BASIS OF PRESENTATION

The Unaudited Condensed Consolidated Financial Statements include the accounts of NIKE, Inc. and its subsidiaries (the “Company” or “NIKE”) and reflect all normal recurring adjustments which are, in the opinion of management, necessary for a fair statement of the results of operations for the interim period. The year-end Condensed Consolidated Balance Sheet data as of May 31, 2021, was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America (“U.S. GAAP”). The interim financial information and notes thereto should be read in conjunction with the Company's latest Annual Report on Form 10-K for the fiscal year ended May 31, 2021. The results of operations for the three and six months ended November 30, 2021, are not necessarily indicative of results to be expected for the entire fiscal year.

Fair Value Measurements

The Company measures certain financial assets and liabilities at fair value on a recurring basis, including derivatives, equity securities and available-for-sale debt securities.

Hedging Derivatives

CASH FLOW HEDGESAll changes in fair value of derivatives designated as cash flow hedge instruments are recorded in Accumulated other comprehensive income (loss) until Net income is affected by the variability of cash flows of the hedged transaction. Effective hedge results are classified in the Unaudited Condensed Consolidated Statements of Income in the same manner as the underlying exposure. When it is no longer probable the forecasted hedged transaction will occur in the initially identified time period, hedge accounting is discontinued and the Company accounts for the associated derivative as an undesignated instrument as discussed below. Additionally, the gains and losses associated with derivatives no longer designated as cash flow hedge instruments in Accumulated other comprehensive income (loss) are recognized immediately in Other (income) expense, net, if it is probable the forecasted hedged transaction will not occur by the end of the initially identified time period or within an additional two-month period thereafter. In rare circumstances, the additional period of time may exceed two months due to extenuating circumstances related to the nature of the forecasted transaction that are outside the control or influence of the Company.

Undesignated Derivative Instruments

UNDESIGNATED DERIVATIVE INSTRUMENTSThe Company may elect to enter into foreign exchange forwards to mitigate the change in fair value of specific assets and liabilities on the Unaudited Condensed Consolidated Balance Sheets and/or embedded derivative contracts. These undesignated instruments are recorded at fair value as a derivative asset or liability on the Unaudited Condensed Consolidated Balance Sheets with their corresponding change in fair value recognized in Other (income) expense, net, together with the remeasurement gain or loss from the hedged balance sheet position and/or embedded derivative contract.

Embedded Derivatives

EMBEDDED DERIVATIVESEmbedded derivative contracts are treated as foreign currency forward contracts that are bifurcated from the related contract and recorded at fair value as a derivative asset or liability on the Unaudited Condensed Consolidated Balance Sheets with their corresponding change in fair value recognized in Other (income) expense, net, through the date the foreign currency fluctuations cease to exist.
