Growth Fund

1. What is the fund's investment objective?

Growth seeks long-term capital growth by investing primarily in common stocks.

2. What is the fund's investment strategy?

The fund managers look for large company stocks that they believe will increase in value over time. They use a growth investment strategy developed by American Century that looks for companies whose earnings and revenues are not only growing, but growing at a successively faster, or accelerating, pace. Accelerating growth is shown, for example, by growth that is faster this quarter than last or faster this year than the year before.

Using American Century's extensive computer database, the fund managers track financial information for thousands of companies to research and select the stocks they believe will be able to sustain accelerating growth. This strategy is based on the premise that, over the long term, the stocks of companies with accelerating earnings and revenues have a greater-than-average chance to increase in value. This aggressive investment strategy, which pursues superior long-term returns for fund shareholders, also results in the risks described in the next section.

The fund managers do not attempt to time the market. Instead, under normal market conditions, they intend to keep Growth essentially fully invested in stocks regardless of the movement of stock prices generally. When the fund managers believe it is prudent, they also may invest assets in nonleveraged futures and options. "Nonleveraged" means that the fund may not invest in futures and options where it would be possible to lose more than the fund invested. Futures and options can help the fund's cash assets remain liquid while performing more like stocks.

Additional information about Growth's investments is available in its annual and semiannual reports. In these reports you will find a discussion of the market conditions and investment strategies that significantly affected the fund's performance during the most recent fiscal period. You may get these reports at no cost by calling us.

3. What are the significant risks of investing in the fund?

In summary, Growth is intended for investors who seek long-term capital growth through an aggressive equity fund and who are willing to accept the risks associated with the fund's investment strategy.

Tax-Managed Value Fund

1. What is the fund's investment objective?

Tax-Managed Value seeks long-term capital growth by investing primarily in common stocks while attempting to minimize the impact of federal taxes on shareholder returns.

2. What is the fund's investment strategy?

The fund managers use a value investment strategy to look for stocks of medium to large companies the fund managers believe are undervalued at the time of purchase. Companies may be undervalued due to market declines, poor economic conditions, actual or anticipated bad news regarding the issuer or its industry, or because they have been overlooked by other investors. To identify these companies, the fund managers look for companies with earnings, cash flows and/or assets that may not be reflected accurately in the companies' stock prices.

To minimize taxable distributions, the fund managers employ the following tax-sensitive techniques that may sometimes be inconsistent with the fund's objective of long-term capital growth

While the fund seeks to minimize taxable distributions to shareholders, it may realize taxable gains and earn some dividends. For example, the fund managers may elect to sell a security, even if the sale results in a taxable gain, if they determine the tax impact of the sale is outweighed by other factors. Such other factors may include the investment risk of holding the security or the availability of a replacement security that has a better potential return. In addition, redemptions by shareholders could make it necessary for the fund to sell securities, potentially resulting in capital gains. Under certain circumstances, payment of the redemption price may be made in whole or in part by a distribution in kind of securities from the fund in lieu of cash, at the fund managers' discretion.

Investors who frequently redeem their shares generate additional transactional costs for the fund and may cause the fund to recognize capital gains and greater brokerage commissions that must be borne by the fund's remaining shareholders. To encourage long-term investing, the fund applies a 2.0% redemption fee to shares held for less than one year. The fees will be paid directly to the fund and will be used to help reimburse the fund for costs incurred by the fund when buying and selling securities.

3. What are the significant risks of investing in the fund?

In summary, Tax-Managed Value is intended for investors who seek long-term capital growth on an after-tax basis and who are willing to accept the risks associated with the fund's investment strategy.

4. What are the fund's fees and expenses?

There are no sales loads, fees or other charges

The fund charges a redemption/exchange fee of 2.0% of the value of the shares sold within one year of their purchase.

The following table describes the fees and expenses you will pay if you buy and hold shares of the fund.

--------------------------------------------------------------------------------
Shareholder Fees
(fees paid directly from your investment)
--------------------------------------------------------------------------------
    Redemption/Exchange Fee
    (as a percentage of amount redeemed/exchanged)
      Shares held less than one year(1)                           2.0%
      Shares held for one year or more                            None
--------------------------------------------------------------------------------
  1. The fees withheld from redemption proceeds are paid to the fund.
--------------------------------------------------------------------------------
Annual Fund Operating Expenses
(expenses that are deducted from fund assets)
--------------------------------------------------------------------------------
    Management Fee                                          1.10%(1)
    Distribution and Service (12b-1) Fees                   None
    Other Expenses                                          0.00%(2)
    Total Annual Fund Operating Expenses                    1.10%
--------------------------------------------------------------------------------
  1. The fund has a stepped fee schedule. As a result, the fund's management fee rate generally decreases as fund assets increase.
  2. Other expenses, which include the fees and expenses of the fund's independent directors and their legal counsel as well as interest, were less than 0.005% for the most recent fiscal year.

Example

Assuming you . . .

. . . your cost of investing in the fund would be:
--------------------------------------------------------------------------------
                  1 year                        3 years
--------------------------------------------------------------------------------
                   $320                          $349
--------------------------------------------------------------------------------

You would pay the following expenses if you did not redeem or exchange your shares at the end of the periods shown below:

--------------------------------------------------------------------------------
                  1 year                        3 years
--------------------------------------------------------------------------------
                   $112                          $349
--------------------------------------------------------------------------------

Of course, actual costs may be higher or lower. Use this example to compare the costs of investing in other funds.

Vista Fund

1. What is the fund's investment objective?

Vista seeks long-term capital growth by investing primarily in common stocks.

2. What is the fund's investment strategy?

The fund managers look for stocks of companies that they believe will increase in value over time. A majority of the stocks selected are issued by medium- and smaller-sized companies, although the fund may own stock of larger companies, too. The fund managers use a growth investment strategy developed by American Century that looks for companies whose earnings and revenues are not only growing, but growing at a successively faster, or accelerating, pace. Accelerating growth is shown, for example, by growth that is faster this quarter than last or faster this year than the year before.

Using American Century's extensive computer database, the fund managers track financial information for thousands of companies to research and select the stocks they believe will be able to sustain accelerating growth. This strategy is based on the premise that, over the long term, the stocks of companies with accelerating earnings and revenues have a greater-than-average chance to increase in value. This aggressive investment strategy, which pursues superior long-term returns for fund shareholders, also results in the risks described in the next section.

The fund managers do not attempt to time the market. Instead, they intend to keep Vista essentially fully invested in stocks regardless of the movement of stock prices generally. When the fund managers believe that it is prudent, they also may invest assets in nonleveraged futures and options. "Nonleveraged" means that the fund may not invest in futures and options where it would be possible to lose more than the fund invested. Futures and options can help the fund's cash assets remain liquid while performing more like stocks.

Additional information about Vista's investments is available in its annual and semiannual reports. In these reports you will find a discussion of the market conditions and investment strategies that significantly affected the fund's performance during the most recent fiscal period. You may get these reports at no cost by calling us.

3. What are the significant risks of investing in the fund?

In summary, Vista is intended for investors who seek long-term capital growth through an aggressive equity fund and who are willing to accept the risks associated with the fund's investment strategy.

Balanced Fund

1. What is the fund's investment objective?

Balanced seeks long-term capital growth and current income by investing approximately 60% of the fund's assets in equity securities, and the remainder in bonds and other fixed-income securities.

2. What is the fund's investment strategy?

For the equity portion of the Balanced portfolio, the fund managers utilize quantitative management techniques in a two-step process that draws heavily on computer technology. In the first step, the fund managers rank stocks, primarily the 1,500 largest publicly traded companies in the United States (measured by the value of their stock). These rankings are determined by using a computer model that combines measures of a stock's value, as well as measures of its growth potential. To measure value, the managers use ratios of stock price-to-book value and stock price-to-cash flow, among others. To measure growth, the managers use, among others, the rate of growth of a company's earnings and changes in its earnings estimates.

In the second step, the managers use a technique called portfolio optimization. In portfolio optimization, the managers use a computer model to build a portfolio of stocks from the ranking described earlier that they think will provide the optimal balance between risk and expected return. The goal is to create an equity portfolio that provides better returns than the S&P 500 without taking on significant additional risk.

The fixed-income portion of the fund's portfolio is invested in a diversified portfolio of high-grade government, corporate, asset-backed and similar securities payable in U.S. currency, with a minimum of 25% of the fund's assets in fixed-income securities. At least 80% of the fixed-income assets will be invested in securities that, at the time of purchase, are rated within the three highest categories by a nationally recognized statistical rating organization. The remaining portion may be invested in securities rated in the fourth and fifth highest categories. Under normal market conditions the weighted average maturity for the fixed-income portfolio will be in the three- to 10-year range.

Additional information about Balanced's investments is available in its annual and semiannual reports. In these reports you will find a discussion of the market conditions and investment strategies that significantly affected the fund's performance during the most recent fiscal period. You may get these reports at no cost by calling us.

3. What are the significant risks of investing in the fund?

In summary, Balanced is intended for investors who want an investment that combines the potential for long-term capital growth with the income produced from a portfolio of intermediate-term fixed-income securities, and who are willing to accept the risks associated with the fund's investment strategy.

High-Yield Fund

1. What is the fund's investment objective?

High-Yield seeks high current income by investing in a diversified portfolio of high-yielding corporate bonds, debentures and notes. As a secondary objective, the fund seeks capital appreciation, but only when consistent with the primary objective of maximizing current income.

2. What is the fund's investment strategy?

The fund managers invest the fund's assets primarily in lower-rated debt securities, which are subject to greater credit risk and consequently pay higher yields. Securities of this type are subject to substantial risks including price volatility, liquidity risk and default risk. You should carefully assess the risks associated with an investment in the fund.

Under normal market conditions, the fund managers will maintain at least 80% of the fund's total assets in high-yielding corporate bonds and other debt instruments (including convertible and preferred securities). The remaining assets may be invested in common stocks or other equity-related securities. The fund managers buy securities that are below investment grade, including so-called junk bonds. Issuers of these securities often have short financial histories or have questionable credit.

Up to 40% of the fund's total assets may be invested in fixed-income obligations of foreign issuers. Under normal market conditions, the fund may invest up to 20% of its assets, and for temporary defensive purposes, up to 100% of its assets, in short-term money market instruments.

The purple bar in the following chart shows the authorized credity quality range for the fund.

Limited-Term Bond Fund

1. What is the fund's investment objective?

Limited-Term Bond seeks income from investments in corporate bonds and other debt obligations.

2. What is the fund's investment strategy?

The fund buys quality, short-term corporate bonds and other debt securities. Corporate bonds generally are issued by companies to finance existing operations or to expand their business. Under normal market conditions, the fund managers will invest most of the fund's assets in investment-grade securities. The remainder will be invested in short-term money market instruments.

The fund managers actively manage the fund, adjusting its weighted average portfolio maturity in response to expected changes in interest rates. If interest rates are expected to rise, the weighted average maturity of the fund will be shortened to protect its net asset value from the effects of falling bond prices. If interest rates are expected to fall, the weighted average maturity will be increased to take advantage of potentially increasing bond prices.

The weighted average maturity of the fund is expected to be five years or less.

Additional information about Limited-Term Bond's investments is available in its annual and semiannual reports. In these reports you will find a discussion of the market conditions and investment strategies that significantly affected the fund's performance during the most recent fiscal period. You may get these reports at no cost by calling us.

3. What are the significant risks of investing in the fund?

In summary, Limited-Term Bond is intended for investors who seek a competitive level of income with limited price volatility.
