BofA Merrill Lynch (BofAML) 1-Year T-Bill Index
An unmanaged index that measures the returns of 12-month Treasury bills. Consists of a single issue purchased at the beginning of a month and held for the full month. At the end of that month, that issue is sold and rolled into a newly-selected issue. The issue selected at each month-end rebalancing is the outstanding T-bill with the longest maturity.
