18. Fair Value of Financial Instruments

U.S. GAAP requires disclosure of fair value information about financial instruments, whether or not recognized on the balance sheet, for which it is practical to estimate that value. The estimated fair value amounts have been determined by the Company using available market information and appropriate valuation methodologies. The use of assumptions and various valuation techniques, as well as the absence of secondary markets for certain financial instruments, will likely reduce the comparability of fair value disclosures between financial institutions. In some cases, book value is a reasonable estimate of fair value due to the relatively short period of time between origination of the instrument and its expected realization. The valuation of loans held for investment was impacted by the adoption of ASU 2016-01. In accordance with ASU 2016-01, the fair value of loans held for investment, excluding previously presented impaired loans measured at fair value on a non-recurring basis, is estimated using discounted cash flow analyses. The discount rates used to determine fair value use interest rate spreads that reflect factors such as liquidity, credit, and nonperformance risk of the loans. Loans are considered a Level 3 classification.

The following tables summarize the book value and estimated fair value of financial instruments for the periods indicated:
