2014 COMERICA INCORPORATED ANNUAL REPORTKeeping the Promise®Comerica Incorporated (NYSE: CMA) is a financial services company headquartered in Dallas, Texas, and strategically aligned by three business segments: The Business Bank, The Retail Bank, and Wealth Management. Comerica focuses on relationships, and helping people and businesses be successful. In addition to Texas, Comerica Bank locations can be found in Arizona, California, Florida and Michigan, with select businesses operating in several other states, as well as in Canada and Mexico.

The national economy began the year with many challenges, but finished with strong job 

growth,  and  increasing  business  and  consumer  confidence.  Throughout  2014,  we  remained 

focused  on  keeping  our  promise  of  providing  a  higher  level  of  banking  to  our  customers  by 

serving as their trusted advisor and delivering an exceptional customer experience that exceeds 

expectations. In 2014, we also continued to make a positive difference in the communities where 

we live and work. All the while, we remained diligent in managing the things we can control, such 

as our expenses.

Founded 165 years ago, the Comerica of today has the resources of a large bank and the 

customer-centric culture of a community bank. We have a strong presence in Texas, California and 

Michigan, as well as operations in Arizona and Florida. Our strategy is to have balance between 

our markets, which should help us achieve consistent and sustainable growth over time. We have 

made meaningful progress in that regard over the past 10 years.

We provide comprehensive banking services through our Business Bank, Retail Bank, and 

Wealth Management segments. Our focus on relationships in all three segments makes a positive 

difference for us in this highly competitive, low-rate environment.

2014 Financial Results

Our 2014 net income increased 10 percent from a year ago, reflecting lower litigation-related 

expenses, a decrease in pension expense, and our continued drive for efficiency. We reported 

2014 net income of $593 million, or $3.16 per diluted share, compared to $541 million, or $2.85 

per diluted share for 2013. Excluding the impact to 2013 results of an unfavorable jury verdict in 

a lender liability case, which decreased 2013 net income by $28 million, or 15 cents per share, 

2014 net income increased $24 million, or 4 percent, and earnings per diluted share increased 

16 cents, or 5 percent.

Our loan and deposit growth was solid in 2014. Average total loans increased $2.2 billion, or 

5 percent, to $46.6 billion in 2014, primarily reflecting increases of $1.7 billion, or 6 percent, in 

commercial loans, $158 million, or 10 percent, in residential mortgage loans and $117 million, or 

5 percent, in consumer loans. The increase in commercial loans was primarily driven by increases 

in Technology and Life Sciences, National Dealer Services, Energy and general Middle Market, 

partially offset by a decrease in Mortgage Banker Finance.

Average total deposits increased $3.1 billion, or 6 percent, to a record $54.8 billion in 2014, 

reflecting  increases  of  $2.6  billion,  or  12  percent,  in  noninterest-bearing  deposits  and  $433 

million, or 1 percent, in interest-bearing deposits. We increased deposits in nearly all business 

lines and all three of our major markets, reflecting our focus on relationship banking.

BABB JR.Chairman and Chief Executive OfficerWe had modestly lower net interest income in 2014 of $1.7 billion, a decrease of $17 million, 

or 1 percent, primarily as a result of a $15 million decrease in accretion of the purchase discount 

on our acquired loan portfolio. The benefit from an increase in loan volume was offset by continued 

pressure on yields from the low-rate environment and loan portfolio dynamics.

Credit  quality  continued  to  be  strong  in  2014.  As  a  result,  the  provision  for  credit  losses 

decreased  $19  million  to  $27  million  in  2014,  compared  to  2013.  Net  charge-offs  were  $25 

million, or 0.05 percent of average loans for 2014, compared to $73 million or 0.16 percent of 

average loans for 2013.

Noninterest  income  decreased  $14  million,  or  2  percent,  to  $868  million  in  2014.  The 

decrease was primarily the result of a $19 million decrease in noncustomer-driven fee income 

categories, partially offset by a $5 million increase in customer-driven fees.

We continued to carefully manage expenses in 2014. Noninterest expenses decreased $96 

million,  or  6  percent,  to  $1.6  billion,  compared  to  2013,  primarily  reflecting  decreases  of  $48 

million in litigation-related expenses and $47 million in pension expense.

Comerica continued to maintain a very strong capital position. Our regulatory capital levels 

remain comfortably above the threshold to be considered well capitalized.

On January 21, 2014, and April 22, 2014, the board of directors increased the quarterly 

cash dividend for common stock by 12 percent and 5 percent, respectively. We repurchased 5.2 

million shares in 2014 under our share repurchase program. The dividend increases and share 

buyback reflect our strong capital position and solid financial performance. Through the buyback 

and dividends, we returned $392 million, or 66 percent, of 2014 net income to shareholders.

In March 2014, the Federal Reserve did not object to our 2014 Capital Plan submission and 

the capital actions contemplated for the period spanning the second quarter of 2014 through the 

first quarter of 2015. We again participated in the Capital Plan process for 2015.

Our tangible book value per share increased 6 percent over the past year, to $37.72, as we 

continue to focus on creating long-term shareholder value.*

* See Supplemental Financial Data section for reconcilements of non-GAAP financial measures.

Increased Regulatory and Technology Demands

Along with the rest of the financial services industry, Comerica faces increased regulatory 

and technology demands. We incurred more than $25 million in expense in 2014 to comply with 

regulations. We will continue to add staff and invest in technology for regulatory-related projects 

such as capital planning, stress testing, enterprise risk, and the Liquidity Coverage Ratio, or LCR.

Irrespective of our technology spend for compliance-related projects, technology is becoming 

an increasingly important element in the execution of our strategy. Customers are growing much 

more comfortable with online means of accessing their accounts and conducting routine banking 

transactions.

security threats across the industry that are driving increased investments in information security. 

Such investments enable our customers to better protect themselves and the bank to better detect 

sophisticated attempts to penetrate our defenses.

At the same time, we see our investments in technology as helping to improve data quality, 

deepen insights into customer demands, and provide for greater overall efficiency.

With respect to LCR, the final rule was issued in September 2014. The LCR was included as 

part of the Basel Accords to help ensure that banks can withstand short-term liquidity disruptions. 

Banks of our size will need to phase in compliance beginning in 2016 and be subject to a monthly 

calculation. We continue to feel comfortable that we will meet the proposed phase-in threshold 

within the required time frame, which for us is 90 percent by January 2016 and 100 percent by 

January 2017.

Diverse Footprint, Key Business Segments Drive Growth

Our diverse footprint covers seven of the largest 10 cities in the country, as well as many just 

outside the top 10. We find customers are attracted to Comerica because we get to know and 

understand  them.  Our  relationship  banking  model  does  make  a  positive  difference  for  us  and 

remains a competitive advantage.

Texas  and  California  are  the  two  largest  economies  in  the  United  States.  We  have  had  a 

presence in these high-growth markets for more than a quarter century.

Within  Texas,  we  continue  to  leverage  our  standing  as  the  largest  U.S.  commercial  bank 

headquartered  in  the  state,  a  source  of  pride  for  us  and  our  customers.  We  strengthened  our 

Middle Market Banking team across Texas in 2014 with the addition of bankers in Houston, Dallas 

and, most recently, Austin.

Texas is home to our Energy business, which is focused on well-established middle market 

companies. We have extensive knowledge of the energy industry, with a long history of managing 

a solid portfolio that has performed exceptionally well through a number of cycles. Our Energy 

business strategy is built to withstand the kind of energy sector volatility that we saw late in 2014.

Average loans and deposits in Texas in 2014 were up 10 percent and 5 percent, respectively, 

compared to a year ago.

California  is  home  to  our  Technology  and  Life  Sciences  business,  Entertainment  group, 

and Financial Services Division, which is our title and escrow business. Our expertise in these 

businesses and others help differentiate us from the competition in California. California also is 

the largest market for our National Dealer Services business – another industry in which we have 

accumulated years of experience.

Average loans and deposits in California in 2014 were both up 10 percent compared to a 

year ago.

have maintained our No. 2 deposit market share in the state, based on the latest FDIC data. We 

continue to benefit from our reputation as a steady, reliable main street bank, committed to the 

region. We were proud to support the City of Detroit through our $1 million commitment to the 

“grand bargain,” which helped the city successfully emerge from bankruptcy, while supporting 

city pensioners and protecting the great works at the Detroit Institute of Arts.

Average loans in Michigan were relatively stable in 2014 compared to a year ago, and average 

deposits increased 3 percent.

Together with our diverse footprint, growth is driven by our three strategic lines of business.

Business Bank

Within  the  Business  Bank,  our  clear  strengths  are  our  relationship  model  and  approach 

to commercial banking. We are not just “lenders,” as we strive to be strategic partners with our 

customers.  Through  our  relationship  banker  model,  we  have  a  singular  point  of  contact  who 

not only understands our customers’ strategic initiatives, but is a conduit to key specialists who 

customize solutions that will support our customers in attaining their goals.

Our tenured and experienced Business Bank colleagues provide for a consistent delivery of 

the promise we make to raise the expectations of what a bank can be. With a strong foundation 

provided by our active credit training and mentoring programs, and the long tenure of our Business 

Bank managers, who average almost 20 years of experience, we are proudly delivering value to 

our customers.

Nationally,  we  provide  a  broad  spectrum  of  specialized  business  lines,  such  as  National 

Dealer  Services,  Mortgage  Banker  Finance,  and  Technology  and  Life  Sciences.  We  opened  a 

new Technology and Life Sciences office in New York in 2014. With that addition, we now have a 

physical presence in nine of the top 10 markets for new venture capital investments in the United 

States.

In 2014, the Business Bank focused on achieving profitable growth through the addition of 

new and expanded customer relationships, and selectively reallocating resources to those markets 

and business lines that provide the greatest opportunities for us. All the while, the Business Bank 

maintained pricing discipline in an increasingly competitive environment by focusing on our value 

proposition and by acting as a strategic partner with our customers.

In addition, the Business Bank rolled out several key initiatives in 2014 that are aligned with 

our long-term corporate strategy. Among these initiatives are “High Performance Planning and 

Execution” and “Trusted Advisor.”

Piloted in our Middle Market groups with almost immediate success, our High Performance 

Planning and Execution initiative provides analytical data that leads to specific action plans geared 

at improving the overall financial performance of our portfolio.

Comerica Brand PromiseWithinthe Business Bank, ourclear strengths are our relationship model and approach to commercial banking.Trusted  Advisor  is  a  Comerica  developed  and  led  program  that  provides  our  relationship 

bankers  and  other  customer-facing  colleagues  in  the  Business  Bank  with  the  tools  they  need 

to  build  mutually  beneficial  relationships  through  quality  customer  experiences  and  tailored 

financial solutions. The program focuses our business bankers on identifying solutions that help 

our customers to manage their growth, cash, risk and wealth.

Technology and integration played important roles within the Treasury Management Services 

area of the Business Bank in 2014. We introduced a suite of new integrated solutions to help 

our customers be more successful in managing their payables, receivables and cash flow. These 

new solutions – Integrated Payables Web, Integrated Receivables and Integrated Cash Position 

Manager  –  certainly  leverage  the  latest  technology,  but  the  true  value  these  solutions  provide 

can only be achieved if they are designed with the customer in mind. That’s why we formed the 

Treasury Management Strategic Advisory Council in 2014. The Council’s membership includes 

Treasury Management customers in all markets who give us their feedback, ideas and insights to 

improve the services we provide. In its first year of operation, the Council has proven to be one of 

the most critical inputs to our product road map and our design of commercial mobile solutions.

Commercial  cards  continue  to  gain  traction  and  are  a  key  component  of  our  Treasury 

Management Services integrated payables offering as customers seek efficient, paperless solutions 

to meet their cash management needs. Comerica was ranked as the 10th largest U.S. Visa and 

MasterCard commercial card issuer in 2013, according to the August 2014 edition of The Nilson 

Report. In particular, Comerica was ranked as the largest issuer of prepaid commercial cards and 

fifth largest issuer of fleet cards.

Comerica is proud to serve as the U.S. Department of the Treasury’s exclusive financial agent 

for the Direct Express® Debit MasterCard®, a prepaid debit card and electronic payment option 

for  federal  benefits,  which  provides  a  convenient  alternative  to  paper  checks.  Since  the  U.S. 

Department of the Treasury began surveying cardholders in 2009, the Direct Express® program 

has  maintained  very  high  customer  satisfaction  ratings  of  94  percent  or  above.  This  program 

provides monthly benefits payments via safe, reliable channels for individuals who typically do 

not  have  traditional  bank  accounts.  In  September  2014,  the  U.S.  Department  of  the  Treasury 

announced  it  has  retained  Comerica  as  the  exclusive  financial  agent  for  the  Direct  Express® 

program for another five years, through 2020.

In 2014, we also announced our agreement with Vantiv, Inc., to provide payment processing 

solutions for our Merchant Services customers. Comerica’s Merchant Services enable businesses 

to enjoy the convenience of accepting card payments utilizing the latest in technology, including 

advanced  security  products  and  reporting  tools.  While  at  year-end  2014  we  were  just  getting 

started with Vantiv, our pipeline, closed sales and activations were all exceeding expectations.

upon  its  successful  2014  initiatives  and  supporting  our  continued  growth  and  success  in  an 

increasingly regulated, competitive, and dynamic environment.

Retail Bank and Wealth Management

The Retail Bank and Wealth Management segments are key parts of our strategy of growth 

and balance. Through strong collaboration with colleagues in other business units, we bring a broad 

spectrum of products and services to customers and prospects in each of our primary markets.

Our  Retail  Bank  and  Wealth  Management  segments  provide  us  a  stable,  low-cost  source 

of funding through core deposit generation, which has gained even more importance since the 

announcement of the Basel III LCR requirements.

Like the bank as a whole, the Retail Bank and Wealth Management segments are focused 

on operating efficiencies that go beyond cutting expenses. This includes streamlining procedures, 

rethinking the way we have done business in the past, and investing in technology to provide even 

more convenience to our customers. For example, we invested in technology that enabled us to 

offer  a  number  of  enhancements  to  our  consumer  mobile  banking  service  in  2014,  including 

alerts, Click&Capture Deposit, person-to-person transfers, and a new, enhanced iPad application.

Technology is also at the forefront in the evolution now underway in branch banking. It really 

is no longer a one-size-fits-all strategy. The evolution is driven, in part, by the speed at which new 

technologies and capabilities are being embraced by the consumer.

That is why we are excited about piloting our experienceCenter. Designed to be experimental, 

the experienceCenter is a true test-and-learn environment that allows us to vet new technologies, 

delivery  channels  and  services  in  real  time.  It  also  offers  us  a  way  to  identify  and  measure 

technologies best suited to serve our clients and colleagues. This helps ensure wise spending as 

only the most successful concepts go into production. The first such pilot opened in 2014 at a 

banking center in Auburn Hills, Michigan.

Our banking network remains strategically aligned within the key urban areas of our primary 

markets. We believe our network is well situated. We regularly review it to ensure we have optimal 

coverage to meet customer needs. We plan to add banking centers as the right opportunities arise 

and as the economy continues to improve.

Small Business is an important part of our Retail Bank, just as small businesses are important 

to the growth of our national economy.

We were pleased to introduce our Small Business Resource Center in 2014. The Center is 

a web-based informational space that brings a wealth of tools and resources for business owners 

and leaders right to their fingertips. The materials and interactive components are practical, easy 

to use and assist our customers in taking the right steps to grow and manage their businesses.

Michigan,  to  go  along  with  the  group’s  presence  in  Texas  and  Arizona.  The  group  applies  our 

specialty lending expertise to a high-growth segment focused on doctors, dentists, group practices, 

surgery centers, medical office buildings and other healthcare entities.

Comerica, through the Retail Bank, was selected to serve as the financial agent for the U.S. 

Department of Treasury’s myRA program. The myRA program is a retirement savings program 

targeting  low-  to  moderate-income  Americans  who  do  not  have  access  to  employer-sponsored 

retirement savings plans.

Wealth Management provides us the ability to bring private banking, investment management, 

and fiduciary solutions to our Business Bank and Retail Bank customers. Our target customers 

include business owners, corporate executives, first generation wealth, foundations and institutions.

A  key  strength  of  Comerica  is  working  with  business  owners  to  address  the  needs  of  their 

businesses, as well as their personal wealth goals. Our Business Owner Advisory Services group 

within Wealth Management, partnering with the Business Bank, has had impressive results, bringing 

in some $1 billion in new balances in 2014, and nearly $2 billion since its inception in 2012.

Also  within  Wealth  Management  is  our  Professional  Trust  Alliance,  which  we  established 

almost  20  years  ago.  We  have  agreements  with  third-party  broker-dealers  to  provide  trust 

administration  and  investment  monitoring  for  their  clients.  We  continue  to  build  this  business 

and currently have agreements with 13 broker-dealers. This business has become a significant 

contributor  to  increasing  our  fiduciary  income.  We  have  grown  the  assets  under  management 

related to these alliances considerably over the past two years. At present, we have 14 offices 

throughout  the  United  States  dedicated  to  serving  and  building  our  Professional  Trust  Alliance 

business.

Our Corporate Marketing area continues to facilitate the adoption of the Comerica Promise 

in partnership across all of our business lines. The new “Promise” branding can be seen in many 

of our printed materials, including this annual report, as well as in our advertising. At the heart 

of  the  Comerica  Promise,  which  is  aimed  at  raising  expectations  of  what  a  bank  can  be,  are 

our core values of Customer-centricity, Collaboration, Integrity, Excellence, Agility, Diversity, and 

Involvement. The response to the Promise campaign from customers and colleagues has been 

positive and enthusiastic.

Ongoing Commitment to Sustainability, Community and Diversity

Comerica continues to be recognized for its commitment to sustainability. In 2014, we were 

listed for a second consecutive year on the CDP Carbon Performance Leadership Index and were 

one of the top-ranked U.S. banks in the Newsweek Green Rankings. Comerica also received a 

Green Supply Chain award from the Supply & Demand Chain Executive Magazine, was the only 

U.S. bank listed as a Greenbiz Natural Capital Efficiency Leader, and continued its listing on the 

FTSE4Good and Thomson Reuters Corporate Responsibility indices.

shred days, where Comerica helped individuals and businesses discard documents safely and 

sustainably. The secure shredding of these documents supported our commitments to reduce the 

potential for identity theft from improper disposal of sensitive documents and to safely recycle the 

waste paper.

Comerica’s commitment to the community also can be seen in our charitable contributions, 

and employee giving and volunteerism. In 2014, Comerica contributed more than $8.5 million to 

nonprofit organizations within our markets. Our employees raised some $2.2 million for the United 

Way and Black United Fund.  In addition, our employees donated their personal time and talents 

– more than 73,000 hours, far exceeding our goal – back to the communities where they live and 

work, including on our National Days of Service, when some 54 projects were held.

In Dallas, we formed a partnership in 2014 with Dallas Children’s Advocacy Center (DCAC) to 

help the nonprofit provide backpacks, school supplies, uniforms and personal effects to children 

who  might  have  otherwise  started  the  school  year  without  these  essentials.  In  our  first  year  of 

sponsoring the social media-driven effort, we helped the nonprofit raise more than $40,000 and 

provide more than 900 backpacks to DCAC clients and their siblings.

Helping to provide school supplies for low- to moderate-income students has been a priority 

in a number of our markets for several years. In California, we participated in backpack drives in 

the Bay Area, Los Angeles and San Diego.

Comerica  continues  to  sponsor  the  Comerica  Hatch  Detroit  Contest,  which    seeks  ideas 

for new retail businesses in Detroit. In 2014, Comerica again provided the grand prize award. A 

similar contest was held for the first time in North Texas with the Dallas Entrepreneur Center, with 

positive results.

We awarded a grant in Michigan to the City of Ferndale Police Department, winner of the 

grand  prize  in  our  Home  of  the  Brave  National  Anthem  Facebook  Contest.  Ferndale  Detective 

Brendan Moore won the grant for his department and the opportunity to sing the National Anthem 

at Comerica Park, home of the Detroit Tigers.

At Comerica, we celebrate the differences among our colleagues and customers, with the 

understanding that such differences make us a stronger company. That is why we are so grateful 

and  honored  to  receive  recognition  in  2014  for  our  focus  on  diversity.  For  example,  Comerica 

was once again ranked among the top five in the DiversityInc “Top 10 Regional Companies for 

Diversity.” LATINA Style Magazine recognized our bank, once again, as being among the “50 Best 

Companies  for  Latinas  to  Work  for  in  the  U.S.”  Digital  media  company  DailyWorth  recognized 

Comerica  for  being  among  the  “25  Best  Companies  to  Work  for  if  You  are  a  Woman.”  And, 

Comerica earned a perfect rating of 100 percent on the Human Rights Campaign 2014 Corporate 

Equality Index, a national benchmarking survey and report on corporate policies and practices 

related to LGBT workplace equality.

and  fourth  among  noncustomers  in  the  American  Banker /Reputation  Institute  survey  of  bank 

reputations. We certainly appreciate all of the positive recognition.

Looking Ahead

Looking ahead, we believe we are well positioned for 2015 and beyond. We remain focused 

on the long term and the things we can control, such as growing loans and deposits along with 

managing our expenses. We are in the right markets with the right products and services, and with 

the right people, who remain focused on building enduring customer relationships.

We  plan  to  stay  with  our  relationship  banking  strategy,  which  has  served  us  well  through 

many cycles. This is not the time to reach, so we plan to maintain our pricing and credit discipline.

We  will  continue  to  manage  through  the  headwinds  arising  from  the  continuing  low-rate 

environment, declining purchase accounting accretion, and increasing regulatory and technology 

demands. We expect that as the economy continues to improve and the potential for a rate-rise 

nears, our revenue picture looks brighter.

In  short,  our  conservative,  consistent  approach  to  banking  –  which  includes  credit 

management,  investment  strategy,  capital  position,  and  focus  on  building  relationships  –  has 

positioned us well for the future.

We remain committed to providing attractive long-term returns for you, our shareholders.

Item 1. Business.

GENERAL

Comerica Incorporated (“Comerica”) is a financial services company, incorporated under the laws of the State of Delaware, 
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. Comerica was formed in 1973 to acquire the outstanding common stock of Comerica Bank, which at such time was 
a Michigan banking corporation and one of Michigan's oldest banks (formerly Comerica Bank-Detroit). On October 31, 2007, 
Comerica  Bank,  a  Michigan  banking  corporation,  was  merged  with  and  into  Comerica  Bank,  a  Texas  banking  association 
(“Comerica Bank”). As of December 31, 2014, Comerica owned directly or indirectly all the outstanding common stock of 2 active 
banking and 40 non-banking subsidiaries. At December 31, 2014, Comerica had total assets of approximately $69.2 billion, total 
deposits of approximately $57.5 billion, total loans (net of unearned income) of approximately $48.6 billion and shareholders’ 
equity of approximately $7.4 billion.

Business Segments

Comerica has strategically aligned its operations into three major business segments: the Business Bank, the Retail Bank, 
and Wealth Management. In addition to the three major business segments, Finance is also reported as a segment. We provide 
information  about  our  business  segments  in  Note 22  on  pages F-101  through  F-105  of  the  Notes  to  Consolidated  Financial 
Statements located in the Financial Section of this report.

Comerica operates in three primary geographic markets - Texas, California, and Michigan, as well as in Arizona and 
Florida, with select businesses operating in several other states, and in Canada and Mexico. We provide information about our 
market segments in Note 22 on pages F-101 through F-105 of the Notes to Consolidated Financial Statements located in the 
Financial Section of this report.  

Activities with customers domiciled outside the U.S., in total or with any individual country, are not significant. We 
provide information on risks attendant to foreign operations: (1) under the caption “Concentration of Credit Risk” on pages F-26 
through F-27 of the Financial Section of this report; and (2) under the caption "International Exposure" on page F-29 of the 
Financial Section of this report.

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-Fully Taxable Equivalent (FTE)” on page F-6 of 
the Financial Section of this report; (2) under the caption “Net Interest Income” on pages F-7 through F-8 of the Financial Section 
of this report; and (3) under the caption “Noninterest Income” on pages F-8 through F-9 of the Financial Section of this report. 

Acquisition of Sterling Bancshares, Inc.

On July 28, 2011, Comerica acquired all the outstanding common stock of Sterling Bancshares, Inc. ("Sterling"), a bank 
holding company headquartered in Houston, Texas, in a stock-for-stock transaction. Sterling common shareholders and holders 
of outstanding Sterling phantom stock units received 0.2365 shares of Comerica's common stock in exchange for each share of 
Sterling common stock or phantom stock unit. As a result, Comerica issued approximately 24 million common shares with an 
acquisition date fair value of $793 million, based on Comerica's closing stock price of $32.67 on July 27, 2011. Based on the 
merger agreement, outstanding and unexercised options to purchase Sterling common stock were converted into fully vested 
options  to  purchase  common  stock  of  Comerica.  In  addition,  outstanding  warrants  to  purchase  Sterling  common  stock  were 
converted into warrants to purchase common stock of Comerica. Including an insignificant amount of cash paid in lieu of fractional 
shares, the fair value of total consideration paid was $803 million. The acquisition of Sterling significantly expanded Comerica's 
presence in Texas, particularly in the Houston and San Antonio areas. 

COMPETITION

The financial services business is highly competitive. Comerica and its subsidiaries mainly compete in their three primary 
geographic markets of Texas, California and Michigan, as well as in the states of Arizona and Florida. They also compete in 
broader, national geographic markets, as well as markets in Mexico and Canada. They are subject to competition with respect to 
various products and services, including, without limitation, loans and lines of credit, deposits, cash management, capital market 
products, international trade finance, letters of credit, foreign exchange management services, loan syndication services, consumer 
lending,  consumer  deposit  gathering  and  mortgage  loan  origination,  consumer  products,  fiduciary  services,  private  banking, 
retirement services, investment management and advisory services, investment banking services, brokerage services, the sale of 
annuity products, and the sale of life, disability and long-term care insurance products. 

Comerica competes in terms of products and pricing with large national and regional financial institutions and with 
smaller financial institutions. Some of Comerica's larger competitors, including certain nationwide banks that have a significant 

1

 
presence in Comerica's market area, may make available to their customers a broader array of product, pricing and structure 
alternatives and, due to their asset size, may more easily absorb loans in a larger overall portfolio. Some of Comerica's smaller 
competitors may have more liberal lending policies and processes. Further, Comerica's banking competitors may be subject to a 
significantly different or reduced degree of regulation due to their asset size or types of products offered. They may also have the 
ability to more efficiently utilize resources to comply with regulations or may be able to more effectively absorb the costs of 
regulations into their existing cost structure. Comerica believes that the level of competition in all geographic markets will continue 
to increase in the future. 

 In addition to banks, Comerica's banking subsidiaries also face competition from other financial intermediaries, including 
savings and loan associations, consumer 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, with consumers having the opportunity to select from a growing variety of traditional and nontraditional alternatives. 
The  ability  of  non-banking  financial  institutions  to  provide  services  previously  limited  to  commercial  banks  has  intensified 
competition. Because non-banking financial institutions 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. 

In addition, the industry continues to consolidate, which affects competition by eliminating some regional and local 

institutions, while strengthening the franchises of acquirers.

SUPERVISION AND REGULATION

Banks, bank holding companies, and 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 (“FRB”) 
under the Bank Holding Company Act of 1956, as amended. The Gramm-Leach-Bliley Act expanded the activities in which a 
bank holding company registered as a financial holding company can engage. The conditions to be a financial holding company 
include, among others, the requirement that each depository institution subsidiary of the holding company be well capitalized and 
well managed. Effective July 2011, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) 
also requires the well capitalized and well managed standards to be met at the financial holding company level. Comerica became 
a financial holding company in 2000. As a financial holding company, Comerica may affiliate with securities firms and insurance 
companies, and engage in 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, including restrictions set forth in the Volcker Rule, described under the heading "The Dodd-Frank Wall 
Street Reform and Consumer Protection Act and Other Recent Legislative and Regulatory Developments" below); insurance 
underwriting and agency; merchant banking; and activities that the FRB has determined to be financial in nature or incidental or 
complementary to a financial activity, provided that it does not pose a substantial risk to the safety or soundness of the depository 
institution or the financial system generally. A bank holding company that is not also a financial holding company is limited to 
engaging in banking and other activities previously determined by the FRB to be closely related to banking.

Comerica 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. Comerica 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 Federal Reserve Bank of Dallas. Comerica Bank & 
Trust,  National Association  is  chartered  under  federal  law  and  is  subject  to  supervision  and  regulation  by  the  Office  of  the 
Comptroller of the Currency (“OCC”) under 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. The deposits of Comerica Bank and Comerica Bank & 
Trust, National Association are insured by the Deposit Insurance Fund of the Federal Deposit Insurance Corporation (“FDIC”) to 
the extent provided by law. In Canada, Comerica Bank is supervised by the Office of the Superintendent of Financial Institutions.

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 (in the case of Comerica Securities, Inc.), the 
Office of Financial and Insurance Regulation of the State of Michigan (in the case of Comerica Securities, Inc. and Comerica 
Insurance Services, Inc.), and the Securities and Exchange Commission (“SEC”) (in the case of Comerica Securities, Inc., World 
Asset Management, Inc. and Wilson, Kemp & Associates, Inc.). 

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. 

2

Requirements for Approval of Acquisitions and Activities 

In most cases, no FRB approval is required for Comerica 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. However, Federal and state laws impose 
notice and approval requirements for mergers and acquisitions of other depository institutions or bank holding companies. Prior 
approval is required before Comerica may acquire the beneficial ownership or control of more than 5% of the voting shares or 
substantially all of the assets of a bank holding company (including a financial holding company) or a bank. 

The  Community  Reinvestment Act  of  1977  (“CRA”)  requires  U.S.  banks  to  help  serve  the  credit  needs  of  their 
communities. Comerica Bank's current rating under the “CRA” is “satisfactory”. If any subsidiary bank of Comerica were to 
receive a rating under the CRA of less than “satisfactory,” Comerica would be prohibited from engaging in certain activities. 

In addition, Comerica, Comerica Bank and Comerica Bank & Trust, National Association, are each “well capitalized” 
and “well managed” under FRB standards. If any subsidiary bank of Comerica were to cease being “well capitalized” or “well 
managed” under applicable regulatory standards, the FRB could place limitations on Comerica's ability to conduct the broader 
financial activities permissible for financial holding companies or impose limitations or conditions on the conduct or activities of 
Comerica or its affiliates. If the deficiencies persisted, the FRB could order Comerica 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 
Comerica could elect to conform its non-banking activities to those permissible for a bank holding company that is not also a 
financial holding company. 

Further, the effectiveness of Comerica and its subsidiaries in complying with anti-money laundering regulations (discussed 

below) is also taken into account by the FRB when considering applications for approval of acquisitions.

Transactions with Affiliates

Various governmental requirements, including Sections 23A and 23B of the Federal Reserve Act and the FRB's Regulation 
W, limit borrowings by Comerica and its nonbank subsidiaries from its affiliate insured depository institutions, and also limit 
various other  transactions between  Comerica and its  nonbank subsidiaries, 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 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 a loan or extension of credit, as well as a purchase of securities issued by an affiliate, a purchase of assets (unless 
otherwise exempted by the FRB) from the affiliate, the acceptance of securities issued by the affiliate as collateral for a loan, and 
the issuance of a guarantee, acceptance or letter of credit on behalf of an affiliate. 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. The Dodd-Frank Act significantly expanded the coverage and scope of the limitations 
on affiliate transactions within a banking organization. For example, commencing in July 2012, the Dodd-Frank Act applies the 
10% of capital limit on covered transactions to financial subsidiaries and amends the definition of “covered transaction” to include 
(i) securities borrowing or lending transactions with an affiliate, and (ii) all derivatives 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.

Privacy

The privacy provisions of the Gramm-Leach-Bliley Act generally prohibit financial institutions, including Comerica, 
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. The Fair Credit Reporting Act restricts information 
sharing among affiliates for marketing purposes.

Anti-Money Laundering Regulations

The Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism 
Act  (“USA  PATRIOT Act”)  of  2001  and  its  implementing  regulations  substantially  broadened  the  scope  of  U.S.  anti-money 
laundering laws and regulations by requiring 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  USA 
PATRIOT Act and its 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.

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% of the total amount of deposits of 
insured depository institutions in the U.S. and no more than 30% of such deposits in that state (or such amount as established by 
state law if such amount is lower than 30%). 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, the “host” state must have “opted-in” to the Interstate Act by enacting a law permitting such branch purchases. The 
Dodd-Frank Act expanded the de novo interstate branching authority of banks beyond what had been permitted under the Interstate 
Act by eliminating the requirement that a state expressly “opt-in” to de novo branching, in favor of a rule that 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. Effective July 21, 2011, the Dodd-Frank Act also required that a bank holding company or 
bank be well capitalized and well managed (rather than simply adequately capitalized and adequately managed) in order to take 
advantage of these interstate banking and branching provisions.

Comerica has consolidated most of its banking business into one bank, Comerica Bank, with branches in Texas, Arizona, 

California, Florida and Michigan.

Dividends

Comerica is a legal entity separate and distinct from its banking and other subsidiaries. Most of Comerica's revenues 
result from dividends its bank subsidiaries pay it. There are statutory and regulatory requirements applicable to the payment of 
dividends by subsidiary banks to Comerica, as well as by Comerica to its shareholders. Certain, but not all, of these requirements 
are discussed below.

Comerica Bank and Comerica Bank & Trust, National Association 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 retained 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, 2015, Comerica's 
subsidiary banks could declare aggregate dividends of approximately $375 million from retained net profits of the preceding two 
years. Comerica's subsidiary banks declared dividends of $380 million in 2014, $480 million in 2013 and $497 million in 2012. 

Further, federal regulatory agencies can prohibit a banking institution or bank holding company from engaging in unsafe 
and unsound banking practices and could prohibit the payment of dividends under circumstances in which such payment could 
be  deemed  an  unsafe  and  unsound  banking  practice.  Under  the  Federal  Deposit  Insurance  Corporation  Improvement  Act 
(“FDICIA”), “prompt corrective action” regime discussed below, which applies to each of Comerica Bank and Comerica Bank 
& Trust, National Association, a subject bank is specifically prohibited from paying dividends to its parent company if payment 
would result in the bank becoming “undercapitalized.” In addition, Comerica Bank is also subject to limitations under Texas state 
law regarding the amount of earnings that may be paid out as dividends to its parent company, and requiring prior approval for 
payments of dividends that exceed certain levels.

Additionally, the payment of dividends by Comerica to its shareholders is subject to the non-objection of the FRB pursuant 
to the Comprehensive Capital Analysis and Review (CCAR) program. For more information, please see “The Dodd-Frank Wall 
Street Reform and Consumer Protection Act and Other Recent Legislative and Regulatory Developments” in this section.

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. 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.

Federal Deposit Insurance Corporation Improvement Act 

FDICIA  requires,  among  other  things,  the federal  banking  agencies to  take  “prompt corrective action”  in respect  of 
depository institutions that do not meet minimum capital requirements. FDICIA establishes five capital tiers: “well capitalized,” 
“adequately  capitalized,”  “undercapitalized,”  “significantly  undercapitalized”  and  “critically  undercapitalized.” A  depository 

4

institution's capital tier will depend upon where its capital levels are in relation to various relevant capital measures, which, among 
others, include a Tier 1 and total risk-based capital measure and a leverage ratio capital measure.

Regulations establishing the specific capital tiers provide that, for a depository institution to be well capitalized, it must 
have a total risk-based capital ratio of at least 10% and a Tier 1 risk-based capital ratio of at least 6%, a Tier 1 leverage ratio of at 
least 5% and not be subject to any specific capital order or directive. For an institution to be adequately capitalized, it must have 
a total risk-based capital ratio of at least 8%, a Tier 1 risk-based capital ratio of at least 4%, and a Tier 1 leverage ratio of at least 
4% (and in some cases 3%). Under certain circumstances, the appropriate banking agency may treat a well capitalized, adequately 
capitalized or undercapitalized institution as if the institution were in the next lower capital category.

As of December 31, 2014, Comerica and its banking subsidiaries exceeded the ratios required for an institution to be 

considered “well capitalized” under these regulations.

FDICIA generally prohibits a depository institution from making any capital distribution (including payment of a dividend) 
or  paying  any  management  fee  to  its  holding  company  if  the  depository  institution  would  thereafter  be  undercapitalized. 
Undercapitalized depository institutions are subject to limitations on growth and certain activities and are required to submit an 
acceptable capital restoration plan. The federal banking agencies may not accept a capital plan without determining, among other 
things, that the plan is based on realistic assumptions and is likely to succeed in restoring the depository institution's capital. In 
addition, for a capital restoration plan to be acceptable, the institution's parent holding company must guarantee for a specific time 
period that the institution will comply with such capital restoration plan. The aggregate liability of the parent holding company 
under the guaranty is limited to the lesser of (i) an amount equal to 5% of the depository institution's total assets at the time it 
became undercapitalized, or (ii) the amount that is necessary (or would have been necessary) to bring the institution into compliance 
with all capital standards applicable with respect to such institution as of the time it fails to comply with the plan. If a depository 
institution fails to submit or implement an acceptable plan, it is treated as if it is significantly undercapitalized.

Significantly  undercapitalized  depository  institutions  are  subject  to  a  number  of  requirements  and  restrictions. 
Specifically, such a depository institution may be required to do one or more of the following, among other things: sell sufficient 
voting stock to become adequately capitalized, reduce the interest rates it pays on deposits, reduce its rate of asset growth, dismiss 
certain senior executive officers or directors, or stop accepting deposits from correspondent banks. Critically undercapitalized 
institutions are subject to the appointment of a receiver or conservator or such other action as the FDIC and the applicable federal 
banking agency shall determine appropriate.

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 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 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.

Capital Requirements

Comerica and its bank subsidiaries are subject to risk-based capital requirements and guidelines imposed by the FRB 

and/or the OCC.

For  this  purpose,  a  depository  institution's  or  holding  company's  assets  and  certain  specified  off-balance  sheet 
commitments are assigned to four risk categories, each weighted differently based on the level of credit risk that is ascribed to 
such assets or commitments. A depository institution's or holding company's capital, in turn, is divided into two tiers: core (“Tier 1”) 
capital,  which  includes  common  equity,  non-cumulative  perpetual  preferred  stock,  a  limited  amount  of  cumulative  perpetual 
preferred  stock  and  related  surplus  (excluding  auction  rate  issues)  and  minority  interests  in  equity  accounts  of  consolidated 
subsidiaries, less goodwill, certain identifiable intangible assets and certain other assets; and supplementary (“Tier 2”) capital, 
which includes, among other items, perpetual preferred stock not meeting the Tier 1 definition, mandatory convertible securities, 
subordinated debt, and allowances for loan and lease losses, subject to certain limitations, less certain required deductions. Bank 
holding companies that engage in trading activities, whose trading activities exceed specified levels, also are required to maintain 
capital 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 maintains additional capital for market risk as required. 

5

Comerica, like other bank holding companies, currently is required to maintain Tier 1 and “total capital” (the sum of 
Tier 1 and Tier 2 capital) equal to at least 4% and 8% of its total risk-weighted assets (including certain off-balance-sheet items, 
such as standby letters of credit), respectively. At December 31, 2014, Comerica met both requirements, with Tier 1 and total 
capital equal to 10.50% and 12.51% of its total risk-weighted assets, respectively.

Comerica is also required to maintain a minimum “leverage ratio” (Tier 1 capital to non-risk-adjusted total assets) of 3% 
to 4%, depending upon criteria defined and assessed by the FRB. Comerica's leverage ratio of 10.35% at December 31, 2014 
reflects  the  nature  of  Comerica's  balance  sheet  and  demonstrates  a  commitment  to  capital  adequacy. At  December 31,  2014, 
Comerica Bank had Tier 1 and total capital equal to 10.36% and 12.02% of its total risk-weighted assets, respectively, and a 
leverage ratio of 10.20%. 

Additional information on the calculation of Comerica and its bank subsidiaries' Tier 1 capital, total capital and risk-
weighted assets is set forth in Note 20 of the Notes to Consolidated Financial Statements located on pages F-99 through F-100 of 
the Financial Section of this report. Additional information on the timing and nature of the Basel III capital requirements is set 
forth below, under "Basel III: Regulatory Capital and Liquidity Regime."

FDIC Insurance Assessments

The FDIC Deposit Insurance Fund (“DIF”) provides insurance coverage for certain deposits. 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, which was amended pursuant to the Federal Deposit Insurance Reform Act of 2005 and further amended by the Dodd-
Frank Act. The  Dodd-Frank Act  also  increased  the  DIF's  minimum  reserve  ratio  and  permanently  increased  general  deposit 
insurance coverage from $100,000 to $250,000. The final rule implementing revisions to the assessment system became effective 
April 1, 2011. Under the risk-based deposit premium assessment system, 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 
assessed quarterly. For 2014, Comerica’s FDIC insurance expense totaled $33 million. Our assessment rate could increase in the 
future under the current system if, for example, criticized loans and/or other higher risk assets increase or balance sheet liquidity 
decreases.

Enforcement Powers of Federal and State Banking Agencies

The FRB and other federal and state banking agencies have broad enforcement powers, including, without limitation, 
and as prescribed to each agency by applicable law, the power to 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.

Capital Purchase Program

On November 14, 2008, Comerica participated in the United States Department of the Treasury (“U.S. Treasury”) Capital 
Purchase Program by issuing to the U.S. Treasury, in exchange for aggregate consideration of $2.25 billion, (i) 2.25 million shares 
of Fixed Rate Cumulative Perpetual Preferred Stock, Series F, no par value (the “Series F Preferred Stock”), and (ii) a warrant to 
purchase 11,479,592 shares of Comerica's common stock at an exercise price of $29.40 per share that expires on November 14, 
2018    (the  “Warrant”).  Both  the  Series F  Preferred  Stock  and  the Warrant  were  accounted  for  as  components  of  Comerica's 
regulatory Tier 1 capital and contained terms and limitations imposed by the U.S. Treasury. On March 17, 2010, Comerica fully 
redeemed the Series F Preferred Stock previously issued to the U.S. Treasury, and Comerica exited the Capital Purchase Program. 
The Warrant was separated into 11,479,592 warrants to purchase one share of Comerica's common stock at an exercise price of 
$29.40 per share, and such warrants are now listed and traded on the NYSE. As a result of participating in the Capital Purchase 
Program, Comerica was subject to certain executive compensation and corporate governance standards promulgated by the U.S. 
Treasury prior to redemption, which no longer applied to Comerica following the redemption. 

The Dodd-Frank Wall Street Reform and Consumer Protection Act and Other Recent Legislative and Regulatory Developments

The recent financial crisis has led to significant changes in the legislative and regulatory landscape of the financial services 
industry, including the overhaul of that landscape with the passage of the Dodd-Frank Act, which was signed into law on July 21, 
2010. Provided below is an overview of key elements of the Dodd-Frank Act relevant to Comerica, as well as other recent legislative 
and  regulatory  developments. The  estimates  of  the  impact  on  Comerica  discussed  below  are  based  on  information  currently 
available and, if applicable, are subject to change until final rulemaking is complete.

Incentive-Based Compensation.  In June 2010, the FRB, OCC and FDIC issued comprehensive final guidance on incentive 
compensation policies 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 

6

 
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. Comerica is subject to this final guidance and, similar to 
other large banking organizations, 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. Further, 
it is the Company’s intent to continue to evolve our processes going forward by monitoring regulations and best practices for 
sound incentive compensation.

On April 14, 2011, the FRB, OCC and several other federal financial regulators issued a joint proposed rulemaking 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 
supplements the final guidance issued by the banking agencies in June 2010. Consistent with the Dodd-Frank Act, the proposed 
rule would not apply to institutions with total consolidated assets of less than $1 billion, and 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 that at least 50 percent of annual incentive-based payments be deferred over a period of at least three 
years for designated executives. Moreover, boards of directors of these larger institutions would be required to identify employees 
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, and to determine that the incentive compensation for these employees appropriately balances risk 
and rewards according to enumerated standards. Comerica is monitoring the development of this rule.

Basel III: Regulatory Capital and Liquidity Regime.  In December 2010, the Basel Committee on Banking Supervision 
(the “Basel Committee”) issued a framework for strengthening international capital and liquidity regulation (“Basel III”). In July 
2013, U.S. banking regulators issued a final rule for the U.S. adoption of the Basel III regulatory capital framework. The regulatory 
framework includes a more conservative definition of capital, two new capital buffers - a conservation buffer and a countercyclical 
buffer, new and more stringent risk weight categories for assets and off-balance sheet items, and a supplemental leverage ratio. 
As a banking organization subject to the standardized approach, the rules are effective for Comerica on January 1, 2015, with 
certain transition provisions fully phased in on January 1, 2018.

According to the rule, Comerica will be subject to the capital conservation buffer of 2.5 percent, when fully phased in, 
to avoid restrictions on capital distributions and discretionary bonuses. However, the rules do not subject Comerica to the capital 
countercyclical buffer of up to 2.5 percent or the supplemental leverage ratio. Comerica estimates the December 31, 2014 Tier 1 
and Tier 1 common risk-based ratio would be 10.3 percent if calculated under the final rule, as fully phased in, excluding most 
elements of accumulated other comprehensive income from regulatory capital. Comerica's December 31, 2014 estimated Tier 1 
common and Tier 1 capital ratios exceed the minimum required by the final rule (7 percent and 8.5 percent, respectively, including 
the fully phased-in capital conservation buffer). For a reconcilement of these non-GAAP financial measures, see page F-41 of the 
Financial Section of this report under the caption "Supplemental Financial Data."

On December 9, 2014, U.S. banking regulators proposed a rule that would establish an additional capital buffer for 
banking organizations deemed systemically important to the global financial system (globally systemically important bank holding 
companies, or “G-SIB”). Comerica would not be considered a G-SIB under the rule as proposed. 

On September 3, 2014, U.S. banking regulators adopted the Liquidity Coverage Ratio ("LCR") rule, which set for U.S. 
banks the minimum liquidity measure established under the Basel III liquidity framework. Under the final rule, Comerica is subject 
to a modified LCR standard, which requires a financial institution to hold a minimum level of high-quality, liquid assets ("HQLA") 
to fully cover net cash outflows under a 30-day systematic liquidity stress scenario. The rule is effective for Comerica on January 
1, 2016. During the transition year, 2016, Comerica will be required to maintain a minimum LCR of 90 percent. Beginning January 
1, 2017, and thereafter, the minimum required LCR will be 100 percent. Comerica continues to evaluate the impact of the rule; 
however, we expect to meet the final requirements adopted by U.S. banking regulators within the required timetable. To reach full 
compliance and provide a buffer for normal volatility in balance sheet dynamics, Comerica expects to add additional HQLA, 
which may be funded with additional debt, in the future. Comerica does not currently expect compliance with the LCR rule will 
have a significant impact on net interest income.

7

 
 
The Basel III liquidity framework includes a second minimum liquidity measure, the Net Stable Funding Ratio ("NSFR"), 
which requires the amount of available longer-term, stable sources of funding to be at least 100 percent of the required amount of 
longer-term stable funding over a one-year period. The Basel Committee on Banking Supervision is in the process of reviewing 
the proposed NSFR standard and evaluating its impact on the banking system. U.S. banking regulators have announced that they 
expect to issue proposed rulemaking to implement the NFSR in advance of its scheduled global implementation in 2018. While 
uncertainty exists in the final form and timing of the U.S. rule implementing the NSFR and whether or not Comerica will be subject 
to the full requirements, Comerica is closely monitoring the development of the rule. 

Interchange Fees.  On July 20, 2011, the FRB published final rules pursuant to the Dodd-Frank Act establishing the 
maximum permissible interchange fee that an issuer may receive for an electronic debit transaction as the sum of 21 cents per 
transaction and 5 basis points multiplied by the value of the transaction and prohibiting network exclusivity arrangements and 
routing restrictions. Comerica is subject to the final rules. In July 2013, a federal district court invalidated the FRB's interchange 
fee rules. The FRB's appeal of the court’s ruling resulted in the U.S. Circuit Court of Appeals for the District of Columbia overruling 
the district court, reinstating the final rule as previously issued. On January 20, 2015, the U.S. Supreme Court denied a further 
appeal. 

Supervision and Regulation Assessment.  Section 318 of the Dodd-Frank Act authorizes the federal banking agencies to 
assess fees against bank holding companies with total consolidated assets in excess of $50 billion equal to the expenses necessary 
or appropriate in order to carry out their supervision and regulation of those companies. We paid $1.5 million in 2014 with respect 
to the 2013 assessment year and accrued another $1.5 million for the 2014 assessment year. 

The Volcker Rule. The federal banking agencies and the SEC published approved joint final regulations to implement 
the Volcker Rule on December 10, 2013. The Volcker Rule generally prohibits banking entities from engaging in proprietary 
trading and from owning and sponsoring "covered funds" (e.g. hedge funds and private equity funds). The final regulations adopt 
a multi-faceted approach to implementing the Volcker Rule prohibitions that relies on: (i) detailed descriptions of prohibited and 
permitted activities; (ii) detailed compliance requirements; and (iii) for banking entities with large volumes of trading activity, 
detailed quantitative analysis and reporting obligations. In addition to rules implementing the core prohibitions and exemptions 
(e.g. underwriting, market-making related activities, risk-mitigating hedging and trading in certain government obligations) of the 
Volcker  Rule,  the  regulations  also  include  two  appendices  devoted  to  record-keeping  and  reporting  requirements,  including 
numerous quantitative data reporting obligations for banking entities with significant trading activities (Appendix A) and enhanced 
compliance requirements for banking entities with significant trading or covered fund activities (Appendix B). The final rule was 
effective April 1, 2014. The Volcker Rule generally requires full compliance with the new restrictions by July 21, 2015; however, 
the FRB has recently extended the conformance period to July 21, 2017 for covered funds that were in place prior to December 
31,  2013.  Comerica  expects  to  meet  the  final  requirements  adopted  by  regulators  within  the  applicable  regulatory  timelines. 
Additional information on Comerica's portfolio of indirect (through funds) private equity and venture capital investments is set 
forth in Note 1 of the Notes to Consolidated Financial Statements located on page F-51 of the Financial Section of this report. 

Annual Capital Plans and Stress Tests. Comerica is subject to the FRB’s annual Comprehensive Capital Analysis and 
Review (CCAR) process, as well as the Dodd-Frank Act Stress Testing (DFAST) requirements. As part of the CCAR process, the 
FRB undertakes a supervisory assessment of the capital adequacy of bank holding companies (BHCs), including Comerica, that 
have $50 billion or more in total consolidated assets. This capital adequacy assessment is based on a review of a comprehensive 
capital plan submitted by each participating BHC to the FRB that describes the company’s planned capital actions during the nine 
quarter review period, as well as the results of stress tests conducted by both the company and the FRB under different hypothetical 
macro-economic scenarios, including a supervisory baseline and an adverse and a severely adverse scenario provided by the FRB. 
After completing its review, the FRB may object or not object to the company’s proposed capital actions, such as plans to pay or 
increase common stock dividends, reinstate or increase common stock repurchase programs, or redeem preferred stock or other 
regulatory capital instruments. In connection with the 2014 CCAR, Comerica submitted its 2014 capital plan to the FRB on January 
3, 2014; on March 26, 2014, Comerica announced that the FRB had completed its CCAR 2014 capital plan review and did not 
object to the capital plan or capital distributions contemplated in the plan. Also as required, Comerica submitted its CCAR 2015 
capital plan to the FRB on January 5, 2015 and expects to receive the results of the FRB's review of the plan in March 2015. 

As part of the CCAR and DFAST process, both the FRB and Comerica release certain revenue, loss and capital results 
from their stress testing exercises, generally in March of each year. FRB regulations also require that Comerica and other large 
bank holding companies conduct a separate mid-year stress test using financial data as of March 31st and three company-derived 
macro-economic scenarios (base, adverse and severely adverse) and publish a summary of the results under the severely adverse 
scenario in September.  On March 20, 2014 and September 15, 2014, Comerica released the results of its company-run annual 
and  mid-year  stress  tests,  respectively,  which  are  available  in  the  Investor  Relations  section  of  Comerica's  website  at 
investor.comerica.com, on the “Dodd-Frank Act Stress Test Results” page under "Financial Reports." Similar timelines will be 
expected for the 2015 mid-year stress tests.  

In October 2014, the FRB modified the timing of the capital planning cycle. For 2016, the annual capital plan will be 
moved to an April submission (instead of January) and the mid-year stress test will be moved to an October submission (instead 

8

 
 
 
of July). Accordingly, for the 2015 Capital Plan submission, the FRB’s determination regarding capital distributions will extend 
over a period of five quarters, 2Q 2015 - 2Q 2016, in order to accommodate the shift in the capital plan cycle in 2016.

Enhanced Prudential Requirements.  The Dodd-Frank Act created the Financial Stability Oversight Council (“FSOC”) 
to coordinate efforts of the primary U.S. financial regulatory agencies in establishing regulations to address financial stability 
concerns and to make recommendations to the FRB as to enhanced prudential standards that must apply to large, interconnected 
bank holding companies and nonbank financial companies supervised by the FRB under the Dodd-Frank Act, including capital, 
leverage, liquidity and risk management requirements.

On  February  18,  2014,  the  FRB  issued  its  final  regulations  to  implement  the  enhanced  prudential  and  supervisory 
requirements  mandated  by  the  Dodd-Frank  Act.  The  final  regulations  address  enhanced  risk-based  capital  and  leverage 
requirements, enhanced liquidity requirements, enhanced risk management and risk committee requirements, single-counterparty 
credit limits, semiannual stress tests (as described above under "Annual Capital Plans and Stress Tests"), and a debt-to-equity limit 
for companies determined to pose a grave threat to financial stability. They are intended to allow regulators to more effectively 
supervise large bank holding companies and nonbank financial firms whose failure could impact the stability of the US financial 
system, and generally build on existing US and international regulatory guidance. The proposal also takes a multi-stage or phased 
approach to many of the requirements (such as the capital and liquidity requirements). Most of these requirements apply to Comerica 
because it has consolidated assets of more than $50 billion. Comerica has or will implement all requirements of the new rules 
within regulatory timelines.

Resolution  (Living Will)  Plans.    Section  165(d)  of  the  Dodd-Frank Act  requires  bank  holding  companies  with  total 
consolidated assets of $50 billion or more (“covered companies”) to prepare and submit to the federal banking agencies (e.g., FRB 
and FDIC) a plan for their rapid and orderly resolution under the U.S. Bankruptcy Code. Covered companies, such as Comerica, 
with less than $100 billion in total nonbank assets were required to submit their initial plans by December 31, 2013. In addition, 
Section 165(d) requires FDIC-insured depository institutions (like Comerica Bank) with assets of $50 billion or more to develop, 
maintain, and periodically submit plans outlining how the FDIC would resolve it through the FDIC's resolution powers under the 
Federal Deposit Insurance Act. The federal banking agencies have issued rules to implement these requirements. In addition, those 
rules require the filing of annual updates to the plans. Both Comerica and Comerica Bank filed their respective initial and updated 
resolution plans by the required due dates. The resolution plans are currently under review by the FRB and FDIC. 

Section 611 and Title VII of the Dodd-Frank Act.  Section 611 of the Dodd-Frank Act prohibits a state bank from engaging 
in derivative transactions unless the lending limit laws of the state in which the bank is chartered take into consideration exposure 
to derivatives. Section 611 does not provide how state lending limit laws must factor in derivatives. The Texas Finance Commission 
has adopted an administrative rule meeting the requirements of Section 611. Accordingly, Comerica Bank may engage in derivative 
transactions, as permitted by applicable law.

Title  VII  of  the  Dodd-Frank Act  establishes  a  comprehensive  framework  for  over-the-counter  (“OTC”)  derivatives 
transactions. The structure for derivatives set forth in the Dodd-Frank Act is intended to promote, among other things, exchange 
trading and centralized clearing of swaps and security-based swaps, as well as greater transparency in the derivatives markets and 
enhanced monitoring of the entities that use these markets. In this regard, the CFTC and SEC have issued several regulatory 
proposals, some of which are now effective or will become effective in 2015. 

The SEC and CFTC have jointly adopted rules further defining the terms “swap,” “security-based swap,” “security-based 
swap agreement,” and have also adopted final joint rules defining the terms “swap dealer,” “security-based swap dealer,” “major 
swap participant,” and “major security-based swap participant.”  Comerica has determined that neither it, nor its subsidiaries, are 
within the definition of “swap dealer” or “major swap participant,” but some portions of the Title VII regulations apply nonetheless. 
One of these regulations centers on limiting certain OTC transactions to “eligible contract participants.”  This regulation may have 
an impact on the small business customers of Comerica's banking subsidiaries by making such customers ineligible for swap 
derivatives as hedging in their loan agreements.

Consumer Finance Regulations.   The Dodd-Frank Act made several changes to consumer finance laws and regulations. 
It contained provisions that have weakened the federal preemption rules applicable for national banks and give state attorneys 
general the ability to enforce federal consumer protection laws. Additionally, the Dodd-Frank Act created the Consumer Financial 
Protection Bureau (“CFPB“), which has a broad rule-making authority for a wide range of consumer protection laws that apply 
to all banks and savings institutions, including the authority to prohibit “unfair, deceptive or abusive” acts and practices, and 
possesses examination and enforcement authority over all banks and savings institutions with more than $10 billion in assets. In 
this regard, the CFPB has commenced issuing several new rules to implement various provisions of the Dodd-Frank Act that were 
specifically identified as being enforced by the CFPB, as well as those specified for supervisory and enforcement authority for 
very large depository institutions and non-depository (nonbank) entities. Comerica is subject to CFPB foreign remittance rules 
and home mortgage lending rules, in addition to certain other CFPB rules.

The foreign remittance rules fall under Section 1073 of the Dodd-Frank Act. The CFPB issued new regulations amending 
Regulation E, which implements the Electronic Fund Transfer Act, effective October 28, 2013. The regulations were designed to 

9

provide protections to consumers who transfer funds to recipients located in countries outside the United States (customer foreign 
remittance transfers). In general, the regulation requires remittance transfer providers, such as Comerica, to disclose to a consumer 
the exchange rate, fees, and amount to be received by the recipient when the consumer sends a remittance transfer. Although 
Comerica had implemented the model disclosures provided in Appendix A to the final rule, on September 18, 2014, the CFPB 
extended the compliance exception period for the rule's new disclosure requirements to July 21, 2020. 

On July 17, 2014, the CFPB issued an interpretive rule clarifying that where a successor-in-interest (successor) who has 
previously acquired title to a dwelling agrees to be added as obligor or substituted for the existing obligor on a consumer credit 
transaction secured by that dwelling, the creditor's written acknowledgment of the successor as obligor is not subject to the CFPB’s 
Ability-to-Repay Rule because such a transaction does not constitute an assumption as defined by Regulation Z. In addition, the 
CFPB issued other Regulation Z-related rules that had little or no effect on Comerica’s operations as it has outsourced most of its 
consumer loan origination and servicing.

On November 13, 2014, the CFPB issued a proposed regulation establishing new consumer protections and disclosure 
requirements on prepaid accounts, including (i) the provision of either periodic statements or free online account information 
access; (ii) new account error and unauthorized transaction rights; (iii) new “Know Before You Owe” prepaid account disclosures; 
(iv) public disclosure of account agreements for prepaid accounts and (v) credit protection for linked credit accounts. 

Comerica is monitoring the development of these new rules and will position itself to be in compliance with any new 

requirements within the established regulatory time frames.

Truth in Lending Act. As a result of recent judicial decisions, borrowers are permitted to rescind their mortgage pursuant 
to the Truth in Lending Act by giving notice of their intent to rescind within three years of closing, and do not need to file suit to 
exercise this right.  This decision could impact Comerica’s indemnity rights with its mortgage servicing vendor, as well as consumer 
closed-end mortgage loans held in Comerica’s portfolio; however, such impact is not anticipated to be significant.

FDIC Guidance on Brokered Deposits.  On January 5, 2015, the FDIC issued guidance in the form of “Frequently Asked 
Questions” to promote consistency by insured depository institutions in identifying, accepting, and reporting brokered deposits.  
All insured depository institutions (including those that are well capitalized) must report brokered deposits in their Consolidated 
Reports of Condition and Income (Call Reports).  Comerica is currently evaluating the impact of these FAQs to various business 
units throughout the organization.  

Flood Insurance Reform.  The Biggert-Waters Flood Insurance Reform Act of 2012 (“Biggert-Waters Act”), as amended 
by the Homeowner Flood Insurance Affordability Act of 2014, modified the National Flood Insurance Program by: (i) increasing 
the maximum civil penalty for Flood Disaster Protection Act violations to $2,000 and eliminating the annual penalty cap; (ii) 
requiring certain lenders (including Comerica) to escrow premiums and fees for flood insurance on residential improved real 
estate; (iii) directing lenders to accept private flood insurance and to notify borrowers of its availability; (iv) amending the force 
placement requirement provisions; and (v) permitting lenders to charge borrowers costs for lapses in or insufficient coverage. 
These requirements will impact Comerica loans and extensions of credit secured with residential improved real estate. The civil 
penalty and force placed insurance provisions were effective immediately.  

On October 21, 2014, certain federal agencies issued a joint proposed rule exempting: (1) detached structures that are 
not used as a residence from the mandatory flood insurance purchase requirements and (2) HELOCs, business purpose loans, 
nonperforming loans, loans with terms of less than one year, loans for co-ops and condominiums, and subordinate loans on the 
same property from the mandatory escrow of flood insurance premium requirements. Additionally, the proposed rule would require 
Comerica to offer the option to escrow flood insurance premiums starting on January 1, 2016. The federal agencies will address 
the remaining provisions of the Biggert-Waters Act in a separate rulemaking. Comerica will continue to monitor the development 
and implementation of these rules.

Future Legislation and Regulatory Measures

The environment in which financial institutions will operate after the recent financial crisis, including legislative and 
regulatory changes affecting capital, liquidity, supervision, permissible activities, corporate governance and compensation, and 
changes in fiscal policy, may have long-term effects on the business model and profitability of financial institutions that cannot  
be foreseen. Moreover, in light of recent events and current conditions in the U.S. financial markets and economy, Congress and 
regulators have continued to increase their focus on the regulation of the financial services industry. Comerica cannot accurately 
predict whether legislative changes will occur or, if they occur, the ultimate effect they would have upon the financial condition 
or results of operations of Comerica.

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 

10

 
 
 
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-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 Administration 

Comerica maintains a Credit Administration Department (“Credit Administration”) which is responsible for the oversight 
and monitoring of our loan portfolio. Credit Administration assists with underwriting by providing objective financial analysis, 
including an assessment of the borrower's business model, balance sheet, cash flow and collateral. Each borrower relationship is 
assigned an internal risk rating by Credit Administration. Further, Credit Administration updates the assigned internal risk rating 
for every borrower relationship as new information becomes available, either as a result of periodic reviews of the credit quality 
or as a result of a change in borrower performance. The goal of the internal risk rating framework is to improve 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.

Credit Policy

Comerica maintains a comprehensive set of credit policies. Comerica's credit policies provide individual relationship 
managers, as well as loan committees, approval authorities based on our internal risk rating system and establish maximum exposure 
limits based on risk ratings and Comerica's legal lending limit. Credit Administration, in conjunction with the businesses units, 
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 comprising 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.

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

The pro-forma 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 our Energy loan portfolio, please see the caption, “Energy Lending” on pages F-28 

through F-29 of 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 both 
loans to real estate developers and loans secured by owner-occupied real estate. Comerica's CRE loan underwriting policies are 

11

 
 
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.

Consumer and Residential Mortgage Loan Portfolios

Comerica's consumer and residential mortgage loans are originated consistent with the underwriting approach described 
above, but also 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. Comerica 
does  not  originate  subprime  loan  programs. 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. We generally consider 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. 

EMPLOYEES

As of December 31, 2014, Comerica and its subsidiaries had 8,499 full-time and 616 part-time employees.

Item 1A.  Risk Factors.

This report includes forward-looking statements as defined in the Private Securities Litigation Reform Act of 1995. In 
addition, Comerica may make other written and oral communications from time to time that contain such statements. All statements 
regarding Comerica's expected financial position, strategies and growth prospects and general economic conditions Comerica 
expects to exist in the future are forward-looking statements. The words, “anticipates,” “believes,” “feels,” “expects,” “estimates,” 
“seeks,” “strives,” “plans,” “intends,” “outlook,” “forecast,” “position,” “target,” “mission,” “assume,” “achievable,” “potential,” 
“strategy,” “goal,” “aspiration,” "opportunity," "initiative," “outcome,” “continue,” “remain,” “maintain,” "on course," “trend,” 
“objective,” "looks forward," "projects," "models" and variations of such words and similar expressions, or future or conditional 
verbs such as “will,” “would,” “should,” “could,” “might,” “can,” “may” or similar expressions, as they relate to Comerica or its 
management, are intended to identify forward-looking statements.

Comerica cautions that forward-looking statements are subject to numerous assumptions, risks and uncertainties, 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, 
12

could cause actual results to differ materially from forward-looking statements, and future results could differ materially from 
historical performance.

• 

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

Local,  domestic,  and  international  economic,  political  and  industry  specific  conditions  affect  the  financial  services 
industry, directly and indirectly. Conditions such as or related to inflation, recession, unemployment, volatile interest 
rates, international conflicts and other factors, such as real estate values, energy prices, state and local municipal budget 
deficits, the recent European debt crisis and government spending and the U.S. national debt, outside of our control may, 
directly and indirectly, adversely affect Comerica. As has been the case with the impact of recent economic conditions, 
economic downturns could result in the delinquency of outstanding loans, which could have a material adverse impact 
on Comerica's earnings.

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 
and fiscal policies determine in a 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, will 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.

• 

Changes in regulation 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 SEC, FINRA and other regulatory bodies. Such regulation and supervision governs 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, 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 or supervisory action, may have a material adverse impact on Comerica's business, financial 
condition or results of operations. 

In particular, Congress and other regulators have significantly increased their focus on the regulation of the financial 
services industry. Their actions include, but are not limited to, the passage of the Dodd-Frank Act, many parts of which 
are now in effect, and the adoption of the Basel III framework in the U.S. For additional information on these actions, 
please  see    “The  Dodd-Frank  Wall  Street  Reform  and  Consumer  Protection Act  and  Other  Recent  Legislative  and 
Regulatory Developments” section of the “Supervisory and Regulation” section of this report. Many provisions in the 
Dodd-Frank Act and the Basel III framework remain subject to regulatory rule-making and/or implementation, the effects 
of which are not yet known. 

Additionally, Comerica may be subject to other regulatory actions that are currently under consideration, or may be under 
consideration  in  the  future.  For  example,  as  discussed  in  the  “The  Dodd-Frank  Wall  Street  Reform  and  Consumer 
Protection Act and Other Recent Legislative and Regulatory Developments” section of the “Supervisory and Regulation” 
section of this report, Comerica is not subject to the additional capital buffer for banking organizations deemed systemically 
important to the global financial system. However, should U.S. banking regulators establish an additional capital buffer 
for banking organizations deemed systemically important to the U.S. financial system, Comerica may be subject to an 
additional buffer. Further, the current administration proposed in January 2010 a fee on those financial institutions that 
benefited from recent actions taken by the U.S. government to stabilize the financial system. Calls for that fee were 
renewed during the 2013 federal budget discussions. Most recently, the administration's 2015 budget proposal would 
impose a 7 basis point tax on U.S. financial firms with assets over $50 billion, with the goal of such proposal to penalize 
financial institutions for being overly leveraged.  If such fee or another similar fee were implemented, Comerica would 
likely be subject to its terms.  

The effects of such legislation and regulatory actions on Comerica cannot reliably be fully determined at this time. We 
can neither predict when or whether future regulatory or legislative reforms will be enacted nor what their contents will 
be. The impact of any future legislation or regulatory actions on Comerica's businesses or operations cannot be reliably 
determined at this time, and such impact may adversely affect Comerica.

• 

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 or a lack of market or customer 
confidence in financial markets in general, which may result in a loss of customer deposits or outflows of cash or collateral 
and/or 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 the 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 our 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. 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.

In September 2014, U.S. banking regulators issued a final rule implementing a quantitative liquidity requirement in the 
U.S. generally consistent with the Liquidity Coverage Ratio (LCR) minimum liquidity measure established under the 
Basel III liquidity framework. Under the rule, Comerica will be required to hold a minimum level of high-quality, liquid 
assets (HQLA) to fully cover modified net cash outflows under a 30-day systematic liquidity stress scenario. The rule is 
effective for Comerica on January 1, 2016. During the transition year, 2016, Comerica will be required to maintain a 
minimum LCR of 90 percent. Beginning January 1, 2017, and thereafter, the minimum required LCR will be 100 percent. 
To reach full compliance and provide a buffer for normal volatility in balance sheet dynamics, Comerica expects to add 
additional HQLA, which may be funded with additional debt, in the future. For more information regarding the LCR, 
please see the “Supervision and Regulation” section of this report.  The inability to access capital markets funding sources 
as needed could adversely impact our level of regulatory-qualifying capital and ability to comply with the LCR framework.

Further, if Comerica is 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. 

• 

Compliance with more stringent capital and liquidity requirements may adversely affect Comerica.

New capital requirements in connection with Basel III and the requirements of the Dodd-Frank Act applicable to Comerica 
as  a  bank  holding  company  as  well  as  to  Comerica's  subsidiary  banks  will  have  an  effect  on  Comerica. Additional 
information on the regulatory capital requirements applicable to Comerica is set forth in the “Supervision and Regulation” 
section of this report. These requirements, and any other new laws or regulations, 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. 

The liquidity requirements applicable to Comerica as a bank holding company as well as to our subsidiary banks are in 
the process of being substantially revised, in connection with recent supervisory guidance, Basel III and the requirements 
of the Dodd-Frank Act. Additional information on the liquidity requirements applicable to Comerica is set forth in the 
“Supervision and Regulation” section of this report. In light of these or other new legal and regulatory requirements, 
Comerica and our subsidiary banks are, and will be in the future, required to satisfy additional, more stringent, liquidity 
standards, including, for the first time, quantitative standards for liquidity management. 

Further, our regulators may also require us to satisfy additional, more stringent capital adequacy and liquidity standards 
than those specified as part of the Dodd-Frank Act and the FRB's proposed and final rules implementing Basel III, or 
comply with the requirements of these standards earlier than might otherwise be required, in connection with the annual 
CCAR process.

The ultimate impact of the new capital and liquidity standards cannot be fully determined at this time and will depend 
on a number of factors, including treatment and implementation by the U.S. banking regulators. However, maintaining 
higher levels of capital and liquidity may reduce Comerica's profitability and otherwise adversely affect its business, 
financial condition, or results of operations. 

• 

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 energy 
industry, the automotive production industry and the real estate business. These industries are sensitive to global economic 

14

conditions, supply chain factors and/or commodities prices. Any decline in one of those customers' businesses or industries 
could cause increased credit losses, which in turn could adversely affect Comerica. Further, any decline in these businesses 
or industries could cause decreased borrowings, either due to reduced demand or reductions in the borrowing base available 
for each customer loan. In particular, oil and gas prices have fallen sharply since mid-2014. Loans in the Middle Market 
- Energy business line were $3.6 billion, or approximately 7 percent of total loans, at December 31, 2014.  If oil and gas 
prices remain depressed for a prolonged period of time, Comerica's energy portfolio could decrease and/or experience 
increased credit losses, which could adversely affect Comerica's financial results.

• 

Operational difficulties, failure of technology infrastructure or information security incidents could adversely 
affect Comerica's business and operations.

Comerica is exposed to many types of operational risk, including legal risk, the risk of fraud or theft by employees or 
outsiders, failure of Comerica's controls and procedures and unauthorized transactions by employees or operational errors, 
including clerical or recordkeeping errors or those resulting from computer or telecommunications systems malfunctions. 
Given  the  high  volume  of  transactions  at  Comerica,  certain  errors  may  be  repeated  or  compounded  before  they  are 
identified and resolved. The occurrence of such operational risks can lead to other types of risks including reputational 
and compliance risks that may amplify the adverse impact to Comerica.

In particular, Comerica's operations rely on the secure processing, storage and transmission of confidential and other 
information on its technology systems and networks. 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 may also be subject to disruptions of its operating systems arising from events that are wholly or partially 
beyond its control, which may include, for example, computer viruses, cyber attacks (including cyber attacks resulting 
in the destruction or exfiltration of data and systems), spikes in transaction volume and/or customer activity, electrical 
or  telecommunications  outages,  or  natural  disasters. 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 give rise to interruptions in service to 
customers and loss or liability to Comerica. For example, along with a number of other large financial institutions' websites, 
Comerica’s website, www.comerica.com, was subject to denial of service attacks in 2013. These events did not result in 
a breach of Comerica’s client data, and account information remained secure; however, during one attack, some customers 
may have been prevented from accessing Comerica Bank’s secure websites through www.comerica.com. In all cases, the 
attacks primarily resulted in inconvenience; however, future cyber attacks could be more disruptive and damaging, and 
Comerica may not be able to anticipate or prevent all such attacks. 

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.

Further, Comerica may be impacted by data breaches at retailers and other third parties who participate in data interchanges 
with Comerica customers that involve the theft of customer data, which may include the theft of Comerica debit card 
PIN numbers and commercial cards used to make purchases at such retailers and other third parties. Such data breaches 
could result in Comerica incurring significant expenses to reissue debit cards and cover losses, which could result in a 
material adverse effect on its results of operations. 

• 

Comerica relies on other companies to provide certain key components of its business infrastructure, 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 business infrastructure. Third party vendors provide certain key components of Comerica's 
business infrastructure, such as data processing and storage, payment processing services, recording and monitoring 
transactions, internet connections and network access, clearing agency and card processing services. While Comerica 
conducts due diligence prior to selecting these third party vendors, it does not control their operations. As such, any failure 
on the part of these business partners to perform their various responsibilities could also expose financial institutions to 
risks that can result in reputational problems, financial loss or regulatory actions, and otherwise adversely affect Comerica's 
business and operations. Additionally, federal banking regulators recently issued regulatory guidance on how banks select, 
engage and manage their outside vendors. These regulations may affect the circumstances and conditions under which 
we work with third parties and the cost of managing such relationships. 

15

• 

• 

Noninterest expenses are important to our profitability, but are subject to a number of factors, some of which are 
not in our control.

Many factors can influence the amount of noninterest expenses, including changing regulations, rising pension and health 
care costs, technology and cybersecurity investments and litigation. The importance of managing expenses has been 
amplified in the current slow growth, low net interest margin business environment. Comerica's noninterest expenses 
may increase more than anticipated, which could result in an adverse impact on net income.

Changes in the financial markets, including 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, the trade, fiscal and monetary policies of the federal government and the policies of 
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. Interest rates over the past several years have remained at 
low levels. A continued low interest rate environment could adversely affect the interest income Comerica earns on loans 
and investments. For a discussion of Comerica's interest rate sensitivity, please see, “Market and Liquidity Risk” beginning 
on page F-29 of the Financial Section of this report.

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, because 
of the absence of federal insurance premiums and reserve requirements, generally pay higher rates of return than financial 
institutions. Comerica's financial results could be materially adversely impacted by changes in financial market conditions.

• 

Any reduction in our credit rating 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, including conditions affecting the financial services 
industry generally. There can be no assurance that Comerica will maintain its current ratings. In March 2012, Moody's 
Investors  Service  downgraded  Comerica's  long-term  and  short-term  senior  credit  ratings  one  notch  to A3  and  P-2, 
respectively. From July 2012 through October 2013, Fitch Ratings had Comerica's outlook as “Negative”; in October 
2013, Fitch Ratings affirmed Comerica's rating while revising the outlook to “Stable.” In January 2015, Standard & Poor's 
revised its outlook on Comerica to "Negative" from "Stable." 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.

• 

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, Comerica could experience an increase in the level of provision for credit losses, nonperforming 
assets, net charge-offs and reserve for credit losses, which could adversely affect Comerica's financial results.

• 

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 realized upon or is liquidated 
at prices not sufficient to recover the full amount of the financial instrument exposure due to Comerica. There is no 
assurance that any such losses would not adversely affect, possible materially in nature, Comerica.

16

• 

• 

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 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 efficient and effective utilization of technology enables financial institutions to better 
serve customers and 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 among financial institutions 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 in terms of products and pricing with large 
national and regional financial institutions and with smaller financial institutions. Some of Comerica's larger competitors, 
including certain nationwide banks that have a significant presence in Comerica's market area, may make available to 
their customers a broader array of product, pricing and structure alternatives and, due to their asset size, may more easily 
absorb loans in a larger overall portfolio. Some of Comerica's smaller competitors may have more liberal lending policies 
and processes. 

Additionally, the financial services industry has recently been subject to increasing 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 a significantly different or reduced degree of 
regulation due to their asset size or types of products offered. They may also have the ability to more efficiently utilize 
resources to comply with regulations or may be able to more effectively absorb the costs of regulations into their existing 
cost structure. 

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.

• 

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

Comerica uses a variety of financial tools, models and other methods to anticipate customer behavior as a part of its 
strategic  planning  and  to  meet  certain  regulatory  requirements.  Individual,  economic,  political,  industry-specific 
conditions and other factors outside of Comerica's control, such as fuel prices, energy costs, 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  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.

• 

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 the 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 

17

will 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.

• 

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 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. 

Further, Comerica's ability to retain key officers and employees may be impacted by legislation and regulation affecting 
the financial services industry. On April 14, 2011, FRB, OCC and several other federal financial regulators issued a joint 
proposed  rulemaking  to  implement  Section 956  of  the  Dodd-Frank Act.  Section 956  requires  the  regulators  to  issue 
regulations that prohibit incentive-based compensation arrangements that encourage inappropriate risk taking by covered 
financial institutions and are deemed to be excessive, or that may lead to material losses. Consistent with the Dodd-Frank 
Act, the proposed rule would not apply to institutions with total consolidated assets of less than $1 billion, and 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 that at least 50 percent of incentive-based payments be 
deferred over a minimum period of three years for designated executives. Moreover, boards of directors of these larger 
institutions would be required to identify employees who 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, and to determine that the incentive 
compensation  for  these  employees  appropriately  balances  risk  and  rewards  according  to  enumerated  standards. 
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.

• 

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  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.

• 

Methods of reducing risk exposures might not be effective.

Instruments, systems and strategies used to hedge or otherwise manage exposure to various types of credit, market, 
liquidity, operational, compliance and strategic risks could be less effective than anticipated. As a result, 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.

18

• 

• 

Terrorist activities or other hostilities may adversely affect the general economy, financial and capital markets, 
specific industries, and Comerica.

Terrorist attacks or other hostilities may disrupt Comerica's operations or those of its customers. 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.

Catastrophic events, including, but not limited to, hurricanes, tornadoes, earthquakes, fires, droughts and floods, 
may adversely affect the general economy, financial and capital markets, specific industries, and Comerica.

Comerica has significant operations and a significant customer base in California, Texas, Florida and other regions where 
natural and other disasters may occur. These regions are known for being vulnerable to natural disasters and other risks, 
such as tornadoes, hurricanes, earthquakes, fires, droughts and floods. These types of natural catastrophic events at times 
have  disrupted  the  local  economy,  Comerica's  business  and  customers  and  have  posed  physical  risks  to  Comerica's 
property. In addition, catastrophic events occurring in other regions of the world may have an impact on Comerica's 
customers  and  in  turn,  on  Comerica. A  significant  catastrophic  event  could  materially  adversely  affect  Comerica's 
operating results.

• 

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 policies 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 policies and processes are fundamental to how Comerica records and reports the financial condition and 
results of operations. Management must exercise judgment in selecting and applying many of these accounting policies 
and processes so they comply with U.S. GAAP. In some cases, management must select the 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 policies 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. See “Critical Accounting Policies” on pages F-37 through F-40 of 
the Financial Section of this report and Note 1 of the Notes to Consolidated Financial Statements located on pages F-48 
through F-61 of the Financial Section of this report.

2014 OVERVIEW AND 2015 OUTLOOK

Comerica Incorporated (the Corporation) is a financial holding company headquartered in Dallas, Texas. The Corporation's 
major business segments are the Business Bank, the Retail Bank and Wealth Management. The core businesses are tailored to 
each of the Corporation's three primary geographic markets: Michigan, California and Texas. 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.  
The most critical of these significant accounting policies are discussed in the “Critical Accounting Policies” section of this financial 
review. 

OVERVIEW

•  Net income was $593 million in 2014, an increase of $52 million, or 10 percent, compared to $541 million in 2013. Net 
income per diluted common share was $3.16 in 2014, compared to $2.85 in 2013. Excluding the impact to 2013 results of 
an unfavorable jury verdict in a lender liability case, which decreased 2013 net income by $28 million, or 15 cents per 
share, 2014 net income increased $24 million, or 4 percent, and earnings per diluted share increased 16 cents, or 5 percent. 
•  Average loans were $46.6 billion in 2014, an increase of $2.2 billion, or 5 percent, compared to 2013. The increase in 
average loans primarily reflected an increase of $1.7 billion, or 6 percent, in commercial loans, $158 million, or 10 percent, 
in residential mortgage loans and $117 million, or 5 percent, in consumer loans.  The increase in commercial loans primarily 
reflected increases in Technology and Life Sciences, National Dealer Services, Energy and general Middle Market,  partially 
offset by a decrease in Mortgage Banker Finance.  

•  Average deposits increased $3.1 billion, or 6 percent, to $54.8 billion in 2014, compared to 2013. The increase in average 
deposits reflected increases of $2.6 billion, or 12 percent, in average noninterest-bearing deposits and $1.2 billion, or 5 
percent, in money market and interest-bearing checking deposits, partially offset by a decrease of $602 million, or 11 percent, 
in customer certificates of deposit.  The increase in average deposits reflected increases in almost all lines of business and 
in all geographic markets.

•  Net interest income was $1.7 billion in 2014, a decrease of $17 million, or 1 percent, compared to 2013.  The decrease in 
net interest income resulted primarily from a $15 million decrease in the accretion of the purchase discount on the acquired 
loan portfolio. The benefit from an increase in average earning assets of $2.5 billion and lower funding costs was offset by 
continued pressure on yields from the low-rate environment and loan portfolio dynamics.

•  The provision for credit losses decreased $19 million in 2014, compared to 2013, primarily due to continued improvements 
in credit quality.  Improvements in credit quality included a decline of $367 million in the Corporation's criticized loan list 
from December 31, 2013 to December 31, 2014.  The Corporation's criticized loan list is consistent with loans in the Special 
Mention, Substandard and Doubtful categories defined by regulatory authorities. Additional indicators of improved credit 
quality included a $48 million decrease in net credit-related charge-offs in 2014, compared to 2013. 

•  Noninterest income decreased $14 million or 2 percent, in 2014, compared to 2013, primarily the result of a $19 million 
decrease  in  noncustomer-driven  income  categories,  with  the  largest  decreases  in  deferred  compensation  asset  returns, 
securities trading income and warrant income, partially offset by a $5 million increase in customer-driven fees, largely 
driven by increases in fiduciary income and card fees, partially offset by a decrease in letter of credit fees.

•  Noninterest expenses decreased $96 million, or 6 percent, in 2014, compared to 2013, primarily reflecting decreases of $48 

million in litigation-related expenses and $47 million in pension expense.

•  The quarterly dividend was increased to 19 cents per common share in January 2014 and further increased to 20 cents per 

• 

share in April 2014, increases of 12 percent and 5 percent, respectively. 
Shares repurchased under the share repurchase program totaled 5.2 million shares in 2014. Together with dividends of $0.79 
per share, $392 million, or 66 percent of 2014 net income, was returned to shareholders.

F-4

2015 OUTLOOK

Management expectations for 2015, compared to 2014, assuming a continuation of the current economic and low-rate 

environment, are as follows:

•  Average loan growth consistent with 2014, reflecting typical seasonality in Mortgage Banker Finance and National Dealer 

Services throughout the year and continued focus on pricing and structure discipline.

•  Net interest income relatively stable, assuming no rise in interest rates, reflecting a decrease of about $30 million in 
purchase accounting accretion, to $4 million to $6 million, and the impact of a continuing low rate environment on asset 
yields, offset by earning asset growth.
Provision for credit losses higher, consistent with modest net charge-offs and continued loan growth.

• 
•  Noninterest income relatively stable, reflecting growth in fee income, particularly card fees and fiduciary income, mostly 

offset by regulatory impacts on letter of credit, derivative and warrant income.

•  Noninterest  expenses  higher,  reflecting  increases  in  technology,  regulatory  and  pension  expenses,  as  well  as  typical 
inflationary pressures, with continued focus on driving efficiencies for the long term. Technology and regulatory expenses 
are expected to increase approximately $40 million in total, compared to 2014.
Income tax expense to approximate 33 percent of pretax income.

•

NET INTEREST INCOME

Net interest income is the difference between interest and yield-related fees earned on assets and interest paid on liabilities. 
FTE adjustments are made to the yields on tax-exempt assets in order to present tax-exempt income and fully taxable income on 
a comparable basis. FTE adjustments totaled $4 million in 2014 and $3 million in both 2013 and 2012. Gains and losses related 
to the effective portion of risk management interest rate swaps that qualify as hedges are included with the interest expense of the 
hedged item. Net interest income on a FTE basis comprised 66 percent of total revenues in both 2014 and 2013, and 67 percent 
in 2012. The “Analysis of Net Interest Income-Fully Taxable Equivalent” table of this financial review provides an analysis of net 
interest income for the years ended December 31, 2014, 2013, and 2012. The rate-volume analysis in the table above details the 
components of the change in net interest income on a FTE basis for 2014 compared to 2013 and 2013 compared to 2012.

Net interest income was $1.7 billion in 2014, a decrease of $17 million compared to 2013. The decrease in net interest 
income in 2014, compared to 2013, resulted primarily from a $15 million decrease in the accretion of the purchase discount on 
the acquired loan portfolio. The benefits from a $2.5 billion, or 4 percent, increase in average earning assets and lower funding 
costs were offset by lower loan yields. The increase in average earning assets primarily reflected increases of $2.2 billion in average 
loans and $583 million in average interest-bearing deposits with banks, partially offset by a decrease of $287 million in average 
investment securities.

The net interest margin (FTE) in 2014 decreased 14 basis points to 2.70 percent, from 2.84 percent in 2013, primarily 
from decreased yields on loans and an increase in Federal Reserve Bank (FRB) deposits, partially offset by lower deposit rates. 
The decrease in loan yields reflected the impact of a competitive rate environment, a decrease in accretion on the acquired loan 
portfolio, positive credit quality migration throughout the portfolio, lower LIBOR rates and the impact of a $9 million negative 
residual value adjustment to assets in the leasing portfolio. Accretion of the purchase discount on the acquired loan portfolio 
increased the net interest margin by 6 basis points in 2014, compared to 8 basis points in 2013. Average balances deposited with 

F-7

the FRB were $5.4 billion and $4.8 billion in 2014 and 2013, respectively, and are included in “interest-bearing deposits with 
banks” on the consolidated balance sheets.

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.

PROVISION FOR CREDIT LOSSES

The provision for credit losses was $27 million in 2014, compared to $46 million in 2013. The provision for credit losses 

includes both the provision for loan losses and the provision for credit losses on lending-related commitments. 

The provision for loan losses is recorded to maintain the allowance for loan losses at the level deemed appropriate by the 
Corporation  to  cover  probable  credit  losses  inherent  in  the  portfolio. The  provision  for  loan  losses  was  $22  million  in  2014, 
compared to $42 million in 2013. Credit quality in the loan portfolio continued to improve in 2014, compared to 2013. Improvements 
in credit quality included a decline of $367 million in the Corporation's criticized loan list from December 31, 2013 to December 31, 
2014.  Reflected in the decline in criticized loans was a decrease in nonaccrual loans of $77 million.  The Corporation's criticized 
loan list is consistent with loans in the Special Mention, Substandard and Doubtful categories defined by regulatory authorities.

Net loan charge-offs in 2014 decreased $48 million to $25 million, or 0.05 percent of average total loans, compared to 
$73 million, or 0.16 percent, in 2013. The $48 million decrease in net loan charge-offs in 2014, compared to 2013, reflected 
decreases in almost all business lines, with the largest decreases in Commercial Real Estate and general Middle Market, partially 
offset by an increase in Technology and Life Sciences.

The provision for credit losses on lending-related commitments is recorded to maintain the allowance for credit losses 
on lending-related commitments at the level deemed appropriate by the Corporation to cover probable credit losses inherent in 
lending-related commitments. The provision for credit losses on lending-related commitments was $5 million in 2014, compared 
to $4 million in 2013. Lending-related commitment charge-offs were insignificant in 2014 and 2013.

For further discussion of the allowance for loan losses and the allowance for credit losses on lending-related commitments, 
including the methodology used in the determination of the allowances and an analysis of the changes in the allowances, refer to 
Note 1 to the consolidated financial statements and the "Credit Risk" section of this financial review.

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

$

Noninterest income decreased $14 million to $868 million in 2014, compared to $882 million in 2013, reflecting a $19 
million decrease in noncustomer-driven income categories, partially offset by a $5 million increase in customer-driven fees. An 
analysis of significant year over year changes by individual line item follows.

Fiduciary income increased $9 million, or 6 percent, to $180 million in 2014, compared to $171 million in 2013. Personal 
and institutional trust fees are the two major components of fiduciary income. These fees are based on services provided and assets 
managed. Fluctuations in the market values of the underlying assets managed, which include both equity and fixed income securities, 
impact fiduciary income. The increase in 2014 was primarily due to an increase in personal trust fees, largely driven by an increase 
in the volume of fiduciary services sold in the professional trust alliance business and the favorable impact on fees of market value 
increases.

F-8

Card fees, which consist primarily of interchange fees earned on debit cards and commercial cards, increased $6 million, 
or 8 percent, to $80 million in 2014, compared to $74 million in 2013. The increase in 2014 primarily reflected a volume-driven 
increase in commercial charge card interchange revenue. 

Letter of credit fees decreased $7 million, or 12 percent, to $57 million in 2014, compared to $64 million in 2013. The 

decrease in 2014 was primarily due to regulatory-driven decreases in the volume of letters of credit outstanding.

Foreign exchange income increased $4 million, or 9 percent, to $40 million in 2014, compared to $36 million in 2013. 

The increase in 2014 was primarily due to an increase in customer-driven trading volume throughout the year.

 Other noninterest income decreased $26 million, or 15 percent, to $142 million in 2014, compared to $168 million in 
2013, primarily reflecting decreases in deferred compensation plan asset returns, income recognized from the Corporation's third-
party credit card provider, securities trading income and income from principal investing and warrants. The decrease in deferred 
compensation plan asset returns was offset by a decrease in deferred compensation expense in salaries and benefits expense. The 
decrease in income from the Corporation's third-party credit card provider was primarily the result of a change in the timing of 
the recognition of incentives from annually to quarterly in the third quarter 2013. The following table illustrates certain categories 
included in "other noninterest income" on the consolidated statements of income.

Noninterest expenses decreased $96 million, or 6 percent, to $1.6 billion in 2014, compared to $1.7 billion in 2013. An 

analysis of significant increases and decreases by individual line item is presented below.

Salaries and benefits expense decreased $29 million, or 3 percent, to $980 million in 2014, compared to $1.0 billion in 
2013. The decrease in salaries and benefits expense was primarily due to decreases in pension and deferred compensation  expense, 
partially offset by the impact of merit increases and an increase in technology-related contract labor expense. 

F-9

 
Net occupancy and equipment expense increased $8 million, or 4 percent, to $228 million in 2014, compared to $220 
million in 2013. The increase was primarily the result of lease termination charges of $10 million taken in 2014 related to real 
estate optimization. 

Software expense increased $5 million, or 6 percent, to $95 million in 2014, compared to $90 million in 2013. The increase   

was primarily due to an increase in amortization expense as a result of the completion of technology projects throughout the year.

Litigation-related expenses decreased $48 million to $4 million in 2014, compared to $52 million in 2013, primarily as 
a result of the recognition of a $52 million unfavorable jury verdict on a lender liability case in 2013. For further information about 
legal proceedings, refer to Note 21 to the consolidated financial statements.

The Corporation recognized a gain on debt redemption of $32 million in 2014, on the early redemption of a $150 million 
subordinated note  in  the third  quarter 2014,  primarily from the  recognition of  the unamortized value  of a  related, previously 
terminated interest rate swap.

Other noninterest expenses decreased $6 million, or 4 percent, to $173 million in 2014, from $179 million in 2013. The 
decrease primarily reflected decreases of $5 million in other real estate expense and $5 million in losses on other foreclosed 
property, partially offset by an increase of $9 million in charitable contributions to the Comerica Charitable Foundation in 2014.

INCOME TAXES AND RELATED ITEMS

The provision for income taxes was $277 million in 2014, compared to $245 million in 2013.  The $32 million increase 

in the provision for income taxes in 2014, compared to 2013, was due primarily to an increase in pretax income.

Net deferred tax assets were $130 million at December 31, 2014, compared to $257 million at December 31, 2013. The 
decrease of $127 million resulted primarily from an increase in net unrealized gains on investment securities available-for-sale, a 
2014 contribution to the defined benefit pension plan net of an increase in related unrealized losses, legal reserves, accretion of 
the purchase discount on the acquired loan portfolio and stock-based compensation benefits. Deferred tax assets of $408 million 
were evaluated for realization and it was determined that no valuation allowance was needed at both December 31, 2014 and 
December 31, 2013. This conclusion was based on available evidence of loss carryback capacity and projected future reversals of 
existing taxable temporary differences.

2013 RESULTS OF OPERATIONS COMPARED TO 2012

Net interest income was $1.7 billion in 2013, a decrease of $56 million compared to 2012. The decrease in net interest 
income in 2013 resulted primarily from a decrease in yields and a $22 million decrease in the accretion of the purchase discount 
on the acquired loan portfolio, partially offset by the benefit from a $1.6 billion, or 3 percent, increase in average earning assets 
and lower funding costs.  The increase in average earning assets primarily reflected increases of $1.1 billion in average loans and 
$802 million in average interest-bearing deposits with banks, partially offset by a decrease of $278 million in average investment 
securities available-for-sale. 

The net interest margin (FTE) in 2013 decreased 19 basis points to 2.84 percent, from 3.03 percent in 2012, primarily 
from decreased yields on loans and mortgage-backed investment securities, a decrease in accretion of the purchase discount on 
the acquired loan portfolio and an increase in average balances deposited with the FRB, partially offset by lower deposit rates. 
The decrease in loan yields reflected competitive pricing in the low interest rate environment, a shift in the average loan portfolio 
mix, largely due to volume shifts in business mix, as well as lower LIBOR rates, positive credit quality migration throughout the 
portfolio, an increase in lower-yielding average commercial loans and a decrease in higher-yielding commercial mortgage loans. 
Yields on mortgage-backed investment securities decreased as a result of prepayments on higher-yielding securities and new 
investments in lower-yielding securities impacted by the lower rate environment. Accretion of the purchase discount on the acquired 
loan portfolio increased the net interest margin by 8 basis points in 2013, compared to 12 basis points in 2012. Average balances 
deposited with the FRB of $4.8 billion and $4.0 billion in 2013 and 2012, respectively, are included in “interest-bearing deposits 
with banks” on the consolidated balance sheets. The "Analysis of Net Interest Income  - Fully Taxable Equivalent (FTE)" and 
"Rate/Volume Analysis - FTE" tables under the "Net Interest Income" subheading in this section above provide an analysis of net 
interest income (FTE) for 2013 and 2012 and details the components of the change in net interest income on a FTE basis for 2013 
compared to 2012.

The provision for credit losses, which includes both the provision for loan losses and the provision for credit losses on 
lending-related commitments, was $46 million in 2013, compared to $79 million in 2012. The provision for loan losses was $42 
million in 2013 compared to $73 million in 2012. The $31 million decrease in the provision for loan losses in 2013, when compared 
to 2012, resulted primarily from continued improvements in credit quality, including a decrease of $516 million in the Corporation's 
criticized loan list. Reflected in the decline in criticized loans was a decrease in nonaccrual loans of $169 million. Net loan charge-
offs in 2013 decreased $97 million to $73 million, or 0.16 percent of average total loans, compared to $170 million, or 0.39 percent, 
in 2012.  The $97 million decrease in net loan charge-offs in 2013, compared to 2012, reflected decreases in all geographic markets 

F-10

and across almost all business lines. The provision for credit losses on lending-related commitments was $4 million in 2013, 
compared to $6 million in 2012. The $2 million decrease in the provision for credit losses on lending-related commitments resulted 
primarily from the reduction of specific reserves established in 2012 for set aside/bonded stop loss commitments related to residential 
real estate construction credits in the California market. The reserves for set aside/bonded stop loss commitments were reduced 
in 2013 as the underlying commitments were funded and simultaneously charged-off against the allowance for loan losses. Lending-
related commitment charge-offs were insignificant in 2013 and 2012.

Noninterest income increased $12 million to $882 million in 2013, compared to $870 million in 2012. Fiduciary income 
increased $13 million, or 8 percent in 2013, primarily due to an increase in personal trust fees, largely driven by an increase in the 
volume of fiduciary services sold and the favorable impact on fees of market value increases. Commercial lending fees increased 
$3 million, or 3 percent, primarily due to an increase in fees earned on the unused portion of lines of credit. Card fees increased 
$9 million, or 14 percent in 2013, primarily reflecting volume-driven increases in commercial charge card and debit card interchange 
revenue. Letter of credit fees decreased $7 million, or 10 percent in 2013, primarily due to a decrease in the volume of letters of 
credit outstanding. Net securities gains (losses) decreased $13 million in 2013, primarily reflecting a decrease in gains on the 
redemption of auction-rate securities.  Other noninterest income increased $10 million, or 7 percent, in 2013, compared to 2012. 
The increase primarily reflected increases of $6 million in deferred compensation plan asset returns, $6 million in income from 
principal investing and warrants and $5 million in income from the Corporation's third-party credit card provider, partially offset 
by a $5 million decrease in income from securities trading. The increase in income from the Corporation's third-party credit card 
provider primarily reflected a change in the timing of the recognition of incentives from annually to quarterly in 2013. Refer to 
the table provided under the “Noninterest Income” subheading previously in this section for the details of certain categories included 
in other noninterest income. 

Noninterest expenses decreased $35 million, or 2 percent, in 2013, compared to 2012. Salaries and benefits expense 
decreased $9 million in 2013, primarily reflecting reduced staffing levels and lower executive incentive compensation, partially 
offset by increases in deferred compensation expense and defined benefit pension expense, as well as annual merit increases.  Net 
occupancy expense decreased $8 million, primarily due to savings associated with leased properties exited in 2012, lower utility 
expense and a reduction in equipment depreciation expense, partially offset by an increase in maintenance expense and an increase 
in property tax expense as a result of refunds received in 2012 related to settlements of tax appeals.  Outside processing fee expense 
increased $12 million in 2013, primarily due to increased activity tied to fee-based revenue growth, transactional costs related to 
increased volume and outsourcing of certain operational functions. Litigation-related expenses increased $29 million in 2013, 
primarily reflecting an increase in legal reserves related to an unfavorable jury verdict on a lender liability case. FDIC insurance 
expense decreased $5 million in 2013, primarily the result of lower assessment rates, reflecting improvements in the Corporation's 
risk profile used in determining the quarterly assessment rate.  Advertising expense decreased $6 million in 2013, primarily due 
to timing changes related to certain marketing campaigns. Merger and restructuring charges related to the acquisition of Sterling 
Bancshares, Inc. in 2011 decreased $35 million from 2012 as the integration plan was completed.  Other noninterest expenses 
decreased $12 million in 2013, primarily reflecting decreases of $7 million in other real estate expenses, $6 million in operational 
losses, $7 million in legal fees and $5 million in core deposit intangible amortization, partially offset by an $8 million decrease in 
net gains recognized on sales of assets and a $5 million loss on other foreclosed property in 2013.

The provision for income taxes increased $4 million to $245 million in 2013.  An increase in taxes due to increased pretax 

income in 2013 was largely offset by certain federal and state tax discrete items and the release of certain tax reserves in 2013.

STRATEGIC LINES OF BUSINESS

The Corporation's operations are strategically aligned into three major business segments: the Business Bank, the Retail 
Bank and Wealth Management. These business segments are differentiated based upon the products and services provided. In 
addition to the three major business segments, Finance is also reported as a segment. The Other category includes items not directly 
associated with these 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.  Market  segment  results  are  also  provided  for  the 
Corporation's three primary geographic markets: Michigan, California and Texas. In addition to the three primary geographic 
markets,  Other  Markets  is  also  reported  as  a  market  segment.  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 these business segments for the years ended December 31, 2014, 2013 and 2012.

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.

In the second quarter 2014, the Corporation enhanced the approach used to determine the standard reserve factors used 
in estimating the allowance for credit losses, which had the effect of capturing certain elements in the standard reserve component 
that had formerly been included in the qualitative assessment. The impact of the change was largely neutral to the total allowance 
for loan losses. However, because standard reserves are allocated to the segments at the loan level, while qualitative reserves are 
allocated at the portfolio level, the impact of the methodology change on the allowance of each segment reflected the characteristics 
of the individual loans within each segment's portfolio, causing segment reserves to increase or decrease accordingly. As a result, 
the current year provision for credit losses within each segment is not comparable to prior year amounts.

(a)  Includes items not directly associated with the three major business segments or the Finance Division.

The Business Bank's net income of $816 million in 2014 increased $31 million, compared to $785 million in 2013. Net 
interest income (FTE) of $1.5 billion increased $9 million in 2014, primarily the result of the benefit from an increase in average 
loans of  $1.9 billion, an increase in net funds transfer pricing (FTP) credits and lower deposit costs, partially offset by lower loan 
yields, a decrease in accretion of the purchase discount on the acquired loan portfolio and the impact of a $9 million negative 
residual value adjustment to assets in the leasing portfolio. The increase in net FTP credits primarily reflected the benefit from a 
$2.4 billion increase in average deposits in 2014, compared to 2013. The provision for credit losses decreased $1 million, to $53 
million in 2014, compared to the prior year. Provision decreases in Environmental Services, National Dealer Services and Corporate 
Banking were mostly offset by increases in Mortgage Banker Finance, Energy, and Technology and Life Sciences. Net credit-
related charge-offs of $15 million decreased $28 million in 2014, compared to 2013, primarily reflecting decreases in Commercial 
Real Estate, general Middle Market and Environmental Services, partially offset by an increase in Technology and Life Sciences. 
Noninterest income of $376 million in 2014 decreased $6 million from the prior year, primarily reflecting a $7 million decrease 
in letter of credit fees and small decreases in most other categories of noninterest income, partially offset by a $6 million increase 
in card fees. Noninterest expenses of $590 million in 2014 decreased $53 million compared to the prior year, primarily due to a 
$50 million decrease in litigation-related expenses, a $10 million decrease in salaries and benefits expense and a $7 million decrease 
in expenses related to foreclosed properties, partially offset by a $14 million increase in corporate overhead expense. The increase 
in corporate overhead expense was primarily related to certain actions taken in the third quarter 2014 including a contribution to 
the Comerica Charitable Foundation, charges associated with real estate optimization and several other efficiency-related actions.

Net income for the Retail Bank of $43 million in 2014 increased $1 million, compared to net income of $42 million in 
2013. Net interest income (FTE) of $596 million decreased $14 million in 2014, primarily due to lower loan yields, a decrease in 
accretion of the purchase discount on the acquired loan portfolio and a decrease in net funds transfer pricing (FTP) credits due to 

F-12

 
 
 
 
the lower interest rate environment, partially offset by the benefit provided by a $135 million increase in average loans and lower 
deposit rates. Average deposits increased $463 million. The provision for credit losses was a benefit of $5 million in 2014, compared 
to a provision of $13 million in 2013. Net credit-related charge-offs of $11 million in 2014 decreased $11 million compared to 
2013, reflecting decreases in both Small Business and Retail Banking. Noninterest income of $167 million in 2014 decreased $8 
million compared to 2013, primarily due to a $5 million decrease in income from the Corporation's third-party credit card provider, 
largely reflecting a change in the timing of the recognition of incentives from annually to quarterly in the third quarter 2013. 
Noninterest expenses of $702 million in 2014 decreased $6 million from the prior year, primarily due to a $5 million decrease in 
salaries and benefits expense and small decreases in several other noninterest expense categories, partially offset by a $7 million 
increase in corporate overhead expense, largely for the same reasons as described above in the Business Bank discussion.

Wealth Management's net income of $91 million in 2014 increased $4 million, compared to $87 million in 2013. Net 
interest income (FTE) of $186 million in 2014 increased $2 million compared to 2013, as the benefit provided by a $161 million 
increase in average loans was largely offset by a decline in loan yields. Average deposits increased $259 million. The provision 
for credit losses was a benefit of $20 million in 2014, compared to a benefit of $18 million in 2013. Net credit-related recoveries 
were $1 million in 2014, compared to charge-offs of $8 million in 2013. Noninterest income of $259 million increased $7 million 
from the prior year, primarily reflecting a $10 million increase in fiduciary income, partially offset by small decreases in several 
other categories of noninterest income. Noninterest expenses of $322 million in 2014 increased $3 million from the prior year, 
primarily due to a $5 million increase in corporate overhead expense and a $5 million increase in litigation-related expenses, 
partially offset by a decrease of $8 million in salaries and benefits expense. See the Business Bank discussion for an explanation 
of the increase in corporate overhead expense.

The net loss in the Finance segment was $357 million in 2014, compared to a net loss of $376 million in 2013.  Net 
interest expense (FTE) of $662 million in 2014 increased $9 million, compared to 2013, primarily reflecting an increase in net 
FTP expense as a result of higher deposit levels in the business segments, partially offset by lower net rates paid to the business 
segments under the Corporation's internal FTP methodology. Noninterest income of $60 million in 2014 decreased $1 million 
compared to 2013.  A decrease in noninterest expenses of $31 million in 2014 was primarily the result of the third quarter 2014 
gain of $32 million on the early redemption of debt.

(a)  Includes items not directly associated with the market segments.

The Michigan market's net income of $297 million in 2014 increased $36 million, compared to net income of $261 million 
in 2013. Net interest income (FTE) of $718 million in 2014 decreased $33 million, primarily due to lower loan yields, partially 
due to the impact of a $9 million negative residual value adjustment to assets in the leasing portfolio and the impact of a $125 
million decrease in average loans. Average deposits increased $677 million. The provision for credit losses was a benefit of $32 
million in 2014, a decrease of $20 million compared to a benefit of $12 million in the prior year. Net credit-related charge-offs of 
$8  million  for  2014  increased  $2  million  from  the  prior  year,  primarily  reflecting  increases  in  general  Middle  Market  and 
Commercial Real Estate, partially offset by decreases in most other lines of business. Noninterest income of $360 million in 2014 
increased $3 million from 2013, primarily due to small increases in several noninterest income categories. Noninterest expenses 
of $644 million in 2014 decreased $70 million from the prior year, primarily reflecting a $47 million decrease in litigation-related 
expenses, an $8 million decrease in salaries and benefits expense and small decreases in several noninterest expense categories, 
partially offset by a $7 million increase in corporate overhead expenses. See the Business Bank discussion for an explanation of 
the increase in corporate overhead expense.

The California market's net income of $272 million increased $4 million in 2014, compared to $268 million in 2013.  Net 
interest income (FTE) of $722 million for 2014 increased $30 million from the prior year, primarily due to the benefit provided 

F-13

 
 
by a $1.4 billion increase in average loans and an increase in net FTP credits, partially offset by lower loan yields. Average deposits 
increased $1.4 billion. The provision for credit losses of $28 million in 2014 increased $10 million from the prior year, primarily 
due to an increase in general Middle Market, partially offset by decreases in almost all other business lines. Net credit-related 
charge-offs of $22 million in 2014 decreased $5 million compared to 2013, primarily reflecting decreases in most lines of business, 
partially offset by increases in Technology and Life Sciences and general Middle Market. Noninterest income of $147 million in 
2014 decreased $3 million from the prior year, primarily due to decreases of $3 million each in warrant income and securities 
trading income, partially offset by smaller increases in foreign exchange income, card fees and several other categories of noninterest 
income. Noninterest expenses of $401 million in 2014 increased $5 million from the prior year, primarily reflecting a $7 million 
increase in corporate overhead expenses and small increases in several other noninterest expense categories, partially offset by a 
$6 million decrease in salaries and benefits expense and a $5 million decrease in losses related to foreclosed property. See the 
Business Bank discussion for an explanation of the increase in corporate overhead expense.

The Texas market's net income decreased $17 million to $160 million in 2014, compared to $177 million in 2013. Net 
interest income (FTE) of $542 million in 2014 increased $1 million from the prior year, primarily due to the benefit provided by 
a $965 million increase in average loans and lower deposit rates, partially offset by lower loan yields and a decrease in accretion 
of the purchase discount on the acquired loan portfolio. Average deposits increased $517 million. The provision for credit losses 
of  $50 million in 2014 increased $15 million from the prior year, primarily reflecting increases in Energy, Commercial Real Estate 
and Technology and Life Sciences, partially offset by a decrease in Small Business. Refer to the "Allowance for Credit Losses" 
and "Energy Lending" subheadings in the Risk Management section of this financial review for a discussion of the impact of the 
significant decline in oil and gas prices in the late third and fourth quarters of 2014 on the Corporation's portfolio of energy-related 
loans. Net credit-related charge-offs of $9 million for 2014 decreased $11 million from the prior year, with decreases in almost 
all lines of business. Noninterest income of $129 million in 2014 decreased $3 million from the prior year, primarily due to a 
decrease in syndication fees, a component of commercial lending fees. Noninterest expenses of $369 million in 2014 increased 
$6 million from 2013, primarily due to an $8 million increase in corporate overhead expenses, partially offset by small decreases 
in several other categories of noninterest expenses. See the Business Bank discussion, above, for an explanation of the increase 
in corporate overhead expense.

Net income in Other Markets of $221 million in 2014 increased $13 million compared to $208 million in 2013. Net 
interest income (FTE) of $312 million in 2014 decreased $1 million from the prior year, primarily due to the impact of a decrease 
in average loans of $76 million and lower loan yields, partially offset by an increase in net FTP credits. Average deposits increased 
$476 million. The provision for credit losses decreased $26 million in 2014, compared to the prior year, primarily reflecting 
decreases  in  general  Middle  Market,  Environmental  Services  and  Commercial  Real  Estate,  partially  offset  by  an  increase  in 
Mortgage Banker Finance. Net credit-related recoveries were $14 million in 2014 compared to net charge-offs of $20 million in 
2013, primarily reflecting decreases in general Middle Market, Commercial Real Estate and Environmental Services. Noninterest 
income of $166 million in 2014 decreased $4 million from the prior year, primarily reflecting a $5 million decrease in income 
from the Corporation's third-party credit card provider, largely due to a change in the timing of the recognition of incentives from 
annually to quarterly in the third quarter 2013 and small decreases in several other noninterest income categories, partially offset 
by a $4 million increase in fiduciary income. Noninterest expenses of $200 million in 2014 increased $3 million compared to the 
prior year, primarily due to a $3 million increase in corporate overhead expenses, a $3 million increase in efficiency-related 
occupancy expenses and small increases in several other noninterest expense categories, partially offset by a $7 million decrease 
in salaries and benefits expense. See the Business Banking discussion for an explanation of the increase in corporate overhead 
expense.

The net loss for the Finance & Other category of $357 million in 2014 decreased $16 million  compared to 2013, primarily 
reflecting a $19 million decrease in net loss in the Finance segment, largely due to the third quarter 2014 gain of $32 million on 
the early redemption of debt as previously discussed under the "Business Segments" subheading above.

Average total loans increased $2.2 billion, or 5 percent, to $46.6 billion in 2014, compared to $44.4 billion in 2013, 
primarily  reflecting  increases  of  $1.7  billion,  or  6  percent,  in  commercial  loans,  $423  million,  or  28  percent,  in  real  estate 
construction loans and $158 million, or 10 percent, in residential mortgage loans, partially offset by a decrease of $354 million, 
or 4 percent, in commercial mortgage loans. The $1.7 billion increase in average commercial loans primarily reflected increases 
in Technology and Life Sciences ($505 million), National Dealer Services ($458 million), Energy ($340 million) and general 
Middle Market ($311 million), partially offset by a decrease in Mortgage Banker Finance ($264 million). Middle Market business 
lines generally serve customers with annual revenue between $20 million and $500 million, while Corporate Banking serves 
customers with revenue over $500 million. The decline in Mortgage Banker Finance, which provides mortgage warehousing lines, 
primarily reflected a decline in residential mortgage refinancing activity. Changes in average total loans by geographic market are 
provided in the table above. 

Commercial real estate loans comprise real estate construction loans and commercial mortgage loans.The $69 million 
increase in average commercial real estate loans primarily reflected increased construction loan activity in the Commercial Real 
Estate business line, which primarily includes loans to real estate developers, mostly offset by a decrease in owner-occupied 
commercial mortgages, which largely reflected payments on existing loans  faster than new commitments were originated and

being drawn.  Commercial mortgage loans are loans where the primary collateral is a lien on any real property.  Real property is 
generally considered primary collateral if the value of that collateral represents more than 50 percent of the commitment at loan 
approval.  Average commercial real estate loans to borrowers in the Commercial Real Estate business line represented $3.3 billion, 
or 32 percent of average total commercial real estate loans, in 2014, compared to $3.0 billion, or 28 percent of average total 
commercial real estate loans, in 2013. The remaining $7.3 billion and $7.6 billion of average commercial real estate loans in other 
business lines in 2014 and 2013, respectively, were primarily loans secured by owner-occupied real estate. For more information 
on real estate loans, refer to “Commercial and Residential Real Estate Lending” in the “Risk Management” section of this financial 
review.

Total loans were $48.6 billion at December 31, 2014, an increase of $3.1 billion from December 31, 2013, primarily 
reflecting an increase of $2.7 billion, or 9 percent, in commercial loans. The increase in commercial loans primarily reflected 
increases  in  Energy  ($670  million),  Technology  and  Life  Sciences  ($601  million),  National  Dealer  Services  ($405  million), 
Mortgage Banker Finance ($377 million) and smaller increases in most other lines of business.

Investment Securities

Investment securities increased $744 million to $10.1 billion at December 31, 2014, from $9.3 billion at December 31, 
2013, primarily reflecting purchases out-pacing paydowns on residential mortgage-backed investment securities (RMBS) as well 
as an increase in fair value. Unrealized gains on investment securities were $79 million at December 31, 2014, compared to an 
unrealized  loss  of  $107  million  at  December 31,  2013. At  December 31,  2014,  the  weighted-average  expected  life  of  the 
Corporation's  residential mortgage-backed  securities portfolio  was  approximately  4.0  years.  On  an average  basis,  investment 
securities decreased $287 million to $9.4 billion in 2014, compared to $9.6 billion in 2013. During the fourth quarter 2014, the 
Corporation transferred residential mortgage-backed securities with a fair value of approximately $2.0 billion from available-for-
sale to held-to-maturity. Management changed its intent with respect to these securities and committed to hold them to maturity 
partly in response to the issuance of final liquidity coverage requirements (LCR) by U.S. banking regulators. Further information 
about LCR is provided later in the "Risk Management" section under the "Wholesale Funding" subheading.

The Corporation has been purchasing Government National Mortgage Association (GNMA) RMBS to replace paydowns 
on RMBS issued by government-sponsored enterprises, as GNMA securities receive more favorable treatment under LCR rules. 
The following table provides a summary of the composition of the Corporation's RMBS portfolio.

As of December 31, 2014, the Corporation's auction-rate securities portfolio was carried at an estimated fair value of 
$136 million, compared to $159 million at December 31, 2013. During 2014, auction-rate securities with a par value of $34 million 
were redeemed or sold, resulting in net securities gains of $2 million. As of December 31, 2014, approximately 89 percent of the 
aggregate auction-rate securities par value had been redeemed or sold since acquired in 2008 for a cumulative net gain of $54 
million. 

Short-Term Investments

Short-term investments include federal funds sold, interest-bearing deposits with banks and other short-term investments.  
Federal funds sold offer supplemental earnings opportunities and serve correspondent banks. Interest-bearing deposits with banks 
primarily include deposits with the FRB and also include deposits with banks in developed countries or international banking 
facilities of foreign banks located in the United States. These investments provide a range of maturities of less than one year and 
are mostly used to manage liquidity requirements of the Corporation. Other short-term investments include trading securities and 
loans held-for-sale. Loans held-for-sale typically represent residential mortgage loans originated with management's intention to 
sell. Short-term investments decreased $279 million to $5.1 billion at December 31, 2014, compared to $5.4 billion at December 31, 
2013. On an average basis, short-term investments increased $580 million to $5.6 billion in 2014, compared to $5.0 billion in 
2013. Average interest-bearing deposits with banks increased $583 million to $5.5 billion in 2014, compared to 2013, primarily 
reflecting a $596 million increase in average deposits with the FRB.

Average deposits increased $3.1 billion, or 6 percent, to $54.8 billion in 2014, compared to $51.7 billion in 2013. Average 
deposits increased in almost all business lines from 2013 to 2014, with the largest increases in general Middle Market ($962 
million), Technology and Life Sciences ($769 million), Retail Banking ($383 million), Commercial Real Estate ($369 million) 
and Corporate Banking ($362 million). Average deposits increased in all geographic markets from 2013 to 2014, including  increases 
in California ($1.4 billion), Michigan ($677 million), Texas ($517 million) and Other Markets ($476 million). Average noninterest-
bearing deposits increased $2.6 billion, or 12 percent, to $25.0 billion in 2014, compared to $22.4 billion in 2013. At December 31, 
2014, total deposits were $57.5 billion, an increase of $4.2 billion, or 8 percent, compared to $53.3 billion at December 31, 2013. 
Noninterest-bearing deposits were $27.2 billion at December 31, 2014, an increase of $3.3 billion, or 14 percent, compared to 
$23.9 billion at December 31, 2013. 

Short-term borrowings primarily include federal funds purchased and securities sold under agreements to repurchase. 
Average short-term borrowings decreased $11 million, to $200 million in 2014, compared to $211 million in 2013, primarily 
reflecting a decrease in securities sold under agreements to repurchase. Total short-term borrowings at December 31, 2014 were 
$116 million, a decrease of $137 million compared to $253 million at December 31, 2013.

Average medium- and long-term debt decreased $1.0 billion, or 25 percent, to $3.0 billion in 2014, compared to $4.0 
billion in 2013. The Corporation uses medium- and long-term debt to provide funding to support earning assets.  Total medium- 
and long-term debt at December 31, 2014 decreased $864 million to $2.7 billion, compared to $3.5 billion at December 31, 2013. 
The net decrease resulted from the maturity or redemption of $1.0 billion of FHLB advances and $400 million of subordinated 
notes, partially offset by the issuances of $250 million of subordinated notes and $350 million of medium-term notes.

Further information on medium- and long-term debt is provided in Note 12 to the consolidated financial statements.

The Federal Reserve completed its 2014 Comprehensive Capital Analysis and Review (CCAR) in March 2014 and did 
not object to the Corporation's 2014 capital plan and the capital distributions contemplated in the plan. The plan provides for up 
to $236 million in share repurchases for the four-quarter period ending March 31, 2015. At December 31, 2014, up to $59 million 
remained available for share repurchases under the plan. Share repurchases under the share repurchase program totaled $249 
million (5.2 million shares) in 2014. The 2015 capital plan was submitted to the Federal Reserve for review in January 2015 and 
a response is expected in March 2015.

(c)  The Corporation made no repurchases of warrants under the repurchase program during the year ended December 31, 2014. Upon exercise 
of a warrant, the number of shares with a value equal to the aggregate exercise price is withheld from an exercising warrant holder as 
payment (known as a "net exercise provision"). During the year ended December 31, 2014, the Corporation withheld the equivalent of 
approximately 491,000 shares to cover an aggregate of $25.1 million in exercise price and issued approximately 361,000 shares to the 
exercising warrant holders. Shares withheld in connection with the net exercise provision are not included in the total number of shares or 
warrants purchased in the above table.

(d)  Includes April 22, 2014 share repurchase authorization for up to an additional 2.0 million shares.

In April 2014, the Board of Directors of the Corporation (the Board) authorized the repurchase of up to an additional 2.0 
million shares of Comerica Incorporated outstanding common stock, in addition to the 5.1 million shares remaining at March 31, 
2014 under the Board's prior authorizations for the share repurchase program initially approved in November 2010. Including the 
April 2014 authorization, a total of 30.3 million shares has been authorized for repurchase under the share repurchase program 
since its inception. In November 2010, the Board authorized the purchase of up to all 11.5 million of the Corporation's original 
outstanding warrants. There is no expiration date for the Corporation's share repurchase program.

F-19

 
In January 2014, the Board approved a 12 percent increase in the quarterly cash dividend, to 19 cents per common share, 
effective with the April 2014 dividend payment, and in April 2014 approved an additional 5 percent increase, to 20 cents per 
common share. The 2014 dividend increases were contemplated in the Corporation's 2014 capital plan. The Corporation declared 
common  dividends  in  2014  totaling  $143  million,  or  $0.79  per  share,  on  net  income  of  $593  million,  compared  to  common 
dividends totaling $0.68 per share in 2013. The dividend payout ratio, calculated on a per share basis, was 24 percent in 2014, 
compared to 23 percent in 2013. Including share repurchases, the total payout to shareholders was 66 percent in 2014, compared 
to 76 percent in 2013.

The Corporation assesses capital adequacy against the risk inherent in the balance sheet, recognizing that unexpected 
loss is the common denominator of risk and that common equity has the greatest capacity to absorb unexpected loss. At December 31, 
2014, 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 and capital ratio 
calculations. The  Corporation  periodically  conducts  stress  tests  to  evaluate  potential  impacts  to  the  Corporation's  forecasted 
financial  condition  under  various  economic  scenarios.  These  stress  tests  are  a  regular  part  of  the  Corporation's  overall  risk 
management and capital planning process. The same forecasting process is also used by the Corporation to conduct the stress test 
that was part of CCAR. For additional information about risk management processes, refer to the "Risk Management" section of 
this financial review.

In July 2013, U.S. banking regulators issued a final rule for the U.S. adoption of the Basel III regulatory capital framework. 
The regulatory framework includes a more conservative definition of capital, two new capital buffers - a conservation buffer and 
a countercyclical buffer, new and more stringent risk weight categories for assets and off-balance sheet items, and a supplemental 
leverage ratio. As a banking organization subject to the standardized approach, the rules are effective for the Corporation on January 
1, 2015, with certain transition provisions fully phased in on January 1, 2018.

According to the rule, the Corporation will be subject to the capital conservation buffer of 2.5 percent, when fully phased 
in, to avoid restrictions on capital distributions and discretionary bonuses. However, the rules do not subject the Corporation to 
the  capital  countercyclical  buffer  of  up  to  2.5  percent  or  the  supplemental  leverage  ratio.  The  Corporation  estimates  the 
December 31, 2014 Tier 1 and common equity Tier 1 risk-based ratio would be 10.3 percent if calculated under the final rule, as 
fully phased in, excluding most elements of accumulated other comprehensive income from regulatory capital. The Corporation's 
December 31, 2014 estimated common equity Tier 1 and Tier 1 capital ratios exceed the minimum required by the final rule (7 
percent and 8.5 percent, respectively, including the fully phased-in capital conservation buffer). For a reconcilement of these non-
GAAP financial measures, refer to the "Supplemental Financial Data" section of this financial review.

On December 9, 2014, U.S. banking regulators proposed a rule that would establish an additional capital buffer for 
banking  organizations  deemed  systemically  important  to  the  global  financial  system  (Globally  Systemically  Important  Bank 
Holding Companies, or “G-SIB”). The Corporation would not be considered a G-SIB under the rule as proposed.

RISK MANAGEMENT

As a result of conducting business in the normal course, the Corporation assumes various types of risk. The Corporation's 
enterprise risk 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 Corporation's 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 are responsible for the day to day management of risks including the identification, 
assessment, measurement and control of risks encountered as a part of the normal course of business.  Risks are further monitored, 
measured  and  controlled  by  specialized  risk  managers  for  each  of  the  major  risk  categories,  who  aid  in  the  identification, 
measurement, and control of organizational risks.  The majority of these risk managers report into the Office of Enterprise Risk.  
The Office of Enterprise Risk, led by the Chief Risk Officer, is responsible for designing and managing the Corporation’s enterprise 
risk 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  monitors  and  assesses  the  overall  effectiveness  of  the  risk 
management framework on an ongoing basis and provides an independent assessment of the Corporation’s ability to manage and 
control risk to management and the Audit Committee of the Board. 

The  Enterprise-Wide  Risk  Management  Committee,  established  by  the  Enterprise  Risk  Committee  of  the  Board,  is 
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. The Enterprise-Wide Risk Management 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, procedures 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, 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. 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, periodically reviewing and approving its credit exposures using approved 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.

Credit Administration 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 business segment reporting 
support as necessary. 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.

Portfolio Risk Analytics, of the Office of Enterprise Risk, 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 

F-21

 
 
 
 
 
 
and the allowance for credit losses on lending-related commitments, calculation of economic credit risk capital and management 
of credit policy to ensure it remains current, relevant and provides comprehensive coverage of credit risk.

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 loan losses represents management's assessment of probable, estimable losses inherent 
in the Corporation's loan portfolio. The allowance for credit losses on lending-related commitments, included in "accrued expenses 
and other liabilities" on the consolidated balance sheets, provides for probable losses inherent in lending-related commitments, 
including unused commitments to extend credit and standby letters of credit. 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.

The initial estimate of fourth quarter 2014 real annualized Gross Domestic Product (GDP) growth of 2.6 percent showed 
that growth in the U.S. economy eased at the end of the year, largely reflecting lower government spending and fixed business 
investments, after strong second and third quarters. Real annualized GDP growth in the second and third quarters of 2014 exceeded 
4.5 percent, and job growth at year-end brought the U.S. unemployment rate down to 5.6 percent in December. Many U.S. metrics, 
including the unemployment rate, are returning to healthier levels. Both consumer and business confidence measures finished the 
year at levels not seen since before the Great Recession, and auto sales trended up to finish the year on par with recent cyclical 
highs. In contrast to the improving trends in U.S. economic indicators through 2014, many global indicators softened. The eurozone 
economy slumped in the second half of 2014, as did Japan's. Global uncertainty, coinciding with stimulatory monetary policy by 
the European Central Bank and the bank of Japan, kept downward pressure on U.S. interest rates, even as the U.S. Federal Reserve 
ended its bond buying program. Falling oil and gas prices through the second half of 2014 added to financial market uncertainty. 
The Corporation believes it has reached near cycle-low levels of criticized loans and loan charge-offs. This is balanced by continued 
loan growth at the Corporation and industry wide.  While overall credit quality of the loan portfolio remained strong through the 
end of 2014, economic complexity and uncertainty continued to be a consideration when determining the appropriateness of the 
allowance for loan losses.

An analysis of the coverage of the allowance for loan losses is provided in the following table.

The allowance for loan losses was $594 million at December 31, 2014, compared to $598 million at December 31, 2013, 
a decrease of $4 million, or 1 percent resulting primarily from an increase in credit quality in the loan portfolio, partially offset 
by higher loan balances. The $4 million decrease in the allowance for loan losses primarily reflected decreased reserves in Corporate 
Banking, Private Banking, and Small Business, partially offset by increased reserves in Energy and Technology and Life Sciences. 
By market, reserves decreased in Michigan and Other Markets and increased in Texas (primarily due to Energy) and California.

Oil and gas prices declined significantly in the late third and fourth quarters of 2014. While no adverse trends had been 
noted in the internal risk ratings of borrowers in the Energy portfolio at December 31, 2014, some borrowers could be adversely 
impacted from this event, resulting in incurred losses that have yet to emerge in the portfolio.  Accordingly, in addition to the 
reserves resulting from the application of standard reserve factors to the portfolio of energy-related loans at December 31, 2014, 
the Corporation included a qualitative adjustment to the allowance for credit losses. In developing the qualitative adjustment, 
management considered a range of possible outcomes for probability of default, loss given default and the loss emergence period, 
as well as historical migration and loss experience under similar economic conditions. The additional reserve on Middle Market- 
Energy loans resulting from the qualitative adjustment was approximately 60 basis points of outstanding Middle Market - Energy 
loan balances at December 31, 2014. Refer to the "Energy Lending" subheading later in this section for further discussion of the 
Corporation's portfolio of energy-related loans.

Acquired loans were initially recorded at fair value, which included an estimate of credit losses expected to be realized 
over the remaining lives of the loans, and therefore no corresponding allowance for loan losses was recorded for these loans at 
acquisition. Methods utilized to estimate the required allowance for loan losses for acquired loans not deemed credit-impaired at 
acquisition are similar to originated loans; however, the estimate of loss is based on the unpaid principal balance less the remaining 
purchase discount, either on an individually evaluated basis or based on the pool of acquired loans not deemed credit-impaired at 
acquisition within each risk rating, as applicable. At December 31, 2014, there was a $1 million allowance for loan losses on 
acquired loans not deemed credit-impaired and $12 million of purchase discount remained, compared to no allowance for loan 
losses and $21 million of remaining purchase discount at December 31, 2013.

The  allowance  for  credit  losses  on  lending-related  commitments  includes  specific  allowances,  based  on  individual 
evaluations of certain letters of credit in a manner consistent with business loans, and allowances based on the pool of the remaining 
letters of credit and all unused commitments to extend credit within each internal risk rating.

The allowance for credit losses on lending-related commitments was $41 million at December 31, 2014 compared to $36 
million at December 31, 2013. The $5 million increase in the allowance for credit losses on lending-related commitments reflected 
increases in both the reserves for unused commitments to extend credit and reserves for standby letters of credit. An analysis of

Nonperforming Assets

Nonperforming assets include loans on nonaccrual status, troubled debt restructured loans (TDRs) which have been 
renegotiated to less than the original contractual rates (reduced-rate loans) and foreclosed property. TDRs include performing and 
nonperforming loans. Nonperforming TDRs are either on nonaccrual or reduced-rate status. Nonperforming assets do not include 
purchased credit impaired (PCI) loans.

Nonperforming assets decreased $83 million to $300 million at December 31, 2014, from $383 million at December 31, 
2013. The decrease in nonperforming assets primarily reflected decreases in nonaccrual commercial mortgage loans ($61 million), 
real estate construction loans ($19 million) and residential mortgage loans ($17 million), partially offset by an increase in nonaccrual 
commercial loans ($28 million).  Nonperforming assets as a percentage of total loans and foreclosed property was 0.62 percent 
at December 31, 2014, compared to 0.84 percent at December 31, 2013.

Concentration 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 

F-26

economic or other conditions.  The Corporation has a concentration of credit risk with the automotive industry. All other industry 
concentrations, as defined by management, individually represented less than 10 percent of total loans at December 31, 2014.

Substantially all dealer loans are in the National Dealer Services business line. Loans in the National Dealer Services 
business  line  primarily  include  floor  plan  financing  and  other  loans  to  automotive  dealerships.  Floor  plan  loans,  included  in 
“commercial loans” in the consolidated balance sheets, totaled $3.8 billion at December 31, 2014, an increase of $286 million 
compared to $3.5 billion at December 31, 2013. At December 31, 2014 other loans in the National Dealer Services business line 
totaled $2.6 billion, including $1.5 billion of owner-occupied commercial real estate mortgage loans, compared to $2.4 billion, 
including $1.4 billion of owner-occupied commercial real estate mortgage loans, at December 31, 2013. Automotive lending also 
includes  loans  to  borrowers  involved  with  automotive  production,  primarily Tier  1  and Tier  2  suppliers.  Loans  to  borrowers 
involved with automotive production totaled approximately $1.2 billion at both December 31, 2014 and 2013.

December 31, 2014, dealer loans, as shown in the table above, totaled $6.4 billion, of which approximately $4.1 billion, 
or 63 percent, were to foreign franchises, and $1.7 billion, or 27 percent, were to domestic franchises. Other dealer loans, totaling 
$646 million, or 10 percent, at December 31, 2014, include obligations where a primary franchise was indeterminable, such as 
loans to large public dealership consolidators and rental car, leasing, heavy truck and recreation vehicle companies.

Nonaccrual loans to automotive borrowers totaled $4 million, or 1 percent of total nonaccrual loans at December 31, 
2014, compared to $5 million, or 1 percent of total nonaccrual loans at December 31, 2013. Total automotive net loan charge-offs 
were $1 million in both 2014 and 2013.

The Corporation limits risk inherent in its commercial real estate lending activities by limiting exposure to those borrowers 
directly involved in the commercial real estate markets, diversifying credit risk by geography and project type, 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 $10.6 billion at December 31, 2014, of which $3.4 billion, or 32 percent, were to borrowers 
in the Commercial Real Estate business line, which includes loans to real estate developers. The remaining $7.2 billion, or 68 

F-27

 
percent,  of  commercial  real  estate  loans  is  to  borrowers  in  other  business  lines  and  consisted  primarily  of  owner-occupied 
commercial mortgages which bear credit characteristics similar to non-commercial real estate business loans. 

The  real  estate  construction  loan  portfolio  primarily  contains  loans  made  to  long-time  customers  with  satisfactory 
completion experience. Real estate construction loans in the Commercial Real Estate business line totaled $1.6 billion with $1 
million on nonaccrual status at December 31, 2014, compared to $1.4 billion with $20 million on nonaccrual status at December 31, 
2013. Net real estate construction loan recoveries in the Commercial Real Estate business line were $4 million in both 2014 and 
2013.

Loans in the commercial mortgage portfolio generally mature within three to five years. Of the $1.8 billion of commercial 
mortgage loans in the Commercial Real Estate business line, $22 million were on nonaccrual status at December 31, 2014, compared 
to $1.7 billion with $51 million on nonaccrual status at December 31, 2013. Commercial mortgage loan net recoveries in the 
Commercial Real Estate business line were $8 million in 2014, compared to net charge-offs of $6 million in 2013. In other business 
lines, $73 million and $105 million of commercial mortgage loans were on nonaccrual status at December 31, 2014 and 2013, 
respectively, and net charge-offs were $2 million and $10 million in 2014 and 2013, respectively.

Residential real estate loans, which consist of traditional residential mortgages and home equity loans and lines of credit, 
totaled $3.5 billion at December 31, 2014. Residential mortgages totaled $1.8 billion at December 31, 2014, and were primarily 
larger, variable-rate mortgages originated and retained for certain private banking relationship customers. Of the $1.8 billion of 
residential mortgage loans outstanding, $36 million were on nonaccrual status at December 31, 2014. The home equity portfolio 
totaled $1.7 billion at December 31, 2014, of which $1.5 billion was outstanding under primarily variable-rate, interest-only home 
equity lines of credit, $120 million were in amortizing status and $76 million were closed-end home equity loans. Of the $1.7 
billion of home equity loans outstanding, $30 million were on nonaccrual status at December 31, 2014. A majority of the home 
equity portfolio was secured by junior liens at December 31, 2014. 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.  

Energy Lending

The  Corporation  has  a  portfolio  of  energy-related  loans  that  are  included  primarily  in  "commercial  loans"  in  the 
consolidated balance sheets. The Corporation has over 30 years of experience in energy lending, with a focus on middle market 
companies. Loans in the Middle Market - Energy business line (approximately 200 borrowers at December 31, 2014) were $3.6 
billion, or approximately 7 percent of total loans, at December 31, 2014, compared to $2.8 billion, or approximately 6 percent of 
total loans, at December 31, 2013. There were no nonaccrual Middle Market - Energy loans at December 31, 2014 and no net 
charge-offs in 2014, compared to $1 million of nonaccrual loans at December 31, 2013 and net charge-offs of $2 million in 2013.  

Credit policy for energy loans includes parameters for collateral, engineering review, advance rates on proven reserves, 
well and field diversity, and environmental due diligence, among other factors. The portfolio of energy-related loans is diverse in 
nature, with outstanding balances by customer market segment distributed approximately as follows at December 31, 2014: 71 
percent exploration and production (EP) (comprising approximately 59 percent oil, 26 percent mixed and 15 percent natural gas), 
16 percent energy services and 13 percent midstream. EP generally includes such activities as searching for potential oil and gas 
fields, drilling exploratory wells and operating active wells. The midstream sector is generally involved in the transportation, 
storage and marketing of crude and/or refined energy products.  Energy services companies provide services to the EP and midstream 
sectors. As of December 31, 2014, a majority of the Corporation’s EP customers had at least 50 percent of their oil and/or gas 
production hedged up to the end of 2015.  Approximately 95 percent of the amount of  loans outstanding in the Middle Market - 
Energy business line had varying levels and types of collateral at December 31, 2014, including oil and gas reserves and pipelines, 
equipment, accounts receivable, inventory and other assets, or some combination thereof. Commitments to EP borrowers are 
F-28

generally subject to borrowing base re-determinations about every six months, based on updated prices which consider the then-
current energy prices and other factors. While no adverse trends had been noted in the internal risk ratings of energy borrowers 
at December 31, 2014 from the significant decline in oil and gas prices in the late third and fourth quarters of 2014, energy borrowers 
could be adversely impacted from this event. Upcoming re-determinations could result in some reductions to the lines of credit 
available to those borrowers, and may result in some internal risk rating downgrades.

Refer to the “Allowance for Credit Losses” subheading earlier in this section for a discussion of changes in the allowance 

for loan losses as a result of the above-described events.

International Exposure

International assets are subject to general risks inherent in the conduct of business in foreign countries, including economic 
uncertainties and each foreign government's regulations. Risk management practices minimize the risk inherent in international 
lending arrangements. These practices include structuring bilateral agreements or participating in bank facilities, which secure 
repayment from sources external to the borrower's country. Accordingly, such international outstandings are excluded from the 
cross-border risk of that country.

Mexico, with cross-border outstandings of $670 million (0.97 percent of total assets), $645 million (0.99 percent of total 
assets) and $569 million (0.87 percent of total assets) at December 31, 2014, 2013 and 2012, respectively, was the only country 
with outstandings between 0.75 and 1.00 percent of total assets at year-end 2014, 2013 and 2012.  There were no countries with 
cross-border outstandings exceeding 1.00 percent of total assets at year-end 2014, 2013 and 2012.

The Corporation does not hold any sovereign exposure to Europe. The Corporation's international strategy as it pertains 
to Europe is to focus on European companies doing business in North America, with an emphasis on the Corporation's primary 
geographic markets.

Market risk represents the risk of loss due to adverse movements in market rates or prices, including interest rates, foreign 
exchange rates, commodity prices and equity prices. Liquidity risk represents the failure to meet financial obligations coming due 
resulting from an inability to liquidate assets or obtain adequate funding, and the inability to easily unwind or offset specific 
exposures without significant changes in pricing, due to inadequate market depth or market disruptions.

The Asset and Liability Policy 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. The Treasury Department  
mitigates market and liquidity risk through the actions it takes to manage the Corporation's market, liquidity and capital positions 
under the direction of ALCO.

Market Risk Analytics, of the Office of Enterprise Risk, supports ALCO in measuring, monitoring and managing interest 
rate and liquidity risks and coordinating all other market risks. Key activities encompass: (i) providing information and analysis 
of the Corporation's balance sheet structure and measurement of interest rate, liquidity 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 

F-29

analysis and strategies to adjust risk positions; (iv) reviewing and presenting policies and authorizations for approval; (v) monitoring 
of industry trends and analytical tools to be used in the management of interest rate, liquidity and all other market risks; and (vi) 
developing and monitoring the interest rate risk economic capital estimate.

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 liability, 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 a combination of core deposits and wholesale borrowings. Approximately 85 percent of the 
Corporation's loans were floating at December 31, 2014, of which approximately 75 percent were based on LIBOR and 25 percent 
were based on Prime. This creates sensitivity to interest rate movements due to the imbalance between the floating-rate loan 
portfolio and the more slowly repricing 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 investment securities, primarily fixed-rate, which provide liquidity to the balance sheet and act to mitigate 
the inherent interest sensitivity, and hedging the sensitivity with interest rate swaps. 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.

Interest Rate Sensitivity

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.

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 and what is believed to be the most likely balance sheet structure. Existing derivative instruments entered 
into for risk management purposes are included in the analysis, but no additional hedging is currently forecasted. These derivative 
instruments currently comprise interest rate swaps that convert fixed-rate long term debt to variable rates. This base case net 
interest income is then compared against interest rate scenarios in which rates rise or decline in a linear, non-parallel fashion from 
the base case over 12 months. In the scenarios presented, short-term interest rates increase 200 basis points, resulting in an average 
increase in short-term interest rates of 100 basis points over the period (+200 scenario). Due to the current low level of interest 
rates, the analysis reflects a declining interest rate scenario of a 25 basis point drop in short-term interest rates, to zero percent.  

F-30

Each scenario includes assumptions such as loan growth, investment security prepayment levels, depositor behavior, 
yield curve changes, loan and deposit pricing, and overall balance sheet mix and growth.  In the +200 scenario, assumptions related 
to loan growth and deposit run-off are based on historical experience, resulting in a modest increase in loans and a modest decrease 
in deposits from the base case.  No changes are modeled to investment securities beyond the replacement of prepayments, and 
expected funding maturities are included.  As a result of the modeled balance sheet movement, excess reserves diminish. In addition, 
the model reflects deposit pricing based on historical price movements with short-term interest rates and loan spread held at current 
levels. The analysis also does not capture possible regulatory impacts, including impacts of the recently finalized liquidity coverage 
ratio (LCR) requirements, which could impact balance sheet structure, product offerings and pricing as well as how interest rate 
risk is managed.  How the Corporation chooses to make additional investments in high-quality, liquid assets (HQLA) and fund 
such investments may have an impact on sensitivity.  Changes in economic activity may result in a balance sheet structure that is 
different from the changes management included in its simulation analysis and may translate into a materially different interest 
rate environment than those presented.  For example, deposit balances have grown significantly over the past several years, creating 
uncertainty regarding future deposit balance levels.  In isolation, a decline in deposit balances beyond historical experience would 
reduce the estimated increase in net interest income in the +200 scenario.

The table below, as of December 31, 2014 and 2013, 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.

Sensitivity increased slightly from December 31, 2013 to December 31, 2014, primarily due to changes in the current 
balance sheet mix driving a revised forecast.  The risk to declining interest rates is limited as a result of the inability of the current 
low level of rates to fall significantly. 

The table below, as of December 31, 2014, illustrates the estimated sensitivity of the above results to a change in deposit 
balance assumptions in the +200 scenario, with all other assumptions held constant. In this analysis, average noninterest-bearing 
deposit run-off in the 12-month period has been increased by $1 billion and $3 billion from the historical run-off experience 
included in the standard +200 scenario presented above and assumes the deposit run-off reduces excess reserves and increases 
purchased funds. The analysis is provided as an indicator of the sensitivity of net interest income to the modeled deposit run-off 
assumption. It is not meant to reflect management's expectation or best estimate. Actual changes in deposit balances may vary

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 economic value of equity analysis is based on an immediate parallel 200 basis point increase and 25 basis point decrease in 
interest rates.

The change in the sensitivity of the economic value of equity to a 200 basis point parallel increase in rates between 
December 31, 2013 and December 31, 2014 was primarily driven by growth in deposits without a stated maturity and by changes 
in market interest rates at the middle to long end of the curve, which most significantly impact the value of deposits without a 
stated maturity.

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 mainly involves interest 
rate swaps effectively converting fixed-rate medium- and long-term debt to floating rate.

unrealized gain of $175 million at December 31, 2014, compared to a net unrealized gain of $290 million at December 31, 2013. 
Risk management interest rate swaps generated $72 million of net interest income for each of the years ended December 31, 2014 
and 2013.

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  forward  contracts  and  foreign 
exchange swap agreements. The aggregate notional amounts of these risk management derivative instruments at December 31, 
2014 and 2013 were $508 million and $253 million, respectively. 

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

statements.

The Corporation writes 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 89 percent and 92 percent of total interest rate, energy and 
foreign exchange contracts at December 31, 2014 and 2013, respectively. 

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

financial statements.

Liquidity Risk and Off-Balance Sheet Arrangements

Liquidity is the ability to meet financial obligations through the maturity or sale of existing assets or the acquisition of 
additional funds. Various financial obligations, including contractual obligations and commercial commitments, may require future 
cash  payments  by  the  Corporation. The  following  contractual  obligations  table  summarizes  the  Corporation's  noncancelable 
contractual obligations and future required minimum payments. Refer to Notes 6, 9, 10, 11, 12, and 18 to the consolidated financial 
statements for further information regarding these contractual obligations.

Since many of these commitments expire without being drawn upon, the total amount of these commercial commitments 
does not necessarily represent the future cash requirements of the Corporation. Refer to the “Other Market Risks” section below 
and Note 8 to the consolidated financial statements for a further discussion of these commercial commitments.

Wholesale Funding

The Corporation may access the purchased funds market when necessary, which includes foreign office time deposits 
and short-term borrowings. Capacity for incremental purchased funds at December 31, 2014 included the ability to purchase 
federal funds, sell securities under agreements to repurchase, as well as issue deposits to institutional investors and issue certificates 
of deposit through brokers. Purchased funds totaled $251 million at December 31, 2014, compared to $602 million at December 31, 
2013.  At December 31, 2014, the Bank had pledged loans totaling $25 billion which provided for up to $19 billion of available 
collateralized borrowing with the FRB.

The Bank is a member of the Federal Home Loan Bank of Dallas, Texas (FHLB), which provides short- and long-term 
funding to its members through advances collateralized by real estate-related assets. Actual borrowing capacity is contingent on 
the amount of collateral available to be pledged to the FHLB. At December 31, 2014, $14 billion of real estate-related loans were 
pledged to the FHLB as blanket collateral to provide capacity for potential future borrowings of approximately $6 billion. As of 
December 31, 2014, the Corporation did not have any outstanding borrowings from the FHLB. 

Additionally, the Bank had the ability to issue up to $15.0 billion of debt at December 31, 2014 under an existing $15 
billion medium-term senior note program which allows the issuance of debt with maturities between three months and 30 years. 
The Corporation also maintains a shelf registration statement with the Securities and Exchange Commission from which it may 
issue debt and/or equity securities.

The ability of the Corporation and the Bank to raise funds at competitive rates is impacted by rating agencies' views of 
the credit quality, liquidity, capital and earnings of the Corporation and the Bank. As of December 31, 2014, the four major rating 
agencies had assigned the following ratings to long-term senior unsecured obligations of the Corporation and 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.

The Corporation satisfies liquidity requirements with either liquid assets or various funding sources. Liquid assets, which 
totaled $13.3 billion at December 31, 2014, compared to $12.6 billion at December 31, 2013, provide a reservoir of liquidity.  
Liquid assets include cash and due from banks, federal funds sold, interest-bearing deposits with banks, other short-term investments 
and unencumbered investment securities. 

In September 2014, U.S. banking regulators issued a final rule implementing a quantitative liquidity requirement in the 
U.S. generally consistent with the LCR minimum liquidity measure established under the Basel III liquidity framework. Under 
the rule, the Corporation is subject to a modified LCR standard, which requires a financial institution to hold a minimum level of 
HQLA to fully cover modified net cash outflows under a 30-day systematic liquidity stress scenario. The rule is effective for the 
Corporation on January 1, 2016. During the transition year, 2016, the Corporation will be required to maintain a minimum LCR 
of  90  percent.  Beginning  January  1,  2017,  and  thereafter,  the  minimum  required  LCR  will  be  100  percent. The  Corporation 
continues to evaluate the impact of the rule; however, we expect to meet the final requirements adopted by U.S. banking regulators 
within the required timetable. To reach full compliance and provide a buffer for normal volatility in balance sheet dynamics, the 

F-34

Corporation expects to add additional HQLA, which may be funded with additional debt, in the future. The Corporation does not 
currently expect compliance with the LCR rule will have a significant impact on net interest income.

The Basel III liquidity framework includes a second minimum liquidity measure, the Net Stable Funding Ratio (NSFR), 
which requires the amount of available longer-term, stable sources of funding to be at least 100 percent of the required amount of 
longer-term stable funding over a one-year period. The Basel Committee on Banking Supervision is in the process of reviewing 
the proposed NSFR standard and evaluating its impact on the banking system. U.S. banking regulators have announced that they 
expect to issue proposed rulemaking to implement the NSFR in advance of its scheduled global implementation in 2018. While 
uncertainty exists in the final form and timing of the U.S. rule implementing the NSFR and whether or not the Corporation will 
be subject to the full requirements, the Corporation is closely monitoring the development of the rule.

The  Corporation  regularly  evaluates  its  ability  to  meet  funding  needs  in  unanticipated,  stressed  environments.  In 
conjunction with the quarterly 200 basis point interest rate simulation analyses, discussed in the “Interest Rate Sensitivity” section 
of this financial review, liquidity ratios and potential funding availability are examined. Each quarter, the Corporation also evaluates 
its ability to meet liquidity needs under a series of broad events, distinguished in terms of duration and severity. The evaluation 
as of December 31, 2014 projected that sufficient sources of liquidity were available under each series of events.

Variable Interest Entities

The Corporation holds interests in certain unconsolidated variable interest entities (VIEs). These unconsolidated VIEs 
are  principally  funds  (limited  partnerships  or  limited  liability  companies)  which  invest  in  low  income  housing  projects. The 
Corporation is not deemed the primary beneficiary of these VIEs and, accordingly, the Corporation does not consolidate these 
VIEs. Refer to the “Principles of Consolidation” section in Note 1 to the consolidated financial statements for a summary of the 
Corporation's consolidation policy as it relates to VIEs.  Also, refer to Note 9 to the consolidated financial statements for a discussion 
of the Corporation's involvement in VIEs, including those in which the Corporation holds a significant interest but for which it is 
not the primary beneficiary.

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, people and systems, or 
from external events. The definition includes legal risk, which is the risk of loss resulting from failure to comply with laws and 
regulations as well as prudent ethical standards and contractual obligations. 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 
management  function  and  business/support  unit  risk  coordinators  responsible  for  managing  operational  risk  specific  to  the 
respective business lines.

COMPLIANCE RISK

Compliance risk represents the risk of regulatory sanctions or financial loss resulting from the Corporation's failure to 
comply with 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 activities regulated by the Dodd-Frank Wall Street Reform and Consumer Protection Act.

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.

F-35

STRATEGIC RISK

Strategic risk represents the risk of loss 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, operational or 
compliance risks. Mitigation of the various risk elements that represent strategic risk is achieved through various metrics and 
initiatives to help the Corporation better understand, measure and report on such risks.

F-36

CRITICAL ACCOUNTING POLICIES

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, 2014, the most critical of these 
significant accounting policies were the policies related to the allowance for credit losses, valuation methodologies, goodwill, 
pension plan accounting and income taxes. These policies were reviewed with the Audit Committee of the Corporation’s Board 
of Directors and are discussed more fully below.

ALLOWANCE FOR CREDIT LOSSES

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 sufficient to absorb estimated probable 
losses. Management's determination of the appropriateness of the allowance is based on periodic evaluations of the loan portfolio, 
lending-related commitments, and other relevant factors. This evaluation is inherently subjective as it requires numerous estimates, 
including the loss content for internal risk ratings, collateral values, the amounts and timing of expected future cash flows, and 
for lending-related commitments, estimates of the probability of draw on unused commitments. 

In determining the allowance for credit losses, the Corporation individually evaluates certain impaired loans, applies 
standard reserve factors to pools of homogeneous loans and lending-related commitments and incorporates qualitative adjustments.  
Standard loss factors, applied to the majority of the Corporation's loan portfolio and lending-related commitments, are based on 
estimates of probabilities of default for individual risk ratings over the loss emergence period and loss given default. Since standard 
loss factors are applied to large pools of loans, even minor changes in these factors could significantly affect the Corporation's 
determination of the appropriateness of the allowance for credit losses. To illustrate, if recent loss experience dictated that the 
estimated standard loss factors would be changed by five percent (of the estimate) across all loan risk ratings, the allowance for 
loan losses as of December 31, 2014 would change by approximately $24 million. Loss emergence periods are used to determine 
the most appropriate default horizon associated with the calculation of probabilities of default. Loss emergence periods tend to 
lengthen during benign economic periods and shorten during periods of economic distress.  Considered in isolation, lengthening 
the loss emergence period assumption would result in an increase to the allowance for credit losses.  Because standard loss factors 
are applied to pools of loans based on the Corporation's internal risk rating system, 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 
and incorporated in a qualitative adjustment. The Corporation may also include qualitative adjustments intended to capture the 
impact of certain other uncertainties that exist but are not yet reflected in the standard reserve factors.  These qualitative adjustments 
are based on management’s analysis of factors such as portfolios where recent historical losses exceed expected losses or known 
recent  events  are  expected  to  alter  risk  ratings  once  evidence  is  acquired,  observable  macroeconomic  metrics,  including 
consideration of regional metrics within the Corporation's footprint, and a qualitative assessment of the lending environment, 
including underwriting standards, current economic and political conditions, and other factors affecting credit quality. Deterioration 
in  metrics  and  credit  trends  included  in  this  analysis  would  result  in  an  increase  to  the  qualitative  adjustment  increasing  the 
allowance for credit losses. For example, if energy prices remain low for an extended period, risk ratings for Middle Market-
Energy customers could deteriorate beyond management's expectations, which could result in an increase to the allowance for 
credit losses.

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. 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. A substantial majority of the allowance is 
assigned to business segments. Any earnings impact resulting from actual outcomes differing from management estimates would 
primarily affect the Business Bank segment.

VALUATION METHODOLOGIES

Fair Value Measurement of Level 3 Financial Instruments

Fair value measurement applies whenever accounting guidance requires or permits assets or liabilities to be measured at 
fair value. 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 includes information about the fair value hierarchy, 
the extent to which fair value is used to measure assets and liabilities and the valuation methodologies and key inputs used. At 
December 31, 2014, assets and liabilities measured using observable inputs that are classified as Level 1 or Level 2 represented 

F-37

 
 
98.5 percent and 99.9 percent 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.  These 
unobservable assumptions reflect estimates of assumptions market participants would use in pricing the asset or liability. Valuation 
techniques include the use of option pricing models, discounted cash flow models and similar techniques. Fair value measurements 
for assets and liabilities where limited or no observable market data exists are based primarily upon estimates which cannot be 
determined with precision and in many cases may not reflect amounts exchanged in a current sale of the financial instrument.  
Changes in market conditions may reduce the availability of quoted prices or observable data.  For example, reduced liquidity in 
the capital markets or changes in secondary market activities could result in observable market inputs becoming unavailable. 
Therefore, when market data is not available, the Corporation would use valuation techniques requiring more management judgment 
to estimate the appropriate fair value.

 At December 31, 2014, Level 3 financial assets recorded at fair value on a recurring basis totaled $140 million, or less 
than one percent of total assets. This included auction-rate securities with a fair value of $136 million at December 31, 2014. 
Changes in the fair value are recorded in other comprehensive income (loss) and reviewed quarterly for possible other-than-
temporary impairment. The fair value at December 31, 2014 was determined using an income approach based on a discounted 
cash flow model utilizing two significant assumptions in the model: discount rate (including a liquidity risk premium) and workout 
period. The discount rate was calculated using credit spreads of the underlying collateral or similar securities plus a liquidity risk 
premium. The liquidity risk premium was derived from the rate at which various types of auction-rate securities had been redeemed 
or sold. The workout period was based on an assessment of publicly available information on efforts to re-establish functioning 
markets for these securities and the Corporation's redemption experience. Changes in these significant assumptions could result 
in different valuations. For example, an increase or decrease in the liquidity premium of 100 basis points could change the fair 
value by $2 million at December 31, 2014. 

At December 31, 2014, Level 3 financial assets recorded at fair value on a nonrecurring basis totaled $68 million, or less 
than one percent of total assets, and consisted primarily of impaired loans and foreclosed property. At December 31, 2014, there 
were no financial liabilities recorded at fair value on a nonrecurring basis. 

GOODWILL  

Goodwill 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 Business 
Bank, the Retail Bank and Wealth Management. At December 31, 2014 and 2013, goodwill totaled $635 million, including $380 
million allocated to the Business Bank, $194 million allocated to the Retail Bank and $61 million allocated to Wealth Management. 
The goodwill impairment test is a two-step test. The first step of the goodwill impairment 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, the second step must be performed to determine the implied fair value of the reporting unit's goodwill and 
the amount of goodwill impairment, if any. 

Reporting units are not legal entities, Therefore, determining the carrying value of reporting units requires the use of 
judgment. In performing the annual impairment test, the carrying value of each reporting unit is the greater of economic or regulatory 
capital. The Corporation assigns economic capital using internal management methodologies on the basis of each reporting unit's 
credit, operational and interest rate risks, as well as goodwill. To determine regulatory capital, each reporting unit is assigned 
sufficient capital such that their respective Tier 1 ratio, based on allocated risk-weighted assets, is the same as that of the Corporation.  
Using this two-pronged approach, the Corporation's equity is fully allocated to its reporting units except for capital held primarily 
for the risk associated with the securities portfolio which is assigned to the Finance segment of the Corporation. 

Determining the fair value of reporting units is a subjective process involving the use of estimates and judgments related 
to the selection of inputs such as future cash flows, discount rates, comparable public company multiples, applicable control 
premiums and economic expectations used in determining the interest rate environment. The estimated fair values of the reporting 
units are 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  consider  a  combination  of  earnings,  equity  and  other  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 accordingly incorporate a control premium. For the income approach, 
estimated future cash flows and terminal value are discounted. Estimated future cash flows are derived from internal forecasts and 
economic  expectations  for  each  reporting  unit  which  incorporate  uncertainty  factors  inherent  to  long-term  projections.  The 
applicable discount rate is based on the imputed cost of equity capital appropriate for each reporting unit, which incorporates the 
risk-free rate of return, the level of non-diversified risk associated with companies with characteristics similar to the reporting 
unit, a size risk premium and a market equity risk premium.  

The annual test of goodwill impairment was performed as of the beginning of the third quarter 2014. The Corporation's 
assumptions  included  maintaining  the  low  Federal  funds  target  rate  through  mid-2015  with  modest  increases  thereafter  until 
eventually reaching a normal interest rate environment. At the conclusion of the first step of the annual goodwill impairment tests 

F-38

performed in the third quarter 2014, the estimated fair values of all reporting units substantially exceeded their carrying amounts, 
including goodwill. The results of the annual test of the goodwill impairment test for each reporting unit were subjected to stress 
testing as appropriate.  

Economic conditions impact the assumptions related to interest and growth rates, loss rates and imputed cost of equity 
capital. The fair value estimates for each reporting unit incorporated current economic and market conditions, including the recent 
Federal Reserve announcements and the impact of legislative and regulatory changes, to the extent known and as described above. 
However, further weakening in the economic environment, such as adverse changes in interest rates, a decline in the performance 
of the reporting units or other factors could cause the fair value of one or more of the reporting units to fall below their carrying 
value,  resulting  in  a  goodwill  impairment  charge.  Additionally,  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.

For further information about the Corporation's goodwill accounting policy, refer to Note 1 to the consolidated financial 

statements.

PENSION PLAN ACCOUNTING

The Corporation has defined benefit pension plans in effect for substantially all full-time employees hired before January 
1, 2007. Benefits under the plans are based on years of service, age and compensation. Assumptions are made 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, the rate of compensation increase and the estimated 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 detailed 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 invested in certain collective investment and mutual funds, common 
stocks, U.S. Treasury and other U.S. government agency securities, and corporate and municipal bonds and notes. The rate of 
compensation increase is based on reviewing recent annual pension-eligible compensation increases as well as the expectation of 
future increases. Mortality rate assumptions are based on mortality tables published by third-parties such as the Society of Actuaries 
(SOA), 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 assumptions used to calculate 2015 expense for the defined benefit pension plans were a discount rate of 4.28 percent, 
a long-term rate of return on plan assets of 6.75 percent and a rate of compensation increase of 3.75 percent. The Corporation 
adopted the RP-2014 mortality tables and the MP-2014 mortality improvement scales issued by the SOA in October 2014, with 
certain entity-specific adjustments. The new mortality assumptions increased the projected benefit obligations for the qualified 
and non-qualified defined benefit pension plans by approximately $119 million and $17 million, respectively, at December 31, 
2014 and increased expected 2015 pension expense by approximately $25 million. Had the new mortality tables been adopted as 
published, expected 2015 pension expense would have increased by approximately $34 million. Defined benefit pension expense 
in 2015 is expected to increase approximately 14 percent to about $45 million from the $39 million recorded in 2014, primarily 
driven by a decrease in the discount rate and the impact of changes in mortality assumptions, partially offset by the benefit from 
a $350 million cash contribution from the Corporation in December 2014. 

Changing the 2015 key actuarial assumptions discussed above by 25 basis points would have the following impact on 

defined benefit pension expense in 2015:

 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.  In 2014, the actual return on plan 
assets in the qualified defined benefit pension plan was $278 million, compared to an expected return on plan assets of $131 
million. In 2013, the actual return on plan assets was $136 million, compared to an expected return on plan assets of $132 million. 
Total pretax losses recognized in accumulated other comprehensive loss at December 31, 2014 were $593 million for the qualified 

F-39

defined  benefit  pension  plan  and  $79  million  for  the  non-qualified  defined  benefit  pension  plan. Actuarial  pretax  net  losses 
recognized in other comprehensive income (loss) for the year ended December 31, 2014 were $196 million for the qualified defined 
benefit pension plan and $38 million for the non-qualified defined benefit pension plan. For further information, refer to Note 1 
to the consolidated financial statements.

Defined benefit pension expense is recorded in “employee benefits” expense on the consolidated statements of income 
and is allocated to business segments based on the segment's share of salaries expense. Accordingly, defined benefit pension 
expense was allocated approximately 43 percent, 28 percent, 24 percent and 5 percent to the Retail Bank, Business Bank, Wealth 
Management and Finance segments, respectively, in 2014. 

INCOME TAXES

The calculation of the Corporation's income tax provision and tax-related accruals is complex and requires the use of 
estimates and judgments. 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. 
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. The Corporation 
is subject to audit by taxing authorities that could question and/or challenge the tax positions taken by the Corporation.  

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

Changes in the estimate of accrued taxes occur due to changes in tax law, interpretations of existing tax laws, new judicial 
or regulatory guidance, and 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.

(a)  Tier 1 capital and risk-weighted assets as defined by regulation.
(b)  Estimated ratios based on the standardized approach in the final rule for the U.S. adoption of the Basel III regulatory capital framework, 

excluding most elements of AOCI, as fully phased in.

The Tier 1 common capital ratio removes preferred stock and qualifying trust preferred securities from Tier 1 capital as 
defined by and calculated in conformity with bank regulations. The Basel III common equity Tier 1 capital ratio further adjusts 
Tier 1 common capital and risk-weighted assets to account for the final rule approved by U.S. banking regulators in July 2013 for 
the U.S. adoption of the Basel III regulatory capital framework. The final Basel III capital rules are effective January 1, 2015 for 
banking organizations subject to the standardized approach.  The tangible common equity ratio removes preferred stock and the 
effect of intangible assets from capital and the effect of intangible assets from total assets and tangible common equity per share 
of common stock removes the effect of intangible assets from common shareholders' equity per share of common stock. The 
Corporation believes these measurements are meaningful measures of capital adequacy used by investors, regulators, management 
and others to evaluate the adequacy of common equity and to compare against other companies in the industry.

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  the  Corporation's  SEC  reports 
(accessible on the SEC's website at www.sec.gov or on the Corporation's website at www.comerica.com), actual results could 
differ materially from forward-looking statements and future results could differ materially from historical performance due to a 
variety of reasons, including but not limited to, the following factors:

• 
• 

• 
• 

• 
• 

• 

• 

• 

• 

• 
• 
• 
• 

general political, economic or industry conditions, either domestically or internationally, may be less favorable than expected;

Corporation's business and operations;
the Corporation relies on other companies to provide certain key components of its business infrastructure, and certain 
failures could materially adversely affect operations;
noninterest expenses are important to the Corporation's profitability, but are subject to a number of factors, some of which 
are not in the Corporation's control;
changes in the financial markets, including fluctuations in interest rates and their impact on deposit pricing, could adversely 
affect the Corporation's net interest income and balance sheet;
any reduction in the Corporation's credit rating could adversely affect the Corporation and/or the holders of its securities;
unfavorable developments concerning credit quality could adversely impact the Corporation's financial results;
the soundness of other financial institutions could adversely affect the Corporation;
the introduction, implementation, withdrawal, success and timing of business initiatives and strategies may be less successful

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 Business Bank, the Retail Bank and Wealth Management. The Corporation operates 
in three primary geographic markets: Michigan, California and Texas. For further discussion of each business segment and primary 
geographic market, 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.

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 in the entity's outstanding voting 
stock and uses 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.  Certain amounts in the financial statements for prior years have been reclassified to conform to current financial 
statement presentation.

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 ownership of the entity’s outstanding voting stock. Variable interests are defined as contractual ownership or other 
money interests in an entity that change with fluctuations in the entity’s net asset value. The primary beneficiary is required to 
consolidate the VIE. The primary beneficiary is defined as the party that 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 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 the entity’s operation and financial policies, which is generally presumed to exist if the Corporation owns more 
than a 20 percent voting interest in the entity. 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.

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

financial statements.

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

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.

F-48

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

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. 

Trading securities, investment securities available-for-sale, derivatives and deferred compensation plan liabilities 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,  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 upon quoted prices for identical instruments traded in active markets.

Level 2

Level 3

Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical 
or similar instruments in markets that are not 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  trading  and  investment 
securities, as well as certain derivatives designated as fair value hedges. 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, and 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. Transfers of assets or liabilities between levels 
of the fair value hierarchy are recognized at the beginning of the reporting period, when applicable.

Cash and due from banks, federal funds sold and interest-bearing deposits with banks
Due to their short-term nature, the carrying amount of these instruments approximates the estimated fair value.  As such, the 
Corporation classifies the estimated fair value of these instruments as Level 1.

Trading securities and associated deferred compensation plan liabilities
Trading securities include securities held for trading purposes as well as assets held related to employee deferred compensation 
plans. Trading 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 trading securities include assets related to employee 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 an active exchange, such as the New York Stock Exchange. Deferred compensation plan liabilities represent 
the fair value of the obligation to the employee, which corresponds to the fair value of the invested assets. Level 2 trading 
securities include municipal bonds and residential mortgage-backed securities issued by U.S. government-sponsored entities 

F-49

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

and corporate debt securities. The methods used to value trading securities are the same as the methods used to value investment 
securities, discussed below.

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. 
The fair value is based on what secondary markets are currently offering for portfolios with similar characteristics. As such, 
the Corporation classifies both loans held-for-sale subjected to nonrecurring fair value adjustments and the estimated fair 
value of loans held-for sale as Level 2.

Investment securities
Investment securities available-for-sale are recorded at fair value on a recurring basis. The Corporation discloses estimated 
fair values of investment securities held-to-maturity, which is determined in the same manner as investment securities available-
for-sale. 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 residential mortgage-backed securities issued by U.S. government agencies and U.S. government-sponsored entities 
and 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. Auction-rate securities comprise Level 3 investment securities available-for-sale. Due to the lack of a 
robust  secondary  auction-rate  securities  market  with  active  fair  value  indicators,  fair  value  for  all  periods  presented  was 
determined using an income approach based on a discounted cash flow model. The discounted cash flow model utilizes two 
significant inputs: discount rate and workout period. The discount rate was calculated using credit spreads of the underlying 
collateral or similar securities plus a liquidity risk premium. The liquidity risk premium was derived from the rate at which 
various types of similar auction-rate securities had been redeemed or sold. The workout period was based on an assessment 
of publicly available information on efforts to re-establish functioning markets for these securities and the Corporation's own 
redemption experience. Significant increases in any of these inputs in isolation would result in a significantly lower fair value. 
The  Corporate  Development  Department,  with  appropriate  oversight  and  approval  provided  by  senior  management,  is 
responsible for determining the valuation methodology for auction-rate securities and for updating significant inputs based 
on changes to the factors discussed above. Valuation results, including an analysis of changes to the valuation methodology 
and significant inputs, are provided to senior management for review on a quarterly basis.

Loans
The Corporation does not record loans at fair value on a recurring basis. However, the Corporation may establish a specific 
allowance for an impaired loan based on the fair value of the underlying collateral. Such loan values are reported as nonrecurring 
fair value measurements.  Collateral values supporting individually evaluated impaired 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 impaired loan as Level 3. The 
Special Assets Group is responsible for performing quarterly credit quality reviews for all impaired loans as part of the quarterly 
allowance for loan losses process overseen by the Chief Credit Officer, during which valuation adjustments to updated collateral 
values are determined.

The Corporation discloses fair value estimates for loans.  The estimated fair value is determined based on characteristics such 
as loan category, repricing features and remaining maturity, and includes prepayment and credit loss estimates. For variable 
rate business loans that reprice frequently, the estimated fair value is based on carrying values adjusted for estimated credit 
losses inherent in the portfolio at the balance sheet date. For other business loans and retail loans, fair values are estimated 
using a discounted cash flow model that employs a discount rate that reflects the Corporation's current pricing for loans with 
similar characteristics and remaining maturity, adjusted by an amount for estimated credit losses inherent in the portfolio at 
the balance sheet date. The rates take into account the expected yield curve, as well as an adjustment for prepayment risk, 
when applicable.  The Corporation classifies the estimated fair value of loans held for investment as Level 3.

Customers’ liability on acceptances outstanding and acceptances outstanding
Customers' liability on acceptances outstanding is included in "accrued income and other assets" and acceptances outstanding 
are included in  "accrued expenses and other liabilities" on the consolidated balance sheets. Due to their short-term nature, 
the  carrying  amount  of  these  instruments  approximates  the  estimated  fair  value.   As  such,  the  Corporation  classifies  the 
estimated fair value of these instruments as Level 1.

F-50

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

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 that use primarily 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 being 
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/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. The Corporation assessed 
the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and 
determined that the credit valuation adjustments were not significant to the overall valuation of its derivatives. As a result, 
the Corporation classifies its over-the-counter derivative valuations in Level 2 of the fair value hierarchy. Examples of Level 
2 derivative instruments are interest rate swaps and energy derivative and foreign exchange contracts.

Warrants which contain a net exercise provision or a non-contingent put right embedded in the warrant agreement are accounted 
for as derivatives and recorded at fair value on a recurring basis using a Black-Scholes valuation model.  The Black-Scholes 
valuation model utilizes five inputs: risk-free rate, expected life, volatility, exercise price, and the per share market value of 
the underlying company. The Corporation holds a portfolio of warrants for generally nonmarketable equity securities with a 
fair value of $4 million at December 31, 2014, included in "accrued income and other assets" on the consolidated balance 
sheets. These warrants are primarily from non-public technology companies obtained as part of the loan origination process. 
The  Corporate  Development  Department  is  responsible  for  the  warrant  valuation  process,  which  includes  reviewing  all 
significant inputs for reasonableness, and for providing valuation results to senior management. Increases in any of these 
inputs in isolation, with the exception of exercise price, would result in a higher fair value.  Increases in exercise price in 
isolation would result in a lower fair value. The Corporation classifies warrants accounted for as derivatives as Level 3.

The Corporation also holds a derivative contract associated with the 2008 sale of its remaining ownership of Visa Inc. (Visa) 
Class B shares. 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 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. At  December 31,  2014,  the  fair  value  of  the  contract  was  a  liability  of 
$1 million. The recurring fair value of the derivative contract is based on unobservable inputs consisting of management's 
estimate of the litigation outcome, timing of litigation settlements and payments related to the derivative.  Significant increases 
in the estimate of litigation outcome and the timing of litigation settlements in isolation would result in a significantly higher 
liability fair value.  Significant increases in payments related to the derivative in isolation would result in a significantly lower 
liability fair value.  The Corporation classifies the derivative liability as Level 3.

Nonmarketable equity securities
The Corporation has a portfolio of indirect (through funds) private equity and venture capital investments with a carrying 
value and unfunded commitments of $11 million and $5 million, respectively, at December 31, 2014. These funds generally 
cannot be redeemed and the majority is not readily marketable. Distributions from these funds are received by the Corporation 
as a result of the liquidation of underlying investments of the funds and/or as income distributions. It is estimated that the 
underlying assets of the funds will be liquidated over a period of up to 15 years. Recently issued federal regulations will 
require the Corporation to sell certain of these funds prior to liquidation. The investments are accounted for either on the cost 
or equity method and are individually reviewed for impairment on a quarterly basis by comparing the carrying value to the 
estimated fair value. These investments may be carried at fair value on a nonrecurring basis when they are deemed to be 
impaired and written down to fair value. Where there is not a readily determinable fair value, the Corporation estimates fair 
value for indirect private equity and venture capital investments based on the net asset value, as reported by the fund, after 
indication that the fund adheres to applicable fair value measurement guidance. On a quarterly basis, the Corporate Development 
Department  is  responsible,  with  appropriate  oversight  and  approval  provided  by  senior  management,  for  performing  the 
valuation procedures and updating significant inputs, as are primarily provided by the underlying fund's management. The 
Corporation classifies fair value measurements of nonmarketable equity securities as Level 3.

The Corporation also holds restricted equity investments, primarily Federal Home Loan Bank (FHLB) and Federal Reserve 
Bank (FRB) stock. Restricted equity securities are not readily marketable and are recorded at cost (par value) in "accrued 
income and other assets" on the consolidated balance sheets and evaluated for impairment based on the ultimate recoverability 
of the par value. No significant observable market data for these instruments is available. The Corporation considers the 

F-51

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

profitability and asset quality of the issuer, dividend payment history and recent redemption experience when determining the 
ultimate recoverability of the par value. The Corporation’s investment in FHLB stock totaled $7 million and $48 million at 
December 31, 2014 and 2013, respectively, and its investment in FRB stock totaled $85 million at both December 31, 2014 
and 2013. The Corporation believes its investments in FHLB and FRB stock are ultimately recoverable at par. Therefore, the 
carrying amount for these restricted equity investments approximates fair value. The Corporation classifies the estimated fair 
value of such investments as Level 1.

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  foreclosure, 
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. The Special Assets Group 
obtains updated independent market prices and appraised values, as  required by state regulation or deemed necessary based 
on market conditions, and determines if additional write-downs are necessary.  On a quarterly basis, senior management 
reviews all other real estate and determines whether the carrying values are reasonable, based on the length of time elapsed 
since receipt of independent market price or appraised value and current market conditions. When management determines 
that the fair value of other real estate requires additional adjustments, either as a result of a non-current appraisal or when 
there is no observable market price, the Corporation classifies the other real estate as Level 3.

Deposit liabilities
The estimated fair value of checking, savings and certain money market deposit accounts is represented by the amounts payable 
on demand. The estimated fair value of term deposits is calculated by discounting the scheduled cash flows using the period-
end rates offered on these instruments. As such, the Corporation classifies the estimated fair value of deposit liabilities as 
Level 2.

Short-term borrowings
The  carrying  amount  of  federal  funds  purchased,  securities  sold  under  agreements  to  repurchase  and  other  short-term 
borrowings approximates the estimated fair value. As such, the Corporation classifies the estimated fair value of short-term 
borrowings as Level 1.

Medium- and long-term debt
The carrying value of variable-rate FHLB advances approximates the estimated fair value. The estimated fair value of the 
Corporation's remaining variable- and fixed-rate medium- and long-term debt is based on quoted market values when available. 
If  quoted  market  values  are  not  available,  the  estimated  fair  value  is  based  on  the  market  values  of  debt  with  similar 
characteristics. The Corporation classifies the estimated fair value of medium- and long-term debt as Level 2.

Credit-related financial instruments
Credit-related financial instruments include unused commitments to extend credit and letters of credit. These instruments 
generate ongoing fees which are recognized over the term of the commitment.  In situations where credit losses are probable, 
the  Corporation  records  an  allowance. The  carrying  value  of  these  instruments  included  in  "accrued  expenses  and  other 
liabilities" on the consolidated balance sheets, which includes the carrying value of the deferred fees plus the related allowance, 
approximates the estimated fair value. The Corporation classifies the estimated fair value of credit-related financial instruments 
as Level 3.

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

Other Short-Term Investments

Other short-term investments include trading securities and loans held-for-sale. 

Trading securities are carried at fair value. Realized and unrealized gains or losses on trading securities are included in 

“other noninterest income” on the consolidated statements of income.

Loans held-for-sale, typically residential mortgages originated with the intent to sell, are carried at the lower of cost or 
fair value. Fair value is determined in the aggregate for each portfolio. Changes in fair value are included in “other noninterest 
income” on the consolidated statements of income.

Investment Securities

Securities not held for trading purposes are classified as available-for-sale or held-to-maturity. Only those debt securities 
for which management has the intent and ability to hold to maturity are classified as held-to-maturity and recorded at amortized 

F-52

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

cost. Securities available-for-sale are recorded at fair value, with unrealized gains and losses, net of income taxes, reported as a 
separate component of other comprehensive income (loss) (OCI).

Securities transferred from available-for-sale to held-to-maturity are reclassified at fair value on the date of transfer. The 
net unrealized gain (loss) at the date of transfer is included in historical cost and amortized over the remaining life of the related 
securities as a yield adjustment consistent with the amortization of the net unrealized gain (loss) included in accumulated other 
comprehensive loss on the same securities, resulting in no impact to net income.

Investment  securities  are  reviewed  quarterly  for  possible  other-than-temporary  impairment  (OTTI).  In  determining 
whether OTTI exists for debt securities in an unrealized loss position, the Corporation assesses the likelihood of selling the security 
prior to the recovery of its amortized cost basis. If the Corporation intends to sell the debt security or it is more likely than not that 
the Corporation will be required to sell the debt security prior to the recovery of its amortized cost basis, the debt security is written 
down to fair value, and the full amount of any impairment charge is recorded as a loss in “net securities gains” in the consolidated 
statements of income. If the Corporation does not intend to sell the debt security and it is more likely than not that the Corporation 
will not be required to sell the debt security prior to recovery of its amortized cost basis, only the credit component of any impairment 
of a debt security is recognized as a loss in “net securities gains” on the consolidated statements of income, with the remaining 
impairment recorded in OCI.

The OTTI review for equity securities includes an analysis of the facts and circumstances of each individual investment 
and  focuses  on  the  severity  of  loss,  the  length  of  time  the  fair  value  has  been  below  cost,  the  expectation  for  that  security’s 
performance, the financial condition and near-term prospects of the issuer, and management’s intent and ability to hold the security 
to recovery. A decline in value of an equity security that is considered to be other-than-temporary is recorded as a loss in “net 
securities (losses) gains” on the consolidated statements of income.

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.

Loans and leases acquired in business combinations are initially recorded at fair value with no carryover of any existing 
allowance for loan losses. Acquired loans with evidence of credit quality deterioration at acquisition are reviewed to determine if 
it is probable that the Corporation will not be able to collect all contractual amounts due, including both principal and interest.  
When both conditions exist, such loans are accounted for as purchased credit-impaired (PCI) loans. The Corporation generally 
aggregates PCI loans into pools of loans based on common risk characteristics.

The Corporation estimates the total cash flows expected to be collected from the pools of acquired PCI loans, which 
include undiscounted expected principal and interest, using credit risk, interest rate and prepayment risk models that incorporate 
management's best estimate of current key assumptions such as default rates, loss severity and payment speeds. The excess of the 
undiscounted total cash flows expected to be collected over the fair value of the related PCI loans represents the accretable yield, 
which is recognized as interest income on a level-yield basis over the life of the related loan pools. The difference between the 
undiscounted contractual principal and interest and the undiscounted total cash flows expected to be collected is the nonaccretable 
difference, which reflects the impact of estimated credit losses and other factors. Subsequent increases in expected cash flows will 
result in a recovery of any previously recorded allowance for loan losses, to the extent applicable, and a reclassification from 
nonaccretable difference to accretable yield, which is recognized prospectively over the then remaining lives of the loan pools. 
Subsequent decreases in expected cash flows will result in an impairment charge to the provision for loan losses, resulting in an 
addition to the allowance for loan losses, and a reclassification from accretable yield to nonaccretable difference. A loan disposal, 
which may include a loan sale, receipt of payment in full from the borrower or foreclosure, results in removal of the loan from the 
acquired PCI loan pool at its allocated carrying amount. Refinanced or restructured loans remain within the acquired PCI loan 
pools.

For acquired loans not deemed credit-impaired at acquisition, the difference between the initial fair value and the unpaid 

principal balance is recognized as interest income on a level-yield basis over the lives of the related loans.

The  Corporation  assesses  all  loan  modifications  to  determine  whether  a  restructuring  constitutes  a  troubled  debt 
restructuring (TDR). A restructuring is considered a TDR when a borrower is experiencing financial difficulty and the Corporation 
grants a concession to the borrower. TDRs on accrual status at the original contractual rate of interest are considered performing.  

F-53

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

Nonperforming  TDRs  include  TDRs  on  nonaccrual  status  and  loans  which  have  been  renegotiated  to  less  than  the  original 
contractual rates (reduced-rate loans). All TDRs are considered impaired loans.

Loan Origination Fees and Costs

Substantially all loan origination fees and costs are deferred and amortized to net interest income of 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 $267 million and $287 million at December 31, 2014 and 
2013, 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  are  defined  as  those  belonging  to  the  commercial,  real  estate  construction,  commercial  mortgage,  lease  financing  and 
international loan portfolios.  Retail loans consist of traditional residential mortgage, home equity and other consumer loans.

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

Allowance for Loan Losses

The  allowance  for  loan  losses  represents  management’s  assessment  of  probable,  estimable  losses  inherent  in  the 
Corporation’s loan portfolio. The allowance for loan losses includes specific allowances, based on individual evaluations of certain 
loans, and allowances for homogeneous pools of loans with similar risk characteristics. 

The Corporation individually evaluates certain impaired loans on a quarterly basis and establishes specific allowances 
for such loans, if required. A loan is considered impaired when it is probable that interest or principal payments will not be made 
in accordance with the contractual terms of the loan agreement. Consistent with this definition, all loans for which the accrual of 
interest has been discontinued (nonaccrual loans) are considered impaired. The Corporation individually evaluates nonaccrual 
loans with book balances of $2 million or more and accruing loans whose terms have been modified in a TDR. The threshold for 
individual evaluation is revised on an infrequent basis, generally when economic circumstances change significantly. Specific 
allowances for impaired loans are estimated using one of several methods, including the estimated fair value of underlying collateral, 
observable  market  value  of  similar  debt  or  discounted  expected  future  cash  flows.  Collateral  values  supporting  individually 
evaluated impaired loans are evaluated quarterly. Either appraisals are obtained or appraisal assumptions are updated at least 
annually unless conditions dictate increased frequency. The Corporation may reduce the collateral value based upon the age of the 
appraisal and adverse developments in market conditions.

Loans which do not meet the criteria to be evaluated individually are evaluated in homogeneous pools of loans with 
similar risk characteristics. Business loans are assigned to pools based on the Corporation's internal risk rating system. Internal 
risk ratings are assigned to each business loan at the time of approval and are subjected to subsequent periodic reviews by the 
Corporation’s senior management, generally at least annually or more frequently upon the occurrence of a circumstance that affects 
the credit risk of the loan. For business loans not individually evaluated, losses inherent to the pool are estimated by applying 
standard reserve factors to outstanding principal balances. Standard reserve factors are based on estimated probabilities of default 
for each internal risk rating, set to a default horizon based on an estimated loss emergence period, and loss given default. These 
factors are evaluated quarterly and updated annually, unless economic conditions necessitate a change, giving consideration to 
count-based borrower risk rating migration experience and trends, recent charge-off experience, current economic conditions and 
trends, changes in collateral values of properties securing loans, and trends with respect to past due and nonaccrual amounts. 

The allowance for business loans not individually evaluated 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 (i) risk factors that have not been fully addressed in internal risk ratings, (ii) imprecision in the risk rating system 
resulting from inaccuracy in assigning and/or entering risk ratings in the loan accounting system, (iii) market conditions and (iv) 
model imprecision. Risk factors that have not been fully addressed in internal risk ratings may include portfolios where recent 
historical losses exceed expected losses or known recent events are expected to alter risk ratings once evidence is acquired, portfolios 
where a certain level of concentration introduces added risk, or changes in the level and quality of experience held by lending 
management. An additional allowance for risk rating errors is calculated based on the results of risk rating accuracy assessments 
performed on samples of business loans conducted by the Corporation's asset quality review function, a function independent of 
F-54

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

the lending and credit groups responsible for assigning the initial internal risk rating at the time of approval. Qualitative adjustments 
for market conditions are determined based on an established framework. The determination of the appropriate adjustment is based 
on  management's  analysis  of  observable  macroeconomic  metrics,  including  consideration  of  regional  metrics  within  the 
Corporation's  footprint,  internal  credit  risk  movement  and  a  qualitative  assessment  of  the  lending  environment,  including 
underwriting standards, current economic and political conditions, and other factors affecting credit quality. 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 assumption. 

In the second quarter 2014, the Corporation enhanced the approach used to determine the standard reserve factors used 
in estimating the allowance for credit losses, which had the effect of capturing certain elements in the standard reserve component 
that had formerly been included in the qualitative assessment. The impact of the change was largely neutral to the total allowance 
for loan losses at June 30, 2014. However, because standard reserves are allocated to the segments at the loan level, while qualitative 
reserves are allocated at the portfolio level, the impact of the methodology change on the allowance of each segment reflected the 
characteristics of the individual loans within each segment's portfolio, causing segment reserves to increase or decrease accordingly.

In the first quarter 2013, the Corporation enhanced the approach utilized for determining standard reserve factors by 
changing from a dollar-based migration method for developing probability of default statistics to a count-based method. Under 
the dollar-based method, each dollar that moved to default received equal weight in the determination of standard reserve factors 
for each internal risk rating. As a result, the movement of larger loans impacted standard reserve factors more than the movement 
of smaller loans. By moving to a count-based approach, where each loan that moves to default receives equal weighting, unusually 
large or small loans will not have a disproportionate influence on the standard reserve factors. The change resulted in a $40 million 
increase to the allowance for loan losses at March 31, 2013.  

The allowance for retail loans not individually evaluated is determined by applying estimated loss rates to various pools 
of loans within the portfolios with similar risk characteristics. Estimated loss rates for all pools are updated quarterly, incorporating 
factors such as recent charge-off experience, current economic conditions and trends, changes in collateral values of properties 
securing loans (using index-based estimates), and trends with respect to past due and nonaccrual amounts.

Loans acquired in business combinations are initially recorded at fair value, which includes an estimate of credit losses 
expected to be realized over the remaining lives of the loans, and therefore no corresponding allowance for loan losses is recorded 
for these loans at acquisition. Methods utilized to estimate any subsequently required allowance for loan losses for acquired loans 
not deemed credit-impaired at acquisition are similar to originated loans; however, the estimate of loss is based on the unpaid 
principal balance less any remaining purchase discount.

The total allowance for loan losses is sufficient to absorb incurred losses inherent in the total portfolio. Unanticipated 
economic events, including political, economic and regulatory instability in countries where the Corporation has loans, could cause 
changes in the credit characteristics of the portfolio and result in an unanticipated increase in the allowance. Significant increases 
in current portfolio exposures, as well as the inclusion of additional industry-specific portfolio exposures in the allowance, could 
also increase the amount of the allowance. Any of these events, or some combination thereof, 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. The provision for loan losses and recoveries 

on loans previously charged off are added to the allowance.

 Allowance for Credit Losses on Lending-Related Commitments

The allowance for credit losses on lending-related commitments provides for probable losses inherent in lending-related 
commitments, including unused commitments to extend credit and letters of credit. The allowance for credit losses on lending-
related commitments includes allowances based on homogeneous pools of letters of credit and unused commitments to extend 
credit within each internal risk rating. A probability of draw estimate is applied to the commitment amount, and the result is 
multiplied by standard reserve factors consistent with business loans. In general, the probability of draw for letters of credit is 
considered certain for all letters of credit supporting loans and for letters of credit assigned an internal risk rating generally consistent 
with regulatory defined substandard or doubtful. Other letters of credit and all unfunded commitments have a lower probability 
of draw. 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 reflected in the “provision for credit losses” on the consolidated 
statements of income.

Nonperforming Assets

Nonperforming  assets  consist  of  nonaccrual  loans,  including  loans  held-for-sale,  reduced-rate  loans  and  foreclosed 

property.

F-55

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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. Business 
loans typically require individual evaluation and management judgment to determine the timing and amount of principal charge-
offs. The past-due status of a business loan is one of many indicative factors considered in determining the collectibility 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  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, and 
are classified as TDRs. All other consumer loans are generally not placed on nonaccrual status and are charged off at no later than 
120 days past due, 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. Income on such loans is then recognized only to the extent that cash is received and 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.

PCI loans are recorded at fair value at acquisition date. Although the PCI loans may be contractually delinquent, the 
Corporation does not classify these loans as past due or nonperforming as the loans were written down to fair value at the acquisition 
date and the accretable yield is recognized in interest income over the remaining life of the loan. 

Foreclosed property (primarily real estate) is initially recorded at fair value, less costs to sell, at the date of foreclosure 
and subsequently carried at the lower of cost or fair value, less estimated costs to sell. 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, any excess of the related loan balance over fair value (less estimated 
costs to sell) of the property acquired is charged 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 on 
the straight-line method, is charged to operations 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.

Software

Capitalized software is stated at cost, less accumulated amortization. Capitalized software includes purchased software 
and capitalizable application development costs associated with internally-developed software. Amortization, computed on the 
straight-line method, is charged to operations over 5 years, the estimated useful life of the software. Capitalized software is included 
in “accrued income and other assets” on the consolidated balance sheets.

Goodwill and Core Deposit 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 Business Bank, the Retail Bank and Wealth Management.

The Corporation performs its annual evaluation of goodwill impairment in the third quarter of each year and on an interim 
basis if events or changes in circumstances between annual tests suggest additional testing may be warranted to determine if 
goodwill might be impaired. The goodwill impairment test is a two-step test. The first step of the goodwill impairment 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, the second step must be performed to determine the implied fair value of the 

F-56

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

reporting unit's goodwill and the amount of goodwill impairment, if any.  The implied fair value of goodwill is determined as if 
the reporting unit were being acquired in a business combination. If the implied fair value of goodwill exceeds the goodwill assigned 
to the reporting unit, there is no impairment. If the goodwill assigned to a reporting unit exceeds the implied fair value of goodwill, 
an impairment charge would be recorded for the excess. 

In performing the annual impairment test, the carrying value of each reporting unit is the greater of economic or regulatory 
capital. The Corporation assigns economic capital using internal management methodologies on the basis of each reporting unit's 
credit, operational and interest rate risks, as well as goodwill.  To determine regulatory capital, each reporting unit is assigned 
sufficient capital such that their respective Tier 1 ratio, based on allocated risk-weighted assets, is the same as that of the Corporation.  
Using this two-pronged approach, the Corporation's equity is fully allocated to its reporting units except for capital held primarily 
for the risk associated with the securities portfolio which is assigned to the Finance segment of the Corporation. 

The estimated fair values of the reporting units are 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 consider a combination of 
earnings,  equity  and  other  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 accordingly incorporate a 
control premium. For the income approach, estimated future cash flows and terminal value are discounted.  Estimated future cash 
flows are derived from internal forecasts and economic expectations for each reporting unit which incorporate uncertainty factors 
inherent to long-term projections. The applicable discount rate is based on the imputed cost of equity capital appropriate for each 
reporting unit, which incorporates the risk-free rate of return, the level of non-diversified risk associated with companies with 
characteristics similar to the reporting unit, an entity-specific risk premium and a market equity risk premium. Determining the 
fair value of reporting units is a subjective process involving the use of estimates and judgments related to the selection of inputs 
such  as  future  cash  flows,  discount  rates,  comparable  public  company  multiples,  applicable  control  premiums  and  economic 
expectations used in determining the interest rate environment.

The Corporation may choose to perform a qualitative assessment to determine whether the first step of the impairment 
test should be performed in future periods if certain factors indicate that impairment is unlikely. Factors which could be 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, events affecting the Corporation as a whole or its reporting 
units individually and previous results of goodwill impairment tests.

Core deposit intangibles are amortized on an accelerated basis, based on the estimated period the economic benefits are 
expected to be received. Core deposit 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 core deposit 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 by comparing the carrying value to the estimated fair value. The 
amount by which the carrying value exceeds the fair value that is determined to be other-than-temporary 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 in 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 
F-57

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

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 current earnings 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 effective portion of the gain 
or loss on the derivative instrument is reported as a component of other comprehensive income and reclassified into earnings in 
the same period or periods during which the hedged transaction affects earnings. The remaining gain or loss on the derivative 
instrument in excess of the cumulative change in the present value of future cash flows of the hedged item (i.e., the ineffective 
portion), if any, is recognized in current earnings during the period of change. For derivative instruments not designated as hedging 
instruments, the gain or loss is recognized in current earnings during the period of change. 

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 $700 million notional of fair value hedges 
of medium and long-term debt issued prior to 2006. This method allows for the assumption of zero hedge ineffectiveness 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 and for each reporting period 
thereafter to assess whether the derivative used has been and is expected to be highly effective in offsetting changes in the fair 
value or cash flows of the hedged item. All components of each derivative instrument’s gain or loss are included in the assessment 
of hedge effectiveness. Net hedge ineffectiveness is recorded in “other noninterest income” on the consolidated statements of 
income.

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

Short-Term Borrowings

Securities sold under agreements to repurchase are treated as collateralized borrowings and are recorded at amounts equal 
to the cash received. The contractual terms of the agreements to repurchase may require the Corporation to provide additional 
collateral if the fair value of the securities underlying the borrowings declines during the term of the agreement.

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 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 (the retirement-eligible date). 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

The following summarizes the Corporation’s revenue recognition policies as they relate to certain noninterest income 

line items in the consolidated statements of income.

Service charges on deposit accounts include fees for banking services provided, overdrafts and non-sufficient funds. 
Revenue  is  generally  recognized  in  accordance  with  published  deposit  account  agreements  for  retail  accounts  or  contractual 
agreements for commercial accounts.

F-58

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

Fiduciary income includes fees and commissions from asset management, custody, recordkeeping, investment advisory 
and other services provided to personal and institutional trust customers. Revenue is recognized on an accrual basis at the time 
the services are performed and are based on either the market value of the assets managed or the services provided.

Commercial lending fees primarily include fees assessed on the unused portion of commercial lines of credit ("unused 
commitment fees") and syndication agent fees. Unused commitment fees are recognized when earned. Syndication agent fees are 
generally recognized when the transaction is complete.

Card fees includes primarily bankcard interchange revenue which is recorded as revenue when earned. 

Defined Benefit Pension and Other Postretirement Costs

Defined benefit pension costs are included in “salaries and benefits expense" on the consolidated statements of income 
and 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 assumptions include demographic assumptions such as retirement age and mortality, a compensation rate increase, 
a discount rate used to determine the current benefit obligation 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, amortization of prior service cost and amortization of net 
actuarial gains or losses. The market-related value of 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 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.

Postretirement benefits are recognized in “salaries and benefits expense" on the consolidated statements of income during 
the average remaining service period of participating employees expected to receive benefits under the plan or the average remaining 
future lifetime of retired participants currently receiving benefits under the plan.

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. 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 loss carry-back capacity, future reversals of existing taxable 
temporary differences, and assumptions made regarding future events. A valuation allowance is provided when it is more likely 
than not that some portion of the deferred tax asset will not be realized. 

The Corporation classifies interest and penalties on income tax liabilities in the “provision for income taxes” on the 

consolidated statements of income.

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., nonvested restricted stock and 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 performance-
based restricted stock units granted under the Corporation’s stock plans and warrants using the treasury stock method, if dilutive. 

F-59

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

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”, “federal funds sold” 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 Adopted Accounting Pronouncement

Effective January 1, 2014, the Corporation early adopted Accounting Standards Update (ASU)  No. 2014-01, “Investments-
Equity  Method  and  Joint  Ventures  (Topic  323): Accounting  for  Investments  in  Qualified Affordable  Housing  Projects,”  an 
amendment to GAAP  which enables companies that invest in affordable housing projects that qualify for the low-income housing 
tax credit (LIHTC) to elect to use the proportional amortization method if certain conditions are met. Under the proportional 
amortization method, the initial investment cost of the project is amortized in proportion to the amount of tax credits and other 
benefits received, with the results of the investment presented on a net basis as a component of the provision for income taxes. 
Previously, LIHTC investments were accounted for under the cost or equity method, and the amortization was recorded as a 
reduction to other noninterest income, with the tax credits and other benefits received recorded as a component of the provision 
for income taxes. The Corporation believes the proportional amortization method more appropriately represents the economics of 
LIHTC investments and provides users with a better understanding of the returns from such investments than the cost or equity 
method. 

The cumulative effect of the retrospective application of the change in amortization method was a $3 million decrease 
to both "accrued income and other assets" and "retained earnings" on the consolidated balance sheets as of January 1, 2013. The 
consolidated  financial  statements  have  been  retrospectively  adjusted  to  reflect  the  prior  period  effect  of  the  adoption  of  the 
amendment, which resulted in increases of $56 million and $52 million to both "other noninterest income" and "provision for 
income taxes" for the years ended December 31, 2013 and 2012, respectively. The adoption of ASU 2014-01 had no effect on net 
income or earnings per common share for any period presented.

Pending Accounting Pronouncements 

In January 2014, the FASB issued ASU No. 2014-04, “Receivables – Troubled Debt Restructurings by Creditors (Subtopic 
310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure,” (ASU 2014-04), 
which clarifies when an in-substance foreclosure or repossession of residential real estate property occurs, requiring a creditor to 
reclassify the loan to other real estate. According to ASU 2014-04, a consumer mortgage loan should be reclassified to other real 
estate either upon the creditor obtaining legal title to the real estate collateral or when the borrower voluntarily conveys all interest 
in the real estate property to the creditor through a deed in lieu of foreclosure or similar legal agreement. ASU 2014-04 also clarifies 
that a creditor should not delay reclassification when a borrower has a legal right of redemption. The Corporation's current practice 
is to delay reclassification of foreclosed residential real estate to other real estate until the redemption period, if any, has expired. 
The Corporation expects to prospectively adopt ASU 2014-04 in the first quarter 2015 and does not expect the adoption to have 
a material effect on the Corporation's financial condition and results of operations. 

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” (ASU 2014-09), 
which is intended to improve and converge the financial reporting requirements for revenue contracts with customers.  Previous 
GAAP comprised broad revenue recognition concepts along with numerous industry-specific requirements.  The new guidance 
establishes a five-step model which entities must follow to recognize revenue and removes inconsistencies and weaknesses in 
existing guidance.  ASU 2014-09 is effective for annual and interim periods beginning after December 15, 2016, and must be 
retrospectively applied.  Entities will have the option of presenting prior periods as impacted by the new guidance or presenting 
the cumulative effect of initial application along with supplementary disclosures.  Early adoption is prohibited.  The Corporation 
is currently evaluating the impact of adopting ASU 2014-09.

In June 2014, the FASB issued ASU No. 2014-12, “Compensation-Stock Compensation (Topic 718): Accounting for 
Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite 
Service  Period,”  (ASU  2014-12). The  new  guidance  requires  that  a  performance  target  that  affects  vesting  and  that  could  be 

F-60

achieved after the requisite service period be treated as a performance condition.  ASU 2014-12 is effective for annual and interim 
periods beginning after December 15, 2015, with early adoption permitted. The Corporation's current accounting treatment of 
performance conditions for employees who are or become retirement eligible prior to the achievement of the performance target 
are consistent with ASU 2014-12 and, as such, does not expect the new guidance to have a material effect on the Corporation’s 
financial condition and results of operations. The Corporation expects to prospectively adopt ASU 2014-12 in the first quarter 
2015.

NOTE 2 – 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.

Trading securities, investment securities available-for-sale, derivatives and deferred compensation plan liabilities 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, 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.

Refer to Note 1 for further information about the fair value hierarchy, 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.

ASSETS AND LIABILITIES RECORDED AT FAIR VALUE ON A NONRECURRING BASIS

The Corporation may be required, from time to time, 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. All assets recorded at fair value on a nonrecurring basis were classified as Level 3 at December 31, 
2014 and 2013 and are presented in the following table.  No liabilities were recorded at fair value on a nonrecurring basis at 
December 31, 2014 and 2013.

(a)  Commitments  to  fund  additional  investments  in  nonmarketable  equity  securities  recorded  at  fair  value  on  a  nonrecurring  basis  were 

insignificant at December 31, 2014 and 2013.

Level 3 assets recorded at fair value on a nonrecurring basis at December 31, 2014 and 2013 included loans for which a 
specific allowance was established based on the fair value of collateral and other real estate for which fair value of the properties 
was less than the cost basis.  For both asset classes, 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 quantifiable inputs, 
although they are used in the determination of fair value.

The  following  table  presents  quantitative  information  related  to  the  significant  unobservable  inputs  utilized  in  the 
Corporation's Level 3 recurring fair value measurement as of December 31, 2014 and December 31, 2013. The Corporation's 
Level 3 recurring fair value measurements include auction-rate securities where fair value is determined using an income approach 
based on a discounted cash flow model. The inputs in the table below reflect management's expectation of continued illiquidity 
in the secondary auction-rate securities market due to a lack of market activity for the issuers remaining in the portfolio, a lack of 
market incentives for issuer redemptions, and the expectation for a continuing low interest rate environment.

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 also 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 carrying amount and estimated fair value of financial instruments not recorded at fair value in their entirety on a 

recurring basis on the Corporation’s consolidated balance sheets are as follows:

At December 31, 2014, the Corporation had 142 securities in an unrealized loss position with no credit impairment, 
including 80 residential mortgage-backed securities, 43 equity and other non-debt auction-rate preferred securities, 17 state and 
municipal auction-rate securities, one corporate auction-rate debt security and one U.S. Treasury security. As of December 31, 
2014, approximately 89 percent of the aggregate par value of auction-rate securities have been redeemed or sold since acquisition, 
of which approximately 95 percent were redeemed at or above cost. The unrealized losses for these securities resulted from changes 
in market interest rates and liquidity. The Corporation ultimately expects full collection of the carrying amount of these securities, 
does not intend to sell the securities in an unrealized loss position, and it is not more-likely-than-not that the Corporation will be 
required to sell the securities in an unrealized loss position prior to recovery of amortized cost. The Corporation does not consider 
these securities to be other-than-temporarily impaired at December 31, 2014.

The following table summarizes the amortized cost and fair values of debt securities by contractual maturity. Securities 
with multiple maturity dates are classified in the period of final maturity. 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.

Included in the contractual maturity distribution in the table above were residential mortgage-backed securities available-
for-sale with a total amortized cost and fair value of $7.2 billion and $7.3 billion, respectively, and residential mortgage-backed 
securities held-to-maturity with a total amortized cost and fair value of $1.9 billion. The actual cash flows of mortgage-backed 
securities may differ from contractual maturity as the borrowers of the underlying loans may exercise prepayment options.

At December 31, 2014, investment securities with a carrying value of $2.9 billion were pledged where permitted or 
required by law to secure $1.9 billion of liabilities, primarily public and other deposits of state and local government agencies and 
derivative instruments.

Total loans
(a) 
(b) 

(c) 

Includes all loans not included in the categories of special mention, substandard or nonaccrual.
Special mention loans are accruing loans that 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. This category is generally consistent with the "special mention" 
category as defined by regulatory authorities.
Substandard loans are accruing loans that 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 also are distinguished by the distinct possibility of loss in the future if 
these weaknesses are not corrected.  PCI loans are included in the substandard category. This category is generally consistent with the "substandard" category as defined by 
regulatory authorities.

(d)  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. A significant majority of nonaccrual loans are generally consistent with the "substandard" category and 
the remainder are generally consistent with the "doubtful" category as defined by regulatory authorities.

(e)  Primarily loans to real estate developers.
(f) 

Primarily loans secured by owner-occupied real estate.

(b)  Loan restructurings whereby the original loan is restructured into two notes:  an "A" note, which generally reflects the portion of the modified 

loan which is expected to be collected; and a "B" note, which is either fully charged off or exchanged for an equity interest.

(c)  Primarily loans to real estate developers.
(d)  Primarily loans secured by owner-occupied real estate.
(e)  Includes bankruptcy loans for which the court has discharged the borrower's obligation and the borrower has not reaffirmed the debt.

At December 31, 2014 and 2013, commitments to lend additional funds to borrowers whose terms have been modified 

in TDRs totaled $3 million and $4 million, respectively.

The majority of the modifications considered to be TDRs that occurred during the years ended December 31, 2014 and 
2013  were  principal  deferrals.  The  Corporation  charges  interest  on  principal  balances  outstanding  during  deferral  periods.  
Additionally, none of the modifications involved forgiveness of principal.  As a result, the current and future financial effects of 
the recorded balance of loans considered to be TDRs that were restructured during the years ended December 31, 2014 and 2013 
were insignificant.  

On an ongoing basis, the Corporation monitors the performance of modified loans to their restructured terms. In the event 
of a subsequent default, the allowance for loan losses continues to be reassessed on the basis of an individual evaluation of the 
loan.

The following table presents information regarding the recorded balance at December 31, 2014 and 2013 of loans modified 
by principal deferral during the years ended December 31, 2014 and 2013, and those principal deferrals which experienced a 
subsequent default during the same periods.  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, is considered a subsequent default.

Purchased Credit-Impaired Loans

Acquired loans are initially recorded at fair value with no carryover of any allowance for loan losses. Loans acquired 
with evidence of credit quality deterioration at acquisition for which it was probable that the Corporation would not be able to 
collect all contractual amounts due were accounted for as PCI loans. The Corporation aggregated the acquired PCI loans into pools 
of loans based on common risk characteristics.  

 No allowance for loan losses was required on the acquired PCI loan pools at both December 31, 2014 and 2013. The 
carrying  amount  of  acquired  PCI  loans  included  in  the  consolidated  balance  sheet  and  the  related  outstanding  balance  at

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.

As outlined below, the Corporation has a concentration of credit risk with the automotive industry. Loans to automotive 
dealers and to borrowers involved with automotive production are reported as automotive, as management believes these loans 
have similar economic characteristics that might cause them to react similarly to changes in economic conditions. This aggregation 
involves the exercise of judgment. Included in automotive production are: (a) original equipment manufacturers and Tier 1 and 
Tier 2 suppliers that produce components used in vehicles and whose primary revenue source is automotive-related (“primary” 
defined as greater than 50%) and (b) other manufacturers that produce components used in vehicles and whose primary revenue 
source is automotive-related. Loans less than $1 million and loans recorded in the Small Business loan portfolio were excluded 
from the definition. Outstanding loans, included in "commercial loans" on the consolidated balance sheets, and total exposure 
from loans, unused commitments and standby letters of credit to companies related to the automotive industry were as follows:

The Corporation performs its annual evaluation of goodwill impairment in the third quarter of each year and on an interim 
basis if events or changes in circumstances between annual tests indicate goodwill might be impaired. In 2014 and 2013, the annual 
test of goodwill impairment was performed as of the beginning of the third quarter. At the conclusion of the first step of the annual 
and interim goodwill impairment tests performed in 2014 and 2013 the estimated fair values of all reporting units exceeded their 
carrying amounts, including goodwill, indicating that goodwill was not impaired. There have been no events since the annual test 
performed in the third quarter 2014 that would indicate that it was more likely than not that goodwill had become impaired.

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 reviewed 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. Master netting arrangements effectively reduce credit risk 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 beyond certain risk limits. At December 31, 2014, counterparties with bilateral collateral agreements had pledged 
$245 million of marketable investment securities and deposited $264 million of cash with the Corporation to secure the fair value 
of contracts in an unrealized gain position, and the Corporation had pledged $2 million of investment securities 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. 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.

The aggregate fair value of all derivative instruments with credit-risk-related contingent features that were in a liability 
position on December 31, 2014 was $6 million, for which the Corporation had pledged collateral of $2 million in the normal 
course of business. The credit-risk-related contingent features require the Corporation’s debt to maintain an investment grade 
credit rating from each of the major credit rating agencies. If the Corporation’s debt were to fall below investment grade, the 
counterparties to the derivative instruments could require additional overnight collateral on derivative instruments in net liability 
positions. If the credit-risk-related contingent features underlying these agreements had been triggered on December 31, 2014, 
the Corporation would have been required to assign an additional $4 million of collateral to its counterparties.

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 

F-79

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

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 conducting hedging transactions 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.

subject to credit or market risk and are not reflected in the consolidated balance sheets.

(b)  Net derivative assets are included in “accrued income and other assets” and net derivative liabilities are included in “accrued expenses 
and other liabilities” on the consolidated balance sheets. Included in the fair value of net derivative assets and net derivative liabilities are 
credit valuation adjustments reflecting counterparty credit risk and credit risk of the Corporation. The fair value of net derivative assets 
included credit valuation adjustments for counterparty credit risk of $2 million at both December 31, 2014 and 2013.

Risk Management

As an end-user, the Corporation employs a variety of financial instruments for risk management purposes, including cash 
instruments, such as investment securities, as well as derivative instruments. Activity related to these instruments is centered 
predominantly in the interest rate markets and mainly involves interest rate swaps. Various other types of instruments also may 

F-81

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

be used to manage exposures to market risks, including interest rate caps and floors, total return swaps, foreign exchange forward 
contracts and foreign exchange swap agreements.

The Corporation entered into interest rate swap agreements related to medium- and long-term debt for interest rate risk 
management purposes. These interest rate swap agreements effectively modify the Corporation’s exposure to interest rate risk by 
converting fixed-rate debt to a floating rate. These agreements involve the receipt of fixed-rate interest amounts in exchange for 
floating-rate interest payments over the life of the agreement, without an exchange of the underlying principal amount. Risk 
management fair value interest rate swaps generated net interest income of $72 million for each of the years ended December 31, 
2014  and  2013. The  Corporation  recognized  an  insignificant  amount  of  gain  for  the  year  ended  December 31,  2014  and  an 
insignificant amount of loss for the year ended December 31, 2013 in "other noninterest income" in the consolidated statements 
of income for the ineffective portion of risk management derivative instruments designated as fair value hedges of fixed-rate debt.

Foreign  exchange  rate  risk  arises  from  changes  in  the  value  of  certain  assets  and  liabilities  denominated  in  foreign 
currencies. The Corporation employs spot and forward contracts in addition to swap contracts to manage exposure to these and 
other  risks. The  Corporation  recognized  an  insignificant  amount  of  net  gains  for  the  year  ended  December 31,  2014  and  an 
insignificant amount of net losses for the year ended December 31, 2013 on risk management derivative instruments used as 
economic hedges in "other noninterest income" in the consolidated statements of income.

 The  following  table  summarizes  the  expected  weighted  average  remaining  maturity  of  the  notional  amount  of  risk 
management interest rate swaps and the weighted average interest rates associated with amounts expected to be received or paid 
on interest rate swap agreements as of December 31, 2014 and 2013.

Management believes these hedging strategies achieve the desired relationship between the rate maturities of assets and 
funding sources which, in turn, reduce the overall exposure of net interest income to interest rate risk, although there can be no 
assurance that such strategies will be successful.

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. For those customer-initiated derivative contracts which were not offset or 
where the Corporation holds a speculative position within the limits described above, the Corporation recognized $1 million of 
net gains in “other noninterest income” in the consolidated statements of income for each of the years ended December 31, 2014 
and 2013.

contracts and are recorded in the consolidated balance sheets. Changes in fair value are recognized in the consolidated statements

The  Corporation  maintains  an  allowance  to  cover  probable  credit  losses  inherent  in  lending-related  commitments, 
including unused commitments to extend credit, letters of credit and financial guarantees. At December 31, 2014 and 2013, the 
allowance for credit losses on lending-related commitments, included in “accrued expenses and other liabilities” on the consolidated 
balance sheets, was $41 million and $36 million, 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 
$30 million and $28 million at December 31, 2014 and 2013, respectively, for probable 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 2022. 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  $316  million  and  $259  million, 
respectively, of the $4.0 billion and $4.4 billion standby and commercial letters of credit outstanding at December 31, 2014 and 
2013, respectively.

The carrying value of the Corporation’s standby and commercial letters of credit, included in “accrued expenses and 
other liabilities” on the consolidated balance sheets, totaled $55 million at December 31, 2014, including $44 million in deferred 
fees and $11 million in the allowance for credit losses on lending-related commitments. At December 31, 2013, the comparable 
amounts were $59 million, $51 million and $8 million, respectively.

The following table presents a summary of criticized standby and commercial letters of credit at December 31, 2014 and 
December 31, 2013. The Corporation's criticized list is consistent with the Special mention, Substandard and Doubtful categories

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 had it entered into the derivative instruments directly with the borrower. The notional amount of such credit risk participation 
agreement reflects the pro-rata share of the derivative instrument, consistent with its share of the related participated loan. As of 
December 31, 2014 and 2013, the total notional amount of the credit risk participation agreements was approximately $598 million 
and  $614  million,  respectively,  and  the  fair  value,  included  in  customer-initiated  interest  rate  contracts  recorded  in  "accrued 
expenses and other liabilities" on the consolidated balance sheets, was insignificant for each period. The maximum estimated 
exposure to these agreements, as measured by projecting a maximum value of the guaranteed derivative instruments, assuming 
100 percent default by all obligors on the maximum values, was approximately $7 million at both December 31, 2014 and 2013. 
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, 2014, the weighted average 
remaining maturity of outstanding credit risk participation agreements was 2.9 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 $1 million and $2 million at December 31, 2014 and 2013, respectively.

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  LIHTC. The  Corporation  also  directly  invests  in  limited 
partnerships and LLCs which invest in community development projects which generate similar tax credits to investors. 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. While the 
partnership/LLC agreements allow the limited partners/investor members, through a majority vote, to remove the general partner/
managing member, this right is not deemed to be substantive as the general partner/managing member can only be removed for 
cause.

The Corporation accounts for its interests in LIHTC entities using the proportional amortization method. Exposure to 
loss as a result of the Corporation’s involvement with LIHTC entities at December 31, 2014 was limited to approximately $389 
million. Ownership interests in other community development projects which generate similar tax credits to investors (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 other tax credit entities at December 31, 2014 was limited to approximately $8 million.

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  ($130  million  at 
December 31, 2014). Amortization and other write-downs of LIHTC investments are presented on a net basis as a component of 

F-84

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

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, 2014, 2013 and 2012.

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

The Bank is a member of the FHLB, which provides short- and long-term funding to its members through advances 
collateralized by real-estate related assets.  Actual borrowing capacity is contingent upon the amount of collateral available to be 
pledged to the FHLB.  At December 31, 2014, $14 billion of real estate-related loans were pledged to the FHLB as blanket collateral 
for potential future borrowings of approximately $6 billion.

In the second quarter 2014, the Corporation issued $350 million of 2.125% senior notes due 2019, which were swapped 

to a floating rate based on six-month LIBOR.  Proceeds were used for general corporate purposes.  

In the third quarter 2014, the Corporation issued $250 million of 3.80% subordinated notes due 2026, which were swapped 
to a floating rate based on six-month LIBOR.  Proceeds were used for general corporate purposes.  Also in the third quarter 2014, 
the Corporation exercised its option to redeem, at par, $150 million of 8.375% subordinated notes, originally due in 2024.  A gain 
of $32 million was recognized on the early redemption, primarily from the recognition of the unamortized value of a related, 
previously terminated interest rate swap.

NOTE 13 - SHAREHOLDERS’ EQUITY

The Federal Reserve completed its 2014 Comprehensive Capital Analysis and Review (CCAR) of the Corporation's 
2014-2015 capital plan in March 2014 and did not object to the capital distributions contemplated in the plan. The capital plan 
provides for up to $236 million of equity repurchases for the four-quarter period ending March 31, 2015. At December 31, 2014, 
up to $59 million remained available for share repurchases under the capital plan.

Repurchases of common stock under the share repurchase program authorized by the Board of Directors of the Corporation 
in 2010 totaled 5.2 million shares at an average price paid of $47.91 per share, 7.4 million shares at an average price paid of $38.63 
per share and 10.1 million shares at an average price paid of $30.21 per share in 2014, 2013 and 2012, respectively. There is no 
expiration date for the Corporation's share repurchase program.   

At December 31, 2014, the Corporation had 13.2 million warrants outstanding to purchase 11.2 million common shares 
at a weighted-average exercise price of $29.45. Outstanding  warrants were exercisable at the date of grant and expire in 2018. 
Approximately 361 thousand shares of common stock were issued upon exercise of warrants in 2014. There were no warrant 
exercises in 2013 and 2012. 

At December 31, 2014, the Corporation had 11.2 million shares of common stock reserved for warrant exercises, 14.7 
million shares of common stock reserved for stock option exercises and restricted stock unit vesting and 2.1 million shares of 
restricted stock outstanding to employees and directors under share-based compensation plans.

The Corporation has share-based compensation plans under which it awards shares of restricted stock and restricted stock 
units to key executive officers, directors and key personnel, and stock options to executive officers and key personnel of the 
Corporation and its subsidiaries. Restricted stock vests over periods ranging from three years to five years, restricted stock units 
vest over periods ranging from one year to four years, and stock options vest over periods ranging from one year to four years. 
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 originally provided for a grant of up to 17.9

million common shares, plus shares under certain plans that are forfeited, expire or are canceled. At December 31, 2014, 9.0 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 employee and director 
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 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.

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

assumptions are summarized in the following table:

The Corporation expects to satisfy the exercise of stock options, the vesting of restricted stock units and future grants of

NOTE 17 - EMPLOYEE BENEFIT PLANS

Defined Benefit Pension and Postretirement Benefit Plans

The Corporation has a qualified and a non-qualified defined benefit pension plan, which together provide benefits for 
substantially all full-time employees hired before January 1, 2007 who continue to meet the eligibility requirements of the plans. 
Salaries and benefits expense included defined benefit pension expense of $39 million, $86 million and $75 million in the years 
ended December 31, 2014, 2013 and 2012, respectively, for the plans. Benefits under the defined benefit plans are based primarily 
on years of service, age and compensation during the five highest paid consecutive calendar years occurring during the last ten 
years before retirement.

The Corporation’s postretirement benefit plan continues to provide 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. 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. Employee benefits expense 
included postretirement benefit expense of $1 million, $2 million and $6 million in the years ended December 31, 2014, 2013 and 
2012, respectively, for the plan.

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 average life of approximately 15  years as of December 31, 
2014. 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 one 
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.

The estimated portion of balances remaining in accumulated other comprehensive income (loss) that are expected to be 

recognized as a component of net periodic benefit cost in the year ended December 31, 2015 are as follows.

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  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 and 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 operating costs) that meet or exceed a customized benchmark 
as defined in the plan 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 
36 percent to 56 percent equity securities and 44 percent to 64 percent 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.

 Collective investment funds

Fair value measurement is based upon the net asset value (NAV) provided by the administrator of the fund. Collective 
investment fund NAVs are based primarily on observable inputs, generally the quoted prices for underlying assets owned by the 
fund, and are included in Level 2 of the fair value hierarchy.

Mutual funds

Fair value measurement is based upon the 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

Fair value measurement is based upon quoted prices in an active market exchange, such as the New York Stock Exchange. 

Level 1 securities include U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets.

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.

Collateralized mortgage obligations

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.

F-95

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

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.

Securities purchased under agreements to resell

Fair value measurement is based upon independent pricing models or other model-based valuation techniques such as 

the present value of future cash flows, and is included in Level 2 of the fair value hierarchy.

 Fair Values

The fair  values of the  Corporation’s  qualified defined benefit  pension plan investments measured at  fair value on  a

There were no assets in the non-qualified defined benefit pension plan at December 31, 2014 and 2013. 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.

Cash Flows

The Corporation currently expects to make no employer contributions to the qualified and non-qualified defined benefit 

pension plans and postretirement benefit plan for the year ended December 31, 2015.

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 $22 million,  $21 million and $20 
million for the years ended December 31, 2014, 2013 and 2012, respectively.

The Corporation also provides a profit sharing plan for the benefit of substantially all employees  who work at least 1,000 
hours in a plan year and are not accruing a benefit in the defined benefit pension plan. Under the profit sharing plan, the Corporation 
makes an annual discretionary allocation to the individual account of each eligible employee ranging from 3 percent to 8 percent 
of annual compensation, determined based on combined age and years of service. The allocations are invested based on employee 
investment elections. The employee fully vests in the defined contribution pension plan after three years of service, at age 65 if 
still employed, or in the event of death while an employee. Before an employee is eligible to participate, the plan requires the 
equivalent of one year of service. The Corporation recognized $10 million, $7 million and $7 million in employee benefits expense 
for this plan for the years ended December 31, 2014, 2013 and 2012, respectively.

Deferred Compensation Plans

The Corporation offers optional deferred compensation plans under which certain employees may make an irrevocable 
election to defer incentive compensation and/or a portion of base salary until retirement or separation from the Corporation. The 
employee 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 employees, resulting in a deferred compensation 
asset, recorded in “other short-term investments” on the consolidated balance sheets that offsets the liability to employees 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 employees under the 
plan is recorded in “salaries” 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 is 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.

Income before income taxes of $870 million for the year ended December 31, 2014 included $32 million of foreign-

source income.

There was no income tax provision on securities transactions for the years ended December 31, 2014 and December 31, 

2013 and an income tax provision of $4 million on securities transactions for the year ended December 31, 2012.

The provision for income taxes does not reflect the tax effects of unrealized gains and losses on investment securities 
available-for-sale or the change in defined benefit pension and other postretirement plans adjustment included in accumulated 
other comprehensive loss. Refer to Note 14 for additional information on accumulated other comprehensive loss.

The income tax effects of transactions under the Corporation's share-based compensation plans reduced both shareholders’ 

equity and deferred tax assets by $11 million, $5 million and $16 million in 2014, 2013, and 2012 respectively.

Included in “accrued expenses and other liabilities” on the consolidated balance sheets was a $2 million liability for tax-

related interest and penalties at both December 31, 2014 and December 31, 2013.

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, an administrative authority or a court, if presented with the transactions, 
could disagree with the Corporation’s interpretation of the tax law.

A reconciliation of the beginning and ending amount of net unrecognized tax benefits follows:

 After consideration of the effect of the federal tax benefit available on unrecognized state tax benefits, the total amount 
of unrecognized tax benefits that, if recognized, would affect the Corporation’s effective tax rate was approximately $2 million at 
both December 31, 2014 and December 31, 2013.

Based on current knowledge and probability assessment of various potential outcomes, the Corporation believes that 
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.

The principal components of deferred tax assets and liabilities were as follows:

At December 31, 2014 and December 31, 2013, the Corporation determined that no valuation allowance was necessary 
on federal or state deferred tax assets. This determination was based on sufficient taxable income in the carry-back period and 
projected future reversals of existing taxable temporary differences to absorb the deferred tax assets. The remaining deferred tax 
assets will be absorbed by future reversals of existing taxable temporary differences. For further information on the Corporation’s 
valuation policy for deferred tax assets, refer to Note 1.

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, 2014, totaled $105 million at the beginning of 2014 and $79 million at the end of 2014. During 2014, new 
loans to related parties aggregated $544 million and repayments totaled $570 million.

NOTE 20 - REGULATORY CAPITAL AND RESERVE REQUIREMENTS

Reserves required to be maintained and/or deposited with the FRB are classified in interest-bearing deposits with banks. 
These reserve balances vary, depending on the level of customer deposits in the Corporation’s banking subsidiaries. The average 
required reserve balances were $430 million and $397 million for the years ended December 31, 2014 and 2013, respectively.

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 

F-99

 
 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

parent company, with prior approval from bank regulatory agencies, approximated $375 million at January 1, 2015, plus 2015 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 $380 million, $480 million and $497 million in 2014, 2013 

and 2012, respectively.

The Corporation and its U.S. banking subsidiaries are subject to various regulatory capital requirements administered by 
federal  and  state  banking  agencies.  Quantitative  measures  established  by  regulation  to  ensure  capital  adequacy  require  the 
maintenance of minimum amounts and ratios of Tier 1 and total capital (as defined in the regulations) to average and 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, 
2014 and 2013, the Corporation and its U.S. banking subsidiaries exceeded the ratios required for an institution to be considered 
“well capitalized” (total risk-based capital, Tier 1 risk-based capital and leverage ratios greater than 10 percent, 6 percent and 5 
percent, respectively). There have been no conditions or events since December 31, 2014 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.

As previously reported in the Corporation's Form 10-K for the year ended December 31, 2013 and updated in Forms 10-
Q for the quarterly periods ended March 31, 2014, June 30, 2014 and September 30, 2014, Comerica Bank, a wholly owned 
subsidiary of the Corporation, was sued in November 2011 as a third-party defendant in Butte Local Development v. Masters Group 
v. Comerica Bank (“the case”), for lender liability.  The case was tried in January 2014, in the Montana Second District Judicial 
Court for Silver Bow County in Butte, Montana ("the court"). On January 17, 2014, a jury awarded Masters $52 million against 
the Bank. Following the jury’s decision on the case, the Corporation increased its reserve for litigation-related expense, effective 
as of December 31, 2013, to $52 million. The Corporation increased its reserve related to the case to $54 million in March 2014, 
to include additional attorney's fees and costs awarded by the court.

The Corporation believes that it has meritorious defenses and appellate issues for this litigation and has appealed to the 
Montana Supreme Court, the sole appellate court for the state of Montana. The Montana Supreme Court heard oral arguments in 
September 2014 and will be rendering a written decision on the appeal.

F-100

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

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 meritorious 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. On at least a quarterly basis, the Corporation 
assesses its potential liabilities and contingencies in connection with outstanding legal proceedings utilizing the latest information 
available. On a case-by-case basis, reserves are established for those legal claims for which it is probable that a loss will be incurred 
either as a result of a settlement or judgment, and the amount of such loss can be reasonably estimated. The actual costs of resolving 
these claims may be substantially higher or lower than the amounts reserved. Based on current knowledge, and after consultation 
with legal counsel, management believes that current reserves 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, 
consolidated results of operations or consolidated cash flows.  Legal fees of $24 million for each of the years ended December 31, 
2014 and 2013, and $31 million for the year ended December 31, 2012, 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 legal reserves. The Corporation believes the 
estimate of the aggregate range of reasonably possible losses, in excess of reserves established, for all legal proceedings in which 
it is involved is from zero to approximately $36 million at December 31, 2014. This estimated aggregate range of reasonably 
possible losses is based upon currently available information for those proceedings in which the Corporation is involved, taking 
into account the Corporation’s best estimate of such losses for those cases for which such estimate can be made. For certain cases, 
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 proceedings (including the fact that many are currently in preliminary stages), the existence in 
certain 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 proceedings (including issues regarding class certification and the scope of many 
of the claims) and the attendant uncertainty of the various potential outcomes of such proceedings. 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, consolidated results of operations or consolidated cash 
flows.

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

NOTE 22 - BUSINESS SEGMENT INFORMATION

The Corporation has strategically aligned its operations into three major business segments: the Business 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 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, 2014.

Net interest income for each business segment is the total of 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 provides the business segments credits for deposits and other funds provided and charges the 
business segments for loans and other assets utilizing funds. This credit or charge is based on matching stated or implied maturities 
for these assets and liabilities. The FTP credit provided for deposits reflects the long-term value of deposits generated based on 
their  implied  maturity.  The  FTP  charge  for  funding  assets  reflects  a  matched  cost  of  funds  based  on  the  pricing  and  term 
characteristics  of  the  assets.  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 Treasury group within the Finance 
segment, where such exposures are centrally managed. The allowance for loan losses is allocated to the business segments based 
F-101

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Comerica Incorporated and Subsidiaries

on the methodology used to estimate the consolidated allowance for loan losses described in Note 1. The related provision for loan 
losses is assigned based on the amount necessary to maintain an allowance for loan 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.

In 2014, the Corporation enhanced the approach used to determine the standard reserve factors used in estimating the 
allowance for credit losses, which had the effect of capturing certain elements in the standard reserve component that had formerly 
been included in the qualitative assessment.  The impact of the change was largely neutral to the total allowance for loan losses 
at June 30, 2014.  However, because standard reserves are allocated to the segments at the loan level, while qualitative reserves 
are  allocated  at  the  portfolio  level,  the  impact  of  the  methodology  change  on  the  allowance  of  each  segment  reflected  the 
characteristics of the individual loans within each segment's portfolio, causing segment reserves to increase or decrease accordingly.  
As a result, the current year provision for credit losses within each segment is not comparable to prior period amounts.

In 2013, the Corporation changed the method of assigning the allowance for loan losses to each business segment. In 
2012,  national  probability  of  default  and  loss  given  default  statistics  were  incorporated  into  the  Corporation's  allowance 
methodology. Each business segment was assigned an allowance for loan losses based on market-specific standard reserve factors 
applied to the loans in each segment, and the difference between the total allowance required on a national basis and the market-
specific allowances was allocated based on the relative loan balances in each segment. Effective 2013, each segment was assigned 
an allowance for loan losses by applying national standard reserve factors to the loan balances in each segment by risk rating 
distribution. This change was retroactively applied to 2012. Also in 2013, the Corporation changed the method of allocating FDIC 
insurance expense to the segments as well as certain noninterest income and expense associated with commercial charge cards. 
The changes did not have a material impact on segment operating results. 

The following discussion provides information about the activities of each business segment. A discussion of the financial 
results and the factors impacting 2014 performance can be found in the section entitled "Business Segments" in the financial 
review.

The Business Bank meets the needs of middle market businesses, multinational corporations and governmental entities 
by offering various products and services, including commercial loans and lines of credit, deposits, cash management, capital 
market products, international trade finance, letters of credit, foreign exchange management services and loan syndication services.

The  Retail  Bank  includes  small  business  banking  and  personal  financial  services,  consisting  of  consumer  lending, 
consumer deposit gathering and mortgage loan origination. In addition to a full range of financial services provided to small 
business customers, this business segment offers a variety of consumer products, including deposit accounts, installment loans, 
credit cards, student loans, home equity lines of credit and residential mortgage loans.

Wealth Management offers products and services consisting of fiduciary services, private banking, retirement services, 
investment management and advisory services, investment banking and brokerage services. This business segment also offers the 
sale of annuity products, as well as life, disability and long-term care insurance products.

The Finance segment includes the Corporation’s securities portfolio and asset and liability management activities. This 
segment is responsible for managing the Corporation’s funding, liquidity and capital needs, performing interest sensitivity analysis 
and executing various strategies to manage the Corporation’s exposure to liquidity, interest rate risk and foreign exchange risk.

The Other category includes the income and expense impact of equity and cash, tax benefits not assigned to specific 
business segments, charges of an unusual or infrequent nature that are not reflective of the normal operations of the business 
segments and miscellaneous other expenses of a corporate nature.

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, 2014. 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, 2014.

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, 2014 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

Board of Directors and Shareholders
Comerica Incorporated

We have audited Comerica Incorporated and subsidiaries' internal control over financial reporting as of December 31, 2014, 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). Comerica Incorporated and subsidiaries' 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 conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). 
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control 
over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control 
over  financial  reporting,  assessing  the  risk  that  a  material  weakness  exists,  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.

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

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

In our opinion, Comerica Incorporated and subsidiaries maintained, in all material respects, effective internal control over financial 
reporting as of December 31, 2014, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the 
2014 consolidated financial statements of Comerica Incorporated and subsidiaries and our report dated February 17, 2015 expressed 
an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Shareholders
Comerica Incorporated

We have audited the accompanying consolidated balance sheets of Comerica Incorporated and subsidiaries as of December 31, 
2014 and 2013, 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, 2014. These financial statements are the responsibility 
of the Corporation's management. Our responsibility is to express an opinion on these financial statements based on our audits. 

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

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position 
of Comerica Incorporated and subsidiaries at December 31, 2014 and 2013, and the consolidated results of their operations and 
their cash flows for each of the three years in the period ended December 31, 2014, 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), 
Comerica  Incorporated  and  subsidiaries’  internal  control  over  financial  reporting  as  of  December 31,  2014,  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 17, 2015 expressed an unqualified opinion thereon.
