9. CONTINGENCIES

The Company carries insurance policies on insurable risks with coverage and other terms that it believes to be appropriate. The Company has self-insured retention limits and has obtained fully insured layers of coverage above such self-insured retention limits. Accruals for self-insurance losses are made based on claims experience. Liabilities for existing and unreported claims are accrued when it is probable that future costs will be incurred and can be reasonably estimated.

Environmental and Legal Matters

The Company accrues expenses for contingencies when it is probable that an asset has been impaired or a liability has been incurred and management can reasonably estimate the expense. Contingencies for which the Company has made accruals include environmental and other legal matters. It is possible, however, that actual expenses could exceed the accruals by a material amount, which could have a material adverse effect on the Company’s future liquidity, financial condition, and operating results in the period in which any such additional expenses are incurred or recognized.

Environmental Matters

The Company was previously identified as a potentially responsible party in connection with contamination cleanup at a formerly owned property in Montana. On February 18, 2015, the Montana Department of Environmental Quality (the “DEQ”) issued an amendment to the unilateral administrative order of the DEQ outlining the final remediation of the property in its Record of Decision. In September 2015, the remedial action work plan (“RAWP”) was approved.

The Company paid $0.1 million in the first three months of 2020 implementing the RAWP. The Company estimates the total remaining cost of implementing the RAWP to be $2.9 million at March 31, 2020 with $1.1 million in short-term other accrued liabilities and $1.8 million in other non-current liabilities. As of March 31, 2020, the Company believes the accrual represents a reasonable best estimate of the total remaining remediation costs, based on facts, circumstances, and information currently available.
