The Fannie Mae LIBOR rates are determined from information that is available as of 11:00 a.m. (London Time) on the second to last business day of each month. Fannie Mae makes these rates available by the last business day of each month.

LIBOR is an abbreviation for "London Interbank Offered Rate," and is the interest rate offered by a specific group of London banks for U.S. dollar deposits of a stated maturity. LIBOR is used as a base index for setting rates of some adjustable rate financial instruments, including Adjustable Rate Mortgages (ARMs).

Note that while this is evidently based on the daily LIBOR released by the BBA, this is not the same index. For more on the daily LIBOR, click here.
