Securities Interest income includes amortization of purchase premiums and accretion of discounts. Premiums and discounts on securities are amortized or accreted on the level-yield method without anticipating prepayments, except for mortgage-backed securities where prepayments are anticipated. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. Declines in the fair value of debt securities below their amortized cost that are other-than-temporary impairment (“OTTI”) are reflected in earnings or other comprehensive income, as appropriate.

Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold, which is reduced by the cost allocated to the servicing right. We generally lock in the sale price to the purchaser of the loan at the same time we make an interest rate commitment to the borrower. These mortgage banking activities are not September 30, 2021, December 31, 2020, Mortgage Banking Activities Servicing fee income is recorded for fees earned for servicing mortgage loans.

COMMITMENTS AND OFF-BALANCE SHEET RISK Our bank is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers.

Fair Value Measurement and Measurement Inputs, Recurring and Nonrecurring [Text Block]	11. FAIR VALUES Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability, or in the absence of a principal market, the most advantageous market for the asset or liability. The price of the principal (or most advantageous) market used to measure the fair value of the asset or liability is not not We are required to use valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement cost). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability.

We generally lock in the sale price to the purchaser of the loan at the same time we make an interest rate commitment to the borrower.

If hedge accounting does not If designated as a hedge, we formally document the relationship between the derivatives and hedged items, as well as the risk-management objective and the strategy for undertaking hedge transactions. This documentation includes linking cash flow hedges to specific assets and liabilities on the balance sheet. If designated as a hedge, we also formally assess, both at the hedge’s inception and on an ongoing basis, whether the derivative instruments that are used are highly effective in offsetting changes in cash flows of the hedged items.
