Fair Value Disclosures [Abstract] |
Fair Value Accounting and Measurement | Fair Value Accounting and Measurement The Fair Value Measurements and Disclosures topic of the FASB ASC defines fair value, establishes a consistent framework for measuring fair value and expands disclosure requirements about fair value. We hold fixed and variable rate interest-bearing securities, investments in marketable equity securities and certain other financial instruments, which are carried at fair value. Fair value is determined based upon quoted prices when available or through the use of alternative approaches, such as matrix or model pricing, when market quotes are not readily accessible or available. The valuation techniques are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our own market assumptions. These two types of inputs create the following fair value hierarchy: Level 1 – Quoted prices for identical instruments in active markets that are accessible at the measurement date. Level 2 – Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model derived valuations whose inputs are observable or whose significant value drivers are observable. Level 3 – Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable. Fair values are determined as follows: Securities at fair value are priced using a combination of market activity, industry recognized information sources, yield curves, discounted cash flow models and other factors. These fair value calculations are considered a Level 2 input method under the provisions of the Fair Value Measurements and Disclosures topic of the FASB ASC for all securities other than U.S. Treasury Notes and other securities, which are considered a Level 1 input method. Interest rate contract positions are valued in models, which use as their basis, readily observable market parameters and are classified within Level 2 of the valuation hierarchy. The following table sets forth the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis at December 31, 2018 and 2017 by level within the fair value hierarchy. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement:

There were no transfers between Level 1 and Level 2 of the valuation hierarchy during the year ended December 31, 2018. During the year ended December 31, 2017, there was a transfer of $5.1 million out of Level 2 of the valuation hierarchy and a corresponding transfer into Level 1 of the valuation hierarchy related to the Company’s equity securities. The Company recognizes transfers between levels of the valuation hierarchy based on the valuation level at the end of the reporting period. Nonrecurring Measurements Certain assets and liabilities are measured at fair value on a nonrecurring basis after initial recognition such as loans measured for impairment and OREO. The following methods were used to estimate the fair value of each such class of financial instrument: Impaired loans—A loan is considered to be impaired when, based on current information and events, it is probable that the Company will be unable to collect all amounts due (both interest and principal) according to the contractual terms of the loan agreement. Impaired loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, a loan’s observable market price, or the fair market value of the collateral less estimated costs to sell if the loan is a collateral-dependent loan. The impairment evaluations are performed in conjunction with the ALLL process on a quarterly basis by officers in the Special Credits group, which reports to the Chief Credit Officer. The Real Estate Appraisal Services Department (“REASD”), which also reports to the Chief Credit Officer, is responsible for obtaining appraisals from third-parties or performing internal evaluations. If an appraisal is obtained from a third-party, the REASD reviews the appraisal to evaluate the adequacy of the appraisal report, including its scope, methods, accuracy, and reasonableness. Other real estate owned —OREO is real property that the Bank has taken ownership of in partial or full satisfaction of a loan or loans. OREO is generally measured based on the property’s fair market value as indicated by an appraisal or a letter of intent to purchase. OREO is initially recorded at the fair value less estimated costs to sell. This amount becomes the property’s new basis. Any fair value adjustments based on the property’s fair value less estimated costs to sell at the date of acquisition are charged to the ALLL, or in the event of a write-up without previous losses charged to the ALLL, a credit to earnings is recorded. Management periodically reviews OREO in an effort to ensure the property is recorded at its fair value, net of estimated costs to sell. Any fair value adjustments subsequent to acquisition are charged or credited to earnings. The initial and subsequent evaluations are performed by officers in the Special Credits group, which reports to the Chief Credit Officer. The REASD obtains appraisals from third-parties for OREO and performs internal evaluations. If an appraisal is obtained from a third-party, the REASD reviews the appraisal to evaluate the adequacy of the appraisal report, including its scope, methods, accuracy, and reasonableness. The following table sets forth the Company’s assets that were measured using fair value estimates on a nonrecurring basis during the years ended December 31, 2018 and 2017:

The losses on impaired loans disclosed above represent the amount of the specific reserve and/or charge-offs during the period applicable to loans held at period end. The amount of the specific reserve is included in the “Allowance for loan and lease losses.” The losses on OREO disclosed above represent the write-downs taken at foreclosure that were charged to the allowance for loan and lease losses, as well as subsequent changes in any valuation allowances from updated appraisals that were recorded to earnings. Quantitative information about Level 3 fair value measurements The range and weighted average of the significant unobservable inputs used to fair value our Level 3 nonrecurring assets during 2018 and 2017, along with the valuation techniques used, are shown in the following tables:
|  | Fair value at December 31, 2018 |  | Valuation Technique |  | Unobservable Input |  | Range (Weighted Average) (1)

Impaired loans - collateral-dependent (2) |  | $ | 8,394 |  |  | Fair Market Value of Collateral |  | Adjustment to Stated Value |  | 0.00% - 70.04% (7.02%) |
Impaired loans - other (3) |  | $ | 3,161 |  |  | Discounted Cash Flow |  | Discount Rate |  | 0.34 | %
__________ (1) Discount rate applied to discounted cash flow valuation or appraisal value and stated value (in the case of fixed assets and inventory). (2) Collateral consists of accounts receivable, inventory, fixed assets, real estate and cash. (3) As there was only one impaired loan remeasured using discounted cash flows, a range of discounts could not be provided.

__________ (1) Discount rate used in discounted cash flow valuation. (2) Quantitative disclosures are not provided for collateral-dependent impaired loans and OREO because there were no adjustments made to the appraisal values or stated values during the current period.
