LLDR focuses on long-term US Treasury bonds maturing between 10 and 30 years, employing a bond laddering technique structured into 20 annual rungs. Each rung holds bonds within a specific maturity range, starting with the 10 to 11-year group. Each year, bonds move to the next shorter maturity rung, and those previously in the shortest rung are sold, with proceeds going into the acquisition of new securities for the 29 to 30-year range. The rungs are equally weighted, and the bonds within each rung are weighted based on their market capitalization. Eligible securities must be publicly available US Treasury bonds denominated in US dollars, with certain types like variable-rate and convertible bonds excluded from consideration. The fund undergoes monthly updates and may hold cash or money market instruments to align with its overall strategy. LLDR aims to maintain exposure to long-term government bonds while balancing its holdings.
