PENSION BENEFIT PLANS | PENSION BENEFIT PLANS 401(k) Plan The Company has a defined contribution program for certain employees that is qualified under Section 401(k) of the Internal Revenue Code of 1986, as amended. The Company matches 50% of the employee's contribution up to 6% of the employee’s salary. NetScout contributions vest at a rate of 25% per year of service. NetScout made matching contributions of $5.8 million, $7.0 million and $6.7 million to the plan for the fiscal years ended March 31, 2025, 2024 and 2023, respectively. Defined Benefit Pension Plan Certain of the Company's non-U.S. employees participate in certain noncontributory defined benefit pension plans. None of the Company's employees in the U.S. participate in any noncontributory defined benefit pension plans. In general, these plans are funded based on considerations relating to legal requirements, underlying asset returns, the plan's funded status, the anticipated deductibility of the contribution, local practices, market conditions, interest rates and other factors. The Company recognizes on its balance sheet a liability equal to the under-funded benefit obligation of its defined benefit pension plan.
