You may join the plan once you have satisfied the plan’s eligibility requirements defined in the plan document and your Summary Plan Description. Once satisfied, you must complete a beneficiary form and an enrollment form if the plan is a 401(k) plan or if the plan allows participants to direct the investment of their account balance. Whether or not you decide to defer a percentage of your pay to the plan (if a 401(k) plan), an enrollment form should be completed so that your investment selections are on file in the event that the employer makes an employer contribution to the plan to which you are entitled to a share. A beneficiary form should also be completed so that the beneficiary of your account is established in the event it is needed.
