Impact of COVID-19

On March 13, 2020, the United States President declared a national emergency in the face of a growing public health and economic crisis due to the COVID-19 global pandemic. Within a few days of the declaration of a national emergency, governors of states comprising the Company’s geographic footprint issued states of emergency in response to the novel COVID-19. As a result of this pandemic, actions were taken around the world to help mitigate the spread of COVID 19, which have impacted the economies and financial markets of many countries, including the geographical area in which the Company operates. On March 27, 2020, the CARES Act was signed into law. The CARES Act is designated to provide financial relief to the American people and American businesses in response to the economic fallout from COVID-19. On March 22, 2020, the five federal bank regulatory agencies and the Conference of State Bank Supervisors issued joint guidance (subsequently revised on April 7, 2020) with respect to loan modifications for borrowers affected by COVID-19. The CARES Act, as well as the March 22 Joint Guidance, provide enhanced guidelines and accounting for COVID-19 related modifications.

​

The federal banking regulators have confirmed with FASB that short-term loan modifications made on a good faith basis in response to COVID-19 to borrowers who were current (i.e., less than 30 days past due on contractual payments) prior to any loan modification are not TDRs. In addition, Section 4013 of the CARES Act provides banks, savings associations, and credit unions with the ability to make loan modifications related to COVID-19 without categorizing the loan as a TDR or conducting the analysis to make the determination, which is intended to streamline the loan modification process. Any such suspension is effective for the term of the loan modification; however, the suspension is only permitted for loan modifications made during the effective period of Section 4013 and only for those loans that were not more than thirty days past due as of December 31, 2019. The Company has made $1.8 billion of loan modifications pursuant to the March 22 Joint Guidance or Section 4013 of the CARES Act and as of June 30, 2020 approximately $1.6 billion remain under their modified terms.

​

During the second quarter of 2020, the Company continued to participate in the SBA PPP under the CARES Act. The Company processed over 11,000 loans, which totaled $1.7 billion with a recorded investment of $1.6 billion as of June 30, 2020, through the SBA PPP. The loans carry a 1% interest rate and the Company recorded net PPP loan origination fees of approximately $50.2 million, which are being amortized over a 24-month period.

Allowance for Loan and Lease Losses

The provision for loan losses charged to operations is an amount sufficient to bring the allowance to an estimated balance that management considers adequate to absorb expected losses in the Company’s loan portfolio. The ALLL is a valuation account that is deducted from the loans' amortized cost basis to present the net amount expected to be collected on the loans. Amortized cost is the principal balance outstanding, net of any purchase premiums and discounts and net of any deferred loan fees and costs.

The ALLL represents management’s estimate of credit losses over the remaining life of the loan portfolio. Loans are charged off against the ALLL when management believes the loan balance is no longer collectible. Subsequent recoveries of previously charged off amounts are recorded as increases to the ALLL.

Management’s determination of the adequacy of the ALLL is based on an evaluation of the composition of the loan portfolio, the value and adequacy of collateral, current economic conditions, historical loan loss experience,

reasonable and supportable forecasts, and other risk factors. The ALLL is estimated by pooling loans by call code and credit risk indicator and applying a loan-level PD/LGD method for all loans with the exception of its auto and third party consumer lending portfolios. For auto and third party consumer portfolios, the Company has elected to pool those loans based on similar risk characteristics to determine the ALLL using vintage and loss rate methods. The Company utilizes a forecast period of two years and then reverts to the mean of historical loss factors on a straight-line basis over the following two-year period. The Company considers economic forecasts and recession probabilities from highly recognized third-parties to inform the model for loss estimation. The Company’s ALLL estimate is particularly impacted by the unemployment rate forecast in its geographic footprint. In the current quarter forecast, the unemployment rate in the Company’s geographic footprint is projected to remain significantly elevated through the forecast period. Management also considers qualitative factors when estimating loan losses to take into account model limitations. For the current quarter, the largest qualitative additions were related to industries that are particularly impacted by the COVID pandemic, and were partially offset by qualitative reductions meant to account for enhanced unemployment benefits, bank deferrals, the PPP loan program and other factors. The Company’s Allowance Committee approves the key methodologies and assumptions, as well as the final ALLL on a quarterly basis. While management uses available information to estimate expected losses on loans, future changes in the ALLL may be necessary based on changes in portfolio composition, portfolio credit quality, and/or economic conditions.

Loans that do not share risk characteristics are evaluated on an individual basis. The individual reserve component relates to loans that have shown substantial credit deterioration as measured by risk rating and/or delinquency status. In addition, the Company has elected the practical expedient that would include loans for individual assessment consideration if the repayment of the loan is expected substantially through the operation or sale of collateral because the borrower is experiencing financial difficulty. Where the source of repayment is the sale of collateral, the ALLL is based on the fair value of the underlying collateral, less selling costs, compared to the amortized cost basis of the loan. If the ALLL is based on the operation of the collateral, the reserve is calculated based on the fair value of the collateral calculated as the present value of expected cash flows from the operation of the collateral, compared to the amortized cost basis. If the Company determines that the value of a collateral dependent loan is less than the recorded investment in the loan, the Company charges off the deficiency if it is determined that such amount is deemed to be a confirmed loss. Typically, a loss is confirmed when the Company is moving towards foreclosure (or final disposition).

In situations where, for economic or legal reasons related to a borrower’s financial condition, the Company grants a concession in the loan structure to the borrower that it would not otherwise consider, the related loan is classified as a TDR. With the exception of loans with interest rate concessions, the ALLL on a TDR is measured using the same method as all other loans held for investment. For loans with interest rate concessions, the Company uses a discounted cash flow approach using the original interest rate.

Acquired Loans

The Company has purchased loans, some of which have experienced more than insignificant credit deterioration since origination. Acquired loans are recorded at their fair value at acquisition date without carryover of the acquiree’s previously established ALLL, as credit discounts are included in the determination of fair value. The fair value of the loans is determined using market participant assumptions in estimating the amount and timing of both principal and interest cash flows expected to be collected on the loans and then applying a market-based discount rate to those cash flows. During evaluation upon acquisition, acquired loans are also classified as either PCD or acquired performing.

The purchase discount on acquired performing loans is accounted for under ASC 310-20, Receivables – Nonrefundable Fees and Other Costs. The difference between the fair value and unpaid principal balance of the loan at acquisition date (premium or discount) is amortized or accreted into interest income over the life of the loans. If the acquired performing loan has revolving privileges, it is accounted for using the straight-line method; otherwise, the effective interest method is used.

PCD loans reflect loans that have experienced more-than-insignificant credit deterioration since origination. These PCD loans are accounted for under ASC 326. Credit risk characteristics include risk rating groups, nonaccrual status, and past due status. For valuation purposes, these pools are further disaggregated by maturity, pricing characteristics, and re-payment structure.

PCD loans are recorded at the amount paid. An ALLL is determined using the same methodology as other loans held for investment. For PCD loans not individually assessed, the initial ALLL is determined on a collective basis and is allocated to individual loans. The sum of the loan's purchase price and ALLL becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the ALLL are recorded through provision expense.

The PCD loans are and will continue to be subject to the Company’s internal and external credit review and monitoring.

Investment Securities

Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are generally amortized on the level-yield method without anticipating prepayments, except for mortgage-backed securities where prepayments are anticipated. Premiums on callable debt securities are amortized to their earliest call date. Gains and losses on sales are recorded on the trade date and determined using the specific identification method.

The Company regularly evaluates all securities whose values have declined below amortized cost to assess whether the decline in fair value is the result of credit impairment. For AFS securities, the Company evaluates the fair value and credit quality of its AFS securities on at least a quarterly basis. In the event the fair value of a security falls below its amortized cost basis, the security will be evaluated to determine whether the decline in value was caused by changes in market interest rates or security credit quality. The primary indicators of credit quality for the Company’s AFS portfolio are security type and credit rating, which are influenced by a number of security-specific factors that may include obligor cash flow, geography, seniority, and others.

There is currently no ACL held against the Company’s AFS securities portfolio at June 30, 2020. See Note 3 “Securities,” for additional information on the Company’s ACL analysis. If unrealized losses are related to credit quality, the Company estimates the credit related loss by evaluating the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis of the security and a credit loss exists, an ACL shall be recorded for the credit loss, limited by the amount that the fair value is less than amortized cost basis. Non-credit related declines in fair value are recognized in other comprehensive income, net of applicable taxes. Changes in the ACL are recorded as provision for (or reversal of) credit loss expense. Charge-offs are recorded against the ACL when management believes the AFS security is no longer collectible. Currently, the Company does not have an ACL on its AFS debt securities portfolio. A debt security is placed on nonaccrual status at the time any principal or interest payments become 90 days delinquent.

The Company evaluates the credit risk of its HTM securities on at least a quarterly basis. Management estimates expected credit losses on held-to-maturity debt securities based on an individual basis based on the PD/LGD methodology primarily using security-level credit ratings. Management recorded an immaterial ACL on HTM securities as a result of the adoption of ASC 326, and no additional changes were needed at June 30, 2020.

Reserve for Unfunded Commitments

The Company estimates expected credit losses over the contractual period in which the Company is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. The reserve for unfunded commitments is adjusted as a provision for credit loss expense and is measured using the same measurement objectives as the ALLL. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded and is included in “Other Liabilities” within the Company’s Consolidated Balance Sheets.
