1.   The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q of Regulation S-X and do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements.  Therefore, these financial statements should be read in conjunction with the annual report on Form 10-K dated April 30, 2011.  In our opinion, all adjustments (consisting of normal recurring accruals) necessary for a fair presentation have been included.  Operating results for the three and six months ended October 31, 2011 are not indicative of the results of operations that may be expected for the year ended April 30, 2012.

Certain reclassifications within the condensed financial statement captions have been made to maintain consistency in presentation between years.
