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, 2024. The following discussion should be read in conjunction with our Annual 
Report on Form 10-K for the year ended December 31, 2024, 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. 
• 
The imposition of new or increased international tariffs and the impact of potential retaliatory tariffs, which 
may impact our subsidiary banks’ business and operations with Mexico. 
• 
Government intervention in the U.S. financial system. 
• 
The unavailability of funding from the FHLB, the Federal Reserve Bank (“FRB”) 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

Overview 
We are headquartered in Laredo, Texas, with 166 facilities and 255 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, 2024 was 13.66% as compared to 15.41% for the year ended December 31, 2023. 
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. 
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), may be impacted in the future if economic conditions deteriorate. 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. 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 

5 
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 
Net income for the year ended December 31, 2024 decreased by approximately 0.6% compared to the same period 
of 2023 and net income for the year ended December 31, 2023 increased by approximately 37.1% compared to the same 
period of 2022.   Net income for the year ended December 31, 2024 and the year ended December 31, 2023 was positively 
impacted by an increase in interest income earned on our investment and loan portfolios driven primarily by both an 
increase in the size of the portfolios and the rate environment, which remains elevated as a result of FRB actions to raise 
interest rates in recent years. Net interest income for the same periods has been negatively impacted by an increase in 
interest expense, primarily driven by increases on rates paid on deposits.  We closely monitor rates paid on deposits to 
remain competitive in the current economic environment and retain deposits.   
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 

6 
rates and changes in the amount and composition of interest-earning assets and interest-bearing liabilities. Tax-exempt 
yields have not been adjusted to a tax-equivalent basis.

The level of interest rates and the volume and mix of earning assets and interest-bearing liabilities impact net 
income and net interest margin. The yield on average interest-earning assets increased 5.2% from 5.77% in 2023 to 6.07% 
in 2024, and the rates paid on average interest-bearing liabilities increased 42.5% from 1.86% in 2023 to 2.65% in 2024. 
The yield on average interest-earning assets increased 59.4% from 3.62% in 2022 to 5.77% in 2023, and the rates paid on 
average interest-bearing liabilities increased 279.6% from 0.49% in 2022 to 1.86% in 2023.

(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, 2024 and December 31, 2023 is primarily 
attributable to an increase in interest income earned on our investment and loan portfolios, driven by both an increase in 
the size of such portfolios and the current rate environment, which remains elevated due to the FRB raising interest rates 
in 2022 and 2023.  The increase in interest income is being offset by an increase in interest expense due to changes in rates 
we pay on deposits to remain competitive with our competitors.  Net interest income is the spread between income on 
interest earning assets (e.g. loans and securities) and the interest expense on liabilities used to fund those assets (e.g. 
deposits, repurchase agreements and funds borrowed).  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 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, management may adjust the interest 
rate sensitive assets and liabilities in order to manage the effect of interest rate changes, as needed.

Allowance for Credit Losses 
The ACL decreased 0.3% to $156,537,000 at December 31, 2024 from $157,069,000 at December 31, 2023. The 
provision for credit losses charged to expense decreased $2,774,000 to $31,802,000 for the year ended December 31, 2024 
from $34,576,000 for the same period in 2023.

The ACL primarily consists of the aggregate ACLs 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, 2024 was adequate to absorb expected losses from loans and 
other financial instruments in the portfolio at that date. See Critical Accounting Policies on page 20.

Total non-interest income for the year ended December 31, 2024 increased by 4.1% compared to the same period 
of 2023.  The increase can be primarily attributed to an increase in other investment income when compared to the same 
period of 2023.  The decrease in 2023 was primarily attributed to losses recorded on certain merchant banking investments.  
Total non-interest income for the year ended December 31, 2023 decreased by 9.2% compared to 2022, which, as noted, 
was primarily impacted by some losses recorded on certain merchant banking investments. Other income for the year 
ended December 31, 2023 compared to 2022 primarily due to gains on the sale of some properties from our branch network 
as in 2022.

Non-interest expense for the year ended December 31, 2024 increased by 6.5% compared to 2023 and can be 
primarily be attributed to continued increases in our employee compensation and benefit costs as we continue to review 
and adjust our compensation and benefits programs to recognize performance and retain our workforce.  Non-interest 
expense for the year ended December 31, 2023 increased by 1.8% compared to 2022.  The increase can be primarily 
attributed to an increase in our employee compensation and benefit costs and an increase in software and software 
maintenance costs. Non-interest expense for the year ended December 31, 2023 was also positively impacted by a net gain 
recognized on the operations and sales of certain of our other real estate owned.  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.

International Operations 
On December 31, 2024, we had $186,561,000 (1.2% of total assets) in loans outstanding to borrowers domiciled 
in foreign countries, which included primarily borrowers domiciled in Mexico. The loan policies of our Subsidiary Banks 
generally require that loans to borrowers domiciled in foreign countries be primarily secured by assets located in the United 

13 
States or have credit enhancements in the form of guarantees from significant United States corporations. The composition 
of such loans as of December 31, 2024 and 2023 is presented below.

We offer a variety of deposit accounts having a wide range of interest rates and terms. We rely primarily on our 
high-quality customer service, sales programs, customer referrals, and advertising to attract and retain these deposits. 
Deposits provide the primary source of funding for our lending and investment activities, and the interest paid for deposits 
must be managed carefully to control the level of interest expense. Deposits at December 31, 2024 were $12,111,844,000, 
an increase of 2.4% from $11,824,554,000 at December 31, 2023.  Deposit balances increased for the twelve months ended 
December 31, 2024 compared to the same period of 2023, however, they have continued to fluctuate as a result of increased 
general activities by customers and increased competition for deposits as a result of aggressive pricing by competitors.  
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.  The five separately chartered Subsidiary Banks within our 
holding company structure also allows us to work with customers to maximize their FDIC deposit insurance levels and 
provide additional levels of insured deposits.    
Other Borrowed Funds 
 
Other borrowed funds include FHLB borrowings which are long-term borrowings issued by the FHLB of Dallas 
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, 2024, other borrowed funds totaled $10,541,000, a decrease 
of 1.9% from $10,745,000 at December 31, 2023.

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. Deposits from persons and entities domiciled in Mexico comprise a stable portion of the deposit base of 
our Subsidiary Banks.  Other important funding sources for our Subsidiary Banks during 2024 and 2023 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. 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. The following table summarizes our short-term borrowing 
capacities, net of balances outstanding:

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, 2024, 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 

17 
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, 2024, 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 15%, 15%, 15%, 
and 20%, respectively, for the first 12-month period projected. At December 31, 2024, 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 -3.51%, -6.57%, -9.22%, -11.67% +3.32%, +6.5%, 
+9.63% and +12.76%, 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 18 of the Notes to Consolidated Financial Statements. At December 31, 2024, the 
aggregate amount legally available to be distributed to us from our Subsidiary Banks as dividends was approximately 
$1,440,000,000, assuming that each Subsidiary Bank continues to be classified as “well capitalized” under the applicable 
regulations in effect at December 31, 2024. The restricted capital (capital and surplus) of our Subsidiary Banks was 
approximately $1,454,738,000 as of December 31, 2024. The undivided profits of our Subsidiary Banks were 
approximately $1,998,355,000 as of December 31, 2024.  
At December 31, 2024, we had outstanding $10,541,000 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, 2024, shareholders’ equity was $2,796,707,000 compared to $2,447,774,000 at December 31, 2023, an 
increase of $348,933,000, or 14.3%. Shareholders’ equity increased primarily due to an increase in retained earnings. 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 23.06% and 22.39% and risk-weighted total capital ratios of 24.31% and 23.65% as of December 31, 2024 

18 
and 2023, respectively, which are well above the minimum regulatory requirements and exceed the well-capitalized ratios 
(see Note 18 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, 2024, 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 Current Expected Credit Losses 
(“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. The U.S. has targeted implementation of Basel IV to begin on July 1, 
2025, subject to a three-year transition period with full compliance expected by July 1, 2028. 
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, 2024 and December 31, 2023, the principal amount of debentures 
outstanding totaled $108,868,000.  
The Debentures are subordinated and junior in right of payment to all of our present and future senior indebtedness 
(as defined in the respective indentures) and are pari passu with one another. The interest rate payable on, and the payment 
terms of the Debentures are the same as the distribution rate and payment terms of the respective issues of Capital and 
Common Securities issued by the Trusts. We have fully and unconditionally guaranteed the obligations of each of the 
Trusts with respect to the Capital and Common Securities. We have the right, unless an Event of Default (as defined in the 
Indentures) has occurred and is continuing, to defer payment of interest on the Debentures for up to twenty consecutive 

19 
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, 2024 and December 31, 2023, the total $108,868,000 of the Capital 
Securities outstanding qualified as Tier 1 capital.

Critical Accounting Policies 
We have established various accounting policies which govern the application of accounting principles in the 
preparation of our consolidated financial statements. The significant accounting policies are described in the Notes to the 
Consolidated Financial Statements. Certain accounting policies involve significant subjective judgments and assumptions 
by management which have a material impact on the carrying value of certain assets and liabilities; management considers 
such accounting policies to be critical accounting policies. 
We consider our estimated ACL as a policy critical to the sound operations of our Subsidiary Banks. 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  

21 
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 U.S./Mexico 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 
the risk of repayment when market values deteriorate, the business experiences turnover in key management, the 
business is unable to attract or maintain stable occupancy levels, or the market experiences an exit of a specific 
business type that is significant to the local economy, such as a manufacturing plant. Our primary risk management 
tool is internal monitoring measured against internal concentration limits that are significantly lower than regulatory 
thresholds and are segmented by low-risk and high-risk characteristics, such as the borrower’s equity, cash flow 
coverage, and non-amortizing versus amortizing status, further disaggregated by the length of time to pay in full.  This 
monitoring is regularly reported to senior management and the board of directors.  Risk management practices also 
extend to managing the borrower’s relationship with us and are designed to recognize degradation in the borrower’s 
ability to repay under established terms well before the borrower may default.  Loan and deposit activity by the 
borrower is monitored on a frequent basis, which may prompt a change in risk classification.  Once a loan is moved 
to a more severe risk classification, the loan performance, and when applicable, a plan by the borrower to rectify 
issues are monitored and reviewed at least quarterly.  Additionally, our credit administration team, who is independent 
from the lending team, reviews a substantial portion of the commercial lending portfolio annually, which includes a 
significant portion of the commercial real estate loan portfolio given the current mix of loans in our portfolio. The 
table below summarizes the commercial real estate loan portfolio disaggregated by the type of real estate securing the 
credit as of December 31, 2024:

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. 
 

22 
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, (v) Watch List—Substandard, and (vi) Watch List—Doubtful. Loans placed 
in the Economic Monitoring or Special Review categories reflect our opinion that the loans have potential weaknesses that 
require monitoring on a more frequent basis. Credits in those categories 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. Loans placed in the Watch 
List—Pass category reflect our opinion that the credit contains weaknesses that represent a greater degree of risk, which 
warrants “extra attention.” Credits placed 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. 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. Those 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 under contractual terms. Furthermore, there is a possibility that we may 
sustain some future loss if such weaknesses are not corrected. Loans placed in the Watch List—Doubtful category have 
shown defined weaknesses and reflect our belief that it is likely, based on current information and events, that we will be 
unable to collect all principal and/or interest amounts contractually due. Loans placed in the Watch List—Doubtful 
category 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 category are aggregated, and the credits in the Watch List—Substandard category remain in their own segment. For 
loans classified as Watch List—Doubtful, management evaluates these credits in accordance FASB ASC Subtopic 326-20, 
“Financial Instruments – Credit Losses – Measured at Amortized Cost,” and, if deemed necessary, a specific reserve is 
allocated to the loan. The analysis of the specific reserve is based on a variety of factors, including the borrower’s ability 
to pay, the economic conditions impacting the borrower’s industry and any collateral deficiency.  If it is a collateral-
dependent loan, the net realizable fair value of collateral will be evaluated for any deficiencies. Substantially all of our 
loans evaluated as Watch List – Doubtful 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 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 and non-accruals, (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 

23 
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 20, 2024, the Board of Directors extended and increased the repurchase program to purchase up to $150 million 
of common stock during the 12-month period commencing on March 15, 2024. On February 18, 2025, 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, 2025 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 2024, 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 
purposes, including employee stock compensation plans. As of February 24, 2025, a total of 13,713,787 shares had been 
repurchased under all programs at a cost of $415,392,000. 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 
share repurchases for the quarter ended December 31, 2024.

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, 2024 and 2023, 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, 
2024, 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, 
2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended 
December 31, 2024, 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, 2024, 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 27, 2025 expressed an unqualified opinion on the 
effectiveness of the Company's internal control over financial reporting. 
Basis for Opinion 
These financial statements are the responsibility of the Company’s management. Our responsibility is to express 
an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with 
the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities 
laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. 
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan 
and perform the audits to obtain reasonable assurance about whether the financial statements are free of material 
misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material 
misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those 
risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial 
statements. Our audits also included evaluating the accounting principles used and significant estimates made by 
management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide 
a reasonable basis for our opinion. 
Critical Audit Matter 
 
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated 
financial statements that was communicated or required to be communicated to the audit committee and that: (1) relate to 
accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially 
challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our 
opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit 
matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. 
 
Allowance for Credit Losses 
 
As described in Note 4 of the consolidated financial statements, the Company established an allowance for 
credit losses totaling $156,537,000 as of December 31, 2024. 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 

28 
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.

(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 

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 
Notes to Consolidated Financial Statements (Continued) 
38 
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, 2024 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, 2024.  
Mortgage-backed securities held at December 31, 2024 and 2023 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, 2024 and December 31, 2023 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.  

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 
Notes to Consolidated Financial Statements (Continued) 
39 
Our management continually reviews the ACL of the Subsidiary Banks using the amounts determined from the 
estimates established on specific doubtful loans, the estimate established on quantitative historical loss percentages, and 
the estimate based on qualitative current conditions and reasonable and supportable two-year forecasted data. Our 
methodology reverts to the average lifetime loss-rate beyond the forecast period when we can no longer develop reasonable 
and supportable forecasts. Should any of the factors considered by management in evaluating the adequacy of the estimate 
for current expected credit losses change, our estimate of current expected credit losses could also change, which could 
affect the level of future credit loss expense. While the calculation of our ACL utilizes management’s best judgment and 
all information reasonably available, the adequacy of the ACL is dependent on a variety of factors beyond our control, 
including, among other things, the performance of the entire loan portfolio, the economy, government actions, changes in 
interest rates, and the view of regulatory authorities towards loan classifications.  We believe that the allowance for 
probable loan losses is adequate.  
The Subsidiary Banks charge-off that portion of any loan which management considers to represent a loss as well 
as that portion of any other loan which is classified as a “loss” by bank examiners. Commercial, financial, and agricultural 
or real estate loans are generally considered by management to represent a loss, in whole or part, (i) when an exposure 
beyond any collateral coverage is apparent, (ii) when no further collection of the portion of the loan so exposed is 
anticipated based on actual results, (iii) when the credit enhancements, if any, are not adequate, and (iv) when the 
borrower’s financial condition would indicate so. Generally, unsecured consumer loans are charged-off when 90 days past 
due. 
Loans 
Loans are reported at the principal balance outstanding, net of unearned discounts. Interest income on loans is 
reported on an accrual basis. Loan fees and costs associated with originating the loans are accreted or amortized over the 
life of the loan using the interest method. We originate mortgage loans that may subsequently be sold to an unaffiliated 
third party. The loans are not securitized and if sold, are sold without recourse. Loans held for sale are carried at cost and 
the principal amount outstanding is not significant to the consolidated financial statements. 
Doubtful Loans 
Doubtful loans are those loans where it is probable that all amounts due according to contractual terms of the loan 
agreement will not be collected. Doubtful loans are measured based on (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 
$28,193,000 and $26,728,000 at December 31, 2024 and 2023, 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 
$358,000 and $236,000 at December 31, 2024 and 2023, 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. Due 
to timing issues in the accounting by some of the non-financial companies in which we hold an investment, activity 
recorded to our books is recorded one quarter in arrears. 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, 2024 and 2023, 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, 2024, 2023, and 2022, 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 2021. 

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES

42 
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, 
2024, after completing goodwill testing, we have determined that no goodwill impairment exists. There were no changes 
in the carrying amount of goodwill for the years ended December 31, 2024 and December 31, 2023. 
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.  
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, banking. The chief operating decision maker (“CODM”) is our chief executive 
officer.  The operating information used by our CODM 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. Our Subsidiary Banks offer all products and services on the same basis and on the same 
terms and operate in the same regulatory environment.   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 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 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. The adoption of ASU 2023-02 did not 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 

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 
Notes to Consolidated Financial Statements (Continued) 
44 
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 did not 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 2023-07 is effective for fiscal years beginning after December 15, 2024.  
The adoption of ASU 2023-07 did not 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.   
 
In November 2024, the FASB issued Accounting Standards Update No. 2024-03, Income Statement – Reporting 
Comprehensive Income – Expense Disaggregation Disclosure (Subtopic 220:40):  Disaggregation of Income Statement 
Expenses.  ASU 2024-03 requires new tabular disclosures of certain prescribed income statement expenses, including 
among other things, employee compensation and depreciation.  Additionally, ASU 2024-03 requires disclosure of selling 
expenses based upon an entity’s own definition.  The provisions of ASU 2024-03 are effective for annual periods beginning 
after December 15, 2026 and interim periods beginning after December 15, 2027.  The adoption of ASU 2024-03 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, 2024 and 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 period. Unrealized gains and losses related to equity securities with 
readily determinable fair values are included in net income.  
The amortized cost and estimated fair value by type of investment security at December 31, 2024 are as follows:

Included in the carrying value of residential mortgage- backed securities are $959,421 of mortgage-backed securities issued by Ginnie Mae, 
$3,700,678 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 
$1,896,183,000 and $1,646,971,000, respectively, at December 31, 2024. 
Proceeds from the sale and call of securities available-for-sale were $3,750,000, $2,045,000, and $800,000 during 
2024, 2023 and 2022, respectively, which amounts included $0, $0 and $0 of mortgage-backed securities. Gross gains of 
$0, $0 and $0, and gross losses of $1,000, $3,000 and $0 were realized on the sales and calls in 2024, 2023 and 2022, 
respectively. 
Gross unrealized losses on investment securities and the fair value of the related securities, aggregated by

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, 2024 and December 31, 2023, the balance in equity securities with readily determinable fair values 
recorded at fair value were $5,394,000 and $5,417,000, respectively. The following is a summary of unrealized and

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 $186,369,000 at December 31, 2024 and 
$200,245,000 at December 31, 2023 and are included in other investments on the consolidated financial statements. 
Unfunded commitments to LIHTC projects totaled $25,064,000 at December 31, 2024 and $34,126,000 at December 31, 
2023 and are included in other liabilities on the consolidated financial statements. Tax credits and other tax benefits, as 
well as amortization expense associated with investments in qualified low-income housing partnerships, are accounted for 
using the proportional amortization method of accounting.  There was a total of $28,310,000 in estimated tax credits related 
to these investments recorded for the twelve months ended December 31, 2024 and $26,615,000 in estimated amortization 
related to these investments for the twelve months ended December 31, 2024.  There were no impairment losses recorded 
on tax equity investments during the twelve months ended December 31, 2024.

(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.  
 
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.  
  
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 U.S. 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 
the risk of repayment when market values deteriorate, the business experiences turnover in key management, the 
business is unable to attract or maintain stable occupancy levels, or the market experiences an exit of a specific 
business type that is significant to the local economy, such as a manufacturing plant. Our primary risk management 
tool is internal monitoring measured against internal concentration limits that are significantly lower than regulatory 
thresholds and are segmented by low-risk and high-risk characteristics, such as the borrower’s equity, cash flow 
coverage, and non-amortizing versus amortizing status, further disaggregated by the length of time to pay in full.  This 
monitoring is regularly reported to senior management and the board of directors.  Risk management practices also 
extend to managing the borrower’s relationship with us and are designed to recognize degradation in the borrower’s 
ability to repay under established terms well before the borrower may default.  Loan and deposit activity by the 
borrower is monitored on a frequent basis, which may prompt a change in risk classification.  Once a loan is moved 
to a more severe risk classification, the loan performance, and when applicable, a plan by the borrower to rectify 
issues are monitored and reviewed at least quarterly.  Additionally, our credit administration team, who is independent 
from the lending team, reviews a substantial portion of the commercial lending portfolio annually, which includes a 
significant portion of the commercial real estate loan portfolio given the current mix of loans in our portfolio.  The 
table below summarizes the commercial real estate loan portfolio disaggregated by the type of real estate securing the 
credit as of December 31, 2024:

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

Notes to Consolidated Financial Statements (Continued)

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, (v) Watch List—Substandard, and (vi) Watch List—Doubtful. Loans placed 
in the Economic Monitoring or Special Review categories reflect our opinion that the loans have potential weaknesses that 
require monitoring on a more frequent basis. Credits in those categories 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. Loans placed in the Watch 
List—Pass category reflect our opinion that the credit contains weaknesses that represent a greater degree of risk, which 
warrants “extra attention.” Credits placed 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. 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. Those 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 under contractual terms. Furthermore, there is a possibility that we may 
sustain some future loss if such weaknesses are not corrected. Loans placed in the Watch List—Doubtful category have 
shown defined weaknesses and reflect our belief that it is likely, based on current information and events, that we will be 
unable to collect all principal and/or interest amounts contractually due. Loans placed in the Watch List—Doubtful 
category 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 category are aggregated, and the credits in the Watch List—Substandard category remain in their own segment. For 
loans classified as Watch List—Doubtful, management evaluates these credits in accordance FASB ASC Subtopic 326-20, 
“Financial Instruments – Credit Losses – Measured at Amortized Cost,” and, if deemed necessary, a specific reserve is 
allocated to the loan. The analysis of the specific reserve is based on a variety of factors, including the borrower’s ability 
to pay, the economic conditions impacting the borrower’s industry and any collateral deficiency.  If it is a collateral-
dependent loan, the net realizable fair value of collateral will be evaluated for any deficiencies. Substantially all of our 
loans evaluated as Watch List – Doubtful 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 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 and non-accruals, (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. 
A summary of the changes in the allowance for probable loan losses by loan class is as follows:

The ACL 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 increase 
in losses charged to the ACL for the year ended December 31, 2024 in the Commercial category can be attributed to a 
charge-down on one loan secured primarily by equipment and pipeline infrastructure used in the oil and gas industry.  The 
credit has been classified as Watch-List Doubtful since the end of 2022 at which time, and going forward, we have 
evaluated our loss exposure and adjusted reserves accordingly.  We also continued to attempt to work with our customer 
during that period; however, those negotiations came to a halt late in the third quarter of 2023 when the customer declared 
bankruptcy.  In March 2024, the bankruptcy court awarded the winning bid at foreclosure for the assets collateralizing the 
loan to a principal owner of the business.  The bid was not for the full carrying value of the loan and resulted in a charge-
down of approximately $25.6 million.  The pool specific qualitative loss factors management deemed appropriate for the 
ACL calculation at December 31, 2023 remained constant in the December 31, 2024 calculation.

The increase in Commercial loans individually evaluated for impairment at December 31, 2024 compared to 
December 31, 2023 can be attributed to two loans secured by commercial properties that were placed on non-accrual in 
the fourth quarter of 2024.  The increase in commercial real estate: farmland & commercial loans individually evaluated 
for impairment at December 31, 2024 compared to December 31, 2023 can be attributed to one relationship secured by 
commercial buildings in which childcare centers are operated. The increase in Commercial real estate: multifamily loans 
can be attributed to two loans secured by apartments that were placed on non-accrual in the third quarter of 2024.  
Loans accounted for on a non-accrual basis at December 31, 2024, 2023 and 2022 amounted to $169,136,000, 
$47,170,000, and $51,648,000, respectively. The effect of such non-accrual loans reduced interest income by 
approximately $12,661,000, $6,614,000, and $116,000 for the years ended December 31, 2024, 2023, and 2022, 
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, 2024, 2023, and 2022 amounted to approximately $6,693,000, $5,597,000, and 
$6,132,000, 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. 

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES

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, 2024, we did not provide any material modifications under these circumstances to any 
borrower experiencing financial difficulty that would require disclosure.   
 
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, 2024 
and December 31, 2023, was adequate to absorb expected losses from loans in the portfolio at that date.

The increase in Commercial loans past due 60 - 89 days or greater at December 31, 2024 can be primarily 
attributed to two loans secured by commercial properties that were placed on non-accrual in the fourth quarter of 2024.  
The decrease in Commercial loans past due 90 days or greater at December 31, 2024 can be attributed to a loan secured 
by equipment and pipeline infrastructure used in the oil and gas industry and oil and gas production that was charged-
down in the first quarter of 2024.  The increase in Commercial real estate:  farmland and commercial loans past due 90 
days or greater at December 3, 2024 can be attributed to two loans, one is a hotel and one is a commercial building, both 
of which are on non-accrual at December 31, 2024.  The increase in Commercial real estate: multifamily loans at 
December 31, 2024 can be attributed to a loan secured by apartments that is on non-accrual at December 31, 2024.  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, 2024 compared to December 31, 2023 can 
be primarily attributable to a relationship secured by commercial property, which was downgraded in the fourth quarter of 
2024, offset by the charge-down of a loan secured by equipment and pipeline infrastructure used in the oil and gas industry 
and oil and gas production that was charged down in the first quarter of 2024, as previously discussed.  The increase in 
Special Review Commercial real estate: other construction and land development loans at December 31, 2024 compared 
to December 31, 2023 can be attributed to a loan secured by residential lots that was upgraded from Watch-List 
Substandard.  The decrease in Watch-List Substandard loans in the same category for the same period can be attributed to 
the upgrade to Special Review of the residential lot loan, as mentioned, and the reclassification of a loan securing a hotel

upon the completion of construction to the Commercial real estate: farmland & commercial category. The increase in 
Commercial real estate: multifamily loans can be primarily attributed to two loans secured by apartments that were placed 
on non-accrual in 2024.

Banks. The purchasers have agreed to resell to the Subsidiary Banks identical securities upon the maturities of the 
agreements. Securities sold under repurchase agreements were mortgage-backed securities and averaged $616,208,000 
and $469,152,000 during 2024 and 2023, respectively, and the maximum amount outstanding at any month end during 
2024 and 2023 was $713,772,000 and $544,418,000, respectively.

Long-term advances at December 31, 2024 and December 31, 2023 consisted of amortizing advances. Two amortizing advances are outstanding 
at December 31, 2024 in the amounts of $2,852,000 and $7,689,000 and mature in December 2033 and November 2033, respectively. The 
amortization on the amortizing long-term advances totals approximately $210,000, $215,000, $221,000, $227,000 and $233,000 for the years 
ending December 31, 2025, 2026, 2027, 2028 and December 31, 2029, respectively.  
(9) 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  

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 
Notes to Consolidated Financial Statements (Continued) 
61 
and Common Securities”) and invested the proceeds thereof in an equivalent amount of junior subordinated debentures 
(the “Debentures”) we issued. As of December 31, 2024 and December 31, 2023, the principal amount of debentures 
outstanding totaled $108,868,000, 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, 2024 and December 31, 2023, the total $108,868,000, respectively, of 
the Capital Securities outstanding qualified as Tier 1 capital.

On July 1, 2023, the interest rate index on the Capital and Common Securities transitioned from U.S.-dollar London Interbank Offered Rate 
(“LIBOR”) to the Three-Month CME Term Secured Overnight Financing rate (“SOFR”) with a 26-basis point spread adjustment.

The Capital Securities may be redeemed in whole or in part on any interest payment date after the Optional Redemption Date. 
 
(10) 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

(11) 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 $4,460,000, $4,011,000, and 
$4,300,000 were charged to income for the years ended December 31, 2024, 2023, and 2022, respectively. 
(12) 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.

(14) 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 

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 
Notes to Consolidated Financial Statements (Continued)

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, 2024, a total of 456,702 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, 2024 and 
December 31, 2023 is approximately $4,540,000 and $1,464,000, 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 $3,144,000, $918,000 and $546,000, respectively, for the twelve 
months ended December 31, 2024, 2023, and 2022. As of December 31, 2024, there was approximately $8,309,000 in 
unrecognized liability related to non-vested SARs granted under the plan that will be recognized over a weighted average 
period of 7.5 years. 
 
 
 
 
 
(15) 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. 
(16) 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 $6,669,000 
and $13,335,000 at December 31, 2024 and 2023, respectively.

(17) 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, 2024, 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, 2024, the maximum potential amount of future payments is approximately $147,435,000. At December 31, 
2024, the fair value of these guarantees is not significant. Unsecured letters of credit totaled approximately $23,334,000 
and $23,677,000 at December 31, 2024 and 2023, 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. 
(18) 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, 2024, the Subsidiary Banks could pay dividends of up to 
$1,440,000,000 without prior regulatory approval and without adversely affecting their “well-capitalized” status under 
regulatory capital rules in effect at December 31, 2024. 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 

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 
Notes to Consolidated Financial Statements (Continued) 
68 
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, 2024, 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, 2024, 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. The U.S. has targeted implementation of Basel IV to begin on July 1, 2025, subject to a three-year 
transition period with full compliance expected by July 1, 2028.

As of December 31, 2024, 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, 2024, the most recent notification from the FDIC categorized all the Subsidiary Banks as 
well-capitalized under the regulatory framework for prompt corrective action. To be categorized as “well capitalized,” we

(19) Fair Value 
ASC Topic 820, “Fair Value Measurements and Disclosures” (“ASC 820”) defines fair value, establishes a 
framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value 
measurements. ASC 820 applies to all financial instruments that are being measured and reported on a fair value basis. 
ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly 
transaction between market participants at the measurement date; it also establishes a fair value hierarchy that prioritizes 
the inputs used in valuation methodologies into the following three levels: 
• 
Level 1 Inputs—Unadjusted quoted prices in active markets for identical assets or liabilities. 
• 
Level 2 Inputs—Observable inputs other than Level 1 prices, such as quoted prices for similar assets or 
liabilities, quoted prices in markets that are not active; or other inputs that are observable or can be 
corroborated by observable market data for substantially the full term of the assets or liabilities. 
• 
Level 3 Inputs—Unobservable inputs that are supported by little or no market activity and that are significant 
to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose 
value is determined using pricing models, discounted cash flow methodologies, or other valuation techniques,

as well as instruments for which the determination of fair value requires significant management judgment 
or estimation. 
 
A description of the valuation methodologies used for instruments measured at fair value, as well as the general 
classification of such instruments pursuant to the valuation hierarchy is set forth below. 
The following table represents financial instruments reported on the consolidated statements of condition at their

For the years ended December 31, 2024 and December 31, 2023, 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.

Certain financial instruments are measured at fair value on a nonrecurring basis. They are not measured at fair 
value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is 
evidence of impairment).

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 tabular disclosures above include only those loans or other real estate owned that had a 
change in the provision for credit loss during the reporting period or for which a new specific provision for credit loss was 
established during the reporting period.  The fair value of Watch List—Doubtful loans is derived in accordance with FASB 
ASC Subtopic 326-10, “Financial Instruments – Credit Losses - Overall”. 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 allowance for credit 
losses (“ACL”). The fair value of the loan is based on the fair value of the collateral, as determined through either an 
appraisal or internal evaluation process. The basis for our appraisal and appraisal review process are applicable regulatory 
guidelines, including regulatory appraisal laws and the Uniform Standards of Professional Appraisal Practice, which are 
incorporated into our lending policy.  All collateral dependent loans are evaluated in accordance with our lending policy 
to assess if a third-party appraisal is required to be obtained as part of our credit underwriting and monitoring process.  
Collateral dependent loans that do not meet the requirements for a third-party appraisal are required to undergo an internal 
evaluation by our in-house independent appraisal staff.   
 
Our determination to either seek an appraisal or to perform an internal evaluation is performed by our credit 
quality committee, which analyzes the existing collateral values of the doubtful loans and identifies obsolete appraisals or

Notes to Consolidated Financial Statements (Continued) 
74 
internal evaluations. The credit quality 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.  The ultimate 
decision on the appropriate action is made by our independent credit administration team. A new appraisal is not required 
if an internal evaluation, as performed by our in-house independent appraisal staff, 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 analysis of the doubtful loan. 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.   
 
As of December 31, 2024, we had $168,621,000 of doubtful commercial collateral-dependent loans, of which 
$110,583,000 had an appraisal performed within the immediately preceding rolling twelve-month period, and of which $0 
had an internal evaluation performed within the immediately preceding rolling twelve-month period. As of December 31, 
2023, we had approximately $46,491,000 of doubtful commercial collateral-dependent loans, of which $1,272,000 had an 
appraisal performed within the immediately preceding rolling twelve-month period and of which $35,061,000 had an 
internal evaluation performed within the immediately preceding rolling twelve-month period.      
 
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, 2024, 2023, and 2022, we recorded 
approximately $2,228,000, $0, 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, 2024, 2023, and 2022, we recorded approximately 
$632,000, $2,538,000, and $1,627,000, 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, 2024 and 
December 31, 2023 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.  

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 
Notes to Consolidated Financial Statements (Continued) 
75 
For variable rate performing loans, the carrying amount approximates the fair value. For fixed rate performing 
loans, the fair value is calculated by discounting scheduled cash flows using current interest rates at which similar loans 
with similar terms would be made to borrowers of similar credit quality. Fixed rate performing loans are within Level 3 of 
the fair value hierarchy. At December 31, 2024 and December 31, 2023, the carrying amount of fixed rate performing 
loans was $1,216,156,000 and $1,199,347,000, respectively, and the estimated fair value was $1,154,862,000 and 
$1,073,892,000, 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, 
2024 and December 31, 2023. 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, 2024 and December 31, 2023, the carrying amount of time deposits was $2,899,543,000 and 
$2,425,177,000, respectively, and the estimated fair value was $2,895,245,000 and $2,428,681,000, 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, 2024 and December 31, 2023.  
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, 2024 and December 31, 2023. 
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, 2024 and December 31, 2023 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, 2024 and December 31, 2023, the carrying amount of the fixed-rate 
long-term FHLB borrowings was $10,541,000 and $10,745,000, respectively, and the estimated fair value was 
$10,541,000 and $10,745,000, 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 

INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES 
Notes to Consolidated Financial Statements (Continued) 
76 
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.
