MTA - 12-Month
Treasury Average Index. This index is based on the average annual monthly
yields of U.S. Treasury Securities, (T
-Bill) adjusted to a constant maturity of one year, as made available by
the Federal Reserve. The index is determined by adding together the
monthly yields for the most recent 12 months and dividing by 12. Since
it's an average, higher yields in some months are offset by lower yields
in others. It's considered another sound choice for home investment, since
interest rate increases take longer to affect the 12-MTA than other ARM
indices. The MTA index does not move as slowly as the Cost Of Funds Index
(COFI), but it does have a lower margin and lower life rate
cap.
