The following methods were used to estimate the fair value of each class of financial instrument that is carried at fair value in the tables above: 
 
Securities— Fair values for investment securities are based on quoted market prices when available or through the use of alternative approaches, such as matrix or model pricing, or broker indicative bids, when market quotes are not readily accessible or available. Management periodically reviews the pricing information received from the third-party pricing service and compares it to a secondary pricing service, evaluating significant price variances between services to determine an appropriate estimate of fair value to report.
 
Loans Held for Sale— Fair value for residential mortgage loans originated as held for sale is determined based on quoted secondary market prices for similar loans, including the implicit fair value of embedded servicing rights. For loans not originated as held for sale, these loans are accounted for at lower of cost or market, with the fair value estimated based on the expected sales price. As of December 31, 2020, there were $78.1 million in auto loans transferred to held for sale at the lower of cost or market.
 
Residential Mortgage Servicing Rights— The fair value of the MSRs is estimated using a discounted cash flow model. Assumptions used include market discount rates, anticipated prepayment speeds, delinquency and foreclosure rates, and ancillary fee income net of servicing costs. This model is periodically validated by an independent model validation group. The model assumptions and the MSR fair value estimates are also compared to observable trades of similar portfolios as well as to MSR broker valuations and industry surveys, as available. Management believes the significant inputs utilized are indicative of those that would be used by market participants.
Junior Subordinated Debentures— The fair value of junior subordinated debentures is estimated using an income approach valuation technique.  The significant inputs utilized in the estimation of fair value of these instruments are the credit risk adjusted spread and three-month LIBOR. The credit risk adjusted spread represents the nonperformance risk of the liability, contemplating the inherent risk of the obligation. The Company periodically utilizes a valuation firm to determine or validate the reasonableness of inputs and factors that are used to determine the fair value. The ending carrying (fair) value of the junior subordinated debentures measured at fair value represents the estimated amount that would be paid to transfer these liabilities in an orderly transaction amongst market participants.  Due to credit concerns in the capital markets and inactivity in the trust preferred markets that have limited the observability of market spreads, the Company has classified this as a Level 3 fair value measurement.  
 
Derivative Instruments— The fair value of the interest rate lock commitments and forward sales commitments are estimated using quoted or published market prices for similar instruments, adjusted for factors such as pull-through rate assumptions based on historical information, where appropriate.  The pull-through rate assumptions are considered Level 3 valuation inputs and are significant to the interest rate lock commitment valuation; as such, the interest rate lock commitment derivatives are classified as Level 3. The fair value of the interest rate swaps is determined using a discounted cash flow technique incorporating credit valuation adjustments to reflect nonperformance risk in the measurement of fair value. Although the Bank has determined that the majority of the inputs used to value its interest rate swap derivatives fall within Level 2 of the fair value hierarchy, the CVA associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of December 31, 2020, the Bank has assessed the significance of the impact of the CVA on the overall valuation of its interest rate swap positions and has determined that the CVA are not significant to the overall valuation of its interest rate swap derivatives. As a result, the Bank has classified its interest rate swap derivative valuations in Level 2 of the fair value hierarchy.   
 
Assets and Liabilities Measured at Fair Value Using Significant Unobservable Inputs (Level 3) 
 
The following table provides a description of the valuation technique, significant unobservable inputs, and qualitative information about the unobservable inputs for the Company's assets and liabilities classified as Level 3 and measured at fair value on a recurring basis at December 31, 2020:

Generally, increases in the constant prepayment rate or the discount rate utilized in the fair value measurement of the residential mortgage servicing rights will result in a decrease in fair value. Conversely, decreases in the constant prepayment rate or the discount rate will result in an increase in fair value.

An increase in the pull-through rate utilized in the fair value measurement of the interest rate lock commitment derivative will result in an increase in the fair value measurement. Conversely, a decrease in the pull-through rate will result in a decrease in the fair value measurement.
 
Management believes that the credit risk adjusted spread utilized in the fair value measurement of the junior subordinated debentures carried at fair value is indicative of the nonperformance risk premium a willing market participant would require under current market conditions, which is an inactive market. Future contractions in the instrument-specific credit risk adjusted spread relative to the spread currently utilized to measure the Company's junior subordinated debentures at fair value as of December 31, 2020, or the passage of time, will result in an increase in the estimated fair value. Generally, an increase in the credit spread will result in a decrease in the estimated fair value. Conversely, a decrease in the credit spread will result in an increase in the estimated fair value.

Change in unrealized gains or losses for the period included in other comprehensive income for assets held at end of period$— $— $(18,842)$— $— $(25,855)

Changes in residential mortgage servicing rights carried at fair value are recorded in residential mortgage banking revenue within non-interest income. Gains (losses) on interest rate lock commitments carried at fair value are recorded in residential mortgage banking revenue within non-interest income. The contractual interest expense on the junior subordinated debentures is recorded on an accrual basis as interest on junior subordinated debentures within interest expense. Settlements related to the junior subordinated debentures represent the payment of accrued interest that is embedded in the fair value of these liabilities.

The change in fair value of junior subordinated debentures is attributable to the change in the instrument specific credit risk; accordingly, the unrealized gains on fair value of junior subordinated debentures for the year ended December 31, 2020 of $18.8 million are recorded net of tax as other comprehensive income of $14.0 million. Comparatively, unrealized gains of $25.9 million were recorded net of tax as other comprehensive income of $19.2 million for the year ended December 31, 2019. The gain recorded for the year ended December 31, 2020 was due primarily to the implied forward curve shifting lower and an increase in the credit spread, offset by the spot curve shifting lower.

From time to time, certain assets are measured at fair value on a nonrecurring basis.  These adjustments to fair value generally result from the application of lower-of-cost-or-market accounting or write-downs of individual assets due to impairment, typically on collateral dependent loans.

Goodwill was evaluated for impairment as of March 31, 2020, for the Retail Bank and Wholesale Bank reporting units. Refer to Note 8 - Goodwill and Other Intangible Assets, for discussion of the Company's goodwill impairment analysis.

The following provides a description of the valuation technique and inputs for the Company's assets and liabilities classified as Level 3 and measured at fair value on a nonrecurring basis, excluding goodwill. Unobservable inputs and qualitative information about the unobservable inputs are not presented as the fair value is determined by third-party information for loans and leases and other real estate owned.

The loans and leases amounts above represent collateral dependent loans and leases that have been adjusted to fair value.  When a loan or non-homogeneous lease is identified as collateral dependent, the Bank measures the impairment using the current fair value of the collateral, less selling costs. Depending on the characteristics of a loan or lease, the fair value of collateral is generally estimated by obtaining external appraisals, but in some cases, the value of the collateral may be estimated as having little to no value. When a homogeneous lease or equipment finance agreement becomes 181 days past due, it is determined that the collateral has little to no value. If it is determined that the value of the collateral dependent loan or lease is less than its recorded investment, the Bank recognizes this impairment and adjusts the carrying value of the loan or lease to fair value, less costs to sell, through the allowance for credit losses.  The loss represents charge-offs on collateral dependent loans and leases for fair value adjustments based on the fair value of collateral. 
 
The other real estate owned amount above represents impaired real estate that has been adjusted to fair value.  Other real estate owned represents real estate which the Bank has taken control of in partial or full satisfaction of loans. At the time of foreclosure, other real estate owned is recorded at the lower of the carrying amount of the loan or fair value less costs to sell, which becomes the property's new basis. Any write-downs based on the asset's fair value at the date of acquisition are charged to the allowance for credit losses. After foreclosure, management periodically performs valuations such that the real estate is carried at the lower of its new cost basis or fair value, net of estimated costs to sell. Fair value adjustments on other real estate owned are recognized within other non-interest expenses. The loss represents impairments on other real estate owned for fair value adjustments based on the fair value of the real estate. 
 
Fair Value Option
The following table presents the difference between the aggregate fair value and the aggregate unpaid principal balance of loans held for sale accounted for under the fair value option as of December 31, 2020 and 2019:

Loans held for sale$688,079 $654,555 $33,524 $513,431 $496,683 $16,748 

Residential mortgage loans held for sale accounted for under the fair value option are measured initially at fair value with subsequent changes in fair value recognized in earnings. Gains and losses from such changes in fair value are reported as a component of residential mortgage banking revenue, net. For the years ended December 31, 2020, 2019 and 2018, the Company recorded a net increase in fair value of $16.8 million, a net increase of $10.6 million, and a net decrease of $2.6 million, respectively, representing the change in fair value reflected in earnings.

The Company selected the fair value measurement option for certain junior subordinated debentures. The remaining junior subordinated debentures were acquired through previous business combinations and were measured at fair value at the time of acquisition and subsequently measured at amortized cost.

Accounting for the selected junior subordinated debentures at fair value enables the Company to more closely align financial performance with the economic value of those liabilities. Additionally, it improves the ability to manage the market and interest rate risks associated with the junior subordinated debentures. The junior subordinated debentures measured at fair value and amortized cost are presented as separate line items on the balance sheet. The ending carrying (fair) value of the junior subordinated debentures measured at fair value represents the estimated amount that would be paid to transfer these liabilities in an orderly transaction amongst market participants under current market conditions as of the measurement date.
Due to inactivity in the junior subordinated debenture market and the lack of observable quotes of the Company's, or similar, junior subordinated debenture liabilities or the related trust preferred securities when traded as assets, the Company utilizes an income approach valuation technique to determine the fair value of these liabilities using estimation of market discount rate assumptions. The Company monitors activity in the trust preferred and related markets, to the extent available, evaluates changes related to the current and anticipated future interest rate environment, and considers entity-specific creditworthiness, to validate the reasonableness of the credit risk adjusted spread and effective yield utilized in the discounted cash flow model. The Company also considers changes in the interest rate environment in the valuation, specifically the absolute level and the shape of the slope of the forward swap curve.
