Payables and Accruals [Abstract]
Accrued Insurance Claims	Accrued Insurance Claims We currently have a Paid Loss Retrospective Insurance Plan for general liability and workers’ compensation insurance, which comprise approximately 46.2% of our liabilities at December 31, 2016. Under our insurance plans for general liability and workers’ compensation, predetermined loss limits are arranged with our insurance company to limit both our per occurrence cash outlay and annual insurance plan cost. Our accounting for this plan utilizes current valuations from a third party actuary, which include assumptions based on data such as historical claims, pay-out experience, demographic factors, industry trends, severity factors, and other actuarial calculations. In the event that our claims experience and/or industry trends result in an unfavorable change in our assumptions or outcomes, it would have an adverse effect on our results of operations and financial condition. For workers’ compensation and general liability, we record both a reserve for the estimated future cost of claims and related expenses that have been reported but not settled, as well as an estimate of claims incurred but not reported. Such reserves for claims incurred but not reported are developed by a third party actuary through review of our historical data and open claims.

We currently have a Paid Loss Retrospective Insurance Plan for general liability and workers’ compensation insurance, which comprise approximately 46.2% of our liabilities at December 31, 2016. Under our insurance plans for general liability and workers’ compensation, predetermined loss limits are arranged with our insurance company to limit both our per occurrence cash outlay and annual insurance plan cost. Our accounting for this plan utilizes current valuations from a third party actuary, which include assumptions based on data such as historical claims, pay-out experience, demographic factors, industry trends, severity factors, and other actuarial calculations. In the event that our claims experience and/or industry trends result in an unfavorable change in our assumptions or outcomes, it would have an adverse effect on our results of operations and financial condition.

For workers’ compensation and general liability, we record both a reserve for the estimated future cost of claims and related expenses that have been reported but not settled, as well as an estimate of claims incurred but not reported. Such reserves for claims incurred but not reported are developed by a third party actuary through review of our historical data and open claims.
