Basis of Presentation and Principles of Consolidation

In September 2019, we adopted a 52/53 week fiscal year consisting of four 13-week quarters ending on the first Sunday after January 30, which for fiscal 2021 was January 31, 2021 and for fiscal 2022 will be February 6, 2022. The third quarter of fiscal 2021 and 2022 ended on November 1, 2020 and October 31, 2021. Unless otherwise stated, all dates refer to our fiscal year and fiscal periods.

The condensed consolidated financial statements include the accounts of the Company and our wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

There were no material changes in the third quarter of fiscal 2022 to our significant accounting policies as described in our Annual Report on Form 10-K for fiscal 2021.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the financial statements and accompanying notes.

Fair Value Measurements

We define fair value as the exchange price that would be received from sale of an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. We measure our financial assets and liabilities at fair value at each reporting period using a fair value hierarchy which requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

Three levels of inputs may be used to measure fair value:

•Level 1 - Observable inputs are unadjusted quoted prices in active markets for identical assets or liabilities;

•Level 2 - Observable inputs are quoted prices for similar assets and liabilities in active markets or inputs other than quoted prices that are observable for the assets or liabilities, either directly or indirectly through market corroboration, for substantially the full term of the financial instruments; and

•Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. These inputs are based on our own assumptions used to measure assets and liabilities at fair value and require significant management judgment or estimation.
