Certain loan segments for 2022 were reclassified to conform to the 2023 presentation. Each loan segment consists of loan categories possessing similar risk characteristics. The Company’s re-alignment of the segments primarily consisted of reclassifying farmland and agriculture related loans that were previously included in consumer-related and commercial-related loans to the agriculture category. Management believes this accurately represents the risk profile of each loan segment. These reclassifications did not have a significant impact on the allowance for credit losses. The Company's loans are currently 84% held by BancFirst and 16% held by Pegasus and Worthington. In addition, approximately 69% of the Company's loans are secured by real estate. Credit risk on loans is managed through limits on amounts loaned to individual and related borrowers, underwriting standards and loan monitoring procedures. The amounts and types of collateral obtained, if any, to secure loans are based upon the Company’s underwriting standards and management’s credit evaluation. Collateral varies, but may include real estate, equipment, accounts receivable, inventory, livestock and securities. The Company’s interest in collateral is secured through filing mortgages and liens, and in some cases, by possession of the collateral. The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist. The Company has identified the following portfolio segments, which includes the applicable weighted average remaining life, and measures the allowance for credit losses using the vintage loss analysis adjusted for qualitative factors:
Portfolio Segments |  | Life (in years) |
Real estate: |  |  |
Commercial real estate owner occupied |  |  | 9 |
Commercial real estate non-owner occupied |  |  | 6 |

Residential real estate first lien |  |  | 15 |
Residential real estate all other |  |  | 8 |
Agriculture |  |  | 9 |
Commercial non-real estate |  |  | 4 |
Consumer non-real estate |  |  | 4 |
Oil and gas |  |  | 2 |
These portfolio segments are separately identified because they exhibit distinctive risk characteristics, such as financial asset types, loan purpose, collateral, and industry of the borrower. A summary of our primary portfolio segments is as follows: Commercial real estate owner occupied. Commercial real estate owner occupied are nonresidential property loans for which the primary source of repayment is the cash flow from the ongoing operations and activities conducted by the entity, or an affiliate of the entity, who owns the property. This category includes, among other loans, loans secured by office buildings, garden office buildings, manufacturing facilities, warehouse and flex warehouse facilities, hospitals, and car washes unless the property is owned by an investor who leases the property to the operator who, in turn, is not related to or affiliated with the investor. Commercial real estate non-owner occupied. Commercial real estate non-owner occupied are nonresidential property loans where the primary source of repayment is derived from rental income associated with the property or the proceeds of the sale, refinancing, or permanent financing of the property. This category includes, among other loans, loans secured by shopping centers, office buildings, hotels/motels, nursing homes, assisted-living facilities, mini-storage warehouse facilities, and similar properties. Construction and development < 60 months. Residential development loans include loans to develop raw land into a residential development. Advances on the loans typically include land costs, hard costs (grading, utilities, roads, etc.), soft costs (engineering fees, development fees, entitlement fees, etc.) and carrying costs until the development is completed. Upon completion of the development, the loan is typically repaid through the sale of lots to homebuilders. Construction residential real estate < 60 months. Residential construction includes loans to builders for speculative or custom homes, as well as direct loans to individuals for construction of their personal residence. Custom construction and self-construction loans typically will have commitments in place for long-term financing at the completion of construction. Speculative construction loans generally will have periodic curtailment plans beginning after completion of construction and a reasonable time for sales to have occurred. Residential real estate first lien. Residential real estate first lien loans includes all closed-end loans secured by first liens on 1-to-4 family residential properties. This category includes property containing 1-to-4 dwelling units (including vacation homes) or more than four dwelling units if each is separated from other units by dividing walls that extend from ground to roof. This category also includes individual condominium dwelling units and loans secured by an interest in individual cooperative housing units, even if in a building with five or more dwelling units. Residential real estate all other. Residential real estate all other loans includes loans secured by junior (i.e., other than first) liens on 1-to-4 family residential properties. This category includes loans secured by junior liens even if the Company also holds a loan secured by a first lien on the same 1-to-4 family residential property. Agricultural. This category includes loans secured by all land known to be used or usable for agricultural purposes, such as crop and livestock production. Commercial non-real estate. Commercial non-real estate represent loans for working capital, facilities acquisition or expansion, purchase of equipment and other needs of commercial customers primarily located within Oklahoma. Loans in this category include commercial and industrial and state and political subdivisions. Consumer non-real estate. Consumer loans are loans to individuals for household, family and other personal expenditures. Commonly, such loans are made to finance purchases of consumer goods, such as automobiles, boats, household goods, vacations and education. Oil and gas. Oil and gas loans represent loans for producing oil and gas properties and any other mineral interests that may be pumped, mined, quarried or otherwise extracted from the earth. These loans also include upstream and midstream energy loans, and loans to companies that provide ancillary services to the energy industry, such as transportation, wellsite preparation contractors and equipment manufacturers.

During 2023, the Company wrote down property held in other real estate owned for a total of $5.2 million compared to write downs of $3.7 million in 2022 and $538,000 in 2021. The Company charges interest on principal balances outstanding on modified loans during deferral periods. The current and future financial effects of the recorded balance of loans considered to be modified during the period were not considered to be material. The recorded balance of modified loans was approximately $5.3 million during the year ended December 31, 2023. Nonaccrual loans The Company did no t recognize any interest income on nonaccrual loans for any of the years ended December 31, 2023, 2022 or 2021. In addition, there were no nonaccrual loans for which there is no related allowance for credit losses at both December 31, 2023 and December 31, 2022. Had nonaccrual loans performed in accordance with their original contractual terms, the Company would have recognized additional interest income of $1.6 million in 2023, $1.3 million in 2022 and $2.2 million in 2021. Nonaccrual loans guaranteed by government agencies totaled $6.7 million at December 31, 2023 and $4.7 million at December 31, 2022.

Credit Quality Indicators The Company considers credit quality indicators to monitor the credit risk in the loan portfolio including volume and severity of loan delinquencies, nonaccrual loans, internal grading of loans, historical credit loss experience and economic conditions. These indicators are reviewed and updated regularly throughout the year. An internal risk grading system is used to indicate the credit risk of loans. The loan grades used by the Company are for internal risk identification purposes and do not directly correlate to regulatory classification categories or any financial reporting definitions. The general characteristics of the risk grades are as follows: Grade 1 – Acceptable - Loans graded 1 represent reasonable and satisfactory credit risk which requires normal attention and supervision. Capacity to repay through primary and/or secondary sources is not questioned. Grade 2 – Acceptable - Increased Attention - This category consists of loans that have credit characteristics deserving management’s close attention. These complexities or potential weaknesses could result in deterioration of the repayment prospects for the loan or the Company's credit position at some future date. Such credit characteristics include loans to highly leveraged borrowers in cyclical industries, adverse financial trends which could potentially weaken repayment capacity, loans that have fundamental structure complexity or deficiencies, loans lacking secondary sources of repayment where prudent, and loans with deficiencies in essential documentation, including financial information. Grade 3 – Loans with Problem Potential - This category consists of performing loans which are considered to exhibit problem potential. Loans in this category would generally include, but not be limited to, borrowers with a weakened financial condition or poor performance history, past dues, loans restructured to reduce payments to an amount that is below market standards and/or loans with severe documentation problems. In general, these loans have no identifiable loss potential in the near future; however, the possibility of a loss developing is heightened. Grade 4 - Problem Loans/Assets – Nonperforming - This category consists of nonperforming loans/assets which are considered to be problems. Nonperforming loans are described as being 90 days and over past due and still accruing, and loans that are nonaccrual. The government guaranteed portion of SBA loans is excluded. Grade 5 - Loss Potential - This category consists of loans/assets which are considered to possess loss potential. While the loss may not occur in the current year, management expects that loans/assets in this category will ultimately result in a loss, unless substantial improvement occurs. Grade 6 - Charge Off - This category consists of loans that are considered uncollectible and other assets with little or no value. The Company’s revolving loans that are converted to term loans are not material and therefore have not been presented. The following tables summarizes the Company's gross loans held for investment by year of origination and internally assigned credit grades:

Allowance for Credit Losses Methodology The Company determines its provision for credit losses and allowance for credit losses using the current expected credit loss methodology that is referred to as the current expected credit loss ("CECL") model. The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist. The Company elected to utilize a methodology known as vintage loss analysis for BancFirst, Pegasus, and Worthington. Vintage loss analysis measures impairment based on the age of the accounts and the historical asset performance of assets with similar risk characteristics. Vintage loss analysis determines expected losses by allowing the Company to calculate the cumulative loss rates of a given loan pool and in so doing, determine the loan pool’s lifetime expected loss experience relative to the appropriate type of financial assets that share similar risk characteristics. Vintage loss analysis uses different “vintages” analyzed by year of origination through the weighted average maturity of each loan pool. The key quantitative inputs used in the Company’s estimate of the allowance for credit losses include 1) all available loan data tracked by year of origination, 2) total charge-offs for each specific loan pool recorded since year of origination, 3) recovery rate calculated by the average recovery over the previous seven years across all loan pools, and 4) a weighting factor biased to more recent loss experience. The quantitative expected credit loss is calculated by dividing each year’s net charge-offs by the original balance. The respective vintage’s original balance remains the denominator in each annual calculation, as it references the specific vintage’s initial balance. The loss experience of this original balance is tracked annually and summed over the life of the loan for each separate loan pool, leaving a cumulative life of credit loss rate based on historic averages weighted towards more recent loss experience. These key quantitative inputs change from period to period as new loans are originated, and charge-offs and recoveries are recognized. The recovery rate is revised on an annual basis, taking into consideration the most recent seven years. The weighting factor percentages remain static, however, the most recent year receives the highest weighting percentage. The BancFirst Senior Loan Committee (“the SLC”) sets BancFirst qualitative adjustments. In setting the qualitative adjustments, they consider several factors, including external economic information, peer bank comparisons and experience with the loan portfolio. The SLC also considers Moody’s Analytics dataset. From this dataset, BancFirst selects a range of 4 probability scenarios from two economic forecasts. To determine the appropriate correlation to our loss experience, BancFirst compares the economic indicators over the past ten years of charge-off history to arrive at a correlation factor. BancFirst then applies the correlation factor to the change in the forecast of the aforementioned economic indicators over the next 18-24 months, which is driven by management’s judgment of a reasonable and supportable forecast period to arrive at a percentage range of qualitative loss adjustment attributable to economic forecasts. The SLC establishes a qualitative adjustment for each loan pool using these factors. For periods beyond which BancFirst is able to make or obtain reasonable and supportable forecasts of expected credit losses, BancFirst reverts to historical loss information. In some cases, management may determine a loan to be collateral dependent. A loan is considered collateral-dependent when the repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty based on the Company's assessment as of the reporting date. For collateral dependent loans, the standard allows institutions to use, as a practical expedient, the fair value of the collateral to measure expected credit losses on collateral-dependent financial assets. This amount is included in the allowance for credit losses. The increase in allowance for credit losses during 2023 was related to loan growth during the year. The increase in allowance for credit losses during 2022 was related to the purchase of loans without credit deterioration during the year along with loan growth. The following table details activity in the allowance for credit losses on loans for the period presented. Allocation of a portion of the allowance to one category of loans does not preclude its availability to absorb losses in other categories.
