What Mantech International's 401(k) plan says about matching contributions

The Company’s matching contributions vary based on the matching group to which the employee belongs, as defined in the Plan document.

For employees in matching group one, the Company matches 100% of employee contributions for the first 4% of the participant’s eligible compensation and 50% of employee contributions for the next 2% of the participant’s eligible compensation. For employees in matching group two, the Company matches 100% of employee contributions for the first 2% of the participant’s eligible compensation and 50% of employee contributions for the next 6% of the participant’s eligible compensation. For employees in matching group four, the Company matches 3% of a participant’s eligible compensation for any participant deferring 1-3% of his or her compensation and 100% of employee contributions for any participant deferring 4-8% of eligible compensation. The Company does not provide matching contributions for employees in matching group three.
