Notes to Consolidated Financial Statements

(Table amounts are stated in thousands, except for share and per share amounts)

Note 1 - Significant Accounting Policies

Nature of Operations. Cullen/Frost Bankers, Inc. (Cullen/Frost) is a financial holding company and a bank holding company headquartered in San Antonio, Texas that provides, through its subsidiaries, a broad array of products and services throughout numerous Texas markets. In addition to general commercial and consumer banking, other products and services offered include trust and investment management, investment banking, insurance, brokerage, leasing, asset-based lending, treasury management and item processing.

Basis of Presentation. The consolidated financial statements in this Quarterly Report on Form 10-Q include the accounts of Cullen/Frost and all other entities in which Cullen/Frost has a controlling financial interest (collectively referred to as the “Corporation”). All significant intercompany balances and transactions have been eliminated in consolidation. The accounting and financial reporting policies the Corporation follows conform, in all material respects, to accounting principles generally accepted in the United States and to general practices within the financial services industry.

The consolidated financial statements in this Quarterly Report on Form 10-Q have not been audited by an independent registered public accounting firm, but in the opinion of management, reflect all adjustments necessary for a fair presentation of the Corporation’s financial position and results of operations. All such adjustments were of a normal and recurring nature. The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q adopted by the Securities and Exchange Commission (SEC). Accordingly, the financial statements do not include all of the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements and should be read in conjunction with the Corporation’s consolidated financial statements, and notes thereto, for the year ended December 31, 2010, included in the Corporation’s Annual Report on Form 10-K filed with the SEC on February 3, 2011 (the “2010 Form 10-K”). Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period.

Use of Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The allowance for loan losses, the fair value of stock-based compensation awards, the fair values of financial instruments and the status of contingencies are particularly subject to change.

Cash Flow Reporting. Additional cash flow information was as follows:


	Six Months Ended June 30,
	2011		2010
Cash paid for interest	$	24,473	$	30,027
Cash paid for income tax		12,406		27,979

Common stock/treasury stock issued to the Corporation’s 401(k) stock purchase plan		1,360		5,318

Reclassifications. Certain items in prior financial statements have been reclassified to conform to the current presentation.

A summary of the amortized cost and estimated fair value of securities, excluding trading securities, is presented below.

All mortgage-backed securities included in the above table were issued by U.S. government agencies and corporations. Securities with limited marketability, such as stock in the Federal Reserve Bank and the Federal Home Loan Bank, are carried at cost and are reported as other available for sale securities in the above table. The carrying value of securities pledged to secure public funds, trust deposits, repurchase agreements and for other purposes, as required or permitted by law was $2.1 billion and $2.3 billion at June 30, 2011 and December 31, 2010.

As of June 30, 2011, securities, with unrealized losses segregated by length of impairment, were as follows:


	Less than 12 Months				More than 12 Months				Total
	Estimated Fair Value		Unrealized Losses		Estimated Fair Value		Unrealized Losses		Estimated Fair Value		Unrealized Losses
Held to Maturity
States and political subdivisions	$	23,446	$	345	$	—	$	—	$	23,446	$	345

Total	$	23,446	$	345	$	—	$	—	$	23,446	$	345

Available for Sale
Residential mortgage-backed securities	$	352	$	2	$	—	$	—	$	352	$	2
States and political subdivisions		271,806		2,527		667		27		272,473		2,554

Total	$	272,158	$	2,529	$	667	$	27	$	272,825	$	2,556

Declines in the fair value of held-to-maturity and available-for-sale securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses to the extent the impairment is related to credit losses. The amount of the impairment related to other factors is recognized in other comprehensive income. In estimating other-than-temporary impairment losses, management considers, among other things, (i) the length of time and the extent to which the fair value has been less than cost, (ii) the financial condition and near-term prospects of the issuer, and (iii) the intent and ability of the Corporation to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in cost.

Management has the ability and intent to hold the securities classified as held to maturity in the table above until they mature, at which time the Corporation will receive full value for the securities. Furthermore, as of June 30, 2011, management does not have the intent to sell any of the securities classified as available for sale in the table above and believes that it is more likely than not that the Corporation will not have to sell any such securities before a recovery of cost. Any unrealized losses are largely due to increases in market interest rates over the yields available at the time the underlying securities were purchased. The fair value is expected to recover as the bonds approach their maturity date or repricing date or if market yields for such investments decline. Management does not believe any of the securities are impaired due to reasons of credit quality. Accordingly, as of June 30, 2011, management believes the impairments detailed in the table above are temporary and no impairment loss has been realized in the Corporation’s consolidated income statement.

The amortized cost and estimated fair value of securities, excluding trading securities, at June 30, 2011 are presented below by contractual maturity. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations. Residential mortgage-backed securities and equity securities are shown separately since they are not due at a single maturity date.

Loan Origination/Risk Management. The Corporation has certain lending policies and procedures in place that are designed to maximize loan income within an acceptable level of risk. Management reviews and approves these policies and procedures on a regular basis. A reporting system supplements the review process by providing management with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies and non-performing and potential problem loans. Diversification in the loan portfolio is a means of managing risk associated with fluctuations in economic conditions.

Commercial and industrial loans are underwritten after evaluating and understanding the borrower’s ability to operate profitably and prudently expand its business. Underwriting standards are designed to promote relationship banking rather than transactional banking. Once it is determined that the borrower’s management possesses sound ethics and solid business acumen, the Corporation’s management examines current and projected cash flows to determine the ability of the borrower to repay their obligations as agreed. Commercial and industrial loans are primarily made based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not be as expected and the collateral securing these loans may fluctuate in value. Most commercial and industrial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee; however, some short-term loans may be made on an unsecured basis. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers.

Commercial real estate loans are subject to underwriting standards and processes similar to commercial and industrial loans, in addition to those of real estate loans. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts and the repayment of these loans is generally largely dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. Commercial real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. The properties securing the Corporation’s commercial real estate portfolio are diverse in terms of type and geographic location. This diversity helps reduce the Corporation’s exposure to adverse economic events that affect any single market or industry. Management monitors and evaluates commercial real estate loans based on collateral, geography and risk grade criteria. As a general rule, the Corporation avoids financing single-purpose

projects unless other underwriting factors are present to help mitigate risk. The Corporation also utilizes third-party experts to provide insight and guidance about economic conditions and trends affecting market areas it serves. In addition, management tracks the level of owner-occupied commercial real estate loans versus non-owner occupied loans. At June 30, 2011, approximately 61% of the outstanding principal balance of the Corporation’s commercial real estate loans were secured by owner-occupied properties.

With respect to loans to developers and builders that are secured by non-owner occupied properties that the Corporation may originate from time to time, the Corporation generally requires the borrower to have had an existing relationship with the Corporation and have a proven record of success. Construction loans are underwritten utilizing feasibility studies, independent appraisal reviews, sensitivity analysis of absorption and lease rates and financial analysis of the developers and property owners. Construction loans are generally based upon estimates of costs and value associated with the complete project. These estimates may be inaccurate. Construction loans often involve the disbursement of substantial funds with repayment substantially dependent on the success of the ultimate project. Sources of repayment for these types of loans may be pre-committed permanent loans from approved long-term lenders, sales of developed property or an interim loan commitment from the Corporation until permanent financing is obtained. These loans are closely monitored by on-site inspections and are considered to have higher risks than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, governmental regulation of real property, general economic conditions and the availability of long-term financing.

The Corporation originates consumer loans utilizing a computer-based credit scoring analysis to supplement the underwriting process. To monitor and manage consumer loan risk, policies and procedures are developed and modified, as needed, jointly by line and staff personnel. This activity, coupled with relatively small loan amounts that are spread across many individual borrowers, minimizes risk. Additionally, trend and outlook reports are reviewed by management on a regular basis. Underwriting standards for home equity loans are heavily influenced by statutory requirements, which include, but are not limited to, a maximum loan-to-value percentage of 80%, collection remedies, the number of such loans a borrower can have at one time and documentation requirements.

The Corporation maintains an independent loan review department that reviews and validates the credit risk program on a periodic basis. Results of these reviews are presented to management. The loan review process complements and reinforces the risk identification and assessment decisions made by lenders and credit personnel, as well as the Corporation’s policies and procedures.

Concentrations of Credit. Most of the Corporation’s lending activity occurs within the State of Texas, including the four largest metropolitan areas of Austin, Dallas/Ft. Worth, Houston and San Antonio, as well as other markets. The majority of the Corporation’s loan portfolio consists of commercial and industrial and commercial real estate loans. As of June 30, 2011, there were no concentrations of loans related to any single industry in excess of 10% of total loans.

Student Loans Held for Sale. Prior to the second quarter of 2008, the Corporation originated student loans primarily for sale in the secondary market. These loans were generally sold on a non-recourse basis and were carried at the lower of cost or market on an aggregate basis. During the second quarter of 2008, the Corporation elected to discontinue the origination of student loans for resale, aside from previously outstanding commitments. All remaining student loans were sold during the second quarter of 2010.

Foreign Loans. The Corporation has U.S. dollar denominated loans and commitments to borrowers in Mexico. The outstanding balance of these loans and the unfunded amounts available under these commitments were not significant at June 30, 2011 or December 31, 2010.

Non-Accrual and Past Due Loans. Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Loans are placed on non-accrual status when, in management’s opinion, the borrower may be unable to meet payment obligations as they become due, as well as when required by regulatory provisions. In determining whether or not a borrower may be unable to meet payment obligations for each class of loans, the Corporation considers the borrower’s debt service capacity through the analysis of current financial information, if available, and/or current information with regards to the Corporation’s collateral position. Regulatory provisions would typically require the placement of a loan on non-accrual status if (i) principal or interest has been in default for a period of 90 days or more unless the loan is both well secured and in the process of collection, or (ii) full payment of principal and interest is not expected. Loans may be placed on non-accrual status regardless of whether or not such loans are considered past due. When interest accrual is discontinued, all unpaid accrued interest is reversed. Interest income on non-accrual loans is recognized only to the extent that cash payments are received in excess of principal due. A loan may be returned to accrual status when all the principal and interest amounts contractually due are brought current and future principal and interest amounts contractually due are reasonably assured, which is typically evidenced by a sustained period (at least six months) of repayment performance by the borrower.

Non-accrual loans, segregated by class of loans, were as follows:

Had non-accrual loans performed in accordance with their original contract terms, the Corporation would have recognized additional interest income, net of tax, of approximately $861 thousand and $1.7 million for the three and six months ended June 30, 2011, compared to $964 thousand and $2.0 million for the same periods in 2010.

Impaired Loans. Loans are considered impaired when, based on current information and events, it is probable the Corporation will be unable to collect all amounts due in accordance with the original contractual terms of the loan agreement, including scheduled principal and interest payments. Impairment is evaluated in total for smaller-balance loans of a similar nature and on an individual loan basis for other loans. If a loan is impaired, a specific valuation allowance is allocated, if necessary, so that the loan is reported net, at the present value of estimated future cash flows using the loan’s existing rate or at the fair value of collateral if repayment is expected solely from the collateral. Interest payments on impaired loans are typically applied to principal unless collectability of the principal amount is reasonably assured, in which case interest is recognized on a cash basis. Impaired loans, or portions thereof, are charged off when deemed uncollectible.

Regulatory guidelines require the Corporation to reevaluate the fair value of collateral supporting impaired collateral dependent loans on at least an annual basis. While the Corporation’s policy is to comply with the regulatory guidelines, the Corporation’s general practice is to reevaluate the fair value of collateral supporting impaired collateral dependent loans on a quarterly basis. Thus, appraisals are never considered to be outdated, and the Corporation does not need to make any adjustments to the appraised values. The fair value of collateral supporting impaired collateral dependent loans is evaluated by the Corporation’s internal appraisal services using a methodology that is consistent with the Uniform Standards of Professional Appraisal Practice. The fair value of collateral supporting impaired collateral dependent construction loans is based on an “as is” valuation.

Impaired loans are set forth in the following table. No interest income was recognized on impaired loans subsequent to their classification as impaired.

Credit Quality Indicators. As part of the on-going monitoring of the credit quality of the Corporation’s loan portfolio, management tracks certain credit quality indicators including trends related to (i) the weighted-average risk grade of commercial loans, (ii) the level of classified commercial loans, (iii) the delinquency status of consumer loans (see details above) (iv) net charge-offs, (v) non-performing loans (see details above) and (vi) the general economic conditions in the State of Texas.

The Corporation utilizes a risk grading matrix to assign a risk grade to each of its commercial loans. Loans are graded on a scale of 1 to 14. A description of the general characteristics of the 14 risk grades is as follows:

•

Grades 1, 2 and 3 - These grades include loans to very high credit quality borrowers of investment or near investment grade. These borrowers are generally publicly traded (grades 1 and 2), have significant capital strength, moderate leverage, stable earnings and growth, and readily available financing alternatives. Smaller entities, regardless of strength, would generally not fit in these grades.

•

Grades 4 and 5 - These grades include loans to borrowers of solid credit quality with moderate risk. Borrowers in these grades are differentiated from higher grades on the basis of size (capital and/or revenue), leverage, asset quality and the stability of the industry or market area.

•

Grades 6, 7 and 8 - These grades include “pass grade” loans to borrowers of acceptable credit quality and risk. Such borrowers are differentiated from Grades 4 and 5 in terms of size, secondary sources of repayment or they are of lesser stature in other key credit metrics in that they may be over-leveraged, under capitalized, inconsistent in performance or in an industry or an economic area that is known to have a higher level of risk, volatility, or susceptibility to weaknesses in the economy.

•

Grade 9 - This grade includes loans on management’s “watch list” and is intended to be utilized on a temporary basis for pass grade borrowers where a significant risk-modifying action is anticipated in the near term.

•

Grade 10 - This grade is for “Other Assets Especially Mentioned” in accordance with regulatory guidelines. This grade is intended to be temporary and includes loans to borrowers whose credit quality has clearly deteriorated and are at risk of further decline unless active measures are taken to correct the situation.

•

Grade 11 - This grade includes “Substandard” loans, in accordance with regulatory guidelines, for which the accrual of interest has not been stopped. By definition under regulatory guidelines, a “Substandard” loan has defined weaknesses which make payment default or principal exposure likely, but not yet certain. Such loans are apt to be dependent upon collateral liquidation, a secondary source of repayment or an event outside of the normal course of business.

•

Grade 12 - This grade includes “Substandard” loans, in accordance with regulatory guidelines, for which the accrual of interest has been stopped. This grade includes loans where interest is more than 120 days past due and not fully secured and loans where a specific valuation allowance may be necessary, but generally does not exceed 30% of the principal balance.

•

Grade 13 - This grade includes “Doubtful” loans in accordance with regulatory guidelines. Such loans are placed on non-accrual status and may be dependent upon collateral having a value that is difficult to determine or upon some near-term event which lacks certainty. Additionally, these loans generally have a specific valuation allowance in excess of 30% of the principal balance.

•

Grade 14 - This grade includes “Loss” loans in accordance with regulatory guidelines. Such loans are to be charged-off or charged-down when payment is acknowledged to be uncertain or when the timing or value of payments cannot be determined. “Loss” is not intended to imply that the loan or some portion of it will never be paid, nor does it in any way imply that there has been a forgiveness of debt.

In monitoring credit quality trends in the context of assessing the appropriate level of the allowance for loan losses, the Corporation monitors portfolio credit quality by the weighted-average risk grade of each class of commercial loan. Individual relationship managers review updated financial information for all pass grade loans to recalculate the risk grade on at least an annual basis. When a loan has a calculated risk grade of 9, it is still considered a pass grade loan; however, it is considered to be on management’s “watch list,” where a significant risk-modifying action is anticipated in the near term. When a loan has a calculated risk grade of 10 or higher, a special assets officer monitors the loan on an on-going basis. The following table presents weighted average risk grades for all loans by class of commercial loan.

The Corporation does not subsequently monitor loan-to-value ratios (either individually or on a weighted-average basis) for loans that are subsequently considered to be of a pass grade (grades 9 or better) and/or current with respect to principal and interest payments. As stated above, when an individual commercial real estate loan has a calculated risk grade of 10 or higher, a special assets officer analyzes the loan to determine whether the loan is impaired. At that time, the Corporation reassesses the loan to value position in the loan. If the loan is determined to be collateral dependent, specific allocations of the allowance for loan losses are made for the amount of any collateral deficiency. If a collateral deficiency is ultimately deemed to be uncollectible, the amount is charged-off. These loans and related assessments of collateral position are monitored on an individual, case-by-case basis. The Corporation does not monitor loan-to-value ratios on a weighted-average basis for commercial real estate loans having a calculated risk grade of 10 or higher. Nonetheless, there were four commercial real estate loans having a calculated risk grade of 10 or

higher in excess of $5 million as of June 30, 2011. Three of the loans totaled $26.3 million and had a weighted-average loan-to-value ratio of 47.1%. The fourth loan, totaling $6.1 million, is structured as a borrowing base facility secured by numerous rotating lots and single family residences that generally have a loan-to-value of 80% or less. When an individual consumer real estate loan becomes past due by more than 10 days, the assigned relationship manager will begin collection efforts. The Corporation only reassesses the loan to value position in a consumer real estate loan if, during the course of the collections process, it is determined that the loan has become collateral dependent, and any collateral deficiency is recognized as a charge-off to the allowance for loan losses. Accordingly, the Corporation does not monitor loan-to-value ratios on a weighted-average basis for collateral dependent consumer real estate loans.

Generally, a commercial loan, or a portion thereof, is charged-off immediately when it is determined, through the analysis of any available current financial information with regards to the borrower, that the borrower is incapable of servicing unsecured debt, there is little or no prospect for near term improvement and no realistic strengthening action of significance is pending or, in the case of secured debt, when it is determined, through analysis of current information with regards to the Corporation’s collateral position, that amounts due from the borrower are in excess of the calculated current fair value of the collateral. Notwithstanding the foregoing, generally, commercial loans that become past due 180 cumulative days are classified as a loss and charged-off. Generally, a consumer loan, or a portion thereof, is charged-off in accordance with regulatory guidelines which provide that such loans be charged-off when the Corporation becomes aware of the loss, such as from a triggering event that may include new information about a borrower’s intent/ability to repay the loan, bankruptcy, fraud or death, among other things, but in no case should the charge-off exceed specified delinquency timeframes. Such delinquency timeframes state that closed-end retail loans (loans with pre-defined maturity dates, such as real estate mortgages, home equity loans and consumer installment loans) that become past due 120 cumulative days and open-end retail loans (loans that roll-over at the end of each term, such as home equity lines of credit) that become past due 180 cumulative days should be classified as a loss and charged-off.

Net (charge-offs)/recoveries, segregated by class of loans, were as follows:

In assessing the general economic conditions in the State of Texas, management monitors and tracks the Texas Leading Index (“TLI”), which is produced by the Federal Reserve Bank of Dallas. The TLI is a single summary statistic that is designed to signal the likelihood of the Texas economy’s transition from expansion to recession and vice versa. Management believes this index provides a reliable indication of the direction of overall credit quality. The TLI is a composite of the following eight leading indicators: (i) Texas Value of the Dollar, (ii) U.S. Leading Index, (iii) real oil prices (iv) well permits, (v) initial claims for unemployment insurance, (vi) Texas Stock Index, (vii) Help-Wanted Index and (viii) average weekly hours worked in manufacturing. The TLI totaled 122.8 at May 31, 2011 (most recent date available), 118.2 at December 31, 2010 and 113.5 at June 30, 2010. A higher TLI value implies more favorable economic conditions.

Allowance for Loan Losses. The allowance for loan losses is a reserve established through a provision for loan losses charged to expense, which represents management’s best estimate of probable losses that have been incurred within the existing portfolio of loans. The allowance, in the judgment of management, is necessary to reserve for estimated loan losses and risks inherent in the loan portfolio. The Corporation’s allowance for loan loss methodology follows the accounting guidance set forth in U.S. generally accepted accounting principles and the Interagency Policy Statement on the Allowance for Loan and Lease Losses, which was jointly issued by the Corporation’s regulatory agencies. In that regard, the Corporation’s allowance for loan losses includes allowance allocations calculated in accordance with ASC Topic 310, “Receivables” and allowance allocations calculated in accordance with ASC Topic 450, “Contingencies.” Accordingly, the methodology is based on historical loss experience by type of credit and internal risk grade, specific homogeneous risk pools and specific loss allocations, with adjustments for current events and conditions. The Corporation’s process for determining the appropriate level of the allowance for loan losses is designed to account for credit deterioration as it occurs. The provision for loan losses reflects loan quality trends, including the levels of and trends related to non-accrual loans, past due loans, potential problem loans, criticized loans and net charge-offs or recoveries, among other factors. The provision for loan losses also reflects the totality of actions taken on all loans for a particular period. In other words, the amount of the provision reflects not only the necessary increases in the allowance for loan losses related to newly identified criticized loans, but it also reflects actions taken related to other loans including, among other things, any necessary increases or decreases in required allowances for specific loans or loan pools.

The level of the allowance reflects management’s continuing evaluation of industry concentrations, specific credit risks, loan loss and recovery experience, current loan portfolio quality, present economic, political and regulatory conditions and unidentified losses inherent in the current loan portfolio. Portions of the allowance may be allocated for specific credits; however, the entire allowance is available for any credit that, in management’s judgment, should be charged off. While management utilizes its best judgment and information available, the ultimate determination of the appropriate level of the allowance is dependent upon a variety of factors beyond the Corporation’s control, including, among other things, the performance of the Corporation’s loan portfolio, the economy, changes in interest rates and the view of the regulatory authorities toward loan classifications. The Corporation monitors whether or not the allowance for loan loss allocation model, as a whole, calculates an appropriate level of allowance for loan losses that moves in direct correlation to the general macroeconomic and loan portfolio conditions the Corporation experiences over time.

The Corporation’s allowance for loan losses consists of three elements: (i) specific valuation allowances determined in accordance with ASC Topic 310 based on probable losses on specific loans; (ii) historical valuation allowances determined in accordance with ASC Topic 450 based on historical loan loss experience for similar loans with similar characteristics and trends, adjusted, as necessary, to reflect the impact of current conditions; and (iii) general valuation allowances determined in accordance with ASC Topic 450 based on general economic conditions and other risk factors both internal and external to the Corporation.

The allowances established for probable losses on specific loans are based on a regular analysis and evaluation of problem loans. Loans are classified based on an internal credit risk grading process that evaluates, among other things: (i) the obligor’s ability to repay; (ii) the underlying collateral, if any; and (iii) the economic environment and industry in which the borrower operates. This analysis is performed at the relationship manager level for all commercial loans. When a loan has a calculated grade of 10 or higher, a special assets officer analyzes the loan to determine whether the loan is impaired and, if impaired, the need to specifically allocate a portion of the allowance for loan losses to the loan. Specific valuation allowances are determined by analyzing the borrower’s ability to repay amounts owed, collateral deficiencies, the relative risk grade of the loan and economic conditions affecting the borrower’s industry, among other things.

Historical valuation allowances are calculated based on the historical gross loss experience of specific types of loans and the internal risk grade of such loans at the time they were charged-off. The Corporation calculates historical gross loss ratios for pools of similar loans with similar characteristics based on the proportion of actual charge-offs experienced to the total population of loans in the pool. The historical gross loss ratios are periodically updated based on actual charge-off experience. A historical valuation allowance is established for each pool of similar loans based upon the product of the historical gross loss ratio and the total dollar amount of the loans in the pool. The Corporation’s pools of similar loans include similarly risk-graded groups of commercial and industrial loans, commercial real estate loans, consumer real estate loans and consumer and other loans.

The components of the general valuation allowance include (i) the additional reserves allocated to specific loan portfolio segments as a result of applying an environmental risk adjustment factor to the base historical loss allocation and (ii) the additional reserves that are not allocated to specific loan portfolio segments including allocations for groups of similar loans with risk characteristics that exceed certain concentration limits established by management.

The environmental adjustment factor is based upon a more qualitative analysis of risk and is calculated through a survey of senior officers who are involved in credit making decisions at a corporate-wide and/or regional level. On a quarterly basis, survey participants rate the degree of various risks utilizing a numeric scale that translates to varying grades of high, moderate or low levels of risk. The results are then input into a risk-weighting matrix to determine an appropriate environmental risk adjustment factor. The various risks that may be considered in the determination of the environmental adjustment factor include, among other things, (i) the experience, ability and effectiveness of the bank’s lending management and staff; (ii) the effectiveness of the Corporation’s loan policies, procedures and internal controls; (iii) changes in asset quality; (iv) the impact of legislative and governmental influences affecting industry sectors; (v) the effectiveness of the internal loan review function; (vi) the impact of competition on loan structuring and pricing; and (vii) the impact of rising interest rates on portfolio risk. In periods where the surveyed risks are perceived to be higher, the risk-weighting matrix will generally result in a higher environmental adjustment factor, which, in turn will result in higher levels of general valuation allowance allocations. The opposite holds true in periods where the surveyed risks are perceived to be lower. The environmental adjustment factor resulted in additional general valuation allowance allocations to the various loan portfolio segments totaling $12.8 million at June 30, 2011, $9.5 million at December 31, 2010 and $10.2 million at June 30, 2010.

Certain general valuation allowances are not allocated to specific loan portfolio segments and are reported as the unallocated portion of the allowance for loan losses. Included in these general valuation allowances are allocations for groups of similar loans with risk characteristics that exceed certain concentration limits established by management. Concentration risk limits have been established, among other things, for certain industry concentrations, large balance and highly leveraged credit relationships that exceed specified risk grades, and loans originated with policy, credit and/or collateral exceptions that exceed specified risk grades. In addition, during the first quarter of 2011, the Corporation further refined its methodology for the determination of general valuation allowances to also (i) provide additional allocations for loans that did not undergo a separate, independent concurrence review during the underwriting process (generally those loans under $1.0 million at origination), (ii) reduce the minimum balance/commitment threshold for which allocations are made for highly leveraged

credit relationships that exceed specified risk grades, (iii) lower the maximum risk grade thresholds for highly leveraged credit relationships, and (iv) include a reduction factor for recoveries of prior charge-offs to compensate for the fact that historical loss allocations are based upon gross charge-offs rather than net. The net effect of these changes to the Corporation’s methodology for the determination of general valuation allowances did not significantly impact the provision for loan losses recorded during the six months ended June 30, 2011.

The following table presents details of the unallocated portion of the allowance for loan losses.

The Corporation monitors whether or not the allowance for loan loss allocation model, as a whole, calculates an appropriate level of allowance for loan losses that moves in direct correlation to the general macroeconomic and loan portfolio conditions the Corporation experiences over time. In assessing the general macroeconomic trends/conditions, the Corporation analyzes trends in the components of the TLI, as well as any available information related to regional, national and international economic conditions and events and the impact such conditions and events may have on the Corporation and its customers. With regard to assessing loan portfolio conditions, the Corporation analyzes trends in weighted-average portfolio risk-grades, classified and non-performing loans and charge-off activity. In periods where general macroeconomic and loan portfolio conditions are in a deteriorating trend or remain at deteriorated levels, based on historical trends, the Corporation would expect to see the allowance for loan loss allocation model, as a whole, calculate higher levels of required allowances than in periods where general macroeconomic and loan portfolio conditions are in an improving trend or remain at an elevated level, based on historical trends.

The following tables detail activity in the allowance for loan losses by portfolio segment for the three and six months ended June 30, 2011 and 2010. Allocation of a portion of the allowance to one category of loans does not preclude its availability to absorb losses in other categories.

Note 6 - Commitments and Contingencies

Financial Instruments with Off-Balance-Sheet Risk. In the normal course of business, the Corporation enters into various transactions, which, in accordance with generally accepted accounting principles are not included in its consolidated balance sheets. The Corporation enters into these transactions to meet the financing needs of its customers. These transactions include commitments to extend credit and standby letters of credit, which involve, to varying degrees, elements of credit risk and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The Corporation minimizes its exposure to loss under these commitments by subjecting them to credit approval and monitoring procedures.

The Corporation enters into contractual commitments to extend credit, normally with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Substantially all of the Corporation’s commitments to extend credit are contingent upon customers maintaining specific credit standards at the time of loan funding. Standby letters of credit are written conditional commitments issued by the Corporation to guarantee the performance of a customer to a third party. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Corporation would be required to fund the commitment. The maximum potential amount of future payments the Corporation could be required to make is represented by the contractual amount of the commitment. If the commitment were funded, the Corporation would be entitled to seek recovery from the customer. The Corporation’s policies generally require that standby letter of credit arrangements contain security and debt covenants similar to those contained in loan agreements.

The Corporation considers the fees collected in connection with the issuance of standby letters of credit to be representative of the fair value of its obligation undertaken in issuing the guarantee. In accordance with applicable accounting standards related to guarantees, the Corporation defers fees collected in connection with the issuance of standby letters of credit. The fees are then recognized in income proportionately over the life of the standby letter of credit agreement. The deferred standby letter of credit fees represent the fair value of the Corporation’s potential obligations under the standby letter of credit guarantees.

Financial instruments with off-balance-sheet risk were as follows:


	June 30, 2011		December 31, 2010
Commitments to extend credit	$	4,613,486	$	4,528,196
Standby letters of credit		238,889		294,116
Deferred standby letter of credit fees		1,339		1,707

Lease Commitments. The Corporation leases certain office facilities and office equipment under operating leases. Rent expense for all operating leases totaled $5.3 million and $10.8 million for the three and six months ended June 30, 2011 and $5.4 million and $10.7 million for the three and six months ended June 30, 2010. There has been no significant change in the future minimum lease payments payable by the Corporation since December 31, 2010. See the 2010 Form 10-K for information regarding these commitments.

Litigation. The Corporation is subject to various claims and legal actions that have arisen in the course of conducting business. Management does not expect the ultimate disposition of these matters to have a material adverse impact on the Corporation’s financial statements.

Note 7 - Regulatory Matters

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

Quantitative measures established by regulations to ensure capital adequacy require the maintenance of minimum amounts and ratios (set forth in the table below) of total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital to adjusted quarterly average assets (as defined).

Cullen/Frost’s and Frost Bank’s Tier 1 capital consists of shareholders’ equity excluding unrealized gains and losses on securities available for sale, the accumulated gain or loss on effective cash flow hedging derivatives, the net actuarial gain/loss on the Corporation’s defined benefit post-retirement benefit plans, goodwill and other intangible assets. Tier 1 capital for Cullen/Frost also includes $120 million of trust preferred securities issued by an unconsolidated subsidiary trust. Cullen/Frost’s and Frost Bank’s total capital is comprised of Tier 1 capital for each entity plus a permissible portion of the allowance for loan losses. The Corporation’s aggregate $100 million of 5.75% fixed-to-floating rate subordinated notes are not included in Tier 1 capital but are included in total capital of Cullen/Frost.

The Tier 1 and total capital ratios are calculated by dividing the respective capital amounts by risk-weighted assets. Risk-weighted assets are calculated based on regulatory requirements and include total assets, excluding goodwill and other intangible assets, allocated by risk weight category, and certain off-balance-sheet items (primarily loan commitments). The leverage ratio is calculated by dividing Tier 1 capital by adjusted quarterly average total assets, which exclude goodwill and other intangible assets.

Actual and required capital ratios for Cullen/Frost and Frost Bank were as follows:


	Actual					Minimum Required for Capital Adequacy Purposes					Required to be Well Capitalized Under Prompt Corrective Action Regulations
	Capital Amount		Ratio			Capital Amount		Ratio			Capital Amount		Ratio
June 30, 2011
Total Capital to Risk-Weighted Assets
Cullen/Frost	$	1,784,505		16.42	%	$	869,328		8.00	%		N/A		N/A
Frost Bank		1,608,202		14.81			868,684		8.00		$	1,085,856		10.00	%

Cullen/Frost		1,494,375		8.68			688,880		4.00			N/A		N/A
Frost Bank		1,432,661		8.33			688,196		4.00			860,246		5.00

Cullen/Frost believes that, as of June 30, 2011, its bank subsidiary, Frost Bank, was “well capitalized” based on the ratios presented above.

Cullen/Frost is subject to the regulatory capital requirements administered by the Federal Reserve, while Frost Bank is subject to the regulatory capital requirements administered by the Office of the Comptroller of the Currency and the Federal Deposit Insurance Corporation. Regulatory authorities can initiate certain mandatory actions if Cullen/Frost or Frost Bank fail to meet the minimum capital requirements, which could have a direct material effect on the Corporation’s financial statements. Management believes, as of June 30, 2011, that Cullen/Frost and Frost Bank meet all capital adequacy requirements to which they are subject.

Dividend Restrictions. In the ordinary course of business, Cullen/Frost is dependent upon dividends from Frost Bank to provide funds for the payment of dividends to shareholders and to provide for other cash requirements. Banking regulations may limit the amount of dividends that may be paid. Approval by regulatory authorities is required if the effect of dividends declared would cause the regulatory capital of Frost Bank to fall below specified minimum levels. Approval is also required if dividends declared exceed the net profits for that year combined with the retained net profits for the preceding two years. Under the foregoing dividend restrictions and while maintaining its “well capitalized” status, at June 30, 2011, Frost Bank could pay aggregate dividends of up to $255.2 million to Cullen/Frost without prior regulatory approval.

Trust Preferred Securities. In accordance with the applicable accounting standard related to variable interest entities, the accounts of the Corporation’s wholly owned subsidiary trust, Cullen/Frost Capital Trust II, have not been included in the Corporation’s consolidated financial statements. However, the $120.0 million in trust preferred securities issued by this subsidiary trust have been included in the Tier 1 capital of Cullen/Frost for regulatory capital purposes pursuant to guidance from the Federal Reserve. On July 21, 2010, financial regulatory reform legislation entitled the “Dodd-Frank Wall Street Reform and Consumer Protection Act” (the “Dodd-Frank Act”) was signed into law. Certain provisions of the Dodd-Frank Act will require the Corporation to deduct, over three years beginning on January 1, 2013, all trust preferred securities from the Corporation’s Tier 1 capital. Nonetheless, excluding trust preferred securities from Tier 1 capital at June 30, 2011 would not affect the Corporation’s ability to meet all capital adequacy requirements to which it is subject.

Note 8 - Derivative Financial Instruments

The fair value of derivative positions outstanding is included in accrued interest receivable and other assets and accrued interest payable and other liabilities in the accompanying consolidated balance sheets and in the net change in each of these financial statement line items in the accompanying consolidated statements of cash flows.

Interest Rate Derivatives. The Corporation utilizes interest rate swaps, caps and floors to mitigate exposure to interest rate risk and to facilitate the needs of its customers. The Corporation’s objectives for utilizing these derivative instruments is described below:

The Corporation has entered into certain interest rate swap contracts that are matched to specific fixed-rate commercial loans or leases that the Corporation has entered into with its customers. These contracts have been designated as hedging instruments to hedge the risk of changes in the fair value of the underlying commercial loan/lease due to changes in interest rates. The related contracts are structured so that the notional amounts reduce over time to generally match the expected amortization of the underlying loan/lease.

During 2007, the Corporation entered into three interest rate swap contracts on variable-rate loans with a total notional amount of $1.2 billion. The interest rate swap contracts were designated as hedging instruments in cash flow hedges with the objective of protecting the overall cash flows from the Corporation’s monthly interest receipts on a rolling portfolio of $1.2 billion of variable-rate loans outstanding throughout the 84-month period beginning in October 2007 and ending in October 2014 from the risk of variability of those cash flows such that the yield on the underlying loans would remain constant. As further discussed below, the Corporation terminated portions of the hedges and settled portions of the interest rate swap contracts during November 2009 and terminated the remaining portions of the hedges and settled the remaining portions of the interest rate swap contracts during November 2010. Under the initial hedge relationship, the desired constant yield was 7.559% in the case of the first contract (underlying loan pool totaling $650.0 million carrying an interest rate equal to Prime), 8.059% in the case of the second contract (underlying loan pool totaling $230.0 million carrying an interest rate equal to Prime plus a margin of 50 basis points) and 8.559% in the case of the third contract (underlying loan pool totaling $320.0 million carrying an interest rate equal to Prime plus a margin of 100 basis points). Under the swaps, the Corporation received a fixed interest rate of 7.559% and paid a variable interest rate equal to the daily Federal Reserve Statistical Release H-15 Prime Rate (Prime), with monthly settlements.

As stated above, during November 2009, the Corporation settled portions of two of the interest rate swap contracts having a total notional amount of $400.0 million and concurrently terminated the hedges related to the interest cash flows on a rolling portfolio of $400.0 million of variable rate loans. The terminated hedges had underlying loan pools totaling $300.0 million carrying an interest rate equal to Prime and $100.0 million carrying an interest rate equal to Prime plus a margin of 50 basis points. In November 2010, the Corporation settled the remaining interest rate swap contracts having a total notional amount of $800.0 million and concurrently terminated the hedges related to the interest cash flows on a rolling portfolio of $800.0 million of variable rate loans. The terminated hedges had underlying loan pools totaling $350.0 million carrying an interest rate equal to Prime, $130.0 million carrying an interest rate equal to Prime plus a margin of 50 basis points and $320.0 million carrying an interest rate equal to Prime plus a margin of 100 basis points. The deferred accumulated after-tax gain applicable to the settled interest rate contracts included in accumulated other comprehensive income totaled $80.6 million at June 30, 2011. The deferred gain will be reclassified into earnings during future periods when the formerly hedged transactions impact future earnings.

In October 2008, the Corporation entered into an interest rate swap contract on junior subordinated deferrable interest debentures with a total notional amount of $120.0 million. The interest rate swap contract was designated as a hedging instrument in a cash flow hedge with the objective of protecting the quarterly interest payments on the Corporation’s $120.0 million of junior subordinated deferrable interest debentures issued to Cullen/Frost Capital Trust II throughout the five-year period beginning in December 2008 and ending in December 2013 from the risk of variability of those payments resulting from changes in the three-month LIBOR interest rate. Under the swap, the Corporation will pay a fixed interest rate of 5.47% and receive a variable interest rate of three-month LIBOR plus a margin of 1.55% on a total notional amount of $120.0 million, with quarterly settlements.

The Corporation has entered into certain interest rate swap, cap and floor contracts that are not designated as hedging instruments. These derivative contracts relate to transactions in which the Corporation enters into an interest rate swap, cap and/or floor with a customer while at the same time entering into an offsetting interest rate swap, cap and/or floor with another financial institution. In connection with each swap transaction, the Corporation agrees to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on a similar notional amount at a fixed interest rate. At the same time, the Corporation agrees to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. The transaction allows the Corporation’s customer to effectively convert a variable rate loan to a fixed rate. Because the Corporation acts as an intermediary for its customer, changes in the fair value of the underlying derivative contracts for the most part offset each other and do not significantly impact the Corporation’s results of operations.

The notional amounts and estimated fair values of interest rate derivative contracts outstanding at June 30, 2011 and December 31, 2010 are presented in the following table. The Corporation obtains dealer quotations to value its interest rate derivative contracts designated as hedges of cash flows, while the fair values of other interest rate derivative contracts are estimated utilizing internal valuation models with observable market data inputs.


	June 30, 2011					December 31, 2010
	Notional Amount		Estimated Fair Value			Notional Amount		Estimated Fair Value
Interest rate derivatives designated as hedges of fair value:
Commercial loan/lease interest rate swaps	$	90,626	$	(7,496	)	$	104,088	$	(8,350	)

Interest rate derivatives designated as hedges of cash flows:
Interest rate swap on junior subordinated deferrable interest debentures		120,000		(9,353	)		120,000		(9,895	)

Non-hedging interest rate derivatives:
Commercial loan/lease interest rate swaps		582,074		44,270			593,792		44,335
Commercial loan/lease interest rate swaps		582,074		(44,474	)		593,792		(44,666	)
Commercial loan/lease interest rate caps		20,000		226			20,000		388
Commercial loan/lease interest rate caps		20,000		(226	)		20,000		(388	)

The weighted-average rates paid and received for interest rate swaps outstanding at June 30, 2011 were as follows:


	Weighted-Average
	Interest Rate Paid			Interest Rate Received
Interest rate swaps:
Fair value hedge commercial loan/lease interest rate swaps		4.49	%		0.19	%
Cash flow hedge interest rate swaps on junior subordinated deferrable interest debentures		5.47			1.80
Non-hedging interest rate swaps		5.08			1.80
Non-hedging interest rate swaps		1.80			5.08

The weighted-average strike rate for outstanding interest rate caps was 3.10% at June 30, 2011.

Commodity Derivatives. The Corporation enters into commodity swaps and option contracts that are not designated as hedging instruments primarily to accommodate the business needs of its customers. Upon the origination of a commodity swap or option contract with a customer, the Corporation simultaneously enters into an offsetting contract with a third party to mitigate the exposure to fluctuations in commodity prices.

The notional amounts and estimated fair values of commodity derivative positions outstanding are presented in the following table. The Corporation obtains dealer quotations to value its commodity derivative positions.


			June 30, 2011					December 31, 2010
	Notional Units		Notional Amount		Estimated Fair Value			Notional Amount		Estimated Fair Value
Non-hedging commodity swaps:
Oil		Barrels		483	$	2,318			321	$	2,502
Oil		Barrels		483		(2,210	)		321		(2,428	)
Natural gas		MMBTUs		4,265		1,145			510		195
Natural gas		MMBTUs		4,265		(1,022	)		510		(174	)
Non-hedging commodity options:
Oil		Barrels		2,473		13,916			1,288		7,706
Oil		Barrels		2,473		(13,916	)		1,288		(7,706	)
Natural gas		MMBTUs		2,400		2,039			3,820		3,774
Natural gas		MMBTUs		2,400		(2,039	)		3,820		(3,774	)

Foreign Currency Derivatives. The Corporation enters into foreign currency forward contracts that are not designated as hedging instruments primarily to accommodate the business needs of its customers. Upon the origination of a foreign currency denominated transaction with a customer, the Corporation simultaneously enters into an offsetting contract with a third party to negate the exposure to fluctuations in foreign currency exchange rates. The Corporation also utilizes foreign currency forward contracts that are not designated as hedging instruments to mitigate the economic effect of fluctuations in foreign currency exchange rates on certain short-term, non-U.S. dollar denominated loans. The notional amounts and fair values of open foreign currency forward contracts were not significant at June 30, 2011 and December 31, 2010.

Gains, Losses and Derivative Cash Flows. For fair value hedges, the changes in the fair value of both the derivative hedging instrument and the hedged item are included in other non-interest income or other non-interest expense. The extent that such changes in fair value do not offset represents hedge ineffectiveness. Net cash flows from interest rate swaps on commercial loans/leases designated as hedging instruments in effective hedges of fair value are included in interest income on loans. For cash flow hedges, the effective portion of the gain or loss due to changes in the fair value of the derivative hedging instrument is included in other comprehensive income, while the ineffective portion (indicated by the excess of the cumulative change in the fair value of the derivative over that which is necessary to offset the cumulative change in expected future cash flows on the hedge transaction) is included in other non-interest income or other non-interest expense. Net cash flows from interest rate swaps on variable-rate loans designated as hedging instruments in effective hedges of cash flows and the reclassification from other comprehensive income of deferred gains associated with the termination of those hedges are included in interest income on loans. Net cash flows from the interest rate swap on junior subordinated deferrable interest debentures designated as a hedging instrument in an effective hedge of cash flows are included in interest expense on junior subordinated deferrable interest debentures. For non-hedging derivative instruments, gains and losses due to changes in fair value and all cash flows are included in other non-interest income and other non-interest expense.

Amounts included in the consolidated statements of income related to interest rate derivatives designated as hedges of fair value were as follows:


	Three Months Ended June 30,						Six Months Ended June 30,
	2011			2010			2011			2010
Commercial loan/lease interest rate swaps:
Amount of gain (loss) included in interest income on loans	$	(969	)	$	(1,318	)	$	(1,974	)	$	(2,734	)
Amount of (gain) loss included in other non-interest expense		6			(97	)		(3	)		(91	)

Amounts included in the consolidated statements of income and in other comprehensive income for the period related to interest rate derivatives designated as hedges of cash flows were as follows:


	Three Months Ended June 30,						Six Months Ended June 30,
	2011			2010			2011			2010
Interest rate swaps/caps/floors on variable-rate loans:
Amount reclassified from accumulated other comprehensive income to interest income on loans	$	9,345		$	11,033		$	18,690		$	21,970
Amount of gain (loss) recognized in other comprehensive income		—			34,959			—			50,731
Interest rate swaps on junior subordinated deferrable interest debentures:
Amount reclassified from accumulated other comprehensive income to interest expense on junior subordinated deferrable interest debentures		1,100			1,084			2,186			2,195
Amount of gain (loss) recognized in other comprehensive income		(1,716	)		(3,089	)		(1,651	)		(5,566	)

No ineffectiveness related to interest rate derivatives designated as hedges of cash flows was recognized in the consolidated statements of income during the reported periods. The accumulated net after-tax gain related to effective cash flow hedges included in accumulated other comprehensive income totaled $74.8 million at June 30, 2011 and $86.6 million at December 31, 2010. The Corporation currently expects approximately $10.7 million of the net after-tax gain related to effective cash flow hedges included in accumulated other comprehensive income at June 30, 2011 will be reclassified into earnings during the remainder of 2011. This amount represents management’s best estimate given current expectations about market interest rates and volumes related to loan pools underlying the terminated cash flow hedges. Because actual market interest rates and volumes related to loan pools underlying the terminated cash flow hedges may differ from management’s expectations, there can be no assurance as to the ultimate amount that will be reclassified into earnings during 2011.

As stated above, the Corporation enters into non-hedge related derivative positions primarily to accommodate the business needs of its customers. Upon the origination of a derivative contract with a customer, the Corporation simultaneously enters into an offsetting derivative contract with a third party. The Corporation recognizes immediate income based upon the difference in the bid/ask spread of the underlying transactions with its customers and the third party. Because the Corporation acts only as an intermediary for its customer, subsequent changes in the fair value of the underlying derivative contracts for the most part offset each other and do not significantly impact the Corporation’s results of operations.

Amounts included in the consolidated statements of income related to non-hedging interest rate and commodity derivative instruments are presented in the table below. Amounts included in the consolidated statements of income related to foreign currency derivatives during the reported periods were not significant.


	Three Months Ended June 30,					Six Months Ended June 30,
	2011			2010		2011			2010
Non-hedging interest rate derivatives:
Other non-interest income	$	462		$	892	$	736		$	1,594
Other non-interest expense		(89	)		59		(128	)		78
Non-hedging commodity derivatives:
Other non-interest income		79			26		462			46

Counterparty Credit Risk. Derivative contracts involve the risk of dealing with both bank customers and institutional derivative counterparties and their ability to meet contractual terms. Institutional counterparties must have an investment grade credit rating and be approved by the Corporation’s Asset/Liability Management Committee. The Corporation’s credit exposure on interest rate swaps is limited to the net favorable value and interest payments of all swaps by each counterparty, while the Corporation’s credit exposure on commodity swaps/options is limited to the net favorable value of all swaps/options by each counterparty. Credit exposure may be reduced by the amount of collateral pledged by the counterparty. There are no credit-risk-related contingent features associated with any of the Corporation’s derivative contracts. Certain derivative contracts with upstream financial institution counterparties may be terminated with respect to a party in the transaction, if such party does not have at least a minimum level rating assigned to either its senior unsecured long-term debt or its deposit obligations by certain third-party rating agencies.

The Corporation’s credit exposure relating to interest rate swaps and commodity swaps/options with bank customers was approximately $45.1 million at June 30, 2011. This credit exposure is partly mitigated as transactions with customers are generally secured by the collateral, if any, securing the underlying transaction being hedged. The Corporation had no credit exposure, net of collateral pledged, relating to interest rate swaps and commodity swaps/options with upstream financial institution counterparties at June 30, 2011. Collateral levels for upstream financial institution counterparties are monitored and adjusted as necessary.

The aggregate fair value of securities posted as collateral by the Corporation related to derivative contracts totaled $52.8 million at June 30, 2011. At such date, the Corporation also had $10.0 million in cash collateral on deposit with other financial institution counterparties.

Note 9 - Earnings Per Common Share

Earnings per common share is computed using the two-class method. Basic earnings per common share is computed by dividing net earnings allocated to common stock by the weighted-average number of common shares outstanding during the applicable period, excluding outstanding participating securities. Participating securities include non-vested stock awards/stock units and deferred stock units, though no actual shares of common stock related to non-vested stock units and deferred stock units have been issued. Non-vested stock awards/stock units and deferred stock units are considered participating securities because holders of these securities receive non-forfeitable dividends at the same rate as holders of the Corporation’s common stock. Diluted earnings per common share is computed using the weighted-average number of shares determined for the basic earnings per common share computation plus the dilutive effect of stock compensation using the treasury stock method.

The following table presents a reconciliation of the number of shares used in the calculation of basic and diluted earnings per common share.


	Three Months Ended June 30,				Six Months Ended June 30,
	2011		2010		2011		2010

Net deferred tax liabilities totaled $91.5 million at June 30, 2011 and $65.2 million at December 31, 2010. No valuation allowance was recorded against deferred tax assets at June 30, 2011 as management believes that it is more likely than not that all of the deferred tax assets will be realized because they were supported by recoverable taxes paid in prior years. There were no unrecognized tax benefits during any of the reported periods.

The Corporation files income tax returns in the U.S. federal jurisdiction. The Company is no longer subject to U.S. federal income tax examinations by tax authorities for years before 2007.

Note 14 - Operating Segments

The Corporation is managed under a matrix organizational structure whereby significant lines of business, including Banking and the Financial Management Group (FMG), overlap a regional reporting structure. The regions are primarily based upon geographic location and include Austin, Corpus Christi, Dallas, Fort Worth, Houston, Rio Grande Valley, San Antonio and Statewide. The Corporation is primarily managed based on the line of business structure. In that regard, all regions have the same lines of business, which have the same product and service offerings, have similar types and classes of customers and utilize similar service delivery methods. Pricing guidelines for products and services are the same across all regions. The regional reporting structure is primarily a means to scale the lines of business to provide a local, community focus for customer relations and business development.

The Corporation has two primary operating segments, Banking and FMG, that are delineated by the products and services that each segment offers. The Banking operating segment includes both commercial and consumer banking services, Frost Insurance Agency and Frost Securities, Inc. Commercial banking services are provided to corporations and other business clients and include a wide array of lending and cash management products. Consumer banking services include direct lending and depository services. Frost Insurance Agency provides insurance brokerage services to individuals and businesses covering corporate and personal property and casualty products, as well as group health and life insurance products. Frost Securities, Inc. provides advisory and private equity services to middle market companies. The FMG operating segment includes fee-based services within private trust, retirement services, and financial management services, including personal wealth management and brokerage services. The third operating segment, Non-Banks, is for the most part the parent holding company, as well as certain other insignificant non-bank subsidiaries of the parent that, for the most part, have little or no activity. The parent company’s principal activities include the direct and indirect ownership of the Corporation’s banking and non-banking subsidiaries and the issuance of debt and equity. Its principal source of revenue is dividends from its subsidiaries.

The accounting policies of each reportable segment are the same as those of the Corporation except for the following items, which impact the Banking and FMG segments: (i) expenses for consolidated back-office operations and general overhead-type expenses such as executive administration, accounting and internal audit are allocated to operating segments based on estimated uses of those services, (ii) income tax expense for the individual segments is calculated essentially at the statutory rate, and (iii) the parent company records the tax expense or benefit necessary to reconcile to the consolidated total.

The Corporation uses a match-funded transfer pricing process to assess operating segment performance. The process helps the Corporation to (i) identify the cost or opportunity value of funds within each business segment, (ii) measure the profitability of a particular business segment by relating appropriate costs to revenues, (iii) evaluate each business segment in a manner consistent with its economic impact on consolidated earnings, and (iv) enhance asset and liability pricing decisions.

Summarized operating results by segment were as follows:


	Banking		FMG		Non-Banks			Consolidated

Note 15 - Fair Value Measurements

The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. In estimating fair value, the Corporation utilizes valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. Such valuation techniques are consistently applied. Inputs to valuation techniques include the assumptions that market participants would use in pricing an asset or liability. ASC Topic 820 establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

•

Level 1 Inputs - Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

•

Level 2 Inputs - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

•

Level 3 Inputs - Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.

In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and the Corporation’s creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. The Corporation’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Corporation’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Furthermore, the reported fair value amounts have not been comprehensively revalued since the presentation dates, and therefore, estimates of fair value after the balance sheet date may differ significantly from the amounts presented herein. A more detailed description of the valuation methodologies used for assets and liabilities measured at fair value is set forth in the 2010 Form 10-K. Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally coincides with the Corporation’s monthly and/or quarterly valuation process.

Financial Assets and Financial Liabilities: The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis as of June 30, 2011 and December 31, 2010, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value:

The following table reconciles the beginning and ending balances of derivative assets measured at fair value on a recurring basis using significant unobservable (Level 3) inputs during the six months ended June 30, 2011 and 2010:


	Six Months Ended June 30,

Certain financial assets and financial liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). Financial assets measured at fair value on a non-recurring basis during the six months ended June 30, 2011 and 2010 include certain impaired loans reported at the fair value of the underlying collateral if repayment is expected solely from the collateral. Collateral values are estimated using Level 2 inputs based on observable market data or Level 3 inputs based on customized discounting criteria. The following table presents impaired loans that were remeasured and reported at fair value through a specific valuation allowance allocation of the allowance for loan losses based upon the fair value of the underlying collateral during the six months ended June 30, 2011 and 2010.


	Six Months Ended June 30, 2011						Six Months Ended June 30, 2010
	Level 2			Level 3			Level 2			Level 3
Carrying value of impaired loans	$	10,420		$	3,871		$	15,688		$	19,879

Fair value	$	2,390		$	989		$	12,737		$	13,647

Non-Financial Assets and Non-Financial Liabilities: The Corporation has no non-financial assets or non-financial liabilities measured at fair value on a recurring basis. Certain non-financial assets measured at fair value on a non-recurring basis include foreclosed assets (upon initial recognition or subsequent impairment), non-financial assets and non-financial liabilities measured at fair value in the second step of a goodwill impairment test, and intangible assets and other non-financial long-lived assets measured at fair value for impairment assessment. Non-financial assets measured at fair value on a non-recurring basis during the six months ended June 30, 2011 and 2010 include certain foreclosed assets which, upon initial recognition, were remeasured and reported at fair value through a charge-off to the allowance for loan losses and certain foreclosed assets which, subsequent to their initial recognition, were remeasured at fair value through a write-down included in other non-interest expense. The fair value of a foreclosed asset is estimated using Level 2 inputs based on observable market data or Level 3 inputs based on customized discounting criteria. During the reported periods, all fair value measurements for foreclosed assets utilized Level 2 inputs.

The following table presents foreclosed assets that were remeasured and reported at fair value:


	Six Months Ended June 30,
	2011			2010
Foreclosed assets remeasured at initial recognition:
Carrying value of foreclosed assets prior to remeasurement	$	16,595		$	13,160
Charge-offs recognized in the allowance for loan losses		(3,042	)		(2,367	)

Fair value	$	13,553		$	10,793

Foreclosed assets remeasured subsequent to initial recognition:
Carrying value of foreclosed assets prior to remeasurement	$	3,058		$	3,043
Write-downs included in other non-interest expense		(803	)		(1,054	)

Fair value	$	2,255		$	1,989

Charge-offs recognized upon loan foreclosures are generally offset by general or specific allocations of the allowance for loan losses and generally do not, and did not during the reported periods, significantly impact the Corporation’s provision for loan losses. Regulatory guidelines require the Corporation to reevaluate the fair value of other real estate owned on at least an annual basis. While the Corporation’s policy is to comply with the regulatory guidelines, the Corporation’s general practice is to reevaluate the fair value of other real estate owned on a quarterly basis. Thus, appraisals are never considered to be outdated, and the Corporation does not make any adjustments to the appraised values. The fair value of other real estate owned is monitored/evaluated by a third-party service and reviewed with management on a quarterly basis.

FASB ASC Topic 825 requires disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-recurring basis. A detailed description of the valuation methodologies used in estimating the fair value of financial instruments is set forth in the 2010 Form 10-K.

The estimated fair values of financial instruments were as follows:


	June 30, 2011				December 31, 2010
	Carrying Amount		Estimated Fair Value		Carrying Amount		Estimated Fair Value
Financial assets:
Cash and cash equivalents	$	3,420,561	$	3,420,561	$	2,820,977	$	2,820,977

Accrued interest payable		9,152		9,152		9,991		9,991

Under ASC Topic 825, entities may choose to measure eligible financial instruments at fair value at specified election dates. The fair value measurement option (i) may be applied instrument by instrument, with certain exceptions, (ii) is generally irrevocable and (iii) is applied only to entire instruments and not to portions of instruments. Unrealized gains and losses on items for which the fair value measurement option has been elected must be reported in earnings at each subsequent reporting date. During the reported periods, the Corporation had no financial instruments measured at fair value under the fair value measurement option.

Note 16 - Accounting Standards Updates

ASU No. 2010-20, “Receivables (Topic 310) - Disclosures about the Credit Quality of Financing Receivables and the Allowance for Credit Losses.” ASU 2010-20 requires entities to provide disclosures designed to facilitate financial statement users’ evaluation of (i) the nature of credit risk inherent in the entity’s portfolio of financing receivables, (ii) how that risk is analyzed and assessed in arriving at the allowance for credit losses and (iii) the changes and reasons for those changes in the allowance for credit losses. Disclosures must be disaggregated by portfolio segment, the level at which an entity develops and documents a systematic method for determining its allowance for credit losses, and class of financing receivable, which is generally a disaggregation of portfolio segment. The required disclosures include, among other things, a rollforward of the allowance for credit losses as well as information about modified, impaired, non-accrual and past due loans and credit quality indicators. ASU 2010-20 became effective for the Corporation’s financial statements as of December 31, 2010, as it relates to disclosures required as of the end of a reporting period. Disclosures that relate to activity during a reporting period became effective for the Corporation’s financial statements beginning on January 1, 2011. ASU 2011-01, “Receivables (Topic 310) - Deferral of the Effective Date of Disclosures about Troubled Debt Restructurings in Update No. 2010-20,” temporarily deferred the effective date for disclosures related to troubled debt restructurings to coincide with the effective date of the then proposed ASU 2011-02, “Receivables (Topic 310) - A Creditor’s Determination of Whether a Restructuring Is a Troubled Debt Restructuring,” which is further discussed below.

ASU No. 2010-28, “Intangibles - Goodwill and Other (Topic 350) - When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts.” ASU 2010-28 modifies Step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. In determining

whether it is more likely than not that a goodwill impairment exists, an entity should consider whether there are any adverse qualitative factors indicating that an impairment may exist such as if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. ASU 2010-28 became effective for the Corporation on January 1, 2011 and did not have a significant impact on the Corporation’s financial statements.

ASU No. 2011-02, “Receivables (Topic 310) - A Creditor’s Determination of Whether a Restructuring Is a Troubled Debt Restructuring.” ASU 2011-02 clarifies which loan modifications constitute troubled debt restructurings and is intended to assist creditors in determining whether a modification of the terms of a receivable meets the criteria to be considered a troubled debt restructuring, both for purposes of recording an impairment loss and for disclosure of troubled debt restructurings. In evaluating whether a restructuring constitutes a troubled debt restructuring, a creditor must separately conclude, under the guidance clarified by ASU 2011-02, that both of the following exist: (a) the restructuring constitutes a concession; and (b) the debtor is experiencing financial difficulties. ASU 2011-02 will be effective for the Corporation on July 1, 2011, and applies retrospectively to restructurings occurring on or after January 1, 2011. Adoption of ASU 2011-02 is not expected to have a significant impact on the Corporation’s financial statements.

ASU No. 2011-03, “Transfers and Servicing (Topic 860) - Reconsideration of Effective Control for Repurchase Agreements.” ASU 2011-03 is intended to improve financial reporting of repurchase agreements and other agreements that both entitle and obligate a transferor to repurchase or redeem financial assets before their maturity. ASU 2011-03 removes from the assessment of effective control (i) the criterion requiring the transferor to have the ability to repurchase or redeem the financial assets on substantially the agreed terms, even in the event of default by the transferee, and (ii) the collateral maintenance guidance related to that criterion. ASU 2011-03 will be effective for the Corporation on January 1, 2012 and is not expected to have a significant impact on the Corporation’s financial statements.

ASU 2011-04, “Fair Value Measurement (Topic 820) - Amendments to Achieve Common Fair Value Measurements and Disclosure Requirements in U.S. GAAP and IFRSs.” ASU 2011-04 amends Topic 820, “Fair Value Measurements and Disclosures,” to converge the fair value measurement guidance in U.S. generally accepted accounting principles and International Financial Reporting Standards. ASU 2011-04 clarifies the application of existing fair value measurement requirements, changes certain principles in Topic 820 and requires additional fair value disclosures. ASU 2011-04 is effective for annual periods beginning after December 15, 2011, and is not expected to have a significant impact on the Corporation’s financial statements.

ASU 2011-05, “Comprehensive Income (Topic 220) - Presentation of Comprehensive Income.” ASU 2011-05 amends Topic 220, “Comprehensive Income,” to require that all nonowner changes in stockholders’ equity be presented in either a single continuous statement of comprehensive income or in two separate but consecutive statements. Additionally, ASU 2011-05 requires entities to present, on the face of the financial statements, reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement or statements where the components of net income and the components of other comprehensive income are presented. The option to present components of other comprehensive income as part of the statement of changes in stockholders’ equity was eliminated. ASU 2011-05 is effective for annual periods beginning after December 15, 2011, and is not expected to have a significant impact on the Corporation’s financial statements.

Application of Critical Accounting Policies and Accounting Estimates

The accounting and reporting policies followed by the Corporation conform, in all material respects, to accounting principles generally accepted in the United States and to general practices within the financial services industry. The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. While the Corporation bases estimates on historical experience, current information and other factors deemed to be relevant, actual results could differ from those estimates.

The Corporation considers accounting estimates to be critical to reported financial results if (i) the accounting estimate requires management to make assumptions about matters that are highly uncertain and (ii) different estimates that management reasonably could have used for the accounting estimate in the current period, or changes in the accounting estimate that are reasonably likely to occur from period to period, could have a material impact on the Corporation’s financial statements. Accounting policies related to the allowance for loan losses are considered to be critical, as these policies involve considerable subjective judgment and estimation by management.

For additional information regarding critical accounting policies, refer to Note 1 - Summary of Significant Accounting Policies in the notes to consolidated financial statements and the sections captioned “Application of Critical Accounting Policies” and “Allowance for Loan Losses” in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in the 2010 Form 10-K. During the first quarter of 2011, the Corporation further refined its methodology for the determination of the general valuation allowance component of the allowance for loan losses. See Note 3 - Loans in the accompanying notes to consolidated financial statements for a discussion of the changes.

Overview

A discussion of the Corporation’s results of operations is presented below. Certain reclassifications have been made to make prior periods comparable. Taxable-equivalent adjustments are the result of increasing income from tax-free loans and securities by an amount equal to the taxes that would be paid if the income were fully taxable based on a 35% federal income tax rate, thus making tax-exempt asset yields comparable to taxable asset yields.

Results of Operations

Net income totaled $55.7 million, or $0.91 diluted per share, for the three months ended June 30, 2011 compared to $52.9 million, or $0.87 diluted per share, for the three months ended June 30, 2010 and $51.9 million, or $0.85 diluted per share, for the three months ended March 31, 2011. Net income totaled $107.6 million, or $1.75 diluted per share, for the six months ended June 30, 2011 compared to $100.7 million, or $1.66 diluted per share, for the six months ended June 30, 2010.

Selected income statement data and other selected data for the comparable periods was as follows:

Net income increased $2.8 million, or 5.3%, for the three months ended June 30, 2011 and increased $6.9 million, or 6.8%, for the six months ended June 30, 2011 compared to the same periods in 2010. The increase during the three months ended June 30, 2011 was primarily the result of a $2.4 million increase in net interest income, a $2.0 million decrease in income tax expense and a $860 thousand increase in non-interest income partly offset by a $2.1 million increase in non-interest expense and a $335 thousand increase in the provision for loan losses. The increase during the six months ended June 30, 2011 was primarily the result of a $6.6 million increase in net interest income, a $3.8 million decrease in the provision for loan losses, a $2.3 million decrease in income tax expense and a $1.8 million increase in non-interest income partly offset by a $7.6 million increase in non-interest expense.

Net income for the second quarter of 2011 increased $3.8 million, or 7.2%, from the first quarter of 2011. The increase was primarily the result of a $3.3 million decrease in non-interest expense, a $2.6 million increase in net interest income and a $465 thousand decrease in the provision for loan losses partly offset by a $1.5 million decrease in non-interest income and a $1.0 million increase in income tax expense.

Details of the changes in the various components of net income are further discussed below.

Net Interest Income

Net interest income is the difference between interest income on earning assets, such as loans and securities, and interest expense on liabilities, such as deposits and borrowings, which are used to fund those assets. Net interest income is the Corporation’s largest source of revenue, representing 66.7% of total revenue during the first six months of 2011. Net interest margin is the ratio of taxable-equivalent net interest income to average earning assets for the period. The level of interest rates and the volume and mix of earning assets and interest-bearing liabilities impact net interest income and net interest margin.

The Federal Reserve influences the general market rates of interest, including the deposit and loan rates offered by many financial institutions. The Corporation’s loan portfolio is significantly affected by changes in the prime interest rate. The prime interest rate, which is the rate offered on loans to borrowers with strong credit, remained at 3.25% for the entire year in

2010 and through the second quarter of 2011. The Corporation’s loan portfolio is also impacted, to a lesser extent, by changes in the London Interbank Offered Rate (LIBOR). At June 30, 2011, the one-month and three-month U.S. dollar LIBOR rates were 0.19% and 0.25%, respectively, while at June 30, 2010, the one-month and three-month U.S. dollar LIBOR rates were 0.35% and 0.53%, respectively. The intended federal funds rate, which is the cost of immediately available overnight funds, remained at zero to 0.25% for the entire year in 2010 and through the second quarter of 2011.

The Corporation’s balance sheet has historically been asset sensitive, meaning that earning assets generally reprice more quickly than interest-bearing liabilities. Therefore, the Corporation’s net interest margin was likely to increase in sustained periods of rising interest rates and decrease in sustained periods of declining interest rates. During the fourth quarter of 2007, in an effort to make the Corporation’s balance sheet less sensitive to changes in interest rates, the Corporation entered into various interest rate swaps which effectively converted certain variable-rate loans into fixed-rate instruments for a period of time. During the fourth quarter of 2008, the Corporation also entered into an interest rate swap which effectively converted variable-rate debt into fixed-rate debt for a period of time. As a result of these actions, the Corporation’s balance sheet was more interest-rate neutral and changes in interest rates had a less significant impact on the Corporation’s net interest margin than would have otherwise been the case. During the fourth quarter of 2009, a portion of the interest rate swaps on variable-rate loans were terminated, while the remaining interest rate swaps on variable-rate loans were terminated during the fourth quarter of 2010. These actions increased the asset sensitivity of the Corporation’s balance sheet. See Note 8 - Derivative Financial Instruments in the accompanying notes to consolidated financial statements included elsewhere in this report for additional information related to these interest rate swaps.

The Corporation is primarily funded by core deposits, with non-interest-bearing demand deposits historically being a significant source of funds. This lower-cost funding base is expected to have a positive impact on the Corporation’s net interest income and net interest margin in a rising interest rate environment. As discussed in the section captioned “Supervision and Regulation” included in Item 1. Business, of the 2010 Form 10-K, the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) repealed the federal prohibitions on the payment of interest on demand deposits, thereby permitting depository institutions to pay interest on business transaction and other accounts beginning July 21, 2011. Although the ultimate impact of this legislation on the Corporation has not yet been determined, the Corporation expects that it will begin to incur interest costs associated with demand deposits. See Item 3. Quantitative and Qualitative Disclosures About Market Risk elsewhere in this report for information about the expected impact of this legislation on the Corporation’s sensitivity to interest rates. Further analysis of the components of the Corporation’s net interest margin is presented below.

The following table presents the changes in taxable-equivalent net interest income and identifies the changes due to differences in the average volume of earning assets and interest-bearing liabilities and the changes due to changes in the average interest rate on those assets and liabilities. The changes in net interest income due to changes in both average volume and average interest rate have been allocated to the average volume change or the average interest rate change in proportion to the absolute amounts of the change in each. The comparisons between the quarters include an additional change factor that shows the effect of the difference in the number of days in each period, as further discussed below.

Total change	$	4,455		$	2,871		$	10,749

Taxable-equivalent net interest income for the three months ended June 30, 2011 increased $4.5 million, or 2.9%, while taxable-equivalent net interest income for the six months ended June 30, 2011 increased $10.7 million, or 3.5%, compared to the same periods in 2010, respectively. The increases primarily resulted from increases in the average volume of interest-earning assets partly offset by decreases in the net interest margin. The average volume of interest-earning assets for the three and six months ended June 30, 2011 increased $1.3 billion and $1.2 billion compared to the same periods in 2010. The net interest margin decreased 23 basis points from 4.18% during the three months ended June 30, 2010 to 3.95% during the three months ended June 30, 2011 and decreased 19 basis points from 4.18% during the six months ended June 30, 2010 to 3.99% during the six months ended June 30, 2011. The decrease in the net interest margin was partly due to an increase in the relative proportion of interest-earning assets invested in lower-yielding interest-bearing deposits during 2011 compared to 2010 while the relative proportion of average interest-earning assets invested in higher-yielding loans decreased. The net interest margin was also negatively impacted by a decrease in the average yield on securities, as further discussed below.

Taxable-equivalent net interest income for the second quarter of 2011 increased $2.9 million, or 1.8%, from the first quarter of 2011. The increase primarily resulted from an increase in the average volume of interest-earning assets partly offset by a decrease in the net interest margin. Taxable-equivalent net interest income for the second quarter of 2011 was also impacted by an increase in the number of days compared to the first quarter of 2011. Taxable-equivalent net interest income for the first quarter of 2011 included 90 days compared to 91 days for the second quarter of 2011. The additional day added approximately $1.8 million to taxable-equivalent net interest income during the second quarter of 2011. Excluding the impact of the additional day during the second quarter of 2011 results in an effective increase in taxable-equivalent net interest income of approximately $1.1 million during the second quarter of 2011 which was primarily related to the aforementioned increase in average interest-earning assets partly offset by a decrease in the net interest margin. The average volume of interest-earning assets for the second quarter of 2011 increased $533.4 million compared to the first quarter of 2011. The net interest margin decreased 8 basis points from 4.03% in the first quarter of 2011 to 3.95% in the second quarter of 2011. The decrease in the net interest margin was partly due to an increase in the relative proportion of funds invested in lower yielding interest-bearing deposits during the second quarter.

The average yield on interest-earning assets decreased 27 basis points from 4.56% during the first six months of 2010 to 4.29% during the first six months of 2011 while the average cost of funds decreased 12 basis points from 0.58% during the first six months of 2010 to 0.46% during the first six months of 2011. The average yield on interest-earning assets is primarily impacted by changes in market interest rates as well as changes in the volume and relative mix of interest-earning assets. The average cost of funds is primarily impacted by changes in market interest rates as well as changes in the volume and relative mix of interest-bearing liabilities. As stated above, market interest rates have remained at historically low levels during the reported periods. The effect of lower average market interest rates on the average yield on average interest-earning assets was partly limited by the aforementioned interest rate swaps on variable-rate loans.

The average volume of loans during the six months ended June 30, 2011 decreased $125.1 million compared to the same period in 2010. Loans made up approximately 50.2% of average interest-earning assets during the first six months of 2011 compared to 55.1% during the first six months of 2010. The average yield on loans was 5.02% during the six months ended June 30, 2011 compared to 5.10% during the six months ended June 30, 2010. Loans generally have significantly higher yields compared to securities, interest-bearing deposits and federal funds sold and resell agreements and, as such, have a more positive effect on the net interest margin.

The average volume of securities increased $890.8 million during the six months ended June 30, 2011 compared to the same period in 2010. Securities made up approximately 36.6% of average interest-earning assets during the six months ended June 30, 2011 compared to 33.6% during the six months ended June 30, 2010. The average yield on securities was 4.76% during the six months ended June 30, 2011 compared to 5.16% during the six months ended June 30, 2010. The decrease in the average yield on securities was partly due to a decrease in the yield on taxable securities as proceeds from principal repayments were reinvested at lower market rates. The decrease in the average yield on securities was also partly related to a decrease in the relative proportion of higher-yielding, tax-exempt municipal securities during the first six months of 2011 compared to the prior period. The relative proportion of higher-yielding, tax-exempt municipal securities totaled 36.5% of average securities during the first six months of 2011 compared to 37.7% during the first six months of 2010. The average yield on taxable securities was 3.47% during the first six months of 2011 compared to 4.03% during the first six months of 2010, while the average taxable-equivalent yield on tax-exempt securities was 6.98% during the first six months of 2011 compared to 7.04% during the first six months of 2010.

Average federal funds sold, resell agreements and interest-bearing deposits during the six months ended June 30, 2011 increased $436.7 million compared to the same period in 2010. Federal funds sold, resell agreements and interest-bearing deposits made up approximately 13.2% of average interest-earning assets during the six months ended June 30, 2011 compared to 11.3% during the same period in 2010. The combined average yield on federal funds sold, resell agreements and interest-bearing deposits was 0.25% during the six months ended June 30, 2011 compared to 0.22% during the same period during 2010. The increases in average federal funds sold, resell agreements and interest-bearing deposits compared to the comparable periods in 2010 was primarily due to growth in average deposits.

Average deposits increased $1.0 billion during the first six months of 2011 compared to the same period in 2010. Average interest-bearing deposits for the first six months of 2011 increased $442 million compared to the same period in 2010. The ratio of average interest-bearing deposits to total average deposits was 63.5% during the first six months of 2011 compared to 64.9% during the same period in 2010. The average cost of deposits is primarily impacted by changes in market interest rates as well as changes in the volume and relative mix of interest-bearing deposits. The average cost of interest-bearing deposits and total deposits was 0.26% and 0.16% during the first six months of 2011 compared to 0.36% and 0.24% during the first six months of 2010. The decrease in the average cost of interest-bearing deposits during the comparable periods was primarily the result of decreases in interest rates offered on certain deposit products due to decreases in average market interest rates and decreases in renewal interest rates on maturing certificates of deposit given the current low interest rate environment. Additionally, during the first six month of 2011 compared to the same period in 2010, the relative proportion of higher-cost certificates of deposit to total average interest-bearing deposits decreased from 14.6% during the first six months of 2010 to 12.4% during the first six months of 2011.

The Corporation’s net interest spread, which represents the difference between the average rate earned on earning assets and the average rate paid on interest-bearing liabilities, was 3.83% during the first six months of 2011 and 3.98% the first six months of 2010. The net interest spread, as well as the net interest margin, will be impacted by future changes in short-term and long-term interest rate levels, as well as the impact from the competitive environment. A discussion of the effects of changing interest rates on net interest income is set forth in Item 3. Quantitative and Qualitative Disclosures About Market Risk included elsewhere in this report.

The Corporation’s hedging policies permit the use of various derivative financial instruments, including interest rate swaps, swaptions, caps and floors, to manage exposure to changes in interest rates. Details of the Corporation’s derivatives and hedging activities are set forth in Note 8 - Derivative Financial Instruments in the accompanying notes to consolidated financial statements included elsewhere in this report. Information regarding the impact of fluctuations in interest rates on the Corporation’s derivative financial instruments is set forth in Item 3. Quantitative and Qualitative Disclosures About Market Risk included elsewhere in this report.

Provision for Loan Losses

The provision for loan losses is determined by management as the amount to be added to the allowance for loan losses after net charge-offs have been deducted to bring the allowance to a level which, in management’s best estimate, is necessary to absorb probable losses within the existing loan portfolio. The provision for loan losses totaled $9.0 million and $18.4 million for the three and six months ended June 30, 2011 compared to $8.7 million and $22.2 million for the three and six months ended June 30, 2010. See the section captioned “Allowance for Loan Losses” elsewhere in this discussion for further analysis of the provision for loan losses.

Non-Interest Income

The components of non-interest income were as follows:


	Three Months Ended						Six Months Ended
	June 30,		March 31,		June 30,		June 30,		June 30,
	2011		2011		2010		2011		2010
Trust fees	$	18,976	$	18,220	$	17,037	$	37,196	$	34,000
Service charges on deposit accounts		23,619		23,368		24,925		46,987		49,734
Insurance commissions and fees		7,908		10,494		7,512		18,402		18,650
Other charges, commissions and fees		8,478		8,759		8,029		17,237		14,948
Net gain (loss) on securities transactions		—		5		1		5		6
Other		11,811		11,487		12,428		23,298		23,987

Total	$	70,792	$	72,333	$	69,932	$	143,125	$	141,325

Total non-interest income for the three and six months ended June 30, 2011 increased $860 thousand, or 1.2%, and $1.8 million, or 1.3%, compared to the same periods in 2010. Total non-interest income for the second quarter of 2011 decreased $1.5 million, or 2.1%, compared to the first quarter of 2011. Changes in the components of non-interest income are discussed below.

Trust Fees. Trust fee income for the three and six months ended June 30, 2011 increased $1.9 million, or 11.4%, and $3.2 million, or 9.4%, compared to the same periods in 2010. Investment fees are the most significant component of trust fees, making up approximately 74% and 73% of total trust fees for the first six months of 2011 and 2010, respectively. Investment and other custodial account fees are generally based on the market value of assets within a trust account. Volatility in the equity and bond markets impacts the market value of trust assets and the related investment fees.

The $1.9 million increase in trust fee income during the three months ended June 30, 2011 compared to the same period in 2010 was primarily the result of an increase in investment fees (up $1.8 million). The $3.2 million increase in trust fee income during the six months ended June 30, 2011 compared to the same period in 2010 was primarily the result of an increase in investment fees (up $2.5 million) and securities lending income (up $410 thousand). The increase in investment fees was primarily due to the general appreciation in the market values of assets in trust accounts on which these fees are generally based. Equity valuations during the respective periods of 2011 were higher on average compared to the same periods in 2010.

Trust fee income for the second quarter of 2011 increased $756 thousand, or 4.1%, from the first quarter of 2011. A seasonal increase in tax fees (up $693 thousand) as well as increases in oil and gas trust management fees (up $96 thousand) and in investment fees (up $71 thousand) were partly offset by a decrease in estate fees (down $177 thousand).

At June 30, 2011, trust assets, including both managed assets and custody assets, were primarily composed of fixed income securities (43.5% of trust assets), equity securities (42.3% of trust assets) and cash equivalents (9.0% of trust assets). The estimated fair value of trust assets was $25.3 billion (including managed assets of $10.2 billion and custody assets of $15.1 billion) at June 30, 2011, compared to $24.9 billion (including managed assets of $9.9 billion and custody assets of $15.0 billion) at December 31, 2010 and $22.2 billion (including managed assets of $9.6 billion and custody assets of $12.6 billion) at June 30, 2010.

Service Charges on Deposit Accounts. Service charges on deposit accounts for the three and six months ended June 30, 2011 decreased $1.3 million, or 5.2%, and $2.7 million, or 5.5%, compared to the same periods in 2010. The decreases were primarily due to decreases in overdraft/insufficient funds charges on both consumer and commercial accounts (down $1.5 million and $2.6 million during the three and six months ended June 30, 2011, respectively), decreases in service charges on commercial accounts (down $100 thousand and $883 thousand during the three and six months ended June 30, 2011, respectively), which was partly related to decreases in service volumes for billable services, and decreases in service charges on consumer accounts (down $105 thousand and $228 thousand during the three and six months ended June 30, 2011, respectively). The decrease in overdraft/insufficient funds charges on consumer accounts during 2011 was partly related to a new rule issued by the Federal Reserve that became effective in the third quarter of 2010, as further discussed below. The decreases in the aforementioned categories of service charges on deposit accounts were partly offset by an increases in point of sale income (up $429 thousand and $1.0 million during the three and six months ended June 30, 2011, respectively). The increase in point of sale income from PIN-based debit card transactions during the three and six months ended June 30, 2011 compared to the same periods in 2010 was related to an increase in the volume of transactions as well as a higher interchange pricing structure.

Service charges on deposit accounts for the second quarter of 2011 increased $251 thousand, or 1.1%, compared to the first quarter of 2011. The increase was due to increases in overdraft/insufficient funds charges on consumer accounts (up $281 thousand), point of sale income from PIN-based debit card transactions (up $194 thousand) and service charges on commercial accounts (up $190 thousand) partly offset by a decrease in overdraft/insufficient funds charges on commercial accounts (down $344 thousand).

Overdraft/insufficient funds charges totaled $8.5 million ($6.8 million consumer and $1.7 million commercial) during the second quarter of 2011 compared to $10.0 million ($7.9 million consumer and $2.1 million commercial) during the second quarter of 2010 and $8.6 million ($6.6 million consumer and $2.0 million commercial) during the first quarter of 2011. Overdraft/insufficient funds charges totaled $17.1 million ($13.4 million consumer and $3.7 million commercial) during the six months ended June 30, 2011 compared to $19.6 million ($15.3 million consumer and $4.3 million commercial) during the six months ended June 30, 2010. Overdraft/insufficient funds charges were partly impacted by changes in posting policies and a new rule issued by the Federal Reserve that became effective in the third quarter of 2010. The new rule prohibits financial institutions from charging consumers fees for paying overdrafts on automated teller machine and one-time debit card transactions, unless a consumer consents, or opts in, to the overdraft service for those types of transactions. Consumers must be provided a notice that explains the financial institution’s overdraft services, including the fees associated with the service, and the consumer’s choices.

Point of sale income from PIN-based debit card transactions totaled $3.7 million and $2.7 million during the six months ended June 30, 2011 and 2010, respectively. As discussed in the section captioned “Supervision and Regulation” included in Item 1. Business, of the 2010 Form 10-K, the Dodd-Frank Act amended the Electronic Fund Transfer Act (“EFTA”) to, among other things, give the Federal Reserve the authority to establish rules regarding interchange fees charged for electronic debit transactions by payment card issuers, such as Frost Bank. In June 2011, the Federal Reserve issued a final rule that, among other things, establishes standards for determining whether an interchange fee received or charged by an issuer with respect to an electronic debit transaction is reasonable and proportional to the cost incurred by the issuer with respect to the transaction. These new standards will take effect on October 1, 2011 and will apply to issuers, such as the Corporation, that, together with their affiliates, have assets of $10 billion or more. Under the rule, the maximum permissible interchange fee for an electronic debit transaction will be the sum of 21 cents per transaction and 5 basis points multiplied by the value of the transaction. The Federal Reserve also issued an interim final rule that allows for an upward adjustment of no more than 1 cent to an issuer’s debit card interchange fee if the issuer develops and implements policies and procedures reasonably designed to achieve the fraud-prevention standards set out in the interim final rule. The fraud-prevention adjustment is effective on October 1, 2011, concurrent with the debit card interchange fee limits. Based upon the new standards, the Corporation expects that revenues from debit card interchange transactions will likely be approximately half of current levels beginning October 1, 2011. Also see the discussion regarding income from Visa check card usage below under “Other Non-Interest Income.”

Insurance Commissions and Fees. Insurance commissions and fees for the three months ended June 30, 2011 increased $396 thousand, or 5.3%, compared to the same period in 2010. The increase is related to an increase in commission income (up $502 thousand) partly offset by a decrease in contingent commissions (down $105 thousand). Insurance commissions and fees for the six months ended June 30, 2011 decreased $248 thousand, or 1.3%, compared to the same period in 2010. The decrease is related to a decrease in contingent commissions (down $130 thousand) and commission income (down $117 thousand). The fluctuations in commission income were partly due to normal variation in the market demand for insurance products.

Insurance commissions and fees include contingent commissions totaling $551 thousand and $3.1 million during the three and six months ended June 30, 2011 and $656 thousand and $3.2 million during the three and six months ended June 30, 2010. Contingent commissions primarily consist of amounts received from various property and casualty insurance carriers related to the loss performance of insurance policies previously placed. Such commissions are seasonal in nature and are primarily received during the first quarter of each year. These property and casualty related commissions totaled $2.2 million and $2.4 million during the six months ended June 30, 2011 and 2010. Contingent commissions also include amounts received from various benefit plan insurance companies related to the volume of business generated and/or the subsequent retention of such business. These benefit plan related commissions totaled $531 thousand and $917 thousand during the three and six months ended June 30, 2011 and $571 thousand and $820 thousand during the three and six months ended June 30, 2010.

Insurance commissions and fees for the second quarter of 2011 decreased $2.6 million, or 24.6%, compared to the first quarter of 2011. The decrease was mostly due to the seasonal decrease in contingent commissions (down $2.2 million) received from various insurance carriers related to the performance of insurance policies previously placed. The decrease was also partly related to a decrease in commission income (down $577 thousand) compared to the first quarter of 2011 primarily due to normal variation in the timing of renewals and the market demand for insurance products.

Other Charges, Commissions and Fees. Other charges, commissions and fees for the three and six months ended June 30, 2011 increased $449 thousand, or 5.6%, and $2.3 million, or 15.3%, compared to the same periods in 2010. The increase during the three months ended June 30, 2011 was primarily related to increases in mutual fund management fees (up $400 thousand), loan processing fees (up $358 thousand), income related to sale of annuities (up $187 thousand) and unused balance fees on loan commitments (up $151 thousand). These increases were partly offset by a decrease in investment banking fees related to corporate advisory services (down $297 thousand) and a decrease in receivables factoring income (down $231 thousand). The increase in other charges, commissions and fees during the six months ended June 30, 2011 was primarily related to increases in mutual fund management fees (up $740 thousand), loan processing fees (up $504 thousand), income related to sale of annuities (up $434 thousand), investment banking fees related to corporate advisory services (up $396 thousand) and unused balance fees on loan commitments (up $344 thousand). These increases were partly offset by a decrease in receivables factoring income (down $408 thousand).

Other charges, commissions and fees for the second quarter of 2011 decreased $281 thousand, or 3.2%, compared to the first quarter of 2011. The decrease was primarily due to a decrease in investment banking fees related to corporate advisory services (down $760 thousand) partly offset by an increase in loan processing fees (up $296 thousand) as well as increases in various other categories of other charges, commissions and fees. Investment banking fees related to corporate advisory services are transaction based and can vary significantly from quarter to quarter.

Net Gain/Loss on Securities Transactions. During the six months ended June 30, 2011, the Corporation sold available-for-sale securities with an amortized cost totaling $5.5 billion and realized a net gain of $5.5 thousand on those sales. During the six months ended June 30, 2010, the Corporation sold available-for-sale securities with an amortized cost totaling $10.0 billion and realized a net gain of $6 thousand on those sales. These securities were primarily purchased during each respective year and subsequently sold primarily in connection with the Corporation’s tax planning strategies related to the Texas franchise tax. The gross proceeds from the sales of these securities outside of Texas are included in total revenues/receipts from all sources reported for Texas franchise tax purposes, which results in a reduction in the overall percentage of revenues/receipts apportioned to Texas and subjected to taxation under the Texas franchise tax.

Other Non-Interest Income. Other non-interest income for the three months ended June 30, 2011 decreased $617 thousand, or 5.0%, compared to the same period in 2010. Components of other non-interest income with significant decreases included income from securities trading and customer derivative activities (down $611 thousand), sundry income from various miscellaneous items (down $598 thousand) and lease rental income (down $212 thousand). Sundry income in 2010 included income from a settlement and an increased level of income from the collection of loan interest and other charges written-off in prior years. The decrease in income from securities trading and customer derivative activities was primarily related to decreases in customer interest rate swap transaction fees and securities trading gains. Components of other non-interest income with significant increases included income from check card activity (up $685 thousand) and gains on the sale of assets/foreclosed assets (up $545 thousand).

Other non-interest income for the six months ended June 30, 2011 decreased $689 thousand, or 2.9%, compared to the same periods in 2010. Components of other non-interest income with significant decreases included sundry income from various miscellaneous items (down $1.0 million), income from securities trading and customer derivative activities (down $851 thousand) and lease rental income (down $390 thousand). The decrease in income from securities trading and customer derivative activities was primarily related to decreases in customer interest rate swap transaction fees and securities trading gains partly offset by an increase in customer commodity swap transaction fees. Components of other non-interest income with significant increases included income from check card activity (up $1.3 million) and gains on the sale of assets/foreclosed assets (up $734 thousand).

Other non-interest income for the second quarter of 2011 increased $324 thousand, or 2.8%, compared to the first quarter of 2011. Contributing to the increase were increases in income from check card activity (up $489 thousand) and gains on the sale of assets/foreclosed assets (up $277 thousand) partly offset by a decrease in income from securities trading and customer derivative activities (down $242 thousand).

The Corporation had income from Visa check card usage totaling $11.5 million and $10.2 million during the six months ended June 30, 2011 and 2010. The Dodd-Frank Act amended the EFTA to, among other things, give the Federal Reserve the authority to establish rules regarding interchange fees charged for electronic debit transactions by payment card issuers, such as Frost Bank. As more fully discussed above relative to point of sale income from PIN-based debit card transactions under “Service Charges on Deposit Accounts,” in June 2011, the Federal Reserve issued new rules that will significantly impact the level of interchange fees that may be charged beginning October 1, 2011. At that time, under the new rules, the Corporation expects that revenues from Visa check card usage will likely be approximately half of current levels.

Total	$	136,797	$	140,061	$	134,654	$	276,858	$	269,248

Total non-interest expense for the three and six months ended June 30, 2011 increased $2.1 million, or 1.6%, and increased $7.6 million, or 2.8%, compared to the same periods in 2010. Total non-interest expense for the second quarter of 2011 decreased $3.3 million, or 2.3%, compared to the first quarter of 2011. Changes in the components of non-interest expense are discussed below.

Salaries and Wages. Salaries and wages for the three and six months ended June 30, 2011 increased $2.9 million, or 5.0%, and $5.1 million, or 4.3%, compared to the same periods in 2010. The increase during the three months ended June 30, 2011 was primarily related to normal annual merit and market increases and an increase in stock-based compensation expense. The increase during the six months ended June 30, 2011 was primarily related to increases in normal annual merit and market increases, incentive compensation and an increase in stock-based compensation expense. Salaries and wages expense for the second quarter of 2011 decreased $655 thousand, or 1.1%, compared to the first quarter of 2010. The decrease from the first quarter of 2011 was primarily related to an increase in cost deferrals related to lending activity as well as decreases in incentive compensation and stock-based compensation expense.

Employee Benefits. Employee benefits expense for the three and six months ended June 30, 2011 increased $375 thousand, or 3.0%, and $1.2 million, or 4.3%, compared to the same periods in 2010. The increase during the three months ended June 30, 2011 was primarily related to increases in expenses related to the Corporation’s 401(k) and profit sharing plans (up $443 thousand). The increase during the six months ended June 30, 2011 was primarily related to increases in expenses related to the Corporation’s 401(k) and profit sharing plans (up $911 thousand), payroll taxes (up $463 thousand) and medical insurance expense (up $150 thousand).

Employee benefits expense for the second quarter of 2011 decreased $2.3 million, or 14.8%, compared to the first quarter of 2011 primarily due to decreases in payroll taxes (down $1.7 million) and expenses related to the Corporation’s 401(k) and profit sharing plans (down $596 thousand). The Corporation generally experiences higher payroll taxes and 401(k) plan contribution matching expense during the first quarter of each year due to the increased payroll related to annual incentive compensation payments.

Combined expense related to the defined benefit retirement and restoration plans was not significant during the reported periods. The Corporation’s defined benefit retirement and restoration plans were frozen effective as of December 31, 2001 and were replaced by a profit sharing plan. Management believes these actions helped to reduce the volatility in retirement plan expense. However, the Corporation still has funding obligations related to the defined benefit and restoration plans and could recognize retirement expense related to these plans in future years, which would be dependent on the return earned on plan assets, the level of interest rates and employee turnover.

Net Occupancy. Net occupancy expense for the three and six months ended June 30, 2011 increased $186 thousand, or 1.6%, and $703 thousand, or 3.1%, compared to the same periods in 2010. The increase during the three months ended June 30, 2011 was primarily related to increases in building maintenance expense (up $202 thousand), repairs expense (up $160 thousand) and a decrease in parking garage income (down $154 thousand). Offsetting the increase in net occupancy expense related to the aforementioned items was an increase in rental income (up $120 thousand) and a decrease in lease expense (down $102 thousand). The increase during the six months ended June 30, 2011 was primarily related to increases in repairs expense (up $262 thousand), building maintenance expense (up $179 thousand), service contracts expense (up $162 thousand) and a decrease in parking garage income (down $175 thousand). Offsetting these items was a decrease in utilities expense (down $128 thousand). Net occupancy expense for the second quarter of 2011 increased $171 thousand, or 1.5%, compared to the first quarter of 2011. The increase was primarily related to increases in building maintenance expense (up $275 thousand) and utilities expense (up $109 thousand) as well as a decrease in parking garage income (down $153 thousand) partly offset by decreases in lease expense (down $176 thousand) and service contracts expense (down $125 thousand) and an increase in rental income (up $112 thousand).

Furniture and Equipment. Furniture and equipment expense for the three and six months ended June 30, 2011 increased $966 thousand, or 8.3%, and $1.8 million, or 7.6%, compared to the same periods in 2010. The increase during the three months ended June 30, 2011 was primarily related to increases in software maintenance (up $458 thousand), software amortization (up $406 thousand) and service contract expense (up $213 thousand) partly offset by a decrease in depreciation on furniture and fixtures (down $172 thousand). The increase during the six months ended June 30, 2011 was primarily related to increases in software maintenance (up $1.0 million) and software amortization (up $732 thousand) partly offset by a decrease in depreciation on furniture and fixtures (down $141 thousand). The increase in software amortization and maintenance was primarily related to new applications placed into service in 2010. Furniture and equipment expense for the second quarter of 2011 increased $347 thousand, or 2.8%, compared to the first quarter of 2011 primarily due to increases in service contract expense (up $289 thousand) and software amortization (up $172 thousand).

Deposit Insurance. Deposit insurance expense totaled $2.6 million and $7.4 million for the three and six months ended June 30, 2011 compared to $5.4 million and $10.9 million for the three and six months ended June 30, 2010. The decreases in deposit insurance expense in 2011 were primarily related to a change in the deposit insurance assessment base and a change in the method by which the assessment rate is determined for large financial institutions. Details of these changes are further discussed below. The decreases were also partly related to the Corporation opting out of the Transaction Account Guarantee component of the Temporary Liquidity Guarantee Program (“TLGP”) effective July 1, 2010. Deposit insurance expense decreased $2.2 million in the second quarter of 2011 compared to the first quarter of 2011. The decrease was primarily related to the aforementioned changes in the deposit insurance assessment base and the method by which the assessment rate is determined for large financial institutions.

In November 2009, the FDIC issued a rule that required all insured depository institutions, with limited exceptions, to prepay their estimated quarterly risk-based assessments for the fourth quarter of 2009 and for all of 2010, 2011 and 2012. As of June 30, 2011, $37.0 million in pre-paid deposit insurance is included in accrued interest receivable and other assets in the accompanying consolidated balance sheet.

In November 2010, the FDIC issued a final rule to implement provisions of the Dodd-Frank Act that provide for temporary unlimited coverage for non-interest-bearing transaction accounts. The separate coverage for non-interest-bearing transaction accounts became effective on December 31, 2010 and terminates on December 31, 2012.

On April 1, 2011, the deposit insurance assessment base changed from total domestic deposits to average total assets minus average tangible equity, pursuant to a rule issued by the FDIC as required by the Dodd-Frank Act. Additionally, the deposit insurance assessment system was revised to create a two scorecard system, one for most large institutions, including Frost Bank, that have more than $10 billion in assets and another for “highly complex” institutions that have over $50 billion in assets and are fully owned by a parent with over $500 billion in assets. Each scorecard has a performance score and a

loss-severity score that is combined to produce a total score, which is then translated into an initial assessment rate. In calculating these scores, the FDIC utilizes CAMELS ratings, certain financial measures to assess an institution’s ability to withstand asset-related stress and funding-related stress. The use of risk categories and long-term debt issuer ratings was eliminated. The FDIC has the ability to make discretionary adjustments to the total score, up or down, by a maximum of 15 points, based upon significant risk factors that are not adequately captured in the scorecard. The total score is constrained to be between 30 and 90 and translates to an initial base assessment rate on a non-linear, sharply-increasing scale.

For large institutions, including Frost Bank, the initial base assessment rate ranges from 5 to 35 basis points on an annualized basis (basis points representing cents per $100). After the effect of potential base-rate adjustments, the total base assessment rate could range from 2.5 to 45 basis points on an annualized basis. The potential adjustments to an institution’s initial base assessment rate include (i) a potential decrease of up to 5 basis points for certain long-term unsecured debt (“unsecured debt adjustment”) and (ii) (except for well-capitalized institutions with a CAMELS rating of 1 or 2) a potential increase of up to 10 basis points for brokered deposits in excess of 10% of domestic deposits (“brokered deposit adjustment”). As the deposit insurance fund (“DIF”) reserve ratio grows, the rate schedule will be adjusted downward. Additionally, the rule includes a new adjustment for depository institution debt whereby an institution will pay an additional premium equal to 50 basis points on every dollar (above 3% of an institution’s Tier 1 capital) of long-term, unsecured debt held that was issued by another insured depository institution (excluding debt guaranteed under the TLGP).

Intangible Amortization. Intangible amortization is primarily related to core deposit intangibles and, to a lesser extent, intangibles related to customer relationships and non-compete agreements. Intangible amortization for the three and six months ended June 30, 2011 decreased $192 thousand, or 14.8% and $405 thousand, or 15.4% compared to the same periods in 2010. The decreases in amortization expense are primarily the result of the completion of amortization of certain intangible assets and a reduction in the annual amortization rate of certain intangible assets as the Corporation uses an accelerated amortization approach which results in higher amortization rates during the earlier years of the useful lives of intangible assets. Intangible amortization expense during the second quarter of 2011 decreased $13 thousand, or 1.2%, compared to the first quarter of 2011. The decrease in intangible amortization during the second quarter 2011 was limited by the amortization of additional intangible assets acquired in the acquisition of Clark Benefit Group, an independent San Antonio based insurance agency. See Note 4 - Goodwill and Other Intangible Assets the accompanying notes to consolidated financial statements included elsewhere in this report.

Other Non-Interest Expense. Other non-interest expense for the three and six months ended June 30, 2011 increased $691 thousand, or 2.1%, and $2.8 million, or 4.4%, compared to the same periods in 2010. Components of other non-interest expense with significant increases during the three months ended June 30, 2011 included advertising/promotions expense (up $2.1 million), web-site maintenance expense (up $617 thousand), professional services expense (up $378 thousand), travel expense (up $325 thousand) and sub-advisor investment management fees related to Frost Investment Advisors, LLC, (up $322 thousand). The increase in advertising/promotions expense is primarily related to a new, expanded marketing campaign that began during the first quarter of 2011. The Corporation expects advertising/promotions expense throughout 2011 to be significantly higher than in 2010 as a result of this campaign. The increases in the aforementioned items were partly offset by decreases in sundry losses from various miscellaneous items (down $2.0 million), amortization of net deferred costs related to loan commitments (down $590 thousand), losses on the sale/write-down of foreclosed assets (down $556 thousand) and property taxes on foreclosed assets (down $554 thousand). Sundry expense from miscellaneous items during the second quarter of 2010 included several one-time charges for various write-offs, losses and refunds, which contributed to a higher level of expense in 2010.

Components of other non-interest expense with significant increases during the six months ended June 30, 2011 included advertising/promotions expense (up $2.9 million), losses on the sale/write-down of assets (up $1.2 million), web-site maintenance expense (up $1.0 million), sub-advisor investment management fees related to Frost Investment Advisors, LLC, (up $585 thousand), Visa check card expense (up $577 thousand) and travel expense (up $460 thousand). As mentioned above, the increase in advertising/promotions expense is primarily related to a new, expanded marketing campaign that began during the first quarter of 2011. The increase in losses on the sale/write-down of assets was primarily related to a $900 thousand write-down of a branch facility that is in the process of being sold. The increases in the aforementioned items were partly offset by decreases in losses on the sale/write-down of foreclosed assets (down $1.8 million), sundry losses from various miscellaneous items (down $1.4 million), amortization of net deferred costs related to loan commitments (down $706 thousand), property taxes on foreclosed assets (down $624 thousand) and Federal Reserve service charges (down $558 thousand).

Total other non-interest expense for the second quarter of 2011 increased $1.3 million, or 4.0%, compared to the first quarter of 2011. Significant components of the increase included increases in advertising/promotions expense (up $1.6 million), travel expense (up $525 thousand), professional services expense (up $514 thousand) and web-site maintenance expense (up $332 thousand). These increases were partly offset by decreases in amortization of net deferred costs related to loan commitments (down $732 thousand), sundry losses from various miscellaneous items (down $853 thousand) and losses on the sale/write-down of assets (down $631 thousand).

Banking

Net income for the three and six months ended June 30, 2011 increased $2.3 million, or 4.4%, and $5.4 million, or 5.3%, compared to the same periods in 2010. The increase during the three months ended June 30, 2011 was primarily the result of a $2.6 million increase in net interest income and a $2.4 million decrease in income tax expense partly offset by a $1.2 million decrease in non-interest income, a $1.0 million increase in non-interest expense and a $335 thousand increase in the provision for loan losses. The increase during the six months ended June 30, 2011 was primarily the result of a $6.6 million increase in net interest income, a $3.8 million decrease in the provision for loan losses and a $2.9 million decrease in income tax expense partly offset by a $5.4 million increase in non-interest expense and a $2.5 million decrease in non-interest income.

Net interest income for the three and six months ended June 30, 2011 increased $2.6 million, or 1.8%, and $6.6 million, or 2.3%, compared to the same periods in 2010. The increases primarily resulted from increases in the average volume of interest-earning assets partly offset by decreases in the net interest margin. See the analysis of net interest income included in the section captioned “Net Interest Income” included elsewhere in this discussion.

The provision for loan losses for the three and six months ended June 30, 2011 totaled $9.0 million and $18.4 million compared to $8.7 million and $22.2 million for the same periods in 2010. See the analysis of the provision for loan losses included in the section captioned “Allowance for Loan Losses” included elsewhere in this discussion.

Non-interest income for the three and six months ended June 30, 2011 decreased $1.2 million, or 2.6%, and $2.5 million, or 2.5%, compared to the same periods in 2010. The decrease during the three months ended June 30, 2011 was primarily due to decreases in service charges on deposit accounts and other non-interest income partly offset by an increase in insurance commissions and fees. The decrease during the six months ended June 30, 2011 was primarily due to decreases in service charges on deposit accounts, other non-interest income and insurance commissions and fees partly offset by an increase in other charges, commissions and fees. See the analysis of these categories of non-interest income included in the section captioned “Non-Interest Income” included elsewhere in this discussion.

Non-interest expense for the three months and six ended June 30, 2011 increased $1.0 million, or 0.9%, and increased $5.4 million, or 2.4%, compared to the same periods in 2010. The increases were primarily related to increases in salaries and wages, furniture and equipment expense, employee benefits, other non-interest expense and net occupancy partly offset by decreases in deposit insurance expense and intangible amortization. The increases in salaries and wages were primarily related to normal annual merit increases and an increases in incentive compensation and stock-based compensation. The increase in furniture and equipment expense was due to increases in software maintenance and software amortization. The increases in employee benefits expense were primarily related to increases in expenses related to the Corporation’s 401(k) and profit sharing plans and an increase in payroll taxes. The increases in other non-interest expense were partly related to increases in advertising/promotions expense, among other things. The decrease in deposit insurance was primarily related to a change in the deposit insurance assessment base and a change in the method by which the assessment rate is determined for large financial institutions. The decrease was also partly related to the Corporation opting out of the Transaction Account Guarantee component of the Temporary Liquidity Guarantee Program effective July 1, 2010. See the analysis of these items included in the section captioned “Non-Interest Expense” included elsewhere in this discussion.

Frost Insurance Agency, which is included in the Banking operating segment, had gross commission revenues of $7.9 million and $18.5 million during the three and six months ended June 30, 2011 and $7.5 million and $18.8 million during the three and six months ended June 30, 2010. Insurance commission revenues increased $396 thousand, or 5.3%,

during the three months ended June 30, 2011 and decreased $248 thousand, or 1.3%, during the six months ended June 30, 2011, compared to the same periods in 2010. See the analysis of insurance commissions and fees included in the section captioned “Non-Interest Income” included elsewhere in this discussion.

Financial Management Group (FMG)

Net income for the three and six months ended June 30, 2011 increased $679 thousand, or 30.1%, and $1.0 million, or 29.2%, compared to the same periods in 2010. The increase during the three months ended June 30, 2011 was primarily due to a $2.3 million increase non-interest income partly offset by a $1.0 million increase in non-interest expense, a $365 thousand increase in income tax expense and a $206 thousand decrease in net interest income. The increase during the six months ended June 30, 2011 was primarily due to a $4.3 million increase non-interest income partly offset by a $2.5 million increase in non-interest expense, a $566 thousand increase in income tax expense and a $180 thousand decrease in net interest income.

Net interest income for the three and six months ended June 30, 2011 decreased $206 thousand, or 12.5%, and $180 thousand, or 6.0%, compared to the same periods in 2010. The decrease in net interest income was due to a decrease in the funds transfer price received for funds provided to the Corporation.

Non-interest income for the three and six months ended June 30, 2011 increased $2.3 million, or 10.5%, and $4.3 million, or 10.0%, compared to the same periods in 2010. The increase during the three months ended June 30, 2011 was primarily due to increases in trust fees (up $2.0 million) and other charges, commissions and fees (up $434 thousand) partly offset by a decrease in other non-interest income (down $138 thousand). The increase during the six months ended June 30, 2011 was primarily due to increases in trust fees (up $3.3 million) and other charges, commissions and fees (up $1.2 million) partly offset by a decrease in other non-interest income (down $211 thousand).

Trust fee income is the most significant income component for FMG. Investment fees are the most significant component of trust fees, making up approximately 74% and 73% of total trust fees for the first six months of 2011 and 2010, respectively. Investment and other custodial account fees are generally based on the market value of assets within a trust account. Volatility in the equity and bond markets impacts the market value of trust assets and the related investment fees. The increase in trust fee income during the three months ended June 30, 2011 compared to the same period in 2010 was primarily the result of an increase in investment fees. The increase in trust fee income during the six months ended June 30, 2011 compared to the same period in 2010 was primarily the result of an increase in investment fees and securities lending income. See the analysis of trust fees included in the section captioned “Non-Interest Income” included elsewhere in this discussion.

The increases in other charges, commissions and fees during the three and six months ended June 30, 2011 compared to the same periods in 2010 were primarily due to increases in mutual fund management fees and income related to the sale of annuities.

Non-interest expense for the three and six months ended June 30, 2011 increased $1.0 million, or 5.2%, and $2.5 million, or 6.2%, compared to the same periods in 2010. The increases were primarily due to increases in salaries and wages (up $737 thousand during the three months ended June 30, 2011 and $766 thousand during the six months ended June 30, 2011), and other non-interest expense (up $303 thousand during the three months ended June 30, 2011 and $1.8 million during the six months ended June 30, 2011). The increase in salaries and wages was primarily related to normal annual merit and market increases and, to a lesser extent, increases in stock-based compensation. The increases in other non-interest expense were partly related to increases in sub-advisor investment management fees related to Frost Investment Advisors, LLC, and increases in various overhead cost allocations, among other things, partly offset by decreases in sundry losses from various miscellaneous items.

Non-Banks

The net loss for the Non-Banks operating segment increased $242 thousand and decreased $411 thousand for the three and six months ended June 30, 2011, respectively, compared to the same periods in 2010. The increase during the three months ended June 30, 2011 was primarily due to a $169 thousand decrease in non-interest income, an $82 thousand increase in non-interest expense and an $82 thousand increase in income tax expense partly offset by a $91 thousand decrease in net interest expense. The decrease during the six months ended June 30, 2011 was primarily due to a $252 thousand decrease in non-interest expense and a $193 thousand decrease in net interest expense.

Income Taxes

The Corporation recognized income tax expense of $13.7 million and $26.3 million, for an effective tax rate of 19.7% and 19.6% for the three and six months ended June 30, 2011 compared to $15.6 million and $28.6 million, for an effective tax rate of 22.8% and 22.1% for the three and six months ended June 30, 2010. The effective income tax rates differed from the U.S. statutory rate of 35% during the comparable periods primarily due to the effect of tax-exempt income from loans, securities and life insurance policies. The decrease in the effective tax rate during 2011 was primarily the result of an increase in holdings of tax-exempt municipal securities.

Average Balance Sheet

Average assets totaled $17.9 billion for the six months ended June 30, 2011 representing an increase of $1.2 billion, or 7.3 %, compared to average assets for the same period in 2010. The increase was primarily reflected in earning assets, which increased $1.2 billion, or 8.1%, during the first six months of 2011 compared to the same period in 2010. The increase in earning assets was primarily due to a $890.8 million increase in average securities and a $436.7 million increase in average interest-bearing deposits and federal funds sold and resale agreements partly offset by a $125.1 million decrease in average loans. The growth in average interest-earning assets was primarily funded by an increase in deposits. Total deposits averaged $14.7 billion for the first six months of 2011, increasing $1.0 billion, or 7.3%, compared to the same period in 2010. Average interest-bearing accounts totaled 63.5% and 64.9% of average total deposits during the first six months of 2011 and 2010, respectively.

Total loans	$	8,068,212			100.0	%	$	8,025,080		$	8,117,020		$	8,065,679

Loans decreased $48.8 million, or 0.6%, compared to December 31, 2010. The majority of the Corporation’s loan portfolio is comprised of commercial and industrial loans and real estate loans. Commercial and industrial loans made up 47.6% and 46.7% of total loans at June 30, 2011 and December 31, 2010, respectively while real estate loans made up 48.7% and 49.3% of total loans, respectively, at those dates. Real estate loans include both commercial and consumer balances.

Commercial and industrial loans increased $53.5 million, or 1.4%, during the first six months of 2011. The Corporation’s commercial and industrial loans are a diverse group of loans to small, medium and large businesses. The purpose of these loans varies from supporting seasonal working capital needs to term financing of equipment. While some short-term loans may be made on an unsecured basis, most are secured by the assets being financed with collateral margins that are consistent with the Corporation’s loan policy guidelines. The commercial and industrial loan portfolio also includes the commercial lease and asset-based lending portfolios as well as purchased shared national credits (“SNC”s) which are discussed in more detail below.

Purchased shared national credits are participations purchased from upstream financial organizations and tend to be larger in size than the Corporation’s originated portfolio. The Corporation’s purchased SNC portfolio totaled $483.6 million at June 30, 2011, increasing $23.6 million, or 5.1%, from $460.0 million at December 31, 2010. At June 30, 2011, 66.1% of outstanding purchased SNCs was related to the energy industry. The remaining purchased SNCs were diversified throughout various other industries, with no other single industry exceeding 10% of the total purchased SNC portfolio. Additionally, almost all of the outstanding balance of purchased SNCs was included in the commercial and industrial portfolio, with the remainder included in the real estate categories. SNC participations are originated in the normal course of business to meet the needs of the Corporation’s customers. As a matter of policy, the Corporation generally only participates in SNCs for companies headquartered in or which have significant operations within the Corporation’s market areas. In addition, the Corporation must have direct access to the company’s management, an existing banking relationship or the expectation of broadening the relationship with other banking products and services within the following 12 to 24 months. SNCs are reviewed at least quarterly for credit quality and business development successes.

Real estate loans decreased $70.9 million, or 1.8%, during the first six months of 2011. Real estate loans include both commercial and consumer balances. Commercial real estate loans totaled $3.2 billion at June 30, 2011 and represented 80.3% of total real estate loans. The majority of this portfolio consists of commercial real estate mortgages, which includes both permanent and intermediate term loans. The Corporation’s primary focus for its commercial real estate portfolio has been growth in loans secured by owner-occupied properties. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Consequently, these loans must undergo the analysis and underwriting process of a commercial and industrial loan, as well as that of a real estate loan.

The consumer loan portfolio, including all consumer real estate, decreased $46.3 million, or 4.1%, from December 31, 2010. As the following table illustrates, the consumer loan portfolio has two distinct segments, including consumer real estate and consumer installment.


	June 30, 2011		March 31, 2011		December 31, 2010		June 30, 2010
Consumer real estate:
Home equity loans	$	276,869	$	274,952	$	275,806	$	274,129
Home equity lines of credit		189,356		187,573		186,465		175,753
1-4 family residential mortgages		49,849		53,587		57,877		63,220

Other		239,043		244,752		254,551		270,677

Total consumer real estate		773,069		784,368		798,264		811,954
Consumer installment		298,327		307,812		319,384		340,719

Total consumer loans	$	1,071,396	$	1,092,180	$	1,117,648	$	1,152,673

Consumer real estate loans, decreased $25.2 million, or 3.2%, from December 31, 2010. Combined, home equity loans and lines of credit made up 60.3% and 57.9% of the consumer real estate loan total at June 30, 2011 and December 31, 2010, respectively. The Corporation offers home equity loans up to 80% of the estimated value of the personal residence of the borrower, less the value of existing mortgages and home improvement loans. In general, the Corporation no longer originates 1-4 family mortgage loans, however, from time to time, the Corporation may invest in such loans to meet the needs of its customers.

The consumer installment loan portfolio primarily consists of automobile loans, unsecured revolving credit products, personal loans secured by cash and cash equivalents, and other similar types of credit facilities.

Non-Performing Assets

Non-performing assets and accruing past due loans are presented in the table below. The Corporation did not have any restructured loans as of the dates presented.

Total accruing past due loans		0.72	%		1.11	%		1.01	%		1.24	%

Non-performing assets include non-accrual loans and foreclosed assets. Non-performing assets at June 30, 2011 decreased $3.6 million from December 31, 2010. In general, the level of non-performing assets during the comparable periods is reflective of weaker economic conditions which began in the latter part of 2008, although the Corporation has experienced decreases in the levels of classified assets in recent quarters. Non-accrual commercial loans included four credit relationships in excess of $5 million totaling $38.5 million at June 30, 2011, including one relationship totaling $15.8 million placed on non-accrual status during the second quarter of 2011, and three credit relationships in excess of $5 million totaling $25.8 million at December 31, 2010. Non-accrual real estate loans primarily consist of land development, 1-4 family residential construction credit relationships and loans secured by office buildings and religious facilities. Generally, loans are placed on non-accrual status if principal or interest payments become 90 days past due and/or management deems the collectability of the principal and/or interest to be in question, as well as when required by regulatory requirements. Once interest accruals are discontinued, accrued but uncollected interest is charged to current year operations. Subsequent receipts on non-accrual loans are recorded as a reduction of principal, and interest income is recorded only after principal recovery is reasonably assured.

Foreclosed assets represent property acquired as the result of borrower defaults on loans. Foreclosed assets are recorded at estimated fair value, less estimated selling costs, at the time of foreclosure. Write-downs occurring at foreclosure are charged against the allowance for loan losses. Subsequent to foreclosure, the fair value of property held is monitored/evaluated by a third-party service and reviewed with management on a quarterly basis. Write-downs are provided for subsequent declines in value and are included in other non-interest expense along with other expenses related to maintaining the properties. During 2011 and 2010, foreclosed assets, particularly among certain classes of property (primarily land), experienced significant deterioration in fair values as a result of the prevailing weaker economic conditions. Write-downs of foreclosed assets totaled $803 thousand and $1.1 million, during the six months ended June 30, 2011 and 2010, respectively. During the six months ended June 30, 2011, the Corporation recognized write-downs on 13 different properties/relationships with the average write-down totaling $62 thousand and the largest individual write-down totaling $215 thousand. The weighted-average percentage write-down was 26.2%. The weighted-average number of days these properties were held as foreclosed assets prior to write-down was 221 days. During the six months ended June 30, 2010, the Corporation recognized write-downs on 26 different properties/relationships with the average write-down totaling $41 thousand and the largest individual write-down totaling $220 thousand. The weighted-average percentage write-down was 34.6%. The weighted-average number of days these properties were held as foreclosed assets prior to write-down was 451 days. There were no significant concentrations of any properties, to which the aforementioned write-downs relate, in any single geographic region.

Potential problem loans consist of loans that are performing in accordance with contractual terms but for which management has concerns about the ability of an obligor to continue to comply with repayment terms because of the obligor’s potential operating or financial difficulties. Management monitors these loans closely and reviews their performance on a regular basis. At June 30, 2011 and December 31, 2010, the Corporation had $39.8 million and $33.8 million in loans of this type which are not included in either of the non-accrual or 90 days past due loan categories. At June 30, 2011, potential problem loans consisted of five credit relationships. Of the total outstanding balance at June 30, 2011, 67.9% related to a customer in the business of road construction, 15.7% related to two customers in manufacturing and 13.0% related to a customer that operates a hotel. Weakness in these companies’ operating performance has caused the Corporation to heighten the attention given to these credits.

Allowance for Loan Losses

The allowance for loan losses is a reserve established through a provision for loan losses charged to expense, which represents management’s best estimate of probable losses that have been incurred within the existing portfolio of loans. The allowance, in the judgment of management, is necessary to reserve for estimated loan losses and risks inherent in the loan portfolio. The Corporation’s allowance for loan loss methodology includes allowance allocations calculated in accordance with ASC Topic 310, “Receivables” and allowance allocations calculated in accordance with ASC Topic 450, “Contingencies.” Accordingly, the methodology is based on historical loss experience by type of credit and internal risk grade, specific homogeneous risk pools and specific loss allocations, with adjustments for current events and conditions. The Corporation’s process for determining the appropriate level of the allowance for loan losses is designed to account for credit deterioration as it occurs. The provision for loan losses reflects loan quality trends, including the levels of and trends related to non-accrual loans, past due loans, potential problem loans, classified and criticized loans and net charge-offs or recoveries, among other factors. The provision for loan losses also reflects the totality of actions taken on all loans for a particular period. In other words, the amount of the provision reflects not only the necessary increases in the allowance for loan losses related to newly identified criticized loans, but it also reflects actions taken related to other loans including, among other things, any necessary increases or decreases in required allowances for specific loans or loan pools. See Note 3 - Loans in the accompanying notes to consolidated financial statements included elsewhere in this report for further details regarding the Corporation’s methodology for estimating the appropriate level of the allowance for loan losses.

The table below provides, as of the dates indicated, an allocation of the allowance for loan losses by loan type; however, allocation of a portion of the allowance to one category of loans does not preclude its availability to absorb losses in other categories:


	June 30, 2011		December 31, 2010		June 30, 2010
Commercial and industrial	$	56,566	$	57,789	$	65,293
Commercial real estate		20,901		28,534		31,229
Consumer real estate		3,683		3,223		2,467
Consumer and other		12,611		11,974		18,763
Unallocated		28,980		24,796		7,690

Total	$	122,741	$	126,316	$	125,442

As of June 30, 2011, the reserve allocated to commercial and industrial loans decreased $1.2 million compared to December 31, 2010 and $8.7 million compared to June 30, 2010. The decreases were primarily related to decreases in the level of classified loans. Classified commercial and industrial loans (loans having a risk grade of 11, 12 or 13) totaled $194.2 million at June 30, 2011 compared to $198.3 million at December 31, 2010 and $238.6 million at June 30, 2010. The decreases were also due, in part, to a decrease in the historical loss allocation factor applied to non-classified commercial and industrial loans. The base historical loss allocation for each category of loans is the product of the volume of loans within each level of risk classification and the historical loss allocation factor for that particular level of risk classification, adjusted, as necessary to reflect the impact of current conditions. The base historical loss allocation is then adjusted upwards utilizing an environmental adjustment factor that is based upon a more qualitative analysis of risk. See Note 3 - Loans in the accompanying notes to consolidated financial statements for information regarding the various risks that may be considered in the determination of the environmental adjustment factor. Prior to the first quarter of 2011, the base historical loss allocation factors for non-classified loans determined based upon actual historical loss experience were adjusted upwards given the continued higher levels of charge-offs relative to historical average and the prevailing uncertain economic conditions. During the first quarter of 2011, the amounts of these upward adjustments were partly reduced in light of the decreasing trend in classified loans and an improvement in the outlook related to credit quality. The impact of these reductions was partly offset by the effect of an increase in the environmental adjustment factor. The environmental adjustment factor resulted in additional general valuation allowances for commercial and industrial loans totaling $5.7 million at June 30, 2011, $4.4 million at December 31, 2010 and $3.9 million at June 30, 2010. Specific allocations of the allowance for loan losses related to commercial and industrial loans totaled $17.0 million at June 30, 2011 compared to $9.1 million at December 31, 2010 and $16.7 million at June 30, 2010.

As of June 30, 2011, the reserve allocated to commercial real estate loans decreased $7.6 million compared to December 31, 2010 and $10.3 million compared to June 30, 2010. The decreases were primarily related to decreases in the level of classified loans. Classified commercial real estate loans totaled $172.1 million at June 30, 2011 compared to $213.6 million at December 31, 2010 and $225.0 million at June 30, 2010. The decrease was also due, in part, to a decrease in the historical loss allocation factor applied to non-classified commercial real estate loans, as discussed above with regards to commercial and industrial loans, offset by the effect of an increase in the environmental adjustment factor. The environmental adjustment factor resulted in additional general valuation allowances for commercial real estate loans totaling $3.8 million at June 30, 2011, $3.0 million at December 31, 2010 and $3.3 million at June 30, 2010. Specific allocations of the allowance for loan losses related to commercial real estate loans totaled $1.3 million at June 30, 2011 compared to $4.1 million at December 31, 2010 and $4.3 million at June 30, 2010.

The reserve allocated to consumer real estate loans did not significantly fluctuate at June 30, 2011 compared to December 31, 2010 and June 30, 2010, while the reserve allocated to consumer and other loans at June 30, 2011 increased $637 thousand compared to December 31, 2010 and decreased $6.2 million compared to June 30, 2010. The increase in the reserve allocated to consumer and other loans at June 30, 2011 compared to December 31, 2010 was primarily related to an increase in the historical loss allocation factor and an increase in the environmental adjustment factor, partly offset by the effect of a decrease in the volume of loans. The decrease in the reserve allocated to consumer and other loans at June 30, 2011 compared to June 30, 2010 was primarily related to a decrease in the volume of loans, partly offset by the effect of an increase in the historical loss allocation factor and an increase in the environmental adjustment factor.

The unallocated portion of the allowance for loan losses represents general valuation allowances that are not allocated to specific loan portfolio segments. See Note 3 - Loans in the accompanying notes to consolidated financial statements for information regarding the components of the unallocated portion of the allowance. The unallocated portion of the allowance for loan losses at June 30, 2011 increased $4.2 million compared to December 31, 2010 and increased $21.3 million compared to June 30, 2010. These fluctuations were primarily due to increases in the allocation for general macroeconomic risk which totaled $19.7 million at June 30, 2011 compared to $18.0 million at December 31, 2010 and $605 thousand at June 30, 2010. As of June 30, 2010, the allocation for general macroeconomic risk was at a reduced level in light of several factors including (i) a stabilization of the weighted-average portfolio risk grade trend, in part due to higher resolutions and more downgrades migrating from risk grade 10 rather than risk grade 9 or better, (ii) management’s belief that the level of classified loans had reached its peak and that there was less uncertainty about the Corporation’s loan portfolio, (iii) a decrease in the rate of quarterly charge-offs, (iv) decreased volatility in risk-grade movements coupled with the expectation of less volatility for the later part of 2010 and (v) favorable trends in certain components of the Texas Leading index, an economic indicator which management believes portends credit quality direction. By December 31, 2010, the allocation for general macroeconomic risk had increased $17.4 million from June 30, 2010 as management believed that the improving trends seen in certain components of the Texas Leading Index, as well as in the national economy as a whole, were primarily driven by government stimulus programs, the extension of tax cuts and the monetary policy of the Federal Reserve with regards to quantitative easing. Such measures were expected to act as a catalyst for long-term growth; however, while short-term improvements were seen, management believes that these measure did not lead to private-sector employment growth and increased consumer spending levels as they were expected. Accordingly, the $17.4 million increase in the allocation for general macroeconomic risk during the second half of 2010 and the further $1.7 million during the six months ended June 30, 2011 compared to December 31, 2010 were reflective of continued economic uncertainty resulting from weakness in certain business sectors (including contractors, builders, commercial real estate, manufacturing and healthcare), high unemployment and relatively low consumer spending activity. The Corporation primarily monitors communications and statistical data from the Federal Reserve and other agencies of the U.S. government in assessing the status of these factors.

Ratio of annualized net charge-offs to average total loans		0.52			0.57			0.42			0.55			0.54

The provision for loan losses increased $335 thousand, or 3.9%, during the three months ended June 30, 2011 and decreased $3.8 million, or 17.0%, during the six months ended June 30, 2011 compared to the same periods in 2010. The provision for loan losses decreased $465 thousand, or 4.9%, during the second quarter of 2011 compared to the first quarter of 2011. The level of the provision for loan losses during 2011 is reflective of the decreasing trend in classified loans. Net charge-offs during the three months ended June 30, 2011 increased $2.0 million while net charge-offs during the six months ended June 30, 2011 did not significantly fluctuate, compared in each case, to the same periods in 2010. Net charge-offs for the second quarter of 2011 decreased $880 thousand compared to the first quarter of 2011. The ratio of the allowance for loan losses to total loans decreased 4 basis point from 1.56% at December 31, 2010 to 1.52% at June 30, 2011. Management believes the recorded amount of the allowance for loan losses is appropriate based upon management’s best estimate of probable losses that have been incurred within the existing portfolio of loans. Should any of the factors considered by management in evaluating the appropriate level of the allowance for loan losses change, the Corporation’s estimate of probable loan losses could also change, which could affect the level of future provisions for loan losses.

Capital and Liquidity

Capital. Shareholders’ equity totaled $2.2 billion at June 30, 2011, $2.1 billion at December 31, 2010 and $2.0 billion at June 30, 2010. In addition to net income of $107.6 million, other changes in shareholders’ equity during the first six months of 2011 included $55.8 million of dividends paid, other comprehensive income, net of tax, of $48.3 million, $7.2 million in proceeds from stock option exercises and the related tax benefits of $278 thousand and $7.6 million related to stock-based compensation. Additionally, the Corporation issued $1.4 million in newly issued common stock directly to the Corporation’s 401(k) plan in connection with matching contributions.

The accumulated other comprehensive income/loss component of shareholders’ equity totaled a net, after-tax, unrealized gain of $202.6 million at June 30, 2011 compared to a net, after-tax, unrealized gain of $154.3 million at December 31, 2010. The increase was primarily due to a $59.1 million net after-tax increase in the net unrealized gain on securities available for sale partly offset by a $11.8 million net after-tax decrease in the accumulated net gain on effective cash flow hedges. Under regulatory requirements, amounts reported as accumulated other comprehensive income/loss related to securities available for sale, effective cash flow hedges and defined benefit post-retirement benefit plans do not increase or reduce regulatory capital

and are not included in the calculation of risk-based capital and leverage ratios. Regulatory agencies for banks and bank holding companies utilize capital guidelines designed to measure Tier 1 and total capital and take into consideration the risk inherent in both on-balance sheet and off-balance sheet items. See Note 7 - Regulatory Matters in the accompanying notes to consolidated financial statements included elsewhere in this report.

The Corporation paid quarterly dividends of $0.45 and $0.46 per common share during the first and second quarters of 2011 and quarterly dividends of $0.43 and $0.45 per common share during the first and second quarters of 2010. This equates to a dividend payout ratio of 53.1% and 50.7% during the first and second quarters of 2011 and 54.2% and 51.6% during the first and second quarters of 2010.

From time to time, the Corporation’s board of directors has authorized stock repurchase plans. Stock repurchase plans allow the Corporation to proactively manage its capital position and return excess capital to shareholders. Shares purchased under such plans also provide the Corporation with shares of common stock necessary to satisfy obligations related to stock compensation awards. No shares were repurchased under stock repurchase plans during any of the reported periods. See Part II, Item 2 - Unregistered Sales of Equity Securities and Use of Proceeds, included elsewhere in this report, for details of stock repurchases during the quarter.

Liquidity. Liquidity measures the ability to meet current and future cash flow needs as they become due. The liquidity of a financial institution reflects its ability to meet loan requests, to accommodate possible outflows in deposits and to take advantage of interest rate market opportunities. The ability of a financial institution to meet its current financial obligations is a function of its balance sheet structure, its ability to liquidate assets, and its access to alternative sources of funds. The Corporation seeks to ensure its funding needs are met by maintaining a level of liquid funds through asset/liability management.

Asset liquidity is provided by liquid assets which are readily marketable or pledgeable or which will mature in the near future. Liquid assets include cash, interest-bearing deposits in banks, securities available for sale, maturities and cash flow from securities held to maturity, and federal funds sold and resell agreements.

Liability liquidity is provided by access to funding sources which include core deposits and correspondent banks in the Corporation’s natural trade area that maintain accounts with and sell federal funds to Frost Bank, as well as federal funds purchased and repurchase agreements from upstream banks and deposits obtained through financial intermediaries.

Since Cullen/Frost is a holding company and does not conduct operations, its primary sources of liquidity are dividends upstreamed from Frost Bank and borrowings from outside sources. Banking regulations may limit the amount of dividends that may be paid by Frost Bank. See Note 7 - Regulatory Matters in the accompanying notes to consolidated financial statements included elsewhere in this report regarding such dividends. At June 30, 2011, Cullen/Frost had liquid assets, including cash and resell agreements, totaling $172.2 million, which included $10.0 million in cash collateral on deposit with other financial institution counterparties to interest rate swap transactions.

The liquidity position of the Corporation is continuously monitored and adjustments are made to the balance between sources and uses of funds as deemed appropriate. Management is not aware of any events that are reasonably likely to have a material adverse effect on the Corporation’s liquidity, capital resources or operations. In addition, management is not aware of any regulatory recommendations regarding liquidity, which if implemented, would have a material adverse effect on the Corporation.

The Corporation’s operating and strategic objectives include expansion, diversification within its markets, growth of its fee-based income, and growth internally and through acquisitions of financial institutions, branches and financial services businesses. The Corporation generally seeks merger or acquisition partners that are culturally similar and have experienced management and possess either significant market presence or have potential for improved profitability through financial management, economies of scale and expanded services. The Corporation regularly evaluates merger and acquisition opportunities and conducts due diligence activities related to possible transactions with other financial institutions and financial services companies. As a result, merger or acquisition discussions and, in some cases, negotiations may take place and future mergers or acquisitions involving cash, debt or equity securities may occur. Acquisitions typically involve the payment of a premium over book and market values, and, therefore, some dilution of the Corporation’s tangible book value and net income per common share may occur in connection with any future transaction.

Item 3.

Quantitative and Qualitative Disclosures About Market Risk

The disclosures set forth in this item are qualified by the section captioned “Forward-Looking Statements and Factors that Could Affect Future Results” included in Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations of this report and other cautionary statements set forth elsewhere in this report.

Refer to the discussion of market risks included in Item 7A. Quantitative and Qualitative Disclosures About Market Risk in the 2010 Form 10-K. There has been no significant change in the types of market risks faced by the Corporation since December 31, 2010.

The Corporation utilizes an earnings simulation model as the primary quantitative tool in measuring the amount of interest rate risk associated with changing market rates. The model quantifies the effects of various interest rate scenarios on projected net interest income and net income over the next 12 months. The model measures the impact on net interest income relative to a base case scenario of hypothetical fluctuations in interest rates over the next 12 months. These simulations incorporate assumptions regarding balance sheet growth and mix, pricing and the repricing and maturity characteristics of the existing and projected balance sheet. The impact of interest rate derivatives, such as interest rate swaps, caps and floors, is also included in the model. Other interest rate-related risks such as prepayment, basis and option risk are also considered.

As of June 30, 2011, the model simulations projected that a 100 basis point increase in interest rates would not significantly impact net interest income and a 200 basis point increase in interest rates would result in negative variance in net interest income of 0.5%, relative to the base case over the next 12 months, while a decrease in interest rates of 25 basis points would result in a negative variance in net interest income of 0.7% relative to the base case over the next 12 months. The June 30, 2011 model simulations were impacted by the expectation that the Corporation will begin to pay interest on demand deposits in the third quarter of 2011, as further discussed below. As of June 30, 2010, the model simulations projected that 100 and 200 basis point increases in interest rates would result in positive variances in net interest income of 1.9% and 4.1%, respectively, relative to the base case over the next 12 months, while a decrease in interest rates of 25 basis points would result in a negative variance in net interest income of 0.5% relative to the base case over the next 12 months. The likelihood of a decrease in interest rates beyond 25 basis points as of June 30, 2011 and 2010 was considered remote given prevailing interest rate levels.

The Corporation has experienced significant growth in deposits in 2011 compared to 2010. The deposit growth funded a significant increase in fixed-rate securities and short-term interest-bearing deposits. Though short-term interest-bearing deposits are generally immediately impacted by changes in interest rates, the increase in fixed-rate securities coupled with the expectation that the Corporation will, in the third quarter of 2011, begin paying interest on demand deposits that were previously non-interest-bearing as a result of recent legislation, as further discussed below, the model simulations indicate that the Corporation’s balance sheet will become slightly liability sensitive relative to the base case over the next 12 months.

As mentioned above, financial regulatory reform legislation entitled the “Dodd-Frank Wall Street Reform and Consumer Protection Act” (the “Dodd-Frank Act”) repealed the federal prohibitions on the payment of interest on demand deposits, thereby permitting depository institutions to pay interest on business transaction and other accounts beginning July 21, 2011. Although the ultimate impact of this legislation on the Corporation has not yet been determined, the Corporation expects that it will begin to incur interest costs associated with demand deposits. As a result, the Corporation’s balance sheet is currently expected to become slightly liability sensitive. Because the interest rate that will ultimately be paid on these demand deposits depends upon a variety of factors, some of which are beyond the Corporation’s control, the Corporation assumed an aggressive pricing structure for the purposes of the model simulations discussed above. Should the actual interest rate paid on demand deposits be less than the rate assumed in the model simulations, or should the interest rate paid for such deposits become an administered rate with less direct correlation to movements in general market interest rates, the Corporation’s balance sheet could be less liability sensitive, or more asset sensitive, than the model simulations currently indicate.

As of June 30, 2011, the effect of a 200 basis point increase and a 25 basis point decrease in interest rates on the Corporation’s derivative holdings would not result in a significant variance in the Corporation’s net interest income.

The effects of hypothetical fluctuations in interest rates on the Corporation’s securities classified as “trading” under ASC Topic 320, “Investments - Debt and Equity Securities,” are not significant, and, as such, separate quantitative disclosure is not presented.

Controls and Procedures

As of the end of the period covered by this Quarterly Report on Form 10-Q, an evaluation was carried out by the Corporation’s management, with the participation of its Chief Executive Officer and Chief Financial Officer, of the effectiveness of the Corporation’s disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934). Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the disclosure controls and procedures were effective as of the end of the period covered by this report. No change in the Corporation’s internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) occurred during the last fiscal quarter that materially affected, or is reasonably likely to materially affect, the Corporation’s internal control over financial reporting.
