Interest in the annuity savings fund shall be credited to the date on which, as applicable, a member dies, has his/her contributions refunded, retires where the member elects to receive an annuity from the system, or receives, following retirement, a total withdrawal distribution of his/her annuity savings, or membership otherwise ceases, and when membership ceases no interest will be allowed on contributions left in the annuity savings fund.
