Current Expected Credit Loss

In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The new guidance affects loans, debt securities, trade receivables, net investments in leases, off-balance-sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. The amended guidance requires the application of a current expected credit loss (“CECL”) model, which measures credit losses based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts. This ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. The Company adopted this guidance effective February 1, 2023, which was not material to the consolidated financial statements for the three months ended April 30, 2023.
