State Street Prime Money Market 

MMK seeks to maximize current income while maintaining capital preservation and liquidity by broadly investing in money market instruments. The actively managed fund employs its credit research team to assess the relative attractiveness of instruments based on the general interest rates and market supply/demand imbalances. The fund invests in US government securities (T-bills, notes, and bonds), USD-denominated certificates of deposit and time deposits from banks, US and non-US commercial paper, high-quality company obligations, asset-backed and mortgage-related securities, and repurchase agreements. The fund invests in low-risk, high-quality debt with maturities of 397 days or less, targeting a dollar-weighted average maturity of no more than 60 days and a dollar-weighted average life of 120 days or less. The fund typically invests over 25% in bank obligations. As share price and NAV are expected to fluctuate, shares may be worth more or less than their original price when sold.
