All significant intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, these condensed consolidated interim financial statements reflect all adjustments that are of a normal recurring nature and which are necessary to present fairly our consolidated financial position as of June 30, 2018 and September 30, 2017, our consolidated results of operations and consolidated comprehensive income for the three and nine months ended June 30, 2018 and 2017, and our consolidated cash flows for the nine months ended June 30, 2018 and 2017.

Each quarter, management evaluates, based on relevant conditions and events, our ability to continue as a going concern for at least one year from the date our financial statements are issued. Based on management’s assessment, we have concluded that there does not exist substantial doubt about our ability to continue as a going concern as of the date the condensed consolidated interim financial statements included herein were issued. Certain amounts for the prior fiscal periods have been reclassified to conform to the current fiscal period presentation, in connection with the retroactive adoption of two new accounting pronouncements in the current fiscal year.
