Standards Adopted in 2020
ASU 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and subsequent related ASUs	January 1, 2020 Early adoption is permitted on January 1, 2019.	The ASU introduces a new current expected credit losses (“CECL”) model that applies to most financial assets measured at amortized cost and certain instruments, including trade and other receivables, loan receivables, AFS and held-to-maturity debt securities, net investments in leases and off-balance sheet credit exposures. The CECL model utilizes a lifetime “expected credit loss” measurement objective for the recognition of credit losses at the time the financial asset is originated or acquired. The expected credit losses are adjusted in each period for changes in expected lifetime credit losses. ASU 2016-13 also eliminates the guidance for purchased credit impaired (“PCI”) loans, but requires an allowance for loan losses for purchased financial assets with more than an insignificant deterioration of credit since origination. The ASU also modifies the other-than-temporary impairment (“OTTI”) model for AFS debt securities to require an allowance for credit losses instead of a direct write-down. A reversal of the allowance for credit losses is allowed in future periods based on improvements in credit performance expectations. This ASU expands the disclosure requirements regarding an entity’s assumptions, models and methods for estimating the allowance for loan and lease losses, and requires disclosure of the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination (i.e., by vintage year). The guidance should be applied using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the reporting period of adoption. The new guidance also allows optional relief for certain instruments measured at amortized cost with an option to irrevocably elect the fair value option under ASC Topic 825, Financial Instruments.	The Company adopted ASU 2016-13 using a modified retrospective approach on January 1, 2020 without electing the fair value option on eligible financial instruments under ASU 2019-05. The adoption of this ASU increased the allowance for loan losses by $125.2 million, and allowance for unfunded credit commitments by $10.5 million and an after-tax decrease to opening retained earnings of $98.0 million on January 1, 2020. The increase to allowance for loan losses was primarily related to the commercial and industrial (“C&I”) and commercial real estate (“CRE”) loan portfolios. The Company did not record an allowance for credit losses related to the Company’s AFS debt securities as a result of this adoption. Disclosures for periods after January 1, 2020 are presented in accordance with ASC 326 while prior period amounts continue to be reported in accordance with previously applicable standards and the accounting policies described in the Company’s 2019 Form 10-K. The Company has elected the CECL phase-in option provided by regulatory capital rules, which delays the impact of CECL on regulatory capital for two years, followed by a three-year transition period.
ASU 2017-04, Intangibles — Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment	January 1, 2020 Early adoption is permitted for interim or annual goodwill impairment tests with measurement dates after January 1, 2017.	The ASU simplifies the accounting for goodwill impairment. Under this guidance, an entity will no longer perform a hypothetical purchase price allocation to measure goodwill impairment. Instead, an impairment loss will be recognized when the carrying amount of a reporting unit exceeds its fair value and the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The guidance also eliminates the requirement to perform a qualitative assessment for any reporting units with a zero or negative carrying amount. This guidance should be applied prospectively.	The Company adopted this guidance on January 1, 2020. The adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements.
ASU 2018-15, Intangibles — Goodwill and Other — Internal-Use Software (Subtopic 350-40) Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract	January 1, 2020	The ASU amends ASC Topic 350-40 to align the accounting for costs incurred in a cloud computing arrangement with the guidance on developing internal use software. Specifically, if a cloud computing arrangement is deemed to be a service contract, certain implementation costs are eligible for capitalization. The new guidance prescribes the balance sheet and income statement presentation and cash flow classification for the capitalized costs and related amortization expense. The amendments in this ASU should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption.	The Company adopted this guidance on a prospective basis on January 1, 2020. The adoption of this guidance did not have a material impact on the Company’s Consolidated Financial Statements.

Standard Not Yet Adopted
ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting	Effective for all entities as of March 12, 2020 through December 31, 2022.	In March 2020, the FASB issued a new accounting standard related to contracts or hedging relationships that reference London interbank offered rate or other reference rates that are expected to be discontinued due to reference rate reform. This ASU provides temporary optional expedients and exceptions regarding the accounting requirements related to the modification of certain contracts, hedging relationships and other transactions that are affected by the reference rate reform. The guidance permits the Company to make a one-time election to sell and/or transfer qualifying held-to-maturity securities, and not to apply modification accounting or remeasure lease payments in lease contracts if the changes to the contract are related to the discontinuation of the reference rate. If certain criteria are met, the amendments also allow exceptions to the de-designation criteria of the hedging relationship and the assessment of hedge effectiveness during the transition period. This one time election may be made at any time after March 12, 2020, but no later than December 31, 2022.	The Company has not yet made a determination on whether it will make this election and is currently tracking the exposure as of each reporting period and assessing the significance of impact towards implementing any necessary modification in consideration of the election of this amendment. The Company will continue to assess the impact as the reference rate transition occurs over the next two years.

Summary of Significant Accounting Policies

The Company has revised the following significant accounting policies.

Allowance for Loan Losses — The allowance for loan losses is established as management’s estimate of expected credit losses inherent in the Company’s lending activities and increased by the provision for credit losses and decreased by net charge-offs. The allowance for loan losses is evaluated quarterly by management based on regular reviews of the collectability of the loans. The Company develops and documents the allowance for loan losses methodology at the portfolio segment level — the commercial loan portfolio is comprised of C&I, CRE, multifamily residential, and construction and land loans; and the consumer loan portfolio is comprised of single-family residential, home equity lines of credit (“HELOCs”), and other consumer loans.

The allowance for loan losses represents the portion of a loan’s amortized cost basis that the Company does not expect to collect due to anticipated credit losses over the loan’s contractual life, adjusted for prepayments. The Company measures the expected loan losses on a collective pool basis when similar risk characteristics exist. Models consisting of quantitative and qualitative components are designed for each pool to develop the expected credit loss estimates. Reasonable and supportable forecast periods vary by loan portfolio. The Company has adopted lifetime loss rate models for the portfolios, which use historical loss rates and forecast economic variables to calculate the expected credit losses for each loan pool.

When loans do not share similar risk characteristics, the Company evaluates the loan for expected credit losses on an individual basis. Individually assessed loans include nonaccrual and troubled debt restructuring (“TDR”) loans. The Company evaluates loans for expected credit losses on an individual basis if, based on current information and events, it is probable that the Company will be unable to collect all amounts due according to the original contractual terms of the loan agreement. The following three different asset valuation measurement methods are available: (1) the present value of expected future cash flows, (2) the fair value of collateral less costs to sell, and (3) the loan's observable market price. The allowance for loan losses for collateral-dependent loans is determined based on the fair value of the collateral less costs to sell. For loans that are not collateral-dependent, the Company applies the present value of expected future cash flows valuation or the market value of the loan. When the loan is deemed uncollectible, it is the Company’s policy to promptly charge off the estimated credit losses.

The amortized cost of loans held-for-investment excludes accrued interest, which is included in Other assets on the Consolidated Balance Sheet. The Company has made an accounting policy election to not recognize an allowance for credit losses for accrued interest receivables as the Company reverses accrued interest if a loan is on nonaccrual status.

The allowance for loan losses is reported separately on the Consolidated Balance Sheet and the Provision for credit losses is reported on the Consolidated Statement of Income.

Allowance for Unfunded Credit Commitments — The allowance for unfunded credit commitments includes reserves provided for unfunded loan commitments, letters of credit, standby letters of credit (“SBLCs”) and recourse obligations for loans sold. The Company estimates the allowance for unfunded credit commitments over the contractual period in which the entity is exposed to credit risk via a present contractual obligation to extend credit. Within the period of credit exposure, the estimate of credit losses will consider both the likelihood that funding will occur, and an estimate of the expected credit losses on the commitments that are expected to fund over their estimated lives.

The allowance for unfunded credit commitments is maintained at a level believed by management to be sufficient to absorb estimated expected credit losses related to unfunded credit facilities. The determination of the adequacy of the allowance is based on periodic evaluations of the unfunded credit facilities. For all off-balance sheet instruments and commitments, the unfunded credit exposure is calculated using utilization assumptions based on the Company's historical utilization experience in related portfolio segments. Loss rates are applied to the calculated exposure balances to estimate the allowance for unfunded credit commitments. Other elements such as credit risk factors for loans outstanding, terms and expiration dates of the unfunded credit facilities, and other pertinent information are considered to determine the adequacy of the allowance.

The allowance for unfunded credit commitments is included in Accrued expenses and other liabilities on the Consolidated Balance Sheet. Changes to the allowance for unfunded credit commitments are included in Provision for credit losses on the Consolidated Income Statements.

Allowance for Credit Losses on Available-for-Sale Debt Securities — ASU 2016-13 modifies the OTTI model for AFS debt securities to apply an allowance approach for credit impairment as opposed to permanently writing down the cost basis of the security. For each reporting period, AFS debt security that is in an unrealized loss position is individually analyzed as part of the Company’s ongoing assessments to determine whether a fair value below the amortized cost basis has resulted from a credit loss or other factors. The initial indicator of impairment is a decline in fair value below the amortized cost, excluding accrued interest, of the AFS debt security. The Company first considers whether there is a plan to sell the AFS debt security or it is more-likely-than-not that it will be required to sell the debt security before recovery of the amortized cost. In determining whether an impairment is due to credit related factors, the Company considers the severity of the decline in fair value, nature of the security, the underlying collateral, the financial condition of the issuer, changes in the AFS debt securities’ ratings and other qualitative factors. For securities that are fully guaranteed by the U.S. government, or certain government enterprises, the Company believes that the credit loss exposure on these securities is remote and applies a zero credit loss assumption.

When the Company does not intend to sell the impaired AFS debt security and it is more-likely-than-not that the Company will not be required to sell the impaired debt security prior to recovery of its amortized cost basis, the credit component of the unrealized loss of the impaired AFS debt security is recognized as an allowance for credit losses, with a corresponding Provision for credit losses on the Consolidated Statement of Income and the non-credit component is recognized in Other comprehensive income (loss) on the Consolidated Statement of Comprehensive Income, net of applicable taxes. At each reporting period, the Company increases or decreases the allowance for credit losses as appropriate, while limiting reversals of the allowance for credit losses to the extent of the amounts previously recorded. If the Company intends to sell the impaired debt security or it is more-likely-than-not that the Company will be required to sell the impaired debt security prior to recovering its amortized cost basis, the entire impairment amount is recognized as an adjustment to the debt security’s amortized cost basis, with a corresponding Provision for credit losses on the Consolidated Statement of Income.

The amortized cost of the Company’s AFS debt securities excludes accrued interest, which is included in Other assets on the Consolidated Balance Sheet. The Company has made an accounting policy election to not recognize an allowance for credit losses for accrued interest receivables on AFS debt securities as the Company reverses any accrued interest if a debt security is impaired. As each AFS debt security has a unique security structure, where the accrual status is clearly determined when certain criteria listed in the terms are met, the Company assesses the default status of each security as defined by the debt security’s specific security structure.

Allowance for Collateral-Dependent Financial Assets — A financial asset is considered collateral-dependent if repayment is expected to be provided substantially through the operation or sale of the collateral. The allowance for credit losses is measured on an individual basis for collateral-dependent financial assets and determined by comparing the fair value of the collateral, minus the cost to sell, to the amortized cost basis of the related financial asset at the reporting date. Other than loans, collateral-dependent financial assets could also include resale agreements. In arrangements which the borrower must continually adjust the collateral securing the asset to reflect changes in the collateral’s fair value (e.g., resale agreements), the Company estimates the expected credit losses on the basis of the unsecured portion of the amortized cost as of the balance sheet date. If the fair value of the collateral is equal to or greater than the amortized cost of the resale agreement, the expected losses would be zero. If the fair value of the collateral is less than the amortized cost of the asset, the expected losses are limited to the difference between the fair value of the collateral and the amortized cost basis of the resale agreement.

Allowance for Purchased Credit Deteriorated Assets — ASU 2016-13 replaces the concept of PCI accounting under ASC 310-30 Receivables - Loans and Debt Securities Acquired with Deteriorated Credit Quality with the concept of purchased financial assets with credit deterioration. The Company adopted ASU 2016-13 using the prospective transition approach for Purchased credit deteriorated (“PCD”) assets that were previously classified as PCI assets. PCD financial assets are defined as acquired individual financial assets (or groups with similar risk characteristics) that as of the date of acquisition, have experienced a more-than-insignificant deterioration in credit quality since origination. For PCD debt securities and PCD loans, the company records the allowance for credit losses by grossing up the initial amortized cost, which includes the purchase price and the allowance for credit losses. The expected credit losses of PCD debt securities are measured at the individual security level. The expected credit losses for PCD loans are measured based on the loan’s unpaid principal balance. Beginning January 1, 2020, for any asset designated as a PCD asset at the time of acquisition, the Company estimates and records an allowance for credit losses, which is added to the purchase price to establish the initial amortized cost basis of the financial asset. Hence, there is no income statement impact from the acquisition. Subsequent changes in the allowance for credit losses on PCD assets will be recognized in Provision for credit losses on the Consolidated Statement of Income. The non-credit discount or premium will be accreted to interest income based on the effective interest rate on the PCD assets determined after the gross-up for the allowance for credit losses.

Troubled Debt Restructurings — The Company has implemented various loan modification programs to provide its borrowers relief from the economic impacts of the Coronavirus Disease 2019 (“COVID-19”). In accordance with the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”), the Company has elected to not apply TDR classification to any COVID-19 related loan modifications that were performed after March 1, 2020 to borrowers who were current as of December 31, 2019. For loans modified in response to the COVID-19 pandemic that do not meet the CARES Act criteria (e.g., current payment status as of December 31, 2019), the Company has applied the guidance included in “Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customer Affected by the Coronavirus (Revised)” (the “Interagency Statement”) issued by the federal banking regulators on April 7, 2020. The Interagency Statement states that loan modifications performed in light of the COVID-19 pandemic, including loan payment deferrals that are up to six months in duration, that were granted to borrowers who were current as of the implementation date of a loan modification program or modifications granted under government mandated modification programs, are not TDRs. The delinquency of the loans modified under the CARES Act and Interagency Statement is frozen at the time of the modification, and interest income continues to be recognized over the contractual life of the loan. For more information on the Company's TDR accounting, see Note 1 — Summary of Significant Accounting Principles — Troubled Debt Restructurings to the Consolidated Financial Statements of the Company’s 2019 Annual Report on Form 10-K.

Paycheck Protection Program — From April to August 2020, the Company accepted Paycheck Protection Program (“PPP”) applications and originated loans to qualified small businesses under the PPP established by the CARES Act. These loans are included in the C&I portfolio, carry an interest rate of 1%, and are 100% guaranteed by the Small Business Administration (“SBA”). No allowance for loan losses was recorded for these loans as of September 30, 2020. As of September 30, 2020, the Company funded over 7,400 SBA 7(a) approved PPP loans with an outstanding loan balance of $1.77 billion. The substantial majority of the Company’s PPP loans have a term of two years. The SBA paid the Company fees for processing PPP loans in the following amounts: (1) five percent for loans of not more than $350,000; (2) three percent for loans of more than $350,000 and less than $2,000,000; and (3) one percent for loans of at least $2,000,000. Loan processing fees paid to the Company by the SBA are accounted for as loan origination fees, where net deferred fees are recognized over the estimated life of the loan as a yield adjustment on the loans. Payments by borrowers on PPP loans begin ten months after the loan forgiveness covered period. Under the terms of the PPP, such loans are eligible to be forgiven if certain conditions are satisfied, in which case the SBA will make payments to the Company for the forgiven amounts. If a loan is paid off or forgiven by the SBA prior to its projected estimated life, the remaining unamortized deferred fees will be recognized as interest income in that period.
