INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES

Notes to Consolidated Financial Statements

(Unaudited)

Note 1 - Basis of Presentation

The accounting and reporting policies of International Bancshares Corporation (“Corporation”) and Subsidiaries (the Corporation and Subsidiaries collectively referred to herein as the “Company”) conform to accounting principles generally accepted in the United States of America and to general practices within the banking industry.  The consolidated financial statements include the accounts of the Corporation and its wholly-owned 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, as well as the GulfStar Group in which the Company owns a controlling interest.  All significant inter-company balances and transactions have been eliminated in consolidation.  The consolidated financial statements are unaudited, but include all adjustments, which, in the opinion of management, are necessary for a fair presentation of the results of the periods presented.  All such adjustments were of a normal and recurring nature.  It is suggested that these financial statements be read in conjunction with the financial statements and the notes thereto in the Company’s latest Annual Report on Form 10K.  The consolidated statement of condition at December 31, 2004 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements.  Certain reclassifications have been made to make prior periods comparable.

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 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 operating segments meets the 10% threshold for disclosure under SFAS No. 131.

All per share data presented has been restated to reflect the stock splits effected through stock dividends, see Note 8.

Note 3 – 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 of Financial Accounting Standards No. 123 (“SFAS No. 123”), “Accounting for Stock-Based 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 of income based on their fair values on the date of the grant.  The Company will be required to adopt the provisions of SFAS No. 123R on January 1, 2006.

At June 30, 2005, the Company had one stock-based employee compensation plan under which options are outstanding and certain options granted outside the plan.  An additional stock-based employee compensation plan has been adopted by the Company, but no options have been granted under such 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.

Note 4 - Investment Securities

The Company classifies debt and equity securities into one of three 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 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 (loss) income and accumulated other comprehensive (loss) income until realized.

Note 5 - Allowance for Possible Loan Losses

A summary of the transactions in the allowance for possible loan losses is as follows:

	June 30,			June 30,
	2005			2004
	(Dollars in Thousands)
Balance at December 31,	$	81,351		$	48,646

Balance at June 30,	$	82,114		$	84,571

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 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.

10

The following table details key information regarding the Company’s impaired loans:

	June 30,		December 31,
	2005		2004
	(Dollars in Thousands)
Balance of impaired loans where there is a related allowance for loan loss	$	26,218	$	37,037
Balance of impaired loans where there is no related allowance for loan loss	—		—
Total impaired loans	$	26,218	$	37,037
Allowance allocated to impaired loans	$	16,265	$	15,666

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 $39,008,000 and $34,226,000 for June 30, 2005 and December 31, 2004, respectively.  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 June 30, 2005 was adequate to absorb probable losses from loans in the portfolio at that date.

Note 6 – Other Borrowed Funds

Other borrowed funds include Federal Home Loan Bank borrowings, which are short or long term, variable or fixed borrowings issued by the Federal Home Loan Bank of Dallas at the market price offered at the time of funding.  These borrowings are secured by mortgage-backed investment securities and a portion of the Company’s loan portfolio.  At June 30, 2005, other borrowed funds totaled $1,885,193,000 an increase of 12.9% from $1,670,199,000 at December 31, 2004.  The increase in other borrowed funds can be attributed to the additional funding needs of the Company.

Note 7 – Junior Subordinated Interest Deferrable 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.  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 June 30, 2005, the principal amount of debentures outstanding totaled $235,908,000.

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.  The Company believes that substantially all of the $235,908,000 will be included in Tier 1 capital after the five-year transition period ending March 31, 2009.

The following table illustrates key information about each of the Capital and Common Securities and their interest rate at June 30, 2005:

Note 8 – Common Stock and Dividends

All per share data presented has been restated to reflect the stock splits effected through stock dividends, which became effective May 2, 2005 and May 3, 2004 and were paid on May 31, 2005 and May 28, 2004, respectively.  Cash dividends of $.32 per share, adjusted for stock dividends, were paid on April 29, 2005 to all holders of record on April 15, 2005.

The Company expanded its formal stock repurchase program on December 16, 2004.  Under the expanded stock repurchase program, the Company is authorized to repurchase up to $175,000,000 of its common stock through December 2005.  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 August 1, 2005, a total of 3,934,393 shares had been repurchased under this program at a cost of $153,020,000.  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 August 1, 2005, the Company has approximately $173,994,000 invested in treasury shares, which amount has been accumulated since the inception of the Company.

On May 16, 2005, the Corporation’s shareholders adopted the 2005 International Bancshares Corporation Stock Option Plan (the “2005 Plan”).  The 2005 Plan became effective on April 1, 2005, the date it was approved and adopted by the Corporation’s Board of Directors, upon such shareholder approval.  The Plan replaces the 1996 International Bancshares Corporation Stock Option Plan (the “1996 Plan”), which will be terminated for purposes of granting further options.  The 2005 Plan provides for the grant of incentive stock options and non-statutory stock options.  The Stock Option Plan committee of the Board of Directors administers the 2005 Plan and determines the terms and conditions under with options to purchase shares of common stock of the Corporation may be awarded.  The aggregate number of shares of common stock of the Corporation that may be issued pursuant to the 2005 Plan is 380,000 shares, subject to adjustment as provided in the 2005 Plan.  Further, the maximum number of shares of common stock covered by options which may be granted to any one person in any fiscal year is 75,000, also subject to adjustment as provided in the 2005 Plan.  Neither the 380,000 aggregate shares limitation nor the 75,000 individual annual limitation described above reflects the appropriate adjustment for the May 2, 2005 stock dividend.

Note 9 - Commitments and Contingent Liabilities

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 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’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 was 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 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.

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 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

13

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 June 30, 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.

Note 10 – Capital Ratios

The Company had a leverage ratio of 6.80% and 6.91%, risk-weighted Tier 1 capital ratio of 11.69% and 10.74% and risk-weighted total capital ratio of 12.94% and 11.99% at June 30, 2005 and December 31, 2004, respectively.  The net identified intangibles and goodwill of $331,065,000 as of June 30, 2005, recorded in connection with the acquisitions made by the Company, are deducted from the sum of core capital elements when determining the capital ratios of the Company.  The Company actively monitors the regulatory capital ratios to ensure that the Company’s bank subsidiaries are well capitalized under the regulatory framework.

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.

Overview

The Company, which is headquartered in Laredo, Texas, with more than 180 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 the 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.

The Company is very active in facilitating trade along the United States border with Mexico.  The Company does a significant amount of business with customers domiciled in Mexico.  Deposits from persons and entities domiciled in Mexico comprise a significant 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 54% for each of the last five years, which the Company believes is better than average compared to its national peer group.  One of the benefits derived from such operating efficiencies is that the Company is not subject to undue pressure to generate interest income from high-risk loans.

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.  Net interest income was positively impacted by the acquisition of LFIN, as well as increasing portfolio levels and increasing market rates on interest bearing asset and interest bearing liabilities.

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 (see table on page 21 for the June 30, 2005 gap analysis).  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.

The increase in non-banking service charges, commissions and fees can be attributed to the acquisition of LFIN.  The Company recorded investment securities losses of $181,000 for the six months ended June 30, 2005 compared to gains of $8,461,000 for the same period of 2004.  The increase in other income 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, of which $7,363,000 was received in the first quarter 2005 and $1,273,000 was received in the second quarter.  Members of the PULSE EFT Association received these distributions based in part upon their volume of transactions through the PULSE network.

Total non-interest expense	$	64,989	$	40,889	58.9	%	$	125,013		$		78,576	59.1	%

The increase in employee compensation and benefits expense for the quarter and six months ended June 30, 2005 compared to the quarter and six months ended June 30, 2004 can be attributed primarily to the expanded operations of the Company’s bank subsidiaries (including the acquisition of LFIN in June 2004, which added approximately 700 employees, 52 branches and $42,188,000 in identified intangible assets).

The allowance for possible loan losses increased .9% to $82,114,000 at June 30, 2005 from $81,351,000 at December 31, 2004.  The provision for possible loan losses charged to expense increased 4.2% to $2,831,000 for the six months ended June 30, 2005 from $2,717,000 for the same period in 2004.  The increase in the provision for possible loan losses charged to expense can be attributed primarily to the substantial increase in the loan portfolio as part of the LFIN acquisition.  The allowance for possible loan losses was 1.7% of total loans, net of unearned income, at June 30, 2005 and at December 31, 2004.

Investment Securities

Investment securities increased 5.3% to $4,082,451,000 at June 30, 2005, from $3,877,218,000 at December 31, 2004.

Foreign Operations

On June 30, 2005, the Company had $10,273,970,000 of consolidated assets, of which approximately $259,841,000, or 2.5%, was related to loans outstanding to borrowers domiciled in Mexico, compared to $239,622,000, or 2.4%, at December 31, 2004.  Of the $259,841,000, 77.0% is directly or indirectly secured by U.S. assets, certificates of deposits and real estate; 17.7% is secured by Mexican real estate; .4% is secured by Mexican real estate related to maquiladora plants and guaranteed under lease obligations primarily by U.S. companies, many of which are on the Fortune 500 list of companies; 4.3% is unsecured; and .6% represents accrued interest receivable on the portfolio.

Critical Accounting Policies

The Company has established various accounting policies which govern the application of accounting principles in the preparation of the Company’s 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.  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 the results of operations and “Provision and Allowance for Possible Loan Losses” included in Notes 1 and 5 of the notes to Consolidated Financial Statements in the Company’s latest Annual Report on Form 10K for further information regarding the Company’s provision and allowance for possible loan losses policy.

Liquidity and Capital Resources

The maintenance of adequate liquidity provides the Company’s bank subsidiaries with the ability to meet potential depositor withdrawals, provide for customer credit needs, maintain adequate statutory reserve levels and take full advantage of high-yield investment opportunities as they arise.  Liquidity is afforded by access to financial markets and by holding appropriate amounts of liquid assets.  The Company’s bank subsidiaries derive their liquidity largely from deposits of individuals and business entities.  Deposits from persons and entities domiciled in Mexico comprise a significant and stable portion of the deposit base of the Company’s bank subsidiaries. Other important funding sources for the Company’s bank subsidiaries during 2005 and 2004 have been borrowings from 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 loans.  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.

The Company maintains an adequate level of capital as a margin of safety for its depositors and shareholders.  At June 30, 2005, shareholders’ equity was $780,139,000 compared to $753,090,000 at December 31, 2004, an increase of $27,049,000, or 3.6%.  The change in shareholders’ equity can be attributed to the retention of earnings offset by a decrease in the unrealized gain on available for sale investments.

The Company had a leverage ratio of 6.80% and 6.91%, risk-weighted Tier 1 capital ratio of 11.69% and 10.74% and risk-weighted total capital ratio of 12.94% and 11.99% at June 30, 2005 and December 31, 2004, respectively.  The identified intangibles and goodwill of $331,065,000 as of June 30, 2005, recorded in connection with the Company’s acquisitions, are deducted from the sum of core capital elements when determining the capital ratios of the Company.

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 anticipate fluctuations in interest rates by adjusting the balance between sources and uses of funds as deemed appropriate.  The net-interest rate sensitivity as of June 30, 2005 is illustrated in the table on the following page.  This information reflects the balances of assets and liabilities for which rates are subject to change.  A mix of assets and liabilities that are roughly equal in volume and re-pricing characteristics represents a matched interest rate sensitivity position.  Any excess of assets or liabilities results in an interest rate sensitivity gap.

The Company undertakes an interest rate sensitivity analysis to monitor the potential risk on future earnings resulting from the impact of possible future changes in interest rates on currently existing net asset or net liability positions.  However, this type of analysis is as of a point-in-time position, when in fact that position can quickly change as market conditions, customer needs, and management strategies change. Thus, interest rate changes do not affect all categories of asset and liabilities equally or at the same time.  As indicated in the table, the Company is liability sensitive during the early time periods and asset sensitive in the longer periods.  The Company’s Asset and Liability Committee semi-annually reviews the consolidated position along with simulation and duration models, and makes adjustments as needed to control the Company’s interest rate risk position.  The Company uses modeling of future events as a primary tool for monitoring interest rate risk.

Item 4.  Controls and Procedures

Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures designed to ensure that information required to be disclosed in reports filed under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within specified time periods.  As of the end of the period covered by this Quarterly Report on Form 10-Q, the Company’s chief Executive Officer and Chief Financial Officer evaluated, with the participation of the Company’s management, the effectiveness of the Company’s disclosure controls and procedures (as defined in Exchange Act rules 13a-15(e) and 15d-15(e)).  Based on the evaluation, which disclosed no significant deficiencies or material weaknesses, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of the end of the period covered by this report.

Internal Control Over Financial Reporting

There were no significant changes in the Company’s internal control over financial reporting that occurred during the Company’s most recent fiscal quarter that have materially affected or are reasonably likely to materially affect the Company’s internal control over financial reporting.

PART II - OTHER INFORMATION

Item 1.  Legal Proceedings

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’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 lawsuit 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.

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 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 June 30, 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.

Item 2.  Unregistered Sales of Equity Securities and Use of Proceeds

The Company expanded its formal stock repurchase program on December 16, 2004. Under the expanded stock repurchase program, the Company is authorized to repurchase up to $175,000,000 of its common stock through December 2005.  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 August 1, 2005, a total of 3,934,393 shares had been repurchased under this program at a cost of $153,020,000, which shares are now reflected as 10,805,090 shares of treasury stock as adjusted for stock dividends.  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 August 1, 2005, the Company has approximately $173,994,000 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.  The following table includes information about share repurchases for the quarter ended June 30, 2005.

	Total Number of Shares Purchased	Average Price Paid Per Share (2)		Shares Purchased as Part of a Publicly- Announced Program	Approximate Dollar Value of Shares Available for Repurchase (1) (2)
April 1 – April 30, 2005	6,556	27.76		—	$	29,051,000
May 1 – May 31, 2005	261,458	28.45		250,000	22,002,000
June 1 – June 30, 2005	595	28.00		—	21,985,000
	268,609	$	28.43	250,000

(1)The formal stock repurchase program was initiated in 1999 and has been expanded periodically.  The current program allows for the repurchase of up to $175,000,000 of treasury stock through December 2005 of which $21,985,000 remains.

(2)The average price paid per share reflects the Company stock dividend paid on May 31, 2005.
