Retirement 401(k) Plan

To help employees supplement their retirement income, the voluntary Retirement 401(k) Plan through Charles Schwab permits eligible employees to defer up to 100% of their compensation on a pre-tax basis, and/or up to 100% of their post-tax compensation, to a savings plan as allowed by Section 401(k) of the IRS Code. Contributions to the Retirement 401(k) Plan are subject to IRS annual guidelines/limits and as defined in the Plan.

The Retirement 401(k) Plan has a variety of investment options to which employees can choose to direct their contributions. Additionally, Mott MacDonald may make discretionary “bonus contributions” and discretionary match contributions to eligible employees.

The Company reserves the right to vary the plan rules at any time, subject to IRS rules and regulations.
