| Fair Value Measurements |
The following tables present information about the Company's financial assets measured at fair value on a recurring basis as of May 31, 2019 and 2018, and indicate the level in the fair value hierarchy in which the Company classifies the fair value measurement. Refer to Note 1 — Summary of Significant Accounting Policies for additional detail regarding the Company's fair value measurement methodology.
The Company elects to record the gross assets and liabilities of its derivative financial instruments on the Consolidated Balance Sheets. The Company's derivative financial instruments are subject to master netting arrangements that allow for the offset of assets and liabilities in the event of default or early termination of the contract. Any amounts of cash collateral received related to these instruments associated with the Company's credit-related contingent features are recorded in Cash and equivalents and Accrued liabilities, the latter of which would further offset against the Company's derivative asset balance (refer to Note 14 — Risk Management and Derivatives). Any amounts of cash collateral posted related to these instruments associated with the Company's credit-related contingent features are recorded in Prepaid expenses and other current assets, which would further offset against the Company's derivative liability balance (refer to Note 14 — Risk Management and Derivatives). Cash collateral received or posted related to the Company's credit related contingent features is presented in the Cash provided by operations component of the Consolidated Statements of Cash Flows. Any amounts of non-cash collateral received, such as securities, are not recorded on the Consolidated Balance Sheets pursuant to U.S. GAAP. For further information related to credit risk, refer to Note 14 — Risk Management and Derivatives. The following tables present information about the Company's derivative assets and liabilities measured at fair value on a recurring basis as of May 31, 2019 and 2018, and indicate the level in the fair value hierarchy in which the Company classifies the fair value measurement.
The Company's investment portfolio consists of investments in U.S. Treasury and Agency securities, time deposits, money market funds, corporate commercial paper and bonds. These securities are valued using market prices in both active markets (Level 1) and less active markets (Level 2).

The gross realized gains and losses on sales of securities were immaterial for the fiscal years ended May 31, 2019 and 2018. Unrealized gains and losses on available-for-sale debt securities included in Accumulated other comprehensive income (loss) were immaterial as of May 31, 2019 and 2018. The Company regularly reviews its available-for-sale debt securities for other-than-temporary impairment. For the years ended May 31, 2019 and 2018, the Company did not consider any of its securities to be other-than-temporarily impaired and, accordingly, did not recognize any impairment losses.

The Company's Level 3 assets comprise investments in certain non-marketable preferred stock. These Level 3 investments are an immaterial portion of the Company's portfolio and changes in these investments were immaterial during the years ended May 31, 2019 and 2018. No transfers among the levels within the fair value hierarchy occurred during the years ended May 31, 2019 or 2018. For additional information related to the Company's derivative financial instruments, refer to Note 14 — Risk Management and Derivatives. For fair value information regarding Notes payable and Long-term debt, refer to Note 7 — Short-Term Borrowings and Credit Lines and Note 8 — Long-Term Debt, respectively. The carrying amounts of other current financial assets and other current financial liabilities approximate fair value. As of May 31, 2019 and 2018, assets or liabilities required to be measured at fair value on a non-recurring basis were immaterial. |
