I was hired 8 December 1986, and no doubt during my indoctrination into the world of the federal employee, received a pamphlet describing the FERS system. I still have that document. (I'm a sick man).
From the OPM FERS guide dated September 1986, and quoting exactly:
“Overview
Why FERS?
The need for a new retirement system for Federal employees began with Public Law 98-21, which provided that Federal employees hired after December 31, 1983 would be covered by Social Security.
A second law, Public Law 98-168, provided for a transition period from January 1, 1984 to January 1, 1986 for employees hired after December 31, 1983. During this period employees were fully covered under Civil Service Retirement System (CSRS) and Social Security benefits. This transition period was extended to December 31, 1986 with the passage of Public Law 99-335, which established the Federal Employees Retirement System (FERS).”
Later, when talking about the “Savings Plan”:
“All Federal employees covered by FERS on January 1, 1987, are eligible to participate in the Savings Plan. Employees hired after that date will generally have 6-12 month waiting period.”
(Note: This guide is so old, it never refers to the “Thrift Savings Plan (TSP)”….Just “The Savings Plan”.)
So, I think the answer to the question is that FERS, and therefore TSP, didn’t really exist before 1 January 1987! You can’t contribute to something that didn’t exist!
I also recall a delay after that date, and thus the lump sum payment for the first few months. In fact, check out the PDF document currently available on the TSP site. (
http://www.tsp.gov/forms/comparison.pdf) According to this, the inception date for the G fund was 1 April 1987. (C and F inception date 29 January 1988). So, that may explain my memory of a lump sum contribution...it may have been for pay periods prior to 1 April 1987. Just don't know if it was from 1 January to 1 April 1987, or from actual date of hiring to 1 April 1987.
Still need to check my personal records.
