Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values:

Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.

Level 2 – Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

Level 3 – Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.

The Company used the following methods and significant assumptions to estimate fair value:

Marketable Securities: The fair values for marketable securities are determined by quoted market prices, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators (Level 3).

Loans Held For Sale: Loans held for sale are carried at the lower of cost or fair value, which is evaluated on a pool-level basis. The fair value of loans held for sale is determined using quoted prices for similar assets, adjusted for specific attributes of that loan or other observable market data, such as outstanding commitments from third party investors (Level 2).

Derivative Instruments: The fair values of derivatives are based on valuation models using observable market data as of the measurement date (Level 2).

Impaired Loans: For the year ended December 31, 2019, the fair value of impaired loans with specific allocations of the allowance for loan losses is generally based on the present value of estimated future cash flows using the loan’s existing rate or, if repayment is expected solely from the collateral, the fair value of collateral, less costs to sell. The fair value of real estate collateral is determined using recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches, including the comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant (Level 3). Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business (Level 3). Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly.

Individually Evaluated Collateral Dependent Loans: For the year ended December 31, 2020, the fair value of individually evaluated collateral dependent loans is generally based on the fair value of collateral, less costs to sell. The fair value of real estate collateral is determined using recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant (Level 3). Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business (Level 3).

Other Real Estate Owned: Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. Fair value is commonly based on recent real estate appraisals which are updated no less frequently than annually. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Real estate owned properties are evaluated on a quarterly basis for additional impairment and adjusted accordingly (Level 3).

There were no transfers between Level 2 and Level 3 during the years ended December 31, 2020 or 2019.

Nonfinancial Assets and Nonfinancial Liabilities: Nonfinancial assets measured at fair value on a nonrecurring basis during the years ended December 31, 2020 and 2019 include certain foreclosed assets which, upon initial recognition, were remeasured and reported at fair value through a charge-off to the allowance for loan losses and certain foreclosed assets which, subsequent to their initial recognition, were remeasured at fair value through a write-down included in

current earnings. The fair value of a foreclosed asset is estimated using Level 2 inputs based on observable market data or Level 3 inputs based on customized discounting criteria.

The following table presents foreclosed assets that were remeasured and recorded at fair value as of December 31:

The methods and assumptions, not previously presented, used to estimate fair values are described as follows:

Cash and Cash Equivalents: The carrying amounts of cash and short-term instruments approximate fair values (Level 1).

Loans, net: The fair value of fixed-rate loans and variable-rate loans that reprice on an infrequent basis is estimated by discounting future cash flows using the current interest rates at which similar loans with similar terms would be made to borrowers of similar credit quality (Level 3).

Cash Surrender Value of Life Insurance: The carrying amounts of bank-owned life insurance approximate their fair value.

Nonmarketable Equity Securities: It is not practical to determine the fair value of Independent Bankers Financial Corporation, Federal Home Loan Bank, Federal Reserve Bank of Dallas and other stock due to restrictions placed on its transferability.

Deposits and Securities Sold Under Repurchase Agreements: The fair values disclosed for demand deposits (e.g., interest and non-interest checking, passbook savings, and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amount) (Level 1). The fair values of deposit liabilities with defined maturities are estimated by discounting future cash flows using interest rates currently offered for deposits of similar remaining maturities (Level 2).

Other Borrowings: The fair value of borrowings, consisting of lines of credit, Federal Home Loan Bank advances and Subordinated debentures is estimated by discounting future cash flows using currently available rates for similar financing (Level 2).

Accrued Interest Receivable/Payable: The carrying amounts of accrued interest approximate their fair values (Level 2).
