	Business Operations
	ADS Waste Holdings, Inc. (the “Company” or “ADS Waste”) together with its consolidated subsidiaries, as a combined consolidated entity, is a regional environmental services company providing nonhazardous solid waste collection, transfer, recycling and disposal services to customers in the Southeast, Midwest and Eastern regions of the United States, as well as in the Commonwealth of the Bahamas.
	The Company currently manages and evaluates our principal operations through three reportable operating segments on a regional basis. Those operating segments are the South, East and Midwest regions which provide collection, transfer, disposal (in both solid waste and non-hazardous waste landfills), recycling services and billing services. Additional information related to our segments can be found in Note 22.
	The Company is a Delaware corporation that was formed to be the parent company for purposes of reorganizing several holding companies that is ultimately controlled by Star Atlantic Waste Holdings II, L.P. On September 19, 2012, in a series of transactions (the “Reorganization”), Star Atlantic Waste Holdings II, L.P., which is indirectly majority owned by funds sponsored and managed by Highstar Capital, L.P., contributed to Advanced Disposal Waste Holdings Corp. (parent company of ADS Waste Holdings, Inc.) (i) all of the stock of HWStar Holdings Corp., the parent company of Highstar Waste Holding Corp. and Subsidiaries, doing business as Interstate Waste Services (“IWS”) and (ii) its rights under a Share Purchase Agreement, dated as of July 18, 2012, to purchase all of the stock of Veolia ES Solid Waste, Inc. from Veolia Environnment. Advanced Disposal Waste Holdings Corp. contributed to ADS Waste all of the stock of ADStar Waste Holdings Corp. and of HWStar Holdings Corp., as well as the rights under the aforementioned Share Purchase Agreement to purchase the stock of Veolia ES Solid Waste, Inc. The Company is wholly owned by ADS Waste Holdings Corp. (the “Parent”).
	The Company is the parent holding company of the historical businesses of ADStar Waste Holdings Corp. and HW Star Holdings Corp., which through their ownership include the operating businesses of ADS and IWS, and has combined the results of these businesses. The historical financial information is derived from the historical consolidated financial statements of ADStar Waste Holdings Corp and the consolidated financial statements of HW Star Holdings Corp. The Reorganization was accounted for as a transaction between entities under common control as we have been and continue to be under common control of Highstar Capital, L.P. since 2006. The financial statements have been consolidated subsequent to the Reorganization date as described above.
	On November 20, 2012, ADS Waste purchased Veolia ES Solid Waste, Inc. from Veolia Environnment S.A. for $1,900 and changed the name to MWStar Holdings Corp (“Veolia ES Solid Waste division”). The consolidated company does business as ADS Waste Holdings, Inc.

Summary of Significant Accounting Policies	'
	2	Summary of Significant Accounting Policies
	Basis of Presentation
	The Company’s consolidated financial statements include its wholly-owned subsidiaries of Advanced Disposal Services South, Inc., Advanced Disposal Services East, Inc. and Veolia ES Solid Waste division and their respective subsidiaries.
	As required by accounting principles generally accepted in the United States of America for common control transactions, all assets and liabilities transferred to us as part of the Reorganization were recorded in the financial statements at carryover basis. For periods prior to the Reorganization, the combined consolidated financial statements and related notes reflect the Reorganization as if it had occurred in 2006, the date that ADStar Waste Holdings, Corp came under common control of Highstar Capital, L.P.
	For periods subsequent to the Reorganization, our consolidated financial statements include accounts and those of our majority-owned subsidiaries in which we have a controlling interest, after the elimination of intercompany accounts and transactions. All significant intercompany accounts and transactions have been eliminated in consolidation. The acquisition of the Veolia ES Solid Waste Division was accounted for as a purchase transaction and recorded at fair market value in accordance with current accounting guidance.
	Noncontrolling Interests
	In December 2007, the FASB issued authoritative guidance that established accounting and reporting standards for noncontrolling interests in subsidiaries and for the de-consolidation of a subsidiary. The guidance also established that a noncontrolling interest in a subsidiary is an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements. The Company owned 99.277% of HW Star Holdings Corp. as of December 31, 2012 and purchased the remaining interest in August 2013. As such, the Company has consolidated the results of the operations.
	Use of Estimates
	In preparing our financial statements that conform with accounting principles generally accepted in the United States of America, management uses estimates and assumptions that affect the amounts reported in these financial statements and accompanying notes. 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 from data available or simply cannot be readily calculated based on generally accepted methodologies. In preparing our financial statements, the more critical and subjective areas that deal with the greatest amount of uncertainty relate to our accounting for our long-lived assets, including recoverability, landfill development costs, and final capping, closure and post-closure costs, our valuation allowances for accounts receivable and deferred tax assets, our liabilities for potential litigation, claims and assessments, our liabilities for environmental remediation, stock compensation, accounting for goodwill and intangible asset impairments, deferred taxes, uncertain tax positions, self-insurance reserves, and our estimates of the fair values of assets acquired and liabilities assumed in any acquisition. Each of these items is discussed in more detail elsewhere in these Notes to the Consolidated Financial Statements. Our actual results may differ significantly from our estimates.
	Cash and Cash Equivalents
	Cash equivalents include highly liquid investments with original maturities of three months or less when purchased.
	Restricted Cash
	Restricted cash consists of amounts held for landfill closure and post-closure financial assurance. The balances will fluctuate based on changes in statutory requirements, future deposits made to comply with contractual arrangements, ongoing use of funds for qualifying events or the acquisitions or divestitures of landfills.
	Parts and Supplies Inventory
	Parts and supplies consist primarily of spare parts, fuel, tires, lubricants and processed recycled materials. Parts and supplies are stated at the lower of cost or market value utilizing an average cost method and are included in prepaid expenses and other current assets in the accompanying consolidated balance sheets.
	Revenue Recognition
	The Company recognizes revenues as the services are provided. Revenue is recognized as waste is collected, as tons are received at the landfill or transfer stations, as recycled commodities are delivered to a customer, or as services are rendered to customers. Certain customers are billed and pay in advance and, accordingly, recognition of the related revenues is deferred until the services are provided. Revenues are reported net of applicable state landfill taxes. No customer represented more than 5% of revenues for the years ended December 31, 2013, 2012 or 2011.
	Trade Receivables
	The Company records trade receivables when billed or when services are performed, as they represent claims against third parties that will generally be settled in cash. The carrying value of our receivables, net of the allowance for doubtful accounts, represents the estimated net realizable value. We estimate losses for uncollectible accounts based on an evaluation of the aged accounts receivable and the likelihood of collection of the receivable based on historical collection data and existing economic conditions. If events or changes in circumstances indicate that specific receivable balances may be impaired, further consideration is given to the collectability of those balances.
	Insurance Reserves
	The Company uses a combination of insurance with high deductibles and self-insurance for various risks including workers compensation, vehicle liability, general liability and employee group health claims. The exposure for unpaid claims and associated expenses, including incurred but not reported losses, is estimated by factoring in pending claims and historical trends data and other actuarial assumptions. In estimating our claims liability, we analyze our historical trends, including loss development and apply appropriate loss development factors to the incurred costs associated with the claims. The discounted estimated liability associated with settling unpaid claims is included in accrued expenses and other long-term liabilities in the consolidated balance sheets.
	Concentrations of Credit Risk
	Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, accounts receivable and derivative instruments. The Company maintains cash and cash equivalents with banks that at times exceed applicable insurance limits. The Company reduces its exposure to credit risk by maintaining such deposits with high quality financial institutions. The Company has not experienced any losses in such accounts.
	The Company generally does not require collateral on its trade receivables. Credit risk on accounts receivable is minimized as a result of the large and diverse nature of the Company’s customer base and its ability to discontinue service, to the extent allowable, to non-paying customers. No single customer represented greater than 5% of total accounts receivable at December 31, 2013 and 2012, respectively.
	Asset Impairments
	The Company monitors the carrying value of our long-lived assets for potential impairment and test the recoverability of such assets whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. These events or changes in circumstances, including management decisions pertaining to such assets, are referred to as impairment indicators. Typical indicators that an asset may be impaired include (i) a significant adverse change in legal factors in the business climate, (ii) an adverse action or assessment by a regulator, and (iii) a significant adverse change in the extent or manner in which a long-lived asset is being utilized or in its physical condition. 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. If cash flows cannot be separately and independently identified for a single asset, we will determine whether an impairment has occurred for the asset group for which we can identify the projected cash flows. 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. Fair value is generally determined by considering (i) internally developed discounted projected cash flow analysis of the asset or asset group; (ii) third-party valuations; and/or (iii) information available regarding the current market for similar assets. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying value exceeds the fair value of the asset.
	Property and Equipment, Net
	Property and equipment are recorded at cost, less accumulated depreciation. Expenditures for major additions and improvements are capitalized and maintenance activities are expensed as incurred. When property and equipment are retired, sold, or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts, and any resulting gain or loss is included in the results of operations. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Assets to be disposed of are reported at the lower of the carrying amount or fair value less cost to sell. Depreciation expense is calculated using the straight-line method over the estimated useful lives or the lease term, whichever is shorter. Estimated useful lives are as follows:
			Years
	Vehicles			5–10
	Machinery and equipment			3–10
	Containers			5–15
	Furniture and fixtures			5–7
	Building and improvements			5–39
	Leases
	We lease property and equipment in the ordinary course of our business. Our most significant lease obligations are for property and equipment specific to our industry, including real property operated as landfills and transfer stations. Our leases have varying terms. Some may include renewal or purchase options, escalation clauses, restrictions, penalties or other obligations that we consider in determining minimum lease payments. The leases are classified as either operating leases or capital leases, as appropriate.
	The majority of our leases are operating leases. This classification generally can be attributed to either (i) relatively low fixed minimum lease payments as a result of real property lease obligations that vary based on the volume of waste we receive or process or (ii) minimum lease terms that are much shorter than the assets’ economic useful lives. Management expects that in the normal course of business our operating leases will be renewed, replaced by other leases, or replaced with fixed asset expenditures. Our rent expense during each of the last three years and our future minimum operating lease payments for each of the next five years for which we are contractually obligated as of December 31, 2013 are disclosed in Note 14.
	Assets under capital leases are capitalized using interest rates determined at the inception of each lease and are amortized over either the useful life of the asset or the lease term, as appropriate, on a straight-line basis. The present value of the related lease payments is recorded as a debt obligation.
	From an operating perspective, landfills that are leased are similar to landfills we own because generally we own the landfill’s operating permit and will operate the landfill for the entire lease term, which in many cases is the life of the landfill. As a result, our landfill leases are generally capital leases. For landfill capital leases that provide for minimum contractual rental obligations, we record the present value of the minimum obligation as part of the landfill asset, which is amortized on a units-of-consumption basis over the shorter of the lease term or the life of the landfill. The one leased landfill was sold in fiscal 2013 (Note 4).
	Landfill Accounting
	Costs Basis of Landfill Assets — Landfills are typically developed in a series of cells, each of which is constructed, filled and capped in sequence over the operating life of the landfill. When the final cell is filled and the operating life of the landfill is completed, the cell must be capped and then closed and post-closure care and monitoring activities begin. Capitalized landfill costs include expenditures for land (which includes the land of the landfill footprint and landfill buffer property and setbacks) and related airspace associated with the permitting, development and construction of new landfills, expansions at existing landfills, landfill gas systems and landfill cell development. Landfill permitting, development and construction costs represent direct costs related to these activities, including land acquisition, engineering, legal and construction. These costs are deferred until all permits are obtained and operations have commenced at which point they are capitalized and amortized. If necessary permits are not obtained, costs are charged to operations. The cost basis of our landfill assets also includes asset retirement costs, which represent estimates of future costs associated with landfill final capping, closure and post-closure activities.
	Final Capping, Closure and Post-Closure Costs — The following is a description of our asset retirement activities and related accounting:
	Final Capping — Includes installing flexible membrane and geosynthetic clay liners, drainage and compact soil layers, and topsoil, and is constructed over an area of the landfill where total airspace capacity has been consumed and waste disposal operations have ceased. These final capping activities occur in phases as needed throughout the operating life of a landfill as specific areas are filled to capacity and the final elevation for that specific area is reached in accordance with the provisions of the operating permit. Final capping asset retirement obligations are recorded on a units-of-consumption basis as airspace is consumed related to the specific final capping event with a corresponding increase in the landfill asset. Each final capping event is accounted for as a discrete obligation and recorded as an asset and a liability based on estimates of the discounted cash flows and capacity associated with each final capping event.
	Closure and post-closure — These activities involve methane gas control, leachate management and groundwater monitoring, surface water monitoring and control, and other operational and maintenance activities that occur after the site ceases to accept waste. The post-closure period generally runs for 30 years after final site closure for landfills. Landfill costs related to closure and post-closure are recorded as an asset retirement obligation as airspace is consumed over the life of the landfill with a corresponding increase in the landfill asset. Obligations are recorded over the life of the landfill based on estimates of the discounted cash flows associated with performing the closure and post-closure activities.
	The Company updates annually its estimates for these obligations considering the respective State regulatory requirements, input from our internal engineers, operations, and accounting personnel and external consulting engineers. The closure and post-closure requirements are established under the standards of the U.S. Environmental Protection Agency’s Subtitle D regulations as implemented and applied on a state-by-state basis. These estimates involve projections of costs that will be incurred as portions of the landfill are closed and during the post-closure monitoring period.
	Capping, closure and post-closure costs are estimated assuming such costs would be incurred by a third party contractor in present day dollars and are inflated by the 20-year average change in the historical Consumer Price Index (consistent historical rate which agrees to historical CPI per government website of 2.50% from 1991 to 2012) to the time periods within which it is estimated the capping, closure and post-closure costs will be expended. We discount these costs to present value using the credit-adjusted, risk-free rate effective at the time an obligation is incurred, consistent with the expected cash flow approach. Any change that results in an upward revision to the estimated cash flows are treated as a new liability and discounted at the current rate while downward revisions are discounted at the historical weighted-average rate of the recorded obligation. As a result, the credit-adjusted, risk-free discount rate used to calculate the present value of an obligation is specific to each individual asset retirement obligation. The weighted-average rate applicable to our asset retirement obligations at December 31, 2013 is between 6.9% and 10.5%.
	The Company records the estimated fair value of the final capping, closure and post-closure liabilities for its landfills based on the capacity consumed in the current period. The fair value of the final capping obligations is developed based on the Company’s estimates of the airspace consumed to date for each final capping event and the expected timing of each final capping event. The fair value of closure and post-closure obligations is developed based on the Company’s estimates of the airspace consumed to date for the entire landfill and the expected timing of each closure and post-closure activity. Because these obligations are measured at estimated fair value using present value techniques, changes in the estimated cost or timing of future final capping, closure and post-closure activities could result in a material change in these liabilities, related assets and results of operations. The Company assesses the appropriateness of the estimates used to develop our recorded balances annually, or more often if significant facts change.
	Changes in inflation rates or the estimated costs, timing or extent of future final capping, closure and post-closure activities typically result in both (i) a current adjustment to the recorded liability and landfill asset; and (ii) a change in liability and asset amounts to be recorded prospectively over either the remaining capacity of the related discrete final capping event or the remaining permitted and expansion airspace (as defined below) of the landfill. Any changes related to the capitalized and future cost of the landfill assets are then recognized in accordance with our amortization policy, which would generally result in amortization expense being recognized prospectively over the remaining capacity of the final capping event or the remaining permitted and expansion airspace of the landfill, as appropriate. Changes in such estimates associated with airspace that has been fully utilized result in an adjustment to the recorded liability and landfill assets with an immediate corresponding adjustment to landfill airspace amortization expense.
	Interest accretion on final capping, closure and post-closure liabilities is recorded using the effective interest method and is recorded in operating expenses in the consolidated statements of operations.
	Amortization of Landfill Assets — The amortizable basis of a landfill includes (i) amounts previously expended and capitalized; (ii) capitalized and projected landfill final capping, closure and post-closure costs; (iii) projections of future acquisition and development costs required to develop the landfill site to its remaining permitted and expansion capacity; and (iv) land underlying both the footprint of the landfill and the surrounding required setbacks and buffer land.
	Amortization is recorded on a units-of-consumption basis, applying expense as a rate per ton. The rate per ton is calculated by dividing each component of the amortizable basis of a landfill by the number of tons needed to fill the corresponding asset’s airspace. For landfills that we do not own, but operate through operating or lease arrangements, the rate per ton is calculated based on expected capacity to be utilized over the lesser of the contractual term of the underlying agreement or the life of the landfill.
	Landfill site costs are depleted to zero upon final closure of a landfill. The Company develops our estimates of the obligations using input from our operations personnel, engineers and accountants and the obligations are based upon interpretation of current requirements and proposed regulatory changes and intended to approximate fair value. The estimate of fair value is based upon present value techniques using historical experience and, where available, quoted or actual market prices paid for similar work.
	The determination of airspace usage and remaining airspace is an essential component in the calculation of landfill asset depletion. This estimation is performed by conducting periodic topographic surveys, using aerial survey techniques, of the Company’s landfill facilities to determine remaining airspace in each landfill. The surveys are reviewed by the Company’s external consulting engineers, internal operating staff, and its management, financial and accounting staff.
	Remaining airspace will include additional “deemed permitted” or unpermitted expansion airspace if the following criteria are met:
		-1	The Company must either own the property for the expansion or have a legal right to use or obtain property to be included in the expansion plan;
		-2	Conceptual design of the expansion must have been completed;
		-3	Personnel are actively working to obtain land use and local and state approvals for an expansion of an existing landfill and the application for expansion must reasonably be expected to be received within the normal application and processing time periods for approvals in the jurisdiction in which the landfill is located;
		-4	There are no known significant technical, community, business, or political restrictions or similar issues that would likely impair the success of the expansion;
		-5	Financial analysis has been completed and the results demonstrate that the expansion has a positive financial and operational impact.
	Senior management must have reviewed and approved all of the above. Of our 42 active landfills, nine include deemed permitted airspace at December 31, 2013.
	Upon successful meeting of the preceding criteria, the costs associated with developing, constructing, closing and monitoring the total additional future capacity are considered in the calculation of the amortization and closure and post-closure rates.
	Once expansion airspace meets these criteria for inclusion in the Company’s calculation of total available disposal capacity, management continuously monitors each site’s progress in obtaining the expansion permit. If at any point it is determined that an expansion area no longer meets the required criteria, the deemed expansion airspace is removed from the landfill’s total available capacity, and the rates used at the landfill to amortize costs to acquire, construct, close and monitor the site during the post-closure period are adjusted prospectively. In addition, any amounts related to the probable expansion are charged to expense in the period in which it is determined that the criteria are no longer met.
	Once the remaining permitted and expansion airspace is determined in cubic yards, an airspace utilization factor (“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 and is then adjusted to account for future settlement. The amount of settlement that is forecasted will take into account several site-specific factors including: current and projected mix of waste type, initial and projected waste density, estimated number of years of life remaining, depth of underlying waste, anticipated access to moisture through precipitation or recirculation of landfill leachate and operating practices. In addition, the initial selection of the AUF is subject to a subsequent multi-level review by our engineering group, and the AUF used is reviewed on a periodic basis and revised as necessary. Our historical experience generally indicates that the impact of settlement at a landfill is greater later in the life of the landfill when the waste placed at the landfill approaches its highest point under the permit requirements.
After determining the costs and 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 each landfill for assets associated with each final capping event, for assets related to closure and post-closure activities and for all other costs capitalized or to be capitalized in the future. These rates per ton are updated annually, or more often, as significant facts change.
It is possible that the Company’s estimates or assumptions could ultimately be significantly different from actual results. In some cases the Company may be unsuccessful in obtaining an expansion permit or the Company may determine that an expansion permit that the Company previously thought was probable has become unlikely. To the extent that such estimates, or the assumptions used to make those estimates, prove to be significantly different than actual results, or the belief that the Company will receive an expansion permit changes adversely in a significant manner, the costs of the landfill, including the costs incurred in the pursuit of the expansion, may be subject to impairment testing and lower profitability may be experienced due to higher amortization rates, higher capping, closure and post-closure rates, and higher expenses or asset impairments related to the removal of previously included expansion airspace.
The assessment of impairment indicators and the recoverability of our capitalized costs associated with landfills and related expansion projects require significant judgment due to the unique nature of the waste industry, the highly regulated permitting process and the estimates involved. During the review of a landfill expansion application, a regulator may initially deny the expansion application although the permit is ultimately granted. In addition, management may periodically divert waste from one landfill to another to conserve remaining permitted landfill airspace, or a landfill may be required to cease accepting waste, prior to receipt of the expansion permit. However, such events occur in the ordinary course of business in the waste industry and do not necessarily result in an impairment of our landfill assets because, after consideration of all facts, such events may not affect our belief that we will ultimately obtain the expansion permit. As a result, our tests of recoverability, which generally make use of a cash flow estimation approach, may indicate that an impairment loss should be recorded. No landfill impairments were recorded for the year ended December 31, 2013. At December 31, 2012, one of our landfill sites was deemed to be impaired due to permitting issues and we recorded an impairment charge of approximately $43.7 for the year ended December 31, 2012 in the East region. We performed tests of recoverability for this landfill and the carrying value exceeded the undiscounted cash flows.
Capitalized Interest
The Company capitalizes interest on certain projects under development, including landfill construction projects. For the years ending December 31, 2013, 2012 and 2011, total interest cost was $163.7, $49.7 and $25.3, respectively, of which $0.6, $0.3 and $0.8 was capitalized.
Derivative Financial Instruments
The Company uses interest rate caps, swaps and call options to manage interest rate risk on its variable rate debt. The Company uses commodity derivatives to reduce the exposure of changes in diesel fuel and natural gas prices. The instruments qualifying for hedge accounting treatment have been designated as cash flow hedges for accounting purposes with changes in fair value, to the extent effective, recognized in accumulated other comprehensive income within the equity section of the consolidated balance sheets. Amounts are reclassified into earnings when the forecasted transaction affects earnings for the commodity derivatives. Any ineffectiveness for those instruments that do not qualify for hedge accounting, the amount of ineffectiveness or change in market value, respectively is recognized into earnings immediately without offset. The fair values of the derivatives are included in other current or long-term assets or other current or long term liabilities as appropriate. The Company obtains current valuations of its interest rate, fuel and natural gas hedging instruments from over-the-counter market quotes to determine the fair value of the outstanding derivatives.
Debt Issuance Costs
The costs related to the issuance of debt are capitalized and amortized to interest expense using either the straight-line method over the life of the related debt, which approximates the effective interest method or the effective interest method.
During fiscal 2013, the Company refinanced its Term B Loan and the transaction was accounted for as a modification of debt. The total amount of debt costs capitalized for the year ended December 31, 2013 was approximately $22.9 and there were no debt issuance costs written off for the year ended December 31, 2013. For the year ended December 31, 2012, the Company wrote-off approximately $9.4 of debt issuance costs related to the extinguishment of its revolving lines of credit and term loans, which was accomplished through an issuance of senior notes and refinancing of its revolving lines of credit and term loans in connection with the acquisition of Veolia ES Solid Waste division. For the year ended December 31, 2011, the Company wrote-off approximately $4.8 of debt issuance costs related to the extinguishment of outstanding Term Loan B, amendments to the credit facilities, refinancing of certain note obligations and revolving credit facilities. These transactions were accounted for as extinguishments and these charges are included in debt conversion costs and early extinguishment of debt in the consolidated statements of operations.
Debt issuance costs are amortized to interest expense during the year using the straight-line method or the effective interest method. For the years ended December 31, 2013, 2012 and 2011, the Company amortized $12.6, $5.0 and $2.7, respectively, of these costs to interest expense.
Acquisitions
The Company recognizes assets acquired and liabilities assumed in business combinations, including contingent assets and liabilities, based on fair values as of the date of acquisition. Any excess of purchase price over the fair value of the net assets acquired is recorded as goodwill.
In certain acquisitions, we agree to pay additional amounts to sellers contingent upon achievement by the acquired businesses of certain negotiated goals, such as targeted revenue levels, targeted disposal volumes or the issuance of permits for expanded landfill airspace. We have recognized liabilities for these contingent obligations based on their estimated fair value at the date of acquisition with any differences between the acquisition-date fair value and the ultimate settlement of the obligations being recognized as an adjustment to income from operations.
Assets and liabilities arising from contingencies such as pre-acquisition environmental matters and litigation are recognized at their acquisition-date fair value when their respective fair values can be determined. If the fair values of such contingencies cannot be determined, we report provisional amounts for which the accounting is incomplete.
Acquisition-date fair value estimates are revised as necessary and accounted for as an adjustment to income from operations if, and when, additional information becomes available to further define and quantify assets acquired and liabilities assumed. All acquisition-related transaction costs have been expensed as incurred.
Goodwill
Goodwill is the excess of the Company’s purchase price over the fair value of the net identifiable assets of acquired businesses. The Company does not amortize goodwill. Goodwill is subject to at least an annual assessment for impairment by evaluating quantitative factors.
The Company performs a quantitative assessment or two-step impairment test to determine whether a goodwill impairment exists at a reporting unit. The reporting units are equivalent to the Company’s segments and when an individual business within an integrated operating segment is divested, goodwill is allocated to that business based on its fair value relative to the fair value of its operating segment. The Company compares the fair value with its carrying amount to determine if there is potential impairment of goodwill. If the carrying value exceeds estimated fair value, there is an indication of potential impairment and the second step is performed to measure the amount of impairment. Fair value is estimated using an income approach based on forecasted cash flows. Fair value computed via this method is arrived at using a number of factors, including projected future operating results, economic projections, anticipated future cash flows and comparable marketplace data. There are inherent uncertainties related to these factors and to our judgment in applying them to this analysis. However, the Company believes that this method provides a reasonable approach to estimating the fair value of its reporting units.
The Company performs its annual assessment as of December 31 of each year. The impairment test indicated the fair value of each reporting unit exceeded the carrying value. If we do not achieve our anticipated disposal volumes, our collection or disposal rates decline, our costs or capital expenditures exceed our forecasts, costs of capital increase, or we do not receive landfill expansions, the estimated fair value could decrease and potentially result in an impairment charge in the future. Refer to Note 4 for information regarding impairment charges recorded in connection with discontinued operations. The Company recorded no goodwill impairment charges for the years ended December 31, 2013, 2012 and 2011, respectively.
Intangible Assets, Net
Intangible assets are stated at cost less accumulated amortization and consist of noncompete agreements, tradenames, customer contracts and customer lists and are amortized over their estimated useful lives. The carrying values of intangibles are periodically reviewed by management to determine if the facts and circumstances suggest that they may be impaired. If the carrying value exceeds estimated fair value, an impairment charge would be recognized in the amount of the excess. Fair value is typically estimated using an income approach for the respective asset, as described above. The Company recorded an impairment charge of $0.6 for the year ended December 31, 2013 related to discontinuance of a trade name. No such impairments have been identified for the years ended December 31, 2012 and 2011, respectively in connection with ongoing operations. Refer to Note 4 for information regarding impairment charges recorded in connection with discontinued operations.
Income Taxes
The Company is subject to income tax in the United States. Current tax obligations associated with the provision for income taxes are reflected in the accompanying consolidated balance sheets as a component of accrued expenses and the deferred tax obligations are reflected in deferred income tax asset or liability. Deferred income taxes arise from temporary differences resulting from income and expense items reported for financial accounting and tax purposes in different periods. Deferred income taxes are classified as current or noncurrent, depending on the classification of the assets and liabilities to which they relate. Deferred income taxes arising from temporary differences that are not related to an asset or liability are classified as current or noncurrent depending on the periods in which the temporary differences are expected to reverse. Significant judgment is required in assessing the timing and amounts of deductible and taxable items. We establish reserves for uncertain tax positions, when despite our belief that our tax return positions are fully supportable, we believe that certain positions may be challenged and potentially disallowed. When facts and circumstances change, we adjust these reserves through our provision for income taxes. To the extent interest and penalties may be assessed by taxing authorities on any underpayment of income tax, such amounts have been accrued and are classified as a component of tax expense in our consolidated statements of operations.
Contingencies
We are subject to various legal proceedings, claims and regulatory matters, the outcomes of which are subject to significant uncertainty. In general, 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 assess our potential liability relating to litigation and regulatory matters based on information available to us. Management develops its assessment 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 disclose the potential range of the loss, if estimable. (Note 20)
New Accounting Standards
In June 2011, the FASB issued ASU No. 2011-05, “Presentation of Comprehensive Income” (“ASU No. 2011-05”) to require other comprehensive income, including reclassification adjustments, to be presented with net income in one continuous statement or in a separate statement consecutively following the Consolidated Statement of Income. In December 2011, the FASB issued update ASC No. 2011-12, “Comprehensive Income: Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05” (“ASU No. 2011-12”) which requires deferral of only those changes in ASU No. 2011-05 that relate to the presentation of reclassification adjustments, and the paragraphs in this update supersede certain pending paragraphs in ASU No. 2011-05. ASU No. 2011-12 is effective for public entities for fiscal years, and interim periods within those years, beginning after December 15, 2011. For non-public entities, the amendments are effective for fiscal years ending after December 15, 2012, and interim and annual periods thereafter. The Company adopted this statement without impact on our consolidated financial statements other than in the presentation of comprehensive loss.
In September 2011, the FASB issued ASU 2011-08, Testing Goodwill for Impairment, amending Accounting Standards Codification (“ASC”) Topic 350, Intangibles — Goodwill and Other (“ASC 350”). The amendment permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test already required under ASC 350. The amendment is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted, including for annual and interim goodwill impairment tests performed as of a date before September 15, 2011, for nonpublic entities’ financial statements which have not yet been made available for issuance. The Company adopted this statement without impact on our consolidated financial statements.
In December 2011, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2011-11, “Disclosures about Offsetting Assets and Liabilities” (“ASU No. 2011-11”) to require new disclosures about offsetting assets and liabilities to help enable users of financial statements evaluate certain significant quantitative differences in balance sheets prepared under U.S. GAAP. ASU No. 2011-11 is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The adoption did not have a material impact on the consolidated financial statements.
In February 2013, the Financial Accounting Standards Board (“FASB”) issued amended authoritative guidance associated with comprehensive income, which requires companies to provide information about the amounts that are reclassified out of accumulated other comprehensive income by component. Additionally, companies are required to present significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. The amendment to authoritative guidance associated with comprehensive income was effective for the Company on January 1, 2013. The adoption of this guidance did not have a material impact on our consolidated financial statements. We have presented the information required by this amendment in Note 24.
Reclassifications
When necessary, reclassifications have been made to our prior period consolidated financial information in order to conform to the current year presentation.

Acquisitions	'
	3	Acquisitions
	For the year ended December 31, 2013, the Company completed the acquisitions of seventeen collection companies. Consideration transferred amounted to approximately $31.3 for these acquisitions during fiscal 2013, of which consideration in the form of a note payable was provided to the seller in the amount of $1.5. Transaction costs related to these acquisitions were not significant for the year ended December 31, 2013.
	As discussed in Note 1 to the consolidated financial statements, effective November 20, 2012, ADS Waste acquired the stock of Veolia ES Solid Waste division from Veolia Environnment S.A. for a purchase price of approximately $1.9 billion subject to a working capital and net company debt adjustment which was completed within one year from date of purchase. In September 2013, the Company paid an additional $20.6 related to the working capital and net Company debt adjustment and in November 2013 completed the final opening balance sheet adjustments which were not significant. Approval of the transaction by the United States Department of Justice was granted pursuant to a consent decree issued in November 2012, provided the Company sell certain assets, including one landfill and two transfer stations in Central Georgia, three commercial waste collection routes in the Macon, Georgia area and three transfer stations in northern New Jersey and the assets are classified as held for sale in the consolidated financial statements at December 31, 2012. The sale of those assets was completed in fiscal 2013 (Note 4). Transaction costs incurred in connection with the acquisition were approximately $26.5.
	Furthermore, the Company acquired the assets and assumed certain liabilities of five collection companies and one landfill during the year ended December 31, 2012. Consideration transferred amounted to approximately $28.7 for these acquisitions during fiscal 2012, of which consideration in the form of a note payable was provided to the seller in the amount of approximately $3.1.
	The results of operations of each acquisition are included in the consolidated statements of operations of the Company subsequent to the closing date of each acquisition.

	The following table summarizes the fair value of derivative instruments recorded in our combined consolidated balance sheets.

	We have not offset fair value amounts recognized for our derivative instruments. Changes in fair value attributable to derivative instruments that are not accounted for as hedging instruments were not significant for the years ended December 31, 2013, 2012 and 2011, respectively.
	Interest Rate Swaps
	We have used interest rate swaps to maintain a portion of our debt obligations at fixed market interest rates. These interest rate derivatives qualify for hedge accounting. In November 2012, we terminated these interest rate swaps in connection with our debt refinancing (Note 13) and paid approximately $7.0 upon termination. The amounts were deferred in accumulated other comprehensive income upon termination and are being amortized to interest expense over the remaining term of the original swap. The cash paid upon termination of the swaps have been classified as a change in other liabilities within “net cash provided by operating activities” in the consolidated statement of cash flows. The interest rate swap agreements that do not qualify for hedge accounting increased (decreased) net interest expense by $0, $0.2 and $(0.8) for the years ended December 31, 2013, 2012 and 2011, respectively.
	The Company also recognizes the impacts of the amortization of previously terminated interest rate swap agreements as adjustments to interest expense. The following table summarizes the impacts of periodic settlements of terminated swap agreements on the Company’s results of operations:
			Statement of Operations	Year Ended December 31,
			Classification	2013		2012		2011
	Terminated swap agreements		Interest expense	$	6	$	1	$	—
	Interest Rate Cap
	In December 2012, the Company entered into four interest rate cap agreements to hedge the risk of a rise in interest rates and associated cash flows on the variable rate debt. The Company recorded the premium of $5.0 in other assets in the combined consolidated balance sheet and amortizes the premium to interest expense based upon decreases in time value of the caps. Amortization expense was approximately $1.3 for the year ended December 31, 2013. The original notional amounts of the contracts aggregated are approximately $1,212.0 at December 31, 2013 and expire in tranches through 2016.
	Interest Rate Call Option
	In 2010, the Company entered into an interest rate call option transaction to manage the interest rate risk for the years ended December 31, 2012 and 2011, respectively. The Company recorded the call option premium of $0.8 to other current assets and other assets, as applicable, in the combined consolidated balance sheet and amortized the premium ratably over the effective dates of the transaction. The Company amortized approximately $0.4 of the call option premium to interest expense for each of the years ended December 31, 2012 and 2011. The notional amount of the contract was $100.0 and had a strike price of 3.5% based upon three-month LIBOR.
	Commodity Derivatives
	The market price of diesel fuel and natural gas is unpredictable and can fluctuate significantly. Significant volatility in the price of fuel or natural gas could adversely affect the business and reduce the Company’s operating margins. To manage a portion of that risk, the Company entered into commodity swap agreements related to the Company’s collection assets during 2012 and 2011. We hedged approximately 7.3 gallons of fuel with strike prices ranging from $2.79 to $3.04, of which 1.1 gallons remain under hedge contracts at December 31, 2013. Further, the Company entered into put options to reduce the exposure of a decrease in natural gas prices. We hedged approximately 0.5 base trade units of natural gas with strike price of $5.10 which expired by December 31, 2013.
	There was no significant ineffectiveness associated with our cash flow hedges during the years ended December 31, 2013, 2012 or 2011.

	In October 2012, the Company placed $1,800 in term B loans, $550 in bonds and a $300 revolving credit facility. The proceeds were used to finance the acquisition of Veolia ES Solid Waste division and repay borrowings under its previously outstanding revolving credit facility and extinguish term loans and notes payable. Substantially all of the Company’s assets collateralize the loans, bonds and credit facility and each of the agreements restrict further indebtedness and payment of dividends in excess of certain predefined amounts.
	All borrowings under the term B loan and the Revolver are guaranteed by each of the Company’s current and future U.S. subsidiaries (which also guarantee the 8.25% bonds), subject to certain agreed-upon exemptions. The Company has one non-guarantor foreign subsidiary that is minor, as its assets, revenue, income from continuing operations and cash flows from operating activities are less than 3% of the Company’s consolidated amounts. All guarantors are jointly and severally and fully and unconditionally liable. The parent company has no independent assets or operations and each of the subsidiary guarantor is 100% owned by the Company. There are no significant restrictions on the Company or any guarantor to obtain funds from its subsidiaries by dividend or loan.
	The Revolver is a syndicated revolving credit facility that is available for general corporate purposes including working capital, equipment purchases and business acquisitions and collateralized by the real property of the Company. It is due at maturity in October 2017. At December 31, 2013, the Revolver had $8.0 in borrowings outstanding and $70.7 in letters of credit outstanding. At December 31, 2012, the Revolver facility had no borrowings outstanding and $75.0 in outstanding letters of credit. An annual commitment fee equal to 0.50% per annum on the daily unused amount is due quarterly. The amount of fees for 2013, 2012 and 2011 were not significant.
	The term B loan is due in September 2019 and has payments due quarterly of $4.5 with mandatory prepayments due to the extent net cash proceeds from the sale of assets exceed $25.0 in any fiscal year and are not reinvested in the business within 365 days from the date of sale, upon notification of the Company’s intent to take such action. The term B loan is collateralized by certain real property of the Company. Further prepayments are due when there is excess cash flow, as defined.
	The bonds are redeemable prior to October 1, 2015 at a price equal to 108.25% of the principal plus accrued interest for up to 35% of the issuance. On October 1, 2016 and 2017, the notes may be redeemed for a call premium of 104.125% and 102.063%, respectively. Subsequent to October 1, 2018, the notes are redeemable at par. The bonds bear interest at 8.25% and are due in October 2020.
	The Revolver and term B loan bear interest at a base rate (alternate base rate or LIBOR base rate) plus an applicable margin. The alternate base rate is defined as the greater of the prime rate or federal funds rate plus 50 basis points and the LIBOR base rate is subject to a 1.25% floor.
	The applicable margin for the term loan B is based on the total leverage ratio of the Company as follows:
	Total Leverage Ratio		LIBOR Base Rate		Alternate Base Rate
	<4.75:1.00		2.50%		2.50%
	³4.75:1.00		3.00%		3.00%
	The applicable margin for the Revolver is based on the total leverage ratio of the Company as follows:
	Total Leverage Ratio		LIBOR Base Rate		Alternate Base Rate
	<4.75:1.80		3.50%		2.50%
	³4.75:1.00		4.00%		3.00%
	Fair Value of Debt
	The fair value of the Company’s debt is estimated using discounted cash flow analyses, based on rates the Company would currently pay for similar types of instruments except for variable rate debt for which cost approximates fair value due to the short-term nature of the interest rate (Level 2 inputs). Although the Company has determined the estimated fair value amounts using available market information and commonly accepted valuation methodologies, considerable judgment is required in interpreting the information and in developing the estimated fair values. Therefore, these estimates are not necessarily indicative of the amounts that the Company, or holders of the instruments, could realize in a current market exchange. The fair value estimates are based on information available as of December 31, 2013 and 2012, respectively.
	The estimated fair value of our debt is as follows at December 31:
			2013			2012
	Senior notes		$	596.1		$	593.3
	Term loan B			1,788.10			1,818.00
			$	2,384.20		$	2,411.30
	The carrying value of the debt at December 31, 2013 is approximately $2,332.0 compared to $2,350.0 at December 31, 2012.

Stockholders' Equity and Stock Options	'
	15	Stockholders’ Equity and Stock Options
	(Share amounts not in millions)
	The Company’s equity consists of one thousand shares of authorized, issued and outstanding common stock.
	In October 2012, the Parent’s Board of Directors adopted the 2012 Stock Incentive Plan (the “Plan”) under which an aggregate of 150,000 shares of the Parent’s common stock was reserved for issuance. The Plan provides for employees of the Company to participate in the plan and provides that the options or stock purchase rights have a term of ten years and vest equally over four years at a rate of 20% with 20% of the options being vested at the date of grant for all options except the Strategic grants which vest 100% after five years. All options of the Strategic Plan issued prior to 2010 vest immediately upon a change of control. All other options vest in 20% tranches from the date of issuance upon a change of control. This 2012 Plan replaced the 2006 Plan of Advanced Disposal Services South, Inc. All outstanding options under the 2006 Plan were cancelled and reissued under the 2012 Plan. The incremental compensation expense associated with the exchange is immaterial.
	These options have an assumed forfeiture rate ranging from 4%-6% for 2013 and 2012.
	On December 31, 2008, senior management exercised 71,941 of outstanding stock options. Certain members of senior management issued promissory notes to Advanced Disposal Services South, Inc. for $28.0 to complete the stock option transaction. Interest began accruing at December 31, 2008 semi-annually. In conjunction with the Reorganization, the notes were restructured and bear interest at a rate of 0.89% which was the Applicable Federal Rate in effect at the time of restructuring the notes at December 31, 2012. As the rate is considered below market, compensation expense in the amount of approximately $0.3 and $0.4 was recognized for the years ended December 31, 2013 and 2012, respectively. The principal and interest of the promissory notes are due on the earliest of the tenth anniversary of the issuance of the stock option awards, sale of the Company or termination of employment. The Company has included the interest income of $0.8 and $0.8 in other income in the consolidated statements of operations for the years ended December 31, 2012 and 2011, respectively. The notes were distributed to Advanced Disposal Waste Holdings Corp. in connection with the Reorganization during 2012.
	Stock Option Plans
	The fair value of the options granted is estimated using the Black-Scholes option pricing model using the following assumptions:
			2013			2012		2011
	Average expected term (years)			6			6		6
	Risk-free interest rate			0.93	%		1.09% - 1.36%		2.06% - 2.58%
	Expected volatility			20	%		22.4% - 25.1%		29.30%
	Since the Company does not have any historical exercise data that is indicative of expected future exercise performance, it has elected to use the “simplified method” to estimate the options expected term by taking the average of each vesting-tranche and the contractual term. The Company used the average weekly historical volatility for public companies in the solid waste sector to estimate historical volatility used in the Black-Scholes model. The risk-free rate used was based on the US Treasury security rate estimated for the expected term of the option at the date of grant. The Company has applied a discount for lack of marketability ranging from 9% to 20% for shares issued in 2013, 2012 and 2011, to the option value as the shares being valued are privately held and not readily marketable.
	Annual Stock Options
	A summary of the Senior Management Stock Options and Annual Stock Options outstanding for the year ended December 31, 2013 (in millions, except share and per share amounts) is as follows:

	The Company has 401(k) Savings Plans (“401(k) Plan”) for the benefit of qualifying full-time employees who have more than one year of service and are over 21 years of age. Employees make pre-tax contributions to the 401(k) Plan with a partial matching contribution made by the Company. The Company’s matching contributions to the 401(k) Plan were $2.8, $1.9 and $1.4 for the years ended December 31, 2013, 2012 and 2011, respectively. Contributions by the Company are included in operating costs and expenses in the accompanying consolidated statements of operations.
	The Company is a participating employer in a number of trustee-managed multiemployer, defined benefit pension plans for employees who participate in collective bargaining agreements. Approximately 12% of the Company’s workforce is subject to a collective bargaining agreement and five of the collective bargaining agreements expire within one year. The risks of participating in the multiemployer plans are different from single-employer plans in that (i) assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers; (ii) if a participating employers stops contributing to the plan, the unfunded obligations of the plan may be required to be assumed by the remaining participating employers; and (iii) if we choose to stop participating in any of our multiemployer plans, we may be required to pay those plans a withdrawal amount based on the underfunded status of the plan.

	(A)	The employers contributions to the plan represent greater than 5% of the total contributions to the plan for the most recent plan year available.
	(B)	A multi-employer defined benefit pension plan that has been certified as endangered, seriously endangered, or critical may begin to levy a statutory surcharge on contribution rates. Once authorized, the surcharge is at the rate of 5% for the first 12 months and 10% for any periods thereafter. Contributing employers, however, may eliminate the surcharge by entering into a collective bargaining agreement that meets the requirements of the applicable funding improvement plan or rehabilitation plan.

	Net deferred tax liability		$	(240.4	)	$	(298.0	)
	The amounts recorded as deferred tax assets as of December 31, 2013 and 2012 represent the amounts of tax benefits of existing deductible temporary differences or net operating loss carryforwards (“NOLs”). Realization of deferred tax assets is dependent upon the generation of sufficient taxable income prior to expiration of any loss carryforwards. A valuation allowance has been recorded against deferred tax assets as of December 31, 2013 in the amount of $141.6. The valuation allowance for the year ended December 31, 2012 was $128.1. We have established valuation allowances for uncertainties in realizing the benefit of certain tax loss and credit carryforwards and other deferred tax assets. While we expect to realize the deferred tax assets, net of the valuation allowances, changes in estimates of future taxable income or in tax laws may alter this expectation.
	The Company had available federal NOL carryforwards from continuing operations of approximately $408.3 and $257.4 at December 31, 2013 and 2012, respectively. The Company’s federal net operating losses have expiration dates beginning in the year 2014 through 2033, if not previously utilized against taxable income.
	The Company has grown through a series of acquisitions and mergers. IWS has had change of control events that resulted in limitations on the utilization of NOLs pursuant to Section 382 of the Internal Revenue Code (“IRC”).
	Approximately $184.5 of the NOLs from continuing operations of IWS are limited under the “Separate Return Loss Year” (“SRLY”) rules of the IRC. These NOLs are available to be utilized against taxable income of the IWS group only. At this time, the Company does not expect to utilize these NOLs.
	The predecessor of IWS had a transaction on June 2, 2002 that was treated as a reorganization. As such, IWS may be precluded from utilizing all or a portion of its federal and state NOLs originating prior to the ownership change. The Company estimates that it is subject to an annual limitation of approximately $3.5 on NOLs of approximately $123.6 originating prior to June 28, 2002. IWS had a subsequent change of control on November 1, 2005. As such, NOLs of $4.8 originating after June 28, 2002 through November 1, 2005 are subject to an annual limitation of $4.2.
	A reconciliation of the beginning and ending amount of gross unrecognized tax benefits for 2013, 2012 and 2011 is as follows:
			2013			2012			2011
	Balance at January 1,		$	6.2		$	—		$	—
	Additions based on tax positions of prior years			—			6.2			—
	Balance at December 31,		$	6.2		$	6.2		$	—
	These liabilities are included as a component of other liabilities in the Company’s consolidated balance sheet. The Company does not anticipate that settlement of the liabilities will require payment of cash within the next 12 months. As of December 31, 2013, $0.7 of net unrecognized tax benefit, if recognized in future periods, would impact the Company’s effective rate.
	The Company recognizes interest expense related to unrecognized tax benefits in tax expense. During the tax year ended December 31, 2013, the Company recognized approximately $0.2 of such interest expense as a component of our “Provision for Income Taxes”. During the tax year ended December 31, 2012, the Company recognized approximately $0.1 of such interest expense as a component of our “Provision for Income Taxes”.
	The Company did not recognize any interest expense related to unrecognized benefits for the year ended December 31, 2011. The Company had approximately $1.8 and $1.7 of accrued interest and $0.3 and $0.3 of accrued penalties in the Company’s balance sheet as of December 31, 2013 and 2012, respectively. The Company did not have any accrued liabilities or expense for interest or penalties related to unrecognized benefits for the year ended December 31, 2011.
	ADS Waste Holdings, Inc. and Subsidiaries
	Notes to Consolidated Financial Statements
	(In millions of dollars)
	The Company and its subsidiaries are subject to income tax in the United States at the federal, state and local jurisdictional levels. ADS and IWS are not currently under audit by the IRS. ADS has open tax years that cover the periods from 2011 through 2013. IWS recently finalized its 2011 audit with no change reported. IWS has open tax years that cover the periods from 1998 through 2010 and the tax period ending September 19, 2012. During 2013, we settled tax audits with the states of Florida and Mississippi, which resulted in tax expense of $0.1 net of federal benefit.
	On November 20, 2012, the Company acquired Veolia ES Solid Waste, Inc. in a stock acquisition. Prior to the acquisition, Veolia ES Solid Waste division was part of a consolidated group and is still subject to IRS and state examinations dating back to 2004. Pursuant to the terms of the acquisition of Veolia ES Solid Waste, Inc., the Company is entitled to certain indemnifications for Veolia ES Solid Waste Division’s pre-acquisition tax liabilities.
On September 13, 2013, the US Treasury Department and the Internal Revenue Service issued final regulations regarding the deduction and capitalization of expenditures related to tangible property. The final regulations under Internal Revenue Code Section 162, 167, and 263(a) apply to amounts paid to acquire, produce, or improve tangible property as well as dispositions of such property and are generally effective for tax years beginning on or after January 1, 2014. We have evaluated these regulations and determined they will not have a material impact on our consolidated results of operations, cash flows, or financial position.

Fair Value Disclosures [Abstract]	'
Fair Value of Financial Instruments	'
	19	Fair Value of Financial Instruments
	As a basis for considering assumptions, the fair value guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:
	Level 1		Observable inputs such as quoted prices in active markets;
	Level 2		Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and
	Level 3		Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.
	Assets and liabilities measured at fair value are based on one or more of three valuation techniques noted in the guidance. The three valuation techniques are as follows:
	Market approach
	Prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities;
	Cost approach
	Amount that would be required to replace the service capacity of an asset (i.e., replacement cost); and;
	Income approach
	Techniques to convert future amounts to a single present amount are based on market expectations (including present value techniques, option-pricing models, and lattice models).
	The Company’s financial assets and liabilities recorded at fair value on a recurring basis include derivative instruments and certain investments included in cash equivalent money market funds as restricted cash. The Company’s derivative instruments are pay-fixed, receive-variable interest rate swaps and pay-fixed, receive-variable diesel fuel commodity hedge and received-variable interest rate call option. The Company’s interest rate caps, swaps, fuel and natural gas commodity hedges and interest rate call options are recorded at their estimated fair values based on quotes received from financial institutions that trade these contracts and a current forward fixed price swap curve, respectively. The Company verifies the reasonableness of these quotes using similar quotes from another financial institution as of each date for which financial statements are prepared. For the Company’s interest rate and commodity hedges, the Company also considers the counterparty’s credit worthiness in its determination of the fair value measurement of these instruments in a net liability position. The Company’s cash equivalent money market funds are valued at quoted market prices in active markets for identical assets, which the Company receives from the financial institutions that hold such investments on its behalf. The Company’s restricted cash measured at fair value is invested primarily in U.S. government and agency securities.
	All instruments were valued using the market approach. Our interest rate caps are valued using a third-party pricing model that incorporates information about LIBOR yield curves, which is considered observable market data, for each instrument’s respective term. Counterparties to our interest rate caps are financial institutions who participate in our term B loan. Valuations of our interest rate caps may fluctuate significantly from period to period due to volatility in valuation interest rates which are driven by market conditions and the scheduled maturities of the caps. The Company’s assets and liabilities that are measured at fair value on a recurring basis approximate the following:

	Municipal solid waste service and other service contracts, permits and licenses to operate transfer stations, landfills and recycling facilities may require performance or surety bonds, letters of credit or other means of financial assurance to secure contractual performance. To secure its obligations, the Company has provided customers, various regulatory authorities and the Company’s insurer with such bonds and letters of credit totaling to approximately $690.1 and $644.3 as of December 31, 2013 and 2012, respectively. The majority of these obligations expire each year and are automatically renewed.
	In February 2009, the Company and certain of its subsidiaries were named as defendants in a purported class action suit in Circuit Court of Macon County, Alabama. Similar class action complaints were brought against the Company and certain of its subsidiaries in 2011 in Duval County, Florida and in 2013 in Quitman County, Georgia and Barbour County, Alabama. The plaintiffs in those cases primarily allege that the defendants charged improper fees (fuel, administrative and environmental fees) that were in breach of the plaintiff’s contract with the Company and seek damages in an unspecified amount. The Company believes that it has meritorious defenses against these class actions, which it will vigorously pursue. Given the inherent uncertainties of litigation, including the early stage of these cases, the unknown size of any potential class, and legal and factual issues in dispute, the outcome of these cases cannot be predicted and a range of loss if any cannot currently be estimated.
	The Company is involved in other legal proceedings and regulatory investigations from time to time in the ordinary course of business. Management believes that none of these other legal proceedings or regulatory investigations will have a material adverse effect on our financial condition, results of operations or cash flows.
	The Company is subject to various other proceedings, lawsuits, disputes and claims arising in the ordinary course of its business. Many of these actions raise complex factual and legal issues and are subject to uncertainties. Actions filed against the Company include commercial, customer, and employment-related claims, including purported class action lawsuits related to its sales and marketing practices and its customer service agreements and purported class actions involving federal and state wage and hour and other laws. The plaintiffs in some actions seek unspecified damages or injunctive relief, or both. These actions are in various procedural stages, and some are covered in part by insurance. The Company currently does not believe that the eventual outcome of any such actions could have a material adverse effect on the Company’s business, financial condition, results of operations, or cash flows.
	The Company has an obligation as part of the purchase of one of its C&D landfills for payments of 6% of net revenue that began at the commencement of landfill operations and continues through the life of the landfill.

	In September 2012, we announced a reorganization of our operations, designed to consolidate management and staff in connection with the merging of IWS and ADS. Subsequent to the closing of Veolia ES Solid Waste division, further organizational changes were announced and implemented. Principal changes included consolidation and elimination of management, relocation of staff to new regional headquarter’s locations and divesting of certain locations. Through this reorganization we eliminated approximately 88 positions throughout the Company and offered voluntary separation agreements to those impacted. For the year ended December 31, 2013, we recognized approximately $2.5 of severance costs, $1.7 for lease termination costs and $2.3 for relocation costs in the Midwest region; $0.6 for lease termination costs in the East region; $0.3 for lease termination costs in the South region and $0.3 for other expenses, as well as $2.3 of severance costs for Corporate. For the year ended December 31, 2012, we recognized employee severance and benefits restructuring charges of approximately $7.4, of which $4.3 related to the East region and the remaining amount in the Midwest region. The asset impairments were the result of the decision to consolidate locations in connection with relocation of corporate and regional offices and the decision to close certain landfills and divest assets. Other expenses are primarily for lease termination costs for exiting facilities of $2.3 associated with accomplishing the restructuring actions in the East region.
	Through December 31, 2013, the Company has recognized $19.9 of restructuring charges, of which $12.8 was related to employee severance and relocation costs and $4.0 was related to lease termination costs for exiting facilities.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Basis of Presentation	'
	Basis of Presentation
	The Company’s consolidated financial statements include its wholly-owned subsidiaries of Advanced Disposal Services South, Inc., Advanced Disposal Services East, Inc. and Veolia ES Solid Waste division and their respective subsidiaries.
	As required by accounting principles generally accepted in the United States of America for common control transactions, all assets and liabilities transferred to us as part of the Reorganization were recorded in the financial statements at carryover basis. For periods prior to the Reorganization, the combined consolidated financial statements and related notes reflect the Reorganization as if it had occurred in 2006, the date that ADStar Waste Holdings, Corp came under common control of Highstar Capital, L.P.
	For periods subsequent to the Reorganization, our consolidated financial statements include accounts and those of our majority-owned subsidiaries in which we have a controlling interest, after the elimination of intercompany accounts and transactions. All significant intercompany accounts and transactions have been eliminated in consolidation. The acquisition of the Veolia ES Solid Waste Division was accounted for as a purchase transaction and recorded at fair market value in accordance with current accounting guidance.
Noncontrolling Interests	'
	Noncontrolling Interests
	In December 2007, the FASB issued authoritative guidance that established accounting and reporting standards for noncontrolling interests in subsidiaries and for the de-consolidation of a subsidiary. The guidance also established that a noncontrolling interest in a subsidiary is an ownership interest in the consolidated entity that should be reported as equity in the consolidated financial statements. The Company owned 99.277% of HW Star Holdings Corp. as of December 31, 2012 and purchased the remaining interest in August 2013. As such, the Company has consolidated the results of the operations.
Use of Estimates	'
	Use of Estimates
	In preparing our financial statements that conform with accounting principles generally accepted in the United States of America, management uses estimates and assumptions that affect the amounts reported in these financial statements and accompanying notes. 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 from data available or simply cannot be readily calculated based on generally accepted methodologies. In preparing our financial statements, the more critical and subjective areas that deal with the greatest amount of uncertainty relate to our accounting for our long-lived assets, including recoverability, landfill development costs, and final capping, closure and post-closure costs, our valuation allowances for accounts receivable and deferred tax assets, our liabilities for potential litigation, claims and assessments, our liabilities for environmental remediation, stock compensation, accounting for goodwill and intangible asset impairments, deferred taxes, uncertain tax positions, self-insurance reserves, and our estimates of the fair values of assets acquired and liabilities assumed in any acquisition. Each of these items is discussed in more detail elsewhere in these Notes to the Consolidated Financial Statements. Our actual results may differ significantly from our estimates.
Cash and Cash Equivalents	'
	Cash and Cash Equivalents
	Cash equivalents include highly liquid investments with original maturities of three months or less when purchased.
Restricted Cash	'
	Restricted Cash
	Restricted cash consists of amounts held for landfill closure and post-closure financial assurance. The balances will fluctuate based on changes in statutory requirements, future deposits made to comply with contractual arrangements, ongoing use of funds for qualifying events or the acquisitions or divestitures of landfills.
Parts and Supplies Inventory	'
	Parts and Supplies Inventory
	Parts and supplies consist primarily of spare parts, fuel, tires, lubricants and processed recycled materials. Parts and supplies are stated at the lower of cost or market value utilizing an average cost method and are included in prepaid expenses and other current assets in the accompanying consolidated balance sheets.
Revenue Recognition	'
	Revenue Recognition
	The Company recognizes revenues as the services are provided. Revenue is recognized as waste is collected, as tons are received at the landfill or transfer stations, as recycled commodities are delivered to a customer, or as services are rendered to customers. Certain customers are billed and pay in advance and, accordingly, recognition of the related revenues is deferred until the services are provided. Revenues are reported net of applicable state landfill taxes. No customer represented more than 5% of revenues for the years ended December 31, 2013, 2012 or 2011.
Trade Receivables	'
	Trade Receivables
	The Company records trade receivables when billed or when services are performed, as they represent claims against third parties that will generally be settled in cash. The carrying value of our receivables, net of the allowance for doubtful accounts, represents the estimated net realizable value. We estimate losses for uncollectible accounts based on an evaluation of the aged accounts receivable and the likelihood of collection of the receivable based on historical collection data and existing economic conditions. If events or changes in circumstances indicate that specific receivable balances may be impaired, further consideration is given to the collectability of those balances.
Insurance Reserves	'
	Insurance Reserves
	The Company uses a combination of insurance with high deductibles and self-insurance for various risks including workers compensation, vehicle liability, general liability and employee group health claims. The exposure for unpaid claims and associated expenses, including incurred but not reported losses, is estimated by factoring in pending claims and historical trends data and other actuarial assumptions. In estimating our claims liability, we analyze our historical trends, including loss development and apply appropriate loss development factors to the incurred costs associated with the claims. The discounted estimated liability associated with settling unpaid claims is included in accrued expenses and other long-term liabilities in the consolidated balance sheets.
Concentrations of Credit Risk	'
	Concentrations of Credit Risk
	Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, accounts receivable and derivative instruments. The Company maintains cash and cash equivalents with banks that at times exceed applicable insurance limits. The Company reduces its exposure to credit risk by maintaining such deposits with high quality financial institutions. The Company has not experienced any losses in such accounts.
	The Company generally does not require collateral on its trade receivables. Credit risk on accounts receivable is minimized as a result of the large and diverse nature of the Company’s customer base and its ability to discontinue service, to the extent allowable, to non-paying customers. No single customer represented greater than 5% of total accounts receivable at December 31, 2013 and 2012, respectively.
Asset Impairments	'
	Asset Impairments
	The Company monitors the carrying value of our long-lived assets for potential impairment and test the recoverability of such assets whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. These events or changes in circumstances, including management decisions pertaining to such assets, are referred to as impairment indicators. Typical indicators that an asset may be impaired include (i) a significant adverse change in legal factors in the business climate, (ii) an adverse action or assessment by a regulator, and (iii) a significant adverse change in the extent or manner in which a long-lived asset is being utilized or in its physical condition. 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. If cash flows cannot be separately and independently identified for a single asset, we will determine whether an impairment has occurred for the asset group for which we can identify the projected cash flows. 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. Fair value is generally determined by considering (i) internally developed discounted projected cash flow analysis of the asset or asset group; (ii) third-party valuations; and/or (iii) information available regarding the current market for similar assets. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying value exceeds the fair value of the asset.
Property and Equipment, Net	'
	Property and Equipment, Net
	Property and equipment are recorded at cost, less accumulated depreciation. Expenditures for major additions and improvements are capitalized and maintenance activities are expensed as incurred. When property and equipment are retired, sold, or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts, and any resulting gain or loss is included in the results of operations. Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Assets to be disposed of are reported at the lower of the carrying amount or fair value less cost to sell. Depreciation expense is calculated using the straight-line method over the estimated useful lives or the lease term, whichever is shorter. Estimated useful lives are as follows:
			Years
	Vehicles			5–10
	Machinery and equipment			3–10
	Containers			5–15
	Furniture and fixtures			5–7
	Building and improvements			5–39
Leases	'
	Leases
	We lease property and equipment in the ordinary course of our business. Our most significant lease obligations are for property and equipment specific to our industry, including real property operated as landfills and transfer stations. Our leases have varying terms. Some may include renewal or purchase options, escalation clauses, restrictions, penalties or other obligations that we consider in determining minimum lease payments. The leases are classified as either operating leases or capital leases, as appropriate.
	The majority of our leases are operating leases. This classification generally can be attributed to either (i) relatively low fixed minimum lease payments as a result of real property lease obligations that vary based on the volume of waste we receive or process or (ii) minimum lease terms that are much shorter than the assets’ economic useful lives. Management expects that in the normal course of business our operating leases will be renewed, replaced by other leases, or replaced with fixed asset expenditures. Our rent expense during each of the last three years and our future minimum operating lease payments for each of the next five years for which we are contractually obligated as of December 31, 2013 are disclosed in Note 14.
	Assets under capital leases are capitalized using interest rates determined at the inception of each lease and are amortized over either the useful life of the asset or the lease term, as appropriate, on a straight-line basis. The present value of the related lease payments is recorded as a debt obligation.
	From an operating perspective, landfills that are leased are similar to landfills we own because generally we own the landfill’s operating permit and will operate the landfill for the entire lease term, which in many cases is the life of the landfill. As a result, our landfill leases are generally capital leases. For landfill capital leases that provide for minimum contractual rental obligations, we record the present value of the minimum obligation as part of the landfill asset, which is amortized on a units-of-consumption basis over the shorter of the lease term or the life of the landfill. The one leased landfill was sold in fiscal 2013 (Note 4).
Landfill Accounting	'
	Landfill Accounting
	Costs Basis of Landfill Assets — Landfills are typically developed in a series of cells, each of which is constructed, filled and capped in sequence over the operating life of the landfill. When the final cell is filled and the operating life of the landfill is completed, the cell must be capped and then closed and post-closure care and monitoring activities begin. Capitalized landfill costs include expenditures for land (which includes the land of the landfill footprint and landfill buffer property and setbacks) and related airspace associated with the permitting, development and construction of new landfills, expansions at existing landfills, landfill gas systems and landfill cell development. Landfill permitting, development and construction costs represent direct costs related to these activities, including land acquisition, engineering, legal and construction. These costs are deferred until all permits are obtained and operations have commenced at which point they are capitalized and amortized. If necessary permits are not obtained, costs are charged to operations. The cost basis of our landfill assets also includes asset retirement costs, which represent estimates of future costs associated with landfill final capping, closure and post-closure activities.
	Final Capping, Closure and Post-Closure Costs — The following is a description of our asset retirement activities and related accounting:
	Final Capping — Includes installing flexible membrane and geosynthetic clay liners, drainage and compact soil layers, and topsoil, and is constructed over an area of the landfill where total airspace capacity has been consumed and waste disposal operations have ceased. These final capping activities occur in phases as needed throughout the operating life of a landfill as specific areas are filled to capacity and the final elevation for that specific area is reached in accordance with the provisions of the operating permit. Final capping asset retirement obligations are recorded on a units-of-consumption basis as airspace is consumed related to the specific final capping event with a corresponding increase in the landfill asset. Each final capping event is accounted for as a discrete obligation and recorded as an asset and a liability based on estimates of the discounted cash flows and capacity associated with each final capping event.
	Closure and post-closure — These activities involve methane gas control, leachate management and groundwater monitoring, surface water monitoring and control, and other operational and maintenance activities that occur after the site ceases to accept waste. The post-closure period generally runs for 30 years after final site closure for landfills. Landfill costs related to closure and post-closure are recorded as an asset retirement obligation as airspace is consumed over the life of the landfill with a corresponding increase in the landfill asset. Obligations are recorded over the life of the landfill based on estimates of the discounted cash flows associated with performing the closure and post-closure activities.
	The Company updates annually its estimates for these obligations considering the respective State regulatory requirements, input from our internal engineers, operations, and accounting personnel and external consulting engineers. The closure and post-closure requirements are established under the standards of the U.S. Environmental Protection Agency’s Subtitle D regulations as implemented and applied on a state-by-state basis. These estimates involve projections of costs that will be incurred as portions of the landfill are closed and during the post-closure monitoring period.
	Capping, closure and post-closure costs are estimated assuming such costs would be incurred by a third party contractor in present day dollars and are inflated by the 20-year average change in the historical Consumer Price Index (consistent historical rate which agrees to historical CPI per government website of 2.50% from 1991 to 2012) to the time periods within which it is estimated the capping, closure and post-closure costs will be expended. We discount these costs to present value using the credit-adjusted, risk-free rate effective at the time an obligation is incurred, consistent with the expected cash flow approach. Any change that results in an upward revision to the estimated cash flows are treated as a new liability and discounted at the current rate while downward revisions are discounted at the historical weighted-average rate of the recorded obligation. As a result, the credit-adjusted, risk-free discount rate used to calculate the present value of an obligation is specific to each individual asset retirement obligation. The weighted-average rate applicable to our asset retirement obligations at December 31, 2013 is between 6.9% and 10.5%.
	The Company records the estimated fair value of the final capping, closure and post-closure liabilities for its landfills based on the capacity consumed in the current period. The fair value of the final capping obligations is developed based on the Company’s estimates of the airspace consumed to date for each final capping event and the expected timing of each final capping event. The fair value of closure and post-closure obligations is developed based on the Company’s estimates of the airspace consumed to date for the entire landfill and the expected timing of each closure and post-closure activity. Because these obligations are measured at estimated fair value using present value techniques, changes in the estimated cost or timing of future final capping, closure and post-closure activities could result in a material change in these liabilities, related assets and results of operations. The Company assesses the appropriateness of the estimates used to develop our recorded balances annually, or more often if significant facts change.
	Changes in inflation rates or the estimated costs, timing or extent of future final capping, closure and post-closure activities typically result in both (i) a current adjustment to the recorded liability and landfill asset; and (ii) a change in liability and asset amounts to be recorded prospectively over either the remaining capacity of the related discrete final capping event or the remaining permitted and expansion airspace (as defined below) of the landfill. Any changes related to the capitalized and future cost of the landfill assets are then recognized in accordance with our amortization policy, which would generally result in amortization expense being recognized prospectively over the remaining capacity of the final capping event or the remaining permitted and expansion airspace of the landfill, as appropriate. Changes in such estimates associated with airspace that has been fully utilized result in an adjustment to the recorded liability and landfill assets with an immediate corresponding adjustment to landfill airspace amortization expense.
	Interest accretion on final capping, closure and post-closure liabilities is recorded using the effective interest method and is recorded in operating expenses in the consolidated statements of operations.
	Amortization of Landfill Assets — The amortizable basis of a landfill includes (i) amounts previously expended and capitalized; (ii) capitalized and projected landfill final capping, closure and post-closure costs; (iii) projections of future acquisition and development costs required to develop the landfill site to its remaining permitted and expansion capacity; and (iv) land underlying both the footprint of the landfill and the surrounding required setbacks and buffer land.
	Amortization is recorded on a units-of-consumption basis, applying expense as a rate per ton. The rate per ton is calculated by dividing each component of the amortizable basis of a landfill by the number of tons needed to fill the corresponding asset’s airspace. For landfills that we do not own, but operate through operating or lease arrangements, the rate per ton is calculated based on expected capacity to be utilized over the lesser of the contractual term of the underlying agreement or the life of the landfill.
	Landfill site costs are depleted to zero upon final closure of a landfill. The Company develops our estimates of the obligations using input from our operations personnel, engineers and accountants and the obligations are based upon interpretation of current requirements and proposed regulatory changes and intended to approximate fair value. The estimate of fair value is based upon present value techniques using historical experience and, where available, quoted or actual market prices paid for similar work.
	The determination of airspace usage and remaining airspace is an essential component in the calculation of landfill asset depletion. This estimation is performed by conducting periodic topographic surveys, using aerial survey techniques, of the Company’s landfill facilities to determine remaining airspace in each landfill. The surveys are reviewed by the Company’s external consulting engineers, internal operating staff, and its management, financial and accounting staff.
	Remaining airspace will include additional “deemed permitted” or unpermitted expansion airspace if the following criteria are met:
		-1	The Company must either own the property for the expansion or have a legal right to use or obtain property to be included in the expansion plan;
		-2	Conceptual design of the expansion must have been completed;
		-3	Personnel are actively working to obtain land use and local and state approvals for an expansion of an existing landfill and the application for expansion must reasonably be expected to be received within the normal application and processing time periods for approvals in the jurisdiction in which the landfill is located;
		-4	There are no known significant technical, community, business, or political restrictions or similar issues that would likely impair the success of the expansion;
		-5	Financial analysis has been completed and the results demonstrate that the expansion has a positive financial and operational impact.
	Senior management must have reviewed and approved all of the above. Of our 42 active landfills, nine include deemed permitted airspace at December 31, 2013.
	Upon successful meeting of the preceding criteria, the costs associated with developing, constructing, closing and monitoring the total additional future capacity are considered in the calculation of the amortization and closure and post-closure rates.
	Once expansion airspace meets these criteria for inclusion in the Company’s calculation of total available disposal capacity, management continuously monitors each site’s progress in obtaining the expansion permit. If at any point it is determined that an expansion area no longer meets the required criteria, the deemed expansion airspace is removed from the landfill’s total available capacity, and the rates used at the landfill to amortize costs to acquire, construct, close and monitor the site during the post-closure period are adjusted prospectively. In addition, any amounts related to the probable expansion are charged to expense in the period in which it is determined that the criteria are no longer met.
	Once the remaining permitted and expansion airspace is determined in cubic yards, an airspace utilization factor (“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 and is then adjusted to account for future settlement. The amount of settlement that is forecasted will take into account several site-specific factors including: current and projected mix of waste type, initial and projected waste density, estimated number of years of life remaining, depth of underlying waste, anticipated access to moisture through precipitation or recirculation of landfill leachate and operating practices. In addition, the initial selection of the AUF is subject to a subsequent multi-level review by our engineering group, and the AUF used is reviewed on a periodic basis and revised as necessary. Our historical experience generally indicates that the impact of settlement at a landfill is greater later in the life of the landfill when the waste placed at the landfill approaches its highest point under the permit requirements.
	After determining the costs and 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 each landfill for assets associated with each final capping event, for assets related to closure and post-closure activities and for all other costs capitalized or to be capitalized in the future. These rates per ton are updated annually, or more often, as significant facts change.
	It is possible that the Company’s estimates or assumptions could ultimately be significantly different from actual results. In some cases the Company may be unsuccessful in obtaining an expansion permit or the Company may determine that an expansion permit that the Company previously thought was probable has become unlikely. To the extent that such estimates, or the assumptions used to make those estimates, prove to be significantly different than actual results, or the belief that the Company will receive an expansion permit changes adversely in a significant manner, the costs of the landfill, including the costs incurred in the pursuit of the expansion, may be subject to impairment testing and lower profitability may be experienced due to higher amortization rates, higher capping, closure and post-closure rates, and higher expenses or asset impairments related to the removal of previously included expansion airspace.
	The assessment of impairment indicators and the recoverability of our capitalized costs associated with landfills and related expansion projects require significant judgment due to the unique nature of the waste industry, the highly regulated permitting process and the estimates involved. During the review of a landfill expansion application, a regulator may initially deny the expansion application although the permit is ultimately granted. In addition, management may periodically divert waste from one landfill to another to conserve remaining permitted landfill airspace, or a landfill may be required to cease accepting waste, prior to receipt of the expansion permit. However, such events occur in the ordinary course of business in the waste industry and do not necessarily result in an impairment of our landfill assets because, after consideration of all facts, such events may not affect our belief that we will ultimately obtain the expansion permit. As a result, our tests of recoverability, which generally make use of a cash flow estimation approach, may indicate that an impairment loss should be recorded. No landfill impairments were recorded for the year ended December 31, 2013. At December 31, 2012, one of our landfill sites was deemed to be impaired due to permitting issues and we recorded an impairment charge of approximately $43.7 for the year ended December 31, 2012 in the East region. We performed tests of recoverability for this landfill and the carrying value exceeded the undiscounted cash flows.
Capitalized Interest	'
	Capitalized Interest
	The Company capitalizes interest on certain projects under development, including landfill construction projects. For the years ending December 31, 2013, 2012 and 2011, total interest cost was $163.7, $49.7 and $25.3, respectively, of which $0.6, $0.3 and $0.8 was capitalized.
Derivative Financial Instruments	'
	Derivative Financial Instruments
	The Company uses interest rate caps, swaps and call options to manage interest rate risk on its variable rate debt. The Company uses commodity derivatives to reduce the exposure of changes in diesel fuel and natural gas prices. The instruments qualifying for hedge accounting treatment have been designated as cash flow hedges for accounting purposes with changes in fair value, to the extent effective, recognized in accumulated other comprehensive income within the equity section of the consolidated balance sheets. Amounts are reclassified into earnings when the forecasted transaction affects earnings for the commodity derivatives. Any ineffectiveness for those instruments that do not qualify for hedge accounting, the amount of ineffectiveness or change in market value, respectively is recognized into earnings immediately without offset. The fair values of the derivatives are included in other current or long-term assets or other current or long term liabilities as appropriate. The Company obtains current valuations of its interest rate, fuel and natural gas hedging instruments from over-the-counter market quotes to determine the fair value of the outstanding derivatives.
Debt Issuance Costs	'
	Debt Issuance Costs
	The costs related to the issuance of debt are capitalized and amortized to interest expense using either the straight-line method over the life of the related debt, which approximates the effective interest method or the effective interest method.
	During fiscal 2013, the Company refinanced its Term B Loan and the transaction was accounted for as a modification of debt. The total amount of debt costs capitalized for the year ended December 31, 2013 was approximately $22.9 and there were no debt issuance costs written off for the year ended December 31, 2013. For the year ended December 31, 2012, the Company wrote-off approximately $9.4 of debt issuance costs related to the extinguishment of its revolving lines of credit and term loans, which was accomplished through an issuance of senior notes and refinancing of its revolving lines of credit and term loans in connection with the acquisition of Veolia ES Solid Waste division. For the year ended December 31, 2011, the Company wrote-off approximately $4.8 of debt issuance costs related to the extinguishment of outstanding Term Loan B, amendments to the credit facilities, refinancing of certain note obligations and revolving credit facilities. These transactions were accounted for as extinguishments and these charges are included in debt conversion costs and early extinguishment of debt in the consolidated statements of operations.
	Debt issuance costs are amortized to interest expense during the year using the straight-line method or the effective interest method. For the years ended December 31, 2013, 2012 and 2011, the Company amortized $12.6, $5.0 and $2.7, respectively, of these costs to interest expense.
Acquisitions	'
	Acquisitions
	The Company recognizes assets acquired and liabilities assumed in business combinations, including contingent assets and liabilities, based on fair values as of the date of acquisition. Any excess of purchase price over the fair value of the net assets acquired is recorded as goodwill.
	In certain acquisitions, we agree to pay additional amounts to sellers contingent upon achievement by the acquired businesses of certain negotiated goals, such as targeted revenue levels, targeted disposal volumes or the issuance of permits for expanded landfill airspace. We have recognized liabilities for these contingent obligations based on their estimated fair value at the date of acquisition with any differences between the acquisition-date fair value and the ultimate settlement of the obligations being recognized as an adjustment to income from operations.
	Assets and liabilities arising from contingencies such as pre-acquisition environmental matters and litigation are recognized at their acquisition-date fair value when their respective fair values can be determined. If the fair values of such contingencies cannot be determined, we report provisional amounts for which the accounting is incomplete.
	Acquisition-date fair value estimates are revised as necessary and accounted for as an adjustment to income from operations if, and when, additional information becomes available to further define and quantify assets acquired and liabilities assumed. All acquisition-related transaction costs have been expensed as incurred.
Goodwill	'
	Goodwill
	Goodwill is the excess of the Company’s purchase price over the fair value of the net identifiable assets of acquired businesses. The Company does not amortize goodwill. Goodwill is subject to at least an annual assessment for impairment by evaluating quantitative factors.
	The Company performs a quantitative assessment or two-step impairment test to determine whether a goodwill impairment exists at a reporting unit. The reporting units are equivalent to the Company’s segments and when an individual business within an integrated operating segment is divested, goodwill is allocated to that business based on its fair value relative to the fair value of its operating segment. The Company compares the fair value with its carrying amount to determine if there is potential impairment of goodwill. If the carrying value exceeds estimated fair value, there is an indication of potential impairment and the second step is performed to measure the amount of impairment. Fair value is estimated using an income approach based on forecasted cash flows. Fair value computed via this method is arrived at using a number of factors, including projected future operating results, economic projections, anticipated future cash flows and comparable marketplace data. There are inherent uncertainties related to these factors and to our judgment in applying them to this analysis. However, the Company believes that this method provides a reasonable approach to estimating the fair value of its reporting units.
	The Company performs its annual assessment as of December 31 of each year. The impairment test indicated the fair value of each reporting unit exceeded the carrying value. If we do not achieve our anticipated disposal volumes, our collection or disposal rates decline, our costs or capital expenditures exceed our forecasts, costs of capital increase, or we do not receive landfill expansions, the estimated fair value could decrease and potentially result in an impairment charge in the future. Refer to Note 4 for information regarding impairment charges recorded in connection with discontinued operations. The Company recorded no goodwill impairment charges for the years ended December 31, 2013, 2012 and 2011, respectively.
Intangible Assets, Net	'
	Intangible Assets, Net
	Intangible assets are stated at cost less accumulated amortization and consist of noncompete agreements, tradenames, customer contracts and customer lists and are amortized over their estimated useful lives. The carrying values of intangibles are periodically reviewed by management to determine if the facts and circumstances suggest that they may be impaired. If the carrying value exceeds estimated fair value, an impairment charge would be recognized in the amount of the excess. Fair value is typically estimated using an income approach for the respective asset, as described above. The Company recorded an impairment charge of $0.6 for the year ended December 31, 2013 related to discontinuance of a trade name. No such impairments have been identified for the years ended December 31, 2012 and 2011, respectively in connection with ongoing operations. Refer to Note 4 for information regarding impairment charges recorded in connection with discontinued operations.
Income Taxes	'
	Income Taxes
	The Company is subject to income tax in the United States. Current tax obligations associated with the provision for income taxes are reflected in the accompanying consolidated balance sheets as a component of accrued expenses and the deferred tax obligations are reflected in deferred income tax asset or liability. Deferred income taxes arise from temporary differences resulting from income and expense items reported for financial accounting and tax purposes in different periods. Deferred income taxes are classified as current or noncurrent, depending on the classification of the assets and liabilities to which they relate. Deferred income taxes arising from temporary differences that are not related to an asset or liability are classified as current or noncurrent depending on the periods in which the temporary differences are expected to reverse. Significant judgment is required in assessing the timing and amounts of deductible and taxable items. We establish reserves for uncertain tax positions, when despite our belief that our tax return positions are fully supportable, we believe that certain positions may be challenged and potentially disallowed. When facts and circumstances change, we adjust these reserves through our provision for income taxes. To the extent interest and penalties may be assessed by taxing authorities on any underpayment of income tax, such amounts have been accrued and are classified as a component of tax expense in our consolidated statements of operations.
Contingencies	'
	Contingencies
	We are subject to various legal proceedings, claims and regulatory matters, the outcomes of which are subject to significant uncertainty. In general, 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 assess our potential liability relating to litigation and regulatory matters based on information available to us. Management develops its assessment 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 disclose the potential range of the loss, if estimable. (Note 20)
New Accounting Standards	'
	New Accounting Standards
	In June 2011, the FASB issued ASU No. 2011-05, “Presentation of Comprehensive Income” (“ASU No. 2011-05”) to require other comprehensive income, including reclassification adjustments, to be presented with net income in one continuous statement or in a separate statement consecutively following the Consolidated Statement of Income. In December 2011, the FASB issued update ASC No. 2011-12, “Comprehensive Income: Deferral of the Effective Date for Amendments to the Presentation of Reclassifications of Items Out of Accumulated Other Comprehensive Income in Accounting Standards Update No. 2011-05” (“ASU No. 2011-12”) which requires deferral of only those changes in ASU No. 2011-05 that relate to the presentation of reclassification adjustments, and the paragraphs in this update supersede certain pending paragraphs in ASU No. 2011-05. ASU No. 2011-12 is effective for public entities for fiscal years, and interim periods within those years, beginning after December 15, 2011. For non-public entities, the amendments are effective for fiscal years ending after December 15, 2012, and interim and annual periods thereafter. The Company adopted this statement without impact on our consolidated financial statements other than in the presentation of comprehensive loss.
	In September 2011, the FASB issued ASU 2011-08, Testing Goodwill for Impairment, amending Accounting Standards Codification (“ASC”) Topic 350, Intangibles — Goodwill and Other (“ASC 350”). The amendment permits an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test already required under ASC 350. The amendment is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. Early adoption is permitted, including for annual and interim goodwill impairment tests performed as of a date before September 15, 2011, for nonpublic entities’ financial statements which have not yet been made available for issuance. The Company adopted this statement without impact on our consolidated financial statements.
	In December 2011, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2011-11, “Disclosures about Offsetting Assets and Liabilities” (“ASU No. 2011-11”) to require new disclosures about offsetting assets and liabilities to help enable users of financial statements evaluate certain significant quantitative differences in balance sheets prepared under U.S. GAAP. ASU No. 2011-11 is effective for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. The adoption did not have a material impact on the consolidated financial statements.
	In February 2013, the Financial Accounting Standards Board (“FASB”) issued amended authoritative guidance associated with comprehensive income, which requires companies to provide information about the amounts that are reclassified out of accumulated other comprehensive income by component. Additionally, companies are required to present significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income. The amendment to authoritative guidance associated with comprehensive income was effective for the Company on January 1, 2013. The adoption of this guidance did not have a material impact on our consolidated financial statements. We have presented the information required by this amendment in Note 24.
