DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

ASC 820 applies to reported balances that are required or permitted to be measured at fair value under an existing accounting pronouncement. ASC 820 emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability and establishes a fair value hierarchy. The fair value hierarchy consists of three levels of inputs that may be used to measure fair value as follows:

Level 1 — Inputs that utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Level 1 assets and liabilities include debt and equity securities that are traded in an active exchange market, as well as certain U.S. Treasury securities that are highly liquid and are actively traded in over-the-counter markets.

Level 2 — Inputs other than those quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates and yield curves that are observable at commonly quoted intervals. Level 2 assets and liabilities include available-for-sale securities with quoted prices that are traded less frequently than exchange-traded instruments and derivative contracts whose value is determined using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. Available-for-sale securities are valued using observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, prepayment speeds, credit information, and the bond’s terms and conditions, among other things. Government guaranteed loans held-for-sale, which are guaranteed by the Small Business Administration ("SBA"), are valued based on observable market data and pricing. Derivative valuations utilize certain Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. The significance of the impact of these credit valuation adjustments on the overall valuation of derivative positions are not significant to the overall valuation and result in all derivative valuations being classified in Level 2 of the fair value hierarchy.

Level 3 — Inputs that are unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. This category includes loans where independent pricing information was not able to be obtained.

The tables below present the Company’s assets and liabilities measured at fair value on a recurring basis as of the dates set forth aggregated by the level in the fair value hierarchy within which those measurements fall.

Certain financial assets and financial liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). Assets measured on a nonrecurring basis include impaired loans, real estate acquired by foreclosure and other repossessed assets.

A loan is defined as impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due, according to the contractual terms of the loan agreement. The allowance for loan losses related to impaired loans is determined based on the difference between the carrying value of the impaired loan and its fair value. The fair value of impaired loans is determined based on the fair value of the collateral if repayment is expected solely from the collateral. Fair value of the loan’s collateral is determined by appraisals and third party estimates for real estate collateral and by appraisals or independent valuations for non-real estate collateral such as inventory, accounts receivable, equipment or other business assets. The fair value of real estate acquired by foreclosure is measured using appraisals and third party estimates. These values may be adjusted based on current information available to management, therefore the values are considered Level 3 inputs within the fair value hierarchy.

The following tables present the assets that were subject to fair value adjustments during the periods indicated, which were still on the balance sheet at the end of the reporting periods:

The following methods and assumptions were used to estimate the fair value of cash and other financial instruments, other than those described above:

Cash and Short-Term Investments — The carrying amount of these short term investments is a reasonable estimate of fair value.

Securities — The fair value of securities are obtained from an independent pricing service. Securities are valued based on quoted prices in an active market when available. These securities are classified in Level 1 of the valuation hierarchy. If quoted market prices are not available for the specific security, then fair values are estimated and classified as Level 2 of the valuation hierarchy. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury and other yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the security’s terms and conditions, among other things.

Loans Held for Sale — The fair value of government guaranteed loans held-for-sale is based on commitments from investors or prevailing market prices.

Loans Held for Investment — The calculation of fair value of loans reported for the 2018 reporting periods has been revised to be in accordance with ASU 2016-01. The discounted cash flow methodology considers internal and market-based information, including interest rates, prepayment speeds and discount rates. The fair value of loans as of December 31, 2017 was estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities.

Real Estate Acquired by Foreclosure — Real estate acquired by foreclosure is adjusted to fair value less estimated costs to sell at the time of foreclosure. Subsequently, these assets are carried at the lower of carrying value or fair value less estimated costs to sell. Fair value is generally based upon market prices or appraised values of the property, which may be discounted based on internal criteria and accordingly, the Company classifies real estate acquired by foreclosure as Level 3.

Deposit Liabilities — The fair value of demand deposits, savings accounts and certain money market deposits is the amount payable on demand at the reporting date. The fair value of certificates of deposit is estimated using the rates currently offered for deposits of similar remaining maturities in the peer market.

Other Borrowed Funds — The carrying amount of securities sold under agreements to repurchase is a reasonable estimate of fair value because these borrowings reprice at market rates generally daily. The fair value of long term FHLB advances is estimated using the rates currently offered for advances of similar remaining maturities.

Subordinated debentures and subordinated notes—The fair value of the subordinated debentures and subordinated notes was calculated using the quoted market prices, if available. If quoted market prices are not available, fair value is estimated using quoted market prices for similar subordinated debentures. Subordinated debentures and subordinated notes fair value measurements utilize Level 2 inputs.

Off-Balance Sheet Financial Instruments — The fair value of commitments is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For fixed-rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value of guarantees and letters of credit is based on fees currently charged for similar agreements or on the estimated cost to terminate them or otherwise settle the obligations with the counterparties at the reporting date. These amounts were not significant at the reporting dates. The fair value of interest rate swaps is derived from pricing models based on past, present and projected future market conditions, quoted market prices of instruments with similar characteristics or discounted cash flows, classified in Level 2 of the fair value hierarchy.

The estimated fair values of the Company’s financial instruments as of the dates indicated are as follows:
