Results of Operations
Net Interest Revenue and Net Interest Margin

Net interest revenue is the interest earned on debt securities, loans and other interest-earning assets less interest paid for interest-bearing deposits and other borrowings. The net interest margin is calculated by dividing tax-equivalent net interest revenue by average interest-earning assets. Net interest spread is the difference between the average rate earned on interest-earning assets and the average rate paid on interest-bearing liabilities. Net interest margin is typically greater than net interest spread due to interest income earned on assets funded by non-interest bearing liabilities such as demand deposits and equity.

Tax-equivalent net interest revenue totaled $324.5$295.7 million for the secondfirst quarter of 2023,2024, compared to $354.6$298.8 million for the prior quarter. Compared to the firstfourth quarter of 2023, net interest revenue decreased $24.4$3.4 million from changes in interest rates and $5.8 millionincreased $308 thousand from changes in earning assets. Table 1 shows the effect on net interest revenue from changes in average balances and interest rates for various types of earning assets and interest-bearing liabilities.

Average earning assets increased $2.0 billion$520 million compared to the firstfourth quarter of 2023. The average balance of trading securities increased $1.2 billion due to favorable market opportunities. Average loan balances increased $413$243 million, largely due to growth in commercial andloans, partially offset by a reduction in commercial real estate loans. The average balance of available for sale securities, which consists largely of residential and commercial mortgage-backed securities guaranteed by U.S. government agencies, increased $295 million. Average interest-bearing cash and cash equivalents grew $92$475 million while the average balance of trading securities decreased $77 million.

Total average deposits declined by $1.1increased $1.3 billion compared toover the firstfourth quarter of 2023, including a $1.4$2.1 billion decreaseincrease in demandinterest-bearing deposits, partially offset by a $295$747 million increasedecrease in interest-bearingdemand deposits. Funds purchased and repurchase agreements grew $1.9declined $1.2 billion while other borrowings increased $763decreased $276 million.

Net interest margin was 3.00 percent2.61% compared to 3.45 percent2.64% in the fourth quarter of 2023 driven by continued demand deposit migration and deposit repricing. For the first quarter of 2023. Growth in2024, our trading assets drove a 9 basis point decline incore net interest margin with deposit repricing activity primarily driving the remaining 36 basis point reduction. In recent prior quarters, the rapid pace of market interest rate increases grew net interest margin as our earning assets, led by our significant percentage of variable-rate loans, repriced atexcluding trading activities, a higher rate and faster pace than our interest-bearing liabilities. In the past two quarters, deposit price competition and liability mix shift have driven compressionnon-GAAP measure, was 2.97% compared to 3.03% in the net interest margin.prior quarter. The tax-equivalent yield on earning assets was 5.29 percent,5.73%, an increase of 239 basis points. Loan yields grew 364 basis points to 7.03 percent.7.40%. The available for sale securities portfolio yield increased 1321 basis points to 3.00 percent.3.48%. The yield on trading securities grew 7 basis points to 5.12% and the yield on interest-bearing cash and cash equivalents increased 113decreased 34 basis points to 5.41 percent.4.96%.

Funding costs were 3.27 percent, an 844.08%, a 10 basis point increase over the prior quarter. The cost of interest-bearing deposits increased 7326 basis points to 2.56 percent.3.69%. The cost of funds purchased and repurchase agreements increased 125decreased 74 basis points to 4.58 percent4.05% while the cost of other borrowings increased 391 basis pointspoint to 5.12 percent.5.56%. This beneficial mix shift was enabled by the growth of interest-bearing deposits. The benefit to net interest margin from assets funded by non-interest liabilities was 9896 basis points, an increasea decrease of 162 basis points.

Our overall objective is to manage the Company's balance sheet for changes in interest rates as is further described in the Market Risk section of this report. Approximately 80 percent81% of our commercial and commercial real estate loan portfolios are either variable rate or fixed rate that will reprice within one year. These loans are funded primarily by deposit accounts that are either non-interest bearing, or that reprice more slowly than the loans. The result is a balance sheet that is asset sensitive, which means that assets generally reprice more quickly than the liabilities. One of the strategies that we use to manage toward a relative rate-neutral position is to purchase fixed ratefixed-rate residential mortgage-backed securities issued primarily by U.S. government agencies and fund them with market-rate-sensitivemarket rate-sensitive liabilities. The liability-sensitive nature of this strategy provides an offset to the asset-sensitive characteristics of our loan portfolio. We also may use derivative instruments to manage our interest rate risk. 

The effectiveness of these strategies is reflected in the overall change in net interest revenue due to changes in interest rates as shown in Table 1 and in the interest rate sensitivity projections as shown in the Market Risk section of this report.

Certain percentage increases (decreases) in non-fees and commissions revenue are not meaningful for comparison purposes based on the nature of the item.

Fees and commissions revenue

Diversified sources of fees and commissions revenue are a significant part of our business strategy and represented 38 percent41% of totalcombined net interest revenue for the second quarter of 2023, excludingbefore provision for credit losses and gainsfees and losses on other assets, securities and derivatives andcommissions revenue for the change in the fair valuefirst quarter of mortgage servicing rights.2024. We believe that a variety of fee revenue sources provides diversification to changes resulting from market or economic conditions such as interest rates, values in the equity markets, commodity prices and consumer spending, all of which can be volatile. Many of the economic factors, such as risingdecreasing interest rates, that we expect will result in growtha decline in net interest revenue or fiduciary and asset management revenue may also affectincrease mortgage banking production volumes and related trading. The velocity of changes in market conditions and interest rates may result in timing differences between when offsetting impacts and benefits are realized. Generally, for operating revenues not as directly related to movement in interest rates, we expect growth to come through offering new products and services and by further development of our presence in other markets. However, current and future economic conditions, regulatory constraints, increased competition and saturation in our existing markets could affect the rate of future increases.

Brokerage and Trading Revenue

Brokerage and trading revenue, which includes revenues from trading, customer hedging, retail brokerage, insurance brokerage and investment banking, increased $12.6decreased $1.7 million or 24 percent3% compared to the firstfourth quarter of 2023.

Trading revenue also includes net realized and unrealized gains and losses on municipal securities and other financial instruments that we sell to institutional customers, along with changes in the fair value of financial instruments we hold as economic hedges against market risk of our trading securities. Trading revenue was $36.9$37.5 million, a $9.3$1.9 million increase over the prior quarter, primarily related to increased trading activity largely due to a higher volume ofin U.S. government agency residential mortgage-backed securities and related derivative contracts trading volumes.securities.

Customer hedging revenue is based primarily on realized and unrealized changes in the fair value of derivative contracts held for customer risk management programs. As more fully discussed under Customer Risk Management Programs in Note 3 of the Consolidated Financial Statements, we offer commodity, interest rate, foreign exchange and equity derivatives to our customers. Customer hedging revenue totaled $13.6$6.3 million, an increasea decrease of $5.3$1.3 million, driven by less energy customer activity. Customer hedging revenue includes credit valuation adjustments of the fair value of derivatives to reflect the risk of counterparty default.

Investment banking, which includes fees earned upon completion of underwriting, financial advisory services and loan syndication fees, totaled $8.3$10.7 million for the second quarter of 2023, a decrease of $1.0 million compared to the first quarter of 2023, primarily related to2024 and was relatively consistent with the timing and volume of transactions. A reduction in syndication activity was partially offset by higher underwriting fees.prior quarter.
Transaction Card Revenue

Transaction card revenue includes revenues from processing transactions on behalf of members of our TransFund electronic fund transfer network, merchant services fees paid by customers for account management and electronic processing of card transactions and interchange fees from our corporate card program. Transaction card revenue totaled $26.0$25.5 million for the secondfirst quarter of 2023, relatively consistent with2024, a $3.4 million decrease, primarily due to seasonally elevated fourth quarter activity and one less day in the prior quarter.
Fiduciary and Asset Management Revenue

Fiduciary and asset management revenue is earned through managing or holding of assets for customers and executing transactions or providing related services. Fiduciary and asset management revenue is largely based on the fair value of assets. Rates applied to asset values vary based on the nature of the relationship. Fiduciary relationships and managed asset relationships generally have higher fee rates than non-fiduciary and/or managed relationships. Fiduciary and asset management revenue grew $2.3was $55.3 million overfor the first quarter of 2024, a $3.9 million increase over the fourth quarter of 2023, led by higher seasonal tax preparation fee income.largely related to movement in the equity markets.

Other revenue decreased $2.1 million or 14% compared to the fourth quarter of 2023, largely due to a reduction in fees earned on derivative counterparty margin.

Net gains on other assets, securities and derivatives

NetOther gains, on other assetsnet, were $12.6$4.3 million for the secondfirst quarter of 20232024 compared to net gains$40.5 million in the fourth quarter of $2.32023. The prior quarter included a $31.0 million pre-tax gain, before related professional fees, on the sale of BOKFI.

Losses on available for sale securities were $45.2 million in the first quarter of 2023. The current quarter included a gain on alternative investments of $8.1 million, largely attributable to merchant banking activity. Changes in fair value related to deferred compensation investments increased $2.7 million. We also recognized a $3.0 million loss on2024 as we repositioned the sale of available for sale securities portfolio by selling approximately $783 million of lower-yielding debt securities. We expect the gain on conversion of our Visa B shares under the Exchange Offer will offset the realized losses on the repositioning. The Exchange Offer opened on April 8, 2024 and is scheduled to expire at end of day on May 3, 2024. Losses on available for sale securities were $27.6 million in the secondfourth quarter of 2023 related to improve the overall economicsrepositioning of the securities portfolio, going forward.offsetting the gain from the sale of BOKFI.

As discussed in the Market Risk section following, the fair value of our mortgage servicing rights ("MSRs")MSRs changes in response to changes in primary mortgage loan rates and other assumptions. We attempt to mitigate the earnings volatility caused by changes in the fair value of MSRs by designating certain financial instruments as an economic hedge. Changes in the fair value of these instruments are generally expected to partially offset changes in the fair value of MSRs.

Income Taxes

The effective tax rate was 22.5 percent for the second quarter of 2023 and 22.0 percent21.70% for the first quarter of 2023. The effective rate2024, 25.97% for the six months ended June 30,fourth quarter of 2023 and June 30, 2022 were 22.3 percent22.03% and 21.1 percent, respectively, increasing primarilyfor the first quarter of 2023. The fourth quarter of 2023 included an acceleration of $3.1 million of tax expense as a result of exiting three low income housing tax credit investments. When compared to the first quarter of 2023, the effective tax rate also decreased due to higherlower forecasted and actual pre-tax income.
Lines of Business

We operate three principal lines of business: Commercial Banking, Consumer Banking and Wealth Management. Commercial Banking includes lending, treasury and cash management services and customer risk management products for small businesses, middle market and larger commercial customers. Commercial Banking also includes the TransFund EFT network. Consumer Banking includes retail lending and deposit services, lending and deposit services to small business customers served through our consumer branch network and all mortgage banking activities. Wealth Management provides fiduciary services, private banking services, insurance and investment advisory services in all markets. Wealth Management also underwrites state and municipal securities and engages in brokerage and trading activities.

In addition to our lines of business, we have a Funds Management unit. The primary purpose of this unit is to manage our overall liquidity needs and interest rate risk. Each line of business borrows funds from and provides funds to the Funds Management unit as needed to support their operations. Operating results for Funds Management and other include the effect of interest rate risk positions and risk management activities, securities gains and losses including impairment charges, the provision for credit losses in excess of net loans charged off, tax planning strategies and certain executive compensation costs that are not attributed to the lines of business. The Funds Management unit also initially recognizes accruals for loss contingencies when losses become probable. Actual losses are recognized by the lines of business if the accruals are settled.

We allocate resources and evaluate the performance of our lines of business using the net direct contribution, which includes the allocation of funds and capital costs. Credit costs are attributed to the lines of business based on net loans charged off or recovered. The difference between credit costs attributed to the lines of business and the consolidated provision for credit losses is attributed to Funds Management. In addition, we measure the performance of our business lines after allocations of certain indirect expenses and taxes based on statutory rates.

The cost of funds borrowed from the Funds Management unit by the operatingNet interest income in our lines of business reflects our internal funds transfer pricing methodology. The funds transfer pricing methodology is transfer priced at rates that approximate market rates for funds with similar repricingthe process by which the Company allocates interest income and cash flow characteristics. Market rates are generally based onexpense to the applicable wholesale borrowing rates orlines of business and transfers the primary interest rate swap rates, adjusted for prepayment risk and liquidity risk. This method of transfer-pricing funds that support assets of the operating lines of business tends to insulate them from interest rate risk.

The value of funds provided by the operating lines of businessrisk to the Funds Management unit is also based on rates that approximate wholesale market rates forunit. The funds with similar repricing and cash flow characteristics. Market rates are generally based on a proxy of wholesale borrowing rates ortransfer pricing methodology considers the interest rate swap rates. The funds credit formula appliedand liquidity risk characteristics of assets and liabilities. Periodically, the methodology and assumptions utilized in transfer pricing are adjusted to deposit products with indeterminate maturities is established based on their repricing characteristics reflected in a combinationreflect economic conditions and other factors, which may impact the allocation of the short-term wholesale funding rate and a moving average of an intermediate term swap rate, with an appropriate spread applied to both. Shorter duration products are weighted towards the short term wholesale funding rates and longer duration products are weighted towards the intermediate swap rates. The expected duration ranges from 30 days for certain rate-sensitive deposits to five years. For indeterminate-maturity deposits, annual adjustments are madenet interest income to the funds credit formula each January that attribute more or less deposit credit value to the business lines dependent upon historical and forward-looking interest rate expectations, which are then held constant throughout the remainder of the year. After several years of decreased funding credits provided to business lines from a sustained low interest rate environment, increases in short-term and long-term rates in response to the Federal Reserve's actions to control inflation caused a commensurate increase in funding credits to business lines in the first quarter of 2023, with the offset to Funds Management and other.business.

Economic capital is assigned to the business units by a capital allocation model that reflects management's assessment of risk. This model assigns capital based upon credit, operating, interest rate and other market risk inherent in our business lines and recognizes the diversification benefits among the units. The level of assigned economic capital is a combination of the risk taken by each business line based on its actual exposures and calibrated to its own loss history where possible. Average invested capital includes economic capital and amounts we have invested in the lines of business.

As shown in Table 8, net income attributable to our lines of business increased $7.4decreased $46.2 million or 9% compared to the firstfourth quarter of 2023. Net interest revenue decreased $7.8$36.5 million primarily duelargely as a result of deposit repricing activity. Operating revenue decreased $37.4 million as the prior quarter included a pre-tax gain of $31.0 million, before related professional fees, on the sale of BOKFI. Operating expense decreased $10.2 million compared to a decline in deposit balances. Net charge-offs increased $5.8 million to $7.1 million in the second quarter of 2023. Other operating revenue increased $27.8 million. Brokerage and trading revenue increased $13.4 million, with a $9.3 million increase in trading revenue, largely due to a higher volume of U.S. agency residential mortgage-backed securities trading activity. Customer hedging revenue grew $6.1 million, primarily driven by energy customer activity. The secondfourth quarter of 2023 includedwith a gain on alternative investments of $8.1$7.9 million resulting from merchant banking activities. Fiduciarydecrease in personnel expense and asset management revenue increased $2.3 million, largely due to seasonal tax preparation fees. Operating expense increased $9.3 million over the first quarter of 2023. Personnel expense increased $7.2 million due to a combination of higher incentive compensation costs reflecting sales activity and growth in regular compensation related to our annual merit increases. Non-personnel expense increased $2.2 million led by higher mortgage banking costs. The decrease in net income attributed to Funds Management and other is largely due to adjustments made that attribute more deposit credit value to the business lines, with the offset to Funds Management and other.non-personnel expense.

Financial Condition
Securities

We maintain a securities portfolio to enhance profitability, manage interest rate risk, provide liquidity and comply with regulatory requirements. Securities are classified as trading, held for investment, or available for sale. See Note 2 to the Consolidated Financial Statements for the composition of the securities portfolio as of June 30, 2023March 31, 2024 and December 31, 2022.2023.

We hold an inventory of trading securities in support of sales to a variety of customers, including banks, corporations, insurance companies, money managers and others. Trading securities increased $3.1 billion$248 million to $5.4 billion during the secondfirst quarter of 2023 due to favorable market conditions and opportunities.2024. As discussed in the Market Risk section of this report, trading activities involve risk of loss from adverse price movement. We mitigate this risk within board-approved limits through the use of derivative contracts, short-sales and other techniques.

At June 30, 2023,March 31, 2024, the carrying value of investment (held-to-maturity) securities was $2.4$2.2 billion, including a $465$299 thousand allowance for expected credit losses, compared to $2.4$2.2 billion at MarchDecember 31, 2023 with a $497$336 thousand allowance for expected credit losses. The fair value of investment securities was $2.2$2.0 billion at June 30, 2023,March 31, 2024, a $122$73 million decrease compared to the prior quarter. Investment securities consist primarily of residential mortgage-backed securities issued by U.S. government agencies, intermediate and long-term, fixed ratefixed-rate Oklahoma and Texas municipal bonds, and taxable Texas school construction bonds.

Available for sale securities, which may be sold prior to maturity, are carried at fair value. Unrealized gains or losses, net of deferred taxes, are recorded as accumulated other comprehensive income in shareholders' equity. The amortized cost of available for sale securities totaled $12.8$13.3 billion at June 30, 2023,March 31, 2024, a $158$393 million increase compared to MarchDecember 31, 2023. At June 30, 2023,March 31, 2024, the available for sale securities portfolio consisted primarily of U.S. government agency residential mortgage-backed securities and U.S. government agency commercial mortgage-backed securities. Both residential and commercial mortgage-backed securities have credit risk from delinquency or default of the underlying loans. We mitigate this risk by primarily investing in securities issued by U.S. government agencies. Principal and interest payments on the underlying loans are fully guaranteed. Commercial mortgage-backed securities have prepayment penalties similar to commercial loans.

A primary risk of holding residential mortgage-backed securities comes from extension during periods of rising interest rates or contraction in the form of more rapid prepayments during periods of falling interest rates. We evaluate this risk through extensive modeling of risk both before making an investment and throughout the life of the security. Our best estimate of the duration of the combined residential mortgage-backed securities portfolio held in investment and available for sale securities at June 30, 2023 is 3.5was 3.4 years as of March 31, 2024, consistent with the same measure as of MarchDecember 31, 2023. Management estimates the duration extends to 3.94.0 years assuming an immediate 200 basis point upward shock. The estimated duration contracts to 2.92.4 years assuming a 200 basis point decline in the current rate environment. The duration of the total investment portfolio is 3.33.2 years, extends to 3.53.6 years in an upward shock of 200 basis points, and contracts to 3.02.6 years in a down 200 basis point shock scenario. Management also regularly monitors the impact of interest rate risk on the available for sale securities portfolio on our tangible equity ratio under various shock scenarios.

At March 31, 2024, we hold 252,233 non-transferable Class B-1 (formerly Class B) shares of Visa, Inc. in connection with a restructuring and public offering by Visa U.S.A. As a member of Visa U.S.A., we received the Class B shares based on our interest in Visa U.S.A. On January 23, 2024, Visa, Inc. stockholders approved the Exchange Offer which provides holders of Class B-1 shares an option to convert up to 50% of its Class B-1 shares to Visa Class C shares and subsequently to freely transferable Visa Class A common shares subject to certain restrictions and holding period requirements. The Exchange Offer opened on April 8, 2024 and is scheduled to expire at the end of the day on May 3, 2024. The Company tendered its Class B-1 Visa shares under the Exchange Offer and expects to monetize up to 50% of the Class B-1 shares. The per share closing price of a Visa Class A common share was $279.08 at March 31, 2024. In light of uncertainties associated with certain ongoing litigation matters involving Visa and the timing and outcome of the aforementioned proposal, the ultimate impact of this gain contingency is unknown.

Bank-Owned Life Insurance

We have approximately $411$410 million of bank-owned life insurance at June 30, 2023.March 31, 2024. This investment is expected to provide a long-term source of earnings to support existing employee benefit programs. Approximately $316 million is held in separate accounts and $95 million represents the cash surrender value of policies held in general accounts and other amounts due from various insurance companies. Our separate account holdings are invested in diversified portfolios of investment-grade fixed income securities and cash equivalents, including U.S. Treasury and Agencyagency securities, residential mortgage-backed securities, corporate debt, asset-backed and commercial mortgage-backed securities. The portfolios are managed by unaffiliated professional managers within parameters established in the portfolio's investment guidelines. The cash surrender value of certain life insurance policies is further supported by a stable value wrap, which protects against changes in the fair value of the investments. As of June 30, 2023,March 31, 2024, the fair value of investments held in separate accounts covered by the stable value wrap was approximately $287 million. Since the underlying fair value of the investments held in separate accounts at June 30, 2023March 31, 2024 was below the net book value of the investments, $27 million of cash surrender value was supported by the stable value wrap. The remaining $2 million of fair value held in separate accounts is not supported by the stable value wrap. Future rate increases may cause write-downs in the short-term. The stable value wrap is provided by an investment grade financial institution.

Commercial

Commercial loans represent loans for working capital, facilities acquisition or expansion, purchases of equipment and other needs of commercial customers primarily located within our geographical footprint. These loans are underwritten individually and represent ongoing relationships based on a thorough knowledge of the customer, the customer's industry and market. While commercial loans are generally secured by the customer's assets including real property, inventory, accounts receivable, operating equipment, interests in mineral rights and other property and may also include personal guarantees of the owners and related parties, the primary source of repayment of the loans is the ongoing cash flow from operations of the customer's business. In addition, revolving lines of credit are generally governed by a borrowing base. Inherent lending risks are centrally monitored on a continuous basis from underwriting throughout the life of the loan for compliance with commercial lending policies.

Commercial loans totaled $14.5$15.1 billion or 63 percent63% of the loan portfolio at June 30, 2023,March 31, 2024, a $317$329 million increase over MarchDecember 31, 2023, withprimarily due to growth in all commercial loan categories.general business and healthcare loans.

Approximately 71 percent70% of loans in this segment are located within our geographic footprint based on collateral location. Loans for which the collateral location is less relevant, such as unsecured loans and reserve-based energy loans, are categorized by the borrower's primary operating location. The largest concentration of loans in this segment outside of our footprint is California, totaling 5 percent5% of the segment.

Supporting the energy industry with loans to producers and other energy-related entities has been a hallmark of the Company since its founding and represents a large portion of our commercial loan portfolio. In addition, energy production and related industries have a significant impact on the economy in our primary markets. Loans collateralized by oil and gas properties are subject to a semi-annual engineering review by our internal staff of petroleum engineers. This review is used as the basis for developing the expected cash flows supporting the loan amount. The projected cash flows are discounted according to risk characteristics of the underlying oil and gas properties. Loans are evaluated to demonstrate with reasonable certainty that crude oil, natural gas and natural gas liquids can be recovered from known oil and gas reservoirs under existing economic and operating conditions at current pricing levels and with existing conventional equipment and operating methods and costs. As part of our evaluation of credit quality, we analyze rigorous stress tests over a range of commodity prices and take proactive steps to mitigate risk when appropriate.

Outstanding energy loans totaled $3.5loan balances were largely unchanged compared to the prior quarter at $3.4 billion or 15 percent14% of total loans at June 30, 2023, a $111 million increase compared to March 31, 2023.2024. Approximately $2.7$2.6 billion of energy loans were to oil and gas producers, a $12$32 million decrease compared to MarchDecember 31, 2023. The majority of this portfolio is first lien, senior secured, reserve-based lending, which we believe is the lowest risk form of energy lending. Approximately 67 percent70% of the committed production loans are secured by properties primarily producing oil, and 33 percent30% of the committed production loans are secured by properties primarily producing natural gas.

Loans to midstream oil and gas companies totaled $576$604 million at June 30, 2023,March 31, 2024, a $57$54 million increase compared to MarchDecember 31, 2023.

Unfunded energy loan commitments were $4.3 billion at June 30, 2023, growing $224March 31, 2024, a $147 million over Marchdecrease compared to December 31, 2023.

The healthcare sector of the loan portfolio totaled $4.0$4.2 billion or 17 percent18% of total loans. Healthcare loans increased $92$103 million over MarchDecember 31, 2023, primarily due to growth in loans to senior housing facilities and other medical practices. This was partially offset by a decrease in loans to hospital systems compared to the prior quarter.facilities. Healthcare sector loans consist primarily of loans for the development and operation of senior housing and care facilities including independent living, assisted living and skilled nursing. Generally we loan to borrowers with a portfolio of multiple facilities that serves to help diversify risks specific to a single facility.
The services sector of the loan portfolio totaled $3.6$3.5 billion or 15 percent15% of total loans, a $21$47 million increasedecrease compared to the prior quarter. Service sector loans consist of a large number of loans to a variety of businesses including Native American tribal and state and local governments,municipal government entities, Native American tribal casino operations, foundations and not-for-profit organizations, educational services and specialty trade contractors. Approximately $1.7$1.5 billion of the services category is made up of loans with individual balances of less than $10 million. Services sector loans are generally secured by the assets of the borrower with repayment coming from the cash flows of ongoing operations of the customer's business.

General business loans totaled $3.4$3.9 billion or 15 percent16% of total loans, an increase of $93$267 million compared to the prior quarter. General business loans consist of $2.0$2.4 billion of wholesale/retail loans and $1.4$1.5 billion of loans from other commercial industries.

We participate in shared national credits when appropriate to obtain or maintain business relationships with local customers. Shared national credits are defined by banking regulators as credits of $100 million or more and with three or more non-affiliated banks as participants. At June 30, 2023,March 31, 2024, the outstanding principal balance of these loans totaled $5.6$5.8 billion, including $2.6$2.4 billion of energy loans. Substantially all of these loans are to borrowers with local market relationships. We serve as the agent lender in approximately 22 percent21% of our shared national credits, based on dollars committed. We hold shared national credits to the same standard of analysis and perform the same level of review as internally originated credits. Our lending policies generally avoid loans in which we do not have the opportunity to maintain or achieve other business relationships with the customer. In addition to management's quarterly assessment of credit risk, banking regulators annually review a sample of shared national credits for proper risk grading.

Commercial Real Estate

Commercial real estate represents loans for the construction of buildings or other improvements to real estate and property held by borrowers for investment purposes generally within our geographical footprint. We require collateral values in excess of the loan amounts, demonstrated cash flows in excess of expected debt service requirements, equity investment in the project and a portion of the project already sold, leased or permanent financing already secured. The expected cash flows from all significant new or renewed income producing property commitments are stress tested to reflect the risks in varying interest rates, vacancy rates and rental rates. As with commercial loans, inherent lending risks are centrally monitored on a continuous basis from underwriting throughout the life of the loan for compliance with applicable lending policies.

Loans to Individuals

Loans to individuals include residential mortgage and personal loans. Residential mortgage loans provide funds for our customers to purchase or refinance their primary residence or to borrow against the equity in their home. These loans are secured by a first or second mortgage on the customer's primary residence. Personal loans consist primarily of loans to Wealth Management clients secured by the cash surrender value of insurance policies and marketable securities. Personal loans also include direct loans secured by and for the purchase of automobiles, recreational and marine equipment as well as unsecured loans. These loans are made in accordance with underwriting policies we believe to be conservative and are fully documented. Loans may be individually underwritten or credit scored based on size and other criteria. Credit scoring is assessed based on significant credit characteristics including credit history, residential and employment stability.

In general, we sell the majority of our conforming fixed-rate mortgage loan originations in the secondary market and retain the majority of our non-conforming and adjustable-rate mortgage loans. Our mortgage loan portfolio does not include payment option adjustable-rate mortgage loans or adjustable-rate mortgage loans with initial rates that are below market. Home equity loans are primarily first-lien and fully amortizing.

Residential mortgage loans guaranteed by U.S. government agencies have limited credit exposure because of the agency guarantee. This amount includes residential mortgage loans previously sold into GNMA mortgage pools that the Company may repurchase when certain defined delinquency criteria are met. Because of this repurchase right, the Company is deemed to have regained effective control over these loans and must include them on the Consolidated Balance Sheet.

Loans to individuals totaled $3.7$3.8 billion or 16% of the loan portfolio, an increase of $15.0$39 million compared to MarchDecember 31, 2023. Approximately 91 percent91% of the loans in this segment are secured by collateral located within our geographical footprint. Loans for which the collateral location is less relevant, such as unsecured loans, are categorized by the borrower's primary location.

The Company secondarily evaluates loan portfolio performance based on the primary geographical market managing the loan. Loans attributed to a geographical market may not represent the location of the borrower or the collateral. All permanent mortgage loans serviced by our mortgage banking unit and held for investment by the Company are centrally managed by the Oklahoma market.

Off-Balance Sheet Commitments

We enter into certain off-balance sheet arrangements in the normal course of business as shown in Table 14. Loan commitments may be unconditional obligations to provide financing or conditional obligations that depend on the borrower's financial condition, collateral value or other factors. Standby letters of credit are unconditional commitments to guarantee the performance of our customer to a third party. Since some of these commitments are expected to expire before being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.

We have off-balance sheet commitments related to certain residential mortgage loans sold into mortgage-backed securities as part of our mortgage banking activities. We retain off-balance sheet credit risk related to losses in excess of amounts guaranteed by the U.S. Department of Veterans Affairs ("VA").VA.

We also have off-balance sheet credit risk related to certain residential mortgage loans primarily originated under community development loan programs that were sold to a U.S. government agency with full recourse prior to 2007. We are obligated to repurchase these loans for the life of these loans in the event of foreclosure for the unpaid principal and interest at the time of foreclosure. The majority of our conforming fixed ratefixed-rate loan originations are sold in the secondary market, and we only retain repurchase obligations under standard underwriting representations and warranties.

Customer Hedging Programs
 
We offer programs that permit our customers to hedge various risks, including fluctuations in energy, cattle and other agricultural product prices, interest rates and foreign exchange rates. Each of these programs work essentially the same way. Derivative contracts are executed between the customers and the Company. Offsetting contracts are executed between the Company and selected counterparties to minimize market risk due to changes in commodity prices, interest rates or foreign exchange rates. The counterparty contracts are identical to the customer contracts except for a fixed pricing spread or a fee paid to us as compensation for administrative costs, credit risk and profit.

The customer hedging programs create credit risk for potential amounts due to the Company from our customers and from the counterparties. Customer credit risk is monitored through existing credit policies and procedures. The effects of changes in commodity prices, interest rates or foreign exchange rates are evaluated across a range of possible scenarios to determine the maximum exposure we are willing to have individually to any customer. Customers may also be required to provide cash margin or other collateral in conjunction with our credit agreements to further limit our credit risk.

Counterparty credit risk is evaluated through existing policies and procedures. This evaluation considers the total relationship between BOK Financial and each of the counterparties. Individual limits are established by management, approved by Credit Administration and reviewed by the Asset/Liability Committee. Margin collateral is required if the exposure between the Company and any counterparty exceeds established limits. Based on declines in the counterparties' credit ratings, these limits may be reduced and additional margin collateral may be required.

A deterioration of the credit standing of one or more of the customers or counterparties to these contracts may result in BOK Financial recognizing a loss as the fair value of the affected contracts may no longer move in tandem with the offsetting contracts. This occurs if the credit standing of the customer or counterparty deteriorates such that either the fair value of underlying collateral no longer supports the contract or the customer or the counterparty's ability to provide margin collateral becomes impaired. Credit losses on customer derivatives reduce brokerage and trading revenue in the Consolidated Statements of Earnings.

Derivative contracts are carried at fair value. At June 30, 2023,March 31, 2024, the net fair valuesvalue of derivative contracts, before consideration of cash margin, reported as assets under these programs totaled $538$463 million compared to $572$593 million at MarchDecember 31, 2023. At June 30, 2023,March 31, 2024, the net fair value of our derivative contracts included $327$293 million for energy contracts, $150$114 million for interest rate swaps and $61$56 million for foreign exchange contracts. The aggregate net fair value of derivative contracts, before consideration of cash margin, held under these programs reported as liabilities totaled $526$460 million at June 30, 2023March 31, 2024 and $578$587 million at MarchDecember 31, 2023.

At June 30, 2023,March 31, 2024, total derivative assets were reduced by $269$230 million of cash collateral received from counterparties and total derivative liabilities were reduced by $23$29 million of cash collateral paid to counterparties related to instruments executed with the same counterparty under a master netting agreement. Derivative contracts executed with customers may be secured by non-cash collateral in conjunction with a credit agreement with that customer, such as proven producing oil and gas properties. Access to this collateral in an event of default is reasonably assured.

A table showing the notional and fair value of derivative assets and liabilities on both a gross and net basis is presented in Note 3 to the Consolidated Financial Statements.

The fair value of derivative contracts reported as assets under these programs, net of cash margin held by the Company, by category of debtor at June 30, 2023March 31, 2024 follows in Table 15.

At June 30, 2023,March 31, 2024, our largest derivative exposure was to an exchange for $133$61 million of net derivative positions, net of cash margin.

Our customer hedging program also introduces liquidity and capital risk. We are required to provide cash margin to certain counterparties when the net negative fair value of the contracts exceeds established limits.limits which may incur additional funding costs. Also, changes in commodity prices affect the amount ofrisk-weighted assets and total assets which in turn impacts regulatory capital we are required to hold as support for the fair value of our derivative assets.ratios. These risks are modeled as part of the management of these programs. Based on current prices, a decrease in market prices down to an equivalent of $53.08$65.64 per barrel of oil would decrease the fair value of derivative assets by $32$104 million, with lending customers comprising the bulk of the assets. An increase in prices up to an equivalent of $88.20$100.70 per barrel of oil would increase the fair value of derivative assets by $580$635 million as asset values rise faster than margin paid. Liquidity requirements of this program may also be affected by our credit rating. At June 30, 2023,March 31, 2024, a decrease in our credit rating to below investment grade would increase our obligation to post cash margin on existing contracts by approximately $10 million.

The fair value of our to-be-announced residential mortgage-backed securities and interest rate swap derivative contracts is affected by changes in interest rates. Based on our assessment as of June 30, 2023,March 31, 2024, changes in interest rates would not materially impact regulatory capital or liquidity needed to support this portion of our customer derivative program.

Allowance for Loan Losses and Accrual for Off-Balance Sheet Credit Risk from Unfunded Loan Commitments
Expected credit losses on assets carried at amortized cost are recognized over their expected lives based on models that measure the probability of default and loss given default over a 12-month reasonable and supportable forecast period. Models incorporate base case, downside and upside macroeconomic variables such as real gross domestic product ("GDP")GDP growth, civilian unemployment rate, commercial real estate vacancy rates and West Texas Intermediate ("WTI")WTI oil prices on a probability weighted basis. See Note 4 to the Consolidated Financial Statements for additional discussion of methodology of allowance for loan losses.
A $17.0 million provision for credit losses was necessary for the second quarter of 2023, primarily related to higher assumed commercial real estate vacancy rates during the forecast period and overall loan portfolio growth during the quarter. The probability weighting of our base case reasonable and supportable forecast remained at 50 percent in the second quarter of 2023 as the level of uncertainty in economic forecasts remained high.
Non-pass grade loans, including loans especially mentioned, accruing substandard and nonaccruing loans, decreased by $33$14 million compared to MarchDecember 31, 2023, primarily due to2023. Non-pass grade general business loans decreased $23 million, partially offset by a decrease$12 million increase in non-pass grade general businesscommercial real estate loans. A summary of outstanding loan balances by risk grade is included in Note 4 to the Consolidated Financial Statements.

A summary of macroeconomic variables considered in developing our estimate of expectedThe provision for credit losses of $8.0 million in the first quarter of 2024 reflects continued loan growth and a stable economic forecast. The allowance for loan losses totaled $282 million or 1.17% of outstanding loans at June 30, 2023 follows:
BaseDownsideUpside
Scenario probability weighting50%40%10%
Economic outlookThe Russia-Ukraine conflict remains isolated.

There is one federal funds rate increase at the Federal Reserve Open Market ("FOMC") meeting in the third quarter of 2023, which results in a target range of 5.25 percent to 5.50 percent. There are no additional rate increases for the remainder of the forecast period.

Inflation continues to improve from the peaks experienced in 2022, reaching 3.1 percent by the second quarter of 2024. Inflation pressures cause modest declines in real household income compared to pre-pandemic levels, resulting in below-trend GDP growth.

Job openings revert to more normalized levels and overall hiring levels decline, causing the national unemployment rate to modestly increase over the next four quarters.
The Russia-Ukraine conflict remains isolated.

Higher levels of inflation force the Federal Reserve to adopt a more aggressive monetary policy compared to the base case scenario. This results in a target range of 6.00 percent to 6.25 percent by the second quarter of 2024. This pushes the United States into a recession, with a contraction in economic activity and a sharp increase in the unemployment rate.

Inflation moderates slightly from peaks in 2022 and remains elevated through the forecast horizon, ending at 3.8 percent in the second quarter of 2024.
The Russia-Ukraine conflict remains isolated.

There are no additional rate increases and the terminal range of 5.00 percent to 5.25 percent is held flat for the remainder of the forecast horizon.

Inflation continues to improve from the peaks experienced in 2022 and reaches 2.6 percent by the second quarter of 2024.

Labor force participants continue to re-enter the job market to help fill the elevated level of job openings. The increase in employment helps maintain household income above its pre-pandemic trend. This, coupled with the drawdown in savings, supports consumer spending and produces GDP growth consistent with pre-pandemic levels.
Macro-economic factors
GDP is forecasted to grow by 1.0 percent over the next 12 months.
Civilian unemployment rate of 3.8 percent in the third quarter of 2023 increases to 4.2 percent by the second quarter of 2024.
WTI oil prices are projected to generally follow the NYMEX forward curve that existed at the end of June 2023 and are expected to average $69.39 per barrel over the next 12 months.
GDP is forecasted to contract 2.0 percent over the next twelve months.
Civilian unemployment rate of 4.7 percent in the third quarter of 2023 increases to 6.1 percent in the second quarter of 2024.
WTI oil prices are projected to average $55.78 over the next 12 months, with a peak of $62.31 in the third quarter of 2023 and falling 19 percent over the following three quarters.
GDP is forecasted to grow by 1.5 percent over the next 12 months.
Civilian unemployment rate of 3.7 percent in the third quarter of 2023 increases to 3.9 percent by the second quarter of 2024.
WTI oil prices are projected to average $73.97 per barrel over the next 12 months.
March 31, 2024. Excluding residential mortgage loans guaranteed by U.S. government agencies, the allowance for loan losses was 255% of nonaccruing loans. The combined allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan commitments was $329 million or 1.36% of outstanding loans and 298% of nonaccruing loans at March 31, 2024.
The probability weighting of all scenarios in our base case reasonable and supportable forecast remained at 50 percent inunchanged compared to the second quarter of 2023 as the level of uncertainty in economic forecasts remained high.prior quarter. The sensitivity to management's economic scenario weighting may be quantified by comparing the results of weighting each economic scenario at 100%. For example, compared to a 100% Base Casebase case scenario, a 100% Downside Casedownside case would result in an additional $157$210 million in quantitative reserve, while a 100% Upside Caseupside case would result in $16$6.9 million less quantitative reserve at June 30, 2023.March 31, 2024.

A summary of macroeconomic variables considered in developing our estimate of expected credit losses at June 30, 2023.March 31, 2024 follows:
BaseDownsideUpside
Scenario probability weighting50%35%15%
Economic outlook
Geopolitical conflicts remain isolated.

Beginning in the third quarter of 2024, there is one rate cut per quarter, bringing the federal funds target range of 4.50% to 4.75% by the end of the first quarter of 2025.

Core inflation continues to improve from the previous peaks and reaches 2.5% by the first quarter of 2025.

Job openings revert to more normalized levels and overall hiring levels decline, causing the national unemployment rate to modestly increase over the next four quarters. Inflation pressures ease and help stabilize real household income. A restrictive credit environment slows economic activity and results in below-trend GDP growth.
Geopolitical conflicts remain isolated.

The Federal Reserve is forced to adopt an accommodative monetary policy compared to the base case scenario and cut the federal funds rate significantly to encourage economic activity and job creation. In total, there are ten rate cuts over the next four quarters bringing the target range to 2.75% to 3.00% by the first quarter of 2025.

Tight monetary conditions result in declines in consumer spending while a restrictive credit environment decreases private sector investment. This pushes the United States into a recession, with a contraction in economic activity and a sharp increase in the unemployment rate.
Geopolitical conflicts remain isolated.

There are four federal funds rate cuts in 2024 and one rate cut in the first quarter of 2025, bringing the target range to 4.00% to 4.25%.

Core inflation continues to improve from the previous peaks and reaches 2.2% by the first quarter of 2025.

Labor force participants continue to re-enter the job market to help fill the elevated level of job openings. The increase in employment helps maintain household income above its pre-pandemic trend. This supports consumer spending and produces GDP growth consistent with pre-pandemic levels.

Net charge-offs were primarily composed of commercial real estate loans were $4.0a $3.2 million general business loan and net charge-offs of loans to individuals were $698 thousand.a $1.3 million office loan. Net charge-offs of loans to individuals include deposit account overdraft losses.

Accrual for Off-Balance Sheet Credit Risk Associated with Mortgage Banking Activities

The accrual for off-balance sheet credit risk associated with mortgage banking activities includes consideration of credit risk related to certain residential mortgage loans sold into mortgage-backed securities in excess of amounts guaranteed by the U.S. Department of Veteran's Affairs ("VA")VA and mortgage loans originated under community development loan programs that were sold to a U.S. government agency with full recourse.

We use publicly available long-term national data to estimate total loss given default for our off-balance sheet credit risk related to losses in excess of amounts guaranteed by the VA. This result is combined with probability of default output from our mortgage servicing rights model to estimate total expected loss. Then, we estimate the VA's guarantee percentage to determine our portion of the credit risk. Qualitative adjustment may be used, if necessary.

Allowance for Credit Losses Related to Held-to-Maturity (Investment) Securities

The expected credit losses principles apply to all financial assets measured at cost, including our held-to-maturity (investment) debt securities portfolio. Our investment portfolio includes municipal and other tax-exempt securities and other debt securities. Expected credit losses for these assets are based on the probability of default and loss given default assumptions that align with similarly graded loans. Qualitative adjustment may be used, if necessary.

Nonperforming Assets

As more fully described in Note 4 to the Consolidated Financial Statements, loans are generally classified as nonaccruing when it becomes probable that we will not collect the full contractual principal and interest. Accruing renegotiated loans guaranteed by U.S. government agencies represent residential mortgage loans that have been modified in troubled debt restructurings. Interest continues to accrue based on the modified terms of the loan and loans may be sold once they become eligible according to U.S. government agency guidelines. The Company adopted FASB Accounting Standards Update No. 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures, which eliminates designation of these loans as troubled debt restructurings effective January 1, 2023. Real estate and other repossessed assets are assets acquired in partial or total forgiveness of loans. The assets are carried at the lower of cost as determined by fair value at the date of foreclosure or current fair value, less estimated selling costs.

Estimated uninsured deposits totaled $19.0$18.2 billion or 57 percent51% of our total deposits at June 30, 2023.March 31, 2024. In addition to insured deposits, we also hold $4.8$4.5 billion of collateralized deposits. Municipalities, Native American tribal governments and certain trust-related deposits are all required to be collateralized. Excluding the impact of collateralized deposits and deposits related to consolidated subsidiaries, of BOKF, NA, our uninsured and uncollateralized deposit level is $13.4$13.2 billion or 40 percent37% of total deposits at June 30, 2023.March 31, 2024.

In addition to deposits, liquidity is provided primarily by federal funds purchased, securities repurchase agreements and Federal Home Loan Banks borrowings. Federal funds purchased consist primarily of unsecured, overnight funds acquired from other financial institutions. Funds are primarily purchased from bankers' banks and Federal Home Loan Banks from across the country. The largest single source of wholesale federal funds purchased totaled $650$250 million at June 30, 2023.March 31, 2024. Securities repurchase agreements generally mature within 90 days and are secured by certain available for sale and trading securities. Federal Home Loan Banks borrowings are generally short-term and are secured by a blanket pledge of eligible collateral (generally unencumbered U.S. Treasury and agency mortgage-backed securities, 1-4 family residential mortgage loans, multifamily and other qualifying commercial real estate loans). Amounts borrowed from the Federal Home Loan Bank of Topeka averaged $5.2$6.8 billion during the quarter, compared to $4.5$7.1 billion in the firstfourth quarter of 2023.

At June 30, 2023,March 31, 2024, management estimates a total potential secured borrowing capacity of approximately $23.5$23.7 billion. This includes current available secured capacity of $19.2$20.0 billion from the use of programs available to U.S. banks from the Federal Home Loan Banks and Federal Reserve Banks and an estimated $4.3$3.7 billion of other sources that could be converted into additional secured capacity.

1 Parent Company only.
BOKF, NA also has a liability related to the repurchase of certain delinquent residential mortgage loans previously sold into GNMA mortgage pools. Interest is payable monthly at rates contractually due to investors if delinquent loans are not repurchased from the GNMA mortgage pools.
Parent Company

At June 30, 2023,March 31, 2024, cash and interest-bearing cash and cash equivalents held by the parent company totaled $204$183 million. The primary sources of liquidity for BOK Financial are cash on hand and dividends from BOKF, NA. Dividends from the bank are limited by various banking regulations to net profits, as defined, for the year plus retained profits for the two preceding years. Dividends are further restricted by minimum capital requirements. At June 30, 2023,March 31, 2024, based upon the most restrictive limitations as well as management's internal capital policy, BOKF, NA could declare up to $416$354 million of dividends. Dividend constraints may be alleviated through increases in retained earnings, capital issuances or changes in risk weighted assets. Future losses or increases in required regulatory capital at the bank could affect its ability to pay dividends to the parent company.

Our equity capital at June 30, 2023March 31, 2024 was $4.9$5.1 billion, an $11a $14 million decrease compared to MarchDecember 31, 2023. Net income less cash dividends paid increased equity $116$48 million during the secondfirst quarter of 2023.2024. Changes in interest rates resulted in a $108an $11 million decrease in accumulated other comprehensive income compared to MarchDecember 31, 2023. We also repurchased $22$52 million of common stock, excluding a one percent1% excise tax on corporate stock repurchases, during the secondfirst quarter of 2023.2024. Capital is managed to maximize long-term value to the shareholders. Factors considered in managing capital include projections of future earnings including expected benefits from lower federal income tax rates, asset growth and acquisition strategies, and regulatory and debt covenant requirements. Capital management may include subordinated debt or perpetual preferred stock issuance, share repurchase and stock and cash dividends.

On November 1, 2022, the board of directors authorized the Company to purchase up to five million common shares, subject to market conditions, securities law and other regulatory compliance limitations. As of June 30, 2023,March 31, 2024, the Company had repurchased 1,027,4773,044,844 shares under this authorization. The Company repurchased 266,000616,630 shares of common stock at an average price of $84.08$83.89 per share in the secondfirst quarter of 2023.2024. We view share buybacks opportunistically, but within the context of maintaining our strong capital position.

BOK Financial and BOKF, NA are subject to various capital requirements administered by federal agencies. Failure to meet minimum capital requirements can result in certain mandatory and possibly additional discretionary actions by regulators that could have a material impact on operations. These capital requirements include quantitative measures of assets, liabilities and off-balance sheet items. The capital standards are also subject to qualitative judgments by the regulators.

A summary of minimum capital requirements, including a capital conservation buffer follows in Table 22. A bank which falls below these levels, including the capital conservation buffer, would be subject to regulatory restrictions on capital distributions (including, but not limited to, dividends and share repurchases) and executive bonus payments.

In March 2020, in response to the impact on the financial markets by the COVID-19 pandemic, the banking agencies issued an interim final rule permitting banking organizations that implement the current expected credit loss ("CECL")CECL model the option to delay for two years an estimate of the CECL methodology's effect on regulatory capital, followed by a three-year transition period. The estimate includes the implementation date adjustment as of January 1, 2020 plus an estimate of the impact of the change for a two year period following implementation of CECL. We elected to delay the regulatory capital impact of the transition in accordance with the interim final rule. Deferral of the impact of CECL added 73 basis points to the Company's Common equity Tier 1 capital at June 30, 2023.March 31, 2024.

Explanation of Non-GAAP Measures

The tangible common equity ratio and return on average tangible common equity are primarily based on total shareholders' equity, which includes unrealized gains and losses on available for sale securities, less intangible assets and equity that do not benefit common shareholders. The adjusted tangible common equity ratio also includes unrealized gains and losses on the investment portfolio. These measures are valuable indicators of a financial institution's capital strength since they eliminate intangible assets from shareholders' equity and retain the effect of unrealized losses on securities and other components of accumulated other comprehensive income in shareholders' equity.

Pre-provision net revenue is a measure of revenue less expenses and is calculated before provision for credit losses and income tax expense. This financial measure is frequently used by investors and analysts and enables them to assess a company's ability to generate earnings to cover credit losses through a credit cycle. It also provides an additional basis for comparing the results of operations between periods by isolating the impact of the provision for credit losses, which can vary significantly between periods.

- 38 -


We believe adjusting net income and earnings per share for notable non-core items enhances comparability of results with prior periods, demonstrates the impact of significant items and provides a useful measure for determining the Company's expenses that are core to our business operations and are expected to recur over time.

The efficiency ratio measures the Company's ability to use its assets and manage its liabilities effectively in the current period. Prior to the second quarter of 2023, the efficiency ratio did not exclude amortization of intangible assets and only included tax-equivalent net interest revenue and fees and commissions as part of total revenue. All prior periods were adjusted to conform with the current methodology.

Net interest revenue and net interest margin excluding trading activities remove the effect of trading activities on these metrics allowing management and investors to assess the performance of the Company's core lending and deposit activities without the associated volatility from trading activities.
Market Risk

Market risk is a broad term for the risk of economic loss due to adverse changes in the fair value of a financial instrument. These changes may be the result of various factors, including interest rates, foreign exchange rates, commodity prices or equity prices. Financial instruments that are subject to market risk can be classified either as held for trading or held for purposes other than trading. Market risk excludes changes in fair value due to the credit of the individual issuers of financial instruments.

BOK Financial is subject to market risk primarily through the effect of changes in interest rates on both its assets held for purposes other than trading and trading assets. The effects of other changes, such as foreign exchange rates, commodity prices or equity prices do not pose significant market risk to BOK Financial. BOK Financial has no material investments in assets that are affected by changes in foreign exchange rates or equity prices. Energy and agricultural product derivative contracts, which are affected by changes in commodity prices, are matched against offsetting contracts as previously discussed.

- 39 -


The Asset/Liability Committee is responsible for managing market risk in accordance with policy limits established by the Board of Directors. The Committee monitors projected variation in net interest revenue, net income and economic value of equity due to specified changes in interest rates. These limits also set maximum levels for short-term borrowings, short-term assets, public funds and brokered deposits and establish minimum levels for un-pledgedunpledged assets, among other things. Further, the Board has approved market risk limits for fixed income trading, mortgage pipeline and mortgage servicing assets inclusive of economic hedge benefits. Exposure is measured daily and compliance is reviewed monthly. Deviations from the Board approved limits, which periodically occur throughout the reporting period, may require management to develop and execute plans to reduce exposure. These plans are subject to escalation to and approval by the Board.

The simulations used to manage market risk are based on numerous assumptions regarding the effects of changes in interest rates on the timing and extent of repricing characteristics, future cash flows and customer behavior. These assumptions are inherently uncertain and, as a result, models cannot precisely estimate or precisely predict the impact of higher or lower interest rates. Actual results will differ from simulated results due to timing, magnitude and frequency of interest rate changes, market conditions and management strategies, among other factors.

Interest Rate Risk – Other than Trading
 
As previously noted in the Net Interest Revenue section of this report, management has implemented strategies to manage the Company's balance sheet exposure to changes in interest rates over a twelve-month period within established policy limits. The effectiveness of these strategies in managing the overall interest rate risk is evaluated through the use of an asset/liability model. BOK Financial performs a sensitivity analysis to identify more dynamic interest rate risk exposures, including embedded option positions, on net interest revenue. A simulation model is used to estimate the effect of changes in interest rates on our performance across multiple interest rate scenarios. Our current internal policy limit for net interest revenue variation due to a 200 basis point parallel change in market interest rates over twelve months is a maximum decline of 6.5 percent.6.5%. Management also reviews alternative rate changes and time periods.

On March 5, 2021, the U.K. Financial Conduct Authority ("FCA") confirmed that the publication of the principal tenors of the U.S. dollar London Interbank Offered Rate ("LIBOR") will cease immediately following a final publication on June 30, 2023. Further, U.S. regulators released a joint inter-agency statement about their expectations that banks cease entering into new contracts that use USD LIBOR as a reference rate as soon as practicable and in any event by December 31, 2021.
- 39 -


The Company ceased production of new LIBOR-based exposure as of December 31, 2021 and now offers floating rate products in various alternative reference rates, with the majority of volume being observed thus far in term rate versions of the Secured Overnight Financing Rate ("SOFR"). Before the June 30, 2023 deadline, the Company mitigated its remaining LIBOR exposure, with any outstanding or committed exposure being proactively moved to an alternative rate or falling back per the terms of their contract or as per the LIBOR Act.

The Company's primary interest rate exposures include the Federal Funds rate, which affects short-term borrowings, and the prime lending rate, SOFR, which is the basis for much of the variable rate loan pricing. Additionally, residential mortgage rates directly affect the prepayment speeds for residential mortgage-backed securities and mortgage servicing rights. Derivative financial instruments and other financial instruments used for purposes other than trading are included in this simulation. In addition, the impact on the level and composition of demand deposit accounts and other core deposit balances resulting from a significant increase in short-term market interest rates and the overall interest rate environment is likely to be material. The simulation incorporates assumptions regarding the effects of such changes based on a combination of historical analysis and expected behavior. The impact of planned growth and new business activities is factored into the simulation model.

The interest rate sensitivity in Table 24 indicates management's estimation of the impact of rate changes on net interest revenue. Should deposit costs be 10 percent10% more sensitive to changes in rates, the variation in net interest revenue over the next twelve months would be (2.75) percent, or ($38.2 million)0.42% for the 200100 basis point increasedecrease scenario. Alternatively, should deposit funding costs be 10 percent10% less sensitive to changes in rates, the variation in net interest revenue over the next twelve months would be (0.53) percent,(0.80)%, or ($7.410.4 million) for the 100 basis point decrease scenario. Additionally, in a flattening yield curve scenario where long-term rates increase by 100 basis points and short-term rates increase by 200 basis point increase scenario.points, net interest revenue would decrease approximately 4.78%, or $62 million.

BOK Financial is also subjected to market risk through changes in the fair value of mortgage servicing rights. Changes in the fair value of mortgage servicing rights are highly dependent on changes in primary mortgage rates offered to borrowers, intermediate-term interest rates that affect the value of custodial funds, and assumptions about servicing revenues, servicing costs and discount rates. As primary mortgage rates increase, prepayment speeds slow and the value of our mortgage servicing rights increases. As primary mortgage rates fall, prepayment speeds increase and the value of our mortgage servicing rights decreases.

We maintain a portfolio of financial instruments which may include debt securities issued by the U.S. government or its agencies and interest rate derivative contracts, held as an economic hedge of the changes in the fair value of our mortgage servicing rights. Composition of this portfolio will change based on our assessment of market risk. Changes in the fair value of residential mortgage-backed securities are highly dependent on changes in secondary mortgage rates required by investors, and interest rate derivative contracts are highly dependent on changes in other market interest rates. While primary and secondary mortgage rates generally move in the same direction, the spread between them may widen and narrow due to market conditions and government intervention. Changes in the forward-looking spread between the primary and secondary rates can cause significant earnings volatility.

Management performs a stress test to measure market risk due to changes in interest rates inherent in its MSR portfolio and hedges. The stress test shocks applicable interest rates up and down 50 basis points and calculates an estimated change in fair value, net of economic hedging activity, that may result. The Board has approved a $20 million market risk limit for mortgage servicing rights, net of economic hedges.

Trading Activities

The Company bears market risk by originating residential mortgages held for sale ("RMHFS").RMHFS. RMHFS are generally outstanding for 60 to 90 days, which represents the typical period from commitment to originate a loan to sale of the closed loan to an investor. Primary mortgage interest rate changes during this period affect the value of RMHFS commitments and loans. We use forward sale contracts to mitigate market risk on all closed mortgage loans held for sale and on an estimate of mortgage loan commitments that are expected to result in closed loans.

A variety of methods are used to monitor market risk of mortgage origination activities. These methods include daily marking of all positions to market value, independent verification of inventory pricing, and revenue sensitivity limits.

Management performs a stress test to measure market risk due to changes in interest rates inherent in the mortgage production pipeline. The stress test shocks applicable interest rates up and down 50 basis points and calculates an estimated change in fair value, net of economic hedging activity that may result. The Board has approved a $7 million market risk limit for the mortgage production pipeline, net of forward sale contracts.

BOK Financial enters into trading activities both as an intermediary for customers and for its own account. As an intermediary, we take positions in securities, generally residential mortgage-backed securities, government agency securities and municipal bonds. These securities are purchased for resale to customers, which include individuals, corporations, foundations and financial institutions. On a limited basis, we may also take trading positions in U.S. Treasury securities, residential mortgage-backed securities, and municipal bonds to enhance returns on securities portfolios. Both of these activities involve interest rate risk, liquidity risk and price risk.

A variety of methods are used to monitor and manage the market risk of trading activities. These methods include daily marking of all positions to market value, independent verification of inventory pricing, and position limits for each trading activity. Risk management tools include Value at Risk ("VaR"),VaR, stress testing and sensitivity analysis. Economic hedges in either the futures or cash markets may be used to reduce the risk associated with some trading programs. Basis Riskrisk can result when trading asset values and the instruments used to hedge them move at different rates.

VaR measures the potential loss of a given position or portfolio of positions at a specified confidence level and time horizon. BOK Financial utilizes a historical VaR methodology to measure and aggregate risks across its covered trading positions. For Market Risk Rule purposes, the Company calculates VaR using a historical simulation approach and measures the potential trading losses using a 10-day holding period and a 99% confidence level.

- 41 -


Due to inherent limitations of the VaR methodology, including its reliance on past market behavior, which might not be indicative of future market performance, VaR is only one of several tools used to measure and manage market risk. Other tools used to actively manage market risk include stress testing ("Stressed VaR")(SVaR) and sensitivity analysis.

Stressed VaRSVaR is calculated using the same internal models as used for the VaR-based measure. Stressed VaRSVaR is calculated over a ten-day holding period at a one-tail, 99% confidence level and employs a historical simulation approach based on a continuous twelve-month historical window selected to reflect a period of significant financial stress for the Company's trading portfolio.

The trading portfolio's VaR and Stressed VaRSVaR profiles are influenced by a variety of factors, including the size and composition of the portfolio, market volatility, and the correlation between different positions. A portfolio of trading positions is typically less risky than the sum of the risk from each of the individual sub-portfolios because, under normal market conditions, risk within each category partially offsets the exposure to other risk categories. Table 27 below summarizes certain VaR and Stressed VaRSVaR based measures for the three months ended June 30, 2023, March 31, 2024, December 31, 2023, June 30, 2022 and Mar.March 31, 2022.2023.

The Company monitors the accuracy of internal VaR models and modeling processes by back-testing model performance. The Company updates historical data used by the VaR model on a regular basis, and model validators independent of business lines perform regular validations to access model input, processing, and reporting components. These models are required to be independently validated and approved prior to implementation.

Limit Structure

Beyond VaR and SVaR described above, Management also performs a sensitivity analysis to measure market risk from changes in interest rates on its trading portfolio. Applicable interest rates are shocked up and down 50 basis points, calculating an estimated change in fair value, net of economic hedging activity that may result. The Board has approved an $8$11 million market risk limit for the trading portfolio, net of economic hedges.

Controls and Procedures
 
As required by Rule 13a-15(b), BOK Financial's management, including the Chief Executive Officer and Chief Financial Officer, conducted an evaluation as of the end of the period covered by their reports, of the effectiveness of the Company's disclosure controls and procedures as defined in Exchange Act Rule 13a-15(e). Based on that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the disclosure controls and procedures were effective as of the end of the period covered by this report. As required by Rule 13a-15(d), BOK Financial's management, including the Chief Executive Officer and Chief Financial Officer, also conducted an evaluation of the Company's internal controls over financial reporting to determine whether any changes occurred during the quarter covered by this report that have materially affected, or are reasonably likely to materially affect, the Company's internal controls over financial reporting. Based on that evaluation, there has been no such change during the quarter covered by this report.
Forward-Looking Statements

This report contains forward-looking statements that are based on management's beliefs, assumptions, current expectations, estimates and projections about BOK Financial Corporation, the financial services industry, and the economy generally and the related responses of the government, consumers, and others, on our business, financial condition and results of operations. Words such as "anticipates," "believes," "estimates," "expects," "forecasts," "plans," "outlook," "projects," "will," "intends," variations of such words and similar expressions are intended to identify such forward-looking statements. Management judgments relating to and discussion of the provision and allowance for credit losses, allowance for uncertain tax positions, accruals for loss contingencies and valuation of mortgage servicing rights involve judgments as to expected events and are inherently forward-looking statements. Assessments that acquisitions and growth endeavors will be profitable are necessary statements of belief as to the outcome of future events based in part on information provided by others which BOK Financial has not independently verified. These various forward-looking statements are not guarantees of future performance and involve certain risks, uncertainties, and assumptions which are difficult to predict with regard to timing, extent, likelihood and degree of occurrence. Therefore, actual results and outcomes may materially differ from what is expected, implied or forecasted in such forward-looking statements. Internal and external factors that might cause such a difference include, but are not limited to changes in government, consumer or business responses to changes in commodity prices, interest rates and interest rate relationships, inflation, demand for products and services, the degree of competition by traditional and nontraditional competitors, changes in banking regulations, tax laws, prices, levies and assessments, the impact of technological advances, and trends in customer behavior as well as their ability to repay loans. BOK Financial and its affiliates undertake no obligation to update, amend or clarify forward-looking statements, whether as a result of new information, future events, or otherwise.

Annualized, pro forma, projected and estimated numbers are used for illustrative purpose only, are not forecasts and may not reflect actual results.

In this report we may sometimes use non-GAAP financial measures. Please note that although non-GAAP financial measures provide useful insight to analysts, investors and regulators, they should not be considered in isolation or relied upon as a substitute for analysis using GAAP measures. If applicable, we provide GAAP reconciliations for non-GAAP financial measures.

Notes to Consolidated Financial Statements (Unaudited)

(1) Significant Accounting Policies

Basis of Presentation

The accompanying unaudited consolidated financial statements of BOK Financial Corporation ("BOK Financial" or "the Company") have been prepared in accordance with accounting principles for interim financial information generally accepted in the United States and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included.

The unaudited consolidated financial statements include accounts of BOK Financial and its subsidiaries, principally BOKF, NA, ("the Bank"), BOK Financial Securities, Inc., and BOK Financial Private Wealth, Inc. Operating divisions of the Bank include Bank of Albuquerque, Bank of Oklahoma, Bank of Texas, BOK Financial in Arizona, Arkansas, Colorado and Kansas/Missouri, BOK Financial Mortgage and the TransFund electronic funds network.

Certain reclassifications have been made to conform to the current period presentation.

The financial information should be read in conjunction with BOK Financial's 20222023 Form 10-K filed with the Securities and Exchange Commission, which contains audited financial statements. Amounts presented as of December 31, 20222023 have been derived from the audited financial statements included in BOK Financial's 20222023 Form 10-K but do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. Operating results for the six-monththree-month period ended June 30, 2023March 31, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023.2024.

Newly Adopted and Pending Accounting Policies

Financial Accounting Standards Board ("FASB")

FASB Accounting Standards Update No. 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures ("ASU 2022-02")

On March 31, 2022, the FASB issued ASU 2022-02 which eliminates the accounting guidance on troubled debt restructurings ("TDRs") for creditors in ASC 310-40, while also no longer requiring an entity to consider renewals, modifications, and extensions that result from reasonably expected TDRs in their calculation of the allowance for credit losses. For receivables for which there has been a modification in their contractual cash flows, ASU 2022-02 requires disclosure, by class of financing receivable, of the types of modifications, the financial effects of those modifications, and the performance of these modified receivables, along with receivables that had a payment default during the current period and had modifications to the contractual cash flows within 12 months prior to the default. Further, ASU 2022-02 requires entities to disclose gross write-offs recorded in the current period by year of origination in the vintage disclosures on a year-to-date basis. ASU 2022-02 was effective for the Company January 1, 2023. Amendments related to TDR recognition and measurement and vintage disclosures were applied prospectively and are included in Note 4 to the consolidated financial statements. Adoption of this standard did not have a material effect on the Company's financial condition or results of operations.

FASB Accounting Standards Update No. 2023-01, Leases (Topic 842): Common Control Arrangements ("ASU 2023-01")

On March 27, 2023, the FASB issued ASU 2023-01 which, in part, amends the accounting for leasehold improvement in common-control arrangements. Under previous guidance, a lessee is generally required to amortize leasehold improvements that it owns over the shorter of the useful life of those improvements or the lease term. However, due to the nature of leasehold improvements made under leases between entities under common control, ASU 2023-01 requires a lessee in a common-control arrangement to amortize such leasehold improvements that it owns over the improvements' useful life to the common control group, regardless of the lease term. ASU 2023-01 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Adoption of ASU 2023-01 did not have a material impact on the Company's financial statements.

FASB ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures

The FASB issued ASU 2023-07 on November 27, 2023 which is intended to improve reportable segment disclosure requirements. Under previous guidance, while entities were required to disclose segment revenue and measure of profit or loss, there has been limited disclosure around the reporting of segment expenses. In addition to enhanced disclosures about significant segment expenses, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The purpose of the amendments is to enable investors to better understand an entity’s overall performance and assess potential future cash flows. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company is evaluating the requirements of the expanded segment disclosures but does not expect the additional disclosures to have a material impact on the reported segment information.


- 49 -


FASB ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures

The FASB issued ASU 2023-09 on December 14, 2023 which amends income tax disclosures to provide information to better assess how an entity’s operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. The new guidance requires the entity to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. The Company is currently assessing the impact ASU 2023-09 will have on its income tax disclosures.

FASB ASU 2024-01, Compensation—Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards

The FASB issued ASU 2024-01 on March 21, 2024 which provides illustrative guidance to help entities determine whether profits interest and similar awards should be accounted for as share-based payment arrangements within the scope of Topic 718, Compensation—Stock Compensation. The ASU is effective for annual periods beginning after December 15, 2024, including interim periods within those periods. Adoption of ASU 2024-01 is not expected to have a material impact on the Company's financial statements.

- 51 -


FASB Accounting Standards Update No. 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method ("ASU 2023-02")

On March 29, 2023, the FASB issued ASU 2023-02 which amends previous guidance to allow entities to account for qualifying tax equity investments using the proportional amortization method regardless of the program giving rise to the related income tax credits, as opposed to only being allowed to apply this method to qualifying tax equity investments in low-income housing tax credit structures as was the case under previous guidance. ASU 2023-02 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. On June 30, 2023, the Company early adopted ASU 2023-02 as of January 1, 2023 using the modified retrospective approach, which did not have a material impact on the Company's financial statements. The Company transitioned from the equity method of accounting and began applying the proportional amortization method of accounting to its qualifying new markets tax credit and historic tax credit investments in addition to its low income housing tax credit partnerships already subject to the proportional amortization method.

Fair Value Option Securities
 
Fair value option securities represent securities which the Company has elected to carry at fair value and are separately identified on the Consolidated Balance Sheets. Changes in the fair value are recognized in earnings as they occur. Certain securities are held as an economic hedge of the mortgage servicing rights. 

The fair value and net unrealized gain (loss) included in fair value option securities is as follows (in thousands):

(3) Derivatives
 
Derivative instruments may be used by the Company as part of its internal risk management programs or may be offered to customers. All derivative instruments are carried at fair value, and changes in fair value are reported in earnings as they occur. Credit risk is also considered in determining fair value. Deterioration in the credit rating of customer or other counterparties reduce the fair value of asset contracts. Deterioration of our credit rating could decrease the fair value of our derivative liabilities.

When bilateral netting agreements or similar arrangements exist between the Company and its counterparties that create a single legal claim or obligation to pay or receive the net amount in settlement of the individual derivative contracts, the Company reports derivative assets and liabilities on a net by derivative contract type by counterparty basis.

Derivative contracts may require the Company to provide or receive cash margin as collateral for derivative assets and liabilities. Derivative assets and liabilities are reported net of cash margin when certain conditions are met. In addition, derivative contracts executed with customers under Customer Risk Management Programs may be secured by non-cash collateral in conjunction with a credit agreement with that customer. Access to collateral in the event of default is reasonably assured.
 
None of these derivative contracts have been designated as hedging instruments for accounting purposes.

Customer Risk Management Programs
 
BOK Financial offers programs to permit its customers to manage various risks, including fluctuations in energy, cattle and other agricultural products, interest rates and foreign exchange rates with derivative contracts. Customers may also manage interest rate risk through interest rate swaps used by borrowers to modify interest rate terms of their loans. Derivative contracts are executed between the customers and BOK Financial. Offsetting contracts are executed between BOK Financial and other selected counterparties to minimize the risk of changes in commodity prices, interest rates or foreign exchange rates. The counterparty contracts are identical to customer contracts, except for a fixed pricing spread or fee paid to BOK Financial as profit and compensation for administrative costs and credit risk which is recognized over the life of the contracts and included in Other operating revenue – Brokerage and trading revenue in the Consolidated Statements of Earnings.
 
Trading

BOK Financial may offer derivative instruments such as to-be-announced securities to mortgage banking customers to enable them to manage their market risk or to mitigate the Company's market risk of holding trading securities. Changes in the fair value of derivative instruments for trading purposes or used to mitigate the market risk of holding trading securities are included in Other operating revenue – Brokerage and trading revenue.revenue in the Consolidated Statements of Earnings.

- 5755 -


Internal Risk Management Programs
 
BOK Financial may use derivative contracts in managing its interest rate sensitivity, as part of its economic hedge of the change in the fair value of mortgage servicing rights. Changes in the fair value of derivative instruments used in managing interest rate sensitivity and as part of the economic hedge of changes in the fair value of mortgage servicing rights are included in Other operating revenue – Gain (loss) on derivatives, net in the Consolidated Statements of Earnings.

As discussed in Note 5, certain derivative contracts not designated as hedging instruments related to mortgage loan commitments and forward sales contracts are included in Residential mortgage loans held for sale on the Consolidated Balance Sheets. See Note 5 for additional discussion of notional, fair value and impact on earnings of these contracts.

(4) Loans and Allowances for Credit Losses

Loans

Loans are either secured or unsecured based on the type of loan and the financial condition of the borrower. Repayment is generally expected from cash flow or proceeds from the sale of selected assets of the borrower. BOK Financial is exposed to risk of loss on loans due to the borrower's difficulties, which may arise from any number of factors, including problems within the respective industry or local economic conditions. Access to collateral, in the event of borrower default, is reasonably assured through adherence to applicable lending laws and through sound lending standards and credit review procedures. Accounting policies for all loans, excluding residential mortgage loans guaranteed by U.S. government agencies, are as follows.

- 60 -


Interest is accrued at the applicable interest rate on the principal amount outstanding. Loans are placed on nonaccruing status when, in the opinion of management, full collection of principal or interest is uncertain. Internally risk graded loans are individually evaluated for nonaccruing status quarterly. Non-risk graded loans are generally placed on nonaccruing status when more than 90 days past due or within 60 days of being notified of the borrower's bankruptcy filing. Interest previously accrued but not collected is charged against interest income when the loan is placed on nonaccruing status. Accrued but not paid interest receivable is included in Receivables in the Consolidated Balance Sheets. Payments on nonaccruing loans are applied to principal or recognized as interest income, according to management's judgment as to the collectability of principal. Loans may be returned to accruing status when, in the opinion of management, full collection of principal and interest, including principal previously charged off, is probable based on improvements in the borrower's financial condition or a sustained period of performance.

For loans acquired with no evidence of credit deterioration, discounts are accreted on either an individual basis for loans with unique characteristics or on a pool basis for groups of homogeneous loans. Accretion is discontinued when a loan with an individually attributed discount is placed on nonaccruing status.

Modifications of loans to existing borrowers generally consist of interest rate reductions, extension of payment terms, or a combination of these. Modifications may arise either voluntarily through negotiations with the borrower or involuntarily through court order. Payment deferrals up to six months are generally considered to be short-term modifications. Generally, principal and accrued but unpaid interest isare not voluntarily forgiven. A change to the allowance for credit losses is generally not recorded upon modification because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance methodology.

- 58 -


Performing loans may be renewed under the current collateral value, debt service ratio and other underwriting standards. Nonaccruing loans may be renewed and will remain classified as nonaccruing. 

Occasionally, loans, other than residential mortgage loans, may be held for sale in order to manage credit concentration. These loans are carried at the lower of cost or fair value with gains or losses recognized in Other gains (losses), net in the Consolidated Statements of Earnings.

All loans are charged off when the loan balance or a portion of the loan balance is no longer supported by the paying capacity of the borrower or when the required cash flow is reduced in a modification. The charge-off amount is determined through a quarterly evaluation of available cash resources and collateral values. Internally risk graded loans are evaluated quarterly, and charge-offs are taken in the quarter in which the loss is identified. Non-risk graded loans that are past due between 60 days and 180 days, based on the loan product type, are charged off. Loans to borrowers whose personal obligation has been discharged through Chapter 7 bankruptcy proceedings are charged off within 60 days of notice of the bankruptcy filing, regardless of payment status.

Loan origination and commitment fees and direct loan acquisition and origination costs are deferred and amortized as an adjustment to yield over the life of the loan or over the commitment period, as applicable. Amortization does not anticipate loan prepayments. Net unamortized fees are recognized in full at time of payoff.

Qualifying residential mortgage loans guaranteed by U.S. government agencies have been sold into GNMA pools. Under certain performance conditions specified in government programs, the Company may have the right, but not the obligation to repurchase loans from GNMA pools. These loans no longer qualify for sale accounting and are recognized in the Consolidated Balance Sheets. We do not expect to receive all principal and interest based on the loan's contractual terms. A portion of the principal balance continues to be guaranteed; however, interest accrues at a curtailed rate as specified in the programs. The carrying value of these loans is reduced based on an estimate of the expected cash flows discounted at the original note rate plus a liquidity spread. Guaranteed loans may be modified in accordance with U.S. government agency guidelines. Interest continues to accrue based on the modified rate. Guaranteed loans may either be resold into GNMA pools after a performance period specified by the programs or foreclosed and conveyed to the guarantors.

Loans are disaggregated into portfolio segments and further disaggregated into classes. The portfolio segment is the level at which the Company develops and documents a systematic method for determining its allowance for credit losses. Classes are a further disaggregation of portfolio segments based on the risk characteristics of the loans and the Company's method for monitoring and assessing credit risk.

Credit Commitments
 
Commitments to extend credit are agreements to lend to a customer as long as there is no violation of conditions established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. At June 30, 2023,March 31, 2024, outstanding commitments totaled $15.0$14.4 billion. Because some commitments are expected to expire before being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. BOK Financial uses the same credit policies in making commitments as it does loans.

The amount of collateral obtained, if deemed necessary, is based upon management's credit evaluation of the borrower.

- 59 -


Standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. Because the credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loan commitments, BOK Financial uses the same credit policies in evaluating the creditworthiness of the customer. Additionally, BOK Financial uses the same evaluation process in obtaining collateral on standby letters of credit as it does for loan commitments. The term of these standby letters of credit is defined in each commitment and typically corresponds with the underlying loan commitment. At June 30, 2023,March 31, 2024, outstanding standby letters of credit totaled $722$734 million. 

Allowances for Credit Losses and Accrual for Off-balance Sheet Credit Risk from Unfunded Loans Commitments

The allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan commitments represent the portion of the amortized cost basis of loans that we do not expect to collect over the asset's contractual life, considering past events, current conditions, and reasonable and supportable forecasts of future economic conditions. The appropriateness of the allowance for credit losses, including industry and product adjustments, is assessed quarterly by a senior management Allowance Committee. This review is based on an on-goingongoing evaluation of the estimated expected credit losses in the portfolio and on unused commitments to provide financing. A well-documented methodology has been developed and is applied by an independent Credit Administration department to assure consistency across the Company.

The allowance for loan losses consists of specific allowances attributed to certain individual loans, generally nonaccruing loans, with dissimilar risk characteristics that have not yet been charged down to amounts we expect to recover and general allowances for estimated credit losses on pools of loans that share similar risk characteristics.

When full collection of principal or interest is uncertain, the loan's risk characteristics have changed, and we exclude the loan from the general allowance pool, typically designating it as nonaccruing. For these loans, a specific allowance reflects the expected credit loss.

- 62 -


We measure specific allowances for loans excluded from the general allowance pool by an evaluation of estimated future cash flows discounted at the loan's initial effective interest rate or the fair value of collateral for certain collateral dependent loans. For a non-collateral dependent loan, the specific allowance is the amount by which the loan's amortized cost basis exceeds its net realizable value. We measure the specific allowance for collateral dependent loans as the amount by which the loan's amortized cost basis exceeds its fair value. When repayment is expected to be provided substantially through the sale of collateral, we deduct estimated selling costs from the collateral's fair value. Generally, for real property held as collateral for loans, third partythird-party appraisals that conform to Uniform Standards of Professional Appraisal Practice serve as the basis for the fair value of real property held as collateral. These appraised values are on an "as-is" basis and generally are not adjusted by the Company. We obtain updated appraisals at least annually or more frequently if market conditions indicate collateral values may have declined. For energy loans, our internal staff of engineers generally determines collateral value of mineral rights based on projected cash flows from proven oil and gas reserves under existing economic and operating conditions. For real property held as collateral for other loans, third partythird-party appraisals that conform to Uniform Standards of Professional Appraisal Practice generally serve as the basis for the fair value. These appraised values are on an "as-is" basis and generally are not adjusted by the Company. We obtain updated appraisals at least annually or more frequently if market conditions indicate collateral values may have declined. Our special assets staff generally determines the value of other collateral based on projected liquidation cash flows under current market conditions. We evaluate collateral values and available cash resources quarterly. Historical statistics may be used to estimate specific allowances in limited situations, such as when a collateral dependent loan is removed from the general allowance pool near the end of a reporting period until an appraisal of collateral value is received or a full assessment of future cash flows is completed.

General allowances estimate expected credit losses on pools of loans sharing similar risk characteristics that are expected to occur over the loan's estimated remaining life. The loan's estimated remaining life represents the contractual term adjusted for amortization, estimates of prepayments, and borrower-owned extension options. Approximately 90 percent90% of the committed dollars in the loan portfolio is risk graded loans with general allowance model inputs that include probability of default, loss given default, and exposure at default. Probability of default is based on the migration of loans from performing to nonperforming using historical life of loan analysis periods. Loss given default is based on the aggregate losses incurred, net of estimated recoveries. Exposure at default represents an estimate of the outstanding amount of credit exposure at the time a default may occur.

Charge-off migration is used to calculate the general allowance for the majority of non-risk graded loans to individuals. The expected credit loss on less than 10 percent10% of the committed dollars in the portfolio is calculated using charge-off migration.

- 60 -


The expected credit loss on approximately 1 percent1% of the committed dollars in the portfolio is calculated using a non-modeled approach. Specifically, the calculation applies a long-term net charge-off rate to the loan balances, adjusted for the weighted average remaining maturity of each portfolio.
    
In estimating the expected credit losses for general allowances on performing risk-graded loans, each portfolio class is assigned relevant economic loss drivers which best explain variations in portfolio net loss rates. The probability of default estimates for each portfolio class are adjusted for current and forecasted economic conditions. The result is applied to the exposure at default and loss given default to calculate the lifetime expected credit loss estimate. Selection of relevant economic loss drivers is re-evaluated periodically and involves statistical analysis as well as management judgment. The unemployment rate factors significantly in the allowance for loan losses calculation, affecting commercial and loans to individuals segments. Other primary factors impacting the commercial portfolio include BBB corporate spreads, real gross domestic product growth rate, and energy commodity prices. The primary commercial real estate variables are vacancy rate and BBB corporate spreads. In addition to the unemployment rate, the forecast for loans to individuals is tied to a home price index. The forecasts may include regional economic factors when localized conditions diverge from national conditions.

An Economic Forecast Committee, consisting of senior management with members largely independent of the allowance process develops a twelve-month forward-looking forecast for the relevant economic loss drivers. Management develops these forecasts based on external data as well as a view of future economic conditions which may include adjustments for regional conditions. The forecast includes three economic scenarios and probability weights for each scenario. The base forecast represents management's view of the most likely outcome, while the downside forecast reflects reasonably possible worsening economic conditions, and the upside forecast projects reasonably possible improving conditions.

At the end of the one-year reasonable and supportable forecast period, we transition from shorter-term expected losses to long-term loss averages for the loan's estimated remaining life. The difference between short-term loss forecasts and long-term loss averages is run-off over the reversion horizon, up to three years, depending on the forecasted economic scenarios.

- 63 -


General allowances also consider the estimated impact of factors that are not captured in the modeled results or historical experience. These factors may increase or decrease modeled results by amounts determined by the Allowance Committee. Factors not captured in modeled results or historical experience may include for example, new lines of business, market conditions that have not been previously encountered, observed changes in credit risk that are not yet reflected in macro-economic factors, or economic conditions that impact loss given default assumptions.

The accrual for off-balance sheet credit risk is maintained at a level that is appropriate to cover estimated losses associated with credit instruments that are not currently recognized as assets such as loan commitments, standby letters of credit or guarantees that are not unconditionally cancelable by the bank. This accrual is included in other liabilities in the Consolidated Balance Sheets. The appropriateness of the accrual is determined in the same manner as the allowance for loan losses, with the added consideration of commitment usage over the remaining life for those loans that the bank can not unconditionally cancel.

A provision for credit losses is charged against or credited to earnings in amounts necessary to maintain an appropriate Allowance for Credit Losses. Recoveries of loans previously charged off are added to the allowance when received.

Credit Quality Indicators

The Company utilizes risk grading as primary credit quality indicators as it influences the probability of default which is a key attribute in the expected credit losses calculation. Substantially all commercial as well as commercial real estate loans and certain loans to individuals are risk graded based on a quarterly evaluation of the borrowers' ability to repay the loans. Certain commercial loans and most loans to individuals are small, homogeneous pools that are not risk-graded. The credit quality of these loans is based on past due days in accordance with regulatory guidelines.

We have included in the credit quality indicator "pass" loans that are in compliance with the original terms of the agreement and currently exhibit no factors that cause management to have doubts about the borrowers' ability to remain in compliance with the original terms of the agreement, which is consistent with the regulatory guideline of "pass". This also includes past due residential mortgages that are guaranteed by agencies of the U.S. government that continue to accrue interest based on criteria of the guarantors' programs.

Other loans especially mentioned ("Special Mention") are currently performing in compliance with the original terms of the agreement but may have a potential weakness that deserves management's close attention, consistent with regulatory guidelines. Non-graded loans 30 to 59 days past due are categorized as Special Mention.

The risk grading process identifies certain loans that have a well-defined weakness (for example, inadequate debt service coverage or liquidity or marginal capitalization; repayment may depend on collateral or other risk mitigation) that may jeopardize liquidation of the debt and represent a greater risk due to deterioration in the financial condition of the borrower. This is consistent with the regulatory guideline for "substandard". Because the borrowers are still performing in accordance with the original terms of the loan agreements, these loans remain on accruing status. Non-graded loans 60 to 89 days past due are categorized as Accruing Substandard.

Nonaccruing loans represent loans for which full collection of principal and interest is uncertain. This includes certain loans considered "substandard" and all loans considered "doubtful" by regulatory guidelines. Non-graded loans 90 or more days past due are categorized as Nonaccrual.

Probability of default is lowest for pass graded loans and increases for each credit quality indicator, Special Mention, and Accruing Substandard.

Vintage represents the year of origination, except for revolving loans which are considered in aggregate. Loans that were once revolving but have converted to term loans without additional underwriting appear in a separate vintage column.

(5) Mortgage Banking Activities

Residential Mortgage Loan Production

The Company originates, markets and services conventional and government-sponsored residential mortgage loans. Generally, conforming fixed ratefixed-rate residential mortgage loans are held for sale in the secondary market, and non-conforming and adjustable-rate residential mortgage loans are retained for investment. Residential mortgage loans originated for sale by the Company are carried at fair value based on sales commitments and market quotes. Changes in the fair value of mortgage loans held for sale are included in Other operating revenue – Mortgage banking revenue. Residential mortgage loans held for sale also includes the fair value of residential mortgage loan commitments and forward sales commitments, which are considered derivative contracts that have not been designated as hedging instruments for accounting purposes. The volume of mortgage loans originated for sale and secondary market prices are the primary drivers of originating and marketing revenue.

Residential mortgage loan commitments are generally outstanding for 60 to 90 days, which represents the typical period from commitment to originate a residential mortgage loan to when the closed loan is sold to an investor. Residential mortgage loan commitments are subject to both credit and interest rate risk. Credit risk is managed through underwriting policies and procedures, including collateral requirements, which are generally accepted by the secondary loan markets. Exposure to interest rate fluctuations is partially managed through forward sales of residential mortgage-backed securities and forward sales contracts. These latter contracts set the price for loans that will be delivered in the next 60 to 90 days.

The unpaid principal balance of residential mortgage loans held for sale, notional amounts of derivative contracts related to residential mortgage loan commitments and forward contract sales and their related fair values included in Mortgage loans held for sale on the Consolidated Balance Sheets were (in thousands):

Changes in the fair value of mortgage servicing rights due to market assumption changes are included in Other operating revenue in the Consolidated Statements of Earnings. Changes in fair value due to principal payments are included in Mortgage banking costs. 

Mortgage servicing rights are not traded in active markets. Fair value is determined by discounting the projected net cash flows. Significant market assumptions used to determine fair value based on significant unobservable inputs were as follows:

Changes in primary residential mortgage interest rates directly affect the prepayment speeds used in valuing our mortgage servicing rights. A separate third partythird-party model is used to estimate prepayment speeds based on interest rates, housing turnover rates, estimated loan curtailment, anticipated defaults and other relevant factors. The prepayment model is updated periodically for changes in market conditions and adjusted to better correlate with actual performance of BOK Financial's servicing portfolio.

(6) Commitments and Contingent Liabilities

Litigation Contingencies

As a member of Visa, BOK Financial is obligated for a proportionate share of certain covered litigation losses incurred by Visa under a retrospective responsibility plan. A contingent liability was recognized for the Company’s share of Visa’s covered litigation liabilities. Visa funded an escrow account to cover litigation claims, including covered litigation losses under the retrospective responsibility plan, with proceeds from its initial public offering in 2008 and from available cash.

BOK Financial currently owns 252,233 Visa Class B-1 shares (formerly Class B). On June 24, 2015, January 23, 2024, Visa, Inc. stockholders approved an option to convert up to 50% of our Class B-1 shares to Visa Class C shares and subsequently to freely transferable Visa Class A common shares (the "Exchange Offer") subject to holding periods and certain other conditions contained in the Exchange Offer. The Exchange Offer opened on April 8, 2024, and is scheduled to expire at the end of the day on May 3, 2024. The Company tendered its Class B-1 Visa shares under the Exchange Offer and expects to monetize up to 50% of the Class B-1 shares. Conversion of Class B-1 shares would not reduce our proportionate share of the covered litigation losses which may dilute our remaining Class B shares if the escrow fund is not adequate to cover final litigation costs.

BOKF, NA received a complaint that an employee had colluded with a bond issuer and an individual in misusing revenues pledgedis subject to litigation related to its role as Indenture Trustee for multiple municipal bonds forto which BOKF, NA servedChristopher Brogdon acted as trustee underborrower. The principal amount of the bond indenture. The Company conducted an investigation and concluded that employeesbonds remaining unpaid at this time is $33 million. Mr. Brogdon is obligated to pay the bonds in onefull by virtue of its Corporate Trust offices had, with respect to a single groupJudgment in the USDC of affiliated bond issuances, violated Company policies and procedures. The relationship manager was terminated. The Company reported the circumstances to, and cooperated with an investigation by,New Jersey which allows the Securities and Exchange Commission ("SEC"). On September 7, 2016,to pursue collection to satisfy the Judgment, which the SEC continues to pursue. The remaining cases are (i) Robert Elliot & Marvin Loeb on behalf of a class of persons purchasing bonds in multiple municipal bond issuances v. BOKF, NA, agreed to,USDC District of New Jersey, Case No. 2:16-cv-05218-KM-JBC (commenced 11/20/2015); and the SEC entered, a consent order finding that(ii) Burn Rose, LLC et al v. BOKF, NA had violated Section 17(a) of the Securities Act of 1933 and Section 10(b) of the Securities Exchange Act and required BOKF, NA to disgorge $1,067,721 of fees and pay d/b/a civil penalty of $600,000. BOKF, NA disgorged the fees and paid the penalty. On August 26, 2016, BOKF, NA was sued in the United States District Court for New Jersey by two bondholders in a putative class action alleging BOKF, NA participated in the fraudulent sale of securities by the principals. While the action remains stayed with no current deadlines pending, plaintiffs recently informed the Court of their intent to request the stay be lifted in a joint status report. BOKF, NA plans to oppose the request to lift the stay. On September 14, 2016, BOKF, NA was sued in the District Court of Tulsa County, Oklahoma by 19 bondholders also alleging BOKF, NA participated in the fraudulent sale of securities by the principals. On April 18, 2023 seven plaintiffs dismissed their claims without prejudice. Discovery on the remaining plaintiff's claims is ongoing. Management is advised by counsel that, in theBOK, Tulsa County District Court Case, No. CJ-2016-03325 (commenced 9/22/2016). In the New Jersey Class Action and the Tulsa County Burn Rose action, a lossthe claimants allege that BOKF, NA was complicit in the fraud committed by Mr. Brogdon. BOKF, NA has multiple defenses to the claims, including the defense that it is not probableexculpated by the terms of the various bond indentures. No action has been taken in the class action by the plaintiffs to establish the class and that the loss,amount of the damages, if any, cannot be reasonably estimated.

On December 28, 2015, in an action brought by the SEC, the New Jersey District Court entered a judgment against the principals involved in issuing the bonds. On January 8, 2020, the Court entered judgment against the principal individual and his wife for $36,805,051 in principal amount and $10,937,831 in pre-judgment interest. The SEC continues to aggressively pursue collection of the judgment. If the individual principal and his wife cannot pay the bonds, a bondholder loss could become probable. Management has been advised by counsel that BOKF, NA has valid defenses to claims of bondholders and that no loss to the Company Approximately $3 million is probable. No provision for losses has been made at this time. BOKF, NA estimates that, upon sale of all remaining collateral securing payment of the bonds, approximately $25 million in principal will remain outstanding. A reasonable estimate cannot be made of the amount of any bondholder loss, though the amount of bondholder loss could be material to the Companyclaimed as damages in the eventBurn Rose action. Management is advised that a loss toon the Company becomesclaims in both the Class Action and the Burn Rose action is not probable.

In the ordinary course of business, BOK Financial and its subsidiaries are subject to legal actions and complaints. Management believes, based upon the opinion of counsel, that the actions and liability or loss, if any, resulting from the final outcomes of the proceedings, will not have a material effect on the Company's financial condition, results of operations or cash flows.

(10) Fees and Commissions Revenue

Fees and commissions revenue is generated through the sales of products, consisting primarily of financial instruments, and the performance of services for customers under contractual obligations. Revenue from providing services for customers is recognized at the time services are provided in an amount that reflects the consideration we expect to be entitled to for those services. Revenue is recognized based on the application of five steps:
Identify the contract with a customer
Identify the performance obligations in the contract
Determine the transaction price
Allocate the transaction price to the performance obligations in the contract
Recognize revenue when (or as) the Company satisfies a performance obligation

For contracts with multiple performance obligations, individual performance obligations are accounted for separately if the customer can benefit from the good or service on its own or with other resources readily available to the customer, and the promise to transfer goods and services to the customer is separately identifiable in the contract. The transaction price is allocated to the performance obligations based on relative standalone selling prices.

Revenue is recognized on a gross basis whenever we have primary responsibility and risk in providing the services or products to our customers and have discretion in establishing the price for the services or products. Revenue is recognized on a net basis whenever we act as an agent for products or services of others.
 
Brokerage and trading revenue includes revenues from trading, customer hedging, retail brokerage and investment banking. Trading revenue includes net realized and unrealized gains primarily related to sales of securities to institutional customers and related derivative contracts. Customer hedging revenue includes realized and unrealized changes in the fair value of derivative contracts held for customer risk management programs including credit valuation adjustments, as necessary. We offer commodity, interest rate, foreign exchange and equity derivatives to our customers. These customer contracts are offset with contracts with selected counterparties and exchanges to minimize changes in market risk from changes in commodity prices, interest rates or foreign exchange rates. Retail brokerage revenue represents fees and commissions earned on sales of fixed income securities, annuities, mutual funds and other financial instruments to retail customers. Investment banking revenue includes fees earned upon completion of underwriting and financial advisory services. Investment banking revenue also includes fees earned in conjunction with loan syndications. Insurance brokerage revenues represents fees and commissions earned on placement of insurance products with carriers for property and casualty and health coverage.
 
Transaction card revenue includes merchant discount fees and electronic funds transfer network fees, net of interchange fees paid to card issuers and assessments paid to card networks. Merchant discount fees represent fees paid by customers for account management and electronic processing of card transactions. Merchant discount fees are recognized at the time the customer's transactions are processed or other services are performed. The Company also maintains the TransFund electronic funds transfer network for the benefit of its members, which includes the Bank.BOKF, NA. Electronic funds transfer fees are recognized as electronic transactions processed on behalf of its members. 
 
Fiduciary and asset management revenue includes fees from asset management, custody, recordkeeping, investment advisory and administration services. Revenue is recognized on an accrual basis at the time the services are performed and may be based on either the fair value of the account or the service provided.
 
Deposit service charges and fees include commercial account service charges, overdraft fees, check card fee revenue and automated service charge and other deposit service fees. Fees are recognized at least quarterly in accordance with published deposit account agreements and disclosure statements for retail accounts or contractual agreements for commercial accounts. Item charges for overdraft or non-sufficient funds items are recognized as items are presented for payment. Account balance charges and activity fees are accrued monthly and collected in arrears. Commercial account activity fees may be offset by an earnings credit based on account balances. Check card fees represent interchange fees paid by a merchant bank for transactions processed from cards issued by the Company. Check card fees are recognized when transactions are processed.

Mortgage banking revenue includes revenues recognized in conjunction with the origination, marketing and servicing of conventional and government-sponsored residential mortgage loans. Mortgage production revenue includes net realized gains (losses) on sales of residential mortgage loans in the secondary market and the net change in unrealized gains (losses) on residential mortgage loans held for sale. Mortgage production revenue also includes changes in the fair value of derivative contracts not designated as hedging instruments related to residential mortgage loan commitments and forward sales contracts. Mortgage servicing revenue includes servicing fee income and late charges on loans serviced for others.

(11) Fair Value Measurements

Fair value is defined by applicable accounting guidance as the price to sell an asset or transfer a liability in an orderly transaction between market participants in the principal market for the given asset or liability at the measurement date based on market conditions at that date. An orderly transaction assumes exposure to the market for a customary period for marketing activities prior to the measurement date and not a forced liquidation or distressed sale. Certain assets and liabilities are recorded in the Company's financial statements at fair value. Some are recorded on a recurring basis and some on a non-recurring basis.

For some assets and liabilities, observable market transactions and market information might be available. For other assets and liabilities, observable market transactions and market information might not be available. A hierarchy for fair value has been established which categorizes into three levels the inputs to valuation techniques used to measure fair value. The three levels are as follows:

Quoted Prices in Active Markets for Identical Assets or Liabilities (Level 1) - Fair value is based on unadjusted quoted prices in active markets for identical assets or liabilities.

- 8579 -


Significant Other Observable Inputs (Level 2) - Fair value is based on significant other observable inputs which are generally determined based on a single price for each financial instrument provided to us by an applicable third-party pricing service and is based on one or more of the following:

Quoted prices for similar, but not identical, assets or liabilities in active markets;
Quoted prices for identical or similar assets or liabilities in inactive markets;
Inputs other than quoted prices that are observable, such as interest rate and yield curves, volatilities, prepayment speeds, loss severities, credit risks and default rates;
Other inputs derived from or corroborated by observable market inputs.

Significant Unobservable Inputs (Level 3) - Fair value is based upon model-based valuation techniques for which at least one significant assumption is not observable in the market.

Transfers between levels are recognized as of the end of the reporting period. There were no transfers in or out of quoted prices in active markets for identical instruments to significant other observable inputs or significant unobservable inputs during the three and six months ended June 30,March 31, 2024 and 2023, and 2022, respectively. Transfers between significant other observable inputs and significant unobservable inputs during the three and six months ended June 30,March 31, 2024 and 2023 and 2022 were immaterial.

The underlying methods used by the third-party pricing services are considered in determining the primary inputs used to determine fair values. Management has evaluated the methodologies employed by the third-party pricing services by comparing the price provided by the pricing service with other sources, including brokers' quotes, sales or purchases of similar instruments and discounted cash flows to establish a basis for reliance on the pricing service values. Significant differences between the pricing service provided value and other sources are discussed with the pricing service to understand the basis for their values. Based on all observable inputs, management may adjust prices obtained from third-party pricing services to more appropriately reflect the prices that would be received to sell assets or paid to transfer liabilities in orderly transactions in the current market. No significant adjustments were made to prices provided by third-party pricing services at June 30, 2023March 31, 2024 or December 31, 2022.2023.

1Residential mortgage loans held for sale measured at fair value on a recurring basis using significant unobservable inputs (Level 3) consist of residential mortgage loans intended for sale to U.S. government agencies that fail to meet conforming standards and are valued at 77.55%77.74% of the unpaid principal balance.
2A reconciliation of the beginning and ending fair value of mortgage servicing rights and disclosures of significant assumptions used to determine fair value are presented in Note 5, Mortgage Banking Activities.
3See Note 3 for detail of fair value of derivative contracts by contract type. Derivative contracts in asset and liability positions that were valued based on quoted prices in active markets for identical instruments (Level 1) are primarily exchange-traded interest rate derivative contracts held for trading purposes.

Following is a description of the Company's valuation methodologies used for assets and liabilities measured on a recurring basis:
Securities

The fair values of trading, available for sale and fair value option securities are based on quoted prices for identical instruments in active markets, when available. If quoted prices for identical instruments are not available, fair values are based on significant other observable inputs such as quoted prices of comparable instruments or interest rates and credit spreads, yield curves, volatilities, prepayment speeds and loss severities. The Company has elected to carry all residential mortgage-backed securities guaranteed by U.S. government agencies held as economic hedges against changes in the fair value of mortgage servicing rights at fair value with changes in the fair value recognized in earnings.

The fair value of certain available for sale municipal and other debt securities may be based on significant unobservable inputs. These significant unobservable inputs include limited observed trades, projected cash flows, current credit rating of the issuers and, when applicable, the insurers of the debt and observed trades of similar debt. Discount rates are primarily based on references to interest rate spreads on comparable securities of similar duration and credit rating as determined by the nationally-recognized rating agencies adjusted for a lack of trading volume. Significant unobservable inputs are developed by investment securities professionals involved in the active trading of similar securities. A summary of significant inputs used to value these securities follows. A management committee composed of senior members from the Company's Capital Markets,Corporate Treasury, Risk Management and Finance departments assesses the appropriateness of these inputs quarterly.

Derivatives

All derivative instruments are carried on the balance sheet at fair value. Fair values for exchange-traded contracts are based on quoted prices. Fair values for over-the-counter interest rate, commodity and foreign exchange contracts are based on valuations provided either by third-party dealers in the contracts, quotes provided by independent pricing services, or a third-party provided pricing model that uses significant other observable market inputs.

Credit risk is considered in determining the fair value of derivative instruments. Management determines fair value adjustments based on various risk factors including, but not limited to, current fair value, probability of default and loss given default.

We also consider our own credit risk in determining the fair value of derivative contracts. Changes in our credit rating would affect the fair value of our derivative liabilities. In the event of a credit downgrade, the fair value of our derivative liabilities would increase.

Residential Mortgage Loans Held for Sale

Residential mortgage loans held for sale are carried on the balance sheet at fair value. The Company has elected to carry all residential mortgage loans originated for sale at fair value. Changes in the fair value of these financial instruments are recognized in earnings. The fair values of residential mortgage loans held for sale are based upon quoted market prices of such loans sold in securitization transactions, including related unfunded loan commitments and forward sales contracts. The fair value of mortgage loans that were unable to be sold to U.S. government agencies were determined using quoted prices of loans that are sold in securitization transactions with a liquidity discount applied.

Fair Value of Assets and Liabilities Measured on a Non-Recurring Basis

Assets measured at fair value on a non-recurring basis include collateral for certain nonaccruing loans and real property and other assets acquired to satisfy loans, which are based primarily on comparisons to completed sales of similar assets.

The following represents the carrying value of assets measured at fair value on a non-recurring basis (and related losses) during the period. The carrying value represents only those assets with a balance at June 30, 2023March 31, 2024 for which the fair value was adjusted during the sixthree months ended June 30, 2023:March 31, 2024 (in thousands):

The fair value of collateral-dependent nonaccruing loans secured by real estate and real estate and other repossessed assets and the related fair value adjustments are generally based on unadjusted third-party appraisals. Our appraisal review policies require appraised values to be supported by observed inputs derived principally from or corroborated by observable market data. Appraisals that are not based on observable inputs or that require significant adjustments or fair value measurements that are not based on third-party appraisals are considered to be based on significant unobservable inputs. Non-recurring fair value measurements of collateral-dependent nonaccruing loans and real estate and other repossessed assets based on significant unobservable inputs are generally due to estimates of current fair values between appraisal dates. Significant unobservable inputs include listing prices for the same or comparable assets, uncorroborated expert opinions or management's knowledge of the collateral or industry. Non-recurring fair value measurements of collateral dependent loans secured by mineral rights are generally determined by our internal staff of engineers on projected cash flows under current market conditions and are based on significant unobservable inputs. Projected cash flows are discounted according to risk characteristics of the underlying oil and gas properties. Assets are evaluated to demonstrate with reasonable certainty that crude oil, natural gas and natural gas liquids can be recovered from known oil and gas reservoirs under existing economic and operating conditions at current prices with existing conventional equipment, operating methods and costs. Significant unobservable inputs are developed by asset management and workout professionals and approved by senior Credit Administration executives.

Item 1. Legal Proceedings
 
See discussion of legal proceedings at Note 6 to the Consolidated Financial Statements.

Item 1A. Risk Factors
There are no material changes from the risk factors set forth under Part I, Item 1A. "Risk Factors" in the Company's Annual Report on Form 10-K for the year ended December 31, 2022, except as described below.

Recent events impacting the financial services industry could adversely affect BOK Financial's business.

Recent events affecting the financial services industry have generated significant market volatility among publicly traded bank holding companies with particular focus on regional banks. These events occurred following a period of rapidly rising interest rates, which resulted in unrealized losses in longer duration securities and loans held by banks as well as more competition for bank deposits. These recent events have, and may continue to, adversely impact the market price and volatility of the Company’s stock. Potentially adverse changes to laws or regulations governing banks and bank holding companies may occur, including but not limited to, increased regulatory scrutiny in the course of routine examinations or otherwise and new regulations directed towards banks of similar size, which could increase the costs of doing business. As a result of recent bank failures the FDIC proposed a special assessment to replenish the Deposit Insurance Fund. If finalized, the special assessment will increase FDIC insurance premiums above the recently increased levels which will result in higher costs.2023.
