An employee shall have 30 days from the date on which the System provides the notice required under Section 414(w) of the Internal Revenue Code of 1986, as amended, to elect to not participate in the eligible deferred compensation plan or to elect to increase or reduce the initial amount of elective deferrals made to the plan. In the absence of such affirmative election, the employee shall be automatically enrolled in the plan on the first day of the calendar month, or as soon as administratively practicable thereafter, following the 30th day from the date on which the System provides the required notice. An employee who has been automatically enrolled in the plan under this subsection (b) may elect, within 90 days of enrollment, to withdraw from the plan and receive a refund of amounts deferred, adjusted by applicable earnings and fees. An employee making such an election shall forfeit all employer matching contributions, if any, made with respect to such refunded elective deferrals and such forfeited amounts shall be used to defray plan expenses. Any refunded elective deferrals shall be included in the employee's gross income for the taxable year in which the refund is issued.
