Commitments and Contingencies | Commitments and Contingencies Financial Instruments The Company has obtained letters of credit, performance bonds and insurance policies for the performance of landfill final capping, closure and post-closure requirements, environmental remediation, and other obligations. Letters of credit are supported by the Company’s Revolver (Note 5). The Company does not expect that any claims against or draws on these instruments would have a material adverse effect on the Company’s condensed consolidated financial statements. The Company has not experienced any unmanageable difficulty in obtaining the required financial assurance instruments for its current operations. In an ongoing effort to mitigate risks of future cost increases and reductions in available capacity, the Company continues to evaluate various options to access cost-effective sources of financial assurance. Insurance The Company carries insurance coverage for protection of its assets and operations from certain risks including automobile liability, general liability, real and personal property, workers' compensation, directors and officers liability, pollution, legal liability and other coverages the Company believes are customary to the industry. The Company's exposure to loss for insurance claims is generally limited to the per incident deductible, or self-insured retention, under the related insurance policy. Its exposure, however, could increase if its insurers are unable to meet their commitments on a timely basis. The Company has retained a significant portion of the risks related to its automobile, general liability, workers' compensation and health claims programs. For its self-insured retentions, the exposure for unpaid claims and associated expenses, including incurred but not reported losses, is based on an actuarial valuation and internal estimates. The accruals for these liabilities could be revised if future occurrences or loss development significantly differ from the Company's assumptions used. The Company does not expect the impact of any known casualty, property, environmental or other contingency to have a material impact on its financial condition, results of operations or cash flows. Litigation and Other Matters In February 2009, the Company and certain of its subsidiaries were named as defendants in a purported class action suit in the Circuit Court of Macon County, Alabama. Similar class action complaints were brought against the Company and certain of its subsidiaries in 2011 in Duval County, Florida and in 2013 in Quitman County, Georgia and Barbour County, Alabama, and in 2014 in Chester County, Pennsylvania. The 2013 Georgia complaint was dismissed in March 2014. In late 2015 in Gwinnett County, Georgia, another purported class action suit was filed. The plaintiffs in those cases primarily allege that the defendants charged improper fees (fuel, administrative and environmental fees) that were in breach of the plaintiffs' service agreements with the Company and seek damages in an unspecified amount. The Company believes that it has meritorious defenses against these purported class actions, which it will vigorously pursue. Given the inherent uncertainties of litigation, including the early stage of these cases, the unknown size of any potential class, and legal and factual issues in dispute, the outcome of these cases cannot be predicted and a range of loss, if any, cannot currently be estimated. In November 2014, the Attorney General of the State of Vermont filed a complaint against the Company relating to the Moretown, Vermont landfill regarding alleged odor and other environmental-related noncompliances with environmental laws and regulations and environmental permits. In the complaint, the Attorney General requested that the State of Vermont Superior Court find the Company liable for the alleged noncompliances, issue related civil penalties, and order the Company to reimburse the State of Vermont for enforcement costs. While the complaint does not specify a monetary penalty, prior correspondence from the Attorney General of the State of Vermont indicates that it may seek a penalty relating to the alleged noncompliances that is not expected to be material. Given the inherent uncertainties of litigation, including the early stage of this case, the outcome cannot be predicted and a range of loss, if any, cannot currently be estimated. In February 2017, a waste slide occurred in one cell at the Company’s Greentree Landfill in Kersey, Pennsylvania. During the six months ended June 30, 2017 , the Company recorded a charge in operating expenses of $5.4 , representing the Company’s current estimate of probable costs to relocate displaced material and restore infrastructure, net of estimated insurance recoveries; this amount could increase or decrease as a result of actual costs incurred to completion and insurance recoveries. The Company has incurred $2.4 and $3.9 for the three and six months ended June 30, 2017 , respectively. The Company is subject to various other proceedings, lawsuits, disputes and claims and regulatory investigations arising in the ordinary course of its business. Many of these actions raise complex factual and legal issues and are subject to uncertainties. Actions filed against the Company include commercial, customer, and employment-related claims. The plaintiffs in some actions seek unspecified damages or injunctive relief, or both. These actions are in various procedural stages, and some are covered in part by insurance. Although the Company cannot predict the ultimate outcome and the range of loss cannot be currently estimated, the Company does not believe that the eventual outcome of any such action could have a material adverse effect on its business, financial condition, results of operations, or cash flows. Multiemployer Defined Benefit Pension Plans Approximately 12.7% of the Company’s workforce is covered by collective bargaining agreements with various local unions across its operating regions. As a result of some of these agreements, certain of the Company’s subsidiaries are participating employers in a number of trustee-managed multiemployer, defined benefit pension plans for the affected employees. In connection with its ongoing renegotiation of various collective bargaining agreements, the Company may discuss and negotiate for the complete or partial withdrawal from one or more of these pension plans. A complete or partial withdrawal from a multiemployer pension plan may also occur if employees covered by a collective bargaining agreement vote to decertify a union from continuing to represent them. The Company is not aware of any such actions in connection with continuing operations. As a result of certain discontinued operations, the Company is potentially exposed to certain withdrawal liabilities. The Company does not believe that any future withdrawals, individually or in the aggregate, from the multiemployer plans to which it contributes could have a material adverse effect on the Company's business, financial condition or liquidity. However, such withdrawals could have a material adverse effect on the Company's results of operations for a particular reporting period, depending on the number of employees withdrawn in any future period and the financial condition of the multiemployer plan(s) at the time of such withdrawal(s). Tax Matters The Company has open tax years dating back to 2000 in certain jurisdictions. Prior to the acquisition, MW Star Holdings, Corp. (Veolia ES Solid Waste division) was part of a consolidated group and is still subject to IRS and state examinations dating back to 2004. Pursuant to the terms of the acquisition of Veolia ES Solid Waste, Inc., the Company is entitled to certain indemnifications for Veolia ES Solid Waste Division's pre-acquisition tax liabilities. The Company maintains a liability for uncertain tax positions, the balance of which management believes is adequate. Results of audit assessments by taxing authorities are not currently expected to have a material adverse impact on the Company's results of operations or cash flows. |
