Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | Commitments and Contingencies In the ordinary course of conducting our business, we become involved in litigation and other claims from private party actions, as well as judicial and administrative proceedings involving governmental authorities at the federal, state, and local levels. While the outcome of litigation or other proceedings against us cannot be predicted with certainty, management does not expect that any loss resulting from such litigation or other proceedings, in excess of any amounts accrued or covered by insurance, will have a material adverse impact on our consolidated financial statements. Other We do not have any special purpose entities. At December 31, 2021, we had $45.3 million in outstanding letters of credit, performance bonds, and other guarantees for which certain of the letters of credit are collateralized by $5.4 million in restricted cash. We also enter into normal short-term operating leases for office and warehouse space, as well as rolling stock and other pieces of operating equipment. None of these off-balance sheet arrangements either had, or is expected to have, a material effect on our financial statements. We are self-insured for health claims, subject to certain “stop loss” insurance policies. Claims in excess of $250,000 per incident are insured by third-party insurers. Based on historical experience, we had accrued liabilities of $0.7 million for unpaid claims incurred at both December 31, 2021 and 2020. Substantially all of these estimated claims are expected to be paid within six months of their occurrence. In addition, we are self-insured for certain workers’ compensation, auto, and general liability claims up to a certain policy limit. Claims in excess of $750,000 are insured by third-party reinsurers. Based on historical experience, we had accrued liabilities of $2.5 million and $2.8 million for the uninsured portion of claims at December 31, 2021 and 2020, respectively. We also maintain accrued liabilities for asset retirement obligations, which represent obligations associated with the retirement of tangible long-lived assets that result from the normal operation of the long-lived asset. Our asset retirement obligations primarily relate to required expenditures associated with owned and leased facilities. Upon settlement of the liability, a gain or loss for any difference between the settlement amount and the liability recorded is recognized. We had accrued asset retirement obligations of $1.1 million and $1.2 million at December 31, 2021 and 2020, respectively.
