LIBD invests in US Treasury securities, mainly TIPS, aiming for predictable cashflows through 2065. In 2045, investors can opt for Longevity-Linked Distributions via a closed-end fund with payments up to age 100 or Term Distributions continuing through 2065, or a mix. Both Fund and closed-end funds aim to liquidate by 2065, distributing all assets then ceasing distributions. Initially, monthly payouts are $0.0833 per share, adjusted for inflation, until 2045 when it recalibrates to approximately $0.0760 monthly until 2065. Inflation adjustments are based on the Consumer Price Index and distributions are made around the 3rd business day each month. A portion of each monthly distribution is considered return capital, reducing the amount for investment and lowering the investor's tax basis in their shares. Before February14, 2025, the fund utilized Stone Ridge for branding instead of LifeX. On Sept. 18, 2025 the Issuer consolidated four other funds from this series (2061-2064) into this fund, increasing AUM by $11.8 million.
