All full-time, part-time and temporary employees are immediately eligible for the RSP upon hire and will have an opportunity to enroll within one week of hire date. You may contribute up to 75% of eligible compensation (subject to IRS limitations). Contribution options include pre-tax, Roth 401(k) and after-tax, with an option for in-plan Roth conversions. Automatic enrollment at 1% occurs 45 days after your hire date.
AECOM matches 50% of the first 6% of pre-tax or Roth 401(k) contributions. After-tax contributions are not matched. Matching contributions are credited each April for the prior calendar year, with 50% allocated to the AECOM Stock Fund and the remaining 50% per your investment elections. To be eligible for matching contributions, you must be an employee on the last day of the year, some exceptions apply. Your contributions are always vested. Matching contributions vest gradually over three years based on your eligible years of service.
