From the Federal Register

The Federal Retirement Thrift Investment Board (Agency) amends its interfund transfer (IFT) regulations to limit the number of interfund transfer requests to two per calendar month. After a participant has made two interfund transfers in a calendar month, the participant may make additional interfund transfers only into the Government Securities Investment (G) Fund until the first day of the next calendar month.

This rule is effective on May 1, 2008.
