Recent Accounting and Regulatory Pronouncements |
Recent Accounting and Regulatory Pronouncements | Note 3 — Recent Accounting and Regulatory Pronouncements ​ Accounting Standards Adopted in 2020 In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This standard was subsequently updated with ASU No. 2019-11, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, ASU No. 2019-05, Targeted Transition Relief (Topic 326 – Financial Instruments-Credit Losses), and ASU No. 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments ASU 2016-13 requires an entity to utilize a new impairment model known as the current expected credit loss (“CECL”) model to estimate its lifetime “expected credit loss” and record an ACL that, when deducted from the amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset. The CECL model is expected to result in earlier recognition of credit losses for loans, investment securities portfolio, and purchased financial assets with credit deterioration. See Note 2 – Summary of Significant Account Policies – Allowance for Credit Losses for further discussion. We adopted the new standard as of January 1, 2020. This standard did not have a material impact on our investment securities portfolio at implementation. Related to the implementation of ASU 2016-13, we recorded additional ACL for loans of $54.4 million, deferred tax assets of $12.6 million, an additional reserve for unfunded commitments of $6.4 million and an adjustment to retained earnings of $44.8 million. See table the below for impact of ASU 2016-13 on the Company’s consolidated balance sheet. See Note 2 - Summary of Significant Accounting Policies for further discussion. ​

​ A – The Company did not have any held-to maturity securities as of January 1, 2020. Per our analysis we determined that no ACL was necessary for investment securities – available for sale. B – Accrued interest receivable from acquired credit impaired loans of $1,677 was reclassified to other assets and was offset by the reclassification of the grossed up credit discount on acquired credit impaired loans of $3,408 that was moved to the ACL for the purchased credit deteriorated loans. C – This is the calculated adjustment to the ACL related to the adoption of ASC 326. Additional reserve related to non-acquired loans was $34,049, to acquired loans was $16,981 and to purchased credit deteriorated loans was $3,408. D – This is the effect of deferred tax assets related to the adjustment to the ACL from the adoption of ASC 326 using a 22% tax rate. E – This is the adjustment to the reserve for unfunded commitments related to the adoption of ASC 326. F – This is the net adjustment to retained earnings related to the adoption of ASC 326. ​ ​ In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740) – Simplifying the Accounting for Income Taxes. The amendments in this update simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying the amending existing guidance. Some of the simplification items included are 1) simplification for intraperiod tax allocations where entities will determine the tax effect of pre-tax income or loss from continuing operations without consideration of the tax effect of other items that are not included in continuing operations, 2) simplification for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year allowing an entity to record a benefit for year-to-date loss in excess of its forecasted loss, and 3) simplify the accounting for income taxes by requiring that an entity recognize a franchise tax (or similar tax) that is partially based on income as an income-based tax and account for any incremental amount incurred as a non-income-based tax. This guidance is effective for interim and annual reporting periods beginning after December 15, 2020. Early adoption is permitted. The amendments related to franchise taxes that are partially based on income should be applied on either a retrospective basis for all periods presented or a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. All other amendments should be applied on a prospective basis. This update did not have a material impact on our consolidated financial statements. ​ Issued But Not Yet Adopted Accounting Standards In March 2020, FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848 – Facilitation of the Effects of Reference Rate Reform on Financial Reporting and subsequently expanded the scope of ASU No. 2020-04 with the issuance of ASU No. 2021-01. This update provides companies with optional guidance to ease the potential accounting burden associated with transitioning away from reference rates that are expected to be discontinued. The amendments in this Update provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this update apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The amendments in this update were effective for all entities as of March 12, 2020 through December 31, 2022. An entity may elect to apply the amendments in this update to eligible hedging relationships existing as of the beginning of the interim period that includes March 12, 2020 and to new eligible hedging relationships entered into after the beginning of the interim period that includes March 12, 2020. An entity may elect to apply the amendments for contract modifications as of any date from the beginning of an interim period that includes or is subsequent to March 12, 2020, or prospectively from a date within an interim period that includes or is subsequent to March 12, 2020, up to the date that the financial statements are available to be issued. Once elected, the amendments in this update must be applied prospectively for all eligible contract modifications and hedging relationships. The Company has established a LIBOR Committee and various subcommittees which are continuing to evaluate the impact of adopting ASU 2020-04 on the consolidated financial statements including evaluating all of its contracts, hedging relationships and other transactions that will be effected by reference rates that are being discontinued. ​ In August 2018, the FASB issued ASU No. 2018-14, Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans (Subtopic 715-20. ASU 2018-14 amends ASC 715-20 to add, remove, and clarify disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. For public business entities, ASU 2018-14 is effective for fiscal years ending after December 15, 2020 and requires entities to apply the amendment on a retrospective basis. Early adoption is permitted. This update will not have a material impact on our consolidated financial statements.
