Money Market Fund: You could lose money by investing in the fund. Although the fund seeks to preserve the value of your investment at $1 per share, it cannot guarantee it will do so. The fund may impose a fee upon sale of your shares or may temporarily suspend your ability to sell shares if the fund's liquidity falls below required minimums because of market conditions or other factors. An investment in the fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The fund's sponsor has no legal obligation to provide financial support to the fund, and you should not expect that the sponsor will provide financial support to the fund at any time.
Returns or yields for the fund would have been lower if a portion of the management fee had not been waived. Review the annual or semiannual report for the most current information.
Please see the prospectus for details about sales charges.
The gross expense ratio is the fund's total annual operating costs, expressed as a percentage of the fund's average net assets for a given time period. It is gross of any fee waivers or expense reimbursement. The net expense ratio is the expense ratio after the application of any waivers or reimbursement. This is the actual ratio that investors paid during the fund's most recent fiscal year. Please see the prospectus for more information.
Investor Class Shares: Minimum initial investment is $1,000 for IRA and CESA accounts, and $2,500 for non-retirement accounts, but these minimums are waived with an initial investment of at least $500 per account and automatic investments of at least $100 per month. Non-Retirement Accounts: If your account balance falls below the minimum, or if you cancel your automatic monthly investment plan prior to reaching the minimum, American Century Investments may redeem the account and send the proceeds to you. Prior to doing so, we will notify you and give you 90 days to meet the minimum or reinstate your automatic monthly investment plan.
Only Investor Class shares are made available to investors directly. Advisor, A, C, I, and Y Classes of shares are only available for purchase by institutions or other financial intermediaries. R, R5, and R6 Classes of shares are only available for purchase by group employer-sponsored retirement plans. Review definitions and minimums for all share classes.
Bloomberg U.S. 1-3 Month Treasury Bill Index
A sub index of the Bloomberg U.S. Short Treasury Index, the Bloomberg U.S. 1-3 Month Treasury Bill Index is composed of zero-coupon Treasury bills with a maturity between 1 and 3 months. As Treasury bonds and notes fall below one year-to-maturity and exit the Bloomberg U.S. Treasury Index, they become eligible for the Bloomberg U.S. Short Treasury Index. It excludes zero coupon strips.
7-Day Current Yield: More closely reflects the current earnings of the fund than the total return.
7-Day Effective Yield: Can be slightly higher than the 7-Day Current Yield because of the effects of compounding. The 7-Day Effective Yield assumes that income earned from the fund's investments is reinvested and generating additional income.
Investment Blend: Reflects the blend of securities owned by a fund. For example, the percentage of foreign or domestic stocks held by an equity fund or the percentage of corporate and government securities owned by a bond fund. The U.S./Foreign Convertibles grouping includes Convertible Bonds, Equity Linked Securities and Convertible Preferred securities.
Weekly Liquidity: The percentage of the fund's assets invested in daily liquid assets, government agency discount notes with remaining maturities of 60 days or less, securities that will mature or are subject to a demand feature that is exercisable and payable within five business days, and receivables scheduled to be paid within five business days.
Daily Liquidity: The percentage of the fund's assets invested in cash, direct obligations of the U.S. government, securities that will mature or are subject to a demand feature that is exercisable and payable within one business day, and receivables scheduled to be paid within one business day.
Market Based NAV (Net Asset Value): The market based price of the fund's portfolio, also known as a "shadow NAV."
Maturity: Describes the portfolio of the fund in terms of the different maturities of the securities it holds.
Weighted Average Maturity (WAM): Uses effective maturity to approximate the remaining term to maturity of a fund's investment portfolio, weighted by dollar amount. Generally, the longer a fund's WAM, the more sensitive it is to changes in interest rates.
