Terms and Definitions

USTREAS T-Bill Auction Ave 3 Mon: USTREAS T-Bill Auction Ave 3 Mon is an index that measures the performance of the average investment rate of U.S. Treasury bills (T-Bills) with a three-month maturity. Three-month T-Bills are short-term securities issued by the U.S. government that are generally considered to be risk-free. In calculating index results, Morningstar, the index provider, determines the arithmetic mean of the investment rates on all three-month T-Bills issued during a given month as reported by the U.S. Treasury's Bureau of the Public Debt. The investment rate is then converted into a price and a monthly return, assuming that the T-Bill is held to maturity.
