I am a Federal employee covered by the TSP (Thrift Saving Plan) structure. (This has only a few funds including a S&P 500, a Small Cap index, a Foreign index, a Leaman bond index and a cash/treasury fund) I only recently discovered that since July of 01 other appropriate IRA funds could be transferred into this account. (I know that TSP funds can be transferred out at retirement to other funds like Vanguard, etc.) I have two IRAs (OPTFX and ANWPX), which I have had since the 1980s. I am not unhappy although I would not choose to buy these funds now they were pretty good funds for a nonknowledgeble person at the time and probably would not be saved at all if not invested at the time. Anyway, I am trying to determine whether to transfer these into the TSP account or just leave them separate as a bit of diversification. The original purchase loads have been paid already and the expense ratios are not crazy (1.2% and .87%) but more that the TSP S&P index which is actually lower than Vanguard. Is it worth it to transfer for lower fees and from managed funds into index funds where the funds are owned already? I have 3 to 5 years until retirement but I expect these funds to be used over many years after that.
