Fair Value Measurement and Measurement Inputs, Recurring and Nonrecurring [Text Block] | 1 2 . Fair Value Measurement s The Company determined the fair values of our financial instruments based on the following:
| ● | Level 1 - Quoted prices in active markets for identical assets or liabilities.
| ● | Level 2 - Observable prices in active markets for similar assets or liabilities; prices for identical or similar assets or liabilities in markets that are not active; directly observable market inputs for substantially the full term of the asset and liability; market inputs that are not directly observable but are derived from or corroborated by observable market data.
| ● | Level 3 – Unobservable inputs based on the Company’s own judgment about the assumptions that a market participant would use.
The Company uses the following methodologies to measure the fair value of its financial assets and liabilities on a recurring basis: Securities Available for Sale . For certain U.S. Treasury securities, the Company measures the fair value based on quoted market prices in active exchange markets at the reporting date, a Level 1 measurement. The Company also measures securities by using quoted market prices for similar securities or dealer quotes, a Level 2 measurement. This category generally includes U.S. Government agency securities, state and municipal securities, mortgage-backed securities (“MBS”), commercial MBS, collateralized mortgage obligations, asset-backed securities, corporate bonds and trust preferred securities. Warrants . The Company measures the fair value of warrants based on unobservable inputs based on assumptions and management judgment, a Level 3 measurement. Foreign Exchange Contracts . The Company measures the fair value of foreign exchange contracts based on dealer quotes, a Level 2 measurement. Interest Rate Swaps . Fair value of interest rate swaps is derived from third party models with observable market data, a Level 2 measurement. Assets measured at estimated fair value on a non-recurring basis: Certain assets or liabilities are required to be measured at estimated fair value on a nonrecurring basis subsequent to initial recognition. Generally, these adjustments are the result of lower-of-cost-or-fair value or other impairment write-downs of individual assets. In determining the estimated fair values during the period, the Company determined that substantially all the changes in estimated fair value were due to declines in market conditions versus instrument specific credit risk. For the six months ended June 30, 2018 and December 31, 2017, there were no material adjustments to fair value for the Company’s assets and liabilities measured at fair value on a nonrecurring basis in accordance with GAAP. The following tables present the Company’s hierarchy for its assets and liabilities measured at fair value on a recurring basis as of June 30, 2018, and December 31, 2017:

The Company measured the fair value of its warrants on a recurring basis using significant unobservable inputs. The fair value of warrants was $176,000 as of June 30, 2018, compared to $91,000 as of December 31, 2017. The fair value adjustment of warrants was included in other operating income in the second quarter of 2018. The significant unobservable inputs in the Black-Scholes option pricing model for the fair value of warrants are their expected life ranging from 1 to 6 years, risk-free interest rate from 2.48% to 3.12%, and stock volatility from 8.19% to 12.80%. For financial assets measured at fair value on a nonrecurring basis that were still reflected in the condensed consolidated balance sheet as of June 30, 2018, the following tables provide the level of valuation assumptions used to determine each adjustment, the carrying value of the related individual assets as of June 30, 2018, and December 31, 2017, and the total gains and losses for the periods indicated:

The significant unobservable (Level 3 ) inputs used in the fair value measurement of collateral for collateral-dependent impaired loans was primarily based on the appraised value of collateral adjusted by estimated sales cost and commissions. The Company generally obtains new appraisal reports every twelve months. As the Company’s primary objective in the event of default would be to monetize the collateral to settle the outstanding balance of the loan, less marketable collateral would receive a larger discount. During the reported periods, collateral discounts ranged from 55% in the case of accounts receivable collateral to 65% in the case of inventory collateral. The significant unobservable inputs used in the fair value measurement of loans held for sale was primarily based on the quoted price or sale price adjusted by estimated sales cost and commissions. The significant unobservable inputs used in the fair value measurement of other real estate owned (“OREO”) was primarily based on the appraised value of OREO adjusted by estimated sales cost and commissions. The Company applies estimated sales cost and commissions ranging from 3% to 6% of the collateral value of impaired loans, quoted price, or loan sale price of loans held for sale, and appraised value of OREO.
