Note 1 - Significant Accounting Policies
Nature of Operations. Cullen/Frost Bankers, Inc. (“Cullen/Frost”) is a financial holding company and a bank holding company headquartered in San Antonio, Texas that provides, through its subsidiaries, a broad array of products and services throughout numerous Texas markets. The terms “Cullen/Frost,” “the Corporation,” “we,” “us” and “our” mean Cullen/Frost Bankers, Inc. and its subsidiaries, when appropriate. In addition to general commercial and consumer banking, other products and services offered include trust and investment management, insurance, brokerage, mutual funds, 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, 2021, included in our Annual Report on Form 10-K filed with the SEC on February 4, 2022 (the “2021 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:

As of March 31,June 30, 2022, no allowance for credit losses has been recognized on available for sale securities in an unrealized loss position as management does not believe any of the securities are impaired due to reasons of credit quality. This is based upon our analysis of the underlying risk characteristics, including credit ratings, and other qualitative factors related to our available for sale securities and in consideration of our historical credit loss experience and internal forecasts. The issuers of these securities continue to make timely principal and interest payments under the contractual terms of the securities. Furthermore, 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. The unrealized losses

Table of Contents
unrealized losses are 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 securities approach their maturity date or repricing date or if market yields for such investments decline.
Contractual Maturities. The following table summarizes the maturity distribution schedule of securities held to maturity and securities available for sale as of March 31,June 30, 2022. Mortgage-backed securities are included in maturity categories based on their stated maturity date. Expected maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations. Other securities classified as available for sale include stock in the Federal Reserve Bank and the Federal Home Loan Bank, which have no maturity date. These securities have been included in the total column only.

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, (iv) non-performing loans (see details above) and (vi)(v) 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 set forth in our 2021 Form 10-K. We monitor portfolio credit quality by the weighted-average risk grade of each class of commercial loan. Individual relationship managers, under the oversight of credit administration, review updated financial information for all pass grade loans to reassess the risk grade on at least an annual basis. When a loan has a 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 risk grade of 10 or higher, a special assets officer monitors the loan on an on-going basis.

Allowance For Credit Losses - Loans. The allowance for credit losses on loans is a contra-asset valuation account, calculated in accordance with ASC 326, that is deducted from the amortized cost basis of loans to present the net amount expected to be collected. The amount of the allowance represents management's best estimate of current expected credit losses on loans considering available information, from internal and external sources, relevant to assessing collectibility over the loans' contractual terms, adjusted for expected prepayments when appropriate. Credit loss expense related to loans reflects the totality of actions taken on all loans for a particular period including any necessary increases or decreases in the allowance related to changes in credit loss expectations associated with specific loans or pools of loans. 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 appropriateness of the allowance is dependent upon a variety of factors beyond our control, including the performance of our loan portfolio, the economy, changes in interest rates and the view of the regulatory authorities toward loan classifications. Our allowance methodology is more fully described in our 2021 Form 10-K.

Note 6 - Off-Balance-Sheet Arrangements, Commitments, Guarantees 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. As more fully discussed in our 2021 Form 10-K, 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.
Financial instruments with off-balance-sheet risk were as follows:

Allowance For Credit Losses - Off-Balance-Sheet Credit Exposures. The allowance for credit losses on off-balance-sheet credit exposures is a liability account, calculated in accordance with ASC 326, representing expected credit losses over the contractual period for which we are exposed to credit risk resulting from a contractual obligation to extend credit. No allowance is recognized if we have the unconditional right to cancel the obligation. Off-balance-sheet credit exposures primarily consist of amounts available under outstanding lines of credit and letters of credit detailed in the table above. The amount of the allowance represents management's best estimate of expected credit losses on commitments expected to be funded over the contractual life of the commitment. Our allowance methodology is more fully described in our 2021 Form 10-K.
The following table details activity in the allowance for credit losses on off-balance-sheet credit exposures.

Note 7 - 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.
Cullen/Frost’s and Frost Bank’s Common Equity Tier 1 capital (“CET1”) includes 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 CET1. We also elected to exclude the effects of credit loss accounting under CECL from CET1 for a five-year transitional period, as further discussed in our 2021 Form 10-K. This CECL transitional adjustment totaled $46.2 million and $61.6 million at March 31,June 30, 2022 and December 31, 2021, respectively. CET1 is reduced by goodwill and other intangible assets, net of associated deferred tax liabilities. Frost Bank's CET1 is also reduced by its equity investment in its financial subsidiary, Frost Insurance Agency (“FIA”).
Tier 1 capital includes CET1 and additional Tier 1 capital. For Cullen/Frost, additional Tier 1 capital included $145.5 million of 4.450% non-cumulative perpetual preferred stock at March 31,June 30, 2022 and December 31, 2021, the details of which are further discussed below. Frost Bank did 0t have any additional Tier 1 capital beyond Common Equity Tier 1 at March 31,June 30, 2022 or December 31, 2021. 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 allowances for credit losses on securities, loans and off-balance-sheet credit exposures. Tier 2 capital for Cullen/Frost also includes the permissible portion of qualified subordinated debt (which decreases 20.0% per year during the final five years of the term of the notes) totaling $80.0 million at March 31,June 30, 2022 and $100.0 million at December 31, 2021 and trust preferred securities totaling $120.0 million at both March 31,June 30, 2022 and December 31, 2021.

As of March 31,June 30, 2022, capital levels at Cullen/Frost and Frost Bank exceed all capital adequacy requirements under the Basel III Capital Rules. Based on the ratios presented above, capital levels as of March 31,June 30, 2022 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 Board 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 March 31,June 30, 2022, that Cullen/Frost and Frost Bank meet all capital adequacy requirements to which they are subject.
Preferred Stock. Outstanding preferred stock includes 150,000 shares, or $150.0 million in aggregate liquidation preference, of our 4.450% Non-Cumulative Perpetual Preferred Stock, Series B, par value $0.01 and liquidation preference $1,000 per share (“Series B Preferred Stock”). Each share of Series B Preferred Stock issued and outstanding is represented by 40 depositary shares, each representing a 1/40th ownership interest in a share of the Series B Preferred Stock (equivalent to a liquidation preference of $25 per share). The Series B Preferred Stock qualifies as Tier 1 capital for the purposes of the regulatory capital calculations. The net proceeds from the issuance and sale of the Series B Preferred Stock, after deducting $4.5 million of issuance costs including the underwriting discount and professional service fees, among other things, were approximately $145.5 million. Refer to our 2021 Form 10-K for additional details related to our Series B Preferred Stock.
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 January 26, 2022, our board of directors authorized a $100.0 million stock repurchase program, allowing us to repurchase shares of our common stock over a one-year period from time to time at various prices in the open market or
22

through private transactions. No shares have been repurchased under this plan or the prior plan during the reported periods. Under the Basel III Capital Rules, Cullen/Frost may not repurchase or redeem any of its preferred stock or subordinated notes and, in some cases, its common stock without the prior approval of the Federal Reserve Board.
Dividend Restrictions. In the ordinary course of business, Cullen/Frost is dependent upon dividends from Frost Bank to provide funds for the payment of dividends to shareholders and to provide for other cash requirements, including to repurchase its common stock. 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 March 31,June 30, 2022, Frost Bank could pay aggregate dividends of up to $325.0$447.3 million to Cullen/Frost without prior regulatory approval.
Under the terms of the junior subordinated deferrable interest debentures that Cullen/Frost has issued to Cullen/Frost Capital Trust II, Cullen/Frost has 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.
Note 8 - Derivative Financial Instruments
The fair value of derivative positions outstanding is included in accrued interest receivable and other assets and accrued interest payable and other liabilities in the accompanying consolidated balance sheets and in the net change in each of these financial statement line items in the accompanying consolidated statements of cash flows.
Interest Rate Derivatives. We utilize interest rate swaps, caps, swaptions and floors to mitigate exposure to interest rate risk and to facilitate the needs of our customers. Our objectives for utilizing these derivative instruments are described in our 2021 Form 10-K.
The notional amounts and estimated fair values of interest rate derivative contracts are presented in the following table. The fair values of interest rate derivative contracts are estimated utilizing internal valuation methods with observable market data inputs, or as determined by the Chicago Mercantile Exchange (“CME”) for centrally cleared derivative contracts. CME rules legally characterize variation margin payments for centrally cleared derivatives as settlements of the derivatives' exposure rather than collateral. As a result, the variation margin payment and the related derivative instruments are considered a single unit of account for accounting and financial reporting purposes. Variation margin, as determined by the CME, is settled daily. As a result, derivative contracts that clear through the CME have an estimated fair value of zero as of March 31,June 30, 2022 and December 31, 2021.

Commodity Derivatives. We enter into commodity swaps and option contracts that are not designated as hedging instruments primarily to accommodate the business needs of our customers. Upon the origination of a commodity swap or option contract with a customer, we simultaneously enter into an offsetting contract with a third party financial institution to mitigate the exposure to fluctuations in commodity prices.
The notional amounts and estimated fair values of non-hedging commodity swap and option derivative positions outstanding are presented in the following table. We obtain dealer quotations and use internal valuation methods with observable market data inputs to value our commodity derivative positions.

Foreign Currency Derivatives. We enter into foreign currency forward and option 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 and options that are not designated as hedging instruments to mitigate the economic effect of fluctuations in foreign currency

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 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.

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. Our credit exposure relating to interest rate swaps, commodity swaps/options and foreign currency forward and option contracts with bank customers was approximately $238.4$198.1 million at March 31,June 30, 2022. 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 forwardforward/option contracts with upstream financial institution counterparties was approximately $35.7$41.5 million at March 31,June 30, 2022. This amount was primarily related to initial margin payments to the CME and excess collateral we

posted to counterparties. Excess collateral is generally cleared on the next business day. Collateral levels for upstream financial institution counterparties are monitored and adjusted as necessary. See Note 9 – Balance Sheet Offsetting and Repurchase Agreements for additional information regarding our credit exposure with upstream financial institution counterparties. At March 31,June 30, 2022, we had $247.3$212.4 million in cash collateral related to derivative contracts on deposit with other financial institution counterparties.

Note 9 - 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 March 31,June 30, 2022 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 March 31,June 30, 2022 and December 31, 2021 is presented in the following tables.

Stock-based compensation expense is recognized ratably over the requisite service period for all awards. For most stock option awards, the service period generally matches the vesting period. For stock options granted to certain executive officers and for non-vested stock units granted to all participants, the service period does not extend past the date the participant reaches 65 years of age. Deferred stock units granted to non-employee directors generally have immediate vesting and the related expense is fully recognized on the date of grant. For performance stock units, the service period generally matches the three-year performance period specified by the award, however, the service period does not extend past the date the participant reaches 65 years of age. Expense recognized each period is dependent upon our estimate of the number of shares that will ultimately be issued.
Stock-based compensation expense or benefit and the related income tax benefit is presented in the following table. The service period for performance stock units granted each year begins on January 1 of the following year.

We had a net deferred tax asset totaling $110.3$245.9 million at March 31,June 30, 2022 and a net deferred tax liability totaling $81.2 million at December 31, 2021. No valuation allowance for deferred tax assets was recorded at March 31,June 30, 2022 as management believes it is more likely than not that all of the deferred tax assets will be realized against deferred tax liabilities and projected future taxable income.
The effective income tax rates differed from the U.S. statutory federal income tax rates of 21% during the comparable periods primarily due to the effect of tax-exempt income from loans, securities and life insurance policies and the income tax effects associated with stock-based compensation. There were no unrecognized tax benefits during any of the reported periods.

Table of Contents
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 2018.
Note 14 - 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. Reclassification adjustments related to defined-benefit post-retirement benefit plans are included in the computation of net periodic pension expense (see Note 12 – Defined Benefit Plans).

Note 16 – 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 three-level 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. See our 2021 Form 10-K for additional information regarding the fair value hierarchy and a description of our valuation techniques.
Financial Assets and Financial Liabilities. The tables below summarize financial assets and financial liabilities measured at fair value on a recurring basis as of March 31,June 30, 2022 and December 31, 2021, segregated by the level of the valuation inputs within the fair value hierarchy of ASC Topic 820 utilized to measure fair value.

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. Financial assets measured at fair value on a non-recurring basis during the reported periods include certain collateral dependent loans reported at the fair value of the underlying collateral if repayment is expected solely from the collateral.
The following table presents collateral dependent loans that were remeasured and reported at fair value through a specific allocation of the allowance for credit losses on loans 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. From time to time, non-financial assets measured at fair value on a non-recurring basis may 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. There were no such fair value measurements during the reported periods.
Financial Instruments Reported at Amortized Cost. The estimated fair values of financial instruments that are reported at amortized cost in our consolidated balance sheets, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value, were as follows:

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 17 - Accounting Standards Updates
Information about certain recently issued accounting standards updates is presented below. Also refer to Note 20 - Accounting Standards Updates in our 2021 Form 10-K for additional information related to previously issued accounting standards updates.
ASU 2022-01, “Derivatives and Hedging (Topic 815): Fair Value Hedging - Portfolio Layer Method.” Under prior guidance, entities can apply the last-of-layer hedging method to hedge the exposure of a closed portfolio of prepayable financial assets to fair value changes due to changes in interest rates for a portion of the portfolio that is not expected to be affected by prepayments, defaults, and other events affecting the timing and amount of cash flows. ASU 2022-01 expands the last-of-layer method, which permits only one hedge layer, to allow multiple hedged layers of a single closed portfolio. To reflect that expansion, the last-of-layer method is renamed the portfolio layer method. ASU 2022-01 also (i) expands the scope of the portfolio layer method to include non-prepayable financial assets, (ii) specifies eligible hedging instruments in a single-layer hedge, (iii) provides additional guidance on the accounting for and disclosure of hedge basis adjustments under the portfolio layer method and (iv) specifies how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio. ASU 2022-01 will be effective for us on January 1, 2023 though early adoption is permitted. The adoption of ASU 2022-01 is not expected to have a significant impact on our financial statements.
ASU 2022-02, “Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures.” ASU 2022-02 eliminates the accounting guidance for troubled debt restructurings in Accounting Standards Codification (“ASC”) Subtopic 310-40, Receivables - Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, ASU 2022-02 requires entities to disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of ASC Subtopic 3126-20, Financial Instruments - Credit Losses - Measured at Amortized Cost. ASU 2022-02 will be effective for us on January 1, 2023 though early adoption is permitted. The adoption of ASU 2022-02 is not expected to have a significant impact on our financial statements.
ASU 2022-03, “Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions.” ASU 2022-03 clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. ASU 2022-03 also clarifies that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction and requires certain new disclosures for equity securities subject to contractual sale restrictions. ASU 2022-03 will be effective for us on January 1, 2024 though early adoption is permitted. The adoption of ASU 2022-03 is not expected to have a significant impact on our financial statements.

Changes in the mix of loan geographies, sectors and types or the level of non-performing assets and charge-offs.
Changes in estimates of future reserve requirements based upon the periodic review thereof under relevant regulatory and accounting requirements.
The effects of and changes in trade and monetary and fiscal policies and laws, including the interest rate policies of the Federal Reserve Board.
Inflation, interest rate, securities market and monetary fluctuations.
The effect of changes in laws and regulations (including laws and regulations concerning taxes, banking, securities and insurance) and their application with which we and our subsidiaries must comply.
The soundness of other financial institutions.
Political instability.
Impairment of our goodwill or other intangible assets.
Acts of God or of war or terrorism.

In addition, financial markets and global supply chains may be adversely affected by the current or anticipated impact of military conflict, including the current Russian invasion of Ukraine, terrorism or other geopolitical events.
Further, statements about the potential effects of the ongoing COVID-19 pandemic on our business, financial condition, liquidity and results of operations may constitute forward-looking statements and are subject to the risk that the actual effects may differ, possibly materially, from what is reflected in those forward-looking statements due to factors and future developments that are uncertain, unpredictable and in many cases beyond our control, including the scope and duration of the pandemic, actions taken by governmental authorities in response to the pandemic, and the direct and indirect impact of the pandemic on our customers, clients, third parties and us.
Forward-looking statements speak only as of the date on which such statements are made. We do not undertake any obligation to update any forward-looking statement to reflect events or circumstances after the date on which such statement is made, or to reflect the occurrence of unanticipated events.
COVID-19 Effects and Actions
Our business has been, and continues to be, impacted by the effects of the COVID-19 pandemic. There remains many uncertainties related to COVID-19 including, among other things, the ongoing impact to our customers, employees and vendors; the impact to the financial services and banking industry; and the impact to the economy as a whole as well as the effect of actions taken, or that may yet be taken, or inaction by governmental authorities to mitigate both the economic and health-related effects of COVID-19. Refer to our 2021 Form 10-K for further information regarding (i) the impact of the COVID-19 pandemic on our operations and our results thereof, as well as the impact on our financial position and (ii) legislative and regulatory actions taken related to the COVID-19 pandemic, particularly as they relate to the banking and financial services industry.
Application of Critical Accounting Policies and Accounting Estimates
We follow accounting and reporting policies that 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 credit losses on financial instruments including loans and off-balance-sheet credit exposures are considered to be critical as these policies involve considerable subjective judgment and estimation by management. In the case of loans, the allowance for credit losses is a contra-asset valuation account, calculated in accordance with Accounting Standards Codification (“ASC”) Topic 326 (“ASC 326”) Financial Instruments - Credit Losses, that is deducted from the amortized cost basis of loans to present the net amount expected to be collected. In the case of off-balance-sheet credit exposures, the allowance for credit losses is a liability account, calculated in accordance with ASC 326, reported as a component of accrued interest payable and other liabilities in our consolidated balance sheets. The amount of each allowance account represents management's best estimate of current expected credit losses on these financial instruments considering available information, from internal and external sources, relevant to assessing exposure to credit loss over the contractual term

of the instrument. Relevant available information includes historical credit loss experience, current conditions and reasonable and supportable forecasts. While historical credit loss experience provides the basis for the estimation of expected credit losses, adjustments to historical loss information may be made for differences in current portfolio-specific risk characteristics, environmental conditions or other relevant factors. While management utilizes its best judgment and information available, the ultimate adequacy of our allowance accounts is dependent upon a variety of factors beyond our control, including the performance of our portfolios, the economy, changes in interest rates and the view of the regulatory authorities toward classification of assets. Refer to the 2021 Form 10-K for additional information regarding critical accounting policies.
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 investments by an amount equal to the taxes that would be paid if the income were fully taxable based on a 21% federal tax rate, thus making tax-exempt yields comparable to taxable asset yields.
Results of Operations
Net income available to common shareholders totaled $97.4$117.4 million, or $1.50$1.81 per diluted common share, and $214.9 million, or $3.31 per diluted common share for the three and six months ended March 31,June 30, 2022 compared to $113.9$116.4 million, or $1.77$1.80 per diluted common share, and $230.3 million, or $3.57 per diluted common share for the three and six months ended March 31,June 30, 2021.

The decreaseincrease during the three months ended March 31,June 30, 2022 was primarily the result of a $28.6$31.1 million increase in net interest income and a $6.7 million increase in non-interest income partly offset by a $31.1 million increase in non-interest expense and a $4.7$5.6 million increase in income tax expense. The decrease during the six months ended June 30, 2022 was primarily the result of a $59.7 million increase in non-interest expense and a $10.3 million increase in income tax expense partly offset by an $8.2a $39.2 million increase in net interest income and an $8.2a $14.8 million increase in non-interest income. 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 71.1%72.9% of total revenue during the first threesix months of 2022. 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 inAs of June 30, 2022, approximately 42.0% of our loans had a fixed interest rate, while the remaining loans had floating interest rates that were primarily tied to the prime interest rate. The prime rate remained at 3.25% during 2021. During 2022, the prime rate increased 25 basis points in March to end the first quarter at 3.50%. Our loan portfolio is also impacted by changes in(approximately 29.2%) or the London Interbank Offered Rate (“LIBOR”) (approximately 17.0%). At March 31, 2022, the one-month and three-month U.S. dollar LIBOR interest rates were 0.45% and 0.96%, respectively, while at March 31, 2021, the one-month and three-month U.S. dollar LIBOR interest rates were 0.11% and 0.19%, respectively. We discontinued originating LIBOR-based loans effective December 31, 2021 and have begun to negotiate loans using our preferred replacement index, the American Interbank Offered Rate (“AMERIBOR”), a benchmark developed by the American Financial Exchange, the Secured Overnight Financing Rate (“SOFR”) or a benchmark developed by Bloomberg Index Services (“BSBY”). As of June 30, 2022, approximately 11.7% of loans were tied to one of these indexes. For our currently outstanding LIBOR-based loans, the timing and manner in which each customer’s contract transitions from LIBOR to another rate will vary on a case-by-case basis. We expectOur goal is to complete all transitions by the first quarter of 2023.

Effective July 28, 2022, the Federal Reserve increased the target range for the federal funds rate which is the cost of immediately available overnight funds, remained at zero to 0.25% during 2021. During 2022, the target fed funds rate was increased 25 basis points in March2.25% to end the quarter at 0.25 to 0.50%. In March 2022, the Federal Reserve released projections whereby the midpoint of the projected appropriate target range for the federal funds rate would rise to 1.9% by the end of 20222.50% and to 2.8% by the end of 2023. While there can be no such assurancestated that anythey anticipate on-going increases in the federal fundstarget range will be appropriate. Additionally, the interest rate will occur, these projections imply six 25 basis point increases in the federal funds rate during the remainder of 2022, followed by an additional four 25 basis point increases in 2023.paid on reserve balances was increased to 2.40%.
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. See Item 3. Quantitative and Qualitative Disclosures About Market Risk elsewhere in this report for information about our sensitivity to interest rates. Further analysis of the components of our net interest margin is presented below.

Taxable-equivalent net interest income for the three months ended March 31,June 30, 2022 increased $8.2$31.4 million, or 3.1%11.2%, while taxable-equivalent net interest income for the six months ended June 30, 2022 increased $39.6 million, or 7.3%, compared to the same periodperiods in 2021. The increase in taxable-equivalent net interest income during the three months ended March 31,June 30, 2022 was primarily related to an increase in the average volume of taxable securities, an increase in the average yield on interest-bearing deposits (primarily amounts held in an interest-bearing account at the Federal Reserve) and, to a much lesser extent, an increase in the average volume of tax-exempt securities. The impact of these items was partly offset by a decrease in the average volume of loans combined with decreases in the average yields on loans and tax-exempt securities and increases in the

The decrease in trust and investment management fees during the three months ended June 30, 2022 was primarily due to decreases in estate fees (down $968 thousand) and investment management fees (down $863 thousand), among other things, mostly offset by an increase in oil and gas fees (up $1.8 million).
The increase in trust and investment management fees during the six months ended June 30, 2022 was primarily due to increases in investment management fees (up $1.8 million, or 6.2%), oil and gas fees (up $771$2.6 million), investment management fees (up $966 thousand) and real estate fees (up $626$580 thousand) partly offset by a decrease in estate fees (down $888 thousand). Investment management fees are generally based on the market value of assets within an account and are thus impacted by volatility in the equity and bond markets. The increase in investment management fees during six months ended June 30, 2022 was primarily related to higher average equity valuations as well as an increase in the number of accounts. The decrease in investment management fees during three months ended June 30, 2022 was primarily related to the sharp decline in equity valuations during the second quarter of 2022. Oil and gas fees during the three and six months ended June 30, 2022 were impacted by increases in oil and gas prices. The increasefluctuations in estate fees and real estate fees wasduring the comparable periods were primarily related to an increasevariations in transaction volume.volumes.

The increase during the three months ended June 30, 2022 was primarily related to increases in commercial service charges (up $1.5 million) and overdraft charges on consumer and commercial accounts (up $637$2.1 million and $624 thousand, respectively) and $475 thousand,commercial service charges (up $1.1 million). The increase during the six months ended June 30, 2022 was primarily related to increases in overdraft charges on consumer and commercial accounts (up $2.7 million and $1.1 million, respectively) and commercial service charges (up $2.5 million).
Commercial service charges during the three and six months ended March 31,June 30, 2022 were primarily impacted by an increaseincreases in the volumevolumes of billable services compared to the same periodperiods in 2021, partly offset by an increase in the earnings credit rate.

consumer and $4.1 million commercial) during the six months ended June 30, 2022 compared to $14.4 million ($11.4 million consumer and $3.0 million commercial) during the same period in 2021. The increases in overdraft charges during the three and six months ended March 31,June 30, 2022 were impacted by increases in the volumes of fee assessed overdrafts relative to the same periodperiods in 2021.
In June 2022, we expanded the overdraft grace feature first implemented in April 2021. This feature, which was previously only available to certain consumer demand deposit accounts, is now available to all of our consumer demand deposit accounts, regardless of direct deposit status. With this feature no fees will be assessed on overdrafts of $100 or less. Additionally, we also eliminated fees on non-sufficient and returned items for all consumer deposit accounts. We expect these changes will impact revenue by as much as $3.5 million on an annual basis.
Insurance Commissions and Fees. Insurance commissions and fees for the three and six months ended March 31,June 30, 2022 decreased $705increased $1.0 million, or 9.3%, and increased $298 thousand, or 4.1%1.1%, respectively, compared to the same periodperiods in 2021.

contingent payments are seasonal in nature and are mostly received during the first quarter of each year. This performance related contingent income totaled $1.6$1.8 million and $3.0$3.1 million during the threesix months ended March 31,June 30, 2022 and 2021, respectively. The decrease in performance related contingent income during 2022 was related to low growth within the portfolio and a deterioration in the loss performance of insurance policies previously placed. This deterioration was impacted by a severe weather event in Texas during the first quarter of 2021 that resulted in a significant increase in property and casualty claims and losses. Contingent income also includes amounts received from various benefit plan insurance companies related to the volume of business generated and/or the subsequent retention of such business. This benefit plan related contingent income totaled $813$385 thousand and $1.2 million during the three and six months ended March 31,June 30, 2022, respectively, compared to $625$274 thousand and $899 thousand during the same periodrespective periods in 2021.

Results of Segment Operations
We are managed under a matrix organizational structure whereby our two primary operating segments, Banking and Frost Wealth Advisors, overlap a regional reporting structure. 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. A description of each segment, the methodologies used to measure segment financial performance and summarized operating results by segment are described in Note 15 - Operating Segments in the accompanying notes to consolidated financial statements included elsewhere in this report. Segment operating results are discussed in more detail below.

The increase included a $2.7$2.3 billion increase in non-interest bearing deposits and a $4.9$4.7 billion increase in interest-bearing deposit accounts. Average non-interest bearing deposits made up 41.8%41.4% and 43.2%43.1% of average total deposits during the first threesix months of 2022 and 2021, respectively.
Loans
Details of our loan portfolio are presented in Note 3 - Loans in the accompanying notes to consolidated financial statements included elsewhere in this report. Loans increased $206.1$399.6 million, or 1.3%2.4%, from $16.3 billion at December 31, 2021 to $16.5$16.7 billion at March 31,June 30, 2022. As further discussed below, during the second quarter of 2020, we began originating loans to qualified small businesses under the Paycheck Protection Program (“PPP”) administered by the SBA under the provisions of the CARES Act. Excluding PPP loans, total loans would have otherwise increased $427.4$736.6 million, or 2.7%4.6%, from $15.9 billion at December 31, 2021 to $16.3$16.6 billion at March 31,June 30, 2022. The majority of our loan portfolio is comprised of commercial and industrial loans, energy loans, and real estate loans. Real estate loans include both commercial and consumer balances. Selected details related to our loan portfolio segments are presented below. Refer to our 2021 Form 10-K for a more detailed discussion of our loan origination and risk management processes.
Commercial and Industrial. Commercial and industrial loans increased $219.2$174.3 million, or 4.1%3.2%, from $5.4 billion at December 31, 2021 to $5.6$5.5 billion at March 31,June 30, 2022. 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).

Energy. Energy loans include loans to entities and individuals that are engaged in various energy-related activities including (i) the development and production of oil or natural gas, (ii) providing oil and gas field servicing, (iii) providing energy-related transportation services, (iv) providing equipment to support oil and gas drilling, (v) refining petrochemicals, or (vi) trading oil, gas and related commodities. Energy loans decreased $41.2$89.9 million, or 3.8%8.3%, from $1.1 billion at December 31, 2021 to $1.0 billion$987.9 million at March 31,June 30, 2022. We have recently made efforts to reduce our exposure to energy loans. Nonetheless energy loans remain our largest industry concentration totaling 6.3%5.9% of total loans (also 6.3%5.9% excluding PPP loans) at March 31,June 30, 2022, down from 6.6% of total loans (6.8% excluding PPP loans) at December 31, 2021. The average loan size, the significance of the portfolio and the specialized nature of the energy industry requires a highly prescriptive underwriting policy. Exceptions to this policy are rarely granted. Due to the large borrowing requirements of this customer base, the energy loan portfolio includes participations and SNCs.
Purchased Shared National Credits. 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 $705.6$707.8 million at March 31,June 30, 2022, increasing $7.2$9.5 million, or 1.0%1.4%, from $698.4 million at December 31, 2021. At March 31,June 30, 2022, 25.4%30.1% of outstanding purchased SNCs were related to the construction industry while 23.2%25.8% were related to the energy industry, 15.6%13.7% were related to the financial services industry and 13.6%12.1% were related to the real estate management 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 energy and 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.

Commercial Real Estate. Commercial real estate loans increased $221.8$479.5 million, or 2.9%6.3%, from $7.6 billion at December 31, 2021 to $7.8$8.1 billion at March 31,June 30, 2022. Commercial real estate loans represented 84.5%83.8% of total real estate loans at March 31,June 30, 2022 compared to 84.3% at December 31, 2021. The majority of our commercial real estate loan portfolio consists of commercial real estate mortgages, which includes both permanent and intermediate term loans. 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. At March 31,June 30, 2022, approximately 48.8% of the outstanding principal balance of our commercial real estate loans were secured by owner-occupied properties.
Consumer Real Estate and Other Consumer Loans. The consumer loan portfolio, including all consumer real estate and consumer installment loans, totaledincreased $150.2 million, or 10.6%, from $1.9 billion at both March 31, 2022 and December 31, 2021. Consumer real estate loans increased $22.8 million, or 1.6%, from December 31, 2021.2021 to $2.1 billion at June 30, 2022. Combined, home equity loans and lines of credit made up 60.5%61.3% and 59.8% of the consumer real estate loan total at March 31,June 30, 2022 and December 31, 2021, 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. We have not generally originated 1-4 family mortgage loans since 2000; however, from time to time, we invested in such loans to meet the needs of our customers or for other regulatory compliance purposes. Nonetheless, we expect to begin regular production of 1-4 family mortgage loans for portfolio investment purposes in the second half oflate 2022. Consumer and other loans increased $4.8$22.4 million, or 1.0%4.7%, from December 31, 2021. The consumer and other loan portfolio primarily consists of automobile loans, overdrafts, unsecured revolving credit products, personal loans secured by cash and cash equivalents and other similar types of credit facilities.
Paycheck Protection Program. We have originated loans to qualified small businesses under the PPP administered by the SBA under the provisions of the CARES Act. Loans covered by the PPP may be eligible for loan forgiveness for certain costs incurred related to payroll, group health care benefit costs and qualifying mortgage, rent and utility payments. The remaining loan balance after forgiveness of any amounts is still fully guaranteed by the SBA. Refer to the 2021 Form 10-K for additional details.
During the threesix months ended March 31,June 30, 2022, we recognized approximately $2.6 million in PPP loan related deferred processing fees (net of amortization of related deferred origination costs) as a yield adjustment and this amount is included in interest income on loans. During the threesix months ended March 31,June 30, 2021, we recognized approximately $23.5$62.3 million in PPP loan related deferred net processing fees. As a result of the inclusion of these net fees in interest income, the average yields on PPP loans were 4.45%3.32% during the threesix months ended March 31,June 30, 2022, and 4.39%5.60% during the threesix months ended March 31,June 30, 2021 compared to the stated interest rate of 1.0% on these loans. PPP related deferred processing fees and deferred origination costs are not expected to significantly impact interest income on loans in future periods.

Non-accrual loans at March 31,June 30, 2022 decreased $4.7$18.6 million from December 31, 2021 primarily due to a decreasedecreases in non-accrual commercial and industrial loans and, energy loans partly offset by an increase into a lesser extent, commercial real estate and energy loans. The decreases in commercial were primarily related to principal payments, loans returning to accrual and charge offs.
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. There were no non-accrual commercial and industrial loans in excess of $5.0 million at March 31,June 30, 2022 or December 31, 2021. Non-accrual energy loans included one credit relationship in excess of $5$5.0 million totaling $8.2$7.6 million at March 31,June 30, 2022. This credit relationship was previously reported as non-accrual with an aggregate balance of $9.6 million at

December 31, 2021. The decrease in the aggregate balance of this credit relationship was related to principal payments made by the borrower. 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. Non-accrual commercial real estate loans included one credit relationship in excess of $5.0 million totaling $5.8 million at March 31, 2022 while thereThere were no non-accrual commercial real estate loans in excess of $5.0 million at June 30, 2022 or December 31, 2021.
Allowance for Credit Losses
In the case of loans and securities, allowances for credit losses are contra-asset valuation accounts, calculated in accordance with Accounting Standards Codification (“ASC”) Topic 326 (“ASC 326”) Financial Instruments - Credit Losses, that are deducted from the amortized cost basis of these assets to present the net amount expected to be collected. In the case of off-balance-sheet credit exposures, the allowance for credit losses is a liability account, calculated in accordance with ASC 326, reported as a component of accrued interest payable and other liabilities in our consolidated balance sheets. The amount of each allowance account represents management's best estimate of current expected credit losses (“CECL”) on these financial instruments considering available information, from internal and external sources, relevant to assessing exposure to credit loss over the contractual term of the instrument. Relevant available information includes historical credit loss experience, current conditions and reasonable and supportable forecasts. While historical credit loss experience provides the basis for the estimation of expected credit losses, adjustments to historical loss information may be made for differences in current portfolio-specific risk characteristics, environmental conditions or other relevant factors. While management utilizes its best judgment and information available, the ultimate adequacy of our allowance accounts is dependent upon a variety of factors beyond our control, including the performance of our portfolios, the economy, changes in interest rates and the view of the regulatory authorities toward classification of assets. See our 2021 Form 10-K for additional information regarding our accounting policies related to credit losses.

As more fully described in our 2021 Form 10-K, we measure expected credit losses over the life of each loan utilizing a combination of models which measure probability of default and loss given default, among other things. The measurement of expected credit losses is impacted by loan/borrower attributes and certain macroeconomic variables. Models are adjusted to reflect current impact of certain macroeconomic variables as well as their expected changes over a reasonable and supportable forecast period.
In estimating expected credit losses as of March 31,June 30, 2022, we utilized the Moody’s Analytics MarchJune 2022 Consensus Scenario (the “March“June 2022 Consensus Scenario”) to forecast the macroeconomic variables used in our models. The MarchJune 2022 Consensus Scenario was based on the review of a variety of surveys of baseline forecasts of the U.S. economy. The MarchJune 2022 Consensus Scenario projections included, among other things, (i) U.S. Nominal Gross Domestic Product annualized quarterly growth rate of 8.7%6.80% in the second quarterhalf of 2022 followed by average annualized quarterly growth rates of 4.4% during 20224.10% in 2023 and 4.6%4.30% through the end of the forecast period in the firstsecond quarter of 2024; (ii) average U.S. unemployment rate of 3.7%3.57% in the second quarterhalf of 2022 and remaining fairly flat through the end of the forecast period where it is projected to be 3.6% in the first quarter of 2024; (iii) Texas unemployment rate of 4.0%3.58% in the second quarter of 2024; (iii) average Texas unemployment rate of 4.11% in the second half of 2022 and improving to 3.7%3.57% by the end of the forecast in the firstsecond quarter of 2024; (iv) projected average 10 year Treasury rate of 2.08%2.95% in the second quarter of 2022, increasing to average projected rates of 2.15% during the remainderhalf of 2022, and 2.33%remaining fairly flat through the end of the forecast period in the firstsecond quarter of 2024.2024 where it is projected to be 2.91%.
In estimating expected credit losses as of December 31, 2021, we utilized the Moody’s Analytics December 2021 Consensus Scenario (the “December 2021 Consensus Scenario”) to forecast the macroeconomic variables used in our models. The December 2021 Consensus Scenario was based on the review of a variety of surveys of baseline forecasts of the U.S. economy. The December 2021 Consensus Scenario projections included, among other things, (i) U.S. Nominal Gross Domestic Product annualized quarterly growth rate of 6.4% in the first quarter of 2022, followed by annualized quarterly growth rates in the range of 3.8% to 5.4% during the remainder of 2022 and an average annualized growth rate of 4.8% through the end of the forecast period in the fourth quarter of 2023; (ii) U.S. unemployment rate of 4.3% in the first quarter of 2022 improving to 3.7% by the end of the forecast period in the fourth quarter of 2023 with Texas unemployment rates slightly higher at those dates; and (iii) projected average 10 year Treasury rate of 1.59% in the first quarter of 2022, increasing to average projected rates of 1.75% during the remainder of 2022 and 2.10% in 2023.
The overall loan portfolio, excluding PPP loans which are fully guaranteed by the SBA, as of March 31,June 30, 2022 increased $427.4$736.6 million, or 2.7%4.6%, compared to December 31, 2021. This increase included a $221.8$479.5 million, or 2.9%6.3%, increase in commercial real estate loans, a $219.2$174.3 million, or 4.1%3.2%, increase in commercial and industrial loans, a $22.8$150.2 million, or 1.6%10.6%, increase in consumer real estate loans and a $4.8$22.4 million, or 1.0%4.7%, increase in consumer and other loans partly offset by a $41.2an $89.9 million, or 3.8%8.3%, decrease in energy loans.

The weighted average risk grade for commercial and industrial loans increased to 6.346.38 at March 31,June 30, 2022 compared to 6.22 at December 31, 2021. This increase was primarily due to an increase in the weighted-average risk grade of pass-grade commercial and industrial loans to 6.186.23 at March 31,June 30, 2022 from 6.01 at December 31, 2021. Commercial and industrial loans graded “watch” and “special mention” (risk grades 9 and 10) decreased $48.1$25.6 million during the first threesix months of 20212022 while classified commercial and industrial loans decreased $3.3$13.0 million. Classified loans consist of loans having a risk grade of 11, 12 or 13. The weighted-average risk grade for energy loans decreased to 5.895.82 at March 31,June 30, 2022 from 6.06 at December 31, 2021. The decrease in the weighted average risk grade was primarilypartly related to a $27.6$23.3 million decrease in energy loans graded “watch” and “special mention” (risk grades 9 and 10) and an $4.5 million decrease in classified energy loans. Pass. Additionally, pass grade energy loans decreased $9.1$67.2 million and the weighted-average risk grade of pass grade energy loans decreased slightly from 5.78 at December 31, 2021 to 5.715.57 at March 31,June 30, 2022. The weighted average risk grade for commercial real estate loans decreased to 7.117.09 at March 31,June 30, 2022 from 7.19 at December 31, 2021. Pass grade commercial real estate loans increased $361.0$612.0 million while commercialthe weighted-average risk grade of such loans decreased from 6.92 at December 31, 2021 to 6.89 June 30, 2022. Commercial real estate loans graded as “watch” and “special mention” decreased $107.0$99.5 million and classified commercial real estate loans decreased $32.2$33.0 million.
As noted above, our credit loss models utilized the economic forecasts in the Moody's MarchJune 2022 Consensus Scenario for our estimated expected credit losses as of March 31,June 30, 2022 and the Moody's December 2021 Consensus Scenario for our estimate of expected credit losses as of December 31, 2021. We qualitatively adjusted the model results based on these scenarios for various risk factors that are not considered within our modeling processes but are nonetheless relevant in assessing the expected credit losses within our loan pools. These qualitative factor, (“Q-Factor”)or Q-Factor, adjustments are discussed below.
Q-Factor adjustments are based upon managementmanagement's judgment and current assessment as to the impact of risks related to changes in lending policies and procedures; economic and business conditions; loan portfolio attributes and credit concentrations; and external factors, among other things, that are not already captured within the modeling inputs, assumptions and other processes. Management assesses the potential impact of such items within a range of severely negative impact to positive impact and adjusts the modeled expected credit loss by an aggregate adjustment percentage based upon the assessment.

As a result of this assessment as of March 31,June 30, 2022, modeled expected credit losses were adjusted upwards by a weighted-average Q-Factor adjustment of approximately 1.9%2.5%, resulting in a $1.4$2.0 million total adjustment, down from approximatelycompared to 2.3% at December 31, 2021, which resulted in a $1.8 million total adjustment. The weighted-average Q-Factor adjustment at March 31,June 30, 2022 was based on a limited negative expected impact on our commercial and industrial and commercial real estate loan portfolios related to changes in loan portfolio concentrations; a limited negative expected impact on all of our loan portfolios related to changes in the volumes and severity of loan delinquencies, changes in risk grades and adverse classifications; a limited negative expected impact on our commercial and consumer real estate portfolios related to the potential deterioration of collateral values (no expected impact related to our commercial and industrial and consumer portfolios); a negative expected impact associated with national, regional and local economic and business conditions and developments that affect the collectability of loans; a severely negative expected impact from other risk factors associated with our commercial real estate construction and land loan portfolios, particularly the risks related to expected extensions; and no impact to any of our loan portfolios related to changes lending policies procedures and underwriting standards;standards (except for our consumer and other portfolio, which was limited negative); and loan portfolio attributes; changes in risk grades; changes in the volumes and severity of loan delinquencies; and adverse classifications and potential deterioration of collateral values.attributes, among other things.
We have also provided additional qualitative adjustments, or management overlays, as of March 31,June 30, 2022 as management believes there are still significant risks impacting certain categories of our loan portfolio. Q-Factor and other qualitative adjustments as of March 31,June 30, 2022 are detailed in the table below.

Model overlays are qualitative adjustments to address the effect of unusually large positive changes in certain economic variables used by our commercial real estate credit loss models. These adjustments are determined based upon minimum reserve ratios for our commercial real estate - owner occupied, commercial real estate - non-owner occupied and commercial real estate - construction loan portfolios.

Office building overlays are qualitative adjustments to address longer-term concerns over the utilization of commercial office space which could impact the long-term performance of some types of office properties within our commercial real estate loan portfolio. These adjustments are determined based upon minimum reserve ratios for loans within our commercial real estate - non-owner occupied and commercial real estate - construction loan portfolios that have risk grades of 8 or worse.
The down-side scenario overlay is a qualitative adjustment for our commercial and industrial loan portfolio to address the significant risk of economic recession as a result of inflation; labor shortages; disruption in financial markets and global supply chains; further oil price volatility; and the current or anticipated impact of military conflict, including the current war between Russia and Ukraine, terrorism or other geopolitical events. Factors such as these are outside of our control but nonetheless affect customer income levels and could alter anticipated customer behavior, including borrowing, repayment, investment and deposit practices. To determine this qualitative adjustment, we use an alternative, more pessimistic economic scenario to forecast the macroeconomic variables used in our models. As of March 31,June 30, 2022, we used the Moody’s Analytics MarchJune 2022 S3 Alternative Scenario Downside - 90th Percentile (the “March“June 2022 S3 Scenario”). In modeling expected credit losses using this scenario, we also assume each loan within our modeled loan pools is downgraded by one risk grade level. The qualitative adjustment is based upon the amount by which the alternative scenario modeling results exceed those of the primary scenario used in estimating credit loss expense, adjusted based upon management's assessment of the probability that this more pessimistic economic scenario will occur.
Post-pandemic overlays are qualitative adjustments to address elevated risk associated with certain industries and not addressed in other qualitative adjustments, due to the lingering, post-pandemic effects of COVID-19, particularly the impact of behavioral changes in business travel and entertainment, labor and staffing shortages, and inflation. These adjustments are determined based upon minimum reserve ratios, stratified by risk grade, for loans to customers within the hotel, restaurant and entertainment industries. These industries were considered the most at risk based upon a comprehensive review of the financial condition and overall outlook of the borrowers within these portfolios. We are continuing to monitor these customers closely as they have been, and are expected to continue to be, more significantly impacted by the lingering, post-pandemic effects of COVID-19.

Credit concentration overlays are qualitative adjustments based upon statistical analysis to address relationship exposure concentrations within our loan portfolio. Variations in loan portfolio concentrations over time cause expected credit losses within our existing portfolio to differ from historical loss experience. Given that the allowance for credit losses on loans reflects expected credit losses within our loan portfolio and the fact that these expected credit losses are uncertain as to nature, timing and amount, management believes that segments with higher concentration risk are more likely to experience a high loss event. Due to the fact that a significant portion of our loan portfolio is concentrated in large credit relationships and because of large, concentrated credit losses in recent years, management made the qualitative adjustments detailed in the table above to address the risk associated with such a relationship deteriorating to a loss event.
The consumer overlay is a qualitative adjustment for our consumer and other loan portfolio to address the risk associated with the level of unsecured loans within this portfolio and other risk factors. Unsecured consumer loans have an elevated risk of loss in times of economic stress as these loans lack a secondary source of repayment in the form of hard collateral. This adjustment was determined by analyzing our consumer loan charge-off trends as well as those of the general banking industry. Management deemed it appropriate to consider an additional overlay to the modeled forecasted losses for the unsecured consumer portfolio.
As of December 31, 2021, we provided qualitative adjustments, as detailed in the table below. Though largely similar to those described above, furtherFurther information regarding these qualitative adjustments is provided in our 2021 Form 10-K.

We recorded a net credit loss expense related to loans totaling $4.5 million$68 thousand for the threesix months ended March 31,June 30, 2022 while no net credit loss expense or benefit was recognized during the same period in 2021. Net credit loss expense/benefit for each portfolio segment reflects the amount needed to adjust the allowance for credit losses allocated to that segment to the level of expected credit losses determined under our allowance methodology after net charge-offs have been recognized. The net credit loss expense related to loans during the first threesix months of 2022 primarily reflects increases in expected credit losses associated with commercial and industrial loans, primarily related to the down-side scenario overlay discussed above, and consumer and other loans, primarily related to an increase in modeled losses, as well as the level of net charge-offs associated with these loan portfolio segments. The impact of these items was partly offset by a decrease in expected credit losses associated with commercial real estate loans, primarily related to a decrease in expected credit losses related to certain pandemic impacted industries.industries and a reduction in the minimum reserve ratio for our commercial real estate - owner occupied portfolio. The ratio of the allowance for credit losses on loans to total loans was 1.49% (1.51%1.43% (1.44% excluding PPP loans) at March 31,June 30, 2022 compared to

Table of Contents
1.52% (1.56% excluding PPP loans) at December 31, 2021. Management believes the recorded amount of the allowance for credit losses on loans is appropriate based upon management’s best estimate of current expected credit losses within the existing portfolio of loans. Should any of the factors considered by management in making this estimate change, our estimate of current expect credit losses could also change, which could affect the level of future credit loss expense related to loans.
Allowance for Credit Losses - Off-Balance-Sheet Credit Exposures. The allowance for credit losses on off-balance-sheet credit exposures totaled approximately $45.9$50.2 million and $50.3 million at March 31,June 30, 2022 and December 31, 2021, respectively. The level of the allowance for credit losses on off-balance-sheet credit exposures depends upon the volume of outstanding commitments, underlying risk grades, the expected utilization of available funds and forecasted economic conditions impacting our loan portfolio. Our policies and methodology used to estimate the allowance for credit losses on off-balance-sheet credit exposures are further described in our 2021 Form 10-K. We recognized a net credit loss benefit related to off-balance-sheet credit exposures totaling $4.5 million$68 thousand during the threesix months ended March 31,June 30, 2022 compared to a net credit loss expense of $65 thousand$4.4 million during the same period in 2021. The credit loss benefit during the first three months of 2022 was partly impacted by the upgrade of a large credit commitment within our SNC portfolio.
Capital and Liquidity
Capital. Shareholders’ equity totaled $3.8$3.3 billion and $4.4 billion at March 31,June 30, 2022 and December 31, 2021, respectively. The decrease was primarily related to the accumulated other comprehensive income/loss component of shareholders’ equity which decreased to a net, after-tax, unrealized loss of $371.8$874.2 million at March 31,June 30, 2022 from a net, after-tax unrealized gain of $347.3 million at December 31, 2021. The change was primarily due to a $719.5 million$1.2 billion net, after-tax, decrease in the fair value of securities available for sale. Other uses of capital during the threesix months ended March 31,June 30, 2022 included $50.1$100.3 million of dividends paid on preferred and common stock and $996 thousand of treasury stock purchases. Sources of capital during the threesix months ended March 31,June 30, 2022 included net income of $99.1$218.2 million, $5.7$6.5 million in proceeds from stock option exercises and $2.1$5.5 million related to stock-based compensation.
Under the Basel III Capital Rules, we have 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 do not increase or reduce regulatory capital and are not included in the calculation of our regulatory capital ratios. In connection with the adoption of ASC 326 on January 1, 2020, we also elected to exclude, for a transitional period, the effects of credit loss accounting under CECL in the calculation of our regulatory capital and regulatory capital 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 7 - Capital and Regulatory Matters in the accompanying notes to consolidated financial statements included elsewhere in this report.
We paid a quarterly dividend of $0.75 per common share during each of the first quarterand second quarters of 2022 and a quarterly dividend of $0.72 per common share during each of the first quarterand second quarters of 2021. These dividend amounts equate to a common stock dividend payout ratio of 49.7%45.1% and 40.5%40.1% during the first threesix months of 2022 and 2021, respectively. Our ability to declare or pay dividends on, or purchase, redeem or otherwise acquire, shares of our capital stock may be impacted by certain restrictions described in Note 7 - Capital and Regulatory Matters in the accompanying notes to consolidated financial statements included elsewhere in this report.
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 January 26, 2022 our board of directors authorized a $100.0 million stock repurchase program, allowing us to repurchase shares of our common stock over a one-year period from time to time at various prices in the open market or through private transactions. No shares have been repurchased under this plan or under a prior plan during the reported periods.

Liquidity. As more fully discussed in our 2021 Form 10-K, 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. Our principal source of funding has been our customer deposits, supplemented by our short-term and long-term borrowings as well as maturities of securities and loan amortization. As of March 31,June 30, 2022, we had approximately $13.4$12.7 billion held in an interest-bearing account at the Federal Reserve. We also have the ability to borrow funds as a member of the Federal Home Loan Bank (“FHLB”). As of March 31,June 30, 2022, based upon available, pledgeable collateral, our total borrowing capacity with the FHLB was approximately $3.2 billion.

Furthermore, at March 31,June 30, 2022, we had approximately $12.8$14.1 billion in securities that were unencumbered by a pledge and could be used to support additional borrowings through repurchase agreements or the Federal Reserve discount window, as needed.
Since Cullen/Frost is a holding company and does not conduct operations, its primary sources of liquidity are dividends upstreamed from Frost Bank and borrowings from outside sources. Banking regulations may limit the amount of dividends that may be paid by Frost Bank. See Note 7 - Capital and Regulatory Matters in the accompanying notes to consolidated financial statements included elsewhere in this report regarding such dividends. At March 31,June 30, 2022, Cullen/Frost had liquid assets, including cash and resell agreements, totaling $476.0$432.8 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 2021 Form 10-K. There has been no significant change in the types of market risks we face since December 31, 2021.
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 March 31,June 30, 2022, 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 2.1%2.9% and 5.8%6.1%, respectively, relative to the flat-rate case over the next 12 months, while a 50100 and 175 basis point ratable decreasedecreases in interest rates would result in a negative variancevariances in net interest income of 3.7%2.7% and 8.3%, respectively, relative to the flat-rate case over the next 12 months. For modeling purposes, as of December 31, 2021, 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 2.8% and 7.1%, respectively, relative to the flat-rate case over the next 12 months, while a 25 basis point ratable decrease in interest rates would result in a negative variance in net interest income of 3.0% relative to the flat-rate case over the next 12 months. Both the March 31, 2022 and December 31, 2021 model simulations for increased interest rates were impacted by the assumption, for modeling purposes, that we will begin to pay interest on commercial demand deposits (those not already receiving an earnings credit rate) in the first and second quarters of 2022, respectively, as further discussed below. The likelihood of a decrease in interest rates beyond 50175 basis points as of March 31,June 30, 2022 and 25 basis points as of December 31, 2021 was considered remote given prevailing interest rate levels.
We do not currently pay interest on a significant portion of our commercial demand deposits. Any interest rate that would ultimately be paid on these commercial demand deposits would likely depend upon a variety of factors, some of which are beyond our control. Our June 30, 2022 model simulations do not assume any payment of interest on commercial demand deposits (those not already receiving an earnings credit) while our modeling simulations as of December 31, 2021 assumed a slightly aggressive pricing structure with regards to interest payments on commercial demand deposits (those not already receiving an earnings credit) with interest payments assumed to begin in the first quarter of 2022. This pricing structure on commercial demand deposits assumed a deposit pricing beta of 25%. The pricing beta is a measure of how much deposit rates reprice, up or down, given a defined change in market rates. As of June 30, 2022, management believes, based on our experience during the last interest rate cycle, that it is less likely we will pay interest on these deposits as rates increase.
The model simulations as of March 31,June 30, 2022 indicate that our projected balance sheet is slightly less asset sensitive in comparison to our balance sheet as of December 31, 2021. The decreased asset sensitivity was partly due to a decrease in the relative proportion of interest-bearing deposits (primarily amounts held in an interest-bearing account at the Federal Reserve) and federal funds sold to projected average interest-earning assets combined with an increase in the relative proportion of fixed-rate taxable securities to projected average interest-earning assets. Interest-bearing deposits and federal funds sold are more immediately impacted by changes in interest rates in comparison to our other categories of earning assets. Additionally, the positive impact of increasing interest rates was partly mitigated due to an increase in the relative proportion of interest-bearing deposit liabilities to total deposits as of March 31, 2022 compared to December 31, 2021, resulting in a higher projected cost of deposits.
We do not currently pay interest on a significant portion of our commercial demand deposits. Any interest rate that would ultimately be paid on these commercial demand deposits would likely depend upon a variety of factors, some of which are beyond our control. Our modeling simulations as of March 31, 2022 and December 31, 2021 assume a slightly aggressive pricing structure with regards to interest payments on commercial demand deposits (those not already receiving an earnings credit) with interest payments assumed to begin in the second and first quarters of 2022, respectively. This pricing structure on commercial demand deposits assumes a deposit pricing beta of 25%. The pricing beta is a measure of how much deposit rates reprice, up or down, given a defined change in market rates.
As of March 31,June 30, 2022, the effects of a 200 basis point increase and a 50100 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.
