Holiday Closing — Some financial markets will be closed on Monday, September 7th in observance of the Labor Day holiday.  The Thrift Savings Plan will also be closed.  Transactions that would have been processed Monday night (September 7th) will be processed Tuesday night (September 8th), at Tuesday's closing share prices.

Daily Maintenance — There will be daily routine system maintenance and backups between 12:00 a.m. and 4:00 a.m., Eastern time, which may cause slower than normal transaction response times.
