Accounting Standards Update and Change in Accounting Principle [Abstract] |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies The accounting and reporting policies of the Corporation conform to U.S. GAAP and to general practice within the financial services industry. A discussion of these policies can be found in Note 1 Summary of Significant Accounting Policies included in the Corporation’s 2021 Annual Report on Form 10-K. As a result of the irrevocable election to account for MSRs under the fair value measurement methodology, as permitted under ASC 860-50-35-3, there has been a change to the Corporation's significant accounting policies since December 31, 2021, which is described below. Mortgage Servicing Rights The Corporation sells residential mortgage loans in the secondary market and typically retains the rights to service the loans sold. Upon sale, a MSRs asset is capitalized, which represents the then current fair value of future net cash flows expected to be realized for performing servicing activities. On January 1, 2022, the Corporation made the irrevocable election to account for its MSRs asset under the fair value measurement method. As a result of the change, a cumulative effect adjustment of $2 million, increasing retained earnings on the consolidated balance sheets, was recognized. Under this methodology, changes in the fair value are recognized in earnings as they occur through mortgage banking, net on the consolidated statements of income. MSRs are not traded in active markets. A cash flow model is used to determine fair value. Key assumptions and estimates, including projected prepayment speeds, assumed servicing costs, ancillary income, costs to service delinquent loans, costs of foreclosure, and discount rates with option-adjusted spreads, used by this model are based on current market sources. Assumptions used to value MSRs are considered significant unobservable inputs. A separate third-party model is used to estimate prepayment speeds based on interest rates, housing turnover rates, estimated loan curtailment, anticipated defaults and other relevant factors. Fair value estimates from outside sources are received periodically to corroborate the results of the valuation model. New Accounting Pronouncements Adopted There were no applicable material accounting pronouncements adopted by the Corporation since December 31, 2021. Future Accounting Pronouncements The expected impact of applicable material accounting pronouncements recently issued or proposed but not yet required to be adopted are discussed in the table below. To the extent that the adoption of new accounting standards materially affects the Corporation's financial condition, results of operations, or liquidity, the impacts are discussed in the applicable sections of this financial review.
Standard | Description | Date of anticipated adoption | Effect on financial statements
ASU 2022-02 Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures | The FASB issued these amendments to eliminate accounting guidance for TDRs by creditors in Subtopic 310-40, Receivables-Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty, and to require that an entity disclose current-period gross writeoffs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, Financial Instruments-Credit Losses-Measured at Amortized Cost. The amendments in this Update are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, and should be applied prospectively, except as provided in the next sentence. For the transition method related to the recognition and measurement of TDRs, an entity has the option to apply a modified retrospective transition method, resulting in a cumulative-effect adjustment to retained earnings in the period of adoption. Early adoption is permitted if an entity has adopted the amendments in Update 2016-03, including adoption in an interim period. | 1st Quarter 2023 | Adoption of this amendment is not expected to have a material impact on the Corporation's results of operation, financial position or liquidity, but will result in additional disclosure requirements related to gross charge offs by vintage year.
