A Summary of Benefits from MKS Instruments

The following is a brief summary of the benefits offered to you by MKS. It does not contain complete details on every plan. The actual terms and conditions of each program are defined with plan documents available for review in the Human Resources Department.

Retirement Income Plan:

401(k) Savings Plan:

All regular employees are eligible to participate in the 401(k) Plan after 30 days of employment. If you do not actively enroll within 30 days of hire, you will automatically be enrolled in the Plan at a contribution rate of 3%, which will be deducted from your second paycheck after the 30 day eligibility period ends. You may opt out of the Plan within the 30 day eligibility period and as soon as you receive your first paycheck by calling Fidelity. An employee may contribute 1-50% of earnings on a pretax basis, up to the IRS limit. MKS will match your contributions to the Plan up to 3% of your compensation. To take full advantage of the match you will need to contribute 6% of your compensation and MKS will match 50 cents on each dollar you contribute up to 3%. You are always vested in your own contributions and earnings. Vesting in the discretionary company match and Profit-Sharing Plan (if any) is after the completion of 1 year of service. We also offer a Roth 401(k). Both the Roth 401(k) and traditional 401(k) are subject to the annual IRS limits.
