Through Corporate Billing, the Company also purchases receivables predominantly from transportation companies and automotive parts and service providers nationwide and occasionally purchases receivables from manufacturing and other types of companies. Although the Company has a diversified loan portfolio, a substantial portion of the loan portfolio is collateralized by improved and unimproved real estate and is dependent upon prevailing conditions in the real estate market. Portfolio segments utilized by the Company are identified below. Relevant risk characteristics for these portfolio segments generally include (i) debt service coverage, loan-to-value ratios, and financial performance, for non-consumer loans, and (ii) credit scores, debt-to-income ratios, collateral type and loan-to-value ratios, for consumer loans. The following table presents the balance in the allowance for loan losses and the recorded investment in loans by portfolio segment and based on impairment method for the periods indicated.

Fair Value Disclosures [Text Block]	Note 6 – Fair Value Measurements and Disclosures 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, derivative financial instruments and mortgage loans held-for-sale are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may Fair Value Hierarchy The Company groups assets and liabilities at fair value in three Level 1 Level 2 not Level 3 one not The following is a description of valuation methodologies used for assets and liabilities recorded or disclosed at fair value. Cash and Cash Equivalents For disclosure purposes, the carrying amount for cash, due from banks, interest-bearing deposits and federal funds sold is a reasonable estimate of fair value. Investment Securities Securities available-for-sale are recorded at fair value on a recurring basis. Fair value measurements are based on quoted prices, if available. If quoted prices are not 1 2 3 The fair value of securities held-to-maturity is estimated using the same measurement techniques as securities available-for-sale. Other Investments For disclosure purposes, the carrying amount of other investments approximates their fair value. Loans The Company does not not one three not June 30, 2017 December 31, 2016, 2. 3. For disclosure purposes, the fair value of fixed-rate loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings. For variable-rate loans, the carrying amount is a reasonable estimate of fair value. Mortgage Loans Held-for-Sale Mortgage loans held-for-sale are carried at fair value. The fair value of committed mortgage loans held-for-sale is determined by outstanding commitments from investors, and the fair value of uncommitted loans is based on the current delivery prices in the secondary mortgage market. Bank-Owned Life Insurance For disclosure purposes, the fair value of the cash surrender value of life insurance policies is equivalent to the carrying value. Other Real Estate Other real estate properties are adjusted to fair value upon the transfer of the loans to other real estate. Subsequently, other real estate assets are carried at the lower of carrying value or fair value. Fair value is based on independent market prices, appraised values of the collateral, or management’s estimation of the value of the collateral. When the fair value of the collateral is based on an observable market price, the Company records the other real estate as nonrecurring Level 2. 3. Deposits For disclosure purposes, the fair value of demand deposits, NOW and money market accounts and savings accounts is the amount payable on demand at the reporting date. The fair value of fixed-rate maturity certificates of deposit is estimated by discounting the future cash flows using the rates currently offered for deposits of similar remaining maturities. Federal Home Loan Bank Advances For disclosure purposes, the fair value of Federal Home Loan Bank (“FHLB”) advances is based on the quoted value for similar remaining maturities provided by the FHLB. Subordinated Debt For disclosure purposes, the fair value of our fixed-rate subordinated debt is estimated using a discounted cash flow model that utilizes current market interest rates on borrowings with a similar maturity. Derivative Financial Instruments Derivative financial instruments are recorded at fair value on a recurring basis. The value of the Company’s derivative financial instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis, on the expected cash flows of the derivative. This analysis reflects the contractual terms of the derivative, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The fair values of the interest rate swaps are determined by using the market standard methodology of netting the discounted future fixed cash receipts and the discounted expected variable cash payments. The variable cash payments are based on an expectation of future interest rates (forward curves derived from observable market interest rate curves). The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company considers the impact of netting any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. Although the Company has determined that a majority of the inputs used to value its derivatives falls within Level 2 3 June 30, 2017 December 31, 2016, not 2 Commitments to Extend Credit and Standby Letters of Credit Because commitments to extend credit and standby letters of credit are generally short-term and made using variable rates, the carrying value and estimated fair value associated with these instruments are immaterial.
