   MANAGEMENT’S DISCUSSION AND ANALYSIS OF 
FINANCIAL CONDITION AND RESULTS OF OPERATIONS 

Management’s discussion and analysis represents an explanation of significant changes in our financial position 
and results of our operations on a consolidated basis for the three-year period ended December 31, 2020. The following 
discussion should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2020, 
and the Selected Financial Data and Consolidated Financial Statements included elsewhere herein. 

Special Cautionary Notice Regarding Forward Looking Information 

Certain matters discussed in this report, excluding historical information, include forward-looking statements, 
within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange 
Act  of  1934,  as  amended,  and  are  subject  to  the  safe  harbor  created  by  these  sections.  Although  we  believe  such 
forward-looking statements are based on reasonable assumptions, no assurance can be given that every objective will be 
reached. The words “estimate,” “expect,” “intend,” “believe” and “project,” as well as other words or expressions of a 
similar meaning, are intended to identify forward-looking statements. Readers are cautioned not to place undue reliance 
on  forward-looking  statements,  which  speak  only  as  of  the  date  of  this  report.  Such  statements  are  based  on  current 
expectations, are inherently uncertain, are subject to risks and should be viewed with caution. Actual results and experience 
may differ materially from the forward-looking statements as a result of many factors. 

Risk factors that could cause actual results to differ materially from any results that we project, forecast, estimate 

or budget in forward-looking statements include, among others, the following possibilities: 

•  Local, regional, national and international economic business conditions and the impact they may have on 
us, our customers, and such customers’ ability to transact profitable business with us, including the ability of 
our borrowers to repay their loans according to their terms or a change in the value of the related collateral. 

•  Volatility and disruption in national and international financial markets. 

•  Government intervention in the U.S. financial system. 

•  The unavailability of funding from the FHLB, the Fed or other sources in the future could adversely impact 

our growth strategy, prospects and performance.

margins. 

•  Changes  in  state  and/or  federal  laws  and  regulations,  including,  the  impact  of  the  Consumer  Financial 
Protection  Bureau  (“CFPB”)  as  a  regulator  of  financial  institutions,  changes  in  the  accounting,  tax  and 
regulatory treatment of trust preferred securities, as well as changes in banking, tax, securities, insurance, 
employment, environmental and immigration laws and regulations and the risk of litigation that may follow. 

•  Changes in U.S.—Mexico trade, including, reductions in border crossings and commerce, integration and 
implementation of the  United States-Mexico-Canada Agreement and the possible imposition of tariffs on 
imported goods. 

•  The reduction of deposits from nonresident alien individuals due to the IRS rules requiring U.S. financial 

institutions to report deposit interest payments made to such individuals. 

•  The loss of senior management or operating personnel. 

•  The  timing,  impact  and  other  uncertainties  of  the  potential  future  acquisitions,  as  well  as  our  ability  to 

maintain our current branch network and enter new markets to capitalize on growth opportunities. 

•  Changes  in  estimates  of  future  reserve  requirements  based  upon  periodic  review  thereof  under  relevant 

regulatory and accounting requirements.

•  Additions to our allowance for credit loss as a result of changes in local, national or international conditions 

which adversely affect our customers. 

•  Greater than expected costs or difficulties related to the development and integration of new products and 

lines of business. 

• 

• 

Increased  labor  costs  and  effects  related  to  health  care  reform  and  other  laws,  regulations  and  legal 
developments impacting labor costs.

available-for-sale portfolios. 

•  The effect of changes in accounting policies and practices by the Public Company Accounting Oversight 

Board, the Financial Accounting Standards Board and other accounting standards setters. 

•  The costs and effects of regulatory developments or regulatory or other governmental inquiries and the results 

of regulatory examinations or reviews and obtaining regulatory approvals. 

•  The effect of final rules amending Regulation E that prohibit financial institutions from charging consumer 
fees for paying overdrafts on ATM and one-time debit card transactions, as well as the effect of any other 
regulatory or legal developments that limit overdraft services. 

•  The reduction of income and possible increase in required capital levels related to the adoption of legislation, 
including and the implementing rules and regulations, including those that establish debit card interchange 
fee standards and prohibit network exclusivity arrangements and routing restrictions. 

•  The  increase  in  required  capital  levels  related  to  the  implementation  of  capital  and  liquidity  rules  of  the

2019 (“COVID-19”) or similar global pandemics. 

Forward-looking statements speak only as of the date on which such statements are made. It is not possible to 
foresee or identify all such factors. We make no commitment to update any forward-looking statement, or to disclose any

Overview 

We  are  headquartered  in  Laredo,  Texas,  with  187  facilities  and  282  ATMs,  providing  banking  services  for 
commercial, consumer and international customers of north, south, central and southeast Texas and the State of Oklahoma. 
We  are  one  of  the  largest  independent  commercial  bank  holding  companies  headquartered  in  Texas.  We,  through  our 
Subsidiary Banks, are in the business of gathering funds from various sources and investing those funds in order to earn a 
return. We, either directly or through a Subsidiary Bank, own one insurance agency, a liquidating subsidiary, a fifty percent 
interest in an investment banking unit that owns a broker/dealer, a controlling interest in four merchant banking entities, 
and a majority ownership in a real-estate development partnership. Our primary earnings come from the spread between 
the interest earned on interest-bearing assets and the interest paid on interest-bearing liabilities. In addition, we generate 

3 

 
 
 
income from fees on products offered to commercial, consumer and international customers.  The sales team of each of 
our Subsidiary Banks aims to match the right mix of products and services to each customer to best serve the customer’s 
needs.  That process entails spending time with customers to assess those needs and servicing the sales arising from those 
discussions  on  a  long-term  basis.    Our  Subsidiary  Banks  have  various  compensation  plans,  including  incentive-based 
compensation, for fairly compensating employees.  Our Subsidiary Banks also have a robust process in place to review 
sales that support the incentive-based compensation plan to monitor the quality of the sales and identify any significant 
irregularities, a process that has been in place for many years. 

One of our primary goals is to grow net interest income and non-interest income while adequately managing 
credit risk, interest rate risk and expenses. Effective management of capital is one of our critical objectives. A key measure 
of the performance of a banking institution is the return on average common equity (“ROE”). Our ROE for the year ended 
December 31, 2020 was 7.86% as compared to 9.97% for the year ended December 31, 2019. 

We are very active in facilitating trade along the United States border with Mexico. We do a large amount of 
business with customers domiciled in Mexico and deposits from persons and entities domiciled in Mexico comprise a large 
and stable portion of the deposit base of our Subsidiary Banks. We also serve the growing Hispanic population through 
our facilities located throughout north, south, central and southeast Texas and the State of Oklahoma. 

In March 2020, the World Health Organization recognized the outbreak of COVID-19 as a pandemic.  The spread 
of  COVID-19  and  resulting  global  health  crisis  has  created  extreme  negative  consequences  and  disruption  in  global 
financial markets and has curtailed activity in the governmental, commercial and consumer sectors.  Government responses 
at all levels have included ordering non-essential businesses be closed, mandating that individuals not working in essential 
businesses restrict their movement, requiring the observance of social distancing and sheltering in place, and, in many 
communities,  cancelling  what  remained  of  the  school  year.   The  consequences  of  these  actions,  and  the  responses  by 
individuals and businesses affected, has resulted in rapid decreases in consumer and commercial activity, rapid increases 
in  unemployment,  disruption  in  global  supply  chains,  market  downturns  and  volatility,  drastic  changes  in  consumer 
behavior, new legislation in response to the emergency and decreases in interest rates.   

We have continued to work with our customers to assist them through these difficult times and we are capitalizing 
on our strong capital position and strong liquidity to ensure that we are correctly positioned and have the financial strength 
to navigate the crisis to protect our Company, our employees, our customers and our shareholders.  In order to protect the 
health of our employees and customers, while still filling the needs in the communities we serve as an essential business, 
we have taken steps to ensure proper safety protocols are in place, including enforcing local ordinances, discontinuing 
significant travel, ensuring social distancing, increasing disinfecting of facilities, establishing a human resources hotline 
to address employee concerns and establishing a task force to ensure we are making good decisions.  For our customers, 
we are also working with them on a case-by-case basis on temporary deferrals of interest and/or principal payments on 
loans and responding to other individual needs of those customers in distress.   

On March 27, 2020, the Coronavirus Aid, Relief and Economic Security (“CARES”) Act was signed into law.  It 
contains substantial tax and spending provisions intended to address the impact of the COVID-19 pandemic.  The CARES 
Act includes the Paycheck Protection Program (“PPP”), originally a nearly $350 billion program designed to aid small 
businesses through federally guaranteed loans distributed through banks.  These loans were originally intended to support 
eight weeks of payroll and certain other costs to help those businesses remain viable and allow their employees to pay 
their  bills.    Subsequently,  on  April 24,  2020,  the  Paycheck  Protection  Program  and  Health  Care  Enhancement  Act 
(“CARES  Part  II”)  was  signed  into  law.    CARES  Part  II  provided  an  additional  funding  of  $320  billion  for  the  PPP 
program.  Then, on June 5, 2020, the Paycheck Protection Program Flexibility Act (“PPPFA”) was signed into law.  The 
PPPFA, among other things, extended the period of time that businesses could spend PPP loan proceeds on payroll and 
other  eligible  costs  from  eight  weeks  to  the  earlier  of  24  weeks  or  December 31,  2020.    On  December 27,  2020,  the 
Economic Aid to Hard-Hit Small Businesses, Nonprofits and Venues Act (the “Economic Aid Act”) was enacted, which 
among other things, reauthorized lending under the PPP to first-time borrowers and for second draws by certain borrowers 
who have previously received PPP loans.  The Economic Aid Act made available an additional $147 billion for PPP loans 
requested by March 31, 2021.  We have been active participants in helping our customers obtain PPP loans under all the 
PPP programs, and as of February 22, 2021, have approximately 3,500 loans with an approximate value of $395,872,000 
outstanding.

Future economic conditions remain uncertain and the impact of those conditions on our business also remains 
uncertain.  Our business depends on the willingness and ability of our customers to conduct banking and other financial 
transactions.  Our revenue streams including service charges on deposits and banking and non-banking service charges 
and fees (ATM and interchange income) have been impacted and may continue to be impacted in the future if economic 
conditions do not improve.  Expense control has been a long-time focus and essential element to our long-term profitability.  
We have kept that focus in mind as we continue to look at operations and create efficiencies and institute cost-control 
protocols at all levels.  We will continue to monitor our efficiency ratio, a measure of non-interest expense to net interest 
income plus non-interest income and our overhead burden ratio, a ratio of our operating expenses against total assets, 
closely.  We use these measures in determining if we are accomplishing our long-term goals of controlling our costs in 
order to provide superior returns to our shareholders.

Net Income 

Net income for the year ended December 31, 2020 decreased by 18.4% compared to the same period of 2019.  
Net income for the year ended December 31, 2020 was primarily impacted by an increase in the provision for credit losses 
due  to  the  economic  changes  that  occurred  in  2020  as  a  result  of  COVID-19  and  the  impact  of  those  changes  on  our 
Allowance for Credit Losses (“ACL”) calculation for the period.  We adopted the provisions of Accounting Standards 
Update  No. 2016-13,  “Financial  Instruments –  Credit  Losses:  (“ASU  2016-13”)  on  January 1,  2020,  resulting  in  a 
transition from the long-standing incurred loss model to an expected credit loss model, which recognizes credit losses over 
the life of a financial asset.  Expected credit losses capture historical information, current conditions, and reasonable and

supportable forecasts of future conditions.  The impact of the adoption resulted in a charge to capital of $8.3 million, net 
of tax.  The provision for credit losses for the year ended December 31, 2020 was approximately $35.8 million, after tax, 
an increase of 140.8% compared to the same period of 2019.  Net interest income for the year ended December 31, 2020 
was also negatively impacted by the Federal Reserve Board (“FRB”) action to decrease interest rates in March 2020.  Net 
income for the year ended December 31, 2019 decreased by 5% compared to the same period of 2018.  Net interest income 
was positively affected by an increase in net interest income due to a higher volume of loans and an increase in the overall 
yield on the portfolio.  Interest expense increased for the year ended December 31, 2019 and can be primarily attributed 
to an increase in the cost of borrowings, and an increase in the interest paid on savings and time deposit accounts, which 
increased because of the FRB actions to increase interest rates in 2019.  Net income for the year ended December 31, 2019 
was negatively impacted by an increase in the provision for credit losses due to a charge-off of $7.5 million, net of tax, on 
a relationship that was secured by real property on which car dealerships are operated.  

Net Interest Income 

Net interest income is the spread between income on interest-earning assets, such as loans and securities, and the 
interest expense on liabilities used to fund those assets, such as deposits, repurchase agreements and funds borrowed. Net 
interest income is our largest source of revenue. Net interest income is affected by both changes in the level of interest 
rates and changes in the amount and composition of interest-earning assets and interest-bearing liabilities. Tax-exempt 
yields have not been adjusted to a tax-equivalent basis.

The level of interest rates and the volume and mix of earning assets and interest-bearing liabilities impact net 
income  and net  interest  margin.  The  yield on  average  interest-earning  assets  decreased  22.0% from 4.77%  in 2019  to 
3.72% in 2020, and the rates paid on average interest-bearing liabilities decreased 36.6% from 0.93% in 2019 to 0.59% in 
2020. The yield on average interest-earning assets increased 7.0% from 4.46% in 2018 to 4.77% in 2019, and the rates 
paid  on  average  interest-bearing  liabilities  increased  17.7%  from  .79%  in  2018  to  .93%  in  2019.  The  majority  of  our 
taxable investment securities are invested in mortgage backed securities and, during rapid increases or reduction in interest 
rates, the yield on these securities do not re-price as quickly as the loans.

(1)  The change in interest due to both rate and volume has been allocated to volume and rate changes in proportion to the relationship of the absolute 
dollar amounts of the change in each. 

As part of our strategy to manage interest rate risk, we strive to manage both assets and liabilities so that interest 
sensitivities match. One method of calculating interest rate sensitivity is through gap analysis. A gap is the difference 
between the amount of interest rate sensitive assets and interest rate sensitive liabilities that re-price or mature in a given 
time period. Positive gaps occur when interest rate sensitive assets exceed interest rate sensitive liabilities, and negative 
gaps occur when interest rate sensitive liabilities exceed interest rate sensitive assets. A positive gap position in a period 
of rising interest rates should have a positive effect on net interest income as assets will re-price faster than liabilities. 
Conversely, net interest income should contract somewhat in a period of falling interest rates. Our management can quickly 
change our interest rate position at any given point in time as market conditions dictate. Additionally, interest rate changes 
do  not  affect  all  categories  of  assets  and  liabilities  equally  or  at  the  same  time.  Analytical  techniques  we  employ  to 
supplement gap analysis include simulation analysis to quantify interest rate risk exposure. The gap analysis prepared by 
management is reviewed by our Investment Committee at least twice a year. The Investment Committee is comprised of 
certain members of the board of directors and senior managers of the various Subsidiary Banks. Management currently 
believes that we are properly positioned for interest rate changes; however, if management determines at any time that we 
are not properly positioned, we will strive to adjust the interest rate sensitive assets and liabilities in order to manage the 
effect of interest rate changes. 

We have established guidelines for acceptable volatility of projected net interest income on the income simulation 
analysis and the guidelines are reviewed at least annually. As of December 31, 2020, in rising rate scenarios of +100, 
+200, +300 and +400 basis points, the guidelines established by management require that the net interest income not vary

by more than minus 30%, 30%, 30%, and 40%, respectively. Given the current low interest rate environment, no downward 
rate shifts were modeled in our income simulations.  At December 31, 2020, the income simulations show that a rate shift 
of +100, +200, +300 and +400 basis points in interest rates up will vary projected net interest income for the coming 
12-month period by +11.59%, +24.98%, +37.86%, and +50.41%, respectively. The basis point shift in interest rates is a 
hypothetical rate scenario used to calibrate risk and does not necessarily represent management’s current view of future 
market developments. We believe that we are properly positioned for a potential interest rate increase or decrease.

Domestic loans accounted for on a non-accrual basis increased at December 31, 2020 by 305.7% compared to 
the same period of 2019.  The increase can be primarily attributed to one relationship secured by commercial property.  
Domestic loans contractually past due ninety days and still accruing decreased by 87.2% at December 31, 2020 compared 
to the same period of 2019 and can be attributed to a relationship that is secured by real property on which education 
centers are operated.   

The ACL increased 80.9% to $109,059,000 at December 31, 2020 from $60,278,000 at December 31, 2019.  The 
ACL  was  1.45%  of  total  loans,  net  of  unearned  income  at  December 31,  2020  and  .87%  at  December 31,  2019.  The 
provision for credit losses charged to expense increased $26,536,000 to $45,379,000 for the year ended December 31, 
2020  from  $18,843,000  for  the  same  period  in  2019.    The  increase  in  the  ACL  can  be  primarily  attributed  to  the 
deteriorating economic conditions occurring in those periods as a result of COVID-19 and the impact of those conditions 
on certain segments of our calculation.  We adopted the provisions of ASU 2016-13 on January 1, 2020, resulting in a 
transition from the long-standing incurred loss model to an expected credit loss model, which recognizes credit losses over 
the life of a financial asset.

The gross income that would have been recorded during 2020, 2019 and 2018 on non-accrual loans in accordance 
with  their  original  contract  terms  was  approximately  $694,000,  $340,000  and  $1,119,000  on  domestic  loans  and 
approximately  $0,  $0,  and  $0  on  foreign  loans,  respectively.  The  amount  of  interest  income  on  such  loans  that  was 
recognized in 2020, 2019 and 2018 was approximately $0, $4,000, and $4,000 on domestic loans and $0, $0, and $0 for 
foreign loans, respectively. 

Generally, loans are placed on non-accrual status if principal or interest payments become 90 days past due and/or 
management  deems  the  collectability  of  the  principal  and/or  interest  to  be  in  question,  as  well  as  when  required  by 
applicable  regulatory  guidelines.  Interest  income  on  non-accrual  loans  is  recognized  only  to  the  extent  payments  are 
received or when, in management’s opinion, the creditor’s financial condition warrants reestablishment of interest accruals. 
Under special circumstances, a loan may be more than 90 days delinquent as to interest or principal and not be placed on 
non-accrual status. This situation generally results when a Subsidiary Bank has a borrower who is experiencing financial 
difficulties, but not to the extent that requires a restructuring of indebtedness. The majority of this category is composed 
of loans that are considered to be adequately secured and/or for which there has been a recent history of payments. When 
a loan is placed on non-accrual status, any interest accrued, not paid, is reversed and charged to operations against interest 
income. 

Loan  commitments,  consisting  of  unused  commitments  to  lend,  letters  of  credit,  credit  card  lines  and  other 
approved loans, that have not been funded, were approximately $2,486,311,000 and $2,758,132,000 at December 31, 2020 
and 2019, respectively. See Note 19 to the Consolidated Financial Statements.

The ACL primarily consists of the aggregate ACL’s of the Subsidiary Banks. The ACL’s are established through 

charges to operations in the form of provisions for credit losses. 

The Subsidiary Banks charge-off that portion of any loan which management considers to represent a loss as well 
as that portion of any other loan which is classified as a “loss” by bank examiners. Commercial, financial and agricultural 
or real estate loans are generally considered by management to represent a loss, in whole or part, (i) when an exposure 
beyond  any  collateral  coverage  is  apparent,  (ii) when  no  further  collection  of  the  portion  of  the  loan  so  exposed  is 
anticipated  based  on  actual  results,  (iii) when  the  credit  enhancements,  if  any,  are  not  adequate,  and  (iv) when  the 
borrower’s financial condition would so indicate. Generally, unsecured consumer loans are charged-off when 90 days past 
due. The increase in charge-offs charged to the ACL for the year ended December 31, 2019 can be primarily attributed to 
a relationship that is secured by multiple pieces of real property on which car dealerships are operated.  The relationship 
began deteriorating in the fourth quarter of 2018, triggered by significant fraud by a high-level insider of the car dealership 
resulting  in  the  dealerships  unexpectedly  filing  for  bankruptcy  and  creating  an  exposure  for  potential  loss  since  the 
operations of the dealerships were the source of repayment from the borrower.  The relationship further deteriorated in the 
first quarter of 2019 after the court approved debtor in possession plan sponsor discontinued its role in the process and 
thus did not fulfill its obligation to assume full responsibility of the accrued and unpaid interest.  Although the relationship 
is secured by real property (the dealerships’ real estate), the real property has specialized use, contributing to the potential 
exposure for probable loss.  During the first quarter of 2019, in light of the circumstances and management’s evaluation 
of the relationship, the decision was made to classify the relationship as doubtful (formerly “impaired” prior to the adoption 
of ASU 2016-13), non-accrual status and place a specific reserve on the relationship in the amount of $9.5 million.  During 
the second quarter of 2019, management continued to evaluate the relationship and decided to foreclose on the underlying 
real estate collateral, resulting in a charge-off of approximately $9.5 million, reflected in the tables above as part of the 
Commercial and commercial real estate:  farmland and commercial categories.  As discussed in prior periods, charge-offs 
for the twelve-months ended December 31, 2016 had increased due to the deterioration of one relationship that was secured 
by multiple pieces of transportation equipment beginning in the fourth quarter of 2014.  In March 2016, litigation against 
the management of the borrower was filed in the State of Nevada, resulting in a going concern issue with the borrower’s 
operations  and  the  future  use  of  the  transportation  equipment  pledged  as  collateral  on  the  relationship.    As  a  result, 
management, in accordance with its credit review procedures, re-evaluated the collateral values on the equipment in light 
of  the  new  circumstances  and  reduced  the  collateral  values  accordingly,  resulting  in  a  further  charge-down  of  the 
relationship of approximately $19.4 million, which is included in the losses charged to the allowance in the commercial 
category in the table detailing the activity for the twelve months ended December 31, 2016.  Two recoveries on loans 
charged-off in prior years are included in the recoveries credited to the allowance in the table detailing activity for the year 
ended December 31, 2016.  The recoveries occurred in the first and third quarters of 2016 in the amounts of $4.4 million 
and $6 million, respectively, and are included in the Commercial and commercial real estate: other construction and land 
development categories.

The  ACL  is  a  reserve  established  through  a  provision  for  credit  losses  charged  to  expense,  which  represents 
management’s best estimate of credit losses within the existing portfolio of loans based on our internal ACL calculation. 
While our management considers that it is generally able to identify borrowers with financial problems reasonably early 
and to monitor credit extended to such borrowers carefully, there is no precise method of predicting credit losses. The 
determination that a loan is likely to be uncollectible and that it should be wholly or partially charged-off as a loss is an 
exercise of judgment. Similarly, the determination of the adequacy of the ACL can be made only on a subjective basis. 
Our management believes that the ACL at December 31, 2020 was adequate to absorb probable losses from loans and 
other financial instruments in the portfolio at that date. See Critical Accounting Policies on page 22.

Total non-interest income for the year ended December 31, 2020 decreased by 2.7% compared to the same period 
of  2019.    Income  from  service  charges  on  deposit  accounts  for  the  year  ended  December 31,  2020  were  negatively 
impacted due to a decrease in customer activity as a result of the current economic environment and the continued impact 
of  the  COVID-19  pandemic  on  day-to-day  activities.    Non-interest  income  for  the  year  ended  December 31,  2019 
decreased by 6.2% compared to the same period of 2018.  The decrease can be primarily attributed to a decrease in non-
interest income from other investments due to the impairment of an equity investment of $3.7 million, net of tax as a result 
of a re-evaluation of the carrying value and losses on various equity investments in which we hold an ownership.

Non-interest expense for the year ended December 31, 2020 decreased by 9.2% compared to the same period of 
2019.  The decrease is primarily due to our employee compensation and benefit reductions, and is primarily being driven 
by efforts to right-size and closely manage our workforce commensurate with decreased activities in our branches arising

from the COVID-19 pandemic, while ensuring that we are able to continue to serve our customers.  Non-interest expense 
for the year ended December 31, 2019 increased by 3.4% compared to the same period of 2018.  Non-interest expense was 
impacted by an increase in costs of our compensation and benefit plans as a result of our continued review of those plans 
and necessary increases to remain competitive and compensate our staff based on their performance, as well as an increase 
in depreciation expense as we continue to invest in our network infrastructure, equipment and facilities.  Professional fees 
increased in 2019 compared to the same period of 2018 primarily due to ongoing costs related to strategic projects across 
our entities to enhance efficiencies and workflow.     

Effects of Inflation 

The principal component of earnings is net interest income, which is affected by changes in the level of interest 
rates. Changes in rates of inflation affect interest rates. It is difficult to precisely measure the impact of inflation on net 
interest income because it is not possible to accurately differentiate between increases in net interest income resulting from 
inflation and increases resulting from increased business activity. Inflation also raises costs of operations, primarily those 
of employment and services.

Mortgage-backed  securities  are  securities  primarily  issued  by  the  Federal  Home  Loan  Mortgage  Corporation 
(“Freddie  Mac”),  Federal  National  Mortgage  Association  (“Fannie  Mae”),  and  the  Government  National  Mortgage 
Association (“Ginnie Mae”). Investments in mortgage-backed securities issued by Ginnie Mae are fully guaranteed by the 
U.S.  government.  Investments  in  mortgage-backed  securities  issued  by  Freddie  Mac  and  Fannie  Mae  are  not  fully 
guaranteed by the U.S. government; however, we believe that the quality of the bonds is similar to other AAA rated bonds 
with  limited  credit  risk, particularly given  the  placement of Fannie  Mae  and Freddie  Mac  into  conservatorship by  the 
federal government in 2008 and because securities issued by others that are collateralized by residential mortgage-backed 
securities issued by Fannie Mae or Freddie Mac are rated consistently as AAA rated securities.

On December 31, 2020, we had $138,970,000 (1.0% of total assets) in loans outstanding to borrowers domiciled 
in foreign countries, which included primarily borrowers domiciled in Mexico. The loan policies of our Subsidiary Banks 
generally require that loans to borrowers domiciled in foreign countries be primarily secured by assets located in the United 
States or have credit enhancements in the form of guarantees from significant United States corporations. The composition 
of such loans and the related amounts of allocated ACL as of December 31, 2020 and 2019 is presented below.

We offer a variety of deposit accounts having a wide range of interest rates and terms. We rely primarily on our 
high-quality  customer  service,  sales  programs,  customer  referrals  and  advertising  to  attract  and  retain  these  deposits. 
Deposits provide the primary source of funding for our lending and investment activities, and the interest paid for deposits 
must be managed carefully to control the level of interest expense. Deposits at December 31, 2020 were $10,721,860,000,

an increase of 21.5% from $8,826,034,000 at December 31, 2019.  Deposits during the current economic environment 
have increased as customers have received proceeds from CARES Act programs, such as stimulus payments and PPP loan 
proceeds, and presumably decided to save and preserve cash instead of spending during these uncertain times.   

Other Borrowed Funds 

Other borrowed funds include FHLB borrowings which may be short-term and long-term borrowings issued by 
the FHLB of Dallas and the FHLB of Topeka at the market price offered at the time of funding.  These borrowings are 
secured by residential mortgage-backed investment securities and a portion of our loan portfolio.  At December 31, 2020, 
other borrowed funds totaled $436,327,000, a decrease of 30.4% from $626,511,000 at December 31, 2019.  The decrease 
in borrowings can be attributed to an increase in cash arising from principal pay downs on available-for-sale debt securities 
and deposits.

Liquidity and Capital Resources 

Liquidity 

The maintenance of adequate liquidity provides our Subsidiary Banks with the ability to meet potential depositor 
withdrawals,  provide  for  customer  credit  needs,  maintain  adequate  statutory  reserve  levels  and  take  full  advantage  of 
high-yield  investment  opportunities  as  they  arise.  Liquidity  is  afforded  by  access  to  financial  markets  and  by  holding 
appropriate amounts of liquid assets. Our Subsidiary Banks derive their liquidity largely from deposits of individuals and 
business entities. Other important funding sources for our Subsidiary Banks during 2020 and 2019 were borrowings from 
the FHLB, securities sold under repurchase agreements and large certificates of deposit, requiring management to closely 
monitor its asset/liability mix in terms of both rate sensitivity and maturity distribution. Our Subsidiary Banks have had a 
long-standing relationship with the FHLB and keep open, unused, lines of credit in order to fund liquidity needs. In the 
event that the FHLB indebtedness is not renewed, the repayment of the outstanding indebtedness would more than likely 
be repaid through proceeds generated from the sales of unpledged available-for-sale securities. We maintain a sizable, 
high quality investment portfolio to provide significant liquidity. These securities can be sold or sold under agreements to 
repurchase, to provide immediate liquidity. As in the past, we will continue to monitor the volatility and cost of funds in 
an attempt to match maturities of rate-sensitive assets and liabilities and respond accordingly to anticipated fluctuations in 
interest rates over reasonable periods of time. 

Asset/Liability Management 

Our  funds  management  policy  has  as  its  primary  focus  the  measurement  and  management  of  the  Subsidiary 
Banks’ earnings at risk in the face of rising or falling interest rate forecasts. The earliest and most simplistic concept of 
earnings at risk measurement is the gap report, which is used to generate a rough estimate of the vulnerability of net interest 
income to changes in market rates as implied by the relative re-pricings of assets and liabilities. The gap report calculates

the difference between the amounts of assets and liabilities re-pricing across a series of intervals in time, with emphasis 
typically placed on the one-year period. This difference, or gap, is usually expressed as a percentage of total assets. 

If an excess of liabilities over assets matures or re-prices within the one-year period, the statement of condition 
is said to be negatively gapped. This condition is sometimes interpreted to suggest that an institution is liability-sensitive, 
indicating that earnings would suffer from rising rates and benefit from falling rates. If a surplus of assets over liabilities 
occurs in the one-year time frame, the statement of condition is said to be positively gapped, suggesting a condition of 
asset sensitivity in which earnings would benefit from rising rates and suffer from falling rates. 

The gap report thus consists of an inventory of dollar amounts of assets and liabilities that have the potential to 
mature or re-price within a particular period. The flaw in drawing conclusions about interest rate risk from the gap report 
is that it takes no account of the probability that potential maturities or re-pricings of interest-rate-sensitive accounts will 
occur, or at what relative magnitudes. Because simplicity, rather than utility, is the only virtue of gap analysis, financial 
institutions increasingly have either abandoned gap analysis or accorded it a distinctly secondary role in managing their 
interest-rate risk exposure. 

The  net  interest  rate  sensitivity  at  December 31,  2020,  is  illustrated  in  the  following  table.  This  information 
reflects the balances of assets and liabilities whose rates are subject to change. As indicated in the table below, we are 
asset sensitive through all of the time periods illustrated. The table shows the sensitivity of the statement of condition at 
one point in time and is not necessarily indicative of the position at future dates.

The detailed inventory of statement of condition items contained in gap reports is the starting point of income 
simulation analysis. Income simulation analysis also focuses on the variability of net interest income and net income, but 
without the limitations of gap analysis. In particular, the fundamental, but often unstated, assumption of the gap approach 
that every statement of condition item that can re-price will do so to the full extent of any movement in market interest 
rates is taken into consideration in income simulation analysis. 

Accordingly,  income  simulation  analysis  captures  not  only  the  potential  of  assets  and  liabilities  to  mature  or 
re-price,  but  also  the  probability  that  they  will  do  so.  Moreover,  income  simulation  analysis  focuses  on  the  relative 
sensitivities of these balance sheet items and projects their behavior over an extended period of time in a motion picture 
rather than snapshot fashion. Finally, income simulation analysis permits management to assess the probable effects on 
balance sheet items not only of changes in market interest rates, but also of proposed strategies for responding to such 
changes.  We  and  many  other  institutions  rely  primarily  upon  income  simulation  analysis  in  measuring  and  managing 
exposure to interest rate risk. 

We have established guidelines for acceptable volatility of projected net interest income on the income simulation 
analysis and the guidelines are reviewed at least annually. As of December 31, 2020, in rising rate scenarios of +100, 
+200, +300 and +400 basis points, the guidelines established by management require that the net interest income not vary

by more than minus 30%, 30%, 30%, and 40%, respectively. Given the current low interest rate environment, no downward 
rate shifts were modeled in our income simulations.  At December 31, 2020, the income simulations show that a rate shift 
of +100, +200, +300 and +400 basis points in interest rates up will vary projected net interest income for the coming 
12-month period by +11.59%, +24.98%, +37.86%, and +50.41%, respectively. The basis point shift in interest rates is a 
hypothetical rate scenario used to calibrate risk and does not necessarily represent management’s current view of future 
market developments. We believe that we are properly positioned for a potential interest rate increase or decrease. 

All the measurements of risk described above are made based upon our business mix and interest rate exposures 
at  the  particular  point  in  time.  The  exposure  changes  continuously  as  a  result  of  our  ongoing  business  and  our  risk 
management initiatives. While management believes these measures provide a meaningful representation of our interest 
rate sensitivity, they do not necessarily take into account all business developments that have an effect on net income, such 
as changes in credit quality or the size and composition of the statement of condition. 

Our principal sources of liquidity and funding dividends from subsidiaries and borrowed funds, with such funds 
being used to finance our cash flow requirements. We closely monitor the dividend restrictions and availability from our 
Subsidiary Banks as disclosed in Note 20 to the Consolidated Financial Statements. At December 31, 2020, the aggregate 
amount legally available to be distributed to us from our Subsidiary Banks as dividends was approximately $948,000,000, 
assuming that each Subsidiary Bank continues to be classified as “well-capitalized” under the applicable regulations in 
effect  at  December 31,  2020.  The  restricted  capital  (capital  and  surplus)  of  our  Subsidiary  Banks  was  approximately 
$1,200,185,000  as  of  December 31,  2020.  The  undivided  profits  of  our  Subsidiary  Banks  were  approximately 
$1,351,802,000 as of December 31, 2020.  

At December 31, 2020, we had outstanding $436,327,000 in other borrowed funds and $134,642,000 in junior 
subordinated  deferrable  interest  debentures.  In  addition  to  borrowed  funds  and  dividends,  we  have  a  number  of  other 
available alternatives to finance the growth of our Subsidiary Banks as well as future growth and expansion. 

Capital 

We  maintain  an  adequate  level  of  capital  as  a  margin  of  safety  for  our  depositors  and  shareholders.  At 
December 31,  2020,  shareholders’  equity  was  $2,177,998,000  compared  to  $2,118,053,000  at  December 31,  2019,  an 
increase of $59,945,000, or 2.8%. Shareholders’ equity increased primarily due to the retention of earnings, offset by the 
payment  of  cash  dividends  to  shareholders  and  repurchases  of  our  common  stock  in  the  form  of  treasury  stock.  The 
accumulated other comprehensive income is not included in the calculation of regulatory capital ratios. 

During 1990, the FRB adopted a minimum leverage ratio of 3% for the most highly rated bank holding companies 
and  at  least  4%  to  5%  for  all  other  bank  holding  companies.  Our  leverage  ratio  (defined  as  shareholders’  equity  plus 
eligible trust preferred securities issued and outstanding less goodwill and certain other intangibles divided by average 
quarterly assets) was 14.92% at December 31, 2020 and 16.65% at December 31, 2019. The core deposit intangibles and 
goodwill of $282,532,000 as of December 31, 2020, are deducted from the sum of core capital elements when determining 
our capital ratios. 

The FRB has adopted risk-based capital guidelines which assign risk weightings to assets and off-balance sheet 
items. The guidelines also define and set minimum capital requirements (risk-based capital ratios). Under the final 1992 
rules, all banks are required to have Tier 1 capital of at least 4.0% of risk-weighted assets and total capital of 8.0% of 
risk-weighted assets. Tier 1 capital consists principally of shareholders’ equity plus trust preferred securities issued and 
outstanding  less  goodwill  and  certain  other  intangibles,  while  total  capital  consists  of  Tier 1  capital,  certain  debt 
instruments and a portion of the reserve for loan losses. In order to be deemed well-capitalized pursuant to the regulations, 
an institution must have a total risk-weighted capital ratio of 10%, a Tier 1 risk-weighted ratio of 8% and a Tier 1 leverage 
ratio of 5%. We had risk-weighted Tier 1 capital ratios of 20.25% and 19.80% and risk weighted total capital ratios of 
21.40%  and  20.46%  as  of  December 31,  2020  and  2019,  respectively,  which  are  well  above  the  minimum  regulatory 
requirements and exceed the well-capitalized ratios (see Note 20 to Notes to Consolidated Financial Statements). 

In July 2013, the Federal Deposit Insurance Corporation (“FDIC”) and other regulatory bodies established a new, 
comprehensive capital framework for U.S. banking organizations, consisting of minimum requirements that increase both 

20 

the quantity and quality of capital held by banking organizations. The final rules are a result of the implementation of the 
BASEL  III  capital  reforms  and  various  Dodd-Frank  related  capital  provisions.  Consistent  with  the  Basel  international 
framework, the rules include a minimum ratio of Common Equity Tier 1 (“CET1”) to risk-weighted assets of 4.5% and a 
CET1 capital conservation buffer of 2.5% of risk-weighted assets.  The capital conservation buffer began phasing-in on 
January 1, 2016 at .625% and increased each year until January 1, 2019, when we were required to have a 2.5% capital 
conservation buffer, effectively resulting in a minimum ratio of CET1 capital to risk-weighted assets of at least 7% upon 
full implementation. The rules also raised the minimum ratio of Tier 1 capital to risk-weighted assets from 4% to 6% and 
include a minimum leverage ratio of 4% for all banking organizations. Regarding the quality of capital, the rules emphasize 
CET1  capital  and  implements  strict  eligibility  criteria  for  regulatory  capital  instruments.  The  rules  also  improve  the 
methodology for calculating risk-weighted assets to enhance risk sensitivity. The rules were subject to a four-year phase 
in period for mandatory compliance and we were required to begin to phase in the rules beginning on January 1, 2015.  
We believe that as of December 31, 2020, we meet all fully phased-in capital adequacy requirements. 

On November 21, 2017, the OCC, the Federal Reserve and the FDIC finalized a proposed rule that extends the 
current treatment under the regulatory capital rules for certain regulatory capital deductions and risk weights and certain 
minority interest requirements, as they apply to banking organizations that are not subject to the advanced approaches 
capital rules.  Effective January 1, 2018, the rule also pauses the full transition to the Basel III treatment of mortgage 
servicing assets, certain deferred tax assets, investments in the capital of unconsolidated financial institutions and minority 
interests.  The agencies are also considering whether to make adjustments to the capital rules in response to CECL (the 
FASB Standard relating to current expected credit loss) and its potential impact on regulatory capital. 

On December 7, 2017, the Basel Committee on Banking Supervision unveiled the latest round of its regulatory 
capital framework, commonly called “Basel IV.”  The framework makes changes to the capital framework first introduced 
as “Basel III” in 2010.  The committee targeted 2022-2027 as the timeframe for implementation by regulators in individual 
countries, including the U.S. federal bank regulatory agencies (after notice and comment). 

Junior Subordinated Deferrable Interest Debentures 

We have formed five statutory business trusts under the laws of the State of Delaware, for the purpose of issuing 
trust preferred securities. These statutory business trusts (the “Trusts”) have each issued Capital and Common Securities 
and invested the proceeds thereof in an equivalent amount of junior subordinated debentures (the “Debentures”) that we 
issued.  As  of  December 31,  2020  and  December 31,  2019,  the  principal  amount  of  debentures  outstanding  totaled 
$134,642,000.  

The Debentures are subordinated and junior in right of payment to all of our present and future senior indebtedness 
(as defined in the respective indentures), and are pari passu with one another. The interest rate payable on, and the payment 
terms of the Debentures are the same as the distribution rate and payment terms of the respective issues of Capital and 
Common Securities issued by the Trusts. We have fully and unconditionally guaranteed the obligations of each of the 
Trusts with respect to the Capital and Common Securities. We have the right, unless an Event of Default (as defined in the 
Indentures) has occurred and is continuing, to defer payment of interest on the Debentures for up to twenty consecutive 
quarterly periods on Trusts VIII, IX, X, XI and XII. If interest payments on any of the Debentures are deferred, distributions 
on both the Capital and Common Securities related to that Debenture would also be deferred. The redemption prior to 
maturity of any of the Debentures may require the prior approval of the Federal Reserve and/or other regulatory bodies. 

For financial reporting purposes, the Trusts are treated as investments and not consolidated in the consolidated 
financial  statements. Although  the  Capital  Securities  issued  by  each of  the Trusts  are  not  included  as  a  component  of 
shareholders’ equity on the consolidated statement of condition, the Capital Securities are treated as capital for regulatory 
purposes. Specifically, under applicable regulatory guidelines, the Capital Securities issued by the Trusts qualify as Tier 1 
capital up to a maximum of 25% of Tier 1 capital on an  aggregate basis. Any amount that exceeds the 25% threshold 
would  qualify  as  Tier 2  capital.  At  December 31,  2020  and  December 31,  2019,  the  total  $134,642,000  of  the  Capital 
Securities outstanding qualified as Tier 1 capital.

Critical Accounting Policies 

We have established various accounting policies which govern the application of accounting principles in the 
preparation of our consolidated financial statements. The significant accounting policies are described in the Notes to the 
Consolidated Financial Statements. Certain accounting policies involve significant subjective judgments and assumptions

by management which have a material impact on the carrying value of certain assets and liabilities; management considers 
such accounting policies to be critical accounting policies. 

We consider our estimated ACL as a policy critical to the sound operations of our Subsidiary Banks. We adopted 
the provisions of Accounting Standards Update No. 2016-13 to ASC 326, “Financial Instruments – Credit Losses,” on 
January 1, 2020.  ASU 2016-13 replaces the long-standing incurred loss model with an expected credit loss model that 
recognizes credit losses over the life of a financial asset.  Expected credit losses capture historical information, current 
conditions, and reasonable and supportable forecasts of future conditions.  The ACL is deducted from the amortized cost 
of an instrument to present the net amount expected to be collected on the financial asset.  Our ACL primarily consists of 
the aggregate ACL estimates of our Subsidiary Banks. The estimates are established through charges to operations in the 
form of charges to provisions for credit loss expense.  Loan losses or recoveries are charged or credited directly to the 
ACL.  The  ACL  of  each  Subsidiary  Bank  is  maintained  at  a  level  considered  appropriate  by  management,  based  on 
estimated  current  expected  credit  losses  in  the  current  loan  portfolio,  including  information  about  past  events,  current 
conditions and reasonable and supportable forecasts.  

The estimation of the ACL is based on a loss-rate methodology that measures lifetime losses on loan pools that 
have similar risk characteristics. Loans that do not have similar risk characteristics are evaluated on an individual basis. 
The  segmentation  of  the  loan  portfolio  into  pools  requires  a  balancing  process  between  capturing  similar  risk 
characteristics and containing sufficient loss history to provide meaningful results.  Our segmentation starts at the general 
loan category with further sub-segmentation based on collateral types that may be of meaningful size and/or may contain 
sufficient differences in risk characteristics based on management’s judgement that would warrant further segmentation. 
The general loan categories along with primary risk characteristics used in our calculation are as follows: 

Commercial and industrial loans. This category includes loans extended to a diverse array of businesses for working 
capital  or  equipment  purchases.  These  loans  are  mostly  secured  by  the  collateral  pledged  by  the  borrower  that  is 
directly related to the business activities of the company such as equipment, accounts receivable and inventory. The 
borrower’s abilities to generate revenues from equipment purchases, collect accounts receivable, and to turn inventory 
into sales are risk factors in the repayment of the loan. A small portion of this loan category is related to loans secured 
by oil & gas production and loans secured by aircraft.  

Construction and land development loans. This category includes the development of land from unimproved land to 
lot development for both residential and commercial use and vertical construction across residential and commercial 
real estate classes. These loans carry risk of repayment when projects incur cost overruns, have an increase in the 
price of construction materials, encounter zoning, entitlement and environmental issues, or encounter other factors 
that may affect the completion of a project on time and on budget. Additionally, repayment risk may be negatively 
impacted when  the  market  experiences  a deterioration  in the value of  real  estate.  Risks  specifically  related  to 1-4 
family development loans also include mortgage rate risk and the practice by the mortgage industry of more restrictive 
underwriting standards, which inhibits the buyer from obtaining long term financing creating excessive housing and 
lot inventory in the market. 

Commercial  real  estate  loans.  This  category  includes  loans  secured  by  farmland,  multifamily  properties,  owner 
occupied  commercial  properties,  and  non-owner  occupied  commercial  properties.    Owner  occupied  commercial 
properties include warehouses often along the border for import/export operations, office space where the borrower 
is the primary tenant, restaurants and other single-tenant retail. Non-owner occupied commercial properties include 
hotels, retail centers, office and professional buildings, and leased warehouses. These loans carry risk of repayment 
when market values deteriorate, the business experiences turnover in key management, the business has an inability 
to attract or keep occupancy levels stable, or when the market experiences an exit of a specific business type that is 
significant to the local economy, such as a manufacturing plant. 

1-4 family mortgages. This category includes both first and second lien mortgages for the purpose of home purchases 
or refinancing of existing mortgage loans. A small portion of this loan category is related to home equity lines of 
credits,  lots  purchases,  and  home  construction.    Loan  repayments  may  be  affected  by  unemployment  or 
underemployment and deteriorating market values of real estate. 

23 

  
 
Consumer loans. This category includes deposit secured, vehicle secured, and unsecured loans, including overdrafts, 
made to individuals. Repayment is primarily affected by unemployment or underemployment. 

The  loan  pools  are  further  broken  down  using  a  risk-based  segmentation  based  on  internal  classifications  for 
commercial loans and past due status for consumer mortgage loans.  Non-mortgage consumer loans are evaluated as one 
segment.  On a weekly basis, commercial loan past due reports are reviewed by the credit quality committee to determine 
if a loan has any potential problems and if a loan should be placed on our internal Watch List report. Additionally, our 
credit department reviews the majority of our loans for proper internal classification purposes regardless of whether they 
are past due and segregates any loans with potential problems for further review. The credit department will discuss the 
potential problem loans with the servicing loan officers to determine any relevant issues that were not discovered in the 
evaluation. Also, an analysis of loans that is provided through examinations by regulatory authorities is considered in the 
review process. After the above analysis is completed, we will determine if a loan should be placed on an internal Watch 
List report because of issues related to the analysis of the credit, credit documents, collateral and/or payment history. 

Our internal Watch List report is segregated into the following categories: (i) Pass, (ii) Economic Monitoring, 
(iii) Special Review, (iv) Watch List—Pass, or (v) Watch List—Substandard, and (vi) Watch List—Doubtful.  The loans 
placed in the Special Review category and lower rated credits reflect our opinion that the loans reflect potential weakness 
which require monitoring on a more frequent basis. Credits in those categories are reviewed and discussed on a regular 
basis, no less frequently than quarterly, with the credit department and the lending staff to determine if a change in category 
is warranted. The loans placed in the Watch List—Pass category and lower rated credits reflect our opinion that the credit 
contains weaknesses which represent a greater degree of risk, which warrant “extra attention.” Credits in this category are 
reviewed and discussed on a regular basis with the credit department and the lending staff to determine if a change in 
category  is  warranted.  The  loans  placed  in  the  Watch  List—Substandard  category  are  considered  to  be  potentially 
inadequately protected by the current sound worth and debt service capacity of the borrower or of any pledged collateral. 
These  credit  obligations,  even  if  apparently  protected  by  collateral  value,  have  shown  defined  weaknesses  related  to 
adverse financial, managerial, economic, market or political conditions which may jeopardize repayment of principal and 
interest. Furthermore, there is the possibility that we may sustain some future loss if such weaknesses are not corrected. 
The loans placed in the Watch List—Doubtful category have shown defined weaknesses and it is likely, based on current 
information and events, that we will be unable to collect all principal and/or interest amounts contractually due.  Watch 
List—Doubtful loans are placed on non-accrual when they are moved to that category.   

For the purposes of the ACL, in order to maintain segments with sufficient history for meaningful results, the 
credits in the Pass and Economic Monitoring categories are aggregated, the credits in the Special Review and Watch List—
Pass credits are aggregated, and the credits in the Watch List—Substandard category remain in their own segment.  For 
loans that are classified as Watch List—Doubtful, management evaluates these credits in accordance with ASC 310-10, 
“Receivables,” and, if deemed necessary, a specific reserve is allocated to the loan. The specific reserve allocated under 
ASC 310-10, is based on (i) the present value of expected future cash flows discounted at the loan’s effective interest rate; 
(ii) the loan’s observable market price; or (iii) net realizable value of the fair value of the collateral if the loan is collateral 
dependent. Substantially all of our loans evaluated as Watch List—Doubtful under ASC 310-10 are measured using the 
fair value of collateral method. In rare cases, we may use other methods to determine the specific reserve of a loan under 
ASC 310-10 if such loan is not collateral dependent. 

Within each  collectively  evaluated pool, the  robustness of  the  lifetime historical  loss-rate  is  evaluated  and,  if 
needed, is supplemented with peer loss rates through a model risk adjustment.  Certain qualitative loss factors are then 
evaluated to incorporate management’s two-year reasonable and supportable forecast period followed by a reversion to 
the pool’s average lifetime loss-rate. Those qualitative loss factors are: (i) trends in portfolio volume and composition, 
(ii) volume and trends in classified loans, delinquencies, non-accruals and TDR’s, (iii) concentration risk, (iv) trends in 
underlying collateral value, (v) changes in policies, procedures, and strategies, and (vi) economic conditions.  Qualitative 
factors also include potential losses stemming from operational risk factors arising from fraud, natural disasters, pandemics 
and geopolitical events.  Should any of the factors considered by management in evaluating the adequacy of the ACL 
change, our estimate could also change, which could affect the level of future credit loss expense. 

We have elected to not measure an ACL for accrued interest receivable given our timely approach in identifying 
and writing off uncollectible accrued interest.  An ACL for off-balance sheet exposure is derived from a projected usage 

24 

 
rate of any unfunded commitment multiplied by the historical  loss rate, plus model risk adjustment, if any, of the on-
balance sheet loan pools. 

Our management continually reviews the ACL of the Subsidiary Banks using the amounts determined from the 
estimates established on specific doubtful loans, the estimate established on quantitative historical loss percentages, and 
the  estimate  based  on  qualitative  current  conditions  and  reasonable  and  supportable  two-year  forecasted  data.  Our 
methodology reverts to the average lifetime loss-rate beyond the forecast period when we can no longer develop reasonable 
and supportable forecasts.  Should any of the factors considered by management in evaluating the adequacy of the estimate 
for current expected credit losses change, our estimate of current expected credit losses could also change, which could 
affect the level of future credit loss expense. While the calculation of our ACL utilizes management’s best judgment and 
all information reasonably available, the adequacy of the ACL is dependent on a variety of factors beyond our control, 
including, among other things, the performance of the entire loan portfolio, the economy, government actions, changes in 
interest rates and the view of regulatory authorities towards loan classifications.

Stock Repurchase Program 

In  April 2009,  the  Board  of  Directors  re-established  a  formal  stock  repurchase  program  that  authorized  the 
repurchase of up to $40 million of common stock within the following 12 months.  Annually since then, including on 
March 12, 2020, the Board of Directors extended the repurchase program and for the second year authorized an increase 
to purchase up to $50 million of common stock during the 12 month period commencing on March 16, 2020 (previous 
annual stock repurchase programs began on April 9). Shares of common stock may be purchased from time to time on the 
open market or through privately negotiated transactions. Shares purchased under this program will be held in treasury for 
reissue for various corporate purposes, including employee compensation plans. During the fourth quarter of 2020, the 
Board of Directors adopted a Rule 10b5-1 trading plan, and intends to adopt additional Rule 10b5-1 trading plans, that 
will allow us to purchase shares of our common stock during certain trading blackout periods when we ordinarily would 
not be in the market due to trading restrictions in our insider trading policy. During the term of a Rule 10b5-1 trading plan, 
purchases of common stock are automatic to the extent the conditions of the plan’s trading instructions are met. Shares 
purchased under the Rule 10b5-1 trading plan will be held in treasury for reissue for various corporate purposes, including 
employee stock compensation plans. As of February 22, 2021, a total of 12,267,531 shares had been repurchased under all 
programs at a cost of $357,059,000. We are not obligated to purchase shares under our stock repurchase program outside 
of its Rule 10b5-1 trading plan. 

Except for repurchases in connection with the administration of an employee benefit plan in the ordinary course 
of business and consistent with past practices, common stock repurchases are only conducted under publicly announced 
repurchase programs approved by the Board of Directors. The following table includes information about common stock 
share repurchases for the quarter ended December 31, 2020.

Report of Independent Registered Public Accounting Firm 

Shareholders and the Board of Directors 
International Bancshares Corporation 

Opinion on the Financial Statements 
We have audited the accompanying consolidated statements of condition of International Bancshares 
Corporation and its subsidiaries (the Company) as of December 31, 2020 and 2019, the related 
consolidated statements of income, comprehensive income, shareholders' equity and cash flows for each 
of the three years in the period ended December 31, 2020, and the related notes to the consolidated 
financial statements (collectively, the financial statements). In our opinion, the financial statements 
present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 
2019, and the results of its operations and its cash flows for each of the three years in the period ended 
December 31, 2020, in conformity with accounting principles generally accepted in the United States of 
America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight 
Board (United States) (PCAOB), the Company’s internal control over financial reporting as of 
December 31, 2020, based on criteria established in Internal Control—Integrated Framework issued by 
the Committee of Sponsoring Organizations of the Treadway Commission in 2013, and our report dated 
February 25, 2021 expressed an unqualified opinion on the effectiveness of the Company’s internal 
control over financial reporting. 

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 U.S. federal securities laws and the applicable rules and regulations of the 
Securities and Exchange Commission and the PCAOB. 

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that 
we plan and perform the audits 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 
consolidated financial statements that was communicated or required to be communicated to the audit 
committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial 
statements and (2) involved our especially challenging, subjective, or complex judgments. The 
communication of critical audit matters 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. 

Allowance for Credit Losses 
As described in Note 4 of the consolidated financial statements, the company established an allowance 
for credit losses totaling $109,059,000 as of December 31, 2020. The allowance for credit losses is 
derived from a loss-rate methodology that measures lifetime losses on loan pools that have similar risk 
characteristics. Loans that do not have similar risk characteristics are evaluated on an individual basis. 
The segmentation of the loan portfolio into pools requires a balancing process between capturing similar 
risk characteristics and sufficient loss history to provide relevant results. Loan pools are further broken 
down using a risk-based segmentation based on internal classifications of credit quality. Within each loan 
pool, the lifetime historical loss-rate is evaluated and, if needed, is supplemented with peer loss rates 
through a model risk adjustment. Certain qualitative factors are applied at the loan pool level to 
incorporate management’s two-year forecast period followed by a reversion to the pool’s average lifetime 
loss-rate. Those qualitative factors include: (i) trends in portfolio volume and composition, (ii) volume and 
trends in classified loans, delinquencies, non-accruals and troubled debt restructurings (TDR’s), (iii) 
concentration risk, (iv) trends in underlying collateral value, (v) changes in policies, procedures, and 
strategies, (vi) economic conditions, and (vii) operational and other risk factors to capture potential losses 
arising from fraud, natural disasters, pandemics, and geopolitical events. 

We identified the qualitative factor component of the allowance for credit losses as a critical audit matter. 
Auditing management’s estimate of the qualitative factors required a high degree of auditor judgment due 
to the nature of the adjustments and the subjectivity in judgments applied by management in forming 
them.

Our audit procedures related to the Company’s qualitative factors included, the following, among others: 

  We obtained an understanding of the relevant controls related to the allowance for credit losses, 
including the qualitative factors, and tested such controls for design and operating effectiveness, 
including controls related to management’s review of the qualitative factors and approval of the 
allowance for credit losses calculation. 

  We evaluated the appropriateness and consistency of management’s methods and assumptions 

used to determine qualitative factors by (1) evaluating management’s identification and quantification 
of qualitative factors; (2) testing the completeness and accuracy of data and information used in 
calculating the components of the qualitative factors; (3) evaluating the reasonableness, directional 
consistency, and magnitude of the quantification of the qualitative factors; and (4) reviewing 
subsequent events and considering their impact on judgments applied in forming the qualitative factor 
component of the allowance for credit losses as of the consolidated balance sheet date. 

We have served as the Company’s auditor since 2007.

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 

Notes to Consolidated Financial Statements 

(1) Summary of Significant Accounting Policies 

Our accounting and reporting policies conform to U.S. generally accepted accounting principles (“GAAP”) and 

to general practices within the banking industry. The following is a description of the more significant of those policies. 

Consolidation and Basis of Presentation 

Our  consolidated  financial  statements  include  the  accounts  of  the  International  Bancshares  Corporation,  its 
wholly-owned  Subsidiary  Banks  and  its  wholly-owned  non-bank  subsidiaries,  IBC  Trading  Company,  Premier  Tierra 
Holdings, Inc., IBC Charitable and Community Development Corporation, and IBC Capital Corporation.  All significant 
inter-company balances and transactions have been eliminated in consolidation. 

We, through our Subsidiary Banks, are primarily engaged in the business of banking, including the acceptance of 
checking and savings deposits and the making of commercial, real estate, personal, home improvement, automobile and 
other  installment  and  term  loans.  Our  primary  markets  are  north,  south,  central,  and  southeast  Texas  and  the  state  of 
Oklahoma. Each of our Subsidiary Banks is very active in facilitating international trade along the United States border 
with Mexico and elsewhere. Although our loan portfolio is diversified, the ability of our debtors to honor their contracts 
is primarily dependent upon the economic conditions in our trade area. In addition, the investment portfolio is directly 
impacted by fluctuations in market interest rates. We are subject to the regulations of certain federal agencies as well as 
the Texas Department of Banking and the Oklahoma Department of Banking and undergo periodic examinations by those 
regulatory authorities. Such agencies may require certain standards or impose certain limitations based on their judgments 
or changes in law and regulations. 

We  own  one  insurance-related  subsidiary,  IBC  Insurance  Agency, Inc.,  a  wholly  owned  subsidiary  of  our 
Subsidiary  Bank,  International  Bank  of  Commerce,  Laredo.  The  insurance-related  subsidiary  does  not  conduct 
underwriting activities.  

The  preparation  of  the  consolidated  financial  statements  in  conformity  with  accounting  principles  generally 
accepted in the United States of America requires management to make estimates and assumptions that affect the reported 
amounts of assets and liabilities as of the dates of the statement of condition and income and expenses for the periods. 
Actual  results  could  differ  significantly  from  those  estimates.  Material  estimates  that  are  particularly  susceptible  to 
significant changes in the near-term relate to the determination of ACL. 

Subsequent Events 

We have evaluated all events or transactions that occurred through the date we issued these financial statements. 

During this period, we did not have any material recognizable or non-recognizable subsequent events. 

Investment Securities 

We  classify  debt  securities  into  one  of  these  categories:  held-to-maturity,  available-for-sale,  or  trading.  Such 
classifications are reassessed for appropriate classification at each reporting date. Securities that are intended and expected 
to  be  held  until  maturity  are  classified  as  “held-to-maturity”  and  are  carried  at  amortized  cost  for  financial  statement 
reporting. Securities that are not positively expected to be held until maturity, but are intended to be held for an indefinite 
period of time are classified as “available-for-sale” or “trading” and are carried at their fair value. Unrealized holding gains 
and losses are included in net income for those securities classified as “trading”, while unrealized holding gains and losses 
related to those securities classified as “available-for-sale” are excluded from net income and reported net of tax as other 
comprehensive income and in shareholders’ equity as accumulated other comprehensive income (loss) until realized. In 
accordance  with  ASU  2016-13,  which  we  adopted  on  January 1,  2020,  available-for-sale  and  held-to-maturity  debt 
securities  in  an  unrealized  loss  position  must  be  evaluated  for  the  underlying  cause  of  the  loss.    In  the  event  that  the 
deterioration  in  value  is  attributable  to  credit  related  reasons,  then  the  amount  of  credit-related  impairment  would  be 
recorded as a charge to our ACL with subsequent changes in the amount of impairment, up or down, also recorded through 
our ACL.  The exception to this process will occur if we intend to sell an impaired available-for-sale debt security or if we 

38 

 
 
 
INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 

Notes to Consolidated Financial Statements (Continued) 

will more likely than not be required to sell a credit impaired available-for-sale debt security prior to the value recovering 
to the security’s amortized cost.  In those situations, the entire credit-related impairment amount would be required to be 
recognized  in  earnings.    We  have  evaluated  the  debt  securities  classified  as  available-for-sale  and  held-to-maturity  at 
December 31, 2020 and have determined that no debt securities in an unrealized loss position are arising from credit related 
reasons and have therefore not recorded any allowances for debt securities in our ACL for the period.  Unrealized gains 
and losses related to equity securities with readily determinable fair values are included in net income. We did not maintain 
any trading securities during the three-year period ended December 31, 2020.  

Mortgage-backed  securities  held  at  December 31,  2020  and  2019  represent  participating  interests  in  pools  of 
long-term first mortgage loans originated and serviced by  the issuers of the securities.  Mortgage-backed securities are 
either issued or guaranteed by the U.S. government or its agencies including Freddie Mac, Fannie Mae, Ginnie Mae or 
other  non-government  entities.  Investments  in  residential  mortgage-backed  securities  issued  by  Ginnie  Mae  are  fully 
guaranteed by the U. S. government. Investments in residential mortgage-backed securities issued by Freddie Mac and 
Fannie Mae are not fully guaranteed by the U.S. government; however, we believe that the quality of the bonds is similar 
to other AAA rated bonds with limited credit risk, particularly given the placement of Fannie Mae and Freddie Mac into 
conservatorship  by  the  federal  government  in  2008  and  because  securities  issued  by  others  that  are  collateralized  by 
residential  mortgage-backed  securities  issued  by  Fannie  Mae  or  Freddie  Mac  are  rated  consistently  as  AAA  rated 
securities. Market interest rate fluctuations can affect the prepayment speed of principal and the yield on the security. 

Premiums and discounts are amortized using the level yield or “interest method” over the terms of the securities. 
Declines in the fair value of held-to-maturity and available-for sale-securities below their cost that are deemed to be other 
than  temporary  are  reflected  in  earnings  as  realized  losses.  In  determining  whether  other-than-temporary  impairment 
exists, management considers many factors, including (i) the length of time and the extent to which the fair value has been 
less  than  cost,  (ii) the  financial  condition  and  near-term  prospects  of  the  issuer,  and  (iii) our  intent  to  hold  and  our 
determination of whether we will more likely than not be required to sell the security prior to a recovery in fair value. If 
we determine that (i) we intend to sell the security or (ii) it is more likely than not that we will be required to sell the 
security before it’s anticipated recovery, the other-than-temporary impairment that is recognized in earnings is equal to 
the difference between the fair value of the security and our amortized cost of the security. If we determine that we (i) do 
not intend to sell the security and (ii) we will not be more likely than not required to sell the security before it’s anticipated 
recovery, the other-than-temporary impairment is segregated into its two components (i) the amount of impairment related 
to credit loss and (ii) the amount of impairment related to other factors. The difference between the present value of the 
cash flows expected to be collected and the amortized cost is the credit loss recognized through earnings and an adjustment 
to the cost basis of the security. The amount of impairment related to other factors is included in other comprehensive 
income (loss). Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific 
identification method.  

Equity Securities 

Prior to January 1, 2018, equity securities with readily determinable fair values were included in available-for-
sale securities, with the unrealized gain or loss recorded as a component of other comprehensive income (loss).  Pursuant 
to the adoption of ASU 2016-02, equity securities with readily determinable fair values are a separate component of our 
balance sheet, with unrealized gains and losses recognized in net income.  Equity securities with readily determinable fair 
values at December 31, 2020 and December 31, 2019 consist primarily of Community Reinvestment Act funds. 

Provision and Allowance for Credit Losses 

We adopted the provisions of Accounting Standards Update No. 2016-13 to ASC 326, “Financial Instruments – 
Credit Losses,” on January 1, 2020.  ASU 2016-13 replaces the long-standing incurred loss model with an expected credit 
loss  model  that  recognizes  credit  losses  over  the  life  of  a  financial  asset.    Expected  credit  losses  capture  historical 
information, current conditions, and reasonable and supportable forecasts of future conditions.  The ACL is deducted from 
the amortized cost of an instrument to present the net amount expected to be collected on the financial asset.  Our ACL 
primarily consists of the aggregate ACL estimates of our Subsidiary Banks. The estimates are established through charges 
to operations in the form of charges to provisions for credit loss expense.  Loan losses or recoveries are charged or credited 
directly to the ACL. The ACL of each Subsidiary Bank is maintained at a level considered appropriate by management, 

39 

 
INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 

Notes to Consolidated Financial Statements (Continued) 

based on estimated current expected credit losses in the current loan portfolio, including information about past events, 
current conditions and reasonable and supportable forecasts.   

Our management continually reviews the ACL of the Subsidiary Banks using the amounts determined from the 
estimates established on specific doubtful loans, the estimate established on quantitative historical loss percentages, and 
the  estimate  based  on  qualitative  current  conditions  and  reasonable  and  supportable  two-year  forecasted  data.  Our 
methodology reverts to the average lifetime loss-rate beyond the forecast period when we can no longer develop reasonable 
and supportable forecasts.  Should any of the factors considered by management in evaluating the adequacy of the estimate 
for current expected credit losses change, our estimate of current expected credit losses could also change, which could 
affect the level of future credit loss expense. While the calculation of our ACL utilizes management’s best judgment and 
all information reasonably available, the adequacy of the ACL is dependent on a variety of factors beyond our control, 
including, among other things, the performance of the entire loan portfolio, the economy, government actions, changes in 
interest rates and the view of regulatory authorities towards loan classifications.  We believe that the allowance for probable 
loan losses is adequate.  

The Subsidiary Banks charge-off that portion of any loan which management considers to represent a loss as well 
as that portion of any other loan which is classified as a “loss” by bank examiners. Commercial, financial and agricultural 
or real estate loans are generally considered by management to represent a loss, in whole or part, (i) when an exposure 
beyond  any  collateral  coverage  is  apparent,  (ii) when  no  further  collection  of  the  portion  of  the  loan  so  exposed  is 
anticipated  based  on  actual  results,  (iii) when  the  credit  enhancements,  if  any,  are  not  adequate,  and  (iv) when  the 
borrower’s financial condition would indicate so. Generally, unsecured consumer loans are charged-off when 90 days past 
due. 

Loans 

Loans are reported at the principal balance outstanding, net of unearned discounts. Interest income on loans is 
reported on an accrual basis. Loan fees and costs associated with originating the loans are accreted or amortized over the 
life of the loan using the interest method. We originate mortgage loans that may subsequently be sold to an unaffiliated 
third party. The loans are not securitized and if sold, are sold without recourse. Loans held for sale are carried at cost and 
the principal amount outstanding is not significant to the consolidated financial statements. 

Doubtful Loans 

Doubtful loans are those loans where it is probable that all amounts due according to contractual terms of the loan 
agreement will not be collected. Doubtful loans are measured based on (1) the present value of expected future cash flows 
discounted at the loan’s effective interest rate; (2) the loan’s observable market price; or (3) the fair value of the collateral 
if the loan is collateral dependent. Substantially all our doubtful loans are measured at the fair value of the collateral. In 
limited  cases,  we  may  use  other  methods  to  determine  the  level  of  impairment  of  a  loan  if  such  loan  is  not  collateral 
dependent. 

40

Troubled Debt Restructured Loans 

Troubled debt restructured loans (“TDR”) are those loans where, for reasons related to a borrower’s difficulty to 
repay a loan, we grant a concession to the borrower that we would not normally consider in the normal course of business. 
In accordance with interagency guidance issued in March 2020, certain short-term deferrals are not considered troubled 
debt restructurings. The original terms of the loan are modified or restructured. The terms that may be modified include a 
reduction in the original stated interest rate, an extension of the original maturity of the loan, a renewal of the loan at an 
interest rate below current market rates, a reduction in the principal amount of debt outstanding, a reduction in accrued 
interest or deferral of interest payments. A loan classified as a TDR is classified as a doubtful loan and included in the 
doubtful loan totals. A TDR loan may be returned to accrual status when the loan is brought current, has performed in 
accordance  with  the  restructured  terms  for a  reasonable  period  of  time,  is  at  the  current  market  rate,  and  the  ultimate 
collectability of the outstanding principal and interest is no longer questionable, however, although those loans may be 
placed back on accrual status, they will continue to be classified as doubtful. Consistent with regulatory guidance, a TDR 
loan that is subsequently modified, but has shown sustained performance and classification as a TDR, will be removed 
from TDR status provided that the modified terms were market-based at the time of modification. 

Non-Accrual Loans 

The  non-accrual  loan  policy  of  our  Subsidiary  Banks  is  to  discontinue  the  accrual  of  interest  on  loans  when 
management determines that it is probable that future interest accruals will be un-collectible. As it relates to consumer 
loans, management charges-off those loans when the loan is contractually 90 days past due. Under special circumstances, 
a consumer or non-consumer loan may be more than 90 days delinquent as to interest or principal and not be placed on 
non-accrual status. This situation generally results when a Subsidiary Bank has a borrower who is experiencing financial 
difficulties, but not to the extent that requires a restructuring of indebtedness. The majority of this category is composed 
of loans that are considered to be adequately secured and/or for which there are expected future payments. When a loan is 
placed on non-accrual status, any interest accrued, not paid is reversed and charged to operations against interest income. 
As  it  relates  to  non-consumer  loans  that  are  not  90 days  past  due,  management  will  evaluate  each  of  these  loans  to 
determine if placing the loan on non-accrual status is warranted. Interest income on non-accrual loans is recognized only 
to  the  extent  payments  are  received  or  when,  in  management’s  opinion,  the  debtor’s  financial  condition  warrants 
reestablishment of interest accruals. 

Other Real Estate Owned and Repossessed Assets 

Other real estate owned is comprised of real estate acquired by foreclosure and deeds in lieu of foreclosure. Other 
real estate is carried at the lower of the recorded investment in the property or its fair value less estimated costs to sell such 
property (as determined by independent appraisal). Prior to foreclosure, the value of the underlying loan is written down 
to the fair value of the real estate to be acquired by a charge to the ACL, if necessary. Any subsequent write-downs are 
charged against other non-interest expense through a valuation allowance. Other real estate owned totaled approximately 
$60,487,300 and $71,103,000 at December 31, 2020 and 2019, respectively. Other real estate owned is included in other 
assets.  Repossessed assets consist primarily of non-real estate assets acquired by foreclosure.  Prior to foreclosure, the 
value of the underlying loan is written down to the fair value of the asset to be repossessed by a charge to the ACL, if 
necessary.    Repossessed  assets  are  included  in  other  assets  on  the  consolidated  financial  statements  and  totaled 
approximately $5,779,000 and $7,137,000 at December 31, 2020 and 2019, respectively. 

Bank Premises and Equipment 

Bank  premises  and  equipment  are  stated  at  cost  less  accumulated  depreciation.  Depreciation  is  computed  on 
straight-line and accelerated methods over the estimated useful lives of the assets. Repairs and maintenance are charged 
to operations as incurred and expenditures for renewals and betterments are capitalized.   We primarily own all the property 
we occupy, with the exception of certain branches operating in grocery store or retail shopping centers and certain ATM 
locations, which are all under operating leases as classified under guidance prior to the issuance of ASU 2016-02, “Leases.”  
We adopted the guidance in ASU 2016-02 on January 1, 2019 and recorded a right of use asset and a lease liability of 
approximately $6.4 million.  The right of use asset and lease liability are included in other assets and other liabilities, 
respectively, in our consolidated financial statements.

Other Investments 

Other investments include equity investments in non-financial companies, as well as equity securities with no 
readily determinable fair market value. Equity investments are accounted for using the equity method of accounting. Equity 
securities with no readily determinable fair value are accounted for using the cost method. 

 Revenue Recognition 

Since our revenue is primarily comprised of net interest income on financial assets and liabilities, which were 
excluded from the scope of the update, the remaining non-interest revenue streams were identified and then analyzed under 
the  provisions  of  the  update,  to:    (i) identify  the  contract,  (ii) identify  the  performance  obligation,  (iii)  determine  the 
transaction price, (iv) allocate the transaction price to the performance obligations, and (v) recognize revenue when the 
performance obligation was satisfied.  Our non-interest revenue contracts with customers are primarily short term and our 
performance obligation is satisfied at a single point in time, typically within a single period.  No changes to our existing 
methods for recognizing revenue were made as a result of the update. 

Income Taxes 

Deferred income tax assets and liabilities are determined using the asset and liability method. Under this method, 
the net deferred tax asset or liability is determined based on the tax effects of the differences between the book and tax 
basis of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. We 
file a consolidated federal income tax return with our subsidiaries. 

Recognition  of  deferred  tax  assets  is  based  on  management’s  assessment  that  the  benefit  related  to  certain 
temporary differences, tax operating loss carry forwards, and tax credits are more likely than not to be realized. A valuation 
allowance is recorded for the amount of the deferred tax items for which it is more likely than not that the tax benefits will 
not be realized. 

We evaluate uncertain tax positions at the end of each reporting period. We may recognize the tax benefit from 
an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the 
taxing authorities, based on the technical merits of the position. The tax benefit recognized in the financial statements from 
any such a position is measured based on the largest benefit that has a greater than fifty percent likelihood of being realized 
upon ultimate settlement. As of December 31, 2020 and 2019, respectively, after evaluating all uncertain tax positions, we 
have recorded no liability for unrecognized tax benefits at the end of the reporting period. We would recognize any interest 
accrued on unrecognized tax benefits as other interest expense and penalties as other non-interest expense. During the 
years ended December 31, 2020, 2019 and 2018, we recognized no interest expense or penalties related to uncertain tax 
positions. 

We file consolidated tax returns in the U.S. Federal jurisdiction and various state jurisdictions. We are no longer 

subject to U.S. federal or state income tax examinations by tax authorities for years before 2017. 

Stock Options 

Compensation expense for stock awards is based on the market price of the stock on the measurement date, which 
is generally the date of grant, and is recognized ratably over the service period of the award. The fair value of stock options 
granted  was  estimated  using  the  Black-Sholes-Merton  option-pricing  model.  This  model  was  developed  for  use  in 
estimating the fair value of publicly traded options that have no vesting restrictions and are fully transferable. Additionally, 
the model requires the input of highly subjective assumptions. Because our employee stock options have characteristics 
significantly different from those of publicly traded options, and because changes in the subjective input assumptions can 
materially affect the fair value estimate, in management’s opinion, the Black-Scholes-Merton option-pricing model does 
not necessarily provide a reliable single measure of the fair value of our stock options.

Net Income Per Share 

Basic  Earnings  Per  Share  (“EPS”)  is  calculated  by  dividing  net  income  by  the  weighted  average  number  of 
common  shares  outstanding.  The  computation  of  diluted  EPS  assumes  the  issuance  of  common  shares  for  all  dilutive 
potential common shares outstanding during the reporting period. The dilutive effect of stock options is considered in 
earnings per share calculations, if dilutive, using the treasury stock method. 

Goodwill and Identified Intangible Assets 

Goodwill represents the excess of costs over fair value of assets of businesses acquired. Goodwill is tested for 
impairment at least annually or on an interim basis if an event triggering impairment may have occurred. As of October 1, 
2020, after completing goodwill testing, we have determined that no goodwill impairment exists. 

Identified 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 identified intangible assets relate to core deposits and contract 
rights.  As  of  December 31,  2020,  we  have  determined  that  no  impairment  of  identified  intangibles  exists.  Identified 
intangible assets with definite useful lives are amortized on an accelerated basis over their estimated life. See Note 6—
Goodwill and Other Intangible Assets. 

Impairment of Long-Lived Assets 

Long-lived assets, such as property, plant and equipment, and purchased intangibles subject to amortization, are 
reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not 
be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying value of the asset 
to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying value of an asset 
exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying value of 
the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the statement of 
condition and reported at the lower of the carrying value or fair value less costs to sell, and are no longer depreciated. The 
assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset 
and liability sections of the statement of condition. 

Consolidated Statements of Cash Flows 

For purposes of the consolidated statements of cash flows, we consider all short-term investments with a maturity 
at date of purchase of three months or less to be cash equivalents. Also, we report transactions related to deposits and loans 
to customers on a net basis. 

Accounting for Transfers and Servicing of Financial Assets 

We  account  for  transfers  and  servicing  of  financial  assets  and  extinguishments  of  liabilities  based  on  the 
application of a financial-components approach that focuses on control. After a transfer of financial assets, we recognize 
the financial and servicing assets we control and liabilities we have incurred, derecognize financial assets when control 
has  been  surrendered  and  derecognize  liabilities  when  extinguished.  We  have  retained  mortgage  servicing  rights  in 
connection with the sale of mortgage loans. Because we may not initially identify loans as originated for resale, all loans 
are  initially  treated  as  held  for  investment.  The  value  of  the  mortgage  servicing  rights  are  reviewed  periodically  for 
impairment and are amortized in proportion to, and over the period of estimated net servicing income or net servicing 
losses. The value of the mortgage servicing rights is not significant to the consolidated statements of condition. 

Segments of an Enterprise and Related Information 

We  operate  as  one  segment.  The  operating  information  used  by  our  chief  executive  officer  for  purposes  of 
assessing performance and making operating decisions is the consolidated financial statements presented in this report.

We have five active operating subsidiaries, namely, the Subsidiary Banks. We apply the provisions of ASC Topic 280, 
“Segment Reporting,” in determining our reportable segments and related disclosures. 

Comprehensive Income (Loss) 

Comprehensive  income  (loss)  consists  of  net  income  and  other  comprehensive  income  (loss).  Other 

comprehensive income (loss) includes unrealized gains and losses on securities available for sale. 

Advertising 

Advertising costs are expensed as incurred. 

Reclassifications 

Certain amounts in the prior year’s presentations have been reclassified to conform to the current presentation. 

These reclassifications had no effect on previously reported net income or shareholders’ equity. 

New Accounting Standards 

   In February 2016, the FASB issued Accounting Standards Update No. 2016-02 to ASC 820, “Leases.”  The 
update amends existing standards for accounting for leases by lessees, with accounting for leases by lessors remaining 
mainly unchanged from current guidance.  The update requires that lessees recognize a lease liability and a right of use 
asset  for  all  leases  (with  the  exception  of  short-term  leases)  at  the  commencement  date  of  the  lease  and  disclose  key 
information about leasing arrangements.  The update is to be applied on a modified retrospective basis for leases existing 
at, or entered into after, the beginning of the earliest comparative period presented in the consolidated financial statements.  
The update is effective for interim and annual periods beginning after December 15, 2018.  In January 2018, the FASB 
issued a proposal that provides an additional transition method that would allow entities to not apply the guidance in the 
update in the comparative periods presented in the consolidated financial statements, but instead recognize a cumulative-
effect adjustment to the opening balance of retained earnings in the period of adoption.  On January 1, 2019, we adopted 
the provisions of ASU 2016-02, “Leases.”  As part of our business model, we primarily own all property we occupy, with 
the exception of certain branches operating in grocery stores or shopping centers and certain ATM locations that were 
classified as operating leases under previous guidance.    The adoption of the standard did not have a significant impact on 
our consolidated financial statements.  As of the date of adoption, we recorded a right of use asset and a lease liability of 
approximately $6.4 million.  The right of use asset and lease liability are included in other assets and other liabilities, 
respectively, on our consolidated statement of condition.  Amortization of the right of use asset for the twelve months 
ended December 31, 2020 and December 31, 2019 was approximately $1,357,000 and $1,019,000, respectively, and is 
included as a part of occupancy expense in our consolidated income statement. 

In June 2016, the FASB issued Accounting Standards Update No. 2016-13 to ASC 326, “Financial Instruments – 
Credit Losses.”  The update amends existing standards for accounting for credit losses for financial assets.  The update 
requires that the expected credit losses on the financial instruments held as of the end of the period being reported be 
measured based on historical experience, current conditions, and reasonable and supportable forecasts.  The update also 
expands the required disclosures related to significant estimates and judgements used in estimating credit losses, as well 
as  the  credit  quality  and  underwriting  standards  of  an  organization’s  financial  assets.    The  update  also  amended  the 
accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration.  
The impact of the adoption of the standard is to be recorded as a cumulative-effect adjustment to retained earnings as of 
the beginning of the first reporting period in which the guidance is adopted.  The accounting standard was effective for us 
on  January 1,  2020.    The  task  force  formed  last  year,  which  includes  key  members  of  the  teams  that  work  with  the 
calculation  of  the  allowance  for  probable  loan  losses  plus  members  representing  the  corporate  accounting  and  risk 
management areas, has worked with the implementation of the update and validation to complete our model/tool.  Based 
on the composition of the portfolio at December 31, 2019 and after finalizing the methodology, the adoption of the update 
increased our allowance for probable loan losses (referred to as the ACL under ASU 2016-13), by approximately 17.2%, 
resulting in a cumulative-effect adjustment to retained earnings of approximately $8.3 million, net of tax.  Please refer to

Note 4 – Allowance for Credit Losses and the Critical Accounting Policies discussion in Management’s Discussion and 
Analysis.   

In  January 2017,  the  FASB  issued  Accounting  Standards  Update  No. 2017-04  to  ASC  350,  “Intangibles – 
Goodwill and Other.”  The update amends existing guidance in evaluating goodwill for impairment.  The update requires 
that an entity perform its annual or interim goodwill test by comparing the fair value of a reporting unit with its carrying 
amount, with any impairment charges being recognized as the difference between the fair value and carrying value.  The 
update is intended to standardize the impairment test for all business entities and also reduce the complexity and cost of 
evaluating goodwill for impairment.  The update is effective for any annual or interim goodwill impairment tests in fiscal 
years beginning after December 15, 2019.  The adoption of the update is not expected to have a significant impact to our 
consolidated financial statements. 

In  March 2017,  the  FASB  issued  Accounting  Standards  Update  No. 2017-08  to  ASC  310,  “Receivables – 
Nonrefundable  Fees  and  Other  Costs.”    The  update  amends  existing  guidance  on  the  amortization  period  for  certain 
callable debt securities held at a premium.  The update shortens the amortization period of the premium to the earliest call 
date.  The update is effective for fiscal years beginning after December 15, 2018.  The update is to be applied on a modified 
retrospective  basis  through  a  cumulative-effect  adjustment  to  retained  earnings  as  of  the  beginning  of  the  period  of 
adoption.  The adoption of the update did not have a significant impact to our consolidated financial statements. 

In February 2018, the FASB issued Accounting Standards Update No. 2018-02 to ASC 220, “Income Statement – 
Reporting Comprehensive Income.”  The update amends current guidance surrounding the reclassification of certain tax 
effects from accumulated other comprehensive income.  The update is being issued as a result of the 2017 Tax Cuts and 
Jobs Act and the related impact to comprehensive income as a result of the application of current guidance with respect to 
changes  in  tax  rates.    Under  current  guidance,  entities  must  re-evaluate  the  carrying  value  of  deferred  tax  assets  and 
liabilities and adjust them for the tax effect of the rate change and record that change through earnings.  The result is that 
the tax effects for items that normally would only be recognized in comprehensive income will be recognized through 
earnings and results in stranded tax effects in accumulated other comprehensive income (loss) for the impact of the rate 
change.  The update will allow a reclassification from accumulated other comprehensive income (loss) to retained earnings 
for the stranded tax effects resulting from the 2017 Tax Cuts and Jobs Act.  The update is effective for all entities for fiscal 
years beginning after December 31, 2018.  We adopted the provisions of ASU 2018-02 to ASC 220 in the second quarter 
of 2018. We recorded a one-time reclassification of $5,997,000 between accumulated comprehensive income (loss) and 
retained earnings as a result of the adoption of the accounting standards update. 

In  August 2018,  the  FASB  issued  Accounting  Standards  Update  No. 2018-13  to  ASC  820,  “Fair  Value 
Measurement.”  The update amends the existing guidance surrounding the disclosure of certain fair value measurements.  
The  update  removes  certain disclosures  that  are  no  longer  considered  cost  beneficial, modifies  and, in  some  instances 
clarifies, the specific requirements of certain disclosures and adds disclosure requirements that are identified relevant.  The 
update is effective for fiscal years beginning after December 15, 2019.  The adoption of the update is not expected to have 
a significant impact on our consolidated financial statements. 

In December 2019, the FASB issued Accounting Standards Update No. 2019-12, to ASC 740, “Income Taxes.”  
The update amends existing guidance with the intention of simplifying the accounting for income taxes.  Specifically, the 
update  removes  some  exceptions  in  existing  guidance  around  intraperiod  tax  allocations,  recognition  of  deferred  tax 
liabilities for certain changes in investments in foreign subsidiaries and to the general methodology for calculating taxes 
on interim periods when year to date losses exceed the anticipated loss for the year.  Additionally, the update clarifies and 
provides more guidance with respect to the classification of franchise or similar taxes, requirements to evaluate when a 
step up in the tax basis of goodwill should be considered, eliminates the requirement that a consolidated entity allocate a 
portion of current and deferred tax expense to a legal entity that is not subject to tax, requires that an entity reflect the 
effect  of  changes  in  tax  laws  and  tax  rates  in  the  effective  tax  rate  computed  in  the  interim  period  that  includes  the 
enactment date and makes minor changes for taxes related to employee stock ownership plans and investments in qualified 
affordable housing projects accounted for using the equity method.  The update is effective for fiscal years beginning after 
December 15, 2020.  The adoption of the update is not expected to have a significant impact on our consolidated financial 
statements.

In March 2020, the FASB issued Accounting Standards Update No. 2020-04, “Reference Rate Reform (Topic 
848):    Facilitation  of  the  Effects  of  Reference  Rate  Reform  on  Financial  Reporting.”    The  update  provides  optional 
guidance for a limited period of time to ease the potential burden in accounting for and recognizing the effects of reference 
rate reform on financial reporting.  The practical expedients and exceptions in the update apply only to contracts, hedging 
relationships and other transactions affected by reference rate reform if certain criteria are met.  The update does 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.  The update was effective as of the date of issuance and can be 
applied  through December 31, 2022.   We have  not  adopted  the provisions of  the update  and  to  not anticipate  that the 
adoption of the update will have a significant impact on our consolidated financial statements.   

In January 20201, the FASB issued Accounting Standards Update No. 2021-01, “Reference Rate Reform (Topic 
848): Scope.”  The update clarifies the applicability of the practical expedients and exceptions issued in ASU 2020-04 to 
derivative instruments that use an interest rate for margining, discounting or contract price alignment that is modified as a 
result of reference rate reform.  The update is intended to capture the incremental consequences of the scope clarification 
and tailor the existing guidance to derivative instruments affected by the discounting transition.  The update was effective 
as of the date of issuance and can be applied through December 31, 2022.  We have not adopted the provisions of the 
update and to not anticipate that the adoption of the update will have a significant impact on our consolidated financial 
statements.        

(2) Investment Securities 

In accordance with ASU 2016-13, which we adopted on January 1, 2020, available-for-sale and held-to-maturity 
debt securities in an unrealized loss position must be evaluated for the underlying cause of the loss.  In the event that the 
deterioration  in  value  is  attributable  to  credit  related  reasons,  then  the  amount  of  credit-related  impairment  would  be 
recorded as a charge to our ACL with subsequent changes in the amount of impairment, up or down, also recorded through 
our ACL.  The exception to this process will occur if we intend to sell an impaired available-for-sale debt security or if we 
will more likely than not be required to sell a credit impaired available-for-sale debt security prior to the value recovering 
to the security’s amortized cost.  In those situations, the entire credit-related impairment amount would be required to be 
recognized  in  earnings.    We  have  evaluated  the  debt  securities  classified  as  available-for-sale  and  held-to-maturity  at 
December 31, 2020 and have determined that no debt securities in an unrealized loss position are arising from credit related 
reasons and have therefore not recorded any allowances for debt securities in our ACL for the period.  Unrealized gains 
and losses related to equity securities with readily determinable fair values are included in net income.

$2,714,301 of mortgage-backed securities issued by Fannie Mae and Freddie Mac  

Residential  mortgage-backed  securities  are  securities  issued  by  Freddie  Mac,  Fannie  Mae,  Ginnie  Mae  or 
non-government entities. Investments in residential mortgage-backed securities issued by Ginnie Mae are fully guaranteed 
by the U.S. government. Investments in mortgage-backed securities issued by Freddie Mac and Fannie Mae are not fully 
guaranteed by the U.S. government; however, we believe that the quality of the bonds is similar to other AAA rated bonds 
with  limited  credit  risk, particularly given  the  placement of Fannie  Mae  and Freddie  Mac  into  conservatorship by  the 
federal government in early September 2008 and because securities issued by others that are collateralized by residential 
mortgage-backed securities issued by Fannie Mae and Freddie Mac are rated consistently as AAA rated securities. 

The  amortized  cost  and  fair  value  of  available  for  sale  investment  securities  pledged  to  qualify  for  fiduciary 
powers,  to  secure  public  monies  as  required  by  law,  repurchase  agreements  and  short-term  fixed  borrowings  was 
$1,220,400,000 and $1,224,268,000, respectively, at December 31, 2020. 

Proceeds from the sale and call of securities available-for-sale were $42,350,000, $94,585,000 and $59,782,000 
during 2020, 2019 and 2018, respectively, which amounts included $0, $0 and $0 of mortgage-backed securities. Gross 
gains of $1,000, $3,000 and $3,000, and gross losses of $6,000, $15,000 and $144,000 were realized on the sales and calls 
in 2020, 2019 and 2018, respectively.

The unrealized losses on investments in residential mortgage-backed securities are primarily caused by changes 
in market interest rates. We have no intent to sell and more likely than not be required to sell before a market price recovery 
or maturity of the securities; therefore, it is our conclusion that the investments in residential mortgage-backed securities 
issued by Freddie Mac, Fannie Mae and Ginnie Mae are not considered other-than-temporarily impaired.  

Equity securities with readily determinable fair values consist primarily of Community Reinvestment Act funds. 
At  December 31,  2020  and  December 31,  2019,  the  balance  in  equity  securities  with  readily  determinable  fair  values 
recorded  at  fair  value  were  $6,202,000  and  $6,095,000,  respectively.  The  following  is  a  summary  of  unrealized  and 
realized gains and losses recognized in net income on equity securities during the twelve months ended December 31, 
2020, December  31, 2019 and December 31, 2018:

(4) Allowance for Credit Losses 

We adopted the provisions of ASU 2016-13 on January 1, 2020 on a modified retrospective basis.  Results and 
information regarding our ACL included in this Note are calculated and presented in  accordance with that accounting 
standards  update.    Results  and  information  prior  to  January 1,  2020  are  calculated  and  presented  in  accordance  with 
previously applicable U.S. GAAP.   

ASU 2016-13 replaces the long-standing incurred loss model with an expected credit loss model that recognizes 
credit losses over the life of a financial asset.  Expected credit losses capture historical information, current conditions, 
and  reasonable  and  supportable  forecasts  of  future  conditions.    The  ACL  is  deducted  from  the  amortized  cost  of  an 
instrument to present the net amount expected to be collected on the financial asset.  Our ACL primarily consists of the 
aggregate ACL estimates of our Subsidiary Banks. The estimates are established through charges to operations in the form 
of charges to provisions for credit loss expense.  Loan losses or recoveries are charged or credited directly to the ACL. 
The ACL of each Subsidiary Bank is maintained at a level considered appropriate by management, based on estimated 
current expected credit losses in the current loan portfolio, including information about past events, current conditions and 
reasonable and supportable forecasts.

Notes to Consolidated Financial Statements (Continued) 

The estimation of the ACL is based on a loss-rate methodology that measures lifetime losses on loan pools that 
have similar risk characteristics. Loans that do not have similar risk characteristics are evaluated on an individual basis. 
The  segmentation  of  the  loan  portfolio  into  pools  requires  a  balancing  process  between  capturing  similar  risk 
characteristics and containing sufficient loss history to provide meaningful results.  Our segmentation starts at the general 
loan category with further sub-segmentation based on collateral types that may be of meaningful size and/or may contain 
sufficient differences in risk characteristics based on management’s judgement that would warrant further segmentation. 
The general loan categories along with primary risk characteristics used in our calculation are as follows: 

Commercial and industrial loans. This category includes loans extended to a diverse array of businesses for working 
capital  or  equipment  purchases.  These  loans  are  mostly  secured  by  the  collateral  pledged  by  the  borrower  that  is 
directly related to the business activities of the company such as equipment, accounts receivable and inventory. The 
borrower’s abilities to generate revenues from equipment purchases, collect accounts receivable, and to turn inventory 
into sales are risk factors in the repayment of the loan. A small portion of this loan category is related to loans secured 
by oil & gas production and loans secured by aircraft.  

Construction and land development loans. This category includes the development of land from unimproved land to 
lot development for both residential and commercial use and vertical construction across residential and commercial 
real estate classes. These loans carry risk of repayment when projects incur cost overruns, have an increase in the 
price of construction materials, encounter zoning, entitlement and environmental issues, or encounter other factors 
that may affect the completion of a project on time and on budget. Additionally, repayment risk may be negatively 
impacted when  the  market  experiences  a deterioration  in the value of  real  estate.  Risks  specifically  related  to 1-4 
family development loans also include mortgage rate risk and the practice by the mortgage industry of more restrictive 
underwriting standards, which inhibits the buyer from obtaining long term financing creating excessive housing and 
lot inventory in the market. 

Commercial  real  estate  loans.  This  category  includes  loans  secured  by  farmland,  multifamily  properties,  owner 
occupied  commercial  properties,  and  non-owner  occupied  commercial  properties.    Owner  occupied  commercial 
properties include warehouses often along the border for import/export operations, office space where the borrower 
is the primary tenant, restaurants and other single-tenant retail. Non-owner occupied commercial properties include 
hotels, retail centers, office and professional buildings, and leased warehouses. These loans carry risk of repayment 
when market values deteriorate, the business experiences turnover in key management, the business has an inability 
to attract or keep occupancy levels stable, or when the market experiences an exit of a specific business type that is 
significant to the local economy, such as a manufacturing plant. 

1-4 family mortgages. This category includes both first and second lien mortgages for the purpose of home purchases 
or refinancing of existing mortgage loans. A small portion of this loan category is related to home equity lines of 
credits,  lots  purchases,  and  home  construction.    Loan  repayments  may  be  affected  by  unemployment  or 
underemployment and deteriorating market values of real estate. 

Consumer loans. This category includes deposit secured, vehicle secured, and unsecured loans, including overdrafts, 
made to individuals. Repayment is primarily affected by unemployment or underemployment. 

The  loan  pools  are  further  broken  down  using  a  risk-based  segmentation  based  on  internal  classifications  for 
commercial loans and past due status for consumer mortgage loans.  Non-mortgage consumer loans are evaluated as one 
segment.  On a weekly basis, commercial loan past due reports are reviewed by the credit quality committee to determine 
if a loan has any potential problems and if a loan should be placed on our internal Watch List report. Additionally, our 
credit department reviews the majority of our loans for proper internal classification purposes regardless of whether they 
are past due and segregates any loans with potential problems for further review. The credit department will discuss the 
potential problem loans with the servicing loan officers to determine any relevant issues that were not discovered in the 
evaluation. Also, an analysis of loans that is provided through examinations by regulatory authorities is considered in the 
review process. After the above analysis is completed, we will determine if a loan should be placed on an internal Watch 
List report because of issues related to the analysis of the credit, credit documents, collateral and/or payment history.

Notes to Consolidated Financial Statements (Continued) 

Our internal Watch List report is segregated into the following categories: (i) Pass, (ii) Economic Monitoring, 
(iii) Special Review, (iv) Watch List—Pass, or (v) Watch List—Substandard, and (vi) Watch List—Doubtful.  The loans 
placed in the Special Review category and lower rated credits reflect our opinion that the loans reflect potential weakness 
which require monitoring on a more frequent basis. Credits in those categories are reviewed and discussed on a regular 
basis, no less frequently than quarterly, with the credit department and the lending staff to determine if a change in category 
is warranted. The loans placed in the Watch List—Pass category and lower rated credits reflect our opinion that the credit 
contains weaknesses which represent a greater degree of risk, which warrant “extra attention.” Credits in this category are 
reviewed and discussed on a regular basis with the credit department and the lending staff to determine if a change in 
category  is  warranted.  The  loans  placed  in  the  Watch  List—Substandard  category  are  considered  to  be  potentially 
inadequately protected by the current sound worth and debt service capacity of the borrower or of any pledged collateral. 
These  credit  obligations,  even  if  apparently  protected  by  collateral  value,  have  shown  defined  weaknesses  related  to 
adverse financial, managerial, economic, market or political conditions which may jeopardize repayment of principal and 
interest. Furthermore, there is the possibility that we may sustain some future loss if such weaknesses are not corrected. 
The loans placed in the Watch List—Doubtful category have shown defined weaknesses and it is likely, based on current 
information and events, that we will be unable to collect all principal and/or interest amounts contractually due.  Watch 
List—Doubtful loans are placed on non-accrual when they are moved to that category.   

For the purposes of the ACL, in order to maintain segments with sufficient history for meaningful results, the 
credits in the Pass and Economic Monitoring categories are aggregated, the credits in the Special Review and Watch List—
Pass credits are aggregated, and the credits in the Watch List—Substandard category remain in their own segment.  For 
loans that are classified as Watch List—Doubtful, management evaluates these credits in accordance with ASC 310-10, 
“Receivables,” and, if deemed necessary, a specific reserve is allocated to the loan. The specific reserve allocated under 
ASC 310-10, is based on (i) the present value of expected future cash flows discounted at the loan’s effective interest rate; 
(ii) the loan’s observable market price; or (iii) net realizable value of the fair value of the collateral if the loan is collateral 
dependent. Substantially all of our loans evaluated as Watch List—Doubtful under ASC 310-10 are measured using the 
fair value of collateral method. In rare cases, we may use other methods to determine the specific reserve of a loan under 
ASC 310-10 if such loan is not collateral dependent.  

Within each  collectively  evaluated pool, the  robustness of  the  lifetime historical  loss-rate  is  evaluated  and,  if 
needed, is supplemented with peer loss rates through a model risk adjustment.  Certain qualitative loss factors are then 
evaluated to incorporate management’s two-year reasonable and supportable forecast period followed by a reversion to 
the pool’s average lifetime loss-rate. Those qualitative loss factors are: (i) trends in portfolio volume and composition, 
(ii) volume and trends in classified loans, delinquencies, non-accruals and TDR’s, (iii) concentration risk, (iv) trends in 
underlying collateral value, (v) changes in policies, procedures, and strategies, and (vi) economic conditions.  Qualitative 
factors also include potential losses stemming from operational risk factors arising from fraud, natural disasters, pandemics 
and geopolitical events.  Should any of the factors considered by management in evaluating the adequacy of the ACL 
change, our estimate could also change, which could affect the level of future credit loss expense. 

We have elected to not measure an ACL for accrued interest receivable given our timely approach in identifying 
and writing off uncollectible accrued interest.  An ACL for off-balance sheet exposure is derived from a projected usage 
rate of any unfunded commitment multiplied by the historical  loss rate, plus model risk adjustment, if any, of the on-
balance sheet loan pools. 

Our management continually reviews the ACL of the Subsidiary Banks using the amounts determined from the 
estimates established on specific doubtful loans, the estimate established on quantitative historical loss percentages, and 
the  estimate  based  on  qualitative  current  conditions  and  reasonable  and  supportable  two-year  forecasted  data.  Our 
methodology reverts to the average lifetime loss-rate beyond the forecast period when we can no longer develop reasonable 
and supportable forecasts.  Should any of the factors considered by management in evaluating the adequacy of the estimate 
for current expected credit losses change, our estimate of current expected credit losses could also change, which could 
affect the level of future credit loss expense. While the calculation of our ACL utilizes management’s best judgment and 
all information reasonably available, the adequacy of the ACL is dependent on a variety of factors beyond our control, 
including, among other things, the performance of the entire loan portfolio, the economy, government actions, changes in 
interest rates and the view of regulatory authorities towards loan classifications.

The allowance for credit and probable loan losses is a reserve established through a provision for probable loan 
losses charged to expense, which represents management’s best estimate of probable loan losses when evaluating loans 
(i) individually  or  (ii) collectively.  The  increase  in  credit  loss  expense  for  the  year  ended  December 31,  2020  can  be 
primarily attributed to the deteriorating economic conditions occurring in those periods as a result of COVID-19 and the 
impact of those conditions on certain segments of our ACL calculation for those periods.  We adopted the provisions of 
ASU 2016-13 on January 1, 2020, resulting in a transition from the long-standing incurred loss model to an expected credit 
loss model. The increase in provision for probable loan losses charged to expense and charge-offs charged to the allowance 
for probable loan losses for the year ended December 31, 2019 can be primarily attributed to a relationship that is secured

fourth quarter of 2018, triggered by significant fraud by a high level insider of the car dealership resulting in the dealerships

unexpectedly filing for bankruptcy and creating an exposure for potential loss since the operations of the dealerships were 
the source of repayment from the borrower.  The relationship further deteriorated in the first quarter of 2019 after the 
sponsor of the court approved debtor in possession plan discontinued its role in the process and thus did not fulfill its 
obligation to assume full responsibility of the accrued and unpaid interest.  Although the relationship is secured by real 
property  (the  dealerships’  real  estate),  the  real  property  has  specialized  use,  contributing  to  the  potential  exposure  for 
probable  loss.    During  the  first  quarter  of  2019,  in  light  of  the  circumstances  and  management’s  evaluation  of  the 
relationship, the decision was made to place the relationship on impaired, non-accrual status and place a specific reserve 
on the relationship in the amount of $9.5 million.  During the second quarter of 2019, management continued to evaluate 
the relationship and decided to foreclose on the underlying real estate collateral, resulting in a charge-off of approximately 
$9.5 million, reflected in the tables above as part of the Commercial and commercial real estate: farmland and commercial 
categories. The decrease in the provision for probable loan losses charged to expense for the years ended December 31, 
2018 can be attributed to a decrease in the historical loss experience in the commercial category of the calculation.  As 
discussed in prior periods, charge-offs increased from historical levels due to the deterioration of one relationship that was 
secured  by  multiple  pieces  of  transportation  equipment  beginning  in  the  fourth  quarter  of  2014.    We  use  a  three-year 
historical charge-off experience in the calculation, therefore, as those charge-offs were eliminated from the calculation, 
the  allowance  for  probable  loan  losses  (now  ACL)  was  impacted.    As  fluctuations  occur  in  historical  loss  factors, 
management evaluates the need to adjust the qualitative factors used in the calculation to properly reflect probable loan 
losses.

impairment and their related allowance, by loan class:

Loans accounted for on a non-accrual basis at December 31, 2020, 2019 and 2018 amounted to $19,822,000, 
$4,886,000 and $15,791,000, respectively.  The increase in non-accrual commercial loans at December 31, 2020 compared 
to the same period of 2019 can be attributed to a relationship secured by commercial property.  The decrease in non-accrual 
commercial loans at December 31, 2019 compared to the same period of 2018 can be attributed to a relationship secured 
by equipment and accounts receivable that has been upgraded to Watch-List Substandard.  The effect of such non-accrual 
loans reduced interest income by approximately $694,000, $340,000 and $1,119,000 for the years ended December 31, 
2020, 2019 and 2018, respectively. Amounts received on non-accruals are applied, for financial accounting purposes, first 
to principal and then to interest after all principal has been collected. Accruing loans contractually past due 90 days or 
more as to principal or interest payments at December 31, 2020, 2019 and 2018 amounted to approximately $8,238,000, 
$59,705,000 and $40,674,000, respectively.  The increase at December 31, 2019 can be attributed to a relationship that is 
secured by multiple pieces of real property on which car dealerships are operated.

Doubtful loans are those loans where it is probable that all amounts due according to contractual terms of the loan 
agreement will not be collected. We have identified these loans through our normal loan review procedures. Doubtful 
loans are measured based on (i) the present value of expected future cash flows discounted at the loan’s effective interest 
rate;  (ii) the  loan’s  observable  market  price;  or  (iii) the  fair  value  of  the  collateral  if  the  loan  is  collateral  dependent. 
Substantially all of our doubtful loans are measured at the fair value of the collateral. In limited cases, we may use other 
methods to determine the level of impairment of a loan if such loan is not collateral dependent.

We are actively working with our customers affected by the current economic crisis arising from COVID-19.  We 
have been offering and are prepared to continue to offer assistance in accordance with current regulatory guidance.  That 
includes continuously reaching out to our customers and, in some cases, offering short-term payment deferral plans.  In 
accordance with the Coronavirus Aid, Relief and Economic Security (“CARES”) Act or interagency regulatory guidance, 
these  short-term  deferrals  are  not  considered  troubled  debt  restructurings.    As  of  February 22,  2021,  approximately 
$1,011,570,000 in loans with some degree of payment deferrals were in our system.  Approximately 78% of the loans 
originally put into some sort of deferral program have resumed regular payments.  The end of the deferral period on loans 
that are in some sort of payment deferral program will be throughout the first and second quarters of 2021 and we anticipate 
that approximately 13% of the loans still in a payment deferral program will request some degree of additional relief.  The 
loans that may be requesting additional relief will include some customers in the industries that have been significantly 
impacted by the COVID-19 pandemic, including the hospitality sector, the oil and gas industry and retail developments.    

The CARES Act was signed into law on March 27, 2020.  It contains substantial tax and spending provisions 
intended to address the impact of the COVID-19 pandemic.  The CARES Act includes the Paycheck Protection Program

(“PPP”), originally a nearly $350 billion program designed to aid small businesses through federally guaranteed loans 
distributed through banks.  These loans were originally intended to support eight weeks of payroll and certain other costs 
to help those businesses remain viable and allow their employees to pay their bills.  Subsequently, on April 24, 2020, the 
Paycheck Protection Program and Health Care Enhancement Act (“CARES Part II”) was signed into law.  CARES Part II 
provided an additional funding of $320 billion for the PPP program.  Then, on June 5, 2020, the Paycheck Protection 
Program Flexibility Act (“PPPFA”) was signed into law.  The PPPFA, among other things, extended the period of time 
that businesses could spend PPP loan proceeds on payroll and other eligible costs from eight weeks to the earlier of 24 
weeks or December 31, 2020.  On December 27, 2020, the Economic Aid to Hard-Hit Small Businesses, Nonprofits and 
Venues Act (the “Economic Aid Act”) was enacted, which among other things, reauthorized lending under the PPP to 
first-time borrowers and for second draws by certain borrowers who have previously received PPP loans.  The Economic 
Aid Act made available an additional $147 billion for PPP loans requested by March 31, 2021.  We have been active 
participants  in  helping our  customers obtain  PPP  loans under  all  the  PPP  programs  and  as  of  February 22, 2021 have 
approximately 3,500 loans with an approximate value of $395,872,000 outstanding.  The PPP loans are fully guaranteed 
by the U.S. government through the SBA.     

The Subsidiary Banks charge-off that portion of any loan which management considers to represent a loss as well 
as that portion of any other loan which is classified as a “loss” by bank examiners.  Commercial and industrial or real 
estate loans are generally considered by management to represent a loss, in whole or part, when an exposure beyond any 
collateral coverage is apparent and when no further collection of the loss portion is anticipated based on the borrower’s 
financial condition and general economic conditions in the borrower’s industry. Generally, unsecured consumer loans are 
charged-off when 90 days past due. 

While management considers that it is generally able to identify borrowers with financial problems reasonably 
early and to monitor credit extended to such borrowers carefully, there is no precise method of predicting loan losses. The 
determination that a loan is likely to be uncollectible and that it should be wholly or partially charged-off as a loss is an 
exercise of judgment. Similarly, the determination of the adequacy of the ACL (formerly allowance for probable loan 
losses) can be made only on a subjective basis. It is the judgment of our management that the ACL at December 31, 2020 
and December 31, 2019, was adequate to absorb probable losses from loans in the portfolio at that date.

The decrease in commercial real estate:  other construction & land development loans past due 90 days or greater 
at December 31, 2020 compared to December 31, 2019 can be primarily attributed to a relationship secured by real estate 
on which children’s learning centers are operated.  Our internal classified report is segregated into the following categories: 
(i) “Special  Review  Credits,”  (ii) “Watch  List—Pass  Credits,”  or  (iii) “Watch  List—Substandard  Credits.”  The  loans 
placed in the “Special Review Credits” category reflect our opinion that the loans reflect potential weakness which require 
monitoring on a more frequent basis. The “Special Review Credits” are reviewed and discussed on a regular basis with 
the  credit department  and  the  lending  staff  to determine  if  a change  in category  is warranted. The  loans placed  in  the 
“Watch List—Pass Credits” category reflect our opinion that the credit contains weaknesses which represent a greater 
degree of risk, which warrant “extra attention.” The “Watch List—Pass Credits” are reviewed and discussed on a regular 
basis with the credit department and the lending staff to determine if a change in category is warranted. The loans placed 
in the “Watch List—Substandard Credits” classification are considered to be potentially inadequately protected by the 
current sound worth and debt service capacity of the borrower or of any pledged collateral. These credit obligations, even 
if  apparently  protected  by  collateral  value,  have  shown  defined  weaknesses  related  to  adverse  financial,  managerial, 
economic, market or political conditions which may jeopardize repayment of principal and interest. Furthermore, there is 
the possibility that we could sustain some future loss if such weaknesses are not corrected.

(10) Junior Subordinated Deferrable Interest Debentures 

We have formed five statutory business trusts under the laws of the State of Delaware for the purpose of issuing 
trust preferred securities. These statutory business trusts (the “Trusts”) have each issued Capital and Common Securities 
and invested the proceeds thereof in an equivalent amount of junior subordinated debentures (the “Debentures”) we issued. 
As of December 31, 2020 and December 31, 2019, the principal amount of debentures outstanding totaled $134,642,000.  

The Debentures are subordinated and junior in right of payment to all our present and future senior indebtedness 
(as defined in the respective indentures) and are pari passu with one another. The interest rate payable on, and the payment 
terms of the Debentures are the same as the distribution rate and payment terms of the respective issues of Capital and 
Common Securities issued by the Trusts. We have fully and unconditionally guaranteed the obligations of each of the 
Trusts with respect to the Capital and Common Securities. We have the right, unless an Event of Default (as defined in the 
Indentures) has occurred and is continuing, to defer payment of interest on the Debentures for up to twenty consecutive 
quarterly periods on Trusts VIII, IX, X, XI and XII. If interest payments on any of the Debentures are deferred, distributions 
on both the Capital and Common Securities related to that Debenture would also be deferred. The redemption prior to 
maturity of any of the Debentures may require the prior approval of the Federal Reserve and/or other regulatory bodies. 

For financial reporting purposes, the Trusts are treated as investments and not consolidated in the consolidated 
financial  statements. Although  the  Capital  Securities  issued  by  each of  the Trusts  are  not  included  as  a  component  of 
shareholders’ equity on the consolidated statement of condition, the Capital Securities are treated as capital for regulatory 
purposes. Specifically, under applicable regulatory guidelines, the Capital Securities issued by the Trusts qualify as Tier 1 
capital up to a maximum of 25% of Tier 1 capital on an  aggregate basis. Any amount that exceeds the 25% threshold 
would  qualify  as  Tier 2  capital.  At  December 31,  2020  and  December 31,  2019,  the  total  $134,642,000  of  the  Capital 
Securities outstanding qualified as Tier 1 capital.

(11) Earnings per Share (“EPS”) 

Basic EPS is calculated by dividing net income by the weighted average number of common shares outstanding. 
The  computation  of  diluted  EPS  assumes  the  issuance  of  common  shares  for  all  dilutive  potential  common  shares 
outstanding  during  the  reporting  period.  The  calculation  of  the  basic  EPS  and  the  diluted  EPS  for  the  years  ended 
December 31, 2020, 2019, and 2018 is set forth in the following table:

(12) Employees’ Profit Sharing Plan 

We  have  a  deferred  profit  sharing  plan  for  full-time  employees  with  a  minimum  of  one  year  of  continuous 
employment. Our annual contribution to the plan is based on a percentage, as determined by our Board of Directors, of 
income  before  income  taxes,  as  defined,  for  the  year.  Allocation  of  the  contribution  among  officers  and  employees’ 
accounts is based on length of service and amount of salary earned. Profit sharing costs of $4,000,000, $4,200,000 and 
$3,850,000 were charged to income for the years ended December 31, 2020, 2019, and 2018, respectively. 

(13) International Operations 

We provide international banking services for our customers through our Subsidiary Banks. Neither we nor our 
Subsidiary Banks have facilities located outside the United States. International operations are distinguished from domestic 
operations based upon the domicile of the customer. 

Because the resources we employ are common to both international and domestic operations, it is not practical to 

determine net income generated exclusively from international activities.

Plan (the “2012 Plan”). There are 800,000 shares available for stock option grants under the 2012 Plan. Under the 2012 
Plan, both qualified incentive stock options (“ISOs”) and non-qualified stock options (“NQSOs”) may be granted. Options 
granted  may  be  exercisable  for  a  period  of  up  to  10  years  from  the  date  of  grant,  excluding  ISOs  granted  to  10% 
shareholders, which may be exercisable for a period of up to only five years. As of December 31, 2020, 10,102 shares 
were available for future grants under the 2012 Plan.

The  fair  value  of  each  option  award  granted  under  the  plan  is  estimated  on  the  date  of  grant  using  a 
Black-Scholes-Merton option valuation model that uses the assumptions noted in the following table. Expected volatility 
is based on the historical volatility of the price of our stock. We use historical data to estimate the expected dividend yield 
and  employee  termination  rates  within  the  valuation  model.  The  expected  term  of  options  is  derived  from  historical 
exercise behavior. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield 
curve in effect at the time of grant.

 (16) Long Term Restricted Stock Units  

As a former participant in the Troubled Asset Relief Program Capital Purchase Program (the “CPP”) we were 
subject to certain compensation restrictions, including a prohibition on the payment or accrual of any bonuses to certain 
officers and employees except for awards of CPP-compliant long- term restricted stock and stock units. 

On  December 18,  2009,  our  board  of  directors  (the  “Board”)  adopted  the  2009  International  Bancshares 
Corporation Long-Term Restricted Stock Unit Plan (the “Plan”) to give us additional flexibility in the compensation of 
our officers, employees, consultants and advisors in compliance with all applicable laws and restrictions. 

The  Plan  authorizes  us  to  issue  Restricted  Stock  Units  (“RSUs”)  to  our  officers,  employees,  consultants  and 
advisors.  On December 18, 2009, pursuant to the Plan, the Board adopted resolutions creating the Long-Term Restricted 
Stock Unit Plan Committee to administer the Plan. RSUs issued under the Plan are not equity and are payable only in cash. 
The Plan provides for both the issuance of CPP-compliant long-term RSUs as well as RSUs that are not CPP-compliant.  
No grants have been made under the Plan since December 2012 and there are currently no outstanding grants under the 
Plan. The plan was terminated on August 6, 2019.  

(17) Commitments, Contingent Liabilities and Other Matters 

On  March 15,  2020,  the  FRB  announced  that  it  had  reduced  regulatory  reserve  requirements  to  zero  percent 
effective  on  March 26,  2020.    Cash  of  approximately  $125,764,000  December 31,  2019  was  maintained  to  satisfy 
regulatory reserve requirements. 

We are involved in various legal proceedings that are in various stages of litigation. We have determined, based 
on discussions with our counsel that any material loss in such actions, individually or in the aggregate, is remote or the 
damages sought, even if fully recovered, would not be considered material to our consolidated statements of condition and 
related  statements  of  income,  comprehensive  income,  shareholders’  equity  and  cash  flows.  However,  many  of  these 
matters are in various stages of proceedings and further developments could cause management to revise its assessment of 
these matters. 

(18) Transactions with Related Parties 

In  the  ordinary  course  of  business,  the  Subsidiary  Banks  make  loans  to  our  directors  and  executive  officers, 
including their affiliates, families and companies in which they are principal owners. In the opinion of management, these 
loans are made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for 
comparable transactions with other persons and do not involve more than normal risk of collectability or present other 
unfavorable features. The aggregate amounts receivable from such related parties amounted to approximately $30,398,000 
and $37,605,000 at December 31, 2020 and 2019, respectively. 

(19) Financial Instruments with Off-Statement of Condition Risk and Concentrations of Credit Risk 

In the normal course of business, the Subsidiary Banks are party to financial instruments with off-statement of 
condition risk to meet the financing needs of their customers. These financial instruments include commitments to their 
customers.  These  financial  instruments  involve,  to  varying  degrees,  elements  of  credit  risk  in  excess  of  the  amounts 
recognized  in the  consolidated  statement  of  condition.  The  contract  amounts  of  these  instruments  reflect  the  extent of 
involvement the Subsidiary Banks have in particular classes of financial instruments. At December 31, 2020, the following 
financial amounts of instruments, whose contract amounts represent credit risks, were outstanding:

Notes to Consolidated Financial Statements (Continued) 

We enter into a standby letter of credit to guarantee performance of a customer to a third party. These guarantees 
are primarily issued to support public and private borrowing arrangements. The credit risk involved is represented by the 
contractual amounts of those instruments. Under the standby letters of credit, we are required to make payments to the 
beneficiary of the letters of credit upon request by the beneficiary so long as all performance criteria have been met. At 
December 31, 2020, the maximum potential amount of future payments is approximately $118,381,000. At December 31, 
2020, the fair value of these guarantees is not significant. Unsecured letters of credit totaled approximately $39,487,000 
and $49,965,000 at December 31, 2020 and 2019, respectively. 

We enter into commercial letters of credit on behalf of our customers which authorize a third party to draw drafts 
upon us up to a stipulated amount and with specific terms and conditions. A commercial letter of credit is a conditional 
commitment on our part to provide payment on drafts drawn in accordance with the terms of the commercial letter of 
credit. 

The Subsidiary Banks’ exposure to credit loss in the event of nonperformance by the other party to the above 
financial instruments is represented by the contractual amounts of the instruments. The Subsidiary Banks use the same 
credit policies in making commitments and conditional obligations as they do for on-statement of condition instruments. 
The  Subsidiary  Banks  control  the  credit  risk  of  these  transactions  through  credit  approvals,  limits  and  monitoring 
procedures. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any 
condition established in the contract. Commitments generally have fixed expiration dates normally less than one year or 
other termination clauses and may require the payment of a fee. Since many of the commitments are expected to expire 
without  being  drawn  upon,  the  total  commitment  amounts  do  not  necessarily  represent  future  cash  requirements.  The 
Subsidiary Banks evaluate each customer’s credit-worthiness on a case-by-case basis. The amount of collateral obtained, 
if deemed necessary by the Subsidiary Banks upon extension of credit, is based on management’s credit evaluation of the 
customer.  Collateral  held  varies,  but  may  include  residential  and  commercial  real  estate,  bank  certificates  of  deposit, 
accounts receivable and inventory. 

The Subsidiary Banks make commercial, real estate and consumer loans to customers principally located in South, 
Central and Southeast Texas and the State of Oklahoma. Although the loan portfolio is diversified, a substantial portion 
of its debtors’ ability to honor their contracts is dependent upon the economic conditions in these areas, especially in the 
real estate and commercial business sectors. 

(20) Capital Requirements 

Bank regulatory agencies limit the amount of dividends, which the Subsidiary Banks can pay, without obtaining 
prior  approval  from  such  agencies.  At  December 31,  2020,  the  Subsidiary  Banks  could  pay  dividends  of  up  to 
$948,000,000  without  prior  regulatory  approval  and  without  adversely  affecting  their  “well-capitalized”  status  under 
regulatory  capital  rules  in  effect  at  December 31,  2020.  In  addition  to  legal  requirements,  regulatory  authorities  also 
consider the adequacy of the Subsidiary Banks’ total capital in relation to their deposits and other factors. These capital 
adequacy  considerations  also  limit  amounts  available for payment of dividends.  We historically have not  allowed any 
Subsidiary Bank to pay dividends in such a manner as to impair its capital adequacy. 

We and the Subsidiary Banks are subject to various regulatory capital requirements administered by the federal 
banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional 
discretionary actions by regulators that, if undertaken, could have a direct material effect on our consolidated financial 
statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, we must meet 
specific capital guidelines that involve quantitative measures of our assets, liabilities, and certain off-statement of condition 
items  as  calculated  under  regulatory  accounting  practices.  Our  capital  amounts  and  classification  are  also  subject  to 
qualitative judgments by the regulators about components, risk weightings, and other factors. 

Current  quantitative  measures  established  by  regulation  to  ensure  capital  adequacy  require  us  to  maintain 
minimum amounts and ratios (set forth in the table on the following page) of Total and Tier 1 capital to risk-weighted 
assets and of Tier 1 capital to average assets. Management  believes, as of December 31, 2020, that we met all capital 
adequacy requirements to which we are subject.

Notes to Consolidated Financial Statements (Continued) 

In July 2013, the FDIC and other regulatory bodies established a new, comprehensive capital framework for U.S. 
banking organizations, consisting of minimum requirements that increase both the quantity and quality of capital held by 
banking organizations. The final rules are a result of the implementation of the BASEL III capital reforms and various 
Dodd-Frank  related  capital  provisions.  Consistent  with  the  Basel  international  framework,  the  rules  include  a  new 
minimum ratio of Common Equity Tier 1 (“CET1”) to risk-weighted assets of 4.5% and a CET1 capital conservation 
buffer of 2.5% of risk-weighted assets.  The capital conservation buffer began phasing-in on January 1, 2016 at .625% and 
increased each year until January 1, 2019, when we were required to have a 2.5% capital conservation buffer, effectively 
resulting in a minimum ratio of CET1 capital to risk-weighted assets of at least 7% upon full implementation. The rules 
also raised the minimum ratio of Tier 1 capital to risk-weighted assets from 4% to 6% and include a minimum leverage 
ratio  of  4%  for  all  banking  organizations.  Regarding  the  quality  of  capital,  the  rules  emphasize  CET1  capital  and 
implements  strict  eligibility  criteria  for  regulatory  capital  instruments.  The  rules  also  improve  the  methodology  for 
calculating  risk-weighted  assets  to  enhance  risk  sensitivity.  The  rules  were  subject  to  a  four-year  phase-in  period  for 
mandatory compliance and we were required to begin to phase-in the new rules beginning on January 1, 2015.  We believe 
that as of December 31, 2020, we meet all fully phased-in capital adequacy requirements. 

On November 21, 2017, the OCC, the Federal Reserve and the FDIC finalized a proposed rule that extends the 
current treatment under the regulatory capital rules for certain regulatory capital deductions and risk weights and certain 
minority interest requirements, as they apply to banking organizations that are not subject to the advanced approaches 
capital rules.  Effective January 1, 2018, the rule also paused the full transition to the Basel III treatment of mortgage 
servicing assets, certain deferred tax assets, investments in the capital of unconsolidated financial institutions and minority 
interests.  The agencies are also considering whether to make adjustments to the capital rules in response to CECL (the 
FASB Standard relating to current expected credit loss) and its potential impact on regulatory capital. 

On December 7, 2017, the Basel Committee on Banking Supervision unveiled the latest round of its regulatory 
capital framework, commonly called “Basel IV.”  The framework makes changes to the capital framework first introduced 
as “Basel III” in 2010.  The committee targeted 2022-2027 as the timeframe for implementation by regulators in individual 
countries, including the U.S. federal bank regulatory agencies (after notice and comment). 

The aforementioned capital conservation buffer is designed to absorb losses during periods of economic stress. 
Banking institutions with a ratio of CET1 capital to risk-weighted assets above the minimum but below the conservation 
buffer will face constraints on dividends, equity repurchases and compensation based on the amount of the shortfall. 

As of December 31, 2019, our capital levels exceed all capital adequacy requirements under the Basel III Capital 
Rules as currently applicable to us. Based on the ratios presented below, capital levels as of December 31, 2020 exceed 
the minimum levels necessary to be considered “well-capitalized.”   

On  May 24,  2018,  the  EGRRCPA  was  enacted  and,  among  other  things,  it  includes  a  simplified  capital  rule 
change which effectively exempts banks with assets of less than $10 billion that exceed the “community bank leverage 
ratio,” from all risk-based capital requirements, including Basel III and its predecessors. The federal banking agencies 
must establish the “community bank leverage ratio” (a ratio of tangible equity to average consolidated assets) between 8% 
and 10% before community banks can begin to take advantage of this regulatory relief provision. Some of the Subsidiary 
Banks, with assets of less than $10 billion, may qualify for this exemption. Additionally, under the EGRRCPA, qualified 
bank holding companies with assets of up to $3 billion (currently $1 billion) will be eligible for the Federal Reserve’s 
Small Bank Holding Company Policy Statement, which eases limitations on the issuance of debt by holding companies. 
On August 28, 2018, the Federal Reserve issued an interim final rule expanding the applicability of its Small Bank Holding 
Company Policy Statement. While holding companies that meet the conditions of the policy statement are excluded from 
consolidated capital requirements, their depository institutions continue to be subject to minimum capital requirements. 
Finally, for banks that continue to be subject to the risk-based capital rules of Basel III (e.g., 150%), certain commercial 
real estate loans that were formally classified as high volatility commercial real estate 31 (“HVCRE”) will not be subject 
to heightened risk weights if they meet certain criteria. Also, while acquisition, development, and construction (“ADC”) 
loans  will  generally  be  subject  to  heightened  risk  weights,  certain  exceptions  will  apply.  On  September 18,  2018,  the 
federal banking agencies issued a proposed rule modifying the agencies’ capital rules for HVCRE.

Notes to Consolidated Financial Statements (Continued) 

As of December 31, 2020, the most recent notification from the FDIC categorized all the Subsidiary Banks as 
well-capitalized under the regulatory framework for prompt corrective action. To be categorized as “well-capitalized,” we 
must maintain minimum Total risk-based, Tier 1 risk based, and Tier 1 leverage ratios as set forth in the table. There are 
no  conditions  or  events  since  that  notification  that  management  believes  have  changed  our  categorization  as 
well-capitalized. 

In December 2018, the federal bank regulators issued a final rule that would provide an optional three-year phase-
in period for the day-one regulatory capital effects of the adoption of ASU 2016-13 to ASC 326 “Financial Instruments – 
Credit Losses,” as amended, on January 1, 2020.

(21) Fair Value 

ASC  Topic  820,  “Fair  Value  Measurements  and  Disclosures”  (“ASC  820”)  defines  fair  value,  establishes  a 
framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value 
measurements. ASC 820 applies to all financial instruments that are being measured and reported on a fair value basis. 
ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly 
transaction between market participants at the measurement date; it also establishes a fair value hierarchy that prioritizes 
the inputs used in valuation methodologies into the following three levels: 

•  Level 1 Inputs—Unadjusted quoted prices in active markets for identical assets or liabilities. 
•  Level 2  Inputs—Observable  inputs  other  than  Level 1  prices,  such  as  quoted  prices  for  similar  assets  or 
liabilities,  quoted  prices  in  markets  that  are  not  active;  or  other  inputs  that  are  observable  or  can  be 
corroborated by observable market data for substantially the full term of the assets or liabilities.

•  Level 3 Inputs—Unobservable inputs that are supported by little or no market activity and that are significant 
to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose 
value is determined using pricing models, discounted cash flow methodologies, or other valuation techniques, 
as well as instruments for which the determination of fair value requires significant management judgment 
or estimation. 

A description of the valuation methodologies used for instruments measured at fair value, as well as the general

For the years ended December 31, 2020 and December 31, 2019, debt investment securities available-for-sale are 
classified within Level 2 of the valuation hierarchy.  Equity securities with readily determinable fair values are classified 
within Level 1. For debt securities classified as Level 2 in the fair value hierarchy, 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.

Our assets measured at fair value on a non-recurring basis are limited to loans classified as Watch List – Doubtful 
and other real estate owned.  At December 31, 2019, assets measured at fair value on a non-recurring basis also included 
an equity investment without a readily determinable fair value.  The fair value of Watch-List Doubtful loans is derived in 
accordance with FASB ASC 310, “Receivables”.  They are primarily comprised of collateral-dependent commercial loans.   
As  the  primary  sources  of  loan  repayments  decline,  the  secondary  repayment  source,  the  collateral,  takes  on  greater 
significance.  Correctly evaluating the fair value becomes even more important.  Re-measurement of the loan to fair value 
is done through a specific valuation allowance included in the ACL.  The fair value of the loan is based on the fair value 
of the collateral, as determined through either an appraisal or evaluation process.  The basis for our appraisal and appraisal 
review process is based on regulatory guidelines and strives to comply with all regulatory appraisal laws, regulations, and 
the Uniform Standards of Professional Appraisal Practice. All appraisals and evaluations are “as is” (the property’s highest 
and best use) valuations based on the current conditions of the property/project at that point in time.  The determination of 
the fair value of the collateral is based on the net realizable value, which is the appraised value less any closing costs, when 
applicable.  As of December 31, 2020, we had approximately $18,361,000 of doubtful commercial collateral dependent 
loans, of which approximately $16,587,000 had an appraisal performed within the immediately preceding twelve months 
and of which approximately $1,283,000 had an evaluation performed within the immediately preceding twelve months. 
As of December 31, 2019, we had approximately $2,955,000 of doubtful commercial collateral dependent loans, of which

approximately  $1,426,000  had  an  appraisal  performed  within  the  immediately  preceding  twelve  months  and  of  which 
approximately $847,000 had an evaluation performed within the immediately preceding twelve months. 

The determination to either seek an appraisal or to perform an evaluation begins in weekly credit quality meetings, 
where  the  committee  analyzes  the  existing  collateral  values  of  the  doubtful  loans  and  where  obsolete  appraisals  are 
identified.  In order to determine whether we would obtain a new appraisal or perform an internal evaluation to determine 
the fair value of the collateral, the credit committee reviews the existing appraisal to determine if the collateral value is 
reasonable in view of the current use of the collateral and the economic environment related to the collateral.  If the analysis 
of the existing appraisal does not find that the collateral value is reasonable under the current circumstances, we would 
obtain a new appraisal on the collateral or perform an internal evaluation of the collateral.  The ultimate decision to get a 
new  appraisal  rests  with  the  independent  credit  administration  group.    A  new  appraisal  is  not  required  if  an  internal 
evaluation, as performed by in-house experts, is able to appropriately update the original appraisal assumptions to reflect 
current market conditions and provide an estimate of the collateral’s market value for impairment analysis.  The internal 
evaluations must be in writing and contain sufficient information detailing the analysis, assumptions and conclusions and 
they must support performing an evaluation in lieu of ordering a new appraisal. 

Other real estate owned is comprised of real estate acquired by foreclosure and deeds in lieu of foreclosure. Other 
real estate owned is carried at the lower of the recorded investment in the property or its fair value less estimated costs to 
sell such property (as determined by independent appraisal) within Level 3 of the fair value hierarchy. Prior to foreclosure, 
the value of the underlying loan is written down to the fair value of the real estate to be acquired by a charge to the ACL 
(formerly allowance for probable loan losses), if necessary. The fair value is reviewed periodically and subsequent write 
downs are made accordingly through a charge to operations. Other real estate owned is included in other assets on the 
consolidated  financial  statements.  For  the  twelve  months  ended  December 31,  2020,  2019  and  2018,  we  recorded 
approximately $22,000, $9,611,000 and $170,000, respectively, in charges to the ACL in connection with loans transferred 
to other real estate owned. For the twelve months ended December 31, 2020, 2019 and 2018, we recorded approximately 
$1,539,000, $322,000 and $3,071,000, respectively, in adjustments to fair value in connection with other real estate owned. 

The  fair  value  estimates,  methods,  and  assumptions  for  our  financial  instruments  at  December 31,  2020  and 

December 31, 2019 are outlined below. 

Cash and Cash Equivalents 

For these short-term instruments, the carrying amount is a reasonable estimate of fair value. 

Investment securities held-to-maturity 

The carrying amounts of investments held-to-maturity approximate fair value. 

Investment Securities 

For  debt  investment  securities,  which  include  U.S.  Treasury  securities,  obligations  of  other  U.S.  government 
agencies, obligations of states and political subdivisions and mortgage pass through and related securities, fair values are 
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. See disclosures of fair 
value of investment securities in Note 2. 

Loans 

Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by 
type such as commercial, real estate and consumer loans as outlined by regulatory reporting guidelines. Each category is 
segmented into fixed and variable interest rate terms and by performing and non-performing categories.

Notes to Consolidated Financial Statements (Continued) 

For variable rate performing loans, the carrying amount approximates the fair value. For fixed rate performing 
loans,  except  residential  mortgage  loans,  the  fair  value  is  calculated  by  discounting  scheduled  cash  flows  through  the 
estimated maturity using estimated market discount rates that reflect the credit and interest rate risk inherent in the loan. 
For  performing  residential  mortgage  loans,  fair  value  is  estimated  by  discounting  contractual  cash  flows  adjusted  for 
prepayment estimates using discount rates based on secondary market sources or the primary origination market. Fixed 
rate performing loans are within Level 3 of the fair value hierarchy. At December 31, 2020 and December 31, 2019, the 
carrying amount of fixed rate performing loans was $1,812,413,000 and $1,503,811,000, respectively, and the estimated 
fair value was $1,747,257,000 and $1,481,239,000, respectively. 

Accrued Interest 

The carrying amounts of accrued interest approximate fair value. 

Deposits 

The fair value of deposits with no stated maturity, such as non-interest bearing demand deposit accounts, savings 
accounts and interest-bearing demand deposit accounts, was equal to the amount payable on demand as of December 31, 
2020 and December 31, 2019. The fair value of time deposits is based on the discounted value of contractual cash flows. 
The discount  rate  is  based on  currently  offered  rates.  Time  deposits  are  within  Level 3 of  the  fair  value  hierarchy.  At 
December 31,  2020  and  December 31,  2019,  the  carrying  amount  of  time  deposits  was  $2,153,541,000  and 
$2,012,300,000, respectively, and the estimated fair value was $2,148,976,000 and $2,011,950,000, respectively. 

Securities Sold Under Repurchase Agreements 

Securities  sold  under  repurchase  agreements  are  short-term  maturities.  Due  to  the  contractual  terms  of  the 

instruments, the carrying amounts approximated fair value at December 31, 2020 and December 31, 2019.   

Junior Subordinated Deferrable Interest Debentures 

We  currently  have  floating  rate  junior  subordinated  deferrable  interest  debentures  outstanding.  Due  to  the 
contractual terms of the floating rate junior subordinated deferrable interest debentures, the carrying amounts approximated 
fair value at December 31, 2020 and December 31, 2019. 

Other Borrowed Funds 

We currently have long-term borrowings issued from the Federal Home Loan Bank (“FHLB”). At December 31, 
2019,  we  also  held  some  also  short-term  borrowings.    Due  to  the  contractual  terms  of  the  short-term  borrowings,  the 
carrying amounts approximated fair value at December 31, 2019. The long-term borrowings outstanding at December 31, 
2020 and December 31, 2019 are fixed-rate borrowings and the fair value is based on established market spreads for similar 
types  of  borrowings.    The  fixed-rate  long-term  borrowings  are  included  in  Level  2  of  the  fair  value  hierarchy.    At 
December 31,  2020,  and  December 31,  2019  the  carrying  amount  of  the  fixed-rate  long-term  FHLB  borrowings  was 
$436,372,000  and  $436,511,000,  respectively  and  the  estimated  fair  value  was  $480,475,000  and  $465,017,000 
respectively.   

Commitments to Extend Credit and Letters of Credit 

Commitments to extend credit and fund letters of credit are principally at current interest rates and therefore the 

carrying amount approximates fair value. 

Limitations 

Fair value estimates are made at a point in time, based on relevant market information and information about the 
financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one 
time of our entire holdings of a particular financial instrument. Because no market exists for a significant portion of our

Notes to Consolidated Financial Statements (Continued) 

financial  instruments,  fair  value  estimates  are  based  on  judgments  regarding  future  expected  loss  experience,  current 
economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective 
in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. 
Changes in assumptions could significantly affect the estimates. 

Fair  value  estimates  are  based  on  existing  on-and  off-statement  of  condition  financial  instruments  without 
attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered 
financial instruments. Other significant assets and liabilities that are not considered financial assets or liabilities include 
the bank premises and equipment and core deposit value. In addition, the tax ramifications related to the effect of fair value 
estimates have not been considered in the above estimates.
