TIRXX Investment Objective and Strategy
Nuveen Money Market Fund describes its objective and strategy as follows, from its latest prospectus filed with the SEC by Tiaa-Cref Funds.
Investment objective
The Fund seeks high current income consistent with maintaining liquidity and preserving capital.
Principal investment strategy
The Fund is a government money market fund, as defined in the applicable rules governing money market funds, and as such invests at least 99.5% of its total assets in cash, U.S. Government securities and/or repurchase agreements that are collateralized fully by cash or U.S. Government securities. These investments include (1) securities issued by, or whose principal and interest are guaranteed by, the U.S. Government or one of its agencies or instrumentalities and (2) repurchase agreements involving securities issued or guaranteed by the U.S. Government or one of its agencies or instrumentalities. Short-term, U.S. Government securities generally pay interest that is among the lowest for income-paying securities. Because of this, the yield on the Fund will likely be lower than the yields on funds that invest in longer-term or lower-quality securities.
Generally, the Fund seeks to maintain a share value of $1.00 per share. The Funds investments will be made in accordance with the applicable rules governing the quality, maturity and diversification of securities and other instruments held by money market funds. The Fund maintains a dollar-weighted average maturity of 60 days or less and a dollar-weighted average life to maturity of 120 days or less, and invests in debt obligations with a remaining maturity of 397 days or less. Advisors limits the Funds investments to U.S. Government securities or securities that present minimal credit risks to the Fund and are of eligible quality. A government money market fund is not required to impose liquidity fees or redemption gates, and the Fund does not currently intend to impose such fees and/or gates.
However, the Funds Board of Trustees could elect to subject the Fund to such fees and/or gates in the future. The above list of investments is not exclusive and the Fund may make other investments consistent with its investment objective and policies.
