Reclassifications and Revisions to Prior Period Financial Statements	Reclassifications and Revisions to Prior Period Financial Statements In the third quarter of fiscal year 2012, we identified certain amounts totaling $620 recorded within “Effect of exchange rate changes on cash” in our unaudited condensed consolidated statements of cash flows for the first two quarters of fiscal year 2012 that should be classified primarily within cash flow from operating activities. We determined that this error in classification was not material to our unaudited condensed consolidated statement of cash flows for each quarter in fiscal year 2012. We have corrected this error by revising the unaudited condensed consolidated cash flow statement for the six months ended January 31, 2012. The unaudited condensed consolidated statement of cash flows for the six months ended January 31, 2012 reflects increases in “Effect Of Exchange Rate Changes On Cash” and “Net Cash Used For Financing Activities” of $620 and $34, respectively, with a corresponding decrease in the “Net Cash Provided by Operating Activities” of $654.
