At December 31, 2022, loans to businesses and individuals with collateral primarily located in Texas totaled $7.3 billion or 32% of the total loan portfolio. Loans to businesses and individuals with collateral primarily located in Oklahoma totaled $3.5 billion or 16% of our total loan portfolio. Loans to businesses and individuals with collateral primarily located in Colorado totaled $2.5 billion or 11% of our total loan portfolio. Loans for which the collateral location is not relevant, such as unsecured loans and reserve-based energy loans, are distributed by the borrower’s primary operating location. These geographic concentrations subject the loan portfolio to the general economic conditions within these areas.

At December 31, 2021, loans to businesses and individuals with collateral primarily located in Texas totaled $6.8 billion or 34% of the loan portfolio, loans to businesses and individuals with collateral primarily located in Oklahoma totaled $3.2 billion or 16% of the loan portfolio and loans to businesses and individuals with collateral primarily located in Colorado totaled $2.5 billion or 12% of the loan portfolio.
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. Commercial loans are underwritten individually and represent on-going 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, interest 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 on-going cash flow from operations of the customer’s business. Inherent lending risk is centrally monitored on a continuous basis from underwriting throughout the life of the loan for compliance with commercial lending policies.

At December 31, 2022, commercial loans with collateral primarily located in Texas totaled $4.7 billion or 33% of the commercial loan portfolio segment. Commercial loans with collateral primarily located in Oklahoma totaled $2.1 billion or 15% of the commercial loan portfolio segment. Commercial loans with collateral primarily located in Colorado totaled $1.8 billion or 12% of the commercial loan portfolio segment. The commercial loan portfolio segment is further divided into loan classes. The services loan class totaled $3.4 billion or 15% of total loans. Approximately $1.6 billion of loans in the services class consisted of loans with individual balances of less than $10 million. Businesses included in the services class include Native American tribal and state and local municipal government entities, Native American tribal casino operations, educational services, foundations and not-for-profit organizations and specialty trade contractors. The energy loan class totaled $3.4 billion or 15% of total loans, including $2.7 billion of outstanding loans to energy producers. Approximately 72% of the committed production loans are secured by properties primarily producing oil and 28% of the committed production loans are secured by properties primarily producing natural gas. The healthcare loan class totaled $3.8 billion or 17% of total loans. The healthcare loan class consists primarily of loans for the development and operation of senior housing and care facilities, including independent living, assisted living and skilled nursing. Healthcare also includes loans to hospitals and other medical service providers.

At December 31, 2021, commercial loans with collateral primarily located in Texas totaled $4.4 billion or 35% of the commercial loan portfolio segment, commercial loans with collateral primarily located in Oklahoma totaled $1.7 billion or 13% of the commercial loan portfolio segment and commercial loans with collateral primarily located in Colorado totaled $1.6 billion or 13% of the commercial loan portfolio segment. The services loan class totaled $3.4 billion or 17% of total loans. Approximately $1.7 billion of loans in the services category consisted of loans with individual balances of less than $10 million. The energy loan class totaled $3.0 billion or 15% of total loans, including $2.2 billion of outstanding loans to energy producers. At December 31, 2021, approximately 67% of committed production loans were secured by properties primarily producing oil and 33% were secured by properties producing natural gas. The healthcare loan class totaled $3.4 billion or 17% of total loans.

Commercial Real Estate

Commercial real estate loans are for the construction of buildings or other improvements to real estate and property held by borrowers for investment purposes primarily 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.

At December 31, 2022, 30% of commercial real estate loans were secured by properties primarily located in the Dallas and Houston metropolitan areas of Texas and 9% of commercial real estate loans were secured by properties located primarily in the Tulsa and Oklahoma City metropolitan areas of Oklahoma. At December 31, 2021, 30% of commercial real estate loans are secured by properties primarily located in the Dallas and Houston metropolitan areas of Texas and 12% of commercial real estate loans were secured by properties located primarily in the Tulsa and Oklahoma City metropolitan areas of Oklahoma.
Paycheck Protection Program
BOK Financial 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 the 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%. 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 December 31, 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. Personal loans consist primarily of loans to Wealth Management clients secured by the cash surrender value of insurance policies and marketable securities. Personal loans also include direct loans secured by and for the purchase of automobiles, recreational and marine equipment as well as unsecured loans. These loans are made in accordance with underwriting policies we believe to be conservative and are fully documented. Loans may be individually underwritten or credit scored based on size and other criteria. Credit scoring is assessed based on significant credit characteristics including credit history, residential and employment stability.

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

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

Approximately 91% of the loans in this segment are secured by collateral located within our geographical footprint. Loans for which the collateral location is less relevant, such as unsecured loans are categorized by the borrower’s primary location.

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 December 31, 2022, outstanding commitments totaled $15.4 billion. Because some commitments are expected to expire before being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. BOK Financial uses the same credit policies in making commitments as it does loans.

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

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 December 31, 2022, outstanding standby letters of credit totaled $740 million. 
Allowances for Credit Losses and Accrual for Off-balance Sheet Credit Risk from Unfunded Loans Commitments

BOK Financial maintains an allowance for loan losses and accrual for off-balance sheet credit risk from unfunded commitments. The allowance 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 based on probability of default, loss given default and exposure at default for each loan class developed based on current and forecasted relevant economic loss drivers.

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 cancellable by the bank.

The activity in the allowance for loan losses and the allowance for off-balance sheet credit losses related to loan commitments and standby letters of credit for the year ended December 31, 2022 is summarized as follows (in thousands):

A $30.0 million provision for credit losses was recorded for the year ended December 31, 2022, primarily due to strong growth in loans and loan commitments, partially offset by improvement in credit quality metrics. The uncertainty in our economic forecast increased resulting in an increase in the probability weighting of the downside scenario. In addition, some key economic factors were less favorable to growth across all scenarios.

Credit Quality Indicators

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

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

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

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

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

Probability of default is lowest for pass graded loans and increases for each credit quality indicator, Special Mention, and Accruing Substandard.
Vintage represents the year of origination, except for revolving loans which are considered in aggregate. Loans that were once revolving but have converted to term loans without additional underwriting appear in a separate vintage column.
