Accrued expenses for insurance are primarily for general liability, workers’ compensation and employee healthcare policies for which the Company is self-insured up to certain per-occurrence and aggregate limits. The amounts accrued represent the Company's best estimates of the probable amount of claims to be paid. Differences between the amounts accrued and the amount that may be reasonably possible of payment are not material. Accrued expenses for unearned revenue primarily relate to up-front customer deposits received on contracts for goods and services to be provided by the Company as further discussed in Note 3 "Revenue". The current portion of share-based liabilities represents the Company's equity-based awards that are settled in cash, further described in Note 12 "Equity-Based Compensation".
