C000255640 Investment Objective and Strategy
LifeX Durable Income ETF describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Stone Ridge Trust.
Investment objective
The LifeX Durable Income ETF (the Fund) seeks to provide reliable monthly distributions consisting of income and principal. There can be no assurance that the Fund will achieve its investment objective.
Principal investment strategy
The Investments . The Fund is an exchange-traded fund (ETF) that pursues its investment objective by investing in debt securities issued by the U.S. Treasury (which we refer to as U.S. Government Bonds) as well as money market funds that invest exclusively in U.S. Government Bonds or repurchase agreements collateralized by such securities. Securities issued by the U.S. Treasury historically have not had credit-related defaults (i.e., failures to fulfill payment-related obligations such as interest or principal payments) and therefore such securities are generally considered to be credit risk-free (i.e., free of the risk of non-payment of either interest or principal). When constructing its portfolio of U.S. Government Bonds, the Fund seeks to select particular bond maturities and investment amounts that enable the Fund to lock in interest rates and reliably sustain its planned distributions and recalibration strategy.
As of March 31, 2026, the average duration (which is a measure of a bonds sensitivity to interest rates) of the Funds U.S. Government Bonds is approximately 13.8 years. The Offering . The Fund is one of many series of Stone Ridge Trust (the Trust) designed to provide a paycheck-like experience for investors by making predictable monthly distributions consisting of income and principal from its investments. Every five years, beginning in January of 2030, the Funds per-share distribution rate will be recalibrated based on current market interest rates to a level that the Adviser believes would result in the distribution of substantially all of the Funds assets over a 40-year time horizon. The Fund will calibrate its distribution rate by calculating the payout rate of a 40-year Treasury bond ladder and adjusting for the Funds Unified Management Fee.
The purpose of including a portion of principal in the Funds distributions is to provide investors with a higher level of cashflow than would be possible from distributing the Funds interest income alone. The purpose of recalibrating the distribution rate every five years is to enable the Fund to operate and provide monthly distributions in perpetuity. As a result of returning principal and recalibrating periodically, the Funds per-share distribution rate is expected to decline over time. Distributions . From the date of its launch until the date of the first recalibration of its distribution rate in January 2030, the Fund intends to make an identical distribution each month equal to $0.8333 per outstanding share of the Fund. For example, an investor who purchases 10,000 shares before the Funds initial distribution is expected to receive $8,333 in total distributions per month until the next recalibration date.
The following table illustrates the Funds intended distributions for each of the next five years for an investor who purchases 10,000 shares, incorporating an estimate of the effect of its periodic recalibrations, estimated based on current market interest rates as of March 31, 2026. Year Total Distributed Per Year Total Distributed Per Month 2026 $100,000 $8,333 2027 $100,000 $8,333 2028 $100,000 $8,333 2029 $100,000 $8,333 2030 $95,150.18 $7,930.02 An investor purchasing 10,000 shares intra-year after some of the Funds monthly distributions have already been paid will receive less than the total yearly distributions as a result. The Fund intends to make the distributions discussed above on or about the third (3rd) business day of each calendar month. See Principal Investment RisksDistribution and Interest Rate Risk for more information on the distribution rates.
