7.  Segment Information

Prior to the quarter ended February 29, 2012, we operated in two segments. PDSG was reflected as a separate reporting unit. With our board of directors authorization to sell the assets of PDSG, we have classified PDSG as discontinued operations (see Note 1).  As a result, we now operate in one segment.
