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 reporting entity’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 the fair value of each type of financial instrument:

Investment Securities: The Company uses a third party service to estimate fair value on available for sale securities on a monthly basis. The Company’s service provider is considered a leading evaluation pricing service for U.S. domestic fixed income securities and complies fully with ASU 2016-01’s exit pricing requirements. They subscribe to multiple third-party pricing vendors, and supplement that information with matrix pricing methods. The fair values for investment securities, which consist of equity securities that are recorded at fair market value to comply with ASU 2016-01, are determined by quoted market prices in active markets, if available (Level 1). The equity securities change in fair market value is recorded in the income statements. For securities where quoted prices are not available, fair values are calculated based on quoted prices for similar assets in active markets, quoted prices for similar assets in markets that are not active or inputs other than quoted prices, which provide a reasonable basis for fair value determination. Such inputs may include interest rates and yield curves, volatilities, prepayment speeds, credit risks and default rates. Inputs used are derived principally from observable market data (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). The fair values of Level 3 investment securities are determined by using unobservable inputs to measure fair value of assets for which there is little, if any market activity at the measurement date, using reasonable inputs and assumptions based on the best information at

the time, to the extent that inputs are available without undue cost and effort. For the period ended June 30, 2021 and for the year ended December 31, 2020, the fair value of Level 3 investment securities was immaterial.

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

Collateral Dependent Loans: Fair value estimates of collateral dependent loans that are individually reviewed are based on the fair value of the collateral, less estimated costs to sell. Non-collateral dependent loans are valued based on discounted cash flows. Loans carried at fair value generally receive specific allocations of the allowance for credit losses in 2021 and allowance for loan losses in prior periods. For collateral dependent loans, fair value is commonly based on 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 appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. 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, resulting in a Level 3 fair value classification. These loans are evaluated on a quarterly basis and adjusted accordingly.

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 values are commonly based on recent real estate appraisals. These appraisals may use 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 and typically result in a Level 3 classification of the inputs for determining fair value.

Appraisals for both collateral-dependent impaired loans and other real estate owned are performed by certified general appraisers (for commercial and commercial real estate properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by the Company. Once received, a member of the Appraisal Department reviews the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. On an annual basis, the Company compares the actual selling price of collateral that has been sold to the most recent appraised value to determine what adjustments should be made to appraisals to arrive at fair value.

Collateral dependent loans were individually evaluated under ASC 326 for the period ended June 30, 2021, while impaired loans from the period ended December 31, 2020 were individually evaluated under ASC 310. Collateral dependent loans had a principal balance of $5.5 million with a valuation allowance of $1.2 million at June 30, 2021. Impaired loans that were measured for impairment using the fair value of the collateral had a principal balance of $2.3 million, with a valuation allowance of $368 thousand at December 31, 2020. Excluded from the above tables at June 30, 2021 and December 31, 2020, are $591 thousand and $513 thousand of loans classified as troubled debt restructurings and measured using the present value of cash flows, which is not considered an exit price.

Collateral dependent commercial real estate loans, both owner-occupied and non-owner occupied are valued by independent external appraisals. These external appraisals are prepared using the sales comparison approach and income approach valuation techniques. Management makes subsequent unobservable adjustments to the collateral dependent loan appraisals. Collateral dependent loans other than commercial real estate and other real estate owned are not considered material.

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

Cash and Cash Equivalents: The carrying amounts of cash and short-term instruments approximate fair values and are classified as Level 1.

Restricted Stock: It is not practical to determine the fair value of restricted stock due to restrictions placed on its transferability.

Loans: Fair values of loans, excluding loans held for sale, are estimated as follows: The Company uses a third party firm that uses cash flow analysis and current market interest rates along with adjustments for credit, liquidity and option risk to conform to the ASU 2016-01 exit price requirement. Loans in the tables above consist of impaired credits held for investment. Fair value for collateral dependent loans is based upon appraised values adjusted for trends observed in the market, less estimated cost to sell. The cash flow method is used for estimating fair value for noncollateral dependent loans. A valuation allowance was recorded for the excess of the loan’s recorded investment over the amounts determined by the collateral value method. This valuation is a component of the allowance for credit losses. The Company considers these fair values level 3.

Loans held for sale: The fair value of loans held for sale is estimated based upon binding contracts and quotes from third party investors resulting in a Level 2 classification.

Deposits: The fair values disclosed for demand deposits – interest and non-interest checking, passbook savings, and money market accounts – are, by definition, equal to the amount payable on demand at the reporting date resulting in a Level 1 classification. The carrying amounts of variable rate certificates of deposit approximate their fair values at the reporting date resulting in a Level 2 classification. Fair value for fixed rate certificates of deposit are estimated using a discounted cash flows calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits resulting in a Level 2 classification.

Short-term Borrowings: The carrying amounts of federal funds purchased, borrowings under repurchase agreements, and other short-term borrowings, generally maturing within ninety days, approximate their fair values resulting in a Level 2 classification.

Long-term Borrowings: The fair values of the Company’s long-term borrowings are estimated using discounted cash flow analyses based on the current borrowing rates for similar types of borrowing arrangements resulting in a Level 2 classification.

Off-balance Sheet Instruments: The fair value of commitments is not considered material.
