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

Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations  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, 2023. The following discussion should be read in conjunction with our Annual 
Report on Form 10-K for the year ended December 31, 2023, 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  those  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. 

•  Changes in consumer spending, borrowing, and saving habits. 
•  Changes  in  interest  rates  and  market  prices,  including  changes  in  federal  regulations  on  the  payment  of 

interest on demand deposits. 

•  Changes in our ability to retain or access deposits due to changes in public confidence in the banking system 
and  the  potential  threat  of  bank-run  contagion  fueled  by,  among  other  factors,  economic  instability, 
inflationary  pressures,  the  public’s  increased  exposure  to  social  media,  and  the  rapid  speed  at  which 
communication and coordination via social media can occur. 

•  Changes in the capital markets we utilize, including changes in the interest rate environment that may reduce

Overview 

We  are  headquartered  in  Laredo,  Texas,  with  166  facilities  and  256  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 interest 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 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 their 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, 2023 was 15.41% as compared to 12.52% for the year ended December 31, 2022. 

We are highly active in facilitating trade along the United States border with Mexico. We do a significant 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. 

Expense control is an essential element of our long-term profitability. It has been a constant focus of ours for 
many years and is especially critical during periods of economic uncertainty. As a result, we have achieved a decrease of 
approximately 11.1% or $34.4 million, before tax, in non-interest expense over the four-year period ended December 31, 
2023, primarily driven by decreases in our employee compensation and benefit plan expenses, professional fees, and other 
general operating expenses with the ultimate goal of ensuring that we align our workforce and operating expenses with 
our revenue streams.  

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,  create  efficiencies,  and  institute  cost-control 
protocols at all levels.  We will continue to closely 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. 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 for the year ended December 31, 2023 increased by 37.1% compared to the same period of 2022. Net 
income for the year ended December 31, 2023 was positively impacted by an increase in net interest income, which is 
primarily attributable to an increase in the size of our investment portfolio, the interest earned on funds held at the Federal 
Reserve  Bank,  and  an  increase  in  loan  interest  income,  of  which  the  latter  two  have  increased  consistently  with  FRB 
actions to raise interest rates in 2022 and 2023.  Net income for the period has also been impacted by increases in interest 
expense, primarily driven by an increase in interest paid on deposits.  We closely monitor rates paid on deposits to remain 
competitive in the current economic environment and retain deposits.  The increase in those revenue streams coupled with 
the cost control initiatives to streamline operations and increase efficiency in recent years have been the primary drivers 
in achieving these results.  Net income for the year ended December 31, 2022 compared to the same period of 2021 was 
also positively impacted by the same factors that impacted the twelve months ended December 31, 2023.  Non-interest 
income for the year ended December 31, 2022 was also positively impacted by gains on the sale of some properties from 
our branch network as we continue to monitor and evaluate our retail branch footprint and align with customer activity.

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.

 — 

(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. 

The increase in net interest income for the years ended December 31, 2023 and December 31, 2022 is primarily 
attributable to an increase in the size of our investment portfolio, the interest earned on funds held at the Federal Reserve 
Bank, and an increase in loan interest income, of which the latter two have increased in line with FRB actions to raise 
interest rates in 2022 and 2023. 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.

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  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, 2023 was adequate to absorb expected losses from loans and 
other financial instruments in the portfolio at that date. See Critical Accounting Policies on page 19.

Total non-interest income for the year ended December 31, 2023 decreased by 9.2% compared to the same period 
of 2022.  The decrease is primarily attributed to losses recorded on merchant banking investments.  Total non-interest 
income for the year ended December 31, 2022 decreased by 15.8% compared to 2021. Non-interest income was positively 
impacted  due  to  an  increase  in  service  charges  on  deposit  accounts  as  customer  activity  continues  to  increase  from 
previously depressed levels resulting from the COVID-19 pandemic. Other income was positively impacted by gains on 
the sale of some properties from our branch network as we continue to monitor and evaluate our retail branch footprint 
and  align  with  customer  activity.  The  decrease  in  other  investment  income  for  the  year  ended  December 31,  2022 
compared to the same period of 2021 was primarily attributable to the sale of an equity interest in a merchant banking 
investment held by one of our non-bank subsidiaries in the second quarter of 2021.

Non-interest expense for the year ended December 31, 2023 increased by 1.8% compared to the same period of 
2022.    The  increase  in  non-interest  expense  is  primarily  attributed  to  an  increase  in  our  employee  compensation  and

benefits cost as we continue to review and adjust our compensation and benefits programs to recognize performance and 
retain our workforce and an increase in software and software maintenance costs. Non-interest expense was positively 
impacted by a net gain recognized on the operations and sales of certain of our other real estate owned.  Non-interest 
expense for the year ended December 31, 2022 increased by 2.7% compared to the same period of 2021. The increase is 
primarily attributable to an increase in our employee compensation and benefits costs. We continue to monitor and manage 
our controllable non-interest expenses through a variety of measures with the ultimate goal of ensuring we align non-
interest expenses with our operations and revenue streams.         

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.

Residential  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 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.

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

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, 2023 were $11,824,554,000, 
a  decrease  of 6.6% from $12,660,007,000 at  December 31,  2022.   Deposits decreased  as  a  result of increased general 
activities by customers, increased competition for deposits by the federal government, and aggressive competitors’ pricing.  
We have closely monitored the rates paid on deposits by competitors and have made changes to our pricing accordingly 
in order to remain competitive in an effort to retain deposits.  Because of our significant levels of liquidity, we actively 
monitor deposit accounts, and in some cases determine that it is our best interest to allow some deposits to runoff because 
the rates being offered by our competitors are beyond levels we are willing to pay at this point in time.  Those actions are 
carefully considered by our executive leadership team in order to manage our deposit base and the cost of our deposits.  
Our  five  separately  chartered  Subsidiary  Banks  within  our  holding  company  structure  also  allows  us  to  work  with 
customers to maximize their FDIC deposit insurance levels.    

Other Borrowed Funds 

Other borrowed funds include FHLB borrowings which are long-term borrowings issued by the FHLB of Dallas 
or 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, 2023, other borrowed funds 
totaled $10,745,000, a decrease of 1.8% from $10,944,000 at December 31, 2022.

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 2023 and 2022 were 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. Our Subsidiary Banks also have an active 
account and significant collateral pledged to the Federal Reserve Bank’s Discount Window, which can also be relied upon 
to fund liquidity needs.  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,  2023,  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, 2023, in decreasing rate scenarios of -100,

-200, -300 and -400 basis points and 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, for the first 12-month period projected. At December 31, 2023, the most recent income simulations show that 
a rate shift of -100, -200, -300, -400, +100, +200, +300 and +400 basis points in interest rates up will vary projected net 
interest income for the coming 12-month period by -7.78%, -14.54%, -20.92%, -26.70% +6.48%, +13.14%, +19.80% and 
+26.51%, 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 of the Notes to Consolidated Financial Statements. At December 31, 2023, the 
aggregate amount legally available to be distributed to us from our Subsidiary Banks as dividends was approximately 
$1,229,500,000, assuming that each Subsidiary Bank continues to be classified as “well capitalized” under the applicable 
regulations  in  effect  at  December 31,  2023.  The  restricted  capital  (capital  and  surplus)  of  our  Subsidiary  Banks  was 
approximately  $1,377,321,000  as  of  December 31,  2023.  The  undivided  profits  of  our  Subsidiary  Banks  were 
approximately $1,710,438,000 as of December 31, 2023.  

At December 31, 2023, we had outstanding $10,745,000 in other borrowed funds and $108,868,000 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,  2023,  shareholders’  equity  was  $2,447,774,000  compared  to  $2,044,759,000  at  December 31,  2022,  an 
increase of $403,015,000, or 19.7%. Shareholders’ equity increased primarily due to an increase in retained earnings and 
a  decrease  in  accumulated  other  comprehensive  loss  as  a  result  of  market  interest  conditions  and  the  impact  of  those 
conditions  on the  value  of  our  investment portfolio.  The accumulated other  comprehensive  loss  is not  included  in the 
calculation of regulatory capital ratios. 

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

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).  All banks are required 
to have Tier 1 capital of at least 4 % of risk-weighted assets and total capital of 8% 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 22.39% and 21.04% and risk-weighted total capital ratios of 23.65% and 22.22% as of December 31, 2023 
and 2022, respectively, which are well above the minimum regulatory requirements and exceed the well-capitalized ratios 
(see Note 19 of our Notes to Consolidated Financial Statements).

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 related 
capital provisions of the Dodd-Frank Act. Consistent with the Basel international framework, the rules include a minimum 
ratio of Common Equity Tier 1 (“CET1”) capital to risk-weighted assets of 4.5% and a CET1 capital conservation buffer 
of 2.5% of risk-weighted assets, effectively resulting in a minimum ratio of CET1 capital to risk-weighted assets of at least 
7% upon full implementation. The 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.  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. We believe that as of December 31, 2023, we meet all fully 
phased-in capital adequacy requirements. 

In November 2017, the OCC, the FRB 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. Pursuant to rules issued by the federal bank 
regulatory agencies in February 2019 and March 2020, banking organizations were given options to phase in the adoption 
of  CECL  over  a  three-year  transition  period  through  December 31,  2022  or  over  a  five-year  transition  period  through 
December 31, 2024.  Rather  than  electing  to  make one  of  the  phase-in options, we  immediately  recognized  the  capital 
impact upon adopting the CECL accounting standards on January 1, 2020, which resulted in an increase in our allowance 
for probable loan losses and a one-time cumulative-effect adjustment to retained earnings upon adoption. 

In December 2017, the Basel Committee on Banking Supervision unveiled its final set of standards and reforms 
to  the  Basel  III  regulatory  capital  framework,  commonly  called  “Basel  III  Endgame”  or  “Basel  IV.”    The  Basel  IV 
standards  make  changes  to  the  capital  framework  first  introduced  as  “Basel  III”  in  2010  and  aim  to  reduce  excessive 
variability in banks’ calculations of risk-weighted assets and risk-weighted capital ratios.  Implementation of Basel IV 
began  on  January 1,  2023  and  will  continue  over  a  five-year  transition  period  by  regulators  in  individual  countries, 
including the U.S. federal bank regulatory agencies (after notice and comment). 

Junior Subordinated Deferrable Interest Debentures 

We currently have four 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”) each issued capital and common securities (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, 2023 and December 31, 2022, the principal amount of debentures 
outstanding totaled $108,868,000 and $134,642,000, respectively.  

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 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, 2023 and December 31, 2022, the total $108,868,000 and $134,642,000, 
respectively, 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. 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 and 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 spaces. 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 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. 

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 

20 

 
 
 
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) the  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 troubled loan modifications, (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,  geopolitical  events  and  large  loans.  The  large  loan  operational  risk  factor  was  added 
beginning in the second quarter of 2023.  Because of the magnitude of large loans, they pose a higher risk of default.  
Recognizing  this  risk  and  establishing  an  operational  risk  factor  to  capture  that  risk,  is  prudent  action  in  the  current 
economic  environment.   Large  loans  are usually part of a  larger  relationship with  collateral  that  is  pledged  across  the 
relationship.  Defaulting on a larger loan may therefore jeopardize an entire collateral relationship.  The current economic 
environment has created challenges for borrowers to service their debt.  Increasing cap rates, elevated office vacancies, an 
upward trend in apartment vacancies and significant increases in interest rates are all contributing to the elevated risk in 
large loans.   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.

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 
February 21, 2023, the Board of Directors extended and increased the repurchase program to purchase up to $124 million 
of  common  stock  during  the  12-month  period  commencing  on  March 15,  2023.  On  February 20,  2024,  our  Board  of 
Directors authorized the renewal and increase of the repurchase program to purchase up to $150 million of common stock 
during the 12-month period commencing on March 15, 2024 upon the expiration of our current repurchase program on 
that date.  Shares of common stock may be purchased from time to time on the open market or through privately negotiated 
transactions. Shares purchased in this program will be held in treasury for reissue for various corporate purposes, including 
employee compensation plans. During the fourth quarter of 2023, the Board of Directors adopted a Rule 10b-18 trading 
plan and a Rule 10b5-1 trading plan and intends to adopt additional Rule 10b-18 and Rule 10b5-1 trading plans, which 
will allow us to purchase shares of our common stock during certain open and blackout periods when we ordinarily would 
not be in the market due to trading restrictions in our insider trading policy. During the terms of both a Rule 10b-18 and 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 these trading plans will be held in treasury for reissue for various corporate

repurchased  under  all  programs  at  a  cost  of  $414,926,000.  We  are  not  obligated  to  purchase  shares  under  our  stock 
repurchase program outside of the Rule 10b-18 and  Rule 10b5-1 trading plans. 

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

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of International Bancshares Corporation and its
subsidiaries

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, 2023 and 2022, 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, 2023, 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, 2023 and
2022, and the results of its operations and its cash flows for each of the three years in the period ended 
December 31, 2023, 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, 2023, 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 26, 2024 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 audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement, whether due to error or fraud. Our audits included performing procedures
to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and
performing procedures that respond to those risks. Such procedures included examining, on a test basis,
evidence regarding the amounts and disclosures in the financial statements. Our audits also included 
evaluating the accounting principles used and significant estimates made by management, as well as 
evaluating the overall presentation of the financial statements. We believe that our audits provide a 
reasonable basis for our opinion.

Critical Audit Matter
The critical audit matter communicated below is a matter arising from the current period audit of the 
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

Allowance for Credit Losses  
As described in Note 4 of the consolidated financial statements, the Company established an allowance 
for credit losses totaling $157,069,000 as of December 31, 2023. The allowance for credit losses is 
derived from 1) a loss-rate methodology that measures lifetime losses on loan pools that have similar risk 
characteristics; and 2) estimated losses on individually evaluated loans that do not have similar risk 
characteristics. 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 loan modifications 
(TLM’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, geopolitical events and large 
loans.  

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.

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, IBC Capital Corporation and Diamond Beach 
Holdings, LLC.  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 highly 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 the allowance for credit losses (“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 (loss) and in shareholders’ equity as accumulated other comprehensive income (loss) until realized. 
Unrealized gains and losses related to equity securities with readily determinable fair values are included in net income. 
Available-for-sale and held-to-maturity debt securities in an unrealized loss position are 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- 

35 

 
INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 

Notes to Consolidated Financial Statements (Continued) 

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, 2023 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 periods. We did not maintain any trading securities during the three-year period ended December 31, 2023.  

Mortgage-backed  securities  held  at  December 31,  2023  and  2022  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 

Equity  securities  with  readily  determinable fair  values  at  December 31, 2023  and  December 31,  2022  consist 
primarily of Community Reinvestment Act funds. Unrealized gains and losses on the equity securities are recognized in 
net income. 

Provision and Allowance for Credit Losses 

Our ACL is based on 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.  

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 

36 

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 

Notes to Consolidated Financial Statements (Continued) 

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 (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 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.

Troubled Loan Modifications 

We adopted the provisions of Accounting Standards Update No. 2022-02, Financial Instruments – Credit Losses 
(Topic 326): Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”) on January 1, 2023.  ASU 2022-02 
eliminates the accounting guidance for troubled debt restructurings (“TDR”) in existing guidance and enhances disclosure 
requirements for certain loan refinancings and restructurings when a borrower is experiencing financial difficulty.  We 
occasionally provide modifications to borrowers experiencing financial difficulties.  Modifications may include certain 
concessions  that  we  evaluate  under  ASU  2022-02  to  determine  the  need  for  disclosure.    Concessions  to  borrowers 
experiencing financial difficulties that would require disclosure include principal forgiveness, term extension, an other-
than-insignificant payment delay, an interest rate reduction or a combination of these concessions, collectively referred to 
as troubled loan modifications. In accordance with the provisions of ASU 2022-02, we ceased recognition of TDR loans 
after adopting ASU 2022-02 on January 1, 2023.  Prior to the adoption of ASU 2022-02, TDR loans were those loans 
where, for reasons related to a borrower’s difficulty to repay a loan, we granted a concession to the borrower that we would 
not have normally considered in the normal course of business. Short term-deferrals were not considered a TDR.  The 
terms that may have been modified included 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 
$26,728,000 and $30,144,000 at December 31, 2023 and 2022, 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 
$236,000 and $4,637,000 at December 31, 2023 and 2022, 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 
(Topic 842).”   

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 

Our revenue is primarily comprised of net interest income on financial assets and liabilities, which are excluded 
from  the  scope  of ASU  2014-09,  “Revenue  from  Contracts  with  Customers  (Topic  606).”  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 accounting standards 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, 2023 and 2022, 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, 2023, 2022, and 2021, 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 2020.

Stock Options and Stock Appreciation Rights 

Compensation expense for stock-based 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 and stock appreciation rights granted was estimated using a Black-Scholes-Merton pricing model. These models 
were developed for use in estimating the fair value of publicly traded options and stock appreciation rights that have no 
vesting  restrictions  and  are  fully  transferable.  Additionally,  these  models  require  the  input  of  highly  subjective 
assumptions. Because our employee stock options and stock appreciation rights have characteristics significantly different 
from those of publicly traded options and appreciation rights, and because changes in the subjective input assumptions can 
materially  affect  the  fair  value  estimate,  in  management’s  opinion,  the  Black-Scholes-Merton  pricing  models  do  not 
necessarily provide a reliable single measure of the fair value of our stock options and stock appreciation rights. 

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, 
2023, 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,  2023,  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 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 did not have a significant impact on our consolidated financial statements.  

In  March 2022,  the  FASB  issued  Accounting  Standards  Update  No. 2022-02,  Financial  Instruments –  Credit 
Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”).  ASU 2022-02 eliminates 
the accounting guidance for troubled debt restructurings in existing guidance and enhances disclosure requirements for 
certain  loan  refinancings  and  restructurings  when  a  borrower  is  experiencing  financial  difficulty.    Additionally,  ASU 
2022-02 requires entities to disclose current period gross write-offs by year of origination for financing receivables and net 

41 

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 

Notes to Consolidated Financial Statements (Continued) 

investments in leases. We adopted the provisions of ASU 2022-02 on January 1, 2023 and it did not have a significant 
impact on our consolidated financial statements.  

In March 2023, the FASB issued Accounting Standards Update No. 2023-02, Investments in Equity Method and 
Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization 
Method. ASU 2023-02 modifies existing guidance to allow for use of the proportional amortization method for all tax 
equity investments, regardless of the tax credit program from which the income tax credits are received if certain conditions 
are met.   ASU 2023-02 also requires specific disclosures of all investments that generate income tax credits and other 
income tax benefits from a tax credit program for which an entity has elected to apply the proportional amortization method 
in annual and interim periods.  The provisions of ASU 2023-02 are effective for fiscal years beginning after December 15, 
2023  and  we  do  not  anticipate  that  the  adoption  of  ASU  2023-02  will  have  a  significant  impact  on  our  consolidated 
financial statements.   

In  October 2023,  the  FASB  issued  Accounting  Standards  Update  No. 2023-06,  Disclosure  Improvements:  
Codification  Amendments  in  Response  to  the  SEC’s  Disclosure  Update  and  Simplification  Initiative.    ASU  2023-06 
modifies  the  disclosure  and  presentation  requirements  of  various  topics  to  align    disclosures  with  SEC  Release 
No. 33-10532,  Disclosure  Update  and  Simplification,  which  was  issued  in  August 2018.    ASU  2023-06  also  provides 
clarifications or technical corrections of certain current  disclosure requirements.  The provisions of ASU 2023-06 are 
effective on the date in which the SEC removal of the related disclosure from Regulation S-X or Regulation S-K, with 
early adoption prohibited.  The adoption of ASU 2023-06 is not expected to have a significant impact on our consolidated 
financial statements. 

In  November 2023,  the  FASB  issued  Accounting  Standards  Update  No. 2023-07,  Segment  Reporting  (Topic 
280):  Improvements  to  Reportable  Segment  Disclosures.    ASU  2023-07  expands  segment  disclosure  requirements  for 
public entities, primarily through enhanced disclosures about significant segment expenses and other segment items on an 
annual and interim basis.  ASU 2023-07 also requires full segment disclosures, currently only required in annual periods, 
to be included in interim periods as well.  ASU 2023-078 is effective for fiscal years beginning after December 15, 2024.  
The adoption of ASU 2023-07 is not expected to have a significant impact on our consolidated financial statements. 

In  December 2023,  the  FASB  issued  Accounting  Standards  Update  No. 2023-09,  Income  Taxes  (Topic  740): 
Improvements  to  Income  Tax  Disclosures,  an  Amendment.    ASU  2023-09  is  intended  to  enhance  transparency  and 
decisions usefulness of income tax disclosures.  ASU 2023-09 requires that public entities disclose specific categories in 
the annual rate reconciliation and provides additional guidance for reconciling items that meet a quantitative threshold.  
Explanation of individual reconciling items is also required.  ASU 2023-09 also requires certain disclosures regarding 
income taxes paid, including disaggregation of taxes paid (net of refunds) by federal, state and foreign taxes, including 
disaggregation  by  individual  jurisdictions  in  which  taxes  paid  (net  of  refunds),  exceed  a  quantitative  threshold.    The 
provisions of ASU 2023-09 are effective for annual periods beginning after December 15, 2024.  The adoption of ASU 
2023-09 is not expected to have a significant impact on our consolidated financial statements.   

(2) Investment Securities, Equity Securities with Readily Determinable Fair Values and Other Investments 

Available-for-sale  and  held-to-maturity  debt  securities  in  an  unrealized  loss  position  are  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, 2023 and December 31, 2022, and have determined that no 
debt securities in an unrealized loss position are arising from credit related reasons, and have therefore not recorded any 

42 

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES

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.

Included  in  the  carrying  value  of  residential  mortgage-  backed  securities  are  $681,121  of  mortgage-backed  securities  issued  by  Ginnie  Mae, 
$3,528,091 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 
$1,836,634,000 and $1,598,853,000, respectively, at December 31, 2023. 

Proceeds from the sale and call of securities available-for-sale were $2,045,000, $800,000, and $5,890,000 during 
2023, 2022 and 2021, respectively, which amounts included $0, $0 and $0 of mortgage-backed securities. Gross gains of 
$0, $0 and $0, and gross losses of $3,000, $0 and $16,000 were realized on the sales and calls in 2023, 2022 and 2021,

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,  2023  and  December 31,  2022,  the  balance  in  equity  securities  with  readily  determinable  fair  values 
recorded  at  fair  value  were  $5,417,000  and  $5,358,000,  respectively.  The  following  is  a  summary  of  unrealized  and 
realized gains and losses recognized in net income on equity securities for the twelve months ended December 31, 2023,

Other  investments  include  equity  and  merchant  banking  investments  held  by  our  subsidiary  banks  and  non-
banking entities. We hold ownership interests in limited partnerships for the purpose of investing in low-income housing 
tax credit (“LIHTC”) projects. The partnerships may acquire, construct, or rehabilitate housing for low- and moderate-
income individuals. We realize a return primarily from federal tax credits and other federal tax deductions associated with 
the underlying projects. We are a limited partner in the partnerships, and not required to consolidate the entities in our 
consolidated  financial  statements.  Investments  in  LIHTC  projects  totaled  $200,245,000  at  December 31,  2023  and 
$214,549,000  at  December 31,  2022  and  are  included  in  other  investments  on  the  consolidated  financial  statements.

(4) Allowance for Credit Losses 

We adopted the provisions of ASU 2016-13, Financial Instruments – Credit Losses (Topic 326):  Measurement 
of Credit Losses on Financial Instruments 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 were calculated and presented in accordance with previously applicable 
U.S. GAAP.  

ASU 2016-13 replaces the long-standing incurred-loss model with a current expected credit loss model (“CECL”) 
that recognizes credit losses over the life of a financial asset. Using the CECL methodology, 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 and 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 spaces. 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 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. 

47 

 
 
INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 

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) the  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 troubled loan modifications, (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,  geopolitical  events  and  large  loans.  The  large  loan  operational  risk  factor  was  added 
beginning in the second quarter of 2023.  Because of the magnitude of large loans, they pose a higher risk of default.  
Recognizing  this  risk  and  establishing  an  operational  risk  factor  to  capture  that  risk,  is  prudent  action  in  the  current 
economic  environment.   Large  loans  are usually part of a  larger  relationship with  collateral  that  is  pledged  across  the 
relationship.  Defaulting on a larger loan may therefore jeopardize an entire collateral relationship.  The current economic 
environment has created challenges for borrowers to service their debt.  Increasing cap rates, elevated office vacancies, an 
upward trend in apartment vacancies and significant increases in interest rates are all contributing to the elevated risk in 
large loans.    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 

48

Notes to Consolidated Financial Statements (Continued) 

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 losses is a reserve established through a provision for credit losses charged to expense, 
which  represents  management’s  best  estimate  of  probable  loan  losses  when  evaluating  loans  (i) individually  or 
(ii) collectively. The credit loss charged to expense has increased for the twelve months ended December 31, 2023 compared 
to the same periods of 2022 and 2021 in order to provide some protection from potential losses in our loan portfolio given

the high level of uncertainty in the economy and a potential economic recession on the horizon.  We have increased the 
severity of some of the qualitative loss factors in certain pools of the portfolio to encompass the economic uncertainty, 
resulting in an increase in the required ACL. The pool specific qualitative loss factors management deemed appropriate 
for the ACL calculation at December 31, 2022 remained constant in the December 31, 2023 calculation, with the exception 
of the large loan factor that was added to the ACL calculation in the second quarter of 2023.

Loans accounted for on a non-accrual basis at December 31, 2023, 2022 and 2021 amounted to $47,170,000, 
$51,648,000,  and  $1,921,000,  respectively.  The  increase  in  non-accrual  loans  at  December 31,  2022  is  primarily 
attributable to two loans that were placed on non-accrual at the end of the fourth quarter of 2022. One relationship is 
secured by equipment used in the oil and gas industry and one is secured by real estate. The effect of such non-accrual 
loans reduced interest income by approximately $6,614,000, $116,000, and $169,000 for the years ended December 31, 
2023, 2022, and 2021, 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, 2023, 2022, and 2021 amounted to approximately $5,597,000, 
$6,132,000, and $8,642,000, respectively.

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  adopted  the  provisions  of  Accounting  Standards  Update  2022-02,  Financial  Instruments –  Credit  Losses 
(Topic 326): Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”) on January 1, 2023.  ASU 2022-02 
eliminates  the  accounting  guidance  for  troubled  debt  restructurings  in  existing  guidance  and  enhances  disclosure 
requirements  for  certain  loan  refinancings  and  restructurings  when  a  borrower  is  experiencing  financial  difficulty.  
Additionally, ASU 2022-02 requires entities to disclose current period gross write-offs by year of origination for financing 
receivables  and  net  investments  in  leases.    The  adoption  of  ASU  2022-02  did  not  have  a  significant  impact  on  our 
consolidated financial statements.   

We  occasionally  provide  modifications  to  borrowers  experiencing  financial  difficulties.    Modifications  may 
include certain concessions that we must evaluate under ASU 2022-02 to determine the need for disclosure.  Concessions 
to borrowers experiencing financial difficulties that would require disclosure include principal forgiveness, term extension, 
an other-than-insignificant payment delay, an interest rate reduction or a combination of these concessions.  For the twelve 
months  ended  December 31,  2023,  we  did  not  provide  any  material  modifications  under  these  circumstances  to  any 
borrower experiencing financial difficulty that would require disclosure.   

Under guidance in effect prior to January 1, 2023, the following table details loans accounted for as “troubled 
debt restructuring,” segregated by loan class. Loans accounted for as troubled debt restructuring are included in impaired 
loans.

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, 2023 
and December 31, 2022, was adequate to absorb expected losses from loans in the portfolio at that date.

The increase in Commercial loans past due 90 days or greater at December 31, 2023 can be primarily attributed 
to a loan secured by equipment and other assets used in the oil and gas industry and oil and gas production that is on 
non-accrual.  The increase in Commercial Real Estate:  Other Construction & Land Development loans past due 90 days 
or  greater  can  be  primarily  attributed  to  a  loan  secured  by  commercial  property  that  is  on  non-accrual.    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.

The increase in Watch-List Pass Commercial loans at December 31, 2023 compared to December 31, 2022 can 
be primarily attributable to a relationship secured by commercial vehicles, which was downgraded from Pass.  The increase 
in Commercial Real Estate: Construction and Development loans at December 31, 2023 compared to December 31, 2022 
can be primarily attributable to the downgrade of two relationships secured by land for future development and land for 
hotel development from Pass.  The increase in Commercial Real Estate: Farmland and Commercial loans at December 31, 
2023 can be attributed to the downgrade of two relationships.  One relationship is secured by a retail shopping center and 
one is secured by a hotel.

(1)  Long-term advances at December 31, 2023 and December 31, 2022 consisted of amortizing and non-amortizing advances. The non-amortizing 
advances  totaling  $425,000,000  were  called  by  the  Federal  Home  Loan  bank  in  the  fourth  quarter  of  2022.  Two  amortizing  advances  are 
outstanding at December 31, 2023 in the amounts of $2,914,000 and $7,831,000 and mature in December 2033 and November 2033, respectively. 
The amortization on the amortizing long-term advances totals approximately $204,000, $210,000, $215,000, $221,000 and $227,000 for the years 
ending December 31, 2024, 2025, 2026, 2027 and December 31, 2028, respectively.  

(10) Junior Subordinated Deferrable Interest Debentures 

We currently have four 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”) each issued capital and common securities (“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,  2023  and  December 31,  2022,  the  principal  amount  of  debentures 
outstanding totaled $108,868,000 and $134,642,000, respectively.  

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 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, 2023 and December 31, 2022, the total $108,868,000 and $134,642,000, 
respectively, 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

(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 $4,011,000, $4,300,000, and 
$3,550,000 were charged to income for the years ended December 31, 2023, 2022, and 2021, 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.

(15) Stock Options and Stock Appreciation Rights 

On April 5, 2012, the Board of Directors adopted the 2012 International Bancshares Corporation Stock Option 
Plan (the “2012 Plan”). There were 800,000 shares of common stock available for stock option grants under the 2012 Plan, 
which were qualified incentive stock options (“ISOs”) or non-qualified stock options. 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. On April 4, 2022, the 2012 Plan expired and was not renewed. 

The  fair  value  of  each  option  award  granted  under  the  plan  was  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 
was based on the historical volatility of the price of our stock. We used historical data to estimate the expected dividend 
yield and employee termination rates within the valuation model. The expected term of options was derived from historical 
exercise behavior. The risk-free rate for periods within the contractual life of the option was based on the U.S. Treasury 
yield curve in effect at the time of grant.

On April 18, 2022, the Board of Directors adopted the 2022 International Bancshares Stock Appreciation Rights 
Plan (the “SAR Plan”). There are 750,000 shares of underlying common stock that may be used for stock appreciation 
right (“SAR”) grants under the plan, however, no actual shares will be granted. Upon exercise, the SAR will be settled in 
cash. SARs granted may be exercisable for a period of up to 10 years from the date of grant and may vest over an eight-
year period. As of December 31, 2023, a total of 465,250 SARS had been issued under the SAR Plan.

The fair value of the liability for payments due to stock appreciation rights holders at December 31, 2023 and 
December 31, 2022 is approximately $1,464,000 and $546,000, respectively, as calculated using a Black-Scholes-Merton 
model, and is included in other liabilities on the consolidated statements of condition. The expense recorded in connection 
with  all  grants  under  the  SAR  Plan  totaled  $918,000  and  $546,000,  respectively,  for  the  twelve  months  ended 
December 31,  2023  and  December 31,  2022.  As  of  December 31,  2023,  there  was  approximately  $5,090,000  in 
unrecognized liability related to non-vested SARs granted under the plan that will be recognized over a weighted average 
period of 8.5 years. 

(16) 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; therefore no cash is required to be 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. 

(17) 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 $13,335,000 
and $28,708,000 at December 31, 2023 and 2022, respectively.

(18) 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, 2023, the following 
financial amounts of instruments, whose contract amounts represent credit risks, were outstanding (in thousands):

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, 2023, the maximum potential amount of future payments is approximately $147,190,000. At December 31, 
2023, the fair value of these guarantees is not significant. Unsecured letters of credit totaled approximately $23,677,000 
and $40,249,000 at December 31, 2023 and 2022, 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. 

(19) 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,  2023,  the  Subsidiary  Banks  could  pay  dividends  of  up  to 
$1,229,500,000 without prior regulatory approval and without adversely affecting their “well-capitalized” status under 
regulatory  capital  rules  in  effect  at  December 31,  2023.  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 

65 

 
 
 
 
INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 

Notes to Consolidated Financial Statements (Continued) 

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, 2023, that we met all capital 
adequacy requirements to which we are subject. 

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 
related capital provisions of the Dodd-Frank Act. Consistent with the Basel international framework, the rules include a 
new  minimum  ratio  of  Common  Equity  Tier  1  (“CET1”)  capital  to  risk-weighted  assets  of  4.5%  and  a  CET1  capital 
conservation buffer of 2.5% of risk-weighted assets, effectively resulting in a minimum ratio of CET1 capital to risk-
weighted  assets  of  at  least  7%  upon  full  implementation.  The  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.  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, 2023, we meet all fully phased-in capital adequacy requirements. 

In November 2017, the OCC, the FRB 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.  Pursuant to rules issued by the federal bank 
regulatory agencies in February 2019 and March 2020, banking organizations were given options to phase in the adoption 
of  CECL  over  a  three-year  transition  period  through  December 31,  2022  or  over  a  five-year  transition  period  through 
December 31, 2024.  Rather than electing to make one of the phase-in options, we immediately recognized the capital 
impact upon adopting CECL accounting standards on January 1, 2020, which resulted in an increase in our allowance for 
probable loan losses and a one-time cumulative-effect adjustment to retained earnings upon adoption. 

In December 2017, the Basel Committee on Banking Supervision unveiled its final set of standards and reforms 
to  its  Basel  III  regulatory  capital  framework,  commonly  called  “Basel  III  Endgame”  or  “Basel  IV.”    The  Basel  IV 
framework makes changes to the capital framework first introduced as “Basel III” in 2010 and aim to reduce excessive 
variability in banks’ calculations of risk-weighted capital ratios. Implementation of Basel IV began on January 1, 2023 
and will continue over a five-year transition period by regulators in individual countries, including the U.S. federal bank 
regulatory agencies (after notice and comment). 

As of December 31, 2023, our capital levels continue to exceed all capital adequacy requirements under the Basel 

III Capital Rules as currently applicable to us.

On  May 24,  2018,  the  Economic  Growth,  Regulatory  Relief  and  Consumer  Protection  Act  of  2018 
(“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 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. 

As of December 31, 2023, the most recent notification from the FDIC categorized all the Subsidiary Banks as

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,

For the years ended December 31, 2023 and December 31, 2022, 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. 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, 2023, 
we had approximately $46,491,000 of doubtful commercial collateral dependent loans, of which approximately $1,272,000 
had an appraisal performed within the immediately preceding twelve months and of which approximately $35,061,000

appraisal performed within the immediately preceding twelve months and of which approximately $51,326,000 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,  2023,  2022,  and  2021,  we  recorded 
approximately $0, $2,000, and $2,000, respectively, in charges to the ACL in connection with loans transferred to other 
real  estate  owned.  For  the  twelve  months  ended  December 31,  2023,  2022,  and  2021,  we  recorded  approximately 
$2,538,000, $1,627,000, and $2,655,000, 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,  2023  and 

December 31, 2022 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 may 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 – Investment Securities, Equity Securities with Readily Determinable Fair Values 
and Other Investments.

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. 

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, 2023 and December 31, 2022, the 
carrying amount of fixed rate performing loans was $1,199,347,000 and $1,203,381,000, respectively, and the estimated 
fair value was $1,073,892,000 and $1,100,848,000, 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, 
2023 and December 31, 2022. 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,  2023  and  December 31,  2022,  the  carrying  amount  of  time  deposits  was  $2,425,177,000  and 
$2,068,184,000, respectively, and the estimated fair value was $2,428,681,000 and $2,076,231,000, 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, 2023 and December 31, 2022.  

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, 2023 and December 31, 2022. 

Other Borrowed Funds 

We currently have long-term borrowings issued from the Federal Home Loan Bank (“FHLB”). The long-term 
borrowings  outstanding  at  December 31,  2023  and  December 31,  2022  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, 2023 and December 31, 2022 the carrying amount of the fixed-rate 
long-term  FHLB  borrowings  was  $10,745,000  and  $10,944,000,  respectively,  and  the  estimated  fair  value  was 
$10,745,000 and $10,944,000, 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 
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.
