The hang-ups in testing of a new computer system that caused the Thrift Savings Plan to postpone the availability of two new investment funds also means the delay of several other services linked to that computer system. Among the more prominent of those is a plan to value accounts daily rather than monthly, which in turn will allow transfers among funds as often as every day, versus the current monthly system. That change will be delayed until October 1, as will the availability of new investment funds tracking small company U.S. stocks and international stocks.
