Acquiring or constructing property, plant and equipment by incurring a liability does not result in a cash outflow for us until the liability is paid. In the period the liability is incurred, the change in operating accounts payable on the Consolidated Statements of Cash Flows is adjusted by such amount. In the period the liability is paid, the amount is reflected as a cash outflow from investing activities. The applicable net change in operating accounts payable that was classified to investing activities on the Consolidated Statements of Cash Flows was $(21.9) million and $29.3 million for 2015 and 2014, respectively, $87.7 million for the seven months ended December 31, 2013 and $54.6 million for fiscal 2013.

In September 2014, we accrued $120 million representing the remaining liability for our portion of mineral rights value transferred to MWSPC from Ma’aden. The offset to this liability was recorded as an investment in nonconsolidated companies. This amount is expected to be paid in 2016.

Depreciation, depletion and amortization includes $732.2 million related to depreciation and depletion of property, plant and equipment, and $7.6 million related to amortization of intangible assets for 2015.
