An announcement entitled, "Moody's assigns a Aaa-mf rating to State Street Institutional US Government Money Market Fund" tells us, "Moody's Investors Service ("Moody's") has assigned a Aaa-mf rating to State Street Institutional US Government Money Market Fund, as well as to its six share classes (together, "the Funds"): State Street Institutional US Government Money Market Fund -- Premier Class; State Street Institutional US Government Money Market Fund - Investor Class; State Street Institutional US Government Money Market Fund - Administration Class; State Street Institutional US Government Money Market Fund - Investment Class; State Street Institutional US Government Money Market Fund -- Institutional Class; and, State Street Institutional US Government Money Market Fund - M Class. The Aaa-mf rating reflects our view of the Funds' ability to meet the primary objectives of preserving capital and liquidity. Our view is also supported by the Funds' high scores across all key rating considerations. The Funds score high with respect to credit quality as it invests primarily in US government and agency obligations, US Treasury securities, obligations issued by US government sponsored entities as well as repurchase agreements backed by government securities. We expect the Funds to maintain high credit quality, low asset concentration and a short-weighted average maturity. The Funds also scored high with respect to market risk exposure and liquidity. Under our net asset value stress test, the Funds' underlying portfolio exhibits relatively modest volatility. They also display a strong liquidity profile that is supported by a diverse investor base that is primarily made up of institutional clients and high levels of overnight and near-term liquidity. The Funds are organized in a master-feeder structure in which six distinct share classes comprise one feeder fund. The feeder invests all of its investable assets and interests into the assets of the master portfolio. Our assessment and credit rating of these share classes is based on the quality of the master portfolio. State Street Institutional US Government Money Market Fund was established in 2007 with the objective of maximizing current income, preserving capital and liquidity while maintaining a constant per share net asset value. State Street Global Advisors Funds Management, Inc. (SSGA FM) is the investment adviser to the Fund. The company is a wholly-owned subsidiary of State Street Corporation (A1 stable)."
