                 For the six-month period ended Jan. 31, 2007

[THE FOLLOWING TABLE WAS REPRESENTED AS A BAR CHART IN THE PRINTED MATERIAL.]

Lipper Large-Cap Core Funds Index(2)                                   +13.75%

(1)   The Standard & Poor's 500 Index (S&P 500 Index), an unmanaged index of
      common stocks, is frequently used as a general measure of market
      performance. The index reflects reinvestment of all distributions and
      changes in market prices.

(2)   The Lipper Large-Cap Core Funds Index includes the 30 largest large-cap
      core funds tracked by Lipper Inc. The index's returns include net
      reinvested dividends. The Fund's performance is currently measured
      against this index for purposes of determining the performance incentive
      adjustment.



The performance information shown represents past performance and is not a
guarantee of future results. The investment return and principal value of your
investment will fluctuate so that your shares, when redeemed, may be worth
more or less than their original cost. Current performance may be lower or
higher than the performance information shown. You may obtain performance
information current to the most recent month-end by contacting your financial
institution or visiting riversource.com/funds.

The 5.75% sales charge applicable to Class A shares of the Fund is not
reflected in the bar chart. If reflected, returns would be lower than those
shown. The performance of other classes may vary from that shown because of
differences in expenses.

The indices do not reflect the effects of sales charges, expenses (excluding
Lipper) and taxes.

RIVERSOURCE DISCIPLINED EQUITY FUND - 2007 SEMIANNUAL REPORT 7


QUESTIONS & ANSWERS WITH PORTFOLIO MANAGEMENT

Below, Portfolio Managers Dimitris Bertsimas and Gina Mourtzinou discuss
RiverSource Disciplined Equity Fund's positioning and results for the six
months ended Jan. 31, 2007.

Q:    How did RiverSource Disciplined Equity Fund perform for the annual
      period?

A:    RiverSource Disciplined Equity Fund's Class A shares (excluding sales
      charge) returned 14.15% for the six months ended Jan. 31, 2007. The Fund
      outperformed the Standard & Poor's 500 Index (S&P 500 Index), which
      gained 13.75%, as well as the Lipper Large-Cap Core Funds Index,
      representing the Fund's peer group, which returned 13.17%, for the same
      period.

Q:    What factors most significantly affected the Fund's performance?

A:    The performance of the Fund is highly correlated with the performance of
      our three quantitative investment models (momentum, value and quality).
      The three models are combined through a sophisticated optimization
      process that trades-off expected excess return and risk.

      For the six-month reporting period, the momentum and the value model
      outperformed the S&P 500 Index, with the momentum model taking the
      strong lead. Meanwhile, the quality model underperformed, relative to
      the S&P 500 Index.

      FOR THE SIX-MONTH REPORTING PERIOD, THE MOMENTUM AND THE VALUE MODEL
      OUTPERFORMED THE S&P 500 INDEX, WITH THE MOMENTUM MODEL TAKING THE
      STRONG LEAD.

      Contributing to performance was our significant positions in
      telecommunication services and consumer discretionary, two of the
      best-performing sectors over the period. On the flipside, the Fund's
      position in energy, about 13.6% of the Fund, hurt performance since
      energy was the worst-performing sector of the S&P 500 Index over the
      six-month period.

      Overall, the Fund's performance can be attributed to strong stock
      selection. In terms of stock selection, our energy stocks performed very
      well, even though the energy sector did poorly. Moreover, our stock
      selection within telecommunication services was very strong, making this
      sector the best performing sector of the Fund's portfolio. We also had
      very strong selection within financials, health care and utilities.
      Conversely, our stock selections within

QUESTIONS & ANSWERS

      consumer discretionary and consumer staples detracted. Finally we
      maintained a position in information technology that was below that of
      the S&P 500 Index, and this hurt performance, especially since our stock
      selection within information technology was not especially strong.

      IN TERMS OF STOCK SELECTION, OUR ENERGY STOCKS PERFORMED VERY WELL, EVEN
      THOUGH THE ENERGY SECTOR DID POORLY.

      Our risk modeling also contributed to the Fund's strong performance
      relative to the S&P 500 Index and Lipper peer group. Our risk models
      limit the size of individual holdings, as well as sector and industry
      allocations, relative to the S&P 500 Index. For example, the portfolio's
      weightings by sector and industry can never be more than 6% overweighted
      or underweighted relative to the S&P 500 Index. We also apply additional
      risk controls that impose constraints on market capitalization, price,
      quality, turnover, transaction costs and other variables.

      Finally, the Fund has maintained a small exposure to international
      markets through iShares MSCI EAFE Index Fund and this also helped
      performance. The Fund's position in iShares MSCI EAFE Index Fund was
      established based on a separate asset allocation model.

      Individual holdings that contributed the most to the Fund's return
      include: AT&T and Verizon Communications, two telecom stocks picked
      primarily by the value model; pharmaceutical company Merck & Co., which
      was favored by all three models (i.e., momentum, value and quality);
      financial companies Merrill Lynch & Co., a momentum model pick; and
      Fannie Mae, primarily a value model selection. Finally, Chevron and
      Exxon Mobil, two energy companies that are selections from the value and
      quality models, were strong performers for the period.

      Detractors from performance include Schlumberger, an energy company and
      a momentum model pick that posted losses of more that 3% for the period,
      and Archer-Daniels-Midland, a consumer staples company and a momentum
      model pick that posted serious losses for the period (down 21%).

QUESTIONS & ANSWERS

Q:    What changes did you make to the Fund's portfolio during the period?

A:    As a result of stock selection during the period, the portfolio's sector
      allocations changed somewhat. Overall portfolio turnover was 31% for the
      six months. We made no significant changes to the portfolio over this
      six-month period.

Q:    How do you intend to manage the Fund in the coming months?

A:    We continue to hold a positive view of the U.S. equity market. We think
      conditions may be especially favorable for large-cap stocks, which carry
      lower valuations on average than stocks of smaller companies. In
      addition, large-caps tend to appeal to investors seeking lower risk
      investments during what may be the last stage of the current economic
      recovery and a period when economic growth is expected to slow in what
      we would characterize as a "soft landing."

      INVESTMENT TERM

      SOFT LANDING: A term used to describe a rate of economic growth high
      enough to avoid recession but slow enough to avoid high inflation.

      For our part, we intend to continue seeking optimal returns for the Fund
      through the style diversification offered by our three quantitative
      investment models. We are equally convinced of the merit of our
      multifaceted, disciplined approach to controlling risk in the portfolio.
      We believe this combination of style diversification and rigorous risk
      control will allow us to maintain the high quality of the Fund's
      portfolio in whatever market conditions lie ahead.

10 RIVERSOURCE DISCIPLINED EQUITY FUND - 2007 SEMIANNUAL REPORT


FUND EXPENSES EXAMPLE

(UNAUDITED)

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments; and (2) ongoing
costs, which may include management fees; distribution and service (12b-1)
fees; and other Fund fees and expenses. This example is intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.
In addition to the ongoing expenses which the Fund bears directly, the Fund's
shareholders indirectly bear the expenses of the funds in which it invests
(also referred to as "acquired funds"), including affiliated and
non-affiliated pooled investment vehicles (including mutual funds and exchange
traded funds). The Fund's indirect expense from investing in the acquired
funds is based on the Fund's pro rata portion of the cumulative expenses
charged by the acquired funds using the acquired funds expense ratio as of the
most recent shareholder report.

The example is based on an investment of $1,000 invested at the beginning of
the period and held for the six months ended Jan. 31, 2007.

ACTUAL EXPENSES

The first line of the table provides information about actual account values
and actual expenses. You may use the information in this line, together with
the amount you invested, to estimate the expenses that you paid over the
period. 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
in the first line under the heading titled "Expenses paid during the period"
to estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table provides information about hypothetical account
values and hypothetical expenses based on the Fund's actual expense ratio and
an assumed rate of return of 5% per year before expenses, which is not the
Fund's actual return. 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 the 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). Therefore, the second line of 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.

(a)   Expenses are equal to the Fund's annualized expense ratio as indicated
      above, multiplied by the average account value over the period,
      multiplied by 184/365 (to reflect the one-half year period).

(b)   Based on the actual return for the six months ended Jan. 31, 2007:
      +14.15% for Class A, +13.72% for Class B, +13.68% for Class C, +14.37%
      for Class I and +14.22% for Class R4.

(c)   The actual values and expenses paid are not presented because Class R2,
      Class R3, Class R5 and Class W do not have a full six months of history.
      The inception date of Class R2, Class R3 and Class R5 is Dec. 11, 2006.
      The inception date of Class W is Dec. 1, 2006.

(d)   In September 2006, the Board approved renaming Class Y as Class R4,
      terminating the shareholder servicing agreement, revising the fee
      structure under the transfer agent agreement from an account-based fee
      to an asset-based fee, and adopting a plan administration services
      agreement. In addition, the investment manager and its affiliates have
      contractually agreed to waive certain fees and to absorb certain
      expenses until July 31, 2007, unless sooner terminated at the discretion
      of the Fund's Board, such that net expenses, (excluding fees and
      expenses of acquired funds) before giving effect to any performance
      incentive adjustment, will not exceed 0.84% for Class R4. Any amounts
      waived will not be reimbursed by the Fund. These changes were effective
      Dec. 11, 2006. If these changes had been in place for the six-month
      period ended Jan. 31, 2007, actual expenses paid for Class R4 would have
      been $4.54 and the hypothetical expenses paid for Class R4 would have
      been $4.28.

24 RIVERSOURCE DISCIPLINED EQUITY FUND - 2007 SEMIANNUAL REPORT


NOTES TO FINANCIAL STATEMENTS

(Unaudited as of Jan. 31, 2007)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Fund is a series of RiverSource Large Cap Series, Inc. and is registered
under the Investment Company Act of 1940 (as amended) as a diversified, open
end management investment company. RiverSource Large Cap Series, Inc. has 10
billion authorized shares of capital stock that can be allocated among the
separate series as designated by the Board. The Fund invests primarily in
equity securities of companies listed on U.S. exchanges with market
capitalizations greater than $5 billion at the time of purchase.

The Fund offers Class A, Class B, Class C and Class R4 shares.

o     Class A shares are sold with a front-end sales charge.

o     Class B shares may be subject to a contingent deferred sales charge
      (CDSC) and automatically convert to Class A shares during the ninth year
      of ownership.

o     Class C shares may be subject to a CDSC.

o     Class R4 shares have no sales charge and are offered only to qualifying
      institutional investors.

In September 2006, the Board approved renaming Class Y as Class R4,
terminating the shareholder servicing agreement, revising the fee structure
under the transfer agent agreement from account-based to asset-based, and
adopting a plan administration services agreement. These changes were
effective Dec. 11, 2006.

The Fund offers an additional class of shares, Class I, exclusively to certain
institutional investors. Class I shares have no sales charge and are made
available through a separate prospectus supplement provided to investors
eligible to purchase the shares. At Jan. 31, 2007, Ameriprise Financial, Inc.
(Ameriprise Financial) and the affiliated funds-of-funds owned 100% of Class I
shares.

Effective Dec.11, 2006, the Fund offers additional classes of shares, Class
R2, Class R3 and Class R5, offered to certain institutional investors. These
shares are sold without a front-end sales charge or CDSC. At Jan. 31, 2007,
Ameriprise Financial owned 100% of Class R2, Class R3 and Class R5 shares.

Effective Dec. 1, 2006, the Fund offers an additional class of shares, Class
W, offered through qualifying discretionary accounts. Class W shares are sold
without a front-end sales charge or CDSC.

At Jan. 31, 2007, Ameriprise Financial and the affiliated funds-of-funds owned
approximately 20% of the total outstanding Fund shares.


- ------------------------------------------------------------------------------

RIVERSOURCE DISCIPLINED EQUITY FUND - 2007 SEMIANNUAL REPORT 25


All classes of shares have identical voting, dividend and liquidation rights.
Class specific expenses (e.g., distribution and service fees, transfer agency
fees, plan administration fees) differ among classes. Income, expenses (other
than class specific expenses) and realized and unrealized gains or losses on
investments are allocated to each class of shares based upon its relative net
assets.

The Fund's significant accounting policies are summarized below:

USE OF ESTIMATES

Preparing financial statements that conform to U.S. generally accepted
accounting principles requires management to make estimates (e.g., on assets,
liabilities and contingent assets and liabilities) that could differ from
actual results.

VALUATION OF SECURITIES

All securities are valued at the close of each business day. Securities traded
on national securities exchanges or included in national market systems are
valued at the last quoted sales price. Debt securities are generally traded in
the over-the-counter market and are valued at a price that reflects fair value
as quoted by dealers in these securities or by an independent pricing service.
Pursuant to procedures adopted by the Board of Directors of the funds,
Ameriprise Financial utilizes Fair Value Pricing (FVP). FVP determinations are
made in good faith in accordance with these procedures. If a development or
event is so significant that there is a reasonably high degree of certainty
that the effect of the development or event has actually caused the closing
price to no longer reflect the actual value, the closing prices, as determined
at the close of the applicable foreign market, may be adjusted to reflect the
fair value of the affected foreign securities as of the close of the New York
Stock Exchange. Significant events include material movements in the U.S.
securities markets prior to the opening of foreign markets on the following
trading day. FVP results in an estimated price that reasonably reflects the
current market conditions in order to value the portfolio holdings such that
shareholder transactions receive a fair net asset value. Short term securities
maturing in more than 60 days from the valuation date are valued at the market
price or approximate market value based on current interest rates; those
maturing in 60 days or less are valued at amortized cost.

OPTION TRANSACTIONS

To produce incremental earnings, protect gains, and facilitate buying and
selling of securities for investments, the Fund may buy and write options
traded on any U.S. or foreign exchange or in the over-the-counter market where
completing the obligation depends upon the credit standing of the other party.
The Fund also may buy and sell put and call options and write covered call
options on portfolio securities as well as write cash-secured put options. The
risk in writing a call option is that the Fund gives up the opportunity for
profit if the market price of the security increases. The risk in writing a
put option is that the Fund may incur a loss if the market price of the
security decreases and the option is exercised. The risk in buying an option
is that the Fund pays a premium whether or not the option is exercised.


- ------------------------------------------------------------------------------

26 RIVERSOURCE DISCIPLINED EQUITY FUND - 2007 SEMIANNUAL REPORT


The Fund also has the additional risk of being unable to enter into a closing
transaction if a liquid secondary market does not exist.

Option contracts are valued daily at the closing prices on their primary
exchanges and unrealized appreciation or depreciation is recorded. The Fund
will realize a gain or loss when the option transaction expires or closes.
When an option is exercised, the proceeds on sales for a written call option,
the purchase cost for a written put option or the cost of a security for a
purchased put or call option is adjusted by the amount of premium received or
paid.

FUTURES TRANSACTIONS

To gain exposure to or protect itself from market changes, the Fund may buy
and sell financial futures contracts traded on any U.S. or foreign exchange.
The Fund also may buy and write put and call options on these futures
contracts. Risks of entering into futures contracts and related options
include the possibility of an illiquid market and that a change in the value
of the contract or option may not correlate with changes in the value of the
underlying securities.

Upon entering into a futures contract, the Fund is required to deposit either
cash or securities in an amount (initial margin) equal to a certain percentage
of the contract value. Subsequent payments (variation margin) are made or
received by the Fund each day. The variation margin payments are equal to the
daily changes in the contract value and are recorded as unrealized gains and
losses. The Fund recognizes a realized gain or loss when the contract is
closed or expires.

FOREIGN CURRENCY TRANSLATIONS AND FOREIGN CURRENCY CONTRACTS

Securities and other assets and liabilities denominated in foreign currencies
are translated daily into U.S. dollars. Foreign currency amounts related to
the purchase or sale of securities and income and expenses are translated at
the exchange rate on the transaction date. The effect of changes in foreign
exchange rates on realized and unrealized security gains or losses is
reflected as a component of such gains or losses. In the statement of
operations, net realized gains or losses from foreign currency transactions,
if any, may arise from sales of foreign currency, closed forward contracts,
exchange gains or losses realized between the trade date and settlement date
on securities transactions, and other translation gains or losses on
dividends, interest income and foreign withholding taxes.

The Fund may enter into forward foreign currency exchange contracts for
operational purposes and to protect against adverse exchange rate fluctuation.
The net U.S. dollar value of foreign currency underlying all contractual
commitments held by the Fund and the resulting unrealized appreciation or
depreciation are determined using foreign currency exchange rates from an
independent pricing service. The Fund is subject to the credit risk that the
other party will not complete its contract obligations.


- ------------------------------------------------------------------------------

RIVERSOURCE DISCIPLINED EQUITY FUND - 2007 SEMIANNUAL REPORT 27


GUARANTEES AND INDEMNIFICATIONS

Under the Fund's organizational documents, its officers and directors are
indemnified against certain liabilities arising out of the performance of
their duties to the Fund. In addition, certain of the Fund's contracts with
its service providers contain general indemnification clauses. The Fund's
maximum exposure under these arrangements is unknown since the amount of any
future claims that may be made against the Fund cannot be determined and the
Fund has no historical basis for predicting the likelihood of any such claims.

FEDERAL TAXES

The Fund's policy is to comply with Subchapter M of the Internal Revenue Code
that applies to regulated investment companies and to distribute substantially
all of its taxable income to shareholders. No provision for income or excise
taxes is thus required.

Net investment income (loss) and net realized gains (losses) may differ for
financial statement and tax purposes primarily because of deferred losses on
certain futures contracts, the recognition of certain foreign currency gains
(losses) as ordinary income (loss) for tax purposes, and losses deferred due
to "wash sale" transactions. The 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. Also, due to the
timing of dividend distributions, the fiscal year in which amounts are
distributed may differ from the year that the income or realized gains
(losses) were recorded by the Fund.

RECENT ACCOUNTING PRONOUNCEMENTS

On Sept. 20, 2006, the Financial Accounting Standards Board ("FASB") released
Statement of Financial Accounting Standards No. 157 "Fair Value Measurements"
("SFAS 157"). SFAS 157 establishes an authoritative definition of fair value,
sets out a framework for measuring fair value, and requires additional
disclosures about fair-value measurements. The application of SFAS 157 is
required for fiscal years beginning after Nov. 15, 2007 and interim periods
within those fiscal years. The impact of SFAS 157 on the Fund's financial
statements is being evaluated.

In June 2006, the Financial Accounting Standards Board (FASB) issued FASB
Interpretation 48 (FIN 48), "Accounting for Uncertainty in Income Taxes." FIN
48 clarifies the accounting for uncertainty in income taxes recognized in
accordance with FASB Statement 109, "Accounting for Income Taxes." FIN 48
prescribes a two-step process to recognize and measure a tax position taken or
expected to be taken in a tax return. The first step is to determine whether a
tax position has met the more-likely-than-not recognition threshold and the
second step is to measure a tax position that meets the threshold to determine
the amount of benefit to recognize. FIN 48 also provides guidance on
derecognition, classification, interest and penalties, accounting in interim
periods, disclosure and transition. FIN 48 is effective for fiscal years
beginning after Dec. 15, 2006. Tax positions of the Fund


- ------------------------------------------------------------------------------

28 RIVERSOURCE DISCIPLINED EQUITY FUND - 2007 SEMIANNUAL REPORT


are being evaluated to determine the impact, if any, to the Fund. The adoption
of FIN 48 is not anticipated to have a material impact on the Fund.

DIVIDENDS TO SHAREHOLDERS

An annual dividend from net investment income, declared and paid at the end of
the calendar year, when available, is reinvested in additional shares of the
Fund at net asset value or payable in cash. Capital gains, when available, are
distributed along with the income dividend. On March 7, 2006, an additional
dividend was paid before the merger to ensure that current shareholders of
RiverSource Disciplined Equity Fund would not experience a dilution in their
share of the Fund's income or capital gains.

OTHER

Security transactions are accounted for on the date securities are purchased
or sold. Dividend income is recognized on the ex dividend date and interest
income, including amortization of premium, market discount and original issue
discount using the effective interest method, is accrued daily.

2. EXPENSES AND SALES CHARGES

Under an Investment Management Services Agreement, RiverSource Investments,
LLC (the Investment Manager) determines which securities will be purchased,
held or sold. The management fee is a percentage of the Fund's average daily
net assets that declines from 0.60% to 0.375% annually as the Fund's assets
increase. The fee may be adjusted upward or downward by a performance
incentive adjustment based on a comparison of the performance of Class A
shares of the Fund to the Lipper Large-Cap Core Funds Index. In certain
circumstances, the Board may approve a change in the index. The maximum
adjustment is 0.12% per year. If the performance difference is less than
0.50%, the adjustment will be zero. The adjustment increased the fee by
$282,205 for the six months ended Jan. 31, 2007.

Under an Administrative Services Agreement, the Fund pays Ameriprise Financial
a fee for administration and accounting services at a percentage of the Fund's
average daily net assets that declines from 0.06% to 0.03% annually as the
Fund's assets increase.

Other expenses in the amount of $21,894 are for, among other things, certain
expenses of the Fund or the Board including: Fund boardroom and office
expense, employee compensation, employee health and retirement benefits, and
certain other expenses. Payment of these Fund and Board expenses is
facilitated by a company providing limited administrative services to the Fund
and the Board.

Compensation of Board members includes, for the former Board Chair,
compensation as well as retirement benefits. Certain other aspects of the
former Board Chair's compensation, including health benefits and payment of
certain other expenses, are included under other expenses.


- ------------------------------------------------------------------------------

RIVERSOURCE DISCIPLINED EQUITY FUND - 2007 SEMIANNUAL REPORT 29


Under a Deferred Compensation Plan (the Plan), non-interested board members
may defer receipt of their compensation. Deferred amounts are treated as
though equivalent dollar amounts had been invested in shares of the Fund or
other RiverSource funds. The Fund's liability for these amounts is adjusted
for market value changes and remains in the Fund until distributed in
accordance with the Plan.

Professional fees include fees paid by the Fund for legal services and
independent auditor services.

Under a Transfer Agency Agreement, RiverSource Service Corporation (the
Transfer Agent) maintains shareholder accounts and records. The Fund pays the
Transfer Agent an annual fee per shareholder account for this service as
follows:

o     Class A $19.50

o     Class B $20.50

o     Class C $20.00

Effective Dec. 11, 2006, as part of the Board's approval to rename Class Y as
Class R4, the fee structure under the Transfer Agency Agreement was revised
from an account-based fee for Class Y to an asset-based fee for Class R4. The
Fund will pay the Transfer Agent an annual asset-based fee at a rate of 0.05%
of the Fund's average daily net assets attributable to Class R4 shares. Prior
to Dec. 11, 2006, the Fund paid the Transfer Agent an annual account-based fee
of $17.50 per shareholder account.

In addition, with the introduction of Class R2, Class R3, Class R5 and Class W
shares, the Fund will pay the Transfer Agent an annual asset-based fee at a
rate of 0.05% of the Fund's average daily net assets attributable to Class R2,
Class R3 and Class R5 shares and an annual asset-based fee at a rate of 0.20%
of the Fund's average daily net assets attributable to Class W shares.

Prior to Dec. 11, 2006, Class I paid a transfer agency fee at an annual rate
per shareholder account of $1. This amount is included in the transfer agency
fee on the statement of operations. Effective Dec. 11, 2006, this fee was
eliminated.

The Transfer Agent charges an annual closed account fee of $5 per inactive
account, charged on a pro rata basis for 12 months from the date the account
becomes inactive. These fees are included in the transfer agency fees on the
statement of operations.

The Fund has agreements with Ameriprise Financial Services, Inc. and
RiverSource Distributors, Inc. (collectively, the Distributor) for
distribution and shareholder services. Under a Plan and Agreement of
Distribution pursuant to Rule 12b-1, the Fund pays a fee at an annual rate of
up to 0.25% of the Fund's average daily net assets attributable to Class A,
Class R3 and Class W shares, a fee at annual rate of up to 0.50% of the Fund's
average daily net assets attributable to Class R2 shares and a fee at an
annual rate of up to 1.00% of the Fund's average daily net assets attributable
to Class B and Class C shares.


- ------------------------------------------------------------------------------

30 RIVERSOURCE DISCIPLINED EQUITY FUND - 2007 SEMIANNUAL REPORT


Beginning Dec. 11, 2006, a new Plan Administration Services Agreement was
adopted for the restructured Class R4 and the introduction of Class R2 and
Class R3. The fee is calculated at a rate of 0.25% of the Fund's average daily
net assets attributable to Class R2, Class R3 and Class R4 shares.

Prior to Dec. 11, 2006, under a Shareholder Service Agreement, the Fund paid
the Distributor a fee for service provided to shareholders by the Distributor
and other servicing agents with respect to those shares. The fee was
calculated at a rate of 0.10% of the Fund's average daily net assets
attributable to Class Y shares. Effective Dec. 11, 2006, this agreement was
terminated.

Sales charges received by the Distributor for distributing Fund shares were
$304,595 for Class A, $24,021 for Class B and $279 for Class C for the six
months ended Jan. 31, 2007.

In addition to the fees and expenses which the Fund bears directly, the Fund
indirectly bears a pro rata share of the fees and expenses of the funds in
which it invests (also referred to as "acquired funds"), including affiliated
and non-affiliated pooled investment vehicles (including mutual funds and
exchange traded funds). Because the acquired funds have varied expense and fee
levels and the Fund may own different proportions of acquired funds at
different times, the amount of fees and expenses incurred indirectly by the
Fund will vary.

For the six months ended Jan. 31, 2007, the Investment Manager and its
affiliates waived certain fees and expenses to 1.03% for Class A, 1.80% for
Class B, 1.80% for Class C, 0.67% for Class I, 1.48% for Class R2, 1.23% for

32 RIVERSOURCE DISCIPLINED EQUITY FUND - 2007 SEMIANNUAL REPORT


5. LENDING OF PORTFOLIO SECURITIES

In order to generate additional income, the Fund may lend securities
representing up to one-third of the value of its total assets (which includes
collateral for securities on loan) to broker-dealers, banks, or other
institutional borrowers of securities. The Fund receives collateral in the
form of cash and U.S. government securities, equal to at least 100% of the
value of securities loaned, which is marked to the market value of the loaned
securities daily until the securities are returned, e.g., if the value of the
securities on loan increases, additional cash collateral is provided by the
borrower. The Investment Manager serves as securities lending agent for the
Fund under the investment management services agreement pursuant to which the
Fund has agreed to reimburse the Investment Manager for expenses incurred by
it in connection with the lending program, and pursuant to guidelines adopted
by and under the oversight of the Board. At Jan. 31, 2007, securities valued
at $23,731,566 were on loan to brokers. For collateral, the Fund received
$24,313,800 in cash. Cash collateral received is invested in an affiliated
money market fund and short-term securities, including U.S. government
securities or other high-grade debt obligations, which are included in the
"Investments in securities." Income from securities lending amounted to
$43,467 for the six months ended Jan. 31, 2007. The risks to the Fund of
securities lending are that the borrower may not provide additional collateral
when required or return the securities when due.

6. STOCK INDEX FUTURES CONTRACTS

At Jan. 31, 2007, investments in securities included securities valued at
$2,560,000 that were pledged as collateral to cover initial margin deposits on
10 open purchase contracts. The notional market value of the open purchase
contracts at Jan. 31, 2007 was $3,607,500 with a net unrealized loss of
$28,085. See "Summary of significant accounting policies" and "Notes to
investments in securities."

7. AFFILIATED MONEY MARKET FUND

The Fund may invest its daily cash balance in RiverSource Short-Term Cash
Fund, a money market fund established for the exclusive use of the RiverSource
funds and other institutional clients of RiverSource Investments.

RIVERSOURCE DISCIPLINED EQUITY FUND - 2007 SEMIANNUAL REPORT 33


8. BANK BORROWINGS

The Fund has a revolving credit agreement with a syndicate of banks headed by
JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the
temporary funding of shareholder redemptions or for other temporary or
emergency purposes. The agreement went into effect Sept. 19, 2006. The Fund
must maintain asset coverage for borrowings of at least 300%. The agreement,
which enables the Fund to participate with other RiverSource funds, permits
borrowings up to $500 million, collectively. Interest is charged to each Fund
based on its borrowings at a rate equal to either the higher of the Federal
Funds Effective Rate plus 0.40% or the JPMCB Prime Commercial Lending Rate.
Borrowings are payable within 60 days after such loan is executed. The Fund
also pays a commitment fee equal to its pro rata share of the amount of the
credit facility at a rate of 0.06% per annum. Prior to this agreement, the
Fund paid a commitment fee equal to its pro rata share of the amount of the
credit facility at a rate of 0.07% per annum. The Fund had no borrowings under
the facility outstanding during the six months ended Jan. 31, 2007.

9. FUND MERGER

At the close of business on March 10, 2006, RiverSource Disciplined Equity

10. INFORMATION REGARDING PENDING AND SETTLED LEGAL PROCEEDINGS

In June 2004, an action captioned John E. Gallus et al. v. American Express
Financial Corp. and American Express Financial Advisors Inc., was filed in the
United States District Court for the District of Arizona. The plaintiffs
allege that they are investors in several American Express Company mutual
funds and they purport to bring the action derivatively on behalf of those
funds under the Investment Company Act of 1940. The plaintiffs allege that
fees allegedly paid to the defendants by the funds for investment advisory and
administrative services are excessive. The plaintiffs seek remedies including
restitution and rescission of investment advisory and distribution agreements.
The plaintiffs voluntarily agreed to transfer this case to the United States
District Court for the District of Minnesota. In response to our motion to
dismiss the complaint, the Court dismissed one of plaintiffs' four claims and
granted plaintiffs limited discovery. Discovery is currently set to end in
March 2007.

In December 2005, without admitting or denying the allegations, American
Express Financial Corporation (AEFC, which is now known as Ameriprise
Financial, Inc. (Ameriprise Financial)), the parent company of RiverSource
Investments, LLC (RiverSource Investments), entered into settlement agreements
with the Securities and Exchange Commission (SEC) and Minnesota Department of
Commerce (MDOC) related to market timing activities. In connection with these
matters, the SEC and MDOC issued orders (the Orders) alleging that AEFC
violated certain provisions of the federal and Minnesota securities laws by
failing to adequately disclose market timing activities by allowing certain
identified market timers to continue to market time contrary to disclosures in
mutual fund and variable annuity product prospectuses. The Orders also alleged
that AEFC failed to implement procedures to detect and prevent market timing
in 401(k) plans for employees of AEFC and related companies and failed to
adequately disclose that there were no such procedures. Pursuant to the MDOC
Order, the MDOC also alleged that AEFC allowed inappropriate market timing to
occur by failing to have written policies and procedures and failing to
properly supervise its employees.

As a result of the Orders, AEFC was censured and ordered to cease and desist
from committing or causing any violations of certain provisions of the
Investment Advisers Act of 1940, the Investment Company Act of 1940, and
various Minnesota laws. Pursuant to the terms of the Orders, AEFC agreed to
pay disgorgement of $10 million and civil money penalties of $7 million. AEFC
also agreed to make presentations at least annually to its board of directors
and the relevant mutual funds' board that include an overview of policies and
procedures to prevent market timing, material changes to these policies and
procedures and whether disclosures related to market timing are consistent
with the SEC order and federal securities laws. AEFC also agreed to retain an
independent distribution consultant to assist in developing a plan for
distribution of all disgorgement and civil penalties ordered by the SEC in
accordance with various undertakings detailed at


- ------------------------------------------------------------------------------

RIVERSOURCE DISCIPLINED EQUITY FUND - 2007 SEMIANNUAL REPORT 35


http://www.sec.gov/litigation/admin/ia-2451.pdf. In addition, AEFC agreed to
complete and submit to the MDOC a compliance review of its procedures
regarding market timing within one year of the MDOC Order, including a summary
of actions taken to ensure compliance with applicable laws and regulations and
certification by a senior officer regarding compliance and supervisory
procedures.

Ameriprise Financial and its affiliates have cooperated with the SEC and the
MDOC in these legal proceedings, and have made regular reports to the
RiverSource Funds' Boards of Directors/Trustees.

Ameriprise Financial and certain of its affiliates have historically been
involved in a number of legal, arbitration and regulatory proceedings,
including routine litigation, class actions, and governmental actions,
concerning matters arising in connection with the conduct of their business
activities. Ameriprise Financial believes that the Funds are not currently the
subject of, and that neither Ameriprise Financial nor any of its affiliates
are the subject of, any pending legal, arbitration or regulatory proceedings
that are likely to have a material adverse effect on the Funds or the ability
of Ameriprise Financial or its affiliates to perform under their contracts
with the Funds. Ameriprise Financial is required to make 10-Q, 10-K and, as
necessary, 8-K filings with the Securities and Exchange Commission on legal
and regulatory matters that relate to Ameriprise Financial and its affiliates.
Copies of these filings may be obtained by accessing the SEC website at
www.sec.gov.

There can be no assurance that these matters, or the adverse publicity
associated with them, will not result in increased fund redemptions, reduced
sale of fund shares or other adverse consequences to the Funds. Further,
although we believe proceedings are not likely to have a material adverse
effect on the Funds or the ability of Ameriprise Financial or its affiliates
to perform under their contracts with the Funds, these proceedings are subject
to uncertainties and, as such, we are unable to estimate the possible loss or
range of loss that may result. An adverse outcome in one or more of these
proceedings could result in adverse judgments, settlements, fines, penalties
or other relief that could have a material adverse effect on the consolidated
financial condition or results of operations of Ameriprise Financial.

PERFORMANCE SUMMARY

                            PERFORMANCE COMPARISON
                 For the six-month period ended Jan. 31, 2007

[THE FOLLOWING TABLE WAS REPRESENTED AS A BAR CHART IN THE PRINTED MATERIAL.]


                                                             
RiverSource Growth Fund Class A (excluding sales charge)        +14.75%

Lipper Large-Cap Growth Funds Index(2)                          +13.57%

(1)   The Russell 1000(R) Growth Index, an unmanaged index, measures the
      performance of those stocks in the Russell 1000 Index with higher
      price-to-book ratios and higher forecasted growth values. The index
      reflects reinvestment of all distributions and changes in market prices,
      but excludes brokerage commissions or other fees.

(2)   The Lipper Large-Cap Growth Funds Index includes the 30 largest
      large-cap growth funds tracked by Lipper Inc. The index's returns
      include net reinvested dividends. The Fund's performance is currently
      measured against this index for purposes of determining the performance
      incentive adjustment.



The performance information shown represents past performance and is not a
guarantee of future results. The investment return and principal value of your
investment will fluctuate so that your shares, when redeemed, may be worth
more or less than their original cost. Current performance may be lower or
higher than the performance information shown. You may obtain performance
information current to the most recent month-end by contacting your financial
institution or visiting riversource.com/funds.

The 5.75% sales charge applicable to Class A shares of the Fund is not
reflected in the bar chart. If reflected, returns would be lower than those
shown. The performance of other classes may vary from that shown because of
differences in expenses.

The indices do not reflect the effects of sales charges, expenses (excluding
Lipper) and taxes.

It is not possible to invest directly in an index.

RIVERSOURCE GROWTH FUND - 2007 SEMIANNUAL REPORT  7


QUESTIONS & ANSWERS WITH PORTFOLIO MANAGEMENT

Below, Portfolio Manager Nick Thakore discusses the Fund's positioning and
results for the semiannual period ended Jan. 31, 2007.

Q:    How did RiverSource Growth Fund perform for the six months ended Jan.
      31, 2007?

A:    RiverSource Growth Fund's Class A shares rose 14.75%, excluding sales
      charge, for the six months ended Jan. 31, 2007. The Fund underperformed
      its benchmark, the Russell 1000(R) Growth Index (Russell Index), which
      advanced 15.12%, and outperformed its peer group as represented by the
      Lipper Large-Cap Growth Funds Index, which advanced 13.57% for the same
      period.

Q:    What factors influenced performance during the period?

A:    The stock market advanced sharply during the six months as economic
      growth continued and the Federal Reserve Board held interest rates
      steady after 17 consecutive increases in the federal funds rate.
      Notably, growth stocks outperformed value stocks in the large-cap
      universe and the Fund capitalized on the opportunities presented by a
      growth-led market.

      Stock selection was the main contributor to performance relative to the
      Russell Index. The information technology, energy and consumer staples
      sectors contributed positively to performance while positioning in the
      financials and materials sectors detracted from performance.

      Within the information technology sector, stock selection was
      beneficial, while an underweight position relative to the Russell Index
      was a slight disadvantage. Among the Fund's information technology
      holdings, an emphasis on larger-cap stocks proved effective during the
      period. The Fund benefited from positive stock selection in
      semiconductors, Internet-related companies, telecommunication equipment
      firms, networking providers and cell phone

      AMONG THE FUND'S INFORMATION TECHNOLOGY HOLDINGS, AN EMPHASIS ON
      LARGER-CAP STOCKS PROVED EFFECTIVE DURING THE PERIOD.

QUESTIONS & ANSWERS

      handset makers. The single largest contributor was semiconductor firm
      Freescale, which was bought out in a private equity transaction during
      the period and performed well. The Fund's holdings of Internet-related
      stocks also performed well, specifically search engine Google and
      Internet auction company eBay. A secular shift toward increased Internet
      advertising continued to support Internet-related firms. We had added
      significantly to eBay during the period when we felt the stock price
      reflected the company's missteps. Subsequently, the Fund benefited when
      eBay's stock advanced during the period.

      Stock selection in the energy sector positively impacted performance as
      did the Fund's smaller-than-Russell Index position in the energy sector.
      Specifically, the Fund's position in integrated oil company Exxon Mobil
      was a key contributor, as the company showed strong production growth
      and demonstrated solid free cash flow trends.

      In the consumer staples sector, stock selection contributed positively
      to the Fund's performance. An emphasis on larger-cap stocks within the
      sector, as well as positioning in the household products, grocery and
      tobacco groups was beneficial. Spectrum Brands, a maker of batteries,
      fertilizer and other household products, was the leading contributor
      within consumer staples, followed by the Safeway grocery store chain.
      Spectrum Brands advanced as the stock's valuation became more attractive
      following a period of underperformance that was driven by the pressure
      of rising raw material prices and unfulfilled expectations for
      merger-related synergies. Safeway, a turnaround story in the grocery
      segment, advanced on same store sales trends that were better than
      anticipated.

      In the financials sector, stock selection was the primary detractor,
      although a smaller-than-Russell Index weighting was also
      disadvantageous. In particular, the portfolio had less exposure to
      brokerage firms and investment management companies than the Russell
      Index and these stocks advanced sharply as a number of firms displayed
      resilient earnings growth that continued to surpass the market.

RIVERSOURCE GROWTH FUND - 2007 SEMIANNUAL REPORT  9


QUESTIONS & ANSWERS

Q:    What changes did you make to the Fund's portfolio during the six-month
      period?

A:    We continued to see a promising combination of attractive valuations and
      high growth rates for telecommunication stocks. During the semiannual
      period, we adjusted the Fund's telecommunication positioning, reducing
      the Fund's Sprint Nextel position given concerns about near term
      fundamentals.

      We increased the portfolio's information technology position as we
      identified selected stocks that had previously underperformed and, in
      our view, had reasonable valuations relative to their growth rates.

Q:    How are you positioning the Fund going forward?

A:    We think corporate earnings growth is likely to decelerate, given that
      profit margins are at record levels and leading indicators point to
      potential for margin erosion. In addition, consumer spending could
      decline as higher borrowing costs and a weaker housing market may affect
      consumer confidence.

      Given our current outlook, we have emphasized stable growth companies
      over cyclical growth companies, preferring to own companies with strong
      growth potential less dependent on the economy. We continue to find
      opportunities among large-cap companies that still appear inexpensive
      relative to mid- and small-cap stocks based on the historical
      relationships between these groups and improving relative fundamentals.
      In general, we believe the Fund holds stocks that, as a group, are
      likely to grow earnings faster than the market and are at attractive
      valuation levels. We see opportunities among fast growth companies that
      have underperformed, which has made valuations more attractive
      particularly in the biotechnology and technology industries.

10  RIVERSOURCE GROWTH FUND - 2007 SEMIANNUAL REPORT


FUND EXPENSES EXAMPLE

(UNAUDITED)

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments; and (2) ongoing
costs, which may include management fees; distribution and service (12b-1)
fees; and other Fund fees and expenses. This example is intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.
In addition to the ongoing expenses which the Fund bears directly, the Fund's
shareholders indirectly bear the expenses of the funds in which it invests
(also referred to as "acquired funds"), including affiliated and
non-affiliated pooled investment vehicles (including mutual funds and exchange
traded funds). The Fund's indirect expense from investing in the acquired
funds is based on the Fund's pro rata portion of the cumulative expenses
charged by the acquired funds using the acquired funds expense ratio as of the
most recent shareholder report.

The example is based on an investment of $1,000 invested at the beginning of
the period and held for the six months ended Jan. 31, 2007.

ACTUAL EXPENSES

The first line of the table provides information about actual account values
and actual expenses. You may use the information in this line, together with
the amount you invested, to estimate the expenses that you paid over the
period. 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
in the first line under the heading titled "Expenses paid during the period"
to estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table provides information about hypothetical account
values and hypothetical expenses based on the Fund's actual expense ratio and
an assumed rate of return of 5% per year before expenses, which is not the
Fund's actual return. 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 the 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). Therefore, the second line of 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.

(a)   Expenses are equal to the Fund's annualized expense ratio as indicated
      above, multiplied by the average account value over the period,
      multiplied by 184/365 (to reflect the one-half year period).

(b)   Based on the actual return for the six months ended Jan. 31, 2007:
      +14.75% for Class A, +14.31% for Class B, +14.31% for Class C, +15.01%
      for Class I and +14.84% for Class R4.

(c)   The actual values and expenses paid are not presented because Class R2,
      Class R3, Class R5 and Class W do not have a full six months of history.
      The inception date of Class R2, Class R3 and Class R5 is Dec. 11, 2006.
      The inception date of Class W is Dec. 1, 2006.

(d)   In September 2006, the Board approved renaming Class Y as Class R4,
      terminating the shareholder servicing agreement, revising the fee
      structure under the transfer agent agreement from an account-based fee
      to an asset-based fee, and adopting a plan administration services
      agreement. In addition, the investment manager and its affiliates have
      contractually agreed to waive certain fees and to absorb certain
      expenses until July 31, 2007, unless sooner terminated at the discretion
      of the Fund's Board, such that net expenses (excluding fees and expenses
      of acquired funds), before giving effect to any performance incentive
      adjustment, will not exceed 0.97% for Class R4. Any amounts waived will
      not be reimbursed by the Fund. These changes were effective Dec. 11,
      2006. If these changes had been in place for the six-month period ended
      Jan. 31, 2007, actual expenses paid for Class R4 would have been $5.74
      and the hypothetical expenses paid for Class R4 would have been $5.40.

RIVERSOURCE GROWTH FUND - 2007 SEMIANNUAL REPORT  23


NOTES TO FINANCIAL STATEMENTS

(Unaudited as to Jan. 31, 2007)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Fund is a series of RiverSource Large Cap Series, Inc. and is registered
under the Investment Company Act of 1940 (as amended) as a diversified,
open-end management investment company. RiverSource Large Cap Series, Inc. has
10 billion authorized shares of capital stock that can be allocated among the
separate series as designated by the Board. The Fund invests primarily in
common stocks of U.S. and foreign companies that appear to offer growth
opportunities.

The Fund offers Class A, Class B, Class C and Class R4 shares.

o     Class A shares are sold with a front-end sales charge.

o     Class B shares may be subject to a contingent deferred sales charge
      (CDSC) and automatically convert to Class A shares during the ninth year
      of ownership.

o     Class C shares may be subject to a CDSC.

o     Class R4 shares have no sales charge and are offered only to qualifying
      institutional investors.

In September 2006, the Board approved renaming Class Y as Class R4,
terminating the shareholder servicing agreement, revising the fee structure
under the transfer agent agreement from account-based to asset-based, and
adopting a plan administration services agreement. These changes were
effective Dec. 11, 2006.

The Fund offers an additional class of shares, Class I, exclusively to certain
institutional investors. Class I shares have no sales charge and are made
available through a separate prospectus supplement provided to investors
eligible to purchase the shares. At Jan. 31, 2007, Ameriprise Financial, Inc.
(Ameriprise Financial) and the affiliated funds-of-funds owned 100% of Class I
shares.

Effective Dec. 11, 2006, the Fund offers additional classes of shares, Class
R2, Class R3 and Class R5, offered to certain institutional investors. These
shares are sold without a front-end sales charge or CDSC. At Jan. 31, 2007,
Ameriprise Financial owned 100% of Class R2, Class R3 and Class R5 shares.

Effective Dec. 1, 2006, the Fund offers an additional class of shares, Class
W, offered through qualifying discretionary accounts. Class W shares are sold
without a front-end sales charge or CDSC. At Jan. 31, 2007, Ameriprise
Financial owned 100% of Class W shares.

At Jan. 31, 2007, Ameriprise Financial and the affiliated funds-of-funds owned
approximately 10% of the total outstanding Fund Shares.


- ------------------------------------------------------------------------------

24  RIVERSOURCE GROWTH FUND - 2007 SEMIANNUAL REPORT


All classes of shares have identical voting, dividend and liquidation rights.
Class specific expenses (e.g., distribution and service fees, transfer agency
fees, plan administration fees) differ among classes. Income, expenses (other
than class specific expenses) and realized and unrealized gains or losses on
investments are allocated to each class of shares based upon its relative net
assets.

The Fund's significant accounting policies are summarized below:

USE OF ESTIMATES

Preparing financial statements that conform to U.S. generally accepted
accounting principles requires management to make estimates (e.g., on assets,
liabilities and contingent assets and liabilities) that could differ from
actual results.

VALUATION OF SECURITIES

All securities are valued at the close of each business day. Securities traded
on national securities exchanges or included in national market systems are
valued at the last quoted sales price. Debt securities are generally traded in
the over-the-counter market and are valued at a price that reflects fair value
as quoted by dealers in these securities or by an independent pricing service.
Pursuant to procedures adopted by the Board of Directors of the funds,
Ameriprise Financial utilizes Fair Value Pricing (FVP). FVP determinations are
made in good faith in accordance with these procedures. If a development or
event is so significant that there is a reasonably high degree of certainty
that the effect of the development or event has actually caused the closing
price to no longer reflect the actual value, the closing prices, as determined
at the close of the applicable foreign market, may be adjusted to reflect the
fair value of the affected foreign securities as of the close of the New York
Stock Exchange. Significant events include material movements in the U.S.
securities markets prior to the opening of foreign markets on the following
trading day. FVP results in an estimated price that reasonably reflects the
current market conditions in order to value the portfolio holdings such that
shareholder transactions receive a fair net asset value. Short-term securities
maturing in more than 60 days from the valuation date are valued at the market
price or approximate market value based on current interest rates; those
maturing in 60 days or less are valued at amortized cost.

RIVERSOURCE GROWTH FUND - 2007 SEMIANNUAL REPORT  25


ILLIQUID SECURITIES

At Jan. 31, 2007, investments in securities included issues that are illiquid
which the Fund currently limits to 10% of net assets, at market value, at the
time of purchase. The aggregate value of such securities as of Jan. 31, 2007
was $36,246,322 representing 1.00% of net assets. These securities are valued
at fair value according to methods selected in good faith by the Board.
According to board guidelines, certain unregistered securities are determined
to be liquid and are not included within the 10% limitation specified above.
Assets are liquid if they can be sold or disposed of in the ordinary course of
business within seven days at approximately the value which the asset is
valued by the Fund.

OPTION TRANSACTIONS

To produce incremental earnings, protect gains and facilitate buying and
selling of securities for investments, the Fund may buy and write options
traded on any U.S. or foreign exchange or in the over-the-counter market where
completing the obligation depends upon the credit standing of the other party.
The Fund also may buy and sell put and call options and write covered call
options on portfolio securities as well as write cash-secured put options. The
risk in writing a call option is that the Fund gives up the opportunity for
profit if the market price of the security increases. The risk in writing a
put option is that the Fund may incur a loss if the market price of the
security decreases and the option is exercised. The risk in buying an option
is that the Fund pays a premium whether or not the option is exercised. The
Fund also has the additional risk of being unable to enter into a closing
transaction if a liquid secondary market does not exist.

Option contracts are valued daily at the closing prices on their primary
exchanges and unrealized appreciation or depreciation is recorded. The Fund
will realize a gain or loss when the option transaction expires or closes.
When an option is exercised, the proceeds on sales for a written call option,
the purchase cost for a written put option or the cost of a security for a
purchased put or call option is adjusted by the amount of premium received or
paid.

FUTURES TRANSACTIONS

To gain exposure to or protect itself from market changes, the Fund may buy
and sell financial futures contracts traded on any U.S. or foreign exchange.
The Fund also may buy and write put and call options on these futures
contracts. Risks of entering into futures contracts and related options
include the possibility of an illiquid market and that a change in the value
of the contract or option may not correlate with changes in the value of the
underlying securities.


- ------------------------------------------------------------------------------

26  RIVERSOURCE GROWTH FUND - 2007 SEMIANNUAL REPORT


Upon entering into a futures contract, the Fund is required to deposit either
cash or securities in an amount (initial margin) equal to a certain percentage
of the contract value. Subsequent payments (variation margin) are made or
received by the Fund each day. The variation margin payments are equal to the
daily changes in the contract value and are recorded as unrealized gains and
losses. The Fund recognizes a realized gain or loss when the contract is
closed or expires.

FOREIGN CURRENCY TRANSLATIONS AND FOREIGN CURRENCY CONTRACTS

Securities and other assets and liabilities denominated in foreign currencies
are translated daily into U.S. dollars. Foreign currency amounts related to
the purchase or sale of securities and income and expenses are translated at
the exchange rate on the transaction date. The effect of changes in foreign
exchange rates on realized and unrealized security gains or losses is
reflected as a component of such gains or losses. In the statement of
operations, net realized gains or losses from foreign currency transactions,
if any, may arise from sales of foreign currency, closed forward contracts,
exchange gains or losses realized between the trade date and settlement date
on securities transactions, and other translation gains or losses on
dividends, interest income and foreign withholding taxes. At Jan. 31, 2007,
foreign currency holdings were entirely comprised of European monetary units.

The Fund may enter into forward foreign currency exchange contracts for
operational purposes and to protect against adverse exchange rate fluctuation.
The net U.S. dollar value of foreign currency underlying all contractual
commitments held by the Fund and the resulting unrealized appreciation or
depreciation are determined using foreign currency exchange rates from an
independent pricing service. The Fund is subject to the credit risk that the
other party will not complete its contract obligations.

GUARANTEES AND INDEMNIFICATIONS

Under the Fund's organizational documents, its officers and directors are
indemnified against certain liabilities arising out of the performance of
their duties to the Fund. In addition, certain of the Fund's contracts with
its service providers contain general indemnification clauses. The Fund's
maximum exposure under these arrangements is unknown since the amount of any
future claims that may be made against the Fund cannot be determined and the
Fund has no historical basis for predicting the likelihood of any such claims.

FEDERAL TAXES

The Fund's policy is to comply with Subchapter M of the Internal Revenue Code
that applies to regulated investment companies and to distribute substantially
all of its taxable income to the shareholders. No provision for income or
excise taxes is thus required.


- ------------------------------------------------------------------------------

RIVERSOURCE GROWTH FUND - 2007 SEMIANNUAL REPORT  27


Net investment income (loss) and net realized gains (losses) may differ for
financial statement and tax purposes primarily because of deferred losses on
certain futures contracts and losses deferred due to "wash sale" transactions.
The 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. Also, due to the timing of dividend
distributions, the fiscal year in which amounts are distributed may differ
from the year that the income or realized gains (losses) were recorded by the
Fund.

RECENT ACCOUNTING PRONOUNCEMENTS

On Sept. 20, 2006, the Financial Accounting Standards Board ("FASB") released
Statement of Financial Accounting Standards No. 157 "Fair Value Measurements"
("SFAS 157"). SFAS 157 establishes an authoritative definition of fair value,
sets out a framework for measuring fair value, and requires additional
disclosures about fair-value measurements. The application of SFAS 157 is
required for fiscal years beginning after Nov. 15, 2007 and interim periods
within those fiscal years. The impact of SFAS 157 on the Fund's financial
statements is being evaluated.

In June 2006, the Financial Accounting Standards Board (FASB) issued FASB
Interpretation 48 (FIN 48), "Accounting for Uncertainty in Income Taxes." FIN
48 clarifies the accounting for uncertainty in income taxes recognized in
accordance with FASB Statement 109, "Accounting for Income Taxes." FIN 48
prescribes a two-step process to recognize and measure a tax position taken or
expected to be taken in a tax return. The first step is to determine whether a
tax position has met the more-likely-than-not recognition threshold and the
second step is to measure a tax position that meets the threshold to determine
the amount of benefit to recognize. FIN 48 also provides guidance on
derecognition, classification, interest and penalties, accounting in interim
periods, disclosure and transition. FIN 48 is effective for fiscal years
beginning after Dec. 15, 2006. Tax positions of the Fund are being evaluated
to determine the impact, if any, to the Fund. The adoption of FIN 48 is not
anticipated to have a material impact on the Fund.

DIVIDENDS TO SHAREHOLDERS

An annual dividend from net investment income, declared and paid at the end of
the calendar year, when available, is reinvested in additional shares of the
Fund at net asset value or payable in cash. Capital gains, when available, are
distributed along with the income dividend.


- ------------------------------------------------------------------------------

28  RIVERSOURCE GROWTH FUND - 2007 SEMIANNUAL REPORT


OTHER

Security transactions are accounted for on the date securities are purchased
or sold. Interest income, including amortization of premium, market discount
and original issue discount using the effective interest method, is accrued
daily.

2. EXPENSES AND SALES CHARGES

Under an Investment Management Services Agreement, RiverSource Investments,
LLC (the Investment Manager) determines which securities will be purchased,
held or sold. The management fee is a percentage of the Fund's average daily
net assets that declines from 0.60% to 0.375% annually as the Fund's assets
increase. The fee may be adjusted upward or downward by a performance
incentive adjustment based on a comparison of the performance of Class A
shares of the Fund to the Lipper Large-Cap Growth Funds Index. In certain
circumstances, the Board may approve a change in the index. The maximum
adjustment is 0.12% per year.

If the performance difference is less than 0.50%, the adjustment will be zero.
The adjustment increased the fee by $1,753,422 for the six months ended Jan.
31, 2007.

Under an Administrative Services Agreement, the Fund pays Ameriprise Financial
a fee for administration and accounting services at a percentage of the Fund's
average daily net assets that declines from 0.06% to 0.03% annually as the
Fund's assets increase.

Other expenses in the amount of $33,499 are for, among other things, certain
expenses of the Fund or the Board including: Fund boardroom and office
expense, employee compensation, employee health and retirement benefits, and
certain other expenses. Payment of these Fund and Board expenses is
facilitated by a company providing limited administrative services to the Fund
and the Board.

Compensation of Board members includes, for the former Board Chair,
compensation as well as retirement benefits. Certain other aspects of the
former Board Chair's compensation, including health benefits and payment of
certain other expenses, are included under other expenses.

Under a Deferred Compensation Plan (the Plan), non-interested board members
may defer receipt of their compensation. Deferred amounts are treated as
though equivalent dollar amounts had been invested in shares of the Fund or
other RiverSource funds. The Fund's liability for these amounts is adjusted
for market value changes and remains in the Fund until distributed in
accordance with the Plan.


- ------------------------------------------------------------------------------

RIVERSOURCE GROWTH FUND - 2007 SEMIANNUAL REPORT  29


Professional fees include fees paid by the Fund for legal services and
independent auditor services.

Under a Transfer Agency Agreement, RiverSource Service Corporation (the
Transfer Agent) maintains shareholder accounts and records. The Fund pays the
Transfer Agent an annual fee per shareholder account for this service as
follows:

o     Class A $19.50

o     Class B $20.50

o     Class C $20.00

Effective Dec. 11, 2006, as part of the Board's approval to rename Class Y as
Class R4, the fee structure under the Transfer Agency Agreement was revised
from an account-based fee for Class Y to an asset-based fee for Class R4. The
Fund will pay the Transfer Agent an annual asset-based fee of 0.05% of the
Fund's average daily net asset attributable to Class R4 shares. Prior to Dec.
11, 2006, the Fund paid the Transfer Agent an annual account-based fee of
$17.50 per shareholder account.

In addition, with the introduction of Class R2, Class R3, Class R5 and Class W
shares, the Fund will pay the Transfer Agent an annual asset-based fee at a
rate of 0.05% of the Fund's average daily net assets attributable to Class R2,
Class R3 and Class R5 shares and an annual asset-based fee at a rate of 0.20%
of the Fund's average daily net assets attributable to Class W shares.

Prior to Dec. 11, 2006, Class I paid a transfer agency fee at an annual rate
per shareholder account of $1. This amount is included in the transfer agency
fee on the statement of operations. Effective Dec. 11, 2006, this fee was
eliminated.

The Transfer Agent charges an annual closed account fee of $5 per inactive
account, charged on a pro rata basis for 12 months from the date the account
becomes inactive. These fees are included in the transfer agency fees on the
statement of operations.

The Fund has agreements with Ameriprise Financial Services, Inc. and
RiverSource Distributors, Inc. (collectively, the Distributor) for
distribution and shareholder services. Under a Plan and Agreement of
Distribution pursuant to Rule 12b-1, the Fund pays a fee at an annual rate of
up to 0.25% of the Fund's average daily net assets attributable to Class A,
Class R3 and Class W shares, a fee at an annual rate of up to 0.50% of the
Fund's average daily net assets attributable to Class R2 shares and a fee at
an annual rate of up to 1.00% of the Fund's average daily net assets
attributable to Class B and Class C shares.


- ------------------------------------------------------------------------------

30  RIVERSOURCE GROWTH FUND - 2007 SEMIANNUAL REPORT


Beginning Dec. 11, 2006, a new Plan Administration Services Agreement was
adopted for the restructured Class R4 and the introduction of Class R2 and
Class R3. The fee is calculated at a rate of 0.25% of the Fund's average daily
net assets attributable to Class R2, Class R3 and Class R4 shares.

Prior to Dec. 11, 2006, under a Shareholder Service Agreement, the Fund paid
the Distributor a fee for service provided to shareholders by the Distributor
and other servicing agents with respect to those shares. The fee was
calculated at a rate of 0.10% of the Fund's average daily net assets
attributable to Class Y shares. Effective Dec. 11, 2006, this agreement was
terminated.

Sales charges received by the Distributor for distributing Fund shares were
$1,298,997 for Class A, $229,341 for Class B and $1,641 for Class C for the
six months ended Jan. 31, 2007.

In addition to the fees and expenses which the Fund bears directly, the Fund
indirectly bears a pro rata share of the fees and expenses of the funds in
which it invests (also referred to as "acquired funds"), including affiliated
and non-affiliated pooled investment vehicles (including mutual funds and
exchange traded funds). Because the acquired funds have varied expense and fee
levels and the Fund may own different proportions of acquired funds at
different times, the amount of fees and expenses incurred indirectly by the
Fund will vary.

Effective Dec. 11, 2006, with the renaming of Class Y as Class R4, the
Investment Manager and its affiliates have agreed to waive certain fees and
expenses until July 31, 2007, unless sooner terminated at the discretion of
the Board, such that net expenses (excluding fees and expenses of acquired
funds), before giving effect to any performance incentive adjustment, will not
exceed 0.97% for Class R4.

During the six months ended Jan. 31, 2007, the Fund's custodian and transfer
agency fees were reduced by $135,166 as a result of earnings and bank fee
credits from overnight cash balances. The Fund also pays custodian fees to
Ameriprise Trust Company, an affiliate of Ameriprise Financial.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $1,550,820,368 and $1,876,771,037, respectively, for
the six months ended Jan. 31, 2007. Realized gains and losses are determined
on an identified cost basis.

5. FORWARD FOREIGN CURRENCY CONTRACTS

At Jan. 31, 2007, the Fund has a forward foreign currency exchange contract
that obligates it to deliver currency at a specified future date. The
unrealized depreciation on this contract is included in the accompanying
financial statements. See "Summary of significant accounting policies." The
terms of the open contract are as follows:



EXCHANGE DATE                                CURRENCY TO      CURRENCY TO      UNREALIZED          UNREALIZED

6. LENDING OF PORTFOLIO SECURITIES

In order to generate additional income, the Fund may lend securities
representing up to one-third of the value of its total assets (which includes
collateral for securities on loan) to broker-dealers, banks, or other
institutional borrowers of securities. The Fund receives collateral in the
form of cash and U.S. government securities, equal to at least 100% of the
value of securities loaned, which is marked to the market value of the loaned
securities daily until the securities are returned, e.g., if the value of the
securities on loan increases, additional cash collateral is provided by the
borrower. The Investment Manager serves as securities lending agent for the
Fund under the investment management services agreement pursuant to which the
Fund has agreed to reimburse the Investment Manager for expenses incurred by
it in connection with the lending program, and pursuant to guidelines adopted
by and under the oversight of the Board. At Jan. 31, 2007, securities valued
at $19,759,321 were on loan to brokers. For collateral, the Fund received
$20,514,175 in cash. Cash collateral received is invested in an affiliated
money market fund and short-term securities, including U.S. government
securities or other high-grade debt obligations, which are included in the
"Investments in securities." Income from securities lending amounted to
$59,140 for the six months ended Jan. 31, 2007. The risks to the Fund of
securities lending are that the borrower may not provide additional collateral
when required or return the securities when due.

7. OPTIONS CONTRACTS WRITTEN

Contracts and premiums associated with options contracts written are as

RIVERSOURCE GROWTH FUND - 2007 SEMIANNUAL REPORT  33


8. AFFILIATED MONEY MARKET FUND

The Fund may invest its daily cash balance in RiverSource Short-Term Cash
Fund, a money market fund established for the exclusive use of the RiverSource
funds and other institutional clients of RiverSource Investments.

9. BANK BORROWINGS

The Fund has a revolving credit agreement with a syndicate of banks headed by
JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the
temporary funding of shareholder redemptions or for other temporary or
emergency purposes. The agreement went into effect Sept. 19, 2006. The Fund
must maintain asset coverage for borrowings of at least 300%. The agreement,
which enables the Fund to participate with other RiverSource funds, permits
borrowings up to $500 million, collectively. Interest is charged to each Fund
based on its borrowings at a rate equal to either the higher of the Federal
Funds Effective Rate plus 0.40% or the JPMCB Prime Commercial Lending Rate.
Borrowings are payable within 60 days after such loan is executed. The Fund
also pays a commitment fee equal to its pro rata share of the amount of the
credit facility at a rate of 0.06% per annum. Prior to this agreement, the
Fund paid a commitment fee equal to its pro rata share of the amount of the
credit facility at a rate of 0.07% per annum. The Fund had no borrowings under
the facility outstanding during the six months ended Jan. 31, 2007.

10. CAPITAL LOSS CARRY-OVER

For federal income tax purposes, the Fund had a capital loss carry-over of
$535,377,023 at July 31, 2006, that if not offset by capital gains will expire
as follows:



                            2010                   2011
                                            
                        $166,602,696           $368,774,327


It is unlikely the Board will authorize a distribution of any net realized
capital gains until the available capital loss carry-over has been offset or
expires.

11. INFORMATION REGARDING PENDING AND SETTLED LEGAL PROCEEDINGS

In June 2004, an action captioned John E. Gallus et al. v. American Express
Financial Corp. and American Express Financial Advisors Inc., was filed in the
United States District Court for the District of Arizona. The plaintiffs
allege that they are investors in several American Express Company mutual
funds and they purport to bring the action derivatively on behalf of those
funds under the Investment Company Act of 1940. The plaintiffs allege that
fees allegedly paid to the defendants by the funds for investment advisory and
administrative services are excessive. The plaintiffs seek remedies including
restitution and rescission of investment advisory and distribution agreements.
The plaintiffs voluntarily agreed to transfer this case to the United States
District Court for the District of Minnesota. In response to our motion to
dismiss the complaint, the Court dismissed one of plaintiffs' four claims and
granted plaintiffs limited discovery. Discovery is currently set to end in
March 2007.

In December 2005, without admitting or denying the allegations, American
Express Financial Corporation (AEFC, which is now known as Ameriprise
Financial, Inc. (Ameriprise Financial)), the parent company of RiverSource
Investments, LLC (RiverSource Investments), entered into settlement agreements
with the Securities and Exchange Commission (SEC) and Minnesota Department of
Commerce (MDOC) related to market timing activities. In connection with these
matters, the SEC and MDOC issued orders (the Orders) alleging that AEFC
violated certain provisions of the federal and Minnesota securities laws by
failing to adequately disclose market timing activities by allowing certain
identified market timers to continue to market time contrary to disclosures in
mutual fund and variable annuity product prospectuses. The Orders also alleged
that AEFC failed to implement procedures to detect and prevent market timing
in 401(k) plans for employees of AEFC and related companies and failed to
adequately disclose that there were no such procedures. Pursuant to the MDOC
Order, the MDOC also alleged that AEFC allowed inappropriate market timing to
occur by failing to have written policies and procedures and failing to
properly supervise its employees.

As a result of the Orders, AEFC was censured and ordered to cease and desist
from committing or causing any violations of certain provisions of the
Investment Advisers Act of 1940, the Investment Company Act of 1940, and
various Minnesota laws. Pursuant to the terms of the Orders, AEFC agreed to
pay disgorgement of $10 million and civil money penalties of $7 million. AEFC
also agreed to make presentations at least annually to its board of directors
and the relevant mutual


- ------------------------------------------------------------------------------

RIVERSOURCE GROWTH FUND - 2007 SEMIANNUAL REPORT  35


funds' board that include an overview of policies and procedures to prevent
market timing, material changes to these policies and procedures and whether
disclosures related to market timing are consistent with the SEC order and
federal securities laws. AEFC also agreed to retain an independent
distribution consultant to assist in developing a plan for distribution of all
disgorgement and civil penalties ordered by the SEC in accordance with various
undertakings detailed at http://www.sec.gov/litigation/admin/ia-2451.pdf. In
addition, AEFC agreed to complete and submit to the MDOC a compliance review
of its procedures regarding market timing within one year of the MDOC Order,
including a summary of actions taken to ensure compliance with applicable laws
and regulations and certification by a senior officer regarding compliance and
supervisory procedures.

Ameriprise Financial and its affiliates have cooperated with the SEC and the
MDOC in these legal proceedings, and have made regular reports to the
RiverSource Funds' Boards of Directors/Trustees.

Ameriprise Financial and certain of its affiliates have historically been
involved in a number of legal, arbitration and regulatory proceedings,
including routine litigation, class actions, and governmental actions,
concerning matters arising in connection with the conduct of their business
activities. Ameriprise Financial believes that the Funds are not currently the
subject of, and that neither Ameriprise Financial nor any of its affiliates
are the subject of, any pending legal, arbitration or regulatory proceedings
that are likely to have a material adverse effect on the Funds or the ability
of Ameriprise Financial or its affiliates to perform under their contracts
with the Funds. Ameriprise Financial is required to make 10-Q, 10-K and, as
necessary, 8-K filings with the Securities and Exchange Commission on legal
and regulatory matters that relate to Ameriprise Financial and its affiliates.
Copies of these filings may be obtained by accessing the SEC website at
www.sec.gov.

There can be no assurance that these matters, or the adverse publicity
associated with them, will not result in increased fund redemptions, reduced
sale of fund shares or other adverse consequences to the Funds. Further,
although we believe proceedings are not likely to have a material adverse
effect on the Funds or the ability of Ameriprise Financial or its affiliates
to perform under their contracts with the Funds, these proceedings are subject
to uncertainties and, as such, we are unable to estimate the possible loss or
range of loss that may result. An adverse outcome in one or more of these
proceedings could result in adverse judgments, settlements, fines, penalties
or other relief that could have a material adverse effect on the consolidated
financial condition or results of operations of Ameriprise Financial.

      Russell 3000 Index. The index reflects reinvestment of all distributions
      and changes in market prices.

(2)   The S&P 500 Index, an unmanaged index of common stocks, is frequently
      used as a general measure of market performance. The index reflects
      reinvestment of all distributions and changes in market prices.

(3)   The Lipper Large-Cap Core Funds Index includes the 30 largest large-cap
      core funds tracked by Lipper Inc. The index's returns include net
      reinvested dividends. The Fund's performance is currently measured
      against this index for purposes of determining the performance incentive
      adjustment. See "Fund Management and Compensation" for more information.

RIVERSOURCE LARGE CAP EQUITY FUND - 2007 SEMIANNUAL REPORT 7


QUESTIONS & ANSWERS WITH PORTFOLIO MANAGEMENT

Below, Bob Ewing and Nick Thakore, RiverSource Large Cap Equity Fund's
portfolio managers, discuss the Fund's results and positioning for the
semiannual period ended Jan. 31, 2007.

Q:    How did RiverSource Large Cap Equity Fund perform for the six-month
      period ended Jan. 31, 2007?

A:    RiverSource Large Cap Equity Fund's Class A shares advanced 14.64%,
      excluding sales charge, for the six months ended Jan. 31, 2007. The Fund
      outperformed its benchmarks, the Russell 1000(R) Index (Russell Index)
      and the Standard & Poor's 500 Index (S&P 500 Index), which increased
      14.28% and 13.75%, respectively. The Fund's peer group, the Lipper
      Large-Cap Core Funds Index, gained 13.17% during the same time frame.

Q:    What factors most significantly affected performance for the period?

A:    U.S. stocks advanced sharply during the past six months, supported by
      continued economic growth, corporate earnings and the Federal Reserve
      Board's monetary policy, which held short-term interest rates steady.
      Large-cap growth stocks outperformed large-cap value stocks and because
      we had positioned the portfolio with more of a growth tilt than was
      typical, the Fund was rewarded during the semiannual period.

      The Fund's strong performance during the past six months resulted from
      positive stock selection. The information technology, consumer staples
      and energy sectors were the primary contributors to performance during
      the period, while positioning in the materials and financials sectors
      detracted from performance.

      Within the information technology sector, positive stock selection drove
      the Fund's results. An emphasis on cell phone handset manufacturers,
      such as Nokia, and networking companies, such as Cisco Systems,
      contributed positively to results. Semiconductor firm Freescale was the
      single largest individual contributor as the company was bought out by
      private equity investors. Nokia and other handset makers have continued
      to benefit from the strong growth trends in the telecommunication
      services sector, while Cisco Systems has demonstrated that it is in the
      midst of a strong product cycle.

      THE FUND'S STRONG PERFORMANCE DURING THE PAST SIX MONTHS RESULTED FROM
      POSITIVE STOCK SELECTION.


- ------------------------------------------------------------------------------

8 RIVERSOURCE LARGE CAP EQUITY FUND - 2007 SEMIANNUAL REPORT


QUESTIONS & ANSWERS

      Stock selection in the consumer staples sector benefited from
      larger-than-Russell Index positions within the household products group,
      where stocks such as Spectrum Brands and Procter & Gamble performed
      well. Household products is traditionally a defensive industry and
      earnings in the group remained stable while overall market earnings
      showed signs of slowing. Within consumer staples, we also emphasized
      retail grocers, another defensive segment. Safeway, a turnaround story
      in this group, outperformed as same store sales were better than
      expected.

      The Fund had a smaller energy position than the Russell Index due to our
      concern that higher prices would dampen global demand. Reduced emphasis
      on energy was beneficial during this period. Within the energy sector,
      stock selection was also favorable as we had relatively small exposure
      to refining companies and energy services firms. These are typically the
      riskier stocks within the sector and our smaller allocations were
      advantageous. A larger-than-Russell Index position in integrated oil
      companies helped performance.

      Within the materials sector, the Fund had de-emphasized base metals, an
      area that outperformed during the period. During the period, metals
      stocks got a boost from expected merger and acquisition activity,
      despite the overall sharp decline in many commodity prices.

      In the financials sector, stock selection was the primary detractor to
      performance. The portfolio had less exposure to brokerage firms and
      investment management companies than the Russell Index, which ended up
      negatively impacting the Fund's performance. Many of these stocks
      advanced sharply on earnings growth that continued to exceed
      expectations.

Q:    What changes did you make to the portfolio and how is it currently
      positioned?

A:    We sold selected stocks in the Fund's portfolio when valuations
      approached our target levels, taking some profits as a result. We added
      judiciously to large-cap companies in the information technology and
      health care sectors, focusing on stocks where we think valuations are
      reasonable relative to our expectations for their growth rates.


- ------------------------------------------------------------------------------

RIVERSOURCE LARGE CAP EQUITY FUND - 2007 SEMIANNUAL REPORT 9


QUESTIONS & ANSWERS

      In the telecommunication services sector, we continued to see a
      promising combination of powerful trends, high free cash flow yields and
      high growth rates for telecommunication stocks. We fine-tuned the Fund's
      telecommunication services positioning during the six-month period,
      reducing its Sprint Nextel position and adding to companies that are
      executing better growth.

Q:    How do you plan to manage the Fund in coming months?

A:    We currently see corporate profit margins at record levels, while at the
      same time, there are signs of slower global economic growth. In
      addition, continued high energy prices, increased borrowing costs and a
      weaker U.S. housing market could lead consumers to reduce their
      spending. All of these suggest that corporate profit growth is likely to
      decelerate.

      Given this scenario, we are maintaining an emphasis on stable growth
      companies, those whose earnings growths are less dependent on the
      economy. Also, among companies whose earnings are tied to the economy,
      we are looking for situations where the cyclical nature of those
      earnings has already been discounted in the stock price. We continue to
      emphasize larger-cap stocks that still appear inexpensive relative to
      mid- and small-cap stocks based on the historical relationships between
      these groups.

10 RIVERSOURCE LARGE CAP EQUITY FUND - 2007 SEMIANNUAL REPORT


FUND EXPENSES EXAMPLE

(UNAUDITED)

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments; and (2) ongoing
costs, which may include management fees; distribution and service (12b-1)
fees; and other Fund fees and expenses. This example is intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.
In addition to the ongoing expenses which the Fund bears directly, the Fund's
shareholders indirectly bear the expenses of the funds in which it invests
(also referred to as "acquired funds"), including affiliated and
non-affiliated pooled investment vehicles (including mutual funds and exchange
traded funds). The Fund's indirect expense from investing in the acquired
funds is based on the Fund's pro rata portion of the cumulative expenses
charged by the acquired funds using the acquired funds expense ratio as of the
most recent shareholder report.

The example is based on an investment of $1,000 invested at the beginning of
the period and held for the six months ended Jan. 31, 2007.

ACTUAL EXPENSES

The first line of the table provides information about actual account values
and actual expenses. You may use the information in this line, together with
the amount you invested, to estimate the expenses that you paid over the
period. 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
in the first line under the heading titled "Expenses paid during the period"
to estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table provides information about hypothetical account
values and hypothetical expenses based on the Fund's actual expense ratio and
an assumed rate of return of 5% per year before expenses, which is not the
Fund's actual return. 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 the 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). Therefore, the second line of 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.

(a)   Expenses are equal to the Fund's annualized expense ratio as indicated
      above, multiplied by the average account value over the period,
      multiplied by 184/365 (to reflect the one-half year period).

(b)   Based on the actual return for the six months ended Jan. 31, 2007:
      +14.64% for Class A, +14.13% for Class B, +14.02% for Class C, +14.61%
      for Class I and +14.48% for Class R4.

(c)   The actual values and expenses paid are not presented because Class R2,
      Class R3 and Class R5 do not have a full six months of history. The
      inception date of Class R2, Class R3 and Class R5 is Dec. 11, 2006.

(d)   In September 2006, the Board approved renaming Class Y as Class R4,
      terminating the shareholder servicing agreement, revising the fee
      structure under the transfer agent agreement from an account-based fee
      to an asset-based fee, and adopting a plan administration services
      agreement. In addition, the investment manager and its affiliates have
      contractually agreed to waive certain fees and to absorb certain
      expenses until July 31, 2007, unless sooner terminated at the discretion
      of the Fund's Board, such that net expenses (excluding fees and expenses
      of acquired funds), before giving effect to any performance incentive
      adjustment, will not exceed 0.90% for Class R4. Any amounts waived will
      not be reimbursed by the Fund. These changes were effective Dec. 11,
      2006. If these changes had been in place for the six-month period ended
      Jan. 31, 2007, the actual expenses paid for Class R4 would have been
      $4.87 and the hypothetical expenses paid for Class R4 would have been
      $4.58.

28 RIVERSOURCE LARGE CAP EQUITY FUND - 2007 SEMIANNUAL REPORT


NOTES TO FINANCIAL STATEMENTS

(Unaudited as to Jan. 31, 2007)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Fund is a series of RiverSource Large Cap Series, Inc. and is registered
under the Investment Company Act of 1940 (as amended) as a diversified,
open-end management investment company. RiverSource Large Cap Series, Inc. has
10 billion authorized shares of capital stock that can be allocated among the
separate series as designated by the Board. The Fund invests primarily in
equity securities of companies with a market capitalization greater than $5
billion at the time of purchase.

The Fund offers Class A, Class B, Class C and Class R4 shares.

o     Class A shares are sold with a front-end sales charge.

o     Class B shares may be subject to a contingent deferred sales charge
      (CDSC) and automatically convert to Class A shares during the ninth year
      of ownership.

o     Class C shares may be subject to a CDSC.

o     Class R4 shares have no sales charge and are offered only to qualifying
      institutional investors.

In September 2006, the Board approved renaming Class Y as Class R4,
terminating the shareholder servicing agreement, revising the fee structure
under the transfer agent agreement from account-based to asset-based, and
adopting a plan administration services agreement. These changes were
effective Dec. 11, 2006.

The Fund offers an additional class of shares, Class I, exclusively to certain
institutional investors. Class I shares have no sales charge and are made
available through a separate prospectus supplement provided to investors
eligible to purchase the shares. At Jan. 31, 2007, Ameriprise Financial, Inc.
(Ameriprise Financial) and the affiliated funds-of-funds owned 100% of Class I
shares.

Effective Dec. 11, 2006, the Fund offers additional classes of shares, Class
R2, Class R3 and Class R5, offered to certain institutional investors. These
shares are sold without a front-end sales charge or CDSC. At Jan. 31, 2007,
Ameriprise Financial owned 100% of Class R2, Class R3 and Class R5 shares.

At Jan. 31, 2007, Ameriprise Financial and the affiliated funds-of-funds owned
approximately 2% of the total outstanding Fund shares.

All classes of shares have identical voting, dividend and liquidation rights.
Class specific expenses (e.g., distribution and service fees, transfer agency
fees, plan administration fees) differ among classes. Income, expenses (other
than class specific expenses) and realized and unrealized gains or losses on
investments are allocated to each class of shares based upon its relative net
assets.


- ------------------------------------------------------------------------------

RIVERSOURCE LARGE CAP EQUITY FUND - 2007 SEMIANNUAL REPORT 29


The Fund's significant accounting policies are summarized below:

USE OF ESTIMATES

Preparing financial statements that conform to U.S. generally accepted
accounting principles requires management to make estimates (e.g., on assets,
liabilities and contingent assets and liabilities) that could differ from
actual results.

VALUATION OF SECURITIES

All securities are valued at the close of each business day. Securities traded
on national securities exchanges or included in national market systems are
valued at the last quoted sales price. Debt securities are generally traded in
the over-the-counter market and are valued at a price that reflects fair value
as quoted by dealers in these securities or by an independent pricing service.
Pursuant to procedures adopted by the Board of Directors of the funds,
Ameriprise Financial utilizes Fair Value Pricing (FVP). FVP determinations are
made in good faith in accordance with these procedures. If a development or
event is so significant that there is a reasonably high degree of certainty
that the effect of the development or event has actually caused the closing
price to no longer reflect the actual value, the closing prices, as determined
at the close of the applicable foreign market, may be adjusted to reflect the
fair value of the affected foreign securities as of the close of the New York
Stock Exchange. Significant events include material movements in the U.S.
securities markets prior to the opening of foreign markets on the following
trading day. FVP results in an estimated price that reasonably reflects the
current market conditions in order to value the portfolio holdings such that
shareholder transactions receive a fair net asset value. Short-term securities
maturing in more than 60 days from the valuation date are valued at the market
price or approximate market value based on current interest rates; those
maturing in 60 days or less are valued at amortized cost.

ILLIQUID SECURITIES

As of Jan. 31, 2007, investments in securities included issues that are
illiquid which the Fund currently limits to 10% of net assets, at market
value, at the time of purchase. The aggregate value of such securities at Jan.
31, 2007 was $27,955,414 representing 0.39% of net assets. These securities
are valued at fair value according to methods selected in good faith by the
Board. According to board guidelines, certain unregistered securities are
determined to be liquid and are not included within the 10% limitation
specified above. Assets are liquid if they can be sold or disposed of in the
ordinary course of business within seven days at approximately the value at
which the asset is valued by the Fund.

OPTION TRANSACTIONS

To produce incremental earnings, protect gains, and facilitate buying and
selling of securities for investments, the Fund may buy and write options
traded on any U.S. or foreign exchange or in the over-the-counter market where
completing the obligation depends upon the credit standing of the other party.
The Fund also may buy and sell put and call options and write covered call
options on portfolio


- ------------------------------------------------------------------------------

30 RIVERSOURCE LARGE CAP EQUITY FUND - 2007 SEMIANNUAL REPORT


securities as well as write cash-secured put options. The risk in writing a
call option is that the Fund gives up the opportunity for profit if the market
price of the security increases. The risk in writing a put option is that the
Fund may incur a loss if the market price of the security decreases and the
option is exercised. The risk in buying an option is that the Fund pays a
premium whether or not the option is exercised. The Fund also has the
additional risk of being unable to enter into a closing transaction if a
liquid secondary market does not exist.

Option contracts are valued daily at the closing prices on their primary
exchanges and unrealized appreciation or depreciation is recorded. The Fund
will realize a gain or loss when the option transaction expires or closes.
When an option is exercised, the proceeds on sales for a written call option,
the purchase cost for a written put option or the cost of a security for a
purchased put or call option is adjusted by the amount of premium received or
paid.

FUTURES TRANSACTIONS

To gain exposure to or protect itself from market changes, the Fund may buy
and sell financial futures contracts traded on any U.S. or foreign exchange.
The Fund also may buy and write put and call options on these futures
contracts. Risks of entering into futures contracts and related options
include the possibility of an illiquid market and that a change in the value
of the contract or option may not correlate with changes in the value of the
underlying securities.

Upon entering into a futures contract, the Fund is required to deposit either
cash or securities in an amount (initial margin) equal to a certain percentage
of the contract value. Subsequent payments (variation margin) are made or
received by the Fund each day. The variation margin payments are equal to the
daily changes in the contract value and are recorded as unrealized gains and
losses. The Fund recognizes a realized gain or loss when the contract is
closed or expires.

FOREIGN CURRENCY TRANSLATIONS AND FOREIGN CURRENCY CONTRACTS

Securities and other assets and liabilities denominated in foreign currencies
are translated daily into U.S. dollars. Foreign currency amounts related to
the purchase or sale of securities and income and expenses are translated at
the exchange rate on the transaction date. The effect of changes in foreign
exchange rates on realized and unrealized security gains or losses is
reflected as a component of such gains or losses. In the statement of
operations, net realized gains or losses from foreign currency transactions,
if any, may arise from sales of foreign currency, closed forward contracts,
exchange gains or losses realized between the trade date and settlement date
on securities transactions, and other translation gains or losses on
dividends, interest income and foreign withholding taxes. At Jan. 31, 2007,
foreign currency holdings consisted of multiple denominations, primarily
European monetary units.


- ------------------------------------------------------------------------------

RIVERSOURCE LARGE CAP EQUITY FUND - 2007 SEMIANNUAL REPORT 31


The Fund may enter into forward foreign currency exchange contracts for
operational purposes. The net U.S. dollar value of foreign currency underlying
all contractual commitments held by the Fund and the resulting unrealized
appreciation or depreciation are determined using foreign currency exchange
rates from an independent pricing service. The Fund is subject to the credit
risk that the other party will not complete its contract obligations.

TOTAL RETURN EQUITY SWAP TRANSACTIONS

The Fund may enter into swap agreements to earn the total return on a
specified security, basket of securities or security indexes during the
specified period, in return for periodic payments based on a fixed or variable
interest rate of the total return from other underlying assets. Total return
swap agreements may be used to obtain exposure to a security or market without
owning or taking physical custody of such security or market. Under the terms
of a total return equity swap agreement, payments made by the Fund or the
counterparty are based on the total return of a particular reference asset or
assets (such as an equity security, a combination of such securities, or an
index). That is, one party agrees to pay another party the return on a stock,
basket of stocks, or stock index in return for a specified interest rate.

The notional amounts of swap contracts are not recoded in the financial
statements. Swap contracts are valued daily, and the change in value is
recorded as unrealized appreciation (depreciation) until the termination of
the swap, at which time realized gain (loss) is recorded. Payments received or
made are recorded as realized gains (losses).

Swap agreements may be subject to liquidity risk, which exists when a
particular swap is difficult to purchase or sell. It may not be possible for
the Fund to initiate a transaction or liquidate a position at an advantageous
time or price, which may result in significant losses. Total return swaps are
subject to the risk associated with the investment in the underlying
securities and also the risk of the counterparty not fulfilling its
obligations under the agreement.

GUARANTEES AND INDEMNIFICATIONS

Under the Fund's organizational documents, its officers and directors are
indemnified against certain liabilities arising out of the performance of
their duties to the Fund. In addition, certain of the Fund's contracts with
its service providers contain general indemnification clauses. The Fund's
maximum exposure under these arrangements is unknown since the amount of any
future claims that may be made against the Fund cannot be determined and the
Fund has no historical basis for predicting the likelihood of any such claims.

FEDERAL TAXES

The Fund's policy is to comply with Subchapter M of the Internal Revenue Code
that applies to regulated investment companies and to distribute substantially
all of its taxable income to shareholders. No provision for income or excise
taxes is thus required.


- ------------------------------------------------------------------------------

32 RIVERSOURCE LARGE CAP EQUITY FUND - 2007 SEMIANNUAL REPORT


Net investment income (loss) and net realized gains (losses) may differ for
financial statement and tax purposes primarily because of deferred losses on
certain futures contracts, the recognition of certain foreign currency gains
(losses) as ordinary income (loss) for tax purposes and losses deferred due to
"wash sale" transactions. The 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. Also, due to the
timing of dividend distributions, the fiscal year in which amounts are
distributed may differ from the year that the income or realized gains
(losses) were recorded by the Fund.

RECENT ACCOUNTING PRONOUNCEMENTS

On Sept. 20, 2006, the Financial Accounting Standards Board ("FASB") released
Statement of Financial Accounting Standards No. 157 "Fair Value Measurements"
("SFAS 157"). SFAS 157 establishes an authoritative definition of fair value,
sets out a framework for measuring fair value, and requires additional
disclosures about fair-value measurements. The application of SFAS 157 is
required for fiscal years beginning after Nov. 15, 2007 and interim periods
within those fiscal years. The impact of SFAS 157 on the Fund's financial
statements is being evaluated.

In June 2006, the Financial Accounting Standards Board (FASB) issued FASB
Interpretation 48 (FIN 48), "Accounting for Uncertainty in Income Taxes." FIN
48 clarifies the accounting for uncertainty in income taxes recognized in
accordance with FASB Statement 109, "Accounting for Income Taxes." FIN 48
prescribes a two-step process to recognize and measure a tax position taken or
expected to be taken in a tax return. The first step is to determine whether a
tax position has met the more-likely-than-not recognition threshold and the
second step is to measure a tax position that meets the threshold to determine
the amount of benefit to recognize. FIN 48 also provides guidance on
derecognition, classification, interest and penalties, accounting in interim
periods, disclosure and transition. FIN 48 is effective for fiscal years
beginning after Dec. 15, 2006. Tax positions of the Fund are being evaluated
to determine the impact, if any, to the Fund. The adoption of FIN 48 is not
anticipated to have a material impact on the Fund.

DIVIDENDS TO SHAREHOLDERS

An annual dividend from net investment income, declared and paid at the end of
the calendar year, when available, is reinvested in additional shares of the
Fund at net asset value or payable in cash. Capital gains, when available, are
distributed along with the income dividend. On March 7, 2006, an additional
dividend was paid before the merger to ensure that current shareholders of
RiverSource Large Cap Equity Fund would not experience a dilution in their
share of the fund's income or capital gains.


- ------------------------------------------------------------------------------

RIVERSOURCE LARGE CAP EQUITY FUND - 2007 SEMIANNUAL REPORT 33


OTHER

Security transactions are accounted for on the date securities are purchased
or sold. Dividend income is recognized on the ex-dividend date and interest
income, including amortization of premium, market discount and original issue
discount using the effective interest method, is accrued daily.

2. EXPENSES AND SALES CHARGES

Under an Investment Management Services Agreement, RiverSource Investments,
LLC (the Investment Manager) determines which securities will be purchased,
held or sold. The management fee is a percentage of the Fund's average daily
net assets that declines from 0.60% to 0.375% annually as the Fund's assets
increase. The fee may be adjusted upward or downward by a performance
incentive adjustment based on a comparison of the performance of Class A
shares of the Fund to the Lipper Large-Cap Core Funds Index. In certain
circumstances, the Board may approve a change in the index. The maximum
adjustment is 0.12% per year. If the performance difference is less than
0.50%, the adjustment will be zero. The adjustment increased the fee by
$22,717 for the period ended Jan. 31, 2007.

Under an Administrative Services Agreement, the Fund pays Ameriprise Financial
a fee for administration and accounting services at a percentage of the Fund's
average daily net assets that declines from 0.06% to 0.03% annually as the
Fund's assets increase.

Other expenses in the amount of $67,840 are for, among other things, certain
expenses of the Fund or the Board including: Fund boardroom and office
expense, employee compensation, employee health and retirement benefits, and
certain other expenses. Payment of these Fund and Board expenses is
facilitated by a company providing limited administrative services to the Fund
and the Board.

Compensation of Board members includes, for the former Board Chair,
compensation as well as retirement benefits. Certain other aspects of the
former Board Chair's compensation, including health benefits and payment of
certain other expenses, are included under other expenses.

Under a Deferred Compensation Plan (the Plan), non-interested board members
may defer receipt of their compensation. Deferred amounts are treated as
though equivalent dollar amounts had been invested in shares of the Fund or
other RiverSource funds. The Fund's liability for these amounts is adjusted
for market value changes and remains in the Fund until distributed in
accordance with the Plan.

Professional fees include fees paid by the Fund for legal services and
independent auditor services.

34 RIVERSOURCE LARGE CAP EQUITY FUND - 2007 SEMIANNUAL REPORT


Under a Transfer Agency Agreement, RiverSource Service Corporation (the
Transfer Agent) maintains shareholder accounts and records. The Fund pays the
Transfer Agent an annual fee per shareholder account for this service as
follows:

o     Class A $19.50

o     Class B $20.50

o     Class C $20.00

Effective Dec. 11, 2006, as part of the Board's approval to rename Class Y to
R4, the fee structure under the Transfer Agency Agreement was revised from an
account-based fee for Class Y to an asset-based fee for Class R4. The Fund
will pay the Transfer Agent an annual asset-based fee at a rate of 0.05% of
the Fund's average daily net assets attributable to Class R4 shares. Prior to
Dec. 11, 2006, the Fund paid the Transfer Agent an annual account-based fee of
$17.50 per shareholder account.

In addition, with the introduction of Class R2, Class R3 and Class R5 shares,
the Fund will pay the Transfer Agent an annual asset-based fee at a rate of
0.05% of the Fund's average daily net assets attributable to Class R2, Class
R3 and Class R5 shares.

Prior to Dec. 11, 2006, Class I paid a transfer agency fee at an annual rate
per shareholder account of $1. This amount is included in the transfer agency
fee on the statement of operations. Effective Dec. 11, 2006, this fee was
eliminated.

The Transfer Agent charges an annual closed account fee of $5 per inactive
account, charged on a pro rata basis for 12 months from the date the account
becomes inactive. These fees are included in the transfer agency fees on the
statement of operations.

The Fund has agreements with Ameriprise Financial Services, Inc. and
RiverSource Distributors, Inc. (collectively, the Distributor) for
distribution and shareholder services. Under a Plan and Agreement of
Distribution pursuant to Rule 12b-1, the Fund pays a fee at an annual rate of
up to 0.25% of the Fund's average daily net assets attributable to Class A and
Class R3 shares, a fee at annual rate of up to 0.50% of the Fund's average
daily net assets attributable to Class R2 shares and a fee at an annual rate
of up to 1.00% of the Fund's average daily net assets attributable to Class B
and Class C shares.

Beginning Dec. 11, 2006, a new Plan Administration Services Agreement was
adopted for the restructured Class R4 and the introduction of Class R2, Class
R3 and Class R5. The fee is calculated at a rate of 0.25% of the Fund's
average daily net assets attributable to Class R2, Class R3, Class R4 and
Class R5 shares.


- ------------------------------------------------------------------------------

RIVERSOURCE LARGE CAP EQUITY FUND - 2007 SEMIANNUAL REPORT 35


Prior to Dec. 11, 2006, under a Shareholder Service Agreement, the Fund paid
the Distributor a fee for service provided to shareholders by the Distributor
and other servicing agents with respect to those shares. The fee was
calculated at a rate of 0.10% of the Fund's average daily net assets
attributable to Class Y shares. Effective Dec. 11, 2006, this agreement was
terminated.

Sales charges received by the Distributor for distributing Fund shares were
$3,865,781 for Class A, $1,329,901 for Class B and $4,452 for Class C for the
six months ended Jan. 31, 2007.

In addition to the fees and expenses which the Fund bears directly, the Fund
indirectly bears a pro rata share of the fees and expenses of the funds in
which it invests (also referred to as "acquired funds"), including affiliated
and non-affiliated pooled investment vehicles (including mutual funds and
exchange traded funds). Because the acquired funds have varied expense and fee
levels and the Fund may own different proportions of acquired funds at
different times, the amount of fees and expenses incurred indirectly by the
Fund will vary.

For the six months ended Jan. 31, 2007, the Investment Manager and its
affiliates waived certain fees and expenses to 0.87% for Class R4. The
transfer agency fees waived for Class R4 were $2,538. Effective Dec. 11, 2006,
with the renaming of Class Y as Class R4, the Investment Manager and its
affiliates have agreed to waive certain fees and expenses until July 31, 2007,
unless sooner terminated at the discretion of the Board, such that net
expenses (excluding fees and expenses of acquired funds), before giving effect
to any performance incentive adjustment, will not exceed 0.90% for Class R4.

During the six months ended Jan. 31, 2007, the Fund's custodian and transfer
agency fees were reduced by $477,104 as a result of earnings and bank fee
credits from overnight cash balances. The Fund also pays custodian fees to
Ameriprise Trust Company, an affiliate of Ameriprise Financial.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $2,372,926,475 and $4,093,144,136, respectively, for

6. STOCK INDEX FUTURES CONTRACTS

At Jan. 31, 2007, investments in securities included securities valued at
$6,469,360 that were pledged as collateral to cover initial margin deposits on
115 open purchase contracts. The notional market value of the open purchase
contracts at Jan. 31, 2007 was $41,486,250 with a net unrealized gain of
$275,415. See "Summary of significant accounting policies" and "Notes to
investments in securities."

7. LENDING OF PORTFOLIO SECURITIES

In order to generate additional income, the Fund may lend securities
representing up to one-third of the value of its total assets (which includes
collateral for securities on loan) to broker-dealers, banks, or other
institutional borrowers of securities. The Fund receives collateral in the
form of cash and U.S. government securities, equal to at least 100% of the
value of securities loaned, which is marked to the market value of the loaned
securities daily until the securities are returned, e.g., if the value of the
securities on loan increases, additional cash collateral is provided by the
borrower. The Investment Manager serves as securities lending agent for the
Fund under the investment management services agreement pursuant to which the
Fund has agreed to reimburse the Investment Manager for expenses incurred by
it in connection with the lending program, and pursuant to guidelines adopted
by and under the oversight of the Board. At Jan. 31, 2007, securities valued
at $44,899,184 were on loan to brokers. For collateral, the Fund received
$46,412,700 in cash. Cash collateral received is invested in an affiliated
money market fund and short-term securities, including U.S. government
securities or other high-grade debt obligations, which are included in the
"Investments in securities." Income from securities lending amounted to
$113,312 for the six months ended Jan. 31, 2007. The risks to the Fund of
securities lending are that the borrower may not provide additional collateral
when required or return the securities when due.

8. OPTIONS CONTRACTS WRITTEN

Contracts and premiums associated with options contracts written are as
follows:



                                                SIX MONTHS ENDED JAN. 31, 2007

10. AFFILIATED MONEY MARKET FUND

The Fund may invest its daily cash balance in RiverSource Short-Term Cash
Fund, a money market fund established for the exclusive use of the RiverSource
funds and other institutional clients of RiverSource Investments.

11. BANK BORROWINGS

The Fund has a revolving credit agreement with a syndicate of banks headed by
JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the
temporary funding of shareholder redemptions or for other temporary or
emergency purposes. The agreement went into effect Sept.19, 2006. The Fund
must maintain asset coverage for borrowings of at least 300%. The agreement,
which enables the Fund to participate with other RiverSource funds, permits
borrowings up to $500 million, collectively. Interest is charged to each Fund
based on its borrowings at a rate equal to either the higher of the Federal
Funds Effective Rate plus 0.40% or the JPMCB Prime Commercial Lending Rate.
Borrowings are payable within 60 days after such loan is executed. The Fund
also pays a commitment fee equal to its pro rata share of the amount of the
credit facility at a rate of 0.06% per annum. Prior to this agreement, the
Fund paid a commitment fee equal to its pro rata share of the amount of the
credit facility at a rate of 0.07% per annum. The Fund had no borrowings under
the facility outstanding during the six months ended Jan. 31, 2007.

- --------------------------------------------------------------------------------

40 RIVERSOURCE LARGE CAP EQUITY FUND - 2007 SEMIANNUAL REPORT


RiverSource Large Cap Equity Fund acquired $33,183,702 of capital loss
carry-overs in connection with the RiverSource New Dimensions Fund merger
(Note 12). In addition to the acquired capital loss carry-overs, the Fund also
acquired unrealized capital gains as a result of the mergers. The yearly
utilization of the acquired capital losses as well as the utilization of the
acquired unrealized losses is limited by the Internal Revenue Code. It is
unlikely the Board will authorize a distribution of any net realized capital
gains until the available capital loss carry-over has been offset or expires.

In June 2004, an action captioned John E. Gallus et al. v. American Express
Financial Corp. and American Express Financial Advisors Inc., was filed in the
United States District Court for the District of Arizona. The plaintiffs
allege that they are investors in several American Express Company mutual
funds and they purport to bring the action derivatively on behalf of those
funds under the Investment Company Act of 1940. The plaintiffs allege that
fees allegedly paid to the defendants by the funds for investment advisory and
administrative services are excessive. The plaintiffs seek remedies including
restitution and rescission of investment advisory and distribution agreements.
The plaintiffs voluntarily agreed to transfer this case to the United States
District Court for the District of Minnesota. In response to our motion to
dismiss the complaint, the Court dismissed one of plaintiffs' four claims and
granted plaintiffs limited discovery. Discovery is currently set to end in
March 2007.

In December 2005, without admitting or denying the allegations, American
Express Financial Corporation (AEFC, which is now known as Ameriprise
Financial, Inc. (Ameriprise Financial)), the parent company of RiverSource
Investments, LLC (RiverSource Investments), entered into settlement agreements
with the Securities and Exchange Commission (SEC) and Minnesota Department of
Commerce (MDOC) related to market timing activities. In connection with these
matters, the SEC and MDOC issued orders (the Orders) alleging that AEFC
violated certain provisions of the federal and Minnesota securities laws by
failing to adequately disclose market timing activities by allowing certain
identified market timers to continue to market time contrary to disclosures in
mutual fund and variable annuity product prospectuses. The Orders also alleged
that AEFC failed to implement procedures to detect and prevent market timing
in 401(k) plans for employees of AEFC and related companies and failed to
adequately disclose that there were no such procedures. Pursuant to the MDOC
Order, the MDOC also alleged that AEFC allowed inappropriate market timing to
occur by failing to have written policies and procedures and failing to
properly supervise its employees.

As a result of the Orders, AEFC was censured and ordered to cease and desist
from committing or causing any violations of certain provisions of the
Investment Advisers Act of 1940, the Investment Company Act of 1940, and
various Minnesota laws. Pursuant to the terms of the Orders, AEFC agreed to
pay disgorgement of $10 million and civil money penalties of $7 million. AEFC
also agreed to make presentations at least annually to its board of directors
and the relevant mutual funds' board that include an overview of policies and
procedures to prevent market timing, material changes to these policies and
procedures and whether disclosures related to market timing are consistent
with the SEC order and federal securities laws. AEFC also agreed to retain an
independent distribution consultant to assist in developing a plan for
distribution of all disgorgement and civil penalties ordered by the SEC in
accordance with various undertakings detailed at
http://www.sec.gov/litigation/admin/ia-2451.pdf. In addition, AEFC agreed to
complete and submit to the MDOC a compliance review of its procedures
regarding market timing within one year of the MDOC Order, including a summary
of actions taken to ensure compliance with applicable laws and regulations and
certification by a senior officer regarding compliance and supervisory
procedures.

Ameriprise Financial and its affiliates have cooperated with the SEC and the
MDOC in these legal proceedings, and have made regular reports to the
RiverSource Funds' Boards of Directors/Trustees.

Ameriprise Financial and certain of its affiliates have historically been
involved in a number of legal, arbitration and regulatory proceedings,
including routine litigation, class actions, and governmental actions,
concerning matters arising in connection with the conduct of their business
activities. Ameriprise Financial believes that the Funds are not currently the
subject of, and that neither Ameriprise Financial nor any of its affiliates
are the subject of, any pending legal, arbitration or regulatory proceedings
that are likely to have a material adverse effect on the Funds or the ability
of Ameriprise Financial or its affiliates to perform under their contracts
with the Funds. Ameriprise Financial is required to make 10-Q, 10-K and, as
necessary, 8-K filings with the Securities and Exchange Commission on legal
and regulatory matters that relate to Ameriprise Financial and its affiliates.
Copies of these filings may be obtained by accessing the SEC website at
www.sec.gov.

There can be no assurance that these matters, or the adverse publicity
associated with them, will not result in increased fund redemptions, reduced
sale of fund shares or other adverse consequences to the Funds. Further,
although we believe proceedings are not likely to have a material adverse
effect on the Funds or the ability of Ameriprise Financial or its affiliates
to perform under their contracts with the Funds, these proceedings are subject
to uncertainties and, as such, we are unable to estimate the possible loss or
range of loss that may result. An adverse outcome in one or more of these
proceedings could result in adverse judgments, settlements, fines, penalties
or other relief that could have a material adverse effect on the consolidated
financial condition or results of operations of Ameriprise Financial.

seasoned portfolio management team, the end result is a broadly diversified

PERFORMANCE SUMMARY

                            PERFORMANCE COMPARISON
                 For the six-month period ended Jan. 31, 2007

[THE FOLLOWING TABLE WAS REPRESENTED AS A BAR CHART IN THE PRINTED MATERIAL.]


                                                                     
RiverSource Large Cap Value Fund Class A (excluding sales charge)      +14.07%

Lipper Large-Cap Value Funds Index(2)                                  +12.96%

(1)   The Russell 1000 Value Index, an unmanaged index, measures the
      performance of those stocks in the Russell 1000 Index with lower
      price-to-book ratios and lower forecasted growth values. The index
      reflects reinvestment of all distributions and changes in market prices.

(2)   The Lipper Large-Cap Value Funds Index includes the 30 largest large-cap
      value funds tracked by Lipper Inc. The index's returns include net
      reinvested dividends. The Fund's performance is currently measured
      against this index for purposes of determining the performance incentive
      adjustment.


The performance information shown represents past performance and is not a
guarantee of future results. The investment return and principal value of your
investment will fluctuate so that your shares, when redeemed, may be worth
more or less than their original cost. Current performance may be lower or
higher than the performance information shown. You may obtain performance
information current to the most recent month-end by contacting your financial
institution or visiting riversource.com/funds.

The 5.75% sales charge applicable to Class A shares of the Fund is not
reflected in the bar chart. If reflected, returns would be lower than those
shown. The performance of other classes may vary from that shown because of
differences in expenses.

The indices do not reflect the effects of sales charges, expenses (excluding
Lipper) and taxes.

It is not possible to invest directly in an index.

6  RIVERSOURCE LARGE CAP VALUE FUND - 2007 SEMIANNUAL REPORT


QUESTIONS & ANSWERS WITH PORTFOLIO MANAGEMENT

Below, Portfolio Manager Robert Ewing discusses the Fund's results and
positioning for the six-month period.

Q:    How did RiverSource Large Cap Value Fund perform for the six-month
      period ended Jan. 31, 2007?

A:    RiverSource Large Cap Value Fund's Class A shares advanced 14.07%,
      excluding sales charge, for the six months ended Jan. 31, 2007. The
      Fund's benchmark, the Russell 1000(R) Value Index (Russell Index), rose
      13.43% during the period. The Fund's peer group, the Lipper Large-Cap
      Value Funds Index, gained 12.96% during the same time frame.

Q:    What factors most significantly affected performance for the period?

A:    U.S. stocks delivered double-digit gains during the past six months,
      supported by continued economic growth, corporate earnings and the
      Federal Reserve Board's decision to hold interest rates steady after a
      period of short-term rate increases. A notable market shift occurred
      during this six-month period as large-cap growth stocks outpaced
      large-cap value stocks. Both stock selection and sector allocations
      added to the Fund's return relative to the Russell Index. The
      information technology and consumer discretionary sectors made the
      largest positive contributions to the Fund's return.

      The Fund had a larger allocation to information technology than the
      Russell Index and that overweight added significant value. The Fund
      benefited from its emphasis on larger-cap technology companies such as
      Microsoft, IBM, Cisco Systems and Hewlett-Packard, which demonstrated
      very strong earnings growth and remained at historically attractive
      valuations.

      Stock selection in the consumer discretionary sector was favorable and
      the Fund's weighting, which was larger than the Russell Index, also
      added value. The Fund's emphasis on media stocks was especially
      beneficial. Specifically, holdings of News Corp., Viacom and Vivendi
      performed well as investors began to recognize their strong and
      consistent free cash flow trends.

      THE INFORMATION TECHNOLOGY AND CONSUMER DISCRETIONARY SECTORS MADE THE
      LARGEST POSITIVE CONTRIBUTIONS TO THE FUND'S RETURN.


- ------------------------------------------------------------------------------

RIVERSOURCE LARGE CAP VALUE FUND - 2007 SEMIANNUAL REPORT  7


QUESTIONS & ANSWERS

      Within the materials sector, the Fund's smaller-than-Russell Index
      position was a slight disadvantage when materials stocks outperformed
      during the period. While many commodity prices fell during the period,
      materials stocks continued to advance on strong merger and acquisition
      activity in the industry.

Q:    What changes did you make to the portfolio and how is it currently
      positioned?

A:    We sold selected stocks in the Fund's portfolio when valuations
      approached our target levels, taking some profits as a result. We
      reduced exposure to some financial stocks, such as mortgage lenders, on
      concerns of credit deterioration related to the current housing
      slowdown. Within the financials sector, we increased the portfolio's
      exposure to the insurance industry.

Q:    How do you plan to manage the Fund in the coming months?

A:    In the current environment, we see corporate profit margins at record
      levels, signs of slower global economic growth and a weaker U.S. housing
      market that could lead consumers to reduce their spending. All of these
      suggest that corporate profit growth is likely to decelerate.

      Given such a backdrop, we prefer to own high quality companies that are
      attractively valued. The difference between the valuations of
      traditional growth stocks and traditional value stocks has become quite
      small. We have focused on companies whose growth tends to be stable
      regardless of economic performance and on companies whose cyclical
      nature appears to be discounted in the stock price. As a result, the
      Fund's positions in health care and information technology are larger
      than the respective weightings within the Russell Index. We continue to
      find an increasing number of opportunities among large-cap companies
      which still appear inexpensive compared to their mid- and small-cap
      peers.

Any specific securities mentioned are for illustrative purposes only and are
not a complete list of securities that have increased or decreased in value.

8  RIVERSOURCE LARGE CAP VALUE FUND - 2007 SEMIANNUAL REPORT


FUND EXPENSES EXAMPLE
(UNAUDITED)

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads) on purchase payments; and (2) ongoing
costs, which may include management fees; distribution and service (12b-1)
fees; and other Fund fees and expenses. This example is intended to help you
understand your ongoing costs (in dollars) of investing in the Fund and to
compare these costs with the ongoing costs of investing in other mutual funds.
In addition to the ongoing expenses which the Fund bears directly, the Fund's
shareholders indirectly bear the expenses of the funds in which it invests
(also referred to as "acquired funds"), including affiliated and
non-affiliated pooled investment vehicles (including mutual funds and exchange
traded funds). The Fund's indirect expense from investing in the acquired
funds is based on the Fund's pro rata portion of the cumulative expenses
charged by the acquired funds using the acquired funds expense ratio as of the
most recent shareholder report.

The example is based on an investment of $1,000 invested at the beginning of
the period and held for the six months ended Jan. 31, 2007.

ACTUAL EXPENSES

The first line of the table provides information about actual account values
and actual expenses. You may use the information in this line, together with
the amount you invested, to estimate the expenses that you paid over the
period. 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
in the first line under the heading titled "Expenses paid during the period"
to estimate the expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES

The second line of the table provides information about hypothetical account
values and hypothetical expenses based on the Fund's actual expense ratio and
an assumed rate of return of 5% per year before expenses, which is not the
Fund's actual return. 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 the 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.


- ------------------------------------------------------------------------------

RIVERSOURCE LARGE CAP VALUE FUND - 2007 SEMIANNUAL REPORT  9


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). Therefore, the second line of 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.

(a)   Expenses are equal to the Fund's annualized expense ratio as indicated
      above, multiplied by the average account value over the period,
      multiplied by 184/365 (to reflect the one-half year period).

(b)   Based on the actual return for the six months ended Jan. 31, 2007:
      +14.07% for Class A, +13.55% for Class B, +13.50% for Class C, +14.30%
      for Class I and +14.07% for Class R4.

(c)   The actual values and expenses paid are not presented because Class R2,
      Class R3 and Class R5 do not have a full six months of history. The
      inception date of Class R2, Class R3 and Class R5 is Dec. 11, 2006.

(d)   In September 2006, the Board approved renaming Class Y as Class R4,
      terminating the shareholder servicing agreement, revising the fee
      structure under the transfer agent agreement from an account-based fee
      to an asset-based fee, and adopting a plan administration services
      agreement. In addition, the investment manager and its affiliates have
      contractually agreed to waive certain fees and to absorb certain
      expenses until July 31, 2007, unless sooner terminated at the discretion
      of the Fund's Board, such that net expenses, (excluding fees and
      expenses of acquired funds) before giving effect to any performance
      incentive adjustment, will not exceed 1.12% for Class R4. Any amounts
      waived will not be reimbursed by the Fund. These changes were effective
      Dec. 11, 2006. If these changes had been in place for the six-month
      period ended Jan. 31, 2007, actual and hypothetical expenses paid for
      Class R4 would have been the same as those presented in the above table.

NOTES TO INVESTMENTS IN SECURITIES

(a)   Securities are valued by procedures described in Note 1 to the financial
      statements.

(b)   Non-income producing.

(c)   Foreign security values are stated in U.S. dollars. At Jan. 31, 2007,
      the value of foreign securities represented 4.8% of net assets.

      do not have a legal claim on the company's assets.

(e)   Identifies issues considered to be illiquid as to their marketability
      (see Note 1 to the financial statements). These securities may be valued
      at fair value according to methods selected in good faith by the Fund's

RIVERSOURCE LARGE CAP VALUE FUND - 2007 SEMIANNUAL REPORT  21


NOTES TO FINANCIAL STATEMENTS

(Unaudited as to Jan. 31, 2007)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Fund is a series of RiverSource Large Cap Series, Inc. and is registered
under the Investment Company Act of 1940 (as amended) as a diversified,
open-end management investment company. RiverSource Large Cap Series, Inc. has
10 billion authorized shares of capital stock that can be allocated among the
separate series as designated by the Board. The Fund invests primarily in
equity securities of companies with a market capitalization greater than $5
billion.

The Fund offers Class A, Class B, Class C and Class R4 shares.

o     Class A shares are sold with a front-end sales charge.

o     Class B shares may be subject to a contingent deferred sales charge
      (CDSC) and automatically convert to Class A shares during the ninth year
      of ownership.

o     Class C shares may be subject to a CDSC.

o     Class R4 shares have no sales charge and are offered only to qualifying
      institutional investors.

In September 2006, the Board approved renaming Class Y as Class R4,
terminating the shareholder servicing agreement, revising the fee structure
under the transfer agent agreement from account-based to asset-based, and
adopting a plan administration services agreement. These changes were
effective Dec. 11, 2006.

The Fund offers an additional class of shares, Class I, exclusively to certain
institutional investors. Class I shares have no sales charge and are made
available through a separate prospectus supplement provided to investors
eligible to purchase the shares. At Jan. 31, 2007, Ameriprise Financial, Inc.
(Ameriprise Financial) and the affiliated funds-of-funds owned 100% of Class I
shares.

Effective Dec. 11, 2006, the Fund offers additional classes of shares, Class
R2, Class R3 and Class R5, offered to certain institutional investors. These
shares are sold without a front-end sales charge or CDSC. At Jan. 31, 2007,
Ameriprise Financial owned 100% of Class R2 and Class R3 shares.

At Jan. 31, 2007, Ameriprise Financial and the affiliated funds-of-funds owned
approximately 16% of the total outstanding Fund shares.

All classes of shares have identical voting, dividend and liquidation rights.
Class specific expenses (e.g., distribution and service fees, transfer agency
fees, plan administration fees) differ among classes. Income, expenses (other
than class specific expenses) and realized and unrealized gains or losses on
investments are allocated to each class of shares based upon its relative net
assets.

22  RIVERSOURCE LARGE CAP VALUE FUND - 2007 SEMIANNUAL REPORT


The Fund's significant accounting policies are summarized below:

USE OF ESTIMATES

Preparing financial statements that conform to U.S. generally accepted
accounting principles requires management to make estimates (e.g., on assets,
liabilities and contingent assets and liabilities) that could differ from
actual results.

VALUATION OF SECURITIES

All securities are valued at the close of each business day. Securities traded
on national securities exchanges or included in national market systems are
valued at the last quoted sales price. Debt securities are generally traded in
the over-the-counter market and are valued at a price that reflects fair value
as quoted by dealers in these securities or by an independent pricing service.
Pursuant to procedures adopted by the Board of Directors of the funds,
Ameriprise Financial utilizes Fair Value Pricing (FVP). FVP determinations are
made in good faith in accordance with these procedures. If a development or
event is so significant that there is a reasonably high degree of certainty
that the effect of the development or event has actually caused the closing
price to no longer reflect the actual value, the closing prices, as determined
at the close of the applicable foreign market, may be adjusted to reflect the
fair value of the affected foreign securities as of the close of the New York
Stock Exchange. Significant events include material movements in the U.S.
securities markets prior to the opening of foreign markets on the following
trading day. FVP results in an estimated price that reasonably reflects the
current market conditions in order to value the portfolio holdings such that
shareholder transactions receive a fair net asset value. Short-term securities
maturing in more than 60 days from the valuation date are valued at the market
price or approximate market value based on current interest rates; those
maturing in 60 days or less are valued at amortized cost.

ILLIQUID SECURITIES

At Jan. 31, 2007, investments in securities included issues that are illiquid
which the Fund currently limits to 10% of net assets, at market value, at the
time of purchase. The aggregate value of such securities at Jan. 31, 2007 was
$161,349 representing 0.16% of net assets. These securities are valued at fair
value according to methods selected in good faith by the Board. According to
board guidelines, certain unregistered securities are determined to be liquid
and are not included within the 10% limitation specified above. Assets are
liquid if they can be sold or disposed of in the ordinary course of business
within seven days at approximately the value at which the asset is valued by
the Fund.


- ------------------------------------------------------------------------------

RIVERSOURCE LARGE CAP VALUE FUND - 2007 SEMIANNUAL REPORT  23


OPTION TRANSACTIONS

To produce incremental earnings, protect gains, and facilitate buying and
selling of securities for investments, the Fund may buy and write options
traded on any U.S. or foreign exchange or in the over-the-counter market where
completing the obligation depends upon the credit standing of the other party.
The Fund also may buy and sell put and call options and write covered call
options on portfolio securities as well as write cash-secured put options. The
risk in writing a call option is that the Fund gives up the opportunity for
profit if the market price of the security increases. The risk in writing a
put option is that the Fund may incur a loss if the market price of the
security decreases and the option is exercised. The risk in buying an option
is that the Fund pays a premium whether or not the option is exercised. The
Fund also has the additional risk of being unable to enter into a closing
transaction if a liquid secondary market does not exist.

Option contracts are valued daily at the closing prices on their primary
exchanges and unrealized appreciation or depreciation is recorded. The Fund
will realize a gain or loss when the option transaction expires or closes.
When an option is exercised, the proceeds on sales for a written call option,
the purchase cost for a written put option or the cost of a security for a
purchased put or call option is adjusted by the amount of premium received or
paid.

FUTURES TRANSACTIONS

To gain exposure to or protect itself from market changes, the Fund may buy
and sell financial futures contracts traded on any U.S. or foreign exchange.
The Fund also may buy and write put and call options on these futures
contracts. Risks of entering into futures contracts and related options
include the possibility of an illiquid market and that a change in the value
of the contract or option may not correlate with changes in the value of the
underlying securities.

Upon entering into a futures contract, the Fund is required to deposit either
cash or securities in an amount (initial margin) equal to a certain percentage
of the contract value. Subsequent payments (variation margin) are made or
received by the Fund each day. The variation margin payments are equal to the
daily changes in the contract value and are recorded as unrealized gains and
losses. The Fund recognizes a realized gain or loss when the contract is
closed or expires.


- ------------------------------------------------------------------------------

24  RIVERSOURCE LARGE CAP VALUE FUND - 2007 SEMIANNUAL REPORT


FOREIGN CURRENCY TRANSLATIONS AND FOREIGN CURRENCY CONTRACTS

Securities and other assets and liabilities denominated in foreign currencies
are translated daily into U.S. dollars. Foreign currency amounts related to
the purchase or sale of securities and income and expenses are translated at
the exchange rate on the transaction date. The effect of changes in foreign
exchange rates on realized and unrealized security gains or losses is
reflected as a component of such gains or losses. In the statement of
operations, net realized gains or losses from foreign currency transactions,
if any, may arise from sales of foreign currency, closed forward contracts,
exchange gains or losses realized between the trade date and settlement date
on securities transactions, and other translation gains or losses on
dividends, interest income and foreign withholding taxes.

The Fund may enter into forward foreign currency exchange contracts for
operational purposes and to protect against adverse exchange rate fluctuation.
The net U.S. dollar value of foreign currency underlying all contractual
commitments held by the Fund and the resulting unrealized appreciation or
depreciation are determined using foreign currency exchange rates from an
independent pricing service. The Fund is subject to the credit risk that the
other party will not complete its contract obligations.

GUARANTEES AND INDEMNIFICATIONS

Under the Fund's organizational documents, its officers and directors are
indemnified against certain liabilities arising out of the performance of
their duties to the Fund. In addition, certain of the Fund's contracts with
its service providers contain general indemnification clauses. The Fund's
maximum exposure under these arrangements is unknown since the amount of any
future claims that may be made against the Fund cannot be determined and the
Fund has no historical basis for predicting the likelihood of any such claims.

FEDERAL TAXES

The Fund's policy is to comply with Subchapter M of the Internal Revenue Code
that applies to regulated investment companies and to distribute substantially
all of its taxable income to shareholders. No provision for income or excise
taxes is thus required.

Net investment income (loss) and net realized gains (losses) may differ for
financial statement and tax purposes primarily because of deferred losses on
certain futures contracts, the recognition of certain foreign currency gains
(losses) as ordinary income (loss) for tax purposes and losses deferred due to
"wash sale" transactions. The 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. Also, due to the
timing of dividend distributions, the fiscal year in which amounts are
distributed may differ from the year that the income or realized gains
(losses) were recorded by the Fund.

RECENT ACCOUNTING PRONOUNCEMENTS

On Sept. 20, 2006, the Financial Accounting Standards Board ("FASB") released
Statement of Financial Accounting Standards No. 157 "Fair Value Measurements"
("SFAS 157"). SFAS 157 establishes an authoritative definition of fair value,
sets out a framework for measuring fair value, and requires additional
disclosures about fair-value measurements. The application of SFAS 157 is
required for fiscal years beginning after Nov. 15, 2007 and interim periods
within those fiscal years. The impact of SFAS 157 on the Fund's financial
statements is being evaluated.

In June 2006, the Financial Accounting Standards Board (FASB) issued FASB
Interpretation 48 (FIN 48), "Accounting for Uncertainty in Income Taxes." FIN
48 clarifies the accounting for uncertainty in income taxes recognized in
accordance with FASB Statement 109, "Accounting for Income Taxes." FIN 48
prescribes a two-step process to recognize and measure a tax position taken or
expected to be taken in a tax return. The first step is to determine whether a
tax position has met the more-likely-than-not recognition threshold and the
second step is to measure a tax position that meets the threshold to determine
the amount of benefit to recognize. FIN 48 also provides guidance on
derecognition, classification, interest and penalties, accounting in interim
periods, disclosure and transition. FIN 48 is effective for fiscal years
beginning after Dec. 15, 2006. Tax positions of the Fund are being evaluated
to determine the impact, if any, to the Fund. The adoption of FIN 48 is not
anticipated to have a material impact on the Fund.

DIVIDENDS TO SHAREHOLDERS

An annual dividend from net investment income, declared and paid at the end of
the calendar year, when available, is reinvested in additional shares of the
Fund at net asset value or payable in cash. Capital gains, when available, are
distributed along with the income dividend.

OTHER

Security transactions are accounted for on the date securities are purchased
or sold. Dividend income is recognized on the ex-dividend date and interest
income, including amortization of premium, market discount and original issue
discount using the effective interest method, is accrued daily.

2. EXPENSES AND SALES CHARGES

Under an Investment Management Services Agreement, RiverSource Investments,
LLC (the Investment Manager) determines which securities will be purchased,
held or sold. The management fee is a percentage of the Fund's average daily
net assets that declines from 0.60% to 0.375% annually as the Fund's assets
increase. The fee may be adjusted upward or downward by a performance
incentive adjustment based on a comparison of the performance of Class A
shares of the Fund to the Lipper Large-Cap Value Funds Index. In certain
circumstances, the Board may approve a change in the index. The maximum
adjustment is 0.12% per year. If the performance difference is less than
0.50%, the adjustment will be zero. The adjustment decreased the fee by $2,359
for the six months ended Jan. 31, 2007.

Under an Administrative Services Agreement, the Fund pays Ameriprise Financial
a fee for administration and accounting services at a percentage of the Fund's
average daily net assets that declines from 0.06% to 0.03% annually as the
Fund's assets increase.

Other expenses in the amount of $2,819 are for, among other things, certain
expenses of the Fund or the Board including: Fund boardroom and office
expense, employee compensation, employee health and retirement benefits, and
certain other expenses. Payment of these Fund and Board expenses is
facilitated by a company providing limited administrative services to the Fund
and the Board.

Compensation of Board members includes, for the former Board Chair,
compensation as well as retirement benefits. Certain other aspects of the
former Board Chair's compensation, including health benefits and payment of
certain other expenses, are included under other expenses.

Under a Deferred Compensation Plan (the Plan), non-interested board members
may defer receipt of their compensation. Deferred amounts are treated as
though equivalent dollar amounts had been invested in shares of the Fund or
other RiverSource funds. The Fund's liability for these amounts is adjusted
for market value changes and remains in the Fund until distributed in
accordance with the Plan.

Professional fees include fees paid by the Fund for legal services and
independent auditor services.

Under a Transfer Agency Agreement, RiverSource Service Corporation (the
Transfer Agent) maintains shareholder accounts and records. The Fund pays the
Transfer Agent an annual fee per shareholder account for this service as
follows:

o     Class A $19.50

o     Class B $20.50

o     Class C $20.00

Effective Dec. 11, 2006, as part of the Board's approval to rename Class Y as
Class R4, the fee structure under the Transfer Agency Agreement was revised
from an account-based fee for Class Y to an asset-based fee for Class R4. The
Fund will pay the Transfer Agent an annual asset-based fee at a rate of 0.05%
of the Fund's average daily net assets, attributable to Class R4 shares. Prior
to Dec. 11, 2006, the Fund paid the Transfer Agent an annual account-based fee
of $17.50 per shareholder account.

In addition, with the introduction of Class R2, Class R3 and Class R5 shares,
the Fund will pay the Transfer Agent an annual asset-based fee at a rate of
0.05% of the Funds average daily net assets attributable to Class R2, Class R3
and Class R5 shares.

Prior to Dec. 11, 2006, Class I paid a transfer agency fee at an annual rate
per shareholder account of $1. This amount is included in the transfer agency
fee on the statement of operations. Effective Dec. 11, 2006, this fee was
eliminated.

The Transfer Agent charges an annual closed account fee of $5 per inactive
account, charged on a pro rata basis for 12 months from the date the account
becomes inactive. These fees are included in the transfer agency fees on the
statement of operations.

The Fund has agreements with Ameriprise Financial Services, Inc. and
RiverSource Distributors, Inc. (collectively, the Distributor) for
distribution and shareholder services. Under a Plan and Agreement of
Distribution pursuant to Rule 12b-1, the Fund pays a fee at an annual rate of
up to 0.25% of the Fund's average daily net assets attributable to Class A and
Class R3 shares, a fee at an annual rate of up to 0.50% of the Fund's average
daily net assets attributable to Class R2 shares and a fee at an annual rate
of up to 1.00% of the Fund's average daily net assets attributable to Class B
and Class C shares.

Beginning Dec. 11, 2006, a new Plan Administration Services Agreement was
adopted for the restructured Class R4 and the introduction of Class R2 and
Class R3. The fee is calculated at a rate of 0.25% of the Fund's average daily
net assets attributable to Class R2, Class R3 and Class R4 shares.

Prior to Dec. 11, 2006, under a Shareholder Service Agreement, the Fund paid
the Distributor a fee for service provided to shareholders by the Distributor
and other servicing agents with respect to those shares. The fee was
calculated at a rate of 0.10% of the Fund's average daily net assets
attributable to Class Y shares. Effective Dec. 11, 2006, this agreement was
terminated.

Sales charges received by the Distributor for distributing Fund shares were
$35,406 for Class A, $11,478 for Class B and $26 for Class C for the six
months ended Jan. 31, 2007.

In addition to the fees and expenses which the Fund bears directly, the Fund
indirectly bears a pro rata share of the fees and expenses of the funds in
which it invests (also referred to as "acquired funds"), including affiliated
and non-affiliated pooled investment vehicles (including mutual funds and
exchange traded funds). Because the acquired funds have varied expense and fee
levels and the Fund may own different proportions of acquired funds at
different times, the amount of fees and expenses incurred indirectly by the
Fund will vary.

For the six months ended Jan. 31, 2007, the Investment Manager and its
affiliates waived certain fees and expenses to 1.29% for Class A, 2.05% for
Class B, 2.05% for Class C, 0.91% for Class I, 1.70% for Class R2, 1.45% for
Class R3, 1.12% for Class R4, and 0.96% for Class R5. Of these waived fees and
expenses, the transfer agency fees waived for Class A, Class B, Class C, and
Class R4 were $18,213, $5,907, $320, and $10, respectively, and the management
fees waived at the Fund level were $190. In addition, the Investment Manager
and its affiliates have agreed to waive certain fees and expenses until July
31, 2007, unless sooner terminated by the Board, such that net expenses
(excluding fees and expenses of acquired funds), before giving effect to any
performance incentive adjustment, will not exceed 1.29% for Class A, 2.05% for
Class B, 2.06% for Class C, 0.94% for Class I, 1.69% for Class R2, 1.44% for
Class R3, 1.12% for Class R4, and 0.94 % for Class R5 of the Fund's average
daily net assets.

During the six months ended Jan. 31, 2007, the Fund's custodian and transfer
agency fees were reduced by $7,372 as a result of earnings and bank fee
credits from overnight cash balances. The Fund also pays custodian fees to
Ameriprise Trust Company, an affiliate of Ameriprise Financial.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $16,932,254 and $27,340,521, respectively, for the six

5. AFFILIATED MONEY MARKET FUND

The Fund may invest its daily cash balance in RiverSource Short-Term Cash
Fund, a money market fund established for the exclusive use of the RiverSource
funds and other institutional clients of RiverSource Investments.

6. BANK BORROWINGS

The Fund has a revolving credit agreement with a syndicate of banks headed by
JPMorgan Chase Bank, N.A. (JPMCB), whereby the Fund may borrow for the
temporary funding of shareholder redemptions or for other temporary or
emergency purposes. The agreement went into effect Sept. 19, 2006. The Fund
must maintain asset coverage for borrowings of at least 300%. The agreement,
which enables the Fund to participate with other RiverSource funds, permits
borrowings up to $500 million, collectively. Interest is charged to each Fund
based on its borrowings at a rate equal to either the higher of the Federal
Funds Effective Rate plus 0.40% or the JPMCB Prime Commercial Lending Rate.
Borrowings are payable within 60 days after such loan is executed. The Fund
also pays a commitment fee equal to its pro rata share of the amount of the
credit facility at a rate of 0.06% per annum. Prior to this agreement, the
Fund paid a commitment fee equal to its pro rata share of the amount of the
credit facility at a rate of 0.07% per annum. The Fund had no borrowings under
the facility outstanding during the six months ended Jan. 31, 2007.

7. INFORMATION REGARDING PENDING AND SETTLED LEGAL PROCEEDINGS

In June 2004, an action captioned John E. Gallus et al. v. American Express
Financial Corp. and American Express Financial Advisors Inc., was filed in the
United States District Court for the District of Arizona. The plaintiffs
allege that they are investors in several American Express Company mutual
funds and they purport to bring the action derivatively on behalf of those
funds under the Investment Company Act of 1940. The plaintiffs allege that
fees allegedly paid to the defendants by the funds for investment advisory and
administrative services are excessive. The plaintiffs seek remedies including
restitution and rescission of investment advisory and distribution agreements.
The plaintiffs voluntarily agreed to transfer this case to the United States
District Court for the District of Minnesota. In response to our motion to
dismiss the complaint, the Court dismissed one of plaintiffs' four claims and
granted plaintiffs limited discovery. Discovery is currently set to end in
March 2007.


- ------------------------------------------------------------------------------

RIVERSOURCE LARGE CAP VALUE FUND - 2007 SEMIANNUAL REPORT  31


In December 2005, without admitting or denying the allegations, American
Express Financial Corporation (AEFC, which is now known as Ameriprise
Financial, Inc. (Ameriprise Financial)), the parent company of RiverSource
Investments, LLC (RiverSource Investments), entered into settlement agreements
with the Securities and Exchange Commission (SEC) and Minnesota Department of
Commerce (MDOC) related to market timing activities. In connection with these
matters, the SEC and MDOC issued orders (the Orders) alleging that AEFC
violated certain provisions of the federal and Minnesota securities laws by
failing to adequately disclose market timing activities by allowing certain
identified market timers to continue to market time contrary to disclosures in
mutual fund and variable annuity product prospectuses. The Orders also alleged
that AEFC failed to implement procedures to detect and prevent market timing
in 401(k) plans for employees of AEFC and related companies and failed to
adequately disclose that there were no such procedures. Pursuant to the MDOC
Order, the MDOC also alleged that AEFC allowed inappropriate market timing to
occur by failing to have written policies and procedures and failing to
properly supervise its employees.

As a result of the Orders, AEFC was censured and ordered to cease and desist
from committing or causing any violations of certain provisions of the
Investment Advisers Act of 1940, the Investment Company Act of 1940, and
various Minnesota laws. Pursuant to the terms of the Orders, AEFC agreed to
pay disgorgement of $10 million and civil money penalties of $7 million. AEFC
also agreed to make presentations at least annually to its board of directors
and the relevant mutual funds' board that include an overview of policies and
procedures to prevent market timing, material changes to these policies and
procedures and whether disclosures related to market timing are consistent
with the SEC order and federal securities laws. AEFC also agreed to retain an
independent distribution consultant to assist in developing a plan for
distribution of all disgorgement and civil penalties ordered by the SEC in
accordance with various undertakings detailed at
http://www.sec.gov/litigation/admin/ia-2451.pdf. In addition, AEFC agreed to
complete and submit to the MDOC a compliance review of its procedures
regarding market timing within one year of the MDOC Order, including a summary
of actions taken to ensure compliance with applicable laws and regulations and
certification by a senior officer regarding compliance and supervisory
procedures.

Ameriprise Financial and its affiliates have cooperated with the SEC and the
MDOC in these legal proceedings, and have made regular reports to the
RiverSource Funds' Boards of Directors/Trustees.


- ------------------------------------------------------------------------------

32  RIVERSOURCE LARGE CAP VALUE FUND - 2007 SEMIANNUAL REPORT


Ameriprise Financial and certain of its affiliates have historically been
involved in a number of legal, arbitration and regulatory proceedings,
including routine litigation, class actions, and governmental actions,
concerning matters arising in connection with the conduct of their business
activities. Ameriprise Financial believes that the Funds are not currently the
subject of, and that neither Ameriprise Financial nor any of its affiliates
are the subject of, any pending legal, arbitration or regulatory proceedings
that are likely to have a material adverse effect on the Funds or the ability
of Ameriprise Financial or its affiliates to perform under their contracts
with the Funds. Ameriprise Financial is required to make 10-Q, 10-K and, as
necessary, 8-K filings with the Securities and Exchange Commission on legal
and regulatory matters that relate to Ameriprise Financial and its affiliates.
Copies of these filings may be obtained by accessing the SEC website at
www.sec.gov.

There can be no assurance that these matters, or the adverse publicity
associated with them, will not result in increased fund redemptions, reduced
sale of fund shares or other adverse consequences to the Funds. Further,
although we believe proceedings are not likely to have a material adverse
effect on the Funds or the ability of Ameriprise Financial or its affiliates
to perform under their contracts with the Funds, these proceedings are subject
to uncertainties and, as such, we are unable to estimate the possible loss or
range of loss that may result. An adverse outcome in one or more of these
proceedings could result in adverse judgments, settlements, fines, penalties
or other relief that could have a material adverse effect on the consolidated
financial condition or results of operations of Ameriprise Financial.
