MLDR offers exposure to US Treasury bonds with maturities ranging from 3 to 10 years. The fund uses a bond laddering approach, grouping its securities into seven distinct maturity groups known as rungs. Each rung represents bonds maturing within a specific year from the 3 to 10 years range, starting from the 3 to 4-year group. Each year, the fund moves bonds from each rung to the next shorter maturity, sells those from the shortest rung, and reinvests the proceeds into new bonds for the 9 to 10-year group. These rungs are equally weighted, and the bonds within each rung are weighted based on their market capitalization. Eligible securities must be denominated in US dollars and widely available to the public, with exclusions for certain types like variable-rate and convertible bonds. The fund is updated monthly and may also allocate assets to cash or money market instruments. MLDR seeks to provide consistent exposure to intermediate-term US Treasury bonds.
