Basis of Presentation

The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("US GAAP") for interim financial information and with the Securities and Exchange Commission's ("SEC") instructions to Form 10-Q.  Accordingly, they do not include all of the information and notes required by US GAAP for complete financial statements.  In the opinion of management, all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation of financial position, results of operations and cash flows have been included.

The results of operations for the interim periods shown in this report are not necessarily indicative of the results to be expected for the full year.  The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company's Annual Report on Form 10-K for the fiscal year ended April 30, 2012 filed with the SEC on July 6, 2012.  The condensed consolidated balance sheet as of April 30, 2012 has been derived from the audited financial statements included in the Form 10-K for that year.
