The BackDROP distribution is payable in either:

• One lump sum payment at retirement.
  
  
• Three annual installments (one with your first monthly benefit payment and one each of the following two years thereafter).
  
  Three annual installments are only available to members electing the cash option payment method. Delaying receipt through the three installment option does not increase the amount – that is, you will not receive interest on the second or third payments.
