Management’s Discussion and Analysis of Financial Condition and Results of Operations
Performance Summary
BOK Financial Corporation (“the Company”) reported net income of $132.8 million or $1.96 per diluted share for the second quarter of 2022 compared to $62.5 million or $0.91 per diluted share for the first quarter of 2022. Increased fee income led by revenue growth from trading activities combined with higher net interest revenue and decreased operating expenses to grow net income in the second quarter. First quarter trading revenue was negatively affected by interest rate volatility and concern over rising inflation.
Pre-provision net revenue ("PPNR"), a non-GAAP measure, was $169.0 million for the second quarter of 2022 compared to $78.7 million for the first quarter of 2022.
Highlights of the second quarter of 2022 included:
•Net interest revenue totaled $274.0 million, an increase of $5.6 million compared to the first quarter of 2022. Average earning assets were $39.1 billion, a decrease of $4.4 billion, largely due to a reduction in our trading inventory. Net interest margin was 2.76 percent for the second quarter of 2022 compared to 2.44 percent for the prior quarter.
•Fees and commissions revenue totaled $173.4 million, an increase of $75.7 million. Brokerage and trading revenue increased $71.1 million following trading losses in the prior quarter. Revenue growth in all other fee-generating business activities was partially offset by a $5.3 million decrease in mortgage banking revenue.
•The net benefit of the changes in fair value of mortgage servicing rights and related economic hedges was $1.9 million for the second quarter of 2022 compared to a net cost of $8.4 million for the first quarter of 2022 due to reduced price sensitivity in the second quarter.
•Other operating expense totaled $273.7 million, a decrease of $4.0 million. Personnel expense decreased $4.3 million, largely due to lower share-based compensation expense. Non-personnel expense was relatively consistent with the prior quarter.
•Period-end outstanding loan balances totaled $21.3 billion at June 30, 2022, growing $617 million compared to March 31, 2022, largely due to growth in commercial loans. Excluding a decrease in loans originated through the Small Business Administration's Paycheck Protection Program ("PPP"), outstanding loan balances increased $711 million. Unfunded loan commitments also grew by $979 million during the second quarter. Average loan balances increased $594 million compared to the prior quarter to $21.1 billion.
•No provision for expected credit losses was necessary for the second quarter of 2022, consistent with the prior quarter. An increase in required provision due to loan growth and changes in our economic outlook was offset by a sustained trend of improving credit quality metrics. The combined allowance for credit losses totaled $283 million or 1.33 percent of outstanding loans, excluding PPP loans, at June 30, 2022. The combined allowance for credit losses was $283 million or 1.38 percent of outstanding loans, excluding PPP loans, at March 31, 2022.
•Nonperforming assets not guaranteed by U.S. government agencies decreased $13 million compared to March 31, 2022. Potential problem loans decreased $39 million while other loans especially mentioned decreased $18 million. Net recoveries were $799 thousand or 0.02 percent of average loans on an annualized basis for the second quarter of 2022, excluding PPP loans. Net charge-offs were 0.06 percent of average loans, excluding PPP loans, over the last four quarters. Net charge-offs were $6.0 million or 0.12 percent of average loans on an annualized basis for the first quarter of 2022, excluding PPP loans.
•Period-end deposits were $38.6 billion at June 30, 2022, an $807 million decrease compared to March 31, 2022 as customers begin to redeploy cash resources to higher yielding alternatives and resume spending following the height of the pandemic. Average deposits decreased $1.8 billion, including a $1.9 billion decrease in interest bearing deposits.
•The common equity Tier 1 capital ratio at June 30, 2022 was 11.61 percent. Other regulatory capital ratios included the Tier 1 capital ratio at 11.63 percent, total capital ratio at 12.59 percent, and leverage ratio at 9.12 percent. At March 31, 2022, the common equity Tier 1 capital ratio was 11.30 percent, the Tier 1 capital ratio was 11.31 percent, total capital ratio was 12.25 percent, and leverage ratio was 8.47 percent.

•The Company repurchased 294,084 shares of common stock at an average price of $82.98 per share in the second quarter of 2022 and 475,877 shares at an average price of $101.02 in the first quarter of 2022. We view share buybacks opportunistically, but within the context of maintaining our strong capital position.
•The Company paid a regular cash dividend of $35.9 million or $0.53 per common share during the second quarter of 2022. On August 2, 2022, the board of directors approved a quarterly cash dividend of $0.53 per common share payable on or about August 25, 2022 to shareholders of record as of August 16, 2022.
Highlights of the six months ended June 30, 2022 included:
•Tax-equivalent net interest revenue totaled $546.4 million for the six months ended June 30, 2022 and $565.4 million for the six months ended June 30, 2021. Net interest revenue decreased $16.3 million from changes in earning assets and $2.6 million from changes in interest rates. Net interest margin was 2.60 percent compared to 2.61 percent. Average earning assets decreased $2.8 billion to $41.3 billion, primarily due to lower loan balances and a reduction in trading securities. In response to rising inflation, the Federal Reserve increased the federal funds rate 150 basis points since the beginning of 2022, which led to an 18 basis point increase in loan yields while funding costs only increased 4 basis points. PPP loan fees totaled $6.5 million for the six months ended June 30, 2022 and $22.3 million for the six months ended June 30, 2021. PPP loan fees remaining to be recognized totaled $1.1 million as of June 30, 2022. The yield on trading securities decreased 19 basis points due to a lower weighted average coupon rate.
•Fees and commissions revenue totaled $271.0 million for the six months ended June 30, 2022, a $60.6 million decrease compared to the six months ended June 30, 2021, largely due to a reduction in brokerage and trading revenue and mortgage banking revenue. A $58.8 million decrease in trading revenue due to disruption in the fixed income markets related to economic uncertainty was partially offset by a $19.7 million increase in customer hedging revenue. Mortgage banking revenue decreased $30.3 million as rapidly rising mortgage interest rates and continued inventory shortages have adversely affected both loan production volume and margins. Other revenue decreased $16.3 million as a result of lower operating revenue from repossessed oil and gas assets due to the sale of properties in the third quarter of 2021.
•Other gains and losses, net decreased $35.9 million. The prior year included gains on alternative investments and sales of repossessed assets while the current year included the write-down of a repossessed equity interest in a midstream entity.
•Total operating expense was $551.3 million for the six months ended June 30, 2022, a decrease of $35.7 million compared to the six months ended June 30, 2021. Personnel expense decreased $30.9 million, primarily due to lower incentive compensation costs related to reduced cash-based incentives resulting from lower loan and trading volume and deferred compensation expense, which is largely offset by a decrease in the value of related rabbi trust investments. Non-personnel expense decreased $4.8 million to $237.1 million. Lower mortgage banking costs and repossessed asset operating expenses were largely offset by increased business promotion, occupancy and equipment, and data processing costs.
•No provision for credit losses was necessary for the six months ended June 30, 2022. An increase in allowance related to our lending activities from strong loan growth and changes in our reasonable and supportable forecast were offset by the impact from improving credit metrics. A $60.0 million negative provision for credit losses was recorded for the six months ended June 30, 2021 due to forecasts for improving macroeconomic factors, including stabilizing energy prices, and improving credit quality metrics.

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 $276.1 million for the second quarter of 2022 and $270.4 million for the first quarter of 2022. Compared to the first quarter of 2022, net interest revenue increased $18.3 million from changes in interest rates and decreased $12.6 million 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 decreased $4.4 billion compared to the first quarter of 2022. Average trading securities were reduced by $4.4 billion as we reduced our inventory of low-coupon residential mortgage-backed securities and repositioned the trading portfolio in response to rising mortgage interest rates. Average loan balances increased $594 million, largely due to growth in commercial loans, partially offset by a reduction of PPP 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, decreased $834 million while investment securities increased $416 million. Late in the second quarter of 2022, we transferred $2.4 billion of U.S. government agency mortgage-backed securities from available for sale to investment securities to limit the effect of future rate increases on the tangible common equity ratio. We purchase securities to supplement earnings and to manage interest rate risk. Interest-bearing cash and cash equivalents decreased $207 million.
Total average deposits were reduced by $1.8 billion compared to the first quarter of 2022 as customers begin to deploy cash resources into higher yielding alternatives and resume normal spending levels following the height of the pandemic. Funds purchased and repurchase agreements decreased $780 million while other borrowings increased $153 million.
Net interest margin was 2.76 percent compared to 2.44 percent in the first quarter of 2022. The tax-equivalent yield on earning assets was 2.96 percent, an increase of 38 basis points. Loan yields increased 35 basis points to 3.92 percent. The yield on trading securities was up 29 basis points to 2.00 percent. The available for sale securities portfolio yield increased 7 basis points to 1.84 percent. The yield on fair value option securities increased 11 basis points to 2.92 percent. The yield on investment securities decreased 272 basis points due to the transfer of securities from the available for sale portfolio to the investment portfolio. The yield on interest-bearing cash and cash equivalents increased 65 basis points.
Funding costs were 0.31 percent, a 10 basis point increase. The cost of interest bearing deposits increased 12 basis points to 0.24 percent. The cost of funds purchased and repurchase agreements decreased 42 basis points to 0.53 percent while the cost of other borrowings increased 63 basis points to 1.01 percent. The benefit to net interest margin from assets funded by non-interest liabilities was 11 basis points, an increase of 4 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 78 percent 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 would be asset sensitive, which means that assets generally reprice more quickly than liabilities. One of the strategies that we use to manage toward a relative rate-neutral position is to purchase fixed rate residential mortgage-backed securities issued primarily by U.S. government agencies and fund them with market-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 39 percent of total revenue for the second quarter of 2022, excluding provision for credit losses and gains and losses on other assets, securities and derivatives and the change in the fair value of mortgage servicing rights. We believe that a variety of fee revenue sources provides an offset to changes in 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 rising interest rates that we expect will result in growth in net interest revenue or fiduciary and asset management revenue may also decrease 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. As interest rates are expected to move higher, we expect to experience increased benefits to our net interest margin, which provides an offset to reduced mortgage-related fee income. 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, including the recent impact of the COVID-19 pandemic, 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 and investment banking, increased $71.1 million or 263 percent compared to the first quarter of 2022.
- 5 -

Trading revenue includes net realized and unrealized gains and losses primarily related to residential mortgage-backed securities guaranteed by U.S. government agencies and related derivative instruments that enable our mortgage banking customers to manage their production risk. 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 increased $66.0 million compared to the prior quarter..Disruption in the fixed income markets related to uncertainty around rising inflation and interest rates adversely affected the value of trading securities during the first quarter of 2022. During the second quarter, we fully sold our inventory of low-coupon, U.S. government agency residential mortgage-backed 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 Derivative 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 $13.1 million for the second quarter of 2022, up $2.2 million over the prior quarter. 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 $11.8 million for the second quarter of 2022, an increase of $4.2 million compared to the first quarter of 2022, related to the timing and volume of completed loan syndication transactions.
Transaction Card Revenue
Transaction card revenue totaled $26.9 million for the second quarter of 2022, an increase of $2.7 million compared to the first quarter of 2022. Transaction volume is rising as customers return to more normal spending levels following the height of the pandemic. , largely due to stimulus measures and the broader reopening of the U.S. economy.
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. Approximately 90 percent of fiduciary and asset management revenue is primarily 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 increased $3.4 million over the first quarter of 2022. Money market fund revenue share grew $3.0 million. The second quarter also included an increase in seasonal tax preparation fees of $1.8 million and reduction of fee waivers of $2.1 million. We voluntarily waived certain administration fees on the Cavanal Hill money market funds in order to maintain positive yields on these funds during the short-term interest rate environment. As of June 30, 2022, we are no longer waiving those fees. These increases were partially offset by a $3.2 million reduction in trust business line fees related to decreased asset under management billable fees, consistent with market driven declines in equities, which account for a third of the assets under management or administration.

Assets under management as of June 30, 2022 consist of 44 percent fixed income, 34 percent equities, 14 percent cash, and 8 percent alternative investments.
Deposit Service Charges and Fees
Deposit service charges and fees increased $1.5 million driven largely by commercial customer activity. Overdraft and non-sufficient funds fees earned primarily on consumer deposit accounts totaled $6.6 million for the second quarter of 2022, largely unchanged from the prior quarter.
Mortgage Banking Revenue
Mortgage banking revenue decreased $5.3 million or 32 percent compared to the first quarter of 2022 due to lower production volume combined with narrowing margins. Rapidly rising interest rates and continued inventory shortages have resulted in fewer refinance opportunities and heightened competitive pricing pressure. Mortgage production volume decreased $102 million to $306 million. Production revenue as a percentage of production volume, which includes unrealized gains and losses on our mortgage commitment pipeline and related hedges, decreased 140 basis points to (0.16) percent, affected by increased market competition and our securitization of loans previously repurchased from GNMA pools.

Net gains on other assets, securities and derivatives
Other gains and losses, net decreased $6.0 million compared to the first quarter of 2022 primarily related to a write-down of a repossessed equity interest in a midstream entity.
As discussed in the Market Risk section following, the fair value of our mortgage servicing rights ("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. Three bulk mortgage servicing rights portfolios were acquired during the second quarter of 2022. These acquisitions added $3.5 billion in unpaid principal balance comprised of conventional, low note rate, strong performing loans.

Personnel expense
Personnel expense decreased $4.3 million compared to the first quarter of 2022. Share-based compensation expense decreased $3.9 million resulting from changes in vesting assumptions. Regular compensation expense increased as we recognized a full quarter of expense related to annual merit increases and employee benefits expense decreased due to seasonal changes in payroll taxes. An increase in cash-based incentive compensation expense was largely driven by growing commercial activity. A decrease in deferred compensation expense reflected changes in the value of rabbi trust assets.
Non-personnel operating expense
Non-personnel expense totaled $118.7 million for the second quarter of 2022, consistent with the first quarter of 2022. Mortgage banking costs increased $1.6 million, primarily due to additional accruals related to default servicing and loss mitigation costs on loans serviced for others. Increases in data processing and communications expense of $1.4 million and professional fees and services expense of $1.1 million were due to ongoing technology projects. These increases were offset by a decrease in net occupancy and equipment expense of $3.4 million.
Income Taxes
The effective tax rate was 21.4 percent for the second quarter of 2022 and 20.6 percent for the first quarter of 2022. The effective rate for the second quarter of 2022 increased primarily due to the increase in net income before tax. The effective tax rates for the six months ended June 30, 2022 and June 30, 2021 were 21.1 percent and 22.6 percent, respectively. The effective rate decreased primarily due to the increase in excess tax benefits from vested share-based compensation and a decrease in the Oklahoma tax rate.
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.
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 operating lines of business is transfer priced at rates that approximate market rates for funds with similar repricing and cash flow characteristics. Market rates are generally based on the applicable wholesale borrowing rates or 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.
- 11 -

The value of funds provided by the operating lines of business to the Funds Management unit is also based on rates that approximate wholesale market rates for funds with similar repricing and cash flow characteristics. Market rates are generally based on a proxy of wholesale borrowing rates or interest rate swap rates. The funds credit formula applied to deposit products with indeterminate maturities is established based on their repricing characteristics reflected in a combination 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.
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 $62.8 million compared to the first quarter of 2022. Net interest revenue increased $18.1 million, primarily due to loan growth and increased spreads on deposits sold to our Funds Management unit. Net charge-offs decreased $6.8 million. Other operating revenue increased $62.1 million largely due to trading activity returning to more normal levels following trading losses incurred in the prior quarter from market disruptions. Operating expense increased $10.5 million due to a combination of increased incentive compensation expense largely related to growing commercial activity and additional accruals for mortgage loan default servicing and loss mitigation costs.

Operating revenue decreased $3.9 million or 11 percent compared to the prior quarter. Mortgage production volume decreased $102 million to $306 million and production revenue as a percentage of production volumes decreased 140 basis points resulting in a $5.3 million decrease in mortgage banking revenues. Operating expense increased $3.9 million or 8 percent. Business promotion expense increased $1.8 million and mortgage banking costs increased $1.6 million related to accruals for default servicing and loss mitigation costs. Corporate expense allocations decreased $2.0 million or 16 percent compared to the first quarter of 2022.

Wealth Management
Wealth Management contributed $27.3 million to consolidated net income in the second quarter of 2022 compared to a net loss of $4.5 million in the first quarter of 2022. Trading activity has returned to more normal levels following disruption in the fixed income markets related to uncertainty around rising inflation and interest rates that occurred in the first quarter of 2022.

Certain percentage increases (decreases) in non-fees and commissions revenue are not meaningful for comparison purposes based on the nature of the item.
Combined net interest revenue and fee revenue increased $43.7 million or 54 percent. Total revenue from trading activities increased $47.4 million compared to the first quarter of 2022. Market disruptions during the first quarter of 2022 reduced demand for low-coupon, fixed-rate U.S. government agency residential mortgage-backed securities. These securities were fully sold during the second quarter. Growth in money market fund revenue, seasonal tax preparation fees and a reduction in fee waivers combined to increase fiduciary and asset management revenue $6.6 million. This increase was partially offset by a $3.2 million reduction in trust business line fees related to decreased asset under management billable fees, consistent with market driven declines in equities, which account for a third of the assets under management or administration. Operating expense increased $1.8 million or 2 percent, primarily due to increased volume-driven incentive compensation costs and a full quarter's impact of annual merit increases.

Average outstanding loans attributed to the Wealth Management segment increased $39 million or 2 percent. Average Wealth Management deposits decreased $1.1 billion or 12 percent to $8.5 billion as customers redeployed deposits into higher yielding alternatives.
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, 2022 and December 31, 2021.
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 decreased $2.0 billion to $2.9 billion during the second quarter of 2022 as we reduced our inventory of low-coupon mortgage-backed securities and repositioned the trading portfolio in response to rising mortgage interest rates. 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, 2022, the carrying value of investment (held-to-maturity) securities was $2.6 billion, including a $717 thousand allowance for expected credit losses compared to $184 million at March 31, 2022 with a $633 thousand allowance for expected credit losses. The fair value of investment securities was $2.6 billion at June 30, 2022 and $191 million at March 31, 2022. Investment securities consist primarily of residential mortgage-backed securities issued by U.S. government agencies, intermediate and long-term, fixed rate Oklahoma and Texas municipal bonds, and taxable Texas school construction bonds. During the second quarter of 2022, the Company transferred certain U.S. government agency mortgage-backed securities from the available for sale portfolio to the investment securities portfolio to limit the effect of future rate increases on the tangible common equity ratio. No gains or losses were recognized in the Consolidated Statements of Earnings at the time of the transfer. At the time of transfer, the fair value totaled $2.4 billion, amortized cost totaled $2.7 billion and the pretax unrealized loss totaled $268 million. Transfers of debt securities into the investment securities portfolio are made at fair value at the date of transfer. The unrealized holding gain or loss at the date of transfer is retained in Accumulated Other Comprehensive Income and in the carrying value of the investment securities portfolio. Such amounts are amortized over the estimated remaining life of the security as an adjustment to yield, offsetting the related amortization of the premium or accretion of the discount on the transferred securities.
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 $10.7 billion at June 30, 2022, a $2.8 billion decrease compared to March 31, 2022, primarily due to the transfer of securities from the available for sale portfolio to the investment securities portfolio discussed above. At June 30, 2022, 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 prepayment 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, 2022 is 3.4 years. Management estimates the duration extends to 3.8 years assuming an immediate 200 basis point upward shock. The estimated duration contracts to 3.0 years assuming a 100 basis point decline in the current low rate environment. 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. Throughout the second quarter of 2022, this exposure was reported and monitored by management, and the portfolio's actual performance remained within expectations.

Bank-Owned Life Insurance
We have approximately $410 million of bank-owned life insurance at June 30, 2022. 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. Our separate account holdings are invested in diversified portfolios of investment-grade fixed income securities and cash equivalents, including U.S. Treasury and Agency 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, 2022, the fair value of investments held in separate accounts covered by the stable value wrap was approximately $291 million. As the underlying fair value of the investments held in separate accounts at June 30, 2022 was below the net book value of the investments, $23 million of cash surrender value was supported by the stable value wrap. Future rate increases may cause impairment as the fair value deterioration could exceed the stable value wrap protection. The stable value wrap is provided by a domestic financial institution. The remaining cash surrender value of $94 million primarily represents the cash surrender value of policies held in general accounts and other amounts due from various insurance companies.

Loans
The aggregate loan portfolio before allowance for loan losses totaled $21.3 billion at June 30, 2022, a $617 million increase over March 31, 2022. Core loans, which exclude paycheck protection program loans, grew by $711 million, primarily due to growth in commercial loans. Unfunded loan commitments also grew by $979 million during the second quarter.

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 $13.6 billion or 64 percent of the loan portfolio at June 30, 2022, a $696 million increase over March 31, 2022, growing in all commercial loan categories.

Approximately 75 percent 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 percent 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 $3.4 billion or 16 percent of total loans at June 30, 2022, a $195 million increase over March 31, 2022. Approximately $2.6 billion of energy loans were to oil and gas producers, a $188 million increase over March 31, 2022. 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 72 percent of the committed production loans are secured by properties primarily producing oil and 28 percent of the committed production loans are secured by properties primarily producing natural gas.
Loans to midstream oil and gas companies totaled $640 million at June 30, 2022, a $10 million increase compared to March 31, 2022. Loans to borrowers that provide services to the energy industry totaled $134 million at June 30, 2022, an increase of $14 million. Loans to other energy borrowers, including those engaged in wholesale or retail energy sales, totaled $8.2 million, a decrease of $15 million compared to the prior quarter.
Unfunded energy loan commitments were $3.4 billion at June 30, 2022, growing $342 million over March 31, 2022.
The healthcare sector of the loan portfolio totaled $3.7 billion or 17 percent of total loans. Healthcare loans increased $255 million over March 31, 2022, primarily due to growth in loans to senior housing facilities. This was partially offset by a decline in balances to other medical practices compared to the prior quarter. 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 $3.4 billion or 16 percent of total loans, a $70 million increase 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, Native American tribal casino operations, foundations and not-for-profit organizations, educational services and specialty trade contractors. Approximately $1.6 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 $3.1 billion or 14 percent of total loans, an increase of $175 million over the prior quarter. General business loans consist of $1.6 billion of wholesale/retail loans and $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, 2022, the outstanding principal balance of these loans totaled $4.6 billion, including $2.0 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 percent 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.
The outstanding balance of commercial real estate loans increased $5.2 million over March 31, 2022 to $4.1 billion or 19 percent of total loans at June 30, 2022. Loans secured by industrial facilities grew by $42 million to $954 million. Multifamily residential loans increased $11 million to $879 million at June 30, 2022. Loans secured by retail facilities decreased $30 million to $637 million and loans secured by other commercial real estate properties decreased $11 million to $425 million.
Approximately 69 percent of loans in this segment are in our geographic footprint based on collateral location. The largest concentration of loans in this segment outside our footprint is Utah, totaling 10 percent of the segment. All other states represent less than 5 percent individually.
Paycheck Protection Program
We actively participated in programs initiated by the Coronavirus Aid, Relief and Economic Security Act ("CARES Act"), including the Small Business Administration's ("SBA") Paycheck Protection Program ("PPP") that began on April 3, 2020. PPP provided fully forgivable loans when utilized for qualified expenditures, including to help small businesses maintain payrolls during the COVID-19 pandemic. The remaining loans in this portfolio generally have a contractual term of five years, though most are expected to be forgiven prior to maturity after completion of a compliance period. Loans are guaranteed and amounts forgiven will be reimbursed to the Company by the SBA. The loans carry a fixed interest rate of 1 percent. Interest plus loan fees, which vary depending on loan size, are accrued over the contractual life of the loan. Remaining unaccreted origination fees were not significant at June 30, 2022.
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. 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 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, which includes home equity loans, and personal 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.
Personal loans consist primarily of loans to Wealth Management clients secured by the cash surrender value of insurance policies and marketable securities. It also includes direct loans secured by and for the purchase of automobiles, recreational and marine equipment as well as unsecured loans.
Approximately 91 percent 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 operating location.
- 22 -

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. After peaking in the second quarter of 2021, these loans are migrating toward pre-COVID levels through payoffs or sales.
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").
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 rate loan originations are sold in the secondary market and we only retain repurchase obligations under standard underwriting representations and warranties.

Customer Derivative 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 derivative 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 deteriorated such that either the fair value of underlying collateral no longer supported the contract or the customer or the counterparty’s ability to provide margin collateral was 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, 2022, the net fair values of derivative contracts, before consideration of cash margin, reported as assets under these programs totaled $2.0 billion compared to $2.4 billion at March 31, 2022. At June 30, 2022, the net fair value of our derivative contracts included $1.9 billion for energy contracts, $96 million for interest rate swaps and $70 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 $2.0 billion at June 30, 2022 and $2.4 billion at March 31, 2022.
At June 30, 2022, total derivative assets were reduced by $75 million of cash collateral received from counterparties and total derivative liabilities were reduced by $1.9 billion 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 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, 2022 follows in Table 15.
Table 15 -- Fair Value of Derivative Contracts
(In thousands)

Customers |  | $ | 1,837,191 |
Banks and other financial institutions |  | 69,709 |
Exchanges and clearing organizations |  | 43,978 |
Fair value of customer risk management program asset derivative contracts, net |  | $ | 1,950,878 |

At June 30, 2022, our largest derivative exposure was to an energy customer for $94 million.
Our customer derivative 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. Also, changes in commodity prices affect the amount of regulatory capital we are required to hold as support for the fair value of our derivative assets. These risks are modeled as part of the management of these programs. Based on current prices, a decrease in market prices equivalent to $91.47 per barrel of oil would decrease the fair value of derivative assets by $510 million, with lending customers comprising the bulk of the assets. An increase in prices equivalent to $120.05 per barrel of oil would increase the fair value of derivative assets by $673 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, 2022, 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, 2022, 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") growth, civilian unemployment rate and West Texas Intermediate ("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.
No provision for credit losses was necessary for the second quarter of 2022. An increase in allowance related to our lending activities from the strong loan growth during the quarter and changes in our reasonable and supportable forecast, primarily related to the economic outlook from the Federal Reserve's actions to control inflation, were offset by the impact of a sustained trend of improving credit quality metrics.
- 28 -

The probability weightings of our base case reasonable and supportable forecast decreased and our downside reasonable and supportable forecast increased in the second quarter of 2022 compared to the first quarter of 2022 as the level of uncertainty in the current economic outlook increased. In addition, the key economic factors were generally less favorable to economic growth across all scenarios. These changes resulted in a $15.8 million increase in the provision for credit losses. This increase was largely offset by a decrease in expected losses on commercial services and wholesale / retail loans.
A summary of macroeconomic variables considered in developing our estimate of expected credit losses at June 30, 2022 follows:

| Base | Downside | Upside
Scenario probability weighting | 55% | 35% | 10%
Economic outlook | The Russia-Ukraine conflict remains isolated and conditions improve by the fourth quarter of 2022. The federal funds rate is increased at Federal Reserve Open Market ("FOMC") meetings through June 2023, which results in a target range of 3.50 percent to 3.75 percent. Labor force participants continue to re-enter the job market to meet the record number of job openings. Inflation pressures cause modest declines in real household income compared to pre-pandemic levels, but is offset by a drawdown in savings. This results in below-trend GDP growth. | The Russia-Ukraine conflict persists through second quarter of 2023, but remains isolated. Additional surges in commodity prices exacerbated by supply chain dislocations create higher levels of inflation forcing the Federal Reserve to adopt a more aggressive monetary policy to combat the inflationary environment. This results in a target range of 4.50 percent to 4.75 percent by June 2023. This pushes the United States into a recession, with a contraction in economic activity and a sharp increase in the unemployment rate. | The Russia-Ukraine conflict remains isolated and conditions improve in the third quarter 2022. The federal funds rate is increased at FOMC meetings through June 2023, which results in a target range of 3.00 percent to 3.25 percent. Labor force participants continue to re-enter the job market to meet the record number 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 1.4 percent over the next 12 months. –Civilian unemployment rate of 3.7 percent in the third quarter of 2022 increases to 4.0 percent by the second quarter of 2023. –WTI oil prices are projected to generally follow the NYMEX forward curve that existed at the end of June 2022 and are expected to average $98.15 per barrel over the next 12 months. | –GDP is forecasted to contract 1.8 percent over the next twelve months. –Civilian unemployment rate of 4.2 percent in the third quarter of 2022 increases to 6.9 percent in the second quarter of 2023. –WTI oil prices are projected to average $105.36 over the next 12 months, with a peak of $130.37 in the fourth quarter of 2022 and falling 39% over the following two quarters. | –GDP is forecasted to grow by 2.4 percent over the next 12 months. –Civilian unemployment rate of 3.5 percent in the third quarter of 2022 increases to 3.6 percent by the second quarter of 2023. –WTI oil prices are projected to average $90.27 per barrel over the next 12 months.

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 Case scenario, a 100% Downside case would result in an
additional $118 million in quantitative reserve at June 30, 2022. Such sensitivity calculations do not necessarily reflect the nature and extent of future changes in the related allowance.

Growth in loan balances resulted in a $5.3 million increase in allowance, offset by a $1.9 million decrease related to improved risk grading, a $3.0 million decrease related to changes in payment characteristics of the portfolio and net recoveries of $799 thousand during the second quarter of 2022. Improved risk grading during the quarter was primarily related to energy, services, general business and commercial real estate loans, partially offset by slightly worse risk grades in the healthcare portfolio. A summary of outstanding loan balances by risk grade is included in Note 4 to the Consolidated Financial Statements. Non-pass grade loans include other loans especially mentioned, defined by regulatory guidelines as loans that are currently performing in compliance with original terms but may have a potential weakness that deserves management’s close attention, accruing substandard loans, and nonaccruing loans. Non-pass grade loans totaled $323 million at June 30, 2022, a $66 million decrease compared to March 31, 2022. Non-pass graded loans were primarily composed of $81 million or 2 percent of services loans, $58 million or 2 percent of energy loans, $58 million or 2 percent of healthcare loans, $50 million or 1 percent of loans to individuals, $43 million or 1 percent of general business loans and $32 million or 1 percent of commercial real estate loans.
At June 30, 2022, the allowance for loan losses totaled $241 million or 1.13 percent of outstanding loans. Excluding residential mortgage loans guaranteed by U.S. government agencies, the allowance for loan losses was 251 percent of nonaccruing loans. The combined allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan commitments was $283 million or 1.33 percent of outstanding loans and 295 percent of nonaccruing loans at June 30, 2022.
No provision for credit losses was necessary for the first quarter of 2022. At March 31, 2022, the allowance for loan losses was $246 million or 1.19 percent of outstanding loans. Excluding residential mortgage loans guaranteed by U.S. government agencies, the allowance for loan losses was 230 percent of nonaccruing loans. The combined allowance for loan losses and accrual for off-balance sheet credit risk from unfunded loan commitments was $283 million or 1.37 percent of outstanding loans and 264 percent of nonaccruing loans.
Net Loans Charged Off
Net recoveries of commercial loans were $1.6 million in the second quarter of 2022. Net commercial real estate loan charge-offs were $62 thousand and net charge-offs of loans to individuals were $721 thousand. 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") 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 is based on probability of default and loss given default assumptions that align with similarly graded loans. Qualitative adjustment may be used, if necessary.
- 30 -

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. 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.

2 Excludes residential mortgage and PPP loans guaranteed by U.S. government agencies.
- 31 -

Excluding assets guaranteed by U.S. government agencies, nonperforming assets decreased $13 million from March 31, 2022, primarily due to a $5.1 million decrease in nonaccruing commercial real estate loans and a $4.1 million decrease in nonaccruing energy loans. Newly identified nonaccruing loans totaled $4.4 million, offset by $8.4 million of payments, $4.0 million in foreclosures and $1.4 million of charge-offs. The Company generally retains nonperforming assets to maximize potential recovery, which may cause future nonperforming assets to decrease more slowly.

We foreclose on loans guaranteed by U.S. government agencies in accordance with agency guidelines. Generally these loans are not eligible for modification programs or have failed to comply with modified loan terms. Principal is guaranteed by agencies of the U.S. government, subject to limitations and credit risk is limited. At foreclosure, these amounts are transferred to claims receivable accounts. These properties will be conveyed to the agencies once applicable criteria have been met.

Liquidity and Capital
Based on the average balances for the second quarter of 2022, approximately 82 percent of our funding was provided by deposit accounts, 5 percent from borrowed funds, less than 1 percent from long-term subordinated debt and 10 percent from equity. Our funding sources, which primarily include deposits and borrowings from the Federal Home Loan Banks and other banks, provide adequate liquidity to meet our operating needs.
Subsidiary Bank
Deposits and borrowed funds are the primary sources of liquidity for BOKF, NA, the wholly owned subsidiary bank of BOK Financial. We compete for retail and commercial deposits by offering a broad range of products and services and focusing on customer convenience. Retail deposit growth is supported through personal and small business checking, online bill paying services, mobile banking services, an extensive network of branch locations and ATMs and our ExpressBank call center. Commercial deposit growth is supported by offering treasury management and lockbox services. We also acquire brokered deposits when the cost of funds is advantageous to other funding sources.
Average deposits for the second quarter of 2022 totaled $38.6 billion, a $1.8 billion decrease compared to the first quarter of 2022. Deposit balances are beginning to reduce as customers start to deploy cash resources into higher yielding alternatives and increase spending levels following the height of the pandemic. Interest-bearing transaction account balances decreased $1.7 billion. Demand deposits grew by $140 million and savings account balances were up $34 million. Certificate of deposit balances decreased $216 million.

Average Commercial Banking deposit balances decreased $661 million compared to the first quarter of 2022. Interest-bearing transaction account balances decreased $731 million and time deposits decreased $223 million. Demand deposit balances were up $292 million. Commercial deposit balances have decreased as short-term rates move higher, enhancing their investment alternatives.
Average Consumer Banking deposit balances increased $130 million over the prior quarter, largely due to annual income tax deadlines. Demand deposit balances increased $68 million, interest-bearing transaction deposit balances increased $55 million and savings account balances increased $35 million.
Average Wealth Management deposits decreased $1.1 billion compared to the first quarter of 2022. A $925 million decrease in interest-bearing transaction accounts and a $233 million decrease in demand deposit balances was partially offset by a $22 million increase in time deposit balances.

In addition to deposits, liquidity is provided primarily by federal funds purchased, securities repurchase agreements and Federal Home Loan Bank 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 Company has no wholesale federal funds purchased at June 30, 2022. Securities repurchase agreements generally mature within 90 days and are secured by certain available for sale and trading securities. Federal Home Loan Bank 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 $1.3 billion during the quarter, compared to $1.1 billion in the first quarter of 2022.
At June 30, 2022, the estimated unused credit available to BOKF, NA from collateralized sources was approximately $15 billion.
A summary of other borrowings for BOK Financial on a consolidated basis follows in Table 21.

1 Parent Company only.
BOKF, NA also has a liability related to the repurchase of certain delinquent residential mortgage loans previously sold in 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, 2022, cash and interest-bearing cash and cash equivalents held by the parent company totaled $162 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, 2022, based upon the most restrictive limitations as well as management's internal capital policy, BOKF, NA could declare up to $206 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, 2022 was $4.7 billion, a $112 million decrease compared to March 31, 2022. Net income less cash dividends paid increased equity $97 million during the second quarter of 2022. Changes in interest rates resulted in a $185 million decrease in accumulated other comprehensive income compared to March 31, 2022. We also repurchased $24 million of common stock during the second quarter of 2022. 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 April 30, 2019, 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, 2022, 4,103,431 shares have been repurchased under this authorization. The Company repurchased 294,084 shares of common stock at an average price of $82.98 a share in the second quarter of 2022. 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 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 CECL 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 10 basis points to the Company's Common equity Tier 1 capital at June 30, 2022.
The capital ratios for BOK Financial on a consolidated basis are presented in Table 22.

Capital resources of financial institutions are also regularly measured by the tangible common shareholders’ equity ratio. Tangible common shareholders’ equity is shareholders’ equity as defined by generally accepted accounting principles in the United States of America (“GAAP”) less intangible assets and equity which does not benefit common shareholders. Equity that does not benefit common shareholders includes preferred equity. This non-GAAP measure is a valuable indicator of a financial institution’s capital strength since it eliminates intangible assets from shareholders’ equity and retains the effect of unrealized losses on securities and other components of accumulated other comprehensive income in shareholders’ equity.
Table 23 provides a reconciliation of the non-GAAP measures with financial measures defined by GAAP.

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 to enable 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.
Off-Balance Sheet Arrangements
See Note 4 to the Consolidated Financial Statements for a discussion of the Company’s significant off-balance sheet commitments.
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.
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-pledged assets, among other things. Further, the Board 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 5 percent. The results of a 200 basis point decrease in interest rates in the current low-rate environment are not meaningful. Until such time as it becomes meaningful, we will instead report the effect of a 100 basis point decrease in interest rates. Management also reviews alternative rate changes and time periods.
The Company’s primary interest rate exposures include the Federal Funds rate, which affects short-term borrowings, and the prime lending rate, LIBOR and SOFR, which are 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 percent more sensitive to changes in rates, the variation in net interest revenue over the next twelve months would be 3.99 percent, or $51.3 million for the 200 basis point increase scenario. Alternatively, should deposit funding costs be 10 percent less sensitive to changes in rates, the variation in net interest revenue over the next twelve months would be 6.39 percent, or $82.2 million for the 200 basis point increase 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 points, net interest revenue would increase by approximately 2.66 percent, or $34.2 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.
- 41 -

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 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"), 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 Risk 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.
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”), and sensitivity analysis.
Stressed VaR is calculated using the same internal models as used for the VaR-based measure. Stressed VaR 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 VaR 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 VaR based measures for the three months ended June 30, 2022, March 31, 2022, June 30, 2021 and Mar. 31, 2021. In the second quarter of 2022, both VaR measures decreased from the previous quarter. This decrease resulted from a decline in total trading assets and a decrease in basis risk between trading assets and their economic hedges.

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 modeled 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 million market risk limit for the trading portfolio, net of economic hedges.

Governance
Model Risk Governance and Review
BOK Financial has an internal but independent Model Risk Governance and Review ("MRGR") team that validates models to verify they are conceptually sound, computationally accurate, are performing as expected, and are in line with their intended use. MRGR also enforces the company’s model risk governance program that defines roles and responsibilities, including the authority to levy findings requiring remediation and to restrict model usage.
Model Validation
MRGR is independent of both the developers and users of the models. The team validates models through an evaluation process that assesses the data, theory, implementation, outcomes, and governance of each scenario. MRGR assigns each model a model risk score which determines the frequency and scope of each validation. Validations comprise an assessment of model performance as well as a model’s potential limitations given its particular assumptions or weaknesses. Based on the results of the review, the team determines the use case for the model. The ultimate validation results may require remediation actions from the business line. MRGR communicates their result as one of the following three outcomes: “Approved for use”, “Approved with findings”, or “Unapproved”.
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 report, 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.

Words such as “anticipates,” “believes,” “estimates,” “expects,” “forecasts,” “plans,” “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, and ability to treat or prevent further outbreak of, the COVID-19 pandemic, 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.

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 2021 Form 10-K filed with the Securities and Exchange Commission, which contains audited financial statements. Amounts presented as of December 31, 2021 have been derived from the audited financial statements included in BOK Financial’s 2021 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-month period ended June 30, 2022 are not necessarily indicative of the results that may be expected for the year ending December 31, 2022.
Newly Adopted and Pending Accounting Policies
Financial Accounting Standards Board (“FASB”)
FASB Accounting Standards Update No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ("ASU 2020-04")
On March 12, 2020, the FASB issued ASU 2020-04 which provides optional expedients and exceptions for applying U.S. GAAP to contract modifications and hedging relationships that reference LIBOR or another reference rate expected to be discontinued, subject to meeting certain criteria. Under the new guidance, an entity can elect by accounting topic or industry subtopic to account for the modification of a contract affected by reference rate reform as a continuation of the existing contract, if certain conditions are met. In addition, the new guidance allows an entity to elect on a hedge-by-hedge basis to continue to apply hedge accounting for hedging relationships in which the critical terms change due to reference rate reform, if certain conditions are met. A one-time election to sell and/or transfer held-to-maturity debt securities that reference a rate affected by reference rate reform is also allowed. ASU 2020-04 became effective for all entities as of March 12, 2020 and will apply to all LIBOR reference rate modifications through December 31, 2022. Adoption of ASU 2020-04 did not have a material impact on the Company's financial statements.
FASB Accounting Standards Update No. 2021-01, Reference Rate Reform (Topic 848): Scope ("ASU 2021-01")
On January 7, 2021, the FASB issued ASU 2021-01 which clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The amendments in this update are elective and apply to all entities that have derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. The amendments also optionally apply to all entities that designate receive-variable rate, pay-variable-rate cross-currency interest rate swaps as hedging instruments in net investment hedges that are modified as a result of reference rate reform. ASU 2021-01 is effective immediately for all entities and amendments may be applied on a full retrospective basis as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020. Adoption of ASU 2021-01 did not have a material impact on the Company's financial statements.

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 is effective for fiscal years beginning after December 15, 2022 and amendments related to TDR recognition and measurement may be applied using either a prospective or modified retrospective transition method, while amendments on TDR and vintage disclosures are to be adopted prospectively. Management is currently evaluating the impact of ASU 2022-02 on the Company's financial statements.

During the three months ended June 30, 2022, the Company transferred certain U.S. government agency mortgage-backed securities from the available for sale portfolio to the investment securities portfolio (held-to-maturity) as the Company has the positive intent and ability to hold these securities to maturity. No gains or losses were recognized in the Consolidated Statements of Earnings at the time of the transfer. Transfers of debt securities into the investment securities portfolio (held-to-maturity) are made at fair value at the date of transfer. The unrealized holding gain or loss at the date of transfer is retained in accumulated other comprehensive income and in the carrying value of the investment securities portfolio. Such amounts are amortized over the estimated life of the security as an adjustment to yield, offsetting the related amortization of the premium or accretion of the discount on the transferred securities. At the time of transfer, the fair value totaled $2.4 billion, amortized cost totaled $2.7 billion and the pretax unrealized loss totaled $268 million.
The amortized cost and fair values of investment securities at June 30, 2022, by contractual maturity, are as shown in the following table (dollars in thousands):

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):

|  | June 30, 2022 |  | December 31, 2021

(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 reduced 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.
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.
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.
Loans to borrowers experiencing financial difficulties may be modified in troubled debt restructurings ("TDRs"). Primarily all TDRs are classified as nonaccruing, excluding loans guaranteed by U.S. government agencies. Modifications generally consist of extension of payment terms or interest rate concessions and may result 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 is not voluntarily forgiven.
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 TDR. The charge-off amount is determined through a quarterly evaluation of available cash resources and collateral value. 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 TDRs 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.
Portfolio segments of the loan portfolio are as follows (in thousands):

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, 2022, outstanding commitments totaled $13.5 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.
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, 2022, outstanding standby letters of credit totaled $701 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-going 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.
- 64 -

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.
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, third 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 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 percent 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 percent of the committed dollars in the portfolio is calculated using charge-off migration.
The expected credit loss on approximately 1 percent 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 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.
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.

Changes in our reasonable and supportable forecasts of macroeconomic variables resulted in a $305 thousand provision for credit losses related to lending activities during the second quarter of 2022. An increase in required provision due to loan growth and changes in our economic outlook was offset by a sustained trend of improving credit quality metrics. Changes in the loan portfolio characteristics, including specific impairment and losses, loan balances, risk grading and changes in payment profile resulted in a $458 thousand negative provision for credit losses related to lending activities.

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 identified 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.
- 68 -

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 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):

Residential Mortgage Servicing
Mortgage servicing rights may be originated or purchased. Both originated and purchased mortgage servicing rights are initially recognized at fair value. The Company has elected to carry all mortgage servicing rights at fair value. Changes in the fair value are recognized in earnings as they occur. The unpaid principal balance of loans serviced for others is the primary driver of servicing revenue.
The following represents a summary of mortgage servicing rights (dollars in thousands):

|  | June 30, 2022 |  | December 31, 2021
Number of residential mortgage loans serviced for others |  | 113,217 |  |  | 102,008 |
Outstanding principal balance of residential mortgage loans serviced for others |  | $ | 19,327,944 |  |  | $ | 16,442,446 |

Ending Balance |  | $ | 270,312 |  |  | $ | 117,629 |  |  | $ | 270,312 |  |  | $ | 117,629 |

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:

|  | June 30, 2022 |  | December 31, 2021
Discount rate – risk-free rate plus a market premium |  | 8.77% |  | 8.39%
Prepayment rate - based upon loan interest rate, original term and loan type |  | 7.88% |  | 12.11%
Loan servicing costs – annually per loan based upon loan type: |  |  |  |
Performing loans |  | $69 - $94 |  | $69 - $94
Delinquent loans |  | $150 - $500 |  | $150 - $500
Loans in foreclosure |  | $1,000 - $4,000 |  | $1,000 - $4,000
Escrow earnings rate – indexed to rates paid on deposit accounts with comparable average life |  | 3.05% |  | 1.32%
Primary/secondary mortgage rate spread |  | 105 bps |  | 105 bps
Delinquency rate |  | 1.87% |  | 2.05%

Changes in primary residential mortgage interest rates directly affect the prepayment speeds used in valuing our mortgage servicing rights. A separate third 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
On June 24, 2015, BOKF, NA received a complaint that an employee had colluded with a bond issuer and an individual in misusing revenues pledged to municipal bonds for which BOKF, NA served as trustee under the bond indenture. The Company conducted an investigation and concluded that employees in one of its Corporate Trust offices had, with respect to a single group 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, the Securities and Exchange Commission ("SEC"). On September 7, 2016, BOKF, NA agreed, and the SEC entered, a consent order finding that BOKF, NA had violated Section 17(a) of the Securities Act of 1933 and Section 10(b) of the Securities Exchange Act and requiring BOKF, NA to disgorge $1,067,721 of fees and pay 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. The action remains stayed with no current deadlines pending. 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. The Tulsa County District Court recently granted in part and denied in part BOKF, NA’s motion to dismiss the plaintiffs’ Third Amended Petition and BOKF is preparing to respond. Management is advised by counsel that, in the Tulsa County District Court action, a loss is not probable and that the loss, 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 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 $20 million 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 Company in the event a loss to the Company becomes probable.
As previously reported, the United States Courts of Appeals for the Fifth and the Tenth Circuits have each affirmed dismissals of putative class actions in which the plaintiffs alleged that an extended overdraft fee charged by BOKF, NA was impermissible interest. The time within which any appeals of such dismissals may be filed has expired and the actions successfully concluded.
On March 7, 2020, three former employees sued BOKF, NA, the Plan Committee of the BOKF, NA 401k Plan, and Cavanal Hill Investment Management, Inc., a subsidiary of BOKF, NA, alleging that the defendants included proprietary investment products as investment options in the BOKF, NA 401k Plan, whose fees were too high and performance too low, for the purpose of earning fees. The action is brought as a putative class action on behalf of all Plan Participants. The District Court for the Northern District of Oklahoma denied the defendants' motion to dismiss and the action is proceeding. Management is advised by counsel that a loss is not probable and that the loss, if any, cannot be reasonably estimated.
In 2019, a limited liability partnership sued BOKF, NA in Colorado District Court alleging that the Bank breached various fiduciary duties as trustee of a trust that was a co-general partner of the partnership and claiming in excess of $60 million in damages. From 2000 to 2009, BOKF was serving as personal representative of the estate of the creator of the trust. In 2009, BOKF moved to close the probate of the estate in the Colorado Probate Court. The members of the partnership who now sue BOKF objected to the closing of the estate and made the same allegations in the 2009 probate hearing as they now make in the 2019 Colorado District Court action. In 2009, the Colorado Probate Court entered summary judgment against the beneficiaries and the estate was closed. The 2019 action is pending on BOKF’s renewed motions for summary judgment. Management is advised by counsel that a loss is not probable and that the loss, if any, cannot be reasonably estimated.
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.
Alternative Investment Commitments
The Company sponsors a private equity fund and invests in several tax credit entities and other funds as permitted by banking regulations. Consolidation of these investments is based on the variable interest model.
- 79 -

At June 30, 2022, the Company has $374 million in interests in various alternative investments generally consisting of unconsolidated limited partnership interests in entities for which investment return is in the form of low income housing tax credits or other investments in merchant banking activities. This investment balance also includes $92 million of unfunded commitments included in Other liabilities on the Consolidated Balance Sheets.
(7) Shareholders' Equity
On August 2, 2022, the Company declared a quarterly cash dividend of $0.53 per common share payable on or about August 25, 2022 to shareholders of record as of August 16, 2022.
Dividends declared were $0.53 and $1.06 per share during the three and six months ended June 30, 2022 and $0.52 and $1.04 per share during the three and six months ended June 30, 2021.
Accumulated Other Comprehensive Income (Loss)
AOCI includes unrealized gains and losses on available for sale ("AFS") securities. AOCI also includes unrealized losses on AFS securities that were transferred from AFS to investment securities in the second quarter of 2022. Such amounts are being amortized over the estimated remaining life of the security as an adjustment to yield, offsetting the related amortization of premium on the transferred securities. Unrealized losses on employee benefit plans will be reclassified into income as pension plan costs are recognized over the remaining service period of plan participants. Gains and losses in AOCI are net of deferred income taxes.

(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. 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.
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 six months ended June 30, 2022 and 2021, respectively. Transfers between significant other observable inputs and significant unobservable inputs during the six months ended June 30, 2022 and 2021 are included in the summary of changes in recurring fair values measured using unobservable inputs.
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, 2022 or December 31, 2021.

1 Residential 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 95.07% of the unpaid principal balance.
2 A 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.

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, 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, 2022 for which the fair value was adjusted during the six months ended June 30, 2022:

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.
