PART I

ITEM 1. BUSINESS

Our Company

Waste Connections, Inc. is an integrated municipal solid waste, or MSW, services company that provides solid waste collection, transfer, disposal and recycling services primarily in exclusive and secondary markets in the U.S. and a leading provider of non-hazardous exploration and production, or E&P, waste treatment, recovery and disposal services in several of the most active natural resource producing areas of the U.S. We also provide intermodal services for the rail haul movement of cargo and solid waste containers in the Pacific Northwest through a network of intermodal facilities.

As of December 31, 2013, we served residential, commercial, industrial and E&P customers in 31 states:  Alabama, Alaska, Arizona, California, Colorado, Idaho, Illinois, Iowa, Kansas, Kentucky, Louisiana, Massachusetts, Michigan, Minnesota, Mississippi, Montana, Nebraska, Nevada, New Mexico, New York, North Carolina, North Dakota, Oklahoma, Oregon, South Carolina, South Dakota, Tennessee, Texas, Utah, Washington and Wyoming.  As of December 31, 2013, we owned or operated a network of 148 solid waste collection operations; 66 transfer stations; seven intermodal facilities, 36 recycling operations, 55 active MSW, E&P and/or non-MSW landfills, 20 E&P liquid waste injection wells, 17 E&P waste treatment and recovery facilities and 20 oil recovery facilities. Non-MSW landfills accept construction and demolition, industrial and other non-putrescible waste.

Our senior management team has extensive experience in operating, acquiring and integrating non-hazardous waste services businesses, and we intend to continue to focus our efforts on balancing internal and acquisition-based growth.  We anticipate that a part of our future growth will come from acquiring additional MSW and E&P waste businesses and, therefore, we expect that additional acquisitions could continue to affect period-to-period comparisons of our operating results. 

Waste Connections, Inc. is a Delaware corporation organized in 1997. 

Our Operating Strategy

Our operating strategy seeks to improve financial returns and deliver superior stockholder value creation within the solid waste industry.  We seek to avoid highly competitive, large urban markets and instead target markets where we can attain high market share either through exclusive contracts, vertical integration or asset positioning. We also target niche markets, like E&P waste treatment and disposal services, with similar characteristics and, we believe, higher comparative growth potential. We are a leading provider of waste services in most of our markets, and the key components of our operating strategy, which are tailored to the competitive and regulatory factors that affect our markets, are as follows: 

Target Secondary and Rural Markets. By targeting secondary and rural markets, we believe that we are able to garner a higher local market share than would be attainable in more competitive urban markets, which we believe reduces our exposure to customer churn and improves financial returns. In certain niche markets, like E&P waste treatment and disposal, early mover advantage in certain rural basins may improve market positioning and financial returns given the limited availability of existing third-party-owned waste disposal alternatives.

Control the Waste Stream.  In markets where waste collection services are provided under exclusive arrangements, or where waste disposal is municipally owned or funded or available at multiple sources, we believe that controlling the waste stream by providing collection services under exclusive arrangements is often more important to our growth and profitability than owning or operating landfills.  In addition, in certain E&P markets with “no pit” rules or other regulations that limit on-site storage or treatment of waste, control of the waste stream allows us to generate additional service revenue from the transportation of waste, as well as the waste treatment and disposal, thus increasing the overall scope and value of the services provided. 

Optimize Asset Positioning.  We believe that the location of disposal sites within competitive markets is a critical factor to success in both MSW and E&P waste services.  Given the importance of and costs associated with the transportation of waste to treatment and disposal sites, having disposal capacity proximate to the waste stream may provide a competitive advantage and serve as a barrier to entry.

Provide Vertically Integrated Services.  In markets where we believe that owning landfills is a strategic advantage to a collection operation because of competitive and regulatory factors, we generally focus on providing integrated services, from collection through disposal of solid waste in landfills that we own or operate. Similarly, we see this strategic advantage in E&P waste services where we offer closed loop systems for liquid and solid waste storage, transportation, treatment, and disposal.

1

Manage on a Decentralized Basis.  We manage our operations on a decentralized basis.  This places decision-making authority close to the customer, enabling us to identify and address customers’ needs quickly in a cost-effective manner.  We believe that decentralization provides a low-overhead, highly efficient operational structure that allows us to expand into geographically contiguous markets and operate in relatively small communities that larger competitors may not find attractive.  We believe that this structure gives us a strategic competitive advantage, given the relatively rural nature of many of the markets in which we operate, and makes us an attractive buyer to many potential acquisition candidates. 

As of December 31, 2013, we delivered our services from over 200 operating locations grouped into four operating segments: our Western segment is comprised of operating locations in Alaska, California, Idaho, Montana, Nevada, Oregon, Washington and western Wyoming; our Central segment is comprised of operating locations in Arizona, Colorado, Kansas, Louisiana, Minnesota, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, Utah and eastern Wyoming; our Eastern segment is comprised of operating locations in Alabama, Illinois, Iowa, Kentucky, Massachusetts, Michigan, Mississippi, New York, North Carolina, South Carolina and Tennessee; and, our E&P segment includes the majority of our E&P waste service operations in Louisiana, New Mexico, North Dakota, Oklahoma, Texas, Wyoming and along the Gulf of Mexico.  Some E&P revenues are also included in other operating segments, where we accept E&P waste at some of our solid waste landfills.

We manage and evaluate our business on the basis of the operating segments’ geographic characteristics, interstate waste flow, revenue base, employee base, regulatory structure, and acquisition opportunities.  Each operating segment has a regional vice president and a regional controller reporting directly to our corporate management.  These regional officers are responsible for operations and accounting in their operating segments and supervise their regional staff.  See Note 15 to the consolidated financial statements for further information on our segment reporting of our operations. 

Each operating location has a district or site manager who has a high degree of decision-making authority for his or her operations and is responsible for maintaining service quality, promoting safety, implementing marketing programs and overseeing day-to-day operations, including contract administration.  Local managers also help identify acquisition candidates and are responsible for integrating acquired businesses into our operations and obtaining the permits and other governmental approvals required for us to operate. 

Implement Operating Standards.  We develop company-wide operating standards, which are tailored for each of our markets based on industry norms and local conditions.  We implement cost controls and employee training and safety procedures and establish a sales and marketing plan for each market.  By internalizing the waste stream of acquired operations, we can further increase operating efficiencies and improve capital utilization.  We use a wide-area information system network, implement financial controls and consolidate certain accounting, personnel and customer service functions.  While regional and district management operate with a high degree of autonomy, our executive officers monitor regional and district operations and require adherence to our accounting, purchasing, marketing and internal control policies, particularly with respect to financial matters.  Our executive officers regularly review the performance of regional officers, district managers and operations.  We believe we can improve the profitability of existing and newly acquired operations by establishing operating standards, closely monitoring performance and streamlining certain administrative functions. 

Our Growth Strategy

We tailor the components of our growth strategy to the markets in which we operate and into which we hope to expand. 

Obtain Additional Exclusive Arrangements.  Our operations include market areas where we have exclusive arrangements, including franchise agreements, municipal contracts and governmental certificates, under which we are the exclusive service provider for a specified market.  These exclusive rights and contractual arrangements create a barrier to entry that is usually obtained through the acquisition of a company with such exclusive rights or contractual arrangements or by winning a competitive bid. 

We devote significant resources to securing additional franchise agreements and municipal contracts through competitive bidding and by acquiring other companies.  In bidding for franchises and municipal contracts and evaluating acquisition candidates holding governmental certificates, our management team draws on its experience in the waste industry and knowledge of local service areas in existing and target markets.  Our district management and sales and marketing personnel maintain relationships with local governmental officials within their service areas, maintain, renew and renegotiate existing franchise agreements and municipal contracts, and secure additional agreements and contracts while targeting acceptable financial returns.  Our sales and marketing personnel also expand our presence into areas adjacent to or contiguous with our existing markets, and market additional services to existing customers.  We believe our ability to offer comprehensive rail haul disposal services in the Pacific Northwest improves our competitive position in bidding for such contracts in that region. 

2

Generate Internal Growth.  To generate internal revenue growth, our district management and sales and marketing personnel focus on increasing market penetration in our current and adjacent markets, soliciting new customers in markets where such customers have the option to choose a particular waste collection service and marketing upgraded or additional services (such as compaction or automated collection) to existing customers.  We also seek price increases necessary to offset increased costs, to improve operating margins and to obtain adequate returns on our deployed capital.  Where possible, we intend to leverage our franchise-based platforms to expand our customer base beyond our exclusive market territories.  As customers are added in existing markets, our revenue per routed truck increases, which generally increases our collection efficiencies and profitability.  In markets in which we have exclusive contracts, franchises and governmental certificates, we expect internal volume growth generally to track population and business growth. 

In niche disposal markets, like E&P, our focus is on increasing market penetration, and providing additional service offerings in existing markets where appropriate. In addition, we focus on developing and permitting new treatment and disposal sites in new and existing E&P markets to position ourselves to capitalize on current and future drilling activity in those areas.

Expand Through Acquisitions.  We intend to expand the scope of our operations by continuing to acquire MSW and E&P waste facilities and companies in new markets and in existing or adjacent markets that are combined with or “tucked in” to our existing operations.  We focus our acquisition efforts on markets that we believe provide significant growth opportunities for a well-capitalized market entrant and where we can create economic and operational barriers to entry by new competitors.  This focus typically highlights markets in which we can:  (1) provide waste collection services under exclusive arrangements such as franchise agreements, municipal contracts and governmental certificates; (2) gain a leading market position and provide vertically integrated collection and disposal services; or (3) gain a leading market position in a niche market through the provision of treatment and disposal services.  We believe that our experienced management, decentralized operating strategy, financial strength, size, and public company status make us an attractive buyer to certain waste collection and disposal acquisition candidates.  We have developed an acquisition discipline based on a set of financial, market and management criteria to evaluate opportunities.  Once an acquisition is closed, we seek to integrate it while minimizing disruption to our ongoing operations and those of the acquired business. 

In new markets, we often use an initial acquisition as an operating base and seek to strengthen the acquired operation's presence in that market by providing additional services, adding new customers and making “tuck-in” acquisitions of other waste companies in that market or adjacent markets.  We believe that many suitable “tuck-in” acquisition opportunities exist within our current and targeted market areas that may provide us with opportunities to increase our market share and route density. 

The U.S. solid waste services industry experienced significant consolidation during the 1990s.  The consolidation trend has continued, most notably with the merger between Republic Services, Inc. and Allied Waste Industries, Inc. in 2008, the merger between IESI-BFC Ltd. and Waste Services, Inc. in 2010, and the sale of the U.S. solid waste business of Veolia Environnement S.A. to Advanced Disposal Services, Inc. in 2012. In spite of this consolidation, the solid waste services industry remains regional in nature, with acquisition opportunities available in select markets.  The E&P waste services industry is similarly regional in nature and is also highly fragmented, with acquisition opportunities available in several active natural resource basins. In some markets in both MSW and E&P waste, independent landfill, collection or service providers lack the capital resources, management skills and/or technical expertise necessary to comply with stringent environmental and other governmental regulations and to compete with larger, more efficient, integrated operators.  In addition, many of the remaining independent operators may wish to sell their businesses to achieve liquidity in their personal finances or as part of their estate planning. 

During the year ended December 31, 2013, we completed eight acquisitions, none of which individually accounted for greater than 10% of our total assets. The total fair value of consideration transferred for the eight acquisitions completed during the year ended December 31, 2013 was approximately $64.2 million. During 2012, we acquired the business of R360 Environmental Solutions, Inc., or R360, a leading provider of non-hazardous E&P waste treatment, recovery and disposal services, for total fair value of consideration transferred of $1.38 billion.  During the year ended December 31, 2012, we completed 12 other acquisitions, none of which individually or in the aggregate accounted for greater than 10% of our total assets. The total fair value of consideration transferred for the 12 other acquisitions completed during the year ended December 31, 2012 was approximately $275.8 million. During the year ended December 31, 2011, we completed 13 acquisitions, none of which individually accounted for greater than 10% of our total assets. The total fair value of consideration transferred for the 13 acquisitions completed during the year ended December 31, 2011 was approximately $375.7 million.

WASTE SERVICES

Collection Services

We provide collection services to residential, commercial, industrial and E&P customers.  Our services are generally provided under one of the following arrangements:  (1) governmental certificates; (2) exclusive franchise agreements; (3) exclusive municipal contracts; (4) residential subscriptions; (5) residential contracts; or (6) commercial, industrial and E&P service agreements. 

Governmental certificates, exclusive franchise agreements and exclusive municipal contracts grant us rights to provide MSW services within specified areas at established rates and are long-term in nature.  Governmental certificates, or G Certificates, are unique to the State of Washington and are awarded by the Washington Utilities and Transportation Commission, or WUTC, to solid waste collection service providers in unincorporated areas and electing municipalities.  These certificates typically grant the holder the exclusive and perpetual right to provide specific residential, commercial and/or industrial waste services in a defined territory at specified rates subject to divestiture and/or cancellation by the WUTC on specified, limited grounds.  Franchise agreements typically provide an exclusive period of seven years or longer for a specified territory; they specify a broad range of services to be provided, establish rates for the services and often give the service provider a right of first refusal to extend the term of the agreement.  Municipal contracts typically provide a shorter service period and a more limited scope of services than franchise agreements and generally require competitive bidding at the end of the contract term.  In markets where exclusive arrangements are not available, we may enter into residential contracts with homeowners’ associations, apartment owners and mobile home park operators, or work on a subscription basis with individual households.  In such markets, we may also provide commercial and industrial services under customer service agreements generally ranging from one to five years in duration.  Finally, in certain E&P markets with “no pit” rules or other regulations that limit on-site storage or treatment of waste, we offer containers and collection services to provide a closed loop system for the collection of drilling wastes at customers’ well sites and subsequent transportation of the waste to our facilities for treatment and disposal.

Landfill Disposal Services

As of December 31, 2013, we owned or operated 42 MSW landfills, six E&P waste landfills, which only accept E&P waste, and seven non-MSW landfills, which only accept construction and demolition, industrial and other non-putrescible waste. Thirteen of our MSW landfills also received E&P waste during 2013. We generally own landfills to achieve vertical integration in markets where the economic and regulatory environments make landfill ownership attractive.  We also own landfills in certain markets where it is not necessary to provide collection services because we believe that we are able to attract volume to our landfills, given our location or other market dynamics. Over time, MSW landfills generate a greenhouse gas, methane, which can be converted into a valuable source of clean energy. We deploy gas recovery systems at 30 of our landfills to collect methane, which can then be used to generate electricity for local households, fuel local industrial power plants, power alternative fueled vehicles, or qualify for carbon emission credits.

Our landfill facilities consisted of the following at December 31, 2013: 

Owned and operated landfills	44
Operated landfills under life-of-site agreements	6
Operated landfills under limited-term operating agreements	5
	55

Under landfill operating agreements, the owner of the property, generally a municipality, usually owns the permit and we operate the landfill for a contracted term, which may be the life of the landfill.  Where the contracted term is not the life of the landfill, the property owner is generally responsible for final capping, closure and post-closure obligations.  We are responsible for all final capping, closure and post-closure obligations at five of our six operated landfills for which we have life-of-site agreements.  Our five operating contracts for which the contracted term is less than the life of the landfill have expiration dates from 2014 to 2024, and we intend to seek renewal of these contracts prior to, or upon, their expiration.

Based on remaining permitted capacity as of December 31, 2013, and projected annual disposal volumes, the average remaining landfill life for our owned and operated landfills and landfills operated, but not owned, under life-of-site agreements, is estimated to be approximately 35 years.  Many of our existing landfills have the potential for expanded disposal capacity beyond the amount currently permitted.  We regularly consider whether it is advisable, in light of changing market conditions and/or regulatory requirements, to seek to expand or change the permitted waste streams or to seek other permit modifications.  We also monitor the available permitted in-place disposal capacity of our landfills on an ongoing basis and evaluate whether to seek capacity expansion using a variety of factors.

4

We are currently seeking to expand permitted capacity at ten of our landfills, for which we consider expansions to be probable.  Although we cannot be certain that all future expansions will be permitted as designed, the average remaining landfill life for our owned and operated landfills and landfills operated, but not owned, under life-of-site agreements is estimated to be approximately 42 years when considering remaining permitted capacity, probable expansion capacity and projected annual disposal volume. 

The following table reflects estimated landfill capacity and airspace changes, as measured in tons, for owned and operated landfills and landfills operated, but not owned, under life-of-site agreements (in thousands):

Transfer Station and Intermodal Services

As of December 31, 2013, we owned or operated 61 MSW transfer stations and five E&P waste transfer stations with marine access.  Transfer stations receive, compact and load waste to be transported to landfills or treatment facilities via truck, rail or barge.  They extend our direct-haul reach and link collection operations or waste generators with distant disposal or treatment facilities by concentrating the waste stream from a wider area and thus providing better utilization rates and operating efficiencies. 

Intermodal logistics is the movement of containers using two or more modes of transportation, usually including a rail or truck segment.  We entered the intermodal services business in the Pacific Northwest through the acquisition of Northwest Container Services, Inc., which provides repositioning, storage, maintenance and repair of cargo containers for international shipping companies.  We provide these services for containerized cargo primarily to international shipping companies importing and exporting goods through the Pacific Northwest.  We also operate two intermodal facilities primarily for the shipment of waste by rail to distant disposal facilities that we do not own.  As of December 31, 2013, we owned or operated seven intermodal operations in Washington and Oregon.  Our fleet of double-stack railcars provides dedicated direct-line haul services among terminals in Portland, Tacoma and Seattle.  We have contracts with the Burlington Northern Santa Fe and Union Pacific railroads for the movement of containers among our seven intermodal operations.  We also provide our customers container and chassis sales and leasing services. 

We intend to further expand our intermodal business through cross-selling efforts with our solid waste services operations.  We believe that a significant amount of solid waste is transported currently by truck, rail and barge from primarily the Seattle-Tacoma and Metro Portland areas to remote landfills in Eastern Washington and Eastern Oregon.  We believe our ability to market both intermodal and disposal services will enable us to more effectively compete for these volumes. 

Recycling Services

We offer residential, commercial, industrial and municipal customers recycling services for a variety of recyclable materials, including compost, cardboard, office paper, plastic containers, glass bottles and ferrous and aluminum metals. We own or operate 36 recycling processing operations and sell other collected recyclable materials to third parties for processing before resale.  The majority of the recyclables we process for sale are paper products and are shipped primarily to customers in Asia.  Changes in end market demand as well as other factors can cause fluctuations in the prices for such commodities, which can affect revenue, operating income and cash flows.  To reduce our exposure to commodity price volatility and risk with respect to recycled materials, we have adopted a pricing strategy of charging collection and processing fees for recycling volumes collected from third parties.  We believe that recycling will continue to be an important component of local and state solid waste management plans due to the public’s increasing environmental awareness and expanding regulations that mandate or encourage recycling.

E&P Waste Treatment, Recovery and Disposal Services

E&P waste is a broad term referring to the by-products resulting from oil and natural gas exploration and production activity. These generally include: waste created throughout the initial drilling and completion of an oil or natural gas well, such as drilling fluids, drill cuttings, completion fluids and flowback water; production wastes and produced water during a well’s operating life; contaminated soils that require treatment during site reclamation; and substances that require clean-up after a spill, reserve pit clean-up or pipeline rupture. E&P customers are principally integrated oil and natural gas exploration and production companies operating in the areas that we serve. E&P revenue is therefore driven by vertical and horizontal drilling, hydraulic fracturing, production and clean-up activity; it is complemented by other services including closed loop collection systems and the sale of recovered products. E&P activity varies across market areas which are tied to the natural resource basins in which the drilling activity occurs and reflects the regulatory environment, pricing and disposal alternatives available in any given market.

6

Our customers are generally responsible for the delivery of their waste streams to us. We receive flowback water, produced water and other drilling and production wastes at our facilities in vacuum trucks, dump trucks or containers deposited by roll-off trucks. In certain markets, we offer bins and rails systems that capture and separate liquid and solid oilfield waste streams at our customers’ well sites and deliver the drilling and production wastes to our facilities. Waste generated by offshore drilling is delivered by supply vessel from the drilling rig to one of our transfer stations, where the waste is then transferred to our network of barges for transport to our treatment facilities.

As of December 31, 2013, we provided E&P waste treatment, recovery and/or disposal services from a network of six E&P waste landfills, 13 MSW landfills that also received E&P waste during 2013, 20 E&P liquid waste injection wells, 17 E&P waste treatment and recovery facilities and 20 oil recovery facilities. Treatment processes vary by site and regulatory jurisdiction. At certain treatment facilities, loads of flowback and produced water and other drilling and production wastes delivered by our customers are sampled, assessed and tested by third parties according to state regulations. Solids contained in a waste load are deposited into a land treatment cell where liquids are removed from the solids and are sent through an oil recovery system before being injected into saltwater disposal injection wells or placed in evaporation cells that utilize specialized equipment to accelerate evaporation of liquids. In certain locations, fresh water is then added to the remaining solids in the cell to “wash” the solids several times to remove contaminants, including oil and grease, chlorides and other contaminants, to ensure the solids meet specific regulatory criteria that, in certain areas, are administered by third-party labs and submitted to the regulatory authorities.

After the washing or treatment process, the treated solids are designated “reuse materials,” and are no longer considered a waste product by state regulation. These materials are dried, removed from the treatment cells, stockpiled and compacted in designated stockpile areas on site and at certain locations are available for use as feedstock for roadbase. At certain of our facilities, during the treatment process we reclaim oil for resale and we treat and recycle liquids for re-use in our operations or for sale to third parties as fresh or brine water.

COMPETITION

The U.S. municipal solid waste services industry is highly competitive and requires substantial labor and capital resources.  Besides Waste Connections, the industry includes:  two national, publicly held solid waste companies – Waste Management, Inc. and Republic Services, Inc.; several regional, publicly held and privately owned companies; and several thousand small, local, privately owned companies.  Certain of the markets in which we compete or will likely compete are served by one or more large, national solid waste companies, as well as by numerous regional and local solid waste companies of varying sizes and resources, some of which we believe have accumulated substantial goodwill in their markets.  We compete for collection, transfer and disposal volume based primarily on the price and, to a lesser extent, quality of our services. We also compete with operators of alternative disposal facilities, including incinerators, and with counties, municipalities and solid waste districts that maintain their own waste collection and disposal operations.  Public sector operators may have financial and other advantages over us because of their access to user fees and similar charges, tax revenues, tax-exempt financing and the ability to flow-control waste streams to publicly owned disposal facilities. 

From time to time, competitors may reduce the price of their services in an effort to expand their market shares or service areas or to win competitively bid municipal contracts.  These practices may cause us to reduce the price of our services or, if we elect not to do so, to lose business.  We provide a significant amount of our residential, commercial and industrial collection services under exclusive franchise and municipal contracts and G Certificates. Exclusive franchises and municipal contracts may be subject to periodic competitive bidding. 

The U.S. municipal solid waste services industry has undergone significant consolidation, and we encounter competition in our efforts to acquire collection operations, transfer stations and landfills.  We generally compete for acquisition candidates with publicly owned regional and national waste management companies.  Accordingly, it may become uneconomical for us to make further acquisitions or we may be unable to locate or acquire suitable acquisition candidates at price levels and on terms and conditions that we consider appropriate, particularly in markets we do not already serve.  Competition in the disposal industry is also affected by the increasing national emphasis on recycling and other waste reduction programs, which may reduce the volume of waste deposited in landfills. 

Competition for E&P waste comes primarily from smaller regional companies that utilize a variety of disposal methods and generally serve specific geographic markets. We also compete with publicly held and privately owned companies such as Waste Management, Inc., Republic Services, Inc., Clean Harbors, Inc., Tervita Corporation, Secure Energy Services Inc. and Newpark Resources, Inc. in certain markets. In addition, customers in many markets have the option of using internal disposal methods or outsourcing to another third-party disposal company. The principal competitive factors in this business include: gaining customer approval of treatment and disposal facilities; location of facilities in relation to customer activity; reputation; reliability of services; track record of environmental compliance; ability to accept multiple waste types at a single facility; and price.

7

The intermodal services industry is also highly competitive.  We compete against other intermodal rail services companies, trucking companies and railroads, many of which have greater financial and other resources than we do.  Competition is based primarily on price, reliability and quality of service. 

REGULATION

Introduction

Our operations, including landfills, solid waste transportation, transfer stations, intermodal operations, vehicle maintenance shops, fueling facilities, and oilfield waste treatment, recovery and disposal operations, are all subject to extensive and evolving federal, state and local environmental, health, and safety laws and regulations, the enforcement of which has become increasingly stringent. These laws and regulations may, among other things, require the acquisition of permits for regulated activities; govern the amounts and types of substances that may be released into the environment in connection with our operations; restrict the way we handle or dispose of wastes; limit or prohibit our or our customers’ activities in sensitive areas such as wetlands, wilderness areas or areas inhabited by endangered or threatened species; require investigatory and remedial actions to mitigate pollution conditions caused by our operations or attributable to former operations; and impose specific standards addressing worker protections. Compliance is often costly or difficult, and the violation of these laws and regulations may result in the denial or revocation of permits, issuance of corrective action orders, assessment of administrative and civil penalties and even criminal prosecution. The environmental regulations that affect us are administered by the Environmental Protection Agency, or the EPA, and numerous other federal, state and local environmental, zoning, health and safety agencies. For example, the WUTC regulates the portion of our collection business in Washington performed under G Certificates.

We currently comply in all material respects with applicable federal, state and local environmental and occupational health and safety laws, permits, orders and regulations. In addition, we attempt to anticipate future regulatory requirements and plan in advance as necessary to comply with them. We do not presently anticipate incurring any material costs to bring our operations into environmental compliance with existing or expected future regulatory requirements, although we can give no assurance that this will not change in the future. It is possible that substantial costs for compliance or penalties for non-compliance may be incurred in the future. It is also possible that other developments, such as the adoption of stricter environmental laws, regulations and enforcement policies, could result in additional costs or liabilities that we cannot currently quantify. Moreover, changes in environmental laws could reduce the demand for our services and adversely impact our business. For example, changes in environmental laws could limit our customers’ oil and natural gas E&P businesses or encourage our customers to handle and dispose of oil and natural gas E&P wastes in other ways.

A number of the major federal, state and local statutes and regulations that apply to our operations are described generally below. Certain of the statutes described below contain provisions that authorize, under certain circumstances, lawsuits by private citizens to enforce the provisions of the statutes. In addition to penalties, some of those statutes authorize an award of attorneys' fees to parties that successfully bring such an action. Enforcement actions under these statutes may include both civil and criminal penalties, as well as injunctive relief in some instances.

The Resource Conservation and Recovery Act of 1976, or RCRA

RCRA regulates the generation, treatment, storage, handling, transportation and disposal of solid waste and requires states to develop programs to ensure the safe disposal of solid waste. RCRA divides solid waste into two groups, hazardous and nonhazardous. Wastes are generally classified as hazardous if they either: (1) are specifically included on a list of hazardous wastes; or (2) exhibit certain characteristics defined as hazardous. Household wastes are specifically designated as nonhazardous. Wastes classified as hazardous under RCRA are subject to much stricter regulation than wastes classified as nonhazardous, and businesses that deal with hazardous waste are subject to regulatory obligations in addition to those imposed on handlers of nonhazardous waste. From time to time, our intermodal services business transports hazardous materials in compliance with federal transportation requirements. Some of our ancillary operations, such as vehicle maintenance operations, may generate hazardous wastes. We manage these wastes in substantial compliance with applicable laws.

8

In October 1991, the EPA adopted the Subtitle D Regulations governing solid waste landfills. The Subtitle D Regulations, which generally became effective in October 1993, include location restrictions, facility design standards, operating criteria, closure and post-closure requirements, financial assurance requirements, groundwater monitoring requirements, groundwater remediation standards and corrective action requirements. In addition, the Subtitle D Regulations require that new landfill sites meet more stringent liner design criteria (typically, composite soil and synthetic liners or two or more synthetic liners) intended to keep leachate out of groundwater and have extensive collection systems to carry away leachate for treatment prior to disposal. Groundwater monitoring wells must also be installed at virtually all landfills to monitor groundwater quality and, indirectly, the effectiveness of the leachate collection system. The Subtitle D Regulations also require, where certain regulatory thresholds are exceeded, that facility owners or operators control emissions of methane gas generated at landfills in a manner intended to protect human health and the environment. Each state is required to revise its landfill regulations to meet these requirements or such requirements will be automatically imposed by the EPA on landfill owners and operators in that state. Each state is also required to adopt and implement a permit program or other appropriate system to ensure that landfills in the state comply with the Subtitle D Regulations. Various states in which we operate or may operate in the future have adopted regulations or programs as stringent as, or more stringent than, the Subtitle D Regulations.

Most E&P waste is exempt from stringent regulation as a hazardous waste under RCRA. None of our oilfield waste recycling, treatment, and disposal facilities are currently permitted to accept hazardous wastes for disposal, and we take precautions to help ensure that hazardous wastes do not enter or are not disposed of at these facilities. Some wastes handled by us that currently are exempt from treatment as hazardous wastes may in the future be designated as “hazardous wastes” under RCRA or other applicable statutes. For example, in September 2010, a nonprofit environmental group filed a petition with the EPA requesting reconsideration of the RCRA E&P waste exemption. Although the EPA has not yet formally responded to the petition, if the RCRA E&P waste exemption is repealed or modified, we could become subject to more rigorous and costly operating and disposal requirements.

We are required to obtain permits for the land treatment and disposal of E&P waste as part of our operations. The construction, operation and closure of E&P waste land treatment and disposal operations are generally regulated at the state level. These regulations vary widely from state to state. State permits can restrict size and location of disposal operations, impose limits on the types and amount of waste a facility may receive and the overall capacity of a waste disposal facility. States may add additional restrictions on the operations of a disposal facility when a permit is renewed or amended. As these regulations change, our permit requirements could become more stringent and may require material expenditures at our facilities or impose significant restraints or financial assurances on our operations.

In the course of our E&P waste operations, some of our equipment may be exposed to naturally occurring radiation associated with oil and gas deposits, and this exposure may result in the generation of wastes containing naturally occurring radioactive materials, or NORM. NORM wastes exhibiting trace levels of naturally occurring radiation in excess of established state standards are subject to special handling and disposal requirements, and any storage vessels, piping and work area affected by NORM may be subject to remediation or restoration requirements. It is possible that we may incur costs or liabilities associated with elevated levels of NORM.

RCRA also regulates underground storage of petroleum and other regulated materials. RCRA requires registration, compliance with technical standards for tanks, release detection and reporting, and corrective action, among other things. Certain of our facilities and operations are subject to these requirements.

The Federal Water Pollution Control Act of 1972, or the Clean Water Act

The Clean Water Act regulates the discharge of pollutants from a variety of sources, including solid waste disposal sites, transfer stations, and oilfield waste facilities, into waters of the United States. If run-off from our owned or operated transfer stations or oilfield waste facilities or run-off or collected leachate from our owned or operated landfills is discharged into streams, rivers or other surface waters, the Clean Water Act would require us to apply for and obtain a discharge permit, conduct sampling and monitoring and, under certain circumstances, reduce the quantity of pollutants in such discharge. Also, virtually all landfills are required to comply with the EPA's storm water regulations issued in November 1990, which are designed to prevent contaminated landfill storm water run-off from flowing into surface waters. Spill prevention, control and countermeasure requirements of federal laws require appropriate containment berms and similar structures to help prevent the contamination of regulated waters in the event of a hydrocarbon storage tank spill, rupture or leak. We believe that our facilities comply in all material respects with the Clean Water Act requirements. Various states in which we operate or may operate in the future have been delegated authority to implement the Clean Water Act permitting requirements, and some of these states have adopted regulations that are more stringent than the federal Clean Water Act requirements. For example, states often require permits for discharges that may impact ground water as well as surface water. Federal and state regulatory agencies can impose administrative, civil and criminal penalties for non-compliance with discharge permits or other requirements of the Clean Water Act and analogous state laws and regulations. We believe that compliance with existing permits and regulatory requirements under the Clean Water Act and state counterparts will not have a material adverse effect on our business. Future changes to permits or regulatory requirements under the Clean Water Act, however, could adversely affect our business.

Safe Drinking Water Act, or SDWA

Our E&P underground injection operations are subject to the SDWA, as well as analogous state laws and regulations. Under the SDWA, the EPA established the underground injection control or UIC program, which includes requirements for permitting, testing, monitoring, record keeping, and reporting of injection well activities, as well as a prohibition against the migration of fluid containing any contaminant into underground sources of drinking water. State regulations require us to obtain a permit from the applicable regulatory agencies to operate our underground injection wells. We believe that we have obtained the necessary permits from these agencies for our underground injection wells and that we are in substantial compliance with permit conditions and state rules. Although we monitor the injection process of our wells, any leakage from the subsurface portions of the injection wells could cause degradation of fresh groundwater resources, potentially resulting in suspension of our UIC permit, issuance of fines and penalties from governmental agencies, incurrence of expenditures for remediation of the affected resource and imposition of liability by third parties for property damages and personal injuries. In addition, our sales of residual crude oil collected as part of the saltwater injection process could impose liability on us in the event that the entity to which the oil was transferred fails to manage and, as necessary, dispose of residual crude oil in accordance with applicable environmental and occupational health and safety laws.

Oil Pollution Act of 1990, or OPA

The OPA, as amended, establishes strict liability for owners and operators of facilities that are the site of a release of oil into the waters of the U.S. The OPA also imposes ongoing requirements on owners or operators of facilities that handle certain quantities of oil, including the preparation of oil spill response plans and proof of financial responsibility to cover environmental clean-up and restoration costs that could be incurred in conjunction with an oil spill. We handle oil at many of our facilities, and if a release of oil into the waters of the U.S. occurred at one of our facilities, we could be liable for cleanup costs and damages under the OPA.

The Comprehensive Environmental Response, Compensation, and Liability Act of 1980, or CERCLA

CERCLA established a regulatory and remedial program intended to provide for the investigation and cleanup of facilities where or from which a release of any hazardous substance into the environment has occurred or is threatened. CERCLA’s primary mechanism for remedying such problems is to impose strict joint and several liability for cleanup of facilities on current owners and operators of the site, former owners and operators of the site at the time of the disposal of the hazardous substances, any person who arranges for the transportation, disposal or treatment of the hazardous substances, and the transporters who select the disposal and treatment facilities, regardless of the care exercised by such persons. CERCLA also imposes liability for the cost of evaluating and remedying any damage to natural resources. The costs of CERCLA investigation and cleanup can be very substantial. Liability under CERCLA does not depend on the existence or disposal of “hazardous waste” as defined by RCRA; it can also be based on the release of even very small amounts of the more than 700 “hazardous substances” listed by the EPA, many of which can be found in household waste. In addition, the definition of “hazardous substances” in CERCLA incorporates substances designated as hazardous or toxic under the federal Clean Water Act, Clear Air Act and Toxic Substances Control Act.

We may handle hazardous substances within the meaning of CERCLA, or similar state statutes, in the course of our ordinary operations and, as a result, may be jointly and severally liable under CERCLA for all or part of the costs required to clean up sites at which these hazardous substances have been released into the environment. If we were found to be a responsible party for a CERCLA cleanup, the enforcing agency could hold us, or any other generator, transporter or the owner or operator of the contaminated facility, responsible for all investigative and remedial costs, even if others were also liable. Under such laws, we could be required to remove previously disposed substances and wastes (including substances disposed of or released by prior owners or operators) or remediate contaminated property (including groundwater contamination, whether from prior owners or operators or other historic activities or spills). These laws may also require us to conduct natural resource damage assessments and pay penalties for such damages. It is not uncommon for neighboring landowners and other third parties to file claims for personal injury and property damage allegedly caused by the release of hazardous substances or other pollutants into the environment. These laws and regulations may also expose us to liability for our acts that were in compliance with applicable laws at the time the acts were performed.

CERCLA also authorizes the imposition of a lien in favor of the United States on all real property subject to, or affected by, a remedial action for all costs for which a party is liable. Subject to certain procedural restrictions, CERCLA gives a responsible party the right to bring a contribution action against other responsible parties for their allocable shares of investigative and remedial costs. Our ability to obtain reimbursement from others for their allocable shares of such costs would be limited by our ability to find other responsible parties and prove the extent of their responsibility, their financial resources, and other procedural requirements. Various state laws also impose strict joint and several liability for investigation, cleanup and other damages associated with hazardous substance releases.

10

Petroleum hydrocarbons and other substances and wastes arising from E&P-related activities have been disposed of or released on or under many of our sites. At some of our facilities, we have conducted and continue to conduct monitoring or remediation of known soil and groundwater contamination, and we will continue to perform such monitoring and remediation of known contamination, including any post remediation groundwater monitoring that may be required, until the appropriate regulatory standards have been achieved. These monitoring and remediation efforts are usually overseen by state environmental regulatory agencies.

The Clean Air Act, or CAA

The CAA generally, through state implementation of federal requirements, regulates emissions of air pollutants from emissions sources, including certain landfills and oilfield waste facilities, based on factors such as the date of the construction and tons per year of emissions of regulated pollutants. The CAA and analogous state laws require permits for and impose other restrictions on facilities that have the potential to emit substances into the atmosphere above certain specified quantities or in a manner that could adversely affect environmental quality. Failure to obtain a permit or to comply with permit requirements could result in the imposition of substantial administrative, civil and even criminal penalties.

Larger landfills and landfills located in areas where the ambient air does not meet certain requirements of the CAA may be subject to even more extensive air pollution controls and emission limitations. In addition, the EPA has issued standards regulating the disposal of asbestos-containing materials. Air permits may be required to construct gas collection and flaring systems and composting operations, and operating permits may be required, depending on the potential air emissions. State air regulatory programs may implement the federal requirements but may impose additional restrictions. For example, some state air programs uniquely regulate odor and the emission of toxic air pollutants.

We do not believe that any of our oilfield waste operations are subject to CAA permitting or regulatory requirements for major sources of air emissions, but some of our facilities are subject to state “minor source” air permitting requirements and other state regulatory requirements for air emissions. In addition, our customers’ operations may be subject to existing and future CAA permitting and regulatory requirements that could have a material effect on their operations. For example, on April 17, 2012, the EPA approved new CAA rules requiring additional emissions controls and practices for oil and natural gas production wells, including wells that are the subject of hydraulic fracturing operations. These rules may increase the costs to our customers of developing and producing hydrocarbons, and as a result, may have an indirect and adverse effect on the amount of oilfield waste delivered to our facilities by our customers.

The EPA recently modified, or is in the process of modifying, standards promulgated under the CAA in a manner which could increase our compliance costs. For example, the EPA has recently modified or discussed modifying the municipal solid waste landfill new source performance standard, national ambient air quality standards applicable to particulate matter, carbon monoxide, and oxides of sulfur and nitrogen, and other standards to make them more stringent.

Climate Change Laws and Regulations

On September 27, 2006, California enacted AB 32, the Global Warming Solutions Act of 2006, which established the first statewide program in the United States to limit greenhouse gas, or GHG, emissions and impose penalties for non-compliance. Because landfill and collection operations emit GHGs, our operations in California are subject to regulations issued under AB 32. The California Air Resources Board, or CARB, has taken, and plans to take, various actions to implement AB 32. CARB approved a landfill methane control measure, which became effective in June 2010, and this measure requires that certain uncontrolled landfills install gas collection and control systems and also sets operating standards for gas collection and control systems. In addition, CARB implemented a GHG cap-and-trade program, which began imposing compliance obligations in January 2013.

State climate change laws could also affect our non-California operations. For example, the Western Climate Initiative, which once included seven states and four Canadian provinces, has developed GHG reduction strategies, among them a GHG cap-and-trade program.

The EPA’s regulation of GHG emissions under its CAA authority may also impact our operations. In 2009, the EPA made an endangerment finding allowing GHGs to be regulated under the CAA. The CAA requires stationary sources of air pollution to obtain New Source Review, or NSR, permits prior to construction and, in some cases, Title V operating permits. Pursuant to the EPA’s rulemakings and interpretations, certain Title V and NSR Prevention of Significant Deterioration, or PSD, permits issued on or after January 2, 2011, must address GHG emissions. As a result, new or modified emissions sources may be required to install Best Available Control Technology to limit GHG emissions. The EPA may in the future promulgate CAA New Source Performance Standards, or NSPS, applicable to landfills. The EPA’s Mandatory Greenhouse Gas Reporting Rule sets monitoring, recordkeeping, and reporting requirements applicable to certain landfills and other entities.

11

Regulation of GHG emissions from oil and gas E&P operations may also increase the costs to our customers of developing and producing hydrocarbons, and as a result, may have an indirect and adverse effect on the amount of oilfield waste delivered to our facilities by our customers. For example, a group of state attorneys general petitioned the EPA in December 2012 requesting that the EPA set methane emissions standards for the oil and gas sector pursuant to its CAA authority. The EPA has not yet acted on the petition, but the State of Colorado proposed rules in November 2013 that would directly regulate methane emissions from the oil and gas sector, and other states may follow.

These statutes and regulations increase the costs of our operations, and future climate change statutes and regulations may have an impact as well. If we are unable to pass such higher costs through to our customers, our business, financial condition and operating results could be adversely affected.

The Occupational Safety and Health Act of 1970, or the OSH Act

The OSH Act is administered by the Occupational Safety and Health Administration, or OSHA, and many state agencies whose programs have been approved by OSHA. The OSH Act establishes employer responsibilities for worker health and safety, including the obligation to maintain a workplace free of recognized hazards likely to cause death or serious injury, comply with adopted worker protection standards, maintain certain records, provide workers with required disclosures and implement certain health and safety training programs. Various OSHA standards may apply to our operations, including standards concerning notices of hazards, safety in excavation and demolition work, the handling of asbestos and asbestos-containing materials and worker training and emergency response programs.

Hydraulic Fracturing Regulation

We do not conduct hydraulic fracturing operations, but we do provide treatment, recovery and disposal services with respect to the fluids used and wastes generated by our customers in such operations, which are often necessary to drill and complete new wells and maintain existing wells. Recently, there has been increased public concern regarding the alleged potential for hydraulic fracturing to adversely affect drinking water supplies, and proposals have been made to enact separate federal legislation or legislation at the state and local government levels that would increase the regulatory burden imposed on hydraulic fracturing. Bills and regulations have been proposed and/or adopted at the federal, state and local levels that would regulate, restrict or prohibit hydraulic fracturing operations or require the reporting and public disclosure of chemicals used in the hydraulic fracturing process. Additionally, the EPA is currently studying the environmental impacts of hydraulic fracturing, including the impacts resulting from the treatment and disposal of E&P wastes associated with the hydraulic fracturing process. This study, expected to be completed in 2014, could result in increased regulation of hydraulic fracturing and new rules regarding the treatment and disposal of E&P wastes associated with fracturing.

Presently, hydraulic fracturing is regulated primarily at the state level, typically by state oil and natural gas commissions and similar agencies. Several states, including Louisiana, New Mexico, North Dakota, Oklahoma, Texas and Wyoming, where we conduct business, have adopted or proposed laws and/or regulations to require oil and natural gas operators to disclose information concerning their operations, which could result in increased public scrutiny.

If new federal, state or local laws or regulations that significantly restrict hydraulic fracturing are adopted, such legal requirements could result in delays, eliminate certain drilling and injection activities and make it more difficult or costly for our customers to perform hydraulic fracturing. Any such regulations limiting or prohibiting hydraulic fracturing could reduce oil and natural gas exploration and production activities by our customers and, therefore, adversely affect our business. Such laws or regulations could also materially increase our costs of compliance.

Flow Control/Interstate Waste Restrictions

Certain permits and approvals and state and local regulations may limit a landfill’s or transfer station’s ability to accept waste that originates from specified geographic areas, import out-of-state waste or wastes originating outside the local jurisdictions or otherwise discriminate against non-local waste. These restrictions, generally known as flow control restrictions, are controversial, and some courts have held that some state and local flow control schemes violate constitutional limits on state or local regulation of interstate commerce, while other state and local flow control schemes do not. Certain state and local jurisdictions may seek to enforce flow control restrictions through local legislation or contractually. These actions could limit or prohibit the importation of wastes originating outside of local jurisdictions or direct that wastes be handled at specified facilities. Such actions could adversely affect our transfer stations and landfills. These restrictions could also result in higher disposal costs for our collection operations. If we were unable to pass such higher costs through to our customers, our business, financial condition and operating results could be adversely affected.

12

State and Local Regulations

Each state in which we now operate or may operate in the future has laws and regulations governing the generation, storage, treatment, handling, transportation and disposal of solid waste, oilfield waste, occupational safety and health, water and air pollution and, in most cases, the siting, design, operation, maintenance, closure and post-closure maintenance of landfills and transfer stations. State and local permits and approval for these operations may be required and may be subject to periodic renewal, modification or revocation by the issuing agencies. In addition, many states have adopted statutes comparable to, and in some cases more stringent than, CERCLA. These statutes impose requirements for investigation and cleanup of contaminated sites and liability for costs and damages associated with such sites, and some provide for the imposition of liens on property owned by responsible parties.

Many municipalities also have enacted or could enact ordinances, local laws and regulations affecting our operations. These include zoning and health measures that limit solid waste management activities to specified sites or activities, flow control provisions that direct or restrict the delivery of solid wastes to specific facilities, laws that grant the right to establish franchises for collection services and bidding for such franchises, and bans or other restrictions on the movement of solid wastes into a municipality.

Various jurisdictions have enacted “fitness” regulations which allow agencies with authority over waste service contracts or permits to deny or revoke such contracts or permits based on the compliance history of the provider. Some jurisdictions also consider the compliance history of the parent, subsidiaries, or affiliated companies of the provider in making these decisions.

Permits or other land use approvals with respect to a landfill, as well as state or local laws and regulations, may specify the quantity of waste that may be accepted at the landfill during a given time period and/or the types of waste that may be accepted at the landfill. Once an operating permit for a landfill is obtained, it generally must be renewed periodically.

There has been an increasing trend at the state and local level to mandate and encourage waste reduction at the source and waste recycling, and to prohibit or restrict the disposal in landfills of certain types of solid wastes, such as food waste, yard waste, leaves, tires, computers and other electronic equipment waste, and painted wood and other construction and demolition debris. The enactment of regulations reducing the volume and types of wastes available for transport to and disposal in landfills could prevent us from operating our facilities at their full capacity.

Some state and local authorities enforce certain federal requirements in addition to state and local laws and regulations. For example, in some states, local or state authorities enforce requirements of RCRA, the OSH Act and parts of the CAA and the Clean Water Act instead of the EPA or OSHA, as applicable, and in some states such laws are enforced jointly by state or local and federal authorities.

E&P waste treatment, recovery and disposal operations are also regulated at the state level. For example, in Louisiana, the Louisiana Department of Natural Resources, or LDNR is responsible for regulating and permitting all oil and natural gas activities in the state, including E&P waste treatment and disposal operations, such as injection wells, land treatment and disposal facilities and transfer stations. As an example of the impact state regulations can have, in November 2009, the LDNR amended its regulations allowing operators to reuse certain E&P waste in hydraulic fracturing operations one time before the operators must dispose of the waste, and on June 20, 2010, the LDNR amended its regulations to allow operators to reuse E&P waste from hydraulic fracturing as many times as reasonably feasible. This regulatory action allows operators to, in some cases, forego sending their E&P waste to commercial disposal facilities such as ours, directly impacting our operations in Louisiana. State environmental laws and regulations require that we obtain permits and authorizations prior to the development and operation of E&P waste treatment and storage facilities and in connection with the disposal and transportation of certain types of waste. The applicable regulatory agencies strictly monitor production and disposal practices at all of our facilities. As part of our permitting process, we participate in annual monitoring, internal testing and third-party testing. A breach of such laws or regulations may result in suspension or revocation of necessary permits and authorizations, civil liability and imposition of fines and penalties. Moreover, if we experience a delay in obtaining, are unable to obtain, or suffer the revocation of required permits, we may be unable to serve our customers, our operations may be interrupted, and our growth and revenue may be limited.

Public Utility Regulation

In some states, public authorities regulate the rates that landfill operators may charge. The adoption of rate regulation or the reduction of current rates in states in which we own or operate landfills could adversely affect our business, financial condition and operating results.

13

Solid waste collection services in all unincorporated areas of Washington and in electing municipalities in Washington are provided under G Certificates awarded by the WUTC. In association with the regulation of solid waste collection service levels in these areas, the WUTC also reviews and approves rates for regulated solid waste collection and transportation service. 

RISK MANAGEMENT, INSURANCE AND FINANCIAL SURETY BONDS

Risk Management

We maintain environmental and other risk management programs that we believe are appropriate for our business.  Our environmental risk management program includes evaluating existing facilities and potential acquisitions for environmental law compliance.  We do not presently expect environmental compliance costs to increase materially above current levels, but we cannot predict whether future acquisitions will cause such costs to increase.  We also maintain a worker safety program that encourages safe practices in the workplace.  Operating practices at our operations emphasize minimizing the possibility of environmental contamination and litigation.  Our facilities comply in all material respects with applicable federal and state regulations. 

Insurance 

We have a high deductible or self-insured retention insurance program for automobile liability, general liability, employer’s liability claims, environmental liability, cyber liability, employment practices liability and directors’ and officers’ liability as well as for employee group health insurance, property and workers’ compensation.  Our loss exposure for insurance claims is generally limited to per incident deductibles or self-insured retentions.  Losses in excess of deductible or self-insured retention levels are insured subject to policy limits.  Under our current insurance program, we carry per incident deductibles or self-insured retentions of $2 million for automobile liability claims, $1.5 million for workers’ compensation and employer’s liability claims, $1 million for general liability claims, $500,000 for directors’ and officers’ liability claims, $250,000 for employee group health insurance and employment practices liability, and primarily $100,000 for property claims.  We also have a policy covering risks associated with cyber liability that has a $50,000 self-insured retention. Additionally, we have umbrella policies with insurance companies for automobile liability, general liability and employer’s liability. Since workers’ compensation is a statutory coverage limited by the various state jurisdictions, the umbrella coverage is not applicable.  Also, our umbrella policy does not cover property claims, as the insurance limits for these claims are in accordance with the replacement values of the insured property.  From time to time, actions filed against us include claims for punitive damages, which are generally excluded from coverage under our liability insurance policies.  

We carry environmental protection insurance which has a $250,000 per incident deductible.  This insurance policy covers all owned or operated landfills, certain transfer stations and other facilities, subject to the policy terms and conditions.  Our policy provides insurance for new pollution conditions that originate after the commencement of our coverage.  Pollution conditions existing prior to the commencement of our coverage, if found, could be excluded from coverage. 

Financial Surety Bonds

We use financial surety bonds for a variety of corporate guarantees.  The financial surety bonds are primarily used for guaranteeing municipal contract performance and providing financial assurances to meet asset closure and retirement requirements under certain environmental regulations.  In addition to surety bonds, such guarantees and obligations may also be met through alternative financial assurance instruments, including insurance, letters of credit and restricted asset deposits. At December 31, 2013 and 2012, we had provided customers and various regulatory authorities with surety bonds in the aggregate amount of approximately $304.4 million and $277.8 million, respectively, to secure our asset closure and retirement requirements and $89.2 million and $83.7 million, respectively, to secure performance under collection contracts and landfill operating agreements. 

We own a 9.9% interest in a company that, among other activities, issues financial surety bonds to secure landfill final capping, closure and post-closure obligations for companies operating in the solid waste sector, including a portion of our own. 

EMPLOYEES

At December 31, 2013, we employed 6,633 employees, of which 823, or approximately 12.4% of our workforce, were employed under collective bargaining agreements, primarily with the Teamsters Union.  These collective bargaining agreements are renegotiated periodically.  We have seven collective bargaining agreements covering 319 employees that have expired or are set to expire during 2014.  We do not expect any significant disruption in our overall business in 2014 as a result of labor negotiations, employee strikes or organizational efforts. 

14

SEASONALITY 

We expect our operating results to vary seasonally, with revenues typically lowest in the first quarter, higher in the second and third quarters and lower in the fourth quarter than in the second and third quarters.  This seasonality reflects (a) the lower volume of solid waste generated during the late fall, winter and early spring because of decreased construction and demolition activities during winter months in the U.S., and (b) reduced E&P activity during harsh weather conditions, with expected fluctuation between our highest and lowest quarters of approximately 10% to 13%.  In addition, some of our operating costs may be higher in the winter months.  Adverse winter weather conditions slow waste collection activities, resulting in higher labor and operational costs.  Greater precipitation in the winter increases the weight of collected municipal solid waste, resulting in higher disposal costs, which are calculated on a per ton basis.

ITEM 1A. RISK FACTORS

Certain statements contained in this Annual Report on Form 10-K are forward-looking in nature, including statements related to our ability to obtain additional exclusive arrangements, our ability to generate internal growth, our ability to generate free cash flow and reduce our leverage, our ability to provide adequate cash to fund our operating activities, our ability to draw on our credit facility or raise additional capital, the impact of global economic conditions on our volume, business and results of operations, the effects of landfill special waste projects on volume results, the effects of seasonality on our business and results of operations, demand for recyclable commodities and recyclable commodity pricing, our ability to grow through acquisitions and our expectations with respect to the impact of acquisitions on our expected revenues and expenses, our ability to expand permitted capacity at landfills we own or operate, our expectations with respect to capital expenditures, and our expectations with respect to the purchase of fuel and fuel prices.  These statements can be identified by the use of forward-looking terminology such as “believes,” “expects,” “may,” “will,” “should,” or “anticipates,” or the negative thereof or comparable terminology, or by discussions of strategy. 

Our business and operations are subject to a variety of risks and uncertainties and, consequently, actual results may differ materially from those projected by any forward-looking statements.  Factors that could cause actual results to differ from those projected include, but are not limited to, those listed below and elsewhere in this report.  There may be additional risks of which we are not presently aware or that we currently believe are immaterial which could have an adverse impact on our business.  We make no commitment to revise or update any forward-looking statements in order to reflect events or circumstances that may change. 

Risks Related to Our Business 

Our results are vulnerable to economic conditions. 

Our business and financial results would be harmed by downturns in the general economy of the regions in which we operate and other factors affecting those regions. Negative effects of a weak economy include decreases in volume generally associated with the drilling and construction industries, reduced personal consumption and declines in recycled commodity prices.  In an economic slowdown, we also experience the negative effects of increased competitive pricing pressure, customer turnover, and reductions in customer service requirements.  Worsening economic conditions or a prolonged or recurring economic recession could adversely affect our operating results and expected seasonal fluctuations.  Further, we cannot assure you that any improvement in economic conditions after such a downturn will result in an immediate, if at all positive, improvement in our operating results or cash flows.

Our industry is highly competitive and includes larger and better capitalized companies, companies with lower prices, return expectations or other advantages, and governmental service providers, which could adversely affect our ability to compete and our operating results. 

Our industry is highly competitive and requires substantial labor and capital resources.  Some of the markets in which we compete or will seek to compete are served by one or more large, national companies, as well as by regional and local companies of varying sizes and resources, some of which we believe have accumulated substantial goodwill in their markets.  Some of our competitors may also be better capitalized than we are, have greater name recognition than we do, or be able to provide or be willing to bid their services at a lower price than we may be willing to offer.  In addition, existing and future competitors may develop or offer services or new technologies, new facilities or other advantages. Our inability to compete effectively could hinder our growth or negatively impact our operating results. 

In our solid waste business, we also compete with counties, municipalities and solid waste districts that maintain or could in the future choose to maintain their own waste collection and disposal operations, including through the implementation of flow control ordinances or similar legislation.  These operators may have financial advantages over us because of their access to user fees and similar charges, tax revenues and tax-exempt financing. 

In our E&P waste business, we compete for disposal volumes with existing facilities owned by third parties, and we face potential competition from new facilities that are currently under development. Increased competition in certain markets may result in lower pricing and decreased volumes at our facilities. In addition, customers in certain markets may decide to use internal disposal methods for the treatment and disposal of their waste.

19

Our E&P waste business depends on the level of drilling and production activity in the basins in which we operate and the willingness of E&P companies to outsource their waste services activities.

The demand for E&P waste services in the basins in which we operate may be adversely affected by the level of drilling activity and the willingness of E&P companies to outsource their waste services activities. The amount of drilling and production activity can be affected by a variety of external factors, including: the supply of and demand for oil and natural gas, oil and natural gas prices, expectations for oil and natural gas prices, production rates, development, production and transportation costs, discovery rates, regulations, domestic and worldwide economic conditions, credit markets, and political stability. We also are largely dependent on the willingness of E&P companies to outsource their waste services activities generally, and to us specifically rather than to our competitors. To the extent that E&P companies, including our current customers, elect not to outsource their E&P waste services activities or market prices decline, our results may be affected. E&P companies have varying market shares within basins, and, depending on that share, the loss of any customer in a given basin could have an adverse effect on results of operations and cash flows in that market. Furthermore, while our E&P customers frequently require us to enter into master service agreements, such agreements typically do not include volume commitments from the customers and typically are terminable at the discretion of either party. These factors introduce greater volatility to our revenues and operating margins for this business, which could have a material adverse effect on our financial position, results of operations and cash flows.

We have limited experience in running an E&P waste treatment, recovery and disposal business.

In 2012, we acquired the non-hazardous E&P waste treatment, recovery and disposal businesses of R360, which are included in what we refer to as our E&P waste business. Our E&P waste business is expected to account for approximately 15% of our revenues. While we have conducted limited E&P waste treatment and disposal prior to the R360 acquisition, the E&P waste business is outside of our historical core business of municipal solid waste. We expect revenues and operating margins, as well as customer demand, for our E&P waste business to be more volatile than our historical MSW business. If we are unable to effectively manage this business, or if we do not adequately anticipate the volatility of this business, our financial condition and results of operations may suffer.

Competition for acquisition candidates, consolidation within the waste industry and economic and market conditions may limit our ability to grow through acquisitions. 

We seek to grow through strategic acquisitions in addition to internal growth. Although we have and expect to continue to identify numerous acquisition candidates that we believe may be suitable, we may not be able to acquire them at prices or on terms and conditions favorable to us. 

Other companies have adopted or may in the future adopt our strategy of acquiring and consolidating regional and local businesses.  We expect that increased consolidation in the solid waste services industry will continue to reduce the number of attractive acquisition candidates.  Moreover, general economic conditions and the environment for attractive investments may affect the desire of the owners of acquisition candidates to sell their companies.  As a result, we may have fewer acquisition opportunities, and those opportunities may be on less attractive terms than in the past, which could cause a reduction in our rate of growth from acquisitions. 

Our ability to access the capital markets may be severely restricted at a time when we would like, or need, to do so. While we expect we will be able to fund some of our acquisitions with our existing resources, additional financing to pursue additional acquisitions may be required.  However, particularly if market conditions deteriorate, we may be unable to secure additional financing or any such additional financing may be available to us on unfavorable terms, which could have an impact on our flexibility to pursue additional acquisition opportunities.  In addition, disruptions in the capital and credit markets could adversely affect our ability to draw on our credit facility or raise other capital.  Our access to funds under the credit facility is dependent on the ability of the banks that are parties to the facility to meet their funding commitments.  Those banks may not be able to meet their funding commitments if they experience shortages of capital and liquidity or if they experience excessive volumes of borrowing requests within a short period of time.

Our indebtedness could adversely affect our financial condition and limit our financial flexibility. 

As of December 31, 2013, we had approximately $2.1 billion of total indebtedness outstanding, and we may incur additional debt in the future.  This amount of indebtedness could:

· increase our vulnerability to general adverse economic and industry conditions;

· expose us to interest rate risk since a majority of our indebtedness is at variable rates; 

· limit our ability to obtain additional financing or refinancings at attractive rates; 

· require the dedication of a substantial portion of our cash flow from operations to the payment of principal of, and interest on, our indebtedness, thereby reducing the availability of such cash flow to fund our growth strategy, working capital, capital expenditures, dividends, share repurchases and other general corporate purposes; 

· limit our flexibility in planning for, or reacting to, changes in our business and the industry; and 

· place us at a competitive disadvantage relative to our competitors with less debt. 

20

Further, our outstanding indebtedness is subject to financial and other covenants, which may be affected by changes in economic or business conditions or other events that are beyond our control. If we fail to comply with the covenants under any of our indebtedness, we may be in default under the loan, which may entitle the lenders to accelerate the debt obligations. A default under one of our loans could result in cross-defaults under our other indebtedness. In order to avoid defaulting on our indebtedness, we may be required to take actions such as reducing or delaying capital expenditures, reducing or eliminating dividends or stock repurchases, selling assets, restructuring or refinancing all or part of our existing debt, or seeking additional equity capital, any of which may not be available on terms that are favorable to us, if at all.

Price increases may not be adequate to offset the impact of increased costs, or may cause us to lose volume.

We seek price increases necessary to offset increased costs, to improve operating margins and to obtain adequate returns on our deployed capital.  Contractual, general economic, competitive or market-specific conditions may limit our ability to raise prices.  As a result of these factors, we may be unable to offset increases in costs, improve operating margins and obtain adequate investment returns through price increases.  We may also lose volume to lower-price competitors.

Fluctuations in prices for recycled commodities that we sell and rebates we offer to customers may cause our revenues and operating results to decline.

We provide recycling services to some of our customers.  The majority of the recyclables we process for sale are paper products that are shipped to customers in Asia.  The sale prices of and demands for recyclable commodities, particularly paper products, are frequently volatile and when they decline, our revenues, operating results and cash flows will be affected.  Our recycling operations offer rebates to customers based on the market prices of commodities we buy to process for resale.  Therefore, if we recognize increased revenues resulting from higher prices for recyclable commodities, the rebates we pay to suppliers will also increase, which also may impact our operating results. 

The seasonal nature of our business and “event-driven” waste projects cause our results to fluctuate. 

Based on historic trends, we expect our operating results to vary seasonally, with revenues typically lowest in the first quarter, higher in the second and third quarters, and lower in the fourth quarter than in the second and third quarters.  We expect the fluctuation in our revenues between our highest and lowest quarters to be approximately 10% to 13%.  This seasonality reflects the lower volume of solid waste generated during the late fall, winter and early spring because of decreased construction and demolition activities during the winter months in the U.S., and reduced E&P activity during harsh weather conditions.  Conversely, mild winter weather conditions may reduce demand for oil and natural gas, which may cause our customers to curtail their drilling programs, which could result in production of lower volumes of E&P waste.

Adverse winter weather conditions slow waste collection activities, resulting in higher labor and operational costs.  Greater precipitation in the winter increases the weight of collected waste, resulting in higher disposal costs, which are calculated on a per ton basis.  Certain weather conditions, including severe storms, may result in temporary suspension of our operations, which can significantly impact the operating results of the affected areas. Conversely, weather-related occurrences and other “event-driven” waste projects can boost revenues through heavier weight loads or additional work for a limited time period. These factors impact period-to-period comparisons of financial results, and our stock price may be negatively affected by these variations.

We may lose contracts through competitive bidding, early termination or governmental action. 

We derive a significant portion of our revenues from market areas where we have exclusive arrangements, including franchise agreements, municipal contracts and G Certificates.  Many franchise agreements and municipal contracts are for a specified term and are, or will be, subject to competitive bidding in the future.  For example, we have approximately 301 contracts, representing approximately 3.5% of our annual revenues, which are set for expiration or automatic renewal on or before December 31, 2014.  Although we intend to bid on additional municipal contracts and franchise agreements, we may not be the successful bidder.  In addition, some of our customers, including municipalities, may terminate their contracts with us before the end of the terms of those contracts.  Similar risks may affect contracts that we are awarded to operate municipally-owned assets, such as landfills. For example, see the discussion regarding the Madera County, California Materials Recovery Facility Contract Litigation under the “Legal Proceedings” section of Note 11 of our consolidated financial statements included in Item 8 of this report. 

21

Governmental action may also affect our exclusive arrangements.  Municipalities may annex unincorporated areas within counties where we provide collection services.  As a result, our customers in annexed areas may be required to obtain services from competitors that have been franchised by the annexing municipalities to provide those services.  In addition, municipalities in which we provide services on a competitive basis may elect to franchise those services.  Unless we are awarded franchises by these municipalities, we will lose customers.  Municipalities may also decide to provide services to their residents themselves, on an optional or mandatory basis, causing us to lose customers.  Municipalities in Washington may, by law, annex any unincorporated territory, which could remove such territory from an area covered by a G Certificate issued to us by the WUTC.  Such occurrences could subject more of our Washington operations to competitive bidding.  Moreover, legislative action could amend or repeal the laws governing WUTC regulation, which could harm our competitive position by subjecting more areas to competitive bidding and/or overlapping service.  If we are not able to replace revenues from contracts lost through competitive bidding or early termination or from the renegotiation of existing contracts with other revenues within a reasonable time period, our revenues could decline.

Increases in labor costs could impact our financial results. 

Labor is one of our highest costs and relatively small increases in labor costs per employee could materially affect our cost structure.  We compete with other businesses in our markets for qualified employees and the labor supply is sometimes tight in our markets.  In our E&P waste business, for example, we are exposed to the cyclical variations in demand that are particular to the development and production of oil and natural gas in the U.S. A shortage of qualified employees would require us to incur additional costs related to wages and benefits, to hire more expensive temporary employees or to contract for services with more expensive third-party vendors.

Increases in the price of diesel or compressed natural gas fuel may adversely affect our collection business and reduce our operating margins. 

The market price of diesel fuel is volatile.  We generally purchase diesel fuel at market prices, and such prices have fluctuated significantly in recent years.  A significant increase in market prices for fuel could adversely affect our waste collection business through a combination of higher fuel and disposal-related transportation costs and reduce our operating margins and reported earnings.  To manage a portion of this risk, we have entered into fuel hedge agreements related to forecasted diesel fuel purchases and fixed-price fuel purchase contracts.  During periods of falling diesel fuel prices, our hedge payable positions may increase and it may become more expensive to purchase fuel under fixed-price fuel purchase contracts than at market prices. 

We utilize compressed natural gas, or CNG, in a small percentage of our fleet and may convert more of our fleet from diesel fuel to CNG over time. The market price of CNG is also volatile; a significant increase in such cost could adversely affect our operating margins and reported earnings.

Labor union activity could divert management attention and adversely affect our operating results. 

From time to time, labor unions attempt to organize our employees.  Some groups of our employees are represented by unions, and we have negotiated collective bargaining agreements with most of these unions.  We are currently engaged in negotiations with other labor unions attempting to organize groups of our employees.  Additional groups of employees may seek union representation in the future.  As a result of these activities, we may be subjected to unfair labor practice charges, complaints and other legal and administrative proceedings initiated against us by unions or the National Labor Relations Board, which could negatively impact our operating results. Negotiating collective bargaining agreements with these unions could divert management attention, which could also adversely affect operating results.  If we are unable to negotiate acceptable collective bargaining agreements, we might have to wait through “cooling off” periods, which are often followed by union-initiated work stoppages, including strikes.  Depending on the type and duration of any labor disruptions, our operating expenses could increase significantly, which could adversely affect our financial condition, results of operations and cash flows.

We could face significant withdrawal liability if we withdraw from participation in one or more multiemployer pension plans in which we participate and the accrued pension benefits are not fully funded.

We participate in two “multiemployer” pension plans administered by employee and union trustees. We make periodic contributions to these plans to fund pension benefits for our union employees pursuant to our various contractual obligations to do so. In the event that we withdraw from participation in or otherwise cease our contributions to one of these plans, then applicable law regarding withdrawal liability could require us to make additional contributions to the plan if the accrued benefits are not fully funded, and we would have to reflect that “withdrawal liability” as an expense in our consolidated statement of operations and as a liability on our consolidated balance sheet. Our withdrawal liability for any multiemployer plan would depend on the extent to which accrued benefits are funded. In the ordinary course of our renegotiation of collective bargaining agreements with labor unions that participate in these plans, we may decide to discontinue participation in a multiemployer plan, and in that event, we could face withdrawal liability. Some multiemployer plans in which we participate may from time to time have significant accrued benefits that are not funded. The size of our potential withdrawal liability may be affected by the level of unfunded accrued benefits, the actuarial assumptions used by the plan and the investment gains and losses experienced by the plan.

22

Our financial results could be adversely affected by impairments of goodwill or indefinite-lived intangibles.

As a result of our acquisition strategy, we have a material amount of goodwill and indefinite-lived intangibles recorded in our financial statements. We do not amortize our existing goodwill or indefinite-lived intangibles and are required to test goodwill and indefinite-lived intangibles for impairment annually using the two-step process prescribed in the accounting guidance. The first step is a screen for potential impairment, using either a qualitative or quantitative assessment, while the second step measures the amount of the impairment, if any. We perform the first step of the required impairment tests of goodwill and indefinite-lived intangible assets annually using a quantitative assessment.

We have an indefinite-lived intangible asset related to an operating permit at our recycling facility in the Albany, NY market (“Sierra Processing”) with a carrying value of $42.3 million at December 31, 2012 and 2013, that experienced a temporary decline in its estimated fair value in 2012 due to a decline in profitability resulting from decreases in revenue from reductions in market prices for recyclable commodities, increases in logistics and processing expenses and purchasing recyclable commodities for processing and resale at prices that resulted in Sierra Processing recognizing losses on the final sale. In 2013, we implemented cost controls, recognized operating efficiencies that improved per ton processing costs and ceased the purchase of recyclable commodities at prices that did not provide an appropriate profit margin upon final sale. As a result of these changes, profitability at Sierra Processing improved and our 2013 indefinite-lived impairment testing determined that the fair value of the operating permit exceeded its carrying value; therefore, no impairment charge has been recorded as of December 31, 2013. If we are unable to maintain the cost controls and operating efficiencies we have implemented, or if future market prices and processing volumes at Sierra Processing are significantly less than our expectations, we may be required to recognize an impairment charge on this indefinite-lived intangible asset in the future.

We may incur charges related to capitalized expenditures of landfill development projects, which would decrease our earnings. 

In accordance with U.S. generally accepted accounting principles, we capitalize some expenditures and advances relating to landfill development projects.  We expense indirect costs such as executive salaries, general corporate overhead and other corporate services as we incur those costs.  We charge against earnings any unamortized capitalized expenditures and advances (net of any amount that we estimate we will recover, through sale or otherwise) that relate to any operation that is permanently shut down or determined to be impaired and any landfill development project that we do not expect to complete.  For example, if we are unsuccessful in our attempts to obtain or defend permits that we are seeking or have been awarded to operate or expand a landfill, we will no longer generate anticipated income from the landfill and we will be required to expense in a future period the amount of capitalized expenditures related to the landfill or expansion project, less the recoverable value of the property and other amounts recovered. Additionally, we may incur increased operating expenses to dispose of the previously internalized waste that would need to be transported to another disposal location. Any such charges could have a material adverse effect on our results of operations for that period and could decrease our stock price. For example, see the discussion regarding the Chaparral, New Mexico Landfill Permit Litigation, the Harper County, Kansas Permit Litigation and the Solano County, California Measure E/Landfill Expansion Litigation under the “Legal Proceedings” section of Note 11 of our consolidated financial statements included in Item 8 of this report.

Pending or future litigation or governmental proceedings could result in material adverse consequences, including judgments or settlements.

We are, and from time to time become, involved in lawsuits, regulatory inquiries, and governmental and other legal proceedings arising out of the ordinary course of our business. Many of these matters raise complicated factual and legal issues and are subject to uncertainties and complexities, all of which makes the matters costly to address. For example, in recent years, wage and hour and employment laws have changed regularly and become increasingly complex, which has fostered litigation, including purported class actions. Similarly, citizen suits brought pursuant to environmental laws, such as those regulating the treatment of storm water runoff, have proliferated. The timing of the final resolutions to lawsuits, regulatory inquiries, and governmental and other legal proceedings is uncertain. Additionally, the possible outcomes or resolutions to these matters could include adverse judgments or settlements, either of which could require substantial payments, adversely affecting our consolidated financial condition, results of operations and cash flows. See discussion under the “Legal Proceedings” section of Note 11 of our consolidated financial statements included in Item 8 of this report.

23

We may be subject in the normal course of business to judicial, administrative or other third-party proceedings that could interrupt or limit our operations, require expensive remediation, result in adverse judgments, settlements or fines and create negative publicity. 

Governmental agencies may, among other things, impose fines or penalties on us relating to the conduct of our business, attempt to revoke or deny renewal of our operating permits, franchises or licenses for violations or alleged violations of environmental laws or regulations or as a result of third-party challenges, require us to install additional pollution control equipment or require us to remediate potential environmental problems relating to any real property that we or our predecessors ever owned, leased or operated or any waste that we or our predecessors ever collected, transported, disposed of or stored.  Individuals, citizens groups, trade associations or environmental activists may also bring actions against us in connection with our operations that could interrupt or limit the scope of our business.  Any adverse outcome in such proceedings could harm our operations and financial results and create negative publicity, which could damage our reputation, competitive position and stock price. 

Increases in insurance costs and the amount that we self-insure for various risks could reduce our operating margins and reported earnings. 

We maintain high deductible insurance policies for automobile, general, employer’s, environmental and directors’ and officers’ liability as well as for employee group health insurance, property insurance and workers’ compensation.  We carry umbrella policies for certain types of claims to provide excess coverage over the underlying policies and per incident deductibles.  The amounts that we effectively self-insure could cause significant volatility in our operating margins and reported earnings based on the event and claim costs of incidents, accidents, injuries and adverse judgments.  Our insurance accruals are based on claims filed and estimates of claims incurred but not reported and are developed by our management with assistance from our third-party actuary and our third-party claims administrator.  To the extent these estimates are inaccurate, we may recognize substantial additional expenses in future periods that would reduce operating margins and reported earnings.  Furthermore, while we maintain liability insurance, our insurance is subject to coverage limitations. If we were to incur substantial liability, our insurance coverage may be inadequate to cover the entirety of such liability. This could have a material adverse effect on our financial position, results of operations and cash flows. One form of coverage limitation concerns claims for punitive damages, which are generally excluded from coverage under all of our liability insurance policies.  A punitive damage award could have an adverse effect on our reported earnings in the period in which it occurs.  Significant increases in premiums on insurance that we retain also could reduce our margins. 

A portion of our growth and future financial performance depends on our ability to integrate acquired businesses, and the success of our acquisitions. 

A component of our growth strategy involves achieving economies of scale and operating efficiencies by growing through acquisitions.  We may not achieve these goals unless we effectively combine the operations of acquired businesses with our existing operations.  Similar risks may affect contracts that we are awarded to operate municipally-owned assets, such as landfills. In addition, we are not always able to control the timing of our acquisitions.  Our inability to complete acquisitions within the time frames that we expect may cause our operating results to be less favorable than expected, which could cause our stock price to decline.

Even if we are able to make acquisitions on advantageous terms and are able to integrate them successfully into our operations and organization, some acquisitions may not fulfill our anticipated financial or strategic objectives in a given market due to factors that we cannot control, such as market position, competition, customer base, loss of key employees, third-party legal challenges or governmental actions.  For example, see the discussion regarding the Solano County, California Measure E/Landfill Expansion Litigation under the “Legal Proceedings” section of Note 11 of our consolidated financial statements included in Item 8 of this report. In addition, we may change our strategy with respect to a market or acquired businesses and decide to sell such operations at a loss, or keep those operations and recognize an impairment of goodwill and/or intangible assets.  Similar risks may affect contracts that we are awarded to operate municipally-owned assets, such as landfills. 

Each business that we acquire or have acquired may have liabilities or risks that we fail or are unable to discover, or that become more adverse to our business than we anticipated at the time of acquisition. 

It is possible that the corporate entities or sites we have acquired, or which we may acquire in the future, have liabilities or risks in respect of former or existing operations or properties, or otherwise, which we have not been able to identify and assess through our due diligence investigations.  As a successor owner, we may be legally responsible for those liabilities that arise from businesses that we acquire.  Even if we obtain legally enforceable representations, warranties and indemnities from the sellers of such businesses, they may not cover the liabilities fully or the sellers may not have sufficient funds to perform their obligations.  Some environmental liabilities, even if we do not expressly assume them, may be imposed on us under various regulatory schemes and other applicable laws.  In addition, our insurance program may not cover such sites and will not cover liabilities associated with some environmental issues that may have existed prior to attachment of coverage.  A successful uninsured claim against us could harm our financial condition or operating results. Additionally, there may be other risks of which we are unaware that could have an adverse effect on businesses that we acquire or have acquired.  For example, interested parties may bring actions against us in connection with operations that we acquire or have acquired.  Furthermore, risks or liabilities we judge to be not material or remote at the time of acquisition may develop into more serious risks to our business. Any adverse outcome resulting from such risks or liabilities could harm our operations and financial results and create negative publicity, which could damage our reputation, competitive position and stock price. 

24

Our financial results are based upon estimates and assumptions that may differ from actual results. 

In preparing our consolidated financial statements in accordance with U.S. generally accepted accounting principles, estimates and assumptions are made that affect the accounting for and recognition of assets, liabilities, revenues and expenses.  These estimates and assumptions must be made because certain information that is used in the preparation of our financial statements is dependent on future events, cannot be calculated with a high degree of precision from data available or is not capable of being readily calculated based on generally accepted methodologies.  In some cases, these estimates are particularly difficult to determine and we must exercise significant judgment.  The most difficult, subjective and complex estimates and the assumptions that deal with the greatest amount of uncertainty are related to our accounting for landfills, self-insurance accruals, income taxes, allocation of acquisition purchase price, asset impairments and litigation, claims and assessments.  Actual results for all estimates could differ materially from the estimates and assumptions that we use, which could have an adverse effect on our financial condition and results of operations. 

Our accruals for our landfill site closure and post-closure costs may be inadequate. 

We are required to pay capping, closure and post-closure maintenance costs for landfill sites that we own and operate.  We are also required to pay capping, closure and post-closure maintenance costs for five of our six operated landfills for which we have life-of-site agreements.  Our obligations to pay closure or post-closure costs may exceed the amount we have accrued and reserved and other amounts available from funds or reserves established to pay such costs.  In addition, the completion or closure of a landfill site does not end our environmental obligations.  After completion or closure of a landfill site, there exists the potential for unforeseen environmental problems to occur that could result in substantial remediation costs.  Paying additional amounts for closure or post-closure costs and/or for environmental remediation could harm our financial condition or operating results.

We depend significantly on the services of the members of our senior and regional management team, and the departure of any of those persons could cause our operating results to suffer. 

Our success depends significantly on the continued individual and collective contributions of our senior and regional management team.  Of particular importance to our success are the services of our founder, Chief Executive Officer and Chairman, Ronald J. Mittelstaedt.  Key members of our management, including Mr. Mittelstaedt, have entered into employment agreements, but we may not be able to enforce these agreements.  The loss of the services of any member of our senior and regional management or the inability to hire and retain experienced management personnel could harm our operating results. 

Our decentralized decision-making structure could allow local managers to make decisions that adversely affect our operating results. 

We manage our operations on a decentralized basis.  Local managers have the authority to make many decisions concerning their operations without obtaining prior approval from executive officers, subject to compliance with general company-wide policies.  Poor decisions by local managers could result in the loss of customers or increases in costs, in either case adversely affecting operating results. 

Liabilities for environmental damage may adversely affect our financial condition, business and earnings. 

We may be liable for any environmental damage that our current or former operations cause, including damage to neighboring landowners or residents, particularly as a result of the contamination of soil, groundwater or surface water, and especially drinking water, or to natural resources.  We may be liable for damage resulting from conditions existing before we acquired these operations. Even if we obtain legally enforceable representations, warranties and indemnities from the sellers of these operations, they may not cover the liabilities fully or the sellers may not have sufficient funds to perform their obligations.

We may also be liable for any on-site environmental contamination caused by pollutants or hazardous substances whose transportation, treatment or disposal we or our predecessors arranged or conducted.  Some environmental laws and regulations may impose strict, joint and several liability in connection with releases of regulated substances into the environment. Therefore, in some situations we could be exposed to liability as a result of our conduct that was lawful at the time it occurred or the conduct of, or conditions caused by, third parties. If we were to incur liability for environmental damage, environmental cleanups, corrective action or damage not covered by insurance or in excess of the amount of our coverage, our financial condition or operating results could be materially adversely affected. 

25

We rely on computer systems to run our business and disruptions or privacy breaches in these systems could impact our ability to service our customers and adversely affect our financial results, damage our reputation, and expose us to litigation risk.

Our businesses rely on computer systems to provide customer information, process customer transactions and provide other general information necessary to manage our businesses. We have an active disaster recovery plan in place that we review and test. However, our computer systems are subject to damage or interruption due to system conversions, power outages, computer or telecommunication failures, catastrophic events such as fires, tornadoes and hurricanes and usage errors by our employees. Given the unpredictability of the timing, nature and scope of such disruptions, we could potentially be subject to operational delays and interruptions in our ability to provide services to our customers. Any disruption caused by the unavailability of our computer systems could adversely affect our revenues or could require significant investment to fix or replace them, and, therefore, could affect our operating results.

In addition, cyber-security attacks are evolving and include, but are not limited to, malicious software, attempts to gain unauthorized access to data and other electronic security breaches that could lead to disruptions in systems, unauthorized release of confidential or otherwise protected information and corruption of data. If the network of security controls, policy enforcement mechanisms or monitoring systems we use to address these threats to technology fail, the compromising of confidential or otherwise protected company, customer or employee information, destruction or corruption of data, security breaches or other manipulation or improper use of our systems and networks could result in financial losses from remedial actions, loss of business or potential liability and damage to our reputation.

If we are not able to develop and protect intellectual property, or if a competitor develops or obtains exclusive rights to a breakthrough technology, our financial results may suffer.

Our existing and proposed service offerings to customers may require that we develop or license, and protect, new technologies. We may experience difficulties or delays in the research, development, production and/or marketing of new products and services which may negatively impact our operating results and prevent us from recouping or realizing a return on the investments required to bring new products and services to market. Further, protecting our intellectual property rights and combating unlicensed copying and use of intellectual property is difficult, and any inability to obtain or protect new technologies could impact our services to customers and development of new revenue sources. Additionally, a competitor may develop or obtain exclusive rights to a “breakthrough technology” that provides a revolutionary change in traditional waste management. If we have inferior intellectual property to our competitors, our financial results may suffer. 

Risks Related to Our Industry

Our financial and operating performance may be affected by the inability to renew landfill operating permits, obtain new landfills and expand existing ones. 

We currently own and/or operate 55 landfills.  Our ability to meet our financial and operating objectives may depend in part on our ability to acquire, lease, or renew landfill operating permits, expand existing landfills and develop new landfill sites, especially in our E&P waste business.  It has become increasingly difficult and expensive to obtain required permits and approvals to build, operate and expand solid waste management facilities, including landfills and transfer stations.  Although the process generally takes less time, the process of obtaining permits and approvals for E&P landfills has similar uncertainties. Operating permits for landfills in states where we operate must generally be renewed every five to ten years, although some permits are required to be renewed more frequently.  These operating permits often must be renewed several times during the permitted life of a landfill.  The permit and approval process is often time consuming, requires numerous hearings and compliance with zoning, environmental and other requirements, is frequently challenged by special interest and other groups, and may result in the denial of a permit or renewal, the award of a permit or renewal for a shorter duration than we believed was otherwise required by law, or burdensome terms and conditions being imposed on our operations.  We may not be able to obtain new landfill sites or expand the permitted capacity of our landfills when necessary.  Obtaining new landfill sites is important to our expansion into new, non-exclusive solid waste markets and in our E&P waste business.  If we do not believe that we can obtain a landfill site in a non-exclusive market, we may choose not to enter that market.  Expanding existing landfill sites is important in those markets where the remaining lives of our landfills are relatively short.  We may choose to forego acquisitions and internal growth in these markets because increased volumes would further shorten the lives of these landfills.  Any of these circumstances could adversely affect our operating results. 

26

Our E&P waste business could be adversely affected by changes in laws regulating E&P waste.

We believe that the demand for our E&P waste services is directly related to the regulation of E&P waste. In particular, RCRA, which governs the disposal of solid and hazardous waste, currently exempts certain E&P wastes from classification as hazardous wastes. In recent years, proposals have been made to rescind this exemption from RCRA. If the exemption covering E&P wastes is repealed or modified, or if the regulations interpreting the rules regarding the treatment or disposal of this type of waste were changed, our operations could face significantly more stringent regulations, permitting requirements, and other restrictions, which could have a material adverse effect on our business.

Changes in laws or government regulations regarding hydraulic fracturing could increase our customers’ costs of doing business and reduce oil and gas production by our customers, which could adversely impact our business.

We do not conduct hydraulic fracturing operations, but we do provide treatment, recovery and disposal services with respect to the fluids used and wastes generated by our customers in such operations, which are often necessary to drill and complete new wells and maintain existing wells. Recently, there has been increased public concern regarding the alleged potential for hydraulic fracturing to adversely affect drinking water supplies, and proposals have been made to enact separate federal, state and local legislation that would increase the regulatory burden imposed on hydraulic fracturing. Bills and regulations have been proposed and/or adopted at the federal, state, and local levels that would regulate, restrict, or prohibit hydraulic fracturing operations or require the reporting and public disclosure of chemicals used in the hydraulic fracturing process. Additionally, the EPA is currently studying the environmental impacts of hydraulic fracturing, including the impacts resulting from the treatment and disposal of E&P wastes associated with the hydraulic fracturing process, which could result in increased regulation of hydraulic fracturing and new rules regarding the treatment and disposal of E&P wastes associated with fracturing.

If new federal, state, or local laws or regulations that significantly restrict hydraulic fracturing are adopted, such legal requirements could result in delays, eliminate certain drilling and injection activities, and make it more difficult or costly for our customers to perform fracturing. Any such regulations limiting or prohibiting hydraulic fracturing could reduce oil and natural gas E&P activities by our customers and, therefore, adversely affect our business. Such laws or regulations could also materially increase our costs of compliance and doing business by more strictly regulating how hydraulic fracturing wastes are handled or disposed. Conversely, any loosening of existing federal, state, or local laws or regulations regarding how such wastes are handled or disposed could adversely impact demand for our services.

Future changes in laws regulating the flow of solid waste in interstate commerce could adversely affect our operating results. 

Various state and local governments have enacted, or are considering enacting, laws and regulations that restrict the disposal within the jurisdiction of solid waste generated outside the jurisdiction. In addition, some state and local governments have promulgated, or are considering promulgating, laws and regulations which govern the flow of waste generated within their respective jurisdictions.  These “flow control” laws and regulations typically require that waste generated within the jurisdiction be directed to specified facilities for disposal or processing, which could limit or prohibit the disposal or processing of waste in our transfer stations and landfills. Such flow control laws and regulations could also require us to deliver waste collected by us within a particular jurisdiction to facilities not owned or controlled by us, which could increase our costs and reduce our revenues. In addition, such laws and regulations could require us to obtain additional costly licenses or authorizations to be deemed an authorized hauler or disposal facility.

Additionally, public interest and pressure from competing industry segments has caused some trade associations and environmental activists to seek enforcement of laws regulating the flow of solid waste that have not been recently enforced.  For example, see the discussion regarding the Solano County, California Measure E/Landfill Expansion Litigation under the “Legal Proceedings” section of Note 11 of our consolidated financial statements included in Item 8 of this report.  If successful, these groups may advocate for the enactment of similar laws in neighboring jurisdictions through local ballot initiatives or otherwise.  All such waste disposal laws and regulations are subject to judicial interpretation and review.  Court decisions, legislation, and state and local regulation in the waste disposal area could adversely affect our operations.  

Extensive and evolving environmental, health and safety laws and regulations may restrict our operations and growth and increase our costs. 

Existing environmental laws and regulations have become more stringently enforced in recent years.  In addition, our industry is subject to regular enactment of new or amended federal, state and local environmental and health and safety statutes, regulations and ballot initiatives, as well as judicial decisions interpreting these requirements, which have become more stringent over time.  Citizen suits brought pursuant to environmental laws have proliferated. We expect these trends to continue, which could lead to material increases in our costs for future environmental compliance. These requirements also impose substantial capital and operating costs and operational limitations on us and may adversely affect our business.  In addition, federal, state and local governments may change the rights they grant to, the restrictions they impose on, or the laws and regulations they enforce against, solid waste and E&P waste services companies. These changes could adversely affect our operations by restricting the way in which we manage storm water runoff, treat and dispose of E&P or other waste or our ability to operate and expand our business.

27

Governmental authorities and various interest groups have promoted laws and regulations that could limit greenhouse gas, or GHG, emissions due to concerns that GHGs are contributing to climate change.  The State of California has already adopted a climate change law, and other states in which we operate are considering similar actions. In addition, the EPA made an endangerment finding in 2009 allowing certain GHGs to be regulated under the CAA.  This finding allows the EPA to create regulations that will impact our operations – including imposing emission reporting, permitting, control technology installation, and monitoring requirements, although the materiality of the impacts will not be known until all regulations are finalized.  Regulation of GHG emissions from oil and natural gas E&P operations may also increase the costs to our customers of developing and producing hydrocarbons, and as a result, may have an indirect and adverse effect on the amount of oilfield waste delivered to our facilities by our customers. These statutes and regulations increase the costs of our operations, and future climate change statutes and regulations may have an impact as well.

Extensive regulations that govern the design, operation and closure of landfills may restrict our landfill operations or increase our costs of operating landfills.

If we fail to comply with state and federal regulations governing the design, operation, closure and financial assurance of MSW and E&P landfills, we could be required to undertake investigatory or remedial activities, curtail operations or close such landfills temporarily or permanently.  Future changes to these regulations may require us to modify, supplement or replace equipment or facilities at substantial costs.  If regulatory agencies fail to enforce these regulations vigorously or consistently, our competitors whose facilities are not forced to comply with the regulations may obtain an advantage over us.  Our financial obligations arising from any failure to comply with these regulations could harm our business and operating results.

Alternatives to landfill disposal may cause our revenues and operating results to decline.

Counties and municipalities in which we operate landfills may be required to formulate and implement comprehensive plans to reduce the volume of municipal solid waste deposited in landfills through waste planning, composting, recycling or other programs.  Some state and local governments prohibit the disposal of certain types of wastes, such as yard waste, at landfills.  Although such actions are useful to protect our environment, these actions, as well as the actions of our customers to reduce waste or seek disposal alternatives, have reduced and may in the future further reduce the volume of waste going to landfills in certain areas, which may affect our ability to operate our landfills at full capacity and could adversely affect our operating results.

ITEM 2. PROPERTIES

As of December 31, 2013, we owned 148 collection operations, 51 transfer stations, 33 MSW landfills, six E&P waste landfills, five non-MSW landfills, 36 recycling operations, five intermodal operations, 20 liquid E&P waste injection wells, 17 E&P waste treatment and recovery facilities and 20 oil recovery facilities, and operated, but did not own, an additional 15 transfer stations, nine MSW landfills, two non-MSW landfills and two intermodal operations, in 31 states.  Non-MSW landfills accept construction and demolition, industrial and other non-putrescible waste. We lease certain of the sites on which these facilities are located.  We lease various office facilities, including our corporate offices in The Woodlands, Texas, where we occupy approximately 53,000 square feet of space. We also maintain regional administrative offices in each of our segments.  We own various equipment, including waste collection and transportation vehicles, related support vehicles, double-stack rail cars, carts, containers, chassis and heavy equipment used in landfill, collection, transfer station, waste treatment and intermodal operations.  We believe that our existing facilities and equipment are adequate for our current operations.  However, we expect to make additional investments in property and equipment for expansion and replacement of assets in connection with future acquisitions.

ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS 

The following discussion should be read in conjunction with the “Selected Financial Data” included in Item 6 of this Annual Report on Form 10-K, our consolidated financial statements and the related notes included elsewhere in this report. 

Industry Overview

The municipal solid waste industry is a local and highly competitive business, requiring substantial labor and capital resources.  The participants compete for collection accounts primarily on the basis of price and, to a lesser extent, the quality of service, and compete for landfill business on the basis of tipping fees, geographic location and quality of operations.  The municipal solid waste industry has been consolidating and continues to consolidate as a result of a number of factors, including the increasing costs and complexity associated with waste management operations and regulatory compliance.  Many small independent operators and municipalities lack the capital resources, management, operating skills and technical expertise necessary to operate effectively in such an environment.  The consolidation trend has caused municipal solid waste companies to operate larger landfills that have complementary collection routes that can use company-owned disposal capacity.  Controlling the point of transfer from haulers to landfills has become increasingly important as landfills continue to close and disposal capacity moves further from collection markets. 

Generally, the most profitable operators within the municipal solid waste industry are those companies that are vertically integrated or enter into long-term collection contracts.  A vertically integrated operator will benefit from:  (1) the internalization of waste, which is bringing waste to a company-owned landfill; (2) the ability to charge third-party haulers tipping fees either at landfills or at transfer stations; and (3) the efficiencies gained by being able to aggregate and process waste at a transfer station prior to landfilling. 

The E&P waste services industry is regional in nature and is also highly fragmented, with acquisition opportunities available in several active natural resource basins. Competition for E&P waste comes primarily from smaller regional companies that utilize a variety of disposal methods and generally serve specific geographic markets. In addition, customers in many markets have the option of using internal disposal methods or outsourcing to another third-party disposal company. The principal competitive factors in this business include: gaining customer approval of treatment and disposal facilities; location of facilities in relation to customer activity; reputation; reliability of services; track record of environmental compliance; ability to accept multiple waste types at a single facility; and price. 

Executive Overview

We are an integrated municipal solid waste services company that provides solid waste collection, transfer, disposal and recycling services primarily in exclusive and secondary markets in the U.S. and a leading provider of non-hazardous exploration and production, or E&P, waste treatment, recovery and disposal services in several of the most active natural resource producing areas of the U.S. We also provide intermodal services for the rail haul movement of cargo and solid waste containers in the Pacific Northwest through a network of intermodal facilities.

We seek to avoid highly competitive, large urban markets and instead target markets where we can attain high market share either through exclusive contracts, vertical integration or asset positioning. In markets where waste collection services are provided under exclusive arrangements, or where waste disposal is municipally owned or funded or available at multiple municipal sources, we believe that controlling the waste stream by providing collection services under exclusive arrangements is often more important to our growth and profitability than owning or operating landfills.  We also target niche markets, like E&P waste treatment and disposal services, with similar characteristics and, we believe, higher comparative growth potential.

As of December 31, 2013, we served residential, commercial, industrial and E&P customers in 31 states:  Alabama, Alaska, Arizona, California, Colorado, Idaho, Illinois, Iowa, Kansas, Kentucky, Louisiana, Massachusetts, Michigan, Minnesota, Mississippi, Montana, Nebraska, Nevada, New Mexico, New York, North Carolina, North Dakota, Oklahoma, Oregon, South Carolina, South Dakota, Tennessee, Texas, Utah, Washington and Wyoming.  As of December 31, 2013, we owned or operated a network of 148 solid waste collection operations; 66 transfer stations; seven intermodal facilities, 36 recycling operations, 55 active MSW, E&P and/or non-MSW landfills, 20 E&P liquid waste injection wells, 17 E&P waste treatment and recovery facilities and 20 oil recovery facilities.

2013 Financial Performance

Operating Results 

Revenues in 2013 increased 16.1% to $1.93 billion from $1.66 billion in 2012, primarily as a result of the R360 acquisition. Solid waste revenues increased 5.2%, primarily due to internal growth. E&P revenues increased to $250.8 million from $59.8 million in 2012, primarily as a result of the R360 acquisition. Solid waste internal growth increased to 3.1% in 2013, from negative 0.1% in 2012.  Pricing growth was 0.3 percentage points lower than in 2012, due to lower core prices partially offset by higher surcharges. Increases in landfill volumes contributed to total volume growth increasing to 0.7% in 2013 from negative 2.1% in 2012, which reflected customer losses in that year. A smaller decrease in recycled commodity prices than in the prior year, coupled with lower volumes due to the closure of one of our recycling operations, resulted in recycling contributing negative 0.5% to internal growth in 2013, compared to negative 1.3% in 2012.

In 2013, adjusted earnings before interest, taxes, depreciation and amortization, or adjusted EBITDA, a non-GAAP financial measure (refer to page 58 of this report for a definition and reconciliation to Net income), increased 24.3% to $657.0 million, from $528.4 million in 2012.  As a percentage of revenue, adjusted EBITDA increased from 31.8% in 2012, to 34.1% in 2013.  This 2.3 percentage point increase was primarily attributable to an increased mix of higher margin solid waste disposal and E&P waste revenues. Adjusted net income attributable to Waste Connections, a non-GAAP financial measure (refer to page 59 of this report for a definition and reconciliation to Net income attributable to Waste Connections), in 2013 increased 17.9% to $221.8 million from $188.1 million in 2012.

Adjusted Free Cash Flow 

Net cash provided by operating activities increased 16.3% to $484.1 million in 2013, from $416.3 million in 2012, and capital expenditures increased from $153.5 million in 2012 to $209.9 million in 2013, an increase of $56.4 million, or 36.7%. This increase in capital expenditures was primarily due to pulling forward into 2013 capital expenditures from 2014 to take advantage of bonus depreciation tax benefits available in 2013, and the construction of a new E&P waste landfill.  Adjusted free cash flow, a non-GAAP financial measure (refer to page 57 of this report for a definition and reconciliation to Net cash provided by operating activities), increased 9.4% to $301.6 million in 2013, from $275.8 million in 2012.  Adjusted free cash flow as a percentage of revenues was 15.6% in 2013, compared to 16.6% in 2012.  This decrease as a percentage of revenues was primarily due to increased capital expenditures as noted above.

Return of Capital to Stockholders

In 2013, we returned $51.2 million to stockholders through cash dividends declared by our Board of Directors, which also increased the quarterly cash dividend by 15% from $0.10 to $0.115 per share of common stock in October 2013. Our Board of Directors intends to review the quarterly dividend during the fourth quarter of each year, with a long-term objective of increasing the amount of the dividend. In 2013, we did not complete any share repurchases, as we deployed excess free cash flow to reduce the increased amount of outstanding debt incurred in connection with the R360 acquisition completed in October 2012. We expect the amount of capital we return to stockholders through stock repurchases to vary depending on our financial condition and results of operations, capital structure, the amount of cash we deploy on acquisitions, the market price of our common stock, and overall market conditions. We cannot assure you as to the amounts or timing of future stock repurchases or dividends. We have the ability under our senior revolving credit facility, term loan facility, and Master Note Purchase Agreement to repurchase our common stock and pay dividends provided we maintain specified financial ratios.

Capital Position 

We target a leverage ratio, as defined in our credit facility, of approximately 2.75x total debt to EBITDA.  We deployed $64.2 million during 2013 for acquisitions from operating cash flow, and we paid down over $165 million in debt. As a result, our leverage ratio improved to approximately 3.1x during 2013.

Critical Accounting Estimates and Assumptions

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses and related disclosures of contingent assets and liabilities in the consolidated financial statements.  As described by the SEC, critical accounting estimates and assumptions are those that may be material due to the levels of subjectivity and judgment necessary to account for highly uncertain matters or the susceptibility of such matters to change, and that have a material impact on the financial condition or operating performance of a company.  Such critical accounting estimates and assumptions are applicable to our reportable segments.  Based on this definition, we believe the following are our critical accounting estimates.

35

Insurance liabilities.  We maintain high deductible or self-insured retention insurance policies for automobile, general, employer’s, environmental, cyber, employment practices and directors’ and officers’ liability as well as for employee group health insurance, property insurance and workers’ compensation.  We carry umbrella policies for certain types of claims to provide excess coverage over the underlying policies and per incident deductibles or self-insured retentions.  Our insurance accruals are based on claims filed and estimates of claims incurred but not reported and are developed by our management with assistance from our third-party actuary and third-party claims administrator.  The insurance accruals are influenced by our past claims experience factors, which have a limited history, and by published industry development factors.  If we experience insurance claims or costs above or below our historically evaluated levels, our estimates could be materially affected.  The frequency and amount of claims or incidents could vary significantly over time, which could materially affect our self-insurance liabilities.  Additionally, the actual costs to settle the self-insurance liabilities could materially differ from the original estimates and cause us to incur additional costs in future periods associated with prior year claims. 

Income taxes.  Deferred tax assets and liabilities are determined based on differences between the financial reporting and income tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse.  If our judgment and estimates concerning assumptions made in calculating our expected future income tax rates are incorrect, our deferred tax assets and liabilities would change.  Based on our net deferred tax liability balance at December 31, 2013, each 0.1 percentage point change to our expected future income tax rate would change our net deferred tax liability balance and income tax expense by approximately $1.2 million. 

Accounting for landfills.  We recognize landfill depletion expense as airspace of a landfill is consumed.  Our landfill depletion rates are based on the remaining disposal capacity at our landfills, considering both permitted and probable expansion airspace.  We calculate the net present value of our final capping, closure and post-closure commitments by estimating the total obligation in current dollars, inflating the obligation based upon the expected date of the expenditure and discounting the inflated total to its present value using a credit-adjusted risk-free rate.  Any changes in expectations that result in an upward revision to the estimated undiscounted cash flows are treated as a new liability and are inflated and discounted at rates reflecting current market conditions.  Any changes in expectations that result in a downward revision (or no revision) to the estimated undiscounted cash flows result in a liability that is inflated and discounted at rates reflecting the market conditions at the time the cash flows were originally estimated.  This policy results in our final capping, closure and post-closure liabilities being recorded in “layers.”  The resulting final capping, closure and post-closure obligation is recorded on the balance sheet along with an offsetting addition to site costs, which is amortized to depletion expense as the remaining landfill airspace is consumed.  Interest is accreted on the recorded liability using the corresponding discount rate.  The accounting methods discussed below require us to make certain estimates and assumptions.  Changes to these estimates and assumptions could have a material effect on our financial condition and results of operations.  Any changes to our estimates are applied prospectively. 

Landfill development costs.  Landfill development costs include the costs of acquisition, construction associated with excavation, liners, site berms, groundwater monitoring wells, gas recovery systems and leachate collection systems.  We estimate the total costs associated with developing each landfill site to its final capacity.  Total landfill costs include the development costs associated with expansion airspace.  Expansion airspace is described below.  Landfill development costs depend on future events and thus actual costs could vary significantly from our estimates.  Material differences between estimated and actual development costs may affect our cash flows by increasing our capital expenditures and thus affect our results of operations by increasing our landfill depletion expense. 

Final capping, closure and post-closure obligations.  We accrue for estimated final capping, closure and post-closure maintenance obligations at the landfills we own, and five of the six landfills that we operate, but do not own, under life-of-site agreements.  We could have additional material financial obligations relating to final capping, closure and post-closure costs at other disposal facilities that we currently own or operate or that we may own or operate in the future.  Our discount rate assumption for purposes of computing 2013 and 2012 “layers” for final capping, closure and post-closure obligations was 5.75% for each year, which reflects our long-term cost of borrowing as of the end of 2012 and 2011.  Our inflation rate assumption was 2.5% for the years ended December 31, 2013 and 2012.  Significant reductions in our estimates of the remaining lives of our landfills or significant increases in our estimates of the landfill final capping, closure and post-closure maintenance costs could have a material adverse effect on our financial condition and results of operations.  Additionally, changes in regulatory or legislative requirements could increase our costs related to our landfills, resulting in a material adverse effect on our financial condition and results of operations. 

36

We own two landfills for which the prior owners are obligated to reimburse us for certain costs we incur for final capping, closure and post-closure activities on the portion of the landfill utilized by the prior owners.  We accrue the prior owner’s portion of the final capping, closure and post-closure obligation within the balance sheet classification of Other long-term liabilities, and a corresponding receivable from the prior owner in long-term Other assets. 

Disposal capacity.  Our internal and third-party engineers perform surveys at least annually to estimate the remaining disposal capacity at our landfills.  Our landfill depletion rates are based on the remaining disposal capacity, considering both permitted and probable expansion airspace, at the landfills that we own and at certain landfills that we operate, but do not own, under life-of-site agreements.  Our landfill depletion rate is based on the term of the operating agreement at our operated landfill that has capitalized expenditures.  Expansion airspace consists of additional disposal capacity being pursued through means of an expansion that has not yet been permitted.  Expansion airspace that meets the following criteria is included in our estimate of total landfill airspace:  

1) whether the land where the expansion is being sought is contiguous to the current disposal site, and we either own the expansion property or have rights to it under an option, purchase, operating or other similar agreement; 

2) whether total development costs, final capping costs, and closure/post-closure costs have been determined; 

3) whether internal personnel have performed a financial analysis of the proposed expansion site and have determined that it has a positive financial and operational impact; 

4) whether internal personnel or external consultants are actively working to obtain the necessary approvals to obtain the landfill expansion permit; and 

5) whether we consider it probable that we will achieve the expansion (for a pursued expansion to be considered probable, there must be no significant known technical, legal, community, business or political restrictions or similar issues existing that we believe are more likely than not to impair the success of the expansion). 

We may be unsuccessful in obtaining permits for expansion disposal capacity at our landfills.  In such cases, we will charge the previously capitalized development costs to expense.  This will adversely affect our operating results and cash flows and could result in greater landfill depletion expense being recognized on a prospective basis. 

We periodically evaluate our landfill sites for potential impairment indicators.  Our judgments regarding the existence of impairment indicators are based on regulatory factors, market conditions and operational performance of our landfills.  Future events could cause us to conclude that impairment indicators exist and that our landfill carrying costs are impaired.  Any resulting impairment loss could have a material adverse effect on our financial condition and results of operations. 

Goodwill and indefinite-lived intangible assets testing.  Goodwill and indefinite-lived intangible assets are tested for impairment on at least an annual basis in the fourth quarter of the year.  In the first step of testing for goodwill impairment, we estimate the fair value of each reporting unit, which we have determined to be our three geographic operating segments and our E&P segment, and compare the fair value with the carrying value of the net assets assigned to each reporting unit.  If the fair value of a reporting unit is greater than the carrying value of the net assets, including goodwill, assigned to the reporting unit, then no impairment results.  If the fair value is less than its carrying value, then we would perform a second step and determine the fair value of the goodwill.  In this second step, the fair value of goodwill is determined by deducting the fair value of a reporting unit’s identifiable assets and liabilities from the fair value of the reporting unit as a whole, as if that reporting unit had just been acquired and the purchase price were being initially allocated.  If the fair value of the goodwill is less than its carrying value for a reporting unit, an impairment charge would be recorded to earnings in our Consolidated Statements of Net Income.  In testing indefinite-lived intangible assets for impairment, we compare the estimated fair value of each indefinite-lived intangible asset to its carrying value.  If the fair value of the indefinite-lived intangible asset is less than its carrying value, an impairment charge would be recorded to earnings in our Consolidated Statements of Net Income. 

To determine the fair value of each of our reporting units as a whole and each indefinite-lived intangible asset, we use discounted cash flow analyses, which require significant assumptions and estimates about the future operations of each reporting unit and the future discrete cash flows related to each indefinite-lived intangible asset.  Significant judgments inherent in these analyses include the determination of appropriate discount rates, the amount and timing of expected future cash flows and growth rates.  The cash flows employed in our 2013 discounted cash flow analyses were based on ten-year financial forecasts, which in turn were based on the 2014 annual budget developed internally by management.  These forecasts reflect operating profit margins that were consistent with 2013 results and perpetual revenue growth rates of 3.2%.  Our discount rate assumptions are based on an assessment of our weighted average cost of capital which approximated 5.4%.  In assessing the reasonableness of our determined fair values of our reporting units, we evaluate our results against our current market capitalization. 

In addition, we would evaluate a reporting unit for impairment if events or circumstances change between annual tests indicating a possible impairment.  Examples of such events or circumstances include the following: 

· a significant adverse change in legal factors or in the business climate; 

37

· an adverse action or assessment by a regulator; 

· a more likely than not expectation that a segment or a significant portion thereof will be sold; or 

· the testing for recoverability of a significant asset group within the segment. 

We did not record an impairment charge as a result of our goodwill and indefinite-lived intangible assets impairment tests in 2013 and 2012.

Business Combination Accounting.  We recognize, separately from goodwill, the identifiable assets acquired and liabilities assumed at their estimated acquisition date fair values. We measure and recognize goodwill as of the acquisition date as the excess of: (a) the aggregate of the fair value of consideration transferred, the fair value of any noncontrolling interest in the acquiree (if any) and the acquisition date fair value of our previously held equity interest in the acquiree (if any), over (b) the fair value of net assets acquired and liabilities assumed. At the acquisition date, we measure the fair values of all assets acquired and liabilities assumed that arise from contractual contingencies.  We measure the fair values of all noncontractual contingencies if, as of the acquisition date, it is more likely than not that the contingency will give rise to an asset or liability. 

General 

Our revenues consist mainly of fees we charge customers for collection, transfer, recycling and disposal of non-hazardous solid waste and treatment, recovery and disposal of non-hazardous E&P waste.  Our collection business also generates revenues from the sale of recyclable commodities, which have significant variability.  A large part of our collection revenues comes from providing residential, commercial and industrial services.  We frequently perform these services under service agreements, municipal contracts or franchise agreements with governmental entities.  Our existing franchise agreements and most of our existing municipal contracts give us the exclusive right to provide specified waste services in the specified territory during the contract term.  These exclusive arrangements are awarded, at least initially, on a competitive bid basis and subsequently on a bid or negotiated basis.  We also provide residential collection services on a subscription basis with individual households. 

We typically determine the prices of our solid waste collection services by the collection frequency and level of service, route density, volume, weight and type of waste collected, type of equipment and containers furnished, the distance to the disposal or processing facility, the cost of disposal or processing, and prices charged by competitors for similar services.  The terms of our contracts sometimes limit our ability to pass on price increases.  Long-term solid waste collection contracts often contain a formula, generally based on a published price index, that automatically adjusts fees to cover increases in some, but not all, operating costs, or that limit increases to less than 100% of the increase in the applicable price index. 

We charge transfer station and landfill customers a tipping fee on a per ton and/or per yard basis for disposing of their solid waste at our transfer stations and landfill facilities.  Many of our transfer station and landfill customers have entered into one to ten year disposal contracts with us, most of which provide for annual indexed price increases. 

Our revenues from E&P waste treatment and disposal consist mainly of fees that we charge for the treatment of liquid and solid waste derived from the production of oil and natural gas. We also generate income from the transportation of waste to the disposal facility in certain markets and the sale of reclaimed oil, roadbase and processed and treated waters.

Our revenues from recycling services consist of selling recyclable materials (including compost, cardboard, office paper, plastic containers, glass bottles and ferrous and aluminum metals) collected from our residential customers and at our recycling processing operations to third parties for processing before resale. 

Our revenues from intermodal services consist mainly of fees we charge customers for the movement of cargo and solid waste containers between our intermodal facilities.  We also generate revenue from the storage, maintenance and repair of cargo and solid waste containers and the sale or lease of containers and chassis. 

38

No single contract or customer accounted for more than 10% of our total revenues at the consolidated or reportable segment level during the periods presented.  The table below shows for the periods indicated our total reported revenues attributable to services provided (dollars in thousands).

Cost of operations includes labor and benefits, tipping fees paid to third-party disposal facilities, vehicle and equipment maintenance, workers’ compensation, vehicle and equipment insurance, insurance and employee group health claims expense, third-party transportation expense, fuel, the cost of materials we purchase for recycling, district and state taxes and host community fees and royalties.  Our significant costs of operations in 2013 were labor, third-party disposal and transportation, vehicle and equipment maintenance, taxes and fees, insurance and fuel.  We use a number of programs to reduce overall cost of operations, including increasing the use of automated routes to reduce labor and workers’ compensation exposure, utilizing comprehensive maintenance and health and safety programs, and increasing the use of transfer stations to further enhance internalization rates.  We carry high-deductible or self-insured retention insurance for automobile liability, general liability, employer’s liability, environmental liability, cyber liability, employment practices liability and directors’ and officers’ liability as well as for employee group health claims, property and workers’ compensation.  If we experience insurance claims or costs above or below our historically evaluated levels, our estimates could be materially affected. 

Selling, general and administrative, or SG&A, expense includes management, sales force, clerical and administrative employee compensation and benefits, legal, accounting and other professional services, acquisition expenses, bad debt expense and rent expense for our corporate headquarters. 

Depreciation expense includes depreciation of equipment and fixed assets over their estimated useful lives using the straight-line method.  Depletion expense includes depletion of landfill site costs and total future development costs as remaining airspace of the landfill is consumed.  Remaining airspace at our landfills includes both permitted and probable expansion airspace.  Amortization expense includes the amortization of finite-lived intangible assets, consisting primarily of long-term franchise agreements and contracts, customer lists and non-competition agreements, over their estimated useful lives using the straight-line method.  Goodwill and indefinite-lived intangible assets, consisting primarily of certain perpetual rights to provide solid waste collection and transportation services in specified territories, are not amortized. 

We capitalize some third-party expenditures related to development projects, such as legal, engineering and interest expenses.  We expense all third-party and indirect acquisition costs, including third-party legal and engineering expenses, executive and corporate overhead, public relations and other corporate services, as we incur them.  We charge against net income any unamortized capitalized expenditures and advances (net of any portion that we believe we may recover, through sale or otherwise) that may become impaired, such as those that relate to any operation that is permanently shut down and any landfill development project that we believe will not be completed.  We routinely evaluate all capitalized costs, and expense those related to projects that we believe are not likely to succeed.  For example, if we are unsuccessful in our attempts to obtain or defend permits that we are seeking or have been awarded to operate or expand a landfill, we will no longer generate anticipated income from the landfill and we will be required to expense in a future period the amount of capitalized expenditures related to the landfill or expansion project, less the recoverable value of the property and other amounts recovered.

Years Ended December 31, 2013 and 2012 

Revenues.  Total revenues increased $267.2 million, or 16.1%, to $1.929 billion for the year ended December 31, 2013, from $1.662 billion for the year ended December 31, 2012.

During the year ended December 31, 2013, incremental revenue growth from the R360 acquisition was $186.0 million. All other acquisitions closed during, or subsequent to, the year ended December 31, 2012, increased revenues by approximately $38.2 million. Operations divested during, or subsequent to, the year ended December 31, 2012, decreased revenues by approximately $5.4 million. 

During the year ended December 31, 2013, the net increase in prices charged to our customers was $46.7 million, consisting of $42.2 million of core price increases and $4.5 million of fuel, materials and environmental surcharges. 

During the year ended December 31, 2013, volume increases in our existing business increased revenues by $13.7 million. The increase in volume was primarily attributable to increases in landfill MSW volumes, landfill special waste projects and roll off collection resulting from increased construction and general economic activity in our markets, partially offset by the loss of commercial and residential collection revenues under the terminated Madera County contract and by declines in commercial collection primarily attributable to service level declines with existing customers and a reduction in customer counts due to competition in our markets.

During the year ended December 31, 2013, decreased recyclable commodity volumes in our Eastern segment, the closure of a recycling operation in our Western segment and decreased recyclable commodity prices, primarily due to decreased overseas demand for recyclable commodities, decreased revenues by $7.9 million.

Other revenues decreased by $4.1 million during the year ended December 31, 2013, primarily due to a decrease in cargo volume at our intermodal operations due primarily to the loss of a large intermodal customer.

Income Tax Provision.  Income taxes increased $19.5 million, or 18.5%, to $124.9 million for the year ended December 31, 2013, from $105.4 million for the year ended December 31, 2012, as a result of increased pre-tax income. 

Our effective tax rates for the years ended December 31, 2013 and 2012, were 38.9% and 39.8%, respectively.  

During the year ended December 31, 2012, income tax expense and our effective tax rate were increased by $2.6 million and 1.0 percentage points, respectively, associated with an adjustment in deferred tax liabilities resulting from changes in the geographical apportionment of our state income taxes primarily due to the R360 acquisition, and $1.1 million and 0.4 percentage points, respectively, due to $2.9 million of the $3.6 million equity-based compensation granted to certain executive officers, incurred at the time the executives agreed to modifications to their employment contracts, being non-deductible expenses.

Additionally, the reconciliation of the income tax provision to the 2011 federal and state tax returns, which were filed during 2012, decreased tax expense by $1.7 million and reduced our effective tax rate by 0.6 percentage points for the year ended December 31, 2012. The reconciliation of the income tax provision to the 2012 federal and state tax returns, which were filed during 2013, decreased our tax expense by $0.8 million and reduced our effective tax rate by 0.3 percentage points for the year ended December 31, 2013.

During the year ended December 31, 2012, the net increase in prices charged to our customers was $47.5 million, consisting of $45.1 million of core price increases and $2.4 million of fuel, materials and environmental surcharges. 

Volume decreases in our existing business during the year ended December 31, 2012, decreased revenues by approximately $31.4 million.  The net decreases in volume were primarily attributable to decreases in landfill MSW volumes, due primarily to the decision to forego low-priced tonnage from one large hauler at one of our large landfills;  lower landfill special waste volumes, due primarily to a decrease in large non-recurring projects; decreased commercial collection revenue, due primarily to service level declines with existing customers and a reduction in customer counts due to competition in our markets; and decreased roll off collection activity, due primarily to construction slowdowns affecting our markets, partially offset by increased E&P waste treatment and disposal activity, due to increased drilling activity.

Decreased recyclable commodity prices during the year ended December 31, 2012, partially offset by increased recyclable commodity volumes collected, decreased revenues by $20.0 million. The decrease in recyclable commodity prices was primarily due to decreased overseas demand for recyclable commodities.

Other revenues increased by $1.3 million during the year ended December 31, 2012, primarily due to an increase in cargo volume at our intermodal operations.

Segment Reporting

Our Chief Operating Decision Maker evaluates operating segment profitability and determines resource allocations based on several factors, of which the primary financial measure is EBITDA. We define EBITDA as earnings before interest, taxes, depreciation, amortization, gain (loss) on disposal of assets, loss on prior office leases and other income (expense).  EBITDA is not a measure of operating income, operating performance or liquidity under GAAP and may not be comparable to similarly titled measures reported by other companies.  Our management uses EBITDA in the evaluation of segment operating performance as it is a profit measure that is generally within the control of the operating segments.  

Prior to October 2012, we managed our operations through three geographic operating segments (Western, Central and Eastern), which were also our reportable segments. In October 2012, as a result of the R360 acquisition described in Note 3 of our consolidated financial statements included in Item 8 of this report, we realigned our reporting structure and created a fourth operating segment, the E&P segment, which includes the majority of our E&P waste treatment and disposal operations. As a result, our three geographic operating segments and our E&P segment comprise our reportable segments. Additionally, in January 2013, we transferred an E&P operation in Louisiana, owned by us prior to the R360 acquisition, from our Central segment to our E&P segment. Each operating segment is responsible for managing several vertically integrated operations, which are comprised of districts.  The segment information presented herein reflects the addition of the new E&P segment and the transfer of our E&P operation in Louisiana to the E&P segment. Under the current structure, our Western segment is comprised of operating locations in Alaska, California, Idaho, Montana, Nevada, Oregon, Washington and western Wyoming; our Central segment is comprised of operating locations in Arizona, Colorado, Kansas, Louisiana, Minnesota, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, Utah and eastern Wyoming; and our Eastern segment is comprised of operating locations in Alabama, Illinois, Iowa, Kentucky, Massachusetts, Michigan, Mississippi, New York, North Carolina, South Carolina and Tennessee. The E&P segment is comprised of our E&P operations in Louisiana, New Mexico, North Dakota, Oklahoma, Texas, Wyoming and along the Gulf of Mexico.

Segment EBITDA

EBITDA in our Western segment increased $20.1 million, or 8.8%, to $249.5 million for the year ended December 31, 2013, from $229.4 million for the year ended December 31, 2012.  The increase was primarily due to income generated from acquisitions closed during, or subsequent to, the year ended December 31, 2012, price increases charged to our customers, increased landfill volumes, decreased rail transportation expenses at our intermodal operations resulting from the decline in intermodal cargo volume, decreased expenses associated with the cost of recyclable commodities due to declines in commodity values, decreased auto and workers’ compensation expense under our high deductible insurance program due primarily to a reduction in projected losses on open auto and workers’ compensation claims and decreased bad debt expense due to improved collection results, partially offset by decreased recyclable commodity revenue, decreased intermodal revenue, increased taxes on revenues resulting from higher collection and landfill revenues, increased third-party trucking and transportation expenses resulting from the increase in landfill volumes, increased direct and administrative labor expenses resulting from employee pay increases and additional personnel needed to support the segment’s growth and increased cash incentive compensation expense resulting from the achievement of certain financial targets.

EBITDA in our Western segment decreased $3.5 million, or 1.5%, to $229.4 million for the year ended December 31, 2012, from $232.9 million for the year ended December 31, 2011.  The decrease was primarily due to decreased recyclable commodity revenue, decreased collection and landfill MSW and special waste volumes, increased allocation of expenses from corporate due to an increase in budgeted revenues, increased leachate disposal expenses due to regulatory changes increasing the cost of disposal at one of our landfills, increased disposal expenses due to changes in the disposal internalization of collected volumes in certain markets and an increase in disposal rates at certain municipally owned landfills we utilize for disposal, increased third-party trucking and transportation expenses due to increased transfer station volumes in certain markets and increased property rent expenses associated with new facilities leases in our collection and intermodal operations, partially offset by price increases charged to our customers, decreased taxes on revenues, decreased expenses associated with the cost of recyclable commodities, decreased professional fees associated with legal matters, decreased expenses for uncollectible accounts receivable due primarily to higher expenses in the prior year resulting from a large customer filing for bankruptcy and income generated from acquisitions closed during, or subsequent to, the year ended December 31, 2011.

48

EBITDA in our Central segment increased $19.7 million, or 13.6%, to $164.8 million for the year ended December 31, 2012, from $145.1 million for the year ended December 31, 2011.  The increase was primarily due to increased E&P waste treatment and disposal revenue at our MSW landfills that also receive E&P waste, price increases charged to our customers and income generated from acquisitions closed during, or subsequent to, the year ended December 31, 2011, partially offset by decreased collection and landfill MSW volumes, decreased recyclable commodity revenue, increased allocation of expenses from corporate due to an increase in budgeted revenues, increased third-party trucking and transportation expenses due to increased transfer station volumes in certain markets, increased truck, container and equipment maintenance and repair expenses due to increases in the prices for parts and services and variability in the timing and severity of major equipment repairs, increased diesel fuel expenses due to an increase in the market price for diesel fuel and increased labor expenses due to employee pay increases.

EBITDA in our Eastern segment increased $7.2 million, or 7.1%, to $108.2 million for the year ended December 31, 2013, from $101.0 million for the year ended December 31, 2012.  The increase was primarily due to price increases charged to our customers, increased landfill volumes, decreased expenses associated with the cost of recyclable commodities due to declines in commodity value and a decrease in recyclable commodity volume, decreased auto and workers’ compensation expense under our high deductible insurance program due primarily to a reduction in projected losses on open auto and workers’ compensation claims and decreased allocation of expenses from corporate due to a decrease in the allocation rate, partially offset by decreased recyclable commodity revenue, decreased residential and commercial collection volumes, increased diesel fuel expenses due primarily to the net impact of the expiration of a prior year fuel hedge in which the diesel fuel fixed price under the hedge agreement was less than the diesel fuel retail price and increased expenses for uncollectible accounts receivable primarily due to receivables from one large customer that were deemed uncollectible.

EBITDA in our Eastern segment increased $5.7 million, or 6.0%, to $101.0 million for the year ended December 31, 2012, from $95.3 million for the year ended December 31, 2011.  The increase was primarily due to price increases charged to our customers and income generated from acquisitions closed during, or subsequent to, the year ended December 31, 2011 and decreased expenses for uncollectible accounts receivable due primarily to the collection of balances in 2012 that were deemed uncollectible in 2011, partially offset by decreased collection and landfill MSW volumes, decreased recyclable commodity revenue, increased allocation of expenses from corporate due to an increase in budgeted revenues, increased diesel fuel expenses due to an increase in the market price for diesel fuel, increased third-party trucking and transportation expenses resulting from increased special waste landfill volumes, increased truck, container and equipment maintenance and repair expenses due to increases in the prices for parts and services and variability in the timing and severity of major equipment repairs, increased auto and workers’ compensation expense under our high deductible insurance program due to an increase in projected losses on open claims and increased labor expenses due to employee pay increases.

EBITDA in our E&P segment increased $87.4 million, or 369.6%, to $111.1 million for the year ended December 31, 2013, from $23.7 million for the year ended December 31, 2012.  The increase was primarily attributable to EBITDA generated from the R360 acquisition.

EBITDA in our E&P segment increased $16.7 million, or 239.3%, to $23.7 million for the year ended December 31, 2012, from $7.0 million for the year ended December 31, 2011.  The increase was primarily attributable to EBITDA generated from the R360 acquisition.

EBITDA at Corporate improved $10.9 million, to a loss of $0.2 million for the year ended December 31, 2013, from a loss of $11.1 million for the year ended December 31, 2012.  The lower loss was due to decreased relocation expenses primarily associated with the relocation of our corporate headquarters from Folsom, California to The Woodlands, Texas, which was substantially completed in 2012, a decrease in total equity-based compensation expense primarily resulting from a grant in 2012 of $3.6 million of immediately vested restricted stock units to certain executive officers at the time the executives agreed to modifications to their employment contracts, a decrease in direct acquisition expenses due to a decline in acquisition activity and an increase in corporate overhead expense allocations due primarily to a full year allocation of expenses to our new E&P segment, partially offset by an increase in cash incentive compensation expense resulting from the achievement of certain financial targets, an increase in equity-based compensation expense associated with our annual recurring grant of restricted stock units to our personnel and an increase in professional fee expenses due primarily to increased expenses for external accounting, tax and information technology services.

EBITDA at Corporate decreased $16.6 million, or 300.6%, to a loss of $11.1 million for the year ended December 31, 2012, from income of $5.5 million for the year ended December 31, 2011.  The decrease was primarily due to an increase in direct acquisition expenses due to an increase in acquisition activity, increased deferred compensation expense resulting from deferred compensation liabilities to employees being increased as a result of increases in the market value of investments to which employee deferred compensation balances are tracked, expenses associated with the relocation of our corporate headquarters from Folsom, California to The Woodlands, Texas, and increased equity-based compensation expense, including a grant of immediately vested restricted stock units to certain executive officers at the time the executives agreed to modifications to their employment contracts.

a) an increase in cash resulting from an increase in accrued liabilities of $6.1 million due primarily to an increase in accrued interest due to the timing of interest payments on our notes and term loan facility, an increase in accrued cash incentive compensation expense resulting from the achievement of certain financial targets and an increase in accrued payroll due to our payroll pay cycle resulting in one additional day of accrual at December 31, 2013;

b) an increase in cash resulting from a $4.2 million increase in other long term liabilities due primarily to increased deferred compensation plan liabilities resulting from employee contributions and plan earnings;

c) an increase in cash resulting from a $1.7 million decrease in prepaid expenses and other current assets due primarily to a decrease in prepaid income taxes;

4) An increase in our provision for deferred taxes of $9.0 million due primarily to an increase in the tax deductibility of goodwill as a result of goodwill recorded from acquisitions closed during the year ended December 31, 2012, as well as other tax deductible timing differences associated with depreciation; less

5) A decrease in equity-based compensation expense of $1.9 million due to a grant of $3.6 million of immediately vested restricted stock units to certain executive officers at the time the executives agreed to modifications to their employment contracts during the year ended December 31, 2012, partially offset by a $1.7 million increase associated with our annual grant of restricted stock units to our personnel during the year ended December 31, 2013; less

6) An increase in payment of contingent consideration recorded in earnings of $5.1 million due primarily to the final contingent consideration payout resulting from the completion of an earnings target for the 2012 acquisition of SKB Environmental, Inc., or SKB, exceeding the fair value of the contingent consideration liability recorded at the acquisition close date.

For the year ended December 31, 2012, net cash provided by operating activities was $416.3 million.  For the year ended December 31, 2011, net cash provided by operating activities was $388.2 million.  The $28.1 million increase was due primarily to the following: 

1) A decrease in net income of $6.5 million, adjusted for an increase in cash flows from operating assets and liabilities, net of effects from acquisitions, of $22.7 million to cash provided by operating assets and liabilities of $14.1 million for the year ended December 31, 2012, from cash used by operating assets and liabilities of $8.6 million for the year ended December 31, 2011.  The significant components of the $14.1 million in net cash inflows from changes in operating assets and liabilities for the year ended December 31, 2012, include the following:

a) an increase in cash resulting from an increase in accrued liabilities of $7.8 million due primarily to increased liabilities for auto and workers’ compensation claims, increased liabilities for payroll related expenses and increased liabilities for employee benefit claims;

4) A decrease in our provision for deferred taxes of $21.3 million due primarily to the recognition during the year ended December 31, 2011, of tax benefits associated with a change in our tax method for deducting depreciation expense for certain landfills as well as other tax deductible timing differences associated with depreciation. 

As of December 31, 2013, we had a working capital deficit of $16.5 million, including cash and equivalents of $13.6 million.  Our working capital deficit decreased $38.6 million from a deficit of $55.1 million at December 31, 2012, including cash and equivalents of $23.2 million.  To date, we have experienced no loss or lack of access to our cash or cash equivalents; however, we can provide no assurances that access to our cash and cash equivalents will not be impacted by adverse conditions in the financial markets.  Our strategy in managing our working capital is generally to apply the cash generated from our operations that remains after satisfying our working capital and capital expenditure requirements, along with stock repurchase and dividend programs, to reduce the unhedged portion of our indebtedness under our credit facility and to minimize our cash balances.

Investing Activities Cash Flows

Net cash used in investing activities decreased $1.483 billion to $251.0 million for the year ended December 31, 2013, from $1.734 billion for the year ended December 31, 2012.  The significant components of the decrease include the following:

2) A decrease in cash flows from proceeds from common stock offerings of $369.6 million, net, due to the sale during the year ended December 31, 2012, of 12,000,000 shares of our common stock in a public offering;

3) An increase in payment of contingent consideration recorded at close of $11.4 million due primarily to the payout in 2013 of the fair value of the contingent consideration liability recorded at the close date for the 2012 acquisition of SKB resulting from the achievement of an earnings target, partially offset by the 2012 payout of the fair value of the contingent consideration liability recorded at the close date for the 2012 R360 acquisition; and

4) An increase in cash dividends paid of $6.7 million due to an increase in our dividend rate to an annual total of $0.415 per share in 2013, from an annual total of $0.37 per share in 2012, and an increase in our total common shares outstanding; less

5) A decrease in payments to repurchase our common stock of $18.6 million due to no shares being repurchased during the year ended December 31, 2013.

Net cash provided by financing activities increased $1.313 billion to $1.328 billion for the year ended December 31, 2012, from $14.6 million for the year ended December 31, 2011.  The significant components of the increase include the following: 

1) An increase in cash flows from the proceeds from our common stock offering of $369.6 million, net, due to the March 2012 sale of 12,000,000 shares of our common stock in a public offering;

2) A decrease in payments to repurchase our common stock of $98.2 million due to less shares repurchased;

3) An increase in net long-term borrowings of $867.4 million due primarily to funding $1.275 billion of the purchase price for the R360 acquisition; partially offset by the repayment of debt with the $369.6 million of proceeds from our common stock offering; less

4) An increase in cash dividends paid of $8.9 million due to an increase in our dividend rate to an annual total of $0.37 per share in 2012 and an increase in our total common shares outstanding; less

5) An increase in payments of contingent consideration of $12.0 million due to the payout of $8.4 million of contingent consideration assumed in the R360 acquisition and the payout of $4.1 million of contingent consideration related to the achievement of earnings targets for acquisitions closed in 2011 and 2010; partially offset by the payout of $0.5 million of contingent consideration in 2011 related to the achievement of earnings targets for an acquisition closed in 2010; less

6) A decrease in proceeds from option and warrant exercises of $1.1 million due to a decrease in the number of options and warrants exercised in the year ended December 31, 2012.

Our business is capital intensive.  Our capital requirements include acquisitions and capital expenditures for landfill cell construction, landfill development, landfill closure activities and intermodal facility construction in the future.

Our Board of Directors has authorized a common stock repurchase program for the repurchase of up to $1.2 billion of our common stock through December 31, 2014. Under the program, stock repurchases may be made in the open market or in privately negotiated transactions from time to time at management’s discretion. The timing and amounts of any repurchases will depend on many factors, including our capital structure, the market price of the common stock and overall market conditions. As of each of December 31, 2013 and 2012, we had repurchased in aggregate 39.9 million shares of our common stock at an aggregate cost of $784.0 million.  As of December 31, 2013, the remaining maximum dollar value of shares available for purchase under the program was approximately $416.0 million.  No shares were repurchased under the program during the year ended December 31, 2013.

Our Board of Directors authorized the initiation of a quarterly cash dividend in October 2010 and has increased it on an annual basis. Cash dividends of $51.2 million and $44.5 million were paid during the years ended December 31, 2013 and 2012, respectively. In October 2013, our Board of Directors authorized an increase to our regular quarterly cash dividend of $0.015, from $0.10 to $0.115 per share. We cannot assure you as to the amounts or timing of future dividends. 

We made $209.9 million in capital expenditures during the year ended December 31, 2013. We expect to make capital expenditures between $180 million and $190 million in 2014 in connection with our existing business.  We intend to fund our planned 2014 capital expenditures principally through cash on hand, internally generated funds and borrowings under our credit facility.  In addition, we may make substantial additional capital expenditures in acquiring MSW and E&P waste businesses. If we acquire additional landfill disposal facilities, we may also have to make significant expenditures to bring them into compliance with applicable regulatory requirements, obtain permits or expand our available disposal capacity.  We cannot currently determine the amount of these expenditures because they will depend on the number, nature, condition and permitted status of any acquired landfill disposal facilities.  We believe that our cash and equivalents, credit facility and the funds we expect to generate from operations will provide adequate cash to fund our working capital and other cash needs for the foreseeable future.  However, disruptions in the capital and credit markets could adversely affect our ability to draw on our credit facility or raise other capital.  Our access to funds under the credit facility is dependent on the ability of the banks that are parties to the facility to meet their funding commitments.  Those banks may not be able to meet their funding commitments if they experience shortages of capital and liquidity or if they experience excessive volumes of borrowing requests within a short period of time.

We are a well-known seasoned issuer with an effective shelf registration statement on Form S-3 filed in February 2012, which registers an unspecified amount of debt and equity securities, including preferred securities, warrants, stockholder rights and units. We may in the future issue debt or equity securities under our shelf registration statement or in private placements from time to time on an opportunistic basis, dependent upon market conditions and available pricing. We expect to use the proceeds from any such offerings for general corporate purposes, including repaying, redeeming or repurchasing debt, acquisitions of additional assets or businesses, capital expenditures and increasing our working capital.

On October 25, 2012, we completed the acquisition of the business of R360, through the acquisition of all of R360’s principal operating subsidiaries, for total cash consideration of approximately $1.34 billion. Additionally, we assumed approximately $9.3 million of outstanding R360 debt and $37.3 million of contingent consideration. The R360 acquisition was funded with available cash and with borrowings of $475 million under our senior revolving credit facility and $800 million under our uncollateralized term loan facility with Bank of America, N.A. and the other banks and lending institutions party thereto, as lenders, Bank of America, N.A., as administrative agent, and JPMorgan Chase Bank, N.A. and Wells Fargo Bank, National Association, as co-syndication agents. The term loan is subject to principal payments which commenced at $10.0 million per quarter in April 2013, increase to $20.0 million per quarter in April 2014 and increase again to $30.0 million per quarter in April 2015. A final principal payment of $390.0 million is due upon maturity of the term loan on October 25, 2017. The borrowings under the term loan facility are required to be used only to fund the R360 acquisition pursuant to the R360 purchase and sale agreement and to pay fees and expenses incurred in connection with the R360 acquisition and our entry into the term loan facility.

Outstanding amounts on the term loan facility can be either base rate loans or LIBOR loans. At December 31, 2013 and 2012, all amounts outstanding under the term loan facility were in LIBOR loans which bear interest at the LIBOR rate plus the applicable LIBOR margin (approximately 2.04% and 2.21% at December 31, 2013 and 2012, respectively).  The LIBOR rate is determined by the administrative agent in a customary manner as described in the term loan agreement. The applicable margins under the term loan agreement vary depending on our leverage ratio, as defined in the term loan agreement, as amended, and range from 1.375% per annum to 2.375% per annum for LIBOR loans. As of December 31, 2013 and 2012, the margin was 1.875% and 2.0%, respectively, for LIBOR loans.  Borrowings under the term loan facility are not collateralized.

The term loan facility contains representations and warranties and places certain business, financial and operating restrictions on us relating to, among other things, indebtedness, liens, investments, mergers, consolidation and disposition of assets, sale and leaseback transactions, restricted payments and redemptions, burdensome agreements, business activities, transactions with affiliates, prepayments of indebtedness and accounting changes. During the continuance of an event of default, the lenders may take a number of actions, including declaring the entire amount then outstanding under the term loan facility due and payable. The term loan facility contains cross-defaults if we default on the senior revolving credit facility, the Master Note Purchase Agreement or certain other debt. The term loan facility requires that we maintain specified quarterly leverage and interest coverage ratios. The required leverage ratio cannot exceed 3.50x total debt to earnings before interest, taxes, depreciation and amortization, or EBITDA. The required interest coverage ratio must be at least 2.75x total interest expense to earnings before interest and taxes, or EBIT. As of December 31, 2013 and 2012, our leverage ratio was 3.08x and 3.28x, respectively. As of December 31, 2013 and 2012, our interest coverage ratio was 6.33x and 6.88x, respectively.  We expect to be in compliance with all applicable covenants in the term loan facility for the next 12 months.

We have a $1.2 billion senior revolving credit facility, or the credit facility, with a syndicate of banks for which Bank of America, N.A. acts as administrative agent.  As of December 31, 2013, $727.1 million was outstanding under the credit facility, exclusive of outstanding standby letters of credit of $75.2 million. As of December 31, 2012, $787.0 million was outstanding under the credit facility, exclusive of outstanding standby letters of credit of $87.3 million. 

Under the credit facility, swing line loans may be issued at our request in an aggregate amount not to exceed a $25.0 million sublimit and there is no maximum amount of standby letters of credit that can be issued under the credit facility; however, the issuance of swing line loans and standby letters of credit both reduce the amount of total borrowings available.  The credit facility requires us to pay a commitment fee ranging from 0.150% per annum to 0.275% per annum of the unused portion of the facility.  The borrowings under the credit facility bear interest, at our option, at either the base rate plus the applicable base rate margin on base rate loans and swing line loans, or the LIBOR rate plus the applicable margin on LIBOR loans.  The base rate for any day is a fluctuating rate per annum equal to the highest of: (1) the federal funds rate plus one half of one percent (0.500%); (2) the LIBOR rate plus one percent (1.000%), and (3) the rate of interest in effect for such day as publicly announced from time to time by Bank of America as its “prime rate.” The LIBOR rate is determined by the administrative agent pursuant to a formula in the credit agreement. The applicable margins under the credit facility vary depending on our leverage ratio, as defined in the credit agreement, and range from 1.125% per annum to 1.750% per annum for LIBOR loans and 0.125% per annum to 0.750% per annum for base rate loans.  The credit facility matures in May 2018.  The borrowings under the credit facility are not collateralized.  The credit agreement contains representations, warranties, covenants and events of default, including a change of control event of default and limitations on incurrence of indebtedness and liens, new lines of business, mergers, transactions with affiliates and restrictive payments. During the continuance of an event of default, the lenders may take a number of actions, including declaring the entire amount then outstanding under the credit agreement due and payable. The credit facility contains cross-defaults if we default on the term loan facility, the Master Note Purchase Agreement or certain other debt. The credit facility requires that we maintain specified quarterly leverage and interest coverage ratios. The required leverage ratio cannot exceed 3.50x total debt to EBITDA. The required interest coverage ratio must be at least 2.75x total interest expense to EBIT. As of December 31, 2013 and 2012, our leverage ratio was 3.08x and 3.28x, respectively. As of December 31, 2013 and 2012, our interest coverage ratio was 6.33x and 6.88x, respectively. We expect to be in compliance with all applicable covenants under the credit facility for the next 12 months. We use the credit facility for acquisitions, capital expenditures, working capital, standby letters of credit and general corporate purposes.

On July 15, 2008, we entered into a Master Note Purchase Agreement with certain accredited institutional investors pursuant to which we issued and sold to the investors at a closing on October 1, 2008, $175 million of senior uncollateralized notes due October 1, 2015, or the 2015 Notes, in a private placement.  The 2015 Notes bear interest at the fixed rate of 6.22% per annum with interest payable in arrears semi-annually on April 1 and October 1 beginning on April 1, 2009, and with principal payable at the maturity of the 2015 Notes on October 1, 2015. 

On October 26, 2009, we entered into a First Supplement to the Master Note Purchase Agreement with certain accredited institutional investors pursuant to which we issued and sold to the investors on that date $175 million of senior uncollateralized notes due November 1, 2019, or the 2019 Notes, in a private placement.  The 2019 Notes bear interest at the fixed rate of 5.25% per annum with interest payable in arrears semi-annually on May 1 and November 1 beginning on May 1, 2010, and with principal payable at the maturity of the 2019 Notes on November 1, 2019. 

On April 1, 2011, we entered into a Second Supplement to Master Note Purchase Agreement with certain accredited institutional investors, pursuant to which we issued and sold to the investors on that date $250 million of senior uncollateralized notes at fixed interest rates with interest payable in arrears semi-annually on October 1 and April 1 beginning on October 1, 2011 in a private placement. Of these notes, $100 million will mature on April 1, 2016 with an annual interest rate of 3.30% (the “2016 Notes”), $50 million will mature on April 1, 2018 with an annual interest rate of 4.00% (the “2018 Notes”), and $100 million will mature on April 1, 2021 with an annual interest rate of 4.64% (the “2021 Notes”).

The 2015 Notes, 2016 Notes, 2018 Notes, 2019 Notes, and 2021 Notes (collectively, the “Senior Notes”) are uncollateralized obligations and rank equally in right of payment with each of the Senior Notes, the obligations under our senior uncollateralized revolving credit facility and the obligations under our term loan facility. The Senior Notes are subject to representations, warranties, covenants and events of default.  The Master Note Purchase Agreement contains cross-defaults if we default on the credit facility, the term loan facility or certain other debt. The Master Note Purchase Agreement requires that we maintain specified quarterly leverage and interest coverage ratios. The required leverage ratio cannot exceed 3.75x total debt to EBITDA. The required interest coverage ratio must be at least 2.75x total interest expense to EBIT. As of December 31, 2013 and 2012, our leverage ratio was 3.08x and 3.28x, respectively. As of December 31, 2013 and 2012, our interest coverage ratio was 6.33x and 6.88x, respectively. We expect to be in compliance with all applicable covenants under the Senior Notes for the next 12 months.

Upon the occurrence of an event of default, payment of the Senior Notes may be accelerated by the holders of the respective notes.  The Senior Notes may also be prepaid at any time in whole or from time to time in any part (not less than 5% of the then-outstanding principal amount) by us at par plus a make-whole amount determined in respect of the remaining scheduled interest payments on the Senior Notes, using a discount rate of the then current market standard for United States treasury bills plus 0.50%.  In addition, we will be required to offer to prepay the Senior Notes upon certain changes in control.

We may issue additional series of senior uncollateralized notes, including floating rate notes, pursuant to the terms and conditions of the Master Note Purchase Agreement, as amended, provided that the purchasers of the Senior Notes shall not have any obligation to purchase any additional notes issued pursuant to the Master Note Purchase Agreement and the aggregate principal amount of the outstanding notes and any additional notes issued pursuant to the Master Note Purchase Agreement shall not exceed $1.250 billion. We currently have $600 million of Notes outstanding under the Master Note Purchase Agreement.

As of December 31, 2013, we had the following contractual obligations (in thousands): 

	Payments Due by Period

Long-term debt payments include:

1) $727.1 million in principal payments due May 2018 related to our credit facility.  We may elect to draw amounts on our credit facility in either base rate loans or LIBOR loans. At December 31, 2013, all amounts outstanding under the credit facility were in LIBOR loans, which bear interest at the LIBOR rate plus applicable LIBOR margin (approximately 1.67% at December 31, 2013), and swing line loans, which bear interest at the base rate plus applicable base rate margin (approximately 3.75% at December 31, 2013. As of December 31, 2013, our credit facility allowed us to borrow up to $1.2 billion.

2) $700.0 million in principal payments related to our term loan facility.  Outstanding amounts on the term loan facility can be either base rate loans or LIBOR loans. At December 31, 2013, all amounts outstanding under the term loan facility were in LIBOR loans, which bear interest at the LIBOR rate plus the applicable LIBOR margin (approximately 2.04% at December 31, 2013).  Our term loan facility matures on October 25, 2017.

3) $175.0 million in principal payments due 2015 related to our 2015 Notes.  Holders of the 2015 Notes may require us to purchase their notes in cash at a purchase price of 100% of the principal amount of the 2015 Notes plus accrued and unpaid interest, if any, upon a change in control, as defined in the Master Note Purchase Agreement.  The 2015 Notes bear interest at a rate of 6.22%.

4) $100.0 million in principal payments due 2016 related to our 2016 Notes.  Holders of the 2016 Notes may require us to purchase their notes in cash at a purchase price of 100% of the principal amount of the 2016 Notes plus accrued and unpaid interest, if any, upon a change in control, as defined in the Master Note Purchase Agreement.  The 2016 Notes bear interest at a rate of 3.30%.

5) $50.0 million in principal payments due 2018 related to our 2018 Notes.  Holders of the 2018 Notes may require us to purchase their notes in cash at a purchase price of 100% of the principal amount of the 2018 Notes plus accrued and unpaid interest, if any, upon a change in control, as defined in the Master Note Purchase Agreement.  The 2018 Notes bear interest at a rate of 4.00%.

55

6) $175.0 million in principal payments due 2019 related to our 2019 Notes.  Holders of the 2019 Notes may require us to purchase their notes in cash at a purchase price of 100% of the principal amount of the 2019 Notes plus accrued and unpaid interest, if any, upon a change in control, as defined in the Master Note Purchase Agreement.  The 2019 Notes bear interest at a rate of 5.25%.

7) $100.0 million in principal payments due 2021 related to our 2021 Notes.  Holders of the 2021 Notes may require us to purchase their notes in cash at a purchase price of 100% of the principal amount of the 2021 Notes plus accrued and unpaid interest, if any, upon a change in control, as defined in the Master Note Purchase Agreement.  The 2021 Notes bear interest at a rate of 4.64%.

8) $33.0 million in principal payments related to our tax-exempt bonds, which bear interest at variable rates (between 0.08% and 0.16%) at December 31, 2013.  The tax-exempt bonds have maturity dates ranging from 2014 to 2033. 

9) $12.8 million in principal payments related to our notes payable to sellers and other third parties.  Our notes payable to sellers and other third parties bear interest at rates between 2.5% and 10.9% at December 31, 2013, and have maturity dates ranging from 2014 to 2036. 

The following assumptions were made in calculating cash interest payments: 

1) We calculated cash interest payments on the credit facility using the LIBOR rate plus the applicable LIBOR margin at December 31, 2013.  We assumed the credit facility is paid off when it matures in May 2018. 

2) We calculated cash interest payments on the term loan facility using the LIBOR rate plus the applicable LIBOR margin at December 31, 2013.  

3) We calculated cash interest payments on our interest rate swaps using the stated interest rate in the swap agreement less the LIBOR rate through the earlier expiration of the term of the swaps or the term of the credit facility.

Contingent consideration payments include $55.6 million recorded as liabilities in our consolidated financial statements at December 31, 2013, and $17.7 million of future interest accretion on the recorded obligations.

The estimated final capping, closure and post-closure expenditures presented above are not inflated.

	Amount of Commitment Expiration Per Period

Unrecorded Obligations(1)	Total		Less Than 1 Year		1 to 3 Years		3 to 5 Years		Over 5 Years
Operating leases	$	148,581	$	18,343	$	31,230	$	23,805	$	75,203
Unconditional purchase obligations		16,089		16,089		-		-		-

(1) We are party to operating lease agreements and unconditional purchase obligations as discussed in Note 11 to the consolidated financial statements.  These lease agreements and purchase obligations are established in the ordinary course of our business and are designed to provide us with access to facilities and products at competitive, market-driven prices.  At December 31, 2013, our unconditional purchase obligations consisted of multiple fixed-price fuel purchase contracts under which we have 4.6 million gallons remaining to be purchased for a total of $16.1 million, plus taxes and transportation costs upon delivery.  The current fuel purchase contracts expire on or before December 31, 2014.  These arrangements have not materially affected our financial position, results of operations or liquidity during the year ended December 31, 2013, nor are they expected to have a material impact on our future financial position, results of operations or liquidity. 

We have obtained standby letters of credit as discussed in Note 7 to the consolidated financial statements and financial surety bonds as discussed in Note 11 to the consolidated financial statements.  These standby letters of credit and financial surety bonds are generally obtained to support our financial assurance needs and landfill and E&P operations.  These arrangements have not materially affected our financial position, results of operations or liquidity during the year ended December 31, 2013, nor are they expected to have a material impact on our future financial position, results of operations or liquidity. 

From time to time, we evaluate our existing operations and their strategic importance to us.  If we determine that a given operating unit does not have future strategic importance, we may sell or otherwise dispose of those operations.  Although we believe our reporting units would not be impaired by such dispositions, we could incur losses on them.

Non-GAAP Financial Measures

Adjusted Free Cash Flow

We present adjusted free cash flow, a non-GAAP financial measure, supplementally because it is widely used by investors as a valuation and liquidity measure in the solid waste industry.  Management uses adjusted free cash flow as one of the principal measures to evaluate and monitor the ongoing financial performance of our operations.  We define adjusted free cash flow as net cash provided by operating activities, plus proceeds from disposal of assets, plus or minus change in book overdraft, plus excess tax benefit associated with equity-based compensation, less capital expenditures for property and equipment and distributions to noncontrolling interests.  We further adjust this calculation to exclude the effects of items management believes impact the ability to assess the operating performance of our business. This measure is not a substitute for, and should be used in conjunction with, GAAP liquidity or financial measures.  Other companies may calculate adjusted free cash flow differently.  Our adjusted free cash flow for the years ended December 31, 2013, 2012 and 2011, are calculated as follows (amounts in thousands): 

	Years Ended December 31,
	2013			2012			2011

Adjusted free cash flow	$	301,579		$	275,759		$	254,792

(a)   Reflects the addback of acquisition-related payments for contingent consideration that were recorded as expenses in earnings and a component of cash flow from operating activities as the amounts paid exceeded the fair value of the contingent consideration recorded at the acquisition date.

(b)   Reflects the addback of third-party expenses and reimbursable advances to employees associated with the relocation of our corporate headquarters from California to Texas.

(c)   Reflects the addback for the payment to terminate the remaining lease obligation of our former headquarters in Folsom, California.

(d)   The aggregate tax effect of the adjustments in footnotes (b) and (c) is calculated based on the applied tax rates for the respective periods.

Adjusted EBITDA

We present adjusted EBITDA, a non-GAAP financial measure, supplementally because it is widely used by investors as a performance and valuation measure in the solid waste industry.  Management uses adjusted EBITDA as one of the principal measures to evaluate and monitor the ongoing financial performance of our operations.  We define adjusted EBITDA as net income, plus income tax provision, plus interest expense, plus depreciation and amortization expense, plus closure and post-closure accretion expense, plus or minus any loss or gain on disposal of assets, plus other expense, less other income.  We further adjust this calculation to exclude the effects of items management believes impact the ability to assess the operating performance of our business.  This measure is not a substitute for, and should be used in conjunction with, GAAP financial measures.  Other companies may calculate adjusted EBITDA differently.  Our adjusted EBITDA for the years ended December 31, 2013, 2012 and 2011, are calculated as follows (amounts in thousands): 

	Years Ended December 31,
	2013		2012			2011
Net income	$	196,005	$	159,660		$	166,171

Adjusted EBITDA	$	657,002	$	528,419		$	489,613

(a) Reflects the addback of the loss on prior office leases resulting primarily from the relocation of our corporate headquarters from California to Texas.

(b) Reflects the addback of acquisition-related transaction and severance costs.

(c) Reflects the addback of costs associated with the relocation of our corporate headquarters from California to Texas.

(d) Reflects the addback of equity compensation expense incurred at the time our named executive officers’ employment contracts were modified.

(e) Reflects the elimination of a gain from an arbitration award.

Adjusted Net Income and Adjusted Net Income per Diluted Share

We present adjusted net income and adjusted net income per diluted share, both non-GAAP financial measures, supplementally because they are widely used by investors as a valuation measure in the solid waste industry. Management uses adjusted net income and adjusted net income per diluted share as one of the principal measures to evaluate and monitor the ongoing financial performance of our operations. We provide adjusted net income to exclude the effects of items management believes impact the comparability of operating results between periods. Adjusted net income has limitations due to the fact that it excludes items that have an impact on our financial condition and results of operations. Adjusted net income and adjusted net income per diluted share are not a substitute for, and should be used in conjunction with, GAAP financial measures. Other companies may calculate adjusted net income and adjusted net income per diluted share differently.  Our adjusted net income and adjusted net income per diluted share for the years ended December 31, 2013, 2012 and 2011, are calculated as follows (amounts in thousands, except per share amounts):

	Years Ended December 31,
	2013			2012			2011

Inflation

Other than volatility in fuel prices and labor costs in certain markets, inflation has not materially affected our operations in recent years.  Consistent with industry practice, many of our contracts allow us to pass through certain costs to our customers, including increases in landfill tipping fees and, in some cases, fuel costs.  Therefore, we believe that we should be able to increase prices to offset many cost increases that result from inflation in the ordinary course of business.  However, competitive pressures or delays in the timing of rate increases under our contracts may require us to absorb at least part of these cost increases, especially if cost increases exceed the average rate of inflation.  Management's estimates associated with inflation have an impact on our accounting for landfill liabilities.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK 

In the normal course of business, we are exposed to market risk, including changes in interest rates and prices of certain commodities.  We use hedge agreements to manage a portion of our risks related to interest rates and fuel prices.  While we are exposed to credit risk in the event of non-performance by counterparties to our hedge agreements, in all cases such counterparties are highly rated financial institutions and we do not anticipate non-performance.  We do not hold or issue derivative financial instruments for trading purposes.  We monitor our hedge positions by regularly evaluating the positions at market and by performing sensitivity analyses over the unhedged fuel and variable rate debt positions. 

At December 31, 2013, our derivative instruments included three interest rate swap agreements that effectively fix the interest rate on the applicable notional amounts of our variable rate debt as follows (dollars in thousands): 

Date Entered	Notional Amount		Fixed Interest Rate Paid*			Variable Interest Rate Received	Effective Date	Expiration Date
March 2009	$	175,000		2.85	%	1-month LIBOR	February 2011	February 2014
August 2011	$	150,000		0.80	%	1-month LIBOR	April 2012	January 2015
December 2011	$	175,000		1.60	%	1-month LIBOR	February 2014	February 2017

* plus applicable margin. 

Under derivatives and hedging guidance, the interest rate swap agreements are considered cash flow hedges for a portion of our variable rate debt, and we apply hedge accounting to account for these instruments.  The notional amounts and all other significant terms of the swap agreements are matched to the provisions and terms of the variable rate debt being hedged. 

We have performed sensitivity analyses to determine how market rate changes will affect the fair value of our unhedged floating rate debt.  Such an analysis is inherently limited in that it reflects a singular, hypothetical set of assumptions.  Actual market movements may vary significantly from our assumptions.  Fair value sensitivity is not necessarily indicative of the ultimate cash flow or earnings effect we would recognize from the assumed market rate movements.  We are exposed to cash flow risk due to changes in interest rates with respect to the unhedged floating rate balances owed at December 31, 2013 and 2012, of $1.128 billion and $1.298 billion, respectively, including floating rate debt under our credit facility, term loan facility and floating rate municipal bond obligations.  A one percentage point increase in interest rates on our variable-rate debt as of December 31, 2013 and 2012, would decrease our annual pre-tax income by approximately $11.3 million and $13.0 million, respectively.  All of our remaining debt instruments are at fixed rates, or effectively fixed under the interest rate swap agreements described above; therefore, changes in market interest rates under these instruments would not significantly impact our cash flows or results of operations, subject to counterparty default risk. 

The market price of diesel fuel is unpredictable and can fluctuate significantly.  We purchase approximately 31.5 million gallons of fuel per year; therefore, a significant increase in the price of fuel could adversely affect our business and reduce our operating margins.  To manage a portion of this risk, we periodically enter into fuel hedge agreements related to forecasted diesel fuel purchases. 

At December 31, 2013, our derivative instruments included one fuel hedge agreement as follows: 

Date Entered	Notional Amount (in gallons per month)		Diesel Rate Paid Fixed (per gallon)		Diesel Rate Received Variable	Effective Date	Expiration Date
June 2012		300,000	$	3.60	DOE Diesel Fuel Index*	January 2014	December 2015

*If the national U.S. on-highway average price for a gallon of diesel fuel (“average price”), as published by the Department of Energy, exceeds the contract price per gallon, we receive the difference between the average price and the contract price (multiplied by the notional number of gallons) from the counterparty.  If the average price is less than the contract price per gallon, we pay the difference to the counterparty. 

Under derivatives and hedging guidance, the fuel hedge is considered a cash flow hedge for a portion of our forecasted diesel fuel purchases, and we apply hedge accounting to account for this instrument. 

60

We have performed sensitivity analyses to determine how market rate changes will affect the fair value of our unhedged diesel fuel purchases.  Such an analysis is inherently limited in that it reflects a singular, hypothetical set of assumptions.  Actual market movements may vary significantly from our assumptions.  Fair value sensitivity is not necessarily indicative of the ultimate cash flow or earnings effect we would recognize from the assumed market rate movements.  For the year ending December 31, 2014, we expect to purchase approximately 31.5 million gallons of diesel fuel, of which 23.3 million gallons will be purchased at market prices, 3.6 million gallons will be purchased at prices that are fixed under our fuel hedge, and 4.6 million gallons will be purchased under our fixed price fuel purchase contracts.  With respect to the approximately 23.3 million gallons of unhedged diesel fuel we expect to purchase in 2014 at market prices, a $0.10 per gallon increase in the price of fuel over the year would decrease our pre-tax income during this period by approximately $2.3 million. 

We market a variety of recyclable materials, including cardboard, office paper, plastic containers, glass bottles and ferrous and aluminum metals.  We own and operate 36 recycling processing operations and sell other collected recyclable materials to third parties for processing before resale.  To reduce our exposure to commodity price risk with respect to recycled materials, we have adopted a pricing strategy of charging collection and processing fees for recycling volume collected from third parties.  In the event of a decline in recycled commodity prices, a 10% decrease in average recycled commodity prices from the average prices that were in effect during the year ended December 31, 2013 and 2012, would have had a $6.6 million and $7.3 million impact on revenues for the year ended December 31, 2013 and 2012, respectively.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of
Waste Connections, Inc.:

In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of Waste Connections, Inc. and its subsidiaries at December 31, 2013 and 2012, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2013 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedule listed in the accompanying index presents fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on criteria established in Internal Control - Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company's management is responsible for these financial statements and financial statement schedule, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements, on the financial statement schedule, and on the Company's internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. 

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

1. ORGANIZATION, BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

Organization and Business

Waste Connections, Inc. (“WCI” or the “Company”) was incorporated in Delaware on September 9, 1997, and commenced its operations on October 1, 1997, through the purchase of certain solid waste operations in the state of Washington.  The Company is an integrated municipal solid waste services company that provides solid waste collection, transfer, disposal and recycling services in mostly exclusive and secondary markets in the U.S. and a leading provider of non-hazardous exploration and production (“E&P”) waste treatment, recovery and disposal services in several of the most active natural resource producing areas of the U.S. The Company also provides intermodal services for the rail haul movement of cargo and solid waste containers in the Pacific Northwest.

Basis of Presentation 

These consolidated financial statements include the accounts of WCI and its wholly-owned and majority-owned subsidiaries.  The consolidated entity is referred to herein as the Company.  All significant intercompany accounts and transactions have been eliminated in consolidation. 

Cash Equivalents 

The Company considers all highly liquid investments with a maturity of three months or less at purchase to be cash equivalents.  As of December 31, 2013 and 2012, cash equivalents consisted of demand money market accounts.

Concentrations of Credit Risk 

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and equivalents, restricted assets and accounts receivable.  The Company maintains cash and 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’s restricted assets are invested primarily in U.S. government and agency securities. The Company has not experienced any losses related to its cash and equivalents or restricted asset 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.  The Company maintains allowances for losses based on the expected collectability of accounts receivable. 

Revenue Recognition and Accounts Receivable 

Revenues are recognized when persuasive evidence of an arrangement exists, the service has been provided, the price is fixed or determinable and collection is reasonably assured.  Certain customers are billed in advance and, accordingly, recognition of the related revenues is deferred until the services are provided.  In accordance with revenue recognition guidance, any tax assessed by a governmental authority that is directly imposed on a revenue-producing transaction between a seller and a customer is presented in the statements of net income on a net basis (excluded from revenues). 

The Company’s receivables are recorded when billed or accrued and represent claims against third parties that will be settled in cash.  The carrying value of the Company’s receivables, net of the allowance for doubtful accounts, represents their estimated net realizable value.  The Company estimates its allowance for doubtful accounts based on historical collection trends, type of customer such as municipal or non-municipal, the age of outstanding receivables 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 and the allowance is adjusted accordingly.  Past-due receivable balances are written off when the Company’s internal collection efforts have been unsuccessful in collecting the amount due. 

Property and Equipment 

Property and equipment are stated at cost.  Improvements or betterments, not considered to be maintenance and repair, which add new functionality or significantly extend the life of an asset are capitalized.  Third-party expenditures related to pending development projects, such as legal and engineering expenses, are capitalized.  Expenditures for maintenance and repair costs, including planned major maintenance activities, are charged to expense as incurred.  The cost of assets retired or otherwise disposed of and the related accumulated depreciation are eliminated from the accounts in the year of disposal.  Gains and losses resulting from disposals of property and equipment are recognized in the period in which the property and equipment is disposed.  Depreciation is computed using the straight-line method over the estimated useful lives of the assets or the lease term, whichever is shorter.

The estimated useful lives are as follows: 

Buildings	10 – 20 years
Leasehold and land improvements	3 – 10 years
Machinery and equipment	3 – 12 years
Rolling stock	2 – 10 years
Containers	5 – 12 years
Rail cars	20 years

Landfill Accounting

The Company utilizes the life cycle method of accounting for landfill costs.  This method applies the costs to be capitalized associated with acquiring, developing, closing and monitoring the landfills over the associated consumption of landfill capacity.  The Company utilizes the units of consumption method to amortize landfill development costs over the estimated remaining capacity of a landfill.  Under this method, the Company includes future estimated construction costs using current dollars, as well as costs incurred to date, in the amortization base.  When certain criteria are met, the Company includes expansion airspace, which has not been permitted, in the calculation of the total remaining capacity of the landfill. 

- Landfill development costs.  Landfill development costs include the costs of acquisition, construction associated with excavation, liners, site berms, groundwater monitoring wells, gas recovery systems and leachate collection systems.  The Company estimates the total costs associated with developing each landfill site to its final capacity.  This includes certain projected landfill site costs that are uncertain because they are dependent on future events and thus actual costs could vary significantly from estimates.  The total cost to develop a site to its final capacity includes amounts previously expended and capitalized, net of accumulated depletion, and projections of future purchase and development costs, liner construction costs, and operating construction costs.  Total landfill costs include the development costs associated with expansion airspace.  Expansion airspace is addressed below. 

- Final capping, closure and post-closure obligations.  The Company accrues for estimated final capping, closure and post-closure maintenance obligations at the landfills it owns and five of the six landfills that it operates, but does not own under life-of-site agreements.  Accrued final capping, closure and post-closure costs represent an estimate of the current value of the future obligation associated with final capping, closure and post-closure monitoring of non-hazardous solid waste landfills currently owned or operated under life-of-site agreements by the Company.  Final capping costs represent the costs related to installation of clay liners, drainage and compacted soil layers and topsoil constructed over areas of the landfill where total airspace capacity has been consumed.  Closure and post-closure monitoring and maintenance costs represent the costs related to cash expenditures yet to be incurred when a landfill facility ceases to accept waste and closes.  Accruals for final capping, closure and post-closure monitoring and maintenance requirements in the U.S. consider site inspection, groundwater monitoring, leachate management, methane gas control and recovery, and operating and maintenance costs to be incurred during the period after the facility closes.  Certain of these environmental costs, principally capping and methane gas control costs, are also incurred during the operating life of the site in accordance with the landfill operation requirements of Subtitle D and the air emissions standards.  Daily maintenance activities, which include many of these costs, are expensed as incurred during the operating life of the landfill.  Daily maintenance activities include leachate disposal; surface water, groundwater, and methane gas monitoring and maintenance; other pollution control activities; mowing and fertilizing the landfill final cap; fence and road maintenance; and third-party inspection and reporting costs.  Site specific final capping, closure and post-closure engineering cost estimates are prepared annually for landfills owned or landfills operated under life-of-site agreements by the Company for which it is responsible for final capping, closure and post-closure. 

The net present value of landfill final capping, closure and post-closure liabilities are calculated by estimating the total obligation in current dollars, inflating the obligation based upon the expected date of the expenditure and discounting the inflated total to its present value using a credit-adjusted risk-free rate.  Any changes in expectations that result in an upward revision to the estimated undiscounted cash flows are treated as a new liability and are inflated and discounted at rates reflecting current market conditions.  Any changes in expectations that result in a downward revision (or no revision) to the estimated undiscounted cash flows result in a liability that is inflated and discounted at rates reflecting the market conditions at the time the cash flows were originally estimated.  This policy results in the Company’s final capping, closure and post-closure liabilities being recorded in “layers.”  The Company’s discount rate assumption for purposes of computing 2013 and 2012 “layers” for final capping, closure and post-closure obligations was 5.75% for each year, which reflects the Company’s long-term cost of borrowing as of the end of 2012 and 2011.  The Company’s inflation rate assumption was 2.5% for the years ended December 31, 2013 and 2012.

In accordance with the accounting guidance on asset retirement obligations, the final capping, closure and post-closure liability is recorded on the balance sheet along with an offsetting addition to site costs which is amortized to depletion expense on a units-of-consumption basis as remaining landfill airspace is consumed.  The impact of changes determined to be changes in estimates, based on an annual update, is accounted for on a prospective basis.  Depletion expense resulting from final capping, closure and post-closure obligations recorded as a component of landfill site costs will generally be less during the early portion of a landfill’s operating life and increase thereafter.  Owned landfills and landfills operated under life-of-site agreements have estimated remaining lives, based on remaining permitted capacity, probable expansion capacity and projected annual disposal volumes, that range from approximately 5 to 200 years, with an average remaining life of approximately 42 years.  The costs for final capping, closure and post-closure obligations at landfills the Company owns or operates under life-of-site agreements are generally estimated based on interpretations of current requirements and proposed or anticipated regulatory changes. 

The estimates for landfill final capping, closure and post-closure costs consider when the costs would actually be paid and factor in inflation and discount rates.  Interest is accreted on the recorded liability using the corresponding discount rate.  When using discounted cash flow techniques, reliable estimates of market premiums may not be obtainable.  In the waste industry, there is no market for selling the responsibility for final capping, closure and post-closure obligations independent of selling the landfill in its entirety.  Accordingly, the Company does not believe that it is possible to develop a methodology to reliably estimate a market risk premium and has therefore excluded any such market risk premium from its determination of expected cash flows for landfill asset retirement obligations.  The possibility of changing legal and regulatory requirements and the forward-looking nature of these types of costs make any estimation or assumption less certain. 

The following is a reconciliation of the Company’s final capping, closure and post-closure liability balance from December 31, 2011 to December 31, 2013: 

Final capping, closure and post-closure liability at December 31, 2011	$	30,883
Adjustments to final capping, closure and post-closure liabilities		3,535
Liabilities incurred		2,926
Accretion expense associated with landfill obligations		2,581
Closure payments		(22	)
Assumption of closure liabilities from acquisitions		6,570
Final capping, closure and post-closure liability at December 31, 2012		46,473
Adjustments to final capping, closure and post-closure liabilities		(3,528	)
Liabilities incurred		4,668
Accretion expense associated with landfill obligations		2,749
Closure payments		(234	)
Final capping, closure and post-closure liability at December 31, 2013	$	50,128

The Adjustments to final capping, closure and post-closure liabilities for the year ended December 31, 2013, primarily consisted of increases in estimated airspace at some of the Company’s landfills at which expansions are being pursued or have been granted, decreases in estimated closure costs at some of the Company’s landfills and revisions in engineering estimates, partially offset by an increase in estimates of annual tonnage consumption at some of the Company’s landfills. The Adjustments to final capping, closure and post-closure liabilities for the year ended December 31, 2012, primarily consisted of increases in estimated closure costs and changes in timing of closure activities at some of the Company’s landfills, partially offset by a decrease in closure liabilities from third parties due to changes in timing of closure activities and reduced closure expenses. The final capping, closure and post-closure liability is included in Other long-term liabilities in the Consolidated Balance Sheets. The Company performs its annual review of its cost and capacity estimates in the first quarter of each year. 

At December 31, 2013, $33,466 of the Company’s restricted assets balance was for purposes of securing its performance of future final capping, closure and post-closure obligations.

- Disposal capacity.  The Company’s internal and third-party engineers perform surveys at least annually to estimate the remaining disposal capacity at its landfills.  This is done by using surveys and other methods to calculate, based on the terms of the permit, height restrictions and other factors, how much airspace is left to fill and how much waste can be disposed of at a landfill before it has reached its final capacity.  The Company’s landfill depletion rates are based on the remaining disposal capacity, considering both permitted and probable expansion airspace, at the landfills it owns, and certain landfills it operates, but does not own, under life-of-site agreements.  The Company’s landfill depletion rate is based on the term of the operating agreement at its operated landfill that has capitalized expenditures.  Expansion airspace consists of additional disposal capacity being pursued through means of an expansion that has not yet been permitted.  Expansion airspace that meets the following criteria is included in the estimate of total landfill airspace: 

1) whether the land where the expansion is being sought is contiguous to the current disposal site, and the Company either owns the expansion property or has rights to it under an option, purchase, operating or other similar agreement; 

2) whether total development costs, final capping costs, and closure/post-closure costs have been determined; 

3) whether internal personnel have performed a financial analysis of the proposed expansion site and have determined that it has a positive financial and operational impact; 

4) whether internal personnel or external consultants are actively working to obtain the necessary approvals to obtain the landfill expansion permit; and 

5) whether the Company considers it probable that the Company will achieve the expansion (for a pursued expansion to be considered probable, there must be no significant known technical, legal, community, business, or political restrictions or similar issues existing that the Company believes are more likely than not to impair the success of the expansion). 

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, as described below, 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 Company periodically evaluates its landfill sites for potential impairment indicators.  The Company’s judgments regarding the existence of impairment indicators are based on regulatory factors, market conditions and operational performance of its landfills.  Future events could cause the Company to conclude that impairment indicators exist and that its landfill carrying costs are impaired. 

Cell Processing Reserves

The Company records a cell processing reserve related to its E&P segment for certain locations in Louisiana and Texas for the estimated amount of expenses to be incurred upon the treatment and excavation of oilfield waste received. The cell processing reserve is the future cost to properly treat and dispose of existing waste within the cells at the various facilities. The reserve generally covers estimated costs to be incurred over a period of time up to 24 months, with the current portion representing costs estimated to be incurred in the next 12 months. The estimate is calculated based on current estimated volume in the cells, estimated percentage of waste treated, and historical average costs to treat and excavate the waste. The processing reserve represents the estimated costs to process the volumes of oilfield waste on-hand for which revenue has been recognized. At December 31, 2013 and 2012, the current portion of cell processing reserves was $7,013 and $6,442, respectively, which is included in Accrued liabilities in the Consolidated Balance Sheets. At December 31, 2013 and 2012, the long-term portion of cell processing reserves was $2,416 and $2,043, respectively, which is included in Other long-term liabilities in the Consolidated Balance Sheets.

Business Combination Accounting

The Company accounts for business combinations as follows: 

· The Company recognizes, separately from goodwill, the identifiable assets acquired and liabilities assumed at their estimated acquisition date fair values. The Company measures and recognizes goodwill as of the acquisition date as the excess of:  (a) the aggregate of the fair value of consideration transferred, the fair value of any noncontrolling interest in the acquiree (if any) and the acquisition date fair value of the Company’s previously held equity interest in the acquiree (if any), over (b) the fair value of net assets acquired and liabilities assumed. 

73

WASTE CONNECTIONS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(DOLLAR AMOUNTS IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)

· At the acquisition date, the Company measures the fair values of all assets acquired and liabilities assumed that arise from contractual contingencies.  The Company measures the fair values of all noncontractual contingencies if, as of the acquisition date, it is more likely than not that the contingency will give rise to an asset or liability. 

Finite-Lived Intangible Assets

The amounts assigned to franchise agreements, contracts and customer lists are being amortized on a straight-line basis over the expected term of the related agreements (ranging from 1 to 56 years).

Goodwill and Indefinite-Lived Intangible Assets 

The Company acquired indefinite-lived intangible assets in connection with certain of its acquisitions.  The amounts assigned to indefinite-lived intangible assets consist of the value of certain perpetual rights to provide solid waste collection and transportation services in specified territories and to operate exploration and production waste treatment and disposal facilities.  The Company measures and recognizes acquired indefinite-lived intangible assets at their estimated acquisition date fair values.  Indefinite-lived intangible assets are not amortized.  Goodwill represents the excess of:  (a) the aggregate of the fair value of consideration transferred, the fair value of any noncontrolling interest in the acquiree (if any) and the acquisition date fair value of the Company’s previously held equity interest in the acquiree (if any), over (b)  the fair value of assets acquired and liabilities assumed.  Goodwill and intangible assets, deemed to have indefinite lives, are subject to annual impairment tests as described below. 

Goodwill and indefinite-lived intangible assets are tested for impairment on at least an annual basis in the fourth quarter of the year.  In the first step of testing for goodwill impairment, the Company estimates the fair value of each reporting unit, which the Company has determined to be its three geographic operating segments and its E&P segment, and compares the fair value with the carrying value of the net assets assigned to each reporting unit.  If the fair value of a reporting unit is greater than the carrying value of the net assets, including goodwill, assigned to the reporting unit, then no impairment results.  If the fair value is less than the carrying value, then the Company would perform a second step and determine the fair value of the goodwill. In this second step, the fair value of goodwill is determined by deducting the fair value of a reporting unit’s identifiable assets and liabilities from the fair value of the reporting unit as a whole, as if that reporting unit had just been acquired and the purchase price were being initially allocated.  If the fair value of the goodwill is less than its carrying value for a reporting unit, an impairment charge would be recorded to earnings in the Company’s Consolidated Statements of Net Income.  In testing indefinite-lived intangible assets for impairment, the Company compares the estimated fair value of each indefinite-lived intangible asset to its carrying value.  If the fair value of the indefinite-lived intangible asset is less than its carrying value, an impairment charge would be recorded to earnings in the Company’s Consolidated Statements of Net Income. 

To determine the fair value of each of the Company’s reporting units as a whole and each indefinite-lived intangible asset, the Company uses discounted cash flow analyses, which require significant assumptions and estimates about the future operations of each reporting unit and the future discrete cash flows related to each indefinite-lived intangible asset. Significant judgments inherent in these analyses include the determination of appropriate discount rates, the amount and timing of expected future cash flows and growth rates.  The cash flows employed in the Company’s 2013 discounted cash flow analyses were based on ten-year financial forecasts, which in turn were based on the 2014 annual budget developed internally by management.  These forecasts reflect operating profit margins that were consistent with 2013 results and perpetual revenue growth rates of 3.2%. The Company’s discount rate assumptions are based on an assessment of the Company’s weighted average cost of capital which approximated 5.4%.  In assessing the reasonableness of the Company’s determined fair values of its reporting units, the Company evaluates its results against its current market capitalization. 

In addition, the Company would evaluate a reporting unit for impairment if events or circumstances change between annual tests indicating a possible impairment.  Examples of such events or circumstances include the following: 

· a significant adverse change in legal factors or in the business climate; 

· an adverse action or assessment by a regulator; 

· a more likely than not expectation that a segment or a significant portion thereof will be sold; or 

· the testing for recoverability of a significant asset group within the segment.

As a result of performing the tests for potential impairment of goodwill and indefinite-lived intangible assets, the Company determined that no impairment existed as of December 31, 2013 or 2012, and, therefore, there were no write-downs to any of its goodwill or indefinite-lived intangible assets.  

Impairments of Property, Plant and Equipment and Finite-Lived Intangible Assets 

Property, plant, equipment and finite-lived intangible assets are carried on the Company’s consolidated financial statements based on their cost less accumulated depreciation or amortization.  Finite-lived intangible assets consist of long-term franchise agreements, contracts, customer lists, permits and non-competition agreements.  The recoverability of these assets is tested whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. 

Typical indicators that an asset may be impaired include: 

· a significant adverse change in legal factors or in the business climate; 

· an adverse action or assessment by a regulator; 

· a more likely than not expectation that a segment or a significant portion thereof will be sold; or 

· the testing for recoverability of a significant asset group within a segment. 

If any of these or other indicators occur, a test of recoverability is performed by comparing the carrying value of the asset or asset group to its undiscounted expected future cash flows.  If the carrying value is in excess of the undiscounted expected future cash flows, impairment is measured by comparing the fair value of the asset to its carrying value.  Fair value is determined by an internally developed discounted projected cash flow analysis of the asset.  Cash flow projections are sometimes based on a group of assets, rather than a single asset.  If cash flows cannot be separately and independently identified for a single asset, the Company will determine whether an impairment has occurred for the group of assets for which the projected cash flows can be identified.  If the fair value of an asset is determined to be less than the carrying amount of the asset or asset group, an impairment in the amount of the difference is recorded in the period that the impairment indicator occurs.  Several impairment indicators are beyond the Company’s control, and whether or not they will occur cannot be predicted with any certainty.  Estimating future cash flows requires significant judgment and projections may vary from cash flows eventually realized.  There are other considerations for impairments of landfills, as described below. 

Landfills – There are certain indicators listed above that require significant judgment and understanding of the waste industry when applied to landfill development or expansion projects.  A regulator or court may deny or overturn a landfill development or landfill expansion permit application before the development or expansion permit is ultimately granted.  For example, see Note 11 for discussion of the Chaparral, New Mexico Landfill Permit Litigation, the Harper County, Kansas Landfill Permit Litigation and the Solano County, California Measure E/Landfill Expansion Litigation. Management may periodically divert waste from one landfill to another to conserve remaining permitted landfill airspace.  Therefore, certain events could occur in the ordinary course of business and not necessarily be considered indicators of impairment due to the unique nature of the waste industry. 

Restricted Assets 

Restricted assets held by trustees consist principally of funds deposited in connection with landfill final capping, closure and post-closure obligations and other financial assurance requirements.  Proceeds from these financing arrangements are directly deposited into trust funds, and the Company does not have the ability to utilize the funds in regular operating activities.  See Note 8 for further information on restricted assets.

Fair Value of Financial Instruments 

The Company’s financial instruments consist primarily of cash and equivalents, trade receivables, restricted assets, trade payables, debt instruments, contingent consideration obligations, interest rate swaps and a fuel hedge.  As of December 31, 2013 and 2012, the carrying values of cash and equivalents, trade receivables, restricted assets, trade payables and contingent consideration are considered to be representative of their respective fair values.  The carrying values of the Company’s debt instruments, excluding certain notes as listed in the table below, approximate their fair values as of December 31, 2013 and 2012, based on current borrowing rates, current remaining average life to maturity and borrower credit quality for similar types of borrowing arrangements, and are classified as Level 2 within the fair value hierarchy.  The carrying values and fair values of the Company’s debt instruments where the carrying values do not approximate their fair values as of December 31, 2013 and 2012, are as follows: 

	Carrying Value at December 31,				Fair Value* at December 31,
	2013		2012		2013		2012
6.22% Senior Notes due 2015	$	175,000	$	175,000	$	187,206	$	193,949
3.30% Senior Notes due 2016	$	100,000	$	100,000	$	102,066	$	103,068
4.00% Senior Notes due 2018	$	50,000	$	50,000	$	50,992	$	52,476
5.25% Senior Notes due 2019	$	175,000	$	175,000	$	185,037	$	195,584
4.64% Senior Notes due 2021	$	100,000	$	100,000	$	100,341	$	107,418

*Senior Notes are classified as Level 2 within the fair value hierarchy. Fair value is based on quotes of bonds with similar ratings in similar industries.

For details on the fair value of the Company’s interest rate swaps, fuel hedge and restricted assets, refer to Note 8. 

Derivative Financial Instruments

The Company recognizes all derivatives on the balance sheet at fair value.  All of the Company’s derivatives have been designated as cash flow hedges; therefore, the effective portion of the changes in the fair value of derivatives will be recognized in accumulated other comprehensive loss (“AOCL”) until the hedged item is recognized in earnings.  The ineffective portion of the changes in the fair value of derivatives will be immediately recognized in earnings.  The Company classifies cash inflows and outflows from derivatives within operating activities on the statement of cash flows. 

One of the Company’s objectives for utilizing derivative instruments is to reduce its exposure to fluctuations in cash flows due to changes in the variable interest rates of certain borrowings issued under its revolving credit facility.  The Company’s strategy to achieve that objective involves entering into interest rate swaps that are specifically designated to the Company’s revolving credit facility and accounted for as cash flow hedges. 

At December 31, 2013, the Company’s derivative instruments included three interest rate swap agreements as follows: 

Date Entered	Notional Amount		Fixed Interest Rate Paid*			Variable Interest Rate Received	Effective Date	Expiration Date
March 2009	$	175,000		2.85	%	1-month LIBOR	February 2011	February 2014
August 2011	$	150,000		0.80	%	1-month LIBOR	April 2012	January 2015
December 2011	$	175,000		1.60	%	1-month LIBOR	February 2014	February 2017

* plus applicable margin. 

Another of the Company’s objectives for utilizing derivative instruments is to reduce its exposure to fluctuations in cash flows due to changes in the price of diesel fuel.  The Company’s strategy to achieve that objective involves periodically entering into fuel hedges that are specifically designated to certain forecasted diesel fuel purchases and accounted for as cash flow hedges.

(a)   In accordance with the derivatives and hedging guidance, the effective portions of the changes in fair values of interest rate swaps and the fuel hedge have been recorded in equity as a component of AOCL.  As the critical terms of the interest rate swaps match the underlying debt being hedged, no ineffectiveness is recognized on these swaps and, therefore, all unrealized changes in fair value are recorded in AOCL.  Because changes in the actual price of diesel fuel and changes in the DOE index price do not offset exactly each reporting period, the Company assesses whether the fuel hedge is highly effective using the cumulative dollar offset approach.

(b)   Amounts reclassified from AOCL into earnings related to realized gains and losses on interest rate swaps are recognized when interest payments or receipts occur related to the swap contracts, which correspond to when interest payments are made on the Company’s hedged debt.

(c)   Amounts reclassified from AOCL into earnings related to realized gains and losses on the fuel hedge are recognized when settlement payments or receipts occur related to the hedge contract, which correspond to when the underlying fuel is consumed. 

The Company measures and records ineffectiveness on the fuel hedge in Cost of operations in the Consolidated Statements of Net Income on a monthly basis based on the difference between the DOE index price and the actual price of diesel fuel purchased, multiplied by the notional number of gallons on the contracts.  There was no significant ineffectiveness recognized on the fuel hedges during the years ended December 31, 2013, 2012 and 2011. 

See Note 13 for further discussion on the impact of the Company’s hedge accounting to its consolidated Comprehensive income and AOCL. 

Income Taxes  

Deferred tax assets and liabilities are determined based on differences between the financial reporting and income tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse.  The Company records valuation allowances to reduce net deferred tax assets to the amount considered more likely than not to be realized.

The Company is required to evaluate whether the tax positions taken on its federal and state income tax returns will more likely than not be sustained upon examination by the appropriate taxing authority.  If the Company determines that such tax positions will not be sustained, it records a liability for the related unrecognized tax benefits. The Company classifies its liability for unrecognized tax benefits as a current liability to the extent it anticipates making a payment within one year. 

Equity-Based Compensation 

The fair value of restricted stock units is determined based on the number of shares granted and the closing price of the Company’s common stock. 

All share-based compensation cost is measured at the grant date, based on the estimated fair value of the award, and is recognized on a straight-line basis as expense over the employee’s requisite service period.  The Company calculates potential income tax windfalls and shortfalls under the treasury stock method by including the impact of pro forma deferred tax assets in the calculation of diluted earnings per common share.  Under the stock-based compensation guidance, the Company elected to use the short-cut method to calculate the historical pool of windfall tax benefits.  The Company elected to use the tax law ordering approach for purposes of determining whether an excess of tax benefit has been realized. 

Warrants are valued using the Black-Scholes pricing model with a contractual life of five years, a risk free interest rate based on the 5-year U.S. treasury yield curve and expected volatility. The Company uses the historical volatility of its common stock over a period equivalent to the contractual life of the warrants to estimate the expected volatility.  Warrants issued to consultants are recorded as an element of the related cost of landfill development projects or to expense for warrants issued in connection with acquisitions. 

Equity-based compensation expense recognized during the years ended December 31, 2013, 2012 and 2011, was approximately $15,397 ($9,508 net of taxes), $17,289 ($11,803 net of taxes) and $11,879 ($7,365 net of taxes), respectively, and consisted of restricted stock unit and warrant expense.  The Company records equity-based compensation expense in Selling, general and administrative expenses in the Consolidated Statements of Net Income.  The total unrecognized compensation cost at December 31, 2013, related to unvested restricted stock unit awards was $25,138 and that future expense will be recognized over the remaining vesting period of the restricted stock unit awards, which extends to 2017.  The weighted average remaining vesting period of those awards is 1.1 years.

Per Share Information 

Basic net income per share attributable to Waste Connections’ common stockholders is computed using the weighted average number of common shares outstanding and vested and unissued restricted stock units deferred for issuance into the deferred compensation plan.  Diluted net income per share attributable to Waste Connections’ common stockholders is computed using the weighted average number of common and potential common shares outstanding.  Potential common shares are excluded from the computation if their effect is anti-dilutive. 

Advertising Costs 

Advertising costs are expensed as incurred.  Advertising expense for the years ended December 31, 2013, 2012 and 2011, was $3,704, $3,737 and $3,679, respectively, which is included in Selling, general and administrative expense in the Consolidated Statements of Net Income. 

Insurance Liabilities 

As a result of its high deductible or self-insured retention insurance policies, the Company is effectively self-insured for automobile liability, general liability, employer’s liability, environmental liability, cyber liability, employment practices liability, directors’ and officers’ liability as well as for employee group health insurance, property and workers’ compensation.  The Company’s insurance accruals are based on claims filed and estimates of claims incurred but not reported and are developed by the Company’s management with assistance from its third-party actuary and its third-party claims administrator.  The insurance accruals are influenced by the Company’s past claims experience factors, which have a limited history, and by published industry development factors.  At December 31, 2013 and 2012, the Company’s total accrual for self-insured liabilities was $42,732 and $43,935, respectively, which is included in Accrued liabilities in the Consolidated Balance Sheets. 

Reclassification

Certain amounts reported in the Company’s prior year’s financial statements have been reclassified to conform with the 2013 presentation.

2. USE OF ESTIMATES AND ASSUMPTIONS 

In preparing the Company’s consolidated financial statements, several estimates and assumptions are made that affect the accounting for and recognition of assets, liabilities, revenues and expenses.  These estimates and assumptions must be made because certain of the information that is used in the preparation of the Company’s consolidated financial statements is dependent on future events, cannot be calculated with a high degree of precision from data available or is simply not capable of being readily calculated based on generally accepted methodologies.  In some cases, these estimates are particularly difficult to determine and the Company must exercise significant judgment.  The most difficult, subjective and complex estimates and the assumptions that deal with the greatest amount of uncertainty are related to the Company’s accounting for landfills, self-insurance accruals, income taxes, allocation of acquisition purchase price and asset impairments, which are discussed in Note 1.  An additional area that involves estimation is when the Company estimates the amount of potential exposure it may have with respect to litigation, claims and assessments in accordance with the accounting guidance on contingencies.  Actual results for all estimates could differ materially from the estimates and assumptions that the Company uses in the preparation of its consolidated financial statements. 

3. ACQUISITIONS

The Company recognizes, separately from goodwill, the identifiable assets acquired and liabilities assumed at their estimated acquisition date fair values.  The Company measures and recognizes goodwill as of the acquisition date as the excess of:  (a) the aggregate of the fair value of consideration transferred, the fair value of any noncontrolling interest in the acquiree (if any) and the acquisition date fair value of the Company's previously held equity interest in the acquiree (if any), over (b) the fair value of assets acquired and liabilities assumed.  If information about facts and circumstances existing as of the acquisition date is incomplete by the end of the reporting period in which a business combination occurs, the Company will report provisional amounts for the items for which the accounting is incomplete.  The measurement period ends once the Company receives the information it was seeking; however, this period will not exceed one year from the acquisition date.  Any material adjustments recognized during the measurement period will be reflected retrospectively in the consolidated financial statements of the subsequent period.  The Company recognizes acquisition-related costs as expense.

R360 Acquisition

On October 25, 2012, the Company completed the acquisition of all of the outstanding equity interests in certain entities that, together with the operating subsidiaries of such entities, hold the business of R360 Environmental Solutions, Inc. (“R360”) for total cash consideration of $1,338,344, net of cash acquired, the assumption of outstanding debt totaling $9,306 and the assumption of contingent consideration totaling $37,293. The acquisition was funded with available cash and with borrowings of $475,000 under the Company’s senior revolving credit facility and of $800,000 under an uncollateralized term loan facility. The R360 business consists of E&P landfills, E&P liquid waste injection wells, E&P waste treatment and recovery facilities and oil recovery facilities at 24 operating locations across Louisiana, New Mexico, North Dakota, Oklahoma, Texas and Wyoming. The R360 acquisition enabled the Company to significantly expand its scope of E&P waste services and contributed towards the achievement of the Company’s strategy to expand through acquisitions.

The results of operations of the R360 business have been included in the Company’s consolidated financial statements from its acquisition date.  Total revenues during the period from October 25, 2012 to December 31, 2012, generated from the R360 operations and included within consolidated revenues were $40,190. Total pre-tax earnings during the period from October 25, 2012 to December 31, 2012, generated from the R360 operations and included within consolidated income before income taxes, were $8,669.

The Prairie Disposal contingent consideration represents the fair value of up to $25,000 of contingent consideration payable to the former owners of Prairie Disposal, LLC and Prairie Liquids, LLC (“Prairie”) based on the future achievement of certain milestones over an expected two-year period. The fair value of the contingent consideration was determined using probability assessments of the expected future cash flows over the two-year period in which the obligation is expected to be settled, and applied a discount rate of 2.0%. As of December 31, 2013, the fair value of the obligation increased to $24,944 due to the accretion of interest on the liability. Any changes in the fair value of the contingent consideration subsequent to the acquisition date will be charged or credited to expense until the contingency is settled.

The Oilfield Holdings contingent consideration represents the fair value of up to $8,000 payable to the former owners of Oilfield Holdings if R360 completed a qualifying cash event, as defined in the Oilfield Holdings purchase agreement. A qualifying cash event included the sale of R360. Payment of the contingent consideration required the qualifying cash event to generate a return on investment above a certain minimum threshold. The Company’s R360 acquisition generated a return on investment that resulted in the payment of the $8,000 liability to the former owners of Oilfield Holdings in November 2012.

The Calpet contingent consideration represents the fair value of up to $4,221 payable to the former owners of Calpet, LLC based on the future achievement of revenue targets through June 2013. The fair value of the contingent consideration was determined using probability assessments of the expected future cash flows over the one-year period in which the obligations is expected to be settled, and applied a discount rate of 2.0%. During the year ended December 31, 2013, $2,500 of the contingent consideration was earned and paid to the former owners and $1,250 of the contingent consideration was not earned and credited to expense. Any changes in the fair value of the $471 remaining contingent consideration obligation at December 31, 2013 will be charged or credited to expense until the contingency is settled.

The Claco Services contingent consideration represents the fair value of up to $750 payable to the former owners of Claco Services through December 2013. The Company paid $375 of this assumed liability in both December 2012 and December 2013.

The R360 acquisition resulted in goodwill acquired totaling $395,339, which is expected to be deductible for tax purposes.  The goodwill is attributable to growth opportunities, at existing R360 operations as well additional acquisitions of companies providing non-hazardous oilfield waste treatment and disposal services, and synergies that are expected to arise as a result of the acquisition.

Cash consideration for the R360 acquisition included payment for the estimated net working capital of $18,906, as defined in the acquisition agreement, which was subject to final adjustment subsequent to the close of the acquisition. In March 2013, Waste Connections received $18,000 from the former owners of R360 due to the final adjustment to the net working capital that was estimated at the closing date.

The gross amount of trade receivables due under contracts was $52,777, of which $2,616 was expected to be uncollectible.  The Company did not acquire any other class of receivable as a result of the R360 acquisition. 

The Company incurred $2,655, of acquisition-related costs for the R360 acquisition.  These expenses are included in Selling, general and administrative expenses in the Company’s Consolidated Statements of Net Income. 

Other Acquisitions

The Company acquired eight individually immaterial non-hazardous solid waste collection businesses during the year ended December 31, 2013. The total acquisition-related costs incurred for these acquisitions was $1,946. These expenses are included in Selling, general and administrative expenses in the Company’s Consolidated Statements of Net Income. 

In July 2012, the Company completed the acquisition of 100% of the interests in the operations of SKB Environmental, Inc. (“SKB”), a provider of solid waste transfer and disposal services in Minnesota, in exchange for total consideration of $86,763.  Pursuant to the stock purchase agreement, the Company was required to remit additional consideration to the former shareholders of SKB if the acquired operations exceeded earnings targets specified in the stock purchase agreement over a one-year earn out period ending June 30, 2013.  The Company computed the fair value of the contingent consideration at the purchase date to be $20,711, based upon probability assessments of the expected future cash flows over the one-year period in which the obligation was expected to be settled, to which the Company had applied a discount rate of 2.0%. Based upon the actual earnings of SKB over the one-year earn out period, the final additional consideration was $25,768, which the Company paid in July 2013. The difference between the final contingent consideration paid and the fair value of the contingent consideration at the purchase date was charged to expense in the Company’s Consolidated Statements of Net Income.

On March 1, 2012, the Company completed the acquisition of 100% of the interests in the operations of Alaska Pacific Environmental Services Anchorage, LLC and Alaska Green Waste Solutions, LLC (together, “Alaska Waste”). Alaska Waste provides solid waste collection, transfer and composting services in Anchorage, the Mat-Su Valley, Fairbanks, the Kenai Peninsula and Kodiak Island. The Company paid $133,402 for the purchased operations. Pursuant to the asset purchase agreement, the Company is required to remit up to $4,000 of additional consideration to the former owners of Alaska Waste if new business is generated through the privatization of certain markets currently serviced by municipalities. The Company computed the fair value of the contingent consideration at the purchase date to be $602, based upon probability assessments of the expected future cash flows over the two-year period in which the obligation is expected to be settled, to which the Company applied a discount rate of 2.8%. As of December 31, 2013, the obligation recognized at the purchase date has not materially changed. Any changes in the fair value of the contingent consideration subsequent to the acquisition date will be charged or credited to expense until the contingency is settled.

In addition to the acquisitions of SKB and Alaska Waste, the Company acquired 10 individually immaterial non-hazardous solid waste collection, transfer, disposal and E&P businesses during the year ended December 31, 2012. The total acquisition-related costs incurred for these acquisitions was $2,658. These expenses are included in Selling, general and administrative expenses in the Company’s Consolidated Statements of Net Income. 

In August 2011, the Company’s subsidiary, Capital Region Landfills, Inc. (“CRL”), entered into an agreement with the Town of Colonie, a municipal corporation of the state of New York, to operate a municipal solid waste disposal facility (the “Colonie Landfill”) for an initial term of 25 years. The agreement became effective on September 19, 2011.  As consideration for operating equipment and the right to operate the Colonie Landfill, CRL remitted an initial payment of $23,860. CRL is also required to remit up to $55,470 of additional consideration over the term of the agreement, comprised of $11,500 payable over a five-year period ending September 2016 and up to $43,970 payable over the term of the agreement if certain expansion criteria are met and certain annual tonnage targets are exceeded as specified in the operating agreement. The Company computed the fair value of the additional consideration using probability assessments of the expected future cash flows over estimated payment terms of four to 25 years, to which the Company applied discount rates ranging from 2.5% to 5.0%, resulting in a total obligation recognized at the effective date of $32,928, which consisted of $10,656 recorded as Notes issued to sellers and $22,272 recorded as contingent consideration in Long-term contingent consideration.  CRL is also responsible for all final capping, closure and post-closure liabilities and estimates the total obligation in current dollars to be $21,287, the net present value of which is $1,429. This obligation was recorded in Other long-term liabilities. The obligation for contingent consideration recognized at the purchase date increased $1,144, $1,086 and $301 during the years ended December 31, 2013, 2012 and 2011, respectively, due to the accretion of interest on the liability. Any changes in the fair value of the contingent consideration subsequent to the acquisition date will be charged or credited to income until the contingency is settled.

On April 1, 2011, the Company completed the acquisition of a 100% interest in Hudson Valley Waste Holding, Inc., and its wholly-owned subsidiary, County Waste and Recycling Service, Inc. (collectively, “County Waste”). As part of this acquisition, the Company acquired a 50% interest in Russell Sweepers, LLC, a provider of sweeper services, resulting in a 50% noncontrolling interest that was recognized at fair value on the purchase date.  The operations include six collection operations, three transfer stations and one recycling facility across six markets in New York and Massachusetts. The Company paid $299,000 for the purchased operations plus amounts paid for the purchase of accounts receivable and other prepaid assets and estimated working capital, which amounts were subject to post-closing adjustments.  No other consideration, including contingent consideration, was transferred by the Company to acquire these operations. Total revenues during the year ended December 31, 2011, generated from the County Waste operations and included within consolidated revenues were $93,713. Total pre-tax earnings during the year ended December 31, 2011, generated from the County Waste operations and included within consolidated income before income taxes were $7,276.  

In addition to the County Waste acquisition and Colonie Landfill transaction, the Company acquired 11 individually immaterial non-hazardous solid waste collection and transfer businesses during the year ended December 31, 2011. The total acquisition-related costs incurred for these acquisitions was $1,744. These expenses are included in Selling, general and administrative expenses in the Company’s Consolidated Statements of Net Income. 

The results of operations of the acquired businesses have been included in the Company’s consolidated financial statements from their respective acquisition dates.  The Company expects these acquired businesses to contribute towards the achievement of the Company’s strategy to expand through acquisitions. Goodwill acquired is attributable to the synergies and ancillary growth opportunities expected to arise after the Company’s acquisition of these businesses.

Revolver under Credit Facility

The Company has a senior revolving credit facility with a syndicate of banks for which Bank of America, N.A. acts as administrative agent.  The maximum borrowings available under the Company’s credit facility were $1,200,000 as of December 31, 2013 and 2012.  The Company has the ability to increase commitments under the revolving credit facility from $1,200,000 to $1,500,000, subject to conditions including that no default, as defined in the credit agreement, has occurred, although no existing lender has any obligation to increase its commitment. Swing line loans may be issued at the request of the Company in an aggregate amount not to exceed a $25,000 sublimit and there is no maximum amount of standby letters of credit that can be issued under the credit facility; however, the issuance of swing line loans and standby letters of credit both reduce the amount of total borrowings available.  As of December 31, 2013, $727,100 was outstanding under the credit facility, exclusive of outstanding standby letters of credit of $75,166. As of December 31, 2012, $787,000 was outstanding under the credit facility, exclusive of outstanding standby letters of credit of $87,252. The credit facility matures in May 2018.  The Company has $4,722 of debt issuance costs recorded in Other assets, net in the Consolidated Balance Sheets at December 31, 2013 which are being amortized through the maturity date, or May 2018.

(DOLLAR AMOUNTS IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)

The borrowings under the credit facility bear interest, at the Company’s option, at either the base rate plus the applicable base rate margin (approximately 3.75% and 3.53% at December 31, 2013 and 2012, respectively) on base rate loans and swing line loans, or the LIBOR rate plus the applicable LIBOR margin (approximately 1.67% and 1.48% at December 31, 2013 and 2012, respectively) on LIBOR loans.  The applicable margins under the credit facility vary depending on the Company’s leverage ratio, as defined in the credit agreement.  As of December 31, 2013 and 2012, the margins were 1.50% and 1.28%, respectively, for LIBOR loans and 0.50% and 0.28%, respectively, for base rate loans and swing line loans.  As of December 31, 2013 and 2012, all outstanding borrowings under the credit facility were in LIBOR loans and swing line loans.

The credit facility requires the Company to pay an annual commitment fee on the unused portion of the facility.  The commitment fee was 0.23% as of each of December 31, 2013 and 2012. 

The borrowings under the credit facility are not collateralized.  The credit agreement contains representations, warranties, covenants and events of default, including a change of control event of default and limitations on incurrence of indebtedness and liens, new lines of business, mergers, transactions with affiliates and restrictive payments. During the continuance of an event of default, the lenders may take a number of actions, including declaring the entire amount then outstanding under the credit agreement due and payable. The credit facility contains cross-defaults if the Company defaults on the term loan facility, the Master Note Purchase Agreement or certain other debt. The credit facility requires that the Company maintain specified quarterly leverage and interest coverage ratios. The required leverage ratio cannot exceed 3.50x total debt to earnings before interest, taxes, depreciation and amortization, or EBITDA. The required interest coverage ratio must be at least 2.75x total interest expense to earnings before interest and taxes, or EBIT. As of December 31, 2013 and 2012, the Company’s leverage ratio was 3.08x and 3.28x, respectively. As of December 31, 2013 and 2012, the Company’s interest coverage ratio was 6.33x and 6.88x, respectively.

Term Loan Facility

On October 25, 2012, the Company entered into a term loan facility in the original principal amount of $800,000 with Bank of America, N.A. and the other banks and lending institutions party thereto, as lenders, Bank of America, N.A., as administrative agent, and JPMorgan Chase Bank, N.A. and Wells Fargo Bank, National Association, as co-syndication agents. The term loan is subject to principal payments which commenced at $10,000 per quarter in April 2013, increase to $20,000 per quarter in April 2014 and increase again to $30,000 per quarter in April 2015. A final principal payment of $390,000 is due upon maturity of the term loan facility on October 25, 2017. The Borrowings under the term loan facility were required to be used only to fund the R360 acquisition pursuant to the R360 purchase and sale agreement and to pay fees and expenses incurred in connection with the R360 acquisition and the Company’s entry into the term loan facility. The Company is amortizing the $7,245 debt issuance costs through the maturity date, or October 2017.

Outstanding amounts on the term loan facility can be either base rate loans or LIBOR loans. At December 31, 2013 and 2012, all amounts outstanding under the term loan facility were in LIBOR loans which bear interest at the LIBOR rate plus the applicable LIBOR margin (approximately 2.04% and 2.21% at December 31, 2013 and 2012, respectively).  The LIBOR rate is determined by the administrative agent in a customary manner as described in the term loan agreement. The applicable margins under the term loan agreement vary depending on the Company’s leverage ratio, as defined in the term loan agreement, as amended, and range from 1.375% per annum to 2.375% per annum for LIBOR loans. As of December 31, 2013 and 2012, the margin was 1.875% and 2.0%, respectively, for LIBOR loans.  Borrowings under the term loan facility are not collateralized.

The term loan facility contains representations and warranties and places certain business, financial and operating restrictions on the Company relating to, among other things, indebtedness, liens, investments, mergers, consolidation and disposition of assets, sale and leaseback transactions, restricted payments and redemptions, burdensome agreements, business activities, transactions with affiliates, prepayments of indebtedness and accounting changes. During the continuance of an event of default, the lenders may take a number of actions, including declaring the entire amount then outstanding under the term loan facility due and payable. The term loan facility contains cross-defaults if the Company defaults on the senior revolving credit facility, the Master Note Purchase Agreement or certain other debt. The term loan facility requires that the Company maintain specified quarterly leverage and interest coverage ratios. The required leverage ratio cannot exceed 3.50x total debt to EBITDA. The required interest coverage ratio must be at least 2.75x total interest expense to EBIT. As of December 31, 2013 and 2012, the Company’s leverage ratio was 3.08x and 3.28x, respectively. As of December 31, 2013 and 2012, the Company’s interest coverage ratio was 6.33x and 6.88x, respectively.

Senior Notes due 2016, 2018 and 2021 

On April 1, 2011, the Company entered into a Second Supplement to the Master Note Purchase Agreement with certain accredited institutional investors, pursuant to which the Company issued and sold to the investors on that date $250,000 of senior uncollateralized notes at fixed interest rates with interest payable in arrears semi-annually on October 1 and April 1 beginning on October 1, 2011 in a private placement. Of these notes, $100,000 will mature on April 1, 2016 with an annual interest rate of 3.30% (the “2016 Notes”), $50,000 will mature on April 1, 2018 with an annual interest rate of 4.00% (the “2018 Notes”), and $100,000 will mature on April 1, 2021 with an annual interest rate of 4.64% (the “2021 Notes”).

The 2015 Notes, 2016 Notes, 2018 Notes, 2019 Notes, and 2021 Notes (collectively, the “Senior Notes”) are uncollateralized obligations and rank equally in right of payment with each of the Senior Notes, the obligations under the Company’s senior uncollateralized revolving credit facility and the obligations under the Company’s term loan facility. The Senior Notes are subject to representations, warranties, covenants and events of default.  The Master Note Purchase Agreement contains cross-defaults if the Company defaults on the credit facility, the term loan facility or certain other debt. The Master Note Purchase Agreement requires that the Company maintain specified quarterly leverage and interest coverage ratios. The required leverage ratio cannot exceed 3.75x total debt to EBITDA. The required interest coverage ratio must be at least 2.75x total interest expense to EBIT. As of December 31, 2013 and 2012, the Company’s leverage ratio was 3.08x and 3.28x, respectively. As of December 31, 2013 and 2012, the Company’s interest coverage ratio was 6.33x and 6.88x, respectively.

Upon the occurrence of an event of default, payment of the Senior Notes may be accelerated by the holders of the respective notes.  The Senior Notes may also be prepaid at any time in whole or from time to time in any part (not less than 5% of the then-outstanding principal amount) by the Company at par plus a make-whole amount determined in respect of the remaining scheduled interest payments on the Senior Notes, using a discount rate of the then current market standard for United States treasury bills plus 0.50%.  In addition, the Company will be required to offer to prepay the Senior Notes upon certain changes in control. 

The Company may issue additional series of senior uncollateralized notes, including floating rate notes, pursuant to the terms and conditions of the Master Note Purchase Agreement, as amended, provided that the purchasers of the Senior Notes shall not have any obligation to purchase any additional notes issued pursuant to the Master Note Purchase Agreement and the aggregate principal amount of the outstanding notes and any additional notes issued pursuant to the Master Note Purchase Agreement shall not exceed $1,250,000.

In October 2013, the Company gave notice to redeem its Tehama Bond with a remaining principal balance of $205. The Company paid in full the principal and accrued interest on this bond on January 8, 2014.

The variable-rate bonds are all remarketed weekly by a remarketing agent to effectively maintain a variable yield.  If the remarketing agent is unable to remarket the bonds, then the remarketing agent can put the bonds to the Company.  The Company has obtained standby letters of credit, issued under its senior revolving credit facility, to guarantee repayment of the bonds in this event.  The Company classified these borrowings as long-term at December 31, 2013, because the borrowings are supported by standby letters of credit issued under the Company’s senior revolving credit facility which matures in May 2018.

8. FAIR VALUE OF FINANCIAL INSTRUMENTS

The Company uses a three-tier fair value hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis, as well as assets and liabilities measured at fair value on a non-recurring basis, in periods subsequent to their initial measurement.  These tiers include:  Level 1, defined as quoted market prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, model-based valuation techniques for which all significant assumptions are observable in the market, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and Level 3, defined as unobservable inputs that are not corroborated by market data.

WASTE CONNECTIONS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(DOLLAR AMOUNTS IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)

The Company’s financial assets and liabilities recorded at fair value on a recurring basis include derivative instruments and restricted assets.  The Company’s derivative instruments are pay-fixed, receive-variable interest rate swaps and a pay-fixed, receive-variable diesel fuel hedge.  The Company’s interest rate swaps are recorded at their estimated fair values based on quotes received from financial institutions that trade these contracts.  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.  The Company uses a discounted cash flow (“DCF”) model to determine the estimated fair value of the diesel fuel hedge.  The assumptions used in preparing the DCF model include: (i) estimates for the forward DOE index curve; and (ii) the discount rate based on risk-free interest rates over the term of the hedge contract.  The DOE index curve used in the DCF model was obtained from financial institutions that trade these contracts and ranged from $3.79 to $4.00 at December 31, 2013 and from $3.68 to $3.87 at December 31, 2012.  The weighted average DOE index curve used in the DCF model was $3.91 and $3.77 at December 31, 2013 and 2012, respectively. Significant increases (decreases) in the forward DOE index curve would result in a significantly higher (lower) fair value measurement. For the Company’s interest rate swaps and fuel hedge, the Company also considers the Company’s creditworthiness in its determination of the fair value measurement of these instruments in a net liability position and the banks’ creditworthiness in its determination of the fair value measurement of these instruments in a net asset position.  The Company’s restricted assets 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 assets measured at fair value are invested primarily in U.S. government and agency securities. 

The Company’s assets and liabilities measured at fair value on a recurring basis at December 31, 2013 and 2012, were as follows: 

	Fair Value Measurement at December 31, 2013 Using
	Total			Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)			Significant Unobservable Inputs (Level 3)

9. OFFICE RELOCATIONS

In December 2011, the Company commenced a relocation of its corporate headquarters from Folsom, California to The Woodlands, Texas, which was substantially completed in 2012. Costs related to personnel and office relocation expenses are recorded in Selling, general and administrative expenses in the Consolidated Statements of Net Income.  During the year ended December 31, 2013, the Company incurred losses on the cessation of use of prior office leases of $9,160 for its former corporate headquarters in Folsom, California, and $742 for its E&P segment’s former regional offices in Houston, Texas. In October 2013, the Company remitted a payment to terminate the remaining lease obligation of its former headquarters in Folsom, California.  These costs are recorded in Loss on prior office leases in the Consolidated Statements of Net Income.

10. GAIN FROM LITIGATION SETTLEMENT

In November 2010, the Company’s subsidiary, Potrero Hills Landfill, Inc. (“PHLF”), which owns and operates the Potrero Hills Landfill in Solano County, California, initiated contractual arbitration proceedings with Judicial Arbitration and Mediation Services, Inc. in San Francisco against The Ratto Group of Companies, Inc. (“Ratto”) alleging Ratto’s breach of the parties’ Solid Waste Disposal Agreement.

The case was arbitrated in February and March 2012 before the Honorable Fern Smith (ret.). On August 13, 2012, Judge Smith issued her Final Award finding that Ratto had breached the Solid Waste Disposal Agreement by failing to include PHLF in its 2010 bid to Sonoma County and awarding PHLF lost profits, attorney’s fees and costs. Pursuant to this Final Award, on September 13, 2012, Ratto remitted to PHLF $3,551, which was recorded as Gain from litigation settlement in the Consolidated Statements of Net Income.

Financial Surety Bonds 

The Company uses financial surety bonds for a variety of corporate guarantees.  The two largest uses of financial surety bonds are for municipal contract performance guarantees and asset closure and retirement requirements under certain environmental regulations. Environmental regulations require demonstrated financial assurance to meet final capping, closure and post-closure requirements for landfills.  In addition to surety bonds, these requirements may also be met through alternative financial assurance instruments, including insurance, letters of credit and restricted asset deposits. 

At December 31, 2013 and 2012, the Company had provided customers and various regulatory authorities with surety bonds in the aggregate amount of approximately $304,416 and $277,841, respectively, to secure its asset closure and retirement requirements and $89,196 and $83,738, respectively, to secure performance under collection contracts and landfill operating agreements. 

The Company owns a 9.9% interest in a company that, among other activities, issues financial surety bonds to secure landfill final capping, closure and post-closure obligations for companies operating in the solid waste industry.  The Company accounts for this investment under the cost method of accounting.  There have been no identified events or changes in circumstances that may have a significant adverse effect on the fair value of the investment.  This investee company and the parent company of the investee have written financial surety bonds for the Company, of which $163,187 and $153,337 were outstanding as of December 31, 2013 and 2012, respectively.  The Company’s reimbursement obligations under these bonds are secured by a pledge of its stock in the investee company. 

Unconditional Purchase Obligations

At December 31, 2013, the Company’s unconditional purchase obligations consist of multiple fixed-price fuel purchase contracts under which it has 4.6 million gallons remaining to be purchased for a total of $16,089, plus taxes and transportation upon delivery.  These fuel purchase contracts expire on or before December 31, 2014.

CONTINGENCIES 

Environmental Risks

The Company expenses costs incurred to investigate and remediate environmental issues unless they extend the economic useful life of related assets. The Company records liabilities when it is probable that an obligation has been incurred and the amounts can be reasonably estimated. The remediation reserves cover anticipated costs, including remediation of environmental damage that waste facilities may have caused to neighboring landowners or residents as a result of contamination of soil, groundwater or surface water, including damage resulting from conditions existing prior to the Company’s acquisition of such facilities. The Company’s estimates are based primarily on investigations and remediation plans established by independent consultants, regulatory agencies and potentially responsible third parties. The Company does not discount remediation obligations. At December 31, 2013 and 2012, the current portion of remediation reserves was $3,226 and $4,097, respectively, which is included in Accrued liabilities in the Consolidated Balance Sheets. At December 31, 2013 and 2012, the long-term portion of remediation reserves was $725 and $1,214, respectively, which is included in Other long-term liabilities in the Consolidated Balance Sheets. The Company’s liabilities for remediation reserves were assumed in the R360 acquisition. The Company did not have liabilities for remediation reserves recorded at December 31, 2011. Any substantial increase in the liabilities for remediation of environmental damage incurred by the Company could have a material adverse effect on the Company’s financial condition, results of operations or cash flows. 

Legal Proceedings

In the normal course of its business and as a result of the extensive governmental regulation of the solid waste and E&P waste industries, the Company is subject to various judicial and administrative proceedings involving federal, state or local agencies. In these proceedings, an agency may seek to impose fines on the Company or to revoke or deny renewal of an operating permit held by the Company. From time to time, the Company may also be subject to actions brought by special interest or other groups, adjacent landowners or residents in connection with the permitting and licensing of landfills, transfer stations, and E&P waste treatment, recovery and disposal operations, or alleging environmental damage or violations of the permits and licenses pursuant to which the Company operates.

In addition, the Company is a party to various claims and suits pending for alleged damages to persons and property, alleged violations of certain laws and alleged liabilities arising out of matters occurring during the normal operation of the waste management business. Except as noted in the matters described below, as of December 31, 2013, there is no current proceeding or litigation involving the Company or its property that the Company believes could have a material adverse impact on its business, financial condition, results of operations or cash flows.

Chaparral, New Mexico Landfill Permit Litigation

The Company’s subsidiary, High Desert Solid Waste Facility, Inc. (formerly known as Rhino Solid Waste, Inc.) (“HDSWF”), owns undeveloped property in Chaparral, New Mexico, for which it sought a permit to operate a municipal solid waste landfill.  The New Mexico Environment Department (the “Department”) approved the permit for the facility on January 30, 2002.  Colonias Development Council (“CDC”), a nonprofit organization, appealed the Department’s decision to the courts of New Mexico, alleging primarily that the Department failed to consider the social impact of the landfill on the community of Chaparral, and failed to consider regional planning issues.  On July 18, 2005, in Colonias Dev. Council v. Rhino Envtl. Servs., Inc. (In re Rhino Envtl. Servs.), 2005 NMSC 24, 117 P.3d 939, the New Mexico Supreme Court remanded the matter back to the Department to conduct a limited public hearing on certain evidence that CDC claimed was wrongfully excluded from consideration by the hearing officer, and to allow the Department to reconsider the evidence already proffered concerning the impact of the landfill on the surrounding community’s quality of life.  In July 2007, the Department, CDC, the Company and Otero County signed a stipulation requesting a postponement of the limited public hearing to allow the Company time to explore a possible relocation of the landfill to a new site. Since 2007, the Department has issued several orders postponing the limited public hearing, and on October 17, 2012, it granted a request by the parties to hold the limited public hearing in abeyance until further notice.

In July 2009, HDSWF purchased approximately 325 acres of undeveloped land comprising a proposed new site from the State of New Mexico.  HDSWF filed a formal landfill permit application for the new site with the Department on September 17, 2010.  On September 12, 2011, the Department deemed the permit application complete and a public hearing on the matter had been tentatively scheduled for April 9, 2012, in Chaparral, New Mexico. On November 9, 2011, HDSWF filed a motion with the Department to hold in abeyance indefinitely the notice for public hearing and the permit hearing, and HDSWF agreed to provide the Department with at least 120 days’ prior notice of any desired, future permit hearing. The Department granted the motion. HDSWF requested the abeyance to defer capital expenditures related to permitting the new site until mid to late 2014, when HDSWF expects to have a better understanding of several current market conditions and regulatory factors that affect the timing and feasibility of the project. These conditions and factors include: the status of the Company’s Solid Waste Disposal and Operating Agreement for the collection and disposal of solid waste generated within the City of El Paso, effective April 28, 2004, which has a 10-year term; the status of El Paso Disposal, LP’s Solid Waste Franchise Agreement for the collection of solid waste generated within the City of El Paso, effective September 1, 2011, which has a 40-month term; and whether certain closed or non-operating disposal facilities in the El Paso market area are reopened and whether those facilities are operated by private or public entities. On February 4, 2014, the Mayor of the City of El Paso approved and the City Council passed an ordinance amending the El Paso City Code to, among other things, rescind the City’s flow control requirement directing waste collected within its boundaries to City-owned disposal facilities, which was scheduled to become effective on September 1, 2014.

At December 31, 2013, the Company had $11,778 of capitalized expenditures related to this landfill development project.  Depending on the outcome of the market conditions and regulatory factors described above, the Company may decide in mid to late 2014 to abandon the project and expense the $11,778 of capitalized expenditures, less the recoverable value of the undeveloped properties and other amounts recovered, which would likely have a material adverse effect on the Company’s results of operations for that period.  Alternatively, if the outcome of the market conditions and regulatory factors described above is such that the Company believes the market for disposal of solid waste generated in the City of El Paso will remain competitive, HDSWF may decide in mid to late 2014 to resume its permitting process for the new site. Under those circumstances, if the Department ultimately denies the landfill permit application for the new site, HDSWF intends to actively resume its efforts to enforce the previously issued landfill permit for the original site in Chaparral. If the Company is ultimately issued a permit to operate the landfill at the new site purchased in July 2009, the Company will be required to expense in a future period $10,324 of capitalized expenditures related to the original Chaparral property, less the recoverable value of that undeveloped property and other amounts recovered, which would likely have a material adverse effect on the Company’s results of operations for that period. If the Company instead is ultimately issued a permit to operate the landfill at the original Chaparral property, the Company will be required to expense in a future period $1,454 of capitalized expenditures related to the new site purchased in July 2009, less the recoverable value of that undeveloped property and other amounts recovered. If the Company is not ultimately issued a permit to operate the landfill at either one of the two sites, the Company will be required to expense in a future period the $11,778 of capitalized expenditures, less the recoverable value of the undeveloped properties and other amounts recovered, which would likely have a material adverse effect on the Company’s results of operations for that period.

Harper County, Kansas Landfill Permit Litigation

The Company opened a municipal solid waste landfill in Harper County, Kansas in January 2006, following the issuance by the Kansas Department of Health and Environment (“KDHE”) of a permit to operate the landfill.  The landfill has operated continuously since that time.  In 2005, landfill opponents (the “Plaintiffs”) filed a suit (Board of Comm’rs of Sumner County, Kansas, Tri-County Concerned Citizens and Dalton Holland v. Roderick Bremby, Sec’y of the Kansas Dep’t of Health and Env’t, et al.) in the District Court of Shawnee County, Kansas, seeking a judicial review of KDHE’s decision to issue the permit, alleging that a site analysis prepared for the Company and submitted to KDHE as part of the process leading to the issuance of the permit was deficient in several respects.  The action sought to stay the effectiveness of the permit and to nullify it.  The Company intervened in this lawsuit shortly after it was filed. In June 2012, the District Court denied the Plaintiffs’ demand for revocation of the permit, and affirmed KDHE’s decision that the issuance of the permit met all applicable regulatory requirements. The Plaintiffs filed an appeal with the Kansas Court of Appeals. On September 13, 2013, the Kansas Court of Appeals affirmed KDHE’s issuance of the landfill permit to the Company. On October 15, 2013, the Plaintiffs petitioned the Kansas Supreme Court to review the decision of the Court of Appeals, which review is discretionary. To date, the Kansas Supreme Court has not decided if it will review this matter. The Company believes that it will ultimately prevail in this matter, and the Company will continue to have the right to operate the landfill during the pendency of any further appeal. Only in the event that a final, materially adverse determination with respect to the permit is received would there likely be a material adverse effect on the Company’s reported results of operations in the future.  If as a result of this litigation, after exhausting all appeals, the Company was unable to continue to operate the landfill, the Company estimates that it would be required to record a pre-tax impairment charge of approximately $20,000 to reduce the carrying value of the landfill to its estimated fair value. In addition, the Company estimates the current annual impact to its pre-tax earnings that would result if it was unable to continue to operate the landfill would be approximately $3,400 per year. 

Solano County, California Measure E/Landfill Expansion Litigation

The Company and one of its subsidiaries, Potrero Hills Landfill, Inc. (“PHLF”), were named as real parties in interest in an amended complaint captioned Sustainability, Parks, Recycling and Wildlife Legal Defense Fund v. County of Solano, which was filed in the Superior Court of California, County of Solano, on July 9, 2009 (the original complaint was filed on June 12, 2009).  This lawsuit sought to compel Solano County to comply with Measure E, a ballot initiative and County ordinance passed in 1984 that the County has not enforced against PHLF since at least 1992.  Measure E directed in part that Solano County shall not allow the importation into the County of any solid waste which originated or was collected outside the County in excess of 95,000 tons per year.  The Sustainability, Parks, Recycling and Wildlife Legal Defense Fund (“SPRAWLDEF”) lawsuit also sought to overturn Solano County’s approval of the use permit for the expansion of the Potrero Hills Landfill and the related Environmental Impact Report (“EIR”), arguing that both violated Measure E and that the EIR violated the California Environmental Quality Act (“CEQA”).  Two similar actions seeking to enforce Measure E, captioned Northern California Recycling Association v. County of Solano and Sierra Club v. County of Solano, were filed in the same court on June 10, 2009, and August 10, 2009, respectively.  The Northern California Recycling Association (“NCRA”) case did not name the Company or any of its subsidiaries as parties and did not contain any CEQA claims, but sought to enforce Measure E and overturn the use permit for the expansion.  The Sierra Club case named PHLF as a real party in interest, and sought to overturn the use permit for the expansion of the landfill on Measure E grounds (but did not raise CEQA claims).

On May 12, 2010, the Solano County Superior Court issued a written opinion addressing all three cases. The Court upheld Measure E in part by judicially rewriting the law, and then issued a writ of mandamus directing Solano County to enforce Measure E as rewritten. The Court decided that it could cure the law’s discrimination against out-of-county waste by revising Measure E to only limit the importation of waste into Solano County from other counties in California, but not from other states. In the same opinion, the Superior Court rejected the requests from petitioners in the cases for a writ of administrative mandamus to overturn the use permit approved by Solano County in June 2009 for the expansion of PHLF’s landfill, thereby leaving the expansion use permit in place.

In December 2010, the Superior Court entered final judgments and writs of mandamus in the three cases, and Solano County, the Company, PHLF and numerous waste hauling company intervenors filed notices of appeal, which stayed the judgments and writs pending the outcome of the appeal.  Petitioners Sierra Club and SPRAWLDEF cross-appealed the Court’s ruling denying their petitions for writs to overturn PHLF’s use permit for the expansion.

As part of the final judgments, the Solano County Superior Court retained jurisdiction over any motions for attorneys’ fees under California's Private Attorney General statute. Petitioners NCRA, SPRAWLDEF and Sierra Club each filed a bill of costs and a motion for attorney fees totaling $771. On May 31, 2011, the court issued a final order awarding petitioners $452 in attorneys’ fees, $411 of which relates to the SPRAWLDEF and Sierra Club cases in which the Company or PHLF is a named party. The court allocated 50% of the fee amount to PHLF, none of which the Company recorded as a liability at December 31, 2013. The Company and Solano County appealed this attorneys’ fees order in July 2011, which stayed the fee order. As explained below, in January 2014 the Court of Appeal reversed the attorney fee award.

On September 25, 2012, Governor Jerry Brown signed into law Assembly Bill 845 (“AB 845”), an act of the California Legislature, effective January 1, 2013. AB 845 expressly prohibits counties from restricting or limiting the importation of solid waste into a privately owned facility in a county based on the waste’s place of origin. In light of AB 845, the Company filed a motion to dismiss the cross appeals and reverse and remand the portions of the judgments rendered in petitioners’ favor regarding enforcement and implementation of Measure E by Solano County, including petitioners’ recovery of costs, on mootness grounds.

On July 31, 2013, the Court of Appeal granted the Company’s motion and ruled that AB 845 preempted Measure E and therefore precluded the writ of mandate enforcing Measure E as judicially rewritten. The Court reversed the judgment and writ of mandate, and directed the trial court to dismiss the petitions. The Court also dismissed on mootness grounds the cross-appeals by the petitioners of the trial court’s denial of their request for a writ of mandate vacating the use permit for the expansion. Regarding the trial court’s award of attorney fees to the petitioners, the Court of Appeal stated that petitioners were no longer successful parties under California law and “the award of attorney fees must necessarily be reversed.” Because the appeal of the attorney fees award was a separate case from the merits appeal, the Court’s ruling did not include an order regarding the fees award. On August 19, 2013, the Company filed a Motion for Summary Reversal of Judgment Granting Attorney’s Fees in light of the Court of Appeal’s merits ruling, which the Court deferred until a remittitur was issued in the underlying merits appeal. On September 9, 2013, Sierra Club and SPRAWLDEF filed petitions for review of the Court of Appeal’s decision with the California Supreme Court. On October 23, 2013, the Supreme Court denied the petitions and issued a remittitur directing each party to bear its own costs on appeal. On January 22, 2014, the Court of Appeal granted the Company’s pending motion and reversed the attorney fee award. On January 23, 2014, the Solano County Superior Court dismissed the petitions filed by SPRAWLDEF, Sierra Club, and NCRA in accordance with the Court of Appeal’s decision, which officially concluded the litigation in the Company’s favor.

On December 17, 2010, SPRAWLDEF and one its members filed a petition for writ of mandate in San Francisco Superior Court seeking to overturn the October 2010 approval of the marsh development permit issued by the San Francisco Bay Conservation and Development Commission (“BCDC”) for PHLF’s landfill expansion, alleging that the approval is contrary to the Suisun Marsh Protection Act. The petition, captioned SPRAWLDEF v. San Francisco Bay Conservation and Development Commission, names BCDC as a respondent and the Company as the real party in interest. The San Francisco Superior Court stayed the action and, on April 5, 2012, transferred the case to Solano County Superior Court, citing that court’s experience in the related CEQA case and judicial economy. On June 5, 2012, Solano County Superior Court assigned the case to Judge Beeman. On November 29, 2012, the Superior Court issued an order finding that the administrative record before BCDC did not contain sufficient evidence regarding net profits for the proposed project or the alternative to support the agency’s finding that the alternative was economically infeasible. The Superior Court therefore issued a writ of mandamus and final judgment on January 14, 2013, setting aside the BCDC permit and remanding it back to the agency for further consideration. Both the Company and BCDC filed notices of appeal, staying execution of the writ and judgment pending the appeal. The Court of Appeal held oral argument on the appeal on February 4, 2014, and took the matter under submission. The County of Solano, Suisun Resource Conservation District, California Refuse Recycling Council and Napa-Vallejo Waste Management Authority each filed amici briefs in this case on behalf of Appellants BCDC and the Company. At this point the Company is not able to determine the likelihood of any outcome in this matter.

On June 10, 2011, June Guidotti, a property owner adjacent to PHLF, and SPRAWLDEF and one of its members, each filed administrative petitions for review with the State Water Resources Control Board (“State Board”) seeking to overturn a May 11, 2011 Order No. 2166-(a) approving waste discharge requirements issued by the San Francisco Bay Regional Water Quality Control Board (“Regional Board”) for PHLF’s landfill expansion, alleging that the order is contrary to the State Board’s Title 27 regulations authorizing waste discharge requirements for landfills, and in the case of the SPRAWLDEF petition, further alleging that the Regional Board’s issuance of a Clean Water Act section 401 certification is not supported by an adequate alternatives analysis as required by the federal Clean Water Act. The Regional Board is preparing the administrative record of its decision to issue Order 2166-(a) to be filed with the State Board as well as its response to the petitions for review. It is anticipated that the Regional Board will vigorously defend its actions and seek dismissal of the petitions for review. A hearing date has not yet been set on either petition, and the State Board has held both the Guidotti and SPRAWLDEF petitions in abeyance at the petitioners’ requests. At this point, the Company is not able to determine the likelihood of any outcome in this matter.

If as a result of any of the matters described above, after exhausting all appeals, PHLF’s marsh development permit is permanently rescinded, the Company estimates that it would be required to recognize a pre-tax impairment charge of approximately $11,000 to reduce the carrying value of PHLF to its estimated fair value.

Madera County, California Materials Recovery Facility Contract Litigation

The Company’s subsidiary, Madera Disposal Systems, Inc. (“MDSI”) was named in a complaint captioned County of Madera vs. Madera Disposal Systems, Inc., et al, filed in Madera County Superior Court (Case No. MCV 059402) on March 5, 2012, and subsequently transferred to Fresno County Superior Court. Madera County alleges in the complaint that from 2007 through 2010, MDSI breached a contract with the County for the operation of a materials recovery facility by withholding profits from facility operations in excess of those authorized by the contract. The County further alleges that the breach gives the County the unilateral right to terminate all of its contracts with MDSI, including contracts for (1) the collection of residential and commercial waste in the unincorporated parts of the County, (2) operation of the materials recovery facility, (3) operation of the North Fork Transfer Station and (4) operation of the Fairmead Landfill. The County seeks monetary damages of $2,962 from MDSI, plus pre-judgment interest at 10% per annum.

MDSI had been under contract with the County to collect residential and commercial waste and operate the county-owned Fairmead Landfill continuously since at least 1981. In 1993, MDSI contracted with the County to construct and operate a materials recovery facility for the County on the premises of the Fairmead Landfill. After it entered into the materials recovery facility contract, MDSI entered into new contracts with the County for waste collection and landfill operation to run concurrently with the materials recovery facility contract. In 1998, MDSI and the County agreed to extend the terms of the County contracts until November 10, 2012, with MDSI holding a unilateral option to extend the contracts for an additional five-year term.

In March 2011, the County issued a Notice of Default to MDSI under the materials recovery facility contract and gave MDSI 30 days to cure the default. MDSI provided information that it believed demonstrated that it was not in default under the contract and had not withheld profits that it was obligated to deliver to the County under the terms of the contract.

On February 7, 2012, the County issued a Notice of Termination to MDSI terminating all of its contracts effective November 1, 2012. The lawsuit followed on March 5, 2012. MDSI answered the complaint and asserted a claim against the County for wrongful termination of the contracts. On October 31, 2012, MDSI ceased providing services and vacated the County premises. The case is set for trial in Fresno in June 2014.

At this point, the Company is not able to determine the likelihood of any outcome in this matter. The Company disputes Madera County’s right to terminate the MDSI contracts effective November 1, 2012, and seeks damages for the profits lost as a result of the wrongful termination. The Company estimates that the current annual impact to its pre-tax earnings resulting from the termination of MDSI’s contracts with Madera County is approximately $2,300 per year, not including any monetary damages and interest the Court could order MDSI to pay the County.

Collective Bargaining Agreements 

Seven of the Company’s collective bargaining agreements have expired or are set to expire in 2014.  The Company does not expect any significant disruption in its overall business in 2014 as a result of labor negotiations, employee strikes or organizational efforts.

Cash Dividend

The Company’s Board of Directors authorized the initiation of a quarterly cash dividend in October 2010 and has increased it on an annual basis. In October 2013, the Company announced that its Board of Directors increased its regular quarterly cash dividend by $0.015, from $0.10 to $0.115 per share. Cash dividends of $51,213, $44,465 and $35,566 were paid during the years ended December 31, 2013, 2012 and 2011, respectively.

Share Repurchase Program 

The Company’s Board of Directors has authorized a common stock repurchase program for the repurchase of up to $1,200,000 of common stock through December 31, 2014.  Under the program, stock repurchases may be made in the open market or in privately negotiated transactions from time to time at management's discretion.  The timing and amounts of any repurchases will depend on many factors, including the Company's capital structure, the market price of the common stock and overall market conditions.  As of December 31, 2012, the Company had repurchased in aggregate 39,865,266 shares of its common stock at an aggregate cost of $784,040.  The Company did not repurchase any shares of its common stock during the year ended December 31, 2013. As of December 31, 2013, the remaining maximum dollar value of shares available for repurchase under the program was approximately $415,960.  The Company’s policy related to repurchases of its common stock is to charge any excess of cost over par value entirely to additional paid-in capital. 

Common Stock 

Of the 126,433,513 shares of common stock authorized but unissued as of December 31, 2013, the following shares were reserved for issuance:

Restricted Stock, Stock Options and Restricted Stock Units 

 In 2004, the Company’s Board of Directors authorized the 2004 Equity Incentive Plan. On May 7, 2010, the Company’s stockholders approved the latest amendment to the plan, now the Third Amended and Restated 2004 Equity Incentive Plan (the “2004 Equity Incentive Plan”). A total of 7,162,500 shares of the Company’s common stock were reserved for future issuance under the 2004 Equity Incentive Plan, all of which may be used for grants of stock options, restricted stock, and/or restricted stock units.  Participation in the 2004 Equity Incentive Plan is limited to employees, officers, directors and consultants.  Options granted under the 2004 Equity Incentive Plan are nonqualified stock options and have a term of no longer than five years from the date they are granted.  Restricted stock, restricted stock units, and options generally vest in installments pursuant to a vesting schedule set forth in each option or restricted stock or unit agreement.  The Board of Directors authorizes the granting of options, restricted stock and restricted stock units, and determines the employees and consultants to whom options, restricted stock, and restricted stock units are to be granted, the number of shares subject to each option, restricted stock, or restricted stock unit, the exercise price, term, vesting schedule and other terms and conditions of the options, restricted stock, or restricted stock units.  The exercise prices of the options shall not be less than the fair market value of the Company’s common stock on the date of grant.  Restricted stock awards under the plan may or may not require a cash payment from a participant to whom an award is made; restricted stock unit awards under the plan do not require any cash payment from the participant to whom an award is made.  The fair value of restricted stock units granted during the years ended December 31, 2013, 2012 and 2011, was determined based on the number of restricted stock units granted and the quoted price of the Company’s common stock on the date of grant.  As of December 31, 2013, 1,046,592 shares of common stock were available to be issued pursuant to future awards granted under the 2004 Equity Incentive Plan.

The differences between the Company’s income tax provision as presented in the accompanying Consolidated Statements of Net Income and income tax provision computed at the federal statutory rate consist of the items shown in the following table as a percentage of pre-tax income: 

	Years Ended December 31,
	2013			2012			2011
Income tax provision at the statutory rate		35.0	%		35.0	%		35.0	%

Noncontrolling interests		-			(0.1	)		(0.1	)
Other		0.2			0.3			0.6
		38.9	%		39.8	%		39.2	%

During the year ended December 31, 2012, the Deferred income tax liability adjustments, due primarily to changes in the geographical apportionment of the Company’s state income taxes associated with the R360 acquisition, resulted in an increase to tax expense of $2,602. 

At December 31, 2013 and 2012, the Company did not have any significant federal or state net operating loss carryforwards.  

The Company and its subsidiaries are subject to U.S. federal income tax as well as to income tax of multiple state jurisdictions.  The Company has concluded all U.S. federal income tax matters for years through 2009.  All material state and local income tax matters have been concluded for years through 2008. 

In September 2013, the U.S. Treasury Department issued final regulations governing the income tax treatment of acquisitions, dispositions, and repairs of tangible property, effective for tax years beginning in 2014.  The impact of these final regulations is not material to the Company’s financial statements.

The Company did not have any unrecognized tax benefits recorded at December 31, 2013 or 2012. The Company does not anticipate the total amount of unrecognized tax benefits will significantly change by December 31, 2014. The Company recognizes interest and/or penalties related to income tax matters in income tax expense.  

The following is a rollforward of the Company’s unrecognized tax benefits from January 1, 2011 to December 31, 2013:

Prior to October 2012, the Company managed its operations through three geographic operating segments (Western, Central and Eastern), which were also its reportable segments. In October 2012, as a result of the R360 acquisition described in Note 3, the Company realigned its reporting structure and created a fourth operating segment, the E&P segment, which includes the majority of the Company’s E&P waste treatment and disposal operations. As a result, the Company’s three geographic operating segments and its E&P segment comprise the Company’s reportable segments. Additionally, in January 2013, the Company transferred an E&P operation in Louisiana, owned by the Company prior to the R360 acquisition, from its Central segment to its E&P segment. Each operating segment is responsible for managing several vertically integrated operations, which are comprised of districts.  The segment information presented herein reflects the addition of the new E&P segment and the transfer of the Company’s E&P operation in Louisiana to the E&P segment. Under the current structure, the Company’s Western segment is comprised of operating locations in Alaska, California, Idaho, Montana, Nevada, Oregon, Washington and western Wyoming; the Company’s Central segment is comprised of operating locations in Arizona, Colorado, Kansas, Louisiana, Minnesota, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, Utah and eastern Wyoming; and the Company’s Eastern segment is comprised of operating locations in Alabama, Illinois, Iowa, Kentucky, Massachusetts, Michigan, Mississippi, New York, North Carolina, South Carolina and Tennessee. The E&P segment is comprised of the Company’s E&P operations in Louisiana, New Mexico, North Dakota, Oklahoma, Texas, Wyoming and along the Gulf of Mexico.

The Company’s Chief Operating Decision Maker (“CODM”) evaluates operating segment profitability and determines resource allocations based on several factors, of which the primary financial measure is EBITDA. The Company defines EBITDA as earnings before interest, taxes, depreciation, amortization, gain (loss) on disposal of assets, loss on prior office leases and other income (expense).  EBITDA is not a measure of operating income, operating performance or liquidity under generally accepted accounting principles and may not be comparable to similarly titled measures reported by other companies.  The Company’s management uses EBITDA in the evaluation of segment operating performance as it is a profit measure that is generally within the control of the operating segments.  A reconciliation of EBITDA to Income before income tax provision is included at the end of this Note 15.

Summarized financial information concerning the Company’s reportable segments for the years ended December 31, 2013, 2012 and 2011, is shown in the following tables:

17. EMPLOYEE BENEFIT PLANS

401K Plans: WCI has a voluntary savings and investment plan (the “WCI 401(k) Plan”), as do certain of its subsidiaries (together with the WCI 401(k) Plan, the “401(k) Plans”). The 401(k) Plans are available to all eligible employees of WCI and its subsidiaries. WCI and its subsidiaries make matching contributions under the 401(k) Plans of 50% to 100% of every dollar of a participating employee’s pre-tax contributions until the employee’s contributions equal from 3% to 6% of the employee’s eligible compensation, subject to certain limitations imposed by the U.S. Internal Revenue Code. 

Total employer expenses, including employer matching contributions, for the 401(k) Plans were $4,024, $3,304 and $2,759, respectively, during the years ended December 31, 2013, 2012 and 2011.  These amounts include matching contributions WCI made under the Deferred Compensation Plan, described below. 

Multiemployer Pension Plans: The Company also participates in two “multiemployer” pension plans. The Company does not administer these multiemployer plans. In general, these plans are managed by the trustees, with the unions appointing certain trustees, and other contributing employers of the plan appointing certain members. The Company is generally not represented on the board of trustees.  The Company makes periodic contributions to these plans pursuant to its collective bargaining agreements.  The Company’s participation in multiemployer pension plans is summarized as follows:

(a) There is one collective bargaining agreement, representing 15 employees, which expired on December 31, 2013, and is currently being negotiated for extension.

(b) The most recent Pension Protection Act zone status available in 2013 and 2012 is for the plans’ years ended December 31, 2012 and 2011, respectively.

The status is based on information that the Company received from the pension plans and is certified by the pension plans’ actuary. Plans with “green” status are at least 80% funded. The Company’s contributions to each individual multiemployer pension plan represent less than 5% of total contributions to such plan. Under current law regarding multiemployer benefit plans, a plan’s termination, the Company’s voluntary withdrawal, or the withdrawal of all contributing employers from any under-funded multiemployer pension plan would require the Company to make payments to the plan for its proportionate share of the multiemployer plan’s unfunded vested liabilities. The Company could have adjustments to its estimates for these matters in the near term that could have a material effect on its consolidated financial condition, results of operations or cash flows.

Deferred Compensation Plan: Effective for compensation paid on and after July 1, 2004, the Company established a Deferred Compensation Plan for eligible employees, which was amended and restated effective January 1, 2008, January 1, 2010 and January 1, 2014 (the “Deferred Compensation Plan”).  The Deferred Compensation Plan is a non-qualified deferred compensation program under which the eligible participants, including officers and certain employees who meet a minimum salary threshold, may voluntarily elect to defer up to 80% of their base salaries and up to 100% of their bonuses, commissions and restricted stock unit grants.  Members of the Company’s Board of Directors are eligible to participate in the Deferred Compensation Plan with respect to their Director fees.  Although the Company periodically contributes the amount of its obligation under the plan to a trust for the benefit of the participants, the amounts of any compensation deferred under the Deferred Compensation Plan constitute an unsecured obligation of the Company to pay the participants in the future and, as such, are subject to the claims of other creditors in the event of insolvency proceedings.  Participants may elect certain future distribution dates on which all or a portion of their accounts will be paid to them, including in the case of a change in control of the Company.  Their accounts will be distributed to them in cash, except for amounts credited with respect to deferred restricted stock unit grants, which will be distributed in shares of the Company’s common stock pursuant to the Third Amended and Restated 2004 Equity Incentive Plan or any successor plan or plans.  In addition to the amount of participants’ contributions, the Company will pay participants an amount reflecting a deemed return based on the returns of various mutual funds or measurement funds selected by the participants, except in the case of restricted stock units that are deferred, which are credited to their accounts as shares of Company common stock.  The measurement funds are used only to determine the amount of return the Company pays to participants and participant funds are not actually invested in the measurement fund, nor are any shares of Company common stock acquired under the Deferred Compensation Plan.  In each of the three years ending December 31, 2013, the Company also made matching contributions to the Deferred Compensation Plan of 50% of every dollar of a participating employee’s pre-tax eligible contributions until the employee’s contributions equal 5% of the employee’s eligible compensation, less the amount of any match the Company makes on behalf of the employee under the WCI 401(k) Plan, and subject to certain deferral limitations imposed by the U.S. Internal Revenue Code on 401(k) plans, except that the Company’s matching contributions under the Deferred Compensation Plan were 100% vested when made.  The Company’s total liability for deferred compensation at December 31, 2013 and 2012 was $15,335 and $12,541, respectively, which was recorded in Other long-term liabilities in the Consolidated Balance Sheets.

ITEM 9A.    CONTROLS AND PROCEDURES

Disclosure Controls and Procedures 

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended.  Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of December 31, 2013, at the reasonable assurance level such that information required to be disclosed in our Exchange Act reports:  (1) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms; and (2) is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. 

Management’s Report on Internal Control over Financial Reporting 

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended.  Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles.  This process includes policies and procedures that:  (1) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect our transactions and any dispositions of our assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles; (3) provide reasonable assurance that receipts and expenditures of ours are being made only in accordance with authorizations of our management; and (4) provide reasonable assurance that unauthorized acquisition, use or disposition of our assets that could have a material affect on our financial statements would be prevented or timely detected. 

We carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our internal control over financial reporting as of December 31, 2013.  In conducting our evaluation, we used the 1992 framework set forth in the report titled “Internal Control – Integrated Framework (1992)” published by the Committee of Sponsoring Organizations of the Treadway Commission.  Based on the results of our evaluation, our management has concluded that our internal control over financial reporting was effective as of December 31, 2013. 

The effectiveness of our internal control over financial reporting as of December 31, 2013, has been audited by PricewaterhouseCoopers LLP, our independent registered public accounting firm, as stated in its report which appears in Item 8 of this Annual Report on Form 10-K. 

Changes in Internal Control Over Financial Reporting 

Based on an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, there has been no change to our internal control over financial reporting that occurred during the three month period ended December 31, 2013, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

AMENDMENT

TO THE

WASTE CONNECTIONS, INC.

NONQUALIFIED DEFERRED COMPENSATION PLAN

Waste Connections, Inc. (the "Company") wishes to amend the Waste Connections, Inc. Nonqualified Deferred Compensation Plan (the "Plan"). This Amendment is intended to amend the Plan’s distribution features with respect to amounts attributable to contributions to the Plan made after 2013, and to clarify certain other features of the Plan.

Accordingly, effective January 1, 2014, the Plan is amended as follows:

1. In recognition of the fact that the Plan currently accords a Retirement Benefit the same treatment for benefit distribution purposes as a Termination Benefit, the provisions of the Plan addressing a Retirement Benefit are removed, as follows: Sections 1.39 and 1.40 and Article 6 are removed, as are all references in the Plan to “Retirement,” “Retire(s),” “Retired” and “Retirement Benefit;” and the Section and Article references in the Plan document requiring adjustment to reflect such removals are so adjusted. For the avoidance of doubt, the removal of provisions of the Plan addressing Retirement Benefits shall not modify outstanding deferral elections related to Retirement Benefits in effect as of the effective date of this Amendment, which deferral elections shall continue in full force and effect, without modification.

2. The final sentence of Section 1.42(c) is replaced with the following sentence:

Notwithstanding the foregoing, if a Participant provides services to an Employer

as both an Employee and a member of the Board, the services provided as a director are not taken into account in determining whether a Participant has a Separation from Service as an Employee for purposes of this Plan, and the services provided as an Employee are not taken into account in determining whether a Participant has a Separation from Service as a Director for purposes of this Plan (i.e., a Participant who experiences a Separation from Service as an Employee, determined in accordance with the provisions set forth in part (a) of this Section, shall be deemed to have experienced a Separation from Service with respect to the portion of his or her Account Balance attributable to his or her services as an Employee, notwithstanding the Participant’s continued service to the Board).

3. Section 3.9(f) is replaced with the following:

(f) Stock Equivalent Account. Any amounts credited to a Participant’s Stock Equivalent Account are to be used for measurement purposes only. The amounts allocated to a Participant’s Stock Equivalent Account, any Account Balance therein, or any additional amounts credited or debited to a Participant’s Stock Equivalent Account shall not be considered or construed in any manner as an actual investment of his or her Account Balance in any shares of the Company’s Common Stock. Fractional common stock equivalents shall be computed to two decimal places. The number of common stock equivalent shares to be credited to the Stock Equivalent Account shall be the number of shares of Common Stock which would otherwise have been payable under the Restricted Stock Unit Award to the Participant on or after the vesting date but as to which the Participant has elected to defer delivery pursuant to the terms of the Plan, less any amounts withheld pursuant to Section 3.10. With respect to any dividends or dividend equivalents made with respect to common stock equivalent shares deferred pursuant to Restricted Stock Unit Awards, an amount equal to such number of common stock equivalent shares in the account as of the dividend record date multiplied by the dividend paid per share on the Company’s common stock on each dividend record date shall be credited to the Participant’s Deferral Account and allocated into Measurement Funds pursuant to the terms and conditions that relate to Measurement Funds in Sections 3.9(a) through 3.9(e). Except as the Committee may otherwise permit upon request of the Participant, the number of shares of the Company’s Common Stock to be paid to a Participant upon a distribution with respect to the Stock Equivalent Account shall be equal to the number of common stock equivalent shares deferred pursuant to Restricted Stock Unit Awards (as appropriately adjusted in the Committee’s sole discretion, in the event of any change in the number or kind of outstanding shares of the Company’s Common Stock, including a stock split or splits) divided by the total number of payments remaining to be made from the Stock Equivalent Account. Shares of Common Stock paid in respect of a Restricted Stock Unit Award shall be issued and delivered pursuant to the Waste Connections, Inc. Third Amended and Restated 2004 Equity Incentive Plan (or such successor incentive stock plan of the Company as is in effect at the time of the award) as an award thereunder and such distributions or payments shall be subject to the terms and conditions of such plan (or plans) and any award agreements evidencing the applicable Restricted Stock Unit Awards. All payments of the Company’s Common Stock from the Stock Equivalent Account shall be made in whole shares of the Company’s common stock with fractional shares credited to federal income taxes withheld.

Notwithstanding anything to the contrary in the foregoing, any portion of the Stock Equivalent Account other than the common stock equivalent shares deferred pursuant to Restricted Stock Unit Awards shall be credited to the Participant’s Deferral Account on each crediting date, as applicable, and allocated into the Stock Equivalent Account (the “Stock Equivalent Account Balance”); provided, however, that the Stock Equivalent Account Balance shall be credited to the Stock Equivalent Account in cash, without interest or other earnings. The Stock Equivalent Account Balance shall be paid in cash in an amount equal to the Stock Equivalent Account Balance, divided by the total number of payments remaining to be made from the Stock Equivalent Account.

2

Notwithstanding the preceding, except if and to the extent that the Company’s Third Amended and Restated 2004 Equity Incentive Plan (or any successor incentive stock plan) or any award agreement thereunder provides otherwise, and subject to any procedures that are established by the Committee and further subject to applicable law, including Code Section 409A and related Treasury guidance and Regulations, a Participant may elect with respect to any distribution to which he or she becomes entitled hereunder the deemed investment(s) (i.e., the Measurement Fund(s) or the Stock Equivalent Account) that the Participant wishes to decrease to reflect the debiting of the Participant’s Account Balance by the amount of such distribution.

4. The first sentence of Section 4.1(a) is replaced with the following sentences:

In connection with each election to defer an Annual Deferral Amount for a given Plan Year, a Participant may elect on an Election Form to receive a Scheduled Distribution from the Plan, in the form of a lump sum payment, with respect to all or a portion of that Plan Year’s (i) Annual Deferral Amount, (ii) Company Contribution Amount, and (iii) Company Restoration Matching Amount, and earnings or losses thereon. The Participant must affirmatively make such election for each Plan Year in order to receive a Scheduled Distribution with respect to that Plan Year’s deferrals and contributions (i.e., an election made in one Plan Year will not “evergreen” for any future Plan Year), which election must be made by the deadline(s) set forth in Section 3.3 for making a deferral election in respect to that Plan Year (whether or not the Participant actually makes a deferral election in respect to that Plan Year), and which election, except as provided in Section 4.2, is irrevocable after that deadline has passed. If a Participant does not timely make an affirmative election in respect to a Plan Year, then such Participant shall be deemed to have irrevocably elected not to receive a Scheduled Distribution in respect of that Plan Year.

5. The first sentence of Section 5.2 is replaced with the following sentences:

In connection with each election to defer an Annual Deferral Amount for a given Plan Year, a Participant shall elect on an Election Form to receive a Change in Control Benefit from the Plan with respect to all or a portion of that Plan Year’s (i) Annual Deferral Amount, (ii) Company Contribution Amount, and (iii) Company Restoration Matching Amount, and earnings or losses thereon, or to have those amounts remain in the Plan upon the occurrence of a Change in Control and remain subject to the terms and conditions of the Plan. Except as provided in the following sentence, the Participant must affirmatively make such election for each Plan Year (i.e., an election made in one Plan Year will not “evergreen” for any future Plan Year), which election must be made by the deadline(s) set forth in Section 3.3 for making a deferral election in respect to that Plan Year (whether or not the Participant actually makes a deferral election in respect to that Plan Year), and which election is irrevocable after that deadline has passed.

3

6. Section 6.2(a) (formerly Section 7.2(a)) is replaced with the following:

In connection with each election to defer an Annual Deferral Amount for a given Plan Year, a Participant shall elect on an Election Form to receive a Termination Benefit from the Plan, in the form of a lump sum payment or pursuant to an Annual Installment Method of up to 15 years, with respect to all or a portion of that Plan Year’s (i) Annual Deferral Amount, (ii) Company Contribution Amount, and (iii) Company Restoration Matching Amount, and earnings or losses thereon. Except as provided in the following sentence, the Participant must affirmatively make such election for each Plan Year (i.e., an election made in one Plan Year will not “evergreen” for any future Plan Year), which election must be made by the deadline(s) set forth in Section 3.3 for making a deferral election in respect to that Plan Year (whether or not the Participant actually makes a deferral election in respect to that Plan Year), and which election, except as provided in Section 6.2(b), is irrevocable after that deadline has passed. If a Participant does not timely make an affirmative election with respect to the payment of the Termination Benefit in respect of a Plan Year, then such Participant shall be deemed to have irrevocably elected (except as provided in Section 6.2(b)) to receive the Termination Benefit in a lump sum.

IN WITNESS WHEREOF, the Company has caused this Amendment to be executed effective as of January 1, 2014.

Employee Benefit Plans

17.EMPLOYEE BENEFIT PLANS

401K Plans: WCI has a voluntary savings and investment plan (the “WCI 401(k) Plan”), as do certain of its subsidiaries (together with the WCI 401(k) Plan, the “401(k) Plans”).  The 401(k) Plans are available to all eligible employees of WCI and its subsidiaries.  WCI and its subsidiaries make matching contributions under the 401(k) Plans of 50% to 100% of every dollar of a participating employee’s pre-tax contributions until the employee’s contributions equal from 3% to 6% of the employee’s eligible compensation, subject to certain limitations imposed by the U.S. Internal Revenue Code. 

Total employer expenses, including employer matching contributions, for the 401(k) Plans were $4,024,  $3,304 and $2,759, respectively, during the years ended December 31, 2013, 2012 and 2011.  These amounts include matching contributions WCI made under the Deferred Compensation Plan, described below. 

Multiemployer Pension Plans: The Company also participates in two “multiemployer” pension plans.  The Company does not administer these multiemployer plans.  In general, these plans are managed by the trustees, with the unions appointing certain trustees, and other contributing employers of the plan appointing certain members.  The Company is generally not represented on the board of trustees.  The Company makes periodic contributions to these plans pursuant to its collective bargaining agreements.  The Company’s participation in multiemployer pension plans is summarized as follows:

(a) There is one collective bargaining agreement, representing 15 employees, which expired on December 31, 2013, and is currently being negotiated for extension.

(b) The most recent Pension Protection Act zone status available in 2013 and 2012 is for the plans’ years ended December 31, 2012 and 2011, respectively.

The status is based on information that the Company received from the pension plans and is certified by the pension plans’ actuary. Plans with “green” status are at least 80% funded.  The Company’s contributions to each individual multiemployer pension plan represent less than 5% of total contributions to such plan.  Under current law regarding multiemployer benefit plans, a plan’s termination, the Company’s voluntary withdrawal, or the withdrawal of all contributing employers from any under-funded multiemployer pension plan would require the Company to make payments to the plan for its proportionate share of the multiemployer plan’s unfunded vested liabilities.  The Company could have adjustments to its estimates for these matters in the near term that could have a material effect on its consolidated financial condition, results of operations or cash flows.

Deferred Compensation Plan:  Effective for compensation paid on and after July 1, 2004, the Company established a Deferred Compensation Plan for eligible employees, which was amended and restated effective January 1, 2008, January 1, 2010 and January 1, 2014 (the “Deferred Compensation Plan”).  The Deferred Compensation Plan is a non-qualified deferred compensation program under which the eligible participants, including officers and certain employees who meet a minimum salary threshold, may voluntarily elect to defer up to 80% of their base salaries and up to 100% of their bonuses, commissions and restricted stock unit grants.  Members of the Company’s Board of Directors are eligible to participate in the Deferred Compensation Plan with respect to their Director fees.  Although the Company periodically contributes the amount of its obligation under the plan to a trust for the benefit of the participants, the amounts of any compensation deferred under the Deferred Compensation Plan constitute an unsecured obligation of the Company to pay the participants in the future and, as such, are subject to the claims of other creditors in the event of insolvency proceedings.  Participants may elect certain future distribution dates on which all or a portion of their accounts will be paid to them, including in the case of a change in control of the Company.  Their accounts will be distributed to them in cash, except for amounts credited with respect to deferred restricted stock unit grants, which will be distributed in shares of the Company’s common stock pursuant to the Third Amended and Restated 2004 Equity Incentive Plan or any successor plan or plans.  In addition to the amount of participants’ contributions, the Company will pay participants an amount reflecting a deemed return based on the returns of various mutual funds or measurement funds selected by the participants, except in the case of restricted stock units that are deferred, which are credited to their accounts as shares of Company common stock.  The measurement funds are used only to determine the amount of return the Company pays to participants and participant funds are not actually invested in the measurement fund, nor are any shares of Company common stock acquired under the Deferred Compensation Plan.  In each of the three years ending December 31, 2013, the Company also made matching contributions to the Deferred Compensation Plan of 50% of every dollar of a participating employee’s pre-tax eligible contributions until the employee’s contributions equal 5% of the employee’s eligible compensation, less the amount of any match the Company makes on behalf of the employee under the WCI 401(k) Plan, and subject to certain deferral limitations imposed by the U.S. Internal Revenue Code on 401(k) plans, except that the Company’s matching contributions under the Deferred Compensation Plan were 100% vested when made.  The Company’s total liability for deferred compensation at December 31, 2013 and 2012 was $15,335 and $12,541, respectively, which was recorded in Other long-term liabilities in the Consolidated Balance Sheets.

[1] In accordance with the derivatives and hedging guidance, the effective portions of the changes in fair values of interest rate swaps and the fuel hedge have been recorded in equity as a component of AOCL.  As the critical terms of the interest rate swaps match the underlying debt being hedged, no ineffectiveness is recognized on these swaps and, therefore, all unrealized changes in fair value are recorded in AOCL.  Because changes in the actual price of diesel fuel and changes in the DOE index price do not offset exactly each reporting period, the Company assesses whether the fuel hedge is highly effective using the cumulative dollar offset approach.

[2] Amounts reclassified from AOCL into earnings related to realized gains and losses on interest rate swaps are recognized when interest payments or receipts occur related to the swap contracts, which correspond to when interest payments are made on the Company’s hedged debt.

[3] Amounts reclassified from AOCL into earnings related to realized gains and losses on the fuel hedge are recognized when settlement payments or receipts occur related to the hedge contract, which correspond to when the underlying fuel is consumed.

Organization, Business and Summary of Significant Accounting Policies

1.ORGANIZATION, BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

Organization and Business

Waste Connections, Inc. (“WCI” or the “Company”) was incorporated in Delaware on September 9, 1997, and commenced its operations on October 1, 1997, through the purchase of certain solid waste operations in the state of Washington.  The Company is an integrated municipal solid waste services company that provides solid waste collection, transfer, disposal and recycling services in mostly exclusive and secondary markets in the U.S. and a leading provider of non-hazardous exploration and production (“E&P”) waste treatment, recovery and disposal services in several of the most active natural resource producing areas of the U.S.  The Company also provides intermodal services for the rail haul movement of cargo and solid waste containers in the Pacific Northwest.

Basis of Presentation 

These consolidated financial statements include the accounts of WCI and its wholly-owned and majority-owned subsidiaries.  The consolidated entity is referred to herein as the Company.  All significant intercompany accounts and transactions have been eliminated in consolidation. 

Cash Equivalents 

The Company considers all highly liquid investments with a maturity of three months or less at purchase to be cash equivalents.  As of December 31, 2013 and 2012, cash equivalents consisted of demand money market accounts.

Concentrations of Credit Risk 

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and equivalents, restricted assets and accounts receivable.  The Company maintains cash and 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’s restricted assets are invested primarily in U.S. government and agency securities.  The Company has not experienced any losses related to its cash and equivalents or restricted asset 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.  The Company maintains allowances for losses based on the expected collectability of accounts receivable. 

Revenue Recognition and Accounts Receivable 

Revenues are recognized when persuasive evidence of an arrangement exists, the service has been provided, the price is fixed or determinable and collection is reasonably assured.  Certain customers are billed in advance and, accordingly, recognition of the related revenues is deferred until the services are provided.  In accordance with revenue recognition guidance, any tax assessed by a governmental authority that is directly imposed on a revenue-producing transaction between a seller and a customer is presented in the statements of net income on a net basis (excluded from revenues). 

The Company’s receivables are recorded when billed or accrued and represent claims against third parties that will be settled in cash.  The carrying value of the Company’s receivables, net of the allowance for doubtful accounts, represents their estimated net realizable value.  The Company estimates its allowance for doubtful accounts based on historical collection trends, type of customer such as municipal or non-municipal, the age of outstanding receivables 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 and the allowance is adjusted accordingly.  Past-due receivable balances are written off when the Company’s internal collection efforts have been unsuccessful in collecting the amount due. 

Property and Equipment 

Property and equipment are stated at cost.  Improvements or betterments, not considered to be maintenance and repair, which add new functionality or significantly extend the life of an asset are capitalized.  Third-party expenditures related to pending development projects, such as legal and engineering expenses, are capitalized.  Expenditures for maintenance and repair costs, including planned major maintenance activities, are charged to expense as incurred.  The cost of assets retired or otherwise disposed of and the related accumulated depreciation are eliminated from the accounts in the year of disposal.  Gains and losses resulting from disposals of property and equipment are recognized in the period in which the property and equipment is disposed.  Depreciation is computed using the straight-line method over the estimated useful lives of the assets or the lease term, whichever is shorter. 

The estimated useful lives are as follows: 

Buildings	10 – 20 years
Leasehold and land improvements	3 – 10 years
Machinery and equipment	3 – 12 years
Rolling stock	2 – 10 years
Containers	5 – 12 years
Rail cars	20 years

Landfill Accounting

The Company utilizes the life cycle method of accounting for landfill costs.  This method applies the costs to be capitalized associated with acquiring, developing, closing and monitoring the landfills over the associated consumption of landfill capacity.  The Company utilizes the units of consumption method to amortize landfill development costs over the estimated remaining capacity of a landfill.  Under this method, the Company includes future estimated construction costs using current dollars, as well as costs incurred to date, in the amortization base.  When certain criteria are met, the Company includes expansion airspace, which has not been permitted, in the calculation of the total remaining capacity of the landfill. 

- Landfill development costs.  Landfill development costs include the costs of acquisition, construction associated with excavation, liners, site berms, groundwater monitoring wells, gas recovery systems and leachate collection systems.  The Company estimates the total costs associated with developing each landfill site to its final capacity.  This includes certain projected landfill site costs that are uncertain because they are dependent on future events and thus actual costs could vary significantly from estimates.  The total cost to develop a site to its final capacity includes amounts previously expended and capitalized, net of accumulated depletion, and projections of future purchase and development costs, liner construction costs, and operating construction costs.  Total landfill costs include the development costs associated with expansion airspace.  Expansion airspace is addressed below. 

- Final capping, closure and post-closure obligations.  The Company accrues for estimated final capping, closure and post-closure maintenance obligations at the landfills it owns and five of the six landfills that it operates, but does not own under life-of-site agreements.  Accrued final capping, closure and post-closure costs represent an estimate of the current value of the future obligation associated with final capping, closure and post-closure monitoring of non-hazardous solid waste landfills currently owned or operated under life-of-site agreements by the Company.  Final capping costs represent the costs related to installation of clay liners, drainage and compacted soil layers and topsoil constructed over areas of the landfill where total airspace capacity has been consumed.  Closure and post-closure monitoring and maintenance costs represent the costs related to cash expenditures yet to be incurred when a landfill facility ceases to accept waste and closes.  Accruals for final capping, closure and post-closure monitoring and maintenance requirements in the U.S. consider site inspection, groundwater monitoring, leachate management, methane gas control and recovery, and operating and maintenance costs to be incurred during the period after the facility closes.  Certain of these environmental costs, principally capping and methane gas control costs, are also incurred during the operating life of the site in accordance with the landfill operation requirements of Subtitle D and the air emissions standards.  Daily maintenance activities, which include many of these costs, are expensed as incurred during the operating life of the landfill.  Daily maintenance activities include leachate disposal; surface water, groundwater, and methane gas monitoring and maintenance; other pollution control activities; mowing and fertilizing the landfill final cap; fence and road maintenance; and third-party inspection and reporting costs.  Site specific final capping, closure and post-closure engineering cost estimates are prepared annually for landfills owned or landfills operated under life-of-site agreements by the Company for which it is responsible for final capping, closure and post-closure. 

The net present value of landfill final capping, closure and post-closure liabilities are calculated by estimating the total obligation in current dollars, inflating the obligation based upon the expected date of the expenditure and discounting the inflated total to its present value using a credit-adjusted risk-free rate.  Any changes in expectations that result in an upward revision to the estimated undiscounted cash flows are treated as a new liability and are inflated and discounted at rates reflecting current market conditions.  Any changes in expectations that result in a downward revision (or no revision) to the estimated undiscounted cash flows result in a liability that is inflated and discounted at rates reflecting the market conditions at the time the cash flows were originally estimated.  This policy results in the Company’s final capping, closure and post-closure liabilities being recorded in “layers.”  The Company’s discount rate assumption for purposes of computing 2013 and 2012 “layers” for final capping, closure and post-closure obligations was 5.75% for each year, which reflects the Company’s long-term cost of borrowing as of the end of 2012 and 2011.  The Company’s inflation rate assumption was 2.5% for the years ended December 31, 2013 and 2012.  

In accordance with the accounting guidance on asset retirement obligations, the final capping, closure and post-closure liability is recorded on the balance sheet along with an offsetting addition to site costs which is amortized to depletion expense on a units-of-consumption basis as remaining landfill airspace is consumed.  The impact of changes determined to be changes in estimates, based on an annual update, is accounted for on a prospective basis.  Depletion expense resulting from final capping, closure and post-closure obligations recorded as a component of landfill site costs will generally be less during the early portion of a landfill’s operating life and increase thereafter.  Owned landfills and landfills operated under life-of-site agreements have estimated remaining lives, based on remaining permitted capacity, probable expansion capacity and projected annual disposal volumes, that range from approximately 5to 200 years, with an average remaining life of approximately 42years.  The costs for final capping, closure and post-closure obligations at landfills the Company owns or operates under life-of-site agreements are generally estimated based on interpretations of current requirements and proposed or anticipated regulatory changes. 

The estimates for landfill final capping, closure and post-closure costs consider when the costs would actually be paid and factor in inflation and discount rates.  Interest is accreted on the recorded liability using the corresponding discount rate.  When using discounted cash flow techniques, reliable estimates of market premiums may not be obtainable.  In the waste industry, there is no market for selling the responsibility for final capping, closure and post-closure obligations independent of selling the landfill in its entirety.  Accordingly, the Company does not believe that it is possible to develop a methodology to reliably estimate a market risk premium and has therefore excluded any such market risk premium from its determination of expected cash flows for landfill asset retirement obligations.  The possibility of changing legal and regulatory requirements and the forward-looking nature of these types of costs make any estimation or assumption less certain. 

The following is a reconciliation of the Company’s final capping, closure and post-closure liability balance from December 31, 2011 to December 31, 2013: 

Final capping, closure and post-closure liability at December 31, 2011	$	30,883
Adjustments to final capping, closure and post-closure liabilities		3,535
Liabilities incurred		2,926
Accretion expense associated with landfill obligations		2,581
Closure payments		(22)
Assumption of closure liabilities from acquisitions		6,570
Final capping, closure and post-closure liability at December 31, 2012		46,473
Adjustments to final capping, closure and post-closure liabilities		(3,528)
Liabilities incurred		4,668
Accretion expense associated with landfill obligations		2,749
Closure payments		(234)
Final capping, closure and post-closure liability at December 31, 2013	$	50,128

The Adjustments to final capping, closure and post-closure liabilities for the year ended December 31, 2013, primarily consisted of increases in estimated airspace at some of the Company’s landfills at which expansions are being pursued or have been granted, decreases in estimated closure costs at some of the Company’s landfills and revisions in engineering estimates, partially offset by an increase in estimates of annual tonnage consumption at some of the Company’s landfills.  The Adjustments to final capping, closure and post-closure liabilities for the year ended December 31, 2012, primarily consisted of increases in estimated closure costs and changes in timing of closure activities at some of the Company’s landfills, partially offset by a decrease in closure liabilities from third parties due to changes in timing of closure activities and reduced closure expenses.  The final capping, closure and post-closure liability is included in Other long-term liabilities in the Consolidated Balance Sheets.  The Company performs its annual review of its cost and capacity estimates in the first quarter of each year. 

At December 31, 2013, $33,466 of the Company’s restricted assets balance was for purposes of securing its performance of future final capping, closure and post-closure obligations. 

- Disposal capacity.  The Company’s internal and third-party engineers perform surveys at least annually to estimate the remaining disposal capacity at its landfills.  This is done by using surveys and other methods to calculate, based on the terms of the permit, height restrictions and other factors, how much airspace is left to fill and how much waste can be disposed of at a landfill before it has reached its final capacity.  The Company’s landfill depletion rates are based on the remaining disposal capacity, considering both permitted and probable expansion airspace, at the landfills it owns, and certain landfills it operates, but does not own, under life-of-site agreements.  The Company’s landfill depletion rate is based on the term of the operating agreement at its operated landfill that has capitalized expenditures.  Expansion airspace consists of additional disposal capacity being pursued through means of an expansion that has not yet been permitted.  Expansion airspace that meets the following criteria is included in the estimate of total landfill airspace: 

1) whether the land where the expansion is being sought is contiguous to the current disposal site, and the Company either owns the expansion property or has rights to it under an option, purchase, operating or other similar agreement; 

2) whether total development costs, final capping costs, and closure/post-closure costs have been determined; 

3) whether internal personnel have performed a financial analysis of the proposed expansion site and have determined that it has a positive financial and operational impact; 

4) whether internal personnel or external consultants are actively working to obtain the necessary approvals to obtain the landfill expansion permit; and 

5) whether the Company considers it probable that the Company will achieve the expansion (for a pursued expansion to be considered probable, there must be no significant known technical, legal, community, business, or political restrictions or similar issues existing that the Company believes are more likely than not to impair the success of the expansion). 

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, as described below, 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 Company periodically evaluates its landfill sites for potential impairment indicators.  The Company’s judgments regarding the existence of impairment indicators are based on regulatory factors, market conditions and operational performance of its landfills.  Future events could cause the Company to conclude that impairment indicators exist and that its landfill carrying costs are impaired. 

Cell Processing Reserves

The Company records a cell processing reserve related to its E&P segment for certain locations in Louisiana and Texas for the estimated amount of expenses to be incurred upon the treatment and excavation of oilfield waste received.  The cell processing reserve is the future cost to properly treat and dispose of existing waste within the cells at the various facilities.  The reserve generally covers estimated costs to be incurred over a period of time up to 24 months, with the current portion representing costs estimated to be incurred in the next 12 months.  The estimate is calculated based on current estimated volume in the cells, estimated percentage of waste treated, and historical average costs to treat and excavate the waste.  The processing reserve represents the estimated costs to process the volumes of oilfield waste on-hand for which revenue has been recognized.  At December 31, 2013 and 2012, the current portion of cell processing reserves was $7,013 and $6,442, respectively, which is included in Accrued liabilities in the Consolidated Balance Sheets. At December 31, 2013 and 2012, the long-term portion of cell processing reserves was $2,416 and $2,043, respectively, which is included in Other long-term liabilities in the Consolidated Balance Sheets.

Business Combination Accounting

The Company accounts for business combinations as follows: 

· The Company recognizes, separately from goodwill, the identifiable assets acquired and liabilities assumed at their estimated acquisition date fair values.  The Company measures and recognizes goodwill as of the acquisition date as the excess of:  (a) the aggregate of the fair value of consideration transferred, the fair value of any noncontrolling interest in the acquiree (if any) and the acquisition date fair value of the Company’s previously held equity interest in the acquiree (if any), over (b) the fair value of net assets acquired and liabilities assumed. 

· At the acquisition date, the Company measures the fair values of all assets acquired and liabilities assumed that arise from contractual contingencies.  The Company measures the fair values of all noncontractual contingencies if, as of the acquisition date, it is more likely than not that the contingency will give rise to an asset or liability. 

Finite-Lived Intangible Assets

The amounts assigned to franchise agreements, contracts and customer listsare being amortized on a straight-line basis over the expected term of the related agreements (ranging from 1 to 56 years). 

Goodwill and Indefinite-Lived Intangible Assets 

The Company acquired indefinite-lived intangible assets in connection with certain of its acquisitions.  The amounts assigned to indefinite-lived intangible assets consist of the value of certain perpetual rights to provide solid waste collection and transportation services in specified territories and to operate exploration and production waste treatment and disposal facilities.  The Company measures and recognizes acquired indefinite-lived intangible assets at their estimated acquisition date fair values.  Indefinite-lived intangible assets are not amortized.  Goodwill represents the excess of:  (a) the aggregate of the fair value of consideration transferred, the fair value of any noncontrolling interest in the acquiree (if any) and the acquisition date fair value of the Company’s previously held equity interest in the acquiree (if any), over (b)  the fair value of assets acquired and liabilities assumed.  Goodwill and intangible assets, deemed to have indefinite lives, are subject to annual impairment tests as described below. 

Goodwill and indefinite-lived intangible assets are tested for impairment on at least an annual basis in the fourth quarter of the year. In the first step of testing for goodwill impairment, the Company estimates the fair value of each reporting unit, which the Company has determined to be its three geographic operating segments and its E&P segment, and compares the fair value with the carrying value of the net assets assigned to each reporting unit.  If the fair value of a reporting unit is greater than the carrying value of the net assets, including goodwill, assigned to the reporting unit, then no impairment results.  If the fair value is less than the carrying value, then the Company would perform a second step and determine the fair value of the goodwill.  In this second step, the fair value of goodwill is determined by deducting the fair value of a reporting unit’s identifiable assets and liabilities from the fair value of the reporting unit as a whole, as if that reporting unit had just been acquired and the purchase price were being initially allocated.  If the fair value of the goodwill is less than its carrying value for a reporting unit, an impairment charge would be recorded to earnings in the Company’s Consolidated Statements of Net Income.  In testing indefinite-lived intangible assets for impairment, the Company compares the estimated fair value of each indefinite-lived intangible asset to its carrying value.  If the fair value of the indefinite-lived intangible asset is less than its carrying value, an impairment charge would be recorded to earnings in the Company’s Consolidated Statements of Net Income. 

To determine the fair value of each of the Company’s reporting units as a whole and each indefinite-lived intangible asset, the Company uses discounted cash flow analyses, which require significant assumptions and estimates about the future operations of each reporting unit and the future discrete cash flows related to each indefinite-lived intangible asset.  Significant judgments inherent in these analyses include the determination of appropriate discount rates, the amount and timing of expected future cash flows and growth rates.  The cash flows employed in the Company’s 2013 discounted cash flow analyses were based on ten-year financial forecasts, which in turn were based on the 2014 annual budget developed internally by management.  These forecasts reflect operating profit margins that were consistent with 2013 results and perpetual revenue growth rates of 3.2%.  The Company’s discount rate assumptions are based on an assessment of the Company’s weighted average cost of capital which approximated 5.4%.  In assessing the reasonableness of the Company’s determined fair values of its reporting units, the Company evaluates its results against its current market capitalization. 

In addition, the Company would evaluate a reporting unit for impairment if events or circumstances change between annual tests indicating a possible impairment.  Examples of such events or circumstances include the following: 

· a significant adverse change in legal factors or in the business climate; 

· an adverse action or assessment by a regulator; 

· a more likely than not expectation that a segment or a significant portion thereof will be sold; or 

· the testing for recoverability of a significant asset group within the segment. 

As a result of performing the tests for potential impairment of goodwill and indefinite-lived intangible assets, the Company determined that no impairment existed as of December 31, 2013 or 2012, and, therefore, there were no write-downs to any of its goodwill or indefinite-lived intangible assets.

Impairments of Property, Plant and Equipment and Finite-Lived Intangible Assets 

Property, plant, equipment and finite-lived intangible assets are carried on the Company’s consolidated financial statements based on their cost less accumulated depreciation or amortization.  Finite-lived intangible assets consist of long-term franchise agreements, contracts, customer lists, permits and non-competition agreements.  The recoverability of these assets is tested whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. 

Typical indicators that an asset may be impaired include: 

· a significant adverse change in legal factors or in the business climate; 

· an adverse action or assessment by a regulator; 

· a more likely than not expectation that a segment or a significant portion thereof will be sold; or 

· the testing for recoverability of a significant asset group within a segment. 

If any of these or other indicators occur, a test of recoverability is performed by comparing the carrying value of the asset or asset group to its undiscounted expected future cash flows.  If the carrying value is in excess of the undiscounted expected future cash flows, impairment is measured by comparing the fair value of the asset to its carrying value.  Fair value is determined by an internally developed discounted projected cash flow analysis of the asset.  Cash flow projections are sometimes based on a group of assets, rather than a single asset.  If cash flows cannot be separately and independently identified for a single asset, the Company will determine whether an impairment has occurred for the group of assets for which the projected cash flows can be identified.  If the fair value of an asset is determined to be less than the carrying amount of the asset or asset group, an impairment in the amount of the difference is recorded in the period that the impairment indicator occurs.  Several impairment indicators are beyond the Company’s control, and whether or not they will occur cannot be predicted with any certainty.  Estimating future cash flows requires significant judgment and projections may vary from cash flows eventually realized.  There are other considerations for impairments of landfills, as described below. 

Landfills – There are certain indicators listed above that require significant judgment and understanding of the waste industry when applied to landfill development or expansion projects.  A regulator or court may deny or overturn a landfill development or landfill expansion permit application before the development or expansion permit is ultimately granted.  For example, see Note 11 for discussion of the Chaparral, New Mexico Landfill Permit Litigation, the Harper County, Kansas Landfill Permit Litigation and the Solano County, California Measure E/Landfill Expansion Litigation.  Management may periodically divert waste from one landfill to another to conserve remaining permitted landfill airspace.  Therefore, certain events could occur in the ordinary course of business and not necessarily be considered indicators of impairment due to the unique nature of the waste industry. 

Restricted Assets 

Restricted assets held by trustees consist principally of funds deposited in connection with landfill final capping, closure and post-closure obligations and other financial assurance requirements.  Proceeds from these financing arrangements are directly deposited into trust funds, and the Company does not have the ability to utilize the funds in regular operating activities.  See Note 8 for further information on restricted assets.

Fair Value of Financial Instruments 

The Company’s financial instruments consist primarily of cash and equivalents, trade receivables, restricted assets, trade payables, debt instruments, contingent consideration obligations, interest rate swaps and a fuel hedge.  As of December 31, 2013 and 2012, the carrying values of cash and equivalents, trade receivables, restricted assets, trade payables and contingent consideration are considered to be representative of their respective fair values.  The carrying values of the Company’s debt instruments, excluding certain notes as listed in the table below, approximate their fair values as of December 31, 2013 and 2012, based on current borrowing rates, current remaining average life to maturity and borrower credit quality for similar types of borrowing arrangements, and are classified as Level 2 within the fair value hierarchy.  The carrying values and fair values of the Company’s debt instruments where the carrying values do not approximate their fair values as of December 31, 2013 and 2012, are as follows: 

	Carrying Value at December 31,				Fair Value* at December 31,
	2013		2012		2013		2012
6.22% Senior Notes due 2015	$	175,000	$	175,000	$	187,206	$	193,949
3.30% Senior Notes due 2016	$	100,000	$	100,000	$	102,066	$	103,068
4.00% Senior Notes due 2018	$	50,000	$	50,000	$	50,992	$	52,476
5.25% Senior Notes due 2019	$	175,000	$	175,000	$	185,037	$	195,584
4.64% Senior Notes due 2021	$	100,000	$	100,000	$	100,341	$	107,418

______________________

*Senior Notes are classified as Level 2 within the fair value hierarchy.  Fair value is based on quotes of bonds with similar ratings in similar industries.

For details on the fair value of the Company’s interest rate swaps, fuel hedge and restricted assets, refer to Note 8. 

Derivative Financial Instruments

The Company recognizes all derivatives on the balance sheet at fair value.  All of the Company’s derivatives have been designated as cash flow hedges; therefore, the effective portion of the changes in the fair value of derivatives will be recognized in accumulated other comprehensive loss (“AOCL”) until the hedged item is recognized in earnings.  The ineffective portion of the changes in the fair value of derivatives will be immediately recognized in earnings.  The Company classifies cash inflows and outflows from derivatives within operating activities on the statement of cash flows. 

One of the Company’s objectives for utilizing derivative instruments is to reduce its exposure to fluctuations in cash flows due to changes in the variable interest rates of certain borrowings issued under its revolving credit facility.  The Company’s strategy to achieve that objective involves entering into interest rate swaps that are specifically designated to the Company’s revolving credit facility and accounted for as cash flow hedges. 

At December 31, 2013, the Company’s derivative instruments included three interest rate swap agreements as follows: 

Date Entered	Notional Amount		Fixed Interest Rate Paid*	Variable Interest Rate Received	Effective Date	Expiration Date
March 2009	$	175,000	2.85%	1-month LIBOR	February 2011	February 2014
August 2011	$	150,000	0.80%	1-month LIBOR	April 2012	January 2015
December 2011	$	175,000	1.60%	1-month LIBOR	February 2014	February 2017

____________________

*  plus applicable margin. 

Another of the Company’s objectives for utilizing derivative instruments is to reduce its exposure to fluctuations in cash flows due to changes in the price of diesel fuel.  The Company’s strategy to achieve that objective involves periodically entering into fuel hedges that are specifically designated to certain forecasted diesel fuel purchases and accounted for as cash flow hedges. 

At December 31, 2013, the Company’s derivative instruments included one fuel hedge agreement as follows: 

Date Entered	Notional Amount (in gallons per month)		Diesel Rate Paid Fixed (per gallon)	Diesel Rate Received Variable	Effective Date	Expiration Date
June 2012	300,000	$	3.60	DOE Diesel Fuel Index*	January 2014	December 2015

____________________

*  If the national U.S. on-highway average price for a gallon of diesel fuel (“average price”), as published by the Department of Energy, exceeds the contract price per gallon, the Company receives the difference between the average price and the contract price (multiplied by the notional number of gallons) from the counterparty.  If the average price is less than the contract price per gallon, the Company pays the difference to the counterparty. 

The fair values of derivative instruments designated as cash flow hedges as of December 31, 2013, were as follows: 

Derivatives Designated as Cash	Asset Derivatives			Liability Derivatives
Flow Hedges	Balance Sheet Location		Fair Value	Balance Sheet Location		Fair Value
Interest rate swaps				Accrued liabilities(a)	$	(3,373)
				Other long-term liabilities		(1,853)
Fuel hedge	Prepaid expenses and other current assets(b)	$	1,304
	Other assets, net		895
Total derivatives designated as cash flow hedges		$	2,199		$	(5,226)

(b)Represents the estimated amount of the existing unrealized gains on the fuel hedge as of December 31, 2013 (based on the forward DOE diesel fuel index curve at that date), included in AOCL expected to be reclassified into pre-tax earnings within the next 12 months.  The actual amounts reclassified into earnings are dependent on future movements in diesel fuel prices.

The fair values of derivative instruments designated as cash flow hedges as of December 31, 2012, were as follows: 

Derivatives Designated as Cash	Asset Derivatives			Liability Derivatives
Flow Hedges	Balance Sheet Location		Fair Value	Balance Sheet Location		Fair Value
Interest rate swaps				Accrued liabilities	$	(5,374)
				Other long-term liabilities		(5,789)

The following table summarizes the impact of the Company’s cash flow hedges on the results of operations, comprehensive income and AOCL for the years ended December 31, 2013, 2012 and 2011: 

Derivatives Designated as Cash Flow Hedges	Amount of Gain or (Loss) Recognized as AOCL on Derivatives, Net of Tax (Effective Portion)(a)						Statement of Income Classification	Amount of (Gain) or Loss Reclassified from AOCL into Earnings, Net of Tax (Effective Portion)(b), (c)

____________________

(a)In accordance with the derivatives and hedging guidance, the effective portions of the changes in fair values of interest rate swaps and the fuel hedge have been recorded in equity as a component of AOCL.  As the critical terms of the interest rate swaps match the underlying debt being hedged, no ineffectiveness is recognized on these swaps and, therefore, all unrealized changes in fair value are recorded in AOCL.  Because changes in the actual price of diesel fuel and changes in the DOE index price do not offset exactly each reporting period, the Company assesses whether the fuel hedge is highly effective using the cumulative dollar offset approach. 

(b)Amounts reclassified from AOCL into earnings related to realized gains and losses on interest rate swaps are recognized when interest payments or receipts occur related to the swap contracts, which correspond to when interest payments are made on the Company’s hedged debt. 

(c)Amounts reclassified from AOCL into earnings related to realized gains and losses on the fuel hedge are recognized when settlement payments or receipts occur related to the hedge contract, which correspond to when the underlying fuel is consumed. 

The Company measures and records ineffectiveness on the fuel hedge in Cost of operations in the Consolidated Statements of Net Income on a monthly basis based on the difference between the DOE index price and the actual price of diesel fuel purchased, multiplied by the notional number of gallons on the contracts.  There was no significant ineffectiveness recognized on the fuel hedges during the years ended December 31, 2013, 2012 and 2011. 

See Note 13 for further discussion on the impact of the Company’s hedge accounting to its consolidated Comprehensive income and AOCL. 

Income Taxes  

Deferred tax assets and liabilities are determined based on differences between the financial reporting and income tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse.  The Company records valuation allowances to reduce net deferred tax assets to the amount considered more likely than not to be realized.

The Company is required to evaluate whether the tax positions taken on its federal and state income tax returns will more likely than not be sustained upon examination by the appropriate taxing authority.  If the Company determines that such tax positions will not be sustained, it records a liability for the related unrecognized tax benefits.  The Company classifies its liability for unrecognized tax benefits as a current liability to the extent it anticipates making a payment within one year. 

Equity-Based Compensation 

The fair value of restricted stock units is determined based on the number of shares granted and the closing price of the Company’s common stock. 

All share-based compensation cost is measured at the grant date, based on the estimated fair value of the award, and is recognized on a straight-line basis as expense over the employee’s requisite service period.  The Company calculates potential income tax windfalls and shortfalls under the treasury stock method by including the impact of pro forma deferred tax assets in the calculation of diluted earnings per common share.  Under the stock-based compensation guidance, the Company elected to use the short-cut method to calculate the historical pool of windfall tax benefits.  The Company elected to use the tax law ordering approach for purposes of determining whether an excess of tax benefit has been realized. 

Warrants are valued using the Black-Scholes pricing model with a contractual life of five years, a risk free interest rate based on the 5-year U.S. treasury yield curve and expected volatility.  The Company uses the historical volatility of its common stock over a period equivalent to the contractual life of the warrants to estimate the expected volatility.  Warrants issued to consultants are recorded as an element of the related cost of landfill development projects or to expense for warrants issued in connection with acquisitions. 

Equity-based compensation expense recognized during the years ended December 31, 2013, 2012 and 2011, was approximately $15,397($9,508net of taxes), $17,289($11,803 net of taxes) and $11,879($7,365 net of taxes), respectively, and consisted of restricted stock unit and warrant expense.  The Company records equity-based compensation expense in Selling, general and administrative expenses in the Consolidated Statements of Net Income.  The total unrecognized compensation cost at December 31, 2013, related to unvested restricted stock unit awards was $25,138and that future expense will be recognized over the remaining vesting period of the restricted stock unit awards, which extends to 2017.  The weighted average remaining vesting period of those awards is 1.1years. 

Per Share Information 

Basic net income per share attributable to Waste Connections’ common stockholders is computed using the weighted average number of common shares outstanding and vested and unissued restricted stock units deferred for issuance into the deferred compensation plan.  Diluted net income per share attributable to Waste Connections’ common stockholders is computed using the weighted average number of common and potential common shares outstanding.  Potential common shares are excluded from the computation if their effect is anti-dilutive. 

Advertising Costs 

Advertising costs are expensed as incurred.  Advertising expense for the years ended December 31, 2013, 2012 and 2011, was $3,704,  $3,737 and $3,679, respectively, which is included in Selling, general and administrative expense in the Consolidated Statements of Net Income. 

Insurance Liabilities 

As a result of its high deductible or self-insured retention insurance policies, the Company is effectively self-insured for automobile liability, general liability, employer’s liability, environmental liability, cyber liability, employment practices liability, directors’ and officers’ liability as well as for employee group health insurance, property and workers’ compensation.  The Company’s insurance accruals are based on claims filed and estimates of claims incurred but not reported and are developed by the Company’s management with assistance from its third-party actuary and its third-party claims administrator.  The insurance accruals are influenced by the Company’s past claims experience factors, which have a limited history, and by published industry development factors.  At December 31, 2013 and 2012, the Company’s total accrual for self-insured liabilities was $42,732 and $43,935, respectively, which is included in Accrued liabilities in the Consolidated Balance Sheets.

Organization, Business and Summary of Significant Accounting Policies [Abstract]

Organization and Business

Organization and Business

Waste Connections, Inc. (“WCI” or the “Company”) was incorporated in Delaware on September 9, 1997, and commenced its operations on October 1, 1997, through the purchase of certain solid waste operations in the state of Washington.  The Company is an integrated municipal solid waste services company that provides solid waste collection, transfer, disposal and recycling services in mostly exclusive and secondary markets in the U.S. and a leading provider of non-hazardous exploration and production (“E&P”) waste treatment, recovery and disposal services in several of the most active natural resource producing areas of the U.S.  The Company also provides intermodal services for the rail haul movement of cargo and solid waste containers in the Pacific Northwest.

Basis of Presentation

Basis of Presentation 

These consolidated financial statements include the accounts of WCI and its wholly-owned and majority-owned subsidiaries.  The consolidated entity is referred to herein as the Company.  All significant intercompany accounts and transactions have been eliminated in consolidation. 

Cash Equivalents

Cash Equivalents 

The Company considers all highly liquid investments with a maturity of three months or less at purchase to be cash equivalents.  As of December 31, 2013 and 2012, cash equivalents consisted of demand money market accounts.

Concentrations of Credit Risk

Concentrations of Credit Risk 

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and equivalents, restricted assets and accounts receivable.  The Company maintains cash and 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’s restricted assets are invested primarily in U.S. government and agency securities.  The Company has not experienced any losses related to its cash and equivalents or restricted asset 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.  The Company maintains allowances for losses based on the expected collectability of accounts receivable. 

Revenue Recognition and Accounts Receivable

Revenue Recognition and Accounts Receivable 

Revenues are recognized when persuasive evidence of an arrangement exists, the service has been provided, the price is fixed or determinable and collection is reasonably assured.  Certain customers are billed in advance and, accordingly, recognition of the related revenues is deferred until the services are provided.  In accordance with revenue recognition guidance, any tax assessed by a governmental authority that is directly imposed on a revenue-producing transaction between a seller and a customer is presented in the statements of net income on a net basis (excluded from revenues). 

The Company’s receivables are recorded when billed or accrued and represent claims against third parties that will be settled in cash.  The carrying value of the Company’s receivables, net of the allowance for doubtful accounts, represents their estimated net realizable value.  The Company estimates its allowance for doubtful accounts based on historical collection trends, type of customer such as municipal or non-municipal, the age of outstanding receivables 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 and the allowance is adjusted accordingly.  Past-due receivable balances are written off when the Company’s internal collection efforts have been unsuccessful in collecting the amount due. 

Property and Equipment

Property and Equipment 

Property and equipment are stated at cost.  Improvements or betterments, not considered to be maintenance and repair, which add new functionality or significantly extend the life of an asset are capitalized.  Third-party expenditures related to pending development projects, such as legal and engineering expenses, are capitalized.  Expenditures for maintenance and repair costs, including planned major maintenance activities, are charged to expense as incurred.  The cost of assets retired or otherwise disposed of and the related accumulated depreciation are eliminated from the accounts in the year of disposal.  Gains and losses resulting from disposals of property and equipment are recognized in the period in which the property and equipment is disposed.  Depreciation is computed using the straight-line method over the estimated useful lives of the assets or the lease term, whichever is shorter. 

The estimated useful lives are as follows: 

Buildings	10 – 20 years
Leasehold and land improvements	3 – 10 years
Machinery and equipment	3 – 12 years
Rolling stock	2 – 10 years
Containers	5 – 12 years
Rail cars	20 years

Landfill Accounting

Landfill Accounting

The Company utilizes the life cycle method of accounting for landfill costs.  This method applies the costs to be capitalized associated with acquiring, developing, closing and monitoring the landfills over the associated consumption of landfill capacity.  The Company utilizes the units of consumption method to amortize landfill development costs over the estimated remaining capacity of a landfill.  Under this method, the Company includes future estimated construction costs using current dollars, as well as costs incurred to date, in the amortization base.  When certain criteria are met, the Company includes expansion airspace, which has not been permitted, in the calculation of the total remaining capacity of the landfill. 

- Landfill development costs.  Landfill development costs include the costs of acquisition, construction associated with excavation, liners, site berms, groundwater monitoring wells, gas recovery systems and leachate collection systems.  The Company estimates the total costs associated with developing each landfill site to its final capacity.  This includes certain projected landfill site costs that are uncertain because they are dependent on future events and thus actual costs could vary significantly from estimates.  The total cost to develop a site to its final capacity includes amounts previously expended and capitalized, net of accumulated depletion, and projections of future purchase and development costs, liner construction costs, and operating construction costs.  Total landfill costs include the development costs associated with expansion airspace.  Expansion airspace is addressed below. 

- Final capping, closure and post-closure obligations.  The Company accrues for estimated final capping, closure and post-closure maintenance obligations at the landfills it owns and five of the six landfills that it operates, but does not own under life-of-site agreements.  Accrued final capping, closure and post-closure costs represent an estimate of the current value of the future obligation associated with final capping, closure and post-closure monitoring of non-hazardous solid waste landfills currently owned or operated under life-of-site agreements by the Company.  Final capping costs represent the costs related to installation of clay liners, drainage and compacted soil layers and topsoil constructed over areas of the landfill where total airspace capacity has been consumed.  Closure and post-closure monitoring and maintenance costs represent the costs related to cash expenditures yet to be incurred when a landfill facility ceases to accept waste and closes.  Accruals for final capping, closure and post-closure monitoring and maintenance requirements in the U.S. consider site inspection, groundwater monitoring, leachate management, methane gas control and recovery, and operating and maintenance costs to be incurred during the period after the facility closes.  Certain of these environmental costs, principally capping and methane gas control costs, are also incurred during the operating life of the site in accordance with the landfill operation requirements of Subtitle D and the air emissions standards.  Daily maintenance activities, which include many of these costs, are expensed as incurred during the operating life of the landfill.  Daily maintenance activities include leachate disposal; surface water, groundwater, and methane gas monitoring and maintenance; other pollution control activities; mowing and fertilizing the landfill final cap; fence and road maintenance; and third-party inspection and reporting costs.  Site specific final capping, closure and post-closure engineering cost estimates are prepared annually for landfills owned or landfills operated under life-of-site agreements by the Company for which it is responsible for final capping, closure and post-closure. 

The net present value of landfill final capping, closure and post-closure liabilities are calculated by estimating the total obligation in current dollars, inflating the obligation based upon the expected date of the expenditure and discounting the inflated total to its present value using a credit-adjusted risk-free rate.  Any changes in expectations that result in an upward revision to the estimated undiscounted cash flows are treated as a new liability and are inflated and discounted at rates reflecting current market conditions.  Any changes in expectations that result in a downward revision (or no revision) to the estimated undiscounted cash flows result in a liability that is inflated and discounted at rates reflecting the market conditions at the time the cash flows were originally estimated.  This policy results in the Company’s final capping, closure and post-closure liabilities being recorded in “layers.”  The Company’s discount rate assumption for purposes of computing 2013 and 2012 “layers” for final capping, closure and post-closure obligations was 5.75% for each year, which reflects the Company’s long-term cost of borrowing as of the end of 2012 and 2011.  The Company’s inflation rate assumption was 2.5% for the years ended December 31, 2013 and 2012.  

In accordance with the accounting guidance on asset retirement obligations, the final capping, closure and post-closure liability is recorded on the balance sheet along with an offsetting addition to site costs which is amortized to depletion expense on a units-of-consumption basis as remaining landfill airspace is consumed.  The impact of changes determined to be changes in estimates, based on an annual update, is accounted for on a prospective basis.  Depletion expense resulting from final capping, closure and post-closure obligations recorded as a component of landfill site costs will generally be less during the early portion of a landfill’s operating life and increase thereafter.  Owned landfills and landfills operated under life-of-site agreements have estimated remaining lives, based on remaining permitted capacity, probable expansion capacity and projected annual disposal volumes, that range from approximately 5to 200 years, with an average remaining life of approximately 42years.  The costs for final capping, closure and post-closure obligations at landfills the Company owns or operates under life-of-site agreements are generally estimated based on interpretations of current requirements and proposed or anticipated regulatory changes. 

The estimates for landfill final capping, closure and post-closure costs consider when the costs would actually be paid and factor in inflation and discount rates.  Interest is accreted on the recorded liability using the corresponding discount rate.  When using discounted cash flow techniques, reliable estimates of market premiums may not be obtainable.  In the waste industry, there is no market for selling the responsibility for final capping, closure and post-closure obligations independent of selling the landfill in its entirety.  Accordingly, the Company does not believe that it is possible to develop a methodology to reliably estimate a market risk premium and has therefore excluded any such market risk premium from its determination of expected cash flows for landfill asset retirement obligations.  The possibility of changing legal and regulatory requirements and the forward-looking nature of these types of costs make any estimation or assumption less certain. 

The following is a reconciliation of the Company’s final capping, closure and post-closure liability balance from December 31, 2011 to December 31, 2013: 

Final capping, closure and post-closure liability at December 31, 2011	$	30,883
Adjustments to final capping, closure and post-closure liabilities		3,535
Liabilities incurred		2,926
Accretion expense associated with landfill obligations		2,581
Closure payments		(22)
Assumption of closure liabilities from acquisitions		6,570
Final capping, closure and post-closure liability at December 31, 2012		46,473
Adjustments to final capping, closure and post-closure liabilities		(3,528)
Liabilities incurred		4,668
Accretion expense associated with landfill obligations		2,749
Closure payments		(234)
Final capping, closure and post-closure liability at December 31, 2013	$	50,128

The Adjustments to final capping, closure and post-closure liabilities for the year ended December 31, 2013, primarily consisted of increases in estimated airspace at some of the Company’s landfills at which expansions are being pursued or have been granted, decreases in estimated closure costs at some of the Company’s landfills and revisions in engineering estimates, partially offset by an increase in estimates of annual tonnage consumption at some of the Company’s landfills.  The Adjustments to final capping, closure and post-closure liabilities for the year ended December 31, 2012, primarily consisted of increases in estimated closure costs and changes in timing of closure activities at some of the Company’s landfills, partially offset by a decrease in closure liabilities from third parties due to changes in timing of closure activities and reduced closure expenses.  The final capping, closure and post-closure liability is included in Other long-term liabilities in the Consolidated Balance Sheets.  The Company performs its annual review of its cost and capacity estimates in the first quarter of each year. 

At December 31, 2013, $33,466 of the Company’s restricted assets balance was for purposes of securing its performance of future final capping, closure and post-closure obligations. 

- Disposal capacity.  The Company’s internal and third-party engineers perform surveys at least annually to estimate the remaining disposal capacity at its landfills.  This is done by using surveys and other methods to calculate, based on the terms of the permit, height restrictions and other factors, how much airspace is left to fill and how much waste can be disposed of at a landfill before it has reached its final capacity.  The Company’s landfill depletion rates are based on the remaining disposal capacity, considering both permitted and probable expansion airspace, at the landfills it owns, and certain landfills it operates, but does not own, under life-of-site agreements.  The Company’s landfill depletion rate is based on the term of the operating agreement at its operated landfill that has capitalized expenditures.  Expansion airspace consists of additional disposal capacity being pursued through means of an expansion that has not yet been permitted.  Expansion airspace that meets the following criteria is included in the estimate of total landfill airspace: 

1) whether the land where the expansion is being sought is contiguous to the current disposal site, and the Company either owns the expansion property or has rights to it under an option, purchase, operating or other similar agreement; 

2) whether total development costs, final capping costs, and closure/post-closure costs have been determined; 

3) whether internal personnel have performed a financial analysis of the proposed expansion site and have determined that it has a positive financial and operational impact; 

4) whether internal personnel or external consultants are actively working to obtain the necessary approvals to obtain the landfill expansion permit; and 

5) whether the Company considers it probable that the Company will achieve the expansion (for a pursued expansion to be considered probable, there must be no significant known technical, legal, community, business, or political restrictions or similar issues existing that the Company believes are more likely than not to impair the success of the expansion). 

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, as described below, 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 Company periodically evaluates its landfill sites for potential impairment indicators.  The Company’s judgments regarding the existence of impairment indicators are based on regulatory factors, market conditions and operational performance of its landfills.  Future events could cause the Company to conclude that impairment indicators exist and that its landfill carrying costs are impaired. 

Cell Processing Reserves

Cell Processing Reserves

The Company records a cell processing reserve related to its E&P segment for certain locations in Louisiana and Texas for the estimated amount of expenses to be incurred upon the treatment and excavation of oilfield waste received.  The cell processing reserve is the future cost to properly treat and dispose of existing waste within the cells at the various facilities.  The reserve generally covers estimated costs to be incurred over a period of time up to 24 months, with the current portion representing costs estimated to be incurred in the next 12 months.  The estimate is calculated based on current estimated volume in the cells, estimated percentage of waste treated, and historical average costs to treat and excavate the waste.  The processing reserve represents the estimated costs to process the volumes of oilfield waste on-hand for which revenue has been recognized.  At December 31, 2013 and 2012, the current portion of cell processing reserves was $7,013 and $6,442, respectively, which is included in Accrued liabilities in the Consolidated Balance Sheets. At December 31, 2013 and 2012, the long-term portion of cell processing reserves was $2,416 and $2,043, respectively, which is included in Other long-term liabilities in the Consolidated Balance Sheets.

Business Combination Accounting

Business Combination Accounting

The Company accounts for business combinations as follows: 

· The Company recognizes, separately from goodwill, the identifiable assets acquired and liabilities assumed at their estimated acquisition date fair values.  The Company measures and recognizes goodwill as of the acquisition date as the excess of:  (a) the aggregate of the fair value of consideration transferred, the fair value of any noncontrolling interest in the acquiree (if any) and the acquisition date fair value of the Company’s previously held equity interest in the acquiree (if any), over (b) the fair value of net assets acquired and liabilities assumed. 

· At the acquisition date, the Company measures the fair values of all assets acquired and liabilities assumed that arise from contractual contingencies.  The Company measures the fair values of all noncontractual contingencies if, as of the acquisition date, it is more likely than not that the contingency will give rise to an asset or liability. 

Finite-Lived Intangible Assets

Finite-Lived Intangible Assets

The amounts assigned to franchise agreements, contracts and customer listsare being amortized on a straight-line basis over the expected term of the related agreements (ranging from 1 to 56 years). 

Goodwill and Indefinite-Lived Intangible Assets

Goodwill and Indefinite-Lived Intangible Assets 

The Company acquired indefinite-lived intangible assets in connection with certain of its acquisitions.  The amounts assigned to indefinite-lived intangible assets consist of the value of certain perpetual rights to provide solid waste collection and transportation services in specified territories and to operate exploration and production waste treatment and disposal facilities.  The Company measures and recognizes acquired indefinite-lived intangible assets at their estimated acquisition date fair values.  Indefinite-lived intangible assets are not amortized.  Goodwill represents the excess of:  (a) the aggregate of the fair value of consideration transferred, the fair value of any noncontrolling interest in the acquiree (if any) and the acquisition date fair value of the Company’s previously held equity interest in the acquiree (if any), over (b)  the fair value of assets acquired and liabilities assumed.  Goodwill and intangible assets, deemed to have indefinite lives, are subject to annual impairment tests as described below. 

Goodwill and indefinite-lived intangible assets are tested for impairment on at least an annual basis in the fourth quarter of the year. In the first step of testing for goodwill impairment, the Company estimates the fair value of each reporting unit, which the Company has determined to be its three geographic operating segments and its E&P segment, and compares the fair value with the carrying value of the net assets assigned to each reporting unit.  If the fair value of a reporting unit is greater than the carrying value of the net assets, including goodwill, assigned to the reporting unit, then no impairment results.  If the fair value is less than the carrying value, then the Company would perform a second step and determine the fair value of the goodwill.  In this second step, the fair value of goodwill is determined by deducting the fair value of a reporting unit’s identifiable assets and liabilities from the fair value of the reporting unit as a whole, as if that reporting unit had just been acquired and the purchase price were being initially allocated.  If the fair value of the goodwill is less than its carrying value for a reporting unit, an impairment charge would be recorded to earnings in the Company’s Consolidated Statements of Net Income.  In testing indefinite-lived intangible assets for impairment, the Company compares the estimated fair value of each indefinite-lived intangible asset to its carrying value.  If the fair value of the indefinite-lived intangible asset is less than its carrying value, an impairment charge would be recorded to earnings in the Company’s Consolidated Statements of Net Income. 

To determine the fair value of each of the Company’s reporting units as a whole and each indefinite-lived intangible asset, the Company uses discounted cash flow analyses, which require significant assumptions and estimates about the future operations of each reporting unit and the future discrete cash flows related to each indefinite-lived intangible asset.  Significant judgments inherent in these analyses include the determination of appropriate discount rates, the amount and timing of expected future cash flows and growth rates.  The cash flows employed in the Company’s 2013 discounted cash flow analyses were based on ten-year financial forecasts, which in turn were based on the 2014 annual budget developed internally by management.  These forecasts reflect operating profit margins that were consistent with 2013 results and perpetual revenue growth rates of 3.2%.  The Company’s discount rate assumptions are based on an assessment of the Company’s weighted average cost of capital which approximated 5.4%.  In assessing the reasonableness of the Company’s determined fair values of its reporting units, the Company evaluates its results against its current market capitalization. 

In addition, the Company would evaluate a reporting unit for impairment if events or circumstances change between annual tests indicating a possible impairment.  Examples of such events or circumstances include the following: 

· a significant adverse change in legal factors or in the business climate; 

· an adverse action or assessment by a regulator; 

· a more likely than not expectation that a segment or a significant portion thereof will be sold; or 

· the testing for recoverability of a significant asset group within the segment. 

As a result of performing the tests for potential impairment of goodwill and indefinite-lived intangible assets, the Company determined that no impairment existed as of December 31, 2013 or 2012, and, therefore, there were no write-downs to any of its goodwill or indefinite-lived intangible assets.

Impairments of Property, Plant and Equipment and Finite-Lived Intangible Assets

Impairments of Property, Plant and Equipment and Finite-Lived Intangible Assets 

Property, plant, equipment and finite-lived intangible assets are carried on the Company’s consolidated financial statements based on their cost less accumulated depreciation or amortization.  Finite-lived intangible assets consist of long-term franchise agreements, contracts, customer lists, permits and non-competition agreements.  The recoverability of these assets is tested whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. 

Typical indicators that an asset may be impaired include: 

· a significant adverse change in legal factors or in the business climate; 

· an adverse action or assessment by a regulator; 

· a more likely than not expectation that a segment or a significant portion thereof will be sold; or 

· the testing for recoverability of a significant asset group within a segment. 

If any of these or other indicators occur, a test of recoverability is performed by comparing the carrying value of the asset or asset group to its undiscounted expected future cash flows.  If the carrying value is in excess of the undiscounted expected future cash flows, impairment is measured by comparing the fair value of the asset to its carrying value.  Fair value is determined by an internally developed discounted projected cash flow analysis of the asset.  Cash flow projections are sometimes based on a group of assets, rather than a single asset.  If cash flows cannot be separately and independently identified for a single asset, the Company will determine whether an impairment has occurred for the group of assets for which the projected cash flows can be identified.  If the fair value of an asset is determined to be less than the carrying amount of the asset or asset group, an impairment in the amount of the difference is recorded in the period that the impairment indicator occurs.  Several impairment indicators are beyond the Company’s control, and whether or not they will occur cannot be predicted with any certainty.  Estimating future cash flows requires significant judgment and projections may vary from cash flows eventually realized.  There are other considerations for impairments of landfills, as described below. 

Landfills – There are certain indicators listed above that require significant judgment and understanding of the waste industry when applied to landfill development or expansion projects.  A regulator or court may deny or overturn a landfill development or landfill expansion permit application before the development or expansion permit is ultimately granted.  For example, see Note 11 for discussion of the Chaparral, New Mexico Landfill Permit Litigation, the Harper County, Kansas Landfill Permit Litigation and the Solano County, California Measure E/Landfill Expansion Litigation.  Management may periodically divert waste from one landfill to another to conserve remaining permitted landfill airspace.  Therefore, certain events could occur in the ordinary course of business and not necessarily be considered indicators of impairment due to the unique nature of the waste industry. 

Restricted Assets

Restricted Assets 

Restricted assets held by trustees consist principally of funds deposited in connection with landfill final capping, closure and post-closure obligations and other financial assurance requirements.  Proceeds from these financing arrangements are directly deposited into trust funds, and the Company does not have the ability to utilize the funds in regular operating activities.  See Note 8 for further information on restricted assets.

Fair Value of Financial Instruments

Fair Value of Financial Instruments 

The Company’s financial instruments consist primarily of cash and equivalents, trade receivables, restricted assets, trade payables, debt instruments, contingent consideration obligations, interest rate swaps and a fuel hedge.  As of December 31, 2013 and 2012, the carrying values of cash and equivalents, trade receivables, restricted assets, trade payables and contingent consideration are considered to be representative of their respective fair values.  The carrying values of the Company’s debt instruments, excluding certain notes as listed in the table below, approximate their fair values as of December 31, 2013 and 2012, based on current borrowing rates, current remaining average life to maturity and borrower credit quality for similar types of borrowing arrangements, and are classified as Level 2 within the fair value hierarchy.  The carrying values and fair values of the Company’s debt instruments where the carrying values do not approximate their fair values as of December 31, 2013 and 2012, are as follows: 

	Carrying Value at December 31,				Fair Value* at December 31,
	2013		2012		2013		2012
6.22% Senior Notes due 2015	$	175,000	$	175,000	$	187,206	$	193,949
3.30% Senior Notes due 2016	$	100,000	$	100,000	$	102,066	$	103,068
4.00% Senior Notes due 2018	$	50,000	$	50,000	$	50,992	$	52,476
5.25% Senior Notes due 2019	$	175,000	$	175,000	$	185,037	$	195,584
4.64% Senior Notes due 2021	$	100,000	$	100,000	$	100,341	$	107,418

______________________

*Senior Notes are classified as Level 2 within the fair value hierarchy.  Fair value is based on quotes of bonds with similar ratings in similar industries.

For details on the fair value of the Company’s interest rate swaps, fuel hedge and restricted assets, refer to Note 8. 

Derivative Financial Instruments

Derivative Financial Instruments

The Company recognizes all derivatives on the balance sheet at fair value.  All of the Company’s derivatives have been designated as cash flow hedges; therefore, the effective portion of the changes in the fair value of derivatives will be recognized in accumulated other comprehensive loss (“AOCL”) until the hedged item is recognized in earnings.  The ineffective portion of the changes in the fair value of derivatives will be immediately recognized in earnings.  The Company classifies cash inflows and outflows from derivatives within operating activities on the statement of cash flows. 

One of the Company’s objectives for utilizing derivative instruments is to reduce its exposure to fluctuations in cash flows due to changes in the variable interest rates of certain borrowings issued under its revolving credit facility.  The Company’s strategy to achieve that objective involves entering into interest rate swaps that are specifically designated to the Company’s revolving credit facility and accounted for as cash flow hedges. 

At December 31, 2013, the Company’s derivative instruments included three interest rate swap agreements as follows: 

Date Entered	Notional Amount		Fixed Interest Rate Paid*	Variable Interest Rate Received	Effective Date	Expiration Date
March 2009	$	175,000	2.85%	1-month LIBOR	February 2011	February 2014
August 2011	$	150,000	0.80%	1-month LIBOR	April 2012	January 2015
December 2011	$	175,000	1.60%	1-month LIBOR	February 2014	February 2017

____________________

*  plus applicable margin. 

Another of the Company’s objectives for utilizing derivative instruments is to reduce its exposure to fluctuations in cash flows due to changes in the price of diesel fuel.  The Company’s strategy to achieve that objective involves periodically entering into fuel hedges that are specifically designated to certain forecasted diesel fuel purchases and accounted for as cash flow hedges. 

At December 31, 2013, the Company’s derivative instruments included one fuel hedge agreement as follows: 

Date Entered	Notional Amount (in gallons per month)		Diesel Rate Paid Fixed (per gallon)	Diesel Rate Received Variable	Effective Date	Expiration Date
June 2012	300,000	$	3.60	DOE Diesel Fuel Index*	January 2014	December 2015

____________________

*  If the national U.S. on-highway average price for a gallon of diesel fuel (“average price”), as published by the Department of Energy, exceeds the contract price per gallon, the Company receives the difference between the average price and the contract price (multiplied by the notional number of gallons) from the counterparty.  If the average price is less than the contract price per gallon, the Company pays the difference to the counterparty. 

The fair values of derivative instruments designated as cash flow hedges as of December 31, 2013, were as follows: 

Derivatives Designated as Cash	Asset Derivatives			Liability Derivatives
Flow Hedges	Balance Sheet Location		Fair Value	Balance Sheet Location		Fair Value
Interest rate swaps				Accrued liabilities(a)	$	(3,373)
				Other long-term liabilities		(1,853)
Fuel hedge	Prepaid expenses and other current assets(b)	$	1,304
	Other assets, net		895
Total derivatives designated as cash flow hedges		$	2,199		$	(5,226)

(a)Represents the estimated amount of the existing unrealized losses on interest rate swaps as of December 31, 2013 (based on the interest rate yield curve at that date), included in AOCL expected to be reclassified into pre-tax earnings within the next 12 months.  The actual amounts reclassified into earnings are dependent on future movements in interest rates.

(b)Represents the estimated amount of the existing unrealized gains on the fuel hedge as of December 31, 2013 (based on the forward DOE diesel fuel index curve at that date), included in AOCL expected to be reclassified into pre-tax earnings within the next 12 months.  The actual amounts reclassified into earnings are dependent on future movements in diesel fuel prices.

The fair values of derivative instruments designated as cash flow hedges as of December 31, 2012, were as follows: 

Derivatives Designated as Cash	Asset Derivatives			Liability Derivatives
Flow Hedges	Balance Sheet Location		Fair Value	Balance Sheet Location		Fair Value
Interest rate swaps				Accrued liabilities	$	(5,374)
				Other long-term liabilities		(5,789)

Total derivatives designated as cash flow hedges		$	1,187		$	(11,163)

The following table summarizes the impact of the Company’s cash flow hedges on the results of operations, comprehensive income and AOCL for the years ended December 31, 2013, 2012 and 2011: 

Derivatives Designated as Cash Flow Hedges	Amount of Gain or (Loss) Recognized as AOCL on Derivatives, Net of Tax (Effective Portion)(a)						Statement of Income Classification	Amount of (Gain) or Loss Reclassified from AOCL into Earnings, Net of Tax (Effective Portion)(b), (c)

____________________

(a)In accordance with the derivatives and hedging guidance, the effective portions of the changes in fair values of interest rate swaps and the fuel hedge have been recorded in equity as a component of AOCL.  As the critical terms of the interest rate swaps match the underlying debt being hedged, no ineffectiveness is recognized on these swaps and, therefore, all unrealized changes in fair value are recorded in AOCL.  Because changes in the actual price of diesel fuel and changes in the DOE index price do not offset exactly each reporting period, the Company assesses whether the fuel hedge is highly effective using the cumulative dollar offset approach. 

(b)Amounts reclassified from AOCL into earnings related to realized gains and losses on interest rate swaps are recognized when interest payments or receipts occur related to the swap contracts, which correspond to when interest payments are made on the Company’s hedged debt. 

(c)Amounts reclassified from AOCL into earnings related to realized gains and losses on the fuel hedge are recognized when settlement payments or receipts occur related to the hedge contract, which correspond to when the underlying fuel is consumed. 

The Company measures and records ineffectiveness on the fuel hedge in Cost of operations in the Consolidated Statements of Net Income on a monthly basis based on the difference between the DOE index price and the actual price of diesel fuel purchased, multiplied by the notional number of gallons on the contracts.  There was no significant ineffectiveness recognized on the fuel hedges during the years ended December 31, 2013, 2012 and 2011. 

See Note 13 for further discussion on the impact of the Company’s hedge accounting to its consolidated Comprehensive income and AOCL. 

Income Taxes

Income Taxes  

Deferred tax assets and liabilities are determined based on differences between the financial reporting and income tax bases of assets and liabilities and are measured using the enacted tax rates and laws that are expected to be in effect when the differences are expected to reverse.  The Company records valuation allowances to reduce net deferred tax assets to the amount considered more likely than not to be realized.

The Company is required to evaluate whether the tax positions taken on its federal and state income tax returns will more likely than not be sustained upon examination by the appropriate taxing authority.  If the Company determines that such tax positions will not be sustained, it records a liability for the related unrecognized tax benefits.  The Company classifies its liability for unrecognized tax benefits as a current liability to the extent it anticipates making a payment within one year. 

Equity-Based Compensation

Equity-Based Compensation 

The fair value of restricted stock units is determined based on the number of shares granted and the closing price of the Company’s common stock. 

All share-based compensation cost is measured at the grant date, based on the estimated fair value of the award, and is recognized on a straight-line basis as expense over the employee’s requisite service period.  The Company calculates potential income tax windfalls and shortfalls under the treasury stock method by including the impact of pro forma deferred tax assets in the calculation of diluted earnings per common share.  Under the stock-based compensation guidance, the Company elected to use the short-cut method to calculate the historical pool of windfall tax benefits.  The Company elected to use the tax law ordering approach for purposes of determining whether an excess of tax benefit has been realized. 

Warrants are valued using the Black-Scholes pricing model with a contractual life of five years, a risk free interest rate based on the 5-year U.S. treasury yield curve and expected volatility.  The Company uses the historical volatility of its common stock over a period equivalent to the contractual life of the warrants to estimate the expected volatility.  Warrants issued to consultants are recorded as an element of the related cost of landfill development projects or to expense for warrants issued in connection with acquisitions. 

Equity-based compensation expense recognized during the years ended December 31, 2013, 2012 and 2011, was approximately $15,397($9,508net of taxes), $17,289($11,803 net of taxes) and $11,879($7,365 net of taxes), respectively, and consisted of restricted stock unit and warrant expense.  The Company records equity-based compensation expense in Selling, general and administrative expenses in the Consolidated Statements of Net Income.  The total unrecognized compensation cost at December 31, 2013, related to unvested restricted stock unit awards was $25,138and that future expense will be recognized over the remaining vesting period of the restricted stock unit awards, which extends to 2017.  The weighted average remaining vesting period of those awards is 1.1years. 

Per Share Information

Per Share Information 

Basic net income per share attributable to Waste Connections’ common stockholders is computed using the weighted average number of common shares outstanding and vested and unissued restricted stock units deferred for issuance into the deferred compensation plan.  Diluted net income per share attributable to Waste Connections’ common stockholders is computed using the weighted average number of common and potential common shares outstanding.  Potential common shares are excluded from the computation if their effect is anti-dilutive. 

Advertising Costs

Advertising Costs 

Advertising costs are expensed as incurred.  Advertising expense for the years ended December 31, 2013, 2012 and 2011, was $3,704,  $3,737 and $3,679, respectively, which is included in Selling, general and administrative expense in the Consolidated Statements of Net Income. 

Insurance Liabilities

Insurance Liabilities 

As a result of its high deductible or self-insured retention insurance policies, the Company is effectively self-insured for automobile liability, general liability, employer’s liability, environmental liability, cyber liability, employment practices liability, directors’ and officers’ liability as well as for employee group health insurance, property and workers’ compensation.  The Company’s insurance accruals are based on claims filed and estimates of claims incurred but not reported and are developed by the Company’s management with assistance from its third-party actuary and its third-party claims administrator.  The insurance accruals are influenced by the Company’s past claims experience factors, which have a limited history, and by published industry development factors.  At December 31, 2013 and 2012, the Company’s total accrual for self-insured liabilities was $42,732 and $43,935, respectively, which is included in Accrued liabilities in the Consolidated Balance Sheets.

(a)Represents the estimated amount of the existing unrealized losses on interest rate swaps as of December 31, 2013 (based on the interest rate yield curve at that date), included in AOCL expected to be reclassified into pre-tax earnings within the next 12 months.  The actual amounts reclassified into earnings are dependent on future movements in interest rates.

(b)Represents the estimated amount of the existing unrealized gains on the fuel hedge as of December 31, 2013 (based on the forward DOE diesel fuel index curve at that date), included in AOCL expected to be reclassified into pre-tax earnings within the next 12 months.  The actual amounts reclassified into earnings are dependent on future movements in diesel fuel prices.

____________________

(a)In accordance with the derivatives and hedging guidance, the effective portions of the changes in fair values of interest rate swaps and the fuel hedge have been recorded in equity as a component of AOCL.  As the critical terms of the interest rate swaps match the underlying debt being hedged, no ineffectiveness is recognized on these swaps and, therefore, all unrealized changes in fair value are recorded in AOCL.  Because changes in the actual price of diesel fuel and changes in the DOE index price do not offset exactly each reporting period, the Company assesses whether the fuel hedge is highly effective using the cumulative dollar offset approach. 

(b)Amounts reclassified from AOCL into earnings related to realized gains and losses on interest rate swaps are recognized when interest payments or receipts occur related to the swap contracts, which correspond to when interest payments are made on the Company’s hedged debt. 

(c)Amounts reclassified from AOCL into earnings related to realized gains and losses on the fuel hedge are recognized when settlement payments or receipts occur related to the hedge contract, which correspond to when the underlying fuel is consumed.

Fuel Hedge Agreements

Company's derivative instruments

At December 31, 2013, the Company’s derivative instruments included one fuel hedge agreement as follows: 

Date Entered	Notional Amount (in gallons per month)		Diesel Rate Paid Fixed (per gallon)	Diesel Rate Received Variable	Effective Date	Expiration Date
June 2012	300,000	$	3.60	DOE Diesel Fuel Index*	January 2014	December 2015

____________________

*  If the national U.S. on-highway average price for a gallon of diesel fuel (“average price”), as published by the Department of Energy, exceeds the contract price per gallon, the Company receives the difference between the average price and the contract price (multiplied by the notional number of gallons) from the counterparty.  If the average price is less than the contract price per gallon, the Company pays the difference to the counterparty.

During the years ended December 31, 2013, 2012 and 2011, the Company reduced its taxes payable by $8,781,$9,603 and $8,990 respectively, as a result of the exercise of non-qualified stock options, the vesting of restricted stock units, and the disqualifying disposition of incentive stock options.  The excess tax benefit associated with equity-based compensation of $3,765,$5,033 and $4,763 for the years ended December 31, 2013, 2012 and 2011, respectively, was recorded in additional paid-in capital. 

The differences between the Company’s income tax provision as presented in the accompanying Consolidated Statements of Net Income and income tax provision computed at the federal statutory rate consist of the items shown in the following table as a percentage of pre-tax income: 

	Years Ended December 31,
	2013		2012		2011
Income tax provision at the statutory rate		35.0%		35.0%		35.0%
State taxes, net of federal benefit		3.7		3.6		3.7
Deferred income tax liability adjustments		-		1.0		-
Noncontrolling interests		-		(0.1)		(0.1)
Other		0.2		0.3		0.6
		38.9%		39.8%		39.2%

During the year ended December 31, 2012, the Deferred income tax liability adjustments, due primarily to changes in the geographical apportionment of the Company’s state income taxes associated with the R360 acquisition, resulted in an increase to tax expense of $2,602. 

At December 31, 2013 and 2012, the Company did not have any significant federal or state net operating loss carryforwards.

The Company and its subsidiaries are subject to U.S. federal income tax as well as to income tax of multiple state jurisdictions.  The Company has concluded all U.S. federal income tax matters for years through 2009.  All material state and local income tax matters have been concluded for years through 2008.

In September 2013, the U.S. Treasury Department issued final regulations governing the income tax treatment of acquisitions, dispositions, and repairs of tangible property, effective for tax years beginning in 2014.  The impact of these final regulations is not material to the Company’s financial statements.  

The Company did not have any unrecognized tax benefits recorded at December 31, 2013 or 2012.  The Company does not anticipate the total amount of unrecognized tax benefits will significantly change by December 31, 2014.  The Company recognizes interest and/or penalties related to income tax matters in income tax expense.  

The following is a rollforward of the Company’s unrecognized tax benefits from January 1, 2011 to December 31, 2013:

10.GAIN FROM LITIGATION SETTLEMENT 

In November 2010, the Company’s subsidiary, Potrero Hills Landfill, Inc. (“PHLF”), which owns and operates the Potrero Hills Landfill in Solano County, California, initiated contractual arbitration proceedings with Judicial Arbitration and Mediation Services, Inc. in San Francisco against The Ratto Group of Companies, Inc. (“Ratto”) alleging Ratto’s breach of the parties’ Solid Waste Disposal Agreement.

The case was arbitrated in February and March 2012 before the Honorable Fern Smith (ret.).  On August 13, 2012, Judge Smith issued her Final Award finding that Ratto had breached the Solid Waste Disposal Agreement by failing to include PHLF in its 2010 bid to Sonoma County and awarding PHLF lost profits, attorney’s fees and costs.  Pursuant to this Final Award, on September 13, 2012, Ratto remitted to PHLF $3,551, which was recorded as Gain from litigation settlement in the Consolidated Statements of Net Income.

Acquisitions [Abstract]

Acquisitions

3.ACQUISITIONS

The Company recognizes, separately from goodwill, the identifiable assets acquired and liabilities assumed at their estimated acquisition date fair values.  The Company measures and recognizes goodwill as of the acquisition date as the excess of:  (a) the aggregate of the fair value of consideration transferred, the fair value of any noncontrolling interest in the acquiree (if any) and the acquisition date fair value of the Company's previously held equity interest in the acquiree (if any), over (b) the fair value of assets acquired and liabilities assumed.  If information about facts and circumstances existing as of the acquisition date is incomplete by the end of the reporting period in which a business combination occurs, the Company will report provisional amounts for the items for which the accounting is incomplete.  The measurement period ends once the Company receives the information it was seeking; however, this period will not exceed one year from the acquisition date.  Any material adjustments recognized during the measurement period will be reflected retrospectively in the consolidated financial statements of the subsequent period.  The Company recognizes acquisition-related costs as expense. 

R360 Acquisition

On October 25, 2012, the Company completed the acquisition of all of the outstanding equity interests in certain entities that, together with the operating subsidiaries of such entities, hold the business of R360 Environmental Solutions, Inc. (“R360”) for total cash consideration of $1,338,344, net of cash acquired, the assumption of outstanding debt totaling $9,306 and the assumption of contingent consideration totaling $37,293. The acquisition was funded with available cash and with borrowings of $475,000 under the Company’s senior revolving credit facility and of $800,000 under an uncollateralized term loan facility.  The R360 business consists of E&P landfills, E&P liquid waste injection wells, E&P waste treatment and recovery facilities and oil recovery facilities at 24 operating locations across Louisiana, New Mexico, North Dakota, Oklahoma, Texas and Wyoming.  The R360 acquisition enabled the Company to significantly expand its scope of E&P waste services and contributed towards the achievement of the Company’s strategy to expand through acquisitions.

The results of operations of the R360 business have been included in the Company’s consolidated financial statements from its acquisition date.  Total revenues during the period from October 25, 2012 to December 31, 2012, generated from the R360 operations and included within consolidated revenues were $40,190.  Total pre-tax earnings during the period from October 25, 2012 to December 31, 2012, generated from the R360 operations and included within consolidated income before income taxes, were $8,669.

The following table summarizes the consideration transferred to acquire the R360 business and the amounts of identifiable assets acquired and liabilities assumed:

Fair value of consideration transferred:
Cash	$	1,338,344
Debt assumed*		9,306
Contingent consideration		37,293
		1,384,943

Goodwill	$	445,925

____________________

*Debt assumed was paid at close of acquisition.

Contingent consideration consists of obligations assumed by the Company related to previous acquisitions completed by R360, and consists of the following:

Prairie Disposal contingent consideration	$	24,376
Oilfield Holdings contingent consideration		8,000
Calpet contingent consideration		4,176
Claco Services contingent consideration		741
	$	37,293

The Prairie Disposal contingent consideration represents the fair value of up to $25,000 of contingent consideration payable to the former owners of Prairie Disposal, LLC and Prairie Liquids, LLC (“Prairie”) based on the future achievement of certain milestones over an expectedtwo-year period. The fair value of the contingent consideration was determined using probability assessments of the expected future cash flows over the two-year period in which the obligation is expected to be settled, and applied a discount rate of 2.0%.  As of December 31, 2013, the fair value of the obligation increased to $24,944 due to the accretion of interest on the liability.  Any changes in the fair value of the contingent consideration subsequent to the acquisition date will be charged or credited to expense until the contingency is settled. 

The Oilfield Holdings contingent consideration represents the fair value of up to $8,000 payable to the former owners of Oilfield Holdings if R360 completed a qualifying cash event, as defined in the Oilfield Holdings purchase agreement. A qualifying cash event included the sale of R360. Payment of the contingent consideration required the qualifying cash event to generate a return on investment above a certain minimum threshold. The Company’s R360 acquisition generated a return on investment that resulted in the payment of the $8,000 liability to the former owners of Oilfield Holdings in November 2012.

The Calpet contingent consideration represents the fair value of up to $4,221 payable to the former owners of Calpet, LLC based on the future achievement of revenue targets through June 2013. The fair value of the contingent consideration was determined using probability assessments of the expected future cash flows over the one-year period in which the obligations is expected to be settled, and applied a discount rate of 2.0%.  During the year ended December 31, 2013, $2,500 of the contingent consideration was earned and paid to the former owners and $1,250 of the contingent consideration was not earned and credited to expense. Any changes in the fair value of the $471 remaining contingent consideration obligation at December 31, 2013 will be charged or credited to expense until the contingency is settled.

The Claco Services contingent consideration represents the fair value of up to $750 payable to the former owners of Claco Services through December 2013. The Company paid $375 of this assumed liability in both December 2012 and December 2013.

The R360 acquisition resulted in goodwill acquired totaling $395,339, which is expected to be deductible for tax purposes.  The goodwill is attributable to growth opportunities, at existing R360 operations as well additional acquisitions of companies providing non-hazardous oilfield waste treatment and disposal services, and synergies that are expected to arise as a result of the acquisition.

Cash consideration for the R360 acquisition included payment for the estimated net working capital of $18,906, as defined in the acquisition agreement, which was subject to final adjustment subsequent to the close of the acquisition. In March 2013, Waste Connections received $18,000 from the former owners of R360 due to the final adjustment to the net working capital that was estimated at the closing date.

The gross amount of trade receivables due under contracts was  $52,777, of which $2,616was expected to be uncollectible.  The Company did not acquire any other class of receivable as a result of the R360 acquisition. 

The Company incurred $2,655, of acquisition-related costs for the R360 acquisition.  These expenses are included in Selling, general and administrative expenses in the Company’s Consolidated Statements of Net Income. 

Other Acquisitions

The Company acquired eight individually immaterial non-hazardous solid waste collection businesses during the year ended December 31, 2013.  The total acquisition-related costs incurred for these acquisitions was $1,946. These expenses are included in Selling, general and administrative expenses in the Company’s Consolidated Statements of Net Income. 

In July 2012, the Company completed the acquisition of 100% of the interests in the operations of SKB Environmental, Inc. (“SKB”), a provider of solid waste transfer and disposal services in Minnesota, in exchange for total consideration of $86,763.  Pursuant to the stock purchase agreement, the Company was required to remit additional consideration to the former shareholders of SKB if the acquired operations exceeded earnings targets specified in the stock purchase agreement over a one-year earn out period ending June 30, 2013.  The Company computed the fair value of the contingent consideration at the purchase date to be $20,711, based upon probability assessments of the expected future cash flows over the one-year period in which the obligation was expected to be settled, to which the Company had applied a discount rate of 2.0%.  Based upon the actual earnings of SKB over the one-year earn out period, the final additional consideration was $25,768, which the Company paid in July 2013. The difference between the final contingent consideration paid and the fair value of the contingent consideration at the purchase date was charged to expense in the Company’s Consolidated Statements of Net Income.   

On March 1, 2012, the Company completed the acquisition of 100% of the interests in the operations of Alaska Pacific Environmental Services Anchorage, LLC and Alaska Green Waste Solutions, LLC (together, “Alaska Waste”).  Alaska Waste provides solid waste collection, transfer and composting services in Anchorage, the Mat-Su Valley, Fairbanks, the Kenai Peninsula and Kodiak Island.  The Company paid $133,402 for the purchased operations.  Pursuant to the asset purchase agreement, the Company is required to remit up to $4,000 of additional consideration to the former owners of Alaska Waste if new business is generated through the privatization of certain markets currently serviced by municipalities.  The Company computed the fair value of the contingent consideration at the purchase date to be $602, based upon probability assessments of the expected future cash flows over the two-year period in which the obligation is expected to be settled, to which the Company applied a discount rate of 2.8%.  As of December 31, 2013, the obligation recognized at the purchase date has not materially changed.  Any changes in the fair value of the contingent consideration subsequent to the acquisition date will be charged or credited to expense until the contingency is settled. 

In addition to the acquisitions of SKB and Alaska Waste, the Company acquired 10 individually immaterial non-hazardous solid waste collection, transfer, disposal and E&P businesses during the year ended December 31, 2012.  The total acquisition-related costs incurred for these acquisitions was $2,658. These expenses are included in Selling, general and administrative expenses in the Company’s Consolidated Statements of Net Income. 

In August 2011, the Company’s subsidiary, Capital Region Landfills, Inc. (“CRL”), entered into an agreement with the Town of Colonie, a municipal corporation of the state of New York, to operate a municipal solid waste disposal facility (the “Colonie Landfill”) for an initial term of 25 years.  The agreement became effective on September 19, 2011.  As consideration for operating equipment and the right to operate the Colonie Landfill, CRL remitted an initial payment of $23,860.  CRL is also required to remit up to $55,470 of additional consideration over the term of the agreement, comprised of $11,500 payable over a five-year period ending September 2016 and up to $43,970 payable over the term of the agreement if certain expansion criteria are met and certain annual tonnage targets are exceeded as specified in the operating agreement.  The Company computed the fair value of the additional consideration using probability assessments of the expected future cash flows over estimated payment terms of four to 25 years, to which the Company applied discount rates ranging from 2.5% to 5.0%, resulting in a total obligation recognized at the effective date of $32,928, which consisted of $10,656 recorded as Notes issued to sellers and $22,272 recorded as contingent consideration in Long-term contingent consideration.  CRL is also responsible for all final capping, closure and post-closure liabilities and estimates the total obligation in current dollars to be $21,287, the net present value of which is $1,429.  This obligation was recorded in Other long-term liabilities.  The obligation for contingent consideration recognized at the purchase date increased $1,144,  $1,086 and $301 during the years ended December 31, 2013, 2012 and 2011, respectively, due to the accretion of interest on the liability.  Any changes in the fair value of the contingent consideration subsequent to the acquisition date will be charged or credited to income until the contingency is settled.

On April 1, 2011, the Company completed the acquisition of a 100% interest in Hudson Valley Waste Holding, Inc., and its wholly-owned subsidiary, County Waste and Recycling Service, Inc. (collectively, “County Waste”).  As part of this acquisition, the Company acquired a 50% interest in Russell Sweepers, LLC, a provider of sweeper services, resulting in a 50% noncontrolling interest that was recognized at fair value on the purchase date.  The operations include six collection operations, three transfer stations and one recycling facility across six markets in New York and Massachusetts.  The Company paid $299,000 for the purchased operations plus amounts paid for the purchase of accounts receivable and other prepaid assets and estimated working capital, which amounts were subject to post-closing adjustments.  No other consideration, including contingent consideration, was transferred by the Company to acquire these operations.  Total revenues during the year ended December 31, 2011, generated from the County Waste operations and included within consolidated revenues were $93,713.  Total pre-tax earnings during the year ended December 31, 2011, generated from the County Waste operations and included within consolidated income before income taxes were $7,276.   

In addition to the County Waste acquisition and Colonie Landfill transaction, the Company acquired 11 individually immaterial non-hazardous solid waste collection and transfer businesses during the year ended December 31, 2011.  The total acquisition-related costs incurred for these acquisitions was $1,744. These expenses are included in Selling, general and administrative expenses in the Company’s Consolidated Statements of Net Income. 

The results of operations of the acquired businesses have been included in the Company’s consolidated financial statements from their respective acquisition dates.  The Company expects these acquired businesses to contribute towards the achievement of the Company’s strategy to expand through acquisitions.  Goodwill acquired is attributable to the synergies and ancillary growth opportunities expected to arise after the Company’s acquisition of these businesses. 

The following table summarizes the consideration transferred to acquire these businesses and the amounts of identifiable assets acquired, liabilities assumed and noncontrolling interests associated with businesses acquired at the acquisition date for acquisitions consummated in the years ended December 31, 2013, 2012 and 2011:

*Debt assumed as part of 2011 and 2012 acquisitions was paid at close of acquisition.

Goodwill acquired in 2013 totaling $39,731 is expected to be deductible for tax purposes.   The 2012 acquisitions of SKB, Alaska Waste and other individually immaterial non-hazardous solid waste collection, transfer, disposal and E&P businesses resulted in goodwill acquired in 2012 totaling $74,241, which is expected to be deductible for tax purposes.  Goodwill acquired in 2011 totaling $24,242 is expected to be deductible for tax purposes.  

The fair value of acquired working capital related to three individually immaterial acquisitions completed during the year ended December 31, 2013, is provisional pending receipt of information from the acquirees to support the fair value of the assets acquired and liabilities assumed.  Any adjustments recorded relating to finalizing the working capital for these three acquisitions are not expected to be material to the Company’s financial position. 

The gross amount of trade receivables due under contracts acquired during the year ended December 31, 2013, was $414, of which $203 was expected to be uncollectible.  The gross amount of trade receivables due under contracts acquired with the acquisitions of SKB, Alaska Waste and other individually immaterial non-hazardous solid waste collection, transfer, disposal and E&P businesses during the year ended December 31, 2012, was  $10,984, of which $110was expected to be uncollectible.  The gross amount of trade receivables due under contracts acquired during the year ended December 31, 2011, was  $10,232, of which $619was expected to be uncollectible.  The Company did not acquire any other class of receivable as a result of the acquisition of these businesses. 

The Company paid $4,099 of contingent consideration during the year ended December 31, 2012, related to the achievement of earnings targets for certain acquisitions closed in 2011 and 2010.  The Company paid $500 of contingent consideration during the year ended December 31, 2011, which primarily represented the achievement of earnings targets for an acquisition closed in 2010.

Segment Reporting [Abstract]

Segment Reporting

15.SEGMENT REPORTING 

The Company’s revenues are generated from the collection, transfer, recycling and disposal of non-hazardous solid waste and the treatment, recovery and disposal of non-hazardous E&P waste.  No single contract or customer accounted for more than 10% of the Company’s total revenues at the consolidated or reportable segment level during the periods presented.

Prior to October 2012, the Company managed its operations through three geographic operating segments (Western, Central and Eastern), which were also its reportable segments.  In October 2012, as a result of the R360 acquisition described in Note 3, the Company realigned its reporting structure and created a fourth operating segment, the E&P segment, which includes the majority of the Company’s E&P waste treatment and disposal operations.  As a result, the Company’s three geographic operating segments and its E&P segment comprise the Company’s reportable segments.  Additionally, in January 2013, the Company transferred an E&P operation in Louisiana, owned by the Company prior to the R360 acquisition, from its Central segment to its E&P segment. Each operating segment is responsible for managing several vertically integrated operations, which are comprised of districts.  The segment information presented herein reflects the addition of the new E&P segment and the transfer of the Company’s E&P operation in Louisiana to the E&P segment.  Under the current structure, the Company’s Western segment is comprised of operating locations in Alaska, California, Idaho, Montana, Nevada, Oregon, Washington and western Wyoming; the Company’s Central segment is comprised of operating locations in Arizona, Colorado, Kansas, Louisiana, Minnesota, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, Utah and eastern Wyoming; and the Company’s Eastern segment is comprised of operating locations in Alabama, Illinois, Iowa, Kentucky, Massachusetts, Michigan, Mississippi, New York, North Carolina, South Carolina and Tennessee.  The E&P segment is comprised of the Company’s E&P operations in Louisiana, New Mexico, North Dakota, Oklahoma, Texas, Wyoming and along the Gulf of Mexico.

The Company’s Chief Operating Decision Maker (“CODM”) evaluates operating segment profitability and determines resource allocations based on several factors, of which the primary financial measure is EBITDA. The Company defines EBITDA as earnings before interest, taxes, depreciation, amortization, gain (loss) on disposal of assets, loss on prior office leases and other income (expense).  EBITDA is not a measure of operating income, operating performance or liquidity under generally accepted accounting principles and may not be comparable to similarly titled measures reported by other companies.  The Company’s management uses EBITDA in the evaluation of segment operating performance as it is a profit measure that is generally within the control of the operating segments.  A reconciliation of EBITDA to Income before income tax provision is included at the end of this Note 15.

Summarized financial information concerning the Company’s reportable segments for the years ended December 31, 2013, 2012 and 2011, is shown in the following tables:

Commitments and Contingencies

11.COMMITMENTS AND CONTINGENCIES 

COMMITMENTS 

Leases 

The Company leases certain facilities and certain equipment under non-cancelable operating leases for periods ranging from one to 45 years, with renewal options for certain leases.  The Company’s total rent expense under operating leases during the years ended December 31, 2013, 2012 and 2011, was $30,893,  $19,424 and $13,519, respectively. 

As of December 31, 2013, future minimum lease payments, by calendar year, are as follows: 

2014	$	18,343
2015		16,457
2016		14,773
2017		13,210
2018		10,595
Thereafter		75,203
	$	148,581

Financial Surety Bonds 

The Company uses financial surety bonds for a variety of corporate guarantees.  The two largest uses of financial surety bonds are for municipal contract performance guarantees and asset closure and retirement requirements under certain environmental regulations.  Environmental regulations require demonstrated financial assurance to meet final capping, closure and post-closure requirements for landfills.  In addition to surety bonds, these requirements may also be met through alternative financial assurance instruments, including insurance, letters of credit and restricted asset deposits. 

At December 31, 2013 and 2012, the Company had provided customers and various regulatory authorities with surety bonds in the aggregate amount of approximately $304,416 and $277,841, respectively, to secure its asset closure and retirement requirements and $89,196 and $83,738, respectively, to secure performance under collection contracts and landfill operating agreements. 

The Company owns a 9.9% interest in a company that, among other activities, issues financial surety bonds to secure landfill final capping, closure and post-closure obligations for companies operating in the solid waste industry.  The Company accounts for this investment under the cost method of accounting.  There have been no identified events or changes in circumstances that may have a significant adverse effect on the fair value of the investment.  This investee company and the parent company of the investee have written financial surety bonds for the Company, of which $163,187 and$153,337 were outstanding as of December 31, 2013 and 2012, respectively.  The Company’s reimbursement obligations under these bonds are secured by a pledge of its stock in the investee company. 

Unconditional Purchase Obligations

At December 31, 2013, the Company’s unconditional purchase obligations consist of multiple fixed-price fuel purchase contracts under which it has 4.6 million gallons remaining to be purchased for a total of $16,089, plus taxes and transportation upon delivery.  These fuel purchase contracts expire on or before December 31, 2014.

CONTINGENCIES 

Environmental Risks

The Company expenses costs incurred to investigate and remediate environmental issues unless they extend the economic useful life of related assets.  The Company records liabilities when it is probable that an obligation has been incurred and the amounts can be reasonably estimated.  The remediation reserves cover anticipated costs, including remediation of environmental damage that waste facilities may have caused to neighboring landowners or residents as a result of contamination of soil, groundwater or surface water, including damage resulting from conditions existing prior to the Company’s acquisition of such facilities.  The Company’s estimates are based primarily on investigations and remediation plans established by independent consultants, regulatory agencies and potentially responsible third parties.  The Company does not discount remediation obligations.  At December 31, 2013 and 2012, the current portion of remediation reserves was $3,226 and $4,097, respectively, which is included in Accrued liabilities in the Consolidated Balance Sheets.  At December 31, 2013 and 2012, the long-term portion of remediation reserves was $725 and$1,214, respectively, which is included in Other long-term liabilities in the Consolidated Balance Sheets. The Company’s liabilities for remediation reserves were assumed in the R360 acquisition. The Company did not have liabilities for remediation reserves recorded at December 31, 2011.  Any substantial increase in the liabilities for remediation of environmental damage incurred by the Company could have a material adverse effect on the Company’s financial condition, results of operations or cash flows. 

Legal Proceedings

In the normal course of its business and as a result of the extensive governmental regulation of the solid waste and E&P waste industries, the Company is subject to various judicial and administrative proceedings involving federal, state or local agencies.  In these proceedings, an agency may seek to impose fines on the Company or to revoke or deny renewal of an operating permit held by the Company.  From time to time, the Company may also be subject to actions brought by special interest or other groups, adjacent landowners or residents in connection with the permitting and licensing of landfills, transfer stations, and E&P waste treatment, recovery and disposal operations, or alleging environmental damage or violations of the permits and licenses pursuant to which the Company operates. 

In addition, the Company is a party to various claims and suits pending for alleged damages to persons and property, alleged violations of certain laws and alleged liabilities arising out of matters occurring during the normal operation of the waste management business.  Except as noted in the matters described below, as of December 31, 2013, there is no current proceeding or litigation involving the Company or its property that the Company believes could have a material adverse impact on its business, financial condition, results of operations or cash flows.

Chaparral, New Mexico Landfill Permit Litigation

The Company’s subsidiary, High Desert Solid Waste Facility, Inc. (formerly known as Rhino Solid Waste, Inc.) (“HDSWF”), owns undeveloped property in Chaparral, New Mexico, for which it sought a permit to operate a municipal solid waste landfill.  The New Mexico Environment Department (the “Department”) approved the permit for the facility on January 30, 2002.  Colonias Development Council (“CDC”), a nonprofit organization, appealed the Department’s decision to the courts of New Mexico, alleging primarily that the Department failed to consider the social impact of the landfill on the community of Chaparral, and failed to consider regional planning issues.  On July 18, 2005, in Colonias Dev. Council v. Rhino Envtl. Servs., Inc. (In re Rhino Envtl. Servs.), 2005 NMSC 24, 117 P.3d 939, the New Mexico Supreme Court remanded the matter back to the Department to conduct a limited public hearing on certain evidence that CDC claimed was wrongfully excluded from consideration by the hearing officer, and to allow the Department to reconsider the evidence already proffered concerning the impact of the landfill on the surrounding community’s quality of life.  In July 2007, the Department, CDC, the Company and Otero County signed a stipulation requesting a postponement of the limited public hearing to allow the Company time to explore a possible relocation of the landfill to a new site.  Since 2007, the Department has issued several orders postponing the limited public hearing, and on October 17, 2012, it granted a request by the parties to hold the limited public hearing in abeyance until further notice.

In July 2009, HDSWF purchased approximately 325 acres of undeveloped land comprising a proposed new site from the State of New Mexico.  HDSWF filed a formal landfill permit application for the new site with the Department on September 17, 2010.  On September 12, 2011, the Department deemed the permit application complete and a public hearing on the matter had been tentatively scheduled for April 9, 2012, in Chaparral, New Mexico.  On November 9, 2011, HDSWF filed a motion with the Department to hold in abeyance indefinitely the notice for public hearing and the permit hearing, and HDSWF agreed to provide the Department with at least 120 days’ prior notice of any desired, future permit hearing.  The Department granted the motion.  HDSWF requested the abeyance to defer capital expenditures related to permitting the new site until mid to late 2014, when HDSWF expects to have a better understanding of several current market conditions and regulatory factors that affect the timing and feasibility of the project.  These conditions and factors include: the status of the Company’s Solid Waste Disposal and Operating Agreement for the collection and disposal of solid waste generated within the City of El Paso, effective April 28, 2004, which has a 10-year term; the status of El Paso Disposal, LP’s Solid Waste Franchise Agreement for the collection of solid waste generated within the City of El Paso, effective September 1, 2011, which has a 40-month term; and whether certain closed or non-operating disposal facilities in the El Paso market area are reopened and whether those facilities are operated by private or public entities.  On February 4, 2014, the Mayor of the City of El Paso approved and the City Council passed an ordinance amending the El Paso City Code to, among other things, rescind the City’s flow control requirement directing waste collected within its boundaries to City-owned disposal facilities, which was scheduled to become effective on September 1, 2014.

At December 31, 2013, the Company had $11,778 of capitalized expenditures related to this landfill development project.  Depending on the outcome of the market conditions and regulatory factors described above, the Company may decide in mid to late 2014 to abandon the project and expense the $11,778 of capitalized expenditures, less the recoverable value of the undeveloped properties and other amounts recovered, which would likely have a material adverse effect on the Company’s results of operations for that period.  Alternatively, if the outcome of the market conditions and regulatory factors described above is such that the Company believes the market for disposal of solid waste generated in the City of El Paso will remain competitive, HDSWF may decide in mid to late 2014 to resume its permitting process for the new site.  Under those circumstances, if the Department ultimately denies the landfill permit application for the new site, HDSWF intends to actively resume its efforts to enforce the previously issued landfill permit for the original site in Chaparral.  If the Company is ultimately issued a permit to operate the landfill at the new site purchased in July 2009, the Company will be required to expense in a future period $10,324 of capitalized expenditures related to the original Chaparral property, less the recoverable value of that undeveloped property and other amounts recovered, which would likely have a material adverse effect on the Company’s results of operations for that period.  If the Company instead is ultimately issued a permit to operate the landfill at the original Chaparral property, the Company will be required to expense in a future period $1,454 of capitalized expenditures related to the new site purchased in July 2009, less the recoverable value of that undeveloped property and other amounts recovered.  If the Company is not ultimately issued a permit to operate the landfill at either one of the two sites, the Company will be required to expense in a future period the $11,778 of capitalized expenditures, less the recoverable value of the undeveloped properties and other amounts recovered, which would likely have a material adverse effect on the Company’s results of operations for that period.

Harper County, Kansas Landfill Permit Litigation

The Company opened a municipal solid waste landfill in Harper County, Kansas in January 2006, following the issuance by the Kansas Department of Health and Environment (“KDHE”) of a permit to operate the landfill.  The landfill has operated continuously since that time.  In 2005, landfill opponents (the “Plaintiffs”) filed a suit (Board of Comm’rs of Sumner County, Kansas, Tri-County Concerned Citizens and Dalton Holland v. Roderick Bremby, Sec’y of the Kansas Dep’t of Health and Env’t, et al.) in the District Court of Shawnee County, Kansas, seeking a judicial review of KDHE’s decision to issue the permit, alleging that a site analysis prepared for the Company and submitted to KDHE as part of the process leading to the issuance of the permit was deficient in several respects.  The action sought to stay the effectiveness of the permit and to nullify it.  The Company intervened in this lawsuit shortly after it was filed.  In June 2012, the District Court denied the Plaintiffs’ demand for revocation of the permit, and affirmed KDHE’s decision that the issuance of the permit met all applicable regulatory requirements.  The Plaintiffs filed an appeal with the Kansas Court of Appeals.  On September 13, 2013, the Kansas Court of Appeals affirmed KDHE’s issuance of the landfill permit to the Company.  On October 15, 2013, the Plaintiffs petitioned the Kansas Supreme Court to review the decision of the Court of Appeals, which review is discretionary.  To date, the Kansas Supreme Court has not decided if it will review this matter.  The Company believes that it will ultimately prevail in this matter, and the Company will continue to have the right to operate the landfill during the pendency of any further appeal.  Only in the event that a final, materially adverse determination with respect to the permit is received would there likely be a material adverse effect on the Company’s reported results of operations in the future.  If as a result of this litigation, after exhausting all appeals, the Company was unable to continue to operate the landfill, the Company estimates that it would be required to record a pre-tax impairment charge of approximately $20,000 to reduce the carrying value of the landfill to its estimated fair value.  In addition, the Company estimates the current annual impact to its pre-tax earnings that would result if it was unable to continue to operate the landfill would be approximately $3,400 per year. 

Solano County, California Measure E/Landfill Expansion Litigation

The Company and one of its subsidiaries, Potrero Hills Landfill, Inc. (“PHLF”), were named as real parties in interest in an amended complaint captioned Sustainability, Parks, Recycling and Wildlife Legal Defense Fund v. County of Solano, which was filed in the Superior Court of California, County of Solano, on July 9, 2009 (the original complaint was filed on June 12, 2009).  This lawsuit sought to compel Solano County to comply with Measure E, a ballot initiative and County ordinance passed in 1984 that the County has not enforced against PHLF since at least 1992.  Measure E directed in part that Solano County shall not allow the importation into the County of any solid waste which originated or was collected outside the County in excess of 95,000 tons per year.  The Sustainability, Parks, Recycling and Wildlife Legal Defense Fund (“SPRAWLDEF”) lawsuit also sought to overturn Solano County’s approval of the use permit for the expansion of the Potrero Hills Landfill and the related Environmental Impact Report (“EIR”), arguing that both violated Measure E and that the EIR violated the California Environmental Quality Act (“CEQA”).  Two similar actions seeking to enforce Measure E, captioned Northern California Recycling Association v. County of Solano and Sierra Club v. County of Solano, were filed in the same court on June 10, 2009, and August 10, 2009, respectively.  The Northern California Recycling Association (“NCRA”) case did not name the Company or any of its subsidiaries as parties and did not contain any CEQA claims, but sought to enforce Measure E and overturn the use permit for the expansion.  The Sierra Club case named PHLF as a real party in interest, and sought to overturn the use permit for the expansion of the landfill on Measure E grounds (but did not raise CEQA claims). 

On May 12, 2010, the Solano County Superior Court issued a written opinion addressing all three cases.  The Court upheld Measure E in part by judicially rewriting the law, and then issued a writ of mandamus directing Solano County to enforce Measure E as rewritten.  The Court decided that it could cure the law’s discrimination against out-of-county waste by revising Measure E to only limit the importation of waste into Solano County from other counties in California, but not from other states.  In the same opinion, the Superior Court rejected the requests from petitioners in the cases for a writ of administrative mandamus to overturn the use permit approved by Solano County in June 2009 for the expansion of PHLF’s landfill, thereby leaving the expansion use permit in place. 

In December 2010, the Superior Court entered final judgments and writs of mandamus in the three cases, and Solano County, the Company, PHLF and numerous waste hauling company intervenors filed notices of appeal, which stayed the judgments and writs pending the outcome of the appeal.  Petitioners Sierra Club and SPRAWLDEF cross-appealed the Court’s ruling denying their petitions for writs to overturn PHLF’s use permit for the expansion. 

As part of the final judgments, the Solano County Superior Court retained jurisdiction over any motions for attorneys’ fees under California's Private Attorney General statute.  Petitioners NCRA, SPRAWLDEF and Sierra Club each filed a bill of costs and a motion for attorney fees totaling $771.  On May 31, 2011, the court issued a final order awarding petitioners $452 in attorneys’ fees, $411 of which relates to the SPRAWLDEF and Sierra Club cases in which the Company or PHLF is a named party.  The court allocated 50% of the fee amount to PHLF, none of which the Company recorded as a liability at December 31, 2013.  The Company and Solano County appealed this attorneys’ fees order in July 2011, which stayed the fee order.  As explained below, in January 2014 the Court of Appeal reversed the attorney fee award.

On September 25, 2012, Governor Jerry Brown signed into law Assembly Bill 845 (“AB 845”), an act of the California Legislature, effective January 1, 2013.  AB 845 expressly prohibits counties from restricting or limiting the importation of solid waste into a privately owned facility in a county based on the waste’s place of origin.  In light of AB 845, the Company filed a motion to dismiss the cross appeals and reverse and remand the portions of the judgments rendered in petitioners’ favor regarding enforcement and implementation of Measure E by Solano County, including petitioners’ recovery of costs, on mootness grounds.

On July 31, 2013, the Court of Appeal granted the Company’s motion and ruled that AB 845 preempted Measure E and therefore precluded the writ of mandate enforcing Measure E as judicially rewritten.  The Court reversed the judgment and writ of mandate, and directed the trial court to dismiss the petitions.  The Court also dismissed on mootness grounds the cross-appeals by the petitioners of the trial court’s denial of their request for a writ of mandate vacating the use permit for the expansion.  Regarding the trial court’s award of attorney fees to the petitioners, the Court of Appeal stated that petitioners were no longer successful parties under California law and “the award of attorney fees must necessarily be reversed.”  Because the appeal of the attorney fees award was a separate case from the merits appeal, the Court’s ruling did not include an order regarding the fees award.  On August 19, 2013, the Company filed a Motion for Summary Reversal of Judgment Granting Attorney’s Fees in light of the Court of Appeal’s merits ruling, which the Court deferred until a remittitur was issued in the underlying merits appeal.  On September 9, 2013, Sierra Club and SPRAWLDEF filed petitions for review of the Court of Appeal’s decision with the California Supreme Court.  On October 23, 2013, the Supreme Court denied the petitions and issued a remittitur directing each party to bear its own costs on appeal.  On January 22, 2014, the Court of Appeal granted the Company’s pending motion and reversed the attorney fee award.  On January 23, 2014, the Solano County Superior Court dismissed the petitions filed by SPRAWLDEF, Sierra Club, and NCRA in accordance with the Court of Appeal’s decision, which officially concluded the litigation in the Company’s favor.

On December 17, 2010, SPRAWLDEF and one its members filed a petition for writ of mandate in San Francisco Superior Court seeking to overturn the October 2010 approval of the marsh development permit issued by the San Francisco Bay Conservation and Development Commission (“BCDC”) for PHLF’s landfill expansion, alleging that the approval is contrary to the Suisun Marsh Protection Act.  The petition, captioned SPRAWLDEF v. San Francisco Bay Conservation and Development Commission, names BCDC as a respondent and the Company as the real party in interest.  The San Francisco Superior Court stayed the action and, on April 5, 2012, transferred the case to Solano County Superior Court, citing that court’s experience in the related CEQA case and judicial economy.  On June 5, 2012, Solano County Superior Court assigned the case to Judge Beeman.  On November 29, 2012, the Superior Court issued an order finding that the administrative record before BCDC did not contain sufficient evidence regarding net profits for the proposed project or the alternative to support the agency’s finding that the alternative was economically infeasible.  The Superior Court therefore issued a writ of mandamus and final judgment on January 14, 2013, setting aside the BCDC permit and remanding it back to the agency for further consideration.  Both the Company and BCDC filed notices of appeal, staying execution of the writ and judgment pending the appeal.  The Court of Appeal held oral argument on the appeal on February 4, 2014, and took the matter under submission.  The County of Solano, Suisun Resource Conservation District, California Refuse Recycling Council and Napa-Vallejo Waste Management Authority each filed amici briefs in this case on behalf of Appellants BCDC and the Company.  At this point the Company is not able to determine the likelihood of any outcome in this matter.

On June 10, 2011, June Guidotti, a property owner adjacent to PHLF, and SPRAWLDEF and one of its members, each filed administrative petitions for review with the State Water Resources Control Board (“State Board”) seeking to overturn a May 11, 2011 Order No. 2166-(a) approving waste discharge requirements issued by the San Francisco Bay Regional Water Quality Control Board (“Regional Board”) for PHLF’s landfill expansion, alleging that the order is contrary to the State Board’s Title 27 regulations authorizing waste discharge requirements for landfills, and in the case of the SPRAWLDEF petition, further alleging that the Regional Board’s issuance of a Clean Water Act section 401 certification is not supported by an adequate alternatives analysis as required by the federal Clean Water Act.  The Regional Board is preparing the administrative record of its decision to issue Order 2166-(a) to be filed with the State Board as well as its response to the petitions for review.  It is anticipated that the Regional Board will vigorously defend its actions and seek dismissal of the petitions for review.  A hearing date has not yet been set on either petition, and the State Board has held both the Guidotti and SPRAWLDEF petitions in abeyance at the petitioners’ requests.  At this point, the Company is not able to determine the likelihood of any outcome in this matter.

If as a result of any of the matters described above, after exhausting all appeals, PHLF’s marsh development permit is permanently rescinded, the Company estimates that it would be required to recognize a pre-tax impairment charge of approximately $11,000 to reduce the carrying value of PHLF to its estimated fair value.

Madera County, California Materials Recovery Facility Contract Litigation

The Company’s subsidiary, Madera Disposal Systems, Inc. (“MDSI”) was named in a complaint captioned County of Madera vs. Madera Disposal Systems, Inc., et al, filed in Madera County Superior Court (Case No. MCV 059402) on March 5, 2012, and subsequently transferred to Fresno County Superior Court.  Madera County alleges in the complaint that from 2007 through 2010, MDSI breached a contract with the County for the operation of a materials recovery facility by withholding profits from facility operations in excess of those authorized by the contract.  The County further alleges that the breach gives the County the unilateral right to terminate all of its contracts with MDSI, including contracts for (1) the collection of residential and commercial waste in the unincorporated parts of the County, (2) operation of the materials recovery facility, (3) operation of the North Fork Transfer Station and (4) operation of the Fairmead Landfill.  The County seeks monetary damages of $2,962 from MDSI, plus pre-judgment interest at 10% per annum.

MDSI had been under contract with the County to collect residential and commercial waste and operate the county-owned Fairmead Landfill continuously since at least 1981.  In 1993, MDSI contracted with the County to construct and operate a materials recovery facility for the County on the premises of the Fairmead Landfill.  After it entered into the materials recovery facility contract, MDSI entered into new contracts with the County for waste collection and landfill operation to run concurrently with the materials recovery facility contract.  In 1998, MDSI and the County agreed to extend the terms of the County contracts until November 10, 2012, with MDSI holding a unilateral option to extend the contracts for an additional five-year term.

In March 2011, the County issued a Notice of Default to MDSI under the materials recovery facility contract and gave MDSI 30 days to cure the default.  MDSI provided information that it believed demonstrated that it was not in default under the contract and had not withheld profits that it was obligated to deliver to the County under the terms of the contract.

On February 7, 2012, the County issued a Notice of Termination to MDSI terminating all of its contracts effective November 1, 2012.  The lawsuit followed on March 5, 2012.  MDSI answered the complaint and asserted a claim against the County for wrongful termination of the contracts. On October 31, 2012, MDSI ceased providing services and vacated the County premises.  The case is set for trial in Fresno in June 2014.

At this point, the Company is not able to determine the likelihood of any outcome in this matter.  The Company disputes Madera County’s right to terminate the MDSI contracts effective November 1, 2012, and seeks damages for the profits lost as a result of the wrongful termination.  The Company estimates that the current annual impact to its pre-tax earnings resulting from the termination of MDSI’s contracts with Madera County is approximately $2,300 per year, not including any monetary damages and interest the Court could order MDSI to pay the County.

Collective Bargaining Agreements 

Seven of the Company’s collective bargaining agreements have expired or are set to expire in 2014.  The Company does not expect any significant disruption in its overall business in 2014 as a result of labor negotiations, employee strikes or organizational efforts.

Revolver under Credit Facility

The Company has a senior revolving credit facility with a syndicate of banks for which Bank of America, N.A. acts as administrative agent.  The maximum borrowings available under the Company’s credit facility were $1,200,000 as of December 31, 2013 and 2012.  The Company has the ability to increase commitments under the revolving credit facility from $1,200,000 to $1,500,000, subject to conditions including that no default, as defined in the credit agreement, has occurred, although no existing lender has any obligation to increase its commitment.  Swing line loans may be issued at the request of the Company in an aggregate amount not to exceed a $25,000 sublimit and there is no maximum amount of standby letters of credit that can be issued under the credit facility; however, the issuance of swing line loans and standby letters of credit both reduce the amount of total borrowings available.  As of December 31, 2013, $727,100 was outstanding under the credit facility, exclusive of outstanding standby letters of credit of $75,166.  As of December 31, 2012, $787,000 was outstanding under the credit facility, exclusive of outstanding standby letters of credit of $87,252.  The credit facility matures in May 2018.  The Company has $4,722 of debt issuance costs recorded in Other assets, net in the Consolidated Balance Sheets at December 31, 2013 which are being amortized through the maturity date, or May 2018.

The borrowings under the credit facility bear interest, at the Company’s option, at either the base rate plus the applicable base rate margin (approximately 3.75% and 3.53% at December 31, 2013 and 2012, respectively) on base rate loans and swing line loans, or the LIBOR rate plus the applicable LIBOR margin (approximately 1.67% and1.48% at December 31, 2013 and 2012, respectively) on LIBOR loans.  The applicable margins under the credit facility vary depending on the Company’s leverage ratio, as defined in the credit agreement.  As of December 31, 2013 and 2012, the margins were 1.50% and1.28%, respectively, for LIBOR loans and 0.50% and 0.28%, respectively, for base rate loans and swing line loans.  As of December 31, 2013 and 2012, all outstanding borrowings under the credit facility were in LIBOR loans and swing line loans.

The credit facility requires the Company to pay an annual commitment fee on the unused portion of the facility.  The commitment fee was 0.23% as of each of December 31, 2013 and 2012. 

The borrowings under the credit facility are not collateralized.  The credit agreement contains representations, warranties, covenants and events of default, including a change of control event of default and limitations on incurrence of indebtedness and liens, new lines of business, mergers, transactions with affiliates and restrictive payments.  During the continuance of an event of default, the lenders may take a number of actions, including declaring the entire amount then outstanding under the credit agreement due and payable.  The credit facility contains cross-defaults if the Company defaults on the term loan facility, the Master Note Purchase Agreement or certain other debt.  The credit facility requires that the Company maintain specified quarterly leverage and interest coverage ratios.  The required leverage ratio cannot exceed 3.50x total debt to earnings before interest, taxes, depreciation and amortization, or EBITDA.  The required interest coverage ratio must be at least 2.75x total interest expense to earnings before interest and taxes, or EBIT.  As of December 31, 2013 and 2012, the Company’s leverage ratio was 3.08x and 3.28x, respectively.  As of December 31, 2013 and 2012, the Company’s interest coverage ratio was 6.33x and 6.88x, respectively.

Term Loan Facility

On October 25, 2012, the Company entered into a term loan facility in the original principal amount of $800,000 with Bank of America, N.A. and the other banks and lending institutions party thereto, as lenders, Bank of America, N.A., as administrative agent, and JPMorgan Chase Bank, N.A. and Wells Fargo Bank, National Association, as co-syndication agents.  The term loan is subject to principal payments which commenced at $10,000 per quarter in April 2013, increase to $20,000 per quarter in April 2014 and increase again to $30,000 per quarter in April 2015. A final principal payment of $390,000 is due upon maturity of the term loan facility on October 25, 2017. The Borrowings under the term loan facility were required to be used only to fund the R360 acquisition pursuant to the R360 purchase and sale agreement and to pay fees and expenses incurred in connection with the R360 acquisition and the Company’s entry into the term loan facility.  The Company is amortizing the $7,245 debt issuance costs through the maturity date, or October 2017.

Outstanding amounts on the term loan facility can be either base rate loans or LIBOR loans.  At December 31, 2013 and 2012, all amounts outstanding under the term loan facility were in LIBOR loans which bear interest at the LIBOR rate plus the applicable LIBOR margin (approximately 2.04% and2.21% at December 31, 2013 and 2012, respectively).  The LIBOR rate is determined by the administrative agent in a customary manner as described in the term loan agreement.  The applicable margins under the term loan agreement vary depending on the Company’s leverage ratio, as defined in the term loan agreement, as amended, and range from 1.375% per annum to 2.375% per annum for LIBOR loans.  As of December 31, 2013 and 2012, the margin was 1.875% and 2.0%, respectively, for LIBOR loans.  Borrowings under the term loan facility are not collateralized.

The term loan facility contains representations and warranties and places certain business, financial and operating restrictions on the Company relating to, among other things, indebtedness, liens, investments, mergers, consolidation and disposition of assets, sale and leaseback transactions, restricted payments and redemptions, burdensome agreements, business activities, transactions with affiliates, prepayments of indebtedness and accounting changes.  During the continuance of an event of default, the lenders may take a number of actions, including declaring the entire amount then outstanding under the term loan facility due and payable.  The term loan facility contains cross-defaults if the Company defaults on the senior revolving credit facility, the Master Note Purchase Agreement or certain other debt.  The term loan facility requires that the Company maintain specified quarterly leverage and interest coverage ratios.  The required leverage ratio cannot exceed 3.50x total debt to EBITDA.  The required interest coverage ratio must be at least 2.75x total interest expense to EBIT.  As of December 31, 2013 and 2012, the Company’s leverage ratio was 3.08x and 3.28x, respectively.  As of December 31, 2013 and 2012, the Company’s interest coverage ratio was 6.33x and 6.88x, respectively.

Master Note Purchase Agreement

Senior Notes due 2015

On July 15, 2008, the Company entered into a Master Note Purchase Agreement with certain accredited institutional investors pursuant to which the Company issued and sold to the investors at a closing on October 1, 2008, $175,000 of senior uncollateralized notes due October 1, 2015 in a private placement.  The 2015 Notes bear interest at the fixed rate of 6.22% per annum with interest payable in arrears semi-annually on April 1 and October 1 beginning on April 1, 2009, and with principal payable at the maturity of the 2015 Notes on October 1, 2015.  The Company is amortizing the $1,026 debt issuance costs over a seven-year term through the maturity date, or October 1, 2015.  

Senior Notes due 2019 

On October 26, 2009, the Company entered into a First Supplement to the Master Note Purchase Agreement with certain accredited institutional investors pursuant to which the Company issued and sold to the investors on that date $175,000 of senior uncollateralized notes due November 1, 2019 in a private placement.  The 2019 Notes bear interest at the fixed rate of 5.25% per annum with interest payable in arrears semi-annually on May 1 and November 1 beginning on May 1, 2010, and with principal payable at the maturity of the 2019 Notes on November 1, 2019.  The Company is amortizing the $152 debt issuance costs over a 10-year term through the maturity date, or November 1, 2019. 

Senior Notes due 2016, 2018 and 2021 

On April 1, 2011, the Company entered into a Second Supplement to the Master Note Purchase Agreement with certain accredited institutional investors, pursuant to which the Company issued and sold to the investors on that date $250,000 of senior uncollateralized notes at fixed interest rates with interest payable in arrears semi-annually on October 1 and April 1 beginning on October 1, 2011 in a private placement.  Of these notes, $100,000 will mature on April 1, 2016 with an annual interest rate of 3.30% (the “2016 Notes”), $50,000 will mature on April 1, 2018 with an annual interest rate of 4.00% (the “2018 Notes”), and $100,000 will mature on April 1, 2021 with an annual interest rate of 4.64% (the “2021 Notes”).  The Company is amortizing the $1,489 debt issuance costs through the maturity dates of the respective notes. 

The 2015 Notes, 2016 Notes, 2018 Notes, 2019 Notes, and 2021 Notes (collectively, the “Senior Notes”) are uncollateralized obligations and rank equally in right of payment with each of the Senior Notes, the obligations under the Company’s senior uncollateralized revolving credit facility and the obligations under the Company’s term loan facility.  The Senior Notes are subject to representations, warranties, covenants and events of default.  The Master Note Purchase Agreement contains cross-defaults if the Company defaults on the credit facility, the term loan facility or certain other debt. The Master Note Purchase Agreement requires that the Company maintain specified quarterly leverage and interest coverage ratios.  The required leverage ratio cannot exceed 3.75x total debt to EBITDA.  The required interest coverage ratio must be at least 2.75x total interest expense to EBIT.  As of December 31, 2013 and 2012, the Company’s leverage ratio was 3.08x and 3.28x, respectively.  As of December 31, 2013 and 2012, the Company’s interest coverage ratio was 6.33x and 6.88x, respectively. 

Upon the occurrence of an event of default, payment of the Senior Notes may be accelerated by the holders of the respective notes.  The Senior Notes may also be prepaid at any time in whole or from time to time in any part (not less than 5% of the then-outstanding principal amount) by the Company at par plus a make-whole amount determined in respect of the remaining scheduled interest payments on the Senior Notes, using a discount rate of the then current market standard for United States treasury bills plus 0.50%.  In addition, the Company will be required to offer to prepay the Senior Notes upon certain changes in control.

The Company may issue additional series of senior uncollateralized notes, including floating rate notes, pursuant to the terms and conditions of the Master Note Purchase Agreement, as amended, provided that the purchasers of the Senior Notes shall not have any obligation to purchase any additional notes issued pursuant to the Master Note Purchase Agreement and the aggregate principal amount of the outstanding notes and any additional notes issued pursuant to the Master Note Purchase Agreement shall not exceed $1,250,000.

				$	33,030	$	35,655	$	33,654

In August 2013, the Company gave notice to redeem its LeMay Olympia Bond with a remaining principal balance of $2,120.  The Company paid in full the principal and accrued interest on this bond on October 2, 2013.

In October 2013, the Company gave notice to redeem its Tehama Bond with a remaining principal balance of $205.  The Company paid in full the principal and accrued interest on this bond on January 8, 2014.

The variable-rate bonds are all remarketed weekly by a remarketing agent to effectively maintain a variable yield.  If the remarketing agent is unable to remarket the bonds, then the remarketing agent can put the bonds to the Company.  The Company has obtained standby letters of credit, issued under its senior revolving credit facility, to guarantee repayment of the bonds in this event.  The Company classified these borrowings as long-term at December 31, 2013, because the borrowings are supported by standby letters of credit issued under the Company’s senior revolving credit facility which matures in May 2018. 

As of December 31, 2013, aggregate contractual future principal payments by calendar year on long-term debt are due as follows: 

2014	$	5,385
2015		259,084

Fair Value of Financial Instruments

8.FAIR VALUE OF FINANCIAL INSTRUMENTS 

The Company uses a three-tier fair value hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis, as well as assets and liabilities measured at fair value on a non-recurring basis, in periods subsequent to their initial measurement.  These tiers include:  Level 1, defined as quoted market prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, model-based valuation techniques for which all significant assumptions are observable in the market, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and Level 3, defined as unobservable inputs that are not corroborated by market data. 

The Company’s financial assets and liabilities recorded at fair value on a recurring basis include derivative instruments and restricted assets.  The Company’s derivative instruments are pay-fixed, receive-variable interest rate swaps and a pay-fixed, receive-variable diesel fuel hedge.  The Company’s interest rate swaps are recorded at their estimated fair values based on quotes received from financial institutions that trade these contracts.  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.  The Company uses a discounted cash flow (“DCF”) model to determine the estimated fair value of the diesel fuel hedge.  The assumptions used in preparing the DCF model include: (i) estimates for the forward DOE index curve; and (ii) the discount rate based on risk-free interest rates over the term of the hedge contract.  The DOE index curve used in the DCF model was obtained from financial institutions that trade these contracts and ranged from $3.79 to $4.00 at December 31, 2013 and from $3.68 to $3.87 at December 31, 2012.  The weighted average DOE index curve used in the DCF model was $3.91 and $3.77 at December 31, 2013 and 2012, respectively.  Significant increases (decreases) in the forward DOE index curve would result in a significantly higher (lower) fair value measurement.  For the Company’s interest rate swaps and fuel hedge, the Company also considers the Company’s creditworthiness in its determination of the fair value measurement of these instruments in a net liability position and the banks’ creditworthiness in its determination of the fair value measurement of these instruments in a net asset position.  The Company’s restricted assets 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 assets measured at fair value are invested primarily in U.S. government and agency securities. 

The Company’s assets and liabilities measured at fair value on a recurring basis at December 31, 2013 and 2012, were as follows: 

	Fair Value Measurement at December 31, 2013 Using
	Total		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

Use of Estimates and Assumptions [Abstract]

Use of Estimates and Assumptions

2.USE OF ESTIMATES AND ASSUMPTIONS 

In preparing the Company’s consolidated financial statements, several estimates and assumptions are made that affect the accounting for and recognition of assets, liabilities, revenues and expenses.  These estimates and assumptions must be made because certain of the information that is used in the preparation of the Company’s consolidated financial statements is dependent on future events, cannot be calculated with a high degree of precision from data available or is simply not capable of being readily calculated based on generally accepted methodologies.  In some cases, these estimates are particularly difficult to determine and the Company must exercise significant judgment.  The most difficult, subjective and complex estimates and the assumptions that deal with the greatest amount of uncertainty are related to the Company’s accounting for landfills, self-insurance accruals, income taxes, allocation of acquisition purchase price and asset impairments, which are discussed in Note 1.  An additional area that involves estimation is when the Company estimates the amount of potential exposure it may have with respect to litigation, claims and assessments in accordance with the accounting guidance on contingencies.  Actual results for all estimates could differ materially from the estimates and assumptions that the Company uses in the preparation of its consolidated financial statements.

Stockholders' Equity [Abstract]

Stockholders' Equity

12.STOCKHOLDERS' EQUITY 

Sale of Common Stock

On February 27, 2012, the Company entered into an underwriting agreement with Morgan Stanley & Co. LLC, in connection with the offer and sale by the Company of 12,000,000 shares of its common stock, par value $0.01 per share.  The shares of common stock were sold to Morgan Stanley & Co. LLC at a price of $30.83 per share.  The offering closed on March 2, 2012.  The Company received net proceeds from this offering of $369,584 after deducting transaction expenses paid by the Company of approximately $376.  

Cash Dividend

The Company’s Board of Directors authorized the initiation of a quarterly cash dividend in October 2010 and has increased it on an annual basis.  In October 2013, the Company announced that its Board of Directors increased its regular quarterly cash dividend by $0.015, from $0.10 to $0.115 per share.  Cash dividends of $51,213,  $44,465 and $35,566 were paid during the years ended December 31, 2013, 2012 and 2011, respectively. 

Share Repurchase Program 

The Company’s Board of Directors has authorized a common stock repurchase program for the repurchase of up to $1,200,000 of common stock through December 31, 2014.  Under the program, stock repurchases may be made in the open market or in privately negotiated transactions from time to time at management's discretion.  The timing and amounts of any repurchases will depend on many factors, including the Company's capital structure, the market price of the common stock and overall market conditions.  As of December 31, 2012, the Company had repurchased in aggregate 39,865,266 shares of its common stock at an aggregate cost of $784,040.  The Company did not repurchase any shares of its common stock during the year ended December 31, 2013.  As of December 31, 2013, the remaining maximum dollar value of shares available for repurchase under the program was approximately $415,960.  The Company’s policy related to repurchases of its common stock is to charge any excess of cost over par value entirely to additional paid-in capital.

Of the 126,433,513 shares of common stock authorized but unissued as of December 31, 2013, the following shares were reserved for issuance:

Restricted Stock, Stock Options and Restricted Stock Units 

 In 2004, the Company’s Board of Directors authorized the 2004 Equity Incentive Plan. On May 7, 2010, the Company’s stockholders approved the latest amendment to the plan, now the Third Amended and Restated 2004 Equity Incentive Plan (the “2004 Equity Incentive Plan”).  A total of 7,162,500shares of the Company’s common stock were reserved for future issuance under the 2004 Equity Incentive Plan, all of which may be used for grants of stock options, restricted stock, and/or restricted stock units.  Participation in the 2004 Equity Incentive Plan is limited to employees, officers, directors and consultants.  Options granted under the 2004 Equity Incentive Plan are nonqualified stock options and have a term of no longer than five years from the date they are granted.  Restricted stock, restricted stock units, and options generally vest in installments pursuant to a vesting schedule set forth in each option or restricted stock or unit agreement.  The Board of Directors authorizes the granting of options, restricted stock and restricted stock units, and determines the employees and consultants to whom options, restricted stock, and restricted stock units are to be granted, the number of shares subject to each option, restricted stock, or restricted stock unit, the exercise price, term, vesting schedule and other terms and conditions of the options, restricted stock, or restricted stock units.  The exercise prices of the options shall not be less than the fair market value of the Company’s common stock on the date of grant.  Restricted stock awards under the plan may or may not require a cash payment from a participant to whom an award is made; restricted stock unit awards under the plan do not require any cash payment from the participant to whom an award is made.  The fair value of restricted stock units granted during the years ended December 31, 2013, 2012 and 2011, was determined based on the number of restricted stock units granted and the quoted price of the Company’s common stock on the date of grant.  As of December 31, 2013,  1,046,592 shares of common stock were available to be issued pursuant to future awards granted under the 2004 Equity Incentive Plan.
