COMERICA'S CORE VALUES

ONE COMERICA

THE CUSTOMER
COMES FIRST

THE BIGGER
POSSIBLE

A FORCE FOR GOOD

TRUST. ACT. OWN.

1

We believe that growth is 
achieved when our colleagues 
act with common purpose in 
support of shared goals. 

We put our customers at the center
of every conversation and make
their satisfaction our highest priority.

We encourage a culture of bold and 
relentless curiosity, where any idea 
has a chance to be heard. 

We value empathy and integrity as 
we work to create a more diverse, 
inclusive and sustainable workplace, 
and world. 

Everyone is empowered to do what’s 
right, speak up, and be heard, while 
being accountable for their actions 
and commitments. 

1 Loans and commitments are considered green if the following criteria are met: More than 50% of the company's revenues attributed to environmentally beneficial businesses and/or more than 50% 

of loan proceeds are dedicated to green purposes or projects. There are 14 green loan categories disclosed in the TCFD and Corporate Responsibility report found at www.comerica.com.

TO OUR SHAREHOLDERS

To my fellow shareholders,

For nearly 175 years, Comerica has proudly raised expectations of what a bank can 
be for our customers, businesses, entrepreneurs and communities we serve. Through 
disruptive economic cycles, political discord, world wars, and a global pandemic,  we have 
maintained our stability and strength by focusing on the basics: our relationship-focused 
business model and industry-leading expertise in the select products and services we 
offer. We are deeply dedicated to supporting our customers’ financial goals and honored 
to be their bank of choice. 

To guide our success in 2023, we remained committed to our colleagues, customers, 
communities and performance. Investing and advancing in each of these areas means we 
are delivering for all our stakeholders.

Response to Industry Disruption
Following a strong 2022, the collapse of three regional banks in early March sent 
shockwaves throughout the banking industry, leaving customers concerned about the 
safety of their deposits. Following the volatility – and the news and social media buzz 

Curtis C. Farmer 
Chairman, President and Chief Executive Officer

surrounding it – the banking industry found itself in a challenging environment. But, this also presented an opportunity for Comerica to 
recalibrate while leaning heavily on our strength as a relationship bank.  

During this time, our colleagues rose to the challenge, working diligently with customers, investors and regulators. Leaders and 
frontline colleagues met with customers to listen to their concerns and ease their minds. Behind the scenes, we kept priority projects 
on track and reinforced key messaging. 

While the disruption proved challenging, we once again tested and validated the soundness of our business model. As a leading 
bank for business with strong retail and wealth management capabilities, we play a unique role in supporting our customers as a 
trusted long-term banking partner. Ultimately, our diversified position across businesses, geographies and products, coupled with 
collaboration across the organization led to strong outcomes – including the retention of customer relationships and a strengthened 
deposit base – as the regional banking section begins to normalize. 

Delivering Solid Financial Performance
Although the economic environment remains uncertain, we observed a cautiously more optimistic trend in customer sentiment at 
year-end as we believe many expect less rate pressure in 2024. We continue our commitment to support our customers and remain 
confident we will grow alongside them as the economy strengthens. 

With 7% growth, we produced our highest level of average annual loans despite deliberate optimization efforts in the second half of 
the year. We focused on deposits and were pleased to see stabilization following industry events and ongoing quantitative tightening. 
We delivered record net interest income aided by higher rates and loan balances. Our credit quality remained strong, with net charge-
offs well below historical averages. In recognition of the new industry funding paradigm, actions to recalibrate our expense base are 
designed to benefit our future as we create capacity for investment and enhance returns.

Despite the industry volatility in 2023, our core business remains unchanged. Our highly regarded approach to credit continued to 
perform well. Tailored products are designed to meet the needs of our customers - enhancing revenue and retention. Our deposit 
profile has long been a strength, and we expect our investments in products and small business will make this core funding source 
even more compelling. We produced a strong year in the face of adversity.    

Small Business is Big Business
Comerica has excelled at supporting the needs of businesses and, in 2023, we further prioritized delivering impactful banking 
solutions to small businesses. These institutions serve as the economic engines of our local communities, and that is why we 
established a three-year, $5 billion small business lending commitment, first announced in May 2021. We proudly exceeded 100% of 
that commitment in 2023, delivering meaningful funding to more than 15,000 small businesses. Surpassing our commitment is the 
result of a collaborative effort led by our Small Business Banking, Community Development and Business Banking teams, providing 
customers and communities with much-needed access to capital. 

We launched unique offerings in our Dallas/Fort Worth market that deliver critical resources to entrepreneurs and business owners, 

enhancing our services for small businesses. To help 
them grow, we introduced: 

•  Comerica SmallBizCo-op™: This program 
provides a set of free and unique service 
offerings designed to help small businesses 
grow and thrive. Small business clients can 
leverage the opportunity to engage clients 
or reward colleagues through our sports 
ticket inventory, capitalize on free advertising 
support from Comerica’s inventory and 
discounts on office supplies and technology.

•  Comerica CoWorkSpaces™: We offer 

complimentary office and meeting space in 
select banking centers exclusively for small 
business customers. Through a $3 million 
investment, we have transformed nearly 
10,000 square feet into unique resources for 
small business customers to help meet their 
growing needs.

In 2023, Comerica introduced Comerica CoWorkSpaces™ as part of its latest 
services tailored for small business customers. These spaces provide Comerica 
small business customers with free access to office and meeting space.

•  SizeUp by Comerica: We help small businesses leverage our data, tapping into competitive market research and insights to 
support informed business decisions. From creating benchmarks to understanding consumer spending, we are bringing big 
business resources to our small business customers. 

The Small Business Banking team leads our support for small business clients and remains dedicated to meeting unmet customer 
needs, serving our communities and driving growth. This team supports 80% of banking centers across all markets and reaches 

92% of locations serving low- to moderate-income 
communities. 

One of our newest small business resources, 
Comerica BusinessHQ, is empowering underserved 
communities by providing access to capital and other 
meaningful resources. Leveraging idle real estate, 
we opened the doors to the state-of-the-art facility 
that provides high-need, high-opportunity small 
businesses in the Southern sector of Dallas with the 
necessary tools to develop, grow and endure. The 
space offers small business owners and entrepreneurs 
flexible, temporary workspaces and turnkey access 
to high-speed Wi-Fi; information security and privacy; 
printing; scanning; large scale projection video 
conferencing rooms; as well as space furnished 
with equipment for small-scale content creation. 
We are extremely proud of this pilot project which 
has redefined how a bank can serve the needs of its 
community.

Comerica executives join representatives from the Dallas Black Chamber 
of Commerce during the official ribbon cutting ceremony of Comerica 
BusinessHQ. The new state-of-the-art facility serves as a collaborative space 
providing integral services to small businesses in the Southern sector of Dallas. 

Investing in Wealth Management 
We have a client-centric, high-caliber, planning-based approach to serving our Wealth Management clients. In 2023, we deepened 
our commitment by adding new teams and an enhanced array of products. We increased our Wealth Management presence with 
the addition of a new private wealth management team in Southern California, consisting of 11 experienced professionals, with 
approximately $3 billion in assets. 

We also completed our new investment program: Comerica Financial Advisors powered by Ameriprise Financial. Through this strategic 
relationship, we will grow our business by providing financial advisors and clients with an enhanced suite of services, including 
technological enhancements, varied product offerings, around-the-clock access to support services, and much more. We will also 
enhance our risk management culture and engage new and experienced talent, creating greater coverage levels for banking centers to 

 
better serve our retail partners.

Leading the Way
Having the right leadership in place is critical to our success, especially as you look at events like the recent industry disruption and 
the ongoing evolution of the regulatory landscape. In 2023, we attracted veteran banking leaders in the areas of Compliance and Risk 
Management to complement our tenured, diverse executive leadership team and meaningfully enhance and advance foundational 
capabilities across the bank. 

We also added select strategic revenue leaders in Middle Market & Business Banking, National & Specialty Businesses and Payments to 
our Management Executive Committee further amplifying the voice of the customer in our strategic decision making. 

Our Board of Directors also experienced growth in 2023 with the addition of four diverse, experienced executive leaders from various 
industries. Our Board continues its crucial role in our efforts to deliver growth for our shareholders, colleagues and communities.

Growing Presence in Newer Markets
We continued investments to selectively broaden Comerica’s presence beyond the primary markets of Michigan, Texas, California, 
Arizona and Florida, bringing our core businesses to rapidly growing geographic markets aligned with our strategy. We continued to move 
forward with our expansion efforts in the Southeast and Mountain West Markets. 

We established an office in Winston-Salem, North Carolina, to accompany our market headquarters location in Raleigh and our office 
in Charlotte. A catalyst to our success in the Southeast has been our established Florida market, allowing us to attract experienced 
Commercial Banking, Wealth and Private Banking talent to engage new clients in the region. 

In the Mountain West, we established the role of Colorado Market President to go along with a team of banking professionals to 
develop commercial lending opportunities and engage with area business leaders. Based out of Denver, the team built and added new 
relationships, establishing a strong pipeline.

Ongoing Technology and Product Modernization
We live in an increasingly complex digital ecosystem, and exceeding customer expectations related to technology and products remains 
paramount. We continued modernizing our core infrastructure, with more than 75% of business applications now running on Cloud 
platforms, strengthening cybersecurity and resilience to threats. We also upgraded platforms for customer-facing technologies such as 
Treasury Management resources and the Comerica Mobile App.

We continue to nimbly deliver products and ongoing enhancements to customers. In 2023, we delivered intuitive, convenient 
experiences for small business customers through the successful launch of Convenient Capital - a fully digital, end-to-end lending 
platform – and Zelle for Small Business, which enables faster payments for small businesses. 

In addition, we launched Comerica Maximize, the latest solution in our growing suite of value-add offerings to help business customers of 
all sizes save time and maximize their cash. Comerica Maximize combines an interest-bearing checking account with cash management 
solutions where customers earn interest income while growing and protecting their businesses with basic treasury services.

Optimizing our Banking Center Network
In December 2023, we completed the rollout of Retail Reimagined to banking centers across all our markets. Through Retail 
Reimagined, we will compete, thrive and lead in a new era of hyper-competitive banking and elevated consumer/business expectations. 
We clarified colleague roles, improved processes, invested in marketing and technology, and built capabilities to deepen and grow our 
customer base. The results include better sales productivity. 

We continue to update banking center networks to ensure we have the right number of banking centers in the communities we serve, 
based on population and traffic patterns. We modernized several physical banking center locations as part of an integrated channel 
approach, completing 23 banking center renovations with three relocations in San Antonio, Texas; Arlington, Texas; and greater Los 
Angeles. The updated locations have a clean, modern layout and align with our updated branding as well as enhanced operational 
efficiencies, amenities and technology.

From the Inside Out
Comerica’s strong workforce and unique company culture are central to our success, and we are committed to providing resources, 
spaces and opportunities that attract and retain top talent. To maintain our engaged and inclusive culture, we offer numerous 
professional development programs and opportunities, a competitive and cost-effective benefits package, and a hybrid work 
environment. All this empowers colleagues to work effectively and productively to execute our objectives while enhancing our culture. 
Our comprehensive approach to supporting colleagues and strong culture earned us “Top Workplaces 2023” awards from The Dallas

Honoring our Past While Shaping the Future
After a distinctive 2023, we look forward to all that’s ahead in 2024. To guide our success, we identified clear goals aimed at driving solid

also proud to celebrate Comerica’s 175th anniversary! This is a significant milestone, and we look forward to recognizing our storied 
history and legacy across our markets throughout the year.

I would like to thank each of my Comerica colleagues for their tireless contributions in 2023, and for their commitment as we set our

colleagues across our organization. Through good and challenging times, they drive our company forward and continue to demonstrate 
an unwavering commitment to raising expectations. 

Finally, we remain incredibly grateful for our shareholders, whose support is vital. We are concentrating on sustainably increasing

Item 1. Business.

GENERAL

Comerica  Incorporated  (“Comerica”)  is  a  financial  services  company,  incorporated  under  the  laws  of  the  State  of 
Delaware in 1973, and headquartered in Dallas, Texas. Based on total assets as reported in the most recently filed Consolidated 
Financial Statements for Bank Holding Companies (FR Y-9C), it was among the 25 largest commercial United States (“U.S.”) 
financial  holding  companies.  As  of  December  31,  2023,  Comerica  owned  directly  or  indirectly  all  the  outstanding  common 
stock  of  2  active  banking  subsidiaries  (Comerica  Bank,  a  Texas  banking  association,  and  Comerica  Bank  &  Trust,  National 
Association)  as  well  as  non-banking  subsidiaries.  At  December  31,  2023,  Comerica  had  total  assets  of  approximately  $85.8 
billion,  total  deposits  of  approximately  $66.8  billion,  total  loans  of  approximately  $52.1  billion  and  shareholders’  equity  of 
approximately $6.4 billion.

Comerica has strategically aligned its operations into three major business segments: the Commercial Bank, the Retail 

Bank, and Wealth Management. In addition to the three major business segments, Finance is also reported as a segment.

Comerica  operates  in  five  primary  geographic  markets  -  Texas,  California,  Michigan,  Arizona  and  Florida  -  and 

secondarily in several mountain, southeastern, and other states, and in Canada and Mexico. 

In 2023, Comerica announced a strategic relationship with Ameriprise to become Comerica’s new investment program 
provider.  As  such,  Comerica  transitioned  support  of  specific  insurance,  brokerage  and  investment  advisory  activities  to 
Ameriprise.  The  new  name  representing  this  strategic  relationship  is  Comerica  Financial  Advisors,  powered  by  Ameriprise 
Financial.

We provide information about the net interest income and noninterest income we received from our various classes of 
products and services: (1) under the caption, “Analysis of Net Interest Income” in the Financial Section of this report; (2) under 
the caption “Rate/Volume Analysis” in the Financial Section of this report; and (3) under the caption “Noninterest Income” in 
the Financial Section of this report.

COMPETITION

The financial services business is highly competitive. Comerica and its subsidiaries mainly compete in their primary 
and  secondary  geographic  markets,  and  also  compete  throughout  the  continental  U.S.,  Mexico  and  Canada  as  they  pursue 
certain  businesses  on  a  national  scale  that  fall  outside  of  the  primary  markets,  such  as  U.S.  Banking,  Mortgage  Banker, 
Environmental Services and National Dealer Services. They have strategically placed offices in faster growing markets where 
there is a concentration of customers and industries they serve. Comerica has established commercial offices in North Carolina 
and South Carolina, private banking offices in Georgia and made investments in the Mountain West region of the United States. 

Comerica  is  subject  to  competition  with  respect  to  various  products  and  services,  including,  without  limitation, 
commercial  products  such  as  loans  and  lines  of  credit,  deposits,  cash  management  (including  payments  solutions  and  card 
services),  capital  markets,  international  trade  finance,  letters  of  credit,  foreign  exchange  management  and  loan  syndications; 
consumer products such as loans, deposits and origination of mortgage loans and credit cards; and wealth management services 
such  as  comprehensive  financial  planning,  trust  and  fiduciary  services,  investment  management  and  advisory,  brokerage, 
private banking, and business transition planning services. 

Comerica competes largely on the basis of industry expertise, the range of products and services offered, pricing and 
reputation, convenience, quality of service, responsiveness to customer needs and the overall customer relationship. Comerica's 
competitors  include  financial  institutions  of  all  sizes.  Some  of  Comerica's  larger  competitors,  including  certain  nationwide 
banks that have a significant presence in Comerica's markets, may have a broader array of products and structure alternatives 
and, due to their size, may more easily absorb credit losses. Some of Comerica's competitors (larger or smaller) may have more 
liberal lending policies and aggressive pricing standards for loans, deposits and services. 

Increasingly, Comerica competes with other companies based on financial technology and capabilities, such as mobile 
banking  applications  and  funds  transfer.  Further,  Comerica's  competitors  may  be  subject  to  significantly  different  or  lesser 
regulation due to their asset size or types of products offered. Some competitors may also have the ability to more efficiently 
utilize resources to comply with regulations or may be able to more effectively absorb the cost of regulations. 

In  addition  to  banks,  Comerica  and  its  banking  subsidiaries  also  face  competition  from  financial  intermediaries, 
including  savings  and  loan  associations,  consumer  and  commercial  finance  companies,  leasing  companies,  venture  capital 
funds,  credit  unions,  investment  banks,  insurance  companies  and  securities  firms.  Competition  among  providers  of  financial 
products and services continues to increase as technology advances have lowered the barriers to entry for financial technology 
companies,  with  customers  having  the  opportunity  to  select  from  a  growing  variety  of  traditional  and  nontraditional 
alternatives, including crowdfunding, digital wallets and money transfer services. The ability of non-banks to provide services 
previously  limited  to  traditional  banks  has  intensified  competition.  Because  non-banks  are  not  subject  to  many  of  the  same 

1

regulatory  restrictions  as  banks  and  bank  holding  companies,  they  can  often  operate  with  greater  flexibility  and  lower  cost 
structures. 

Finally, the industry continues to consolidate, which eliminates some regional and local institutions, while potentially 
strengthening acquirers. Comerica believes that the level of competition in all geographic markets will continue to increase in 
the future. 

SUPERVISION AND REGULATION

Banks, bank holding companies, and other financial institutions are highly regulated at both the state and federal level. 
Comerica is subject to supervision and regulation at the federal level by the Board of Governors of the Federal Reserve System 
through  the  Federal  Reserve  Bank  of  Dallas  (“FRB”)  pursuant  to  the  Bank  Holding  Company  Act  of  1956,  as  amended. 
Comerica  Bank (the "Bank") is chartered by the State of Texas and at the state level is supervised and regulated by the Texas 
Department  of  Banking  under  the  Texas  Finance  Code  and  the  Texas  Administrative  Code.  The  Bank  has  elected  to  be  a 
member of the Federal Reserve System under the Federal Reserve Act and, consequently, is supervised and regulated by the 
FRB. Comerica Bank & Trust, National Association is federally chartered and is subject to supervision and regulation by the 
Office  of  the  Comptroller  of  the  Currency  (“OCC”)  pursuant  to  the  National  Bank  Act.  Comerica  Bank  &  Trust,  National 
Association, by virtue of being a national bank, is also a member of the Federal Reserve System. Furthermore, given that the 
Bank  is  a  bank  with  assets  in  excess  of  $10  billion,  it  is  subject  to  supervision  and  regulation  by  the  Consumer  Financial 
Protection Bureau ("CFPB") for purposes of assessing compliance with federal consumer financial laws. The Bank's deposits, 
and those of Comerica Bank & Trust, National Association, are insured by the Deposit Insurance Fund (“DIF”) of the Federal 
Deposit Insurance Corporation (“FDIC”) to the fullest extent provided by law, and therefore the Bank and Comerica Bank & 
Trust, National Association are each also subject to regulation by the FDIC. Certain transactions executed by the Bank are also 
subject  to  regulation  by  the  U.S.  Commodity  Futures  Trading  Commission  (“CFTC”).  The  Department  of  Labor  (“DOL”) 
regulates financial institutions providing services to plans governed by the Employee Retirement Income Security Act of 1974. 
The  Bank’s  Canada  branch  is  supervised  by  the  Office  of  the  Superintendent  of  Financial  Institutions  and  its  Mexico 
representative office is also supervised by the Banco de México. The Bank is also registered in the Cayman Islands and subject 
to supervision by the Cayman Islands Monetary Authority. 

The  FRB  supervises  non-banking  activities  conducted  by  companies  directly  and  indirectly  owned  by  Comerica.  In 
addition,  Comerica’s  non-banking  subsidiaries  are  subject  to  supervision  and  regulation  by  various  state,  federal  and  self-
regulatory agencies, including, but not limited to, the Financial Industry Regulatory Authority, Inc. (“FINRA”), the Department 
of Licensing and Regulatory Affairs of the State of Michigan, the Municipal Securities Rulemaking Board (“MSRB”) and the 
Securities  and  Exchange  Commission  (“SEC”)  (in  the  case  of  Comerica  Securities,  Inc.);  the  Department  of  Insurance  and 
Financial  Services  of  the  State  of  Michigan  (in  the  case  of  Comerica  Insurance  Services,  Inc.);  and  the  DOL  (in  the  case  of 
Comerica Securities, Inc. and Comerica Insurance Services, Inc.).

Both the scope of the laws and regulations and intensity of supervision to which banks', bank holding companies' and 
financial  institutions'  businesses  are  subject  continue  to  increase  in  response  to  the  2007-2008  financial  crisis,  subsequent 
events,  and  other  factors  such  as  technological,  economic  and  market  changes.  Many  regulatory  changes  have  occurred  as  a 
result  of  the  Dodd-Frank  Wall  Street  Reform  and  Consumer  Protection  Act  of  2010  (the  “Dodd-Frank  Act”)  and  its 
implementing  regulations,  most  of  which  are  now  in  place.  In  2018,  with  the  passage  of  the  Economic  Growth,  Regulatory 
Relief  and  Consumer  Protection  Act  (“EGRRCPA”),  as  described  below,  there  was  some  recalibration  of  the  post-financial 
crisis framework; however, banks', bank holding companies' and financial institutions' businesses remain subject to extensive 
regulation  and  supervision.  The  failure  of  certain  banks  in  the  spring  of  2023  played  a  role  in  another  increase  in  bank 
regulation, at least some of which could apply to Comerica.

The  Community  Reinvestment  Act  of  1977  (“CRA”)  requires  U.S.  banks  to  help  serve  the  credit  needs  of  their 
communities. If any bank were to receive a rating under the CRA of less than “Satisfactory,” the bank would be prohibited from 
engaging  in  certain  activities.  Comerica's  current  CRA  rating  is  "Outstanding."  The  CRA  regulations  were  substantially 
amended in 2023, which may affect future compliance.

Comerica is also subject to the disclosure and regulatory requirements of the Securities Act of 1933, as amended, and 
the Securities Exchange Act of 1934, as amended, both as administered by the SEC, as well as the rules of the New York Stock 
Exchange.

Described  below  are  material  elements  of  selected  laws  and  regulations  applicable  to  Comerica  and  its  subsidiaries. 
The descriptions are not intended to be complete and are qualified in their entirety by reference to the full text of the statutes 
and regulations described. Changes in applicable law or regulation, and in their application by regulatory agencies, cannot be 
predicted, but they may have a material effect on the business of Comerica and its subsidiaries.

Economic Growth, Regulatory Relief and Consumer Protection Act and Recent Developments

On  May  24,  2018,  EGRRCPA  was  signed  into  law.  Among  other  regulatory  changes,  EGRRCPA  amended  various 
sections of the Dodd-Frank Act, including section 165 of Dodd-Frank Act, which was revised to raise the asset thresholds for 
determining  the  application  of  enhanced  prudential  standards  for  bank  holding  companies.  Under  EGRRCPA  bank  holding 
companies with less than $100 billion of consolidated assets, such as Comerica, became exempt from all of the Dodd-Frank 
enhanced  prudential  standards,  except  risk  committee  requirements.  As  a  result,  Comerica  currently  is  not  subject  to  the 
remaining Dodd-Frank Act enhanced prudential standards or certain capital and liquidity rules to large bank holding companies 
and depository institutions (the “Tailoring Rules”). 

Should Comerica meet or cross the $100 billion asset threshold and thus become a Category IV institution it will be 
subject to additional and more stringent regulation, which includes, but is not limited to, enhanced prudential standards for U.S. 
banking  organizations  with  $100  to  $250  billion  of  consolidated  assets.  In  addition,  Comerica  would  be  required  to  pay  the 
supervision and regulation fee assessment under the Dodd-Frank Act. 

On July 27, 2023, the FRB, the FDIC, and the OCC issued a proposal, referred to as “Basel III Endgame,” that would 
result  in  significant  changes  to  the  U.S.  regulatory  capital  rules  under  EGRRCPA  for  banking  organizations  with  total 
consolidated  assets  of  $100  billion  or  more.  Comerica's  total  consolidated  assets  are  below  this  $100  billion  threshold,  but 
Comerica  continues  to  invest  in  potential  preparation  should  it  meet  that  threshold  or  regulators  lower  that  threshold.  If 
Comerica becomes subject to these requirements or becomes subject to any other new laws or regulations related to capital and 
liquidity, such requirements could limit Comerica’s ability to pay dividends or make share repurchases or require Comerica to 
reduce  business  levels  or  to  raise  capital,  which  would  have  a  material  adverse  effect  on  Comerica's  financial  condition  and 
results of operations.

In  addition  to  laws  and  regulations  focusing  principally  on  asset  thresholds,  examination  ratings  also  can  affect 
Comerica. Adverse examination findings can result in confidential or public enforcement actions, which can affect fees, costs, 
operational requirements, and growth initiatives, at both Comerica and each of its subsidiary banks.

Requirements for Approval of Activities and Acquisitions

The  Gramm-Leach-Bliley  Act  expanded  the  activities  in  which  a  bank  holding  company  registered  as  a  financial 
holding  company  can  engage.  A  financial  holding  company  may  affiliate  with  securities  firms  and  insurance  companies  and 
engage in activities that are financial in nature or incidental or complementary to activities that are financial in nature. Activities 
that  are  "financial  in  nature"  include,  but  are  not  limited  to:  securities  underwriting;  securities  dealing  and  market  making; 
sponsoring  mutual  funds  and  investment  companies  (subject  to  regulatory  requirements  described  below);  insurance 
underwriting and agency; merchant banking,; and activities that the FRB determines, in consultation with the Secretary of the 
United States Treasury, to be financial in nature or incidental to a financial activity. "Complementary activities" are activities 
that the FRB determines upon application to be complementary to a financial activity and that do not pose a substantial risk to 
the safety or soundness of depository institutions or the financial system generally. In order to exercise the full benefits of its 
status as a bank holding company and a financial holding company, Comerica and each of its depository institution subsidiaries 
must be considered “well capitalized” and “well managed.” If at any time a financial holding company or any subsidiary bank is 
not considered “well capitalized” or “well managed” under applicable regulatory standards, the law and the FRB limit its ability 
to conduct the broader financial activities permissible for financial holding companies, and impose limitations or conditions on 
its conduct or activities or those of its bank and non-bank affiliates. If the deficiencies persist, the FRB could order the financial 
holding  company  to  divest  any  subsidiary  bank  or  to  cease  engaging  in  any  activities  permissible  for  financial  holding 
companies that are not permissible for bank holding companies, or the financial holding company could elect to conform its 
non-banking activities to those permissible for a bank holding company that is not also a financial holding company. Adverse 
examinations at the bank-level also could increase costs and limit activities and growth of Comerica Bank & Trust, National 
Association and Bank and its subsidiaries.

Federal  and  state  laws  impose  notice  and  approval  requirements  for  mergers  and  acquisitions  of  other  depository 
institutions or bank holding companies. In many cases, no FRB approval is required for a financial holding company to acquire 
a company engaged in activities that are financial in nature or incidental to activities that are financial in nature, as determined 
by the FRB. Prior approval is required before a financial holding company may acquire the beneficial ownership or control of 
more  than  5%  of  any  class  of  voting  shares  or  substantially  all  of  the  assets  of  a  bank  holding  company  (including  another 
financial holding company) or a bank. In considering applications for approval of acquisitions, the banking regulators may take 
several factors into account, including whether the financial holding company and its subsidiaries are well capitalized and well 
managed, are in compliance with anti-money laundering laws and regulations, or have CRA ratings of less than “Satisfactory.” 
The Bank's current CRA rating is "Outstanding."

3

Acquisitions of Ownership of Comerica

Acquisitions  of  Comerica’s  voting  stock  above  certain  thresholds  are  subject  to  prior  regulatory  notice  or  approval 
under federal banking laws, including the Bank Holding Company Act of 1956 and the Change in Bank Control Act of 1978. 
Under the Change in Bank Control Act, a person or entity generally must provide prior notice to the FRB before acquiring the 
power to vote 10% or more of a subject company's outstanding common stock. Investors should be aware of these requirements 
when acquiring shares of Comerica’s stock.

Capital and Liquidity

Comerica and its bank subsidiaries are subject to risk-based capital requirements and guidelines imposed by the FRB, 
FDIC and/or the OCC. In calculating risk-based capital requirements, a depository institution’s or holding company’s assets and 
certain specified off-balance sheet items (such as unused commitments and standby letters of credit) are assigned to various risk 
categories  defined  by  those  agencies,  each  weighted  differently  based  on  the  level  of  risk  that  is  ascribed  to  such  assets  or 
commitments,  based  on  counterparty  type,  asset  class  and  maturity.  A  depository  institution’s  or  bank  holding  company’s 
capital is divided into three tiers: Common Equity Tier 1 (“CET1”), additional Tier 1, and Tier 2. CET1 capital predominantly 
includes common shareholders’ equity, less certain deductions for goodwill, intangible assets and deferred tax assets that arise 
from  net  operating  losses  and  tax  credit  carry-forwards,  if  any.  Additional  Tier  1  capital  primarily  includes  any  outstanding 
noncumulative  perpetual  preferred  stock  and  related  surplus.  Comerica  has  also  made  the  election  to  permanently  exclude 
accumulated  other  comprehensive  income  related  to  debt  securities  classified  as  available-for-sale,  cash  flow  hedges,  and 
defined  benefit  postretirement  plans  from  CET1  capital.  Additional  Tier  1  capital  primarily  includes  any  outstanding 
noncumulative  perpetual  preferred  stock  and  related  surplus.  Tier  1  capital  is  equal  to  CET1  capital  plus  additional  Tier  1 
capital.  Tier  2  capital  primarily  includes  qualifying  subordinated  debt  and  qualifying  allowance  for  credit  losses.  More 
information is set forth under the caption “Capital” in the Financial Section of this report. Total capital is the amount equal to 
Tier 1 capital plus Tier 2 Capital. 

Entities that engage in trading activities that exceed specified levels also are required to maintain capital to account for 
market risk. Market risk includes changes in the market value of trading account, foreign exchange, and commodity positions, 
whether resulting from broad market movements (such as changes in the general level of interest rates, equity prices, foreign 
exchange rates, or commodity prices) or from position specific factors. From time to time, Comerica’s trading activities may 
exceed  specified  regulatory  levels,  in  which  case  Comerica  adjusts  its  risk-weighted  assets  to  account  for  market  risk  as 
required.

Bank  holding  companies  and  banks  are  currently  required  to  maintain  a  CET1  capital  ratio,  Tier  1  capital  ratio  and 
total capital ratio equal to at least 4.5 percent, 6 percent and 8 percent of their total risk-weighted assets (including certain off-
balance-sheet  items,  such  as  unused  commitments  and  standby  letters  of  credit),  respectively.  Comerica  and  its  bank 
subsidiaries are also required to maintain a minimum capital conservation buffer of 2.5 percent in order to avoid restrictions on 
capital distributions and discretionary bonuses, and to maintain a minimum “leverage ratio” (Tier 1 capital to non-risk-adjusted 
average total assets) of 4 percent.

To be well capitalized, banks are required to maintain a leverage ratio, CET1 capital ratio, Tier 1 capital ratio and total 
capital  ratio  equal  to  at  least  5.0  percent,  6.5  percent,  8.0  percent  and  10.0  percent,  respectively.  For  purposes  of  the  FRB’s 
Regulation  Y,  including  determining  whether  a  bank  holding  company  meets  the  requirements  to  be  a  financial  holding 
company, bank holding companies must maintain a Tier 1 capital ratio of at least 6.0 percent and a total capital ratio of at least 
10.0  percent  to  be  well  capitalized.  The  FRB  may  require  bank  holding  companies  to  maintain  capital  ratios  substantially  in 
excess  of  mandated  minimum  levels,  depending  upon  general  economic  conditions  and  a  bank  holding  company’s  particular 
condition, risk profile and growth plans.

Failure to be well capitalized or to meet minimum capital requirements could result in certain mandatory and possible 
additional  discretionary  actions  by  regulators,  including  restrictions  on  the  ability  to  pay  dividends  or  otherwise  distribute 
capital or to receive regulatory approval of applications, or other restrictions on growth.

Additional information on the calculation of Comerica’s and its bank subsidiaries’ CET1 capital, Tier 1 capital, total 
capital and risk-weighted assets is set forth in the “Capital” section in the Financial Section of this report and Note 20 of the 
Notes to Consolidated Financial Statements in the Financial Section of this report.

Federal Deposit Insurance Corporation Improvement Act 

The  Federal  Deposit  Insurance  Corporation  Improvement  Act  (“FDICIA”)  requires,  among  other  things,  the  federal 
banking agencies to take “prompt corrective action” with respect to depository institutions that do not meet certain minimum 
capital  requirements.  FDICIA  establishes  five  capital  tiers:  “well  capitalized,”  “adequately  capitalized,”  “undercapitalized,” 
“significantly undercapitalized” and “critically undercapitalized.” An institution that fails to remain well capitalized becomes 
subject  to  a  series  of  restrictions  that  increase  in  severity  as  its  capital  condition  weakens.  Such  restrictions  may  include  a 
prohibition on capital distributions, restrictions on asset growth or restrictions on the ability to receive regulatory approval of 
applications.  The  FDICIA  also  provides  for  enhanced  supervisory  authority  over  undercapitalized  institutions,  including 
authority for the appointment of a conservator or receiver for the institution.

As an additional means to identify problems in the financial management of depository institutions, FDICIA requires 
federal bank regulatory agencies to establish certain non-capital-based safety and soundness standards for institutions any such 
agency  supervises.  The  standards  relate  generally  to,  among  others,  earnings,  liquidity,  operations  and  management,  asset 
quality,  various  risk  and  management  exposures  (e.g.,  credit,  operational,  market,  interest  rate,  etc.)  and  executive 
compensation. The agencies are authorized to take action against institutions that fail to meet such standards. 

FDICIA also contains a variety of other provisions that may affect the operations of depository institutions including 
reporting  requirements,  regulatory  standards  for  real  estate  lending,  “truth  in  savings”  provisions,  the  requirement  that  a 
depository institution give 90 days prior notice to customers and regulatory authorities before closing any domestic branch, and 
a prohibition on the acceptance or renewal of brokered deposits by depository institutions that are not well capitalized or are 
adequately capitalized and have not received a waiver from the FDIC.

Dividends

Comerica Incorporated is a legal entity separate and distinct from its banking and other subsidiaries. Since Comerica’s 
consolidated  net  income  and  liquidity  consists  largely  of  net  income  of  and  dividends  received  from  Comerica’s  bank 
subsidiaries,  Comerica’s  ability  to  pay  dividends  and  repurchase  shares  depends  upon  its  receipt  of  dividends  from  these 
subsidiaries.  There  are  statutory  and  regulatory  requirements  applicable  to  the  payment  of  dividends  by  subsidiary  banks  to 

5

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Comerica,  as  well  as  by  Comerica  to  its  shareholders.  Certain,  but  not  all,  of  these  requirements  are  discussed  below.  No 
assurances can be given that Comerica’s bank subsidiaries will, in any circumstances, pay dividends to Comerica.

Banks are required by federal law to obtain the prior approval of the FRB and/or the OCC, as the case may be, for the 
declaration  and  payment  of  dividends,  if  the  total  of  all  dividends  declared  by  the  board  of  directors  of  such  bank  in  any 
calendar year will exceed the total of (i) such bank's net income (as defined and interpreted by regulation) for that year plus 
(ii) the retained net income (as defined and interpreted by regulation) for the preceding two years, less any required transfers to 
surplus or to fund the retirement of preferred stock. At January 1, 2024, Comerica's subsidiary banks could declare aggregate 
dividends  of  approximately  $400  million  from  retained  net  profits  of  the  preceding  two  years.  Comerica's  subsidiary  banks 
declared dividends of $675 million in 2023, $1.0 billion in 2022 and $852 million in 2021. 

Furthermore, federal regulatory agencies can prohibit a bank or bank holding company from paying dividends under 
circumstances in which such payment could be deemed an unsafe and unsound banking practice. Under the FDICIA “prompt 
corrective  action”  regime  discussed  above,  a  bank  is  specifically  prohibited  from  paying  dividends  to  its  parent  company  if 
payment would result in the bank becoming “undercapitalized.” In addition, the Bank is also subject to limitations under Texas 
state  law  regarding  the  amount  of  earnings  that  may  be  paid  out  as  dividends  to  Comerica  and  requires  prior  approval  for 
payments of dividends that exceed certain levels. 

FRB  supervisory  guidance  generally  provides  that  a  bank  holding  company  should  not  maintain  its  existing  rate  of 
dividends on  common stock unless (1)  the organization’s  net  income  over  the past year has been  sufficient  to  fully  fund the 
dividends, (2) the prospective rate of earnings retention appears consistent with the organization's capital needs, asset quality 
and overall financial condition and (3) the organization will continue to meet minimum required capital adequacy ratios. The 
supervisory guidance also provides that a bank holding company should inform the FRB reasonably in advance of declaring or 
paying a dividend that exceeds earnings for the period for which the dividend is being paid or that could result in a material 
adverse change to the bank holding company’s capital structure. The guidance suggests that bank holding companies consult 
with  the  FRB  before  redeeming  or  repurchasing  capital  instruments,  or  materially  increasing  dividends.  In  addition,  FRB 
regulation  requires  bank  holding  companies  to  provide  notice  to  or  obtain  approval  from  the  FRB  prior  to  purchasing  or 
redeeming equity securities under certain circumstances.

Transactions with Affiliates

Federal  banking  laws  and  regulations  impose  qualitative  standards  and  quantitative  limitations  upon  certain 
transactions between a bank and its affiliates, on the one hand, and Comerica’s affiliate insured depository institutions, on the 
other. For example, Section 23A of the Federal Reserve Act limits the aggregate outstanding amount of any insured depository 
institution’s loans and other “covered transactions” with any particular nonbank affiliate (including financial subsidiaries) to no 
more  than  10%  of  the  institution’s  total  capital  and  limits  the  aggregate  outstanding  amount  of  any  insured  depository 
institution’s  covered  transactions  with  all  of  its  nonbank  affiliates  to  no  more  than  20%  of  its  total  capital.  “Covered 
transactions” are defined by statute to include (i) a loan or extension of credit to an affiliate, (ii) a purchase of securities issued 
by  an  affiliate,  (iii)  a  purchase  of  assets  (unless  otherwise  exempted  by  the  FRB)  from  the  affiliate,  (iv)  the  acceptance  of 
securities issued by the affiliate as collateral for a loan, (v) the issuance of a guarantee, acceptance or letter of credit on behalf 
of an affiliate and (vi) securities borrowing or lending transactions and derivative transactions with an affiliate, to the extent that 
either  causes  a  bank  or  its  affiliate  to  have  credit  exposure  to  the  securities  borrowing/lending  or  derivative  counterparty. 
Section  23A  of  the  Federal  Reserve  Act  also  generally  requires  that  an  insured  depository  institution’s  loans  to  its  nonbank 
affiliates  be,  at  a  minimum,  100%  secured,  and  Section  23B  of  the  Federal  Reserve  Act  generally  requires  that  an  insured 
depository institution’s transactions with its nonbank affiliates be on terms and under circumstances that are substantially the 
same or at least as favorable as those prevailing for comparable transactions with nonaffiliates.

Loans to Insiders

Federal Reserve Act and Regulation O restrictions on loans to directors, executive officers, principal stockholders and 
their  related  interests  (collectively,  “insiders”)  apply  to  all  insured  institutions  and  their  subsidiaries  and  holding  companies. 
These restrictions include conditions that must be met before insider loans can be made, limits on loans to an individual insider 
and an aggregate limitation on all loans to insiders and their related interests. These loans cannot exceed the institution’s total 
unimpaired capital and surplus, and the Federal Reserve Board may determine that a lesser amount is appropriate. Insiders are 
subject  to  enforcement  actions  for  knowingly  accepting  loans  in  violation  of  applicable  restrictions.  The  Dodd-Frank  Act 
amended  the  statutes  placing  limitations  on  loans  to  insiders  by  including  credit  exposures  to  the  person  arising  from  a 
derivatives  transaction,  repurchase  agreement,  reverse  repurchase  agreement,  securities  lending  transaction  or  securities 
borrowing transaction between the member bank and the person within the definition of an extension of credit.

Federal Laws Applicable to Credit Transactions

Comerica's loan operations are subject to federal laws and implementing regulations applicable to credit transactions, 
such  as  the  Truth-In-Lending  Act,  the  Home  Mortgage  Disclosure  Act  of  1975,  the  Equal  Credit  Opportunity  Act,  the  Fair 

6

Credit  Reporting  Act  of  1978-,("FCRA"),  the  Fair  Debt  Collection  Practices  Act,  the  Servicemembers  Civil  Relief  Act,  the 
Dodd-Frank Act and rules and regulations of the various federal agencies charged with the responsibility of implementing these 
federal  laws.  State  usury  laws  and  federal  laws  concerning  interest  rates  apply  to  interest  and  other  charges  collected  or 
contracted for by Comerica.

Federal Laws Applicable to Deposit Operations

Comerica's deposit operations are subject to multiple federal laws, including the Right to Financial Privacy Act, the 
Truth in Savings Act and the Electronic Funds Transfer Act. The Dodd-Frank Act amended the Electronic Funds Transfer Act 
to, among other things, give the Federal Reserve Board the authority to establish rules regarding interchange fees charged for 
electronic debit transactions by payment card issuers having assets over $10 billion and to enforce a new statutory requirement 
that such fees be reasonable and proportional to the actual cost of a transaction to the issuer. The FRB is currently soliciting 
comments on a proposal to lower the maximum interchange fee a large debit card issuer can receive for a debit card transaction.

Data Privacy and Cybersecurity Regulation

Comerica is subject to many U.S. federal, U.S. state and international laws and regulations governing consumer data 
privacy  protection,  which  require,  among  other  things,  maintaining  policies  and  procedures  to  protect  the  non-public 
confidential  information  of  customers  and  employees.  The  privacy  provisions  of  the  Gramm-Leach-Bliley  Act  generally 
prohibit financial institutions from disclosing nonpublic personal financial information of consumer customers to third parties 
for certain purposes (primarily marketing) unless customers have the opportunity to “opt out” of the disclosure. Other laws and 
regulations, at the international, federal and state levels, limit Comerica’s ability to share certain information with affiliates and 
non-affiliates for marketing and/or non-marketing purposes, or to contact customers with marketing offers. The Gramm-Leach-
Bliley  Act  also  requires  banks  to  implement  a  comprehensive  information  security  program  that  includes  administrative, 
technical and physical safeguards to ensure the security and confidentiality of customer records and information. 

Federal banking and securities regulations also impose certain requirements on Comerica and its subsidiary banks in 
the event of a cyber- or computer-related security incident. In 2021, the federal banking regulators issued the interagency rule 
for  Computer-Security  Incident  Notification  Requirements  for  Banking  Organizations  and  Their  Service  Providers,  which 
became  effective  on  April  1,  2022.  The  rule  requires  a  bank  to  notify  its  primary  federal  regulator  of  certain  cybersecurity 
incidents within thirty-six (36) hours after the bank determines that a cybersecurity incident has occurred. The rule defines what 
constitutes  a  reportable  incident  and  also  requires  bank  service  providers  to  provide  notice  to  their  respective  banking 
organization  customers  of  certain  cybersecurity  incidents.  The  SEC  recently  issued  a  Cybersecurity  Risk  Management, 
Strategy, Governance, and Incident Disclosure rule, which became effective in December of 2023, and which requires that a 
registered company file a Form 8-K to disclose the occurrence of a material cybersecurity incident within four (4) business days 
of determining that such an incident has occurred. The rule also requires that a registered company include certain information 
regarding its information security  program as part of its  annual Form 10-K filing, including  a discussion of its  processes for 
assessing, identifying, and managing material risks from cybersecurity threats and a description of oversight and management 
of cybersecurity threats at the board and management levels.

Data  privacy  and  data  protection  are  also  areas  of  increasing  state  legislative  focus.  For  example,  the  California 
Consumer Privacy Act of 2018, as amended by the California Privacy Rights Act of 2020 (collectively, the “CCPA”), applies to 
for-profit  businesses  that  conduct  business  in  California  and  meet  certain  revenue  or  data  collection  thresholds.  The  CCPA 
gives consumers the right to request disclosure of information collected about them, and whether that information has been sold 
or shared with others, the right to request deletion of personal information (subject to certain exceptions), the right to opt out of 
the sale of the consumer’s personal information, and the right not to be discriminated against for exercising these rights. The 
CCPA  contains  several  exemptions,  including  an  exemption  applicable  to  information  that  is  collected,  processed,  sold  or 
disclosed pursuant to the Gramm-Leach-Bliley Act. Comerica has a physical footprint in California and is required to comply 
with the CCPA. Similar laws may also be adopted by other states. The federal government may also pass data privacy or data 
protection legislation.

Like  other  lenders,  the  Bank  and  other  of  Comerica’s  subsidiaries  use  credit  bureau  data  in  their  underwriting 
activities. Use of such data is regulated under the FCRA and the FCRA also regulates reporting information to credit bureaus, 
prescreening  individuals  for  credit  offers,  sharing  of  information  between  affiliates,  and  using  affiliate  data  for  marketing 
purposes. Similar state laws may impose additional requirements on Comerica and its subsidiaries.

FDIC Insurance Assessments

The DIF provides deposit insurance coverage for certain deposits up to $250,000 per depositor in each deposit account 
category.  Comerica's  subsidiary  banks  are  subject  to  FDIC  deposit  insurance  assessments  to  maintain  the  DIF.  The  FDIC 
imposes a risk-based deposit premium assessment system, where the assessment rates for an insured depository institution are 
determined by an assessment rate calculator, which is based on a number of elements to measure the risk each institution poses 
to the DIF. The assessment rate is applied to total average assets less tangible equity. Under the current system, premiums are 

7

 
assessed quarterly and could increase if, for example, criticized loans and/or other higher risk assets increase or balance sheet 
liquidity decreases, or a bank's supervisory ratings worsen. For 2023, Comerica’s FDIC insurance expense totaled $180 million.

On October 18, 2022, the FDIC finalized a rule that would increase initial base deposit insurance assessment rates by 2 
basis  points,  beginning  with  the  first  quarterly  assessment  period  of  2023.  The  FDIC,  as  required  under  the  Federal  Deposit 
Insurance Act, established a plan in September 2020 to restore the DIF reserve ratio to meet or exceed the statutory minimum of 
1.35 percent within eight years. This plan did not include an increase in the deposit insurance assessment rate. Based on the 
FDIC’s  recent  projections,  however,  the  FDIC  determined  that  the  DIF  reserve  ratio  is  at  risk  of  not  reaching  the  statutory 
minimum  by  the  statutory  deadline  of  September  30,  2028  without  increasing  the  deposit  insurance  assessment  rates.  The 
increased  assessment  would  improve  the  likelihood  that  the  DIF  reserve  ratio  would  reach  the  required  minimum  by  the 
statutory deadline, consistent with the FDIC’s Amended Restoration Plan. The rule became effective as of January 1, 2023.

As a result of bank failures during early 2023, regulators invoked a "systemic risk exception" in an effort to strengthen 
public confidence in the banking system and protect depositors. As required by law, the FDIC announced that any losses to the 
DIF  to  support  uninsured  depositors  will  be  recovered  by  a  special  assessment  on  banking  organizations.  On  November  16, 
2023,  the  FDIC  adopted  a  final  rule  to  implement  this  special  assessment  based  on  a  banking  organization’s  estimated 
uninsured deposits as of December 31, 2022, excluding the first $5 billion in estimated uninsured deposits. Comerica recorded 
an expense of $109 million as a result of this special assessment during the year ended December 31, 2023. 

Anti-Money Laundering Regulations

Comerica  is  subject  to  several  federal  laws  that  are  designed  to  combat  money  laundering,  terrorist  financing,  and 
transactions with persons, companies or foreign governments designated by U.S. authorities ("AML laws"). This category of 
laws includes the Currency and Foreign Transactions Reporting Act of 170, as amended (the "Bank Secrecy Act"), the Money 
Laundering Control Act, and the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and 
Obstruct Terrorism Act of 2001, or USA PATRIOT Act.

The AML laws and their implementing regulations require insured depository institutions, broker-dealers, and certain 
other  financial  institutions  to  have  policies,  procedures,  and  controls  to  detect,  prevent,  and  report  money  laundering  and 
terrorist  financing.  The  AML  laws  and  their  regulations  also  provide  for  information  sharing,  subject  to  conditions,  between 
federal  law  enforcement  agencies  and  financial  institutions,  as  well  as  among  financial  institutions,  for  counter-terrorism 
purposes.  Federal  banking  regulators  are  required,  when  reviewing  bank  holding  company  acquisition  and  bank  merger 
applications,  to  take  into  account  the  effectiveness  of  the  anti-money  laundering  activities  of  the  applicants.  To  comply  with 
these  obligations,  Comerica  and  its  various  operating  units  have  implemented  appropriate  internal  practices,  procedures,  and 
controls.

The  Anti-Money  Laundering  Act  of  2020  (the  “AML  2020  Act”)  was  enacted  as  part  of  the  National  Defense 
Authorization Act for Fiscal Year 2021. The AML 2020 Act is the most significant revision to the AML laws since the USA 
PATRIOT  Act.  The  AML  2020  Act  clarifies  and  streamlines  the  Bank  Secrecy  Act  and  AML  obligations  in  the  following 
ways: it requires U.S. entities and entities doing business in the United States to report into a national registry maintained by the 
Financial  Crimes  Enforcement  Network  (“FinCEN”)  certain  beneficial  ownership  information,  subject  to  exceptions; 
modernizes the statutory definition of “financial institution” to include (i) entities that provide services involving “value that 
substitutes  for  currency,”  which  includes  stored  value  and  virtual  currencies  and  (ii)  any  person  engaged  in  the  trade  of 
antiquities, including an advisor, consultant or any other person who deals in the sale of antiquities; enhances penalties for Bank 
Secrecy  Act  and  AML  violations,  including  claw  back  of  bonuses;  increases  AML  whistleblower  awards  and  expands 
whistleblower  protections;  requires  the  Secretary  of  the  Treasury  to  establish  and  update  every  four  years  National  AML 
Priorities, which are incorporated into the Bank Secrecy Act compliance programs at financial institutions subject to the Bank 
Secrecy  Act;  among  other  amendments.  Implementing  regulations  concerning  certain  provisions  of  the  AML  2020  Act  have 
been proposed by FinCEN, but not all have been finalized. On September 29, 2022, FinCEN issued a final rule establishing a 
beneficial  ownership  information  reporting  requirement  under  the  Corporate  Transparency  Act  (CTA),  which  was  passed  as 
part of the AML 2020 Act. The rule, which became effective January 1, 2024, requires most entities created in or registered to 
do business in the United States, subject to certain exceptions, to report information about their beneficial owners to FinCEN.

Office of Foreign Assets Control Regulation 

The  Office  of  Foreign  Assets  Control  (“OFAC”)  is  responsible  for  administering  economic  sanctions  that  affect 
transactions  with  designated  foreign  countries,  nationals  and  others,  as  defined  by  various  Executive  Orders  and  Acts  of 
Congress.  OFAC-administered  sanctions  take  many  different  forms.  For  example,  sanctions  may  include:  (1)  restrictions  on 
trade with or investment in a sanctioned country, including prohibitions against direct or indirect imports from and exports to a 
sanctioned country and prohibitions on U.S. persons engaging in financial transactions relating to, making investments in, or 
providing investment-related advice or assistance to, a sanctioned country; and (2) a blocking of assets in which the government 
or  “specially  designated  nationals”  of  the  sanctioned  country  have  an  interest,  by  prohibiting  transfers  of  property  subject  to 
U.S.  jurisdiction  (including  property  in  the  possession  or  control  of  U.S.  persons).  OFAC  also  publishes  lists  of  persons, 
organizations,  and  countries  suspected  of  aiding,  harboring  or  engaging  in  terrorist  acts,  known  as  Specially  Designated 
Nationals  and  Blocked  Persons.  Blocked  assets  (e.g.,  property  and  bank  deposits)  cannot  be  paid  out,  withdrawn,  set  off  or 
transferred in any manner without a license from OFAC. Failure to comply with these sanctions could have serious legal and 
reputational consequences. 

Interstate Banking and Branching

The  Interstate  Banking  and  Branching  Efficiency  Act  (the  “Interstate  Act”),  as  amended  by  the  Dodd-Frank  Act, 
permits  a  bank  holding  company,  with  FRB  approval,  to  acquire  banking  institutions  located  in  states  other  than  the  bank 
holding company's home state without regard to whether the transaction is prohibited under state law, but subject to any state 
requirement that the bank has been organized and operating for a minimum period of time, not to exceed five years, and the 
requirement that the bank holding company, prior to and following the proposed acquisition, control no more than 10 percent of 
the total amount of deposits of insured depository institutions in the U.S. and no more than 30 percent of such deposits in that 
state (or such amount as established by state law if such amount is lower than 30 percent). The Interstate Act, as amended, also 
authorizes banks to operate branch offices outside their home states by merging with out-of-state banks, purchasing branches in 
other  states  and  by  establishing  de  novo  branches  in  other  states,  subject  to  various  conditions.  In  the  case  of  purchasing 
branches in a state in which it does not already have banking operations, de novo interstate branching is permissible if under the 
law of the state in which the branch is to be located, a state bank chartered by that state would be permitted to establish the 
branch.

Source of Strength and Cross-Guarantee Requirements

Federal law and FRB regulations require that bank holding companies serve as a source of strength to each subsidiary 
bank  and  commit  resources  to  support  each  subsidiary  bank.  This  support  may  be  required  at  times  when  a  bank  holding 
company may not be able to provide such support without adversely affecting its ability to meet other obligations. The FRB 
may  require  a  bank  holding  company  to  make  capital  injections  into  a  troubled  subsidiary  bank  and  may  charge  the  bank 
holding company with engaging in unsafe and unsound practices if the bank holding company fails to commit resources to such 
a  subsidiary  bank  or  if  it  undertakes  actions  that  the  FRB  believes  might  jeopardize  the  bank  holding  company’s  ability  to 
commit  resources  to  such  subsidiary  bank.  Under  these  requirements,  Comerica  may  in  the  future  be  required  to  provide 
financial assistance to its subsidiary banks should they experience financial distress. Capital loans by Comerica to its subsidiary 
banks  would  be  subordinate  in  right  of  payment  to  deposits  and  certain  other  debts  of  the  subsidiary  banks.  In  the  event  of 
Comerica’s  bankruptcy,  any  commitment  by  Comerica  to  a  federal  bank  regulatory  agency  to  maintain  the  capital  of  its 
subsidiary banks would be assumed by the bankruptcy trustee and entitled to a priority of payment.

Similarly, under the cross-guarantee provisions of the Federal Deposit Insurance Act, in the event of a loss suffered or 
anticipated by the FDIC (either as a result of the failure of a banking subsidiary or related to FDIC assistance provided to such a 
subsidiary  in  danger  of  failure),  the  other  banking  subsidiaries  may  be  assessed  for  the  FDIC’s  loss,  subject  to  certain 
exceptions.  An  FDIC  cross-guarantee  claim  against  a  depository  institution  is  superior  in  right  of  payment  to  claims  of  the 
holding company and its affiliates against such depository institution.

Supervisory and Enforcement Powers of Federal and State Banking Agencies

The  FRB  and  other  federal  and  state  banking  agencies  have  broad  supervisory  and  enforcement  powers,  including, 
without limitation, and as prescribed to each agency by applicable law, the power to conduct examinations and investigations, 
impose nonpublic supervisory agreements, issue cease and desist orders, terminate deposit insurance, impose substantial fines 
and  other  civil  penalties  and  appoint  a  conservator  or  receiver.  Failure  to  comply  with  applicable  laws  or  regulations  could 
subject Comerica or its banking subsidiaries, as well as officers and directors of these organizations, to administrative sanctions 
and  potentially  substantial  civil  and  criminal  penalties.  Bank  regulators  regularly  examine  the  operations  of  bank  holding 
companies  and  banks,  and  the  results  of  these  examinations,  as  well  as  certain  supervisory  and  enforcement  actions,  are 
confidential and may not be made public. Regulatory and supervisory scrutiny of regional banking organizations has recently 
increased as a result of the bank failures in the spring of 2023.

Resolution Plans

As a depository institution with $50 billion or more of total consolidated assets, the Bank is required to periodically 
file  a  resolution  plan  with  the  FDIC.  On  April  16,  2019,  the  FDIC  released  an  advanced  notice  of  proposed  rulemaking 
(“ANPR”) with respect to the FDIC’s bank resolution plan requirements meant to better tailor bank resolution plans to a firm’s 
size, complexity and risk profile. In connection with this rulemaking, the FDIC placed a moratorium on resolution plans until 
the rulemaking process was complete.

On June 25, 2021, the FDIC lifted the moratorium on resolution plan submissions for institutions with $100 billion or 
more  in  total  assets.  Under  the  FDIC’s  Statement  on  Resolution  Plans  for  IDIs,  an  institution  will  be  required  to  submit 
resolution plans when it has $100 billion or more in total assets as determined based upon the average of the institution’s four 
most recent Reports of Condition and Income. 

On August 29, 2023, the FDIC released a proposed rule that would require insured depository institutions with assets 
of at least $50 billion but less than $100 billion, such as the Bank, to submit resolution-related informational filings. Comerica 
is monitoring the development of this proposal.

Incentive-Based Compensation

Comerica is subject to guidance issued by the FRB, OCC and FDIC intended to ensure that the incentive compensation 
policies of banking organizations do not undermine the safety and soundness of such organizations by encouraging excessive 
risk-taking. The guidance, which covers senior executives as well as other employees who, either individually or as part of a 
group, have the ability to expose the banking organization to material amounts of risk, is based upon the key principles that a 
banking organization's incentive compensation arrangements (i) should provide employees incentives that appropriately balance 
risk and financial results in a manner that does not encourage employees to expose their organizations to imprudent risk; (ii) 
should  be  compatible  with  effective  controls  and  risk-management;  and  (iii)  should  be  supported  by  strong  corporate 
governance,  including  active  and  effective  oversight  by  the  organization's  board  of  directors.  Banking  organizations  are 
expected  to  review  regularly  their  incentive  compensation  arrangements  based  on  these  three  principles.  Where  there  are 
deficiencies  in  the  incentive  compensation  arrangements,  they  should  be  promptly  addressed.  Enforcement  actions  may  be 
taken  against  a  banking  organization  if  its  incentive  compensation  arrangements,  or  related  risk-management  control  or 
governance  processes,  pose  a  risk  to  the  organization's  safety  and  soundness,  particularly  if  the  organization  is  not  taking 
prompt  and  effective  measures  to  correct  the  deficiencies.  Similar  to  other  large  banking  organizations,  Comerica  has  been 
subject  to  a  continuing  review  of  incentive  compensation  policies  and  practices  by  representatives  of  the  FRB,  the  Federal 
Reserve Bank of Dallas and the Texas Department of Banking since 2011. As part of that review, Comerica has undertaken a 
thorough analysis of all the incentive compensation programs throughout the organization, the individuals covered by each plan 
and  the  risks  inherent  in  each  plan’s  design  and  implementation.  Comerica  has  determined  that  risks  arising  from  employee 
compensation plans are not reasonably likely to have a material adverse effect on Comerica. It is Comerica’s intent to continue 
monitoring regulations and best practices for sound incentive compensation practices.

In  2016,  the  FRB,  OCC  and  several  other  federal  financial  regulators  revised  and  re-proposed  rules  to  implement 
Section 956 of the Dodd-Frank Act. Section 956  directed  regulators  to jointly  prescribe regulations  or  guidelines prohibiting 
incentive-based payment arrangements, or any feature of any such arrangement, at covered financial institutions that encourage 
inappropriate  risks  by  providing  excessive  compensation  or  that  could  lead  to  a  material  financial  loss.  This  proposal  would 
supplement the final guidance issued by the banking agencies in June 2010. Consistent with the Dodd-Frank Act, the proposed 
rule would impose heightened standards for institutions with $50 billion or more in total consolidated assets, which includes 
Comerica. For these larger institutions, the proposed rule would require the deferral of at least 40 percent of incentive-based 
payments  for  designated  executives  and  significant  risk-takers  who  individually  have  the  ability  to  expose  the  institution  to 
possible losses that are substantial in relation to the institution's size, capital or overall risk tolerance. Moreover, incentive-based 
compensation of these individuals would be subject to potential clawback for seven years following vesting. Further, the rule 
would impose enhanced risk management controls and governance and internal policy and procedure requirements with respect 
to incentive compensation. Comerica is monitoring the development of this proposal.

The Volcker Rule

Comerica is prohibited under the Volcker Rule from (1) engaging in short-term proprietary trading for its own account 
and (2) having certain ownership interests in and relationships with hedge funds or private equity funds ("Covered Funds"). The 
Volcker  Rule  regulations  contain  exemptions  for  market-making,  hedging,  underwriting  and  trading  in  U.S.  government  and 
agency obligations, and permit certain ownership interests in certain types of Covered Funds to be retained. They also permit 
the  offering  and  sponsoring  of  Covered  Funds  under  certain  conditions.  The  Volcker  Rule  regulations  impose  significant 
compliance and reporting obligations on banking entities. 

Comerica has compliance programs required by the Volcker Rule and has either divested or received extensions for 

any holdings in Covered Funds.   

10

 
In  October  2019,  the  five  federal  agencies  with  rulemaking  authority  with  respect  to  the  Volcker  Rule  finalized 
changes  designed  to  simplify  compliance  with  the  Volcker  Rule.  The  final  rule  formalized  a  three-tiered  approach  to 
compliance  program  requirements  for  banking  entities  based  on  their  level  of  trading  activity.  As  a  banking  entity  with 
“moderate” trading assets and liabilities (less than $20 billion), Comerica is subject to simplified compliance requirements. In 
June  2020,  regulators  finalized  a  rule  further  modifying  the  Volcker  Rule’s  prohibition  on  banking  entities  investing  in  or 
sponsoring Covered Funds. The final rule modifies three areas of the rule by: streamlining the covered funds portion of the rule; 
addressing the extraterritorial treatment of certain foreign funds; and permitting banking entities to offer financial services and 
engage  in  other  activities  that  do  not  raise  concerns  that  the  Volcker  Rule  was  intended  to  address.  Comerica  continues  to 
follow Volcker Rule developments.

Derivative Transactions

As a state member bank, the Bank may engage in derivative transactions, as permitted by applicable Texas and federal 
law.  Title  VII  of  the  Dodd-Frank  Act  contains  a  comprehensive  framework  for  over-the-counter  (“OTC”)  derivatives 
transactions.  Even  though  many  of  the  requirements  do  not  impact  Comerica  directly,  since  the  Bank  does  not  meet  the 
definition  of  swap  dealer  or  major  swap  participant,  Comerica  continues  to  review  and  evaluate  the  extent  to  which  such 
requirements  impact  its  business  indirectly.  On  November  5,  2018,  the  CFTC  issued  a  final  rule  that  sets  the  permanent 
aggregate gross notional amount threshold for the de minimis exception from the definition of swap dealer at $8 billion in swap 
dealing activity entered into by a person over the preceding 12 months. Comerica's swap dealing activities for purposes of the 
de minimis exception are currently below this threshold.

The  initial  margin  requirements  for  non-centrally  cleared  swaps  and  security-based  swaps  were  effective  for 
Comerica’s  swap  and  security-based  swap  counterparties  that  are  swap  dealers  or  major  swap  participants  on  September  1, 
2022, and such counterparties are required to collect initial margin from Comerica. The initial margin requirements were issued 
for the purpose of ensuring safety and soundness of swap trading in light of the risk to the financial system associated with non-
cleared swaps activity. 

Consumer Financial Protection Bureau and Certain Recent Consumer Finance Regulations

Comerica is subject to regulation by the CFPB, which has broad rule-making authority for a wide range of consumer 
protection laws that apply to all banks and savings institutions and possesses examination and enforcement authority over all 
banks and savings institutions with more than $10 billion in assets, including the Bank, and their depository affiliates. Among 
other  things,  the  CFPB  is  focused  on  reducing  or  eliminating  so-called  "junk  fees"  which  include  some  sources  of  bank  fee 
revenue.

Comerica  is  also  subject  to  certain  state  consumer  protection  laws,  and  under  the  Dodd-Frank  Act,  state  attorneys 
general and other state officials are empowered to enforce certain federal consumer protection laws and regulations. In recent 
years,  state  authorities  have  increased  their  focus  on  and  enforcement  of  consumer  protection  rules.  These  federal  and  state 
consumer protection laws apply to a broad range of Comerica’s activities and to various aspects of its business and include laws 
relating to interest rates, fair lending, disclosures of credit terms and estimated transaction costs to consumer borrowers, debt 
collection practices, the use of and the provision of information to consumer reporting agencies, and the prohibition of unfair, 
deceptive  or  abusive  acts  or  practices  in  connection  with  the  offer,  sale  or  provision  of  consumer  financial  products  and 
services.

UNDERWRITING APPROACH

The loan portfolio is a primary source of profitability and risk, so proper loan underwriting is critical to Comerica's 
long-term  financial  success.  Comerica  extends  credit  to  businesses,  individuals  and  public  entities  based  on  sound  lending 
principles  and  consistent  with  prudent  banking  practice.  During  the  loan  underwriting  process,  a  qualitative  and  quantitative 
analysis of potential credit facilities is performed, and the credit risks associated with each relationship are evaluated. Important 
factors considered as part of the underwriting process for new loans and loan renewals include:

•

•

•

•

•

People: Including the competence, integrity and succession planning of customers.

Purpose: The legal, logical and productive purposes of the credit facility.

Payment: Including the source, timing and probability of payment.

Protection:  Including  obtaining  alternative  sources  of  repayment,  securing  the  loan,  as  appropriate,  with 
collateral and/or third-party guarantees and ensuring appropriate legal documentation is obtained.

Perspective: The risk/reward relationship and pricing elements (cost of funds; servicing costs; time value of 
money; credit risk).

Comerica  prices  credit  facilities  to  reflect  risk,  the  related  costs  and  the  expected  return,  while  maintaining 
competitiveness with other financial institutions. Loans with variable and fixed rates are underwritten to achieve expected risk-

11

adjusted returns on the credit facilities and for the full relationship including the borrower's ability to repay the principal and 
interest based on such rates.

Credit Approval and Monitoring 

Approval of new loan exposure and oversight and monitoring of Comerica's loan portfolio is the joint responsibility of 
the Credit Risk Management and Decisioning department and the Credit Underwriting department (collectively referred to as 
“Credit”), plus the business units (“Line”). Credit assists the Line with underwriting by providing objective financial analysis, 
including an assessment of the borrower's business model, balance sheet, cash flow and collateral. The approval of new loan 
exposure  is  the  joint  responsibility  of  Credit  Risk  Management  and  Decisioning  and  the  Line.  Each  commercial  borrower 
relationship  is  assigned  an  internal  risk  rating  by  Credit  Risk  Management  and  Decisioning.  Further,  Credit  updates  the 
assigned internal risk rating as new information becomes available as a result of periodic reviews of credit quality, a change in 
borrower  performance  or  approval  of  new  loan  exposure.  The  goal  of  the  internal  risk  rating  framework  is  to  support 
Comerica's  risk  management  capability,  including  its  ability  to  identify  and  manage  changes  in  the  credit  risk  profile  of  its 
portfolio,  predict  future  losses  and  price  the  loans  appropriately  for  risk.  Finally,  the  Line  and  Credit  (including  its  Credit 
Analytics and Strategy department) work together to insure the overall credit risk within the loan portfolio is consistent with the 
Bank’s Credit Risk Appetite.

Credit Policy

Comerica  maintains  a  comprehensive  set  of  credit  policies.  Comerica's  credit  policies  provide  Line  and  Credit 
Personnel with a framework of sound underwriting practices and potential loan structures. These credit policies also provide the 
framework  for  loan  committee  approval  authorities  based  on  its  internal  risk-rating  system  and  establish  maximum  exposure 
limits based on risk ratings and Comerica's legal lending limit. Credit, in conjunction with the Line, monitors compliance with 
the credit policies and modifies the existing policies as necessary. New or modified policies/guidelines require approval by the 
Strategic  Credit  Committee,  chaired  by  Comerica's  Chief  Credit  Officer  and  comprised  of  senior  credit,  market  and  risk 
management executives.

Commercial Loan Portfolio

Commercial  loans  are  underwritten  using  a  comprehensive  analysis  of  the  borrower's  operations.  The  underwriting 

process includes an analysis of some or all of the factors listed below:

•

•

•

•

•

•

•

•

The borrower's business model and industry characteristics.

Periodic  review  of  financial  statements  including  financial  statements  audited  by  an  independent  certified 
public accountant when appropriate.

The proforma financial condition including financial projections.

The borrower's sources and uses of funds.

The borrower's debt service capacity.

The guarantor's financial strength.

A comprehensive review of the quality and value of collateral, including independent third-party appraisals of 
machinery and equipment and commercial real estate, as appropriate, to determine the advance rates.

Physical inspection of collateral and audits of receivables, as appropriate.

For  additional  information  specific  to  certain  businesses  within  our  commercial  portfolio,  please  see  the  caption 

“Concentrations of Credit Risk" in the Financial Section of this report.

Commercial Real Estate (CRE) Loan Portfolio

Comerica's CRE loan portfolio consists of real estate construction and commercial mortgage loans and includes loans 
to  real  estate  developers  and  investors  and  loans  secured  by  owner-occupied  real  estate.  Comerica's  CRE  loan  underwriting 
policies are consistent with the approach described above and provide maximum loan-to-value ratios that limit the size of a loan 
to a maximum percentage of the value of the real estate collateral securing the loan. The loan-to-value percentage varies by the 
type  of  collateral  and  is  limited  by  advance  rates  established  by  our  regulators.  Our  loan-to-value  limitations  are,  in  certain 
cases, more restrictive than those required by regulators and are influenced by other risk factors such as the financial strength of 
the borrower or guarantor, the equity provided to the project and the viability of the project itself. CRE loans generally require 
cash equity. CRE loans are normally originated with full recourse or limited recourse to all principals and owners. There are 
limitations  to  the  size  of  a  single  project  loan  and  to  the  aggregate  dollar  exposure  to  a  single  guarantor.  For  additional 
information  specific  to  our  CRE  loan  portfolio,  please  see  the  caption  “Commercial  Real  Estate  Lending”  in  the  Financial 
Section of this report.

Consumer and Residential Mortgage Loan Portfolios

Comerica's consumer and residential mortgage loan underwriting includes an assessment of each borrower's personal 
financial  condition,  including  a  review  of  credit  reports  and  related  FICO  scores  (a  type  of  credit  score  used  to  assess  an 
applicant's credit risk) and verification of income and assets, as applicable. After origination, internal risk ratings are assigned 
based on payment status and product type.

Comerica  does  not  originate  subprime  loans.  Although  a  standard  industry  definition  for  subprime  loans  (including 
subprime  mortgage  loans)  does  not  exist,  Comerica  defines  subprime  loans  as  specific  product  offerings  for  higher  risk 
borrowers, including individuals with one or a combination of high credit risk factors. These credit factors include low FICO 
scores, poor patterns of payment history, high debt-to-income ratios and elevated loan-to-value. Comerica generally considers 
subprime FICO scores to be those below 620 on a secured basis (excluding loans with cash or near-cash collateral and adequate 
income to make payments) and below 660 for unsecured loans. Residential mortgage loans retained in the portfolio are largely 
relationship  based.  The  remaining  loans  are  typically  eligible  to  be  sold  on  the  secondary  market.  Adjustable-rate  loans  are 
limited to standard conventional loan programs. For additional information specific to our residential real estate loan portfolio, 
please see the caption “Residential Real Estate Lending” in the Financial Section of this report.

HUMAN CAPITAL RESOURCES

Comerica’s  relationship  banking  strategy  relies  heavily  on  the  personal  relationships  and  the  quality  of  service 
provided  by  employees.  Accordingly,  Comerica  aims  to  attract,  develop  and  retain  employees  who  can  drive  financial  and 
strategic growth objectives and build long-term shareholder value. Key items related to Comerica’s human capital resources are 
described below.

Structure.   As of December 31, 2023, Comerica and its subsidiaries had 7,496 full-time and 367 part-time employees, 
primarily  located  in  Comerica’s  primary  markets  of  Michigan,  Texas,  California,  Arizona,  Florida  and  North  Carolina. 
Comerica’s Chief Administrative Officer and Chief Human Resources Officer reports directly to the Chairman, President and 
CEO  and  manages  all  aspects  of  the  employee  experience,  including  talent  acquisition,  diversity  and  inclusion,  learning  and 
development, talent management, compensation and benefits. 

The  Governance,  Compensation  and  Nominating  Committee  of  the  Board  reviews  Comerica’s  human  capital 
management  strategy  and  talent  development  program,  including  recruitment,  evaluations  and  development  activities.  This 
Committee  also  reviews  Comerica’s  employee  diversity,  equity  and  inclusion  initiatives,  as  well  as  the  results  of  those 
initiatives. The full Board, either directly or through one or more of its committees, is provided annual workforce updates. To 
enhance the Board’s understanding of Comerica's talent pipeline, the Board routinely meets with high-potential employees in 
formal and informal settings.

Productivity.    Comerica  carefully  manages  the  size  of  its  workforce  and  reallocates  resources  as  needed.  As  of 
December  31,  2023,  Comerica’s  total  employee  headcount,  on  a  full-time  equivalent  basis,  was  13  percent  lower  than  as  of 
December 31, 2015. Additionally, for 2023, Comerica managed an average of $16 million of loans and deposits per employee. 

Diversity  Comerica has an organization-wide focus on an inclusive workforce that resembles the communities that it 

serves. As of December 31, 2023, Comerica’s U.S. colleagues had the following attributes:

Employees
Officials and Managers(1)
Executive Officers(2)

Forbes recognized Comerica as "One of Dallas-Fort Worth's Top Workplaces." Newsweek listed Comerica in its 2024 
list  of  America’s  Greatest  Workplaces  for  Diversity.  The  Hispanic  Association  on  Corporate  Responsibility  rated  Comerica 
with  five  stars  –  the  highest  marking  –  in  the  category  of  governance  in  its  2023  Corporate  Inclusion  Index.  Human  Rights 
Campaign's Corporate Equality Index (for LGBTQ+ equality) once again gave Comerica a perfect score of 100% in 2023. 

Comerica has thirteen Employee Resource Groups (ERGs), consisting of employees with common interests organized 
to  promote  professional  development,  social  networking,  awareness  and  inclusion,  social  impact  and  talent  attraction  and 
retention. The ERGs help support and sustain Comerica's diversity and inclusion model. These groups include All Abilities and 
Allies;  Comerica  African  American  Network;  Comerica  Asian  and  Pacific  Islander  Network;  Comerica  Asian  Indian 
Association; Comerica Young Professionals Network; Comerica Quantitative Professionals Network; Jewish Heritage; PRISM 
–  LGBTQ+;  Mi  Gente;  The  European  Connection;  Veteran’s  Leadership  Network;  Women’s  Forum;  and  Women  in 
Technology.

13

Compensation and Benefits.  Comerica strives to provide pay, benefits and programs that help meet the varying needs 
of  its  employees.  Compensation  and  benefits  include  market-competitive  pay,  retirement  programs,  broad-based  bonuses,  an 
employee stock purchase plan, health and welfare benefits, an employee assistance program, financial counseling, paid time off, 
family leave and flexible work schedules. In 2023, Comerica kept its minimum wage at $18 per hour. Additionally, for 2023, 
Comerica  held  the  proportion  that  employees  pay  for  their  medical  and  dental  benefits  steady,  absorbing  proportional  cost 
increases. Comerica periodically examines the main components of compensation, like salaries and bonuses, by grade level and 
position  to  ensure  similar  positions  receive  similar  pay  to  the  extent  other  factors  can  be  equalized  (e.g.,  time  in  position, 
performance, education). Comerica also considers equitable benefits and looks at policies and practices that potentially drive 
inequities. Solicitation of salary history from applicants is prohibited.

Attraction, Development and Retention.  Comerica measures the success of its talent acquisition strategy on speed and 
quality of acquisition, diversity of its applicant pool, and new colleague retention. In addition, overall performance metrics are 
tracked  for  each  key  business  line.  Sourcing  strategies  and  support  structures  are  evaluated  and  modified  to  ensure  that 
performance targets are met consistently.

Comerica operates and continues to evolve multiple internal programs to support the development and retention of its 
colleagues,  including  Comerica  University,  internal  Leadership  Development,  Emerging  Leaders,  and  Senior  Leadership 
programs  designed  to  develop  high  potential  employees,  a  Future-Ready  Technology  skills  program  to  help  re-  and  up-skill 
Technology colleagues, a Managing Essentials Certificate series for managers and organizational change management learning 
for all colleagues. In 2023, over 14,000 skills-based titles were offered to Comerica colleagues and an average of around 24 
hours of training per employee were completed. Comerica also supports its employees’ involvement in external development 
programs and volunteerism. All full-time colleagues are granted up to 8 hours of PTO annually, and all part-time colleagues are 
granted up to 4 hours of PTO annually to use for volunteer events. This includes volunteer opportunities related and unrelated 
to Comerica.

Comerica’s investment in its employees has resulted in a long-tenured workforce, with average tenure of around 12 
years of service. Of the approximately 2,330 open employee positions filled in 2023, 61% were filled by external hires and 39% 
positions were filled by internal hires. Employee turnover for 2023 was approximately 15%. In 2023, Comerica conducted its 
third enterprise-wide employee engagement survey, with approximately 85% of colleagues participating.

which change over time. Forward-looking statements speak only as of the date the statement is made, and Comerica does not 
undertake to update forward-looking statements to reflect facts, circumstances, assumptions or events that occur after the date 
the  forward-looking  statements  are  made.  Actual  results  could  differ  materially  from  those  anticipated  in  forward-looking 
statements and future results could differ materially from historical performance.

In addition to factors mentioned elsewhere in this report or previously disclosed in Comerica's SEC reports (accessible 
on  the  SEC's  website  at  www.sec.gov  or  on  Comerica's  website  at  www.comerica.com),  the  factors  contained  below,  among 
others, could cause actual results to differ materially from forward-looking statements, and future results could differ materially 
from historical performance.

CREDIT RISK

•

Changes  in  customer  behavior  due  to  outside  factors  may  adversely  impact  Comerica's  business,  financial 
condition and results of operations.

As a financial institution, the Corporation's principal activity is lending to and accepting deposits from businesses and 
individuals.  The  primary  source  of  revenue  is  net  interest  income,  which  is  principally  derived  from  the  difference 
between interest earned on loans and investment securities and interest paid on deposits and other funding sources. The 
Corporation  also  provides  other  products  and  services  that  meet  the  financial  needs  of  customers  which  generate 
noninterest income, the Corporation's secondary source of revenue. Growth in loans, deposits and noninterest income 
is  affected  by  many  factors,  including  economic  conditions  in  the  markets  the  Corporation  serves,  the  financial 
requirements and economic health of customers and the ability to add new customers and/or increase the number of 
products  used  by  current  customers.  Success  in  providing  products  and  services  depends  on  the  financial  needs  of 
customers and the types of products desired.

Individual,  economic,  political,  industry-specific  conditions  and  other  factors  outside  of  Comerica's  control,  such  as 
pandemics, inflation, military conflicts, labor shortages, supply chain constraints, fuel prices, energy costs, tariffs, real 
estate values or other factors that affect customer income levels, could alter predicted customer borrowing, repayment, 
investment and deposit practices. Such a change in these practices could materially adversely affect Comerica's ability 
to anticipate business needs and meet regulatory requirements.

Further,  difficult  economic  conditions,  such  as  a  recession,  may  negatively  affect  consumer  confidence  levels.  A 
decrease in consumer confidence levels would likely aggravate the adverse effects of these difficult market conditions 
on Comerica, Comerica's customers and others in the financial institutions industry.

Unfavorable developments concerning credit quality could adversely affect Comerica's financial results.

Although Comerica regularly reviews credit exposure related to its customers and various industry sectors in which it 
has business relationships, default risk may arise from events or circumstances that are difficult to detect or foresee. 
Under  such  circumstances,  as  occurred  during  and  as  a  result  of  the  COVID-19  pandemic  and  may  reoccur  due  to 
other pandemics or crises, Comerica could experience an increase in the level of provision for credit losses and reserve 
for  credit  losses,  which  could  adversely  affect  Comerica's  financial  results.  Additionally,  some  of  Comerica's  loan 
portfolios  have  higher  risk  profiles  relative  to  the  rest  of  our  portfolio,  such  as  Technology  and  Life  Sciences, 
automotive production and the leveraged transactions book. These loan portfolios have higher levels of criticized loans 
than  the  general  population,  and  further  migration  could  lead  to  an  adverse  effect  on  credit  metrics  and  Comerica's 
financial results. For more information, please see "Leveraged Loans” and "Automotive Lending - Production" in of 
the Financial Section of this report. 

•

Declines  in  the  businesses  or  industries  of  Comerica's  customers  could  cause  increased  credit  losses  or 
decreased loan balances, which could adversely affect Comerica.

Comerica's  business  customer  base  consists,  in  part,  of  customers  in  volatile  businesses  and  industries  such  as  the 
automotive,  commercial  real  estate,  residential  real  estate  and  energy  industries.  These  industries  are  sensitive  to 
global  economic  conditions,  supply  chain  factors  and/or  commodities  prices.  Additionally,  certain  segments  of  the 
commercial  real  estate  industry  have  been  under  pressure  due  to  rapidly  rising  interest  rates,  shifts  in  demand  (i.e., 
office, retail), labor and materials shortages and capital markets volatility. Finally, energy prices continue to fluctuate 
and energy companies are expected to experience environmental pressure over the long-term. Any decline in one of 
these  businesses  or  industries  could  cause  increased  credit  losses  or  reduced  loan  demand,  which  in  turn  could 
adversely affect Comerica. As a regional banking organization, our credit risks (and many other of our risks) may be 
exacerbated by events or factors that disproportionately affect the markets in which we operate, accept deposits, make 
loans or invest. For more information regarding certain of Comerica's lines of business, please see "Concentrations of 

15

Credit  Risk,"  "Commercial  Real  Estate  Lending,"  "Automotive  Lending  -  Dealer,"  "Automotive  Lending  - 
Production," "Residential Real Estate Lending," and “Energy Lending” in the Financial Section of this report. 

MARKET RISK

•

•

Governmental monetary and fiscal policies may adversely affect the financial services industry, and therefore 
impact Comerica's financial condition and results of operations.

Monetary  and  fiscal  policies  of  various  governmental  and  regulatory  agencies,  in  particular  the  FRB,  affect  the 
financial services industry, directly and indirectly. The FRB regulates the supply of money and credit in the U.S., and 
its monetary policies determine in large part Comerica's cost of funds for lending and investing and the return that can 
be earned on such loans and investments. Changes in such policies, including changes in interest rates or changes in 
the FRB's balance sheet, influence the origination of loans, the value of investments, the generation of deposits and the 
rates  received  on  loans  and  investment  securities  and  paid  on  deposits.  Changes  in  monetary  and  fiscal  policies  are 
beyond Comerica's control and difficult to predict. Comerica's financial condition and results of operations could be 
materially adversely impacted by changes in governmental monetary and fiscal policies.

Fluctuations in interest rates and their impact on deposit pricing could adversely affect Comerica's net interest 
income and balance sheet.

The operations of financial institutions such as Comerica are dependent to a large degree on net interest income, which 
is the difference between interest income from loans and investments and interest expense on deposits and borrowings. 
Prevailing  economic  conditions  and  the  trade,  fiscal  and  monetary  policies  of  the  federal  government  and  various 
regulatory agencies all affect market rates of interest and the availability and cost of credit, which in turn significantly 
affect financial institutions' net interest income and the market value of its investment securities. The Federal Reserve 
raised interest rates four times in 2023; if the Federal Reserve lowers interest rates in the future, it will adversely affect 
the interest income Comerica earns on loans and investments. Further, while Comerica has taken steps to reduce its 
interest  rate  sensitivity,  those  actions,  such  as  the  execution  of  Comerica's  hedging  strategy,  do  not  fully  eliminate 
interest rate  risk. For a  discussion of Comerica's interest  rate  sensitivity  and  risk management  strategies,  please see, 
“Market and Liquidity Risk” in the Financial Section of this report.

Deposits make up a large portion of Comerica’s funding portfolio. Comerica's funding costs may increase if it raises 
deposit rates to avoid losing customer deposits, as we did in 2023, or if it loses customer deposits and must rely on 
more expensive sources of funding. 

Volatility  in  interest  rates  can  also  result  in  disintermediation,  which  is  the  flow  of  funds  away  from  financial 
institutions into direct investments, such as federal government and corporate securities and other investment vehicles, 
which generally pay higher rates of return than financial institutions. Comerica's financial results could be materially 
adversely impacted by changes in financial market conditions.

•

Comerica's  transition  away  from  the  Bloomberg  Short-Term  Bank  Yield  Index,  or  "BSBY,"  could  adversely 
affect its financial results.

On  November  15,  2023,  Bloomberg  Index  Services  Limited  announced  it  will  discontinue  publishing  BSBY  on 
November 15, 2024. Comerica is transitioning a number of arrangements to other rates, primarily Secured Overnight 
Financing Rate (“SOFR”). 

As a result of this transition, interest rates on our floating rate loans, derivatives, and other financial instruments tied to 
BSBY  rates,  as  well  as  the  revenue  and  expenses  associated  with  those  financial  instruments,  may  be  adversely 
affected. As Comerica works through the complicated product transitions involved, Comerica’s relationships with its 
customers  may  suffer.  Comerica  may  need  to  make  additional  efforts  to  retain  customers,  avoid  disruptions  to 
customer service and ensure the products continue to fulfill their intended purposes for customers. Comerica may also 
be  harmed  by  operational  errors,  inconsistencies  or  inefficiencies  inherent  in  making  these  transitions.  Further, 
Comerica’s  transition  could  prompt  inquiries  or  other  actions  from  regulators.  It  could  also  result  in  disputes  with 
counterparties regarding the terms of the arrangements Comerica seeks to change.  

LIQUIDITY RISK

•

Comerica must maintain adequate sources of funding and liquidity to meet regulatory expectations, support its 
operations and fund outstanding liabilities.

Comerica’s  liquidity  and  ability  to  fund  and  run  its  business  could  be  materially  adversely  affected  by  a  variety  of 
conditions and factors, including financial and credit market disruptions and volatility, a lack of market or customer 
confidence in financial markets in general, or deposit competition based on interest rates, which may result in a loss of 

16

customer deposits or outflows of cash or collateral and/or adversely affect Comerica's ability to access capital markets 
on favorable terms. 

Other conditions and factors that could materially adversely affect Comerica’s liquidity and funding include a lack of 
market or customer confidence in, or negative news about, Comerica or the financial services industry generally which 
also may result in a loss of deposits and/or negatively affect Comerica's ability to access the capital markets; the loss of 
customer  deposits  to  alternative  investments;  counterparty  availability;  interest  rate  fluctuations;  general  economic 
conditions;  and  the  legal,  regulatory,  accounting  and  tax  environments  governing  Comerica's  funding  transactions. 
Many of the above conditions and factors may be caused by events over which Comerica has little or no control. There 
can be no assurance that significant disruption and volatility in the financial markets will not occur in the future. As 
occurred following the collapse of certain banks early in 2023, the failure of other financial institutions could cause 
deposit  outflows  if  customers  were  to  spread  deposits  among  several  different  banks  to  maximize  their  FDIC 
insurance, move deposits to banks deemed "too big to fail," or remove deposits from the U.S. financial system entirely. 
Comerica has a high percentage of uninsured deposits and relies on its deposit base for liquidity. Further, Comerica's 
customers may be adversely impacted by such conditions, which could have a negative impact on Comerica's business, 
financial condition and results of operations.  

Additionally,  if  Comerica  is  for  these  or  any  other  reason  unable  to  continue  to  fund  assets  through  customer  bank 
deposits  or  access  funding  sources  on  favorable  terms,  or  if  Comerica  suffers  an  increase  in  borrowing  costs  or 
otherwise fails to manage liquidity effectively, Comerica’s liquidity, operating margins, financial condition and results 
of operations may be materially adversely affected. 

Management is not currently engaged in repurchasing shares and will continue to monitor various factors, including 
the  Corporation's  earnings  generation,  capital  needs  to  fund  future  loan  growth,  regulatory  changes  and  market 
conditions, before resuming the share repurchase program. At all times, Comerica may be unable to generate sufficient 
returns to repurchase shares, or may choose to devote capital to other uses rather than repurchase shares.

•

Reduction in our credit ratings could adversely affect Comerica and/or the holders of its securities.

Rating agencies regularly evaluate Comerica, and their ratings are based on a number of factors, including Comerica's 
financial strength as well as factors not entirely within its control, such as conditions affecting the financial services 
industry generally. Following banking industry disruptions in early 2023, Moody's downgraded the Corporation and 
Bank's  credit  ratings  and  changed  the  Corporation  and  Bank's  outlooks  to  Negative  related  to  uncertainty  in  the 
banking  industry;  Moody's  also  lowered  the  macro  profile  of  the  U.S.  banking  system,  reflecting  general  concern 
around  the  banking  industry  as  a  whole.  Similarly  following  those  disruptions,  Standard  &  Poor's  downgraded  the 
Corporation and Bank's credit ratings while reaffirming their outlooks at Stable, and Fitch changed the Corporation's 
and the Bank's outlooks to Negative, noting relatively higher usage of brokered deposits and wholesale funding. There 
can be no assurance that Comerica will maintain its current ratings. While recent credit rating actions have had little to 
no  detrimental  impact  on  Comerica's  profitability,  borrowing  costs,  or  ability  to  access  the  capital  markets,  future 
downgrades to Comerica's or its subsidiaries' credit ratings could adversely affect Comerica's profitability, borrowing 
costs, or ability to access the capital markets or otherwise have a negative effect on Comerica's results of operations or 
financial condition. If such a reduction placed Comerica's or its subsidiaries' credit ratings below investment grade, it 
could  also  create  obligations  or  liabilities  under  the  terms  of  existing  arrangements  that  could  increase  Comerica's 
costs  under  such  arrangements.  Additionally,  a  downgrade  of  the  credit  rating  of  any  particular  security  issued  by 
Comerica or its subsidiaries could negatively affect the ability of the holders of that security to sell the securities and 
the prices at which any such securities may be sold.

•

The soundness of other financial institutions could adversely affect Comerica.

Comerica's ability to engage in routine funding transactions could be adversely affected by the actions and commercial 
soundness of other financial institutions. Financial services institutions are interrelated as a result of trading, clearing, 
counterparty  or  other  relationships.  Comerica  has  exposure  to  many  different  industries  and  counterparties,  and  it 
routinely executes transactions with counterparties in the financial industry, including brokers and dealers, commercial 
banks,  investment  banks,  mutual  and  hedge  funds,  and  other  institutional  clients.  As  a  result,  defaults  by,  or  even 
rumors or questions about, one or more financial services institutions, or the financial services industry generally, have 
led,  and  may  further  lead,  to  market-wide  liquidity  problems  and  could  lead  to  losses  or  defaults  by  us  or  by  other 
institutions. Many of these transactions could expose Comerica to credit risk in the event of default of its counterparty 
or client. In addition, Comerica's credit risk may be impacted when the collateral held by it cannot be monetized or is 
liquidated  at  prices  not  sufficient  to  recover  the  full  amount  of  the  financial  instrument  exposure  due  to  Comerica. 
Further, volatility in the banking industry may lead to greater reliance on third parties that provide money market or 
deposit sweep services. In addition, many of these transactions could expose Comerica to credit risk in the event of 

17

default of its counterparty  or client. There is no  assurance  that any  such  losses  would  not  adversely  affect, possibly 
materially, Comerica.

TECHNOLOGY RISK

•

Comerica faces security risks, including denial of service attacks, hacking, social engineering attacks targeting 
Comerica’s  colleagues  and  customers,  malware  intrusion  or  data  corruption  attempts,  and  identity  theft  that 
could result in the disclosure of confidential information, adversely affect its business or reputation, and create 
significant legal and financial exposure.

Comerica’s  computer  systems  and  network  infrastructure  and  those  of  third  parties,  on  which  Comerica  is  highly 
dependent,  are  subject  to  security  risks  and  could  be  susceptible  to  cyber  attacks,  such  as  denial  of  service  attacks, 
hacking, terrorist activities or identity theft. Comerica’s business relies on the secure processing, transmission, storage 
and  retrieval  of  confidential,  proprietary  and  other  information  in  its  computer  and  data  management  systems  and 
networks,  and  in  the  computer  and  data  management  systems  and  networks  of  third  parties.  In  addition,  to  access 
Comerica’s network, products and services, its customers and other third parties may use personal mobile devices or 
computing devices that are outside of its network environment and are subject to their own cybersecurity risks.

Cyber  attacks  could  include  computer  viruses,  malicious  or  destructive  code,  phishing  attacks,  denial  of  service  or 
information, ransomware, improper access by employees or vendors, attacks on personal email of employees, ransom 
demands to not expose security vulnerabilities in Comerica's systems or the systems of third parties, or other security 
breaches, and could result in the destruction or exfiltration of data and systems. As cyber threats continue to evolve, 
Comerica may be required to expend significant additional resources to continue to modify or enhance its protective 
measures or to investigate and remediate any information security vulnerabilities or incidents. Despite efforts to ensure 
the  integrity  of  Comerica’s  systems  and  implement  controls,  processes,  policies  and  other  protective  measures, 
Comerica may not be able to anticipate all security breaches. Nor may it (or the third parties whose systems we rely 
upon) be able to implement guaranteed preventive measures against such security breaches. Cyber threats are rapidly 
evolving  and  Comerica  may  not  be  able  to  anticipate  or  prevent  all  such  attacks  and  could  be  held  liable  for  any 
security breach or loss.

Although Comerica has programs in place related to business continuity, disaster recovery and information security to 
maintain the confidentiality, integrity, and availability of its systems, business applications and customer information, 
such disruptions may still give rise to interruptions in service to customers and loss or liability to Comerica, including 
loss  of  customer  data.  Like  other  financial  services  firms,  Comerica  and  its  third  party  providers  continue  to  be  the 
subject  of  cyber  attacks.  Although  to  this  date  Comerica  has  not  experienced  any  material  losses  or  other  material 
consequences related to cyber attacks, future cyber attacks could be more disruptive and damaging, and Comerica may 
not be able to anticipate or prevent all such attacks. Further, cyber attacks may not be detected in a timely manner.

Cyber attacks or other information or security breaches, whether directed at Comerica or third parties, may result in a 
material  loss  or  have  material  consequences.  Furthermore,  the  public  perception  that  a  cyber  attack  on  Comerica’s 
systems has been successful, whether or not this perception is correct, may damage its reputation with customers and 
third parties with whom it does business. Hacking of personal information and identity theft risks, in particular, could 
cause serious reputational harm. A successful penetration or circumvention of system security could cause Comerica 
serious  negative  consequences,  including  loss  of  customers  and  business  opportunities,  costs  associated  with 
maintaining business relationships after an attack or breach; significant business disruption to Comerica’s operations 
and  business,  misappropriation,  exposure,  or  destruction  of  its  confidential  information,  intellectual  property,  funds, 
and/or those of its customers; or damage to Comerica’s or Comerica’s customers’ and/or third parties’ computers or 
systems, and could result in a violation of applicable privacy laws and other laws, litigation exposure, regulatory fines, 
penalties or intervention, loss of confidence in Comerica’s security measures, reputational damage, reimbursement or 
other compensatory costs, additional compliance costs, and could adversely impact its results of operations, liquidity 
and  financial  condition.  In  addition,  although  Comerica  maintains  insurance  coverage  that  may  cover  certain  cyber 
losses (subject to policy terms and conditions), we may not have adequate insurance coverage to compensate for losses 
from a cybersecurity event.

•

Cybersecurity and data privacy are areas of heightened legislative and regulatory focus.

As cybersecurity and data privacy risks for banking organizations and the broader financial system have significantly 
increased in recent years, cybersecurity and data privacy issues have become the subject of increasing legislative and 
regulatory  focus.  The  federal  bank  regulatory  agencies  have  proposed  enhanced  cyber  risk  management  standards, 
which  would  apply  to  a  wide  range  of  large  financial  institutions  and  their  third-party  service  providers,  including 
Comerica  and  its  bank  subsidiaries,  and  would  focus  on  cyber  risk  governance  and  management,  management  of 
internal  and  external  dependencies,  and  incident  response,  cyber  resilience  and  situational  awareness.  Several  states 
have  also  proposed  or  adopted  cybersecurity  legislation  and  regulations,  which  require,  among  other  things, 

18

notification to affected individuals when there has been a security breach of their personal data. For more information 
regarding cybersecurity regulation, refer to the “Supervision and Regulation” section of this report.

Comerica receives, maintains and stores non-public personal information of Comerica’s customers and counterparties, 
including, but not limited to, personally identifiable information and personal financial information. The sharing, use, 
disclosure  and  protection  of  this  information  are  governed  by  federal  and  state  law.  Both  personally  identifiable 
information and personal financial information is increasingly subject to legislation and regulation, the intent of which 
is to protect the privacy of personal information that is collected and handled. For example, the CCPA applies to for-
profit businesses that conduct business in California and meet certain revenue or data collection thresholds, including 
Comerica. For more information regarding data privacy regulation, refer to the “Supervision and Regulation” section 
of this report.

Comerica may become subject to new legislation or regulation concerning cybersecurity or the privacy of personally 
identifiable  information  and  personal  financial  information  or  of  any  other  information  Comerica  may  store  or 
maintain. Comerica could be adversely affected if new legislation or regulations are adopted or if existing legislation 
or  regulations  are  modified  such  that  Comerica  is  required  to  alter  its  systems  or  require  changes  to  its  business 
practices  or  privacy  policies.  If  cybersecurity,  data  privacy,  data  protection,  data  transfer  or  data  retention  laws  are 
implemented, interpreted or applied in a manner inconsistent with Comerica’s current practices, it may be subject to 
fines, litigation or regulatory enforcement actions or ordered to change its business practices, policies or systems in a 
manner that adversely impacts Comerica’s operating results.

OPERATIONAL RISK

•

Comerica’s  operational  or  security  systems  or  infrastructure,  or  those  of  third  parties,  could  fail  or  be 
breached,  which  could  disrupt  Comerica’s  business  and  adversely  impact  Comerica’s  results  of  operations, 
liquidity and financial condition, as well as cause legal or reputational harm.

The potential for operational risk exposure  exists  throughout Comerica’s  business  and,  as  a  result  of  its interactions 
with,  and  reliance  on,  third  parties,  is  not  limited  to  Comerica’s  own  internal  operational  functions.  Comerica's 
operations  rely  on  the  secure  processing,  storage  and  transmission  of  confidential  and  other  information  on  its 
technology systems and networks. These networks are subject to infrastructure failures, ongoing system maintenance 
and  upgrades  and  planned  network  outages.  Comerica's  use  of  mobile  and  cloud  technologies,  as  well  as  its  hybrid 
work  options  permitting  remote  work,  can  heighten  these  and  other  operational  risks.  Any  failure,  interruption  or 
breach  in  security  of  these  systems  could  result  in  failures  or  disruptions  in  Comerica's  customer  relationship 
management, general ledger, deposit, loan and other systems. 

Comerica relies on its employees and third parties in its day-to-day and ongoing operations, who may, as a result of 
human error, misconduct, malfeasance or failure, or breach of Comerica’s or of third-party systems or infrastructure, 
expose  Comerica  to  risk.  For  example,  Comerica’s  ability  to  conduct  business  may  be  adversely  affected  by  any 
significant disruptions to Comerica or to third parties with whom Comerica interacts or upon whom it relies. Although 
Comerica has programs in place related to business continuity, disaster recovery and information security to maintain 
the  confidentiality,  integrity  and  availability  of  its  systems,  business  applications  and  customer  information,  such 
disruptions may still give rise to interruptions in service to customers and loss or liability to Comerica, including loss 
of customer data. In addition, Comerica’s ability to implement backup systems and other safeguards with respect to 
third-party systems is more limited than with respect to its own systems. 

Comerica’s  financial,  accounting,  data  processing,  backup  or  other  operating  or  security  systems  and  infrastructure 
may fail to operate properly or become disabled or damaged as a result of a number of factors, including events that 
are wholly or partially beyond its control, which could adversely affect its ability to process transactions or provide 
services.  Such  events  may  include  sudden  increases  in  customer  transaction  volume  and/or  customer  activity; 
electrical,  telecommunications  or  other  major  physical  infrastructure  outages;  natural  disasters  such  as  earthquakes, 
tornadoes,  hurricanes  and  floods;  disease  pandemics;  cyber  attacks;  and  events  arising  from  local  or  larger  scale 
political or social matters, including wars and terrorist acts. 

The occurrence of any failure or interruption in Comerica's operations or information systems, or any security breach, 
could cause reputational damage, jeopardize the confidentiality of customer information, result in a loss of customer 
business, subject Comerica to regulatory intervention or expose it to civil litigation and financial loss or liability, any 
of which could have a material adverse effect on Comerica. 

19

•

•

Comerica  relies  on  other  companies  to  provide  certain  key  components  of  its  delivery  systems,  and  certain 
failures could materially adversely affect operations.

Comerica faces the risk of operational disruption, failure or capacity constraints due to its dependency on third party 
vendors  for  components  of  its  delivery  systems.  Third  party  vendors  provide  certain  key  components  of  Comerica's 
delivery systems, such as cloud-based computing, networking and storage services, cash services, payment processing 
services, recording and monitoring services, internet connections and network access, clearing agency services, card 
processing services and trust processing services. While Comerica conducts due diligence prior to engaging with third 
party vendors and performs ongoing monitoring of vendor controls, it does not control their operations. Further, while 
Comerica's vendor management policies and practices are designed to comply with current regulations, these policies 
and  practices  cannot  eliminate  this  risk.  In  this  context,  any  vendor  failure  to  properly  deliver  these  services  could 
adversely  affect  Comerica’s  business  operations,  and  result  in  financial  loss,  reputational  harm,  and/or  regulatory 
action. 

Legal and regulatory proceedings and related matters with respect to the financial services industry, including 
those directly involving Comerica and its subsidiaries, could adversely affect Comerica or the financial services 
industry in general.

Comerica  has  been,  and  may  in  the  future  be,  subject  to  various  legal  and  regulatory  proceedings.  It  is  inherently 
difficult  to  assess  the  outcome  of  these  matters,  and  there  can  be  no  assurance  that  Comerica  will  prevail  in  any 
proceeding or litigation. Any such matter could result in substantial cost and diversion of Comerica's efforts, which by 
itself  could  have  a  material  adverse  effect  on  Comerica's  financial  condition  and  operating  results.  Further,  adverse 
determinations in such matters could result in fines or actions by Comerica's regulators that could materially adversely 
affect Comerica's business, financial condition or results of operations.

Comerica  establishes  reserves  for  legal  claims  when  payments  associated  with  the  claims  become  probable  and  the 
costs  can  be  reasonably  estimated.  Comerica  may  still  incur  legal  costs  for  a  matter  even  if  it  has  not  established  a 
reserve. In addition, due to the inherent subjectivity of the assessments and unpredictability of the outcome of legal 
proceedings, the actual cost of resolving a legal claim may be substantially higher than any amounts reserved for that 
matter.  The  ultimate  resolution  of  a  pending  legal  proceeding,  depending  on  the  remedy  sought  and  granted,  could 
adversely affect Comerica's results of operations and financial condition.

•

Comerica may incur losses due to fraud.

Fraudulent activity can take many forms and has escalated as more tools for accessing financial services emerge, such 
as real-time payments. Fraud schemes are broad and continuously evolving. Examples include but are not limited to: 
debit  card/credit  card  fraud,  check  fraud,  mechanical  devices  attached  to  ATM  machines,  social  engineering  and 
phishing  attacks  to  obtain  personal  information,  impersonation  of  clients  through  the  use  of  falsified  or  stolen 
credentials, employee fraud, information theft and other malfeasance. Increased deployment of technologies, such as 
chip  card  technology,  defray  and  reduce  aspects  of  fraud;  however,  criminals  are  turning  to  other  sources  to  steal 
personally  identifiable  information  in  order  to  impersonate  the  consumer  to  commit  fraud.  Many  of  these  data 
compromises  have  been  widely  reported  in  the  media.  Further,  as  a  result  of  the  increased  sophistication  of  fraud 
activity, Comerica continues to invest in systems, resources, and controls to detect and prevent fraud. This will result 
in continued ongoing investments in the future.

•

Controls and procedures may not prevent or detect all errors or acts of fraud.

Controls  and  procedures  are  designed  to  provide  reasonable  assurance  that  information  required  to  be  disclosed  in 
reports  Comerica  files  or  submits  under  the  Exchange  Act  is  accurately  accumulated  and  communicated  to 
management, and recorded, processed, summarized, and reported within the time periods specified in the SEC's rules 
and forms. Disclosure controls and procedures or internal controls and procedures, no matter how well conceived and 
operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met, due to 
certain inherent limitations. These limitations include the realities that judgments in decision making can be faulty, that 
alternative  reasoned  judgments  can  be  drawn,  that  breakdowns  can  occur  because  of  an  error  or  mistake,  or  that 
controls  may  be  fraudulently  circumvented.  Accordingly,  because  of  the  inherent  limitations  in  control  systems, 
misstatements due to error or fraud may occur and not be detected.

COMPLIANCE RISK

•

Changes  in  regulation  or  oversight,  or  changes  in  Comerica’s  status  with  respect  to  existing  regulations  or 
oversight, may have a material adverse impact on Comerica's operations.

Comerica is subject to extensive regulation, supervision and examination by the U.S. Treasury, the Texas Department 
of Banking, the FDIC, the FRB, the OCC, the CFPB, the CFTC, the SEC, FINRA, DOL, MSRB and other regulatory 

20

bodies. Such regulation and supervision governs and limits the activities in which Comerica may engage. Regulatory 
authorities  have  extensive  discretion  in  their  supervisory  and  enforcement  activities,  including  the  imposition  of 
restrictions  on  Comerica's  operations  and  ability  to  make  acquisitions,  investigations  and  limitations  related  to 
Comerica's securities, the classification of Comerica's assets and determination of the level of Comerica's allowance 
for  loan  losses.  Any  change  in  such  regulation  and  oversight,  whether  in  the  form  of  regulatory  policy,  regulations, 
legislation, changed interpretations or supervisory action, may have a material adverse impact on Comerica's business, 
financial condition or results of operations. The impact of any future legislation or regulatory actions may adversely 
affect Comerica's businesses or operations.

Further,  even  if  such  regulations  or  oversight  do  not  change,  Comerica's  business  may  develop  such  that  it  may  be 
subject to increased regulatory requirements. For example, if Comerica's asset size increases in the future and exceeds 
$100  billion  in  average  total  consolidated  assets  calculated  over  four  consecutive  financial  quarters,  Comerica  will 
become a Category IV institution. Category IV institutions ($100 to $250 billion in assets) under the Tailoring Rules 
are  subject  to  additional  requirements,  such  as  certain  enhanced  prudential  standards  and  monitoring  and  reporting 
certain  risk-based  indicators.  Under  the  Tailoring  Rules,  Category  IV  firms  are,  among  other  things,  subject  to  (1) 
supervisory  capital  stress  testing  on  a  biennial  basis,  (2)  requirements  to  develop  and  maintain  a  capital  plan  on  an 
annual basis and (3) certain liquidity risk management and risk committee requirements, including liquidity buffer and 
liquidity  stress  testing  requirements.  Comerica  would  also  incur  additional  assessments  under  Regulation  TT.  If 
Comerica becomes subject to enhanced prudential standards, it will face more stringent requirements or limitations on 
its  business,  as  well  as  increased  compliance  costs,  and,  depending  on  its  levels  of  capital  and  liquidity,  stress  test 
results and other factors, may be limited in the types of activities it may conduct and be limited as to how it utilizes 
capital.  Further,  Comerica  may  be  subject  to  heightened  expectations,  which  could  result  in  additional  regulatory 
scrutiny,  higher  penalties,  and  more  severe  consequences  if  it  is  unable  to  meet  those  expectations.  In  particular,on 
July  27,  2023,  the  FRB,  the  FDIC,  and  the  OCC  issued  a  proposal,  referred  to  as  “Basel  III  Endgame,”  that  would 
result in significant changes to the U.S. regulatory capital rules for banking organizations with total consolidated assets 
of $100 billion or more. As of December 31, 2023, the Corporation had total assets of $85.8 billion. While Basel III 
Endgame would not apply to Comerica as currently proposed, if Comerica becomes subject to those requirements or 
becomes subject  to any other  new laws or regulations  related  to  capital and  liquidity,  such requirements  could limit 
Comerica’s  ability  to  pay  dividends  or  make  share  repurchases  or  require  Comerica  to  reduce  business  levels  or  to 
raise capital, which would have a material adverse effect on Comerica’s financial condition and results of operations.

•

Compliance with stringent capital requirements may adversely affect Comerica.

Comerica is required to satisfy stringent regulatory capital standards, as set forth in the “Supervision and Regulation” 
section of this report. These requirements, and any other new laws or regulations related to capital and liquidity, or any 
existing requirements that Comerica becomes subject to as a result of its increased asset size, could adversely affect 
Comerica's ability to pay dividends or make share repurchases, or could require Comerica to reduce business levels or 
to  raise  capital,  including  in  ways  that  may  adversely  affect  its  results  of  operations  or  financial  condition  and/or 
existing  shareholders.  Maintaining  higher  levels  of  capital  may  reduce  Comerica's  profitability  and  otherwise 
adversely affect its business, financial condition, or results of operations.

•

Changes  to  tax  law  or  regulations,  or  changes  to  administrative  or  judicial  interpretations  of  tax  law 
regulations, could adversely affect Comerica. 

Federal income tax treatment of corporations may be clarified and/or modified by legislative, administrative or judicial 
changes or interpretations at any time. Any such changes could adversely affect Comerica, either directly, or indirectly 
as a result of effects on Comerica's customers. 

STRATEGIC RISK

•

Damage to Comerica’s reputation could damage its businesses.

Reputational risk is an increasing concern for businesses as customers are interested in doing business with companies 
they admire and trust. Such risks include compliance issues, operational challenges, or a strategic, high profile event. 
Comerica's  business  is  based  on  the  trust  of  its  customers,  communities,  and  entire  value  chain,  which  makes 
managing  reputational  risk  extremely  important.  News  or  other  publicity  that  impairs  Comerica's  reputation,  or  the 
reputation of the financial services industry generally, can therefore cause significant harm to Comerica’s business and 
prospects.  Further,  adverse  publicity  or  negative  information  posted  on  social  media  websites  regarding  Comerica, 
whether or not true, may result in harm to Comerica’s prospects.

Comerica may not be able to utilize technology to efficiently and effectively develop, market, and deliver new 
products and services to its customers. 

The financial services industry experiences rapid technological change with regular introductions of new technology-
driven products and services. The ability to access and use technology is an increasingly important competitive factor 
in  the  financial  services  industry,  and  having  the  right  technology  is  a  critically  important  component  to  customer 
satisfaction. As well, the efficient and effective utilization of technology enables financial institutions to reduce costs. 
Comerica's future success depends, in part, upon its ability to address the needs of its customers by using technology to 
market and deliver products and services that will satisfy customer demands, meet regulatory requirements, and create 
additional  efficiencies  in  Comerica's  operations.  Comerica  may  not  be  able  to  effectively  develop  new  technology-
driven products and services or be successful in marketing or supporting these products and services to its customers, 
which could have a material adverse impact on Comerica's financial condition and results of operations.

•

Competitive product and pricing pressures within Comerica's markets may change.

Comerica operates in a very competitive environment, which is characterized by competition from a number of other 
financial institutions in each market in which it operates. Comerica competes largely on the basis of industry expertise, 
the range of products and services offered, pricing and reputation, convenience, quality of service, responsiveness to 
customer needs and the overall customer relationship. Comerica's competitors include financial institutions of all sizes. 
Some  of  Comerica's  larger  competitors,  including  certain  nationwide  banks  that  have  a  significant  presence  in 
Comerica's markets, may have a broader array of products and structure alternatives and, due to their size, may more 
easily absorb credit losses. Some of Comerica's competitors (larger or smaller) may have more liberal lending policies 
and  and  aggressive  pricing  standards  for  loans,  deposits  and  services.  Increasingly,  Comerica  competes  with  other 
companies based on financial technology and capabilities, such as mobile banking applications and funds transfer. 

Additionally,  the  financial  services  industry  is  subject  to  extensive  regulation.  For  more  information,  see  the 
“Supervision and Regulation” section of this report. Such regulations may require significant additional investments in 
technology,  personnel  or  other  resources  or  place  limitations  on  the  ability  of  financial  institutions,  including 
Comerica,  to  engage  in  certain  activities.  Comerica's  competitors  may  be  subject  to  significantly  different  or  lesser 
regulation  due  to  their  asset  size  or  types  of  products  offered.  Some  competitors  may  also  have  the  ability  to  more 
efficiently  utilize  resources  to  comply  with  regulations  or  may  be  able  to  more  effectively  absorb  the  cost  of 
regulations. 

In  addition  to  banks,  Comerica  and  its  banking  subsidiaries  also  face  competition  from  financial  intermediaries, 
including  savings  and  loan  associations,  consumer  and  commercial  finance  companies,  leasing  companies,  venture 
capital funds, credit unions, investment banks, insurance companies and securities firms. Competition among providers 
of financial products and services continues to increase as technology advances have lowered the barriers to entry for 
financial technology companies, with customers having the opportunity to select from a growing variety of traditional 
and  nontraditional  alternatives,  including  crowdfunding,  digital  wallets  and  money  transfer  services.  The  ability  of 
non-banks to provide services previously limited to traditional banks has intensified competition. Because non-banks 
are  not  subject  to  many  of  the  same  regulatory  restrictions  as  banks  and  bank  holding  companies,  they  can  often 
operate with greater flexibility and lower cost structures. 

If  Comerica  is  unable  to  compete  effectively  in  products  and  pricing  in  its  markets,  business  could  decline,  which 
could have a material adverse effect on Comerica's business, financial condition or results of operations.

•

The introduction, implementation, withdrawal, success and timing of business initiatives and strategies may be 
less successful or may be different than anticipated, which could adversely affect Comerica's business.

Comerica  makes  certain  projections  and  develops  plans  and  strategies  for  its  banking  and  financial  products.  If 
Comerica  does  not  accurately  determine  demand  for  its  banking  and  financial  product  needs,  it  could  result  in 
Comerica incurring significant expenses without the anticipated increases in revenue, which could result in a material 
adverse effect on its business. Comerica has expanded its presence in the Southeastern and Mountain West regions of 
the U.S.; if Comerica's expansion is not successful, it could adversely impact Comerica's expenses. Comerica recently 
put in place a strategic relationship with Ameriprise to become Comerica’s new investment program provider; if the 
relationship is not successful, it could adversely impact Comerica's reputation or results.

•

Management's ability to maintain and expand customer relationships may differ from expectations.

The  financial  services  industry  is  very  competitive.  Comerica  not  only  vies  for  business  opportunities  with  new 
customers,  but  also  competes  to  maintain  and  expand  the  relationships  it  has  with  its  existing  customers.  While 
management believes that it can continue to grow many of these relationships, Comerica will continue to experience 
pressures  to  maintain  these  relationships  as  its  competitors  attempt  to  capture  its  customers.  Failure  to  create  new 

22

customer  relationships  and  to  maintain  and  expand  existing  customer  relationships  to  the  extent  anticipated  may 
adversely impact Comerica's earnings.

•

Management's ability to retain key officers and employees may change.

Comerica's future operating results depend substantially upon the continued service of its executive officers and key 
personnel.  Comerica's  future  operating  results  also  depend  in  significant  part  upon  its  ability  to  attract  and  retain 
qualified  management,  financial,  technical,  marketing,  sales  and  support  personnel.  Competition  for  qualified 
personnel is intense, and Comerica cannot ensure success in attracting or retaining qualified personnel. There may be 
only  a  limited  number  of  persons  with  the  requisite  skills  to  serve  in  these  positions,  and  it  may  be  increasingly 
difficult  for  Comerica  to  hire  personnel  over  time.  The  increased  prevalence  of  remote  work  environments  has 
intensified the competition for talent as job opportunities may be less constrained by physical geography.

Further,  Comerica's  ability  to  retain  key  officers  and  employees  may  be  impacted  by  legislation  and  regulation 
affecting the financial services industry. In 2016, the FRB, OCC and several other federal financial regulators revised 
and  re-proposed  rules  to  implement  Section  956  of  the  Dodd-Frank  Act.  Section  956  directed  regulators  to  jointly 
prescribe  regulations  or  guidelines  prohibiting  incentive-based  payment  arrangements,  or  any  feature  of  any  such 
arrangement, at covered financial institutions that encourage inappropriate risks by providing excessive compensation 
or that could lead to a material financial loss. Consistent with the Dodd-Frank Act, the proposed rule would impose 
heightened standards for institutions with $50 billion or more in total consolidated assets, which includes Comerica. 
For  these  larger  institutions,  the  proposed  rule  would  require  the  deferral  of  at  least  40  percent  of  incentive-based 
payments  for  designated  executives  and  significant  risk-takers  who  individually  have  the  ability  to  expose  the 
institution  to  possible  losses  that  are  substantial  in  relation  to  the  institution's  size,  capital  or  overall  risk  tolerance. 
Moreover, incentive-based compensation of these individuals would be subject to potential clawback for seven years 
following vesting. Further, the rule imposes enhanced risk management controls and governance and internal policy 
and procedure requirements with respect to incentive compensation. Accordingly, Comerica may be at a disadvantage 
to offer competitive compensation compared to other financial institutions (as referenced above) or companies in other 
industries, which may not be subject to the same requirements. 

Comerica's business, financial condition or results of operations could be materially adversely affected by the loss of 
any of its key employees, or Comerica's inability to attract and retain skilled employees.

•

Any  future  strategic  acquisitions  or  divestitures  may  present  certain  risks  to  Comerica's  business  and 
operations.

Difficulties  in  capitalizing  on  the  opportunities  presented  by  a  future  acquisition  may  prevent  Comerica  from  fully 
achieving the expected benefits from the acquisition, or may cause the achievement of such expectations to take longer 
to realize than expected. 

Further, the assimilation of any acquired entity's customers and markets could result in higher than expected deposit 
attrition,  loss  of  key  employees,  disruption  of  Comerica's  businesses  or  the  businesses  of  the  acquired  entity  or 
otherwise adversely affect Comerica's ability to maintain relationships with customers and employees or achieve the 
anticipated benefits of the acquisition. These matters could have an adverse effect on Comerica for an undetermined 
period. Comerica would be subject to similar risks and difficulties in connection with any future decisions to downsize, 
sell or close units or otherwise change the business mix of Comerica.

GENERAL RISK

•

General political, economic or industry conditions, either domestically or internationally, may be less favorable 
than expected.

Economic, financial  market, political, and industry-specific developments may  affect  the financial  services industry, 
both  directly  and  indirectly.  The  economic  environment  and  market  conditions  in  which  Comerica  operates,  at  the 
local, domestic, and international levels, continue to be uncertain. The U.S. economy faces uncertainties from elevated 
interest rates, persistent inflation, the end of fiscal stimulus, subdued housing market activity and weak export demand. 
It  also  faces  downside  risks  from  geopolitical  conflicts  around  the  globe,  including  those  involving  Venezuela;  the 
Israel-Hamas War and its spread to Yemen, Lebanon, and/or other parts of the Middle East; the Ukraine-Russia War 
and its effects in Europe; tensions between Taiwan and mainland China; threats from North Korea; and the possibility 
of other geopolitical shocks.

Domestically, the elevated budget deficit, the possibility of a federal government shutdown and/or debt ceiling crisis, 
as well as broader issues surrounding the federal  budgeting  process and  governance, may  contribute  to  a possibility 
downgrade  of  the  U.S.  sovereign  credit  rating,  potentially  causing  knock-on  effects  for  the  broader  economy  and 
financial system that could include a recession. 

23

The Federal Reserve has rapidly tightened monetary policies during the recovery from the 2020 recession, including 
both increases in interest rates and reductions in the size of the central bank’s balance sheet, which contribute to the 
risk of a monetary policy error.

Fiscal and industrial policies to support the growth of targeted industries could have unanticipated effects or change 
unexpectedly, causing volatility in the economic performance of these industries or other parts of the economy. These 
effects could impact the energy industry, manufacturing, construction, auto manufacturing and retailing, or potentially 
other  industries.  Prices  of  energy  products  and  services,  as  well  as  other  commodities,  are  subject  to  large  and 
unanticipated  fluctuations  caused  by  changes  to  supply  and  demand  conditions,  which  could  directly  or  indirectly 
affect Comerica’s business and/or clients.

Rapid  changes  to  the  economy  have  impacted  demand  for  residential  and  commercial  real  estate,  including  single-
family and multifamily residential properties, as well as office, industrial, and retail commercial real estate properties. 
These  changes  could  affect  the  economic  health  of  downtowns  in  major  cities  and  other  regions  where  economic 
activity has changed in recent years, and could impact real estate prices, construction activity, and/or sales. 

Adverse economic conditions related a potential recession, including changes in inflation, unemployment, or interest 
rates,  may,  directly  and  indirectly,  adversely  affect  Comerica.  Furthermore,  changes  in  trade  policies  or  other 
economic  policies,  state  and  local  municipal  finances,  federal  government  finances  and  the  U.S.  federal  debt,  are 
outside of our control and may affect the operating environment affecting Comerica.

•

Inflation could negatively impact Comerica's business, profitability and stock price.

Prolonged periods of inflation may impact Comerica profitability by negatively impacting its fixed costs and expenses, 
including increasing funding costs and expense related to talent acquisition and retention, and negatively impacting the 
demand for its products and services. Additionally, inflation may lead to a decrease in consumer and clients purchasing 
power  and  negatively  affect  the  need  or  demand  for  Comerica's  products  and  services.  If  significant  inflation 
continues, Comerica's business could be negatively affected by, among other things, increased default rates leading to 
credit losses which could decrease the appetite for new credit extensions. These inflationary pressures could result in 
missed earnings and budgetary projections causing Comerica's stock price to suffer.

•

Methods of reducing risk exposures might not be effective.

The Corporation assumes various types of risk as a result of conducting business in the normal course. Instruments, 
systems  and  strategies  used  to  hedge  or  otherwise  manage  exposure  to  various  types  of  credit,  market,  liquidity, 
technology,  operational,  compliance,  financial  reporting  and  strategic  risks  could  be  less  effective  than  anticipated. 
The  Corporation's  enterprise  risk  management  framework  provides  a  process  for  identifying,  measuring,  controlling 
and  managing  risks,  and  Comerica's  management  expends  significant  effort  and  resources  in  risk  management. 
Nevertheless, Comerica may not be able to effectively mitigate its risk exposures in particular market environments or 
against  particular  types  of  risk,  which  could  have  a  material  adverse  impact  on  Comerica's  business,  financial 
condition  or  results  of  operations.  The  Corporation  also  utilizes  various  asset  and  liability  management  strategies  to 
manage net interest income exposure to interest rate risk; these may not always be completely effective. 

For  more  information  regarding  risk  management,  please  see  "Risk  Management"  in  the  Financial  Section  of  this 
report.

•

Catastrophic  events,  including  pandemics,  may  adversely  affect  the  general  economy,  financial  and  capital 
markets, specific industries, and Comerica.

Acts of terrorism, cyber-terrorism, political unrest, war, civil disturbance, armed regional and international hostilities 
and  international  responses  to  these  hostilities,  natural  disasters  (including  tornadoes,  hurricanes,  earthquakes,  fires, 
droughts and floods), global health risks or pandemics, or the threat of or perceived potential for these events could 
have a negative impact on us. Comerica’s business continuity and disaster recovery plans may not be successful upon 
the occurrence of one of these scenarios, and a significant catastrophic event anywhere in the world could materially 
adversely affect Comerica's operating results.

In particular, certain of the regions where Comerica operates, including California, Texas, and Florida, are known for 
being  vulnerable  to  natural  disasters.  These  types  of  natural  catastrophic  events  have  at  times  disrupted  the  local 
economies,  Comerica's  business  and  customers,  and  have  caused  physical  damage  to  Comerica's  property  in  these 
regions. 

Dangerous,  potentially  deadly,  and  easily-transmitted  viruses  and  other  pathogens,  and  government  and  social 
reactions to such epidemics and pandemics have affected, and may again affect, international trade (including supply 
chains  and  export  levels),  travel,  employee  productivity,  and  other  economic  activities.  These  potential  events  may 

24

•

•

•

negatively  impact  Comerica's  and/or  its  clients’  costs,  demand  for  its  clients’  products,  and/or  the  U.S.  economy  or 
certain sectors thereof and, thus, adversely affect Comerica's business, financial condition, and results of operations.

Further, catastrophic events may have an impact on Comerica's customers and in turn, on Comerica. 

In  addition,  these  events  have  had  and  may  continue  to  have  an  adverse  impact  on  the  U.S.  and  world  economy  in 
general and consumer confidence and spending in particular, which could harm Comerica's operations. Any of these 
events could increase volatility in the U.S. and world financial markets, which could harm Comerica's stock price and 
may limit the capital resources available to Comerica and its customers. This could have a material adverse impact on 
Comerica's  operating  results,  revenues  and  costs  and  may  result  in  increased  volatility  in  the  market  price  of 
Comerica's common stock.

Climate  change  manifesting  as  physical  or  transition  risks  could  adversely  affect  Comerica's  operations, 
businesses and customers.

There is an increasing concern over the risks of climate change and related environmental sustainability matters. The 
physical  risks  of  climate  change  include  discrete  events,  such  as  flooding  and  wildfires,  and  longer  term  shifts  in 
climate  patterns,  such  as  extreme  heat,  sea  level  rise,  and  more  frequent  and  prolonged  drought.  Such  events  could 
disrupt Comerica's operations or those of its clients or third parties on which it relies, including through direct damage 
to assets and indirect impacts from supply chain disruption and market volatility. Additionally, transitioning to a low 
carbon  economy  may  entail  extensive  policy,  legal,  technology,  and  market  initiatives.  Transition  risks,  including 
changes  in  consumer  preferences  and  additional  regulatory  requirements  or  taxes,  could  increase  expenses  and 
undermine business strategies. In addition, Comerica's reputation and client relationships may be damaged as a result 
of  practices  related  to  climate  change,  including  its  involvement,  or  its  clients’  involvement,  in  certain  industries  or 
projects associated with causing or exacerbating climate change, as well as any decisions Comerica makes to continue 
to  conduct  or  change  its  activities  in  response  to  considerations  relating  to  climate  change,  including  the  setting  of 
climate-related goals, commitments and targets. As climate risk is interconnected with all key risk types, Comerica is 
advancing  its  processes  to  embed  climate  risk  considerations  into  risk  management  strategies  such  as  market,  credit 
and  operational  risks;  however,  because  the  timing  and  severity  of  climate  change  may  not  be  predictable,  risk 
management strategies may not be effective in mitigating climate risk exposure.

Changes in accounting standards could materially impact Comerica's financial statements. 

From time to time accounting standards setters change the financial accounting and reporting standards that govern the 
preparation  of  Comerica’s  financial  statements.  These  changes  can  be  difficult  to  predict  and  can  materially  impact 
how Comerica records and reports its financial condition and results of operations. In some cases, Comerica could be 
required to apply a new or revised standard retroactively, resulting in changes to previously reported financial results, 
or a cumulative charge to retained earnings. 

Comerica's accounting estimates and processes are critical to the reporting of financial condition and results of 
operations. They require management to make estimates about matters that are uncertain. 

Accounting estimates and processes are fundamental to how Comerica records and reports its financial condition and 
results  of  operations.  Management  must  exercise  judgment  in  selecting  and  applying  many  of  these  accounting 
estimates  and  processes  so  they  comply  with  U.S.  Generally  Accepted  Accounting  Principles  ("GAAP").  In  some 
cases, management must select an accounting policy or method to apply from two or more alternatives, any of which 
may be reasonable under the circumstances, yet may result in the Company reporting materially different results than 
would have been reported under a different alternative.

Management has identified certain accounting estimates as being critical because they require management's judgment 
to make difficult, subjective or complex judgments about matters that are uncertain. Materially different amounts could 
be reported under different conditions or using different assumptions or estimates. Comerica has established detailed 
policies and control procedures that are intended to ensure these critical accounting estimates and judgments are well 
controlled and applied consistently. In addition, the policies and procedures are intended to ensure that the process for 
changing  methodologies  occurs  in  an  appropriate  manner.  Because  of  the  uncertainty  surrounding  management's 
judgments  and  the  estimates  pertaining  to  these  matters,  Comerica  cannot  guarantee  that  it  will  not  be  required  to 
adjust accounting policies or restate prior period financial statements. For example, our allowances for credit losses, 
fair value measurement, goodwill valuation and impairment, pension plan accounting, and provisions for income taxes 
may prove faulty or inaccurate. See “Critical Accounting Estimates” in the Financial Section of this report and Note 1 
of the Notes to Consolidated Financial Statements in the Financial Section of this report.

Comerica's stock price can be volatile.

Stock price volatility may make it more difficult for shareholders to resell their common stock when they want and at 
prices  they  find  attractive.  Comerica's  stock  price  can  fluctuate  significantly  in  response  to  a  variety  of  factors 
including, among other things:

•
•
•
•
•
•
•

•
•
•
•
•

Actual or anticipated variations in quarterly results of operations.
Recommendations or projections by securities analysts.
Operating and stock price performance of other companies that investors deem comparable to Comerica.
News reports relating to trends, concerns and other issues in the financial services industry.
Perceptions in the marketplace regarding Comerica and/or its competitors.
New technology used, or services offered, by competitors.
Significant  acquisitions  or  business  combinations,  strategic  partnerships,  joint  ventures  or  capital 
commitments by or involving Comerica or its competitors.
Changes in dividends and capital returns.
Changes in government regulations.
Cyclical fluctuations.
Geopolitical conditions such as acts or threats of terrorism or military conflicts.
Activity by short sellers and changing government restrictions on such activity.

General market fluctuations, including real or anticipated changes in the strength of the economy; industry factors and 
general  economic  and  political  conditions  and  events,  such  as  economic  slowdowns  or  recessions;  interest  rate 
changes,  oil  price  volatility  or  credit  loss  trends,  among  other  factors,  could  also  cause  Comerica's  stock  price  to 
decrease regardless of operating results.

For the above and other reasons, the market price of Comerica's securities may not accurately reflect the underlying 
value of the securities, and investors should consider this before relying on the market prices of Comerica's securities 
when making an investment decision.

•

An investment in Comerica's equity securities is not insured or guaranteed by the FDIC.

Investments  in  Comerica’s  common  or  preferred  stock  are  not  deposits  or  other  obligations  of  a  bank  or  savings 
association and are not insured or guaranteed by the FDIC or any other governmental agency.

Item 1B.  Unresolved Staff Comments.

None.

Item 1C.  Cybersecurity.

Managing technology risks, including risks related to cybersecurity, is an integral part of Comerica’s enterprise risk 
management framework and processes. As such, Comerica uses a library of processes, risks and controls to assess, identify and 
manage cybersecurity risks. Comerica measures such risks in part by estimating the likelihood and potential impact of incidents. 
Comerica  seeks  to  manage  such  these  risks  by  designing,  documenting,  and  implementing  controls,  testing  those  controls 
through compliance assessments and internal and external audits and, in some cases, by transferring the risk in whole or in part 
through methods such as insurance. When an incident occurs, Comerica works to remediate the incident while complying with 
its  regulatory  obligations,  and  then  evaluate  the  remediation  for  effectiveness.  Comerica  communicates  on  risk  management 
matters  through  documented  policies  and  procedures,  management  and  Board  committee  reporting,  and  training  and  other 
employee communications.

For a description of how cybersecurity risks may materially affect Comerica’s business strategy or results, see "Item 
1A. Risk Factors.” No cybersecurity threat risks during the fiscal year ended December 31, 2023 materially affected or were 
reasonably likely to materially affect Comerica’s financial condition or results of operations.

Comerica engages information technology risk management employees with experience and expertise in cybersecurity. 
The organization consists of professionals in identity and access management, cyber defense operations, security engineering 
and information technology governance, risk and compliance. An Executive Vice President/ Chief Information Security Officer 
(with  over  25  years’  experience  in  cybersecurity  risk  management)  and  a  Chief  Information  Officer  (with  over  27  years’ 
experience in technology risk management) lead this team. Each reports directly to the Senior Executive Vice President / Chief 
Operating  Officer,  who  reports  directly  to  Comerica’s  Chief  Executive  Officer  and  the  Board  of  Directors.  In  addition, 
Comerica engages third parties from time to time to assess, manage and respond to cybersecurity risks through risk assessment, 
penetration testing, incident response, threat intelligence, education, and managed security services.

26

Comerica also oversees and identifies risks from threats to third parties, such as service providers, through efforts such 

as monitoring, risk assessments, audits, contractual due diligence and third-party security standards.

Senior  management  at  Comerica  governs  risk  management  and  is  informed  about,  and  monitors  the  prevention, 
detection, mitigation and mediation of cybersecurity incidents, in part through working review committees on which our Chief 
Information Security Officer and/or Chief Information Officer serve. Each review committee receives risk management reports 
appropriate  to  its  scope  of  review,  covering  matters  such  as  assessment  results,  risk  ratings  and  critical  issues.  They  report 
significant  matters  to  enterprise-wide  risk  committees  overseeing  the  broad  scope  of  risk  management  for  the  enterprise  as 
appropriate. Through these and other efforts, senior management makes decisions and sets priorities in allocating resources to 
address risk management issues.

The  Board’s  Enterprise  Risk  Committee  oversees  all  of  Comerica’s  risk  management  policies,  procedures  and 
practices, including those related to cybersecurity. Senior management generally reports quarterly, or more often as necessary, 
to the Enterprise Risk Committee on technology risks, including risks from cybersecurity threats. The Board’s Audit Committee 
and the Board as a whole also receive such reports as part of their risk management oversight roles. Board members have direct 
access to senior management (and others, at their request) on matters related to cybersecurity threats and may direct questions 
to senior management and request further information as they see fit to fulfill their oversight responsibilities.

Item 15.  Exhibits and Financial Statement Schedules.

Note  Regarding  Reliance  on  Statements  in  Our  Contracts  and  Other  Exhibits:  We  include  agreements  and  other 
exhibits to this Annual Report on Form 10-K to provide information regarding their terms and not to provide any other factual 
or disclosure information about us, our subsidiaries or affiliates, or the other parties to the agreements, or for any other purpose. 
The agreements and other exhibits contain representations and warranties by each of the parties to the applicable agreement. 
These representations and warranties have been made solely for the benefit of the other parties to the applicable agreement or 
other arrangement and (i) should not in all instances be treated as categorical statements of fact, but rather as a way of allocating 
the risk to one of the parties if those statements prove to be inaccurate; (ii) have in many cases been qualified by disclosures that 
were  made  to  the  other  party  in  connection  with  the  negotiation  of  the  applicable  agreement,  which  disclosures  are  not 
necessarily  reflected  in  the  agreement;  (iii)  may  apply  standards  of  materiality  in  a  way  that  is  different  from  what  may  be 
viewed as material to investors; and (iv) were made only as of the date of the applicable agreement or other exhibit, or such 
other  date  or  dates  as  may  be  specified  in  the  document  and  are  subject  to  more  recent  developments.  Accordingly,  these 
representations and warranties may not describe the actual state of affairs as of the date they were made or at any other time.

Comerica  Incorporated  (the  Corporation)  is  a  financial  holding  company  headquartered  in  Dallas,  Texas.  The 
Corporation's major business segments are the Commercial Bank, the Retail Bank and Wealth Management. Information about 
the activities of the Corporation's business segments is provided in Note 22 to the consolidated financial statements.

As a financial institution, the Corporation's principal activity is lending to and accepting deposits from businesses and 
individuals.  The  primary  source  of  revenue  is  net  interest  income,  which  is  principally  derived  from  the  difference  between 
interest earned on loans and investment securities and interest paid on deposits and other funding sources. The Corporation also 
provides  other  products  and  services  that  meet  the  financial  needs  of  customers  which  generate  noninterest  income,  the 
Corporation's  secondary  source  of  revenue.  Growth  in  loans,  deposits  and  noninterest  income  is  affected  by  many  factors, 
including  economic  conditions  in  the  markets  the  Corporation  serves,  the  financial  requirements  and  economic  health  of 
customers and the ability to add new customers and/or increase the number of products used by current customers. Success in 
providing products and services depends on the financial needs of customers and the types of products desired.

The accounting and reporting policies of the Corporation and its subsidiaries conform to generally accepted accounting 
principles (GAAP) in the United States (U.S.). The Corporation's consolidated financial statements are prepared based on the 
application  of  accounting  policies,  the  most  significant  of  which  are  described  in  Note  1  to  the  consolidated  financial 
statements.  When  necessary,  the  Corporation  uses  reasonable  assumptions  to  develop  estimates  that  affect  the  consolidated 
results of operations. The most critical of these estimates are discussed in the “Critical Accounting Estimates” section of this 
financial review. 

Full-Year 2023 compared to Full-Year 2022 

•

•
•

•

•

•

•

•

•

•

•

Net  income  decreased  $270  million  to  $881  million,  driven  by  increases  in  noninterest  expenses  and  provision  for 
credit losses, partially offset by an increase in net interest income due to higher short-term rates and loan growth.
Diluted net income per common share was $6.44 in 2023 compared to $8.47 in 2022. 
Average loans increased $3.4 billion, or 7 percent, to $53.9 billion, and included increases in Commercial Real Estate, 
National  Dealer  Services,  Corporate  Banking,  Wealth  Management  and  Environmental  Services,  partially  offset  by 
declines in Mortgage Banker Finance related to the planned exit from this line of business and Equity Fund Services.
Average securities decreased $1.6 billion, or 8 percent, to $17.4 billion, reflecting unrealized losses and maturities of 
Treasury securities, partially offset by the full-year impact of mortgage-backed securities purchased during 2022.
Average deposits decreased $9.5 billion, or 13 percent, to $66.0 billion. Average noninterest-bearing deposits, which 
decreased  $11.1  billion,  or  27  percent,  were  impacted  by  customer  diversification  efforts  following  the  banking 
industry disruption in the first quarter of 2023, partially offset by an increase in average interest-bearing deposits of 
$1.7 billion, or 5 percent, primarily due to increases in brokered time deposits and customer certificates of deposit.
Average  short-term  borrowings  increased  $6.8  billion  to  $7.2  billion,  while  average  medium-  and  long-term  debt 
increased $3.0 billion to $5.8 billion, reflecting higher Federal Home Loan Bank (FHLB) advances.
Net interest income increased $48 million to $2.5 billion, and the net interest margin increased 4 basis points to 3.06 
percent,  largely  due  to  higher  short-term  rates  and  average  loan  growth,  partly  offset  by  an  increase  in  average 
borrowings and interest-bearing deposits. 
The  provision  for  credit  losses  increased  $29  million  to  $89  million,  reflecting  average  loan  growth,  an  uncertain 
economic outlook and credit migration, as well as changes in portfolio composition.
Noninterest income increased $10 million to $1.1 billion, reflecting increases in deferred compensation asset returns 
(offset in noninterest expenses), FHLB stock dividends, brokerage fees, card fees, commercial lending fees and letter 
of credit fees, partially offset by decreases in risk management hedging income, service charges on deposit accounts 
and capital markets income.
Noninterest  expenses  increased  $361  million  to  $2.4  billion,  primarily  due  to  increases  in  FDIC  insurance  expense, 
salaries and benefits expense, non-salary pension expense, outside processing fee expense, litigation and regulatory-
related expenses, consulting fees, software expense and legal fees, partially offset by gains on the sale of real estate 
during the current year. 
The  Corporation  declared  common  dividends  of  $2.84  per  share,  returning  $375  million  to  common  shareholders. 
Additionally, the Corporation declared $23 million in preferred dividends.

The  following  provides  a  comparative  discussion  of  the  Corporation's  consolidated  results  of  operations  for  2023 
compared to 2022. A comparative discussion of results for 2022 compared to 2021 is provided in the "Results of Operations" 
section beginning on page F-3 of the Corporation's 2022 Annual Report.

Impact  of  other  portfolio  dynamics  and  interest  rate  swaps  reflected  as  part  of  rate  impact,  rate/volume  variances  are  allocated  to 
variances due to volume.

Net interest income is the difference between interest earned on assets and interest paid on liabilities. Gains and losses 
related to risk management interest rate swaps that convert fixed rate debt to a floating rate and qualify as fair value hedges are 
included in interest expense on medium- and long-term debt. Additionally, the portion of gains and losses on risk management 
interest rate swaps that convert variable-rate loans to fixed rates through cash flow hedges that relate to the earnings effect of 
the hedged loans during the period are included in loan interest income. 

Refer to the Analysis of Net Interest Income and the Rate/Volume Analysis tables above for an analysis of net interest 
income  for  the  years  ended  December  31,  2023,  2022  and  2021  and  details  of  the  components  of  the  change  in  net  interest 
income for 2023 compared to 2022 as well as 2022 compared to 2021.

Net interest income was $2.5 billion for the year ended December 31, 2023, an increase of $48 million compared to the 
year ended December 31, 2022. The increase in net interest income reflected the net benefit from higher short-term rates and 
loan growth, partially offset by increased balances of interest-bearing deposits and borrowings. Net interest margin increased 4 
basis points to 3.06 percent for the year ended December 31, 2023, reflecting higher short-term rates, partially offset by higher- 
cost funding sources.

Average earning assets of $79.2 billion were relatively stable compared to the prior year and included $3.4 billion in 
loan growth, partially offset by declines of $1.8 billion in interest-bearing deposits with banks and $1.6 billion in investment 
securities.  Average  interest-bearing  funding  sources  increased  $11.5  billion,  driven  by  increases  of  $6.8  billion  in  short-term 
borrowings, $3.0 billion in medium- and long-term debt and $1.7 billion in interest-bearing deposits.

The Corporation utilizes various asset and liability management strategies to manage net interest income exposure to 
interest rate risk. Refer to the “Market and Liquidity Risk” section of this financial review for additional information regarding 
the  Corporation's  asset  and  liability  management  policies  and  the  “Balance  Sheet  and  Capital  Funds  Analysis”  section  for 
further discussion on changes in earning assets and interest-bearing liabilities.

Provision for Credit Losses

The  provision  for  credit  losses  increased  $29  million  to  $89  million,  reflecting  average  loan  growth,  an  uncertain 
economic outlook and credit migration, as well as changes in portfolio composition. Net loan charge-offs increased $5 million 
to $22 million, or 0.04 percent of average total loans for the year ended December 31, 2023, compared to $17 million, or 0.03 
percent  of  average  total  loans  for  the  year  ended  December  31,  2022,  with  net  charge-offs  in  Corporate  Banking,  Business 
Banking and Technology and Life Sciences partially offset by net recoveries in general Middle Market. The provision for credit 
losses  on  lending-related  commitments  was  a  benefit  of  $11  million  for  the  year  ended  December  31,  2023,  compared  to  an 
expense of $21 million for the year ended December 31, 2022.

An analysis of the allowance for credit losses and a summary of nonperforming assets are presented under the "Credit 
Risk" subheading in the "Risk Management" section of this financial review. For information regarding methodology used in 
the determination of allowance for credit losses, refer to Note 1 to the consolidated financial statements.

(b) Effective January 1, 2023, the Corporation reported derivative income, syndication agent fees (previously a component of commercial 
lending fees) and investment banking fees (previously a component of other noninterest income) as a combined item captioned by capital 
markets  income  on  the  Consolidated  Statements  of  Income.  Beginning  with  fourth  quarter  2023,  risk  management  hedging  income 
(previously a component of other noninterest income) was presented as a separate item on the Consolidated Statements of Income. Prior 
periods have been adjusted to conform to this presentation, and the changes do not impact total noninterest income.

(c) The table below provides further details on certain categories included in other noninterest income.

Noninterest income increased $10 million to $1.1 billion, reflecting increases in other noninterest income, brokerage 
fees,  card  fees,  commercial  lending  fees  and  letter  of  credit  fees,  partially  offset  by  decreases  in  risk  management  hedging 
income,  service  charges  on  deposit  accounts  and  capital  markets  income.  Other  noninterest  income  included  increases  in 
deferred compensation asset returns (offset in noninterest expenses) and FHLB stock dividends. 

Brokerage fees are commissions earned for facilitating securities transactions for customers as well as other brokerage 
services provided. In November 2023, the Corporation transitioned support of its retail brokerage business, including specific 
insurance, brokerage and investment advisory activities previously conducted by the Corporation's broker-dealer subsidiary, to 
Ameriprise Financial Institutions Group, an independent financial services broker. Since this transition, brokerage fees include 
income from sales of select investment products of an independent financial services broker, net of commissions passed through 
to  employees  licensed  by  the  independent  broker  to  sell  their  products.  Brokerage  fees  increased  $9  million,  or  47  percent, 
reflecting the impact of the Corporation's new investment program partner as well as increased money market funds revenue 
related to higher short-term rates as well as elevated transactional revenue for personal trusts. 

Card fees consist primarily of interchange and other fee income earned on government prepaid card, commercial card, 
debit/Automated Teller Machine (ATM) card and merchant payment processing services. Card fees increased $7 million, or 2 
percent, reflecting higher processing volumes in merchant services and ATM network bonuses, partially offset by a one-time 
government card vendor incentive received in 2022.

Commercial lending fees include fees assessed on the unused portion of lines of credit (unused commitment fees) and 
loan  servicing  fees.  These  fees  increased  $4  million,  or  6  percent,  driven  by  higher  commitment  fees  from  growth  in  loan 

F-6

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
commitments, partially offset by a decrease in Mortgage Banker Finance service charges due to the mostly completed planned 
exit from this line of business.

Letter of credit fees increased $4 million, or 11 percent, reflecting an increase in standby letters of credit activity.

Risk management hedging income declined $50 million, resulting from a $91 million net loss related to Bloomberg 
Short-Term  Bank  Yield  Index  (BSBY)  cessation,  which  was  partially  offset  by  a  $41  million  increase  in  price  alignment 
income  received  on  collateral  posted  for  centrally  cleared  risk  management  positions.  Refer  to  the  "BSBY  Cessation" 
subheading in the "Market and Liquidity Risk" section of this financial review, as well as Note 8 to the consolidated financial 
statements, for further discussion of de-designated interest rate hedges.

Service  charges  on  deposit  accounts  consist  primarily  of  charges  on  retail  and  business  accounts,  including  fees  for 
treasury management services. Service charges on deposit accounts decreased $10 million, or 5 percent, reflecting declines in 
volume-based  deposit  fees  and  the  elimination  of  certain  consumer  account  fees  as  well  as  an  increase  in  earnings  credit 
allowances provided to customers that reduced their service charges.

Capital markets income consists of net gains and losses recognized on customer-initiated derivative instruments, net of 
the  impact  of offsetting positions, syndication agent  fees,  investment  banking fees and  merger and  acquisition  advisory fees. 
Capital  markets  income  decreased  $7  million,  or  5  percent,  primarily  due  to  unfavorable  credit  valuation  adjustments,  lower 
interest rate and energy derivative income and a decline in syndication agent fees, partially offset by increases in advisory fees 
and foreign exchange derivative income.

Other noninterest income increased $52 million, as detailed below, driven by increases in deferred compensation asset 
returns (offset in noninterest expenses) and FHLB stock dividends due to higher rates and additional stock acquired during the 
year.

Noninterest  expenses  increased  $361  million  to  $2.4  billion,  primarily  due  to  increases  in  FDIC  insurance  expense, 

salaries and benefits expense, other noninterest expenses, outside processing fee expenses and software expense.

FDIC insurance expense increased $149 million, reflecting $109 million in additional expense resulting from the FDIC 
Board of Directors' November 2023 approval of a special assessment to recover the loss to the Deposit Insurance Fund (DIF) 
following the failures of Silicon Valley Bank and Signature Bank. In February 2024, the FDIC indicated that it now expects a 
larger loss to the DIF than originally estimated and that it plans to provide institutions with an updated estimate of their total 
special  assessment  amount  with  its  first  quarter  2024  special  assessment  invoice,  to  be  released  in  June  2024.  This  updated 
special assessment total may result in additional FDIC expense to be recorded later this year.

Salaries and benefits expense increased $98 million, or 8 percent, reflecting increases from annual merit increases and 
staff additions, temporary labor and deferred compensation expense (offset in other noninterest income), partially offset by a 
decrease in incentive compensation.

Other  noninterest  expenses  increased  $80  million,  or  95  percent,  including  increases  in  non-salary  pension  expense, 
litigation and regulatory-related expenses, consulting fees and legal fees, partially offset by a net gain on fixed asset disposals, 
which included gains on real estate and asset impairments.

Outside processing fee expense increased $26 million, or 10 percent, reflecting an increase in state program costs and 
data  processing  conversion  costs,  partially  offset  by  lower  card  fulfillment  fees  and  a  decline  in  volume  of  government  card 
transactions tied to card fee revenues.

Software  expenses  increased  $10  million,  or  6  percent,  driven  by  higher  cloud  computing  costs  and  an  increase  in 

rental and maintenance fees. 

The  above  detail  includes  expenses  for  certain  modernization  initiatives  related  to  the  transformation  of  the  retail 
banking  delivery  model,  alignment  of  corporate  facilities  and  optimization  of  technology  platforms.  Modernization-related 
expenses totaled $6 million during 2023, compared to $38 million during 2022, and were comprised of transitional real estate 
costs (reported in occupancy expense), severance and contract labor (reported in salaries and benefits expense) as well as gains 
on  sale  of  real  estate  assets,  asset  impairments  and  contract  termination  costs  (reported  in  other  noninterest  expenses).  The 
above  detail  also  includes  $25  million  of  severance  costs  during  2023  related  to  expense  recalibration  initiatives  intended  to 
enhance earnings power and create capacity for strategic and risk management initiatives.

Income Taxes and Related Items

The provision for income taxes was $263 million in 2023, compared to $325 million in 2022. Net deferred tax assets 
were $1.0 billion at December 31, 2023, compared to $1.1 billion at December 31, 2022. Refer to Note 18 to the consolidated 
financial statements for information about the components of net deferred tax assets. Deferred tax assets of $1.3 billion were 
evaluated  for  realization  and  it  was  determined  that  a  valuation  allowance  of  $6  million  for  federal  foreign  tax  credits  and 
certain  state  net  operating  loss  (NOL)  carryforwards  was  needed  at  December  31,  2023.  For  further  information  on  the 
Corporation’s valuation policy for deferred tax assets, refer to Note 1 of the consolidated financial statements.

STRATEGIC LINES OF BUSINESS

The Corporation has strategically aligned its operations into three major business segments: the Commercial Bank, the 
Retail Bank and Wealth Management. These business segments are differentiated based on the type of customer and the related 
products  and  services  provided.  In  addition  to  the  three  major  business  segments,  the  Finance  Division  is  also  reported  as  a 
segment.  The  Other  category  includes  items  not  directly  associated  with  the  business  segments  or  the  Finance  segment.  The 
performance  of  the  business  segments  is  not  comparable  with  the  Corporation's  consolidated  results  and  is  not  necessarily 
comparable  with  similar  information  for  any  other  financial  institution.  Additionally,  because  of  the  interrelationships  of  the 
various  segments,  the  information  presented  is  not  indicative  of  how  the  segments  would  perform  if  they  operated  as 
independent  entities.  Note  22  to  the  consolidated  financial  statements  describes  the  Corporation's  segment  reporting 
methodology as well as the business activities of each business segment and presents financial results of the business segments 
for the years ended December 31, 2023, 2022 and 2021.

The Corporation's management accounting system assigns balance sheet and income statement items to each segment 
using  certain  methodologies,  which  are  regularly  reviewed  and  refined.  These  methodologies  may  be  modified  as  the 
management accounting system is enhanced and changes occur in the organizational structure and/or product lines.

Net interest income for each segment reflects the interest income generated by earning assets less interest expense on 
interest-bearing liabilities plus the net impact from associated internal funds transfer pricing (FTP) funding credits and charges. 
The FTP methodology allocates credits to each business segment for deposits and other funds provided as well as charges for 
loans  and  other  assets  being  funded.  FTP  crediting  rates  on  deposits  and  other  funds  provided  reflect  the  long-term  value  of 
deposits and other funding sources based on their implied maturities. Due to the longer-term nature of implied maturities, FTP 
crediting  rates  are  generally  less  volatile  than  changes  in  interest  rates  observed  in  the  market.  FTP  charge  rates  for  funding 
loans and other assets reflect a matched cost of funds based on the pricing and duration characteristics of the assets. As a result 
of applying matched funding, interest revenue for each segment resulting from loans and other assets is generally not impacted 
by changes in interest rates. Therefore, net interest income for each segment primarily reflects the volume of loans and other 
earning assets at the spread over the matched cost of funds, as well as the volume of deposits at the associated FTP crediting 
rates. Generally, in periods of rising interest rates, FTP charge rates for funding loans and FTP crediting rates on deposits will 
increase, with FTP crediting rates for deposits typically repricing at a slower pace than FTP charge rates for funding loans.

The following table presents net income (loss) by business segment.

Average  loans  increased  $3.0  billion  and  included  increases  in  Commercial  Real  Estate,  National  Dealer  Services, 
Corporate Banking and Environmental Services, partially offset by decreases in Mortgage Banker Finance related to planned 
exit  from  this  business  and  Equity  Fund  Services.  Average  deposits  decreased  $9.6  billion,  with  declines  in  all  deposit 
categories reflecting customer diversification efforts following the banking industry disruption in the first quarter of 2023. This 
decline  was  primarily  driven  by  decreases  in  noninterest-bearing  and  money  market  deposits,  with  the  largest  declines  in 
general  Middle  Market,  Technology  and  Life  Sciences,  Business  Banking,  Commercial  Real  Estate,  Corporate  Banking  and 
National Dealer Services.

The Commercial Bank's net income increased $59 million to $1.1 billion. Net interest income increased $290 million 
due to increased loan income as well as higher FTP crediting rates on deposits related to the increase in short-term interest rates, 
partially  offset  by  higher  allocated  net  FTP  charges.  The  provision  for  credit  losses  increased  $58  million  to  $90  million, 
reflecting  loan  growth,  an  uncertain  economic  outlook  and  credit  migration.  Net  credit-related  charge-offs  were  $20  million, 
relatively stable compared to the prior year, with net charge-offs in Corporate Banking, Business Banking and Technology and 
Life Sciences partially offset by net recoveries in general Middle Market. Noninterest income decreased $4 million, primarily 
due  to  lower  capital  markets  income  and  service  charges  on  deposit  accounts,  partially  offset  by  higher  securities  trading 
income  and  commercial  lending  fees.  Noninterest  expenses  increased  $142  million,  primarily  reflecting  increases  in  FDIC 
insurance expense (related to special assessment), salaries and benefits expense and outside processing fee expense.

categories with the exception of time deposits. The Retail Bank's net income increased $97 million to $176 million. Net interest 
income  increased  $166  million  to  $846  million,  primarily  due  to  higher  FTP  crediting  rates  on  deposits.  Noninterest  income 
was relatively stable, while noninterest expenses increased $38 million, primarily due to increases in FDIC insurance expense 
(related to special assessment), partially offset by decreases in occupancy and consulting expenses.

Net interest income increased $9 million to $208 million, primarily due to higher loan income, partially offset by an increase in 
allocated net FTP charges. Noninterest income increased $9 million to $307 million, primarily driven by investment fees, while 
noninterest expenses increased $54 million, reflecting increases in salaries and benefits expense, consulting expenses, outside 
processing fee expense and FDIC insurance expense (related to special assessment).

Average  deposits,  which  primarily  consist  of  centrally-managed  brokered  time  deposits  fully  insured  by  the  FDIC, 
increased $3.7 billion. Net loss for the Finance and Other category increased $410 million to $501 million. Net interest expense 
increased $417 million to $591 million, reflecting the impact of interest rate swaps (which are centrally managed) as well as 
increased balances from higher-cost funding sources. Noninterest income increased $8 million to $49 million, primarily due to 
higher investment fees and FHLB stock dividends, partially offset by a decrease in risk management hedging income (BSBY 
cessation).  Noninterest  expenses  increased  $127  million,  reflecting  higher  salaries  and  benefits  expense  and  FDIC  insurance 
expense (special assessment), partially offset by gains on the sale of real estate.

Average total loans increased $3.4 billion to $53.9 billion in 2023, compared to $50.5 billion in 2022, which included 
a $2.2 billion increase in Commercial Real Estate, which generally serves real estate developers and investors. National Dealer 
Services,  which  provides  floor  plan  inventory  financing  and  commercial  mortgages  to  auto  dealerships,  increased  by 
$1.1 billion, while Corporate Banking, which serves companies with revenues generally over $500 million, increased by $516 
million.  These  increases  were  partially  offset  by  a  $634  million  decline  in  Mortgage  Banker  Finance  due  to  the  mostly 
completed planned exit from this line of business.

On a period-end basis, investment securities were $16.9 billion at December 31, 2023, a decrease of $2.1 billion from 
$19.0  billion  at  December  31,  2022,  due  to  maturities  of  Treasury  securities  and  paydowns  of  mortgage-backed  securities, 
partially offset by an improvement in unrealized losses, from $3.0 billion at December 31, 2022 to $2.7 billion at December 31, 
2023. At December 31, 2023, the effective duration of the Corporation's securities portfolio was approximately 5.5 years. On an 
average basis, investment securities decreased $1.6 billion to $17.4 billion in 2023, compared to $19.0 billion in 2022, primarily 
due to unrealized losses and maturities of Treasury securities.

Interest-Bearing Deposits with Banks and Other Short-Term Investments

  Interest-bearing  deposits  with  banks,  which  are  mostly  used  to  manage  liquidity  requirements  of  the  Corporation, 
primarily include deposits with the Federal Reserve Bank (FRB) and also include deposits with banks in developed countries or 
international banking facilities of foreign banks located in the United States. On a period-end basis, interest-bearing deposits 
with  banks  increased  $3.5  billion  to  $8.1  billion  at  December  31,  2023.  On  an  average  basis,  interest-bearing  deposits  with 
banks decreased $1.8 billion to $7.5 billion in 2023. 

Other short-term investments include federal funds sold, trading securities, money market investments and loans held-
for-sale.  Substantially  all  trading  securities  are  deferred  compensation  plan  assets.  Loans  held-for-sale  include  variable-rate 
demand notes for which the Corporation has purchased the underlying bonds as well as residential mortgage loans originated 
with management's intention to sell and, from time to time, other loans that are transferred to held-for-sale. On a period-end 
basis,  other  short-term  investments  increased  $242  million  to  $399  million  at  December  31,  2023,  which  was  driven  by  the 
above-referenced variable-rate demand notes. On an average basis, other short-term investments increased $165 million to $339 
million in 2023.

On a period-end basis, total deposits decreased $4.6 billion to $66.8 billion at December 31, 2023, compared to $71.4 
billion at December 31, 2022, reflecting a decrease of $12.1 billion in noninterest-bearing deposits, partially offset by a $7.5 
billion increase in interest-bearing deposits.

Uninsured deposits are defined as the portion of deposit accounts in U.S. offices that exceed the FDIC insurance limit 
and  amounts  in  any  other  uninsured  investment  or  deposit  account  that  are  classified  as  deposits  and  are  not  subject  to  any 
federal or state deposit insurance regimes. Total uninsured deposits were $31.5 billion and $45.5 billion at December 31, 2023 
and  2022,  respectively,  as  calculated  per  regulatory  guidance.  The  portion  of  domestic  time  deposits  in  excess  of  insurance 
limits was $797 million  and $370 million at December 31, 2023  and 2022,  respectively.  Time deposits  otherwise uninsured, 
which consist of foreign office time deposits and all mature in three months or less, totaled $13 million at December 31, 2023, 
compared to $51 million at December 31, 2022. 

On a period-end basis, short-term borrowings totaled $3.6 billion at December 31, 2023, compared to $3.2 billion at 
December 31, 2022, and included federal funds purchased and short-term Federal Home Loan Bank (FHLB) advances. On a 
period-end basis, total medium- and long-term debt totaled $6.2 billion at December 31, 2023, an increase of $3.2 billion from 
$3.0 billion at December 31, 2022. The Corporation uses medium- and long-term debt, which includes medium- and long-term 
senior notes, subordinated notes and FHLB advances, to provide funding for earning assets, liquidity and regulatory capital.

Average  deposits  decreased  $9.5  billion  to  $66.0  billion  in  2023,  compared  to  $75.5  billion  in  2022,  reflecting  an 
$11.1 billion decrease in noninterest-bearing deposits, partially offset by a $1.7 billion increase in interest-bearing deposits. The 
decline  in  noninterest-bearing  deposits  reflected  customer  diversification  efforts  following  the  banking  industry  disruption  in 
the first quarter of 2023 as well as a shift in deposit mix from noninterest-bearing to interest-bearing due to the current higher 
interest  rate  environment,  while  the  increase  in  interest-bearing  deposits  was  primarily  due  to  increases  in  brokered  time 
deposits and customer certificates of deposit. 

Average short-term borrowings increased by $6.8 billion to $7.2 billion in 2023, compared to $436 million in 2022, 
while  average  medium-  and  long-term  debt  increased  $3.0  billion  to  $5.8  billion  in  2023,  compared  to  $2.8  billion  in  2022, 
primarily driven by FHLB advances, partially offset by $850 million in senior notes that matured in the third quarter of 2023. 
Further information on medium- and long-term debt is provided in Note 12 to the consolidated financial statements.

Since the inception of the Corporation's share repurchase program in 2010, a total of 97.2 million shares have been 
authorized for repurchase. There is no expiration date for the share repurchase program. Management is not currently engaged 
in  repurchasing  shares  and  will  continue  to  monitor  various  factors,  including  the  Corporation's  earnings  generation,  capital 
needs to fund future loan growth, regulatory changes and market conditions, before resuming the share repurchase program.

The Corporation continues to target a Common Equity Tier 1 (CET1) capital ratio of approximately 10 percent with 
active capital management. At December 31, 2023, the Corporation's CET1 capital ratio was 11.09 percent, a increase of 109 
basis points compared to December 31, 2022. 

The Corporation is subject to the capital adequacy standards under the Basel III regulatory framework (Basel III). This 
regulatory  framework  establishes  comprehensive  methodologies  for  calculating  regulatory  capital  and  risk-weighted  assets 
(RWA). Basel III also set minimum capital ratios as well as overall capital adequacy standards.

Under Basel III, regulatory capital comprises CET1 capital, additional Tier 1 capital and Tier 2 capital. CET1 capital 
predominantly includes common shareholders' equity, less certain deductions for goodwill, intangible assets and deferred tax 
assets  that  arise  from  net  operating  losses  and  tax  credit  carry-forwards.  Additionally,  the  Corporation  has  elected  to 
permanently exclude capital in accumulated other comprehensive income (AOCI) related to debt classified as available-for-sale 
as  well  as  for  cash  flow  hedges  and  defined  benefit  postretirement  plans  from  CET1,  an  option  available  to  standardized 
approach entities under Basel III. Tier 1 capital incrementally includes noncumulative perpetual preferred stock. Tier 2 capital 
includes Tier 1 capital as well as subordinated debt qualifying as Tier 2 and qualifying allowance for credit losses.

The  Corporation  computes  RWA  using  the  standardized  approach.  Under  the  standardized  approach,  RWA  is 
generally  based  on  supervisory  risk-weightings  which  vary  by  counterparty  type  and  asset  class.  Under  the  Basel  III 
standardized  approach,  capital  is  required  for  credit  risk  RWA,  to  cover  the  risk  of  unexpected  losses  due  to  failure  of  a 
customer  or  counterparty  to  meet  its  financial  obligations  in  accordance  with  contractual  terms;  and  if  trading  assets  and 
liabilities  exceed  certain  thresholds,  capital  is  also  required  for  market  risk  RWA,  to  cover  the  risk  of  losses  due  to  adverse 
market movements or from position-specific factors.

In addition to the minimum risk-based capital requirements, the Corporation is required to maintain a minimum capital conservation 
buffer, in the form of common equity tier 1 capital, in order to avoid restrictions on capital distributions and discretionary bonuses. 

The Corporation's capital ratios exceeded minimum regulatory requirements as follows:

At December 31, 2023, the Corporation and its U.S. banking subsidiaries exceeded the capital ratios required for an 
institution  to  be  considered  “well  capitalized”  by  the  standards  developed  under  the  Federal  Deposit  Insurance  Corporation 
Improvement Act of 1991. Refer to Note 20 to the consolidated financial statements for further discussion of regulatory capital 
requirements, capital ratio calculations and restrictions on the ability of the Corporation's banking subsidiaries to transfer assets 
to the Corporation.

The common shareholders' equity ratio increased 140 basis points to 7.00 percent at December 31, 2023, primarily due 
to  lower  unrealized  losses  on  investment  securities  available-for-sale  and  the  Corporation's  cash  flow  hedge  portfolio.  The 
unrealized losses in the Corporation's available-for-sale investment security portfolio, which are due to market valuations since 
the time of initial acquisition, are not expected to be realized. The tangible common equity ratio, which excludes goodwill and 
other intangible assets, increased 141 basis points to 6.30 percent for the same reasons discussed above. Common shareholders' 
equity included $3.0 billion in accumulated other comprehensive losses, with approximately $2.3 billion of those losses relating 
to balances recorded in total assets, comprised of valuation adjustments to available-for-sale securities and pension assets, as 
well  as  related  deferred  tax  assets.  These  amounts  impacted  the  common  shareholders'  equity  ratio  by  328  basis  points;  the 
impact on the tangible common equity ratio using the same calculation method was 332 basis points. 

Basel III Endgame Framework

On July 27, 2023, the federal banking agencies issued a notice of proposed rulemaking, commonly referred to as Basel 
III  Endgame  (the  Capital  Proposal)  that  would  significantly  increase  the  capital  requirements  applicable  to  large  banking 
organizations with total assets of $100 billion or more. The Capital Proposal would align the regulatory capital calculation and 
the calculation of risk-weighted assets across large banking organizations subject to the Capital Proposal and require Category 
III and IV banking organizations to include most components of AOCI, including net unrealized gains and losses on available-
for-sale securities, in their regulatory capital ratios. The Capital Proposal is subject to a public comment period, which ended on 
January  16,  2024,  and,  if  adopted,  would  include  a  three-year  transition  period  beginning  July  1,  2025.  As  of  December  31, 
2023, the Corporation had total assets of $85.8 billion. While the Capital Proposal would not apply to the Corporation as it is 
currently  proposed,  if  the  Corporation  becomes  subject  to  the  requirements  of  the  Capital  Proposal  in  the  future  or  becomes 
subject to any other new laws or regulations related to capital and liquidity, such requirements could limit the Corporation’s 
ability  to  pay  dividends  or  make  share  repurchases  or  require  Comerica  to  reduce  business  levels  or  to  raise  capital,  which 
would have a material adverse effect on the Corporation’s financial condition and results of operations. If subject to the Capital 
Proposal, the estimated impact related to proposed inclusion of most components of AOCI would be an approximate 300 basis 
point decrease to common equity tier-1 capital based on December 31, 2023 financials.

RISK MANAGEMENT

The  Corporation  assumes  various  types  of  risk  as  a  result  of  conducting  business  in  the  normal  course.  The 
Corporation's enterprise risk management framework provides a process for identifying, measuring, controlling and managing 
these  risks.  This  framework  incorporates  a  risk  assessment  process,  a  collection  of  risk  committees  that  manage  the 
Corporation's  major  risk  elements  and  a  risk  appetite  statement  that  outlines  the  levels  and  types  of  risks  the  Corporation 
accepts.  The  Corporation  continuously  enhances  its  enterprise  risk  framework  with  additional  processes,  tools  and  systems 
designed to not only provide management with deeper insight into the various existing and emerging risks in accordance with 
its appetite for risk, but also to improve the Corporation's ability to control those risks and ensure that appropriate consideration 
is received for the risks taken.

The Corporation’s front line employees, the first line of defense, are responsible for the day-to-day management and 
ownership  of  risks,  including  the  identification,  assessment,  measurement  and  control  of  risks  encountered  as  a  part  of  the 
normal course of business. Each of the major risk categories are further monitored and measured by specialized risk managers 
in the second line of defense within the Enterprise Risk Division, who provide oversight as well as independent and effective 
challenge and guidance for the risk management activities of the organization. The Enterprise Risk Division, led by the Chief 
Risk Officer, is responsible for designing and managing the Corporation’s enterprise risk management framework and ensures 
effective  risk  management  oversight.  Risk  management  committees  serve  as  a  point  of  review  and  escalation  for  those  risks 
which may have risk interdependencies or where risk levels may be nearing the limits outlined in the Corporation’s risk appetite 
statement. These committees comprise senior and executive management that represent views from both the lines of business 
and  risk  management.  Internal  Audit,  the  third  line  of  defense,  monitors  and  assesses  the  overall  effectiveness  of  the  risk 
management framework on an ongoing basis and provides an independent, objective assessment of the Corporation’s ability to 
manage and control risk to management and the Audit Committee of the Board.

The Enterprise Risk and Return Committee, chaired by the Chief Risk Officer, is established by the Enterprise Risk 
Committee of the Board and responsible for governance over the risk management framework, providing oversight in managing 
the Corporation's aggregate risk position and reporting on the comprehensive portfolio of risks as well as the potential impact 
these risks can have on the Corporation's risk profile and resulting capital level. Capital provides the primary buffer for risk and 
also serves as a measuring tool when evaluating risk. The Enterprise Risk and Return Committee is principally composed of 
senior officers and executives representing the different risk areas and business units who are appointed by the Chairman and 
Chief Executive Officer of the Corporation.

The  Board's  Enterprise  Risk  Committee  meets  quarterly  and  is  chartered  to  assist  the  Board  in  promoting  the  best 
interests of the Corporation by overseeing policies and risk practices relating to enterprise-wide risk and ensuring compliance 
with bank regulatory obligations. Members of the Enterprise Risk Committee are selected such that the committee comprises 
individuals whose experiences and qualifications can lead to broad and informed views on risk matters facing the Corporation 
and the financial services industry. These include, but are not limited to, existing and emerging risk matters related to credit, 
market, liquidity, operational, technology, compliance and strategic conditions. A comprehensive risk report is submitted to the 
Enterprise Risk Committee each quarter providing management's view of the Corporation's aggregate risk position.

Further  discussion  and  analyses  of  each  major  risk  area  are  included  in  the  following  sub-sections  of  the  Risk 

Management section in this financial review.

Credit Risk

Credit risk represents the risk of loss due to failure of a customer or counterparty to meet its financial obligations in 
accordance  with  contractual  terms.  Credit  risk  is  found  in  all  activities  where  success  depends  on  counterparty,  issuer  or 
borrower performance. It arises any time funds are extended, committed, invested or otherwise exposed, whether reflected on or 
off the balance sheet. The governance structure is administered through the Strategic Credit Committee. The Strategic Credit 
Committee is chaired by the Chief Credit Officer and approves recommendations to address credit risk matters through credit 
policy,  credit  risk  management  practices  and  required  credit  risk  actions.  The  Strategic  Credit  Committee  also  ensures  a 
comprehensive reporting of credit risk levels and trends, including exception levels, along with identification and mitigation of 
emerging risks. In order to facilitate the corporate credit risk management process, various other corporate functions provide the 
resources  for  the  Strategic  Credit  Committee  to  carry  out  its  responsibilities.  The  Corporation  manages  credit  risk  through 
underwriting and periodically reviewing and approving its credit exposures in accordance with established credit policies and 
guidelines.  Additionally,  the  Corporation  manages  credit  risk  through  loan  portfolio  diversification,  limiting  exposure  to  any 
single  industry,  customer  or  guarantor,  and  selling  participations  and/or  syndicating  credit  exposures  above  those  levels  it 
deems prudent to third parties.

The  Credit  Division  manages  credit  policy  and  provides  the  resources  to  manage  the  line  of  business  transactional 
credit risk, assuring that all exposure is risk rated according to the requirements of the credit risk rating policy and providing 

F-18

business  segment  reporting  support  as  necessary.  The  Enterprise  Risk  Division  provides  credible  and  well-documented 
challenge of overall portfolio credit risk, and other credit-related attributes of the Corporation's loan portfolios, with a particular 
emphasis on all attendant modeled results. The Corporation's Asset Quality Review function, a division of Internal Audit, audits 
the accuracy of internal risk ratings that are assigned by the lending and credit groups. The Special Assets Group is responsible 
for managing the recovery process on distressed or defaulted loans and loan sales.

Credit  Analytics  and  Strategy,  within  the  Credit  Division,  provides  comprehensive  reporting  on  portfolio  credit  risk 
levels and trends, continuous assessment and verification of risk rating models, quarterly calculation of the allowance for loan 
losses and the allowance for credit losses on lending-related commitments and calculations of both expected and unexpected 
loss.

Allowance for Credit Losses

The  allowance  for  credit  losses  includes  both  the  allowance  for  loan  losses  and  the  allowance  for  credit  losses  on 
lending-related  commitments.  The  allowance  for  credit  losses  increased  by  $67  million  from  $661  million  at  December  31, 
2022 to $728 million at December 31, 2023, reflecting an uncertain economic outlook and credit migration, as well as changes 
in portfolio composition.

The following table presents metrics of the allowance for credit losses and nonperforming loans.

The economic forecasts informing the current expected credit loss (CECL) model reflect the cumulative effects of the 
Federal  Reserve  Bank's  tight  monetary  policy  that  are  weighing  on  the  real  economy,  as  well  as  several  years  of  elevated 
inflation  that  have  largely  depleted  excess  savings  that  households  accumulated  during  the  pandemic.  Energy  prices  are 
projected to level off amid crosswinds from the Russia-Ukraine conflict, rising U.S. crude production and weak demand from 
China and other major foreign economies. Residential and commercial real estate property prices face headwinds from the long 
and variable lags by which the Federal Reserve Bank's tighter monetary policy affect real asset prices.

Downside  risks  to  growth  from  geopolitical  risks,  a  potential  government  shutdown,  the  restart  of  student  loan 
payments and less expansionary fiscal policy are projected to collectively contribute to slower growth in 2024. Price pressures 
are  forecasted  to  gradually  return  to  pre-pandemic  norms  as  a  modest  margin  of  slack  opens  in  the  economy's  productive 
capacity. The Federal Reserve Bank's aggressive tightening of monetary policy, including rapid increases in interest rates and 
reductions in the size of its balance sheet, contribute to elevated risk of a policy error or recession.

These factors shaped the 2-year reasonable and supportable forecast used by the Corporation in its CECL estimate at 
December 31, 2023. The U.S. economy is projected to grow at a below-trend rate through 2024 before gradually normalizing to 
its trend growth rate. Certain economic variables, like oil prices, are expected to increase in the short term before decreasing as 
inflation normalizes. Forecasts for other key economic variables are generally consistent with those of Gross Domestic Product 
(GDP),  while  interest  rate  forecasts  reflect  market  expectations  and  recent  guidance  from  the  Federal  Reserve  Bank.  The 
following table summarizes select economic variables representative of the economic forecasts used to develop the allowance 
for credit losses estimate at December 31, 2023.

Gradual  growth  to  a  peak  near  3  percent  in  second  quarter  2025 
before returning to a growth rate of around 2 percent.

Remains near 4 percent throughout the forecast period.

Spreads  widen  to  2.4  percent  by  third  quarter  2024  before 
normalizing to 2 percent by the end of the forecast period.

Prices  increase  from  current  levels  to  $84  dollars  in  first  quarter 
2024 before declining to $76 by the end of the forecast period. 

  Due  to  the  high  degree  of  uncertainty  regarding  recessionary  pressures,  persistent  inflation,  continued  high  interest 
rates  and  other  tail  risks  to  the  outlook,  management  considered  other  economic  scenarios  to  make  appropriate  qualitative 
adjustments for certain sectors of its lending portfolio, including more benign as well as more severe scenarios.

F-19

Refer to Note 1 to the consolidated financial statements for a discussion of the methodology used in the determination 

of the allowance for credit losses.

Allowance for Loan Losses

The allowance for loan losses represents management’s estimates of current expected credit losses in the Corporation’s 
loan  portfolio.  The  allowance  for  loan  losses  increased  $78  million  to  $688  million  at  December  31,  2023,  compared  to 
$610 million at December 31, 2022.

Collective  loss  estimates  are  determined  by  applying  reserve  factors,  designed  to  estimate  current  expected  credit 
losses, to amortized cost balances over the remaining contractual life of the collectively evaluated portfolio. Loans with similar 
risk characteristics are aggregated into homogeneous pools. The allowance for loan losses also includes qualitative adjustments 
to  bring  the  allowance  to  the  level  management  believes  is  appropriate  based  on  factors  that  have  not  otherwise  been  fully 
accounted for, including adjustments for foresight risk, input imprecisions and model imprecision. Credit losses for loans that 
no longer share risk characteristics with the loan pools are estimated on an individual basis. Individual credit loss estimates are 
typically  performed  for  nonaccrual  loans  and  are  based  on  one  of  several  methods,  including  the  estimated  fair  value  of  the 
underlying collateral, observable market value of similar debt or the present value of expected cash flows. 

Allowance for Credit Losses on Lending-Related Commitments

The allowance for credit losses on lending-related commitments estimates current expected credit losses on collective 
pools of letters of credit and unused commitments to extend credit based on reserve factors, determined in a manner similar to 
business  loans,  multiplied  by  a  probability  of  draw  estimate  based  on  historical  experience  and  credit  risk,  applied  to 
commitment amounts. The allowance for credit losses on lending-related commitments totaled $40 million and $51 million at 
December 31, 2023 and December 31, 2022, respectively.

Nonperforming Assets

Nonperforming  assets  include  loans  on  nonaccrual  status  and  foreclosed  assets.  Effective  January  1,  2023,  the 
Corporation  prospectively  adopted  the  provisions  of  Accounting  Standards  Update  No.  2022-02,  "Financial  Instruments  - 
Credit Losses (Topic 326): Troubled Debt Restructuring and Vintage Disclosures", which eliminated the accounting for TDRs. 
Refer  to  Note  1  to  the  consolidated  financial  statements  for  further  information.  At  December  31,  2022,  reduced-rate  loans 
represented TDRs which had been renegotiated to less than their original contractual rates.

personal purpose nonaccrual loans and net charge-offs.

Loans past due 90 days or more and still accruing interest generally represent loans that are well-collateralized and in 
the process of collection. Loans past due 90 days or more decreased $3 million to $20 million at December 31, 2023, compared 
to $23 million at December 31, 2022. Loans past due 30-89 days decreased $180 million to $198 million at December 31, 2023, 
compared to $378 million at December 31, 2022. Loans past due 30 days or more and still accruing interest as a percentage of 
total loans were 0.42 percent and 0.75 percent at December 31, 2023 and December 31, 2022, respectively. An aging analysis 
of loans included in Note 4 to the consolidated financial statements provides further information about the balances comprising 
past due loans.

The following table presents a summary of total criticized loans. The Corporation's criticized list is consistent with the 
Special Mention, Substandard and Doubtful categories defined by regulatory authorities. Criticized loans on nonaccrual status 
are individually subjected to quarterly credit quality reviews, and the Corporation may establish specific allowances for such 
loans. A table of loans by credit quality indicator included in Note 4 to the consolidated financial statements provides further 
information about the balances comprising total criticized loans.

Concentrations of Credit Risk

Concentrations of credit risk may exist when a number of borrowers are engaged in similar activities, or activities in 
the  same  geographic  region,  and  have  similar  economic  characteristics  that  would  cause  them  to  be  similarly  impacted  by 
changes in economic or other conditions. The Corporation has concentrations of credit risk with the commercial real estate and 
automotive  industries.  All  other  industry  concentrations,  as  defined  by  management,  individually  represented  less  than  10 
percent of total loans at December 31, 2023.

The Corporation limits risk inherent in its commercial real estate lending activities by monitoring borrowers directly 
involved  in  the  commercial  real  estate  markets  and  adhering  to  conservative  policies  on  loan-to-value  ratios  for  such  loans. 
Commercial  real  estate  loans,  consisting  of  real  estate  construction  and  commercial  mortgage  loans,  totaled  $18.8  billion  at 
December  31,  2023.  Commercial  real  estate  loans  made  to  borrowers  in  the  Commercial  Real  Estate  business  line,  which 
includes loans to real estate developers, totaled $9.3 billion, or 50 percent of total commercial real estate loans, an increase of

predominantly  secured  by  multi-family  and  industrial  properties,  comprising  46  percent  and  34  percent  of  the  portfolio, 
respectively, with only 6 percent secured by office properties. Commercial real estate loans in other business lines totaled $9.5 
billion,  or  50  percent  of  total  commercial  real  estate  loans,  at  December  31,  2023,  an  increase  of  $247  million  compared  to 
December  31,  2022.  These  loans  consisted  primarily  of  owner-occupied  commercial  mortgages,  which  bear  credit 
characteristics  similar  to  non-commercial  real  estate  business  loans.  Generally,  loans  previously  reported  as  real  estate 
construction are classified as commercial mortgage loans upon receipt of a certificate of occupancy.

The real estate construction loan portfolio primarily contains loans made to long-tenured customers with satisfactory 
completion experience. Criticized real estate construction loans in the Commercial Real Estate business line totaled $86 million 
at December 31, 2023 compared to none at December 31, 2022. In other business lines, criticized real estate construction loans 
totaled  $12  million  at  December  31,  2023,  compared  to  $3  million  at  December  31,  2022.  There  were  no  real  estate 
construction loan net charge-offs in the years ended December 31, 2023 and 2022.

Commercial  mortgage  loans  are  loans  where  the  primary  collateral  is  a  lien  on  any  real  property  and  are  primarily 
loans  secured  by  owner-occupied  real  estate.  Real  property  is  generally  considered  primary  collateral  if  the  value  of  that 
collateral  represents  more  than  50  percent  of  the  commitment  at  loan  approval.  Loans  in  the  commercial  mortgage  portfolio 
generally mature within three to five years. Criticized commercial mortgage loans in the Commercial Real Estate business line 
totaled $378 million and $16 million at December 31, 2023 and 2022, respectively, with the increase primarily in multi-family 
properties.  In  other  business  lines,  $395  million  and  $151  million  of  commercial  mortgage  loans  were  criticized  at 
December 31, 2023 and 2022, respectively. Commercial mortgage loan net recoveries were $1 million in 2023, compared to no 
net charge-offs in 2022.

Substantially  all  dealer  loans  are  in  the  National  Dealer  Services  business  line  and  primarily  include  floor  plan 
financing  and  other  loans  to  automotive  dealerships.  Floor  plan  loans,  included  in  commercial  loans  in  the  Consolidated 
Balance  Sheets,  totaled  $2.3  billion  at  December  31,  2023,  an  increase  of  $934  million  compared  to  $1.4  billion  at 
December  31,  2022,  resulting  from  increasing  vehicle  levels  due  to  supply  chain  improvements.  At  December  31,  2023  and 
2022, other loans in the National Dealer Services business line totaled $3.9 billion and $4.0 billion, respectively, including $2.2 
billion and $2.3 billion of owner-occupied commercial real estate mortgage loans, respectively.

There were no nonaccrual dealer loans at both December 31, 2023, and 2022. Additionally, there were no net charge-

offs of dealer loans in either of the years ended December 31, 2023 and 2022.

Residential  real  estate  loans,  which  consist  of  traditional  residential  mortgages  and  home  equity  loans  and  lines  of 
credit,  totaled  $3.7  billion  at  December  31,  2023.  The  residential  real  estate  portfolio  is  principally  located  within  the 
Corporation's primary geographic markets. Substantially all residential real estate loans past due 90 days or more are placed on 
nonaccrual status, and substantially all junior lien home equity loans that are current or less than 90 days past due are placed on 
nonaccrual status if full collection of the senior position is in doubt. At no later than 180 days past due, such loans are charged 
off to current appraised values less costs to sell.

Residential mortgages totaled $1.9 billion at December 31, 2023, and were primarily larger, variable-rate mortgages 
originated  and  retained  for  certain  private  banking  relationship  customers.  Of  the  $1.9  billion  of  residential  mortgage  loans 
outstanding, $19 million were on nonaccrual status at December 31, 2023, a decrease of $34 million compared to December 31, 
2022.  The  home  equity  portfolio  totaled  $1.8  billion  at  December  31,  2023,  of  which  96  percent  was  outstanding  under 
primarily variable-rate, interest-only home equity lines of credit, 3 percent were in amortizing status and 1 percent were closed-
end  home  equity  loans.  Of  the  $1.8  billion  of  home  equity  loans  outstanding,  $21  million  were  on  nonaccrual  status  at 
December 31, 2023, an increase of $6 million compared to December 31, 2022. A majority of the home equity portfolio was 
secured by junior liens at December 31, 2023. 

Energy Lending

The  Corporation  has  a  portfolio  of  Energy  loans  that  are  included  entirely  in  commercial  loans  in  the  Consolidated 
Balance  Sheets.  Customers  in  the  Corporation's  Energy  business  line  (approximately  120  relationships)  are  engaged  in 
exploration and production (E&P) and midstream. E&P generally includes such activities as searching for potential oil and gas 
fields,  drilling  exploratory  wells  and  operating  active  wells.  Commitments  to  E&P  borrowers  are  generally  subject  to  semi-
annual  borrowing  base  re-determinations  based  on  a  variety  of  factors  including  updated  prices  (reflecting  market  and 
competitive  conditions),  energy  reserve  levels  and  the  impact  of  hedging.  The  midstream  sector  is  generally  involved  in  the 

F-25

 
 
 
 
 
 
 
 
 
 
 
 
 
 
transportation, storage and marketing of crude and/or refined oil and gas products. The Corporation's energy services customers 
provide  products  and  services  primarily  to  the  E&P  segment.  Approximately  94%  of  loans  in  the  Energy  business  line  are 
Shared  National  Credits  (SNC),  which  are  facilities  greater  than  or  equal  to  $100  million  shared  by  three  or  more  federally 
supervised  institutions,  reflecting  the  Corporation's  focus  on  larger  middle  market  companies  that  have  financing  needs  that 
generally exceed internal individual borrower credit risk limits. The Corporation seeks to develop full relationships with SNC 
borrowers.

Loans in the Energy business line totaled $1.4 billion, or 3 percent of total loans, at December 31, 2023, a decrease of 
$33  million  compared  to  December  31,  2022.  Total  exposure,  including  unused  commitments  to  extend  credit  and  letters  of 
credit, was $3.3 billion (a utilization rate of 42 percent) and $3.4 billion (a utilization of 43 percent) at December 31, 2023 and 
December 31, 2022, respectively. Nonaccrual Energy loans decreased $3 million to $4 million at December 31, 2023, compared 
to  $7  million  at  December  31,  2022.  Criticized  Energy  loans  decreased  $8  million  to  $4  million  at  December  31,  2023, 
compared to $12 million at December 31, 2022. Energy net recoveries were $1 million for the year ended December 31, 2023, 
compared to net charge-offs of $3 million for the year ended December 31, 2022. 

Leveraged Loans

Certain  loans  in  the  Corporation's  commercial  portfolio  are  considered  leveraged  transactions.  These  loans  are 
typically  used  for  mergers,  acquisitions,  business  recapitalizations,  refinancing  and  equity  buyouts.  To  help  mitigate  the  risk 
associated  with  these  loans,  the  Corporation  focuses  on  middle  market  companies  with  highly  capable  management  teams, 
strong sponsors and solid track records of financial performance. Industries prone to cyclical downturns and acquisitions with a 
high  degree  of  integration  risk  are  generally  avoided.  Other  considerations  include  the  sufficiency  of  collateral,  the  level  of 
balance sheet leverage and the adequacy of financial covenants. During the underwriting process, cash flows are stress-tested to 
evaluate the borrowers' abilities to handle economic downturns and an increase in interest rates. 

The FDIC defines higher-risk commercial and industrial (HR C&I) loans for assessment purposes as loans generally 
with leverage of four times total debt to earnings before interest, taxes and depreciation (EBITDA) as well as three times senior 
debt to EBITDA, excluding certain collateralized loans. 

The following table summarizes information about HR C&I loans, which represented 5 percent and 6 percent of total 

loans at December 31, 2023 and December 31, 2022, respectively.

Market and Liquidity Risk

Market risk represents the risk of loss due to adverse movement in prices, including interest rates, foreign exchange 
rates, commodity prices and equity prices. Liquidity risk represents the risk that the Corporation does not have sufficient access 
to funds to maintain its normal operations at all times or does not have the ability to raise or borrow funds at a reasonable cost 
at all times.

The Asset Liability Management Committee (ALCO) of the Corporation establishes and monitors compliance with the 
policies  and  risk  limits  pertaining  to  market  and  liquidity  risk  management  activities.  ALCO  meets  regularly  to  discuss  and 
review market and liquidity risk management strategies and consists of executive and senior management from various areas of 
the Corporation, including treasury, finance, economics, lending, deposit gathering and risk management. Corporate Treasury 
mitigates  market  and  liquidity  risk  under  the  direction  of  ALCO  through  the  actions  it  takes  to  manage  the  Corporation's 
market, liquidity and capital positions.

The Corporation performs monthly liquidity stress testing to evaluate its ability to meet funding needs in hypothetical 
stressed environments. Such environments cover a series of scenarios, including both idiosyncratic and market-wide in nature, 
which  vary  in  terms  of  duration  and  severity.  Recent  events  have  created  greater  uncertainty  with  respect  to  normal  deposit 
patterns.  Following  the  March  2023  banking  industry  disruption,  the  Corporation  activated  its  contingency  funding  plan  by 
increasing  its  cash  position  through  wholesale  funding  channels  and  brokered  deposits.  The  Corporation's  evaluation  as  of 
December 31, 2023 projected that sufficient sources of liquidity were available under each series of events.

In addition to assessing liquidity risk on a consolidated basis, Corporate Treasury also monitors the parent company's 
liquidity and has established liquidity coverage requirements for meeting expected obligations without the support of additional 
dividends from subsidiaries. ALCO's policy on liquidity risk management requires the parent company to maintain sufficient 
liquidity  to  meet  expected  cash  obligations,  such  as  debt  service,  dividend  payments  and  normal  operating  expenses,  over  a 
period of no less than 12 months. The Corporation had liquid assets of $1.4 billion on an unconsolidated basis at December 31, 
2023.

Corporate Treasury and the Enterprise Risk Division support ALCO in measuring, monitoring and managing interest 
rate risk as well as all other market risks. Key activities encompass: (i) providing information and analyses of the Corporation's 
balance  sheet  structure  and  measurement  of  interest  rate  and  all  other  market  risks;  (ii)  monitoring  and  reporting  of  the 
Corporation's  positions  relative  to  established  policy  limits  and  guidelines;  (iii)  developing  and  presenting  analyses  and 
strategies to adjust risk positions; (iv) reviewing and presenting policies and authorizations for approval; and (v) monitoring of 
industry trends and analytical tools to be used in the management of interest rate and all other market and liquidity risks.

Interest Rate Risk

Net interest income is the primary source of revenue for the Corporation. Interest rate risk arises in the normal course 
of  business  due  to  differences  in  the  repricing  and  cash  flow  characteristics  of  assets  and  liabilities,  primarily  through  the 
Corporation's  core  business  activities  of  extending  loans  and  acquiring  deposits.  The  Corporation's  balance  sheet  is 
predominantly  characterized  by  floating-rate  loans  funded  by  core  deposits.  Including  the  impact  of  interest  rate  swaps 
converting floating-rate loans to fixed, the Corporation's loan composition at December 31, 2023 was 40 percent fixed-rate, 51 
percent overnight to 30-day rate, 6 percent 90-day and greater rates and 3 percent prime. The composition of the loan portfolio 
creates  sensitivity  to  interest  rate  movements  due  to  the  imbalance  between  the  faster  repricing  of  the  floating-rate  loan 
portfolio versus deposit products. In addition, the growth and/or contraction in the Corporation's loans and deposits may lead to 
changes in sensitivity to interest rate movements in the absence of mitigating actions. Examples of such actions are purchasing 
fixed-rate  investment  securities,  which  provide  liquidity  to  the  balance  sheet  and  act  to  mitigate  the  inherent  interest  rate 
sensitivity,  as  well  as  hedging  with  interest  rate  swaps  and  options.  Other  mitigating  factors  include  interest  rate  floors  on  a 
portion of the loan portfolio.

The  Corporation  actively  manages  its  exposure  to  interest  rate  risk  with  the  principal  objective  of  optimizing  net 
interest income and the economic value of equity while operating within acceptable limits established for interest rate risk and 
maintaining adequate levels of funding and liquidity.

Since  no  single  measurement  system  satisfies  all  management  objectives,  a  combination  of  techniques  is  used  to 
manage interest rate risk. These techniques examine the impact of interest rate risk on net interest income and the economic 
value  of  equity  under  a  variety  of  alternative  scenarios,  including  changes  in  the  level,  slope  and  shape  of  the  yield  curve 
utilizing  multiple  simulation  analyses.  Simulation  analyses  produce  only  estimates  of  net  interest  income  as  the  assumptions 
used are inherently uncertain. Actual results may differ from simulated results due to many factors, including, but not limited 
to,  the  timing,  magnitude  and  frequency  of  changes  in  interest  rates,  market  conditions,  regulatory  impacts  and  management 
strategies.

F-27

Sensitivity of Net Interest Income to Changes in Interest Rates

The analysis of the impact of changes in interest rates on net interest income under various interest rate scenarios is 
management's principal risk management technique. Management models a base-case net interest income under an unchanged 
interest  rate  environment  using  a  static  balance  sheet  and  generates  sensitivity  scenarios  by  changing  certain  model 
assumptions.  Each  scenario  includes  assumptions  such  as  loan  growth,  investment  security  prepayment  levels,  depositor 
behavior and overall balance sheet mix and growth which are in line with historical patterns. Additionally, the analysis assumes 
that  all  loan  hedges  qualify  for  hedge  accounting.  Changes  in  actual  economic  activity  may  result  in  a  materially  different 
interest  rate  environment  as  well  as  a  balance  sheet  structure  that  is  different  from  the  changes  management  included  in  its 
simulation analysis. Model assumptions in the sensitivity scenarios at December 31, 2023 included for the rising rate scenarios, 
a modest increase in loan balances and a moderate decrease in deposit balances, and for the declining rate scenarios, a modest 
decrease in loan balances and a moderate increase in deposit balances. In addition, both scenarios assumed loan spreads held at 
current  levels,  an  incremental  interest-bearing  deposit  beta  of  approximately  48%,  deposit  mix  shifts  based  on  historical 
observations, partial reinvestment of securities portfolio cash flows and no additions to interest rate swaps. 

The average balance of the securities portfolio included in the analysis was $17.4 billion for the year ended December 

31, 2023 with an average yield of 2.10% and effective duration of 5.5 years.

The  analysis  also  includes  interest  rate  swaps  that  convert  $6.3  billion  of  fixed-rate  medium-  and  long-term  debt  to 
variable rates through fair value hedges. Additionally, included in this analysis are $15.5 billion of loans that were subject to an 
average interest rate floor of 52 basis points at December 31, 2023. This base-case net interest income is then compared against 
interest rate scenarios in which short-term rates rise or decline 100 or 200 basis points (with a floor of zero percent) in a linear, 
non-parallel  fashion  from  the  base  case  over  12  months,  resulting  in  an  average  change  of  50  or  100  basis  points  over  the 
period.

The table below, as of December 31, 2023 and 2022, displays the estimated impact on net interest income during the 

next 12 months by relating the base case scenario results to those from the rising and declining rate scenarios described above.

In both the 100 and 200 basis point scenarios, sensitivity to declining interest rates shifted from reducing net interest 
income at December 31, 2022 to benefiting net interest income at December 31, 2023, resulting from a decline in non-maturity 
deposits,  partially  offset  by  an  increase  in  time  deposits.  In  the  100  basis  point  scenario,  sensitivity  to  rising  interest  rates 
shifted from benefiting net interest income at December 31, 2022 to reducing net interest income at December 31, 2023, while 
in the 200 basis point scenario, negative sensitivity to rising interest rates increased compared to December 31, 2022, resulting 
from the change in liability mix that occurred in 2023.

F-28

 
 
 
 
 
 
 
At  December  31,  2023,  additional  sensitivity  scenarios  applied  the  rising  and  declining  100  basis  point  scenario 
assumptions with a 60% incremental deposit beta relative to the base case scenario to assess the impact of the Corporation's 
deposit beta assumptions. In these rising and declining scenarios, net interest income decreased by $65 million and increased by 
$44  million,  respectively,  due  to  a  more  rapid  repricing  pace  compared  to  the  standard  model  assumptions.  All  scenarios 
presented for December 31, 2023 reflected a change in balance sheet composition following the March 2023 banking industry 
disruption, as the balance sheet maintained a higher concentration of cash as well as increased wholesale funding and brokered 
deposits, which contributed to the decrease in net interest income in all scenarios presented.

Sensitivity of Economic Value of Equity to Changes in Interest Rates

In  addition  to  the  simulation  analysis  on  net  interest  income,  an  economic  value  of  equity  analysis  provides  an 
alternative view of the interest rate risk position. The economic value of equity is the difference between the estimate of the 
economic value of the Corporation's financial assets, liabilities and off-balance sheet instruments, derived through discounting 
cash flows based on actual rates at the end of the period, and the estimated economic value after applying the estimated impact 
of rate movements. The Corporation primarily monitors the percentage change on the base-case economic value of equity. The 
economic value of equity analysis is based on an immediate parallel 100 or 200 basis point shock with a floor of zero percent.

The table below, as of  December 31, 2023 and  December  31,  2022, displays  the estimated  impact on  the  economic 

value of equity from the interest rate scenario described above.

The  negative  sensitivity  of  the  economic  value  of  equity  to  rising  rates  increased  from  December  31,  2022  to 
December  31,  2023  due  to  deposit  runoff  and  adjustments  to  deposit  behavioral  assumptions,  partially  offset  by  a  declining 
notional  amount  of  cash  flow  swaps  and  a  smaller  securities  portfolio.  Sensitivity  to  declining  rates  increased  the  economic 
value of equity due to the same factors.

Risk Management Derivative Instruments

The Corporation uses investment securities and derivative instruments as asset and liability management tools with the 
overall objective of managing the volatility of net interest income from changes in interest rates. These tools assist management 
in achieving the desired interest rate risk management objectives. Activity related to derivative instruments currently involves 
interest rate swaps effectively converting fixed-rate medium- and long-term debt to a floating rate as well as variable rate loans 
to a fixed rate. Notional activity for 2023 included the impact of LIBOR transition for centrally-cleared swaps, where LIBOR-
based swaps were replaced with short-dated LIBOR bridge swaps that matured in 2023 and surviving forward-starting Secured 
Overnight Financing Rate (SOFR) swaps.

The  notional  amount  of  risk  management  interest  rate  swaps  totaled  $31.2  billion  at  December  31,  2023,  which 
included cash flow swaps that convert $24.9 billion of variable-rate loans to a fixed rate as well as fair value swaps that convert 
$6.3 billion of fixed-rate medium- and long-term debt to a floating rate. Risk management interest rate swaps generated $715 
million of net interest expense for the year ended December 31, 2023, compared to no impact for the year ended December 31, 
2022.  Of  the  $24.9  billion  of  cash  flow  swaps,  $7.0  billion  were  un-designated  for  accounting  purposes  as  of  December  31, 
2023. Refer to Note 8 to the consolidated financial statements for further discussion of de-designated interest rate hedges.

In addition to interest rate swaps, the Corporation employs various other types of derivative instruments as offsetting 
positions to mitigate exposures to foreign currency risks associated with specific assets and liabilities (e.g., customer loans or 
deposits denominated in foreign currencies). Such instruments may include foreign exchange spot and forward contracts as well 
as foreign exchange swap agreements.

Further  information  regarding  risk  management  derivative  instruments  is  provided  in  Note  8  to  the  consolidated 

financial statements.

The Corporation sells and purchases interest rate caps and floors and enters into foreign exchange contracts, interest 
rate swaps and energy derivative contracts to accommodate the needs of customers requesting such services. Changes in the fair 
value  of  customer-initiated  and  other  derivatives  are  recognized  in  earnings  as  they  occur.  To  limit  the  market  risk  of  these 
activities,  the  Corporation  generally  takes  offsetting  positions  with  dealers.  The  notional  amounts  of  offsetting  positions  are 
included in the table above. Customer-initiated and other notional activity represented 55 percent of total interest rate, energy 
and foreign exchange contracts at both December 31, 2023 and 2022, respectively.

Further  information  regarding  customer-initiated  and  other  derivative  instruments  is  provided  in  Note  8  to  the 

consolidated financial statements.

LIBOR Transition

On  July  27,  2017,  the  United  Kingdom’s  Financial  Conduct  Authority  (FCA),  which  regulates  LIBOR,  publicly 
announced that it intends to stop persuading or compelling banks to submit LIBOR rates after 2021. Effective March 2021, the 
FCA  confirmed  that  certain  LIBOR  tenors  would  no  longer  be  supported  after  December  31,  2021  and  that  the  remaining 
tenors,  including  those  most  commonly  used  by  the  Corporation,  would  no  longer  be  supported  after  June  30,  2023.  The 
Corporation had substantial exposure to LIBOR-based products, ceased originating LIBOR-based products in the fourth quarter 
2021  and  has  worked  to  remediate  its  outstanding  LIBOR  contracts.  As  of  December  31,  2023,  LIBOR  transition  was 
substantially complete.

BSBY Cessation

On  November  15,  2023,  the  Bloomberg  Index  Services  Limited  (Bloomberg)  announced  that  it  will  discontinue 
publishing  the  BSBY  on  November  15,  2024;  accordingly,  the  Corporation  was  required  to  “de-designate”  $7.0  billion  of 
interest rate swaps used in cash flow hedges of certain BSBY-indexed loans and reclassify amounts recognized in accumulated 
other comprehensive income into earnings. For each de-designated swap, settlement of interest payments and changes in fair 
value are recorded as risk management hedging losses within other noninterest income instead of net interest income until the 
swap is re-designated. In January 2024, $4.2 billion of these swaps were re-designated, with the remaining expected to be re-
designated in early 2024. The net impact of BSBY cessation to interest income on commercial loans was a $3 million benefit 
for the year ended December 31, 2023. Additionally, the Corporation recognized a net loss of $91 million in other noninterest 
income. Refer to Note 8 to the consolidated financial statements for further discussion of de-designated interest rate hedges.

At  December  31,  2023,  the  Corporation  had  $33.0  billion  of  exposure  to  BSBY-based  products,  including  $21.7 
billion in loans and $11.3 billion in interest rate swaps. The Corporation is currently evaluating contracts to ensure appropriate 
fallback language is included, and will remediate contracts as necessary. The Corporation expects that the majority of BSBY-
based  contracts  will  organically  transition  to  SOFR  over  the  upcoming  year,  with  any  remaining  contracts  transitioning  to 
SOFR through fallback language at the first repricing date after BSBY cessation occurs in November 2024. 

Sources of Liquidity

The  Corporation  maintains  a  liquidity  position  that  it  believes  will  adequately  satisfy  its  financial  obligations  while 
taking  into  account  potential  commitment  draws  and  deposit  run-off  that  may  occur  in  the  normal  course  of  business.  The 
majority  of  the  Corporation's  balance  sheet  is  funded  by  customer  deposits.  Cash  flows  from  loan  repayments,  increases  in 
deposit accounts (including brokered deposits), activity in the securities portfolio and wholesale funding channels serve as the 
Corporation's primary liquidity sources.

The Corporation satisfies incremental liquidity needs with either liquid assets or external funding sources. Available 
liquidity  includes  cash,  FHLB  advances  and  Federal  Reserve  Bank  (FRB)  borrowing,  comprised  of  borrowing  through  the 
discount window and the newly established Bank Term Funding Program (BTFP). The Corporation has pledged its investment 
securities portfolio to access wholesale funding as needed and does not intend to sell or restructure securities at this time.

F-31

 
 
 
 
 
 
 
 
 
 
 
 
 
 
The  Bank  is  a  member  of  the  FHLB  of  Dallas,  Texas,  which  provides  short-  and  long-term  funding  to  its  members 
through  advances  collateralized  by  real  estate-related  loans,  certain  government  agency-backed  securities  and  other  eligible 
assets. Actual borrowing capacity is contingent on the amount of collateral pledged to the FHLB and the fair value of pledged 
assets, as well as applicable FHLB haircuts.

At December 31, 2023, the Bank had pledged real estate-related loans totaling $21.9 billion and investment securities 

totaling $6.6 billion to the FHLB, which provided for up to $17.1 billion of collateralized borrowing with the FHLB.

The FRB provides liquidity through its discount window, where banks may borrow funds based on the discounted fair 
value  of  pledged  assets.  Additionally,  in  March  2023,  the  FRB  established  the  BTFP  in  response  to  the  2023  industry 
disruption, offering loans with up to one year in maturity to eligible depository institutions in exchange for pledged collateral in 
the  form  of  U.S  Treasuries,  agency  debt  and  mortgage-backed  securities  and  other  qualifying  assets.  Unlike  other  funding 
sources, borrowing capacity under the BTFP is based on the par value, not fair value, of collateral. 

At  December  31,  2023,  the  Bank  had  pledged  loans  totaling  $24.6  billion  and  investment  securities  totaling  $7.7 
billion  to  the  FRB,  which  provided  for  up  to  $21.0  billion  and  $9.3  billion  of  collateralized  borrowing  through  the  discount 
window and BTFP program, respectively. The Bank did not rely on the BTFP facility as a funding source, except to perform an 
operational  test  at  the  onset,  and  does  not  plan  to  use  the  facility  before  its  announced  expiration  on  March  11,  2024.  Total 
available collateralized borrowings with the FRB was $30.3 billion at December 31, 2023.

The Corporation may also use brokered deposits and external debt as additional sources of funding, and maintains a 
shelf registration statement with the Securities and Exchange Commission through which it may issue securities.The ability of 
the Corporation and the Bank to raise unsecured funding at competitive rates is impacted by rating agencies' views of the credit 
quality, liquidity, capital, earnings and other relevant factors related to the Corporation and the Bank. As of December 31, 2023, 
the three major rating agencies had assigned the following ratings to long-term senior unsecured obligations of the Corporation 
and  the  Bank,  as  well  as  long-term  deposits  at  the  Bank.  A  security  rating  is  not  a  recommendation  to  buy,  sell,  or  hold 
securities  and  may  be  subject  to  revision  or  withdrawal  at  any  time  by  the  assigning  rating  agency.  Each  rating  should  be 
evaluated independently of any other rating.

Deposit Concentrations and Uninsured Deposits

The  Corporation's  focus  is  commercial  customers,  and  accordingly,  it  has  a  larger  percentage  of  uninsured  deposits 
relative  to  financial  institutions  with  a  higher  consumer  focus.  These  deposits  are  well-diversified  between  geographies, 
industries and customers. At December 31, 2023, the Retail Bank and general Middle Market segments, both highly diversified 
and granular, accounted for 37% and 27% of the total deposit base, respectively. 

Uninsured deposits are defined as the portion of deposit accounts in U.S. offices that exceed the FDIC insurance limit 
and  amounts  in  any  other  uninsured  investment  or  deposit  account  that  are  classified  as  deposits  and  are  not  subject  to  any 
federal or state deposit insurance regimes.

entities  and  state  and  local  government  agencies,  totaled  $687  million  at  December  31,  2023,  compared  to  $843  million  at 
December 31, 2022.

Potential Uses of Liquidity

Various  financial  obligations  such  as  contractual  obligations,  unfunded  commitments  and  deposit  withdrawals  may 
require future cash payments by the Corporation. Certain obligations are recognized on the Consolidated Balance Sheets, while 
others are off-balance sheet under U.S. generally accepted accounting principles.

The following table summarizes the Corporation's material noncancelable contractual obligations and future required 
minimum payments. Refer to Notes 10, 11, 12, and 25 to the consolidated financial statements for further information regarding

Since  many  of  these  commitments  expire  without  being  fully  drawn,  and  each  customer  must  continue  to  meet  the

future cash requirements of the Corporation. Refer to Note 8 to the consolidated financial statements for a further discussion of 
these commercial commitments.

Other Market Risks

Market risk related to the Corporation's trading instruments is not significant, as trading activities are limited. Certain 
components of the Corporation's noninterest income, primarily fiduciary income, are at risk to fluctuations in the market values 
of underlying assets, particularly equity and debt securities. Other components of noninterest income, primarily brokerage fees, 
are at risk to changes in the volume of market activity.

Operational Risk

Operational risk represents the risk of loss resulting from inadequate or failed internal processes and people, or from 
external events, excluding in most cases those driven by technology (see Technology Risk below). The Corporation's definition 
of operational risk includes fraud; employment practice and workplace safety; clients, products and business practice; business 
continuity or disaster recovery; execution, delivery, and process management; third party and model risks. The definition does 
not  include  strategic  or  reputational  risks.  Although  operational  losses  are  experienced  by  all  companies  and  are  routinely 
incurred in business operations, the Corporation recognizes the need to identify and control operational losses and seeks to limit 
losses to a level deemed appropriate by management, as outlined in the Corporation’s risk appetite statement. The appropriate 
risk  level  is  determined  through  consideration  of  the  nature  of  the  Corporation's  business  and  the  environment  in  which  it 
operates, in combination with the impact from, and the possible impact on, other risks faced by the Corporation. Operational 
risk  is  mitigated  through  a  system  of  internal  controls  that  are  designed  to  keep  operating  risks  at  appropriate  levels.  The 
Operational Risk Management Committee monitors risk management techniques and systems. The Corporation has developed a 
framework that includes a centralized operational risk reporting function in the Enterprise Risk Division and business/support 
unit risk liaisons responsible for managing operational risk specific to the respective business lines.

Technology Risk

Technology risk represents the risk of loss or adverse outcomes arising from the people, processes, applications and 
infrastructure  that  support  the  technology  environment.  The  Corporation's  definition  of  technology  risk  includes  technology 
delivery  risk,  technology  investment  risk,  cybersecurity  risk,  information  security  risk  and  information  management  risk. 
Technology  risk  is  inclusive  of  the  risks  associated  with  the  execution  of  technology  processes  and  activities  by  third-party 
contractors and suppliers to the Corporation. Other risk types may materialize in the event of a technology risk event, such as 
the risk of a financial reporting error or regulatory non-compliance, and the impact of such risks are highly interdependent with 
operational risk.

The  Technology  Risk  Committee,  comprising  senior  and  executive  business  unit  managers,  as  well  as  managers 
responsible for technology, cybersecurity, information security and enterprise risk management, oversees technology risk. The 
Technology  Risk  Committee  also  ensures  that  appropriate  actions  are  implemented  in  business  units  to  mitigate  risk  to  an 
acceptable level.

Compliance Risk

Compliance  risk  represents  the  risk  of  sanctions  or  financial  loss  resulting  from  the  Corporation's  failure  to  comply 
with all applicable laws, regulations and standards of good banking practice. The impact of such risks is highly interdependent 
with  strategic  risk,  as  the  reputational  impact  from  compliance  breaches  can  be  severe.  Activities  which  may  expose  the 
Corporation to compliance risk include, but are not limited to, those dealing with the prevention of money laundering, privacy 
and data protection, community reinvestment initiatives, fair lending, consumer protection, employment and tax matters, over-
the-counter derivative activities and other regulated activities.

The  Enterprise-Wide  Compliance  Committee,  comprising  senior  and  executive  business  unit  managers,  as  well  as 
managers responsible for compliance, audit and overall risk, oversees compliance risk. This enterprise-wide approach provides 
a  consistent  view  of  compliance  across  the  organization.  The  Enterprise-Wide  Compliance  Committee  also  ensures  that 
appropriate actions are implemented in business units to mitigate risk to an acceptable level.

Strategic Risk

Strategic  risk  represents  the  risk  of  inadequate  returns  or  possible  losses  due  to  impairment  of  reputation,  failure  to 
fully  develop  and  execute  business  plans,  failure  to  assess  current  and  new  opportunities  in  business,  markets  and  products, 
failure  to  determine  appropriate  consideration  for  risks  accepted,  and  any  other  event  not  identified  in  the  defined  risk 
categories of credit, market and liquidity, operational, technology or compliance risks. Mitigation of the various risk elements 
that  represent  strategic  risk  is  achieved  through  numerous  metrics  and  initiatives  to  help  the  Corporation  better  understand, 
measure and report on such risks.

F-34

 
 
CRITICAL ACCOUNTING ESTIMATES

The Corporation’s consolidated financial statements are prepared based on the application of accounting policies, the 
most  significant  of  which  are  described  in  Note  1.  These  policies  require  numerous  estimates  and  strategic  or  economic 
assumptions,  which  may  prove  inaccurate  or  subject  to  variations.  Changes  in  underlying  factors,  assumptions  or  estimates 
could have a material impact on the Corporation’s future financial condition and results of operations. At December 31, 2023, 
the most critical of these estimates related to the allowance for credit losses, fair value measurement, goodwill, pension plan 
accounting  and  income  taxes.  These  estimates  were  reviewed  with  the  Audit  Committee  of  the  Corporation’s  Board  of 
Directors and are discussed more fully below.

ALLOWANCE FOR CREDIT LOSSES

In accordance with CECL, the allowance for credit losses, which includes both the allowance for loan losses and the 
allowance for credit losses on lending-related commitments, is calculated with the objective of maintaining a reserve for current 
expected credit losses over the remaining contractual life of the portfolio. The Corporation uses loss factors, based on estimated 
probability of default for internal risk ratings and loss given default, to determine the allowance for credit losses for the majority 
of  its  portfolio.  Management  applies  loss  factors  to  pools  of  loans  and  lending-related  commitments  with  similar  risk 
characteristics, calibrates these factors using economic forecasts and incorporates qualitative adjustments. For further discussion 
of the methodology used in the determination of the allowance for credit losses, refer to Note 1 to the consolidated financial 
statements. For further discussion on the economic forecast incorporated into the 2023 model, refer to the “Risk Management” 
section of this financial review. 

Management's  determination  of  the  appropriateness  of  the  allowance  is  based  on  periodic  evaluations  of  the  loan 
portfolio,  lending-related  commitments,  current  as  well  as  forecasted  economic  factors  and  other  relevant  information.  The 
calculation is inherently subjective and requires management to exercise significant judgment in developing assumptions for the 
estimate, the most significant of which are the loan risk rating process, development of economic forecasts and application of 
qualitative  adjustments.  Sensitivities  are  disclosed  to  demonstrate  how  changes  in  loan  risk  ratings  and  economic  forecast 
scenarios  may  impact  the  allowance  for  credit  losses.  Sensitivities  only  consider  changes  to  each  specific  assumption  in 
isolation and their impact to the quantitative modeled results. They do not contemplate impacts to the qualitative framework. 

Loan Risk Rating Process

Reserve  factors  are  applied  to  pools  of  loans  based  on  risk  characteristics,  including  the  Corporation's  internal  risk 
rating  system;  therefore,  loss  estimates  are  highly  dependent  on  the  accuracy  of  the  risk  rating  assigned  to  each  loan.  The 
inherent  imprecision  in  the  risk  rating  system  resulting  from  inaccuracy  in  assigning  and/or  entering  risk  ratings  in  the  loan 
accounting system is monitored by the Corporation's asset quality review function. Changes to internal risk ratings, beyond the 
forecasted  migration  inherent  in  the  credit  models,  would  result  in  a  different  estimated  allowance  for  credit  losses.  To 
illustrate, if 5 percent of the individual risk ratings were adjusted down by one rating across all pools, the allowance for loan 
losses as of December 31, 2023 would change by approximately $6 million.

Forecasted Economic Variables

Management  utilizes  models  through  which  historical  reserve  factor  estimates  are  calibrated  to  economic  forecasts 
over  the  reasonable  and  supportable  forecast  period  based  on  the  projected  performance  of  specific  economic  variables  that 
statistically  correlate  with  the  probability  of  default  and  loss  given  default  pools.  Loss  estimates  revert  to  historical  loss 
experience  for  contractual  lives  beyond  the  forecast  period.  Management  selects  economic  variables  it  believes  to  be  most 
relevant based on the composition of the loan portfolio and customer base, including forecasted levels of employment, gross 
domestic product, corporate bond and treasury spreads, industrial production levels, consumer and commercial real estate price 
indices as well as housing statistics.

The allowance for credit losses is highly sensitive to the economic forecasts used to develop the estimate. Due to the 
high level of uncertainty regarding significant assumptions, the Corporation evaluated a range of economic scenarios, including 
a more severe economic forecast scenario, with varying responses to current economic risks. The following table summarizes 
the more severe forecast scenario for the economic variables that are most impactful.

F-35

Economic Variable

More Severe Forecast
Contracts  through  third  quarter  2024,  peaking  at  a  decline  of  3.5 
percent annualized in second quarter 2024, subsequently improving 
to a 2.2 percent annual growth rate by the end of the forecast period.

Increases to 7.7 percent by first quarter 2025 followed by a gradual 
decline to 6.9 percent by the end of the forecast period.

Spreads  widen  to  a  peak  of  over  4.2  percent  before  gradually 
narrowing to 2.3 percent by the end of the forecast period.

Decline to $53 per barrel by first quarter 2025 before increasing to 
$61 per barrel by the end of the forecast period.

Selecting a different forecast in the current environment could result in a significantly different estimated allowance 
for credit losses. To illustrate, absent model overlays and other qualitative adjustments that are part of the quarterly reserving 
process,  if  the  Corporation  selected  the  more  severe  scenario  to  inform  its  models,  the  allowance  for  credit  losses  as  of 
December  31,  2023  would  increase  by  approximately  $376  million.  However,  factoring  in  model  overlays  and  qualitative 
adjustments could result in a materially different estimate under a more severe scenario.

Qualitative Adjustments and Model Overlays 

The Corporation includes qualitative adjustments, as appropriate, intended to capture the impact of uncertainties not 
reflected  in  the  quantitative  estimate,  including  foresight  risk,  model  imprecisions  and  input  imprecisions.  Qualitative 
adjustments  for  foresight  risk  reflect  the  inherent  imprecision  in  economic  forecasts  and  may  be  included  based  on 
management’s evaluation of different forecast scenarios, ranging from more benign to more severe, and known recent events 
impacting the Corporation’s portfolio. Model imprecision adjustments and model overlays may be included to mitigate known 
limitations  in  the  quantitative  models.  Input  imprecision  includes  adjustments  for  portfolios  where  recent  historical  losses 
exceed  expected  losses  or  known  recent  events  are  expected  to  alter  risk  ratings  once  evidence  is  acquired,  as  well  as  a 
qualitative assessment of the lending environment, including underwriting standards, current economic and political conditions, 
and  other  factors  affecting  credit  quality.  Qualitative  reserves  at  December  31,  2023  primarily  included  adjustments  for 
uncertainties related to forecasted economic variables.

Other Considerations

To  the  extent  actual  outcomes  differ  from  management  estimates,  additional  provision  for  credit  losses  may  be 
required  that  would  adversely  impact  earnings  in  future  periods.  The  allowance  is  assigned  to  business  segments,  and  any 
earnings impact resulting from actual outcomes differing from management estimates would primarily affect the Commercial 
Bank segment.

FAIR VALUE MEASUREMENT

Investment securities available-for-sale, derivatives and deferred compensation plan assets and associated liabilities are 
recorded at fair value on a recurring basis. Additionally, from time to time, other assets and liabilities may be recorded at fair 
value  on  a  nonrecurring  basis,  such  as  impaired  loans  that  have  been  measured  based  on  the  fair  value  of  the  underlying 
collateral,  loans  held-for-sale  recorded  at  the  lower  of  cost  or  market,  other  real  estate  (primarily  foreclosed  property), 
nonmarketable  equity  securities  and  certain  other  assets  and  liabilities.  Nonrecurring  fair  value  adjustments  typically  involve 
write-downs of individual assets or application of lower of cost or fair value accounting.

Fair value is an estimate of the exchange price that would be received to sell an asset or paid to transfer a liability in an 
orderly  transaction  (i.e.,  not  a  forced  transaction,  such  as  a  liquidation  or  distressed  sale)  between  market  participants  at  the 
measurement date and is based on the assumptions market participants would use when pricing an asset or liability. Fair value 
measurement and disclosure guidance establishes a three-level hierarchy for disclosure of assets and liabilities recorded at fair 
value. Notes 1 and 2 to the consolidated financial statements include information about the fair value hierarchy, the extent to 
which fair value is used to measure assets and liabilities, as well as the valuation methodologies and key inputs used. 

At December 31, 2023, assets and liabilities measured using observable inputs that are classified as Level 1 or Level 2 
represented substantially all of total assets and liabilities recorded at fair value, respectively. Valuations generated from model-
based techniques that use at least one significant assumption not observable in the market are considered Level 3 and reflect 
estimates  of  assumptions  market  participants  would  use  in  pricing  the  asset  or  liability.  The  valuation  of  Level  3  assets  and 
liabilities are considered critical accounting estimates.

F-36

GOODWILL

Goodwill  is  initially  recorded  as  the  excess  of  the  purchase  price  over  the  fair  value  of  the  net  assets  acquired  in  a 
business combination and is subsequently evaluated at least annually for impairment. Goodwill impairment testing is performed 
at the reporting unit level, equivalent to a business segment or one level below. The Corporation has three reporting units: the 
Commercial Bank, the Retail Bank, and Wealth Management. At December 31, 2023 and 2022, goodwill totaled $635 million, 
including $473 million allocated to the Commercial Bank, $101 million allocated to the Retail Bank, and $61 million allocated 
to Wealth Management.

The Corporation performs its annual evaluation of goodwill impairment in the third quarter of each year and may elect 
to  perform  a  quantitative  impairment  analysis  or  first  conduct  a  qualitative  analysis  to  determine  if  a  quantitative  analysis  is 
necessary.  Additionally,  the  Corporation  evaluates  goodwill  impairment  on  an  interim  basis  if  events  or  changes  in 
circumstances between annual tests indicate additional testing may be warranted to determine if goodwill might be impaired.

During the third quarter of 2023, the Corporation elected to perform a quantitative impairment analysis. The estimated 
fair  values  of  the  reporting  units  were  determined  using  a  blend  of  two  commonly  used  valuation  techniques:  the  market 
approach and the income approach. For the market approach, valuations of reporting units considered a combination of earnings 
and equity multiples from companies with characteristics similar to the reporting unit. Since the fair values determined under 
the  market  approach  are  representative  of  noncontrolling  interests,  the  valuations  incorporated  a  control  premium.  For  the 
income  approach,  estimated  future  cash  flows  were  derived  from  internal  forecasts  and  economic  expectations  for  each 
reporting  unit.  In  the  short-  and  mid-term,  forecasts  incorporated  current  economic  conditions  and  impacts  of  expected 
monetary  policy  decisions  by  the  Federal  Reserve  Bank.  Long-term  projections  reflected  normalized  rate  and  credit 
environments,  as  well  as  a  long-term  rate  of  return  for  each  reporting  unit.  Projections  were  discounted  using  an  applicable 
discount rate to calculate the fair value. The discount rate was based on the imputed cost of equity capital for each reporting 
unit,  which  incorporates  the  risk-free  rate  of  return,  a  market  equity  risk  premium,  potential  stock  volatility,  and  a  size  risk 
premium.  The  discount  rate  further  reflected  the  uncertainty  of  current  economic  conditions  and  potential  impacts  to  the 
forecasted financial information.

The combined fair value of all units was compared to the Corporation's market capitalization for reasonableness. At 
the  conclusion  of  the  quantitative  impairment  test  in  the  third  quarter  2023,  the  estimated  fair  values  of  all  reporting  units 
substantially  exceeded  their  carrying  amounts,  including  goodwill.  The  Corporation  performed  a  hypothetical  sensitivity 
analysis to evaluate the impact to the estimated fair value of each reporting unit from an adverse change in the discount rate. A 
100  basis  point  increase  in  the  discount  rate  would  result  in  the  fair  value  of  each  reporting  unit  to  continue  to  substantially 
exceed its carrying value.

The Corporation continues to monitor economic conditions that could significantly impact the impairment analysis and 
result in future goodwill impairment charges that, if incurred, could have a material adverse effect on the Corporation's results 
of operations in the period such charges are recognized. Additionally, any new legislative or regulatory changes not anticipated 
in management's expectations may cause the fair value of one or more of the reporting units to fall below the carrying value, 
resulting in a goodwill impairment charge. Any impairment charge would not affect the Corporation's regulatory capital ratios, 
tangible common equity ratio or liquidity position.

PENSION PLAN ACCOUNTING

The Corporation has a qualified and a non-qualified defined benefit pension plan. Effective January 1, 2017, benefits 
are calculated using a cash balance formula based on years of service, age, compensation and an interest credit based on the 30-
year Treasury rate. Participants under age 60 as of December 31, 2016 are eligible to receive a frozen final average pay benefit 
in addition to amounts earned under the cash balance formula. Participants age 60 or older as of December 31, 2016 continue to 
be eligible for a final average pay benefit. The Corporation makes assumptions concerning future events that will determine the 
amount  and  timing  of  required  benefit  payments,  funding  requirements  and  defined  benefit  pension  expense.  The  major 
assumptions are the discount rate used in determining the current benefit obligation, the long-term rate of return expected on 
plan assets, mix of assets within the portfolio and the projected mortality rate. 

The discount rate is determined by matching the expected cash flows of the pension plans to a portfolio of high quality 
corporate  bonds  as  of  the  measurement  date,  December  31.  The  long-term  rate  of  return  expected  on  plan  assets  is  set  after 
considering  both  long-term  returns  in  the  general  market  and  long-term  returns  experienced  by  the  assets  in  the  plan.  The 
current target asset allocation model for the plans is provided in Note 17 to the consolidated financial statements. The expected 
returns  on  these  various  asset  categories  are  blended  to  derive  one  long-term  return  assumption.  The  assets  are  primarily 
invested in certain collective investment funds, common stocks, U.S. Treasury and other U.S. government agency securities, as 
well as corporate and municipal bonds and notes. Mortality rate assumptions are based on mortality tables published by third 

F-37

parties such as the Society of Actuaries, considering other available information including historical data as well as studies and 
publications from reputable sources. 

The Corporation reviews its pension plan assumptions on an annual basis with its actuarial consultants to determine if 
the assumptions are reasonable and adjusts the assumptions to reflect changes in future expectations. The major assumptions 
used to calculate 2024 and 2023 defined benefit plan pension expense (benefit) were as follows:

Defined benefit plan benefit is expected to increase $19 million to approximately $45 million in 2024, compared to a 
benefit of $26 million in 2023. This includes service cost expense of $37 million and a benefit from other components of $82 
million. Service costs are included in salaries and benefits expense, while the benefit from other components are included in 
other noninterest expenses on the Consolidated Statements of Income.

The Corporation’s pension plan is most sensitive to changes in discount rate and long-term rate of return. A change to 
the  discount  rate  implies  a  corresponding  change  in  interest  rates  that  affect  the  value  of  the  plan’s  fixed  income  assets.  An 
increase of 25 basis points to the discount rate, including the effect of higher interest rates on the plan’s fixed income assets, 
would  result  in  a  net  increase  to  pension  expense  of  $6  million,  while  a  decrease  of  25  basis  points  would  reduce  pension 
expense by $6 million. Increasing the long-term rate of return by 25 basis points would reduce pension expense by $7 million, 
while a decrease of 25 basis points would increase pension expense by $7 million. 

Due  to  the  long-term  nature  of  pension  plan  assumptions,  actual  results  may  differ  significantly  from  the  actuarial-
based estimates. Differences resulting in actuarial gains or losses are required to be recorded in shareholders' equity as part of 
accumulated other comprehensive loss and amortized to defined benefit pension expense in future years. Refer to Note 17 to the 
consolidated financial statements for further information.

INCOME TAXES

The provision for income taxes is the sum of income taxes due for the current year and deferred taxes. Deferred taxes 
arise from temporary differences between the income tax basis and financial accounting basis of assets and liabilities. Accrued 
taxes represent the net estimated amount due to or to be received from taxing jurisdictions, currently or in the future, and are 
included in accrued income and other assets or accrued expenses and other liabilities on the Consolidated Balance Sheets. 

Included  in  net  deferred  taxes  are  deferred  tax  assets.  Deferred  tax  assets  are  evaluated  for  realization  based  on 
available evidence of projected future reversals of existing taxable temporary differences, assumptions made regarding future 
events and, when applicable, state loss carryback capacity. A valuation allowance is provided when it is more-likely-than-not 
that  some  portion  of  the  deferred  tax  asset  will  not  be  realized.  Determining  whether  deferred  tax  assets  are  realizable  is 
subjective and requires the use of significant judgment. 

The  Corporation  assesses  the  relative  risks  and  merits  of  tax  positions  for  various  transactions  after  considering 
statutes,  regulations,  judicial  precedent  and  other  available  information  and  maintains  tax  accruals  consistent  with  these 
assessments. This assessment is complex and requires judgment. The Corporation is subject to audit by taxing authorities that 
could question and/or challenge the tax positions taken by the Corporation. Changes in the estimate of accrued taxes occur due 
to  changes  in  tax  law,  interpretations  of  existing  tax  laws,  new  judicial  or  regulatory  guidance,  the  status  of  examinations 
conducted  by  taxing  authorities  that  impact  the  relative  risks  and  merits  of  tax  positions  taken  by  the  Corporation.  These 
changes,  when  they  occur,  impact  the  estimate  of  accrued  taxes  and  could  be  significant  to  the  operating  results  of  the 
Corporation. For further information on tax accruals and related risks, see Note 18 to the consolidated financial statements.

SUPPLEMENTAL FINANCIAL DATA

The Corporation believes non-GAAP measures are meaningful because they reflect adjustments commonly made by 
management, investors, regulators and analysts to evaluate the adequacy of common equity and performance trends. Tangible 
common  equity  is  used  by  the  Corporation  to  measure  the  quality  of  capital  and  the  return  relative  to  balance  sheet  risk. 
Common  equity  tier  1  capital  ratio  removes  preferred  stock  from  the  Tier  1  capital  ratio  as  defined  by  and  calculated  in 
conformity with bank regulations. The tangible common equity ratio removes the effect of intangible assets from capital and 
total  assets.  Tangible  common  equity  per  share  of  common  stock  removes  the  effect  of  intangible  assets  from  common 
shareholders' equity per share of common stock. 

The  following  table  provides  a  reconciliation  of  non-GAAP  financial  measures  and  regulatory  ratios  used  in  this 

financial review with financial measures defined by GAAP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

NOTE 1 - BASIS OF PRESENTATION AND ACCOUNTING POLICIES

Organization

Comerica  Incorporated  (the  Corporation)  is  a  registered  financial  holding  company  headquartered  in  Dallas,  Texas. 
The Corporation’s major business segments are the Commercial Bank, the Retail Bank and Wealth Management. For further 
discussion of each business segment, refer to Note 22. The Corporation and its banking subsidiaries are regulated at both the 
state and federal levels.

The  accounting  and  reporting  policies  of  the  Corporation  conform  to  United  States  (U.S.)  generally  accepted 
accounting  principles  (GAAP).  The  preparation  of  financial  statements  in  conformity  with  GAAP  requires  management  to 
make estimates and assumptions that affect reported amounts and disclosures. Actual results could differ from these estimates. 
Certain amounts in the financial statements for prior years have been reclassified to conform to the current financial statement 
presentation.

The  following  summarizes  the  significant  accounting  policies  of  the  Corporation  applied  in  the  preparation  of  the 

accompanying consolidated financial statements.

Principles of Consolidation

The consolidated financial statements include the accounts of the Corporation and the accounts of those subsidiaries 
that are majority owned and in which the Corporation has a controlling financial interest. The Corporation consolidates entities 
not determined to be variable interest entities (VIEs) when it holds a controlling financial interest and applies the cost or equity 
method  when  it  holds  less  than  a  controlling  financial  interest.  In  consolidation,  all  significant  intercompany  accounts  and 
transactions are eliminated. The results of operations of companies acquired are included from the date of acquisition.

The Corporation holds investments in certain legal entities that are considered VIEs. In general, a VIE is an entity that 
either  (1)  has  an  insufficient  amount  of  equity  to  carry  out  its  principal  activities  without  additional  subordinated  financial 
support, (2) has a group of equity owners that are unable to make significant decisions about its activities, or (3) has a group of 
equity owners that do not have the obligation to absorb losses or the right to receive returns generated by its operations. If any 
of these characteristics are present, the entity is subject to a variable interests consolidation model, and consolidation is based 
on variable interests, not on voting interests. Variable interests are defined as contractual ownership or other economic interests 
in an entity that change with fluctuations in the entity’s net asset value. The primary beneficiary is required to consolidate the 
VIE as it has both the power to direct the activities of the VIE that most significantly impact the entity’s economic performance 
and the obligation to absorb losses or the right to receive benefits that could be significant to the VIE. The maximum potential 
exposure to losses relative to investments in VIEs is generally limited to the sum of the outstanding book basis and unfunded 
commitments for future investments.

The Corporation evaluates its investments in VIEs, both at inception and when there is a change in circumstances that 
requires  reconsideration,  to  determine  if  the  Corporation  is  the  primary  beneficiary  and  consolidation  is  required.  The 
Corporation accounts for unconsolidated VIEs using either the proportional, cost or equity method. These investments comprise 
investments  in  community  development  projects  which  generate  tax  credits  to  their  investors  and  are  included  in  accrued 
income and other assets on the Consolidated Balance Sheets.

The  proportional  method  is  used  for  investments  in  affordable  housing  projects  that  qualify  for  the  low-income 
housing tax credit (LIHTC). The equity method is used for other investments where the Corporation has the ability to exercise 
significant  influence  over  an  entity’s  operations  and  financial  policies.  Other  unconsolidated  equity  investments  that  do  not 
meet the criteria to be accounted for under the equity method are accounted for under the cost method. Amortization and other 
write-downs  of  LIHTC  investments  are  presented  on  a  net  basis  as  a  component  of  the  provision  for  income  taxes,  while 
income, amortization and write-downs from cost and equity method investments are recorded in other noninterest income on 
the Consolidated Statements of Income.

See Note 9 for additional information about the Corporation’s involvement with VIEs.

Assets  held  in  an  agency  or  fiduciary  capacity  are  not  assets  of  the  Corporation  and  are  not  included  in  the 

consolidated financial statements.

Comerica Incorporated and Subsidiaries

Fair Value Measurements

The Corporation utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to 
determine fair value disclosures. The determination of fair values of financial instruments often requires the use of estimates. In 
cases where quoted market values in an active market are not available, the Corporation uses present value techniques and other 
valuation  methods  to  estimate  the  fair  values  of  its  financial  instruments.  These  valuation  methods  require  considerable 
judgment and the resulting estimates of fair value can be significantly affected by the assumptions made and methods used.

Fair value is an estimate of the exchange price that would be received to sell an asset or paid to transfer a liability in an 
orderly  transaction  (i.e.,  not  a  forced  transaction,  such  as  a  liquidation  or  distressed  sale)  between  market  participants  at  the 
measurement date. Fair value is based on the assumptions market participants would use when pricing an asset or liability.

Investment  securities  available-for-sale,  derivatives,  deferred  compensation  plans  and  equity  securities  with  readily 
determinable fair values (primarily money market mutual funds) are recorded at fair value on a recurring basis. Additionally, 
from time to time, the Corporation may be required to record other assets and liabilities at fair value on a nonrecurring basis, 
such as impaired loans, loans held for sale, other real estate (primarily foreclosed property), nonmarketable equity securities and 
certain other assets and liabilities. These nonrecurring fair value adjustments typically involve write-downs of individual assets 
or application of lower of cost or fair value accounting.

Fair value measurements and disclosures guidance establishes a three-level fair value hierarchy based on the markets 
in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. The fair value 
hierarchy gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data. Fair value 
measurements are separately disclosed by level within the fair value hierarchy. For assets and liabilities recorded at fair value, it 
is  the  Corporation’s  policy  to  maximize  the  use  of  observable  inputs  and  minimize  the  use  of  unobservable  inputs  when 
developing fair value measurements.

Level 1

Valuation is based on quoted prices for identical instruments traded in active markets.

Level 2

Level 3

Valuation is based on quoted prices for similar instruments in active markets, quoted prices for identical 
or similar instruments in markets that are less active, and model-based valuation techniques for which all 
significant assumptions are observable in the market.

Valuation  is  generated  from  model-based  techniques  that  use  at  least  one  significant  assumption  not 
observable in the market. These unobservable assumptions reflect estimates of assumptions that market 
participants would use in pricing the asset or liability. Valuation techniques include use of option pricing 
models, discounted cash flow models and similar techniques.

The Corporation generally utilizes third-party pricing services to value Level 1 and Level 2 securities. Management 
reviews  the  methodologies  and  assumptions  used  by  the  third-party  pricing  services  and  evaluates  the  values  provided, 
principally by comparison with other available market quotes for similar instruments and/or analysis based on internal models 
using  available  third-party  market  data.  The  Corporation  may  occasionally  adjust  certain  values  provided  by  the  third-party 
pricing service when management believes, as the result of its review, that the adjusted price most appropriately reflects the fair 
value of the particular security.

Fair  value  measurements  for  assets  and  liabilities  where  limited  or  no  observable  market  data  exists  are  based 
primarily upon estimates, often calculated based on the economic and competitive environment, the characteristics of the asset 
or liability and other factors. Therefore, the results cannot be determined with precision and may not be realized in an actual 
sale  or  immediate  settlement  of  the  asset  or  liability.  Additionally,  there  may  be  inherent  weaknesses  in  any  calculation 
technique,  so  that  changes  in  the  underlying  assumptions  used,  including  discount  rates  and  estimates  of  future  cash  flows, 
could significantly affect the results of current or future values.

Following  are  descriptions  of  the  valuation  methodologies  and  key  inputs  used  to  measure  financial  assets  and 
liabilities recorded at fair value, as well as a description of the methods and significant assumptions used to estimate fair value 
disclosures for financial instruments not recorded at fair value in their entirety on a recurring basis. The descriptions include an 
indication of the level of the fair value hierarchy in which the assets or liabilities are classified. 

Deferred compensation plan assets and liabilities as well as equity securities with a readily determinable fair value

The  Corporation  holds  a  portfolio  of  securities  that  includes  equity  securities  and  assets  held  related  to  deferred 
compensation plans. Securities and associated deferred compensation plan liabilities are recorded at fair value on a recurring 
basis and included in other short-term investments and accrued expenses and other liabilities, respectively, on the Consolidated 
Balance Sheets. Level 1 securities include assets related to deferred compensation plans, which are invested in mutual funds, 
U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets and other securities traded on 

F-48

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

an active exchange, such as the New York Stock Exchange. Level 2 securities include municipal bonds and mortgage-backed 
securities  issued  by  U.S.  government-sponsored  entities  and  corporate  debt  securities.  Deferred  compensation  plan  liabilities 
represent the fair value of the obligation to the plan participant, which corresponds to the fair value of the invested assets. The 
methods  used  to  value  equity  securities  and  deferred  compensation  plan  assets  are  the  same  as  the  methods  used  to  value 
investment securities, discussed below.

Investment securities available-for-sale

Investment securities available-for-sale are recorded at fair value on a recurring basis. Level 1 securities include those 
traded  on  an  active  exchange,  such  as  the  New  York  Stock  Exchange,  U.S.  Treasury  securities  that  are  traded  by  dealers  or 
brokers  in  active  over-the-counter  markets  and  money  market  funds.  Level  2  securities  include  mortgage-backed  securities 
issued by U.S. government agencies and U.S. government-sponsored entities, as well as corporate debt securities. The fair value 
of  Level  2  securities  is  determined  using  quoted  prices  of  securities  with  similar  characteristics,  or  pricing  models  based  on 
observable market data inputs, primarily interest rates, spreads and prepayment information.

Securities  classified  as  Level  3  represent  securities  in  less  liquid  markets  requiring  significant  management 

assumptions when determining fair value. 

Loans held-for-sale

Loans held-for-sale, included in other short-term investments on the Consolidated Balance Sheets, are recorded at the 
lower of cost or fair value. Loans held-for-sale may be carried at fair value on a nonrecurring basis when fair value is less than 
cost. When the fair value is based on what secondary markets are currently offering for portfolios with similar characteristics, 
the loans are classified as Level 2. When secondary market information is not available, the fair value is estimated based on the 
repricing  frequency  of  the  loans  and  estimated  credit  risk  using  internally-developed  lifetime  loss  estimates,  resulting  in  the 
loans being classified as Level 3. 

Loans

The Corporation does not  record  loans  at  fair value on a recurring  basis.  However,  an individual  allowance may be 
established for a loan that no longer shares risk characteristics with loan pools, typically collateral-dependent loans for which 
reserves  are  based  on  the  fair  value  of  the  underlying  collateral.  Such  loan  values  are  reported  as  nonrecurring  fair  value 
measurements. Collateral values supporting individually evaluated loans are evaluated quarterly. When management determines 
that the fair value of the collateral requires additional adjustments, either as a result of non-current appraisal value or when there 
is no observable market price, the Corporation classifies the loan as Level 3. 

Derivative assets and derivative liabilities

Derivative  instruments  held  or  issued  for  risk  management  or  customer-initiated  activities  are  traded  in  over-the-
counter markets where quoted market prices are not readily available. Fair value for over-the-counter derivative instruments is 
measured on a recurring basis using internally developed models primarily based on market observable inputs, such as yield 
curves and option volatilities. The Corporation manages credit risk on its derivative positions based on whether the derivatives 
are settled through a clearinghouse or bilaterally with each counterparty. For derivative positions settled on a counterparty-by-
counterparty basis, the Corporation calculates credit valuation adjustments, included in the fair value of these instruments, on 
the basis of its relationships at the counterparty portfolio or master netting agreement level. These credit valuation adjustments 
are  determined  by  applying  a  credit  spread  for  the  counterparty  or  the  Corporation,  as  appropriate,  to  the  total  expected 
exposure  of  the  derivative  after  considering  collateral  and  other  master  netting  arrangements.  These  adjustments,  which  are 
considered Level 3 inputs, are based on estimates of current credit spreads to evaluate the likelihood of default. When credit 
valuation  adjustments  are  significant  to  the  overall  fair  value  of  a  derivative,  the  Corporation  classifies  the  over-the-counter 
derivative  valuation  in  Level  3  of  the  fair  value  hierarchy;  otherwise,  over-the-counter  derivative  valuations  are  classified  in 
Level 2.

Other real estate

Other  real  estate  is  included  in  accrued  income  and  other  assets  on  the  Consolidated  Balance  Sheets  and  includes 
primarily foreclosed property. Foreclosed property is initially recorded at fair value, less costs to sell, at the date of legal title 
transfer to the Corporation, establishing a new cost basis. Subsequently, foreclosed property is carried at the lower of cost or 
fair value, less costs to sell. Other real estate may be carried at fair value on a nonrecurring basis when fair value is less than 
cost.  Fair  value  is  based  upon  independent  market  prices,  appraised  value  or  management's  estimate  of  the  value  of  the 
property. When management determines that the fair value of other real estate requires additional adjustments, either as a result 

F-49

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

of a non-current appraisal or when there is no observable market price, the Corporation classifies the other real estate as Level 
3.

For further information about fair value measurements refer to Note 2.

Other Short-Term Investments

Other short-term investments include deferred compensation plan assets, certificates of deposits, equity securities with 

a readily determinable fair value and loans held-for-sale. 

Deferred  compensation  plan  assets  and  equity  securities  are  carried  at  fair  value.  Realized  and  unrealized  gains  or 

losses are included in other noninterest income on the Consolidated Statements of Income.

Loans  held-for-sale  include  variable-rate  demand  notes,  residential  mortgages  originated  with  the  intent  to  sell  and 
occasionally other loans transferred to held-for-sale. Loans held-for-sale are carried at the lower of cost or fair value. Fair value 
is  determined  in  the  aggregate  for  each  portfolio.  Changes  in  fair  value  and  gains  or  losses  upon  sale  are  included  in  other 
noninterest income on the Consolidated Statements of Income.

Investment Securities

Debt securities are classified as trading, available-for-sale (AFS) or held-to-maturity. Trading securities are recorded at 
fair  value,  with  unrealized  gains  and  losses  included  in  noninterest  income  on  the  Consolidated  Statements  of  Income.  AFS 
securities are recorded at fair value, with unrealized gains and losses, net of income taxes, reported as a separate component of 
other  comprehensive  income  (OCI).  Securities  for  which  management  has  the  intent  and  ability  to  hold  to  maturity  are 
classified  as  held-to-maturity  and  recorded  at  amortized  cost.  Interest  income  is  recognized  using  the  interest  method. 
Substantially all of the Corporation's investment securities are classified as AFS at December 31, 2023 and 2022.

An AFS security is impaired if its fair value is less than amortized cost. Credit-related impairment is recognized as an 
allowance  to  investment  securities  available-for-sale  on  the  Consolidated  Balance  Sheets  with  a  corresponding  adjustment  to 
provision  for  credit  losses  on  the  Consolidated  Statements  of  Income.  Non-credit-related  impairment  is  recognized  as  a 
component of OCI. If the Corporation intends to sell an impaired AFS security or more likely than not will be required to sell 
that  security  before  recovering  its  amortized  cost  basis,  the  entire  impairment  amount  is  recognized  in  earnings  with 
corresponding adjustment to the security's amortized cost basis.

For  certain  types  of  AFS  securities,  such  as  U.S.  Treasuries  and  other  securities  with  government  guarantees,  the 
Corporation  generally  expects  zero  credit  losses.  The  zero-loss  expectation  applies  to  all  the  Corporation’s  securities  and  no 
allowance for credit losses was recorded on its AFS securities portfolio at December 31, 2023.

Gains or losses on the sale of securities are computed based on the adjusted cost of the specific security sold.

For further information on investment securities, refer to Note 3.

Loans

Loans and leases originated and held for investment are recorded at the principal balance outstanding, net of unearned 
income,  charge-offs  and  unamortized  deferred  fees  and  costs.  Interest  income  is  recognized  on  loans  and  leases  using  the 
interest method.

Effective  January  1,  2023,  the  Corporation  assesses  all  loan  modifications  to  determine  whether  one  is  granted  to  a 
borrower experiencing financial difficulty, regardless of whether the modified loan terms include a concession. Modifications 
granted  to  borrowers  experiencing  financial  difficulty  may  be  in  the  form  of  an  interest  rate  reduction,  an  other-than-
insignificant  payment  delay,  a  term  extension,  principal  forgiveness  or  a  combination  thereof  (collectively  referred  to  as 
Financially  Distressed  Modifications  or  FDMs).  Prior  to  2023,  the  Corporation  assessed  all  loan  modifications  to  determine 
whether  a  restructuring  constituted  a  troubled  debt  restructuring  (TDR).  A  restructuring  was  considered  a  TDR  when  a 
borrower was experiencing financial difficulty and the Corporation granted a concession to the borrower. 

Certain types of modifications related to COVID-19 that were granted during 2020 and 2021 were excluded from TDR 

accounting. See Note 1 in the 2021 10-K for additional information.

Effective  January  1,  2020,  the  Corporation  adopted  ASU  No.  2020-04  "Reference  Rate  Reform  (Topic  848): 
Facilitation of the Effects of Reference Rate Reform on Financial Reporting," (ASU 2020-04). Typically, entities must evaluate 
whether a loan contract modification results in a modified loan or a new loan for accounting purposes. Topic 848 allows entities 
to  bypass  this  evaluation  for  qualifying  modifications  related  to  reference  rate  reform.  The  Corporation  applied  the  relief 

F-50

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

provided  by  Topic  848  to  qualifying  contract  modifications  transitioning  away  from  LIBOR.  After  LIBOR  transition  was 
substantially complete in third quarter 2023, the Corporation no longer applied the relief guidance. 

Loan Origination Fees and Costs

Substantially all loan origination fees and costs are deferred and amortized to net interest income over the life of the 
related loan or over the commitment period as a yield adjustment. Net deferred income on originated loans, including unearned 
income and unamortized costs, fees, premiums and discounts, totaled $94 million and $118 million at December 31, 2023 and 
2022, respectively. 

Loan fees on unused commitments and net origination fees related to loans sold are recognized in noninterest income.

 Allowance for Credit Losses

The  allowance  for  credit  losses  includes  both  the  allowance  for  loan  losses  and  the  allowance  for  credit  losses  on 

lending-related commitments.

The Corporation disaggregates the loan portfolio into segments for purposes of determining the allowance for credit 
losses.  These  segments  are  based  on  the  level  at  which  the  Corporation  develops,  documents  and  applies  a  systematic 
methodology to determine the allowance for credit losses. The Corporation's portfolio segments are business loans and retail 
loans. Business loans include the commercial, real estate construction, commercial mortgage, lease financing and international 
loan portfolios. Retail loans consist of residential mortgage and consumer loans, including home equity loans.

Current  expected  credit  losses  are  estimated  over  the  contractual  life  of  the  loan  portfolio,  considering  all  available 
relevant  information,  including  historical  and  current  conditions  as  well  as  reasonable  and  supportable  forecasts  of  future 
events. 

For further information on the Allowance for Credit Losses, refer to Note 4.

Allowance for Loan Losses

The  allowance  for  loan  losses  is  estimated  on  a  quarterly  basis  and  represents  management’s  estimates  of  current 
expected  credit  losses  in  the  Corporation’s  loan  portfolio.  Pools  of  loans  with  similar  risk  characteristics  are  collectively 
evaluated while loans that no longer share risk characteristics with loan pools are evaluated individually. 

Collective loss estimates are determined by applying loss factors, designed to estimate current expected credit losses, 
to amortized cost balances over the remaining contractual life of the collectively evaluated portfolio. Loans with similar risk 
characteristics are aggregated into homogeneous pools. Business loans are assigned to pools based primarily on business line 
and  the  Corporation’s  internal  risk  rating  system.  For  retail  loans,  pools  are  based  on  loan  type,  past  due  status  and  credit 
scores. Loss factors are based on an estimated probability of default for each pool, set to a default horizon based on contractual 
life,  and  loss  given  default.  Historical  estimates  are  calibrated  to  economic  forecasts  over  the  reasonable  and  supportable 
forecast period based on the projected performance of specific economic variables that statistically correlate with each of the 
probability of default and loss given default pools. At least annually, management considers different models when estimating 
credit losses, selecting ones that most reasonably forecast credit losses in the relevant economic environment.

The  calculation  of  current  expected  credit  losses  is  inherently  subjective,  as  it  requires  management  to  exercise 
judgment  in  determining  appropriate  factors  used  to  determine  the  allowance.  Some  of  the  most  significant  factors  in  the 
quantitative allowance estimate are assigning internal risk ratings to loans, selecting the economic forecasts used to calibrate the 
reserve factors and determining the reasonable and supportable forecast period.

•

•

•

Internal  Risk  Ratings:  Loss  factors  are  dependent  on  loan  risk  ratings  for  business  loans.  Risk  ratings  are  assigned  at 
origination, based on inherent credit risk, and updated based on new information that becomes available, periodic reviews 
of credit quality, a change in borrower performance or modifications to lending agreements.

Economic Forecasts: Management selects economic variables it believes to be most relevant based on the composition of 
the loan portfolio and customer base, including forecasted levels of employment, gross domestic product, corporate bond 
and  treasury  spreads,  industrial  production  levels,  consumer  and  commercial  real  estate  price  indices  as  well  as  housing 
statistics.  Different  economic  forecast  scenarios  ranging  from  more  benign  to  more  severe  are  evaluated  each  reporting 
period to forecast losses over the contractual life of the loan portfolio.

Forecast  Period:  Economic  forecasts  are  applied  over  the  period  management  believes  it  can  estimate  reasonable  and 
supportable forecasts. Forecast periods may be adjusted in response to changes in the economic environment. To estimate 
losses for contractual periods that extend beyond the forecast horizon, the Corporation reverts to an average historical loss 

F-51

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

experience.  The  Corporation  typically  forecasts  economic  variables  over  a  two-year  horizon,  followed  by  an  immediate 
reversion to an average historical loss experience that generally incorporates a full economic cycle. Management reviews 
this methodology on at least an annual basis. 

The  allowance  for  loan  losses  also  includes  qualitative  adjustments  to  bring  the  allowance  to  the  level  management 
believes is appropriate based on factors that have not otherwise been fully accounted for, including adjustments for foresight 
risk,  input  imprecision  and  model  imprecision.  Foresight  risk  reflects  the  inherent  imprecision  in  forecasting  economic 
variables,  including  determining  the  depth  and  duration  of  economic  cycles  and  their  impact  to  relevant  economic  variables. 
The  Corporation  may  make  qualitative  adjustments  based  on  its  evaluation  of  different  forecast  scenarios  and  known  recent 
events  impacting  relevant  economic  variables.  Input  imprecision  factors  address  the  risk  that  certain  model  inputs  may  not 
reflect all available information including (i) risk factors that have not been fully addressed in internal risk ratings, (ii) changes 
in  lending  policies  and  procedures,  (iii)  changes  in  the  level  and  quality  of  experience  held  by  lending  management,  (iv) 
imprecision  in  the  risk  rating  system  and  (v)  limitations  in  data  available  for  certain  loan  portfolios.  Model  imprecision 
considers known model limitations and model updates not yet fully reflected in the quantitative estimate.

The determination of the appropriate qualitative adjustment is based on management's analysis of current and expected 
economic conditions and their impact to the portfolio, as well as internal credit risk movements and a qualitative assessment of 
the  lending  environment,  including  underwriting  standards.  Management  recognizes  the  sensitivity  of  various  assumptions 
made  in  the  quantitative  modeling  of  expected  losses  and  may  adjust  reserves  depending  upon  the  level  of  uncertainty  that 
currently exists in one or more assumptions.

Credit losses for loans that no longer share risk characteristics with the loan pools are estimated on an individual basis. 
Individual credit loss estimates are typically performed for nonaccrual loans and are based on one of several methods, including 
the estimated fair value of the underlying collateral, observable market value of similar debt or the present value of expected 
cash  flows.  The  Corporation  considers  certain  loans  to  be  collateral-dependent  if  the  borrower  is  experiencing  financial 
difficulty and management expects repayment for the loan to be substantially through the operation or sale of the collateral. For 
collateral-dependent  loans,  loss  estimates  are  based  on  the  fair  value  of  collateral,  less  estimated  cost  to  sell  (if  applicable). 
Collateral  values  supporting  individually  evaluated  loans  are  assessed  quarterly  and  appraisals  are  typically  obtained  at  least 
annually.

The  total  allowance  for  loan  losses  is  sufficient  to  absorb  expected  credit  losses  over  the  contractual  life  of  the 
portfolio.  Unanticipated  events  impacting  the  economy,  including  political  instability  or  global  events  affecting  the  U.S. 
economy,  could  cause  changes  to  expectations  for  current  conditions  and  economic  forecasts  that  result  in  an  unanticipated 
increase  in  the  allowance.  Significant  increases  in  current  portfolio  exposures  or  changes  in  credit  characteristics  could  also 
increase the amount of the allowance. Such events, or others of similar nature, may result in the need for additional provision 
for credit losses in order to maintain an allowance that complies with credit risk and accounting policies.

Loans deemed uncollectible are charged off and deducted from the allowance. Recoveries on loans previously charged 

off are added to the allowance.

Credit  losses  are  not  estimated  for  accrued  interest  receivable  as  interest  that  is  deemed  uncollectible  is  written  off 

through interest income.

Allowance for Credit Losses on Lending-Related Commitments

The allowance for credit losses on lending-related commitments estimates current expected credit losses on collective 
pools of letters of credit and unused commitments to extend credit based on reserve factors, determined in a manner similar to 
business  loans,  multiplied  by  a  probability  of  draw  estimate,  based  on  historical  experience  and  credit  risk,  applied  to 
commitment  amounts.  The  allowance  for  credit  losses  on  lending-related  commitments  is  included  in  accrued  expenses  and 
other liabilities on the Consolidated Balance Sheets, with the corresponding charge included in the provision for credit losses on 
the Consolidated Statements of Comprehensive Income.

Nonperforming Assets

Nonperforming assets consist of nonaccrual loans, reduced-rate loans and foreclosed property.

A  loan  is  considered  past  due  when  the  contractually  required  principal  or  interest  payment  is  not  received  by  the 
specified  due  date  or,  for  certain  loans,  when  a  scheduled  monthly  payment  is  past  due  and  unpaid  for  30  days  or  more. 
Business loans are generally placed on nonaccrual status when management determines full collection of principal or interest is 
unlikely or when principal or interest payments are 90 days past due, unless the loan is fully collateralized and in the process of 
collection. The past-due status of a business loan is one of many indicative factors considered in determining the collectibility 

F-52

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

of  the  credit.  The  primary  driver  of  when  the  principal  amount  of  a  business  loan  should  be  fully  or  partially  charged-off  is 
based  on  a  qualitative  assessment  of  the  recoverability  of  the  principal  amount  from  collateral  and  other  cash  flow  sources. 
Residential mortgage and home equity loans are generally placed on nonaccrual status once they become 90 days past due and 
are charged off to current appraised values less costs to sell no later than 180 days past due. In addition, junior lien home equity 
loans  less  than  90  days  past  due  are  placed  on  nonaccrual  status  if  they  have  underlying  risk  characteristics  that  place  full 
collection of the loan in doubt, such as when the related senior lien position is identified as seriously delinquent. Residential 
mortgage and consumer loans in bankruptcy for which the court has discharged the borrower's obligation and the borrower has 
not reaffirmed the debt are placed on nonaccrual status and written down to estimated collateral value, without regard to the 
actual payment status of the loan. All other consumer loans are generally placed on nonaccrual status at 90 days past due and 
are charged off at no later than 120 days past due, or earlier if deemed uncollectible. 

At  the  time  a  loan  is  placed  on  nonaccrual  status,  interest  previously  accrued  but  not  collected  is  charged  against 
current income. Principal and interest payments received on such loans are generally first applied as a reduction of principal. 
Income on nonaccrual loans is then recognized only to the extent that cash is received after principal has been fully repaid or 
future collection of principal is probable. Generally, a loan may be returned to accrual status when all delinquent principal and 
interest have been received and the Corporation expects repayment of the remaining contractual principal and interest, or when 
the loan or debt security is both well secured and in the process of collection.

Foreclosed property (primarily real estate) is initially recorded at fair value, less costs to sell, at the date of legal title 
transfer to the Corporation and subsequently carried at the lower of cost or fair value, less estimated costs to sell. Loans are 
reclassified to foreclosed property upon obtaining legal title to the collateral. Independent appraisals are obtained to substantiate 
the fair value of foreclosed property at the time of foreclosure and updated at least annually or upon evidence of deterioration in 
the  property’s  value.  At  the  time  of  foreclosure,  the  adjustment  for  the  difference  between  the  related  loan  balance  and  fair 
value (less estimated costs to sell) of the property acquired is charged or credited to the allowance for loan losses. Subsequent 
write-downs,  operating  expenses  and  losses  upon  sale,  if  any,  are  charged  to  noninterest  expenses.  Foreclosed  property  is 
included in accrued income and other assets on the Consolidated Balance Sheets.

Premises and Equipment

Premises  and  equipment  are  stated  at  cost,  less  accumulated  depreciation  and  amortization.  Depreciation,  computed 
using the straight-line method, is charged to occupancy expenses in the Consolidated Statements of Income over the estimated 
useful lives of the assets. Estimated useful lives are generally 3 years to 33 years for premises that the Corporation owns and 3 
years to 8 years for furniture and equipment. Leasehold improvements are generally amortized over the terms of their respective 
leases or 10 years, whichever is shorter.

Operating Leases

Operating leases with a term greater than one year are recognized as lease liabilities, measured as the present value of 
unpaid lease payments for operating leases where the Corporation is the lessee, and corresponding right-of-use (ROU) assets for 
the right to use the leased properties. Operating lease liabilities, recorded in accrued expenses and other liabilities, reflect the 
Corporation’s  obligation  to  make  future  lease  payments,  primarily  for  real  estate  locations.  Lease  terms  typically  comprise 
contractual terms but may include extension options reasonably certain of being exercised at lease inception for certain strategic 
locations such as regional headquarters. Payments are discounted using the Corporation's incremental borrowing rate, or the rate 
it would pay to borrow amounts equal to the lease payments over the lease term. The Corporation does not separate lease and 
non-lease  components  for  contracts  in  which  it  is  the  lessee.  ROU  assets,  recorded  in  accrued  income  and  other  assets,  are 
measured  based  on  lease  liabilities  adjusted  for  incentives  as  well  as  accrued  and  prepaid  rent.  Operating  lease  expense  is 
recognized on a straight-line basis over the lease term, while variable lease payments are recognized as incurred. Common area 
maintenance  and  other  executory  costs  are  the  main  components  of  variable  lease  payments.  Operating  and  variable  lease 
expenses are recorded in net occupancy expense on the Consolidated Statements of Income.

Software

Capitalized  software,  stated  at  cost  less  accumulated  amortization,  includes  purchased  software,  capitalizable 
application  development  costs  associated  with  internally  developed  software  and  cloud  computing  arrangements,  including 
capitalizable  implementation  costs  associated  with  hosting  arrangements  that  are  service  contracts.  Cloud  computing 
arrangements  include  software  as  a  service  (SaaS),  platform  as  a  service  (PaaS),  infrastructure  as  a  service  (IaaS)  and  other 
similar hosting arrangements. The Corporation primarily utilizes SaaS and IaaS arrangements. Capitalized implementation costs 
of  hosting  arrangements  that  are  service  contracts  were  $61  million  and  $43  million,  net  of  accumulated  depreciation  of 
$14 million and $5 million at December 31, 2023 and December 31, 2022, respectively. Depreciation expense related to these 
costs was $9 million and $4 million for the years ended December 31, 2023 and 2022, respectively.

F-53

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

Capitalized software is included in accrued income and other assets on the Consolidated Balance Sheets. Amortization 
expense,  generally  computed  on  the  straight-line  method,  is  charged  to  software  expense  in  the  Consolidated  Statements  of 
Income  over  the  estimated  useful  life  of  the  software,  generally  five  years,  or  the  term  of  the  hosting  arrangement  for 
implementation costs related to service contracts. 

Goodwill and Intangibles

Goodwill, included in accrued income and other assets on the Consolidated Balance Sheets, is initially recorded as the 
excess of the purchase price over the fair value of net assets acquired in a business combination and is subsequently evaluated at 
least  annually  for  impairment.  Goodwill  impairment  testing  is  performed  at  the  reporting  unit  level,  equivalent  to  a  business 
segment  or  one  level  below.  The  Corporation  has  three  reporting  units:  the  Commercial  Bank,  the  Retail  Bank  and  Wealth 
Management.

The Corporation performs its annual evaluation of goodwill impairment in the third quarter of each year and may elect 
to  perform  a  quantitative  impairment  analysis  or  first  conduct  a  qualitative  analysis  to  determine  if  a  quantitative  analysis  is 
necessary.  Additionally,  the  Corporation  evaluates  goodwill  impairment  on  an  interim  basis  if  events  or  changes  in 
circumstances between annual tests indicate additional testing may be warranted to determine if goodwill might be impaired. 
Factors considered in the assessment of the likelihood of impairment include macroeconomic conditions, industry and market 
considerations, stock performance of the Corporation and its peers, financial performance of the reporting units, and previous 
results  of  goodwill  impairment  tests,  amongst  other  factors.  Based  on  the  results  of  the  qualitative  analysis,  the  Corporation 
determines  whether  a  quantitative  test  is  necessary.  The  quantitative  test  compares  the  estimated  fair  value  of  identified 
reporting units with their carrying amount, including goodwill. If the estimated fair value of the reporting unit is less than the 
carrying value, an impairment charge would be recorded for the excess, not to exceed the amount of goodwill allocated to the 
reporting unit.

Intangibles are amortized on an accelerated basis, based on the estimated period the economic benefits are expected to 
be  received.  Intangibles  are  reviewed  for  impairment  when  events  or  changes  in  circumstances  indicate  that  their  carrying 
amounts may not be recoverable. Impairment for a finite-lived intangible asset exists if the sum of the undiscounted cash flows 
expected to result from the use of the asset exceeds its carrying value.

Additional information regarding goodwill and intangibles can be found in Note 7.

Nonmarketable Equity Securities

The  Corporation  has  certain  investments  that  are  not  readily  marketable.  These  investments  include  a  portfolio  of 
investments  in  indirect  private  equity  and  venture  capital  funds  and  restricted  equity  investments,  which  are  securities  the 
Corporation is required to hold for various reasons, primarily Federal Home Loan Bank of Dallas (FHLB) and Federal Reserve 
Bank (FRB) stock. These investments are accounted for on the cost or equity method and are included in accrued income and 
other assets on the Consolidated Balance Sheets. The investments are individually reviewed for impairment on a quarterly basis. 
Indirect private equity and venture capital funds are evaluated for impairment by comparing the carrying value to the estimated 
fair  value.  Impairment  is  charged  to  current  earnings  and  the  carrying  value  of  the  investment  is  written  down  accordingly. 
FHLB and FRB stock are recorded at cost (par value) and evaluated for impairment based on the ultimate recoverability of the 
par  value.  If  the  Corporation  does  not  expect  to  recover  the  full  par  value,  the  amount  by  which  the  par  value  exceeds  the 
ultimately recoverable value would be charged to current earnings and the carrying value of the investment would be written 
down accordingly.

Derivative Instruments and Hedging Activities

Derivative instruments are carried at fair value in either accrued income and other assets or accrued expenses and other 
liabilities on the Consolidated Balance Sheets. The accounting for changes in the fair value (i.e., gains or losses) of a derivative 
instrument is determined by whether it has been designated and qualifies as part of a hedging relationship and, further, by the 
type of hedging relationship. The Corporation presents derivative instruments at fair value on the Consolidated Balance Sheets 
on a net basis when a right of offset exists, based on transactions with a single counterparty and any cash collateral paid to and/
or received from that counterparty for derivative contracts that are subject to legally enforceable master netting arrangements.

For derivative instruments designated and qualifying as fair value hedges (i.e., hedging the exposure to changes in the 
fair value of an asset or a liability or an identified portion thereof that is attributable to a particular risk), the gain or loss on the 
derivative instrument, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk, are recognized in 
the same consolidated statement of income line that is used to present the earnings effect of the hedged item during the period 
of the change in fair values. For derivative instruments that are designated and qualify as cash flow hedges (i.e., hedging the 
exposure to variability in expected future cash flows that is attributable to a particular risk), the gain or loss on the derivative 

F-54

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

instrument is reported as a component of other comprehensive income and reclassified into earnings in the same consolidated 
statement of income line item as the earnings effect of the hedged item in the same period or periods during which the hedged 
transaction affects earnings. For derivative instruments not designated as hedging instruments, the gain or loss is recognized in 
risk management hedging (loss) income on the Consolidated Statements of Income during the period of change. The net change 
in derivatives is included in "other, net" operating activity within the Consolidated Statements of Cash Flows.

To qualify for the use of hedge accounting, a derivative must be effective at inception and expected to be continuously 
effective  in  offsetting  the  risk  being  hedged.  For  derivatives  designated  as  hedging  instruments  at  inception,  the  Corporation 
uses either the short-cut method or applies statistical regression analysis to assess effectiveness. The short-cut method is used 
for  $1.7  billion  of  notional  of  fair  value  hedges  of  medium-  and  long-term  debt.  This  method  allows  for  the  assumption  of 
perfect  effectiveness  and  eliminates  the  requirement  to  further  assess  hedge  effectiveness  on  these  transactions.  For  hedge 
relationships to which the Corporation does not apply the short-cut method, statistical regression analysis is used at inception to 
assess whether the derivative used is expected to be highly effective in offsetting changes in the fair value or cash flows of the 
hedged item. A statistical regression or qualitative analysis is performed at each reporting period thereafter to evaluate hedge 
effectiveness.  As  part  of  the  adoption  of  Topic  848,  certain  hedge  accounting  requirements  for  qualifying  modifications  to 
derivative  instruments  due  to  LIBOR  transition  were  suspended  through  the  completion  of  LIBOR  transition  in  third  quarter 
2023. For further information on Topic 848, refer to the "Loans" policy in this Note.

 Further information on the Corporation’s derivative instruments and hedging activities is included in Note 8.

Financial Guarantees

Certain guarantee contracts or indemnification agreements that contingently require the Corporation, as guarantor, to 
make payments to the guaranteed party are initially measured at fair value and included in accrued expenses and other liabilities 
on  the  Consolidated  Balance  Sheets.  The  subsequent  accounting  for  the  liability  depends  on  the  nature  of  the  underlying 
guarantee. The release from risk is accounted for under a particular guarantee when the guarantee expires or is settled, or by a 
systematic and rational amortization method.

Further information on the Corporation’s obligations under guarantees is included in Note 8.

Share-Based Compensation

The  Corporation  recognizes  share-based  compensation  expense  using  the  straight-line  method  over  the  requisite 
service  period,  generally  based  on  the  instruments'  grant-date  fair  value,  for  all  stock  awards,  including  those  with  graded 
vesting.  The  requisite  service  period  is  the  period  an  employee  is  required  to  provide  service  in  order  to  vest  in  the  award, 
which cannot extend beyond the date at which the employee is no longer required to perform any service to receive the share-
based compensation (i.e., the retirement-eligible date). Forfeiture of stock awards and dividend equivalents are accounted for as 
they occur.

Certain  awards  are  contingent  upon  performance  and/or  market  conditions,  which  affect  the  number  of  shares 
ultimately  issued.  The  Corporation  periodically  evaluates  the  probable  outcome  of  the  performance  conditions  and  makes 
cumulative adjustments to compensation expense as appropriate. Market conditions are included in the determination of the fair 
value  of  the  award  on  the  date  of  grant.  Subsequent  to  the  grant  date,  market  conditions  have  no  impact  on  the  amount  of 
compensation expense the Corporation will recognize over the life of the award.

Further information on the Corporation’s share-based compensation plans is included in Note 16.

Revenue Recognition

Revenue from contracts with customers comprises the noninterest income earned by the Corporation in exchange for 
services provided to customers and is recognized when services are completed or as they are rendered, although contracts are 
generally short-term by nature. Services provided over a period of time are typically transferred to customers evenly over the 
term  of  the  contracts  and  revenue  is  recognized  accordingly  over  the  period  services  are  provided.  Contract  receivables  are 
included in accrued income and other assets on the Consolidated Balance Sheets. Payment terms vary by services offered, and 
the time between completion of performance obligations and payment is typically not significant.

Card Fees

Card fees comprise interchange and other fee income earned on government card, commercial card, debit/automated 
teller machine card and merchant payment processing programs. Card fees are presented net of network costs, as performance 
obligations  for  card  services  are  limited  to  transaction  processing  and  settlement  with  the  card  network  on  behalf  of  the 
customers.  Fees  for  these  services  are  primarily  based  on  interchange  rates  set  by  the  network  and  transaction  volume.  The 
Corporation also provides ongoing card program support services, for which fees are based on contractually agreed-upon prices 
and customer demand for services.

Service Charges on Deposit Accounts

Service  charges  on  deposit  accounts  comprise  charges  on  retail  and  business  accounts,  including  fees  for  treasury 
management  services.  Treasury  management  services  include  transaction-based  services  related  to  payment  processing, 
overdrafts, non-sufficient funds and other deposit account activity, as well as account management services that are provided 
over time. Business customers can earn credits depending on deposit balances maintained with the Corporation, which may be 
used to offset fees. Fees and credits are based on predetermined, agreed-upon rates.

Fiduciary Income

Fiduciary  income  includes  fees  and  commissions  from  asset  management,  custody,  recordkeeping,  investment 
advisory  and  other  services  provided  primarily  to  personal  and  institutional  trust  customers.  Revenue  is  recognized  as  the 
services  are  performed  and  is  based  either  on  the  market  value  of  the  assets  managed  or  the  services  provided,  as  well  as 
agreed-upon rates.

Commercial Lending Fees

Commercial lending fees include both revenue from contracts with customers (primarily loan servicing fees) and other 
sources  of  revenue.  Commercial  loan  servicing  fees  are  based  on  contractually  agreed-upon  prices  and  timing  of  services 
provided.  Other  sources  of  revenue  in  commercial  lending  fees  primarily  include  fees  assessed  on  the  unused  portion  of 
commercial lines of credit (unused commitment fees).

Brokerage Fees

Brokerage  fees  include  commissions  earned  for  facilitating  securities  transactions  for  customers,  as  well  as  other 
brokerage services provided. Revenue is recognized when services are completed and is based on the type of services provided 
and  agreed-upon  rates.  The  Corporation  pays  commissions  based  on  brokerage  fee  revenue.  These  are  typically  recognized 
when  incurred  because  the  amortization  period  is  one  year  or  less  and  are  included  in  salaries  and  benefits  expense  on  the 
Consolidated  Statements  of  Income  As  of  November  2023,  brokerage  fees  include  income  from  sales  of  select  investment 
products  of  an  independent  financial  services  broker,  net  of  commissions  passed  through  to  employees  licensed  by  the 
independent broker to sell their products.

Other Revenues 

Other  revenues,  consisting  primarily  of  other  retail  fees,  investment  banking  fees  and  insurance  commissions,  are 
typically recognized when services or transactions are completed and are based on the type of services provided and agreed-
upon rates.

Except as discussed above, commissions and other incentives paid to employees are generally based on several internal 

and external metrics and, as a result, are not solely dependent on revenue generating activities.

Defined Benefit Pension and Other Postretirement Costs

Defined benefit pension costs are funded consistent with the requirements of federal laws and regulations. Inherent in 
the  determination  of  defined  benefit  pension  costs  are  assumptions  concerning  future  events  that  will  affect  the  amount  and 
timing  of  required  benefit  payments  under  the  plans.  These  include  demographic  assumptions  such  as  retirement  age  and 
mortality,  a  compensation  rate  increase,  a  discount  rate  used  to  determine  the  current  benefit  obligation,  form  of  payment 
election and a long-term expected rate of return on plan assets. Net periodic defined benefit pension expense includes service 
cost, interest cost based on the assumed discount rate, an expected return on plan assets based on an actuarially derived market-
related value of assets (MRVA), amortization of prior service cost or credit and amortization of net actuarial gains or losses. 
The  MRVA  for  fixed  income  securities  and  private  placement  assets  is  based  on  the  fair  value  of  plan  assets,  whereas  the 
MRVA for other plan assets is determined by amortizing the current year’s investment gains and losses (the actual investment 
return net of the expected investment return) over 5 years. The amortization adjustment cannot exceed 10 percent of the fair 
value of assets. Prior service costs or credits include the impact of plan amendments on the liabilities and are amortized over the 
future service periods of active employees expected to receive benefits under the plan. Actuarial gains and losses result from 
experience different from that assumed and from changes in assumptions (excluding asset gains and losses not yet reflected in 
market-related  value).  Amortization  of  actuarial  gains  and  losses  is  included  as  a  component  of  net  periodic  defined  benefit 
pension cost for a year if the actuarial net gain or loss exceeds 10 percent of the greater of the projected benefit obligation or the 
market-related  value  of  plan  assets.  If  amortization  is  required,  the  excess  is  amortized  over  the  average  remaining  service 
period of participating employees expected to receive benefits under the plan. Service costs are included in salaries and benefits 
expense, while the other components of net periodic defined benefit pension expense are included in other noninterest expenses 
on the Consolidated Statements of Income.

Postretirement benefit costs includes service cost, interest cost based on the assumed discount rate, an expected return 
on  plan  assets  based  on  an  actuarially  derived  MRVA,  amortization  of  prior  service  cost  or  credit  and  amortization  of  net 
actuarial gains or losses. The components of postretirement benefit costs follow similar policies and methodologies as defined 
benefit pensions costs. Postretirement benefits are recognized in other noninterest expenses on the Consolidated Statements of 
Income.

See  Note  17  for  further  information  regarding  the  Corporation’s  defined  benefit  pension  and  other  postretirement 

plans.

Income Taxes

The provision for income taxes is the sum of income taxes due for the current year and deferred taxes. The Corporation 
classifies interest and penalties on income tax liabilities and excess tax benefits and deficiencies resulting from employee stock 
awards in the provision for income taxes on the Consolidated Statements of Income.

Deferred taxes arise from temporary differences between the income tax basis and financial accounting basis of assets 
and  liabilities.  Deferred  tax  assets  are  evaluated  for  realization  based  on  available  evidence  of  projected  future  reversals  of 
existing  taxable  temporary  differences,  foreign  tax  credit  limitations,  assumptions  made  regarding  future  events  and,  when 
applicable, state loss carryback capacity. A valuation allowance is provided when it is more likely than not that some portion of 
the deferred tax asset will not be realized.

Earnings Per Share

Basic  net  income  per  common  share  is  calculated  using  the  two-class  method.  The  two-class  method  is  an  earnings 
allocation formula that determines earnings per share for each share of common stock and participating securities according to 
dividends  declared  (distributed  earnings)  and  participation  rights  in  undistributed  earnings.  Distributed  and  undistributed 
earnings  are  allocated  between  common  and  participating  security  shareholders  based  on  their  respective  rights  to  receive 
dividends. Nonvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents are 
considered participating securities (e.g., certain service-based restricted stock units). Undistributed net losses are not allocated 
to nonvested restricted shareholders, as these shareholders do not have a contractual obligation to fund the losses incurred by 
the Corporation. Net income attributable to common shares is then divided by the weighted-average number of common shares 
outstanding during the period.

Diluted net income per common share is calculated using the more dilutive of either the treasury method or the two-
class  method.  The  dilutive  calculation  considers  common  stock  issuable  under  the  assumed  exercise  of  stock  options  and 
warrants, as well as service- and performance-based restricted stock units granted under the Corporation’s stock plans using the 
treasury stock method, if dilutive. Net income attributable to common shares is then divided by the total of weighted-average 
number of common shares and common stock equivalents outstanding during the period.

Statements of Cash Flows

Cash  and  cash  equivalents  are  defined  as  those  amounts  included  in  cash  and  due  from  banks  and  interest-bearing 

deposits with banks on the Consolidated Balance Sheets. 

Comprehensive Income (Loss)

The Corporation presents on an annual basis the components of net income and other comprehensive income in two 
separate,  but  consecutive  statements  and  presents  on  an  interim  basis  the  components  of  net  income  and  a  total  for 
comprehensive income in one continuous consolidated statement of comprehensive income. 

Recently Issued Accounting Pronouncements

In  March  2023,  the  FASB  issued  ASU  No.  2023-02  "Investments-Equity  Method  and  Joint  Ventures  (Topic  323): 
Accounting  for  Investments  in  Tax  Credit  Structures  Using  the  Proportional  Amortization  Method  (a  consensus  of  the 
Emerging  Issues  Task  Force)"  (ASU  2023-02).  ASU  2023-02  expands  the  permitted  use  of  the  proportional  amortization 
method,  which  is  currently  only  available  to  low-income  housing  tax  credit  investments,  to  other  tax  equity  investments  if 
certain  conditions  are  met.  Under  the  proportional  amortization  method,  the  initial  cost  of  an  investment  is  amortized  in 
proportion to the income tax benefits received and both the amortization of the investment and the income tax benefits received 
are recognized as a component of income tax expense. The Corporation adopted this ASU on January 1, 2024 by applying the 
modified retrospective basis of transition or, for certain changes, a prospective basis. The update did not have a material impact 
on their financial statements.

In November 2023, the FASB issued ASU No. 2023-07 "Segment Reporting (Topic 280): Improvements to Reportable 
Segment Disclosures" (ASU 2023-07). The update requires enhanced disclosures about significant segment expenses, enhanced 
interim disclosure requirements, clarification for when multiple segment measures of profit or loss can be disclosed, and other 
requirements  intended  to  improve  overall  reportable  segment  disclosures  in  annual  and  interim  periods.  ASU  2023-07  is 
effective for the Corporation in the annual period beginning on January 1, 2024 and interim periods beginning on January 1, 
2025 with retrospective application to all prior periods presented. Early adoption is permitted. The Corporation is evaluating the 
impact of ASU 2023-07 on its reportable segment disclosures. 

In  December  2023,  the  FASB  issued  ASU  No.  2023-09  "Income  Taxes  (Topic  740):  Improvements  to  Income  Tax 
Disclosures"  (ASU  2023-09).  ASU  2023-09  requires  additional  annual  disclosures  including  further  disaggregation  of 
information  in  the  rate  reconciliation,  additional  information  for  reconciling  items  meeting  a  quantitative  threshold,  further 
disaggregation of income taxes paid, and other required disclosures. ASU 2023-09 is effective for the Corporation in the annual 
period beginning on January 1, 2025 and applied on a prospective basis with both early adoption and retrospective application 
permitted. The Corporation is evaluating the impact of ASU 2023-09 on its income tax disclosures.

Assets and Liabilities Recorded at Fair Value on a Nonrecurring Basis

The Corporation may be required to record certain assets and liabilities at fair value on a nonrecurring basis. These 
include assets that are recorded at the lower of cost or fair value, and were recognized at fair value since it was less than cost at 
the end of the period.

The following table presents assets recorded at fair value on a nonrecurring basis at December 31, 2023 and 2022. No

Level 3 assets recorded at fair value on a nonrecurring basis at December 31, 2023 and December 31, 2022 included 
loans with a specific allowance and certain bank property held for sale, both measured based on the fair value of collateral. The 
unobservable inputs were the additional adjustments applied by management to the appraised values to reflect such factors as 
non-current appraisals and revisions to estimated time to sell. These adjustments are determined based on qualitative judgments 
made by management on a case-by-case basis and are not observable inputs, although they are used in the determination of fair 
value.  At  December  31,  2023,  loans  held-for-sale  classified  as  Level  3  represented  loans  held-for-sale  in  less  liquid  markets 
requiring significant management assumptions when determining fair value.

Estimated Fair Values of Financial Instruments Not Recorded at Fair Value on a Recurring Basis

The  Corporation  typically  holds  the  majority  of  its  financial  instruments  until  maturity  and  thus  does  not  expect  to 
realize  many  of  the  estimated  fair  value  amounts  disclosed.  The  disclosures  do  not  include  estimated  fair  value  amounts  for 
items that are not defined as financial instruments, but which have significant value. These include such items as core deposit 
intangibles,  the  future  earnings  potential  of  significant  customer  relationships  and  the  value  of  trust  operations  and  other  fee 
generating businesses. The Corporation believes the imprecision of an estimate could be significant. The disclosures also do not 
include a limited amount of nonmarketable equity securities (primarily indirect private equity and venture capital investments)

Issued and/or guaranteed by U.S. government agencies or U.S. government-sponsored enterprises.

Unrealized losses on investment securities resulted from changes in market interest rates. The Corporation’s portfolio 
is comprised of securities issued or guaranteed by the U.S. government agencies or government-sponsored enterprises. As such, 
it  is  expected  that  the  securities  would  not  be  settled  at  a  price  less  than  the  amortized  cost  of  the  investments.  Further,  the 
Corporation  does  not  intend  to  sell  the  investments,  and  it  is  not  more-likely-than-not  that  it  will  be  required  to  sell  the 
investments before recovery of amortized costs. No allowance for credit losses was recorded on securities in an unrealized loss 
position at December 31, 2023 or December 31, 2022.

Interest  receivable  on  investment  securities  totaled  $40  million  and  $49  million  at  December  31,  2023  and  2022, 

respectively, and was included in accrued income and other assets on the Consolidated Balance Sheets.

Sales,  calls  and  write-downs  of  investment  securities  available-for-sale,  computed  based  on  the  adjusted  cost  of  the 

specific security, resulted in no gains or losses during the years ended December 31, 2023, 2022 and 2021.

The  following  table  summarizes  the  amortized  cost  and  fair  values  of  investment  securities  by  contractual  maturity. 
Securities with multiple maturity dates are classified in the period of final maturity. The actual cash flows of mortgage-backed 
securities  may  differ  as  borrowers  of  the  underlying  loans  may  exercise  prepayment  options.  Expected  maturities  will  differ 
from  contractual  maturities  because  borrowers  may  have  the  right  to  call  or  prepay  obligations  with  or  without  call  or 
prepayment penalties.

Includes all loans not included in the categories of special mention, substandard or nonaccrual.
Includes loans with an internal rating of special mention, substandard loans for which the accrual of interest has not been discontinued 
and nonaccrual loans. Special mention loans have potential credit weaknesses that deserve management’s close attention, such as loans 
to borrowers who may be experiencing financial difficulties that may result in deterioration of repayment prospects from the borrower at 
some future date. Accruing substandard loans have a well-defined weakness, or weaknesses, such as loans to borrowers who may be 
experiencing losses from operations or inadequate liquidity of a degree and duration that jeopardizes the orderly repayment of the loan. 
Substandard  loans  are  also  distinguished  by  the  distinct  possibility  of  loss  in  the  future  if  these  weaknesses  are  not  corrected. 
Nonaccrual  loans  are  loans  for  which  the  accrual  of  interest  has  been  discontinued.  For  further  information  regarding  nonaccrual 
loans, refer to the Nonperforming Assets subheading in Note 1 - Basis of Presentation and Accounting Policies. These categories are 
generally  consistent  with  the  "special  mention"  and  "substandard"  categories  as  defined  by  regulatory  authorities.  A  minority  of 
nonaccrual loans are consistent with the "doubtful" category.

Loan interest receivable totaled $313 million and $261 million at December 31, 2023 and 2022, respectively, and was 

included in accrued income and other assets on the Consolidated Balance Sheets.

Loan Modifications Made to Borrowers Experiencing Financial Difficulty 

Effective January 1, 2023, the Corporation adopted the provisions of ASU 2022-02, which eliminated the accounting 
for TDRs while expanding loan modification and vintage disclosure requirements. The update specifically required additional 
disclosures on loan modifications to borrowers experiencing financial difficulties that involved an interest rate reduction, other-
than-insignificant payment delay, a term extension, principal forgiveness or a combination thereof.

The following table displays the amortized cost basis at December 31, 2023 of loan modifications made to borrowers 

experiencing financial difficulty that were restructured during the year ended December 31, 2023 by type of modification.

During  the  year  ended  December  31,  2023,  modifications  to  borrowers  experiencing  financial  difficulty  included 

restructurings with other-than-insignificant payment delays of $6 million in the Commercial loan category.

On an ongoing basis, the Corporation monitors the performance of modified loans related to their restructured terms. 
Loans restructured during the year ended December 31, 2023 were current under modified terms at year ended December 31, 
2023. Nonperforming restructured loans are classified as nonaccrual loans and are individually evaluated in the allowance for 
loan losses.

For restructured loans, a subsequent payment default is defined in terms of delinquency, when a principal or interest 

payment is 90 days past due or classified into nonaccrual status during the reporting period. Of the loans restructured during the 
12 month period ended December 31, 2023, there were no subsequent defaults as of December 31, 2023.

modifications involved forgiveness of principal. There were no significant commitments to lend additional funds to borrowers 
whose terms have been modified in TDRs at December 31, 2022.

For principal deferrals, incremental deterioration in the credit quality of the loan, represented by a downgrade in the 
risk  rating  of  the  loan,  for  example,  due  to  missed  interest  payments  or  a  reduction  of  collateral  value,  was  considered  a 
subsequent  default.  For  interest  rate  reductions,  a  subsequent  payment  default  was  defined  in  terms  of  delinquency,  when  a 
principal  or  interest  payment  was  90  days  past  due.  Of  the  TDRs  modified  during  the  year  ended  December  31,  2022,  there 
were $6 million of subsequent defaults of principal deferrals and no subsequent defaults of interest rate reductions. 

NOTE 5 - SIGNIFICANT GROUP CONCENTRATIONS OF CREDIT RISK

Concentrations of credit risk may exist when a number of borrowers are engaged in similar activities, or activities in 
the  same  geographic  region,  and  have  similar  economic  characteristics  that  would  cause  them  to  be  similarly  impacted  by 
changes  in  economic  or  other  conditions.  Concentrations  of  both  on-balance  sheet  and  off-balance  sheet  credit  risk  are 
controlled  and  monitored  as  part  of  credit  policies.  The  Corporation  is  a  regional  financial  services  holding  company  with  a 
geographic concentration of its on-balance-sheet and off-balance-sheet activities in Michigan, California and Texas.

The Corporation performs its annual evaluation of goodwill impairment in the third quarter of each year and may elect 
to  perform  a  quantitative  impairment  analysis  or  first  conduct  a  qualitative  analysis  to  determine  if  a  quantitative  analysis  is 
necessary. In addition, the Corporation evaluates goodwill impairment on an interim basis if events or changes in circumstances 
between annual tests indicate additional testing may be warranted to determine if goodwill might be impaired.

In 2023 and 2022, the annual test of goodwill impairment was performed as of the beginning of the third quarter, and 
in  both  periods,  a  qualitative  assessment  resulted  in  the  Corporation  determining  goodwill  was  not  impaired,  as  it  was  more 
likely than not that the fair value of each reporting unit exceeded its carrying value. 

NOTE 8 - DERIVATIVE AND CREDIT-RELATED FINANCIAL INSTRUMENTS

In  the  normal  course  of  business,  the  Corporation  enters  into  various  transactions  involving  derivative  and  credit-
related financial instruments to manage exposure to fluctuations in interest rate, foreign currency and other market risks and to 
meet the financing needs of customers (customer-initiated derivatives). These financial instruments involve, to varying degrees, 
elements of market and credit risk. Market and credit risk are included in the determination of fair value.

Market risk is the potential loss that may result from movements in interest rates, foreign currency exchange rates or 
energy commodity prices that cause an unfavorable change in the value of a financial instrument. The Corporation manages this 
risk by establishing monetary exposure limits and monitoring compliance with those limits. Market risk inherent in interest rate 
and  energy  contracts  entered  into  on  behalf  of  customers  is  mitigated  by  taking  offsetting  positions,  except  in  those 
circumstances  when  the  amount,  tenor  and/or  contract  rate  level  results  in  negligible  economic  risk,  whereby  the  cost  of 
purchasing an offsetting contract is not economically justifiable. The Corporation mitigates most of the inherent market risk in 
foreign  exchange  contracts  entered  into  on  behalf  of  customers  by  taking  offsetting  positions  and  manages  the  remainder 
through individual foreign currency position limits and aggregate value-at-risk limits. These limits are established annually and 
positions are monitored quarterly. Market risk inherent in derivative instruments held or issued for risk management purposes is 
typically offset by changes in the fair value of the assets or liabilities being hedged.

Credit  risk  is  the  possible  loss  that  may  occur  in  the  event  of  nonperformance  by  the  counterparty  to  a  financial 
instrument.  The  Corporation  attempts  to  minimize  credit  risk  arising  from  customer-initiated  derivatives  by  evaluating  the 
creditworthiness  of  each  customer,  adhering  to  the  same  credit  approval  process  used  for  traditional  lending  activities  and 
obtaining collateral as deemed necessary. Derivatives with dealer counterparties are either cleared through a clearinghouse or 
settled directly with a single counterparty. For derivatives  settled  directly  with  dealer  counterparties, the  Corporation utilizes 
counterparty risk limits and monitoring procedures as well as master netting arrangements and bilateral collateral agreements to 
facilitate the management of credit risk.

Included in the fair value of derivative instruments are credit valuation adjustments reflecting counterparty credit risk. 
These  adjustments  are  determined  by  applying  a  credit  spread  for  the  counterparty  or  the  Corporation,  as  appropriate,  to  the 
total  expected  exposure  of  the  derivative.  Master  netting  arrangements  effectively  reduce  credit  valuation  adjustments  by 
permitting  settlement  of  positive  and  negative  positions  and  offset  cash  collateral  held  with  the  same  counterparty  on  a  net 
basis. Bilateral collateral agreements require daily exchange of cash or highly rated securities issued by the U.S. Treasury or 
other U.S. government entities to collateralize amounts due to either party. At December 31, 2023, counterparties with bilateral 
collateral agreements deposited $143 million of cash with the Corporation to secure the fair value of contracts in an unrealized 
gain position, and the Corporation had pledged $4 million of marketable investment securities and posted $14 million of cash as 
collateral for contracts in an unrealized loss position. For those counterparties not covered under bilateral collateral agreements, 
collateral  is  obtained,  if  deemed  necessary,  based  on  the  results  of  management’s  credit  evaluation  of  the  counterparty. 
Collateral varies, but may include cash, investment securities, accounts receivable, equipment or real estate.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Derivative Instruments

Derivative instruments utilized by the Corporation are negotiated over-the-counter and primarily include swaps, caps 
and  floors,  forward  contracts  and  options,  each  of  which  may  relate  to  interest  rates,  energy  commodity  prices  or  foreign 
currency exchange rates. Swaps are agreements in which two parties periodically exchange cash payments based on specified 
indices applied to a specified notional amount until a stated maturity. Caps and floors are agreements which entitle the buyer to 
receive cash payments based on the  difference  between  a specified  reference rate  or  price  and an  agreed strike  rate  or price, 
applied to a specified notional amount until a stated maturity. Forward contracts are over-the-counter agreements to buy or sell 
an asset at a specified future date and price. Options are similar to forward contracts except the purchaser has the right, but not 
the obligation, to buy or sell the asset during a specified period or at a specified future date.

Over-the-counter  contracts  are  tailored  to  meet  the  needs  of  the  counterparties  involved  and,  therefore,  contain  a 
greater  degree  of  credit  risk  and  liquidity  risk  than  exchange-traded  contracts,  which  have  standardized  terms  and  readily 
available price information. The Corporation reduces exposure to market and liquidity risks from over-the-counter derivative 
instruments entered into for risk management purposes, and transactions entered into to mitigate the market risk associated with 
customer-initiated transactions, by taking offsetting positions with investment grade domestic and foreign financial institutions 
and subjecting counterparties to credit approvals, limits and collateral monitoring procedures similar to those used in making 
other extensions of credit. In addition, certain derivative contracts executed bilaterally with a dealer counterparty in the over-
the-counter market are cleared through a clearinghouse, whereby the clearinghouse becomes the counterparty to the transaction.

The Corporation's derivative instruments used for managing interest rate risk include cash flow hedging strategies that 
convert variable-rate loans to fixed rates and fair value hedging strategies that convert fixed-rate medium-and long-term debt to 
variable  rates.  Interest  and  fees  on  loans  included  (expense)  income  related  to  swaps  settlements  of  $(602)  million,  $(25)

De-designated Interest Rate Swaps and Price Alignment Income

On November 15, 2023, the Bloomberg Index Services Limited announced a permanent cessation of BSBY and all of 
its  tenors  effective  November  15,  2024.  Accordingly,  the  Corporation  de-designated  $7.0  billion  of  interest  rate  swaps 
accounted for as cash flow hedges of BSBY-indexed loans, as of November 15, 2023, because it was no longer probable that 
the BSBY-based loan cash flows would occur through the duration of the hedging relationships. 

As a result of the de-designation, a pre-tax loss of $195 million was reclassified out of AOCI and into earnings for 
cash flows no longer probable of occurring. In addition, periodic settlement losses of $29 million and fair market value gains of 
$133  million  for  de-designated  positions  were  recognized  as  part  of  noninterest  income  from  the  de-designation  date  of 
November  15,  2023  through  December  31,  2023.  This  resulted  in  a  net  loss  of  $91  million  recorded  as  a  component  of  risk 
management hedging (loss) income in the Consolidated Statement of Income.

F-76

 
 
 
 
 
 
 
 
 
 
 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

Amounts in AOCI related to cash flows that continue to be probable of occurring are amortized out of AOCI and into 
earnings from the de-designation date through BSBY cessation, resulting in a pre-tax loss of $26 million recognized as part of 
interest and fees on loans as of December 31, 2023. Along with settlements no longer recognized through margin, this resulted 
in a net benefit of $3 million to interest and fees on loans for the year ended December 31, 2023.

For more information on accumulated net losses on cash flow hedges, refer to Note 14.

Risk management hedging (loss) income also includes price alignment income, which is income received on payments 
made to a central clearing party for centrally cleared derivatives. Positions are settled daily based on derivative fair values and 
the  party  receiving  net  settlement  amounts  pays  price  alignment,  based  on  an  earning  rate,  to  the  party  making  settlement 
payments. Price alignment income totaled $51 million for the year ending December 31, 2023, $8 million for the year ending 
December 31, 2022 and was insignificant for the year ending December 31, 2021. 

Customer-Initiated and Other

The Corporation enters into derivative transactions at the request of customers and generally takes offsetting positions 
with dealer counterparties to mitigate the inherent market risk. Income primarily results from the spread between the customer 
derivative and the offsetting dealer position.

For  customer-initiated  foreign  exchange  contracts  where  offsetting  positions  have  not  been  taken,  the  Corporation 
manages  the  remaining  inherent  market  risk  through  individual  foreign  currency  position  limits  and  aggregate  value-at-risk 
limits. These limits are established annually and reviewed quarterly. 

Fair values of customer-initiated and other derivative instruments represent the net unrealized gains or losses on such 
contracts  and  are  recorded  on  the  Consolidated  Balance  Sheets.  Changes  in  fair  value  are  recognized  on  the  Consolidated 
Statements of Income. The net gains recognized in income on customer-initiated derivative instruments, net of the impact of 
offsetting positions included in derivative income, were as follows:

The  Corporation  maintains  an  allowance  to  cover  current  expected  credit  losses  inherent  in  lending-related 
commitments,  including  unused  commitments  to  extend  credit,  letters  of  credit  and  financial  guarantees.  The  allowance  for 
credit losses on lending-related commitments, included in accrued expenses and other liabilities on the Consolidated Balance 
Sheets, was $40 million and $51 million at December 31, 2023 and 2022, respectively.

Unused Commitments to Extend Credit

Commitments to extend credit are legally binding agreements to lend to a customer, provided there is no violation of 
any condition established in the contract. These commitments generally have fixed expiration dates or other termination clauses 
and may require payment of a fee. Since many commitments expire without being drawn upon, the total contractual amount of 
commitments  does  not  necessarily  represent  future  cash  requirements  of  the  Corporation.  Commercial  and  other  unused 
commitments  are  primarily  variable  rate  commitments.  The  allowance  for  credit  losses  on  lending-related  commitments

included $38 million and $44 million at December 31, 2023 and 2022, respectively, for expected credit losses inherent in the 
Corporation’s unused commitments to extend credit.

Standby and Commercial Letters of Credit

Standby  letters  of  credit  represent  conditional  obligations  of  the  Corporation  which  guarantee  the  performance  of  a 
customer to a third party. Standby letters of credit are primarily issued to support public and private borrowing arrangements, 
including commercial paper, bond financing and similar transactions. Commercial letters of credit are issued to finance foreign 
or domestic trade transactions. These contracts expire in decreasing amounts through the year 2033. The Corporation may enter 
into participation arrangements with third parties that effectively reduce the maximum amount of future payments which may 
be required under standby and commercial letters of credit. These risk participations covered $85 million and $107 million at 
December  31,  2023  and  2022,  respectively,  of  the  $3.6  billion  and  $3.8  billion  of  standby  and  commercial  letters  of  credit 
outstanding at December 31, 2023 and 2022, respectively.

other  liabilities  on  the  Consolidated  Balance  Sheets,  totaled  $34  million  at  December  31,  2023,  including  $32  million  in 
deferred  fees  and  $2  million  in  the  allowance  for  credit  losses  on  lending-related  commitments.  At  December  31,  2022,  the 
comparable amounts were $35 million, $28 million and $7 million, respectively.

The following table presents a summary of criticized standby and commercial letters of credit at December 31, 2023 
and 2022. The Corporation's criticized list is consistent with the Special Mention, Substandard and Doubtful categories defined 
by regulatory authorities. The Corporation manages credit risk through underwriting, periodically reviewing and approving its 
credit exposures using Board committee approved credit policies and guidelines.

Other Credit-Related Financial Instruments

The Corporation enters into credit risk participation agreements, under which the Corporation assumes credit exposure 
associated with a borrower’s performance related to certain interest rate derivative contracts. The Corporation is not a party to 
the  interest  rate  derivative  contracts  and  only  enters  into  these  credit  risk  participation  agreements  in  instances  in  which  the 
Corporation is also a party to the related loan participation agreement for such borrowers. The Corporation manages its credit 
risk  on  the  credit  risk  participation  agreements  by  monitoring  the  creditworthiness  of  the  borrowers,  which  is  based  on  the 
normal credit review process as if the Corporation had entered into the derivative instruments directly with the borrower. The 
notional amount of such credit risk participation agreements reflects the pro-rata share of the derivative instrument, consistent 
with  its  share  of  the  related  participated  loan.  The  total  notional  amount  of  the  credit  risk  participation  agreements  was 
approximately $1.0 billion and $951 million at December 31, 2023 and 2022, respectively, and the fair value was insignificant 
at both December 31, 2023 and December 31, 2022. The maximum estimated exposure to these agreements, as measured by 
projecting a maximum value of the guaranteed derivative instruments as of the balance sheet date, assuming 100 percent default 
by all obligors on the maximum values, was $2 million at December 31, 2023 and insignificant at December 31, 2022. In the 
event  of  default,  the  lead  bank  has  the  ability  to  liquidate  the  assets  of  the  borrower,  in  which  case  the  lead  bank  would  be 
required  to  return  a  percentage  of  the  recouped  assets  to  the  participating  banks.  As  of  December  31,  2023,  the  weighted 
average remaining maturity of outstanding credit risk participation agreements was 4.1 years.

In 2008, the Corporation sold its remaining ownership of Visa Class B shares and entered into a derivative contract. 
Under the terms of the derivative contract, the Corporation will compensate the counterparty primarily for dilutive adjustments 
made to the conversion factor of the Visa Class B shares to Class A shares based on the ultimate outcome of litigation involving 
Visa. Conversely, the Corporation will be compensated by the counterparty for any increase in the conversion factor from anti- 
dilutive  adjustments.  The  notional  amount  of  the  derivative  contract  was  equivalent  to  approximately  780,000  Visa  Class  B 
Shares. The fair value of the derivative liability, included in accrued expenses and other liabilities on the Consolidated Balance 
Sheets, was $12 million at both December 31, 2023 and 2022.

NOTE 9 - VARIABLE INTEREST ENTITIES (VIEs)

The Corporation evaluates its interest in certain entities to determine if these entities meet the definition of a VIE and 
whether the Corporation is the primary beneficiary and should consolidate the entity based on the variable interests it held both 
at inception and when there is a change in circumstances that requires a reconsideration.

The Corporation holds ownership interests in funds in the form of limited partnerships or limited liability companies 
(LLCs) investing in affordable housing projects that qualify for the low-income housing tax credit (LIHTC). The Corporation 

F-78

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

also directly invests in limited partnerships and LLCs which invest in community development projects, which generate similar 
tax  credits  to  investors  (other  tax  credit  entities).  As  an  investor,  the  Corporation  obtains  income  tax  credits  and  deductions 
from  the  operating  losses  of  these  tax  credit  entities.  These  tax  credit  entities  meet  the  definition  of  a  VIE;  however,  the 
Corporation is not the primary beneficiary of the entities, as the general partner or the managing member has both the power to 
direct the activities that most significantly impact the economic performance of the entities and the obligation to absorb losses 
or the right to receive benefits that could be significant to the entities.

The Corporation accounts for its interests in LIHTC entities using the proportional amortization method. Ownership 
interests in other tax credit entities are accounted for under either the cost or equity method. Exposure to loss as a result of the 
Corporation’s involvement in LIHTC entities and other tax credit entities at December 31, 2023 was limited to $500 million 
and $29 million, respectively. 

Investment  balances,  including  all  legally  binding  commitments  to  fund  future  investments,  are  included  in  accrued 
income and other assets on the Consolidated Balance Sheets. A liability is recognized in accrued expenses and other liabilities 
on the Consolidated Balance Sheets for all legally binding unfunded commitments to fund tax credit entities ($231 million at 
December 31, 2023). Amortization and other write-downs of LIHTC investments are presented on a net basis as a component 
of the provision for income taxes on the Consolidated Statements of Income, while amortization and write-downs of other tax 
credit investments are recorded in other noninterest income. The income tax credits and deductions are recorded as a reduction 
of income tax expense and a reduction of federal income taxes payable.

The Corporation provided no financial or other support that was not contractually required to any of the above VIEs 

during the years ended December 31, 2023, 2022 and 2021.

The following table summarizes the impact of these tax credit entities on the Corporation’s Consolidated Statements of 

Income.

NOTE 11 - SHORT-TERM BORROWINGS

Federal  funds  purchased  generally  mature  within  one  to  four  days  from  the  transaction  date.  Other  short-term 
borrowings, which may consist of borrowed securities and short-term notes, generally mature within one to 120 days from the 
transaction date. At December 31, 2023 and 2022, other short-term borrowings primarily consisted of advances from the FHLB 
of Dallas, Texas, which provides short- and long-term funding to its members through advances collateralized by real estate-
related loans, certain government agency-backed securities and other eligible assets. Actual borrowing capacity is contingent on 
the amount of collateral pledged to the FHLB. At December 31, 2023, the Bank had pledged real estate-related loans totaling 
$21.9  billion  and  investment  securities  totaling  $6.6  billion  to  the  FHLB,  which  provided  for  up  to  $17.1  billion  of 
collateralized  borrowing  with  the  FHLB.  Of  the  $17.1  billion  total  capacity  at  FHLB  at  December  31,  2023,  $3.6  billion  in 
short-term advances and $4.0 billion in medium- and long-term advances were outstanding, leaving $9.5 billion available at the 
FHLB at December 31, 2023.

At  December  31,  2023,  the  Bank  had  pledged  loans  totaling  $24.6  billion  and  investment  securities  totaling  $7.7 
billion  to  the  FRB,  which  provided  for  up  to  $21.0  billion  and  $9.3  billion  of  collateralized  borrowing  through  the  discount 
window and BTFP program, respectively. The Bank did not rely on the BTFP facility as a funding source, except to perform an 
operational test at the onset, and does not plan to use the facility for the remainder of its existence. Total available collateralized 
borrowings with the FRB was $30.3 billion at December 31, 2023.

(a) The  fixed  interest  rates  on  these  notes  have  been  swapped  to  a  variable  rate  and  designated  in  a  hedging  relationship.  Accordingly, 

carrying value has been adjusted to reflect the change in the fair value of the debt as a result of changes in the benchmark rate.

Subordinated notes with remaining maturities greater than one year qualify as Tier 2 capital. 

In  first  quarter  2023,  the  Bank  borrowed  $4.0  billion  of  fixed-rate  FHLB  advances  due  between  2025  and  2028. 
Interest  is  due  monthly,  with  principal  due  at  maturity.  Additionally,  the  Bank  entered  into  fair  value  fixed-to-floating  rate 
swaps in which the Bank received a weighted-average fixed rate of 3.79% and pays a floating rate based on SOFR. See Note 11 
- Short-Term Borrowings for additional information about FHLB advances. 

In January 2024, the Corporation issued $1.0 billion of fixed-to-floating rate senior notes due in 2030, with a rate of 
5.982% for the first five years. The rate on the senior notes will reset on January 30, 2029 to SOFR plus 215.5 basis points until 
called  or  matured.  Additionally,  the  Corporation  entered  into  two  fair  value  fixed-to-floating  rate  swaps  in  which  the 
Corporation received a weighted average fixed rate of 3.77% and will pay a floating rate based on SOFR for the first five years.

Unamortized debt issuance costs deducted from the carrying amount of medium- and long-term debt totaled $6 million 

and $9 million at December 31, 2023 and 2022, respectively.

NOTE 13 - SHAREHOLDERS’ EQUITY

 In 2022 and 2021, repurchases of common stock under the share repurchase program initially authorized in 2010 by 
the  Board  of  Directors  of  the  Corporation  totaled  377  thousand  shares  at  an  average  price  paid  of  $92.61  per  share  and 
9.5 million shares at an average price paid of $75.82 per share, respectively. There were no repurchases of common stock under 
the share repurchase program in 2023. There is no expiration date for the share repurchase program. 

At December 31, 2023, the Corporation had 4.3 million shares of common stock reserved for stock option exercises 

and restricted stock unit vesting.

In  May  2020,  the  Corporation  issued  and  sold  400,000  depositary  shares,  each  representing  a  1/100th  ownership 
interest in a share of 5.625% Fixed-Rate Reset Non-Cumulative Perpetual Preferred Stock, Series A, without par value, with a 
liquidation preference of $100,000 per share (equivalent of 1,000 per depositary share). Holders of the depositary shares will be 
entitled to all proportional rights and preferences of the Series A preferred stock (including dividend, voting, redemption and 
liquidation  rights).  The  $400  million  issuance  yielded  $394  million  in  proceeds  net  of  underwriting  discounts  and  offering 
expenses. Dividends on the Series A preferred stock accrue on a non-cumulative basis and are payable in arrears when, as and if 
authorized  by  the  Corporation’s  Board  of  Directors  or  a  duly  authorized  committee  of  the  Board  and  declared  by  the 
Corporation, on the first day of January, April, July and October of each year, and commenced on October 1, 2020. Under the 
terms of the Series A preferred stock, the ability of the Corporation to pay dividends on, make distributions with respect to, or 
to repurchase, redeem or acquire its common stock or any other stock ranking on parity with or junior to the Series A preferred 
stock, is subject to restrictions in the event that the Corporation does not declare and either pay or set aside a sum sufficient for 
payment of dividends on the Series A preferred stock for the immediately preceding dividend period. The Series A preferred 
stock  is  perpetual  and  has  no  maturity  date,  but  is  redeemable  by  the  Corporation  at  specified  times  subject  to  regulatory 
considerations.

The  Corporation  has  share-based  compensation  plans  under  which  it  awards  shares  of  restricted  stock  units  to 
executive officers, directors and key personnel and stock options to executive officers and key personnel of the Corporation and 
its subsidiaries. Restricted stock units fully vest after a period ranging from three years to five years, and stock options fully 
vest  after  four  years.  A  majority  of  share-based  compensation  awards  include  a  retirement  eligibility  clause  where  qualified 
employees are exempt from the service requirements of the award. This generally results in the recognition of compensation 
expense  at  the  grant  date  for  retirement  eligible  employees.  The  maturity  of  each  option  is  determined  at  the  date  of  grant; 
however, no options may be exercised later than ten years from the date of grant. The options may have restrictions regarding 
exercisability.  The  plans  provide  for  a  grant  of  up  to  7.7  million  common  shares,  plus  shares  under  certain  plans  that  are

forfeited,  expire  or  are  canceled,  which  become  available  for  re-grant.  At  December  31,  2023,  over  3.7  million  shares  were 
available for grant.

The  Corporation  used  a  binomial  model  to  value  stock  options  granted  in  the  periods  presented.  Option  valuation 
models  require  several  inputs,  including  the  expected  stock  price  volatility,  and  changes  in  input  assumptions  can  materially 
affect the fair value estimates. The model used may not necessarily provide a reliable single measure of the fair value of stock 
options.  The  risk-free  interest  rate  assumption  used  in  the  binomial  option-pricing  model  as  outlined  in  the  table  below  was 
based on the federal ten-year treasury interest rate. The expected dividend yield was based on the historical and projected long-
term  dividend  yield  patterns  of  the  Corporation’s  common  shares.  Expected  volatility  assumptions  considered  both  the 
historical volatility of the Corporation’s common stock over a ten-year period and implied volatility based on actively traded 
options on the Corporation’s common stock with pricing terms and trade dates similar to the stock options granted. Expected 
option life was based on historical exercise activity over the contractual term of the option grant (ten years), excluding certain 
forced transactions.

The  estimated  weighted-average  grant-date  fair  value  per  option  and  the  underlying  binomial  option-pricing  model 

assumptions are summarized in the following table:

NOTE 17 - EMPLOYEE BENEFIT PLANS

Defined Benefit Pension and Postretirement Benefit Plans

The  Corporation  has  a  qualified  and  non-qualified  defined  benefit  pension  plan.  In  October  2016,  the  Corporation 
modified  its  defined  benefit  pension  plans  to  freeze  final  average  pay  benefits  as  of  December  31,  2016,  other  than  for 
participants who were age 60 or older as of December 31, 2016, and added a cash balance plan provision effective January 1, 
2017. Active pension plan participants 60 years or older as of December 31, 2016 receive the greater of the final average pay 
formula or the frozen final average pay benefit as of December 31, 2016 plus the cash balance benefit earned after January 1, 
2017. Employees participating in the retirement account plan as of December 31, 2016 were eligible to participate in the cash 
balance  pension  plan  effective  January  1,  2017.  Benefits  earned  under  the  cash  balance  pension  formula,  in  the  form  of  an 
account balance, include contribution credits based on eligible pay earned each month, age and years of service and monthly 
interest credits based on the 30-year Treasury rate.

The  Corporation’s  postretirement  benefit  plan  provides  postretirement  health  care  and  life  insurance  benefits  for 
retirees  as  of  December  31,  1992.  The  plan  also  provides  certain  postretirement  health  care  and  life  insurance  benefits  for  a 
limited  number  of  retirees  who  retired  prior  to  January  1,  2000.  For  all  other  employees  hired  prior  to  January  1,  2000,  a 
nominal benefit is provided. Employees hired on or after January 1, 2000 and prior to January 1, 2007 are eligible to participate 
in the plan on a full contributory basis until Medicare-eligible based on age and service. Employees hired on or after January 1, 
2007 are not eligible to participate in the plan. The Corporation funds the pre-1992 retiree plan benefits with bank-owned life 
insurance.  Effective  January  1,  2022,  the  plan  moved  from  a  self-insured  plan  to  the  Medicare  and  pre-65  individual 
marketplace with a funded Health Reimbursement Arrangement account for those with subsidized coverage. This change did 
not have a material impact on the Corporation's consolidated financial condition, results of operations or cash flow.

insured plan to the Medicare and pre-65 individual marketplace with a funded Health Reimbursement Arrangement account. 

n/a - not applicable

The  expected  long-term  rate  of  return  of  plan  assets  is  the  average  rate  of  return  expected  to  be  realized  on  funds 
invested or expected to be invested over the life of the plan, which has an estimated duration of approximately 9 years as of 
December 31, 2023. The expected long-term rate of return on plan assets is set after considering both long-term returns in the 
general  market  and  long-term  returns  experienced  by  the  assets  in  the  plan.  The  returns  on  the  various  asset  categories  are 
blended to derive an equity and a fixed income long-term rate of return. The Corporation reviews its pension plan assumptions 
on  an  annual  basis  with  its  actuarial  consultants  to  determine  if  assumptions  are  reasonable  and  adjusts  the  assumptions  to 
reflect changes in future expectations.

Plan Assets

The Corporation’s overall investment goals for the qualified defined benefit pension plan are to maintain a portfolio of 
assets of appropriate liquidity and diversification; to generate investment returns (net of all operating costs) that are reasonably 
anticipated to maintain the plan’s fully funded status or to reduce a funding deficit, after taking into account various factors, 
including reasonably anticipated future contributions, expense and the interest rate sensitivity of the plan’s assets relative to that 
of  the  plan’s  liabilities;  and  to  generate  investment  returns  (net  of  all  operating  costs)  that  meet  or  exceed  a  customized 
benchmark  as  defined  in  the  plan's  investment  policy.  Derivative  instruments  are  permissible  for  hedging  and  transactional 
efficiency, but only to the extent that the derivative use enhances the efficient execution of the plan’s investment policy. The 
plan does not directly invest in securities issued by the Corporation and its subsidiaries. The Corporation’s target allocations for 
plan  investments  are  35  percent  to  45  percent  for  equity  securities  and  55  percent  to  65  percent  for  fixed  income,  including 
cash. Equity securities include collective investment and mutual funds and common stock. Fixed income securities include U.S. 
Treasury  and  other  U.S.  government  agency  securities,  mortgage-backed  securities,  corporate  bonds  and  notes,  municipal 
bonds, collateralized mortgage obligations and money market funds.

Fair Value Measurements

The  Corporation’s  qualified  defined  benefit  pension  plan  utilizes  fair  value  measurements  to  record  fair  value 
adjustments and to determine fair value disclosures. The Corporation’s qualified benefit pension plan categorizes investments 
recorded at fair value into a three-level hierarchy, based on the markets in which the investment are traded and the reliability of 
the assumptions used to determine fair value. Refer to Note 1 for a description of the three-level hierarchy.

Following  is  a  description  of  the  valuation  methodologies  and  key  inputs  used  to  measure  the  fair  value  of  the 
Corporation’s qualified defined benefit pension plan investments, including an indication of the level of the fair value hierarchy 
in which the investments are classified.
Mutual funds 

Fair value measurement is based upon the net asset value (NAV) provided by the administrator of the fund. Mutual 
fund NAVs are quoted in an active market exchange, such as the New York Stock Exchange, and are included in Level 1 of the 
fair value hierarchy.

Common stock

Fair value measurement is based upon the closing price quoted in an active market exchange, such as the New York 

Stock Exchange. Level 1 common stock includes domestic and foreign stock and real estate investment trusts.

U.S. Treasury and other U.S. government agency securities

Level  1  securities  include  U.S.  Treasury  securities  that  are  traded  by  dealers  or  brokers  in  active  over-the-counter 
markets.  Fair  value  measurement  is  based  upon  quoted  prices  in  an  active  market  exchange,  such  as  the  New  York  Stock 
Exchange.  Level  2  securities  include  debt  securities  issued  by  U.S.  government  agencies  and  U.S.  government-sponsored 
entities.  The  fair  value  of  Level  2  securities  is  determined  using  quoted  prices  of  securities  with  similar  characteristics,  or 
pricing models based on observable market data inputs, primarily interest rates and spreads.

Corporate and municipal bonds and notes

Fair value measurement is based upon quoted prices of securities with similar characteristics or pricing models based 
on  observable  market  data  inputs,  primarily  interest  rates,  spreads  and  prepayment  information.  Level  2  securities  include 
corporate bonds, municipal bonds, foreign bonds and foreign notes.

Mortgage-backed securities

Fair value measurement is based upon independent pricing models or other model-based valuation techniques such as 
the present value of future cash flows, adjusted for the security's credit rating, prepayment assumptions and other factors, such 
as credit loss and liquidity assumptions, and are included in Level 2 of the fair value hierarchy.

Private placements

Fair  value  is  measured  using  the  NAV  provided  by  fund  management  as  quoted  prices  in  active  markets  are  not 
available. Management considers additional discounts to the provided NAV for market and credit risk. Private placements are 
included in Level 3 of the fair value hierarchy.

F-89

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

 Collective investment funds

Fair value measurement is based upon the NAV provided by the administrator of the fund as a practical expedient to 
estimate  fair  value.  There  are  no  unfunded  commitments  or  redemption  restrictions  on  the  collective  investment  funds.  The 
investments are redeemable daily.

 Fair Values

The  fair  values  of  the  Corporation’s  qualified  defined  benefit  pension  plan  investments  measured  at  fair  value  on  a 
recurring basis at December 31, 2023 and 2022, by asset category and level within the fair value hierarchy, are detailed in the

postretirement benefit plan is fully invested in bank-owned life insurance policies. The fair value of bank-owned life insurance 
policies is based on the cash surrender values of the policies as reported by the insurance companies and is classified in Level 2 
of the fair value hierarchy.

Defined Contribution Plans

Substantially  all  of  the  Corporation’s  employees  are  eligible  to  participate  in  the  Corporation’s  principal  defined 
contribution plan (a 401(k) plan). Under this plan, the Corporation makes core matching cash contributions of 100 percent of 
the first 4 percent of qualified earnings contributed by employees (up to the current IRS compensation limit), invested based on 
employee  investment  elections.  Employee  benefits  expense  included  expense  for  the  plan  of  $27  million  for  the  year  ended 
December 31, 2023 and $24 million for both years ended December 31, 2022 and 2021.

Deferred Compensation Plans

The  Corporation  offers  optional  deferred  compensation  plans  under  which  certain  employees  and  non-employee 
directors (participants) may make an irrevocable election to defer incentive compensation and/or a portion of base salary until 
retirement  or  separation  from  the  Corporation.  The  participant  may  direct  deferred  compensation  into  one  or  more  deemed 
investment  options.  Although  not  required  to  do  so,  the  Corporation  invests  actual  funds  into  the  deemed  investments  as 
directed  by  participants,  resulting  in  a  deferred  compensation  asset,  recorded  in  other  short-term  investments  on  the 
Consolidated  Balance  Sheets  that  offsets  the  liability  to  participants  under  the  plan,  recorded  in  accrued  expenses  and  other 
liabilities.  The  earnings  from  the  deferred  compensation  asset  are  recorded  in  interest  on  short-term  investments  and  other 
noninterest  income  and  the  related  change  in  the  liability  to  participants  under  the  plan  is  recorded  in  salaries  and  benefits 
expense on the Consolidated Statements of Income.

NOTE 18 - INCOME TAXES AND TAX-RELATED ITEMS

The provision for income taxes is calculated as the sum of income taxes due for the current year and deferred taxes. 
Income taxes due for the current year are computed by applying federal and state tax statutes to current year taxable income. 
Deferred  taxes  arise  from  temporary  differences  between  the  income  tax  basis  and  financial  accounting  basis  of  assets  and 
liabilities. Tax-related interest and penalties and foreign taxes are then added to the tax provision.

The current and deferred components of the provision for income taxes were as follows:

The  liability  for  tax-related  interest  and  penalties,  included  in  accrued  expenses  and  other  liabilities  on  the 
Consolidated  Balance  Sheets,  was  less  than  $1  million  and  $5  million  at  December  31,  2023  and  2022,  respectively.  The 
decrease in tax-related interest and penalties was primarily due to a state settlement received in 2023.

In the ordinary course of business, the Corporation enters into certain transactions that have tax consequences. From 
time to time, the Internal Revenue Service (IRS) may review and/or challenge specific interpretive tax positions taken by the 
Corporation with respect to those transactions. The Corporation believes that its tax returns were filed based upon applicable 
statutes, regulations and case law in effect at the time of the transactions. The IRS or other tax jurisdictions, an administrative 
authority or a court, if presented with the transactions, could disagree with the Corporation’s interpretation of the tax law.

After consideration of the effect of the federal tax benefit available on unrecognized state tax benefits, the total amount 
of  unrecognized  tax  benefits  which,  if  recognized,  would  affect  the  Corporation’s  effective  tax  rate  was  approximately  $5 
million and $13 million at December 31, 2023 and 2022, respectively.

Based  on  current  knowledge  and  probability  assessment  of  various  potential  outcomes,  the  Corporation  believes 
current tax reserves are adequate, and the amount of any potential incremental liability arising is not expected to have a material 
adverse  effect  on  the  Corporation’s  consolidated  financial  condition  or  results  of  operations.  Probabilities  and  outcomes  are 
reviewed as events unfold, and adjustments to the reserves are made when necessary.

Deferred  tax  assets  included  $5  million  and  $4  million  of  federal  foreign  tax  credit  carryforwards  at  December  31, 
2023  and  2022,  respectively,  expiring  between  2028  and  2032.  In  addition,  there  were  $2  million  of  state  net  operating  loss 
(NOL) carryforwards at both December 31, 2023 and 2022, expiring between 2024 and 2042. The Corporation believes it is 
more likely than not that the benefit from federal foreign tax credits and certain state NOL carryforwards will not be realized 
and,  accordingly,  maintains  a  federal  valuation  allowance  of  $5  million  and  a  state  valuation  allowance  of  $1  million  at 
December  31,  2023,  compared  to  a  federal  valuation  of  $4  million  and  a  state  valuation  allowance  of  $1  million  in  the 
comparable period in 2022. For further information on the Corporation’s valuation policy for deferred tax assets, refer to Note

NOTE 19 - TRANSACTIONS WITH RELATED PARTIES 

The  Corporation’s  banking  subsidiaries  had,  and  expect  to  have  in  the  future,  transactions  with  the  Corporation’s 
directors  and  executive  officers,  companies  with  which  these  individuals  are  associated  and  certain  related  individuals.  Such 
transactions were made in the ordinary course of business and included extensions of credit, leases and professional services. 
With respect to extensions of credit, all were made on substantially the same terms, including interest rates and collateral, as 
those  prevailing  at  the  same  time  for  comparable  transactions  with  other  customers  and  did  not,  in  management’s  opinion, 
involve more than normal risk of collectibility or present other unfavorable features. The aggregate amount of loans attributable 
to persons who were related parties at December 31, 2023 totaled $57 million at the beginning of 2023 and $81 million at the 
end of 2023. During 2023, new loans to related parties aggregated $277 million and repayments totaled $253 million.

NOTE 20 - REGULATORY CAPITAL 

Banking regulations limit the transfer of assets in the form of dividends, loans or advances from the bank subsidiaries 
to the parent company. Under the most restrictive of these regulations, the aggregate amount of dividends which can be paid to 
the parent company, without prior approval from bank regulatory agencies, approximated $400 million at January 1, 2024, plus 
2024 net profits. Substantially all the assets of the Corporation’s banking subsidiaries are restricted from transfer to the parent 
company of the Corporation in the form of loans or advances.

The Corporation’s subsidiary banks declared dividends of $675 million, $1.0 billion and $852 million in 2023, 2022 

and 2021, respectively.

The Corporation and its U.S. banking subsidiaries are subject to various regulatory capital requirements administered 
by  federal  and  state  banking  agencies  under  the  Basel  III  regulatory  framework  (Basel  III).  This  regulatory  framework 
establishes comprehensive methodologies for calculating regulatory capital and risk-weighted assets (RWA). Basel III also set 
minimum capital ratios as well as overall capital adequacy standards.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

Under Basel III, regulatory capital comprises Common Equity Tier 1 (CET1) capital, additional Tier 1 capital and Tier 
2 capital. CET1 capital predominantly includes common shareholders' equity, less certain deductions for goodwill, intangible 
assets and deferred tax assets that arise from net operating losses and tax credit carry-forwards. Additionally, the Corporation 
has  elected  to  permanently  exclude  capital  in  accumulated  other  comprehensive  income  (AOCI)  related  to  debt  securities 
classified as available-for-sale as well as for cash flow hedges and defined benefit postretirement plans from CET1, an option 
available  to  standardized  approach  entities  under  Basel  III.  Tier  1  capital  incrementally  includes  noncumulative  perpetual 
preferred stock. Tier 2 capital includes Tier 1 capital as well as subordinated debt qualifying as Tier 2 and qualifying allowance 
for  credit  losses.  In  addition  to  the  minimum  risk-based  capital  requirements,  the  Corporation  and  its  Bank  subsidiaries  are 
required to maintain a minimum capital conservation buffer, in the form of common equity, of 2.5 percent in order to avoid 
restrictions on capital distributions and discretionary bonuses. 

The  Corporation  computes  RWA  using  the  standardized  approach.  Under  the  standardized  approach,  RWA  is 
generally  based  on  supervisory  risk-weightings  which  vary  by  counterparty  type  and  asset  class.  Under  the  Basel  III 
standardized  approach,  capital  is  required  for  credit  risk  RWA,  to  cover  the  risk  of  unexpected  losses  due  to  failure  of  a 
customer  or  counterparty  to  meet  its  financial  obligations  in  accordance  with  contractual  terms;  and  if  trading  assets  and 
liabilities  exceed  certain  thresholds,  capital  is  also  required  for  market  risk  RWA,  to  cover  the  risk  of  losses  due  to  adverse 
market movements or from position-specific factors.

Quantitative  measures  established  by  regulation  to  ensure  capital  adequacy  require  the  maintenance  of  minimum 
amounts  and  ratios  of  CET1,  Tier  1  and  total  capital  (as  defined  in  the  regulations)  to  average  and/or  risk-weighted  assets. 
Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by 
regulators that, if undertaken, could have a direct material effect on the Corporation’s financial statements. At December 31, 
2023 and 2022, the Corporation and its U.S. banking subsidiaries exceeded the ratios required for an institution to be considered 
“well  capitalized”.  For  U.S.  banking  subsidiaries,  those  requirements  were  total  risk-based  capital,  Tier  1  risk-based  capital, 
CET1  risk-based  capital  and  leverage  ratios  greater  than  10  percent,  8  percent,  6.5  percent  and  5  percent,  respectively,  at 
December  31,  2023  and  2022.  For  the  Corporation,  requirements  to  be  considered  "well  capitalized"  were  total  risk-based 
capital and Tier 1 risk-based capital ratios greater than 10 percent and 6 percent, respectively, at December 31, 2023 and 2022. 
There have been no conditions or events since December 31, 2023 that management believes have changed the capital adequacy 
classification of the Corporation or its U.S. banking subsidiaries.

The following is a summary of the capital position of the Corporation and Comerica Bank, its principal banking subsidiary.

NOTE 21 - CONTINGENT LIABILITIES

Legal Proceedings and Regulatory Matters

The  Corporation  and  certain  of  its  subsidiaries  are  subject  to  various  other  pending  or  threatened  legal  proceedings 
arising out of the normal course of business or operations. The Corporation believes it has substantial defenses to the claims 
asserted  against  it in its other currently outstanding legal  proceedings and, with respect to such legal  proceedings, intends to 
continue to defend itself vigorously, litigating or settling cases according to management’s judgment as to what is in the best 
interests  of  the  Corporation  and  its  shareholders.  Settlement  may  result  from  the  Corporation's  determination  that  it  may  be 
more prudent financially to settle, rather than litigate, and should not be regarded as an admission of liability. 

Further, from time to time, the Corporation is also subject to examinations, inquiries and investigations by regulatory 
authorities in areas including, but not limited to, compliance, risk management and consumer protection, which could lead to 
administrative  or  legal  proceedings  or  settlements.  For  example,  the  Consumer  Financial  Protection  Bureau  (CFPB)  is 
investigating certain of the Corporation's practices, and the Corporation has responded and continues to respond to the CFPB. 
We  are  unable  to  predict  the  outcome  of  these  discussions  at  this  time.  Remedies  in  these  proceedings  or  settlements  may 
include fines, penalties, restitution or alterations in the Corporation's business practices and may result in increased operating 
expenses or decreased revenues.

On  at  least  a  quarterly  basis,  the  Corporation  assesses  its  potential  liabilities  and  contingencies  in  connection  with 
outstanding legal proceedings and regulatory matters utilizing the latest information available. On a case-by-case basis, accruals 
are established for those legal claims and regulatory matters for which it is probable that a loss will be incurred and the amount 
of such loss can be reasonably estimated. The actual costs of resolving these claims and regulatory matters may be substantially 
higher or lower than the amounts accrued. Based on current knowledge, and after consultation with legal counsel, management 
believes current accruals are adequate, and the amount of any incremental liability arising from these matters is not expected to 
have a material adverse effect on the Corporation’s consolidated financial condition, results of operations or cash flows. Legal 
fees of $26 million, $17 million and $14 million for the years ended December 31, 2023, 2022 and 2021, respectively, were 
included in other noninterest expenses on the Consolidated Statements of Income.

For matters where a loss is not probable, the Corporation has not established an accrual. The Corporation believes the 
estimate of the aggregate range of reasonably possible losses, in excess of established accruals, for all legal proceedings and 
regulatory matters in which it is involved is from zero to approximately $202 million at December 31, 2023. This estimated 
aggregate  range  of  reasonably  possible  losses  is  based  upon  currently  available  information  for  those  legal  proceedings  and 
regulatory matters in which the Corporation is involved, taking into account the Corporation’s best estimate of such losses for 
those legal cases and regulatory matters for which such estimate can be made. For certain legal cases and regulatory matters, the 
Corporation does not believe that an estimate can currently be made. The Corporation’s estimate involves significant judgment, 
given the varying stages of the legal proceedings and regulatory matters (including the fact many are currently in preliminary 
stages), the existence in certain legal proceedings of multiple defendants (including the Corporation) whose share of liability 
has  yet  to  be  determined,  the  numerous  yet-unresolved  issues  in  many  of  the  legal  proceedings  and  regulatory  matters 
(including issues regarding class certification and the scope of many of the claims) and the attendant uncertainty of the various 
potential outcomes of such legal proceedings and regulatory matters. Accordingly, the Corporation’s estimate will change from 
time to time, and actual losses may be more or less than the current estimate.

In  the  event  of  unexpected  future  developments,  it  is  possible  that  the  ultimate  resolution  of  these  matters,  if 

unfavorable, may be material to the Corporation's consolidated financial condition, results of operations or cash flows.

For information regarding income tax contingencies, refer to Note 18.

NOTE 22 - STRATEGIC LINES OF BUSINESS

The Corporation has strategically aligned its operations into three major business segments: the Commercial Bank, the 
Retail Bank and Wealth Management. These business segments are differentiated based on the type of customer and the related 
products  and  services  provided.  In  addition  to  the  three  major  business  segments,  the  Finance  Division  is  also  reported  as  a 
segment.  Business  segment  results  are  produced  by  the  Corporation’s  internal  management  accounting  system.  This  system 
measures  financial  results  based  on  the  internal  business  unit  structure  of  the  Corporation.  The  performance  of  the  business 
segments  is  not  comparable  with  the  Corporation's  consolidated  results  and  is  not  necessarily  comparable  with  similar 
information  for  any  other  financial  institution.  Additionally,  because  of  the  interrelationships  of  the  various  segments,  the 
information  presented  is  not  indicative  of  how  the  segments  would  perform  if  they  operated  as  independent  entities.  The 
management  accounting  system  assigns  balance  sheet  and  income  statement  items  to  each  business  segment  using  certain 
methodologies,  which  are  regularly  reviewed  and  refined.  From  time  to  time,  the  Corporation  may  make  reclassifications 
among  the  segments  to  more  appropriately  reflect  management's  current  view  of  the  segments,  and  methodologies  may  be 

F-95

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

modified as the management accounting system is enhanced and changes occur in the organizational structure and/or product 
lines. For comparability purposes, amounts in all periods are based on business unit structure and methodologies in effect at 
December 31, 2023.

Net interest income for each segment reflects the interest income generated by earning assets less interest expense on 
interest-bearing  liabilities  plus  the  net  impact  from  associated  internal  funds  transfer  pricing  (FTP)  funding  credits  and 
charges.  The  FTP  methodology  allocates  credits  to  each  business  segment  for  deposits  and  other  funds  provided  as  well  as 
charges for loans and other assets being funded. This credit or charge is based on matching stated or implied maturities for these 
assets and liabilities. The FTP crediting rates on deposits and other funds provided reflect the long-term value of deposits and 
other funding sources based on their implied maturity. Due to the longer-term nature of implied maturities, FTP crediting rates 
are generally less volatile than changes in interest rates observed in the market. FTP charge rates for funding loans and other 
assets  reflect  a  matched  cost  of  funds  based  on  the  pricing  and  duration  characteristics  of  the  assets.  As  a  result  of  applying 
matched funding, interest revenue for each segment resulting from loans and other assets is generally not impacted by changes 
in interest rates. Therefore, net interest income for each segment primarily reflects the volume of loans and other earning assets 
at the spread over the matched cost of funds, as well as the volume of deposits at the associated FTP crediting rates. Generally, 
in periods of rising interest rates, FTP charge rates for funding loans and FTP crediting rates on deposits will increase, with FTP 
crediting rates for deposits typically repricing at a slower pace than FTP charge rates for funding loans. 

For acquired loans and deposits, matched maturity funding is determined based on origination date. Accordingly, the 
FTP  process  reflects  the  transfer  of  interest  rate  risk  exposures  to  the  Corporate  Treasury  department  within  the  Finance 
segment,  where  such  exposures  are  centrally  managed.  The  allowance  for  credit  losses  is  allocated  to  the  business  segments 
based  on  the  methodology  used  to  estimate  the  consolidated  allowance  for  credit  losses  described  in  Note  1.  The  related 
provision for credit losses is assigned based on the amount necessary to maintain an allowance for credit losses appropriate for 
each business segment. Noninterest income and expenses directly attributable to a line of business are assigned to that business 
segment.  Direct  expenses  incurred  by  areas  whose  services  support  the  overall  Corporation  are  allocated  to  the  business 
segments  as  follows:  product  processing  expenditures  are  allocated  based  on  standard  unit  costs  applied  to  actual  volume 
measurements; administrative expenses are allocated based on estimated time expended; and corporate overhead is assigned 50 
percent based on the ratio of the business segment’s noninterest expenses to total noninterest expenses incurred by all business 
segments and 50 percent based on the ratio of the business segment’s attributed equity to total attributed equity of all business 
segments. Equity is attributed based on credit, operational and interest rate risks. Most of the equity attributed relates to credit 
risk,  which  is  determined  based  on  the  credit  score  and  expected  remaining  life  of  each  loan,  letter  of  credit  and  unused 
commitment  recorded  in  the  business  segments.  Operational  risk  is  allocated  based  on  loans  and  letters  of  credit,  deposit 
balances,  non-earning  assets,  trust  assets  under  management,  certain  noninterest  income  items,  and  the  nature  and  extent  of 
expenses  incurred  by  business  units.  Virtually  all  interest  rate  risk  is  assigned  to  Finance,  as  are  the  Corporation’s  hedging 
activities.

The  following  discussion  provides  information  about  the  activities  of  each  business  segment.  A  discussion  of  the 
financial  results  and  the  factors  impacting  2023  performance  can  be  found  in  "Strategic  Lines  of  Business"  section  of  the 
financial review.

REPORT OF MANAGEMENT

The  management  of  Comerica  Incorporated  (the  Corporation)  is  responsible  for  the  accompanying  consolidated 
financial statements and all other financial information in this Annual Report. The consolidated financial statements have been 
prepared in conformity with U.S. generally accepted accounting principles and include amounts which of necessity are based on 
management’s best estimates and judgments and give due consideration to materiality. The other financial information herein is 
consistent with that in the consolidated financial statements.

In  meeting  its  responsibility  for  the  reliability  of  the  consolidated  financial  statements,  management  develops  and 
maintains effective internal controls, including those over financial reporting, as defined in the Securities and Exchange Act of 
1934, as amended. The Corporation’s internal control over financial reporting includes 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 Corporation; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of 
the  consolidated  financial  statements  in  conformity  with  U.S.  generally  accepted  accounting  principles,  and  that  receipts  and 
expenditures  of  the  Corporation  are  made  only  in  accordance  with  authorizations  of  management  and  directors  of  the 
Corporation; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or 
disposition of the Corporation’s assets that could have a material effect on the consolidated financial statements.

Management  assessed,  with  participation  of  the  Corporation’s  Chief  Executive  Officer  and  Chief  Financial  Officer, 
internal  control  over  financial  reporting  as  it  relates  to  the  Corporation’s  consolidated  financial  statements  presented  in 
conformity with U.S. generally accepted accounting principles as of December 31, 2023. The assessment was based on criteria 
for  effective  internal  control  over  financial  reporting  described  in  Internal  Control—Integrated  Framework  issued  by  the 
Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). Based on this 
assessment, management determined that internal control over financial reporting is effective as it relates to the Corporation’s 
consolidated  financial  statements  presented  in  conformity  with  U.S.  generally  accepted  accounting  principles  as  of 
December 31, 2023.

Because  of  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 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  Corporation's  internal  control  over  financial  reporting  as  of  December  31,  2023  has  been  audited  by  Ernst  & 

Young LLP, an independent registered public accounting firm, as stated in their accompanying report. 

The  Corporation’s  Board  of  Directors  oversees  management’s  internal  control  over  financial  reporting  and  financial 
reporting  responsibilities  through  its  Audit  Committee  as  well  as  various  other  committees.  The  Audit  Committee,  which 
consists of directors who are not officers or employees of the Corporation, meets regularly with management, internal audit and 
the  independent  public  accountants  to  assure  that  the  Audit  Committee,  management,  internal  auditors  and  the  independent 
public accountants are carrying out their responsibilities, and to review auditing, internal control and financial reporting matters.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of Comerica Incorporated

Opinion on Internal Control over Financial Reporting

We have audited Comerica Incorporated and subsidiaries’ internal control over financial reporting as of December 31, 2023, 
based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of 
the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Comerica Incorporated and subsidiaries (the 
Corporation) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, 
based on the COSO criteria. 

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 Corporation as of December 31, 2023 and 2022, and the related consolidated 
statements of income, comprehensive income, changes in shareholders' equity and cash flows for each of the three years in the 
period ended December 31, 2023, and the related notes of the Corporation and our report dated February 28, 2024 expressed an 
unqualified opinion thereon.

Basis for Opinion

The  Corporation’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  Report  of 
Management. Our responsibility is to express an opinion on the Corporation’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 
Corporation 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  included  obtaining  an  understanding  of  internal  control  over  financial  reporting,  assessing  the  risk  that  a  material 
weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and 
performing  such  other  procedures  as  we  considered  necessary  in  the  circumstances.  We  believe  that  our  audit  provides  a 
reasonable basis for our opinion.

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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of Comerica Incorporated

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Comerica Incorporated and subsidiaries (the Corporation) as 
of  December  31,  2023  and  2022,  and  the  related  consolidated  statements  of  income,  comprehensive  income,  changes  in 
shareholders' equity and cash flows for each of the three years in the period ended December 31, 2023, and the related notes 
(collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present 
fairly, in all material respects, the financial position of the Corporation at December 31, 2023 and 2022, and the consolidated 
results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, 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 Corporation’s internal control over financial reporting as of December 31, 2023, based on criteria established in 
Internal  Control-Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission 
(2013 framework) and our report dated February 28, 2024, expressed an unqualified opinion thereon. 

Basis for Opinion 

These financial statements are the responsibility of the Corporation’s management. Our responsibility is to express an opinion 
on the Corporation’s 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  Corporation  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 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  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 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 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 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  financial  statements  and  (2)  involved  our  especially  challenging,  subjective  or  complex  judgments.  The 
communication of the 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.

Description of 
the Matter

Allowance for credit losses
The Corporation’s loan portfolio and the associated allowance for credit losses (ACL) were $52.1 billion 
and  $728  million  as  of  December  31,  2023,  respectively.  The  allowance  for  credit  losses  represents 
management’s  estimate  of  expected  credit  losses  over  the  contractual  life  of  the  loan  portfolio  at  the 
balance sheet date. The allowance for credit losses includes credit loss estimates for loans evaluated on an 
individual basis, such as for certain nonaccrual loans and collective loss estimates for pools of loans with 
similar risk characteristics. The Corporation determines the allowance for pools of loans with similar risk 
characteristics  by  applying  loss  factors  to  amortized  cost  balances  over  the  remaining  contractual  life. 
Loss factors are based on estimated probability of default, set to a default horizon based on contractual 
life,  and  loss  given  default.  Through  the  use  of  various  models,  historical  estimates  are  calibrated  to 
economic forecasts over the reasonable and supportable forecast period based on economic variables that 
statistically  correlate  with  each  of  the  probability  of  default  and  loss  given  default  pools.  Qualitative 
adjustments are then made to bring the allowance to the level management believes is appropriate based 
on factors that have not otherwise been fully accounted for in the quantitative analysis. Examples of these 
adjustments include 1) foresight risk, 2) input imprecision, and 3) model imprecision.

Auditing management’s estimate of the allowance for credit losses involved a high degree of subjectivity 
due to the highly judgmental nature of the expected loss models and the qualitative adjustments included 
in the ACL. Management applies significant judgment when selecting the expected loss models to be used 
to  determine  the  allowance  and  the  inputs  used  in  those  models  as  well  as  in  applying  qualitative 
adjustments. These determinations could have a significant effect on the ACL.

How We 
Addressed the 
Matter in Our 
Audit

We obtained an understanding of the Corporation’s process for establishing the ACL, including selection 
of the models, inputs used in the models, monitoring of the models, and the qualitative adjustments made 
to  the  ACL.  We  evaluated  the  design  and  tested  the  operating  effectiveness  of  the  controls  over  1) 
determining the appropriateness of the models used to estimate quantitative components of the ACL, 2) 
validating the models used to estimate quantitative components of the ACL, 3) selecting the appropriate 
inputs and assumptions within the models, 4) monitoring of the models including the assessment of the 
output,  5)  determining  the  appropriateness  of  the  qualitative  reserve  methodology,  including  the 
identification and the assessment for the need for qualitative adjustments, 6) validating the relevance and 
reliability  of  data  used  to  estimate  the  various  components  of  the  qualitative  reserves,  and  7) 
management’s review and approval of qualitative adjustments and model output.

To test the appropriateness of the models used by management to estimate quantitative components of the 
ACL, with the support of specialists, we evaluated the model methodology and model performance, and 
tested  key  modeling  assumptions  used  within  the  models.  To  test  the  qualitative  adjustments,  we 
evaluated  the  identification  and  measurement  of  the  qualitative  adjustments,  including  the  basis  for 
concluding  an  adjustment  was  warranted  when  considering  the  potential  impact  of  foresight  risk,  input 
imprecision and model imprecision, evaluated the appropriateness of the data used by the Corporation to 
estimate  the  qualitative  adjustments,  recalculated  the  analyses  used  by  management  to  determine  the 
qualitative  adjustments,  and  analyzed  the  changes  in  assumptions  and  components  of  the  qualitative 
reserves relative to changes in the Corporation’s loan portfolio. For example, we evaluated the data and 
information  utilized  by  management  to  estimate  the  qualitative  adjustments  by  independently  obtaining 
and comparing to historical loan data, third-party macroeconomic data, and peer bank data to assess the 
appropriateness of the information and to consider whether new or contradictory information existed. We 
also  evaluated  if  qualitative  adjustments  were  based  on  a  comprehensive  framework,  well-documented, 
and consistently applied.
