Current Expected Credit Losses
In June 2016, the Financial Accounting Standards Board (FASB) issued guidance which changes the methodology to be used to measure credit losses for certain financial instruments and financial assets, including trade receivables. The new methodology requires the recognition of an allowance that reflects the current estimate of credit losses expected to be incurred over the life of the financial asset. The Company adopted this guidance using the modified retrospective method in the first quarter of fiscal year 2021. The adoption of this guidance did not have a material impact to the Company’s consolidated financial statements.
