The following sentences should be added to the end of the paragraph introducing each fund's Annual
Total Returns bar chart in the section on "Fund Performance History."

          Account fees are not reflected in the chart below. If they had been
          included, returns would be lower than those shown.

For those prospectuses without a Shareholder Fees table, the following table should be inserted to
immediately precede the "Annual Operating Expenses" table in the "Fees and Expenses" section.

          SHAREHOLDER FEES (FEES PAID DIRECTLY FROM YOUR INVESTMENT)

              Century are less than $10,000. See "Account Maintenance Fee"
              under "Investing with American Century" for more details.

For those prospectuses with a Shareholder Fees table, the Maximum Account Maintenance Fee

appropriate.

Manage Your Account."

The following paragraph should be inserted immediately after the paragraph captioned "Minimum
Initial Investment Amount" in the section on "Investing with American Century."

          ACCOUNT MAINTENANCE FEE

          We charge a $12.50 semiannual account maintenance fee to investors
          whose total investments with American Century are less than $10,000.
          We will determine the amount of your total investments twice per year,
          generally the last Friday in October and April. If your total
          investments are less than $10,000 at that time, we will redeem shares
          automatically in one of your accounts to pay the $12.50 fee. Please
          note that you may incur a tax liability as a result of the redemption.
          In determining your total investment amount, we will include your
          investments in American Century funds held in all personal accounts
          and IRAs including SEP-, SARSEP- and SIMPLE-IRAs (but no other
          retirement plan accounts) registered under your Social Security
          number. We will not charge you the fee as long as you choose to manage
          your account exclusively online. You may enroll for exclusive online
          account management on our Web site. To find out more about exclusive
          online account management, visit www.americancentury.com/info/demo.
