Self-Insurance

The Company obtains various insurance coverages, including general and professional liability and workers compensation programs, from commercial carriers at stated amounts as defined in the applicable policy. Losses related to deductible amounts are accrued based on the Company's estimate of expected losses plus incurred but not reported claims.

As of December 31, 2019 and 2018, the Company accrued reserves of $155.8 million and $155.6 million, respectively, for these programs, of which $92.5 million and $94.5 million is classified as long-term liabilities as of December 31, 2019 and 2018, respectively. As of December 31, 2019 and 2018, the Company accrued $22.7 million and $13.1 million, respectively, of estimated amounts receivable from the insurance companies under these insurance programs. During the years ended December 31, 2019, 2018, and 2017, the Company reduced its estimate of the amount of accrued liabilities for these programs based on recent claims experience. The reduction in these accrued reserves decreased operating expenses by $11.3 million, $14.6 million, and $9.9 million, for the years ended December 31, 2019, 2018, and 2017, respectively.

The Company has secured self-insured retention risk under workers' compensation programs with restricted cash deposits of $24.0 million and $14.7 million as of December 31, 2019 and 2018, respectively. Letters of credit securing the programs aggregated to $55.6 million and $71.8 million as of December 31, 2019 and 2018, respectively. In addition, the Company also had deposits of $12.3 million and $13.7 million, as of December 31, 2019 and 2018, respectively, to fund claims paid under a high deductible, collateralized insurance policy.
