[1] The cumulative effect of the change in accounting principle during the first quarter of fiscal year 2021 resulted from the adoption of accounting guidance that changed the methodology to be used when measuring credit losses for certain financial instruments and financial assets, including trade receivables. As a result of the adoption, the Company adjusted the opening balance of retained earnings for $24 million as of April 25, 2020.
