Historical Daily MTM NAV

Download: Schedule of Daily Information

"Shadow Pricing" of the Fund is designed to show the extent of deviation, if any, of the net asset value ("NAV") of the Fund using the amortized cost method of valuation in which, during the calculating the Fund's NAV, portfolio securities are valued at the fund's acquisition cost, as adjusted for amortization of premium or accretion of discount, intended to create a "stable NAV", in comparison to portfolio securities being valued based on available market quotations or current market factors, creating a likely "floating NAV". This calculation is required to be performed at least daily and is subject to the review of the Fund's Board of Trustees. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other Government agency. None of the State Street Corporation, State Street Bank and Trust Company, State Street Global Advisors, SSGA Funds Management, Inc. or their affiliates ("State Street Entities") guarantee the value of your investment at $1.00 per share. Investors should have no expectation of capital support to the Fund from State Street Entities. Although the Fund seeks to preserve the value of an investment at $1.00 per share, it is possible to lose money by investing in the Fund.

Performance quoted represents past performance, which is no guarantee of future results. Investment return and principal value will fluctuate, so you may have a gain or loss when shares are sold. Current performance may be higher or lower than that quoted.

¹Total Annual Fund Operating Expense Waivers. SSGA FM, as the investment adviser to each Fund is contractually obligated, through April 30, 2025 (i) to waive up to the full amount of the advisory fee payable by each Fund, and/or (ii) to reimburse a Fund for expenses to the extent that Total Annual Fund Operating Expenses (exclusive of non-recurring account fees, interest, taxes, extraordinary expenses, acquired fund fees, any class-specific expenses, such as distribution, shareholder servicing, sub-transfer agency and administration fees) exceed 0.07% of average daily net assets on an annual basis (the “Total Annual Fund Operating Expense Waiver”). The Total Annual Fund Operating Expense Waiver may not be terminated prior to April 30, 2025 with respect to any Fund except with approval of the Fund’s Board of Trustees.

The Fund’s investment adviser, SSGA Funds Management, Inc. (the “Adviser” or “SSGA FM”), and its affiliates, may voluntarily reduce all or a portion of their fees and/or reimburse expenses of the Fund or a share class to the extent necessary to maintain a certain minimum net yield, which may vary from time to time and from share class to share class within the Fund, in SSGA FM’s sole discretion (any such waiver or reimbursement of expenses being referred to herein as a “Voluntary Reduction”), or a yield below a specified level, which may vary from time to time in the Adviser’s sole discretion. The Fund has agreed, subject to certain limitations, to reimburse the Adviser and its affiliates for the full dollar amount of any Voluntary Reduction incurred beginning on May 1, 2020. During the fiscal year ended December 31, 2023, the Adviser and its affiliates did not waive fees or reimburse expenses under the Voluntary Reduction. Each of the Adviser and its affiliates may, in its sole discretion, irrevocably waive receipt of any or all reimbursement amounts due from the Fund. Any future reimbursement by the Fund of the Voluntary Reduction would increase the Fund’s expenses and may reduce the Fund’s yield during such period. There is no guarantee that the Voluntary Reduction will be in effect at any given time or that the Fund will be able to avoid a negative yield.

Holdings subject to change.

† The subsidized yield reflects the yield calculation with voluntary reduction currently in effect. Without the reduction returns would have been lower.
