The accompanying condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to such rules and regulations.

In the opinion of management, the accompanying condensed consolidated financial statements contain all adjustments (including normal recurring accruals) necessary to present fairly the financial position as of January 31, 2017 and April 30, 2016, and the results of operations for the three and nine months ended January 31, 2017 and 2016, and cash flows for the nine months ended January 31, 2017 and 2016. Although management believes that the disclosures are adequate to make the information presented not misleading, it is suggested that these interim condensed consolidated financial statements be read in conjunction with the Company’s most recent audited financial statements and notes thereto.
