FAIR VALUE OF FINANCIAL INSTRUMENTS

12 Months Ended

Dec. 31, 2016

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 that we believe market participants would use in pricing an asset or a liability.

Assets and Liabilities Accounted for at Fair Value on a Recurring Basis

Our financial instruments include cash and cash equivalents, accounts receivable-trade, restricted cash and investments held in trust on deposit with various banks as collateral for our obligations relative to our landfill final capping, closure and post-closure costs and restricted cash reserved to finance certain capital projects, interest rate derivatives, trade payables and long-term debt. The carrying values of cash and cash equivalents, accounts receivable - trade and trade payables approximate their respective fair values due to their short-term nature. The fair value of restricted cash and investments held in trust, which are valued using quoted market prices, are included as restricted assets in the Level 1 tier below. The fair value of the interest rate derivative, included in the Level 2 tier below, was calculated based on a valuation obtained from our counter-party based primarily on the three month London Interbank Offered Rate yield curve that was observable at commonly quoted intervals for the full term of the swap. The interest rate derivative matured on March 15, 2016. We recognize all derivatives accounted for on the balance sheet at fair value. See Note 9, Long-Term Debt and Capital Leases for disclosure over the fair value of debt.

As of December 31, 2015, our financial assets and liabilities recorded at fair value on a non-recurring basis include our cost method investments in GreenerU and Recycle Rewards. The fair value of our cost method investment in GreenerU was measured by a third-party valuation specialist who completed a valuation analysis using a market approach based on an option pricing methodology that considers comparable publicly traded companies revenue multiples to determine an equity value and fair market value per share for GreenerU, which we used to properly value our cost method investment in GreenerU. The fair value of our cost method investment in RecycleRewards was measured by us when we completed a valuation analysis using an income approach based on discounted cash flows to determine an equity value for Recycle Rewards in order to properly value our cost method investment in Recycle Rewards.
