Significant Accounting Policies

Significant Accounting Policies

Our accounting policies are described in Note 1. Nature of Operations and Summary of Significant Accounting Policies, of our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2019 as filed with the Securities and Exchange Commission ("Form 10-K"). Updates to our significant accounting policies described below reflect the impact of the adoption of ASU 2016-13, “Financial Instruments - Credit Losses (ASC 326): Measurement of Credit Losses on Financial Instruments” and the related amendments, commonly referred to as CECL.

Investment Securities

Prior to January 1, 2020, debt securities available-for-sale were measured at fair value and declines in the fair value were reviewed to determine whether the impairment was other-than-temporary. If the decline in fair value was considered temporary, the decline in fair value below the amortized cost basis of a security was recognized in other comprehensive income (loss). If we did not expect to recover the entire amortized cost basis of the security, then an other-than-temporary impairment was considered to have occurred. The cost basis of the security was written down to its estimated fair value and the amount of the write-down was recognized through a charge to earnings. If the amount of the amortized cost basis expected to be recovered increased in a future period, the cost basis of the security was not increased but rather recognized prospectively through interest income.

Effective January 1, 2020, upon the adoption of ASU 2016-13, debt securities available-for-sale are measured at fair value and are subject to impairment testing. A security is impaired if the fair value of the security is less than its amortized cost basis. When an available-for-sale debt security is considered impaired, the Company must determine if the decline in fair value has resulted from a credit-related loss or other factors and then, (1) recognize an allowance for credit losses by a charge to earnings for the credit-related component (if any) of the decline in fair value, and (2) recognize in other comprehensive income (loss) any non-credit related components of the fair value decline (if any). If the amount of the amortized cost basis expected to be recovered increases in a future period, the valuation allowance would be reduced, but not more than the amount of the current existing allowance for that security.

Purchased Loans with Credit Deterioration

Prior to January 1, 2020, purchased credit impaired loans were accounted for in accordance with ASC Subtopic 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality.” At the time of acquisition, these loans were recorded at estimated fair value based upon estimated future cash flows with no related allowance for credit losses.

Effective January 1, 2020, upon the adoption of ASU 2016-13, an entity records purchased financial assets with credit deterioration ("PCD assets") at the purchase price plus the allowance for credit losses expected at the time of acquisition. This allowance is recognized through a gross-up that increases the amortized cost basis of the asset with no effect on net income. Subsequent changes (favorable and unfavorable) in expected cash flows are recognized immediately in net income by adjusting the related allowance.

Allowance for Credit Losses on Loans and Leases Held for Investment

Effective January 1, 2020, upon the adoption of ASU 2016-13, the Company replaced the incurred loss accounting approach with the current expected credit loss ("CECL") approach for financial instruments measured at amortized cost and other commitments to extend credit. CECL requires the immediate recognition of estimated credit losses expected to occur over the estimated remaining life of the asset. The forward-looking concept of CECL requires loss estimates to consider historical experience, current conditions and reasonable and supportable forecasts.

The allowance for credit losses on loans and leases held for investment is the combination of the allowance for loan and lease losses and the reserve for unfunded loan commitments. The allowance for loan and lease losses is reported as a reduction of the amortized cost basis of loans and leases, while the reserve for unfunded loan commitments is included within "Accrued interest payable and other liabilities" on the condensed consolidated balance sheets. The amortized cost basis of loans and leases does not include accrued interest receivable, which is included in "Other assets" on the condensed consolidated balance sheets. The "Provision for credit losses" on the condensed consolidated statements of earnings (loss) is a combination of the provision for loan and lease losses and the provision for unfunded loan commitments.

Under the CECL methodology, expected credit losses reflect losses over the remaining contractual life of an asset, considering the effect of prepayments and available information about the collectability of cash flows, including information about relevant historical experience, current conditions, and reasonable and supportable forecasts of future events and circumstances. Thus, the CECL methodology incorporates a broad range of information in developing credit loss estimates. The resulting allowance for loan and lease losses is deducted from the associated amortized cost basis to reflect the net amount expected to be collected. Subsequent changes in this estimate are recorded through the provision for credit losses and the allowance. The CECL methodology could result in significant changes to both the timing and amounts of provision for credit losses and the allowance as compared to historical periods. Loans and leases that are deemed to be uncollectable are charged off and deducted from the allowance. The provision for credit losses and recoveries on loans and leases previously charged off are added to the allowance.

The allowance for loan and lease losses is comprised of an individually evaluated component for loans and leases that no longer share similar risk characteristics with other loans and leases and a pooled loans component for loans and leases that share similar risk characteristics.

A loan or lease with an outstanding balance greater than $250,000 is individually evaluated for expected credit loss when it is probable that we will be unable to collect all amounts due according to the original contractual terms of the agreement. We select loans and leases for individual assessment on an ongoing basis using certain criteria such as payment performance, borrower reported and forecasted financial results, and other external factors when appropriate. We measure the current expected credit loss of an individually evaluated loan or lease based upon the fair value of the underlying collateral if the loan or lease is collateral-dependent or the present value of cash flows, discounted at the effective interest rate, if the loan or lease is not collateral-dependent. To the extent a loan or lease balance exceeds the estimated collectable value, a reserve or charge-off is recorded depending upon either the certainty of the estimate of loss or the fair value of the loan’s collateral if the loan is collateral-dependent.

Our CECL methodology for the pooled loans component includes both quantitative and qualitative loss factors which are applied to our population of loans and leases and assessed at a pool level. The quantitative CECL model estimates credit losses by applying pool-specific probability of default ("PD") and loss given default ("LGD") rates to the expected exposure at default ("EAD") over the contractual life of loans and leases. The qualitative component considers internal and external risk factors that may not be adequately assessed in the quantitative model.

The loan portfolio is segmented into four loan segments, eight loan classes, and 19 loan pools (excluding Paycheck Protection Program loans, which are fully government guaranteed) based upon loan type that share similar default risk characteristics to calculate quantitative loss factors for each pool. Three of these loan pools have insignificant current balances and/or insignificant historical losses, thus, estimated losses are calculated using historical loss rates from the first quarter of 2009 to the current period rather than econometric regression modeling. For the remaining 16 loan pools, we estimate the PD during the reasonable and supportable forecast period using seven econometric regression models developed to correlate macroeconomic variables to historical credit performance (based on quarterly transition matrices from 2009 to 2019, which include risk rating upgrades/downgrades and defaults). The loans and unfunded commitments are grouped into nine LGD pools based on portfolio classes that share similar collateral risk characteristics. LGD rates are computed based on the net charge-offs recognized divided by the EAD of defaulted loans starting with the first quarter of 2009 to the current period. The PD and LGD rates are applied to the EAD at the loan or lease level based on contractual scheduled payments and estimated prepayments. We use our actual historical loan prepayment experience from 2009 to 2019 to estimate future prepayments by loan pool.

For the reasonable and supportable forecast period, future macroeconomic events and circumstances are estimated over a 4-quarter time horizon using a single scenario baseline forecast that is consistent with management's current expectations for the 16 loan pools. We use economic forecasts from Moody's Analytics in this process. The economic forecast is updated monthly; therefore, the one used for each quarter-end calculation is generally based on a one-month lag based on the timing of when the forecast is released. If economic conditions as of the balance sheet date change materially, management would consider a qualitative adjustment. The key macroeconomic assumptions used in each of the seven PD regression models include two or three of the following economic indicators: Real GDP, unemployment rates, CRE Price Index, the BBB corporate spread, nominal disposable income, and CPI. The quantitative CECL model applies the projected rates based on the economic forecasts for the 4-quarter reasonable and supportable forecast horizon to EAD to estimate defaulted loans. During this forecast horizon, prepayment rates during a historical period that exhibits economic conditions most similar to the economic forecast are used to estimate EAD. If no historical period from 2009 to 2019 exhibits economic conditions that are similar to the economic forecast, management considers the average of all historical prepayment experience to be a reasonable and supportable estimation of expected prepayments. Historical LGD rates are applied to estimated defaulted loans to determine estimated credit losses. We then use a 2-quarter reversion period to revert on a straight-line basis from the PD, LGD, and prepayment rates used during the reasonable and supportable forecast period to the Company’s historical PD, LGD, and prepayment experience. Subsequent to the reversion period for the remaining contractual life of loans and leases, the PD, LGD, and prepayment rates are based on historical experience from 2009 to 2019. PD regression models and prepayment rates are updated on an annual basis. LGD rates are updated every quarter to reflect current charge-off activity.

The PDs calculated by the quantitative models are highly correlated to our internal risk ratings assigned to each loan and lease. To ensure the accuracy of our credit risk ratings, an independent credit review function assesses the appropriateness of the credit risk ratings assigned to loans and leases on a regular basis. The credit risk ratings assigned to every loan and lease are as follows:

•High Pass: (Risk ratings 1-2) Loans and leases rated as "high pass" exhibit a favorable credit profile and have minimal risk characteristics. Repayment in full is expected, even in adverse economic conditions.

•Pass: (Risk ratings 3-4) Loans and leases rated as "pass" are not adversely classified and collection and repayment in full are expected.

•Special Mention: (Risk rating 5) Loans and leases rated as "special mention" have a potential weakness that requires management's attention. If not addressed, these potential weaknesses may result in further deterioration in the borrower's ability to repay the loan or lease.

•Substandard: (Risk rating 6) Loans and leases rated as "substandard" have a well-defined weakness or weaknesses that jeopardize the collection of the debt. They are characterized by the possibility that we will sustain some loss if the weaknesses are not corrected.

•Doubtful: (Risk rating 7) Loans and leases rated as "doubtful" have all the weaknesses of those rated as "substandard," with the additional trait that the weaknesses make collection or repayment in full highly questionable and improbable.

We may refer to the loans and leases with assigned credit risk ratings of "substandard" and "doubtful" together as "classified" loans and leases. For further information on classified loans and leases, see Note 4. Loans and Leases of the Notes to Condensed Consolidated Financial Statements (Unaudited) contained in "Item 1. Condensed Consolidated Financial Statements (Unaudited)."

In addition to our internal risk rating process, our federal and state banking regulators, as an integral part of their examination process, periodically review the Company’s loan and lease risk rating classifications. Our regulators may require the Company to recognize rating downgrades based on their judgments related to information available to them at the time of their examinations. Risk rating downgrades generally result in increases in the provisions for credit losses and the allowance for credit losses.

The qualitative portion of the reserve on pooled loans and leases represents management’s judgment of additional considerations to account for internal and external risk factors that are not adequately measured in the quantitative reserve. The qualitative loss factors consider idiosyncratic risk factors, conditions that may not be reflected in quantitatively derived results, or other relevant factors to ensure the allowance for credit losses reflects our best estimate of current expected credit losses. Current and forecasted economic trends and underlying market values for collateral dependent loans are generally considered to be encompassed within the CECL quantitative reserve. An incremental qualitative adjustment may be considered when economic forecasts exhibit higher levels of volatility or uncertainty.

In addition to economic conditions and collateral dependency, the other qualitative criteria we consider when establishing the loss factors include the following:

•Legal and Regulatory - matters that could impact our borrowers’ ability to repay our loans and leases;

•Concentrations - loan and lease portfolio composition and any loan concentrations;

•Lending Policy - current lending policies and the effects of any new policies or policy amendments;

•Nature and Volume - loan and lease production volume and mix;

•Problem Loan Trends - loan and lease portfolio credit performance trends, including a borrower's financial condition, credit rating, and ability to meet loan payment requirements;

•Loan Review - results of independent credit review; and

•Management - changes in management related to credit administration functions.

We estimate the reserve for unfunded loan commitments using the same PD, LGD, and prepayment rates for the quantitative credit losses and qualitative loss factors as used for the allowance for loan and lease losses. The EAD for the reserve for unfunded loan commitments is computed using expected future utilization rates of the unfunded commitments during the contractual life of the commitments based on historical usage by loan pool from 2015 to 2019. The utilization rates are updated on an annual basis.

The CECL methodology requires a significant amount of management judgment in determining the appropriate allowance for credit losses. Most of the steps in the methodology involve judgment and are subjective in nature including, among other things: segmenting the loan and lease portfolio; determining the amount of loss history to consider; selecting predictive econometric regression models that use appropriate macroeconomic variables; determining the methodology to forecast prepayments; selecting the most appropriate economic forecast scenario; determining the length of the reasonable and supportable forecast and reversion periods; estimating expected utilization rates on unfunded loan commitments; and assessing relevant and appropriate qualitative factors. In addition, the CECL methodology is dependent on economic forecasts which are inherently imprecise and will change from period to period. Although the allowance for credit losses is considered appropriate, there can be no assurance that it will be sufficient to absorb future losses.

Management believes the allowance for credit losses is appropriate for the current expected credit losses in our loan and lease portfolio and associated unfunded commitments, and the credit risk ratings and inherent loss rates currently assigned are reasonable and appropriate as of the reporting date. It is possible that others, given the same information, may at any point in time reach different conclusions that could result in a significant impact to the Company's financial statements.

Recently Issued Accounting Standards

Accounting Standards Adopted in 2020

Effective January 1, 2020, the Company adopted ASU 2016-13 and the related amendments to ASC Topic 326, “Financial Instruments - Credit Losses,” to replace the incurred loss accounting approach with a current expected credit loss approach for financial instruments measured at amortized cost and other commitments to extend credit. The new standard is generally intended to require earlier recognition of credit losses. While the standard changes the measurement of the allowance for credit losses, it does not change the credit risk of our lending portfolios or the ultimate losses in those portfolios.

Under the CECL approach, the standard requires immediate recognition of estimated credit losses expected to occur over the estimated remaining life of the asset. The forward-looking concept of CECL requires loss estimates to consider historical experience, current conditions and reasonable and supportable forecasts. The standard modifies the other-than-temporary impairment model for available-for-sale debt securities to require entities to record an allowance when recognizing credit losses for available-for-sale securities, rather than reducing the amortized cost of the securities by direct write-offs.

The Company adopted the new standard using the modified retrospective approach and recognized a cumulative effect adjustment to decrease retained earnings by $5.3 million, net of taxes, and increase the allowance for credit losses by $7.3 million without restating prior periods and applied the requirements of the new standard prospectively. There was no cumulative effect adjustment related to available-for-sale securities at adoption. The Company elected to account for interest receivable separately from the amortized cost of loans and leases and investment securities. Interest receivable is included in "Other assets" on the condensed consolidated balance sheets. The Company elected the practical expedient to use the fair value of the collateral at the reporting date when recording the net carrying amount of the asset and determining the allowance for credit losses for a financial asset for which the repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty based on the entity’s assessment as of the reporting date (collateral dependent financial asset). Additionally, the Company implemented new business processes, new internal controls, and modified existing and/or implemented new internal models and tools to facilitate the ongoing application of the new standard. See Note 4. Loans and Leases for further details.

Effective January 1, 2020, the Company adopted ASU 2017-04, "Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment" which simplifies goodwill impairment testing by eliminating the second step of the analysis under which the implied fair value of goodwill is determined as if the reporting unit were being acquired in a business combination. The goodwill impairment test is performed by comparing the fair value of a reporting unit with its carrying amount, and an impairment charge would be recognized for any amount by which the carrying amount exceeds the reporting unit's fair value, to the extent that the loss recognized does not exceed the amount of goodwill allocated to that reporting unit.

The Company used this approach to evaluate its goodwill during the first quarter of 2020, as an unprecedented decline in economic conditions triggered by the Coronavirus Disease ("COVID-19") pandemic caused a significant decline in stock market valuations in March 2020, including our stock price. These events indicated that goodwill may be impaired and resulted in us performing a goodwill impairment assessment. We applied the market approach using an average share price of the Company's stock and a control premium to determine the fair value of the reporting unit. As a result, a goodwill impairment charge of $1.47 billion was recorded in the first quarter of 2020 as the Company's estimated fair value was less than its book value.

Effective January 1, 2020, the Company adopted the provisions of ASU 2018-13, "Fair Value Measurement (Topic 820): Disclosure Framework - Changes to Disclosure Requirements for Fair Value Measurements" which add disclosures regarding changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty. Although the guidance modifies our disclosures in 2020, there was no impact to our condensed consolidated financial statements from the adoption of this new standard.

ASU 2020-03, "Codification Improvements to Financial Instruments" ("ASU 2020-03"), revised a wide variety of topics in the Codification with the intent to make the Codification easier to understand and apply by eliminating inconsistencies and providing clarifications. ASU 2020-03 was effective immediately upon its release in March 2020 and did not have a material impact to our condensed consolidated financial statements.

Basis of Presentation

Basis of Presentation    Our interim condensed consolidated financial statements are prepared in accordance with U.S. GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934. Accordingly, certain disclosures accompanying annual consolidated financial statements are omitted. In the opinion of management, all significant intercompany accounts and transactions have been eliminated and adjustments, consisting solely of normal recurring accruals and considered necessary for the fair presentation of financial statements for the interim periods, have been included. The current period's results of operations are not necessarily indicative of the results that ultimately may be achieved for the year. The interim condensed consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Form 10-K.

Use of Estimates

Use of EstimatesWe have made a number of estimates and assumptions related to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period to prepare these condensed consolidated financial statements in conformity with U.S. GAAP. Actual results could differ from those estimates. Material estimates subject to change in the near term include, among other items, the allowance for credit losses, the carrying value of goodwill and other intangible assets, and the realization of deferred tax assets. These estimates may be adjusted as more current information becomes available, and any adjustment may be significant.
