I am an LEO and considering retirement at age 50. As I read the TSP phamplets and web page, there appears to be a withdraw option of monthly payments for a specific dollar amount that remains the same for five years or 59 1/2 whichever is longer and is not related to the life expectancy option the TSP web page. More specifically, it appears this option leaves a persons account balance directly with TSP and does not include a roll-over to a traditional IRA. There is very little information concerning this option. Does this option meet the IRS's criteria of Rule 72T thereby protecting these monthly withdraws before 55 from the 10% early withdraw penalty.
