Reclassifications—Certain items have been reclassified within operating expenses for the three months ended April 30, 2013 and 2012, and the three and six months ended July 31, 2012. We have reclassified certain litigation costs out of general and administration into special charges, related to patent litigation involving Emulation and Verification Engineering S.A. and EVE-USA, Inc (together, EVE), Synopsys, Inc. (Synopsys), and us regarding emulation technology. These litigation costs are included in special charges because of their unique nature. These reclassifications had no impact on total operating expenses, operating income, or net income. See further discussion of these lawsuits in Note 8. "Commitments and Contingencies."

The reclassification of our previously issued condensed consolidated statement of operations was made to conform to the current period presentation.
