> DEAR FELLOW SHAREHOLDERS

“   As I reflect on our shared experience 
brought about by the pandemic, I 
am grateful for the demonstration of 
community, the perseverance of our 
employees and Board of Directors  
and their commitment to progressing  
our strategic initiatives.”

CLAUDE LeBLANC
President and Chief Executive Officer

This year has been one of significant challenges that have tested our collective resolve. As I reflect on  
our shared experience brought about by the pandemic, I am grateful for the demonstration of community,  
the perseverance of our employees and Board of Directors and their commitment to progressing our  
strategic initiatives.

As we navigated through the challenges posed by the pandemic, the health, safety and well-being of 
our employees was always a top priority and we took immediate steps to protect our staff. In active dialogue 
with our Board and key service providers, we implemented significant measures to ensure the safety of our 
employees and uninterrupted business operations, including: 

n    A swift and smooth transition to remote work; 

n    Comprehensive data and security enhancements to ensure a secure remote digital environment;

n    Engaging an infectious disease specialist to lead multiple informational panel discussions,  

and provide support and guidance to our employees regarding proper COVID-19 protocols; and

n    Enlisting environmental and architectural design specialists to advise on and implement appropriate 

safety measures within our work environment. 

Recognizing the importance of keeping employees engaged during this period we expanded our wellness 
programs and relied on multiple virtual meeting platforms to provide frequent and transparent communication, 
ensuring that all employee questions and concerns were addressed in a timely manner. I look forward to 
welcoming all employees back to our offices as vaccinations become more widely available and we are able to 
safely reopen.

2020 was also a year of great social unrest across our nation as we all grappled with issues related to  

race and systemic inequalities. We have publicly committed to doing our part, have expanded internal 
initiatives via a multi-pronged approach and donated to several organizations dedicated to social justice 
causes. Ambac fosters an inclusive work environment as part of its stated core values and is committed to 
advancing diversity initiatives.

There remains a lot of work to do as we strive  
to ensure an equal playing field for everyone, and  
we will continue to drive those initiatives internally 
while also actively lending our voice and support to 
related causes.

As we adapted to our new environment we 
maintained our focus on our strategic priorities, 
namely, stabilizing our insurance platform, pursuing 
our loss recovery efforts, rationalizing our capital and 
liability structure, improving our operational platform 
and advancing our new business activities. 

For 2020 we reported a net loss of $437 million, 

or $9.47 per diluted share, and Adjusted Loss(1) of 
$378 million, or $8.19 per diluted share. Stockholders’ 
equity at December 31, 2020, was $1.1 billion, or 
$23.57 per share and Adjusted Book Value(1) was $0.9 
billion or $20.05 per share. Our GAAP net loss for the 
year, compared to Adjusted Loss, primarily reflects 
exclusion of amortization expense for our insurance 
intangible asset. 

Our results for the year were impacted by higher 

projected losses in domestic public finance exposures, 
including Puerto Rico, and those exposures directly 
impacted by the economic impact from COVID-19. Net 
investment income was also lower compared to 2019, 
driven by market volatility from the impact of the 
pandemic, a lower allocation toward higher yielding 

Ambac-insured securities and a lower invested asset 
base as a result of derisking transactions executed  
in 2019. 

During the year we continued to focus aggressively 

on existing credits targeted for derisking but also 
expanded our efforts to include COVID impacted credits. 

Notable transactions executed during the  

year included:

n  The refinancing of an international utility 
transaction with net par outstanding of  
$298 million;

n  The refinancing of an international stadium 
transaction with a net par of $217 million;

n  The commutation and refunding of our  

last remaining Chicago GO exposure with  
net par of $171 million;

n  Active negotiation of enhanced credit and 

liquidity protections for key COVID stressed  
exposures, including two of our largest  
insured exposures; and

n  The commutation, refinancing and  

cancellation of several municipal and  
structured credit exposures.

Net par outstanding was reduced by 

approximately $4 billion, or 11%, to $34 billion at  
year-end 2020. Of this, Adversely Classified and

Watch List Credits decreased 13%, excluding the 
COVID impacted credits and by 8% including those 
credits, to $13 billion at December 31, 2020. I am 
extremely pleased with what we accomplished  
notwithstanding the challenging environment. 

As we head into 2021, we have maintained our 
momentum with the successful execution of a large 
quota share reinsurance transaction in January 
involving a portfolio of public finance credits with  
net par outstanding of approximately $823 million  
at December 31, 2020. 
  We will continue to pursue various options to 
sculpt and de-risk our insured portfolio to reduce 
potential tail risk, including additional reinsurance 
transactions, commutations and remediations. We 
believe that such transactions will improve the  
overall quality of our Book and Adjusted Book  
Values and increase optionality for our financial 
guaranty insurance subsidiaries.

During the year we also continued to progress 
our loss recovery efforts, in particular with respect 
to our RMBS litigations. We were nearing trial in our 
main case against Bank of America/Countrywide, 
but the court twice postponed the trial due to 
COVID. Currently we are awaiting a new trial date 
and appealing the dismissal of our fraud claim. The 
timing for the trial will depend on a number of factors, 

including the calendar of a new judge to be assigned 
to the case, the impact of the pandemic on court 
proceedings, and the status of our fraud appeal. We 
continue to be focused on resolving our remaining 
RMBS litigation as quickly and favorably as possible.
  With regards to rationalizing our capital and 
liability structures, we made additional redemptions 
of our outstanding Secured Notes during the year 
totaling $121 million, which brings our total Senior 
Note redemptions to over $500 million, further 
de-levering our balance sheet and lowering annual 
interest costs. 
  We also reduced operating expenses during the 
year by $10 million, reflecting our ongoing focus on 
reducing costs. We will continue our efforts to reduce 
operating expenses and implement cost efficiencies 
in our legacy financial guarantee business. However, 
as we progress our new business initiatives, we do 
expect there will be some related increase in expenses 
on a consolidated basis.

The year culminated with the successful 

advancement of our new business strategy, furthering 
our goal of executing initiatives that we believe 
will drive sustainable long-term shareholder value. 
Our three Pillar new business strategy is focused 
on transforming Ambac Financial Group into a 
financial services holding company with a portfolio of

AMBAC’S NEW BUSINESS  
THREE PILLAR STRATEGY

PILLAR I

>    SPECIALTY PROGRAM PROPERTY  

& CASUALTY INSURANCE

PILLAR II

>    MANAGING GENERAL AGENCY/ 

MANAGING GENERAL UNDERWRITING

PILLAR III

>    INSURANCE SERVICES

synergistic, recurring fee-based businesses that will 
generate strong earnings and allow for the utilization 
of Ambac’s NOLs.

Pillar I is built around Everspan Group, our 
specialty program insurance platform. Everspan 
Group was established during the year following the 
successful redomestication and license expansion of 
our admitted carrier, Everspan Insurance Company 
and the de novo establishment of Everspan Indemnity 
Insurance Company, a surplus lines carrier, each 
domiciled in Arizona. Everspan Group secured an 
“A-” (Excellent) rating from AM Best in February 
2021 and, with capital in excess of $100 million, will 
operate as a Class VIII property & casualty insurance 
platform. Everspan Group will source business from 
multiple channels including Managing General Agents, 
reinsurance brokers, aggregators and other producers. 
Everspan will be differentiated in the P&C specialty 
program market with its ability to retain up to 30% of 
the risk it underwrites, creating a strong alignment of 
interest with its reinsurance partners. Everspan will 
generate revenue from fronting fees, net premiums on 
retained risk, and investment income.

access to (i) high growth businesses with attractive 
rates of return and (ii) the ability to diversify 
revenues. During 2020 we successfully launched 
this component of our strategy with the acquisition 
of 80% of the membership interests of Xchange, a 
specialty accident and health MGU that has delivered 
outstanding growth and profitability, supported by 
major insurers, reinsurers, third party administrators, 
brokers and producers since its inception in 2010. 
Xchange will continue operating under its own brand 
with its existing leadership team. We are excited 
about the future growth prospects for Xchange, which 
include expanding its geographic distribution and 
product diversification and adding new carriers. We 
will continue to build out our MGA/MGU Program 
Manager business through organic growth, additional 
acquisitions and/or partnerships, and investments in 
de-novo platforms.

Pillar III of our strategy targets investments in 

complementary service businesses that will support 
Pillars I and II, including potential investments in 
insurtech platforms and third-party administrators.  

As I reflect on Ambac’s accomplishments over the 

Pillar II of our strategy encompasses fee-based 

managing general agent and managing general 
underwriter businesses. The MGA/MGU Program 
Manager sector is attractive to us because it offers 

past four years since I joined as CEO, I am extremely 
proud of all of our achievements as we continue to 
progress our strategic priorities to generate long-term 
value for our shareholders.

(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 differently. Each of the 
reconciling items is presented in Appendix A to this Annual Report.

(2)  Adversely Classified Credits are either in default or have developed problems that eventually may lead to a default. Watch List Credits are performing credits that demonstrate 

the potential for long-term material adverse development.  

(3)  Par throughout this Annual Report includes capital appreciation bonds (“CABs”) 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.

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

uncertainties  or  factors  that  could  cause  actual  results  to  differ 
materially  are:  (1)  the  highly  speculative  nature  of  AFG’s 
common stock and volatility in the price of AFG’s common stock; 
(2) Ambac's inability to realize the expected recoveries, including 
RMBS  litigation  recoveries,  included  in  its  financial  statements 
which  would  have  a  materially  adverse  effect  on  Ambac 
Assurance  Corporation's  ("AAC")  financial  condition  and  may 
lead to regulatory intervention; (3) failure to recover claims paid 
on  Puerto  Rico  exposures  or  realization  of  losses  in  amounts 
higher  than  expected;  (4)  increases  to  loss  and  loss  expense

managing  general  agency/underwriting  business,  or  related 
businesses;  (7)  potential  of  rehabilitation  proceedings  against 
AAC;  (8) increased fiscal stress experienced by issuers of public 
finance obligations or an increased incidence of Chapter 9 filings 
or  other  restructuring  proceedings  by  public  finance  issuers, 
including an increased risk of loss on revenue bonds of distressed 
public finance issuers due to judicial decisions adverse to revenue 
bond  holders;  (9)  our  inability  to  mitigate  or  remediate  losses,

information,  allocated 

As of and for the year ended December 31, 2020, management 
reviewed 
resources  and 
measured  financial  performance  on  a  consolidated  basis  and 
accordingly the Company had a single reportable segment.  As a 
result of the acquisition of Xchange and the expected launch of 
the  Everspan  Group  platform,  segments  will  be  re-evaluated  in 
2021.

Corporate Strategy:

The  Company's  primary  goal  is  to  maximize  shareholder  value 
through executing the following key strategies:  

its  subsidiaries 

• Active  runoff  of  AAC  and 

through 
transaction terminations, commutations, restructurings, and 
reinsurance  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  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

• Further  expanding  into  specialty  property  and  casualty 
program insurance, managing general agency/underwriting 
and  potentially  other  insurance  and  insurance  related 
businesses  that  will  generate  long-term  shareholder  value 
with  attractive  risk-adjusted  returns  and  meet  other 
preestablished criteria.

DESCRIPTION OF THE BUSINESS

Financial Guarantee Insurance Business:

Ambac's Financial Guarantee strategy is to increase the value of 
its investment in AAC and Ambac UK.  With regards to AAC, 
this  strategy  is  subject  to  the  restrictions  set  forth  in  the 
Settlement Agreement, dated as of June 7, 2010 (the "Settlement 
Agreement"), by and among AAC, Ambac Credit Products LLC 
("ACP"), AFG and certain counterparties to credit default swaps 
with  ACP  that  were  guaranteed  by  AAC,  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 
the  Consolidated  Financial 
to 
and  Business  Description 
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 AAC.  In exercising its approval rights, OCI will act 
for  the  benefit  of  policyholders,  and  will  not  take  into  account 
the  interests  of  AFG.    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. 

the  obligations  guaranteed.  Pursuant 

Financial guarantee insurance policies provide an unconditional 
and  irrevocable  guarantee  which  protects  the  holder  of  a  debt 
obligation  against  non-payment  when  due  of  the  principal  and 
to  such 
interest  on 
guarantees, AAC and Ambac UK make payments if the obligor 
responsible  for  making  payments  fails  to  do  so  when  due.  
Financial guarantee revenues consist mostly of premiums earned 
from insurance contracts, net of reinsurance. Financial guarantee 
expenses consist of: (i) loss and commutation payments; (ii) loss 
adjustment  expenses;  (iii)  interest  expense  on  debt  and  (iv) 
insurance intangible amortization. 

AAC  and  Ambac  UK  have  been  working  toward  reducing 
uncertainties within their insured portfolios such as exposures to 
financially  stressed  municipal  entities  (including  Puerto  Rico) 
and  asset-backed  securities  (including  residential  mortgage-
backed securities ("RMBS") and student loan-backed securities).  
Additionally,  AAC  and  Ambac  UK  are  actively  prosecuting 
legal  claims  (including  RMBS-related  lawsuits  brought  by 
AAC),  managing  their  regulatory  frameworks,  seeking  to 
optimize  capital  allocation  in  a  challenging  environment  that 
includes  long  duration  obligations  and  attempting  to  retain  key 
employees.

Opportunities  for  remediating  losses  on  poorly  performing 
insured transactions also depend on market conditions, including 
the  perception  of  AAC’s  creditworthiness,  the  structure  of  the 
underlying  risk  and  associated  policy  as  well  as  other

counterparty specific factors.  AAC's ability to commute policies 
or purchase certain investments may also be limited by available 
liquidity.

The deterioration of AAC's and Ambac UK's financial condition 
beginning  in  2007  has  prevented  these  companies  from  being 
able to write new financial guaranty business.  Not writing new 
business  has  and  continues  to  negatively  impact  Ambac’s 
operations and financial results. AAC’s ability to pay dividends 
and,  as  a  result,  AFG’s  liquidity,  have  been  significantly 
restricted by the deterioration of AAC’s financial condition and 
by  regulatory,  legal  and  contractual  restrictions.  It  is  highly 
unlikely  that  AAC  will  be  able  to  make  dividend  payments  to 
AFG for the foreseeable future. Refer to "Dividend Restrictions, 
Including Contractual Restrictions" below and Note 9. Insurance 
Regulatory  Restrictions 
the  Consolidated  Financial 
Statements  included  in  Part  II,  Item  8  in  this  Form  10-K,  for 
more information on dividend payment restrictions. 

to 

Interest rate derivative transactions are executed through Ambac 
Financial  Services  (“AFS”),  a  wholly-owned  subsidiary  of 
AAC.  The primary activity of AFS is to partially hedge interest 
rate  risk  in  the  financial  guarantee  insurance  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.  All  AFS  derivative  contracts  containing 
ratings-based  downgrade  triggers  that  could  result  in  collateral 
or  margin  posting  or  a  termination  have  been  triggered.    A 
termination of AFS’s derivatives could result in losses. AFS has 
borrowed  cash  and  securities  from  AAC  to  help  support  its 
collateral and margin posting requirements, previous termination 
payments and other cash needs. 

Credit risks relating to interest rate derivative positions primarily 
relate  to  the  default  of  a  counterparty.  AFS'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. 

customers  or  bank 

• 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.  Interest  rate  derivative  contracts  entered  into 
with  financial  guarantee  customers  are  not  subject  to 
collateral  posting  agreements.  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.

• Credit  risk  associated  with  financial  guarantee  customer 
derivatives  and  credit  derivatives,  is  managed  through  the 
risk  management  processes  described 
the  Risk 
Management Group section below. 

in 

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. 

Segregated Account 

In March 2010, AAC established a segregated account pursuant 
to  Wisconsin  Stat.  §611.24(2)  (the  “Segregated  Account”)  to 
segregate  certain  segments  of  AAC’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  AAC  and  to  refer  to  the  Commissioner  of 
Insurance  for  the  State  of  Wisconsin  as  rehabilitator  of  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.  
AAC, itself, did not enter rehabilitation proceedings. 

rehabilitation  proceedings 

A plan of rehabilitation for the Segregated Account, as amended 
(the  "Segregated  Account  Rehabilitation  Plan"),  became 
effective  on  June  12,  2014.  On  September  25,  2017  the 
Rehabilitator filed a motion in the Rehabilitation Court seeking

the  assets  and/or  obligor  supporting 

Ambac’s  financial  guarantee  insurance  policies  and  credit 
derivative contracts expose the Company to the direct credit risk 
of 
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 ("RMG") 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 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 credit 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. 
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 to 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.

surveillance  activities 

The insured portfolio contains exposures that are correlated and/
include 
or  concentrated.  RMG's 
identifying  these  types  of  exposures  and  identifying  the  risks 
that  would  or  could  trigger  credit  deterioration  across  these 
related  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 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 
privatized  military  housing  portfolio  or  event  risk  such  as 
pandemics (e.g., COVID-19), 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. 

Risk Remediation

Risk  Remediation's  focus  is  on  exposure  reduction,  loss 
mitigation,  avoiding  defaults,  and  restructuring  related  to  the 
insured  portfolio.  In  particular,  this  group  focuses  on  reducing 
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  and  restructuring  focuses  on  the  analysis, 
implementation  and  execution  of  commutation  and  related 
claims  reduction,  defeasance  or  workout  strategies  for  policies 
with potential future claims. Efforts are focused on minimizing 
claims and maximizing  recoveries, typically following an event 
of  default.    The  emphasis  on  reducing  risk  is  centered  on 
reducing exposure on a prioritized basis. 

For  certain  adversely  classified,  survey  list  and  watch  list 
credits,  RMG  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 AAC’s exposure to potential loss. Other 
actions  could  include  working  with  bond  holders  and  other 
economic  stakeholders  to  negotiate,  structure  and  execute 
solutions, such as commutations. In addition, reinsurance is used 
as  a  remediation  tool  to  reduce  exposure  to  certain  targeted 
policies and large concentrations.

Adversely  classified,  survey  list  and  watch  list  credits  are 
tracked closely by RMG 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”).    In  some  cases,  the  RMG  will  engage 
restructuring  or  workout  experts,  attorneys  and/or  other 
consultants  with  appropriate  expertise  in  the  targeted  loss 
mitigation  area 
the 
underlying  contracts  or  collateral,  providing  industry  specific 
advice and/or executing strategies.

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. An example of such efforts 
includes  the  teams  of  professionals  focused  on  the  review  and 
enforcement  of  contractual  representations  and  warranties  
("R&W")  supporting  RMBS  policies.  Members  of  these  cross-
functional  teams  will  often  work  with  external  experts  in  the 
pursuit of risk reduction efforts. 

Credit Risk Management ("CRM")

The CRM function manages the decision process for all material 
matters that affect credit exposures within the insured portfolio. 
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, consents and waivers, 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.  Formal  plans  or  transactions  that  relate  to  risk 
remediation,  loss  mitigation  or  restructuring  may  also  require 
Risk Committee approval. 

Control Rights

In  structured  transactions,  including  certain  structured  public 
finance transactions, AAC 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  is  party  to  and/or  has 
certain  rights  in  documents  supporting  transactions  in  the 
insured  portfolio,  Ambac  frequently  receives  requests  for 
amendments, consents and waivers (“ACWs”).   RMG reviews, 
analyzes  and  processes  all  requests  for  ACWs.  The  decision  to 
approve  or  reject  ACWs  is  based  upon  certain  credit  factors, 
such  as  the  issuer’s  ability  to  repay  the  bonds  and  the  bond’s 
security  features  and  structure.  As  part  of  the  CRM  process, 
members  of  the  RMG  review,  analyze  and  process  all  requests 
for ACWs. 

As a part of the Segregated Account Rehabilitation Proceedings, 
the Rehabilitation Court enjoined certain actions by other parties 
to  preserve  AAC’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 and Adversely Classified Credits

Watch list and adversely classified credits are tracked closely by 
the  appropriate  RMG  teams  and  discussed  as  part  of  the  CRM 
process.  Adversely classified credit meetings include members 
of RMG and other groups within the Company, 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’s  rights  and  potential  remedies,  the  duties  of  all  parties 
involved  and  recommendations  for  corrective  actions.  Ambac 
also meets with relevant parties to the transaction as necessary. 
The review schedule for adversely classified credits is tailored to 
the  remediation  plan  to  track  and  prompt  timely  action  and 
internal  and  external  resourcing.  A  summary  of 
proper 
developments  regarding  adversely  classified  credits  and  credit 
trends  is  also  provided  to  AFG’s,  AAC’s  and  Ambac  UK's 
Board of Directors no less than quarterly.

Ambac assigns internal credit ratings to individual exposures as 
part  of  the  surveillance  process.  These  internal  credit  ratings, 
which  represent  Ambac’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.

Specialty Property & Casualty Program Insurance

The  specialty  property  &  casualty  program  insurance  business 
currently 
Insurance 
includes  admitted  carrier  Everspan 
Company  and  nonadmitted  carrier  Everspan 
Indemnity 
Insurance Company (collectively, “Everspan Group”). Everspan 
Group received a Class VIII, A- Financial Strength Rating from 
A.M. Best Rating Services, Inc. in February 2021, has capital in 
excess  of  $100  million,  and  is  expected  to  begin  writing  new 
property  and  casualty  specialty  insurance  programs  in  the  first 
half  of  2021.    Everspan  Group  is  pursuing  a  sustainable,  long 
term  niche  property/casualty  program  strategy  with  diverse 
classes  of  risks  and  plans  to  source  business  through  diverse 
channels 
including  Managing  General  Agents,  brokers, 
producers and others. Everspan Group's business model will rely 
on  third  party  producers  or  capacity  providers  to  provide  the 
infrastructure  associated  with    policy  administration,  claims 
handling  and  other  insurance  company  services.    Everspan 
Group may retain up to 30% of it gross written premiums and, to 
the  extent  applicable,  will  reinsure  the  remainder  to  reinsurers 
and other providers of risk capital. With its strong capital base, 
Everspan  Group  will  be  differentiated  in  the  specialty  program 
insurance  market  with  its  focus  on  underwriting  results,  risk 
retention, long-term relationships, and the avoidance of channel 
conflicts.  

Everspan  Group  hired  a  management  team  with  a  successful 
track  record  in  specialty  program  insurance  business  and  
relationships with Managing General Agents, brokers, producers 
and third party claims administrators. 

The  specialty  property  &  casualty  program  insurance  business 
will  generate  income  from  (i)  ceding  fees,  by  offering  carrier 
capacity  to  specialty  general  agents  and  other  producers  who 
sell, control and administer books of insurance business that are 
supported  by  third  parties  that  assume  reinsurance  risk  and  (ii) 
net  insurance  underwriting  income  from  any  retained  risk.    Its 
core  expenses  will  include  compensation,  agent  commissions 
and other overhead costs.  

Everspan  Group  will  face  competition  from  long  standing 
program  business  market  participants  such  as  State  National  as 
well  as  more  recent  entrants  such  as  Clear  Blue  Insurance 
Group,  Spinnaker  Insurance  Company,  Trisura  and  Accredited 
Surety  and  Casualty  Company,  Inc.    Everspan  Group  will  also 
compete with new companies that continue to be formed to enter 
the  insurance  markets,  particularly  companies  with  new  or 
"disruptive" technologies or business models. Competition may 
take the form of lower prices, broader coverages, greater product 
flexibility,  higher  coverage  limits,  higher  quality  services  or 
higher ratings by independent rating agencies.  

Few  barriers  exist  to  prevent  insurers  from  entering  target 
markets  within  the  property  and  casualty  industry.  Market 
conditions  and  capital  capacity 
the  degree  of 
competition  at  any  point  in  time.  During  periods  of  excess 
underwriting  capacity,  as  defined  by  the  availability  of  capital, 
competition can result in lower pricing and less favorable policy 
terms  and  conditions  for  insurers.  During  periods  of  reduced 

influence

underwriting  capacity,  pricing  and  policy  terms  and  conditions 
are  generally  more  favorable  for  insurers.  Historically,  the 
performance  of  the  property  and  casualty  insurance  industries 
has  tended  to  fluctuate  in  cyclical  periods  of  price  competition 
and  excess  underwriting  capacity,  followed  by  periods  of  high 
premium  rates  and  shortages  of  underwriting  capacity.  At  any 
given  time,  Everspan  Group's  portfolio  of  insurance  products 
could  experience  varying  combinations  of  these  characteristics. 
This  cyclical  market  pattern  can  be  more  pronounced  in  the 
specialty  insurance  and  reinsurance  markets  in  which  Everspan 
Group competes than the standard insurance market.  

Managing General Agency / Underwriting

On  December  31,  2020,  Ambac  acquired  80%  of 
the 
membership interests of Xchange.  Formed in 2010, Xchange is 
a  specialty-niche,  property  and  casualty  Managing  General 
Underwriter ("MGU") focused on accident and health ("A&H") 
products.    Below  is  a  description  of  its  largest  products  for 
which it provides underwriting services:

Employer  Stop  Loss  ("ESL")  —  provides  protection  for  self-
insured  employers  by  serving  as  a  reimbursement  mechanism 
for catastrophic claims exceeding pre-determined levels.  

Limited Medical ("LM") — designed for those not covered by 
traditional medical programs and sold primarily through affinity 
groups, providing a variety of medically related benefits such as 
hospital or physician visits. 

Short-term Medical ("STM") — sold primarily through affinity 
groups,  providing  comprehensive  medical  coverage  for  short 
periods of time (i.e. less than one year).

Xchange's management team, which retained 20% ownership of 
the  business,  has  significant  longstanding  relationships  with 
carriers,  agents,  policyholders,  affinity  groups  and  reinsurers.  
Xchange  conducts  business 
through  approximately  seven 
insurance carriers and dozens of agents and other distributors.  

is  compensated 

Xchange 
its  services  primarily  by 
for 
commissions  paid  by  insurance  companies  for  underwriting, 
structuring and/or administering polices and, in the case of ESL, 
managing  claims  under  an  agency  agreement.    Commission 
revenues are usually based on a percentage of the premiums paid 
by the insured.  Xchange is also eligible to receive profit sharing 
contingent  commissions  on  certain  programs  (mostly  LM  and 
STM) based on the underwriting results of the policies it writes, 
which  may  cause  some  variability  in  revenue  and  earning 
recognition.      Business  written  by  Xchange  is  generally 
concentrated  in  January  and  July,  which  may  result  is  revenue 
and  earnings  concentrations  in  the  first  and  third  quarters  each 
calendar year.  Xchange's core expenses  include commissions it 
pays  to  its  independent  agents  and  compensation  for  its 
management and staff, which currently total 20 individuals.

The MGU business is highly competitive and a number of firms 
actively  compete  with  Xchange  for  customers  and  insurance 
carrier capacity.  However, the ESL market is increasing in size 
as  large  companies  continue  to  transition  from  fully  insured  to 
self-funded.  As the market size increases, capital is flowing into 
the market, but prices and margins remain stable.  For LM and 
STM, overall market conditions remain stable.  The market as a 
whole  remains  vast,  as  entrepreneurs  and  the  unemployed  seek 

options  for  individual  insurance.  Competition  for  Xchange's 
business  comes 
from  both  direct  carriers  and  other 
intermediaries and, depending on the product, may include Blue 
Cross,  UnitedHealth,  CIGNA,  Aetna,  Tokyo  Marine,  Houston 
Casualty Company, Sun Life, United Health, Axis, Chubb, and 
National General.

including 

(i)  organic  growth, 

Xchange  is  one  component  of  Ambac's  broader  Managing 
General  Agent  ("MGA")/MGU  business  strategy.    Ambac 
expects  to  grow  the  MGA/MGU  business  using  several 
(ii)  additional 
strategies, 
acquisitions  and/or  partnerships,  and  (iii)  establishing  de-novo 
platforms.    Future  expansion  of  the  MGA/MGU  business  is 
expected  to  include  other  property  and  casualty  products  and 
services  in  addition  to  A&H.    Insurance  underwritten  through 
Ambac's  MGA/MGUs  may  utilize  the  Everspan  Group  as  an 
insurance  carrier,  but  will  not  necessarily  be  required  to  do  so, 
depending  on  a  number  of  strategic  and  operational 
considerations.

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  takes  an  enterprise-wide 
approach  to  risk  management  oversight  that  is  designed  to 
support  the  Company's  business  plans  at  a  level  of  risk 
considered by the Board to be reasonable. 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.

protection  and  cybersecurity  that  require  financial  institutions,

personal  and  other  sensitive  information,  and  may  provide  for 
notice of their practices relating to the collection, disclosure and  
processing  of  personal  information,  and  any  related  security

United Kingdom

The  Prudential  Regulatory  Authority  ("PRA")  and  Financial 
Conduct Authority ("FCA") (and their predecessor regulator the 
Financial  Services  Authority  (“FSA”))  exercise  significant 
oversight of Ambac UK.  In 2009, the FSA limited Ambac UK’s 
license  to  undertaking  only  run-off  related  activity.  As  such, 
Ambac UK is authorized to run-off its insurance portfolio in the 
United  Kingdom  and  a  number  of  other  EU  countries.  EU 
legislation allowed Ambac UK to conduct business in EU states 
other  than  the  United  Kingdom  through  a  “passporting” 
arrangement,  which  eliminated  the  necessity  of  additional 
licensing or authorization in those other EU jurisdictions.

On  December  31,  2020,  Ambac  UK's  authorization  to  run-off 
insurance  policies  in  the  EU  through  passporting  arrangements 
ceased.    This  was  a  consequence  of  the  end  of  the  transition

Regulation of change in control

Under applicable Wisconsin and Arizona law, any acquisition of 
control  of  AFG,  or  any  other  direct  or  indirect  acquisition  of 
control of Ambac Assurance or the Everspan Group, requires the 
prior  approval  of  OCI  and  DIFI,  respectively.  “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  or  DIFI,  as 
applicable,  upon  application,  determines  otherwise.  For 
purposes  of  this  test,  AFG  believes  that  a  holder  of  common 
stock  having  the  right  to  cast  10%  or  more  of  the  votes  which 
may  be  cast  by  the  holders  of  all  shares  of  common  stock  of 
AFG  would  be  deemed  to  have  control  of  Ambac  Assurance, 
Everspan Indemnity and Everspan Insurance within the meaning 
of  the  applicable  Wisconsin  and  Arizona  insurance  laws  and 
regulations.  The  United  Kingdom  has  similar  requirements 
applicable in respect  of AFG, as the  ultimate  holding  company 
of Ambac UK.

Dividend Restrictions, Including Contractual Restrictions 

INVESTMENTS AND INVESTMENT POLICY

Due  to  contractual  and  regulatory  restrictions,  AAC  has  been 
unable to pay ordinary dividends to AFG since 2008 and will be 
unable to pay ordinary dividends in 2021. AAC’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  9.  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,  AAC  is  not  expected  to  pay  dividends  to  AFG  for 
the foreseeable future. 

Everspan Indemnity and Everspan Insurance are also subject to 
to  pay  dividends. 
regulatory  restrictions  on 
Everspan  Indemnity  and  Everspan  Insurance  do  not  have 
sufficient  earned  surplus  at  this  time  to  pay  ordinary  dividends 
under the insurance laws and regulations of Arizona.

their  ability 

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  any  transfer  of  value  and/or  assets  from 
Ambac UK to AAC 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 AAC and Ambac UK).  As a result, Ambac UK is not 
expected  to  pay  any  dividends  to  AAC  for  the  foreseeable 
future. 

Pursuant to the Settlement Agreement and the indenture for the 
Tier  2  Notes,  AAC  may  not  make  any  “Restricted 
Payment”  (which  includes  dividends  from  AAC  to  AFG)  in 
excess  of  $5  million  in  the  aggregate  per  annum,  other  than 
Restricted Payments from AAC to AFG in an amount up to $7.5 
million  per  annum  solely  to  pay  operating  expenses  of  AFG. 
Concurrent with making any such Restricted Payment, a pro rata 
amount of AAC's 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 
AAC.

Under the terms of AAC’s AMPS, dividends may not be paid on 
the  common  stock  of  AAC  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  AFG  (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 
that  all 
accumulated  and  unpaid  dividends  have  been  paid  on  the 
AMPS.

As  of  December  31,  2020, 
the  consolidated  non-VIE 
investments  of  Ambac  had  an  aggregate  fair  value  of 
approximately  $3,544  million.  Investments  are  managed  both 
internally  by  experienced  investment  managers  and  externally 
by  investment  management  firms.  All  investments  are  made  in 
accordance with the general objectives, policies, and guidelines 
for investments reviewed or overseen by 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.

As  of  December  31,  2020,  the  AAC  and  Everspan Group  non-
VIE  investment  portfolios  had  an  aggregate  fair  value  of 
approximately  $2,603  million.  The  investment  objective  is  to 
achieve the highest risk-adjusted after-tax return on a diversified 
portfolio  of  fixed  maturity  investments  and  pooled  investment 
funds  consistent  with  the  respective  company'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,  the  investment

In  certain  instances,  AAC  may  exceed  its  established  credit 
rating  or  concentration  limits  with  appropriate  regulatory 
approval.    Changes to AAC’s investment policies are subject to 
approval  by  OCI  pursuant  to  covenants  made  by  AAC  in  the 
Settlement  Agreement,  the  Stipulation  and  Order  and  the 
indenture  for  the  Tier  2  Notes.  See  Note  1.  Background  and

portfolio. 

investment  policy.  Within 

As of December 31, 2020, the non-VIE Ambac UK investment 
portfolio  had  an  aggregate  fair  value  of  approximately  $651 
million.  Ambac  UK’s  investment  policy  is  designed  with  the 
primary objectives of ensuring a reasonable risk-adjusted return 
over  the  remaining  runoff  of  the  insured  portfolio  and  that 
Ambac UK is  able  to  meet its  financial  obligations  as they fall 
due,  in  particular  with  respect  to  policy  holder  claims.  Ambac 
UK’s investment portfolio is primarily diversified fixed maturity 
securities and pooled investment funds.  The 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,  2020,  the  non-VIE  AFG  (parent  company 
only, excluding investments in subsidiaries) investment portfolio 
had an aggregate fair value of approximately $290 million.  The 
primary investment objective is to preserve capital for strategic 
uses  while  maximizing  income.    The  investment  portfolio  is

EMPLOYEES

As  of  December  31,  2020,  Ambac  had  115  employees  in  the 
United  States  and  10  employees  in  the  United  Kingdom.  Our 
2020  voluntary  turnover  rate  was  approximately  3.3%.  Ambac 
considers its employee relations to be satisfactory.

Ambac’s focus has been on identifying and retaining key talent 
through  individual  development  programs  following  skills 
assessments.  Ambac’s  succession  planning  has 
identified 
internal  candidates  that  could  fill  senior  management  and  mid-
level  management  positions  as  the  need  arises.  The  Company 
has established a senior advisory team to work with, and advise, 
senior  management  on  key  initiatives,  and  invested  in  both 
personal  and  professional  growth  programs  to  identify  and 
prepare  executives  for  promotion  within  the  Company.    The 
Company continues to rely on compensation components (such 
as salary, long-term incentive plan awards, deferred cash awards 
and  short-term  incentive  plan  awards)  to  support  employee 
retention  and  discourage  excessive  risk  taking.  The  Company

Risks Related to AFG Common Shares

Investments  in  AFG's  common  stock  are  highly  speculative 
and  the  price  per  share  of  AFG'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  AFG's  common  stock  is  listed  on  the 
New York Stock Exchange ("NYSE"), 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;

• actual  or  perceived  adverse  developments  with  regards  to 
AAC's  residential  mortgage-backed  securities  ("RMBS") 
litigations; 

• changes  in  the  actual  or  perceived  risk  within  our  FG 
to 

insured 
concentrations of credit risk, such as in Puerto Rico;

particularly  with 

portfolio, 

regards 

• changes to regulatory status;

• changes  in  investors’  or  analysts’  valuation  measures  for 

our stock;

• market  perceptions  of  our  success,  or  lack  thereof,  in 

pursuing our business strategy; 

| Ambac Financial Group, Inc.   10   2020 FORM 10-K |

 
 
 
 
 
 
• the 

impact  or  perceived 

impact  of  any  acquisition, 
disposition  or  other  strategic  transaction,  including  entry 
into  a  new  line  of  business,  on  the  value  or  long-term 
prospects of the Company; and

• results and actions of other participants in our industry.

In  addition,  the  price  of  AFG's  shares  may  be  affected  by  the 
additional risks described below, including risks associated with 
AAC’s  ability  to  deliver  value  to  AFG.    Investments  in  AFG'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  AAC,  with  resulting 
adverse consequences to holders of our securities.

Increased  loss  development  in  the  FG  insured  portfolio  or 
significant  losses  or  other  events  resulting  from  litigation, 
including  the  failure  to  achieve  expected  recoveries  from 
existing litigations concerning insured RMBS, may prompt OCI 
to  determine  that  it  is  in  the  best  interests  of  policyholders  to 
initiate  rehabilitation  proceedings  with  respect  to  AAC,  either 
preemptively or in response to any such event.

the  assertion  of  damages  by  counterparties, 

If OCI were to decide to initiate rehabilitation proceedings with 
respect  to  AAC,  adverse  consequences  may  result,  including, 
without  limitation  and  absent  enforceable  protective  injunctive 
relief, 
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  AAC. 
Additionally,  the  rehabilitator  would  assume  control  of  all  of 
AAC’s  assets  and  management  of  AAC.  In  exercising  control, 
the rehabilitator would act for the benefit of policyholders, and 
would not take into account the interests of our security holders, 
which  may  result  in  material  adverse  consequences  for  our 
security holders.

AFG  may  not  be  able  to  realize  value  from  AAC  or  generate 
earnings apart from AAC.

The  value  of  AFG's  common  stock  is  partially  dependent  upon 
realizing  residual value and/or receiving dividends from AAC; 
the  receipt  of  payments  to  be  made  by  AAC  pursuant  to  the 
intercompany  expense  sharing  and  cost  allocation  agreement 
(the  "Cost  Allocation  Agreement");  the  receipt  of  payments  on 
investments  made  in  surplus  notes  issued  by  AAC;    and  the 
receipt  of  payments  on  other  investments.  There  can  be  no 
assurance that AFG will be able to realize residual value and/or 
receive dividends from AAC, which is in run-off.  AFG's ability 
to realize residual value and/or receive dividends from AAC will 
depend  upon,  amongst  other  considerations,  AAC's  ability  to 
satisfy  all  of  its  obligations  that  are  senior  to  AFG's  equity 
interests,  including  obligations  to  policyholders,  holders  of  its 
indebtedness (including surplus notes, the Ambac Note and the 
Tier 2 Notes) and holders of its preferred stock. AAC's ability to 
satisfy  all  of  its  obligations  is  dependent  on  a  number  of 
considerations  including  its  ability  to  achieve  recoveries  and 
mitigate  losses  from  its  insured  portfolio,  which  is  subject  to 
significant  risks  and  uncertainties,  including  as  a  result  of 
varying potential perceptions of the value of AAC’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 AAC will be able to pay AFG any dividends for the 
foreseeable  future.  Furthermore,  the  payments  to  be  made  to 
AFG  under  the  intercompany  Cost  Allocation  Agreement  are 
subject  to,  in  certain  instances,  OCI  approval,  making  the 
amount  and  timing  of  such  payments  uncertain.    Specifically, 
the  Cost  Allocation  Agreement  provides 
that  AAC's 
reimbursement  of certain AFG operating expenses 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.

The value of AFG's common stock also depends upon the ability 
of Ambac to generate earnings apart from AAC. As noted below 
in  Risks  Related  to  Strategic  Plan,  Ambac  is  exploring  further 
expansion 
into  specialty  property  and  casualty  program 
insurance,  managing  general  agent/underwriter,  and  potentially 
other  insurance  and  insurance  related  businesses  that,  among 
other  things,  may  permit  utilization  of  Ambac’s  net  operating 
loss  carry-forwards,  but  there  are  no  assurances  regarding  its 
ability  to  acquire  or  develop  any  material    businesses  or  the 
prospects for any such businesses.

Risks Related to FG 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.

its 

in

to  our  non-derivative 

Loss  reserves  are  established  when  management  has  observed 
insured  credits.  Loss  reserves 
credit  deterioration 
established  with 
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

loss  mitigation 
restructurings  and  other 
strategies;  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.

Additionally,  inherent  in  our  estimates  of  loss  severities  and 
remediation  recoveries  is  the  assumption  that  AAC  or  its 
subsidiaries, as applicable, will retain control rights in respect of 
our  insured  portfolio.  However,  according  to  the  terms  of 
relevant  transaction  documents,  AAC  or  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 
AAC  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.  

Some issuers of public finance obligations insured by AAC 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 AAC 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.  Furthermore,  over  time,  the  consequences  of  poor 
public  policy  decisions  by  state  and  local  governments  or 
increases in tax burdens can impact demographic trends, such as 
out-migration  from  one  state  or  municipality  to  another,  that 
may  negatively  impact  the  creditworthiness  of  related  issuers. 
Some  issuers  of  obligations  insured  by  AAC  have  declared  a 
payment  moratorium,  defaulted  or  filed  for  bankruptcy  or 
similar  debt  adjustment  proceedings,  raising  concerns  about 
their  ultimate  ability  or  willingness  to  service  the  debt  insured 
by AAC and AAC'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, AAC 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  public  health  or  environmental  events,  like  the 
COVID-19  pandemic  or  those  associated  with  hurricanes, 
earthquakes,  wildfires  and  droughts,  that  result  in  material 
disruption  of  economic  activity,  loss  of  human  life  or 
significant  property  damage,  can  have  a  materially  negative 
impact  on  the  financial  performance  of  issuers  of  public 
finance,  structured  finance,  investor  owned  utility,  privatized 
military housing and other obligations insured by AAC. Such 
stresses  could  result  in  liquidity  claims  and/or  permanent 
losses on obligations of those obligations.

The  emergence  of  the  COVID-19  pandemic  and  the  resulting 
containment  measures  have  caused  economic  and  financial 
disruptions  that  have  adversely  affected,  and  are  expected  to 
continue to materially adversely affect, our business and results 
of  operations.  Ambac  insures  the  obligations  of  a  number  of 
issuers  that  have  been,  or  may  in  the  future  be,  substantially 
affected  by  the  economic  effects  of  COVID-19,  such  as 
municipalities  and  securitizations,  including  those  backed  by 
consumer  loans  such  as  mortgages  or  student  loans.    As 
described more fully in Management's Discussion and Analysis 
of Financial Condition and Results of Operations, municipalities 
and  their  authorities,  agencies  and  instrumentalities,  especially 
those  dependent  on  narrow  revenue  streams  flowing  from

continue  to  suffer,  from  severely  depressed  revenues  due  to

and restrictions, and business shutdowns as well as an economic

Furthermore,  securitizations  dependent  on  cash  flows  from

experienced,  and  are  expected  to  continue  to  experience, 
shortfalls in receipts due to borrower nonpayments.  See Part II, 
Item  7  of  this  Form  10-K,  Management's  Discussion  and 
Analysis  of  Financial  Condition  and  Results  of  Operations, 
Executive  Summary,  Financial  Guarantees  in  Force,  Liquidity 
and Capital Resources and Balance Sheet  for further detail.  

The  U.S.  Federal  government  and  other  governments  globally 
have taken certain measures to aid consumers, businesses, state 
and local governments, and the financial markets, but the impact 
of such aid remains unclear. U.S. Federal and State governments 
and  their  agencies  have  also  adopted  policies  or  guidelines  to 
provide  emergency  relief  to  consumers,  such  as  limiting  debt 
requiring  extensions, 
collection  efforts,  encouraging  or 
modifications  or  forbearance  with  respect  to  certain  loans  and 
fees,  and  establishing  foreclosure  and  eviction  moratoriums. 
Several  of  these  policies  or  guidelines  have  been  extended 
beyond  their  initial  terms  and  could  be  expanded  over  time  as 
the economic effects of the pandemic become more well known. 
To the extent such measures cause greater incidences of missed 
mortgage loan, student loan or other debt service payments than 
would have occurred without governmental intervention, Ambac 
may  experience  higher  losses  in  its  insured  portfolio  of  asset-
backed securities.

AAC  also  insures  the  obligations  of  a  number  of  issuers  that 
have  been,  or  may  in  the  future  be,  substantially  affected  by 
environmental or other public health events, including flooding, 
hurricanes,  earthquakes,  wildfires  and  drought.  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 insured by AAC.    

The  ultimate  impact  of  a  catastrophic  public  health  event  like 
COVID-19 or a catastrophic environmental event on issuers and 
their  obligations,  and  the  economy  in  general,  is  by  its  very 
nature uncertain, and  will be determined by a number of factors 
including, but not limited to, the depth and duration of the crisis; 
the  extent  to  which  affected  consumers,  businesses,  municipal 
entities  and  other  debtors  or  sources  of  revenues  recover  from 
depressed  economic  circumstances,  and  the  timelines  for  such 
recoveries; the level  and efficacy of government intervention or 
support  for  municipal  entities,  consumers,  businesses  and  the 
financial markets via emergency relief measures; the availability 
of 
the  availability  of  cost-effective  financing; 
management  of  public  health  crisis  remediation  efforts, 
including 
the  availability,  utilization  and  efficacy  of 
vaccinations;  the  effectiveness  of  other  public  or  private  crisis 
management efforts, mitigation measures or support; and certain 
socio-economic  variables,  such  as  unemployment 
levels. 
Consequently, if issuers affected by such catastrophic events do 
not  have  sufficient  resources  or  financial  flexibility,  receive 
adequate measures of support or realize the appropriate level of 
economic  recovery,  their  ultimate  ability  to  service  the  debt 
insured  by  Ambac  could  be  materially  impaired  and  Ambac 
could suffer material permanent losses.

insurance; 

At  this  time,  there  are  significant  uncertainties  surrounding  the 
ultimate number of claims and the extent of losses Ambac will 
face  as  a  result  of  the  economic  effects  of  the  COVID-19 
pandemic. Actual losses may vary materially from Ambac's loss

and loss expense reserves due to the factors described above and 
the inherent uncertainties in estimating losses given the evolving 
nature  of  the  pandemic  and  its  impact  on  issuers  of  Ambac 
insured  debt  and  the  economy  in  general.    Potential  ultimate 
losses  from  the  economic  consequences  of  the  COVID-19 
pandemic could be material and therefore may have an adverse 
effect on our results of operations and financial condition. 

AAC 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.    AAC  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  AAC  may  not  incur  additional  losses  in  the 
future,  particularly  given  the  uncertainty  related  to  the 
ongoing  Title  III  proceedings  and  the  developing  economic, 
political  and  legal  circumstances  in  Puerto  Rico.  Such  losses 
may  have  a  material  adverse  effect  on  AAC's  results  of 
operation and financial condition.

including 

AAC  has  exposure  to  the  Commonwealth  of  Puerto  Rico  (the 
"Commonwealth"), 
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.  AAC  had 
approximately  $1,070  million  of  net  par  exposure  to  the 
Commonwealth  and  these  instrumentalities  at  December  31, 
the  overall  Puerto  Rico  net  par 
2020.  Components  of 
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  $1,284  million  at 
December 31, 2020.  Total net insured lifetime debt service (net 
par  and  interest)  to  the  Commonwealth  of  Puerto  Rico  and  its 
instrumentalities was approximately $2,540 million at December 
31, 2020. 

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  are  continuing  to  default  on  debt  service 
payments, including payments owed on bonds insured by AAC. 
AAC  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,  changes  in  law  or  the  effects  thereof,  
essential  services  expense,  federal  funding  of  Commonwealth 

needs  as  well  as  interpretation  of  legislation,  legal  documents, 
and updated financial information (when available). 

Substantial  uncertainty  also  exists  with  respect  to  the  ultimate 
outcome for creditors in Puerto Rico due to the Commonwealth 
Plan  of  Adjustment  or  changes  thereto,  as  well  as  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.    AAC  is  involved  in  multiple 
litigations relating to such actions and other issues and may not 
be successful in pursuing claims or protecting its interests. 

Given the numerous uncertainties and risks existing with respect 
to  the  restructuring  process,  outcomes  associated  with  the 
Commonwealth Plan of Adjustment or any changes thereto and 
relevant litigation, no assurance can be given that ultimate debt 
service  discounts  will  not  be  very  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  policy 
proposals  could  be  adopted  and  could  significantly  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"),  the 
Puerto  Rico  Public  Buildings  Authority  ("PBA")  or  any  other 
issuers of Ambac-insured debt that may or may not file for Title 
III protection contemplate discounts to debt service implied by, 
or  even  worse  than,  the  Commonwealth  Fiscal  Plan  (May  27, 
2020) or Ambac receive unfavorable judgments in the litigations 
to  which  it  is  a  party,  Ambac’s  financial  condition  would  be 
materially  adversely  affected.  For  example,  the  amended 
disclosure statement and plan of adjustment ("Amended POA") 
to  restructure  $35  billion  of  debt  and  other  claims  against  the 
Commonwealth  of  Puerto  Rico,  PBA,  and  Employees 
Retirement Systems ("ERS"), as well as more than $50 billion in 
pension  liabilities  that  was  filed  by  the  Federal  Oversight 
Management  Board  for    Puerto  Rico    ("Oversight  Board")  on 
February  28,  2020,  provides  for  an  average  of  3.9%  recoveries 
on claims for non-General Obligation and PBA bonds, including 
revenue  bonds  insured  by  Ambac.  If  the  Amended  POA  was 
confirmed  in  its  current  form,  Ambac's  financial  condition 
would  be  materially  adversely  affected.    It  is  also  possible  that 
economic  or  demographic  outcomes  may  be  as,  or  worse  than, 
forecasted in the Commonwealth Fiscal Plan or under proposals 
or  plans  promulgated  by 
its 
instrumentalities  in  or  in  connection  with  a  Title  III  process  or 
otherwise.  Even  a  negotiated  restructuring  to  which  Ambac 
agrees  as  part  of    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.

Certain  judicial  decisions  related  to  the  Commonwealth  of 
Puerto Rico's PROMESA Title III proceedings may materially 
adversely affect our Public Finance insured portfolio.

On January 13, 2020, the U.S. Supreme Court denied a petition 
for  Writ  of  Certiorari  to  review  decisions  in  March  and  June 
2019  by  the  U.S.  Court  of  Appeals  for  the  First  Circuit  that 
affirmed  decisions  by  the  U.S.  District  Court  overseeing  the 
PROMESA  Title  III  proceedings  for  the  PRHTA,  decisions 
which  found  that  under  Sections  928(a)  and  922(d)  of  the  U.S. 
Bankruptcy  Code,  municipal  issuers  of  revenue  bonds  secured 
by  special  revenues  are  permitted,  but  not  required,  to  apply 
special  revenues  to  pay  debt  service  on  such  revenue  bonds 
during  the  pendency  of  bankruptcy  proceedings  for  such 
municipal  issuers.  The  complainants,  including  AAC,  had 
sought  an  order  compelling  PRHTA,  as  the  debtor,  to  continue 
to  make  debt  service  payments  on  its  revenue  bonds  from 
pledged  special  revenues  during  the  pendency  of  its  Title  III 
case,  but  the  First  Circuit  affirmed  the  District  Court’s 
dismissals  of  the  complaints,  holding  that  it  could  not  compel 
the issuer to make such payments.  The First Circuit's decisions 
challenge  what  had  been  a  commonly  understood  notion  in  the 
municipal 
revenue 
bondholders secured by special revenues (as defined in Chapter 
9  of  the  U.S.  Bankruptcy  Code)  would  continue  to  receive 
payment during a bankruptcy of the municipal issuer.  Although 
the First Circuit’s decisions are binding only on federal district 
and  bankruptcy  courts 
in  Maine,  Massachusetts,  New 
Hampshire,  Puerto  Rico  and  Rhode  Island,  they  introduce 
significant uncertainty into the public finance market, may make 
it  more  difficult  for  municipal  instrumentalities  to  procure 
revenue bond financings in the future and increase the credit risk 
to  bondholders  of  existing  special  revenue  bonds,  particularly 
those from weaker issuers.

that  municipal 

It  is  unclear  how  these  rulings  may  ultimately  impact  Ambac's 
revenue  bond  municipal  exposures,  inclusive  of  Puerto  Rico. 
However,  potential  impacts  could  include  ratings  downgrades, 
decreased  or  more  costly  access  to  capital  markets  for  certain 
issuers  to  refinance  their  insured  debt  or  raise  new  debt,  and 
lower recoveries in a restructuring or bankruptcy. At December 
31, 2020, AAC insured approximately $3,644 million of net par 
of  special  revenue  issuers,  including  $1,235  million  net  par  of 
watch  list  exposure  and  $1,333  million  net  par  of  adversely 
classified  exposure,  $490  million  of  which  was  Puerto  Rico 
exposure.

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  AAC  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  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.  Risks  such  as  these  are  potentially  heightened  by 
Democratic control of the United States Congress and executive 
branch.

In  addition,  there  can  be  no  assurance  that  AAC  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 AAC 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 

| Ambac Financial Group, Inc.   14   2020 FORM 10-K |

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

AAC'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.

AAC is highly leveraged.  AAC’s ability to make payments on 
and/or refinance its debt and to fund its operations will depend 
on its ability to generate substantial operating cash flow and on 
the  performance  of  the  insured  portfolio.      AAC’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, reinsurance  premiums, 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.    There  is  substantial  risk  that  AAC 
may not have the financial resources necessary to pay its debts 
in  full  and  on  time  due  to  risks  associated  with  its  cash  flow, 
expected litigation recoveries and insured portfolio, as discussed 
elsewhere in these Risk Factors.

As  of  December  31,  2020,  AAC  had  approximately  $1,947 
million  of    indebtedness  outstanding  (the  Tier  2  Notes  and  the 
Ambac Note) that are senior to its surplus notes.  AAC had $573 
million principal balance of surplus notes outstanding plus $365 
million principal balance of junior surplus notes outstanding as 
of December 31, 2020.  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 AAC’s ability to service its indebtedness.

If AAC 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  other  factors 
beyond  our  control,  AAC  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.

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 may 
limit the amount of additional indebtedness AAC may incur, we 
may  obtain  waivers  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.

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

In  addition  to  AAC’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 cash 
and  securities  having  an  estimated  fair  market  value  of 
approximately  $178  million.    However,  there  can  be  no 
assurance  that  the  fair  market  value  of  these  securities  will  not 
decrease  significantly.    The  value  of  the  securities  collateral  in 
the  event  of  liquidation  will  depend  on  market  and  economic 
conditions, 
the  availability  of  buyers  and  other  factors. 
Consequently,  when  combined  with  potential  R&W  recoveries, 
liquidating  the  securities  collateral  securing  the  Ambac  Note 
may  not  produce  proceeds  in  an  amount  sufficient  to  pay  all 
amounts due on the Secured Notes.

limitations 

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 
company 
rehabilitation  or  liquidation  proceedings.  In  the  event  of 
rehabilitation,  liquidation,  conservation,  dissolution  or  other 
insolvency  proceeding,  AAC  cannot  assure  holders  that  the 
proceeds from any sale or liquidation of the securities collateral 
will be sufficient to pay any or all of AAC’s obligations  under 
the Ambac Note.  Moreover, the rehabilitator, liquidator or court 
overseeing  such  a  proceeding  may  not  assign  value  to  the 
collateral  with  respect  to  the  Ambac  Note  or  the  Tier  2  Notes, 
including  AAC’s  rights  to  recoveries  in  respect  of  the  RMBS 
litigations,  in  an  amount  sufficient  to  discharge  all  or  a 
substantial portion of AAC's obligations under or with respect to 
the Ambac Note, the Secured Notes and/or the Tier 2 Notes. 

AAC  has  not  made  regular  interest  or  principal  payments  on 
surplus  notes  and  can  not  provide  any  assurance  as  to  when 
payments will be made, if ever.

Payments of interest and principal on surplus notes are subject to 
the prior approval of the OCI.  Since the issuance of the surplus 
notes in 2010, OCI has declined to approve regular payments of 
interest  on  surplus  notes,  although  the  OCI  has  permitted 
exceptional  payments  in  connection  with  (a)  increasing  the 
percentage  of  deferred  policy  payments  of  the  Segregated 
Account of AAC from 25% to 45% in 2014 and (b) a one-time 
payment of approximately six months of interest on the surplus 
notes  outstanding  immediately  after  the  consummation  of  the 
Rehabilitation  Exit  Transactions  in  2018.  AAC  also  did  not 

receive approval from OCI to make payment of the surplus notes 
on their scheduled maturity date of June 7, 2020, and therefore  
the  scheduled  maturity  date  was  extended  until  OCI  grants 
approval  to  make  payment,  in  part  or  in  full.    Interest  will 
accrue,  compounded  on  each  anniversary  of  the  original 
scheduled  maturity  date,  on  any  unpaid  principal  and  interest 
through the actual date of payment, at 5.1% per annum. Holders 
of  surplus  notes  have  no  rights  to  enforce  the  payment  of  the 
principal of, or interest on, surplus notes in the absence of OCI 
approval to pay such amount.  If OCI does not approve regular 
payments on the surplus notes within the next several years, the 
total amount due for surplus notes may exceed AAC's financial 
resources  and holders of surplus  notes  may not  ever  be paid  in 
full. 

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  AAC  and  are 
expressly  subordinated  in  right  of  payment  to  all  of  AAC’s 
existing and future indebtedness 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 
AAC becomes subject to rehabilitation, liquidation, conservation 
or dissolution, holders of AAC’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  AAC’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 AAC.

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;  increases  in  interest  rates  will 
increase 
the  cost  of  servicing  our  debt  reducing  our 
profitability and may affect our ability to make payment on the 
Secured Notes.

The Secured Notes will bear interest at floating rates that could 
rise  significantly,  increasing  AAC’s  interest  expense  and 
reducing  its  cash  flow  and  profitability.  Each  one  percentage 
point  increase  in  interest  rates  would  result  in  a  $6  million 
increase in the annual cash interest payments due on the Secured

other indebtedness.

Ambac’s  estimated  R&W  recovery  may  be  reduced,  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 8. 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,  2020.  As  a  result  of  any  reevaluation,  the 
estimated  amount  of  Ambac’s  R&W  recovery  may  be  adjusted 
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.  A reduction in estimated R&W recoveries may result 
in material changes in Ambac’s financial condition, including its 
capital  and  liquidity.  In  addition,  any  reduction  to  estimated 
R&W recoveries may alter 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  be  reduced, 
materially, 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.

to 

things,  representations  with  respect 

AAC  is  pursuing  claims  in  litigation  with  respect  to  certain 
RMBS transactions that it insured.  These claims are based on, 
among  other 
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,  2020,  we  have  estimated  RMBS  R&W 
subrogation  recoveries  of  $1,725  million  (net  of  reinsurance) 
included in our financial statements. These estimated recoveries 
are  based  on 
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. 

the  contractual  claims  brought 

in 

There  can  be  no  assurance  that  AAC  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 - in the cases being prosecuted by AAC or in 
other  relevant  cases  -  could  delay  or  otherwise  impact  any 
recovery  by  AAC.    Moreover,  rulings  that  may  be  adverse  to 
AAC (in any of its RMBS litigations, as well as in other RMBS 
cases  in  which  it  is  not  a  party)  could  adversely  affect  AAC’s 
ability  to  pursue  its  claims  or  the  amount  or  timing  of  any 
recovery,  or  negatively  alter  settlement  dynamics  with  RMBS 
litigation defendants. Any litigation award or settlement may be 
for  an  amount  less  than  the  amount  necessary  (even  when 
combined  with  other  pledged  collateral)  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  AAC  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 AAC’s outstanding surplus notes, on a timely basis or at all. 
In  the  event  that  AAC  is  unable  to  satisfy  its  obligations  with 
respect to the Secured Notes or Tier 2 Notes, holders will have 
the right to foreclose on any available collateral and to sue AAC 
for failure to make required payments; however, there can be no 
assurance that the sale of collateral will produce proceeds in an 
amount sufficient to pay any or all amounts due on the Secured 
Notes or Tier 2 Notes, as the case may be, or that holders will be 
successful  in  any  litigation  seeking  payments.    Additionally, 
while AAC 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  AAC,  or  at  all.  Depending  on  the  length  of  time 
required to resolve these litigations, either through settlement or 
at  trial,  AAC  could  incur  greater  litigation  expenses  than 
currently projected. If a case is brought to trial, AAC’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 AAC may obtain 
in  litigation.  In  some  instances,  AAC  also  has  claims  against  a 
parent  or  an  acquirer  of  the  counterparty.  However,  AAC  may 
not  be  successful  in  enforcing  its  claims  against  any  successor 
entity.

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

to  rehabilitation, 

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,  2020  would  decrease  from  $1,140  million  to 
$(585) 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 

| Ambac Financial Group, Inc.   17   2020 FORM 10-K |

structures of transactions that AAC 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  AAC's  interests,  the  performance  of  the 
collateral  and  assets  backing  the  obligations  that  AAC  insures, 
and  the  performance  of  servicers  involved  in  securitizations  in 
which  AAC  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  AAC  to  honor  its  financial 
obligations;  the  initiation  of  rehabilitation  proceedings  against 
AAC;  decreased  likelihood  of  AAC  delivering  value  to  AFG, 
through  dividends  or  otherwise;  diminished  business  prospects 
due  to  third  party  concerns  about  our  ability  to  recover  losses; 
and a significant drop in the value of securities issued or insured 
by AFG or AAC, 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 re-underwriting 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. 

If 

these 

recovery. 

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 
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 
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 

competitors, 

meet  or  exceed  its  current  estimates  could  result  in  a  material 
adverse  effect  on  Ambac’s  financial  condition,  including  its 
capital and liquidity. 

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

In pursuing the objective of improving our financial position, we 
are  seeking  to  commute  or  reduce  FG  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.

A significant percentage of our premium revenue is attributable 
to installment premiums.   The amount of installment premiums 
we actually realize 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).  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  AAC  and  Ambac  UK  maintains  a  portion  of  its 
investment  portfolio  in  below  investment  grade  securities, 
equities and/or “alternative assets” with the objective to increase 
risk-adjusted portfolio returns. Investments in below investment 
grade  securities,  equities  and  “alternative  assets”  could  expose 
AAC 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  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

While 
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,  including  those 
relating  to  our  exposures  in  Puerto  Rico,  our  efforts  to  recover 
losses  on  insured  RMBS  through  litigation,  and  other  risks 
described  in  the  Risk  Factors  set  forth  in  this  Item  1A.  
Therefore,  even  following  consummation  of  the  Rehabilitation

surplus, 

The determination of the amount of credit 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  credit  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  
management  has  accurately  assessed  the  level  of  impairments 
taken  in  our  financial  statements.  Furthermore,  additional 
impairments  may  need  to  be  taken  in  the  future  and  historical 
trends  may  not  be  indicative  of  future  impairments.  We  use 
financial  models  and  tools  to  project  impairments.  Differences 
and  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.

prospects.

interest  rate 

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 
rate  consumer 
portion  of 
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.

these  exposures  are 

floating 

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,  issuers  of  debt  which  we  hold  in  our  investment 
portfolio, reinsurers and other contract counterparties (including 
their  financial 
derivative  counterparties)  may  default 
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 public health crises, terrorist acts 
and  natural  disasters);  losses  caused  by  increases  in  municipal 
defaults;  losses  in  respect  of  different,  but  correlated,  credit 
exposures; or other forms of credit risk.

Uncertainties  regarding  the  expected  discontinuance  of  the 
London  Inter-Bank  Offered  Rate  or  any  other  interest  rate 
benchmark could have adverse consequences.

In 2017, the U.K. Financial Conduct Authority (“FCA”), which 
regulates  the  London  Interbank  Offered  Rate  ("LIBOR"), 
announced  that  it  will  no  longer  persuade  or  compel  banks  to 
submit  rates  for  the  calculation  of  LIBOR  after  2021.    On 
November 30, 2020, the ICE Benchmark Administration and the 
FCA  announced  that  most  tenors  of  USD  LIBOR  are  now 
expected  to  be  published  only  through  June  2023.    However, 
Non-USD LIBOR, certain less common tenors of USD-LIBOR 
and  certain  other  indices  which  are  utilized  as  benchmarks  are 
not expected to be published after 2021.  AAC and Ambac UK 
insure  securities,  own  assets,  are  party  to  certain  derivative 
contracts  and  have  issued  debt  and  other  obligations  that 
reference  LIBOR.    While  regulators  and  market  participants 
have  suggested  substitute  benchmark  rates  for  LIBOR,  such  as 
the  Secured  Overnight  Financing  Rate,  the  impact  of  the 
discontinuance and replacement of LIBOR is uncertain.  It is not 
currently  possible  to  know  with  certainty  whether  LIBOR  will 
continue to be viewed as an acceptable benchmark, what rate or 
rates  may  become  accepted  alternatives  to  LIBOR,  or  what  the 
effect  of  any  such  changes  in  views  and  alternatives  may  have 
on the financial markets for LIBOR-linked financial instruments 
for  the  periods  preceding  and  following  LIBOR's  cessation. 
Differences in contractual provisions of certain legacy assets and 
liabilities and other factors, may cause the consequences of the 
discontinuance of LIBOR to vary by instrument. Legislation has 
been introduced in both the UK and the United States, including 

| Ambac Financial Group, Inc.   19   2020 FORM 10-K |

at  the  New  York  State  level,  to  address  issues  with  respect  to 
legacy LIBOR-linked assets and liabilities, however it is unclear 
whether these initiatives will be passed and if so, whether they 
will fully address the issues associated with legacy transactions.   
As  a  result,  the  value  of  our  assets,  derivatives  and  liabilities; 
costs to operate our business; and the losses associated with our 
insured  portfolio  may  be  affected  in  a  way  that  may  ultimately 
materially  adversely  impact  Ambac’s  results  of  operations  and 
financial condition.  In addition, Ambac may experience adverse 
tax  and  accounting  impacts,  system  and  model  disruption,  and 
increased  liquidity  demands  in  connection  with  the  transition 
away  from  LIBOR 
that  may  have  adverse  operational 
consequences  resulting  in  further  adverse  impacts  on  Ambac’s 
results  of  operations  and  financial  condition.  Ambac  continues 
to  actively  monitor  developments  surrounding  the  transition 
from LIBOR-based indices and evaluate the potential impact.  In 
addition  to  reviewing  several  hundred  transactions  involving 
various  LIBOR-based  indices,  Ambac  has  made,  or  is  in  the 
process  of  making,  adjustments  to  its  reporting  and  analytical 
infrastructures to facilitate the transition from LIBOR.

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. 

AAC  is  defending  or  otherwise  involved  in  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 17. Commitments 
and  Contingencies  to  the  Consolidated  Financial  Statements 
included in Part II, Item 8 in this Form 10-K for information on 
these various proceedings.

It  is  not  possible  to  predict  whether  additional  suits  involving 
AFG,  AAC  or  one  or  more  other  subsidiaries  will  be  filed  or 
for 
whether  additional 
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,  AAC  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  AAC  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 
administrative 
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,  increased  costs, 
distractions  to  management,  strained  working  relationships  or 
otherwise.  Such  effects  would  also  increase  the  risk  that  OCI 
would seek to initiate rehabilitation proceedings against AAC.

Impairment  of  the  intangible  and  goodwill  assets,  which 
resulted  from  the  acquisition  of  Xchange,  could  adversely 
affect our results of operations.  

In  connection  with  Ambac’s  acquisition  of  80%  of  the 
membership  interests  of  Xchange,  Ambac  recorded  the  fair 
value  of  identifiable  intangible  assets  (primarily  related  to 
distribution  relationships)  and  goodwill.    The  intangible  assets 
will be amortized over their useful lives (weighted average of 14 
years).  The Company will test intangible assets for impairment 
if  certain  events  occur  or  circumstances  change  indicating  that 
the  carrying  amount  of  the  intangible  asset  may  not  be 
recoverable. Goodwill reflects the excess purchase consideration 
over  net  assets  acquired  and  will  be  tested  for  impairment 
annually or whenever events occur or circumstances change that 
impairment.  Intangible  asset  and  goodwill 
may 
impairments  are  driven  by  a  variety  of  factors,  which  could 
include,  among  other  things,  declining  future  cash  flows  of  the 
acquired business as addressed in other risk factors related to the 
Managing General Underwriting Business. Any intangible asset 
or  goodwill  impairment  could  adversely  affect  the  Company's 
operating results and financial condition.

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

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

identifiable  information  of  individuals.  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,  or  personally  identifiable  information  of 
individuals,  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  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

Actions of the PRA and FCA could reduce the value of Ambac 
UK  realizable  by  AAC,  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.  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 when considering whether to provide 
any  such  approval.    Accordingly,  determinations  made  by  the 
PRA  and  FCA,  in  their  capacity  as  Ambac  UK’s  regulators, 
could  potentially  result  in  adverse  consequences  for  our 
securityholders and also reduce the value realizable by AAC for 
Ambac UK.

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 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 
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

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  AAC  may  be 
characterized  as  equity  of  AAC  and  as  a  result,  AAC  may  no 
longer  be  a  member  of 
tax 
consolidated group of which AFG is the common parent.

the  U.S.  federal 

income 

It  is  possible  that  certain  surplus  notes  or  other  obligations  of 
AAC  may  be  characterized  as  equity  of  AAC  for  U.S.  federal 
income  tax  purposes.  If  such  surplus  notes  or  other  obligations 
are characterized as equity of AAC 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  AAC,  AAC  may  no  longer  be  characterized  as  an 
includable  corporation  that  is  affiliated  with  AFG.  As  a  result, 
AAC would no longer be characterized as a member of the U.S. 
federal  income  tax  consolidated  group  of  which  AFG  is  the 
common  parent  (the  “Ambac  Consolidated  Group”)  and  AAC 
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  AAC  as  the  new  common  parent 
and  AAC’s  affiliated  subsidiaries  (the  “AAC  Consolidated  Tax 
Group”).

To  the  extent  AAC  is  no  longer  a  member  of  the  Ambac 
Consolidated  Group,  AAC’s  net  operating  loss  carry-forwards 
("NOLs") (and certain other available tax attributes of AAC and 
the  other  members  of  the  AAC  Consolidated  Tax  Group)  may 
no  longer  be  available  for  use  by  the  AAC  Consolidated  Tax 
Group  or  any  of  the  remaining  members  of  the  AAC 
Consolidated  Tax  Group  to  reduce  the  U.S.  federal  income  tax 
liabilities of the AAC Consolidated Tax Group. AFG, AAC and 
their  affiliates  entered  into  a  tax  sharing  agreement  that  would 
require AFG to make certain tax elections that could mitigate the 
loss  of  NOLs  and  other  tax  attributes  resulting  from  a 
deconsolidation  of  AAC  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 
transactions 
occurring between members of the Ambac Consolidated Group 
and members of the AAC Consolidated Tax Group.

to 

If  surplus  notes  or  other  obligations  are  characterized  as 
equity of AAC, the AAC 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  AAC  for  U.S.  federal  income  tax 
purposes.  Such  characterization  could  result  in  an  “ownership 
change” of AAC for purposes of Section 382 of the Tax Code. If 

such an ownership change were to occur, the value and amount 
of  the  AAC  NOLs  would  be  substantially  impaired,  increasing 
the  U.S.  federal  income  tax  liability  of  AAC  and  materially 
reducing  the  value  of  AAC’s  stock  owned  by  AFG  and  the 
potential for future dividend payments from AAC to AFG.

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  AAC.  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 AAC 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 planning to further develop and expand the Specialty 
Property  and  Casualty  Program  Insurance  business  and  the 
Managing General Agency/Underwriting business, which may 
permit  utilization  of  Ambac’s  net  operating  loss  carry-
forwards;  however,  such  plans  may  not  be  realized,  or  if 
realized, may not create value and may negatively impact our 
financial results.

Ambac is planning to further develop and expand the Specialty 
Property  and  Casualty  Program  Insurance  Business  and  the 
Managing  General  Agency/Underwriting  business  which  may, 
amongst other things, permit utilization of its net operating loss 
carry-forwards.  Such plans may involve additional acquisitions 
of  assets  or  existing  businesses  and  the  development  of 
businesses  through  new  or  existing  subsidiaries.  It  is  not 
possible at this time to fully predict the future prospects or other 
characteristics  of  such  businesses.  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 certain business 
opportunities  may  be  unsuccessful  or  require  significant 
financial or other resources, which could have a negative impact 
on  our  operating  results  and  financial  condition.  No  assurance 
can be given that Ambac will be able to successfully execute its 
plans  for  new  business,  generate  any  earnings  from  new 
businesses or be able to successfully integrate any such business 
into our current operating structure.

Moreover,  Ambac’s  ability  to  enter  into  new  businesses  apart 
from  AAC  is  subject  to  some  doubt,  given  the  financial 
condition of AAC, counterparty or rating agency concerns about 
our ability to mitigate insured portfolio losses or recover losses 
in litigation, 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  AAC  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 circumstances or financial condition or in the political, 
economic  and/or  legal  environment  occur,  there  can  be  no 
assurance that all or any part of such strategy and/or initiatives 
will  not  be  abandoned  or  amended  to  take  account  of  such 
changes.  Any  such  adjustment  or  abandonment  may  have  an 
adverse effect on our securities.

Risks Related to the Managing General Underwriting 
Business

Xchange  derives  a  significant  portion  of  its  commission 
revenues  from  a  limited  number  of  insurance  companies,  the 
loss of any of which could result in lower commissions or loss 
of business production.

from 

For the year ended December 31, 2020, a majority of Xchange’s 
total  commissions  was  derived 
insurance  policies 
underwritten  by  a  limited  number  of  insurance  companies.  
Should one or more of these insurance companies terminate its 
arrangements with Xchange or otherwise decrease the number of 
insurance  policies  underwritten  for  it,  Xchange  may  lose 
significant  commission  revenues  or  lose  significant  business 
production  while

Xchange’s  business,  results  of  operation,  financial  condition 
and  liquidity  may  be  materially  adversely  affected  by  certain 
potential claims, regulatory actions or proceedings.

Xchange  is  subject  to  various  potential  claims,  regulatory 
actions  and  other  proceedings,  including  those  relating  to 
alleged  errors  and  omissions  in  connection  with  the  placement 
or servicing of insurance and/or the provision of services in the 
ordinary course of business, of which we cannot, and likely will 
not  be  able  to,  predict  the  outcome  with  certainty.  Because 
Xchange  often  assists  customers  with  matters 
involving 
substantial  amounts  of  money,  including  the  placement  of 
insurance and the handling of related claims that customers may 
assert, errors and omissions, claims against it may arise alleging 
potential liability for all or part of the amounts in question. Also, 
the  failure  of  an  insurer  with  whom  Xchange  places  business 
could  result  in  errors  and  omissions  claims  against  it  by  its 
customers,  which  could  adversely  affect  Ambac’s  results  of 
operations  and  financial  condition.  Claimants  may  seek  large 
damage  awards,  and  these  claims  may  involve  potentially 
significant  legal  costs  and  damages.    In  addition,  regardless  of 
monetary  costs,  these  matters  could  have  a  material  adverse 
effect  on  Xchange's  reputation  and  cause  harm  to  its  carrier, 
customer  or  employee  relationships,  or  divert  personnel  and 
management resources.

Xchange’s  current  market  share  may  decrease  because  of 
disintermediation  within  the  insurance  industry,  including 
increased  competition  from  insurance  companies,  technology 
companies  and  the  financial  services  industry,  as  well  as  the 
shift away from traditional insurance markets.

The MGU business is highly competitive and Xchange actively 
competes  with  numerous  firms  for  customers  and  insurance

companies  or  have  a  significant  presence  in  niche  insurance 
markets  that  may  give  them  an  advantage  over  it.  Other 
competitive  concerns  may  include  the  quality  of  Xchange’s 
products and services, its pricing and the entrance of technology 
companies  into  the  MGU  business.  A  number  of  insurance 
companies are engaged in the direct sale of insurance and do not 
pay  commissions  to  agents  and  brokers.  In  addition,  and  to  the 
extent  that  banks,  securities  firms,  private  equity  funds,  and 
insurance  companies  affiliate,  the  financial  services  industry 
may  experience  further  consolidation,  and  Xchange  therefore

be  certain  that  such  alternative  markets  will  provide  the  same

historically 
demonstrated  an  ability  to  adjust  its  products  to  major  changes 
in  the  healthcare  industry,  given  its  focus  on  A&H  products,  
Xchange would likely be adversely impacted by such a material 
change  in  the  U.S.  healthcare  system  particularly  if  private 
health insurance is eliminated, materially limited, or is rendered 
noncompetitive.    Material  adverse  developments  to  Xchange's 
business  would  have  a  negative  impact  on  Ambac's  financial 
condition and results of operations which could be material.

Xchange’s  business  and  results  of  operation  and  financial 
condition may be adversely affected by conditions that result in 
reduced insurer capacity.

Xchange’s  results  of  operations  depend  on  the  continued 
capacity  of  insurance  carriers  to  underwrite  risk  and  provide 
coverage, which depends in turn on those insurance companies’ 
ability to procure reinsurance. Capacity could also be reduced by 
insurance companies failing or withdrawing from writing certain 
coverages that Xchange offers to its customers. Xchange has no 
control  over  these  matters.  To  the  extent  that  reinsurance 
becomes  less  widely  available  or  significantly  more  expensive, 
Xchange  may  not  be  able  to  procure  the  amount  or  types  of 
coverage that its customers desire and the coverage Xchange is 
able  to  procure  for  its  customers  may  be  more  expensive  or 
limited.

Variations  in  Xchange’s  commissions  that  result  from  the 
timing  of  policy  renewals  and  the  net  effect  of  new  and  lost 
business  production  may  have  unexpected  effects  on  our 
results of operation.

Xchange’s  commission  income  can  vary  quarterly  or  annually 
due  to  the  timing  of  policy  renewals  and  the  net  effect  of  new 
and  lost  business  production.  Xchange  does  not  control  the 
factors  that  cause  these  variations.  Specifically,  customers’ 
demand  for  insurance  products  can  influence  the  timing  of

renewals,  new  business  and  lost  business  (which  includes 
policies that are not renewed), and cancellations.  Quarterly and 
annual  fluctuations  in  revenues  based  upon  increases  and 
decreases  associated  with  the  timing  of  new  business,  policy 
renewals  and  payments  from 
insurance  companies  may 
adversely  affect  our  financial  condition,  results  of  operations 
and cash flows. Profit-sharing contingent commissions are paid 
by  insurance  companies  based  upon  the  profitability  of  the 
business  placed  with  such  companies.  In  the  past  these 
commissions  have  accounted  for  a  material  amount  of 
Xchange’s  total  commissions  and  fees.  Due  to,  among  other 
things,  the  inherent  uncertainty  of  loss  in  Xchange’s  industry 
and  changes  in  underwriting  criteria  by  insurance  companies, 
there  will  be  a  level  of  uncertainty  related  to  the  payment  of 
profit-sharing contingent commissions.

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

AAC and Subsidiaries

A  key  strategy  for  Ambac  is  to  increase  the  value  of  its 
investment  in  AAC  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

internal 

Investment  portfolios  are  subject 
investment 
guidelines, as well as limits on types and quality of investments 
imposed  by  insurance  laws  and  regulations.  The  investment 
portfolios  of  AAC  and  Ambac  UK  also  hold  fixed  maturity 
securities  and  various  pooled  investment  funds.    Refer  to  Note 
11.  Investments  to  the  Consolidated  Financial  Statements, 
included in Part II, Item 8 in this Form 10-K for further details 
of  fixed  maturity  investments  by  asset  category  and  pooled 
investment funds by investment type.

At  December  31,  2020,  Ambac  and  its  subsidiaries  owned 
$621  million  of  distressed  Ambac-insured  bonds,  including 
significant  concentrations  of  insured  Puerto  Rico  and  RMBS 
bonds, and excluding Ambac's holdings of secured notes issued 
by  Ambac  LSNI.  Subject  to  internal  and  regulatory  guidelines, 
market conditions and other constraints, Ambac may continue to 
opportunistically purchase or sell Ambac-insured securities. 

Liability and Insured Exposure Management

AAC's Risk Management Group focuses on the implementation 
and  execution  of  risk  reduction,  defeasance  and  loss  recovery 
strategies.    Analysts  evaluate  the  estimated  timing  and  severity 
of projected policy claims as well as the potential impact of loss 
mitigation  or  remediation  strategies  in  order  to  target  and 
prioritize  policies,  or  portions 
thereof,  for  commutation, 
reinsurance,  refinancing,  restructuring  or  other  risk  reduction 
strategies.  For  targeted  policies,  analysts  will  engage  with

• Partial commutations of $32 million of adversely classified 

credits over the course of 2020.

AAC's RMG had additional successes in the first quarter of 2021 
as follows:

• In  January  2021,  AAC  completed  the  purchase  of  quota 
share  reinsurance  on  a  portfolio  of  public  finance  credits 
with  net  par  outstanding  of  approximately  $823  million  at 
December 31, 2020.  Par ceded included general obligation 
($347  million), 
tax-backed  revenue  ($234 
million), higher education ($161 million) and transportation 
($81  million)  and  included  $160  million  of  watch  list  and 
adversely classified credits.

lease  and 

• In  February  2021,  AAC's  exposure  to  an  adversely 
classified stadium transaction was reduced by $540 million 
through  the  combination  of  a  refinancing  and  quota  share 
reinsurance.

The  following  table  provides  a  comparison  of  total,  adversely 
classified  ("ACC")  and  watch  list  credit  net  par  outstanding  in 
the  insured portfolio  at December  31, 2020 and  2019.  Net par

time  of  issuance  of  the  insurance  policy  as  opposed  to  the 
current accreted value of the bonds.

The decrease in total net par outstanding resulted from active de-
risking  initiatives,  including  the  transactions  noted  above,  as 
well  as  scheduled  maturities,  amortizations,  refundings  and 
calls.  This  overall  decrease  in  total  net  par  outstanding  was 
partially offset by the weakening of the US Dollar compared to 
the British Pound and the Euro.

The increase in ACC exposures is primarily due to the addition 
of credits impacted by COVID-19 (including $982 million of net 
par outstanding from the Watch List category), such as hotel tax, 
insured 
stadium,  convention  center  and  public  house

various  monetary  policy,  fiscal  stimulus  measures  and  other 
actions have helped to moderate the economic impact.    

The  decrease  in  Watch  List  net  par  outstanding  resulted  from 
active  de-risking  initiatives  (including  the  transactions  noted 
above),  downgrades  to  ACC  due  to  COVID-19,  and  scheduled 
maturities, amortizations, refundings and calls.

In  addition,  as  a  result  of  the  economic  impacts  from  the 
COVID-19  pandemic,  $2,397  million  of  net  par  outstanding  in 
sectors  such  as  mass  transit,  toll  roads,  and  private  higher 
education,  among  others,  have  been  added  to  the  Survey  List.  
The Survey List is a categorization for enhanced monitoring of 
currently performing credits. 

We also continue to experience stress in our exposure to Puerto 
Rico that consists of several different issuing entities (all below 
investment  grade).    Each  issuing  entity  has  its  own  credit  risk 
profile  attributable  to  discreet  revenue  sources,  direct  general 
obligation  pledges  and  general  obligation  guarantees.    Refer  to

COVID-19

In  March  2020,  the  outbreak  of  COVID-19,  caused  by  a  novel 
strain of the coronavirus, was recognized as a pandemic by the 
World  Health  Organization,  and  the  outbreak  is  widespread 
globally,  including  in  the  markets  in  which  we  operate.  The 
COVID-19  outbreak  had,  and  continues  to  have,  a  notable 
impact  on  general  economic  conditions,  including  but  not 
limited  to  higher  unemployment;  volatility  in  the  capital 
markets;  closure  or  severe  curtailment  of  the  operations  and, 
hence,  revenues,  of  many  businesses  and  public  and  private 
enterprises to which we are directly or indirectly exposed, such 
as hotels, restaurants, sports and entertainment facilities, airports 
and  other  transportation  facilities,  and  retail  establishments, 
mostly  due  to  social  distancing  guidelines,  travel  bans  and 
restrictions, and business restrictions and shutdowns. 

In the U.S., significant monetary policy actions, fiscal stimulus 
measures and other relief measures have helped to moderate the 
economic  impact  of  COVID-19.  These  measures  include 
monetary  policy  decisions,  such  as  quantitative  easing, 
providing  liquidity  to  financial  institutions,  providing  liquidity 
to  credit  markets,  the  Paycheck  Protection  Program  Lending 
Facility  and  the  Main  Street  Business  Lending  Program; 
Congressional actions, such as the $2.4 trillion Coronavirus Aid, 
Relief and Economic Security ("CARES") Act, the $483 billion 
Paycheck Protection Program And Health Care Enactment Act, 
the $190 billion Families First Coronavirus Response Act, and, 
most 
the  $920  billion  2021  Consolidated 
Appropriations Act, which, among other things, provides direct 
payments  to  households,  support  for  small  businesses,  renter 
assistance and funding for transport, airlines, education and state 
and  local  governments.  In  addition,  housing  measures,  such  as 
forbearance  on  mortgages  and  suspension  of  foreclosures  and 
evictions,  and  various  executive  orders  have  helped  to  provide 
relief. Outside of the US, and in the United Kingdom and Italy 
in  particular,  where  Ambac  has  insured  portfolio  exposure,

Nonetheless,  the  U.S.  and  many  large  global  economies 
contracted on a full year basis in 2020. In the U.S., the trajectory 
and  sustainability  of  the  economic  recovery  experienced  in  the 
second half of 2020 is uncertain due to, among other things, the 
magnitude  of 
further 
losses,  uncertainty 
regarding 
government  support  measures, 
the  acceleration  of  new 
COVID-19  cases  and  the  uncertainty  related  to  the  timing  of  a 
critical  mass  of  COVID-19  vaccines  being  provided  to  the 
broader population. For the Ambac insured portfolio, credit risk 
remains  elevated  due  to  the  historical  and  future  economic  and 
financial impact related to the COVID-19 crisis.

COVID-19  has  also  impacted  Ambac's  operating  environment.   
Ambac has implemented a COVID-19 response plan designed to 
ensure  the  safety  of  our  staff  and  business  continuity.  Our 
employees  transitioned  to  working  remotely  in  March  2020 
while maintaining full operational capabilities.  Since July 2020, 
Ambac  opened  certain  of  its  offices  to  allow  a  portion  of  the 
workforce  to  safely  return  on  a  voluntary  basis.    We  have  not 
experienced  and  do  not  anticipate  incurring  material  net 
incremental  operating  expenditures  to  maintain  the  current 
operating  environment.  Although  many  of  Ambac's  critical 
third-party  service  providers  are  operating  with  employees 
working  remotely,  we  have  not  presently 
identified  or 
experienced  any  limitations  or  operational  constraints  with 
respect  to  services  provided.    Ambac  does  not  believe  that  our 
current  operating  environment  has  resulted  in  a  significant 
change  to  our  disclosure  controls  or  internal  controls  over 
financial reporting. 

COVID-19  has  adversely  impacted  Ambac's  financial  position 
and  results  of  operations  as  credit  risk  in  the  insured  and 
investment  portfolios  has  increased.    In  the  insured  portfolio, 
municipal,  mortgage-backed,  student  loan  and  other  asset 
securitization exposures could be materially adversely impacted, 
and  as  a  result,  with  the  exception  of  the  mortgage-backed 
sector, we increased loss reserves across each of these and other 
sectors  during  the  year  ended  December  31,  2020.  In  the 
mortgage-backed  sector,  significantly  lower  interest  rates  have 
increased  excess  spread  levels  and  largely  offset  the  impact  of 
higher  mortgage  delinquencies  and  projected  losses  resulting 
from the COVID-19 pandemic. We are continuously evaluating 
and  updating  our  view  of  the  macro  economic  environment  as 
well as our specific credit view of each of our insured exposures 
considering the significant uncertainties brought upon us by the 
COVID-19  pandemic.  The  overall  financial 
impact  from 
COVID-19 has been and will be a function of (i) the willingness 
and ability of issuers of insured debt and other counterparties to 
pay  their  obligations  when  due;  (ii)  the  impact  of  changes  to 
interest  rates  on  policy  and  derivative  payments;  and  (iii)  the 
performance of the investment portfolio. 

• Ambac’s insurance policies will be drawn in the event that 
the issuers of insured obligations do not make payments on 
their  obligations  when  due.    As  a  result  of  the  COVID-19 
related  economic  impact  on  issuers  and  markets  where 
Ambac provides financial guarantees; including  lower tax, 
project,  and  business 
in 
forbearances  or  delinquencies  on  mortgage  and  student 
loan  payments,  we  have  increased  our  loss  reserves  and 

revenues  and

may  further  increase  them  in  the  future  depending  on  the 
duration  and  severity  of  the  crisis.    The  crisis  may  also 
impair  certain  issuers'  ability  to  pay  premiums  owed  to 
Ambac;  however,  we  believe  such  issuers  currently  have 
the  ability  to  continue  to  pay  such  premiums  timely,  but 
this is subject to change.  

• Ambac has exposure to reinsurance counterparties for their 
portions  of  future  claim  payments.    Ambac  has  reinsured 
approximately  13.3%  of  its  gross  par  outstanding  to  four 
reinsurance  counterparties.  Each  of  these  reinsurance 
counterparties  is  experienced  in  the  business  of  reinsuring 
and/or  writing  financial  guaranty  insurance.  All  have 
current  ratings  of  A+  (by  S&P)  or  better  and  have 
collateralization  or  replacement  triggers  upon  downgrade. 
Ambac actively monitors each of these reinsurance entities 
and  currently  believes  they  have  the  ability  to  perform 
under  their  respective  reinsurance  policies,  but  this  is 
subject to change. 

• Ambac is exposed to the risk that contractual counterparties 
(including those under our RMBS litigations and derivative 
counterparties)  may  default  in  their  financial  obligations, 
whether  as  the  result  of  insolvency,  lack  of  liquidity, 
operational  failure,  fraud  or  other  reasons.  At  present, 
Ambac has no concerns about the ability of our contractual 
counterparties,  which  include  certain  regulated  exchanges 
in  the  case  of  interest  rate  swaps  and  futures,  to  perform 
under their contracts, but this is subject to change.

• Asset prices declined substantially during the first quarter, 
particularly  in  directly  affected  industries  such  as  tourism, 
airlines, 
and 
manufacturing.  While  Ambac  does  not  have  significant 
investments  in  these  asset  classes,  we  did  experience  a 
negative  total  return  for  the  investment  portfolio  of 
approximately (4.4)% during the three month period ending 
March 31, 2020.  We evaluated the investment portfolio at 
March 31, 2020, and in subsequent quarters,  and  have not 
recognized credit impairments.  Over the last three quarters 
of  2020,  we  have  repositioned  the  investment  portfolio  to 
manage  credit  risk  while  improving  risk  adjusted  return, 
including  redeploying  capital  into  new  asset  categories.  
Ambac  recognized  a  total  return  for  the  investment 
portfolio  of  approximately  4.1%  for  the  year  ended 
December 31, 2020  

Given  the  economic  uncertainties  associated  with  the  duration 
and effects of the COVID-19 pandemic, it is impossible to fully 
predict all of its consequences and, as a result, it is possible that 
our  future  operating  results  and  financial  condition  may  be 
materially adversely affected.  Refer to "Financial Guarantees In 
Force," 
"Balance  Sheet 
Commentary" for further financial details on the current impact 
from COVID-19.

"Results  of  Operations"  and 

With  regard  to  Ambac's  new  business  strategic  objective,  we 
continue to evaluate opportunities in a disciplined manner.  Our 
evaluation process has been revised to incorporate consideration 
of  the  impact  of  COVID-19  on  new  business  prospects  as  well 
as Ambac's existing business and operations.

LIBOR Sunset

In July 2017, the Financial Conduct Authority, the authority that 
regulates  LIBOR,  announced  its  intention  to  stop  compelling 
banks  to  submit  rates  for  the  calculation  of  LIBOR  after  2021. 
The Alternative Reference Rates Committee (‘ARRC’), a group 
of private-market participants convened by the Federal Reserve 
Board  and  the  Federal  Reserve  Bank  of  New  York  to  help 
ensure  a  successful  transition  from  U.S.  dollar  LIBOR  (‘USD-
LIBOR’)  to  a  more  robust  reference  rate,  proposed  that  the 
Secured Overnight Financing Rate (‘SOFR’) represents the best 
alternative  to  USD-LIBOR  for  use  in  derivatives  and  other 
financial  contracts  that  are  currently  indexed  to  USD-LIBOR. 
ARRC  has  proposed  a  transition  plan  with  specific  steps  and 
timelines  designed  to  encourage  the  adoption  of  SOFR  and 
guide the transition to SOFR from USD-LIBOR. The Finanical 
Conduct Authority in the United Kingdom and other regulatory 
bodies  have  issued  statements  encouraging  cessation  of  new 
transactions referencing USD LIBOR after December 31, 2021, 
while  supporting  extension  of  the  publication  of  major  USD-
LIBOR tenors to mid-2023 to allow additional legacy contracts 
to  mature  on  their  existing  terms.    Organizations  are  currently 
working on industry-wide and company-specific transition plans 
related to derivatives and cash markets exposed to USD-LIBOR. 
Similar  efforts  are  underway  to  identify  suitable  replacement 
reference  rates  for  LIBOR  in  other  major  currencies.    As  of 
December 31, 2020, the Company has exposure to LIBOR in the 
following areas: (i) the financial guarantee insured portfolio, (ii) 
the Ambac Note included in long-term debt, (iii) certain invested 
assets and interest rate derivatives.   

Ambac has reviewed its financial guarantee portfolio to identify 
insured  transactions  that  it  believes  may  be  vulnerable  to  the 
transition  from  LIBOR.  The  review  focused  on  insured  issues 
that are scheduled or projected to have an outstanding principal

transition  steps  outlined  by  the  International  Swaps  and 
Derivatives  Association,  Inc.  ("ISDA"). 
  Our  non-cleared 
interest rate swaps either have offsetting LIBOR exposure with a 
single  counterparty  that  serves  as  calculation  agent  responsible 
for rate changes or have Ambac as the calculation agent.  

Given  the  uncertainty  of  the  ultimate  timing  of  the  LIBOR 
sunset,  as  well  as  the    lack  of  clarity  on  decisions  that  parties 
responsible  for  calculating  interest  rates  will  make  and  the 
reaction  of  impacted  parties  as  well  as  the  unknown  level  of 
interest  rates  when  the  change  occurs,  the  Company  cannot  at 
this time predict the impact of the discontinuance of LIBOR, if it 
occurs,  on  every    obligation  the  Company  guarantees  or  on  its 
instruments.  For  more

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, political events, market 
conditions, industry trends and other information. 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 
these 
those  determinations.  Additional 
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. 

information  about 

Valuation  of  Losses  and  Loss  Expense  Reserves  (including 
Subrogation Recoverables)

The loss and loss expense reserves and subrogation recoverable 
assets  (collectively  defined  as  "loss  reserves")  discussed  in  this 
section relate only to Ambac’s non-derivative insurance policies 
issued  to  beneficiaries,  including  unconsolidated  VIEs.  A  loss 
reserve  is  recorded  on  the  balance  sheet  on  a  policy-by-policy 
basis based upon the present value ("PV") of expected net claim 
cash outflows or expected net recovery cash inflows, discounted 
at risk-free rates. The estimate for future net cash flows consider 
the  likelihood  of  all  possible  outcomes  that  may  occur  from 
missed  principal  and/or  interest  payments  on  the  insured 
obligation. This estimate also considers future recoveries related 
to  breaches  of  contractual  representations  and  warranties  by 
RMBS  transaction  sponsors,  remediation  strategies,  excess 
spread  and  other  contractual  or  subrogation-related  cash  flows. 
Ambac’s  approach  to  resolving  disputes  involving  contractual 
breaches  by  transaction  sponsors  or  other  third  parties  has 
included negotiations and/or pursuing litigation. Ambac does not 
estimate  recoveries  for  litigations  where  its  sole  claim  is  for 
fraudulent  inducement,  since  any  remedies  under  such  claims 
would be non-contractual. 

The  evaluation  process  for  expected  future  net  cash  flows  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;  our  ability  to  execute  workout 
strategies  and  commutations;  economic  and  market  conditions; 
and  management's  judgments  with  regards  to  the  current 
performance  and  future  developments  within 
insured 
portfolio.  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 

the 

prosperity. Reinsurance contracts mitigate our loss reserves 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.

The table below indicates the gross par outstanding and gross loss reserves (including loss expenses) related to policies in Ambac’s loss and 
loss expense reserves at December 31, 2020 and 2019:

2019, respectively.

See  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  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  claim  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 
scenarios  or  probabilities  will  not  deviate  materially  from 
ultimate outcomes.  

In  some  cases,  such  as  RMBS  and  student  loans,  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.  With 
respect  to  RMBS,  a  component  of  our  loss  reserve  estimate 
includes  subrogation  recoveries  related  to  securitized  loans  in 
such  transactions  that  breached  certain  representations  and 
warranties  ("R&W").    In  other  cases,  such  as  many  public 
finance  exposures  including  our  Puerto  Rico  exposures,  we 
consider the issuers’ overall ability and willingness to pay, as it 
relates to the existing fiscal, economic, legal, restructuring and/
or political framework relevant to a particular exposure or group 

of exposures.  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.    There  is  no 
certainty  our  assumptions  as  to  scenarios  or  probabilities  will 
not be subject to material changes as developments occur.

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, restructure or commute the policy in whole or in part. 
The  remediation  scenarios  and  the  related  probabilities  of 
occurrence  vary  by  policy  depending  on  ongoing  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. 

Valuation of Certain Financial Instruments

The  Fair  Value  Measurement  Topic  of  the  ASC  requires 
financial  instruments  to  be  classified  within  a  three-level  fair 
the  financial 
value  hierarchy.  The  fair  value  hierarchy, 
instruments classified within each level, our valuation methods,

the  Consolidated  Financial 
to 
Statements included in Part II, Item 8 in this Form 10-K.  

The  level  of  judgment  in  estimating  fair  value  is  largely 
dependent  on  the  amount  of  observable  market  information 
available  to  fair  value  a  financial  instrument,  which  is  also 
determinative  of  where  the  financial  instrument  is  classified  in 
the  fair  value  hierarchy.    Level  3  instruments  are  valued  using 
models which use one or more significant inputs or value drivers 
that are unobservable and therefore require significant judgment. 
Level 3 financial instruments which are material include certain 
invested  assets,  uncollateralized 
interest  rate  swaps  and 
investments and loan receivables of consolidated VIEs.  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  investments  and  loan  receivables  of 
consolidated  VIEs  incorporate  estimates  of  Ambac's  financial 
guarantee  cash  flows,  including  future  premiums  and  losses. 
Such  cash

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  and  Risk  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

judgment 

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 
is 
taxing  authorities.  Significant 
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"). More specifically, deferred 
tax  assets  represent  a  future  tax  benefit  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.  

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 tax losses; cumulative pre-tax 
losses  in  recent  years;  uncertainty  regarding  timing  and 
magnitude  of  RMBS  R&W  litigation  recoveries;  and  no  new 
financial guarantee business.   

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 above-described 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 such risks 
and  uncertainties  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  to  the 
Consolidated Financial Statements, included in Part II, Item 8 in 
this  Form  10-K  for  additional  information  on  the  Company's 
deferred income taxes.

FINANCIAL GUARANTEES IN FORCE

The following table provides a breakdown of guaranteed net par 
outstanding  by  market  sector  at  December  31,  2020  and  2019.  
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  in 
accordance  with 
the  ASC, 
Consolidation.  Guaranteed  net  par  outstanding  excludes  the 
exposures  of  policies  that  insure  bonds  which  have  been 
refunded  or  pre-refunded  and  the  policy  that  insures  the  notes 
issued  by  Ambac  LSNI  as  defined  in  Note  1.  Background  and

Internal  credit  ratings  are  provided  solely  to  indicate  the  underlying  credit  quality  of  guaranteed  obligations  based  on  the  view  of  Ambac.  In  cases 
where Ambac 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  credit  ratings  are  subject  to  revision  at  any  time  and  do  not  constitute  investment  advice.  BIG

(4)

In  February  2021,  the  net  par  outstanding  for  this  transaction  was  reduced  to  zero  through  the  combination  of  a  refinancing  and  quota  share 
reinsurance.

Net par related to the top ten exposures increased $79 million from December 31, 2019.  Exposures are impacted by changes in foreign 
exchange  rates,  certain  indexation  rates  and  scheduled  and  unscheduled  paydowns.    The  increase  from  2019  was  primarily  related  to 
changes  in  foreign  exchange  rates  partially  offset  by  scheduled  paydowns.    The  concentration  of  net  par  amongst  the  top  ten  (as  a 
percentage  of  net  par  outstanding)  has  increased  to  23%  from  20%  at  December  31,  2019.    Certain  credits  within  the  top  ten  have  had 
Ambac rating downgrades since December 31, 2019, primarily related to the impact of COVID-19, including Mitchells & Butlers Finance 
plc, New Jersey Transportation Trust Fund Authority and Mets Queens Baseball Stadium Project.  Aspire Defence Finance plc's rating at 
December 31, 2020, improved since December 31, 2019.  The remaining insured portfolio of financial guarantees has an average net par 
outstanding  of  $32  million  per  single  risk,  with  insured  exposures  ranging  up  to  $534  million  and  a  median  net  par  outstanding  of  $5 
million.

Given that Ambac has not written any new insurance policies since 2008, the risk exists that the insured portfolio becomes increasingly 
concentrated to large and/or below investment grade exposures.

COVID-19

COVID-19  and  the  public  health  responses  by  the  US  federal  
and state governments at the onset of the pandemic resulted in a 
shut  down  for  several  months  of  significant  portions  of  the  US 
economy,  including  areas  that  Ambac's  insured  obligors  rely 
upon  to  generate  the  revenues  and  cash  flows  necessary  to 
service  debts  we  insure.  Governments  outside  the  US,  in 
markets  in  which  Ambac  operates,  also  implemented  similar 
measures to the US.  Ambac undertook a detailed analysis of the 
potential  impact  of  the  closure  of  certain  portions  of  the  US 
economy  and  certain  other  economies,  including  the  UK,  Italy, 
and  Australia,  to  assess  the  impact  of  the  resulting  global 
economic  contraction  on 
insured  financial  guarantee 
its 
portfolio.  The economic contraction and the subsequent but still 
uncertain  recovery;  actions  such  as  monetary  policy  and  fiscal 
stimulus,  including  the  CARES  Act  in  the  US  that  was  signed 

into law on March 27, 2020, and other fiscal stimulus programs; 
and  our  insured  obligors'  financial  flexibility  and  ability  to 
mitigate  the  operational  and  economic  impact  of  the  recession 
will determine the ultimate impact to Ambac's insured portfolio.  

CARES Act and Other Relief Measures

The  $2.4  trillion  Coronavirus  Aid,  Relief,  and  Economic 
Security Act ("CARES Act") provides relief and stimulus funds 
for American consumers, businesses and industries impacted by 
COVID-19.  Other  Congressional  measures,  such  as  the  $483 
billion  Paycheck  Protection  Program  and  Health  Care 
Enhancement  Act  ("PPE  &  HCE  Act")  and  the  recent  $920 
billion  Consolidated  2021  Appropriations  Act  have  provided 
additional measures to moderate the impact of COVID-19 on the 
economy. 

| Ambac Financial Group, Inc.   34   2020 FORM 10-K |

 
 
 
 
 
 
 
 
 
The  CARES  Act  together  with  the  PPP  &  HCE  Act  and  the 
2021  Consolidated  Appropriations  Act  have  several  measures 
that impacted US municipalities and other borrowers, including 
consumers,  such  as  mortgage  and  student  loan  borrowers, 
represented in our insured portfolio, including:

• A  program  for  direct  lending,  loans,  loan  guarantees  and 
investments 
and 
municipalities,  including  to  passenger  airlines  and  cargo 
airlines;

businesses, 

eligible 

states 

to 

• Programs for small business loans;

• Business tax breaks, including payroll tax deferral;

• Allocations of direct aid to state and local governments to 
reimburse them for the costs of dealing with COVID-19;

• The Public Health and Social Services Fund for distribution 

of grants to healthcare providers and hospitals;

• Grants for transit agencies;

• Grants for airport authorities; 

• Funding  for  transport,  airlines,  education,  state  and  local 

governments, health, vaccines, nutrition; 

• Emergency jobless benefits; 

• Renter assistance; and

• Direct  payments  to  households  and  for  unemployment 

insurance.

Despite  the  above  provisions,  which  are  designed  to  help 
mitigate  the  economic  impact  of  the  COVID-19  pandemic 
generally, the CARES Act contains certain provisions that may 
adversely affect Ambac.

In  March  2020,  the  CARES  Act  temporarily  suspended 
payments  on  all  student  loans  held  by  the  Department  of 
Education  through  September  30,  2020.  The  moratorium  on 
payments  has  twice  been  extended  by  executive  order  and  is 
now set to expire on September 30, 2021.  Although the CARES 
Act provision did not include the private student loans owned by 
special  purpose  entities  that  have  their  securitized  obligations 
guaranteed by AAC, we have incorporated into our loss reserves 
analysis  assumptions  related  to  increased  delinquencies  for 
borrowers with private student loans who often also have federal 
student loans and have elected not to pay altogether. Despite the 
assumed  increase  in  delinquencies  and  losses  related  to  this 
phenomena  as  well  as  the  general  deterioration  in  consumer 
credit  related  to  the  economic  downturn,  AAC  does  not 
anticipate making substantial claim payments on insured student 
loan  transactions  for  several  years  due  to  the  structures 
governing the insured bonds.

Additionally,  the  federal  government  has  provided  temporary 
relief  measures  to  which  servicers  of  mortgage  loans  must 
adhere.  The Federal Housing Administration ("FHA") of the US 
Department of Housing and Urban Development and the Federal 
Housing  Finance  Agency  ("FHFA")  are  providing  temporary 
relief  measures  that  require  mortgage  loan  servicers  to  offer 
relief to borrowers who suffer hardship as a result of COVID-19. 
The  relief  measures  include  moratoriums  on  foreclosures  and 
evictions as well as the expansion of forbearance and subsequent 
repayment options.  Such servicers are generally applying these 
guidelines to non-FHFA loans, including those loans owned by 
special  purpose  entities  that  have  their  securitized  obligations 

guaranteed  by  AAC.  Moreover,  several  State  agencies  have 
issued  similar  guidance  to  mortgage  loan  servicers  concerning 
loan forbearances and other relief for borrowers. Depending on 
the trajectory and strength of the economic recovery, there may 
still  be  pressure  to  extend  the  duration  of  forbearances  and 
subsequently  to  offer  generous  repayment  plans.    Forbearances 
increased  sharply  across  the  AAC's  insured  first  lien  RMBS 
obligations  during  the  second  quarter  of  2020  and  early  in  the 
third quarter of 2020, but then dropped later in the third quarter 
of  2020  through  the  end  of  the  year,  albeit  to  still  elevated 
levels.  The  ultimate  impact  of  forbearances  and  other  relief 
measures,  such  as  foreclosure  and  eviction  moratoriums,  on 
AAC's insured RMBS obligations are still unclear. However, we 
have assumed that such measures, as well as the residual impact 
of  the  global  recession,  will  have  an  adverse  impact  on  our 
insured RMBS transactions.  Consequently, we have anticipated 
that we will experience an increase in claim payments for certain 
of our insured RMBS obligations.  However, we also anticipate 
that  the  significant  decline  in  interest  rates  experienced  during 
2020 will likely generate additional excess spread recoveries on 
insured RMBS obligations that will mostly compensate for such 
adverse effects.

In  the  UK  all  non-essential  leisure,  food  and  retail  operations, 
including public houses were closed from March 20, 2020, as a 
consequence  of  the  COVID-19  pandemic.  Premises  were 
allowed to gradually reopen from June 1, 2020, such that by July 
4,  2020,  the  majority  of  outlets  were  permitted  to  reopen.  The 
UK  Government  introduced  a  number  of  measures  to  mitigate 
the  impact  of  these  enforced  closures  including  rebating 
employers  80%  of  staff  salaries  (up  to  a  £2,500  per  month  per 
employee cap), tax deferrals, sales tax reductions, business loan 
schemes  and  property  tax  relief.    On  January  5,  2021,  the  UK 
Government reimposed the closure of non-essential leisure food 
and  retail  operations  until  February  15,  2021,  with    a  gradual 
opening  of  venues on regional basis thereafter.   The mitigating 
measures  noted  above  will  continue  through  this  period  before 
then being slowly withdrawn by April 30, 2021.

While  Ambac  expects  the  foregoing  measures  to  help  mitigate 
economic damage and aid the functioning of the capital markets, 
Ambac's  exposure  to  credit  risk  as  a  result  of  the  economic 
fallout from the COVID-19 pandemic remains elevated, and we 
could  experience  material  losses  that  would  adversely  impact 
our future results of operations and financial condition. 

Insured Portfolio

A deep recession during the first half of 2020 was followed by a 
moderate  recovery  in  the  second  half  of  2020  that  still  left  the 
U.S.  with  an  overall  contraction  in  GDP  for  the  full  year. 
Economic growth for 2021, while expected to be positive, is also 
expected to be tempered by the continued uncertainty related to 
the  elevated  infection  rate  of  COVID-19  in  the  U.S.  and  the 
uncertain  timing  related  to  achieving  a  critical  mass  of 
COVID-19 vaccinations across the populace. Recovery to 2019 
levels  of  economic  output  are  not  expected  until  late  2021  or 
early  2022.  Consequently,  we  expect  pressure  will  remain  on 
U.S.  states  and  local  governments  which  are  currently  facing 
significant budget strains as tax and other revenues have faltered 
as a result of COVID-19 related shutdowns, job losses and travel 
restrictions.  In  addition  states  may  need  to  cut  aid  to  local 
municipalities  that  are  also  under  pressure  from  lost  revenues.

Monetary  policy  and  federal  stimulus  through  the  CARES  Act 
and other programs has benefited and is expected to continue to 
benefit  in  the  overall  economic  recovery  and  more  specifically 
provide some relief to state and local governments, including to 
issuers  of  municipal  debt  insured  by  Ambac,  although  the 
sufficiency of such benefits remains uncertain.   

As part of the detailed analysis of the insured portfolio, we have 
identified  certain  Public  Finance  sectors 
that  are  most 
susceptible  to  potential  claims  or  impairments  as  a  result  of  a 
prolonged  or  uneven  recovery  from  the  COVID-19  crisis.  Our 
near-term  concerns  are  concentrated  on  exposures  substantially 
reliant on narrow, economically sensitive revenue streams.  The 
ability  of  issuers  of  these  obligations  to  pay  is  expected  to  be 
stressed although several issuers expressed a willingness to use 
their  balance  sheets  to  support  their  obligations  and  avoid 
defaults in the near-term.  Ambac's insured par outstanding, net 
of  reinsurance  ("NPO"),  to  these  Public  Finance  sectors  are  as

The  RMBS  and  student  loan  insured  portfolios  are  expected  to 
be adversely impacted by the previously mentioned forbearances 
and  the  overall  state  of  the  U.S.  economy  which  contracted  in 
2020,  and  where  unemployment  is  still  elevated  and  job 
participation rates are depressed. Expected to offset such impact 
for  RMBS  exposures  is  the  benefit  to  excess  spread  within  the 
securitization structures as a result of the significant reduction in 
interest  rates,  which  will  result  in  higher  recoveries.    Ambac

At  this  time,  there  are  significant  uncertainties  surrounding  the 
ultimate number of claims and scope of damage resulting from 
this  pandemic.  Actual  losses  from  these  events  may  vary 
materially  from  Ambac's  loss  and  loss  expense  reserves  due  to 
several  factors,  including  the  inherent  uncertainties  in  making 
such  determinations  and  the  evolving  nature  of  this  pandemic.  
Potential  losses  from  the  economic  consequences  of  the 
COVID-19 pandemic could be material and therefore may have 
a  material  adverse  effect  on  our  results  of  operations  and 
financial condition.  

U.S. Public Finance Insured Portfolio 

Ambac’s  portfolio  of  U.S.  public  finance  exposures  is  $15,497 
million, representing 46% of Ambac’s net par outstanding as of 
December  31,  2020,  and  a  12%  reduction  from  the  amount 
outstanding  at  December  31,  2019.  This  reduction  in  exposure 
was  due  to  additional  reinsurance  acquired,  restructuring  and 
related  commutation  transactions,  scheduled  paydowns,  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  7.  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, competitive position, industry and socioeconomic 
trends,  government  programs  and  other  factors.  Examples  of 

| Ambac Financial Group, Inc.   36   2020 FORM 10-K |

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
these  types  of  transactions  include  not-for-profit  hospitals, 
universities, associations and charities.

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  $5,575  million  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,  construction 
completion,  environmental  remediation,  utility  and  other 
operating  costs  and  housing  management.  Ambac's 
exposure  to  privatized  military  housing  debt  is  a  growing 
concentration given the long-dated  maturity profile of the 
exposure  relative  to  faster  run-off  of    other  parts  of 
Ambac's  insured  portfolio.  As  of  December  31,  2020, 
privatized military housing represented approximately 16% 
of net par outstanding.

Puerto Rico

its 

Ambac has exposure to the Commonwealth of Puerto Rico (the 
"Commonwealth")  and 
instrumentalities  across  several 
different issuing entities with total net par exposure of $1,070 as 
of  December  31,  2020.  Each  has  its  own  credit  risk  profile 
attributable  to,  as  applicable,  discrete  revenue  sources,  direct 
general obligation pledges and/or general obligation guarantees.

COVID-19  

At this time, it remains very difficult to predict what the shape 
and  timing  of  the  post  COVID-19  recovery  will  be  for  the 
Commonwealth of Puerto Rico, not least because the depth and 
length of COVID-19's impact is still uncertain. The island does 
not appear to be insulated from the fiscal and economic impact 
COVID-19 has had on U.S. municipalities on the mainland. Net 
general  fund  revenue  collected  from  July-November  2020 
totaled  $4.01  billion,  down  about  $210  million  from  the  $4.22 
billion  collected  during  the  same  period  in  2019,  according  to 
the  Puerto  Rico  Treasury  Department's  tax  collection  reports 
released  in  January  2021.  Sales  and  use,  corporate  income  and 

personal  income  tax  collections  have  all  been  adversely 
impacted to varying degrees by the pandemic. It is unclear if this 
cumulative  underperformance  will  continue,  what  this  implies 
for  the  Commonwealth’s  ability  to  pay  debt  service,  and  what 
lasting  effects  COVID-19  will  have  on  the  economic  and 
financial profile of Puerto Rico.

Over  the  longer-term,  Puerto  Rico's  recovery  profile  will  be 
impacted  by  a  wide  range  of  factors  as  well  as  financial 
considerations including, but not limited to:

• the fiscal and monetary policies of the federal government 

which will shape the trajectory of the U.S. economy; 

• the  speed  and  efficacy  of  targeted  federal  aid  packages  to 
(1) help Puerto Rico address the negative economic effects 
of  the  pandemic  and  (2)  rebuild  better  and  more  resilient 
infrastructure post-Hurricanes Irma and Maria in 2017 and 
earthquakes in 2020;

• the  receptivity,  availability,  pace  and  effectiveness  of 

vaccinations for COVID-19;

• changes to supplemental Medicaid funding relief and other 

federal transfer payments; and

• the  willingness  and  ability  of 

implement  much  needed

fiscal  and 

government 
structural reforms.

Commonwealth Fiscal Plan

the  Oversight  Board  certified 

the 
On  May  27,  2020, 
Commonwealth  Fiscal  Plan,  which  purports  to  incorporate  the 
impact  of  COVID-19  on  the  Commonwealth  economy,  and 
projects diminished growth, budget surplus, and debt capacity as 
compared  to  previous  versions  of  the  Commonwealth  Fiscal 
Plan.  The  Commonwealth  Fiscal  Plan  will  significantly  inform 
the  Commonwealth  Plan  of  Adjustment,  and  the  diminished 
economic performance described in the new Fiscal Plan implies 
worse outcomes than had been previously disclosed for creditors 
under the Commonwealth's Plan of Adjustment. 

According to a letter sent January 19, 2021, from the Oversight 
Board's Executive Director, Natalie Jaresko, to Governor Pedro 
Pierluisi  and  legislative  leaders,  the  Oversight  Board  is  aiming 
to certify an updated Commonwealth Fiscal Plan reflecting new 
information  regarding  the  Commonwealth’s  macroeconomic 
environment and government revenues and expenditures, as well 
as  the  impact  of  expenses  from  the  anticipated  amended  
Commonwealth  Plan  of  Adjustment.  The  letter  also  establishes 
the  timeline  for  the  annual  fiscal  plan  revision  process,  which 
would  conclude  with  the  Oversight  Board  certification  of  the 
Commonwealth Fiscal Plan by April 23, 2021.

No  assurances  can  be  given  that  Ambac's  financial  condition 
will not suffer a materially negative impact as an ultimate result 
of  the  Commonwealth  Fiscal  Plan,  the  Commonwealth  Plan  of 
Adjustment,  or  any  future  changes  or  revisions

Commonwealth Plan of Adjustment 

On February 9, 2020, the Oversight Board announced it reached 
an  agreement  in  principle  on  a  plan  support  agreement  (the 
the 
"Amended  PSA")  with  certain  creditors  supporting

restructuring of the Commonwealth's General Obligation ("GO") 
and  Public  Building  Authority  ("PBA")  debt.  On  February  28, 
2020,  the  Oversight  Board  filed  an  Amended  POA  and  an 
amended Disclosure Statement to restructure approximately $35 
billion  of  debt  and  other  claims  against  the  Commonwealth  of 
Puerto  Rico,  PBA,  Employees  Retirement  System  (ERS),  and 
other  issuers  as  well  as  more  than  $50  billion  in  pension 
liabilities.  If  confirmed,  the  Amended  POA  would  reduce 
Commonwealth  debt  and  other  claims  from  $35  billion  to  less 
than  $11  billion,  a  70%  haircut  and  would  also  reduce  the 
Commonwealth’s  annual  debt  service  by  56%.  Treatment  for 
pension  claims  would  include  a  reduction  in  pension  payments 
by  as  much  as  8.5%  for  retirees  who  currently  receive  at  least 
$1,200  a  month,  such  that  approximately  75%  of  current  and

years.  The  Amended  POA 

In  light  of  COVID-19  and  its  impact,  and  potential  future 
impact,  on  the  Commonwealth,  the  Oversight  Board  and  the 
parties to the Amended PSA began negotiating revisions to the 
Amended PSA without terminating that agreement. Information 
released  publicly  regarding  these  negotiations  indicated  that 
proposals  considered  during  the  course  of  such  negotiations 
implied  recoveries  related  to  certain  revenue  bonds  insured  by 
AAC below 3.9%. 

On October 28, 2020, the Court ordered the Oversight Board to 
file, by February 10, 2021, either (i) an informative motion with 
a  term  sheet  disclosing  the  economic  and  structural  terms  and 
features  of  a  proposed  amended  Commonwealth  Plan  of 
Adjustment, or (ii) the proposed amended Commonwealth Plan 
of  Adjustment  itself,  together  with  a  proposed  timeline  for 
disclosure statement and confirmation hearings. On February 16, 
2021, the Court entered an order granting the Oversight Board’s 
motion  to  extend  the  court’s  deadline  to  file  a  Commonwealth 
Plan  of  Adjustment  or  comprehensive  term  sheet  to  March  8, 
2021. The Oversight Board's motion disclosed that the Oversight 
Board reached an agreement in principle regarding the terms of 
a  new  plan  support  agreement  (the  “Second  Amended  PSA”) 
with certain holders of GO Bond Claims and/or CW Guarantee 
Bond Claims (each as defined in the Second Amended PSA) and 
holders  of  PBA  Bond  Claims  (as  defined  in  the  Second 
Amended  PSA).  The  motion  also  indicated  that  the  requested 
extension  of  the  deadline  to  March  8,  2021,  will  allow  the 
Oversight  Board  to  schedule  and  conduct  additional  mediation 
sessions  with  parties  in  interest  to  increase  support  for  the 
forthcoming Commonwealth Plan of Adjustment.

On February 22, 2021, the  Oversight Board, as representative of 
the  Commonwealth  of  Puerto  Rico,  PBA,  and  the  Employee 
Retirement System of the Government of the Commonwealth of 
Puerto  Rico  publicly  disclosed  the  Second  Amended  PSA. 
Assured Guaranty Corp. and Assured Guaranty Municipal Corp. 
("Assured"),  Syncora  Guarantee  Inc.,  and  National  Public 
Finance  Guarantee  Corporation  ("National")  have  conditionally 

agreed  to  the  Second  Amended  PSA.  In  addition,  by  a  Joint 
Notice  of  Termination,  dated  February  22,  2021,  the  Amended 
PSA, dated as of February 9, 2020, was terminated and is of no 
further  force  or  effect.  On  February  23,  2021,  the  Oversight 
Board  announced  that  the  Second  Amended  PSA  had  the 
support  of  70%  of  all  GO  Bond  and  PBA  Bond  claims.  In  the 
Second  Amended  PSA,  approximately  $18.8  billion  of  the  GO 
and  GO-guaranteed  liabilities  will  be  reduced  to  approximately 
$7.4  billion,  newly  issued  securities  will  be  GO-only  with  no 
inclusion of the COFINA junior lien bonds contemplated within 
the February 2020 Amended POA, and creditors will accept part 
of their recovery consideration in the form of a contingent value 
instrument  (“CVI”)  that  pays  out  if  a  portion  of  the  island’s 
Sales and Use Tax outperforms the projections in the Oversight 
Board’s Certified Fiscal Plan. 

The  Government  of  the  Commonwealth  of  Puerto  Rico  and 
Ambac  Assurance  are  not  currently  parties  to  the  Second 
Amended PSA. Further, the Second Amended PSA provides that 
Assured  and  National  may  terminate  their  agreement  to  the 
Second Amended PSA on or prior to March 31, 2021; until that 
date,  Assured  and  National  are  permitted  to  continue  litigation 
against the Oversight Board with respect to certain revenue bond 
exposures.    If  Assured  and  National  do  not  terminate  their 
agreement  by  March  31,  2021,  the  Second  Amended  PSA 
requires  that  Assured  and  National  take  no  further  action  with 
respect to such revenue bond-related litigation.

Given  that  the  Oversight  Board  has  stated  publicly  that  it  is 
further  amending  the  Amended  POA,  including  to  reflect  the 
terms  of  the  Second  Amended  PSA,  it  is  not  yet  clear  how  the 
Commonwealth Plan of Adjustment will be modified or how the 
final  adjustments  will  impact  revenues  available  to  the  Puerto 
Rico  instrumentalities  addressed  in  the  Commonwealth  Plan  of 
Adjustment  or 
the 
Commonwealth  by  creditors  of 
instrumentalities, 
including  Ambac  and  Ambac-insured  bondholders.  If  the 
Commonwealth  Plan  of  Adjustment  were  confirmed  in  its 
current  form,  Ambac's  financial  condition  would  suffer  a

Political Developments

In  2020,  President  Donald  J.  Trump  appointed  Justin  Peterson, 
Betty A. Rosa, John E. Nixon and Antonio L. Medina Comas as 
new  members  of  the  Oversight  Board  and  reappointed  Andrew 
G. Biggs, David Skeel and Arthur Gonzalez to new terms. 

The  Puerto  Rico  gubernatorial  election  was  held  on  November 
3, 2020, to elect the governor of Puerto Rico, concurrently with 
the  election  of  the  Resident  Commissioner,  the  Senate,  the 
House  of  Representatives,  and 
the  78 
municipalities.  Pedro  Pierluisi  of  Puerto  Rico’s  pro-statehood 
New Progressive Party was voted to become the territory’s next 
governor in 2021. In terms of the local legislature, there will be 
a  “shared  government”; 
the  Resident 
Commissioner from the PNP and Legislative leadership from the 
PDP. The new President of the Senate will be Senator Jose Luis

negotiations, timing and ultimate recoveries for Ambac. 

Ambac Title III Litigation Update

AAC is party to a number of litigations related to its Puerto Rico 
exposures,  and  actively  participates  in  the  Commonwealth’s 
Title III proceedings before the United States District Court for 
the District of Puerto Rico. 

On  January  16,  2020,  AAC,  together  with  other  monoline 
insurers,  filed  motions  which  sought  to  lift  the  automatic  stay 
and  allow  AAC  and  others  to  enforce  their  rights  related  to 
PRHTA, PRCCDA and PRIFA in an alternative forum. Through 
orders  issued  on  July  2  and  September  9,  2020,  Judge  Swain 
largely  denied  the  motions,  while  holding  in  abeyance  further 
proceedings  in  the  PRCCDA  motion  relating  to  a  particular 
account  over  which  it  is  undisputed  the  monolines  have  a  lien.  
AAC  and  the  other  movants  have  appealed  the  PRHTA  and 
PRIFA  decisions.    Briefing  concluded  in  late  December  with 
oral  argument  heard  in  February  2021.    Ambac  is  unable  to 
predict  when  and  how  the  issues  raised  in  these  cases  will  be 
resolved.  If  AAC  is  unsuccessful  in  any  of  these  proceedings, 
Ambac’s  financial  condition,  including  liquidity,  loss  reserves 
and capital resources may suffer a materially negative impact.

On  January  16,  2020,  the  Oversight  Board  filed  four  adversary 
proceeding complaints against AAC and other monoline insurers 
seeking 
the 
Commonwealth as they relate to PRHTA, PRCCDA, and PRIFA 
bonds.  On  April  28,  2020,  the  Oversight  Board  filed  partial 
motions  for  summary  judgment.  Briefing  has  concluded  on 
those  motions  for  summary  judgment  and  oral  argument  was 
held on September 23, 2020. On January 20, 2021, the District 
Court  granted  defendants’ 
the 
adjudication of the summary judgment motions until defendants 
have the opportunity to conduct certain discovery. Discovery is 
ongoing. 

for  deferral  of 

request 

AAC,  along  with  other  monoline  insurers,  filed  a  motion 
seeking  appointment  of  trustees  under  Section  926  of  the 
Bankruptcy Code to pursue certain avoidance actions on behalf 
of  PRHTA  against  the  Commonwealth  of  Puerto  Rico.    The 
motion  attached  a  proposed  complaint  detailing  the  avoidance 
claims  that  movants  would  pursue.    On  August  11,  2020,  the 
Court denied the motion and AAC and the other movants have 
appealed that denial. AAC and the other movants filed a motion 
to  hold  that  appeal  in  abeyance  pending  the  First  Circuit’s 
resolution of the appeal from the Court’s denial of the PRHTA 
lift-stay motion (as described above). Briefing on both motions 
concluded  on  October  27,  2020.  On  December  22,  2020,  the 
First  Circuit  denied  the  motion  to  hold  the  appeal  in  abeyance, 
and referred the motion to dismiss to the panel determining the 
merits  of  the  appeal.  Movants’  opening  brief  before  the  First 
Circuit was filed on February 17, 2021.

Mediation

The  status,  timing  and  subject  of  any  past  or  future  mediation 
discussion has not yet been publicly disclosed. The timeline for 
resolution  of  Puerto  Rico’s  debt  restructuring  process  is 
uncertain. 

The Oversight Board disclosed, in a status report filed with the 
Title  III  court  in  September  2020,  that  it  has  resumed  formal 
discussions  with  creditors  with  the  guidance  of  the  mediation 
team led by Judge Houser. Prior to the talks with creditors, the 
Oversight  Board  held  discussions  with  the  Puerto  Rico  Fiscal

The full extent of federal government support to Puerto Rico is 
still  uncertain  as  existing  federal  stimulus  has  not  been  fully 
disbursed  and  additional  measures  are  likely  to  be  enacted.  A 
new U.S. President, Puerto Rico governor, and Oversight Board 
makeup could all accelerate the aid distribution process if there 
was  a  higher  comfort  level  from  the  federal  government 
regarding the local management and efficacy of federal disaster 
resources.  Furthermore,  a  change  in  the  federal  government's 
approach  to  Puerto  Rico's  needs,  including  Social  Security 
disability  payments,  Medicaid,  and  other  health  and  nutritional 
assistance  programs,  is  possible  under  the  new  administration. 
But  while  the  previously  allocated  hurricane  disaster  relief 
funds,  the  more  recent  COVID-19  crisis  related  funds  and 
potential  new  federal  support  are  all  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.

Summary

Ambac  has  considered  these  developments  and  other  factors  in 
evaluating its Puerto Rico loss reserves.  During the year ended 
December 31, 2020, Ambac had incurred losses associated with 
its  Domestic  Public  Finance  insured  portfolio  of  $256  million, 
which  was  impacted  by  lower  discount  rates,  the  continued 
uncertainty  and  volatility  of  the  situation  in  Puerto  Rico, 
including  the  potential  impact  of  the  COVID-19  crisis  on  the 
Commonwealth  and  the  developing  potential  impact  of  the 
COVID-19  crisis  on  other  sectors  in  the  Domestic  Public 
Finance insured portfolio; and loss adjustment expenses related 
to  the  cost  of  defending  our  rights  and  pursuing  recoveries. 

| Ambac Financial Group, Inc.   39   2020 FORM 10-K |

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  and  the  overall  uncertain 

impact of the COVID-19 crisis on  the Commonwealth and the 
Domestic  Public  Finance  Insured  Portfolio  in  general.    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  17.

Internal  credit  ratings  are  provided  solely  to  indicate  the  underlying  credit  quality  of  guaranteed  obligations  based  on  the  view  of  Ambac.  In  cases 
where Ambac 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  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 $214 at December 31, 2020.

(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 $23 in January 2021.

(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 the event Commonwealth available revenues and any 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, including debt service on the obligations subject to 
such  provision  as  described  above  (to  the  extent  payable  from  such  revenues),  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,  2021,  from  its  prior  December  31,  2020, 
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 $39.

U.S. Structured Finance Portfolio 

Ambac’s  portfolio  of  U.S.  structured  finance  exposures  is 
$6,337  million,  representing  19%  of  Ambac’s  net  par 
outstanding as of December 31, 2020, and a 16% reduction from 

the amount outstanding at December 31, 2019. This reduction in 
exposure  was  primarily  related  to  residential  mortgage-backed 
securities ("RMBS") policies, which continued to prepay as well 
as incur claims.

Current  insured  exposures  include  securitizations  of  mortgage 
loans,  home  equity  loans  and  student  loans  as  well  as  other 
asset-backed financings, in each case where the majority of the 
underlying  collateral  risk  is  situated  in  the  United  States. 
Additionally,  Ambac’s  structured  finance  insured  portfolio 
includes  secured  and  unsecured  debt  issued  by  investor-owned 
utilities  and  structured 
transactions  providing 
insurance 
insurance  on  the  notes  of  trusts  established  in  connection  with 
the  reinsurance  of  defined  blocks  of  life  insurance  that  were 
used to fund regulatory reserves associated with level premium 
term life insurance policies (commonly referred to as Regulation 
XXX reserves).

See  Note  7.  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, 
2020. 

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.  AAC  seeks  to  mitigate  and  manage  these  risks 
through its risk management practices. 

Ambac  has  exposure  to  the  U.S.  mortgage  market  primarily 
through  direct  financial  guarantees  of  RMBS, 
including 
transactions that contain risks to first and second lien mortgages.  
Ambac's total net par exposure to RMBS at December 31, 2020, 
was  approximately  $3,635  million  ($2,137  million,  $1,399 
million,  $99  million  are  first  lien,  second  lien  and  other 
respectively), a decrease of 18% during 2020.  At December 31, 
2020, 88% 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 
$12,054  million,  representing  36%  of  Ambac’s  net  par 
outstanding as of December 31, 2020, and a 6% reduction from 
the amount outstanding at December 31, 2019. This reduction in 
exposure  was  primarily  the  result  of  policy  terminations,  
refinancings  and  scheduled  maturities  within  stadiums  and 
investor-owned  utilities,  partially  offset  by  a  weakening  of  the 
US  dollar  versus  the  British  pound.  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  credits. 
Ambac  has  no  insured  exposure  related  to  emerging  markets.  
See  Note  7.  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, 
2020.

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

Ambac UK, which is regulated in the United Kingdom (“UK”), 
had  been  AAC’s  primary  vehicle  for  directly  issuing  financial 
guarantee  policies  in  the  UK  and  the  European  Union  with 
$11,186 million net par outstanding at December 31, 2020. 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. 

European Union Exposures (“EU”)

Ambac's  international  net  par  exposures  are  principally  in  the 
United  Kingdom  ($9,711  million);  however,  we  also  have 
exposures  with  credit  risk  based  in  various  EU  member  states, 
including  Austria,  France,  Germany  and  Italy  ($1,797  million).  
Italy,  with  net  par  exposure  of  $803  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 January 2020 the UK Government and EU ratified the terms 
of  a  legal  binding  treaty  ("Withdrawal  Agreement")  setting  out 
the  terms  of  a  transition  period  to  apply  to  the  UK  until 
December 31, 2020. The effect of the withdrawal agreement was 
to retain the rights and obligations between the UK and the EU 
from the date of the UK's exit from the EU on January 31, 2020, 
("Exit Day") to the end of this transition period.

Prior  to  December  31,  2020,  Ambac  UK  either  commuted  any 
policies with EU based policyholders or transferred the benefits 
of those policies to UK policyholders.  In addition, Ambac UK 
transferred the administration of its last remaining policy within 
its Italian Branch to the UK on December 1, 2020, and closed its 
Italian Branch on December 18, 2020.  Therefore, while Ambac 
UK's net  par exposures  continue to  contain  credit risk based  in 
EU member states, Ambac UK no longer services any insurance 
policies with EU based policyholders and its ability to continue 
to  service  its  insurance  portfolio  is  therefore  not  impacted  by 
Brexit.

Additional Insured Portfolio Information 

Average Life of Insured Portfolio 

Ambac underwrote and priced financial guarantees based on the 
assumption  that  the  guarantees  would  remain  in  force  until  the 
maturity  of  the  underlying  bonds.  Ambac  estimates  that  the 
average  life  of  its  guarantees  on  par  in  force  at  December  31, 
2020 is approximately 10 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.

December  31,  2020  and  2019,  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. 

(2) 

Includes  $308  and  $311  of  military  housing  net  par  at 
December 31, 2020 and 2019, respectively.

The  net  decline  in  below  investment  grade  exposures  is 
primarily  due  to  commutation  of  certain  general  obligation 
exposures,  the  partial  commutation  of  a  structured  finance 
transaction  mostly  offset  by  the  addition  of  certain  exposures 
driven  by  the  COVID-19  pandemic  (lease  and  tax-backed, 
stadiums and an international structured finance exposure). 

Below  investment  grade  exposures  could  increase  as  a  relative 
proportion  of  the  guarantee  portfolio  given  that  stressed 
borrowers generally have less ability to prepay or refinance their 
debt.    Accordingly,  due  to  these  and  other  factors,  it  is  not 
unreasonable to expect the proportion of below investment grade 
exposure in the guarantee portfolio to continue to increase in the 
future.

Ceded Reinsurance

AAC has reinsurance in place pursuant to surplus share treaties 
and  facultative  agreements.  As  a  primary  financial  guarantor, 
AAC  is  required  to  honor  its  obligations  to  its  policyholders 
whether  or  not  its  reinsurers  perform  their  obligations  under 

to  defray 

these  reinsurance  agreements.  For  exposures  reinsured,  AAC 
generally  withholds  a  ceding  commission 
its 
underwriting and operating expenses. To minimize its exposure 
to  losses  from  reinsurers,  AAC  (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 AAC in the event of rating agency downgrades of a 
reinsurer  (among  other  events  and  circumstances).  AAC  held 
letters  of  credit  and  collateral  amounting  to  $117  million  from 
its reinsurers at December 31, 2020. As of December 31, 2020, 
the aggregate amount of insured par ceded by AAC to reinsurers 
under  reinsurance  agreements  was  $5,182  million,  with  the 
largest reinsurer accounting for $2,398 million or 6.1% of gross 
par outstanding at December 31, 2020.

statements included in this Form 10-K, as well as Part II, "Item 
7,  Management's  Discussion  and  Analysis's  of  Financial 
Condition and Results of Operations" of our Form 10-K for the 
year  ended  December  31,  2019,  which  provides  additional 
information on comparisons of years 2019 and 2018.

Net loss attributable to common stockholders for the year ended 
December  31,  2020,  was  $437  million  compared  to  a  net  loss 
attributable to common stockholders of $216 for the year ended 
December 31, 2019.  The increase in loss was primarily driven 
by: (i) higher loss and loss expenses, (ii) receipt of $142 million

2019 includes proceeds received in connection with an SEC action 
against  Citigroup  Global  Markets  Inc.  in  the  amount  of  $142 
million. 

In  connection  with  the  AMPS  Exchange,  the  difference  between 
the fair value of consideration provided to AMPS holders and the 
carrying amount of the AMPS has been reflected as a reduction to 
Net  income  attributable  to  common  stockholders  in    2018  for 
approximately  $82.  Refer  to  Note  1.  Background  and  Business 
Description for a discussion of the AMPS Exchange.

Ambac's  results  of  operations  and  financial  position  have  been 
adversely  impacted  by  the  COVID-19  pandemic's  effect  on  the 
global economy and financial markets.  Significant interest rate 
declines  during  2020  contributed  to  a  net  increase  in  loss 
reserves and losses on interest rate derivative contracts.  Credit 
driven  losses  were  also  recognized  in  the  three  months  ended 
March  31,  2020,  within  losses  incurred  (primarily  from  public 
finance  insurance  policies)  and  losses  in  counterparty  credit 
adjustments  on  derivative  asset  valuations.  Financial  market 
disruptions  were  reflected  through  lower  valuations  of  certain 
fixed maturity securities (recorded through other comprehensive 
income) and the majority of other investments (recorded through 
net investment income). During the last three quarters of 2020,

(favorably 

recovered 

spreads 

largely 

evolving  in  ways  that  are  difficult  or  impossible  to  anticipate.  
As a result, it is possible that Ambac's results of operations and 
financial  condition  may  be  further  adversely  affected  by  the 
evolving  affects  of  the  COVID-19  pandemic.  For  additional 
information  on  the  risks  posed  by  COVID-19,  refer  to  “Part  I, 
Item 1A-Risk Factors” in this Form 10-K.

During  2019,  Ambac  executed  on  a  number  of  restructuring  / 
commutation  transactions  that  had  significant  impacts  to  the 
consolidated results of operations.  As described further below, 
the  completion  of  the  these  transactions,  including  the  related 
changes  to  invested  assets,  intangible  assets,  loss  reserves  and 
debt  of  the  Company,  had  a  significant  impact  on  the 
comparability  of  the  results  of  operation  for  the  years  ended 
December  31,  2020,  2019  and  2018.    The  most  significant 
transactions were:

the  POA, 

Puerto  Rico  COFINA  Plan  of  Adjustment  ("POA").    On 
February  12,  2019, 
including  certain  related 
commutation transactions, and subsequent distributions, became 
effective,  resulting  in  a  significant  reduction  of  AAC's  insured 
net  par  exposure  to  COFINA.    Pursuant  to  the  COFINA  POA, 
approximately 75% of holders of AAC-insured senior COFINA 
bonds  (including  Ambac)  elected  to  commute  their  insurance 
policy.    Under  this  restructuring,  Ambac-insured  COFINA 
bonds that were not commuted were deposited, along with new 
uninsured COFINA bonds, into a newly formed trust called the 
COFINA  Class  2  Trust  ("COFINA  Trust"),  a  VIE  that  Ambac 
determined  must  be  consolidated.    Sales  of  assets  from  the 
COFINA  Trust  may  be  made  from  time  to  time  with  proceeds 
used to redeem the trust's debt.

Ballantyne Re plc ("Ballantyne") Restructuring. On April 25, 
2019,  Ballantyne  commenced,  under  Irish  law,  a  restructuring 
transaction  ("Restructuring")  in  respect  of  its  obligations, 
including obligations that were guaranteed by Ambac UK.  The 
arrangement  was  approved  on  June  17,  2019.    With  the 
successful implementation of the Restructuring, Ambac UK has 
ceased  to  have  any  exposure  with  respect  to  the  obligations  of 
Ballantyne. 

The  following  paragraphs  describe  the  consolidated  results  of 
operations of Ambac for 2020 and 2019.

Net  Premiums  Earned.      Net  premiums  earned  for  the  year 
ended December 31, 2020, decreased by $12 million or 18% as 
compared to net premiums earned for the year ended December 
31, 2019. 

remaining  unearned  premium 

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, 
is 
any 
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.

Finance  transactions.    Since  the  maturity  date  of  pre-

Net  Investment  Income.    Net  investment  income  primarily 
consists of interest and net discount accretion on fixed maturity 
securities  classified  as  available-for-sale,  and  net  gains  (losses) 
on pooled investment funds which include changes in fair value 
of  the  funds'  net  assets.    Fixed  maturity  securities  include 
investments 
that  are  made 
opportunistically  based  on  their  risk/reward  and  asset-liability 
management  characteristics. 
  As  described  further  below, 
investment  income  from  holdings  of  Ambac-insured  securities 
(including Secured Notes issued by Ambac LSNI, LLC) for the 
restructuring 
periods  presented  have  been  affected  by 
transactions  involving  Puerto  Rico  COFINA  and  Ballantyne 
bonds.    Investments  in  pooled  investment  funds  and  certain 
other investments are either classified as trading securities with 
changes  in  fair  value  recognized  in  earnings  or  are  reported 
under the equity method.  These funds and other investments are 
reported  in  Other  investments  on  the  Consolidated  Balance 

Sheets.  For  further  information  about  investment  funds  held, 
refer  to  Note  11.  Investments  to  the  Consolidated  Financial

Net  investment  income  decreased  $106  million  for  the  year 
ended  December  31,  2020  compared  to  2019.    As  described 
further  below,  the  variances  were  primarily  driven  by  2020 
pricing  volatility  within  fund  investments  resulting  from  the 
impact of the COVID-19 pandemic on financial markets and the 
impact  of  de-risking  transactions  in  2019,  including  lower 
subsequent  allocations 
to  higher  yielding  Ambac-insured 
securities and a lower overall invested asset base. 

• Investment 

income 

from  Ambac-insured 

securities 
decreased  $59  million  in  2020,  compared  to  2019.    The 
decrease  was  due  primarily  to  the  effects  of  the  2019  de-
risking  of  Ballantyne  and  lower  income  on  Secured  Notes 
issued by Ambac LSNI, LLC.  The Ballantyne restructuring 
in June 2019 resulted in accelerated discount accretion into 
income  and  settled  the  Ballantyne  bonds  held  in  the 
investment  portfolio.    Income  on  the  Secured  Notes 
declined from 2019 due to quarterly early redemptions and 
the impact of lower rates, as the coupon rate is indexed to 
LIBOR  subject  to  a  1.0%  LIBOR  floor.    Additionally, 
income  on  Ambac  insured-RMBS  declined  compared  to 
2019  primarily  as  a  result  of  declining  interest  rates  over 
both 2020 and 2019.  

• Net  investment  income  from  available-for-sales  securities 
other than Ambac-insured securities decreased $34 million 
in 2020, compared to the prior year.  The decrease resulted 
from  the  favorable  impact  of  high  yielding  uninsured 
COFINA  bonds  received  under  the  POA  on  2019  income, 
as  well  as  the  impact  of  a  smaller  asset  base  and  lower 
average  yields  in  2020.    All  of  the  uninsured  COFINA 
bonds  received  under  the  POA  were  sold  from  Ambac's 
non-VIE investment portfolio by December 31, 2019, with 
reinvestment in lower yielding fixed maturities or allocated 
to pooled funds included in Other investments.  Additional 
re-allocation  of  the  portfolio  in  2020  toward  pooled  funds 
and Ambac-insured bonds from investment grade corporate 
bonds,  commercial  mortgage backed securities and certain 
CLOs  resulted  in  a  lower  asset  base  and  average  yield  in 
this portion of the portfolio.  The use of cash for early debt 
redemptions  and  operating  cash  needs  also  contributed  to 
the  smaller  asset  base,  while 
  steadily  declining 
reinvestment  rates  on  short-term  holdings  adversely

• Other  investments  income  decreased  $13  million  in  2020, 
compared to the prior year.  The decrease resulted from the 
financial  market  impact  of  the  COVID-19  pandemic  and  
in  2020, 
fund 
repositioning  of  pooled 
compared  to  strong  portfolio  returns  in  2019.    Other 
investments  income  for  2020  included  lower  returns  on 
equity, high-yield and loan funds, partially offset by higher 
income  from  hedge  fund  investments.    Higher  income  on 
hedge  funds  was  driven  primarily  by  net  gains  on  
investments  funded  mostly  following  the  initial  broad 
market  decline  of  the  first  quarter.    Decreased  holdings  of 
equity,  high  yield  and  loan  funds  in  the  first  half  of  2020 
resulted  in  recognition  of  only  modest  net  gains  on  such 
holdings  for  the  full  year,  compared  to  above  average 
performance in these asset types in 2019.

Net  realized  gains  on  securities  sold  or  called  during  the  year 
ended  December  31,  2020,  are  primarily  from  sales  in 
connection  with  routine  portfolio  management.    Net  realized 
gain on securities sold or called for the year ended December 31, 
2019, included $50 million of net gains related to the impact of 
the  COFINA  POA,  including  sales  of  Ambac-insured  Puerto 
Rico  COFINA  bonds  and  new  uninsured  COFINA  bonds 
received in the commutation.  Also included in realized gains for 
the year ended December 31, 2019, are $23 million of realized 
foreign exchange gains arising from the settlement of Ballantyne 
bonds held in the investment portfolio.

Impairments  are  reported  through  earnings  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.  Credit  impairments  are  recorded  in  earnings  only  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  the 
securities, before recovery of their amortized cost. When credit 
impairments  are  recorded,  any  non-credit  related  impairment 
amounts  on  the  securities  are  recorded  in  other  comprehensive 
income.

Net Gains (Losses) on Derivative Contracts.  Net gains (losses) 
on  derivative  contracts  includes  result  from  the  Company's 
interest rate derivatives portfolio and its runoff credit derivative 
portfolio.  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.    As  forward  rates  and  interest  rate  exposures 
elsewhere in the company have declined over the course of 2019 

and 2020, the economic hedge position has been adjusted.  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  portfolio,  and  the  impact  of  counterparty 
credit  adjustments  as  discussed  below.    Results  from  credit 
derivatives were not significant to the periods presented.

• Net  losses  on  interest  rate  derivatives  for  the  year  ended 
December  31,  2020,  were  $50  million,  compared  to  $51 
million  for  the  year  ended  December  31,  2019.    The  net 
loss  for  the  year  ended  December  31,  2020,  reflects 
significant  declines  in  forward  interest  rates,  triggered  by 
the  COVID-19  pandemic,  and  losses  from  the  application 
of counterparty credit adjustment, described further below.  
The  net  losses  for  the  year  ended  December  31,  2019, 
reflect  the  impact  of  declines  in  forward  interest  rates, 
partially offset by negative net carrying costs driven by an 
inverted yield curve.  Although interest rates declined more 
in 2020 than in 2019, their impact on derivative losses was 
lower due to the relative positioning of the portfolio in each 
period.

• Counterparty  credit  adjustments  are  generally  applicable 
for uncollateralized derivative assets that may not be offset 
by  derivative  liabilities  under  a  master  netting  agreement.

valuation  of  interest  rate  derivatives  resulted  in  losses 
within  Net  gains  (losses)  on  derivative  contracts  of  $(6) 
million and $(2) million for the years ended  December 31, 
2020  and  2019,  respectively.    The  loss  for  the  year  ended 
December  31,  2020,  was  driven  by  wider  credit  spreads 
reflecting  the  credit  rating  downgrade  of  a  derivative 
first  quarter, 
counterparty  by  Ambac  during 
simultaneous  with  an  increase  in  the  underlying  asset 
values as interest rates declined. The losses on counterparty 
credit adjustments for the 2019 periods are primarily due to 
increases  in  the  underlying  asset  values  as  interest  rates 
declined.

the 

Other  income  (expense).    Other  income  (expense)  included 
various  fees,  primarily  consent  and  waiver  fees,  as  well  as 
foreign exchange gains (losses) unrelated to investments or loss 
reserves.    Other  income  also  included  proceeds  received  by 
AAC  in  September  2019  in  connection  with  an  SEC  action 
against  Citigroup  Global  Markets  Inc.  in  the  amount  of  $142 
million.   

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 initially 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) projected cash flows from 
(to)  the  VIEs  which  are  attributable  to  Ambac’s  insurance 
subsidiaries  in  the  form  of  financial  guarantee  insurance 

| Ambac Financial Group, Inc.   46   2020 FORM 10-K |

 
 
 
 
 
 
 
 
 
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.  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  $5  million  and 
$38  million  for  the  years  ended  December  31,  2020  and  2019, 
respectively.    Results  for  the  year  ended  December  31,  2020, 
were  due  primarily  to  realized  gains  of  $8  million  on  sales  of 
assets  from  the  COFINA  Trust  partially  offset  by  the  lower 
valuation of net assets on a VIE impacted by COVID-19.  

Results for the year ended December 31, 2019, were driven by 
the  impact  of  the  creation  and  subsequent  activities  of  the 
COFINA  Trust.    Income  from  COFINA  Trust  for  the  the  year 
ended  December  31,  2019,  was  $26  million,  including  $15 
million  from  consolidation  and  $13  million  from  realized 
investment gains on sales of assets from the trust, partially offset 
by  net  interest  expense  and  fees.  Income  for  the  year  ended 
December 31, 2019, also included a gain on the fair value of net 
assets of a VIE arising from an increase in projected cash flows 
on  the  VIE's  assets  due  to  higher  financial  guarantee  insurance 
premiums.    Results  for  2019  also  included  a  loss  of $2  million 
from deconsolidation of a VIE.

Refer  to  Note  4.  Variable  Interest  Entities  to  the  Consolidated 
Financial  Statements  included  in  this  Annual  Report  on  Form 
10-K for further information on the accounting for VIEs.

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.

Ambac  records  as  a  component  of  its  loss  reserve  estimate

transactions  with  respect  to  which  AAC  is  pursuing  claims  for 
breaches  of  representations  and  warranties.  Ambac  does  not 
include  potential  recoveries  attributed  solely  to  fraudulent 
inducement  claims  in  our  litigations  in  our  estimate  of 
subrogation  recoveries.  Generally,  the  sponsor  of  an  RMBS 
transaction provided representations and warranties with respect 
to the securitized loans, including representations with respect to 
the  loan  characteristics,  the  absence  of  borrower  fraud  in  the 
underlying  loan  pools  or  other  misconduct  in  the  origination 
process  and  attesting  to  the  compliance  of  loans  with  the 
prevailing  underwriting  policies.  Ambac  has 
recorded 
representation  and  warranty  ("R&W")  subrogation  recoveries, 
net  of  reinsurance,  of  $1,725  million  and  $1,702  million  at 
December  31,  2020  and  2019,  respectively.  The  increase  in 
these  recoveries  was  primarily  driven  by  lower  discount  rates 
used to discount estimated cash flows.  Refer to Note 2. Basis of

estimated  representation  and  warranties  for  the  year  ended 
December  31,  2020,  2019  and  2018  was  ($23),  $42  and  $62, 
respectively.  

(2)   Includes loss expenses incurred of $103, $78 and $92 for the year 

ended December 31, 2020, 2019 and 2018, respectively.

Losses and loss expenses for 2020 were driven by the following:

• Higher  projected  losses  in  domestic  public  finance  driven 
by lower discount rates (primarily relating to Puerto Rico), 
loss  expenses  incurred  and  incurred  losses  related  to 
transactions  directly  impacted  by  the  economic  impact 
from COVID-19;  and

• An  increase  in  student  loan  losses  as  a  result  of  lower 
discount  rates  and  the  impact  from  COVID-19;  partially 
offset by

• Improved RMBS losses as a result of the positive impact of 
lower  interest  rates  on  excess  spread,  reduced  by  lower 
discount rates and expected losses from COVID-19 related 
delinquencies.

Losses and loss expenses for 2019 were driven by the following:

• Higher  projected  losses  in  domestic  public  finance  driven 
mostly by lower discount rates and additions to Puerto Rico 
loss reserves, partially offset by;

• Favorable  development  within  Ambac  UK  and  Other 

Credits primarily due to the Ballantyne commutation;

• Favorable  RMBS  development  as  a  result  of  credit 
improvement, the impact on excess spread from declines in 
interest  rates  and  a  trustee  settlement  related  to  Lehman 
sponsored  transactions,  partially  offset  by  RMBS  R&W 
litigation  loss  expenses  incurred  and  a  reduction  to 
estimated RMBS R&W subrogation recoveries.

Insurance  Intangible  Amortization. 
intangible 
amortization  was  $57  million  and  $295  million  for  the  years 
ended December 31, 2020 and 2019, respectively.  The decrease 
in  intangible  amortization  for  the  year  ended  December  31, 
2020,  compared  to  2019,  is  primarily  due  to  accelerated 
amortization  as  a  result  of  the  Ballantyne  commutation  that 
occurred in 2019.

Gross operating expenses for the year ended December 31, 2020 
are $92 million, a decrease of $10 million from gross operating 
expenses for the year ended December 31, 2019.  The decrease 
was primarily due to the following:

• Lower  compensation  costs  primarily  due  to:  (i)  lower 
salaries and severance resulting from continued right sizing 
of  staffing  levels  partially  offset  by  hiring  in  connection 
with the launch of Everspan Group and (ii) lower incentive 
compensation  costs  primarily  related  to  the  Ballantyne 
restructuring incentive compensation recognized in 2019

• Lower  non-compensation  costs  primarily  due  to:  (i)  a  UK 
Value  Added  Tax  (VAT)  refund  recognized  in  2020,  (ii) 
lower  premises  costs  as  a  result  of  relocating  Ambac's 
corporate  headquarters,  and  (iii)  lower  subscription  and 
data  access  costs  associated  with  runoff  of  the  financial 
guarantee  portfolio  partially  offset  by:  (i)  increased  legal 
fees and (ii) incremental costs arising due to the COVID-19 
pandemic.

Legal  and  consulting  services  provided  for  the  benefit  of  OCI 
were  flat  at  $2  million  during  the  years  ended  December  31, 
2020 and 2019.

Interest Expense.  Interest expense includes accrued interest on 
the  Ambac  Note,  Tier  2  Notes,  surplus  notes  and  other  debt 
obligations.  Additionally,  interest  expense  includes  discount 
accretion  when  the  debt  instrument  carrying  value  is  at  a 
discount to par. 

The following table provides details by type of obligation for the 
periods presented:

Surplus  note  principal  and  interest  payments  require  the 
approval of OCI. Since the issuance of the surplus notes in 2010, 
OCI  has  declined  to  approve  regular  payments  of  interest  on 
surplus  notes,  although  the  OCI  has  permitted  exceptional 
payments  in  connection  with  (a)  increasing  the  percentage  of 
deferred policy payments of the Segregated Account of Ambac 
Assurance  from  25%  to  45%  in  2014  and  (b)  a  one-time 
payment of approximately six months of interest on the surplus 
notes (other than junior surplus notes) outstanding immediately 
after  consummation  of  the  Rehabilitation  Exit  Transactions  (as 
defined  in  Part  II,  Item  8,  Note  1  Background  and  Business 
Description  to  the  Consolidated  Financial  Statements  included 
in this Form 10-K) in 2018.  

to  make 

the  payment. 

In April 2020, OCI declined the request of Ambac Assurance to 
pay  the  principal  amount  of  the  surplus  notes,  plus  all  accrued 
and  unpaid  interest  thereon,  on  the  scheduled  maturity  date  of 
June  7,  2020.  As  a  result,  the  scheduled  payment  date  for 
interest,  and  the  scheduled  maturity  date  for  payment  of 
principal of the surplus notes, shall be extended until OCI grants 
approval 
  Interest  will  accrue, 
compounded  on  each  anniversary  of  the  original  scheduled 
payment  date  or  scheduled  maturity  date,  on  any  unpaid 
principal or interest through the actual date of payment, at 5.1% 
per  annum.    Holders  of  surplus  notes  will  have  no  rights  to 
enforce  the  payment  of  the  principal  of,  or  interest  on,  surplus 
notes in the absence of OCI approval to pay such amount.  The 
interest on the outstanding surplus notes and junior surplus notes 
were  accrued  for  and  Ambac  Assurance  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 
third  parties  were 
$344  million  and  $172  million,  respectively,  at  December  31, 
2020.

Provision for Income Taxes. The provision for income taxes for 
the  year  ended  December  31,  2020  and  2019,  was  a  benefit  of  
$3 million and an expense of $32 million, respectively. Income 
taxes for the year ended December 31, 2020 and 2019, includes 
provisions for income tax due in respect of Ambac UK of $(3) 
million and $36 million, respectively. 

At December 31, 2020, the Company had approximately $3,639

The  decrease  in  interest  expense  for  the  year  ended  December

redemptions  and  lower  rate  resets  of  the  floating  rate  Ambac

offset by interest compounding on the surplus notes and the Tier

Indemnity  Insurance  Company,  forming  the  Everspan 
Group.  In  order  to  obtain  an  A-  Financial  Strength  Rating 
from A.M. Best, AFG contributed an additional $82 million 
to  Everspan  Indemnity  Insurance  Company  in  February 
2021.

• In  December  2020,  AFG  further  amended  its  existing 
amended  and  restated  tax  sharing  agreement  among  AFG, 
AAC and certain affiliates (the "Third TSA Amendment"), 
in connection with which AAC paid to AFG approximately 
$28  million  of  accrued  payments  based  on  net  operating 
loss  carry-forwards  (“NOLs”)  used  by  AAC  ("tolling 
payments")  in  2017.    Under  the  Third  TSA  Amendment, 
AAC  and  AFG  agreed  to  eliminate  AAC's  requirement  to 
make  future  tolling  payments  based  on  its  utilization  of 
NOLs for any taxable year beginning on or after January 1, 
2019  in  exchange  for  a  reallocation  of  $210  million  of 
NOL's from AAC to AFG.  

• Under an inter-company cost allocation agreement, AFG is 
reimbursed by AAC 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.  OCI approved this $4 
million reimbursement for 2019 expenses, which was paid 
in March 2020.

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

It  is  highly  unlikely  that  AAC  will  be  able  to  make  dividend 
payments  to  AFG  for  the  foreseeable  future  and  therefore  cash 
and 
intercompany  cost 
allocation  agreement  and  distributions  from  Xchange  will  be 
AFG’s principal sources 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  9.  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  uses  of  liquidity  are  the  payment  of  operating 
expenses,  including  costs  to  explore  opportunities  to  grow  and 
diversify Ambac; the making of investments, which may include 
securities  issued  or  insured  by  AAC  and  other  less  liquid 
investments;  and  capital  expenditures 
to  acquire  and/or 
capitalize  new  businesses.    Contingencies  could  cause  material 
liquidity strains.

excluding  variable  interest  entities  consolidated  as  a  result  of  AAC’s  and  Ambac  UK'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 AAC’s surplus notes, the Ambac Note, Tier 2 Notes and Ambac UK debt, and payments due under

our statistical loss reserve method.

AAC Liquidity. AAC’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  AAC’s  liquidity  are 
gross installment premiums on insurance policies; principal and 
interest  payments  from  investments;  sales  of  investments; 
proceeds  from  repayment  of  affiliate  loans;  and  recoveries  on 
claim  payments,  including  from  litigation  and  reinsurance 
recoveries.  Termination  of  installment  premium  policies  on  an 
accelerated basis may adversely impact AAC’s liquidity. 

The  principal  uses  of  AAC’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 
outstanding debt, additional loans to affiliates, and purchases of 
securities  and  other  investments  that  may  not  be  immediately 
converted into cash.  In December 2020, AAC paid to AFG $28 
million of tolling payments, which as described above it will no 
longer be required to make for future tax years. 

• The  COVID-19  pandemic  had  a  negative  impact  on 
Ambac's liquidity resources as a consequence of the initial 

severe  reaction  of  the  capital  markets  and  potential  for 
prolonged  low  reinvestment  rates  on  invested  assets; 
derivative losses, which required either timely settlement or 
additional  collateral  posting;  and  higher  credit  risk  within 
the 
further  described  below.  
Nevertheless,  Ambac  has  not  yet  experienced  incremental 
demands on its liquidity, from higher claims, other than the 
aforementioned impact of derivatives.

• 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 AAC.  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.

Operations"  above  in  this  Management's  Discussion  and

interest thereon, on June 7, 2020.

intercompany 

AAC's 
its  wholly  owned 
loans  are  with 
subsidiary,  Ambac  Financial  Services  ("AFS").    AFS  uses 
interest  rate  derivatives    (primarily  interest  rate  swaps  and  US 
Treasury futures) as a partial hedge against the effects of rising 
interest  rates  elsewhere  in  the  Company,  including  on  AAC’s 
financial  guarantee  exposures.  AFS's  derivatives 
include, 
interest  rate  swaps  previously  provided  to  asset-backed  issuers 
and  other  entities  in  connection  with  their  financings.    AAC 
loans  cash  and  securities  to  AFS  as  needed  to  fund  payments 
under these derivative contracts, collateral posting requirements 
and operating expenses.  Intercompany loans are governed by an 
established  lending  agreement  with  defined  borrowing  limits 
that has received non-disapproval from OCI. 

AAC  manages  its  liquidity  risk  by  maintaining  comprehensive

Investing Activities

During 2020, AAC and Ambac UK continued to diversify their 
investment  portfolio  from  fixed  maturity  to  other  assets, 
primarily  hedge  funds  (increase  in  fair  value  of  $11  million).  
Additionally,  AFG  purchased  80%  of  Xchange  for  $74  million 
in 2020, net of cash acquired.

paydowns of VIE debt obligations of $542 million, proceeds of 
$19  million  from  the  re-issuance  of  1,386  shares  of  Ambac-
owned  AMPS  and  proceeds  of  $12  million  from  issuance  of 
Ambac UK debt.

The following represents the significant cash operating activities 
during the years ended December 31, 2020 and 2019:

Collateral

• Debt  service  on  the  Ambac  Note  was  $107  million  and 
$143  million  for  the  years  ended  December  31,  2020  and 
2019, respectively.

• In  September  2019,  AAC  received  $142  million  in 
connection  with  an  SEC  settlement  with  Citigroup  Global 
Markets Inc. 

• Cash  used  related  to  interest  rate  derivatives  was  $20 
million and $75 million for the years ended December 31, 
2020 and 2019, respectively. 

• Cash used for operating expenses were $76 million and $82 
million  for  the  years  ended  December  31,  2020  and  2019, 
respectively.

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

In  the  second  quarter  of  2020,  Ambac  monetized  a  material 
portion  of  its  investments  in  certain  assets  classes;  including 
corporate  securities  rated  below  the  'A'  rated  category,  all 
directly owned CMBS (other than Military Housing bonds), and 
approximately 50% of all CLOs (all rated investment grade) and 
acquired additional distressed Ambac-insured securities.  In the 
third  quarter  of  2020,  Ambac  began  acquiring  corporate 
securities  rated  below  'A'  again.    These  actions  resulted  in 
changes  to  the  credit  rating  distribution  of  available-for-sale 
investments  from  December  31,  2019,  to  December  31,  2020, 
illustrated in the charts below.

The  following  table  summarizes  the  composition  of  Ambac’s

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  a net amount of $141 million (cash and securities

BALANCE SHEET

Total  assets  decreased  by  approximately  $100  million  from 
December  31,  2019  to  $13,220  million  at  December  31,  2020, 
primarily due to payment of loss and loss adjustment expenses, 
interest and operating expenses, and partial redemptions of long-
term  debt.    These  were  partially  offset  by  higher  VIE  assets 
caused  by  the  impact  of  currency  changes  (strengthening  of 
pound  sterling).    Other  significant  changes  during  2020  were 
higher subrogation recoverables primarily related to increases in 
excess spread on RMBS, as a result of lower interest rates, and 
lower  premium  receivables  from  the  continued  runoff  of  the 
financial guarantee insurance portfolio. 

Total  liabilities  increased  by  approximately  $290  million  from 
December  31,  2019,  to  $12,074  million  as  of  December  31, 
2020,  primarily  due  to  higher  loss  reserves  and  higher 
consolidated VIE liabilities resulting from currency changes (as 
notes above), partially offset by lower unearned premiums from 
the  continued  runoff  of  the  financial  guarantee  insurance 
portfolio.  

As of December 31, 2020, total stockholders’ equity was $1,140 
million,  compared  with  total  stockholders’  equity  of  $1,536 
million at December 31, 2019. This decrease was primarily due 
to 
a  Total  Comprehensive  Loss  during  2020.  The 
Comprehensive  Loss  was  primarily  driven  by  the  net  loss 
attributable  to  common  stockholders  for  the  year  ended 
December 31, 2020, of $437 million and translation gains on the 
consolidation of AFG's foreign subsidiaries.of $23 million.

Reinsurance  Recoverable  on  Paid  and  Unpaid  Losses.    AAC 
has  reinsurance  in  place  pursuant  to  surplus  share  treaty  and 
facultative agreements. To minimize its exposure to losses from 
reinsurers,  AAC  (i)  monitors  the  financial  condition  of  its 
reinsurers;  (ii) 
its 
reinsurance  counterparties  under  certain  reinsurance  contracts; 
and (iii) has certain cancellation rights that can be exercised by 
AAC  in  the  event  of  rating  agency  downgrades  of  a  reinsurer 
(among  other  events  and  circumstances).  AAC  benefited  from 
letters of credit and collateral amounting to approximately $117 
million  from  its  reinsurers  at  December  31,  2020.    As  of 
December  31,  2020  and  2019,  reinsurance  recoverable  on  paid 
losses  were  $33  million  and  $26  million, 
and  unpaid 
respectively.    The  increase  was  primarily  a  result  of  adverse 
development  in  public  finance  and  student  loan  insured 
exposures.

Intangible  Assets.    Intangible  assets  includes  (i)  an  insurance 
intangible asset that was established at the Fresh Start Reporting 
Date,  representing  the  difference  between  the  fair  value  and 
aggregate  carrying  value  of  the  financial  guarantee  insurance 
and  reinsurance  assets  and  liabilities  of  $373  million  and  (ii) 
intangible  assets  of  $38  million  established  as  part  of  the 
acquisition of Xchange on December 31, 2020.   Refer to Note 
3. Business Combination for further information relating to this 
acquisition.

As of December 31, 2020 and 2019 the net insurance intangible

represented  41%  and  33%  of  the  2020  and  2019  combined 
investment portfolios, respectively.

Premium Receivables. Ambac's premium receivables decreased 
to  $370  million  at  December  31,  2020,  from  $416  million  at 
December  31,  2019.    As  further  discussed  in  Note  8.  Financial 
Guarantee Insurance Contracts, in this Annual Report Form 10-
K  located  in  Part  II.  Item  8,  the  decrease  is  due  to  premium 
receipts,  adjustments  for  changes  in  expected  and  contractual 
cash  flows  and  increases  to  the  allowance  for  credit  losses, 
partially offset by accretion of the premium receivable discount. 

Derivative  Assets  and  Liabilities.  The  interest  rate  derivative 
portfolio  is  positioned  to  benefit  from  rising  rates  as  a  partial 
hedge  against  interest  rate  exposure  in  the  financial  guarantee 
and  investment  portfolios.    Derivative  assets  and  liabilities  on 
the  balance  sheet  primarily  reflect  the  portion  of  the  portfolio 
that  is  not  subject  to  daily  cash  variation  margin  payments.     
Derivative  assets  increased  from  $75  million  at  December  31, 
2019,  to  $93  million  as  of  December  31,  2020.    Derivative 
liabilities increased from $90 million at December 31, 2019, to 
$114 million as of December 31, 2020.  The increases resulted 
primarily  from  lower  interest  rates  during  the  year  ended 
December  31,  2020.    The  interest  driven  increase  in  derivative 
assets  was  partially  offset  by  higher  counterparty  credit 
adjustments.

Variability of Expected Losses and Recoveries

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

than 

stressful  assumptions 

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 
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,  2020,  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  stressed 
outcomes  in  all  cases,  it  is  possible  that  we  could  have  stress 
case outcomes in some or even many cases.  See “Risk Factors” 
in  Part  I,  Item  1A  as  well  as  the  descriptions  of  "RMBS 
Variability,"  "Public  Finance  Variability,"  "Student  Loan 
Variability,"  and  "Other  Credits, 
including  Ambac  UK, 
Variability,"  in  Part  II,  Item  7  of  this  Annual  Report  on  From 
10-K for further discussion of the risks relating to future losses 

and  recoveries  that  could  result  in  more  highly  stressed 
outcomes appearing below.

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  Ambac,  including  (without 
limitation)  impairing  the  ability  of  AAC  to  honor  its  financial 
obligations;  the  initiation  of  rehabilitation  proceedings  against 
AAC;  decreased  likelihood  of  AAC  delivering  value  to  AFG, 
through  dividends  or  otherwise;  and  a  significant  drop  in  the 
value of securities issued or insured by AFG or AAC.  

RMBS Variability

Ambac  has  exposure  to  the  U.S.  mortgage  market  primarily 
through  financial  guarantees  of  RMBS,  including  transactions 
collateralized by first and second liens. 

Changes  to  assumptions  that  could  make  our  reserves  under-
estimated  include  an  increase  in  interest  rates,  deterioration  in 
housing prices, poor servicing, government intervention into the 
functioning of the mortgage market and the effect of a weakened 
economy  characterized  by  growing  unemployment  and  wage 
pressures.  We  utilize  a  model  to  project  losses  in  our  RMBS 
exposures and changes to reserves, either upward or downward, 
are not unlikely if we used a different model or methodology to 
project losses.

We  established  a  representation  and  warranty  subrogation 
recovery  as  further  discussed  in  Note  8.  Financial  Guarantee 
Insurance  Contracts  to  the  Consolidated  Financial  Statements 
included  in  this  Annual  Report  on  Form  10-K.    Our  ability  to 
realize RMBS representation and warranty recoveries is subject 
to  significant  uncertainty,  including  risks  inherent  in  litigation, 
collectability of such amounts from counterparties (and/or their 
respective  parents  and  affiliates),  delays  in  realizing  such 
recoveries,  including  delays  in  getting  to  trial  due  to  court 
closures  caused  by  COVID-19  or  other  events,  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.    Additionally, 
our  R&W  actual  subrogation  recoveries  could  be  significantly 
lower than our estimate of $1,725 million, net of reinsurance, as 
of  December  31,  2020,  if  the  sponsors  of  these  transactions: 
(i)  fail  to  honor  their  obligations  to  repurchase  the  mortgage 
loans, (ii) successfully dispute our breach findings or claims for 
damages, (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. Failure to realize 
R&W subrogation recoveries for any reason or the realization of 
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.

In the case of both first and second-lien exposures, the possible 
lower  housing  price  appreciation 
stress  case  assumes  a 
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,  2020,  could  be  approximately  $15  million.  

the  absence  of  any  R&W  subrogation 
Combined  with 
recoveries, a possible increase in loss reserves for RMBS could 
be approximately $1,740 million.  A loss of this magnitude may 
render AAC insolvent.  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.    Additionally,  the  RMBS  portfolio  is  sensitive  to  the 
COVID-19 related forbearances and delinquencies caused by the 
related  general  economic  downturn.    Due  to  the  uncertainties 
related to the economic effects of the COVID-19 pandemic and 
other  risks  associated  with  RMBS,  there  can  be  no  assurance 
that losses may not exceed our stress case estimates.  

Public Finance Variability

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  includes  a  wide  array  of 
non-municipal types of bonds, including financings for not-for-
profit entities and transactions with public and private elements, 
which generally finance infrastructure, housing and other public 
purpose  facilities  and  interests.    The  increase  in  public  finance 
gross  loss  reserves  at  December  31,  2020,  as  compared  to 
December  31,  2019,  was  primarily  related  to  declines  in 
discount  rates,  changes  in  assumptions  on  certain  credits, 
particularly  Puerto  Rico  and  adverse  impact  on  loss  reserves 
from  the  global  and  issuer-specific  economic  impact  of  the 
COVID-19  pandemic.    Total  public  finance  gross  loss  reserves 
and related gross par outstanding on Ambac insured obligations

It is possible our loss reserves for public finance credits may be 
under-estimated if issuers are faced with prolonged exposure to 
adverse  political,  judicial,  economic,  fiscal  or  socioeconomic 
events or trends.  Additionally, our loss reserves may be under-
estimated  as  a  result  of  the  ultimate  scope,  duration  and 
magnitude of the effects of COVID-19. The COVID-19 related 
economic  downturn  has  put  a  strain  on  municipal  issuers, 
particularly those dependent upon narrow sources of revenues or 
dedicated taxes to support debt service, such as hotel occupancy 
taxes, sales taxes, parking revenues, tolls, licensing fees, etc.  A 
prolonged  recovery  from  the  COVID-19  related  economic 
downturn  could  put  additional  stresses  on  these  issuers  as  well 
as  other  types  of  municipal  finance  issuers  and  result  in 
increased defaults and potential additional losses for Ambac.

Our experience with the city of Detroit in 2013 in its bankruptcy 
proceeding was not favorable and renders future outcomes with 
other  public  finance  issuers  even  more  difficult  to  predict  and 
may  increase  the  risk  that  we  may  suffer  losses  that  could  be 
sizable.  We agreed to settlements regarding our insured Detroit 
general  obligation  bonds  that  provide  better  treatment  of  our 
exposures  than  the  city  planned  to  include  in  its  plan  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 

| Ambac Financial Group, Inc.   56   2020 FORM 10-K |

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
significant exposure, such as Chicago's 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. 

Variability  of  outcomes  applies  to  even  what  is  generally 
considered more secure municipal financings, such as dedicated 
sales tax revenue bonds that capture sales tax revenues for debt 
service  ahead  of  any  amounts  being  deposited  into  the  general 
fund of an issuer.  In the case of the Puerto Rico COFINA sales 
tax bonds that were part of the Commonwealth of Puerto Rico's 
Title III proceedings, AAC and other creditors agreed to settle at 
a recovery rate equal to about 93% of pre-petition amounts owed 
on  the  Ambac  insured  senior  COFINA  bonds.  In  the  COFINA 
case,  the  senior  bonds  still  received  a  reduction  or  "haircut" 
despite the existence of junior COFINA bonds, which received a 
recovery rate equal to about 56% of pre-petition amounts owed. 

In  addition,  municipal  entities  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,  legal,  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 limited access to alternative forms of credit (such as 
bank  loans)  or  other  exogenous  factors,  such  as  changes  in  tax 
law  that  could  reduce  certain  municipal  investors'  appetite  for 
tax-exempt municipal bonds or put pressure on issuers in states 
with  high  state  and  local  taxes.  These  factors,  as  well  as  more 
recent  volatility  in  the  municipal  markets  as  a  result  of  the 
COVID-19  related  economic  downturn  and 
the  building 
budgetary pressures at the state and local level related to the cost 
of fighting the virus, could deprive issuers access to funding at a 
level necessary to avoid defaulting on their obligations. 

In  addition,  a  judicial  decision  in  connection  with  the  PRHTA 
Title III proceedings could cause the loss reserves on our public 
finance  credits  to  be  underestimated.  On  January  13,  2020,  the 
U.S. Supreme Court denied a petition for certiorari arising out of 
an  appeal  of  the  March  26,  2019,  ruling  by  the  U.S.  Court  of 
Appeals  for  the  First  Circuit.    In  the  ruling,  the  First  Circuit 
affirmed  the  decision  by  the  U.S.  District  Court  overseeing  the 
PROMESA  Title  III  proceedings  for  the  PRHTA,  found  that 
under Sections 928(a) and 922(d) of the U.S. Bankruptcy Code, 
municipal issuers of revenue bonds secured by special revenues 
are permitted, but not required, to apply special revenues to pay 
debt  service  on  such  revenue  bonds  during  the  pendency  of 
bankruptcy  proceedings  for  such  municipal  issuers.    The  First 
Circuit's  decision  challenges  what  had  been  a  commonly 
understood  notion  in  the  municipal  finance  marketplace  that 
municipal revenues bondholders secured by special revenues (as 
defined  in  Chapter  9  of  the  U.S.  Bankruptcy  Code)  would 
continue  to  receive  payment  during  a  bankruptcy  of  the 
municipal  issuer.  This  decision  introduces  uncertainty  into  the 
public  finance  market  and  it  may  make  it  more  difficult  for 
municipal  instrumentalities  to  procure  revenue  bond  financings 

in  the  future  and  increases  the  credit  risk  to  bondholders  of 
existing  special  revenue  bonds,  particularly  those  from  weaker 
issuers.

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, such as the developing 
COVID-19 related economic downturn.

Our  exposures  to  the  Commonwealth  of  Puerto  Rico  are  under 
stress  arising  from 
the  Commonwealth’s  poor  financial 
condition, weak economy, loss of capital markets access, and the 
severe  damage  caused  by  hurricanes  Irma  and  Maria  and  other 
natural disasters.  These factors, taken together with the payment 
moratorium  on  debt  service  of  the  Commonwealth  and  its 
instrumentalities, ongoing PROMESA Title III proceedings, and 
certain  other  provisions  under  PROMESA,  the  potential  for 
restructurings of debt insured by AAC, 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.  See  Note  17. 
Commitments  and  Contingencies  to  the  Consolidated  Financial 
Statements  in  Part  II,  Item  8  and  "Financial  Guarantees  in 
Force"  section  of  Management’s  Discussion  and  Analysis  of 
Financial  Condition  and  Results  of  Operations  included  in  Part 
II,  Item  7  in  this  Annual  Report  on  Form  10-K  for  further 
updates relating to Puerto Rico. 

the  possible 

Material  additional  losses  on  our  public  finance  credits  caused 
by  the  aforementioned  factors,  including  the  possibility  of  a 
protracted recovery related to the COVID-19 crisis would have a 
material adverse effect on our results of operations and financial 
condition. For the public finance credits, including Puerto Rico, 
for which we have an estimate of expected loss at December 31, 
2020, 
loss  reserves  could  be 
approximately  $1,200  million.  and  there  can  be  no  assurance 
that losses may not exceed our stress case estimates.  A loss of 
this magnitude may render AAC insolvent.  Among other things, 
this  estimate  includes  the  possibility  that  the  Commonwealth 
Plan  of  Adjustment  (as  discussed  above  in  the  Financial 
Guarantees in Force section of this Management Discussion and 
Analysis) were to become effective.

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,  including  the  COVID-19  related 
economic downturn.  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  by  the 
Consumer  Finance  Protection  Bureau.    For  student  loan  credits 
for which we have an estimate of expected loss at December 31, 
2020, 
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  $20  million.    Additionally,  the  student  loan 
portfolio is sensitive to COVID-19 related payment moratoriums 
and  delinquencies  caused  by  the  general  economic  downturn. 
Due  to  such  factors,  there  can  be  no  assurance  that  losses  may 
not exceed our stress case estimates.

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  $400 
million  greater  than  the  loss  reserves  at  December  31,  2020. 
Additionally,  our  loss  reserves  may  be  under  estimated  as  a 
result  of  the  ultimate  scope,  duration  and  magnitude  of  the 
effects  of  COVID-19.    There  can  be  no  assurance  that  losses 
may not exceed our stress case estimates.

Long-term Debt.  Long-term debt consists of senior and  junior 
surplus notes issued by AAC, the Ambac Note and Tier 2 Notes 
issued  in  connection  with  the  Rehabilitation  Exit  Transactions, 
and  Ambac  UK  debt  issued  in  connection  with  the  2019 
Ballantyne commutation.  The carrying value of each of these as 
of December 31, 2020 and 2019 is below:

$121 million, partially offset by accretion on the carrying value 
of the surplus notes, Tier 2 Notes and Ambac UK debt.

Redeemable Noncontrolling Interest.  The increase during 2020

ACCOUNTING STANDARDS

The  following  accounting  standards  have  been  issued  but  have 
not  yet  been  adopted.    We  do  not  expect  these  accounting 
standards  to  have  a  consequential  impact  on  Ambac's  financial 
statements.

Convertible  Instruments  and  Contracts  in  an  Entity's  Own 
Equity

In August 2020, the FASB issued ASU 2020-06, Accounting for 
Convertible  Instruments  and  Contracts  in  an  Entity's  Own 
Equity.  The  ASU  i)  simplifies  the  accounting  for  convertible 
debt and convertible preferred stock by reducing the number of 
accounting  models,  and  amends  certain  disclosures,  ii)  amends 
and  simplifies  the  derivative  scope  exception  guidance  for 
contracts  in  an  entity's  own  equity,  including  share-based 
compensation,  and  iii)  amends  the  diluted  earnings  per  share 
calculations  for  convertible  instruments  and  contracts  in  an 
entity's own equity. The ASU is effective for fiscal years ending 

after December 15, 2021, with early adoption permitted.  Ambac 
will adopt this ASU on January 1, 2022.

Simplifying Income Tax Accounting

In  December  2019,  the  FASB  issued  ASU  2019-12,  Income 
Taxes  (Topic  740)  -  Simplifying  the  Accounting  for  Income 
Taxes.    The  FASB  issued  this  ASU  as  part  of  its  initiative  to 
reduce  complexity  in  accounting  standards.  The  ASU  removes 
certain exceptions in the guidance related to investments, intra-
period allocations and interim period allocations.  It further adds 
new  guidance  related  to  the  allocation  of  consolidated  income 
taxes and evaluating a step-up in the tax basis of goodwill. The 
ASU  is  effective  for  fiscal  years  beginning  after  December  15, 
2020, with early adoption permitted.  The modified disclosures 
must  be  applied  on  a  retrospective  basis  for  all  periods 
presented.  Ambac will adopt this ASU on January 1, 2021.

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 Annual Report Form 10-K for 
the  year  ended  December  31,  2020,  for  a  discussion  of  the 
impact of other recent accounting pronouncements on Ambac’s 
financial condition and results of operations.

AAC STATUTORY BASIS FINANCIAL RESULTS

AAC 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.  
Additionally,  the  OCI  has  prescribed  additional  practices  and 
has  permitted  accounting  practices  for  AAC.    For  further 
information,  see  Note  9.  Insurance  Regulatory  Restrictions  to 
the Consolidated Financial Statements included in Part II, Item 8 
in this Annual Report Form 10-K.   

AAC’s  statutory  policyholder  surplus  and  qualified  statutory 
capital  (defined  as  the  sum  of  policyholders  surplus  and 
mandatory contingency reserves) were $865 million and $1,413 
million  at  December  31,  2020,  respectively,  as  compared  to 
$1,088  million  and  $1,618  million  at  December  31,  2019, 
respectively.  As  of  December  31,  2020,  statutory  policyholder 
surplus  and  qualified  statutory  capital  included  $573  million 
principal  balance  of  surplus  notes  outstanding,  $365  million 
principal  balance  of  junior  surplus  notes  outstanding  and  $138 
million  liquidation  preference  of  preferred  stock  outstanding. 
These  surplus  and  junior  surplus  notes  (including  related 
accrued  interest  of  $544  million  that  is  not  recorded  under 
statutory  basis  accounting  principles),  preferred  stock  and  all 
other  liabilities  (including  insurance  claims  and  debt  issued  by 
AAC) are obligations that have claims on the resources of AAC 
that  are  senior  to  AFG's  equity  and  therefore  impact  AFG's 
ability to realize  residual value or receive dividends from AAC. 

The  significant  drivers  to  the  net  decrease  in  policyholder 
surplus  were  statutory  net  losses  of  $213  million  for  the  year 
from 
ended  December  31,  2020, 

(excluding  dividends

subsidiaries)  and  contributions  to  contingency  reserves  of  $18 
million.

AAC’s  statutory  surplus  is  sensitive  to  multiple  factors, 
including: (i) loss reserve development, (ii) approval by OCI of 
interest  costs 
payments  on  surplus  notes,  (iii)  on-going 
associated  with  the  Ambac  Note  and  Tier  2  Notes,  including 
changes to the interest rates as the Ambac Note is a floating rate 
obligation,  (iv)  deterioration  in  the  financial  position  of  AAC 
subsidiaries  that  have  their  obligations  guaranteed  by  AAC, 
(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  pooled  fund  and  other 
investments  carried  at 
(ix)  settlements  of 
representation and warranty breach claims at amounts that differ 
from  amounts  recorded,  including  failures  to  collect  such 
amounts,  (x)  realized  gains  and  losses,  including  losses  arising 
from other than temporary impairments of investment securities, 
and (xi) future changes to prescribed SAP practices by the OCI. 

fair  value, 

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).    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 1.1%. 

• Mandatory  contingency  reserves  are  required  based  upon 
the  type  of  obligation  insured,  whereas  GAAP  does  not 
require such a reserve. Releases of the contingency reserves

determination that the held reserves are deemed excessive. 

• Investment  grade  fixed  maturity  investments  are  stated  at 
amortized  cost  and  certain  below  investment  grade  fixed 
maturity investments are reported at the lower of amortized 
cost  or  fair  value.  Under  GAAP,  all  fixed  maturity 
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  ("VIE")  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. AAC 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 AAC 
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. 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.

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  £412  million  at  December  31,  2020,  as 
compared to £387 million at December 31, 2019.  At December 
31, 2020, the carrying value of cash and investments was £481 
million,  a  increase  from  £470  million  at  December  31,  2019. 
The  increase  in  shareholders’  funds  and  cash  and  investments 
was  primarily  due  to  the  continued  receipt  of  premiums  and 
investment  income,  partially  offset  by  loss  expenses,  foreign 
exchange  losses  within  Ambac  UK's  investment  portfolio  and 
operating expense and tax 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  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. 

• Investments  in  fixed  maturity  securities  are  stated  at 
to  an  other-than-temporary 

amortized  cost,  subject

impairment  evaluation.  Under  U.S.  GAAP,  all  bonds  are 
reported  at  fair  value  and  are  evaluated  for  credit 
impairments under CECL,

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

• VIEs  are  not  required  to  be  assessed  for  consolidation. 
Under  U.S.  GAAP,  as  noted  under  AAC  Statutory  Basis 
Financial  Results  above,  VIE's  with  certain  characteristics 
are  required  to  be  consolidated.    For  several  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. 

• Insurance 

intangibles 

that  arose  as  a  result  of 

the 
implementation  of  Fresh  Start  reporting  is  not  a  concept 
within  UK  GAAP.    Under  U.S.  GAAP,  this  insurance 
intangible asset is amortized as an expense on a level yield 
basis over the life of the related insurance risks. 

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,  2020,  will  be 
published on Ambac's website during March 2021. Final annual 
Solvency  II  data  and  Ambac  UK's  annual  Solvency  and 
Financial  Condition  Report  will  be  published  on  Ambac's 
website during April 2021.

Available capital resources under Solvency II were a surplus of 
£196 million at December 31, 2020, of which £188 million are 
eligible  to  meet  solvency  capital  requirements.    This  is  an 
increase  from  December  31,  2019,  when  available  capital 
resources were a surplus of £184 million of which £178 million 
were  eligible  to  meet  solvency  capital  requirements.    Eligible 
capital resources at December 31, 2020 and December 31, 2019, 
are  in  comparison  to  regulatory  capital  requirements  of  £256 
million  and  £208  million,  respectively.  Therefore,  Ambac  UK 
was deficient in terms of compliance with applicable regulatory 
capital  requirements  by  £72  million  and  £30  million  at 
December 31, 2020 and December 31, 2019, respectively.  The 
deficit increased as at December 31, 2020, due to the combined 
impact  of  (i)  the  reduction  in  long  term  interest  rates,  which 
resulted  in  an  increase  in  technical  provision  liabilities  and 
hence  a  reduction  in  eligible  own  funds  and  (ii)  an  increase  in 
capital  requirements  for  non-life  risk  due  to  parameter  changes 
the  solvency  capital  requirement  calculation.  The 
within 

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  currently 
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 
is  a  numerical  measure  of  financial 
financial  measure 
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 Ambac's emergence from 
bankruptcy  and  implementation  of  Fresh  Start  reporting. 
This  adjustment  ensures 
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  
and  facilitates  period-to-period  comparisons  of  Ambac's 
operating performance.

• Non-credit

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.

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.

The decrease in Adjusted Book Value was primarily attributable 
to  the  Adjusted  Loss  for  the  year  ended  December  31,  2020, 
excluding  earned  premium  previously  included  in  Adjusted 
Book  Value,  partially  offset  by  foreign  exchange  translation 
gains.

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 and (iii) new reinsurance transactions. 

Item 7A.   Quantitative and Qualitative Disclosures 

about Market Risk

Market  risk  represents  the  potential  for  loss  due  to  adverse 
changes in the fair value of financial instruments, as a result of 
changes  in  market  rates  and  prices,  such  as  interest  rates 
(inclusive  of  credit  spreads),  foreign  currency  exchange  rates 
and other relevant market rate or price changes.  Market risk is, 
in part, a function of the markets in which the underlying assets 
are  traded.    The  Company’s  market  risk  sensitive  financial 
instruments  are  primarily  entered  into  for  purposes  other  than 
trading.    As  discussed  further  below,  the  Company’s  primary 
market  risk  exposures  include  those  from  changes  in  interest 
rates,  foreign  currency  exchange  rates  and  equity  values  of 
limited partnership and other alternative investments.  

• The  primary  market  risks  for  fixed  maturity  investment 
securities  are  interest  rate  risk  and  exchange  rate  risk. 
Ambac’s  fixed  maturity  investment  portfolio  includes 
securities  denominated  both  in  U.S.  dollars  and  foreign 
currencies,  which  are  sensitive  to  changes  in  interest  rates 
and  foreign  currency  exchange  rates.    Our  fixed  maturity 
investments  are  classified  as  available  for  sale,  with  the 
effect  of  market  movements  recognized 
immediately 
through  Other  comprehensive  income,  or  through  Net 
income  when  securities  are  sold  or  when  an  impairment 
charge is recorded.   

• Ambac  also  invests  in  limited  partnerships  and  other 
alternative  investments,  primarily  consisting  of  diversified 
pooled  investment  funds,  which  are  reported  as  Other 
investments.  These  funds  are  subject  to  equity  value 
changes driven primarily by changes to their respective net 
asset value (“NAV”).  Ambac’s share of the changes of the 
equity  value  of  the  funds  is  reported  through  Net  income.

• The  interest  rate  derivatives  portfolio  is  managed  as  a 
partial  hedge  against  the  effects  of  rising  interest  rates 
elsewhere in the Company, including on Ambac's financial 
guarantee exposures.  Changes in fair value of interest rate 
derivatives  are  recognized 
through  Net 
income.  For additional information about Ambac’s interest 
rate derivatives, see Note 12. Derivative Instruments to the

their  fair  value,  though  with  no  direct  impact  on  our

For 

Fixed maturity investment securities that are distressed Ambac-
insured  bonds  have  market  risk  characteristics  that  behave 
inversely  to  those  associated  with  future  financial  guarantee 
claim payments.  Accordingly, such securities are excluded from 
the  market  risk  sensitivity  measures  below. 
  Financial 
instruments of VIEs that are consolidated as a result of Ambac 
financial  guarantees  are  also  excluded  from  Ambac's  measures 
of market risk.  Ambac’s exposure to such consolidated VIEs is 
generally  limited  to  financial  guarantees  outstanding  on  the 
VIEs’ liabilities or assets.  See Note 4. Variable Interest Entities

Item  8  in  this  Form  10-K  for  further  information  about  VIEs 
consolidated as a result of Ambac’s financial guarantees. 

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.    This  market  information  is 
considered in management’s judgments about adverse sensitivity

scenarios that are reasonably possible to occur in the near-term.  
The  impact  of  these  scenarios  do  not  consider  the  possible 
simultaneous movement in other market rates or prices, actions 
of  management  or  other  factors  that  could  lessen  or  worsen 
actual results.  For these reasons, the valuation results from these 
models could differ materially from amounts actually realized in 
the market. The Company’s market risk exposures have changed 
over the course of 2020 primarily as a result of re-positioning of 
our  investment  and  derivative  portfolios.    Prior  year-end 
quantitative market risk sensitivity disclosures below have been 
updated to conform with the current presentation.

in  the  fair  value  of  our  fixed  maturity  investment  portfolio.  
Interest  rate  increases  would  also  have  a  negative  economic 
impact  on  expected  future  claim  payments  within  the  financial 
guarantee portfolio, primarily related to RMBS and student loan 
policies.    Conversely,  interest  rate  increases  would  generally 
result  in  fair  value  gains  on  interest  rate  derivatives  and  lower 
the fair value of our debt obligations.  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.  We also monitor our interest 
rates exposure through periodic reviews of projected cash flows 
and durations of our asset and liability positions.

UK.    The  adverse  fair  value  impact  of  a  stronger  U.S.  dollar

an  illustration  of  the  hypothetical  impact  of  adverse  market 
movements  on  Ambac’s 
investments  with  equity  value

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.

/s/ KPMG LLP

New York, New York
March 1, 2021

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

Opinion on Internal Control Over Financial Reporting

We have audited Ambac Financial Group, Inc. and 
subsidiaries' (the Company) internal control over financial 
reporting as of December 31, 2020, 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, 2020, 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, 2020 and 2019, 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, 2020, and the related notes and 
financial statement schedules I, II and IV (collectively, the 
consolidated financial statements), and our report dated March 
1, 2021 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.

Report of Independent Registered Public Accounting Firm

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

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets 
of Ambac Financial Group, Inc. and subsidiaries (the Company) 
as of December 31, 2020 and 2019, 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, 2020, and the related notes and 
financial statement schedules I, II and IV (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, 2020 and 2019, and the results of its operations 
and its cash flows for each of the years in the three-year period 
ended December 31, 2020, 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) 
(PCAOB), the Company’s internal control over financial 
reporting as of December 31, 2020, based on criteria established 
in Internal Control — Integrated Framework (2013) issued by 
the Committee of Sponsoring Organizations of the Treadway 
Commission, and our report dated March 1, 2021 expressed an 
unqualified opinion on the effectiveness of the Company’s 
internal control over financial reporting.

Basis for Opinion

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 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 audits in accordance with the standards of the 
PCAOB. Those standards require that we plan and perform the 
audit to obtain reasonable assurance about whether the 
consolidated financial statements are 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.

Critical Audit Matter

The critical audit matter communicated below is a matter arising 
from the current period audit of the consolidated financial 
statements that was communicated or required to be 

communicated to the audit committee and that: (1) relates to 
accounts or disclosures that are material to the consolidated 
financial statements and (2) involved our especially challenging, 
subjective, or complex judgments. The communication of a 
critical audit matter does not alter in any way our opinion on the 
consolidated financial statements, taken as a whole, and we are 
not, by communicating the critical audit matter below, providing 
a separate opinion on the critical audit matter or on the accounts 
or disclosures to which it relates.

Estimate of loss and loss expense reserves and subrogation 
recoverable

As described in Notes 2 and 8 to the consolidated financial 
statements, the Company estimates loss and loss expense 
reserves and subrogation recoverable (loss reserves) on a 
policy-by-policy basis based upon the present value of 
expected net claim cash outflows or expected net recovery 
cash inflows, discounted at risk-free rates. Expected net claim 
cash outflows represent the present value of expected claim 
cash outflows, less the present value of expected recovery 
cash inflows. For such policies, a loss and loss expense 
reserves liability is recorded for the present value of expected 
net claim cash outflows in excess of the related unearned 
premium revenue. Expected net recovery cash inflows 
represent the present value of expected recovery cash inflows, 
less the present value of expected claim cash outflows. For 
such policies, a subrogation recoverable asset is recorded. As 
of December 31, 2020, the Company recorded loss and loss 
expense reserves of $1,759 million and subrogation 
recoverable of $2,156 million.

We identified the evaluation of loss reserves as a critical audit 
matter. The evaluation encompassed the assessment of the 
loss reserve methodologies, including those methods used to 
estimate the following assumptions: (1) credit worthiness of 
the issuer of the insured security, (2) the likelihood of 
possible outcomes regarding the probability of default by the 
issuer of the insured security, (3) the expected loss severity 
for each insurance policy, (4) the probability of remediation, 
settlement and restructuring outcomes, and (5) the probability 
of successful litigation or related settlement outcomes, as well 
as the percentage of the breach rates of representations and 
warranties underlying certain insured residential mortgage 
backed securities. The evaluation of the methods and the 
impact of these assumptions required specialized skills and 
subjective and complex auditor judgment due to a high level 
of estimation uncertainty.

The following are the primary procedures we performed to 
address this critical audit matter. With the involvement of 
professionals with specialized industry knowledge and 
experience, when necessary, we evaluated the design and 
tested the operating effectiveness of certain internal controls 
related to the Company's estimation of loss reserves.  This 
included controls related to the determination of the sources 
of data and assumptions and the analysis of the loss reserves 
and historical trends. We inquired of internal and external 

| Ambac Financial Group, Inc.   67   2020 FORM 10-K |

legal counsel and read letters received directly from the 
Company’s internal and external legal counsel regarding the 
status of litigation underlying certain insurance policies. We 
involved credit risk professionals with specialized skills and 
knowledge, who assisted in assessing the individual issuer 
ratings and credit classifications for certain policies by 
evaluating the financial performance of the issuer of the 
insured security and underlying collateral. We involved 
forensics professionals with specialized skills and knowledge, 
who assisted in inspecting underwriting documentation for 
certain mortgage loans underlying insured residential 
mortgage backed securities, which were examined by the 
Company’s consultants engaged to determine breach rates of 
representations and warranties. We also involved valuation 
professionals with specialized skills and knowledge, who 
assisted in: 

• evaluating the methods  used to estimate loss reserves for 
compliance with U.S. generally accepted accounting 
principles

• evaluating, for certain policies, the sources of data and 
assumptions used in the calculation of loss reserves by 
comparing to internal experience and related historical 
and industry trends

• developing, for certain policies, an independent estimate 
of the loss reserves and comparing it to the recorded 
estimate.

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

1.   BACKGROUND AND BUSINESS DESCRIPTION

Ambac  Financial  Group,  Inc.  (“AFG”),  headquartered  in  New 
York City, is a financial services holding company incorporated 
in  the  state  of  Delaware  on  April  29,  1991.  References  to 
“Ambac,”  the  “Company,”  “we,”  “our,”  and  “us”  are  to  AFG 
and  its  subsidiaries,  as  the  context  requires.    Ambac's  business 
operations include:

• Financial  Guarantee  Insurance  —  Ambac  Assurance 
Corporation  ("Ambac  Assurance"  or  "AAC")  and  its 
wholly  owned  subsidiary,  Ambac  Assurance  UK  Limited 
(“Ambac UK”), legacy financial guarantee businesses, both 
of  which  have  been  in  runoff  since  2008.    Insurance 
policies 
issued  by  AAC  and  Ambac  UK  generally 
guarantee  payment  when  due  of  the  principal  and  interest 
on the obligations guaranteed. 

• Specialty  Property  &  Casualty  Program  Insurance  — 
Currently  includes  admitted  insurer  Everspan  Insurance 
Company  and  excess  and  surplus  lines  insurer  Everspan 
Indemnity Insurance Company (collectively, "Everspan" or 
the  "Everspan  Group").    This  platform,  which  received  an 
A-  Financial  Strength  Rating  from  A.M.  Best  in  February 
2021, is expected to launch new underwriting programs in 
2021.

• Managing  General  Agency  /  Underwriting  — Currently 
includes  Xchange  Benefits,  LLC  and  Xchange  Affinity 
Underwriting  Agency,  LLC  (collectively,  “Xchange”)  a 
property and casualty Managing General Underwriter 80% 
of which AFG acquired  on December 31, 2020.  Refer to 
Note  3.  Business  Combination  for  further  information 
relating to this acquisition.

financial 

information,  allocated 

As of and for the year ended December 31, 2020, management 
reviewed 
resources  and 
measured  financial  performance  on  a  consolidated  basis  and 
accordingly the Company had a single reportable segment.  As a 
result of the acquisition of Xchange and the expected launch of 
the Everspan platform, segments will be re-evaluated in 2021.

Limitations on Voting and Transfer of Common Stock

AFG’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  AFG'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  AFG’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 (as defined below).  Article XII 
contains substantial restrictions on the ability to transfer AFG’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  AFG  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  AFG’s  Board  of  Directors  to 
such  transfer.  A  purported  transferee  of  a  Prohibited  Transfer 
shall not be recognized as a stockholder of AFG 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  AFG, 
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 
AFG,  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  AFG  with 
respect  to  such  Excess  Securities,  to  an  agent  designated  by 
AFG. 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  AFG’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. 

Strategies to Enhance Shareholder Value

The  Company's  primary  goal  is  to  maximize  shareholder  value 
through executing the following key strategies:  

its  subsidiaries 

• Active  runoff  of  AAC  and 

through 
transaction terminations, commutations, restructurings, and 
reinsurance  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  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

• Further  expanding  into  specialty  property  and  casualty 
program insurance, managing general agency/underwriting 
and  potentially  other  insurance  and  insurance  related 
businesses  that  will  generate  long-term  shareholder  value

with  attractive  risk-adjusted  returns  and  meet  other 
preestablished criteria.

completed  the  restructuring  transactions  (the  "Rehabilitation 
Exit Transactions") .

The  execution  of  Ambac’s  strategy  to  increase  the  value  of  its 
investment in AAC is subject to the restrictions set forth in the 
Settlement Agreement, dated as of June 7, 2010 (the "Settlement 
Agreement"), by and among AAC, Ambac Credit Products LLC 
("ACP"), AFG and certain counterparties to credit default swaps 
with  ACP  that  were  guaranteed  by  AAC,  as  well  as  the 
Stipulation and Order among the Office of the Commissioner of 
Insurance  for  the  State  of  Wisconsin  (“OCI”),  AFG  and  AAC 
that  became  effective  on  February  12,  2018,  as  amended  (the 
“Stipulation and Order”), and the indenture for the Tier 2 Notes 
(as  defined  below),  each  of  which  requires  OCI  and,  under 
certain  circumstances,  holders  of 
instruments 
benefiting  from  such  restrictions,  to  approve  certain  actions 
taken by or in respect of AAC.  In exercising its approval rights, 
OCI  will  act  for  the  benefit  of  policyholders,  and  will  not  take 
into account the interests of AFG.

the  debt 

Opportunities  for  remediating  losses  on  poorly  performing 
insured transactions also depend on market conditions, including 
the  perception  of  AAC’s  creditworthiness,  the  structure  of  the 
underlying  risk  and  associated  policy  as  well  as  other 
counterparty specific factors.  AAC's ability to commute policies 
or purchase certain investments may also be limited by available 
liquidity.

The Segregated Account

In March 2010, AAC established a Segregated Account pursuant 
to  Wisc.  Stat.  §611.24  (2)  (the  “Segregated  Account”)  to 
segregate  certain  segments  of  AAC’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.  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 
  Policy  obligations  not  allocated  to  the 
June  12,  2014. 
Segregated Account remained in the General Account of AAC, 
and  such  policies  in  the  General  Account  were  not  subject  to 
and,  therefore,  were  not  directly  impacted  by  the  Segregated 
Account Rehabilitation Plan.

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"), 

In exchange for an effective consideration package of 40% cash, 
41% Secured Notes (as defined below) and 12.5% AAC's 5.1%  
surplus notes due 2020 ("senior surplus notes"), paid in respect 
of  outstanding  Deferred  Amounts  and  senior  surplus  notes.  
AAC  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 $3,857;

• Cancellation of $552 in principal amount outstanding, plus 
accrued  and  unpaid  interest  of  $257  thereon,  of  senior 
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 senior surplus notes.

AFG  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.    AFG  did  not 
participate in the voluntary surplus note exchange offers.

The Secured Notes

A  newly  formed  special  purpose  entity,  Ambac  LSNI,  LLC 
("Ambac  LSNI")  issued  $2,154  of  new  secured  notes  (the 
“Secured  Notes”),  secured  by  all  assets  of  the  special  purpose 
entity,  which  include  a  note  issued  by  AAC  to  the  special 
purpose entity (the "Ambac Note"), which is secured by a pledge 
of  AAC’s  right,  title  and  interest  in  up  to  the  first  $1,400  of 
proceeds  (net  of  reinsurance)  from  certain  litigations  in  which 
AAC  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 $178 as of December 31, 2020.  AAC also pledged for 
the benefit of the holders of Secured Notes (other than AAC) the 
proceeds of the Secured Notes held by AAC 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,  AFG  and  AAC 
owned securities that were insured by AAC and allocated to the 
Segregated  Account.    As  a  result  of  the  Rehabilitation  Exit 
Transactions,  AFG  and  AAC  received  $125  and  $644, 
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.

Tier 2 Financing

On  the  effective  date  of  the  Rehabilitation  Exit  Transactions, 
AAC  issued  $240  of  senior  notes  (the  “Tier  2  Notes”)  secured 
by  AAC’s  rights,  title  and  interest  in  the  cash  and  non-cash

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

proceeds  (net  of  reinsurance)  above  $1,600  received 
in 
connection  with  the  RMBS  Litigations.  The  indenture  for  the 
Tier 2 Notes limits certain activities of AAC and its subsidiaries, 
such  as  issuing  certain  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

As  part  of  the  Rehabilitation  Exit  Transactions,  AFG  and 
AAC received sufficient consents from holders of senior surplus 
notes  for  a  waiver  and  amendment  (the  "BSA  Waiver  and 
Amendment") of the Settlement Agreement. After giving effect 
to the BSA Waiver and Amendment, the Settlement Agreement 
continues to limit certain activities of AAC 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 
  The  Settlement  Agreement 
includes  certain  allowances  with  respect  to  these  activities  and

Agreement, for consents, waivers or amendments.

limitations). 

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  AFG  and  AAC. 
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.

August 2018 AMPS Exchange

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

On  July  3,  2018,  AFG  and  AAC  commenced  an  offer  to 
exchange  (the  “AMPS  Exchange”)  all  of  AAC’s  outstanding 
AMPS  for  senior  surplus  notes  and,  from  AFG,  cash  and 
warrants  to  purchase  AFG's  common  stock.  The  senior  surplus 
notes  offered  in  the  AMPS  Exchange  have  the  same  terms  as 
other  outstanding  surplus  notes  of  AAC  (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  AMPS  share  (i.e.  $25  thousand  of 
liquidation  preference),  holders  received    senior  surplus  notes  
with  a  total  outstanding  amount  (including  accrued  and  unpaid 
interest  thereon  through  June  22,  2018  (the  "Signing  Date"))

who  tendered  on  or  before  July  17,  2018,  representing  22,096 
shares of the AMPS, also received from AFG $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 
AFG  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 
in 

liquidation  preference  of  $557, 
including  $35 
aggregate liquidation preference in the AFG Purchase;

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

(3)

Issued, in aggregate, $213 in current principal amount of 
senior  surplus  notes  with  accrued  interest  thereon  on 
Settlement  Date  of  $98,  issued  824,307  warrants  and 
paid $11 in cash.

The  AMPS  are  reported  on 
nonredeemable non-controlling interests and are carried at their 
fair  value  at  the  date  AFG  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 2018 for approximately $82.

At  December  31,  2020  and  2019,  AAC  had  5,501  shares  of 
issued  and  outstanding  AMPS  with  a  liquidation  preference  of 
$138 (reported as nonredeemable noncontrolling interest of $60 
on Ambac's balance sheet), respectively. 

2021 Surplus Note Exchanges

On  January  19,  2021,  AAC  entered  into  a  purchase  agreement 
(the  “Purchase  Agreement”)  with  AFG  and  certain  funds  or 
accounts  (the  “Note  Holders”),  pursuant  to  which  (i)  the  Note 
Holders  agreed  to  sell  to  AAC  all  of  the  individual  beneficial 
interests  (the  “Interests”)  in  the  5.1%  senior  notes  due  August 
28,  2039  (the  “Corolla  Notes”),  issued  by  the  Corolla  Trust,  a 
Delaware  statutory  trust  formed  by  AFG  in  2014,  (ii)  AFG  
agreed to sell to AAC the owner trust certificate for the Corolla 
Trust  (the  “Corolla  Certificate”),  which  constituted  all  of  the 
equity  interests  in  the  Corolla  Trust,  and  (iii)  AAC  agreed  to 
exchange  the  Interests  and  the  Corolla  Certificate  for  AAC’s 
the  “Corolla  Note 
(collectively, 
senior 
Exchange”).  The  Note  Holders  held  100%  of  the  outstanding 
Corolla Notes. Pursuant to the Purchase Agreement, each $1.00 
principal  amount  of  the  Corolla  Notes  (and  the  associated 
amount of  accrued and  unpaid interest  thereon) was  exchanged 
for  $0.9125  principal  amount  of  senior  surplus  notes  (and  the 
associated amount of accrued and unpaid interest thereon) on the 
date  of  the  consummation  of  the  Corolla  Note  Exchange  (the 
“Closing”).  In  addition,  every  $1.00  principal  amount  of  the 
Corolla  Certificate  (and  the  associated  amount  of  accrued  and 
unpaid  interest  thereon)  was  exchanged  for  $0.64  principal 
amount  of  senior  surplus  notes  (and  the  associated  amount  of

accrued and unpaid interest thereon) on the date of Closing. The 
Closing  occurred  on  January  22,  2021.  At  the  Closing  AAC 
issued approximately $267 aggregate principal amount of senior 
surplus  notes  to  consummate  the  Corolla  Note  Exchange  and 
acquire  all  of  the  interests  in  the  Corolla  Trust.  Subsequent  to 
the  closing  the  Corolla  Trust  was  dissolved  and  the  junior 
surplus  note  that  had  been  deposited  in  the  Corolla  Trust  by 
AFG in 2014 was canceled.

In  February  2021,  AAC  entered  into  a  purchase  agreement 
pursuant  to  which  the  holder  of  $15  principal  amount  of  5.1% 
junior surplus notes issued by AAC agreed to sell such notes to 
AAC 
in  exchange  for  senior  surplus  notes  (the  "JSN 
Exchange").  Pursuant  to  the  purchase  agreement,  each  $1.00 
principal amount of the junior surplus notes (and the associated 
amount of accrued and unpaid interest  thereon) was  exchanged 
for  $0.8581  principal  amount  of  senior  surplus  notes  (and  the 
associated amount of accrued and unpaid interest thereon). The 
closing  of  the  JSN  Exchange  occurred  on  February  11,  2021 
when  AAC  issued  approximately  $13  aggregate  principal 
amount of senior surplus notes.  Subsequent to the closing of the 
JSN  Exchange  the  junior  surplus  notes  were  canceled.    As  a 
result  of  the  Corolla  Note  Exchange  and  the  JSN  Exchange, 
AAC no longer has any junior surplus notes outstanding.

The  surplus  notes  exchanged  pursuant  to  the  Corolla  Note 
Exchange and the JSN Exchange are part of the same series as, 
and  rank  equally  with,  the  existing  surplus  notes  previously 
issued  by  AAC.  After  giving  effect  to  the  Corolla  Note 
Exchange  and  the  JSN  Exchange,  AAC  has  $853  principal 
amount  of  surplus  notes  outstanding  and  total  principal  and 
accrued  and  unpaid  interest  of  surplus  notes  outstanding  is 
$1,414  as  of  February  11,  2021.  Outstanding  surplus  notes 
principal amount includes $83 owned by AFG, which amount is 
eliminated  in  consolidation  for  purposes  of  US  generally 
accepted accounting principles.

2.  BASIS  OF  PRESENTATION  AND  SIGNIFICANT 

ACCOUNTING POLICIES 

financial  statements 

Ambac’s  consolidated  financial  statements  have  been  prepared 
on  the  basis  of  U.S.  generally  accepted  accounting  principles 
(“GAAP”).  The  preparation  of 
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 
the  valuation 
allowance  on  the  deferred  tax  asset,  any  of  which  individually 
could be material. 

insurance  policies  and 

Consolidation

The  consolidated  financial  statements  include  the  accounts  of 
AFG and all other entities in which AFG (directly or through its 
subsidiaries)  has  a  controlling  financial  interest,  including 
variable  interest  entities  (“VIEs”)  for  which  AFG  or  an  AFG 
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  4.  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. 

AFG Unconsolidated Financial Information

Financial information of AFG is presented in Schedule II to this 
Form 10-K as of December 31, 2020 and 2019 and for the years 
ended  December  31,  2020,  2019  and  2018.  Investments  in 
subsidiaries  are  accounted  for  using  the  equity  method  of 
accounting in Schedule II. 

Measurement  of  Credit  Losses  on  Financial  Instruments 
(CECL)

Instruments 

On  January  1,  2020  Ambac  adopted  ASU  2016-13,  Financial 
Instruments-Credit Losses (Topic 326) - Measurement of Credit 
Losses  on  Financial  Instruments,  subsequently  amended  by 
ASU  2018-19,  Codification  Improvements 
to  Topic  326, 
Financial 
-  Credit  Losses;  ASU  2019-04, 
Codification Improvements to Topic 326, Financial Instruments
—Credit Losses, Topic 815, Derivatives and Hedging, and Topic 
Instruments;  ASU  2019-05,  Financial 
825,  Financial 
Instruments—Credit  Losses  (Topic  326):  Targeted  Transition 
Relief;  and  ASU  2019-11,  Codification  Improvements  to  Topic 
326,  Financial  Instruments  -  Credit  Losses  (collectively  the 
Current Expected Credit Loss standard or "CECL").

The new CECL standard affects how reporting entities measure 
credit losses for financial assets that are not accounted for at fair 
value  through  net  income.  For  Ambac,  these  financial  assets 
include  available-for-sale  debt  securities  and  amortized  cost 
assets, 
reinsurance 
recoverables  and  loans.  CECL  does  not  apply  to  recoveries  of 
previously paid losses on financial guarantee insurance contracts 
accounted for under ASC 944 nor does it apply to equity method 
investments accounted for under ASC 323.

impairments under prior GAAP. The updated guidance was 
applied prospectively.

• For  financial  instruments  measured  at  amortized  cost, 
CECL 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  lifetime  credit  losses.  The  estimate  of  expected 
lifetime 
historical 
information, current information, as well as reasonable and 
supportable  forecasts.  Expected  lifetime  credit  losses  for 
amortized cost assets will be recorded as an allowance for 
credit losses, with subsequent increases or decreases in the 
allowance reflected in net income each period. The updated 
guidance was applied by a cumulative effect adjustment to 
the  opening  balance  of  retained  earnings  at  January  1, 
2020. This adjustment was not material to retained earnings 
or  any  individual  balance  sheet  line  item.    Refer  to  the 
discussion below for each asset type. 

consider 

As a result of adopting CECL, management revised its policies 
and procedures around the credit impairment evaluation process. 
CECL  also  introduced  new  disclosures  related  to  the  credit 
impairment  process, 
including  certain  accounting  policy 
elections that Ambac made under the new standard.  

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 
maturity  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  (Loss)  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 a future term of the security. 
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.  For other fixed maturity 
securities,  such  as  corporate  and  municipal  bonds,  discounts 
were  amortized  or  accreted  over  the  remaining  term  of  the 
securities. 
  Ambac  adopted  ASU  2017-08,  Receivables-
Nonrefundable  Fees  and  Other  Costs  (Subtopic  310-20)  - 
Premium  Amortization  on  Purchased  Callable  Debt  Securities, 
on  January  1,  2019.    ASU  2017-08  shortened  the  amortization 
period for the premium on callable debt securities to the earliest 
call  date.    Under  previous  GAAP,  Ambac  generally  amortized 
the premium over the contractual life (i.e. maturity) of the debt 
security and if that debt security was called, we would record a 
loss equal to the unamortized premium.  

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  and  reported  as  Other  investments  on  the  Consolidated 
Balance  Sheet  with  income  reported  through  Net  investment 
income  on  the  Statement  of  Total  Comprehensive  Income 
(Loss).  Equity  interests  in  the  form  of  common  stock  or  in-
substance common stock are classified as trading securities and 
reported  at  fair  value  while  limited  partner  interests  in  such 
funds are reported using the equity method.

Fair  value 
is  based  primarily  on  quotes  obtained  from 
independent  market  sources.  When  quotes  for  fixed  maturity 
reasonably 
securities  are  not  available  or  cannot  be 
corroborated,  valuation  models  are  used  to  estimate  fair  value. 
These  models  include  estimates,  made  by  management,  which 
utilize  current  market  information.    When  fair  value  is  not 
the 
readily  determinable 
investments  are  valued  using  net  asset  value  ("NAV")  as  a 
practical  expedient  as  permitted  under 
the  Fair  Value 
Measurement  Topic  of  the  ASC.    Investment  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.

funds, 

VIE  investments  in  fixed  maturity  securities  are  carried  at  fair 
value as they are either considered as available for sale securities 
the  fair  value  option  election.  For  additional 
or  under 
information  about  VIE  investments,  including  fair  value  by 
asset-type, see Note 4. Variable Interest Entities. 

Ambac has a formal credit impairment review process for fixed 
maturity available-for-sale securities in its investment portfolio. 
Ambac conducts a review each quarter to identify and evaluate 
investments  that  have  indications  of  impairment  in  accordance 
with the Investments - Debt Securities Topic of the ASC. 

• Prior  to  the  adoption  of  CECL,  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)  whether  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 
believed  a  decline  in  the  fair  value  of  a  particular 
investment is not credit-related, we recorded the decline as 
an  unrealized  loss  net  of  tax  in  Accumulated  Other 
Comprehensive  Income  (Loss)  in  Stockholders’  Equity  on 
our Consolidated Balance Sheets. If it was determined that 
a credit impairment existed, the credit impairment loss was 
recognized  in  earnings,  and  the  other-than-temporary 
amount related to all other factors was recognized in other 
comprehensive  income.  For  fixed  maturity  securities  that 
have credit impairments in a period, the previous amortized

(Dollar Amounts in Millions, Except Share Amounts)

cost of the security less the amount of the credit 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. 

• Under  CECL,  credit  losses  are  evaluated  and  measured 
similarly,  however  the  recognition  of  credit  impairment 
losses for available-for-sale debt securities are recorded as 
an  allowance  for  credit  losses  with  an  offsetting  charge  to 
net  income,  rather  than  as  a  direct  write-down  of  the 
security  as  was  required  under  prior  GAAP.  As  a  result, 
improvements  to  estimated  credit  losses  for  available-for-
sale  debt  securities  are  recognized  immediately  in  net 
income 
time. 
Furthermore,  as  required  under  CECL,  Ambac  no  longer 
considers  the  length  of  time  a  security  has  continuously 
been in an unrealized loss in the credit impairment process.

rather 

If  we  believe  a  decline  in  the  fair  value  of  a  particular 
investment  is  not  credit  impaired,  we  record  the  decline  as  an 
unrealized loss net of tax in Accumulated Other Comprehensive 
Income  (Loss)  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  
impairment charge is recognized in earnings, with the amortized 
cost of the security being written-down to fair value. 

impairment 

The  evaluation  of  securities  for  credit

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 
risks  and 
in  current  period  earnings.  The 
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  AAC  claim  payments.  Ambac’s 
assessment  about  whether  a  decline  in  value  is  considered  a 
credit  impairment  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.

Ambac  has  made  certain  accounting  policy  elections  related  to 
accrued 
interest  receivable  ("AIR")  for  available-for-sale 
investments  under  CECL,  which  are  consistent  with  past 
practices under prior GAAP.  Elections include: i) not measuring 
AIR  for  credit  impairment,  instead    AIR  is  written  off  when  it 
becomes  90  days  past  due;  ii)  writing  off  AIR  by  reversing 
interest income; iii)  presenting AIR separately in Other Assets 
on the balance sheet and iv) excluding AIR from amortized cost 
balances  in  required  CECL  disclosures  found  in  Note  11. 
Investments.  AIR at December 31, 2020 was $10.

Gross premiums were received either upfront or in installments. 
For  premiums  received  upfront,  an  unearned  premium  revenue

transactions,  a  premium  receivable  asset  and  offsetting  UPR

“contractual” method) or (ii) if the underlying insured obligation 
is  a  homogenous  pool  of  assets  which  are  contractually

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,  2020  and  2019,  was  2.2%.  and  2.4%,

• For  financial  guarantee  contracts,  the  issuer's  ability  and 
willingness  to  pay  its  insured  debt  obligation  impacts  the 
payment of policy losses by Ambac as well as the receipt of 
premiums from the issuer.  As such, management leverages 
its  existing  loss  reserve  estimation  process  to  evaluate 
credit impairment for premium receivables. Key factors in 
assessing  credit  impairment  include  historical  premium 
collection  data,  internal  risk  classifications,  credit  ratings 
and  loss  severities.  For  structured  finance  transactions 
involving  special  purpose  entities,  we  further  evaluate  the

the  adoption  of  CECL,  Ambac  assessed 
collectability  of  premium  receivables  in  accordance  with 
ASC  944  and  recorded  an  allowance  for  uncollectible 
premiums.

• Under CECL, management utilizes either a discounted cash 
flow  ("DCF")  or  probability  of  default/loss  given  default 
("PD/LGD")  approach  to  estimate  credit  impairment.    The 
DCF  approach  utilizes  expected  cash  flows  developed  by 
Ambac's  Risk  Management  Group  using  the  same  (or 
similar)  models  used  for  estimating  loss  reserves  where 
such  models  can  identify  shortfalls  in  premiums.  Credit 
impairment  using  the  DCF  approach  is  equal  to  the 
difference between amortized cost and the present value of 
expected cash flows. Credit impairment under the PD/LGD 
approach  is  the  product  of  (i)  the  premium  receivable 
carrying value, (ii) internally developed default probability 
(considering  internal  ratings  and  average  life),  and  (iii) 
internally developed loss severities. 

Refer  to  Note  8.  Financial  Guarantee  Insurance  Contracts  for 
further credit impairment disclosures.  

AAC  has  reinsurance  in  place  pursuant  to  surplus  share  treaty 
and  facultative  reinsurance  agreements.  Similar 
to  gross 
premiums,  premiums  ceded  to  reinsurers  were  paid  either 
upfront or in installments. For premiums paid upfront, a deferred 
ceded premium asset was established which is initially recorded 
as  the  cash  amount  paid.  For  installment  premiums,  a  ceded 
premiums  payable 
liability  and  offsetting  deferred  ceded 
premium asset were 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 
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 

transactions,  we  offset 

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  not  held  by  consolidated  VIEs  are  reported  at  their 
outstanding  principal  balance  less  unamortized  discount 
and  are  reported  within  Other  assets  on  the  Consolidated 
Balance Sheet. 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. Under CECL, 
Ambac  has  a  formal  quarterly  credit  impairment  review 
process for these loans.  The key factors in assessing credit 
impairment  are  internal  credit  ratings  and  loss  severities. 
Management  utilizes  a  PD/LGD  approach,  similar  to  the 
one  described  above  for  premium  receivables,  which  is 
applied to the loan carrying value.

• 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  (Loss).    Such  loans  are  reported  as  Loans,  at  fair 
value  within  the  Variable  interest  entity  assets  section  of 
the Consolidated Balance Sheet.

Derivative Contracts

The  Company  has  entered  into  derivative  contracts  to  hedge 
certain  economic  risks  inherent  in  its  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 interest rate swaps and 
futures contracts.   

• 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.    While  this  portfolio  also  includes

(Dollar Amounts in Millions, Except Share Amounts)

certain  legacy  interest  rate  swaps  executed  in  connection 
with  financial  guarantee  client  financings,  the  interest  rate 
derivatives    portfolio  is  managed  on  the  basis  of  its  net 
sensitivity to changes in interest rates.  Changes in the fair 
value  of  these  interest  rate  derivatives  are  recorded,  along 
with  changes  in  fair  value  of  Ambac's  remaining  credit 
derivatives,  within  Net  gains  (losses)  on  derivative 
contracts  on 
the  Consolidated  Statements  of  Total 
Comprehensive Income (Loss). 

• 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 
(Loss). 

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  12.  Derivative  Instruments  for  further  discussion  of  the 
Company’s use of derivative instruments and their impact of the 
consolidated financial statements. Refer to Note 10. Fair Value 
Measurements for further description of the methodologies used 
to  determine  the  fair  value  of  derivative  contracts,  including 
model inputs and assumptions where applicable. 

Goodwill 

including 

identifiable 

Goodwill  of  $46  is  attributable  to  the  Xchange  acquisition, 
further  discussed 
in  Note  3.  Business  Combination  and 
represents the acquisition cost in excess of the fair value of net 
assets  acquired, 
intangible  assets. 
Goodwill  is  assigned  at  acquisition  to  the  applicable  reporting 
unit of the acquired entity giving rise to the goodwill. Goodwill 
is  not  amortized  but  is  subject  to  impairment  testing.  Goodwill 
impairment  tests  are  performed  annually  or  more  frequently  if 
circumstances indicate a possible impairment. If, after assessing 
qualitative  factors,  management  believes  it  is  more  likely  than 
not that the fair value of a reporting unit is less than its carrying 
amount, a quantitative impairment evaluation is performed. The 
quantitative  goodwill  test  compares  the  estimated  fair  value  of 
the  reporting  unit  with  its  carrying  value  (including  goodwill 
and identifiable intangible assets).  An impairment is recognized 
for the excess of the carrying amount of the reporting unit over it 
estimated  fair  value.  If  the  reporting  unit’s  estimated  fair  value 
exceeds its carrying value, goodwill is not impaired.

As the Xchange acquisition occurred on December 31, 2020 no 
goodwill impairment evaluation was performed in 2020.

Intangible Assets

Financial Guarantee Insurance intangible:

Upon  Ambac's  emergence  from  bankruptcy  in  2013,  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 carrying value is $373 
at  December  31,  2020  and  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. 

Acquired intangible assets:

Ambac acquired $36 of identifiable intangible assets attributable 
to the Xchange acquisition, further discussed in Note 3. Business 
Combination.  The  intangible  assets  are  primarily  related  to 
distribution  relationships,  non-compete  agreements  and  trade 
names, all of which have finite lives and are amortized over their 
estimated useful lives  using the straight-line method. 

The  Company  tests  finite-lived  acquired  intangible  assets  for 
impairment  if  certain  events  occur  or  circumstances  change 
indicating  that  the  carrying  amount  of  the  intangible  asset  may 
not be recoverable. To the extent the carrying value of an asset 
or  asset  group  exceeds  the  projected  undiscounted  cash  flows 
expected to result from the use and eventual disposal of the asset 
or asset group, the Company determines the asset or asset group 
is  impaired  and  records  an  impairment  equal  to  the  difference 
between  the  estimated  fair  value  and  the  carrying  value  of  the 
asset  or  asset  group.  In  addition,  we  will  recognize  an 
impairment  prior  to  the  sale  of  an  asset  or  asset  group  if  the 
carrying value of the asset or asset group exceeds its estimated 
fair value.

As  the  Xchange  acquisition  occurred  on  December  31,  2020, 
there  was  no  amortization  expense  nor  any  impairment  of  the 
intangible assets in 2020.

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 (i) consolidated variable interest entity 
cash  restricted  to  support  the  obligations  of  the  consolidated 
VIEs,  (ii)  cash  held  by  AAC  received  from  its  investment  in 
Secured Notes and pledged for the benefit of holders of Secured 
Notes (other than AAC) and (iii) fiduciary cash held by Xchange 
described below.

Fiduciary  Assets  and  Liabilities:  In  Xchange's  capacity  as  a 
managing  general  agent,  generally  it  collects  premiums  from 
insureds  and  remits  the  premiums  to  the  respective  insurance 
carriers, net of  fees to other parties, including  its  commissions. 
Xchange also collects claims or refunds from carriers on behalf 
insurance  premiums  and  claims 
of 

insureds.  Unremitted

proceeds  are  held  by  Xchange  in  a  fiduciary  capacity.    Since 
fiduciary  assets  are  not  available  for  corporate  use,  they  are 
shown  in  the  consolidated  balance  sheets  as  an  offset  to 
fiduciary liabilities, which are reported in Other liabilities.

Restricted cash for net uncollected premiums and claims and the 
related fiduciary liabilities were $4 at December 31, 2020. 

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 based upon the present value ("PV") of expected net 
claim  cash  outflows  or  expected  net  recovery  cash  inflows, 
discounted  at  risk-free  rates.    The  estimate  for  future  net  cash 
flows consider the likelihood of all possible outcomes that may 
occur  from  missed  principal  and/or  interest  payments  on  the 
insured obligation. This estimate also considers future recoveries 
related to breaches of contractual representations and warranties 
by  RMBS  transaction  sponsors,  remediation  strategies,  excess 
spread  and  other  contractual  or  subrogation-related  cash  flows. 
Ambac’s  approach  to  resolving  disputes  involving  contractual 
breaches  by  transaction  sponsors  or  other  third  parties  has 
included negotiations and/or pursuing litigation. Ambac does not 
estimate  recoveries  for  litigations  where  its  sole  claim  is  for 
fraudulent  inducement,  since  any  remedies  under  such  claims 
would be non-contractual. 

• Net  claim  cash  outflow  policies  represent  contracts  where 
the PV of expected cash outflows are greater than the PV of 
expected recovery cash inflows. For such policies, a “Loss 
and  loss  expense  reserves”  liability  is  recorded  for  the 
excess of the PV of expected net claim cash outflows over 
the unearned premium revenue. 

• Net recovery cash inflow policies represent contracts where 
the PV of expected recovery cash inflows are greater than 
the PV of expected claim cash outflows. For such policies, 
a “Subrogation recoverable” asset is recorded.

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  from  period  to  period  and  update  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 

student 

(for  collateral  dependent 
loan 

adversely classified credit rating includes the deterioration of an 
issuer’s financial condition, underperformance of the underlying 
transactions  such  as 
collateral 
securitizations),  poor 
mortgage-backed  or 
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 
efforts  could  cause  an  increase  in  the  delinquency  and  the 
potential for 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 the fundamental 
credit  quality.  Through  ongoing  surveillance,  Ambac  may  also 
designate  Class  I  credits  into  one  or  more  of  the  following 
categories:

• 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 
financial  and  economic 
sustainability.

the  overall 

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.

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

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  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 potential 
for additional remediation activities (e.g., commutations). 

The second approach entails the use of cash-flow based models 
to  estimate  expected  losses  (future  claims,  net  of  potential 

recoveries,  expected  to  be  paid  to  the  holder  of  the  insured 
financial  obligation).  Ambac’s  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  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  loss  estimate  is  developed  based 
on  assigning  probabilities  to  multiple  claim  payment  scenarios 
and  applying  an  appropriate  discount  factor.  Additionally,  we 
assign a probability to the issuer’s ability to refinance an insured 
issue,  Ambac’s  ability  to  execute  a  potential  settlement  (i.e., 
commutation)  of  the  insurance  policy,  including  the  impact  on 
restructuring 
future 
installment  premiums,  and/or  other 
scenarios.  The  commutation  scenarios  and 
related 
the 
probabilities  of  occurrence  vary  by  transaction,  depending  on 
our view of the likelihood of negotiating such a transaction with 
issuers and/or investors. 

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. 

Below we provide further details of our loss reserve models for 
both RMBS and student loan exposures:

RMBS Expected Loss Estimate

insured  RMBS 

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

loan, second-lien loans may carry a significantly higher severity 
in the event of a loss, approaching or exceeding 100%. 

(i) 

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: 
the 
loans'  characteristics  and  status, 
transaction’s  underlying 
(“HPA”) 
appreciation 
price 
home 
projected 
(ii) 
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.    Observed  servicer-level  behavior  may  also  have  an 
impact on projected 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.    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 the base, upside and downside scenarios. 

to 

revisions 

On  a  monthly  basis,  we  compare  monthly  claims  submitted 
against  the  trustees’  reports,  waterfall  projections  and  our 
understanding  of  the  transactions’  structures  to  identify  and 
resolve  discrepancies.  We  also  review  the  vendor’s  published 
waterfall 
identify  significant  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.  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. 

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.

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 
  representations  and 
warranties  with  respect  to  loan  characteristics,  the  absence  of 
loan  pools  and  other 
borrower  fraud 
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 
significant  mortgage 
counsel  engaged  consultants  with 
underwriting 
underwriting 
to 
documentation  for  mortgage  loans  underlying  certain  insured 
transactions  which  exhibited  exceptionally  poor 
RMBS 
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 
representations  and  warranties,  we  submitted  nonconforming 
loans for repurchase to the contractual counterparty bearing the 
repurchase obligation, typically the transaction sponsor. 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  securitization. 
Specifically,  the  repurchase  price  is  paid  by  the  sponsor  to  the 
securitization  trust  which  holds  the  loan.  The  cash  becomes  an 
asset of the trust, replacing the loan that was repurchased by the 
sponsor.  On  a  monthly  basis,  the  cash  received  related  to  loan 
repurchases  by  the  sponsor  is  aggregated  with  cash  collections 
from  the  underlying  mortgages  and  applied  in  accordance  with 
the  trust  indenture  payment  waterfall.  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 
lawsuits  seeking 
compliance with the repurchase obligations in the securitization 
documents.

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  AAC  to  honor  its  financial 
obligations;  the  initiation  of  rehabilitation  proceedings  against 
AAC; decreased likelihood of AAC delivering value to Ambac, 
through  dividends  or  otherwise;  and  a  significant  drop  in  the 
value of securities issued and/or insured by Ambac or AAC.

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 
litigation  outcomes, 
views  on  ultimate  settlement  and/or 
(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 
these  probability-weighted

The  student 
insured  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 
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.  For  the 
liabilities  of  the  transaction  which  we  insure,  the  transaction 
losses are then incorporated into a waterfall tool to develop loss

estimates  for  our  exposures  in  various  base,  upside  and 
downside scenarios. 

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

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 
(Loss).    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 (Loss).  

For  long-term  debt  issued  by  consolidated  VIEs  in  which 
Ambac's  variable  interest  arises  from  financial  guarantees 
written  by  Ambac's  subsidiaries  ("FG  VIEs"),  we  may  elect  to 
use  the  fair  value  option  on  an  instrument  by  instrument  basis. 
When the fair value option is elected, changes in the fair value 
of the FG VIEs' long-term debt is reported within Income (loss) 
on  variable  interest  entities  in  the  Consolidated  Statements  of 
Total  Comprehensive  Income  (Loss),  except  for  the  portion  of 
the  total  change  in  fair  value  of  financial  liabilities  caused  by 
changes in the instrument-specific credit risk which is presented 
separately  in  Other  comprehensive  income  (loss).    In  cases 
where  the  fair  value  option  has  not  been  elected,  the  FG  VIEs' 
long-term debt is carried at par less unamortized discount, with 
interest  expense  reported  within  Income  (loss)  on  variable 
interest  entities  in  the  Consolidated  Statements  of  Total 
Comprehensive Income (Loss).

Noncontrolling Interests

Nonredeemable noncontrolling interests

At  December  31,  2020  and  2019,  AAC  had  5,501  shares  of 
issued  and  outstanding  AMPS  with  a  liquidation  preference  of 
$138 (reported as nonredeemable noncontrolling interest of $60 
on  Ambac's  balance  sheet).    The  auction  occurs  every  28  days 
and  the  dividend  rate  has  continuously  been  reset  at  the 
maximum rate of one-month LIBOR plus 200 basis points. 

Under the terms of the AMPS, dividends may not be paid on the 
common stock of AAC 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  AFG  (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.    AAC  has  not 
paid dividends on its AMPS since 2010.

Redeemable noncontrolling interests

The Xchange acquisition, further described in Note 3. Business 
Combination, resulted in 80% ownership of the acquired entities

Ambac  has  a  call  option  to  purchase  the  remaining  20%  from 
the  minority  owners  (i.e.,  noncontrolling  interests)    and  the 
minority owners have a put option to sell the remaining 20% to

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 
to  expense  based  on  actuarial 
established  and  charged 
determinations.  

Incentive Compensation

Incentive compensation is a key component of our compensation 
strategy.  Incentive  compensation  has  two  components:  short 
term  incentive  compensation  (consisting  of  an  annual  cash 
bonus  and,  prior  to  2020,  awards  of  deferred  stock  units  for 
certain officers) and long term incentive plan awards (consisting 
of deferred cash and awards of 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 the prior year's performance for the Company, the employee 
and the employee's business unit.  

In  2020,  the  Ambac  2013  Incentive  Compensation  Plan  (the 
“2013  Incentive  Plan”)  was  superseded  by  the  2020  Incentive 
Compensation  Plan  ("2020  Incentive  Plan").    Both  plans  allow 
for  the  granting  of  stock  options,  restricted  stock,  stock 
appreciation  rights,  restricted  and  performance  units  and  other 
awards  to  employees,  directors  and  consultants  that  are  valued 
or  determined  by  reference  to  Ambac's  common  stock.    Under 
these  plans,  Ambac  has  issued  both  cash  and  equity  awards  to 
US employees. 

In connection with the adoption of the 2020 Incentive Plan, all 
shares reserved but unissued under the 2013 Incentive Plan were 
transferred  to  the  the  2020  Incentive  Plan  in  addition  to  any 
shares  underlying  outstanding  awards  under  the  2013  Incentive 
Plan  as  of  June  2,  2020  that  subsequently  terminate  by 
expiration or forfeiture, cancellation, or otherwise are not issued.  

Under the 2013 and 2020 Incentive Compensation Plans. Ambac 
recognizes  compensation  costs  for  all  equity  classified  awards 
granted  at  fair  value,  which  is  measured  on  the  grant  date,  and 
records  forfeitures  for  unvested  shares  only  when  they  occur. 
For  awards 
include  service  and  performance 
conditions, the fair value is the market price of Ambac stock on 
the grant date. For awards that also contain a market condition, 
specifically a total shareholder return ("TSR") modifier, the fair 
value is estimated using a Monte Carlo simulation.

that  only 

The types of equity 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 require both future service 
and achieving specified performance targets to vest. Certain 
performance  stock  unit  grants  also  include  a  market 
condition  TSR  modifier  that  will  cause  the  total  payout  at 
the  end  the  performance  period  to  increase  or  decrease 
depending on Ambac's stock performance relative to a peer 
group. Compensation costs for all performance stock units 
are  only  recognized  when 
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

the  achievement  of 

In  2015,  Ambac  UK's  Board  of  Directors  adopted  a  long  term 
incentive  plan  which  provided  cash  based  performance  awards 
to  Ambac  UK  employees.  Since  all  performance  conditions 
under  this  plan  were  met,  the  Ambac  UK  Board  of  Directors 
adopted  a  new  long  term  incentive  plan  for  Ambac  UK 
employees  in  2020,  which  includes  both  performance  and  time 
based  awards.  Compensation  costs  for  all  performance  based 
awards  are  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. 
Compensation  costs  for  time-based  awards  are  recognized 
evenly over the service period.  

Operating Leases

In  2019,  Ambac  adopted  ASU  2016-02,  Leases  (Topic  842), 
amended by ASU 2018-01, Land Easement Practical Expedient; 
ASU  2018-10,  Codification Improvements to Topic 842; ASU  
2018-11,  Targeted  Improvements;  ASU    2018-20,  Narrow-
Scope  Improvements  for  Lessors;  and  ASU  2019-01,  Leases 
(Topic  842):  Codification  Improvements  (collectively    the  
"New  Lease    Standard").  Ambac  used  a  modified  retrospective 
approach  and  applied  the  New  Lease  Standard  on  its  effective 
date of January 1,  2019. Additionally,  Ambac  applied the  New 
Lease Standard to its recently acquired affiliate, Xchange, on the 
acquisition  date  of  December  31,  2020.  Refer  to  Note  3. 
Business Combination for further discussion of the acquisition.

A contract contains a lease if it conveys the right to control the 
use  of  identified  property,  plant,  or  equipment  for  a  period  of 
time  in  exchange  for  consideration.    Ambac's  evaluation  of 
whether  certain  contracts  contain  leases  requires  judgment 
regarding what party controls the asset and whether the asset is 
physically distinct.

Ambac  is  the  lessee  in  leases  which  are  classified  as  operating 
leases.  In  accordance  with  the  New  Lease  Standard,  Ambac 
recognizes  a  single  lease  cost,  calculated  so  that  the  cost  is 
allocated  generally  on  a  straight-line  basis  over  the  lease  term 
within  operating  expenses  in  the  Consolidated  Statements  of

term 
commences  on  the  earlier  of  the  date  when  we  become  legally 
obligated  for  the  rent  payments  or  the  date  on  which  we  take 
possession  of  the  property.  For  such    operating  leases,  Ambac 
recognizes  a  right-of-use  ("ROU")  asset  and  a  lease  liability, 
initially measured at the present value of the lease payments, on 
the later of the adoption date or lease commencement date.  The 
discount rate used to initially measure the ROU assets and lease 
liabilities  reflects  the  estimated  secured  borrowing  rate  of  the 
applicable  Ambac  subsidiary,  which  considers  the  rate  of 
existing  or  recent  debt  obligations  of  the  entity.  All  cash 
payments  are  classified  within  operating  activities  in  the 
statement of cash flows. 

For  contracts  where  Ambac  is  the  lessee,  we  have  elected  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.  For  all  contracts 
where  Ambac  is  the  lessee  and  lessor  we  have  also  elected  the 
practical  expedient 
lease  and  non-lease 
to  not  separate

Depreciation and Amortization

Depreciation  of  furniture  and  fixtures,  certain  information 
technology  development  costs  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

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  July  2020,  United  Kingdom  legislation 
increasing the tax rate from 17% to 19% was fully enacted. As 
such, we incorporated the effects of the tax rate increase in our 
current and deferred tax evaluation for the year ended December 
31, 2020.  

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

The  level  of  deferred  tax  asset  recognition  is  influenced  by 
management’s assessment of future profitability, which depends 
on  the  existence  of  sufficient  taxable  income  within  the  carry 
forward periods available under the tax law. 

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 
(together,  "Basic  Weighted  Average  Shares 
Outstanding").  Diluted  net  income  per  share  is  computed  by 
dividing net income attributable to common stockholders by the 
Basic  Weighted-Average  Shares  Outstanding  plus  all  potential 
dilutive  common  shares  outstanding  during  the  period.    All 
potential dilutive common shares outstanding consider common 
stock  deliverable  pursuant  to  warrants,  vested  and  unvested 
options,  unvested  restricted  stock  units  and  performance  stock 
units granted under existing compensation plans. 

Reclassifications and Rounding

Reclassifications may have been made to prior years' amounts to 
conform to the current year's presentation.  Certain amounts and 
tables  in  the  consolidated  financial  statements  and  associated 
notes may not add due to rounding.

Adopted Accounting Standards

Effective  January  1,  2020,  Ambac  adopted  the  following 
accounting standards:

CECL

For  further  discussion  of  CECL,  refer  to  the  Measurement  of 
Credit Losses (CECL), Investments, Net Premiums, Loans, and 
in  Note  2.  Basis  of 
Loss  and  Loss  Expenses  sections 
Presentation  and  Significant  Accounting  Policies;  Note  8. 
Financial  Guarantee 
Insurance  Contracts;  and  Note  11. 
Investments  in  the  Notes  to  Consolidated  Financial  Statements 
included in this Annual Report on Form 10-K for the year ended 
December 31, 2020.

For available-for-sale debt securities, the updated guidance was 
applied prospectively and for financial instruments measured at 
amortized cost (i.e. premiums receivable, loans and reinsurance 
recoverables), 
the  updated  guidance  was  applied  by  a 
cumulative effect adjustment to the opening balance of retained 
earnings at January 1, 2020. This adjustment was not material to 
retained earnings or any individual balance sheet line item.

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

that  were 

• 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  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  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.

Disclosure  amendments  related  to  changes  in  unrealized  gains 
and  losses  included  in  other  comprehensive  income  (loss)  for 
Level  3  instruments,  the  range  and  weighted  average  of 
significant unobservable inputs, and the narrative description of 
measurement  uncertainty  were  applied  prospectively  only  for 
the  most  recent  interim  or  annual  period  presented.    All  other 
disclosure  amendments  were  applied  retrospectively  to  all 
periods presented. 

Refer  to  Note  10.  Fair  Value  Measurements  for  further 
disclosures.

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

AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES

(Dollar Amounts in Millions, Except Share Amounts)

rather than as a direct interest in its entirety (as was previously 
required  under  prior  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.  
Adoption  of  this  ASU  did  not  impact  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 
the 
capitalization  of  certain  costs 
application  development  stage.  That  guidance  also  requires 
entities to expense costs during the preliminary project and post-
implementation  stages  as  they  are  incurred.  Adoption  of  this 
ASU did not impact Ambac's financial statements.

incurred  only  during 

Effective  December  31,  2020,  Ambac  adopted  the  following 
accounting standard:

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 have been removed are 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.  Adoption  of 
this  ASU  only  affected  disclosures  and  did  not  have  an  impact 
on Ambac's financial statements.  

Future Application of Accounting Standards:

Reference Rate Reform

to  ease 

In March 2020, the FASB issued ASU 2020-04, Reference Rate 
Reform  (Topic  848)  -  Facilitation  of  the  Effects  of  Reference 
Rate  Reform  on  Financial  Reporting.    The  ASU  provides 
companies  with  optional  guidance 
the  potential 
accounting  burden  related  to  transitioning  away  from  reference 
rates, such as LIBOR, that are expected to be discontinued as a 
result  of  initiatives  undertaken  by  various  jurisdictions  around 
the  world.  For  example,  under  current  GAAP,  contract 
modifications  which  change  a  reference  rate  are  required  to  be 
evaluated in determining whether the modifications result in the 
establishment  of  new  contracts  or  the  continuation  of  existing 
contracts.  The  amendments  in  this  ASU  provide  optional 
expedients  and  exceptions  for  applying  GAAP  to  contracts, 
hedging  relationships,  and  other 
transactions  affected  by 
reference rate reform if certain criteria are met.  The ASU can be 
applied  prospectively  as  of  the  beginning  of  the  interim  period 
that includes March 12, 2020, (January 1, 2020 for calendar year 

companies) or any date thereafter, but does not apply to contract 
modifications  and  other  transactions  entered  into  or  evaluated 
after  December  31,  2022.    Management  has  not  determined  
when  it  will  adopt  this  ASU,  and  the  impact  on  Ambac's 
financial statements is being evaluated.

3.   BUSINESS COMBINATION

On  December  31,  2020,  Ambac  completed  the  acquisition  of 
80%  of  the  membership  interests  of  Xchange  for  a  purchase 
price  of  $81  in  cash.    Xchange,  whose  management  principals 
retained the remaining 20% is a property and casualty Managing 
General  Underwriter  ("MGU"),  specializing  in  accident  and 
health insurance. Since its inception in 2010, Xchange's business 
has  been  supported  by  major  insurers,  reinsurers,  third  party 
administrators, brokers and producers. 

The  acquisition  has  been  accounted  for  as  a  business 
combination  and  advances  Ambac's  strategy  of  expanding  into 
the    MGU  and  Managing  General  Agent  ("MGA")  sectors.  
Based  on  the  acquisition  date  and  the  complexity  of  the 
underlying  valuation  work,  certain  amounts  included  in  the 
Company's  Consolidated  Financial  Statements  may  be 
provisional  and  thus  subject  to  further  adjustments  within  the 
permitted measurement period as defined by ASC 805.  

The  following  table  summarizes  the  consideration  paid  for 
Xchange  and  the  estimated  fair  values  of  the  aggregate  assets 
and  liabilities  acquired,  as  well  as  the  fair  value  of  the 
noncontrolling interest, at the acquisition date:

Goodwill  was 
the  excess  purchase 
consideration over net assets acquired and primarily consists of  
the future economic benefits that we expect to receive as a result 
of  the  acquisition,  driven  by  the  value  of  Xchange's  potential 
future  distribution  and  carrier  relationships,  and  synergies  with 
other  Ambac  business  operations.  Goodwill  that  is  expected  to 
be deductible for tax purposes amounts to approximately $36.   

The  fair  values  assigned  to  tangible  and  identifiable  intangible 
assets  acquired  and 
liabilities  assumed  are  based  on 
management’s  estimates  and  assumptions  at  the  time  of 
acquisition and is subject to updating as more detailed analyses 
are completed and additional information about the fair value of 
assets acquired and liabilities assumed becomes available.  

The  fair  value  of  the  redeemable  non-controlling  interest  of  $7 
was estimated based on the non-controlling interest’s respective

financial  protection 

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 
to  Ambac.  Generally,  upon 
certain 
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.  Under the 2018 Stipulation and Order,  
AAC  is  required  to  obtain  OCI  approval  with  respect  to  the 
exercise  of  certain  significant  control  rights  in  connection  with 
policies  that  had  previously  been  allocated  to  the  Segregated 
Account.    Accordingly,  AAC  does  not  have  the  right  to  direct 
the most significant activities of those FG VIEs.

• 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  consolidates  certain  FG 
VIEs  in  cases  where  we  also  have  the  power  to  direct  the

(i) the transaction experiencing deterioration and breaching 
performance triggers, giving Ambac the ability to exercise 
certain  control  rights,  (ii)    Ambac  being  involved  in  the 
design  of  the  VIE  and  receiving  control  rights  from  its 
inception,  such  as  may  occur  from  loss  remediation 
activities,  or  (iii)  the  transaction  is  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. 

Because  the  acquisition  occurred  on  last  day  of  the  reporting 
period, there were no revenues or earnings of Xchange included 
in  Ambac's  Consolidated  Statement  of  Comprehensive  Income 
for the period ended December 31, 2020.

Pro  forma  information  related  to  the  acquisition  has  not  been

financial results.

4.   VARIABLE INTEREST ENTITIES

Ambac,  with  its  subsidiaries,  has  engaged  in  transactions  with 
variable interest entities ("VIEs") in various capacities. 

• A  VIE  is  deconsolidated  in  the  period  that  Ambac  no 
longer  has  such  control  rights,  which  could  occur  in

value  option  for  consolidated  FG  VIE  financial  assets  and 
financial  liabilities,  except  in  cases  where  Ambac  was 
involved in the design of the VIE and was granted control 
rights at its inception. 

◦ When the fair value option is elected, changes in the fair 
value of the FG VIE's financial assets and liabilities are 
reported within Income (loss) on variable interest entities 
in  the  Consolidated  Statements  of  Total  Comprehensive 
Income (Loss), except for the portion of the total change 
in fair value of financial liabilities caused by changes in 
the  instrument-specific  credit  risk  which  is  presented 
separately in Other comprehensive income (loss).

◦ In cases where the fair value option has not been elected, 
the FG VIE's invested assets are fixed maturity securities 
and  are  considered  available-for-sale  as  defined  by  the 
Investments - Debt Securities Topic of the ASC.  These 
assets  are  reported  in  the  financial  statements  at  fair 
value  with  unrealized  gains  and  losses  reflected  in 
Accumulated  Other  Comprehensive  Income  (loss)  in 
Stockholders'  Equity.      The  financial  liabilities  of  these 
FG  VIEs  consist  of  long  term  debt  obligations  and  are 
carried  at  par  less  unamortized  discount.    Income  from 
the  FG  VIE's  available-for-sale  securities  (including 
investment  income,  realized  gains  and  losses  and  credit 
impairments as applicable) and interest expense on long 
term  debt  are  reported  within  Income  (loss)  on  variable 
interest  entities  in  the  Consolidated  Statements  of  Total 
Comprehensive Income (Loss). 

• Upon initial consolidation of a FG VIE, Ambac recognizes 
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,  Ambac 
recognizes 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 
from  consolidation  and 
deconsolidation  that  are  reported  in  earnings  are  reported 
within  Income  (loss)  on  variable  interest  entities  on  the 
Consolidated  Statements  of  Total  Comprehensive  Income 
(Loss).

losses 

• 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 — 
the  ASC.  Consequently,  upon 
Insurance  Topic  of 
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 
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  associated  debt  and 
investment balances are eliminated upon consolidation.

ceded  premium, 

subrogation 

FG  VIEs  which  are  consolidated  may  include  non-recourse 
assets  or  liabilities.  FG  VIEs'  liabilities  (and  in  some  cases 
assets)  that  are  insured  by  the  Company  are  with  recourse, 
because  the  Company  guarantees  the  payment  of  principal  and 
interest  in  the  event  the  issuer  defaults.  FG  VIEs'  assets  and 
liabilities  that  are  not  insured  by  the  Company  are  without 
recourse,  because  Ambac  has  not  issued  a  financial  guarantee 
and  is  under  no  obligation  for  the  payment  of  principal  and 
interest  of  these  instruments.    Therefore,  the  Company’s 
economic  exposure  to  consolidated  FG  VIEs  is  limited  to  the 
financial guarantees issued for recourse assets and liabilities and 
any  additional  variable  interests  held  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  consolidated  FG  VIEs 
are attributable to Ambac’s interests through financial guarantee 
premium and loss payments with the VIE.

As further discussed in Note 8. Financial Guarantee Insurance Contracts, on February 12, 2019, in connection with the COFINA POA, the 
COFINA Class 2 Trust was established.  Ambac was required to consolidate the COFINA Class 2 Trust, which resulted in a gain of $15.  
The 2019 balance sheet impact of this additional VIE on the date of consolidation was an increase to total consolidated assets and liabilities 
by $292 and $364, respectively.  Ambac deconsolidated one, one and four VIEs for the years ended December 31, 2020, 2019 and 2018, 
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,  and  resulted  in  the  gain  (loss)  on 
deconsolidation noted in the above table.  The 2020 balance sheet impact of the deconsolidation was a decline in total consolidated assets 
and liabilities by $0 and $0 from December 31, 2019 to December 31, 2020.

(1) Maximum exposure to loss represents the maximum future payments of principal and interest on insured obligations and derivative contracts.  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 included in “Premium receivables” and “Subrogation recoverable” for financial guarantee insurance contracts on 
Ambac’s Consolidated Balance Sheets.

Insurance liabilities represent the amount included in “Loss and loss expense reserves” and “Unearned premiums” for financial guarantee insurance 
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

Ambac Sponsored Non-consolidated VIEs

In  1994,  Ambac  established  a  VIE  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 
incurred.  
guarantee  policies  with  respect 
Ambac  does  not  consolidate  this  entity  because  the  exercise  of 
related  control  rights  in  such  policies  remain  subject  to  OCI 
approval  under  the  Stipulation  and  Order,  as  discussed  above. 
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.    At  December  31,  2020  and  2019 

indebtedness 

to 

the  fair  value  of  this  entity  was  $1  and  $3,  respectively,  and  is 
reported  within  Other  assets  on  the  Consolidated  Balance 
Sheets.

• Total  principal  amount  of  debt  outstanding  was  $410  and 
$403  at  December  31,  2020  and  2019,  respectively.    In 
each  case,  Ambac  sold  assets  to  this  entity,  which  are 
composed  of  utility  obligations  with  a  weighted  average 
rating  of  BBB+  at  December  31,  2020,  and  weighted 
average  life  of  0.2  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,  2020,  AAC  had 
financial guarantee insurance policies issued for all assets, 
MTNs  and  derivative  contracts  owned  and  outstanding  by 
the entity.

• Insurance premiums paid to AAC 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 AAC by depositing the junior 
surplus note into the Corolla Trust, a VIE, in exchange for cash 
and the Corolla Certificate, which represented 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 the Corolla Certificate as an equity 
investment  within  Other  investments  on  the  Consolidated 
Balance Sheets with associated results from operations included 
within  Net  investment  income  (loss):  Other  investments  on  the

(Loss).  The equity investment had a carrying value of $51 and 
$46 as of December 31, 2020 and 2019, respectively.  As further 
described  in  Note  1.  Background  and  Business  Description,  on 
January  22,  2021,  AAC  completed  the  Corolla  Note  Exchange 
transaction  whereby  it  acquired  100%  of  the  outstanding 
obligations of the Corolla trust and the owner trust certificate in 
exchange for AAC surplus notes.  

On  February  12,  2018,  Ambac  formed  a  VIE,  Ambac  LSNI, 
LLC  ("Ambac  LSNI").  Ambac  LSNI  issued  Secured  Notes  in 
connection  with  the  Rehabilitation  Exit  Transactions.    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  Maturity  Securities  in  the  Consolidated 
Balance  Sheets.  The  carrying  value  of  Secured  Notes  held  by 
Ambac was $465 and $535 as of December 31, 2020 and 2019, 
respectively.    Ambac's  debt  obligation  to  the  VIE  (the  Ambac 
Note)  had  a  carrying  value  of  $1,641  and  $1,763  at 
December  31,  2020  and  2019,  respectively,  and  is  reported

6.   NET INCOME PER SHARE 

As of December 31, 2020, 45,809,139 shares of AFG's common 
stock (par value $0.01) and warrants entitling holders to acquire 
up  to  4,877,749  shares  of  new  common  stock  at  an  exercise 
price of $16.67 per share were outstanding.  For the three years 
ended  December  31,  2020,  2019  and  2018,  34,  0  and  194 
warrants were exercised, respectively, resulting in an issuance of 
8, — and 194 shares of common stock, respectively.

On June 30, 2015, the Board of Directors of AFG authorized the 
establishment of a warrant repurchase program that permits the 
repurchase of up to $10 of warrants.  On November 3, 2016, the 
Board  of  Directors  of  AFG  authorized  a  $10  increase  to  the 
warrant repurchase program.  For the years ended December 31, 
2020  and  2019,  AFG  did  not  repurchase  any  warrants.    As  of 
December 31, 2020, AFG had repurchased 985,331 warrants at a 
total  cost  of  $8  (average  cost  of  $8.21  per  warrant).    The 
remaining  aggregate  authorization  at  December  31,  2020  was 
$12.    In  connection  with  the  AMPS  Exchange,  AFG  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

(1) For the years ended December 31, 2020 and 2019 , Ambac had 
a  net  loss  and  accordingly  excluded  all  potentially  dilutive 
securities from the determination of diluted loss per share as their 
impact was anti-dilutive.

Credit Impairment for Premium Receivables:

Management evaluates premium receivables for expected credit 
losses  ("credit  impairment")  in  accordance  with  the  CECL 
standard adopted January 1, 2020, which is further described in 
Note  2.  Basis  of  Presentation  and  Significant  Accounting 
Policies.  Management's  evaluation  of  credit  impairment  under 
prior  GAAP  rules  was  not  materially  different.  Most  credit 
impairment  disclosures  below  were  only  made  prospectively 
from  the  CECL  adoption  date  as  they  were  not  required 
previously under GAAP. 

As  further  discussed  in  Note  2.  Basis  of  Presentation  and 
Significant  Accounting  Policies,  the  key  indicator  management 
uses  to  assess  the  credit  quality  of  premium  receivables  is 
Ambac's  internal  risk  classifications  for  the  insured  obligation 
determined by the Risk Management Group.

For 2020, the adverse development in prior years was primarily 
a result of deterioration in Public Finance credits, including the 
impact of lower discount rates, as discussed below in the 
section, "Puerto Rico", partially offset by positive development 
in the RMBS portfolio, including the benefit of lower discount 
rates.  

For 2019, the adverse development in prior years was primarily 
a  result  of  deterioration  in  Public  Finance  credits,  primarily 
Puerto Rico, partially offset by the benefit for (i) the Ballantyne 
Re plc ("Ballantyne") and Puerto Rico COFINA commutations, 
and  (ii)  positive  development  in  the  RMBS  and  Student  Loan 
portfolios.

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.

COVID-19:

In March 2020, the outbreak of COVID-19 pandemic, caused by 
a novel strain of the coronavirus, was recognized as a pandemic 
by  the  World  Health  Organization,  and  the  outbreak  is 
widespread  globally,  including  in  the  markets  in  which  we 
operate. The COVID-19 outbreak had, and continues to have, a 
notable  impact  on  general  economic  conditions,  including  but 
not  limited  to  higher  unemployment;  volatility  in  the  capital 
markets;  closure  or  severe  curtailment  of  the  operations  and, 
hence,  revenues,  of  many  businesses  and  public  and  private 
enterprises to which we are directly or indirectly exposed, such 
as hotels, restaurants, sports and entertainment facilities, airports 
and  other  transportation  facilities,  and  retail  establishments, 
mostly  due  to  social  distancing  guidelines,  travel  bans  and 
restrictions, and business restrictions and shutdowns. 

COVID-19  has  adversely  impacted  Ambac's  financial  position 
and  results  of  operations  as  credit  risk  in  the  insured  and 

investment  portfolios  has  increased.    In  the  insured  portfolio, 
municipal,  mortgage-backed,  student  loan  and  other  asset 
securitization exposures could be materially adversely impacted, 
and  as  a  result,  with  the  exception  of  the  mortgage-backed 
sector, we increased loss reserves across each of these and other 
sectors  during  the  year  ended  December  31,  2020.  In  the 
mortgage-backed  sector,  significantly  lower  interest  rates  have 
increased  excess  spread  levels  and  largely  offset  the  impact  of 
higher  mortgage  delinquencies  and  projected  losses  resulting 
from the COVID-19 pandemic. 

In the U.S., significant monetary policy actions, fiscal stimulus 
measures and other relief measures have helped to moderate the 
economic  impact  of  COVID-19.  These  measures  include 
monetary  policy  decisions,  such  as  quantitative  easing, 
providing  liquidity  to  financial  institutions,  providing  liquidity 
to  credit  markets,  the  Paycheck  Protection  Program  Lending 
Facility  and  the  Main  Street  Business  Lending  Program;

Congressional actions, such as the Coronavirus Aid, Relief and 
Economic  Security  ("CARES")  Act,  the  Paycheck  Protection 
Program  And  Health  Care  Enactment  Act,  the  Families  First 
Coronavirus  Response  Act,  and,  most  recently,  the  2021 
Consolidated  Appropriations  Act,  which,  among  other  things, 
provides  direct  payments  to  households,  support  for  small 
businesses,  renter  assistance  and  funding  for  transport,  airlines, 
education and state and local governments. In addition, housing 
measures,  such  as  forbearance  on  mortgages  and  suspension  of 
foreclosures  and  evictions,  and  various  executive  orders  have 
helped  to  provide  relief.  Outside  of  the  US,  and  in  the  United 
Kingdom  and  Italy  in  particular,  where  Ambac  has  insured 
portfolio  exposure,  various  monetary  policy,  fiscal  stimulus 
measures  and  other  actions  have  helped  to  moderate  the 
economic impact.  

We  are  continuously  evaluating  and  updating  our  view  of  the 
macro economic environment as well as our specific credit view 
of  each  of  our  insured  exposures  considering  the  significant 
uncertainties  brought  upon  us  by  the  COVID-19  pandemic.  
Accordingly,  our  loss  reserves  may  be  under-estimated  as  a 
result  of  the  ultimate  scope,  duration  and  magnitude  of  the 
effects of COVID-19 pandemic.

Puerto Rico

its 

Ambac has exposure to the Commonwealth of Puerto Rico (the 
instrumentalities  across  several 
"Commonwealth")  and 
different  issuing  entities  with  total  net  par  exposure  of  $1,070. 
Components  of  Puerto  Rico  net  par  outstanding  include  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. Each issuing entity has 
its  own  credit  risk  profile  attributable  to  discrete  revenue 
sources,  direct  general  obligation  pledges  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  AAC.    AAC  may  be  required  to  make  significant 
amounts  of  policy  payments  over  the  next  several  years,  the 
recoverability  of  which  is  subject  to  great  uncertainty,  which 
may  lead  to  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  variability  in 
tax  revenues, 
economic  growth  and  demographic 
changes in law or the effects thereof,  essential services expense, 
federal 
funding  of  Commonwealth  needs,  as  well  as 
interpretation  of  legislation,  legal  documents,  and  updated 
financial  information  (when  available).  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;  and  the  trajectory  of  recovery  from 
the  COVID-19  pandemic  and  related  economic  downturn.  The 
longer-term  recovery  of  the  Commonwealth  economy  and  its 
essential infrastructure will likely be dependent on, among other 
factors, 
the  management,  usage  and  efficacy  of  federal 
resources. 

trends, 

Also  important  to  Puerto  Rico's  economic  growth,  government 
reform and creditor outcomes is the Commonwealth Fiscal Plan, 

inform 

certified by the Financial Oversight and Management Board for 
Puerto  Rico  ("Oversight  Board")  on  May  27,  2020.  The 
Commonwealth Fiscal Plan purports to incorporate the impact of 
COVID-19  on  the  Commonwealth  economy,  and  projects 
diminished  growth,  budget  surplus,  and  debt  capacity  as 
compared  to  previous  versions  of  the  Commonwealth  Fiscal 
Plan.  This  is  due  to  the  Oversight  Board’s  projected  impact  of 
COVID-19  on  the  Puerto  Rico  economy  and  tax  collections  as 
well as related general uncertainty on the economic outlook. The 
Commonwealth  Fiscal  Plan  will  significantly 
the 
Commonwealth  Plan  of  Adjustment  in  the  Commonwealth's 
Title III proceeding, and the diminished economic performance 
described in the new Commonwealth Fiscal Plan implies worse 
outcomes than had been previously disclosed for creditors under 
the  Commonwealth  Plan  of  Adjustment.  However,  as  was  the 
case  with  previous  versions  of  the  Commonwealth  Fiscal  Plan, 
the  current  version  of  the  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 AAC's claims development potential, risk 
profile  and  long-term  financial  strength.  According  to  a  letter 
sent  January  19,  2021,  from  the  Oversight  Board's  Executive 
Director,  Natalie  Jaresko,  to  Governor  Pedro  Pierluisi  and 
legislative  leaders,  the  Oversight  Board  expects  to  certify  an 
updated Commonwealth Fiscal Plan by April 23, 2021.

Substantial  uncertainty  exists  with  respect  to  the  ultimate 
outcome  for  creditors  in  Puerto  Rico,  such  as  AAC,  due  to, 
among  other  matters,  the  Commonwealth  Plan  of  Adjustment 
and changes that are anticipated to be made thereto to reflect the 
terms  of  the  Second  Amended  PSA;  political  uncertainty  and 
leadership  turnover;  legislation  enacted  by  the  Commonwealth 
and  the  federal  government,  including  PROMESA;  and  actions 
taken pursuant to such laws, including Title III filings. AAC 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 differences among the credits 
insured by AAC may not be respected.

AAC  has  participated  and  may  continue  to  participate  in 
mediation  related  to  potential  debt  restructurings.  Mediation 
may  not  be  productive  or  may  not  resolve  AAC's  claims  in  a 
manner  that  avoids  significant  losses.  No  assurances  can  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 
negotiated transaction debt restructuring, definitive agreement or 
plans  of  adjustment  will  be  approved  by  the  court  and 
completed,  or  that  any  transaction  or  plans  of  adjustment  will 
not  have  an  adverse  impact  on  Ambac's  financial  condition  or 
results. It is possible that certain restructuring process solutions, 
together  with  associated  legislation,  budgetary,  and/or  public 
policy proposals could be adopted and could further impair our 
exposures,  causing  losses  that  could  have  a  material  adverse 
impact on our results of operations and financial condition.

reflecting 

While  our  reserving  scenarios  account  for  a  wide  range  of 
possible  outcomes, 
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 
residual  effects  emanating  from 
the  damage  caused  by 
hurricanes  Maria  and  Irma  in  2017,  the  earthquakes  that  began 
in  late  December  2019,  and  COVID-19  our  loss  reserves  may 
ultimately  prove  to  be  insufficient  to  cover  our  losses, 
potentially  having  a  material  adverse  effect  on  our  results  of 
operations and financial position, 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, 2020, Ambac had incurred losses associated with 
its  Domestic  Public  Finance  insured  portfolio  of  $256,  which 
was  primarily  impacted  by  the  continued  uncertainty  and 
volatility of the situation in Puerto Rico as well as a decline in 
the  rate  used  to  discount  reserves.  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,  given  the  circumstances 
described  herein.    Such  additional  losses  may  have  a  material 
adverse  effect  on  Ambac’s  results  of  operations  and  financial 
condition  and  may  result  in  adverse  consequences  such  as 
impairing the ability of AAC to honor its financial obligations; 
the 
initiation  of  rehabilitation  proceedings  against  AAC; 
decreased  likelihood  of  AAC  delivering  value  to  Ambac, 
through  dividends  or  otherwise;  and  a  significant  drop  in  the 
value  of  securities  issued  or  insured  by  Ambac  or  AAC.    For 
public  finance  credits,  including  Puerto  Rico,  as  well  as  other 
issuers,  for  which  Ambac  has  an  estimate  of  expected  loss  at 
December 31, 2020, the possible increase in loss reserves under 
stress  or  other  adverse  conditions  and  circumstances  was 
estimated to be approximately $1,200  This possible increase in 
loss  reserves  under  stress  or  other  adverse  conditions  is  very 
significant and if we were to experience such incremental losses, 
our  stockholders’  equity  as  of  December  31,  2020,  would 
decrease  from  $1,140  to  $(60).    However,  there  can  be  no 
assurance that losses may not exceed such amount.

COFINA Debt Restructuring

On  February  4,  2019,  the  COFINA  Plan  of  Adjustment 
("COFINA POA") was confirmed and the Commonwealth 9019 
motion was approved by the U.S. District Court for the District 
of Puerto Rico. On February 12, 2019, the COFINA POA went 
effective.  Pursuant to the POA, all existing COFINA senior and 
subordinate bonds were discharged and exchanged for cash and 
new  COFINA  current  interest  and  capital  appreciation  bonds 
("new  COFINA  bonds").  The  cash  and  new  COFINA  bonds 
allocated to COFINA 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). 

As a result of the COFINA POA, and subsequent commutations, 
amendments,  and  redemptions  of  obligations  of  the  COFINA 
Class 2 Trust, AAC's net par outstanding was reduced to $80 as 
of  December  31,  2020.  AAC's  remaining  policy  obligation  of 

$80  net  par  is  an  asset  of  the  COFINA  Class  2  Trust,  which 
holds a ratable distribution of new COFINA bonds, the interest 
and  principal  from  which  can  be  used  to  partially  offset 
Ambac’s remaining insurance liability.  As further discussed in 
Note  4.  Variable  Interest  Entities,  AAC  consolidates  the 
COFINA Class 2 Trust.

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

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. 

Ambac  has  recorded  RMBS  R&W  subrogation  recoveries  of 
$1,751,  ($1,725  net  of  reinsurance)  and  $1,727,  ($1,702  net  of 
reinsurance) at December 31, 2020 and 2019, respectively.

performance, changes in the creditworthiness of a sponsor and the 
projected timing of recoveries. 

Ceded Reinsurance

AAC  has  reinsurance  in  place  pursuant  to  surplus  share  treaty 
and facultative reinsurance agreements. The reinsurance of risk 
does not relieve AAC of its original liability to its policyholders. 
In  the  event  that  any  of  AAC’s  reinsurers  are  unable  to  meet 
their  obligations  under  reinsurance  contracts,  AAC  would, 
nonetheless, be liable to its policyholders for the full amount of 
its policy. 

AAC’s  reinsurance  assets,  including  deferred  ceded  premiums 
and  reinsurance  recoverables  on  losses  amounted  to  $103  at 
December  31,  2020.  Credit  exposure  existed  at  December  31, 
2020, with respect to reinsurance recoverables to the extent that 
any reinsurer may not be able to reimburse AAC under the terms 
of these reinsurance arrangements. At December 31, 2020, there 
were  ceded  reinsurance  balances  payable  of  $27  offsetting  this 
credit exposure. 

To  minimize  its  credit  exposure  to  losses  from  reinsurer 
insolvencies,  AAC  (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 AAC 
in the event of rating agency downgrades of a reinsurer (among

Credit Impairment for Reinsurance Recoverables:

Management  evaluates  reinsurance  recoverables  for  expected 
credit losses ("credit impairment") in accordance with the CECL 
standard adopted January 1, 2020, which is further described in 
Note  2.  Basis  of  Presentation  and  Significant  Accounting 
Policies.  Management's  evaluation  of  credit  impairment  under 
prior  GAAP  rules  was  not  materially  different.  Most  credit 
impairment  disclosures  below  were  only  made  prospectively 
from  the  CECL  adoption  date  as  they  were  not  required 
previously under GAAP. 

The key indicator management uses to assess the credit quality 
of reinsurance recoverables is collateral posted by the reinsurers 
and independent rating agency credit ratings. For the majority of 
reinsurance contracts where Ambac has recorded a recoverable, 
the  fair  value  of  collateral  posted  by  the  reinsurer  to  AAC 
exceeds  AAC's  reinsurance  recoverable  carrying  value,  net  of 
ceded  premiums  payable.  AAC  has  credit  exposure  of    $1  and 
has  recorded  an  allowance  for  credit  losses  of  $0  at  December 
31,  2020.    The  calculation  of  the  allowance  excludes  deferred 
ceded premiums as it is a non-monetary asset.

The insurance intangible asset and accumulated amortization are 
included in the Consolidated Balance Sheets, as shown below.

(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.  

(2)  The weighted-average amortizations period is 7.5 years.

9.   INSURANCE REGULATORY RESTRICTIONS 

United States

AAC  is  domiciled  in  the  State  of  Wisconsin  and,  as  such,  it  is 
subject  to  the  insurance  laws  and  regulations  of  the  State  of 
Wisconsin  (the  “Wisconsin  Insurance  Laws”)  and  is  regulated 
by the OCI. Everspan Indemnity Insurance Company ("Everspan 
Indemnity")  and 
its  wholly  owned  subsidiary,  Everspan 
Insurance  Company  ("Everspan  Insurance"  and,  together  with 
Everspan Indemnity, "Everspan" or the “Everspan Group”), are 
domiciled in Arizona and are subject to the insurance laws and 
regulations  of  Arizona  (the  “Arizona  Insurance  Laws”  and 
together  with  the  Wisconsin  Insurance  Laws,  the  “State 
Insurance  Laws”).  Everspan  is  regulated  by  the  Arizona 
Department of Insurance and Financial Institutions (“DIFI”). In 
addition,  both  Ambac  Assurance  and  Everspan  Insurance  are 
subject  to  the  insurance  laws  and  regulations  of  the  other 
jurisdictions in which they are licensed. 

Insurance  laws  and  regulations  applicable  to  insurers  vary  by 
jurisdiction, but the insurance laws and regulations applicable to 
our  insurance  carriers  generally  require  them  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,  corporate  governance  and  enterprise  risk. 
Regulated  insurance  companies  are  also  required  to  file 
quarterly  and  annual  statutory  financial  statements  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-

(Dollar Amounts in Millions, Except Share Amounts)

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” (or meets a similar standard) 
in the opinion of the regulator. 

The  domiciliary  regulators  of  Ambac  Assurance  and  Everspan, 
OCI  and  DIFI,  respectively,  have  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  financial  examinations  by, 
respectively,  the  OCI  and  DIFI.  The  State  Insurance  Laws 
require  regulated  insurance  companies  to  maintain  minimum 
standards  of  business  conduct,  maintain  minimum  surplus  to 
policyholders,  meet  certain  financial  tests,  and  file  certain 
reports, including information concerning their capital structure, 
ownership,  financial  condition,  corporate  governance  and 
enterprise  risk.  The  State  Insurance  Laws  also  require  prior 
approval by OCI and DIFI, respectively, of certain transactions 
between  AAC  or  Everspan,  respectively,  and  their  affiliates.  
Ambac Assurance, because it is a financial guarantee insurer is 
not subject to risk-based capital requirements. 

In  December  2020,  Everspan  Insurance  completed  its  re-
domestication  from  Wisconsin  to  Arizona  and  obtained  broad 
authority  to  write  property  and  casualty  insurance  (while 
contemporaneously  surrendering  its  authority  to  write  financial 
guaranty  insurance)  in  Arizona.  Everspan  Insurance  is  seeking 
similar  amendments  to  its  certificates  of  authority  in  all  other 
states.    Everspan  Insurance  is  subject  to  risk-based  capital 
requirements.

Everspan  Indemnity  was  formed  in  2020  as  a  domestic  surplus 
lines  insurer  in  Arizona  and,  accordingly,  is  eligible  to  write 
property  and  casualty  insurance  as  an  excess  and  surplus  lines 
insurer  in  all  states  by  virtue  of  the  U.S.  Nonadmitted  and 
Reinsurance Reform Act of 2010. Everspan Indemnity is subject 
to risk-based capital requirements.  Neither Everspan Insurance 
nor Everspan Indemnity has yet issued any new policies.

Ambac  Assurance  and  Everspan  are  in  compliance  with  the 
minimum  capital  and  surplus  levels  required  under  the  State 
Insurance Laws required to transact all business written to date. 

is  subject 

Xchange,  like  other  managing  general  agents  and  program 
administrators, 
licensing  requirements  and 
to 
regulation  by  insurance  regulators  in  various  states  in  which 
they  conduct  business.  Every  state  and  Washington,  D.C.  have 
enacted a version of the NAIC Model Managing General Agents 
Act,  which  governs  licensing  and  the  relationship  between 
insurers and managing general agents.

In  addition  to  the  legal  restrictions  applicable  to  AAC  as 
described  herein,  pursuant  to  the  terms  of  the  Settlement 
Agreement, the Stipulation and Order and the indenture for the 
Tier 2 Notes, AAC 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 
the  operations  of  AAC.  The  Settlement 
which  restrict 

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. 

Although  not  domiciled  in  New  York,  AAC  is  nevertheless 
subject  to  the  New  York  insurance  law  governing  financial 
insurers.  New  York’s  comprehensive  financial 
guarantee 
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  AAC.  The  New  York  financial  guarantee  insurance 
law also establishes single and aggregate risk 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 
limits,  policyholders’  surplus  and  contingency 
aggregate 
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, 2020, AAC is in compliance with 
applicable  aggregate  risk  limits  but  not  in  compliance  with 
applicable  single  risk  limits.  Through  run-off  of  the  portfolio, 
AAC  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.  

The financial statements of AAC and Everspan are prepared on 
the basis of accounting practices prescribed or permitted by the 
State  Insurance  Laws  and  OCI  and  DIFI  actions  thereunder. 
AAC  and  Everspan  use  such  statutory  accounting  practices 
prescribed  or  permitted  by  the  OCI  and  DIFI,  respectively,  for 
determining and reporting their financial condition and results of 
operations,  including  for  determining  solvency  under  the  State 
Insurance Laws. Both Wisconsin and Arizona have adopted the 
National  Association  of  Insurance  Commissioners  (“NAIC”) 
accounting practices and procedures manual (“NAIC SAP”) as a 
component  of  prescribed  practices  as  codified  in  each  state’s 
applicable law or regulation.  

Statutory  policyholder  surplus  differs  from  stockholder's  equity 
determined under GAAP principally due to statutory accounting 
rules  that  treat  financial  guarantee  premiums  and  loss  reserves, 
investments,  consolidation  of  subsidiaries  or  variable  interest 
entities and surplus notes differently.

• AAC’s  statutory  policyholder  surplus  was  $865  at 
December 31, 2020, as compared to $1,088 as of December 
31, 2019. 

• Everspan  Indemnity  has  statutory  policyholder  surplus  of 
$26 as of December 31, 2020. At December 31, 2020, there 
were  no  significant  differences  from  stockholder's  equity 
under GAAP.

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

Additionally,  the  OCI  has  prescribed  additional  practices  and 
has  permitted  accounting  practices  for  AAC.  As  a  result  of  the 
prescribed  and  permitted  practices  discussed  below,  AAC’s 
statutory surplus at December 31, 2020 and 2019 was higher by 
$40  and  lower  by  $12,  respectively,  than  if  AAC  had  reported 
such amounts in accordance with NAIC SAP. 

Everspan does not have any prescribed or permitted practices at 
December 31, 2020 or December 31, 2019.  

Prescribed Accounting Practices

OCI has prescribed the following accounting practices that differ 
from NAIC SAP for AAC:  

• 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”,  AAC  records  probable 
losses  on  its  subsidiaries  for  which  it  guarantees  their 
obligations.  AAC  also  discounts  probable 
losses  on 
guarantees  of  subsidiary  obligations  using  a  discount  rate 
equal  to  the  average  rate  of  return  on  its  admitted  assets.  
AAC’s  average  rates  of  return  on  its  admitted  assets  at 
December  31,  2020  and  2019  were  4.56%  and  5.43%, 
respectively. OCI has directed AAC 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 ("OTTI") has occurred, the amount of the 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 AAC 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  AAC  continues  to  maintain 
statutory loss reserves without adjustment for the economic 
investment 
effects  of 
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.

Permitted Accounting Practices

OCI has allowed the following permitted practice for AAC: 

• 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.  AAC  received  permission 
from  OCI  to  record  contributions  to  and  releases  from  the 
contingency reserve, in accordance with NAIC SAP. 

United Kingdom

in 

the  United  Kingdom,  with 

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 
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,  until  December  31,  2020,  the  regulatory 
regime in the United Kingdom must have complied with certain 
EU legislation binding on all EU member states. 

These regulators have exercised significant oversight of Ambac 
UK  since  2008,  after  Ambac,  AAC  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 (until December 31, 2020) to do the same 
through  a  branch  in  Milan,  Italy,  and  a  number  of  other 
European  Union  (“EU”)  countries.  Until  December  31,  2020, 
EU  legislation  had  allowed  Ambac  UK  to  conduct  business  in 
EU  states  other 
through  a 
“passporting”  arrangement,  which  eliminated  the  necessity  of 
those  other  EU 
additional 
jurisdictions.  These  passporting  arrangements  ended  on 
December  31,  2020,  when  the  U.K.’s  Brexit  transitional 
arrangements with the EU ended.  Ambac UK closed its Milan 
branch  and  transferred  it's  remaining  policy  to  the  United 
Kingdom in December 2020.  Ambac UK's remaining policies in 
the  EU  were  either  commuted  or  the  benefits  of  those  policies

were  transferred  to  United  Kingdom  entities  in  advance  of 
December 31, 2020.

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, 
its 
and  dialogue  between  Ambac  UK  management  and 
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  AAC,  it  has  been  unable  to  pay 
ordinary dividends to AFG since 2008 and will be unable to pay 
common dividends in 2021 without the prior consent of the OCI, 
which  is  unlikely.    AAC’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. AAC is not expected to make dividend 
payments to AFG for the foreseeable future.

Everspan does not have sufficient earned surplus at this time to 
pay ordinary dividends under the Arizona Insurance Laws.

Subject to the foregoing, pursuant to the State Insurance Laws, 
AAC  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  solvency,  surplus  and  asset  tests. 
Board  action  authorizing  a  shareholder  distribution  by  AAC 
(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.  Everspan  similarly  must  report  to  the  DIFI  all  dividends 
and other distributions to shareholders within five business days 
following their declaration and at least ten business days before 
payment of the dividend or distribution.

In  addition,  Wisconsin  Insurance  Laws  restrict  the  payment  of 
extraordinary  dividends,  which  is  any  distribution  which, 
together with distributions in the prior 12 months, is greater than 
the  lesser  of  (a)  10%  of  policyholders’  surplus  as  of  the 
preceding  December  31,  and  (b)  the  greater  of  (i)  statutory  net 
income  (loss)  for  the  calendar  year  preceding  the  date  of  the 
dividend,  minus  realized  capital  gains  for  that  calendar  year  or 
(ii)  the  aggregate  of  statutory  net  income  (loss)  for  three 
calendar years preceding the date of the dividend, minus realized 
capital gains for those calendar years and minus dividends paid 
or  credited  within  the  first  two  of  the  three  preceding  calendar 
years.  Extraordinary dividends must be reported to OCI at least 
30 days prior to payment and are subject to  disapproval  by  the 
OCI.

Arizona 
the  payment  of 
extraordinary  dividends,  which  is  any  dividend  or  distribution 
which together with other dividends or distributions made within 
the  preceding  twelve  months  exceeds  the  lesser  of  (a)  10%  of 
policyholders’ surplus as of the preceding December 31 and (b) 
the net income for the twelve month period ending the preceding 
December 31. Extraordinary dividends must be reported to DIFI 
at least 30 days prior to payment, during which period DIFI may 
disapprove or approve such payment.

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 AAC 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  AAC  and  Ambac  UK).  Ambac  UK  is  not  expected  to 
pay any dividends to AAC for the foreseeable future.

Pursuant to the Settlement Agreement, AAC may not make any 
“Restricted  Payment”  (which  includes  dividends  from  AAC  to 
Ambac) in excess of $5 in the aggregate per annum, other than 
Restricted Payments from AAC to Ambac in an amount up to $8 
per  annum  solely  to  pay  operating  expenses  of  Ambac. 
Concurrent with making any such Restricted Payment, a pro rata 
amount of AAC'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 AAC’s AMPS, dividends may not be paid on 
the  common  stock  of  AAC  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 
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

10.   FAIR VALUE MEASUREMENTS 

The  Fair  Value  Measurement  Topic  of  the  ASC  establishes  a  framework  for  measuring  fair  value  and  disclosures  about  fair  value 
measurements.

Fair Value Hierarchy

The Fair Value Measurement Topic of the ASC specifies a fair value hierarchy based on whether the inputs to valuation techniques used to 
measure  fair  value  are  observable  or  unobservable.  Observable  inputs  reflect  market  data  obtained  from  independent  sources,  while 
unobservable  inputs  reflect  Company-based  assumptions.  The  fair  value  hierarchy  prioritizes  model  inputs  into  three  broad  levels  as 
follows:

l 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, certain highly liquid pooled fund 
investments, exchange traded futures contracts, variable rate demand obligations and money market funds.

l Level 2

l 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 maturity securities representing 
municipal, asset-backed and corporate obligations, certain interest rate swap contracts and most long-term debt of 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  maturity  securities.  Additionally,  Level  3  assets  and  liabilities  generally 
include loan receivables, and certain long-term debt of variable interest entities consolidated under the Consolidation Topic 
of the ASC.

The  Fair  Value  Measurement  Topic  of  the  ASC  permits,  as  a  practical  expedient,  the  estimation  of  fair  value  of  certain  investments  in 
funds using the net asset value per share of the investment or its equivalent (“NAV”).  Investments in funds valued using NAV are not 
categorized as Level 1, 2 or 3 under the fair value hierarchy.  The following table sets forth the carrying amount and fair value of Ambac’s 
financial assets and liabilities as of December 31, 2020 and 2019, including the level within the fair value hierarchy at which fair value 
measurements are categorized. As required by the Fair Value Measurement Topic of the ASC financial assets and liabilities are classified in 
their entirety based on the lowest level of input that is significant to the fair value measurement.

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

different  third  parties  may  use  different  methodologies  or

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  maturity  securities,  equity 
interests  in  pooled  investment  funds,  derivative  instruments, 
certain variable interest entity assets and liabilities and 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 
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 
control 
financial  management.  Other  valuation 
procedures specific to particular portfolios are described further

the 

Fixed Maturity Securities

The fair values of fixed maturity investment securities are based 
primarily  on  market  prices  received  from  broker  quotes  or 
alternative  pricing  sources.  Because  many  fixed  maturity 
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 maturity 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, 2020, approximately 2%, 95%, and 
3%  of  the  fixed  maturity  investment  portfolio  (excluding 
variable  interest  entity  investments)  was  valued  using  broker 
internal  valuation 
quotes,  alternative  pricing  sources  and 
models, respectively. At December 31, 2019, approximately 4%, 
94%,  and  2%  of  the  fixed  maturity  investment  portfolio 
(excluding variable interest entity investments) was valued using 
broker quotes, alternative pricing sources and internal valuation 
models, respectively. 

Ambac  performs  various  review  and  validation  procedures  to 
quoted  and  modeled  prices  for  fixed  maturity  securities, 
including  price  variance  analyses,  missing  and  static  price 
reviews,  overall  valuation  analysis  by  portfolio  managers  and 
finance  managers  and  reviews  associated  with  our  ongoing 
impairment  analysis.  Unusual  prices  identified  through  these 
procedures  will  be  evaluated  further  against  alternative  third-
party quotes (if available, internally modeled prices and/or other 
relevant data, 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  portfolio  managers  and  finance 
managers. 

Information  about  the  valuation  inputs  for  fixed  maturity 
securities classified as Level 3 is included below:

Other  asset-backed  securities:    This  security  is  a  subordinated 
tranche  of  a  securitization  collateralized  by  Ambac-insured 
military housing bonds.  The fair value classified as Level 3 was 
$78 and $72 at December 31, 2020 and 2019, 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,  2020  and  2019  include  the 
following:

December 31, 2020:

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

b.  Average Life............................................ 14.83 years

c.  Yield......................................................... 10.50%

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

b.  Average Life............................................ 15.58 years

c.  Yield......................................................... 11.75%

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  NAV  as  a  practical  expedient  as 
permitted under the Fair Value Measurement Topic of the ASC.  
Refer to Note 11. Investments for  additional information about 
such investments in pooled funds that are reported at fair value

consolidated VIE equity interest is internally calculated using a 
market 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 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.  
Factors  considered  in  estimating  the  amount  of  any  Ambac 
credit  valuation  adjustment  ("CVA")  on  such  contracts  include 
collateral  posting  provisions, 
the 
counterparty, the period of time remaining on the derivative and 
the pricing of recent terminations.  The aggregate Ambac CVA 
impact reduced the fair value of derivative liabilities by less than 
a million dollars at both  December 31, 2020 and 2019.  

right  of  set-off  with 

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  determination  of  their  fair 
value.

Ambac's 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  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  one  remaining  credit 
derivative with an internal credit rating of AA at December 31, 
2020.  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 marketplace, 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.

Long-term Debt

Long-term  debt  includes  AAC  surplus  notes  and  junior  surplus 
notes,  the  Ambac  Note  and  Tier  2  Notes  issued  in  connection 
with  the  Rehabilitation  Exit  Transactions  and  the  Ambac  UK 
debt  issued  in  connection  with  the  Ballantyne  commutation.  
The  fair  values  of  surplus  notes,  the  Ambac  Note  and  Tier  2 
Notes are classified as Level 2.  The fair value of junior surplus 
notes and Ambac UK debt are classified as Level 3.  

Other Financial Assets and Liabilities

Included in Other assets are Loans and Ambac’s equity interest 
in  an  Ambac  sponsored  VIE  established  to  provide  certain 
their  debt 
financial  guarantee  clients  with  funding  for 
obligations.  The  fair  values  of  these  financial  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  FG  VIEs  consolidated 
under  the  Consolidation  Topic  of  the  ASC  consist  primarily  of 
fixed maturity securities and loans held by the VIEs, derivative 
instruments and notes issued by the VIEs which are reported as 
long-term  debt.  As  described  in  Note  4.  Variable  Interest 
Entities,  these  FG  VIEs  are  securitization  entities  which  have 
liabilities and/or assets guaranteed by AAC or Ambac UK. 

The  fair  values  of  FG  VIE  long-term  debt  are  based  on  price 
quotes  received  from 
independent  market  sources  when 
available.  Such  quotes  are  considered  Level  2  and  generally 
consider a variety of factors, including recent trades of the same 
and similar securities. For those instruments where quotes were 
not  available  or  cannot  be  reasonably  corroborated,  fair  values 
are  based  on  internal  valuation  models.  Comparable  to  the 
sensitivities of investments in fixed maturity 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 FG 
VIE long-term debt.

FG VIE derivative asset and liability fair values are determined 
using  vendor-developed  valuation  models,  which  incorporated 
observable market data related to specific derivative contractual 
terms  including  interest  rates,  foreign  exchange  rates  and  yield 
curves.

The  fair  value  of  FG  VIE  fixed  maturity  securities  and  loan 
assets  are  based  on  Level  2  market  price  quotes  received  from 
independent market sources when available.  Typically, FG VIE 
asset  fair  values  are  not  readily  available  from  market  quotes 
and are estimated internally. Internal valuation of each FG VIE’s 
fixed maturity securities or loan assets are derived from the fair 
values of the notes issued by the respective VIE and the VIE’s

derivatives, determined as described above, adjusted for the fair 
values of Ambac’s financial guarantees associated with the VIE. 
The  fair  value  of  financial  guarantees  consist  of:  (i)    estimated 
future  premium  cash  flows  discounted  at  a  rate  consistent  with 
that  implicit  in  the  fair  value  of  the  VIE’s  liabilities  and  (ii) 
estimates  of  future  claim  payments  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  par-
weighted average rate of 2.4% and 2.7% at December 31, 2020 
and  2019,  respectively.    At  December  31,  2020,  the  range  of 
these discount rates was between 1.8% and 3.9%.

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  2020,  2019  and  2018.  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.

The amount of total gains/(losses) included in earnings attributable to the change in unrealized gains or

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. 
Derivative  instruments  are  transferred  into  Level  3  when  the  use  of  unobservable  inputs  becomes  significant  to  the  overall  valuation.   
Invested  assets  transferred  out  of  Level  3  into  Level  2  in  2018  consisted  of  an  Ambac-insured  re-REMIC  collateralized  by  distressed 
mortgage-backed securities.  There were no other transfers of financial instruments into or out of Level 3 in the periods disclosed.

investments  on 

Ambac’s  non-VIE  invested  assets  are  primarily  comprised  of 
fixed  maturity  securities  classified  as  available-for-sale  and 
interests  in  pooled  investment  funds  which  are  reported  within 
Other 
the  Consolidated  Balance  Sheets.  
Interests  in  pooled  investment  funds  in  the  form  of  common 
stock  or  in-substance  common  stock  are  classified  as  trading 
securities,  while  limited  partner  interests  in  such  funds  are 
reported  using  the  equity  method.    Other  investments  also 
include  equity  interests  held  by  AFG  including  the  equity 
interest  in    Corolla  Trust,  an  unconsolidated  trust  created  in 
connection  with  its  sale  of  Segregated  Account  junior  surplus 
notes  on  August  28,  2014.  As  further  described  in  Note  1. 
Background  and  Business  Description,  on  January  22,  2021,

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

Management  has  determined  that  the  securities  in  the  above 
table  do  not  have  credit  impairment  as  of  December  31,  2020 
and  2019  based  upon  (i)  no  actual  or  expected  principal  and 
interest payment defaults on these securities; (ii) analysis of the 
creditworthiness  of  the  issuer  and  financial  guarantor,  as 
applicable, and (iii) for debt securities that are non-highly rated 
beneficial  interests  in  securitized  financial  assets,  analysis  of 
whether  there  was  an  adverse  change  in  projected  cash  flows. 
Management's evaluation as of December 31, 2020, includes the 
expectation that all principal and interest payments on securities 
guaranteed by AAC  or Ambac UK will be made timely and in 
full.

Ambac’s assessment about whether a security is credit impaired 
reflects  management’s  current  judgment  regarding  facts  and 
circumstances  specific  to  the  security  and  other  factors.  If  that 
judgment  changes,  Ambac  may  record  a  charge  for  credit 
impairment in future periods.

Realized Gains and Losses including Impairments

Ambac  had  zero  allowance  for  credit  losses  at  December  31, 
2020.

Ambac  did  not  purchase  any  financial  assets  with  credit 
deterioration for the year ended December 31, 2020.

Counterparty  Collateral,  Deposits  with  Regulators  and 
Other Restrictions

Ambac  routinely  pledges  and  receives  collateral  related  to 
certain  transactions.    Securities  held  directly  in  Ambac’s 
investment  portfolio  with  a  fair  value  of  $140  and  $85  at 
December  31,  2020  and  2019,  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  maturity  securities 
pledged as collateral, at fair value” and "Short-term investments 
pledged as collateral, at fair value".  Refer to Note 12. Derivative 
Instruments  for  further  information  on  cash  collateral.    There 
was no cash or securities received from other counterparties that 
were re-pledged by Ambac.

Securities carried at $8 and $6 at December 31, 2020 and 2019, 
respectively,  were  deposited  by  Ambac's  insurance  subsidiaries 
with governmental authorities or designated custodian banks as 
required  by  laws  affecting  insurance  companies.      Invested 
assets  carried  at  $1  at  December  31,  2020  were  deposited  as 
security in connection with a letter of credit issued for an office 
lease.

Securities  with  a  fair  value  of  $178  and  $197  at  December  31, 
2020  and  2019,  respectively,  were  pledged  as  collateral  and  as 
sources of funding to repay the Secured Notes issued by Ambac 
LSNI.  The  securities  may  not  be  transferred  or  re-pledged  by 
Ambac LSNI. Collateral may be sold to fund redemptions of the 
Secured Notes. 

AAC  also  pledged  for  the  benefit  of  the  holders  of  Secured 
Notes  (other  than  AAC)  the  proceeds  of  interest  payments  and 
partial  redemptions  of  the  Secured  Notes  held  by  AAC.    The 
amount  of  such  proceeds  held  by  AAC  was  $9  and  $55  at 
December 31, 2020 and 2019 and is included in Restricted cash 
on  the  Consolidated  Balance  Sheet.    AAC  may,  from  time  to 
time, sell all or a portion of the Secured Notes it owns.  In the 
event  that  AAC  sells  any  of  the  Secured  Notes  it  owns,  the 
proceeds  must  be  used  to  redeem  a  like  amount  of  the  Ambac 
Note  at  par.  The  price  at  which  AAC  sells  the  Secured  Notes 
may differ from the price at which it redeems the Secured Notes.

Guaranteed Securities

Ambac’s  fixed  maturity  portfolio  includes  securities  covered  by  guarantees  issued  by  AAC  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 and weighted-average underlying rating of insured securities in Ambac's 
investment portfolio at December 31, 2020 and 2019, respectively:

occurrence  of  a  specific  event  such  as  a  payment  default  or 
bankruptcy 
to  an  underlying  obligation.  Credit 
derivatives  issued  are  insured  by  AAC.  The  outstanding  credit 
derivative  transaction  at  December  31,  2020,  does  not  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.

Our credit derivatives were written on a “pay-as-you-go” basis. 
Similar  to  an  insurance  policy,  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.  The  principal  notional  outstanding 
for  credit  derivative  contracts  was  $257  and  $280  as  of

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  direct  customer 
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  AAC  is  no  longer  rated  by  an  independent  rating 
agency,  counterparties  have  the  right  to  terminate  the  swap 
positions.

linked 

As of December 31, 2020 and 2019, the net liability fair value of 
derivative 
to 
instruments  with  contingent  features 
Ambac’s own credit risk was $113 and $89, respectively, related 
to which Ambac had posted cash and securities as collateral with 
a  fair  value  of  $130  and  $109,  respectively.  All  such  ratings-
based  contingent  features  have  been 
triggered  requiring 
maximum  collateral  levels  to  be  posted  by  Ambac  while 
preserving  counterparties’  rights  to  terminate  the  contracts. 
Assuming  all  such  contracts  terminated  at  fair  value  on 
December  31,  2020,  settlement  of  collateral  balances  and  net 
derivative liabilities would result in a net receipt of cash and/or 
securities  by  Ambac.  If  counterparties  elect  to  exercise  their 
right to terminate, the actual termination payment amounts will 
be  determined  in  accordance  with  derivative  contract  terms, 
which  may  result  in  amounts  that  differ  from  market  values  as 
reported in Ambac’s financial statements.

Interest Rate Derivatives

Ambac,  through  its  subsidiary  Ambac  Financial  Services 
(“AFS”), uses interest rate swaps, US Treasury futures contracts 
and  other  derivatives,  to  provide  a  partial  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,  2020  and  2019,  the  notional  amounts  of  AFS's

Surplus Notes

Ambac  Assurance's  surplus  notes,  with  a  par  amount  of  $531 
and $531 at December 31, 2020 and 2019, respectively, have a 
scheduled maturity of June 7, 2020.  Surplus notes outstanding 
are  recorded  at  their  fair  value  at  the  date  of  issuance.  The 
discount  on  surplus  notes  was  accreted  into  income  using  the 
effective  interest  method  based  on  projected  cash  flows  at  the 
date of issuance through June 7, 2020, using a weighted average 
imputed interest rate of 10.1%. 

Surplus  note  principal  and  interest  payments  require  the 
approval of OCI. Since the issuance of the surplus notes in 2010, 
OCI  has  declined  to  approve  regular  payments  of  interest  on 
surplus  notes,  although  the  OCI  has  permitted  exceptional 
payments  in  connection  with  (a)  increasing  the  percentage  of 
deferred policy payments of the Segregated Account of Ambac 
Assurance  from  25%  to  45%  in  2014  and  (b)  a  one-time 
payment of approximately six months of interest on the surplus 
notes  outstanding  immediately  after  consummation  of  the 
Rehabilitation Exit Transactions in 2018 in the amount of  $14, 
of  which  $3  was  received  by  AFG  for  surplus  notes  that  it 
owned  and  that  are  considered  extinguished  for  accounting 
purposes. 

In April 2020, OCI declined the request of Ambac Assurance to 
pay  the  principal  amount  of  the  surplus  notes,  plus  all  accrued 
and  unpaid  interest  thereon,  on  the  scheduled  maturity  date  of 
June  7,  2020.  As  a  result,  the  scheduled  payment  date  for 
interest,  and  the  scheduled  maturity  date  for  payment  of 
principal of the surplus notes, shall be extended until OCI grants 
approval to make the payment. Interest will accrue, compounded 
on  each  anniversary  of  the  original  scheduled  payment  date  or 
scheduled  maturity  date,  on  any  unpaid  principal  or  interest 
through the actual date of payment, at 5.1% per annum. 

Refer  to  Note  1.  Background  and  Business  Description  for 
further  discussion  of  the  Rehabilitation  Exit  Transactions,  the 
AMPS  Exchange  and  the  2021  Surplus  Note  Exchanges,  each 
involving the issuance of surplus notes by AAC.

The retirement of certain notes as part of the Rehabilitation Exit 
Transactions in 2018 resulted in gains of $3 for the year ended 

The  junior  surplus  notes  have  a  par  value  of  $365  and  $365  at 
December  31,  2020  and  2019,  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.

• Par value at December 31, 2020 and 2019 includes $15 and 
in 
$15,  respectively,  of 
connection  with  a  settlement  agreement  (the  “OSS 
Settlement Agreement”) entered into among Ambac, AAC, 
the  Segregated  Account  and  One  State  Street,  LLC 
(“OSS”) with respect to the termination of Ambac’s office 
lease  with  OSS.  A  portion  of  the  principal  balance  of  the 
originally issued notes were reduced based on rents paid to 
OSS by AAC after December 31, 2015. Par value of these 
junior  surplus  notes  was  reduced  by  $0  and  $2  during  the 
years ended  December 31, 2020 and 2019, respectively, as 
rent  payments  were  made  by  Ambac  Assurance.  As  of 
December 31, 2020, there was no remaining balance of the 
junior  surplus  notes  that  can  be  reduced  on  rents  paid    by 
AAC. These junior surplus notes were recorded at their fair 
value  at  the  date  of  issuance.  The  discount  on  these  notes 
was accreted into income from the date of issuance through 
June  7,  2020,  using  the  effective  interest  method  at  an 
imputed  interest  rate  of  19.5%.    As  further  described  in 
Note 1. Background and Business Description, on February 
11,  2021,  AAC  completed  the  JSN  Exchange,  pursuant  to 
which  it  acquired  all  remaining    junior  surplus  notes 
originally  issued  in  connection  with  the  OSS  Settlement 
Agreement.

the  Segregated  Account, 

• Par value at December 31, 2020 and 2019 includes $350 of 
a  junior  surplus  note  originally  issued  to  AFG  pursuant  to 
AFG's Chapter 11 Reorganization Plan in accordance with 
the  Mediation  Agreement  dated  September  21,  2011, 
among  AFG,  AAC, 
the 
Rehabilitator,  the  OCI  and  the  Official  Committee  of 
Unsecured  Creditors  of  AFG,  and  that  AFG  sold  to  the 
Corolla 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%.  As 
further  described  in  Note  1.  Background  and  Business 
Description,  on  January  22,  2021,  AAC  completed  the 
Corolla  Note  Exchange,  pursuant  to  which  it  effectively 
acquired the junior surplus notes from the Corolla Trust.

of  3-month  U.S.  Dollar  LIBOR  +  5.00%,  subject  to  a  1.00% 
LIBOR  floor.  During  the  years  ended  December  31,  2020  and 
2019,  $121  and  $178  par  value  of  the  Ambac  Note  was 
redeemed, respectively.  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 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 
(the  “Mandatory 
(i)  apply  an  amount 
Redemption  Amount”)  equal  to  the  lesser  of  (a)  the  amount  of 
representation and warranty subrogation recoveries up to $1,400 
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.

in 

• 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 
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%.    Refer  to  Note  1. 
Background  and  Business  Description  for  further  discussion  of 
the  Rehabilitation  Exit  Transactions  in  connection  with  which 
the  Ambac  Note  was  issued.    Refer  to  the  discussion  under 
"Counterparty  Collateral,  Deposits  with  Regulators  and  Other 
Restrictions" in Note 10. Investments for further information on

Tier 2 Notes

The  Tier  2  Notes,  issued  in  connection  with  the  Rehabilitation 
Exit  Transactions  on  February  12,  2018,  with  a  par  value  of 
$306 and $281 (including paid-in-kind interest of $66 and $41) 

at  December  31,  2020  and  2019,  respectively,  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 upon: (i) 
receipt of representation and warranty subrogation recoveries in 
excess  of  $1,600  ("Tier  2  Net  Proceeds")  and  (ii)  payment  of 
principal  or  interest  on  AAC  surplus  notes.    Promptly,  and  in 
any  event  within  five  business  days  after  the  receipt  (whether 
directly or indirectly) of Tier 2 Net Proceeds, AAC 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 of the consideration 
received  by  AAC.  Similarly,  within  five  business  dates  after  a 
surplus  note  payment  (other  than  in  connection  with  the 
Rehabilitation Exit Transactions), AAC 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 on the initial 
call  date  for  the  Tier  2  Notes  or,  if  the  initial  call  date  has 
occurred,  promptly  following  the  receipt  of  the  Tier  2  Net 
Proceeds or surplus note payment.  

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. 

Ambac UK Debt

The Ambac UK debt, issued in connection with the  Ballantyne 
commutation on June 18, 2019, has a par value of $41 and $41 
at  December 31, 2020 and 2019, and a legal maturity of May 2, 
2036.  Interest  on  the  Ambac  UK  debt  is  at  an  annual  rate  of 
0.00%. The Ambac UK debt was recorded at its fair value at the 
date  of  issuance.  The  discount  on  the  debt  is  currently  being 
accreted  into  income  using  the  effective  interest  method  at  an 
imputed interest rate of 7.4%.

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  VIEs  
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  $3,927  and  $3,990  as  of  December  31,  2020  and 
2019,  respectively.  As  of  December  31,  2020  and  2019,  the 
ranges of final maturity dates of the outstanding long-term debt 
associated with these VIEs were December 2025 to August 2054 
and  December  2025  to  August  2054,  respectively.    As  of 
December 31, 2020 and 2019, the interest rates on these VIEs’ 
long-term  debt  ranged  from  0.00%  to  7.93%  in  both  years.

In  accordance  with  the  Income  Tax  Topic  of  the  ASC,  a 
valuation  allowance  is  recognized  if,  based  on  the  weight  of 
available evidence, it is more-likely-than-not that some, or all, of 
the deferred tax asset will not be realized. As a result of the risks 
and  uncertainties  associated  with  future  operating  results, 
management  believes  it  is  more  likely  than  not  that  the 
Company  will  not  generate  sufficient  U.S.  federal,  state  and/or 
local taxable income to recover the deferred tax operating assets 
therefore  maintains  a  full  valuation  allowance.  The 
and 
remaining  net  deferred  tax  liability  of  $24  is  attributable  to 
Ambac U.K.

NOL Usage

In  December  2020,  AFG  and  certain  subsidiaries  and  affiliates 
amended  their  existing  tax  sharing  agreement  (the  "Third  TSA 
Amendment").    Under  the  Third  TSA  Amendment,  AAC  and 
AFG  agreed  to  reallocate  $210  of  net  operating  loss  carry-
forwards (“NOLs”) from AAC to AFG and to eliminate AAC's 
requirement to make future payments based on its utilization of 
NOLs ("tolling payments") for any taxable year beginning on or 
after  January  1,  2019.  In  connection  with  the  Third  TSA 
Amendment,  AAC  paid  to  AFG  approximately  $28  of  accrued 
tolling  payments  based  on  NOLs  used  by  AAC  in  2017.  The 
Third TSA Amendment did not affect the NOL tolling payments 
AAC  would  be  required  to  make  in  connection  with  the  2013 
Closing  Agreement  between  Ambac  and  the  United  States 
Internal Revenue Service, which could amount to as much as $8.

As  of  December  31,  2020,  the  Company  has  $3,639  of  NOLs, 
which if not utilized will begin expiring in 2029, and will fully 
expire in 2041.

15.   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 predefined age and service requirements. None of the 
plans are currently funded.  Postretirement and postemployment 
benefits expense, including severance benefits paid, were $1, $3 
and $1 for the years ended December 31, 2020, 2019 and 2018, 
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 $10 as of December 31, 2020. The assumed health care cost 
trend rates range from 5.2% in 2021, decreasing ratably to 4.5% 
in 2030.

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 
a  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, 2020 and 
2019, were 2.25% and 3.00%, respectively. 

Savings Incentive Plan

Substantially  all  employees  of  AAC  are  covered  by  a  defined 
contribution  plan  (the  “Savings  Incentive  Plan”).  AAC  makes 
employer  matching  contributions  equal 
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,  $1  and  $1  for  the  years  December  31, 
2020, 2019 and 2018, respectively.

Incentive Compensation - Stock Units and Cash

term 

Incentive compensation is a key component of our compensation 
strategy. Our incentive compensation awards generally have two 
components:  short 
incentive  compensation  awards 
("STIP") and long term incentive plan awards ("LTIP").  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.    In  addition  to  the  stock  based  awards 
discussed below, Ambac's incentive compensation includes cash 
payments which may consist of annual awards under the STIP, 
deferred payments that vest over two years or other performance 
based cash awards.  For all employees, an allocation of incentive 
compensation is made between STIP and LTIP awards. 

Employees,  directors  and  consultants  of  Ambac  are  eligible  to 
participate  in  Ambac’s  2020  Incentive  Compensation  Plan 
(“2020 Plan”), which is the successor plan to the 2013 Incentive 
Compensation  Plan  ("2013  Plan"),  subject  to  the  discretion  of 
the  compensation  committee  of  Ambac’s  Board  of  Directors.  

The  2020  Plan  and  2013  Plan  each  provide  for  incentives  and 
rewards  that  are  valued  or  determined  by  reference  to  Ambac 
common  stock  as  currently  traded  on  the  New  York  Stock 
Exchange.  Beginning with the June 2, 2020, effective date (the 
"Effective  Date")  of  the  2020  Plan,  all  new  awards  are  granted 
under  the  2020  Plan  and  may  not  be  granted  under  the  2013 
Plan.    However,  the  terms  and  conditions  of  the  2013  Plan  
continue  to  govern  outstanding  awards  granted  under  the  2013 
Plan.    There  are  1,475,000  and  4,000,000  shares  of  Ambac's 
common  stock  authorized  for  issuance  that  can  be  awarded 
under the 2020 Plan and 2013 Plan, respectively.  Awards may 
also be made under the 2020 Plan with respect to the shares that, 
as of the Effective Date, remained available for grant under the 
2013  Plan.    In  addition,  shares  subject  to  outstanding  awards 
granted  under  the  2013  Plan  as  of  the  Effective  Date  that 
subsequently terminate by expiration or forfeiture, cancellation, 
or  otherwise  without  the  issuance  of  such  shares  will  become 
available  for  awards  under  the  2020  Plan.    Of  the  total  shares 
authorized for issuance pursuant to the 2020 Plan and 2013 Plan, 
2,096,292  shares  are  available  for  future  grant  as  of  December 
31,  2020.    Shares  available  for  future  grant  are  reduced  by  the 
maximum  number  of  shares  that  could  be  issued  pursuant  to 
  The  number  of  shares 
outstanding  performance  awards. 
available  for  future  grant  considering  the  target  number  of 
shares  instead  of  the  maximum  number  of  shares  related  to 
performance awards is 3,058,603.

No  stock  options  were  exercised  during  the  years  ended 
December 31, 2020, 2019 and 2018, respectively.

Restricted Stock Units (“RSUs”)

to  consultants 

RSUs have been awarded to certain employees for a portion of 
their  STIP  compensation,  LTIP  compensation,  sign-on,  special 
awards  for  exceptional  performance.    RSUs  have  also  been 
awarded 
for  meeting  certain  contractual 
performance  goals.  The  previously  issued  STIP  awards  vested 
upon  grant,  but  settlement  was  deferred  (other  than  for 
employment  tax  withholdings)  into  two  equal  installments 
generally  on  the  first  and  second  anniversary  date  of  the  grant.  
The  LTIP,  sign-on  and  special  awards  generally  vest  in  equal 
installments over a two to three year period.  Awards granted to 
consultants vest on the second year anniversary of date of grant. 
Such  vesting  is  expressly  conditioned  upon  the  respective 
employees  or  non-employees  continued  service  with  Ambac

the  applicable  vesting  date,  although  vesting 

RSUs  have  been  awarded  annually  to  directors  and  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, 2020, 773,657 RSUs remained outstanding, 
of which (i) 345,302 units required future service as a condition 
to  the  delivery  of  the  underlying  shares  of  common  stock  and 
(ii) 428,355 units do not require future service and are deferred 
for future settlement.  As of December 31, 2019, 702,579 RSUs 
remained outstanding, of which (i) 248,942 units required future 
service as a condition to the delivery of the underlying shares of 
common  stock,  and  (ii)  453,637  units  did  not  require  future 
service and were deferred for future settlement.

(1)  When  restricted  stock  unit  awards  issued  by  Ambac  become 
taxable  compensation  to  employees,  shares  may  be  withheld  to 

cover  the  employee’s  withholding  taxes.    For  the  year  ended 
December  31,  2020,  Ambac  purchased  85,654  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  2020,  2019  and  2018  was  $17.36,  $19.75  and 
$16.35, respectively.  As of December 31, 2020, there was $4 of 
total unrecognized compensation costs related to unvested RSUs 
granted.  These  costs  are  expected  to  be  recognized  over  a 
weighted  average  period  of  1.6  years.  The  fair  value  for  RSUs 
vested and delivered during the year ended December 31, 2020, 
2019 and 2018 was $4, $4 and $1, respectively.

Performance Stock Awards ("PSUs")

Performance  awards  granted  vest  in  3  years  and  awards  have 
components relative to performance at AFG and AAC.   Actual 
awards can payout 0% to 220% of the number of units granted.  
Under  currently  outstanding  award  agreements,  performance 
will be evaluated as follows:

• AFG performance will be evaluated relative to cumulative 
earnings  before 
and 
amortization over the vesting period (exclusive of AAC and 
its  subsidiaries'  earnings),  which  is  intended  to  reward 
participants for generating pre-tax income.

(ii) reductions in watch list and adversely classified credits, 
which is intended to reward participants for de-risking the

• In  2019,  a  relative  Total  Shareholder  Return  modifier  was 
added  as  an  additional  metric  with  respect  to  the  LTIP 
award  payouts.    The  modifier  will  cause  the  payout  at  the 
end of the performance period to be increased or decreased 
by  10%  if  AFG's  stock  performance  compared  to  a  peer 
group is at or above the 75th percentile or at or below the 
25th percentile, respectively.

These  performance  metrics  are  subject  to  change  by  the 
Compensation Committee of the Board of Directors as Ambac's 
business evolves.

Other than voluntary termination or involuntary termination for 
cause, and provided that the participant meets certain minimum 
service  requirements,  the  performance  awards  are  subject  to 
either  partial  or  accelerated  vesting.    The  current  performance 
awards  shall  be  settled  within  75  days  after  the  end  of  the 
performance  period,  including  those  with  partial  or  accelerated 
vesting.

16.   LEASES 

Ambac adopted the New Lease Standard, as defined and further 
described  in  Note  2.  Basis  of  Presentation  and  Significant 
Accounting Policies on January 1, 2019. Ambac is the lessee and 
lessor for certain lease agreements further described  below.

Lessee information

Ambac  is  the  lessee  in  operating  leases  for  corporate  offices,  a 
data  center  and  equipment.  Ambac's  purchase  of  Xchange 
resulted  in  additional  office  and  equipment  leases.  Leases  in 
effect  at  December  31,  2020,  have  remaining  lease  terms 
ranging from less than 1 year  to 9 years. Our data center lease 
has  an  automatic  renewal  of  one-year  unless  either  party  elects 
to terminate by providing 120 days notice prior to the renewal. 
This  renewal  feature  is  not  recognized  in  the  lease  liability  or 
right-of-use asset as it is not reasonably certain we will elect to 
renew.  An  office  lease  related  to  Xchange  includes  a  one-time 
early termination provision.  The lease liability and right-of-use 
asset  on  this  lease  consider  its  full  term  as  Ambac  does  not 
reasonably  expect  to  exercise  the  early  termination  option.    No 
other leases contain extension or termination provisions.

fraudulent  misrepresentation, 

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 AAC, a former 
employee of AAC, 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, 
fraudulent 
concealment  and  (vi)  conspiracy  to  commit  fraud.    The  claims 
relate to bonds and debt certificates (insured by AAC) 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, 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 AAC’s 
and  the  other  defendants’  motion  to  dismiss  the  first  amended 
complaint  without  prejudice.  On  December  17,  2018,  Plaintiffs 
filed  a  second  amended  complaint.      On  February  15,  2019, 
Ambac  and  the  other  defendants  filed  a  motion  to  dismiss  the 
second amended complaint.  On September 26, 2019, the court 
issued a decision denying defendants’ motion to dismiss and sua 
sponte reconsidering its previous denial of defendants’ motion to 
transfer venue to the Southern District of New York (“SDNY”).  
On October 4, 2019, the case was transferred to the SDNY.  On 
October 10, 2019, the defendants filed motions in the SDNY to 
vacate  or  reconsider  the  decision  by  the  Northern  District  of 
California on the defendants’ motion to dismiss.  On October 24, 

2019,  plaintiffs  filed  their  brief  in  opposition  to  defendants' 
motions  to  vacate  or  reconsider,  and  on  October  31,  2019, 
defendants  filed  their  reply  briefs  in  further  support  of  their 
motions.  On  November  20,  2019,  the  court  ordered  that  the 
defendants’ answers to the second amended complaint would be 
due seven days after the court issues a decision on their motions.

Management  Board  for  Puerto  Rico  (the  "Oversight  Board"), 
together with the Official Committee of Unsecured Creditors for

unsecured obligations and, in the alternative, seeks to avoid any 
security interests that holders of such bonds may have.  On June 
12,  2019,  a  group  of  general  obligation  bondholders  moved  to 
dismiss  the  complaint.  On  June  13,  2019,  at  the  request  of  the 
Plaintiffs,  the  District  Court  stayed  the  case  until  September  1, 
2019  as  to  all  defendants;  on  July  24,  2019,  the  District  Court 
referred this matter to mediation and ordered it stayed during the 
pendency of such mediation. AAC filed a statement of position 
and  reservation  of  rights  on  February  5,  2020;  certain  other 
defendants  filed  motions  to  dismiss  on  this  same  date.    On 
February 9, 2020, the Oversight Board announced that it intends 
to  file,  and  to  seek  to  confirm,  an  amended  plan  of  adjustment 
(the  “Amended  POA”).  On  March  10,  2020,  the  District  Court 
ordered that this case remain stayed while the Oversight Board 
attempts to confirm the Amended POA.

together  with  the  Committee,  as  Plaintiffs,  filed  an  adversary 
proceeding  against  certain  parties  that  filed  proofs  of  claim  on 
account  of  bonds  issued  by  the  Puerto  Rico  Highways  and 
Transportation  Authority  ("PRHTA"),  including  AAC.    The 
complaint  seeks  declarations  that  the  PRHTA  bonds  are  only 
secured  by  revenues  on  deposit  with  the  PRHTA  Fiscal  Agent 
and  that  PRHTA  bondholders  have  no  security  interest  in  any 
other  property  of  PRHTA  or  the  Commonwealth,  and  in  the 
alternative,  to  the  extent  such  other  security  interests  exist,  the 
complaint seeks to avoid other security interests that holders of 
PRHTA  bonds  may  have.    On  June  14,  2019,  at  the  request  of 
the Plaintiffs, the District Court stayed the case until September 
1, 2019 as to all defendants; on July 24, 2019, the District Court 
referred this matter to mediation and ordered it stayed during the 
pendency  of  such  mediation.    On  December  19,  2019,  the 
District  Court  ordered  that  this  matter  will  remain  stayed 
pending  further  order  of  the  District  Court  pursuant  to  the 
Oversight Board’s initiation of a separate adversary proceeding 
concerning PRHTA bonds (No. 20-ap-00005, discussed below).

Pursuant to an order of the District Court setting out an agreed 
schedule  for  litigation  submitted  by  the  team  of  mediators 
designated  in  the  Commonwealth’s  restructuring  cases  (the 
“Mediation  Team“),  on  January  16,  2020,  the  Oversight  Board 
filed an adversary proceeding against monoline insurers insuring 
bonds  issued  by  the  Puerto  Rico  Infrastructure  Financing 
Authority (“PRIFA”) and the PRIFA bond trustee, all of which 
Defendants  filed  proofs  of  claim  against  the  Commonwealth 
relating  to  PRIFA  bonds.    The  complaint  seeks  to  disallow 
Defendants’ proofs of claim against the Commonwealth in their 
entirety,  including  for  lack  of  secured  status.  On  February  27, 
2020, defendants filed motions to dismiss.  On March 10, 2020, 
the District Court stayed the motions to dismiss and authorized 
the  Oversight  Board  to  move  for  summary  judgment,  which

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

AAC has periodically received various regulatory inquiries and 
requests  for  information  with  respect  to  investigations  and 
inquiries that such regulators are conducting. AAC has complied 
with all such inquiries and requests for information.

The  Company  is  involved  from  time  to  time  in  various  routine 
legal  proceedings,  including  proceedings  related  to  litigation 
with  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.

From  time  to  time,  Ambac  is  subject  to  allegations  concerning 
its  corporate  governance  that  may  lead  to  litigation,  including 
derivative litigation, and while the monetary impacts may not be 
material, the matters may distract management and the Board of 
Directors  from  their  principal  focus  on  Ambac's  business, 
strategy and objectives.

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 
either not applicable or 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 
from  unfavorable  outcomes.  Under  some 
could 
circumstances, adverse results in any such proceedings could be 
material 
financial  position, 
profitability  or  cash  flows.  The  Company  believes  that  it  has 
substantial  defenses  to  the  claims  above  and,  to  the  extent  that 
these  actions  proceed,  the  Company  intends  to  defend  itself 
vigorously;  however,  the  Company  is  not  able  to  predict  the 
outcomes of these actions.

In  the  ordinary  course  of  their  businesses,  certain  of  Ambac’s

during  any  quarter  or  fiscal  year  could  be  material  to  Ambac’s 
results of operations in that quarter or fiscal year.

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).  AAC,  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  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). AAC 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.  AAC  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 AAC 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 
AAC 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

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  April  12,  2019,  the 
Oversight  Board  and  the  Puerto  Rico  Fiscal  Agency  and 
Financial  Advisory  Authority  ("AAFAF")  moved  to  dismiss 
these appeals as equitably moot because the COFINA Plan has 
been  consummated.  On  February  8,  2021,  the  First  Circuit 
dismissed the appeals of the confirmation order. 

Ambac  Assurance  Corporation  v.  Puerto  Rico,  et  al.  (United 
States District Court, District of Puerto Rico, No. 17-1567, filed 
May 2, 2017). On May 2, 2017, AAC filed a complaint seeking 
a  declaration  that  the  Commonwealth’s  Fiscal  and  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.  AAC  anticipates  that  this  case  will 
be voluntarily dismissed 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, AAC filed a complaint alleging 
that  various  moratorium  laws  and  executive  orders  enacted  by 
the  Commonwealth  to  claw  back  funds  from  PRIFA,  PRHTA, 
and  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

Commonwealth and PRHTA (respectively).  On May 17, 2017, 
the court issued an order staying this case until further order of

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,  AAC  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 as a result 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, AAC 
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  AAC-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 to the First 
Circuit  Court  of  Appeals.    On  April  12,  2019,  the  Oversight 
Board and AAFAF moved to dismiss these appeals as equitably 
moot  because  the  COFINA  Plan  has  been  consummated.  On 
February 8, 2021, the First Circuit dismissed the appeals of the 
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  AAC,  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 to the First Circuit Court 
of Appeals. On February 20, 2019, on the joint motion of BNY 
and  COFINA,  the  District  Court  dismissed  this  case  with 
prejudice. On April 12, 2019, the Oversight Board and AAFAF 
moved  to  dismiss  these  appeals  as  equitably  moot  because  the 
COFINA Plan has been consummated. On February 8, 2021, the 
First Circuit dismissed the appeals of the confirmation order.

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 AAC, 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.    AAC  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) 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.  On  February  21,  2019,  on  the  joint  motion  of  the  agents 
for  the  Commonwealth  and  COFINA,  the  Oversight  Board, 
AAFAF,  and  all  participating  interested  parties,  the  District 
Court  dismissed 
  Following 
confirmation  of  the  COFINA  Plan,  several  parties  filed  notices 
of appeal of the District Court’s confirmation order to the First 
Circuit  Court  of  Appeals.  On  April  12,  2019,  the  Oversight 
Board and AAFAF moved to dismiss these appeals as equitably 
moot  because  the  COFINA  Plan  has  been  consummated.    On 
February 8, 2021, the First Circuit dismissed the appeals of the 
confirmation order.

Financial  Oversight  and  Management  Board  for  Puerto  Rico  v. 
Public  Buildings  Authority  (United  States  District  Court, 
District of Puerto Rico, No. 1:18-ap-00149, filed December 21, 
2018).    On  December  21,  2018,  the  Oversight  Board,  together 
with  the  Committee,  as  Plaintiffs,  filed  a  complaint  against  the 

Puerto  Rico  Public  Buildings  Authority  (“PBA”)  seeking 
declaratory  judgment  that  the  leases  between  PBA  and  its 
lessees-many of whom are agencies and instrumentalities of the 
Commonwealth-are “disguised financings,” not true leases, and 
therefore should not be afforded administrative expense priority 
under  the  Bankruptcy  Code.    On  March  12,  2019,  AAC  and 
other  interested  parties  were  permitted  to  intervene  in  order  to 
argue  that  the  PBA  leases  are  valid  leases,  and  are  entitled  to 
administrative  expense  treatment  under  the  Bankruptcy  Code.  
On  June  16,  2019,  the  Oversight  Board  announced  that  it  had 
entered  into  a  plan  support  agreement  ("PSA")  with  certain 
general  obligation  and  PBA  bondholders  that  includes  a 
issues 
proposed 
surrounding both general obligation and PBA bonds, including a 
proposed  settlement  of  this  adversary  proceeding.    On  July  24, 
2019,  the  District  Court  referred  this  matter  to  mediation  and 
ordered  it  stayed  during  the  pendency  of  such  mediation.    On 
September  27,  2019,  the  Oversight  Board  filed  a  joint  plan  of 
adjustment  and  disclosure  statement  for  the  Commonwealth, 
PBA,  and  the  Employees’  Retirement  System  for  Puerto  Rico. 
On February 9, 2020, the Oversight Board executed a new plan 
support  agreement  with  additional  creditors  (the  “Amended 
PSA”) and announced that it intends to file, and seek to confirm, 
the  Amended  POA.    On  March  10,  2020,  the  District  Court 
ordered  that  this  case  be  stayed  while  the  Oversight  Board 
attempts to confirm the Amended POA.

In  re  Financial  Oversight  and  Management  Board  for  Puerto 
Rico (United States District Court, District of Puerto Rico, No. 
1:17-bk-03283),  Omnibus  Objection  of  (I)  Financial  Oversight 
and  Management  Board,  Acting  Through  its  Special  Claims 
Committee, and (II) Official Committee of Unsecured Creditors, 
Pursuant to Bankruptcy Code Section 502 and Bankruptcy Rule 
3007,  to  Claims  Filed  or  Asserted  by  Holders  of  Certain 
Commonwealth General Obligation Bonds (Dkt. No. 4784, filed 
January  14,  2019)  (“GO  Bond  Claim  Objection  Procedures”).  
On  January  14,  2019,  the  Oversight  Board  and  the  Committee 
filed  an  omnibus  claim  objection  in  the  Commonwealth’s  Title 
III  case  challenging  claims  arising  from  certain  general 
obligation  bonds  issued  by  the  Commonwealth  in  2012  and 
2014 totaling  approximately  $6 billion, none  of which are held 
or  insured  by  AAC.    The  court  subsequently  ordered  certain 
consolidated  procedures  permitting  parties 
interest  an 
opportunity to participate in litigation of the objection.  On April 
11,  2019,  AAC  filed  a  notice  of  participation  in  support  of  the 
objection, advancing the argument, among other things, that the 
PBA  leases  are  true  leases,  but  the  associated  debt  nonetheless 
should  be  included  in  the  Commonwealth’s  debt  ceiling 
calculation such that the 2012 and 2014 general obligation bond 
issuances are null and void and claims arising therefrom should 
be  disallowed.    On  June  16,  2019,  the  Oversight  Board 
announced  that  it  had  entered  into  a  PSA  with  certain  general 
obligation  and  PBA  bondholders  that  includes  a  proposed 
resolution  of  claim  objections  to  and  issues  surrounding  both 
general  obligation  and  PBA  bonds,  including  a  proposed 
settlement of this omnibus claim objection.  On June 25, 2019, 
the  Oversight  Board  moved  to  stay  proceedings  related  to  this 
omnibus  claim  objection  while  it  pursues  confirmation  of  the 
plan  contemplated  in  the  PSA.    On  July  24,  2019,  the  District 
Court  referred  this  matter  to  mediation  and  ordered  it  stayed 
during  the  pendency  of  such  mediation.    On  February  5,  2020,

certain parties filed motions to dismiss the claim objection.  On 
February  9,  2020,  the  Oversight  Board  executed  the  Amended 
PSA and announced that it intends to file, and seek to confirm, 
the Amended POA. Additional motions to dismiss were filed on 
February  19,  2020.  On  March  10,  2020,  the  District  Court 
ordered that this matter remain stayed while the Oversight Board 
attempts  to  confirm  the  Amended  POA.  On  July  19,  2020,  the 
Committee filed a motion to lift the stay on this claim objection 
in light of the changes to the fiscal plan and likely changes to the 
Commonwealth  plan  of  adjustment  in  light  of  COVID-19.    On 
September  1,  2020,  AAC  filed  a  partial  joinder  to  the 
Committee’s motion.  On September 17, 2020, the District Court 
denied  the  Committee’s  motion  without  prejudice,  indicating 
that  the  stay  likely  would  remain  in  place  until  at  least  March 
2021.    On  October  1,  2020,  the  Committee  moved  the  District 
Court to reconsider its denial of the Committee’s motion to lift 
the  stay  in  light  of  materials  released  by  the  parties  to  the 
Amended PSA that the Committee argued demonstrate a lack of 
agreement  between  those  parties.    On  October  5,  2020,  the 
District  Court 
for 
reconsideration.  On October 16, 2020, the Committee appealed 
to  the  First  Circuit  the  District  Court’s  order  denying  the 
Committee’s  motion  to  lift  the  stay  on  its  claim  objection.  On 
February 22, 2021, the First Circuit dismissed the appeal.

Strike Certain Provisions of the Plan Support Agreement By and 
Among  the  Financial  Oversight  and  Management  Board  for 
Puerto  Rico,  Certain  GO  Holders,  and  Certain  PBA  Holders 
(Dkt.  No.  13573,  filed  July  7,  2020)  (“Amended  Motion  to 
Strike  PSA”).    On  June  16,  2019,  the  Oversight  Board 
announced  that  it  had  entered  into  a  PSA  with  certain  general 
obligation  and  PBA  bondholders  that  includes  a  proposed 
resolution  of  claim  objections  to  and  issues  surrounding  both 
general  obligation  and  PBA  bonds.    On  July  16,  2019,  AAC 
filed  a  motion  to  strike  certain  provisions  of  the  PSA  that  it 
believes violate PROMESA, including the potential payment of 
a  breakup  fee  to  creditors  who  have  supported  the  PSA  (Dkt. 
No.  8020)  (Original  Motion  to  Strike  PSA).    On  February  9, 
2020,  the  Oversight  Board  executed  the  Amended  PSA  and  on 
March  10,  2020,  the  District  Court  denied  the  Original  Motion 
to  Strike  PSA  without  prejudice  given  the  execution  of  the 
Amended  PSA.    On  July  7,  2020,  AAC  filed  the  Amended 
Motion  to  Strike  PSA  seeking  similar  relief  with  respect  to  the 
Amended PSA.  Briefing on the Amended Motion to Strike PSA 
concluded on October 20, 2020, and the District Court has taken 
the matter on submission. On February 23, 2021, the Oversight 
Board announced that it entered into a further revised PSA (the 
“Second  Amended  PSA”),  and  that  all  parties  to  the  Amended 
PSA had jointly terminated the Amended PSA.

Memorandum  of  Law  in  Support  of  Its  Motion  Concerning 
Application  of  the  Automatic  Stay  to  the  Revenues  Securing 
PRIFA  Rum  Tax  Bonds  (Dkt.  No.  7176,  filed  May  30,  2019) 
(“PRIFA Stay Motion”).  On May 30, 2019, AAC filed a motion 
seeking an order that the automatic stay does not apply to certain 

lawsuits  AAC  seeks  to  bring  or  to  continue  relating  to  bonds 
issued  by  PRIFA,  or,  in  the  alternative,  for  relief  from  the 
automatic stay to pursue such lawsuits or for adequate protection 
of  AAC's  collateral.  On  July  24,  2019,  the  District  Court 
referred this matter to mediation and ordered it stayed during the 
pendency of such mediation.  On January 31, 2020, the District 
Court  granted  a  motion  filed  by  AAC,  together  with  Assured 
Guaranty  Corporation,  Assured  Guaranty  Municipal 
Corporation,  and  Financial  Guaranty  Insurance  Company  to 
amend  the  PRIFA  Stay  Motion  in  order  to  allow  the  PRIFA 
bond  trustee  to  join  the  amended  motion  and  to  allow  movants 
to  address  recent,  controlling  precedent  from  the  First  Circuit, 
and  AAC  filed  the  amended  motion  the  same  day.    On  July  2, 
2020,  the  District  Court  denied  the  motion  to  lift  the  stay  on 
certain grounds. Briefing regarding additional grounds on which 
AAC and other movants seek stay relief concluded on August 5, 
2020;  on  September  9,  2020,  the  District  Court  denied  the 
motion to lift the stay on the additional grounds.  On September 
23, 2020, AAC and the other movants appealed this decision to 
the First Circuit. Oral argument was held before the First Circuit 
on February 4, 2021.

to  the  PRHTA  bonds  or  the  enforcement  of  movants’  liens  on 
revenues  pledged  to  such  bonds,  or,  in  the  alternative,  for 
adequate  protection  of  movants’  interests  in  the  revenues 
pledged  to  PRHTA  bonds.  On  July  2,  2020,  the  District  Court 
denied  the  motion  to  lift  the  stay  on  certain  grounds.    Briefing

bonds by bringing an enforcement action against PRCCDA; or, 
in  the  alternative,  (ii)  lifting  the  automatic  stay  to  enable 
movants to pursue an enforcement action against PRCCDA; or, 
in  the  further  alternative,  (iii)  ordering  adequate  protection  of 
movants’ interests in the PRCCDA pledged to PRCCDA bonds. 
On July 2, 2020, the District Court denied the motion to lift the 
stay on certain grounds, but found that the movants had stated a 
colorable  claim  that  a  certain  account  was  the  “Transfer 
Account”  on  which  movants  hold  a  lien.  Briefing  regarding 
additional grounds on which AAC and other movants seek stay 
relief concluded on August 5, 2020; on September 9, 2020, the 
District Court denied the motion to lift the stay on the additional 
grounds, and found that a final determination on issues related to 
the  identity  of  the  Transfer  Account  would  be  made  in  the 
decision  on  the  motions  for  summary  judgment  issued  in  the 
CCDA-related adversary proceeding, No. 20-ap-00004.

Juan  Superior  Court,  Case  No.  SJ-2020-CV-01505,  filed 
February  19,  2020).  On  February  19,  2020,  AAC  filed  a 
complaint in the Commonwealth of Puerto Rico, Court of First 
Instance,  San  Juan  Superior  Court,  against  certain  underwriters 
of  Ambac-insured  bonds  issued  by  PRIFA  and  PRCCDA,  with 
causes  of  action  under  the  Puerto  Rico  civil  law  doctrines  of 
actos proprios and Unilateral Declaration of Will. AAC alleges 
defendants  engaged  in  inequitable  conduct  in  underwriting 
issued  by  PRIFA  and  PRCCDA, 
Ambac-insured  bonds 
including failing to investigate and adequately disclose material 
information  in  the  official  statements  for  the  bonds  that 
defendants provided to AAC regarding systemic deficiencies in 
the  Commonwealth’s  financial  reporting.  AAC  seeks  damages 
in  compensation  for  claims  paid  by  AAC  on  its  financial 
guaranty  insurance  policies  insuring  such  bonds,  pre-judgment 
and  post-judgment  interest,  and  attorneys’  fees.  On  March  20, 
2020,  Defendants  removed  this  case  to  the  Title  III  Court.  On 
April  20,  2020,  AAC  moved  to  remand  the  case  back  to  the 
Court  of  First  Instance.  On  July  29,  2020,  the  District  Court 
granted  AAC’s  motion 
the 
Commonwealth  court.  AAC  filed  an  amended  complaint  in  the 
Commonwealth  court  on  October  28,  2020.    In  the  Amended 
Complaint,  AAC  added  claims  on  bonds  issued  by  the 
Commonwealth,  PBA  and  PRHTA  and  added  defendants  that 
had  underwritten  these  bonds.    Defendants  filed  motions  to 
dismiss on December 8 and 14, 2020; AAC filed its opposition 
to the motions to dismiss on January 15, 2021. Defendants filed 
replies to their motions to dismiss on February 5 and 16, 2021.  
AAC will file its sur-reply to the motion to dismiss on March 5, 
2021.

Puerto  Rico,  LLC  (United  States  District  Court,  District  of 

for 

Puerto Rico,  No. 3:20-cv-01094,  filed February 19, 2020).  On 
February  19,  2020,  AAC  filed  a  complaint  in  the  U.S.  District 
Court  for  the  District  of  Puerto  Rico,  against  Autopistas 
Metropolitanas  de  Puerto  Rico,  LLC  (“Metropistas”),  which 
holds a concession from PRHTA for two Puerto Rico highways, 
PR-5 and PR-22, in connection with a 10-year extension of the 
concession that was entered into in April 2016.  The complaint 
includes  claims 
fraudulent  conveyance  and  unjust 
enrichment,  alleging  that  the  consideration  paid  by  Metropistas 
for the extension was less than reasonably equivalent value and 
most  of  the  benefit  of  such  payment  was  received  by  the 
Commonwealth  instead  of  PRHTA. 
  AAC  also  seeks  a 
declaratory  judgment  that  it  has  a  valid  and  continuing  lien  on 
certain toll revenues that are being collected by Metropistas. On 
March 31, 2020, the Oversight Board filed a motion before the 
Title III Court seeking an order directing Ambac to withdraw its 
complaint.    On  April  20,  2020,  the  District  Court  ordered  this 
case  stayed  pending  briefing  before  the  Title  III  Court  on  the 
Oversight Board’s motion to withdraw.  On June 16, 2020, the 
Title  III  Court  ordered  AAC  to  withdraw  its  complaint.    AAC 
withdrew its complaint on June 23, 2020, and noticed an appeal 
from  the  Title  III  Court’s  order  to  withdraw  on  June  30,  2020. 
AAC’s opening appeal brief was filed before the First Circuit on 
October 19, 2020; briefing was completed on February 12, 2021. 
Oral argument is scheduled to be heard on March 8, 2021.

Management  Board  for  Puerto  Rico  (United  States  District 
Court, District of Puerto Rico, No. 3:20-ap-00068, filed May 26, 
2020).    On  May  26,  2020,  AAC  filed  an  adversary  complaint 
before the Title III Court seeking (i) a declaration that titles I, II, 
and III of PROMESA are unconstitutional because they violate 
the Bankruptcy Clause of the U.S. Constitution (which requires 
all  bankruptcy  laws  to  be  uniform)  and  (ii)  dismissal  of  the

2020,  movants  noticed  an  appeal  of  the  denial  of  the  HTA 
Trustee  Motion  to  the  First  Circuit.    On  September  30,  2020, 
movants filed a motion with the First Circuit to hold this appeal 
in abeyance pending the First Circuit’s resolution of the appeal 
from  the  District  Court’s  denial  of  the  HTA  Lift-Stay  Motion.  
On October 13, 2020, the Oversight Board opposed the motion 
to  hold  the  appeal  in  abeyance  and  cross-moved  to  dismiss  the 
appeal  as  moot,  arguing  that  the  statute  of  limitations  on  the 
avoidance actions movants wish to pursue has expired.  Briefing 
on both motions concluded on October 27, 2020.  On December 
22, 2020, the First Circuit denied the motion to hold the appeal 
in  abeyance,  and  referred  the  motion  to  dismiss  to  the  panel 
determining  the  merits  of  the  appeal.  Movants’  opening  brief 
before the First Circuit was filed on February 17, 2021; briefing 
is expected to conclude on May 10, 2021.

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 
servicing  practices.   
improprieties 
Simultaneous with the filing of its complaint, CFPB also filed a 
motion to approve a proposed consent judgment that would have 
granted  monetary  damages  and  injunctive  relief  against  the 
Trusts. AAC guaranteed certain securities issued by three of the 
Trusts and indirectly insures six other Trusts.  On September 20, 
2017,  AAC  filed  a  motion  to  intervene  in  the  action,  which 
motion was granted on October 19, 2018.  Following discovery 
and  briefing,  on  May  31,  2020,  the  District  Court  denied  the 
CFPB’s motion to approve the proposed consent judgment.  On 
March  19,  2020,  Intervenor  Transworld  Systems  Inc.  filed  a 
motion  to  dismiss  the  action  for  lack  of  subject  matter 
jurisdiction.    On  July  10,  2020,  AAC  and  several  other 
intervenors  filed  a  motion  to  dismiss  the  action  for  lack  of 
subject  matter  jurisdiction  and  for  failure  to  state  a  claim.  
Briefing on both motions to dismiss is complete.  Additionally, 
on July 2, 2020, the CFPB submitted an application for entry of 
default against the Trusts.  AAC and the Owner Trustee opposed 
the CFPB’s application, which remains pending.

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.    AAC  guaranteed  certain  securities  issued  by  three  of 
the  Trusts  and  indirectly  insures  certain  securities  in  six  other 
Trusts.    AAC  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 AAC’s motion to intervene on April 10, 2018 and AAC 
filed its complaint in intervention on April 16, 2018. On January 
21, 2020, Vice Chancellor Slights entered an order consolidating 
the  action  with  later-filed  litigation  pending  in  Delaware 
Chancery  Court  relating  to  the  Trusts,  including  a  declaratory 
judgment action in which AAC was named as a defendant, NC 
Residuals  Owners  Trust,  et  al.  v.  Wilmington  Trust  Co.,  et  al. 
(Del. Ct. Ch., C.A. No. 2019-0880, filed Nov. 1, 2019).

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,  AAC

on July 13, 2012).  The court dismissed AAC’s claims for 
indemnification  and  limited  AAC’s  claim  for  breach  of

dismissal of AAC’s other contractual claims and fraudulent 
inducement claim. Discovery is ongoing.

28, 2013, asserted claims against Countrywide and Bank of 
America  (as  successor  to  Countrywide’s  liabilities)  for, 
among  other  things,  breach  of  contract  and  fraudulent 
inducement. In August and October 2018, Defendants filed 
various pre-trial motions. On December 30, 2018, the court 
denied  all  of  these  pre-trial  motions  in  their  entirety  and 
Defendants  appealed.  On  September  17,  2019,  the  First 
Department  affirmed  in  part  and  reversed  in  part  the  trial 
court’s rulings. On October 17, 2019, Countrywide filed a 
motion for leave to appeal certain issues to the New York 
Court  of  Appeals  and  for  reargument  or  leave  to  appeal 
certain  other  issues.  On  January  16,  2020,  the  First 
Department  recalled  and  vacated  its  September  17,  2019 
decision  and  order  and  substituted  a  new  decision  and 
order.    On  the  same  date,  the  First  Department  denied 
Countrywide’s  motion  seeking  leave  to  appeal,  without 
prejudice to seeking such leave from the reissued decision 
and order.  On January 30, 2020, Countrywide filed a new 
motion for leave to appeal the First Department’s denial of 
its  motions,  which  AAC  opposed.  On  June  11,  2020,  the 
First Department denied Countrywide’s motion for leave to 
appeal.  On January 14, 2020, the trial court granted AAC’s 
motion  to  supplement  and  amend  certain  of  its  expert 
reports.    After  supplemental  expert  discovery,  on  August 
12, 2020, Countrywide filed a motion to dismiss, or in the 
alternative for summary judgment on, Ambac’s fraud claim 
and on December 4, 2020, the Court granted Countrywide’s 
motion,  resulting  in  dismissal  of  AAC's  fraud  claim.    On 
December  17,  2020,  Ambac  filed  a  notice  of  appeal  from 
this  decision.  On  February  22,  2021,  Ambac  filed  its 
opening brief for this appeal. This appeal remains pending.  
Trial  of  this  matter  had  been  scheduled  to  commence  on 
February  22,  2021,  but  on  December  23,  2020  the  Court 
adjourned the trial due to the COVID-19 pandemic.  A new 
trial date has not been set.

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). 
AAC  has  asserted  claims  for  material  breach  of  contract 
and  has  requested  the  repurchase  of  loans  that  breach 
representations  and  warranties  under  the  contracts.  AAC 
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 
for  breaches  of 
representations and warranties, but granted the defendants’ 
motion  to  dismiss  AAC’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 AAC’s amended complaint and 
its  motion  to  dismiss  the  fraudulent-inducement  claim.  
Nomura  appealed  the  June  2015  decision  to  the  extent  it 

to  dismiss  AAC’s  claim 

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.

• Ambac Assurance Corporation and the Segregated Account

Loans,  Inc.  (Supreme  Court  of  the  State  of  New  York, 
County of New York, Case No. 652321/2015, filed on June 
30,  2015).    On  June  30,  2015,  AAC  and  the  Segregated 
Account  filed  a  Summons  with  Notice  in  New  York 
Supreme  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  AAC  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  AAC’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 
AAC’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.  On 
December 8, 2020, the court granted Countrywide’s motion 
to  dismiss  the  complaint.    AAC  filed  a  notice  of  appeal 
from  this  decision  on  January  7,  2021.  The  court  entered 
judgment in Countrywide’s favor on January 29, 2021 and 
AAC  filed  a  notice  of  appeal  from  the  judgment  on 
February 2, 2021.

relating to eight residential mortgage-backed securitizations 
that are not the subject of AAC’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  has  been  completed.    The

instruction proceeding in Minnesota state court concerning 
the proposed settlement, and on June 12, 2017, U.S. Bank 
filed an amended petition.  AAC filed a motion to dismiss 
the Minnesota Action, which was denied on November 13, 
2017, and the denial was affirmed on appeal. On September 
6, 2018, U.S. Bank filed its Second Amended Petition, and 
AAC  and  certain  other  certificateholders  objected  to,  or 
otherwise  responded  to,  the  petition.  Trial,  which  was 
previously  scheduled  to  begin  February  1,  2021,  has  been 
rescheduled  to  October  11  through  15,  2021.    On  June  8, 
2018, AAC filed the SDNY Action asserting claims arising 
out  of  U.S.  Bank’s  acceptance  of  the  proposed  settlement 
and treatment of trust recoveries.  AAC asserted claims for 
declaratory  judgment,  breach  of  contract,  and  breach  of 
fiduciary  duty.    On  July  16,  2019,  the  court  dismissed 
AAC's  breach-of-contract  and  breach-of-fiduciary-duty 
claims  based  on  U.S.  Bank's  acceptance  of  the  settlement; 
and  dismissed  AAC's  declaratory 
judgment  claims 
regarding  the  occurrence  of  an  Event  of  Default  and  U.S. 
Bank's  future  distribution  of  trust  recoveries  through  the 
waterfall.    The  court  denied  the  motion  to  dismiss  AAC's 
breach-of-contract  claims  based  on  U.S.  Bank's  past 
distribution  of  trust  recoveries  through  the  waterfall.  On 
January 17, 2020, U.S. Bank moved for summary judgment 
regarding the remaining claim relating to distributions.  On 
February  7,  2020,  AAC  cross-moved  for  summary 
judgment.  On  December  7,  2020,  the  court  issued  a 
decision  granting  in  part  and  denying  in  part  the  parties’ 
cross-motions  for  summary  judgment.    The  court  granted 
U.S. Bank’s motion for summary judgment with respect to 
Ambac’s repayment right in the trust waterfall, and granted 
Ambac’s motion for summary judgment with respect to the 
use  of  a  write-up  first  method  and  the  offsetting  of 
recoveries against realized losses.  On December 22, 2020, 
the  court  entered  final  judgment  consistent  with  its  prior 
decisions,  and  awarded  Ambac  nominal  damages.    On 

January  12,  2021,  Ambac  filed  a  notice  of  appeal  of  that 
judgment.

• 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).  AAC 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 AAC 
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 
that  mortgage  documents  were 
properly  delivered  to  the  Trusts;  dismissed  the  Streit  Act 
claims;  and  otherwise  denied  the  motion  to  dismiss. 
Discovery is ongoing.

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

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  November  2,  2018, 
AAC and other interested persons filed notices of intention 
to appear and answers to DBNT’s petition.  AAC  sought a 
period  of  discovery  before  resolution  on  the  merits. 
Discovery  is  now  complete.  Under  the  operative  case 
schedule,  merits  briefing  was  completed  on  January  12, 
2021.  The  court  has  not  yet  scheduled  a  hearing  or  oral 
argument.

Item 9.  Changes in and Disagreements with 

Accountants on Accounting and Financial 
Disclosure — None.

Item 9A.   Controls and Procedures

Evaluation of Disclosure Controls and Procedures. Ambac’s 
disclosure  controls  and  procedures  are  designed  to  ensure  that 
information  required  to  be  disclosed  under  the  Securities 
Exchange  Act  of  1934,  as  amended,  is  recorded,  processed, 
summarized  and  reported  within  the  time  periods  specified  in 
the  SEC’s  rules  and  forms,  including  without  limitation  that 
information required to be disclosed by Ambac in its SEC filings 
is accumulated and communicated to management, including the 
Chief  Executive  Officer  (CEO)  and  Chief  Financial  Officer 
(CFO)  as  appropriate  to  allow  for  timely  decisions  regarding 
required disclosure. 

Ambac’s  Disclosure  Committee  assists  the  CEO  and  CFO  in 
their  responsibilities  to  design,  establish,  maintain  and  evaluate 
the  effectiveness  of  disclosure  controls  and  procedures.  The 
Disclosure  Committee  is  responsible  for,  among  other  things, 
the oversight, maintenance and implementation of the disclosure 
controls and procedures, subject to the supervision and oversight 
of  the  CEO  and  CFO.  Ambac’s  management,  with  the 
participation  of 
the 
effectiveness of Ambac’s disclosure controls and procedures (as 
defined  in  rules  13a-15(e)  and  15d-15(e)  under  the  Securities 
Exchange Act of 1934) as of December 31, 2020 and, the CEO 
and  CFO  have  concluded  that  at  that  date  Ambac’s  disclosure 
controls  and  procedures  were  effective  at  the  reasonable 
assurance level.

its  CEO  and  CFO,  has  evaluated

Reporting. 
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  controls  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.

the 
Ambac  management  conducted  an  assessment  of 
effectiveness  of  Ambac’s 
internal  control  over  financial 
reporting based on the criteria established in the Internal Control 
—  Integrated  Framework  (2013)  issued  by  the  Committee  of 
Sponsoring Organizations of the Treadway Commission.

recognizes 

Ambac  management 
that  any  controls  and 
procedures,  no  matter  how  well  operated,  can  provide  only 
reasonable assurance of achieving their objectives.  Based on its 
evaluations,  Ambac's  management  have  concluded  that,  as  of 
December 31, 2020, 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, 
2020  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  that  occurred  during  the  fourth  quarter  of 
2020  that  materially  affected,  or  are  reasonably  likely  to 
materially  affect,  the  Company's  internal  control  over  financial 
reporting.    We  have  not  experienced  any  significant  change  to 
our internal controls over financial reporting despite the fact that 
our  employees  are  working  remotely  due  to  the  COVID-19 
pandemic.    We  are  continually  monitoring  and  assess  the 
COVID-19  situation  on  our  internal  controls  to  minimize  the 
impact on their design and operating effectiveness.

(1)  Our 2020 Incentive Compensation Plan ("2020 Plan") was approved by the stockholders of AFG on June 2, 2020 as a successor to our 2013 Incentive 
Compensation Plan ("2013 Plan") which was approved on December 18, 2013.   Effective June 2, 2020, awards may no longer be granted under the 
2013 Plan; authorized and unissued shares under the 2013 Plan are available for issuance under the 2020 Plan.  

(2)  Represents, as of December 31, 2020, the number of outstanding restricted stock unit awards and the maximum number of performance stock units that 
may  be  issued  if  certain  performance  goals  are  achieved.  Refer  to  Note  15.  Employment  Benefit  Plans  to  the  Consolidated  Financial  Statements 
included in Part II, Item 8 in this Form 10-K for a description of the grants made under our 2013 and 2020 Incentive Compensation Plans.  This amount 
includes 773,657 restricted stock units and 1,799,959 performance stock units which are based on the maximum number of shares potentially payable 
under the awards.  Maximum number of shares potentially payable under performance awards range from 200% to 220% of target. 

(3)  Each restricted stock unit, stock option and performance stock unit awarded under our 2013 and 2020 Incentive Compensation Plans was granted at no 
cost to the persons receiving them. Restricted stock units represent the contingent right to receive the equivalent number of shares of AFG common 
stock and may vest after the passage of time.  Stock options represent the right to acquire an equivalent number of shares of AFG common stock at a 
specified  exercise  price.    Performance  stock  units  granted  pursuant  to  the  Company's  Long  Term  Incentive  Plan  represent  the  contingent  right  to 
receive a number of shares of AFG common stock ranging from 0% to 220% of the number of units granted depending upon the achievement of certain 
company-wide performance goals at the end of a specified performance period.

(4)   Represents the number of securities remaining available for future issuance under compensation plans assuming the maximum number of shares are 
issued on settlement of performance stock units. The number of securities remaining available for future issuance under compensation plans assuming 
the target number of  shares are issued on settlement of performance stock units would be 3,058,603. 

(5)  There are no outstanding options as of December 31, 2020.  Performance shares and restricted stock units are not included in determining weighted-

average price as they have no exercise price.

AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES
SCHEDULE II— CONDENSED FINANCIAL INFORMATION
OF REGISTRANT (PARENT COMPANY ONLY)
Notes to Condensed Financial Information
(Dollar Amounts in Millions)

The condensed financial information of Ambac Financial Group, 
Inc. (“AFG” or the “Registrant”) as of December 31, 2020 and 
2019, and for the three years in the period ended December 31, 
2020, should be read in conjunction with the consolidated 
financial statements of AFG Financial Group, Inc. and 
Subsidiaries and the notes thereto included in this 2020 Annual 
Report on Form 10-K for the year ended December 31, 2020.
AFG,  headquartered  in  New  York  City,  is  a  financial  services 
holding company incorporated in the state of Delaware on April 
29, 1991. 

Business Combination

On  December  31,  2020,  Ambac  completed  the  acquisition  of  
80%  of  the  membership  interests  of  Xchange  for  a  purchase 
price  of  $81  in  cash.    Xchange,  whose  management  principals 
retained  the  remaining  20%  of  the  company,  will  continue 
operating  under  its  existing  brand  as  it  seeks  to  expand  its 
underwriting partnership with its key carriers in connection with 
its planned growth strategy.  

See Note 3. Business Combination to the Consolidated Financial 
Statements  included  in  Part  II,  Item  8  in  this  Form  10-K  for 
further information.

Income Taxes

AFG files a consolidated Federal income tax return with its U.S. 
subsidiaries.  AFG  and  its  subsidiaries  also  file  separate  or 
combined income tax returns in various states, local and foreign 
jurisdictions.  As  of  December  31,  2020,  Ambac  had 
consolidated  U.S.  federal  loss  carryforwards  ("NOLs")  totaling 
approximately $3,639, which, if not utilized, will begin expiring 
in 2029, and will fully expire in 2041.

Pursuant  to  an  intercompany  tax  sharing  agreement,  taxable 
income  generated  by  AAC  after  September  30,  2011,  is  offset  
by $3,440 of NOLs allocated to AAC.  In December 2020, AFG 
and  certain  affiliates  amended  their  existing  tax  sharing 
agreement  (the  "Third  TSA  Amendment").    Under  the  Third 
TSA  Amendment,  AAC  and  AFG  agreed  to  reallocate  $210  of 
net operating loss carry-forwards (“NOLs”) from AAC to AFG 
and  to  eliminate  AAC's  requirement  to  make  future  payments 
based  on  its  utilization  of  NOLs  ("tolling  payments")  for  any 
taxable  year  beginning  on  or  after  January  1,  2019.  In 
connection with the Third TSA Amendment, AAC paid to AFG 
approximately $28 of accrued tolling payments based on NOLs 
used by AAC in 2017. For the year ended December 31, 2020, 
the AAC sub-group generated an NOL of $270, that will expire 
in 2041. 

The  NOLs  allocated  to  AFG  as  of  December  31,  2020,  were 
$1,457, and begin expiring in 2029 and fully expire in 2033.

Appendix A

Non-GAAP Financial Measures

Ambac reports two non-GAAP financial measures: Adjusted Earnings and Adjusted Book Value. The most directly comparable GAAP measures are 
net  income  attributable  to  common  stockholders  for  Adjusted  Earnings  and  Total  Ambac  Financial  Group,  Inc.  stockholders’  equity  for  Adjusted 
Book  Value.    A  non-GAAP  financial  measure  is  a  numerical  measure  of  financial  performance  or  financial  position  that  excludes  (or  includes) 
amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP.  We are 
presenting these non-GAAP financial measures because they provide greater transparency and enhanced visibility into the underlying drivers of our 
business.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  2020  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,  we utilized a 0% effective tax rate for non-GAAP adjustments; 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.
