In lieu of receiving a monthly allowance that is less than ten dollars ($10) per month, the beneficiary or survivor entitled to the allowance may elect to receive the actuarial equivalent of the monthly allowance in one payment. Payment of the actuarial equivalent amount pursuant to that election discharges this system from all further liability for the allowance otherwise payable. The beneficiary or survivor may make the election provided by this section within 90 days from the date this system notifies him or her of the right to make the

election.
