Fund profile
As filed in the prospectus · 2025 Q4
The State Street SPDR Bloomberg 3-12 Month T-Bill ETF (the Fund) seeks to provide investment results that, before fees and expenses, correspond generally to the price and yield performance of an index that tracks the 3-12 month sector of the United States Treasury Bill market.
The fund tracks the Bloomberg 3-12 Month U.S. Treasury Bill Index using a sampling strategy, holding a subset of the index's securities selected to replicate its risk and return characteristics. Because the fund samples rather than holding all index constituents, its performance may diverge from the index. The fund invests at least 80% of assets in index securities or economically identical alternatives, with the remainder in cash, money market instruments, or other debt securities for cash management.

Allocation
Asset groups · long / short shown separately, never netted · 2026 Q2
| Cash & short-term | 107.73% |
These positions come to 107.73% of the fund's net assets. This counts only what the fund reported holding — the holdings disclosure covers assets, not liabilities such as borrowings — so it is not expected to reconcile to 100%.

Return profile
Total return as filed — price change plus distributions reinvested · trailing figures to Apr 2026
May 2026 and Jun 2026 have been filed since the trailing figures were struck, so they are not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.
Debt profile
What this fund holds — value-weighted across its bond and securitized long positions · as of 2026-06-30
Based on what filers reported; a filer that never reported a flag also reads as none.
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 rates | 100% |
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.
