We maintain cash and cash equivalents with banks that at times exceed applicable insurance limits. We reduce our exposure to credit risk by maintaining such deposits with high quality financial institutions. Concentration of credit risk with respect to accounts receivable is limited because a large number of geographically diverse customers comprise our customer base, thus spreading the trade credit risk. At April 30, 2013 and 2012, no single group or customer represented greater than 5% of total accounts receivable-trade. We manage credit risk through credit evaluations, credit limits and monitoring procedures. We may also use credit insurance from time to time. We perform ongoing credit evaluations of our customers, but generally do not require collateral to support accounts receivable-trade. Credit risk related to derivative instruments results from the fact we enter into interest rate derivative and commodity price hedge agreements with various counterparties. However, we monitor our derivative positions by regularly evaluating positions and the creditworthiness of the counterparties.</font></p> </div>

The guidance also requires that changes in the derivative’s fair value be recognized currently in earnings unless specific hedge accounting criteria are met. Our objective for utilizing derivative instruments is to reduce our exposure to fluctuations in cash flows due to changes in the commodity prices of recycled paper and adverse movements in interest rates.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">Our strategy to hedge against fluctuations in the commodity prices of recycled paper is to enter into hedges to mitigate the variability in cash flows generated from the sales of recycled paper at floating prices, resulting in a fixed price being received from these sales. We evaluate the hedges and ensure that these instruments qualify for hedge accounting pursuant to derivative and hedging guidance. Designated as effective cash flow hedges, the change in the fair value of these derivatives is recognized in other comprehensive income (loss) until the hedged item is settled and recognized as part of commodity revenue.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px; FONT-SIZE: 1px">  </p> <p style="MARGIN-TOP: 0px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">If the price per short ton of the underlying commodity, as reported on the Official Board Market, is less than the contract price per short ton, we receive the difference between the average price and the contract price (multiplied by the notional tons) from the respective counter-party. If the price of the commodity exceeds the contract price per short ton, we pay the calculated difference to the counter-party.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">The fair values of the commodity hedges are obtained or derived from third-party counter-parties and are determined using valuation models with assumptions about market prices for commodities being based on those in underlying active markets. We were not party to any commodity hedge contracts as of April 30, 2013 and 2012.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">Our strategy to hedge against fluctuations in variable interest rates involves entering into interest rate derivative agreements to hedge against adverse movements in interest rates. In fiscal year 2012, we entered into two forward starting interest rate derivative agreements, which we initially entered into to hedge the interest rate risk associated with a forecasted financing transaction to redeem our previously outstanding 11% senior second lien notes (the “Second Lien Notes”) effective January 15, 2013. The total notional amount of these interest rate derivative agreements is $150,000. The agreements require us to receive interest based on changes in the London Interbank Offered Rate (“LIBOR”) index and pay interest at a rate of approximately 1.40%. The agreements mature on March 15, 2016.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">For interest rate derivatives deemed to be effective cash flow hedges, the change in fair value is recorded in our stockholders’ equity as a component of accumulated other comprehensive loss and included in interest expense at the same time as interest expense is affected by the hedged transaction. Differences paid or received over the life of the agreements are recorded as additions to or reductions of interest expense on the underlying debt. For interest rate derivatives deemed to be ineffective cash flow hedges, the change in fair value is recorded through earnings and included in loss on derivative instruments.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">In the second quarter of fiscal year 2013, we dedesignated both of the $75,000 forward starting interest rate derivative agreements and discontinued hedge accounting in accordance with Accounting Standards Codification (the “ASC”) 815-30 because the interest payments associated with the forecasted financing transaction were no longer deemed probable due to the redemption of our Second Lien Notes as discussed in Note 10. We reclassified a $3,626 loss from accumulated other comprehensive loss to earnings as a loss on derivative instruments in fiscal year 2013.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">The fair values of the interest rate derivatives 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.</font></p> </div>

These estimates and assumptions affect the accounting for and recognition and disclosure of assets, liabilities, equity, revenues and expenses. We must make these estimates and assumptions because certain information that we use is dependent on future events, cannot be calculated with a high degree of precision given the available data or simply cannot be readily calculated. In the opinion of management, these consolidated financial statements include all adjustments, which include normal recurring and nonrecurring adjustments, necessary for a fair presentation of the financial position, results of operations, and cash flows for the periods presented. Summarized below are the estimates and assumptions that we consider to be significant in the preparation of our consolidated financial statements.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2"><b><i>Landfill Development Costs</i></b></font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">We estimate the total cost to develop each of our landfill sites to its remaining permitted and expansion capacity. This estimate includes such costs as landfill liner material and installation, excavation for airspace, landfill leachate collection systems, landfill gas collection systems, environmental monitoring equipment for groundwater and landfill gas, directly related engineering, capitalized interest, on-site road construction and other capital infrastructure costs. Additionally, landfill development includes all land purchases for landfill footprint and required landfill buffer property. The projection of these landfill costs is dependent, in part, on future events. The remaining amortizable basis of each landfill includes costs to develop a site to its remaining permitted and expansion capacity and includes amounts previously expended and capitalized, net of accumulated airspace amortization, and projections of future purchase and development costs. The interest capitalization rate is based on our weighted average interest rate incurred on borrowings outstanding during the period. Interest capitalized for the fiscal years ended April 30, 2013, 2012 and 2011 was $368, $407 and $1,078, respectively.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">Under life-cycle accounting, all costs related to acquisition and construction of landfill sites are capitalized and charged to expense based on tonnage placed into each site.

These criteria are evaluated annually by our engineers, accountants, lawyers, managers and others to identify potential obstacles to obtaining the permits. Once the remaining permitted and expansion airspace is determined in cubic yards, an airspace utilization factor (the “AUF”) is established to calculate the remaining permitted and expansion capacity in tons. The AUF is established using the measured density obtained from previous annual surveys. When we include the expansion airspace in our calculation of remaining permitted and expansion airspace, we include the projected costs for development, as well as the projected asset retirement costs related to capping, closure and post-closure of the expansion airspace in the amortization basis of the landfill.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">After determining the costs and the remaining permitted and expansion capacity at each of our landfills, we determine the per ton rates that will be expensed as waste is received and deposited at the landfill by dividing the costs by the corresponding number of tons. We calculate per ton amortization rates for assets associated with each capping event, for assets related to closure and post-closure activities and for all other costs capitalized or to be capitalized in the future for each landfill. These rates per ton are updated annually, or more frequently, as significant facts change.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2"><b><i>Landfill Capping, Closure and Post-Closure Costs</i></b></font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">The following is a description of our asset retirement activities:</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2"><i>Capping Costs.</i> Capping activities include the installation of liners, drainage, compacted soil layers and topsoil over areas of a landfill where total airspace has been consumed and waste is no longer being received. Capping activities occur throughout the life of the landfill. Our engineering personnel estimate the cost for each capping event based on the acreage to be capped and the capping materials and activities required. The estimates also consider when these costs would actually be paid and factor in inflation and discount rates. The engineers then quantify the landfill capacity associated with each capping event and the costs for each event are amortized over that capacity as waste is received at the landfill.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2"><i>Closure and Post-Closure Costs.</i> Closure and post-closure costs represent future estimated costs related to monitoring and maintenance of a solid waste landfill, after a landfill facility ceases to accept waste and closes. We estimate, based on input from our engineers, lawyers, accounting personnel and consultants, our future cost requirements for closure and post-closure monitoring and maintenance based on our interpretation of the technical standards of the Subtitle D regulations and the air emissions standards under the Clean Air Act of 1970, as amended, as they are being applied on a state-by-state basis. Closure and post-closure accruals for the cost of monitoring and maintenance include site inspection, groundwater monitoring, leachate management, methane gas control and recovery, and operation and maintenance costs to be incurred for a period which is generally for a term of 30 years after final closure of a landfill. In determining estimated future closure and post-closure costs, we consider costs associated with permitted and permittable ai<b>r</b>space.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px; FONT-SIZE: 1px">  </p> <p style="MARGIN-TOP: 0px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">Our estimate of costs to discharge capping, closure and post-closure asset retirement obligations for landfills are developed in today’s dollars. These costs are then inflated to the period of performance using an estimate of inflation which is updated annually (2.7% for fiscal years 2013 and 2012, respectively). Capping, closure and post-closure liabilities are discounted using the credit adjusted risk-free rate in effect at the time the obligation is incurred. The weighted average rate applicable to our asset retirement obligations at April 30, 2013 is between 8.5% and 10.0%, the range of the credit adjusted risk free rates effective since the adoption of guidance associated with asset retirement obligations in fiscal year 2004. Accretion expense is necessary to increase the accrued capping, closure and post-closure liabilities to the future anticipated obligation. To accomplish this, we accrete our capping, closure and post-closure accrual balances using the same credit-adjusted risk-free rate that was used to calculate the recorded liability. Accretion expense on recorded landfill liabilities is recorded to cost of operations from the time the liability is recognized until the costs are paid. Accretion expense on recorded landfill liabilities amounted to $3,538, $3,341 and $3,193 in fiscal years 2013, 2012 and 2011, respectively.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">We provide for the accrual and amortization of estimated future obligations for closure and post-closure based on tonnage placed into each site.

Surety bonds securing closure and post-closure obligations at April 30, 2013 and 2012 totaled $128,551 and $124,600, respectively. Letters of credit securing closure and post-closure obligations at April 30, 2013 and 2012 totaled $1,752. Restricted cash securing closure and post-closure obligations is disclosed in Note 5.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2"><b><i>Landfill Accounting-Landfill Operating Lease Contracts</i></b></font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">We entered into three landfill operation and management agreements in fiscal year 2004 and one landfill operation and management agreement in fiscal year 2006. These agreements are long-term landfill operating contracts with government bodies whereby we receive tipping revenue, pay normal operating expenses and assume future capping, closure and post-closure liabilities. The government body retains ownership of the landfill. There is no bargain purchase option and title to the property does not pass to us at the end of the lease term. We allocate the consideration paid to the landfill airspace rights and underlying land lease based on the relative fair values.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">In addition to up-front or one-time payments, the landfill operating agreements require us to make future minimum rental payments, including success/expansion fees, other direct costs and capping, closure and post closure costs. The value of all future minimum lease payments is amortized and charged to cost of operations over the life of the contract. We amortize the consideration allocated to airspace rights as airspace is utilized on a units-of-consumption basis and such amortization is charged to cost of operations as airspace is consumed (e.g., as tons are placed into the landfill). The underlying value of the land lease is amortized to cost of operations on a straight-line basis over the estimated life of the operating agreement.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2"><b><i>Environmental Remediation Liabilities</i></b></font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">We have recorded environmental liabilities representing our estimate of the most likely outcome of the matters for which we have determined that a liability is probable. These liabilities include potentially responsible party investigations, settlements, certain legal and consultant fees, as well as costs directly associated with site investigation and clean up, such as materials and incremental internal costs directly related to the remedy. We provide for expenses associated with environmental remediation obligations when such amounts are probable and can be reasonably estimated. We estimate costs required to remediate sites where it is probable that a liability has been incurred based on site-specific facts and circumstances. Estimates of the cost for the likely remedy are developed using third-party environmental engineers or other service providers. Where we believe that both the amount of a particular environmental remediation liability and timing of payments are reliably determinable, we inflate the cost in current dollars until the expected time of payment and discount the cost to present value.

If the fair value is less than its carrying value, then we would perform a second step and determine the fair value of the goodwill. In this second step, the fair value of goodwill is determined by deducting the fair value of a reporting unit’s identifiable assets and liabilities from the fair value of the reporting unit as a whole, as if that reporting unit had just been acquired and the purchase price were being initially allocated. If the fair value of the goodwill is less than its carrying value for a reporting unit, an impairment charge would be recorded to earnings.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">To determine the fair value of each of our reporting units as a whole we use discounted cash flow analyses, which require significant assumptions and estimates about the future operations of each reporting unit. Significant judgments inherent in this analysis include the determination of appropriate discount rates, the amount and timing of expected future cash flows and growth rates. The cash flows employed in our discounted cash flow analyses are based on financial forecasts developed internally by management. Our discount rate assumptions are based on an assessment of our risk adjusted discount rate, applicable for each reporting unit.

For example, a regulator may initially deny a landfill expansion permit application although the expansion permit is ultimately granted. In addition, management may periodically divert waste from one landfill to another to conserve remaining permitted landfill airspace. Therefore, certain events could occur in the ordinary course of business and not necessarily be considered indicators of impairment due to the unique nature of the waste industry.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">If an impairment indicator occurs, we perform a test of recoverability by comparing the carrying value of the asset or asset group to its undiscounted expected future cash flows. We group our long-lived assets for this purpose at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets or asset groups. If the carrying values are in excess of undiscounted expected future cash flows, we measure any impairment by comparing the fair value of the asset or asset group to its carrying value.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">To determine fair value, we use discounted cash flow analyses and estimates about the future cash flows of the asset or asset group. This analysis includes a determination of an appropriate discount rate, the amount and timing of expected future cash flows and growth rates. The cash flows employed in our discounted cash flow analyses are typically based on financial forecasts developed internally by management. The discount rate used is commensurate with the risks involved. We may also rely on third party valuations and or information available regarding the market value for similar assets.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">If the fair value of an asset or asset group is determined to be less than the carrying amount of the asset or asset group, impairment in the amount of the difference is recorded in the period that the impairment occurs. Estimating future cash flows requires significant judgment and projections may vary from the cash flows eventually realized.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">In the fourth quarter of fiscal year 2013, we initiated a plan to dispose of KTI Bio Fuels, Inc. (“Bio Fuels”), a construction and demolition material processing facility located in Lewiston, Maine, and as a result, the assets associated with Bio Fuels were classified as held-for-sale and the results of operations were recorded as loss from discontinued operations. Assets of the disposal group classified as held-for-sale include certain inventory and plant and equipment. We recognized a $3,261 charge associated with the adjustment of the disposal group to fair value as a loss from discontinued operations. The impairment was measured based on the asset group’s highest and best use using an in-exchange valuation premise under the market approach, utilizing the estimated purchase consideration of the asset group and consideration of costs to be incurred to sell. There are inherent judgments and estimates used in determining impairment charges and the actual sale of Bio Fuels may result in the recognition of an additional gain or loss. See Note 18 for further disclosure.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">In the fourth quarter of fiscal year 2012, we entered into negotiations regarding the sale of Maine Energy Recovery Company LP (“Maine Energy”). Based on the proposed purchase consideration, we reviewed the asset group for impairment and recorded a $40,746 impairment charge to the asset group within the Eastern region segment. The impairment was measured based on the asset group’s highest and best use under the market approach, utilizing the discounted present cash flows associated with the purchase consideration of the facility, adjusted for costs to demolish the facility. We used a discount rate of 3.5%, which approximates the buyer’s borrowing rate. In the first quarter of fiscal year 2013, we executed a purchase and sale agreement to sell the real property of Maine Energy to the City of Biddeford, Maine. In the third quarter of fiscal year 2013, we closed and initiated the decommissioning process of the facility.

Our accounts receivable – trade are recorded when billed or when related revenue is earned, if earlier, and represent claims against third-parties that will be settled in cash. The carrying value of our accounts receivable – trade, net of allowance for doubtful accounts, represents their estimated net realizable value. Estimates are used in determining our allowance for doubtful accounts and are based on our historical collection experience, current trends, credit policy and a review of our accounts receivable – trade by aging category. Our reserve is evaluated and revised on a monthly basis. Past-due receivables are written off when deemed to be uncollectible.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2"><b><i>Self-Insurance Liabilities and Related Costs</i></b></font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">We are self insured for vehicles and workers’ compensation. Our maximum exposure in fiscal year 2013 under the workers’ compensation plan is $1,000 per individual event, after which reinsurance takes effect. Our maximum exposure under the automobile plan is $750 per individual event, after which reinsurance takes effect. The liability for unpaid claims and associated expenses, including incurred but not reported losses, is determined by management with the assistance of a third-party actuary and reflected in our consolidated balance sheet as an accrued liability. We use a third-party to track and evaluate actual claims experience for consistency with the data used in the annual actuarial valuation. The actuarially determined liability is calculated based on historical data, which considers both the frequency and settlement amount of claims. Our self insurance reserves totaled $11,362 and $12,024 at April 30, 2013 and 2012, respectively. Our estimated accruals for these liabilities could be significantly different than our ultimate obligations if variables such as the frequency or severity of future events differ significantly from our assumptions.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2"><b><i>Income Tax Accruals</i></b></font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">We use estimates to determine our provision for income taxes and related assets and liabilities and any valuation allowance recorded against our net deferred tax assets. Valuation allowances have been established for the possibility that tax benefits may not be realized for certain deferred tax assets. Deferred income taxes are recognized based on the expected future tax consequences of differences between the financial statement basis and the tax basis of assets and liabilities, calculated using currently enacted tax rates. We record net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making this determination, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial operations. In the event we determine that we would be able to realize our deferred income tax assets in the future in excess of their net recorded amount, we will make an adjustment to the valuation allowance which would reduce the provision for income taxes.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">We account for income tax uncertainties according to guidance on the recognition, de-recognition and measurement of potential tax benefits associated with tax positions. We recognize interest and penalties relating to income tax matters as a component of income tax expense. See Note 15 for disclosure related to income taxes.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2"><b><i>Loss Contingencies</i></b></font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">We are subject to various legal proceedings, claims and regulatory matters, the outcomes of which are subject to significant uncertainty. We determine whether to disclose or accrue for loss contingencies based on an assessment of whether the risk of loss is remote, reasonably possible or probable, and whether it can be reasonably estimated. We analyze our litigation and regulatory matters based on available information to assess the potential liabilities. Management’s assessment is developed based on an analysis of possible outcomes under various strategies. We accrue for loss contingencies when such amounts are probable and reasonably estimable. If a contingent liability is only reasonably possible, we will disclose the potential range of the loss, if estimable. We record losses related to contingencies in cost of operations or general and administration expenses, depending on the nature of the underlying transaction leading to the loss contingency. See Note 11 for disclosure over loss contingencies.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2"><b><i>Stock-Based Compensation</i></b></font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">All share-based compensation cost is measured at the grant date, based on the estimated fair value of the award, and is recognized as expense over the employee’s requisite service period. Stock-based compensation expense is based on the number of awards ultimately expected to vest and is therefore reduced for an estimate of the awards that are expected to be forfeited prior to vesting.</font></p> <p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"><font style="FONT-FAMILY: Times New Roman" size="2">The fair value of each stock option is estimated using a Black-Scholes option pricing model, which requires extensive use of accounting judgment and financial estimation, including estimates of the expected term option holders will retain their vested stock options before exercising them and the estimated volatility of our common stock price over the expected term.
