FAIR VALUE DISCLOSURES

Assets and liabilities subject to fair value measurement are categorized into one of three different levels depending on the observability of the inputs employed in the measurement, as follows:


•	Level 1 – observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.


•	Level 2 – inputs that reflect quoted prices for identical assets or liabilities in markets which are not active; quoted prices for similar assets or liabilities in active markets; inputs other than quoted prices that are observable for the asset or liability; or inputs that are derived principally from or corroborated by observable market data by correlation or other means.


•	Level 3 – unobservable inputs reflecting the Company’s own assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available.

Non-recurring Fair Value Measurements

The majority of our non-financial assets, which include inventories, property and equipment, assets held for sale, goodwill and other intangible assets, are not required to be carried at fair value on a recurring basis. However, if certain triggering events occur such that a non-financial asset is required to be evaluated for impairment and deemed to be impaired, the impaired non-financial asset is recorded at its fair value.

The following table summarizes the assets as of June 30, 2015, valued at fair value on a non-recurring basis (in thousands):



	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Balance as of June 30, 2015		Total Loss for the Three Months Ended June 30, 2015
Inventories	$	—	$	13,922	$	—	$	13,922	$	(5,439	)
Assets held for sale	—		35,523		—		35,523		(9,862		)
Total assets	$	—	$	49,445	$	—	$	49,445	$	(15,301	)

The following table summarizes the assets as of June 30, 2014, valued at fair value on a non-recurring basis (in thousands):



	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Balance as of June 30, 2014		Total Loss for the Three Months Ended June 30, 2014
Assets held for sale	$	—	$	6,400	$	—	$	6,400	$	(2,579	)
Total assets	$	—	$	6,400	$	—	$	6,400	$	(2,579	)

The fair value of inventories using Level 2 inputs is determined by evaluating the current economic conditions for sale and disposal of spare parts, which includes estimates as to the recoverability of the carrying value of the parts based on historical experience with sales and disposal of similar spare parts, the expected timeframe of sales or disposals, the location of the spare parts to be sold and the condition of the spare parts to be sold or otherwise disposed of. The fair value of assets held for sale using Level 2 inputs is determined through evaluation of expected sales proceeds for aircraft. This analysis includes estimates based on historical experience with sales, recent transactions involving similar assets, quoted market prices for similar assets and condition and location of aircraft to be sold or otherwise disposed of. The loss for the three months ended June 30, 2015 related to nine aircraft held for sale and the loss for the three months ended June 30, 2014 related to four aircraft held for sale.

The rabbi trust investments consist of cash and mutual funds whose fair value are based on quoted prices in active markets for identical assets, and are designated as Level 1 within the valuation hierarchy. The rabbi trust holds investments related to our non-qualified deferred compensation plan for our senior executives.

The following table provides a rollforward of the contingent consideration liability Level 3 fair value measurements during the three months ended June 30, 2015 (in thousands):



	Significant Unobservable Inputs (Level 3)
Balance as of March 31, 2015	$	38,905
Change in fair value of contingent consideration	498
Payment of Cougar second year earn-out	(8,000		)
Balance as of June 30, 2015	$	31,403

We assess the estimated fair value of the contractual obligation to pay the contingent consideration on a quarterly basis and any changes in estimated fair value are recorded as accretion expense included in depreciation and amortization on our condensed consolidated statements of operations. Fluctuations in the fair value of contingent consideration are impacted by two unobservable inputs, management's estimate of the probability of Cougar or Airnorth achieving certain agreed performance targets and the estimated discount rate. As of June 30 and March 31, 2015, the discount rate approximated 4% for the contingent consideration related to Cougar and 2% for the contingent consideration related to Airnorth.
