The Company uses a fair value hierarchy to measure fair value. This hierarchy describes three levels of inputs that may be used to measure fair value: Level 1: Quoted prices for identical assets in active markets that are identifiable on the measurement date; Level 2: Significant other observable inputs, such as quoted prices for similar assets, quoted prices in markets that are not active and other inputs that are observable or can be corroborated by observable market data; and Level 3: Significant unobservable inputs that reflect the Company’s own view about the assumptions that market participants would use in pricing an asset.

Debt securities: The fair values of securities available for sale are determined by matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities, but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs).

Equity securities: The Company’s equity securities are not actively traded in an open market. The fair value of these equity security available for sale not actively traded in an open market is determined by using market data inputs for similar securities that are observable (Level 2 inputs).

The fair value of the swap asset/liability: The fair value of the swap asset and liability is based on an external derivative model using data inputs based on similar transactions as of the valuation date and classified Level 2. The changes in fair value of these assets/liabilities had no impact on net income or comprehensive income.

Mortgage servicing rights: Mortgage servicing rights do not trade in an active market with readily observable market data. As a result, the Company estimates the fair value of mortgage servicing rights by using a discounted cash flow model to calculate the present value of estimated future net servicing income. The Company stratifies its mortgage servicing portfolio on the basis of loan type. The assumptions used in the discounted cash flow model are those that the Company believes market participants would use in estimating future net servicing income. Significant assumptions in the valuation of mortgage servicing rights include estimated loan repayment rates, the discount rate, servicing costs, and the timing of cash flows, among other factors. Mortgage servicing rights are classified as Level 3 measurements due to the use of significant unobservable inputs, as well as significant management judgment and estimation.

Impaired loans: The Company has measured impairment on impaired loans based on the discounted cash flows of the loan or the fair value of the loan’s collateral. Fair value is generally determined based upon independent third-party appraisals of the properties. In some cases, management may adjust the appraised value due to the age of the appraisal, changes in market conditions, or observable deterioration of the property since the appraisal was completed. Additionally, management makes estimates about expected costs to sell the property which are also included in the net realizable value. If the fair value of the collateral dependent loan is less than the carrying amount of the loan, a specific reserve for the loan is made in the allowance for loan losses or a charge-off is taken to reduce the loan to the fair value of the collateral (less estimated selling costs) and the loan is included as a Level 3 measurement. If the fair value of the collateral exceeds the carrying amount of the loan, then the loan is not included in the table below as it is not currently being carried at its fair value.

Assets and liabilities measured at fair value are summarized in the table below.
