During the current quarter, the Company revised its condensed consolidated statement of cash flow for the three months ended September 30, 2017 to correctly present the changes in accounts payable and accrued liabilities and in purchases of property, plant and equipment, resulting in an increase of $19.8 million to previously reported net cash flow used for operating activities and a corresponding decrease to previously reported net cash flow used for investing activities. Revisions of $25.7 million and $22.7 million will be made in future filings to the condensed consolidated statements of cash flow for the six months ended December 31, 2017 and the nine months ended March 31, 2018, respectively, with similar effects on the condensed consolidated statements of cash flow. The supplemental disclosure of non-cash information for changes in accounts payable related to purchases of property, plant and equipment for the three months ended September 30, 2017 was also revised accordingly, at an increase of $8.3 million. The amount of that disclosure will be revised in future filings for the six months ended December 31, 2017 and the nine months ended March 31, 2018 to depict increases of $14.2 million and $11.2 million, respectively. The Company has evaluated the correction and determined it was not material to the previously issued interim financial statements. The correction had no effect on the previously issued annual financial statements.
