Even while shifting previously invested money away from stocks, though, investors have been continuing to put nearly half of their new investments into the C fund through payroll withholdings. Through April, just under $2 billion of new money has gone into both the C and G funds, nearly $541 million into the F fund and about $173 million combined into the S and I funds. During the current TSP open season that runs through June 30, investors may change the level of their investments. Allocations among the TSP funds of ongoing investments can be changed at any time.
