Special charges generally include expenses incurred related to employee severance, certain litigation costs, acquisitions, excess facility costs, and asset related charges.

We offered the voluntary early retirement program during the three months ended April 30, 2015. Approximately 110 employees in North America elected to participate. The costs presented here are for severance benefits. Approximately 82% of these costs were paid during the period. We expect to pay the remainder during the fiscal year ending January 31, 2016.

Employee severance and related costs include severance benefits, notice pay, and outplacement services. These rebalance charges generally represent the aggregate of numerous unrelated rebalance plans which impact several employee groups, none of which is individually material to our financial position or results of operations. We determine termination benefit amounts based on employee status, years of service, and local statutory requirements. We record the charge for estimated severance benefits in the quarter that the rebalance plan is approved.

Approximately 16% of the employee severance and related costs for the three months ended April 30, 2015 were paid during the period. We expect to pay the remainder during the fiscal year ending January 31, 2016. Substantially all of the employee severance and related costs for the three months ended April 30, 2014 were paid during the fiscal year ending January 31, 2015. There were no significant modifications to the amount of those charges.

Litigation costs consist of professional service fees for services rendered, related to patent litigation involving us, EVE, and Synopsys regarding emulation technology.

Accrued special charges are included in accrued and other liabilities and other long-term liabilities in the condensed consolidated balance sheets. The following table shows changes in accrued special charges during the three months ended April 30, 2015:
