It is not possible to foresee or identify all such factors. The Company makes no commitment to update any forward-looking statement, or to disclose any facts, events or circumstances after the date hereof that may affect the accuracy of any forward-looking statement, unless required by law. Overview The Company, which is headquartered in Laredo, Texas, with more than 200 facilities and more than 300 ATMs, provides banking services for commercial, consumer and international customers of South, Central and Southeast Texas and the State of Oklahoma. The Company is one of the largest independent commercial bank holding companies headquartered in Texas. The Company, through its bank subsidiaries, is in the business of gathering funds from various sources and investing those funds in order to earn a return. The Company either directly or through a bank subsidiary owns two insurance agencies, a broker/ dealer and a majority interest in an investment banking unit that owns a broker/dealer. The Company’s primary earnings come from the spread between the interest earned on interest-bearing assets and the interest paid on interest-bearing liabilities. In addition, the Company generates income from fees on products offered to commercial, consumer and international customers. A primary goal of the Company 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 a critical objective of the Company. A key measure of the performance of a banking institution is the return on average common equity (‘‘ROE’’). The Company’s ROE for the year ended December 31, 2005 was 17.97% as compared to 18.17% for the year ended December 31, 2004. The Company is very active in facilitating trade along the United States border with Mexico. The Company does a large amount of business with customers domiciled in Mexico. Deposits from persons and entities domiciled in Mexico comprise a large and stable portion of the deposit base of the Company’s bank subsidiaries. The Company also serves the growing Hispanic population through the Company’s facilities located throughout South, Central and Southeast Texas and the State of Oklahoma. Expense control is an essential element in the Company’s long-term profitability. As a result, one of the key ratios the Company monitors is the efficiency ratio, which is a measure of non-interest expense to net-interest income plus non-interest income. The Company’s efficiency ratio has been under 55% for each of the last five years, which the Company’s review indicates is better than average compared to its national peer group. The Company’s efficiency ratio has increased over the last few years because of the Company’s aggressive branch expansion which have added 30 branches during 2005 alone. During rapid expansion periods, the Company’s efficiency ratio will suffer but the long term benefits of the expansion should be realized in future periods and the benefits should positively impact the efficiency ratio in future periods. 3 During the fourth quarter of 2003, the Company reduced its assets by approximately $1 billion dollars in anticipation of the Local Financial Corporation (‘‘LFIN’’) acquisition. The Company also increased its overnight liquidity in the form of fed funds sold to prepare for the cash payment required as part of the transaction. On June 18, 2004, the Company completed its acquisition of LFIN. The Company paid consideration totaling approximately $276.6 million in cash and 2.11 million shares of Company stock. As a result of the strategic management of earning assets in anticipation of the LFIN acquisition, net interest income for the first, second and third quarters of 2004 was negatively affected.

Net income was positively impacted by $5,613,000, net of tax, of distributions received in the first and second quarter of 2005 from the January 2005 merger of the PULSE EFT Association with Discover Financial Services, a business unit of Morgan Stanley. Members of the PULSE EFT Association received these distributions based in part upon their volume of transactions through the PULSE network. Additionally, net income for 2003 was positively affected by gains recognized on bond sales, which were made to reposition a portion of the Company’s bond portfolio to realize the 4 equity that was eroding in the portfolio due to rapid principal repayments. The Company recorded losses on the portfolio of $118,000, net of tax in 2005 compared to gains of $5,775,000, net of tax in 2004 and $15,204,000 net of tax in 2003. Net income for 2005 and 2004 has been negatively affected by the aggressive de novo branching activity by the Company. The Company has added 30 new branches in 2005 and 17 branches in 2004. The new branches do not include the 52 branches the Company acquired as a result of the LFIN acquisition. The Company believes the branching activity is necessary to expand the Company’s footprint in its markets and build future value; however, the Company realizes that net income will be negatively affected in periods of rapid expansion because of the period it takes to make the branches profitable. Additionally, as part of the LFIN acquisition, the Company decided to exit certain national lending strategies that LFIN employed. As a result, the Company’s total loans have decreased from 2004 to 2005. During the fourth quarter of 2003, the Company reduced its assets by approximately $1 billion in anticipation of the LFIN acquisition. The Company also increased its overnight liquidity in the form of fed funds sold to prepare for the cash payment required as part of the transaction. On June 18, 2004, the Company completed its acquisition of LFIN. As a result of the strategic management of earning assets, net interest income for the first, second and third quarters of 2004 was negatively affected. 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 the Company’s largest source of revenue. Net interest income is affected by both changes in the level of interest rates and changes in the amount and composition of interest earning assets and interest bearing liabilities.

In 2005 and 2004, as short term interest rates began to increase, the Company accordingly increased interest rates on loans and deposits. 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 14.8% from 4.87% in 2004 to 5.59% in 2005, and the rates paid on average interest bearing liabilities increased 49.7% from 1.69% in 2004 to 2.53% in 2005. The yield on average interest earning assets decreased 5.6% from 5.16% in 2003 to 4.87% in 2004, and the rates paid on average interest bearing liabilities decreased 2.3% from 1.73% in 2003 to 1.69% in 2004. The Company’s yield on investment securities increased .34% from 2004 to 2005 during a period of numerous interest rate increases. The majority of the Company’s taxable investment securities are invested in mortgage backed securities and during rapid increases or reduction in interest rates, the yield on these securities do not re-price as quickly as the loans do. The following table analyzes the changes in net interest income during 2005 and 2004 and the relative effect of changes in interest rates and volumes for each major classification of interest earning assets and interest-bearing liabilities. Nonaccrual loans have been included in assets for the purpose of this analysis, which reduces the resulting yields: 2005 compared to 2004 Net increase (decrease) due to 2004 compared to 2003 Net increase (decrease) due to Volume(1) Rate(1) Total Volume(1) Rate(1) Total (Dollars in Thousands) (Dollars in Thousands) Interest earned on: Loans, net of unearned discounts: Domestic . . . . . . . . . . . . . . . . . . . . . $48,906 1,556 Foreign . . . . . . . . . . . . . . . . . . . . . . $51,539 1,370 $100,445 2,926 $74,455 (6) $(14,627) $ 59,828 (549) (543) Investment securities: Taxable . . . . . . . . . . . . . . . . . . . . . .

As part of its strategy to manage interest rate risk, the Company strives 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. Management can quickly change the Company’s interest rate position at any given point in time as market conditions dictate. Additionally, interest rate changes do not affect all categories of assets and liabilities equally or at the same time. Analytical techniques employed by the Company to supplement gap analysis include simulation analysis to quantify interest rate risk exposure. The gap analysis prepared by management is reviewed by the Investment Committee of the Company twice a year. The Investment Committee is comprised of certain senior managers of the various Company bank subsidiaries along with consultants. Management currently believes that the Company is properly positioned for interest rate changes; however, if management determines at any time that the Company is not properly positioned, it will strive to adjust the interest rate sensitive assets and liabilities in order to manage the effect of interest rate changes. At December 31, 2005, based on these simulations, a rate shift of 200 basis points in interest rates up or a rate shift of 100 basis points down will not vary earnings by more than 1 percent of projected 2006 net interest income. 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. The Company believes that it is properly positioned for a potential interest rate increase or decrease. Allowance for Possible Loan Loss The following table presents information concerning the aggregate amount of non-accrual, past due and restructured domestic loans; certain loans may be classified in one or more category: Loans accounted for on a non-accrual basis . . . . . . . . . Loans contractually past due ninety days or more as to interest or principal payments . . . . . . . . . . . . . . . . . Loans accounted for as ‘‘troubled debt restructuring’’ . . December 31, 2005 2004 2003 2002 2001 (Dollars in Thousands) $30,075 $30,773 $20,960 $3,649 $8,170 5,082 — 7,833 — 7,666 213 5,241 165 2,937 103 The allowance for possible loan losses decreased 4.4% to $77,796,000 at December 31, 2005 from $81,351,000 at December 31, 2004. The increase in non-accrual loans from 2003 to 2004 can be attributed to certain non-accrual loans acquired as a result of the LFIN acquisition. The following table presents information concerning the aggregate amount of non-accrual and past due foreign loans extended to persons or entities in foreign countries. Certain loans may be classified in one or more category: December 31, 2005 2004 2003 2002 2001 Loans accounted for on a non-accrual basis . . . . . . . . . . . . . . Loans contractually past due ninety days or more as to $12,946 (Dollars in Thousands) $13,741 $ 85 $254 $82 interest or principal payments . . . . . . . . . . . . . . . . . . . . . . 608 104 597 21 66 7 The gross income that would have been recorded during 2005 and 2004 on non-accrual and restructured loans in accordance with their original contract terms was $1,144,000 and $962,000 on domestic loans and $1,185,000 and $241,000 on foreign loans, respectively. The amount of interest income on such loans that was recognized in 2005 and 2004 was $252,000 and $195,000 on domestic loans and $46,000 and $41,000 for foreign loans, respectively. The non-accrual loan policy of the bank subsidiaries is to discontinue the accrual of interest on loans when management determines that it is probable that future interest accruals will be uncollectible. Interest income on non-accrual loans is recognized only to the extent payments are received or when, in management’s opinion, the creditor’s financial condition warrants reestablishment of interest accruals. Under special circumstances, a loan may be more than 90 days delinquent as to interest or principal and not be placed on non-accrual status. This situation generally results when a bank subsidiary has a borrower who is experiencing financial difficulties, but not to the extent that requires a restructuring of indebtedness. The majority of this category is composed of loans that are considered to be adequately secured and/or for which there has been a recent history of payments. When a loan is placed on non-accrual status, any interest accrued, not paid is reversed and charged to operations against interest income. Loan commitments, consisting of unused commitments to lend, letters of credit, credit card lines and other approved loans, that have not been funded, were $1,542,272,000 and $1,406,598,000 at December 31, 2005 and 2004, respectively. See Note 19 to the Consolidated Financial Statements.

The allowances are established through charges to operations in the form of provisions for possible loan losses. Loan losses or recoveries are charged or credited directly to the allowances. The decrease in the allowance for possible loan losses can be attributed to the decrease in total loans, which is the result of the strategies employed after the consummation of the LFIN acquisition. The bank subsidiaries 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. While management of the Company 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 allowance for possible loan losses can be made only on a subjective basis. It is the judgment of the Company’s management that the allowance for possible loan losses at December 31, 2005 was adequate to absorb probable losses from loans in the portfolio at that date.

Non-interest income for 2004 as compared to 2003 also increased due to the LFIN acquisition. Furthermore, the Company recorded investment securities losses of $181,000 in 2005 compared to gains of $8,884,000 for 2004 and gains of $23,390,000 in 2003. The gains in 2003 occurred due to a program to reposition a portion of the Company’s bond portfolio to realize the equity that was eroding in the portfolio due to rapid principal repayments, the result of which, in effect, accelerated future earnings. Other investment income was positively impacted by $4,000,000 of income recognized on investments held by the Company’s investment services unit. Non-banking service charges decreased in 2004 compared to 2003 due to the decrease in fees earned by the Company’s investment services unit. The increase in other income from 2005 to 2004 can be attributed primarily to a gain of $8,636,000 from a distribution resulting from the January 2005 merger of the PULSE EFT Association with Discover Financial Services, a business unit of Morgan Stanley. Members of the PULSE EFT Association received these distributions based in part upon their volume of transactions through the PULSE network.

This is achieved through maintaining optimum staffing levels, an effective budgeting process, and internal consolidation of bank functions. The increase in non-interest expense for the three years ended 2005 can be attributed primarily to the expanded operations of the Company’s bank subsidiaries, which added 30 branches in 2005 (including the acquisition of LFIN in June 2004, which added approximately 700 employees, 52 branches and $42,188,000 in identified intangible assets) and increased fees paid by the Company’s investment banking unit, the GulfStar Group, in 2003. 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.

The decline is the result of the Company’s strategy to reduce the exposure to certain loan categories that LFIN employed prior to the acquisition by the Company. LFIN had a national real estate group that loaned funds throughout the United States and after extensive review by the Company, the Company concluded the national real estate group goals were not consistent with the Company’s loan origination goals that emphasize risk, pricing and the desire to lend primarily in the markets that the Company occupies. International Operations On December 31, 2005, the Company had $281,947,000 (2.7% of total assets) in loans outstanding to borrowers domiciled in foreign countries. The loan policies of the Company’s bank subsidiaries generally require that loans to borrowers domiciled in foreign countries be primarily secured by assets located in the United States or have credit enhancements, in the form of guarantees, from significant United States corporations.

The Company relies primarily on its high quality customer service, sales programs and advertising to attract and retain these deposits. Deposits provide the primary source of funding for the Company’s 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, 2005 were $6,656,426,000, an increase of 1.3% from $6,571,104,000 at December 31, 2004. The increase in deposits from 2004 to 2005 is primarily the result of the Company’s internal sales programs to organically grow deposits. As a result of the LFIN acquisition, the Company strategically reduced certain deposit categories of LFIN such as brokered deposits and certain public fund deposits because of the high expense associated with this type of funding. The Company has not traditionally sought brokered deposits as a funding source and the Company has not aggressively pursued public fund deposits because of the lack of relationships in those deposit categories. Return on Equity and Assets Certain key ratios for the Company for the years ended December 31, 2005, 2004 and 2003 follows (Note 1): Years ended December 31, 2005 2004 2003 Percentage of net income to: Average shareholders’ equity . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Liquidity is afforded by access to financial markets and by holding appropriate amounts of liquid assets. The bank subsidiaries of the Company 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 the Company’s bank subsidiaries. Historically, the Mexico based deposits of the Company’s bank subsidiaries have been a stable source of funding. Such deposits comprised approximately 28%, 28% and 39% of the Company’s bank subsidiaries’ total deposits as of December 31, 2005, 2004 and 2003, respectively. The decline in the concentration of Mexico based deposits can be attributed to recent acquisitions, including LFIN, and the growth in the Company’s deposit base in Texas. Other important funding sources for the Company’s bank subsidiaries have been borrowings from the Federal Home Loan Bank (‘‘FHLB’’), securities sold under repurchase agreements and large certificates of deposit, requiring management to closely monitor its asset/liability mix in terms of both rate sensitivity and maturity distribution. Primary liquidity of the Company and its subsidiaries has been maintained by means of increased investment in shorter-term securities, certificates of deposit and repurchase agreements. As in the past, the Company will continue to monitor the volatility and cost of funds in an attempt to match maturities of rate-sensitive assets and liabilities, and respond accordingly to anticipated fluctuations in interest rates over reasonable periods of time. Asset/Liability Management The Company’s fund management policy has as its primary focus the measurement and management of the 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, 2005, 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 on the following page, the Company is liability-sensitive during the early time periods and is asset-sensitive in the longer periods. 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. 17 INTEREST RATE SENSITIVITY (Dollars in Thousands) December 31, 2005 3 Months or Less Over 3 Months to 1 Year Rate/Maturity Over 1 Year to 5 Years Over 5 Years Total (Dollars in Thousands) Rate sensitive assets Federal funds sold . . . . . . . . . . . .

Income simulation analysis also focuses on the variability of net interest income and net income, but without the limitations of gap analysis. In particular, the fundamental, but often unstated, assumption of the gap approach that every statement of condition item that can re-price will do so to the full extent of any movement in market interest rates is taken into consideration in income simulation analysis. Accordingly, income simulation analysis captures not only the potential of assets and liabilities to mature or re-price, but also the probability that they will do so. Moreover, income simulation analysis focuses on the relative sensitivities of these balance sheet items and projects their behavior over an extended period of time in a motion picture rather than snapshot fashion. Finally, income simulation analysis permits management to assess the probable effects on balance sheet items not only of changes in market interest rates, but also of proposed strategies for responding to such changes. The Company and many other institutions rely primarily upon income simulation analysis in measuring and managing exposure to interest rate risk. At December 31, 2005, based on these simulations, a rate shift of 200 basis points in interest rates up or 100 basis points down will not vary earnings by more than 1% of projected 2006 net interest income. The basis point shift in interest rates is a hypothetical rate scenario used to calibrate risk, and does not 18 necessarily represent management’s current view of future market developments. The Company believes that it is properly positioned for a potential rate increase or decrease. All the measurements of risk described above are made based upon the Company’s business mix and interest rate exposures at the particular point in time. The exposure changes continuously as a result of the Company’s ongoing business and its risk management initiatives. While management believes these measures provide a meaningful representation of the Company’s 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. Principal sources of liquidity and funding for the Company are dividends from subsidiaries and borrowed funds, with such funds being used to finance the Company’s cash flow requirements. The Company closely monitors the dividend restrictions and availability from the bank subsidiaries as disclosed in Note 20 to the Consolidated Financial Statements. At December 31, 2005, the aggregate amount legally available to be distributed to the Company from bank subsidiaries as dividends was approximately $169,500,000, assuming that each bank subsidiary continues to be classified as ‘‘well capitalized’’ under the applicable regulations and excluding certified surplus. Pursuant to Texas law, a Texas state bank’s lending limit is twenty-five percent of the bank’s capital and certified surplus. The board of directors of the bank determines how much surplus will be certified. Except to absorb losses in excess of undivided profits and uncertified surplus, certified surplus may not be reduced without the prior written approval of the Texas banking commissioner. The restricted capital (capital, surplus and certified surplus) of the bank subsidiaries was approximately $860,052,000 as of December 31, 2005. The undivided profits of the bank subsidiaries were approximately $523,759,000 as of December 31, 2005. At December 31, 2005, the Company has outstanding $1,870,075,000 in other borrowed funds and $236,391,000 in junior subordinated deferrable interest debentures. In addition to borrowed funds and dividends, the Company has a number of other available alternatives to finance the growth of its existing banks as well as future growth and expansion. The Company maintains an adequate level of capital as a margin of safety for its depositors and shareholders. At December 31, 2005, shareholders’ equity was $792,867,000 compared to $753,090,000 at December 31, 2004, an increase of $39,777,000, or 5.3%. Shareholders’ equity increased due to the retention of earnings offset by the payment of cash dividends and the decrease in accumulated other comprehensive income from 2004 to 2005. The accumulated other comprehensive income (loss) is not included in the calculation of regulatory capital ratios. During 1990, the Federal Reserve Board (‘‘FRB’’) adopted a minimum leverage ratio of 3% for the most highly rated bank holding companies and at least 4% to 5% for all other bank holding companies. The Company’s leverage ratio (defined as shareholders’ equity plus eligible trust preferred securities issued and outstanding less goodwill and certain other intangibles divided by average quarterly assets) was 7.26% at December 31, 2005 and 6.91% at December 31, 2004. The core deposit intangibles and goodwill of $328,486,000 as of December 31, 2005, recorded in connection with financial institution acquisitions of the Company after February 1992, are deducted from the sum of core capital elements when determining the capital ratios of the Company. The substantial increase in core deposit intangibles and goodwill and the resulting decrease in the Company’s leverage ratio can be attributed to the LFIN acquisition. The FRB has adopted risk-based capital guidelines which assign risk weightings to assets and off-balance sheet items. The guidelines also define and set minimum capital requirements (risk-based capital ratios). Under the final 1992 rules, all banks are required to have Tier 1 capital of at least 4.0% of risk-weighted assets and total capital of 8.0% of risk-weighted assets. Tier 1 capital consists principally of shareholders’ equity plus trust preferred securities issued and outstanding less goodwill and certain other intangibles, while total capital consists of Tier 1 capital, certain debt instruments and a portion of the reserve for loan losses. In order to be deemed well capitalized pursuant to the regulations, an institution must have a total risk-weighted capital ratio of 10%, a Tier 1 risk-weighted ratio of 6% and a Tier 1 leverage ratio of 5%. The Company had risk-weighted Tier 1 capital ratios of 12.97% and 10.74% and risk 19 weighted total capital ratios of 14.22% and 11.99% as of December 31, 2005 and 2004, respectively, which are well above the minimum regulatory requirements and exceed the well capitalized ratios (see note 20 to notes to Consolidated Financial Statements). During the past few years the Company has expanded its banking facilities. Among the activities and commitments the Company funded during 2005 and 2004 were certain capital expenditures relating to the modernization and improvement of several existing bank facilities and the expansion of the bank branch network. Junior Subordinated Deferrable Interest Debentures The Company has formed eight statutory business trusts under the laws of the State of Delaware, for the purpose of issuing trust preferred securities. As part of the LFIN acquisition, the Company acquired three additional statutory business trusts previously formed by LFIN for the purpose of issuing trust preferred securities. The eight statutory business trusts formed by the Company and the three business trusts acquired in the LFIN transaction (the ‘‘Trusts’’) have each issued Capital and Common Securities and invested the proceeds thereof in an equivalent amount of junior subordinated debentures (the ‘‘Debentures’’) issued by the Company or LFIN, as appropriate. The Company has succeeded to the obligations of LFIN under the LFIN Debentures, which have an outstanding principal balance of $62,115,000 as of December 31, 2005. The Debentures will mature on various dates; however the Debentures may be redeemed at specified prepayment prices, in whole or in part after the optional redemption dates specified in the respective indentures or in whole upon the occurrence of any one of certain legal, regulatory or tax events specified in respective indentures. As of December 31, 2005, the principal amount of debentures outstanding totaled $236,391,000. The Debentures are subordinated and junior in right of payment to all present and future senior indebtedness (as defined in the respective indentures) of the Company, 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. The Company has fully and unconditionally guaranteed the obligations of each of the Trusts with respect to the Capital and Common Securities. The Company has 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 ten consecutive semi-annual periods on Trusts I through IV and LFIN Trust II and for up to twenty consecutive quarterly periods on Trusts V through VIII and LFIN Trusts I and III. 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 of the Company 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. For December 31, 2005, the total $236,391,000 of the Capital Securities outstanding qualified as Tier 1 capital. In March 2005, the Federal Reserve Board issued a final rule that would continue to allow the inclusion of trust preferred securities in Tier 1 capital, but with stricter quantitative limits. Under the final rule, after a five-year transition period ending March 31, 2009, the aggregate amount of trust preferred securities and certain other capital elements would be limited to 25% of Tier 1 capital elements, net of goodwill, less any associated deferred tax liability. The amount of trust preferred securities and certain other elements in excess of the limit could be included in Tier 2 capital, subject to restrictions. Bank holding companies with significant international operations will be expected to limit trust preferred 20 securities to 15% of Tier 1 capital elements, net of goodwill; however, they may include qualifying mandatory convertible preferred securities up to the 25% limit. After the transition period, the Company believes that the majority of the $236,391,000 of Capital Securities will qualify as Tier 1 capital.

The significant accounting policies are described in the footnotes 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. The Company considers its Allowance for Possible Loan Losses as a policy critical to the sound operations of the bank subsidiaries and the Company also considers accounting policies related to stock- based compensation to be critical due to the evolving nature of options; however, these policies involve considerable subjective judgment and estimation by management and therefore could impact the Company’s consolidated financial statements. The allowance for possible loan losses consists of the aggregate loan loss allowances of the bank subsidiaries. The allowances are established through charges to operations in the form of provisions for possible loan losses. Loan losses or recoveries are charged or credited directly to the allowances. The allowance for possible loan losses of each bank subsidiary is maintained at a level considered appropriate by management, based on estimated probable losses in the loan portfolio. The allowance is derived from the following elements: (i) allowances established on specific loans and (ii) allowances based on historical loss experience on the Company’s remaining loan portfolio, which includes general economic conditions and other qualitative risk factors both internal and external to the Company. See also discussion regarding the allowance for possible loan losses and provision for possible loan losses included in ‘‘Allowance for Possible Loan Loss’’ included in ‘‘Results of Operations’’ on page 7 and ‘‘Provision and Allowance for Possible Loan Losses’’ included in Notes 1 and 5 of the Notes to Consolidated Financial Statements for further information regarding the Company’s provision and allowance for possible loan losses policy. The specific loan loss provision is determined using the following methods. On a weekly basis, loan past due reports are reviewed by the servicing loan officer to determine if a loan has any potential problem and if a loan should be placed on the Company’s internal classified report. Additionally, the Company’s credit department reviews the majority of the loans 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, any analysis on loans that is provided through examinations by regulatory authorities is considered in the review process. After the above analysis is completed, the Company will determine if a loan should be placed on an internal classified report because of issues related to the analysis of the credit, credit documents, collateral and/or payment history. The Company’s internal classified report is segregated into the following categories: (i) ‘‘Pass Credits,’’ (ii) ‘‘Special Review Credits,’’ (iii) ‘‘Watch List Credits-Pass Credits,’’ or (iv) ‘‘Watch List Credits- Substandard and Doubtful Credits.’’ The loans placed in the ‘‘Pass Credits’’ category reflect the Company’s opinion that the loan conforms to the bank’s lending policies, which includes the borrower’s ability to repay, the value of the underlying collateral, if any, as it relates to the outstanding indebtedness of the loan, and the economic environment and industry in which the borrower operates. The loans placed in the ‘‘Special Review Credits’’ or the ‘‘Watch List Credits-Pass Credits’’ category reflect the Company’s opinion that the loans reflect potential weakness which require monitoring on a more frequent basis; however, the ‘‘Special Review Credits’’ or the ‘‘Watch List Credits-Pass Credits’’ are not considered to need a specific reserve at the time, but 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 Credits-Substandard and Doubtful Credits’’ category reflect the Company’s opinion that the loans contain clearly pronounced credit weaknesses and/or inherent financial weaknesses of the borrower. Credits classified as ‘‘Watch List Credits-Substandard and Doubtful Credits’’ are potentially evaluated under 22 Statement of Financial Accounting Standards No. 114, ‘‘Accounting by Creditors for Impairment of a Loan,’’ criteria and, if deemed necessary a specific reserve is allocated to the credit. The specific reserve allocated under SFAS No. 114, is based on (1) the present value of expected future cash flows discounted at the loan’s effective interest rate; (2) the loan’s observable market price; or (3) the fair value of the collateral if the loan is collateral dependent. Substantially all of the Company’s loans evaluated under SFAS No. 114 are measured using the fair value of collateral method. In limited cases, the Company may use other methods to determine the specific reserve of a loan under SFAS No. 114 if such loan is not collateral dependent. The allowance, based on historical loss experience on the Company’s remaining loan portfolio, which includes the ‘‘Pass Credits,’’ ‘‘Special Review Credits,’’ ‘‘Watch List Credits-Pass Credits,’’ and ‘‘Watch List Credits-Substandard and Doubtful Credits’’ is determined by segregating the remaining loan portfolio into certain categories such as commercial loans, installment loans, international loans, loan concentrations and overdrafts. Installment loans are then further segregated by number of days past due. A historical loss percentage, adjusted for (i) management’s evaluation of changes in lending policies and procedures, (ii) current economic conditions in the market area served by the Company, (iii) other risk factors, (iv) the effectiveness of the internal loan review function, (v) changes in loan portfolios, and (vi) the composition and concentration of credit volume is applied to each category. Each category is then added together to determine the allowance allocated under Statement of Financial Accounting Standards No. 5. The Company’s management continually reviews the allowance for loan loss of the bank subsidiaries using the amounts determined from the allowances established on specific loans, the allowance established based on historical percentages and the loans charged off and recoveries to establish an appropriate amount to maintain in the Company’s allowance for loan loss. If the bases of the Company’s assumptions change, the allowance for loan loss would either decrease or increase and the Company would increase or decrease the provision for loan loss charged to operations accordingly. The Company accounts for stock-based employee compensation plans based on the intrinsic value method provided in Accounting Principles Board Opinion No. 25 ‘‘Accounting for Stock Issued to Employees,’’ (‘‘APB No. 25’’), and related interpretations. Because the exercise price of the Company’s employee stock options equals the market price of the underlying stock on the measurement date, which is generally the date of grant, no compensation expense is recognized on options granted. Compensation expense for stock awards is based on the market price of the stock on the measurement date, which is generally the date of grant, and is recognized ratably over the service period of the award. Statement of Financial Accounting Standards No. 123 (‘‘SFAS No. 123’’), ‘‘Accounting for Stock- Based Compensation,’’ as amended by Statement of Financial Accounting Standards No. 148 (‘‘SFAS No. 148’’), ‘‘Accounting for Stock-Based Compensation—Transition and Disclosure, an amendment of FASB Statement No. 123,’’ requires pro forma disclosures of net income and earnings per share for companies not adopting its fair value accounting method for stock-based employee compensation. The pro forma disclosures presented in Note 1 in the accompanying Notes to Consolidated Financial Statements included elsewhere in this report use the fair value method of SFAS No. 123 to measure compensation expense for stock-based employee compensation plans. The fair value of stock options granted was estimated as the measurement date, which is generally the date of grant, using the Black-Sholes-Merton option-pricing model. This model was developed for use in estimating the fair value of publicly traded options that have no vesting restrictions and are fully transferable. Additionally, the model requires the input of highly subjective assumptions. Because the Company’s employee stock options have characteristics significantly different from those of publicly traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the Black-Sholes- Merton option-pricing model does not necessarily provide a reliable single measure of the fair value of the Company’s stock options. 23 In December 2004, the Financial Accounting Standards Board (‘‘FASB’’) issued Statement of Financial Accounting Standards No. 123R (‘‘SFAS No. 123R’’), ‘‘Share-Based Payment (Revised 2004).’’ Among other things, SFAS No. 123R eliminates the ability to account for stock-based compensation using APB No. 25 and requires that such transactions be recognized as compensation cost in the income statement based on their fair values on the date of the grant. SFAS No. 123R is effective for the Company on January 1, 2006. Based on the stock-based compensation awards outstanding as of December 31, 2005 for which the requisite service is not expected to be fully rendered prior to January 1, 2006, the Company expects to recognize additional pre-tax quarterly compensation cost of $229,000 beginning in the first quarter of 2006 as a result of the adoption of SFAS No. 123R. Future levels of compensation cost recognized related to stock-based compensation awards (including the aforementioned expected costs during the period of adoption) may be impacted by new awards and/or modifications, repurchases and cancellations of existing awards before and after the adoption of SFAS No. 123R.

Stock Repurchase Program The Company expanded its formal stock repurchase program on November 17, 2005. Under the expanded stock repurchase program, the Company is authorized to repurchase up to $175,000,000 of its Common Stock through December 31, 2006. Stock repurchases may be made from time to time on the open market or through private transactions. Shares repurchased in this program will be held in treasury for reissue for various corporate purposes, including employee stock option plans. As of March 7, 2006, a total of 4,388,693 shares had been repurchased under this program at a cost of $165,763,000. Stock repurchases are reviewed quarterly at the Company’s Board of Directors meetings, and the Board of Directors has stated that the aggregate investment in treasury stock should not exceed $195,973,000. In the past, the Board of Directors has increased previous caps on treasury stock once they were met, but there are no assurances that an increase of the $195,973,000 cap will occur in the future. As of March 7, 2006, the Company has approximately $186,736,000 invested in treasury shares, which amount has been accumulated since the inception of the Company. Share repurchases are only conducted under publicly announced repurchase programs approved by the Board of Directors.

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of International Bancshares Corporation and subsidiaries as of December 31, 2005 and 2004, and the results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2005, in conformity with U.S. generally accepted accounting principles. As discussed in note 1 to the consolidated financial statements, effective December 31, 2003, the Company changed the method of accounting for its investment in its statutory business trusts. We also have audited in accordance with the standards of the Public Company Accounting Oversight Board (United States), the effectiveness of International Bancshares Corporation and subsidiaries’ internal control over financial reporting as of December 31, 2005, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated March 15, 2006, expressed an unqualified opinion on management’s assessment of, and the effective operation of, internal control over financial reporting. /s/ KPMG LLP San Antonio, Texas March 15, 2006 27 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Consolidated Statements of Condition December 31, 2005 and 2004 (Dollars in Thousands, Except Per Share Amounts) Assets Cash and due from banks . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The following is a description of the more significant of those policies. Consolidation and Basis of Presentation The consolidated financial statements include the accounts of the Corporation and its wholly-owned bank subsidiaries, International Bank of Commerce, Laredo (‘‘IBC’’), Commerce Bank, International Bank of Commerce, Zapata, International Bank of Commerce, Brownsville, and the Corporation’s wholly- owned non-bank subsidiaries, IBC Subsidiary Corporation, IBC Life Insurance Company, IBC Trading Company and IBC Capital Corporation. All significant inter-company balances and transactions have been eliminated in consolidation. The Company early adopted the provisions of FIN 46R as of December 31, 2003 and deconsolidated its investment in eight statutory business trusts formed for the purpose of issuing trust preferred securities. Three statutory business trusts that were acquired in the Company’s acquisition of Local Financial Corporation were also deconsolidated under the provisions of FIN 46R. The Company, through its subsidiaries, is 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. The primary markets of the Company are South, Central, and Southeast Texas and the state of Oklahoma. Each bank subsidiary is very active in facilitating international trade along the United States border with Mexico and elsewhere. Although the Company’s loan portfolio is diversified, the ability of the Company’s debtors to honor their contracts is primarily dependent upon the economic conditions in the Company’s trade area. In addition, the investment portfolio is directly impacted by fluctuations in market interest rates. The Company and its bank subsidiaries are subject to the regulations of certain Federal agencies as well as the Texas 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. The preparation of the consolidated financial statements in conformity with accounting policies 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 possible loan losses. Per Share Data All share and per share information has been restated giving retroactive effect to stock dividends distributed. Investment Securities The Company classifies debt and equity 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 classified as ‘‘held-to-maturity’’ are carried at amortized cost for financial statement reporting, while securities classified as ‘‘available-for-sale’’ and ‘‘trading’’ are carried at their fair 36 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (1) Summary of Significant Accounting Policies (Continued) value. Unrealized holding gains and losses are included in net income for those securities classified as ‘‘trading’’, while unrealized holding gains and losses related to those securities classified as ‘‘available-for-sale’’ are excluded from net income and reported net of tax as other comprehensive income and in shareholders’ equity as accumulated other comprehensive income until realized. The Company did not maintain any trading securities during the three year period ended December 31, 2005. Mortgage-backed securities held at December 31, 2005 and 2004 represent participating interests in pools of long-term first mortgage loans originated and serviced by the issuers of the securities. Premiums and discounts are amortized using the straight-line method over the contractual maturity of the loans adjusted for anticipated prepayments. Income recognized under the straight-line method is not materially different from income that would be recognized under the level yield or ‘‘interest method’’. Mortgage- backed securities are either issued or guaranteed by the U.S. Government or its agencies. Market interest rate fluctuations can affect the prepayment speed of principal and the yield on the security. Unearned Discounts Consumer loans are frequently made on a discount basis. The amount of the discount is subsequently included in interest income ratably over the term of the related loans to approximate the effective interest method. Provision and Allowance for Possible Loan Losses The allowance for possible loan losses is maintained at a level considered adequate by management to provide for probable loan losses. The allowance is increased by provisions charged to operating expense and reduced by net charge-offs. The provision for possible loan losses is the amount, which, in the judgment of management, is necessary to establish the allowance for probable loan losses at a level that is adequate to absorb known and inherent risks in the loan portfolio. Management believes that the allowance for possible loan losses is adequate. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Company’s bank subsidiaries’ allowances for possible loan losses. Such agencies may require the Company’s bank subsidiaries to recognize additions or reductions to their allowances based on their judgments of information available to them at the time of their examination. 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 amortized over the life of the loan. Non-Accrual Loans The non-accrual loan policy of the Company’s bank subsidiaries is to discontinue the accrual of interest on loans when management determines that it is probable that future interest accruals will be un-collectible. Interest income on non-accrual loans is recognized only to the extent payments are received 37 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (1) Summary of Significant Accounting Policies (Continued) or when, in management’s opinion, the debtor’s financial condition warrants reestablishment of interest accruals. Other Real Estate Owned 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 allowance for loan possible losses, if necessary. Any subsequent write-downs are charged against other non-interest expense. Operating expenses of such properties and gains and losses on their disposition are included in other non-interest expense. 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. 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. The Company files a consolidated federal income tax return with its subsidiaries. Recognition of deferred tax assets is based on management’s belief that the benefit related to certain temporary differences, tax operating loss carryforwards, 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. Stock Options In December 2002, the Financial Accounting Standards Board (‘‘FASB’’) issued Statement of Financial Accounting Standards No. 148 (‘‘SFAS No. 148’’), ‘‘Accounting for Stock-Based Compensation— Transition and Disclosure, an amendment of FASB Statement No. 123.’’ SFAS No. 148 amends Statement ‘‘Accounting for Stock-Based of Financial Accounting Standards No. 123 (‘‘SFAS No. 123’’), Compensation,’’ to provide alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation. In addition, SFAS No. 148 amends the disclosure requirement of SFAS No. 123 to require prominent disclosures in both annual and interim financial statements about the fair value based method of accounting for stock-based employee compensation for those companies that have elected to continue to apply Accounting Principles Board Opinion No. 25 (‘‘APB 25’’), ‘‘Accounting for Stock Issued to Employees.’’ In December 2004, the FASB issued Statement of Financial Accounting Standards No. 123R (‘‘SFAS No. 123R’’), ‘‘Share-Based Payment (Revised 2004).’’ SFAS 123R eliminates the ability to account for stock-based compensation using APB 25 and requires that such transactions be recognized as compensation expense in the consolidated statement 38 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (1) Summary of Significant Accounting Policies (Continued) of income based on their fair values on the date of the grant. The Company adopted the provisions of SFAS No. 123R on January 1, 2006. Based on the stock-based compensation awards outstanding as of December 31, 2005 for which the requisite service is not expected to be fully rendered prior to January 1, 2006, the Company expects to recognize additional pre-tax quarterly compensation cost of $229,000 beginning in the first quarter of 2006 as a result of the adoption of SFAS No. 123R. Future levels of compensation cost recognized related to stock-based compensation awards (including the aforementioned expected costs during the period of adoption) may be impacted by new awards and/or modifications, repurchases and cancellations of existing awards before and after the adoption of SFAS No. 123R. At December 31, 2005, the Company had one stock-based employee compensation plan and certain options granted outside the plan. The Company accounts for options under the recognition and measurement principles of APB 25, and related interpretations. No stock-based employee cost is reflected in net income, as all options granted had an exercise price equal to the market value of the underlying common stock on the date of grant. The following table, as prescribed by SFAS No. 148, illustrates the effect on net income and earnings per share if the Company had applied the fair value recognition provisions of SFAS No. 123 to stock based employee compensation.

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. Prior to 2002, goodwill was amortized over its estimated useful life using the straight-line method or an accelerated basis (as appropriate) over periods generally not exceeding 25 years. On January 1, 2002, in accordance with a 39 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (1) Summary of Significant Accounting Policies (Continued) new accounting standard, the Company stopped amortizing goodwill and adopted a new policy for measuring goodwill for impairment. Under the new policy, goodwill is assigned to reporting units. Goodwill is then tested for impairment at least annually or on an interim basis if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit below its carrying value. 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. The Company’s identified intangible assets relate to core deposits. Identified intangible assets with definite useful lives are amortized on an accelerated basis over their estimated life. Identified intangible assets with indefinite useful lives are not amortized until their lives are determined to be definite. Identified intangible assets, premises and equipment and other long lived assets are tested for impairment whenever events or changes in circumstances indicate the carrying amount of the assets may not be recoverable from future undiscounted cash flow. If impaired, the assets are recorded at fair value. See Note 7—Goodwill and Other Intangible Assets. Impairment of Long-Lived Assets Long-lived assets, such as property, plant and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying value of the asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying value of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying value of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the statement of condition and reported at the lower of the carrying value or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections of the statement of condition. Consolidated Statements of Cash Flows For purposes of the consolidated statements of cash flows, the Company considers all short-term investments with a maturity at date of purchase of three months or less to be cash equivalents. Also, the Company reports transactions related to deposits with other financial institutions, customer time deposits and loans to customers on a net basis. Accounting for Transfers and Servicing of Financial Assets The Company accounts 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, the Company recognizes the financial and servicing assets it controls and liabilities it has incurred, derecognizes financial assets when control has been surrendered and derecognizes liabilities when extinguished. 40 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (1) Summary of Significant Accounting Policies (Continued) Segments of an Enterprise and Related Information The Company operates as one segment. The operating information used by the Company’s chief executive officer for purposes of assessing performance and making operating decisions about the Company is the consolidated financial statements presented in this report. The Company has four active operating subsidiaries, namely, the bank subsidiaries, otherwise known as International Bank of Commerce, Laredo, Commerce Bank, International Bank of Commerce, Zapata and International Bank of Commerce, Brownsville. The Company applies the provisions of SFAS No. 131, ‘‘Disclosures about Segments of an Enterprise and Related Information,’’ in determining its reportable segments and related disclosures. None of the Company’s other subsidiaries meets the 10% threshold for disclosure under SFAS No. 131. Derivative Instruments The Company currently does not directly engage in hedging activities and does not directly hold any derivative instruments or embedded derivatives. Guarantor’s Accounting and Disclosure Requirements for Guarantees In November 2002, the FASB issued FASB Interpretation No. 45 (‘‘FIN 45’’), ‘‘Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others, an interpretation of FASB Statements No. 5, 57 and 107 and rescission of FASB Interpretation No. 34.’’ FIN 45 elaborates on the disclosures to be made by a guarantor in its interim and annual financial statements about its obligations under certain guarantees that it has issued. This Interpretation also incorporates, without change, the guidance in Financial Accounting Standards Board Interpretation No. 34 (‘‘FIN 34’’), ‘‘Disclosure of Indirect Guarantees of Indebtedness of Others,’’ which has been superceded. FIN 45 also clarifies that a guarantor is required to recognize, at the inception of a guarantee, a liability for the obligations it has undertaken in issuing the guarantee, including its ongoing obligations to stand ready to perform over the term of the guarantee in the event that the specified triggering events or conditions occur. The initial recognition and initial measurement provisions of FIN 45 were applicable on a prospective basis to guarantees issued or modified after December 31, 2002, irrespective of the guarantor’s fiscal year-end. The disclosure requirements were effective for financial statements of interim or annual periods ending after December 15, 2002, and are included in the notes to the Company’s consolidated financial statements. The adoption of FIN 45 did not have a significant impact on the Company’s consolidated financial statements. 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. New Accounting Standards In May 2005, The Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 154, (‘‘SFAS No. 154’’), ‘‘Accounting Changes and Error Corrections, a Replacement of APB Opinion No. 20 and FASB Statement No. 3.’’ SFAS No. 154 establishes, unless impracticable, retrospective application as the required method for reporting a change in accounting principle in the absence of explicit transitional requirements specific to a newly adopted accounting principle. Previously, 41 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (1) Summary of Significant Accounting Policies (Continued) most changes in accounting principle were recognized by reporting a cumulative change in accounting principle to the net income of the period of the change. Under SFAS No. 154, retrospective application requires that (i) the cumulative effect of the change to the new accounting principle on periods prior to those presented be reflected in the carrying amounts of asset and liabilities as of the beginning of the first period presented, (ii) an offsetting adjustment, if any, be made to the opening balance of retained earnings or other appropriate components of equity for that period, and (iii) financial statements for each prior period presented be adjusted to reflect the direct period specific effects of applying the new accounting principle. Special retroactive application rules apply in certain situations where it is impracticable to determine either the period specific effects or the cumulative effect of the change. Indirect effects of a change in accounting principle are required to be reported in the period in which the accounting change is made. SFAS No. 154 carries forward the guidance in APB Opinion No. 20 ‘‘Accounting Changes,’’ requiring justification of a change in accounting principle on the basis of preferability. SFAS No. 154 also carries forward, without change, the guidance in APB Opinion 20, for reporting the correction of an error in previously issued financial statements and for a change in accounting estimate. SFAS No. 154 is effective for accounting changes and corrections of errors made in fiscal years beginning after December 15, 2005. In November 2005, the Financial Accounting Standards Board issued FASB Staff Position No 115-1 (‘‘FSP 115-1’’), ‘‘The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments.’’ FSP 115-1 provides guidance for determining when an investment is considered impaired, whether impairment is other-than-temporary, and measurement of an impairment loss. An investment is considered impaired if the fair value of the investment is less than its cost. If, after consideration of all available evidence to evaluate the realizable value of its investment, impairment is determined to be other- thank-temporary, then an impairment loss should be recognized equal to the difference between the investments’ cost and its fair value. FSB 115-1 nullifies certain provision of Emerging Issues Task Force (‘‘EITF’’) Issue No 01-1, ‘‘The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments,’’ while retaining the disclosure requirements of EITF 01-1 which were adopted in 2003. FSP 115-1 is effective for reporting periods beginning after December 15, 2005. The adoption of this new standard at January 1, 2006 did not have an impact on the Company’s consolidated financial statements. In December 2004, the Financial Accounting Standards Board issued Statement of Financial Accounting Standards No. 123R, (‘‘SFAS No. 123R’’), ‘‘Share-Based Payment, an Amendment of Statements No. 123 and 95.’’ The revision to the existing SFAS No. 123 eliminates the ability of public companies to account for stock-based compensation using Accounting Principles Board Opinion No. 25 (‘‘APB 25’’), ‘‘Accounting for Stock Issues to Employees’’ and requires such transactions be recognized as compensation expense in the Company’s consolidated financial statements based on the fair value of the options issued as of their grant date. SFAS No. 123R was to be effective for the Company for interim and reporting periods after December 31, 2005. The Company adopted the provisions of SFAS No. 123R on January 1, 2006. Based on the stock-based compensation awards outstanding as of December 31, 2005 for which the requisite service is not expected to be fully rendered prior to January 1, 2006, the Company expects to recognize additional pre-tax quarterly compensation cost of $229,000 beginning in the first quarter of 2006 as a result of the adoption of SFAS No. 123R. Future levels of compensation cost recognized related to stock-based compensation awards (including the aforementioned expected costs during the period of adoption) may be impacted by new awards and/or modifications, repurchases and cancellations of existing awards before and after the adoption of SFAS No. 123R. 42 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (1) Summary of Significant Accounting Policies (Continued) In December 2003, the American Institute of Certified Public Accountants issued Statement of Position 03-3 (‘‘SOP 03-3’’), ‘‘Accounting for Certain Loans or Debt Securities Acquired in a Transfer.’’ SOP 03-3 addresses accounting for differences between the contractual cash flows of certain loans and debt securities and the cash flows expected to be collected when loans or debt securities are acquired in a transfer and those cash flow differences are attributable, at least in part, to credit quality. As such, SOP 03-3 applies to loans and debt securities acquired individually, in pools or as part of a business combination and does not apply to originated loans. The application of SOP 03-3 limits the interest income, including the accretion of purchase price discounts, that may be recognized for certain loans and debt securities. Additionally, SOP 03-3 does not allow the excess of contractual cash flows over cash flows expected to be collected to be recognized as an adjustment of yield, loss accrual or valuation allowance, such as the allowance for possible loan losses. SOP 03-3 requires that increases in expected cash flows subsequent to the initial investment be recognized prospectively through adjustment of the yield on the loan or debt security over its remaining life. Decreases in expected cash flows should be recognized as impairment. In the case of loans acquired in a business combination where the loans show signs of credit deterioration, SOP 03-3 represents a significant change from current purchase accounting practice whereby the acquiree’s allowance for loan losses is typically added to the acquirer’s allowance for loan losses. SOP 03-3 is effective for loans and debt securities acquired by the Company beginning January 1, 2005. The adoption of this new standard did not have an impact on the Company’s consolidated financial statements. (2) Acquisition On June 18, 2004, the Company acquired Local Financial Corporation (‘‘LFIN’’), an Oklahoma based bank holding company with approximately $3.0 billion in assets. The acquisition was effected pursuant to the Agreement and Plan of Merger dated as of January 22, 2004 (the ‘‘Merger Agreement’’). The Company paid consideration totaling approximately $276.6 million in cash and 2.11 million shares of Company common stock. The aggregate purchase price was $367.4 million. Under the terms of the Merger Agreement, LFIN shareholders were entitled to elect to receive either cash or Company common stock in the merger, subject to the requirement that 75% of LFIN’s shares be exchanged for cash and 25% be exchanged for Company common stock. Based on the elections of LFIN shareholders and the terms of the Merger Agreement, LFIN shares held by LFIN shareholders who elected to receive shares of Company common stock in the Merger and LFIN shareholders who did not timely make a cash/stock election were exchanged entirely for shares of Company common stock. As to those LFIN shares for which an election to receive cash was timely made, each such share was exchanged for approximately $20.59 in cash and 0.033 shares of Company common stock. The exchange rate for those LFIN shareholders receiving Company common stock in the Merger was 0.5170 shares of Company common stock for each share of LFIN. 43 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (2) Acquisition (Continued) The following table summarizes the estimated fair value of the assets acquired and liabilities assumed at the date of the acquisition, in thousands.

The contractual cash obligations of the securities are guaranteed by Freddie Mac, Fannie Mae, Ginnie Mae and the U.S. Treasury. The decrease in fair value is due to market interest rates and not other factors, and because the Company has the ability to hold these investments until a market price recovery, maturity of the securities, or a modification of the Company’s investment strategy, it is the conclusion of the Company that the investments are not considered other-than-temporarily impaired. The unrealized losses on investments in obligations of state and political subdivisions and other securities are caused by fluctuations in market interest rates. The underlying cash obligations of the securities are guaranteed by the municipality or entity underwriting the debt instrument. It is the belief of the Company that the municipality or entity issuing the debt will honor its interest payment schedule, as well as the full debt at maturity. The securities are purchased by the Company for their economic value. The decrease in fair value is primarily due to market interest rates and not other factors, and because the Company has the ability to hold these investments until a market price recovery, maturity of the securities, or a modification of the Company’s investment strategy, it is the conclusion of the Company that the investments are not considered other-than-temporarily impaired. 48 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (4) Loans A summary of net loans, by loan type at December 31, 2005 and 2004 is as follows: December 31, 2005 2004 (Dollars in thousands) Commercial, financial and agricultural . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

The effect of such non-accrual loans reduced interest income by $2,329,000, $1,203,000 and $1,870,000 for the years ended December 31, 2005, 2004 and 2003, 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. The increase in non-accrual loans from 2003 to 2004 can be attributed to certain loans the Company acquired in the LFIN acquisition. Impaired loans are those loans where it is probable that all amounts due according to contractual terms of the loan agreement will not be collected. The Company has identified these loans through its normal loan review procedures. Impaired loans are measured based on (1) the present value of expected future cash flows discounted at the loan’s effective interest rate; (2) the loan’s observable market price; or (3) the fair value of the collateral if the loan is collateral dependent. Substantially all of the Company’s 49 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (5) Allowance for Possible Loan Losses (Continued) impaired loans are measured at the fair value of the collateral. In limited cases the Company may use other methods to determine the level of impairment of a loan if such loan is not collateral dependent. The following table details key information regarding the Company’s impaired loans: 2005 2004 2003 Balance of impaired loans where there is a related allowance for loan loss . $34,796 Balance of impaired loans where there is no related allowance for loan (Dollars in Thousands) $37,037 $24,216 loss . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . — — — Total impaired loans . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $34,796 $37,037 $24,216 Allowance allocated to impaired loans . . . . . . . . . . . . . . . . . . . . . . . . . $20,014 $15,666 $ 899 The impaired loans included in the table above were primarily comprised of collateral dependent commercial loans, which have not been fully charged off. The average recorded investment in impaired loans was $29,909,000, $34,226,000, and $13,090,000 for the years ended December 31, 2005, 2004 and 2003, respectively. The increase in impaired loans in 2004 can be attributed to the LFIN acquisition. The interest recognized on impaired loans was not significant. Management of the Company recognizes the risks associated with these impaired loans. However, management’s decision to place loans in this category does not necessarily mean that losses will occur. The bank subsidiaries 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 of the Company 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 un-collectible 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 allowance for possible loan losses can be made only on a subjective basis. It is the judgment of the Company’s management that the allowance for possible loan losses at December 31, 2005 was adequate to absorb probable losses from loans in the portfolio at that date. 50 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (6) Bank Premises and Equipment A summary of bank premises and equipment, by asset classification, at December 31, 2005 and 2004 were as follows: Bank buildings and improvements . . . . . . . . . . . . . . . . . . . . . . .

As part of the LFIN acquisition, the Company acquired three additional statutory business trusts previously formed by LFIN for the purpose of issuing trust preferred securities. The eight statutory business trusts formed by the Company and the three business trusts acquired in the LFIN transaction (the ‘‘Trusts’’) have each issued Capital and Common Securities and invested the proceeds thereof in an equivalent amount of junior subordinated debentures (the ‘‘Debentures’’) issued by the Company or LFIN, as appropriate. The Company has succeeded to the obligations of LFIN under the LFIN Debentures, which have an outstanding principal balance of $62,115,000. The Debentures will mature on various dates; however the Debentures may be redeemed at specified prepayment prices, in whole or in part after the optional redemption dates specified in the respective indentures or in whole upon the occurrence of any one of certain legal, regulatory or tax events specified in respective indentures. As of December 31, 2005, the principal amount of debentures outstanding totaled $236,391,000. The Debentures are subordinated and junior in right of payment to all present and future senior indebtedness (as defined in the respective indentures) of the Company, 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. The Company has fully and unconditionally guaranteed the obligations of each of the Trusts with respect to the Capital and Common Securities. The Company has 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 ten consecutive semi-annual periods on Trusts I through IV and LFIN Trust II and for up to twenty consecutive quarterly periods on Trusts V through VIII and LFIN Trusts I and III. If interest payments on any of the Debentures are deferred, distributions on both the Capital and Common 55 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (11) Junior Subordinated Deferrable Interest Debentures (Continued) 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. In March 2005, the Federal Reserve Board issued a final rule that would continue to allow the inclusion of trust preferred securities in Tier 1 capital, but with stricter quantitative limits. Under the final rule, after a five-year transition period ending March 31, 2009, the aggregate amount of trust preferred securities and certain other capital elements would be limited to 25% of Tier 1 capital elements, net of goodwill, less any associated deferred tax liability. The amount of trust preferred securities and certain other elements in excess of the limit could be included in Tier 2 capital, subject to restrictions. Bank holding companies with significant international operations will be expected to limit trust preferred securities to 15% of Tier 1 capital elements, net of goodwill; however, they may include qualifying mandatory convertible preferred securities up to the 25% limit. Although the Capital Securities issued by each of the Trusts are not included as a component of shareholders’ equity on the consolidated statements 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. For December 31, 2005, the total $236,391,000 of the Capital Securities outstanding qualified as Tier 1 capital.

The Company’s annual contribution to the plan is based on a percentage, as determined by the 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 $4,950,000, $3,823,000 and $2,897,000 were charged to income for the years ended December 31, 2005, 2004, and 2003, respectively. 57 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (14) International Operations The Company provides international banking services for its customers through its bank subsidiaries. Neither the Company nor its bank subsidiaries have facilities located outside the United States. International operations are distinguished from domestic operations based upon the domicile of the customer. Because the resources employed by the Company are common to both international and domestic operations, it is not practical to determine net income generated exclusively from international activities.

Revenues directly attributable to international operations were $14,003,000, $11,077,000 and $11,626,000 for the years ended December 31, 2005, 2004 and 2003, respectively. 58 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (15) Income Taxes The Company files a consolidated U.S. Federal and State income tax return.

(16) Stock Options On April 1, 2005, the Board of Directors adopted the 2005 International Bancshares Corporation Stock Option Plan (the ‘‘2005 Plan’’). The 2005 Plan replaced the 1996 International Bancshares Corporation Key Contributor Stock Option Plan (the ‘‘1996 Plan’’). Under the 2005 Plan both qualified incentive stock options (‘‘ISOs’’) and nonqualified stock options (‘‘NQSOs’’) may be granted. Options granted may be exercisable for a period of up to 10 years from the date of grant, excluding ISOs granted to 10% shareholders, which may be exercisable for a period of up to only five years. Through December 31, 2005, the Company has granted nonqualified stock options exercisable for a total of 167,847 shares, adjusted for stock dividends, of Common Stock to certain employees of the GulfStar Group. The grants were not made under either the 1996 Plan or the 2005 Plan. The options are exercisable for a period of seven years and vest in equal increments over a period of five years. All options granted to the GulfStar Group employees had an option price of not less than the fair market value of the Common Stock on the date of grant. 60 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (16) Stock Options (Continued) The following schedule summarizes the pertinent information (adjusted for stock distributions) with regard to the Company’s stock options.

(17) Commitments, Contingent Liabilities and Other Tax Matters The Company is involved in various legal proceedings that are in various stages of litigation. Some of these actions allege ‘‘lender liability’’ claims on a variety of theories and claim substantial actual and punitive damages. The Company has determined, based on discussions with its 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 the consolidated financial position or results of operations of the Company. However, many of these matters are in various stages of proceedings and further developments could cause management to revise its assessment of these matters. The Company leases portions of its banking premises and equipment under operating leases. Total rental expense for the years ended December 31, 2005, 2004 and 2003 and non-cancellable lease commitments at December 31, 2005 were not significant. Cash of approximately $50,625,000 and $50,411,000 at December 31, 2005 and 2004, respectively, was maintained to satisfy regulatory reserve requirements. The Company’s lead bank subsidiary has invested in partnerships, which have entered into several lease-financing transactions. The lease-financing transactions in two of the partnerships have been examined by the Internal Revenue Service (‘‘IRS’’). In both partnerships, the lead bank subsidiary is the owner of a ninety-nine percent (99%) limited partnership interest. The IRS has issued separate Notice of Final Partnership Administrative Adjustments (‘‘FPAA’’) to the partnerships and on September 25, 2001, and January 10, 2003, the Company filed lawsuits contesting the adjustments asserted in the FPAAs. Prior to filing the respective lawsuits, the Company was required to deposit the estimated tax due of approximately $4,083,000 with respect to the first FPAA, and $7,710,606 with respect to the second FPAA, with the IRS pursuant to the Internal Revenue Code. If it is determined that the amount of tax due, if any, related to the lease-financing transactions is less than the amount of the deposits, the remaining amount of the deposits would be returned to the Company. The case with respect to the first FPAA was tried during August 2005. Post-trial briefs were filed in January and February 2006. In order to curtail the accrual of additional interest related to the disputed tax benefits and because interest rates were unfavorable, on March 7, 2003, the Company submitted to the IRS a total of $13,640,797, which constitutes the interest that would have accrued based on the adjustments proposed in the FPAAs related to both of the lease-financing transactions. If it is determined that the amount of 62 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (17) Commitments, Contingent Liabilities and Other Tax Matters (Continued) interest due, if any, related to the lease-financing transactions is less than the $13,640,797, the remaining amount of the prepaid interest will be refunded to the Company, plus interest thereon. No reliable prediction can be made at this time as to the likely outcome of the lawsuits; however, if the lawsuits are decided adversely to the partnerships, all or a portion of the $12 million in tax benefits previously recognized by the Company in connection with the Partnerships’ lease-financing transactions would be in question and penalties and interest could be assessed by the IRS. The Company has accrued approximately $12 million at December 31, 2005 in connection with the lawsuits. Management intends to continue to evaluate the merits of each matter and make appropriate revisions to the accrued amount as deemed necessary. As part of the LFIN acquisition, the Company acquired two tax matters. The first relates to deductions taken on amended returns filed by LFIN during 2003 for the tax years ended June 30, 1999 through December 31, 2001. The refunds requested on the amended returns amounted to approximately $7,000,000. At December 31, 2003, LFIN had received approximately $2,000,000 of the total refund requested. Because all the refunds are under review by the IRS, LFIN had established a reserve equal to the $2,000,000 received and did not recognize any benefit for the remaining $5,000,000. The second tax contingency, which is also approximately $7,000,000, relates to permanent differences applicable to prior periods taken as deductions in 2002 and was received by LFIN during 2003. LFIN had recorded a reserve equal to the amounts received pending final resolution with the IRS. Both reserves are included in the current income taxes payable of the Company. The Company will continue to monitor the IRS reviews. (18) Transactions with Related Parties In the ordinary course of business, the subsidiaries of the Company make loans to directors and executive officers of the Corporation, 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 collectibility or present other unfavorable features. The aggregate amounts receivable from such related parties amounted to approximately $41,261,000 and $43,430,000 at December 31, 2005 and 2004, respectively. (19) Financial Instruments with Off-Statement of Condition Risk and Concentrations of Credit Risk In the normal course of business, the bank subsidiaries 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 bank subsidiaries have in particular classes of financial instruments. At December 31, 2005, the following financial amounts of instruments, whose contract amounts represent credit risks, were outstanding: Commitments to extend credit . . . . . . . . . . . . . . . . . . . . . . . . . . . .

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, the Company is 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, 2005, the maximum potential amount of future payments is $122,384,000. At December 31, 2005, the fair value of these guarantees is not significant. The Company enters into commercial letters of credit on behalf of its customers which authorize a third party to draw drafts on the Company up to a stipulated amount and with specific terms and conditions. A commercial letter of credit is a conditional commitment on the part of the Company to provide payment on drafts drawn in accordance with the terms of the commercial letter of credit. The bank subsidiaries’ 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 bank subsidiaries use the same credit policies in making commitments and conditional obligations as they do for on-statement of condition instruments. The bank subsidiaries 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 bank subsidiaries 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 bank subsidiaries 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. 64 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (20) Dividend Restrictions and Capital Requirements Bank regulatory agencies limit the amount of dividends, which the bank subsidiaries can pay the Corporation, through IBC Subsidiary Corporation, without obtaining prior approval from such agencies. At December 31, 2005, the subsidiary banks could pay dividends of up to $169,500,000 to the Company without prior regulatory approval and without adversely affecting their ‘‘well capitalized’’ status. In addition to legal requirements, regulatory authorities also consider the adequacy of the bank subsidiaries’ total capital in relation to their deposits and other factors. These capital adequacy considerations also limit amounts available for payment of dividends. The Company historically has not allowed any subsidiary bank to pay dividends in such a manner as to impair its capital adequacy. The Company and the bank subsidiaries 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 the Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company must meet specific capital guidelines that involve quantitative measures of the Company’s assets, liabilities, and certain off-statement of condition items as calculated under regulatory accounting practices. The Company’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company 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, 2005, that the Company and each of the bank subsidiaries met all capital adequacy requirements to which it is subject. As of December 31, 2005, the most recent notification from the Federal Deposit Insurance Corporation categorized all the bank subsidiaries as well capitalized under the regulatory framework for prompt corrective action. To be categorized as ‘‘well capitalized’’ the Company and the bank subsidiaries must maintain minimum Total risk-based, Tier 1 risk based, and Tier 1 leverage ratios as set forth in the table.

Cash and Due From Banks and Federal Funds Sold For these short-term instruments, the carrying amount is a reasonable estimate of fair value. Time Deposits with Banks As the contract interest rates are comparable to current market rates, the carrying amount approximates fair market value. Investment Securities For investment securities, which include U. S. Treasury securities, obligations of other U. S. government agencies, obligations of states and political subdivisions and mortgage pass through and related securities, fair values are based on quoted market prices or dealer quotes. Fair values are based on the value of one unit without regard to any premium or discount that may result from concentrations of ownership of a financial instrument, possible tax ramifications, or estimated transaction costs. See disclosures of fair value of investment securities in Note 3. Loans Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial, real estate and consumer loans as outlined by regulatory reporting guidelines. Each category is segmented into fixed and variable interest rate terms and by performing and non-performing categories. For variable rate performing loans, the carrying amount approximates the fair value. For fixed rate performing loans, except residential mortgage loans, the fair value is calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest rate risk inherent in the loan. For performing residential mortgage loans, fair value is estimated by discounting contractual cash flows adjusted for prepayment estimates using discount rates based on secondary market sources or the primary origination market. At December 31, 2005 and 2004, the carrying amount of fixed rate performing loans was $1,398,838,000 and $1,681,916,000 respectively, and the estimated fair value was $1,382,409,000 and $1,679,719,000, respectively. Fair value for significant non-performing loans is based on recent external appraisals. If appraisals are not available, estimated cash flows are discounted using a rate commensurate with the risk associated with the estimated cash flows. Assumptions regarding credit risk, cash flows and discount rates are judgmentally determined using available market and specific borrower information. As of December 31, 2005 and 2004, the net carrying amount of non-performing loans was a reasonable estimate of the 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, 2005 and 2004. 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. At December 31, 68 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (21) Fair Value of Financial Instruments (Continued) 2005 and 2004, the carrying amount of time deposits was $3,160,812,000 and $3,188,003,000, respectively, and the estimated fair value was $3,175,624,000 and $3,197,198,000, respectively. Securities Sold Under Repurchase Agreements and Other Borrowed Funds Due to the contractual terms of these financial instruments, the carrying amounts approximated fair value at December 31, 2005 and 2004. Junior Subordinated Deferrable Interest Debentures Due to the contractual terms of these financial instruments, the carrying amounts approximated fair value at December 31, 2005. 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 the Company’s entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing on-and off-statement of condition financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Other significant assets and liabilities that are not considered financial assets or liabilities include the bank premises and equipment and core deposit value. In addition, the tax ramifications related to the effect of fair value estimates have not been considered in the above estimates. 69 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (22) International Bancshares Corporation (Parent Company Only) Financial Information Statements of Condition (Parent Company Only) December 31, 2005 and 2004 (Dollars in Thousands) ASSETS Cash . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
