6. FAIR VALUE MEASUREMENTS

The Company utilizes fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Securities available-for-sale and trading securities are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets on a non-recurring basis, such as loans held-for-sale, loans held-for-investment and certain other assets. These non-recurring fair value adjustments typically involve application of lower of cost or market accounting or write-downs of individual assets. Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally corresponds with the Company's quarterly valuation process.

There were no liabilities measured at fair value on a recurring or non-recurring basis at June 30, 2018 and December 31, 2017.

Key methods and assumptions used in measuring the fair value of impaired loans and loan servicing rights as of June 30, 2018 and December 31, 2017 were as follows:

	Method	Assumption Inputs

Impaired loans	Collateral, market, income, enterprise, liquidation and discounted Cash Flows	External appraised values, management assumptions regarding market trends or other relevant factors; selling costs ranging 6% to 7%.

The following section describes the valuation methodologies used for assets recorded at fair value.

Investment Securities Available-for-Sale

Investment securities available-for-sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted market prices, if available. If quoted market prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security's credit rating, prepayment assumptions, and other factors such as credit loss assumptions. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets and money market funds. Level 2 securities include mortgage-backed securities issued by government sponsored entities, municipal bonds and corporate debt securities. Securities classified as Level 3 include asset-backed securities in less liquid markets where valuations include significant unobservable assumptions.

Impaired Loans

The Company does not record loans at fair value on a recurring basis. However, from time to time, a loan is considered impaired and an allowance for loan losses is established. Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. Once a loan is identified as individually impaired, the Company measures impairment. The fair value of impaired loans is estimated using one of several methods, including collateral value, market value of similar debt, enterprise value, liquidation value and discounted cash flows. Inputs include external appraised values, management assumptions regarding market trends or other relevant factors, selling and commission costs generally ranging from 6% to 7%, and amount and timing of cash flows based upon current discount rates. Those impaired loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans.

At June 30, 2018, certain impaired loans were considered collateral dependent and were evaluated based on the fair value of the underlying collateral securing the loan. Impaired loans where an allowance is established based on the fair value of collateral require classification in the fair value hierarchy. When a loan is evaluated based on the fair value of the underlying collateral securing the loan, the Company records the impaired loan as non-recurring Level 3.

Limitations

Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company's entire holdings of a particular financial instrument. Because no market exists for a significant portion of the Company's financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

Fair value estimates are based on existing on- and off-balance sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Other significant assets and liabilities that are not considered financial assets or liabilities include deferred tax liabilities and premises and equipment. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in many of the estimates.
