaty and facultative reinsurance agreements. The reinsurance of risk 
does not relieve Ambac Assurance of its original liability to its policyholders. In the event that any of Ambac Assurance’s reinsurers are unable 
to meet their obligations under reinsurance contracts, Ambac Assurance would, nonetheless, be liable to its policyholders for the full amount 
of its policy. 

Ambac Assurance’s reinsurance assets, including deferred ceded premiums and reinsurance recoverables on losses amounted to $100,042 at 
December 31, 2016. Credit exposure existed at December 31, 2016 with respect to reinsurance recoverables to the extent that any reinsurer 
may not be able to reimburse Ambac Assurance under the terms of these reinsurance arrangements. At December 31, 2016, there were ceded 
reinsurance balances payable of $42,529 offsetting this credit exposure. 

To minimize its credit exposure to losses from reinsurer insolvencies, Ambac Assurance (i) is entitled to receive collateral from its reinsurance 
counterparties in certain reinsurance contracts; and (ii) has certain cancellation rights that can be exercised by Ambac Assurance in the event 
of rating agency downgrades of a reinsurer (among other events and circumstances).  Ambac Assurance held letters of credit and collateral 
amounting to $122,912 from its reinsurers at December 31, 2016.  As of December 31, 2016, the aggregate amount of insured par ceded by 
Ambac Assurance to reinsurers under reinsurance agreements was $7,027,000 with the largest reinsurer accounting for $6,086,000 or 7.0%
of gross par outstanding at December 31, 2016. The following table represents the percentage ceded to reinsurers and reinsurance recoverable 
at December 31, 2016 and its rating levels obtained from each reinsurers website as of February 24, 2017:

Insurance intangible asset:

The  insurance  intangible  amortization  expense  is  included  in  insurance  intangible  amortization  on  the  Consolidated  Statements  of Total 
Comprehensive Income.  For the years ended December 31, 2016, 2015 and 2014, the insurance intangible amortization expense was $174,608, 
$169,557 and $151,830, respectively.  As of December 31, 2016 and 2015, the gross carrying value of the insurance intangible asset was 
$1,534,419 and $1,626,566, respectively.  Accumulated amortization of the insurance intangible asset was $572,339 and $414,454, as of 
December 31, 2016 and 2015, respectively, resulting in a net insurance intangible asset of $962,080 and $1,212,112, respectively.

8.        INSURANCE REGULATORY RESTRICTIONS 

United States

Ambac Assurance (exclusive of the Segregated Account which is under the control of OCI via the Segregated Account Rehabilitation Plan 
and Segregated Account Rehabilitation Proceedings) and Everspan are subject to the insurance laws and regulations of each jurisdiction in 
which it is licensed, some of which are described below. Failure to comply with applicable insurance laws and regulations (including, without 
limitation, minimum surplus requirements, aggregate risk limits and single risk limits) could expose Ambac Assurance or Everspan to fines, 
the loss or suspension of insurance licenses in certain jurisdictions, the imposition of orders by regulators with respect to the conduct of business 
by Ambac Assurance or Everspan and/or the inability to pay dividends, all of which could have an adverse impact on our business results.

AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements
(Dollar Amounts in Thousands, Except Share Amounts)

New York’s comprehensive financial guarantee insurance law defines the scope of permitted financial guarantee insurance and governs the 
conduct of business of all financial guarantors licensed to do business in New York, including Ambac Assurance and Everspan. The New York 
financial guarantee insurance law also establishes single risk and aggregate limits with respect to insured obligations insured by financial 
guarantee insurers. Such single risk limits are specific to the type of insured obligation (for example, municipal or asset-backed). Under the 
aggregate limits, policyholders’ surplus and contingency reserves must at least equal a percentage of aggregate net liability that is equal to the 
sum of various percentages of aggregate net liability for various categories of specified obligations. At December 31, 2016, Ambac Assurance 
is in compliance with applicable aggregate risk limits but not in compliance with applicable single risk limits. Through run-off of the portfolio, 
Ambac Assurance will continue to seek the reduction in its exposure to maintain its compliance with applicable single and aggregate risk 
limits, but may not be able to do so. Everspan is in compliance with all of such limits. 

Ambac Assurance’s statutory financial statements are prepared on the basis of accounting practices prescribed or permitted by Wisconsin 
Insurance law and OCI actions thereunder. A Wisconsin insurance company uses such statutory accounting practices prescribed or permitted 
by the State of Wisconsin for determining and reporting its financial condition and results of operations, including for determining its solvency 
under Wisconsin Insurance Law. The State of Wisconsin has adopted the applicable National Association of Insurance Commissioners (“NAIC”) 
accounting  practices  and  procedures  manual  (“NAIC  SAP”)  as  a  component  of  prescribed  practices  by  the  State  of Wisconsin.   Ambac 
Assurance’s statutory policyholder surplus was $976,477 at December 31, 2016 as compared to $624,795 as of December 31, 2015. Statutory 
policyholder surplus differs from stockholders’ equity determined under GAAP principally due to statutory accounting rules that treat loss 
reserves, investments, consolidation of subsidiaries and variable interest entities, premiums earned and surplus notes differently. 

The OCI has prescribed or permitted accounting practices for Ambac Assurance. As a result of the prescribed and permitted practices discussed 
below, Ambac Assurance’s statutory surplus at December 31, 2016 and 2015 was higher by $17,290 and $21,260, respectively, than if Ambac 
Assurance had reported such amounts in accordance with NAIC SAP. 

Prescribed Accounting Practices:

•  OCI has prescribed an accounting practice that differs from NAIC SAP. Paragraph 8 of Statement of Statutory Accounting Principles 
No. 60 “Financial Guaranty Insurance” (“SSAP 60”) allows for a deduction from loss reserves for the time value of money by application 
of a discount rate equal to the average rate of return on the admitted assets of the financial guaranty insurer as of the date of the 
computation of the reserve. The discount rate shall be adjusted at the end of each calendar year. Additionally, in accordance with 
paragraph 13.e of Statutory Accounting Principles No. 97 "Investments in Subsidiary, Controlled and Affiliated Entities" and paragraph 
8 of Statutory Accounting Principles No. 5R “Liabilities, Contingencies and Impairments of Assets - Revised”, Ambac Assurance 
records probable losses on its subsidiaries for which it guarantees their obligations. Ambac also discounts probable losses on guarantees 
of subsidiary obligations using a discount rate equal to the average rate of return on its admitted assets.  Ambac Assurance’s average 
rates of return on its admitted assets at December 31, 2016 and 2015 were 7.63% and 8.06%, respectively. OCI has directed Ambac 
Assurance to utilize a prescribed discount rate of 5.10% for the purpose of discounting both its loss reserves and its estimated impairment 
losses on subsidiary guarantees. 

•  OCI has prescribed an additional accounting practice that differs from NAIC SAP. Paragraph 4 of Statement of Statutory Accounting 
Principles No. 41 “Surplus Notes” (“SSAP 41”) states that proceeds received by the issuer of surplus notes must be in the form of cash 
or other admitted assets having readily determinable values and liquidity satisfactory to the commissioner of the state of domicile. 
Under the statutory accounting principles as generally applied, surplus notes issued in conjunction with commutations or the settlement 
of claims would be valued at zero upon issuance pursuant to paragraph 4, SSAP 41. OCI has directed Ambac Assurance to record 
surplus notes issued in connection with commutations or the settlement of claims at full par value upon issuance as in these instances 
the surplus notes did not represent a contribution of capital, but rather a distribution of value from the common and preferred shareholders 
of Ambac Assurance. The surplus notes issued in connection with commutations or settlement of claims has a claim against surplus 
senior to the preferred and common shareholders. 

•  OCI had extended the preceding prescribed practice related to surplus notes to the evaluation of other-than-temporary impairments for 
Ambac Assurance guaranteed securities held in the investment portfolio.  Paragraph 35 of Statement of Statutory Accounting Principles 
No. 43R ”Loan-backed and Structured Securities” states that when an other-than-temporary impairment has occurred, the amount of 
the other-than-temporary impairment recognized as a realized loss shall equal the difference between the investment’s amortized cost 
basis and the present value of cash flows expected to be collected, discounted at the loan-backed or structured security’s effective 
interest rate. Under NAIC SAP, the present value of cash flows expected to be collected should include the fair value of surplus notes 
received from the Segregated Account, as required under the originally confirmed Segregated Account Rehabilitation Plan.  OCI had 
prescribed an accounting practice that differed from NAIC SAP and has directed Ambac Assurance to utilize par value rather than fair 
value of these surplus notes in this computation.  As a result of the amended Segregated Account Rehabilitation Plan becoming effective 
on June 12, 2014, this prescribed practice is no longer applicable.  Ambac Assurance received a new prescribed practice from OCI 
with regard to the carrying value of investments in Ambac Assurance insured securities with policies that were allocated to the Segregated 
Account.  The new prescribed practice, effective beginning June 11, 2014, exempts Ambac Assurance from evaluating such investments 
for other than temporary impairments and requires  all such investments be reported at amortized cost regardless of its NAIC risk 
designation. This accounting determination is intended to recognize  that Ambac Assurance continues to maintain statutory loss reserves

AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements
(Dollar Amounts in Thousands, Except Share Amounts)

without adjustment for the economic effects of its ownership of the insured investment securities, improve transparency to the users 
of the statutory financial statements and to minimize operational risks.  

•  OCI has prescribed an accounting practice related to the total liabilities and total surplus of the Segregated Account that are reported 
as discrete components of Ambac Assurance’s liabilities and surplus reported in Ambac Assurance’s statutory basis financial statements. 
Pursuant to this prescribed practice, the results of the Segregated Account are not included in Ambac Assurance’s financial statements 
if Ambac Assurance’s surplus is (or would be) less than the Minimum Surplus Amount. As long as the surplus as regards to policyholders 
is not less than the Minimum Surplus Amount, payments by Ambac Assurance to the Segregated Account under the Reinsurance 
Agreement are not capped.

Permitted Accounting Practices:

•  Wisconsin accounting practices for changes to contingency reserves differ from NAIC SAP. Under NAIC SAP, contributions to and 
releases from the contingency reserve are recorded via a direct charge or credit to surplus. Under the Wisconsin Administrative Code, 
contributions to and releases from the contingency reserve are to be recorded through underwriting income. Ambac Assurance received 
permission from OCI to record contributions to and releases from the contingency reserve and the related tax and loss bond impact, 
in accordance with NAIC SAP. 

•  Ambac Assurance received permission from OCI to report investment holdings of Ambac Assurance insured securities, with coverage 
under financial guaranty policies that have been allocated to the Segregated Account, as a separate invested asset on the balance sheet 
rather than combined with other bond investments. This permitted practice only impacts the balance sheet classification and has no 
impact on the valuation of the securities to which it applies or to statutory surplus. 

United Kingdom 

The Prudential Regulatory Authority (“PRA”) and Financial Conduct Authority (“FCA”) (and their predecessor regulator the Financial Services 
Authority (“FSA”)) have exercised significant oversight of Ambac UK since 2008, after Ambac, Ambac Assurance and Ambac UK began 
experiencing financial stress.  In 2009, Ambac UK’s license to write new business was curtailed by the FSA and the insurance license was 
limited to undertaking only run-off related activity. As such, Ambac UK is authorized to run-off its credit, suretyship and financial guarantee 
insurance portfolio in the United Kingdom, and to do the same through a branch in Milan, Italy, and a number of other European Union (“EU”) 
countries. EU legislation has allowed Ambac UK to conduct business in EU states other than the United Kingdom through a “passporting” 
arrangement, which eliminates the necessity of additional licensing or authorization in those other EU jurisdictions. 

The PRA and FCA is the dual statutory regulator responsible for regulating the financial services industry in the United Kingdom, with the 
purpose of maintaining confidence in the U.K. financial system, providing public understanding of the system, securing the proper degree of 
protection for consumers and helping to reduce financial crime. In addition, the regulatory regime in the United Kingdom must comply with 
certain EU legislation binding on all EU member states. 

The PRA requires that non-life insurance companies such as Ambac UK maintain a margin of solvency at all times in respect of the liabilities 
of the insurance company, the calculation of which depends on the type and amount of insurance business a company writes. These solvency 
requirements were amended on January 1, 2016 in order to implement the European Union's "Solvency II" directive on risk-based capital. 
Notwithstanding the foregoing, Ambac UK is deficient in terms of compliance with currently applicable regulatory capital requirements under 
Solvency II directive. The PRA and FCA are aware of the same, and dialogue between Ambac UK management and its regulators remains 
ongoing with respect to options for addressing the shortcoming, although such options remain few.

Dividend Restrictions, Including Contractual Restrictions 

Due to losses experienced by Ambac Assurance, Ambac Assurance has been unable to pay common dividends to Ambac since 2008 and will 
be unable to pay common dividends in 2017 without the prior consent of the OCI, which is unlikely.  Ambac Assurance’s ability to pay 
dividends is further restricted by the Settlement Agreement (as described below), by the terms of its AMPS (as described below) and by certain 
covenants made for the benefit of the Segregated Account. See Note 1. Background and Business Description for further information. 

Subject  to  the  foregoing,  pursuant  to  the Wisconsin  Insurance  Laws, Ambac Assurance  and  Everspan  may  declare  dividends,  subject  to 
restrictions in their respective articles of incorporation, provided that, after giving effect to the distribution, such dividends would not violate 
certain statutory equity, solvency, income and asset tests. Board action authorizing a shareholder distribution by Ambac Assurance or Everspan 
(other than stock dividends) must be reported to the OCI at least 30 days prior to payment, unless the distribution is no more than 15% larger 
than for the corresponding period in the previous year.  In addition, Wisconsin Insurance Laws restrict the payment of extraordinary dividends, 
which is any distribution which, together with distributions in the prior 12 months, is greater than the lesser of (a) 10% of policyholders’ 
surplus as of the preceding December 31, and (b) the greater of (i) statutory net income (loss) for the calendar year preceding the date of the 
dividend, minus realized capital gains for that calendar year or (ii) the aggregate of statutory net income (loss) for three calendar years preceding 
the date of the dividend, minus realized capital gains for those calendar years and minus dividends paid or credited within the first two of the 
three preceding calendar years. In connection with the termination of reinsurance contracts, OCI requires adjustments to the dividend calculation 

| Ambac Financial Group, Inc.   116   2016 FORM 10-K |

 
 
 
AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements
(Dollar Amounts in Thousands, Except Share Amounts)

for any surplus or net income gains recognized.  Extraordinary dividends must be reported to OCI at least 30 days prior to payment and are 
subject to disapproval by the OCI. 

UK law prohibits Ambac UK from declaring a dividend to its shareholders unless it has “profits available for distribution.” The determination 
of whether a company has profits available for distribution is based on its accumulated realized profits less its accumulated realized losses. 
While the UK insurance regulatory laws impose no statutory restrictions on a general insurer’s ability to declare a dividend, the PRA’s and 
FCA’s capital requirements in practice act as a restriction on the payment of dividends. Further, the FSA amended Ambac UK’s license in 
2010 such that the PRA must specifically approve (“non-objection”) any transfer of value and/or assets from Ambac UK to Ambac Assurance 
or any other Ambac group company, other than in respect of certain disclosed contracts between the two parties (such as in respect of a 
management services agreement between Ambac Assurance and Ambac UK). Ambac UK is not expected to pay any dividends to Ambac 
Assurance for the foreseeable future.

Pursuant to the Settlement Agreement Ambac Assurance may not make any “Restricted Payment” (which includes dividends from Ambac 
Assurance to Ambac) in excess of $5,000 in the aggregate per annum, other than Restricted Payments from Ambac Assurance to Ambac in 
an amount up to $7,500 per annum solely to pay operating expenses of Ambac. Concurrent with making any such Restricted Payment, a pro 
rata amount of the surplus notes issued by Ambac Assurance under the Settlement Agreement would also need to be redeemed at par. 

Under the terms of Ambac Assurance’s Auction Market Preferred Shares (“AMPS”), dividends may not be paid on the common stock of 
Ambac Assurance unless all accrued and unpaid dividends on the AMPS for the then current dividend period have been paid, provided, that 
dividends on the common stock may be made at all times for the purpose of, and only in such amounts as are necessary for, enabling Ambac 
(i) to service its indebtedness for borrowed money as such payments become due or (ii) to pay its operating expenses. If dividends are paid 
on the common stock as provided in the prior sentence, dividends on the AMPS become cumulative until the date that all accumulated and 
unpaid dividends have been paid on the AMPS. 

9.        FAIR VALUE MEASUREMENTS 

The Fair Value Measurement Topic of the ASC establishes a framework for measuring fair value and disclosures about fair value measurements.

Fair Value Hierarchy:

The Fair Value Measurement Topic of the ASC specifies a fair value hierarchy based on whether the inputs to valuation techniques used to 
measure  fair  value  are  observable  or  unobservable.  Observable  inputs  reflect  market  data  obtained  from  independent  sources,  while 
unobservable inputs reflect Company-based assumptions. The fair value hierarchy prioritizes model inputs into three broad levels as follows:

Level 1

Level 2

Quoted prices for identical instruments in active markets. Assets and liabilities classified as Level 1 include US Treasury and 
other foreign government obligations traded in highly liquid and transparent markets, exchange traded futures contracts, variable 
rate demand obligations and money market funds.

Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are 
not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active 
markets. Assets and liabilities classified as Level 2 generally include direct investments in fixed income securities representing 
municipal, asset-backed and corporate obligations, most financial services derivatives, and most long-term debt of variable 
interest entities consolidated under the Consolidation Topic of the ASC. 

Level 3 Model derived valuations in which one or more significant inputs or significant value drivers are unobservable. This hierarchy 
requires the use of observable market data when available. Assets and liabilities classified as Level 3 include credit derivative 
contracts written as part of the financial guarantee business, certain financial services interest rate swap contracts, equity 
interests in Ambac sponsored special purpose entities and certain investments in fixed income securities. Additionally, Level 
3 assets and liabilities generally include fixed income securities, loan receivables, and certain long-term debt of variable interest 
entities consolidated under the Consolidation Topic of the ASC.

Determination of Fair Value:

When available, Ambac uses quoted active market prices specific to the financial instrument to determine fair value, and classifies such items 
within Level 1. Because many fixed income securities do not trade on a daily basis, pricing sources apply available market information through 
processes such as matrix pricing to determine fair value. In those cases, the items are classified within Level 2. If quoted market prices are 
not available, fair value is based upon models that use, where possible, current market-based or independently-sourced market parameters. 
Items valued using valuation models are classified according to the lowest level input or value driver that is significant to the valuation. Thus, 
an item may be classified in Level 3 even though there may be significant inputs that are readily observable. 

The determination of fair value for financial instruments categorized in Level 2 or 3 involves significant judgment due to the complexity of 
factors contributing to the valuation. Third-party sources from which we obtain independent market quotes also use assumptions, judgments 
and estimates in determining financial instrument values and different third parties may use different methodologies or provide different prices 
for securities. In addition, the use of internal valuation models may require assumptions about hypothetical or inactive markets. As a result of 
these factors, the actual trade value of a financial instrument in the market, or exit value of a financial instrument position by Ambac, may be 
significantly different from its recorded fair value. 

Ambac’s financial instruments carried at fair value are comprised of investments in fixed income securities, equity interests in pooled investment 
funds, derivative instruments, variable interest entity assets and liabilities and equity interests in Ambac sponsored special purpose entities. 
Valuation of financial instruments is performed by Ambac’s finance group using methods approved by senior financial management with 
consultation from risk management and portfolio managers as appropriate. Preliminary valuation results are discussed with portfolio managers 
quarterly to assess consistency with market transactions and trends as applicable. Market transactions such as trades or negotiated settlements 
of similar positions, if any, are reviewed quarterly to validate fair value model results. However many of the financial instruments valued 
using significant unobservable inputs have very little or no observable market activity. Methods and significant inputs and assumptions used 
to determine fair values across portfolios are reviewed quarterly by senior financial management. Other valuation control procedures specific 
to particular portfolios are described further below. 

We reflect Ambac’s own creditworthiness in the fair value of financial liabilities by including a credit valuation adjustment (“CVA”) in the 
determination of fair value. A decline (increase) in Ambac’s creditworthiness as perceived by market participants will generally result in a 
higher (lower) CVA, thereby lowering (increasing) the fair value of Ambac’s financial liabilities as reported. 

Fixed Income Securities:

The fair values of fixed income investment securities are based primarily on market prices received from dealer quotes or alternative pricing 
sources with reasonable levels of price transparency. Such quotes generally consider a variety of factors, including recent trades of the same 
and similar securities. For those fixed income investments where quotes were not available or cannot be reasonably corroborated, fair values 
are based on internal valuation models. Key inputs to the internal valuation models generally include maturity date, coupon and yield curves 
for asset-type and credit rating characteristics that closely match those characteristics of the specific investment securities being valued. Longer 
(shorter) expected maturities or higher (lower) yields used in the valuation model will, in isolation, result in decreases (increases) in fair value. 
Generally, lower credit ratings or longer expected maturities will be accompanied by higher yields used to value a security. Certain investments 
in Ambac insured securities for which projected cash flows consist solely of Deferred Amounts and interest thereon, are internally valued 
based upon the valuation of Ambac Assurance's surplus notes.  At December 31, 2016, approximately 5%, 82%, and 13% of the investment 
portfolio (excluding variable interest entity investments) was valued using dealer quotes, alternative pricing sources with reasonable levels of 
price transparency and internal valuation models, respectively. At December 31, 2015, approximately 9%, 82%, and 9% of the investment 
portfolio (excluding variable interest entity investments) was valued using dealer quotes, alternative pricing sources with reasonable levels of 
price transparency and internal valuation models, respectively.

Ambac performs various review and validation procedures to quoted and modeled prices for fixed income securities, including price variance 
analyses, missing and static price reviews, overall valuation analyses by senior traders and finance managers and reviews associated with our 
ongoing impairment analysis. Unusual prices identified through these procedures will be evaluated further against additional market data (if 
available) and/or internally modeled prices, and the pricing source values will be challenged as necessary. Price challenges generally result 
in the use of the pricing source’s quote as originally provided or as revised by the source following their internal diligence process. A price 
challenge may result in a determination by either the pricing source or Ambac management that the pricing source cannot provide a reasonable 
value for a security or cannot adequately support a quote, in which case Ambac would resort to using either other quotes or internal models. 
Results of price challenges are reviewed by senior traders and finance managers. 

Information about the valuation inputs for fixed income securities classified as Level 3 is included below: 

Residential mortgage-backed securities:  These securities are guaranteed under policies that are subject to the Segregated Account Rehabilitation 
Plan and have projected future cash flows consisting solely of Deferred Amounts under such policies including interest thereon.  The fair value 
of such securities classified as Level 3 was $696,713 and $488,884 at December 31, 2016 and 2015, respectively.  Fair value was calculated 
based on the valuation of Ambac Assurance surplus notes which, under the terms of the Segregated Account Rehabilitation Plan, are to be 
redeemed in proportion with the payment of Deferred Amounts on or about the dates when such payments are made.   Refer to Note 1.

Segregated Account policy claims and surplus note redemptions. 

Other asset-backed securities:  These securities are a subordinated tranche of a resecuritization collateralized by Ambac-insured military 
housing bonds.  The fair value of such securities classified as Level 3 was $65,990 and $0 at December 31, 2016 and 2015, respectively.  
Fair value was calculated using a discounted cash flow approach with expected future cash flows discounted using a yield consistent with 
the security type and rating.  Significant inputs for the valuation at December 31, 2016 include the following weighted averages:

a.  Coupon rate:

5.93%

b.  Average Life:

17.74 years

c.  Yield:

13.5%

Other Investments:

Other investments primarily relate to investments in pooled investment funds.  The fair value of pooled investment funds is determined using 
dealer quotes or alternative pricing sources when such investments have readily determinable fair values.  When fair value is not readily 
determinable, pooled investment funds are valued using the net asset value (“NAV”) per share as a practical expedient as permitted under the 
Fair Value Measurement Topic of the ASC.  Below is additional information about such investments in pooled funds that are reported at fair 
value  using NAV as a practical expedient.  There are no unfunded commitments applicable to any of these investments for the periods disclosed.

(1)    Investments consist of UK property to generate income and capital growth.

(2)    Investments seek diversified exposure to hedge fund core strategies to produce high risk-adjusted returns, with low long-term correlation to traditional 

markets and with targeted volatility levels. Funds may have the right to defer redemptions under certain circumstances.

(3)    This class of funds includes investments in a range of instruments including leveraged loans, CLOs, asset-backed securities and floating rate notes to 
generate income and capital appreciation.  Funds with less frequent redemption periods limit redemptions to as little as 15% per period.  Funds with a 
same day redemption notice period are redeemable only weekly, while funds that may be redeemed any business day have notice periods of 15-30 days. 

(4)   This class seeks to obtain high long-term total return through investments with low liquidity and defined terms, resulting in expected capital distributions 

to subscribers between 2020 and 2023.   Redemptions cannot occur prior to the expiration of the investment lock-up period in May 2018.

Other investments also includes Ambac's interest in a non-consolidated VIE, which is carried under the equity method.  Valuation of this 
equity interest is internally calculated using a discounted cash flow approach and is classified as Level 3.

Derivative Instruments:

Ambac’s derivative instruments primarily comprise interest rate and credit default swaps, and exchange traded futures contracts. Fair value 
is determined based upon market quotes from independent sources, when available. For centrally cleared interest rate swaps, valuations are 
determined using quotes from the central counterparty.  When independent quotes are not available, fair value is determined using valuation 
models. These valuation models require market-driven inputs, including contractual terms, credit spreads and ratings on underlying referenced 
obligations, yield curves and tax-exempt interest ratios. The valuation of certain interest rate as well as all credit derivative contracts also 
require the use of data inputs and assumptions that are determined by management and are not readily observable in the market. Under the 
Fair Value Measurement Topic of the ASC, Ambac is required to consider its own credit risk when measuring the fair value of derivative and 
other liabilities. The fair value of credit derivative liabilities was reduced by $1,924 and $10,124 at December 31, 2016 and 2015, as a result 
of incorporating a CVA into the valuation model for these transactions. Interest rate swaps and other derivative liabilities may also require an 
adjustment to fair value to reflect Ambac’s credit risk. Derivative liabilities were reduced by $44,943 and $78,728 at December 31, 2016 and 
2015, as a result of Ambac CVA adjustments to derivative contracts other than credit derivatives. Additional factors considered in estimating 
the amount of any Ambac CVA on such contracts include collateral posting provisions, right of set-off with the counterparty, the period of 
time remaining on the derivatives and the pricing of recent terminations.

As described further below, certain valuation models require other inputs that are not readily observable in the market. The selection of a 
model to value a derivative depends on the contractual terms of, and specific risks inherent in the instrument as well as the availability of 
pricing information in the market.

AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES
Notes to Consolidated Financial Statements
(Dollar Amounts in Thousands, Except Share Amounts)

Derivatives that are less complex may be valued primarily by reference to interest rates and yield curves that are observable and regularly 
quoted, such as interest rate swaps, we generally utilize vendor-developed models.   These models provide the net present value of the derivatives 
based on contractual terms and observable market data. Downgrades of Ambac Assurance, as guarantor of the financial services derivatives, 
have increased collateral requirements and triggered termination provisions in certain interest rate swaps. Termination activity since the initial 
rating downgrades of Ambac Assurance provided additional information about the replacement and/or exit value of certain financial services 
derivatives, which has been incorporated into the fair value of these derivatives as appropriate. Generally, the need for counterparty (or Ambac) 
CVAs is mitigated by the existence of collateral posting agreements under which adequate collateral has been posted. Derivative contracts 
entered into with financial guarantee customers are not typically subject to collateral posting agreements. Counterparty credit risk related to 
such customer derivative assets is included in our fair value adjustments. 

For derivatives that do not trade, or trade in less liquid markets such as credit derivatives, an internal model is generally used because such 
instruments tend to be unique, contain complex or heavily modified and negotiated terms, and pricing information is not readily available in 
the  market.  Derivative  fair  value  models  and  the  related  assumptions  are  continuously  re-evaluated  by  management  and  enhanced,  as 
appropriate, based on improvements in modeling techniques. Ambac has not made any significant changes to its modeling techniques or related 
model inputs for the periods presented. 

Credit Derivatives (“CDS”):

Fair value of Ambac’s CDS is determined using internal valuation models and represents the net present value of the difference between the 
fees Ambac originally charged for the credit protection and our estimate of what a financial guarantor of comparable credit quality would 
hypothetically charge to provide the same protection at the balance sheet date. Ambac competed in the financial guarantee market, which 
differs from the credit markets where Ambac-insured obligations may trade. As a financial guarantor, Ambac assumes only credit risk; we do 
not assume other risks and costs inherent in direct ownership of the underlying reference securities. Additionally, as a result of having the 
ability to influence our CDS counterparty in certain investor decisions, financial guarantors generally have the ability to actively remediate 
the credit, potentially reducing the loss given a default. Financial guarantee contracts, including CDS, issued by Ambac and its competitors 
are typically priced to capture some portion of the spread that would be observed in the capital markets for the underlying (insured) obligation. 
Such pricing was well established by historical financial guarantee fees relative to capital market spreads as observed and executed in competitive 
markets, including in financial guarantee reinsurance and secondary market transactions. Because of this relationship and in the absence of 
severe credit deterioration, changes in the fair value of our credit default swaps will generally be less than changes in the fair value of the 
underlying reference obligations. 

Key variables used in our valuation of substantially all of our credit derivatives include the balance of unpaid notional, expected term, fair 
values of the underlying reference obligations, reference obligation credit ratings, assumptions about current financial guarantee CDS fee 
levels relative to reference obligation spreads and the CVA applied against Ambac Assurance liabilities by market participants. Notional 
balances, expected remaining term and reference obligation credit ratings are monitored or determined by Ambac’s Portfolio Risk Management 
group. Fair values of the underlying reference obligations are obtained from broker quotes when available, or are estimated internally. Implicit 
in the fair values we obtain on the underlying reference obligations are the market’s assumptions about default probabilities, default timing, 
correlation, recovery rates and collateral values. 

Fair values of  reference obligations named in our CDS contracts are an input to determine the estimated fair value of the CDS and are 
determined using the same methodologies used to value Ambac’s fixed income securities in its investment portfolio as described above. CDS 
reference obligation fair values are based on market prices received from dealer quotes or alternative pricing sources with reasonable levels 
of price transparency. When quotes for reference obligations are not available or cannot be reasonably corroborated, reference obligation prices 
used  in  the  valuation  model  are  estimated  internally  based  on  available  market  prices  or  spreads  for  securities  or  indices  with  similar 
characteristics such as underlying collateral, credit rating and expected life.   Internal estimates may also consider historical quotes on the 
reference obligation, updated for changes in market factors and  security specific developments such as credit rating changes.  Reference 
obligation prices derived internally as described above were used in the determination of CDS fair values related to transactions representing 
0% of CDS gross par outstanding and 0% of the CDS derivative liability as of December 31, 2016.

Ambac’s CDS fair value calculations are adjusted for changes in our estimates of expected loss on the reference obligations and observable 
changes in financial guarantee market pricing. If no adjustment is considered necessary, Ambac maintains the same percentage of the credit 
spread (over LIBOR) demanded in the market for the reference obligation as existed at the inception of the CDS. Therefore, absent changes 
in expected loss on the reference obligations or financial guarantee CDS market pricing, the financial guarantee CDS fee used for a particular 
contract in Ambac’s fair value calculations represent a consistent percentage, period to period, of the credit spread determinable from the 
reference obligation value at the balance sheet date. This results in a CDS fair value balance that fluctuates in proportion with the reference 
obligation value. 

The amount of expected loss on a reference obligation is a function of the probability that the obligation will default and severity of loss in 
the event of default. Ambac’s CDS transactions were all originally underwritten with extremely low expected losses. Both the reference 
obligation spreads and Ambac’s CDS fees at the inception of these transactions reflected these low expected losses. When reference obligations 
experience credit deterioration, there is an increase in the probability of default on the obligation and, therefore, an increase in expected loss. 
Ambac reflects the effects of changes in expected loss on the fair value of its CDS contracts by increasing the percentage of the reference

obligation spread (over LIBOR) which would be captured as a CDS fee (“relative change ratio”) at the valuation date, resulting in a higher 
mark-to-market loss on our CDS relative to any price decline on the reference obligation. The fundamental assumption is that financial guarantee 
CDS fees will increase relative to reference obligation spreads as the underlying credit quality of the reference obligation deteriorates and 
approaches payment default. For example, if the credit spread of an underlying reference obligation was 80 basis points at the inception of a 
transaction and Ambac received a 20 basis point fee for issuing a CDS on that obligation, the relative change ratio, which represents the CDS 
fee to cash market spread Ambac would utilize in its valuation calculation, would be 25%. If the reference obligation spread increased to 100 
basis points in the current reporting period, absent any observable changes in financial guarantee CDS market pricing or credit deterioration, 
Ambac’s current period CDS fee would be computed by multiplying the current reference obligation spread of 100 basis points by the relative 
change ratio of 25%, resulting in a 25 basis point fee. Thus, the model indicates we would need to receive an additional 5 basis points (25 
basis points currently less the 20 basis points contractually received) for issuing a CDS in the current reporting period for this reference 
obligation. We would then discount the product of the notional amount of the CDS and the 5 basis point hypothetical CDS fee increase, over 
the weighted average life of the reference obligation to compute the current period mark-to-market loss. Using the same example, if the 
reference obligation spread increased to 100 basis points and there was credit deterioration as evidenced by an internal rating downgrade which 
increased the relative change ratio from 25% to 35%, we would estimate a 15 basis point CDS fee increase in our model (35% of 100 basis 
points reference obligation spread, or 35 basis points currently, less the 20 basis points contractually received). Therefore, we would record a 
higher mark-to-market loss based on the computations described above absent any observable changes in financial guarantee CDS market 
pricing.

We do not adjust the relative change ratio until an actual internal rating downgrade has occurred unless we observe new pricing on financial 
guarantee CDS contracts. Since we have active surveillance procedures in place for our entire CDS portfolio, particularly for transactions at 
or near a below investment grade threshold, we believe it is unlikely that an internal downgrade would lag the actual credit deterioration of a 
transaction for any meaningful time period. The factors used to increase the relative change ratio are based on rating agency probability of 
default percentages determined by management to be appropriate for the relevant bond type. That is, the probability of default associated with 
the respective tenor and internal rating of each CDS transaction is utilized in the computation of the relative change ratio in our CDS valuation 
model. The new relative change ratio in the event of an internal downgrade of the reference obligation is calculated as the weighted average 
of: (i) a given transaction’s inception relative change ratio and (ii) a ratio of 100%. The weight given to the inception relative change ratio is 
100% minus the current probability of default (the probability of non-default) and the weight given to using a 100% relative change ratio is 
the probability of default. For example, assume a transaction having an inception relative change ratio of 33% is downgraded to B-during the 
period, at which time it has an estimated remaining life of 8 years. If the estimated probability of default for an 8 year, B-rated credit of this 
type is 60% then the revised relative change ratio will be 73.2%. The revised relative change ratio can be calculated as 33% x (100%-60%) 
+100% x 60% = 73.2%.

As noted above, reference obligation spreads incorporate market perceptions of default probability and loss severity, as well as liquidity risk 
and other factors.  By increasing the relative change ratio in our calculations proportionally to default probabilities, Ambac incorporates into 
its CDS fair value the higher expected loss on the reference obligation (probability of default x loss severity), by increasing the portion of 
reference obligation spread that should be paid to the CDS provider.

Ambac incorporates its own credit risk into the valuation of its CDS liabilities by applying a CVA to the calculations described above. Under 
our methodology, determination of the CDS fair value requires estimating hypothetical financial guarantee CDS fees for a given credit at the 
valuation date and estimating the present value of those fees. Our approach begins with pricing in the risk of default of the reference obligation 
using that obligation’s credit spread. The widening of the reference obligation spread results in a mark-to-market loss to Ambac, as the credit 
protection seller, and a gain to the credit protection buyer because the current cost of credit protection on the reference obligation (ignoring 
CDS counterparty credit risk) will be greater than the amount of the actual contractual CDS fees. The Ambac CVA represents the difference 
between the present value of the hypothetical fees discounted at LIBOR compared to rates that incorporate Ambac credit risk. The discount 
rates used to determine the Ambac CVA are estimated using relevant data points, including quoted prices of securities guaranteed by Ambac 
Assurance which indicate the value placed by market participants on Ambac Assurance’s insurance obligations and the fair value of Ambac 
Assurance surplus notes. The resulting Ambac CVA, as a percentage of the CDS mark-to-market liability determined by discounting at LIBOR, 
was 11.1% and 22.7% as of December 31, 2016 and 2015, respectively. In instances where narrower reference obligation spreads result in a 
CDS asset to Ambac, those hypothetical future CDS fees are discounted at a rate which incorporates our counterparty’s credit spread (i.e. the 
discount rate used is LIBOR plus the current credit spread of the counterparty).

In addition, when there are sufficient numbers of new observable transactions, negotiated settlements or other market indications of a general 
change in market pricing trends for CDS on a given bond type, management will adjust its assumptions about the percentage of reference 
obligation spreads captured as CDS fees to match the current market. No such adjustments were made during the periods presented. Ambac 
is not transacting CDS business currently and other guarantors have stated they have exited this product. Additionally, there have been no 
negotiated settlements of CDS contracts during the periods presented.

Key variables which impact the “Realized gains and losses and other settlements” component of “Net change in fair value of credit derivatives” 
in the Consolidated Statements of Total Comprehensive Income are the most readily observable variables since they are based solely on the 
CDS contractual terms and cash settlements. Those variables include premiums received and accrued and losses paid and payable on written 
credit derivative contracts for the appropriate accounting period. Losses paid and payable reported in “Realized gains and losses and other

settlements” include those arising after a credit event that requires a payment under the contract terms has occurred or in connection with a 
negotiated termination of a contract. The remaining key variables described above impact the “Unrealized gains (losses)” component of “Net 
change in fair value of credit derivatives.”

The net notional outstanding of Ambac’s CDS contracts were $737,380 and $970,883 at December 31, 2016 and 2015, respectively.  Credit 
derivative liabilities at December 31, 2016 and 2015 had a combined fair value of $15,349 and $34,543, respectively, and related to underlying 
reference obligations that are classified as either collateralized loan obligations (“CLOs”) or Other. Information about the above described 
model inputs used to determine the fair value of each class of credit derivatives, including the CVA as a percentage of the gross mark-to-
market liability before considering Ambac credit risk (“CVA percentage”), as of December 31, 2016 and 2015 is summarized below:

(1)  Excludes contracts for which fair values are based on credit derivative quotes rather than reference obligation quotes. As of December 31, 2015, these 
contracts had a combined notional outstanding of $58,482, WAL of 0.2 years and liability fair value of $9. Other inputs to the valuation of these transactions 
at December 31, 2015 include weighted average quotes of less than 1% of notional, weighted average rating of A+ and Ambac CVA percentage of  0.09%.

Significant unobservable inputs for credit derivatives include WAL, internal credit rating, relative change ratio and CVA percentage. A longer 
(shorter) WAL, lower (higher) reference obligation credit rating, higher (lower) relative change ratio or lower (higher) CVA, in isolation, 
would result in an increase (decrease) in the fair value liability measurement. A change in an internal credit rating of a reference obligation in 
our model will generally result in a directionally opposite change in the relative change ratio. Also, a shorter (longer) WAL will generally 
correspond with a lower (higher) CVA percentage.

Financial Guarantees:

Fair value of net financial guarantees written represents our estimate of the cost to Ambac to completely transfer its insurance obligation to 
another market participant of comparable credit worthiness. In theory, this amount should be the same amount that another market participant 
of comparable credit worthiness would hypothetically charge in the market place, on a present value basis, to provide the same protection as 
of the balance sheet date. This fair value estimate of financial guarantees is presented on a net basis and includes direct and assumed contracts 
written, net of ceded reinsurance contracts.

The fair value estimate of financial guarantees is computed by utilizing cash flows calculated at the policy level. For direct and assumed 
contracts, net cash flows for each policy included: (i) installment premium receipts, (ii) estimated future gross claim payments, (iii) subrogation 
receipts, and (iv) unpaid claims on claims presented and not yet paid for policies allocated to the Segregated Account, including Deferred 
Amounts and interest thereon.  The timing of future claim payments of the Segregated Account are at the sole discretion of the Rehabilitator.  
For ceded reinsurance contracts, net cash flows for each policy included: (i) installment ceded premium payments, (ii) ceding commission 
receipts, (iii) ceded claim receipts, and (iv) ceded subrogation payments. For each direct, assumed, and ceded reinsurance contract, the respective 
undiscounted cash flow components are aggregated to determine if we are in a net asset or net liability position. U.S. GAAP requires that the 
nonperformance risk of a financial liability be included in the estimation of fair value, which includes considering Ambac Assurance’s own 
credit risk. Accordingly, for each contract in a net liability position, we estimate the fair value using internally developed discount rates and 
market pricing that incorporate Ambac’s own credit risk and subsequently apply a profit margin. This profit margin represents what another 
market participant would require to assume the financial guarantee contracts. Given the unique nature of financial guarantees there is a lack 
of observable market information to make this estimate. A profit margin was developed based on discussions with the third-party institutions 
with valuation expertise, discussions with industry participants and yields on Ambac Assurance surplus notes. The profit margin is applied to 
the present value of contracts in a net liability position. The discount rates used for contracts in a net liability position are derived from 
guaranteed securities with future cash flows that are highly dependent upon Ambac financial guarantee payments as well as the rates implicit 
in the fair value of Ambac Assurance's surplus notes, as applicable.  For each contract in a net asset position, we estimate the fair value using 
a discount rate that is commensurate with a hypothetical buyer’s cost of capital.

This methodology is based on management’s expectations of how a market participant would estimate net cash flows. We are aware of a 
number of factors that may cause such fair or exit value to differ, perhaps materially. For example, (i) since no financial guarantor with Ambac’s 
credit quality is writing new financial guarantee business we do not have access to observable pricing data points; (ii) although the fair value 
accounting guidance for liabilities requires a company to consider the cost to completely transfer its obligation to another party of comparable 
credit worthiness, our primary insurance obligation is irrevocable and thus there is no established active market for transferring such obligations;

and (iii)  certain segments of Ambac's financial guarantees have been allocated to the Segregated Account and timing of the payments of such 
liabilities are at the sole discretion of the Rehabilitator. 

Long-term Debt:

The fair values of surplus notes issued by Ambac Assurance and the Segregated Account and classified as long-term debt is based on market 
prices received from dealer quotes or alternative pricing sources with reasonable levels of price transparency, when available.  The fair values 
of surplus notes for which quotes are not available or cannot be reasonably corroborated are internally estimated considering market transactions 
when available and internally developed discounted cash flow models.  Notes outstanding to third parties arising from Ambac Assurance's 
secured borrowing transaction are classified as long-term debt and valued using market prices received from dealer quotes.  

Other Financial Assets and Liabilities:

The fair values of Ambac’s equity interest in Ambac sponsored special purpose entities (included in Other assets), Loans, and Obligations 
under investment agreements are estimated based upon internal valuation models that discount expected cash flows using discount rates 
consistent with the credit quality of the obligor after considering collateralization.

Variable Interest Entity Assets and Liabilities:

The financial assets and liabilities of VIEs consolidated under the Consolidation Topic of the ASC consist primarily of fixed income securities, 
loans, derivative and debt instruments and are generally carried at fair value. These consolidated VIEs are securitization entities which have 
liabilities and/or assets guaranteed by Ambac Assurance. The fair values of VIE debt instruments are determined using the same methodologies 
used to value Ambac’s fixed income securities in its investment portfolio as described above. VIE debt fair value is based on market prices 
received from dealer quotes or alternative pricing sources with reasonable levels of price transparency. Such quotes are considered Level 2 
and generally consider a variety of factors, including recent trades of the same and similar securities. For those VIE debt instruments where 
quotes were not available, the debt instrument fair values are considered Level 3 and are based on internal discounted cash flow models. 
Comparable to the sensitivities of investments in fixed income securities described above, longer (shorter) expected maturities or higher (lower) 
yields used in the valuation model will, in isolation, result in decreases (increases) in fair value liability measurement for VIE debt. VIE debt 
instruments considered Level 3 include fixed rate, floating rate and zero coupon notes secured by various asset types, primarily European 
ABS. Information about the valuation inputs for the various VIE debt categories classified as Level 3 is as follows:

European ABS transactions: The fair value of such obligations classified as Level 3 was $2,551,278 and $3,016,966 at December 31, 2016 
and 2015, respectively. Fair values were calculated by using a discounted cash flow approach. The discount rates used were based on the rates 
implied from the third party quoted values for comparable notes from the same securitization entity. Significant inputs for the valuation at 
December 31, 2016 and 2015 include the following weighted averages:

December 31, 2016

a.  Coupon rate: 0.46%

b.  Maturity:

16.16 years

c.  Yield:

4.95%

December 31, 2015

a.  Coupon rate: 1.38%

b.  Maturity:

16.44 years

c.  Yield:

6.08%

US Commercial ABS transaction: The fair value of such obligations classified as Level 3 was $30,942 and $163,204 at December 31, 2016 
and 2015, respectively. Fair values were calculated as the sum of the present value of expected future cash flows from the underlying VIE 
assets plus the present value of the related Ambac financial guarantee cash flows.  The discount rates applied to cash flows sourced from VIE 
assets were based on interest rates for similar obligations. The fair value of financial guarantee cash flows include internal estimates of future 
loss payments by Ambac discounted at a rate that incorporates Ambac’s own credit risk. Significant inputs for the valuation at December 31, 
2016 and 2015, include the following weighted averages:

December 31, 2016

a.  Coupon rate: 5.88%

b.  Maturity:

20.85 years

c.  Yield:

5.86%

VIE derivative asset and liability fair values are determined using valuation models. When specific derivative contractual terms are available 
and may be valued primarily by reference to interest rates, foreign exchange rates and yield curves that are observable and regularly quoted, 
the derivatives are valued using vendor-developed models. Other derivatives within the VIEs that include significant unobservable valuation 
inputs are valued using internally developed models. VIE derivative fair value balances at December 31, 2016 and 2015 were developed using 
vendor-developed models and do not use significant unobservable inputs.

(Dollar Amounts in Thousands, Except Share Amounts)

The fair value of VIE assets are obtained from market quotes when available. Typically the asset fair values are not readily available from 
market quotes and are estimated internally. The consolidated VIEs are securitization entities in which net cash flows from assets and derivatives 
(after adjusting for financial guarantor cash flows and other expenses) will be paid out to note holders or equity interests. Our valuation of 
VIE assets (fixed income securities or loans), therefore, are generally derived from the fair value of notes and derivatives, as described above, 
adjusted for the fair value of cash flows from Ambac’s financial guarantee. The fair value of financial guarantee cash flows include: (i) estimated 
future premiums discounted at a rate consistent with that implicit in the fair value of the VIE’s liabilities and (ii) internal estimates of future 
loss payments by Ambac discounted at a rate that includes Ambac’s own credit risk. Estimated future premium payments to be paid by the 
VIEs were discounted at a weighted average rate of 3.6% and 4.4% at December 31, 2016 and 2015, respectively. The value of future loss 
payments to be paid by Ambac to the VIEs was adjusted to include an Ambac CVA appropriate for the term of expected Ambac claim payments.

Additional Fair Value Information:

The following tables present the changes in the Level 3 fair value category for the periods presented in 2016 and 2015. Ambac classifies 
financial instruments in Level 3 of the fair value hierarchy when there is reliance on at least one significant unobservable input to the valuation 
model. In addition to these unobservable inputs, the valuation models for Level 3 financial instruments typically also rely on a number of 
inputs that are readily observable either directly or indirectly. Thus, the gains and losses presented below include changes in the fair value 
related to both observable and unobservable inputs.

Invested assets and VIE long-term debt are transferred into Level 3 when internal valuation models that include significant unobservable inputs 
are used to estimate fair value. All such securities that have internally modeled fair values have been classified as Level 3.  Other Asset-backed 
securities transferred into Level 3 in 2016 consist of a subordinated tranche of a resecuritization collateralized by Ambac-insured military 
housing bonds.  Non-agency RMBS transferred into Level 3 in 2014 and 2016 consist of certain investments in Ambac-wrapped RMBS 
securities for which projected cash flows consist solely of Deferred Amounts and interest thereon.   These invested assets were internally 
valued as management could not corroborate the reasonableness of third party quotes. Derivative instruments are transferred into Level 3 
when the use of unobservable inputs becomes significant to the overall valuation. Derivative instruments transferred into Level 3 in 2015 
consisted of certain interest rate swap assets with counterparty credit adjustments. All transfers into and out of Level 3 represent transfers 
between Level 3 and Level 2. There were no transfers between Level 1 and Level 2 for the periods presented. All transfers between fair value 
hierarchy Levels 1, 2, and 3 are recognized at the beginning of each accounting period.

Gains and losses (realized and unrealized) relating to Level 3 assets and liabilities included in earnings for the affected periods are reported 
as follows:

Management has determined that the unrealized losses reflected in the tables above are temporary in nature as of December 31, 2016 and 2015
based upon (i) no unexpected principal and interest payment defaults on these securities; (ii) analysis of the creditworthiness of the issuer and 
financial guarantor, as applicable, and analysis of projected defaults on the underlying collateral; (iii) management has no intent to sell these 
investments in debt securities; and (iv) it is not more likely than not that Ambac will be required to sell these debt securities before the anticipated 
recovery of its amortized cost basis. The assessment under (iv) is based on a comparison of future available liquidity from the investment 
portfolio against the projected net cash flow from operating activities and debt service. For purposes of this assessment, available liquidity 
from the investment portfolio is comprised of the fair value of securities for which management has asserted its intent to sell, trading securities 
plus the projected principal and interest payments from the remaining securities in the portfolio. To the extent that securities that management 
intends to sell are in an unrealized loss position, they would have already been considered other-than-temporarily impaired with the amortized 
cost written down to fair value.  For purposes of this analysis, residual cash flows are projected to be invested at current reinvestment rates 
consistent with existing fixed income portfolio holdings.  Because the above-described assessment indicates that future available liquidity 
exceeds projected net cash outflow, it is not more likely than not that we would be required to sell securities in an unrealized loss position 
before the recovery of their amortized cost basis. In the liquidity assessment described above, principal payments on securities pledged as 
collateral are not considered to be available for other liquidity needs until the collateralized positions are projected to be settled. Projected 
interest receipts on securities pledged as collateral generally belong to Ambac and are considered to be sources of available liquidity from the 
investment portfolio. 

As of December 31, 2016, for securities that have indications of possible other-than-temporary impairment but which management does not 
intend to sell and will not more likely than not be required to sell, management compared the present value of cash flows expected to be 
collected to the amortized cost basis of the securities to assess whether the amortized cost will be recovered. Cash flows were discounted at 
the effective interest rate implicit in the security at the date of acquisition (or Fresh Start Reporting Date of April 30, 2013 for securities 
purchased prior to that date) or for debt securities that are beneficial interests in securitized financial assets, at a rate equal to the current yield 
used to accrete the beneficial interest. For floating rate securities, future cash flows and the discount rate used were both adjusted to reflect 
changes in the index rate applicable to each security as of the evaluation date. Of the securities that were in a gross unrealized loss position 
at December 31, 2016, $890,952 of the total fair value and $53,273 of the unrealized loss related to below investment grade securities and 
non-rated securities. Of the securities that were in a gross unrealized loss position at December 31, 2015, $953,000 of the total fair value and 
$69,214 of the unrealized loss related to below investment grade securities and non-rated securities. With respect to all Ambac insured securities 
owned, future cash flows used to measure credit impairment represents the sum of (i) the bond’s intrinsic cash flows and (ii) the estimated 
Ambac Assurance claim payments. For Ambac-insured securities owned guaranteed under policies allocated to the Segregated Account, the 
estimate of Ambac Assurance claim payments includes interest on Deferred Amounts. Ambac estimates the timing of claim payment receipts

orders from the Rehabilitation Court or actions by the Rehabilitator with respect to the form, amount and timing of satisfying permitted policy 
claims, or making payments on Deferred Amounts or surplus notes, may have a material effect on the fair value of Ambac insured securities 
and future recognition of other-than-temporary impairments.  Refer to Note 1. Background and Business Description for information relating 
to the amended Segregated Account Rehabilitation Plan. Ambac’s assessment about whether a decline in value is other-than-temporary reflects 
management’s current judgment regarding facts and circumstances specific to a security and the factors noted above, including Ambac's 
intention to sell securities and ability to hold temporarily impaired securities until recovery. If that judgment changes, Ambac may ultimately 
record a charge for other-than-temporary impairment in future periods.

Municipal and corporate obligations

The gross unrealized losses on municipal and corporate obligations as of December 31, 2016 are primarily the result of the increase in interest 
rates since purchase (or the Fresh Start Reporting Date of April 30, 2013 if owned as of that date). These securities are primarily fixed-rate 
securities with an investment grade credit rating. Management believes that the timely receipt of all principal and interest on these positions 
is probable.

Residential mortgage-backed securities

Of  the  $43,785  of  unrealized  losses  on  residential  mortgage-backed  securities,  $43,380  is  attributable  to Ambac  insured  securities. The 
unrealized loss on these securities is primarily the result of discount accretion, which has exceeded the increase in fair value. As part of the 
quarterly impairment review process, management estimates expected future cash flows from residential mortgage-backed securities. This 
approach includes the utilization of market accepted software models in conjunction with detailed data of the historical performance of the 
collateral pools, which assists in the determination of assumptions such as defaults, severity and voluntary prepayment rates that are largely 
driven by home price forecasts as well as other macro-economic factors.  Additionally, for Ambac insured securities that are allocated to the 
Segregated Account, expected future cash flows include assumptions about the timing of Ambac Assurance claim payments, including interest 
on Deferred Amounts, although the actual timing of such payments are at the sole discretion of the Rehabilitator.  These assumptions are used 
to project future cash flows for each security. Management considered this analysis in making our determination that a credit loss has not 
occurred at December 31, 2016 on these transactions.

(1)  Other-than-temporary impairments exclude impairment amounts recorded in other comprehensive income under ASC Paragraph 320-10-65-1, which 
comprise non-credit related amounts on securities that are credit impaired but which management does not intend to sell and it is not more likely than not 
that the company will be required to sell before recovery of the amortized cost basis.

Since commencement of the Segregated Account Rehabilitation Proceedings, changes in the estimated timing of claim payments have resulted 
in adverse changes in projected cash flows on certain impaired Ambac insured securities. Such changes in estimated claim payments on Ambac 
insured securities contributed to net other-than-temporary impairments for the periods presented in the table above. Further changes to the 
timing of estimated claim payments could result in additional other-than-temporary impairment charges in the future. Ambac’s other-than-
temporary impairments also relate to the company’s intent to sell certain securities that were in an unrealized loss position as of the impairment 
evaluation dates.  Future changes in our estimated liquidity needs could result in a determination that Ambac no longer has the ability to hold 
additional securities that are in an unrealized loss position, which could result in additional other-than-temporary impairment charges.

Counterparty Collateral, Deposits with Regulators and Other Restrictions:

Ambac routinely pledges and receives collateral related to certain business lines and/or transactions. Ambac pledges assets it holds in its 
investment portfolio to investment agreement and derivative counterparties. Securities pledged to investment agreement counterparties may 
not then be re-pledged to another entity. Ambac’s counterparties under derivative agreements have the right to pledge or rehypothecate the 
securities and as such, these pledged securities are separately classified on the Consolidated Balance Sheets as “Fixed income securities pledged 
as collateral, at fair value”.

The following table presents (i) the sources of collateral either received from various counterparties where Ambac is permitted to sell or re-
pledge the collateral or collateral held directly in the investment portfolio and (ii) how that collateral was pledged to various investment 
agreement, derivative and repurchase agreement counterparties at December 31, 2016 and 2015:

Securities with fair value of $360,759 and $396,100 at December 31, 2016 and 2015, respectively, were held by a bankruptcy remote trust to 
collateralize and fund repayment of debt issued through a secured borrowing transaction. The securities may not be sold or repledged by the 
trust. These assets are held and the secured debt issued by entities that qualified as VIEs and were consolidated in Ambac’s consolidated

Guaranteed Securities:

Ambac’s fixed income portfolio includes securities covered by guarantees issued by Ambac Assurance and other financial guarantors (“insured 
securities”). The published rating agency ratings on these securities reflect the higher of the financial strength rating of the financial guarantor 
or the rating of the underlying issuer. Rating agencies do not always publish separate underlying ratings (those ratings excluding the insurance 
by the financial guarantor) because the insurance cannot be legally separated from the underlying security by the insurer. In the event these 
underlying ratings are not available from the rating agencies, Ambac will assign an internal rating. The following table represents the fair 
value, including the value of the financial guarantee, and weighted-average underlying rating, excluding the financial guarantee, of the insured 
securities at December 31, 2016 and 2015, respectively:

Financial Guarantee Credit Derivatives:

Credit derivatives, which are privately negotiated contracts, provide the counterparty with credit protection against the occurrence of a specific 
event such as a payment default or bankruptcy relating to an underlying obligation. Upon a credit event, Ambac is required to make payments 
equal to the difference between the scheduled debt service payment and the actual payment made by the issuer. Substantially all of Ambac’s 
credit derivative contracts relate to structured finance transactions. Credit derivatives issued are insured by Ambac Assurance. None of the 
outstanding credit derivative transactions at December 31, 2016 include ratings based collateral-posting triggers or otherwise require Ambac 
to post collateral regardless of Ambac’s ratings or the size of the mark to market exposure to Ambac.

The portfolio of our credit derivatives were written on a “pay-as-you-go” basis. Similar to an insurance policy execution, pay-as-you-go 
provides that Ambac pays interest shortfalls on the referenced transaction as they are incurred on each scheduled payment date, but only pays 
principal shortfalls upon the earlier of (i) the date on which the assets designated to fund the referenced obligation have been disposed of and 
(ii) the legal final maturity date of the referenced obligation.

Ambac maintains internal credit ratings on its guaranteed obligations, including credit derivative contracts, solely to indicate management’s 
view of the underlying credit quality of the guaranteed obligations. Independent rating agencies may have assigned different ratings on the 
credits in Ambac’s portfolio than Ambac’s internal ratings. The following tables summarize the gross principal notional outstanding for CDS 
contracts, by Ambac rating, for each major category as of December 31, 2016 and 2015:

(1) BBB internal ratings reflect bonds which are of medium grade credit quality with adequate capacity to pay interest and repay principal. Certain protective
elements and margins may weaken under adverse economic conditions and changing circumstances. These bonds are more likely than higher rated bonds 
to exhibit unreliable protection levels over all cycles.

(2) Below investment grade internal ratings reflect bonds which are of speculative grade credit quality with the adequacy of future margin levels for payment 

of interest and repayment of principal potentially adversely affected by major ongoing uncertainties or exposure to adverse conditions.

The  maximum  potential  amount  of  future  payments  under Ambac’s  credit  derivative  contracts  is  generally  the  gross  principal  notional 
outstanding amount included in the above table plus future interest payments payable by the derivative reference obligations. Since Ambac’s 
credit derivatives typically reference obligations of or assets held by special purpose entities that meet the definition of a VIE, the amount of 
maximum potential future payments for credit derivatives is included in the table in Note 3. Special Purpose Entities, Including Variable 
Interest Entities.

Changes in fair value of Ambac’s credit derivative contracts are accounted for at fair value since they do not qualify for the financial guarantee 
scope exception under the Derivatives and Hedging Topic of the ASC. Changes in fair value are recorded in “Net change in fair value of credit 
derivatives” on the Consolidated Statements of Total Comprehensive Income. Although CDS contracts are accounted for at fair value, they 
are surveilled similar to non-derivative financial guarantee contracts. As with financial guarantee insurance policies, Ambac’s Portfolio Risk 
Management group tracks credit migration of CDS contracts’ reference obligations from period to period.

Adversely classified credits are assigned risk classifications by the Portfolio Risk Management group. As of December 31, 2016, there are 
two credit derivative contracts on Ambac’s adversely classified credit listing, with a net derivative liability fair value of $6,123 and gross 
notional principal outstanding of $67,783. As of December 31, 2015, there were two CDS contracts on Ambac’s adversely classified credit 
listing, with a net derivative liability fair value of $19,820 and total notional principal outstanding of $68,526.

Financial Services Derivative Products:

Ambac, through its subsidiary Ambac Financial Services (“AFS”), provides interest rate swaps to states, municipalities and their authorities, 
asset-backed issuers and other entities in connection with their financings. AFS manages its interest rate swaps business with the goal of 
retaining some basis risk and excess interest rate sensitivity as an economic hedge against the effects of rising interest rates elsewhere in the 
Company, including on Ambac’s financial guarantee exposures. As of December 31, 2016 and 2015 the notional amounts of AFS’s trading 
derivative products are as follows:

Contingent Features in Derivatives Related to Ambac Credit Risk

Ambac’s over-the-counter interest rate swaps are centrally cleared when eligible. Certain interest rate swaps remain with professional swap-
dealer counterparties and certain front-end counterparties. These non-cleared swaps are generally executed under standardized derivative 
documents including collateral support and master netting agreements. Under these agreements, Ambac is required to post collateral in the

AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES

(Dollar Amounts in Thousands, Except Share Amounts)

event  net  unrealized  losses  exceed  predetermined  threshold  levels. Additionally,  given  that Ambac Assurance  is  no  longer  rated  by  an 
independent rating agency, counterparties have the right to terminate the swap positions.

As of December 31, 2016 and 2015, the net liability fair value of all derivative instruments with contingent features linked to Ambac’s own 
credit risk was $82,944 and $95,415, respectively, related to which Ambac had posted cash and securities as collateral with a fair value of 
$128,754 and $147,974, respectively. All such ratings-based contingent features have been triggered as requiring maximum collateral levels 
to be posted by Ambac while preserving counterparties’ rights to terminate the contracts. Assuming all contracts terminated on December 31, 
2016,  settlement  of  collateral  balances  and  net  derivative  liabilities  would  result  in  a  net  receipt  of  cash  and/or  securities  by Ambac.  If 
counterparties elect to exercise their right to terminate, the actual termination payment amounts will be determined in accordance with derivative 
contract terms, which may result in amounts that differ from values as reported in Ambac’s financial statements.

12.        LOANS 

Loans had been extended: (i) by VIEs which are consolidated by Ambac under ASC Topic 810 as a result of Ambac’s financial guarantees of 
the VIEs’ note liabilities and/or assets and (ii) to certain institutions in connection with various transactions. 

Loans by consolidated VIEs are generally carried at fair value on the Consolidated Balance Sheets. See Note 3. Special Purpose Entities, 
Including Variable Interest Entities for further information about VIEs for which the assets and liabilities are carried at fair value. 

Other loans had an outstanding principal balance of $4,873 and $6,205 at December 31, 2016 and 2015, respectively. Interest rates on these 
loans were 4.53% and 4.75% at December 31, 2016 and 2015, respectively. The maturity date of these loans were June 2026 as of December 
31, 2016 and 2015. Collectability of these loans is evaluated on an ongoing basis; no loan has been considered impaired and as such no loan 
impairments have been recorded as of December 31, 2016 and 2015.

Ambac Assurance surplus notes, with a par amount of $862,945 and $881,496 at December 31, 2016 and 2015, respectively, are reported in 
long-term debt on the Consolidated Balance Sheet and have a scheduled maturity of June 7, 2020. In 2016 and 2015, Ambac repurchased 
$18,551 and  $11,804 par amount of these surplus notes, respectively. The gains (losses) on these repurchases were  $1,677 and $(1,246), and 
recognized in Net realized gains (losses) on extinguishment of debt of the Consolidated Statements of Total Comprehensive Income for the 
years ended December 31, 2016 and 2015, respectively.  These surplus notes were issued in connection with the Settlement Agreement and 
were recorded at their fair value at the date of issuance. The discount on these notes is currently being accreted into income using the effective 
interest method at an imputed interest rate of of 10.5%. All payments of principal and interest on the Ambac Assurance surplus notes are 
subject to the prior approval of the OCI. If the OCI does not approve the payment of interest on the Ambac Assurance surplus notes, such 
interest will accrue and compound annually until paid. OCI disapproved the requests of Ambac Assurance to pay interest on the outstanding 
Ambac Assurance surplus notes on their respective scheduled interest payment dates since their issuance.  

Surplus Notes, Segregated Account

The Segregated Account surplus notes, with a par amount of $39,102 and $39,102 at December 31, 2016 and 2015, respectively, are reported 
in long-term debt on the Consolidated Balance Sheets and have a scheduled maturity of June 7, 2020. These surplus notes were recorded at 
their fair value at the date of issuance. The discount on these notes is currently being accreted into income using the effective interest method 
at an imputed interest rate of 10.5%. All payments of principal and interest on the Segregated Account surplus notes are subject to the prior 
approval of the OCI. If the OCI does not approve the payment of interest on the Segregated Account surplus notes, such interest will accrue 
and compound annually until paid. OCI disapproved of the requests of the Rehabilitator of the Segregated Account, acting for and on behalf 
of the Segregated Account, to pay interest on the outstanding Segregated Account surplus notes on their respective scheduled interest payment 
dates since their issuance.

(Dollar Amounts in Thousands, Except Share Amounts)

As described in Note 1. Background and Business Description, the Rehabilitator redeemed certain Segregated Account surplus notes (other 
than junior surplus notes) on November 20, 2014 at a redemption price that included an amount equal to principal plus accrued interest on 
such redeemed surplus notes.  Such redemption also triggered similar proportionate redemption payments on Ambac Assurance surplus notes. 
The redemption of surplus notes resulted in a charge representing the accelerated recognition of the unamortized discount on the redeemed 
surplus notes. The unamortized discount on the redeemed portion of Segregated Account and General Account surplus notes was $3,134 and 
$71,590,  respectively,  and  recognized  in  Net  realized  gains  (losses)  on  extinguishment  of  debt  of  the  Consolidated  Statements  of  Total 
Comprehensive Income for the year ended December 31, 2014.

Junior Surplus Notes, Segregated Account

The Segregated Account junior surplus notes, with a par value of $374,036 and $378,039 at December 31, 2016 and 2015, respectively, are 
reported  in  long-term  debt  on  the  Consolidated  Balance  Sheets  and  have  a  scheduled  maturity  of  June 7,  2020,  subject  to  the  following 
restrictions.  Principal and interest payments on these junior surplus notes cannot be made until all Ambac Assurance (General Account) and 
Segregated Account surplus notes are paid in full and after all Segregated Account future and existing senior indebtedness, policy and other 
priority claims have been paid in full. All payments of principal and interest on the junior surplus notes are subject to the prior approval of 
the OCI. If the OCI does not approve the payment of interest on the junior surplus notes, such interest will accrue and compound annually 
until paid. No such approval has been sought or obtained to pay interest on junior surplus notes since their issuance. 

• 

• 

Par value at December 31, 2016 and 2015 includes $24,037 and $28,039, respectively, of junior surplus notes issued in connection 
with a settlement agreement (the “OSS Settlement Agreement”) entered into among Ambac, Ambac Assurance, the Segregated Account 
and One State Street, LLC (“OSS”) with respect to the termination of Ambac’s office lease with OSS. Part of these junior surplus notes 
($13,056 par value) will be reduced periodically as rent payments are made by Ambac Assurance beginning in January 2016. Par value 
of these junior surplus notes have been reduced by $4,002 during 2016 as rent payments were made by Ambac Assurance. These junior 
surplus notes were recorded at their fair value at the dates of issuance. The discount on these notes are currently being accreted into 
income using the effective interest method at an imputed interest rate of 19.5%.  

Par value at December 31, 2016 and 2015 includes $350,000 face amount of a junior surplus note originally issued to Ambac pursuant 
to Ambac's Reorganization Plan in accordance with the Mediation Agreement and that Ambac sold to a Trust on August 28, 2014.       
This junior surplus note was recorded at a discount to par based on its fair value on August 28, 2014. Ambac is accreting the discount 
on this junior surplus note into earnings using the effective interest method, based on an imputed interest rate of 8.4%. 

Secured Borrowing

The secured borrowing, with a par value of $102,986 and $132,467 at December 31, 2016 and 2015, respectively, is reported in long-term 
debt on the Consolidated Balance Sheets and has a legal maturity of July 25, 2047.  Interest on the secured borrowing is payable monthly at 
an annual rate of one month LIBOR + 2.8%. Refer to Note 3. Special Purpose Entities, Including Variable Interest Entities for further discussion 
on the secured borrowing transaction. 

Variable Interest Entities, Long-term Debt

The variable interest entity notes were issued by consolidated VIEs.  Ambac is the primary beneficiary of the VIEs as a result of providing 
financial guarantees on certain of the the variable interest obligations. Consequently, Ambac has consolidated these variable interest entity 
notes and all other assets and liabilities of the VIEs. Ambac is not primarily liable for the debt obligations of these entities. Ambac would only 
be required to make payments on these debt obligations in the event that the issuer defaults on any principal or interest due and to the extent 
such obligations are guaranteed by Ambac. The total unpaid principal amount of outstanding long-term debt associated with VIEs consolidated 
as a result of the financial guarantee provided by Ambac was $8,854,530 and $10,803,729 as of December 31, 2016 and 2015, respectively. 
The range of final maturity dates of the outstanding long-term debt associated with these VIEs is November 2018 to December 2047 as of 
December 31, 2016 and 2015.  As of December 31, 2016 and 2015, the interest rates on these VIEs’ long-term debt ranged from 0.82% to 
13.00% and from 0.96% to 13.00%, respectively.  Final maturities of VIE long-term debt for each of the five years following December 31, 
2016 are as follows: 2017-$0; 2018-$128,801; 2019-$301,375; 2020-$46,848; 2021-$107,432.

14.        OBLIGATIONS UNDER INVESTMENT AGREEMENTS 

As of December 31, 2016 and 2015, the carrying value of obligations under investment agreements, including unamortized discounts or 
premiums to principal, were $82,358 and $100,358, respectively.  As of December 31, 2016 and 2015, the contractual variable interest rates 
for these agreements, ranged from 0.94% to 0.94% and 0.43% to 0.43%, respectively. The remaining principal amount under investment 
agreements is due during the year ending December 31, 2017.

In accordance with the Income Tax Topic of the ASC, a valuation allowance is recognized if, based on the weight of available evidence, it is 
more-likely-than-not that some, or all, of the deferred tax asset will not be realized. As a result of the risks and uncertainties associated with 
future operating results, management believes it is more likely than not that the Company will not generate sufficient taxable income to recover 
the deferred tax operating asset and therefore has a full valuation allowance.

$0, $0 and $0, respectively. Ambac had approximately $0, $0 and $0, for the payment of interest accrued at December 31, 2016, 2015 and 
2014, respectively. 

NOL Usage 

Pursuant  to  the Amended TSA,  to  the  extent Ambac Assurance  generates  taxable  income  after  September 30,  2011,  which  is  offset  with 
"Allocated NOLs" of $3,650,000, it is obligated to make payments (“Tolling Payments”), subject to certain credits, to Ambac in accordance

closing agreement the United States Department of Treasury receives 12.5% of Tier C and 17.5% of Tier D Tolling Payments.

Any post determination date NOLs generated by Ambac Assurance are utilized prior to any Allocated NOLs for which Tolling Payments will 
be due.  Ambac Assurance has utilized all of its current post determination date NOLs generated from September 30, 2011 through December 31, 
2015 and December 31, 2016, generating cumulative taxable income of $877,313 and $1,086,124, respectively.  Additional post determination 
date NOLs may be generated (and utilized prior to any Allocated NOLs for which Tolling Payments will be due) in the future. Of the bankruptcy 
related credits available to offset the first $5,000 of payments due under each of the NOL usage Tiers A, B, and C, Ambac Assurance has fully 
utilized the combined $10,000 of  Tier A and Tier B credits.  For the year ended December 31, 2015, Ambac Assurance utilized all of the 
$479,000 Tier A NOL and $402,192 of the $1,057,000 Tier B NOL resulting in a Tolling Payment, net of applicable credits, of $71,454 that 
was paid to Ambac in 2016. For the year ended December 31, 2016 , Ambac Assurance's utilization of $204,932, of the $1,057,000 allocated 
Tier B NOL resulted in additional accrued Tolling Payments, net of applicable credits, of $28,691.  Tolling Payments due as a result of 2016 
taxable income will be paid to Ambac in May 2017 (subject to review by the Rehabilitator).

To the extent Ambac Assurance utilizes Allocated NOLs generated prior to September 30, 2011 greater than $3,650,000, beginning on the 
fifth anniversary date subsequent to Ambac's May 1, 2013 emergence from bankruptcy, and subject to Ambac's consent, not to be unreasonably 
withheld, Ambac Assurance may utilize Ambac's NOL in exchange for a payment to Ambac of 25% of the federal income tax liability that 
Ambac Assurance would have been paid if the NOLs were not available. 

After Ambac fully utilizes its Allocated NOLs it may utilize Ambac Assurance's then remaining Allocated NOLs in exchange for a payment 
of 50% of the federal income tax liability that Ambac would have paid had Ambac Assurance's NOL not been available.

As of December 31, 2016, the remaining balance of the $3,650,000 NOL allocated to Ambac Assurance was $2,563,876.  As of December 31, 
2016 Ambac's NOL was $1,389,359.

16.        EMPLOYMENT BENEFIT PLANS 

Postretirement Health Care and Other Benefits: 

Ambac provides postretirement and postemployment benefits, including health and life benefits for certain employees who meet certain age 
and  service  requirements.  None  of  the  plans  are  currently  funded.  In  addition, Ambac  provides  severance  benefits.    Postretirement  and 
postemployment benefits expenses, including severance benefits paid, was $8,846, $2,570 and $2,249 for the years ended December 31, 2016, 
2015 and 2014, respectively.

Effective August 1, 2005, new employees were not eligible for postretirement benefits. In 2013, postretirement benefits offered to retirees 
were amended such that Ambac would no longer sponsor a health plan beginning in 2014. This required retirees to purchase their own insurance 
policy with a portion of their premium being reimbursed by Ambac. The unfunded accumulated postretirement benefit obligation was $9,958
as of December 31, 2016. The assumed health care cost trend rates range from 5.8% in 2017, decreasing ratably to 4.5% in 2023. Increasing 
the assumed health care cost trend rate by one percentage point in each future year would increase the accumulated postretirement benefit 
obligation at December 31, 2016, by $187 and the 2016 benefit expense by $13. Decreasing the assumed health care cost trend rate by one 
percentage point in each future year would decrease the accumulated postretirement benefit obligation at December 31, 2016 by $260 and the 
2016 benefit expense by $19. 

The following table sets forth projected benefit payments from Ambac’s postretirement plan over the next ten years for current retirees:

The discount rate used in determining the projected benefit obligations for the postretirement plan is selected by reference to the year-end 
Citigroup pension liability index with similar duration to that of the benefit plans. The rate used for the projected plan benefit obligations at 
the measurement date for December 31, 2016 and 2015 was 4.00% and 4.25%, respectively. 

Savings Incentive Plan: 

Substantially all employees of Ambac Assurance are covered by a defined contribution plan (the “Savings Incentive Plan”). Ambac Assurance 
makes employer matching contributions equal 100% of the employees’ contributions, up to 3% of such participants’ compensation, as defined 
in the plan, plus 50% of contributions to an additional 2% of compensation, subject to limits set by the Internal Revenue Code. The total cost 
of the Savings Incentive Plan was $911, $1,042 and $1,056 for the years December 31, 2016, 2015 and 2014, respectively.

Incentive Compensation - Stock and Cash:

Incentive compensation is a key component of our compensation strategy. Incentive compensation payouts can be highly variable from year 
to year and are generally based on the execution of our strategies at the Company, as well as business unit and individual performance. In 
January of each year a determination is made as to the total amount of incentive compensation to be awarded.  Employees, directors and 
consultants of Ambac are eligible to participate in Ambac’s 2013 Incentive Compensation Plan (“2013 Plan”) subject to the discretion of the 
compensation committee of Ambac’s Board of Directors. The 2013 Plan provides for incentives and rewards that are valued or determined 
by reference to Ambac common stock as traded on the NASDAQ exchange. There are 4,000,000 shares of Ambac’s common stock authorized 
for awards under the 2013 Plan of which 3,004,639 shares are available for future grant as of December 31, 2016.

In March 2014, Ambac developed a long term incentive compensation plan (“LTIP”) as a sub-plan of the 2013 Plan. The LTIP, approved by 
the Compensation Committee of the Board of Directors, is a significant component of management’s compensation program that is intended 
to strike an appropriate balance between short and long-term incentives aimed at fostering retention and aligning management's interest with 
those of Ambac's stakeholders. Awards granted under the LTIP are designed to further the financial and operational objectives of both Ambac 
and Ambac Assurance. The LTIP is intended to be an annual program that allows for both cash and equity performance awards to certain US 
employees.  

In 2015, Ambac UK 's Board of Directors adopted a long term incentive plan which provides cash based performance awards to Ambac UK 
employees.  Cash based compensation expense related to performance awards granted to Ambac UK employees was $283 and $253 for the 
years ended December 31, 2016 and 2015, respectively. 

For all employees, an allocation of incentive compensation is made between annual bonuses and LTIP awards.  Beginning with the annual 
bonus for Executive Officers payable in 2017, 25% was paid in restricted stock units of Ambac with a deferred settlement provision, and the 
remainder was paid in cash. These deferred settlement restricted stock units will settle and convert into Ambac common stock annually over 
a two year period; 50% on the first anniversary of the grant date and the remaining 50% on the second anniversary of the grant date (unless 
settled earlier due to an employee’s departure from the Company (other than for cause)). 

The amount of stock-based compensation expense and corresponding after-tax expense are as follows:

Stock options were awarded to directors in 2013 (vested on April 30, 2014) and to the former Chief Executive Officer in 2015 (vested January 
1, 2016), all with an expiry term of seven years from the grant date, subject to earlier expiration upon the recipient's departure from the 
Company.  The Company intends to use Treasury shares first and then, if necessary, issue new shares to satisfy stock option exercises.  No 
stock options were awarded in 2014 or 2016.

The Black-Scholes-Merton model was used to estimate the fair value of the service condition based stock options on the grant date. The 
following assumptions were used in estimating the fair value of options awarded in 2015: 

Year Ended December 31,

Risk-free interest rate

Expected volatility

Dividend yield

Expected life

Weighted-average grant-date fair value per share

2015

1.283%

42.8%

0.0%

4.13 years

$

8.69

The expected volatility is based on implied volatilities from traded options on Ambac’s stock, the historical volatility of Ambac’s stock and 
the historical volatilities of our peer industry group. Peer group historical volatilities were considered due to the fact that Ambac stock had 
been traded for a time period less than the expected life of the options. A zero dividend yield was assumed based on the uncertainty of Ambac 
making dividend payments over the expected life of these options. The risk-free interest rate reflects the U.S. Treasury yield curve in effect 
at the time of the grant. The expected life represents the period of time that options granted are expected to be outstanding and is based on 
certain factors we believe will influence exercise behavior.

All stock options granted were fully vested as of December 31, 2016.  Total unrecognized compensation costs related to unvested stock options 
granted were $0 as of December 31, 2016.  No stock options were exercised during the years ended December 31, 2016, 2015 and 2014, 
respectively.

Restricted Stock Units (“RSUs”):

RSUs were awarded to employees in 2013 that vested in two installments, 50% on the grant date and 50% on the first anniversary of the grant 
date. These RSU awards provided for accelerated vesting upon change in control or death or disability. These employee RSUs settled and 
converted into Ambac shares upon the earlier of (a) the employee’s termination of employment (other than for cause) and (b) the second 
anniversary of the applicable vesting date. 

In 2015 and 2016, RSU awards were granted to the former Chief Executive Officer.  The 2015 award would vest in three equal installments 
on January 1, 2016, 2017 and 2018.  The 2016 award would vest in three equal installments on December 31, 2016, 2017 and 2018. The former 
Chief Executive Officer departed the Company in 2016 and pursuant to the terms set forth in his settlement agreements and the RSU award 
agreements, (i) the service requirement for the entire 2015 award was met and the entire RSU award vested in 2016 and (ii) the service 
requirement for one-third of the 2016 RSU award was met and vested in 2016 with the remaining two-thirds of the 2016 RSU award forfeited.    

In 2016, RSU awards were granted to certain Executive Officers.  The awards vest in three equal installments on February 21, 2017, 2018 and 
2019 ("Time-Based RSUs").  The vesting of the Time-Based RSUs are expressly conditioned upon the Executives continued service with 
Ambac through the applicable vesting date.

RSUs are awarded annually to directors that vest on the last day of April of the following year. These RSUs will not settle until the respective 
director’s termination from the board of directors or, if earlier, upon a change in control. All RSUs provide for accelerated vesting upon a 
change in control, death or disability or involuntary removal other than for cause (not including removal pursuant to a shareholder vote at a 
regularly scheduled annual meeting of shareholders). Upon termination (other than for cause), the RSUs shall vest as of the date of such 
termination in an amount equal to the number of then outstanding RSUs multiplied by a fraction, the numerator of which shall be the number 
of calendar days which have lapsed since the grant date and the denominator of which shall be the total number of calendar days of the original 
vesting period.

As of December 31, 2016, 264,230 RSUs remained outstanding, of which (i) 102,794 units required future service as a condition to the delivery

(1)  When restricted stock unit awards issued by Ambac become taxable compensation to employees, shares may be withheld to cover the employee’s withholding 
taxes.  For the year ended December 31, 2016, Ambac purchased 23,148 of shares from employees that settled restricted stock units to meet the required 
tax withholdings.

Ambac’s closing share price on the grant date was used to estimate the fair value of the service condition based RSU on the grant date.  The 
weighted average grant date fair value of RSUs granted during 2016, 2015 and 2014 was $14.34, $23.71 and $30.18, respectively.  As of 
December 31, 2016, there was $696 of total unrecognized compensation costs related to unvested RSUs granted. These costs are expected to 
be recognized over a weighted average period of 1.1 years. The fair value for RSUs vested and delivered during the year ended December 31, 
2016, 2015 and 2014 was $2,965, $864 and $37, respectively.

Performance Stock Awards ("PSUs"):

Performance awards were granted under the LTIP to certain employees ("LTIP Awards").  These grants vest in 3 years and are evenly split 
between PSUs and cash. Actual awards will be based on performance at both Ambac and Ambac Assurance.  Actual awards can payout 0% 
to 200% of the number of units granted.  Ambac performance will be evaluated relative to cumulative earnings before interest, taxes, depreciation 
and amortization over the vesting period (exclusive of Ambac Assurance and its subsidiaries' earnings), which is intended to reward participants 
on  generating  taxable  income  from  new  business  development.  Over  the  same  period, Ambac Assurance  performance  will  be  evaluated 
according to changes in a ratio or value of Ambac Assurance's assets relative to its insurance and financial obligations, which is intended to 
reward participants for increases in the relative value of Ambac Assurance.  Other than voluntary termination or involuntary termination for 
cause, and provided that a participant's employment with the Company is not terminated within the first year of the performance period (reduced 
to six months for the 2016 grant to employees other than executive officers), the performance awards shall partially vest as of the date of such 
termination in the proportion of the number of calendar days which have lapsed since the grant date and the denominator of which shall be 
the total number of calendar days of the original vesting period.  Settlements of all performance awards shall be within 60 days after the end 
of the performance period, including those that had a partial vesting.

In 2015, a performance award was granted to the former Chief Executive Officer.  This award will vest upon the emergence of the Segregated 
Account from rehabilitation (or a similar event as determined in the sole and absolute discretion of the Compensation Committee of Ambac's 
Board of Directors), provided that such emergence occurs no later than December 31, 2018.

17.        COMMITMENTS AND CONTINGENCIES 

Ambac is responsible for leases on the rental of office space. The executive office of Ambac is located in New York City under a lease agreement 
that was modified and extended in 2015 to allow Ambac to remain in the same office space through September 2019 and on one floor through 
the end of 2029, with an option to continue to occupy other currently leased floors through the end of 2029.  Rent payments under this lease 
made through September 2019 will result in the periodic reduction of Segregated Account Junior Surplus Notes that were previously issued 
to the landlord, beginning in January 2016.  Ambac leases additional space for its data center, disaster recovery site and for its international 
location  under lease agreements that expire periodically through October 2020. An estimate of future net minimum lease payments in each 
of the next five years ending December 31, and the periods thereafter, is as follows:

2014, respectively. 

The Segregated Account and Wisconsin Rehabilitation Proceeding

On March 24, 2010, Ambac Assurance established a segregated account (the “Segregated Account”) and allocated to the Segregated Account 
certain financial guaranty insurance policies and other contingent liabilities, certain claims and other rights, and certain equity interests in 
subsidiaries. An insurance rehabilitation proceeding (the “Rehabilitation Proceeding”) was commenced with respect to the Segregated Account 
in the Wisconsin Circuit Court for Dane County (the “Rehabilitation Court”) on March 24, 2010 by the Commissioner of Insurance of the 
State of Wisconsin (the “Commissioner”) and the Rehabilitation Court entered an order of rehabilitation for the Segregated Account, appointing 
the Commissioner as Rehabilitator, and entered orders enjoining certain actions that could have an adverse effect on the financial condition 
of the Segregated Account.

Various third parties filed motions or objections in the Rehabilitation Court and/or moved to intervene in the Segregated Account Rehabilitation 
Proceeding.  On  January 24,  2011,  the  Rehabilitation  Court  issued  its  Decision  and  Final  Order  Confirming  the  Rehabilitator’s  Plan  of 
Rehabilitation, with Findings of Fact and Conclusions of Law (the “Confirmation Order”). Notices of appeal from the Confirmation Order 
were filed by various parties, including policyholders. These appeals challenged various provisions of the Segregated Account Rehabilitation 
Plan and actions the Rehabilitator or the Wisconsin Commissioner of Insurance had taken in formulating the Segregated Account Rehabilitation 
Plan. These appeals from the Confirmation Order were consolidated with earlier-filed appeals challenging, among other things, the issuance 
of injunctive relief and a settlement between Ambac Assurance and various financial institutions. On October 24, 2013, the Wisconsin Court 
of Appeals affirmed the Confirmation Order and the Rehabilitation Court’s rejection of the objections filed by various third parties before 
entry of the Confirmation Order. On November 22, 2013, petitions seeking discretionary review of this ruling by the Wisconsin Supreme Court 
were filed by various parties. The Rehabilitator responded by opposing further review by the Wisconsin Supreme Court.   On March 17, 2014, 
the Supreme Court of Wisconsin denied the petitions for review making the decision by the Wisconsin Court of Appeals final and controlling 
law.

On June 9, 2014, the Rehabilitator filed in the Rehabilitation Court a motion to confirm and declare the reimbursement amounts due with 
respect to cash claim payments made by Ambac Assurance and the Segregated Account on two policies. Certain investors filed objections to 
the motion on July 2, 2014. On July 7, 2014, after a hearing on the motion, the Rehabilitation Court granted the Rehabilitator’s motion. On 
August 20, 2014, a group of investors filed a notice of appeal. On March 4, 2016, the Wisconsin Court of Appeals affirmed the Rehabilitation 
Court’s ruling. On March 24, 2016, a group of investors filed a motion for reconsideration asking the Wisconsin Court of Appeals to reverse 
its decision. The motion for reconsideration was denied on March 30, 2016.

On February 10, 2016, certain investors filed a motion in the Rehabilitation Court requesting an order directing the Rehabilitator to show 
cause why the Interim Payment Percentage as set forth in the Segregated Account Rehabilitation Plan, as amended, should not be substantially 
increased  and  distributions  promptly  made  to  all  holders.   A  hearing  on  the  motion  was  held  on  March  29,  2016.  On April  5,  2016,  the 
Rehabilitation Court entered an order denying the motion, granting the Rehabilitator’s motion to quash a related deposition notice, and requiring 
interested parties in the proceedings to obtain leave of court before seeking any discovery.

On July 15, 2016, the Rehabilitator filed a motion to confirm and declare the nature of the Segregated Account Rehabilitation Proceedings in 
order to avoid misunderstandings that may arise in litigation involving Ambac Assurance concerning certain military housing projects. Certain 
parties to these military housing litigations filed an opposition to the Rehabilitator’s motion on September 30, 2016. On October 11, 2016 the 
Rehabilitation Court held a hearing on the motion and on October 24, 2016, the Rehabilitation Court entered an order granting the Rehabilitator’s 
motion.  On November 7, 2016, the interested parties that had opposed the Rehabilitator’s motion filed a notice of appeal from the October 
24 order, and filed their opening brief in support of this appeal on January 17, 2017.  The Rehabilitator filed a response brief in the Wisconsin 
Court of Appeals on February 15, 2017.  On November 21, 2016, the Rehabilitator filed a motion to quash a subpoena served on the Wisconsin 
Commissioner of Insurance by certain parties to the military housing litigations.  The Rehabilitation Court granted the Rehabilitator’s motion 
to quash on November 23, 2016.  The interested parties that had served the subpoena filed an opposition to the Rehabilitator’s motion to quash

on November 23, 2016, and filed on November 28, 2016 a motion to reconsider the November 23 order, which the Rehabilitator opposed on 
December 6, 2016.  The Rehabilitation Court held a hearing on January 6, 2017 and entered an order on January 20, 2017 denying the motion 
to reconsider and clarifying procedures for discovery relating to the Segregated Account Rehabilitation Proceedings.

Litigation Against Ambac

Ori Wilbush, individually and on behalf of all others similarly situated v. Ambac Financial Group, Inc., Diana N. Adams, David Trick, Jeffrey 
S. Stein, Nader Tavakoli and Cathleen Matanle (United States District Court, Southern District of New York, Civil Action No. 16-cv-05076-
RMB, filed on June 28, 2016). A putative securities class action lawsuit was filed in June 2016 against Ambac and certain of its present and 
former officers and directors, for alleged violations of the federal securities laws. The court appointed a lead plaintiff on October 11, 2016.  
The lead plaintiff filed an Amended Class Action Complaint on November 23, 2016.  The suit purports to be on behalf of purchasers of Ambac’s 
securities from November 13, 2013 through November 17, 2015. It alleges, among other things, that defendants issued materially false and 
misleading statements regarding Ambac’s (a) risk management and credit rating policies and procedures, (b) credit mitigation strategies, (c) 
internal controls over financial reporting, and (d) loss exposures on its public finance bond portfolio. In particular, the suit alleges that defendants 
did  not  sufficiently  disclose Ambac’s  exposure  to  bonds  issued  by  the  Commonwealth  of  Puerto  Rico,  despite  allegedly  being  aware  of 
significant risks associated with those exposures. Defendants filed a motion to dismiss the amended complaint on February 27, 2017. Ambac 
believes the lawsuit is without merit.

County of Alameda et al. v. Ambac Assurance Corporation et al. (Superior Court of the State of California, County of San Francisco, second 
amended complaint filed on or about August 23, 2011) (“Alameda Complaint”); Contra Costa County et al. v. Ambac Assurance Corporation 
et al. (Superior Court of the State of California, County of San Francisco, third amended complaint filed on or about October 21, 2011) (“Contra 
Costa Complaint”); The Olympic Club v. Ambac Assurance Corporation et al. (Superior Court of the State of California, County of San 
Francisco, fourth amended complaint filed on or about October 21, 2011) (“Olympic Club Complaint”). The Contra Costa Complaint was 
brought on behalf of five California municipal entities and the non-profit Jewish Community Center of San Francisco. The Alameda Complaint 
was brought on behalf of nineteen California municipal entities. The Olympic Club Complaint was brought on behalf of the non-profit Olympic 
Club.  The  three  actions  make  similar  allegations  against Ambac Assurance,  various  other  financial  guarantee  insurance  companies  and 
employees thereof (collectively with Ambac Assurance, the “Bond Insurer Defendants”), and, in the case of the Contra Costa Complaint and 
the Olympic Club Complaint, the major credit rating agencies (the “Rating Agencies”). The actions allege that (1) Ambac Assurance and the 
other Bond Insurer Defendants colluded with the Rating Agencies to perpetuate a “dual rating system” pursuant to which the Rating Agencies 
rated the debt obligations of municipal issuers differently from corporate debt obligations, thereby keeping municipal ratings artificially low 
relative to corporate ratings; (2) Ambac Assurance and the other Bond Insurer Defendants issued false and misleading financial statements 
and failed to disclose the extent of the insurers’ respective exposures to mortgage-backed securities and collateralized debt obligations; and 
(3) as a result of these actions, plaintiffs incurred higher interest costs and bond insurance premiums in respect of their respective bond issues. 
Ambac Financial Group was originally a defendant in each of these actions, but on November 22, 2010, Ambac Financial Group was dismissed 
without prejudice as a defendant by the plaintiffs in each of these actions. Ambac Assurance and the other Bond Insurer Defendants filed a 
demurrer seeking dismissal of the current amended complaints on September 21, 2011, which was denied on October 20, 2011. On December 2, 
2011, Ambac Assurance and the other Bond Insurer Defendants filed a special motion to strike the current amended complaints under California’s 
Anti-SLAPP statute (Calif. Code of Civ. Proc. Section 425.16). A hearing on the motion was held on March 23, 2012. On May 1, 2012, the 
Court ruled that the complaints were governed by the Anti-SLAPP statute to the extent they alleged conspiracy to influence the rating agencies’ 
rating methodologies, but not to the extent that the complaints alleged false or misleading statements or nondisclosures. After oral argument 
on March 21, 2013, the court dismissed claims related to the conspiracy branch of the complaint under the California Antitrust Law (the 
Cartwright Act) and after oral argument on April 22, 2013 denied defendants’ motion to dismiss claims under the California Unfair Competition 
Law. The court entered an order to this effect on July 9, 2013. On February 18, 2016 the California Court of Appeal, First District, issued a 
decision reversing the lower court’s dismissal of the Cartwright Act claim as against Ambac Assurance and otherwise affirming the lower 
court’s decision as to Ambac Assurance.  Discovery has commenced. 

Ambac Assurance is defending several lawsuits in which borrowers have brought declaratory judgment actions claiming, among other things, 
that Ambac Assurance’s claims for specific performance related to the construction and development of housing at various military bases to 
replace or cash-fund a debt-service-reserve surety bond, as required under the applicable loan documents (see Litigation Filed By Ambac), 
are time-barred or are barred by the doctrine of laches, that Ambac lacks standing on the basis that there has been an “Ambac Default,” and 
that Ambac is not entitled to specific performance pursuant to the terms of the loan documents.  Specifically, Ambac Assurance is a defendant

•  Monterey Bay Military Housing LLC and Monterey Bay Land LLC v. Ambac Assurance Corporation (Superior Court, Monterey 
County, California, Case No. 15CV000599).  Plaintiff filed this action on December 4, 2015.  Ambac Assurance filed an answer on 
January 19, 2016.

Ambac Assurance’s estimates of projected losses for RMBS transactions consider, among other things, the RMBS transactions’ payment 
waterfall structure, including the application of interest and principal payments and recoveries, and depend in part on our interpretations of 
contracts and other bases of our legal rights.  From time to time, bond trustees and other transaction participants have employed different 
contractual interpretations. It is not possible to predict whether additional disputes will arise, nor the outcomes of any potential litigation.  It 
is possible that there could be unfavorable outcomes in this or other disputes or proceedings and that our interpretations may prove to be 
incorrect, which could lead to changes to our estimate of loss reserves.

Ambac Assurance has periodically received various regulatory inquiries and requests for information with respect to investigations and inquiries 
that such regulators are conducting. Ambac Assurance has complied with all such inquiries and requests for information.

Ambac is involved from time to time in various routine legal proceedings, including proceedings related to litigation with present or former 
employees. Although Ambac’s litigation with present or former employees is routine and incidental to the conduct of its business, such litigation 
can result in large monetary awards when a civil jury is allowed to determine compensatory and/or punitive damages for, among other things, 
termination of employment that is wrongful or in violation of implied contracts.

It is not reasonably possible to predict whether additional suits will be filed or whether additional inquiries or requests for information will 
be made, and it is also not possible to predict the outcome of litigation, inquiries or requests for information. It is possible that there could be 
unfavorable outcomes in these or other proceedings. Legal accruals for litigation against Ambac which are probable and reasonably estimable, 
and management's estimated range of loss for such matters, are not material to the operating results or financial position of the Company. For 
the litigation matters Ambac is defending that do not meet the “probable and reasonably estimable” accrual threshold and where no loss 
estimates have been provided above, management is unable to make a meaningful estimate of the amount or range of loss that could result 
from unfavorable outcomes. Under some circumstances, adverse results in any such proceedings could be material to our business, operations, 
financial position, profitability or cash flows. The Company believes that it has substantial defenses to the claims above and, to the extent that 
these actions proceed, the Company intends to defend itself vigorously; however, the Company is not able to predict the outcomes of these 
actions.

Litigation Filed by Ambac

In the ordinary course of their businesses, certain of Ambac’s subsidiaries assert claims in legal proceedings against third parties to recover 
losses already paid and/or mitigate future losses. The amounts recovered and/or losses avoided which may result from these proceedings is 
uncertain, although recoveries and/or losses avoided in any one or more of these proceedings during any quarter or fiscal year could be material 
to Ambac’s results of operations in that quarter or fiscal year.

Erste Europäische Pfandbriefund Kommunalkreditbank AG In Luxemburg and Ambac Assurance Corporation v. City of San Bernardino, 
California (United States Bankruptcy Court, Central District of California, Riverside Division, Docket No. 15-1185, filed on January 7, 2015).  
Plaintiffs  commenced  this  adversary  proceeding,  which  relates  to  the  Debtor’s  obligations  under  the  Public  Employees  Retirement Law, 
California Government Code Section 20000 et seq. (the “Retirement Law”), in connection with the City of San Bernardino’s bankruptcy 
proceeding.  In the complaint, plaintiffs seek a declaratory judgment that the Debtor is obligated to make equivalent payments to both the 
holders of certain pension obligation bonds (the “Bonds”), a portion of which are insured by Ambac, and the California Public Employees 
Retirement Systems (“CalPERS”) to fund pension and other retirement benefits.  It is the plaintiffs’ position that they are entitled to declaratory 
judgment because (i) when the City issue the Bonds, the City argued and a California court found, that the obligations under the Bonds were 
of the same legal character as the City’s obligations to CalPERS and (ii) the amounts owed to the bondholders are to CalPERS are merely 
separate portions of a single obligation owed by the Debtor under the Retirement Law. Plaintiffs therefore seek equivalent payment as to 
CalPERS, whether such payment takes for the form of current payments during the bankruptcy proceeding and thereafter, payments otherwise 
made in connection with the Retirement Law or any agreements entered into in accordance therewith, or distributions under a plan of adjustment. 
On March 13, 2015, the City filed a motion to dismiss the complaint, which plaintiffs opposed. On May 11, 2015, the court heard oral argument 
and granted the City’s motion to dismiss. On June 8, 2015, plaintiffs filed a notice of appeal of the court’s order granting the City’s motion to 
dismiss with the Bankruptcy Appellate Panel for the Ninth Circuit and filed their appellate brief on January 5, 2016. The parties have reached 
a settlement and pursuant to the settlement agreement dated March 28, 2016, the plaintiffs have agreed to dismiss the appeal with prejudice 
upon confirmation of the City’s plan of adjustment by the bankruptcy judge and the plan of adjustment becoming effective.

Ambac UK v. J.P. Morgan Investment Management (Supreme Court of the State of New York, County of New York, filed May 4, 2009, No. 
650259/2009).  Ambac UK commenced this action against J.P. Morgan Investment Management asserting claims for breach of contract, breach 
of fiduciary duty and gross negligence relating to defendant’s mismanagement of assets supporting bonds issued by Ballantyne Plc and insured 
by Ambac UK that funded excess reserves for term life insurance required by regulation.  (Pursuant to an agreement with Ballantyne Plc, 
Ambac UK was given the authority to prosecute Ballantyne plc's claims against J.P. Morgan Investment Management.) On March 24, 2010, 
the court granted defendant's motion to dismiss the complaint.  Ambac UK appealed the March 2010 decision and on July 14, 2011, the 
Appellate Division for the First Department reversed the decision and reinstated Ambac UK's claims in their entirety.  Fact and expert discovery

have been completed.  On January 22, 2016, Ambac UK filed a motion for partial summary judgment seeking a ruling that defendant breached 
the Investment Management Agreement between JPMIM and Ballantyne plc under one of the asserted theories of liability. JPMIM opposed 
the motion. On February 21, 2017, the court issued a decision that JPMIM had not complied with the contractual provision at issue in the 
motion, but also decided that an issue of fact remained as to whether such breach violated the standard of care set forth in the investment 
management agreement and, therefore, denied the motion. Trial is scheduled to begin in March 2017.

Assured Guaranty Corp., Assured Guaranty Municipal Corp., and Ambac Assurance Corporation v. Alejandro Garcia Padilla, et al. (United 
States District Court, District of Puerto Rico No. 3:16-cv-01037, filed on January 7, 2016). Ambac Assurance, along with co-plaintiffs Assured 
Guaranty Corp. and Assured Guaranty Municipal Corp., filed a complaint for declaratory and injunctive relief to protect its rights against the 
illegal clawback of certain revenue by the Commonwealth of Puerto Rico. Defendants (including the Government Development Bank (“GDB”) 
President but solely in her capacity as a member of the Working Group For The Fiscal and Economic Restoration of Puerto Rico) filed a 
motion to dismiss for lack of subject matter jurisdiction on January 29, 2016.  The GDB President, in her official capacity, moved to dismiss 
for failure to state a claim upon which relief can be granted on January 29, 2016. Plaintiffs filed their oppositions to the motions on February 
16, 2016 and defendants filed replies on February 23, 2016.  This case was administratively consolidated with a similar case before the same 
judge, Financial Guaranty Insurance Company v. Alejandro Garcia Padilla, et al. (United States District Court, District of Puerto Rico No. 
3:16-cv-01095). On October 4, 2016, the court denied the Defendants’ and GDB President’s motions to dismiss with respect to all claims 
asserted by Ambac Assurance and Assured. On October 14, 2016, Defendants filed a Notice of Automatic Stay, asserting that Plaintiffs’ claims 
have been rendered moot and further asserting that the case is automatically stayed under section 405 of the Puerto Rico Oversight, Management 
and Economic Stability Act (“PROMESA”). On October 28, 2016, Plaintiffs informed the court that neither party was currently challenging 
the stay, and expressly reserved their right to seek to lift the stay at any time.  Plaintiffs also objected to Defendants’ assertion that the case 
should be dismissed as moot.

Ambac Assurance Corporation v. Puerto Rico Highways and Transportation Authority (United States District Court, District of Puerto Rico, 
No. 16-cv-1893).  Ambac Assurance filed a complaint against the Puerto Rico Highways and Transportation Authority (“PRHTA”) on May 
10, 2016, alleging breach of fiduciary duty and breach of contract in connection with PRHTA’s extension of an existing toll road concession 
agreement. The complaint alleges that it was inappropriate for PRHTA to enter into the extension agreement in its current state of financial 
distress because PRHTA has no control over, and is unlikely to receive, the proceeds of the transaction.  The complaint also seeks specific 
performance of PRHTA’s contractual duty to provide information requested by Ambac Assurance under documents related to PRHTA bonds 
insured by Ambac Assurance. Ambac Assurance filed related motions seeking the appointment of a provisional receiver for PRHTA and 
expedited discovery.  In addition to those remedies, Ambac Assurance seeks an order of the court that would, among other things, compel 
PRHTA to allow Ambac Assurance to inspect PRHTA’s financial records on an ongoing basis and permanently enjoin PRHTA from committing 
further breaches of its fiduciary and contractual duties. On July 1, 2016, PRHTA filed an Emergency Notice of Stay, asserting that the case 
was automatically stayed under section 405 of PROMESA. Ambac Assurance filed a response on July 11, 2016, disagreeing that the PROMESA 
stay applies but electing not to contest the stay at such time and reserving the right to challenge it or to seek to lift the stay in the future. Ambac 
Assurance also asserted that PRHTA still is obligated to make available to Ambac Assurance certain information, notwithstanding the stay on 
litigation  and  provided  a  proposed  order  for  the  court  to  issue.  PRHTA  filed  a  reply  on  July  18,  2016,  contesting Ambac Assurance’s 
characterization, and provided an alternative order for the court to issue. Ambac Assurance’s response was filed July 25, 2016. PRHTA also 
filed an Urgent Motion to Exempt PRHTA from Outstanding Filings in the case during the pendency of the stay, which was granted. On August 
23, 2016 the court issued an order staying the case, and requesting that Ambac Assurance and PRHTA notify the court whether each would 
seek to assert cause to lift the stay. On August 26, 2016, both Ambac Assurance and PRHTA informed the court that neither was currently 
seeking to lift the stay; however, Ambac Assurance expressly reserved its right to seek to lift the stay at any time.

Lex Claims, LLC et al. v. Alejandro Garcia Padilla et al. (United States District Court, District of Puerto Rico, No. 16-2374). On October 7, 
2016, certain General Obligation bondholder plaintiffs in an action to which Ambac Assurance is not currently a party filed a motion for leave 
to amend their complaint and for partial relief from the PROMESA stay. Plaintiffs’ proposed second amended complaint adds the Puerto Rico 
Sales Tax Financing Corporation (“COFINA”), COFINA’s executive director, and the trustee for the COFINA bonds as defendants, and asserts 
numerous claims that challenge the legal validity of the COFINA structure and seek injunctive relief requiring the sales and use tax proceeds 
securing COFINA’s bonds to be transferred to the Puerto Rico Treasury. The plaintiffs contend that many of the claims challenging COFINA 
are not subject to PROMESA’s litigation stay provisions. On October 24, 2016, the defendants filed an opposition to the motion for leave to 
amend, arguing that the entire action is subject to the PROMESA stay. On October 26, 2016, Ambac Assurance filed a motion for leave to 
intervene and in support of the PROMESA stay. Ambac Assurance seeks to intervene principally to argue that the claims challenging COFINA 
are stayed by PROMESA, but also reserves the right to move to dismiss or otherwise defend against those claims should the court determine 
they are not stayed. The court has not ruled yet on plaintiffs’ motion for leave to amend or Ambac Assurance’s motion to intervene.  On 
November 4, 2016, the Court granted Plaintiffs’ motion for leave to amend.  Plaintiffs filed their second amended complaint that same day. 
On November 7, 2016, the government defendants sought to stay the case. On November 29, 2016, the parties’ briefing on Ambac Assurance’s 
motion to intervene was complete. Other putative intervenors filed motions to intervene. On February 17, 2017, the court granted the motions 
to intervene by Ambac Assurance and some of the other movants.  The court also denied the defendants’ motion to stay and the arguments in 
support of the stay filed by the intervenors, including Ambac Assurance.

Ambac Assurance has filed various lawsuits seeking specific performance of obligations of borrowers on loans related to the construction and 
development of housing at various military bases to replace or cash-fund a debt-service-reserve surety bond provided by Ambac Assurance, 
as required under the applicable loan documents.   Specifically, Ambac Assurance has instituted the following actions: 

•  Ambac Assurance Corporation v. Riley Communities, LLC (District Court, Shawnee County Kansas, No. 2016-CV-00026).  Ambac

Index No. 15-CV-9596).  Ambac Assurance filed this action on November 19, 2015.  On January 4, 2016, defendant moved to dismiss 
for failure to join an indispensable party, which Ambac Assurance opposed on January 25, 2016. On June 29, 2016, the court denied 
defendant’s motion to dismiss and granted Ambac Assurance leave to file an amended complaint, which was filed on July 13, 2016.

opposed the motion.

County, Pennsylvania, No. 2015-6348).  Ambac Assurance filed a summons on December 15, 2015 and a complaint on January 11, 
2016. On February 1, 2016, defendant served its answer.

•  Ambac  Assurance  Corporation  v.  Fort  Lee  Commonwealth  Communities,  LLC  (Circuit  Court,  Roanoke  City,  Virginia,  No.

In connection with Ambac Assurance’s efforts to seek redress for breaches of representations and warranties and fraud related to the information 
provided by both the underwriters and the sponsors of various transactions and for failure to comply with the obligation by the sponsors to 
repurchase ineligible loans, Ambac Assurance has filed various lawsuits:

•  Ambac Assurance Corporation and The Segregated Account of Ambac Assurance Corporation v. First Franklin Financial Corporation, 
Bank of America, N.A., Merrill Lynch, Pierce, Fenner & Smith Inc., Merrill Lynch Mortgage Lending, Inc., and Merrill Lynch Mortgage 
Investors, Inc. (Supreme Court of the State of New York, County of New York, Case No. 651217/2012, filed April 16, 2012). Ambac 
Assurance alleges breach of contract, fraudulent inducement, indemnification, reimbursement and requested the repurchase of loans 
that breach representations and warranties as required under the contracts, as well as damages. Defendants filed a motion to dismiss 
on July 13, 2012, which Ambac opposed on September 21, 2012. Oral argument was held on May 6, 2013. On July 18, 2013 the court 
dismissed Ambac Assurance’s claims for indemnification and limited Ambac Assurance’s claim for breach of loan-level warranties to 
the repurchase protocol, but did not dismiss Ambac Assurance’s other contractual claims or fraudulent inducement claim. On August 21, 
2013, defendants filed a notice of appeal, and on August 30, 2013, Ambac Assurance filed a notice of cross-appeal. On April 22, 2014, 
the parties filed a stipulation withdrawing defendants’ appeal and Ambac Assurance’s cross-appeal of the court’s July 18, 2013 decision.  
Discovery is ongoing.

•  Ambac Assurance  Corporation  and  The  Segregated Account  of Ambac Assurance  Corporation  v.  Countrywide  Securities  Corp., 
Countrywide Financial Corp. (a k.a. Bank of America Home Loans) and Bank of America Corp. (Supreme Court of the State of New 
York, County of New York, Case No. 651612/2010, filed on September 28, 2010). Ambac Assurance filed an Amended Complaint on 
September 8, 2011. Ambac Assurance alleged breach of contract, fraudulent inducement, indemnification and reimbursement, and 
breach of representations and warranties, requested the repurchase of loans that breach representations and warranties as required under 
the contracts, as well as damages, and asserted a successor liability claim against Bank of America. On May 28, 2013, Ambac Assurance 
filed a Second Amended Complaint adding an alter ego claim against Bank of America alleging that, because Bank of America and 
Countrywide are alter egos of one another, Bank of America is responsible for Countrywide’s liabilities to Ambac. The defendants 
served their answers on July 31, 2013. Fact and expert discovery has ended. On May 1, 2015, Ambac Assurance filed motions for 
partial summary judgment, which defendants opposed. Defendants also each filed motions for summary judgment, which Ambac 
Assurance opposed. The court heard oral argument on July 15, 2015. On October 27, 2015, the court issued a decision dated October 
22, 2015 granting in part and denying in part the parties’ respective summary judgment motions regarding Ambac Assurance’s claims 
against Countrywide (primary-liability claims), and issued a second decision granting Ambac Assurance’s partial motion for summary 
judgment and denying Bank of America’s motion for summary judgment regarding Ambac Assurance’s secondary-liability claims 
against Bank of America. Ambac Assurance and Countrywide filed notices of appeal of the October 22, 2015 decision relating to 
primary liability and Bank of America filed a notice of appeal of the October 27, 2015 decision relating to its secondary-liability to

material breach of contract and for the repurchase of loans that breach representations and warranties under the contracts, as well as 
damages. On October 31, 2014 defendants filed a motion to strike the amended complaint. Ambac Assurance opposed that motion and 
at the court’s recommendation also filed a cross motion for leave to amend the complaint on November 14, 2014, which the defendants 
opposed.  Defendants filed a motion to dismiss the fraudulent inducement claim, which Ambac Assurance opposed.  The court heard 
oral argument on the defendants’ motion to dismiss the fraudulent inducement claim on April 14, 2015. On June 3, 2015, the court 
denied  defendants’  July  2013  motion  to  dismiss Ambac’s  claim  for  breaches  of  representations  and  warranties,  but  granted  the

On December 29, 2016, the court issued a decision denying Nomura’s motion to strike Ambac’s amended complaint and its motion to

The  Segregated Account  of Ambac Assurance  Corporation  and Ambac Assurance  Corporation  v.  Countrywide  Home  Loans,  Inc. 
(Wisconsin Circuit Court for Dane County, Case No 14 CV 3511, filed on December 30, 2014).  Ambac Assurance alleges a claim for 
fraudulent inducement in connection with Ambac Assurance’s issuance of insurance policies relating to five residential mortgage-
backed securitizations that are not the subject of Ambac Assurance’s previously filed lawsuit against the same defendant. Defendant 
filed a motion to dismiss the complaint on February 20, 2015, which Ambac Assurance opposed. The court heard oral argument on 
two of Countrywide’s grounds for dismissal on June 23, 2015, and indicated that it would dismiss the Wisconsin Action without 
prejudice for lack of personal jurisdiction. The court issued an order to that effect on July 2, 2015. Ambac Assurance appealed the July 
2, 2015 order. On June 23, 2016, the Wisconsin Court of Appeals reversed the dismissal of the complaint, and on October 11, 2016, 
the Wisconsin Supreme Court granted Countrywide’s petition for review of the June 23 decision by the Wisconsin Court of Appeals.  
The Wisconsin Supreme Court  appeal is fully briefed and scheduled for oral argument on February 28, 2017. On June 30, 2015, 
plaintiffs filed a Summons with Notice in the Supreme Court of the State of New York, County of New York, No. 652321/15 (the 
“2015 New York Action”), alleging claims identical to the Wisconsin Action. On July 21, 2015, plaintiffs filed a complaint in the 2015 
New York Action and a motion to stay the 2015 New York Action pending appeal and litigation of the Wisconsin Action. On August 
5, 2015, Countrywide filed its opposition to plaintiffs’ motion to stay and on August 10, 2015, Countrywide filed a motion to dismiss 
the complaint, which Ambac opposed. The court held oral argument in November 2015 and on September 20, 2016 granted Ambac 
Assurance’s motion to stay. Countrywide’s motion to dismiss the complaint is held in abeyance pending resolution of the Wisconsin 
Action.

Countrywide Securities Corp., Countrywide Financial Corp., and Bank of America Corp. (Supreme Court of the State of New York, 
County of New York, Case No. 653979/2014, filed on December 30, 2014).  Ambac Assurance alleges a claim for fraudulent inducement 
in connection with Ambac Assurance’s issuance of insurance policies relating to eight residential mortgage-backed securitizations that 
are not the subject of Ambac Assurance’s previously filed lawsuits against the same defendants.  On February 20, 2015, the Countrywide 
defendants filed a motion to dismiss the complaint, which Bank of America joined on February 23, 2015.  Ambac Assurance opposed 
the motion. On December 20, 2016, the court issued a decision denying the defendants’ motion to dismiss..  Discovery is ongoing. 

•  Ambac Assurance Corporation and The Segregated Account of Ambac Assurance Corporation v. U.S. Bank  National Association

commenced this action to enjoin the defendant from accepting a proposed settlement in a separate litigation that the defendant is 
prosecuting, as trustee, in connection with a residential mortgage-backed securitization for which Ambac Assurance issued an insurance 
policy.  Ambac Assurance alleges claims for declaratory judgment, breach of contract, breach of fiduciary duty, and violation of the 
Streit Act.  On February 14, 2017, plaintiffs filed an amended complaint asserting additional claims for declaratory judgment and 
breach of contract related to the defendant’s treatment of trust recoveries. The defendant has not yet responded to Ambac Assurance’s 
amended complaint.

Other Litigation

U.S. Securities and Exchange Commission (the “SEC”) v. Citigroup Global Markets Inc. (“Citigroup”) (United States District Court Southern 
District of New York, Docket No. 11-CV-7387, filed in October 2011). This suit related to a collateralized debt obligation transaction arranged 
by Citigroup where Ambac Credit Products, LLC (insured by Ambac Assurance) provided credit protection through a credit default swap to 

a bank counterparty that was exposed to the transaction. The SEC and Citigroup reached a settlement of this action for $285,000. Judge Rakoff,
the presiding judge, approved the settlement in August of 2014. We have been informed by the SEC that they intend to make a motion to Judge 
Rakoff for approval of the distribution of the funds to aggrieved parties. Judge Rakoff must approve the SEC’s proposed allocation. While 
there can be no assurance as what the SEC’s proposed allocation will be or the timing or substance of what Judge Rakoff will decide, Ambac 
Assurance expects to receive a significant portion of the settlement funds. Ambac has not recorded any receivable for its estimated portion of 
these settlement funds.

18.        SEGMENT INFORMATION 

Ambac has two reportable segments, as follows: (i) Financial Guarantee, which provides financial guarantees (including credit derivatives) 
for public finance, structured finance and international obligations; and (ii) Financial Services, which provides investment agreements, funding 
conduits, and interest rate swaps, principally to clients of the financial guarantee business. Ambac’s reportable segments were strategic business 
units that offered different products and services.

Ambac Assurance guarantees the swap and investment agreement obligations of its Financial Services subsidiaries. Additionally, Ambac 
Assurance provides loans to the Financial Services businesses. Inter-segment revenues include the premiums and investment income earned 
under those agreements. 

Information provided below for unaffiliated “Corporate and Other” primarily relates to investment income on Ambac's investment portfolio.  
Equity in net income of investees accounted for by the equity method relates to the Owner Trust Certificate received when Ambac deposited 
its Segregated Account junior surplus note into a Trust (see Note 3. Special Purpose Entities, Including Variable Interest Entities for further 
information relating to the sale by Ambac of a junior surplus note issued to it by the Segregated Account).  Inter-segment for "Corporate and 
Other" relates to amounts received by Ambac under the Mediation Agreement dated September 21, 2011 (as more fully described in Note 1. 
Background and Business Description), including accrual of interest on the junior surplus notes issued by the Segregated Account prior to 
Ambac's deposit into a Trust.

Item 9.  Changes 
Accountants on Accounting and Financial Disclosure.

in  and  Disagreements  with 

None.

Item 9A.   Controls and Procedures.

Evaluation  of  Disclosure  Controls  and  Procedures. Ambac’s 
disclosure  controls  and  procedures  are  designed  to  ensure  that 
information required to be disclosed under the Securities Exchange 
Act of 1934, as amended, is recorded, processed, summarized and 
reported within the time periods specified in the SEC’s rules and 
forms, including without limitation that information required to be 
disclosed  by  Ambac  in  its  SEC  filings  is  accumulated  and 
communicated  to  management,  including  the  Chief  Executive 
Officer (CEO) and Chief Financial Officer (CFO) as appropriate 
to allow for timely decisions regarding required disclosure. 

Ambac’s Disclosure Committee assists the CEO and CFO in their 
responsibilities  to  design,  establish,  maintain  and  evaluate  the 
effectiveness  of  disclosure  controls  and  procedures.  The 
Disclosure Committee is responsible for, among other things, the 
oversight,  maintenance  and  implementation  of  the  disclosure 
controls and procedures, subject to the supervision and oversight 
of the CEO and CFO. Ambac’s management, with the participation 
of its CEO and CFO, has evaluated the effectiveness of Ambac’s 
disclosure controls and procedures (as defined in Rule 13a-15(e) 
under the Securities Exchange Act of 1934) as of December 31, 
2016  and,  the  CEO  and  CFO  have  concluded  that  at  that  date 
Ambac’s disclosure controls and procedures were effective at the 
reasonable assurance level.

Management’s  Report  on  Internal  Control  Over  Financial 
Reporting.  Management of Ambac is responsible for establishing 
and maintaining adequate internal control over financial reporting. 
Ambac’s  internal  control  over  financial  reporting  is  a  process 
designed under the supervision of the CEO and CFO and overseen 
by Ambac’s Board of Directors to provide reasonable assurance 
regarding the reliability of financial reporting and the preparation 
of Ambac’s financial statements for external reporting purposes in 
accordance  with  U.S.  generally  accepted  accounting  principles. 
Ambac’s internal control over financial reporting includes those 
policies  and  procedures  that  (i)  pertain  to  the  maintenance  of 
records that, in reasonable detail, accurately and fairly reflect the 
transactions  and  dispositions  of  assets  of  Ambac;  (ii)  provide 
reasonable assurance that transactions are recorded as necessary 
to permit preparation of financial statements in accordance with 
U.S. generally accepted accounting principles, and that receipts 
and  expenditures  of  the  company  are  being  made  only  in 
accordance with authorizations of management and directors of 
Ambac;  and  (iii)  provide  reasonable  assurance  regarding  the 
prevention or timely detection and remediation of unauthorized 
acquisition, use or disposition of Ambac’s assets that could have 
a material effect on the financial statements.

Because of its inherent limitations, internal control over financial 
reporting  may  not  prevent  or  detect  misstatements.  Also, 
projections of any evaluation of effectiveness to future periods are 
subject to the risk that controls may become inadequate because 
of changes in conditions, or that the degree of compliance with the 
policies or procedures may deteriorate.

Ambac management conducted an assessment of the effectiveness 
of Ambac’s internal control over financial reporting based on the 

criteria  established  in  the  2013  Internal  Control  -  Integrated 
Framework issued by the Committee of Sponsoring Organizations 
of the Treadway Commission (COSO).

Ambac management has concluded that, as of December 31, 2016, 
our internal control over financial reporting was effective based 
on the criteria articulated in the 2013 Internal Control - Integrated 
Framework. The effectiveness of our internal control over financial 
reporting as of December 31, 2016 has been audited by KPMG 
LLP, an independent registered public accounting firm, as stated 
in  their  report,  which  expressed  an  unqualified  opinion  on  the 
effectiveness of Ambac’s internal control over financial reporting.  

Remediation of Prior Material Weakness in Internal Control 
over Financial Reporting.  During management’s evaluation of 
disclosure  controls  and  procedures  as  of  December  31,  2015,  a 
material weakness in internal control over financial reporting was 
identified.  Specifically, management concluded that they did not 
sufficiently evaluate the design and operating effectiveness of the 
general information technology controls over modeling performed 
by a third party service provider, of residential mortgage backed 
collateral losses within certain securitizations that have insurance 
policies  issued  by  Ambac.  This  included  the  late  receipt  and 
evaluation of the servicer’s annual Service Organization Control 
report (“SOC-1 report”) attesting to the design and effectiveness 
of  the  Service  Organization’s  general  information  technology 
(“IT”)  controls,  subsequent  to  the  issuance  of  our  fiscal  2015 
Annual Report on Form 10-K. As a result, our controls over the 
estimate of loss reserves and subrogation recoverables, investment 
income  and  assessing  other  than  temporary  impairment  for 
purchased  residential  mortgage  backed  securities  were  not 
designed in a manner that would enable us to prevent or detect and 
correct  a  potential  material  misstatement  to  the  consolidated 
financial statements at December 31, 2015.

Since the time of its identification, management has been actively 
engaged in the implementation of remediation efforts to address 
that material weakness.  Remediation efforts included the timely 
receipt  of  the  servicer’s  SOC-1  report  as  well  as  obtaining  an 
Ambac specific attestation report, both providing an unqualified 
opinion from the servicer’s auditor,  which allow Ambac to assess 
the design and operating effectiveness of the servicer’s IT controls.  
Additionally,  Ambac  enhanced  its  internal  controls  with  the 
addition of new controls and increasing the precision of certain 
existing  controls  relating  to  the  estimate  of  loss  reserves  and 
subrogation recoverables, investment income and assessing other 
than  temporary  impairment  for  purchased  residential  mortgage 
backed  securities.  As  of  December 31,  2016,  management 
concluded, subject to the supervision and oversight of the CEO 
and CFO, that the previously disclosed material weakness had been  
remediated. 

Changes in Internal Control Over Financial Reporting.  Except 
as noted above relative to the remediation of the prior year material 
weakness, there were no changes in Ambac’s internal control over 
financial reporting (as such term is defined in Rules 13a-15(f) and 
15d-15(f) under the Exchange Act) during the fourth quarter of 
2016  that  have  materially  affected,  or  are  reasonably  likely  to 
internal  control  over  financial 
materially  affect,  Ambac’s 
reporting.

AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES
SCHEDULE II— CONDENSED FINANCIAL INFORMATION
OF REGISTRANT (PARENT COMPANY ONLY)
Notes to Condensed Financial Information
(Dollar Amounts in Thousands)

The condensed financial information of Ambac Financial Group, Inc. (“Ambac” or the “Registrant”) as of December 31, 2016 and 2015 and 
for the three years in the period ended December 31, 2016, should be read in conjunction with the consolidated financial statements of Ambac 
Financial Group, Inc. and Subsidiaries and the notes thereto included in this 2016 Annual Report on Form 10-K for the year ended December 31, 
2016.

Ambac, headquartered in New York City, is a financial services holding company incorporated in the state of Delaware on April 29, 1991. On 
May 1, 2013 (the “Effective Date”), Ambac emerged from Chapter 11 bankruptcy protection when the Second Modified Fifth Amended Plan 
of Reorganization of Ambac (the “Reorganization Plan”) became effective. On December 26, 2013, the United States Bankruptcy Court for 
the Southern District of New York (the “Bankruptcy Court”) entered an order of final decree closing Ambac’s Chapter 11 case. Ambac filed 
a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code in the Bankruptcy Court on November 8, 2010 as a 
result of losses incurred since the beginning of the financial crisis in 2007.

Income Taxes

Ambac files a consolidated Federal income tax return with its U.S. subsidiaries. Ambac and its subsidiaries also file separate or combined 
income tax returns in various states, local and foreign jurisdictions. As of December 31, 2016 Ambac had loss carryforwards totaling $4,027,329. 
This includes carryforwards of $74,094 relating to U.S. capital losses and $3,953,235  relating to U.S. federal net operating losses, which, if 
not utilized, will begin expiring in 2029, and will fully expire in 2033.  The NOL allocable to AFG as of December 31, 2016 is $1,389,359.

As discussed more fully in Note 1. Background and Business Description — Chapter 11 Reorganization of Ambac, under the Amended Plan 
Settlement, the Registrant, Ambac Assurance and certain affiliates entered into an amended and restated tax sharing agreement (the “Amended 
TSA”).  Pursuant to the Amended TSA, to the extent Ambac Assurance generated taxable income after September 30, 2011, which offset the 
allocated $3,650,000 of NOLs, (or the proportionate amount of AMT NOL (as defined)), it is obligated to make payments (“Tolling Payments”), 
subject to certain credits, to the Registrant in accordance with a four Tier, A through D, NOL usage table. NOLs in excess of the allocated 
$3,650,000 may be utilized beginning in 2016, subject to the Registrant's consent, not to be unreasonably withheld, for a payment of 25% of 
the benefit received. 

Ambac Assurance has utilized all of its current post determination date NOLs generated from September 30, 2011 through December 31, 2016
(post determination date NOLs); however, additional post determination date NOLs may be generated in the future.  During this time period, 
Ambac Assurance's cumulative net taxable income was approximately $1,086,124, which utilized all of the $479,000 allocated Tier A NOL 
and $607,124 of the $1,057,000 allocated Tier B NOL and resulted in accrued Tolling Payments, net of applicable credits.  At December 31, 
2016, $28,691 of Tolling Payments are due to Ambac no later than forty-five days after April 15, 2017 (subject to review by the Rehabilitator).  
Of the bankruptcy related credits available to offset the first $5,000 of payments due under each of the NOL usage Tiers A, B, and C, Ambac 
Assurance has fully utilized the combined $10,000 of Tier A and Tier B credits.

Appendix A

Non-GAAP Financial Measures

Ambac reports two non-GAAP financial measures: Adjusted Earnings and Adjusted Book Value. The most directly comparable GAAP measures are net income 
attributable to common stockholders for Adjusted earnings and Total Ambac Financial Group, Inc. stockholders’ equity for Adjusted Book value.  A non-GAAP 
financial measure is a numerical measure of financial performance or financial position that excludes (or includes) amounts that are included in (or excluded 
from) the most directly comparable measure calculated and presented in accordance with GAAP. We are presenting these non-GAAP financial measures because 
they provide greater transparency and enhanced visibility into the underlying drivers of our business and the impact of certain items that the Company believes 
will reverse from GAAP book value over time through the GAAP statements of comprehensive income. Adjusted Earnings and Adjusted Book Value are not 
substitutes for the Company’s GAAP reporting, should not be viewed in isolation and may differ from similar reporting provided by other companies, which 
may define non-GAAP measures differently.  Each of the reconciling items is more fully defined in our 2016 Annual Report on Form 10-K within Management's 
Discussion and Analysis of Financial Condition and Results of Operations under the heading “Non-GAAP Financial Measures."

Ambac has a significant U.S. tax net operating loss (“NOL”) that is offset by a full valuation allowance in the GAAP consolidated financial statements. As a 
result of this and other considerations, for purposes of non-GAAP measures, we utilized a 0% effective tax rate; which is subject to change. 

In response to a recent comment letter received from the Division of Corporation Finance of the Securities and Exchange Commission, Ambac has implemented 
changes to its non-GAAP measures effective December 31, 2016:  Ambac has changed the name of its non-GAAP measure “Operating Earnings” to “Adjusted 
Earnings”.  Ambac no longer eliminates the effects of VIEs in the calculation of its non-GAAP measures for Adjusted Earnings and Adjusted Book Value.  

For comparative purposes, prior period amounts have been recast in the non-GAAP reconciliation tables shown below to conform to the new presentation.  For 
further information regarding how our non-GAAP measures were reported prior to December 31, 2016 please refer to our September 30, 2016 Form 10-Q and 
previous Form 10-Q and Form 10-K filings.

(1)  Elimination of the foreign exchange gains (losses) on the re-measurement of assets, liabilities and transactions in non-functional currencies.  For periods 
prior to 2016, we eliminated the foreign exchange gains (losses) on the re-measurement of net premium receivables and loss and loss expense reserves in 
non-functional currencies.  Given the long-duration of a significant portion of these premium receivables and loss reserves, the foreign exchange re-
measurement gains (losses) are not necessarily indicative of the total foreign exchange gains (losses) that Ambac will ultimately recognize. Beginning in 
2016,  we  have  eliminated  the  foreign  exchange  gains  (losses)  on  all  assets,  liabilities  and  transactions  in  non-functional  currencies.  Expanding  this 
adjustment to include all foreign exchange gains (losses) enables users of our financial statements to better view the business results without the impact 
of fluctuations in foreign currency exchange rates, particularly as assets held in non-functional currencies have grown, and facilitates period-to-period 
comparisons of Ambac's operating performance. Note that we have not recast prior period adjustments to conform to the methodology as such amounts 
were not material.

(2)  Totals may not add due to rounding differences.
