 contributions may not exceed the dollar amount provided by the Internal Revenue Code ("the Code"), which was $23,000 for 2024.

The Plan also permits each participant to make after-tax contributions, including Roth 401(k) contributions, to the Plan. However, total pre-tax and after-tax contributions generally may not exceed 50% of the participant’s total eligible compensation.

Generally, participants over 50 years of age may elect up to 25% of eligible compensation as either an additional pre-tax catch-up contribution or Roth 401(k) catch-up contribution, which was limited by the Code to $7,500 in 2024.

In addition to the ability to make simultaneous tax deferred and after-tax contributions, the Plan also allows for a participant’s contributions to automatically continue on an after-tax basis once the pre-tax contribution limit has been reached for that year. Participants, who elect to continue contributing to the Plan on an after-tax basis, will contribute at the same pre-tax contribution percentage that was in effect when the limit was reached for that year. In determining the amount of pre-tax and after-tax contributions allowed under the Plan, annual compensation limits are imposed by the Code.

New hires who do not decline enrollment in the Plan within 90 days after first becoming eligible to join the Plan, will be automatically enrolled in the Plan and a pre-tax contribution of 6% will be deducted from the participant’s pay and invested in the T. Rowe Price Retirement fund designed for the participant’s age group.

The Company contributes on behalf of each eligible participant, an amount equal to 100% of the participant’s contribution up to 6% of eligible compensation. The amount of any Company matching contributions is subject to certain limitations of the Code. In 2010, the Plan became a safe harbor 401(k) plan.
