OUR MESSAGE TO YOU

We have the privilege of providing you with the annual report for
LIVESTRONG(TM) Portfolios from American Century Investments® for the 12 months
ended July 31, 2007, to help you monitor your investment.

2007 has been an eventful year for the financial markets and for us. While the
markets experienced subprime-related turbulence, we've been working to secure
a smooth executive leadership transition. In our semiannual report, we
announced the promotion of former international equity chief investment
officer (CIO) Enrique Chang to overall CIO. One of Enrique's immediate
challenges was to hire a new international equity CIO, which he accomplished
in May when Mark On joined us from AXA Rosenberg. Enrique also hired Steve
Lurito from MUUS Asset Management LLC in July to fill our vacant U.S. growth
equity CIO position.

We also announced the promotion of Jonathan Thomas to chief executive officer,
effective March 1. In June, Jonathan hired Barry Fink, who came to us from
Morgan Stanley, as chief operating officer. This completed our leadership
transition, and helped make it possible for my son, Jim Stowers III, to step
down from the American Century Companies, Inc. (ACC) board of directors at the
end of July to focus on his new business ventures. I remain co-chair of the
ACC board with Richard Brown, who has been on the board since 1998 and also
co-chairs the Stowers Institute for Medical Research board.

Jim's recent departure, after he relinquished his executive leadership and
investment management responsibilities in early 2005, reflects his comfort
with the firm's direction and new leadership. As with Jim before them, we've
been energized by the skills and experience brought to the leadership team by
Jonathan, Enrique, Barry, Mark, and Steve. They've already had a positive
impact on the development and management of the products and services we take
pride in delivering to you.

(2) In September of 2006, LIVESTRONG Portfolios changed their fixed income
benchmark from the Lehman Brothers U.S. Aggregate Index to the Citigroup US
Broad Investment-Grade Bond Index. The fund's investment advisor believes this
index better represents the fixed income portion of the fund's portfolio
composition.

The Russell 3000 Index represents approximately 98% of the investable U.S.
equity market and provides a broad measure of equity performance. The Lehman
Brothers U.S. Aggregate Index and the Citigroup US Broad Investment-Grade Bond
Index represent 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 each LIVESTRONG
Portfolio's asset allocations as of July 31, 2007.)

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 LIVESTRONG Portfolios is dependent on
the performance of their underlying American Century 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.
International investing involves special risks, such as political instability
and currency fluctuations. Investing in emerging markets may accentuate these
risks.

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.

PORTFOLIO COMMENTARY
LIVESTRONG Portfolios

PERFORMANCE SUMMARY

All five LIVESTRONG Portfolios enjoyed strong results for the year ended July

double-digit gains for stocks, both in the U.S. and overseas, as well as solid
gains in the bond market.

Because of LIVESTRONG Portfolios' strategic exposure to the various asset
classes, a review of the financial markets helps explain much of their
performance.

STOCK MARKET REVIEW

U.S. stocks produced robust returns during the past year despite an economic
slowdown brought on by a sharp decline in the housing market. Corporate
earnings growth decelerated -- ending a streak of double-digit quarterly
earnings growth for the S&P 500 Index that began in 2002 -- but continued to
outshine expectations. In addition, heavy merger activity provided support for
stocks thanks to a deluge of leveraged buy-outs from private equity firms.

Although the broad stock indexes returned more than 15% for the one-year
period, the market hit a couple of speed bumps over the last six months.
Stocks stumbled in late February, mirroring a drop in the Chinese stock
market, but rebounded quickly in early March. The market grew choppy in the
last two months and ended the period with a sharp decline as higher energy
prices and deteriorating credit conditions -- sparked by problems in the
subprime lending industry -- weighed on investor confidence.

Mid-cap stocks led the market's advance, followed by large-cap shares, while
small-cap issues lagged. After trailing value stocks for six consecutive
years, growth-oriented issues outperformed by a wide margin over the past 12
months.

LIVESTRONG Portfolios

International stocks outperformed the domestic market as improving global
economic conditions and a declining U.S. dollar boosted foreign markets. The
top performers were emerging markets, with Latin America generating the
largest gains. Among developed markets, European bourses posted the best
returns, while Japanese shares lagged as a burgeoning economic recovery in the
country appeared to stall.

BOND MARKET REVIEW

The U.S. bond market delivered solid gains during the period as interest rates
declined overall. The Federal Reserve (the Fed) held short-term interest rates
steady throughout the one-year period as economic activity decelerated while
inflation remained above the Fed's comfort level, largely because of
stubbornly high energy prices.

Although bond yields fluctuated in response to economic data, energy price
volatility, and subprime lending woes, yields were little changed overall
between July 2006 and June 2007. In July 2007, however, a "flight to quality"
resulting from a worsening credit environment led to a sizable decline in
yields, producing higher bond prices.

LIVESTRONG Portfolios

High-yield corporate bonds were the best performers for the one-year period,
though they underperformed in the flight to quality late in the period. In
contrast, Treasury bonds benefited the most from the flight to quality, and as
a result they generated the best returns among investment-grade bond sectors.

Foreign bonds also produced positive results as the U.S. dollar fell against
most major currencies (with the notable exception of the Japanese yen).
Overseas bond returns were positive despite stronger economic growth that led
central banks in many countries to raise interest rates.

LIVESTRONG Portfolios

PORTFOLIO PERFORMANCE

Each LIVESTRONG Portfolio is a "fund of funds" that invests in other American
Century mutual funds to achieve its investment objective and target asset
allocation. (See page 8 for the specific underlying fund allocations for each
LIVESTRONG Portfolio.)

Most of the equity funds in LIVESTRONG Portfolios registered double-digit
gains for the one-year period. NT Emerging Markets was the top performer,
advancing sharply thanks to surging markets in developing countries. NT
International Growth also produced a healthy gain for the period. Among
domestic holdings, NT Vista was the best performer, reflecting the
outperformance of mid-cap stocks. The LIVESTRONG Portfolios' large-cap growth
component, which includes NT Growth and NT Equity Growth, also fared well. The
weakest performer was Real Estate, which posted a fractionally positive return
overall in the wake of a double-digit decline in the last few months of the
period. Real Estate stocks fell as the worsening environment for debt
financing reduced the likelihood of private equity buyouts in the sector.

The performance of LIVESTRONG Portfolios' fixed-income funds were in line with
the broad returns of the bond market. International Bond was the best
performer, followed by NT Diversified Bond and High Yield. Inflation-Adjusted
Bond posted the lowest returns among the LIVESTRONG Portfolios' fixed-income
holdings, but it outperformed over the last three months of the period as
energy prices rose. Premium Money Market provided principal protection and a
return that outpaced the three-month U.S. Treasury bill.

STARTING POINT FOR NEXT REPORTING PERIOD

Although corporate earnings have held up better than expected, the dollar's
decline has played a key role -- 49% of the sales for the companies in the S&P
500 come from foreign operations, and a weaker dollar makes those overseas
revenues worth more at home. Going forward, however, we expect the economic
slowdown of the past year to take its toll on corporate profits as consumer
spending succumbs to higher gas prices and declining mortgage equity
withdrawals.

Market volatility has increased considerably in recent months, and we expect
that to continue going forward. This environment reinforces the need for
diversified investments like LIVESTRONG Portfolios.

SHAREHOLDER FEE EXAMPLES (UNAUDITED)

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 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 February 1, 2007 to July 31, 2007.

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 fund, or
Institutional Class shares of the American Century Diversified Bond Fund, in
an American Century account (i.e., not a financial intermediary or retirement
plan account), American Century 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 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 Brokerage accounts, you are currently not subject to this
fee. We will not charge the fee as long as you choose to manage your accounts
exclusively online. 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 181, 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 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%.

(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 181, 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 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

JULY 31, 2007

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION -- American Century Asset Allocation Portfolios, Inc. (the
corporation) is registered under the Investment Company Act of 1940 (the 1940
Act), as amended, as an open-end management investment company. LIVESTRONG
Income Portfolio, LIVESTRONG 2015 Portfolio, LIVESTRONG 2025 Portfolio,
LIVESTRONG 2035 Portfolio and LIVESTRONG 2045 Portfolio (collectively, the
funds) are five 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 family of funds (the
underlying funds). Because the funds directly invest in a relatively small
number of underlying funds, they are not diversified as defined by the 1940
Act. However, the underlying funds are generally diversified and so indirectly
provide broad exposure to a large number of securities. The investment
objective of LIVESTRONG Income Portfolio is to seek current income. Capital
appreciation is a secondary objective. The investment objectives of the four
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 annually in a step-like fashion. 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
following is a summary of the funds' significant accounting policies.

MULTIPLE CLASS -- The funds are authorized to issue the Investor Class,
Institutional Class, Advisor Class and R Class. The share classes differ
principally in their respective distribution and shareholder servicing
expenses and arrangements. 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.

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 NT Diversified Bond, NT Emerging Markets, NT Equity
Growth, NT Growth, NT International Growth, NT Large Company Value, NT Mid Cap
Value, NT Small Company and NT Vista funds are not permitted to invest in
securities issues by companies assigned the Global Industry Classification
Standard (GICS) for the tobacco industry. A brief description of each of the
underlying funds follows.

DOMESTIC EQUITY FUNDS

NT EQUITY GROWTH seeks long-term capital growth. It uses a quantitative
investment strategy to construct an optimized portfolio drawn primarily from
the 1,500 largest publicly traded U.S. companies without regard to dividend
yield.

NT GROWTH seeks long-term capital growth. It uses a growth investment strategy
and generally invests in larger U.S. companies.

NT LARGE COMPANY VALUE seeks long-term capital growth with income as a
secondary objective. It uses a value investment strategy and invests primarily
in larger U.S. companies.

NT MID CAP VALUE seeks long-term capital growth with income as a secondary
objective. It uses a value investment strategy and invests primarily in
mid-sized U.S. companies.

NT SMALL COMPANY seeks long-term capital growth. It uses a quantitative
investment strategy and invests primarily in smaller U.S. companies.

NT VISTA seeks long-term capital growth. It uses a growth investment strategy
and generally invests in medium-sized and smaller U.S. companies.

REAL ESTATE seeks high total investment return through a combination of
capital appreciation and current income. It invests primarily in equity
securities issued by real estate investment trusts and companies engaged in
the real estate industry.


- ------
25


INTERNATIONAL EQUITY FUNDS

NT EMERGING MARKETS seeks capital growth. It uses a growth investment strategy
and invests primarily in securities of companies located in emerging market
countries and companies that derive a significant portion of their business
from emerging market countries.

NT INTERNATIONAL GROWTH seeks capital growth. It uses a growth investment
strategy and invests primarily in securities of companies located in developed
countries other than the United States.

DOMESTIC FIXED INCOME FUNDS

HIGH-YIELD seeks high current income by investing in a diversified portfolio
of high-yield corporate bonds and other debt securities. As a second
objective, the fund seeks capital appreciation, but only when consistent with
its primary objective of managing current income.

INFLATION-ADJUSTED BOND seeks to provide total return and inflation protection
consistent with investment in inflation-indexed securities.

NT DIVERSIFIED BOND seeks a high level of income by investing primarily in
high- and medium-grade non-money market debt securities. These securities,
which may be payable in U.S. or foreign currencies, may include corporate
bonds and notes, government securities and securities backed by mortgages or
other assets.

INTERNATIONAL FIXED INCOME FUNDS

INTERNATIONAL BOND seeks high total return by investing in high-quality,
non-dollar-denominated government and corporate debt securities outside the
United States.

MONEY MARKET FUNDS

PREMIUM MONEY MARKET seeks to earn the highest level of current income while
preserving the value of shareholder investments by investing in high-quality,
cash-equivalent securities.

SECURITY VALUATIONS -- Investments in the underlying funds are valued at their
reported net asset value. The underlying funds have specific valuation
policies. If an event occurs after the value of a security was established but
before the net asset value per share of an underlying fund was determined that
was likely to materially change the net asset value of the underlying fund,
that security would be valued as determined in accordance with procedures
adopted by the Board of Directors/Trustees. If the underlying fund determines
that the market price of a portfolio security is not readily available, or
that the valuation methods mentioned above do not reflect the security's fair
value, such security is valued as determined by, or in accordance with
procedures adopted by, the Board of Directors/Trustees or its designee if such
determination would materially impact an underlying fund's net asset value.
Certain other circumstances may cause the underlying fund to use alternative
procedures to value a security such as: a security has been declared in
default; trading in a security has been halted during the trading day; or
there is a foreign market holiday and no trading will commence.

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 the 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. At this time, management has not identified any uncertain tax
positions that would materially impact the financial statements. Accordingly,
no provision has been made for federal or state income taxes. Interest and
penalties associated with any federal or state income tax obligations, if any,
are recorded as interest expense.


- ------
26


DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded on
the ex-dividend date. Distributions from net investment income, if any, are
generally declared and paid quarterly for LIVESTRONG Income Portfolios.
Distributions from net investment income, if any, are generally declared and
paid annually for the four 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 funds' maximum exposure under these arrangements is
unknown as this would involve future claims that may be made against the
funds. The risk of material loss from such claims is considered by management
to be remote.

USE OF ESTIMATES -- 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.

2. FEES AND TRANSACTIONS WITH RELATED PARTIES

ADMINISTRATIVE FEES -- The corporation has entered into a Management 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 the daily net
assets of each specific class of shares of each fund and paid monthly in
arrears. The rate of the fee for the Investor Class, Advisor Class and R Class
of the funds is 0.20%. There is no administrative fee for the Institutional
Class.

DISTRIBUTION FEES -- The Board of Directors has adopted a separate Master
Distribution and Individual Shareholder Services Plan for the Advisor Class
and R Class (collectively, the plans), pursuant to Rule 12b-1 of the 1940 Act.
The plans provide that the Advisor Class will pay American Century Investment
Services, Inc. (ACIS) an annual distribution and service fee of 0.25%. 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 for distribution services and shareholder services. Fees incurred under
the plans during the year ended July 31, 2007, are detailed in the Statement
of Operations.

MANAGEMENT FEES -- 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, and, as a group, controlling stockholders of
American Century Companies, Inc. (ACC), the parent of the corporation's
investment advisor, ACIM, the distributor of the corporation, ACIS, and the
corporation's transfer agent, American Century Services, LLC. 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 or American Century Global Investment Management, Inc.,
a wholly-owned subsidiary of ACIM, serves as the investment advisor for the
underlying funds.

6. INVESTMENTS IN UNDERLYING FUNDS

The funds do not invest in the underlying funds for the purpose of exercising
management or control; however, investments by the funds within their
investment strategies may represent a significant portion of the underlying
funds' net assets. As of July 31, 2007, the following LIVESTRONG Portfolios
owned 25% or more of the total outstanding shares of the underlying funds:

                                        LIVESTRONG                     LIVESTRONG

As of July 31, 2007, the funds, in aggregate, owned 100% of the total
outstanding shares of the underlying NT Diversified Bond, NT Emerging Markets,
NT Equity Growth, NT Growth, NT International Growth, NT Large Company Value,
NT Mid Cap Value, NT Small Company and NT Vista funds.

7. RISK FACTORS

Some of the underlying funds invest in foreign securities, which are generally
riskier than U.S. securities. As a result, the funds are subject to foreign
risk, meaning that political events (such as civil unrest, national elections
and imposition of exchange controls), social, and economic events (such as
labor strikes and rising inflation), and natural disasters occurring in a
country where the funds invest could cause the funds' investments in that
country to experience gains or losses. Investing in emerging markets may
accentuate these risks.

8. FEDERAL TAX INFORMATION

The tax character of distributions paid during the years ended July 31, 2007
and July 31, 2006 were as follows:

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 July 31, 2007, the components of distributable earnings on a tax-basis
and the federal tax cost of investments were as follows:

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.

9. RECENTLY ISSUED ACCOUNTING STANDARDS

In June 2006, the Financial Accounting Standards Board (FASB) issued
Interpretation No. 48, "Accounting for Uncertainty in Income Taxes -- an
Interpretation of FASB Statement No. 109" (FIN 48). FIN 48 establishes a
minimum threshold for financial statement recognition of the benefit of
positions taken in filing tax returns (including whether an entity is taxable
in a particular jurisdiction), and requires certain expanded tax disclosures.
FIN 48 is effective for fiscal years beginning after December 15, 2006, and is
to be applied to all open tax years as of the date of effectiveness.
Management has concluded that the adoption of FIN 48 will not materially
impact the financial statements.

The FASB issued Statement of Financial Accounting Standards No. 157, "Fair
Value Measurements" (FAS 157), in September 2006, which is effective for
fiscal years beginning after November 15, 2007. FAS 157 defines fair value,
establishes a framework for measuring fair value and expands the required
financial statement disclosures about fair value measurements. Management is
currently evaluating the impact that adopting FAS 157 will have on the
financial statement disclosures.

(3) Total return assumes reinvestment of net investment income and capital
gains distributions, if any. Total returns for periods less than one year are
not annualized. The total return of the classes may not precisely reflect the
class expense differences because of the impact of calculating the net asset
values to two decimal places. If net asset values were calculated to three
decimal places, the total return differences would more closely reflect the
class expense differences. The calculation of net asset values to two decimal
places is made in accordance with SEC guidelines and does not result in any
gain or loss of value between one class and another.

(4) Ratio of operating expenses to average net assets does not include any
expenses of the underlying funds.

(5) Annualized.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders,
American Century Asset Allocation Portfolios, Inc.:

We have audited the accompanying statements of assets and liabilities,
including the schedules of investments, of LIVESTRONG Income Portfolio,
LIVESTRONG 2015 Portfolio, LIVESTRONG 2025 Portfolio, LIVESTRONG 2035
Portfolio, and LIVESTRONG 2045 Portfolio (collectively the "Funds"), five of
the mutual funds comprising American Century Asset Allocation Portfolios, Inc.
as of July 31, 2007, and the related statements of operations for the year
then ended, the statements of changes in net assets for each of the two years
in the period then ended, and the financial highlights for the periods
presented. These financial statements and financial highlights are the
responsibility of the Funds' management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. The Funds are not required to have, nor were we engaged to
perform, an audit of their internal control over financial reporting. Our
audits included consideration of internal control over financial reporting as
a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Funds' internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on
a test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. Our procedures included confirmation of securities owned as of
July 31, 2007, by correspondence with the transfer agent. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the Funds comprising American Century Asset Allocation Portfolios, Inc. as
of July 31, 2007, the results of their operations for the year then ended, the
changes in their net assets for each of the two years in the period then
ended, and the financial highlights for the periods presented, in conformity
with accounting principles generally accepted in the United States of America.

MANAGEMENT

The individuals listed below serve as directors or officers of the funds. Each
director serves until his or her successor is duly elected and qualified or
until he or she retires. Mandatory retirement age for independent directors is
72. Those listed as interested directors are "interested" primarily by virtue
of their engagement as directors and/or officers of, or ownership interest in,
American Century Companies, Inc. (ACC) or its wholly owned, direct or
indirect, subsidiaries, including the funds' investment advisor, American
Century Investment Management, Inc. (ACIM); the funds' principal underwriter,
American Century Investment Services, Inc. (ACIS); and the funds' transfer
agent, American Century Services, LLC (ACS).

The other directors (more than three-fourths of the total number) are
independent; that is, they have never been employees, directors or officers
of, and have no financial interest in, ACC or any of its wholly owned, direct
or indirect, subsidiaries, including ACIM, ACIS, and ACS. The directors serve
in this capacity for seven registered investment companies in the American
Century family of funds.

All persons named as officers of the funds also serve in similar capacities
for the other 14 investment companies advised by ACIM or American Century
Global Investment Management, Inc. (ACGIM), a wholly owned subsidiary of ACIM,
unless otherwise noted. Only officers with policy-making functions are listed.
No officer is compensated for his or her service as an officer of the funds.
The listed officers are interested persons of the funds and are appointed or
re-appointed on an annual basis.

APPROVAL OF MANAGEMENT AGREEMENTS
LIVESTRONG Portfolios

Under Section 15(c) of the Investment Company Act, contracts for investment
advisory services are required to be reviewed, evaluated and approved by a
majority of a fund's independent directors or trustees (the "Directors") each
year. At American Century, this process is referred to as the "15(c) Process."
As a part of this process, the board reviews fund performance, shareholder
services, audit and compliance information, and a variety of other reports
from the advisor concerning fund operations. In addition to this annual
review, the board of directors oversees and evaluates on a continuous basis at
its quarterly meetings the nature and quality of significant services
performed by the advisor, fund performance, audit and compliance information,
and a variety of other reports relating to fund operations. The board, or
committees of the board, also holds special meetings as needed.

Under a Securities and Exchange Commission rule, each fund is required to
disclose in its annual or semiannual report, as appropriate, the material
factors and conclusions that formed the basis for the board's approval or
renewal of any advisory agreements within the fund's most recently completed
fiscal half-year period.

ANNUAL CONTRACT REVIEW PROCESS

As part of the annual 15(c) Process undertaken during the most recent fiscal
half-year period, the Directors reviewed extensive data and information
compiled by the advisor and certain independent providers of evaluative data
(the "15(c) Providers") concerning LIVESTRONG Income Portfolio, LIVESTRONG
2015 Portfolio, LIVESTRONG 2025 Portfolio, LIVESTRONG 2035 Portfolio and
LIVESTRONG 2045 Portfolio (the "funds") and the services provided to the funds
under the management agreement. The information considered and the discussions
held at the meetings included, but were not limited to:

* the nature, extent and quality of investment management, shareholder
services and other services provided to the funds under the management
agreement;

* reports on the advisor's activities relating to the wide range of programs
and services the advisor provides to the funds and their shareholders on a
routine and non-routine basis;

* data comparing the cost of owning the funds to the cost of owning similar
funds;

* data comparing the funds' performance to appropriate benchmarks and/or a
peer group of other mutual funds with similar investment objectives and
strategies;

* financial data showing the profitability of the funds to the advisor and the
overall profitability of the advisor; and

* data comparing services provided and charges to other investment management
clients of the advisor.

In keeping with its practice, the funds' board of directors held two regularly
scheduled meetings and one special meeting to review and discuss the
information provided by the advisor and to complete its negotiations with the
advisor regarding the renewal of the management agreement. The board also had
the benefit of the advice of its independent counsel throughout the period.

64


FACTORS CONSIDERED

The Directors considered all of the information provided by the advisor, the
15(c) Providers, and the board's independent counsel, and evaluated such
information for each fund for which the board has responsibility. The
Directors did not identify any single factor as being all-important or
controlling, and each Director may have attributed different levels of
importance to different factors. In deciding to renew the agreement under the
terms ultimately determined by the board to be appropriate, the Directors'
decision was based on the following factors.

NATURE, EXTENT AND QUALITY OF SERVICES -- GENERALLY. Under the management
agreement, the advisor is responsible for providing or arranging for all
services necessary for the operation of the funds. The board noted that under
the management agreement, the advisor provides or arranges at its own expense
a wide variety of services including:

* fund construction and design

* portfolio security selection

* initial capitalization/funding

* securities trading

* custody of fund assets

* daily valuation of the funds' portfolio

* shareholder servicing and transfer agency, including shareholder
confirmations, recordkeeping and communications

* legal services

* regulatory and portfolio compliance

* financial reporting

* marketing and distribution

The Directors noted that many of these services have expanded over time both
in terms of quantity and complexity in response to shareholder demands,
competition in the industry and the changing regulatory environment. In
performing their evaluation, the Directors considered information received in
connection with the annual review, as well as information provided on an
ongoing basis at their regularly scheduled board and committee meetings.

INVESTMENT MANAGEMENT SERVICES. The nature of the investment management
services provided is quite complex and allows fund shareholders access to
professional money management, instant diversification of their investments
within an asset class, the opportunity to easily diversify among asset
classes, and liquidity. In evaluating investment performance, the board
expects the advisor to manage the funds in accordance with their investment
objectives and approved strategies. In providing these services, the advisor
utilizes teams of investment professionals (portfolio managers, analysts,
research assistants, and securities traders) who require extensive information
technology, research, training, compliance and other systems to conduct their
business.

At each quarterly meeting the Directors review investment performance
information for the funds, together with comparative information for
appropriate benchmarks and peer groups of funds managed similarly to the
funds. The Directors also review detailed performance information during the
15(c) Process comparing the funds' performance with that of similar funds not
managed by the advisor. If performance concerns are identified, the Directors
discuss with the advisor the reasons for such results (e.g., market
conditions, security selection) and any efforts being undertaken to improve
performance. LIVESTRONG Income Portfolio's performance for both the one- and
three-year periods was above the median for its peer group. LIVESTRONG 2015
Portfolio's and LIVESTRONG 2035 Portfolio's performance fell below the median
for both the one- and three-year periods during part of the past year.
LIVESTRONG 2025 Portfolio's performance fell below the median for the one-year
period and was equal to the median for the three-year period. LIVESTRONG 2045
Portfolio's performance was slightly below the median for the one-year period
and above the median for the three-year period. The board discussed the funds'
performance with the advisor and was satisfied with the efforts being
undertaken by the advisor.

SHAREHOLDER AND OTHER SERVICES. The advisor provides the funds with a
comprehensive package of transfer agency, shareholder, and other services. The
Directors review reports and evaluations of such services at their regular
quarterly meetings, including the annual meeting concerning contract review,
and reports to the board. These reports include, but are not limited to,
information regarding the operational efficiency and accuracy of the
shareholder and transfer agency services provided, staffing levels,
shareholder satisfaction (as measured by external as well as internal
sources), technology support, new products and services offered to fund
shareholders, securities trading activities, portfolio valuation services,
auditing services, and legal and operational compliance activities. Certain
aspects of shareholder and transfer agency service level efficiency and the
quality of securities trading activities are measured by independent third
party providers and are presented in comparison to other fund groups not
managed by the advisor.

COSTS OF SERVICES PROVIDED AND PROFITABILITY TO THE ADVISOR. The advisor
provides detailed information concerning its cost of providing various
services to the funds, its profitability in managing the funds, its overall
profitability, and its financial condition. The Directors have reviewed with
the advisor the methodology used to prepare this financial information. This
financial information regarding the advisor is considered in order to evaluate
the advisor's financial condition, its ability to continue to provide services
under the management agreement, and the reasonableness of the current
management fee.

ETHICS OF THE ADVISOR. The Directors generally consider the advisor's
commitment to providing quality services to shareholders and to conducting its
business ethically. They noted that the advisor's practices generally meet or
exceed industry best practices.

ECONOMIES OF SCALE. The Directors review reports provided by the advisor on
economies of scale for the complex as a whole and the year-over-year changes
in revenue, costs, and profitability. The Directors concluded that economies
of scale are difficult to measure and predict with precision, especially on a
fund-by-fund basis. This analysis is also complicated by the additional
services and content provided by the advisor and its reinvestment in its
ability to provide and expand those services. Accordingly, the Directors also
seek to evaluate economies of scale by reviewing other information, such as
year-over-year profitability of the advisor generally, the profitability of
its management of the funds specifically, the expenses incurred by the advisor
in providing various functions to the funds, and the breakpoint fees of
competitive funds


- ------
66


not managed by the advisor. The Directors believe the advisor is appropriately
sharing economies of scale through its competitive fee structure, fee
breakpoints as the funds increase in size, and through reinvestment in its
business to provide shareholders additional content and services.

COMPARISON TO OTHER FUNDS' FEES. The funds invest their non-cash assets
entirely in other American Century funds. The funds do not pay an investment
advisor fee to the advisor. Rather, each fund indirectly bears its pro rata
share of the expenses incurred by the underlying funds. Each of the underlying
funds pay the advisor a single, all-inclusive (or unified) management fee for
providing all services necessary for the management and operation of the
funds, other than brokerage expenses, taxes, interest, extraordinary expenses,
and the fees and expenses of the funds' independent directors (including their
independent legal counsel). Under the unified fee structure, the advisor is
responsible for providing all investment advisory, custody, audit,
administrative, compliance, recordkeeping, marketing and shareholder services,
or arranging and supervising third parties to provide such services. By
contrast, most other funds are charged a variety of fees, including an
investment advisory fee, a transfer agency fee, an administrative fee,
distribution charges and other expenses. Other than their investment advisory
fees and Rule 12b-1 distribution fees, all other components of the total fees
charged by these other funds may be increased without shareholder approval.
The board believes the unified fee structure is a benefit to fund shareholders
because it clearly discloses to shareholders the cost of owning fund shares,
and, since the unified fee cannot be increased without a vote of fund
shareholders, it shifts to the advisor the risk of increased costs of
operating the funds and provides a direct incentive to minimize administrative
inefficiencies. Part of the Directors' analysis of fee levels involves
reviewing certain evaluative data compiled by a 15(c) Provider comparing the
portion of the expenses incurred by the underlying funds to the total expense
ratio of other funds in the funds' peer group. The expenses of LIVESTRONG
Income Portfolio were in the lowest quartile of the total expense ratios of
its peer group. All other funds' expenses were above the median of the total
expense ratios of their respective peer groups.

COMPARISON TO FEES AND SERVICES PROVIDED TO OTHER CLIENTS OF THE ADVISOR. The
Directors also requested and received information from the advisor concerning
the nature of the services, fees, and profitability of its advisory services
to advisory clients other than the funds. They observed that these varying
types of client accounts require different services and involve different
regulatory and entrepreneurial risks than the management of the funds. The
Directors analyzed this information and concluded that the fees charged and
services provided to the funds were reasonable by comparison.

COLLATERAL BENEFITS DERIVED BY THE ADVISOR. The Directors reviewed information
from the advisor concerning collateral benefits it receives as a result of its
relationship with the funds. They concluded that the advisor's primary
business is managing mutual funds and it generally does not use fund or
shareholder information to generate profits in other lines of business, and
therefore does not derive any significant collateral benefits from them. The
Directors noted that the advisor receives proprietary research from
broker-dealers that execute fund portfolio transactions and concluded that
this research is likely to benefit fund shareholders. The Directors also
determined that the advisor is able to provide investment management services
to certain clients other than the funds, at least in part, due to its existing
infrastructure built to serve the fund complex. The Directors concluded,
however, that the assets of those other clients are not material to the
analysis and, in any event, are included with the assets of the funds to
determine breakpoints in the funds' fee schedule, provided they are managed
using the same investment team and strategy.


- ------
67


CONCLUSIONS OF THE DIRECTORS

As a result of this process, the independent directors, in the absence of
particular circumstances and assisted by the advice of legal counsel that is
independent of the advisor, taking into account all of the factors discussed
above and the information provided by the advisor concluded that the
investment management agreement between the funds and the advisor is fair and
reasonable in light of the services provided and should be renewed.

68


SHARE CLASS INFORMATION

Four classes of shares are authorized for sale by the funds: Investor Class,
Institutional Class, Advisor Class and R Class. The total expense ratio of
Institutional Class shares is lower than that of Investor Class shares; the
total expense ratios of the Advisor Class and R Class shares is higher than
that of Investor Class shares.

INVESTOR CLASS shares are available for purchase in two ways: 1) directly from
American Century without any commissions or other fees; or 2) through certain
financial intermediaries (such as banks, broker-dealers, insurance companies
and investment advisors), which may require payment of a transaction fee to
the financial intermediary.

INSTITUTIONAL CLASS shares are available to large investors such as
endowments, foundations, and retirement plans, and to financial intermediaries
serving these investors. This class recognizes the relatively lower cost of
serving institutional customers and others who invest at least $5 million ($3
million for endowments and foundations) in an American Century fund or at
least $10 million in multiple funds. In recognition of the larger investments
and account balances and comparatively lower transaction costs, the total
expense ratio of Institutional Class shares is 0.20% less than the total
expense ratio of Investor Class shares.

ADVISOR CLASS shares are sold primarily through institutions such as
investment advisors, banks, broker-dealers, insurance companies, and financial
advisors. Advisor Class shares are subject to a 0.25% annual Rule 12b-1
distribution and service fee. The total expense ratio of Advisor Class shares
is 0.25% higher than the total expense ratio of Investor Class shares.

R CLASS shares are sold primarily through employer-sponsored retirement plans
and through institutions such as investment advisors, banks, broker-dealers,
and insurance companies. R Class shares are subject to a 0.50% annual Rule
12b-1 distribution and service fee. The total expense ration of R Class shares
is 0.50% higher than the total expense ration of Investor Class shares.

All classes of shares represent a pro rata interest in the funds and generally
have the same rights and preferences.

ADDITIONAL INFORMATION

RETIREMENT ACCOUNT INFORMATION

As required by law, any distributions you receive from an IRA or certain
403(b), 457 and qualified plans [those not eligible for rollover to an IRA or
to another qualified plan] 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. Even if you plan to roll over the amount you
withdraw to another tax-deferred account, the withholding rate still applies
to the withdrawn amount unless we have received notice not to withhold federal
income tax prior to the withdrawal. You may notify us in writing or in certain
situations by telephone or through other electronic means. You have the right
to revoke your withholding election at any time and any election you make may
remain in effect until revoked by filing a new election.

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.

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. State taxes will be withheld from your distribution in
accordance with the respective state rules.

OUR MESSAGE TO YOU

We have the privilege of providing you with the annual report for the American
Century® One Choice Portfolios for the 12 months ended July 31, 2007, to help
you monitor your investment.

2007 has been an eventful year for the financial markets and for us. While the
markets experienced subprime-related turbulence, we've been working to secure
a smooth executive leadership transition. In our semiannual report, we
announced the promotion of former international equity chief investment
officer (CIO) Enrique Chang to overall CIO. One of Enrique's immediate
challenges was to hire a new international equity CIO, which he accomplished
in May when Mark On joined us from AXA Rosenberg. Enrique also hired Steve
Lurito from MUUS Asset Management LLC in July to fill our vacant U.S. growth
equity CIO position.

We also announced the promotion of Jonathan Thomas to chief executive officer,
effective March 1. In June, Jonathan hired Barry Fink, who came to us from
Morgan Stanley, as chief operating officer. This completed our leadership
transition, and helped make it possible for my son, Jim Stowers III, to step
down from the American Century Companies, Inc. (ACC) board of directors at the
end of July to focus on his new business ventures. I remain co-chair of the
ACC board with Richard Brown, who has been on the board since 1998 and also
co-chairs the Stowers Institute for Medical Research board.

Jim's recent departure, after he relinquished his executive leadership and
investment management responsibilities in early 2005, reflects his comfort
with the firm's direction and new leadership. As with Jim before them, we've
been energized by the skills and experience brought to the leadership team by
Jonathan, Enrique, Barry, Mark, and Steve. They've already had a positive
impact on the development and management of the products and services we take
pride in delivering to you.

(2) In September of 2006, the portfolios changed their fixed income index from

PORTFOLIO COMMENTARY
One Choice Portfolios

Portfolio Managers: Jeff Tyler and Irina Torelli

PERFORMANCE SUMMARY

All five of the One Choice Portfolios enjoyed strong results for the year
ended July 31, 2007. Returns ranged from 7.23% for One Choice: Very
Conservative to 21.87% for One Choice: Very Aggressive (see pages 2-5 for more
detailed performance information). The Portfolios' performance reflected
double-digit gains for stocks, both in the U.S. and overseas, as well as solid
gains in the bond market.

Because of the Portfolios' strategic exposure to the various asset classes, a
review of the financial markets helps explain much of their performance.

STOCK MARKET REVIEW

U.S. stocks produced robust returns during the past year despite an economic
slowdown brought on by a sharp decline in the housing market. Corporate
earnings growth decelerated -- ending a streak of double-digit quarterly
earnings growth for the S&P 500 Index that began in 2002 -- but continued to
outshine expectations. In addition, heavy merger activity provided support for
stocks thanks to a deluge of leveraged buy-outs from private equity firms.

Although the broad stock indexes returned more than 15% for the one-year
period, the market hit a couple of speed bumps over the last six months.
Stocks stumbled in late February, mirroring a drop in the Chinese stock
market, but rebounded quickly in early March. The market grew choppy in the
last two months and ended the period with a sharp decline as higher energy
prices and deteriorating credit conditions -- sparked by problems in the
subprime lending industry -- weighed on investor confidence.

Mid-cap stocks led the market's advance, followed by large-cap shares, while
small-cap issues lagged. After trailing value stocks for six consecutive
years, growth-oriented issues outperformed by a wide margin over the past 12
months.

International stocks outperformed the domestic market as improving global
economic conditions and a declining U.S. dollar boosted foreign markets. The
top performers were emerging markets, with Latin America generating the
largest gains. Among developed markets, European bourses posted the best
returns, while Japanese shares lagged as a burgeoning economic recovery in the
country appeared to stall.

BOND MARKET REVIEW

The U.S. bond market delivered solid gains during the period as interest rates
declined overall. The Federal Reserve (the Fed) held short-term interest rates
steady throughout the one-year period as economic activity decelerated while
inflation remained above the Fed's comfort level, largely because of
stubbornly high energy prices.

Although bond yields fluctuated in response to economic data, energy price
volatility, and subprime lending woes, yields were little changed overall
between July 2006 and June 2007. In July 2007, however, a "flight to quality"
resulting from a worsening credit environment led to a sizable decline in
yields, producing higher bond prices.

High-yield corporate bonds were the best performers for the one-year period,
though they underperformed in the flight to quality late in the period. In
contrast, Treasury bonds benefited the most from the flight to quality, and as
a result they generated the best returns among investment-grade bond sectors.

Foreign bonds also produced positive results as the U.S. dollar fell against
most major currencies (with the notable exception of the Japanese yen).
Overseas bond returns were positive despite stronger economic growth that led
central banks in many countries to raise interest rates.

One Choice Portfolios

PORTFOLIO PERFORMANCE

Each One Choice Portfolio is a "fund of funds" that invests in other American
Century mutual funds to achieve its investment objective and target asset
allocation. (See page 7 for the specific underlying fund allocations for each
One Choice Portfolio.)

With one exception, the equity funds in the One Choice Portfolios registered
double-digit gains for the one-year period. Emerging Markets was the top
performer, advancing sharply thanks to surging markets in developing
countries. International Growth also produced a healthy gain for the period.
Among domestic holdings, Vista was the best performer, reflecting the
outperformance of mid-cap stocks. The Portfolios' large-cap growth component,
which includes Growth and Equity Growth, also fared well. The exception was
Real Estate, which posted a fractionally positive return overall in the wake
of a double-digit decline in the last few months of the period. Real Estate
stocks fell as the worsening environment for debt financing reduced the
likelihood of private equity buyouts in the sector.

The performance of the Portfolios' fixed-income funds were in line with the
broad returns of the bond market. International Bond was the best performer,
followed by Diversified Bond and High-Yield. Prime Money Market provided
principal protection and a return that outpaced the three-month U.S. Treasury
bill.

One Choice Portfolios

PORTFOLIO STRATEGY

Each Portfolio has a "neutral" asset mix that remains constant, but we
typically make modest adjustments to each Portfolio's actual asset mix to add
value and improve the Portfolios' ability to meet their investment objectives.
Over the past year, we shifted to a slight overweight position in bonds and a
matching underweight position in stocks. This defensive posture reflected our
expectations for a softer economy, weaker corporate earnings, and a declining
U.S. dollar. In general, this positioning detracted modestly from overall
performance as stocks continued to outperform.

Within the equity component of the Portfolios, we remained overweight in
large-cap stocks, which tend to hold up better in a weaker economic
environment because of their relatively consistent cash flows, and underweight
in mid- and smaller-company issues. Results from this positioning were
generally positive -- our large-cap overweight helped as large-cap stocks
posted strong gains, and although our mid-cap underweight hurt as mid-cap
shares outperformed, we benefited from strong stock selection in this segment
of the market. We also moved back to a neutral position in mid-cap issues
toward the end of the period.

The overweight in fixed-income securities consisted entirely of a modest
position in international bonds, which was based on our expectations for a
declining dollar given weaker economic activity in the U.S. and expanding
economies overseas. Domestically, we held an underweight in corporate bonds, a
defensive position designed to protect against "event risk"-- the risk of a
leveraged buyout, share buyback, or special dividend that benefits
stockholders at the expense of bondholders. For the Portfolios that have
exposure to High-Yield, we moved to an underweight position in the last half
of the period as the yield gap between Treasury and high-yield bonds reached
historically narrow levels.

STARTING POINT FOR NEXT REPORTING PERIOD

Although corporate earnings have held up better than expected, the dollar's
decline has played a key role -- 49% of the sales for the companies in the S&P
500 come from foreign operations, and a weaker dollar makes those overseas
revenues worth more at home. Going forward, however, we expect the economic
slowdown of the past year to take its toll on corporate profits as consumer
spending succumbs to higher gas prices and declining mortgage equity
withdrawals.

Market volatility has increased considerably in recent months, and we expect
that to continue going forward. This environment reinforces our conservative
tactical positioning for the Portfolios -- slightly underweight in stocks and
a modest overweight in bonds.

SHAREHOLDER FEE EXAMPLES (UNAUDITED)

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 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 February 1, 2007 to July 31, 2007.

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 fund, or
Institutional Class shares of the American Century Diversified Bond Fund, in
an American Century account (i.e., not a financial intermediary or retirement
plan account), American Century 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 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 Brokerage accounts, you are currently not subject to this
fee. We will not charge the fee as long as you choose to manage your accounts
exclusively online. 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 fund's annualized expense ratio listed in the
table above, multiplied by the average account value over the period,
multiplied by 181, 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 funds in which the fund invests are not
included in the fund's annualized expense ratio.

(2) Effective expenses reflect the sum of expenses borne directly by the fund
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 fund'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

JULY 31, 2007

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION -- American Century Asset Allocation Portfolios, Inc. (the
corporation) is registered under the Investment Company Act of 1940 (the 1940
Act), as amended, as an open-end management investment company. 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 family of funds (the underlying funds). Because
the funds directly invest in a relatively small number of underlying funds,
they are not diversified as defined by the 1940 Act. However, the underlying
funds are generally diversified and so indirectly provide broad exposure to a
large number of securities. 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. The corporation is
authorized to issue 3,000,000,000 shares. The following is a summary of the
funds' significant accounting policies.

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). A brief description of each of the underlying funds follows.

DOMESTIC EQUITY FUNDS

EQUITY GROWTH seeks long-term capital growth. It uses a quantitative
investment strategy to construct an optimized portfolio drawn primarily from
the 1,500 largest publicly traded U.S. companies without regard to dividend
yield.

GROWTH seeks long-term capital growth. It uses a growth investment strategy
and generally invests in larger U.S. companies.

LARGE COMPANY VALUE seeks long-term capital growth with income as a secondary
objective. It uses a value investment strategy and invests primarily in larger
U.S. companies.

REAL ESTATE seeks high total investment return through a combination of
capital appreciation and current income. It invests primarily in equity
securities issued by real estate investment trusts and companies engaged in
the real estate industry.

SMALL COMPANY seeks long-term capital growth. It uses a quantitative
investment strategy and invests primarily in smaller U.S. companies.

VALUE seeks long-term capital growth with income as a secondary objective. It
uses a value investment strategy and invests primarily in U.S. companies of
all sizes.

VISTA seeks long-term capital growth. It uses a growth investment strategy and
generally invests in medium-sized and smaller U.S. companies.

DOMESTIC FIXED INCOME FUNDS

DIVERSIFIED BOND seeks a high level of income by investing primarily in high-
and medium-grade, non-money market debt securities. These securities, which
may be payable in U.S. or foreign currencies, may include corporate bonds and
notes, government securities and securities backed by mortgages or other
assets.

HIGH-YIELD seeks high current income by investing in a diversified portfolio
of high-yield corporate bonds and other debt securities. As a second
objective, the fund seeks capital appreciation, but only when consistent with
its primary objective of maximizing current income.

INTERNATIONAL FIXED INCOME FUNDS

INTERNATIONAL BOND seeks high total return by investing in high-quality,
non-dollar-denominated government and corporate debt securities outside the
United States.

MONEY MARKET FUNDS

PRIME MONEY MARKET seeks to earn the highest level of current income while
preserving the value of shareholder investments by investing in high-quality,
cash-equivalent securities.

SECURITY VALUATIONS -- Investments in the underlying funds are valued at their
reported net asset value. The underlying funds have specific valuation
policies. If an event occurs after the value of a security was established but
before the net asset value per share of an underlying fund was determined that
was likely to materially change the net asset value of the underlying fund,
that security would be valued as determined in accordance with procedures
adopted by the Board of Directors/ Trustees. If the underlying fund determines
that the market price of a portfolio security is not readily available, or
that the valuation methods mentioned above do not reflect the security's fair
value, such security is valued as determined by, or in accordance with
procedures adopted by, the Board of Directors/ Trustees or its designee if
such determination would materially impact an underlying fund's net asset
value. Certain other circumstances may cause the underlying fund to use
alternative procedures to value a security such as: a security has been
declared in default; trading in a security has been halted during the trading
day; or there is a foreign market holiday and no trading will commence.

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).

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. At this time, management has not identified any uncertain tax
positions that would materially impact the financial statements. Accordingly,
no provision has been made for federal or state income taxes. Interest and
penalties associated with any federal or state income tax obligations, if any,
are recorded as interest expense.

DISTRIBUTIONS TO SHAREHOLDERS -- Distributions to shareholders are recorded on
the ex-dividend date. 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.

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 funds' maximum exposure under these arrangements is
unknown as this would involve future claims that may be made against the
funds. The risk of material loss from such claims is considered by management
to be remote.


- ------
23


USE OF ESTIMATES -- 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.

2. FEES AND TRANSACTIONS WITH RELATED PARTIES

MANAGEMENT FEES -- The corporation's investment advisor, American Century
Investment Management, Inc. (ACIM), does not receive an administrative fee for
services provided to the funds. 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, and, as a group, controlling stockholders of
American Century Companies, Inc. (ACC), the parent of the corporation's
investment advisor, ACIM, the distributor of the corporation, American Century
Investment Services, Inc., and the corporation's transfer agent, American
Century Services, LLC. 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 or American Century Global
Investment Management, Inc., a wholly-owned subsidiary of ACIM, serves as the
investment advisor for the underlying funds.

5. INVESTMENTS IN UNDERLYING FUNDS

The funds do not invest in the underlying funds for the purpose of exercising
management or control; however, investments by the funds within their
investment strategies may represent a significant portion of the underlying
funds' net assets. As of July 31, 2007, Moderate owned 25% of the total
outstanding shares of Diversified Bond Fund. As of July 31, 2007, the funds,
in aggregate, owned 53% of Diversified Bond Fund.

6. RISK FACTORS

Some of the underlying funds invest in foreign securities, which are generally
riskier than U.S. securities. As a result, the funds are subject to foreign
risk, meaning that political events (such as civil unrest, national elections
and imposition of exchange controls), social and economic events (such as
labor strikes and rising inflation), and natural disasters occurring in a
country where the funds invest could cause the funds' investments in that
country to experience gain or losses. Investing in emerging markets may
accentuate these risks.

7. FEDERAL TAX INFORMATION

The tax character of distributions paid during the years ended July 31, 2007
and July 31, 2006 were as follows:

Long-term capital gains        $466,050     $26,412

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 July 31, 2007, the components of distributable earnings on a tax-basis
and the federal tax cost of investments were as follows:

                              Very                                                            Very

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.

8. RECENTLY ISSUED ACCOUNTING STANDARDS

In June 2006, the Financial Accounting Standards Board (FASB) issued
Interpretation No. 48, "Accounting for Uncertainty in Income Taxes - an
Interpretation of FASB Statement No. 109" (FIN 48). FIN 48 establishes a
minimum threshold for financial statement recognition of the benefit of
positions taken in filing tax returns (including whether an entity is taxable
in a particular jurisdiction), and requires certain expanded tax disclosures.
FIN 48 is effective for fiscal years beginning after December 15, 2006, and is
to be applied to all open tax years as of the date of effectiveness.
Management has concluded that the adoption of FIN 48 will not materially
impact the financial statements.

The FASB issued Statement of Financial Accounting Standards No. 157, "Fair
Value Measurements" (FAS 157), in September 2006, which is effective for
fiscal years beginning after November 15, 2007. FAS 157 defines fair value,
establishes a framework for measuring fair value and expands the required
financial statement disclosures about fair value measurements. Management is
currently evaluating the impact that adopting FAS 157 will have on the
financial statement disclosures.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders,
American Century Asset Allocation Portfolios, Inc.:

We have audited the accompanying statements of assets and liabilities,
including the schedules of investments, of One Choice Portfolio: Very
Conservative, One Choice Portfolio: Conservative, One Choice Portfolio:
Moderate, One Choice Portfolio: Aggressive, and One Choice Portfolio: Very
Aggressive (collectively the "Funds"), five of the mutual funds comprising
American Century Asset Allocation Portfolios, Inc. as of July 31, 2007, and
the related statements of operations for the year then ended, the statements
of changes in net assets for each of the two years in the period then ended,
and the financial highlights for the periods presented. These financial
statements and financial highlights are the responsibility of the Funds'
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements and financial highlights are free of material
misstatement. The Funds are not required to have, nor were we engaged to
perform, an audit of their internal control over financial reporting. Our
audits included consideration of internal control over financial reporting as
a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Funds' internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on
a test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. Our procedures included confirmation of securities owned as of
July 31, 2007, by correspondence with the transfer agent. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the Funds comprising American Century Asset Allocation Portfolios, Inc. as
of July 31, 2007, the results of their operations for the year then ended, the
changes in their net assets for each of the two years in the period then
ended, and the financial highlights for the periods presented, in conformity
with accounting principles generally accepted in the United States of America.

MANAGEMENT

The individuals listed below serve as directors or officers of the funds. Each
director serves until his or her successor is duly elected and qualified or
until he or she retires. Mandatory retirement age for independent directors is
72. Those listed as interested directors are "interested" primarily by virtue
of their engagement as directors and/or officers of, or ownership interest in,
American Century Companies, Inc. (ACC) or its wholly owned, direct or
indirect, subsidiaries, including the funds' investment advisor, American
Century Investment Management, Inc. (ACIM); the funds' principal underwriter,
American Century Investment Services, Inc. (ACIS); and the funds' transfer
agent, American Century Services, LLC (ACS).

The other directors (more than three-fourths of the total number) are
independent; that is, they have never been employees, directors or officers
of, and have no financial interest in, ACC or any of its wholly owned, direct
or indirect, subsidiaries, including ACIM, ACIS, and ACS. The directors serve
in this capacity for seven registered investment companies in the American
Century family of funds.

All persons named as officers of the funds also serve in similar capacities
for the other 14 investment companies advised by ACIM or American Century
Global Investment Management, Inc. (ACGIM), a wholly owned subsidiary of ACIM,
unless otherwise noted. Only officers with policy-making functions are listed.
No officer is compensated for his or her service as an officer of the funds.
The listed officers are interested persons of the funds and are appointed or
re-appointed on an annual basis.

APPROVAL OF MANAGEMENT AGREEMENT
One Choice Portfolios

Under Section 15(c) of the Investment Company Act, contracts for investment
advisory services are required to be reviewed, evaluated and approved by a
majority of a fund's independent directors or trustees (the "Directors") each
year. At American Century, this process is referred to as the "15(c) Process."
As a part of this process, the board reviews fund performance, shareholder
services, audit and compliance information, and a variety of other reports
from the advisor concerning fund operations. In addition to this annual
review, the board of directors oversees and evaluates on a continuous basis at
its quarterly meetings the nature and quality of significant services
performed by the advisor, fund performance, audit and compliance information,
and a variety of other reports relating to fund operations. The board, or
committees of the board, also holds special meetings as needed.

Under a Securities and Exchange Commission rule, each fund is required to
disclose in its annual or semiannual report, as appropriate, the material
factors and conclusions that formed the basis for the board's approval or
renewal of any advisory agreements within the fund's most recently completed
fiscal half-year period.

ANNUAL CONTRACT REVIEW PROCESS

As part of the annual 15(c) Process undertaken during the most recent fiscal
half-year period, the Directors reviewed extensive data and information
compiled by the advisor and certain independent providers of evaluative data
(the "15(c) Providers") concerning One Choice Portfolio: Very Aggressive, One
Choice Portfolio: Aggressive, One Choice Portfolio: Moderate, One Choice
Portfolio: Conservative and One Choice Portfolio: Very Conservative (the
"funds") and the services provided to the funds under the management
agreement. The information considered and the discussions held at the meetings
included, but were not limited to:

* the nature, extent and quality of investment management, shareholder
services and other services provided to the funds under the management
agreement;

* reports on the advisor's activities relating to the wide range of programs
and services the advisor provides to the funds and its shareholders on a
routine and non-routine basis;

* data comparing the cost of owning the fund to the cost of owning similar
funds;

* data comparing the funds' performance to appropriate benchmarks and/or a
peer group of other mutual funds with similar investment objectives and
strategies;

* financial data showing the profitability of the fund to the advisor and the
overall profitability of the advisor; and

* data comparing services provided and charges to other investment management
clients of the advisor.

In keeping with its practice, the funds' board of directors held two regularly
scheduled meetings and one special meeting to review and discuss the
information provided by the advisor and to complete its negotiations with the
advisor regarding the renewal of the management agreement. The board also had
the benefit of the advice of its independent counsel throughout the period.

FACTORS CONSIDERED

The Directors considered all of the information provided by the advisor, the
15(c) Providers, and the board's independent counsel, and evaluated such
information for each fund for which the board has responsibility. The
Directors did not identify any single factor as being all-important or
controlling, and each Director may have attributed different levels of
importance to different factors. In deciding to renew the agreement under the
terms ultimately determined by the board to be appropriate, the Directors'
decision was based on the following factors.

NATURE, EXTENT AND QUALITY OF SERVICES - GENERALLY. Under the management
agreement, the advisor is responsible for providing or arranging for all
services necessary for the operation of the funds. The board noted that under
the management agreement, the advisor provides or arranges at its own expense
a wide variety of services including:

* fund construction and design

* portfolio security selection

* initial capitalization/funding

* securities trading

* custody of fund assets

* daily valuation of the funds' portfolio

* shareholder servicing and transfer agency, including shareholder
confirmations, recordkeeping and communications

* legal services

* regulatory and portfolio compliance

* financial reporting

* marketing and distribution

The Directors noted that many of these services have expanded over time both
in terms of quantity and complexity in response to shareholder demands,
competition in the industry and the changing regulatory environment. In
performing their evaluation, the Directors considered information received in
connection with the annual review, as well as information provided on an
ongoing basis at their regularly scheduled board and committee meetings.

INVESTMENT MANAGEMENT SERVICES. The nature of the investment management
services provided is quite complex and allows fund shareholders access to
professional money management, instant diversification of their investments
within an asset class, the opportunity to easily diversify among asset
classes, and liquidity. In evaluating investment performance, the board
expects the advisor to manage the funds in accordance with its investment
objectives and approved strategies. In providing these services, the advisor
utilizes teams of investment professionals (portfolio managers, analysts,
research assistants, and securities traders) who require extensive information
technology, research, training, compliance and other systems to conduct their
business. At each quarterly meeting the Directors review investment
performance information

for the funds, together with comparative information for appropriate
benchmarks and peer groups of funds managed similarly to the funds. The
Directors also review detailed performance information during the 15(c)
Process comparing the funds' performance with that of similar funds not
managed by the advisor. If performance concerns are identified, the Directors
discuss with the advisor the reasons for such results (e.g., market
conditions, security selection) and any efforts being undertaken to improve
performance. One Choice Portfolio: Very Conservative's performance fell below
the median for both the one and three year periods during part of the past
year. The board discussed the fund's performance with the advisor and was
satisfied with the efforts being undertaken by the advisor. Each other funds'
performance for both the one and three year periods was above the median for
its respective peer groups.

SHAREHOLDER AND OTHER SERVICES. The advisor provides the funds with a
comprehensive package of transfer agency, shareholder, and other services. The
Directors review reports and evaluations of such services at their regular
quarterly meetings, including the annual meeting concerning contract review,
and reports to the board. These reports include, but are not limited to,
information regarding the operational efficiency and accuracy of the
shareholder and transfer agency services provided, staffing levels,
shareholder satisfaction (as measured by external as well as internal
sources), technology support, new products and services offered to fund
shareholders, securities trading activities, portfolio valuation services,
auditing services, and legal and operational compliance activities. Certain
aspects of shareholder and transfer agency service level efficiency and the
quality of securities trading activities are measured by independent third
party providers and are presented in comparison to other fund groups not
managed by the advisor.

COSTS OF SERVICES PROVIDED AND PROFITABILITY TO THE ADVISOR. The advisor
provides detailed information concerning its cost of providing various
services to the funds, its profitability in managing the funds, its overall
profitability, and its financial condition. The Directors have reviewed with
the advisor the methodology used to prepare this financial information. This
financial information regarding the advisor is considered in order to evaluate
the advisor's financial condition, its ability to continue to provide services
under the management agreement, and the reasonableness of the current
management fee.

ETHICS OF THE ADVISOR. The Directors generally consider the advisor's
commitment to providing quality services to shareholders and to conducting its
business ethically. They noted that the advisor's practices generally meet or
exceed industry best practices.

ECONOMIES OF SCALE. The Directors review reports provided by the advisor on
economies of scale for the complex as a whole and the year-over-year changes
in revenue, costs, and profitability. The Directors concluded that economies
of scale are difficult to measure and predict with precision, especially on a
fund-by-fund basis. This analysis is also complicated by the additional
services and content provided by the advisor and its reinvestment in its
ability to provide and expand those services. Accordingly, the Directors also
seek to evaluate economies of scale by reviewing other information, such as
year-over-year profitability of the advisor generally, the profitability of
its management of the funds specifically, the expenses incurred by the advisor
in providing various functions to the funds, and the breakpoint fees of
competitive funds not managed by the advisor. The Directors believe the
advisor is appropriately sharing economies of scale through its competitive
fee structure, fee breakpoints as the fund increases in size, and through
reinvestment in its business to provide shareholders additional content and
services.


- ------
42


COMPARISON TO OTHER FUNDS' FEES. The funds invest their non-cash assets
entirely in other American Century funds. The funds do not pay an investment
advisor fee to the advisor. Rather, each fund indirectly bears its pro rata
share of the expenses incurred by the underlying funds. Each of the underlying
funds pay the advisor a single, all-inclusive (or unified) management fee for
providing all services necessary for the management and operation of the
funds, other than brokerage expenses, taxes, interest, extraordinary expenses,
and the fees and expenses of the funds' independent directors (including their
independent legal counsel). Under the unified fee structure, the advisor is
responsible for providing all investment advisory, custody, audit,
administrative, compliance, recordkeeping, marketing and shareholder services,
or arranging and supervising third parties to provide such services. By
contrast, most other funds are charged a variety of fees, including an
investment advisory fee, a transfer agency fee, an administrative fee,
distribution charges and other expenses. Other than their investment advisory
fees and Rule 12b-1 distribution fees, all other components of the total fees
charged by these other funds may be increased without shareholder approval.
The board believes the unified fee structure is a benefit to fund shareholders
because it clearly discloses to shareholders the cost of owning fund shares,
and, since the unified fee cannot be increased without a vote of fund
shareholders, it shifts to the advisor the risk of increased costs of
operating the funds and provides a direct incentive to minimize administrative
inefficiencies. Part of the Directors' analysis of fee levels involves
reviewing certain evaluative data compiled by a 15(c) Provider comparing the
portion of the expenses incurred by the underlying funds to the total expense
ratio of other funds in the funds' peer group. The expenses of One Choice
Portfolio: Very Aggressive, One Choice Portfolio: Conservative and One Choice
Portfolio: Very Conservative were in the lowest quartile of the total expense
ratios of their peer groups. The expenses of One Choice Portfolio: Aggressive
and One Choice Portfolio: Moderate were below the median of the total expense
ratios of their peer groups.

COMPARISON TO FEES AND SERVICES PROVIDED TO OTHER CLIENTS OF THE ADVISOR. The
Directors also requested and received information from the advisor concerning
the nature of the services, fees, and profitability of its advisory services
to advisory clients other than the funds. They observed that these varying
types of client accounts require different services and involve different
regulatory and entrepreneurial risks than the management of the funds. The
Directors analyzed this information and concluded that the fees charged and
services provided to the funds were reasonable by comparison.

COLLATERAL BENEFITS DERIVED BY THE ADVISOR. The Directors reviewed information
from the advisor concerning collateral benefits it receives as a result of its
relationship with the funds. They concluded that the advisor's primary
business is managing mutual funds and it generally does not use the fund or
shareholder information to generate profits in other lines of business, and
therefore does not derive any significant collateral benefits from them. The
Directors noted that the advisor receives proprietary research from broker
dealers that execute fund portfolio transactions and concluded that this
research is likely to benefit fund shareholders. The Directors also determined
that the advisor is able to provide investment management services to certain
clients other than the funds, at least in part, due to its existing
infrastructure built to serve the fund complex. The Directors concluded,
however, that the assets of those other clients are not material to the
analysis and, in any event, are included with the assets of the funds to
determine breakpoints in the funds' fee schedule, provided they are managed
using the same investment team and strategy.

CONCLUSIONS OF THE DIRECTORS

As a result of this process, the independent directors, in the absence of
particular circumstances and assisted by the advice of legal counsel that is
independent of the advisor, taking into account all of the factors discussed
above and the information provided by the advisor concluded that the
investment management agreement between the funds and the advisor is fair and
reasonable in light of the services provided and should be renewed.

ADDITIONAL INFORMATION

RETIREMENT ACCOUNT INFORMATION

As required by law, any distributions you receive from an IRA or certain
403(b), 457 and qualified plans [those not eligible for rollover to an IRA or
to another qualified plan] 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. Even if you plan to roll over the amount you
withdraw to another tax-deferred account, the withholding rate still applies
to the withdrawn amount unless we have received notice not to withhold federal
income tax prior to the withdrawal. You may notify us in writing or in certain
situations by telephone or through other electronic means. You have the right
to revoke your withholding election at any time and any election you make may
remain in effect until revoked by filing a new election.

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.

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. State taxes will be withheld from your distribution in
accordance with the respective state rules.

         investment adviser,  its parent company,  and any entity controlled by,
         or under common  control  with the  investment  adviser  that  provides
         ongoing services to the registrant,  if the engagement relates directly
         to the operations and financial reporting of the registrant.

(e)(2)   All services  described in each of  paragraphs  (b) through (d) of this
         Item were pre-approved  before the engagement by the registrant's audit
         committee pursuant to paragraph (c)(7)(i)(A) of Rule 2-01 of Regulation
         S-X.  Consequently,  none of such services were required to be approved
         by the audit committee pursuant to paragraph (c)(7)(i)(C).

(f)      The  percentage  of  hours  expended  on  the  principal   accountant's
         engagement to audit the registrant's  financial statements for the most
         recent fiscal year that were  attributed  to work  performed by persons
         other than the principal  accountant's  full-time,  permanent employees
         was less than 50%.

(g)      The aggregate non-audit fees billed by the registrant's  accountant for
         services  rendered to the registrant,  and rendered to the registrant's
         investment  adviser  (not  including  any  sub-adviser  whose  role  is
         primarily portfolio management and is subcontracted with or overseen by
         another investment adviser), and any entity controlling, controlled by,
         or under common control with the adviser that provides ongoing services
         to the  registrant  for  each  of the  last  two  fiscal  years  of the
         registrant were as follows:

         FY 2006:  $179,156
         FY 2007:  $174,483

(h)      The  registrant's  investment  adviser and accountant have notified the
         registrant's  audit  committee  of all  non-audit  services  that  were
         rendered by the registrant's  accountant to the registrant's investment
         adviser,  its parent  company,  and any entity  controlled by, or under
         common  control with the investment  adviser that provides  services to
         the  registrant,  which  services were not required to be  pre-approved
         pursuant to paragraph  (c)(7)(ii) of Rule 2-01 of  Regulation  S-X. The
         notification  provided to the  registrant's  audit  committee  included
         sufficient  details  regarding such services to allow the  registrant's
         audit  committee  to  consider  the  continuing   independence  of  its
         principal accountant.
