Notes to Consolidated Financial Statements
(Table amounts 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 our 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, insurance, brokerage, leasing, treasury management, capital markets advisory 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. All significant intercompany balances and transactions have been eliminated in consolidation. The accounting and financial reporting policies we follow 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 our 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 our consolidated financial statements, and notes thereto, for the year ended December 31, 2014, included in our Annual Report on Form 10-K filed with the SEC on February 5, 2015 (the “2014 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 and 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:

Reclassifications and Restatements. Certain items in prior financial statements have been reclassified to conform to the current presentation. Additionally, certain items in prior financial statements have been restated to reflect adjustments to initially reported provisional amounts recognized in business combinations so that the prior financial statements are reported as if the adjusted amounts had been known as of the measurement date of the business combination. In that regard, during 2015, we made acquisition valuation adjustments impacting certain assets acquired in connection with the acquisition of WNB Bancshares, Inc. (See Note 2 - Mergers and Acquisitions). As a result of these adjustments, our consolidated balance sheet as of December 31, 2014 reflects a $718 thousand increase in goodwill and a $718 thousand decrease in premises and equipment and our consolidated income statements for the three and six months ended June 30, 2014 reflect a $234 thousand increase in net income available to common shareholders when compared to previously reported amounts. The increase in net income impacted both basic and diluted earnings per common share for the three months ended June 30, 2014 and basic earnings per share for the six months ended June 30, 2014 by increasing previously reported amounts by $0.01, respectively. Other prior year comparative financial information reflects adjustments to our previously reported consolidated balance sheet as of June 30, 2014. These adjustments include a $2.0 million decrease in loans, a $777 thousand decrease in premises and equipment, a $5.6 million increase in goodwill, a $1.5 million decrease in intangible assets and a $911 thousand increase in shareholders' equity.

Note 2 - Mergers and Acquisitions
On May 30, 2014, we acquired WNB Bancshares, Inc. ("WNB"), including its subsidiary Western National Bank ("Western"), a privately-held bank holding company and bank located in the Permian Basin region of Texas. We purchased all of the outstanding shares of WNB for approximately $198.8 million. The total purchase price included $149.7 million of our common stock (2 million shares) and $49.1 million in cash. Western was integrated into Frost Bank as of the close of business on June 20, 2014.
The acquisition of WNB was accounted for using the acquisition method with all cash consideration funded through internal sources. The operating results of WNB are included with our results of operations since the date of acquisition. The total purchase price paid for the acquisition of WNB was allocated based on the fair values of the assets acquired and liabilities assumed as set forth below.

The loans acquired in this transaction were recorded at fair value with no carryover of any existing allowance for loan losses. Loans that were not deemed to be credit impaired at acquisition were subsequently considered as a part of our determination of the adequacy of the allowance for loan losses. Purchased credit-impaired loans, meaning those loans with evidence of credit quality deterioration at acquisition, were not significant. The core deposit intangible asset acquired in this transaction will be amortized using an accelerated method over a period of 10 years. Pro forma condensed consolidated results of operations assuming WNB had been acquired at the beginning of the reported periods are not presented because the effect of this acquisition was not considered significant based on the SEC significance tests.
Expenditures related to the acquisition of WNB totaled $4.8 million and $6.0 million during the three and six months ended June 30, 2014, respectively, and are reported as a component of other non-interest expense in the accompanying consolidated income statements.
As part of the approval process in connection with the acquisition of WNB, we agreed with the Federal Reserve that before bringing it any further expansionary proposals, except for proposed branches serving majority minority areas within our existing markets, we would enhance certain compliance programs, including those related to fair lending. We are currently working on these enhancements.

All mortgage-backed securities included in the above table were issued by U.S. government agencies and corporations. At June 30, 2015, approximately 97.6% of the securities in our municipal bond portfolio were issued by political subdivisions or agencies within the State of Texas, of which approximately 64.3% are either guaranteed by the Texas Permanent School Fund, which has a “triple A” insurer financial strength rating, or secured by U.S. Treasury securities via defeasance of the debt by the issuers. 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 $2.8 billion at June 30, 2015 and $3.0 billion and December 31, 2014.
During 2012, we reclassified certain securities from available for sale to held to maturity. The securities had an aggregate fair value of $2.3 billion with an aggregate net unrealized gain of $165.7 million ($107.7 million, net of tax) on the date of the transfer. The net unamortized, unrealized gain on the transferred securities included in accumulated other comprehensive income in the accompanying balance sheet as of June 30, 2015 totaled $77.8 million ($50.6 million, net of tax). This amount will be amortized out of accumulated other comprehensive income over the remaining life of the underlying securities as an adjustment of the yield on those securities.
As of June 30, 2015, securities with unrealized losses, segregated by length of impairment, were as follows:

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 to retain our 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 we will receive full value for the securities. Furthermore, as of June 30, 2015, 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 we 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, 2015, management believes the impairments detailed in the table above are temporary and no impairment loss has been realized in our consolidated income statement.
The amortized cost and estimated fair value of securities, excluding trading securities, at June 30, 2015 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. We have 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, our 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

Table of Contents

general economy. The properties securing our commercial real estate portfolio are diverse in terms of type and geographic location. This diversity helps reduce our 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, we avoid financing single-purpose projects unless other underwriting factors are present to help mitigate risk. We also utilize third-party experts to provide insight and guidance about economic conditions and trends affecting market areas we serve. In addition, management tracks the level of owner-occupied commercial real estate loans versus non-owner occupied loans. At June 30, 2015, approximately 52% of the outstanding principal balance of our 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 we may originate from time to time, we generally require the borrower to have had an existing relationship with us 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 completed 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 us 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.
We originate 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.
We maintain 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 our policies and procedures.
Concentrations of Credit. Most of our 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 our loan portfolio consists of commercial and industrial and commercial real estate loans. As of June 30, 2015, there were no concentrations of loans related to any single industry in excess of 10% of total loans other than energy loans, which totaled 15.8% of total loans.
Foreign Loans. We have 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, 2015 or December 31, 2014.
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, we consider the borrower’s debt service capacity through the analysis of current financial information, if available, and/or current information with regards to our 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.

As of June 30, 2015, non-accrual loans reported in the table above included $584 thousand related to loans that were restructured as “troubled debt restructurings” during 2015. See the section captioned “Troubled Debt Restructurings” elsewhere in this note. Had non-accrual loans performed in accordance with their original contract terms, we would have recognized additional interest income, net of tax, of approximately $364 thousand and $760 thousand for the three and six months ended June 30, 2015, compared to $355 thousand and $713 thousand for the three and six months ended June 30, 2014.

Impaired Loans. Loans are considered impaired when, based on current information and events, it is probable we 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 collectibility 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 us to reevaluate the fair value of collateral supporting impaired collateral dependent loans on at least an annual basis. While our policy is to comply with the regulatory guidelines, our general practice is to reevaluate the fair value of collateral supporting impaired collateral dependent loans on a quarterly basis. Thus, appraisals are generally not considered to be outdated, and we typically do not make any adjustments to the appraised values. The fair value of collateral supporting impaired collateral dependent loans is evaluated by our 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.

Troubled Debt Restructurings. The restructuring of a loan is considered a “troubled debt restructuring” if both (i) the borrower is experiencing financial difficulties and (ii) the creditor has granted a concession. Concessions may include interest rate reductions or below market interest rates, principal forgiveness, restructuring amortization schedules, reductions in collateral and other actions intended to minimize potential losses.
Troubled debt restructurings during the six months ended June 30, 2015 and June 30, 2014 are set forth in the following table.

The modifications during the reported periods primarily related to extending amortization periods, converting the loans to interest only for a limited period of time, consolidating notes and/or reducing collateral or interest rates. The modifications did not significantly impact our determination of the allowance for loan losses. As of June 30, 2015, there was one loan totaling $279 thousand restructured during the last year that was in excess of 90 days past due. During the six months ended June 30, 2015, we charged-off $88 thousand in connection with the restructuring of a commercial and industrial loan. Approximately $304 thousand of commercial and industrial loans restructured during the six months ended June 30, 2015 was related to a loan relationship previously restructured during 2014. During the six months ended June 30, 2014, we foreclosed upon certain commercial real estate loans that were restructured during 2013. We recognized $500 thousand of other real estate owned and no charge-offs in connection with these foreclosures. The aforementioned charge-offs and foreclosures did not significantly impact our determination of the allowance for loan losses.
Credit Quality Indicators. As part of the on-going monitoring of the credit quality of our 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.
We utilize a risk grading matrix to assign a risk grade to each of our 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.

Table of Contents

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, we monitor 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 commercial loans by class.

We have established maximum loan to value standards to be applied during the origination process of commercial and consumer real estate loans. We do 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, we reassess 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. We do not monitor loan-to-value ratios on a weighted-average portfolio-basis for commercial real estate loans having a calculated risk grade of 10 or higher as excess collateral from one borrower cannot be used to offset a collateral deficit for another borrower. When an

individual consumer real estate loan becomes past due by more than 10 days, the assigned relationship manager will begin collection efforts. We only reassess 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, we do 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 our 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 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 we become 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 any event the charge-off must be taken within specified delinquency time frames. Such delinquency time frames 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 127.1 at May 31, 2015 (most recent date available) and 129.4 at December 31, 2014. 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. Our 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 U.S. bank regulatory agencies. In that regard, our 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. Our 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 our control, including, among other things, the performance of our loan portfolio, the economy, changes in interest rates and the view of the regulatory authorities toward loan classifications. We monitor 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 we experience over time.
Our 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 us.
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. We calculate 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 (no less than annually) 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. Our 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 as a result of applying an environmental risk adjustment factor to the base historical loss allocation, (ii) the additional reserves allocated for loans to borrowers in distressed industries and (iii) the additional reserves allocated 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

20

Table of Contents

things, (i) the experience, ability and effectiveness of the bank’s lending management and staff; (ii) the effectiveness of our 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.
General valuation allowances also include amounts allocated for loans to borrowers in distressed industries. To determine the amount of the allocation for each loan portfolio segment, management calculates the weighted-average risk grade for all loans to borrowers in distressed industries by loan portfolio segment. A multiple is then applied to the amount by which the weighted-average risk grade for loans to borrowers in distressed industries exceeds the weighted-average risk grade for all pass-grade loans within the loan portfolio segment to derive an allocation factor for loans to borrowers in distressed industries. The amount of the allocation for each loan portfolio segment is the product of this allocation factor and the outstanding balance of pass-grade loans within the identified distressed industries that have a risk grade of 6 or higher. Management identifies potential distressed industries by analyzing industry trends related to delinquencies, classifications and charge-offs. At June 30, 2015 and December 31, 2014, certain segments of contractors were considered to be a distressed industry based on elevated levels of delinquencies, classifications and charge-offs relative to other industries within our loan portfolio. Furthermore, we determined, through a review of borrower financial information that, as a whole, contractors have experienced, among other things, decreased revenues, reduced backlog of work, compressed margins and little, if any, net income.
General valuation allowances also include allocations for groups of loans with similar risk characteristics that exceed certain concentration limits established by management and/or our board of directors. 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 exceptions that exceed specified risk grades. Additionally, general valuation allowances are provided for loans that did not undergo a separate, independent concurrence review during the underwriting process (generally those loans under $1.0 million at origination). Our allowance methodology for general valuation allowances also includes 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 adjustment for recoveries is based on the lower of annualized, year-to-date gross recoveries or the total gross recoveries by loan portfolio segment for the preceding four quarters, adjusted, when necessary, for expected future trends in recoveries. General valuation allowances are also allocated for general macroeconomic risk related to current economic trends and other quantitative and qualitative factors that could impact our loan portfolio segments.
Prior to the second quarter of 2015, general valuation allowances included allocations for loan agreement monitoring exceptions related to credit and/or collateral for certain loans that exceeded specified risk grades. During the second quarter of 2015, we concluded that this risk was more appropriately captured within our loan risk grade matrix through the assignment of a higher risk grade for loans having these exceptions and thus included as a component of our historical valuation allowances. General valuation allowance allocations for loan agreement monitoring exceptions totaled $3.1 million at March 31, 2015 and $2.2 million at December 31, 2014. There were no such general valuation allowance allocations as of June 30, 2015 as we have determined that these risks are now reflected in the historical valuation allowances. This change in our allowance methodology did not significantly impact the provision for loan losses recorded during the second quarter of 2015.

We monitor 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 we experience over time. In assessing the general macroeconomic trends/conditions, we analyze 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 us and our customers. With regard to assessing loan portfolio conditions, we analyze 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, we 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.

Note 7 - Commitments and Contingencies
Financial Instruments with Off-Balance-Sheet Risk. In the normal course of business, we enter into various transactions, which, in accordance with generally accepted accounting principles are not included in our consolidated balance sheets. We enter into these transactions to meet the financing needs of our 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. We minimize our exposure to loss under these commitments by subjecting them to credit approval and monitoring procedures.
We enter into contractual commitments to extend credit, normally with fixed expiration dates or termination clauses, at specified rates and for specific purposes. Substantially all of our 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 we issued 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, we would be required to fund the commitment. The maximum potential amount of future payments we could be required to make is represented by the contractual amount of the commitment. If the commitment were funded, we would be entitled to seek recovery from the customer. Our policies generally require that standby letter of credit arrangements contain security and debt covenants similar to those contained in loan agreements.
We consider the fees collected in connection with the issuance of standby letters of credit to be representative of the fair value of our obligation undertaken in issuing the guarantee. In accordance with applicable accounting standards related to guarantees, we defer 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 our potential obligations under the standby letter of credit guarantees.

Lease Commitments. We lease certain office facilities and office equipment under operating leases. Rent expense for all operating leases totaled $7.6 million and $15.3 million during the three and six months ended June 30, 2015 and $7.0 million and $13.5 million during the three and six months ended June 30, 2014. There has been no significant change in our expected future minimum lease payments since December 31, 2014. See the 2014 Form 10-K for information regarding these commitments.
Comprehensive Development Agreement. In July 2015, we entered into a comprehensive development agreement with the City of San Antonio and an independent third party whereby, under separate agreements, we will sell our current headquarters building to the City of San Antonio and various adjacent properties to the third party. The third party has agreed to build a new office building where we will be the primary tenant. The agreement to sell our headquarters building was finalized in July 2015 and is expected to close in mid-2016, subject to certain contingencies. Under the terms of the agreement, we will lease-back our headquarters building until such time that construction of the new building is completed, which is currently expected to be in 2019. While significant gains or losses may be realized on the various individual property sales completed in connection with the comprehensive development agreement, we do not expect any such gains or losses in the aggregate to have a significant impact on our operations.
Litigation. We are 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 our financial statements.
Note 8 - Capital and Regulatory Matters
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.
The Basel III Capital Rules became effective for Cullen/Frost and Frost Bank on January 1, 2015 (subject to a phase-in period for certain provisions). Quantitative measures established by the Basel III Capital Rules to ensure capital adequacy require the maintenance of minimum amounts and ratios (set forth in the table below) of Common Equity Tier 1 capital, Tier 1 capital and

Total 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 Common Equity Tier 1 capital consists of common stock and related paid-in capital, net of treasury stock, and retained earnings. In connection with the adoption of the Basel III Capital Rules, we elected to opt-out of the requirement to include most components of accumulated other comprehensive income in Common Equity Tier 1. Common Equity Tier 1 for both Cullen/Frost and Frost Bank is reduced by goodwill and other intangible assets, net of associated deferred tax liabilities and subject to transition provisions.
Tier 1 capital includes Common Equity Tier 1 capital and additional Tier 1 capital. For Cullen/Frost, additional Tier 1 capital at June 30, 2015 includes $144.5 million of 5.375% non-cumulative perpetual preferred stock and the allowable portion of the $133.0 million of trust preferred securities issued by our unconsolidated subsidiary trusts. Under the Basel III Capital Rules, trust preferred securities do not qualify as Tier 1 capital instruments and must be phased-out of Tier 1 capital. At June 30, 2015, $33.3 million of trust preferred securities were included in Cullen/Frost's additional Tier 1 capital. Beginning January 1, 2016, trust preferred securities may not be included in Tier 1 capital. Trust preferred securities excluded from additional Tier 1 capital may be included in Tier 2 capital, without limitation. Frost Bank did not have any additional Tier 1 capital beyond Common Equity Tier 1 as of June 30, 2015.
Total capital includes Tier 1 capital and Tier 2 capital. Tier 2 capital for both Cullen/Frost and Frost Bank includes a permissible portion of the allowance for loan losses. Tier 2 capital for Cullen/Frost also includes trust preferred securities that were excluded from Tier 1 capital and qualified subordinated debt. At June 30, 2015, Cullen/Frost's Tier 2 capital included $99.8 million of trust preferred securities and the permissible portion of our aggregate $100.0 million of floating rate subordinated notes (which decreases 20% per year during the final five years of the term of the notes) totaling $20.0 million at June 30, 2015. Our aggregate $100.0 million of floating rate subordinated notes mature on February 15, 2017. No portion of these notes will be permissible as a component of Tier 2 capital subsequent to February 15, 2016.
Prior to January 1, 2015, Cullen/Frost’s and Frost Bank’s Tier 1 capital consisted of total shareholders’ equity excluding accumulated other comprehensive income, goodwill and other intangible assets. Tier 1 capital for Cullen/Frost also included $144.5 million of 5.375% non-cumulative perpetual preferred stock and $133.0 million of trust preferred securities issued by our unconsolidated subsidiary trusts. Cullen/Frost’s and Frost Bank’s Total capital was comprised of Tier 1 capital for each entity plus a permissible portion of the allowance for loan losses and the permissible portion of outstanding subordinated debt. The permissible portion of our aggregate $100.0 million of floating rate subordinated notes totaled $40.0 million at December 31, 2014, and was included in total capital of Cullen/Frost.
The Common Equity Tier 1 (beginning in 2015), 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, among other things. The leverage ratio is calculated by dividing Tier 1 capital by adjusted quarterly average total assets, which exclude goodwill and other intangible assets, among other things.
When fully phased in on January 1, 2019, the Basel III Capital Rules will require Cullen/Frost and Frost Bank to maintain (i) a minimum ratio of Common Equity Tier 1 capital to risk-weighted assets of at least 4.5%, plus a 2.5% “capital conservation buffer” (which is added to the 4.5% Common Equity Tier 1 capital ratio as that buffer is phased in, effectively resulting in a minimum ratio of Common Equity Tier 1 capital to risk-weighted assets of at least 7.0% upon full implementation), (ii) a minimum ratio of Tier 1 capital to risk-weighted assets of at least 6.0%, plus the capital conservation buffer (which is added to the 6.0% Tier 1 capital ratio as that buffer is phased in, effectively resulting in a minimum Tier 1 capital ratio of 8.5% upon full implementation), (iii) a minimum ratio of Total capital (that is, Tier 1 plus Tier 2) to risk-weighted assets of at least 8.0%, plus the capital conservation buffer (which is added to the 8.0% total capital ratio as that buffer is phased in, effectively resulting in a minimum total capital ratio of 10.5% upon full implementation) and (iv) a minimum leverage ratio of 4.0%, calculated as the ratio of Tier 1 capital to average quarterly assets.
The implementation of the capital conservation buffer will begin on January 1, 2016 at the 0.625% level and be phased in over a four-year period (increasing by that amount on each subsequent January 1, until it reaches 2.5% on January 1, 2019). The Basel III Capital Rules also provide for a “countercyclical capital buffer” that is applicable to only certain covered institutions and does not have any current applicability to Cullen/Frost or Frost Bank.
The aforementioned capital conservation buffer is designed to absorb losses during periods of economic stress. Banking institutions with a ratio of Common Equity Tier 1 capital to risk-weighted assets above the minimum but below the conservation buffer (or below the combined capital conservation buffer and countercyclical capital buffer, when the latter is applied) will face constraints on dividends, equity repurchases and compensation based on the amount of the shortfall.

As of June 30, 2015, capital levels at Cullen/Frost and Frost Bank exceed all capital adequacy requirements under the Basel III Capital Rules on a fully phased-in basis. Based on the ratios presented above, capital levels as of June 30, 2015 at Cullen/Frost and Frost Bank exceed the minimum levels necessary to be considered “well capitalized.”
Cullen/Frost and Frost Bank are subject to the regulatory capital requirements administered by the Federal Reserve, and, for Frost Bank, the Federal Deposit Insurance Corporation (“FDIC”). 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 our financial statements. Management believes, as of June 30, 2015, that Cullen/Frost and Frost Bank meet all capital adequacy requirements to which they are subject.

Stock Repurchase Plans. From time to time, our board of directors has authorized stock repurchase plans. In general, stock repurchase plans allow us to proactively manage our capital position and return excess capital to shareholders. Shares purchased under such plans also provide us with shares of common stock necessary to satisfy obligations related to stock compensation awards. On April 30, 2015, our board of directors authorized a $100.0 million stock repurchase program, allowing us to repurchase shares of our common stock over a two-year period from time to time at various prices in the open market or through private transactions. Under the plan, we repurchased 140,571 shares at a total cost of $10.6 million during the three months ended June 30, 2015.
Dividend Restrictions. In the ordinary course of business, we are 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, 2015, Frost Bank could pay aggregate dividends of up to $353.0 million to Cullen/Frost without prior regulatory approval.
Although we have not done so to date, under the terms of the junior subordinated deferrable interest debentures that we have issued to Cullen/Frost Capital Trust II and WNB Capital Trust I, we have the right at any time during the term of the debentures to defer the payment of interest at any time or from time to time for an extension period not exceeding 20 consecutive quarterly periods with respect to each extension period. In the event that we have elected to defer interest on the debentures, we may not, with certain exceptions, declare or pay any dividends or distributions on our capital stock or purchase or acquire any of our capital stock.
Under the terms of our Series A Preferred Stock, in the event that we do not declare and pay dividends on our Series A Preferred Stock for the most recent dividend period, we may not, with certain exceptions, declare or pay dividends on, or purchase, redeem or otherwise acquire, shares of our common stock or any of our securities that rank junior to our Series A Preferred Stock.
Note 9 - 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. We utilize interest rate swaps, caps and floors to mitigate exposure to interest rate risk and to facilitate the needs of our customers. Our objectives for utilizing these derivative instruments is described below:
We have entered into certain interest rate swap contracts that are matched to specific fixed-rate commercial loans or leases that we have entered into with our 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, we 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 our 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 more fully discussed in the 2014 Form 10-K, we 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. The accumulated gain on the interest rate swaps upon settlement was deferred and amortized over the original lives of the underlying swap contracts. The amortization of the deferred accumulated gain ended in October 2014. As of June 30, 2014, the deferred accumulated gain applicable to the settled interest rate swap contracts included in accumulated other comprehensive income totaled $11.9 million ($7.7 million on an after-tax basis), all of which was recognized in interest income during 2014.
We have 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 we enter 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 a third party financial institution. In connection with each swap transaction, we agree 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, we agree to pay a third-party 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 our customer to effectively convert a variable rate loan to a fixed rate. Because we

act as an intermediary for our customer, changes in the fair value of the underlying derivative contracts for the most part offset each other and do not significantly impact our results of operations.
The notional amounts and estimated fair values of interest rate derivative contracts are presented in the following table. We obtain dealer quotations to value our 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.

Foreign Currency Derivatives. We enter into foreign currency forward contracts that are not designated as hedging instruments primarily to accommodate the business needs of our customers. Upon the origination of a foreign currency denominated transaction with a customer, we simultaneously enter into an offsetting contract with a third party financial institution to negate the exposure to fluctuations in foreign currency exchange rates. We also utilize foreign currency forward contracts that are not designated as hedging instruments to mitigate the economic effect of fluctuations in foreign currency exchange rates on foreign currency holdings and certain short-term, non-U.S. dollar denominated loans.

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. 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.

rate swap contracts included in accumulated other comprehensive income totaled $11.9 million ($7.7 million on an after-tax basis), all of which was recognized in interest income during 2014.
As stated above, we enter into non-hedge related derivative positions primarily to accommodate the business needs of our customers. Upon the origination of a derivative contract with a customer, we simultaneously enter into an offsetting derivative contract with a third party financial institution. We recognize immediate income based upon the difference in the bid/ask spread of the underlying transactions with our customers and the third party. Because we act only as an intermediary for our customer, subsequent changes in the fair value of the underlying derivative contracts for the most part offset each other and do not significantly impact our results of operations.

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 our Asset/Liability Management Committee. Our credit exposure on interest rate swaps is limited to the net favorable value and interest payments of all swaps by each counterparty, while our credit exposure on commodity swaps/options and foreign currency forward contracts is limited to the net favorable value of all contracts 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 our 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.
Our credit exposure relating to interest rate swaps, commodity swaps/options and foreign currency forward contracts with bank customers was approximately $33.9 million at June 30, 2015. This credit exposure is partly mitigated as transactions with customers are generally secured by the collateral, if any, securing the underlying transaction being hedged. Our credit exposure, net of collateral pledged, relating to interest rate swaps, commodity swaps/options and foreign currency forward contracts with upstream financial institution counterparties was approximately $8.4 million at June 30, 2015. This amount was primarily related to excess collateral we posted to counterparties. Collateral levels for upstream financial institution counterparties are monitored and adjusted as necessary. See Note 10 – Balance Sheet Offsetting for additional information regarding our credit exposure with upstream financial institution counterparties.
The aggregate fair value of securities we posted as collateral related to derivative contracts totaled $19.2 million at June 30, 2015. At such date, we also had $14.0 million in cash collateral on deposit with other financial institution counterparties.

Note 10 - Balance Sheet Offsetting and Repurchase Agreements
Balance Sheet Offsetting. Certain financial instruments, including resell and repurchase agreements and derivatives, may be eligible for offset in the consolidated balance sheet and/or subject to master netting arrangements or similar agreements. Our derivative transactions with upstream financial institution counterparties are generally executed under International Swaps and Derivative Association (“ISDA”) master agreements which include “right of set-off” provisions. In such cases there is generally a legally enforceable right to offset recognized amounts and there may be an intention to settle such amounts on a net basis. Nonetheless, we do not generally offset such financial instruments for financial reporting purposes.
Information about financial instruments that are eligible for offset in the consolidated balance sheet as of June 30, 2015 is presented in the following tables.

Repurchase Agreements. We utilize securities sold under agreements to repurchase to facilitate the needs of our customers and to facilitate secured short-term funding needs. Securities sold under agreements to repurchase are stated at the amount of cash received in connection with the transaction. We monitor collateral levels on a continuous basis. We may be required to provide additional collateral based on the fair value of the underlying securities. Securities pledged as collateral under repurchase agreements are maintained with our safekeeping agents.
The remaining contractual maturity of repurchase agreements in the consolidated balance sheets as of June 30, 2015 and December 31, 2014 is presented in the following tables.

Note 12 - 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 our 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 net income available to common shareholders, net earnings allocated to common stock and the number of shares used in the calculation of basic and diluted earnings per common share.

Net deferred tax liabilities totaled $17.1 million at June 30, 2015 and $56.6 million at December 31, 2014. No valuation allowance for deferred tax assets was recorded at June 30, 2015 as management believes 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. Interest and/or penalties related to income taxes are reported as a component of income tax expense. Such amounts were not significant during the reported periods.
We file income tax returns in the U.S. federal jurisdiction. We are no longer subject to U.S. federal income tax examinations by tax authorities for years before 2011.
Note 15 - Other Comprehensive Income (Loss)
The before and after tax amounts allocated to each component of other comprehensive income (loss) are presented in the following table. Reclassification adjustments related to securities available for sale are included in net gain (loss) on securities transactions in the accompanying consolidated statements of income. The change in the net actuarial gain/loss on defined-benefit post-retirement benefit plans is included in the computation of net periodic pension expense (see Note 13 – Defined Benefit Plans). Reclassification adjustments related to interest rate swaps on variable-rate loans are included in interest income and fees on loans in the accompanying consolidated statements of income.

Note 16 – Operating Segments
We are managed under a matrix organizational structure whereby our two primary operating segments, Banking and Frost Wealth Advisors, overlap a regional reporting structure. The regions are primarily based upon geographic location and include Austin, Corpus Christi, Dallas, Fort Worth, Houston, Permian Basin, Rio Grande Valley, San Antonio and Statewide. We are 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.
Banking and Frost Wealth Advisors are delineated by the products and services that each segment offers. The Banking operating segment includes both commercial and consumer banking services and Frost Insurance Agency and Frost Securities. 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 and human resources consulting services. Prior to June 30, 2015, Frost Securities provided advisory and private equity services to middle market companies. The operations of Frost Securities were discontinued and the entity was closed effective June 30, 2015. The Frost Wealth Advisors operating segment includes fee-based services within private trust, retirement services, and financial management services, including personal wealth management and securities brokerage services. A 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 our 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 our consolidated entity except for the following items, which impact the Banking and Frost Wealth Advisors 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.
We use a match-funded transfer pricing process to assess operating segment performance. The process helps us 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.

Note 17 – 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, we utilize 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 our creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. Our 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 our 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 below. 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 our monthly and/or quarterly valuation process.
Financial Assets and Financial Liabilities: Financial assets and financial liabilities measured at fair value on a recurring basis include the following:
Securities Available for Sale. U.S. Treasury securities are reported at fair value utilizing Level 1 inputs. Other securities classified as available for sale are reported at fair value utilizing Level 2 inputs. For these securities, we obtain fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things.
We review the prices supplied by the independent pricing service, as well as their underlying pricing methodologies, for reasonableness and to ensure such prices are aligned with traditional pricing matrices. In general, we do not purchase investment portfolio securities that are esoteric or that have a complicated structure. Our entire portfolio consists of traditional investments, nearly all of which are U.S. Treasury obligations, federal agency bullet or mortgage pass-through securities, or general obligation or revenue based municipal bonds. Pricing for such instruments is fairly generic and is easily obtained. From time to time, we will validate prices supplied by the independent pricing service by comparison to prices obtained from third-party sources or derived using internal models.
Trading Securities. U.S. Treasury securities and exchange-listed common stock are reported at fair value utilizing Level 1 inputs. Other securities classified as trading are reported at fair value utilizing Level 2 inputs in the same manner as described above for securities available for sale.
Derivatives. Derivatives are generally reported at fair value utilizing Level 2 inputs, except for foreign currency contracts, which are reported at fair value utilizing Level 1 inputs. We obtain dealer quotations and utilize internally developed valuation models to value commodity swaps/options. We utilize internally developed valuation models and/or third-party models with observable market data inputs to validate the valuations provided by the dealers. Though there has never been a significant discrepancy in the valuations, should such a significant discrepancy arise, we would obtain price verification from a third-party

41

Table of Contents

dealer. We utilize internal valuation models with observable market data inputs to estimate fair values of customer interest rate swaps, caps and floors. We also obtain dealer quotations for these derivatives for comparative purposes to assess the reasonableness of the model valuations. In cases where significant credit valuation adjustments are incorporated into the estimation of fair value, reported amounts are considered to have been derived utilizing Level 3 inputs.
For purposes of potential valuation adjustments to our derivative positions, we evaluate the credit risk of our counterparties as well as ours. Accordingly, we have considered factors such as the likelihood of our default and the default of our counterparties, our net exposures and remaining contractual life, among other things, in determining if any fair value adjustments related to credit risk are required. Counterparty exposure is evaluated by netting positions that are subject to master netting arrangements, as well as considering the amount of collateral securing the position. We review our counterparty exposure on a regular basis, and, when necessary, appropriate business actions are taken to adjust the exposure. We also utilize this approach to estimate our own credit risk on derivative liability positions. To date, we have not realized any significant losses due to a counterparty’s inability to pay any net uncollateralized position. The change in value of derivative assets and derivative liabilities attributable to credit risk was not significant during the reported periods.
The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis as of June 30, 2015 and December 31, 2014, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value:

Derivative assets, measured at fair value on a recurring basis using significant unobservable (Level 3) inputs during the reported periods consist of interest rate swaps sold to loan customers. The significant unobservable (Level 3) inputs used in the fair value measurement of these interest rate swaps sold to loan customers primarily relate to the probability of default and loss severity in the event of default. The probability of default is determined by the underlying risk grade of the loan (see Note 4 – Loans) underlying the interest rate swap in that the probability of default increases as a loan’s risk grade deteriorates, while the loss severity is estimated through an analysis of the collateral supporting both the underlying loan and interest rate swap. Generally, a change in the assumption used for the probability of default is accompanied by a directionally similar change in the assumption used for the loss severity. As of June 30, 2015, the weighted-average risk grade of loans underlying interest rate swaps measured at fair value using significant unobservable (Level 3) inputs was 11.0. The weighted-average loss severity in the event of default on the interest rate swaps was 20%. A reconciliation of the beginning and ending balances of derivative assets measured at fair value on a recurring basis using significant unobservable (Level 3) inputs is not presented as such amounts were not significant during the reported periods.
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 reported periods 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, typically in the case of real estate collateral, or Level 3 inputs based on customized discounting criteria, typically in the case of non-real estate collateral such as inventory, accounts receivable, equipment or other business assets.
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 reported periods.

Non-Financial Assets and Non-Financial Liabilities: We do not have any 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

reported periods 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.

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 our provision for loan losses. Regulatory guidelines require us to reevaluate the fair value of other real estate owned on at least an annual basis. Our policy is to comply with the regulatory guidelines. Accordingly, appraisals are never considered to be outdated, and we do not make any adjustments to the appraised values.
Financial Accounting Standards Board (“FASB”) ASC Topic 825 “Financial Instruments,” 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 2014 Form 10-K.

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, we had no financial instruments measured at fair value under the fair value measurement option.

Note 18 - Accounting Standards Updates
ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)." ASU 2014-09 implements a common revenue standard that clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. ASU 2014-09 was originally going to be effective for us on January 1, 2017; however, the FASB recently deferred the effective date by one year which would make ASU 2014-09 effective for us on January 1, 2018. We are currently evaluating the potential impact of ASU 2014-09 on our financial statements.
ASU 2014-11, “Transfers and Servicing (Topic 860).” ASU 2014-11 requires that repurchase-to-maturity transactions be accounted for as secured borrowings consistent with the accounting for other repurchase agreements. In addition, ASU 2014-11 requires separate accounting for repurchase financings, which entails the transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty. ASU 2014-11 requires entities to disclose certain information about transfers accounted for as sales in transactions that are economically similar to repurchase agreements. In addition, ASU 2014-11 requires disclosures related to collateral, remaining contractual tenor and of the potential risks associated with repurchase agreements, securities lending transactions and repurchase-to-maturity transactions. ASU 2014-11 became effective for us on January 1, 2015 and did not have a significant impact on our financial statements. The new disclosures required by ASU 2014-11 are included in Note 10 - Balance Sheet Offsetting and Repurchase Agreements.
ASU 2015-01, “Income Statement - Extraordinary and Unusual Items (Subtopic 225-20) – Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items.” ASU 2015-01 eliminates from U.S. GAAP the concept of extraordinary items, which, among other things, required an entity to segregate extraordinary items considered to be unusual and infrequent from the results of ordinary operations and show the item separately in the income statement, net of tax, after income from continuing operations. ASU 2015-01 is effective for us beginning January 1, 2016, though early adoption is permitted. ASU 2015-01 is not expected to have a significant impact on our financial statements.
ASU 2015-02, “Consolidation (Topic 810) – Amendments to the Consolidation Analysis.” ASU 2015-02 implements changes to both the variable interest consolidation model and the voting interest consolidation model. ASU 2015-02 (i) eliminates certain criteria that must be met when determining when fees paid to a decision maker or service provider do not represent a variable interest, (ii) amends the criteria for determining whether a limited partnership is a variable interest entity and (iii)  eliminates the presumption that a general partner controls a limited partnership in the voting model. ASU 2015-02 will be effective for us on January 1, 2016 and is not expected to have a significant impact on our financial statements.
ASU 2015-03, “Interest - Imputation of Interest (Subtopic 835-30) – Simplifying the Presentation of Debt Issuance Costs. ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by the amendments in ASU 2015-03. ASU 2015-03 will be effective for us on January 1, 2016, though early adoption is permitted. ASU 2015-03 is not expected to have a significant impact on our financial statements.
ASU 2015-05, “Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40) – Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” ASU 2015-05 addresses accounting for fees paid by a customer in cloud computing arrangements such as (i) software as a service, (ii) platform as a service, (iii) infrastructure as a service and (iv) other similar hosting arrangements. ASU 2015-05 provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. ASU 2015-05 will be effective for us on January 1, 2016 and is not expected to have a significant impact on our financial statements.

Application of Critical Accounting Policies and Accounting Estimates
The accounting and reporting policies we follow 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 we base estimates on historical experience, current information and other factors deemed to be relevant, actual results could differ from those estimates.
We consider 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 our 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 and Note 4 - Loans in the notes to consolidated financial statements and the sections captioned “Application of Critical Accounting Policies and Accounting Estimates” and “Allowance for Loan Losses” in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in the 2014 Form 10-K. There have been no significant changes in our application of critical accounting policies related to the allowance for loan losses since December 31, 2014.
Overview
A discussion of our 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.

Net income available to common shareholders increased $6.4 million, or 9.9%, for the three months ended June 30, 2015 and increased $17.3 million, or 14.0%, for the six months ended June 30, 2015 compared to the same periods in 2014.The increase during the three months ended June 30, 2015 was primarily the result of a $12.8 million increase in net interest income, a $2.1 million decrease in the provision for loan losses and a $939 thousand decrease in income tax expense and partly offset by an $9.3 million increase in non-interest expense and a $168 thousand decrease in non-interest income. The increase during the six months ended June 30, 2015 was primarily the result of a $33.2 million increase in net interest income, a $5.6 million increase in non-interest income, an $953 thousand decrease in income tax expense and a $489 thousand decrease in the provision for loan losses partly offset by a $22.9 million increase in non-interest 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 our largest source of revenue, representing 69.1% of total revenue during the first six months of 2015. 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. Our 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 2014 and through the second quarter of 2015. Our loan portfolio is also impacted, to a lesser extent, by changes in the London Interbank Offered Rate (LIBOR). At June 30, 2015, the one-month and three-month U.S. dollar LIBOR rates were 0.19% and 0.28%, respectively, while at June 30, 2014, the one-month and three-month U.S. dollar LIBOR rates were 0.16% and 0.23%, respectively. The intended

Table of Contents

federal funds rate, which is the cost of immediately available overnight funds, remained at zero to 0.25% for the entire year in 2014 and through the second quarter of 2015.
Our balance sheet has historically been asset sensitive, meaning that earning assets generally reprice more quickly than interest-bearing liabilities. Therefore, our 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 our balance sheet less sensitive to changes in interest rates, we entered into various interest rate swaps which effectively converted certain variable-rate loans into fixed-rate instruments for a period of seven years. As a result of this action, our balance sheet was more interest-rate neutral and changes in interest rates had a less significant impact on our 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 was 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 our balance sheet. The accumulated gain on the interest rate swaps upon settlement was deferred and amortized over the original lives of the underlying swap contracts. The amortization of the deferred accumulated gain ended in October 2014. See Note 9 - 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.
We are 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 our net interest income and net interest margin in a rising interest rate environment. 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. To date, we have not experienced any significant additional interest costs as a result of the repeal; however, we may begin to incur interest costs associated with certain demand deposits in the future as market conditions warrant. See Item 3. Quantitative and Qualitative Disclosures About Market Risk elsewhere in this report for information about the expected impact of this legislation on our sensitivity to interest rates. Further analysis of the components of our 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.

Taxable-equivalent net interest income for the three months ended June 30, 2015 increased $20.9 million or 10.5%, while taxable-equivalent net interest income for the six months ended June 30, 2015 increased $49.8 million, or 12.9%, compared to the same periods in 2014. The increases during the three and six months ended June 30, 2015 were primarily related to increases in the average volume of interest-earning assets. The average volume of interest-earning assets for the three months ended June 30, 2015 increased $2.6 billion, while average volume of interest-earning assets for the six months ended June 30, 2015 increased $3.1 billion compared to the same periods in 2014. The increase in earning assets during the three months ended June 30, 2015 reflected a $2.7 billion increase in average securities and a $1.2 billion increase in average loans, partly offset by a $1.3 billion decrease in average interest-bearing deposits. The increase in earning assets during the six months ended June 30, 2015 reflected a $2.8 billion increase in average securities and a $1.3 billion increase in average loans, partly offset by a $1.0 billion decrease in average interest-bearing deposits. The increase in the average volume of interest-earning assets during the three and six months ended June 30, 2015 was partly related to the acquisition of WNB during the second quarter of 2014 in which we acquired cash and cash equivalents totaling $879.7 million, loans totaling $670.6 million and securities totaling $154.2 million.
The net interest margin decreased 2 basis points from 3.49% during the three months ended June 30, 2014 to 3.47% during the three months ended June 30, 2015 and decreased 2 basis points from 3.46% during the six months ended June 30, 2014 to 3.44% during the six months ended June 30, 2015. The net interest margin during 2015 was negatively impacted by decreases in the average yields on loans and securities while the net interest margin was positively impacted by a decrease in the relative proportion of average interest-earning assets invested in lower-yielding, interest-bearing deposits during the three and six months ended June 30, 2015 compared to the same periods in 2014. These items are more fully discussed below. The average yield on

49

Table of Contents

interest-earning assets decreased 3 basis points from 3.55% during the three months ended June 30, 2014 to 3.52% during the three months ended June 30, 2015 and decreased 3 basis points from 3.52% during the six months ended June 30, 2014 to 3.49% during the six months ended June 30, 2015. The average cost of funds decreased 1 basis point from 0.10% during both the three and six months ended June 30, 2014 to 0.09% during both the three and six months ended June 30, 2015. 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. As stated above, market interest rates have remained at historically low levels during the reported periods. The effect of lower average market interest rates during the reported periods on the average yield on average interest-earning assets was partly limited through October 2014 because of the aforementioned interest rate swaps on variable-rate loans.
The average volume of loans during the first six months of 2015 increased $1.3 billion compared to the same period in 2014. Loans made up approximately 43.4% of average interest-earning assets during the first six months of both 2015 and 2014. As discussed above, we acquired $670.6 million in loans in connection with the acquisition of WNB during the second quarter of 2014. 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 yield on loans decreased 56 basis points from 4.47% during the first six months of 2014 to 3.91% during the first six months of 2015. The average yield on loans was negatively impacted by lower average spreads due to increased competition in loan pricing during the first six months of 2015 compared to the same period in 2014. Furthermore, the decrease in the average yield on loans was also partly related to the aforementioned completion of the amortization of the deferred accumulated gain applicable to the settled interest rate swap contracts in October 2014. The amortization of the deferred accumulated gain positively impacted our average yield on loans by 38 basis points during the first six months of 2014. In an effort to offset the loss of the amortization and its positive effect on our net interest income, we utilized $840 million in excess liquidity to purchase municipal securities during the third and fourth quarters of 2014. The higher yields associated with these securities relative to the yield that would have been received had these funds continued to be held as interest-bearing deposits and federal funds sold replaced the revenue stream from the amortization of the deferred accumulated gain applicable to the settled interest rate swaps so that our net interest income was not significantly impacted.
The average volume of securities during the first six months of 2015 increased $2.8 billion compared to the same period in 2014. Securities made up approximately 44.9% of average interest-earning assets during the first six months of 2015 compared to 38.8% during the first six months of 2014. This increase was primarily related to the investment of excess liquidity from deposit growth, which included the aforementioned $840 million investment in municipal securities. The average yield on securities was 3.94% during the first six months of 2015, decreasing 1 basis point from 3.95% during the first six months of 2014. The average yield on securities was negatively impacted by a decrease in the proportion of higher-yielding tax-exempt securities to total securities to 52.0% during the first six months of 2015 from 52.5% for the same period in 2014. The average yield on securities was positively impacted by increases in the average yields of both taxable and tax-exempt securities during the first six months of 2015 compared to the same period in 2014. The average yield on taxable and non-taxable securities was 2.14% and 5.59%, respectively, during the first six months of 2015, each increasing 1 basis point from 2.13% and 5.58%, respectively, during the first six months of 2014.
Average federal funds sold, resell agreements and interest-bearing deposits during the first six months of 2015 decreased $1.0 billion compared to the same period in 2014. Federal funds sold, resell agreements and interest-bearing deposits made up approximately 11.7% of average interest-earning assets during the first six months of 2015 compared to 17.8% during the first six months of 2014. The combined average yield on federal funds sold, resell agreements and interest-bearing deposits was 0.26% during the first six months of both 2015 and 2014. The decrease in average federal funds sold, resell agreements and interest-bearing deposits was primarily related to the reinvestment of such funds into higher-yielding loans and securities.
Average deposits increased $2.9 billion during the first six months of 2015 compared to the same period in 2014. Average deposits in 2015 were impacted by the acquisition of $1.6 billion in deposits in connection with the acquisition of WNB on May 30, 2014. Average interest-bearing deposits during the first six months of 2015 increased $1.4 billion compared to the same period in 2014, while average non-interest-bearing deposits during the first six months of 2015 increased $1.5 billion compared to the same period in 2014. The ratio of average interest-bearing deposits to total average deposits was 58.2% during the first six months of 2015 compared to 59.5% during the first six months of 2014. 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 0.07% and 0.04%, respectively, during the first six months of 2015 and 0.08% and 0.05%, respectively, during the first six months of 2014.
Our 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 3.40% during the first six months of 2015 compared to 3.42% during the first six months of 2014. 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.

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 $2.9 million and $11.0 million for the three and six months ended June 30, 2015 compared to $4.9 million and $11.5 million for the three and six months ended June 30, 2014. See the section captioned “Allowance for Loan Losses” elsewhere in this discussion for further analysis of the provision for loan losses.

Trust and investment management fees for the three and six months ended June 30, 2015 decreased $276 thousand, or 1.0%, and increased $1.5 million, or 2.8%, compared to the same periods in 2014, respectively. Investment fees are the most significant component of trust and investment management fees, making up approximately 77.6% and 74.6% of total trust and investment management fees for the first six months of 2015 and 2014, 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 decrease in trust and investment management fees during the three months ended June 30, 2015 compared to the same period in 2014 was primarily the result of decreases in oil and gas fees (down $1.0 million) and securities lending fees (down $838 thousand) partly offset by increases in trust investment fees (up $1.4 million) and estate fees (up $117 thousand). The increase in trust and investment management fees during the six months ended June 30, 2015 compared to the same period in 2014 was primarily the result of increases in trust investment fees (up $2.7 million) and estate fees (up $546 thousand) partly offset by decreases in securities lending income (down $929 thousand), oil and gas fees (down $624 thousand) and real estate fees (down $230 thousand). The increases in trust investment fees during 2015 were partly due to higher average equity valuations and an increase in the number of accounts. The increases in estate fees during 2015 were partly related to an increase in the number of estates that were settled. The decreases in oil and gas fees during 2015 were partly due to lower prices and decreased production. Securities lending fees decreased during 2015 as we discontinued our securities lending operations during the first quarter of 2015 in part due to the negative impact securities lending transactions would have had on our regulatory capital ratios under the newly effective Basel III capital rules. See Note 8 - Capital and Regulatory Matters in the accompanying notes to consolidated financial statements included elsewhere in this report. The decrease in real estate fees during the six months ended June 30, 2015 was related to higher fees during 2014 due to a single, significant transaction.
At June 30, 2015, trust assets, including both managed assets and custody assets, were primarily composed of equity securities (47.2% of assets), fixed income securities (39.8% of assets) and cash equivalents (7.2% of assets). The estimated fair value of these assets was $30.6 billion (including managed assets of $13.0 billion and custody assets of $17.6 billion) at June 30, 2015,

compared to $30.5 billion (including managed assets of $13.0 billion and custody assets of $17.5 billion) at December 31, 2014 and $29.9 billion (including managed assets of $12.6 billion and custody assets of $17.3 billion) at June 30, 2014.
Service Charges on Deposit Accounts. Service charges on deposit accounts for the three and six months ended June 30, 2015 decreased $429 thousand, or 2.1%, and $626 thousand, or 1.5%, compared to the same periods in 2014. The decreases were primarily due to decreases in service charges on commercial accounts (down $211 thousand and $194 thousand during the three and six months ended June 30, 2015, respectively), overdraft/insufficient funds charges on consumer accounts (down $164 thousand and $283 thousand during the three and six months ended June 30, 2015, respectively) and service charges on consumer accounts (down $67 thousand and $103 thousand during the three and six months ended June 30, 2015, respectively). Overdraft/insufficient funds charges totaled $7.7 million ($6.0 million consumer and $1.7 million commercial) during the three months ended June 30, 2015 compared to $7.9 million ($6.1 million consumer and $1.8 million commercial) during the same period in 2014. Overdraft/insufficient funds charges totaled $15.1 million ($11.6 million consumer and $3.5 million commercial) during the six months ended June 30, 2015 compared to $15.4 million ($11.9 million consumer and $3.5 million commercial) during the same period in 2014.
Insurance Commissions and Fees. Insurance commissions and fees for the three and six months ended June 30, 2015 increased $307 thousand, or 3.1% and $1.8 million, or 7.9%, compared to the same periods in 2014. The increase during the three months ended June 30, 2015 was related to increases in commission income (up $219 thousand) and contingent commissions (up $88 thousand). The increase during the six months ended June 30, 2015 was related to increases in contingent commissions (up $1.4 million) and commission income (up $374 thousand). Insurance commissions and fees include contingent commissions totaling $674 thousand and $4.5 million during the three and six months ended June 30, 2015 and $586 thousand and $3.1 million during the three and six months ended June 30, 2014. 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 mostly received during the first quarter of each year. These commissions totaled $3.5 million and $2.0 million during the six months ended June 30, 2015 and 2014, respectively. 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 $555 thousand and $990 thousand during the three and six months ended June 30, 2015 and $594 thousand and $1.1 million during the three and six months ended June 30, 2014.
Interchange and Debit Card Transaction Fees. Interchange fees, or “swipe” fees, are charges that merchants pay to us and other card-issuing banks for processing electronic payment transactions. Interchange and debit card transaction fees consist of income from check card usage, point of sale income from PIN-based debit card transactions and ATM service fees. Interchange and debit card transaction fees for the three and six months ended June 30, 2015 increased $290 thousand, or 6.3%, and $690 thousand, or 7.8%, compared to the three and six months ended June 30, 2014. The increases were primarily due to increases in income from debit card transactions (up $253 thousand and $508 thousand during the three and six months ended June 30, 2015, respectively) and ATM service fees (up $22 thousand and $182 thousand during the three and six months ended June 30, 2015, respectively).
Federal Reserve rules applicable to financial institutions that have assets of $10 billion or more provide that the maximum permissible interchange fee for an electronic debit transaction is the sum of 21 cents per transaction and 5 basis points multiplied by the value of the transaction. An upward adjustment of no more than 1 cent to an issuer's debit card interchange fee is allowed if the card issuer develops and implements policies and procedures reasonably designed to achieve certain fraud-prevention standards. The Federal Reserve also has rules governing routing and exclusivity that require issuers to offer two unaffiliated networks for routing transactions on each debit or prepaid product.
Other Charges, Commissions and Fees. Other charges, commissions and fees for the three months ended June 30, 2015 increased $1.6 million, or 18.3%, compared to the same period in 2014. The increase in other charges, commissions and fees included increases in income from capital markets fees related to advisory services (up $1.0 million), letters of credit fees (up $160 thousand), commission income related to the sale of money market accounts (up $108 thousand), income from the sale of mutual funds (up $104 thousand), origination fees collected on loans that did not fund (up $102 thousand), among other things.
Other charges, commissions and fees for the six months ended June 30, 2015 increased $1.8 million, or 10.7%, compared to the same period in 2014. The increase in other charges, commissions and fees included increases in income from capital markets fees related to advisory services (up $1.1 million), letters of credit fees (up $321 thousand), income from the sale of mutual funds (up $310 thousand), commission income related to the sale of money market accounts (up $291 thousand), unused balance fees on loan commitments (up $254 thousand) and origination fees collected on loans that did not fund (up $242 thousand), among other things. These increases were partly offset by decreases in income related to the sale of annuities (down $614 thousand) and human resources consulting fee income (down $264 thousand), among other things.

Net Gain/Loss on Securities Transactions. During the first quarter of 2015, we sold an available-for-sale U.S. Treasury security with an amortized cost totaling $223.8 million and realized a gain of $228 thousand on the sale. The security sold had a short term and low yield. The proceeds from the sale of this security were reinvested into longer-term, higher-yielding securities.
Other Non-Interest Income. Other non-interest income for the three months ended June 30, 2015 decreased $1.6 million, or 18.1%, compared to the same period in 2014. The decrease in other non-interest income was due to decreases in sundry and other miscellaneous income (down $2.2 million), mineral interest income (down $955 thousand), income from customer derivative activities (down $356 thousand) and lease rental income (down $104 thousand) partly offset by increases in income from public finance underwriting fees (up $1.6 million) and earnings on life insurance policies (up $409 thousand). Other non-interest income for the six months ended June 30, 2015 increased $180 thousand, or 1.2%, compared to the same period in 2014. The increase in other non-interest income was due in part to increases in income from public finance underwriting fees (up $2.1 million); income from customer derivative activities (up $726 thousand); earnings on life insurance policies (up $613 thousand); partly offset by a decrease in mineral interest income (down $2.0 million), sundry and other miscellaneous income (down $1.9 million) and lease rental income (down $179 thousand). During 2015, sundry and other miscellaneous income included, among other things, $348 thousand related to a recovery of a prior write-off, $325 thousand related to an insurance settlement and $159 thousand related to a distribution received on a small business investment company ("SBIC") investment. During 2014, sundry and other miscellaneous income included, among other things, $1.3 million related to a distribution received on an SBIC investment and $1.3 million related to a recovery of interest on loans charged-off in previous years. Mineral interest income is related to bonus, rental and shut-in payments and oil and gas royalties received from severed mineral interests on property owned by our wholly-owned non-banking subsidiary Main Plaza Corporation. The decrease in mineral interest income was partly related to lower energy prices and a decrease in production. The variation in income from customer derivative activities during the comparable periods was primarily related to fluctuations in the volume of customer interest rate swap transactions, which impacted the level of fees we recognized. The increase in income from public finance underwriting fees was primarily related to transaction volumes.

Total non-interest expense for the three and six months ended June 30, 2015 increased $9.3 million, or 5.7%, and $22.9 million, or 7.1%, compared to the same periods in 2014. The increase in non-interest expense was particularly impacted by the acquisition of WNB during the second quarter of 2014. Changes in the various components of non-interest expense are discussed below.
Salaries and Wages. Salaries and wages for the three and six months ended June 30, 2015 increased $6.2 million, or 8.7%, and $12.0 million, or 8.5%, compared to the same periods in 2014. The increases were primarily related to an increase in the number of employees, partly related to the acquisition of WNB, and normal annual merit and market increases and, to a lesser extent, increases in stock-based compensation, incentive compensation and overtime.
Employee Benefits. Employee benefits expense for the three months ended June 30, 2015 increased $2.5 million, or 17.1%, compared to the same period in 2014. The increase was related to increases in expenses related to our defined benefit retirement plans (up $1.3 million), payroll taxes (up $431 thousand), expenses related to our 401(k) and profit sharing plans (up $333 thousand) and medical insurance expense (up $340 thousand). Employee benefits expense for the six months ended June 30, 2015 increased $5.4 million, or 16.7%, compared to the same period in 2014. The increase was related to increases in expenses related to our defined benefit retirement plans (up $2.5 million), expenses related to our 401(k) and profit sharing plans (up $1.1 million), medical insurance expense (up $680 thousand) and payroll taxes (up $630 thousand). Other than expenses related to our defined benefit retirement plans, the aforementioned increases in the various categories of employee benefits expense were related to an increase in the number of employees, which includes those added in connection with the acquisition of WNB.

During the three and six months ended June 30, 2015, we recognized combined net periodic pension expenses of $818 thousand and $1.6 million, respectively, related to our defined benefit retirement plans compared to combined net periodic pension benefits of $456 thousand and $913 thousand during the same periods in 2014. The increase in net periodic pension expense during 2015 was partly related to a decrease in the discount rate as well as changes in other actuarial assumptions. Our 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, we still have 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, 2015 increased $2.7 million, or 19.6%, and $4.8 million, or 18.1%, compared to the same periods in 2014. The increase during the three months ended June 30, 2015 was primarily related to increases in lease expense (up $552 thousand), property taxes (up $533 thousand), building depreciation (up $482 thousand), utilities expense (up $304 thousand), depreciation on leasehold improvements (up $242 thousand), expenses related to service contracts (up $293 thousand) and repairs and maintenance expense (up $154 thousand). The increase during the six months ended June 30, 2015 was primarily related to increases in lease expense (up $1.7 million), property taxes (up $942 thousand), building depreciation (up $536 thousand), depreciation on leasehold improvements (up $487 thousand), expenses related to service contracts (up $449 thousand), repairs and maintenance expense (up $310 thousand) and utilities expense (up $218 thousand). The increases in these items were partly related to the additional facilities added in connection with the acquisition of WNB during the second quarter of 2014, a new operations and support center, a portion of which was placed into service during the second quarter of 2015, and new branch locations. We expect higher levels of building depreciation expense related to the new operations and support center in future periods as additional components of the center are placed into service.
Furniture and Equipment. Furniture and equipment expense for the three and six months ended June 30, 2015 increased $442 thousand, or 2.9%, and $1.0 million, or 3.4%, compared to the same periods in 2014. The increases were primarily related to increases in software maintenance (up $654 thousand and $1.5 million during the three and six months ended June 30, 2015, respectively) and depreciation related to furniture and equipment (up $236 thousand and $315 thousand during the three and six months ended June 30, 2015, respectively) partly offset by a decrease in software amortization (down $581 thousand and $886 thousand during the three and six months ended June 30, 2015, respectively).
Deposit Insurance. Deposit insurance expense totaled $3.6 million and $7.2 million for the three and six months ended June 30, 2015 compared to $3.1 million and $6.3 million for the three and six months ended June 30, 2014. The increase in deposit insurance expense for the three and six months ended 2015 compared to the same periods in 2014 was primarily related to an increase in assets, which was partly related to the acquisition of WNB.
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, 2015 increased $66 thousand, or 8.4%, and $271 thousand, or 18.4%, compared to the same periods in 2014. Intangible amortization during the three and six months ended June 30, 2015 was impacted by the additional amortization related to the core deposit intangible recorded in connection with the acquisition of WNB during the second quarter of 2014. The impact of this additional amortization was partly limited by the completion of amortization of certain previously recognized intangible assets as well as a reduction in the annual amortization rate of certain previously recognized intangible assets as we use an accelerated amortization approach which results in higher amortization rates during the earlier years of the useful lives of intangible assets.
Other Non-Interest Expense. Other non-interest expense for the three and six months ended June 30, 2015 decreased $3.0 million, or 6.6%, and $1.6 million, or 1.8%, compared to the same periods in 2014. Other non-interest expense during 2014 was impacted by expenses related to the acquisition of WNB during the second quarter. Acquisition related expenses included in other non-interest expense totaled $4.8 million and $6.0 million during the three and six months ended June 30, 2014, respectively. These costs are included in professional services expenses ($3.2 million during both the three and six months ended June 30, 2014), severance ($1.3 million during both the three and six months ended June 30, 2014) and various other expenses ($425 thousand and $1.5 million during the three and six months ended June 30, 2014, respectively). Excluding these acquisition related expenses during 2014, other non-interest expense for the three and six months ended June 30, 2015 effectively increased $1.8 million, or 4.4%, and $4.4 million, or 5.6%, compared to the same periods in 2014. The effective increase, excluding acquisition related expenses in 2014, for the three months ended June 30, 2015 was partly related to increases in advertising expense (up $926 thousand), guard service expense (up $435 thousand), data communications expense (up $425 thousand), travel/meals and entertainment expense (up $330 thousand) and check card expense (up $289 thousand), among other things. The increases in these items were partly offset by decreases in losses on the sale/write-down of foreclosed assets (down $709 thousand) and donations expense (down $325 thousand). The effective increase, excluding acquisition related expenses in 2014, for the six months ended June 30, 2015 was partly related to increases in check card expense (up $1.1 million), data communications expense (up $868 thousand), advertising expense (up $755 thousand), guard service expense (up $656 thousand), professional expense (up $609 thousand), sundry and other miscellaneous expense (up $575), and travel/meals and entertainment expense (up

$571 thousand), among other things. The increases in these items were partly offset by decreases in in donations expense (down $791 thousand), losses on the sale/write-down of foreclosed assets (down $769 thousand), and postage expense (down $359 thousand).

The increase during the three months ended June 30, 2015 was primarily the result of a $12.7 million increase in net interest income, a $2.0 million decrease in the provision for loan losses, a $1.4 million decrease in income tax expense and a $742 thousand increase in non-interest income partly offset by an $12.0 million increase in non-interest expense. The increase during the six months ended June 30, 2015 was primarily the result of a $33.1 million increase in net interest income, a $6.1 million increase in non-interest income, a $1.2 million decrease in income tax expense and a $488 thousand decrease in the provision for loan losses partly offset by a $24.2 million increase in non-interest expense.

The increase in non-interest income during the six months ended June 30, 2015 was primarily related to increases in other non-interest income; other charges, commissions and fees; insurance commissions and fees; and interchange and debit card transaction fees partly offset by a decrease in service charges on deposit accounts. The increases in other charges, commissions and fees during the three and six months ended June 30, 2015 compared to the same periods in 2014 were primarily related to increases in capital markets fees related to advisory services, letters of credit fees, income from unused balance fees on loan commitments and origination fees collected on loans that did not fund. The increases in insurance commissions and fees during the three and six months ended June 30, 2015 compared to the same periods in 2014 were primarily related to increases in commission income and contingent commissions received from various property and casualty insurance carriers related to the loss performance of insurance policies previously placed. The increases in interchange and debit card transaction fees during the three and six months ended June 30, 2015 compared to the same periods in 2014 were primarily related to increases in income from debit card transactions and ATM service fees. The decrease in other non-interest income for the three months ended June 30, 2015 compared to the same period in 2014 was due to decreases in sundry and other miscellaneous income, income from customer derivative activities and lease rental income partly offset by increases in income from public finance underwriting fees and earnings on life insurance policies. The increase in other non-interest income for the six months ended June 30, 2015 compared to the same period in 2014 was due in part to increases in income from public finance underwriting fees, income from customer derivative activities and earnings on life insurance policies partly offset by a decrease in sundry and other miscellaneous income and lease rental income. The decreases in services charges on deposit accounts for the three and six months ended June 30, 2015 compared to the same periods in 2014 were primarily due to decreases in service charges on commercial

Non-interest expense for the three and six months ended June 30, 2015 increased $12.0 million, or 8.9%, and $24.2 million, or 9.0%, compared to the same periods in 2014. The increase in non-interest expense during the three months ended June 30, 2015 was primarily related to increases in salaries and wages, net occupancy, employee benefits and, to a lesser extent, increases in other non-interest expense, deposit insurance and furniture and fixtures expense. The increase in non-interest expense during the six months ended June 30, 2015 was primarily related to increases in salaries and wages, employee benefits, net occupancy and, to a lesser extent, increases in other non-interest expense, furniture and fixtures expense and deposit insurance. The increases in salaries and wages during the three and six months ended June 30, 2015 compared to the same periods in 2014 were primarily related to an increase in the number of employees, partly related to the acquisition of WNB, and normal annual merit and market increases and, to a lesser extent, increases in stock-based compensation, incentive compensation and overtime. The increases in employee benefits expense during the three and six months ended June 30, 2015 compared to the same periods in 2014 were primarily related to increases in expenses related to our defined benefit retirement plans as well as increases in expenses related to our 401(k) and profit sharing plans, medical insurance expense and payroll taxes.

The increases in these items were partly related to the additional facilities added in connection with the acquisition of WNB during the second quarter of 2014 and a new operations and support center, a portion of which was placed into service during the second quarter of 2015. The increases in other non-interest expense for the three and six months ended June 30, 2015 compared to the same periods in 2014 were primarily related to increases advertising expense, data communications expense, check card expense, guard service expense and travel/meals and entertainment expense. Other non-interest expense during the six months ended June 30, 2015 was also impacted by an increase in sundry and other miscellaneous expenses. These increases in other non-interest expense during the three and six months ended June 30, 2015 were partly offset by decreases in losses on the sale/write-down of foreclosed assets and donations expense. The increases in deposit insurance expense for the three and six months ended June 30, 2015 compared to the same periods in 2014 was primarily related to an increase in assets. The increases in furniture and equipment expense during the three and six months ended June 30, 2015 were primarily related to increases in software maintenance partly offset by decreases in software amortization. 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 $10.1 million and $24.9 million during the three and six months ended June 30, 2015 and $9.8 million and $23.1 million during the three and six months ended June 30, 2014. The increase was primarily related to increases in contingent commissions and commission income. See the analysis of insurance commissions and fees included in the section captioned “Non-Interest Income” included elsewhere in this discussion. Frost Insurance Agency also had consulting revenues totaling $158 thousand and $334 thousand during the three and six months ended June 30, 2015 and $239 thousand and $598 thousand during the three and six months ended June 30, 2014. Consulting revenues are primarily related to human resources consulting services and are reported as a component of other charges, commissions and fees.
Frost Wealth Advisors
Net income for the three and six months ended June 30, 2015 decreased $90 thousand, or 1.7%, and increased $163 thousand, or 1.56%, respectively compared to the same periods in 2014. The decrease during the three months ended June 30, 2015 was primarily due to a $325 thousand increase in non-interest expense partly offset by a $194 thousand increase in net interest income and a $47 thousand decrease in income tax expense. The increase during the six months ended June 30, 2015 was primarily due to a $1.4 million increase in non-interest income and a $336 thousand increase in net interest income partly offset by a $1.5 million increase in non-interest expense and a $90 thousand increase in income tax expense.
Net interest income for the three and six months ended June 30, 2015 increased $194 thousand, or 11.7%, and $336 thousand, or 10.3%, compared to the same periods in 2014. The increase during the three and six months ended June 30, 2015 was primarily due to an increase in the average volume of funds provided due to an increase in the average volume of Frost Wealth Advisors' repurchase agreements and, to a lesser extent, an increase in the funds transfer price received for providing those funds.
Non-interest income did not significantly change for the three months ended June 30, 2015 compared to the same period in 2014 as a $320 thousand decrease in trust and investment management fees was mostly offset by a $252 thousand increase in other charges, commissions and fees and a $61 thousand increase other non-interest income. Non-interest income for the six months ended June 30, 2015 increased $1.4 million, or 2.3%, compared to the same period in 2014. The increase during the six months ended June 30, 2015 was primarily related to an increase in trust and investment management fees. Trust and investment management fee income is the most significant income component for Frost Wealth Advisors. Investment fees are the most

significant component of trust and investment management fees, making up approximately 77.6% of total trust and investment management fees for the first six months of 2015. 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 and investment management fee income during the six months ended June 30, 2015 compared to the same period in 2014 was primarily the result of an increase in trust investment fees and estate fees partly offset by decreases in securities lending income, oil and gas fees and real estate fees. The increase in trust investment fees was primarily due to higher average equity valuations during 2015 and an increase in the number of accounts. Other charges, commissions and fees during the six months ended June 30, 2015 did not significantly fluctuate compared to the same period in 2014 as decreases in income related to the sale of annuities and brokerage commissions were mostly offset by increases in income from the sale of mutual funds and money market accounts. See the analysis of trust and investment management fees included in the section captioned “Non-Interest Income” included elsewhere in this discussion.
Non-interest expense for the three and six months ended June 30, 2015 increased $325 thousand, or 1.4%, and $1.5 million, or 3.1%, compared to the same periods in 2014. The increase in non-interest expense during the three months ended June 30, 2015 was primarily related to increases in salaries and wages (up $623 thousand) and employee benefits (up $161 thousand) partly offset by a decrease in other non-interest expense (down $475 thousand). The increase in non-interest expense during the six months ended June 30, 2015 was primarily related to increases in salaries and wages (up $839 thousand), other non-interest expense (up $332 thousand) and employee benefits (up $257 thousand). The increases in salaries and wages during the three and six months ended June 30, 2015 were primarily related to normal annual merit and market increases and, to a lesser extent, increases in incentive compensation and stock-based compensation. The increases in employee benefits during the three and six months ended June 30, 2015 were partly due to increases in expenses related to our defined benefit retirement plans, 401(k) and profit sharing plans and payroll taxes, among other things. The variation in other non-interest expense during the three and six months ended June 30, 2015 was related to fluctuations in various miscellaneous categories of expense and overhead cost allocations.
Non-Banks
The Non-Banks operating segment had net losses of $1.2 million and $2.1 million for the three and six months ended June 30, 2015, respectively, compared to net losses of $2.8 million and $2.7 million for the same periods in 2014. The decrease in the net loss for the three months ended June 30, 2015 was primarily due to a $3.0 million decrease in other non-interest expense partly offset by a $946 thousand decrease in other non-interest income and a $458 thousand decrease in the net income tax benefit. The decrease in net loss during the six months ended June 30, 2015 was primarily due to a $2.9 million decrease in other non-interest expense partly offset by a $2.0 million decrease in other non-interest income.
Other non-interest expense during 2014 included approximately $3.0 million of expenses associated with the acquisition of WNB during the second quarter. This amount was primarily related to professional services. The decreases in other non-interest income during the three and six months ended June 30, 2015 were primarily related to decreases in mineral interest income. Mineral interest income is related to bonus, rental and shut-in payments and oil and gas royalties received from severed mineral interests on property owned by our wholly-owned non-banking subsidiary Main Plaza Corporation. The decrease in mineral interest income was partly related to lower energy prices and a decrease in production.
Income Taxes
We recognized income tax expense of $12.6 million and $24.7 million, for an effective tax rate of 14.7% and 14.5% for the three and six months ended June 30, 2015 compared to $13.5 million and $25.6 million, for an effective tax rate of 16.9% and 16.7% for the three and six months ended June 30, 2014. 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 the three and six months ended June 30, 2015 was partly related to an increase in the relative proportion of tax-exempt income as we purchased additional tax-exempt municipal securities.

Average Balance Sheet
Average assets totaled $27.8 billion for the six months ended June 30, 2015 representing an increase of $3.4 billion, or 13.9%, compared to average assets for the same period in 2014. The growth in average assets was primarily funded by an increase in average deposits. Average assets during the six months ended June 30, 2015 were also partly impacted by the acquisition of WNB on May 30, 2014. See Note 2 - Mergers and Acquisitions in the accompanying consolidated financial statements included elsewhere in this report for additional information related to this acquisition. The increase in average assets was primarily reflected in earning assets, which increased $3.1 billion, or 13.6%, during the first six months of 2015 compared to the same period of 2014. The increase in earning assets was primarily due to a $2.8 billion increase in average securities and a $1.3 billion increase in average loans partly offset by $1.0 billion decrease in average interest-bearing deposits. We acquired cash and cash equivalents totaling $879.7 million, loans totaling $670.6 million and securities totaling $154.2 million in connection with the acquisition of WNB. Total deposits averaged $23.8 billion for the first six months of 2015, increasing $2.9 billion, or 14.1%, compared to the same period in 2014. We acquired $1.6 billion of deposits in connection with the acquisition of WNB. Average interest-bearing deposit accounts totaled 58.2% and 59.5% of average total deposits during the first six months of 2015 and 2014, respectively.

Loans increased $413.3 million, or 3.8%, compared to December 31, 2014. The majority of our loan portfolio is comprised of commercial and industrial loans and real estate loans. Commercial and industrial loans made up 52.3% and 52.5% of total loans at June 30, 2015 and December 31, 2014, respectively, while real estate loans made up 44.4% and 44.1% of total loans, respectively, at those dates. Real estate loans include both commercial and consumer balances.
Commercial and industrial loans increased $198.2 million, or 3.4%, during the first six months of 2015. Our 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 our loan policy guidelines. The commercial and industrial loan portfolio also includes commercial leases and 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 our originated portfolio. Our purchased SNC portfolio totaled $793.1 million at June 30, 2015, increasing $55.0 million, or 7.5%, from $738.2 million at December 31, 2014. At June 30, 2015, 59.5% of outstanding purchased SNCs were related to the energy industry and 11.4% of outstanding purchased SNCs were related to the construction 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 our customers. As a matter of policy, we generally only participate in SNCs for companies headquartered in or which have significant operations within our market areas. In addition, we 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 increased $206.2 million, or 4.3%, during the first six months of 2015. Real estate loans include both commercial and consumer balances. Commercial real estate loans totaled $4.2 billion at June 30, 2015 and represented 82.8% of total real estate loans. The majority of this portfolio consists of commercial real estate mortgages, which includes both permanent and intermediate term loans. Our primary focus for the 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 and consumer installment loans, totaled $1.3 billion at June 30, 2015 and $1.2 billion at December 31, 2014. Consumer real estate loans, increased $18.6 million, or 2.2%, from December 31, 2014. Combined, home equity loans and lines of credit made up 64.9% and 66.3% of the consumer real estate loan total at June 30, 2015 and December 31, 2014, respectively. We offer 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, we do not originate 1-4 family mortgage loans; however, from time to time, we may invest in such loans to meet the needs of our customers. Consumer installment loans, increased $9.6 million, or 2.5%, from December 31, 2014. 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 include non-accrual loans, troubled debt restructurings and foreclosed assets. Non-performing assets at June 30, 2015 decreased $12.7 million from December 31, 2014. Non-accrual commercial and industrial loans included one credit relationship in excess of $5 million as of June 30, 2015 and December 31, 2014. This credit relationship totaled $15.2 million at June 30, 2015 and $15.5 million at December 31, 2014. 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. One credit relationship totaling $5.6 million at December 31, 2014 was included in both non-accrual commercial and industrial loans ($2.7 million) and non-accrual commercial real estate loans ($2.9 million).
Generally, loans are placed on non-accrual status if principal or interest payments become 90 days past due and/or management deems the collectibility 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. Classification of a loan as non-accrual does not preclude the ultimate collection of loan principal or interest.
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. Regulatory guidelines require us to reevaluate the fair value of foreclosed assets on at least an annual basis. Our policy is to comply with the regulatory guidelines. 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. Write-downs of foreclosed assets totaled $36 thousand and $994 thousand, during the six months ended June 30, 2015 and 2014, respectively. 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, 2015 and December 31, 2014, we had $111.8 million and $15.1 million in loans of this type which are not included in any one of the non-accrual, restructured or 90 days past due loan categories. At June 30, 2015, potential problem loans consisted of 10 credit relationships. Of the total outstanding balance at June 30, 2015, 51.5% related to four customers in the energy industry, 23.2% related to two customers in manufacturing and 19.5% related to two customers in real estate. Weakness in these organizations’ operating performance, financial condition and borrowing base deficits for certain energy credits, among other factors, have caused us to heighten the attention given to these credits. As such, all of the loans identified as potential problem loans at June 30, 2015 were graded as either "special mention" (risk grade 10) or "substandard - accrual" (risk grade 11), with a weighted-average risk grade of 10.8. Potential problem loans impact the allocation of our allowance for loan losses as a result of our risk grade based allocation methodology. See Note 4 - Loans in the accompanying consolidated financial statements for details regarding our allowance allocation methodology.
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. Our 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. Our 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 4 - Loans in the accompanying notes to consolidated financial statements included elsewhere in this report for further details regarding our 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:

The reserve allocated to commercial and industrial loans at June 30, 2015 increased $9.5 million compared to December 31, 2014. This increase was primarily related to increases in historical valuation allowances, the environmental risk adjustment, reserves allocated for excessive industry concentrations and highly leveraged credit relationships and a decrease in the adjustment for recoveries partly offset by decreases in reserves allocated for general macroeconomic risk, credit and collateral exceptions and distressed industries. Historical valuation allowances increased $8.6 million from $32.4 million at December 31, 2014 to $41.0 million at June 30, 2015. The increase in historical valuation allowances was due to an increase in the volume of classified commercial and industrial loans, particularly those graded as substandard (risk grade 11) and an increase in the volume of non-classified commercial and industrial loans, particularly those graded as special mention (risk grade 10) and watch (risk grade 9). Classified commercial and industrial loans (loans having a risk grade of 11, 12 or 13) totaled $152.1 million at June 30, 2015 compared to $95.0 million at December 31, 2014. Non-classified commercial and industrial loans graded as special mention and watch (risk grades 9 and 10) totaled $251.8 million at June 30, 2015 compared to $147.2 million at December 31, 2014. Historical valuation allowances were also partly impacted by a change in our allocation methodology related to credit and collateral exceptions, as further discussed below. The impact of the aforementioned volume increases and methodology change was partly offset by decreases in the historical loss allocation factors applied to certain categories of non-classified and classified commercial and industrial loans. The environmental risk adjustment increased $898 thousand from $6.8 million at December 31, 2014 to $7.7 million at June 30, 2015. Although the environmental adjustment factor has decreased slightly from December 31, 2014, the dollar amount of the environmental risk adjustment increased as a result of the aforementioned increase in the historical valuation allowances to which the environmental adjustment factor is applied. The reserve allocated for excessive industry concentrations

61

Table of Contents

increased $4.0 million from $2.1 million at December 31, 2014 to $6.2 million at June 30, 2015 primarily due to increased risk concentrations related to energy production and energy service credits. The weighted average risk-grade for energy loans was 6.39 at June 30, 2015 compared to 5.45 at December 31, 2014. The reserves allocated for highly leveraged credit relationships increased $1.8 million from $4.0 million at December 31, 2014 to $5.7 million at June 30, 2015 primarily due to an increase in the volume of such credit relationships, which were mostly pass-grade, energy and non-energy related commercial and industrial loans with commitments in excess of $10.0 million. The adjustment for recoveries decreased $2.3 million from $6.2 million at December 31, 2014 to $4.0 million at June 30, 2015 primarily due to the lower level of recoveries, on an annualized basis, experienced in the first six months of 2015 relative to adjusted annual recoveries for 2014. The reserve allocated for general macroeconomic risk totaled $587 thousand at June 30, 2015 compared to $7.7 million at December 31, 2014. At December 31, 2014, the level of the reserve for general macroeconomic risk reflected the prevailing market conditions, particularly the uncertainty associated with decreasing oil prices. The decrease in the reserve allocated for general macroeconomic risk resulted as the risks associated with decreased oil prices are now reflected in other components of the overall reserves allocated for commercial and industrial loans, primarily the aforementioned increases in historical valuation allowances and allocations for excessive industry concentrations. The reserve allocated to energy loans within our commercial and industrial loan portfolio, excluding the impact of the reserve for general macroeconomic risk, increased $14.9 million from $11.1 million at December 31, 2014 to $26.0 million at June 30, 2015. The reserve allocated to other categories of loans within our commercial and industrial loan portfolio segment, excluding the impact of the reserve for general macroeconomic risk, increased $1.7 million from $40.4 million at December 31, 2014 to $42.1 million at June 30, 2015. As discussed in Note 4 - Loans in the accompanying consolidated financial statements, beginning in the second quarter of 2015, reserves allocated for credit and collateral exceptions are captured within our loan risk grade matrix and are a component of our historical valuation allowances. Accordingly, there were no general valuation allowance allocations for credit and collateral exceptions at June 30, 2015, while such allocations totaled $1.5 million at December 31, 2014. The distressed industries allocation for commercial and industrial loans decreased $783 thousand from $3.1 million at December 31, 2014 to $2.3 million at June 30, 2015. The decrease was primarily related to improvements in the weighted-average risk grades of certain segments of the contractors industry to a level below that of the weighted-average risk grade for all pass-grade loans within the overall loan portfolio segment. As a result, additional distressed industry allocations were no longer necessary for these segments of the contractors industry.
The reserve allocated to commercial real estate loans at June 30, 2015 decreased $2.2 million compared to December 31, 2014. The decrease was primarily related to decreases in reserves allocated for general macroeconomic risk and credit and collateral exceptions partly offset by a decrease in the adjustment for recoveries combined with increases in historical valuation allowances and reserves allocated for distressed industries, large relationship concentrations and highly leveraged credit relationships. The reserve allocated for general macroeconomic risk totaled $213 thousand at June 30, 2015 compared to $3.5 million at December 31, 2014. The decrease reflects, in part, positive trends related to commercial real estate loan charge-offs and classified commercial real estate loans. Net commercial real estate loan charge-offs totaled $12 thousand during the first six months of 2015 compared to $1.7 million during the first six months of 2014. Classified commercial real estate loans totaled $62.8 million at June 30, 2015 compared to $65.8 million at December 31, 2014. As mentioned above, reserves allocated for credit and collateral exceptions are now captured within our loan risk grade matrix and are a component of our historical valuation allowances. Accordingly, there were no general valuation allowance allocations for credit and collateral exceptions at June 30, 2015, while such allocations totaled $681 thousand at December 31, 2014. The adjustment for recoveries decreased $861 thousand from $1.8 million at December 31, 2014 to $939 thousand at June 30, 2015 primarily due to the lower level of recoveries, on an annualized basis, experienced in the first six months of 2015 relative to adjusted annual recoveries for 2014. Historical valuation allowances increased $426 thousand from $14.7 million at December 31, 2014 to $15.1 million at June 30, 2015. The increase in historical valuation allowances was due to an increase in the volume of non-classified commercial and industrial loans, particularly those graded as watch (risk grade 9) and special mention (risk grade 10). Non-classified commercial real estate loans graded as watch and special mention totaled $266.2 million at June 30, 2015 compared to $170.1 million at December 31, 2014. Historical valuation allowances were also partly impacted by a change in our allocation methodology related to credit and collateral exceptions, as discussed above. The distressed industries allocation related to commercial real estate loans increased $263 thousand while reserves allocated for large credit relationships and highly leveraged credit relationships increased $166 thousand and $108 thousand, respectively, from December 31, 2014 to June 30, 2015 primarily due to increases in the volumes of such credit relationships.
The reserve allocated to consumer real estate loans at June 30, 2015 decreased $476 thousand compared to December 31, 2014. This decrease was primarily due to a decrease in the reserve for general macroeconomic risk partly offset by increases in the allocation for loans not reviewed by concurrence and historical valuation allowances and a decrease in the adjustment for recoveries.
The reserve allocated to consumer and other loans at June 30, 2015 increased $236 thousand compared to December 31, 2014. The increase was primarily related to an increase in the historical valuation allowances due to an increase in the historical loss allocation factor applied to consumer and other loans and an increase in the volume of such loans combined with an increase in the environmental risk adjustment. These increases were partly offset by decreases in the reserve allocated for general macroeconomic risk and an increase in the adjustment for recoveries.

The provision for loan losses decreased $489 thousand, or 4.2%, during the six months ended June 30, 2015 compared to the same period in 2014. Despite an increase in the weighted-average risk grade of our commercial and industrial and commercial real estate loan portfolios, the level of the provision for loan losses decreased during 2015 primarily due to decreases in the level of net charge-offs and the volume of non-performing loans. The overall weighted-average risk grade of our commercial and industrial and commercial real estate portfolios was 6.50 at June 30, 2015 compared to 6.29 at December 31, 2014. The increase in the weighted-average risk grade of our commercial and industrial and commercial real estate loan portfolios was primarily driven by the upward migration of risk grades within our energy loan portfolio as detailed above. This upward risk grade migration in our energy loan portfolio resulted in higher historical valuation allowances and increases in the various categories of general valuation allowances that are based upon our loan risk-grade matrix, particularly the reserves allocated for excessive industry concentrations. In consideration of the prevailing market conditions, particularly the uncertainty associated with decreasing oil prices during the latter part of 2014, we had previously anticipated increasing risk grades within our loan portfolio, particularly the energy loans. As a result, we maintained higher reserves for general macroeconomic risk as of December 31, 2014. Though uncertainty associated with oil price volatility continues to be a factor as of June 30, 2015, we believe we have identified the significant credit risks within our energy loan portfolio as well as other associated risks impacting the rest of our loan portfolio and captured those risks within our loan risk grade matrix and our allowance allocation methodology, as detailed above. In light of this, along with improving conditions in other areas of the economy and unemployment, as reflected in the recent upward movement of the Texas Leading Index which totaled totaled 127.1 at May 31, 2015 increasing from a recent low of 125.2 at March 31, 2015 but still down from 129.4 at December 31, 2014, higher levels of reserves for general macroeconomic risk were not considered necessary at June 30, 2015. As increases in historical valuation allowances and other components of our general valuation allowances offset the decrease in reserves for general macroeconomic risk, the level of the provision for loan losses was not significantly impacted during the first six months of 2015 beyond the level required to compensate for overall loan growth and net charge-offs during the period. The ratio of the allowance for loan losses to total loans was 0.94% at June 30, 2015 compared to 0.91% at December 31, 2014. 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, as described, in part, herein. Should any of the factors considered by management in evaluating the appropriate level of the allowance for loan losses change, our 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 $2.9 billion at both June 30, 2015 and December 31, 2014. In addition to net income of $145.2 million, other sources of capital during the six months ended June 30, 2015 included $9.0 million in proceeds from stock option exercises and related tax benefits of $750 thousand and $5.3 million related to stock-based compensation. Uses of capital during the six months ended June 30, 2015 included $69.9 million of dividends paid on preferred and common stock, other comprehensive loss, net of tax, of $59.5 million and $10.6 million of treasury stock purchases.
The accumulated other comprehensive income/loss component of shareholders’ equity totaled a net, after-tax, unrealized gain of $82.3 million at June 30, 2015 compared to a net, after-tax, unrealized gain of $141.8 million at December 31, 2014. The decrease was primarily due to a $51.3 million net after-tax decrease in the net unrealized gain on securities available for sale and a $10.5 million net after-tax decrease in the net unrealized gain on securities transferred to held to maturity partly offset by a $2.3 million net after-tax decrease in the net actuarial loss of our defined benefit post-retirement benefit plans.
The Basel III Capital Rules became effective for Cullen/Frost and Frost Bank on January 1, 2015 (subject to a phase-in period for certain provisions). In connection with the adoption of the Basel III Capital Rules, we elected to opt-out of the requirement to include most components of accumulated other comprehensive income in regulatory capital. Accordingly, 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 capital and take into consideration the risk inherent in both on-balance sheet and off-balance sheet items. See Note 8 - Capital and Regulatory Matters in the accompanying notes to consolidated financial statements included elsewhere in this report.
We paid quarterly dividends of $0.51 and $0.53 per common share during the first and second quarters of 2015 and quarterly dividends of $0.50 and $0.51 per common share during the first and second quarters of 2014. This equates to a common stock dividend payout ratio of 46.0% and 47.3% during the first and second quarters of 2015 and 51.5% and 49.7% during the first and second quarters of 2014, respectively. Under the terms of the junior subordinated deferrable interest debentures that we issued to Cullen/Frost Capital Trust II and WNB Capital Trust I, we have the right at any time during the term of the debentures to defer the payment of interest at any time or from time to time for an extension period not exceeding 20 consecutive quarterly periods with respect to each extension period. Our ability to declare or pay dividends on, or purchase, redeem or otherwise acquire, shares of our capital stock is subject to certain restrictions during any such extension period.
Under the terms of our Series A Preferred Stock, our ability to declare or pay dividends on, or purchase, redeem or otherwise acquire, shares of our common stock or any of our securities that rank junior to our Series A Preferred Stock is subject to certain restrictions in the event that we do not declare and pay dividends on our Series A Preferred Stock for the most recent dividend period.
Stock Repurchase Plans. From time to time, our board of directors has authorized stock repurchase plans. In general, stock repurchase plans allow us to proactively manage our capital position and return excess capital to shareholders. Shares purchased under such plans also provide us with shares of common stock necessary to satisfy obligations related to stock compensation awards. On April 30, 2015, our board of directors authorized a $100.0 million stock repurchase program, allowing us to repurchase shares of our common stock over a two-year period from time to time at various prices in the open market or through private transactions. Under the plan, we repurchased 140,571 shares at a total cost of $10.6 million during the six months ended June 30, 2015. 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 objective of our liquidity management is to manage cash flow and liquidity reserves so that they are adequate to fund our operations and to meet obligations and other commitments on a timely basis and at a reasonable cost. We seek to achieve this objective and ensure that funding needs are met by maintaining an appropriate level of liquid funds through asset/liability management, which includes managing the mix and time to maturity of financial assets and financial liabilities on our balance sheet. Our liquidity position is enhanced by our ability to raise additional funds as needed in the wholesale markets.
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.

Table of Contents

Liability liquidity is provided by access to funding sources which include core deposits and correspondent banks in our 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.
Our liquidity position is continuously monitored and adjustments are made to the balance between sources and uses of funds as deemed appropriate. Liquidity risk management is an important element in our asset/liability management process. We regularly model liquidity stress scenarios to assess potential liquidity outflows or funding problems resulting from economic disruptions, volatility in the financial markets, unexpected credit events or other significant occurrences deemed problematic by management. These scenarios are incorporated into our contingency funding plan, which provides the basis for the identification of our liquidity needs. As of June 30, 2015, management is not aware of any events that are reasonably likely to have a material adverse effect on our liquidity, capital resources or operations. In addition, management is not aware of any regulatory recommendations regarding liquidity, that would have a material adverse effect on us.
Since Cullen/Frost is a holding company and does not conduct operations, our 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 8 - Capital and Regulatory Matters in the accompanying notes to consolidated financial statements included elsewhere in this report regarding such dividends. At June 30, 2015, Cullen/Frost had liquid assets, including cash and resell agreements, totaling $284.9 million.

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 2014 Form 10-K. There has been no significant change in the types of market risks we face since December 31, 2014.
We utilize 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 flat-rate 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.
For modeling purposes, as of June 30, 2015, the model simulations projected that a 100 basis point ratable increase in interest rates would result in a negative variance in net interest income of 0.1% and a 200 basis point ratable increase in interest rates would result in a positive variance in net interest income of 0.3%, relative to the flat-rate 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 3.0% relative to the flat-rate case over the next 12 months. The June 30, 2015 model simulations were impacted by the assumption, for modeling purposes, that we will begin to pay interest on demand deposits (those not already receiving an earnings credit rate) in the third quarter of 2015, as further discussed below. As of June 30, 2014, the model simulations projected that 100 and 200 basis point ratable increases in interest rates would result in positive variances in net interest income of 0.4% and 1.3%, respectively, relative to the flat-rate 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 3.2% relative to the flat-rate case over the next 12 months. The June 30, 2014 model simulations were impacted by the assumption, for modeling purposes, that we would begin to pay interest on demand deposits in the third quarter of 2014. The likelihood of a decrease in interest rates beyond 25 basis points as of June 30, 2015 and 2014 was considered to be remote given prevailing interest rate levels.
The model simulations as of June 30, 2015 indicate that our balance sheet is less asset sensitive in comparison to our balance sheet as of June 30, 2014. The decrease in asset sensitivity is primarily due to an increase in the relative proportion of interest-earning assets invested in fixed-rate securities and a decrease in the relative proportion of interest-earning assets invested in variable-rate interest-bearing deposits, which generally reprice as market interest rates change. The growth in our balance sheet since June 30, 2014 was primarily funded by deposit growth.
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 prohibition 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. To date, we have not experienced any significant additional interest costs as a result of the repeal; however, we may begin to incur interest costs associated with certain demand deposits in the future as market conditions warrant. If this were to occur, our balance sheet would likely become more 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 our control, we assumed an aggressive pricing structure for the purposes of the model simulations discussed above with interest payments beginning in the third quarter of 2015. 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 demand deposits become an administered rate with less direct correlation to movements in general market interest rates, our balance sheet could be more asset sensitive than the model simulations might otherwise indicate.
As of June 30, 2015, the effects of a 200 basis point increase and a 25 basis point decrease in interest rates on our derivative holdings would not result in a significant variance in our net interest income.
The effects of hypothetical fluctuations in interest rates on our 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.
