Reclassifications—Certain items have been reclassified within operating expenses for the three and nine months ended October 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 due to the significance in variability of timing and amount. 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.

The amounts have been reclassified in our condensed consolidated statements of operations for the time periods noted below as follows:
