Note 4 — Fair Value Measurements

The Company measures certain financial assets and liabilities at fair value on a recurring basis, including derivatives and available-for-sale securities. Fair value is the price the Company would receive to sell an asset or pay to transfer a liability in an orderly transaction with a market participant at the measurement date. The Company uses the three-level hierarchy established by the FASB that prioritizes fair value measurements based on the types of inputs used for the various valuation techniques (market approach, income approach and cost approach).

The levels of the fair value hierarchy are described below:


•	Level 1: Quoted prices in active markets for identical assets or liabilities.


•	Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly; these include quoted prices for similar assets or liabilities in active markets and quoted prices for identical assets or liabilities in markets that are not active.


•	Level 3: Unobservable inputs for which there is little or no market data available, which require the reporting entity to develop its own assumptions.

The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. Financial assets and liabilities are classified in their entirety based on the most conservative level of input that is significant to the fair value measurement.

Pricing vendors are utilized for certain Level 1 and Level 2 investments. These vendors either provide a quoted market price in an active market or use observable inputs without applying significant adjustments in their pricing. Observable inputs include broker quotes, interest rates and yield curves observable at commonly quoted intervals, volatilities and credit risks. The fair value of derivative contracts is determined using observable market inputs such as the daily market foreign currency rates, forward pricing curves, currency volatilities, currency correlations and interest rates and considers nonperformance risk of the Company and that of its counterparties.

The Company’s fair value processes include controls that are designed to ensure appropriate fair values are recorded. These controls include a comparison of fair values to another independent pricing vendor.

The following tables present information about the Company’s financial assets measured at fair value on a recurring basis as of November 30, 2016 and May 31, 2016, and indicate the level in the fair value hierarchy in which the Company classifies the fair value measurement.

The Company elects to record the gross assets and liabilities of its derivative financial instruments on the Unaudited Condensed 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 9 — 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 and other current assets, which would offset against the Company’s derivative liability balance (refer to Note 9 — 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 Unaudited Condensed Consolidated Statements of Cash Flows. Any amounts of non-cash collateral received, such as securities, are not recorded on the Unaudited Condensed Consolidated Balance Sheets pursuant to U.S. GAAP.

The following tables present information about the Company’s derivative assets and liabilities measured at fair value on a recurring basis as of November 30, 2016 and May 31, 2016, and indicate the level in the fair value hierarchy in which the Company classifies the fair value measurement.
