(1) Insurance obligations primarily represent claims for which we are self-insured.

(2) The reduction in restructuring liabilities from December 31, 2015 principally represents cash payments for employee termination costs. The majority of the balance remaining in restructuring liabilities is expected to be paid by the end of 2016.
