Dear Investor:

Thank you for reviewing our semiannual report for the six months ended January 31, 2013. This report offers a macroeconomic and financial market overview of the period (below), followed by fund performance, a schedule of fund investments, and other financial information.

For additional, updated information on fund performance, key factors that affected asset returns, and other insights regarding the investment markets, we encourage you to visit our website, americancentury.com. Also, the next annual report will provide additional perspective from our portfolio management team.

“Risk-On” Rebound After Second-Quarter Slump in 2012

Capital market performance from July 31, 2012 to January 31, 2013 reflected rebounds in investor sentiment and riskier asset returns from their slump in the second quarter of last year. Second-quarter concerns about the European financial system and slowing global economic growth translated to further aggressive monetary intervention by major central banks, including the U.S. Federal Reserve (the Fed), the European Central Bank, and the Bank of Japan.

Aggressive monetary policy, which included a third round of bond buying (“quantitative easing”) by the Fed (“QE3”), helped trigger increased optimism about the financial and economic outlooks for slumping developed nations. This encouraged investors to take more risk and reach for yield, boosting the performance of stocks and high-yield bonds over government bonds.

The risk-on rebound was especially notable in non-U.S. equity markets—the MSCI EAFE Index (a popular non-U.S. stock benchmark) returned 18.60% for the six-month period, compared with 9.91% for the S&P 500 Index, representing the U.S. stock market. High-yield U.S. bond benchmarks also posted gains, while U.S. and global treasury securities indices generally retreated. The 10-year U.S. Treasury yield rose from 1.47% to 1.99%.

The U.S. and global economies are showing signs of growing at a quicker pace this year, but in the U.S. we still expect that pace to be subpar, hampered by high unemployment and lingering fiscal concerns. Inflation expectations and rising interest rates are also potential wild cards. Under these conditions, we continue to believe in a disciplined, diversified, long-term investment approach, using professionally managed stock and bond portfolios for meeting financial goals. We appreciate your continued trust in us in this challenging environment.

Sincerely,

Jonathan Thomas

President and Chief Executive Officer

Independent Chairman’s Letter

Don Pratt

Dear Fellow Shareholders,

The board has once again completed its annual review of the advisory contract between the American Century Investments mutual funds overseen by the board and the funds’ advisor, American Century Investment Management, Inc. This process, often referred to as the 15(c) review, involves the independent directors considering all of the material monitored throughout the year and evaluating a wide range of factors to determine whether the management fee paid by each fund to the advisor is reasonable.

The independent directors’ rationale for this decision is provided in detail in this, or in a previous, report. However, there are several highlights that should be of interest to all shareholders.

•	Fund performance and client service continue to be rated among the industry’s best.

•	Target date and other asset allocation products continue to successfully gather assets and industry acclaim.

•	Compliance programs continue to function successfully with no issues impacting shareholder interests.

•	Fees were found to be within an acceptable competitive range, with minor fee waivers being negotiated on five funds.

Knowing that most shareholders are long term investors, the board was particularly pleased with our succession planning review. Talented professionals are being added within portfolio management and experienced managers have been added to the senior management team.

Overall it was a very positive review for the American Century Investments mutual funds during a challenging market environment.

Best personal regards,

Don Pratt

A Class shares have a 5.75% maximum initial sales charge and may be subject to a maximum CDSC of 1.00%. C Class shares redeemed within 12 months of purchase are subject to a maximum CDSC of 1.00%. The SEC requires that mutual funds provide performance information net of maximum sales charges in all cases where charges could be applied.

The Russell 3000 Index represents approximately 98% of the investable U.S. equity market and provides a broad measure of equity performance. The Barclays U.S. Aggregate Bond Index represents the U.S. investment-grade fixed-rate bond market and provides a broad measure of bond market performance. Performance for these indices is provided for reference only. Neither index is intended to represent the composition of the portfolio, which invests in a mix of equity and fixed-income securities. (See the Schedule of Investments for the LIVESTRONG Portfolio’s asset allocations as of the date of this report.)

Data presented reflect past performance. Past performance is no guarantee of future results. Current performance may be higher or lower than the performance shown. Investment return and principal value will fluctuate, and redemption value may be more or less than original cost. To obtain performance data current to the most recent month end, please call 1-800-345-2021 or visit americancentury.com. A LIVESTRONG Portfolio’s target date is the approximate year when investors plan to start withdrawing their money. The principal value of the investment is not guaranteed at any time, including at the target date. The performance of LIVESTRONG Portfolios is dependent on the performance of their underlying American Century Investments funds, and will assume the risks associated with these funds. The risks will vary according to each LIVESTRONG Portfolio’s asset allocation, and a fund with a later target date is expected to be more volatile than one with an earlier target date.

Unless otherwise indicated, performance reflects Investor Class shares; performance for other share classes will vary due to differences in fee structure. For information about other share classes available, please consult the prospectus. Data assumes reinvestment of dividends and capital gains, and none of the charts reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Returns for the indices are provided for comparison. The fund’s total returns include operating expenses (such as administrative fees) that reduce returns, while the total returns of the indices do not.

Shareholder Fee Example

Fund shareholders may incur two types of costs: (1) transaction costs, including sales charges (loads) on purchase payments and redemption/exchange fees; and (2) ongoing costs, including management fees; distribution and service (12b-1) fees; and other fund expenses. This example is intended to help you understand your ongoing costs (in dollars) of investing in your fund and to compare these costs with the ongoing cost of investing in other mutual funds. As a shareholder in the underlying American Century Investments funds, your fund will indirectly bear its pro rata share of the expenses incurred by the underlying funds. These expenses are not included in the fund’s annualized expense ratio or the expenses paid during the period. These expenses are, however, included in the effective expenses paid during the period.

The example is based on an investment of $1,000 made at the beginning of the period and held for the entire period from August 1, 2012 to January 31, 2013.

Actual Expenses

The table provides information about actual account values and actual expenses for each class. You may use the information, together with the amount you invested, to estimate the expenses that you paid over the period. First, identify the share class you own. Then simply divide your account value by $1,000 (for example, an $8,600 account value divided by $1,000 = 8.6), then multiply the result by the number under the heading “Expenses Paid During Period” to estimate the expenses you paid on your account during this period.

If you hold Investor Class shares of any American Century Investments fund, or Institutional Class shares of the American Century Diversified Bond Fund, in an American Century Investments account (i.e., not a financial intermediary or retirement plan account), American Century Investments may charge you a $12.50 semiannual account maintenance fee if the value of those shares is less than $10,000. We will redeem shares automatically in one of your accounts to pay the $12.50 fee. In determining your total eligible investment amount, we will include your investments in all personal accounts (including American Century Investments Brokerage accounts) registered under your Social Security number. Personal accounts include individual accounts, joint accounts, UGMA/UTMA accounts, personal trusts, Coverdell Education Savings Accounts and IRAs (including traditional, Roth, Rollover, SEP-, SARSEP- and SIMPLE-IRAs), and certain other retirement accounts. If you have only business, business retirement, employer-sponsored or American Century Investments Brokerage accounts, you are currently not subject to this fee. If you are subject to the Account Maintenance Fee, your account value could be reduced by the fee amount.

Hypothetical Example for Comparison Purposes

The table also provides information about hypothetical account values and hypothetical expenses based on the actual expense ratio of each class of your fund and an assumed rate of return of 5% per year before expenses, which is not the actual return of a fund’s share class. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in your fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transactional costs, such as sales charges (loads) or redemption/exchange fees. Therefore, the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds. In addition, if these transactional costs were included, your costs would have been higher.

(1)

Expenses are equal to the class’s annualized expense ratio listed in the table above, multiplied by the average account value over the period, multiplied by 184, the number of days in the most recent fiscal half-year, divided by 365, to reflect the one-half year period. The fees and expenses of the underlying American Century Investments funds in which the fund invests are not included in the class’s annualized expense ratio.

(2)

Effective expenses reflect the sum of expenses borne directly by the class plus the fund’s pro rata share of the weighted average expense ratio of the underlying funds in which it invests. The effective annualized expense ratio combines the class’s annualized expense ratio and the annualized weighted average expense ratio of the underlying funds. The annualized weighted average expense ratio of the underlying funds for the one-half year period reflects the actual expense ratio of each underlying fund from its most recent shareholder report, annualized and weighted for the fund’s relative average investment therein during the period.

(3)	Other expenses, which include the fees and expenses of the fund’s independent directors and its legal counsel, as well as interest, did not exceed 0.005%.

Notes to Financial Statements

JANUARY 31, 2013 (UNAUDITED)

1. Organization

American Century Asset Allocation Portfolios, Inc. (the corporation) is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company and is organized as a Maryland corporation. LIVESTRONG Income Portfolio, LIVESTRONG 2015 Portfolio, LIVESTRONG 2020 Portfolio, LIVESTRONG 2025 Portfolio, LIVESTRONG 2030 Portfolio, LIVESTRONG 2035 Portfolio, LIVESTRONG 2040 Portfolio, LIVESTRONG 2045 Portfolio, LIVESTRONG 2050 Portfolio and LIVESTRONG 2055 Portfolio (collectively, the funds) are ten funds in a series issued by the corporation. The funds operate as “fund of funds,” meaning substantially all of the funds’ assets will be invested in other funds in the American Century Investments family of funds (the underlying funds). Each fund’s assets are allocated among underlying funds that represent major asset classes, including equity securities (stocks), fixed-income securities (bonds) and cash-equivalent instruments (money markets). The underlying funds are not permitted to invest in securities issued by companies assigned the Global Industry Classification Standard (GICS) for the tobacco industry. The funds are diversified as defined under the 1940 Act. Additionally, the underlying funds are generally diversified and so indirectly provide broad exposure to a large number of securities. The funds will assume the risks associated with their underlying funds. The investment objective of LIVESTRONG Income Portfolio is to seek current income. Capital appreciation is a secondary objective. The investment objectives of the nine target-year LIVESTRONG Portfolios are to seek the highest total return consistent with their respective asset mix. The funds pursue their objectives by investing in underlying funds that represent a variety of asset classes and investment styles. For each fund with a target-year, the target asset mix will be adjusted over time to become more conservative. In general, as the target-year approaches, the allocation to stocks will decrease and the allocation to bonds and money market instruments will increase. When a fund reaches its most conservative planned target asset allocation, which is expected to occur on approximately November 30 of the year before the target year, its target asset mix will become fixed and will match that of LIVESTRONG Income Portfolio.

The funds offer the Investor Class, the Institutional Class, the A Class, the C Class and the R Class. The A Class may incur an initial sales charge. The A Class and C Class may be subject to a contingent deferred sales charge. The share classes differ principally in their respective sales charges and distribution and shareholder servicing expenses and arrangements. The Institutional Class is made available to institutional shareholders or through financial intermediaries whose clients do not require the same level of shareholder and administrative services as shareholders of other classes. As a result, the Institutional Class is not charged an administrative fee.

2. Significant Accounting Policies

The following is a summary of significant accounting policies consistently followed by the funds in preparation of their financial statements. The financial statements are prepared in conformity with accounting principles generally accepted in the United States of America, which may require management to make certain estimates and assumptions at the date of the financial statements. Actual results could differ from these estimates.

Investment Valuations — The funds determine the fair value of their investments and compute their net asset value per share as of the close of regular trading (usually 4 p.m. Eastern time) on the New York Stock Exchange (NYSE) on each day the NYSE is open. Investments in the underlying funds are valued at their reported net asset value.

Security Transactions — Security transactions are accounted for as of the trade date. Net realized gains and losses are determined on the identified cost basis, which is also used for federal income tax purposes.

Investment Income — Income and capital gain distributions, if any, from the underlying funds are recorded as of the ex-dividend date. Long-term capital gain distributions, if any, from the underlying funds are a component of net realized gain (loss).

Expenses — The expenses included in the accompanying financial statements reflect the expenses of each fund and do not include any expenses associated with the underlying funds.

Income Tax Status — It is each fund’s policy to distribute substantially all net investment income and net realized gains to shareholders and to otherwise qualify as a regulated investment company under provisions of the Internal Revenue Code. LIVESTRONG Income Portfolio, LIVESTRONG 2015 Portfolio, LIVESTRONG 2020 Portfolio, LIVESTRONG 2025 Portfolio, LIVESTRONG 2030 Portfolio, LIVESTRONG 2035 Portfolio, LIVESTRONG 2040 Portfolio, LIVESTRONG 2045 Portfolio, and LIVESTRONG 2050 Portfolio are no longer subject to examination by tax authorities for years prior to 2009. All tax years for LIVESTRONG 2055 Portfolio remain subject to examination by authorities. At this time, management believes there are no uncertain tax positions which, based on their technical merit, would not be sustained upon examination and for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. Accordingly, no provision has been made for federal or state income taxes.

Multiple Class — All shares of each fund represent an equal pro rata interest in the net assets of the class to which such shares belong, and have identical voting, dividend, liquidation and other rights and the same terms and conditions, except for class specific expenses and exclusive rights to vote on matters affecting only individual classes. Income, non-class specific expenses, and realized and unrealized capital gains and losses of the funds are allocated to each class of shares based on their relative net assets.

Distributions to Shareholders — Distributions from net investment income, if any, are generally declared and paid quarterly for LIVESTRONG Income Portfolio. Distributions from net investment income, if any, are generally declared and paid annually for the nine target-date LIVESTRONG Portfolios. Distributions from net realized gains, if any, are generally declared and paid annually for all funds.

Indemnifications — Under the corporation’s organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the funds. In addition, in the normal course of business, the funds enter into contracts that provide general indemnifications. The maximum exposure under these arrangements is unknown as this would involve future claims that may be made against a fund. The risk of material loss from such claims is considered by management to be remote.

3. Fees and Transactions with Related Parties

Administrative Fees — The corporation has entered into an agreement with American Century Investment Management, Inc. (ACIM), under which ACIM provides the funds with shareholder services in exchange for an administrative fee (the fee). The fee is computed and accrued daily based on each class’s daily net assets and paid monthly in arrears. The rate of the fee for the Investor Class, A Class, C Class and R Class is 0.20%. There is no administrative fee for the Institutional Class.

Distribution and Service Fees — The Board of Directors has adopted a separate Master Distribution and Individual Shareholder Services Plan for each of the A Class, C Class and R Class (collectively the plans), pursuant to Rule 12b-1 of the 1940 Act. The plans provide that the A Class will pay American Century Investment Services, Inc. (ACIS) an annual distribution and service fee of 0.25%. The plans provide that the C Class will pay ACIS an annual distribution and service fee of 1.00%, of which 0.25% is paid for individual shareholder services and 0.75% is paid for distribution services. The plans provide that the R Class will pay ACIS an annual distribution and service fee of 0.50%. The fees are computed and accrued daily based on each class’s daily net assets and paid monthly in arrears. These fees are used to pay financial intermediaries for distribution and individual shareholder services. Fees incurred under the plans during the six months ended January 31, 2013 are detailed in the Statement of Operations.

Acquired Fund Fees and Expenses — Each fund will indirectly realize its pro rata share of the fees and expenses of the underlying funds in which it invests. These fees and expenses are already reflected in the valuation of the underlying funds.

Related Parties — Certain officers and directors of the corporation are also officers and/or directors of American Century Companies, Inc. (ACC). The corporation’s investment advisor, ACIM, the corporation’s distributor, ACIS, and the corporation’s transfer agent, American Century Services, LLC are wholly owned, directly or indirectly, by ACC. The directors of the corporation are also directors of some underlying funds and therefore those underlying funds may be deemed to be under common control with the corporation. The officers of the corporation are also officers of all the underlying funds. ACIM serves as the investment advisor for the underlying funds.

4. Investment Transactions

7. Investments in Underlying Funds

As of January 31, 2013, the funds, in aggregate, owned 100% of the total outstanding shares of the underlying NT Core Equity Plus Fund, NT Diversified Bond Fund, NT Emerging Markets Fund, NT Equity Growth Fund, NT Growth Fund, NT International Growth Fund, NT Large Company Value Fund, NT Mid Cap Value Fund, NT Small Company Fund and NT Vista Fund.

8. Fair Value Measurements

The funds’ securities valuation process is based on several considerations and may use multiple inputs to determine the fair value of the positions held by the funds. In conformity with accounting principles generally accepted in the United States of America, the inputs used to determine a valuation are classified into three broad levels as follows:

•	Level 1 valuation inputs consist of unadjusted quoted prices in an active market for identical securities;

•	Level 2 valuation inputs consist of direct or indirect observable market data (including quoted prices for similar securities, evaluations of subsequent market events, interest rates, prepayment speeds, credit risk, etc.); or

•	Level 3 valuation inputs consist of unobservable data (including a fund’s own assumptions).

The level classification is based on the lowest level input that is significant to the fair valuation measurement. The valuation inputs are not necessarily an indication of the risks associated with investing in these securities or other financial instruments.

As of period end, the funds’ investment securities were classified as Level 1. The Schedule of Investments provides additional information on the funds’ portfolio holdings.

9. Federal Tax Information

The book-basis character of distributions made during the year from net investment income or net realized gains may differ from their ultimate characterization for federal income tax purposes. These differences reflect the differing character of certain income items and net realized gains and losses for financial statement and tax purposes, and may result in reclassification among certain capital accounts on the financial statements.

As of January 31, 2013, the components of investments for federal income tax purposes were as follows:

	LIVESTRONG Income Portfolio		LIVESTRONG 2015 Portfolio		LIVESTRONG 2020 Portfolio		LIVESTRONG 2025 Portfolio		LIVESTRONG 2030 Portfolio

Gross tax appreciation of investments		$142,553,454		$58,749,853		$89,234,009		$25,693,628		$1,547,807
Gross tax depreciation of investments		—		—		—		—		(24,232	)

The difference between book-basis and tax-basis cost and unrealized appreciation (depreciation) is attributable primarily to the tax deferral of losses on wash sales.

Additional Information

Retirement Account Information

As required by law, distributions you receive from certain IRAs are subject to federal income tax withholding, unless you elect not to have withholding apply. Tax will be withheld on the total amount withdrawn even though you may be receiving amounts that are not subject to withholding, such as nondeductible contributions. In such case, excess amounts of withholding could occur. You may adjust your withholding election so that a greater or lesser amount will be withheld.

If you don’t want us to withhold on this amount, you must notify us to not withhold the federal income tax. You may notify us in writing or in certain situations by telephone or through other electronic means. For systematic withdrawals, your withholding election will remain in effect until revoked or changed by filing a new election. You have the right to revoke your election at any time.

Remember, even if you elect not to have income tax withheld, you are liable for paying income tax on the taxable portion of your withdrawal. If you elect not to have income tax withheld or you don’t have enough income tax withheld, you may be responsible for payment of estimated tax. You may incur penalties under the estimated tax rules if your withholding and estimated tax payments are not sufficient. You can reduce or defer the income tax on a distribution by directly or indirectly rolling such distribution over to another IRA or eligible plan. You should consult your tax advisor for additional information.

State tax will be withheld if, at the time of your distribution, your address is within one of the mandatory withholding states and you have federal income tax withheld (or as otherwise required by state law). State taxes will be withheld from your distribution in accordance with the respective state rules.

Distributions you receive from 403(b), 457 and qualified plans are subject to special tax and withholding rules. Your plan administrator or plan sponsor is required to provide you with a special tax notice explaining those rules at the time you request a distribution. If applicable, federal and/or state taxes may be withheld from your distribution amount.

President’s Letter

Jonathan Thomas

Dear Investor:

“Risk-On” Rebound After Second-Quarter Slump in 2012

Sincerely,

Jonathan Thomas

President and Chief Executive Officer

American Century Investments

Independent Chairman’s Letter

Don Pratt

Dear Fellow Shareholders,

The independent directors’ rationale for this decision is provided in detail in this, or in a previous, report. However, there are several highlights that should be of interest to all shareholders.

•	Fund performance and client service continue to be rated among the industry’s best.

•	Target date and other asset allocation products continue to successfully gather assets and industry acclaim.

•	Compliance programs continue to function successfully with no issues impacting shareholder interests.

•	Fees were found to be within an acceptable competitive range, with minor fee waivers being negotiated on five funds.

Overall it was a very positive review for the American Century Investments mutual funds during a challenging market environment.

Best personal regards,

Don Pratt

Data presented reflect past performance. Past performance is no guarantee of future results. Current performance may be higher or lower than the performance shown. Investment return and principal value will fluctuate, and redemption value may be more or less than original cost. To obtain performance data current to the most recent month end, please call 1-800-345-2021 or visit americancentury.com. The performance of the portfolios is dependent on the performance of their underlying American Century Investments funds, and will assume the risks associated with these funds. The risks will vary according to each portfolio’s asset allocation, and the risk level assigned to each portfolio is intended to reflect the relative short-term price volatility among the funds in each.

Data assumes reinvestment of dividends and capital gains, and none of the charts reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. Returns for the indices are provided for comparison. The fund’s total returns include operating expenses that reduce returns, while the total returns of the indices do not.

Notes to Financial Statements

JANUARY 31, 2013 (UNAUDITED)

1. Organization

American Century Asset Allocation Portfolios, Inc. (the corporation) is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company and is organized as a Maryland corporation. The corporation is authorized to issue 3,000,000,000 shares. One Choice Portfolio: Very Conservative (Very Conservative), One Choice Portfolio: Conservative (Conservative), One Choice Portfolio: Moderate (Moderate), One Choice Portfolio: Aggressive (Aggressive), and One Choice Portfolio: Very Aggressive (Very Aggressive) (collectively, the funds) are five funds in a series issued by the corporation. The funds operate as “fund of funds,” meaning that substantially all of the funds’ assets will be invested in other funds in the American Century Investments family of funds (the underlying funds). Each fund’s assets are allocated among underlying funds that represent major asset classes, including equity securities (stocks), fixed-income securities (bonds) and cash-equivalent instruments (money markets). The funds are diversified as defined under the 1940 Act. Additionally, the underlying funds are generally diversified and so indirectly provide broad exposure to a large number of securities. The funds will assume the risks associated with their underlying funds. The funds’ investment objectives are to seek the highest total return consistent with their respective asset mix. The funds pursue their objectives by investing in underlying funds that represent a variety of asset classes and investment styles. Generally, more conservative funds emphasize investments in bonds and cash equivalents while more aggressive funds emphasize investments in stocks.

2. Significant Accounting Policies

Expenses — The expenses included in the accompanying financial statements reflect the expenses of each fund and do not include any expenses associated with the underlying funds.

Income Tax Status — It is each fund’s policy to distribute substantially all net investment income and net realized gains to shareholders and to otherwise qualify as a regulated investment company under provisions of the Internal Revenue Code. The funds are no longer subject to examination by tax authorities for years prior to 2009. At this time, management believes there are no uncertain tax positions which, based on their technical merit, would not be sustained upon examination and for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. Accordingly, no provision has been made for federal or state income taxes.

Distributions to Shareholders — Distributions from net investment income, if any, are generally declared and paid quarterly for Very Conservative, Conservative, and Moderate. Distributions from net investment income, if any, are generally declared and paid annually for Aggressive and Very Aggressive. Distributions from net realized gains, if any, are generally declared and paid annually for all funds.

3. Fees and Transactions with Related Parties

Administrative Fees — The corporation’s investment advisor, American Century Investment Management, Inc. (ACIM), does not receive an administrative fee for services provided to the funds.

Related Parties — Certain officers and directors of the corporation are also officers and/or directors of American Century Companies, Inc. (ACC). The corporation’s investment advisor, ACIM, the corporation’s distributor, American Century Investment Services, Inc., and the corporation’s transfer agent, American Century Services, LLC are wholly owned, directly or indirectly, by ACC. The directors of the corporation are also directors of some underlying funds and therefore those underlying funds may be deemed to be under common control with the corporation. The officers of the corporation are also officers of all the underlying funds. ACIM serves as the investment advisor for the underlying funds.

4. Investment Transactions

Investment transactions for the six months ended January 31, 2013 were as follows:

	Very Conservative	Conservative	Moderate	Aggressive	Very Aggressive
Purchases	$102,961,896	$69,429,357	$83,588,401	$171,296,032	$23,201,507

•	Level 3 valuation inputs consist of unobservable data (including a fund’s own assumptions).

As of period end, the funds’ investment securities were classified as Level 1. The Schedule of Investments provides additional information on the funds’ portfolio holdings.

8. Federal Tax Information

As of January 31, 2013, the components of investments for federal income tax purposes were as follows:

	Very Conservative	Conservative	Moderate
Federal tax cost of investments	$303,242,233	$586,027,227	$855,617,837
Gross tax appreciation of investments	$22,750,448	$63,898,783	$120,716,700

Net tax appreciation (depreciation) of investments	$22,750,419	$63,898,783	$120,716,700
