19. Commitments and Contingencies

Self-Insurance

The Company is self-insured for certain losses, liabilities and employee benefit costs, subject to a stop loss policy or deductible limits. Liabilities associated with the risks that are retained by the Company are estimated, in part, by considering an analysis of actual claims, historical claims experience, demographic factors and other actuarial assumptions. While the Company believes that its assumptions are appropriate, the estimated accrual for these liabilities could be significantly affected if future occurrences and claims materially differ from these assumptions and historical trends.

Legal Proceedings

The Company is periodically involved in various legal proceedings that are incidental to the conduct of its business, including but not limited to labor and employment-related claims, customer injury claims, investigations and other proceedings arising in the ordinary course of business. When the potential liability from a matter can be estimated and the loss is considered probable, the Company records the estimated loss. Due to uncertainties related to the resolution of lawsuits, investigations, and claims, the ultimate outcome may differ from the estimates. Although the Company cannot predict with certainty the ultimate resolution of any lawsuits, investigations, and claims asserted against it, management does not believe any currently pending legal proceeding to which the Company is a party will have a material adverse effect on its financial statements.
