DEAR FELLOW SHAREHOLDERS

“ 2018 was another milestone  
year for Ambac driven by the  
successful execution of our  
key strategic priorities.”

CLAUDE LeBLANC
President and Chief Executive Officer

2018 was another milestone year for Ambac driven by 
the successful execution of our key strategic priorities 
that we outlined last year. Ambac reported full year 
2018 net income of $267 million, net income to common 
shareholders of $186 million or $3.99 per diluted share 
and Adjusted Earnings(1) of $301 million or $6.47 per  
diluted share. Our performance was positively impacted 
by the successful close of a holistic restructuring 
transaction at the beginning of 2018, resulting in  
the exit from rehabilitation of AAC’s Segregated Account 
(the “Segregated Account”). The execution of this 
transaction together with the exit from rehabilitation of 
the Segregated Account was the culmination of several 
years of hard work and created substantial value for our 
shareholders by significantly increasing Book Value and 
Adjusted Book Value. Execution of this transaction also 
provided several material benefits for Ambac including 
the simplification of our capital structure, greater financial 
and strategic flexibility, materially improved financial 
strength at AAC, significant reduction in operating costs 
and a unified corporate governance structure. 

KEY ACCOMPLISHMENTS FOR THE YEAR:

n   Successfully executed a transformational holistic 

restructuring transaction resulting in the Segregated 
Account’s exit from rehabilitation, increasing Book 
Value per share by approximately $7.00 

n    Significantly decreased our insured risk portfolio  

from year-end 2017 by 25% to $46.9 billion

n    Decreased Adversely Classified Credits by 23% to  
$10.9 billion and Watch List Credits by 19% to $9.0 
billion through proactive efforts and runoff 

n   Negotiated and executed a consensual agreement 
which served as the foundation for the COFINA  
Plan of Adjustment which became effective on 
February 12, 2019

n    Executed an Auction Market Preferred Shares  
(“AMPS”) exchange transaction, capturing a  
discount of approximately $250 million to the 
liquidation preference

n    Executed additional headcount and other cost 

reductions which, together with measures implemented 
in late 2017, resulted in a 27% reduction in headcount 
and a lower run-rate for operating expenses 

n    Refined our compensation program to create further 

alignment with shareholders

1

 
 
The completion of the holistic restructuring transaction also allowed us to accelerate other key priorities to create 
and unlock additional material shareholder value, including active de-risking initiatives, ongoing rationalization of our 
capital and liability structures, loss recovery through active litigation management, ongoing review of the effectiveness 
and efficiency of our operating platform and increased focus on future growth initiatives.

  We are extremely pleased with the outcome of this 
transaction and I believe that the resulting enhanced 
flexibility provides us with the opportunity to move to a 
growth trajectory with expanded tools and resources to 
pursue opportunities focused on creating significant  
long-term value for our shareholders.
  During the year we also continued to aggressively 
pursue Ambac’s key business activity, the active risk 
management and stabilization of our insurance platform. 
We took proactive steps to reduce and mitigate 
potential adverse development in our insured portfolio, 
which improves the quality of our Book Value and 
increases the optionality of our platform. Our targeted 

activities included, among other things, the execution of 
commutation transactions, risk transfer via reinsurance 
transactions with multiple counterparties and the 
proactive facilitation of refinancing transactions and 
policy terminations. Our focus included both Adversely 
Classified Credits and Watch List Credits, which represent 
exposures for which there may be heightened potential 
for future adverse development based on qualitative and 
quantitative stress assumptions. 
  Our efforts, together with natural runoff, resulted in a 
25% reduction of the insured portfolio to $46.9 billion net 
par outstanding at December 31, 2018 from $62.7 billion 
at December 31, 2017. In addition, Adversely Classified

Credits decreased 23% or $3.2 billion, to $10.9 billion  
net par outstanding at December 31, 2018 from $14.1 
billion at December 31, 2017, and Watch List Credits 
decreased 19% or $2.1 billion, to $9.0 billion net par 
outstanding at December 31, 2018 from $11.1 billion at 
December 31, 2017. We continue to believe that focusing 
on the long-term stability of our balance sheet and the 
quality of our Book Value are the key drivers of long-term 
value for our shareholders.
  One of the major de-risking initiatives that we pursued 
during 2018 related to the sales and use tax securitization 
debt issued by COFINA, AAC’s largest insured exposure 
to Puerto Rico. In 2018, we were actively involved in 
crafting the terms of a consensual agreement which later 
became the basis of the COFINA Plan of Adjustment.  
The COFINA Plan of Adjustment, which became effective 
on February 12, 2019, provided for the restructuring of 
over $17.6 billion of bonds and addressed 78% of Ambac’s 
total Puerto Rico exposure. 

In connection with the implementation of the  

COFINA Plan of Adjustment, 75% of AAC insured COFINA 
bondholders elected to commute their insurance policies 
in exchange for cash and new COFINA bonds. As a result, 
AAC’s insured COFINA exposure decreased by $5.5 
billion, based on insured net debt service outstanding 
as of December 31, 2018. This is an excellent outcome 
for AAC and we believe the momentum from this debt 
restructuring and our ongoing de-risking strategy will 
help accelerate consensual, favorable outcomes for AAC’s 
remaining insured Puerto Rico-related exposures. With 
COFINA behind us, we will continue to actively progress 
all aspects of our strategy with respect to mitigating 
losses on our other exposures in Puerto Rico.
   During the year we also made significant strides in our 
remaining RMBS litigations. We will continue to actively 
progress our recovery efforts in order to recoup losses 
relating back to the financial crisis.

Structured Finance

  With the added flexibility resulting from the execution 
of the holistic restructuring transaction and the exit 
from rehabilitation of the Segregated Account, we took 
further steps to rationalize our capital structure and 
strengthen our balance sheet, including full redemption 
of RMBS secured borrowings of $74 million and principal 
paydowns of $214 million on the secured notes issued in 
connection with the holistic restructuring transaction. 
  Another major accomplishment in 2018 that further 
streamlined our capital structure was the execution of an 
exchange transaction for AAC’s auction market preferred 
shares. The AMPS exchange transaction successfully 
closed during the latter half of 2018 with participation 
by over 84% of our AMPS holders, resulting in a discount 
capture of approximately $250 million. This transaction 
further delevered our balance sheet and improved 
the quality of Book Value and Adjusted Book Value. 
Additional transaction benefits included added clarity 
with respect to Ambac’s corporate governance structure 
and increased flexibility with respect to future potential 
capital distributions. 
  During the year we also took steps that significantly 
reduced our core operating costs tied to reductions 
in regulatory oversight expenses and relief from costs 
related to the rehabilitation exit transactions. In addition, 
we also made further headcount reductions of 9% this 
year, the savings of which, once realized, will augment 
the benefit from the 19% headcount reduction we made 
last year and provide for additional reductions of run-rate 
compensation costs. We will continue to evaluate and, 
where appropriate, take further steps to reduce operating 
costs and expenses as we focus on long-term growth  
for the company. 

WELL POSITIONED TO DELIVER  
LONG-TERM VALUE

Our continued focus on executing our key strategic 
priorities makes Ambac well-positioned to advance its 
near- and long-term goal to create material long-term 
shareholder value. As we turn our sights towards a longer 
term growth strategy we have taken significant steps to 
improve the effectiveness and risk profile of our operating 
platform, and are also focused on shaping the firm’s  
“One Ambac” vision by fostering a culture of respect, 
inclusion, collaboration and transparency among our 
employees who are vital to what we do. 
  Our goal is to transition to a long-term growth-
oriented strategy where we can leverage our core 
competencies in credit and insurance, as well as 
our resiliency and expertise in managing complex 
transactions, to transform our platform into one that  
we believe will deliver sustainable long-term value to  
our shareholders. 
  We have increased our focus on exploring and, 
where appropriate, pursuing potential new business 
opportunities where we can deploy capital that we 
believe will be accretive and increase shareholder value. 
We have been exploring various types of transactions  
and strategic opportunities in industries that are 
synergistic and adjacent to our current business with  
a targeted focus on credit, asset management and  
fee-based businesses.

Finally, during the year we took additional steps to 
create further alignment with our shareholders through 
the addition of a relative total shareholder return metric 
to our Long Term Incentive Plan that will be applicable 
starting with Ambac’s 2019 plan. We believe that

(1)  Ambac reports two non-GAAP financial measures: Adjusted Earnings (Loss) and Adjusted Book Value. The most directly comparable GAAP measures are net income attributable to common stockholders for Adjusted Earnings (Loss) 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. 
Adjusted Earnings (Loss) 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

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 the Company’s ability to achieve 
value for holders of its securities, whether from Ambac Assurance 
Corporation  ("Ambac  Assurance")  or  from  transactions  or 
opportunities apart from Ambac Assurance; (3) changes in Ambac 
Assurance’s estimated representation and warranty recoveries or 
loss reserves over time; (4) failure to recover claims paid on Puerto 
Rico  exposures  or  incurrence  of  losses  in  amounts  higher  than 
expected; (5) adverse effects on Ambac’s share price resulting from 
future  offerings  of  debt  or  equity  securities  that  rank  senior  to 
Ambac’s common stock; (6) potential of rehabilitation proceedings 
against Ambac Assurance; (7) dilution of current shareholder value 
or  adverse  effects  on  Ambac’s  share  price  resulting  from  the 
issuance of additional shares of common stock; (8) inadequacy of 
reserves established for losses and loss expenses and possibility 
that  changes  in  loss  reserves  may  result  in  further  volatility  of 
earnings or financial results; (9) 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; (10) the Company's inability to realize the expected 
recoveries included in its financial statements; (11)  insufficiency 
or unavailability of collateral to pay secured obligations; (12) credit 
risk throughout the Company’s business, including but not limited 
to  credit  risk  related  to  residential  mortgage-backed  securities, 
student  loan  and  other  asset  securitizations,  public  finance 
obligations (including obligations of the Commonwealth of Puerto 
Rico and its instrumentalities and agencies as well as obligations 
relating to privatized military housing projects) and exposures to 

reinsurers;  (13)  credit  risks  related  to  large  single  risks,  risk 
concentrations  and  correlated  risks;  (14)  the  risk  that  the 
Company’s  risk  management  policies  and  practices  do  not 
anticipate certain risks and/or the magnitude of potential for loss; 
(15)  risks  associated  with  adverse  selection  as  the  Company’s 
insured portfolio runs off; (16) adverse effects on operating results 
or the Company’s financial position resulting from measures taken 
to  reduce  risks  in  its  insured  portfolio;  (17)  disagreements  or 
disputes  with Ambac Assurance's  primary  insurance  regulator; 
(18)  our  inability  to  mitigate  or  remediate  losses,  commute  or 
reduce  insured  exposures  or  achieve  recoveries  or  investment 
objectives, or the failure of any transaction intended to accomplish 
one or more of these objectives to deliver anticipated results; (19) 
the Company’s substantial indebtedness could adversely affect its 
financial  condition  and  operating  flexibility;  (20)  the  Company 
may not be able to obtain financing or raise capital on acceptable 
terms  or  at  all  due  to  its  substantial  indebtedness  and  financial 
condition;  (21)  the  Company  may  not  be  able  to  generate  the 
significant amount of cash needed to service its debt and financial 
obligations, and may not be able to refinance its indebtedness; (22) 
restrictive covenants in agreements and instruments may impair 
the Company’s ability to pursue or achieve its business strategies; 
(23) loss of control rights in transactions for which we provide 
insurance due to a finding that Ambac Assurance has defaulted; 
(24) the Company’s results of operation may be adversely affected 
by  events  or  circumstances  that  result  in  the  accelerated 
amortization  of  the  Company’s  insurance  intangible  asset;  (25)

obligations  as  equity;  (26)  risks  attendant  to  the  change  in 
composition of securities in the Company’s investment portfolio; 
(27) changes in tax law; (28) changes in prevailing interest rates;

relating  to  determinations  of  amounts  of  impairments  taken  on 
investments; (34) the risk of litigation and regulatory inquiries or 
investigations,  and  the  risk  of  adverse  outcomes  in  connection 
therewith,  which  could  have  a  material  adverse  effect  on  the 
Company’s business, operations, financial position, profitability 
or cash flows; (35) actions of stakeholders whose interests are not 
aligned with broader interests of the Company's stockholders; (36) 
the Company’s inability to realize value from Ambac UK or other 
subsidiaries of Ambac Assurance; (37) system security risks; (38) 
market spreads and pricing on interest rate derivatives insured or 
issued by the Company; (39) the risk of volatility in income and 
earnings, including volatility due to the application of fair value 
accounting; (40) changes in accounting principles or practices that 
may  impact  the  Company’s  reported  financial  results;  (41) 
legislative and regulatory developments, including intervention by 
regulatory authorities; (42) the economic impact of “Brexit”; (43) 
operational risks, including with respect to internal processes, risk 
and investment models, systems and employees, and failures in 
services or products provided by third parties; (44) the Company’s 
financial position that may prompt departures of key employees 
and  may  impact  the  Company’s  ability  to  attract  qualified 
executives and employees; (45) fluctuations in foreign currency

PART I

Item 1.  Business

INTRODUCTION

the 
Ambac  Financial  Group,  Inc.  (“Ambac,”  "AFG"  or 
“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 significant net operating loss carry-forwards, of which $3.5 
billion remain at December 31, 2018. 

Management  reviews  financial  information,  allocates  resources 
and measures financial performance on a consolidated basis. As a 
result, the Company has a single reportable segment.

Financial Guarantee Insurance:

Ambac’s provides financial guarantee policies through its principal 
operating  subsidiary,  Ambac  Assurance  Corporation  ("Ambac 
Assurance" or "AAC") and its wholly owned subsidiary Ambac 
Assurance UK Limited (“Ambac UK”), both of which have been 
in runoff since 2008.  Ambac has another wholly-owned subsidiary, 
Everspan Financial Guarantee Corp. (“Everspan”), which has been 
in runoff since its acquisition in 1997.   Insurance policies issued 
provide an unconditional and irrevocable  guarantee which protects 
the holder of a debt obligation against non-payment when due of 
the principal and interest on the obligations guaranteed.  Pursuant 
to such guarantees, Ambac Assurance and its subsidiaries make 
payments if the obligor responsible for making payments fails to 
do so when scheduled.  Revenues from financial guarantees consist 
of:  (i) premiums  earned  from  insurance  contracts,  net  of 
reinsurance, whether received upfront or on an installment basis 
and  (ii) amendment  and  consent  fees.  Expenses  from  financial 
guarantees consist of: (i) loss and commutation payments; (ii) loss-
related  expenses,  including  those  relating  to  the  remediation  of 
problem credits; and (iii) insurance intangible amortization. 

securities 

(including 

Ambac Assurance  and its subsidiaries have been working toward 
reducing  uncertainties  within  their  insured  portfolios  through 
active monitoring of key exposures such as municipal entities with 
stressed  financial  conditions  (including  Puerto  Rico)  and  asset-
residential  mortgage-backed 
backed 
securities  ("RMBS")  and  student 
loan-backed  securities).  
Additionally, Ambac Assurance and its subsidiaries are actively 
prosecuting  legal  claims  (including  RMBS  related  lawsuits), 
managing the regulatory frameworks applicable to the insurance 
entities,  seeking  to  optimize  capital  allocation  in  a  challenging 
environment 
long  duration  obligations,  and 
that 
attempting to retain key employees.

includes 

The deterioration of the financial condition of Ambac Assurance 
and Ambac UK beginning in 2007 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  and  by  regulatory,  legal  and  contractual 
restrictions. It is highly unlikely that Ambac Assurance will be able 
to make dividend payments to Ambac for the foreseeable future. 
Refer 
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. 

"Dividend  Restrictions,

Derivatives:

Interest rate derivative  transactions are executed through Ambac 
Financial Services (“AFS”), a wholly-owned subsidiary of Ambac 
Assurance.  The primary activity of AFS is to  economically hedge 
interest  rate  risk  in  the  financial  guarantee  and  investment 
portfolios.  Accordingly, interest rate derivatives are positioned to 
benefit  from  rising  rates.    Under  agreements  governing  interest 
rate  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 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  collateral  and  margin  posting 
requirements,  previous  termination  payments  and  other  cash 
needs. 

Credit derivative contracts were executed through  Ambac Credit 
Products  LLC  (“ACP”),  a  wholly  owned  subsidiary  of Ambac 
Assurance,  for  which  fees  are  collected  over  the  contract  term. 
Credit  derivative  contract  terms  are  substantially  similar  to 
financial  guarantee  insurance.    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  based  on  the  Segregated Account  Rehabilitation 
Proceedings (as defined below) and related circumstances has been 
enjoined  by  the  Second  Amended  Plan  of  Rehabilitation  (as 
defined below) and orders of the Rehabilitation Court (as defined 
below). See discussion of “Ambac Assurance Liquidity” in Part 
II, Item 7 included in this Form 10-K for further information. 

Ambac derives derivative revenues from  (i)  changes in the fair 
value  of  the  derivatives  portfolio  resulting  from  interest  rate  or 
credit changes and (ii) the value of future contract terminations or 
settlements which may differ from the carrying value of the those 
contracts.

Credit risks relating to interest rate derivative positions primarily 
relate  to  the  default  of  a  counterparty.  Ambac's  interest  rate 
derivatives  generally  consist  of  centrally  cleared  swaps,  US 
treasury futures and some over-the-counter ("OTC") swaps with 
financial  guarantee 
counterparties. 
Counterparty  default  exposure  is  mitigated  through  the  use  of 
industry standard collateral posting agreements or margin posting 
requirements. Cleared swaps, futures and OTC derivatives with 
bank counterparties require margin or collateral to be posted up to 
or in excess of the market value of the interest rate derivatives. 

customers  or  bank

Interest  rate  derivative  contracts  entered  into  with  financial 
guarantee  customers  are  not  subject  to  collateral  posting 
agreements.  Credit  risk  associated  with  customer  derivatives, 
including  credit  derivatives,  is  managed  through  the  risk 
management processes described in the Risk Management Group 
section  below.  In  some  cases,  interest  rate  derivatives  between 
Ambac  and  financial  guarantee  customers  are  placed  through  a 
third  party  financial  intermediary  and  similarly  do  not  require 
collateral posting.

Ambac 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. 

Corporate Strategy:

In  February  2018,  Ambac  achieved  one  of  its  key  strategic 
objectives:  the  exit  from  rehabilitation  of  Ambac  Assurance’s 
Segregated Account  (as  defined  below).   Having  accomplished 
this  milestone,  Ambac  continues  to  pursue  and  prioritize  its 
remaining key strategic priorities, namely:

•  Active  runoff  of  Ambac  Assurance  and  its  subsidiaries 
through  transaction  terminations,  policy  commutations, 
reinsurance, settlements and restructurings, with a focus on 
our  watch  list  credits  and  known  and  potential  future 
adversely classified credits, that we believe will improve our 
risk  profile,  and  maximizing  the  risk-adjusted  return  on 
invested assets;

•  Ongoing  rationalization  of  Ambac's  and  its  subsidiaries' 

capital and liability structures;

•  Loss  recovery  through  active  litigation  management  and 

exercise of contractual and legal rights;

•  Ongoing  review  of  the  effectiveness  and  efficiency  of 

Ambac's operating platform; and

•  Evaluation of opportunities in certain business sectors that 
meet  acceptable  criteria  that  will  generate  long-term 
stockholder value with attractive risk-adjusted returns.

With  respect  to  our  new  business  strategy,  we  have  identified 
certain business sectors adjacent to Ambac's core business in which 
future opportunities will be evaluated.  We have been evaluating 
strategic opportunities in credit, insurance, asset management and 
other financial services that we believe would be synergistic to 
Ambac  and  would  leverage  our  core  competencies.  We  will 
continue to be measured and disciplined in our approach as we 
pursue opportunities to deploy our capital with the goal of creating 
sustainable  long-term  shareholder  value.    Although  we  are 
exploring new business opportunities for Ambac, no assurance can 
be  given  that  we  will  be  able  to  identify  or  execute  a  suitable 
transaction and/or obtain the financial and other resources that may 
be required to finance the acquisition or development of any new 
businesses or assets.  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 remains speculative. 

The  execution  of Ambac’s  strategy  to  increase  the  value  of  its 
investment in Ambac Assurance is subject to the restrictions set 

forth in the Settlement Agreement, dated as of June 7, 2010 (the 
"Settlement Agreement"), by and among Ambac Assurance, ACP, 
Ambac and certain counterparties to credit default swaps with ACP 
that  were  guaranteed  by  Ambac  Assurance,  as  well  as  the 
Stipulation  and  Order  (as  defined  in  Note  1.  Background  and 
Business  Description  to  the  Consolidated  Financial  Statements 
included in Part II, Item 8 of this Form 10-K) and in the indenture 
for the Tier 2 Notes (as defined in Note 1. Background and Business 
Description to the Consolidated Financial Statements included in 
Part II, Item 8 of this Form 10-K), each of which requires OCI (as 
defined below) and, under certain circumstances, holders of  the 
debt  instruments  benefiting  from  such  restrictions,  to  approve 
certain  actions  taken  by  or  in  respect  of Ambac Assurance.    In 
exercising  its  approval  rights,  OCI  will  act  for  the  benefit  of 
policyholders,  and  will  not  take  into  account  the  interests  of 
Ambac.  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. 

Opportunities for remediating losses on poorly performing insured 
transactions  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.

Segregated Account

In March 2010, Ambac Assurance established a segregated account 
pursuant 
to  Wisconsin  Stat.  §611.24(2)  (the  “Segregated 
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 Everspan 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, itself, did not enter 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.

On  September  25,  2017  the  Rehabilitator  filed  a  motion  in  the 
Rehabilitation  Court  seeking  entry  of  an  order  approving  an 
amendment  to  the  Segregated Account  Rehabilitation  Plan  (the 
"Second  Amended  Plan  of  Rehabilitation").    Following  the 
conclusion of a Confirmation Hearing on January 22, 2018, the 
Rehabilitation Court entered an order granting the Rehabilitator's 
motion  and  confirming 
the  Second  Amended  Plan  of 
Rehabilitation. On February 12, 2018 (the "Effective Date"), the 

| Ambac Financial Group, Inc.   3   2018 FORM 10-K |

Second  Amended  Plan  of  Rehabilitation  became  effective.  
Consequently, the rehabilitation of the Segregated Account was 
concluded. 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.

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  of  Directors  take  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 periodically 
reviews the Company's business plan, factoring risk management 
into  account.  It  also  approves  the  Company's  risk  appetite 
statements, which articulate the Company's tolerance for certain 
risks  and  describes  the  general  types  of  risk  that  the  Company 
accepts, within certain parameters, 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,  Ambac's  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  (particularly  executive  talent) 
compensation structures that might lead to undue risk taking, 
and disclosure of our executive compensation philosophies, 
strategies and activities.

•  The  Governance  and  Nominating  Committee  oversees  the 
management  of  risk  primarily  associated  with  Ambac’s 
ability  to  attract  and  retain  quality  directors,  Ambac’s 
corporate  governance  programs  and  practices  and  our 
compliance  therewith.  Additionally,  the  Governance  and 
Nominating Committee oversees the processes for evaluation 
of  the  performance  of  the  Board  of  Directors  and  its 
committees  each  year  and  considers  risk  management 
effectiveness as part of its 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 of Directors also receive 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  process  that  involves  the  Board  of  Directors, 
management and other personnel in an integrated effort to identify, 
assess and manage a broad range of risks (e.g., credit, financial, 
legal,  liquidity,  market,  model,  operational,  regulatory  and 
strategic), that may affect the Company’s ability to execute on its 
corporate strategy and fulfill its business objectives. The Enterprise 
Risk Committee (“ERC”), which is a management committee, 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.   

Ambac management has established other committees to assist in 
managing the risks embedded in the enterprise.  These committees 
will meet monthly or as needed on an ad hoc basis.  

•  The  Asset  Liability  Management  Committee's  (“ALCO”) 
objective is to foster an enterprise wide culture and approach 
to liquidity management, asset management, asset valuation 
and hedging.  Members of ALCO include the Chief Executive 
Officer, Chief  Financial Officer and senior managers from 
investment management and the Risk Management Group. 

•  The  Risk  Committee's  objective 

is 

to  establish  an 
interdisciplinary team of professionals from different parts of 
the company to provide oversight of the key risk remediation 
issues impacting Ambac.  The purview of the committee is to 
review  and  approve  risk  remediation  activities  for  the 
financial  guarantee  insured  portfolio  as  well  as  review 
changes to Ambac Assurance's adversely classified, survey 
and  watch  list  credits  (as  defined  in  Note  2.  Basis  of 
Presentation 
and  Significant  Accounting  Policies).  
Additionally, the Risk Committee will provide oversight and 
review  new  risk  remediation  structures  or  approaches  in 
connection  with  risk  remediation  plans  or  anticipated 
transactions. This  committee  was  established  in  the  fourth 
quarter of 2017.  Previously, most risk remediation activities 
were approved by ALCO.  Members of the Risk Committee  
include 
the  Chief  Executive  Officer,  Head  of  Risk 
Management, Chief Financial Officer and senior managers 
from 
throughout  risk,  corporate  services,  operations, 
investment management, legal and finance. 

•  The Disclosure Committee's objective is to assist the CEO 
and CFO in their responsibilities to design, establish, maintain 
and  evaluate  the  effectiveness  of  disclosure  controls  and 
procedures.

RISK MANAGEMENT GROUP

Financial guarantee insurance was sold in three principal markets: 
U.S.  public  finance,  U.S.  structured  finance  and  international 
finance.  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.  Please 
refer to Item 7 “Management’s Discussion and Analysis of Financial 
Condition  and  Results  of  Operations  -  Financial  Guarantees  in 
Force” section below for details on the financial guarantee insured 
portfolio.

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). Our ability to 
execute certain risk management activities may be limited by the  
restrictions set forth in the Settlement Agreement, the Stipulation 
and  Order  and  the  indenture  for  the  Tier  2  Notes.    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. 

Ambac’s Risk Management Group ("RMG") has an organizational 
structure designed around four primary areas of focus: Surveillance, 
Risk Remediation, Credit Risk Management and Loss Reserving 
and Analytics. 

Surveillance 

This group's focus is on the early identification of potential stress 
or deterioration in connection with exposures in the insured portfolio 
and  the  related  credit  analysis  associated  with  these  and  other 
insured portfolio exposures.  Additionally, surveillance will evaluate 
the  impact  of  changes  in  the  economic,  regulatory  or  political 
environment on the insured portfolio.

Analysts in this group perform periodic credit reviews of insured 
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.  Active  surveillance  enables 
analysts  to  track  single  credit  migration  and  industry  credit  and 
performance trends. 

The focus of a credit 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.    Please  refer  to  Note  2.  Basis  of 
Presentation  and  Significant  Accounting  Policies 
the 
Consolidated Financial Statements included in Part II, Item 8 in this 
Form 10-K for further discussion of the various credit classifications 
utilized by Ambac.  If a problem is detected, the Surveillance group 
will then work with the Risk Remediation group on a loss mitigation 
plan, as necessary. 

to 

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  reviews  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.  Surveillance 
analysts  review  these  reports  to  monitor  performance  and,  if 
necessary, seek legal advice to ensure that reporting and application 
of cash flows comply with transaction requirements. 

Risk Remediation

This  group’s  focus  is  on  risk  remediation,  loss  mitigation  and 
restructuring related to the insured portfolio of Ambac Assurance. 

Risk  remediation  helps  to  reduce  exposure  to  credits  that  have 
current  negative  developing  trends,  have  the  potential  for  future 
adverse development or are already adversely classified by, among 
other things, securing rights and remedies, both of which may help 
to mitigate losses in the event of further deterioration or event of 
default, or, as available, working with an issuer to refinance or retire 
debt.

Loss  mitigation  focuses  on  the  analysis,  implementation  and 
execution  of  commutation  and  related  claims  reduction  or 
defeasance strategies for policies with potential future claims. Loss 
mitigation prioritizes policies, or portions thereof, for commutation, 
refinancing or other claims reduction or defeasance strategies.

Restructuring or workout is the focused and active process of trying 
to minimize claims and maximize  recoveries, typically following 
an event of default. 

The emphasis on reducing risk is centered on reducing enterprise-
wide exposure on a prioritized basis. 

For certain adversely classified, survey list  and watch list credits, 
Risk  Remediation  analysts  will  develop  and  implement  a 
remediation or loss mitigation plan that could include actions such 
as  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.  Other 
actions  could  include  working  with  bond  holders  and  other 

| Ambac Financial Group, Inc.   5   2018 FORM 10-K |

economic stakeholders to negotiate, structure and execute solutions, 
such as commutations. 

Adversely classified, survey list and watch list credits are tracked 
closely by Surveillance analysts  together with Risk Remediation 
analysts as part of the Risk Remediation  process and are discussed 
at regularly scheduled meetings with Credit Risk Management (see 
discussion following in “Credit Risk Management”) and the Risk 
Committee  (see  discussion  following  in  "Risk  Committee").    In 
some cases, Risk Remediation 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 Risk Remediation, we  have established cross-functional teams 
in key areas of focus, comprised of personnel both within the RMG 
and  in  other  departments,  to  target  proactive  mitigation  and 
remediation  of  losses  and  potential  future  losses  associated  with 
certain credits and sectors in the insured portfolio. Examples of such 
efforts include teams of professionals focused on (i) the review and 
enforcement  of  contractual  representations  and  warranties  
("R&W")  supporting  RMBS  policies,  (ii) RMBS  servicing  and 
remediation and (iii) the analysis and prioritization of policies with 
projected  claims  or  the  potential  for  future  material  adverse 
development to target and execute risk reduction, restructuring and 
commutation strategies. Members of these cross-functional teams 
will often work with external experts in the pursuit of risk reduction 
efforts. 

For  RMBS  insured  exposures,  the  team  focuses  on  servicer 
oversight  and  transaction  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.  In addition, the team actively works 
with servicers and other RMBS transaction sponsors to facilitate the 
exercise  of  clean-up  calls  and  other  risk  and  exposure  reducing 
transactions, sometimes with Ambac Assurance financial support.   

Ambac Assurance believes that the close monitoring of servicers, 
including  measures  to  better  align  the  interests,  and  other  loss 
mitigation activities, 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  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  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 further discussion on this topic). 

Credit Risk Management ("CRM")

CRM  manages  the  decision  process  for  all  material  matters  that 
affect  credit  exposures  within  the  insured  portfolio.  While  not 
responsible for the credit analysis or execution of risk remediation 
or loss mitigation strategies, CRM provides a forum for independent 

assessments,  reviews  and  approvals  and  drives  consistency  and 
timeliness. The scope of credit matters under the purview of CRM 
includes material amendments, waivers and consents, evaluation of 
remediation or loss mitigation plans, credit review scheduling, credit 
classifications, rating designations, review of watch list or adversely 
classified credits, sector reviews and overall portfolio reviews. 

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.  In particular, formal  plans or transactions that relate 
to risk remediation, loss mitigation or restructuring may also require 
Risk Committee approval. In addition, such plans or transactions 
that  have  material  asset  liquidity  implications  may  also  require 
ALCO approval.

Control Rights

In  structured  transactions,  including  certain  structured  public 
finance transactions, Ambac Assurance may be the control party as 
a result of insuring the transaction’s senior class or tranche of debt 
obligations. 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”).   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. Pursuant to the Second Amended 
Plan of Rehabilitation and orders of the Rehabilitation Court, such 
protections continue after the conclusion of the Segregated Account 
Rehabilitation Proceedings.

Watch List Credits

Credits that demonstrate the potential for long-term material adverse 
development, represent significant size or sector concentration, or 
have  certain  structural,  credit  or  other  complexities,  but  are 
otherwise currently performing, may be designated as a watch list 
credit  as  part  of  the  CRM  process. Watch  list  credits  are  closely 
monitored by the Surveillance for potential adverse development 
and  are  targets  for  proactive  risk  reduction  efforts  by  the  Risk 
Remediation group. 

Adversely Classified Credits 

Credits that are either in default or have developed problems that 
eventually  may  lead  to  a  default  are  tracked  closely  by  the 
appropriate Surveillance and Risk Remediation teams and discussed 
at meetings with CRM.  Adversely classified credit meetings include 
members  of  CRM,  Surveillance,  Risk  Remediation  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 

| Ambac Financial Group, Inc.   6   2018 FORM 10-K |

and  proper  internal  and  external  resourcing.  A  summary  of 
developments  regarding  adversely  classified  credits  and  credit 
trends  is  also  provided  to  the  Risk  Committee  and Ambac’s  and 
Ambac Assurance’s Board of Directors no less than quarterly.

The insured portfolio contains exposures that are correlated and/or 
concentrated.  Risk  Management's  surveillance  activities  include 
identifying these types of exposures and identifying the risks that 
would  or  could  trigger  credit  deterioration  across  these  related 
exposures.  When  such  risks  materialize,  an  adverse  credit 
classification  may  be  designated  across  these  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, the impact of tax reform on state and municipal bond 
issuers, 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' Surveillance 
group review, analyze and process all requests for AWCs. All AWCs 
are initially screened for materiality in the Surveillance group. Non-
material AWCs  require  the  approval  of  at  least  the  Surveillance 
analyst and the Surveillance 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 ("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  works  with  Surveillance  and  Risk 
Remediation  analysts  responsible  for  a  particular  credit  on  the 
development, review and implementation of loss reserve scenarios 
and related analysis.

INSURANCE REGULATORY MATTERS AND 
OTHER RESTRICTIONS

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. 
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 regulatory restrictions. 

In addition, pursuant to the terms of the Settlement Agreement, the 
Stipulation and Order and the indenture for the Tier 2 Notes, Ambac 
Assurance must seek prior approval by OCI of certain corporate 
actions.  The  Settlement Agreement,  Stipulation  and  Order  and 
indenture for the Tier 2 Notes include covenants which restrict the 
operations of Ambac Assurance. The Settlement Agreement will 
remain in force until the surplus notes issued thereunder have been 
redeemed, repurchased or repaid in full. The Stipulation and Order 
will remain in force for so long as OCI determines it to be necessary. 
The indenture for the Tier 2 Notes will remain in force until the 
Tier 2 Notes have been redeemed, repurchased or repaid in full. 
Certain  of  the  restrictions  in  the  Settlement  Agreement    and 
indenture for the Tier 2 Notes may be waived with the approval of 
the OCI and/or the requisite percentage of holders of debt securities 
issued thereunder. 

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 
additional 
those  other  EU 
jurisdictions.  See Item 1A. Risk Factors in Part I, Item 1A and
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 regulatory restrictions.

in 

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 

| Ambac Financial Group, Inc.   7   2018 FORM 10-K |

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. 

Common Stock Restrictions

Ambac’s Amended and Restated Certificate of Incorporation limits 
the 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.

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  2019  without 
certain approvals, including the prior consent of the OCI, which 
is unlikely. Ambac Assurance’s ability to pay dividends is further 
restricted by the Settlement Agreement, the Stipulation and Order, 
the  indenture  for  the Tier  2  Notes  and  the  terms  of  its Auction 
Market  Preferred  Shares  ("AMPS").  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. 

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

Pursuant to the Settlement Agreement and the indenture for the 
Tier  2  Notes, 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 Ambac Assurance's surplus notes 
(other than junior surplus notes) would also need to be redeemed 
at par. Any such payment on surplus notes would require either 
payment or collateralization of a proportional amount of the Tier 

2 Notes (or interest thereon) in accordance with the terms of the 
Tier 2 Note indenture.  

The Stipulation and Order requires OCI approval for the payment 
of any dividend or distribution on the common stock of Ambac 
Assurance.

Under the terms of Ambac Assurance’s 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.

INVESTMENTS AND INVESTMENT POLICY

As of December 31, 2018, the consolidated non-VIE investments 
of Ambac had an aggregate fair value of approximately $3.9 billion. 
Investments are  managed both 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's Board of Directors or the Board 
of  Directors  of  the  applicable  subsidiary.    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,  2018,  the Ambac Assurance  and  Everspan 
non-VIE  investment  portfolio  had  an  aggregate  fair  value  of 
approximately  $2.9  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  the  types  and  quality  of  investments  imposed  by 
applicable insurance laws and regulations, which may be waived 
by  the  applicable  regulatory  authority  in  certain  instances. The 
Board of Directors of Ambac Assurance approves any changes to 
Ambac  Assurance's  investment  policy.

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 
holder claims. Ambac UK purchases Ambac UK insured securities 
given  their  relative  risk/reward  characteristics.  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, 2018, the non-VIE Ambac (parent company 
only)  investment  portfolio  had  an  aggregate  fair  value  of 
approximately $0.3 billion. The primary investment objective is 
to preserve capital for strategic uses while maximizing income.  
The  investment  portfolio  is  subject  to  internal  investment 
guidelines.    Such  guidelines  set  forth  minimum  credit  rating 
requirements and credit risk concentration limits.  Ambac invests 
in  securities  insured  or  issued  by Ambac Assurance,  including

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 principal business is in run-off and faces significant risks 
and  uncertainties  described  elsewhere  in  Part  I,  Item  1A.  Risk 
Factors. 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, particularly with regards to concentrations of credit 
risk, such as in Puerto Rico;

•  actual  or  perceived  adverse  developments  with  regards  to 

Ambac Assurance's RMBS litigations; 

•  changes to regulatory status;

•  changes in investors’ or analysts’ valuation measures for our 

stock;

•  market trends unrelated to our stock;

| Ambac Financial Group, Inc.   9   2018 FORM 10-K |

•  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.

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 insured portfolio or significant 
losses or other events resulting from litigation, including the failure 
to achieve expected recoveries from existing litigations concerning 
insured  residential  mortgage-backed  securities  ("RMBS"),  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.

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  any  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 additional shares of Ambac, including shares of 
Ambac  common  stock  underlying  issued  and  outstanding 
warrants, may dilute current shareholder value or have adverse 
effects on the market price of Ambac’s common stock.

If Ambac issues additional shares of common stock to raise capital, 
whether  for  select  business  transactions,  general  corporate 
purposes, in exchange for other securities, or in connection with 
the exercise of issued and outstanding warrants, the value of current 
stockholders’ 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.

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

The value of Ambac's 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 
intercompany tax sharing agreement (the "Amended TSA") and 

the intercompany expense sharing and cost allocation agreement 
(the "Cost Allocation Agreement"); the receipt of payments on the 
Owner Trust  Certificate  issued  to Ambac  by  Corolla Trust  (the 
"Owner Trust Certificate"), which was created in 2014 to monetize 
Ambac's ownership interest in junior surplus notes issued by the 
Segregated Account; the receipt of payments on investments made 
in securities issued or insured by Ambac Assurance; the receipt of 
dividends from Ambac Assurance; and the receipt of payments on 
other investments. There can be no assurance that Ambac will be 
able to realize residual value in Ambac Assurance, which is in run-
off.  There is a risk that Ambac Assurance will not be able to satisfy 
all of its obligations to policyholders, holders of its indebtedness 
(including surplus notes, junior surplus notes, the Ambac Note and 
the Tier 2 Notes) and holders of its preferred stock, even if Ambac 
Assurance  is  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.

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 intercompany 
Cost Allocation Agreement are subject to contingencies that are 
difficult  to  predict  and,  in  certain  instances,  to  OCI  approval, 
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 OCI and limited to $4.0 
million per annum.  We can provide no assurance as to whether 
OCI 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 plus interest thereon.  Such notes and 
the Owner Trust Certificate are collateralized by and payable solely 
from a $350.0 million face amount junior surplus note plus interest 
thereon. Ambac Assurance  became the  obligor under  the junior 
surplus  notes  on  February  12,  2018  pursuant  to  the  Second 
Amended  Plan  of  Rehabilitation.  No  payment  of  interest  on  or 
principal of a junior surplus note may be made until all existing 
and future indebtedness of Ambac Assurance, including (but not 
limited to) senior ranking surplus notes, policy claims and claims 
having statutory priority, have been paid in full. All payments of 
principal and interest on junior surplus notes are subject to the prior 
approval of OCI. If OCI does not approve the payment of interest 
on 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 made when and to the extent that 
Ambac Assurance 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 

| Ambac Financial Group, Inc.   10   2018 FORM 10-K |

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 or 
pari-passu 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 or pari-passu 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.

Risks Related to Insured Portfolio Losses

Loss reserves may not be adequate to cover potential losses, and 
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  adversely  classified.  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/or  restructurings,  and  estimated 
remediation  recoveries  for,  among  other  things,  breaches  by 
RMBS issuers of representations and warranties. 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  (on  a 
probability weighted basis) reflecting the significant uncertainty 
regarding  future  developments  and  outcomes,  our  loss  reserves 
may change materially based on future developments. As a result 
of 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.

transaction  documents,  Ambac  Assurance  or 

Additionally,  inherent  in  our  estimates  of  loss  severities  and 
remediation recoveries is the assumption that Ambac Assurance 
or its subsidiaries, as applicable, will retain control rights in respect 
of  our  insured  portfolio.  However,  according  to  the  terms  of 
relevant 
its 
subsidiaries, as applicable, may lose control rights in many insured 
transactions  if,  among  other  things,  the  relevant  insurer  is  the 
subject  of  delinquency  proceedings  and/or  other  regulatory 
actions. If Ambac Assurance or its subsidiaries lose control rights, 
their  ability  to  mitigate  loss  severities  and  realize  remediation 
recoveries will be compromised, and actual ultimate losses in the 
insured portfolio could exceed current loss reserves.  The Second 
Amended Plan of Rehabilitation of the Segregated Account and 
related orders of the Rehabilitation Court seek to restrain actions 
adverse to Ambac Assurance based on a loss of control rights due 
to the rehabilitation of the Segregated Account or related events 
or circumstances. If the Second Amended Plan of Rehabilitation 
and such orders do not successfully preclude such actions, Ambac 
Assurance  could  lose  its  control  rights  with  respect  to  certain 
policies.

Some  issuers  of  public  finance  obligations  insured  by Ambac 
Assurance  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.

Some  issuers  of  public  finance  obligations  insured  by Ambac 
Assurance  have  reported,  or  may  report,  budget  shortfalls, 
significantly  underfunded  pensions  or  other  fiscal  stresses  that 
imperil  their  ability  to  pay  debt  service  or  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  insured  by Ambac 
Assurance have declared a payment moratorium, defaulted or filed 
for  bankruptcy  or  similar  debt  adjustment  proceedings,  raising 
concerns about their ultimate ability to service the debt insured by 
Ambac Assurance and Ambac Assurance's ability to recover claims 
paid in the future. If the issuers of the obligations in the 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 or for similar relief under other laws 
that  allow  for  the  adjustment  of  debts, Ambac Assurance  may 
experience  liquidity  claims  and/or  ultimate  losses  on  those 
obligations, which could adversely affect the Company's business, 
financial condition and results of operations.

Catastrophic environmental events, particularly those associated 
with hurricanes, earthquakes, wildfires and drought, that result 
in  loss  of  human  life,  significant  property  damage,  and/or  
material  disruption  of  economic  activity  can  have  a  material 
negative  impact on the financial performance of issuers of public 
finance, investor owned utility, privatized military housing and 
other  obligations insured by Ambac Assurance.  Such stresses 
could  result  in  liquidity  claims  or  permanent  losses  on  those 
obligations.

Ambac Assurance insures the obligations of a number of issuers 
that have been substantially affected by environmental events in 
2017 and 2018, including certain municipalities in Texas  as a result 
of  flooding  related  to  Hurricane  Harvey  in  September  2017, 

| Ambac Financial Group, Inc.   11   2018 FORM 10-K |

various obligations of the Commonwealth of Puerto Rico and the 
U.S.  Virgin  Islands  impacted  by  hurricanes  Irma  and  Maria  in 
September and October 2017, certain California issuers affected 
by wildfires in 2017 and 2018, and an issuer in Florida impacted 
by Hurricane Michael in October 2018. 

The  short  and  long  term  impact  of  catastrophic  environmental 
events on issuers and their obligations is by its very nature uncertain 
and is determined by a number of factors including, but not limited 
to, the level of Federal Government support via emergency disaster 
relief  funding  measures,  both  related  to  FEMA  and  otherwise, 
flood insurance, low interest loans, hazard mitigation, the level of 
state government support, the magnitude of commercial insurance 
recoveries, and the outcome of certain socio-economic variables. 
Consequently, if issuers affected by such catastrophic events do 
not receive adequate measures of support or realize the appropriate 
level of economic recovery, it could impact their ultimate ability 
to  service  the  debt  insured  by  Ambac  Assurance  and  Ambac 
Assurance's ability to recover claims paid in the future.

In  addition,  certain  catastrophic  environmental  events,  notably 
wildfires, can result in significant potential liabilities for issuers 
such as investor owned utilities that increase bankruptcy risk and 
the  potential  default  on  obligations  of  the  issuer,  including 
obligations  insured  by Ambac Assurance.  For  example, Ambac 
Assurance  insures  approximately  $32  million  of  obligations  of 
Pacific  Gas  &  Electric  Company,  which  filed  for  bankruptcy 
protection on January 29, 2019, in part due to potentially significant 
liabilities associated with wildfires in 2017 and 2018 in its area of 
operations in California.   

Ambac Assurance insures obligations of the Commonwealth of 
Puerto  Rico,  including  certain  of  its  authorities  and  public 
corporations  that  are  either  subject  to  a  Title  III  bankruptcy 
protection  proceeding  under  the  Puerto  Rico  Oversight, 
Management and Stability Act ("PROMESA") or have otherwise 
suspended debt service payments.  Ambac Assurance has made 
and may continue to 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.   While we believe our reserves are adequate 
to cover losses on Puerto Rico insured bonds, there can be no 
assurance that Ambac Assurance may not incur additional losses 
in  the  future,  particularly  given  the  developing  economic, 
political and legal circumstances in Puerto Rico. Such losses may 
have a material adverse effect on Ambac Assurance's results of 
operation and financial condition.

Ambac Assurance has exposure to the Commonwealth of Puerto 
Rico (the "Commonwealth"), including its authorities and public 
corporations. Each has its own credit risk profile attributable to, 
as applicable, discrete revenue sources, direct general obligation 
pledges and/or general obligation guarantees. Ambac Assurance 
had  approximately  $1.9  billion  of  net  par  exposure  to  the 
Commonwealth and these instrumentalities at December 31, 2018. 
Components of the overall 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 as opposed to 
the current accreted value of the bonds.  The outstanding net insured 
amount  including  accretion  on  capital  appreciation  bonds  is 
approximately $2.6 billion at December 31, 2018.  Total net insured 
lifetime debt service (net par and interest) to the Commonwealth 

of Puerto Rico and its instrumentalities was approximately $9.3 
billion at December 31, 2018. 

As a result of the developments described in these Risk Factors 
and  elsewhere  in  this  10-K  (see  Part  II,  Item  7,  Management's 
Discussion  and Analysis  of  Financial  Condition  and  Results  of 
Operations - Financial Guarantees in Force, and Note 7. Financial 
Guarantee  Insurance  Contracts  to  the  Consolidated  Financial 
Statements  included  in  Part  II,  Item 8  in  this  Form  10-K),  the 
Commonwealth of Puerto Rico and certain of its instrumentalities 
may  continue  to  default  on  debt  service  payments,  including 
payments owed on bonds insured by Ambac Assurance. Ambac 
Assurance has made, and may continue to 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  amount  of  monies  available  for  debt 
service, which is in turn affected by a number of factors including 
variability  in  economic  growth  and  demographic  trends,  tax 
revenues, essential services expense as well as federal funding of 
Commonwealth needs. 

Substantial  uncertainty  also  exists  with  respect  to  the  ultimate 
outcome for creditors in Puerto Rico due to legislation enacted by 
the Commonwealth and the United States, including PROMESA, 
as well as actions taken in reliance on such laws, including Title 
III filings.  Ambac Assurance is involved in multiple litigations 
relating to such actions and other issues and may not be successful 
in pursuing claims or protecting its interests.  Ambac Assurance 
has  been  participating  in  a  mediation  process  with  respect  to 
potential debt restructurings.  Mediation may not be productive or 
may not resolve Ambac Assurance's claims in a manner that avoids 
significant losses.

On February 15, 2019, the United States Court of Appeals for the 
First Circuit issued an opinion in the consolidated appeals brought 
by certain parties who argued that the members of the Financial 
Oversight and Management Board for Puerto Rico (the "Oversight 
Board")  were  appointed  in  violation  of  the  U.S.  Constitution’s 
Appointments Clause. The First Circuit ruled that the Oversight 
Board members (other than the ex-officio Member) must be, and 
were not, appointed in compliance with the Appointments Clause. 
The First Circuit declined to dismiss the Oversight Board’s Title 
III  petitions  and  did  not  render  ineffective  any  otherwise  valid 
actions of the Oversight Board prior to the issuance of the ruling. 
The First Circuit stated that the ruling will not take effect for 90 
days, “so as to allow the President and the Senate to validate the 
currently  defective  appointments  or  reconstitute  the  Board  in 
accordance with the Appointments Clause." During the 90-day stay 
period, the Oversight Board may continue to operate as it had prior 
to the ruling. It is unclear how this ruling, both during the 90-day 
stay period and thereafter, will impact the restructuring process, 
mediation discussions and relevant litigation with respect to our 
Puerto Rico exposures. Certain parties to the litigation may petition 
the U.S. Supreme Court for a writ of certiorari, seeking a review 
of the First Circuit’s decision. 

Given  the  numerous  uncertainties  existing  with  respect  to  the 
restructuring process and relevant litigations, no assurance can be 
given that ultimate debt service discounts will not be severe and 
cause Ambac  to  experience  losses  materially  exceeding  current 
reserves. It is possible that certain restructuring process solutions, 
together  with  associated  legislation,  budgetary,  and/or  public 

| Ambac Financial Group, Inc.   12   2018 FORM 10-K |

policy  proposals  could  be  adopted  and  could  significantly  or 
further impair our exposures. In addition, there are possible final 
legal  determinations,  including  failing  to  recognize  or  properly 
differentiate  legal  structures  and  protections  applicable  to  such 
exposures, that could result in losses exceeding our current reserves 
by a material amount and further increases to our loss reserves. In 
particular, in a Title III process, should court-approved plans of 
adjustment  for  the  Commonwealth,  Puerto  Rico  Highways  and 
Transportation  Authority  ("PRHTA"),  or  any  other  issuers  of 
Ambac-insured debt that file for Title III protection contemplate 
discounts  to  debt  service  implied  by,  or  even  worse  than,  the 
Commonwealth’s  Revised  Fiscal  and  Economic  Growth  Plan 
("Revised FEGP"), the Fiscal Plan Compliance Act be upheld, or 
Ambac receive unfavorable judgments in the litigations to which 
it  is  a  party,  Ambac’s  financial  condition  could  be  materially 
adversely  affected.  It  is  also  possible  that  economic  or 
demographic outcomes may be as, or worse than, forecasted in the 
Commonwealth’s  Revised  FEGP  or  under  proposals  or  plans 
promulgated by the Commonwealth or its instrumentalities in or 
in  connection  with  a  Title  III  process  or  otherwise.  Even  a 
negotiated restructuring to which Ambac agrees as part of a Title 
VI mediation or other process may involve material losses in excess 
of current reserves. While our reserving scenarios reflect a wide 
range of possible outcomes reflecting the significant uncertainty 
regarding future developments and outcomes, given our exposure 
to  Puerto  Rico  and  the  economic,  fiscal,  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.

Implementation of P.L. 115-97, commonly referred to as the Tax 
Cuts and Jobs Act of 2017, may negatively impact the economic 
recovery  of  Puerto  Rico,  which  could  result  in  higher  loss 
severities or an extended moratorium on debt service owed on 
Ambac  Assurance-insured  bonds  of  Puerto  Rico  and  its 
instrumentalities.

The Tax Cuts and Jobs Act effectively treats Puerto Rico the same 
as it does any other foreign tax jurisdiction and otherwise makes 
it  less  attractive  for  U.S.  taxpayers  to  move  certain  operations 
abroad by, among other things, imposing U.S. federal income tax 
on a current basis with respect to certain earnings of controlled 
foreign corporations.  This may diminish the Commonwealth of 
Puerto  Rico’s  relative  attractiveness  as  a  location  for  foreign 
activity  of  a  U.S.  multinational  group,  including  those  with 
manufacturing  facilities  or  other  business  on  the  island.  The 
legislation was implemented in December 2017, at a difficult time 
as  the  Commonwealth  of  Puerto  Rico  was  recovering  from 
Hurricane Maria in October 2017, and, moreover, was amidst a 
multi-year financial crisis that is still ongoing. Consequently, the 
Tax Cuts and Jobs Act could have an adverse impact on the ongoing 
recovery of the Commonwealth of Puerto Rico by impeding much-
needed  economic  growth,  job  growth,  and  revenue  generation, 
which could potentially result in higher loss severities and/or an 
extended  debt  service  moratorium  for  Puerto  Rico  creditors, 
including the Company.

Implementation of the Tax Cuts and Jobs Act of 2017 could have 
a  negative  impact  on  issuers  of  Ambac  Assurance-insured 
municipal bonds.

Under the Tax Cuts and Jobs Act individuals who itemize their 
deductions on their Federal income tax returns will be limited to 
$10,000 of deductions for state and local taxes paid in a given year. 

In  states  with  high  income  tax  rates,  such  as  New  York, 
Connecticut, New Jersey, Maryland, and California, there is a risk 
that  municipal  bond  issuers  could  be  impacted  by  lower  tax 
revenues if there is significant out migration by residents to states 
or municipalities with lower tax rates. Lower tax revenues in these 
jurisdictions  could  lead  to  reduced  financial  flexibility,  lower 
overall  economic  activity  and  increased  credit  risk,  thereby 
potentially  increasing  risk  to Ambac Assurance  with  respect  to 
affected issuers with bonds insured by Ambac Assurance.

the  demand  for  municipal  bond 

In  addition,  the  Tax  Cuts  and  Jobs Act  reduced  the  maximum 
corporate federal income tax rate to 21% from 35%, which could 
reduce 
investments  by 
corporations,  such  as  insurance  companies,  banks,  and  credit 
unions, which currently hold approximately 30% of all outstanding 
municipal bonds.  The impact of reduced demand could result in 
higher  borrowing  costs  for  municipalities  and/or  reduced 
refinancing  flexibility  for  issuers  of  municipal  bonds,  thereby 
potentially  increasing  risk  to Ambac Assurance  with  respect  to 
issuers with municipal bonds insured by Ambac Assurance.

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 the Company's 
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 
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 our 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  and,  specifically,  trusts  with  securities  insured  by 
Ambac  Assurance  have  been  subject  to  heightened  Consumer 
Finance  Protection  Bureau  (CFPB)  scrutiny  and  enforcement 
action over servicing and collections practices and potential chain 
of title issues and, consequently, any settlements, orders, consents 
or penalties resulting from CFPB actions, or any failure on the part 

| Ambac Financial Group, Inc.   13   2018 FORM 10-K |

of  servicers  or  other  parties  asserting  claims  against  delinquent 
borrowers to establish title to the loans, could lead to increased 
losses on securities we insure.

In addition, there can be no assurance that Ambac Assurance would 
be  successful,  or  that  it  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 
the  Company's  results  from  operations  and  on  our  financial 
condition.

One of our primary goals is to create shareholder value through 
transaction  terminations,  policy  commutations,  reinsurance, 
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 
process. 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 and tools to assist our projection of 
performance  of  our  insured  obligations  and  our  investment 
portfolio but actual results could differ materially from the model 
and tool outputs and related analyses.

We rely on internally and externally developed complex financial 
models, including default models related to RMBS and a waterfall 
tool provided by a nationally recognized vendor for RMBS and 
student  loan  exposures,  to  project  performance  of  our  insured 
obligations  and  similar  securities  in  our  investment  portfolio. 
These  models  and  tools  assume  various  conditions,  probability 
scenarios, facts and circumstances, and there can be no assurance 
that  such  models  or  tools  accurately  predict  or  measure  the 
quantum of losses, loss reserves and timing of losses. Differences 
in the models and tools that we employ, uncertainties or flaws in 
these financial models and tools, or faulty assumptions inherent in 
these  financial  models  and  tools  or  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,  estimates  of 
transaction  performance  depend  in  part  on  the  interpretation  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.

Political  developments  may  materially  adversely  affect  our 
insured portfolio.

Our  insured  exposures  and  our  results  of  operations  can  be 
materially affected by political developments at the federal, state 
and/or  local  government  levels.  Government  shutdowns,  trade 
disputes, political turnover, judicial decisions, adverse changes in 
federal  funding,  or  poor  public  policy  decision  making  could 
disrupt the national and local economies where we have insured 
exposures. In addition, we are exposed to correlation risk as a result 
of  the  possibility  that  multiple  credits  may  concurrently  and/or 
consecutively experience losses or increased stress as a result of 
any such event or series of events.

Risks Related to Indebtedness

Ambac Assurance's ability to generate the significant amount of 
cash needed to service its debt and financial obligations and its 
ability to refinance all or a portion of its indebtedness or obtain 
additional  financing  depends  on  many  factors  beyond  our 
control.

Ambac Assurance is highly leveraged and has greater indebtedness 
outstanding  following  consummation  of  the  Rehabilitation  Exit 
Transactions and the AMPS Exchange.  Ambac Assurance’s ability 
to make payments on and refinance its debt, including surplus notes 
(which continue to accrete based on compounding interest when 
interest has not been paid), and other financial obligations and to 
fund its operations will depend on its ability to generate substantial 
operating  cash  flow  and  on  the  performance  of  the  insured 
portfolio.   Ambac Assurance’s cash flow generation will depend 
on  receipt  of  premiums,  investment  returns,  earnings  from 
subsidiaries  and  potential 
litigation  recoveries  offset  by 
policyholder claims, commutation payments, operating and loss 
adjustment expenses, and interest expense, which will be subject 
to prevailing economic conditions and to financial, business and 
other factors, many of which are beyond our control and many of 
which are event-driven.

As of December 31, 2018, Ambac Assurance had approximately 
$2,198.9 million of  indebtedness outstanding (the Tier 2 Notes 
and the Ambac Note) that are senior to its surplus notes.  Ambac 
Assurance had $573.8 million principal balance of surplus notes 
(other than junior surplus notes) outstanding plus $366.6 million 
principal  balance  of  junior  surplus  notes  outstanding  as  of 
December 31, 2018.  The Tier 2 Notes and the Ambac Note are 
secured by potential litigation recoveries (and in the case of the 
Ambac Note, other assets), the receipt of which is highly uncertain, 
as more fully discussed in Part I, Item 1A. Risk Factors.  Failure 
to achieve litigation recoveries in an amount sufficient to repay the 
Tier 2 Notes and the Ambac Note would materially weaken Ambac 
Assurance’s ability to service its indebtedness.

If Ambac Assurance cannot pay its policyholders’ claims or service 
its  debt,  it  will  have  to  take  actions  such  as  selling  assets, 
restructuring or refinancing its debt or seeking additional capital.  
Any  of  these  remedies  may  not,  if  necessary,  be  effected  on 
commercially reasonable terms, or at all.  Because of these and 

| Ambac Financial Group, Inc.   14   2018 FORM 10-K |

other factors beyond our control, Ambac Assurance may be unable 
to pay the principal, interest or other amounts on its indebtedness 
when due or ever.

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

Our substantial indebtedness could have significant consequences 
for our financial condition and operational flexibility.  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 claims, debt service requirements, acquisitions, 
general corporate purposes or other purposes on satisfactory 
terms or at all;

•  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 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.

Despite current indebtedness levels, we 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,  its  ability  to  make  scheduled 
payments on, or refinance, any such indebtedness may depend on 
the  ability  of  our  subsidiaries  to  make  distributions  or  pay 
dividends,  which  in  turn  will  depend  on  their  future  operating 
performance and contractual, 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 Secured Notes and Tier 2 Notes are primarily secured by 
potential  recoveries  on Ambac Assurance’s  RMBS  litigations, 
and Ambac Assurance’s ability to obtain, and the timing of, any 
recovery  on  the  RMBS  litigations  is  subject  to  significant 
uncertainty.

The  Secured  Notes  and  Tier  2  Notes  are  primarily  secured  by 
Ambac  Assurance’s  potential  recoveries  in  respect  of  RMBS 
litigations. Ambac Assurance's  ability  to  obtain  such  recoveries 
and  the  timing  of  receipt  of  any  such  recoveries  are  subject  to 
significant  risks  and  uncertainty,  as  described  below  in  Risks 
Related to Capital, Liquidity and Markets.

In addition, while a policy issued by Ambac Assurance guarantees 
all  principal  and 
interest  payments  (including  mandatory 
prepayments) in respect of the Secured Notes as and when such 

payments become due and owing, such policy may not provide 
adequate  assurance  that  payments  of  principal  and  interest  in 
respect of the Secured Notes will be available in the event that 
Ambac Assurance’s financial condition, including its capital and 
liquidity, is materially adversely affected, including as a result of 
the failure to recover expected damages and, as a result, Ambac 
Assurance is unable to satisfy its policy obligations. In the event 
that Ambac Assurance is unable to satisfy its obligations under the 
Secured Notes policy, holders of the Secured Notes will have the 
right to foreclose on the securities constituting collateral for the 
Secured Notes and to sue Ambac Assurance for failure to make 
payments under the Secured Notes policy; however, there can be 
no assurance that the sale of the securities collateral will produce 
proceeds in an amount sufficient to pay any or all amounts due on 
the Secured Notes or that holders will be successful in any litigation 
seeking  payments  pursuant  to  the  Secured  Notes  policy. 
Furthermore, holders of Secured Notes will not obtain any control, 
consultation or direction rights in respect of the RMBS litigations 
nor  will  holders  be  able  to  sell  the Ambac  Note  or  the  right  to 
receive proceeds in respect of the RMBS litigations without the 
prior consent of Ambac Assurance. 

Holders of Secured Notes and Tier 2 Notes will have no authority 
to make decisions in respect of the RMBS litigations, will need 
to rely on Ambac Assurance to pursue the RMBS litigations and 
may  only  receive  limited  information  concerning  the  RMBS 
litigations.

All  decisions  concerning  the  conduct  of  the  RMBS  litigations, 
including as to strategy, settlement, pursuit and abandonment, will 
be  made  by  Ambac  Assurance,  in  consultation  with  its  legal 
counsel. Holders of the Secured Notes and Tier 2 Notes will have 
no control over any decisions related to the RMBS litigations and 
will need to rely on Ambac Assurance to prosecute the underlying 
claims. If holders do not agree with decisions by Ambac Assurance 
with respect to the RMBS litigations, there is no recourse or ability 
to object to such decision. Additionally, Ambac Assurance’s ability 
to disclose potentially material details of the RMBS litigations on 
a regular basis may be limited by litigation strategy and the inherent 
nature and rules of judicial proceedings, including, among other 
things, proceedings and filings that are sealed by the court, matters 
involving  attorney-client  privilege  and  proceedings  that  are 
conducted on a confidential basis by agreement of the parties. 

Ambac Assurance may receive non-cash proceeds in respect of 
the RMBS litigations and may need to liquidate such proceeds 
for less than fair market value in order to make cash payments 
on the Ambac Note and/or the Tier 2 Notes.

In connection with a settlement agreement or judgment, Ambac 
Assurance may receive non-cash proceeds or indirect proceeds, 
which are cash or non-cash proceeds received by others for the 
benefit of Ambac Assurance. Ambac Assurance, however, will be 
required to make payments on the Ambac Note, for the benefit of 
the holders of Secured Notes, and on the Tier 2 Notes, in cash. In 
the  event  that  Ambac  Assurance  receives  non-cash  proceeds, 
Ambac Assurance may need to liquidate the non-cash proceeds if 
it does not have sufficient cash available to make a payment on the 
Ambac Note or the Tier 2 Notes on the applicable payment date. 
Market and economic conditions, governmental actions, the form 
of  non-cash  proceeds  and  other  factors  may  cause  substantial 
delays in the ability to liquidate any non-cash proceeds received. 
Ambac  Assurance  may  not  be  able  to  liquidate  any  non-cash 
proceeds received for fair value or at all. If Ambac Assurance is 

| Ambac Financial Group, Inc.   15   2018 FORM 10-K |

unable to liquidate non-cash proceeds at their fair value, Ambac 
Assurance will still be required to make payments on the Ambac 
Note and Tier 2 Notes and any payment made that is greater than 
the amount received could have a material adverse effect on Ambac 
Assurance’s financial condition, including its capital and liquidity. 
If indirect proceeds are received, Ambac Assurance will also be 
required to make payments on the Ambac Note, for the benefit of 
the holders of Secured Notes, and on the Tier 2 Notes, in cash to 
the  extent  of  the  fair  value  to Ambac Assurance  of  the  indirect 
proceeds. Any payments of cash on the Ambac Note and/or the 
Tier 2 Notes as the result of receiving indirect proceeds may have 
a  material  adverse  effect  on  Ambac  Assurance’s  financial 
condition, including its capital and liquidity.

There may not be sufficient collateral to pay any or all of the 
Secured Notes or Tier 2 Notes.

In  addition  to  Ambac  Assurance’s  right  to  representation  and 
warranty ("R&W") recoveries in respect of the RMBS litigations, 
which is inherently uncertain, the Ambac Note is also secured by 
securities having an estimated fair market value of approximately 
$210 million.  However, no appraisal of the value of the securities 
has been made and there can be no assurances that the fair market 
value of these securities will not decrease significantly.  The value 
of the collateral in the event of liquidation will depend on market 
and  economic  conditions,  the  availability  of  buyers  and  other 
factors. Consequently, liquidating the securities collateral securing 
the Ambac Note may not produce proceeds in an amount sufficient 
to pay any or all amounts due on the Secured Notes.

The estimated fair market value of the securities collateral securing 
the Ambac  Note  is  subject  to  fluctuations  based  on  factors  that 
include, among others, the financial condition of participants in 
the  financial  guaranty  insurance  industry,  the  market  for  and 
availability of financial guaranty insurance, the ability to sell the 
collateral  in  an  orderly  sale,  general  economic  conditions,  the 
availability of buyers and other factors.  The amount to be received 
upon  a  sale  of  the  securities  collateral  would  be  dependent  on 
numerous  factors,  including,  but  not  limited  to,  the  actual  fair 
market value of the collateral at such time and the timing and the 
manner of the sale, and the amount Ambac Assurance receives may 
not equal or exceed the expected fair market value.  Accordingly, 
there can be no assurance that the collateral can be sold in a short 
period of time or at all or at acceptable prices to Ambac Assurance. 

In the event of rehabilitation, liquidation, conservation, dissolution 
or other insolvency proceeding, Ambac Assurance cannot assure 
holders  that  the  proceeds  from  any  sale  or  liquidation  of  the 
securities collateral will be sufficient to pay any or all of Ambac 
Assurance’s obligations under the Ambac Note. 

In addition, in the event of any such proceeding, it is possible that 
the rehabilitator, trustee, or competing creditors will assert that the 
value of the collateral with respect to the Ambac Note or the Tier 
2  Notes,  including  Ambac  Assurance’s  rights  to  recoveries  in 
respect  of  the  RMBS  litigations,  is  less  than  the  then-current 
principal  amount  outstanding  under  the  Ambac  Note  and  the 
Secured  Notes  and/or  the  Tier  2  Notes  on  the  date  of  the 
rehabilitation filing. Upon  a finding by the court overseeing an 
Ambac Assurance  rehabilitation  that  the  Ambac  Note  and  the 
Secured Notes and/or the Tier 2 Notes are under-collateralized, the 
claims in the rehabilitation proceeding with respect to the Ambac 
Note, the Secured Notes or the Tier 2 Notes may be bifurcated 

between a secured claim up to the value of the collateral and an 
unsecured claim for any deficiency. As a result, the claim of the 
holders of the Secured Notes or the Tier 2 Notes could be unsecured 
in whole or in part. The ability of the holders of the Secured Notes 
or Tier 2 Notes to realize upon any of the collateral securing the 
Ambac Note and the Secured Notes or Tier 2 Notes, as the case 
may be, may also be subject to bankruptcy and insolvency law 
limitations or similar limitations applicable in insurance company 
rehabilitation or liquidation proceedings.

Rights of holders of the Secured Notes in the RMBS litigations 
and securities collateral and rights of holders of the Tier 2 Notes 
in the RMBS litigations may be adversely affected by the failure 
to  perfect  security  interests  in  such  collateral,  and  insolvency 
considerations with respect to Ambac Assurance may have an 
adverse effect on the ability of holders of the Secured Notes and 
Tier 2 Notes to receive payments on the Secured Notes or Tier 2 
Notes, respectively.

Applicable law provides that a security interest in certain tangible 
and intangible assets can only be properly perfected and its priority 
retained through certain actions undertaken by the secured party. 
There can be no assurance that the collateral agent in respect of 
the Secured Notes or Tier 2 Notes will have taken or will take all 
actions necessary to create properly perfected security interests in 
the proceeds from the RMBS litigations, which may result in the 
loss of the priority of the security interest in favor of the holders 
of the Secured Notes or the Tier 2 Notes, respectively, to which 
they would otherwise have been entitled.  In particular, in the event 
of a rehabilitation, liquidation, conservation, dissolution or other 
insolvency  proceeding  with  respect  to Ambac Assurance,  if  the 
proceeds from the RMBS litigations received by Ambac Assurance 
are  determined  not  to  be  under  the  control  of  the  issuer  of  the 
Secured Notes, a receiver or a creditor of Ambac Assurance may 
take the position that the Secured Notes issuer’s security interest 
in such proceeds or a portion thereof is not perfected and therefore 
that such proceeds do not secure the Ambac Note. With respect to 
the  Tier  2  Notes,  in  the  event  of  a  rehabilitation,  liquidation, 
conservation,  dissolution  or  other  insolvency  proceeding  with 
respect  to Ambac Assurance,  if  the  proceeds  from  the  RMBS 
litigations received by Ambac Assurance are determined not to be 
under  the  control  of  the  collateral  agent for  the Tier  2  Notes,  a 
receiver or a creditor of Ambac Assurance may take the position 
that such collateral agent’s security interest in such proceeds or a 
portion thereof is not perfected and therefore that such proceeds 
do not secure the Tier 2 Notes. Moreover, if the proceeds from the 
RMBS 
initiation  of  a 
rehabilitation,  liquidation,  conservation,  dissolution  or  other 
insolvency  proceeding  with  respect  to  Ambac  Assurance,  a 
receiver or a creditor of Ambac Assurance may take the position 
that such proceeds do not secure the Ambac Note or the Tier 2 
Notes. If a court were to accept either of these positions, payments 
under  the Ambac  Note  or  Tier  2  Notes,  as  applicable,  may  be 
adversely affected and the Secured Notes or Tier 2 Notes, as the 
case may be, may become worthless.  In addition, a rehabilitation, 
liquidation,  conservation,  dissolution  or  other 
insolvency 
proceeding with respect to Ambac Assurance or the issuer of the 
Secured Notes, as applicable, could lead to delays in payments due 
on the Secured Notes or Tier 2 Notes.

Fraudulent transfer laws may permit a court to void the Ambac 
Note, and if that occurs, holders may not receive any payments 
on the Secured Notes. 

Fraudulent  transfer  and  conveyance  statutes  may  apply  to  the 
issuance  of  the Ambac  Note.  Under  state  fraudulent  transfer  or 
conveyance laws, which may vary from state to state, the Ambac 
Note  could  be  voided  as  a  fraudulent  transfer  or  conveyance  if 
Ambac Assurance (a) issued the Ambac Note with the intent to 
hinder,  delay  or  defraud  creditors  or  (b) received  less  than 
reasonably  equivalent  value  or  fair  consideration  in  return  for 
issuing the Ambac Note and, in the case of (b) only, one of the 
following is also true at the time thereof:

•  Ambac Assurance  was  insolvent  or  rendered  insolvent  by 

reason of the issuance of the Ambac Note;

•  the issuance of the Ambac Note left Ambac Assurance with 
an unreasonably small amount of capital or assets to carry on 
its business; or

•  Ambac Assurance intended to, or believed that it would, incur 

debts beyond its ability to pay as they mature.

As a general matter, value is given for a transfer or an obligation 
if, in exchange for the transfer or obligation, property is transferred 
or a valid antecedent debt is satisfied. 

Ambac Assurance  cannot  be  certain  as  to  the  standards  a  court 
would  use  to  determine  whether  or  not Ambac Assurance  was 
insolvent at the relevant time or, regardless of the standard that a 
court uses, whether the Secured Notes would be subordinated to 
Ambac Assurance’s other debt or policyholder claims. In general, 
however, a court would deem an entity insolvent if:

•  the sum of its debts, including contingent and unliquidated 
liabilities, was greater than the fair saleable value of all of its 
assets;

•  the present fair saleable value of its assets was less than the 
amount that would be required to pay its probable liability on 
its  existing  debts,  including  contingent  liabilities,  as  they 
become absolute and mature; or

•  it could not pay its debts as they became due.

If a court were to find that the issuance of the Ambac Note was a 
fraudulent  transfer  or  conveyance,  the  court  could  void  the 
payment obligations under the Ambac Note or could subordinate 
the Ambac Note to presently existing and future indebtedness or 
policy obligations of Ambac Assurance, and, as a result, holders 
may not receive any payments on the Secured Notes. 

Ambac Assurance  has  ongoing  obligations  related  to  surplus 
notes.

Subject to approval by OCI, Ambac Assurance is required to make 
interest  and  principal  (to  the  extent  due)  payments  in  cash  on 
surplus notes on an annual basis. Ambac Assurance will be required 
to continue to make such payments, as and when approved by OCI, 
until  all  of  the  surplus  notes  mature,  are  repaid  in  full  or  are 
otherwise  repurchased  or  retired.    Ambac  Assurance  is  also 
obligated to make payments on junior surplus notes, subject to OCI 
approval, after the senior surplus notes and other indebtedness have 
been paid in full. Ambac Assurance may not have the ability to 
borrow, raise or otherwise have access to the funds necessary to 
pay such amounts when due.

Surplus notes may be acquired, redeemed or repaid on terms that 
may be viewed as more, or less, favorable than the terms of the 
consideration  offered  in  the  exchange  offers  consummated  in 
February 2018 (the "Exchange Offers").

The Company may acquire, redeem or repay surplus notes through 
open  market  purchases,  privately  negotiated  transactions,  other 
tender or exchange offers, redemptions, repayment at maturity or 
such other means as the Company deems appropriate, subject to 
the restrictions in the Settlement Agreement, Stipulation and Order, 
indenture for  the Tier  2  Notes  and  regulatory restrictions.  Any 
such transactions will occur upon the terms and at the prices as the 
Company may determine in its sole discretion, which may be more 
or less favorable than the terms of the Exchange Offers, and could 
be for cash or other consideration.  The Company may choose to 
pursue any or none of these alternatives, or combinations thereof, 
in the future.

Surplus  notes  are  subordinated  in  right  of  payment  to  other 
claims, which could impair the right of the holders of such notes 
to receive interest and principal in the event of our insolvency or 
a similar occurrence.

Surplus notes are unsecured obligations of Ambac Assurance and 
are expressly subordinated in right of payment to all of Ambac 
Assurance’s  existing  and  future  indebtedness  (other  than  junior 
surplus notes) and policy claims.  The surplus notes are subject to 
provisions  of  Wisconsin  insurance  law,  which  establishes  the 
priority of distribution of claims from the estate of an insolvent 
insurance company.  In the event that Ambac Assurance becomes 
subject to rehabilitation, liquidation, conservation or dissolution, 
holders  of  Ambac Assurance’s  senior  indebtedness  and  policy 
claims  would  be  afforded  a  higher  priority  of  distribution  than 
holders of the surplus notes, and accordingly would have the right 
to be paid in full before holders of the surplus notes would be paid.  
Due to the nature of Ambac Assurance’s business, the amount of 
such  higher  priority  claims  in  any  rehabilitation,  liquidation, 
conservation or dissolution is likely to be many times greater than 
any free and divisible surplus and it is likely that the holders of 
surplus  notes  would  not  recover  any  payment 
in  such 
circumstances.  In addition, claims of holders of the surplus notes 
will  be  subordinated  to  certain  liabilities  of  the  Company’s 
subsidiaries that are guaranteed by Ambac Assurance.

Ambac Assurance  has  not  made  regular  interest  or  principal 
payments on surplus notes and may be unable to repay surplus 
notes in full at maturity or ever.

On November 20, 2014, Ambac Assurance, with the approval of 
OCI, redeemed surplus notes (other than junior surplus notes) in 
an amount equal to 26.67% of the principal amount of the surplus 
notes,  plus  accrued  interest  thereon,  outstanding  as  of  July  20, 
2014,  or  approximately  $396  million  owned  by  third  parties.  
However,  except  for  a  one-time  payment  of  approximately  six 
months of interest on the surplus notes (other than junior surplus 
notes) outstanding immediately after the Exchange Offers, no other 
interest  or  principal  payments  on  the  surplus  notes  have  been 
approved or made to date, and Ambac Assurance may not receive 
approval from OCI to make payments as and when scheduled.  As 
a result, holders of surplus notes may not be paid in full at maturity 
or ever.  If OCI does not approve regular payments on the surplus 
notes (other than junior surplus notes) within the next several years, 
the accretion of surplus notes may exceed our ability to ever repay 
in full the surplus notes.  If Ambac Assurance becomes subject to 

| Ambac Financial Group, Inc.   17   2018 FORM 10-K |

a  rehabilitation or liquidation under the Wisconsin insurance law, 
prior to the repayment of surplus notes, holders of surplus notes 
may not receive any recoveries on their investments.

The effects of the amendments to the Settlement Agreement done 
in connection with the Exchange Offers could materially and 
adversely  affect  the  credit  risk  inherent  in,  and  significantly 
reduce protections afforded in, outstanding surplus notes.

Holders of outstanding surplus notes are subject to the terms of the 
Settlement Agreement as modified. Certain restrictive covenants 
and  other  related  provisions  in  the  Settlement  Agreement, 
including covenants regarding mergers and consolidations and the 
incurrence  of  indebtedness,  were  modified  or  eliminated  in 
connection  with  the  Exchange  Offers.  As  a  result,  holders  of 
surplus  notes  are  not  entitled  to  the  benefit  of  such  provisions, 
which  existed  for  the  protection  and  benefit  of  holders  of  the 
surplus notes issued pursuant to the Settlement Agreement. The 
Settlement Agreement,  as  so  amended,  continues  to  govern  the 
terms of all surplus notes issued thereunder that remain outstanding 
after the consummation of the Exchange Offers and Rehabilitation 
Exit Transactions. Accordingly, we may take certain actions in the 
future previously prohibited under the Settlement Agreement that 
could adversely affect the market prices of the surplus notes and 
otherwise increase the risks related to investments in the surplus 
notes.

Increases in interest rates will increase the cost of servicing our 
debt, could reduce our profitability, and could result in a decrease 
in the value of the Secured Notes.

The  Secured  Notes  bear  interest  at  a  variable  rate. As  a  result, 
increases in interest rates will increase the cost of servicing the 
Secured Notes and could adversely affect our profitability and cash 
flows. Each one percentage point increase in interest rates would 
result  in  an  $19.4  million  increase  in  the  annual  cash  interest 
payments due on the Secured Notes.

Changes  in  inter-bank  lending  rate  reporting  practices  or  the 
method  pursuant  to  which  LIBOR  rates  are  determined  may 
adversely affect the value of LIBOR linked financial instruments.

Since February 1, 2014, the administration of LIBOR has been 
undertaken by ICE Benchmark Administration Limited (“IBA”), 
a  subsidiary  of  Intercontinental  Exchange  Group.  IBA,  as  the 
administrator of LIBOR, may make changes in methodology that 
could change the level of LIBOR, which in turn may adversely 
affect  the  value  of  financial  instruments  linked  to  LIBOR, 
including  investment  securities,  swaps,  and  the  Secured  Notes. 
Since 2014, the IBA published multiple papers and other literature, 
including a “LIBOR Code of Conduct” relating to the setting of 
LIBOR.  IBA  has  the  power  to  alter,  discontinue  or  suspend 
calculation or dissemination of LIBOR. 

On July 27, 2017, the U.K. Financial Conduct Authority announced 
that it will no longer persuade or compel banks to submit rates for 
the  calculation  of  LIBOR  rates  after  2021  (the  “July  27th 
Announcement”). The July 27th Announcement indicates that the 
continuation of LIBOR on the current basis cannot and will not be 
guaranteed after 2021. Consequently, at this time, it is not possible 
to predict whether and to what extent banks will continue to provide 
LIBOR submissions to the administrator of LIBOR or whether any 
additional  reforms  to  LIBOR  may  be  enacted  in  the  United 
Kingdom or elsewhere.  Similarly, it is not possible to predict what 
rate or rates may become accepted alternatives to LIBOR or the 

effect  of  any  such  alternatives  on  the  value  of  LIBOR-linked 
securities. Any of the above changes or any other consequential 
changes to LIBOR or any alternative rate or benchmark as a result 
of any international, national, or other proposals for reform or other 
initiatives or investigations, or any further uncertainty in relation 
to the timing and manner of implementation of such changes, could 
have a material adverse effect on the value of investments in our 
investment portfolio, swaps we use for hedging, and the Secured 
Notes.

The amount of interest payable on the Secured Notes is set only 
once per interest period based on the three-month LIBOR rate 
on  the  applicable  interest determination date,  which  rate  may 
fluctuate substantially, and affect our ability to make payment 
on the Secured Notes.

In  the  past,  the  level  of  the  three-month  LIBOR  rate  has 
experienced significant fluctuations. Historical levels, fluctuations 
and  trends  of  the  three-month  LIBOR  rate  are  not  necessarily 
indicative  of  future  levels. Any  historical  upward  or  downward 
trend in the three-month LIBOR rate is not an indication that the 
three-month  LIBOR  rate  is  more  or  less  likely  to  increase  or 
decrease  at  any  time  during  an  interest  period  for  the  Secured 
Notes, and historical levels of the three-month LIBOR rate should 
not be taken as an indication of its future performance. In addition, 
although the actual three-month LIBOR rate on an interest payment 
date or at other times during an interest period may be higher than 
the 
interest 
determination  date,  the  only  relevant  date  for  purposes  of 
determining the interest payable on the Secured Notes is the three-
month LIBOR rate as of the respective interest determination date. 
Changes  in  the  three-month  LIBOR  rates  between  interest 
determination  dates  will  not  affect  the  interest  payable  on  the 
Secured Notes. As a result, changes in the three-month LIBOR rate 
may not result in a comparable change in the market value of the 
Secured Notes.

three-month  LIBOR  rate  on 

the  applicable 

The Secured Notes will bear interest at floating rates that could 
rise significantly, increasing Ambac Assurance’s interest expense 
and reducing its cash flow. If Ambac Assurance’s interest expense 
increases  significantly,  whether  due  to  changes  in  LIBOR  or 
increased  borrowing  costs  when  its  refinances  its  current 
indebtedness, Ambac Assurance may not be able to make payments 
with respect to the Secured Notes or its other indebtedness.

Ambac’s estimated R&W recovery may change over time, causing 
the perceived value of the collateral securing the Secured Notes 
and Tier 2 Notes to change, and any such change may be material.

Ambac reevaluates its estimated R&W recoveries on a quarterly 
basis in connection with the preparation of its financial statements. 
See “Critical Accounting Policies and Estimates” in Part II, Item 
7,  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 
of this Form 10-K for the fiscal year ended December 31, 2018. 
As a result of any reevaluation, the estimated amount of Ambac’s 
R&W  recovery  may  be  adjusted  upward  or  downward  due  to, 
among  other  things,  changes  in  management's  view  of  such 
estimated recoveries and/or changes in the loss reserves related to 
such recoveries, and any adjustment may be material.  Changes in 
estimated  R&W  recoveries  may  result  in  material  changes  in 
Ambac’s financial condition, including its capital and liquidity. In 
addition, any adjustment to estimated R&W recoveries may alter 

| Ambac Financial Group, Inc.   18   2018 FORM 10-K |

the perceived value of the collateral securing the Secured Notes 
and Tier 2 Notes before payment on the Secured Notes or Tier 2 
Notes is made in full, which may affect the value of, and trading 
market, if any, for, the Secured Notes or Tier 2 Notes. Management 
makes no representation that the estimated R&W recoveries will 
not change, materially or at all, including in the near term. There 
can be no assurance that the estimated R&W recoveries securing 
the  Secured  Notes  and  Tier  2  Notes  will  equal  or  exceed  the 
principal  amount  of  the  Secured  Notes  and  Tier  2  Notes, 
respectively, at all times prior to maturity. 

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 and the value of 
our securities, including the Secured Notes and Tier 2 Notes.

Ambac Assurance is pursuing claims in litigation with respect to 
certain RMBS transactions that it insured.  These claims are based 
on,  among  other  things,  representations  with  respect  to  the 
characteristics of the securitized loans, the absence of borrower 
fraud  in  the  underlying  loan  pools  or  other  misconduct  in  the 
origination process, the compliance of loans with the prevailing 
underwriting policies, and compliance of the RMBS transaction 
counterparties  with  policies  and  procedures  related  to  loan 
origination and securitization. In such cases, where contract claims 
are being pursued, the sponsor of the transaction is contractually 
obligated to repurchase, cure or substitute collateral for any loan 
that  breaches  the  representations  and  warranties.  However, 
generally the sponsors have not honored those obligations and have 
vigorously defended claims brought against them.

As  of  December 31,  2018,  we  have  estimated  RMBS  R&W 
subrogation  recoveries  of  $1,744.2  million  (net  of  reinsurance) 
included in our financial statements. These estimated recoveries 
are based on the contractual claims brought in the aforementioned 
litigations  and  represent  a  probability-weighted  estimate  of 
amounts we expect to recover under various possible scenarios.  
The estimated recoveries we have recorded do not represent the 
best or the worst possible outcomes with respect to any particular 
transaction or group of transactions. 

There can be no assurance that Ambac Assurance will be successful 
in prosecuting its claims in the RMBS litigations. The outcome of 
any  litigation,  including  the  RMBS  litigations,  is  inherently 
unpredictable,  including  because  of  risks  intrinsic  in  the 
adversarial nature of litigation. Motions made to the court, rulings 
and  appeals  could  delay  or  otherwise  impact  any  recovery  by 
Ambac Assurance.    Moreover,  rulings  that  may  be  adverse  to 
Ambac Assurance (in any of its RMBS litigations, as well as in 
other RMBS cases in which it is not a party) could affect Ambac 
Assurance’s  ability  to  pursue  its  claims  or  alter  settlement 
dynamics  with  RMBS  litigation  defendants.  For  example,  as 
described  in  Note  16.  Commitments  and  Contingencies  to  the 
Consolidated Financial Statements included in Part II, Item 8 in 
this Form 10-K, the defendants in Ambac Assurance’s case against 
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) are pursuing appeals of rulings issued in 
December 2018 on several pre-trial motions filed by defendants 
in August  2018  and  October  2018.  If  the  appeals  were  decided 

adversely to Ambac Assurance, in whole or in part, our ability to 
recover on our claims could be materially impaired. Furthermore, 
the timing of the decision on the appeals may significantly prolong 
the  timetable  of  any  recovery.  The  timing  of  decisions  by  trial 
courts and appellate courts is uncertain, and courts may take longer 
than expected to issue decisions.  A trial court may take longer than 
expected to schedule a trial in a case due to the schedule of the 
judge and the need or desire of the court to decide, or await the 
decision by an appellate court of, outstanding issues in the case.

Any litigation award or settlement may be for an amount less than 
the amount necessary to pay the Secured Notes or the Tier 2 Notes, 
which  could  have  a  material  adverse  effect  on  our  financial 
condition or results of operations and make it more difficult for 
Ambac Assurance to repay the Ambac Note (and therefore make 
it more difficult for the issuer of the Secured Notes to repay the 
Secured Notes) and/or the Tier 2 Notes and/or Ambac Assurance’s 
outstanding surplus notes, on a timely basis or at all. Additionally, 
while Ambac Assurance may pursue settlement negotiations, there 
can  be  no  assurance  that  any  settlement  negotiations  will 
materialize or that any settlement agreement can be reached on 
terms acceptable to Ambac Assurance, or at all. Depending on the 
length of time required to resolve these litigations, either through 
settlement  or  at  trial,  Ambac  Assurance  could  incur  greater 
litigation expenses than currently projected. If a case is brought to 
trial, Ambac Assurance’s ultimate recovery would be subject to the 
additional risks inherent in any trial, including adverse findings or 
determinations  by  the  trier  of  fact  or  the  court,  which  could 
adversely impact the value of our securities, including the Secured 
Notes and Tier 2 Notes.

Any litigation award is subject to risks of recovery, including that 
the sponsor is unable pay a judgment that Ambac Assurance may 
obtain in litigation. In some instances, Ambac Assurance also has 
claims against a parent or an acquirer of the counterparty. However, 
Ambac Assurance may not be successful in enforcing its claims 
against any successor entity.

The RMBS litigations could also be adversely affected if Ambac 
Assurance does not have sufficient resources to actively prosecute 
its  claims  or  becomes  subject  to  rehabilitation,  liquidation, 
conservation or dissolution, or otherwise impaired by actions of 
OCI.

Our  ability  to  realize  the  estimated  RMBS  R&W  subrogation 
recoveries included in our financial statements and the time of the 
recoveries, if any, is subject to significant uncertainty, including 
the  risks  described  above  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  all  such  amounts,  our  stockholders’  equity  as  of 
December 31,  2018  would  decrease  from  $1,633.1  million  to 
$(111.1) 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 Ambac Assurance  insures.  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 Ambac Assurance's interests, the performance of the 
collateral and assets backing the obligations that Ambac Assurance 
in 
the  performance  of  servicers 
insures,  and 

involved 

| Ambac Financial Group, Inc.   19   2018 FORM 10-K |

securitizations in which Ambac Assurance participates as insurer. 
Additionally,  our  ability  to  realize  recoveries  in  insured 
transactions  may  be  impaired  if  the  continuing  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, and may result in adverse consequences such 
as impairing the ability of Ambac Assurance to honor its financial 
obligations;  the  initiation  of  rehabilitation  proceedings  against 
Ambac  Assurance;  decreased  likelihood  of  Ambac  Assurance 
delivering value to Ambac, through dividends or otherwise; and a 
significant  drop  in  the  value  of  securities  issued  or  insured  by 
Ambac or Ambac Assurance, including the Secured Notes and Tier 
2 Notes.

Ambac’s  estimate  of  RMBS  litigation  recoveries  is  subject  to 
significant  uncertainty  and  changes  to  the  estimate  could 
adversely impact its liquidity, financial condition and results of 
operations.

For Ambac’s RMBS cases for which it records an RMBS R&W 
subrogation  recovery  in  its  financial  statements,  Ambac  has 
obtained  loan  files  from  the  relevant  original  pool  and  has 
conducted loan file reunderwriting to derive a breach rate that is 
extrapolated to estimate the damages Ambac expects to recover.  
Ambac does not estimate an RMBS R&W subrogation recovery 
for litigations where its sole claim is for fraudulent inducement. 

The  amount  estimated  for  purposes  of Ambac’s  RMBS  R&W 
subrogation  recovery  and  the  amount  Ambac  may  ultimately 
receive  is  subject  to  significant  uncertainty,  as  described  in  the 
immediately  preceding  risk  factor.    Ambac’s  findings  and 
assumptions  regarding  collateral  performance  and  Ambac’s 
expectations with respect to the outcome of the RMBS litigations 
have  a  significant  impact  on Ambac’s  estimated  RMBS  R&W 
subrogation recovery. If these findings, assumptions or estimates 
prove to be incorrect or otherwise do not support our claims, actual 
recoveries  could  differ  materially  from  those  estimated. Actual 
recoveries will ultimately depend on future events and there can 
be  no  assurance  that  our  view  of  collateral  performance  or  our 
estimated RMBS R&W subrogation recoveries will not differ from 
actual events. Although Ambac believes that its methodology for 
estimating  recoveries  is  appropriate,  the  methodologies Ambac 
uses to estimate expected collateral losses and specific transaction 
performance may not be similar to methodologies used by Ambac’s 
competitors,  counterparties  or  other  market  participants.  The 
determination of expected RMBS R&W subrogation recoveries is 
an inherently subjective and complex process involving numerous 
estimates and assumptions and judgments by management, using 
both  internal  and  external  data  sources  to  derive  a  specific 
transaction's  cash  flows. As  a  result, Ambac’s  current  estimates 
may  not  reflect  Ambac’s  ultimate  recovery,  and  management 
makes no representation that the actual amounts recovered, if any, 
will  not  differ  materially  from  those  estimated.  The  failure  of 
Ambac’s actual recoveries to meet or exceed its current estimates 
could  result  in  a  material  adverse  effect  on Ambac’s  financial 
condition, including its capital and liquidity. 

AMPS  that  were  not  exchanged  and  cancelled  in  the  AMPS 
Exchange may be acquired, redeemed or repaid on terms that 
may be viewed as more, or less, favorable than the terms of the 
applicable consideration offered in the AMPS Exchange.

Ambac or Ambac Assurance may acquire, redeem or repay AMPS 
that  were  not  exchanged  and  cancelled  in  the AMPS  Exchange 
through open market purchases, privately negotiated transactions, 
other tender or exchange offers, redemptions under the AMPS, or 
such other means as Ambac or Ambac Assurance (as the case may 
be) deems appropriate, subject to the restrictions in its governing 
documents,  the  restrictive  covenants  in  its  contracts  and  any 
applicable regulatory restrictions.  Any such transactions will occur 
upon the terms and at the prices as Ambac or Ambac Assurance 
(as the case may be) may determine in its sole discretion, which 
may  be  more  or  less  favorable  than  the  terms  of  the  AMPS 
Exchange, and in any case could be for cash or other consideration.  
Ambac or Ambac Assurance may choose to pursue any or none of 
these alternatives, or combinations thereof, in the future.

We may not be able to commute or reduce insured exposures.

In pursuing the objective of improving our financial position, we 
are seeking to commute or reduce insured exposures. De-risking 
transactions may not be feasible or economically viable.  We cannot 
provide  any  assurance  that  any  such  transaction  will  be 
consummated in the future, or if it is, as to the timing, terms or 
conditions of any such transaction.  Even if we consummate one 
or more of 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.

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  may  result  in  the  loss  of 
installment premium income from such insured transactions if the 
continuing  orders  of  the  Rehabilitation  Court  are  not  effective.  
Such reductions would result in lower revenues.

The  composition  of  the  securities  in  our  investment  portfolio 
exposes us to greater risk than before we invested in "alternative 
assets."

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 
Assurance  and/or  Ambac  UK  to  greater  earnings  volatility, 
increased  losses  and  decreased  liquidity  in  the  investment 
portfolio.

We may have future capital needs and may not be able to obtain 
third-party financing or raise additional third-party capital on 
acceptable terms, or at all.

An inability to obtain third-party debt financing or raise additional 
third-party  capital,  when  required  by  us  or  when  business 

| Ambac Financial Group, Inc.   20   2018 FORM 10-K |

conditions warrant, could have a material adverse effect on our 
business,  financial  condition  and  results  of  operations.    The 
economic conditions affecting our industry, as well as other factors, 
may constrain our financing abilities.  Our ability to secure third-
party  financing,  if  available,  and  to  satisfy  or  refinance  our 
financial obligations under indebtedness outstanding from time to 
time will depend upon regulatory conditions, our future operating 
performance,  the  availability  of  credit  generally,  economic 
conditions and financial, business and other factors, many of which 
are  beyond  our  control.    The  market  conditions  and  the 
macroeconomic conditions that affect our industry could have a 
material adverse effect on our ability to secure third-party financing 
on favorable terms, if at all.

If third-party financing is not available when needed, or is available 
on  unfavorable  terms,  we  may  be  unable  to  take  advantage  of 
business  opportunities,  respond  to  competitive  pressures  or 
refinance our outstanding indebtedness, any of which could have 
a material adverse effect on our business, financial condition and 
results of operations.

Ambac  Assurance  may  in  the  future  report  a  policyholders’ 
deficit or become insolvent.

While the Rehabilitation Exit Transactions and related transactions 
were designed to improve our financial condition, we will continue 
to be subject to risks and uncertainties that could materially affect 
our financial position.  Therefore, even following consummation 
of the Rehabilitation Exit Transactions, circumstances may occur 
that  would  cause  Ambac  Assurance  to  report  a  policyholders’ 
deficit  or  not  comply  in  the  future  with  the  statutory  minimum 
policyholders’  surplus  or  undergo  rehabilitation.    In  addition, 
Ambac Assurance may become insolvent in the future.  OCI has 
prescribed or permitted additional accounting practices for Ambac 
Assurance and Everspan 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.  If Ambac Assurance 
and  Everspan  are  unable  to  utilize  the  permitted  or  prescribed 
practices,  we  may  not  comply  with  the  statutory  minimum 
policyholders’ surplus.

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 financial models and tools to 
project impairments with respect to RMBS held in our investment 
portfolio, 
including  Ambac  Assurance  guaranteed  RMBS. 
Differences in the models and tools we employ and/or flaws in 
these models and tools and/or faulty assumptions inherent in these 
models and tools 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.

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  debt  obligations,  to  meet  collateral  posting 
requirements or to meet other liquidity needs, 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  
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.  In addition, the Company from time 
to  time  receives  various  regulatory  inquiries  and  requests  for 
information. Please see Note 16. 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 
against  Ambac,  Ambac  Assurance  or  one  or  more  other 
subsidiaries 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, Stipulation and Order and Indenture 
for the Tier 2 Notes contain restrictive covenants that may impair 
our ability to pursue our business strategies.

Pursuant to the terms of the Settlement Agreement, Stipulation and 
Order and indenture for the Tier 2 Notes, Ambac Assurance must 
seek  prior  approval  by  OCI  of  certain  corporate  actions.  The 
Settlement Agreement, Stipulation and Order and indenture for the 
Tier 2 Notes also include covenants which restrict the operations 
of  Ambac  Assurance  which,  (i)  in  the  case  of  the  Settlement 
Agreement, remain in force until the surplus notes that were issued 
pursuant  to  the  Settlement  Agreement  have  been  redeemed, 
repurchased or repaid in full, (ii) in the case of the Stipulation and 
Order,  remain  in  place  until  the  OCI  decides  to  relax  such 
restrictions,  and  (iii)  in  the  case  of  the  indenture  for  the Tier  2 
Notes, remain in force until the Tier 2 Notes have been redeemed, 
repurchased or repaid in full. Certain of these restrictions may be 
waived  with  the  approval  of  holders  of  the  applicable  debt 
securities  and/or  OCI.  If  we  are  unable  to  obtain  the  required 
consents  under  the  Settlement Agreement,  the  Stipulation  and 
Order and/or the indenture for the Tier 2 Notes, we may not be able 
to execute our planned business strategies.

OCI has certain enforcement rights with respect to the Settlement 
Agreement and Stipulation and Order. 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. Any  such 
dispute  could  have  material  adverse  effects  on  the  Company, 
whether 
proceedings, 
supervisory  orders,  failure  to  execute  transactions  sought  by 
management, interference with corporate strategies, objectives or 
prerogatives,  inefficient  decision-making  or  execution,  forced 
realignment  of  resources, 
to 
management, strained working relationships or otherwise. Such 

increased  costs,  distractions

litigation, 

through 

effects would also increase the risk that OCI would seek to initiate 
rehabilitation proceedings against Ambac Assurance.

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,  cause  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 
activities 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 depends 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,  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

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.

The  Government  of  the  United  Kingdom  (“UK”)  continues  to 
contend  with  inconclusively  finding  resolution  in  the  UK 
Parliament and with the European Union (“EU”) for the terms of 
the  UK’s  departure  from  the  EU  (“Brexit”).      Current  Brexit 
discussions  do  not  include  details  of  future  post-Brexit  trade 
relations. Current negotiations are designed to reach agreement on 
transitional  arrangements  covering  the  UK’s  exit  from  the  EU, 
lasting only for a relatively brief period, currently mooted to endure 
from March 29, 2019, the anticipated date of formal UK departure 
from the EU, and end on December 31, 2020.  Assuming a transition 
agreement  is  reached,  a  further,  separate,  negotiation  on  a 
future post-transition  trade  framework  must  then  begin.    It  is 
envisaged that negotiation on the future trade framework would 
be  concluded  during  the  transitional  phase,  and  would  be 
influenced by the nature of the transitional arrangements agreed 
between the parties.  

However  there  is  a  material  risk  that  transitional  Brexit 
negotiations are inconclusive so that on March 29, 2019 the UK 
automatically exits the EU without any transitional arrangement 
(a “no deal Brexit”), and also with no certain path to negotiating 
a future trade relationship with the EU.

Absent action by the EU or member states, in the event of a no 
deal Brexit the activities in the European Economic Area (“EEA”) 
of UK passporting insurers, including Ambac UK, will become 
unlawful  on  March  29,  2019.  They  will  lose  their  legal 
authorization to serve clients who benefit from policies issued by 
UK incorporated insurers under freedom of services passporting 

rights (and thereby may be unable to legally collect premiums or 
pay claims). 

At December 31, 2018, Ambac UK’s insured portfolio included 
six policies in the EU written under current passporting rights, with 
an  aggregate  par  value  of  $2.4  billion.    In  respect  of  these  six 
policies, there is premium receivable of $61 million and loss and 
loss  expense  reserves  (net  of  subrogation  recoverable)  of  $271 
million.  Absent legally binding transitional arrangements Ambac 
UK may be unable to collect these premiums or pay the claims to 
which  these  premiums  receivable  and  loss  and  loss  expense 
reserves  relate  after  March  29,  2019.   Ambac  UK’s  ability  to 
restructure  these  policies  to  mitigate  this  risk  is  limited. 
Nonpayment of claims under any of the affected policies could 
lead to the loss of control rights in the related transaction(s), which 
would expose Ambac UK to greater risk of loss.  In addition, under 
applicable English law, a court may hold that Ambac UK has an 
enforceable  obligation  to  pay  claims  irrespective  of  the  EU 
regulatory position in law.  Consequently Ambac UK could find 
itself in a position where it was not in receipt of premium on a 
relevant deal but chose to pay claims to avoid loss of control rights 
and/or other consequences of non-payment, notwithstanding the 
EU regulatory characterization in law.

Additionally, if UK insurers have branches in EEA Member States 
they may be legally obliged to either capitalize them, as a so-called 
third  country  branch  from  an  institution  whose  home  state  is 
outside  the  EEA,  or  close  them  down  and  no  longer  be  legally 
represented in those EU jurisdictions. Ambac UK has a branch in 
Italy, with one remaining policy issued from the branch. The branch 
is not capitalized separately from Ambac UK.  In the event of a 
no-deal Brexit, the future nature and status of the branch is unclear, 
particularly with respect to the need for capitalization to support 
the one remaining branch policy.  Given that Ambac UK is under 
capitalized in terms of applicable regulatory capital rules it will be 
difficult for the UK regulator to agree to assets leaving the company 
for this purpose. 

then  be 

There  is  a  risk  that  absent  agreement  with  the  Italian  regulator 
regarding the future of the branch, under law the Italian regulator 
could institute insolvent winding up proceedings against the branch 
as an unlicensed insurance business. In this scenario the one branch 
policy  would

notwithstanding the prejudicial outcome to policy holders.    This 
chain  of  events  could  in  turn  trigger  cross  defaults  with  a 
consequential loss by Ambac UK of its controlling creditor rights 
in many or all transactions.  This would greatly inhibit Ambac UK’s 
ability  to  exercise  its  rights  in  transactions  generally,  and  in 
particular with respect to mitigating potential or actual loss in those 
transactions.

terminated  by  operation  of 

In light of no deal Brexit risk, the UK financial regulatory authority 
has been actively encouraging regulated firms to put into place 
contingency  plans,  as  have  been  EU  and  EU  member  states’ 
financial regulatory bodies.  

However  on  February  19,  2019,  the  European  Insurance  and 
Occupational  Pensions  Authority  (“EIOPA”)  made  a  series  of 
recommendations to EU insurance regulators in light of Brexit.

orderly  run  off  (without  time  limit)  branch  operations  and  of

prior  to  March  30,  2019  that  terminate  after  this  date.    The 
recommendations will require to be incorporated into EEA member 
states legal and regulatory frameworks in an appropriate manner 
to bring them into effect.  We can provide no assurance as to the 
manner or timing of such regulatory changes.

The Company is in discussion with the PRA and other relevant 
regulatory authorities to enable the continued orderly run off of 
its policies issued in the EEA under passporting rights as well as 
the Italian branch operation in line with this recommendation.

In addition to the direct impact on insurers cited above, general 
uncertainty and the perceptions as to the ultimate impact of Brexit 
may adversely affect business activity, political stability, foreign 
exchange rates and economic conditions in the UK, the Eurozone, 
and the EU.

Actions of the PRA and FCA could reduce the value of Ambac 
UK  realizable  by  Ambac,  which  would  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 
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 
whether 
  Accordingly, 
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 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”.  

Ambac UK clearly falls into this category and therefore Ambac 
UK’s current run off approach remains at all times subject to the 
PRA continuing to take no action 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.

Risks Related to Taxation

Surplus notes received in the AMPS Exchange and by holders 
of Deferred Amounts pursuant to the Second Amended Plan of 
Rehabilitation along with other debt reissued  by Ambac may not 
be  fungible  for  U.S.  federal  income  tax  purposes  with  other 
surplus notes and debt currently outstanding. 

Surplus notes received in the AMPS Exchange and by holders of 
Deferred  Amounts  pursuant  to  the  Second  Amended  Plan  of 
Rehabilitation along with other debt reissued by Ambac  (together 
"Reissued  Debt")  have  different  issue  prices  for  U.S.  federal 
income tax purposes than the originally issued outstanding surplus 
notes and other debt and, therefore, are expected to accrue original 
issue discount (“OID”) in an amount that differs from the amounts 
of OID accruing on the originally issued surplus notes and other 
debt currently outstanding, as the case may be.  Therefore, Reissued 
Debt may not be fungible with the other outstanding surplus notes 
and  debt,  as  applicable,  for  U.S.  federal  income  tax  purposes. 
Because  Reissued  Debt  has  the  same  CUSIP  numbers  as  other 
related  surplus notes and debt currently outstanding, the Reissued 
Debt will not be readily distinguishable from the other outstanding 
surplus notes and debt, as applicable.  This could create uncertainty 
in the market and could adversely affect the liquidity and/or trading 
values of surplus notes and other debt.

Certain surplus notes or other obligations of Ambac Assurance 
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  of 
Ambac  Assurance  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  net  operating 
loss  carry-forwards  ("NOLs")  (and  certain  other  available  tax 
attributes  of  Ambac  Assurance  and  the  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 

| Ambac Financial Group, Inc.   24   2018 FORM 10-K |

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.

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, 
amongst other things, 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 into new businesses, including 
new businesses apart from Ambac Assurance, is also subject to 
significant  doubt,  given  the  financial  condition  of  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 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

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, 2018, with the Russell 2000 Index and S&P Completion Index. 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 
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.

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 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.

COMPANY OVERVIEW

See Note 1. Background and Business Description for a description 
of the Company and our key strategies to achieve our primary goal 
to maximize shareholder value.

EXECUTIVE SUMMARY

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 
with Ambac's liability management and loss mitigation programs.  

Asset Management:

Investment portfolios are subject to internal investment guidelines, 
as well as 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 
relative risk/reward characteristics.  The investment portfolios of 
Ambac  Assurance  and  Ambac  UK  also  hold  fixed  income 
securities and pooled funds that include a variety of other assets 
including, but not limited to, corporate bonds, asset backed and 

| Ambac Financial Group, Inc.   29   2018 FORM 10-K |

mortgage backed securities, municipal bonds, high yield bonds, 
leveraged loans, equities, real estate, insurance-linked securities 
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 fixed income investments by asset class.

During the year ended December 31, 2018, Ambac (inclusive of 
its subsidiaries) did not acquire a significant amount of distressed 
Ambac-insured securities.  As a result of the Rehabilitation Exit 
Transactions  (as  defined  in  Note  1.  Background  and  Business 
Description), Ambac discharged all Deferred Amount (as defined 
in Note 1. Background and Business Description) obligations for 
an effective consideration package comprised of cash, new Secured 
Notes (as defined in Note 1. Background and Business Description) 
and certain existing surplus notes, including those held by Ambac, 
and  accordingly Ambac's  ownership  of Ambac-insured  RMBS 
declined significantly.  Furthermore, Ambac sold certain Ambac-
insured  RMBS  securities  during  2018  in  connection  with  re-
balancing  the  investment  portfolio  and  certain  Ambac-insured 
student  loan  securities  in  connection  with  a  commutation 
transaction.  At December 31, 2018, Ambac owned $254 million 
of Ambac-insured RMBS and approximately 37% of outstanding 
Puerto  Rico  Infrastructure  Financing Authority  ("PRIFA")  and 
58%  of  outstanding Ambac-insured  bonds  issued  by  the Puerto 
Rico  Sales Tax  Financing  Corporation  ("COFINA").  Subject  to 
applicable internal and regulatory guidelines and other constraints, 
Ambac will continue to opportunistically purchase Ambac-insured 
securities. 

Liability and Insured Exposure Management:

Ambac Assurance's Risk Management Group ("RMG") focuses 
on the analysis, implementation and execution of risk reduction, 
remediation and loss recovery strategies for the insured portfolio. 
Analysts evaluate the estimated timing and severity of projected 
policy claims as well as the potential impact of loss mitigation or 
remediation measures in order to target and prioritize policies, or 
portions  thereof,  for  commutation,  reinsurance,  refinancing, 
restructuring or other risk 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 2018, Ambac's successes included:

•  Working  closely  with  servicers  and  owners  of  Master 
Servicing  Rights  to  exercise  clean-up  calls  on  11  RMBS 
transactions, reducing adversely classified net par exposure 
by $284 million;

•  Proactively working with issuers to expedite refundings or 
restructurings of Ambac-insured international bonds.  During 
2018, Ambac negotiated with counterparties that resulted in 
the  termination  of  several  international  RMBS  and  asset-
backed policies on £182 million and £548 million of net par 
exposure, respectively;

•  Working with issuers and other transaction counterparties to 
expedite  refundings  or  calls  across  a  number  of  Ambac 
domestic  public  finance  bonds,  resulting  in  a  reduction  of 
watch list and adversely classified net par of approximately 
$1.0 billion; 

•  Working with issuers and investors of Ambac-insured debt to 
commute $484 million of net par exposure, including $127 
million of adversely classified student loan exposures; and

•  Facilitating the refinancing of a defaulted Ambac UK insured 
debt, reducing adversely classified net par exposure by $36 
million;

•  Sculpting  the  risk  profile  of  the  insured  portfolio  through 
quota share reinsurance.  This included ceding approximately 
$138  million  of  structured  finance  exposure  and  the  full 
amount  of  certain  public  finance  exposures  totaling  $1.5 
billion of performing par exposure (principal and interest of 
$3.4 billion), which was mostly comprised of policies on non-
callable capital appreciation bonds and included $232 million 
par of watch list and adversely classified credits.

The  following  table  provides  a  comparison  of  total,  adversely 
classified credits ("ACC") and watch list net par outstanding in the 
insured  portfolio  at  December  31,  2018  and  2017.    Net  par 
exposures within the U.S. public finance market includes capital 
appreciation bonds which are reported at the par amount at the time 
of  issuance  of  the  insurance  policy  as  opposed  to  the  current 
accreted value of the bonds.

The overall reduction in total net par outstanding resulted from 
scheduled maturities, amortizations, commutations, reinsurance, 
refundings, refinancings and calls, including reductions as a result 
of the activities of Ambac and its subsidiaries as noted above.

The decreases in adversely classified credit exposures and watch 
list credit exposures are primarily due to (i) results of active risk 
reductions; (ii) paydowns or calls by issuers; and (iii) for adversely 
classified credits, the improved credit profile of certain residential 
mortgage-backed securities and their upgrade from the adversely 
classified credit listing. 

Although our insured portfolio generally performed satisfactorily 
in  2018,  we  continue  to  experience  stress  in  certain  insured 
exposures, particularly within our approximately $1.9 billion of 
exposure  to  Puerto  Rico,  consisting  of  several  different  issuing 
entities (all below investment grade). Each issuing entity has its 
own  credit  risk  profile  attributable  to.  as  applicable,  discrete 
revenue sources, direct general obligation pledges and/or general 
obligation guarantees.  On February 4, 2019, the COFINA Plan of 
Adjustment ("POA") was confirmed by the United States District 
Court  for  the  District  of  Puerto  Rico  and  became  effective  on 
February  12,  2019.  Several  parties  are  presently  appealing  the 
confirmation of the POA and no assurances can be given regarding 
the  results  of  such  appeals.  The  POA  and  certain  related 
commutation  transactions  resulted  in  a  reduction  of  Ambac 
Assurance's insured exposure to COFINA by approximately 75% 
or $603 million to $202 million and a reduction in overall Puerto 
Rico exposure to $1.3 billion from $1.9 billion at December 31, 
2018. Refer to Part II, Item 7. Financial Guarantees in Force in 
this  Annual  Report  on  Form  10-K  for  additional  information 
regarding  the  different  issuing  entities  that  encompass Ambac's 
exposures to Puerto Rico as well as the COFINA POA.

•  Additional clean-up calls on two RMBS transactions on the

•  Worked  with  the  issuer  of  two  watch  list  asset  backed 
securitizations to expedite the refunding of the bonds with  
net par outstanding of $95 million at December 31, 2018; and

•  Worked with an issuer to commute, via a first quarter 2019 
refunding, an adversely classified public finance transaction 
with  net  par  outstanding  of  $350  million  at  December  31, 
2018.

During  2018, Ambac  repaid  the  remaining  December  31,  2017 
balance of the Secured Borrowing (as defined and described in 
Note 3. Variable Interest Entities) of $74 million and made partial 
paydowns of the Ambac Note (as defined in Note 1. Background

Tolling  payments  are  subject  to  review  and  approval  by  OCI  as

As a result of positive taxable income at Ambac Assurance in 2017, 
Ambac  accrued approximately $30 million in tax tolling payments.  
In May 2018, Ambac executed a waiver under the intercompany 
Tax Sharing Agreement pursuant to which Ambac Assurance was 
relieved of the requirement to make this payment  by June 1, 2018.  
Ambac also agreed to continue to defer the tolling payment for the 
use of net operating losses in 2017 by Ambac Assurance until such 
time  as  OCI  (as  defined  in  Note  1.  Background  and  Business 
Description) consents to the payment.

For  the  year  ended  December  31,  2018,  Ambac  Assurance 
recognized taxable income and accordingly Ambac has accrued 
$14 million of tolling payments. Pursuant to the Stipulation and 
Order, Ambac's  tax positions  are subject  to review by the  OCI, 
which may lead to the adoption of positions that reduce the amount 
of tolling payments otherwise available to Ambac.

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  are  most 
important to the portrayal of the Company's financial condition; 
and  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  certain  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 (including 
Subrogation Recoverables):

The  loss  and  loss  expense  reserves,  including  subrogation 
recoverables ("loss reserves"), discussed in this section relate only 
to 
to  Ambac’s  non-derivative 
beneficiaries,  including  unconsolidated  VIEs.  Ambac's  loss 
reserves include loss reserve components of an insurance policy, 
consisting of the present value ("PV") of expected net cash flows 
to be paid (or received) under an insurance contract and unpaid 

insurance  policies 

issued

claims.  The PV of expected net cash flows represents the PV of 
expected cash outflows (future losses) less the PV of expected cash 
inflows (future recoveries) discounted at a risk-free discount rate. 
Unpaid claims represents claims that were not paid for policies 
allocated  to  the  Segregated  Account  (as  defined  in  Note  1. 
Background and Business Description in the Notes to Consolidated 
Financial  Statements  included  in  this    Report  on  Form  10-K), 
including Deferred Amounts (as defined in Note 1. Background 
and Business Description in the Notes to Consolidated Financial 
Statements included in this  Report on Form 10-K) and accrued 
interest.  In  2018,  all  Deferred  Amounts  were  settled  via  the 
  (as  defined  in  Note  1. 
Rehabilitation  Exit  Transactions 
Background and Business Description in the Notes to Consolidated 
Financial  Statements  included  in  this    Report  on  Form  10-K); 
therefore, unpaid claims are no longer included as a component of 
loss  reserves.    Refer  to  Note  1.  Background  and  Business 
Description  in  the  Notes  to  Consolidated  Financial  Statements 
included  in  this  Form  10-K  for  further  information  on  the 
Rehabilitation  Exit  Transactions.    While  unpaid  claims  were 
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 
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 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 but since Ambac 
currently has minimal exposure ceded to reinsurers on credits with 
loss reserves, the existing reinsurance contracts are unlikely to have 
a significant effect on loss reserve volatility. Loss reserve volatility 
will also be materially impacted by changes in interest rates from 
period to period.

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 of each 
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 related probabilities, 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  existing  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  the  potential  outcome  of  remediation  strategies. 
Remediation scenarios may include; (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  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  expectation  to  commute  additional  exposure  with  other 
counterparties. 

RMBS Expected Loss Estimate

insured  RMBS 

Ambac  insures  RMBS  transactions  collateralized  by  first-lien 
transactions 
mortgages.  Ambac  has  also 
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 may 

carry  a  significantly  higher  severity  in  the  event  of  a  loss, 
approaching or exceeding 100%. 

Ambac primarily utilizes a cash flow model (“RMBS cash flow 
model”) to develop estimates of projected losses for both our first 
and second lien transactions. First, the RMBS cash flow model 
projects  collateral  performance  utilizing:  (i) the  transaction’s 
underlying  loans'  characteristics  and  status,  (ii) projected  home 
price  appreciation  (“HPA”)  and (iii) projected  interest  rates. 
Depending in the amount of collateral information available for 
each transaction, we project such performance either at the  loan-
level  or  the  deal-level.    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. 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.  Projected servicer-level behavior may also have 
an impact on transaction performance. 

We source HPA projections from a market accepted vendor and 
interest rate projections are developed from market sources. 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.  

For the liabilities of the transaction which we insure, we generally 
utilize waterfall projections generated from a tool provided by a 
market  accepted  vendor. 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  projections  and  our 
understanding of the transactions’ structures to identify and resolve 
discrepancies.  We  also  systematically  review  the  vendor’s 
identify  material 
published  waterfall  revisions 
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 therefore need to be updated and reflected in our models 
through  time. As  such,  we  conduct  regular  reviews  of  current 
models,  alternative  models  and  the  overall  approach  to  loss 
estimation.

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 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 

| Ambac Financial Group, Inc.   33   2018 FORM 10-K |

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.  Ambac does not estimate an RMBS R&W subrogation 
recovery  for  litigations  where  its  sole  claim  is  for  fraudulent 
inducement, since any remedies under such claims would be non-
contractual.

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.  
Failure  to  realize  RMBS  R&W  subrogation  recoveries  for  any 
reason or the realization of  RMBS R&W subrogation recoveries 
materially below the amount recorded on Ambac's consolidated 
balance sheet would have a material adverse effect on our results 
of operations and financial condition and may result in adverse 
consequences such as impairing the ability of Ambac Assurance 
to honor its financial obligations; the initiation of rehabilitation 
proceedings  against Ambac Assurance;  decreased  likelihood  of 
Ambac Assurance delivering value to Ambac, through dividends 
or otherwise; and a significant drop in the value of securities issued 
or insured by Ambac or Ambac Assurance.  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 RMBS 
R&W subrogation recoveries, and to Part I, Item 1A. Risk Factors

subrogation recoveries. 

Student Loan Expected Loss Estimate

The  student  loan  portfolio  consists  of  credits  collateralized 
by private student loans.  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  the 
issuer,  servicers,  special  servicers,  and  administrators,  investor 
appetite for tendering or commuting insured obligations and, as 
applicable, Ambac’s ability and willingness to commute policies. 
In addition, we consider in our student loan loss projections the 
potential impact, if any, of proposed or final regulatory actions or 
orders, including by the Consumer Financial Protection Bureau 
("CFPB"), affecting our insured transactions.

In evaluating our student loan portfolio, our losses are projected 
using a cash flow modeling approach. In order to project collateral 
performance  under  the  cash  flow  approach,  we  use  a  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.  The 
then 
incorporated into a waterfall tool to develop loss estimates for our 
exposures. This waterfall tool 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. 

losses  are 

transaction 

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 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 losses for insurance policies 
discussed above could be understated, or that our estimated future 
recoveries  could  be  overstated.  We  have  attempted  to  identify 
possible cash flows related to losses and recoveries using more 
stressful  assumptions  than  the  probability-weighted  outcome 
recorded. The possible net cash flows consider the highest stress 
scenario that was utilized in the development of our probability-
weighted  expected  loss  at  December 31,  2018  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 relating to losses 
and  recoveries.    In  arriving  at  such  view,  management  makes 
considerable  judgments  about  the  possibility  of  various  future 
events.  Although we do not believe it is possible to have worst 
case outcomes in all cases, it is possible we could have worst case 
outcomes in some or even many cases.  See “Risk Factors” in Part 
I, Item 1A of this Form 10-K for further discussion of the risks 
relating to future losses and recoveries that could result in more 
highly  stressed  outcomes.  The  occurrence  of  these  stressed 
outcomes  individually  or  collectively  would  have  a  material 
adverse effect on our results of operations and financial condition 
and may result in materially adverse consequence for the Company, 
including  (without  limitation)  impairing  the  ability  of  Ambac 
Assurance  to  honor  its  financial  obligations;  the  initiation  of 
rehabilitation  proceedings  against Ambac Assurance;  decreased 
likelihood  of  Ambac  Assurance  delivering  value  to  Ambac, 
through dividends or otherwise; and a significant drop in the value 
of securities issued or insured by Ambac or Ambac Assurance.  

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 

| Ambac Financial Group, Inc.   34   2018 FORM 10-K |

characterized by growing unemployment and wage pressures, and/
or illiquidity of the mortgage market. We utilize a model to project 
losses  in  our  RMBS  exposures  and  changes  to  reserves,  either 
upward or downward, are not unlikely if we were to use a different 
model  or  methodology  to  project  losses.  We  regularly  assess 
models and methodologies and may change our approach and/or 
model  at  any  time.    Additionally,  our  RMBS  R&W  actual 
subrogation  recoveries  could  be  significantly  lower  than  our 
estimate  of  $1,744.2  million  as  of  December 31,  2018  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 possible 
stress case assumes a lower housing price appreciation projection, 
which  in  turn  drives  higher  defaults  and  severities.  Using  this 
approach, the possible increase in loss reserves for RMBS credits 
for which we have an estimate of expected loss at  December 31, 
2018  could  be  approximately  $30  million.    Combined  with  the 
absence of any RMBS R&W subrogation recoveries, a possible 
increase in loss reserves for RMBS could be approximately $1.8 
billion.   Additionally, loss payments are sensitive to changes in 
interest  rates,  increasing  as  interest  rates  rise.    For  example  an 
increase in interest rates of 0.50% could increase our estimate of 
expected losses by approximately $30 million.  There can be no 
assurance that losses may not exceed such amounts.

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 unfavorable 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 of adjustment, 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 expect municipal bankruptcies and defaults to continue to be 
challenging to project given the unique political, economic, fiscal, 
governance and public 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, resulting from reduced 
or no access to alternative forms of credit (such as bank loans) or 
other exogenous factors, such as the Tax Cuts and Jobs Act that 
was signed into law on December 22, 2017, which  contributed in 
part to the overall 21.6% decline in municipal issuance volume   in 
2018.  The primary contributor of the Tax Cuts and Jobs Act to 
lower  municipal  volumes  in  2018  was  the  elimination  of  tax-
exempt advance refundings.  In addition, the Tax Cuts and Jobs 
Act could potentially reduce municipal investor appetite for tax-
exempt municipal bonds by corporate investors and over the longer 
term could potentially put additional pressure on issuers in states 
with high state and local taxes. These factors could deprive issuers 
access to funding at a level 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 
uncertainty 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, limited capital markets access, political risk and 
aftereffects of the damage caused by hurricanes Irma and Maria.  
These  factors,  taken  together  with  the  payment  moratorium  on 
its 
certain  debt  payments  of 
instrumentalities,  ongoing Puerto Rico Oversight, Management, 
and Economic Stability Act ("PROMESA") Title III proceedings, 
and certain other provisions under PROMESA, the potential for a 
restructuring of debt insured by Ambac Assurance, either with or 
without its consent, and the possibility of protracted litigation as 
a result of which its rights may be materially impaired, may cause 
losses to exceed current reserves in a material manner. 

the  Commonwealth  and 

On February 4, 2019, the COFINA Plan of Adjustment ("POA") 
under Title III was confirmed by the United States District Court 
for the District of Puerto Rico and became effective on February 
12, 2019. Several parties are presently appealing the confirmation 
of the POA and no assurances can be given regarding the outcome 
of such appeals. The POA, which emerged from a consensually 
negotiated  Plan  Support  Agreement  executed  in  August  2018, 
resolved the COFINA Title III case and restructuring.  Among other 
things,  the  POA  and  certain  related  commutation  transactions 
resulted in a reduction of Ambac Assurance's insured exposure to 
COFINA by approximately 75% and provided for a nominal initial 
recovery amount in new COFINA bonds and cash equivalent to 
approximately  93%  of  the  Petition  Date  (May  5,  2017)  claim 
amount  on  the  remaining  approximately  25%  non-commuted 
policy  portion  of  Ambac  Assurance's  insured  exposure  to 
COFINA.  The  Ambac  Assurance-insured  COFINA  bonds  that 
comprise  such  non-commuted  exposure,  together  with  such 
remaining  policy  portion  of  Ambac  Assurance's  COFINA 
exposure,  have  been  deposited  into  a  trust,  as  have  the  non-
commuted  bondholders'  portion  of  the  new  bonds  issued  by 
COFINA and cash paid by COFINA under the POA, in exchange 
for  which 
the  non-commuted  Ambac-insured  bondholders 
received  units  of  the  trust  in  return  representing  undivided 
fractional interests in the trust property.  Cash flows from the new 
COFINA bonds and cash will be passed through to unit-holders 
over  time  and  will  reduce  amounts  owed  under  the  Ambac 
Assurance  policy  with  respect  to  the Ambac Assurance-insured 
COFINA  bonds.  There  are  no  assurances  that  future  debt

restructurings  for  other Ambac Assurance-insured  Puerto  Rico 
instrumentalities subject to Title III proceedings or otherwise will 
reach  a  similar  negotiated  structure  and  outcome;  any  such 
restructurings  could  therefore  cause  losses  to  exceed    current 
reserves in a material manner.      

See "Financial Guarantees in Force" below for further details on 
the legal, economic, fiscal, and  political developments that have 
impacted or may impact Ambac Assurance’s insured Puerto Rico 
bonds. 

Material additional losses caused by the above-described factors 
would have a material adverse effect on our results of operations 
and  financial  condition.  For  public  finance  credits,  including 
Puerto Rico as well as other issuers, for which we have an estimate 
of expected loss at December 31, 2018, the possible increase in 
loss reserves could be approximately $1.0 billion.  However, there 
can be no assurance that losses may not exceed such amount.   

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. Such  factors  may  include  lower  recoveries  on 
defaulted loans or additional losses on collateral or trust assets, 
including as a result of any enforcement actions of the Consumer 
Finance Protection Bureau. For student loan credits for which we 
have  an  estimate  of  expected  loss  at  December 31,  2018,  the 
possible  increase  in  loss  reserves  could  be  approximately  $25 
million. Additionally, an increase in interest rates of 0.50% could 
increase  our  estimate  of  expected  losses  by  approximately  $25 
million.  There can be no assurance that losses may not exceed 
such amount.

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. For all other credits, including Ambac UK, for which 
we have an estimate of expected loss, the sum of all the highest 
stress case loss scenarios is approximately $170 million greater 
than the loss reserves at December 31, 2018. However, there can 
be no assurance that losses may not exceed such amount.  

Valuation of Certain Financial Instruments:

The Fair Value Measurement Topic of the ASC requires financial 
instruments  to  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 to the Consolidated Financial 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.  
Level  3  instruments  are  valued  using  models  which  use  one  or 
more significant inputs or value drivers that are unobservable and 
judgment.  Level  3  financial 
therefore  require  significant 

instruments  which  are  material  include  uncollateralized  interest 
rate swaps, investments and loan receivables of consolidated VIEs 
and  certain  VIE  debt  obligations.  Model-derived  valuations  of 
Level 3 financial instruments incorporate estimates of the effects 
of Ambac's own credit risk and/or counterparty credit risk, which  
can  be  complex  and  judgmental.    Furthermore,  Level  3  loan 
receivables of consolidated VIEs incorporate estimates of  Ambac's 
financial  guarantee  cash  flows,  including  future  premiums  and 
losses.  Such  cash  flow  estimates  require  judgments  regarding 
prepayments of VIE debt, loss probabilities and  loss severities, all 
of which are inherently uncertain.

All models and related assumptions are continuously re-evaluated 
by  management  and  enhanced,  as  appropriate,  based  on 
improvements in information and modeling techniques. The re-
evaluation process includes a quarterly meeting of senior Finance 
personnel  to  review  and  approve  changes  to  models  and  key 
assumptions. 

As  a  result  of  the  significant  judgment  for  the  above-described  
instruments, the actual trade value of the financial instrument in 
the  market,  or  exit  value  of  the  financial  instrument  owned  by 
Ambac, may be significantly different from its recorded fair value. 

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 Tax  Cut  and  Jobs Act  ("TCJA")  was  enacted  in  December 
2018  and  introduced  significant  changes  to  the  U.S.  tax  code 
effective  January  1,  2018.  The  U.S.  NOL  component  of  the 
deferred tax asset expires if not utilized 20 years from when the 
NOL  was  generated.  However,  NOLs  generated  from  non-
insurance activity after the effective date of the TCJA are carried 
forward  indefinitely.  Valuation  allowances  are  established  to 
reduce deferred tax assets  to an amount that “more likely than not” 
will be realized. On a quarterly basis, management identifies and 
considers  all  available  evidence,  both  positive  and  negative,  in 
making  the  determination  with  significant  weight  given  to 
evidence  that  can  be  objectively  verified.  Negative  evidence 
includes  the  potential  for  unrecognized  future  insurance  losses; 
uncertainty  regarding  timing  and  magnitude  of  RMBS  R&W 
litigation  recoveries;  no  new  financial  guarantee  business  and 
execution risk of any new business venture.   Positive evidence 
includes the Segregated Account's exit from rehabilitation further 
described in Note 1. Background and Business Description in the 
Notes  to  Consolidated  Financial  Statements  included  in  this  
Report on Form 10-K. 

| Ambac Financial Group, Inc.   36   2018 FORM 10-K |

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 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  U.S.  deferred  tax  asset  and  therefore  has  a  full  valuation 
allowance. To the extent significant uncertainties such as Puerto 
Rico losses, RMBS R&W litigation and new business ventures are 
resolved, Ambac  may  have  the  ability  to  establish  a  history  of 
making reliable estimates of future income which could ultimately 
result in a reduction to the deferred tax asset valuation allowance.  
See  Note  14.  Income  Taxes  for  additional  information  on  the 
Company's  deferred  income  taxes,  including  the  effects  of  the 
TCJA.

FINANCIAL GUARANTEES IN FORCE

The following table provides a breakdown of guaranteed net par 
outstanding by market sector at December 31, 2018 and 2017.  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    as  opposed  to  the  current 
accreted  value  of  the  bonds.    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:

are reported at the par amount at the time of issuance of the related 
insurance policy as opposed to the current accreted value of the bonds. 
As  discussed  below  under  Puerto  Rico,  the  COFINA  POA  was 
confirmed by the United States District Court for the District of Puerto 
Rico on February 4, 2019 and became effective on February 12, 2019. 
The POA and certain related commutation transactions resulted in a 
reduction  of Ambac Assurance's  insured  exposure  to  COFINA  by 
approximately 75% or $603 to $202.

U.S. Public Finance Insured Portfolio 

Ambac’s  portfolio  of  U.S.  public  finance  exposures  is  $23,442 
million, representing 50% of Ambac’s net par outstanding as of 
December 31,  2018  and  a  27%  reduction  from  the  amount 
outstanding at December 31, 2017. This reduction in exposure was 
due to additional reinsurance acquired, exposure runoff, and early 
terminations  (calls,  refundings  and  pre-refundings).  While 
Ambac’s U.S. public finance portfolio consists predominantly of 
municipal bonds such as general obligation, revenue, 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  and  similar  proceedings,  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, 
trends, 
competitive  position, 
government programs and other factors. 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, privatized military housing 
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 $6 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 a small number of cases rental payments also come 
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 
ongoing  base  essentiality,  military  deployments,  the  U.S. 
government’s commitment to fund the BAH, marketability/
attractiveness  of  the  on-base  housing  units  versus  off-base 
housing, 
environmental 
remediation,  utility  and  other  operating  costs  and  housing 
management.

Puerto Rico

Ambac has exposure to the Commonwealth of Puerto Rico (the  
"Commonwealth")  and 
instrumentalities  across  several 
different  issuing  entities.    Each  has  its  own  credit  risk  profile 
attributable  to,  as  applicable,  discrete  revenue  sources,  direct 
general obligation pledges and/or general obligation guarantees.  

its 

Fiscal Plans

On October 18, 2018, the Oversight Board certified the COFINA 
Fiscal Plan, which anticipated a resolution of the Commonwealth-
COFINA  dispute  litigated  in  adversary  proceeding  no.  1:17-
ap-00257. The COFINA Fiscal Plan reflects a sharing of the sales 
and  use  tax,  which  historically  has  provided  security  and  debt 
service  for  COFINA  bonds,  between  COFINA  and 
the 
Commonwealth (53.65% / 46.35% of the statutory pledged sales 
tax base amount, respectively, with first dollars going to COFINA) 
and the issuance of new COFINA bonds backed by the COFINA 
portion of these taxes.

On October 23, 2018, the Oversight Board certified a revised fiscal 
plan  for  the  Commonwealth  of  Puerto  Rico  (the  “Revised 
Commonwealth Fiscal Plan”).  Among other revisions from earlier 
certified  fiscal  plans  in  May  and  June  2018,  the  Revised 
Commonwealth Fiscal Plan projected a new cumulative 30-year 
surplus, post-measures and structural reforms, of approximately 
$19  billion,  which  is  net  of  30  years  of  expected  debt  service 
payments  on  the  new  COFINA  bonds  (as  described  below  and 
totaling  $32.3  billion).  The  new  surplus  projection  is  based  on 
various revised assumptions including a higher amount of federal 
disaster relief funding, 2018 actual tax collections and budgetary 
performance, and updated demographic data. As per the Revised 
Commonwealth Fiscal Plan, budget surpluses in the near-term are 
driven  by  assumptions  regarding  fiscal  measures  and  structural 
reforms, along with federal aid and enhanced revenue actuals. The 
Revised Commonwealth Fiscal Plan also shows long-term budget 
deficits  which  appear  to  be  driven  by  Oversight  Board  and/or 
Commonwealth  assumptions  regarding  healthcare  costs  that 
outpace Gross National Product ("GNP") growth, a lack of robust 
structural  reforms,  a  phase  out  of  disaster  relief  funding,  and 
declining  revenues  from  the  Act  154  excise  tax  paid  by 
multinationals operating in the Commonwealth.

However,  as  was  the  case  with  prior  fiscal  plans  for  the 
Commonwealth  of  Puerto  Rico,  the  Revised  Commonwealth 
Fiscal  Plan  lacks  a  high  degree  of  transparency  regarding  the 
underlying  data,  assumptions  and  rationales  supporting  those 
assumptions, making reconciliation and due diligence difficult. As 
a result, it is difficult to assess the possible impacts the changes 
and new assumptions may have on creditor outcomes or Ambac's 
financial condition, including liquidity, loss reserves and capital 
resources. 

It  is  also  unclear  if  and  when  the  Oversight  Board  will  certify 
revised fiscal plans for Puerto Rico Highways and Transportation 
Authority ("PRHTA") and other Puerto Rico instrumentalities that 
have debt outstanding that is insured by Ambac Assurance. It is 
unknown if and when other Puerto Rico instrumentalities, which 
have debt outstanding insured by Ambac Assurance, will be filed 
under  Title  III  and  what  effect  their  fiscal  plans  may  have  on 
Ambac's  financial  position.  No  assurances  can  be  given  that 
Ambac's  financial  profile  will  not  suffer  a  materially  negative 
impact as an ultimate result of the Revised Commonwealth Fiscal 

Plan or any future changes to the Revised Commonwealth Fiscal 
Plan  or  fiscal  plans  for  PRHTA  or  other  Puerto  Rico 
instrumentalities.

Federal Aid

In the October 23, 2018 Revised Commonwealth Fiscal Plan, the 
assumption for total projected federal disaster relief aid spending 
from fiscal years 2018 through 2032 is $74 billion. This consists 
of  $45.8  billion  in  projected  FEMA  Public Assistance  program 
spending  through  FEMA’s  Disaster  Relief  Fund  (DRF).  The 
Revised Commonwealth Fiscal Plan also projects $20 billion in 
spending  from  the  U.S.  Department  of  Housing  and  Urban 
Development’s Community Development Block Grant - Disaster 
Recovery (CDBG-DR) program, which has allocated aid funding 
to Puerto Rico for recovery and mitigation. In addition, the Revised 
Commonwealth Fiscal Plan projects $3.2 billion spending from 
the  FEMA Individual Assistance program , which provides support 
to individuals and families who have sustained uncovered losses 
due to disasters, and $5 billion in other federal funding. In addition, 
the Commonwealth of Puerto Rico continues to benefit from other 
federal  government  programs  for  infrastructure  improvement 
initiatives or recovery efforts.

While  these  federal  funds  are  expected  to  support  economic 
recovery and growth in Puerto Rico, there can be no assurances as 
to the certainty, timing, usage, efficacy or magnitude of benefits 
to creditor outcomes related to disaster aid and ensuing economic 
growth, if any.

Tax Reform

See Part I, Item 1A.  Risk Factors in this Form 10-K for a description 
of the risks to Ambac's Puerto Rico exposures due to tax reform.

Commonwealth Liquidity

The  Oversight  Board  announced  on  February  9,  2018  that  it 
retained Duff & Phelps, LLC to conduct an independent forensics 
analysis of the Commonwealth of Puerto Rico's government bank 
accounts.  It has been publicly disclosed that Duff & Phelps, LLC 
and  the  Puerto  Rico  Fiscal  Agency  and  Financial  Advisory 
Authority  ("FAFAA")  have  participated  in  discussions  to 
coordinate  this  process.  On  February,  15,  2019,  the  Oversight 
Board filed a complaint in the United States District Court for the 
District of Puerto Rico to compel the Puerto Rico Senate to provide 
its  bank  account  balances. The  Oversight  Board  stated  that  the 
Puerto Rico Senate bank account balance is a necessary element 
of  a  forensic  investigation  into  the  liquidity  of  the  Puerto  Rico 
government and its instrumentalities and entities, led by Duff & 
Phelps, LLC. The related Oversight Board press release disclosed 
that except for the Puerto Rico Senate, all 163 public entities which 
received requests for account balance and financial information 
have  responded  and  provided  data,  including  the  Puerto  Rico 
House of Representatives and the judicial branch. The progress of 
the analysis by Duff & Phelps, LLC and any related findings and 
financial information have not yet been made public. 

As of the December 31, 2018 bank account report published by  
FAFAA, the balances of bank accounts for various Puerto Rico 
government  entities  and  instrumentalities  totaled  $12.1  billion. 
According to the report, various account balances are considered 
restricted  for  different  government  entities  or  due  to  Title  III 
proceedings. However, it is unclear if these restricted designations 
are inaccurate or outdated since any legal analysis that may have 

| Ambac Financial Group, Inc.   38   2018 FORM 10-K |

been conducted to determine the restricted or unrestricted nature 
of funds in non-Treasury Single Account bank accounts has not 
been made publicly available. Consequently, the purported lack of 
access to restricted funds could limit the financial flexibility of the 
Commonwealth and its instrumentalities to provide essential and 
non-essential services. More generally, the lack of clear, consistent 
and  complete  information  regarding  account  balances  could 
further strain debt resolution timelines and potential severities for 
creditors, including Ambac.

As of February 1, 2019, the Treasury Single Account cash position, 
as  reported  by  the  Puerto  Rico Treasury  Department,  was  $4.2 
billion and above the $1.1 billion threshold to access Community 
Disaster Loan financing.  While details regarding final Community 
Disaster Loan terms are not known by Ambac, what is known is 
that the federal government has agreed to extend a credit line to 
the Commonwealth of Puerto Rico up to a maximum amount of 
$2.2 billion until March 31, 2020 to be used to meet any future 
liquidity  emergency  as  determined  by  the  Commonwealth  of 
Puerto Rico. However, in order to access the credit line, the fund 
balance in the Treasury Single Account needs to be less than $1.1 
billion.

COFINA Debt Restructuring

On October 19, 2018, following the certification of the COFINA 
Fiscal  Plan,  the  Oversight  Board  filed  the  COFINA  Plan  of 
Adjustment  ("POA")  and  Disclosure  Statement  as  part  of  the 
COFINA Title III case.  The Oversight Board also filed a Rule 9019 
Motion  in  the  Commonwealth  Title  III  case  to  approve  the 
settlement of the Commonwealth-COFINA dispute. The filing of 
the  COFINA  POA  and  Disclosure  Statement  as  well  as  the 
settlement  motion  followed  the  execution  of  a  settlement 
agreement between the Oversight Board and the COFINA Agent. 
That settlement agreement was based on the previously announced 
agreement in principle developed by the COFINA Agent and the 
Commonwealth  Agent.  The  COFINA  POA  was  based  on  the 
settlement agreement as well as the preliminary agreement among 
COFINA  bondholders  announced  August  8,  2018  and  the 
subsequent  Plan  Support Agreement  and  term  sheet  among  the 
Oversight  Board,  FAFAA,  COFINA,  bond  insurers  (including 
Ambac  Assurance),  as  well  as  certain  COFINA  and  General 
Obligation creditors. 

Under  the  COFINA  POA,  the  Pledged  Sales Tax  Base Amount 
("PSTBA) is split with 53.65% allocated on a first-dollars basis to 
COFINA through and including 2058 and 46.35% allocated to the 
Commonwealth. The COFINA POA contemplated exchanging all 
existing COFINA senior and subordinate bonds for cash as well 
as new COFINA current interest and capital appreciation bonds 
("new  COFINA  bonds").  The  cash  and  new  COFINA  bonds 
allocated  to  senior  bondholders  equaled  approximately  93% 
(considering  the  new  COFINA  bonds  at  par)  of  such  senior 
bondholders’ allowed claim, in the amount of the COFINA senior 
bond accreted value, as of, but not including, May 5, 2017 (the 
COFINA Title III Petition Date). 

Pursuant to the COFINA POA, each holder of Ambac Assurance-
insured senior COFINA bonds had the option to elect by January 
11, 2019 to either (i) commute their rights in respect of the Ambac 
Assurance  insurance  policy  associated  with  the  existing  senior 
COFINA  bonds,  which  bonds  would  be  discharged  and Ambac 
Assurance  policy  obligations  with  respect  thereto  would  be 

released, in exchange for new COFINA bonds, cash amounts to be 
paid by COFINA, plus additional cash consideration provided by 
Ambac Assurance  equal  to  5.25%  of  the  accreted  value  of  the 
Ambac  Assurance-insured  senior  COFINA  bonds  as  of  the 
COFINA  Petition  Date  or  (ii)  agree  to  deposit  their  Ambac 
Assurance-insured senior COFINA bonds into a a  trust in exchange 
for units issued by the trust (the "COFINA Class 2 Trust"), which 
trust would receive the new COFINA bonds and the cash amounts 
to be paid by COFINA that such bondholders would have otherwise 
received to the extent they had elected the recovery under clause 
(i) above (thereby entitling the COFINA Class 2 Trust to receive 
debt  service  payments  from  COFINA  with  respect  to  the  new 
COFINA  bonds  deposited  into  the  trust),  plus  any  accelerated 
policy  payments  (made  solely  at  Ambac  Assurance's  own 
discretion)  or  claim  payments  due  under  the  existing  Ambac 
Assurance  insurance  policy  for  the  deficiency  relating  to  the 
existing senior COFINA bonds at the relevant scheduled payment 
dates (2047 through 2054).  Any claims payable under the existing 
Ambac Assurance policy for the Ambac Assurance-insured senior 
COFINA bonds held in the trust will be reduced by all amounts 
distributed or deemed distributed from the trust to the holders of 
the trust units from the new COFINA bonds and cash as well as 
accelerated policy payments made by Ambac Assurance at its own 
discretion.  Ambac  makes  no  representation  and  can  give  no 
assurances that the new COFINA bonds or COFINA Class 2 Trust 
units,  both  of  which  are  not  insured  by Ambac Assurance,  will 
trade at par or any other price. Under the COFINA POA, Ambac 
Assurance-insured bondholders who did not affirmatively elect the 
trust option in clause (ii) above were deemed to have elected the 
commutation  option  described  in  clause  (i)  above.   As  of  the 
January  11,  2019  election  date,  74.9%  of  Ambac  Assurance-
insured senior COFINA bondholders, by measure of insured par, 
elected the commutation option or did not affirmatively elect to 
exchange their bonds for units of the COFINA Class 2 Trust.

On January 16-17, 2019, the hearings for the confirmation of the 
COFINA POA and the Commonwealth 9019 motion were held. 
On  February  4,  2019,  the  COFINA  Plan  of  Adjustment  was 
confirmed and the Commonwealth 9019 motion was approved by 
Judge Laura Taylor Swain of the U.S. District Court for the District 
of Puerto Rico. On February 12, 2019, the COFINA POA went 
effective,  concurrent  with  the  completion  of  the  commutation 
described  above.  Several  parties  are  presently  appealing  the 
confirmation of the POA. As a result, Ambac Assurance's insured 
COFINA  bond  exposure  decreased  by  $603  million  net  par  to 
approximately $202 million net par (a reduction of $5.5 billion of 
net  principal  and  interest  to  $1.8  billion  of  net  principal  and 
interest). Ambac Assurance's remaining policy obligation of $202 
million net par is an asset of the COFINA Class 2 Trust, which 
holds a ratable distribution of cash and new COFINA bonds, which 
can  be  used  to  partially  offset  Ambac’s  remaining  insurance 
liability.

Several parties are presently appealing the confirmation of the POA 
and  no  assurances  can  be  given  regarding  the  results  of  such 
appeals.  At  this  time,  it  is  unclear  what  impact  the  COFINA 
restructuring  will  have  on  the  prospective  recoveries  of Ambac 
Assurance's other  insured Puerto Rico instrumentalities.

Mediation

The status, timing and subject of any current or future mediation 
discussions have not been officially disclosed. No assurances can 

| Ambac Financial Group, Inc.   39   2018 FORM 10-K |

be  given  that  negotiations  will  be  successfully  concluded,  that 
Commonwealth, Oversight Board and creditor parties will reach 
definitive agreements on additional debt restructurings, that any 
additional  negotiated  transaction  debt  restructuring,  definitive 
agreement or Plan of Adjustment will be approved by the court 
and completed, or that any transaction or Plan of Adjustment will 
not  have  an  adverse  impact  on Ambac's  financial  conditions  or 
results.

Other Developments

On February 15, 2019, the United States Court of Appeals for the 
First Circuit issued an opinion in the consolidated appeals brought 
by certain parties who argued that the members of the Financial 
Oversight and Management Board for Puerto Rico (the "Oversight 
Board")  were  appointed  in  violation  of  the  U.S.  Constitution’s 
Appointments Clause. The First Circuit ruled that the Oversight 
Board members (other than the ex-officio Member) must be, and 
were not, appointed in compliance with the Appointments Clause. 
The First Circuit declined to dismiss the Oversight Board’s Title 
III  petitions  and  did  not  render  ineffective  any  otherwise  valid 
actions of the Oversight Board prior to the issuance of the ruling. 
The First Circuit stated that the ruling will not take effect for 90 
days, “so as to allow the President and the Senate to validate the 
currently  defective  appointments  or  reconstitute  the  Board  in 
accordance with the Appointments Clause." During the 90-day stay 
period, the Oversight Board may continue to operate as it had prior 
to the ruling. It is unclear how this ruling will impact, whether 
during or after such 90-day stay period, the restructuring process, 
mediation discussions and relevant litigation with respect to our 
Puerto Rico exposures.

Ambac Post-COFINA Title III Litigation Update 

Ambac Assurance is party to ten litigations related to its Puerto 
Rico  exposures,  and  is  currently  seeking  to  intervene  in  an 
eleventh. Three of these litigations are COFINA-related cases that 
have been, or will soon be, dismissed by operation of the COFINA 
Plan of Adjustment (“POA”) that was confirmed on February 4, 

2019, and became effective on February 12, 2019. Several parties 
are presently appealing the confirmation of the POA. A fourth is 
another  COFINA-related  case  that  had  been  stayed  pending 
resolution of an interpleader action related to COFINA funds, but 
which will be permitted to proceed by operation of the POA now 
that the interpleader action has been resolved. The two remaining 
active  litigations  are  an  appeal  relating  to  the  Puerto  Rico 
Highways and Transportation Authority pending before the United 
States  Court  of Appeals  for  the  First  Circuit,  and  an  adversary 
proceeding relating to the Puerto Rico Public Buildings Authority 
pending before the United States District Court for the District of 
Puerto Rico. The remainder of these litigations are stayed under 
Title III of PROMESA. Ambac is unable to predict when and how 
the issues raised in these cases (other than those already dismissed 
by operation of the POA) will be resolved. If Ambac Assurance is 
unsuccessful  in  any  of  these  proceedings,  Ambac’s  financial 
condition, including liquidity, loss reserves and capital resources 
may suffer a material negative impact.

Refer  to  Note  16.  Commitments  and  Contingencies  to  the 
Consolidated Financial Statements, included in Part II, Item 8 in 
this Form 10-K, for further information about Ambac's litigation 
relating to Puerto Rico.

Summary

Ambac  has  considered  these  developments  and  other  factors  in 
evaluating its Puerto Rico loss reserves.  During the year ended 
December 31, 2018, Ambac had incurred losses associated with 
its  Domestic  Public  Finance  insured  portfolio  of  $36.7  million, 
which was significantly impacted by the continued uncertainty and 
volatility  of  the  situation  in  Puerto  Rico.    While  management 
believes  its  reserves  are  adequate  to  cover  losses  in  its  Public 
Finance insured portfolio, there can be no assurance that Ambac 
may not incur additional losses in the future, particularly given the 
developing economic, political, and legal circumstances in Puerto 
Rico.  Such additional losses may have a material adverse effect 
on Ambac’s results of operations and financial condition.

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    governor,  on  December  1,  2015.   A  description  of Ambac's  legal  challenge  is  provided  in  Note  16.  Commitments  and

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.   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 as opposed to the current 

accreted value of the bonds.  Accretion of the capital appreciation bonds would increase the related net par by $753 at December 31, 2018.

(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 bonds does not represent the accreted amount as noted in footnote (2) but rather the amount due at respective maturity dates. 

(4) 

In addition to ever-to-date net claims paid, Ambac made net claim payments of $25 during January 2019.

(5)  Commonly known as "clawback" provision pursuant to Section 8 of Article VI of the Constitution of the Commonwealth of Puerto Rico. Under this 
provision, in case the available revenues (the Spanish version uses the term “resources”)  including surplus for any fiscal year are insufficient to meet the 
appropriations made for that year, interest on the public debt and amortization thereof shall first be paid, and other disbursements shall thereafter be made 
in accordance with the order of priorities established by law.  These exposures are also subject to Act No. 5-2017, as amended, also known as the Financial 
Emergency and Fiscal Responsibility Act of 2017, which declares an emergency period that has been subsequently re-extended until June 30, 2019 from 
its prior December 31, 2018 deadline.   Pursuant to Act 5-2017, all executive orders issued under Act No. 21-2016 (as amended, known as the Puerto Rico 
Emergency Moratorium and Financial Rehabilitation Act), shall continue in full force and effect until amended, rescinded or superseded.

(6)  Certain Pledged Revenues for Highways and Transportation Revenue Bonds such as Toll Revenues and Investment Earnings are not subject to the Priority 

Debt Provision. 

(7)  Payable from and secured by proceeds from a federal excise tax imposed on all items produced in Puerto Rico and sold on the mainland of the United 

States.  Currently, rum is the only product from Puerto Rico subject to this federal excise tax.

(8)  Net Par and Interest Outstanding excludes the effects of a 10% current interest rate on $60 net par of PR Public Building Authority ("PBA") bonds with 
a maturity date of July 1, 2035, resulting from the absence of a remarketing. Should a remarketing not occur before the maturity of the bonds, the Net Par 
and Interest Outstanding for PBA exposure would increase by $44.7.

(9)  As mentioned above, the COFINA POA was confirmed by the United States District Court for the District of Puerto Rico on February 4, 2019 and became 
effective on February 12, 2019. The POA and certain related commutation transactions resulted in a reduction of Ambac Assurance's insured net par 
exposure to COFINA by approximately 75% or $603 to $202 (net par and interest reduction of $5,525 to $1,797).

effective on February 12, 2019. The POA and certain related commutation transactions resulted in a reduction of Ambac Assurance's insured net par 
exposure to COFINA by approximately 75% or $603 to $202.

U.S. Structured Finance Portfolio 

Ambac’s portfolio of U.S. structured finance exposures is $9,947 
million, representing 21% of Ambac’s net par outstanding as of 
December 31,  2018,  and  a  28%  reduction  from  the  amount 
outstanding at December 31, 2017. This reduction in exposure was 
primarily  related  to  residential  mortgage-backed  securities 
("RMBS")  policies,  which    was  attributable  to  continued 
prepayments and claims presented on insured RMBS bonds as well 
as  commutations  and  clean-up  calls,  both  negotiated  and  non-
negotiated, of certain RMBS transactions with less than 10% of 
their original mortgage pool balances remaining. In addition, the 
refinancing  of  various  investor-owned  utility  exposures  and 
commutation  and  reinsurance  of  other  structured  finance 
transactions contributed to this overall reduction in U.S. structured 
finance exposure. 

Current  insured  exposures  include  securitizations  of  mortgage 
loans, home equity loans, student loans, leases, operating assets, 
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.  Additionally, 
Ambac’s structured finance insured portfolio includes secured and 
unsecured debt issued by investor-owned utilities.  It also includes 
structured insurance transactions, including transactions providing 
insurance on the notes of trusts that were established in connection 
with the reinsurance of defined blocks of life insurance and that 
were  used  to  fund  regulatory  reserves  associated  with  level 

premium  term  life  insurance  policies  (commonly  referred  to  as 
Regulation XXX reserves).

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, 2018. 

Structured finance securitization 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. 

Securitized  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 

| Ambac Financial Group, Inc.   42   2018 FORM 10-K |

to  bankruptcy  or 

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. 

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 lien mortgages.  
Ambac's total net par exposure to RMBS at December 31, 2018 
was  approximately  $5.5  billion  ($3.2  billion,  $2.1  billion,  $0.2 
billion are first lien, second lien and other respectively), a decrease 
of 24% during 2018.  At December 31, 2018, 85% of RMBS net 
par exposure relates to securitizations issued during 2005 through 
2007.

International Finance Insured Portfolio 

Ambac’s  portfolio  of  international  finance  insured  exposures  is 
$13,538 million, representing 29% of Ambac’s net par outstanding 
as of December 31, 2018 and a 19% reduction from the amount 
outstanding at December 31, 2017. This reduction in exposure was 
primarily the result of policy terminations within investor-owned 
utilities and asset-backed securities as well as a strengthening of 
the  US  dollar. Ambac’s  international  finance  insured  exposures 
include a wide array of obligations in the international markets, 
including  infrastructure  financings,  asset-securitizations,  utility 

obligations, whole business securitizations (e.g., securitizations of 
substantially all of the operating assets of a corporation) and sub-
sovereign  credit.  Ambac  has  no  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, 2018.

When  underwriting  transactions  in  the  international  markets, 
Ambac  considered  the  specific  risks  related  to  the  particular 

| Ambac Financial Group, Inc.   43   2018 FORM 10-K |

country and region that could impact the credit of the issuer. These 
risks include the legal and political environment, capital markets 
dynamics, foreign exchange issues and the degree of governmental 
support. Ambac continues to assess these risks through its ongoing 
risk management. 

Agreement") setting out the terms of a transition period to apply 
to the UK between March 29, 2019 and December 31, 2020. The 
effect of the withdrawal agreement, if ratified, will be to retain the 
rights  and  obligations  between  the  UK  and  the  EU  within  this 
transition period.

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  $13,193  million  net  par  outstanding  in  those  markets  at 
December 31, 2018, of which $900 million relates to a structured 
insurance US risk transaction. The portfolio of insured exposures 
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. 

Other European Union Exposures (“EU”)

Ambac's  international  net  par  exposures  are  principally  in  the 
United  Kingdom  ($10,965  million);  however,  we  also  have 
exposures with credit risk based in various other EU member states, 
including Austria,  France,  Germany  and  Italy  ($1,564  million).  
Italy,  with  net  par  exposures  of  $811  million,  in  particular  has 
experienced economic, fiscal and political strains since the 2008 
global  financial  crisis  such  that  the  likelihood  of  default  on  an 
insured  sub-sovereign  obligation  in  that  country  is  higher  than 
when the policy was underwritten.  

Ambac does not guarantee any sovereign bonds of the above EU 
countries. 

Brexit:

In  March  2017  the  UK  government  gave  the  European  Union 
(“EU”) formal notification of its intention to leave the EU with the 
expectation of formal withdrawal two years later on March  29, 
2019 (“Brexit”).  In November 2018 the UK Government and EU 
agreed  upon  the  terms  of  a  legal  binding  treaty  ("Withdrawal 

The withdrawal agreement remains subject to ratification by the 
UK Parliament, EU Council and EU Parliament. If the withdrawal 
agreement is not ratified and no transitional arrangement is put into 
place,  Brexit  may  mean  that  the  activities  in  the  EEA  of  UK 
passporting insurers may become unlawful on March 29, 2019. 
They may lose their legal authorization to serve clients who benefit 
from policies issued by a UK incorporated insurer under freedom 
of services and freedom of establishment passporting rights (and 
thereby maybe unable to legally collect premiums or pay claims) 
and  if  they  have  branches  in  EEA  Member  States  they  may  be 
legally  obliged  to  close  them  down  and  no  longer  be  legally 
represented in those jurisdictions. 

the  recommendation 

However  on  February  19,  2019,  the  European  Insurance  and 
Occupational  Pensions  Authority  (“EIOPA”)  made  a  series  of 
recommendations to EU insurance regulators in light of Brexit.  
These  recommendations 
that 
include 
regulatory  authorities  apply  legal  frameworks  that  facilitate  the

Geographic Area 

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, 
2018 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 
prepayments over the remaining life of the insured obligation.

Ratings Distribution 

The following tables provide a rating distribution of existing net 
par  outstanding  based  upon  internal  Ambac  credit  ratings  at 
December 31, 2018 and 2017 and a distribution by bond type of 
Ambac's  below  investment  grade  ("BIG")  net  par  exposures  at 
December 31, 2018 and 2017. BIG is defined as those exposures 
with an internal credit rating below BBB-: 

Note:  AAA is less than 1% in both periods.

Internal credit ratings are provided solely to indicate the underlying 
credit quality of guaranteed obligations based on the view of Ambac 
Assurance, and for Ambac UK related transactions, based on the view 
of Ambac UK. In cases where Ambac Assurance or Ambac UK has

(1)  Tax-backed  includes  $1,735  and  $1,802  of  Puerto  Rico  net  par  at 
December  31,  2018  and  2017,  respectively.    General  obligation 
includes $145 and $166 of Puerto Rico net par at December 31, 2018 
and  2017,  respectively.    Puerto  Rico  net  par  outstanding  includes 
capital appreciation bonds which are reported at the par amount at 
the time of issuance of the related insurance policy as opposed to the 
current accreted value of the bonds.  As mentioned above the COFINA 
POA was confirmed by the United States District Court for the District 
of Puerto Rico on February 4, 2019 and became effective on February 
12,  2019.  The  POA  and  certain  related  commutation  transactions 
resulted in a reduction of Ambac Assurance's insured net par exposure 
to COFINA by approximately 75% or $603 to $202 (included in tax-
backed).

(2) 

Includes $314 and $317 of military housing net par at December 31, 
2018 and 2017, respectively.

The decrease in below investment grade exposures is primarily 
due to reductions to residential mortgage-backed securities during 
the  year  as  a  result  of  prepayments  by  issuers,  clean-up  calls, 
commutations and claims presented to Ambac Assurance.  Despite 
the  decrease  in  below  investment  grade  net  par,  such  exposure 
remained  flat  in  relative  proportion  to  the  aggregate  insured 
portfolio of 22% at December 31, 2018 and December 31, 2017.  
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

on our financial condition.

Ceded Reinsurance

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  $114.3  million  from  its  reinsurers  at 
December 31,  2018.  As  of  December 31,  2018,  the  aggregate 
amount of insured par ceded by Ambac Assurance to reinsurers 
under reinsurance agreements was $5,128 million, with the largest 
reinsurer  accounting  for  $3,076  million  or  5.9%  of  gross  par 
outstanding at December 31, 2018.

Rehabilitation Exit Transactions. On February 12, 2018, Ambac 
Assurance executed the following Rehabilitation Exit Transactions 
(as  more  fully  discussed  in  Note  1.  Background  and  Business 
Description  in  the  Notes  to  Consolidated  Financial  Statements 
included in this Annual Report:

(other 

•  The  Second  Amended  Plan  of  Rehabilitation  became

which  provided  holders  of  beneficial  interests  in  Deferred 
Amounts

Assurance)  a  total  effective  consideration  package,  in  full 
satisfaction and discharge of each $1.00 of Deferred Amounts 
(including  accretion),  of  (i)  $0.40  in  cash,  (ii)  $0.41  in 
principal  amount  of  new  Secured  Notes  and  (iii) $0.125 
currently outstanding surplus notes (from certain holders of 

| Ambac Financial Group, Inc.   47   2018 FORM 10-K |

surplus  notes).    Such  consideration  package  provided  a 
discount  of  $0.065  (set  first  against  accretion  of  Deferred 
Amounts).  Ambac  received  $0.91  in  principal  amount  of 
Secured Notes for each $1.00 of Deferred Amounts (including 
accretion) that it held, and provided a $0.09 discount in full 
satisfaction  and  discharge  of  its  Deferred Amount  claims. 
This transaction was accounted for as an extinguishment of 
Deferred Amounts and the discount of approximately $288 
million from the settlement was reflected as a benefit to loss 
and  loss  expenses  in  the  Consolidated  Statements  of 
Comprehensive Income (Loss) in 2018.  In connection with 
these transactions, Ambac Assurance received $196 million 
of  principal  and  accrued  and  unpaid  interest  on  general 
account surplus notes.  Ambac Assurance recognized a gain 
on the extinguishment of these surplus notes of $3 million. 

•  Exchanges were consummated pursuant to which holders of 
surplus notes received the same effective package as holders 
of  beneficial  interests  in  Deferred  Amounts,  including  a 
discount of $0.065 for each $1.00 of principal amount and 
accrued  and  unpaid  interest  on  the  surplus  notes  tendered.  
These exchanges resulted in Ambac Assurance's cancellation 
of $809.5 million of principal and accrued and unpaid interest 
of  general  account  surplus  notes.  These  exchanges  were 
accounted for as a debt modification since the creditors before 
and after the discount remained the same and the change in 
the  terms  were  not  considered  substantial.  A  substantial 
change is considered to be a change in cash flows of equal to 
or greater than 10% as a result of the modification of terms. 
As  the  change  in  cash  flows  was  less  than  10%,  debt 
modification  accounting  was  appropriate.  Under  debt 
modification accounting, no gain or loss was recorded, and a 
new effective interest rate was established based on the cash 
flows of the Ambac Note, which secures the Secured Notes 
issued. 

•  Ambac Assurance issued $240 million of new debt secured 
by  certain  of  Ambac  Assurance’s  rights  to  RMBS  R&W 
subrogation recoveries above $1.6 billion ("Tier 2 Notes").  
The proceeds received from this issuance were used to help 
fund the cash portion of the consideration paid pursuant to 
the Second Amended Plan of Rehabilitation and exchanges 
noted  above.  Refer  to  Note  13.  Long-term  Debt  to  the 
Consolidated  Financial  Statements, 
the 
Company’s Annual Report on Form 10-K for the year ended 
December 31, 2018.

•  Ambac  incurred  operating  expenses  for  the  year  ended  
December 31, 2018, including for AAC and OCI financial 
advisors, of approximately $17 million. 

In order to execute these transactions, Ambac established a special 
purpose  entity, Ambac  LSNI,  LLC,  for  the  sole  purpose  of  the 
issuance  of  $2,154  million  of  Secured  Notes,  of  which Ambac 
Assurance  received  $644  million  and  Ambac  received  $125 
million.    Ambac  does  not  consolidate  Ambac  LSNI,  LLC; 
therefore, the full amount of the debt is included in long term debt 
and Secured Notes currently held by Ambac and Ambac Assurance 
are included in invested assets on the consolidated balance sheet.

Net Premiums Earned.  Net premiums earned primarily represent 
the  amortization  into  income  of  insurance  premiums.  Net 
premiums earned for the year ended December 31, 2018, decreased 
by $64 million or 36.6% as compared to net premiums earned for 

the year ended December 31, 2017.  Net premiums earned for the 
year ended December 31, 2017, decreased by $22 million or 11.2%
as  compared  to  net  premiums  earned  for  the  year  ended 
December 31, 2016.  

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 $2 million, $1 million, and $8 million, for the years 
ended December 31, 2018, 2017 and 2016, 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.  

•  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.

•  New  ceded    reinsurance  of  insurance  risk  which  reduces 
normal net premiums earned over the remaining period of the 
related policies.

•  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, 
including a breakdown of net premiums earned by market:

from  holdings  of  Ambac-insured  securities  for  the  periods 
presented have primarily been driven by RMBS and Puerto Rico 
bonds  insured  by Ambac Assurance  and,  in  2018,  the  Secured 
Notes issued by Ambac LSNI.  Also, included in net investment 
income are net gains and (losses) on pooled investment funds and 
certain other investments that are classified as trading securities 
with  changes  in  fair  value  recognized  in  earnings.    Trading 
securities are included in Other investments on the Consolidated 
Balance  Sheets.    Most  trading  securities  are  in  the Ambac  UK

asset  classes  including  equities,  hedge  funds,  loans,  insurance-

Net investment income decreased $88 million for the year ended 
December 31, 2018 compared to 2017 and increased $48 million 
for the year ended December 31, 2017 compared to 2016.  Net 
investment  income  for  the  year  ended  December  31,  2018  was  
significantly  impacted  by  the  Rehabilitation  Exit  Transactions 
which  reduced  the  overall  size  of  the  investment  portfolio  as  a 
result of:  (i) net cash paid on the transactions and (ii) the decline 
in carrying value of investments in Ambac-insured RMBS due to 
the  settlement  of  embedded  deferred  claims,  partially  offset  by 
Secured Notes received.  Primarily as a result of these changes in 
the portfolio, 2018 investment income from all securities available 
for sale declined compared to 2017.  These declines were partially 
offset by income earned in 2018 on Secured Notes.  The year ended 
December  31,  2018  also  included  higher  income  on  Ambac-
insured Puerto Rico bonds due to Ambac's higher average holdings 
as most of these bonds were purchased over the course of 2017.  
The  decline  in  net  performance  on  trading  securities  in  2018 
compared to 2017 arose primarily from losses on Ambac UK  hedge 
fund and equity index fund investments.  Other asset classes held 
in trading also underperformed relative to 2017.

The increase in income in 2017 was due to a greater allocation to 
higher-yielding Ambac-insured securities, partially offset by lower 
net gains on trading securities.  Investment income increased on 
Ambac-insured RMBS securities driven primarily by reprojected 
cash flows in the fourth quarter of 2017 reflecting the anticipated  
Rehabilitation  Exit  Transactions.    Income  from Ambac-insured 
securities also reflects additional purchases of Puerto Rico bonds 
over the course of 2017 and additional purchases by Ambac UK 
of its insured bonds.  Net income from trading securities declined 
in 2017 primarily due to catastrophe-driven losses on insurance-
linked securities and lower returns on loans and equities, net of 
foreign exchange effects.  The strengthening British pound sterling  

in 2017 partially offset strong equity market gains in Ambac UK's 
pooled  fund  holdings  compared  to  2016,  when  results  were 
favorably impacted by the declining British pound.      

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,  2018,  2017  and  2016  related  to  credit  losses  on 
certain Ambac-wrapped securities stemming primarily from cash 
flow  projections  and  to  the  company’s  intent  to  sell  certain 
securities  that  were  in  an  unrealized  loss  position  as  of  the 
impairment  evaluation  dates.  During  the  Segregated  Account 
Rehabilitation Proceedings (as defined in Note 1. Background and 
Business  Description  in  the  Notes  to  Consolidated  Financial 
Statements included in this  Report on Form 10-K), changes in the 
estimated timing of claim payments resulted in adverse changes 
in  projected  cash  flows  on  certain  impaired  Ambac-wrapped 
securities. Ambac  estimated  the  timing  of  such  claim  payment 
receipts, but the actual timing of such payments were at the sole 
discretion of the Rehabilitator  (as defined in Note 1. Background 
and Business Description in the Notes to Consolidated Financial 
Statements included in this  Report on Form 10-K).  Refer to Note 
1.  Background  and  Business  Description  to  the  Consolidated 
Financial  Statements  for  more  information  on  the  Segregated 
Account and the Segregated Account Rehabilitation Proceedings.   

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.

The interest rate derivatives portfolio is positioned to benefit from 
rising  rates  as  a  partial  economic  hedge  against  interest  rate 
exposure  in  the  financial  guarantee  and  investment  portfolios.  
Results  in  Net  gain  (loss)  on  interest  rate  derivatives  generally 
reflect mark-to-market gains (losses) in the portfolio caused by 
increases (declines) 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  gains  on  interest  rate  derivatives  for  the  year  ended 
December 31, 2018 were $7 million, compared to the net gain 
of $60 million for the year ended December 31, 2017.   While 
interest rates rose in both 2018 and 2017, overall gains for 
2018 were lower as a result of $42 million of gains realized 
in 2017 on certain swaps commuted with a structured finance 
vehicle,  higher  carrying  costs  in  2018  and  an  increase  in 
counterparty  credit  adjustments  on  certain  uncollateralized 
derivative assets compared to decreases in 2017.    

•  The  interest  rate  derivatives  loss  for  2016  was  primarily 
driven by the impact of 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. 

The  fair  value  of  derivatives  include  valuation  adjustments  to 
reflect Ambac’s own credit risk and counterparty credit risk. Within 
the interest rate 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  the  Ambac  CVA  in  the  valuation  of  interest  rate 
derivatives  contributed  (losses)  gains  of  $(34)  million  in  2016. 
Counterparty  credit  adjustments  are  generally  applicable  for 
uncollateralized  derivative  assets  that  may  not  be  offset  by 

The net gain/(loss) from change in fair value of credit derivatives 
for the year ended December 31, 2018 was less than $(1) million, 
as compared to the gains of $16 million and $20 million for the 
years ended December 31, 2017 and 2016, respectively.   The gain 
for 2017 was mainly due to the reversal of unrealized losses from 
swap terminations, including the remaining adversely classified 
credit in the portfolio, $1.0 million of termination fees received 
and reference obligation price improvements. 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. 

Net  Realized  Gains  (Losses)  on  Extinguishment  of  Debt.  Net 
realized gains on extinguishment of debt was $3 million for the 
year ended December 31, 2018, compared to gains of $5 million
and $5 million for the years ended December 31, 2017 and 2016, 
respectively.   The  gains  for  the  year  ended  December 31,  2018 
related to surplus notes received by Ambac Assurance in settlement 
of Deferred Amounts held in its investment portfolio in connection 
with the Rehabilitation Exit Transactions.  The gains for the years 
ended  December  31,  2017  and  2016  included  gains  from  the 
settlements of purchased surplus notes below their carrying values 
and  gains  from  the  settlements  of  certain  residual  obligations 
related to previously called surplus notes. 

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 VIEs during the periods reported.  Generally, the 
Company’s consolidated VIEs are entities for which Ambac has 
provided financial guarantees on all of or a portion of its assets or 
liabilities.  In consolidation, 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. 
Additionally, terminations or other changes to Ambac's financial 
guarantee  insurance  policies  that  impact  projected  cash  flows 
between a consolidated VIE and Ambac could result in gains or 
losses, even if such policy changes do not result in deconsolidation 
of the VIE.

Income  (loss)  on  variable  interest  entities  was  $3  million,  $20 
million and $(14) million for the years ended December 31, 2018, 
2017 and 2016, respectively. 

| Ambac Financial Group, Inc.   50   2018 FORM 10-K |

•  Income  on  variable  interest  entities  for  the  year  ended 
December  31,  2018  included  gains  on  deconsolidation  of 
VIEs as a result of financial guarantee policy terminations 
and discount accretion on remaining VIE net assets. 

•  Income  on  variable  interest  entities  for  the  year  ended 
December 31, 2017 is due primarily to a higher net asset value 
of a VIE related to an increase in projected financial guarantee 
insurance premiums.  

•  Loss  on  variable  interest  entities  for  the  year  ended 
December 31, 2016 reflected a decrease in the fair value of 
net assets primarily due to the decrease in the CVA applied 
to  certain  VIE  note  liabilities  that  included  significant 
projected  financial  guarantee  claims.      Other  than  those 
transactions 
financial 
guarantee claims, the fair value of VIE net assets increased

Losses and Loss Expenses (Benefit).  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 (as defined 
in Note 1. Background and Business Description in the Notes to 
Consolidated  Financial  Statements  included  in  this    Report  on 
Form  10-K)  pursuant  to  the  Segregated Account  Rehabilitation 
Plan (as defined in Note 1. Background and Business Description 
in the Notes to Consolidated Financial Statements included in this  
Report on Form 10-K) that were discharged on February 12, 2018. 

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  estimate  an  RMBS  R&W  subrogation 
recovery  where  its  sole  claim  is  for  fraudulent  inducement. 
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 R&W subrogation recoveries, net of 
reinsurance, of $1.744 billion and $1.807 billion at December 31, 
2018 and 2017, 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  RMBS  R&W 
subrogation recoveries.

Losses and loss expenses (benefit) for the year ended December

(1)  The  loss  and  loss  expense  (benefit)  associated  with  changes  in 
estimated representation and warranties for the year ended December 
31, 2018, 2017 and 2016 was $62 million, $72 million, and $(71)

million  for  the  year  ended  December  31,  2018,  2017  and  2016, 
respectively.  

Losses and loss expenses for 2018 were driven by the following:

•  Discount  achieved  pursuant  to  the  Rehabilitation  Exit 
Transactions, partially offset by interest on Deferred Amounts 
through the Rehabilitation Exit Transactions effective date;

•  Higher  projected  losses  in  domestic  public  finance  largely 
driven  by  Military  Housing  loss  expenses  incurred  and 
adverse  development  on  a  certain  general  obligation  and 
transportation risks;

•  Favorable  RMBS  credit  development,  partially  offset  by  a

Losses and loss expenses for 2017 were driven by the following:

•  Higher  projected  losses  in  domestic  public  finance  largely 
driven  by  adverse  development  on  Puerto  Rico  and  the  
Military Housing sector;

•  Interest on Deferred Amounts;

•  Lower projected losses in the Ambac UK portfolio primarily 
due  to  the  confidential  settlement  of  litigation  brought  by 
Ambac UK in the name of Ballantyne against JPMIM and 
from activities executed by the Ballantyne trust that indirectly 
reduced future expected claims on the Ambac insured notes;

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

•  Lower  projected  losses  in  the  RMBS  portfolio  due  to 
improved deal performance, higher RMBS R&W subrogation 
recoveries  and  a  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; 

•  Higher  projected  losses  in  domestic  public  finance  largely 

driven by adverse development in Puerto Rico;

•  Interest on Deferred Amounts;

•  Increased  projected  losses  in  the  Ambac  UK  portfolio 
primarily  due  to  foreign  exchange  losses  of  $78  million 
partially offset by lower interest rates.

through to the balance sheet date in accordance with the amended 
Segregated Account  Rehabilitation  Plan  and  associated  rules  and 
guidelines.  Claims  recorded  exclude  interest  accrued  on  Deferred 
Amounts.  On February 12, 2018, the rehabilitation of the Segregated 
Account was concluded and all Deferred Amounts, including accrued 
interest,  were  settled.  Subsequent  to  the  Rehabilitation  Exit 
Transactions, claims are paid in full.

(2)  Claims recorded includes claims paid on Puerto Rico policies of $157, 
$143 and $63 for the years ended December 31, 2018, 2017 and 2016, 
respectively.

(3)  Subrogation received declined due to the continuous runoff of the 
RMBS insured portfolio and the impact of higher interest rates on 
excess spread.  

(4)  Subrogation received for the year ended December 31, 2017 includes 
$50 ($50 gross of reinsurance) related to a reimbursement of claims 
due to a mortgage insurance settlement.  Subrogation received for 
the  year  ended  December  31,  2016  includes  $993  ($995  gross  of 
reinsurance)  received  from  the  settlement  of  representation  and

respectively, and expenses related to the AMPS Exchange of $8, $0 
and  $0  for  the  years  ended  December  31,  2018,  2017  and  2016, 
respectively.

Gross operating expenses for the year ended December 31, 2018
are $111 million, a decrease of $11 million from gross operating 
expenses for the year ended December 31, 2017.  The decrease 
was primarily due to the following:

•  Lower non-compensation costs primarily due to  a $21 million 
reduction in legal, consulting and advisory costs related to the 
exit from rehabilitation of the Segregated Account, of which 
$5 million relates to advisory services provided for the benefit 
of OCI, partially offset by costs of  $8 million associated with 
the August 2018 AMPS Exchange. 

•  Slightly higher compensation costs related to higher incentive 
compensation  costs  driven  by  (i)  an  improvement  in 
performance metrics; (ii) granting of incentive awards related 
to  the  Rehabilitation  Exit Transactions;  (iii)    the  timing  of 
recognition  of  equity  based  compensation  in  lieu  of  cash 
bonuses;  and  (iv)  amounts  related  to  the  settlement  of  a 
previously granted performance based restricted stock unit 
award  issued  to  the  former  CEO  that  vested  upon  the 
Segregated Account's exit from rehabilitation;  partially offset 
by  lower  salaries  and  post  employment  costs,  including 
severance as a result of reduced headcount.   

Gross operating expenses for the year ended December 31, 2017
were $122 million, an increase of $9 million from gross operating 
expenses for the year ended December 31, 2016.  The increase was 
primarily due to the following:

•  Higher  non-compensation  costs  primarily  due  to  (i)  $22 
million  incremental  legal,  consulting  and  advisory  costs 
related to the Rehabilitation Exit Transactions, (ii) $5 million 
incremental  OCI  legal  and  consulting  costs  primarily  in 
connection with the Rehabilitation Exit Transactions, and (iii) 
$4 million increase in state taxes primarily due to a $2 million 
reduction of accrued state income taxes in 2016 due to the 
final  resolution  of  state  insurance  tax  assessments.   These 
increased  costs  were  partially  offset  by  (i)  a  reduction  in 
litigation contingencies of $8 million and (ii) a reduction in 
costs associated with stockholder activism of $6 million in 
2016.

•  Lower  compensation  costs  related 

to  salaries,  post 
employment  costs,  including  severance,  partially  offset  by 
increased long term incentive compensation costs due to an 
in  performance  factors.  Although  post-
improvement 
employment costs have decreased from 2016, the Company 
reduced headcount in 2017 resulting in severance charges.  

| Ambac Financial Group, Inc.   52   2018 FORM 10-K |

These charges are lower than prior year due to 2016 including 
severance costs related to the former CEO.

With the conclusion of the Segregated Account rehabilitation, the 
duties of the Wisconsin Insurance Commissioner as rehabilitator 
of  the  Segregated  Account  have  been  discharged.    Legal  and 
consulting services provided for the benefit of OCI amounted to 
$7  million,  $12  million  and  $6  million  for  the  years  ended 
December 31, 2018, 2017 and 2016, respectively.   Subsequent to 
the  Segregated  Account's  exit  from  rehabilitation,  advisory 
services for the benefit of OCI will continue, but at a reduced level.

Interest  Expense.    Interest  expense  primarily  includes  accrued 
interest on  the Ambac Note, Tier 2 Notes, secured borrowing notes 
and  surplus  notes  issued  by  Ambac  Assurance.    Additionally, 
interest  expense  includes  discount  accretion  when  the  debt 
instrument carrying value is at a discount to par.

million, respectively, for the years ended December 31, 2018, 2017 
and 2016.  

The increase in interest expense for the year ended December 31, 
2018,  compared  to  2017  primarily  reflects  the  impact  of  the 
Rehabilitation Exit Transactions that resulted in the issuance of the 
Ambac Note and Tier 2 Notes partially offset by reduced surplus 
note balances.  Surplus notes outstanding increased in the second 
half of 2018 due to surplus notes issued by Ambac Assurance in 
connection with the AMPS Exchange and Ambac sales of notes to 
the market.  On June 22, 2018, the secured borrowing notes were 
fully  redeemed.    Refer  to  Note  13.  Long-term  Debt  to  the 
Consolidated Financial Statements for further information on the 
Ambac Note and Tier 2 Notes.

The decrease in interest expense for the year ended December 31, 
2017,  compared  to  2016  primarily  results  from  the  impact  of 
purchases of surplus notes during the first half of 2017 and reduced 
debt balances resulting from amortization of the secured borrowing 
notes outstanding.  The decrease in interest expense was partially 
offset  by  the  impact  of  applying  the  level  yield  method  as  the 
discount to the face value of the surplus note accretes over time. 
The year ended December 31, 2017 also includes commitment fees 
incurred for the Tier 2 Financing as part of the Rehabilitation Exit 
Transactions.  Refer  to  Note  1.  Background  and  Business 
Description  to  the  Consolidated  Financial  Statements  for 
information relating to the Rehabilitation Exit Transactions and 
Tier 2 Financing.

Surplus note principal and interest payments require the approval 
of  OCI.  Except  for  a  one-time  payment  of  approximately  six 

months of interest on the outstanding surplus notes (excluding the 
junior  surplus  notes)  immediately  after  the  Rehabilitation  Exit 
Transactions, annually from  2011 through 2018,  OCI  issued its 
disapproval of the requests of Ambac Assurance to pay the full 
interest  on  outstanding  surplus  notes  issued  by Ambac  on  the 
annual  scheduled  interest  payment  date  of  June 7th.  Ambac 
Assurance has not requested to pay interest on any junior surplus 
notes since their issuance. The interest on 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 and unpaid interest for surplus 
notes and junior surplus notes outstanding to third parties were 
$262 million and $122 million, respectively, at December 31, 2018.

Provision for Income Taxes. The provision for income taxes for 
the year ended December 31, 2018, 2017 and 2016 was $5 million, 
$44  million,  and  $31  million,  respectively.    The  income  tax 
provision for  these periods included AMT of $(2) million, $(29) 
million, $4 million, respectively. The income tax for the year ended 
December 31, 2018, and 2017 reflect  discrete benefit of $2 million, 
and a discrete estimated cost of $2 million, respectively, resulting 
from the TCJA, further described in  Note 14. Income Taxes. The 
income tax for the year ended December 31, 2018, 2017 and 2016, 
includes provisions for income tax due in respect of Ambac UK 
of $5 million, $72 million, and  $26 million, respectively.  Ambac 
UK  fully  utilized  operating  losses  brought  forward  from  prior 
periods in the first quarter of 2016, resulting in income tax being 
payable.  

At  December 31,  2018  the  Company  had  $3.5  billion  of  U.S. 
Federal net ordinary operating loss carryforwards, including $1.3 
billion  at  Ambac  Financial  Group  and  $2.2  billion  at  Ambac 
Assurance.

LIQUIDITY AND CAPITAL RESOURCES

Ambac  Financial  Group,  Inc.  Liquidity. Ambac’s  liquidity  is 
dependent on its  cash, investments and receivables totaling  $455 
million as of December 31, 2018 and expense sharing and other 
arrangements with Ambac Assurance. 

Ambac's  investments  include  securities  directly  and  indirectly 
issued by and/or insured by Ambac Assurance some of which are 
eliminated in consolidation.  Securities issued or insured by Ambac 
Assurance are generally less liquid than investment grade and other 
traded investments.

Pursuant to the amended and restated tax sharing agreement among 
Ambac, Ambac Assurance  and  certain  affiliates  (the  "Amended 
TSA"), Ambac Assurance is required to make payments ("tolling 
payments") to Ambac with respect to the utilization of net operating 
loss carry-forwards (“NOLs”). Ambac has accrued $30 million of 
tolling  payments  based  on  NOLs  used  by Ambac Assurance  in 
2017.  In  May  2018,  Ambac  executed  a  waiver  under  the 
intercompany  tax  sharing  agreement  pursuant  to  which Ambac 
Assurance was relieved of the requirement to make this payment  
by  June  1,  2018.  Ambac  has  also  agreed  to  defer  the  tolling 
payment for the use of net operating losses by Ambac Assurance 
in 2017 until such time as OCI consents to the payment. Ambac 
has accrued $14 million of additional tolling payments in 2018, 
subject  to OCI's review of Ambac's 2018 tax positions. 

| Ambac Financial Group, Inc.   53   2018 FORM 10-K |

Under  an  inter-company  cost  allocation  agreement,  Ambac  is 
reimbursed by Ambac Assurance for a portion of certain operating 
costs  and  expenses  and,  if  approved  by  OCI,  entitled  to  an 
additional payment of up to $4 million per year to cover expenses 
not otherwise reimbursed. 

It is highly unlikely that Ambac Assurance will be able to make 
dividend  payments  to  Ambac  for  the  foreseeable  future  and 
therefore cash and investments, payments under the intercompany 
cost allocation agreement and future tolling payments, if any,  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”  in  this Annual 

Report  on  Form  10-K,  and  Note  8.  Insurance  Regulatory 
Restrictions to the Consolidated Financial Statements included in 
Part  II,  Item 8,  in  this Annual  Report  on  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  opportunities  to  grow  and  diversify 
Ambac, and the making of investments, including securities issued 
or  insured  by Ambac Assurance.    Future  uses  of  liquidity  may 
include  the  acquisition  or  capitalization  of  new  businesses.  
Contingencies could cause material liquidity strains. 

The following table includes aggregated information about contractual obligations for Ambac and its subsidiaries at December 31, 2018, 
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 Assurance’s surplus notes, the Ambac Note and Tier 2 Notes 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.

(1)  Amounts on surplus notes (excluding junior surplus notes) include principal on their scheduled maturity date and interest on scheduled payment date, 
including payment of previously deferred interest totaling $239 million on the next scheduled payment date of June 7, 2019.  Also includes all principal 
and interest on junior surplus notes on the date all future and existing senior indebtedness of Ambac Assurance, policy and other priority claims against 
Ambac Assurance have been paid in full (included in the more than 5 years column).  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. Except for a one-time payment of approximately six months of interest on the surplus notes (other than junior surplus notes) outstanding 
immediately after the Rehabilitation Exit Transactions, annually from 2011 through 2018, OCI disapproved scheduled interest payments. 

(2) 

(3) 

Includes principal on Ambac note as of December 31, 2018 to be paid on its legal maturity date of February 12, 2023, and scheduled interest payments. 
Interest amounts on this variable rate debt are projected at a rate of 7.80% which is based on the index rate in effect at the balance sheet date. These notes 
are subject to mandatory redemption provisions that could significantly accelerate the timing of required payments, as described further in Note 13. Long-
Term Debt to the Consolidated Financial Statements included in Part II, Item 8 in this Form 10-K.

Includes principal and compounded paid-in-kind interest on Tier 2 notes to be paid on their legal maturity date of February 12, 2055. These notes are 
subject to mandatory redemption provisions that could significantly accelerate the timing of required payments, as described further in Note 13. Long-
Term Debt to the Consolidated Financial Statements included in Part II, Item 8 in this Form 10-K.

(4)  Amount represents future lease payments on lease agreements existing as of December 31, 2018. In January 2019 Ambac entered into a sub-lease agreement 
for office space at One World Trade Center, New York, NY set to expire in January 2030 which includes future lease payments of approximately $27 
million. 

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

agreements and other outside services. 

(6)  Amount represents future payments relating to Ambac Assurance's postretirement medical reimbursements to current retirees over the next 10 years. 

(7)  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.

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,  including  from 
litigation 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 and loss adjustment expenses, claims, commutation 
and  related  expense  payments  on  insurance  policies,  ceded 
reinsurance  premiums,  principal  and  interest  payments  on  the 
Ambac Note, surplus note principal and interest payments, Tier 2 
Note payments, additional loans to affiliates and tolling payments 
due  to Ambac  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.  Any such payment on surplus notes 
would require either payment or collateralization of a portion of 
the Tier 2 Notes under the terms of the Tier 2 Note indenture.  See 
Note  13.  Long-term  Debt  to  the  Consolidated  Financial 
Statements, included in Part II, Item 8 in this Form 10-K for further 
discussion of the payment terms and conditions of the Tier 2 Notes.  

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

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. Refer to Note 1. Background and Business Description 
for a discussion of the August 2018 AMPS Exchange that reduced 
the  liquidation  preference  of  the AMPS  from  $660.3  million  at 
June  30,  2018  to  $102.9  million as  of August  1,  2018.   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”  in  this Annual 
Report  on  Form  10-K,  and  Note  8.  Insurance  Regulatory 
Restrictions to the Consolidated Financial Statements included in 
Part  II,  Item 8,  in  this Annual  Report  on  Form  10-K,  for  more 
information on dividend payment restrictions. 

Our  ability  to  realize  RMBS  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 OCI, which could impede our 
ability  to  take  actions  required  to  realize  such  recoveries,  and 
uncertainty  inherent  in  the  assumptions  used  in  estimating  the 
amount  of  such  recoveries.  The  amount  of  these  subrogation 

recoveries  is  significant  and  if  we  are  unable  to  recover  any 
amounts or recover materially less than our estimated recoveries, 
our  future  available  liquidity  to  pay  claims  and  meet  our  other 
obligations would be reduced materially.  See Part I, Item 1A. Risk 
Factors in this Annual Report on Form 10-K for more information 
about risks relating to our RMBS R&W subrogation recoveries.

Ambac Financial Services ("AFS") Liquidity.  AFS uses interest 
rate derivatives as an economic hedge against the effects of rising 
interest  rates  elsewhere  in  the  Company,  including  on Ambac’s 
financial guarantee exposures.  These derivatives include, interest 
rate swaps previously provided to states, municipalities and their 
authorities, asset-backed issuers and other entities in connection 
with their financings.   The principal uses of liquidity by AFS are 
payments  on  intercompany  loans,  payments  under  derivative 
contracts (primarily interest rate swaps and US Treasury futures), 
collateral posting and operating expenses. AFS borrows cash and 
securities from Ambac Assurance to meet liquidity needs under an
established lending agreement with defined borrowing limits that 
has received non-disapproval from OCI.

Operating activities

The following represents the significant cash activities during the 
years ended December 31, 2018, 2017 and 2016 :

•  Cash  outflow  from  the  Rehabilitation  Exit Transactions  to 
third parties was $1,354 million of which $1,162 million is 
included  in  operating  activities  and  $191  is  included  in 
financing activities as it related to payments for surplus note 
principal. See Note 1. Background and Business Description 
to the Consolidated Financial Statements, included in Part II, 
Item  8  in  this  Form  10-K  for  details  regarding  the 
Rehabilitation Exit Transactions;

•  During  the  year  ended  December  31,  2018, Ambac  made 
payment  of  interest  on  long-term  debt  of  $143  million, 
including $11 million on surplus notes made in connection 
with the Rehabilitation Exit Transactions, $130 million on the 
Ambac Note and $2 million on the secured borrowing which 
was fully repaid in June 2018;

•  During  the  year  ended  December  31,  2017, Ambac  made 
payments of $94 million to commute interest rate swaps with 
a special purpose entity;

•  During  the  year  ended  December 31,  2017, Ambac  made 
payments of $105 million to extinguish (on a consolidated 
basis)  principal  and  interest  of  surplus  notes  and  settled 
certain  residual  obligations  related  to  previously  called 
surplus notes ($69 million principal and $35 million interest).

The  interest  amount  reduces  operating  cash  flows  and  the 
principal reduced financing cash flows; and 

•  Net  loss  and  loss  expenses  paid,  including  commutation 
payments, during  the years ended December 31, 2018, 2017 
and 2016 are detailed below:

•  During the year ended December 31, 2018, 2017 and 2016 
tax payments amounted to $35 million, $40 million and $21 
million respectively.

Future operating cash flows will primarily be impacted by the level 
of premium collections, investment coupon receipts and claim or 
commutation payments. 

Financing Activities

Financing  activities  for  the  year  ended  December  31,  2018 
included  proceeds  from  the  issuance  of  Tier  2  Notes  of  $240 
million,  paydowns of Ambac Note of $214 million, repayments 
of  the  Secured  Borrowing  of  $74  million,  payments  for  the 
extinguishment of surplus notes of $191 million (in connection 
with the Rehabilitation Exit Transactions) and paydowns of VIE 
debt obligations of $349 million.

Financing  activities  for  the  year  ended  December  31,  2017 
included  paydowns  on  a  secured  borrowing  of  $29  million, 
payments for investment agreements of $82 million, payments for 
extinguishment of surplus notes of $69 million and paydowns of 
VIE debt obligations of $230 million.

Financing  Activities  for  the  year  ended  December  31,  2016 
included  repayments  of  secured  borrowing  of  $29  million, 
payments for investment agreements of $18 million, payments for 
the extinguishment of surplus notes of $20 million, acquisition of 
Ambac  warrants  of  $3  million,  and  paydowns  of  VIE  debt 
obligations of $249 million.

Principal and interest due on the debt issued in connection with 
the Rehabilitation Exit Transactions as well as future payments on 
the remaining surplus notes will impact Ambac's future cash flows.

Collateral

AFS  hedges  a  portion  of  the  interest  rate  risk  in  the  financial 
guarantee and investment portfolio, along with legacy customer 
interest  rate  swaps,  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 or U.S. Treasury obligations 
with market values equal to or in excess of market values of the 
swaps and futures contracts. AFS may look to re-establish hedge 
positions that are terminated early, resulting 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 $103 million (cash and securities classified as cash 
equivalents), 
these 
contracts at December 31, 2018. 

independent  amounts,  under 

including 

Ambac Credit Products (“ACP”) is not required to post collateral 
under any of its outstanding derivative contracts.

BALANCE SHEET

Total  assets  decreased  by  approximately  $8,604  million  from 
December 31,  2017  to  $14,589  million  at  December 31,  2018, 
primarily due to (i) the deconsolidation of four VIEs during 2018 
(causing a reduction in assets of $6,620 million) and (ii) the net 
impact of the Rehabilitation Exit Transactions as discussed below.   
Other significant changes during 2018 were lower VIE assets as a 
result of currency changes (weakening of the British Pound), lower 
intangible assets as a result of amortization, and lower invested 
assets due to claim payments and debt redemptions. 

Total liabilities decreased by approximately $8,592 million from 
December 31, 2017 to $12,956 million as of December 31, 2018, 
primarily as a result of (i) the deconsolidation of four VIEs during 
2018 (causing a reduction in liabilities of $6,600 million), (ii) the 
Rehabilitation Exit Transactions as discussed below and (iii) the 
AMPS Exchange transaction which increased the carrying value 
of surplus notes and the related accrued interest by an aggregate 
of $286 million, respectively.  Other significant changes during 
2018 were lower VIE liabilities as a result of currency changes, 
lower unearned premiums from the runoff of the insured portfolio, 
lower loss reserves due to claim payments, the full redemption of 
the Secured Borrowing transaction on June 22, 2018 and partial 
paydowns on the Ambac Note, partially offset by higher accrued 
interest payable on surplus notes and new debt.

As of December 31, 2018 total stockholders’ equity was $1,633 
million, compared with total stockholders’ equity of $1,645 million
at December 31, 2017. This decrease was primarily driven by the 
AMPS  Exchange  transaction  which  reduced  total  stockholders' 
equity by $297 million and translation losses related to Ambac's 
foreign subsidiaries, partially offset by net income and unrealized 
gains on investment securities. 

Rehabilitation Exit Transactions. As more fully discussed in Note 
1.  Background  and  Business  Description  to  the  Consolidated 
Financial Statements, included in Part II, Item 8 in this Form 10-
K  on  February  12,  2018,  the  Second  Amended  Plan  of 
Rehabilitation  became  effective  and  the  Rehabilitation  Exit 
Transactions  were  consummated.  The  Rehabilitation  Exit 
Transactions  had  a  significant  impact  on  the  comparability  of 

| Ambac Financial Group, Inc.   56   2018 FORM 10-K |

Ambac's  financial  results  between  2018  and  prior  years.  The 
Rehabilitation Exit Transactions impacted the following balance 
sheet accounts:

• Invested assets and cash were reduced by a total of $1,801
million driven by (i) a cash outflow of  $1,354 million and
(ii) the settlement of Ambac-insured RMBS securities held
in the investment portfolio of $1,455 million, partially offset
by the receipt of $768 million par amount of the Secured Notes
and proceeds from the issuance of Tier 2 notes of $240 million.

• Loss Reserves and Subrogation Recoverable were reduced
and increased, respectively, as a result of the settlement of
unpaid  claims  of  the  Segregated  Account,  which  were
approximately  $3,867  million,  including  $840  million  of
accrued  interest  at  December  31,  2017  ($3,857  million  at
February 12, 2018).  Loss Reserves included $3,080 million
of unpaid claims and accrued interest at December 31, 2017.
Subrogation Recoverable was net of $787 million of unpaid
claims and accrued interest at December 31, 2017.  Following
the settlement of Deferred Amounts, Loss Reserves decreased
$2,555  million  and  Subrogation  Recoverable  increased
$1,312 million.   As a result of the settlement of unpaid claims,
certain policies which were previously in a liability position
have transitioned to an asset position with a recoverable of
$525 million at December 31, 2017.

• Long-term debt was increased by $1,748 million driven by
(i) the Ambac  Note  issued  to Ambac  LSNI  with  an  initial
carrying value of approximately $2,146 million and (ii) the
issuance  of Tier  2  Notes  with  an    initial  carrying  value  of
the
approximately  $231  million,  partially  offset  by 
consolidated reduction of surplus notes principal and interest
with a carrying value of approximately $629 million.  Refer
to  Note  13.  Long-term  Debt  to  the  Consolidated  Financial
Statements, included in Part II, Item 8 in this Form 10-K for
further information regarding Ambac's debt obligations.

Investment Portfolio. Ambac Assurance’s investment objective is 
to achieve the highest risk-adjusted after-tax return on a diversified 
portfolio of primarily fixed income investments while employing 
asset/liability  management  practices  to  satisfy  operating  and 
strategic liquidity needs. Ambac Assurance’s investment portfolio 
is subject to internal investment guidelines and is subject to limits 
on types and quality of investments imposed by the insurance laws 
and regulations of the jurisdictions in which it is licensed, primarily 
the States of Wisconsin and New York. Such guidelines set forth 
minimum credit rating requirements and credit risk concentration 
limits. Within these guidelines, which in certain instances may be

Includes investments guaranteed by Ambac Assurance and Ambac 
UK for both years presented.  Refer to Note 10. Investments in this 
10-K located in Part II. Item 8 for further details 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 is CC and CCC- as of December 31, 2018, and C 
and CCC as of December 31, 2017, respectively.

The following tables provide the ratings(1) distribution of the fixed 
income investment portfolio based on fair value at December 31, 
2018 and 2017.

(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 57% and 64% of the 2018 and 2017 combined portfolio, 
respectively. The decrease in the percentage of not rated and below 
investment  grade  holdings  since  December 31,  2017  is  driven  by 
the 
reductions 

in  Ambac-insured  RMBS 

resulting 

from 

Rehabilitation Exit Transactions and subsequent sales, partially offset 
by the receipt of Secured Notes issued by Ambac LSNI.

Premium Receivables. Ambac either received premium upfront at 
time of issuance of the insurance policy or in installments over the 
policy  term.    For  installment  premium  transactions,  a  premium 
receivable asset is established equal to the (i) present value of future 
contractual  premiums  due  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.   Ambac's  premium  receivables 
decreased to $495 million at December 31, 2018 from $586 million
at  December 31, 2017.  As further discussed in Note 7. Financial 
Guarantee Insurance Contracts, the decrease is due to premium 
receipts, adjustments for changes in expected and contractual cash 
flows  and  the  impact  of  currency  exchange  rates  on  non-US 
denominated  future  premiums,  partially  offset  by  accretion  of 
premium receivable discount.

Reinsurance Recoverable on Paid and Unpaid Losses.  Ambac 
Assurance has reinsurance in place pursuant to surplus share treaty 
and  facultative  agreements. 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 under 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 
reinsurer  (among  other  events  and  circumstances).  Ambac 
Assurance benefited from letters of credit and collateral amounting 
to approximately $114 million from its reinsurers at December 31, 
2018.  Collateral is based on reinsurance contracts, but generally 
includes  reinsurers  share  of  loss  and  loss  expense  reserves  and 
statutory unearned premiums and contingency reserves, amongst 
other  considerations.    As  of  December  31,  2018  and  2017, 
reinsurance  recoverable  on  paid  and  unpaid  losses  were  $23 
million and $41 million, respectively.  The decrease was primarily 
a result of the commutation of student loan exposures.

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. The net intangible asset at December 31, 2018 and 2017 
was $719 million and $847 million, respectively.  The decrease 
was primarily driven by amortization expense of $107 million and 
translation  losses  from  the  consolidation  of  Ambac's  foreign 
subsidiary (Ambac UK). 

Loss and Loss Expense Reserves and Subrogation Recoverable.
Loss and loss expense reserves are based upon estimates of the 
ultimate aggregate losses inherent in the non-derivative portfolio

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”), student loan securities and public finance bond types. 
These  bond  types  represent  93%  of  our  ever-to-date  insurance 
claims recorded with RMBS comprising 79%.

(3)  Loss reserves are included in the balance sheet as Loss and loss expense reserves or Subrogation recoverable dependent on if a policy is in a net liability 

or net recoverable position.

RMBS

Ambac  has  exposure  to  the  U.S.  mortgage  market  primarily 
including 
through  direct  financial  guarantees  of  RMBS, 
transactions collateralized by first and second liens. The decrease 
in RMBS gross loss reserves was primarily related to the settlement 
of Deferred Amounts and interest accrued on Deferred Amounts 
in connection with the Rehabilitation Exit Transactions executed 
on February 12, 2018.

We established an RMBS R&W 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 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 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 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. See Part I, Item 1A. Risk Factors in 
this Annual Report on Form 10-K for more information about risks 
relating to our RMBS R&W subrogation recoveries.

Public Finance

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 decrease in public finance gross loss 
reserves at December 31, 2018 as compared to December 31, 2017
was primarily related to the payment of claims, primarily Puerto 
Rico.  Total public finance gross loss reserves and related gross

Long-term Debt:

Long-term debt consists of senior and junior surplus notes issued 
by Ambac Assurance, the Ambac Note and Tier 2 Notes issued in 
connection  with  the  Rehabilitation  Exit  Transactions  and  the

The  increase  in  long-term  debt  from  December 31,  2017  is 
primarily due to the impact of the Rehabilitation Exit Transactions 
that resulted in the issuance of the Ambac Note and Tier 2 Note 
and the redemption of a portion of the senior surplus notes then 
outstanding. Through   December 31, 2018 the Ambac Note was 
partially reduced by redemptions of $214 million and the Tier 2 
notes balance increased  due to paid-in-kind interest and discount 
accretion.  Surplus notes outstanding increased subsequent to the 
Rehabilitation  Exit  Transactions  due  to  issuances  by  Ambac 
Assurance  in  connection  with  the  third  quarter  2018  AMPS 
Exchange and Ambac's resales of notes to the market.   The Secured 
Borrowing was fully repaid in 2018.

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 and Everspan'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 and  Everspan 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, 2018 and 2017 
was  less  than  NAIC  SAP  by  $42  million  and  $104  million, 
respectively. 

Ambac Assurance’s statutory policyholder surplus and qualified 
statutory capital (defined as the sum of policyholders surplus and 
mandatory contingency reserves) were $1,152 million and $1,648 
million at December 31, 2018, respectively, as compared to $700 
million and $1,156 million at December 31, 2017, respectively. 
The drivers to the net increase were Ambac Assurance’s statutory 
net income and reclassifications of $361 million of surplus notes 
from liabilities to a component of policyholders surplus partially 
offset by a decline in fair value of below investment grade bond 
investments  of  $72  million  and  contributions  to  contingency 
reserves. 

Ambac Assurance’s statutory policyholder surplus includes $367 
million of junior surplus notes. These junior surplus notes, as well 
as preferred stock issued by Ambac Assurance with a liquidation 
preference of $137.5 million, are obligations that have claims on 
the resources of Ambac Assurance which impact Ambac's ability 
to realize residual value from its equity in Ambac Assurance.

As further discussed in Financial Guarantees in Force above in the 
Management Discussion and Analysis section of this Form 10-K, 
pursuant to the COFINA Plan of Adjustment that was effective on 
February  12.  2019,  each  holder  of  Ambac  Assurance-insured 
senior COFINA bonds had the option to elect to either (i) commute 

their rights in respect of the Ambac Assurance insurance policy 
associated with the existing senior COFINA bonds, which bonds 
would be discharged and Ambac policy obligations with respect 
thereto would be released, in exchange for new COFINA bonds, 
cash  amounts  to  be  paid  by  COFINA,  plus  additional  cash 
consideration provided by Ambac Assurance equal to 5.25% of the 
accreted value of the Ambac Assurance-insured senior COFINA 
bonds as of the COFINA petition date or (ii) exchange their senior 
COFINA bonds for units issued by a trust (the "COFINA Class 2 
Trust"), which trust would receive the new COFINA bonds and 
the cash amounts to be paid by COFINA that such holders would 
have otherwise received to the extent they had elected the recovery 
under clause (i) above (thereby entitling the trust to receive debt 
service payments from COFINA with respect to the new COFINA 
bonds deposited into the trust).  

•  The  commutation  transactions  resulted  in  a  reduction  of 
Ambac  Assurance's  insured  exposure  to  COFINA  by 
approximately 75% and an incurred loss of $37.3 million in 
2019, which will be offset by accelerated earned premiums 
of $29.6 million on the insured exposures being commuted.  

•  The  non-commuted  portion  of  Ambac  Assurance's  policy 
(approximately 25%) or net par exposure of $202 million will 
remain  in  force.  This  remaining  policy  portion  of Ambac 
Assurance's COFINA exposure together with old COFINA 
bonds have been deposited into a trust together with the new 
COFINA  bonds  and  cash  and  the  non-commuted Ambac-
insured  bondholders  receiving  units  of  the  trust  in  return.  
Cash flows from the new COFINA bonds and cash will be 
passed  through  to  unit-holders  over  time  and  will  reduce 
amounts owed under the remaining Ambac Assurance policy. 

Ambac  Assurance’s  statutory  surplus  is  sensitive  to  multiple 
factors, including: (i) loss reserve development, (ii) approval by 
OCI of principal or interest payments on existing surplus notes, 
(iii) approval by OCI of principal or interest payments on existing 
junior surplus notes, (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 or resolutions 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  investment  securities,  and 
(xi) future changes to prescribed SAP practices by the OCI. 

As of December 31, 2018, total unpaid interest, which will require 
OCI approval for payment, for surplus notes outstanding to third 
parties and junior surplus notes was $239 million and $108 million, 
respectively, at the scheduled interest payment date of June 7, 2018.  
Under  SAP,  these  amounts  will  be  recorded  as  a  liability  once 
approval for payment has been granted by OCI.   

| Ambac Financial Group, Inc.   61   2018 FORM 10-K |

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

•  Loss reserves are only established for losses on guaranteed 
obligations  that  have  experienced  a  payment  default  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 
binding commutation contract is signed by the counterparty.  
Under GAAP, in addition to the 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 2.8%. 

•  Mandatory contingency reserves are required based upon the 
type of obligation insured, whereas GAAP does not require

•  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. 

•  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 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 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. 

•  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 
required 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  £262.7  million  at  December 31,  2018  as 
compared to £266.3 million at December 31, 2017. The reduction 
in  Ambac  UK’s  shareholders’  funds  was  primarily  due  to  the 
increase in loss provisions over the year driven by a lower discount 
rate, offset by net income arising from the receipt of premiums and 
investment  return  in  the  period.    At  December 31,  2018,  the 
carrying  value  of  cash  and  investments  was  £498  million,  an 
increase from £460 million at December 31, 2017. The increase in 
cash and investments is due to the continued receipt of premiums, 
investment  returns  from  Ambac  UK's  investment  portfolio, 
unrealized foreign exchange gains on investments denominated in 
currencies  other  then Ambac  UK's  functional  currency  (British 
Pounds) in the period, offset by loss expenses, tax and overhead 
payments.

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  2.46%)  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 2.8% 
for Ambac UK related transactions. 

•  Investments in fixed income securities are stated at amortized 
cost,  subject 
impairment 
to  an  other-than-temporary 
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.  

| Ambac Financial Group, Inc.   62   2018 FORM 10-K |

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. 

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.  The calculation of capital resources, 
regulatory  capital  requirements  and  regulatory  capital  deficits 
under Solvency II at December 31, 2018 will be be published on 
Ambac's website during March. Final annual Solvency II data and 
Ambac UK's annual Solvency and Financial Condition Report will 
be published on Ambac's website on April 22, 2019.

Available capital resources under Solvency II were a surplus of 
£110.2  million  at  December 31,  2018  (based  on  the  quarterly 
Solvency II filing made on February 11, 2019 which may be subject 
to update in the final annual Solvency II filing noted above) an 
improvement from a surplus of £55.1 million at January 1, 2018.  
Of  these  available  capital    resources  the  value  eligible  to  meet 
solvency capital requirements at December 31, 2018 was £110.2 
million  in  comparison  to  £17.0  million  as  at  January 1,  2018.  
Eligible  capital  resources  at  December 31,  2018  and  January 1, 
2018  are  in  comparison  to  regulatory  capital  requirements  of 
£357.4  million  and  £346.3  million,  respectively. Ambac  UK  is 
therefore  deficient  in  terms  of  compliance  with  applicable 
regulatory  capital  requirements  by  £247.2  million  and  £329.3 
million at December 31, 2018 and January 1, 2018, respectively.  
The regulators are aware of the deficiency in capital resources as 
compared to capital requirements and dialogue between Ambac 
UK management and its regulators remains ongoing with respect 
to options for addressing the shortcoming, although such options 
remain few.

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. 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, 
we utilized a 0% effective tax rate for non-GAAP adjustments; 
which is subject to change.  

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 (Loss).  Adjusted Earnings (Loss) is defined 
as  net  income  (loss)  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 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  contracts  to  be  accounted  for 
consistent with the Financial Services – Insurance Topic of 
ASC, whether or not they are subject to derivative accounting 
rules. 

•  Insurance  intangible  amortization:  Elimination  of  the 
amortization of the financial guarantee insurance intangible 
asset that arose as a result of the implementation of Fresh Start 
reporting.  These  adjustments  ensure  that  all  financial 
guarantee  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.  This 
adjustment eliminates the foreign exchange gains (losses) on 
all  assets,  liabilities  and  transactions  in  non-functional 
currencies, which 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. 

| Ambac Financial Group, Inc.   63   2018 FORM 10-K |

•  Fair value (gain) loss on interest rate derivative from Ambac 
CVA: Elimination of the gains (losses) relating to Ambac’s 
CVA on interest rate derivative contracts.  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.

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. Included 
within Net income (loss) attributable to common stockholders of 
these consolidated VIEs was $3 million, $20 million, and $(14) 
million for the years ended December 31, 2018, 2017 and 2016, 
respectively. Had these financial guarantee VIEs been accounted 
for under the provisions of the Financial Services - Insurance Topic 
of the ASC, the impact would have been $20 million, $50 million 
and $148 million for the years ended December 31, 2018, 2017 
and  2016,  respectively.  The  net  impact  of  these  different 
accounting  bases  on  Net  income  attributable  to  common 
stockholders (including per share amounts) was $16 million ($0.35 
per share), $31 million ($0.68 per diluted share) and $162 million 
($3.54 per diluted share), for the years ended December 31, 2018, 
2017 and 2016, 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 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  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 of 

emergence 

bankruptcy 

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

and 

•  Ambac CVA on interest rate derivative liabilities: Elimination 
of the gain relating to Ambac’s CVA on interest rate derivative 
contracts. 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.

comprehensive income (“AOCI”). The AOCI component of 
the  fair  value  adjustment  on  the  investment  portfolio  may

Interest Rate Risk:

Financial  instruments  for  which  fair  value  may  be  affected  by 
changes  in  interest  rates  consist  primarily  of  fixed  income 
investment securities, long-term debt and interest rate derivatives. 
Fixed income investment securities that are guaranteed by Ambac 
have interest rate risk 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.

Changes in fair value resulting from changes in interest rates are 
driven  primarily  by  the  impact  of  interest  rate  shifts  on  the 
investment portfolio (which produce net fair value losses as rates 
increase)  and  long-term  debt  and  the  interest  rate  derivatives 
portfolio (which produce net fair value gains as rates increase). 
Interest rate increases would also have a negative economic impact 
on expected future claim payments within the financial guarantee 
portfolio,  most  notably  for  RMBS  and  student  loan  policies. 
Ambac  performs  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.

The interest rate derivatives portfolio is managed 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 derivatives portfolio attributable to the macro-hedge position 
would produce mark-to-market gains or losses of approximately 
$0.9 million for a 1 basis point parallel shift in USD benchmark 
interest rates up or down at December 31, 2018.

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. 
stockholders' equity of these consolidated VIEs was $112 million 
and $134 million at December 31, 2018 and 2017, 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 $148 
million  and  $179  million  at  December  31,  2018  and  2017, 
respectively. The net change of these different accounting bases 
(including per share amounts) was $36 million ($0.79 per share) 
and $45 million ($0.99 per share), at December 31, 2018 and 2017, 
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,  2017  to  December 31,  2018  was 
primarily driven by Adjusted earnings.

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 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. 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. 

| Ambac Financial Group, Inc.   65   2018 FORM 10-K |

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, 2018:

spreads as much as 250 basis points would result in less than a $1 
million  impact  to  the  fair  value  of  derivatives  at  December 31, 
2018.    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.

Due to the low interest rate environment as of December 31, 2018, 
stress scenarios involving interest rate declines greater than 200 
basis points are not meaningful to Ambac's portfolios.

Credit Spread Risk:

Financial instruments that may be adversely affected by changes 
in spreads include Ambac’s outstanding credit derivative contracts, 
certain interest rate derivatives 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 derivatives at December 31, 2018.  It 
is more likely that actual changes in credit spreads will vary by 
obligor:

related 

Ambac’s  fixed  income  investment  portfolio  contains  securities 
with  different  sensitivities  to  and  volatility  of  spreads.  Fixed 
income  securities  that  are  guaranteed  by  Ambac  and  were 
purchased in Ambac's investment portfolio have credit spread risk 
characteristics that behave inversely to those associated with future 
financial guarantee claim payments.  Accordingly such securities 
are excluded from the company's spread sensitivity measures.  The 
following table summarizes the estimated change in fair values of 
Ambac’s fixed income investment portfolio assuming immediate 
shifts  in  credit  spreads  across  all  holdings  other  than  Ambac 
guaranteed securities at December 31, 2018.  It is more likely that 
actual changes in credit spreads will vary by security:

Ambac has financial instruments denominated in currencies other 
than the U.S. dollar, primarily pounds sterling and euros. These 
financial instruments are primarily invested assets of Ambac UK.

Also  included  in  the  fair  value  of  derivatives  is  the  effect  of 
Ambac’s  creditworthiness,  which  reflects  market  perception  of 
Ambac’s ability to meet its obligations.  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.  As  a  result  of  runoff  of 
uncollateralized  interest  rate  and  credit  default  swap  liabilities,  
Ambac’s credit valuation adjustment included in the determination 
of fair value has resulted in  $0.1 million reduction to derivative 
liabilities as of December 31, 2018.  An increase in Ambac credit

Report of Independent Registered Public Accounting Firm

Definition and Limitations of Internal Control Over Financial 
Reporting 

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.

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

Opinion on Internal Control Over Financial Reporting

Inc.  and 
We  have  audited  Ambac  Financial  Group, 
subsidiaries'  (the  Company)  internal  control  over  financial 
reporting as of December 31, 2018, based on criteria established 
in Internal Control - Integrated Framework (2013) issued by the 
Committee  of  Sponsoring  Organizations  of  the  Treadway 
Commission.  In  our  opinion,  the  Company  maintained,  in  all 
material respects, effective internal control over financial reporting 
as of December 31, 2018, based on criteria established in Internal 
Control - Integrated Framework (2013) issued by the Committee 
of Sponsoring Organizations of the Treadway Commission.

We  also  have  audited,  in  accordance  with  the  standards  of  the 
Public  Company  Accounting  Oversight  Board  (United  States) 
(PCAOB), the consolidated balance sheets of the Company as of 
December 31, 2018 and 2017, the related consolidated statements 
of  total  comprehensive  income  (loss),  stockholders’  equity,  and 
cash flows for each  of the years in the three-year period ended 
December 31, 2018, and the related notes and financial statement 
schedules (collectively, the consolidated financial statements), and 
our  report  dated  February 28,  2019  expressed  an  unqualified 
opinion on those consolidated financial statements.

Basis for Opinion 

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 are a public accounting 
firm registered with the PCAOB and are required to be independent 
with respect to the Company in accordance with the U.S. federal 
securities  laws  and  the  applicable  rules  and  regulations  of  the 
Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the 
PCAOB. 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  of  internal  control  over  financial 
reporting 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.

Opinion on the Consolidated Financial Statements

Basis for Opinion

We have audited the accompanying consolidated balance sheets of 
Ambac Financial Group, Inc. and subsidiaries (the Company) as 
of  December  31,  2018  and  2017,  the  related  consolidated 
statements  of  total  comprehensive  income  (loss),  stockholders’

ended  December 31,  2018,  and  the  related  notes  and  financial 
statement  schedules  (collectively,  the  consolidated  financial 
statements). In our opinion, the consolidated financial statements 
present fairly, in all material respects, the financial position of the 
Company as of December 31, 2018 and 2017, and the results of 
its operations and its cash flows for each of the years in the three-
year  period  ended  December 31,  2018,  in  conformity  with 
U.S. generally accepted accounting principles.

We  also  have  audited,  in  accordance  with  the  standards  of  the 
Public  Company  Accounting  Oversight  Board  (United  States)

opinion on the effectiveness of the Company’s internal control over 
financial reporting.

These consolidated financial statements are the responsibility of 
the Company’s management. Our responsibility is to express an 
opinion on these consolidated financial statements based on our 
audits. We are a public accounting firm registered with the PCAOB 
and are required to be independent with respect to the Company

applicable rules and regulations of the Securities and Exchange 
Commission and the PCAOB.

We conducted our audits in accordance with the standards of the 
PCAOB. Those standards require that we plan and perform the 
audit 
the 
to  obtain  reasonable  assurance  about  whether 
consolidated 
free  of  material 
misstatement, whether due to error or fraud. Our audits included 
performing procedures to assess the risks of material misstatement 
of the consolidated financial statements, whether due to error or 
fraud, and performing procedures that respond to those risks. Such 
procedures included examining, on a test basis, evidence regarding 
the  amounts  and  disclosures  in  the  consolidated  financial 
statements.  Our  audits  also  included  evaluating  the  accounting 
principles used and significant estimates made by management, as 
well  as  evaluating  the  overall  presentation  of  the  consolidated 
financial  statements.  We  believe  that  our  audits  provide  a 
reasonable basis for our opinion.

1. 

BACKGROUND AND BUSINESS DESCRIPTION

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.

Ambac provides financial guarantee insurance policies through its 
principal  operating  subsidiary,  Ambac  Assurance  Corporation 
(“Ambac Assurance" or "AAC") and its wholly owned subsidiary, 
Ambac Assurance UK Limited (“Ambac UK”). 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 
subsidiary, Everspan Financial Guarantee Corp., 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 and Ambac 
UK from being able to write new business. The 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 and by the terms of the Settlement Agreement, 
dated  as  of  June 7,  2010,  as  amended  (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 Stipulation and 
Order among the Office of the Commissioner of Insurance for the 
State  of Wisconsin  (“OCI”), Ambac  and Ambac Assurance  that 
became  effective  on  February  12,  2018,  as  amended  (the 
“Stipulation and Order”), the terms of the indenture for the Tier 2 
Notes (as defined below), which are substantially similar to the 
terms of the Settlement Agreement in this regard, and the terms of 
its  Auction  Market  Preferred  Shares  ("AMPS").  It  is  highly 
unlikely  that Ambac Assurance  will  be  able  to  make  dividend 
payments to Ambac for the foreseeable future.

Management  reviews  financial  information,  allocates  resources 
and measures financial performance on a consolidated basis. As a 
result, the Company has a single reportable segment.

Limitations on Voting and Transfer of Common Stock

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 the OCI.  Article 
XII  contains  substantial  restrictions  on  the  ability  to  transfer 
Ambac’s common stock.  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. 

On  October  11,  2018, Ambac  received  a  Private  Letter  Ruling 
(“PLR”)  from  the  U.S.  Internal  Revenue  Service  (“IRS”)  with 
regard to certain aspects of Section 382 of the Internal Revenue 
Code of 1986, as amended. Section 382 generally limits the use of 
a  corporation’s  net  operating  loss  carryforwards  when  an 
ownership change occurs.  An ownership change results if there is 
a cumulative increase of more than 50 percentage points in the 
amount of stock held by one or more “5% shareholders” of the 
corporation during a three-year testing period. A group of persons 
who  have  a  formal  or  informal  understanding  to  make  a 
coordinated acquisition of stock is treated as a single entity for 
these purposes.

The PLR addresses the ownership of Ambac’s common stock by 
three  separate  groups  of  funds  and  accounts  managed  by  three 
separate investment advisors. In the PLR the IRS ruled that, based 
on certain facts and representations, for purposes of Section 382 
each investment advisor will not be treated as the owner of the 
shares which it holds on behalf of the funds and accounts it advises, 
and each group of funds and accounts will not be treated as a single 
entity.  The conclusions in the PLR are based on the particular facts 
and  circumstances  set  forth  in  Ambac’s  request  for  the  PLR, 

| Ambac Financial Group, Inc.   74   2018 FORM 10-K |

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

including those set forth in representations provided in writing by 
the investment advisors to Ambac, such as the current and expected 
future investment strategies of the funds and accounts managed by 
these  investment  advisors,  the  current  and  expected  manner  in 
which  the  funds  and  accounts,  and  the  investment  decisions 
regarding Ambac’s common stock, are managed by these investor 
advisors,  and  the  current  and  expected  tax  classification  of  the 
funds managed by these investment advisors.  The PLR does not 
address the application of Section 382 to any Ambac shareholder 
other than those specifically addressed in the PLR. Ambac reserves 
all rights under its Charter regarding transfers and voting of its 
stock and other securities, including those unrelated to Section 382. 
Furthermore,  receipt  of  the  PLR  does  not  affect  any  voting  or 
ownership  restrictions  that  may  apply  to  holders  of  Ambac’s 
common stock pursuant to applicable law.

As a result of the PLR, neither the investment advisors specifically 
addressed therein nor the funds and accounts they advise will be 
treated by Ambac as 5% shareholders for purposes of Article XII 
of the Charter unless any representation provided to Ambac by an 
investment advisor ceases to be true, including that no individual 
fund or account owns 5% or more of Ambac’s common stock. 

Strategies to Enhance Shareholder Value

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, 
reinsurance, settlements and restructurings, with a focus on 
our  watch  list  credits  and  known  and  potential  future 
adversely classified credits, that we believe will improve our 
risk  profile,  and  maximizing  the  risk-adjusted  return  on 
invested assets;

•  Ongoing  rationalization  of  Ambac's  and  its  subsidiaries' 

capital and liability structures;

•  Loss  recovery  through  active  litigation  management  and 

exercise of contractual and legal rights;

•  Ongoing  review  of  the  effectiveness  and  efficiency  of 

Ambac's operating platform; and

•  Evaluation of opportunities in certain business sectors that 
meet  acceptable  criteria  that  will  generate  long-term 
stockholder value with attractive risk-adjusted returns.

With  respect  to  our  new  business  strategy,  we  have  identified 
certain business sectors adjacent to Ambac's core business in which 
future opportunities will be evaluated.  We have been evaluating 
strategic opportunities in credit, insurance, asset management and 
other financial services that we believe would be synergistic to 
Ambac  and  would  leverage  our  core  competencies. We  will  be 
measured  and  disciplined  in  our  approach  as  we  consider  and 
pursue opportunities to deploy our capital with the goal of creating 
sustainable  long-term  shareholder  value.    Although  we  are 
exploring new business opportunities for Ambac, no assurance can 
be  given  that  we  will  be  able  to  identify  or  execute  a  suitable 
transaction and/or obtain the financial and other resources that may 
be required to finance the acquisition or development of any new 
businesses or assets.  

The execution of Ambac’s objective to increase the value of its 
investment  in Ambac Assurance  is  subject  to  the  rights  of  OCI 
under the Stipulation and Order, which requires OCI to approve 
certain actions taken by or in respect of Ambac Assurance, as well 
as restrictions in the Settlement Agreement and in the indenture 
for the Tier 2 Notes.  Opportunities for remediating losses on poorly 
performing insured transactions also depend on market conditions, 
including 
its 
subsidiaries' creditworthiness, the structure of the underlying risk 
and associated policy as well as other counterparty specific factors.  
Decisions by OCI 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. 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 remains speculative.

the  perception  of  Ambac  Assurance’s  and 

The Segregated Account

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 Wisconsin Insurance Commissioner, acting as 
rehabilitator  (the  "Rehabilitator")  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 
the  Wisconsin  Insurers  Rehabilitation  and 
provisions  of 
Liquidation  Act.    On  October 8,  2010,  OCI  filed  a  plan  of 
rehabilitation  for  the  Segregated  Account  (the  “Segregated 
Account Rehabilitation Plan”) in the Rehabilitation Court, which 
was  confirmed  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.  Policy obligations not allocated to the Segregated Account 
remained in the General Account of Ambac Assurance, and such 
policies in the General Account were not subject to and, therefore, 
were  not  directly 
the  Segregated  Account 
Rehabilitation Plan.

impacted  by 

On February 12, 2018, the rehabilitation of the Segregated Account 
was  concluded  pursuant  to  an  amendment  to  the  Segregated 
Account  Rehabilitation  Plan  (the  "Second  Amended  Plan  of 
Rehabilitation").  The conclusion of the rehabilitation followed the 
successful  completion  of Ambac's  surplus  note  exchange  offers 
and consent solicitation, which, together with the satisfaction of 
all  conditions  precedent  to  the  effectiveness  of  the  Second 
Amended  Plan  of  Rehabilitation,  including  the  discharge  of  all 
unpaid  policy  claims  of  the  Segregated  Account,  including 
accretion amounts thereon ("Deferred Amounts"), completed the 
restructuring transactions (the "Rehabilitation Exit Transactions") 
announced by Ambac on July 19, 2017.

In exchange for an effective consideration package of 40% cash, 
41%  Secured  Notes  (as  defined  below)  and  12.5%  General 
Account  Surplus  Notes  (as  defined  below),  paid  in  respect  of 
outstanding  Deferred  Amounts  and  General  Account  Surplus

(Dollar Amounts in Thousands, Except Share Amounts)

Notes.  Ambac Assurance received the following benefits as a result 
of the completion of the Rehabilitation Exit Transactions:

•  Satisfaction  and  discharge  of  all  outstanding  Deferred 
Amounts  (including  accretion)  of  the  Segregated Account, 
totaling $3,856,992;

•  Cancellation  of $552,320  in  principal  amount  outstanding, 
plus  accrued  and  unpaid  interest  of  $257,200  thereon,  of 
Ambac  Assurance's  5.1%  surplus  notes  due  2020  (the 
"General Account Surplus Notes"); and

•  An effective discount of 6.5% on Deferred Amounts (applied 
first  against  accretion)  and  on  the  outstanding  amount  of 
principal and accrued and unpaid interest on tendered General 
Account Surplus Notes.

Ambac received $0.91 in principal amount of Secured Notes for 
each $1.00 of Deferred Amounts (including accretion) that it held, 
and provided a $0.09 discount in full satisfaction and discharge of 
its  Deferred Amount  claims.   Ambac  did  not  participate  in  the 
voluntary surplus note exchange offers.  Until the earlier of (i) June 
8, 2020 and (ii) the date on which at least 25% of the principal 
amount  of  General  Account  Surplus  Notes  (other  than  junior 
surplus notes) are no longer outstanding,  Ambac has agreed to 
hold and not sell General Account Surplus Notes (other than junior 
surplus  notes)  which,  as  of  June  30,  2017,  had  an  aggregate  of 
$60,000  of  principal  amount  and  accrued  and  unpaid  interest 
outstanding.

A  newly  formed  special  purpose  entity,  Ambac  LSNI,  LLC 
("Ambac  LSNI")  issued  $2,154,332  of  new  secured  notes  (the 
“Secured  Notes”),  secured  by  all  assets  of  the  special  purpose 
entity,  which  include  a  note  issued  by Ambac Assurance  to  the 
special purpose entity (the "Ambac Note"), which is secured by a 
pledge of Ambac Assurance’s right, title and interest in up to the 
first  $1,400,000  of  proceeds  (net  of  reinsurance)  from  certain 
litigations in which Ambac Assurance seeks redress for breaches 
of representations and warranties and/or fraud related to residential 
mortgage-backed  securitizations  (the  “RMBS  Litigations”).  In 
addition, the Ambac Note is secured by cash and securities having 
a  market  value  of  $209,983  as  of  December 31,  2018.   Ambac 
Assurance also pledged for the benefit of the holders of Secured 
Notes (other than Ambac Assurance) the proceeds of the Secured 
Notes held by Ambac Assurance from time to time, and issued a 
financial guaranty insurance policy to a trustee for the benefit of 
holders of Secured Notes irrevocably guarantying all principal and 
interest payments in respect of the Secured Notes as and when such 
payments become due and owing.

Prior to the Rehabilitation Exit Transactions, Ambac and Ambac 
Assurance owned securities that were insured by Ambac Assurance 
and  allocated  to  the  Segregated  Account.    As  a  result  of  the 
Rehabilitation  Exit Transactions, Ambac  and Ambac Assurance 
received $124,881 and $643,583, respectively, of par amount of 
Secured Notes issued by Ambac LSNI.  The current holdings of 
these secured notes are reported in Investments in the Consolidated 
Balance Sheets at their fair value.

Stipulation and Order

Upon consummation of the Rehabilitation Exit Transactions, the 
Stipulation and Order became effective.  The Stipulation and Order 

includes affirmative covenants, as well as restrictions on certain 
business  activities  and  transactions,  of  Ambac  and  Ambac 
Assurance. The Stipulation and Order has no fixed term and may 
be terminated or modified only with the approval of OCI.  OCI 
reserved the right to modify or terminate the Stipulation and Order 
in a manner consistent with the interests of policyholders, creditors 
and the public generally.

Tier 2 Financing

On  the  effective  date  of  the  Rehabilitation  Exit  Transactions, 
Ambac Assurance  issued  $240,000  of  senior  notes  (the  “Tier  2 
Notes”) secured by Ambac Assurance’s rights, title and interest in 
the  cash  and  non-cash  proceeds  (net  of  reinsurance)  above 
$1,600,000  received  in  connection  with  the  RMBS  Litigations. 
The indenture for the Tier 2 Notes limits certain activities of Ambac 
Assurance  and  its  subsidiaries,  such  as  issuing  indebtedness; 
engaging in mergers and similar transactions; disposing of assets; 
making  restricted  payments;  and  creating  or  permitting  liens 
(among other restrictions and limitations).  The indenture for the 
Tier  2  Notes  includes  certain  allowances  with  respect  to  these 
activities and generally requires the approval of OCI and, in some 
cases,  holders  of  the  Tier  2  Notes,  for  consents,  waivers  or 
amendments.

Bank Settlement Agreement Waiver and Amendment

As part of the Rehabilitation Exit Transactions, Ambac and Ambac 
Assurance received  sufficient  consents  from  holders  of  General 
Account Surplus Notes for a waiver and amendment (the "BSA 
Waiver and Amendment") of the Settlement Agreement. Among 
other  provisions,  the  BSA  Waiver  and  Amendment  includes 
amendments  to  the  Settlement Agreement  that  (i)  eliminate  the 
requirement for Ambac Assurance to have "unaffiliated qualified 
directors" on its Board of Directors; (ii) eliminate the prohibition 
on  new  business  activities;  (iii)  modify  the  restrictions  on  the 
incurrence  of  indebtedness  and  other  material  obligations;  (iv) 
modify the restrictions on liens securing permitted indebtedness; 
(v) modify restrictions applicable to junior surplus notes; and (vi) 
modify restrictions on mergers or similar transactions.  After giving 
effect  to  the  BSA  Waiver  and  Amendment,  the  Settlement 
Agreement  continues  to  limit  certain  activities  of  Ambac 
Assurance  and  its  subsidiaries,  such  as  issuing  indebtedness; 
engaging in mergers and similar transactions; disposing of assets; 
making restricted payments; creating or permitting liens; engaging 
in transactions with affiliates; modifying or creating tax sharing 
agreements; and taking certain actions with respect to surplus notes 
(among  other  restrictions  and  limitations).    The  Settlement 
Agreement  includes  certain  allowances  with  respect  to  these 
activities and generally requires the approval of OCI and, in some 
cases, holders of surplus notes issued pursuant to the Settlement 
Agreement, for consents, waivers or amendments.

Final Decree and Order

On  June  22,  2018,  the  Rehabilitation  Court  entered  the  Final 
Decree  and  Order  discharging 
Insurance 
Commissioner  as  Rehabilitator  and 
the  Special  Deputy 
Commissioner for the Segregated Account and formally closing 
the case that was commenced by OCI in the Rehabilitation Court 
in 2010.

August 2018 AMPS Exchange

At June 30, 2018, Ambac Assurance had 26,411 shares of issued 
and outstanding AMPS with a liquidation preference of $660,275 
(reported  as  noncontrolling  interest  of  $264,110  on  Ambac's 
balance sheet).

On  July  3,  2018, Ambac  and Ambac Assurance  commenced  an 
offer  to  exchange  (the  “AMPS  Exchange”)  all  of  Ambac 
Assurance’s  outstanding  AMPS  for  General  Account  Surplus 
Notes and, from Ambac, cash and warrants to purchase Ambac's 
common stock. Concurrently with the AMPS Exchange, Ambac 
Assurance  solicited  proxies  (each  a  “Proxy”  and  together  the 
“Proxies”)  from  the  holders  of  the AMPS  to  vote  in  favor  of  a 
resolution to be passed at a special meeting (“Special Meeting”) 
of Ambac Assurance’s shareholders (the “Proxy Solicitation”). The 
General Account Surplus Notes offered in the AMPS Exchange 
have the same terms as other outstanding surplus notes of Ambac 
Assurance (other than junior surplus notes). The offering period 
for  the  AMPS  Exchange  expired  on  August  1,  2018  and  the 
transaction closed on August 3, 2018 (the "Settlement Date").

In exchange for each $25 of liquidation preference (i.e., per share), 
AMPS holders received from Ambac Assurance General Account 
Surplus Notes with a total outstanding amount (including accrued 
and unpaid interest thereon through on June 22, 2018 (the "Signing 
Date")) equal to $13.875 (the “Repurchase”).  AMPS holders who 
tendered on or before July 17, 2018, representing 22,096 of the 
AMPS,  also  received  from Ambac  $0.500  in  cash  and  37.3076 
warrants (rounded down to the nearest whole warrant) to purchase 
an equivalent number of shares of common stock of Ambac at an 
exercise  price  of  $16.67  per  share  (the  “AFG  Purchase”  and, 
together with the Repurchase, the “Purchases”).

As a result of the completion of the Purchases, Ambac:

1)  Repurchased 84.4% or 22,296 AMPS with an aggregate 
liquidation preference of $557,400, including $34,650 in 
aggregate liquidation preference in the AFG Purchase;

2)  Captured a nominal discount of approximately $227,000 
(a  discount  of  approximately  $253,000  on  a  fair  market 
value  basis)  on  $557,400  of  the  total  outstanding 
liquidation preference of AMPS; and

3) 

Issued, in aggregate, $212,740 in current principal amount 
of  General Account  Surplus  Notes  with  accrued  interest 
thereon  on  Settlement  Date  of  $98,366,  issued  824,307 
warrants and paid $11,048 in cash.

The  AMPS  are  reported  on  the  balance  sheet  within  non-
controlling interests and are carried at their fair value at the date 
Ambac emerged from bankruptcy in April 2013, which is lower 
than the fair value of the total consideration provided to the AMPS 
holders in the Purchases.  The difference between the fair value of 
consideration provided to AMPS holders and the carrying amount 
of the AMPS was reflected as a reduction to Net income attributable 
to  common  stockholders  in  the  third  quarter  of  2018  for 
approximately $81,686.

Concurrently  with  the  offering  of  the AMPS  Exchange, Ambac 
Assurance launched the Proxy Solicitation to approve (i) for the 
holders of AMPS only, the Purchases and (ii) an amendment to 

Ambac Assurance’s Restated Articles of Incorporation to delete 
Section 7(c) of the Fifth Article, which provided for the purported 
right of holders of AMPS to elect Ambac Assurance directors in 
certain  circumstances  (the  “Charter Amendment”  and  together 
with the Purchases, the “Transactions”). The affirmative vote of 
the  holders  of  at  least  two-thirds  in  aggregate  liquidation 
preference of AMPS was required for the Purchases and the Charter 
Amendment to be operative. Additionally, the affirmative vote of 
at least two-thirds of the outstanding shares of Ambac Assurance 
common stock entitled to vote at the Special Meeting was required 
for the Charter Amendment to be operative.  The Special Meeting 
was held on July 18, 2018, at which the Transactions were duly 
approved.  The  Charter  Amendment  became  effective  on  the 
Settlement Date.

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.  Such  estimates  that  are 
particularly  susceptible  to  change  are  used  in  connection  with 
certain fair value measurements, valuation of loss reserves for non-
derivative insurance policies and the 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.  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. An entity that is deemed the primary beneficiary of a 
VIE is required to consolidate the VIE.  Refer to Note 3. 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, 2018 and 2017 and for the years 
ended  December  31,  2018,  2017  and  2016.  Investments  in 
subsidiaries  are  accounted  for  using  the  equity  method  of 
accounting. 

Investments: 

The Investments - Debt Securities Topic of the ASC requires that 
all debt 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 debt 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 Securities Topic of the ASC. Available-
for-sale debt 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 debt 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  non-VIE  investment  portfolio  also  includes  equity 
interests in pooled investment funds which are accounted for in 
accordance with the Investments - Equity Securities Topic of the 
ASC. Such equity interests 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. 

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. 
Variable Interest Entities. 

Ambac has a formal impairment review process for fixed income 
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 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 amortized cost basis. Ambac accretes the new 
amortized 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.  Prior to 
the  discharge  and  settlement  of  the  Segregated Account's  claim 
obligations  on  February  12,  2018,  the  estimate  of  Ambac's 
Segregated  Account  claim  payments,  including  interest  on 
Deferred  Amounts,  was  an  important  consideration  in  the 
evaluation of other than temporary impairment as such payments 
were at the sole discretion of the Rehabilitator. Refer to Note 1.

Segregated Account  and  the  Segregated Account  Rehabilitation

Proceedings. 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, 2018 and 2017, was 2.7%. and 2.5%, respectively, 
and  the  weighted  average  period  of  future  premiums  used  to 
estimate the premium receivable at December 31, 2018 and 2017, 
was 8.7 years and 9.8 years, respectively.

Insured obligations consisting of homogeneous pools for which 
Ambac uses expected future premiums to estimate the premium 
receivable  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  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, 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. 

•  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 under 
the  fair  value  option  election  with  changes  in  fair  value 
recorded in Income (loss) on variable interest entities on the 
Consolidated Statements of Total Comprehensive Income.

AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES

(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. 

•  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 
within  Net  gains  (losses)  on  derivative  contracts  on  the 
Consolidated Statements of Total Comprehensive Income.  

•  Ambac maintains a portfolio consisting primarily of interest 
rate  swaps  and  futures  contracts  to  economically  hedge 
interest rate risk in the financial guarantee and investment 
portfolios.  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 
all  interest  rate  derivatives  are  recorded  within  net  gains 
(losses)  on  derivative  contracts  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.  Variation 
payments  on  centrally  cleared  swaps  and  futures  contracts  are 
considered settlements of the associated derivative balances and 
are reflected as a reduction to derivative liabilities or assets on the 
Consolidated Balance Sheets.  For other derivatives, 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 and are included in "Other assets" on 
the Consolidated Balance Sheets.  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. 

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.  The  carrying 
values  of  our  financial  guarantee  insurance  and  reinsurance 
contracts continue to be reported and measured in accordance with 

their  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 support the obligations of the consolidated VIEs. 

Loss and Loss Expenses: 

The loss and loss expense reserve (“loss reserve”) policy 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 above. 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 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  and  (ii)  accrued  interest  on  Deferred 
Amounts (generally at an effective rate of 5.1%.) as required 
by the Segregated Account Rehabilitation Plan that became 
effective on June 12, 2014.  Unpaid claims are measured based 
on  the  cost  of  settling  the  claims,  which  is  principal  plus 
accrued  interest.  As  a  result  of  the  Rehabilitation  Exit 
Transactions, as of February 12, 2018, all unpaid claims for 
policies  allocated  to  the  Segregated  Account  were  fully 
satisfied and discharged.  Subsequent to the Rehabilitation 
Exit Transactions, unpaid claims are no longer included as a 
component of loss reserves.  Refer to Note 1. Background and 
Business Description for further discussion of the Segregated 
Account rehabilitation.  

•  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,  which  is  discussed  further  in  the 
“RMBS  Representation 
and  Warranty  Subrogation 
Recoveries”  section  below,  (iii)  excess  spread  within  the 
underlying transaction's cash flow structure, and (iv) other 
subrogation recoveries, including other litigation recoveries 
and expected receipts from third parties within the underlying 
transaction's  cash  flow  structure.    Ambac’s  approach  to 
resolving  disputes 
involving  contractual  breaches  by 
transaction  sponsors  or  other  third  parties  has  included

(Dollar Amounts in Thousands, Except Share Amounts)

negotiations  and/or  pursuing  litigation.  Ambac  does  not 
estimate recoveries for litigations where its sole claim is for 
fraudulent inducement, 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.  

from  period 

to  period  and  update 

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 
ongoing review of the financial guarantee credit portfolio. Active 
surveillance  of  the  insured  portfolio  enables  Ambac’s  Risk 
Management Group ("RMG") to track credit migration of insured 
obligations 
internal 
classifications  and  credit  ratings  for  each  transaction.  Non-
adversely  classified  credits  are  assigned  a  Class  I  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  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  RMG  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 
fundamental  credit  quality.  Through  ongoing 
surveillance, Ambac may also designate Class I credits into one or 
more of the following categories:

the 

•  Survey list - credits that may lack information or demonstrate 

a weakness but further deterioration is not expected.

•  Watch list - credits that demonstrate the potential for future 
material adverse development due to such factors as long-
term uncertainty about a particular sector, a certain structural 
element or concern related to the issuer or transaction or the 
overall financial and economic sustainability.

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 certain of 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 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  RMG  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 
(e.g., 
for 
potential 
commutations). 

remediation 

additional 

activities 

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 RMG 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  and  tools  to  project  future  losses  and  resultant  claim 
payment  estimates. We  utilize  cash  flow  models  for  residential 
mortgage-backed  (RMBS),  student  loan,  Puerto  Rico  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 
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, Ambac’s ability 
to  execute  a  potential  settlement  (i.e.,  commutation)  of  the 
insurance  policy,  including  the  impact  on  future  installment 
premiums, and/or other restructuring scenarios. 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. 

loss  estimate 

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 and warranties with 
respect to loan characteristics, the absence of borrower fraud in 
the underlying loan pools and 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.    Ambac  or  its  counsel  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) high 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 
the 
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 loans 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

(Dollar Amounts in Thousands, Except Share Amounts)

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. 

While the obligation by sponsors to repurchase loans with material 
breaches is clear, generally the sponsors have not 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 
above-mentioned,  detailed 
the 
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.  For example, Ambac received a significant payment 
in 2016 from JP Morgan to settle RMBS-related litigation. As a 
result of these factors, we do not make significant adjustments to 
our estimated subrogation recoveries with respect to the credit risk 
of these sponsors or their successors. 

Our  ability  to  realize  RMBS  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  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.  Failure to realize RMBS R&W subrogation recoveries 
for  any  reason  or  the  realization  of  RMBS  R&W  subrogation 
recoveries  materially  below  the  amount  recorded  on  Ambac's 
consolidated balance sheet would have a material adverse effect 
on our results of operations and financial condition and may result 
in adverse consequences such as impairing the ability of Ambac 
Assurance  to  honor  its  financial  obligations;  the  initiation  of 
rehabilitation  proceedings  against Ambac Assurance;  decreased 
likelihood  of  Ambac  Assurance  delivering  value  to  Ambac, 
through dividends or otherwise; and a significant drop in the value 
of securities issued or insured by Ambac or Ambac Assurance.

The  approach  used  to  estimate  RMBS  R&W  subrogation 
recoveries is based on obtaining loan files from the original pool 
and conducting loan file re-underwriting to derive a breach rate to 
be extrapolated to determine an estimated repurchase obligation. 
We  limit  the  estimated  repurchase  obligation  by  ever-to-date 
incurred losses.

Multiple  probability-weighted  scenarios  are  developed  by 
applying various  realization factors  to the  estimated repurchase 
obligation.  The  realization  factors  in  these  scenarios  reflect 
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) assessment of 
the  strength  of  the  specific  case  and  (iii)  experience  in  settling 
similar claims. The probability weightings are developed based on 
the unique facts and circumstances for each transaction. The sum

the 
undiscounted RMBS R&W subrogation recovery, which is then 
discounted using a factor derived from a risk-free discount rate

recovery.  Discount factors are updated for the current risk-free 
rate each reporting period.

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  or  redeems  its  long-term  debt,  such  repurchases  or 
redemptions  may  be  settled  for  an  amount  different  than  the 
carrying  value  of  the  obligation.  Any  difference  between  the  
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.

Noncontrolling Interest:

At December 31, 2018 and 2017, Ambac Assurance had 4,115 and 
26,411 shares of issued and outstanding AMPS with a liquidation 
preference of $102,875 and $660,275  (reported as noncontrolling 
interest  of  $41,150  and  $264,110  on  Ambac's  balance  sheet), 
respectively.    The  auction  occurs  every  28  days.  Due  to  the 
dislocation in the auction rate markets and the Company’s financial 
condition, the dividend rate on the auction market preferred has 
continuously been reset at the maximum rate of one-month LIBOR 
plus 200 basis points. 

Under the terms of the preferred stock, dividends may not be paid 
on the common stock of Ambac Assurance unless all accrued and 
unpaid  dividends  on  the  preferred  stock  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 preferred stock become cumulative until the date 
that all accumulated and unpaid dividends have been paid on the 
preferred stock.  Ambac Assurance has not paid dividends on its 
preferred stock since 2010.

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.  

Incentive Compensation: 

Incentive compensation is a key component of our compensation 
strategy. Our incentive compensation awards generally have two 
components: short term incentive compensation (consisting of an 
annual cash bonus and awards of deferred stock units for certain 
officers) and long term incentive plan awards (consisting of cash 
awards  and  restricted  and  performance  stock  units).    Annual 
decisions  with  regard  to  incentive  compensation  are  generally 
made in the first quarter of each year and are based on Company 
performance and individual and business unit performance of the 
prior year.  

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 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.

Prior to the adoption of ASU 2016-09 (as noted below), Ambac 
recognized  compensation  costs  for  all  equity  classified  awards 
granted  at  fair  value  with  an  estimation  of  forfeitures  for  all 

unvested shares. As a result of the adoption of ASU 2016-09 in 
2017,  Ambac  recognizes  compensation  costs  for  all  equity 
classified awards granted at fair value and records forfeitures for 
unvested shares only when they occur.

The types of awards granted to employees are as follows:

•  Deferred stock units granted vest upon grant and will settle 
and convert to Ambac common stock annually over a two-
year period (50% on the first anniversary of the grant date 
and 50% on the second anniversary of the grant date).  The 
fair  value  of  these  grants  is  recognized  as  compensation 
expense on the date of grant since no future service is required.

•  Restricted stock units granted only require future service and 
accordingly  the  respective  fair  value  is  recognized  as 
compensation expense 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 recognized as 
compensation  expense  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. 

Foreign Currency:

Financial statement accounts expressed in foreign currencies are 
translated  into  U.S.  dollars  in  accordance  with  the  Foreign 
Currency Matters Topic of the ASC. The functional currencies of 
Ambac's subsidiaries are the local currencies of the country where 
the respective subsidiaries are based, which are also the primary 
operating environments in which the subsidiaries operate. 

Foreign  currency  translation:  Functional  currency  assets  and 
liabilities of Ambac’s foreign subsidiaries are translated into U.S. 
dollars using exchange rates in effect at the balance sheet dates and 
the  related  translation  adjustments,  net  of  deferred  taxes,  are 
included as a component of Accumulated Other Comprehensive 
Income in Stockholders' Equity.  Functional currencies operating 
results  of  foreign  subsidiaries  are  translated  using  average 
exchange rates.

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 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 14. 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 and 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  used  for  basic  earnings  per 
share plus all potential dilutive common shares outstanding during 
the  period.   All  potential  dilutive  common  shares  outstanding 
consider common stock deliverable pursuant to warrants issued in 
2013, vested and unvested options, unvested restricted stock units 
and unvested performance stock units granted under employee and 
director compensation plans.

Foreign currency transaction gains/(losses) are primarily the result 
of remeasuring Ambac UK's assets and liabilities denominated in 
currencies other than its functional currency, primarily the U.S. 
dollar and the Euro.

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). Current tax assets and 
liabilities are recognized for taxes refundable or payable for the 
current year. 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 current and 
deferred  tax  assets  and  liabilities  of  a  change  in  tax  rates  is 
recognized  in  the  period  that  includes  the  enactment  date.  In 
December 2017, the Tax Cut and Jobs Act ("TCJA") was enacted 
that introduced significant changes that impact U.S. corporate tax 
rates,  business-related  exclusions,  and  deductions  and  credits 
effective January 1, 2018. As such, we incorporated the effects of 
the TCJA in our current and deferred tax evaluation for the year 
ended December 31, 2017.  

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.

Recently Adopted Accounting Standards:

Effective  January  1,  2018,  Ambac  adopted  the  following 
accounting standards:

Stock Compensation--Scope of Modification Accounting

In May 2017, the FASB issued ASU 2017-09, Compensation-Stock 
Compensation (Topic 718) - Scope of Modification Accounting.  
The ASU provides guidance about which changes to the terms or 
conditions of a share-based payment award require an entity to 
the 
apply  modification  accounting. 
modification accounting guidance if the value, vesting conditions 
or  classification  of  the  award  changes.    The  current  disclosure 
requirements in Topic 718 apply regardless of whether an entity is 
required to apply modification accounting under the amendments 
in this ASU.  The adoption of this ASU did not have an impact on 
Ambac's financial statements.

  Entities  will  apply 

Net Periodic Pension and Postretirement Costs

In  March 2017, the FASB issued ASU 2017-07, Compensation-
Retirement Benefits (Topic 715) - Improving the Presentation of 
Net Periodic Pension Cost and Net Periodic Postretirement Benefit 
Cost.  The objective of the ASU is to increase transparency in the 
reporting  of  net  pension  cost  and  net  postretirement  cost 
(collectively "net benefit cost"). The ASU requires that the service 
cost component of net benefit cost be reported on the same line 
item as other compensation costs arising from services rendered 
by employees.  It further requires that the other components of net 
benefit costs (i.e. interest costs, amortization of prior service cost, 
etc.) be presented separately from the service cost component and 
outside the subtotal of income from operations, if one is presented. 
Prior to adoption of this ASU, Ambac reported all postretirement 
costs  in  Operating  expenses  on  the  Consolidated  Statements  of 
Total  Comprehensive  Income  (Loss).  Adoption  of  this  ASU 
resulted in a reclassification of other non-service related amounts 
from Operating expenses to Other income (expense) resulting in 
an  increase  to  both  Operating  expenses  and  Other  income 
(expense) of $920 and $625 for the years ended December 31, 2017 
and 2016, respectively.

Restricted Cash

In November 2016, the FASB issued ASU 2016-18, Statement of 
Cash Flows (Topic 230) - Restricted Cash. Prior to the effective 
date of this ASU, GAAP did 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 ASU 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.   Adoption  of  this ASU  resulted  in  the  inclusion  of 
restricted  cash  activity  related  to  consolidated  VIEs  on  the 
Consolidated Statements of Cash Flows for all periods presented.  

Also  refer  to  the  Supplemental  Disclosure  of  Cash  Flow 
Information  section  above  for  the  reconciliation  of  cash,  cash 
equivalents,  and  restricted  cash  reported  on  the  Consolidated 
Statement of Position that sum to the total of the same such amounts 
on the Consolidated Statements of Cash Flows.

Income Taxes

In October 2016,  the FASB issued ASU 2016-16, Income Taxes 
(Topic  740)  -  Intra-Entity  Transfers  of  Assets  Other  Than 
Inventory. Prior to  the effective date of this ASU, GAAP prohibited 
the  recognition  of  current  and  deferred  income  taxes  for 
intercompany transfers of assets until the asset had been sold to an 
outside  party.  The  ASU  requires  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. The adoption of this ASU did 
not have an 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  are  potentially  relevant  to Ambac  include  the 
following:

•  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.

After  further  evaluating  the  potentially  relevant  items,  we 
determined the adoption of this ASU did not have an impact on 
Ambac's financial statements.

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) requires equity investments with readily determinable 
fair values to be measured at fair value with changes recognized 
in net income; ii) simplifies the impairment assessment of equity 
securities  without  readily  determinable  fair  values  using  a 
qualitative approach; iii) eliminates disclosure of the method and 
significant assumptions used to fair value instruments measured 
at amortized cost on the balance sheet; iv) requires the 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,  requires  the  portion  of  the  fair  value 
change related to instrument-specific credit risk, to be separately 
reported in other comprehensive income; vi) requires 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) clarifies 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. 

With respect to item v) above, Ambac has elected the fair value 
option for all VIE financial liabilities.  For these VIE liabilities this 
ASU has resulted in a cumulative-effect reclassification of $2,900, 
net  of  deferred  tax  of  $590,  between  Retained  earnings  and 
Accumulated other comprehensive income, with no net change to 
Total stockholders' equity as of January 1, 2018.  Going forward, 
the  instrument-specific  credit  risk  of  fair  value  changes  in VIE 
liabilities will be reported in Accumulated other comprehensive 
income  in  accordance  with  this ASU,  with  all  other  fair  value 
changes continuing to be reported through net income. There was 
no material impact on Ambac's financial statements for the other 
provisions of this ASU.

Revenue recognition

In  May  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. As this ASU does not apply to insurance contracts and 
most financial instruments, management determined there was no 
impact on Ambac's financial statements.

Future Application of Accounting Standards:

VIE Related Party Guidance

In October 2018, the FASB issued ASU 2018-17, Consolidation 
(Topic 810) - Targeted Improvements to Related Party Guidance 
for Variable Interest Entities. To determine whether a decision-
making  fee  is  a  variable  interest,  under  the  new  guidance  a 
reporting  entity  must  consider  indirect  interests  held  through 
related parties under common control on a proportional basis rather 
than  as  a  direct  interest  in  its  entirety  (as  currently  required  in 
GAAP).  These  amendments  create  alignment  between 
determining whether a decision making fee is a variable interest 

and determining whether a reporting entity within a related party 
group is the primary beneficiary of a VIE. ASU 2018-17 is effective 
for  fiscal  years,  and  interim  periods  within  those  fiscal  years, 
beginning after December 15, 2019, with early adoption permitted. 
Ambac will adopt this ASU on January 1, 2020. The ASU is not 
expected  to  have  a  consequential  impact  on Ambac's  financial 
statements. 

Cloud Computing Arrangement Service Contracts

In August  2018,  the  FASB  issued ASU  2018-15,  Intangibles—
Goodwill and Other— Internal-Use Software (Subtopic 350-40) - 
Customer’s Accounting  for  Implementation  Costs  Incurred  in  a 
Cloud Computing Arrangement That Is a Service Contract. The 
new  guidance  requires  a  customer  in  a  cloud  computing 
arrangement  that  is  a  service  contract  to  capitalize  certain 
implementation  costs  as  if  the  arrangement  was  an  internal-use 
software project. The internal-use software guidance requires the 
capitalization of certain costs incurred only during the application 
development  stage  (e.g.,  costs  of  integration  with  on-premises 
software,  coding,  configuration,  customization).  That  guidance 
also  requires  entities  to  expense  costs  during  the  preliminary 
project  and  post-implementation  stages  (e.g.,  costs  of  project 
planning,  training,  maintenance  after  implementation,  data 
conversion) as they are incurred.  ASU 2018-15 is effective for 
fiscal  years,  and  interim  periods  within  those  fiscal  years, 
beginning after December 15, 2019, with early adoption permitted. 
The ASU may be applied either retrospectively or prospectively 
to  all  implementation  costs  incurred  after  the  date  of  adoption. 
Ambac will adopt this ASU on January 1, 2020. The ASU is not 
expected  to  have  a  consequential  impact  on Ambac's  financial 
statements.

Defined Benefit and Other Postretirement Plans Disclosures

In August 2018, the FASB issued ASU 2018-14, Compensation - 
Retirement Benefits - Defined Benefit Plans - General (Subtopic 
715-20)  -  Disclosure  Framework  -  Changes  to  the  Disclosure 
Requirements  for  Defined  Benefit  Plans.  The  ASU  modifies 
various  disclosure  requirements  for  employers  that  sponsor 
defined  benefit  pension  or  other  postretirement  plans.  Relevant 
disclosures that will be removed are: i) amounts in accumulated 
other  comprehensive  income  expected  to  be  recognized  as  net 
periodic benefit cost over the next fiscal year, and ii) the effects of 
a one percentage point change in assumed health care cost trend 
rates  on  the  (a)  aggregate  of  the  service  and  interest  cost 
components  of  the  net  periodic  pension  cost  and  (b)  benefit 
obligation  for  postretirement  healthcare  benefits.  Relevant 
disclosures that will be added are an explanation of the reasons for 
significant  gains  and  losses  related  to  changes  in  the  benefit 
obligations  for  the  period.   ASU  2018-14  is  effective  for  fiscal 
years  ending  after  December  15,  2020,  with  early  adoption 
permitted.    The  modified  disclosures  must  be  applied  on  a 
retrospective  basis  for  all  periods  presented.    Ambac  has  not 
determined whether it will early adopt this ASU.  The ASU is not 
expected  to  have  a  consequential  impact  on Ambac's  financial 
statements.

Fair Value Measurement Disclosures

In  August  2018,  the  FASB  issued  ASU  2018-13,  Fair  Value 
Measurement (Topic 820) - Disclosure Framework - Changes to 
the Disclosure Requirements for Fair Value Measurement.  The 

| Ambac Financial Group, Inc.   87   2018 FORM 10-K |

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

ASU  modifies  various  disclosure  requirements  on  fair  value 
measurements.  Relevant  disclosures  that  will  be  removed, 
modified and added are as follows:

•  Removals: 1) Amount of and reasons for transfers between 
Level 1 and Level 2 of the fair value hierarchy, 2) Policy for 
timing of transfers between levels, and 3) Valuation processes 
for Level 3 fair value measurements. 

•  Modifications:  1)  For  investments  in  certain  entities  that 
calculate net asset value, disclosures are only required for the 
timing of liquidation of an investee's assets and the date when 
restrictions from redemption might lapse, only if the investee 
has  communicated  the  timing  to  the  reporting  entity  or 
publicly  announced  it,  and  2)  Clarification  that  the 
measurement  uncertainty  disclosure  is  to  communicate 
information about the uncertainty in measurement as of the 
reporting date and not possible future changes.

•  Additions: 1) Changes in unrealized gains and losses for the 
period included in other comprehensive income ("OCI") for 
recurring Level 3 fair value measurements held at the end of 
the reporting period and 2) Range and weighted average of 
significant unobservable inputs used to develop Level 3 fair 
value  measurements. Alternatively,  an  entity  may  disclose 
other  quantitative  information  (such  as  the  median  or 
arithmetic average) if it determines that it is a more reasonable 
and rational method to reflect the distribution of unobservable 
inputs used.

ASU  2018-13  is  effective  for  fiscal  years,  and  interim  periods 
within those fiscal years, beginning after December 15, 2019, with 
early  adoption  permitted.    Disclosure  amendments  related  to 
changes in unrealized gains and losses included in OCI for level 
3  instruments,  the  range  and  weighted  average  of  significant 
unobservable inputs, and the narrative description of measurement 
uncertainty  should  be  applied  prospectively  only  for  the  most 
recent  interim  or  annual  period  presented.   All  other  disclosure 
amendments  should  be  applied  retrospectively  to  all  periods 
presented. Ambac has not determined whether it will early adopt 
this ASU.  The ASU is not expected to have a consequential impact 
on Ambac's financial statements.

Equity-linked Instruments with Down Round Features

In July 2017, the FASB issued ASU 2017-11, Earnings Per Share 
(Topic 260) and Derivatives and Hedging (Topic 815) - Accounting 
for  Certain  Financial  Instruments  with  Down  Round  Features.  
Equity-linked  instruments,  such  as  warrants  and  convertible 
instruments  may  contain  down  round  features  that  result  in  the 
strike  price  being  reduced  on  the  basis  of  the  pricing  of  future 
equity offerings. Under the ASU, a down round feature will no 
longer  require  a  freestanding  equity-linked  instrument  (or 
embedded conversion option) to be classified as a liability that is 
remeasured  at  fair  value  through  the  income  statement  (i.e. 
marked-to-market).  However, other features of the equity-linked 
instrument  (or  embedded  conversion  option)  must  still  be 
evaluated to determine whether liability or equity classification is 
appropriate.    Equity  classified  instruments  are  not  marked-to-
market.  For earnings per share ("EPS") reporting, the ASU requires 
companies to recognize the effect of the down round feature only 
when it is triggered by treating it as a dividend and as a reduction 
of income available to common stockholders in basic EPS. The 

amendments  in  this ASU  are  effective  for  all  entities  for  fiscal 
years, and interim periods within those fiscal years, beginning after 
December  15,  2018.  Early  adoption  is  permitted,  including 
adoption in any interim period.  Ambac will adopt this ASU on 
January 1, 2019 and it will not have a consequential impact on 
Ambac's financial statements.

Premium Amortization on Callable Debt Securities

In  March  2017,  the  FASB  issued ASU  2017-08,  Receivables-
Nonrefundable Fees and Other Costs (Subtopic 310-20) - Premium 
Amortization on Purchased Callable Debt Securities.  The ASU 
shortens the amortization period for the premium on callable debt 
securities to the earliest call date.  Under current GAAP, a reporting 
entity generally amortizes the premium as a yield adjustment over 
the contractual life (i.e. maturity) of the debt security and if that 
debt security is called, the entity would record a loss equal to the 
unamortized premium.  The ASU does not change the accounting 
for callable debt securities held at a discount, which will continue 
to be amortized to maturity.  ASU 2017-08 is effective for fiscal 
years  beginning  after  December  15,  2018,  and  interim  periods 
within those fiscal years, with early adoption permitted.  The ASU 
must  be  applied  on  a  modified  retrospective  basis  through  a 
cumulative-effect adjustment directly to retained earnings as of the 
beginning of the period of adoption. Ambac will adopt this ASU 
on January 1, 2019 and it will not 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 debt 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, with early adoption permitted. Ambac 
will  adopt  this ASU  on  January  1,  2020  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 

| Ambac Financial Group, Inc.   88   2018 FORM 10-K |

(Dollar Amounts in Thousands, Except Share Amounts)

instruments  not  already  using  this  model  and  identifying  and 
documenting  accounting  process  changes,  including  related 
controls.

Leases

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 
842). This ASU was subsequently amended by ASU 2016-02, Land 
Easement  Practical  Expedient;  ASU  2010-10,  Codification 
Improvements 
to  Topic  842;  ASU  2018-11,  Targeted 
Improvements;  and ASU 2018-20, Narrow-Scope Improvements 
for Lessors (collectively the "New  Lease Standard"). The primary 
difference  between  current  U.S.  GAAP  and  the  New  Lease 
Standard is the recognition of lease assets and lease liabilities for 
those leases classified as operating leases with a term longer than 
12 months.  For those operating leases, a lessee is required to: 1) 
recognize  a  right-of-use  asset  ("ROU")  and  a  lease  liability, 
initially measured at the present value of the lease payments, on 
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. For leases classified as 
finance leases under the New Lease Standard, the balance sheet 
presentation and expense recognition pattern is similar to capital 
leases under current GAAP.  

The New Lease Standard is effective for fiscal years beginning 
after December 15, 2018, including interim periods within those 
fiscal years. Under the transition guidance, a reporting entity must 
use a modified retrospective approach and may choose to initially 
apply the New Lease Standard either at (1) the beginning of the 
earliest comparative period presented, which is January 1, 2017 or 
(2) its effective date, which is January 1, 2019 . If a reporting entity 
chooses  the  first  option  it  must  recast  its  comparative  period 
financial statements and provide disclosures for those comparative 
periods.  Ambac has chosen the second option and will initially 
apply the New Lease Standard on January 1, 2019. Consequently 
financial information and disclosures will not be provided for dates 
and periods prior to January 1, 2019.   

There are a number of optional practical expedients that can be 
elected at transition. We expect to elect the ‘package of practical 
expedients’,  which  permits  us  not  to  reassess  under  the  new 
standard  our  prior  conclusions  about  lease  identification,  lease 
classification and initial direct costs. We do not expect to elect the 
use-of-hindsight  or  the  practical  expedient  pertaining  to  land 
easements; the latter not being applicable to us.

We do not expect that the New Lease Standard will have a material 
effect on our financial statements. While we continue to assess all 
of the effects of adoption, we currently believe the most significant 
effects relate to (1) the recognition of new ROU assets and lease 
liabilities  on  our  balance  sheet  for  our  office  and  equipment 
operating  leases  and  (2)  providing  significant  new  disclosures 
about our leasing activities. We do not expect a significant change 
in our leasing activities between now and adoption.

On  adoption,  we  currently  expect  to  recognize  lease  liabilities 
ranging from $15,000 to $25,000, with corresponding ROU assets 
within a similar range.

The New Lease Standard also provides practical expedients for a 
reporting entity’s ongoing accounting. We currently expect to elect 
the  short-term  lease  recognition  exemption  for  all  leases  that 
qualify. For those leases that qualify for that exemption, we will 
not recognize ROU assets or lease liabilities, and this includes not 
recognizing ROU assets or lease liabilities for existing short-term 
leases of those assets in transition. We also currently expect to elect 
the  practical  expedient  to  not  separate  lease  and  non-lease 
components for all of our leases. 

Other  significant  implementation  matters  we  are  currently  
addressing are identifying and documenting accounting process 
changes, including related controls.

VARIABLE INTEREST ENTITIES

Ambac,  with  its  subsidiaries,  has  engaged  in  transactions  with 
variable interest entities ("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 notes to 

investors for various purposes; and

•  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 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. 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 control rights that enable Ambac to remediate losses. 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  certain 
liabilities  (and  in  some  cases  certain  assets).    As  further 
described  below,  Ambac  consolidated  certain  FG  VIEs 
because  we  also  had  the  power  to direct  the  activities  that 
most significantly impact the VIE’s economic performance 
due  to  either:  (i) the  transaction  experiencing  deterioration 
and breaching performance triggers, giving Ambac the ability 
to  exercise  certain  control  rights  or  (ii)  the  transaction  not 
experiencing deterioration, however due to the passive nature 
of the VIE, Ambac's contingent control rights upon a future 
breach of performance triggers is considered to be the power 
over  the  most  significant  activity.  FG  VIEs  which  are 
consolidated include recourse liabilities and, in some cases, 
may include non-recourse liabilities. FG VIEs' liabilities that 
are insured by the Company are with recourse, because the

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

Company guarantees the payment of principal and interest to 
the extent there is a shortfall in the FG VIEs' assets. FG VIEs' 
liabilities that are not insured by the Company are without 
recourse,  because  the  payment  of  principal  and  interest  of 
these liabilities is wholly dependent on the performance of 
the FG VIEs' assets. The Company’s exposure to consolidated 
FG  VIEs  is  limited  to  the  financial  guarantees  issued  for 
recourse liabilities and any additional variable interests held 
by Ambac. 

•  A VIE is deconsolidated in the period that Ambac no longer 
has such control rights, which could occur in connection with 
the execution of remediation activities on the transaction or 
amortization of insured exposure, either 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. 

•  Ambac  has  elected  the  fair  value  option  for  all  FG  VIE 
liabilities  which  are 
financial 
financial  assets  and 
consolidated.  The total fair value changes in the  financial 
assets of such FG VIEs are reported within Income (loss) on 
variable interest entities in the  Consolidated Statements of 
Total  Comprehensive  Income  (Loss).  Prior  to  January  1, 
2018, the total fair value changes in the financial liabilities 
of such FG VIEs were also reported within Income (loss) on 
variable interest entities. As further described in Note 2. Basis 
of Presentation and Significant Accounting Policies, effective 
January 1, 2018, Ambac adopted ASU 2016-01. Under this 
ASU, for financial liabilities where fair value option has been 
elected, the portion of the total change in fair value caused 
by changes in the instrument-specific credit risk is presented 
separately in Other comprehensive income (loss).

•  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 
the  Consolidated  Statements  of  Total 
entities  on 
Comprehensive Income (Loss).

•  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.

In connection with the exit from rehabilitation of the Segregated 
Account, as further described in Note 1. Background and Business 
Description,  Ambac evaluated the consolidation of certain VIEs. 
Under the Stipulation and Order, the OCI retained the authority 
requiring Ambac Assurance to obtain their approval with respect 
to the exercise of certain control rights in connection with policies 
that  had  previously  been  allocated  to  the  Segregated Account.  
Accordingly, Ambac did not consolidate any additional VIEs as a 
result of the Segregated Account's exit from rehabilitation. 

As  of  December 31,  2018  consolidated  FG  VIE  assets  and 
liabilities relating to 7 consolidated entities were $7,093,309 and 
$6,981,244, respectively.  As of December 31, 2017, consolidated 
FG VIE assets and liabilities relating to 11 consolidated entities 
were  $14,500,507  and  $14,366,434, 
respectively.  As  of 
December 31, 2018, seven and zero consolidated FG VIEs related 
to  transaction  insured  by  Ambac  UK  and  Ambac  Assurance, 
respectively.  As  of  December 31,  2017,  and  eight  and  three 
consolidated FG VIEs related to transaction insured by Ambac UK 
and Ambac Assurance, respectively.  As of December 31, 2018,  
FG VIE assets and liabilities of $7,093,309 and $6,981,244, and 
as  of  December 31,  2017,  FG  VIE  assets  and  liabilities  of 
$14,160,152 and $14,026,704 related to transactions guaranteed 
by Ambac UK.  The remaining balance of consolidated FG VIE 
assets  and  liabilities  at  December  31,  2017  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  these  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 four, one and one VIEs for the years ended 
December  31,  2018,  2017  and  2016,  respectively.   These VIEs 
were deconsolidated as a result of guaranteed bond retirements or 
loss  mitigation  activities  that  eliminated  or  reduced  Ambac's 
control rights that previously required Ambac to consolidate these 
entities.    During  2018,  one  deconsolidation  was  related  to 
guaranteed bond retirement and three deconsolidations were due 
to  loss  mitigation  activities  and  resulted  in  the  gains  on 
deconsolidation noted in the above table.  The 2018 balance sheet 
impact  of  these  deconsolidations  were  a  decline  to  total 
consolidated assets and liabilities by $6,619,857 and $6,599,925 
from  December  31,  2017 
to  December  31,  2018.  The 
deconsolidations  occurring  in  2017  and  2016  were  related  to 
guaranteed bond retirements which resulted in no gain or loss.

(1)  Maximum exposure to loss represents the maximum future payments of principal and interest on insured obligations and derivative contracts plus Deferred 
Amounts and accrued and unpaid interest thereon. Ambac’s maximum exposure to loss does not include the benefit of any financial instruments (such as 
reinsurance or hedge contracts) that Ambac may utilize to mitigate the risks associated with these variable interests.

(3) 

Insurance assets represent the amount recorded in “Premium receivables” and “Subrogation recoverable” for financial guarantee contracts on Ambac’s 
Consolidated Balance Sheets.

Insurance liabilities represent the amount recorded in “Loss and loss expense reserves” and “Unearned premiums” for financial guarantee contracts on 
Ambac’s Consolidated Balance Sheets.

(4)  Net derivative assets (liabilities) represent the fair value recognized on credit derivative contracts and interest rate swaps on Ambac’s Consolidated Balance 

Sheets.

(5)  On February 12, 2018, Deferred Amounts and Interest Accrued on Deferred Amounts in the amount of $3,000,158 and $856,834, respectively were settled. 

This settlement impacted both insurance assets and insurance liabilities in the table above.

Ambac Sponsored VIEs:

Consolidated VIEs:

In July 2015, Ambac Assurance entered into a secured borrowing 
transaction (the "Secured Borrowing") 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).  Although the Securities 
were legally sold to the Trust, the Securities remained in Invested 
assets on the Consolidated Balance Sheets until they were sold to 
redeem  the  outstanding  Notes.    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 was payable monthly at an annual rate of one 
month  LIBOR  +  2.8%.    Both  the  Trust  and  the  Issuer  were 
consolidated VIEs because Ambac Assurance was involved in their 
design and holds a significant amount of the beneficial interests 
issued by the VIEs and guaranteed the assets held by the VIEs. On 
June 22, 2018, Ambac Assurance exercised its right to terminate 
this  structure  though  its  right  to  sell  a  sufficient  quantity  of 
Securities to redeem the remaining outstanding Notes of the Issuer 
at par plus accrued interest. Accordingly, proceeds from the sale 
of Securities were used to redeem the outstanding Notes. VIE debt 
outstanding  to  third  parties  under  this  secured  borrowing 
transaction had a carrying value of $0 and $73,993 as of December 

31,  2018  and  2017,  respectively,  and  is  reported  in  Long-Term 
Debt on the Consolidated Balance Sheets.

Non-Consolidated VIEs:

A subsidiary of Ambac transferred financial assets to a VIE. The 
business  purpose  of  this  entity  was  to  provide  certain  financial 
guarantee clients with funding for their debt obligations. This VIE 
was established as a separate legal entity, demonstrably distinct 
from Ambac and that Ambac, its affiliates or its agents could not 
unilaterally  dissolve.  The  permitted  activities  of  this  entity  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.  Ambac does not consolidate this 
entity  because Ambac Assurance’s  policies  issued  to  this  entity 
were allocated to the Segregated Account and, as discussed above, 
the exercise of related control rights in such policies remain subject 
to OCI approval under the Stipulation and Order. Ambac elected 
to account for its equity interest in this entity 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 this entity 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 this entity. At December 31, 2018 and 
2017  the  fair  value  of  this  entity  was  $4,516  and  $5,979, 
respectively,  and  is  reported  within  Other  assets  on  the 
Consolidated Balance Sheets.

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

•  Total principal amount of debt outstanding was $393,010 and 
$420,600 at December 31, 2018 and 2017, respectively. In 
each  case, Ambac  sold  assets  to  this  entity. The  assets  are 
composed  of  utility  obligations  with  a  weighted  average 
rating of BBB+ at December 31, 2018 and weighted average 
life of 2.1 years.  The purchase by this entity of financial assets 
was financed through the issuance of 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 
entity  for  economic  hedging  purposes  only.  Derivative 
positions were established at the time MTNs were issued to 
purchase financial assets. As of December 31, 2018 Ambac 
Assurance had financial guarantee insurance policies issued 
for  all  assets,  MTNs  and  derivative  contracts  owned  and 
outstanding by the entity.

•  Insurance premiums paid to Ambac Assurance by this entity 
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 
(Loss).  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.

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 and an owner trust certificate, which represents Ambac's 
right to residual cash flows from the junior surplus note.  Ambac 
does  not  consolidate  the  VIE  since  it  does  not  have  a  variable 
interest in the trust.  Ambac reports its owner trust certificate 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 (Loss).  
The equity investment had a carrying value of $40,168 and $34,941
as of December 31, 2018 and 2017, respectively.  Additionally, at 
December 31, 2018 and 2017 Ambac held $0 and $35,000 of the 
debt issued by this VIE.

On  February  12,  2018, Ambac  formed  a VIE, Ambac  LSNI,  to 
issue  Secured  Notes  in  connection  with  the  Rehabilitation  Exit 
Transactions described further in Note 1. Background and Business 
Description.  Ambac does not consolidate the VIE since it does 
not have a variable interest in the trust.  Ambac reports its holdings 
of  Secured  Notes  within  Fixed  Income  Securities  in  the 
Consolidated  Balance  Sheets.  The  carrying  values  of  Secured 
Notes held by Ambac Assurance and Ambac as of December 31, 
2018  were  $584,622  and  $71,851,  respectively.   Ambac's    debt 
obligation to the VIE (the Ambac Note) had a carrying value of 
$1,940,289  and  is    reported  within  Long-Term  Debt  on  the 
Consolidated Balance Sheets.

NET INCOME PER SHARE 

As of December 31, 2018, 45,336,278 shares of Ambac's common 
stock (par value $0.01) and warrants entitling holders to acquire 
up to 4,877,783 shares of new common stock at an exercise price 
of $16.67 per share were outstanding.  For the three years ended 
December 31, 2018, 2017 and 2016, 194, 0 and 136 warrants were 
exercised, respectively, resulting in an issuance of 194, 0 and 136 
shares of common stock, respectively.

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 a $10,000 increase to 
the warrant repurchase program.  For the years ended December 
31, 2018 and 2017, Ambac did not repurchase any warrants.  As 
of December 31, 2018, Ambac had repurchased 985,331 warrants 
at a total cost of $8,092, (average cost of $8.21 per warrant).  The 
remaining  aggregate  authorization  at  December 31,  2018  was 
$11,939.  In connection with the AMPS Exchange, Ambac issued 
824,307 of the repurchased warrants at a price of  $9.72 per warrant 
on August 3, 2018.  Refer to Note 1. Background and Business

(1)  For the year ended December 31, 2017, Ambac has a net loss and 
accordingly  excluded  all  potentially  dilutive  securities  from  the 
determination  of  diluted  loss  per  share  as  their  impact  was  anti-
dilutive.

(2)  Performance stock units that are dilutive are reflected based on the 
performance metrics through the balance sheet date.  Performance 
stock units that are anti-dilutive are reflected at their target issuance 
amounts.  Vesting of these units is contingent upon meeting certain 
performance  metrics.    Although  a  portion  of  these  performance 
metrics  have  been  achieved  as  of  the  respective  period  end,  it  is 
possible that awards may no longer meet the metric at the end of the 
performance period.

FINANCIAL GUARANTEES IN FORCE 

Financial  guarantees  outstanding  includes  the  exposures  of 
policies that insure variable interest entities (“VIEs”) consolidated 
in  accordance  with  ASC  Topic  810,  Consolidation.  Financial 
guarantees outstanding includes the exposure of policies that insure 
capital appreciation bonds which are reported at the par amount at 
the  time  of  issuance  of  the  insurance  policy  as  opposed  to  the 
current  accreted  value  of  the  bonds.    Financial  guarantees 
outstanding exclude the exposures of policies that insure bonds 
which have been called, pre-refunded or refunded. The gross par 
amount of financial guarantees outstanding was $52,055,000 and 
$67,140,000 at December 31, 2018 and 2017, respectively. The 
par amount of financial guarantees outstanding, net of reinsurance, 
was $46,927,000 and $62,716,000 at December 31, 2018 and 2017,

(1)  Gross  premium  receivable  includes  premiums  to  be  received  in 
foreign denominated currencies most notably in British Pounds and 
Euros.  At  December 31, 2018, 2017 and 2016 premium receivables 
include British Pounds of $131,458 (£103,088), $151,852 (£112,342) 
and  $177,878  (£144,393),  respectively,  and  Euros  of  $30,597 
(€26,708),  $36,001 (€29,976) and $34,866 (€33,108), respectively. 

In structured finance transactions, the priority for the payment of 
financial  guarantee  premiums  to  Ambac,  as  required  by  bond 
indentures of insured structured finance obligations, is generally 
senior  in  the  waterfall.  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. Uncollectable premiums are 
determined on a policy basis and utilize a combination of historical 
premium  collection  data  in  addition  to  cash  flow  analysis  to 
determine  if  an  impairment  in  the  related  policy's  premium 
receivables exist.  At December 31, 2018 and 2017, $7,136 and 
$9,331  respectively,  of  premium  receivables  were  deemed 
uncollectable.  As of December 31, 2018 and 2017, approximately 
20%  and  22%,  respectively,  of  the  premium  receivables, net  of 
uncollectible  premiums,  related  to  transactions  with  non-
investment  grade  internal  ratings,  mainly  structured  finance 
transactions.  Past  due  premiums  on  policies  insuring  non-
investment  grade  obligations  amounted  to  less  than  $100  at 
December 31, 2018.

(1)  Future premiums to be collected are undiscounted and are used to 
derive the discounted premium receivable asset recorded on Ambac's 
balance sheet.  

(2)  Future  premiums  to  be  earned,  net  of  reinsurance  relate  to  the 
unearned  premiums  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 further described in Note 2. Basis of Presentation and 
Significant Accounting Policies.  This 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  may  result  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.

respectively, related to ceded reinsurance.

representations  and  warranties  within  losses  and  loss  expenses 
(benefit).  The losses and loss expense (benefit) incurred associated

$72,003 and $(71,369), respectively.

(3)  2018 loss and loss expenses (recovered) paid includes the settlement 
of Deferred Amounts and Interest Accrued on Deferred Amounts in 
the amount of $3,000,158 and $856,834, respectively in connection 
with the Rehabilitation Exit Transactions through a combination of 
cash, surplus notes and secured notes.  2018 loss and loss expenses 
incurred includes a $288,204 loss and loss expense benefit on these 
settled Deferred Amounts.

Additionally,  the  Balance  Sheet  line  "Reinsurance  recoverable  on

(5) 

Includes Euro denominated gross loss and loss expense reserves of 
$3,328  (€2,905),  $21,116  (€17,582)  and  $21,375  (€20,297)  at 
December 31, 2018, 2017 and 2016, respectively.

For 2018, the net positive development in prior years was primarily 
a  result  of  the  discount  recorded  on  the  Rehabilitation  Exit 
Transactions partially offset by negative development in the Public 
Finance portfolio and interest accrued on Deferred Amounts prior 
to the Rehabilitation Exit Transactions.

For 2017, the net adverse development in prior years was primarily 
the  result  of  negative  development  in  certain  public  finance 
transactions,  including  Puerto  Rico,  and  interest  accrued  on 
Deferred Amounts  partially  offset  by  positive  developments  in 
certain Ambac UK transactions, including a benefit of $144,600 
related to a confidential settlement of litigation brought by Ambac 
UK  in  the  name  of  Ballantyne  Re  plc  ("Ballantyne")  that  will 
reduce the ultimate Ballantyne claims Ambac UK is expecting to 
pay.

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 RMBS R&W subrogation 
recoveries 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.

Puerto Rico

its 

Ambac has exposure to the Commonwealth of Puerto Rico (the 
"Commonwealth")  and 
instrumentalities  across  several 
different  issuing  entities.  Each  has  its  own  credit  risk  profile 
attributable  to,  as  applicable,  discrete  revenue  sources,  direct 
general obligation pledges and/or general obligation guarantees. 
The  Commonwealth  of  Puerto  Rico  and  certain  of 
its 
instrumentalities have defaulted and may continue to default on 
debt service payments, including payments owed on bonds insured 
by Ambac Assurance. Ambac Assurance may be required to make 
significant amounts of policy claim payments over the next several 
years, the recoverability of which is subject to great uncertainty, 
which may lead to a material increase in permanent losses, causing 
a material adverse impact on our results of operations and financial 
condition. Our exposure to Puerto Rico is impacted by the amount 
of monies available for debt service, which is in turn affected by 

a  number  of  factors  including  demographic  trends,  economic 
growth, tax policy and revenues, impact of reforms, fiscal plans, 
government  actions,  budgetary  performance  and  flexibility, 
weather events, litigation outcomes, as well as federal funding of 
Commonwealth needs. In the near term, the financial and economic 
outlook  for  Puerto  Rico  is  dependent  upon  a  still  fragile 
infrastructure, heightening its vulnerability to additional weather 
events. The longer term recovery of the Commonwealth economy 
and its essential infrastructure will likely be dependent on, amongst 
other  factors,  the  management,  usage  and  efficacy  of  federal 
resources. 

Also  important  to  Puerto  Rico's  economic  growth,  government 
reform  and  creditor  outcomes  is  the  revised  fiscal  plan  for  the 
Commonwealth of Puerto Rico ("Revised Commonwealth Fiscal 
Plan"),  certified  by  the  Financial  Oversight  and  Management

(Dollar Amounts in Thousands, Except Share Amounts)

Board for Puerto Rico ("Oversight Board") on October 23, 2018. 
The  Revised  Commonwealth  Fiscal  Plan  outlines  a  series  of 
reforms, projects the fiscal and economic impact of those reforms, 
and  provides  forecasts  of  resulting  budgetary  surpluses  over  a 
fiscal  year  series.  However,  as  was  the  case  with  prior 
Commonwealth Fiscal Plans, the Revised Commonwealth Fiscal 
Plan lacks a high degree of transparency regarding the underlying 
data,  assumptions  and  rationales  supporting  those  assumptions, 
making reconciliation and due diligence difficult. As a result, it is 
difficult to predict the long-term capacity and willingness of the 
Puerto  Rico  government  and  its  instrumentalities  to  pay  debt 
service on bonded debt and how their debt burden and financial 
flexibility  might  affect Ambac Assurance's  claim  potential,  risk 
profile and long-term financial strength.

Substantial uncertainty exists with respect to the ultimate outcome 
for  creditors  in  Puerto  Rico,  such  as Ambac Assurance,  due  to, 
amongst other matters, legislation enacted by the Commonwealth 
and  the  federal  government,  including  PROMESA,  as  well  as 
actions  taken  pursuant  to  such  laws,  including  Title  III  filings.  
Ambac Assurance  is  involved  in  multiple  litigations  relating  to 
such actions and other issues and may not be successful in pursuing 
claims or protecting its interests.  As a result of litigation or other 
aspects of the restructuring processes, the difference among the 
credits insured by Ambac Assurance may not be respected.  

COFINA Debt Restructuring

On October 19, 2018, following the certification of the COFINA 
Fiscal  Plan,  the  Oversight  Board  filed  the  COFINA  Plan  of 
Adjustment  ("POA")  and  Disclosure  Statement  as  part  of  the 
COFINA Title III case.  The Oversight Board also filed a Rule 9019 
Motion  in  the  Commonwealth  Title  III  case  to  approve  the 
settlement of the Commonwealth-COFINA dispute. The filing of 
the  COFINA  POA  and  Disclosure  Statement  as  well  as  the 
settlement  motion  followed  the  execution  of  a  settlement 
agreement between the Oversight Board and the COFINA Agent. 
That settlement agreement is based on the previously announced 
agreement in principle developed by the COFINA Agent and the 
Commonwealth  Agent.  The  COFINA  POA  is  based  on  the 
settlement agreement as well as the preliminary agreement among 
COFINA  bondholders  announced  August  8,  2018  and  the 
subsequent  Plan  Support Agreement  and  term  sheet  among  the 
Oversight  Board,  FAFAA,  COFINA,  bond  insurers  (including 
Ambac  Assurance),  as  well  as  certain  COFINA  and  General 
Obligation creditors. 

The COFINA POA contemplated exchanging all existing COFINA 
senior and subordinate bonds for cash as well as new COFINA 
current  interest  and  capital  appreciation  bonds  ("new  COFINA 
bonds"). The  cash  and  new  COFINA  bonds  allocated  to  senior 
bondholders  equaled  approximately  93%  (considering  the  new 
COFINA bonds at par) of such senior bondholders’ allowed claim, 
in the amount of the COFINA senior bond accreted value, as of, 
but  not  including,  May  5,  2017  (the  COFINA Title  III  Petition 
Date). 

Pursuant to the COFINA POA, each holder of Ambac Assurance-
insured senior COFINA bonds had the option to elect by January 
11, 2019 to either (i) commute their rights in respect of the Ambac 
Assurance  insurance  policy  associated  with  the  existing  senior 
COFINA  bonds,  which  bonds  would  be  discharged  and Ambac 

Assurance  policy  obligations  with  respect  thereto  would  be 
released, in exchange for new COFINA bonds, cash amounts to be 
paid by COFINA, plus additional cash consideration provided by 
Ambac Assurance  equal  to  5.25%  of  the  accreted  value  of  the 
Ambac  Assurance-insured  senior  COFINA  bonds  as  of  the 
COFINA  Petition  Date  or  (ii)  agree  to  deposit  their  Ambac 
Assurance-insured senior COFINA bonds into a a trust in exchange 
for units issued by the trust (the "COFINA Class 2 Trust"), which 
trust would receive the new COFINA bonds and the cash amounts 
to be paid by COFINA that such bondholders would have otherwise 
received to the extent they had elected the recovery under clause 
(i) above (thereby entitling the COFINA Class 2 Trust to receive 
debt  service  payments  from  COFINA  with  respect  to  the  new 
COFINA  bonds  deposited  into  the  trust),  plus  any  accelerated 
policy  payments  (made  solely  at  Ambac  Assurance's  own 
discretion)  or  claim  payments  due  under  the  existing  Ambac 
Assurance  insurance  policy  for  the  deficiency  relating  to  the 
existing senior COFINA bonds at the relevant scheduled payment 
dates (2047 through 2054).  Any claims payable under the existing 
Ambac Assurance policy for the Ambac Assurance-insured senior 
COFINA bonds held in the trust will be reduced by all amounts 
distributed or deemed distributed from the trust to the holders of 
the trust units from the new COFINA bonds and cash as well as 
accelerated policy payments made by Ambac Assurance at its own 
discretion.  Ambac  makes  no  representation  and  can  give  no 
assurances that the new COFINA bonds or COFINA Class 2 Trust 
units,  both  of  which  are  not  insured  by Ambac Assurance,  will 
trade at par or any other price. Under the COFINA POA, Ambac 
Assurance-insured bondholders who did not affirmatively elect the 
trust option in clause (ii) above were deemed to have elected the 
commutation  option  described  in  clause  (i)  above.   As  of  the 
January  11,  2019  election  date,  74.9%  of  Ambac  Assurance-
insured senior COFINA bondholders, by measure of insured par, 
elected the commutation option or did not affirmatively elect to 
exchange their bonds for units of the COFINA Class 2 Trust.

On  February  4,  2019,  the  COFINA  Plan  of  Adjustment  was 
confirmed and the Commonwealth 9019 motion was approved by 
Judge Laura Taylor Swain of the U.S. District Court for the District 
of Puerto Rico. On February 12, 2019, the COFINA POA went 
effective,  concurrent  with  the  completion  of  the  commutation 
described  above.  Several  parties  are  presently  appealing  the 
confirmation of the POA and no assurances can be given regarding 
the results of such appeals. As a result, Ambac Assurance's insured 
COFINA  bond  exposure  decreased  significantly  and  Ambac 
Assurance's remaining policy obligation shall be an asset of the 
COFINA Class 2 Trust, which holds a ratable distribution of cash 
and  new  COFINA  bonds,  which  can  be  used  to  partially  offset 
Ambac’s remaining insurance liability.

At this time, it is unclear what impact the COFINA restructuring 
will have on the prospective recoveries of Ambac Assurance's other  
insured Puerto Rico instrumentalities.

While  our  reserving  scenarios  reflect  a  wide  range  of  possible 
outcomes, reflecting the significant uncertainty regarding future 
developments and outcomes, given our exposure to Puerto Rico 
and  the  economic,  fiscal,  legal  and  political  uncertainties 
associated therewith as well as the uncertainties emanating from 
the aftereffects of the damage caused by hurricanes Maria and Irma, 
our loss reserves may ultimately prove to be insufficient to cover

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. 

(2)  All  other  changes  which  may  impact  RMBS  R&W  subrogation 
recoveries  include  changes  in  actual  or  projected  collateral 
performance, changes in the creditworthiness of a sponsor and/or the 
projected timing of recoveries. All other changes may also include 
estimates of potential sponsor settlements that may not have been 
subject  to  a  sampling  approach  or  have  been  executed  but  the 
settlement amounts have not yet been received.  Those that have not 
been  subject  to  a  sampling  approach  are  not  material  to Ambac’s 
financial results and therefore are included in this table. 

Assumed Reinsurance: 

Assumed par outstanding was $219,100 and $219,100 at December 
31, 2018 and 2017, respectively. 

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 
$84,267  at  December 31,  2018.  Credit  exposure  existed  at 
December 31, 2018 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,  2018,  there  were  ceded  reinsurance  balances 
payable of $32,913 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 
(among  other  events  and 
downgrades  of  a 
circumstances).    Ambac  Assurance  held  letters  of  credit  and 
collateral  amounting 
its  reinsurers  at 
December 31,  2018.   As  of  December 31,  2018,  the  aggregate 
amount of insured par ceded by Ambac Assurance to reinsurers 
under  reinsurance  agreements  was  $5,128,000  with  the  largest 
reinsurer  accounting  for  $3,076,000  or  5.9%  of  gross  par 
outstanding at December 31, 2018.

our losses, potentially by a material amount, and may be subject 
to material volatility.

Ambac  has  considered  these  developments  and  other  factors  in 
evaluating its Puerto Rico loss reserves.  During the year ended 
December 31, 2018, Ambac had incurred losses associated with 
its Domestic Public Finance insured portfolio of $36,674, which 
was primarily impacted by the continued uncertainty and volatility 
of the situation in Puerto Rico, partially offset by an increase in 
loss  reserve  discount  rates.    While  management  believes  its 
reserves are adequate to cover losses in its Public Finance insured 
portfolio,  there  can  be  no  assurance  that Ambac  may  not  incur 
additional losses in the future, particularly given the developing 
economic, political, and legal circumstances in Puerto Rico.  Such 
additional losses may have a material adverse effect on Ambac’s 
results of operations and financial condition.   For public finance 
credits, including Puerto Rico, as well as other issuers, for which 
Ambac has an estimate of expected loss at December 31, 2018, the 
possible  increase  in  loss  reserves  under  stress  or  other  adverse 
conditions and circumstances was estimated to be approximately 
$1,000,000.  This possible increase in loss reserves under stress or 
other adverse conditions is significant and if we were to experience 
such 
losses,  our  stockholders’  equity  as  of 
December 31, 2018 would decrease from $1,633,147 to $633,147.

incremental 

However, there can be no assurance that losses may not exceed 
such amount. 

Representation and Warranty Recoveries:

Ambac records estimated RMBS R&W subrogation recoveries for 
breaches of R&W by sponsors of certain RMBS transactions.  For 
a  discussion  of  the  approach  utilized  to  estimate  RMBS  R&W 
subrogation  recoveries,  see  Note  2.  Basis  of  Presentation  and 
Significant Accounting Policies.  RMBS 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 below table.

Ambac has recorded RMBS R&W subrogation recoveries of 
$1,770,546, ($1,744,243 net of reinsurance) and $1,834,387, 
($1,806,736 net of reinsurance) at December 31, 2018 and 2017, 
respectively.

Insurance intangible asset:

The  insurance  intangible  amortization  expense  is  included  in 
insurance intangible amortization on the Consolidated Statements 
of  Total  Comprehensive  Income  (Loss).    For  the  years  ended 
December 31,  2018,  2017  and  2016,  the  insurance  intangible 
amortization  expense  was  $107,281,  $150,854  and  $174,608, 
respectively.    As  of  December  31,  2018  and  2017,  the  gross 
carrying value of the insurance intangible asset was $1,551,576 
and $1,581,156, respectively.  Accumulated amortization of the 
insurance  intangible  asset  was  $832,645  and  $734,183,  as  of 
December  31,  2018  and  2017,  respectively,  resulting  in  a  net 
insurance intangible asset of $718,931 and $846,973, respectively.

(1)   The insurance intangible asset will be amortized using a level yield 
method  based  on  par  exposure  of  the  related  financial  guarantee 
insurance or reinsurance contracts as described in Note 2. Basis of 
Presentation  and  Significant  Accounting  Policies.  Future 
amortization considers the use of contractual lives for many bond 
types which do not have homogeneous pools of underlying collateral. 
Actual  maturities  will  differ  from  contractual  maturities  because 
borrowers may have the right to call or prepay certain obligations. If 
those bonds types are retired early, amortization expense may differ 
in the period of call or refinancing from the amounts provided in the 
table above.

INSURANCE REGULATORY RESTRICTIONS 

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. 

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. 

As the principal, or domiciliary, regulator of Ambac Assurance and 
Everspan, OCI has primary regulatory authority, including with 
respect  to  the  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 
their  capital  structure, 
ownership,  financial  condition  and  enterprise  risk.  Ambac 
Assurance  and  Everspan  are  not  subject  to  risk-based  capital 
requirements, since they are financial guarantee insurers. Ambac 
Assurance 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. 

information  concerning 

In addition, pursuant to the terms of the Settlement Agreement, the 
Stipulation and Order and the indenture for the Tier 2 Notes, Ambac 
Assurance must seek prior approval by OCI of certain corporate 
actions.  The  Settlement Agreement,  Stipulation  and  Order  and 
indenture for the Tier 2 Notes include covenants which restrict the 
operations of Ambac Assurance. The Settlement Agreement will 
remain in force until the surplus notes that were issued  pursuant 
to the Settlement Agreement have been redeemed, repurchased or 
repaid in full. The Stipulation and Order will remain in force for 
so long as OCI determines it to be necessary. The indenture for the 
Tier 2 Notes will remain in force until the Tier 2 Notes have been 
redeemed, repurchased or repaid in full. Certain of the restrictions 
in the Settlement Agreement and the indenture for the Tier 2 Notes

may be waived with the approval of the OCI and/or the requisite 
percentage of holders of the related debt securities. 

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, 2018, 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 for 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  $1,152,346  at 
December 31, 2018, as compared to $699,614 as of December 31, 
2017. 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, 2018 and 2017 was lower by $41,814 and lower by 
$104,097, respectively, than if Ambac Assurance had reported such 
amounts in accordance with NAIC SAP. 

Prescribed Accounting Practices:

OCI has prescribed the following accounting practice that differ 
from NAIC SAP for Ambac Assurance:  

•  Paragraph 8 of Statement of Statutory Accounting Principles 
No. 60 “Financial Guaranty Insurance” 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 Assurance 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, 2018 and 2017 were 5.87% and 9.52%, 
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. 

•  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  statutory  accounting  principles, 
surplus notes issued in conjunction with commutations or the 
settlement  of  obligations  would  be  valued  at  zero  upon 
issuance pursuant to paragraph 4, SSAP 41.  OCI has directed 
the  Company  to  record  surplus  notes  issued  in  connection 
with commutations or the settlement of obligations at full par 
value upon issuance.  The surplus notes issued have a claim 
against  surplus  senior  to  the  preferred  and  common 
shareholders.

•  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  ("OTTI") 
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.  
Beginning  June  11,  2014,  as  a  result  of  the  amended 
Segregated Account Rehabilitation Plan, OCI has directed the 
Company to not evaluate investments in Ambac Assurance 
insured  securities  with  policies  that  were  allocated  to  the 
Segregated  Account  for  OTTI  and  require  all  such 
investments be reported at amortized cost regardless of its 
NAIC risk designation. This accounting determination was 
intended  to  recognize  that Ambac Assurance  continues  to 
maintain statutory loss reserves 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.  
Effective February 12, 2018, with the Segregated Account's 
exit from Rehabilitation, this prescribed practice is no longer 
applicable for OTTI evaluations going forward. 

•  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 in Ambac Assurance’s statutory basis 
financial statements.  Pursuant to this prescribed practice, the 
results of the Segregated Account were not included in Ambac 
Assurance’s  financial  statements  if  Ambac  Assurance’s 

| Ambac Financial Group, Inc.   104   2018 FORM 10-K |

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

surplus is (or would be) less than $100,000 (the “Minimum 
Surplus Amount”).   As  long  as  the  surplus  as  regards  to 
policyholders  was  not  less  than  the  Minimum  Surplus 
Amount, payments by Ambac Assurance to the Segregated 
Account  under  agreements  between  the  parties  are  not 
capped.  Effective  February  12,  2018  with  the  Segregated 
Account's exit from rehabilitation, this prescribed practice is 
no longer applicable.  

Permitted Accounting Practices:

OCI has allowed the following permitted practices that differ from 
NAIC SAP for Ambac Assurance: 

•  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, in accordance with NAIC SAP. 

•  Ambac Assurance received permission from OCI to report 
investment holdings of Ambac Assurance insured securities 
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. 

•  Effective  upon  the  exit  of  the  Segregated  Account  from 
rehabilitation and the merger of the Segregated Account with 
and  into  Ambac  Assurance,  Ambac  Assurance  received 
permission from OCI to restate its unassigned funds (surplus) 
balance to $100,000 with an offsetting reduction to gross paid-
in  and  contributed  surplus  such  that  total  surplus  remains 
unchanged. 

•  In  connection  with  the AMPS  Exchange  in  2018, Ambac 
Assurance  received  permission  from  OCI  of  a  permitted 
practice  to  account  for  the  exchange  of  AMPS  for  5.1% 
surplus notes in a manner that ensures compliance with certain 
state insurance regulations that require a minimum surplus 
level. Accordingly, Ambac Assurance recorded the excess of 
the  consideration  paid  over  the  par  value  of  the AMPS  as 
follows: i) first as a reduction to gross paid-in and contributed 
surplus up to an amount that resulted in a gross paid-in and 
contributed surplus balance of not less than $75,000 and ii) 
for  any  remaining  excess,  as  a  reduction  to  unassigned 
surplus.   This  permitted  practice  only  impacts  the  balance 
sheet classification and has no impact on statutory surplus.

United Kingdom 

The  Prudential  Regulatory  Authority  (“PRA”)  and  Financial 
Conduct Authority (“FCA”) (and their predecessor regulator the 
Financial  Services  Authority  (“FSA”))  are  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. 

These regulators 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  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 2019 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 indenture for the Tier 2 
Notes (as described below), by the terms of its AMPS (as described 
below) and by the Stipulation and Order. 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, 

| Ambac Financial Group, Inc.   105   2018 FORM 10-K |

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

minus realized capital gains for those calendar years and minus 
dividends paid or credited within the first two of the three preceding 
calendar years.  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 

9. 

FAIR VALUE MEASUREMENTS 

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  Ambac  Assurance's 
surplus notes would also need to be redeemed at par.  The indenture 
for  the Tier  2  Notes  contains  a  similar  restrictive  covenant  and 
further  requires  a  proportional  payment  of  the Tier  2  Notes  (or 
interest thereon) when payments are made on the surplus notes.

Under the terms of Ambac Assurance’s 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.

The Stipulation and Order requires OCI approval for the payment 
of any dividend or distribution on the common stock of Ambac 
Assurance.

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

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.

Level 2

Level 3

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  investments  in  fixed  income  securities  representing 
municipal, asset-backed and corporate obligations, certain interest rate swap contracts and most long-term debt of financial 
guarantee variable interest entities consolidated under the Consolidation Topic of the ASC. 

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, certain uncollateralized 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 include fixed income securities, 
loan receivables, and certain long-term debt of financial guarantee variable interest entities consolidated under the Consolidation 
Topic of the ASC.

(Dollar Amounts in Thousands, Except Share Amounts)

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.   The  determination  of  fair  value  for 
financial instruments categorized in Level 2 or 3 involves 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 values for 
financial instruments.  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  mainly 
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 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. 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 calculate fair value.  
Such prices generally consider a variety of factors, including recent 
trades of the same and similar securities.  In those cases, the items 
are classified within Level 2. 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.  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.    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.    At 
December 31,  2018,  approximately  8%,  90%,  and  2%  of  the 
investment  portfolio 
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,  2017, 
approximately 6%, 79%, and 15% of the fixed income 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. 

(excluding  variable 

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:    A  portion  of  these 
securities were guaranteed under policies that were subject to the 
Segregated Account Rehabilitation Plan and had projected future 
cash  flows  consisting  solely  of  Deferred Amounts  under  such 
policies  including  interest  thereon.    As  described  in  Note  1. 
Background and Business Description, upon consummation of the 
Rehabilitation  Exit  Transactions  on  February  12,  2018,  all 
Deferred  Amounts  have  been  settled.    The  fair  value  of  such 
securities classified as Level 3 was $0 and $709,950 at December 
31, 2018 and 2017, respectively.  Fair value was calculated based 
on the valuation of Ambac Assurance surplus notes which, under 
the terms of the Segregated Account Rehabilitation Plan effective 
in 2017, were to be redeemed in proportion with the payment of 
Deferred Amounts on or about the dates when such payments are 
made.  

The  remaining  portion  of  Level  3  residential  mortgage-backed 
securities  as  of  December 31,  2017  was  an Ambac-insured  re-
REMIC  containing  distressed  mortgage-backed  securities  as 
collateral.  The security was transfered from Level 3 to Level 2

during 2018.  The fair value of this security was $26,067 as of 
December 31, 2017.  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, 2018 were as 
follows:

December 31, 2017:
a.  Coupon rate.............................................. 2.05%
b.  Average Life ............................................ 0.65 years
c.  Yield......................................................... 10.00%

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 $72,071 and $72,540 at December 31, 2018 and 
2017, 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, 2018 and 2017 
include the following weighted averages:

December 31, 2018:

a.  Coupon rate.............................................. 5.97%

b.  Average Life ............................................ 16.29 years

c.  Yield......................................................... 12.00%

December 31, 2017:

a.  Coupon rate.............................................. 5.97%

b.  Average Life ............................................ 17.02 years

c.  Yield......................................................... 12.00%

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.    Refer  to  Note  10.  Investments  for    additional 
information  about  such  investments  in  pooled  funds  that  are 
reported at fair value  using NAV as a practical expedient.

Other investments also includes Ambac's equity 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 
swaps, credit default swaps and exchange traded futures contracts. 
Fair  value  is  determined  based  upon  market  quotes  from 
independent sources, when available. 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 derivatives and other liabilities.  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 derivative 
and the pricing of recent terminations.  The fair value of credit 
derivative liabilities was reduced by $138 and $60 at December 
31, 2018 and 2017, respectively, as a result of incorporating an 
Ambac CVA into the valuation model for these contracts. Interest 
rate swap liabilities are collateralized and are not adjusted with an  
Ambac CVA at December 31, 2018 and 2017.  

Interest rate swaps that are not centrally cleared are valued using 
vendor-developed models that incorporate interest rates and yield 
curves that are observable and regularly quoted.  These models 
provide the net present value of the derivatives based on contractual 
terms  and  observable  market  data.  Generally,  the  need  for 
counterparty  (or  Ambac)  CVAs  on  interest  rate  derivatives  is 
mitigated by the existence of collateral posting agreements under 
which  adequate  collateral  has  been  posted.  Certain  of  these 
derivative  contracts  entered  into  with  financial  guarantee 
customers  are  not  subject  to  collateral  posting  agreements. 
Counterparty credit risk related to such customer derivative assets 
is included in our fair value adjustments. 

Ambac's remaining credit derivatives ("CDS") are valued using an 
internal  model  that  uses  traditional  financial  guarantee  CDS 
pricing to calculate the fair value of the derivative contract  based 
on the reference obligation's current pricing, remaining life and  
credit rating and Ambac's own credit risk.   The model calculates 
the  difference  between  the  present  value  of  the  projected  fees 
receivable under the CDS and our estimate of the fees a financial 
guarantor of comparable credit quality would charge to provide 
the same protection at the balance sheet date.   Unobservable inputs 
used include Ambac's internal reference obligation credit ratings 
and expected life, estimates of fees that would be charged to assume 
the credit derivative obligation and Ambac's CVA. Ambac is party 
to only two remaining credit derivatives with internal credit ratings 
of AA or better at December 31, 2018. Ambac has not made any 
significant changes to its modeling techniques or related model 
inputs for the periods presented.

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 

| Ambac Financial Group, Inc.   110   2018 FORM 10-K |

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

assumed contracts, net cash flows for each policy includes future: 
(i) installment  premium  receipts,  (ii) 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 was at 
the  sole  discretion  of  the  Rehabilitator  until  the  Segregated 
Account rehabilitation was concluded on February 12, 2018.  For 
ceded reinsurance contracts, net cash flows for each policy includes 
future:  (i) installment  ceded  premium  payments,  (ii) ceding 
commission  receipts,  (iii) ceded  claim  receipts,  and  (iv) ceded 
subrogation  payments.  For  each  assumed  or  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.  A profit margin was developed based 
on  discussions  with  the  third-party  institutions  with  valuation 
expertise and discussions with industry participants.  The discount 
rates used for contracts in a net liability position are derived from 
the rates implicit in the fair value of guaranteed securities with 
future cash flows that are highly dependent upon Ambac financial 
guarantee payments.  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,  since  no  financial 
guarantor  with Ambac Assurance’s  credit  quality  is  writing  or 
otherwise obtaining financial guarantee business (e.g. reinsurance 
or novation of policies from other insurers) we do not have access 
to observable pricing data points.

Long-term Debt:

Long-term debt includes Ambac Assurance senior surplus notes 
and junior surplus notes,  notes outstanding to third parties arising 
from  Ambac  Assurance's  Secured  Borrowing 
transaction 
(redeemed in June 2018) and the Ambac Note and Tier 2 Notes 
issued in connection with the Rehabilitation Exit Transactions.  The 
fair values of senior surplus notes, the Secured Borrowing notes, 
the Ambac Note and Tier 2 Notes are classified as Level 2.  The 
fair value of junior surplus notes are classified as Level 3.

Other Financial Assets and Liabilities:

The fair values of Loans and Ambac’s equity interest in Ambac 
sponsored VIEs (included in Other assets) are estimated based 
upon internal valuation models and are classified as Level 3.

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 
notes secured primarily by 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 $217,092 and $2,757,688 at December 
31, 2018 and 2017, 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, 2018 and 2017
include the following weighted averages:

December 31, 2018

a.  Coupon rate.............................................. 2.20%

b.  Maturity ................................................... 18.93 years

c.  Yield......................................................... 3.18%

December 31, 2017

a.  Coupon rate.............................................. 0.40%

b.  Maturity ................................................... 15.28 years

c.  Yield......................................................... 4.82%

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,  2018  and  2017  were  developed  using  vendor-
developed models and do not use significant unobservable inputs.

The fair value of VIE assets are obtained from market quotes when 
available. Typically VIE 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  derived  from  the  fair  value  of  notes  and

(Dollar Amounts in Thousands, Except Share Amounts)

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 3.1% and 
3.1% at December 31, 2018 and 2017, 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 for Financial Assets and Liabilities Accounted for at Fair Value:

The following tables present the changes in the Level 3 fair value category for the periods presented in 2018, 2017 and 2016. 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.  Non-agency RMBS securities transferred 
from Level 2 into Level 3 in 2017, and out of Level 3 into Level 
2 in 2018, include an Ambac-insured re-REMIC collateralized by 
distressed  mortgage-backed  securities.    Non-agency  RMBS 
transferred  into  Level  3  in  2017  and  2016  consist  of  certain 
investments  in  Ambac-wrapped  RMBS  securities  for  which 
projected  cash  flows  consist  solely  of  Deferred  Amounts  and 
interest  thereon.    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. 
  These  invested  assets  were  internally  valued  as 
management either could not obtain or 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.   There were no transfers of derivative instruments into 
or out of Level 3 in the periods disclosed.

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, 
2018 and 2017 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 outflow 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, the fair value of other securities that 
are available for sale and in an unrealized gain position, trading 
securities plus the scheduled maturities 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.    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, 2018, 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, 2018, $660,063 of the total fair value and $17,838
of the unrealized loss related to below investment grade and non-
rated securities. Of the securities that were in a gross unrealized 
loss position at December 31, 2017, $1,855,694 of the total fair 
value  and  $100,503  of  the  unrealized  loss  related  to  below 
investment grade and non-rated securities.  As discussed further 
below, most of the securities in a gross unrealized loss position 
that are below investment grade or non-rated are guaranteed by 
Ambac Assurance.   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.  If that judgment changes, Ambac may 
ultimately record a charge for other-than-temporary impairment in 
future periods.

Municipal obligations

The  gross  unrealized  losses  on  municipal  obligations  as  of 
December 31, 2018 are primarily on Puerto Rico bonds that are 
guaranteed by Ambac Assurance.  Management assessed whether 
these  securities  suffered  credit  impairment  as  of  December  31, 
2018  based  on  the  value  of  cash  and  securities  received  in  the 
February 2019 commutation transactions executed in connection 
with  the  COFINA  Plan  of  Adjustment.    Management  has 
determined that the amortized cost bases of these securities are 
fully recoverable. 

Corporate obligations

The  gross  unrealized  losses  on  corporate  obligations  as  of 
December 31,  2018  are  primarily  the  result  of  the  increase  in 
interest rates since purchase. 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.

Realized Gains and Losses and Other-Than-Temporary 
Impairments:

Counterparty Collateral, Deposits with Regulators and 
Other Restrictions:

Ambac routinely pledges and receives collateral related to certain 
transactions.  Cash, cash equivalents and securities held directly 
in Ambac’s  investment  portfolio  with  a  combined  fair  value  of 
$102,904  and  $120,645  at  December  31,  2018  and  2017, 
respectively, were pledged to derivative counterparties.  Ambac’s 
derivative counterparties have the right to re-pledge the investment 
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”.  There was no cash 
or  securities  received  from  other  counterparties  that  were  re-
pledged by Ambac.

Securities carried at $5,975 and $5,974 at December 31, 2018 and 
2017,  respectively,  were  deposited  by  Ambac  Assurance  and 
Everspan with governmental authorities or designated custodian 
banks as required by laws affecting insurance companies.

Securities with fair value of $0 and $346,212 at December 31, 2018 
and 2017, respectively, were held by a bankruptcy remote trust to 
collateralize  and  fund  repayment  of  debt  issued  through  a 
securitization  transaction.  The  securities  may  not  be  sold  or 
repledged by the trust. These assets were held and the secured debt 
was issued by entities that qualified as VIEs and are consolidated 
in Ambac’s  consolidated  financial  statements.  Refer  to  Note  3. 
Variable  Interest  Entities  for  a  further  description  of  this 
transaction.

As  further  discussed  in  Note  1.  Background  and  Business 
Description, Ambac LSNI, an unconsolidated VIE, issued Secured 
Notes in connection with the Rehabilitation Exit Transactions of 
February  12,  2018.  Securities  with  a  fair  value  of  $209,983  at 
December 31, 2018 were pledged as collateral and as sources of 
funding  to  repay  the  Secured  Notes. The  securities  may  not  be 
transferred or repledged by Ambac LSNI. Collateral may be sold 
to fund redemptions of the Secured Notes. Ambac Assurance also 
pledged for the benefit of the holders of Secured Notes (other than 
Ambac Assurance)  the  proceeds  of  the  Secured  Notes  held  by 
Ambac  Assurance.    The  amount  of  such  proceeds  from  the 
December  31,  2018  interest  payment  and  partial  redemption  of 
Secured  Notes  held  by Ambac Assurance  was  $19,405  and  is 
included in Restricted cash on the Consolidated Balance Sheet at 
December 31, 2018.

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.

During  the  Segregated  Account  Rehabilitation  Proceedings, 
changes  in  the  estimated  timing  of  claim  payments  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  years  ended  December  31, 
2017 and 2016 presented in the table above.  

Future changes in our estimated liquidity needs could result in a 
determination  that  Ambac  no  longer  has  the  ability  to  hold 
securities that are in an unrealized loss position, which could result 
in additional other-than-temporary impairment charges.

The following table presents a roll-forward of Ambac’s cumulative 
credit losses on debt securities held as of December 31, 2018 and 
2017 for which a portion of an other-than-temporary impairment

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). 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, 2018 and 2017, respectively:

(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. Ambac sold its position in this 
fund in 2018.

(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 term, resulting in expected capital distributions 
to subscribers between 2020 and 2023.  Redemptions were not able to occur prior to the expiration of the investment lock-up period in May 2018.

(5)  This class aims to provide returns from the insurance and reinsurance markets through investments in catastrophe bonds, life insurance and other insurance 
linked investments.  Redemption periods are quarterly, subject to 90-day notice for January/July redemption dates and 120-day notice for April/October 
redemption dates with redemptions greater than 3.5% during the first five years following share issuance subject to redemption fees.

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.  Credit derivatives 
issued are insured by Ambac Assurance. None of the outstanding 
credit derivative transactions at December 31, 2018 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 a financial guarantee 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  summarizes  the  gross 
principal notional outstanding for CDS contracts, by Ambac rating 
as of December 31, 2018 and 2017:

(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.

Interest Rate Derivatives:

Ambac, through its subsidiary Ambac Financial Services (“AFS”), 
uses  interest  rate  swaps  and  US  Treasury  futures  contracts  to 
provide an economic hedge against the effects of rising interest 
rates elsewhere in the Company, including on Ambac’s financial 
guarantee  exposures.     Additionally, AFS  provided  interest  rate 
swaps to states, municipalities and their authorities, asset-backed 
issuers and other entities in connection with their financings.  As 
of  December  31,  2018  and  2017  the  notional  amounts  of  its 
derivatives are as follows:

On June 27, 2017, Ambac entered into a termination agreement 
with various parties in connection with the commutation of interest 
rate swaps between an asset-backed issuer and AFS.  Ambac paid 
$94,407 under the termination agreement and reported a gain on 
the  terminated  swaps  of  $43,443  within  net  gains  (losses)  on 
derivative  contracts  on  the  Consolidated  Statements  of  Total 
Comprehensive Income (Loss).  

Derivatives of Consolidated Variable Interest Entities

Certain VIEs consolidated under the Consolidation Topic of the 
ASC entered into derivative contracts to meet specified purposes 
within  their  securitization  structure.  The  notional  for  VIE

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  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, 2018 and 2017, the net liability fair value of 
derivative instruments with contingent features linked to Ambac’s 
own credit risk was $67,071 and $79,912, respectively, related to 
which Ambac had posted cash, cash equivalents and securities as 
collateral with a fair value of $92,657 and $111,391, 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 such contracts terminated on December 31, 2018, 
settlement of collateral balances and net derivative liabilities would 
result  in  a  net  receipt  of  cash  and/or  securities  by  Ambac.  If 

| Ambac Financial Group, Inc.   123   2018 FORM 10-K |

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

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  market  values  as  reported  in  Ambac’s  financial 
statements.

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 extended by consolidated VIEs are generally carried at fair 
value on the Consolidated Balance Sheets. See Note 3. 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 $19,191 and 
$20,184  at  December  31,  2018  and  2017,  respectively.    The 
effective interest rate on these loans ranged from 6.51% to 8.60% 
and 6.51% to 8.07% at December 31, 2018 and 2017, respectively. 
The  maturity  date  of  these  loans  ranged  from  June  2026  to 
December 2046 as of December 31, 2018.  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, 2018 and 2017.

Surplus Notes

Ambac Assurance surplus notes, with a par amount of $530,744 
and $754,811 at December 31, 2018 and 2017, respectively have 
a scheduled maturity of June 7, 2020. On February 12, 2018, the 
Rehabilitation Exit Transactions were consummated, resulting in 
a  $463,624  reduction  of  consolidated  surplus  notes  par 
outstanding.  On August  3,  2018,  in  connection  with  the AMPS 
Exchange,  Ambac  Assurance  issued  surplus  notes  with  a  par 
amount of $212,740.  Also, during the year ended December 31, 
2018, sales of surplus notes held by Ambac and other transactions 
resulted in additional net issuance of $26,817 Ambac Assurance 
surplus note par value. In 2017, Ambac purchased $147,236 par 
amount of these surplus notes. The retirement of certain notes as 
part of the Rehabilitation Exit Transactions in 2018 and Ambac 
purchases in 2017 resulted in gains of $3,121 and $3,815 for the 

years  ended  December  31,  2018  and  2017,  respectively,  
recognized in Net realized gains (losses) on extinguishment of debt 
on the Consolidated Statements of Total Comprehensive Income.  

Surplus notes outstanding are recorded at their fair value at the 
date of issuance. The discount on surplus notes is accreted into 
income using the effective interest method based on projected cash 
flows  at  the  date  of  issuance.  The  weighted  average  imputed  
interest rate on surplus notes outstanding as of December 31, 2018
is 10.1%. All payments of principal and interest on these surplus 
notes are subject to the prior approval of the OCI. Annually from 
2011 through 2018, OCI issued its disapproval of the requests of 
Ambac Assurance to pay the full interest on outstanding surplus 
notes on the annual scheduled interest payment date of June 7th. 
If the OCI does not approve the payment of interest on these surplus 
notes, such interest will accrue and compound annually until paid. 
In connection with the Rehabilitation Exit Transactions, Ambac 
Assurance made a one-time current interest payment on remaining 
surplus notes (other than junior surplus notes) of $13,501, of which 
$2,618 was received by Ambac for surplus notes that it owned and 
that are considered extinguished for accounting purposes.

Refer to Note 1. Background and Business Description for further 
discussion  of  both  the  Rehabilitation  Exit Transactions  and  the 
AMPS Exchange.

Junior Surplus Notes

The junior surplus notes have a par value of $366,644 and $370,237
at  December  31,  2018  and  2017,  respectively.  Pursuant  to  the 
Second  Amended  Plan  of  Rehabilitation,  Ambac  Assurance 
became the obligor under the junior surplus notes (originally issued 
by the Segregated Account) as of February 12, 2018.  These junior 
surplus notes 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 surplus notes (other than junior surplus notes) are paid 
in full and after all of Ambac Assurance's future and existing senior 
indebtedness, policy and other priority claims have been paid in 
full. All payments of principal and interest on these 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, 2018 and 2017 includes $16,644
and $20,237, 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 ($1,661 current par 
value at December 31, 2018) are reducing periodically as rent 
payments under the replacement lease (beginning in January 
2016) are made by Ambac Assurance. Par value of these junior 
surplus notes was reduced by $3,593 and $3,799 during the 
year ended December 31, 2018 and 2017, respectively, as rent 
payments  were  made  by  Ambac  Assurance.  These  junior 
surplus notes were recorded at their fair value at the date 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, 2018 and 2017 includes $350,000 
face  amount  of  a  junior  surplus  note  originally  issued  to 
Ambac pursuant to Ambac's Chapter 11 Reorganization Plan 
in  accordance  with 
the  Mediation  Agreement  dated 
September 21, 2011 among Ambac, Ambac Assurance, the 
Segregated  Account,  the  Rehabilitator,  the  OCI  and  the 
Official Committee of Unsecured Creditors of Ambac, 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%. 

Ambac Note

The Ambac Note, issued in connection with the Rehabilitation Exit 
Transactions on February 12, 2018, as more fully described in Note 
1.  Background  and  Business  Description,  has  a  par  value  of 
$1,940,289  at  December 31,  2018,  and  has  a  legal  maturity  of 
February 12, 2023.  Interest on the Ambac Note is payable quarterly 
(on the last day of each quarter beginning with June 30, 2018) at 
an annual rate of 3-month U.S. Dollar LIBOR + 5.00%, subject to 
a 1.00% LIBOR floor. During the year ended December 31, 2018, 
$214,062  par  value  of  the  Ambac  Note  was  redeemed.    The 
maturity date for the Ambac Note is the earlier of (x) February 12, 
2023, and (y) if the Secured Notes are then outstanding, the date 
that  is  five  business  days  prior  to  the  date  for  which  OCI  has 
approved the repayment of the outstanding principal amount of the 
surplus notes (other than junior surplus notes) issued by Ambac 
Assurance. Promptly, and in any event within four business days 
after  the  receipt  (whether  directly  or  indirectly)  of  any 
representation  and  warranty  subrogation  recoveries,  Ambac 
Assurance shall (i) apply an amount (the “Mandatory Redemption 
Amount”)  equal  to  the  lesser  of  (a)  the  amount  of  such 
representation  and  warranty  subrogation  recoveries  and  (b)  all 
outstanding  principal  and  accrued  and  unpaid  interest  on  the 
Ambac Note to redeem the Ambac Note, in whole or in part, as 
applicable;  provided,  that  any  non-cash    representation  and 
warranty subrogation recoveries shall be deemed to be received 
upon the receipt of the applicable appraisal.   

The  portion  of  the Ambac  Note  issued  in  connection  with  the 
exchange of surplus notes ("Ambac Note A") was accounted for 
as  a  debt  modification  since  the  creditors  before  and  after  the 
exchange  remained  the  same  and  the  change  in  terms  was  not 
considered substantial. A substantial change is considered to be a 
change in cash flows of equal to or greater than 10%, and because 
the change in cash flows was less than 10%, debt modification 
accounting  is  appropriate.  Under  debt  modification  accounting, 
Ambac  Note A  was  recorded  at  a  discount  to  par  based  on  the 
carrying value of the surplus notes less the cash consideration paid.  
Furthermore,  no  gain  or  loss  was  recorded  on  the  surplus  note 
exchange and a new effective interest rate was established based 
on  the  cash  flows  of  Ambac  Note  A.  Any  consideration  paid 
directly related to the issuance of Ambac Note A was expensed as 
incurred.  The portion of the Ambac Note issued in connection with 
the  exchange  of  Deferred  Amounts  ("Ambac  Note  B")  was 
recorded  at  fair  value.  The  Deferred  Amount  exchange  was 
accounted for as an extinguishment of the Deferred Amounts with 

the  gain  reflected  as  a  benefit  to  loss  and  loss  expenses. Any 
consideration paid directly related to the issuance of Ambac Note 
B  was  capitalized  and  amortized  as  part  of  the  effective  yield 
calculation.  The  aggregate  discount  on  the  entire Ambac  Note 
(portions A  and  B)  was  accreted  into  earnings  from  the  date  of 
issuance through September 30, 2018 using the effective interest 
method,  based  on  an  imputed  interest  rate  of  7.6%.    As  of 
December 31, 2018 the discount on the Ambac Note has been fully 
amortized.

Tier 2 Notes

The Tier 2 Notes, issued in connection with the Rehabilitation Exit 
Transactions on February 12, 2018, with a par value of $258,585
(including paid-in-kind interest of $18,585) at December 31, 2018
have a legal maturity of February 12, 2055. Interest on the Tier 2 
Notes is at an annual rate of 8.50%.  Other than upon payment of 
principal at redemption or maturity, interest payments will not be 
made in cash on interest payment dates and shall be paid-in-kind 
and compounded on the last day of each calendar quarter.  The Tier 
2 Notes were recorded at a discount to par as any consideration 
paid that was directly related to the issuance of the Tier 2 Notes 
was capitalized and is part of the effective yield calculation. Ambac 
is accreting the discount on the Tier 2 Notes into earnings using 
the effective interest method, based on an imputed interest rate of 
9.9%.

The Tier  2  Notes  are  subject  to  mandatory  redemption  triggers 
upon: (i) receipt of subject representation and warranty subrogation 
recoveries in excess of $1,600,000 ("Tier 2 Net Proceeds") or (ii) 
payment of principal or interest on Ambac Assurance surplus notes 
(other than junior surplus notes).  Promptly, and in any event within 
five business days after the receipt (whether directly or indirectly) 
of Tier 2 Net Proceeds, Ambac Assurance shall  deposit an amount 
equal to the Tier 2 Net Proceeds to a collateral account, provided, 
that  any  non-cash    representation  and  warranty  subrogation 
recoveries shall be deemed to be received upon the receipt of the 
applicable appraisal.  Similarly, within five business dates after a 
surplus  note  payment  (other  than  in  connection  with  the 
Rehabilitation Exit Transactions), Ambac Assurance shall deposit 
an amount based on the percentage of surplus notes paid applied 
to  the  outstanding  balance  of  the  Tier  2  Notes  to  a  collateral 
account.  In both cases, the amount deposited shall not be in excess 
of  the  amount  required  to  redeem  all  outstanding Tier  2  Notes.  
Also, such amounts shall be used to initiate a redemption.  

The Tier 2 Notes may also be redeemed, in whole or in part, at the 
option  of  Ambac  Assurance.    Both  mandatory  and  optional 
redemptions may be made at a price equal to 100% of the aggregate 
principal amount redeemed, plus accrued and unpaid interest, if 
any,  plus  a  make-whole  premium.  Make-whole  premiums  are 
calculated  based  on  future  interest  payments  through  the 
contractual call date ("Initial Call Date"). The Initial Call Date at 
issuance of December 17, 2020 extends ratably beginning the first 
anniversary  of  issuance  to  September  17,  2021  by  the  second 
anniversary, and to March 17, 2022 by the third anniversary of 
issuance.  There are no extensions of the Initial Call Date beyond 
March  17,  2022.    The  Initial  Call  Date  for  redemptions  is 
determined based on the date the applicable amounts are deposited 
to the collateral account.

In connection with our preliminary analysis of the TCJA, during 
2017 Ambac  recorded  an  estimated  discrete  current  benefit  of 
$29,581  related  to  the  repeal  of  the Alternative  Minimum  Tax 
("AMT")  and  a  deferred  tax  expense  of  $31,418  attributable  to 
Ambac UK, resulting in an estimated net cost of $1,886. 

Ambac  completed  its  accounting  of  the  TCJA  during  2018, 
including  the  mandatory  repatriation  of Ambac  UK's  historical 
earnings and the limitations on executive compensation, which had 
previously been disclosed as estimates.  A discrete benefit for the 
TCJA of $1,902 was recorded during 2018 related to the repeal of 
AMT.  Upon the filing of its 2018 through 2021 federal income

Secured Borrowing

The  secured  borrowing,  with  a  par  value  of  $0  and  $73,993  at 
December 31, 2018 and 2017, respectively had a legal maturity of 
July  25,  2047.    Interest  on  the  secured  borrowing  was  payable 
monthly at an annual rate of one month LIBOR + 2.8%. On June 
22, 2018, the Secured  Borrowing was fully redeemed. Refer to 
Note  3.  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 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  $4,552,643  and 
$9,387,884 as of December 31, 2018 and 2017, respectively. As 
of December 31, 2018 and 2017, the ranges of final maturity dates 
of the outstanding long-term debt associated with these VIEs were 
September 2019 to December 2047 as of December 31, 2018, and 
November 2018 to December 2047 as of December 31, 2017.  As 
of December 31, 2018 and 2017, the interest rates on these VIEs’ 
long-term debt ranged from 1.36% to 7.93% and from 0.96% to

INCOME TAXES 

Ambac files a consolidated U.S. Federal income tax return with 
its subsidiaries. Ambac and its subsidiaries also file separate or 
combined income tax returns in various states, local and foreign

On December 22, 2017, H.R. 1. (commonly referred to as the Tax 
Cut  and  Jobs  Act  or  "TCJA")  was  enacted  and  significantly 
changed  the  tax  code  effective  January  1,  2018.  Given  the 
complexity of the TCJA and the limited time between its enactment 
and  the  filing  of  the  2017  financial  statements,  the  SEC  issued 
guidance  (SAB  118),  which  provided  a  one-year  measurement 
period for companies to finalize the accounting for the impact of 
the TCJA.

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. With respect to Ambac's domestic 
subsidiaries  subject  to  U.S.  tax,  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 maintains a full valuation allowance. The remaining 
net deferred tax liability of $40,130 is attributable to Ambac U.K.

NOL Usage 

Pursuant to the intercompany tax sharing agreement, 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 with the following NOL 
usage table, where the “Applicable Percentage” is applied to the 
aggregate amount of federal income tax liability that would have 
been paid if the Allocated NOLs were not available.  Pursuant to 
the Closing Agreement between Ambac and the Internal Revenue 
Service ("IRS"), the IRS will receive 12.5% of Tier C and 17.5% 
of Tier D payments, if made.

Any  net  operating  loss  carryforwards  ("NOLs")  generated  by 
Ambac Assurance after September 30, 2011 are utilized prior to 
any Allocated  NOLs  for  which  Tolling  Payments  will  be  due.  
Ambac Assurance utilized all of its current post determination date 
NOLs generated from September 30, 2011 through December 31, 
2018, generating cumulative taxable income of $1,486,879.  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.    Through  December 31,  2018,  Ambac 
Assurance utilized all of the  $479,000 Tier A NOL and $1,007,879 
of the $1,057,000 Tier B NOL resulting in Tolling Payments, net 
of applicable credits, of $100,145, of which $71,454 was paid to 
Ambac in 2016. and $28,691 was paid in 2017.  For the tax years 
ended December 31, 2017 and 2018, Ambac Assurance recorded 
additional estimated Tolling Payments of $30,496, and $13,885, 
respectively.  In May 2018 Ambac executed a waiver under the 
intercompany  tax  sharing  agreement  pursuant  to  which Ambac 
Assurance  was  relieved  of  the  requirement  to  make  $30,496
payment by June 1, 2018.  Ambac has also agreed to continue to 
defer the tolling payment for the use of net operating losses by 
Ambac Assurance until such time as OCI consent to the payment.  
The 2018 accrued tolling payment of $13,885  is also subject to 
OCI's review and consent.

As of December 31, 2018 Ambac had U.S. federal net operating 
loss tax carryforwards of approximately $3,423,704, which, if not 
utilized, will begin expiring in 2029, and will fully expire in 2032.  
The remaining balance of the NOL allocated to Ambac Assurance 
was $2,163,121 and Ambac was $1,260,583.

EMPLOYMENT BENEFIT PLANS 

Postretirement Health Care and Other Benefits: 

Ambac provides postretirement and postemployment / severance 
benefits, including health and life benefits for certain employees 
who meet certain age and service requirements. None of the plans 
are currently funded.  Postretirement and postemployment benefits 
expenses, including severance benefits paid, was $936, $5,223 and 
$9,465 for the years ended December 31, 2018, 2017 and 2016, 
respectively.

Effective August 1,  2005,  new  employees  were  not  eligible  for 
postretirement  benefits.  The  current  postretirement  benefit 
requires retirees to purchase their own medical insurance policy 
with a portion of their premium being reimbursed by Ambac. The 
unfunded  accumulated  postretirement  benefit  obligation  was 
$8,720 as of December 31, 2018. The assumed health care cost 
trend rates range from 5.4% in 2019, decreasing ratably to 4.5%
in 2025. 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, 
2018, by $170 and the 2018 benefit expense by $11. 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,  2018  by  $237  and  the  2018 
benefit expense by $17. 

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 plan. The rates used for the projected plan 
benefit obligations at the measurement date for December 31, 2018 
and 2017 were 4.00% and 3.50%, 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 
up to an additional 2% of compensation, subject to limits set by 
the Internal Revenue Code. The total cost of the Savings Incentive 
Plan was $1,029, $691 and $911 for the years December 31, 2018, 
2017 and 2016, respectively.

Incentive Compensation - Stock Units and Cash:

Incentive compensation is a key component of our compensation 
strategy. Our incentive compensation awards generally have two 
components: short term incentive compensation or annual bonuses 
and long term incentive plan awards.  Annual decisions with regard 
to incentive compensation are generally made in the first quarter 
of  each  year  and  are  based  on  Company  performance  and 
individual and business unit performance of the previous year.  For 
all employees, an allocation of incentive compensation is made 
between annual bonuses and LTIP awards.  Beginning for the 2016 
performance year, the annual bonus was settled via cash and vested 
restricted stock units for certain employees. 

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 1,972,068 shares are available for 
future grant as of December 31, 2018.

In  March  2014,  Ambac  developed  a  long  term  incentive 
compensation plan (“LTIP”) as a sub-plan of the 2013 Plan. The 
LTIP is intended to be an annual program that allows for both cash 
and  equity  performance  awards  to  certain  US  employees. 
Beginning with grants issued in 2017, the entire LTIP award was 
issued as equity performance awards to 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 
$1,096, $2,159 and $283 for the years ended December 31, 2018, 
2017 and 2016, respectively.

corresponding after-tax expense are as follows:

(1)  As  discussed  in  Note  2.  Basis  of  Presentation  and  Significant 
Accounting Policies , we adopted ASU 2016-09 as of January 1, 2017.  
One  of  the  provisions  of  this ASU  requires  entities  to  make  an 
accounting policy election with respect to forfeitures of share-based 
payment awards.  We elected to account for forfeitures as they occur 
and  adopted  this  provision  of  ASU  2016-09  using  a  modified 
retrospective  approach  resulting  in  recording  a  cumulative-effect 
adjustment to equity of $137.

Stock Options: 

Stock options were awarded in years prior to 2016 to directors that 
had 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.

stock options granted were $0 as of December 31, 2018.  No stock 
options were exercised during the years ended December 31, 2018, 
2017 and 2016, respectively.

Restricted Stock Units (“RSUs”):

RSUs are awarded annually to certain employees for (i) a portion 
of  their  annual  bonus  and  special  awards  for  exceptional 
performance  and  (ii)  a  portion  of  their  long  term  incentive 
compensation.    For  those  granted  in  connection  with  (i)  above, 
awards vest upon grant, but settlement is deferred, other than for 
employment  tax  withholdings,  into  two  equal  installments 
generally on the first and second anniversary date of the grant.  For 
those granted in connection with (ii) above, awards generally vest 
in  equal  installments  over  a  three  year  period.    Such  vesting  is 
expressly conditioned upon the respective employees 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 
unvested RSUs shall partially vest as of the date of such termination 
in an amount equal to the number of then outstanding unvested 
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, 2018, 645,028 RSUs remained outstanding, 
of which (i) 209,093 units required future service as a condition 
to the delivery of the underlying shares of common stock and (ii) 
435,935 units did not require future service and are deferred for 
future  settlement.    As  of  December 31,  2017,  221,803  RSUs 
remained outstanding, of which (i) 68,654 units required future 
service as a condition to the delivery of the underlying shares of 
common stock,and (ii) 153,149 units did not require future service 
and are deferred for future settlement.

(1)  When restricted stock unit awards issued by Ambac become taxable

employee’s  withholding  taxes.    For  the  year  ended  December  31, 
2018, Ambac purchased 22,929 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 
2018, 2017 and 2016 was $16.35, $20.22 and $14.34, respectively.  
As of December 31, 2018, there was $1,760 of total unrecognized 
compensation costs related to unvested RSUs granted. These costs 
are expected to be recognized over a weighted average period of 
1.8 years. The fair value for RSUs vested and delivered during the 
year ended December 31, 2018, 2017 and 2016 was $609, $2,536 
and $2,965, respectively.

Performance Stock Awards ("PSUs"):

Performance awards granted vest in 3 years and 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  pre-tax  income.  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  the  participant  meets  certain  minimum  service 
requirements, 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.  Settlement of the 2016 performance award shall 
be within 60 days after the end of the performance period, including 
those with a partial vesting.  2017 and 2018 performance awards, 
shall be settled within 75 days after the end of the performance 
period, including those with a partial vesting. 

In 2015, a performance award was granted to the former Chief 
Executive Officer.  This award vested on February 12, 2018 upon 
the emergence of the Segregated Account from rehabilitation.

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.  Ambac will relocate its 
executive office in the third quarter of 2019 and in January 2019, 
has entered into a sublease agreement at One World Trade Center, 
New York.    In  January  2019,   Ambac  has  sublet  the  remaining 
space at One State Street Plaza through its expiration date of 2029.  
Rent payments under the One State Street Plaza lease made through 
September  2019  will  result  in  the  periodic  reduction  of  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:

Litigation Against Ambac

Monterey Bay Military Housing, LLC, et al. v. Ambac Assurance 
Corporation, et al. (United States District Court, Northern District 
of California, San Jose Division, Case No. 17-cv-04992-BLF, filed 
August 28, 2017).  Plaintiffs, the corporate developers of various 
military housing projects, filed an amended complaint on October 
27, 2017 against Ambac Assurance, a former employee of Ambac 
Assurance, and certain unaffiliated persons and entities, asserting 
claims for (i) violation of 18 U.S.C §§ 1962(c) and 1962(d) (civil 
Racketeer  Influenced  and  Corrupt  Organizations Act  (“RICO”) 
and conspiracy to commit civil RICO), (ii) breach of fiduciary duty, 
(iii) aiding and abetting breach of fiduciary duty, (iv) fraudulent 
misrepresentation, (v) fraudulent concealment and (vi) conspiracy 
to commit fraud.  The claims relate to bonds and debt certificates 
(insured  by Ambac Assurance)  that  were  issued  to  finance  the 
renovation and construction of housing at certain military bases. 
Plaintiffs allege that defendants secretly conspired to overcharge 
plaintiffs for the financing of the projects and directed the excess 
profits to themselves.  Plaintiffs allege defendants generated these 
excess  profits  by  supposedly  charging  inflated  interest  rates, 
manipulating  “shadow  ratings,”  charging  unnecessary  fees, 
rigging  the  Guaranteed  Investment  Contract  (“GIC”)  bidding 
process,  and  hiding  evidence  of  their  alleged  wrongdoing. 
Plaintiffs  seek,  among  other  things,  compensatory  damages, 
disgorgement  of  profits  and  fees,  punitive  damages,  trebled 
damages and attorneys’ fees.  Ambac and the other defendants filed 
motions to dismiss the amended complaint on November 13, 2017. 
On July 17, 2018, the court granted Ambac Assurance’s and the 
other defendants’ motion to dismiss the first amended complaint 
without prejudice. On December 17, 2018, Plaintiffs filed a second 
amended  complaint.   Ambac  and  the  other  defendants  filed  a 
motion to dismiss the second amended complaint on February 15, 
2019.

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  and  have 
commenced, or threatened to commence, litigation to resolve these 
differences. 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.

present or former employees. Although the Company’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  the  Company  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 the Company 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

Litigation Filed or Joined 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

Puerto Rico:

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 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 moved 
to  dismiss  on  January  29,  2016.  On  October  4,  2016,  the  court 
denied the Defendants’ motions to dismiss. 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 was 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. PROMESA’s litigation stay expired on May 2, 
2017. On May 3, 2017, the Financial Oversight and Management 

Board  for  the  Commonwealth  of  Puerto  Rico  (the  “Oversight 
Board”) filed a petition to adjust the Commonwealth’s debts under 
Title III of PROMESA, resulting in an automatic stay of litigation 
against the Commonwealth. On May 17, 2017, the court issued an 
order staying this case until further order of the court.

Ambac  Assurance  Corporation  v.  Puerto  Rico  Highways  and 
Transportation Authority (United States District Court, District of 
Puerto  Rico,  No.  16-cv-1893,  filed  May  10,  2016).  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. Ambac Assurance also filed related 
motions  seeking  the  appointment  of  a  provisional  receiver  for 
PRHTA and expedited discovery. On May 21, 2017, the Oversight 
Board filed a petition to adjust PRHTA’s debts under Title III of 
PROMESA,  resulting  in  an  automatic  stay  of  litigation  against 
PRHTA. On May 24, 2017, the court issued an order staying this 
case until further order of the court.

Lex Claims, LLC et al. v. Alejandro Garcia Padilla et al. (United 
States District Court, District of Puerto Rico, No. 16-2374, filed 
July 20, 2016). On October 7, 2016, certain General Obligation 
bondholder Plaintiffs in an action to which Ambac Assurance was 
not  then  a  party  filed  a  motion  for  leave  to  amend  an  existing 
complaint,  adding 
the  Puerto  Rico  Sales  Tax  Financing 
Corporation ("COFINA"), COFINA’s executive director, and the 
trustee  for  the  COFINA  bonds  as  Defendants,  and  asserting 
numerous claims that challenged 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. On February 17, 2017, the court permitted Ambac 
Assurance to intervene.  On May 3, 2017, a petition under Title III 
of PROMESA was filed on behalf of the Commonwealth of Puerto 
Rico, and on May 5, 2017, a petition under Title III of PROMESA 
was filed on behalf of COFINA, resulting in an automatic stay of 
litigation against the Commonwealth and COFINA (respectively).  
On May 17, 2017, the court issued an order staying this case until 
further  order  of  the  court.  On  October  19,  2018,  the  Oversight 
Board filed (i) a disclosure statement and a plan of adjustment for 
COFINA  (the  “COFINA  Plan”)  in  the  COFINA  Title  III  case 
incorporating  a 
the 
Commonwealth and COFINA concerning entitlement to sales and 
use  taxes  (the  “Commonwealth-COFINA  Dispute”),  and  (ii)  a 
motion under Bankruptcy Rule 9019 in the Commonwealth Title 
III  case  for  approval  of  the  settlement  of  the  Commonwealth-
COFINA Dispute (the “9019 Motion”). On February 4, 2019 the 
District  Court  granted  the  9019  Motion  and  confirmed  the 
COFINA  Plan,  which  resolves  the  dispute  in  this  case.  The 
COFINA Plan became effective on February 12, 2019. Following 
confirmation of the COFINA Plan, several parties filed notices of 
appeal of the District Court’s confirmation order.

Economic Growth Plan (the "FEGP") and a recently enacted statute 
called the “Fiscal Plan Compliance Law” are unconstitutional and 
unlawful  because  they  violate  the  Contracts,  Takings,  and  Due 
Process  Clauses  of  the  U.S.  Constitution,  are  preempted  by 
PROMESA, and are unlawful transfers of property from COFINA 
to the Commonwealth in violation of PROMESA. On May 3, 2017, 
a petition under Title III of PROMESA was filed on behalf of the 
Commonwealth of Puerto Rico, and on May 5, 2017, a petition 
under Title  III  of  PROMESA  was  filed  on  behalf  of  COFINA, 
resulting in an automatic stay of litigation against COFINA.  On 
May  17,  2017,  the  court  issued  an  order  staying  this  case  until 
further order of the court. On February 4, 2019, the District Court 
granted the 9019 Motion and confirmed the COFINA Plan.  The 
COFINA Plan became effective on February 12, 2019. Following 
confirmation of the COFINA Plan, several parties filed notices of 
appeal  of  the  District  Court’s  confirmation  order.  Ambac 
Assurance anticipates that this case will be voluntarily dismissed 
in the near future given the effectiveness of the COFINA Plan.

Ambac Assurance Corporation v. Puerto Rico, et al. (United States 
District Court, District of Puerto Rico, No. 17-1568, filed May 2, 
2017).  On  May  2,  2017,  Ambac  Assurance  filed  a  complaint 
alleging  that  various  moratorium  laws  and  executive  orders 
enacted by the Commonwealth to claw back funds from the Puerto 
Rico Infrastructure Financing Authority ("PRIFA"), PRHTA, and 
Puerto Rico Convention Center District Authority ("PRCCDA") 
bonds violate the Contracts, Takings, and Due Process Clauses of 
the  U.S.  Constitution,  are  preempted  by  PROMESA,  and 
unlawfully transfer PRHTA, PRCCDA, and PRIFA property to the 
Commonwealth.  On  May  3,  2017,  a  petition  under  Title  III  of 
PROMESA was filed on behalf of the Commonwealth of Puerto 
Rico and on May 21, 2017, a petition under Title III of PROMESA 
was filed on behalf of PRHTA, resulting in an automatic stay of 
litigation against the Commonwealth and PRHTA (respectively).  
On May 17, 2017, the court issued an order staying this case until 
further order of the court.

Ambac Assurance Corporation v. U.S. Department of Treasury et 
al. (United States District Court, District of Columbia, No. 17-809, 
filed May 2, 2017). On May 2, 2017, Ambac Assurance filed a 
complaint  against  the  U.S.  Department  of Treasury  and  Steven 
Mnuchin,  in  his  official  capacity  as  Secretary  of  the  Treasury, 
alleging that Puerto Rico’s ongoing diversion of rum taxes from 
PRIFA violates the Contracts, Takings, and Due Process Clauses 
of the U.S. Constitution, and seeking an equitable lien on all rum 
taxes possessed by the U.S. Treasury, and an injunction preventing 
their transfer to the Commonwealth.  On May 3, 2017, a petition 
under  Title  III  of  PROMESA  was  filed  on  behalf  of  the 
Commonwealth of Puerto Rico.  On May 24, 2017, the Oversight 
Board filed a statement requesting that the court take notice of the 
stay resulting from the Commonwealth’s Title III filing.  On May 
25, 2017, the court issued an order staying this case pending the 
final disposition of the Title III proceedings.

Ambac  Assurance  Corporation  v.  Bank  of  New  York  Mellon 
(United States District Court, Southern District of New York.  No. 
1:17-cv-03804,  filed  May  2,  2017).  On  May  2,  2017, Ambac 
Assurance filed a complaint in New York State Supreme Court, 
New York County, against the trustee for the COFINA bonds, Bank 
of  New  York  Mellon  ("BNY"),  alleging  breach  of  fiduciary, 
contractual,  and  other  duties  for  failing  to  adequately  and 

appropriately  protect  the  holders  of  certain Ambac Assurance-
insured senior COFINA bonds. On May 19, 2017, BNY filed a 
notice of removal of this action from New York state court to the 
United States District Court for the Southern District of New York. 
On May 30, 2017, the United States District Court for the District 
of Puerto Rico entered an order in an adversary proceeding brought 
by BNY (No. 1:17-ap-00133) staying this litigation pending further 
order of the court. The COFINA Plan became effective on February 
12, 2019, and, pursuant to the District Court’s confirmation order, 
this litigation is permitted to continue, with Ambac’s claims against 
BNYM  being  limited  to  those  for  gross  negligence,  willful 
misconduct and intentional fraud. Following confirmation of the 
COFINA Plan, several parties filed notices of appeal of the District 
Court’s confirmation order.

Bank of New York Mellon v. COFINA, et al. (United States District 
Court, District of Puerto Rico, No. 1:17-ap-00133, filed May 16, 
2017).  On May 16, 2017, BNY filed an interpleader action styled 
as an adversary proceeding against COFINA and certain creditors 
of  COFINA,  including  Ambac  Assurance,  that  have  made 
competing claims of entitlement to funds held by BNY in order to 
determine the parties’ respective entitlements to the funds.  BNY 
also sought a release of liability in association with the COFINA 
funds  in  its  possession..    On  September  27,  2018,  the  court 
terminated  competing  motions  for  summary  judgment  without 
prejudice in light of the pending agreement in principle between 
the agent for COFINA and the agent for the Commonwealth in 
adversary  proceeding  no.  1:17-ap-00257  (the  “Commonwealth-
COFINA Dispute,” discussed below).  On October 19, 2018, the 
Oversight Board filed (i) a disclosure statement and the COFINA 
Plan in the COFINA Title III case incorporating a resolution of the 
Commonwealth-COFINA Dispute, and (ii) the 9019 Motion in the 
Commonwealth Title III case for approval of the settlement of the 
Commonwealth-COFINA  Dispute.  On  February  4,  2019  the 
District  Court  granted  the  9019  Motion  and  confirmed  the 
COFINA  Plan,  which  resolves  the  dispute  in  this  case.    The 
COFINA Plan became effective on February 12, 2019. Following 
confirmation of the COFINA Plan, several parties filed notices of 
appeal of the District Court’s confirmation order. On February 20, 
2019, on the joint motion of BNY and COFINA, the District Court 
dismissed this case with prejudice.

Ambac Assurance Corporation v. Puerto Rico, et al. (United States 
District Court, District of Puerto Rico, No. 1:17-ap-00159, filed 
June  8,  2017).    On  June  8,  2017,  Ambac  Assurance  filed  an 
adversary complaint in the Commonwealth’s Title III case against 
the Commonwealth, PRHTA, the Oversight Board, AAFAF, and 
other  Commonwealth  government  officers.   Ambac Assurance 
challenges  the  Commonwealth’s  clawback  of  funds  from  the 
PRIFA,  PRHTA,  and  PRCCDA  bonds  under  the  Contracts, 
Takings, and Due Process Clauses of the U.S. Constitution and 
under PROMESA.  The complaint further seeks a declaration that 
revenues  pledged  to  the  PRHTA  bonds  are  “special  revenues” 
under  Sections  922  and  928  of  the  Bankruptcy  Code,  and  an 
injunction  compelling  Defendants  to  remit  the  pledged  special 
revenues to PRHTA for payment of the PRHTA bonds.  On July 
7, 2017, Ambac Assurance filed an amended complaint that added 
an additional claim for relief: a declaration that the funds held in 
the  PRHTA  reserve  accounts  are  property  of  the  PRHTA 
bondholders.  On  July  28,  2017,  Defendants  moved  to  dismiss 
Ambac Assurance’s complaint, which Ambac Assurance opposed.

On  February  27,  2018,  the  District  Court  granted  Defendants’ 
motion to dismiss. On March 9, 2018, Ambac Assurance appealed 
this ruling to the First Circuit Court of Appeals. Oral argument was 
held before the First Circuit on January 15, 2019.

Official  Committee  of  Unsecured  Creditors  v.  Whyte  (United 
States District Court, District of Puerto Rico, No. 1:17-ap-00257, 
filed September 8, 2017) (the Commonwealth-COFINA Dispute).  
On August 10, 2017, the court approved a stipulation between the 
Oversight  Board,  the  Commonwealth,  COFINA,  and  certain 
creditor  parties,  including  Ambac  Assurance,  to  resolve  the 
Commonwealth-COFINA Dispute regarding entitlement to sales 
and use taxes.  The stipulation provided that separate agents for 
COFINA and the Commonwealth would litigate the dispute while 
preserving  the  ability  of  interested  parties,  to  participate  in  the 
litigation.  On September 8, 2017, the Commonwealth Agent filed 
an adversary proceeding against the COFINA Agent challenging 
the COFINA structure on various grounds.  The Commonwealth 
Agent  filed  a  revised  complaint  on  October  25,  2017,  making 
technical corrections to the original complaint.  Ambac Assurance 
made a motion to intervene in this action, which the court granted 
on  November  21,  2017.  The  Commonwealth  Agent  filed  an 
amended  complaint  on  January  16,  2018,  largely  re-stating  its 
original causes of action to fall within the parameters of the dispute 
set by the court.  After extensive motion practice, on September 
27,  2018,  the  court  terminated  competing  summary  judgment 
motions  without  prejudice  in  light  of  a  pending  agreement  in 
principle between the Commonwealth Agent and COFINA Agent.  
On October 19, 2018, the Oversight Board filed (i) a disclosure 
statement  and  the  COFINA  Plan  in  the  COFINA  Title  III  case 
incorporating  a  resolution  of  the  Commonwealth-COFINA 
Dispute, and (ii) a the 9019 Motion in the Commonwealth Title III 
case for approval of the settlement of the Commonwealth-COFINA 
Dispute. On February 4, 2019, the District Court granted the 9019 
Motion  and  confirmed  the  COFINA  Plan,  which  resolves  the 
dispute  in  this  case.    The  COFINA  Plan  became  effective  on 
February 12, 2019. Following confirmation of the COFINA Plan, 
several  parties  filed  notices  of  appeal  of  the  District  Court’s 
confirmation order.

Student Loans Exposure:

CFPB v. Nat’l Collegiate Master Student Loan Trust (United States 
District Court, District of Delaware, Case No. 1:17-cv-01323, filed 
September 18, 2017). The Consumer Financial Protection Bureau 
(“CFPB”)  filed  a  complaint  against  fifteen  National  Collegiate 
Student  Loan  Trusts,  regarding  alleged  improprieties  and 
deficiencies in servicing practices.   Simultaneous with the filing 
of its complaint, CFPB also filed a motion for entry of a proposed 
consent  judgment  that  would  grant  monetary  damages  and 
injunctive relief against the Trusts. Ambac Assurance guaranteed 
certain securities issued by three of the Trusts and indirectly insures 
six other Trusts.  Ambac Assurance filed a motion to intervene in 
the action on September 20, 2017. On September 20, 2018, the 
case was reassigned to a new judge, who invited additional letter 
submissions from the parties.  Ambac Assurance submitted a letter 
on September 28, 2018, reiterating its request to intervene in the 
action.  The CFPB also submitted a letter, which asserted that the 
court  can  resolve  the  outstanding  intervention  motions  on  the 
papers.  In additional submissions, the CFPB and a firm purporting 
to  represent  the  Defendant  Trusts  argued  that  the  court  should 

resolve a dispute relating to the payment of counsel fees out of 
Trust assets, so that the Trusts can secure representation for the 
case.  On October 19, 2018, the court granted Ambac’s motion to 
intervene.  On November 29, 2018, following submissions from 
the parties regarding the CFPB’s motion for entry of the proposed 
consent judgment and regarding discovery necessary to respond 
to  the  motion,  the  court  set  a  bifurcated  discovery  and  briefing 
schedule.    Discovery  is  now  proceeding  as  to  certain  threshold 
issues, to be followed by briefing on the CFPB’s motion to approve 
the consent judgment.

Nat’l  Collegiate  Master  Student  Loan  Trust  v.  Pa.  Higher 
Education  Assistance  Agency  (PHEAA)  (Delaware  Court  of 
Chancery, C.A. No. 12111-VCS, filed March 21, 2016).  Plaintiffs 
purporting to act on behalf of fifteen National Collegiate Student 
Loan Trusts filed a lawsuit against PHEAA, a servicer of loans in 
the  Trusts,  alleging  improprieties  and  deficiencies  in  servicing 
practices and seeking an order compelling PHEAA to submit to an 
emergency audit.  PHEAA submitted papers contesting the validity 
of certain transfers to Plaintiffs of beneficial ownership interests 
in  the  Trusts.   In  addition,  the  Owner  Trustee  of  the  Trusts, 
Wilmington  Trust  Company,  WTC,  citing 
irreconcilable 
differences  with  Plaintiffs,  has  resigned  from  its  role  as  Owner 
Trustee and moved for appointment of a successor Owner Trustee.  
On  October  9,  2017,  the  court  directed  the  parties  to  meet  and 
confer to develop a process for selecting an interim Owner Trustee.  
Ambac Assurance guaranteed certain securities issued by three of 
the  Trusts  and  indirectly  insures  certain  securities  in  six  other 
Trusts.  Ambac Assurance filed a motion to intervene in the action 
on  October  23,  2017,  for  the  limited  purpose  of  being  heard 
regarding  the  appointment  of  a  successor  Owner  Trustee  and 
regarding  WTC’s  contractual  commitment  and  obligation  to 
remain in that role until such appointment is made. On October 
30, 2017, the court denied without prejudice a stipulation filed by 
Plaintiffs and WTC purporting to address the Owner Trustee issue, 
and  instructed  that  all  interested  parties  be  given  notice  and  an 
opportunity to participate in discussions to formulate a process for 
selecting a successor Owner Trustee.  On November 7, 2017, the 
court ruled in Plaintiffs’ favor and confirmed the validity of the 
ownership transfers that PHEAA had disputed.  On January 12, 
2018, Plaintiffs filed a motion for injunctive or declaratory relief 
requiring WTC, as Owner Trustee, and GSS Data Services, Inc., 
as Administrator, to resume processing for payment bills submitted 
by lawyers purporting to act on the Trusts’ behalf.   At a hearing 
on  April  3,  2018,  the  court  denied  Plaintiffs’  motion  without 
prejudice and on April 16, 2018 entered an order memorializing 
its oral ruling. The court also granted Ambac Assurance’s motion 
to  intervene  on April  10,  2018  and Ambac Assurance  filed  its 
complaint in intervention on April 16, 2018.

On  June  15,  2018,  the  Owner  Trustee  filed  a  stipulation  and 
proposed  order  addressing  the  selection  of  a  Successor  Owner 
Trustee.   Among  other  provisions,  the  stipulation  calls  for  the 
appointment of a Special Master to adjudicate disputes regarding 
Owner Instructions, and raises the annual expense caps that apply 
to  the  Owner  Trustee  and  Indenture  Trustee.    The  court  heard 
arguments on the stipulation on September 21, 2018, ruled that a 
Special  Master  would  be  appointed,  and  invited  the  parties  to 
submit a revised stipulation and proposed order to conform to the 
court’s rulings at the hearing.  After considering competing draft 
orders  submitted  by  the  Owner  Trustee  and  Plaintiffs,  on

November  14,  2018,  the  court  issued  an  order  appointing  Hon. 
Joseph J. Farnan, Jr. as Special Master and granting him authority 
to resolve non-dispositive disputes among the parties, including 
disputes concerning instructions to the Owner Trustee.  

RMBS Litigation:

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  has 
asserted claims for breach of contract, fraudulent inducement, 
indemnification,  reimbursement  and  has  requested  the 
repurchase of loans that breach representations and warranties 
as required under the contracts. On July 18, 2013 the court 
granted  in  part  and  denied  in  part  Defendants’  motion  to 
dismiss (filed on July 13, 2012).  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  denied  dismissal  of  Ambac 
Assurance’s  other  contractual  claims  and  fraudulent 
inducement claim. 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’s Second Amended Complaint, filed on May 28, 
2013,  asserted  claims  against  Countrywide  and  Bank  of 
America (as successor to Countrywide’s liabilities) for breach 
of  contract,  fraudulent  inducement,  indemnification  and 
reimbursement, and breach of representations and warranties.  
Ambac Assurance also requested the repurchase of loans that 
breach representations and warranties as required under the 
contracts. On May 1, 2015, the parties filed motions for partial 
summary  judgment  regarding  Ambac  Assurance’s  claims 
against  Countrywide  (primary-liability  claims)  and  its 
secondary-liability  claims  against  Bank  of  America.  In 
decisions issued on October 27, 2015, the court granted in 
part  and  denied  in  part  the  parties’  respective  summary 
judgment  motions  regarding  Ambac  Assurance’s  claims 
against Countrywide and granted Ambac Assurance’s motion 
for  partial  summary  judgment  on  its  secondary-liability 
claims  against  Bank  of  America  and  denied  Bank  of 
America’s  motion  for  summary  judgment  regarding  this 
claim.  Each  party  appealed  certain  aspects  of  the  court’s 
decisions  to  the  New  York  Appellate  Division,  First 
Department.   On May 16, 2017, the First Department issued 
rulings in both appeals, reversing a number of rulings that the 
trial court had made and affirming other rulings.  On June 15, 

2017,  Ambac  Assurance  sought  leave  from  the  First 
Department  to  appeal  certain  rulings  in  its  May  16,  2017 
decision to the Court of Appeals, which the First Department 
granted  on  July  25,  2017.  On  June  27,  2018,  the  Court  of 
Appeals denied Ambac Assurance’s appeal and affirmed the 
rulings of the First Department. Defendants filed certain pre-
trial motions on August 22, 2018 seeking to (1) strike Ambac 
Assurance’s jury demand for its fraudulent inducement claim; 
(2) strike Ambac Assurance’s jury demand for its successor 
liability claim; (3) bifurcate the trials for Ambac Assurance’s 
primary and successor liability claims; (4) limit the loans for 
which Ambac Assurance may seek to recover damages; and 
(5) preclude Ambac Assurance from using sampling to prove 
liability or damages for breach of contract.  On October 2, 
2018  Countrywide  moved  to  dismiss  Ambac  Assurance’s 
fraudulent-inducement  claim  as  duplicative  of  its  contract 
claim.  On December 30, 2018, the court denied all six of 
Defendants’ pre-trial motions in their entirety.  Defendants 
filed  notices  of  appeal  of  the  court's  December  30,  2018 
decisions.  On January 24, 2019, the court ordered that trial 
be  put  off  until  the  First  Department  resolves  Defendants’ 
appeals from the court’s denial of their pre-trial motions, on 
the condition that the appeals are perfected for the May 2019 
Term at the First Department. Defendants filed their opening 
appeal briefs in the First Department on February 19, 2019.

•  Ambac Assurance Corporation and The Segregated Account 
of  Ambac  Assurance  Corporation  v.  Nomura  Credit  & 
Capital,  Inc.  and  Nomura  Holding America  Inc.  (Supreme 
Court of the State of New York, County of New York, Case 
No. 651359/2013, filed on April 15, 2013). Ambac Assurance 
has asserted claims for material breach of contract and has 
requested the repurchase of loans that breach representations 
and  warranties  under  the  contracts. Ambac Assurance  also 
asserted alter ego claims against Nomura Holding America, 
Inc. Defendants filed a motion to dismiss on July 12, 2013. 
On September 22, 2014, plaintiffs filed an amended complaint 
which added (in addition to the claims previously asserted) a 
claim  for  fraudulent  inducement.  On  October  31,  2014 
defendants filed a motion to strike the amended complaint 
and on November 10, 2014 also filed a motion to dismiss the 
fraudulent-inducement  claim.    On  June  3,  2015,  the  court 
denied  defendants’  July  2013  motion  to  dismiss  Ambac 
Assurance’s  claim  for  breaches  of  representations  and 
warranties,  but  granted  the  defendants’  motion  to  dismiss 
Ambac  Assurance’s  claims  for  breach  of  the  repurchase 
protocol and for alter ego liability against Nomura Holding. 
On December 29, 2016, the court denied Nomura’s motion 
to  strike  Ambac  Assurance’s  amended  complaint  and  its 
motion to dismiss the fraudulent-inducement claim.  Nomura 
appealed the June 2015 decision to the extent it denied its 
motion to dismiss, filing its opening appellate brief on March 
23,  2017.    On  December  7,  2017,  the  First  Department 
affirmed the trial court’s June 3, 2015 decision. Discovery is 
ongoing.

of  Ambac  Assurance  Corporation  v.  Countrywide  Home 
Loans, Inc. (Supreme Court of the State of New York, County 
of New York, Case No. 652321/2015, filed on June 30, 2015).

Court  (the  “2015  New  York  Action”),  asserting  claims 
identical  to  claims  they  asserted  in  a  litigation  filed  on 
December  30,  2014  in  Wisconsin  Circuit  Court  for  Dane 
County,  Case  No  14  CV  3511  (the  “Wisconsin Action”). 
Specifically, in each action Ambac Assurance asserted a claim 
for fraudulent inducement in connection with its 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. 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. Countrywide opposed plaintiffs’ motion to stay and 
on August 10, 2015, Countrywide filed a motion to dismiss 
the  complaint.  On  September  20,  2016,  the  court  granted 
Ambac Assurance’s motion to stay and held Countrywide’s 
motion  to  dismiss  in  abeyance  pending  resolution  of  the 
Wisconsin Action.  Following the dismissal of the Wisconsin 
Action on March 13, 2018, the court in the 2015 New York 
Action  vacated  its  stay  on  March  30,  2018,  and  restored 
Countrywide’s motion to dismiss to the calendar.  The parties 
submitted  supplemental  letter  briefs  on  April  11,  2018 
addressing newly-issued relevant authority.

•  Ambac Assurance Corporation and the Segregated Account 
of  Ambac  Assurance  Corporation  v.  Countrywide  Home 
Loans,  Inc.,  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  asserted  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.  On December 20, 2016, the court denied 
defendants’ motion to dismiss.  Discovery is ongoing.

•  Ambac  Assurance  Corporation  v.  U.S.  Bank  National 
Association (United States District Court, Southern District 
of New York, Docket No. 18-cv-5182 (LGS), filed June 8, 
2018  (the  “SDNY Action”));  In  the  matter  of  HarborView 
Mortgage Loan Trust 2005-10 (Minnesota state court, Docket 
No. 27-TR-CV-17-32 (the “Minnesota Action”)).  These two 
actions  relate  to  U.S.  Bank  National Association’s  (“U.S. 
Bank”)  acceptance  of  a  proposed  settlement  in  a  separate 
litigation that U.S. Bank is prosecuting, as trustee, related to 
the  Harborview  Mortgage  Loan  Trust,  Series  2005-10 
(“Harborview  2005-10”),  a  residential  mortgage-backed 
securitization  for  which  Ambac  Assurance 
issued  an 
insurance policy.  On March 6, 2017, U.S. Bank filed a petition 
commencing  the  Minnesota  Action,  a  trust  instruction 
proceeding in Minnesota state court concerning the proposed 
settlement, and on June 12, 2017, U.S. Bank filed an amended 
petition.  Ambac Assurance  filed  a  motion  to  dismiss  the 
Minnesota Action. On November 13, 2017, the court denied 
Ambac Assurance’s motion to dismiss the Minnesota Action. 
On  February  7,  2018,  Ambac  Assurance  appealed  this 
decision, and on September 4, 2018, the Minnesota Court of 
Appeals affirmed the lower court's decision. On September 

17, 2018, Ambac Assurance filed a petition for review with 
the  Minnesota  Supreme  Court,  which  was  denied  on 
November  13,  2018.    On  February  11,  2019,  Ambac 
Assurance filed a petition for certiorari with the United States 
Supreme Court.   On September 6, 2018, the court granted 
U.S.  Bank's  motion  for  leave  to  file  a  Second  Amended 
Petition  seeking  approval  of  its  acceptance  of  a  proposed 
settlement to settle the separate litigation being prosecuted by 
U.S. Bank, as Trustee.  On September 6, 2018, U.S. Bank 
filed its Second Amended Petition, and Ambac Assurance and 
certain  other  certificateholders  objected  to,  or  otherwise 
responded to, the petition. Discovery in the Minnesota Action 
is  ongoing.    On  June  8,  2018, Ambac Assurance  filed  the 
SDNY Action  asserting  claims  arising  out  of  U.S.  Bank’s 
acceptance of the proposed settlement and treatment of trust 
recoveries.  Ambac Assurance asserts claims for declaratory 
judgment, breach of contract, and breach of fiduciary duty.  
On November 20, 2018, U.S. Bank filed a motion to dismiss 
the  complaint,  which  Ambac  Assurance  opposed  on 
December 18, 2018.  The motion remains pending.  Discovery 
in the SDNY Action is stayed.

•  Ambac Assurance Corporation and The Segregated Account 
of  Ambac  Assurance  Corporation  v.  U.S.  Bank  National 
Association (United States District Court, Southern District 
of New York, Docket No. 17-cv-02614, filed April 11, 2017).  
Ambac Assurance has asserted claims for breach of contract, 
breach of fiduciary duty, declaratory judgment, and violation 
of  the  Streit Act  in  connection  with  defendant’s  failure  to 
enforce rights and remedies and defendant’s treatment of trust 
recoveries,  as  trustee  of  five  residential  mortgage-backed 
securitizations for which Ambac Assurance issued insurance 
policies. On September 15, 2017, U.S. Bank filed a motion 
to dismiss.  On June 29, 2018, the court granted in part and 
denied  in  part  U.S.  Bank’s  motion  to  dismiss.    The  court 
dismissed  the  breach-of-fiduciary  duty  claim  in  part  as 
duplicative  of  the  breach-of-contract  claim;  dismissed  the 
breach-of-contract claim as untimely only to the extent that 
it  was  premised  on  U.S.  Bank's  obligation  to  certify  that 
mortgage documents were properly delivered to the Trusts; 
dismissed  the  Streit Act  claims;  and  otherwise  denied  the 
motion to dismiss. Discovery is ongoing. 

•  In re application of Deutsche Bank National Trust Company 
as Trustee of the Harborview Mortgage Loan Trust Mortgage 
Loan  Pass-Through  Certificates,  Series  2006-9  (Supreme 
Court of the State of New York, County of New York, No. 
654208/2018), filed August 23, 2018 (the “Trust Instruction 
Proceeding”). This action relates to Deutsche Bank National 
Trust Company’s (“DBNT”) proposed settlement of claims 
related to the Harborview Mortgage Loan Trust Series 2006-9 
(“Harborview 2006-09”).  On August 23, 2018, DBNT filed 
a  Petition  commencing  the  Trust  Instruction  Proceeding, 
seeking judicial instruction pursuant to CPLR Article 77, inter 
alia, to accept the proposed settlement with respect of claims 
relating to Harborview 2006-9. On September 6, 2018, the 
court entered an Order to Show Cause, setting out procedures 
for DBNT to give notice of the proceedings and for interested 
persons to appear.  On November 2, 2018, Ambac Assurance 
and  other  interested  persons  filed  notices  of  intention  to 
appear and answers to DBNT’s  petition, and on November 
29, 2018  various parties filed responses to answers.   In its

answer, Ambac Assurance opposed DBNT’s request for an 
order instructing it to accept the proposed settlement on the 
basis  that  DBNT  breached  its  obligations  by  failing  to 
investigate  and  enforce  breaches  of  representations  and 
warranties  in  Harborview  2006-09,  failing  to  immediately 
reject the proposed settlement, and instituting an inadequate 
certificateholder approval process. Ambac  sought a period 
of discovery before resolution on the merits. 

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.  The presiding judge approved the settlement in August 
of 2014.  A fair fund has been established to distribute the $285,000 
(plus  $2,550  received  from  a  related  proceeding).  RCB  Fund 
Services  (the  “Distribution  Agent”)  has  been  appointed  as 
distribution agent for the fund and has invited investor participants 
in  the  CDO  transaction  to  provide  information  regarding  their 
investments  in  the  CDO  transaction.   Ambac Assurance  filed  a 
submission with the requested information on February 28, 2018.  
The Distribution Agent, in consultation with the SEC, is to develop 
a distribution plan for the fair fund, which will be filed with the 
Court and will be subject to a comment period.  The SEC filed a 
status report on August 13, 2018 to update the court on the process 
relating to the distribution plan.  The Distribution Agent stated that 
it intended to complete its review of the submissions it received 
from investors by the end of 2018.  Following completion of its 

review, the Distribution Agent will formulate a plan of distribution, 
which will then be reviewed by the SEC prior to being filed with 
the court.  The submission states that Distribution Agent expects 
to file the plan of distribution and distribute the funds in the first 
quarter of 2019.  There is no guarantee that there will actually be 
a  first  quarter  2019  distribution  as  it  depends  on  whether  any 
objections are filed to the plan of distribution and court approval.  
While there can be no assurance as what the distribution plan will 
provide, or the timing or substance of what the court 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.

NECA-IBEW Health & Welfare Fund v. Goldman, Sachs & Co., 
et al., (United States District Court for Southern District of New 
York,  No.  1:08-cv-10783-LAP)  and Police  and  Fire  Retirement 
System  of  the  City  of  Detroit  v.  Goldman,  Sachs  &  Co.  et 
al. (United States District Court for the Southern District of New 
York,  No.  10  Civ.  4429-LAP).   In  this  class  action,  Plaintiffs 
alleged  that  the  offering  documents  for  various  residential 
mortgage-backed  securities  sold  by  Goldman  Sachs  entities  in 
2007 and 2008 contained false and misleading statements.  The 
parties  to  the  litigation  reached  a  negotiated  settlement  for 
$272,000.  The settlement class approved by the court included all 
persons who prior to December 11, 2008 purchased or otherwise 
acquired  any  of  the  securities  at  issue  in  the  actions  and  were 
damaged 
its  subsidiaries 
purchased or otherwise acquired certain securities at issue in the 
class  action  and  were  thereby  included  in  the  settlement  class. 
Ambac submitted a claim form and in November 2018 received a 
distribution of approximately $26,721.

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, 
2018  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, 2018, 
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, 2018 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.  

Changes in Internal Control Over Financial Reporting.  There 
were no changes in the Company’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 2018 that 
have  materially  affected,  or  are  reasonably  likely  to  materially 
affect, Ambac's internal control over financial reporting.

disclosure.

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, 2018 and 2017 and 
for the three years in the period ended December 31, 2018, should be read in conjunction with the consolidated financial statements of Ambac 
Financial Group, Inc. and Subsidiaries and the notes thereto included in this 2018 Annual Report on Form 10-K for the year ended December 31, 
2018.

Ambac, headquartered in New York City, is a financial services holding company incorporated in the state of Delaware on April 29, 1991. 

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, 2018 Ambac had a U.S. loss carryforwards totaling 
$3,423,704, which, if not utilized, will begin expiring in 2029, and will fully expire in 2032.  The net operating loss carryforwards ("NOLs") 
allocable to AFG as of December 31, 2018 were $1,260,583.

Pursuant to the intercompany tax sharing agreement, 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, 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, 2018
(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 $1,486,879, which utilized all of the $479,000 allocated Tier A NOL 
and $1,007,879 of the $1,057,000 allocated Tier B NOL and resulted in accrued Tolling Payments, net of applicable credits.  Of the 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.

At December 31, 2018, $44,381 of tolling payments are owed by Ambac Assurance to Ambac.  In May 2018 Ambac executed a waiver under 
the intercompany tax sharing agreement pursuant to which Ambac Assurance was relieved of the requirement to make the  $30,496 payment 
for the 2017 tax year by June 1, 2018 until such time as OCI consents to the payment.  The 2018 accrued tolling payment of $13,885 is also 
subject to OCI's consent.

Ambac reports two non-GAAP financial measures: Adjusted Earnings and 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.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. Below are reconciliations of net income (loss) attributable to common stockholders to the non-GAAP measure of 
Adjusted Earnings (Losses) and Total Ambac Financial Group, Inc. stockholders’ equity per share ("Book Value") to the non-GAAP measure of Adjusted 
Book Value per share.  Each of the reconciling items is more fully defined in our 2018 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.

(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 statement 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 adjustment to conform to the methodology as such amounts were not material.

(2)  Totals may not add due to rounding differences.
