(1) Insurance obligations are primarily comprised of self-insured claim liabilities.

(2) The decrease in restructuring liabilities from December 31, 2017, principally represents a reduction in the accrual for employee termination costs. The majority of the balance remaining in restructuring liabilities is expected to be paid by the end of 2019.
