Fund profile

As filed in the prospectus · 2026 Q1

The Fund seeks to provide investment results that, before fees and expenses, correspond generally to the price and yield performance of the iBoxx 3-Year Target Duration TIPS Index (the Underlying Index).

Strategy · summarised

The fund tracks the iBoxx 3-Year Target Duration TIPS Index, which holds inflation-protected U.S. Treasury securities with a targeted average modified adjusted duration of approximately three years and maturities between one and ten years, rebalancing monthly to maintain that duration target. The fund generally replicates the index by holding substantially all of its constituent securities in the same proportions, though it may use representative sampling when full replication is impracticable, which could cause the fund's performance to diverge from the index.

Risk profile

Interest-rate and credit-spread sensitivity, both in years · as of 2026Q2

This fund filed the credit-spread disclosure and reported no sensitivity — measured, and the answer is none.

Where the loss would come from. The two shocks are the same size, so this is the balance of the fund's two sensitivities rather than a bet on one moving more.

Interest rates100%

Filers report the impact of a 0.01% move only, so the total is our own scaling of that one number and overstates the loss on most bonds — read it as approximate, never as precise. The two sensitivities overlap rather than add up: they measure the same positions against different shocks, which is why the durations above are shown side by side and never summed.

Share of duration at each point, shortest first. A positive figure loses value when spreads widen; a negative one offsets — a credit hedge.
