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 19% of our liabilities at December 31, 2013. 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 is affected by various uncertainties because we must make assumptions and apply judgment to estimate the ultimate cost to settle reported claims and claims incurred but not reported as of the balance sheet date. We address these uncertainties by regularly evaluating our claims’ pay-out experience, present value factor and other factors related to the nature of specific claims in arriving at the basis for our accrued insurance claims estimate. Our evaluations are based primarily on current information derived from reviewing our claims experience and industry trends. In the event that our claims experience and/or industry trends result in an unfavorable change resulting from, among other factors, the severity levels of reported claims and medical cost inflation, as compared to historical claim trends, it would have an adverse effect on our results of operations and financial condition. Under these plans, predetermined loss limits are arranged with an insurance company to limit both our per-occurrence cash outlay and annual insurance plan cost. For workers’ compensation, we record a reserve based on the present value of estimated future cost of claims and related expenses that have been reported but not settled, including an estimate of claims incurred but not reported that are developed as a result of a review of our historical data and open claims. The present value of the payout is determined by applying an 8% discount factor against the estimated value of the claims over the estimated remaining pay-out period. Reducing the discount factor by 1% would reduce net income for the year ended December 31, 2013 by approximately $34,000. Additionally, reducing the estimated payout period by six months would result in an approximate $84,000 reduction in net income. For general liability, we record a reserve for the estimated ultimate amounts to be paid for known claims and claims incurred but not reported as of the balance sheet date. The estimated ultimate reserve amount recorded is derived from the estimated claim reserves provided by our insurance carrier reduced by an historical experience factor.

We currently have a Paid Loss Retrospective Insurance Plan for general liability and workers’ compensation insurance, which comprise approximately 19% of our liabilities at December 31, 2013.
