 financial statements. The preparation of financial statements in conformity with accounting principles generally accepted in the United States inherently involves the use of estimates and assumptions, which affect the amounts reported in the financial statements and the related disclosures. These estimates relate principally to the allowance for credit losses, income taxes, intangible assets and the fair value of financial instruments. Such estimates and assumptions may change over time and actual amounts realized may differ from those reported. The following is a summary of the accounting policies and estimates that management believes are the most critical.

Allowance for Credit losses

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 allowance for credit losses is increased by provisions charged to operating expense and is reduced by net loan charge-offs. The amount of the allowance for credit losses is measured using relevant information about past events, including historical credit loss experience on financial assets with similar risk characteristics, current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the financial assets.

To estimate expected losses using historical loss information, 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 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
