Accounting Policies |
Financing receivable modification | In connection with the implementation of the Accounting Standards Update (“ASU”) 2022-02, the Corporation has modified its policy related to loan modifications. As discussed in Note 3, the new accounting guidance eliminates the recognition and measurement principle of TDRs. The Corporation has also made changes to certain of its accounting policies related to its loans portfolio and allowance for credit losses in connection with this accounting standards update. A modification is subject to disclosure under the new ASU when the Corporation separately concludes that both of the following conditions exist: 1) the debtor is experiencing financial difficulties 2) the modification constitutes a reduction in the interest rate on the loan, a payment extension, a forgiveness of principal, or a more-than-insignificant payment delay. Determination that a borrower is experiencing financial difficulties involves a degree of judgment. The identification of loan modifications to debtors with financial difficulties is critical in the determination of the adequacy of the ACL. The ASU also eliminates the requirement to use a DCF approach to estimated credit losses for modified loans with borrowers experiencing financial difficulties. The entity can apply a methodology similar to the one used for loans that were not modified. The Corporation applied a modified retrospective transition method for the implementation of ASU 2022-02 which resulted in a reduction of approximately $ 46 million, $ 29 million net of tax, in the reserve which was recorded as an adjustment to the beginning balance of retained earnings. A loan modified with financial difficulties is typically in non-accrual status at the time of the modification. These loans continue in non-accrual status until the borrower has demonstrated a willingness and ability to make the restructured loan payments (at least six months of sustained performance after the modification (or one year for loans providing for quarterly or semi-annual payments)) and management has concluded that it is probable that the borrower would not be in payment default in the foreseeable future. Refer to Note 9 to the Consolidated Financial Statements for additional qualitative information on loan modifications and the Corporation’s determination of the ACL.
Loans | Loans Effective on January 1, 2023, newly originated mortgage loans held-for-sale are stated at fair value, with changes recorded through earnings. Previously held-for-sale were carried at the lower of its cost or market value. Fair value is generally determined in the aggregate and is measured based on current market prices for similar loans, outstanding investor commitments, prices of recent sales or discounted cash flow analyses which utilize inputs and assumptions which are believed to be consistent with market participants’ views.
Derivatives financial instruments | Derivative instruments Effective on January 1, 2023, the Corporation discontinued the hedge accounting treatment of certain forward contracts for which the changes in fair value were recorded, net of taxes, in accumulated other comprehensive income/(loss) and subsequently reclassified to net income (loss) in the same period that the hedged transaction impacted earnings. As a result of this change, the changes in the fair value of these forward contracts are being recorded through net income (loss). The Corporation utilizes forward contracts to hedge the sale of mortgage-backed securities with duration terms over one month. Interest rate forwards are contracts for the delayed delivery of securities, which the seller agrees to deliver on a specified future date at a specified price or yield. These forward contracts are hedging a forecasted transaction and thus qualify for cash flow hedge accounting. Based on the election to apply fair value accounting for its mortgage loans held for sale, effective on January 1, 2023, the Corporation discontinued the hedge accounting since the changes in the fair value of the loans is expected to be offset by the changes in the fair value of the forward contract, both of which are now recorded through net income (loss).
