The Portfolio seeks to achieve its objective by investing, under normal circumstances, its total assets exclusively in:

The Portfolio, under normal circumstances, will invest at least 80% of its net assets (plus the amount of any borrowings for investment purposes) in Treasury Obligations and repurchase agreements collateralized solely by Treasury Obligations.

The Portfolio operates as a “government money market fund” under Rule 2a‑7 of the Investment Company Act of 1940, as amended. As a “government money market fund” under Rule 2a‑7, the Portfolio (1) is permitted to use the amortized cost method of valuation to seek to maintain a stable net asset value (“NAV”) of $1.00 share price, and (2) is not required to impose a liquidity fee on Portfolio redemptions that might apply to other types of money market funds. The Portfolio may invest in shares of other government money market funds.

The Securities and Exchange Commission (“SEC”) imposes strict requirements on the investment quality, maturity, diversification and liquidity of the Portfolio’s investments. Accordingly, the Portfolio invests in U.S. dollar-denominated securities with a remaining maturity of no more than 397 days (with certain exceptions permitted by applicable regulations). The Portfolio maintains a dollar-weighted average portfolio maturity of no more than 60 calendar days, and a dollar-weighted average portfolio maturity as determined without exceptions regarding certain interest rate adjustments under Rule 2a‑7 of no more than 120 calendar days. The Portfolio will

limit its investments to “eligible securities,” as defined by applicable regulations, at the time of acquisition (e.g., government securities, shares of other money market funds, and securities that present minimal credit risks as determined by NTI, pursuant to guidelines approved by the Portfolio’s Board of Trustees). The Portfolio may invest in variable and floating rate instruments. The Portfolio’s investment adviser may consider, among other things, credit and interest rate risks as well as general market conditions when deciding whether to buy or sell investments for the Portfolio. The Portfolio will generally hold a portion of assets in cash to accommodate anticipated redemptions.
