Fair Value Disclosures [Abstract]  
Fair Value Disclosures Fair Value Disclosures
We determine the fair market values of our assets and liabilities measured at fair value on a recurring and nonrecurring basis using the fair value hierarchy as prescribed in ASC 820. The standard describes three levels of inputs that may be used to measure fair value as provided below.

Level 1
Quoted prices in active markets for identical assets or liabilities.
Level 2
Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
Level 3
Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair values requires significant management judgment or estimation.
Assets and liabilities measured at fair value are as follows:

Tax-exempt asset-backed securities
The fair value of tax-exempt asset-backed securities is based on a discounted cash flow model, which utilizes Level 3, or unobservable, inputs, the most significant of which were a discount rate and weighted-average life. At December 31, 2019, a discount rate of 2.99% and a weighted-average life of 7.0 years were utilized to determine the fair value of these securities, compared to 4.21% and 9.2 years, respectively, at December 31, 2018.
CRT securities
The fair value of CRT securities is based on a discounted cash flow model, which utilizes Level 3, or unobservable, inputs, the most significant of which were a discount rate and weighted-average life. At December 31, 2019, a discount rate of 4.54% and a weighted-average life of 9.3 years were utilized to determine the fair value of these securities.
Loans held for sale
The fair value of loans held for sale using Level 3 inputs include loans that cannot be sold through normal sale channels and thus require significant management judgment or estimation when determining the fair value. The fair value of such loans is generally based upon quoted prices of comparable loans with a liquidity discount applied. At December 31, 2019, the fair value of these loans was calculated using a weighted-average discounted price of 94.1%, compared to 92.9% at December 31, 2018.
Loans held for investment
Certain impaired loans held for investment are reported at fair value through a specific valuation allowance allocation of the allowance for loan losses based upon the fair value of the underlying collateral. The $109.6 million fair value of loans held for investment at December 31, 2019 reported above includes impaired loans held for investment with a carrying value of $145.4 million that were reduced by specific valuation allowance allocations totaling $35.8 million based on collateral valuations utilizing Level 3 inputs. The $29.9 million fair value of loans held for investment at December 31, 2018 reported above includes impaired loans with a carrying value of $32.2 million that were reduced by specific valuation allowance allocations totaling $2.3 million based on collateral valuations utilizing Level 3 inputs.
OREO
Certain foreclosed assets, upon initial recognition, are recorded at fair value less estimated selling costs. At December 31, 2019 and 2018, OREO had a carrying value of $0 and $79,000, respectively, with no specific valuation allowance. The fair value of OREO was computed based on third party appraisals, which are Level 3 valuation inputs.
Fair Value of Financial Instruments
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. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. This disclosure does not and is not intended to represent the fair value of the Company.

The estimated fair value for cash and cash equivalents, variable rate loans and variable rate debt approximates carrying value. The following methods and assumptions were used by the Company in estimating its fair value disclosures for financial instruments:
Investment Securities
Within the investment securities portfolio, we hold equity securities related to our non-qualified deferred compensation plan that are valued using quoted market prices for identical equity securities in an active market, and are classified as Level 1 assets in the fair value hierarchy. The fair value of the remaining equity securities and residential mortgage-backed securities in our investment portfolio are based on prices obtained from independent pricing services that are based on quoted market prices for the same or similar securities, and are characterized as Level 2 assets in the fair value hierarchy. We have obtained documentation from our primary pricing service regarding their processes and controls applicable to pricing investment securities, and on a quarterly basis we independently verify the prices that we receive from the service provider using two additional independent pricing sources. We also hold tax-exempt asset-backed securities and CRT securities that are valued using a discounted cash flow model, which utilizes Level 3 inputs, and are classified as Level 3 assets in the fair value hierarchy.
Loans Held for Sale
Fair value for loans held for sale is derived from quoted market prices for similar loans, in which case they are characterized as Level 2 assets in the fair value hierarchy, or is derived from third party pricing models, in which case they are characterized as Level 3 assets in the fair value hierarchy.
Derivatives
The estimated fair value of interest rate swaps and caps is obtained from independent pricing services based on quoted market prices for similar derivative contracts and these financial instruments are characterized as Level 2 assets and liabilities in the fair value hierarchy. On a quarterly basis, we independently verify the fair value using an additional independent pricing source. Foreign currency forward contracts are valued based upon quoted market prices obtained from independent pricing services for similar derivative contracts. As such, these financial instruments are characterized as Level 2 assets and liabilities in the fair value hierarchy. The derivative instruments related to the loans held for sale portfolio include loan purchase commitments and forward sales commitments. Loan purchase commitments are valued based upon the fair value of the underlying mortgage loans to be purchased, which is based on observable market data for similar loans. Forward sales commitments are valued based upon quoted market prices from brokers. As such, these loan purchase commitments and forward sales commitments are characterized as Level 2 assets or liabilities in the fair value hierarchy.
