7. FAIR VALUE OF FINANCIAL INSTRUMENTS

We use a three-tier fair value hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis, as well as assets and liabilities measured at fair value on a non-recurring basis, in periods subsequent to their initial measurement. These tiers include: Level 1, defined as quoted market prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; and Level 3, defined as unobservable inputs that are not corroborated by market data.

We use valuation techniques that maximize the use of market prices and observable inputs and minimize the use of unobservable inputs. In measuring the fair value of our financial assets and liabilities, we rely on market data or assumptions which we believe market participants would use in pricing an asset or a liability.

Assets and Liabilities Accounted for at Fair Value

Our financial instruments include cash and cash equivalents, restricted cash, accounts receivable-trade, restricted trust and escrow accounts held in trusts with various banks as collateral for our obligations relative to landfill final capping, closure and post-closure costs, interest rate derivatives, trade payables and long-term debt. The carrying values of cash and cash equivalents, restricted cash, trade receivables and trade payables approximate their respective fair values due to their short-term nature. The fair value of the restricted trust and escrow accounts are included as restricted assets in the Level 1 tier below. The fair values of the interest rate derivatives, included in the Level 2 tier below, are calculated based on the three month LIBOR yield curve that is observable at commonly quoted intervals for the full term of the swaps, adjusted by the credit risk of our counter-parties and us based on observable credit default swap rates. We recognize all derivatives on the balance sheet at fair value.

As of July 31, 2014 our assets and liabilities that are measured at fair value on a recurring basis included the following:


	Fair Value Measurement at July 31, 2014 Using:
	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Assets:
Restricted assets	$	703	$	—	$	—

Liabilities:
Interest rate derivatives	$	—	$	2,259	$	—

As of April 30, 2014 our assets and liabilities that are measured at fair value on a recurring basis included the following:


	Fair Value Measurement at April 30, 2014 Using:
	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Assets:
Restricted assets	$	681	$	—	$	—

Liabilities:
Interest rate derivatives	$	—	$	2,770	$	—

Fair Value of Debt

As of July 31, 2014, the fair value of our fixed rate debt, including our 7.75% senior subordinated notes due 2019 (“2019 Notes”), the Finance Authority of Maine Solid Waste Disposal Revenue Bonds Series 2005R-2 (“FAME Bonds 2005R-2”) and the Vermont Economic Development Authority Solid Waste Disposal Long Term Revenue Bonds Series 2013 (“Vermont Bonds”), was approximately $370,105 and the carrying value was $362,400. The fair value of the 2019 Notes is considered to be Level 1 within the fair value hierarchy as the fair value is based off of a quoted market price in an active market. The fair value of the FAME Bonds 2005R-2 and the Vermont Bonds are considered to be Level 2 within the fair value hierarchy as the fair values are determined using a discounted cash flow analysis based on current market rates for similar types of instruments taking into account our credit risk. Although we have determined the estimated fair value amounts of the FAME Bonds 2005R-2 and Vermont Bonds using available market information and a commonly accepted valuation methodology, considerable judgment is required in interpreting market data to develop the estimates of fair value. Accordingly, our estimates are not necessarily indicative of the amounts that we, or holders of these instruments, could realize in a current market exchange. The use of different assumptions and/or estimation methodologies could have a material effect on the estimated fair values. These amounts have not been revalued, and current estimates of fair value could differ significantly from the amounts presented.

As of July 31, 2014, the fair value of our 2011 senior secured revolving credit facility (“2011 Revolver”) is considered to be Level 2 within the fair value hierarchy as its fair value approximated its carrying value of $138,000 based on current borrowing rates for similar types of borrowing arrangements.

Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.
