In December 2011, the FASB amended and updated the guidance issued in June 2011 to defer certain presentation requirements. The amended and updated guidance was effective for the Company for the interim period ended April 30, 2012 and has been applied retrospectively as required by this standard. Other than the change in presentation, adoption of this guidance did not impact the Company's condensed consolidated financial statements.
