Profit Sharing and Retirement Plans
Nasdaq continues to provide both tax-qualified and a non-qualified savings and retirement plans. All eligible employees may participate in the tax qualified plans (both pension and savings). Participation by Nasdaq employees in the defined contribution tax-qualified 401(k) savings plan is approximately 96%. Nasdaq matches up to 4% of an employees eligible compensation to this plan during the year and may make an additional discretionary contribution to the plan as approved by the Nasdaq Board on the Committees recommendation, which may vary with the financial performance of Nasdaq. No additional discretionary match was made for 2004.
Nasdaq continues as a participating employer along with the NASD in the NASD Pension Plan. See Pension Plan Table for a description of the benefits under the Pension Plan and SERP, including the amendments discussed above.
