BancFirst’s loans are mostly to customers within Oklahoma and approximately 58% of the 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. BancFirst’s commercial and agricultural non-real estate and oil and gas loan categories include upstream and midstream energy loans and loans to companies that provide ancillary services to the energy industry, such as transportation, preparation contractors and equipment manufacturers. The balance of these upstream energy loans was approximately $191 million at December 31, 2020 and approximately $189 million at December 31, 2019. The balance of midstream energy loans was approximately $50 million at December 31, 2020 and approximately $41 million at December 31, 2019. The balance of the ancillary services energy loans was approximately $59 million at December 31, 2020 and approximately $90 million at December 31, 2019. Pegasus Bank’s loans are mostly to customers within Texas and approximately $272 million or 49% of the loans are secured by real estate at December 31, 2020. Pegasus Bank’s commercial and agricultural non-real estate loans were approximately $262 million at December 31, 2020, and approximately $172 million at December 31, 2019. Pegasus Bank’s commercial and agricultural non-real estate loan category includes upstream energy loans and loans to companies that provide ancillary services to the energy industry, such as transportation, preparation contractors and equipment manufacturers. The balance of upstream energy loans was approximately $107 million at December 31, 2020 and approximately $57 million at December 31, 2019. The balance of midstream energy loans was approximately $11 million at December 31, 2020 and zero at December 31, 2019. The balance of the ancillary services energy loans was approximately $13 million at December 31, 2020 and approximately $7 million at December 31, 2019. As of December 31, 2020, the Company had $652.7 million in PPP loans held for investment, net of unamortized processing fees of $14.5 million. Through December 31, 2020, $15.6 million of processing fees were recognized as interest income. Troubled Debt Restructurings, Other Real Estate Owned and Repossessed Assets and Held for Sale Assets The following is a summary of troubled debt restructurings and other real estate owned and repossessed assets:

Other real estate owned and repossessed assets |  | $ | 32,480 |  |  | $ | 6,073 |
The Company charges interest on principal balances outstanding on troubled debt restructurings during deferral periods. The current and future financial effects of the recorded balance of loans considered to be troubled debt restructurings were not considered to be material. During 2020, the Company sold property held in other real estate owned for a total gain of $2.4 million compared to gains of $1.4 million in 2019 and $23,500 in 2018. At December 31, 2020, the Company’s principal subsidiary bank, BancFirst, had approximately $21.6 million in loans at its Hugo, Oklahoma branch that it has entered into an agreement to sell to AmeriState Bank in Atoka, Oklahoma. Accordingly, as of December 31, 2020, the Company has transferred $21.6 million from loans held for investment (net of unearned interest) to loans held for sale. Nonaccrual loans Had nonaccrual loans performed in accordance with their original contractual terms, the Company would have recognized additional interest income of approximately $2.8 million in 2020, $1.7 million in 2019 and $2.3 million in 2018. Approximately $7.8 million of nonaccrual loans are guaranteed by government agencies as of December 31, 2020.

Due to the impacts of the COVID-19 pandemic, the Company has approximately $81.7 million in modified loans, most of which are secured by commercial real estate, as of December 31, 2020. These modifications were undertaken in response to Section 4013 of the CARES Act and the regulatory intent outlined in the Interagency Statement on Loan Modifications by Financial Institutions Working with Customers Affected by the Coronavirus and to provide businesses financial flexibility until the economy has time to recover to a more normal level of activity. However, these modifications, which typically involve payment modifications and forbearance, also have the effect of delaying recognition of loans that may ultimately be permanently impaired. The timing and extent of such consequences are difficult to ascertain at this time and are dependent on the duration of the COVID-19 pandemic, the level and success of the government’s economic stimulus, and further regulatory guidance. These modified loans are included in current loans in the table above as of December 31, 2020. BancFirst 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. 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 BancFirst’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. Pegasus Bank Credit Quality Indicators Pegasus Bank categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, including current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. Pegasus Bank analyzes loans individually by classifying the loans as to credit risk. Pegasus Bank uses the following definitions for risk ratings: Pass – Loans classified as a pass are loans with low to average risk. These loans are included in grade 1 and 2 for the purposes for the following table: Special Mention – Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of Pegasus Bank’s credit position at some future date. These loans are included in grade 3 for the purposes of the following table: Substandard – Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Pegasus Bank will sustain some loss if the deficiencies are not corrected. These loans are included in grade 4 for the purposes of the following table: Doubtful – Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. These loans, if any, would be included in grade 5 for the purposes of the following table: The Company’s revolving loans that are converted to term loans are not material and therefore have not been presented. The following table summarizes our gross loans held for investment by year of origination and internally assigned credit grades:

Allowance for Credit Losses Methodology On January 1, 2020, the Company adopted ASC 326, which replaces the incurred loss methodology for determining its provision for credit losses and allowance for credit losses with an expected loss methodology that is referred to as the CECL model. See Note (1) for additional information regarding the factors that influenced the Company’s current estimate of expected credit losses. Upon adoption, the allowance for credit losses was decreased by $3.2 million, with no impact to the consolidated statement of income. Subsequent to the adoption of ASC 326, the Company recorded a $62.6 million provision for credit losses for year ended December 31, 2020 utilizing the newly adopted CECL methodology, a significant increase from the year ended December 31, 2019. The increase resulted primarily from the anticipated impact on our loan portfolio resulting from the economic outlook related to the COVID-19 pandemic and the decline in energy prices and to a lesser degree, loan growth during 2020. Prolonged low energy prices will not only have a direct impact on the energy portfolio; it will have an indirect effect on the economies of Oklahoma and the Dallas, Texas market, including higher unemployment, with a residual effect on land values and real estate prices. 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.
|  | Allowance for Credit Losses |
|  | Balance at beginning of period |  |  | Impact of CECL adoption |  |  | Initial allowance on loans purchased with credit deterioration |  |  | Charge- offs |  |  | Recoveries |  |  | Net charge-offs |  |  | Provision for credit losses on loans |  |  | Balance at end of period |

Impaired Loans Prior to the adoption of ASC 326, loans were considered impaired when, based on current information and events, it was probable the Company would be unable to collect the full amount of scheduled principal and interest payments in accordance with the original contractual terms of the loan agreement. If a loan was impaired, a specific valuation allowance may be allocated, if necessary, so that the loan was reported, net of allowance for credit loss, at the present value of future cash flows using the loan’s existing rate, or the fair value of collateral if repayment was expected solely from the collateral. During the year ended December 31, 2019 no material amount of interest income was recognized on impaired loans subsequent to their classification as impaired. The following table presents impaired loans, segregated by class of loans.
