FAIR VALUE MEASUREMENTS

Fair value can be measured using valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flow) and the cost approach (cost to replace the service capacity of an asset or replacement cost). Accounting standards utilize a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:


•	Level 1: Observable inputs such as quoted prices (unadjusted) 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 or similar assets or liabilities in markets that are not active.


•	Level 3: Unobservable inputs that reflect management’s own assumptions.

Our population of assets and liabilities subject to fair value measurements on a recurring basis at November 30, 2016 and 2015 are as follows:

The fair values of insurance contracts are based upon the underlying values of the securities in which they are invested and are from quoted market prices from various stock and bond exchanges for similar type assets. The fair values of bonds and other long-term investments are based on quoted market prices from various stock and bond exchanges. The fair values for interest rate and foreign currency derivatives are based on values for similar instruments using models with market based inputs.

The acquisition-date fair value of the liability for contingent consideration related to our acquisition of D&A was approximately $27.7 million (see note 2) and was included in other long-term liabilities in our consolidated balance sheet. The fair value of the liability both at acquisition and as of each reporting period is estimated using a discounted cash flow technique applied to the expected payout with significant inputs that are not observable in the market and thus represents a Level 3 fair value measurement as defined in the FASB's Accounting Standards Codification (ASC) 820, Fair Value Measurements and Disclosures. The significant inputs in the Level 3 measurement not supported by market activity included our probability assessments of expected future earnings before interest, taxes, depreciation and amortization related to our acquisition of D&A during the calendar 2017 earn-out period, adjusted for expectations of the amounts and ultimate resolution of likely disputes to be raised by the sellers and by us as provided in the purchase agreement, discounted considering the uncertainties associated with the obligation, and calculated in accordance with the terms of the purchase agreement. Changes in the fair value of the liability for contingent consideration including accretion, but excluding the impact of foreign currency, will be recognized in income on a quarterly basis until settlement in fiscal 2018.

The change in fair value of our Level 3 liabilities, which relates solely to the contingent consideration related to our acquisition of D&A, for the years ended November 30, 2016 and 2015 is summarized as follows (in millions):



	Beginning of year		Acquisition-date fair value		Settlements		Changes in fair value including accretion		Impact of foreign currency			Balance as of end of year

Year ended November 30, 2016	$	27.1	$	—	$	—	$	1.8	$	—		$	28.9
Year ended November 30, 2015	$	—	$	27.7	$	—	$	0.5	$	(1.1	)	$	27.1
