Recovery and growth. In my mind that’s the story of 2021. 
We experienced a strong recovery from 2020, a year that 
will ever be associated with COVID-19, and our earnings 
per share were up by 33%. But beyond that, and I think 
even  more  importantly,  we  began  generating  historically 
strong  growth  in  our  business  as  we  continued  to  invest 
to  deliver  above-average  organic  growth  through  great 
customer experiences that make peoples’ lives better. 

R ECO V E RY
First the numbers. Regarding our improved performance, 
the  33%  EPS  increase  was  more  than  anything  else  the 
result of lower credit loss expenses (we used to call these 
loan loss provisions before accounting rules changed the 
term.) This expense went from $241 million in 2020 to 
just  $63,000  in  2021  as  some  of  the  worst  economic 
effects of the pandemic began to abate in our markets. 

Commercial real estate (CRE) accounted for $116 million 
of the decline. Energy was close behind at $105 million. 
However,  unlike  CRE,  where  actual  charge  offs  have 
been very modest to this point, energy loans experienced 
charge offs of 5% in 2020 as the industry struggled with 
dramatically lower prices when demand collapsed due to 
COVID-19. 

We  have  been  steadily  reducing  our  exposure  to  energy 
loans. As we entered 2016 these loans were 15.3% of our 
portfolio.  At  year  end  2021  they  stood  at  6.6%.  We’ve 
got  a  little  more  to  go  before  they  reach  “mid-single 
digits.”  We  undertook  this  reduction  because  at  such  a 
high  concentration  of  our  loans,  volatility  of  commodity 

prices  in  this  industry  created  excessive  volatility  for  our 
shareholders when oil prices declined. I don’t believe our 
investors sign up for that kind of volatility when they own 
a company like ours. I know I don’t. That said, energy loans 
will still be an important portfolio segment for us, just at 
a much lower level with reduced volatility and a focus on 
solid underwriting of great customer relationships.

In  2021  our  performance  was  also  aided  by  good 
noninterest  revenue  growth  including  trust  and  wealth 
management  (up  15.3%)  as  well  as  steadily  improving 
loan growth through the latter part of the year. 

Also  aiding  our  2021  results  was  our  continued 
outstanding  execution  getting  PPP  loans  for  businesses.  
I  wrote  extensively  last  year  of  the  historic  and  heroic 
effort of our bankers. All told, we funded $4.7 billion in 
these loans, or about 10% of our asset base. To put that 
in  perspective,  pound  for  pound  that’s  about  nine  times 
the  level  of  our  largest  competitors.  The  next  phase  of 
the  PPP  loan  program  was  to  shepherd  our  customers 
through the PPP forgiveness process. Again, our bankers 
have gone above and beyond, with about 95% of loans 
forgiven  to  date.  This  compares  with  a  current  industry 
average  of  approximately  80%  forgiven  over  the  same 
time period.

their  outstanding  growth 

run, 
Deposits  continued 
increasing  22%  for  2021  and  providing  us  with  higher 
levels  of  investable  funds.  In  fact,  as  of  year-end  we 
maintained  33%  of  our  earning  assets  in  short  term 
liquidity (think a checking account at the Federal Reserve 

C U L L E N / F R O S T   B A N K E R S ,   I N C .   P A G E   2

 
 
 
earning 15 basis points) waiting to take direct advantage 
of Fed rate hikes, or move into security purchases at higher 
yields.  This  increase  in  our  liquidity  was  a  purposeful 
strategy we  began  in  August  2020  in order to enhance 
the optionality in our balance sheet against an improved 
economy and higher rates. This level of liquid investments, 
combined with our high percentage of floating-rate loans 
and  high  levels  of  low-cost  checking  account  funding, 
combine  to  make  us  very  “asset  sensitive,”  meaning  we 
make more money when interest rates rise and less money 
when interest rates decline. 

That’s an important factor in my optimism for the future 
as  we  sit  on  the  cusp  of  several  potential  Fed  rate  hikes 

From  December  2020  to  December  2021,  loans  grew  
97% while deposits increased 167%. 

As I’ve pointed out in previous letters, these locations are 
not  retail  transaction  processing  centers,  although  some 
of that will certainly occur there. Their profitability is 70% 
driven  by  middle-market  commercial  and  small  business 
with  complementary  business  derived  from  consumer, 
private  banking,  wealth  management  and 
insurance. 
I  think  it’s  also  important  that  the  mix  of  business  we’re 
generating looks very similar to the overall company. For 
example, loans are 40% commercial and industrial (C&I), 
40% commercial real estate, and 20% consumer. They’re 
also  focused  on  our  core  segment,  with  only  three  loans

O U R   L O N G - T E R M   S U C C E S S .

as they address developing inflation. Our latest modeling 
indicated  each  25  basis  point  increase  in  the  Fed  Funds 
rate  adds  an  annualized  20-25  cents  per  share  to  our 
company’s earnings. 

G R O W T H
Our organic expansion into the Houston market that we 
announced in 2018 continues to see momentum building 
as  the  branches  mature.  We  completed  the  last  four  of 
our  25  new  branches  in  2021.  I’ve  spoken  at  length  in 
past letters about the rationale for this strategy to almost 
double our physical locations in that market. We continue 
to outperform our original pro forma goals for our three 
key program metrics and at year end we stood at:

•  $623 million of deposits (113% of our goal)

•  13,375 new relationships (128% of our goal)

•  $442 million of loans (178% of our goal)

over $10 million. Deposits are two-thirds commercial and 
one-third consumer. I should also say as to whether these 
locations are a necessary element of our growth, 87% of 
our new Houston relationships came from within five miles 
of a Frost branch.

After  the  success  we’ve  shown  executing  this  strategy  in 
Houston, in 2021 we announced two follow-on strategies. 
One,  we  are  adding  an  additional  eight  locations  in 
Houston  in  attractive  sub-markets  over  18  months.  We 
call  this  “Houston  2.0.”  It’s  important  to  note  that  these 
additional  locations  were  not  in  second-tier  markets.  
Our  analysis  shows  them  to  be  every  bit  as  good  as  our 
first 25, but as we apply our lessons and experience from 
our  initial  expansion  effort,  they  have  the  potential  to 
perform even better. 

Second,  we  announced  almost  30  new  locations  in  the 
Dallas  market  over  the  next  30  months.  These  Dallas 
locations will essentially triple our footprint in this dynamic 
market.  Our  success  in  both  the  Houston  and  Dallas 

A N N U A L   R E P O R T   2 0 2 1   P A G E   3

markets  is  important  to  our  long-term  success.  The  size 
of  these  markets  can  be  hard  to  get  your  head  around, 
but keep in mind that both Dallas and Houston each have 
about 50% more deposits than either the state of Arizona 
or the state of Colorado.

An important consideration when we decided to undertake 
an organic expansion strategy like the ones in Houston and 
Dallas was the fact we were witnessing organic customer 
growth  in  our  business.  We  believed  we  could  leverage 
this  ability  in  new  locations  in  great  markets  in  Texas. 
That  growth  was  not  an  accident.  We  had  been  steadily 
investing over time in our business and value proposition 
in order to lower customer barriers to entry and improve 
our  client  experience.  We  continued  this  effort  in  2021.  

F O R   E X A M P L E: 
•   We  introduced  $100  overdraft  grace  in  April,  where 
customers  with  a  modest  $500  direct  deposit  were 
allowed to overdraw their account by $100 without a fee. 
In 2021 it helped 48,000 families breathe a little easier.

•   We  were  one  of  the  first  banks  to  introduce  Early 
Payday  in  the  summer,  which  puts  your  direct  deposit 
in your account as much as two days earlier. It’s been a 
very popular feature and positively affects 67% of our 
consumer customers. 

•   We  entered  into  an  agreement  with  Cardtronics  that 
helped us create the largest free ATM network in Texas. 
It  also  closed  an  ATM  gap  we  had  in  the  Dallas/Fort 
Worth market by adding 350 ATMs and delivering the 
largest free ATM network in that market on the eve of 
our Dallas expansion. 

Here are just a few more examples of investments we’ve 
made over the last five years that we believe have helped 
us produce organic growth:

•  Re-architected and redesigned digital banking

•  Fraud alerts

•   Increased our customer service staff for  

better response

•   New products for affluent, emerging affluent 

 and student customers

•   Frost Connect (Bottomline Technologies) online 

treasury management services

•    Wealth Connect (eMoney) financial planning system

These investments have helped drive outstanding customer 
satisfaction and exciting organic relationship growth. 

F O R   E X A M P L E:
•   Our fourth quarter 2021 consumer customer satisfac-
tion  (CSAT)  scores  are  95%  in  our  contact  center, 
97% in digital and 97% in branch. The branch scores 
are 98% in Houston at a time we’ve almost doubled our 
employee base while navigating through a pandemic.

•   We won the J.D. Power award for highest retail banking 
customer satisfaction in Texas for the 12th year in a row.

•   This  has  led  to  record  growth  in  net  new  checking 
households in 2021 of 26,664, which is 210% of our 
previous  full  year  record  in  2019.  Our  growth  in  the 
overall total number of checking households was 7.4% 
and in Houston it was double that at 14%. 

•   Houston’s  net  new  checking  household  growth  is 
helping propel our growth. Compared to 2018, before 
our first expansion branch opened, some months were 
as  low  as  50-60  net  new  checking  households  per 
month. In 2021, down months were 500-600. On a 
full year basis, post expansion net checking household 
growth  is  over  four  times  higher  than  before  our  first 
new branch opened in Houston in late 2018.

•  Mobile account opening

•   In 2021, 37% of our consumer checking accounts were 

•  Mobile consumer real estate loan application

opened digitally. 

•  Instant-issue debit cards

•  Zelle P2P payment platform

•  Apple and Android Pay

•   Organic growth is an emerging strength. Consider that 
in  the  four  years  since  2017,  our  compound  annual 
growth rate in net new checking households is 35%. 

•   The growth in our total number of commercial relation-
ships  increased  7%  in  2021,  in  line  with  the  overall 
growth in consumer.

supply of our most important asset, our people, we recently 
raised  our  minimum  wage  to  $20  per  hour.  This  was  a 
direct result of the tight labor market and our commitment 
to  hire  top  quality  talent  to  provide  our  customers  with 
world class service.  

We  also  look  forward  to  completing  our  effort  to  offer 
single-family  mortgages  later  this  year.  This  product  will 
respond  to  customer  demand,  leverage  our  expanding 
branch  network  and  offer  a  “Frost  quality”  customer 
experience.  It  also  complements  the  four  consumer 
real  estate  products  we  already  provide  —  home  equity, 
HELOC, home improvement and purchase money second 
loans, which together total $1.4 billion. 

We’re  using  best-in-class  technology  which  we  will 
into  our  non-mortgage 
ultimately  reverse  engineer 
consumer real estate products for lower costs and improved 
customer  experiences.  We  will  avoid  an  “agency  model” 
and a commissioned sales force, and we will portfolio and 
service all loans. It will be a branch-centric model that is

PART I

The disclosures set forth in this item are qualified by Item 1A. Risk Factors and the section captioned “Forward-
Looking  Statements  and  Factors  that  Could  Affect  Future  Results”  in  Item  7.  Management’s  Discussion  and 
Analysis of Financial Condition and Results of Operations of this report and other cautionary statements set forth 
elsewhere in this report.

The Corporation

Cullen/Frost  Bankers,  Inc.,  a  Texas  business  corporation  incorporated  in  1977,  is  a  financial  holding  company 
and a bank holding company headquartered in San Antonio, Texas that provides, through its subsidiaries, a broad 
array  of  products  and  services  throughout  numerous  Texas  markets.  The  terms  “Cullen/Frost,”  “the  Corporation,” 
“we,” “us” and “our” mean Cullen/Frost Bankers, Inc. and its subsidiaries, when appropriate. We offer commercial 
and consumer banking services, as well as trust and investment management, insurance, brokerage, mutual funds, 
leasing,  treasury  management,  capital  markets  advisory  and  item  processing  services.  At  December  31,  2021, 
Cullen/Frost  had  consolidated  total  assets  of  $50.9  billion  and  was  one  of  the  largest  independent  bank  holding 
companies headquartered in the State of Texas.

Our philosophy is to grow and prosper, building long-term relationships based on top quality service, high ethical 
standards,  and  safe,  sound  assets.  We  operate  as  a  locally-oriented,  community-based  financial  services 
organization, augmented by experienced, centralized support in select critical areas. Our local market orientation is 
reflected in our regional management and regional advisory boards, which are comprised of local business persons, 
professionals  and  other  community  representatives  that  assist  our  regional  management  in  responding  to  local 
banking needs. Despite this local market, community-based focus, we offer many of the products available at much 
larger money-center financial institutions.

We  serve  a  wide  variety  of  industries  including,  among  others,  energy,  manufacturing,  services,  construction, 
retail, telecommunications, healthcare, military and transportation. Our customer base is similarly diverse. While our 
loan  portfolio  has  a  concentration  of  energy-related  loans  totaling  approximately  6.6%  of  total  loans  (or  6.8% 
excluding  Paycheck  Protection  Program  loans)  at  December  31,  2021,  we  are  not  dependent  upon  any  single 
industry or customer.

Our operating objectives include expansion, diversification within our markets, growth of our fee-based income, 
and growth internally and through acquisitions of financial institutions, branches and financial services businesses. 
We generally seek merger or acquisition partners that are culturally similar and have experienced management and 
possess  either  significant  market  presence  or  have  potential  for  improved  profitability  through  financial 
management,  economies  of  scale  and  expanded  services.  From  time  to  time,  we  evaluate  merger  and  acquisition 
opportunities  and  conduct  due  diligence  activities  related  to  possible  transactions  with  other  financial  institutions 
and  financial  services  companies.  As  a  result,  merger  or  acquisition  discussions  and,  in  some  cases,  negotiations 
may take place and future mergers or acquisitions involving cash, debt or equity securities may occur. Acquisitions 
typically  involve  the  payment  of  a  premium  over  book  and  market  values,  and,  therefore,  some  dilution  of  our 
tangible  book  value  and  net  income  per  common  share  may  occur  in  connection  with  any  future  transaction.  Our 
ability to engage in certain merger or acquisition transactions, whether or not any regulatory approval is required, 
will be dependent upon our bank regulators’ views at the time as to the capital levels, quality of management and 
our overall condition and their assessment of a variety of other factors. Certain merger or acquisition transactions, 
including  those  involving  the  acquisition  of  a  depository  institution  or  the  assumption  of  the  deposits  of  any 
depository institution, require formal approval from various bank regulatory authorities, which will be subject to a 
variety of factors and considerations.

Although  Cullen/Frost  is  a  corporate  entity,  legally  separate  and  distinct  from  its  affiliates,  bank  holding 
companies such as Cullen/Frost are required to act as a source of financial strength for their subsidiary banks. The 
principal source of Cullen/Frost’s income is dividends from its subsidiaries. There are certain regulatory restrictions 
on  the  extent  to  which  these  subsidiaries  can  pay  dividends  or  otherwise  supply  funds  to  Cullen/Frost.  See  the 
section captioned “Supervision and Regulation” elsewhere in this item for further discussion of these matters.

Cullen/Frost’s  executive  offices  are  located  at  111  W.  Houston  Street,  San  Antonio,  Texas  78205,  and  its 

telephone number is (210) 220-4011.

Cullen/Frost Capital Trust II

Cullen/Frost Capital Trust II (“Trust II”) is a Delaware statutory business trust formed in 2004 for the purpose of 
issuing $120.0 million in trust preferred securities and lending the proceeds to Cullen/Frost. Cullen/Frost guarantees, 
on a limited basis, payments of distributions on the trust preferred securities and payments on redemption of the trust 
preferred securities. Trust II is a variable interest entity for which we are not the primary beneficiary. As such, the 
accounts of Trust II are not included in our consolidated financial statements. See our accounting policy related to 
consolidation  in  Note  1  -  Summary  of  Significant  Accounting  Policies  in  the  notes  to  consolidated  financial 
statements included in Item 8. Financial Statements and Supplementary Data elsewhere in this report.

Although the accounts of Trust II are not included in our consolidated financial statements, the $120.0 million in 
trust preferred securities issued by Trust II are included in the regulatory capital of Cullen/Frost during the reported 
periods.  See  the  section  captioned  “Supervision  and  Regulation  -  Capital  Requirements”  for  a  discussion  of  the 
regulatory capital treatment of our trust preferred securities.

Other Subsidiaries

Cullen/Frost has various other subsidiaries that are not significant to the consolidated entity.

Operating Segments

Our  operations  are  managed  along  two  reportable  operating  segments  consisting  of  Banking  and  Frost  Wealth 
Advisors.  See  the  sections  captioned  “Results  of  Segment  Operations”  in  Item  7.  Management’s  Discussion  and 
Analysis  of  Financial  Condition  and  Results  of  Operations  and  Note  18  -  Operating  Segments  in  the  notes  to 
consolidated financial statements included in Item 8. Financial Statements and Supplementary Data elsewhere in this 
report.

Competition

There is significant competition among commercial banks in our market areas. In addition, we also compete with 
other  providers  of  financial  services,  such  as  savings  and  loan  associations,  credit  unions,  consumer  finance 
companies, securities firms, insurance companies, insurance agencies, commercial finance and leasing companies, 
full service brokerage firms, discount brokerage firms, and financial/wealth technology (“fintech/wealthtech”) firms. 
Some of our competitors have greater resources and, as such, may have higher lending limits and may offer other 
services that are not provided by us. We generally compete on the basis of customer service and responsiveness to 
customer needs, available loan and deposit products, the rates of interest charged on loans, the rates of interest paid 
for funds, and the availability and pricing of trust, brokerage and insurance services. For further discussion, see the 
section captioned “We Operate In A Highly Competitive Industry and Market Area” in Item 1A. Risk Factors.

Supervision and Regulation

Cullen/Frost,  Frost  Bank  and  most  of  its  non-banking  subsidiaries  are  subject  to  extensive  regulation  under 
federal  and  state  laws.  The  regulatory  framework  is  intended  primarily  for  the  protection  of  depositors,  federal 
deposit insurance funds and the banking system as a whole and not for the protection of shareholders and creditors.

Significant  elements  of  the  laws  and  regulations  applicable  to  Cullen/Frost  and  its  subsidiaries  are  described 
below. The description is qualified in its entirety by reference to the full text of the statutes, regulations and policies 
that are described. Also, such statutes, regulations and policies are continually under review by Congress and state 
legislatures  and  federal  and  state  regulatory  agencies.  A  change  in  statutes,  regulations  or  regulatory  policies 
applicable to Cullen/Frost and its subsidiaries could have a material effect on our business, financial condition or our 
results of operations. 

Regulatory Agencies

Cullen/Frost  is  a  legal  entity  separate  and  distinct  from  Frost  Bank  and  its  other  subsidiaries.  As  a  financial 
holding company and a bank holding company, Cullen/Frost is regulated under the Bank Holding Company Act of 
1956, as amended (“BHC Act”), and it and its subsidiaries are subject to inspection, examination and supervision by 
the  Federal  Reserve  Board.  The  BHC  Act  provides  generally  for  “umbrella”  regulation  of  financial  holding 
companies such as Cullen/Frost by the Federal Reserve Board, and for functional regulation of banking activities by 
bank regulators, securities activities by securities regulators, and insurance activities by insurance regulators. Cullen/
Frost  is  also  under  the  jurisdiction  of  the  Securities  and  Exchange  Commission  (“SEC”)  and  is  subject  to  the 
disclosure and regulatory requirements of the Securities Act of 1933, as amended, and the Securities Exchange Act 
of 1934, as amended, as administered by the SEC. Cullen/Frost’s common stock is listed on the New York Stock 
Exchange (“NYSE”) under the trading symbol “CFR” and our Depositary Shares, each representing a 1/40th interest 
in  a  share  of  our  4.450%  Non-Cumulative  Perpetual  Preferred  Stock,  Series  B,  is  listed  on  the  NYSE  under  the 
trading symbol “CFR PrB.” Accordingly, Cullen/Frost is also subject to the rules of the NYSE for listed companies.

Frost Bank is a Texas state chartered bank and a member of the Federal Reserve System. Accordingly, the Texas 
Department of Banking and the Federal Reserve Board are the primary regulators of Frost Bank. Deposits at Frost 
Bank are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to applicable limits.

All member banks of the Federal Reserve System, including Frost Bank, are required to hold stock in the Federal 
Reserve System's Reserve Banks in an amount equal to six percent of their capital stock and surplus (half paid to 
acquire the stock with the remainder held as a cash reserve). Member banks do not have any control over the Federal 
Reserve System as a result of owning the stock and the stock cannot be sold or traded. The annual dividend rate for 
member  banks  with  total  assets  in  excess  of  approximately  $11.2  billion,  including  Frost  Bank,  is  tied  to  10-year 
U.S.  Treasuries  with  the  maximum  dividend  rate  capped  at  six  percent.  The  total  amount  of  stock  dividends  that 
Frost  Bank  received  from  the  Federal  Reserve  totaled  $532  thousand  in  2021,  $313  thousand  in  2020  and  $688 
thousand in 2019.

Most of our non-bank subsidiaries also are subject to regulation by the Federal Reserve Board and other federal 
and  state  agencies.  Frost  Brokerage  Services,  Inc.  is  regulated  by  the  SEC,  the  Financial  Industry  Regulatory 
Authority (“FINRA”) and state securities regulators. Frost Investment Advisors, LLC and Frost Investment Services, 
LLC  are  subject  to  the  disclosure  and  regulatory  requirements  of  the  Investment  Advisors  Act  of  1940,  as 
administered by the SEC. Our insurance subsidiary is subject to regulation by applicable state insurance regulatory 
agencies. Other non-bank subsidiaries are subject to both federal and state laws and regulations. Frost Bank and its 
affiliates  are  also  subject  to  supervision,  regulation,  examination  and  enforcement  by  the  Consumer  Financial 
Protection Bureau (“CFPB”) with respect to consumer protection laws and regulations.

Bank Holding Company Activities

In  general,  the  BHC  Act  limits  the  business  of  bank  holding  companies  to  banking,  managing  or  controlling 
banks and other activities that the Federal Reserve Board has determined to be so closely related to banking as to be 
a  proper  incident  thereto.  In  addition,  bank  holding  companies  that  qualify  and  elect  to  be  financial  holding 
companies may engage in any activity, or acquire and retain the shares of a company engaged in any activity, that is 
either (i) financial in nature or incidental to such financial activity (as determined by the Federal Reserve Board in 
consultation  with  the  Secretary  of  the  Treasury)  or  (ii)  complementary  to  a  financial  activity  and  does  not  pose  a 
substantial  risk  to  the  safety  and  soundness  of  depository  institutions  or  the  financial  system  generally  (as  solely 

7

determined by the Federal Reserve Board), without prior approval of the Federal Reserve Board. Activities that are 
financial  in  nature  include  securities  underwriting  and  dealing,  insurance  underwriting  and  making  merchant 
banking investments.

To maintain financial holding company status, a financial holding company and all of its depository institution 
subsidiaries must be “well capitalized” and “well managed.” A depository institution subsidiary is considered to be 
“well capitalized” if it satisfies the requirements for this status discussed in the section captioned “Prompt Corrective 
Action,”  elsewhere  in  this  item.  A  depository  institution  subsidiary  is  considered  “well  managed”  if  it  received  a 
composite rating and management rating of at least “satisfactory” in its most recent examination. A financial holding 
company’s  status  will  also  depend  upon  it  maintaining  its  status  as  “well  capitalized”  and  “well  managed”  under 
applicable  Federal  Reserve  Board  regulations.  If  a  financial  holding  company  ceases  to  meet  these  capital  and 
management requirements, the Federal Reserve Board’s regulations provide that the financial holding company must 
enter  into  an  agreement  with  the  Federal  Reserve  Board  to  comply  with  all  applicable  capital  and  management 
requirements.  Until  the  financial  holding  company  returns  to  compliance,  the  Federal  Reserve  Board  may  impose 
limitations  or  conditions  on  the  conduct  of  its  activities,  and  the  company  may  not  commence  any  of  the  broader 
financial  activities  permissible  for  financial  holding  companies  or  acquire  a  company  engaged  in  such  financial 
activities without prior approval of the Federal Reserve Board. If the company does not return to compliance within 
180 days, the Federal Reserve Board may require divestiture of the holding company’s depository institutions. Bank 
holding companies and banks must also be both well capitalized and well managed in order to acquire banks located 
outside their home state.

In order for a financial holding company to commence any new activity permitted by the BHC Act or to acquire a 
company engaged in any new activity permitted by the BHC Act, each insured depository institution subsidiary of 
the financial holding company must have received a rating of at least “satisfactory” in its most recent examination 
under  the  Community  Reinvestment  Act.  See  the  section  captioned  “Community  Reinvestment  Act”  elsewhere  in 
this item.

The Federal Reserve Board has the power to order any bank holding company or its subsidiaries to terminate any 
activity or to terminate its ownership or control of any subsidiary when the Federal Reserve Board has reasonable 
grounds to believe that continuation of such activity or such ownership or control constitutes a serious risk to the 
financial soundness, safety or stability of any bank subsidiary of the bank holding company.

The  BHC  Act,  the  Bank  Merger  Act,  the  Texas  Banking  Code  and  other  federal  and  state  statutes  regulate 
acquisitions of commercial banks and their parent holding companies. The BHC Act requires the prior approval of 
the Federal Reserve Board for the direct or indirect acquisition by a bank holding company of more than 5.0% of the 
voting shares of a commercial bank or its parent holding company. Under the Bank Merger Act, the prior approval 
of the Federal Reserve Board or other appropriate bank regulatory authority is required for a member bank to merge 
with another bank or purchase substantially all of the assets or assume any deposits of another bank. In reviewing 
applications seeking approval of merger and acquisition transactions, the bank regulatory authorities will consider, 
among  other  things,  the  competitive  effect  and  public  benefits  of  the  transactions,  the  applicant's  managerial  and 
financial resources, the capital position of the combined organization, the risks to the stability of the U.S. banking or 
financial system (e.g., systemic risk), the applicant’s performance record under the Community Reinvestment Act 
(see  the  section  captioned  “Community  Reinvestment  Act”  elsewhere  in  this  item)  and  its  compliance  with  law, 
including  fair  lending,  fair  housing  and  other  consumer  protection  laws,  and  the  effectiveness  of  the  subject 
organizations in combating money laundering activities.

Dividends and Stock Repurchases

The principal source of Cullen/Frost’s liquidity is dividends from Frost Bank. The prior approval of the Federal 
Reserve Board is required if the total of all dividends declared by a state-chartered member bank in any calendar 
year would exceed the sum of the bank’s net profits for that year and its retained net profits for the preceding two 
calendar years, less any required transfers to surplus or to fund the retirement of preferred stock. Federal law also 
prohibits  a  state-chartered,  member  bank  from  paying  dividends  that  would  be  greater  than  the  bank’s  undivided 
profits. Frost Bank is also subject to limitations under Texas state law regarding the level of dividends that may be 
paid. Under the foregoing dividend restrictions, and while maintaining its “well capitalized” status, Frost Bank could 
pay  aggregate  dividends  of  approximately  $494.1  million  to  Cullen/Frost,  without  obtaining  affirmative 
governmental approvals, at December 31, 2021. This amount is not necessarily indicative of amounts that may be 
paid or available to be paid in future periods.

8

In addition, Cullen/Frost and Frost Bank are subject to other regulatory policies and requirements relating to the 
payment  of  dividends,  including  requirements  to  maintain  adequate  capital  above  regulatory  minimums.  The 
appropriate  federal  regulatory  authority  is  authorized  to  determine  under  certain  circumstances  relating  to  the 
financial  condition  of  a  bank  holding  company  or  a  bank  that  the  payment  of  dividends  would  be  an  unsafe  or 
unsound  practice  and  to  prohibit  payment  thereof.  Additionally,  it  is  Federal  Reserve  policy  that  bank  holding 
companies  generally  should  pay  dividends  on  common  stock  only  out  of  net  income  available  to  common 
shareholders  over  the  past  year  and  only  if  the  prospective  rate  of  earnings  retention  appears  consistent  with  the 
organization's  current  and  expected  future  capital  needs,  asset  quality  and  overall  financial  condition.  Federal 
Reserve policy also provides that a bank holding company should inform the Federal Reserve reasonably in advance 
of declaring or paying a dividend that exceeds earnings for the period for which the dividend is being paid or that 
could result in a material adverse change to the bank holding company's capital structure.

In  July  2019,  the  federal  bank  regulators  adopted  final  rules  (the  “Capital  Simplifications  Rules”)  that,  among 
other things, eliminated the standalone prior approval requirement in the Basel III Capital Rules for any repurchase 
of  common  stock.  In  certain  circumstances,  Cullen/Frost’s  repurchases  of  its  common  stock  may  be  subject  to  a 
prior  approval  or  notice  requirement  under  other  regulations,  policies  or  supervisory  expectations  of  the  Federal 
Reserve Board. Any redemption or repurchase of preferred stock or subordinated debt remains subject to the prior 
approval of the Federal Reserve Board.

Transactions with Affiliates

Transactions between Frost Bank and its subsidiaries, on the one hand, and Cullen/Frost or any other subsidiary, 
on  the  other  hand,  are  regulated  under  federal  banking  law.  The  Federal  Reserve  Act  imposes  quantitative  and 
qualitative requirements and collateral requirements on covered transactions by Frost Bank with, or for the benefit 
of, its affiliates, and generally requires those transactions to be on terms at least as favorable to Frost Bank as if the 
transaction were conducted with an unaffiliated third party. 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  Federal  Reserve  Board)  from  the  affiliate,  certain  derivative  transactions  that  create  a 
credit  exposure  to  an  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. In general, any such transaction by 
Frost  Bank  or  its  subsidiaries  must  be  limited  to  certain  thresholds  on  an  individual  and  aggregate  basis  and,  for 
credit transactions with any affiliate, must be secured by designated amounts of specified collateral.

Federal  law  also  limits  a  bank’s  authority  to  extend  credit  to  its  directors,  executive  officers  and  10% 
stockholders, as well as to entities controlled by such persons. Among other things, extensions of credit to insiders 
are required to be made on terms that are substantially the same as, and follow credit underwriting procedures that 
are not less stringent than, those prevailing for comparable transactions with unaffiliated persons. Also, the terms of 
such extensions of credit may not involve more than the normal risk of non-repayment or present other unfavorable 
features and may not exceed certain limitations on the amount of credit extended to such persons individually and in 
the aggregate.

Source of Strength Doctrine

Federal Reserve Board policy and federal law require bank holding companies to act as a source of financial and 
managerial strength to their subsidiary banks. Under this requirement, Cullen/Frost is expected to commit resources 
to  support  Frost  Bank,  including  at  times  when  Cullen/Frost  may  not  be  in  a  financial  position  to  provide  such 
resources. Any capital loans by a bank holding company to any of its subsidiary banks are subordinate in right of 
payment  to  depositors  and  to  certain  other  indebtedness  of  such  subsidiary  banks.  In  the  event  of  a  bank  holding 
company’s  bankruptcy,  any  commitment  by  the  bank  holding  company  to  a  federal  bank  regulatory  agency  to 
maintain  the  capital  of  a  subsidiary  bank  will  be  assumed  by  the  bankruptcy  trustee  and  entitled  to  priority  of 
payment.

Capital Requirements

Cullen/Frost and Frost Bank are each required to comply with applicable capital adequacy standards adopted by 
the Federal Reserve Board (the “Basel III Capital Rules”). The Basel III Capital Rules require Cullen/Frost and Frost 
Bank to maintain the following:

9

•

•

•

•

A minimum ratio of Common Equity Tier 1 (“CET1”) to risk-weighted assets of at least 4.5%, plus a 2.5% 
“capital  conservation  buffer”  that  is  composed  entirely  of  CET1  capital  (resulting  in  a  minimum  ratio  of 
CET1 to risk-weighted assets of 7.0%);

A  minimum  ratio  of  Tier  1  capital  to  risk-weighted  assets  of  at  least  6.0%,  plus  the  capital  conservation 
buffer (resulting in a minimum Tier 1 capital ratio of 8.5%);

A minimum ratio of total capital (Tier 1 capital plus Tier 2 capital) to risk-weighted assets of at least 8.0%, 
plus the capital conservation buffer (resulting in a minimum total capital ratio of 10.5%); and

A minimum leverage ratio of 4.0%, calculated as the ratio of Tier 1 capital to average consolidated assets as 
reported on consolidated financial statements (known as the “leverage ratio”).

Banking institutions that fail to meet the effective minimum ratios once the capital conservation buffer is taken 
into account, as detailed above, will be subject to constraints on capital distributions, including dividends and share 
repurchases,  and  certain  discretionary  executive  compensation.  The  severity  of  the  constraints  depends  on  the 
amount of the shortfall and the institution’s “eligible retained income” (that is, the greater of (i) net income for the 
preceding four quarters, net of distributions and associated tax effects not reflected in net income and (ii) average net 
income over the preceding four quarters).

The Basel III Capital Rules and the Capital Simplification Rules also provide for a number of deductions from 
and adjustments to CET1. These include, for example, the requirement that certain deferred tax assets and significant 
investments in non-consolidated financial entities be deducted from CET1 to the extent that any one such category 
exceeds  25%  of  CET1.  Prior  to  the  adoption  of  the  Capital  Simplification  Rules  in  July  2019,  amounts  were 
deducted  from  CET1  to  the  extent  that  any  one  such  category  exceeded  10%  of  CET1  or  all  such  items,  in  the 
aggregate, exceeded 15% of CET1. The Capital Simplification Rules took effect for Cullen/Frost and Frost Bank as 
of January 1, 2020. These limitations did not impact our regulatory capital during any of the reported periods.

In  addition,  under  the  general  risk-based  capital  rules,  the  effects  of  accumulated  other  comprehensive  income 
items included in capital were excluded for the purposes of determining regulatory capital ratios. Under the Basel III 
Capital Rules, the effects of certain accumulated other comprehensive income items are not excluded; however, non-
advanced approaches banking organizations, including Cullen/Frost and Frost Bank, were able to make a one-time 
permanent election to continue to exclude these items. Both Cullen/Frost and Frost Bank made this election in order 
to avoid significant variations in the level of capital depending upon the impact of interest rate fluctuations on the 
fair value of their available-for-sale securities portfolio. Under the Basel III Capital Rules, trust preferred securities 
no  longer  included  in  our  Tier  1  capital  may  nonetheless  be  included  as  a  component  of  Tier  2  capital  on  a 
permanent basis without phase-out.

In February 2019, the federal bank regulatory agencies issued a final rule (the “2019 CECL Rule”) that revised 
certain capital regulations to account for changes to credit loss accounting under U.S. GAAP. The 2019 CECL Rule 
included  a  transition  option  that  allows  banking  organizations  to  phase  in,  over  a  three-year  period,  the  day-one 
adverse effects of adopting a new accounting standard related to the measurement of current expected credit losses 
(“CECL”) on their regulatory capital ratios (three-year transition option). In March 2020, the federal bank regulatory 
agencies issued an interim final rule that maintains the three-year transition option of the 2019 CECL Rule and also 
provides  banking  organizations  that  were  required  under  U.S.  GAAP  (as  of  January  2020)  to  implement  CECL 
before the end of 2020 the option to delay for two years an estimate of the effect of CECL on regulatory capital, 
relative  to  the  incurred  loss  methodology’s  effect  on  regulatory  capital,  followed  by  a  three-year  transition  period 
(five-year transition option). We elected to adopt the five-year transition option. Accordingly, a CECL transitional 
amount  totaling  $61.6  million  has  been  added  back  to  CET1  as  of  December  31,  2021.  The  CECL  transitional 
amount includes $29.3 million related to the cumulative effect of adopting CECL and $32.4 million related to the 
estimated incremental effect of CECL since adoption.

The  Basel  III  Capital  Rules  prescribe  a  standardized  approach  for  risk  weightings  that  expanded  the  risk-
weighting categories from the general risk-based capital rules to a much larger and more risk-sensitive number of 
categories,  depending  on  the  nature  of  the  assets,  generally  ranging  from  0%  for  U.S.  government  and  agency 
securities,  to  600%  for  certain  equity  exposures  (and  higher  percentages  for  certain  other  types  of  interests),  and 
resulting in higher risk weights for a variety of asset categories. Effective April 2020, the federal banking agencies 
adopted a rule revising the scope of commercial real estate mortgages subject to a 150% risk weight.

10

In December 2017, the Basel Committee published standards that it described as the finalization of the Basel III 
post-crisis  regulatory  reforms  (the  standards  are  commonly  referred  to  as  “Basel  IV”).  Among  other  things,  these 
standards revise the Basel Committee's standardized approach for credit risk (including by recalibrating risk weights 
and  introducing  new  capital  requirements  for  certain  “unconditionally  cancellable  commitments,”  such  as  unused 
credit card lines of credit) and provides a new standardized approach for operational risk capital. Under the Basel 
framework, these standards will generally be effective on January 1, 2023, with an aggregate output floor phasing in 
through  January  1,  2028.  Under  the  current  U.S.  capital  rules,  operational  risk  capital  requirements  and  a  capital 
floor apply only to advanced approaches institutions, and not to Cullen/Frost or Frost Bank. The impact of Basel IV 
on us will depend on the manner in which it is implemented by the federal bank regulators.

Liquidity Requirements

The  Basel  III  liquidity  framework  and  regulations  of  the  Federal  Reserve  require  that  certain  banks  and  bank 
holding  companies  measure  their  liquidity  against  specific  liquidity  tests.  One  test,  referred  to  as  the  liquidity 
coverage ratio (“LCR”), is designed to ensure that the banking entity maintains an adequate level of unencumbered 
high-quality liquid assets equal to the entity’s expected net cash outflow for a 30-day time horizon (or, if greater, 
25% of its expected total cash outflow) under an acute liquidity stress scenario. The other test, referred to as the net 
stable  funding  ratio  (“NSFR”),  is  designed  to  promote  more  medium-  and  long-term  funding  of  the  assets  and 
activities of banking entities over a one-year time horizon. Rules applicable to certain large banking organizations 
have been implemented for LCR and for NSFR; however, based on our asset size, these rules do not currently apply 
to Cullen/Frost and Frost Bank.

Prompt Corrective Action

The  Federal  Deposit  Insurance  Act,  as  amended  (“FDIA”),  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.  The  FDIA  includes  the  following  five  capital  tiers:  “well  capitalized,”  “adequately  capitalized,” 
“undercapitalized,” “significantly undercapitalized” and “critically undercapitalized.”

A bank will be (i) “well capitalized” if the institution has a total risk-based capital ratio of 10.0% or greater, a 
CET1 capital ratio of 6.5% or greater, a Tier 1 risk-based capital ratio of 8.0% or greater, and a leverage ratio of 
5.0% or greater, and is not subject to any order or written directive by any such regulatory authority to meet and 
maintain  a  specific  capital  level  for  any  capital  measure;  (ii)  “adequately  capitalized”  if  the  institution  has  a  total 
risk-based capital ratio of 8.0% or greater, a CET1 capital ratio of 4.5% or greater, a Tier 1 risk-based capital ratio of 
6.0% or greater, and a leverage ratio of 4.0% or greater and is not “well capitalized”; (iii) “undercapitalized” if the 
institution has a total risk-based capital ratio that is less than 8.0%, a CET1 capital ratio less than 4.5%, a Tier 1 risk-
based capital ratio of less than 6.0% or a leverage ratio of less than 4.0%; (iv) “significantly undercapitalized” if the 
institution has a total risk-based capital ratio of less than 6.0%, a CET1 capital ratio less than 3.0%, a Tier 1 risk-
based capital ratio of less than 4.0% or a leverage ratio of less than 3.0%; and (v) “critically undercapitalized” if the 
institution’s tangible equity is equal to or less than 2.0% of average quarterly tangible assets. An institution may be 
downgraded  to,  or  deemed  to  be  in,  a  capital  category  that  is  lower  than  indicated  by  its  capital  ratios  if  it  is 
determined to be in an unsafe or unsound condition or if it receives an unsatisfactory examination rating with respect 
to  certain  matters.  A  bank’s  capital  category  is  determined  solely  for  the  purpose  of  applying  prompt  corrective 
action  regulations,  and  the  capital  category  may  not  constitute  an  accurate  representation  of  the  bank’s  overall 
financial condition or prospects for other purposes.

The FDIA prohibits an insured depository institution from accepting brokered deposits or offering interest rates 
on  any  deposits  significantly  higher  than  the  prevailing  rate  in  the  bank’s  normal  market  area  or  nationally 
(depending  upon  where  the  deposits  are  solicited),  unless  it  is  well  capitalized  or  is  adequately  capitalized  and 
receives a waiver from the FDIC.

Additionally,  the  FDIA  generally  prohibits  a  depository  institution  from  making  any  capital  distributions 
(including payment of a dividend) or paying any management fee to its parent holding company if the depository 
institution would thereafter be “undercapitalized.” “Undercapitalized” institutions are subject to growth limitations 
and are required to submit a capital restoration plan. The agencies may not accept such a 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  depository  institution’s  parent 
holding  company  must  guarantee  that  the  institution  will  comply  with  such  capital  restoration  plan.  The  bank 

11

holding  company  must  also  provide  appropriate  assurances  of  performance.  The  aggregate  liability  of  the  parent 
holding company is limited to the lesser of (i) an amount equal to 5.0% of the depository institution’s total assets at 
the time it became undercapitalized and (ii) the amount which 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  an  acceptable  plan,  it  is  treated  as  if  it  is 
“significantly undercapitalized.”

“Significantly  undercapitalized”  depository  institutions  may  be  subject  to  a  number  of  requirements  and 
restrictions,  including  orders  to  sell  sufficient  voting  stock  to  become  “adequately  capitalized,”  requirements  to 
reduce  total  assets,  and  cessation  of  receipt  of  deposits  from  correspondent  banks.  “Critically  undercapitalized” 
institutions are subject to the appointment of a receiver or conservator.

The  appropriate  federal  banking  agency  may,  under  certain  circumstances,  reclassify  a  well  capitalized  insured 
depository  institution  as  adequately  capitalized.  The  FDIA  provides  that  an  institution  may  be  reclassified  if  the 
appropriate federal banking agency determines (after notice and opportunity for hearing) that the institution is in an 
unsafe  or  unsound  condition  or  deems  the  institution  to  be  engaging  in  an  unsafe  or  unsound  practice.  The 
appropriate agency is also permitted to require an adequately capitalized or undercapitalized institution to comply 
with  the  supervisory  provisions  as  if  the  institution  were  in  the  next  lower  category  (but  not  treat  a  significantly 
undercapitalized  institution  as  critically  undercapitalized)  based  on  supervisory  information  other  than  the  capital 
levels of the institution.

Cullen/Frost  believes  that,  as  of  December  31,  2021,  its  bank  subsidiary,  Frost  Bank,  was  “well  capitalized” 
based on the aforementioned ratios. For further information regarding the capital ratios and leverage ratio of Cullen/
Frost  and  Frost  Bank  see  the  discussion  under  the  section  captioned  “Capital  and  Liquidity”  included  in  Item  7. 
Management’s Discussion and Analysis of Financial Condition and Results of Operations and Note 9 - Capital and 
Regulatory  Matters  in  the  notes  to  consolidated  financial  statements  included  in  Item  8.  Financial  Statements  and 
Supplementary Data, elsewhere in this report.

The prompt corrective action regulations do not apply to bank holding companies. However, the Federal Reserve 
Board is authorized to take appropriate action at the bank holding company level, based upon the undercapitalized 
status of the bank holding company’s depository institution subsidiaries.

Safety and Soundness Standards

The  FDIA  requires  the  federal  bank  regulatory  agencies  to  prescribe  standards,  by  regulations  or  guidelines, 
relating  to  internal  controls,  information  systems  and  internal  audit  systems,  loan  documentation,  credit 
underwriting,  interest  rate  risk  exposure,  asset  growth,  asset  quality,  earnings,  stock  valuation  and  compensation, 
fees and benefits, and such other operational and managerial standards as the agencies deem appropriate. Guidelines 
adopted  by  the  federal  bank  regulatory  agencies  establish  general  standards  relating  to  internal  controls  and 
information  systems,  internal  audit  systems,  loan  documentation,  credit  underwriting,  interest  rate  exposure,  asset 
growth  and  compensation,  fees  and  benefits.  In  general,  the  guidelines  require,  among  other  things,  appropriate 
systems  and  practices  to  identify  and  manage  the  risk  and  exposures  specified  in  the  guidelines.  The  guidelines 
prohibit excessive compensation as an unsafe and unsound practice and describe compensation as excessive when 
the amounts paid are unreasonable or disproportionate to the services performed by an executive officer, employee, 
director or principal stockholder. In addition, the agencies adopted regulations that authorize, but do not require, an 
agency to order an institution that has been given notice by an agency that it is not satisfying any of such safety and 
soundness  standards  to  submit  a  compliance  plan.  If,  after  being  so  notified,  an  institution  fails  to  submit  an 
acceptable compliance plan or fails in any material respect to implement an acceptable compliance plan, the agency 
must issue an order directing action to correct the deficiency and may issue an order directing other actions of the 
types  to  which  an  undercapitalized  institution  is  subject  under  the  “prompt  corrective  action”  provisions  of  the 
FDIA. See “Prompt Corrective Action” above. If an institution fails to comply with such an order, the agency may 
seek to enforce such order in judicial proceedings and to impose civil money penalties.

Deposit Insurance

Deposits at Frost Bank are insured up to applicable limits by the Deposit Insurance Fund (“DIF”) of the FDIC and 
Frost Bank is subject to deposit insurance assessments to maintain the DIF. Deposit insurance assessments are based 
on average total assets minus average tangible equity. For larger institutions, such as Frost Bank, the FDIC uses a 
performance score and a loss-severity score that are used to calculate an initial assessment rate. In calculating these 

12

scores,  the  FDIC  uses  a  bank’s  capital  level  and  supervisory  ratings  and  certain  financial  measures  to  assess  an 
institution’s  ability  to  withstand  asset-related  stress  and  funding-related  stress.  The  FDIC  has  the  ability  to  make 
discretionary adjustments to the total score based upon significant risk factors that are not adequately captured in the 
calculations.

Under  the  FDIA,  the  FDIC  may  terminate  deposit  insurance  upon  a  finding  that  the  institution  has  engaged  in 
unsafe  and  unsound  practices,  is  in  an  unsafe  or  unsound  condition  to  continue  operations,  or  has  violated  any 
applicable  law,  regulation,  rule,  order  or  condition  imposed  by  the  FDIC.  In  addition,  the  FDIC  is  authorized  to 
conduct examinations of and require reporting by FDIC-insured institutions.

Enhanced Prudential Standards 

The  Federal  Reserve  Board  is  required  to  monitor  emerging  risks  to  financial  stability  and  enact  enhanced 
supervision  and  prudential  standards  applicable  to  large  bank  holding  companies  and  certain  non-bank  covered 
companies designated as systemically important by the Financial Stability Oversight Council. The Dodd-Frank Wall 
Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) mandates that certain regulatory requirements 
applicable  to  these  systemically  important  financial  institutions  be  more  stringent  than  those  applicable  to  other 
financial institutions. In 2019, the Federal Reserve Board adopted new rules impacting certain capital and liquidity 
requirements and other enhanced prudential standards. The final rules assign all domestic bank holding companies 
with $100 billion or more in total consolidated assets to one of four categories of tailored regulatory requirements. 
Cullen/Frost and Frost Bank are generally not impacted by these rules. The enhanced prudential standards rules, as 
amended  in  2019,  require  publicly  traded  bank  holding  companies  with  $50  billion  or  more  in  total  consolidated 
assets  to  establish  risk  committees.  Prior  to  the  amendment,  the  requirement  to  establish  a  risk  committee  was 
applicable to publicly traded bank holding companies with $10 billion or more in consolidated assets. Cullen/Frost 
has established and currently maintains a risk committee.

The Volcker Rule

The  so-called  Volcker  Rule  under  the  Dodd-Frank  Act  restricts  banks  and  their  affiliates  from  engaging  in 
proprietary trading and investing in and sponsoring hedge funds and private equity funds. The Volcker Rule does not 
significantly  impact  the  operations  of  Cullen/Frost  and  its  subsidiaries  as  we  do  not  have  any  engagement  in  the 
businesses prohibited by the Volcker Rule.

Depositor Preference

The FDIA provides that, in the event of the “liquidation or other resolution” of an insured depository institution, 
the claims of depositors of the institution, including the claims of the FDIC as subrogee of insured depositors, and 
certain claims for administrative expenses of the FDIC as a receiver, will have priority over other general unsecured 
claims against the institution. If an insured depository institution fails, insured and uninsured depositors, along with 
the  FDIC,  will  have  priority  in  payment  ahead  of  unsecured,  non-deposit  creditors,  including  depositors  whose 
deposits  are  payable  only  outside  of  the  United  States  and  the  parent  bank  holding  company,  with  respect  to  any 
extensions of credit they have made to such insured depository institution.

Interchange Fees

Under the Durbin Amendment to the Dodd-Frank Act, the Federal Reserve adopted rules establishing standards 
for assessing whether the interchange fees that may be charged with respect to certain electronic debit transactions 
are “reasonable and proportional” to the costs incurred by issuers for processing such transactions.

Interchange  fees,  or  “swipe”  fees,  are  charges  that  merchants  pay  to  us  and  other  card-issuing  banks  for 
processing electronic payment transactions. Federal Reserve Board rules applicable to financial institutions that have 
assets  of  $10  billion  or  more  provide  that  the  maximum  permissible  interchange  fee  for  an  electronic  debit 
transaction is the sum of 21 cents per transaction and 5 basis points multiplied by the value of the transaction. An 
upward  adjustment  of  no  more  than  1  cent  to  an  issuer's  debit  card  interchange  fee  is  allowed  if  the  card  issuer 
develops and implements policies and procedures reasonably designed to achieve certain fraud-prevention standards. 
The  Federal  Reserve  Board  also  has  rules  governing  routing  and  exclusivity  that  require  issuers  to  offer  two 
unaffiliated networks for routing transactions on each debit or prepaid product.

Consumer Financial Protection

We are subject to a number of federal and state consumer protection laws that extensively govern our relationship 
with our customers. These laws include the Equal Credit Opportunity Act, the Fair Credit Reporting Act, the Truth 
in Lending Act, the Truth in Savings Act, the Electronic Fund Transfer Act, the Expedited Funds Availability Act, 
the Home Mortgage Disclosure Act, the Fair Housing Act, the Real Estate Settlement Procedures Act, the Fair Debt 
Collection Practices Act, the Service Members Civil Relief Act and these laws’ respective state-law counterparts, as 
well as state usury laws and laws regarding unfair and deceptive acts and practices. These and other federal laws, 
among  other  things,  require  disclosures  of  the  cost  of  credit  and  terms  of  deposit  accounts,  provide  substantive 
consumer rights, prohibit discrimination in credit transactions, regulate the use of credit report information, provide 
financial  privacy  protections,  prohibit  unfair,  deceptive  and  abusive  practices,  restrict  our  ability  to  raise  interest 
rates and subject us to substantial regulatory oversight. Violations of applicable consumer protection laws can result 
in  significant  potential  liability  from  litigation  brought  by  customers,  including  actual  damages,  restitution  and 
attorneys’  fees.  Federal  bank  regulators,  state  attorneys  general  and  state  and  local  consumer  protection  agencies 
may  also  seek  to  enforce  consumer  protection  requirements  and  obtain  these  and  other  remedies,  including 
regulatory sanctions, customer rescission rights, action by the state and local attorneys general in each jurisdiction in 
which  we  operate  and  civil  money  penalties.  Failure  to  comply  with  consumer  protection  requirements  may  also 
result in our failure to obtain any required bank regulatory approval for merger or acquisition transactions we may 
wish to pursue or our prohibition from engaging in such transactions even if approval is not required.

The  Consumer  Financial  Protection  Bureau  (“CFPB”)  is  a  federal  agency  responsible  for  implementing, 
examining  and  enforcing  compliance  with  federal  consumer  protection  laws.  The  CFPB  has  broad  rulemaking 
authority for a wide range of consumer financial laws that apply to all banks, including, among other things, laws 
relating to fair lending and the authority to prohibit “unfair, deceptive or abusive” acts and practices. Abusive acts or 
practices are defined as those that materially interfere with a consumer’s ability to understand a term or condition of 
a consumer financial product or service or take unreasonable advantage of a consumer’s (i) lack of financial savvy, 
(ii) inability to protect himself in the selection or use of consumer financial products or services, or (iii) reasonable 
reliance on a covered entity to act in the consumer’s interests. The CFPB can issue cease-and-desist orders against 
banks and other entities that violate consumer financial laws. The CFPB may also institute a civil action against an 
entity in violation of federal consumer financial law in order to impose a civil penalty or injunction. The CFPB has 
examination and enforcement authority over all banks with more than $10 billion in assets, as well as their affiliates. 
Banking  regulators  take  into  account  compliance  with  consumer  protection  laws  when  considering  approval  of  a 
proposed transaction.

Community Reinvestment Act

The  Community  Reinvestment  Act  of  1977  (“CRA”)  requires  depository  institutions  to  assist  in  meeting  the 
credit needs of their market areas consistent with safe and sound banking practice. Under the CRA, each depository 
institution is required to help meet the credit needs of its market areas by, among other things, providing credit to 
low-  and  moderate-income  individuals  and  communities.  Depository  institutions  are  periodically  examined  for 
compliance with the CRA and are assigned ratings. In order for a financial holding company to commence any new 
activity permitted by the BHC Act, or to acquire any company engaged in any new activity permitted by the BHC 
Act, each insured depository institution subsidiary of the financial holding company must have received a rating of 
at  least  “satisfactory”  in  its  most  recent  examination  under  the  CRA.  Furthermore,  banking  regulators  take  into 
account CRA ratings when considering a request for an approval of a proposed transaction. Frost Bank received a 
rating of “satisfactory” in its most recent CRA examination.

In December 2019, the Federal Deposit Insurance Corporation (“FDIC”) and the Office of the Comptroller of the 
Currency (“OCC”) jointly proposed rules that would significantly change existing CRA regulations. The proposed 
rules  are  intended  to  increase  bank  activity  in  low-  and  moderate-income  communities  where  there  is  significant 
need  for  credit,  more  responsible  lending,  greater  access  to  banking  services,  and  improvements  to  critical 
infrastructure.  The  proposals  change  four  key  areas:  (i)  clarifying  what  activities  qualify  for  CRA  credit;  (ii) 
updating  where  activities  count  for  CRA  credit;  (iii)  providing  a  more  transparent  and  objective  method  for 
measuring  CRA  performance;  and  (iv)  revising  CRA-related  data  collection,  record  keeping,  and  reporting. 
However,  the  Federal  Reserve  Board  did  not  join  in  that  proposed  rulemaking.  In  June  2020,  the  OCC  issued  its 
final  CRA  rule,  effective  October  1,  2020,  while  the  FDIC  did  not  finalize  any  revisions  to  its  CRA  rule.  In 
September  2020,  the  Federal  Reserve  Board  issued  an  Advance  Notice  of  Proposed  Rulemaking  (“ANPR”)  that 

14

invited  public  comment  on  an  approach  to  modernize  the  regulations  that  implement  the  CRA  by  strengthening, 
clarifying, and tailoring them to reflect the current banking landscape and better meet the core purpose of the CRA. 

The  ANPR  sought  feedback  on  ways  to  evaluate  how  banks  meet  the  needs  of  low-  and  moderate-income 
communities and address inequities in credit access. In December 2021, the OCC issued a final rule to rescind its 
June 2020 final rule in favor of working with other agencies to put forward a joint rule. We will continue to evaluate 
the  impact  of  any  changes  to  the  regulations  implementing  the  CRA  and  their  impact  to  our  financial  condition, 
results of operations, and/or liquidity, which cannot be predicted at this time.

Financial Privacy

The  federal  banking  regulators  adopted  rules  that  limit  the  ability  of  banks  and  other  financial  institutions  to 
disclose non-public information about consumers to nonaffiliated third parties. These limitations require disclosure 
of  privacy  policies  to  consumers  and,  in  some  circumstances,  allow  consumers  to  prevent  disclosure  of  certain 
personal information to a nonaffiliated third party. These regulations affect how consumer information is transmitted 
through diversified financial companies and conveyed to outside vendors.

Anti-Money Laundering and the USA Patriot Act

A  major  focus  of  governmental  policy  on  financial  institutions  in  recent  years  has  been  aimed  at  combating 
money laundering and terrorist financing. The USA PATRIOT Act of 2001, or the USA Patriot Act, substantially 
broadened  the  scope  of  United  States  anti-money  laundering  laws  and  regulations  by  imposing  significant  new 
compliance  and  due  diligence  obligations,  creating  new  crimes  and  penalties  and  expanding  the  extra-territorial 
jurisdiction  of  the  United  States.  Financial  institutions  are  also  prohibited  from  entering  into  specified  financial 
transactions and account relationships and must use enhanced due diligence procedures in their dealings with certain 
types of high-risk customers and implement a written customer identification program. Financial institutions must 
take  certain  steps  to  assist  government  agencies  in  detecting  and  preventing  money  laundering  and  report  certain 
types of suspicious transactions. Regulatory authorities routinely examine financial institutions for compliance with 
these  obligations,  and  failure  of  a  financial  institution  to  maintain  and  implement  adequate  programs  to  combat 
money  laundering  and  terrorist  financing,  or  to  comply  with  all  of  the  relevant  laws  or  regulations,  could  have 
serious  financial,  legal  and  reputational  consequences  for  the  institution,  including  causing  applicable  bank 
regulatory authorities not to approve merger or acquisition transactions when regulatory approval is required or to 
prohibit  such  transactions  even  if  approval  is  not  required.  Regulatory  authorities  have  imposed  cease  and  desist 
orders and civil money penalties against institutions found to be violating these obligations.

The  Anti-Money  Laundering  Act  of  2020  (“AMLA”),  which  amends  the  Bank  Secrecy  Act  of  1970  (“BSA”), 
was enacted in January 2021. The AMLA is intended to be a comprehensive reform and modernization to U.S. bank 
secrecy  and  anti-money  laundering  laws.  Among  other  things,  it  codifies  a  risk-based  approach  to  anti-money 
laundering  compliance  for  financial  institutions;  requires  the  U.S.  Department  of  the  Treasury  to  promulgate 
priorities for anti-money laundering and countering the financing of terrorism policy; requires  the development of 
standards  for  testing  technology  and  internal  processes  for  BSA  compliance;  expands  enforcement-  and 
investigation-related  authority,  including  increasing  available  sanctions  for  certain  BSA  violations;  and  expands 
BSA  whistleblower  incentives  and  protections.  Many  of  the  statutory  provisions  in  the  AMLA  will  require 
additional  rulemakings,  reports  and  other  measures,  and  the  impact  of  the  AMLA  will  depend  on,  among  other 
things,  rulemaking  and  implementation  guidance.  In  June  2021,  the  Financial  Crimes  Enforcement  Network,  a 
bureau of the U.S. Department of the Treasury, issued the priorities for anti-money laundering and countering the 
financing  of  terrorism  policy  required  under  the  AMLA.  The  priorities  include:  corruption,  cybercrime,  terrorist 
financing, fraud, transnational crime, drug trafficking, human trafficking and proliferation financing.

Office of Foreign Assets Control Regulation

The U.S. Treasury Department’s Office of Foreign Assets Control, or OFAC, administers and enforces economic 
and  trade  sanctions  against  targeted  foreign  countries  and  regimes,  under  authority  of  various  laws,  including 
designated  foreign  countries,  nationals  and  others.  OFAC  publishes  lists  of  specially  designated  targets  and 
countries. We are responsible for, among other things, blocking accounts of, and transactions with, such targets and 
countries, prohibiting unlicensed trade and financial transactions with them and reporting blocked transactions after 
their  occurrence.  Failure  to  comply  with  these  sanctions  could  have  serious  financial,  legal  and  reputational 
consequences,  including  causing  applicable  bank  regulatory  authorities  not  to  approve  merger  or  acquisition 
transactions when regulatory approval is required or to prohibit such transactions even if approval is not required.

Regulatory authorities have imposed cease and desist orders and civil money penalties against institutions found to 
be violating these obligations.

Incentive Compensation

The  Federal  Reserve  Board  reviews,  as  part  of  its  regular,  risk-focused  examination  process,  the  incentive 
compensation  arrangements  of  banking  organizations,  such  as  Cullen/Frost,  that  are  not  “large,  complex  banking 
organizations.”  These  reviews  are  tailored  to  each  organization  based  on  the  scope  and  complexity  of  the 
organization’s  activities  and  the  prevalence  of  incentive  compensation  arrangements.  Deficiencies  will  be 
incorporated  into  the  organization’s  supervisory  ratings,  which  can  affect  the  organization’s  ability  to  make 
acquisitions and take other actions. 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 and the organization is not taking prompt and effective measures to correct the 
deficiencies.

In  June  2010,  the  Federal  Reserve  Board,  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  all  employees  that  have  the  ability  to  materially  affect  the  risk  profile  of  an  organization,  either 
individually  or  as  part  of  a  group,  is  based  upon  the  key  principles  that  a  banking  organization’s  incentive 
compensation  arrangements  should  (i)  provide  incentives  that  do  not  encourage  risk-taking  beyond  the 
organization’s ability to effectively identify and manage risks, (ii) be compatible with effective internal controls and 
risk management, and (iii) be supported by strong corporate governance, including active and effective oversight by 
the organization’s board of directors.

In 2016, the U.S. financial regulators, including the Federal Reserve Board and the SEC, proposed revised rules 
on  incentive-based  payment  arrangements  at  specified  regulated  entities  having  at  least  $1  billion  in  total  assets 
(including Cullen/Frost and Frost Bank), but these proposed rules have not been finalized. 

Cybersecurity

In  February  2018,  the  SEC  published  interpretive  guidance  to  assist  public  companies  in  preparing  disclosures 
about cybersecurity risks and incidents. These SEC guidelines, and any other regulatory guidance, are in addition to 
notification and disclosure requirements under state and federal banking law and regulations.

The  federal  banking  regulators  regularly  issue  new  guidance  and  standards,  and  update  existing  guidance  and 
standards,  regarding  cybersecurity  intended  to  enhance  cyber  risk  management  among  financial  institutions.  
Financial  institutions  are  expected  to  comply  with  such  guidance  and  standards  and  to  accordingly  develop 
appropriate  security  controls  and  risk  management  processes.  If  we  fail  to  observe  such  regulatory  guidance  or 
standards, we could be subject to various regulatory sanctions, including financial penalties.

Recently,  in  November  2021,  the  federal  banking  agencies  adopted  a  Final  Rule,  with  compliance  required  by 
May  1,  2022,  that  requires  banking  organizations  to  notify  their  primary  banking  regulator  within  36  hours  of 
determining  that  a  “computer-security  incident”  has  materially  disrupted  or  degraded,  or  is  reasonably  likely  to 
materially disrupt or degrade, the banking organization’s ability to carry out banking operations or deliver banking 
products and services to a material portion of its customer base, its businesses and operations that would result in 
material loss, or its operations that would impact the stability of the United States.

State  regulators  have  also  been  increasingly  active  in  implementing  privacy  and  cybersecurity  standards  and 
regulations.  Recently,  several  states  have  adopted  regulations  requiring  certain  financial  institutions  to  implement 
cybersecurity  programs  and  many  states,  including  Texas,  have  also  recently  implemented  or  modified  their  data 
breach notification, information security and data privacy requirements. We expect this trend of state-level activity 
in  those  areas  to  continue,  and  are  continually  monitoring  developments  in  the  states  in  which  our  customers  are 
located.

Risks and exposures related to cybersecurity attacks, including litigation and enforcement risks, are expected to 
be elevated for the foreseeable future due to the rapidly evolving nature and sophistication of these threats, as well as 
due to the expanding use of Internet banking, mobile banking and other technology-based products and services by 
us and our customers. 

See Item 1A. Risk Factors for a further discussion of risks related to cybersecurity.

Future Legislation and Regulation

Congress may enact legislation from time to time that affects the regulation of the financial services industry, and 
state legislatures may enact legislation from time to time affecting the regulation of financial institutions chartered 
by or operating in those states. Federal and state regulatory agencies also periodically propose and adopt changes to 
their regulations or change the manner in which existing regulations are applied. The substance or impact of pending 
or future legislation or regulation, or the application thereof, cannot be predicted, although any change could impact 
the regulatory structure under which we or our competitors operate and may significantly increase costs, impede the 
efficiency  of  internal  business  processes,  require  an  increase  in  regulatory  capital,  require  modifications  to  our 
business strategy, and limit our ability to pursue business opportunities in an efficient manner. It could also affect 
our  competitors  differently  than  us,  including  in  a  manner  that  would  make  them  more  competitive.  A  change  in 
statutes, regulations or regulatory policies applicable to Cullen/Frost or any of its subsidiaries could have a material, 
adverse effect on our business, financial condition and results of operations.

Human Capital Resources

At December 31, 2021, we employed 4,553 full-time equivalent employees. At that date, the average tenure of all 
of  our  full-time  employees  was  approximately  10.7  years  while  the  average  tenure  of  our  executive  officers  was 
approximately 32.2 years. None of our employees are represented by collective bargaining agreements. We believe 
our employee relations to be good.

Oversight of our corporate culture is an important element of our board of director’s oversight of risk because our 
people  are  critical  to  the  success  of  our  corporate  strategy.  Our  board  sets  the  “tone  at  the  top,”  and  holds  senior 
management accountable for embodying, maintaining, and communicating our culture to employees. In that regard, 
our  culture  is  designed  to  promote  commitment  to  making  people's  lives  better  and  to  uphold  that  principle  in 
everything we do. That commitment has been a central pillar in our approach to our employees, our planet and the 
communities we have proudly served for over 150 years. Our culture is designed to adhere to the timeless values of 
integrity,  caring  and  excellence.  In  keeping  with  that  culture,  we  expect  our  people  to  treat  each  other  and  our 
customers with the highest level of honesty and respect and go out of their way to do the right thing, and we strive to 
be  a  force  for  good  in  everyday  life.  We  dedicate  resources  to  promote  a  safe  and  inclusive  workplace;  attract, 
develop  and  retain  talented,  diverse  employees;  promote  a  culture  of  integrity,  caring  and  excellence;  and  reward 
and recognize employees for both the results they deliver and, importantly, how they deliver them. We also seek to 
design  careers  that  are  fulfilling  ones,  with  competitive  compensation  and  benefits  alongside  a  positive  work-life 
balance.  We  also  dedicate  resources  to  fostering  professional  and  personal  growth  with  continuing  education,  on-
the-job training and development programs. This devotion to our people has earned us a spot on Forbes magazine's 
Best Employers list. 

Our  employees  are  key  to  our  success  as  an  organization.  We  are  committed  to  attracting,  retaining  and 
promoting top quality talent regardless of sex, sexual orientation, gender identity, race, color, national origin, age, 
religion  and  physical  ability.  We  strive  to  identify  and  select  the  best  candidates  for  all  open  positions  based  on 
qualifying  factors  for  each  job.  We  are  dedicated  to  providing  a  workplace  for  our  employees  that  is  inclusive, 
supportive, and free of any form of discrimination or harassment; rewarding and recognizing our employees based 
on  their  individual  results  and  performance  as  well  as  that  of  their  department  and  the  company  overall;  and 
recognizing and respecting all of the characteristics and differences that make each of our employees unique.

We believe employing a diverse workforce enhances our ability to serve our customers and our communities. By 
promoting  and  fostering  a  workforce  that  we  believe  is  reflective  of  our  customers  and  communities,  we  seek  to 
better  understand  the  financial  needs  of  our  prospects  and  customers  and  provide  them  with  relevant  financial 
service  products.  Understanding  and  supporting  our  community  has  always  been  a  priority  to  us.  We  have 
established  a  voluntary,  employee-led  and  staffed  team  that  is  committed  to  touching  and  improving  the  lives  of 
people that live and work in our community. Additionally, we provide employees the opportunity to use paid time 
off to perform community service activities in their choice of ways. In 2021, this amounted to nearly 9,000 hours of 
community service performed by our employees. Our efforts are designed to enrich the lives of not only those that 
are in need but also the lives of our employees who participate in these meaningful and rewarding opportunities.

We believe embracing and understanding diversity has and will continue to make us a stronger company. We also 
believe that our diverse workforce is representative of our customers in the community and enables us to better serve 
our  customers,  enhancing  our  success  as  an  organization.  As  we  move  forward,  we  will  continue  to  embrace 
diversity and approach it in a manner consistent with our philosophy, by focusing on our employees, our customers, 
and our community.

ITEM 1A. RISK FACTORS

An  investment  in  our  common  stock  is  subject  to  risks  inherent  to  our  business.  The  material  risks  and 
uncertainties that management believes affect us are described below. Before making an investment decision, you 
should  carefully  consider  the  risks  and  uncertainties  described  below  together  with  all  of  the  other  information 
included  or  incorporated  by  reference  in  this  report.  The  risks  and  uncertainties  described  below  are  not  the  only 
ones  facing  us.  Additional  risks  and  uncertainties  that  management  is  not  aware  of  or  focused  on  or  that 
management  currently  deems  immaterial  may  also  impair  our  business  operations.  This  report  is  qualified  in  its 
entirety  by  these  risk  factors.  If  any  of  the  following  risks  actually  occur,  our  business,  financial  condition  and 
results  of  operations  could  be  materially  and  adversely  affected.  If  this  were  to  happen,  the  market  price  of  our 
common stock could decline significantly, and you could lose all or part of your investment.

Risks Related To Our Business

Interest Rate Risks

We Are Subject To Interest Rate Risk

Our  earnings  and  cash  flows  are  largely  dependent  upon  our  net  interest  income.  Net  interest  income  is  the 
difference  between  interest  income  earned  on  interest-earning  assets  such  as  loans  and  securities  and  interest 
expense paid on interest-bearing liabilities such as deposits and borrowed funds. Interest rates are highly sensitive to 
many  factors  that  are  beyond  our  control,  including  general  economic  conditions,  inflationary  trends,  changes  in 
government  spending  and  debt  issuances  and  policies  of  various  governmental  and  regulatory  agencies  and,  in 
particular,  the  Federal  Open  Market  Committee.  Changes  in  monetary  policy,  including  changes  in  interest  rates, 
could  influence  not  only  the  interest  we  receive  on  loans  and  securities  and  the  amount  of  interest  we  pay  on 
deposits  and  borrowings,  but  such  changes  could  also  affect  (i)  our  ability  to  originate  loans  and  obtain  deposits, 
(ii)  the  fair  value  of  our  financial  assets  and  liabilities,  and  (iii)  the  average  duration  of  our  mortgage-backed 
securities  portfolio.  If  the  interest  rates  paid  on  deposits  and  other  borrowings  increase  at  a  faster  rate  than  the 
interest  rates  received  on  loans  and  other  investments,  our  net  interest  income,  and  therefore  earnings,  could  be 
adversely  affected.  Earnings  could  also  be  adversely  affected  if  the  interest  rates  received  on  loans  and  other 
investments  fall  more  quickly  than  the  interest  rates  paid  on  deposits  and  other  borrowings.  Some  foreign  central 
banks have moved to a negative interest rate environment, which has exerted downward pressure on the profitability 
of banks in those regions and this interest rate trend could extend to the United States. Any substantial, unexpected, 
or prolonged change in market interest rates could have a material adverse effect on our business, financial condition 
and results of operations. See Item 7. Management’s Discussion and Analysis of Financial Condition and Results of 
Operations under the section captioned “Net Interest Income” and Item 7A. Quantitative and Qualitative Disclosures 
About  Market  Risk  elsewhere  in  this  report  for  further  discussion  related  to  interest  rate  sensitivity  and  our 
management of interest rate risk.

19

We May Be Adversely Impacted By The Transition From LIBOR As A Reference Rate

The  United  Kingdom’s  Financial  Conduct  Authority  and  the  administrator  of  LIBOR  have  announced  that  the 
publication of the most commonly used U.S. dollar London Interbank Offered Rate (“LIBOR”) settings will cease to 
be published or cease to be representative after June 30, 2023. The publication of all other LIBOR settings ceased to 
be  published  as  of  December  31,  2021.  Given  consumer  protection,  litigation,  and  reputation  risks,  the  bank 
regulatory  agencies  have  indicated  that  entering  into  new  contracts  that  use  LIBOR  as  a  reference  rate  after 
December 31, 2021, would create safety and soundness risks and that they will examine bank practices accordingly. 
Therefore, the agencies encouraged banks to cease entering into new contracts that use LIBOR as a reference rate as 
soon  as  practicable  and  in  any  event  by  December  31,  2021.  We  discontinued  originating  LIBOR-based  loans 
effective  December  31,  2021  and  will  negotiate  loans  using  our  preferred  replacement  index,  AMERIBOR,  a 
benchmark  developed  by  the  American  Financial  Exchange;  the  Secured  Overnight  Financing  Rate  (“SOFR”);  or 
BSBY, a benchmark developed by Bloomberg Index Services.

As of December 31, 2021, approximately $3.9 billion of our outstanding loans, and, in addition, certain derivative 
contracts, borrowings and other financial instruments have attributes that are either directly or indirectly dependent 
on  LIBOR.  The  transition  from  LIBOR  has  resulted  in  and  could  continue  to  result  in  added  costs  and  employee 
efforts  and  could  present  additional  risk.  We  are  subject  to  litigation  and  reputational  risks  if  we  are  unable  to 
renegotiate and amend existing contracts with counterparties that are dependent on LIBOR, including contracts that 
do  not  have  fallback  language.  The  timing  and  manner  in  which  each  customer’s  contract  transitions  to 
AMERIBOR, SOFR or BSBY will vary on a case-by-case basis. There continues to be substantial uncertainty as to 
the  ultimate  effects  of  the  LIBOR  transition,  including  with  respect  to  the  acceptance  and  use  of  AMERIBOR, 
SOFR,  BSBY  and  other  benchmark  rates.  Since  AMERIBOR,  SOFR  and  BSBY  rates  are  calculated  differently, 
payments  under  contracts  referencing  new  rates  will  differ  from  those  referencing  LIBOR,  which  may  lead  to 
increased  volatility  as  compared  to  LIBOR.  The  transition  has  impacted  our  market  risk  profiles  and  required 
changes to our risk and pricing models, valuation tools, product design and hedging strategies. Furthermore, failure 
to adequately manage this transition process with our customers could adversely impact our reputation. Although we 
are currently unable to assess what the ultimate impact of the transition from LIBOR will be, failure to adequately 
manage  the  transition  could  have  a  material  adverse  effect  on  our  business,  financial  condition  and  results  of 
operations.

Credit and Lending Risks

We Are Subject To Lending Risk and Lending Concentration Risk

There are inherent risks associated with our lending activities. These risks include, among other things, the impact 
of changes in interest rates and changes in the economic conditions in the markets where we operate as well as those 
across the State of Texas and the United States. Increases in interest rates and/or weakening economic conditions 
could  adversely  impact  the  ability  of  borrowers  to  repay  outstanding  loans  or  the  value  of  the  collateral  securing 
these loans.

As  of  December  31,  2021,  approximately  85.8%  of  our  loan  portfolio  consisted  of  commercial  and  industrial, 
energy, construction and commercial real estate mortgage loans. These types of loans are generally viewed as having 
more risk of default and are typically larger than residential real estate loans or consumer loans. Because our loan 
portfolio  contains  a  significant  number  of  commercial  and  industrial,  energy,  construction  and  commercial  real 
estate loans with relatively large balances, the deterioration of one or a few of these loans could cause a significant 
increase  in  non-performing  loans.  Increases  in  non-performing  loans  have  resulted  in  a  net  loss  of  earnings  from 
particular loans, an increase in credit loss expense and an increase in loan charge-offs, and these and future instances 
could  have  a  material  adverse  effect  on  our  business,  financial  condition  and  results  of  operations.  Certain  of  our 
credit  exposures  are  concentrated  in  industries  that  may  be  more  susceptible  to  the  long-term  risks  of  climate 
change,  natural  disasters  or  global  pandemics.  To  the  extent  that  these  risks  may  have  a  negative  impact  on  the 
financial condition of borrowers, it could also have a material adverse effect on our business, financial condition and 
results  of  operations.    See  the  section  captioned  “Loans”  in  Item  7.  Management’s  Discussion  and  Analysis  of 
Financial Condition and Results of Operations elsewhere in this report for further discussion related to commercial 
and industrial, energy, construction and commercial real estate loans. 

20

Our Allowance For Credit Losses May Be Insufficient

We maintain allowances for credit losses on loans, securities and off-balance sheet credit exposures. In the case 
of loans and securities, allowances for credit losses are contra-asset valuation accounts that are deducted from the 
amortized cost basis of these assets to present the net amount expected to be collected. In the case of off-balance-
sheet  credit  exposures,  the  allowance  for  credit  losses  is  a  liability  account  reported  as  a  component  of  accrued 
interest  payable  and  other  liabilities  in  our  consolidated  balance  sheets.  The  amount  of  each  allowance  account 
represents management's best estimate of current expected credit losses on these financial instruments considering 
available  information,  from  internal  and  external  sources,  relevant  to  assessing  exposure  to  credit  loss  over  the 
contractual term of the instrument. Relevant available information includes historical credit loss experience, current 
conditions  and  reasonable  and  supportable  forecasts.  As  a  result,  the  determination  of  the  appropriate  level  of 
allowance  for  credit  losses  inherently  involves  a  high  degree  of  subjectivity  and  requires  us  to  make  significant 
estimates related to current and expected future credit risks and trends, all of which may undergo material changes. 
Continuing  deterioration  in  economic  conditions  affecting  borrowers  and  securities  issuers;  new  information 
regarding existing loans, credit commitments and securities holdings; the continuation of the COVID-19 pandemic 
or  other  global  pandemics;  natural  disasters  and  risks  related  to  climate  change;  and  identification  of  additional 
problem  loans,  ratings  down-grades  and  other  factors,  both  within  and  outside  of  our  control,  may  require  an 
increase in the allowances for credit losses on loans, securities and off-balance sheet credit exposures. In addition, 
bank regulatory agencies periodically review our allowance for credit losses and may require an increase in credit 
loss expense or the recognition of further loan charge-offs, based on judgments different than those of management. 
Furthermore,  if  any  charge-offs  related  to  loans,  securities  or  off-balance  sheet  credit  exposures  in  future  periods 
exceed  our  allowances  for  credit  losses  on  loans,  securities  or  off-balance  sheet  credit  exposures,  we  will  need  to 
recognize  additional  credit  loss  expense  to  increase  the  applicable  allowance.  Any  increase  in  the  allowance  for 
credit losses on loans, securities and/or off-balance sheet credit exposures will result in a decrease in net income and, 
possibly,  capital,  and  may  have  a  material  adverse  effect  on  our  business,  financial  condition  and  results  of 
operations.  See  the  section  captioned  “Allowance  for  Credit  Losses”  in  Item  7.  Management’s  Discussion  and 
Analysis of Financial Condition and Results of Operations elsewhere in this report for further discussion related to 
our process for determining the appropriate level of the allowance for credit losses.

We Are Subject to Risk Arising From Conditions In The Commercial Real Estate Market

As  of  December  31,  2021,  commercial  real  estate  mortgage  loans  comprised  approximately  35.9%  of  our  loan 
portfolio.  Commercial  real  estate  mortgage  loans  generally  involve  a  greater  degree  of  credit  risk  than  residential 
real estate mortgage loans because they typically have larger balances and are more affected by adverse conditions 
in  the  economy.  Because  payments  on  loans  secured  by  commercial  real  estate  often  depend  upon  the  successful 
operation and management of the properties and the businesses which operate from within them, repayment of such 
loans may be affected by factors outside the borrower’s control, such as adverse conditions in the real estate market 
or  the  economy  or  changes  in  government  regulations.  In  recent  years,  commercial  real  estate  markets  have  been 
experiencing  substantial  growth,  and  increased  competitive  pressures  have  contributed  significantly  to  historically 
low  capitalization  rates  and  rising  property  values.  Furthermore,  commercial  real  estate  markets  have  been 
particularly  impacted  by  the  economic  disruption  resulting  from  the  COVID-19  pandemic.  The  COVID-19 
pandemic has also been a catalyst for the evolution of various remote work options which could impact the long-
term performance of some types of office properties within our commercial real estate portfolio. Accordingly, the 
federal banking regulatory agencies have expressed concerns about weaknesses in the current commercial real estate 
market.  Failures  in  our  risk  management  policies,  procedures  and  controls  could  adversely  affect  our  ability  to 
manage this portfolio going forward and could result in an increased rate of delinquencies in, and increased losses 
from,  this  portfolio,  which,  accordingly,  could  have  a  material  adverse  effect  on  our  business,  financial  condition 
and results of operations.

We Are Subject To Volatility Risk In Crude Oil Prices

As of December 31, 2021, we had $1.1 billion of energy loans which comprised approximately 6.6% (or 6.8% 
excluding Paycheck Protection Program loans) of our loan portfolio at that date. Furthermore, energy production and 
related industries represent a large part of the economies in some of our primary markets. Actions by members of the 
Organization of Petroleum Exporting Countries (“OPEC”) can impact global crude oil production levels and lead to 
significant  volatility  in  global  oil  supplies  and  market  oil  prices.  In  recent  years,  decreased  market  oil  prices 
compressed  margins  for  many  U.S.  and  Texas-based  oil  producers,  particularly  those  that  utilize  higher-cost 
production  technologies  such  as  hydraulic  fracking  and  horizontal  drilling,  as  well  as  oilfield  service  providers, 

21

energy  equipment  manufacturers  and  transportation  suppliers,  among  others.  In  March  of  2020,  disagreements 
between members of OPEC signaled that production levels would rise and, when coupled with the uncertainties of 
the COVID-19 pandemic, led to a significant decline in market oil prices. Oil prices have since recovered from those 
lows. The price per barrel of crude oil was approximately $75 at December 31, 2021 up from $48 at December 31, 
2020. We have experienced increased losses within our energy portfolio in recent years which were impacted by oil 
price  volatility,  relative  to  our  historical  experience.  Continued  oil  price  volatility  could  have  further  negative 
impacts  on  the  U.S.  economy,  in  particular,  the  economies  of  energy-dominant  states  such  as  Texas,  and  our 
borrowers and customers.

We Are Subject To Environmental Liability Risk Associated With Lending Activities

A significant portion of our loan portfolio is secured by real property. During the ordinary course of business, we 
foreclose on and take title to properties securing certain loans. In doing so, there is a risk that hazardous or toxic 
substances  could  be  found  on  these  properties.  If  hazardous  or  toxic  substances  are  found,  we  may  be  liable  for 
remediation costs, as well as for personal injury and property damage. Environmental laws may require us to incur 
substantial expenses and may materially reduce the affected property’s value or limit our ability to use or ability to 
sell the affected property. Environmental reviews of real property before initiating foreclosure actions may not be 
sufficient  to  detect  all  potential  environmental  hazards.  The  remediation  costs  and  any  other  financial  liabilities 
associated with an environmental hazard could have a material adverse effect on our business, financial condition 
and results of operations.

Liquidity Risk

We Are Subject To Liquidity Risk

We require liquidity to meet our deposit and debt obligations as they come due. Our access to funding sources in 
amounts adequate to finance our activities or on terms that are acceptable to us could be impaired by factors that 
affect us specifically or the financial services industry or economy generally. Factors that could reduce our access to 
liquidity  sources  include  a  downturn  in  the  Texas  economy,  difficult  credit  markets  or  adverse  regulatory  actions 
against  us.  Our  access  to  deposits  may  also  be  affected  by  the  liquidity  needs  of  our  depositors.  In  particular,  a 
substantial majority of our liabilities are demand, savings, interest checking and money market deposits, which are 
payable on demand or upon several days’ notice, while by comparison, a substantial portion of our assets are loans, 
which  cannot  be  called  or  sold  in  the  same  time  frame.  We  may  not  be  able  to  replace  maturing  deposits  and 
advances as necessary in the future, especially if a large number of our depositors sought to withdraw their accounts, 
regardless  of  the  reason.  Our  access  to  deposits  may  be  negatively  impacted  by,  among  other  factors,  continued 
periods  of  low  interest  rates  and  increased  competition  for  deposits,  including  from  new  financial  technology 
competitors. A failure to maintain adequate liquidity could have a material adverse effect on our business, financial 
condition and results of operations.

Operational Risks

Our Accounting Estimates and Risk Management Processes Rely On Analytical and Forecasting Models

The processes we use to estimate our expected credit losses and to measure the fair value of financial instruments, 
as  well  as  the  processes  used  to  estimate  the  effects  of  changing  interest  rates  and  other  market  measures  on  our 
financial  condition  and  results  of  operations,  depends  upon  the  use  of  analytical  and  forecasting  models.  These 
models  reflect  assumptions  that  may  not  be  accurate,  particularly  in  times  of  market  stress  or  other  unforeseen 
circumstances.  Even  if  these  assumptions  are  adequate,  the  models  may  prove  to  be  inadequate  or  inaccurate 
because of other flaws in their design or their implementation, including flaws caused by failures in controls, data 
management, human error or from the reliance on technology. If the models we use for interest rate risk and asset-
liability management are inadequate, we may incur increased or unexpected losses upon changes in market interest 
rates or other market measures. If the models we use for estimating our expected credit losses are inadequate, the 
allowance for credit losses may not be sufficient to support future charge-offs. If the models we use to measure the 
fair  value  of  financial  instruments  are  inadequate,  the  fair  value  of  such  financial  instruments  may  fluctuate 
unexpectedly  or  may  not  accurately  reflect  what  we  could  realize  upon  sale  or  settlement  of  such  financial 
instruments.  Any  such  failure  in  our  analytical  or  forecasting  models  could  have  a  material  adverse  effect  on  our 
business, financial condition and results of operations.

22

The Value Of Our Goodwill and Other Intangible Assets May Decline In The Future

As of December 31, 2021, we had $655.8 million of goodwill and other intangible assets. A significant decline in 
our  expected  future  cash  flows,  a  significant  adverse  change  in  the  business  climate,  slower  growth  rates  or  a 
significant and sustained decline in the price of Cullen/Frost’s common stock may necessitate taking charges in the 
future  related  to  the  impairment  of  our  goodwill  and  other  intangible  assets  which  could  have  a  material  adverse 
effect on our business, financial condition and results of operations.

We Are Subject To Risk Arising From Failure Or Circumvention Of Our Controls and Procedures

Our internal controls, disclosure controls and procedures, and corporate governance procedures are based in part 
on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the controls 
and  procedures  are  met.  Any  failure  or  circumvention  of  our  controls  and  procedures;  failure  to  comply  with 
regulations related to controls and procedures; or failure to comply with our corporate governance procedures could 
have  a  material  adverse  effect  on  our  reputation,  business,  financial  condition  and  results  of  operations,  including 
subjecting  us  to  litigation,  regulatory  fines,  penalties  or  other  sanctions.  Furthermore,  notwithstanding  the 
proliferation of technology and technology-based risk and control systems, our businesses ultimately rely on people 
as our greatest resource, and, from time-to-time, they make mistakes or engage in violations of applicable policies, 
laws, rules or procedures that are not always caught immediately by our technological processes or by our controls 
and other procedures, which are intended to prevent and detect such errors or violations. Human errors, malfeasance 
and other misconduct, including the intentional misuse of client information in connection with insider trading or for 
other purposes, even if promptly discovered and remediated, can result in reputational damage or legal risk and have 
a material adverse effect on our business, financial condition and results of operations.

New Lines Of Business, Products Or Services and Technological Advancements May Subject Us To Additional Risks

From time to time, we implement new lines of business or offer new products and services within existing lines 
of business. There are substantial risks and uncertainties associated with these efforts, particularly in instances where 
the  markets  are  not  fully  developed.  In  developing  and  marketing  new  lines  of  business  and/or  new  products  and 
services  we  invest  significant  time  and  resources.  Initial  timetables  for  the  introduction  and  development  of  new 
lines of business and/or new products or services may not be achieved and price and profitability targets may not 
prove feasible. External factors, such as compliance with regulations, competitive alternatives, and shifting market 
preferences, may also impact the successful implementation of a new line of business or a new product or service. 

The financial services industry is continually undergoing rapid technological change with frequent introductions 
of new technology-driven products and services. Our future success depends, in part, upon our ability to address the 
needs of our customers by using technology to provide products and services that will satisfy customer demands, as 
well  as  to  create  additional  efficiencies  in  our  operations.  Many  of  our  competitors  have  substantially  greater 
resources  to  invest  in  technological  improvements.  We  may  not  be  able  to  effectively  implement  new  technology 
driven products and services or be successful in marketing these products and services to our customers. In addition, 
our  implementation  of  certain  new  technologies,  such  as  those  related  to  artificial  intelligence,  automation  and 
algorithms, in our business processes may have unintended consequences due to their limitations or our failure to 
use  them  effectively.  In  addition,  cloud  technologies  are  also  critical  to  the  operation  of  our  systems,  and  our 
reliance on cloud technologies is growing. Failure to successfully keep pace with technological change affecting the 
financial services industry could have a material adverse effect on our business, financial condition and results of 
operations.

Furthermore, any new line of business, new product or service and/or new technology could have a significant 
impact  on  the  effectiveness  of  our  system  of  internal  controls.  Failure  to  successfully  manage  these  risks  in  the 
development and implementation of new lines of business, new products or services and/or new technologies could 
have a material adverse effect on our business, financial condition and results of operations.

Our Reputation and Our Business Are Subject to Negative Publicity Risk 

Reputation risk, or the risk to our earnings and capital from negative public opinion, is inherent in our business. 
Negative public opinion could adversely affect our ability to keep and attract customers and expose us to adverse 
legal and regulatory consequences. Negative public opinion could result from our actual or alleged conduct in any 
number  of  activities,  including  (i)  lending  practices,  (ii)  branching  strategy,  (iii)  product  and  service  offerings, 
(iv) corporate governance, (v) regulatory compliance, (vi) mergers and acquisitions, (vii) disclosure, (viii) sharing or 
inadequate protection of customer information, (ix) successful or attempted cyber attacks against us, our customers 

23

or  our  third-party  partners  or  vendors  and  (x)  failure  to  discharge  any  publicly  announced  commitments  to 
employees or environmental, social and governance initiatives or to respond adequately to social and sustainability 
concerns  from  the  viewpoint  of  our  stakeholders  from  actions  taken  by  government  regulators  and  community 
organizations in response to our conduct. Negative public opinion could also result from adverse news or publicity 
that  impairs  the  reputation  of  the  financial  services  industry  generally  or  from  the  actions  of  our  employees, 
customers,  affiliates  or  third  parties  with  whom  we  do  business.  In  addition,  our  reputation  or  prospects  may  be 
significantly damaged by adverse publicity or negative information regarding us, whether or not true, that may be 
posted on social media, non-mainstream news services or other parts of the internet, and this risk is magnified by the 
speed and pervasiveness with which information is disseminated through those channels. Because we conduct most 
of  our  business  under  the  “Frost”  brand,  negative  public  opinion  about  one  business  could  affect  our  other 
businesses.

Our  Business,  Financial  Condition  and  Results  Of  Operations  Are  Subject  To  Risk  From  Changes  in  Customer 
Behavior 

Individual, economic, political, industry-specific conditions and other factors outside of our control, such as fuel 
prices, energy costs, real estate values, inflation, taxes or other factors that affect customer income levels, could alter 
anticipated customer behavior, including borrowing, repayment, investment and deposit practices. Such a change in 
these  practices  could  materially  adversely  affect  our  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 us, 
our customers and others in the financial institutions industry.

Cullen/Frost Relies On Dividends From Its Subsidiaries For Most Of Its Revenue

Cullen/Frost is a separate and distinct legal entity from its subsidiaries. It receives substantially all of its revenue 
from dividends from its subsidiaries. These dividends are the principal source of funds to pay dividends on Cullen/
Frost’s  common  stock  and  preferred  stock  and  interest  and  principal  on  Cullen/Frost’s  debt.  Various  federal  and 
state laws and regulations limit the amount of dividends that Frost Bank and certain non-bank subsidiaries may pay 
to Cullen/Frost. Also, Cullen/Frost’s right to participate in a distribution of assets upon a subsidiary’s liquidation or 
reorganization is subject to the prior claims of the subsidiary’s creditors and depositors. In the event Frost Bank is 
unable  to  pay  dividends  to  Cullen/Frost,  Cullen/Frost  may  not  be  able  to  service  debt,  pay  obligations  or  pay 
dividends  on  our  common  stock  or  our  preferred  stock.  The  inability  to  receive  dividends  from  Frost  Bank  could 
have  a  material  adverse  effect  on  our  business,  financial  condition  and  results  of  operations.  See  the  section 
captioned  “Supervision  and  Regulation”  in  Item  1.  Business  and  Note  9  -  Capital  and  Regulatory  Matters  in  the 
notes  to  consolidated  financial  statements  included  in  Item  8.  Financial  Statements  and  Supplementary  Data 
elsewhere in this report.

Our Information Systems May Experience Failure, Interruption Or Breach In Security

In the ordinary course of business, we rely on electronic communications and information systems to conduct our 
operations and to store sensitive data. Any failure, interruption or breach in security of these systems could result in 
significant  disruption  to  our  operations.  Information  security  breaches  and  cybersecurity-related  incidents  include, 
but are not limited to, attempts to access information, including customer and company information, malicious code, 
computer viruses and denial of service attacks that could result in unauthorized access, theft, misuse, loss, release or 
destruction  of  data  (including  confidential  customer  information),  account  takeovers,  unavailability  of  service  or 
other events. These types of threats may derive from human error, fraud or malice on the part of external or internal 
parties, or may result from accidental technological failure. Our technologies, systems, networks and software have 
been  and  continue  to  be  subject  to  cybersecurity  threats  and  attacks,  which  range  from  uncoordinated  individual 
attempts to sophisticated and targeted measures directed at us. Any failures related to upgrades and maintenance of 
our  technology  and  information  systems  could  further  increase  our  information  and  system  security  risk.  Our 
increased use of cloud and other technologies, such as remote work technologies, also increases our risk of being 
subject  to  a  cyber  attack.  The  risk  of  a  security  breach  or  disruption,  particularly  through  cyber  attack  or  cyber 
intrusion, has increased as the number, intensity and sophistication of attempted attacks and intrusions from around 
the world have increased.

Our customers, employees and third parties that we do business with have been, and will continue to be, targeted 
by  parties  using  fraudulent  e-mails  and  other  communications  in  attempts  to  misappropriate  passwords,  bank 
account  information  or  other  personal  information  or  to  introduce  viruses  or  other  malware  programs  to  our 

24

information  systems,  the  information  systems  of  our  merchants  or  third-party  service  providers  and/or  our 
customers' personal devices, which are beyond our security control systems. Though we endeavor to mitigate these 
threats through product improvements, use of encryption and authentication technology and customer and employee 
education, such cyber attacks against us, our merchants, our third-party service providers and our customers remain 
a serious issue and have been successful in the past. 

Although we make significant efforts to maintain the security and integrity of our information systems and have 
implemented various measures to manage the risks of a security breach or disruption, there can be no assurance that 
our security efforts and measures will be effective or that attempted security breaches or disruptions would not be 
successful  or  damaging.  Even  well  protected  information,  networks,  systems  and  facilities  remain  potentially 
vulnerable to attempted security breaches or disruptions because the techniques used in such attempts are constantly 
evolving and generally are not recognized until launched against a target, and in some cases are designed not to be 
detected  and,  in  fact,  may  not  be  detected.  Accordingly,  we  may  be  unable  to  anticipate  these  techniques  or  to 
implement  adequate  security  barriers  or  other  preventative  measures,  and  thus  it  is  virtually  impossible  for  us  to 
entirely  mitigate  this  risk.  Furthermore,  in  the  event  of  a  cyber  attack,  we  may  be  delayed  in  identifying  or 
responding  to  the  attack,  which  could  increase  the  negative  impact  of  the  cyber  attack  on  our  business,  financial 
condition and results of operations. While we maintain specific “cyber” insurance coverage, which would apply in 
the  event  of  various  breach  scenarios,  the  amount  of  coverage  may  not  be  adequate  in  any  particular  case. 
Furthermore,  because  cyber  threat  scenarios  are  inherently  difficult  to  predict  and  can  take  many  forms,  some 
breaches may not be covered under our cyber insurance coverage. A security breach or other significant disruption 
of our information systems or those related to our customers, merchants or our third-party vendors, including as a 
result  of  cyber  attacks,  could  (i)  disrupt  the  proper  functioning  of  our  networks  and  systems  and  therefore  our 
operations  and/or  those  of  our  customers;  (ii)  result  in  the  unauthorized  access  to,  and  destruction,  loss,  theft, 
misappropriation  or  release  of  confidential,  sensitive  or  otherwise  valuable  information  of  ours  or  our  customers; 
(iii)  result  in  a  violation  of  applicable  privacy,  data  breach  and  other  laws,  subjecting  us  to  additional  regulatory 
scrutiny and exposing us to civil litigation, enforcement actions, governmental fines and possible financial liability; 
(iv)  require  significant  management  attention  and  resources  to  remedy  the  damages  that  result;  or  (v)  harm  our 
reputation or cause a decrease in the number of customers that choose to do business with us. The occurrence of any 
of the foregoing could have a material adverse effect on our business, financial condition and results of operations. 

Our Operations Rely On Certain External Vendors

We  rely  on  certain  external  vendors  to  provide  products  and  services  necessary  to  maintain  our  day-to-day 
operations. These third-party vendors are sources of operational and informational security risk to us, including risks 
associated  with  operational  errors,  information  system  failures,  interruptions  or  breaches  and  unauthorized 
disclosures  of  sensitive  or  confidential  client  or  customer  information.  If  these  vendors  encounter  any  of  these 
issues, or if we have difficulty communicating with them, we could be exposed to disruption of operations, loss of 
service  or  connectivity  to  customers,  reputational  damage,  and  litigation  risk  that  could  have  a  material  adverse 
effect on our business and, in turn, our financial condition and results of operations.

In  addition,  our  operations  are  exposed  to  risk  that  these  vendors  will  not  perform  in  accordance  with  the 
contracted  arrangements  under  service  level  agreements.  Although  we  have  selected  these  external  vendors 
carefully,  we  do  not  control  their  actions.  The  failure  of  an  external  vendor  to  perform  in  accordance  with  the 
contracted arrangements under service level agreements, because of changes in the vendor’s organizational structure, 
financial condition, support for existing products and services or strategic focus or for any other reason, could be 
disruptive to our operations, which could have a material adverse effect on our business and, in turn, our financial 
condition and results of operations. Replacing these external vendors could also entail significant delay and expense.

We Are Subject To Litigation Risk Pertaining To Fiduciary Responsibility

From time to time, customers make claims and take legal action pertaining to our performance of our fiduciary 
responsibilities.  Whether  customer  claims  and  legal  action  related  to  our  performance  of  our  fiduciary 
responsibilities are founded or unfounded, if such claims and legal actions are not resolved in a manner favorable to 
us  they  may  result  in  significant  financial  liability  and/or  adversely  affect  the  market  perception  of  us  and  our 
products and services as well as impact customer demand for those products and services. Any financial liability or 
reputational  damage  could  have  a  material  adverse  effect  on  our  business,  financial  condition  and  results  of 
operations.

25

We Are Subject To Litigation Risk Pertaining To Intellectual Property

Banking  and  other  financial  services  companies,  including  us,  rely  on  technology  companies  to  provide 
information  technology  products  and  services  necessary  to  support  day-to-day  operations.  Technology  companies 
frequently enter into litigation based on allegations of patent infringement or other violations of intellectual property 
rights. In addition, patent holding companies seek to monetize patents they have purchased or otherwise obtained. 
Competitors of our vendors, or other individuals or companies, have from time to time claimed to hold intellectual 
property sold to us by our vendors or in use by us and we are, and may in the future be, named as defendants in 
various related legal claims. Such claims may increase in the future as the financial services sector becomes more 
reliant on information technology vendors. The plaintiffs in these actions frequently seek injunctions and substantial 
damages and may also seek to enter into licensing agreements with us to obtain ongoing fees.

Regardless of the scope or validity of such patents or other intellectual property rights, or the merits of any claims 
by  potential  or  actual  litigants,  we  may  have  to  engage  in  protracted  litigation.  Such  litigation  is  often  expensive, 
time-consuming, disruptive to our operations and distracting to management. If we are found to infringe upon one or 
more patents or other intellectual property rights, we may be required to pay substantial damages or royalties to a 
third-party. In certain cases, we have and in the future may consider entering into licensing agreements for disputed 
intellectual property, although no assurance can be given that such licenses can be obtained on acceptable terms or 
that litigation will not occur. These licenses may also significantly increase our operating expenses. If legal matters 
related to intellectual property claims were resolved against us or settled, we could be required to make payments in 
amounts that could have a material adverse effect on our business, financial condition and results of operations.

Financial Services Companies Depend On The Accuracy and Completeness Of Information About Customers and 
Counterparties

In deciding whether to extend credit or enter into other transactions, we rely on information furnished by or on 
behalf of customers and counterparties, including financial statements, credit reports and other financial information. 
We  also  rely  on  representations  of  those  customers,  counterparties  or  other  third  parties,  such  as  independent 
auditors,  as  to  the  accuracy  and  completeness  of  that  information.  Reliance  on  inaccurate  or  misleading  financial 
statements,  credit  reports  or  other  financial  information  could  have  a  material  adverse  impact  on  our  business, 
financial condition and results of operations.

External and Market-Related Risks

Our Profitability Depends Significantly On Economic Conditions In The State Of Texas

Our success depends substantially on the general economic conditions of the State of Texas and the specific local 
markets in which we operate. Unlike larger national or other regional banks that are more geographically diversified, 
we  provide  banking  and  financial  services  primarily  to  customers  across  Texas  through  financial  centers  in  the 
Austin, Corpus Christi, Dallas, Fort Worth, Houston, Permian Basin, Rio Grande Valley and San Antonio regions. 
The local economic conditions in these areas have a significant impact on the demand for our products and services 
as well as the ability of our customers to repay loans, the value of the collateral securing loans and the stability of 
our deposit funding sources. Moreover, all of the securities in our municipal bond portfolio were issued by political 
subdivisions or agencies within the State of Texas. A significant decline in general economic conditions in Texas, 
whether  caused  by  recession,  inflation,  unemployment,  changes  or  prolonged  stagnation  in  oil  prices,  changes  in 
securities  markets,  acts  of  terrorism,  pandemics,  natural  disasters,  climate  change,  outbreak  of  hostilities  or  other 
international  or  domestic  occurrences  or  other  factors  could  impact  these  local  economic  conditions  and,  in  turn, 
have a material adverse effect on our business, financial condition and results of operations.

We Are Subject to Risk Arising From The Soundness Of Other Financial Institutions and Counterparties

Financial services institutions are interrelated as a result of trading, clearing, counterparty, or other relationships. 
We  have  exposure  to  many  different  industries  and  counterparties,  and  routinely  execute  transactions  with 
counterparties in the financial services industry, including commercial banks, brokers and dealers, investment banks, 
and  other  institutional  clients.  Many  of  these  transactions  expose  us  to  credit  risk  in  the  event  of  a  default  by  a 
counterparty  or  client.  In  addition,  our  credit  risk  may  be  exacerbated  when  the  collateral  held  by  us  cannot  be 
realized upon or is liquidated at prices not sufficient to recover the full amount of the credit or derivative exposure 
due  to  us.  Increased  interconnectivity  amongst  financial  institutions  also  increases  the  risk  of  cyber  attacks  and 

26

information system failures for financial institutions. Any such losses could have a material adverse effect on our 
business, financial condition and results of operations.

We Operate In A Highly Competitive Industry and Market Area

We  face  substantial  competition  in  all  areas  of  our  operations  from  a  variety  of  different  competitors,  many  of 
which  are  larger  and  may  have  more  financial  resources  than  us.  Such  competitors  primarily  include  national, 
regional,  and  community  banks  within  the  various  markets  where  we  operate.  Recent  regulation  has  reduced  the 
regulatory  burden  of  large  bank  holding  companies,  and  raised  the  asset  thresholds  at  which  more  onerous 
requirements  apply,  which  could  cause  certain  large  bank  holding  companies  with  less  than  $250  billion  in  total 
consolidated assets, which were previously subject to more stringent enhanced prudential standards, to become more 
competitive or to pursue expansion more aggressively.

We also face competition from many other types of financial institutions, including, without limitation, savings 
and  loans,  credit  unions,  finance  companies,  brokerage  firms,  insurance  companies  and  other  financial 
intermediaries.  The  financial  services  industry  could  become  even  more  competitive  as  a  result  of  legislative, 
regulatory and technological changes and continued consolidation. 

Also, technology and other changes have lowered barriers to entry and made it possible for non-banks to offer 
products and services traditionally provided by banks. In particular, the activity of fintechs/wealthtechs has grown 
significantly over recent years and is expected to continue to grow. Some fintechs/wealthtechs are not subject to the 
same  regulation  as  we  are,  which  may  allow  them  to  be  more  competitive.  Fintechs/wealthtechs  have  and  may 
continue to offer bank or bank-like products and a number of such organizations have applied for bank or industrial 
loan  charters  while  others  have  partnered  with  existing  banks  to  allow  them  to  offer  deposit  products  to  their 
customers.  Increased  competition  from  fintechs/wealthechs  and  the  growth  of  digital  banking  may  also  lead  to 
pricing pressures as competitors offer more low-fee and no-fee products.

Additionally, consumers can maintain funds that would have historically been held as bank deposits in brokerage 
accounts or mutual funds. Consumers can also complete transactions such as paying bills and/or transferring funds 
directly  without  the  assistance  of  banks.  The  process  of  eliminating  banks  as  intermediaries,  known  as 
“disintermediation,” could result in the loss of fee income, as well as the loss of customer deposits and the related 
income generated from those deposits. Further, many of our competitors have fewer regulatory constraints and may 
have  lower  cost  structures  than  us.  Additionally,  due  to  their  size,  many  competitors  may  be  able  to  achieve 
economies of scale and, as a result, may offer a broader range of products and services as well as better pricing for 
those  products  and  services  than  we  can.  Our  ability  to  compete  successfully  depends  on  a  number  of  factors, 
including, among other things, (i) the ability to develop, maintain and build long-term customer relationships based 
on top quality service, high ethical standards and safe, sound assets; (ii) the ability to expand within our marketplace 
and  with  our  market  position;  (iii)  the  scope,  relevance  and  pricing  of  products  and  services  offered  to  meet 
customer  needs  and  demands;  (iv)  the  rate  at  which  we  introduce  new  products  and  services  relative  to  our 
competitors;  (v)  customer  satisfaction  with  our  level  of  service;  and  (vi)  industry  and  general  economic  trends. 
Failure to perform in any of these areas could significantly weaken our competitive position, which could adversely 
affect our growth and profitability, which, in turn, could have a material adverse effect on our business, financial 
condition and results of operations.

Compliance and Regulatory Risks

We Are Subject To Extensive Government Regulation and Supervision and Related Enforcement Powers and Other 
Legal Remedies

We, primarily through Cullen/Frost, Frost Bank and certain non-bank subsidiaries, are subject to extensive federal 
and  state  regulation  and  supervision,  which  vests  a  significant  amount  of  discretion  in  the  various  regulatory 
authorities. Banking regulations are primarily intended to protect depositors’ funds, federal deposit insurance funds 
and  the  banking  system  as  a  whole,  not  security  holders.  These  regulations  and  supervisory  guidance  affect  our 
lending practices, capital structure, investment practices, dividend policy and growth, among other things. Congress 
and  federal  regulatory  agencies  continually  review  banking  laws,  regulations  and  policies  for  possible  changes. 
Changes to statutes, regulations or regulatory policies or supervisory guidance, including changes in interpretation or 
implementation  of  statutes,  regulations,  policies  or  supervisory  guidance,  could  affect  us  in  substantial  and 
unpredictable  ways.  Such  changes  could  subject  us  to  additional  costs,  limit  the  types  of  financial  services  and 
products we may offer, limit our ability to return capital to shareholders or conduct certain activities, and/or increase 

27

the ability of non-banks to offer competing financial services and products, among other things. Failure to comply 
with  laws,  regulations,  policies  or  supervisory  guidance  could  result  in  enforcement  and  other  legal  actions  by 
Federal or state authorities, including criminal and civil penalties, the loss of FDIC insurance, the revocation of a 
banking charter, enforcement actions or sanctions by regulatory agencies, significant fines and civil money penalties 
and/or  reputational  damage.  In  this  regard,  government  authorities,  including  the  bank  regulatory  agencies,  are 
pursuing  aggressive  enforcement  actions  with  respect  to  compliance  and  other  legal  matters  involving  financial 
activities, which heightens the risks associated with actual and perceived compliance failures. Directives issued to 
enforce such actions may be confidential and thus, in some instances, we are not permitted to publicly disclose these 
actions. Any of the foregoing could have a material adverse effect on our business, financial condition and results of 
operations.  See  the  sections  captioned  “Supervision  and  Regulation”  included  in  Item  1.  Business  and  Note  9  - 
Capital  and  Regulatory  Matters  in  the  notes  to  consolidated  financial  statements  included  in  Item  8.  Financial 
Statements and Supplementary Data elsewhere in this report.

The  Repeal  Of  Federal  Prohibitions  On  Payment  Of  Interest  On  Demand  Deposits  Could  Increase  Our  Interest 
Expense

All  federal  prohibitions  on  the  ability  of  financial  institutions  to  pay  interest  on  demand  deposit  accounts  were 
repealed  as  part  of  the  Dodd-Frank  Act  beginning  on  July  21,  2011.  As  a  result,  some  financial  institutions  offer 
interest on demand deposits to compete for customers. We do not yet know what interest rates other institutions may 
offer as market interest rates increase. Our interest expense will increase and our net interest margin will decrease if 
we begin offering interest on demand deposits to attract additional customers or maintain current customers, which 
could have a material adverse effect on our business, financial condition and results of operations.

We Are Subject To Government Regulation and Oversight Relating to Data and Privacy Protection

Our  business  requires  the  collection  and  retention  of  large  volumes  of  customer  data,  including  personally 
identifiable  information  in  various  information  systems  that  we  maintain  and  in  those  maintained  by  third  parties 
with  whom  we  contract  to  provide  data  services.  We  also  maintain  important  internal  company  data  such  as 
personally  identifiable  information  about  our  employees  and  information  relating  to  our  operations.  The  integrity 
and protection of that customer and company data is important to us. Our collection of such customer and company 
data is subject to extensive regulation and oversight.

We are subject to laws and regulations relating to the privacy of the information of our customers, employees and 
others,  and  any  failure  to  comply  with  these  laws  and  regulations  could  expose  us  to  liability  and/or  reputational 
damage.  As  new  privacy-related  laws  and  regulations  are  implemented,  the  time  and  resources  needed  for  us  to 
comply  with  such  laws  and  regulations,  as  well  as  our  potential  liability  for  non-compliance  and  reporting 
obligations in the case of data breaches, may significantly increase.

Risks Related to Acquisition Activity

Potential Acquisitions May Disrupt Our Business and Dilute Stockholder Value

We  generally  seek  merger  or  acquisition  partners  that  are  culturally  similar  and  have  experienced  management 
and  possess  either  significant  market  presence  or  have  potential  for  improved  profitability  through  financial 
management,  economies  of  scale  or  expanded  services.  Acquiring  other  banks,  businesses,  or  branches  involves 
various  risks  commonly  associated  with  acquisitions,  including,  among  other  things,  (i)  potential  exposure  to 
unknown or contingent liabilities of the target company; (ii) exposure to potential asset quality issues of the target 
company; (iii) potential disruption to our business; (iv) potential diversion of our management’s time and attention; 
(v) the possible loss of key employees and customers of the target company; (vi) difficulty in estimating the value of 
the  target  company;  and  (vii)  potential  changes  in  banking  or  tax  laws  or  regulations  that  may  affect  the  target 
company.

Acquisitions  typically  involve  the  payment  of  a  premium  over  book  and  market  values,  and,  therefore,  some 
dilution  of  our  tangible  book  value  and  net  income  per  common  share  may  occur  in  connection  with  any  future 
transaction. Acquisitions may also result in potential dilution to existing stockholders of our earnings per share if we 
issue  common  stock  in  connection  with  the  acquisition.  Furthermore,  failure  to  realize  the  expected  revenue 
increases,  cost  savings,  increases  in  geographic  or  product  presence,  and/or  other  projected  benefits  from  an 
acquisition could have a material adverse effect on our business, financial condition and results of operations.

28

Acquisitions May Be Delayed, Impeded, Or Prohibited Due To Regulatory Issues

Acquisitions  by  financial  institutions,  including  us,  are  subject  to  approval  by  a  variety  of  federal  and  state 
regulatory  agencies  (collectively,  “regulatory  approvals”).  The  process  for  obtaining  these  required  regulatory 
approvals  has  become  substantially  more  difficult  since  the  global  financial  crisis,  and  our  ability  to  engage  in 
certain merger or acquisition transactions depends on the bank regulators' views at the time as to our capital levels, 
quality of management, and overall condition, in addition to their assessment of a variety of other factors, including 
our compliance with law. Regulatory approvals could be delayed, impeded, restrictively conditioned or denied due 
to existing or new regulatory issues we have, or may have, with regulatory agencies, including, without limitation, 
issues related to Bank Secrecy Act compliance, Community Reinvestment Act issues, fair lending laws, fair housing 
laws,  consumer  protection  laws,  unfair,  deceptive,  or  abusive  acts  or  practices  regulations  and  other  laws  and 
regulations.  We  may  fail  to  pursue,  evaluate  or  complete  strategic  and  competitively  significant  acquisition 
opportunities  as  a  result  of  our  inability,  or  perceived  or  anticipated  inability,  to  obtain  regulatory  approvals  in  a 
timely  manner,  under  reasonable  conditions  or  at  all.  Difficulties  associated  with  potential  acquisitions  that  may 
result  from  these  factors  could  have  a  material  adverse  effect  on  our  business,  financial  condition  and  results  of 
operations.

Risks Associated With Our Common Stock

The Trading Volume In Our Common Stock Is Less Than That Of Other Larger Financial Services Companies

Although our common stock is listed for trading on the New York Stock Exchange (“NYSE”), the trading volume 
in our common stock is less than that of other, larger financial services companies. A public trading market having 
the desired characteristics of depth, liquidity and orderliness depends on the presence in the marketplace of willing 
buyers  and  sellers  of  our  common  stock  at  any  given  time.  This  presence  depends  on  the  individual  decisions  of 
investors  and  general  economic  and  market  conditions  over  which  we  have  no  control.  Given  the  lower  trading 
volume of our common stock, significant sales of our common stock, or the expectation of these sales, could cause 
our stock price to fall.

Cullen/Frost May Not Continue To Pay Dividends On Its Common Stock In The Future

Holders of Cullen/Frost common stock are only entitled to receive such dividends as its board of directors may 
declare  out  of  funds  legally  available  for  such  payments.  Although  Cullen/Frost  has  historically  declared  cash 
dividends on its common stock, it is not required to do so and may reduce or eliminate its common stock dividend in 
the future. This could adversely affect the market price of Cullen/Frost’s common stock. Also, Cullen/Frost is a bank 
holding  company,  and  its  ability  to  declare  and  pay  dividends  is  dependent  on  certain  federal  regulatory 
considerations, including the guidelines of the Federal Reserve Board regarding capital adequacy and dividends. 

As  more  fully  discussed  in  Note  9  -  Capital  and  Regulatory  Matters  in  the  notes  to  consolidated  financial 
statements included in Item 8. Financial Statements and Supplementary Data elsewhere in this report, our ability to 
declare or pay dividends on our common stock may also be subject to certain restrictions in the event that we elect to 
defer  the  payment  of  interest  on  our  junior  subordinated  deferrable  interest  debentures  or  do  not  declare  and  pay 
dividends on our Series B Preferred Stock.

An Investment In Our Common Stock Is Not An Insured Deposit

Our  common  stock  is  not  a  bank  deposit  and,  therefore,  is  not  insured  against  loss  by  the  Federal  Deposit 
Insurance  Corporation  (“FDIC”),  any  other  deposit  insurance  fund  or  by  any  other  public  or  private  entity. 
Investment  in  our  common  stock  is  inherently  risky  for  the  reasons  described  in  this  “Risk  Factors”  section  and 
elsewhere  in  this  report  and  is  subject  to  the  same  market  forces  that  affect  the  price  of  common  stock  in  any 
company. As a result, if you acquire our common stock, you could lose some or all of your investment.

Certain Banking Laws May Have An Anti-Takeover Effect

Provisions of federal banking laws, including regulatory approval requirements, could make it more difficult for a 
third party to acquire us, even if doing so would be perceived to be beneficial to our shareholders. These provisions 
effectively inhibit a non-negotiated merger or other business combination, which, in turn, could adversely affect the 
market price of our common stock.

29

Risks Related to the COVID-19 Pandemic

Our Business, Financial Condition, Liquidity and Results of Operations Have Been, and Will Likely Continue to be, 
Adversely Affected by the COVID-19 Pandemic.

The  COVID-19  pandemic  has  created  economic  and  financial  disruptions  that  have  adversely  affected,  and  are 
likely to continue to adversely affect, our business, financial condition, liquidity and results of operations. The extent 
to which the COVID-19 pandemic will continue to negatively affect our business, financial condition, liquidity and 
results of operations will depend on future developments, which are highly uncertain and cannot be predicted and 
many of which are outside of our control, including the scope and duration of the pandemic, the emergence of new 
variants, the effectiveness of our Business Continuity and Health Emergency Response plans, the direct and indirect 
impact of the pandemic on our employees, customers, clients, counterparties and service providers, as well as other 
market participants, and actions taken, or that may yet be taken, or inaction, by governmental authorities and other 
third parties in response to the pandemic. Should the pandemic continue for a more extended period or worsen, we 
may  face  additional  circumstances  such  as  significant  draws  on  credit  lines  should  customers  seek  to  increase 
liquidity.  Furthermore,  should  the  pandemic  continue,  we  may  experience  increased  rates  of  employee  illness  or 
unavailability, and may experience challenges recruiting new employees.

Any  disruption  to  our  ability  to  deliver  financial  products  or  services  to,  or  interact  with,  our  clients  and 
customers  could  result  in  losses  or  increased  operational  costs,  regulatory  fines,  penalties  and  other  sanctions,  or 
harm  our  reputation.  We  are  also  subject  to  litigation  and  reputational  risk  arising  from  our  response  to  the 
COVID-19 pandemic. The length of the pandemic and the efficacy of the measures being put in place to address it 
are  unknown  as  efforts  to  combat  the  virus  have  been  complicated  by  viral  variants  and  uneven  access  to,  and 
acceptance  and  effectiveness  of,  vaccines  globally.  To  the  extent  the  pandemic  adversely  affects  our  business, 
financial condition, liquidity or results of operations, it may also have the effect of heightening many of the other 
risks described in this report. See the section captioned “COVID-19 Effects, Actions and Recent Developments” in 
Part II. Financial Information, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of 
Operations elsewhere in this report for further discussion.

General Risk Factors

We  are  Subject  To  Risk  From  Fluctuating  Conditions  In  The  Financial  Markets  and  Economic  and  Political 
Conditions Generally

Our  success  depends,  to  a  certain  extent,  upon  local,  national  and  global  economic  and  political  conditions,  as 
well  as  governmental  monetary  policies.  Our  financial  performance  generally,  and  in  particular  the  ability  of 
borrowers to pay interest on and repay principal of outstanding loans and the value of collateral securing those loans, 
as  well  as  demand  for  loans  and  other  products  and  services  we  offer,  is  highly  dependent  upon  the  business 
environment in the markets where we operate, in the State of Texas and in the United States as a whole. A favorable 
business environment is generally characterized by, among other factors, economic growth, efficient capital markets, 
low inflation, low unemployment, high business and investor confidence, and strong business earnings. Unfavorable 
or uncertain economic and market conditions can be caused by a decline in economic growth both in the U.S. and 
internationally; declines in business activity or investor or business confidence; limitations on the availability of or 
increases  in  the  cost  of  credit  and  capital;  increases  in  inflation  or  interest  rates;  high  unemployment;  oil  price 
volatility;  natural  disasters;  trade  policies  and  tariffs;  or  a  combination  of  these  or  other  factors.  While  recent 
economic conditions in the State of Texas, the United States and worldwide have seen improving trends since the 
onset  of  the  COVID-19  pandemic,  there  can  be  no  assurance  that  this  improvement  will  continue.  Evolving 
responses from federal and state governments and other regulators, and our customers or our third-party partners or 
vendors, to new challenges such as climate change have impacted and could continue to impact the economic and 
political  conditions  under  which  we  operate.  Economic  and  inflationary  pressure  on  consumers  and  uncertainty 
regarding continuing economic improvement could result in changes in consumer and business spending, borrowing 
and savings habits. Such conditions could have a material adverse effect on the credit quality of our loans and our 
business, financial condition and results of operations.

30

Changes In The Federal, State Or Local Tax Laws May Negatively Impact Our Financial Performance and We Are 
Subject To Examinations and Challenges By Tax Authorities

We are subject to federal and applicable state tax laws and regulations. Changes in these tax laws and regulations, 
some of which may be retroactive to previous periods, could increase our effective tax rates and, as a result, could 
negatively  affect  our  current  and  future  financial  performance.  Furthermore,  tax  laws  and  regulations  are  often 
complex and require interpretation. In the normal course of business, we are routinely subject to examinations and 
challenges  from  federal  and  applicable  state  tax  authorities  regarding  the  amount  of  taxes  due  in  connection  with 
investments  we  have  made  and  the  businesses  in  which  we  have  engaged.  Recently,  federal  and  state  taxing 
authorities have become increasingly aggressive in challenging tax positions taken by financial institutions. These 
tax positions may relate to tax compliance, sales and use, franchise, gross receipts, payroll, property and income tax 
issues, including tax base, apportionment and tax credit planning. The challenges made by tax authorities may result 
in  adjustments  to  the  timing  or  amount  of  taxable  income  or  deductions  or  the  allocation  of  income  among  tax 
jurisdictions. If any such challenges are made and are not resolved in our favor, they could have a material adverse 
effect on our business, financial condition and results of operations.

We May Need To Raise Additional Capital In The Future, and Such Capital May Not Be Available When Needed Or 
At All

We may need to raise additional capital in the future to provide us with sufficient capital resources and liquidity 
to  meet  our  commitments  and  business  needs,  particularly  if  our  asset  quality  or  earnings  were  to  deteriorate 
significantly. Our ability to raise additional capital, if needed, will depend on, among other things, conditions in the 
capital markets at that time, which are outside of our control, and our financial condition. Economic conditions and 
the loss of confidence in financial institutions may increase our cost of funding and limit access to certain customary 
sources  of  capital,  including  inter-bank  borrowings,  repurchase  agreements  and  borrowings  from  the  discount 
window of the Federal Reserve.

We cannot assure that such capital will be available on acceptable terms or at all. Any occurrence that may limit 
our access to the capital markets, such as a decline in the confidence of debt purchasers, depositors of Frost Bank or 
counterparties  participating  in  the  capital  markets,  or  a  downgrade  of  Cullen/Frost’s  or  Frost  Bank’s  debt  ratings, 
may adversely affect our capital costs and our ability to raise capital and, in turn, our liquidity. Moreover, if we need 
to raise capital in the future, we may have to do so when many other financial institutions are also seeking to raise 
capital and would have to compete with those institutions for investors. An inability to raise additional capital on 
acceptable terms when needed could have a materially adverse effect on our business, financial condition and results 
of operations.

Our Stock Price Can Be Volatile

Stock  price  volatility  may  make  it  more  difficult  for  you  to  resell  your  common  stock  when  you  want  and  at 
prices  you  find  attractive.  Our  stock  price  can  fluctuate  significantly  in  response  to  a  variety  of  factors  including, 
among  other  things,  (i)  actual  or  anticipated  variations  in  quarterly  results  of  operations;  (ii)  recommendations  by 
securities analysts; (iii) operating and stock price performance of other companies that investors deem comparable to 
us; (iv) news reports relating to trends, concerns and other issues in the financial services industry; (v) perceptions in 
the marketplace regarding us and/or our competitors; (vi) new technology used, or services offered, by competitors; 
(vii) the issuance by us of additional securities, including common stock and securities that are convertible into or 
exchangeable for, or that represent the right to receive, common stock; (viii) sales of a large block of shares of our 
common  stock  or  similar  securities  in  the  market  after  an  equity  offering,  or  the  perception  that  such  sales  could 
occur;  (ix)  significant  acquisitions  or  business  combinations,  strategic  partnerships,  joint  ventures  or  capital 
commitments  by  or  involving  us  or  our  competitors;  (x)  failure  to  integrate  acquisitions  or  realize  anticipated 
benefits from acquisitions; (xi) changes in government regulations; and (xii) geopolitical conditions such as acts or 
threats of terrorism or military conflicts.

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

31

Changes In Accounting Standards Could Materially Impact Our Financial Statements

From  time  to  time  accounting  standards  setters  change  the  financial  accounting  and  reporting  standards  that 
govern  the  preparation  of  our  financial  statements.  These  changes  can  be  difficult  to  predict  and  can  materially 
impact  how  we  record  and  report  our  financial  condition  and  results  of  operations.  In  some  cases,  we  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.  See  Note  20  -  Accounting  Standards  Updates  in  the  notes  to 
consolidated financial statements included in Item 8. Financial Statements and Supplementary Data elsewhere in this 
report for further information regarding pending accounting standards updates.

We May Not Be Able To Attract and Retain Skilled People

Our success depends, in large part, on our ability to attract and retain key people. Competition for the best people 
in  many  activities  engaged  in  by  us  is  intense  including  with  respect  to  compensation  and  emerging  workplace 
practices, accommodations and remote work options, and we may not be able to hire people or to retain them. We do 
not  currently  have  employment  agreements  or  non-competition  agreements  with  any  of  our  senior  officers.  The 
unexpected  loss  of  services  of  key  personnel  could  have  a  material  adverse  impact  on  our  business,  financial 
condition and results of operations because of their customer relationships, skills, knowledge of our market, years of 
industry  experience  and  the  difficulty  of  promptly  finding  qualified  replacement  personnel.  In  addition,  the  scope 
and  content  of  U.S.  banking  regulators'  policies  on  incentive  compensation,  as  well  as  changes  to  these  policies, 
could adversely affect our ability to hire, retain and motivate our key employees.

Severe  Weather,  Natural  Disasters,  Acts  Of  War  Or  Terrorism  and  Other  Adverse  External  Events  Could 
Significantly Impact Our Business and Our Customers

Severe  weather,  natural  disasters,  acts  of  war  or  terrorism  and  other  adverse  external  events  could  have  a 
significant impact on our ability to conduct business. In addition, such events could affect the stability of our deposit 
base, impair the ability of borrowers to repay outstanding loans, impair the value of collateral securing loans, cause 
significant property damage, result in loss of revenue and/or cause us to incur additional expenses. Furthermore, the 
occurrence of any such event in the future could have a material adverse effect on our business, which, in turn, could 
have a material adverse effect on our financial condition and results of operations.

Climate Change Could Have a Material Negative Impact on Us and Our Customers

Our business, as well as the operations and activities of our customers, could be negatively impacted by climate 
change.  Climate  change  presents  both  immediate  and  long-term  risks  to  us  and  our  customers  and  these  risks  are 
expected to increase over time. Climate changes presents multi-faceted risks, including (i) operational risk from the 
physical effects of climate events on our facilities and other assets as well as those of our customers; (ii) credit risk 
from borrowers with significant exposure to climate risk; and (iii) reputational risk from stakeholder concerns about 
our  practices  related  to  climate  change,  our  carbon  footprint  and  our  business  relationships  with  customers  who 
operate in carbon-intensive industries. Our business, reputation and ability to attract and retain employees may also 
be harmed if our response to climate changed is perceived to be ineffective or insufficient.

Climate change exposes us to physical risk as its effects may lead to more frequent and more extreme weather 
events, such as prolonged droughts or flooding, tornados, hurricanes, wildfires and extreme seasonal weather; and 
longer-term shifts, such as increasing average temperatures, ozone depletion and rising sea levels. Such events and 
long-term  shifts  may  damage,  destroy  or  otherwise  impact  the  value  or  productivity  of  our  properties  and  other 
assets;  reduce  the  availability  of  insurance;  and/or  disrupt  our  operations  and  other  activities  through  prolonged 
outages. Such events and long-term shifts may also have a significant impact on our customers, which could amplify 
credit  risk  by  diminishing  borrowers’  repayment  capacity  or  collateral  values,  and  other  businesses  and 
counterparties  with  whom  we  transact,  which  could  have  a  broader  impact  on  the  economy,  supply  chains  and 
distribution networks. 

Climate  change  also  exposes  us  to  transition  risks  associated  with  the  transition  to  a  less  carbon-dependent 
economy.  Transition  risks  may  result  from  changes  in  policies;  laws  and  regulations;  technologies;  and/or  market 
preferences  to  address  climate  change.  Such  changes  could  materially,  negatively  impact  our  business,  results  of 
operations, financial condition and/or our reputation, in addition to having a similar impact on our customers. We 
have customers who operate in carbon-intensive industries like oil and gas that are exposed to climate risks, such as 
those risks related to the transition to a less carbon-dependent economy, as well as customers who operate in low-

32

carbon industries that may be subject to risks associated with new technologies. Federal and state banking regulators 
and  supervisory  authorities,  investors  and  other  stakeholders  have  increasingly  viewed  financial  institutions  as 
important in helping to address the risks related to climate change both directly and with respect to their customers, 
which may result in financial institutions coming under increased pressure regarding the disclosure and management 
of their climate risks and related lending and investment activities. Given that climate change could impose systemic 
risks  upon  the  financial  sector,  either  via  disruptions  in  economic  activity  resulting  from  the  physical  impacts  of 
climate  change  or  changes  in  policies  as  the  economy  transitions  to  a  less  carbon-intensive  environment,  we  face 
regulatory risk of increasing focus on our resilience to climate-related risks, including in the context of stress testing 
for various climate stress scenarios. Ongoing legislative or regulatory uncertainties and changes regarding climate 
risk management and practices may result in higher regulatory, compliance, credit and reputational risks and costs.

Stock Repurchase Plans

From  time  to  time,  our  board  of  directors  has  authorized  stock  repurchase  plans.  In  general,  stock  repurchase 
plans allow us to proactively manage our capital position and return excess capital to shareholders. Shares purchased 
under  such  plans  also  provide  us  with  shares  of  common  stock  necessary  to  satisfy  obligations  related  to  stock 
compensation  awards.  On  January  26,  2022,  our  board  of  directors  authorized  a  $100.0  million  stock  repurchase 
plan,  allowing  us  to  repurchase  shares  of  our  common  stock  over  a  one-year  period  from  time  to  time  at  various 
prices  in  the  open  market  or  through  private  transactions.  Under  prior  stock  repurchase  plans,  we  repurchased, 
177,834 shares at a total cost of $13.7 million during 2020 and 699,031 shares at a total cost of $67.2 million during 
2019. No shares were repurchased under a stock repurchase plan during 2021.

The following table provides information with respect to purchases made by or on behalf of us or any “affiliated

COVID-19 Effects, Actions and Recent Developments

Overview. During 2020 and to a lesser extent in 2021, our business has been, and continues to be, impacted by 
the  ongoing  outbreak  of  COVID-19.  In  March  2020,  COVID-19  was  declared  a  pandemic  by  the  World  Health 
Organization  and  a  national  emergency  by  the  President  of  the  United  States.  Efforts  to  limit  the  spread  of 
COVID-19 have included quarantines/shelter-in-place orders, the closure or limiting capacity of businesses, travel 
restrictions,  supply  chain  limitations  and  prohibitions  on  public  gatherings,  among  other  things,  throughout  many 
parts of the United States and, in particular, the markets in which we operate. As the current pandemic is ongoing 
and  dynamic  in  nature,  there  are  many  uncertainties  related  to  COVID-19  including,  among  other  things,  its 
severity;  the  duration  of  the  outbreak;  the  impact  to  our  customers,  employees  and  vendors;  the  impact  to  the 
financial services and banking industry; and the impact to the economy as a whole as well as the effect of actions 
taken,  or  that  may  yet  be  taken,  or  inaction  by  governmental  authorities  to  contain  the  outbreak  or  to  mitigate  its 
impact  (both  economic  and  health-related).  COVID-19  has  negatively  affected,  and  is  expected  to  continue  to 
negatively affect, our business, financial position and operating results. In light of the uncertainties and continuing 
developments discussed herein, the ultimate adverse impact of COVID-19 cannot be reliably estimated at this time, 
but it has been and is expected to continue to be material. The longer-term potential impact on our business could 
depend  to  a  large  extent  on  future  developments  and  actions  taken  by  authorities  and  other  entities  to  contain 
COVID-19  and  its  economic  impact.  Furthermore,  the  sustainability  of  the  economic  recovery  observed  in  2021 
remains unclear and significant volatility could continue for a prolonged period as the potential exists for additional 
variants  of  COVID-19,  including  the  recent  Omicron  variant,  to  impede  the  global  economic  recovery  and 
exacerbate geographic differences in the spread of, and response to, COVID-19.

Impact on our Operations. In 2020, the State of Texas and many other jurisdictions declared health emergencies. 
The  resulting  closures  and/or  limited  operations  of  non-essential  businesses  and  related  economic  disruption 
impacted our operations as well as the operations of our customers. Financial services were identified as a Critical 
Infrastructure  Sector  by  the  Department  of  Homeland  Security.  Accordingly,  our  business  remained  open  and  we 
implemented our Business Continuity and Health Emergency Response plans to address the issues arising as a result 
of COVID-19 and to facilitate the continued delivery of essential services while maintaining a high level of safety 
for  our  customers  as  well  as  our  employees.  Nonetheless,  as  the  COVID-19  pandemic  continues  to  be  on-going, 
there continues to be uncertainties related to its magnitude, duration and persistent effects. This is particularly the 
case  with  the  emergence,  contagiousness  and  threat  of  new  and  different  strains  of  the  virus  as  well  as  the 
availability,  acceptance  and  effectiveness  of  vaccines.  As  such,  the  COVID-19  pandemic  could  still,  among  other 
things, greatly affect our routine and essential operations due to staff absenteeism, particularly among key personnel; 
result  in  limited  access  to  or  closures  of  our  branch  facilities  and  other  physical  offices;  exacerbate  operational, 
technical or security-related risks arising from a remote workforce; and result in adverse government or regulatory 
agency orders. Additionally, we are experiencing an increasingly competitive labor market due to an on-going labor 
shortage which has impacted and could continue to impact our ability to staff open positions and/or retain existing 
employees  and  has  resulted  in  and  could  continue  to  result  in  an  increase  in  our  staffing  costs.  The  business  and 
operations of our third-party service providers, many of whom perform critical services for our business, could also 

37

be significantly impacted by many of these same issues, which in turn could impact us. As a result, we continue to 
be unable to fully assess or predict the extent of the effects of COVID-19 on our operations as the ultimate impact 
will depend on factors that are currently unknown and/or beyond our control.

Impact on our Financial Position and Results of Operations. Our financial position and results of operations are 
particularly  susceptible  to  the  ability  of  our  loan  customers  to  meet  loan  obligations,  the  availability  of  our 
workforce, the availability of our vendors and the decline in the value of assets held by us. While its effects continue 
to  be  on-going,  during  2020  and  to  a  lesser  extent  in  2021,  the  COVID-19  pandemic  resulted  in  a  significant 
decrease  in  commercial  activity  throughout  the  State  of  Texas  as  well  as  nationally.  This  decrease  in  commercial 
activity caused and, in light of new and different strains of the virus, may yet further cause our customers (including 
affected  businesses  and  individuals),  vendors  and  counterparties  to  be  unable  to  meet  existing  payment  or  other 
obligations to us. The national public health crisis arising from the COVID-19 pandemic (and public expectations 
about  it),  combined  with  other  factors,  including,  but  not  limited  to,  inflation,  labor  shortages,  supply  chain 
disruption  and  further  oil  price  volatility,  could,  despite  improvements  in  2021,  again  destabilize  the  financial 
markets  and  geographies  in  which  we  operate.  The  resulting  economic  pressure  on  consumers  and  uncertainty 
regarding  the  sustainability  of  any  economic  improvements  could  further  impact  the  creditworthiness  of  potential 
and  current  borrowers.  Borrower  loan  defaults  that  adversely  affect  our  earnings  correlate  with  deteriorating 
economic  conditions,  which,  in  turn,  are  likely  to  impact  our  borrowers'  creditworthiness  and  our  ability  to  make 
loans. See further information related to the risk exposure of our loan portfolio under the sections captioned “Loans” 
and “Allowance for Credit Losses” elsewhere in this discussion.

In addition, the economic pressures and uncertainties arising from the COVID-19 pandemic have resulted in and 
may  continue  to  result  in  specific  changes  in  consumer  and  business  spending  and  borrowing  and  saving  habits, 
affecting  the  demand  for  loans  and  other  products  and  services  we  offer.  Consumers  affected  by  COVID-19  may 
continue  to  demonstrate  changed  behavior  even  after  the  crisis  is  over.  For  example,  consumers  may  decrease 
discretionary  spending  on  a  permanent  or  long-term  basis  and  certain  industries  may  take  longer  to  recover 
(particularly  those  that  rely  on  travel  or  large  gatherings)  as  consumers  may  be  hesitant  to  return  to  full  social 
interaction.  We  lend  to  customers  operating  in  such  industries  including  energy,  hotels/lodging,  restaurants, 
entertainment and commercial real estate, among others, that have been significantly impacted by COVID-19 and 
we are continuing to monitor these customers closely. Additionally, the temporary closures of bank branches in 2020 
and  the  safety  precautions  implemented  at  re-opened  branches  could  result  in  consumers  becoming  more 
comfortable  with  technology  and  devaluing  face-to-face  interaction.  Our  business  is  relationship  driven  and  such 
changes could necessitate changes to our business practices to accommodate changing consumer behaviors.

Legislative and Regulatory Actions. Actions taken by the federal government and the Federal Reserve and other 
bank regulatory agencies to mitigate the economic effects of COVID-19 have impacted our financial position and 
results of operations. These actions are further discussed below.

During  2020,  in  an  effort  to  provide  monetary  stimulus  to  counteract  the  economic  disruption  caused  by 

COVID-19, the Federal Reserve: 

•

•

•

•

•

•

Expanded reverse repo operations, adding liquidity to the banking system.

Restarted quantitative easing.

Lowered the interest rate at the discount window by 1.5% to 0.25%.

Reduced reserve requirement ratios to zero percent.

Encouraged banks to use their capital and liquidity buffers to lend.

Introduced and expanded several new temporary programs to help preserve market liquidity.

In  2020,  the  U.S.  government  enacted  certain  fiscal  stimulus  measures  in  several  phases  to  counteract  the 
economic disruption caused by the COVID-19. The Phase 1 legislation, the Coronavirus Preparedness and Response 
Supplemental Appropriations Act, was enacted on March 6, 2020 and, among other things, authorized funding for 
research and development of vaccines and allocated money to state and local governments to aid containment and 
response measures. The Phase 2 legislation, the Families First Coronavirus Response Act, was enacted on March 18, 
2020  and  provided  for  paid  sick/medical  leave,  established  no-cost  coverage  for  coronavirus  testing,  expanded 
unemployment  benefits,  expanded  food  assistance,  and  provided  additional  funding  to  states  for  the  ongoing 
economic  consequences  of  the  pandemic,  among  other  provisions.  The  Phase  3  legislation,  the  Coronavirus  Aid, 
Relief, and Economic Security Act (the “CARES Act”), was enacted on March 27, 2020. Among other provisions, 
the CARES Act (i) authorized the Secretary of the Treasury to make loans, loan guarantees and other investments, 

38

up  to  $500  billion,  for  assistance  to  eligible  businesses,  States  and  municipalities  with  limited,  targeted  relief  for 
passenger  air  carriers,  cargo  air  carriers,  and  businesses  critical  to  maintaining  national  security,  (ii)  created  a 
$349  billion  loan  program  called  the  Paycheck  Protection  Program  (the  “PPP”)  for  loans  to  small  businesses  for, 
among  other  things,  payroll,  group  health  care  benefit  costs  and  qualifying  mortgage,  rent  and  utility  payments, 
(iii)  provided  certain  credits  against  the  2020  personal  income  tax  for  eligible  individuals  and  their  dependents, 
(iv) expanded eligibility for unemployment insurance and provides eligible recipients with an additional $600 per 
week  on  top  of  the  unemployment  amount  determined  by  each  State  and  (v)  expanded  tele-health  services  in 
Medicare.  The  Phase  3.5  legislation,  the  Paycheck  Protection  Program  and  Healthcare  Enhancement  Act  of  2020 
(the  “PPPHE  Act”),  was  enacted  on  April  24,  2020.  Among  other  things,  the  PPPHE  Act  provided  an  additional 
$310 billion of funding for the PPP. The Paycheck Protection Program Flexibility Act of 2020” (the “PPPF Act”) 
was  enacted  in  June  2020  to  modify  certain  provisions  of  the  PPP  including,  among  other  things,  establishing  a 
minimum maturity of five years for all loans made after the enactment of the PPPF Act and permitted an extension 
of the maturity of existing loans to five years if the borrower and lender agree. 

In  December  2020,  the  Bipartisan-Bicameral  Omnibus  COVID  Relief  Deal,  included  as  a  component  of 
appropriations  legislation,  was  enacted  to  provide  economic  stimulus  to  individuals  and  businesses  in  further 
response  to  the  economic  distress  caused  by  the  COVID-19  pandemic.  Among  other  things,  the  legislation 
(i)  authorized  payments  of  $600  for  individuals  making  up  to  $75,000  per  year,  (ii)  extended  the  timeframe  for 
enhanced unemployment benefits and (iii) authorized approximately $325 billion for small business relief, including 
approximately  $284  billion  for  a  second  round  of  PPP  loans  and  a  new  simplified  forgiveness  procedure  for  PPP 
loans of $150,000 or less. 

During the first quarter of 2021, President Biden signed a number of executive orders relating to stimulus and 
relief  measures.  These  orders  included,  among  other  things,  (i)  an  extension,  through  March  31,  2021,  of  the 
moratorium on evictions and foreclosures, (ii) an extension, through September 30, 2021, of the deferral of federal 
student loan payments and interest and (iii) an extension, through June 30, 2021, of certain mortgage forbearance 
programs and guidelines. 

On  March  11  2021,  the  American  Rescue  Plan  Act  of  2021  (the  “ARP  Act”)  was  enacted,  implementing  a 
$1.9  trillion  package  of  stimulus  and  relief  proposals.  Among  other  things,  the  ARP  Act  provided  (i)  additional 
funding for the PPP program and an expansion of the program for the benefit of certain nonprofits, (ii) funding for 
the  Small  Business  Administration  (“SBA”)  to  make  targeted  grants  for  restaurants  and  similar  establishments, 
(iii)  direct  cash  payments  of  up  to  $1,400  to  individuals,  subject  to  income  provisions,  (iv)  an  increase  in  the 
maximum  annual  Child  Tax  Credit,  subject  to  income  limitation  provisions,  (v)  $300  a  week  in  expanded 
unemployment insurance lasting through September 6, 2021 and made $10,200 in unemployment benefits tax free 
for households, subject to income limitation provisions, (vi) tax relief making any student loan forgiveness incurred 
between December 31, 2020, and January 1, 2026 non-taxable income, and (vii) funding to support state and local 
governments; K-12 schools and higher education; the Centers for Disease Control; public transit; rental assistance; 
child care; and airline industry workers. 

On  March  27,  2021,  the  COVID-19  Bankruptcy  Relief  Extension  Act  of  2021  was  enacted,  extending  the 
bankruptcy relief provisions enacted in the CARES Act of 2020 bill until March 27, 2022. These provisions provide 
financially  distressed  small  businesses  and  individuals  greater  access  to  bankruptcy  relief.  We  are  continuing  to 
monitor the potential development of additional legislation and further actions taken by the U.S. government.

The above mentioned significant fiscal stimulus and monetary policy actions of the U.S. government and Federal 
Reserve have been contributing factors to an inflationary surge during most of 2021. As a result, in December 2021, 
the Federal Reserve released projections related to the target range for the federal funds rate that imply, while there 
can be no such assurance that any increases in the federal funds rate will occur, three 25 basis point increases in the 
federal funds rate in 2022, followed by three in 2023 and two in 2024 as further discussed in the section captioned 
“Net Interest Income” elsewhere in this discussion.

Banks and bank holding companies have been particularly impacted by the COVID-19 pandemic as a result of 
disruption  and  volatility  in  the  global  capital  markets.  We  are  closely  monitoring  the  potential  for  new  laws  and 
regulations impacting lending and funding practices as well as capital and liquidity standards. Such changes could 
require us to maintain significantly more capital, with common equity as a more predominant component, or manage 
the composition of our assets and liabilities to comply with formulaic liquidity requirements.

39

Application of Critical Accounting Policies and Accounting Estimates

We  follow  accounting  and  reporting  policies  that  conform,  in  all  material  respects,  to  accounting  principles 
generally  accepted  in  the  United  States  and  to  general  practices  within  the  financial  services  industry.  The 
preparation of financial statements in conformity with accounting principles generally accepted in the United States 
requires management to make estimates and assumptions that affect the amounts reported in the financial statements 
and  accompanying  notes.  While  we  base  estimates  on  historical  experience,  current  information  and  other  factors 
deemed to be relevant, actual results could differ from those estimates.

We consider accounting estimates to be critical to reported financial results if (i) the accounting estimate requires 
management  to  make  assumptions  about  matters  that  are  highly  uncertain  and  (ii)  different  estimates  that 
management  reasonably  could  have  used  for  the  accounting  estimate  in  the  current  period,  or  changes  in  the 
accounting estimate that are reasonably likely to occur from period to period, could have a material impact on our 
financial statements.

Accounting  policies  related  to  the  allowance  for  credit  losses  on  financial  instruments  including  loans  and  off-
balance-sheet  credit  exposures  are  considered  to  be  critical  as  these  policies  involve  considerable  subjective 
judgment and estimation by management. As discussed in Note 1 - Summary of Significant Accounting Policies, our 
policies related to allowances for credit losses changed on January 1, 2020 in connection with the adoption of a new 
accounting  standard  update  as  codified  in  Accounting  Standards  Codification  (“ASC”)  Topic  326  (“ASC  326”) 
Financial Instruments - Credit Losses. In the case of loans, the allowance for credit losses is a contra-asset valuation 
account, calculated in accordance with ASC 326, that is deducted from the amortized cost basis of loans to present 
the net amount expected to be collected. 

In the case of off-balance-sheet credit exposures, the allowance for credit losses is a liability account, calculated 
in  accordance  with  ASC  326,  reported  as  a  component  of  accrued  interest  payable  and  other  liabilities  in  our 
consolidated  balance  sheets.  The  amount  of  each  allowance  account  represents  management's  best  estimate  of 
current  expected  credit  losses  on  these  financial  instruments  considering  available  information,  from  internal  and 
external sources, relevant to assessing exposure to credit loss over the contractual term of the instrument. Relevant 
available  information  includes  historical  credit  loss  experience,  current  conditions  and  reasonable  and  supportable 
forecasts.  While  historical  credit  loss  experience  provides  the  basis  for  the  estimation  of  expected  credit  losses, 
adjustments  to  historical  loss  information  may  be  made  for  differences  in  current  portfolio-specific  risk 
characteristics, environmental conditions or other relevant factors. While management utilizes its best judgment and 
information  available,  the  ultimate  adequacy  of  our  allowance  accounts  is  dependent  upon  a  variety  of  factors 
beyond our control, including the performance of our portfolios, the economy, changes in interest rates and the view 
of the regulatory authorities toward classification of assets. See the section captioned “Allowance for Credit Losses” 
elsewhere in this discussion as well as Note 1 - Summary of Significant Accounting Policies and Note 3 - Loans in 
the  notes  to  consolidated  financial  statements  included  in  Item  8.  Financial  Statements  and  Supplementary  Data 
elsewhere in this report for further details of the risk factors considered by management in estimating the necessary 
level of the allowance for credit losses.

Overview

The following discussion and analysis presents the more significant factors that affected our financial condition as 
of December 31, 2021 and 2020 and results of operations for each of the years then ended. Refer to Management’s 
Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 
10-K  filed  with  the  SEC  on  February  5,  2021  (the  “2020  Form  10-K”)  for  a  discussion  and  analysis  of  the  more 
significant factors that affected periods prior to 2020.

Certain reclassifications have been made to make prior periods comparable. This discussion and analysis should 
be  read  in  conjunction  with  our  consolidated  financial  statements,  notes  thereto  and  other  financial  information 
appearing  elsewhere  in  this  report.  From  time  to  time,  we  have  acquired  various  small  businesses  through  our 
insurance subsidiary. None of these acquisitions had a significant impact on our financial statements. We account for 
acquisitions using the acquisition method, and as such, the results of operations of acquired companies are included 
from the date of acquisition.

Taxable-equivalent  adjustments  are  the  result  of  increasing  income  from  tax-free  loans  and  investments  by  an 
amount  equal  to  the  taxes  that  would  be  paid  if  the  income  were  fully  taxable,  thus  making  tax-exempt  yields 
comparable to taxable asset yields. Taxable equivalent adjustments were based upon a 21% income tax rate.

Dollar amounts in tables are stated in thousands, except for per share amounts.

Net income available to common shareholders increased $112.3 million for 2021 compared to 2020. The increase 
was  primarily  the  result  of  a  $241.2  million  decrease  in  credit  loss  expense  and  an  $8.9  million  increase  in  net 
interest  income  partly  offset  by  a  $78.7  million  decrease  in  non-interest  income,  a  $33.1  million  increase  in  non-
interest expense and a $26.3 million increase in income tax expense. Credit loss expense during 2020 was impacted 
by both our adoption of a new credit loss accounting standard and the adverse events impacting our loan portfolio, 
including those arising from the COVID-19 pandemic and the significant volatility in oil prices. Non-interest income 
during 2020 was impacted by a $109.0 million net gain on securities transactions during the first quarter. Net income 
available to common shareholders during 2020 was also impacted by the reclassification of $5.5 million of issuance 
costs associated with our Series A preferred stock to retained earnings upon redemption of the Series A preferred 
stock.

Details of the changes in the various components of net income are further discussed below.

Net Interest Income

Net interest income is the difference between interest income on earning assets, such as loans and securities, and 
interest  expense  on  liabilities,  such  as  deposits  and  borrowings,  which  are  used  to  fund  those  assets.  Net  interest 
income is our largest source of revenue, representing 71.8% of total revenue during 2021. Net interest margin is the 
ratio of taxable-equivalent net interest income to average earning assets for the period. The level of interest rates and 
the  volume  and  mix  of  earning  assets  and  interest-bearing  liabilities  impact  net  interest  income  and  net  interest 
margin. 

The Federal Reserve influences the general market rates of interest, including the deposit and loan rates offered 
by many financial institutions. Our loan portfolio is significantly affected by changes in the prime interest rate. The 
prime rate began 2019 at 5.50% and decreased 50 basis points during the third quarter of 2019 (25 basis points in 
each  of  August  and  September)  and  25  basis  points  in  October  2019  to  end  the  year  at  4.75%.  During  2020,  the 
prime rate decreased 150 basis points in March to 3.25% where it remained through December 31, 2021. Our loan 
portfolio  is  also  significantly  impacted,  by  changes  in  the  London  Interbank  Offered  Rate  (“LIBOR”).  At 
December 31, 2021, the one-month and three-month U.S. dollar LIBOR rates were 0.10% and 0.21%, respectively, 
while  at  December  31,  2020,  the  one-month  and  three-month  U.S.  dollar  LIBOR  rates  were  0.14%  and  0.24% 
respectively, and at December 31, 2019, the one-month and three-month U.S. dollar LIBOR rates were 1.76% and 
1.90%  respectively.  We  discontinued  originating  LIBOR-based  loans  effective  December  31,  2021  and  will 
negotiate  loans  using  our  preferred  replacement  index,  the  American  Interbank  Offered  Rate  (“AMERIBOR”),  a 
benchmark  developed  by  the  American  Financial  Exchange,  the  Secured  Overnight  Financing  Rate  (“SOFR”)  or 
(“BSBY”),  a  benchmark  developed  by  Bloomberg  Index  Services.  For  our  currently  outstanding  LIBOR-based 
loans, the timing and manner in which each customer’s contract transitions to AMERIBOR, SOFR or BSBY will 
vary on a case-by-case basis. We expect to complete all transitions by the first quarter of 2023.

The  target  range  for  the  federal  funds  rate,  which  is  the  cost  of  immediately  available  overnight  funds,  began 
2019 at 2.25% to 2.50% and decreased 50 basis points during the third quarter of 2019 (25 basis points in each of 
August and September) and 25 basis points in October 2019 to end the year at 1.50% to 1.75%. During 2020, the 
target  range  for  the  federal  funds  rate  decreased  150  basis  points  in  March  to  zero  to  0.25%  where  it  remained 
through December 31, 2021. The decrease in the target range for the federal funds rate in March 2020 was largely an 
emergency  measure  by  the  Federal  Reserve  aimed  at  blunting  the  economic  impact  of  COVID-19.  In  December 
2021, the Federal Reserve released projections whereby the midpoint of the projected appropriate target range for 
the federal funds rate would rise to 0.9% by the end of 2022, to 1.6% by the end of 2023 and to 2.1% by the end of 
2024. While there can be no such assurance that any increases in the federal funds rate will occur, these projections 
imply three 25 basis point increases in the federal funds rate in 2022, followed by three in 2023 and two in 2024. 

We  are  primarily  funded  by  core  deposits,  with  non-interest-bearing  demand  deposits  historically  being  a 
significant source of funds. This lower-cost funding base is expected to have a positive impact on our net interest 
income  and  net  interest  margin  in  a  rising  interest  rate  environment.  See  Item  7A.  Quantitative  and  Qualitative 
Disclosures  About  Market  Risk  elsewhere  in  this  report  for  information  about  our  sensitivity  to  interest  rates. 
Further analysis of the components of our net interest margin is presented below.

The following table presents an analysis of net interest income and net interest spread for the periods indicated, 
including  average  outstanding  balances  for  each  major  category  of  interest-earning  assets  and  interest-bearing 
liabilities,  the  interest  earned  or  paid  on  such  amounts,  and  the  average  rate  earned  or  paid  on  such  assets  or 
liabilities, respectively. The table also sets forth the net interest margin on average total interest-earning assets for 
the  same  periods.  For  these  computations:  (i)  average  balances  are  presented  on  a  daily  average  basis, 
(ii) information is shown on a taxable-equivalent basis assuming a 21% tax rate, (iii) average loans include loans on 
non-accrual  status,  and  (iv)  average  securities  include  unrealized  gains  and  losses  on  securities  available  for  sale, 
while yields are based on average amortized cost.

The following table presents the changes in taxable-equivalent net interest income and identifies the changes due 
to differences in the average volume of earning assets and interest-bearing liabilities and the changes due to changes 
in the average interest rate on those assets and liabilities. The changes in net interest income due to changes in both 
average volume and average interest rate have been allocated to the average volume change or the average interest 
rate change in proportion to the absolute amounts of the change in each. The comparisons between years includes an 
additional change factor that shows the effect of the difference in the number of days (due to leap year in 2020) in 
each  period  for  assets  and  liabilities  that  accrue  interest  based  upon  the  actual  number  of  days  in  the  period,  as

Taxable-equivalent  net  interest  income  for  2021  increased  $6.4  million,  or  0.6%,  compared  to  2020.  Taxable-
equivalent  net  interest  income  for  2021  included  365  days  compared  to  366  days  for  2020  as  a  result  of  the  leap 
year.  The  additional  day  added  approximately  $1.8  million  to  taxable-equivalent  net  interest  income  during  2020. 
Excluding the impact of the additional day results in an effective increase in taxable-equivalent net interest income 
of  approximately  $8.2  million  during  2021.  The  taxable-equivalent  net  interest  margin  decreased  56  basis  points 
from 3.09% during 2020 to 2.53% during 2021. 

The  increase  in  taxable-equivalent  net  interest  income  during  2021  was  primarily  related  to  decreases  in  the 
average costs of interest-bearing deposit liabilities and other borrowed funds combined with increases in the average 
volumes  of  interest-bearing  deposits  (primarily  amounts  held  by  us  in  an  interest-bearing  account  at  the  Federal 
Reserve) and taxable securities and an increase in the average taxable-equivalent yield on loans. The positive impact 
of these items was partly offset by decreases in the average volumes of loans and tax-exempt securities and increases 
in the average volumes of interest-bearing deposit liabilities and repurchase agreements combined with decreases in 
the average yields on taxable and tax-exempt securities and interest-bearing deposits (primarily amounts held by us 
in an interest-bearing account at the Federal Reserve). The decrease in taxable-equivalent net interest margin during 
2021 was primarily related to an increase in the relative proportion of average interest-bearing deposits (primarily 
amounts  held  by  us  in  an  interest-bearing  account  at  the  Federal  Reserve)  to  average  total  interest-earning  assets 
combined  with  the  aforementioned  decreases  in  market  interest  rates.  Interest-bearing  deposits  made  up 
approximately 31.3% of average interest-earning assets during 2021 compared to approximately 15.0% in 2020.

The average volume of interest-earning assets for 2021 increased $7.9 billion, or 22.5%, compared to 2020. The 
increase  in  the  average  volume  of  interest-earning  assets  during  2021  included  a  $8.2  billion  increase  in  average 
interest-bearing deposits (primarily amounts held by us in an interest-bearing account at the Federal Reserve) and a 
$372.2 million increase in average taxable securities partly offset by a $394.8 million decrease in average loans (of

average tax-exempt securities, a $64.0 million decrease in average federal funds sold and a $14.3 million decrease in 
average resell agreements.

The average yield on interest-earning assets decreased 64 basis points from 3.22% during 2020 to 2.58% during 
2021  while  the  average  rate  paid  on  interest-bearing  liabilities  decreased  13  basis  points  from  0.23%  in  2020  to 
0.10%  in  2021.  The  average  taxable-equivalent  yields  on  interest-earning  assets  and  the  average  rate  paid  on 
interest-bearing  liabilities  were  primarily  impacted  by  the  aforementioned  changes  in  market  interest  rates  and 
changes in the volume and relative mix of interest-earning assets and interest-bearing liabilities. 

The average taxable-equivalent yield on loans increased 6 basis points from 3.99% during 2020 to 4.05% during 
2021. The average taxable-equivalent yield on loans during 2021 was positively impacted by higher average yields 
on PPP loans but negatively impacted by lower average market interest rates compared to 2020. The average volume 
of loans decreased $394.8 million, or 2.3%, in 2021 compared to 2020. The decrease in average loans was primarily 
due to an increase in the average volume of PPP loans forgiven by the SBA during 2021 compared to 2020. Loans 
made up approximately 38.8% of average interest-earning assets during 2021 compared to 48.7% during 2020. 

In April 2020, we began originating loans to qualified small businesses under the PPP administered by the SBA 
under  the  provisions  of  the  CARES  Act.  In  2020,  we  funded  $3.3  billion  of  PPP  loans  of  which  approximately 
$3.2 billion were funded during the second quarter of 2020. As of December 31, 2021, approximately $3.2 billion of 
these 2020 originated PPP loans have been forgiven by the SBA or repaid by the customer. During 2021, we funded 
an  additional  $1.4  billion  of  PPP  loans,  most  of  which  was  during  the  first  quarter.  As  of  December  31,  2021, 
approximately  $1.0  billion  of  these  2021  originated  PPP  loans  have  been  forgiven  by  the  SBA  or  repaid  by  the 
customer. During 2021 and 2020, we recognized $97.3 million and $59.5 million, respectively, in PPP loan related 
deferred  processing  fees  (net  of  amortization  of  related  deferred  origination  costs)  as  a  yield  adjustment  and  this 
amount is included in interest income on loans. As a result of the inclusion of these net fees in interest income, the 
average  yields  on  PPP  loans  were  6.26%  and  3.78%  during  2021  and  2020,  respectively,  compared  to  the  stated 
interest rate of 1.0% on these loans. The increase in the average yield on PPP Loans was impacted by a decrease in 
the  average  expected  lives  of  the  PPP  loans  funded  in  2021  compared  to  2020.  Furthermore,  the  average  fee 
percentage  for  2021  originations  was  higher  due  to  a  smaller  average  loan  size  relative  to  2020.  In  return  for 
processing and booking a PPP loan, the SBA paid lenders a processing fee tiered by the size of the loan (5% for 
loans of not more than $350 thousand; 3% for loans of more than $350 thousand and less than $2 million; and 1% 
for  loans  of  at  least  $2  million).  For  PPP  loans  funded  through  December  31,  2021,  we  expect  to  recognize 
additional PPP loan related deferred processing fees (net of deferred origination costs) totaling approximately $2.8 
million as a yield adjustment over the remaining expected lives of these loans. We expect to recognize all of this 
amount in 2022.

The average taxable-equivalent yield on securities was 3.29% during 2021, decreasing 17 basis points compared 
to 3.46% during 2020 and was negatively impacted by a decrease in the relative proportion of higher-yielding tax-
exempt  securities  to  total  securities.  The  average  yield  on  taxable  securities  was  1.97%  during  2021  compared  to 
2.27% during 2020, decreasing 30 basis points, while the average yield on tax exempt securities was 4.06% during 
2021  compared  to  4.08%  during  2020,  decreasing  2  basis  points.  Tax  exempt  securities  made  up  approximately 
64.2%  of  total  average  securities  during  2021,  compared  to  66.6%  during  2020.  The  average  volume  of  total 
securities  increased  $193.6  million,  or  1.5%,  during  2021  compared  to  2020.  Securities  made  up  approximately 
29.8% of average interest-earning assets in 2021 compared to 36.0% in 2020. The decrease was primarily related to 
an  increase  in  the  relative  proportion  of  interest-earning  assets  invested  in  interest-bearing  deposits  (primarily 
amounts held by us in an interest-bearing account at the Federal Reserve).

Average  interest-bearing  deposits  (primarily  amounts  held  by  us  in  an  interest-bearing  account  at  the  Federal 
Reserve),  during  2021  increased  $8.2  billion,  or  155.2%,  compared  to  2020.  Interest-bearing  deposits  made  up 
approximately 31.3% of average interest-earning assets during 2021 compared to approximately 15.0% in 2020. The 
increase  in  the  average  volume  of  interest-bearing  deposits  (primarily  amounts  held  by  us  in  an  interest-bearing 
account at the Federal Reserve) during 2021 was primarily due to an increase in the average volume of customer 
deposits and, to a lesser extent, repurchase agreements. The average yield on interest-bearing deposits was 0.13% 
during  2021  and  0.24%  during  2020.  The  average  yields  on  interest-bearing  deposits  during  2021  and  2020  were 
negatively impacted by a decrease in the interest rate paid on excess reserves held at the Federal Reserve to 0.10% 
during March 2020, although this rate ultimately increased 5 basis points to 0.15% in June 2021.

Average  federal  funds  sold  and  resell  agreements  during  2021  decreased  $64.0  million,  or  81.2%,  and  $14.3 
million, or 68.4%, respectively compared to 2020. Federal funds sold and resell agreements were not a significant 
component of interest-earning assets during the comparable periods. The average yields on federal funds sold and 
resell  agreements  were  0.21%  and  0.24%,  respectively,  during  2021  compared  to  0.92%  and  0.82%,  respectively, 
during  2020.  The  average  yields  on  federal  funds  sold  and  resell  agreements  were  negatively  impacted  by  lower 
average market interest rates during 2021 compared to 2020.

The  average  rate  paid  on  interest-bearing  liabilities  was  0.10%  during  2021,  decreasing  13  basis  points  from 
0.23% during 2020. Average deposits increased $7.0 billion, or 22.4%, in 2021 compared to 2020. Average interest-
bearing  deposits  increased  $3.9  billion  in  2021  compared  to  2020,  while  average  non-interest-bearing  deposits 
increased  $3.1  billion  in  2021  compared  to  2020.  The  ratio  of  average  interest-bearing  deposits  to  total  average 
deposits  was  56.7%  in  2021  compared  to  56.9%  in  2020.  The  average  cost  of  deposits  is  primarily  impacted  by 
changes in market interest rates as well as changes in the volume and relative mix of interest-bearing deposits. The 
average rate paid on interest-bearing deposits and total deposits was 0.07% and 0.04% in 2021 compared to 0.18% 
and 0.10% in 2020. The average cost of deposits during 2021 and 2020 was impacted by decreases in the interest 
rates we pay on most of our interest-bearing deposit products as a result of the aforementioned decreases in market 
interest rates. 

In April 2020, we borrowed an aggregate $1.3 billion from the Federal Home Loan Bank (“FHLB”) to provide 
additional liquidity in light of economic uncertainty and our significant PPP lending volume. These advances were 
subsequently paid-off in May 2020 as we determined additional liquidity resources were not necessary.

Our  taxable-equivalent  net  interest  spread,  which  represents  the  difference  between  the  average  rate  earned  on 
earning  assets  and  the  average  rate  paid  on  interest-bearing  liabilities,  was  2.48%  in  2021  compared  to  2.99%  in 
2020. The net interest spread, as well as the net interest margin, will be impacted by future changes in short-term 
and  long-term  interest  rate  levels,  as  well  as  the  impact  from  the  competitive  environment.  A  discussion  of  the 
effects  of  changing  interest  rates  on  net  interest  income  is  set  forth  in  Item  7A.  Quantitative  and  Qualitative 
Disclosures About Market Risk elsewhere in this report.

Our  hedging  policies  permit  the  use  of  various  derivative  financial  instruments,  including  interest  rate  swaps, 
swaptions, caps and floors, to manage exposure to changes in interest rates. Details of our derivatives and hedging 
activities  are  set  forth  in  Note  15  -  Derivative  Financial  Instruments  in  the  accompanying  notes  to  consolidated 
financial statements elsewhere in this report. Information regarding the impact of fluctuations in interest rates on our 
derivative financial instruments is set forth in Item 7A. Quantitative and Qualitative Disclosures About Market Risk 
elsewhere in this report.

Credit Loss Expense

Credit  loss  expense  is  determined  by  management  as  the  amount  to  be  added  to  the  allowance  for  credit  loss 
accounts for various types of financial instruments including loans, securities and off-balance-sheet credit exposure 
after net charge-offs have been deducted to bring the allowance to a level which, in management’s best estimate, is 
necessary to absorb expected credit losses over the lives of the respective financial instruments. 

The components of credit loss expense were as follows.

Credit loss expense in 2019 was calculated under the prior incurred loss accounting methodology. Furthermore, 
credit loss expense related to off-balance-sheet credit exposures was reported as a component of other non-interest 
expense prior to 2020. Such amounts have been reclassified to credit loss expense to make prior periods comparable 
to the current presentation. See the section captioned “Allowance for Credit Losses” elsewhere in this discussion for 
further analysis of credit loss expense related to loans and off-balance-sheet credit exposures.

Non-Interest Income

Total  non-interest  income  for  2021  decreased  $78.7  million,  or  16.9%,  compared  to  2020.  Excluding  $69 
thousand and $109.0 million in net gains on securities transactions during 2021 and 2020, respectively, total non-
interest income increased $30.2 million, or 8.5%, during 2021. Changes in the various components of non-interest 
income are discussed in more detail below.

Trust and Investment Management Fees. Trust and investment management fee income for 2021 increased $19.7 
million, or 15.3%, compared to 2020. Investment management fees are the most significant component of trust and 
investment management fees, making up approximately 82.3% and 83.6% of total trust and investment management 
fees  in  2021  and  2020,  respectively.  The  increase  in  trust  and  investment  management  fees  during  2021  was 
primarily  due  to  increases  in  investment  management  fees  (up  $14.6  million,  or  13.5%),  oil  and  gas  fees  (up 
$3.1 million), estate fees (up $1.5 million) and custody fees (up $580 thousand). Investment management fees and 
other  custodial  account  fees  are  generally  based  on  the  market  value  of  assets  within  an  account  and  are  thus 
impacted by volatility in the equity and bond markets. The increases in investment management fees and custody 
fees during 2021 were primarily related to higher average equity valuations as well as increases in the number of 
accounts. Oil and gas fees during 2021 were impacted by increases in oil and gas prices. The increase in estate fees 
was primarily related to an increase in the aggregate value of estates settled.

At December 31, 2021, trust assets, including both managed assets and custody assets, were primarily composed 
of equity securities (46.9% of trust assets), fixed income securities (31.1% of trust assets), alternative investments 
(6.6% of assets) and cash equivalents (9.9% of trust assets). The estimated fair value of trust assets was $43.3 billion 
(including managed assets of $19.1 billion and custody assets of $24.2 billion) at December 31, 2021 compared to 
$38.6 billion (including managed assets of $16.9 billion and custody assets of $21.7 billion) at December 31, 2020.

Service Charges on Deposit Accounts. Service charges on deposit accounts for 2021 increased $2.4 million, or 
3.0%, compared to 2020. The increase was primarily related to an increase in commercial service charges (up $3.7 
million)  partly  offset  by  a  decrease  in  overdraft  charges  on  consumer  accounts  (down  $1.8  million).  Commercial 
service  charges  during  2021  were  impacted  by  an  increase  in  the  volume  of  billable  services  relative  to  2020. 
Overdraft/insufficient  funds  charges  totaled  $30.7  million  ($23.9  million  consumer  and  $6.8  million  commercial) 
during  2021  compared  to  $32.3  million  ($25.8  million  consumer  and  $6.5  million  commercial)  during  2020.  The 
decreases  in  consumer  overdraft/insufficient  funds  charges  during  2021  was  primarily  related  to  a  decrease  in  the 
volume  of  fee  assessed  overdrafts  relative  to  2020.  Furthermore,  in  April  2021,  we  implemented  a  new  overdraft 
grace feature for certain consumer demand deposit accounts whereby no fees will be assessed on overdrafts of $100 
or  less,  subject  to  certain  qualifying  conditions  such  as  a  minimum  direct  deposit.  This  new  feature  reduced 
overdraft charges on consumer accounts by approximately $3.2 million during 2021. The impact on future quarters 
will depend on future overdraft volumes.

Insurance  Commissions  and  Fees.  Insurance  commissions  and  fees  for  2021  increased  $1.2  million,  or  2.5%, 
compared to 2020. The increase was related to increases in contingent income (up $829 thousand) and commission 
income (up $406 thousand). Contingent income totaled $4.5 million in 2021 and $3.7 million in 2020. Contingent 
income primarily consists of amounts received from various property and casualty insurance carriers related to the 
loss  performance  of  insurance  policies  previously  placed.  These  performance  related  contingent  payments  are 
seasonal in nature and are mostly received during the first quarter of each year. This performance related contingent 
income  totaled  $3.2  million  in  2021  and  $2.5  million  in  2020.  The  increase  in  performance  related  contingent 
income during 2021 was related to growth within the portfolio combined with improvement in the loss performance 
of insurance policies previously placed. During the first quarter of 2021, a severe weather event in Texas resulted in 
a significant increase in property and casualty claims and losses. This deterioration in loss performance is expected 
to impact the determination of performance related contingent payments we receive in 2022; however, such impact 
is  not  determinable  at  this  time.  Contingent  income  also  includes  amounts  received  from  various  benefit  plan 
insurance companies related to the volume of business generated and/or the subsequent retention of such business. 
This benefit plan related contingent income totaled $1.3 million in 2021 and $1.2 million in 2020.

The increase in commission income was primarily related to increases in commercial lines property and casualty 
commissions and life insurance commissions partly offset by a decrease in benefit plan commissions. The increase 
in commercial lines property and casualty commissions were related to increased market rates while the increase in 
life  insurance  commissions  and  decrease  in  benefit  plan  commissions  were  related  to  fluctuations  in  business 
volumes.

Interchange and Card Transaction Fees. Interchange fees, or “swipe” fees, are charges that merchants pay to us 
and other card-issuing banks for processing electronic payment transactions. Interchange and card transaction fees 
consist  of  income  from  check  card  usage,  point  of  sale  income  from  PIN-based  debit  card  transactions  and  ATM 
service fees. Interchange and card transaction fees are reported net of related network costs. 

Net revenues from interchange and card transaction fees for 2021 increased $4.0 million, or 29.6%, compared to 
2020 primarily due to increased transaction volumes as well as the impact of new card products partly offset by an 
increase  in  network  costs.  Transaction  volumes  during  2020  were  impacted  by  the  onset  of  the  COVID-19 
pandemic. A comparison of gross and net interchange and card transaction fees for the reported periods is presented 
in the table below.

Federal Reserve rules applicable to financial institutions that have assets of $10 billion or more provide that the 
maximum permissible interchange fee for an electronic debit transaction is the sum of 21 cents per transaction and 
5 basis points multiplied by the value of the transaction. An upward adjustment of no more than 1 cent to an issuer's 
debit card interchange fee is allowed if the card issuer develops and implements policies and procedures reasonably 
designed  to  achieve  certain  fraud-prevention  standards.  The  Federal  Reserve  also  has  rules  governing  routing  and 
exclusivity that require issuers to offer two unaffiliated networks for routing transactions on each debit or prepaid 
product.

Other Charges, Commissions and Fees. Other charges, commissions and fees for 2021 increased $2.0 million, or 
5.8%, compared to 2020. The increase was primarily related to increases in income from the sale of mutual funds 
(up $3.0 million), merchant services rebates (up $978 thousand), funds transfer service charges (up $761 thousand) 
and income from the sale of annuities (up $571 thousand). These items were partly offset by a decrease in income 
from the placement of money market accounts (down $1.7 million), which was impacted by lower average market 
rates, and a decrease in fees on unused commitments (down $1.7 million), among other things.

Net  Gain/Loss  on  Securities  Transactions.  During  2021,  we  sold  certain  available-for-sale  securities  with 
amortized costs totaling $2.0 billion and realized a net gain of $69 thousand. These sales were primarily related to 
securities purchased during 2021 and subsequently sold in connection with our tax planning strategies related to the 
Texas  franchise  tax.  The  gross  proceeds  from  the  sales  of  these  securities  outside  of  Texas  are  included  in  total 
revenues/receipts  from  all  sources  reported  for  Texas  franchise  tax  purposes,  which  results  in  a  reduction  in  the 
overall percentage of revenues/receipts apportioned to Texas and subjected to taxation under the Texas franchise tax. 

During 2020, we sold certain available-for-sale securities with amortized costs totaling $1.0 billion and realized a 
net gain of $109.0 million. These sales included $483.1 million of residential mortgage-backed securities on which 
we  realized  a  net  gain  of  $1.9  million.  The  proceeds  from  these  sales  were  reinvested  into  other  residential 
mortgage-backed securities that had lower pre-payment rates. The sales also included $519.1 million of 30-year U.S 
Treasury  securities  on  which  we  realized  a  net  gain  of  $107.1  million.  These  U.S.  Treasury  securities  were 
purchased during the fourth quarter of 2019 to hedge, in effect, against falling interest rates. Prior to their sale, these 
securities  had  significant  unrealized  holding  gains  as  a  result  of  decreases  in  market  interest  rates  during  the  first 
quarter of 2020. We elected to sell these securities to provide liquidity and realize the gains. 

Other Non-Interest Income. Other non-interest income for 2021 increased $816 thousand, or 1.7%, compared to 
2020.  The  increase  in  other  non-interest  income  during  2021  was  primarily  related  to  an  increase  in  gains  on  the 
sale/exchange of assets (up $11.0 million) and increases in income from customer derivative and foreign exchange 
transactions (up $2.9 million and $1.2 million, respectively). These items were partly offset by decreases in sundry 
and  other  miscellaneous  income  (down  $4.6  million),  public  finance  underwriting  fees  (down  $2.9  million)  and 
earnings on the cash surrender value of life insurance (down $1.3 million). Additionally, other non-interest income 
during 2020 included approximately $6.0 million in gains realized on the sale of certain non-hedge related, short-
term  put  options  on  U.S.  Treasury  securities  with  an  aggregate  notional  amount  of  $500  million.  The  put  options 
were not exercised and expired in March 2020.

Gains on the sale/exchange of assets in 2021 included $9.7 million related to an exchange of a branch facility and 
$1.8 million related to the sale of certain parking lots in downtown San Antonio while gains on the sale/exchange of 
assets in 2020 included $758 thousand related to the sale of a branch facility. The increases in income from customer 
derivative and trading activities and income from customer foreign currency transactions were primarily related to 
increases in business volumes. Sundry and other miscellaneous income during 2021 included $3.4 million in card 
related incentives/rebates and $519 thousand in recoveries of prior write-offs, among other things, while sundry and 
other  miscellaneous  income  during  2020  included  $5.3  million  in  card  related  incentives/rebates,  $2.8  million  in 
recoveries of prior write-offs and $512 thousand related to settlements, among other things. The decrease in public 
finance underwriting fees was primarily due to a decrease in business volume. The decrease in earnings on the cash 
surrender value of life insurance was due to lower yields on the investments within the bank-owned life insurance 
portfolio.

Non-Interest Expense

Total non-interest expense for 2021 increased $33.1 million, or 3.9%, compared to 2020. Changes in the various 

components of non-interest expense are discussed below.

Salaries and Wages. Salaries and wages increased $8.2 million, or 2.1%, in 2021 compared to 2020. The increase 
was  primarily  related  to  an  increase  in  incentive  compensation  and,  to  a  lesser  extent,  a  decrease  in  salary  costs 
deferred in connection with loan originations and an increase in commissions. The impact of these items was partly 
offset  by  a  decrease  in  salaries,  due  to  a  decrease  in  the  number  of  employees,  and  a  decrease  in  stock-based 
compensation. Salaries and wages for 2020 also included $5.2 million related to severance costs. 

Employee Benefits. Employee benefits expense for 2021 increased $6.4 million, or 8.4%, compared to 2020. The 
increase was primarily related to an increase in certain discretionary benefit plan expenses and, to a lesser extent, 
increases in medical benefits expense and payroll taxes partly offset by decreases in expenses related to our defined 
benefit retirement and restoration plans, among other things. 

Our  defined  benefit  retirement  and  restoration  plans  were  frozen  in  2001  which  has  helped  to  reduce  the 
volatility in retirement plan expense. We nonetheless still have funding obligations related to these plans and could 
recognize additional expense related to these plans in future years, which would be dependent on the return earned 
on plan assets, the level of interest rates and employee turnover. See Note 12 - Defined Benefit Plans for additional 
information related to our net periodic pension benefit/cost.

Net  Occupancy.  Net  occupancy  expense  for  2021  increased  $4.4  million,  or  4.3%,  compared  to  2020.  The 
increase was primarily related to increases in depreciation on leasehold improvements (up $1.9 million), repairs and 
maintenance/service contracts expense (up $1.8 million) and building depreciation (up $675 thousand), among other 
things, partly offset by a decrease in lease expense (down $581 thousand), among other things. The increases in the 
aforementioned components of net occupancy expense during the comparable periods were impacted, in part, by our 
expansion within the Houston market area.

Technology,  Furniture  and  Equipment.  Technology,  furniture  and  equipment  expense  for  2021  increased  $7.5 
million, or 7.1%, compared to 2020. The increase was primarily related to increases in cloud services expense (up 
$5.9 million) and depreciation of furniture and equipment (up $2.5 million) partly offset by a decrease in software 
maintenance (down $1.1 million).

Deposit Insurance. Deposit insurance expense totaled $12.2 million in 2021 compared to $10.5 million in 2020. 

The increase was primarily related to an increase in total assets partly offset by a decrease in the assessment rate.

Other Non-Interest Expense. Other non-interest expense for 2021 increased $5.1 million, or 3.1%, compared to 
2020.  The  increase  included  increases  in  donations  expense  (up  $8.0  million);  sundry  and  other  miscellaneous 
expenses (up $6.4 million); and fraud losses (up $1.9 million), among other things. Donations expense during 2021 
was impacted by $8.8 million in contributions to the Frost Charitable Foundation. Sundry and other miscellaneous 
expense in 2021 included $4.7 million related to the write-off of certain assets while sundry and other miscellaneous 
expense  in  2020  included  $958  thousand  related  to  the  closure  of  certain  branch  locations  in  our  Houston  market 
area and $454 thousand related to the write-off of certain other assets. The aforementioned items were partly offset 
by  decreases  in  outside  computer  service  expense  (down  $4.3  million);  professional  services  expense  (down 
$2.5  million);  travel,  meals  and  entertainment  expense  (down  $2.2  million);  amortization  of  deferred  costs 
associated with loan commitments (down $1.1 million); and losses on the sale/write-down of foreclosed and other 
assets (down $1.1 million); among other things.

Results of Segment Operations

We are managed under a matrix organizational structure whereby our two primary operating segments, Banking 
and Frost Wealth Advisors, overlap a regional reporting structure. A third operating segment, Non-Banks, is for the 
most part the parent holding company, as well as certain other insignificant non-bank subsidiaries of the parent that, 
for the most part, have little or no activity. A description of each business and the methodologies used to measure 
financial  performance  is  described  in  Note  18  -  Operating  Segments  in  the  accompanying  notes  to  consolidated

Net income for 2021 increased $92.8 million, or 28.8%, compared to 2020. The increase was primarily the result 
of a $241.2 million decrease in credit loss expense, an $8.4 million increase in net interest income partly offset by a 
$100.5 million decrease in non-interest income, a $35.2 million increase in non-interest expense and a $21.1 million 
increase in income tax expense.

Net  interest  income  for  2021  increased  $8.4  million,  or  0.9%,  compared  to  2020.  The  increase  was  primarily 
related to decreases in the average costs of interest-bearing deposit liabilities and other borrowed funds combined 
with  increases  in  the  average  volumes  of  interest-bearing  deposits  (primarily  amounts  held  by  us  in  an  interest-
bearing  account  at  the  Federal  Reserve)  and  taxable  securities  and  an  increase  in  the  average  taxable-equivalent 
yield on loans. The positive impact of these items was partly offset by decreases in the average volumes of loans and 
tax-exempt  securities  and  increases  in  the  average  volumes  of  interest-bearing  deposit  liabilities  and  repurchase 
agreements combined with decreases in the average yields on taxable and tax-exempt securities and interest-bearing 
deposits (primarily amounts held by us in an interest-bearing account at the Federal Reserve). Net interest income 
during 2020 was also positively impacted by the additional day as a result of the leap year. See the analysis of net 
interest income included in the section captioned “Net Interest Income” elsewhere in this discussion.

Credit  loss  expense  for  2021  totaled  $54  thousand  compared  to  $241.2  million  in  2020.  Credit  loss  expense  in 
2020 was impacted by our adoption of a new credit loss accounting standard and the expected credit losses resulting 
from a deterioration in forecasted economic conditions and the current and uncertain future impacts associated with 
the COVID-19 pandemic and recent volatility in oil prices. See the sections captioned “Credit Loss Expense” and 
“Allowance  for  Credit  Losses”  elsewhere  in  this  discussion  for  further  analysis  of  credit  loss  expense  related  to 
loans and off-balance-sheet commitments.

Non-interest income for 2021 decreased $100.5 million, or 31.3%, compared to  2020. Excluding $69 thousand 
and $109.0 million in net gains on securities transactions in 2021 and 2020, respectively, total non-interest income 
for  the  Banking  segment  increased  $8.4  million,  or  4.0%,  during  2021.  This  increase  was  primarily  related  to 
increases in interchange and card transaction fees, service charges on deposit accounts and insurance commissions 
and fees. The increase in interchange and card transaction fees was due to increased transaction volumes as well as 
the  impact  of  new  card  products  partly  offset  by  increases  in  network  costs.  The  increase  in  service  charges  on 
deposit accounts was primarily related to an increase in commercial service charges partly offset by a decrease in 
overdraft charges on consumer accounts. The increase in insurance commissions and fees was the result of increases 
in  contingent  income  and  commission  income,  which  is  further  discussed  below  in  relation  to  Frost  Insurance 
Agency. See the analysis of these categories of non-interest income included in the section captioned “Non-Interest 
Income” included elsewhere in this discussion.

Non-interest expense for 2021 increased $35.2 million, or 4.9%, compared to 2020. The increase was primarily 
due to increases in salaries and wages; other non-interest expense; employee benefit expense; technology, furniture 
and equipment expense; net occupancy expense and deposit insurance expense. The increase in salaries and wages 
was  primarily  related  to  an  increase  in  incentive  compensation  and,  to  a  lesser  extent,  a  decrease  in  salary  costs 
deferred in connection with loan originations and an increase in commissions. The impact of these items was partly 
offset  by  a  decrease  in  salaries,  due  to  a  decrease  in  the  number  of  employees,  and  a  decrease  in  stock-based 
compensation. The increase in other non-interest expense was primarily due to increases in donations; sundry and 
other miscellaneous expenses; and fraud losses, among other things, partly offset by decreases in outside computer 
service  expense;  professional  services  expense;  travel,  meals  and  entertainment  expense;  amortization  of  deferred 
costs associated with loan commitments; and losses on the sale/write-down of foreclosed and other assets; among 
other things. The increase in employee benefits expense was primarily related to an increase in certain discretionary 
benefit plan expenses and, to a lesser extent, increases in medical benefits expense and payroll taxes partly offset by 
decreases  in  expenses  related  to  our  defined  benefit  retirement  and  restoration  plans,  among  other  things.  The 

50

increase in technology, furniture and equipment expense was primarily related to increases in cloud services expense 
and depreciation of furniture and equipment partly offset by a decrease in software maintenance. The increase in net 
occupancy  expense  was  primarily  related  to  increases  in  depreciation  on  leasehold  improvements,  repairs  and 
maintenance/service contracts expense and building depreciation, among other things, partly offset by a decrease in 
lease expense, among other things. The increase in deposit insurance expense was primarily related to an increase in 
total  assets  partly  offset  by  a  decrease  in  the  assessment  rate.  See  the  analysis  of  these  categories  of  non-interest 
expense included in the section captioned “Non-Interest Expense” included elsewhere in this discussion.

Income tax expense for 2021 increased $21.1 million, or 103.9%, compared to 2020. See the section captioned 

“Income Taxes” elsewhere in this discussion.

Frost Insurance Agency, which is included in the Banking operating segment, had gross commission revenues of 
$52.5 million during 2021 compared to $51.1 million during 2020. The increase in gross commission revenues was 
the result of increases in contingent income and commission income. The increase in contingent income was related 
to growth within the portfolio combined with improvement in the loss performance of insurance policies previously 
placed.  The  increase  in  commission  income  was  primarily  related  to  increases  in  commercial  lines  property  and 
casualty  commissions,  related  to  increased  market  rates,  and  an  increase  in  life  insurance  commissions,  related  to 
fluctuations in business volumes, partly offset by a decrease in benefit plan commissions, related to fluctuations in 
business  volumes.  See  the  analysis  of  insurance  commissions  and  fees  included  in  the  section  captioned  “Non-
Interest Income” included elsewhere in this discussion.

Frost Wealth Advisors

Net income for 2021 increased $17.5 million, or 90.9%, compared to 2020. The increase was primarily due to a 
$22.2 million increase in non-interest income and a $658 thousand decrease in non-interest expense partly offset by 
a $4.7 million increase in income tax expense and a $647 thousand decrease in net interest income. 

Net interest income for 2021 decreased $647 thousand, or 23.3%, compared to 2020. This decrease was primarily 
due to a decrease in the average funds transfer price allocated to the funds provided by Frost Wealth Advisors. The 
decrease in the average funds transfer price was primarily due to a decrease in market interest rates. See the analysis 
of net interest income included in the section captioned “Net Interest Income” included elsewhere in this discussion.

Non-interest income for 2021 increased $22.2 million, or 15.3%, compared to 2020. The increase was primarily 
related to an increase in trust and investment management fees and, to a lesser extent, an increase in other charges, 
commissions and fees. Trust and investment management fee income is the most significant income component for 
Frost  Wealth  Advisors.  Investment  management  fees  are  the  most  significant  component  of  trust  and  investment 
management  fees,  making  up  approximately  82.3%  and  83.6%  of  total  trust  and  investment  management  fees  for 
2021 and 2020, respectively. The increase in trust and investment management fees was primarily due to increases 
in  investment  management  fees,  oil  and  gas  fees,  estate  fees  and  custody  fees.  The  increases  in  investment 
management fees and custody fees were primarily related to higher average equity valuations as well as increases in 
the  number  of  accounts.  Oil  and  gas  fees  during  2021  were  impacted  by  an  increases  in  oil  and  gas  prices.  The 
increase in estate fees was primarily related to an increase in the aggregate value of estates settled. The increase in 
other charges, commissions and fees was primarily related to increases in income from the sale of mutual funds and 
income  from  the  sale  of  annuities  partly  offset  by  a  decrease  in  income  from  the  placement  of  money  market 
accounts, which was impacted by lower average market rates. See the analysis of trust and investment management 
fees  and  other  charges,  commissions  and  fees  included  in  the  section  captioned  “Non-Interest  Income”  included 
elsewhere in this discussion.

Non-interest expense for 2021 decreased $658 thousand, or 0.5%, compared to 2020. The decrease was primarily 
due to decreases in other non-interest expense and net occupancy expense partly offset by an increase in technology, 
furniture and equipment expense. The decrease in other non-interest expense was primarily related to decreases in 
outside  computer  service  expense;  travel,  meals  and  entertainment  expense;  and  professional  service  expense; 
among other things; partly offset by increases in subscriptions expense and platform fees expense. The decrease in 
net occupancy expense was primarily related to a decrease in lease expense. The increase in technology, furniture 
and equipment expense was primarily related to an increase in cloud services expense.

Non-Banks

The Non-Banks operating segment had a net loss of $9.0 million for 2021 compared to a net loss of $10.6 million 
in  2020.  The  decreased  net  loss  was  primarily  due  to  decreases  in  other  non-interest  expense  and  net  interest 
expense. The decrease in other non-interest expense was primarily due to decreases in professional services expense 
and travel, meals and entertainment expense. The decrease in net interest expense was primarily related to a decrease 
in  the  average  rates  paid  on  our  long-term  borrowings.  Net  interest  expense  was  also  positively  impacted  by  the 
redemption, during the fourth quarter of 2021, of $13.4 million of junior subordinated deferrable interest debentures 
issued to WNB Capital Trust I. 

Income Taxes

We recognized income tax expense of $46.5 million, for an effective tax rate of 9.5%, in 2021 compared to $20.2 
million, for an effective tax rate of 5.7%, in 2020. The effective income tax rates differed from the U.S. statutory 
federal income tax rate of 21% during 2021 and 2020 primarily due to the effect of tax-exempt income from loans, 
securities and life insurance policies and the income tax effects associated with stock-based compensation, among 
other things, and their relative proportion to total pre-tax net income. The increase in the effective tax rate during 
2021 was primarily related to an increase in pre-tax net income, partly off-set by the impact of higher discrete tax 
benefits associated with stock-based compensation. The effective tax rate during 2020 was also impacted by a one-
time, discrete tax benefit associated with an asset contribution to a charitable trust. See Note 13 - Income Taxes in 
the accompanying notes to consolidated financial statements elsewhere in this report.

Deposits  continue  to  be  our  primary  source  of  funding.  Average  deposits  increased  $7.0  billion,  or  22.4%,  in 
2021 compared to 2020. Non-interest-bearing deposits remain a significant source of funding, which has been a key 
factor in maintaining our relatively low cost of funds. Average non-interest-bearing deposits totaled 43.3% of total 
average  deposits  in  2021  compared  to  43.1%  in  2020.  Though  federal  prohibitions  on  the  payment  of  interest  on 
demand deposits were repealed in 2011, we have not experienced any significant additional costs as a result. Should 
the market dictate, we may increase the interest rates we pay on some or all of our various interest-bearing deposit 
products. This could lead to a decrease in the relative proportion of non-interest-bearing deposits to total deposits.

52

We primarily invest funds in loans, securities and interest-bearing deposits (primarily amounts held by us in an 
interest-bearing account at the Federal Reserve). Average loans decreased $394.8 million, or 2.3%, ($88.1 million, 
or 0.6% excluding PPP loans) in 2021 compared to 2020 while average securities increased $193.6 million, or 1.5%, 
in 2021 compared to 2020. Average interest-bearing deposits (primarily amounts held by us in an interest-bearing 
account at the Federal Reserve) increased $8.2 billion, or 155.2%, in 2021 compared to 2020, primarily as a result of 
deposit growth.

Loans

Overview. Details of our loan portfolio are presented in Note 3 - Loans in the accompanying notes to consolidated 
financial statements included elsewhere in this report. Year-end total loans decreased $1.1 billion, or 6.5%, during 
2021 compared to 2020. As further discussed below, during the second quarter of 2020, we began originating loans 
to  qualified  small  businesses  under  the  PPP  administered  by  the  SBA  under  the  provisions  of  the  CARES  Act. 
Excluding PPP loans, total loans would have otherwise increased $860.1 million, or 5.7%, from December 31, 2020. 
The  majority  of  our  loan  portfolio  is  comprised  of  commercial  and  industrial  loans,  energy  loans  and  real  estate 
loans. Commercial and industrial loans made up 32.9% and 28.4% (33.7% and 32.9% excluding PPP loans) of total 
loans at December 31, 2021 and 2020 while energy loans made up 6.6% and 7.1% (6.8% and 8.2% excluding PPP 
loans) of total loans at both December 31, 2021 and 2020 and real estate loans made up 55.0% and 47.7% (56.5% 
and 55.5% excluding PPP loans) of total loans at December 31, 2021 and 2020. Energy loans include commercial 
and industrial loans, leases and real estate loans to borrowers in the energy industry. Real estate loans include both 
commercial and consumer balances. It is possible that the on-going effects of COVID-19 could continue to impact 
demand for our loan products. 

Loan Origination/Risk Management. We have certain lending policies and procedures in place that are designed 
to maximize loan income within an acceptable level of risk. Management reviews and approves these policies and 
procedures on a regular basis. A reporting system supplements the review process by providing management with 
frequent  reports  related  to  loan  production,  loan  quality,  concentrations  of  credit,  loan  delinquencies  and  non-
performing and potential problem loans. Diversification in the loan portfolio is a means of managing risk associated 
with fluctuations in economic conditions. We have begun to explore the credit and reputational risks associated with 
climate change and their potential impact on the foregoing and are also closely monitoring regulatory developments 
on climate risk. This includes, among other things, researching and developing a formalized approach to considering 
climate  change  related  risks  in  our  underwriting  processes.  This  approach  will  be  impacted,  in  part,  by  the 
accessibility and reliability of both customer climate risk data and climate risk data in general. One of the objectives 
of these efforts is to enable us to better understand the climate change related risks associated with our customers' 
business activities and to be able to monitor their response to those risks and their ultimate impact on our customers. 

Commercial  and  industrial  loans  are  underwritten  after  evaluating  and  understanding  the  borrower’s  ability  to 
operate profitably and prudently expand its business. Underwriting standards are designed to promote relationship 
banking rather than transactional banking. Once it is determined that the borrower’s management possesses sound 
ethics  and  solid  business  acumen,  our  management  examines  current  and  projected  cash  flows  to  determine  the 
ability  of  the  borrower  to  repay  their  obligations  as  agreed.  Commercial  and  industrial  loans  are  primarily  made 
based  on  the  identified  cash  flows  of  the  borrower  and  secondarily  on  the  underlying  collateral  provided  by  the 
borrower. The cash flows of borrowers, however, may not be as expected and the collateral securing these loans may 
fluctuate in value. Most commercial and industrial loans are secured by the assets being financed or other business 
assets such as accounts receivable or inventory and may incorporate a personal guarantee; however, some short-term 
loans may be made on an unsecured basis. In the case of loans secured by accounts receivable, the availability of 
funds  for  the  repayment  of  these  loans  may  be  substantially  dependent  on  the  ability  of  the  borrower  to  collect 
amounts due from its customers.

Our energy loan portfolio includes loans for production, energy services and other energy loans, which includes 
private clients, transportation and equipment providers, manufacturers, refiners and traders. The origination process 
for energy loans is similar to that of commercial and industrial loans. Because, however, of the average loan size, the 
significance of the portfolio and the specialized nature of the energy industry, our energy lending requires a highly 
prescriptive underwriting policy. Production loans are secured by proven, developed and producing reserves. Loan 
proceeds  for  these  types  of  loans  are  typically  used  for  the  development  and  drilling  of  additional  wells,  the 
acquisition of additional production, and/or the acquisition of additional properties to be developed and drilled. Our 
customers  in  this  sector  are  generally  large,  independent,  private  owner-producers  or  large  corporate  producers. 
These  borrowers  typically  have  large  capital  requirements  for  drilling  and  acquisitions,  and  as  such,  loans  in  this 
portfolio are generally greater than $10 million. Production loans are collateralized by the oil and gas interests of the 

53

borrower.  Collateral  values  are  determined  by  the  risk-adjusted  and  limited  discounted  future  net  revenue  of  the 
reserves.  Our  valuations  take  into  consideration  geographic  and  reservoir  differentials  as  well  as  cost  structures 
associated  with  each  borrower.  Collateral  value  is  calculated  at  least  semi-annually  using  third-party  engineer-
prepared reserve studies. These reserve studies are conducted using a discount factor and base case assumptions for 
the current and future value of oil and gas. To qualify as collateral, typically reserves must be proven, developed and 
producing.  For  certain  borrowers,  collateral  may  include  up  to  20%  proven,  non-producing  reserves.  Loan 
commitments  are  limited  to  65%  of  estimated  reserve  value.  Cash  flows  must  be  sufficient  to  amortize  the  loan 
commitment  within  120%  of  the  half-life  of  the  underlying  reserves.  Loan  commitments  generally  must  also  be 
100% covered by the risk-adjusted and limited discounted future net revenue of the reserves when stressed at 75% of 
our  base  case  price  assumptions.  In  addition,  the  ratio  of  the  borrower's  debt  to  earnings  before  interest,  taxes, 
depreciation  and  amortization  (“EBITDA”)  should  generally  not  exceed  350%.  We  generally  require  production 
borrowers to maintain an active hedging program to manage risk and to have at least 50% of their production hedged 
for two years.

Oil  and  gas  service,  transportation,  and  equipment  providers  are  economically  aligned  due  to  their  reliance  on 
drilling and active oil and gas development. Income for these borrowers is highly dependent on the level of drilling 
activity and rig utilization, both of which are driven by the current and future outlook for the price of oil and gas. We 
mitigate  the  credit  risk  in  this  sector  through  conservative  concentration  limits  and  guidelines  on  the  profile  of 
eligible borrowers. Guidelines require that the companies have extensive experience through several industry cycles, 
and that they be supported by financially competent and committed guarantors who provide a significant secondary 
source of repayment. Borrowers in this sector are typically privately-owned, middle-market companies with annual 
sales of less than $100 million. The services provided by companies in this sector are highly diversified, and include 
down-hole  testing  and  maintenance,  providing  and  threading  drilling  pipe,  hydraulic  fracturing  services  or 
equipment, seismic testing and equipment and other direct or indirect providers to the oil and gas production sector.

Our  private  client  portfolio  primarily  consists  of  loans  to  wealthy  individuals  and  their  related  oil  and  gas 
exploration and production entities, where the oil and gas producing reserves are not considered to be the primary 
source  of  repayment.  These  borrowers  and  guarantors  typically  have  significant  sources  of  wealth  including 
significant  liquid  assets  and/or  cash  flow  from  other  investments  which  can  fully  repay  the  loans.  The  credit 
structures of these loans are generally similar to those of energy production loans, described above, with respect to 
the valuation of the reserves taken as collateral and the repayment structures.

Although  no  balances  were  outstanding  at  December  31,  2021  and  2020,  in  prior  years  we  have  had  a  small 
portfolio of loans to refiners where our credit involvement with these customers was through purchases of shared 
national  credit  syndications.  These  borrowers  refine  crude  oil  into  gasoline,  diesel,  jet  fuel,  asphalt  and  other 
petrochemicals  and  are  not  dependent  on  drilling  or  development.  All  of  the  borrowers  in  this  portfolio  are  very 
large public companies that are important employers in several of our major markets. These borrowers, for the most 
part,  have  been  long-term  customers  and  we  have  a  strong  relationship  with  these  companies  and  their  executive 
management.  There  is  no  new  customer  origination  process  for  this  segment  and  any  outstanding  balances  are 
expected to only reflect the needs of these existing relationships.

We also have a small portfolio of loans to energy trading companies that serve as intermediaries that buy and sell 
oil,  gas,  other  petrochemicals,  and  ethanol.  These  companies  are  not  dependent  on  drilling  or  development.  As  a 
general  policy,  we  do  not  lend  to  energy  traders;  however,  we  have  made  an  exception  to  this  policy  for  certain 
customers based upon their underlying business models which minimize risk as commodities are bought only to fill 
existing orders (back-to-back trading). As such, the commodity price risk and sale risk are eliminated.

PPP  loans,  which  we  began  originating  in  April  2020,  are  loans  to  qualified  small  businesses  under  the  PPP 
administered by the SBA under the provisions of the CARES Act. Loans covered by the PPP may be eligible for 
loan  forgiveness  for  certain  costs  incurred  related  to  payroll,  group  health  care  benefit  costs  and  qualifying 
mortgage,  rent  and  utility  payments.  The  remaining  loan  balance  after  forgiveness  of  any  amounts  is  still  fully 
guaranteed by the SBA. Terms of the PPP loans include the following (i) maximum amount limited to the lesser of 
$10  million  or  an  amount  calculated  using  a  payroll-based  formula,  (ii)  maximum  loan  term  of  five  years, 
(iii) interest rate of 1.00%, (iv) no collateral or personal guarantees are required, (v) no payments are required until 
the date on which the forgiveness amount relating to the loan is remitted to the lender and (vi) loan forgiveness up to 
the full principal amount of the loan and any accrued interest, subject to certain requirements including that no more 
than  40%  of  the  loan  forgiveness  amount  may  be  attributable  to  non-payroll  costs.  In  return  for  processing  and 
booking a PPP loan, the SBA paid lenders a processing fee tiered by the size of the loan (5% for loans of not more 

54

than $350 thousand; 3% for loans of more than $350 thousand and less than $2 million; and 1% for loans of at least 
$2 million).

Commercial  real  estate  loans  are  subject  to  underwriting  standards  and  processes  similar  to  commercial  and 
industrial loans, in addition to those of real estate loans. These loans are viewed primarily as cash flow loans and 
secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal 
amounts and the repayment of these loans is generally largely dependent on the successful operation of the property 
securing the loan or the business conducted on the property securing the loan. Commercial real estate loans may be 
more adversely affected by conditions in the real estate markets or in the general economy. The properties securing 
our commercial real estate portfolio are diverse in terms of type and geographic location. This diversity helps reduce 
our  exposure  to  adverse  economic  events  that  affect  any  single  market  or  industry.  Management  monitors  and 
evaluates commercial real estate loans based on collateral, geography and risk grade criteria. As a general rule, we 
avoid financing single-purpose projects unless other underwriting factors are present to help mitigate risk. We also 
utilize  third-party  experts  to  provide  insight  and  guidance  about  economic  conditions  and  trends  affecting  market 
areas  we  serve.  In  addition,  management  tracks  the  level  of  owner-occupied  commercial  real  estate  loans  versus 
non-owner occupied loans. At December 31, 2021, approximately 48.4% of the outstanding principal balance of our 
commercial real estate loans were secured by owner-occupied properties.

With respect to loans to developers and builders that are secured by non-owner occupied properties that we may 
originate from time to time, we generally require the borrower to have had an existing relationship with us and have 
a proven record of success. Construction loans are underwritten utilizing feasibility studies, independent appraisal 
reviews,  sensitivity  analysis  of  absorption  and  lease  rates  and  financial  analysis  of  the  developers  and  property 
owners.  Construction  loans  are  generally  based  upon  estimates  of  costs  and  value  associated  with  the  completed 
project. These estimates may be inaccurate. Construction loans often involve the disbursement of substantial funds 
with repayment substantially dependent on the success of the ultimate project. Sources of repayment for these types 
of loans may be pre-committed permanent loans from approved long-term lenders, sales of developed property or an 
interim loan commitment from us until permanent financing is obtained. These loans are closely monitored by on-
site inspections and are considered to have higher risks than other real estate loans due to their ultimate repayment 
being sensitive to interest rate changes, governmental regulation of real property, general economic conditions and 
the availability of long-term financing.

We  originate  consumer  loans  utilizing  a  credit  scoring  analysis  to  supplement  the  underwriting  process.  To 
monitor and manage consumer loan risk, policies and procedures are developed and modified, as needed, jointly by 
line  and  staff  personnel.  This  activity,  coupled  with  relatively  small  loan  amounts  that  are  spread  across  many 
individual  borrowers,  minimizes  risk.  Additionally,  trend  and  outlook  reports  are  reviewed  by  management  on  a 
regular basis. Underwriting standards for home equity loans are heavily influenced by statutory requirements, which 
include, but are not limited to, loan-to-value limitations, collection remedies, the number of such loans a borrower 
can have at one time and documentation requirements.

We  maintain  an  independent  loan  review  department  that  reviews  and  validates  the  credit  risk  program  on  a 
periodic basis. Results of these reviews are presented to management and the appropriate committees of our board of 
directors.  The  loan  review  process  complements  and  reinforces  the  risk  identification  and  assessment  decisions 
made by lenders and credit personnel, as well as our policies and procedures.

Commercial  and  Industrial.  Commercial  and  industrial  loans  increased  $409.6  million,  or  8.3%,  during  2021 
compared  to  2020.  Our  commercial  and  industrial  loans  are  a  diverse  group  of  loans  to  small,  medium  and  large 
businesses. The purpose of these loans varies from supporting seasonal working capital needs to term financing of 
equipment. While some short-term loans may be made on an unsecured basis, most are secured by the assets being 
financed with collateral margins that are consistent with our loan policy guidelines. The commercial and industrial 
loan portfolio also includes the commercial lease and purchased shared national credits.

Energy. Energy loans include loans to entities and individuals that are engaged in various energy-related activities 
including  (i)  the  development  and  production  of  oil  or  natural  gas,  (ii)  providing  oil  and  gas  field  servicing, 
(iii)  providing  energy-related  transportation  services  (iv)  providing  equipment  to  support  oil  and  gas  drilling 
(v) refining petrochemicals, or (vi) trading oil, gas and related commodities. Energy loans decreased $157.4 million, 
or 12.7%, during 2021 compared to 2020. The average loan size, the significance of the portfolio and the specialized 
nature of the energy industry requires a highly prescriptive underwriting policy. Exceptions to this policy are rarely 
granted.  Due  to  the  large  borrowing  requirements  of  this  customer  base,  the  energy  loan  portfolio  includes 
participations and purchased shared national credits.

55

Paycheck Protection Program. PPP loans include loans to businesses and other entities that would otherwise be 
reported  as  commercial  and  industrial  loans  and,  to  a  lesser  extent,  energy  loans,  originated  under  the  guidelines 
discussed above. We funded approximately $1.4 billion and $3.3 billion of SBA-approved PPP loans during 2021 
and 2020, respectively. During 2021 and 2020, we recognized approximately $97.3 million and $59.5 million in PPP 
loan related deferred processing fees (net of amortization of related deferred origination costs), respectively, as yield 
adjustments and these amounts are included in interest income on loans. As a result of the inclusion of these net fees 
in interest income, the average yields on PPP loans were 6.26% during 2021 and 3.78% during 2020, compared to 
the  stated  interest  rate  of  1.0%  on  these  loans.  We  expect  to  recognize  additional  PPP  loan  related  deferred 
processing fees (net of deferred origination costs) totaling approximately $2.8 million as a yield adjustment during 
2022.

Industry Concentrations. As of December 31, 2021 and 2020, there were no concentrations of loans related to any 
single  industry,  as  segregated  by  Standard  Industrial  Classification  code  (“SIC  code”),  in  excess  of  10%  of  total 
loans. The largest industry concentrations at such dates were related to the energy industry, which totaled 6.6% of 
total loans, or 6.8% excluding PPP loans, as of December 31, 2021 and 7.1% of total loans, or 8.2% excluding PPP 
loans, as of December 31, 2020. The SIC code system is a federally designed standard industrial numbering system 
used  by  us  to  categorize  loans  by  the  borrower’s  type  of  business.  The  following  table  summarizes  the  industry 
concentrations of our loan portfolio, as segregated by SIC code, stated as a percentage of year-end total loans as of 
December 31, 2021 and 2020.

Large Credit Relationships. The market areas served by us include three of the top ten most populated cities in 
the United States. These market areas are also home to a significant number of Fortune 500 companies. As a result, 
we originate and maintain large credit relationships with numerous commercial customers in the ordinary course of 
business. We consider large credit relationships to be those with commitments equal to or in excess of $10.0 million, 
excluding treasury management lines exposure, prior to any portion being sold. Large relationships also include loan 
participations purchased if the credit relationship with the agent is equal to or in excess of $10.0 million. In addition 
to  our  normal  policies  and  procedures  related  to  the  origination  of  large  credits,  one  of  our  Regional  Credit 
Committees must approve all new credit facilities which are part of large credit relationships and renewals of such 
credit  facilities  with  exposures  between  $20.0  million  and  $30.0  million.  Our  Central  Credit  Committee  must 
approve all new credit facilities which are part of large credit relationships and renewals of such credit facilities with 
exposures that exceed $30.0 million. The Regional and Central Credit Committees meet regularly to review large 
credit relationship activity and discuss the current pipeline, among other things.

Purchased  Shared  National  Credits  (“SNCs”).  Purchased  SNCs  are  participations  purchased  from  upstream 
financial  organizations  and  tend  to  be  larger  in  size  than  our  originated  portfolio.  Our  purchased  SNC  portfolio 
totaled  $698.4  million  at  December  31,  2021  decreasing  $89.7  million,  or  11.4%,  from  $788.1  million  at 
December 31, 2020. At December 31, 2021, 27.2% of outstanding purchased SNCs were related to the construction 
industry, 23.2% of outstanding purchased SNCs were related to the energy industry, 14.0% were related to the real 
estate  management  industry  and  13.4%  of  outstanding  purchased  SNCs  were  related  to  the  financial  services 
industry. The remaining purchased SNCs were diversified throughout various other industries, with no other single 
industry exceeding 10% of the total purchased SNC portfolio. Additionally, almost all of the outstanding balance of 
purchased SNCs was included in the energy and commercial and industrial portfolios, with the remainder included 
in the real estate categories. SNC participations are originated in the normal course of business to meet the needs of 
our  customers.  As  a  matter  of  policy,  we  generally  only  participate  in  SNCs  for  companies  headquartered  in  or 
which have significant operations within our market areas. In addition, we must have direct access to the company’s 
management, an existing banking relationship or the expectation of broadening the relationship with other banking 
products and services within the following 12 to 24 months. SNCs are reviewed at least quarterly for credit quality 
and business development successes.

Real  Estate  Loans.  Real  estate  loans  increased  $636.2  million,  or  7.6%,  during  2021  compared  to  2020.  Real 
estate loans include both commercial and consumer balances. Commercial real estate loans totaled $7.6 billion, or 
84.3%  of  total  real  estate  loans,  at  December  31,  2021  and  $7.0  billion,  or  84.1%  of  total  real  estate  loans,  at 
December 31, 2020. The majority of this portfolio consists of commercial real estate mortgages, which includes both 
permanent and intermediate term loans. Loans secured by owner-occupied properties make up a significant portion 
of our commercial real estate portfolio. These loans are viewed primarily as cash flow loans and secondarily as loans 
secured  by  real  estate.  Consequently,  these  loans  must  undergo  the  analysis  and  underwriting  process  of  a 
commercial and industrial loan, as well as that of a real estate loan.

Consumer  Loans.  The  consumer  loan  portfolio  at  December  31,  2021  increased  $51.7  million,  or  2.8%,  from 
December  31,  2020.  As  the  following  table  illustrates,  the  consumer  loan  portfolio  has  two  distinct  segments, 
including consumer real estate and consumer and other.

Consumer  real  estate  loans  at  December  31,  2021  increased  $80.0  million,  or  6.0%,  from  December  31,  2020. 
Combined, home equity loans and lines of credit made up 59.8% and 58.8% of the consumer real estate loan total at 
December  31,  2021  and  2020,  respectively.  We  offer  home  equity  loans  up  to  80%  of  the  estimated  value  of  the 
personal residence of the borrower, less the value of existing mortgages and home improvement loans. We have not 
generally originated 1-4 family mortgage loans since 2000; however, from time to time, we invested in such loans to 
meet  the  needs  of  our  customers  or  for  other  regulatory  compliance  purposes.  Nonetheless,  we  expect  to  begin 
regular production of 1-4 family mortgage loans for portfolio investment purposes in the second half of 2022. The

consumer  and  other  loan  portfolio  at  December  31,  2021  decreased  $28.3  million,  or  5.6%,  from  December  31, 
2020.  This  portfolio  primarily  consists  of  automobile  loans,  unsecured  revolving  credit  products,  personal  loans 
secured by cash and cash equivalents, and other similar types of credit facilities. 

Foreign  Loans.  We  make  U.S.  dollar-denominated  loans  and  commitments  to  borrowers  in  Mexico.  The 
outstanding  balance  of  these  loans  and  the  unfunded  amounts  available  under  these  commitments  were  not 
significant at December 31, 2021 or 2020.

We generally structure commercial loans with shorter-term maturities in order to match our funding sources and 
to  enable  us  to  effectively  manage  the  loan  portfolio  by  providing  the  flexibility  to  respond  to  liquidity  needs, 
changes in interest rates and changes in underwriting standards and loan structures, among other things. Due to the 
shorter-term nature of such loans, from time to time in the ordinary course of business and without any contractual 
obligation  on  our  part,  we  will  renew/extend  maturing  lines  of  credit  or  refinance  existing  loans  at  their  maturity 
dates. Some loans may renew multiple times in a given year as a result of general customer practice and need. These 
renewals,  extensions  and  refinancings  are  made  in  the  ordinary  course  of  business  for  customers  that  meet  our 
normal  level  of  credit  standards.  Such  borrowers  typically  request  renewals  to  support  their  on-going  working 
capital  needs  to  finance  their  operations.  Such  borrowers  are  not  experiencing  financial  difficulties  and  generally 
could  obtain  similar  financing  from  another  financial  institution.  In  connection  with  each  renewal,  extension  or 
refinancing, we may require a principal reduction, adjust the rate of interest and/or modify the structure and other

terms  to  reflect  the  current  market  pricing/structuring  for  such  loans  or  to  maintain  competitiveness  with  other 
financial institutions. In such cases, we do not generally grant concessions, and, except for those reported in Note 3 - 
Loans, any such renewals, extensions or refinancings that occurred during the reported periods were not deemed to 
be troubled debt restructurings pursuant to applicable accounting guidance. Loans exceeding $1.0 million undergo a 
complete underwriting process at each renewal.

Accruing  past  due  loans  at  December  31,  2021  increased  $17.9  million  compared  to  December  31,  2020.  The 
increase was primarily due to increases in past due non-construction related commercial real estate loans (up $25.5 
million) and past due PPP loans (up $23.7 million). PPP loans are fully guaranteed by the SBA and we expect to 
collect all amounts due related to these loans. Excluding PPP loans, accruing past due loans decreased $5.8 million 
as the aforementioned increase in past due non-construction related commercial real estate loans was entirely offset 
by  decreases  in  past  due  commercial  and  industrial  loans  (down  $13.4  million)  and  past  due  energy  loans  (down 
$12.2 million) and, to a lesser extent, decreases in past due consumer real estate loans (down $3.5 million), past due 
consumer and other loans (down $1.5 million) and past due construction loans (down $668 thousand).

Non-accrual  loans  at  December  31,  2021  decreased  $7.7  million  from  December  31,  2020  primarily  due  to  a 
decrease  in  non-accrual  energy  loans.  The  decrease  was  primarily  related  to  principal  payments  and,  to  a  lesser 
extent,  loans  returning  to  accrual  status  and  charge-offs,  partly  offset  by  new  loans  placed  on  non-accrual  status 
during 2021.

Generally, loans are placed on non-accrual status if principal or interest payments become 90 days past due and/
or management deems the collectibility of the principal and/or interest to be in question, as well as when required by 
regulatory  requirements.  Once  interest  accruals  are  discontinued,  accrued  but  uncollected  interest  is  charged  to 
current  year  operations.  Subsequent  receipts  on  non-accrual  loans  are  recorded  as  a  reduction  of  principal,  and 
interest  income  is  recorded  only  after  principal  recovery  is  reasonably  assured.  Classification  of  a  loan  as  non-
accrual does not preclude the ultimate collection of loan principal or interest. There were no non-accrual commercial 
and industrial loans in excess of $5.0 million at December 31, 2021. Non-accrual commercial and industrial loans 
included one credit relationship in excess of $5.0 million with an aggregate balance of $9.0 million at December 31, 
2020.  We  recognized  a  charge-off  totaling  $861  thousand  related  to  this  relationship  during  2021  while  the 
remainder  of  the  decrease  was  related  to  principal  payments  made  by  the  borrower.  Non-accrual  energy  loans 
included  one  credit  relationship  in  excess  of  $5  million  totaling  $9.6  million  at  December  31,  2021.  This  credit 
relationship  was  previously  reported  as  non-accrual  with  an  aggregate  balance  of  $20.1  million  at  December  31, 
2020. The decrease in the aggregate balance of this credit relationship was related to principal payments made by the 
borrower.  Non-accrual  real  estate  loans  primarily  consist  of  land  development,  1-4  family  residential  construction 
credit  relationships  and  loans  secured  by  office  buildings  and  religious  facilities.  There  were  no  non-accrual 
commercial real estate loans in excess of $5.0 million at December 31, 2021 or December 31, 2020.

The COVID-19 pandemic has contributed to an increased risk of delinquencies, defaults and foreclosures. As a 
result of the COVID-19 pandemic, a significant number and amount of our loans experienced ratings downgrades, 
credit  deterioration  and  defaults.  We  have  a  significant  amount  of  loans  in  certain  industries  that  have  been 
particularly impacted. These include energy, hotels/lodging, restaurants, entertainment and commercial real estate, 
among others. See additional information about the effects of and risks associated with the COVID-19 pandemic in 
the  section  captioned  “Recent  Developments  Related  to  COVID-19”  elsewhere  in  this  discussion  and  Part  I.  Item 
1A. Risk Factors elsewhere in this report.

Allowance For Credit Losses

As discussed in Note 1 - Summary of Significant Accounting Policies in the accompanying notes to consolidated 
financial statements, our policies and procedures related to accounting for credit losses changed on January 1, 2020 
in  connection  with  the  adoption  of  a  new  accounting  standard  update  as  codified  in  Accounting  Standards 
Codification  (“ASC”)  Topic  326  (“ASC  326”)  Financial  Instruments  -  Credit  Losses.  In  the  case  of  off-balance-
sheet credit exposures, the allowance for credit losses is a liability account, calculated in accordance with ASC 326, 
reported  as  a  component  of  accrued  interest  payable  and  other  liabilities  in  our  consolidated  balance  sheets.  The 
amount  of  each  allowance  account  represents  management's  best  estimate  of  current  expected  credit  losses 
(“CECL”)  on  these  financial  instruments  considering  available  information,  from  internal  and  external  sources, 
relevant  to  assessing  exposure  to  credit  loss  over  the  contractual  term  of  the  instrument.  Relevant  available 
information includes historical credit loss experience, current conditions and reasonable and supportable forecasts. 
While historical credit loss experience provides the basis for the estimation of expected credit losses, adjustments to 
historical  loss  information  may  be  made  for  differences  in  current  portfolio-specific  risk  characteristics, 
environmental  conditions  or  other  relevant  factors.  While  management  utilizes  its  best  judgment  and  information 
available,  the  ultimate  adequacy  of  our  allowance  accounts  is  dependent  upon  a  variety  of  factors  beyond  our 
control,  including  the  performance  of  our  portfolios,  the  economy,  changes  in  interest  rates  and  the  view  of  the 
regulatory  authorities  toward  classification  of  assets.  For  additional  information  regarding  our  accounting  policies 
related  to  credit  losses,  refer  to  Note  1  -  Summary  of  Significant  Accounting  Policies  and  Note  3  -  Loans  in  the 
accompanying notes to consolidated financial statements.

Allowance for Credit Losses - Loans. The table below provides an allocation of the year-end allowance for credit 
losses on loans by loan portfolio segment; however, allocation of a portion of the allowance to one segment does not 
preclude its availability to absorb losses in other segments.

The allowance allocated to commercial and industrial loans totaled $72.1 million, or 1.34% of total commercial 
and industrial loans, at December 31, 2021 decreasing $1.8 million, or 2.4%, compared to $73.8 million, or 1.49% 
of  total  commercial  and  industrial  loans  at  December  31,  2020.  Modeled  expected  credit  losses  decreased  $18.7 
million while qualitative factor (“Q-Factor”) and other qualitative adjustments related to commercial and industrial 
loans  increased  $11.7  million.  Specific  allocations  for  commercial  and  industrial  loans  that  were  evaluated  for 
expected credit losses on an individual basis increased $5.2 million, or 98.0%, from $5.3 million at December 31, 
2020 to $10.5 million at December 31, 2021. The increase in specific allocations for commercial and industrial loans 

62

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
was primarily related to several newly downgraded credit relationships with specific allocations totaling $9.2 million 
partly  offset  by  reductions  in  allocations  for  certain  other  loans  due  to  principal  payments  received  and  the 
recognition of charge-offs. 

The allowance allocated to energy loans totaled $17.2 million, or 1.60% of total energy loans, at December 31, 
2021  decreasing  $22.3  million,  or  56.5%,  compared  to  $39.6  million,  or  3.20%  of  total  energy  loans  at 
December 31, 2020. Modeled expected credit losses related to energy loans decreased $2.5 million while Q-Factor 
and  other  qualitative  adjustments  related  to  energy  loans  decreased  $15.8  million.  Specific  allocations  for  energy 
loans that were evaluated for expected credit losses on an individual basis totaled $5.5 million at December 31, 2021 
decreasing  $3.9  million,  or  41.9%,  compared  to  $9.4  million  at  December  31,  2020.  The  decrease  in  specific 
allocations  for  energy  loans  was  primarily  related  to  principal  payments  received  and,  to  a  lesser  extent,  the 
recognition of charge-offs. 

The allowance allocated to commercial real estate loans totaled $144.9 million, or 1.91% of total commercial real 
estate loans, at December 31, 2021 increasing $10.0 million, or 7.4%, compared to $134.9 million, or 1.92% of total 
commercial real estate loans at December 31, 2020. Modeled expected credit losses related to commercial real estate 
loans decreased $108.5 million while Q-Factor and other qualitative adjustments related to commercial real estate 
loans  increased  $118.6  million.  Specific  allocations  for  commercial  real  estate  loans  that  were  evaluated  for 
expected credit losses on an individual basis decreased from $513 thousand at December 31, 2020 to $400 thousand 
at December 31, 2021. 

The allowance allocated to consumer real estate loans totaled $6.6 million, or 0.47% of total consumer real estate 
loans,  at  December  31,  2021  decreasing  $1.3  million,  or  16.9%,  compared  to  $7.9  million,  or  0.60%  of  total 
consumer real estate loans at December 31, 2020 primarily due to modeled expected credit losses which decreased 
$1.4 million. 

The  allowance  allocated  to  consumer  loans  totaled  $7.8  million,  or  1.64%  of  total  consumer  loans,  at 
December  31,  2021  increasing  $874  thousand,  or  12.6%,  compared  to  $7.0  million,  or  1.38%  of  total  consumer 
loans  at  December  31,  2020.  Modeled  expected  credit  losses  related  to  consumer  loans  decreased  $548  thousand 
while Q-Factor and other qualitative adjustments related to consumer loans increased $1.4 million.

As more fully described in Note 3 - Loans in the accompanying consolidated financial statements, we measure 
expected  credit  losses  over  the  life  of  each  loan  utilizing  a  combination  of  models  which  measure  probability  of 
default and loss given default, among other things. The measurement of expected credit losses is impacted by loan/
borrower attributes and certain macroeconomic variables. Models are adjusted to reflect the current impact of certain 
macroeconomic variables as well as their expected changes over a reasonable and supportable forecast period.

In estimating expected credit losses as of December 31, 2021, we utilized the Moody’s Analytics December 2021 
Consensus  Scenario  (the  “December  2021  Consensus  Scenario”)  to  forecast  the  macroeconomic  variables  used  in 
our models. The December 2021 Consensus Scenario was based on the review of a variety of surveys of baseline 
forecasts of the U.S. economy. The December 2021 Consensus Scenario projections included, among other things, 
(i)  U.S.  Gross  Domestic  Product  (“GDP”)  annualized  quarterly  growth  rate  of  6.4%  in  the  first  quarter  of  2022, 
followed by annualized quarterly growth rates in the range of 3.8% to 5.4% during the remainder of 2022 and an 
average annualized growth rate of 4.8% through the end of the forecast period in the fourth quarter of 2023; (ii) U.S. 
unemployment rate of 4.3% in the first quarter of 2022 improving to 3.7% by the end of the forecast period in the 
fourth quarter of 2023 with Texas unemployment rates slightly higher at those dates; and (iii) projected average 10 
year Treasury rate of 1.59% in the first quarter of 2022, increasing to average projected rates of 1.75% during the 
remainder of 2022 and 2.10% in 2023. Furthermore, the December 2021 Consensus Scenario projects an average oil 
price in the range of approximately $62 to $66 per barrel through the end of the forecast period in the fourth quarter 
of 2023. 

In estimating expected credit losses as of December 31, 2020, we utilized the Moody’s Analytics December 2020 
BL Baseline Scenario (the “December BL Scenario”) to forecast the macroeconomic variables used in our models. 
The  December  BL  Scenario  was  based  on  the  review  of  a  variety  of  surveys  of  baseline  forecasts  of  the  U.S. 
economy. The December BL Scenario projections included, among other things, (i) U.S. Gross Domestic Product 
(“GDP”) annualized quarterly growth rate of 4.6% for the fourth quarter of 2020 followed by projected annualized 
quarterly growth rates in the range of approximately 3.0% to 8.0% during 2021 and 6.0% to 7.5% through the end of 
the forecast period in the fourth quarter of 2022; (ii) a U.S. unemployment rate of 6.7% in the fourth quarter of 2020 

63

and an average projected rate of 7.0% in 2021 and 6.0% in 2022, with the fourth quarter of 2022 projected to be 
5.4% (Texas unemployment rates were projected to be slightly less for those periods); and (iii) an average 10 year 
Treasury rate of 0.79% in the fourth quarter of 2020, increasing to an average projected rate of 1.05% in 2021 and 
2.04% in 2022. The December BL Scenario also projected average oil prices of $40 per barrel in the fourth quarter 
of 2020, $45 per barrel on average for the year in 2021 and $55 per barrel on average for the year in 2022, with the 
fourth quarter of 2022 projected to be $59 per barrel.

The overall loan portfolio, excluding PPP loans which are fully guaranteed by the SBA, as of December 31, 2021 
increased  $860.1  million,  or  5.7%,  compared  to  December  31,  2020.  This  increase  included  a  $556.1  million,  or 
7.9%,  increase  in  commercial  real  estate  loans,  a  $409.6  million,  or  8.3%,  increase  in  commercial  and  industrial 
loans  and  a  $80.0  million,  or  6.0%,  increase  in  consumer  real  estate  loans  partly  offset  by  a  $157.4  million,  or 
12.7%, decrease in energy loans and a $28.3 million, or 5.6%, decrease in consumer and other loans. The weighted 
average risk grade for commercial and industrial loans decreased to 6.22 at December 31, 2021 compared to 6.45 at 
December 31, 2020. Commercial and industrial loans graded “watch” and “special mention” (risk grades 9 and 10) 
decreased  $135.2  million  during  2021  while  classified  commercial  and  industrial  loans  decreased  $12.9  million. 
Classified  loans  consist  of  loans  having  a  risk  grade  of  11,  12  or  13.  The  weighted-average  risk  grade  for  energy 
loans  decreased  to  6.06  at  December  31,  2021  from  6.85  at  December  31,  2020.  The  decrease  in  the  weighted 
average risk grade was primarily related to a $141.6 million decrease in energy loans graded “watch” and “special 
mention”  (risk  grades  9  and  10)  and  a  $56.1  million  decrease  in  classified  energy  loans.  Pass  grade  energy  loans 
increased $40.2 million while the weighted-average risk grade of pass grade energy loans decreased slightly from 
5.99  at  December  31,  2020  to  5.78  at  December  31,  2021.  The  weighted  average  risk  grade  for  commercial  real 
estate loans decreased from 7.32 at December 31, 2020 to 7.19 at December 31, 2021. Pass grade commercial real 
estate loans increased $679.2 million while commercial real estate loans graded as “watch” and “special mention” 
decreased $62.8 million and classified commercial real estate loans decreased $60.3 million.

As  noted  above  our  credit  loss  models  utilized  the  economic  forecasts  in  the  Moody’s  Consensus  Scenario  for 
December  2021  for  our  estimated  expected  credit  losses  as  of  December  31,  2021  and  the  Moody’s  Baseline 
Scenario for December 2020 for our estimate of expected credit losses as of December 31, 2020. We qualitatively 
adjusted  the  model  results  based  on  these  scenarios  for  various  risk  factors  that  are  not  considered  within  our 
modeling processes but are nonetheless relevant in assessing the expected credit losses within our loan pools. These 
Q-Factor and other qualitative adjustments are discussed below.

Q-Factor  adjustments  are  based  upon  management  judgment  and  current  assessment  as  to  the  impact  of  risks 
related  to  changes  in  lending  policies  and  procedures;  economic  and  business  conditions;  loan  portfolio  attributes 
and  credit  concentrations;  and  external  factors,  among  other  things,  that  are  not  already  captured  within  the 
modeling inputs, assumptions and other processes. Management assesses the potential impact of such items within a 
range of severely negative impact to positive impact and adjusts the modeled expected credit loss by an aggregate 
adjustment percentage based upon the assessment. As a result of this assessment as of December 31, 2021, modeled 
expected credit losses were adjusted upwards by a weighted-average Q-Factor adjustment of approximately 2.3%, 
up  from  approximately  1.2%  at  December  31,  2020.  The  weighted-average  Q-Factor  adjustment  at  December  31, 
2021  was  based  on  a  limited  negative  expected  impact  on  our  commercial  loan  portfolios  related  to  changes  in 
lending  policies  procedures  and  underwriting  standards  and  changes  in  loan  portfolio  concentrations;  a  negative 
expected  impact  associated  with  national,  regional  and  local  economic  and  business  conditions  and  developments 
that affect the collectability of loans; a severely negative expected impact from other risk factors associated with our 
commercial  real  estate  construction  and  land  loan  portfolios,  particularly  the  risks  related  to  expected  extensions; 
and no impact to changes in loan portfolio attributes, changes in risk grades, changes in the volumes and severity of 
loan delinquencies and adverse classifications and potential deterioration of collateral values. The weighted-average 
Q-Factor adjustment at December 31, 2020 was based on a positive expected impact related to changes in lending 
policies, procedures and underwriting standards; a limited negative expected impact associated with changes in loan 
portfolio  attributes  and  concentrations,  changes  in  risk  grades,  changes  in  the  volumes  and  severity  of  loan 
delinquencies  and  adverse  classifications  and  potential  deterioration  of  collateral  values;  and  a  severely  negative 
expected  impact  from  other  risk  factors  associated  with  our  commercial  real  estate  construction  and  land  loan 
portfolios, particularly the risks related to expected extensions.

In the first quarter of 2020, unprecedented economic conditions due to the COVID-19 pandemic and oil and gas 
price volatility resulted in significant spikes in the unemployment rate and the level of unemployment claims as well 
as severe declines in the level of the U.S. and Texas GDPs, among other things. In some cases, our expected credit 
loss models consider these economic variables on a three- to four-quarter lag basis. As of December 31, 2021, the 

64

significant spikes in several of these variables are no longer impacting our model results; however, as the economy 
has  entered  recovery,  the  models  are  now  being  impacted  by  exceptionally  positive  changes  in  certain  variables 
which  has  resulted  in  lower  estimates  of  expected  credit  losses.  Notwithstanding  the  foregoing,  management 
believes there are still significant headwinds impacting the recovery of the U.S. and Texas economies and certain 
categories  of  our  loan  portfolio.  As  a  result,  we  have  provided  additional  qualitative  adjustments  for  certain 
categories of loans, as further described below.

As  of  December  31,  2020,  we  provided  an  additional  qualitative  adjustment  for  energy  production  loans.  This 
adjustment  was  estimated  based  on  borrowing  base  determinations  for  our  energy  production  loans  using  current 
engineering valuations. We also performed an analysis of our customers' secondary sources of capital. As a result of 
the estimated borrowing base deficiencies for the identified credits, we provided an additional qualitative adjustment 
of approximately $21.1 million for energy production loans at December 31, 2020. Using a similar methodology, we 
determined that a similar qualitative adjustment was not necessary as of December 31, 2021 as there were no longer 
any significant borrowing base deficiencies within the energy production portfolio as a result of higher market prices 
for oil and gas and lower line balances on production loans. Nonetheless, as of December 31, 2021, we provided an 
additional  qualitative  adjustment  for  energy  loans  totaling  $5.2  million  to  address  the  risk  associated  with 
relationship exposure concentrations within the energy loan portfolio, as further discussed below.

Our  Commercial  Real  Estate  Oversight  Council,  in  its  oversight  and  assessment  of  the  credit  quality  of  our 
commercial  real  estate  loan  portfolios,  believes  these  portfolios  continue  to  have  an  elevated  level  of  risk 
notwithstanding recent economic stimulus efforts by federal and state governments. As of December 31, 2021, we 
provided  additional  qualitative  adjustments  totaling  $127.2  million  for  various  categories  of  our  commercial  real 
estate  loan  portfolio.  This  amount  includes  $67.3  million  for  non-owner-occupied  commercial  real  estate  loans, 
$40.5  million  for  owner-occupied  commercial  real  estate  loans  and  $19.4  million  for  commercial  real  estate 
construction  loans.  These  additional  qualitative  adjustments  are  largely  related  to  the  on-going  effects  of  the 
COVID-19  pandemic,  as  further  discussed  below,  and  to  compensate  for  the  effect  of  unusually  large  positive 
changes  in  certain  economic  variables  used  by  our  credit  loss  models.  The  COVID-19  pandemic  has  also  been  a 
catalyst for the evolution of various remote work options which could impact the long-term performance of some 
types of office properties within our commercial real estate portfolio. Furthermore, management believes that there 
are still significant headwinds impacting the recovery of the U.S. and Texas economies and certain categories of our 
loan portfolio. These additional qualitative adjustments also include $2.6 million to address the risk associated with 
relationship exposure concentrations within our commercial real estate loan portfolio, as further discussed below.

The  COVID-19  pandemic  has  resulted  in  a  significant  decrease  in  commercial  activity  throughout  the  State  of 
Texas as well as nationally. Efforts to limit the spread of COVID-19 led to the closure of non-essential businesses, 
travel restrictions, supply chain disruptions and prohibitions on public gatherings, among other things, throughout 
many parts of the United States and, in particular, the markets in which we operate. Nonetheless, by late 2020, the 
markets  in  which  we  operate  had  substantially  reopened.  We  lend  to  customers  operating  in  certain  industries 
(detailed in the table below) that have been, and are expected to continue to be, more significantly impacted by the 
effects of the COVID-19 pandemic. We are continuing to monitor customers in these industries closely. In assessing 
these  portfolios  for  an  additional  qualitative  adjustment,  we  performed  a  comprehensive  review  of  the  financial 
condition and overall outlook of the borrowers within these portfolios. Based on this analysis, we determined that 
there continues to be an elevated level of risk associated with these industries. As a result, we provided an additional 
qualitative adjustment related to the effects of the COVID-19 pandemic totaling $45.2 million as of December 31, 
2021,  of  which  $40.5  million  was  allocated  to  commercial  real  estate  loans  and  $4.7  million  was  allocated  to 
commercial and industrial loans. These amounts are included in the totals detailed above. As of December 31, 2020, 
we  provided  a  similar  additional  qualitative  adjustment  totaling  $47.1  million,  which,  for  the  most  part,  was 
allocated to commercial real estate loans.

As  of  December  31,  2021,  we  provided  an  additional  qualitative  adjustment  for  our  commercial  and  industrial 
loan portfolio totaling $13.7 million, of which $4.7 million was included in the $45.2 million additional qualitative 
adjustment  for  COVID-19  impacted  industries  discussed  above.  The  adjustment  also  included  $5.0  million  to 
address  the  risk  associated  with  relationship  exposure  concentrations  within  our  commercial  and  industrial  loan 
portfolio, as further discussed below. Lastly, the adjustment included $4.0 million to address the risk associated with 
the  long-term  sustainability  of  borrowers  within  our  small  business  commercial  and  industrial  loan  portfolio.  The 
majority of these borrowers have been bolstered by PPP funding from the SBA which has helped them to sustain 
their  operations  amid  on-going  pandemic-related  shutdowns  and  other  restrictions.  Nonetheless,  management 
believes there is an elevated level of risk associated with the long-term viability of many of these businesses when 
this government supplemented funding runs out. Furthermore, on March 27, 2021, the COVID-19 Bankruptcy Relief 
Extension Act of 2021 was enacted, extending the bankruptcy relief provisions enacted in the CARES Act of 2020 
until  March  27,  2022.  These  provisions  provide  financially  distressed  small  businesses  and  individuals  greater 
access to bankruptcy relief. In that regard, we also provided an additional qualitative adjustment for our consumer 
and other loan portfolio totaling $1.4 million in light of the level of unsecured loans within this portfolio and other 
risk factors.

As of December 31, 2021, we allocated $12.8 million to address the risk associated with relationship exposure 
concentrations within our loan portfolio. Of this amount, $5.2 million was allocated to energy loans, $5.0 million 
was  allocated  to  commercial  and  industrial  loans  and  $2.6  million  was  allocated  to  commercial  real  estate  loans. 
Management  has  observed  through  industry  research  that  the  degree  to  which  expected  credit  losses  fluctuate  is 
directly  related  to  the  degree  to  which  a  loan  portfolio  is  concentrated  or  diversified.  A  highly  concentrated  loan 
portfolio is more likely to exhibit concentrated losses compared to a well diversified loan portfolio where segments 
are  exposed  to  relatively  uncorrelated  factors.  The  variations  in  loan  portfolio  concentrations  over  time  cause 
expected credit losses within our existing portfolio to differ from historical loss experience. Given that the allowance 
for  credit  losses  on  loans  reflects  expected  credit  losses  within  our  loan  portfolio  and  the  fact  that  these  expected 
credit  losses  are  uncertain  as  to  nature,  timing  and  amount,  management  believes  that  segments  with  higher 
concentration risk are more likely to experience a high loss event. Due to the fact that a significant portion of our 
loan portfolio is concentrated in large credit relationships and because of large, concentrated credit losses in recent 
years, management made the aforementioned qualitative adjustments, which were based upon statistical analysis, to 
address the risk associated with the such a relationship deteriorating to a loss event.

We recorded a net credit loss benefit related to loans totaling $6.1 million for 2021 compared to a net credit loss 
expense related to loans totaling $237.0 million in 2020 and $33.8 million in 2019. The net credit loss benefit related 
to loans during 2021 primarily reflects improvements in forecasted economic conditions and oil price trends relative 
to  the  prevailing  conditions  in  2020  as  well  as  a  decrease  in  net  charge-offs.  Credit  loss  expense  related  to  loans 
during  2020  reflected  the  uncertain  future  impacts  associated  with  the  COVID-19  pandemic  and  the  significant 
volatility in oil prices as well as the level of net charge-offs, the expected deterioration in credit quality and other 
changes  within  the  loan  portfolio.  Credit  loss  expense  during  2019  was  calculated  under  our  prior  incurred  loss 
methodology  and  primarily  reflected  the  level  of  net  charge-offs  and  specific  valuation  allowances  as  well  as  the 
impact  of  the  overall  growth  in  the  loan  portfolio  since  previous  year-end.  The  ratio  of  the  allowance  for  credit 
losses on loans to total loans was 1.52% (1.56% excluding PPP loans) at December 31, 2021 compared to 1.51% 
(1.75%  excluding  PPP  loans)  at  December  31,  2020  and  0.90%  at  December  31,  2019.  Management  believes  the 
recorded amount of the allowance for credit losses on loans is appropriate based upon management’s best estimate 
of  current  expected  credit  losses  within  the  existing  portfolio  of  loans.  Should  any  of  the  factors  considered  by 
management in making this estimate change, our estimate of current expect credit losses could also change, which 
could affect the level of future credit loss expense related to loans.

Allowance  for  Credit  Losses  -  Off-Balance-Sheet  Credit  Exposures.  The  allowance  for  credit  losses  on  off-
balance-sheet  credit  exposures  totaled  $50.3  million  and  $44.2  million  at  December  31,  2021  and  December  31, 
2020, respectively. The level of the allowance for credit losses on off-balance-sheet credit exposures depends upon 
the  volume  of  outstanding  commitments,  underlying  risk  grades,  the  expected  utilization  of  available  funds  and 
forecasted economic conditions impacting our loan portfolio. Credit loss expense related to off-balance-sheet credit 
exposures  totaled  $6.2  million  during  2021  compared  to  $4.3  million  during  2020.  The  increase  in  credit  loss 
expense primarily reflects an increase in overall off-balance-sheet credit exposures and the uncertain future impacts 
associated  with  COVID-19.  Credit  loss  expense  for  off-balancee-sheet  credit  exposures  in  2021  was  also  partly 
impacted by the down-grade of a large credit commitment within our SNC portfolio. No credit loss expense related 
to  off-balance-sheet  credit  exposures  was  recognized  during  2019  under  our  prior  incurred  loss  methodology. 
Further information regarding our policies and methodology used to estimate the allowance for credit losses on off-
balance-sheet credit exposures is presented in Note 8 - Off-Balance-Sheet Arrangements, Commitments, Guarantees 
and Contingencies in the accompanying notes to consolidated financial statements. 

Securities

The following tables summarize the maturity distribution schedule with corresponding weighted-average yields of 
securities held to maturity and securities available for sale as of December 31, 2021. Weighted-average yields have 
been computed on a fully taxable-equivalent basis using a tax rate of 21%. Mortgage-backed securities are included 
in maturity categories based on their stated maturity date. Expected maturities may differ from contractual maturities 
because  issuers  may  have  the  right  to  call  or  prepay  obligations.  Other  securities  classified  as  available  for  sale 
include stock in the Federal Reserve Bank and the Federal Home Loan Bank, which have no maturity date. These 
securities have been included in the total column only. Held-to-maturity securities are presented at amortized cost 
before any allowance for credit losses.

All  mortgage-backed  securities  included  in  the  above  tables  were  issued  by  U.S.  government  agencies  and 
corporations. At December 31, 2021, all of the securities in our municipal bond portfolio were issued by the State of 
Texas  or  political  subdivisions  or  agencies  within  the  State  of  Texas,  of  which  approximately  77.9%  are  either 
guaranteed by the Texas Permanent School Fund, which has a “triple-A” insurer financial strength rating, or secured 
by U.S. Treasury securities via defeasance of the debt by the issuers.

The  average  taxable-equivalent  yield  on  the  securities  portfolio  based  on  a  21%  tax  rate  was  3.29%  in  2021 
compared to 3.46% in 2020. Tax-exempt municipal securities totaled 64.2% of average securities in 2021 compared 
to 66.6% in 2020. The average yield on taxable securities was 1.97% in 2021 compared to 2.27% in 2020, while the 
average taxable-equivalent yield on tax-exempt securities was 4.06% in 2021 compared to 4.08% in 2020. See the

Average  deposits  increased  $7.0  billion,  or  22.4%,  in  2021  compared  to  2020.  The  most  significant  volume 
growth  during  2021  compared  to  2020  was  in  non-interest  bearing  deposits;  savings  and  interest  checking;  and 
money market deposits. The ratio of average interest-bearing deposits to total average deposits was 56.7% in 2021 
compared to 56.9% in 2020. The average cost of interest-bearing deposits and total deposits was 0.07% and 0.04% 
during  2021  compared  to  0.18%  and  0.10%  during  2020.  The  decrease  in  the  average  cost  of  interest-bearing 
deposits in 2021 as compared to 2020 was related to lower average interest rates paid on most of our interest-bearing 
deposit products as a result of lower average market interest rates.

Geographic Concentrations. The following table summarizes our average total deposit portfolio, as segregated by

Foreign  Deposits.  Mexico  has  historically  been  considered  a  part  of  the  natural  trade  territory  of  our  banking 
offices. Accordingly, U.S. dollar-denominated foreign deposits from sources within Mexico have traditionally been 
a significant source of funding. Average deposits from foreign sources, primarily Mexico, totaled $933.3 million in 
2021 and $824.9 million in 2020.

Brokered Deposits. From time to time, we have obtained interest-bearing deposits through brokered transactions 
including participation in the Certificate of Deposit Account Registry Service (“CDARS”). Brokered deposits were 
not significant during the reported periods.

Capital and Liquidity

Capital. Shareholders’ equity totaled $4.4 billion at December 31, 2021 and $4.3 billion at December 31, 2020. In 
addition to net income of $443.1 million, other sources of capital during 2021 included $54.4 million in proceeds 
from  stock  option  exercises  and  $12.8  million  related  to  stock-based  compensation.  Additionally,  we  issued  $1.7 
million  of  common  stock  held  in  treasury  to  our  401(k)  plan  in  connection  with  matching  contributions.  Uses  of 
capital  during  2021  included  $195.9  million  of  dividends  paid  on  preferred  and  common  stock,  an  other 
comprehensive loss, net of tax, of $165.7 million and  $3.9 million of treasury stock purchases.

The  accumulated  other  comprehensive  income/loss  component  of  shareholders’  equity  totaled  a  net,  after-tax, 
unrealized gain of $347.3 million at December 31, 2021 compared to a net, after-tax, unrealized gain $513.0 million 
at  December  31,  2020.  The  decrease  was  primarily  due  to  a  $183.6  million  net,  after-tax,  decrease  in  the  net 
unrealized gain on securities available for sale and securities transferred to held to maturity, partly offset by $17.9 
million related to a decrease in the net actuarial loss and reclassification adjustments related to our defined-benefit 
post retirement benefit plans.

Under  the  Basel  III  Capital  Rules,  we  elected  to  opt-out  of  the  requirement  to  include  most  components  of 
accumulated other comprehensive income in regulatory capital. Accordingly, amounts reported as accumulated other 
comprehensive  income/loss  related  to  securities  available  for  sale,  effective  cash  flow  hedges  and  defined  benefit 
post-retirement benefit plans do not increase or reduce regulatory capital and are not included in the calculation of 
risk-based  capital  and  leverage  ratios.  In  connection  with  the  adoption  of  ASC  326  on  January  1,  2020,  we  also 
elected to exclude, for a transitional period, the effects of credit loss accounting under CECL in the calculation of 
our  regulatory  capital  and  regulatory  capital  ratios.  Regulatory  agencies  for  banks  and  bank  holding  companies 
utilize capital guidelines designed to measure capital and take into consideration the risk inherent in both on-balance 
sheet  and  off-balance  sheet  items.  See  Note  9  -  Capital  and  Regulatory  Matters  in  the  accompanying  notes  to 
consolidated financial statements elsewhere in this report.

We paid quarterly dividends of $0.72, $0.72, $0.75 and $0.75 per common share during the first, second, third 
and  fourth  quarters  of  2021,  respectively,  and  quarterly  dividends  of  $0.71,  $0.71,  $0.71  and  $0.72  per  common 
share during the first, second, third and fourth quarters of 2020, respectively. This equates to a dividend payout ratio 
of 43.3% in 2021 and 55.8% in 2020. The amount of dividend, if any, we may pay may be limited as more fully 
discussed in Note 9 - Capital and Regulatory Matters in the accompanying notes to consolidated financial statements 
elsewhere in this report.

Preferred Stock. On March 16, 2020, we redeemed all 6,000,000 shares of our 5.375% Non-Cumulative Perpetual 
Preferred  Stock,  Series  A,  (“Series  A  Preferred  Stock”)  at  a  redemption  price  of  $25  per  share,  or  an  aggregate 
redemption  of  $150.0  million.  On  November  19,  2020  we  issued  150,000  shares,  or  $150.0  million  in  aggregate 
liquidation  preference,  of  our  4.450%  Non-Cumulative  Perpetual  Preferred  Stock,  Series  B,  par  value  $0.01  and 
liquidation preference $1,000 per share (“Series B Preferred Stock”). Each share of Series B Preferred Stock issued 
and outstanding is represented by 40 depositary shares, each representing a 1/40th ownership interest in a share of 
the Series B Preferred Stock (equivalent to a liquidation preference of $25 per share). Additional details about our 
preferred stock are included in Note 9 - Capital and Regulatory Matters in the accompanying notes to consolidated 
financial statements elsewhere in this report.

Stock  Repurchase  Plans.  From  time  to  time,  our  board  of  directors  has  authorized  stock  repurchase  plans.  In 
general,  stock  repurchase  plans  allow  us  to  proactively  manage  our  capital  position  and  return  excess  capital  to 
shareholders. Shares purchased under such plans also provide us with shares of common stock necessary to satisfy 
obligations related to stock compensation awards. On January 26, 2022, our board of directors authorized a $100.0 
million stock repurchase plan, allowing us to repurchase shares of our common stock over a one-year period from 
time to time at various prices in the open market or through private transactions. Under prior stock repurchase plans, 
we  repurchased,  177,834  shares  at  a  total  cost  of  $13.7  million  during  2020  and  699,031  shares  at  a  total  cost  of 
$67.2  million  during  2019.  No  shares  were  repurchased  under  a  stock  repurchase  plan  during  2021.  See  Part  II, 
Item  5  -  Market  for  Registrant’s  Common  Equity,  Related  Stockholder  Matters  and  Issuer  Purchases  of  Equity 
Securities, elsewhere in this report.

Liquidity.  Liquidity  measures  the  ability  to  meet  current  and  future  cash  flow  needs  as  they  become  due.  The 
liquidity  of  a  financial  institution  reflects  its  ability  to  meet  loan  requests,  to  accommodate  possible  outflows  in 
deposits and to take advantage of interest rate market opportunities. The ability of a financial institution to meet its 
current financial obligations is a function of its balance sheet structure, its ability to liquidate assets and its access to 
alternative  sources  of  funds.  The  objective  of  our  liquidity  management  is  to  manage  cash  flow  and  liquidity 
reserves so that they are adequate to fund our operations and to meet obligations and other commitments on a timely 
basis  and  at  a  reasonable  cost.  We  seek  to  achieve  this  objective  and  ensure  that  funding  needs  are  met  by 
maintaining an appropriate level of liquid funds through asset/liability management, which includes managing the 
mix and time to maturity of financial assets and financial liabilities on our balance sheet. Our liquidity position is 
enhanced by our ability to raise additional funds as needed in the wholesale markets.

70

Asset liquidity is provided by liquid assets which are readily marketable or pledgeable or which will mature in the 
near future. Liquid assets include cash, interest-bearing deposits in banks, securities available for sale, maturities and 
cash  flow  from  securities  held  to  maturity,  and  federal  funds  sold  and  resell  agreements.  Liability  liquidity  is 
provided by access to funding sources which include core deposits and correspondent banks in our natural trade area 
that maintain accounts with and sell federal funds to Frost Bank, as well as federal funds purchased and repurchase 
agreements from upstream banks and deposits obtained through financial intermediaries.

Our liquidity position is continuously monitored and adjustments are made to the balance between sources and 
uses  of  funds  as  deemed  appropriate.  Liquidity  risk  management  is  an  important  element  in  our  asset/liability 
management process. We regularly model liquidity stress scenarios to assess potential liquidity outflows or funding 
problems resulting from economic disruptions, volatility in the financial markets, unexpected credit events or other 
significant occurrences deemed problematic by management. These scenarios are incorporated into our contingency 
funding plan, which provides the basis for the identification of our liquidity needs. As of December 31, 2021, we 
had approximately $15.9 billion held in an interest-bearing account at the Federal Reserve. We also have the ability 
to borrow funds as a member of the Federal Home Loan Bank (“FHLB”). As of December 31, 2021, based upon 
available,  pledgeable  collateral,  our  total  borrowing  capacity  with  the  FHLB  was  approximately  $3.1  billion. 
Furthermore, at December 31, 2021, we had approximately $9.3 billion in securities that were unencumbered by a 
pledge and could be used to support additional borrowings through repurchase agreements or the Federal Reserve 
discount window, as needed. As of December 31, 2021, management is not aware of any events that are reasonably 
likely to have a material adverse effect on our liquidity, capital resources or operations. In addition, management is 
not aware of any regulatory recommendations regarding liquidity that would have a material adverse effect on us.

In the ordinary course of business we have entered into contractual obligations and have made other commitments 
to  make  future  payments.  Refer  to  the  accompanying  notes  to  consolidated  financial  statements  elsewhere  in  this 
report  for  the  expected  timing  of  such  payments  as  of  December  31,  2021.  These  include  payments  related  to 
(i) long-term borrowings (Note 7 - Borrowed Funds), (ii) operating leases (Note 4 - Premises and Equipment and 
Lease  Commitments),  (iii)  time  deposits  with  stated  maturity  dates  (Note  6  -  Deposits)  and  (iv)  commitments  to 
extend  credit  and  standby  letters  of  credit  (Note  8  -  Off-Balance-Sheet  Arrangements,  Commitments,  Guarantees 
and Contingencies). 

Since  Cullen/Frost  is  a  holding  company  and  does  not  conduct  operations,  its  primary  sources  of  liquidity  are 
dividends  upstreamed  from  Frost  Bank  and  borrowings  from  outside  sources.  Banking  regulations  may  limit  the 
amount  of  dividends  that  may  be  paid  by  Frost  Bank.  See  Note  9  -  Capital  and  Regulatory  Matters  in  the 
accompanying  notes  to  consolidated  financial  statements  elsewhere  in  this  report  regarding  such  dividends.  At 
December 31, 2021, Cullen/Frost had liquid assets, including cash and resell agreements, totaling $471.9 million.

Regulatory and Economic Policies

Our business and earnings are affected by general and local economic conditions and by the monetary and fiscal 
policies of the United States government, its agencies and various other governmental regulatory authorities, among 
other  things.  The  Federal  Reserve  Board  regulates  the  supply  of  money  in  order  to  influence  general  economic 
conditions.  Among  the  instruments  of  monetary  policy  historically  available  to  the  Federal  Reserve  Board  are 
(i) conducting open market operations in United States government obligations, (ii) changing the discount rate on 
financial  institution  borrowings,  (iii)  imposing  or  changing  reserve  requirements  against  financial  institution 
deposits,  and  (iv)  restricting  certain  borrowings  and  imposing  or  changing  reserve  requirements  against  certain 
borrowings by financial institutions and their affiliates. These methods are used in varying degrees and combinations 
to affect directly the availability of bank loans and deposits, as well as the interest rates charged on loans and paid on 
deposits. For that reason alone, the policies of the Federal Reserve Board have a material effect on our earnings.

Governmental policies have had a significant effect on the operating results of commercial banks in the past and 
are expected to continue to do so in the future; however, we cannot accurately predict the nature, timing or extent of 
any effect such policies may have on our future business and earnings.

Accounting Standards Updates

financial statements.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The disclosures set forth in this item are qualified by Item 1A. Risk Factors and the section captioned “Forward-
Looking  Statements  and  Factors  that  Could  Affect  Future  Results”  included  in  Item  7.  Management’s  Discussion 
and Analysis of Financial Condition and Results of Operations, of this report, and other cautionary statements set 
forth elsewhere in this report.

Market  risk  refers  to  the  risk  of  loss  arising  from  adverse  changes  in  interest  rates,  foreign  currency  exchange 
rates, commodity prices, and other relevant market rates and prices, such as equity prices. The risk of loss can be 
assessed from the perspective of adverse changes in fair values, cash flows, and future earnings. Due to the nature of 
our operations, we are primarily exposed to interest rate risk and, to a lesser extent, liquidity risk.

Interest  rate  risk  on  our  balance  sheets  consists  of  reprice,  option,  and  basis  risks.  Reprice  risk  results  from 
differences in the maturity, or repricing, of asset and liability portfolios. Option risk arises from “embedded options” 
present in many financial instruments such as loan prepayment options, deposit early withdrawal options and interest 
rate  options.  These  options  allow  customers  opportunities  to  benefit  when  market  interest  rates  change,  which 
typically  results  in  higher  costs  or  lower  revenue  for  us.  Basis  risk  refers  to  the  potential  for  changes  in  the 
underlying  relationship  between  market  rates  and  indices,  which  subsequently  result  in  a  narrowing  of  the  profit 
spread  on  an  earning  asset  or  liability.  Basis  risk  is  also  present  in  administered  rate  liabilities,  such  as  savings 
accounts,  negotiable  order  of  withdrawal  accounts,  and  money  market  accounts  where  historical  pricing 
relationships to market rates may change due to the level or directional change in market interest rates.

We seek to avoid fluctuations in our net interest margin and to maximize net interest income within acceptable 
levels of risk through periods of changing interest rates. Accordingly, our interest rate sensitivity and liquidity are 
monitored  on  an  ongoing  basis  by  our  Asset  and  Liability  Committee  (“ALCO”),  which  oversees  market  risk 
management and establishes risk measures, limits and policy guidelines for managing the amount of interest rate risk 
and its effect on net interest income and capital. A variety of measures are used to provide for a comprehensive view 
of the magnitude of interest rate risk, the distribution of risk, the level of risk over time and the exposure to changes 
in certain interest rate relationships.

We utilize an earnings simulation model as the primary quantitative tool in measuring the amount of interest rate 
risk  associated  with  changing  market  rates.  The  model  quantifies  the  effects  of  various  interest  rate  scenarios  on 
projected  net  interest  income  and  net  income  over  the  next  12  months.  The  model  measures  the  impact  on  net 
interest  income  relative  to  a  flat-rate  case  scenario  of  hypothetical  fluctuations  in  interest  rates  over  the  next 
12  months.  These  simulations  incorporate  assumptions  regarding  balance  sheet  growth  and  mix,  pricing  and  the 
repricing  and  maturity  characteristics  of  the  existing  and  projected  balance  sheet.  The  impact  of  interest  rate 
derivatives,  such  as  interest  rate  swaps,  caps  and  floors,  is  also  included  in  the  model.  Other  interest  rate-related 
risks such as prepayment, basis and option risk are also considered.

ALCO continuously monitors and manages the balance between interest rate-sensitive assets and liabilities. The 
objective  is  to  manage  the  impact  of  fluctuating  market  rates  on  net  interest  income  within  acceptable  levels.  In 
order to meet this objective, management may lengthen or shorten the duration of assets or liabilities or enter into 
derivative contracts to mitigate potential market risk.

For modeling purposes, as of December 31, 2021, the model simulations projected that 100 and 200 basis point 
ratable  increases  in  interest  rates  would  result  in  positive  variances  in  net  interest  income  of  2.8%  and  7.1%, 
respectively, relative to the flat-rate case over the next 12 months, while a 25 basis point ratable decrease in interest 
rates would result in a negative variance in net interest income of 3.0% relative to the flat-rate case over the next 
12 months. As of December 31, 2020, the model simulations projected that 100 and 200 basis point ratable increases 
in interest rates would result in positive variances in net interest income of 2.3% and 6.2%, respectively, relative to 
the flat-rate case over the next 12 months, while a 25 basis point ratable decrease in interest rates would result in a 
negative  variance  in  net  interest  income  of  1.8%  relative  to  the  flat-rate  case  over  the  next  12  months.  Both  the 
December 31, 2021 and 2020 model simulations for increased interest rates were impacted by the assumption, for 
modeling purposes, that we will begin to pay interest on commercial demand deposits (those not already receiving 
an  earnings  credit  rate)  in  the  first  quarters  of  2022  and  2021,  respectively,  as  further  discussed  below.  The 
likelihood of a decrease in interest rates beyond 25 basis points as of December 31, 2021 and 2020 was considered 
to be remote given prevailing interest rate levels.

72

The model simulations as of December 31, 2021 indicate that our projected balance sheet is more asset sensitive 
in comparison to our balance sheet as of December 31, 2020. The increased asset sensitivity was primarily due to an 
increase in the relative proportion of interest-bearing deposits (primarily amounts held by us in an interest-bearing 
account at the Federal Reserve) to projected average interest-earning assets. Such interest-bearing deposits are more 
immediately impacted by changes in interest rates in comparison to our other categories of earning assets.

We do not currently pay interest on a significant portion of our commercial demand deposits. Any interest rate 
that would ultimately be paid on these commercial demand deposits would likely depend upon a variety of factors, 
some  of  which  are  beyond  our  control.  Our  modeling  simulations  as  of  December  31,  2021  and  2020  assume  a 
slightly  aggressive  pricing  structure  with  regards  to  interest  payments  on  commercial  demand  deposits  (those  not 
already receiving an earnings credit) with interest payments assumed to begin in the first quarters of 2022 and 2021, 
respectively.  This  pricing  structure  on  commercial  demand  deposits  assumes  a  deposit  pricing  beta  of  25%.  The 
pricing beta is a measure of how much deposit rates reprice, up or down, given a defined change in market rates. 

As of December 31, 2021, the effects of a 200 basis point increase and a 25 basis point decrease in interest rates 

on our derivative holdings would not result in a significant variance in our net interest income.

The  effects  of  hypothetical  fluctuations  in  interest  rates  on  our  securities  classified  as  “trading”  under  ASC 
Topic  320,  “Investments  -  Debt  and  Equity  Securities”  are  not  significant,  and,  as  such,  separate  quantitative 
disclosure is not presented.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Cullen/Frost Bankers, Inc.

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheets of Cullen/Frost Bankers, Inc. (the Company) as 
of December 31, 2021 and 2020, 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, 2021, and the 
related  notes  (collectively  referred  to  as  the  consolidated  financial  statements).  In  our  opinion,  the  consolidated 
financial statements present fairly, in all material respects, the financial position of the Company at December 31, 
2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended 
December 31, 2021, in conformity with U.S. generally accepted accounting principles.

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board 
(United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2021, 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 4, 2022 expressed an 
unqualified opinion thereon.

Adoption of New Accounting Standard

As  discussed  in  Notes  1  and  3  to  the  consolidated  financial  statements,  the  Company  changed  its  method  for 
accounting  for  credit  losses  on  loans  in  2020  due  to  the  adoption  of  Accounting  Standards  Update  (ASU)  No. 
2016-13,  Financial  Instruments  —  Credit  Losses  (Topic  326):  Measurement  of  Credit  Losses  on  Financial 
Instruments, and the related amendments.

Basis for Opinion 

These financial statements are the responsibility of the Company’s management. Our responsibility is to express 
an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered 
with  the  PCAOB  and  are  required  to  be  independent  with  respect  to  the  Company  in  accordance  with  the  U.S. 
federal  securities  laws  and  applicable  rules  and  regulations  of  the  Securities  and  Exchange  Commission  and  the 
PCAOB.

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

Critical Audit Matter

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

Allowances for Credit Losses

Description of the Matter

The  Company’s  loan  portfolio  totaled  $16.3  billion  as  of  December  31,  2021  and  the  associated  allowance  for 
credit losses on loans was $248.7 million. The Company’s unfunded loan commitments totaled $10.7 billion, with 
an associated allowance for credit loss of $50.3 million. Together these amounts represent the allowances for credit 
losses (“ACL”). As discussed in Notes 1, and 3 to the consolidated financial statements, in the cases of loans, the 
allowance  for  credit  losses  is  a  contra-asset  valuation  account,  calculated  in  accordance  with  ASC  326,  that  is 
deducted from the amortized cost basis of loans to present the net amount expected to be collected. As discussed in 
Notes 1, 3, and 8 to the consolidated financial statements, in the case of unfunded loan commitments, the allowance 
for credit losses is a liability account, calculated in accordance with ASC 326, reported as a component of accrued 
interest payable and other liabilities. The amount of each allowance account represented management’s best estimate 
of current expected credit losses on these financial instruments considering all available information, from internal 
and  external  sources,  relevant  to  assessing  exposure  to  credit  loss  over  the  contractual  term  of  the  instrument.  In 
calculating the allowance for credit losses, most loans were segmented into pools based upon similar characteristics 
and  risk  profiles.  For  each  loan  pool,  management  measured  expected  credit  losses  over  the  life  of  each  loan 
utilizing a combination of models which measured probability of default (“PD”), probability of attrition (“PA”), loss 
given  default  (“LGD”),  and  exposure  at  default  (“EAD”).  Modeled  expected  credit  losses  were  calculated  as  the 
product of PD (adjusted for attrition), LGD, and EAD. PD and PA were estimated by analyzing internally sourced 
data related to historical performance of each loan pool over a complete economic cycle. PD and PA were adjusted 
to reflect the current impact of certain macroeconomic variables as well as their expected changes over a reasonable 
and supportable forecast period. After the reasonable and supportable forecast period, the forecasted macroeconomic 
variables  were  reverted  to  their  historical  mean  utilizing  a  rational,  systematic  basis.  The  LGD  was  based  on 
historical  recovery  averages  for  each  loan  pool,  adjusted  to  reflect  the  current  impact  of  certain  macroeconomic 
variables as well as their expected changes over the reasonable and supportable forecast period. EAD was estimated 
using a linear regression model that estimates the average percentage of the loan balance that remains at the time of 
default. In some cases, management determined that an individual loan exhibited unique risk characteristics which 
differentiated the loan from other loans with the identified loan pools. In such cases, the loans were evaluated for 
expected credit losses on an individual basis and excluded from the collective evaluation. Management qualitatively 
adjusted model results for risk factors that were not considered within the modeling processes but were nonetheless 
relevant in assessing the expected credit losses within the loan pools. These qualitative factor adjustments modified 
management’s  estimate  of  expected  credit  losses  by  a  calculated  percentage  or  amount  based  upon  the  estimated 
level of risk.

Auditing  management’s  estimate  of  the  ACL  involved  a  high  degree  of  subjectivity  due  to  the  nature  of  the 
qualitative factor adjustments included in the allowances for credit losses and complexity due to the utilization of the 
PD, PA, LGD, and EAD models (the “Models”). Management’s identification and measurement of the qualitative 
factor adjustments is highly judgmental and could have a significant effect on the ACL.

How We Addressed the Matter in Our Audit

We  obtained  an  understanding  of  the  Company’s  process  for  establishing  the  ACL,  including  the  utilization  of 
Models  and  the  qualitative  factor  adjustments  of  the  ACL.  We  evaluated  the  design  and  tested  the  operating 
effectiveness of related controls over the reliability and accuracy of data used to calculate and estimate the various 
components  of  the  ACL,  the  accuracy  of  the  calculation  of  the  ACL,  management’s  review  and  approval  of 
methodologies  used  to  establish  the  ACL,  validation  procedures  over  the  Models,  analysis  of  changes  in  various 
components  of  the  ACL  relative  to  changes  in  the  Company’s  loan  portfolio  and  economy  and  evaluation  of  the 
overall reasonableness and appropriateness of the ACL. In doing so, we tested the operating effectiveness of review 
and  approval  controls  in  the  Company’s  governance  process  designed  to  identify  and  assess  the  qualitative  factor 
adjustments which is meant to measure expected credit losses associated with factors not captured fully in the other 
components of the ACL.

To  test  the  reasonableness  of  the  qualitative  factor  adjustments,  we  performed  audit  procedures  that  included, 
among others testing the appropriateness of the methodologies used by the Company to estimate the ACL, testing 
the completeness and accuracy of data and information used by the Company in estimating the components of the 
ACL, assessing the reasonableness of the Models, evaluating the appropriateness of assumptions used in estimating 
the  qualitative  factor  adjustments,  analyzing  the  changes  in  assumptions  and  various  components  of  the  ACL

Cullen/Frost Bankers, Inc.
Notes To Consolidated Financial Statements
(Table amounts in thousands, except share and per share amounts)

Note 1 - Summary of Significant Accounting Policies

Nature  of  Operations.  Cullen/Frost  Bankers,  Inc.  (“Cullen/Frost”)  is  a  financial  holding  company  and  a  bank 
holding  company  headquartered  in  San  Antonio,  Texas  that  provides,  through  its  subsidiaries,  a  broad  array  of 
products and services throughout numerous Texas markets. The terms “Cullen/Frost,” “the Corporation,” “we,” “us” 
and “our” mean Cullen/Frost Bankers, Inc. and its subsidiaries, when appropriate. In addition to general commercial 
and  consumer  banking,  other  products  and  services  offered  include  trust  and  investment  management,  insurance, 
brokerage, mutual funds, leasing, treasury management, capital markets advisory and item processing.

Basis  of  Presentation.  The  consolidated  financial  statements  include  the  accounts  of  Cullen/Frost  and  all  other 
entities  in  which  Cullen/Frost  has  a  controlling  financial  interest.  All  significant  intercompany  balances  and 
transactions  have  been  eliminated  in  consolidation.  The  accounting  and  financial  reporting  policies  we  follow 
conform,  in  all  material  respects,  to  accounting  principles  generally  accepted  in  the  United  States  and  to  general 
practices within the financial services industry.

We determine whether we have a controlling financial interest in an entity by first evaluating whether the entity is 
a  voting  interest  entity  or  a  variable  interest  entity  (“VIE”)  under  accounting  principles  generally  accepted  in  the 
United States. Voting interest entities are entities in which the total equity investment at risk is sufficient to enable 
the  entity  to  finance  itself  independently  and  provides  the  equity  holders  with  the  obligation  to  absorb  losses,  the 
right to receive residual returns and the right to make decisions about the entity’s activities. We consolidate voting 
interest  entities  in  which  we  have  all,  or  at  least  a  majority  of,  the  voting  interest.  As  defined  in  applicable 
accounting  standards,  VIEs  are  entities  that  lack  one  or  more  of  the  characteristics  of  a  voting  interest  entity.  A 
controlling financial interest in a VIE is present when an enterprise has both the power to direct the activities of the 
VIE that most significantly impact the VIE’s economic performance and an obligation to absorb losses or the right 
to  receive  benefits  that  could  potentially  be  significant  to  the  VIE.  The  enterprise  with  a  controlling  financial 
interest, known as the primary beneficiary, consolidates the VIE. Our wholly-owned subsidiary, Cullen/Frost Capital 
Trust  II,  is  a  VIE  for  which  we  are  not  the  primary  beneficiary  and,  as  such,  its  accounts  are  not  included  in  our 
consolidated financial statements.

Acquisitions are accounted for using the purchase method with the operating results of the acquired companies 

included with our results of operations since their respective dates of acquisition.

We  have  evaluated  subsequent  events  for  potential  recognition  and/or  disclosure  through  the  date  these 

consolidated financial statements were issued. 

Use  of  Estimates.  The  preparation  of  financial  statements  in  conformity  with  accounting  principles  generally 
accepted  in  the  United  States  requires  management  to  make  estimates  and  assumptions  that  affect  the  reported 
amounts  of  assets  and  liabilities  and  disclosure  of  contingent  assets  and  liabilities  at  the  date  of  the  financial 
statements.  Actual  results  could  differ  from  those  estimates.  The  allowance  for  credit  losses  on  loans  and  off-
balance-sheet  credit  exposures,  the  fair  values  of  financial  instruments  and  the  status  of  contingencies  are 
particularly subject to change.

Concentrations  and  Restrictions  on  Cash  and  Cash  Equivalents.  We  maintain  deposits  with  other  financial 
institutions  in  amounts  that  exceed  federal  deposit  insurance  coverage.  Furthermore,  federal  funds  sold  are 
essentially  uncollateralized  loans  to  other  financial  institutions.  Management  regularly  evaluates  the  credit  risk 
associated with the counterparties to these transactions and believes that we are not exposed to any significant credit 
risks on cash and cash equivalents.

As of December 31, 2021 and 2020, we had $110.3 million and $74.0 million in cash collateral on deposit with 
other  financial  institution  counterparties  to  interest  rate  swap  transactions.  Additionally,  prior  to  2021  we  were 
required  to  maintain  a  minimum  amount  cash  on  hand  or  on  deposit  with  the  Federal  Reserve  Bank  to  meet 
regulatory reserve and clearing requirements. This amount totaled $42.0 million at December 31, 2020.

Cash Flow Reporting. Cash and cash equivalents include cash, deposits with other financial institutions that have 
an initial maturity of less than 90 days when acquired by us, federal funds sold and resell agreements. Net cash flows 
are  reported  for  loans,  deposit  transactions  and  short-term  borrowings.  Additional  cash  flow  information  was  as 
follows:

Cash paid for interest
Cash paid for income tax

Repurchase/Resell Agreements. We purchase certain securities under agreements to resell. The amounts advanced 
under  these  agreements  represent  short-term  loans  and  are  reflected  as  assets  in  the  accompanying  consolidated 
balance sheets. The securities underlying these agreements are book-entry securities. We also sell certain securities 
under  agreements  to  repurchase.  The  agreements  are  treated  as  collateralized  financing  transactions  and  the 
obligations to repurchase securities sold are reflected as a liability in the accompanying consolidated balance sheets. 
The dollar amount of the securities underlying the agreements remains in the asset accounts.

Securities. Securities are classified as held to maturity and carried at amortized cost when management has the 
positive  intent  and  ability  to  hold  them  until  maturity.  Securities  to  be  held  for  indefinite  periods  of  time  are 
classified as available for sale and carried at fair value, with the unrealized holding gains and losses (those for which 
no  allowance  for  credit  losses  are  recorded)  reported  as  a  component  of  other  comprehensive  income,  net  of  tax. 
Securities held for resale in anticipation of short-term market movements are classified as trading and are carried at 
fair  value,  with  changes  in  unrealized  holding  gains  and  losses  included  in  income.  Management  determines  the 
appropriate classification of securities at the time of purchase. Securities with limited marketability, such as stock in 
the Federal Reserve Bank and the Federal Home Loan Bank, are carried at cost.

Interest income on securities includes amortization of purchase premiums and discounts. Premiums and discounts 
on securities are generally amortized using the interest method with a constant effective yield without anticipating 
prepayments,  except  for  mortgage-backed  securities  where  prepayments  are  anticipated.  Premiums  on  callable 
securities are amortized to their earliest call date. A security is placed on non-accrual status if (i) principal or interest 
has  been  in  default  for  a  period  of  90  days  or  more  or  (ii)  full  payment  of  principal  and  interest  is  not  expected. 
Interest  accrued  but  not  received  for  a  security  placed  on  non-accrual  status  is  reversed  against  interest  income. 
Gains and losses on sales are recorded on the trade date and are derived from the amortized cost of the security sold.

Loans. Loans are reported at the principal balance outstanding net of unearned discounts. Interest income on loans 
is reported on the level-yield method and includes amortization of deferred loan fees and costs over the terms of the 
individual loans to which they relate, or, in certain cases, over the average expected term for loans where deferred 
fees  and  costs  are  accounted  for  on  a  pooled  basis.  Net  loan  commitment  fees  or  costs  for  commitment  periods 
greater than one year are deferred and amortized into fee income or other expense on a straight-line basis over the 
commitment period. Income on direct financing leases is recognized on a basis that achieves a constant periodic rate 
of return on the outstanding investment. Further information regarding our accounting policies related to past due 
loans, non-accrual loans, impaired loans and troubled-debt restructurings is presented in Note 3 - Loans.

Allowance  for  Credit  Losses.  As  further  discussed  below,  we  adopted  Accounting  Standards  Update  (“ASU”) 
2016-13,  “Financial  Instruments  -  Credit  Losses  (Topic  326):  Measurement  of  Credit  Losses  on  Financial 
Instruments,” on January 1, 2020. Accounting Standards Codification (“ASC”) Topic 326 (“ASC 326”) replaced the 
previous “incurred loss” model for measuring credit losses, which encompassed allowances for current known and 
inherent  losses  within  the  portfolio,  with  an  “expected  loss”  model,  which  encompasses  allowances  for  losses 

83

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
expected to be incurred over the life of the portfolio. The new current expected credit loss (“CECL”) model requires 
the measurement of all expected credit losses for financial assets measured at amortized cost and certain off-balance-
sheet credit exposures based on historical experience, current conditions, and reasonable and supportable forecasts. 
In  connection  with  the  adoption  of  ASC  326,  we  revised  certain  accounting  policies  and  implemented  certain 
accounting policy elections. The revised accounting policies are described below. 

Allowance For Credit Losses - Held-to-Maturity Securities: The allowance for credit losses on held-to-maturity 
securities  is  a  contra-asset  valuation  account,  calculated  in  accordance  with  ASC  326,  that  is  deducted  from  the 
amortized cost basis of held-to-maturity securities to present management's best estimate of the net amount expected 
to  be  collected.  Held-to-maturity  securities  are  charged-off  against  the  allowance  when  deemed  uncollectible  by 
management.  Adjustments  to  the  allowance  are  reported  in  our  income  statement  as  a  component  of  credit  loss 
expense. Management measures expected credit losses on held-to-maturity securities on a collective basis by major 
security type with each type sharing similar risk characteristics and considers historical credit loss information that is 
adjusted  for  current  conditions  and  reasonable  and  supportable  forecasts.  Management  has  made  the  accounting 
policy  election  to  exclude  accrued  interest  receivable  on  held-to-maturity  securities  from  the  estimate  of  credit 
losses. Further information regarding our policies and methodology used to estimate the allowance for credit losses 
on held-to-maturity securities is presented in Note 2 - Securities.

Allowance  For  Credit  Losses  -  Available-for-Sale  Securities:  For  available-for-sale  securities  in  an  unrealized 
loss position, we first assess whether (i) we intend to sell or (ii) it is more likely than not that we will be required to 
sell the security before recovery of its amortized cost basis. If either case is affirmative, any previously recognized 
allowances are charged-off and the security's amortized cost is written down to fair value through income. If neither 
case is affirmative, the security is evaluated to determine whether the decline in fair value has resulted from credit 
losses or other factors. In making this assessment, management considers the extent to which fair value is less than 
amortized cost, any changes to the rating of the security by a rating agency and any adverse conditions specifically 
related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of 
cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the 
present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an 
allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the 
amortized  cost  basis.  Any  impairment  that  has  not  been  recorded  through  an  allowance  for  credit  losses  is 
recognized in other comprehensive income. Adjustments to the allowance are reported in our income statement as a 
component of credit loss expense. Management has made the accounting policy election to exclude accrued interest 
receivable  on  available-for-sale  securities  from  the  estimate  of  credit  losses.  Available-for-sale  securities  are 
charged-off against the allowance or, in the absence of any allowance, written down through income when deemed 
uncollectible by management or when either of the aforementioned criteria regarding intent or requirement to sell is 
met.

Prior  to  the  adoption  of  ASU  2016-13,  declines  in  the  fair  value  of  held-to-maturity  and  available-for-sale 
securities below their cost that were deemed to be other than temporary were reflected in earnings as realized losses. 
In  estimating  other-than-temporary  impairment  losses  prior  to  January  1,  2020,  management  considered,  among 
other things, (i) the length of time and the extent to which the fair value had been less than cost, (ii) the financial 
condition  and  near-term  prospects  of  the  issuer  and  (iii)  the  intent  and  our  ability  to  retain  our  investment  in  the 
issuer for a period of time sufficient to allow for any anticipated recovery in fair value.

Allowance for Credit Losses - Loans: The allowance for credit losses on loans is a contra-asset valuation account, 
calculated  in  accordance  with  ASC  326,  that  is  deducted  from  the  amortized  cost  basis  of  loans  to  present 
management's best estimate of the net amount expected to be collected. Loans are charged-off against the allowance 
when deemed uncollectible by management. Expected recoveries do not exceed the aggregate of amounts previously 
charged-off and expected to be charged-off. Adjustments to the allowance are reported in our income statement as a 
component of credit loss expense. Management has made the accounting policy election to exclude accrued interest 
receivable on loans from the estimate of credit losses. Further information regarding our policies and methodology 
used to estimate the allowance for credit losses on loans is presented in Note 3 - Loans.

Prior  to  the  adoption  of  ASU  2016-13,  the  allowance  for  credit  losses  on  loans  was  a  contra-asset  valuation 
account established through a provision for loan losses charged to expense, which represented management’s best 
estimate  of  inherent  losses  that  had  been  incurred  within  the  existing  portfolio  of  loans.  The  allowance  for  credit 
losses  on  loans  included  allowance  allocations  calculated  in  accordance  with  ASC  Topic  310,  “Receivables”  and 
allowance allocations calculated in accordance with ASC Topic 450, “Contingencies.” 

84

Allowance  For  Credit  Losses  -  Off-Balance-Sheet  Credit  Exposures:  The  allowance  for  credit  losses  on  off-
balance-sheet credit exposures is a liability account, calculated in accordance with ASC 326, representing expected 
credit  losses  over  the  contractual  period  for  which  we  are  exposed  to  credit  risk  resulting  from  a  contractual 
obligation to extend credit. No allowance is recognized if we have the unconditional right to cancel the obligation. 
The  allowance  is  reported  as  a  component  of  accrued  interest  payable  and  other  liabilities  in  our  consolidated 
balance  sheets.  Adjustments  to  the  allowance  are  reported  in  our  income  statement  as  a  component  of  credit  loss 
expense.  Further  information  regarding  our  policies  and  methodology  used  to  estimate  the  allowance  for  credit 
losses  on  off-balance-sheet  credit  exposures  is  presented  in  Note  8  -  Off-Balance-Sheet  Arrangements, 
Commitments, Guarantees and Contingencies.

Premises and Equipment. Land is carried at cost. Building and improvements, and furniture and equipment are 
carried  at  cost,  less  accumulated  depreciation,  computed  principally  by  the  straight-line  method  based  on  the 
estimated useful lives of the related property. Leasehold improvements are generally depreciated over the lesser of 
the term of the respective leases or the estimated useful lives of the improvements.

We  lease  certain  office  facilities  and  office  equipment  under  operating  leases.  We  also  own  certain  office 
facilities which we lease to outside parties under operating lessor leases; however, such leases are not significant. In 
2019, we adopted certain accounting standard updates related to accounting for leases as further discussed below. 
Under the new standards, for operating leases other than those considered to be short-term, we recognize lease right-
of-use assets and related lease liabilities. Such amounts are reported as components of premises and equipment and 
accrued interest payable and other liabilities, respectively, on our accompanying consolidated balance sheet. We do 
not recognize short-term operating leases on our balance sheet. A short-term operating lease has an original term of 
12 months or less and does not have a purchase option that is likely to be exercised. 

In  recognizing  lease  right-of-use  assets  and  related  lease  liabilities,  we  account  for  lease  and  non-lease 
components  (such  as  taxes,  insurance,  and  common  area  maintenance  costs)  separately  as  such  amounts  are 
generally  readily  determinable  under  our  lease  contracts.  Lease  payments  over  the  expected  term  are  discounted 
using our incremental borrowing rate referenced to the Federal Home Loan Bank Secure Connect advance rates for 
borrowings of similar term. We also consider renewal and termination options in the determination of the term of the 
lease. If it is reasonably certain that a renewal or termination option will be exercised, the effects of such options are 
included in the determination of the expected lease term. Generally, we cannot be reasonably certain about whether 
or not we will renew a lease until such time the lease is within the last two years of the existing lease term. However, 
renewal options related to our regional headquarters facilities or operations centers are evaluated on a case-by-case 
basis,  typically  in  advance  of  such  time  frame.  When  we  are  reasonably  certain  that  a  renewal  option  will  be 
exercised, we measure/remeasure the right-of-use asset and related lease liability using the lease payments specified 
for the renewal period or, if such amounts are unspecified, we generally assume an increase (evaluated on a case-by-
case basis in light of prevailing market conditions) in the lease payment over the final period of the existing lease 
term.

Foreclosed  Assets.  Assets  acquired  through  or  instead  of  loan  foreclosure  are  held  for  sale  and  are  initially 
recorded  at  fair  value  less  estimated  selling  costs  when  acquired,  establishing  a  new  cost  basis.  Write-downs 
occurring at acquisition are charged against the allowance for credit losses on loans. Foreclosed assets are included 
in  other  assets  in  the  accompanying  consolidated  balance  sheets  and  totaled  $3.4  million  and  $850  thousand  at 
December 31, 2021 and 2020. Regulatory guidelines require us to reevaluate the fair value of foreclosed assets on at 
least an annual basis. Our policy is to comply with the regulatory guidelines. If the fair value of the asset declines, a 
write-down  is  recorded  through  other  non-interest  expense  along  with  other  expenses  related  to  maintaining  the 
properties. The valuation of foreclosed assets is subjective in nature and may be adjusted in the future because of 
changes  in  economic  conditions.  Write-downs  of  foreclosed  assets  totaled  $14  thousand  during  2021  and  $231 
thousand  in  2020  while  there  were  no  write-downs  during  2019.  There  were  no  significant  concentrations  of  any 
properties, to which the aforementioned write-downs relate, in any single geographic region.

Goodwill. Goodwill represents the excess of the cost of businesses acquired over the fair value of the net assets 
acquired. Goodwill is assigned to reporting units and tested for impairment at least annually on October 1st, or on an 
interim basis if an event occurs or circumstances change that would more likely than not reduce the fair value of the 
reporting unit below its carrying value. See Note 5 - Goodwill and Other Intangible Assets.

85

Intangibles  and  Other  Long-Lived  Assets.  Intangible  assets  are  acquired  assets  that  lack  physical  substance  but 
can  be  distinguished  from  goodwill  because  of  contractual  or  other  legal  rights  or  because  the  asset  is  capable  of 
being sold or exchanged either on its own or in combination with a related contract, asset, or liability. Our intangible 
assets  relate  to  core  deposits,  non-compete  agreements  and  customer  relationships.  Intangible  assets  with  definite 
useful lives are amortized on an accelerated basis over their estimated life. Intangible assets with indefinite useful 
lives are not amortized until their lives are determined to be definite. Intangible assets, premises and equipment and 
other long-lived assets are tested for impairment whenever events or changes in circumstances indicate the carrying 
amount  of  the  assets  may  not  be  recoverable  from  future  undiscounted  cash  flows.  If  impaired,  the  assets  are 
recorded at fair value. See Note 5 - Goodwill and Other Intangible Assets.

Revenue  Recognition.  In  general,  for  revenue  not  associated  with  financial  instruments,  guarantees  and  lease 
contracts,  we  apply  the  following  steps  when  recognizing  revenue  from  contracts  with  customers:  (i)  identify  the 
contract, (ii) identify the performance obligations, (iii) determine the transaction price, (iv) allocate the transaction 
price  to  the  performance  obligations  and  (v)  recognize  revenue  when  a  performance  obligation  is  satisfied.  Our 
contracts with customers are generally short term in nature, typically due within one year or less or cancellable by us 
or  our  customer  upon  a  short  notice  period.  Performance  obligations  for  our  customer  contracts  are  generally 
satisfied  at  a  single  point  in  time,  typically  when  the  transaction  is  complete,  or  over  time.  For  performance 
obligations  satisfied  over  time,  we  primarily  use  the  output  method,  directly  measuring  the  value  of  the  products/
services transferred to the customer, to determine when performance obligations have been satisfied. We typically 
receive  payment  from  customers  and  recognize  revenue  concurrent  with  the  satisfaction  of  our  performance 
obligations. In most cases, this occurs within a single financial reporting period. For payments received in advance 
of  the  satisfaction  of  performance  obligations,  revenue  recognition  is  deferred  until  such  time  as  the  performance 
obligations  have  been  satisfied.  In  cases  where  we  have  not  received  payment  despite  satisfaction  of  our 
performance obligations, we accrue an estimate of the amount due in the period our performance obligations have 
been satisfied. For contracts with variable components, only amounts for which collection is probable are accrued. 
We  generally  act  in  a  principal  capacity,  on  our  own  behalf,  in  most  of  our  contracts  with  customers.  In  such 
transactions,  we  recognize  revenue  and  the  related  costs  to  provide  our  services  on  a  gross  basis  in  our  financial 
statements.  In  some  cases,  we  act  in  an  agent  capacity,  deriving  revenue  through  assisting  other  entities  in 
transactions  with  our  customers.  In  such  transactions,  we  recognize  revenue  and  the  related  costs  to  provide  our 
services on a net basis in our financial statements. These transactions recognized on a net basis primarily relate to 
insurance and brokerage commissions and fees derived from our customers' use of various interchange and ATM/
debit card networks.

Share-Based  Payments.  Compensation  expense  for  stock  options,  non-vested  stock  awards/stock  units  and 
deferred stock units is based on the fair value of the award on the measurement date, which, for us, is the date of the 
grant and is recognized ratably over the service period of the award. Compensation expense for performance stock 
units is based on the fair value of the award on the measurement date, which, for us, is the date of the grant and is 
recognized over the service period of the award based upon the probable number of units expected to vest. The fair 
value  of  stock  options  is  estimated  using  a  binomial  lattice-based  valuation  model.  The  fair  value  of  non-vested 
stock awards/stock units and deferred stock units is generally the market price of our stock on the date of grant. The 
fair value of performance stock units is generally the market price of our stock on the date of grant discounted by the 
present  value  of  the  dividends  expected  to  be  paid  on  our  common  stock  during  the  service  period  of  the  award 
because dividend equivalent payments on performance stock units are deferred until such time that the units vest and 
shares are issued. The impact of forfeitures of share-based payment awards on compensation expense is recognized 
as forfeitures occur.

Advertising Costs. Advertising costs are expensed as incurred.

Income Taxes. Income tax expense is the total of the current year income tax due or refundable and the change in 
deferred  tax  assets  and  liabilities  (excluding  deferred  tax  assets  and  liabilities  related  to  business  combinations  or 
components of other comprehensive income). Deferred tax assets and liabilities are the expected future tax amounts 
for  the  temporary  differences  between  carrying  amounts  and  tax  bases  of  assets  and  liabilities,  computed  using 
enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the expected amount most likely to 
be realized. Realization of deferred tax assets is dependent upon the generation of a sufficient level of future taxable 
income. Although realization is not assured, management believes it is more likely than not that all of the deferred 
tax assets will be realized. Interest and/or penalties related to income taxes are reported as a component of income 
tax expense. The income tax effects related to settlements of share-based payment awards are reported in earnings as 
an increase (or decrease) to income tax expense. See Note 13 - Income Taxes.

We file a consolidated income tax return with our subsidiaries. Federal income tax expense or benefit has been 

allocated to subsidiaries on a separate return basis.

Basic  and  Diluted  Earnings  Per  Common  Share.  Earnings  per  common  share  is  computed  using  the  two-class 
method  prescribed  under  ASC  Topic  260,  “Earnings  Per  Share.”  ASC  260  provides  that  unvested  share-based 
payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are 
participating  securities  and  shall  be  included  in  the  computation  of  earnings  per  share  pursuant  to  the  two-class 
method. We have determined that our outstanding non-vested stock awards/stock units and deferred stock units are 
participating securities.

Under the two-class method, basic earnings per common share is computed by dividing net earnings allocated to 
common  stock  by  the  weighted-average  number  of  common  shares  outstanding  during  the  applicable  period, 
excluding outstanding participating securities. Diluted earnings per common share is computed using the weighted-
average number of shares determined for the basic earnings per common share computation plus the dilutive effect 
of  stock  compensation  using  the  treasury  stock  method.  A  reconciliation  of  the  weighted-average  shares  used  in 
calculating basic earnings per common share and the weighted average common shares used in calculating diluted 
earnings per common share for the reported periods is provided in Note 10 - Earnings Per Common Share.

Comprehensive  Income.  Comprehensive  income  includes  all  changes  in  shareholders’  equity  during  a  period, 
except  those  resulting  from  transactions  with  shareholders.  Besides  net  income,  other  components  of  our 
comprehensive income include the after tax effect of changes in the net unrealized gain/loss on securities available 
for  sale,  changes  in  the  net  unrealized  gain  on  securities  transferred  to  held  to  maturity  and  changes  in  the  net 
actuarial  gain/loss  on  defined  benefit  post-retirement  benefit  plans.  See  Note  14  -  Other  Comprehensive  Income 
(Loss).

Derivative Financial Instruments. Our hedging policies permit the use of various derivative financial instruments 
to manage interest rate risk or to hedge specified assets and liabilities. All derivatives are recorded at fair value on 
our  balance  sheet.  Derivatives  executed  with  the  same  counterparty  are  generally  subject  to  master  netting 
arrangements,  however,  fair  value  amounts  recognized  for  derivatives  and  fair  value  amounts  recognized  for  the 
right/obligation to reclaim/return cash collateral are not offset for financial reporting purposes. We may be required 
to  recognize  certain  contracts  and  commitments  as  derivatives  when  the  characteristics  of  those  contracts  and 
commitments meet the definition of a derivative.

To  qualify  for  hedge  accounting,  derivatives  must  be  highly  effective  at  reducing  the  risk  associated  with  the 
exposure being hedged and must be designated as a hedge at the inception of the derivative contract. We consider a 
hedge to be highly effective if the change in fair value of the derivative hedging instrument is within 80% to 125% 
of the opposite change in the fair value of the hedged item attributable to the hedged risk. If derivative instruments 
are designated as hedges of fair values, and such hedges are highly effective, both the change in the fair value of the 
hedge and the hedged item are included in current earnings. Fair value adjustments related to cash flow hedges are 
recorded in other comprehensive income and are reclassified to earnings when the hedged transaction is reflected in 
earnings. Ineffective portions of hedges are reflected in earnings as they occur. Actual cash receipts and/or payments 
and related accruals on derivatives related to hedges are recorded as adjustments to the interest income or interest 
expense  associated  with  the  hedged  item.  During  the  life  of  the  hedge,  we  formally  assess  whether  derivatives 
designated  as  hedging  instruments  continue  to  be  highly  effective  in  offsetting  changes  in  the  fair  value  or  cash 
flows of hedged items. If it is determined that a hedge has ceased to be highly effective, we will discontinue hedge 
accounting prospectively. At such time, previous adjustments to the carrying value of the hedged item are reversed 
into current earnings and the derivative instrument is reclassified to a trading position recorded at fair value.

Fair Value Measurements. In general, fair values of financial instruments are based upon quoted market prices, 
where available. If such quoted market prices are not available, fair value is based upon internally developed models 
that  primarily  use,  as  inputs,  observable  market-based  parameters.  Valuation  adjustments  may  be  made  to  ensure 
that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty 
credit quality and our creditworthiness, among other things, as well as unobservable parameters. Any such valuation 
adjustments are applied consistently over time. See Note 17 - Fair Value Measurements.

Transfers of Financial Assets. Transfers of financial assets are accounted for as sales when control over the assets 
has  been  surrendered.  Control  over  transferred  assets  is  deemed  to  be  surrendered  when  (i)  the  assets  have  been 
isolated from us, (ii) the transferee obtains the right (free of conditions that constrain it from taking advantage of that 
right) to pledge or exchange the transferred assets, and (iii) we do not maintain effective control over the transferred 
assets through an agreement to repurchase them before their maturity.

Loss  Contingencies.  Loss  contingencies,  including  claims  and  legal  actions  arising  in  the  ordinary  course  of 
business are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be 
reasonably estimated.

Trust  Assets.  Assets  of  our  trust  department,  other  than  cash  on  deposit  at  Frost  Bank,  are  not  included  in  the 

accompanying financial statements because they are not our assets.

Accounting Changes, Reclassifications and Restatements. Certain items in prior financial statements have been 

reclassified to conform to the current presentation. 

As discussed above, on January 1, 2020 we adopted the provisions of ASC 326 using the modified retrospective 
method for all financial assets measured at amortized cost and off-balance-sheet credit exposures. Upon adoption, 
we recognized an after-tax cumulative effect reduction to retained earnings totaling $29.3 million, as detailed in the 
table  below.  Operating  results  for  periods  after  January  1,  2020  are  presented  in  accordance  with  ASC  326  while 
prior period amounts continue to be reported in accordance with previously applicable standards and the accounting 
policies as described above.

The  following  table  details  the  impact  of  the  adoption  of  ASC  326  on  the  allowance  for  credit  losses  as  of 

January 1, 2020.

On January 1, 2019, we adopted certain accounting standard updates related to accounting for leases, primarily 
ASU 2016-02 “Leases (Topic 842)” and subsequent updates. Among other things, these updates require lessees to 
recognize a lease liability, measured on a discounted basis, related to the lessee's obligation to make lease payments 
arising  under  a  lease  contract;  and  a  right-of-use  asset  related  to  the  lessee’s  right  to  use,  or  control  the  use  of,  a 
specified asset for the lease term. The updates did not significantly change lease accounting requirements applicable 
to  lessors  and  did  not  significantly  impact  our  financial  statements  in  relation  to  contracts  whereby  we  act  as  a 
lessor. We adopted the updates using a modified-retrospective transition approach and recognized right-of-use lease 
assets and related lease liabilities totaling $170.5 million and $174.4 million, respectively, as of January 1, 2019. We 
elected  to  apply  certain  practical  adoption  expedients  provided  under  the  updates  whereby  we  did  not  reassess 
(i)  whether  any  expired  or  existing  contracts  are  or  contain  leases,  (ii)  the  lease  classification  for  any  expired  or 
existing  leases  and  (iii)  initial  direct  costs  for  any  existing  leases.  We  did  not  elect  to  apply  the  recognition 
requirements of the updates to short-term leases. See Note 4 - Premises and Equipment and Lease Commitments.

On  January  1,  2019,  we  also  adopted  ASU  2017-08  “Receivables  -  Nonrefundable  Fees  and  Other  Costs 
(Subtopic  310-20)  -  Premium  Amortization  on  Purchased  Callable  Debt  Securities.”  ASU  2017-08  shortens  the 
amortization period for certain callable debt securities held at a premium to require such premiums to be amortized 
to  the  earliest  call  date  unless  applicable  guidance  related  to  certain  pools  of  securities  is  applied  to  consider 
estimated prepayments. Under prior guidance, entities were generally required to amortize premiums on individual, 
non-pooled callable debt securities as a yield adjustment over the contractual life of the security. ASU 2017-08 does 
not  change  the  accounting  for  callable  debt  securities  held  at  a  discount.  Upon  adoption,  using  a  modified 
retrospective transition adoption approach, we recognized a cumulative effect reduction to retained earnings totaling 
$14.7 million.

All  mortgage-backed  securities  included  in  the  above  table  were  issued  by  U.S.  government  agencies  and 
corporations.  The  carrying  value  of  held-to-maturity  securities  pledged  to  secure  public  funds,  trust  deposits, 
repurchase  agreements  and  for  other  purposes,  as  required  or  permitted  by  law  was  $642.3  million  and  $659.2 
million  at  December  31,  2021  and  2020,  respectively.  Accrued  interest  receivable  on  held-to-maturity  securities 
totaled  $18.4  million  and  $21.7  million  at  December  31,  2021  and  2020,  respectively  and  is  included  in  accrued 
interest receivable and other assets in the accompanying consolidated balance sheets. 

From time to time, we have reclassified certain securities from available for sale to held to maturity. During 2019, 
we reclassified securities with an aggregate fair value of $377.8 million and an aggregate net unrealized gain of $3.3 
million  ($2.6  million,  net  of  tax)  on  the  date  of  the  transfer.  The  net  unamortized,  unrealized  gain  remaining  on 
transferred  securities,  including  those  transferred  in  2019  and  in  years  prior,  included  in  accumulated  other 
comprehensive  income  in  the  accompanying  balance  sheet  totaled  $2.5  million  ($2.0  million,  net  of  tax)  at 
December 31, 2021 and $3.5 million ($2.8 million, net of tax) at December 31, 2020. This amount will be amortized 
out  of  accumulated  other  comprehensive  income  over  the  remaining  life  of  the  underlying  securities  as  an 
adjustment of the yield on those securities.

The allowance for credit losses on held-to-maturity securities is a contra-asset valuation account that is deducted 
from  the  amortized  cost  basis  of  held-to-maturity  securities  to  present  the  net  amount  expected  to  be  collected. 
Management measures expected credit losses on held-to-maturity securities on a collective basis by major security 
type  with  each  type  sharing  similar  risk  characteristics,  and  considers  historical  credit  loss  information  that  is 
adjusted  for  current  conditions  and  reasonable  and  supportable  forecasts.  With  regard  to  U.S.  Treasury  and 
residential  mortgage-backed  securities  issued  by  the  U.S.  government,  or  agencies  thereof,  it  is  expected  that  the 
securities will not be settled at prices less than the amortized cost bases of the securities as such securities are backed 
by the full faith and credit of and/or guaranteed by the U.S. government. Accordingly, no allowance for credit losses 
has been recorded for these securities. With regard to securities issued by States and political subdivisions and other 
held-to-maturity  securities,  management  considers  (i)  issuer  bond  ratings,  (ii)  historical  loss  rates  for  given  bond 

89

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
ratings, (iii) whether issuers continue to make timely principal and interest payments under the contractual terms of 
the securities, (iv) internal forecasts and (v) whether or not such securities are guaranteed by the Texas Permanent 
School Fund (“PSF”) or pre-refunded by the issuers.

The  following  table  summarizes  Moody's  and/or  Standard  &  Poor's  bond  ratings  for  our  portfolio  of  held-to-

maturity securities issued by States and political subdivisions and other securities as of December 31, 2021:

Historical loss rates associated with securities having similar grades as those in our portfolio have generally not 
been  significant.  Furthermore,  as  of  December  31,  2021,  there  were  no  past  due  principal  or  interest  payments 
associated with these securities. The PSF is a sovereign wealth fund which serves to provide revenues for funding of 
public  primary  and  secondary  education  in  the  State  of  Texas.  Based  upon  (i)  the  PSF's  AAA  insurer  financial 
strength rating, (ii) the PSF's substantial capitalization and excess guarantee capacity and (iii) a zero historical loss 
rate,  no  allowance  for  credit  losses  has  been  recorded  for  securities  guaranteed  by  the  PSF  as  there  is  no  current 
expectation of credit losses related to these securities. Pre-refunded securities have been defeased by the issuer and 
are fully secured by cash and/or U.S. Treasury securities held in escrow for payment to holders when the underlying 
call dates of the securities are reached. Accordingly, no allowance for credit losses has been recorded for securities 
that have been defeased as there is no current expectation of credit losses related to these securities.

All  mortgage-backed  securities  included  in  the  above  table  were  issued  by  U.S.  government  agencies  and 
corporations.  At  December  31,  2021  all  of  the  securities  in  our  available  for  sale  municipal  bond  portfolio  were 
issued by the State of Texas or political subdivisions or agencies within the State of Texas, of which approximately 
76.6%  are  either  guaranteed  by  the  PSF  or  have  been  pre-refunded.  Securities  with  limited  marketability,  such  as 
stock in the Federal Reserve Bank and the Federal Home Loan Bank, are carried at cost and are reported as other 
available for sale securities in the table above. The carrying value of available-for-sale securities pledged to secure 
public funds, trust deposits, repurchase agreements and for other purposes, as required or permitted by law was $5.8 
billion and $4.4 billion at December 31, 2021 and 2020, respectively. Accrued interest receivable on available-for-
sale  securities  totaled  $120.5  million  and  $111.0  million  at  December  31,  2021  and  2020,  respectively,  and  is 
included in accrued interest receivable and other assets in the accompanying consolidated balance sheets.

The table below summarizes, as of December 31, 2021, securities available for sale in an unrealized loss position 
for which an allowance for credit losses has not been recorded, aggregated by type of security and length of time in a

As of December 31, 2021, no allowance for credit losses has been recognized on available for sale securities in an 
unrealized loss position as management does not believe any of the securities are impaired due to reasons of credit 
quality.  This  is  based  upon  our  analysis  of  the  underlying  risk  characteristics,  including  credit  ratings,  and  other 
qualitative  factors  related  to  our  available  for  sale  securities  and  in  consideration  of  our  historical  credit  loss 
experience  and  internal  forecasts.  The  issuers  of  these  securities  continue  to  make  timely  principal  and  interest 
payments under the contractual terms of the securities. Furthermore, management does not have the intent to sell any 
of the securities classified as available for sale in the table above and believes that it is more likely than not that we 
will  not  have  to  sell  any  such  securities  before  a  recovery  of  cost.  The  unrealized  losses  are  due  to  increases  in 
market interest rates over the yields available at the time the underlying securities were purchased. The fair value is 
expected  to  recover  as  the  securities  approach  their  maturity  date  or  repricing  date  or  if  market  yields  for  such 
investments decline.

Contractual Maturities. The following table summarizes the maturity distribution schedule of securities held to 
maturity  and  securities  available  for  sale  as  of  December  31,  2021.  Mortgage-backed  securities  are  included  in 
maturity categories based on their stated maturity date. Expected maturities may differ from contractual maturities 
because  issuers  may  have  the  right  to  call  or  prepay  obligations.  Other  securities  classified  as  available  for  sale 
include stock in the Federal Reserve Bank and the Federal Home Loan Bank, which have no maturity date. These 
securities have been included in the total column only.

Concentrations of Credit. Most of our lending activity occurs within the State of Texas, including the four largest 
metropolitan areas of Austin, Dallas/Ft. Worth, Houston and San Antonio, as well as other markets. The majority of 
our loan portfolio consists of commercial and industrial and commercial real estate loans. As of December 31, 2021 
and 2020, there were no concentrations of loans related to any single industry in excess of 10% of total loans. At 
such dates, the largest industry concentration was related to the energy industry, which totaled 6.6% of total loans, or 
6.8%  excluding  PPP  Loans  at  December  31,  2021  and  7.1%  of  total  loans,  or  8.2%  excluding  PPP  Loans  at 
December 31, 2020. Unfunded commitments to extend credit and standby letters of credit issued to customers in the 
energy industry totaled $891.4 million and $68.9 million, respectively, as of December 31, 2021.

Foreign  Loans.  We  have  U.S.  dollar  denominated  loans  and  commitments  to  borrowers  in  Mexico.  The 
outstanding  balance  of  these  loans  and  the  unfunded  amounts  available  under  these  commitments  were  not 
significant at December 31, 2021 or 2020.

Overdrafts. Deposit account overdrafts reported as loans totaled $7.8 million and $5.6 million at December 31, 

2021 and 2020.

Accrued  Interest  Receivable.  Accrued  interest  receivable  on  loans  totaled  $40.0  million  and  $48.7  million  at 
December  31,  2021  and  2020,  respectively  and  is  included  in  accrued  interest  receivable  and  other  assets  in  the 
accompany consolidated balance sheets.

Non-Accrual and Past Due Loans. Loans are considered past due if the required principal and interest payments 
have  not  been  received  as  of  the  date  such  payments  were  due.  Loans  are  placed  on  non-accrual  status  when,  in 
management’s  opinion,  the  borrower  may  be  unable  to  meet  payment  obligations  as  they  become  due,  as  well  as 
when required by regulatory provisions. In determining whether or not a borrower may be unable to meet payment 
obligations for each class of loans, we consider the borrower’s debt service capacity through the analysis of current 
financial  information,  if  available,  and/or  current  information  with  regards  to  our  collateral  position.  Regulatory 
provisions would typically require the placement of a loan on non-accrual status if (i) principal or interest has been 
in default for a period of 90 days or more unless the loan is both well secured and in the process of collection or 
(ii) full payment of principal and interest is not expected. Loans may be placed on non-accrual status regardless of 
whether or not such loans are considered past due. When interest accrual is discontinued, all unpaid accrued interest 
is reversed. Interest income on non-accrual loans is recognized only to the extent that cash payments are received in 
excess  of  principal  due.  A  loan  may  be  returned  to  accrual  status  when  all  the  principal  and  interest  amounts 
contractually  due  are  brought  current  and  future  principal  and  interest  amounts  contractually  due  are  reasonably 
assured, which is typically evidenced by a sustained period (at least six months) of repayment performance by the 
borrower.

Year-end non-accrual loans, segregated by class of loans, were as follows:

In  the  tables  above,  loans  reported  as  2021  originations  as  of  December  31,  2021  and  loans  reported  as  2020 
originations  as  of  December  31,  2020  were,  for  the  most  part,  first  originated  in  various  years  prior  to  2021  and 
2020, respectively, but were renewed in the respective year. Had non-accrual loans performed in accordance with 
their original contract terms, we would have recognized additional interest income, net of tax, of approximately $1.8 
million in 2021, $2.9 million in 2020 and $3.9 million in 2019.

Troubled  Debt  Restructurings.  The  restructuring  of  a  loan  is  considered  a  “troubled  debt  restructuring”  if  both 
(i) the borrower is experiencing financial difficulties and (ii) the creditor has granted a concession. Concessions may 
include  interest  rate  reductions  or  below  market  interest  rates,  principal  forgiveness,  restructuring  amortization 
schedules,  reductions  in  collateral  and  other  actions  intended  to  minimize  potential  losses.  Troubled  debt 
restructurings that occurred during 2021, 2020 and 2019 are set forth in the following table.

Loan modifications are typically related to extending amortization periods, converting loans to interest only for a 
limited  period  of  time,  deferral  of  interest  payments,  waiver  of  certain  covenants,  consolidating  notes  and/or 
reducing collateral or interest rates. The modifications during the reported periods did not significantly impact our 
determination of the allowance for credit losses on loans.

Credit  Quality  Indicators.  As  part  of  the  on-going  monitoring  of  the  credit  quality  of  our  loan  portfolio, 
management tracks certain credit quality indicators including trends related to (i) the weighted-average risk grade of 
commercial  loans,  (ii)  the  level  of  classified  commercial  loans,  (iii)  the  delinquency  status  of  consumer  loans 
(iv) non-performing loans (see details above) and (vi) the general economic conditions in the State of Texas.

We utilize a risk grading matrix to assign a risk grade to each of our commercial loans. Loans are graded on a 

scale of 1 to 14. A description of the general characteristics of the 14 risk grades is as follows:

•

•

•

•

•

•

•

•

•

Grades 1, 2 and 3 - These grades include loans to very high credit quality borrowers of investment or near 
investment  grade.  These  borrowers  are  generally  publicly  traded  (grades  1  and  2),  have  significant  capital 
strength, moderate leverage, stable earnings and growth, and readily available financing alternatives. Smaller 
entities, regardless of strength, would generally not fit in these grades.

Grades  4  and  5  -  These  grades  include  loans  to  borrowers  of  solid  credit  quality  with  moderate  risk. 
Borrowers in these grades are differentiated from higher grades on the basis of size (capital and/or revenue), 
leverage, asset quality and the stability of the industry or market area.

Grades 6, 7 and 8 - These grades include “pass grade” loans to borrowers of acceptable credit quality and 
risk. Such borrowers are differentiated from Grades 4 and 5 in terms of size, secondary sources of repayment 
or they are of lesser stature in other key credit metrics in that they may be over-leveraged, under capitalized, 
inconsistent in performance or in an industry or an economic area that is known to have a higher level of 
risk, volatility, or susceptibility to weaknesses in the economy.

Grade  9  -  This  grade  includes  loans  on  management’s  “watch  list”  and  is  intended  to  be  utilized  on  a 
temporary basis for pass grade borrowers where a significant risk-modifying action is anticipated in the near 
term.

Grade 10 - This grade is for “Other Assets Especially Mentioned” in accordance with regulatory guidelines. 
This  grade  is  intended  to  be  temporary  and  includes  loans  to  borrowers  whose  credit  quality  has  clearly 
deteriorated and are at risk of further decline unless active measures are taken to correct the situation.

Grade 11 - This grade includes “Substandard” loans, in accordance with regulatory guidelines, for which the 
accrual of interest has not been stopped. By definition under regulatory guidelines, a “Substandard” loan has 
defined weaknesses which make payment default or principal exposure likely, but not yet certain. Such loans 
are apt to be dependent upon collateral liquidation, a secondary source of repayment or an event outside of 
the normal course of business.

Grade 12 - This grade includes “Substandard” loans, in accordance with regulatory guidelines, for which the 
accrual of interest has been stopped. This grade includes loans where interest is more than 120 days past due 
and not fully secured and loans where a specific valuation allowance may be necessary, but generally does 
not exceed 30% of the principal balance.

Grade 13 - This grade includes “Doubtful” loans in accordance with regulatory guidelines. Such loans are 
placed  on  non-accrual  status  and  may  be  dependent  upon  collateral  having  a  value  that  is  difficult  to 
determine  or  upon  some  near-term  event  which  lacks  certainty.  Additionally,  these  loans  generally  have  a 
specific valuation allowance in excess of 30% of the principal balance.

Grade 14 - This grade includes “Loss” loans in accordance with regulatory guidelines. Such loans are to be 
charged-off or charged-down when payment is acknowledged to be uncertain or when the timing or value of 
payments cannot be determined. “Loss” is not intended to imply that the loan or some portion of it will never 
be paid, nor does it in any way imply that there has been a forgiveness of debt.

In  monitoring  credit  quality  trends  in  the  context  of  assessing  the  appropriate  level  of  the  allowance  for  credit 
losses on loans, we monitor portfolio credit quality by the weighted-average risk grade of each class of commercial 
loan.  Individual  relationship  managers,  under  the  oversight  of  credit  administration,  review  updated  financial 
information for all pass grade loans to reassess the risk grade on at least an annual basis. When a loan has a risk 
grade  of  9,  it  is  still  considered  a  pass  grade  loan;  however,  it  is  considered  to  be  on  management’s  “watch  list,” 
where  a  significant  risk-modifying  action  is  anticipated  in  the  near  term.  When  a  loan  has  a  risk  grade  of  10  or 
higher, a special assets officer monitors the loan on an on-going basis.

The  following  tables  present  weighted-average  risk  grades  for  all  commercial  loans,  by  class  and  year  of 
origination/renewal as of December 31, 2021 and 2020. Paycheck Protection Program (“PPP”) loans are excluded as 
such loans are fully guaranteed by the Small Business Administration (“SBA”).

At December 31, 2021 and 2020, the weighted-average risk grades for “pass grade” (risk grades 1-8) loans were 
6.01 and 6.13, respectively, for commercial and industrial; 5.78 and 5.99, respectively, for energy; 6.91 and 6.97, 
respectively, for commercial real estate - buildings, land and other; and 6.99 and 6.99, respectively,  for commercial 
real  estate  -  construction.  Furthermore,  in  the  tables  above,  there  are  loans  reported  as  2021  originations  as  of 
December  31,  2021  and  2020  originations  as  of  December  31,  2020  that  have  risk  grades  of  11  or  higher.  These

In assessing the general economic conditions in the State of Texas, management monitors and tracks the Texas 
Leading  Index  (“TLI”),  which  is  produced  by  the  Federal  Reserve  Bank  of  Dallas.  The  TLI  is  a  single  summary 
statistic that is designed to signal the likelihood of the Texas economy’s transition from expansion to recession and 
vice versa. Management believes this index provides a reliable indication of the direction of overall credit quality. 
The TLI is a composite of the following eight leading indicators: (i) Texas Value of the Dollar, (ii) U.S. Leading

Index, (iii) real oil prices (iv) well permits, (v) initial claims for unemployment insurance, (vi) Texas Stock Index, 
(vii)  Help-Wanted  Index  and  (viii)  average  weekly  hours  worked  in  manufacturing.  The  TLI  totaled  134.7  at 
December  31,  2021  and  118.1  at  December  31,  2020.  A  higher  TLI  value  implies  more  favorable  economic 
conditions.

Allowance  For  Credit  Losses  -  Loans.  The  allowance  for  credit  losses  on  loans  is  a  contra-asset  valuation 
account, calculated in accordance with ASC 326, that is deducted from the amortized cost basis of loans to present 
the  net  amount  expected  to  be  collected.  The  amount  of  the  allowance  represents  management's  best  estimate  of 
current  expected  credit  losses  on  loans  considering  available  information,  from  internal  and  external  sources, 
relevant  to  assessing  collectibility  over  the  loans'  contractual  terms,  adjusted  for  expected  prepayments  when 
appropriate. The contractual term excludes expected extensions, renewals and modifications unless (i) management 
has  a  reasonable  expectation  that  a  trouble  debt  restructuring  will  be  executed  with  an  individual  borrower  or 
(ii) such extension or renewal options are not unconditionally cancellable by us and, in such cases, the borrower is 
likely  to  meet  applicable  conditions  and  likely  to  request  extension  or  renewal.  Relevant  available  information 
includes  historical  credit  loss  experience,  current  conditions  and  reasonable  and  supportable  forecasts.  While 
historical  credit  loss  experience  provides  the  basis  for  the  estimation  of  expected  credit  losses,  adjustments  to 
historical  loss  information  may  be  made  for  differences  in  current  portfolio-specific  risk  characteristics, 
environmental conditions or other relevant factors. The allowance for credit losses is measured on a collective basis 
for  portfolios  of  loans  when  similar  risk  characteristics  exist.  Loans  that  do  not  share  risk  characteristics  are 
evaluated  for  expected  credit  losses  on  an  individual  basis  and  excluded  from  the  collective  evaluation.  Expected 
credit losses for collateral dependent loans, including loans where the borrower is experiencing financial difficulty 
but foreclosure is not probable, are based on the fair value of the collateral at the reporting date, adjusted for selling 
costs as appropriate. 

Credit  loss  expense  related  to  loans  reflects  the  totality  of  actions  taken  on  all  loans  for  a  particular  period 
including  any  necessary  increases  or  decreases  in  the  allowance  related  to  changes  in  credit  loss  expectations 
associated  with  specific  loans  or  pools  of  loans.  Portions  of  the  allowance  may  be  allocated  for  specific  credits; 
however,  the  entire  allowance  is  available  for  any  credit  that,  in  management’s  judgment,  should  be  charged  off. 
While  management  utilizes  its  best  judgment  and  information  available,  the  ultimate  appropriateness  of  the 
allowance  is  dependent  upon  a  variety  of  factors  beyond  our  control,  including  the  performance  of  our  loan 
portfolio,  the  economy,  changes  in  interest  rates  and  the  view  of  the  regulatory  authorities  toward  loan 
classifications.

In  calculating  the  allowance  for  credit  losses,  most  loans  are  segmented  into  pools  based  upon  similar 
characteristics  and  risk  profiles.  Common  characteristics  and  risk  profiles  include  the  type/purpose  of  loan, 
underlying  collateral,  geographical  similarity  and  historical/expected  credit  loss  patterns.  In  developing  these  loan 
pools for the purposes of modeling expected credit losses, we also analyzed the degree of correlation in how loans 
within  each  portfolio  respond  when  subjected  to  varying  economic  conditions  and  scenarios  as  well  as  other 
portfolio  stress  factors.  For  modeling  purposes,  our  loan  pools  include  (i)  commercial  and  industrial  and  energy  - 
non-revolving, (ii) commercial and industrial and energy - revolving, (iii) commercial real estate - owner occupied, 
(iv)  commercial  real  estate  -  non-owner  occupied,  (v)  commercial  real  estate  -  construction/land  development, 
(vi) consumer real estate and (vii) consumer and other. We periodically reassess each pool to ensure the loans within 
the pool continue to share similar characteristics and risk profiles and to determine whether further segmentation is 
necessary.

For each loan pool, we measure expected credit losses over the life of each loan utilizing a combination of models 
which  measure  (i)  probability  of  default  (“PD”),  which  is  the  likelihood  that  loan  will  stop  performing/default, 
(ii) probability of attrition (“PA”), which is the likelihood that a loan will pay-off prior to maturity, (iii) loss given 
default (“LGD”), which is the expected loss rate for loans in default and (iv) exposure at default (“EAD”), which is 
the estimated outstanding principal balance of the loans upon default, including the expected funding of unfunded 
commitments outstanding as of the measurement date. For certain commercial loan portfolios, the PD is calculated 
using a transition matrix to determine the likelihood of a customer’s risk grade migrating from one specified range 
of risk grades to a different specified range. Expected credit losses are calculated as the product of PD (adjusted for 
attrition),  LGD  and  EAD.  This  methodology  builds  on  default  probabilities  already  incorporated  into  our  risk 
grading process by utilizing pool-specific historical loss rates to calculate expected credit losses. These pool-specific 
historical loss rates may be adjusted for current macroeconomic assumptions, as further discussed below, and other 
factors such as differences in underwriting standards, portfolio mix, or when historical asset terms do not reflect the 
contractual terms of the financial assets being evaluated as of the measurement date. Each time we measure expected 

101

credit  losses,  we  assess  the  relevancy  of  historical  loss  information  and  consider  any  necessary  adjustments  to 
address  any  differences  in  asset-specific  characteristics.  Due  to  their  short-term  nature,  expected  credit  losses  for 
overdrafts included in consumer and other loans are based solely upon a weighting of recent historical charge-offs 
over a period of three years.

The measurement of expected credit losses is impacted by loan/borrower attributes and certain macroeconomic 
variables.  Significant  loan/borrower  attributes  utilized  in  our  modeling  processes  include,  among  other  things, 
(i)  origination  date,  (ii)  maturity  date,  (iii)  payment  type,  (iv)  collateral  type  and  amount,  (v)  current  risk  grade, 
(vi)  current  unpaid  balance  and  commitment  utilization  rate,  (vii)  payment  status/delinquency  history  and 
(viii)  expected  recoveries  of  previously  charged-off  amounts.  Significant  macroeconomic  variables  utilized  in  our 
modeling  processes  include,  among  other  things,  (i)  Gross  State  Product  for  Texas  and  U.S.  Gross  Domestic 
Product,  (ii)  selected  market  interest  rates  including  U.S.  Treasury  rates,  bank  prime  rate,  30-year  fixed  mortgage 
rate,  BBB  corporate  bond  rate,  among  others,  (iii)  unemployment  rates,  (iv)  commercial  and  residential  property 
prices  in  Texas  and  the  U.S.  as  a  whole,  (v)  West  Texas  Intermediate  crude  oil  price  and  (vi)  total  stock  market 
index. 

PD  and  PA  were  estimated  by  analyzing  internally-sourced  data  related  to  historical  performance  of  each  loan 
pool  over  a  complete  economic  cycle.  PD  and  PA  are  adjusted  to  reflect  the  current  impact  of  certain 
macroeconomic variables as well as their expected changes over a reasonable and supportable forecast period. We 
have  determined  that  we  are  reasonably  able  to  forecast  the  macroeconomic  variables  used  in  our  modeling 
processes with an acceptable degree of confidence for a total of two years with the last twelve months of the forecast 
period  encompassing  a  reversion  process  whereby  the  forecasted  macroeconomic  variables  are  reverted  to  their 
historical  mean  utilizing  a  rational,  systematic  basis.  The  macroeconomic  variables  utilized  as  inputs  in  our 
modeling  processes  were  subjected  to  a  variety  of  analysis  procedures  and  were  selected  primarily  based  on 
statistical  relevancy  and  correlation  to  our  historical  credit  losses.  By  reverting  these  modeling  inputs  to  their 
historical mean and considering loan/borrower specific attributes, our models are intended to yield a measurement of 
expected  credit  losses  that  reflects  our  average  historical  loss  rates  for  periods  subsequent  to  the  twelve-month 
reversion period. The LGD is based on historical recovery averages for each loan pool, adjusted to reflect the current 
impact of certain macroeconomic variables as well as their expected changes over a two-year forecast period, with 
the final twelve months of the forecast period encompassing a reversion process, which management considers to be 
both reasonable and supportable. This same forecast/reversion period is used for all macroeconomic variables used 
in all of our models. EAD is estimated using a linear regression model that estimates the average percentage of the 
loan balance that remains at the time of a default event.

Management  qualitatively  adjusts  model  results  for  risk  factors  that  are  not  considered  within  our  modeling 
processes but are nonetheless relevant in assessing the expected credit losses within our loan pools. These qualitative 
factor (“Q-Factor”) and other qualitative adjustments may increase or decrease management's estimate of expected 
credit losses by a calculated percentage or amount based upon the estimated level of risk. The various risks that may 
be  considered  in  making  Q-Factor  and  other  qualitative  adjustments  include,  among  other  things,  the  impact  of 
(i)  changes  in  lending  policies  and  procedures,  including  changes  in  underwriting  standards  and  practices  for 
collections, write-offs, and recoveries, (ii) actual and expected changes in international, national, regional, and local 
economic and business conditions and developments that affect the collectibility of the loan pools, (iii) changes in 
the  nature  and  volume  of  the  loan  pools  and  in  the  terms  of  the  underlying  loans,  (iv)  changes  in  the  experience, 
ability,  and  depth  of  our  lending  management  and  staff,  (v)  changes  in  volume  and  severity  of  past  due  financial 
assets,  the  volume  of  non-accrual  assets,  and  the  volume  and  severity  of  adversely  classified  or  graded  assets, 
(vi) changes in the quality of our credit review function, (vii) changes in the value of the underlying collateral for 
loans that are non-collateral dependent, (viii) the existence, growth, and effect of any concentrations of credit and 
(ix)  other  factors  such  as  the  regulatory,  legal  and  technological  environments;  competition;  and  events  such  as 
natural disasters or health pandemics.

In  some  cases,  management  may  determine  that  an  individual  loan  exhibits  unique  risk  characteristics  which 
differentiate  the  loan  from  other  loans  within  our  loan  pools.  In  such  cases,  the  loans  are  evaluated  for  expected 
credit  losses  on  an  individual  basis  and  excluded  from  the  collective  evaluation.  Specific  allocations  of  the 
allowance  for  credit  losses  are  determined  by  analyzing  the  borrower’s  ability  to  repay  amounts  owed,  collateral 
deficiencies, the relative risk grade of the loan and economic conditions affecting the borrower’s industry, among 
other  things.  A  loan  is  considered  to  be  collateral  dependent  when,  based  upon  management's  assessment,  the 
borrower  is  experiencing  financial  difficulty  and  repayment  is  expected  to  be  provided  substantially  through  the 
operation or sale of the collateral. In such cases, expected credit losses are based on the fair value of the collateral at 

102

the  measurement  date,  adjusted  for  estimated  selling  costs  if  satisfaction  of  the  loan  depends  on  the  sale  of  the 
collateral. We reevaluate the fair value of collateral supporting collateral dependent loans on a quarterly basis. The 
fair value of real estate collateral supporting collateral dependent loans is evaluated by our internal appraisal services 
using a methodology that is consistent with the Uniform Standards of Professional Appraisal Practice. The fair value 
of collateral supporting collateral dependent construction loans is based on an “as is” valuation.

The  following  table  presents  details  of  the  allowance  for  credit  losses  on  loans  segregated  by  loan  portfolio 
segment as of December 31, 2021 and 2020, calculated in accordance with the CECL methodology described above. 
No allowance for credit losses has been recognized for PPP loans as such loans are fully guaranteed by the SBA.

Generally, a commercial loan, or a portion thereof, is charged-off immediately when it is determined, through the 
analysis of any available current financial information with regards to the borrower, that the borrower is incapable of 
servicing  unsecured  debt,  there  is  little  or  no  prospect  for  near  term  improvement  and  no  realistic  strengthening 
action of significance is pending or, in the case of secured debt, when it is determined, through analysis of current 
information  with  regards  to  our  collateral  position,  that  amounts  due  from  the  borrower  are  in  excess  of  the 
calculated  current  fair  value  of  the  collateral.  Notwithstanding  the  foregoing,  generally,  commercial  loans  that 
become past due 180 cumulative days are charged-off. Generally, a consumer loan, or a portion thereof, is charged-
off in accordance with regulatory guidelines which provide that such loans be charged-off when we become aware 
of  the  loss,  such  as  from  a  triggering  event  that  may  include  new  information  about  a  borrower’s  intent/ability  to 
repay the loan, bankruptcy, fraud or death, among other things, but in any event the charge-off must be taken within 
specified delinquency time frames. Such delinquency time frames state that closed-end retail loans (loans with pre-
defined  maturity  dates,  such  as  real  estate  mortgages,  home  equity  loans  and  consumer  installment  loans)  that 
become past due 120 cumulative days and open-end retail loans (loans that roll-over at the end of each term, such as 
home equity lines of credit) that become past due 180 cumulative days should be classified as a loss and charged-off.

Lease Commitments. We lease certain office facilities and office equipment under operating leases. Rent expense 
for all operating leases totaled $45.6 million in 2021, $46.0 million in 2020 and $42.1 million in 2019. On January 1, 
2019,  we  adopted  a  new  accounting  standard  which  required  the  recognition  of  certain  operating  leases  on  our 
balance  sheet  as  lease  right-of-use  assets  (reported  as  component  of  premises  and  equipment)  and  related  lease 
liabilities  (reported  as  a  component  of  accrued  interest  payable  and  other  liabilities).  See  Note  1  -  Summary  of

Right-of-use lease assets totaled $281.4 million and $292.1 million at December 31, 2021 and 2020, respectively, 
and are reported as a component of premises and equipment on our accompanying consolidated balance sheets. The 
related lease liabilities totaled $313.4 million and $323.0 million at December 31, 2021 and 2020, respectively, and 
are  reported  as  a  component  of  accrued  interest  payable  and  other  liabilities  in  the  accompanying  consolidated 
balance sheets. Lease payments under operating leases that were applied to our operating lease liability totaled $32.1 
million  during  2021  and  $31.6  million  during  2020.  The  following  table  reconciles  future  undiscounted  lease

We lease certain buildings and branch facilities from various entities which are controlled by or affiliated with 
certain  directors.  Payments  related  to  these  leases  totaled  $322  thousand  in  2021,  $9.8  million  in  2020  and  $5.9 
million in 2019. The decrease in these lease payments during 2021 was the result of a director who did not stand for 
re-election and who has a controlling interest in the entity from which we lease our headquarters building. This lease 
originally  commenced  during  the  second  quarter  of  2019  and  we  recognized  a  right-of-use  asset  totaling  $121.7 
million and a related lease liability totaling $121.7 million in connection with this lease. The lease was a separate 
agreement  under  a  comprehensive  development  agreement  between  us,  the  City  of  San  Antonio  and  a  third  party 
controlled by the aforementioned director.

Note 7 - Borrowed Funds

Federal  Funds  Purchased  and  Securities  Sold  Under  Agreements  to  Repurchase.  Federal  funds  purchased  are 
short-term borrowings that typically mature within one to ninety days. Federal funds purchased totaled $25.9 million 
and $48.9 million at December 31, 2021 and 2020. Securities sold under agreements to repurchase are secured short-
term borrowings that typically mature overnight or within thirty to ninety days. Securities sold under agreements to 
repurchase  are  stated  at  the  amount  of  cash  received  in  connection  with  the  transaction.  We  may  be  required  to 
provide additional collateral based on the fair value of the underlying securities. Securities sold under agreements to 
repurchase totaled $2.7 billion and $2.1 billion at December 31, 2021 and 2020.

Subordinated  Notes.  In  March  2017,  we  issued  $100  million  of  4.50%  subordinated  notes  that  mature  on 
March 17, 2027. The notes, which qualify as Tier 2 capital for Cullen/Frost, bear interest at the rate of 4.50% per 
annum, payable semi-annually on each March 17 and September 17. The notes are unsecured and subordinated in 
right of payment to the payment of our existing and future senior indebtedness and structurally subordinated to all 
existing and future indebtedness of our subsidiaries. Unamortized debt issuance costs related to these notes, totaled 
approximately $822 thousand and $1.0 million December 31, 2021 and 2020. Proceeds from sale of the notes were 
used for general corporate purposes.

Junior Subordinated Deferrable Interest Debentures. At December 31, 2021 and 2020, we had $123.7 million of 
junior  subordinated  deferrable  interest  debentures  issued  to  Cullen/Frost  Capital  Trust  II  (“Trust  II”),  a  wholly 
owned Delaware statutory business trust. Unamortized debt issuance costs related to Trust II totaled $701 thousand 
and  $758  thousand  at  December  31,  2021  and  2020.  At  December  31,  2020,  we  also  had  $13.4  million  of  junior 
subordinated  deferrable  interest  debentures  issued  to  WNB  Capital  Trust  I  (“WNB  Trust”),  a  wholly  owned 
Delaware statutory business trust acquired in connection with the acquisition of WNB Bancshares, Inc. (“WNB”) in 
2014. The junior subordinated deferrable interest debentures issued to WNB Trust and the trust preferred securities 
issued by WNB Trust were redeemed in October 2021. Trust II is a variable interest entity for which we are not the 
primary  beneficiary  and,  as  such,  its  accounts  are  not  included  in  our  consolidated  financial  statements.  This  was 
also  the  case  with  WNB  Trust  prior  to  its  dissolution  in  2021.  See  Note  1  -  Summary  of  Significant  Accounting 
Policies for additional information about our consolidation policy. Details of our transactions with the capital trust 
are presented below.

Trust II was formed in 2004 for the purpose of issuing $120.0 million of floating rate (three-month LIBOR plus a 
margin of 1.55%) trust preferred securities, which represent beneficial interests in the assets of the trust. The trust 
preferred  securities  will  mature  on  March  1,  2034  and  are  currently  redeemable  with  the  approval  of  the  Federal 
Reserve Board in whole or in part at our option. Distributions on the trust preferred securities are payable quarterly 
in  arrears  on  March  1,  June  1,  September  1  and  December  1  of  each  year.  Trust  II  also  issued  $3.7  million  of 
common equity securities to Cullen/Frost. The proceeds of the offering of the trust preferred securities and common 
equity securities were used to purchase $123.7 million of floating rate (three-month LIBOR plus a margin of 1.55%, 
which  was  equal  to  1.72%  and  1.78%  at  December  31,  2021  and  2020)  junior  subordinated  deferrable  interest 
debentures issued by us, which have terms substantially similar to the trust preferred securities. 

We have the right at any time during the term of the debentures issued to Trust II to defer payments of interest at 
any time or from time to time for an extension period not exceeding 20 consecutive quarterly periods with respect to 
each extension period. Under the terms of the debentures, in the event that under certain circumstances there is an 
event of default under the debentures or we have elected to defer interest on the debentures, we may not, with certain 
exceptions,  declare  or  pay  any  dividends  or  distributions  on  our  capital  stock  or  purchase  or  acquire  any  of  our 
capital stock.

Payments  of  distributions  on  the  trust  preferred  securities  and  payments  on  redemption  of  the  trust  preferred 
securities  are  guaranteed  by  us  on  a  limited  basis.  We  are  obligated  by  agreement  to  pay  any  costs,  expenses  or 
liabilities  of  Trust  II  other  than  those  arising  under  the  trust  preferred  securities.  Our  obligations  under  the  junior 
subordinated  debentures,  the  related  indenture,  the  trust  agreement  establishing  the  trust,  the  guarantee  and  the 
agreement  as  to  expenses  and  liabilities,  in  the  aggregate,  constitute  a  full  and  unconditional  guarantee  by  us  of 
Trust II’s obligations under the trust preferred securities.

WNB Trust was formed in 2004 by WNB for the purpose of issuing $13.0 million of floating rate trust preferred 
securities, which represented beneficial interests in the assets of the trust. The proceeds of the offering of the trust 
preferred securities along with $403 thousand in proceeds from the issuance of common equity securities were used 

107

to purchase $13.4 million of floating rate (three-month LIBOR plus a margin of 2.35%, which was equal to 2.56% at 
December  31,  2020)  junior  subordinated  deferrable  interest  debentures  issued  by  WNB,  which  had  terms 
substantially  similar  to  the  trust  preferred  securities.  As  noted  above,  the  junior  subordinated  deferrable  interest 
debentures issued to WNB Trust and the trust preferred securities issued by WNB Trust were redeemed in October 
2021.

Although the accounts of Trust II and WNB Trust are not included in our consolidated financial statements, the 
trust preferred securities issued by these are included in the capital of Cullen/Frost for regulatory capital purposes. 
See Note 9 - Capital and Regulatory Matters.

Note 8 - Off-Balance-Sheet Arrangements, Commitments, Guarantees and Contingencies

Financial  Instruments  with  Off-Balance-Sheet  Risk.  In  the  normal  course  of  business,  we  enter  into  various 
transactions,  which,  in  accordance  with  generally  accepted  accounting  principles  in  the  United  States,  are  not 
included  in  our  consolidated  balance  sheets.  We  enter  into  these  transactions  to  meet  the  financing  needs  of  our 
customers. These transactions include commitments to extend credit and standby letters of credit, which involve, to 
varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized in the consolidated 
balance sheets. We minimize our exposure to loss under these commitments by subjecting them to credit approval 
and monitoring procedures. 

We  enter  into  contractual  commitments  to  extend  credit,  normally  with  fixed  expiration  dates  or  termination 
clauses,  at  specified  rates  and  for  specific  purposes.  Substantially  all  of  our  commitments  to  extend  credit  are 
contingent upon customers maintaining specific credit standards at the time of loan funding. Standby letters of credit 
are written conditional commitments issued by us to guarantee the performance of a customer to a third party. In the 
event the customer does not perform in accordance with the terms of the agreement with the third party, we would 
be required to fund the commitment. The maximum potential amount of future payments we could be required to 
make is represented by the contractual amount of the commitment. If the commitment were funded, we would be 
entitled to seek recovery from the customer. Our policies generally require that standby letter of credit arrangements 
contain security and debt covenants similar to those contained in loan agreements.

We consider the fees collected in connection with the issuance of standby letters of credit to be representative of 
the  fair  value  of  our  obligation  undertaken  in  issuing  the  guarantee.  In  accordance  with  applicable  accounting 
standards related to guarantees, we defer fees collected in connection with the issuance of standby letters of credit. 
The fees are then recognized in income proportionately over the life of the standby letter of credit agreement. The 
deferred standby letter of credit fees represent the fair value of our potential obligations under the standby letter of 
credit guarantees. 

Year-end financial instruments with off-balance-sheet risk are presented in the following table. Commitments and 
standby  letters  of  credit  are  presented  at  contractual  amounts;  however,  since  many  of  these  commitments  are 
expected to expire unused or only partially used, the total amounts of these commitments do not necessarily reflect 
future cash requirements.

Allowance  For  Credit  Losses  -  Off-Balance-Sheet  Credit  Exposures.  The  allowance  for  credit  losses  on  off-
balance-sheet credit exposures is a liability account, calculated in accordance with ASC 326, representing expected 
credit  losses  over  the  contractual  period  for  which  we  are  exposed  to  credit  risk  resulting  from  a  contractual 
obligation to extend credit. No allowance is recognized if we have the unconditional right to cancel the obligation. 
Off-balance-sheet  credit  exposures  primarily  consist  of  amounts  available  under  outstanding  lines  of  credit  and 
letters  of  credit  detailed  in  the  table  above.  For  the  period  of  exposure,  the  estimate  of  expected  credit  losses 
considers  both  the  likelihood  that  funding  will  occur  and  the  amount  expected  to  be  funded  over  the  estimated 
remaining  life  of  the  commitment  or  other  off-balance-sheet  exposure.  The  likelihood  and  expected  amount  of 
funding are based on historical utilization rates. The amount of the allowance represents management's best estimate 
of  expected  credit  losses  on  commitments  expected  to  be  funded  over  the  contractual  life  of  the  commitment. 

108

 
 
 
 
Estimating  credit  losses  on  amounts  expected  to  be  funded  uses  the  same  methodology  as  described  for  loans  in 
Note 3 - Loans as if such commitments were funded.

Credit Card Guarantees. We guarantee the credit card debt of certain customers to the merchant bank that issues 
the cards. At December 31, 2021 and 2020, the guarantees totaled approximately $8.6 million and $9.1 million, of 
which amounts, $962 thousand and $8.2 million were fully collateralized.

Trust Accounts. We hold certain assets which are not included in our consolidated balance sheets including assets 
held in fiduciary or custodial capacity on behalf of our trust customers. The estimated fair value of trust assets was 
approximately  $43.3  billion  and  $38.6  billion  at  December  31,  2021  and  2020,  respectively.  These  assets  are 
primarily  composed  of  equity  securities,  fixed  income  securities,  alternative  investments  and  cash  equivalents, 
among other things. 

Executive Change-In-Control Severance Plan. We maintain a change-in-control severance plan for the benefit of 
certain executive officers. Under this plan, each covered person could receive, upon the effectiveness of a change-in-
control, two to three times (depending on the person) their base compensation plus the target bonus established for 
the year, and any unpaid base salary and pro rata target bonus for the year in which the termination occurs, including 
vacation  pay.  Additionally,  the  executive’s  insurance  benefits  will  continue  for  two  to  three  full  years  after  the 
termination and all long-term incentive awards will immediately vest.

Litigation.  We  are  subject  to  various  claims  and  legal  actions  that  have  arisen  in  the  course  of  conducting 
business. Management does not expect the ultimate disposition of these matters to have a material adverse impact on 
our financial statements.

Note 9 - Capital and Regulatory Matters

Banks and bank holding companies are subject to various regulatory capital requirements administered by state 
and  federal  banking  agencies.  Capital  adequacy  guidelines  and,  additionally  for  banks,  prompt  corrective  action 
regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under 
regulatory  accounting  practices.  Capital  amounts  and  classifications  are  also  subject  to  qualitative  judgments  by 
regulators about components, risk weighting and other factors.

Cullen/Frost and Frost Bank are each required to comply with applicable capital adequacy standards established 
by  the  Federal  Reserve  Board  (the  “Basel  III  Capital  Rules”).  Quantitative  measures  established  by  the  Basel  III 
Capital Rules designed to ensure capital adequacy require the maintenance of minimum amounts and ratios (set forth 
below)  of  Common  Equity  Tier  1  capital,  Tier  1  capital  and  Total  capital  (as  defined  in  the  regulations)  to  risk-
weighted assets (as defined), and of Tier 1 capital to adjusted quarterly average assets (as defined).

Cullen/Frost’s  and  Frost  Bank’s  Common  Equity  Tier  1  capital  includes  common  stock  and  related  paid-in 
capital, net of treasury stock, and retained earnings. In connection with the adoption of the Basel III Capital Rules, 
we elected to opt-out of the requirement to include most components of accumulated other comprehensive income in 
Common  Equity  Tier  1.  We  also  elected  to  delay,  for  a  five-year  transitional  period,  the  effects  of  credit  loss 
accounting under CECL from Common Equity Tier 1, as further discussed below. Common Equity Tier 1 for both 
Cullen/Frost  and  Frost  Bank  is  reduced  by  goodwill  and  other  intangible  assets,  net  of  associated  deferred  tax 
liabilities. Frost Bank's Common Equity Tier 1 is also reduced by its equity investment in its financial subsidiary, 
Frost Insurance Agency (“FIA”). 

Tier 1 capital includes Common Equity Tier 1 capital and additional Tier 1 capital. For Cullen/Frost, additional 
Tier  1  capital  at  December  31,  2021  and  2020  included  $145.5  million  of  4.450%  non-cumulative  perpetual 
preferred stock, the details of which is are further discussed below. Frost Bank did not have any additional Tier 1 
capital beyond Common Equity Tier 1 at December 31, 2021 or 2020.

109

 
 
 
 
 
 
Total  capital  includes  Tier  1  capital  and  Tier  2  capital.  Tier  2  capital  for  both  Cullen/Frost  and  Frost  Bank 
includes a permissible portion of the allowance for credit losses on securities, loans and off-balance sheet exposures. 
Tier  2  capital  for  Cullen/Frost  also  includes  trust  preferred  securities  that  were  excluded  from  Tier  1  capital  and 
qualified subordinated debt. At December 31, 2021 and 2020, Cullen/Frost's Tier 2 capital included $120.0 million 
and $133.0 million of trust preferred securities, respectively. The $13.0 million of trust preferred securities issued by 
WNB  Capital  Trust  I  were  redeemed  in  October  2021.  At  both  December  31,  2021  and  2020,  Tier  2  Capital  for 
Cullen/Frost also included $100.0 million related to the permissible portion of our aggregate $100 million of 4.50% 
subordinated notes. The permissible portion of qualified subordinated notes decreases 20% per year during the final 
five years of the term of the notes. 

The  Common  Equity  Tier  1,  Tier  1  and  Total  capital  ratios  are  calculated  by  dividing  the  respective  capital 
amounts by risk-weighted assets. Risk-weighted assets are calculated based on regulatory requirements and include 
total assets, with certain exclusions, allocated by risk weight category, and certain off-balance-sheet items, among 
other  things.  The  leverage  ratio  is  calculated  by  dividing  Tier  1  capital  by  adjusted  quarterly  average  total  assets, 
which exclude goodwill and other intangible assets, among other things.

The  Basel  III  Capital  Rules  require  Cullen/Frost  and  Frost  Bank  to  maintain  (i)  a  minimum  ratio  of  Common 
Equity Tier 1 capital to risk-weighted assets of at least 4.5%, plus a 2.5% “capital conservation buffer” (which is 
added to the 4.5% Common Equity Tier 1 capital ratio, effectively resulting in a minimum ratio of Common Equity 
Tier 1 capital to risk-weighted assets of at least 7.0%), (ii) a minimum ratio of Tier 1 capital to risk-weighted assets 
of  at  least  6.0%,  plus  the  capital  conservation  buffer  (which  is  added  to  the  6.0%  Tier  1  capital  ratio,  effectively 
resulting  in  a  minimum  Tier  1  capital  ratio  of  8.5%),  (iii)  a  minimum  ratio  of  Total  capital  (that  is,  Tier  1  plus 
Tier 2) to risk-weighted assets of at least 8.0%, plus the capital conservation buffer (which is added to the 8.0% total 
capital ratio, effectively resulting in a minimum total capital ratio of 10.5%) and (iv) a minimum leverage ratio of 
4.0%, calculated as the ratio of Tier 1 capital to average quarterly assets.

The capital conservation buffer is designed to absorb losses during periods of economic stress and, as detailed 
above, effectively increases the minimum required risk-weighted capital ratios. Banking institutions with a ratio of 
Common  Equity  Tier  1  capital  to  risk-weighted  assets  below  the  effective  minimum  (4.5%  plus  the  capital 
conservation  buffer  and,  if  applicable,  the  “countercyclical  capital  buffer,”  which  is  discussed  below)  will  face 
constraints  on  dividends,  equity  repurchases  and  compensation  based  on  the  amount  of  the  shortfall  and  the 
institution's “eligible retained income” (that is, four quarter trailing net income, net of distributions and tax effects 
not reflected in net income). The countercyclical capital buffer is applicable to only certain covered institutions and 
does not have any current applicability to Cullen/Frost or Frost Bank. 

As  discussed  in  Note  1  -  Significant  Accounting  Policies,  in  connection  with  the  adoption  of  ASC  326,  we 
recognized an after-tax cumulative effect reduction to retained earnings totaling $29.3 million on January 1, 2020. In 
February 2019, the federal bank regulatory agencies issued a final rule (the “2019 CECL Rule”) that revised certain 
capital  regulations  to  account  for  changes  to  credit  loss  accounting  under  U.S.  GAAP.  The  2019  CECL  Rule 
included  a  transition  option  that  allows  banking  organizations  to  phase  in,  over  a  three-year  period,  the  day-one 
adverse effects of CECL on their regulatory capital ratios (three-year transition option). In March 2020, the federal 
bank  regulatory  agencies  issued  an  interim  final  rule  that  maintains  the  three-year  transition  option  of  the  2019 
CECL Rule and also provides banking organizations that were required under U.S. GAAP (as of January 2020) to 
implement  CECL  before  the  end  of  2020  the  option  to  delay  for  two  years  an  estimate  of  the  effect  of  CECL  on 
regulatory capital, relative to the incurred loss methodology’s effect on regulatory capital, followed by a three-year 
transition  period  (five-year  transition  option).  We  elected  to  adopt  the  five-year  transition  option.  Accordingly,  a 
CECL transitional amount totaling $61.6 million has been added back to CET1 as of December 31, 2021. The CECL 
transitional amount includes $29.3 million related to cumulative effect of adopting CECL and $32.4 million related 
to the estimated incremental effect of CECL since adoption.

In April 2020, we began originating loans to qualified small businesses under the PPP administered by the SBA. 
Federal  bank  regulatory  agencies  have  issued  an  interim  final  rule  that  permits  banks  to  neutralize  the  regulatory 
capital effects of participating in the Paycheck Protection Program Lending Facility (the “PPP Facility”) and clarify 
that PPP loans have a zero percent risk weight under applicable risk-based capital rules. Specifically, a bank may 
exclude  all  PPP  loans  pledged  as  collateral  to  the  PPP  Facility  from  its  average  total  consolidated  assets  for  the 
purposes of calculating its leverage ratio, while PPP loans that are not pledged as collateral to the PPP Facility will 
be included. Our PPP loans are included in the calculation of our leverage ratio as of December 31, 2021 as we did 
not utilize the PPP Facility for funding purposes.

The following table presents actual and required capital ratios as of December 31, 2021 and December 31, 2020 
for  Cullen/Frost  and  Frost  Bank  under  the  Basel  III  Capital  Rules.  Capital  levels  required  to  be  considered  well 
capitalized  are  based  upon  prompt  corrective  action  regulations,  as  amended  to  reflect  the  changes  under  the 
Basel III Capital Rules.

As  of  December  31,  2021,  capital  levels  for  Cullen/Frost  and  Frost  Bank  exceed  all  capital  adequacy 
requirements  under  the  Basel  III  Capital  Rules.  Based  on  the  ratios  presented  above,  capital  levels  as  of 
December 31, 2021 for Cullen/Frost and Frost Bank exceed the minimum levels necessary to be considered “well 
capitalized.”

Cullen/Frost  and  Frost  Bank  are  subject  to  the  regulatory  capital  requirements  administered  by  the  Federal 
Reserve Board and, for Frost Bank, the Federal Deposit Insurance Corporation (“FDIC”). Regulatory authorities can 
initiate  certain  mandatory  actions  if  Cullen/Frost  or  Frost  Bank  fail  to  meet  the  minimum  capital  requirements, 
which  could  have  a  direct  material  effect  on  our  financial  statements.  Management  believes,  as  of  December  31, 
2021, that Cullen/Frost and Frost Bank meet all capital adequacy requirements to which they are subject.

Series  B  Preferred  Stock.  On  November  19,  2020,  we  issued  150,000  shares,  or  $150.0  million  in  aggregate 
liquidation  preference,  of  our  4.450%  Non-Cumulative  Perpetual  Preferred  Stock,  Series  B,  par  value  $0.01  and 
liquidation preference $1,000 per share (“Series B Preferred Stock”). Each share of Series B Preferred Stock issued 
and outstanding is represented by 40 depositary shares, each representing a 1/40th ownership interest in a share of 
the  Series  B  Preferred  Stock  (equivalent  to  a  liquidation  preference  of  $25  per  share).  Each  holder  of  depositary 
shares will be entitled, in proportion to the applicable fraction of a share of Series B Preferred Stock represented by 
such depositary shares, to all rights and preferences of the Series B Preferred Stock represented thereby (including 
dividend,  voting,  redemption,  and  liquidation  rights).  Such  rights  must  be  exercised  through  the  depositary. 
Dividends on the Series B Preferred Stock will be non-cumulative and, if declared, accrue and are payable quarterly, 

111

in arrears, at a rate of 4.450% per annum. The Series B Preferred Stock qualifies as Tier 1 capital for the purposes of 
the regulatory capital calculations. The net proceeds from the issuance and sale of the Series B Preferred Stock, after 
deducting $4.5 million of issuance costs including the underwriting discount and professional service fees, among 
other things, were approximately $145.5 million.

The Series B Preferred Stock is perpetual and has no maturity date. We may redeem the Series B Preferred Stock 
at our option (i) in whole or in part, from time to time, on any dividend payment date on or after December 15, 2025 
or  (ii)  in  whole  but  not  in  part,  within  90  days  following  certain  changes  in  laws  or  regulations  impacting  the 
regulatory capital treatment of the Series B Preferred Stock, in either case, at a redemption price equal to $1,000 per 
share of Series B Preferred Stock (equivalent to $25 per depositary share), plus any declared and unpaid dividends 
for prior dividend periods and accrued but unpaid dividends (whether or not declared) for the then-current dividend 
period  prior  to  but  excluding  the  redemption  date.  If  we  redeem  the  Series  B  Preferred  Stock,  the  depositary  is 
expected redeem a proportionate number of depositary shares. Neither the holders of Series B Preferred Stock nor 
holders  of  depositary  shares  will  have  the  right  to  require  the  redemption  or  repurchase  of  the  Series  B  Preferred 
Stock or the depositary shares.

Series  A  Preferred  Stock.  On  February  15,  2013,  we  issued  and  sold  6,000,000  shares,  or  $150.0  million  in 
aggregate  liquidation  preference,  of  our  5.375%  Non-Cumulative  Perpetual  Preferred  Stock,  Series  A,  par  value 
$0.01 and liquidation preference $25 per share (“Series A Preferred Stock”). On March 16, 2020, we redeemed all of 
the  outstanding  shares  of  our  Series  A  Preferred  Stock  at  a  redemption  price  of  $25  per  share,  or  an  aggregate 
redemption of $150.0 million. When issued, the net proceeds of the Series A Preferred Stock totaled $144.5 million 
after  deducting  $5.5  million  of  issuance  costs  including  the  underwriting  discount  and  professional  service  fees, 
among other things. Upon redemption, these issuance costs were reclassified to retained earnings and reported as a 
reduction of net income available to common shareholders. Prior to redemption, dividends on the Series A Preferred 
Stock were paid quarterly, in arrears, at a rate of 5.375% per annum and the Series A Preferred Stock qualified as 
Tier 1 capital for the purposes of regulatory capital calculations. 

Stock  Repurchase  Plans.  From  time  to  time,  our  board  of  directors  has  authorized  stock  repurchase  plans.  In 
general,  stock  repurchase  plans  allow  us  to  proactively  manage  our  capital  position  and  return  excess  capital  to 
shareholders. Shares purchased under such plans also provide us with shares of common stock necessary to satisfy 
obligations related to stock compensation awards. On January 26, 2022, our board of directors authorized a $100.0 
million stock repurchase plan, allowing us to repurchase shares of our common stock over a one-year period from 
time to time at various prices in the open market or through private transactions. Under prior stock repurchase plans, 
we  repurchased,  177,834  shares  at  a  total  cost  of  $13.7  million  during  2020  and  699,031  shares  at  a  total  cost  of 
$67.2 million during 2019. No shares were repurchased under a stock repurchase plan during 2021. In July 2019, the 
federal bank regulators adopted final rules (the “Capital Simplifications Rules”) that, among other things, eliminated 
the  standalone  prior  approval  requirement  in  the  Basel  III  Capital  Rules  for  any  repurchase  of  common  stock.  In 
certain circumstances, Cullen/Frost’s repurchases of its common stock may be subject to a prior approval or notice 
requirement  under  other  regulations,  policies  or  supervisory  expectations  of  the  Federal  Reserve  Board.  Any 
redemption or repurchase of preferred stock or subordinated debt remains subject to the prior approval of the Federal 
Reserve Board.

Dividend Restrictions. In the ordinary course of business, Cullen/Frost is dependent upon dividends from Frost 
Bank  to  provide  funds  for  the  payment  of  dividends  to  shareholders  and  to  provide  for  other  cash  requirements, 
including to repurchase its common stock. Banking regulations may limit the amount of dividends that may be paid. 
Approval by regulatory authorities is required if the effect of dividends declared would cause the regulatory capital 
of Frost Bank to fall below specified minimum levels. Approval is also required if dividends declared exceed the net 
profits for that year combined with the retained net profits for the preceding two years. Under the foregoing dividend 
restrictions  and  while  maintaining  its  “well  capitalized”  status,  at  December  31,  2021,  Frost  Bank  could  pay 
aggregate dividends of up to $494.1 million to Cullen/Frost without prior regulatory approval.

Under the terms of the junior subordinated deferrable interest debentures that Cullen/Frost has issued to Cullen/
Frost Capital Trust II, Cullen/Frost has the right at any time during the term of the debentures to defer the payment 
of interest at any time or from time to time for an extension period not exceeding 20 consecutive quarterly periods 
with respect to each extension period. In the event that we have elected to defer interest on the debentures, we may 
not, with certain exceptions, declare or pay any dividends or distributions on our capital stock or purchase or acquire 
any of our capital stock.

112

Under the terms of the Series B Preferred Stock, in the event that we do not declare and pay dividends on the 
Series B Preferred Stock for the most recent dividend period, we may not, with certain exceptions, declare or pay 
dividends on, or purchase, redeem or otherwise acquire, shares of our common stock or any of our securities that 
rank junior to the Series B Preferred Stock.

Note 10 - Earnings Per Common Share

Earnings  Per  Common  Share.  Earnings  per  common  share  is  computed  using  the  two-class  method.  Basic 
earnings  per  common  share  is  computed  by  dividing  net  earnings  allocated  to  common  stock  by  the  weighted-
average  number  of  common  shares  outstanding  during  the  applicable  period,  excluding  outstanding  participating 
securities. Participating securities include non-vested stock awards/stock units, deferred stock units and performance 
stock units (during the performance period), though no actual shares of common stock related to any type of stock 
unit  have  been  issued.  Non-vested  stock  awards/stock  units  and  deferred  stock  units  are  considered  participating 
securities  because  holders  of  these  securities  receive  non-forfeitable  dividends  at  the  same  rate  as  holders  of  our 
common stock. Holders of performance stock units receive dividend equivalent payments for dividends paid during 
the performance period at the vesting date of the award based upon the number of units that ultimately vest. Diluted 
earnings  per  common  share  is  computed  using  the  weighted-average  number  of  shares  determined  for  the  basic 
earnings  per  common  share  computation  plus  the  dilutive  effect  of  stock  compensation  using  the  treasury  stock 
method.

The  following  table  presents  a  reconciliation  of  net  income  available  to  common  shareholders,  net  earnings 
allocated  to  common  stock  and  the  number  of  shares  used  in  the  calculation  of  basic  and  diluted  earnings  per 
common share.

Note 11 - Employee Benefit Plans

Retirement Plans

Profit  Sharing  Plan.  Prior  to  2019,  we  maintained  a  qualified  defined  contribution  profit  sharing  plan  that 
covered employees who had completed at least one year of service and were age 21 or older. The Plan was merged 
with  and  into  our  401(k)  plan  effective  January  1,  2019.  We  continue  to  maintain  a  separate  non-qualified  profit 
sharing  plan  for  certain  employees  whose  participation  in  the  qualified  profit  sharing  plan  was  limited.  The  plan 
offers such employees an alternative means of receiving comparable benefits. Expense related to this plan was not 
significant during 2021, 2020 and 2019.

Retirement  Plan  and  Restoration  Plan.  We  maintain  a  non-contributory  defined  benefit  plan  (the  “Retirement 
Plan”) that was frozen as of December 31, 2001. The plan provides pension and death benefits to substantially all 
employees who were at least 21 years of age and had completed at least one year of service prior to December 31, 
2001. Defined benefits are provided based on an employee’s final average compensation and years of service at the 
time the plan was frozen and age at retirement. The freezing of the plan provides that future salary increases will not 

113

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
be  considered.  Our  funding  policy  is  to  contribute  yearly,  at  least  the  amount  necessary  to  satisfy  the  funding 
standards of the Employee Retirement Income Security Act (“ERISA”).

Our Restoration of Retirement Income Plan (the “Restoration Plan”) provides benefits for eligible employees that 
are in excess of the limits under Section 415 of the Internal Revenue Code of 1986, as amended, that apply to the 
Retirement Plan. The Restoration Plan is designed to comply with the requirements of ERISA. The entire cost of the 
plan, which was also frozen as of December 31, 2001, is supported by our contributions.

We use a December 31 measurement date for our defined benefit plans. Combined activity in our defined benefit 

pension plans was as follows: 

Change in plan assets:

Fair value of plan assets at beginning of year
Actual return on plan assets
Employer contributions
Benefits paid

Fair value of plan assets at end of year

Change in benefit obligation:

Benefit obligation at beginning of year
Interest cost

Management  uses  an  asset  allocation  optimization  model  to  analyze  the  potential  risks  and  rewards  associated 
with  various  asset  allocation  strategies  on  a  quarterly  basis.  As  of  December  31,  2021,  management’s  investment 
objective  for  our  defined  benefit  plans  is  to  achieve  long-term  growth.  This  strategy  provides  for  a  target  asset 
allocation  of  approximately  62%  invested  in  equity  securities,  approximately  36%  invested  in  fixed  income  debt 
securities  with  any  remainder  invested  in  cash  or  short-term  cash  equivalents.  The  asset  allocation  optimization 
process provides portfolio allocations which best represent the potential risk associated with a given asset allocation 
over a full market cycle. This is used to help management determine an appropriate mix of assets in order to achieve 
the plan's long term investment goals. The plan assets are reviewed annually to determine if the obligations can be 
met with the current investment mix and funding strategy.

The major categories of assets in our Retirement Plan as of year-end are presented in the following table. Assets 
are  segregated  by  the  level  of  the  valuation  inputs  within  the  fair  value  hierarchy  established  by  ASC  Topic  820 
“Fair  Value  Measurements  and  Disclosures,”  utilized  to  measure  fair  value  (see  Note  17  -  Fair  Value 
Measurements). Our Restoration Plan is unfunded.

Mutual  funds  include  various  equity,  fixed-income  and  blended  funds  with  varying  investment  strategies. 
Approximately  68%  of  mutual  fund  investments  consist  of  equity  investments  as  of  December  31,  2021.  The 
investment objective of equity funds is long-term capital appreciation with current income. The remaining mutual 
fund investments consist of U.S. fixed-income securities, including investment-grade U.S. Treasury securities, U.S. 
government  agency  securities  and  mortgage-backed  securities,  corporate  bonds  and  notes  and  collateralized 
mortgage  obligations.  The  investment  objective  of  fixed-income  funds  is  to  maximize  investment  return  while 
preserving  investment  principal.  Our  investment  strategies  prohibit  selling  assets  short  and  the  use  of  derivatives. 
Additionally, our defined benefit plans do not directly invest in real estate, commodities, or private investments.

The asset allocation optimization model is used to estimate the expected long-term rate of return for a given asset 
allocation  strategy.  Expectations  of  returns  for  each  asset  class  are  based  on  comprehensive  reviews  of  historical 
data and economic/financial market theory. During periods with volatile interest rates and equity security prices, the 
model may call for changes in the allocation of plan investments to achieve desired returns. Management assumed a 
long-term rate of return of 7.25% in the determination of the net periodic benefit cost for 2021. The expected long-
term  rate  of  return  on  assets  was  selected  from  within  the  reasonable  range  of  rates  determined  by  historical  real 
returns,  net  of  inflation,  for  the  asset  classes  covered  by  the  plan’s  investment  policy  and  projections  of  inflation 
over the long-term period during which benefits are payable to plan participants.

We expect to contribute $1.2 million to the defined benefit plans during 2022.

Savings Plans

401(k) Plan and Thrift Incentive Plan. We maintain a 401(k) stock purchase plan that permits each participant to 
make before-tax contributions in an amount not less than 2% and not exceeding 50% of eligible compensation and 
subject to dollar limits from Internal Revenue Service regulations. We match 100% of the employee’s contributions 
to  the  plan  based  on  the  amount  of  each  participant’s  contributions  up  to  a  maximum  of  6%  of  eligible 
compensation.  Eligible  employees  must  complete  30  days  of  service  in  order  to  enroll  and  vest  in  our  matching 
contributions  immediately.  Our  matching  contribution  is  initially  invested  in  the  common  stock  of  Cullen/Frost. 
Employees may immediately reallocate our matching portion, as well as invest their individual contribution, to any 
of a variety of investment alternatives offered under the 401(k) Plan. We may also make discretionary profit sharing 
contributions to eligible participants.

All  profit  contributions  to  the  plan  are  made  at  our  discretion  and  may  be  made  without  regard  to  current  or 
accumulated  profits.  Contributions  are  generally  allocated  to  eligible  participants  uniformly,  based  upon 
compensation,  age  and/or  other  factors.  Plan  participants  self-direct  the  investment  of  allocated  contributions  by 
choosing from a menu of investment options. Profit sharing contributions are subject to withdrawal restrictions and 
participants vest in their allocated contributions after three years of service. Expense related to the plan totaled $23.8 
million in 2021, $17.9 million in 2020 and $28.9 million in 2019.

We maintain a thrift incentive stock purchase plan to offer certain employees whose participation in the 401(k) 
plan  is  limited  an  alternative  means  of  receiving  comparable  benefits.  Expense  related  to  this  plan  was  not 
significant during 2021, 2020 and 2019.

Stock Compensation Plans

We have three active stock compensation plans (the 2005 Omnibus Incentive Plan, the 2007 Outside Directors 
Incentive  Plan  and  the  2015  Omnibus  Incentive  Plan).  All  of  the  plans  have  been  approved  by  our  shareholders. 
During  2015,  the  2015  Omnibus  Incentive  Plan  (“2015  Plan”)  was  established  to  replace  both  the  2005  Omnibus 
Incentive  Plan  (“2005  Plan”)  and  the  2007  Outside  Directors  Incentive  Plan  (the  “2007  Directors  Plan”).  All 
remaining shares authorized for grant under the superseded 2005 Plan and 2007 Directors Plan were transferred to 
the  2015  Plan.  Our  stock  compensation  plans  were  established  to  (i)  motivate  superior  performance  by  means  of 
performance-related  incentives,  (ii)  encourage  and  provide  for  the  acquisition  of  an  ownership  interest  in  our 
company by employees and non-employee directors and (iii) enable us to attract and retain qualified and competent 
persons as employees and to serve as members of our board of directors.

Under  the  2015  Plan,  we  may  grant,  among  other  things,  nonqualified  stock  options,  incentive  stock  options, 
stock awards, stock appreciation rights, restricted stock units, performance share units or any combination thereof to 
certain  employees  and  non-employee  directors.  Any  of  the  authorized  shares  may  be  used  for  any  type  of  award 
allowable under the Plan. The Compensation and Benefits Committee (“Committee”) of our Board of Directors has 
sole authority to (i) establish the awards to be issued, (ii) select the employees and non-employee directors to receive 
awards,  and  (iii)  approve  the  terms  and  conditions  of  each  award  contract.  Each  award  under  the  stock  plans  is 
evidenced by an award agreement that specifies the award price, the duration of the award, the number of shares to 
which  the  award  pertains,  and  such  other  provisions  as  the  Committee  determines.  For  stock  options,  the  option 
price for each grant is at least equal to the fair market value of a share of Cullen/Frost’s common stock on the date of 
grant. Options granted expire at such time as the Committee determines at the date of grant and in no event does the 
exercise period exceed a maximum of ten years. As defined in the plans, outstanding awards may immediately vest 

116

 
 
 
 
 
upon  a  change-in-control  of  Cullen/Frost  and,  in  the  case  of  awards  granted  under  the  2015  Plan,  subsequent 
termination resulting from the change in control.

A  combined  summary  of  activity  in  our  active  stock  plans  is  presented  in  the  table.  Performance  stock  units 
outstanding are presented assuming attainment of the maximum payout rate as set forth by the performance criteria. 
The target award level for performance stock units granted in 2021, 2020 and 2019 was 30,723, 48,409 and 34,317, 
respectively. As of December 31, 2021, there were 777,687 shares remaining available for grant for future awards.

Options awarded to employees generally have a ten-year life and vest in equal annual installments over a four-
year  period.  Non-vested  stock  awards/stock  units  awarded  to  employees  generally  have  a  three-year-cliff  vesting 
period for awards granted in 2021 and a four-year-cliff vesting period for awards granted prior to 2021. Deferred 
stock units awarded to non-employee directors generally have immediate vesting. Upon retirement from our board 
of directors, non-employee directors will receive one share of our common stock for each deferred stock unit held. 
Outstanding non-vested stock units and deferred stock units receive equivalent dividend payments as such dividends 
are declared on our common stock.

Performance stock units represent shares potentially issuable in the future. For performance stock units granted in 
2021, issuance is based upon the measure of our achievement of growth in adjusted net revenue, averaged over the 
three-year  performance  period,  compared  to  the  2021  base-year  amount.  Adjusted  net  revenue  for  the  three-year 
performance period is calculated as the sum of taxable-equivalent net interest income (excluding the effects of PPP 
lending)  and  non-interest  income,  reduced  by  non-interest  expense  (excluding  the  effects  of  PPP  lending)  and  net 
charge-offs. The 2021 base-year adjusted net revenue amount of approximately $426.6 million was calculated as the 
sum  of  taxable-equivalent  net  interest  income  (excluding  the  effects  of  PPP  lending)  and  non-interest  income, 
reduced  by  non-interest  expense  (excluding  the  effects  of  PPP  lending)  and  the  product  of  average  total  loans 
(excluding  PPP  loans)  and  0.30%.  The  ultimate  number  of  shares  issuable  under  each  performance  award  is  the 
product  of  the  award  target  and  the  award  payout  percentage  for  the  given  level  of  achievement.  The  level  of 
achievement  is  measured  as  the  amount  by  which  adjusted  net  revenue,  averaged  over  a  three-year  performance 
period, exceeds the 2021 base-year amount, stated as an average growth percentage. The award payout percentages 
by level of achievement are as follows: (i) less than 13% average growth pays out at 0% of target, (ii) 13% average 
growth pays out at 50% of target, (iii) 19% average growth pays out at 100% of target and (iv) 25% average growth 
or  more  pays  out  at  150%  of  target.  Achievement  between  the  aforementioned  average  growth  percentages  will 
result in an award payout percentage determined based on straight-line interpolation between the percentages.

For  performance  stock  units  granted  prior  to  2021,  issuance  is  based  upon  the  measure  of  our  achievement  of 
relative return on assets over a three-year performance period compared to an identified peer group's achievement of 
relative return on assets over the same three-year performance period. The ultimate number of shares issuable under 
each performance award is the product of the award target and the award payout percentage for the given level of

achievement. The level of achievement is measured as the percentile rank of relative return on assets among the peer 
group. The award payout percentages by level of achievement are as follows: (i) less than 25th percentile pays out at 
0%  of  target,  (ii)  25th  percentile  pays  out  at  50%  of  target,  (iii)  50th  percentile  pays  out  at  100%  of  target  and 
(iv) 75th percentile or more pays out at 150% of target. Achievement between the aforementioned percentiles will 
result in an award payout percentage determined based on straight-line interpolation between the percentiles. 

Performance stock units are eligible to receive equivalent dividend payments as such dividends are declared on 
our  common  stock  during  the  performance  period.  Equivalent  dividend  payments  are  based  upon  the  ultimate 
number  of  shares  issued  under  each  performance  award  and  are  deferred  until  such  time  that  the  units  vest  and 
shares are issued.

Stock-based Compensation Expense. Stock-based compensation expense is recognized ratably over the requisite 
service period for all awards. For most stock option awards, the service period generally matches the vesting period. 
For stock options granted to certain executive officers and for non-vested stock units granted to all participants, the 
service period does not extend past the date the participant reaches 65 years of age. Deferred stock units granted to 
non-employee directors generally have immediate vesting and the related expense is fully recognized on the date of 
grant. For performance stock units, the service period generally matches the three-year performance period specified 
by  the  award,  however,  the  service  period  does  not  extend  past  the  date  the  participant  reaches  65  years  of  age. 
Expense  recognized  each  period  is  dependent  upon  our  estimate  of  the  number  of  shares  that  will  ultimately  be 
issued. 

Stock-based  compensation  expense  and  the  related  income  tax  benefit  is  presented  in  the  following  table.  The

Valuation of Stock-Based Compensation. For the purposes of recognizing stock-based compensation expense, the 
fair value of non-vested stock awards/stock units and deferred stock units is generally the market price of the stock 
on  the  measurement  date,  which,  for  us,  is  the  date  of  the  award.  The  fair  value  of  performance  stock  units  is 
determined in a similar manner except that the market price of the stock on the measurement date is discounted by 
the present value of the dividends expected to be paid on our common stock during the service period of the award 
because dividend equivalent payments on performance stock units are deferred until such time that the units vest and 
shares are issued. In applying this discount to the market price of our stock on the measurement date, we assumed 
we would pay a flat quarterly dividend during the service period equal to our most recent dividend payment, which 
was $0.75, $0.72 and $0.71 in 2021, 2020, and 2019, respectively, discounted at a weighted-average risk-free rate of 
0.77%, 0.19% and 1.65% in 2021, 2020, and 2019, respectively. 

The fair value of employee stock options granted is estimated on the measurement date, which, for us, is the date 
of grant. The fair value of stock options is estimated using a binomial lattice-based valuation model that takes into 
account employee exercise patterns based on changes in our stock price and other variables, and allows for the use 
of dynamic assumptions about interest rates and expected volatility. No stock options have been granted since 2015. 

Note 12 - Other Non-Interest Income and Expense

believes it is more likely than not that all of the deferred tax assets will be realized against deferred tax liabilities and 
projected future taxable income. There were no unrecognized tax benefits during any of the reported periods.

We file income tax returns in the U.S. federal jurisdiction. We are no longer subject to U.S. federal income tax 

examinations by tax authorities for years before 2018.

The fair value of derivative positions outstanding is included in accrued interest receivable and other assets and 
accrued interest payable and other liabilities in the accompanying consolidated balance sheets and in the net change 
in each of these financial statement line items in the accompanying consolidated statements of cash flows.

Interest Rate Derivatives. We utilize interest rate swaps, caps and floors to mitigate exposure to interest rate risk 
and to facilitate the needs of our customers. Our objectives for utilizing these derivative instruments are described 
below:

We have entered into certain interest rate swap contracts that are matched to specific fixed-rate commercial loans 
or leases that we have entered into with our customers. These contracts have been designated as hedging instruments 
to  hedge  the  risk  of  changes  in  the  fair  value  of  the  underlying  commercial  loan/lease  due  to  changes  in  interest 
rates.  The  related  contracts  are  structured  so  that  the  notional  amounts  reduce  over  time  to  generally  match  the 
expected amortization of the underlying loan/lease.

We  have  entered  into  certain  interest  rate  swap,  cap  and  floor  contracts  that  are  not  designated  as  hedging 
instruments. These derivative contracts relate to transactions in which we enter into an interest rate swap, cap and/or 
floor with a customer while at the same time entering into an offsetting interest rate swap, cap and/or floor with a 
third-party financial institution. In connection with each swap transaction, we agree to pay interest to the customer 
on a notional amount at a variable interest rate and receive interest from the customer on a similar notional amount 
at a fixed interest rate. At the same time, we agree to pay a third-party financial institution the same fixed interest 
rate  on  the  same  notional  amount  and  receive  the  same  variable  interest  rate  on  the  same  notional  amount.  The 
transaction  allows  our  customer  to  effectively  convert  a  variable  rate  loan  to  a  fixed  rate.  Because  we  act  as  an 
intermediary  for  our  customer,  changes  in  the  fair  value  of  the  underlying  derivative  contracts  for  the  most  part 
offset each other and do not significantly impact our results of operations.

The notional amounts and estimated fair values of interest rate derivative contracts outstanding at December 31, 
2021 and 2020 are presented in the following table. The fair values of interest rate derivative contracts are estimated 
utilizing internal valuation methods with observable market data inputs, or as determined by the Chicago Mercantile 
Exchange  (“CME”)  for  centrally  cleared  derivative  contracts.  CME  rules  legally  characterize  variation  margin 
payments  for  centrally  cleared  derivatives  as  settlements  of  the  derivatives'  exposure  rather  than  collateral.  As  a 
result, the variation margin payment and the related derivative instruments are considered a single unit of account 
for accounting and financial reporting purposes. Variation margin, as determined by the CME, is settled daily. As a 
result, derivative contracts that clear through the CME have an estimated fair value of zero as of December 31, 2021 
and 2020.

Commodity Derivatives. We enter into commodity swaps and option contracts that are not designated as hedging 
instruments primarily to accommodate the business needs of our customers. Upon the origination of a commodity 
swap  or  option  contract  with  a  customer,  we  simultaneously  enter  into  an  offsetting  contract  with  a  third-party 
financial institution to mitigate the exposure to fluctuations in commodity prices.

The notional amounts and estimated fair values of non-hedging commodity swap and option derivative positions 
outstanding  are  presented  in  the  following  table.  We  obtain  dealer  quotations  and  use  internal  valuation  methods

Foreign  Currency  Derivatives.  We  enter  into  foreign  currency  forward  contracts  that  are  not  designated  as 
hedging  instruments  primarily  to  accommodate  the  business  needs  of  our  customers.  Upon  the  origination  of  a 
foreign currency denominated transaction with a customer, we simultaneously enter into an offsetting contract with a 
third-party financial institution to negate the exposure to fluctuations in foreign currency exchange rates. We also 
utilize foreign currency forward contracts that are not designated as hedging instruments to mitigate the economic 
effect of fluctuations in foreign currency exchange rates on foreign currency holdings and certain short-term, non-
U.S.  dollar  denominated  loans.  The  notional  amounts  and  fair  values  of  open  foreign  currency  forward  contracts

Gains,  Losses  and  Derivative  Cash  Flows.  For  fair  value  hedges,  the  changes  in  the  fair  value  of  both  the 
derivative hedging instrument and the hedged item are included in other non-interest income or other non-interest 
expense. The extent that such changes in fair value do not offset represents hedge ineffectiveness. Net cash flows 
from interest rate swaps on commercial loans/leases designated as hedging instruments in effective hedges of fair 
value  are  included  in  interest  income  on  loans.  For  non-hedging  derivative  instruments,  gains  and  losses  due  to 
changes in fair value and all cash flows are included in other non-interest income and other non-interest expense.

Amounts  included  in  the  consolidated  statements  of  income  related  to  interest  rate  derivatives  designated  as 

hedges of fair value were as follows:

Commercial loan/lease interest rate swaps:

As  stated  above,  we  enter  into  non-hedge  related  derivative  positions  primarily  to  accommodate  the  business 
needs of our customers. Upon the origination of a derivative contract with a customer, we simultaneously enter into 
an offsetting derivative contract with a third-party financial institution. We recognize immediate income based upon 
the difference in the bid/ask spread of the underlying transactions with our customers and the third party. Because 
we act only as an intermediary for our customer, subsequent changes in the fair value of the underlying derivative 
contracts for the most part offset each other and do not significantly impact our results of operations.

Amounts  included  in  the  consolidated  statements  of  income  related  to  non-hedging  interest  rate,  commodity, 

foreign currency and other derivative instruments are presented in the table below.

During 2020, we sold certain non-hedge related, short-term put options on U.S. Treasury securities and realized 
gains  totaling  approximately  $6.0  million  in  connection  with  the  sales.  The  put  options  expired  without  being 
exercised. Gains realized from similar transactions totaled $750 thousand in 2019. These gains are included in the 
table above as a component of non-hedging other derivatives.

Counterparty  Credit  Risk.  Derivative  contracts  involve  the  risk  of  dealing  with  both  bank  customers  and 
institutional  derivative  counterparties  and  their  ability  to  meet  contractual  terms.  Institutional  counterparties  must 
have an investment grade credit rating and be approved by our Asset/Liability Management Committee. Our credit 
exposure  on  interest  rate  swaps  is  limited  to  the  net  favorable  value  and  interest  payments  of  all  swaps  by  each 
counterparty,  while  our  credit  exposure  on  commodity  swaps/options  and  foreign  currency  forward  contracts  is 
limited  to  the  net  favorable  value  of  all  contracts  by  each  counterparty.  Credit  exposure  may  be  reduced  by  the 
amount of collateral pledged by the counterparty. There are no credit-risk-related contingent features associated with 
any of our derivative contracts. Certain derivative contracts with upstream financial institution counterparties may be 
terminated  with  respect  to  a  party  in  the  transaction,  if  such  party  does  not  have  at  least  a  minimum  level  rating 
assigned to either its senior unsecured long-term debt or its deposit obligations by certain third-party rating agencies.

Our  credit  exposure  relating  to  interest  rate  swaps,  commodity  swaps/options  and  foreign  currency  forward 
contracts  with  bank  customers  was  approximately  $118.3  million  at  December  31,  2021.  This  credit  exposure  is 
partly  mitigated  as  transactions  with  customers  are  generally  secured  by  the  collateral,  if  any,  securing  the 
underlying transaction being hedged. Our credit exposure, net of collateral pledged, relating to interest rate swaps, 
commodity swaps/options and foreign currency forward contracts with upstream financial institution counterparties 
was approximately $19.7 million at December 31, 2021. This amount was primarily related to excess collateral we 
posted  to  counterparties.  Collateral  levels  for  upstream  financial  institution  counterparties  are  monitored  and 
adjusted  as  necessary.  See  Note  16  –  Balance  Sheet  Offsetting  and  Repurchase  Agreements  for  additional 
information regarding our credit exposure with upstream financial institution counterparties. At December 31, 2021 
we  had  $110.3  million  in  cash  collateral  related  to  derivative  contracts  on  deposit  with  other  financial  institution 
counterparties.

Note 16 - Balance Sheet Offsetting and Repurchase Agreements

Balance  Sheet  Offsetting.  Certain  financial  instruments,  including  resell  and  repurchase  agreements  and 
derivatives,  may  be  eligible  for  offset  in  the  consolidated  balance  sheet  and/or  subject  to  master  netting 
arrangements  or  similar  agreements.  Our  derivative  transactions  with  upstream  financial  institution  counterparties 
are  generally  executed  under  International  Swaps  and  Derivative  Association  (“ISDA”)  master  agreements  which 
include “right of set-off” provisions. In such cases there is generally a legally enforceable right to offset recognized 
amounts and there may be an intention to settle such amounts on a net basis. Nonetheless, we do not generally offset 
such financial instruments for financial reporting purposes. 

Information  about  financial  instruments  that  are  eligible  for  offset  in  the  consolidated  balance  sheet  as  of 

December 31, 2021 is presented in the following tables.

The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that 
liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a 
principal  market)  for  such  asset  or  liability.  In  estimating  fair  value,  we  utilize  valuation  techniques  that  are 
consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques are 
consistently  applied.  Inputs  to  valuation  techniques  include  the  assumptions  that  market  participants  would  use  in 
pricing  an  asset  or  liability.  ASC  Topic  820  establishes  a  fair  value  hierarchy  for  valuation  inputs  that  gives  the 
highest  priority  to  quoted  prices  in  active  markets  for  identical  assets  or  liabilities  and  the  lowest  priority  to 
unobservable inputs. The fair value hierarchy is as follows:

•

•

•

Level 1 Inputs - Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting 
entity has the ability to access at the measurement date.

Level  2  Inputs  -  Inputs  other  than  quoted  prices  included  in  Level  1  that  are  observable  for  the  asset  or 
liability,  either  directly  or  indirectly.  These  might  include  quoted  prices  for  similar  assets  or  liabilities  in 
active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs 
other  than  quoted  prices  that  are  observable  for  the  asset  or  liability  (such  as  interest  rates,  volatilities, 
prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market 
data by correlation or other means.

Level  3  Inputs  -  Unobservable  inputs  for  determining  the  fair  values  of  assets  or  liabilities  that  reflect  an 
entity’s own assumptions about the assumptions that market participants would use in pricing the assets or 
liabilities.

128

 
 
 
 
 
 
 
 
 
 
In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not 
available,  fair  value  is  based  upon  internally  developed  models  that  primarily  use,  as  inputs,  observable  market-
based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. 
These adjustments may include amounts to reflect counterparty credit quality and our creditworthiness, among other 
things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. Our 
valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or 
reflective  of  future  fair  values.  While  management  believes  our  valuation  methodologies  are  appropriate  and 
consistent  with  other  market  participants,  the  use  of  different  methodologies  or  assumptions  to  determine  the  fair 
value  of  certain  financial  instruments  could  result  in  a  different  estimate  of  fair  value  at  the  reporting  date. 
Furthermore, the reported fair value amounts have not been comprehensively revalued since the presentation dates, 
and therefore, estimates of fair value after the balance sheet date may differ significantly from the amounts presented 
herein. A more detailed description of the valuation methodologies used for assets and liabilities measured at fair 
value is set forth below. Transfers between levels of the fair value hierarchy are recognized on the actual date of the 
event  or  circumstances  that  caused  the  transfer,  which  generally  coincides  with  our  monthly  and/or  quarterly 
valuation process.

Financial  Assets  and  Financial  Liabilities:  Financial  assets  and  financial  liabilities  measured  at  fair  value  on  a 

recurring basis include the following:

Securities  Available  for  Sale.  U.S.  Treasury  securities  are  reported  at  fair  value  utilizing  Level  1  inputs.  Other 
securities classified as available for sale are reported at fair value utilizing Level 2 inputs. For these securities, we 
obtain  fair  value  measurements  from  an  independent  pricing  service.  The  fair  value  measurements  consider 
observable  data  that  may  include  dealer  quotes,  market  spreads,  cash  flows,  the  U.S.  Treasury  yield  curve,  live 
trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms 
and conditions, among other things.

We  review  the  prices  supplied  by  the  independent  pricing  service,  as  well  as  their  underlying  pricing 
methodologies, for reasonableness and to ensure such prices are aligned with traditional pricing matrices. In general, 
we do not purchase investment portfolio securities that are esoteric or that have a complicated structure. Our entire 
portfolio consists of traditional investments, nearly all of which are U.S. Treasury obligations, federal agency bullet 
or  mortgage  pass-through  securities,  or  general  obligation  or  revenue  based  municipal  bonds.  Pricing  for  such 
instruments  is  fairly  generic  and  is  easily  obtained.  From  time  to  time,  we  will  validate  prices  supplied  by  the 
independent  pricing  service  by  comparison  to  prices  obtained  from  third-party  sources  or  derived  using  internal 
models.

Trading Securities. U.S. Treasury securities and exchange-listed common stock are reported at fair value utilizing 
Level 1 inputs. Other securities classified as trading are reported at fair value utilizing Level 2 inputs in the same 
manner as described above for securities available for sale.

Derivatives. Derivatives are generally reported at fair value utilizing Level 2 inputs, except for foreign currency 
contracts, which are reported at fair value utilizing Level 1 inputs. We obtain dealer quotations and utilize internally 
developed  valuation  models  to  value  commodity  swaps/options.  We  utilize  internally  developed  valuation  models 
and/or  third-party  models  with  observable  market  data  inputs  to  validate  the  valuations  provided  by  the  dealers. 
Though there has never been a significant discrepancy in the valuations, should such a significant discrepancy arise, 
we would obtain price verification from a third-party dealer. We utilize internal valuation methods with observable 
market  data  inputs  to  estimate  fair  values  of  customer  interest  rate  swaps,  caps  and  floors.  We  also  obtain  dealer 
quotations for these derivatives for comparative purposes to assess the reasonableness of the model valuations. In 
cases  where  significant  credit  valuation  adjustments  are  incorporated  into  the  estimation  of  fair  value,  reported 
amounts are considered to have been derived utilizing Level 3 inputs.

For  purposes  of  potential  valuation  adjustments  to  our  derivative  positions,  we  evaluate  the  credit  risk  of  our 
counterparties as well as ours. Accordingly, we have considered factors such as the likelihood of our default and the 
default of our counterparties, our net exposures and remaining contractual life, among other things, in determining if 
any fair value adjustments related to credit risk are required. Counterparty exposure is evaluated by netting positions 
that are subject to master netting arrangements, as well as considering the amount of collateral securing the position. 
We review our counterparty exposure on a regular basis, and, when necessary, appropriate business actions are taken 
to adjust the exposure. We also utilize this approach to estimate our own credit risk on derivative liability positions. 
To date, we have not realized any significant losses due to a counterparty’s inability to pay any net uncollateralized 

129

position.  The  change  in  value  of  derivative  assets  and  derivative  liabilities  attributable  to  credit  risk  was  not 
significant during the reported periods.

The  following  tables  summarize  financial  assets  and  financial  liabilities  measured  at  fair  value  on  a  recurring 
basis  as  of  December  31,  2021  and  2020,  segregated  by  the  level  of  the  valuation  inputs  within  the  fair  value

Derivative  assets,  measured  at  fair  value  on  a  recurring  basis  using  significant  unobservable  (Level  3)  inputs 
during  the  reported  periods  consist  of  commodity  swaps  sold  to  loan  customers.  The  significant  unobservable 
(Level  3)  inputs  used  in  the  fair  value  measurement  of  these  commodity  swaps  sold  to  loan  customers  primarily 
relate to the probability of default and loss severity in the event of default. The probability of default is determined 
by the underlying risk grade of the loan (see Note 3 – Loans) underlying the commodity swap in that the probability 
of default increases as a loan’s risk grade deteriorates, while the loss severity is estimated through an analysis of the 
collateral supporting both the underlying loan and commodity swap. Generally, a change in the assumption used for 
the  probability  of  default  is  accompanied  by  a  directionally  similar  change  in  the  assumption  used  for  the  loss 
severity.  As  of  December  31,  2020,  the  weighted-average  risk  grade  of  loans  underlying  commodity  swaps 
measured at fair value using significant unobservable (Level 3) inputs was 14.0. The weighted-average loss severity 
in the event of default on the commodity swaps was 10%. A reconciliation of the beginning and ending balances of 
derivative assets measured at fair value on a recurring basis using significant unobservable (Level 3) inputs is not 
presented as such amounts were not significant during the reported periods.

Certain  financial  assets  and  financial  liabilities  are  measured  at  fair  value  on  a  nonrecurring  basis;  that  is,  the 
instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain 
circumstances  (for  example,  when  there  is  evidence  of  impairment).  Financial  assets  measured  at  fair  value  on  a 
non-recurring  basis  during  the  reported  periods  include  certain  impaired  loans  reported  at  the  fair  value  of  the 
underlying collateral if repayment is expected solely from the collateral. Collateral values are estimated using Level 
2 inputs based on observable market data, typically in the case of real estate collateral, or Level 3 inputs based on 
customized  discounting  criteria,  typically  in  the  case  of  non-real  estate  collateral  such  as  inventory,  oil  and  gas 
reserves, accounts receivable, equipment or other business assets.

The following table presents collateral dependent loans that were remeasured and reported at fair value through a 

specific allocation of the allowance for credit losses on loans based upon the fair value of the underlying collateral:

Non-Financial  Assets  and  Non-Financial  Liabilities:  We  do  not  have  any  non-financial  assets  or  non-financial 
liabilities measured at fair value on a recurring basis. Certain non-financial assets measured at fair value on a non-
recurring  basis  include  foreclosed  assets  (upon  initial  recognition  or  subsequent  impairment),  non-financial  assets 
and non-financial liabilities measured at fair value in the second step of a goodwill impairment test, and intangible 
assets  and  other  non-financial  long-lived  assets  measured  at  fair  value  for  impairment  assessment.  Non-financial 
assets measured at fair value on a non-recurring basis during the reported periods include certain foreclosed assets 
which, upon initial recognition, were remeasured and reported at fair value through a charge-off to the allowance for 
credit losses on loans and certain foreclosed assets which, subsequent to their initial recognition, were remeasured at 
fair  value  through  a  write-down  included  in  other  non-interest  expense.  The  fair  value  of  a  foreclosed  asset  is 
estimated using Level 2 inputs based on observable market data or Level 3 inputs based on customized discounting 
criteria. During the reported periods, all fair value measurements for foreclosed assets utilized Level 2 inputs.

The following table presents foreclosed assets that were remeasured and reported at fair value:

Foreclosed assets remeasured at initial recognition:

allowance  for  credit  losses  on  loans  and  generally  do  not,  and  did  not  during  the  reported  periods,  significantly 
impact  our  credit  loss  expense.  Regulatory  guidelines  require  us  to  reevaluate  the  fair  value  of  other  real  estate 
owned on at least an annual basis. While our policy is to comply with the regulatory guidelines, our general practice 
is to reevaluate the fair value of collateral supporting impaired collateral dependent loans on a quarterly basis. Thus, 
appraisals  are  generally  not  considered  to  be  outdated,  and  we  typically  do  not  make  any  adjustments  to  the 
appraised values.

ASC  Topic  825,  “Financial  Instruments,”  requires  disclosure  of  the  fair  value  of  financial  assets  and  financial 
liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on 
a  recurring  basis  or  non-recurring  basis.  The  estimated  fair  value  approximates  carrying  value  for  cash  and  cash 
equivalents,  accrued  interest  and  the  cash  surrender  value  of  life  insurance  policies.  The  methodologies  for  other 

131

 
 
 
 
 
 
 
financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-
recurring basis are discussed below:

Loans.  The  estimated  fair  value  approximates  carrying  value  for  variable-rate  loans  that  reprice  frequently  and 
with no significant change in credit risk. The fair value of fixed-rate loans and variable-rate loans which reprice on 
an  infrequent  basis  is  estimated  by  discounting  future  cash  flows  using  the  current  interest  rates  at  which  similar 
loans with similar terms would be made to borrowers of similar credit quality. An overall valuation adjustment is 
made for specific credit risks as well as general portfolio credit risk.

Deposits. The estimated fair value approximates carrying value for demand deposits. The fair value of fixed-rate 
deposit  liabilities  with  defined  maturities  is  estimated  by  discounting  future  cash  flows  using  the  interest  rates 
currently offered for deposits of similar remaining maturities. The estimated fair value of deposits does not take into 
account  the  value  of  our  long-term  relationships  with  depositors,  commonly  known  as  core  deposit  intangibles, 
which are separate intangible assets, and not considered financial instruments. Nonetheless, we would likely realize 
a core deposit premium if our deposit portfolio were sold in the principal market for such deposits.

Borrowed Funds. The estimated fair value approximates carrying value for short-term borrowings. The fair value 
of  long-term  fixed-rate  borrowings  is  estimated  using  quoted  market  prices,  if  available,  or  by  discounting  future 
cash  flows  using  current  interest  rates  for  similar  financial  instruments.  The  estimated  fair  value  approximates 
carrying value for variable-rate junior subordinated deferrable interest debentures that reprice quarterly.

Loan Commitments, Standby and Commercial Letters of Credit. Our lending commitments have variable interest 
rates and “escape” clauses if the customer’s credit quality deteriorates. Therefore, the fair values of these items are 
not significant and are not included in the following table.

The estimated fair values of financial instruments that are reported at amortized cost in our consolidated balance 
sheets, segregated by the level of valuation inputs within the fair value hierarchy utilized to measure fair value, were

Under  ASC  Topic  825,  entities  may  choose  to  measure  eligible  financial  instruments  at  fair  value  at  specified 
election  dates.  The  fair  value  measurement  option  (i)  may  be  applied  instrument  by  instrument,  with  certain 
exceptions,  (ii)  is  generally  irrevocable  and  (iii)  is  applied  only  to  entire  instruments  and  not  to  portions  of 
instruments.  Unrealized  gains  and  losses  on  items  for  which  the  fair  value  measurement  option  has  been  elected 
must  be  reported  in  earnings  at  each  subsequent  reporting  date.  During  the  reported  periods,  we  had  no  financial 
instruments measured at fair value under the fair value measurement option.

Note 18 - Operating Segments

We are managed under a matrix organizational structure whereby our two primary operating segments, Banking 
and Frost Wealth Advisors, overlap a regional reporting structure. The regions are primarily based upon geographic 
location and include Austin, Corpus Christi, Dallas, Fort Worth, Houston, Permian Basin, Rio Grande Valley, San 
Antonio and Statewide. We are primarily managed based on the line of business structure. In that regard, all regions 
have the same lines of business, which have the same product and service offerings, have similar types and classes 
of customers and utilize similar service delivery methods. Pricing guidelines for products and services are the same 
across all regions. The regional reporting structure is primarily a means to scale the lines of business to provide a 
local, community focus for customer relations and business development.

Banking  and  Frost  Wealth  Advisors  are  delineated  by  the  products  and  services  that  each  segment  offers.  The 
Banking operating segment includes both commercial and consumer banking services and Frost Insurance Agency. 
Commercial  banking  services  are  provided  to  corporations  and  other  business  clients  and  include  a  wide  array  of 
lending and cash management products. Consumer banking services include direct lending and depository services. 
Frost Insurance Agency provides insurance brokerage services to individuals and businesses covering corporate and 
personal  property  and  casualty  products,  as  well  as  group  health  and  life  insurance  products.  The  Frost  Wealth 
Advisors  operating  segment  includes  fee-based  services  within  private  trust,  retirement  services,  and  financial 
management  services,  including  personal  wealth  management  and  securities  brokerage  services.  A  third  operating 
segment, Non-Banks, is for the most part the parent holding company, as well as certain other insignificant non-bank 
subsidiaries of the parent that, for the most part, have little or no activity. The parent company’s principal activities 
include the direct and indirect ownership of our banking and non-banking subsidiaries and the issuance of debt and 
equity. Our principal source of revenue is dividends from our subsidiaries.

The accounting policies of each reportable segment are the same as those of our consolidated entity except for the 
following items, which impact the Banking and Frost Wealth Advisors segments: (i) expenses for consolidated back-
office  operations  and  general  overhead-type  expenses  such  as  executive  administration,  accounting  and  internal 
audit are allocated to operating segments based on estimated uses of those services, (ii) income tax expense for the 
individual  segments  is  calculated  essentially  at  the  statutory  rate,  and  (iii)  the  parent  company  records  the  tax 
expense or benefit necessary to reconcile to the consolidated total.

We use a match-funded transfer pricing process to assess operating segment performance. The process helps us to 
(i) identify the cost or opportunity value of funds within each business segment, (ii) measure the profitability of a 
particular  business  segment  by  relating  appropriate  costs  to  revenues,  (iii)  evaluate  each  business  segment  in  a 
manner  consistent  with  its  economic  impact  on  consolidated  earnings,  and  (iv)  enhance  asset  and  liability  pricing 
decisions.

Financial results by operating segment are detailed below. Certain prior period amounts have been reclassified to 
conform to the current presentation. Frost Wealth Advisors excludes off-balance-sheet managed and custody assets 
with a total fair value of $43.3 billion, $38.6 billion and $37.8 billion at December 31, 2021, 2020 and 2019.

ASU  2016-02,  “Leases  (Topic  842).”  ASU  2016-02  among  other  things,  requires  lessees  to  recognize  a  lease 
liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; 
and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified 
asset for the lease term. We adopted ASU 2016-02, along with several other subsequent codification updates related 
to lease accounting, as of January 1, 2019. See Note 1 - Summary of Significant Accounting Policies for additional 
information.

ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial 
Instruments.” ASU 2016-13 requires the measurement of all expected credit losses for financial assets held at the 
reporting  date  based  on  historical  experience,  current  conditions,  and  reasonable  and  supportable  forecasts  and 
requires enhanced disclosures related to the significant estimates and judgments used in estimating credit losses, as 
well as the credit quality and underwriting standards of an organization’s portfolio. We adopted ASU 2016-13, as 
subsequently updated for certain clarifications, targeted relief and codification improvements, as of January 1, 2020 
and recognized a cumulative effect adjustment reducing retained earnings by $29.3 million. See Note 1 - Summary 
of Significant Accounting Policies for additional information.

ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350) - Simplifying the Test for Goodwill Impairment.” 
ASU 2017-04 eliminates Step 2 from the goodwill impairment test which required entities to compute the implied 
fair value of goodwill. Under ASU 2017-04, an entity should perform its annual, or interim, goodwill impairment 
test  by  comparing  the  fair  value  of  a  reporting  unit  with  its  carrying  amount.  An  entity  should  recognize  an

impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, 
the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. ASU 2017-04 
became effective for us on January 1, 2020 and did not have a significant impact on our financial statements.

ASU 2017-08, “Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20) - Premium Amortization 
on  Purchased  Callable  Debt  Securities.”  ASU  2017-08  shortens  the  amortization  period  for  certain  callable  debt 
securities  held  at  a  premium  to  require  such  premiums  to  be  amortized  to  the  earliest  call  date  unless  applicable 
guidance related to certain pools of securities is applied to consider estimated prepayments. Under prior guidance, 
entities were generally required to amortize premiums on individual, non-pooled callable debt securities as a yield 
adjustment over the contractual life of the security. ASU 2017-08 does not change the accounting for callable debt 
securities held at a discount. We adopted ASU 2017-08 effective January 1, 2019 and recognized a cumulative effect 
adjustment reducing retained earnings by $14.7 million. See Note 1 - Summary of Significant Accounting Policies 
for additional information.

ASU  2017-12,  “Derivatives  and  Hedging  (Topic  815)  -  Targeted  Improvements  to  Accounting  for  Hedging 
Activities.” ASU 2017-12 amends the hedge accounting recognition and presentation requirements in ASC 815 to 
improve  the  transparency  and  understandability  of  information  conveyed  to  financial  statement  users  about  an 
entity’s risk management activities to better align the entity’s financial reporting for hedging relationships with those 
risk  management  activities  and  to  reduce  the  complexity  of  and  simplify  the  application  of  hedge  accounting. 
ASU  2017-12  became  effective  for  us  on  January  1,  2019  and  did  not  have  a  significant  impact  on  our  financial 
statements. 

ASU  2018-13,  “Fair  Value  Measurement  (Topic  820)  -  Disclosure  Framework-Changes  to  the  Disclosure 
Requirements  for  Fair  Value  Measurement.”  ASU  2018-13  modifies  the  disclosure  requirements  on  fair  value 
measurements in Topic 820. The amendments in this update remove disclosures that no longer are considered cost 
beneficial, modify/clarify the specific requirements of certain disclosures, and add disclosure requirements identified 
as relevant. ASU 2018-13 became effective for us on January 1, 2020 and did not have a significant impact on our 
financial statements.

ASU  2018-14,  “Compensation  -  Retirement  Benefits-Defined  Benefit  Plans-General  (Subtopic  715-20).” 
ASU 2018-14 amends and modifies the disclosure requirements for employers that sponsor defined benefit pension 
or other post-retirement plans. The amendments in this update remove disclosures that no longer are considered cost 
beneficial,  clarify  the  specific  requirements  of  disclosures,  and  add  disclosure  requirements  identified  as  relevant. 
ASU 2018-14 became effective for the year ended December  31, 2020 and did not have a significant impact on our 
financial statements.

ASU  2018-15,  “Intangibles  -  Goodwill  and  Other  -  Internal-Use  Software  (Subtopic  350-40)  -  Customer’s 
Accounting  for  Implementation  Costs  Incurred  in  a  Cloud  Computing  Arrangement  That  Is  a  Service  Contract.” 
ASU  2018-15  clarifies  certain  aspects  of  ASU  2015-05,  “Customer’s  Accounting  for  Fees  Paid  in  a  Cloud 
Computing Arrangement,” which was issued in April 2015. Specifically, ASU 2018-15 aligns the requirements for 
capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements 
for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements 
that include an internal-use software license). ASU 2018-15 does not affect the accounting for the service element of 
a hosting arrangement that is a service contract. ASU 2018-15 became effective for us on January 1, 2020 and did 
not have a significant impact on our financial statements.

ASU  2018-16,  “Derivatives  and  Hedging  (Topic  815)  -  Inclusion  of  the  Secured  Overnight  Financing  Rate 
(“SOFR”) Overnight Index Swap (“OIS”) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes.” The 
amendments in this update permit use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge 
accounting purposes under Topic 815 in addition to the interest rates on direct U.S. Treasury obligations, the LIBOR 
swap  rate,  the  OIS  rate  based  on  the  Fed  Funds  Effective  Rate  and  the  Securities  Industry  and  Financial  Markets 
Association (“SIFMA”) Municipal Swap Rate. ASU 2018-16 became effective for us on January 1, 2019 and did not 
have a significant impact on our financial statements.

ASU 2019-12, “Income Taxes (Topic 740) - Simplifying the Accounting for Income Taxes.” The guidance issued 
in this update simplifies the accounting for income taxes by eliminating certain exceptions to the guidance in ASC 
740 related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim 
period  and  the  recognition  for  deferred  tax  liabilities  for  outside  basis  differences.  ASU  2019-12  also  simplifies 

137

aspects of the accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for 
transactions that result in a step-up in the tax basis of goodwill. ASU 2019-12 became effective for us on January 1, 
2021 and did not have a significant impact on our financial statements.

ASU  2020-04,  “Reference  Rate  Reform  (Topic  848):  Facilitation  of  the  Effects  of  Reference  Rate  Reform  on 
Financial  Reporting.”  ASU  2020-04  provides  optional  expedients  and  exceptions  for  accounting  related  to 
contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. 
ASU  2020-04  applies  only  to  contracts,  hedging  relationships,  and  other  transactions  that  reference  LIBOR  or 
another  reference  rate  expected  to  be  discontinued  because  of  reference  rate  reform  and  do  not  apply  to  contract 
modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging 
relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are 
retained through the end of the hedging relationship. ASU 2020-04 was effective upon issuance and generally can be 
applied  through  December  31,  2022.  The  adoption  of  ASU  2020-04  did  not  significantly  impact  our  financial 
statements.

ASU  2020-08,  “Codification  Improvements  to  Subtopic  310-20,  Receivables  -  Nonrefundable  Fees  and  Other 
Costs.” ASU 2020-08 clarifies the accounting for the amortization of purchase premiums for callable debt securities 
with  multiple  call  dates.  ASU  2020-8  became  effective  for  us  on  January  1,  2021  and  did  not  have  a  significant 
impact on our financial statements.

ASU  2020-09,  “Debt  (Topic  470):  Amendments  to  SEC  Paragraphs  Pursuant  to  SEC  Release  No.  33-10762.” 
ASU 2020-9 amends the ASC to reflect the issuance of an SEC rule related to financial disclosure requirements for 
subsidiary issuers and guarantors of registered debt securities and affiliates whose securities are pledged as collateral 
for  registered  securities.  ASU  2020-09  became  effective  for  us  on  January  4,  2021,  concurrent  with  the  effective 
date of the SEC release, and did not have a significant impact on our financial statements.

ASU  2021-01,  “Reference  Rate  Reform  (Topic  848):  Scope.”  ASU  2021-01  clarifies  that  certain  optional 
expedients and exceptions in ASC 848 for contract modifications and hedge accounting apply to derivatives that are 
affected  by  the  discounting  transition.  ASU  2021-01  also  amends  the  expedients  and  exceptions  in  ASC  848  to 
capture  the  incremental  consequences  of  the  scope  clarification  and  to  tailor  the  existing  guidance  to  derivative 
instruments affected by the discounting transition. ASU 2021-01 was effective upon issuance and generally can be 
applied  through  December  31,  2022.  The  adoption  of  ASU  2021-01  did  not  significantly  impact  our  financial 
statements.

ITEM 9A. CONTROLS AND PROCEDURES

As of the end of the period covered by this Annual Report on Form 10-K, an evaluation was carried out by our 
management, with the participation of our Chief Executive Officer and Chief Financial Officer, of the effectiveness 
of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934). 
Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the disclosure 
controls and procedures were effective as of the end of the period covered by this report. No changes were made to 
our  internal  control  over  financial  reporting  (as  defined  in  Rule  13a-15(f)  under  the  Securities  Exchange  Act  of 
1934) during the last fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal 
control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting

The management of Cullen/Frost Bankers, Inc. is responsible for establishing and maintaining adequate internal 
control  over  financial  reporting.  Our  internal  control  over  financial  reporting  is  a  process  designed  under  the 
supervision of our Chief Executive Officer and Chief Financial Officer to provide reasonable assurance regarding 
the  reliability  of  financial  reporting  and  the  preparation  of  our  financial  statements  for  external  purposes  in 
accordance with generally accepted accounting principles.

As of December 31, 2021, management assessed the effectiveness of our internal control over financial reporting 
based  on  the  criteria  for  effective  internal  control  over  financial  reporting  established  in  “Internal  Control  - 
Integrated  Framework,”  issued  by  the  Committee  of  Sponsoring  Organizations  (“COSO”)  of  the  Treadway 
Commission (“2013 framework”). Based on the assessment, management determined that we maintained effective 
internal control over financial reporting as of December 31, 2021, based on those criteria.

Ernst  &  Young  LLP,  San  Antonio,  Texas,  (U.S.  PCAOB  Auditor  Firm  I.D.:  42),  the  independent  registered 
public  accounting  firm  that  audited  our  consolidated  financial  statements  included  in  this  Annual  Report  on 
Form 10-K, has issued an attestation report on the effectiveness of our internal control over financial reporting as of 
December 31, 2021. The report, which expresses an unqualified opinion on the effectiveness of our internal control 
over financial reporting as of December 31, 2021, is included in this Item under the heading “Attestation Report of 
Independent Registered Public Accounting Firm.”

To the Shareholders and the Board of Directors of Cullen/Frost Bankers, Inc.

Opinion on Internal Control over Financial Reporting

We have audited Cullen/Frost Bankers, Inc.’s internal control over financial reporting as of December 31, 2021, 
based  on  criteria  established  in  Internal  Control  –  Integrated  Framework  issued  by  the  Committee  of  Sponsoring 
Organizations  of  the  Treadway  Commission  (2013  framework)  (the  COSO  criteria).  In  our  opinion,  Cullen/Frost 
Bankers, Inc. (the Company) maintained, in all material respects, effective internal control over financial reporting 
as of December 31, 2021, based on the COSO criteria. 

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board 
(United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2021 and 2020, and

flows for each of the three years in the period ended December 31, 2021, and the related notes and our report dated
