LIAB invests in US Treasury securities, mainly TIPS, aiming for predictable cashflows through 2048. In 2028, investors can opt for Longevity-Linked Distributions via a closed-end fund with payments up to age 100 or Term Distributions continuing through 2048, or a mix. Both Fund and closed-end funds aim to liquidate by 2048, distributing all assets then ceasing distributions. Initially, monthly payouts are $0.0833 per share, adjusted for inflation, until 2028 when it recalibrates to approximately $0.0760 monthly until 2048. 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 February7, 2025, the fund utilized Stone Ridge for branding instead of LifeX.
