FERS Average Account Balances by Age and Tenure* July 2007 .
* Average account balances reflect all active participants with a balance, whether or not they are currently contributing. Tenure is calculated using the TSP Service Computation Date (TSP-SCD), which is reported by the agencies and is used to determine the vesting of agency automatic contributions. For the purposes of this report, the TSP-SCD is being used as an approximate for the date of hire. However, for some participants, the TSP-SCD is not the same as the date of hire due to breaks-in-service and credited service.
