AROs reflect management’s best estimates of expected future costs to restore current leased premises to their original condition prior to lease inception. Cash outflows associated with our ARO liabilities are generally expected to occur at the restoration dates of the assets to which they relate, which are long-term in nature. The timing and extent of restoration work that will be ultimately required for these sites is uncertain.
