FAIR VALUE MEASUREMENTS

The fair value of an asset is considered to be the price at which the asset could be sold in an orderly transaction between unrelated knowledgeable and willing parties. A liability's fair value is defined as the amount that would be paid to transfer the liability to a new obligor, rather than the amount that would be paid to settle the liability with the creditor. Assets and liabilities recorded at fair value are measured using a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers are:



•	Level 1 –	Observable inputs that reflect quoted prices in active markets
•	Level 2 –	Inputs other than quoted prices in active markets that are either directly or indirectly observable
•	Level 3 –	Unobservable inputs for which little or no market data exists, therefore requiring the Company to develop its own assumptions

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The assets and liabilities of the Company that are measured at fair value on a recurring basis as of July 31, 2016 and January 31, 2016 were as follows (amounts in millions):



	Fair Value at July 31, 2016 Using						Fair Value at January 31, 2016 Using
	Level 1		Level 2		Level 3		Level 1		Level 2			Level 3

Derivative agreements - liabilities	—		—		—		—		(82		)	—
Total	$	—	$	253	$	—	$	—	$	131		$	—

The Company uses derivative financial instruments from time to time in the management of its interest rate exposure on long-term debt and its exposure on foreign currency fluctuations. The fair value of the Company's derivative financial instruments was measured using level 2 inputs.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Long-lived assets were analyzed for impairment on a nonrecurring basis using fair value measurements with unobservable inputs (level 3). Impairment charges related to long-lived assets in the first six months of fiscal 2016 and 2015 were not material.

The aggregate fair value of the Company's senior notes, based on quoted market prices, was $23.7 billion and $21.8 billion at July 31, 2016 and January 31, 2016, respectively, compared to a carrying value of $20.1 billion and $20.1 billion at July 31, 2016 and January 31, 2016, respectively.
