Dear Fellow Shareholders,

2008 was an unprecedented year in many ways. Investors watched the precipitous
decline in all the major U.S. and international equity indexes as concerns about
the economy gave way to fear and selling of securities. In response to
substantial losses in the markets and weakening economic indicators, the
government stepped in swiftly and aggressively to encourage liquidity and credit
availability in an attempt to make credit markets function. By the end of the
calendar year, these actions still needed time to gain traction in the markets.

During a severe economic environment like the one we are experiencing, it is
essential that investors try not to let short-term losses in the market distract
from a long-term investment plan. Such discipline may be easier said than done
in the presence of negative news in the media. However, the financial choices
you make today -- practicing patience or locking in losses -- will influence
your portfolio's performance.

GETTING BACK ON TRACK
Whether you look at the glass as half empty or half full, every broad based
market decline creates investment opportunities. The financial markets are
expected to recover, although it is impossible to know when. In the meantime,
make sure your portfolio is positioned to benefit from the next sources of
growth.

Market recoveries often occur before the reported end of a recession. If you
wait for validation of economic recovery before reinvesting in the markets, you
may well miss out on market returns associated with an economic rebound.

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 expense ratio of each of the acquired funds as of the acquired fund's
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, 2009.

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.

FAIR VALUE MEASUREMENTS


Statement of Financial Accounting Standards No. 157 (SFAS 157) seeks to
implement more uniform reporting relating to the fair valuation of securities
for financial statement purposes. Mutual funds are required to implement the
requirements of this standard for fiscal years beginning after Nov. 15, 2007.
While uniformity of presentation is the objective of the standard, it is likely
that there may be a range of practices utilized and it may be some period of
time before industry practices become more uniform. For this reason care should
be exercised in interpreting this information and/or using it for comparison
with other mutual funds.

Various inputs are used in determining the value of the Fund's investments.
These inputs are summarized in the three broad levels listed below:

     - Level 1 -- quoted prices in active markets for identical securities

     - Level 2 -- other significant observable inputs (including quoted prices
       for similar securities, interest rates, prepayment speeds, credit risks,
       etc.)

     - Level 3 -- significant unobservable inputs (including the Fund's own
       assumptions in determining the fair value of investments)

Observable inputs are those based on market data obtained from sources
independent of the fund, and unobservable inputs reflect the fund's own
assumptions based on the best information available. The input levels are not
necessarily an indication of the risk or liquidity associated with investments
at that level.

The following table is a summary of the inputs used to value the Fund's
investments as of Jan. 31, 2009:

(UNAUDITED AS TO JAN. 31, 2009)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

RiverSource Large Cap Equity Fund (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 of
Directors (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, Class I, Class R2, Class R3, Class R4
and Class R5 shares.

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

- -  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.

- -  Class C shares may be subject to a CDSC.

- -  Class I, Class R2, Class R3, Class R4 and Class R5 shares are sold without a
   front-end sales charge or CDSC and are offered to qualifying institutional
   investors.

At Jan. 31, 2009, RiverSource Investments, LLC (RiverSource Investments or the
Investment Manager) and the RiverSource affiliated funds-of-funds, owned 100% of
Class I shares and the Investment Manager owned 100% of Class R2 and Class R3
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 services 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.

                 RIVERSOURCE LARGE CAP EQUITY FUND -- 2009 SEMIANNUAL REPORT  39



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------


VALUATION OF SECURITIES
Effective Aug. 1, 2008, the Fund adopted Statement of Financial Accounting
Standards No. 157 "Fair Value Measurements" (SFAS 157). SFAS 157 establishes an
authoritative definition of fair value, sets out a hierarchy for measuring fair
value, and requires additional disclosures about the inputs used to develop the
measurements of fair value and the effect of certain measurements reported in
the Statement of Operations for a fiscal period. There was no impact to the
Fund's net assets or results of operations upon adoption. The fair valuation
measurements disclosure can be found following the Notes to Portfolio of
Investments.

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.
When market quotes are not readily available, the pricing service, in
determining fair values of debt securities, takes into consideration such
factors as current quotations by broker/dealers, coupon, maturity, quality, type
of issue, trading characteristics, and other yield and risk factors it deems
relevant in determining valuations. Foreign securities are valued based on
quotations from the principal market in which such securities are normally
traded. The procedures adopted by the Board generally contemplate the use of
fair valuation in the event that price quotations or valuations are not readily
available, price quotations or valuations from other sources are not reflective
of market value and thus deemed unreliable, or a significant event has occurred
in relation to a security or class of securities (such as foreign securities)
that is not reflected in price quotations or valuations from other sources. A
fair value price is a good faith estimate of the value of a security at a given
point in time.

Many securities markets and exchanges outside the U.S. close prior to the close
of the New York Stock Exchange and therefore the closing prices for securities
in such markets or on such exchanges may not fully reflect events that occur
after such close but before the close of the New York Stock Exchange, including
significant movements in the U.S. market after foreign exchanges have closed.
Accordingly, in those situations, Ameriprise Financial, Inc. (Ameriprise
Financial), parent company of the Investment Manager, as administrator to the
Fund, will fair value foreign securities pursuant to procedures adopted by the
Board, including utilizing a third party pricing service to determine these fair
values. These procedures take into account multiple factors, including movements
in the U.S. securities markets, to determine a good faith estimate that
reasonably reflects the current market conditions as of the close of the New
York Stock

- --------------------------------------------------------------------------------
40  RIVERSOURCE LARGE CAP EQUITY FUND -- 2009 SEMIANNUAL REPORT



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




Exchange. Swap transactions are valued through an authorized pricing service,
broker, or an internal model.

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, which
approximates fair value.

ILLIQUID SECURITIES
At Jan. 31, 2009, investments in securities included issues that are illiquid
which the Fund currently limits to 15% of net assets, at market value, at the
time of purchase. The aggregate value of such securities at Jan. 31, 2009 was
$29,291,575 representing 1.38% of net assets. Certain illiquid securities may be
valued by management at fair value according to procedures approved, in good
faith, by the Board. According to Board guidelines, certain unregistered
securities are determined to be liquid and are not included within the 15%
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.
Cash collateral may be collected by the Fund to secure certain over-the-counter
options (OTC options) trades. Cash collateral held by the Fund for such option
trades must be returned to the counterparty upon closure, exercise or expiration
of the contract. 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. Option
contracts, including OTC option contracts, with no readily available market
value are valued using quotations obtained from independent brokers as of the
close of the New York Stock Exchange. The Fund will realize a gain or loss when
the option

- --------------------------------------------------------------------------------
                 RIVERSOURCE LARGE CAP EQUITY FUND -- 2009 SEMIANNUAL REPORT  41



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------



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. At Jan. 31, 2009, the Fund had no
outstanding option contracts.

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.

Futures and options on futures are valued daily based upon the last sale price
at the close of the market on the principal exchange on which they are traded.
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 FORWARD 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, 2009, foreign currency holdings were entirely
comprised of European monetary units.

The Fund may enter into forward foreign currency 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

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

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




counterparty will not complete its contract obligations. At Jan. 31, 2009, the
Fund had no outstanding forward foreign currency contracts.

TOTAL RETURN EQUITY SWAP TRANSACTIONS
The Fund may enter into swap agreements to gain exposure to 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. 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 recorded 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. At
Jan. 31, 2009, the Fund had no outstanding total return equity swap contracts.

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.

NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------


Financial Accounting Standards Board (FASB) Interpretation 48 (FIN 48),
"Accounting for Uncertainty in Income Taxes," clarifies the accounting for
uncertainty in income taxes recognized in accordance with FASB Statement 109,
"Accounting for Income Taxes." FIN 48 provides guidance for how uncertain tax
positions should be recognized, measured, presented and disclosed in the
financial statements. Management of the Fund has concluded that there are no
significant uncertain tax positions that would require recognition in the
financial statements. Generally, the tax authorities can examine all the tax
returns filed for the last three years.

Net investment income (loss) and net realized gains (losses) may differ for
financial statement and tax purposes primarily because of futures and options
contracts, foreign currency transactions, recognition of unrealized appreciation
(depreciation) for certain derivative investments, re-characterization of REIT
distributions, investments in partnerships, post-October losses and losses
deferred due to wash sales. 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
The Fund has adopted FASB Staff Position No. 133-1 and FIN No. 45-4 (FSP FAS
133-1 and FIN 45-4), "Disclosures about Credit Derivatives and Certain
Guarantees: An Amendment of FASB Statement No. 133 and FASB Interpretation No.
45". The amendments to FSP FAS 133-1 and FIN 45-4 require enhanced disclosures
about a fund's derivatives and guarantees. Funds are required to provide
enhanced disclosures about (a) how and why a fund uses derivative instruments,
(b) how derivative instruments and related hedged items are accounted for under
SFAS 133 and its related interpretations, (c) how derivative instruments and
related hedged items affect a fund's financial position, financial performance,
and cash flows and (d) the current status of the payment/performance risk of the
credit derivative. The amendments to FSP FAS 133-1 and FIN 45-4 also require
additional disclosures about the current status of the payment/performance risk
of a guarantee. At Jan. 31, 2009, the Fund did not own nor was it a party to any
credit derivative contracts within the scope of these amendments.

In March 2008, the FASB issued Statement of Financial Accounting Standards No.
161 (SFAS 161), "Disclosures about Derivative Instruments and Hedging
Activities -- an amendment of FASB Statement No. 133," which requires enhanced
disclosures about a fund's derivative and hedging activities. SFAS 161

- --------------------------------------------------------------------------------
44  RIVERSOURCE LARGE CAP EQUITY FUND -- 2009 SEMIANNUAL REPORT



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




is effective for financial statements issued for fiscal years and interim
periods beginning after Nov. 15, 2008. As of Jan. 31, 2009, management does not
believe the adoption of SFAS 161 will impact the financial statement amounts;
however, additional footnote disclosures may be required about the use of
derivative instruments and hedging items.

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.

SECURITY LITIGATION SETTLEMENTS
Litigation proceeds from Enron Corp. related to portfolio securities no longer
included in the portfolio are recorded as realized gains. Proceeds received
during the six months ended Jan. 31, 2009 were $589,084.

2. EXPENSES AND SALES CHARGES

INVESTMENT MANAGEMENT SERVICES FEES
Under an Investment Management Services Agreement, 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 determined monthly by
measuring the percentage difference over a rolling 12-month period between the
annualized performance of one Class A share of the Fund and the annualized
performance of 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 decreased the management fee by $2,700,703 for the six
months ended Jan. 31, 2009. The management fee for the six months ended Jan. 31,
2009 was 0.39% of the Fund's average daily net assets, including the adjustment
under the terms of the performance incentive arrangement.

                 RIVERSOURCE LARGE CAP EQUITY FUND -- 2009 SEMIANNUAL REPORT  45



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------


ADMINISTRATIVE SERVICES FEES
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. The fee for the six months ended Jan. 31, 2009 was 0.05%
of the Fund's average daily net assets.

OTHER FEES
Other expenses 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. For the six months ended Jan.
31, 2009, other expenses paid to this company were $14,607.

COMPENSATION OF BOARD MEMBERS
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.

TRANSFER AGENCY FEES
Under a Transfer Agency Agreement, RiverSource Service Corporation (the Transfer
Agent) maintains shareholder accounts and records. The Fund pays the Transfer
Agent an annual account-based fee at a rate equal to $19.50 for Class A, $20.50
for Class B and $20.00 for Class C for this service. The Fund also pays 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, Class R4 and Class
R5 shares.

The Transfer Agent charges an annual 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.

PLAN ADMINISTRATION SERVICES FEES
Under a Plan Administration Services Agreement with the Transfer Agent, the Fund
pays an annual fee at a rate of 0.25% of the Fund's average daily net assets
attributable to Class R2, Class R3 and Class R4 shares for the provision of
various administrative, recordkeeping, communication and educational services.

DISTRIBUTION FEES
The Fund has an agreement with RiverSource Distributors, Inc. and RiverSource
Fund 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.
For Class B and Class C shares, up to 0.75% of the fee is reimbursed for
distribution expenses.

The amount of distribution expenses incurred by the Distributor and not yet
reimbursed ("unreimbursed expense") was approximately $11,663,000 and $169,000
for Class B and Class C shares, respectively. These amounts are based on the
most recent information available as of Jan. 31, 2009, and may be recovered from
future payments under the distribution plan or CDSC. To the extent the
unreimbursed expense has been fully recovered, the distribution fee is reduced.

SALES CHARGES
Sales charges received by the Distributor for distributing Fund shares were
$970,964 for Class A, $188,560 for Class B and $799 for Class C for the six
months ended Jan. 31, 2009.

EXPENSES WAIVED/REIMBURSED BY THE INVESTMENT MANAGER AND ITS AFFILIATES
For the six months ended Jan. 31, 2009, the Investment Manager and its
affiliates waived/reimbursed certain fees and expenses such that net expenses
(excluding fees and expenses of acquired funds*), including the adjustment under

Class R3...........................................     4
Class R4...........................................   917
</Table>


The management fees waived/reimbursed at the Fund level were $951,738.

The Investment Manager and its affiliates have contractually agreed to waive
certain fees and expenses until July 31, 2009, 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 the following percentage of the Fund's average daily net assets:

<Table>

Class R3............................................  1.17
Class R4............................................  0.90
Class R5............................................  0.67
</Table>


*   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.

BANK FEE CREDITS
During the six months ended Jan. 31, 2009, the Fund's transfer agency fees were
reduced by $27,696 as a result of bank fee credits from overnight cash balances.

CUSTODIAN FEES
Effective Dec. 15, 2008, the fund pays custodian fees to JPMorgan Chase Bank,
N.A. Prior to Dec. 15, 2008, the Fund paid custodian fees amounting to $160,746
to Ameriprise Trust Company, a subsidiary of Ameriprise Financial.

5. LENDING OF PORTFOLIO SECURITIES

Effective Dec. 1, 2008, the Fund has entered into a Master Securities Lending
Agreement ("the Agreement") with JPMorgan Chase Bank, National Association
("JPMorgan"). The Agreement authorizes JPMorgan as lending agent to lend
securities to authorized borrowers on behalf of the Fund. Pursuant to the
Agreement, all loaned securities are initially collateralized in an amount
equivalent to 102% (for securities denominated in U.S. dollars) or 105% (for all
other securities) of the value of the loaned securities, including accrued
interest in the case of fixed income securities. Collateral is maintained over
the life of the loan thereafter in an amount not less than 100% of the market
value of loaned

- --------------------------------------------------------------------------------
                 RIVERSOURCE LARGE CAP EQUITY FUND -- 2009 SEMIANNUAL REPORT  49



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------



securities, as determined at the close of each business day, except to the
extent that a collateral shortfall is due to a diminution in the market value of
authorized investments in which cash collateral is invested. Any additional
collateral required to maintain those levels due to market fluctuations of the
loaned securities is delivered the following business day. Collateral is either
in the form of cash or U.S. government securities. Cash collateral received is
invested by the lending agent on behalf of the Fund into authorized investments
pursuant to the Agreement. The investments made with the cash collateral are
listed on the Portfolio of Investments and the value of cash collateral received
at period end is disclosed on the Statement of Assets and Liabilities along with
the related obligation to return the collateral upon return of the securities
loaned. At Jan. 31, 2009, securities valued at $190,109,786 were on loan secured
by cash collateral of $203,391,339 invested in short-term securities or cash
equivalents.

Pursuant to the Agreement, the Fund receives income for lending its securities
either in the form of fees or by earning interest on invested cash collateral,
net of negotiated rebates paid to borrowers and fees paid to the lending agent
for services provided and any other securities lending expenses. Income of
$98,787 earned from securities lending from Dec. 1, 2008 through Jan. 31, 2009
is included in the Statement of Operations. The Fund also continues to earn
interest and dividends on the securities loaned.

Risks of delay in recovery of securities or even loss of rights in the
securities may occur should the borrower of the securities fail financially.
Risks may also arise to the extent that the value of the securities loaned
increases above the value of the collateral received. JPMorgan will indemnify
the Fund from losses resulting from a borrower's failure to return a loaned
security when due. Such indemnification does not extend to losses associated
with declines in the value of cash collateral investments. Loans are subject to
termination by the Funds or the borrower at any time, and are, therefore, not
considered to be illiquid investments.

Prior to Dec. 1, 2008, RiverSource Investments, LLC served as securities lending
agent for the Fund under the Securities Lending Agency Agreement pursuant to
which the Fund agreed to reimburse RiverSource Investments, LLC for expenses
incurred by it in connection with the lending program. Expenses paid to
RiverSource Investments, LLC as securities lending agent were $8,577 through
Nov. 30, 2008 and are included in other expenses on the Statement of Operations.
Cash collateral received on loaned securities had been invested in an affiliated
money market fund. Income of $81,290 earned from securities lending from Aug. 1,
2008 through Nov. 30, 2008 is included in the Statement of Operations.

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. The cost of the
Fund's purchases and proceeds from sales of shares of the RiverSource Short-Term
Cash fund aggregated $869,988,866 and $928,435,784, respectively, for the six

8. BANK BORROWINGS

The Fund has entered into a revolving credit facility with a syndicate of banks
led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund
may borrow for the temporary funding of shareholder redemptions or for other
temporary or emergency purposes. The credit facility became effective on Oct.
16, 2008, replacing a prior credit facility. The credit facility agreement,
which is a collective agreement between the Fund and certain other RiverSource
funds, severally and not jointly, permits collective borrowings up to $475
million. The borrowers shall have the right, upon written notice to the
Administrative Agent to request an increase of up to $175 million in the
aggregate amount of the credit facility from new or existing lenders, provided
that the aggregate amount of the credit facility shall at no time exceed $650
million. Participation in such increase by any existing lender shall be at such
lender's sole discretion. Interest is charged to each Fund based on its
borrowings at a rate equal to the federal funds rate plus 0.75%. Each borrowing
under the credit facility matures no later than 60 days after the date of
borrowing. 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, in addition to an upfront fee equal to its pro
rata share of 0.02% of the amount of the credit facility. The Fund had no
borrowings during the six months ended Jan. 31, 2009.

Under the prior credit facility which was effective until Oct. 15, 2008, the
Fund had entered into a revolving credit facility with a syndicate of banks
headed by JPMorgan Chase Bank, N.A., whereby the Fund was permitted to borrow
for the temporary funding of shareholder redemptions or for other temporary or
emergency purposes. The credit facility agreement, which was a collective
agreement between the Fund and certain other RiverSource funds, severally and
not jointly, permitted collective borrowings up to $500 million. Interest was
charged to each Fund based on its borrowings at a rate equal to the federal
funds rate plus 0.30%. Each borrowing under the credit facility matured no later
than 60 days after the date of borrowing. The Fund also paid a commitment fee
equal to its pro rata share of the amount of the credit facility at a rate of
0.06% per annum.

For federal income tax purposes, the Fund had a capital loss carry-over of
$91,172,850 at July 31, 2008, that if not offset by capital gains will expire as
follows:

<Table>
<Caption>
    2009           2010          2011
                        
$60,717,128    $20,982,455    $9,473,267
</Table>


Because the measurement periods for a regulated investment company's income are
different for excise tax purposes versus income tax purposes, special rules are
in place to protect the amount of earnings and profits needed to support excise
tax distributions. As a result, the Fund is permitted to treat net capital
losses realized between Nov. 1, 2007 and its fiscal year end ("post-October
loss") as occurring on the first day of the following tax year. At July 31,
2008, the Fund had a post-October loss of $143,836,621 that is treated for
income tax purposes as occurring on Aug. 1, 2008.

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.

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 defendants' motion to dismiss the
complaint, the Court dismissed one of plaintiffs' four claims and granted
plaintiffs limited discovery. Defendants moved for summary judgment in April
2007. Summary judgment was granted in the defendants' favor on July 9, 2007. The
plaintiffs filed a notice of appeal with the Eighth Circuit Court of Appeals on
August 8, 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)), entered into settlement agreements with the Securities
and Exchange Commission (SEC) and Minnesota Department of Commerce (MDOC)
related to market timing activities. As a result, 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. AEFC agreed to pay disgorgement of $10 million
and civil money penalties of $7 million. 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. 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.

On November 7, 2008, RiverSource Investments, LLC, a subsidiary of Ameriprise
Financial, Inc., acquired J. & W. Seligman & Co., Inc. (Seligman). In late 2003,
Seligman conducted an extensive internal review concerning mutual fund trading
practices. Seligman's review, which covered the period 2001-2003, noted one
arrangement that permitted frequent trading in certain open-end registered
investment companies managed by Seligman (the Seligman Funds);

- --------------------------------------------------------------------------------
                 RIVERSOURCE LARGE CAP EQUITY FUND -- 2009 SEMIANNUAL REPORT  53



NOTES TO FINANCIAL STATEMENTS (continued) --------------------------------------



this arrangement was in the process of being closed down by Seligman before
September 2003. Seligman identified three other arrangements that permitted
frequent trading, all of which had been terminated by September 2002. In January
2004, Seligman, on a voluntary basis, publicly disclosed these four arrangements
to its clients and to shareholders of the Seligman Funds. Seligman also provided
information concerning mutual fund trading practices to the SEC and the Office
of the Attorney General of the State of New York (NYAG). In September 2005, the
New York staff of the SEC indicated that it was considering recommending to the
Commissioners of the SEC the instituting of a formal action against Seligman and
the distributor of the Seligman Funds, Seligman Advisors, Inc. (which is now
know as RiverSource Fund Distributors, Inc.), relating to frequent trading in
the Seligman Funds. Seligman responded to the staff in October 2005 that it
believed that any action would be both inappropriate and unnecessary, especially
in light of the fact that Seligman had previously resolved the underlying issue
with the Independent Directors of the Seligman Funds and made recompense to the
affected Seligman Funds.

In September 2006, the NYAG commenced a civil action in New York State Supreme
Court against Seligman, Seligman Advisors, Inc., Seligman Data Corp. and Brian
T. Zino (collectively, the Seligman Parties), alleging, in substance, that the
Seligman Parties permitted various persons to engage in frequent trading and, as
a result, the prospectus disclosure used by the registered investment companies
then managed by Seligman is and has been misleading. The NYAG included other
related claims and also claimed that the fees charged by Seligman to the
Seligman Funds were excessive. On March 13, 2009, without admitting or denying
any violations of law or wrongdoing, the Seligman Parties entered into a
stipulation of settlement with the NYAG and settled the claims made by the NYAG.
Under the terms of the settlement, Seligman will pay $11.3 million to four
Seligman Funds. This settlement resolved all outstanding matters between the
Seligman Parties and the NYAG. In addition to the foregoing matter, the New York
staff of the SEC indicated in September 2005 that it was considering
recommending to the Commissioners of the SEC the instituting of a formal action
against Seligman and Seligman Advisors, Inc. relating to frequent trading in the
Seligman Funds. Seligman responded to the staff in October 2005 that it believed
that any action would be both inappropriate and unnecessary, especially in light
of the fact that Seligman had previously resolved the underlying issue with the
Independent Directors of the Seligman Funds and made recompense to the affected
Seligman Funds. There have been no further developments with the SEC on this
matter.

Ameriprise Financial and certain of its affiliates have historically been
involved in a number of legal, arbitration and regulatory proceedings, including
routine

- --------------------------------------------------------------------------------
54  RIVERSOURCE LARGE CAP EQUITY FUND -- 2009 SEMIANNUAL REPORT



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




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.
