9.	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, trade receivables, 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 interest rate swaps, adjusted by the credit risk of us and our counter-parties based on observable credit default swap rates. We recognize all derivatives on the balance sheet at fair value.

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


	Fair Value Measurement at October 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	$	790	$	—	$	—

Liabilities:
Interest rate derivatives	$	—	$	2,177	$	—

As of April 30, 2014 our assets and liabilities 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 October 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”), the Vermont Economic Development Authority Solid Waste Disposal Long Term Revenue Bonds Series 2013 (“Vermont Bonds”), and the New Hampshire Bonds was approximately $382,460 and the carrying value was $373,400. 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, the Vermont Bonds and the New Hampshire Bonds is considered to be Level 2 within the fair value hierarchy as the fair value is determined using market approach pricing that utilizes pricing models and pricing systems, mathematical tools and judgment to determine the evaluated price for the security based on the market information of each of the bonds or securities with similar characteristics. As of October 31, 2014, the fair value of our Revolver is considered to be Level 2 within the fair value hierarchy as its fair value approximated its carrying value of $144,300 based on current borrowing rates for similar types of borrowing arrangements.
