 6 RIVERSOURCE DISCIPLINED EQUITY FUND -- 2008 SEMIANNUAL REPORT


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, 2008.

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

A: RiverSource Disciplined Equity Fund's Class A shares (excluding sales charge)
   declined 4.72% for the six months ended Jan. 31, 2008. The Fund
   underperformed the unmanaged Standard & Poor's 500 Index (S&P 500 Index),
   which fell 4.32%, as well as the Lipper Large-Cap Core Funds Index,
   representing the Fund's peer group, which declined 3.76%, for the same
   period.

   DURING THE SIX-MONTH PERIOD, THE QUALITY AND MOMENTUM MODELS OUTPERFORMED
   THE S&P 500 INDEX, BUT NOT ENOUGH TO OFFSET THE UNDERPERFORMANCE OF THE
   VALUE MODEL.


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

A: The Fund's performance resulted from the three quantitative investment
   models - momentum, value and quality - we employ in selecting stocks for the
   Fund's portfolio. During the six-month period, the quality and momentum
   models outperformed the S&P 500 Index, but not enough to offset the
   underperformance of the value model. The quality model was intended to serve,
   in part, as a defensive measure during equity market corrections when
   investor risk aversion increases, and it indeed took the lead throughout
   these challenging months. The value and quality models performed strongly
   when beaten-up financials and homebuilders rallied somewhat in January 2008,
   while the momentum model lagged. All of this supports our research indicating
   that the style diversification provided by the three quantitative models is a
   significant investment advantage over the long term, even though the Fund may
   experience underperformance in the short term.

   We do not make sector or industry bets based on our outlook for the economy
   or the equity markets. During the period, the Fund's quantitative models led
   to a bias toward large-cap and quality stocks, both of which boosted results,
   as these equity sectors performed comparatively well. At the same time,
   however, the Fund's models positioned the portfolio toward the cheapest
   price/earnings stocks, which detracted.

                RIVERSOURCE DISCIPLINED EQUITY FUND -- 2008 SEMIANNUAL REPORT  7

QUESTIONS & ANSWERS

   Overall, sector allocation contributed modestly to the Fund's performance,
   with a sizable weighting in energy and smaller positions in financials and
   information technology particularly helpful. Partially offsetting these
   positives were a moderate allocation to the strongly performing consumer
   staples sector and a significant exposure to the weaker consumer
   discretionary sector.

   Stock selection as a whole detracted slightly from Fund results, even though
   it was effective in nearly all of the sectors in which the Fund invests, and
   was especially strong in the information technology and consumer
   discretionary sectors. Such positives were not enough to offset the effect of
   weak stock selection in energy and financials.

   Among individual holdings, information technology company Apple, selected by
   the momentum model, contributed most to the Fund's return. Other strong,
   positive contributors included chemicals firm Monsanto, selected by the
   momentum model; fast-food restaurant giant McDonald's, favored by the
   momentum model; machinery leader Deere & Co, chosen by the momentum model;
   health care services company Express Scripts, another momentum model pick;
   and pharmaceutical company Johnson & Johnson, selected by the quality model.

   Stocks that detracted from the Fund's return included four financials
   companies, each selected by the value model, namely Fannie Mae, Citigroup,
   Freddie Mac and Washington Mutual. Other poor performers during the period
   were energy equipment firm Schlumberger, a momentum model pick, and metals
   and mining company Freeport-McMoRan Copper & Gold, selected by both the value
   and momentum models.

   At the end of January, the Fund's largest individual stock holdings were
   pharmaceutical giant Pfizer, a value and quality model choice; energy
   companies Chevron and Exxon Mobil, the former selected by all three models
   and the latter a quality model pick; information technology company Apple,
   selected by the momentum model; pharmaceutical company Johnson & Johnson, a
   quality model pick; and financial company Citigroup, selected by the value
   model.

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

A: As a result of quantitative models-driven stock selection during the period,
   the Fund's sector allocations changed somewhat. For example, the Fund's

QUESTIONS & ANSWERS

   exposure to telecommunication services and utilities decreased relative to
   the S&P 500 Index. The Fund's positions in health care, materials and
   financials increased. Our risk models limit the size of individual holdings,
   as well as sector and industry allocations relative to the S&P 500 Index. As
   an example, the Fund'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 measures that impose constraints on market
   capitalization, price, quality, turnover, transaction costs and other
   variables.

   WE INTEND TO CONTINUE SEEKING OPTIMAL RETURNS FOR THE FUND THROUGH THE
   STYLE DIVERSIFICATION OFFERED BY OUR THREE QUANTITATIVE INVESTMENT MODELS.


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

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

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, 2008.

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.

NOTES TO FINANCIAL STATEMENTS

(Unaudited as to Jan. 31, 2008)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

RiverSource Disciplined 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 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, Class I, Class R2, Class R3, Class
R4, Class R5 and Class W 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.

- -  Class W shares are sold without a front-end sales charge or CDSC and are
   offered through qualifying discretionary accounts.

At Jan. 31, 2008, RiverSource Investments, LLC (the Investment Manager) and the
affiliated funds-of-funds owned 100% of Class I shares and the Investment
Manager owned 100% of Class R2, Class R3 and Class R5 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.

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

 24 RIVERSOURCE DISCIPLINED EQUITY FUND -- 2008 SEMIANNUAL REPORT


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.
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 Exchange.

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.
Cash collateral may be collected by the Fund to secure certain over-the-counter
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

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

               RIVERSOURCE DISCIPLINED EQUITY FUND -- 2008 SEMIANNUAL REPORT  25


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. During
the six months ended Jan. 31, 2008, 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 are valued daily based upon the last sale price at the close of 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.

The Fund may enter into forward foreign currency 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

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

 26 RIVERSOURCE DISCIPLINED EQUITY FUND -- 2008 SEMIANNUAL REPORT


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. At Jan. 31, 2008, the Fund had no outstanding forward
foreign currency 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.

The Fund has adopted Financial Accounting Standards Board (FASB) Interpretation
48 (FIN 48), "Accounting for Uncertainty in Income Taxes," which is effective
for fiscal periods beginning after Dec. 15, 2006. 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. 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 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 PRONOUNCEMENT

On Sept. 20, 2006, the 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 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. The application of SFAS 157
will be effective for the Fund's fiscal year beginning Aug. 1, 2008. The
adoption of SFAS 157 is not anticipated to have a material impact on the Fund's
financial statements.

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, 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
performance of one Class A share of the Fund and the change in 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 fee by $254,064 for the six months ended Jan. 31, 2008. The
management fee for the six months ended Jan. 31, 2008 was 0.56% of the Fund's
average daily net assets, including an adjustment under the terms of the
performance incentive adjustment.

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, 2008 was 0.05%
of the Fund's average daily net assets.

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

 28 RIVERSOURCE DISCIPLINED EQUITY FUND -- 2008 SEMIANNUAL REPORT


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, 2008, other expenses paid to this company were $6,879.

Compensation of Board members includes, for a former Board Chair, compensation
as well as retirement benefits. Certain other aspects of a 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.

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:

- -  Class A $19.50

- -  Class B $20.50

- -  Class C $20.00

The Fund 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 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.

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.

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.

The Fund has an agreement with RiverSource Distributors, Inc. (the Distributor)
for distribution and shareholder services. Prior to Oct. 1, 2007, Ameriprise
Financial Services, Inc. also served as a principal underwriter and distributor
to the Fund. 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

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

               RIVERSOURCE DISCIPLINED EQUITY FUND -- 2008 SEMIANNUAL REPORT  29


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.

Sales charges received by the Distributor for distributing Fund shares were
$204,511 for Class A, $15,452 for Class B and $175 for Class C for the six
months ended Jan. 31, 2008.

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, 2008, the Investment Manager and its
affiliates waived/reimbursed certain fees and expenses such that net expenses
(excluding fees and expenses of acquired funds) were 1.18% for Class R2, 0.91%
for Class R3 and 0.86% for Class R4. Of these waived/reimbursed fees and
expenses, the transfer agency fee at the class level was $53,031 for Class R4
and the plan administration services fees at the class level were $6, $6 and
$953 for Class R2, Class R3 and Class R4, respectively. In addition, the
Investment Manager and its affiliates have contractually agreed to waive certain
fees and expenses until July 31, 2008, such that net expenses (excluding fees
and expenses of acquired funds), before giving effect to any performance
incentive adjustment, will not exceed 1.09% for Class A, 1.85% for Class B,
1.85% for Class C, 0.78% for Class I, 1.58% for Class R2, 1.33% for Class R3,
0.88% for Class R4, 0.83% for Class R5 and 1.23% for Class W of the Fund's
average daily net assets, unless sooner terminated at the discretion of the
Board.

During the six months ended Jan. 31, 2008, the Fund's custodian and transfer
agency fees were reduced by $59,689 as a result of earnings and bank fee credits
from overnight cash balances. The Fund pays custodian fees to Ameriprise Trust
Company, a subsidiary of Ameriprise Financial.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $1,565,251,143 and $801,902,036, respectively, for the
six months ended Jan. 31, 2008. Realized gains and losses are determined on an
identified cost basis.

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

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

               RIVERSOURCE DISCIPLINED EQUITY FUND -- 2008 SEMIANNUAL REPORT  31


guidelines adopted by and under the oversight of the Board. At Jan. 31, 2008,
securities valued at $31,717,843 were on loan to brokers. For collateral, the
Fund received $31,719,500 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 "Portfolio of Investments." Income from securities lending amounted to
$90,432 for the six months ended Jan. 31, 2008. Expenses paid to the Investment
Manager were $3,010 for the six months ended Jan. 31, 2008, which are included
in other expenses on the Statement of operations. 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. 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. The cost of the
Fund's purchases and proceeds from sales of shares of the RiverSource Short-Term
Cash Fund aggregated $832,368,029 and $707,236,435, respectively, for the six
months ended Jan. 31, 2008.

7. BANK BORROWINGS

The Fund has entered into a revolving credit facility 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 credit facility became effective on Oct. 18, 2007, 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 $500 million. Interest is
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 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. Under the prior credit facility, a Fund paid interest on its
outstanding 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. The Fund
had no borrowings during the six months ended Jan. 31, 2008.

8. 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

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

 32 RIVERSOURCE DISCIPLINED EQUITY FUND -- 2008 SEMIANNUAL REPORT


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.

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.

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

               RIVERSOURCE DISCIPLINED EQUITY FUND -- 2008 SEMIANNUAL REPORT  33


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.

QUESTIONS & ANSWERS WITH PORTFOLIO MANAGEMENT

Below, Portfolio Manager Nick Thakore discusses the Fund's positioning and
results for the semiannual period ended Jan. 31, 2008.

Q: How did RiverSource Growth Fund perform for the six months ended Jan. 31,
   2008?

A: RiverSource Growth Fund's Class A shares declined 6.43%, excluding sales
   charge, for the six months ended Jan. 31, 2008. The Fund underperformed its
   benchmark, the Russell 1000(R) Growth Index (Russell Index), which declined
   3.15%, and its peer group as represented by the Lipper Large-Cap Growth Funds
   Index, which declined 1.09% for the same period.

Q: What factors influenced performance during the period?

A: The market's preference for a narrow group of stocks that included both
   cyclical companies and very fast growing companies with strong fundamentals
   had a negative impact on the Fund's results. We generally avoided such stocks
   because we questioned the companies' ability to sustain high growth rates or
   because we considered them overvalued. Our concerns were validated in January
   2008 as many of these stocks fell sharply.

   Stock selection in telecommunication services, information technology,
   materials and consumer staples had a positive impact on the Fund's
   performance relative to the Russell Index. Although the Fund's
   telecommunications holdings outperformed, the sector was weak overall and
   having a larger telecommunications weighting than the Russell Index was
   detrimental. Stock selection in consumer discretionary, health care,
   industrials and financials also detracted from performance.

   STOCK SELECTION IN CONSUMER DISCRETIONARY, HEALTH CARE, INDUSTRIALS AND
   FINANCIALS ALSO DETRACTED FROM PERFORMANCE.


   Stocks that did well during the period included Vodafone Group and Deutsche
   Telekom, Lihir Gold, QUALCOMM and Nokia. Vodafone Group and Deutsche Telekom
   are two European telecommunications firms that have experienced a turnaround
   in fundamentals. Lihir Gold benefited as gold stocks performed strongly. The
   company is one of the few gold stocks where production is rising and costs
   are declining. QUALCOMM has had strong fundamentals, but was hampered by
   outstanding legal issues, which may be resolved in 2008. We think the stock
   price assumes a negative outcome and if the resolution is

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

 8 RIVERSOURCE GROWTH FUND -- 2008 SEMIANNUAL REPORT

QUESTIONS & ANSWERS

   neutral or favorable, the stock could benefit. Nokia has continued to
   dominate the cell phone handset business, improving margins and capitalizing
   on competitor Motorola's weakness.

   Virgin Media, Harman International Inds and Hertz Global Holdings, three
   consumer discretionary companies, detracted from performance as did
   semiconductor firm Spansion. After receiving an attractive acquisition bid,
   Virgin Media was conducting an auction at the start of the semiannual period.
   Multiple suitors showed interest, but difficulties in the high yield bond
   market halted the auction and the stock price fell below even the initial bid
   amount. We continue to see hidden value in Virgin Media, which management may
   be able to realize on its own. Audio equipment maker Harman International
   Inds was in the midst of a leveraged buyout when the two private equity firms
   involved pulled out of the deal. We owned rental car company Hertz Global
   Holdings as a restructuring opportunity where significant cost cutting was
   likely to produce solid growth. The stock declined on fears that earnings
   estimates would fall due to economic slowing. We believe Hertz Global
   Holdings has a better business model than it is given credit for and that
   cost cutting efforts might offset economy-related slowing. If not, we think
   the stock's price already reflects the possibility of slower earnings.
   Spansion suffered as prices in the memory chip market declined faster than
   expected.

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

A: During the period, we increased the Fund's technology weighting primarily
   due to bottom-up stock purchases in the sector. For example, we increased
   holdings of QUALCOMM and Nokia.

   We also added to the Fund's consumer discretionary weighting. The Fund hasn't
   generally emphasized retail, but as these stocks sold off aggressively,
   valuations became more appealing and we began to identify selective
   opportunities. We added to personal care retailer Avon Products because we
   believe its management team is restructuring properly, investing in the
   business to drive top line growth while also cutting costs.

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

                            RIVERSOURCE GROWTH FUND -- 2008 SEMIANNUAL REPORT  9

QUESTIONS & ANSWERS

   WE LOWERED THE FUND'S ENERGY WEIGHTING BECAUSE WE BELIEVE THIS SECTOR'S
   NEAR-TERM FUNDAMENTALS ARE NOT AS FAVORABLE AS ITS LONG-TERM FUNDAMENTALS.


   We reduced exposure to energy, health care and telecommunication services. We
   lowered the Fund's energy weighting because we believe this sector's near-
   term fundamentals are not as favorable as its long-term fundamentals. In the
   health care sector, we reduced holdings of AstraZeneca and Merck & Co, while
   adding to Bristol-Myers Squibb. We considered AstraZeneca an inexpensive
   stock with reasonable growth prospects, but eliminated the position amid
   concerns that near-term fundamentals were weakening. After Merck & Co
   performed well, we trimmed the position on valuation grounds and concern that
   the company's joint venture with Schering-Plough would negatively affect
   fundamentals. We believe that for the next few years Bristol-Myers Squibb is
   likely to have a good earnings growth rate that is not yet reflected in the
   stock's valuation.

   We still see growth opportunities in the telecommunication services sector
   and maintained an overweight relative to the Russell Index. However, as
   individual holdings within the sector performed well, we trimmed some
   positions such as Vodafone Group. Within the sector, we added to AT&T, a
   stock that had languished for six months while the company's growth
   continued. We also reduced holdings of General Electric because we think its
   financial services business makes it vulnerable to consumer finance weakness.

Q: How are you positioning the Fund going forward?

A: Looking ahead, we anticipate a continuation of trends from 2007, including
   continued deceleration in earnings growth. Our emphasis remains on the very
   largest stocks, which began to deliver results in 2007. We think this trend
   will endure over an extended period. These companies are growing earnings
   faster than the rest of the market now and their liquidity is helpful given
   increased volatility.

 10 RIVERSOURCE GROWTH FUND -- 2008 SEMIANNUAL REPORT

QUESTIONS & ANSWERS

   WE BELIEVE OUR CAREFUL BALANCING OF GROWTH POTENTIAL WITH SOUND VALUATION
   LEAVES THE FUND WELL-POSITIONED FOR THE CURRENT ENVIRONMENT.


   We continue to seek exposure to the faster growing stocks in our universe,
   but remain disciplined in our approach. Some great growth stories are just
   too expensive, in our view. We believe this approach helps shield the Fund
   should these faster growers encounter problems, and will be beneficial in the
   more balanced equity environment we anticipate for 2008.

   Though the Fund's strategy was hampered over the past six months by the
   market's embrace of cyclical stocks and its indifference to high stock
   valuations, our strategy has worked over time. We believe our careful
   balancing of growth potential with sound valuation leaves the Fund
   well-positioned for the current environment.

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, 2008.

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.

NOTES TO FINANCIAL STATEMENTS

(Unaudited as to Jan. 31, 2008)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

RiverSource Growth 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 common stocks of U.S. and foreign
companies that appear to offer growth opportunities.

The Fund offers Class A, Class B, Class C, Class I, Class R2, Class R3, Class
R4, Class R5 and Class W 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 only offered to qualifying
   institutional investors.

- -  Class W shares are sold without a front-end sales charge or CDSC and are
   offered through qualifying discretionary accounts.

At Jan. 31, 2008, RiverSource Investments, LLC (the Investment Manager) and the
affiliated funds-of-funds owned 100% of Class I shares and the Investment
Manager owned 100% of Class R2, Class R3, Class R5 and Class W 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.

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.
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 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.

ILLIQUID SECURITIES

At Jan. 31, 2008, 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, 2008 was
$31,537,938 representing 1.2% of net assets. These securities may be valued 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 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. 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.

Futures are valued daily based upon the last sale price at the close of 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. At Jan. 31, 2008, the Fund
had no outstanding futures contracts.

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

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

                           RIVERSOURCE GROWTH FUND -- 2008 SEMIANNUAL REPORT  27


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, 2008, foreign currency holdings consisted of
British pounds.

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.

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 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.

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.

The Fund has adopted Financial Accounting Standards Board (FASB) Interpretation
48 (FIN 48), "Accounting for Uncertainty in Income Taxes," which is effective
for fiscal periods beginning after Dec. 15, 2006. 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. 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 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 PRONOUNCEMENT

On Sept. 20, 2006, the 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 hierarchy for measuring fair
value, and requires additional disclosures about the inputs used to develop the

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

                           RIVERSOURCE GROWTH FUND -- 2008 SEMIANNUAL REPORT  29


measurements of fair value and the effect of certain measurements reported in
the Statement of operations for a fiscal period. The application of SFAS 157
will be effective for the Fund's fiscal year beginning Aug. 1, 2008. The
adoption of SFAS 157 is not anticipated to have a material impact on the Fund's
financial statements.

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. 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, 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
performance of one Class A share of the Fund and the change in 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
decreased the fee by $1,840,359 for the six months ended Jan. 31, 2008. The
management fee for the six months ended Jan. 31, 2008 was 0.46% of the Fund's
average daily net assets, including an adjustment under the terms of the
performance incentive agreement.

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, 2008 was 0.05%
of the Fund's average daily net assets.

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, 2008, other expenses paid to this company were $9,664.

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

 30 RIVERSOURCE GROWTH FUND -- 2008 SEMIANNUAL REPORT


Compensation of Board members includes, for a former Board Chair, compensation
as well as retirement benefits. Certain other aspects of a 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.

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:

- -  Class A $19.50

- -  Class B $20.50

- -  Class C $20.00

The Fund pays the Transfer Agent an annual asset-based fee at a rate of 0.05% of
the Fund's average daily net asset attributable to Class R2, Class R3, Class R4
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.

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.

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.

The Fund has an agreement with RiverSource Distributors, Inc. (the Distributor)
for distribution and shareholder services. Prior to Oct. 1, 2007, Ameriprise
Financial Services, Inc. also served as a principal underwriter and distributor
to the Fund. 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.

Sales charges received by the Distributor for distributing Fund shares were
$959,246 for Class A, $133,794 for Class B and $766 for Class C for the six
months ended Jan. 31, 2008.

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

                           RIVERSOURCE GROWTH FUND -- 2008 SEMIANNUAL REPORT  31


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, 2008, the Investment Manager and its
affiliates waived/reimbursed certain fees and expenses such that net expenses
(excluding fees and expenses of acquired funds) were 1.10% for Class R2, 0.86%
for Class R3 and 0.67% for Class R4. Of these waived/reimbursed fees and
expenses, the plan administration services fees at the class level were $7, $7
and $121,769 for Class R2, Class R3 and Class R4, respectively. In addition, the
Investment Manager and its affiliates have contractually agreed to waive certain
fees and expenses until July 31, 2008, such that net expenses (excluding fees
and expenses of acquired funds), before giving effect to any performance
incentive adjustment, will not exceed 0.97% of the Fund's average daily net
assets for Class R4, unless sooner terminated at the discretion of the Board.

During the six months ended Jan. 31, 2008, the Fund's transfer agency fees were
reduced by $87,510 as a result of bank fee credits from overnight cash balances.

The Fund pays custodian fees to Ameriprise Trust Company, a subsidiary of
Ameriprise Financial.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $1,650,320,449 and $2,004,469,643, respectively, for the
six months ended Jan. 31, 2008. Realized gains and losses are determined on an
identified cost basis.

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

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

                           RIVERSOURCE GROWTH FUND -- 2008 SEMIANNUAL REPORT  33


guidelines adopted by and under the oversight of the Board. At Jan. 31, 2008,
securities valued at $46,150,808 were on loan to brokers. For collateral, the
Fund received $50,420,900 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 "Portfolio of Investments." Income from securities lending amounted to
$462,224 for the six months ended Jan. 31, 2008. Expenses paid to the Investment
Manager were $6,604 for the six months ended Jan. 31, 2008, which are included
in other expenses on the Statement of operations. 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. 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. The cost of
purchases and proceeds from sales of shares of RiverSource Short-Term Cash Fund
aggregated $764,797,671 and $733,155,132, respectively, for the six months ended
Jan. 31, 2008.

8. BANK BORROWINGS

The Fund has entered into a revolving credit facility 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 credit facility became effective on Oct. 18, 2007, 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 $500 million. Interest is
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 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. Under
the prior credit facility, a Fund paid interest on its outstanding 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. The Fund had no borrowings during
the six months ended Jan. 31, 2008.

9. CAPITAL LOSS CARRY-OVER

For federal income tax purposes, the Fund had a capital loss carry-over of
$284,278,656 at July 31, 2007, that if not offset by capital gains will expire
in 2011. It is unlikely the Board will authorize a distribution of any 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

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.

 6 RIVERSOURCE LARGE CAP EQUITY FUND -- 2008 SEMIANNUAL REPORT


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, 2008.

Q: How did RiverSource Large Cap Equity Fund perform for the six months ended
   Jan. 31, 2008?

A: RiverSource Large Cap Equity Fund's Class A shares declined 5.85%,
   excluding sales charge, for the semiannual period ended Jan. 31, 2008. The
   Fund underperformed its benchmarks, the Russell 1000(R) Index (Russell Index)
   and the Standard & Poor's 500 Index (S&P 500 Index), which declined 4.27% and
   4.32%, respectively. The Fund's peer group, the Lipper Large-Cap Core Funds
   Index, declined 3.76% during the same time frame.

Q: What factors most significantly affected performance during the six months?

A: In a period of decelerating economic growth and a difficult lending
   environment, both stock selection and sector weightings had a negative impact
   on the Fund's performance relative to the Russell Index. While stock
   selection in the telecommunication services, consumer staples and information
   technology sectors was favorable, this was offset by underperformance of the
   Fund's holdings in the consumer discretionary, health care and financials
   sectors.

   Looking at sector weightings, the Fund benefited from lower exposure to
   financials and greater exposure to health care, both versus the Russell
   Index. On the other hand, a larger weighting in telecommunication services
   and a smaller energy sector weighting versus the Russell Index were both
   detrimental.

   Although our telecommunication services sector weighting detracted, the
   Fund's focus on European telecommunication services stocks was advantageous.
   Stocks such as Vodafone Group and Deutsche Telekom benefited from a
   turnaround in fundamentals. U.S. telecommunication services equipment stock
   QUALCOMM also did well as the company experienced good fundamental trends and
   made some progress on outstanding legal issues. We think QUALCOMM's stock
   price reflects a negative outcome for these legal issues, which may be
   resolved in 2008. If the resolution is neutral or favorable, the stock could
   benefit.

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

                  RIVERSOURCE LARGE CAP EQUITY FUND -- 2008 SEMIANNUAL REPORT  7

QUESTIONS & ANSWERS

   ALTHOUGH OUR TELECOMMUNICATION SERVICES SECTOR WEIGHTING DETRACTED, THE
   FUND'S FOCUS ON EUROPEAN TELECOMMUNICATION SERVICES STOCKS WAS
   ADVANTAGEOUS.

   Other positions in the portfolio did well. Lihir Gold benefited as gold
   stocks performed strongly. This company appears well-positioned for
   potentially explosive growth because it is one of the few gold stocks where
   production is rising and costs are declining. Having a smaller position in
   energy services stock Schlumberger relative to the Russell Index was also
   advantageous. The North American segment of the energy services group
   decelerated sharply, catching Schlumberger somewhat off guard.

   Two individual detractors, Virgin Media and Harmon International Inds, were
   almost solely responsible for the Fund's underperformance in the consumer
   discretionary sector. Virgin Media was affected by general concerns about the
   cable industry and negative response to an aggressive customer acquisition
   strategy that reduced near-term cash flow. Additionally, Virgin Media
   received an attractive acquisition offer in July that was later scuttled due
   to weakening in high-yield credit markets. We continue to see hidden value in
   this company and believe management may be able to realize on its own even
   without a buyer. Harman International Inds is an audio equipment maker that
   was in the midst of a leveraged buyout when the two private equity firms
   involved pulled out of the deal.

   Additional detractors included Countrywide Financial, Spansion and Sprint
   Nextel. Mortgage lender Countrywide Financial declined in the face of a
   challenging lending environment. We thought the company had navigated the
   troubled waters, but liquidity issues subsequently surfaced. Toward the end
   of the period, the company agreed to an acquisition by Bank of America, which
   should close later this year. The stock's performance improved slightly
   following the news. Spansion, a semiconductor memory chip company, suffered
   as prices in the memory chip market eroded faster than expected. Sprint
   Nextel continues to wrestle with effective company-level execution, mostly on
   the wireless side of its business. The telecommunication services company has
   experienced higher customer turnover than many of its

QUESTIONS & ANSWERS

   competitors. Although there have been changes to senior management, Sprint
   Nextel has yet to show any stabilization in its fundamentals.

Q: What changes did you make to the portfolio?

A: We decreased the Fund's health care weighting relative to the Russell Index.
   This resulted from reduced exposure to biotechnology stocks due to both
   valuation concerns and fundamental disappointments. Execution in the
   biotechnology industry was not especially strong during this period. We also
   decreased exposure to some larger cap pharmaceutical stocks that had gotten
   more expensive and might be negatively affected by a change in presidential
   administrations.

   THE FUND'S WEIGHTING IN MATERIALS STOCKS HAS ALSO DECREASED, A FUNCTION OF
   A REDUCTION IN THE PORTFOLIO'S EXPOSURE TO GOLD STOCKS.

   We increased exposure to the consumer staples sector relative to the Russell
   Index. Given that consumer staples stocks are a bit more expensive, we have
   not been interested in the more traditional staples segments such as food
   stocks and consumer goods companies. Rather, our interest has been very
   selective, focusing on stocks with a consumer cyclical dimension. The Fund's
   weighting in materials stocks has also decreased, a function of a reduction
   in the portfolio's exposure to gold stocks.

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

A: We manage the portfolio in three segments -- growth-oriented, value-oriented
   and analyst-driven -- and several prominent themes cross the three segments.
   There is a preference for high quality stocks over lower quality stocks.
   Though high quality stocks lagged in 2007, we think investors are likely to
   favor them in a period of slower economic activity, which seems probable for
   2008.

   IN A DIFFICULT ECONOMIC ENVIRONMENT WE WANT STOCK OF COMPANIES THAT HAVE
   GREATER CONTROL OVER THEIR EARNINGS GROWTH RATHER THAN THOSE THAT DEPEND
   ON THE ECONOMIC CYCLE.

   The portfolio also has more exposure to stocks with stable growth patterns.
   In a difficult economic environment we want stock of companies that have
   greater control over their earnings growth rather than those that depend on
   the

QUESTIONS & ANSWERS

   economic cycle. We also continue to emphasize the larger stocks within our
   universe. Large-cap stocks remain reasonably valued versus small- and mid-cap
   stocks and they also have the potential to benefit from broader product
   lines, greater international exposure and more extensive resources.

   Our strategy has always been very sensitive to valuations and in the current
   environment we have been finding more attractive valuation opportunities.
   This allows us to add better quality companies to the portfolio at attractive
   valuations or to improve the portfolio's overall valuation.

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, 2008.

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.

                  RIVERSOURCE LARGE CAP EQUITY FUND - 2008 SEMIANNUAL REPORT  23

(a)  Securities are valued by using 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, 2008, the
     value of foreign securities represented 8.0% of net assets.

(d)  Represents a security sold under Rule 144A, which is exempt from
     registration under the Securities Act of 1933, as amended. This security
     has been determined to be liquid under guidelines established by the Fund's
     Board of Directors. These securities may be resold in transactions exempt
     from registration, normally to qualified institutional buyers. At Jan. 31,
     2008, the value of these securities amounted to $28,710,656 or 0.5% of net
     assets.

(e)  Shareholders of tracking stocks have a financial interest only in a unit or
     division of the company. Unlike the common stock of the company itself, a

     company's liquidation, tracking stock shareholders typically do not have a
     legal claim on the company's assets.

NOTES TO FINANCIAL STATEMENTS

(Unaudited as to Jan. 31, 2008)

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, 2008, RiverSource Investments, LLC (the Investment Manager) and the
affiliated funds-of-funds owned 100% of Class I shares and the Investment
Manager owned 100% of Class R2, Class R3 and Class R5 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.

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-

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

 32 RIVERSOURCE LARGE CAP EQUITY FUND -- 2008 SEMIANNUAL REPORT


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. 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 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.

ILLIQUID SECURITIES

At Jan. 31, 2008, investments in securities included issues that are illiquid
which the Fund limits to 15% of net assets, at market value, at the time of
purchase. The aggregate value of such securities at Jan. 31, 2008 was
$28,710,656 representing 0.55% of net assets. These securities may be valued 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.

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

                 RIVERSOURCE LARGE CAP EQUITY FUND -- 2008 SEMIANNUAL REPORT  33


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 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. 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.

Futures are valued daily based upon the last sale price at the close of 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

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

 34 RIVERSOURCE LARGE CAP EQUITY FUND -- 2008 SEMIANNUAL REPORT


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,
2008, foreign currency holdings consisted of European monetary units and Indian
rupees.

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 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 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.

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

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

                 RIVERSOURCE LARGE CAP EQUITY FUND -- 2008 SEMIANNUAL REPORT  35


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.

The Fund has adopted Financial Accounting Standards Board (FASB) Interpretation
48 (FIN 48), "Accounting for Uncertainty in Income Taxes," which is effective
for fiscal periods beginning after Dec. 15, 2006. 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. 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 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 PRONOUNCEMENT

On Sept. 20, 2006, the 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 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. The application of SFAS 157
will be effective for the Fund's fiscal year beginning Aug. 1, 2008. The
adoption of SFAS 157 is not anticipated to have a material impact on the Fund's
financial statements.

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, 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
performance of one Class A share of the Fund and the change in 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 fee by $1,044,917 for the six months ended Jan. 31, 2008. The
management fee for the six months ended Jan. 31, 2008 was 0.52% of the Fund's
average daily net assets, including an adjustment under the terms of the
performance incentive arrangement.

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, 2008 was 0.05%
of the Fund's average daily net assets.

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, 2008, other expenses paid to this company were $19,032.

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

                 RIVERSOURCE LARGE CAP EQUITY FUND -- 2008 SEMIANNUAL REPORT  37


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.

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:

- -  Class A $19.50

- -  Class B $20.50

- -  Class C $20.00

The Fund 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.

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.

The Fund has an agreement with RiverSource Distributors, Inc. (the Distributor)
for distribution and shareholder services. Prior to Oct. 1, 2007, Ameriprise
Financial Services, Inc. also served as a principal underwriter and distributor
to the Fund. 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.

Sales charges received by the Distributor for distributing Fund shares were
$1,370,536 for Class A, $398,649 for Class B and $1,673 for Class C for the six
months ended Jan. 31, 2008.

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

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

 38 RIVERSOURCE LARGE CAP EQUITY FUND -- 2008 SEMIANNUAL REPORT


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, 2008, the Investment Manager and its
affiliates waived/reimbursed certain fees and expenses such that net expenses
(excluding fees and expenses of acquired funds) were 1.01% for Class A, 1.77%
for Class B, 1.77% for Class C, 1.14% for Class R2, 0.89% for Class R3 and 0.86%
for Class R4. Of these waived/reimbursed fees and expenses, the transfer agency
fees at the class level were $949,592, $185,600, $5,933 and $60,275 for Class A,
Class B, Class C and Class R4, respectively, and the plan administration
services fees were $6, $6 and $6,061 for Class R2, Class R3 and Class R4,
respectively. In addition, the Investment Manager and its affiliates have
contractually agreed to waive certain fees and expenses such that net expenses
(excluding fees and expenses of acquired funds), before giving effect to any
performance incentive adjustment, will not exceed 1.05% for Class A, 1.81% for
Class B, 1.81% for Class C, 0.67% for Class I, 1.47% for Class R2, 1.22% for
Class R3, 0.90% for Class R4 and 0.72% for Class R5 of the Fund's average daily
net assets until July 31, 2008, unless sooner terminated at the discretion of
the Board.

During the six months ended Jan. 31, 2008, the Fund's custodian and transfer
agency fees were reduced by $290,150 as a result of earnings and bank fee
credits from overnight cash balances. The Fund pays custodian fees to Ameriprise
Trust Company, a subsidiary of Ameriprise Financial.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $1,897,572,491 and $2,642,491,177, respectively, for the
six months ended Jan. 31, 2008. Realized gains and losses are determined on an
identified cost basis.

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, 2008, securities valued at $80,633,997 were
on loan to brokers. For collateral, the Fund received $82,441,000 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 "Portfolio of Investments." Income
from securities lending amounted to $513,750 for the six months ended Jan. 31,
2008. Expenses paid to the Investment Manager were $15,734 for the six months
ended Jan. 31, 2008, which are included in other expenses on the Statement of
operations. 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. 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. The cost of the
Fund's purchases and proceeds from sales of shares of the RiverSource Short-Term
Cash fund aggregated $1,825,856,449 and $1,804,523,335, respectively, for the
six months ended Jan. 31, 2008.

8. BANK BORROWINGS

The Fund has entered into a revolving credit facility 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 credit facility became effective on Oct. 18, 2007, 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 $500 million. Interest is
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 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. Under the

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

                 RIVERSOURCE LARGE CAP EQUITY FUND -- 2008 SEMIANNUAL REPORT  41


prior credit facility, a Fund paid interest on its outstanding 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. The Fund had no borrowings during
the six months ended Jan. 31, 2008.

9. CAPITAL LOSS CARRY-OVER

For federal income tax purposes, the Fund had a capital loss carry-over of
$158,388,854 at July 31, 2007, that if not offset by capital gains will expire
as follows:

<Table>
<Caption>
   2008          2009          2010          2011
                                 
$51,243,861   $70,190,395   $24,231,893   $12,722,705
</Table>

RiverSource Large Cap Equity Fund acquired $33,183,702 of capital loss carry-
overs in connection with a merger on March 10, 2006, as well as capital loss
carry-overs acquired as a result of prior mergers. 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.

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

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

 42 RIVERSOURCE LARGE CAP EQUITY FUND -- 2008 SEMIANNUAL REPORT


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.

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.

QUESTIONS & ANSWERS WITH PORTFOLIO MANAGEMENT

Below, Portfolio Manager Bob Ewing discusses the Fund's results and positioning
for the semiannual period ended Jan. 31, 2008.

Q: How did RiverSource Large Cap Value Fund perform for the six months ended
   Jan. 31, 2008?

A: RiverSource Large Cap Value Fund's Class A shares declined 7.16%,
   excluding sales charge, for the semiannual period ended Jan. 31, 2008. The
   Fund's benchmark, the Russell 1000(R) Value Index (Russell Index), declined
   5.42% during the period. The Fund's peer group, the Lipper Large-Cap Value
   Funds Index, declined 5.53% during the same time frame.

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

A: The past six months were difficult for the U.S. stock markets, characterized
   by economic deceleration and a great deal of credit uncertainty precipitated
   by subprime mortgage lending difficulties. This combination proved especially
   damaging to the Fund's financial holdings. In response to the economic
   challenges, the Federal Reserve Board (the Fed) reduced the federal funds
   rate five times between September and January, reversing its previous
   monetary policy stance, which had been more focused on fighting inflation.

   THE MORTGAGE ISSUES OF 2007 CAME TO A HEAD DURING THE SEMIANNUAL PERIOD,
   AFFECTING A NUMBER OF INDIVIDUAL STOCKS IN THE PORTFOLIO.


   Both stock selection and sector weightings relative to the Russell Index
   hampered the Fund's results. While stock selection in the industrials,
   information technology and telecommunication services sectors were favorable,
   the Fund's holdings in the financials, energy and health care sectors
   underperformed. In terms of sector weightings, having less exposure to
   financials was advantageous, as was a larger health care weighting. However,
   an overweight in technology and an underweight in utilities was detrimental.

   The mortgage issues of 2007 came to a head during the semiannual period,
   affecting a number of individual stocks in the portfolio. On the positive
   side, the Fund benefited from having a smaller position versus the Russell
   Index in Washington Mutual, a large mortgage issuer. Conversely, the Fund's
   position in mortgage lender Countrywide Financial was the most significant
   individual
- --------------------------------------------------------------------------------

 6 RIVERSOURCE LARGE CAP VALUE FUND -- 2008 SEMIANNUAL REPORT

QUESTIONS & ANSWERS

   detractor from return. Toward the end of the six-month period, Countrywide
   agreed to be acquired by Bank of America, a deal expected to close later this
   year. The stock's performance improved slightly following the announcement.
   The Fund's holdings of government-sponsored Federal Home Loan Mortgage Corp.
   (Freddie Mac) were also caught up in the negative lending environment.
   Although Freddie Mac was not directly affected by mortgage problems,
   investors became concerned that weakness could eventually affect it.

   Additional contributors included AFLAC, Microsoft, KB Home and Lockheed
   Martin. Life and disability insurance company AFLAC benefited from improving
   fundamentals and a substantial Japanese presence that allowed the company to
   benefit from currency exchange rates as the U.S. dollar remained weak
   relative to the Japanese yen. Microsoft benefited as its Windows Vista
   operating system began to gain traction. Though homebuilders were weak during
   the six month period and, as a group, did not add value for the Fund, we
   bought KB Home after much of the decline in the homebuilding sector. We feel
   that investors have since begun to anticipate some stabilization in the
   homebuilding environment. Defense contractor Lockheed Martin benefited from
   its stable business and performed well during the period.

   Additional detractors versus the Russell Index included overweight positions
   in Spansion and Virgin Media and an underweight in Occidental Petroleum.
   Spansion, a semiconductor memory chip company, detracted as prices in the
   memory chip market eroded faster than expected. Virgin Media received an
   attractive acquisition offer in July and was in the midst of a strategic
   auction at the start of the semiannual period. However, weakness in the high
   yield bond market halted the process and the stock price fell below even the
   original bid amount. We continue to see hidden value in Virgin Media and
   think management may realize it without an acquisition. Having an underweight
   position in Occidental Petroleum detracted from performance as energy stocks
   generally benefited from high commodity prices throughout the period.
   However, we believed there were better opportunities elsewhere in the energy
   sector.

Q: What changes did you make to the Fund during this period?

A: We increased exposure to the consumer discretionary sector relative to the
   Russell Index. Stocks in this sector had become relatively inexpensive and
- --------------------------------------------------------------------------------

                   RIVERSOURCE LARGE CAP VALUE FUND -- 2008 SEMIANNUAL REPORT  7

QUESTIONS & ANSWERS

   initially drove this change. We also concluded that the Fed's efforts to
   fight economic deceleration by reducing short-term interest rates should
   benefit this sector, particularly selected homebuilders and retailers.

   WE ALSO INCREASED EXPOSURE TO THE TELECOMMUNICATION SERVICES INDUSTRY
   GROUP, THOUGH THIS IS NOT A THEMATIC CHANGE, BUT A BOTTOM-UP OPPORTUNITY.


   We decreased the Fund's utilities position relative to the Russell Index.
   This reflects our belief that if the Fed continues to stimulate the economy,
   certain types of cyclical companies may benefit more than companies with less
   cyclical businesses, such as utilities. We also increased exposure to the
   telecommunication services industry group, though this is not a thematic
   change, but a bottom-up opportunity. Several telecommunication services
   stocks, specifically telephone companies, had become inexpensive and
   subsequently quite attractive to us.

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

   In general, we agree with the broad consensus that the U.S. is in an economic
   deceleration. However, we think the Fed will take steps to aggressively
   combat this situation and nine months to a year from now we could be on
   better economic footing.

   Consequently, we are striving to hold stocks that we believe will be
   beneficiaries of economic stabilization.

   In such an environment, we believe the portfolio's three primary themes
   continue to present attractive opportunities. First, we still think large-cap
   stocks are more attractive than small- and mid-cap stocks. They have greater
   international exposure, while trading at about the same price-to-earnings
   multiple as small- and mid-cap stocks. Second, we also maintain the Fund's
   current preference for reasonably priced stocks with growth characteristics
   over those with value traits. Third, we think an emphasis on high quality
   stocks is likely to be advantageous going forward. These stocks are trading
   at the same valuations as low quality stocks and with economic expansion
   faltering, we think investors will begin to favor them.

 8 RIVERSOURCE LARGE CAP VALUE FUND -- 2008 SEMIANNUAL REPORT

QUESTIONS & ANSWERS

   WE HAVE IMPLEMENTED A NEW THEME IN THE PORTFOLIO, A FOCUS ON CONTRARIAN
   OPPORTUNITIES.


   We have implemented a new theme in the portfolio, a focus on contrarian
   opportunities. These are stocks whose valuations are so low that they are
   compelling to us even after taking into account the companies' troubled
   fundamental conditions. Examples include segments of the financial market
   such as mortgage companies and savings and loans, many of which are trading
   at highly discounted levels. In the consumer discretionary sector examples
   include homebuilders, which we believe are trading below liquidation values,
   and selected retailers. Traditionally, stocks purchased at valuations like
   these contribute to outperformance over time and we are carefully considering
   individual opportunities. Stocks that fit this theme also have the potential
   to benefit from the Fed's apparent willingness to lower interest rates to
   stimulate economic growth.

Any specific securities mentioned are for illustrative purposes only and are not

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, 2008.

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

your costs would have been higher.

 22 RIVERSOURCE LARGE CAP VALUE FUND -- 2008 SEMIANNUAL REPORT


NOTES TO FINANCIAL STATEMENTS

(Unaudited as to Jan. 31, 2008)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

RiverSource Large Cap Value 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.

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, 2008, RiverSource Investments, LLC (the Investment Manager) and the
affiliated funds-of-funds owned 100% of Class I shares and the Investment
Manager owned 100% of Class R2, Class R3 and Class R5 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.

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-

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

                  RIVERSOURCE LARGE CAP VALUE FUND -- 2008 SEMIANNUAL REPORT  23


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. 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 Exchange.

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, 2008, 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, 2008 was
$295,625 representing 0.41% of net assets. These securities may be valued 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

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

 24 RIVERSOURCE LARGE CAP VALUE FUND -- 2008 SEMIANNUAL REPORT


be collected by the Fund to secure certain over-the-counter 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. 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. During
the six months ended Jan. 31, 2008, 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 are valued daily based upon the last sale price at the close of 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. At Jan. 31, 2008, the Fund
had no outstanding futures contracts.

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

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

                  RIVERSOURCE LARGE CAP VALUE FUND -- 2008 SEMIANNUAL REPORT  25


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,
2008, foreign currency holdings were entirely comprised of Indian rupees.

The Fund may enter into forward foreign currency 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. At Jan. 31, 2008, the Fund had no outstanding
forward foreign currency 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.

The Fund has adopted Financial Accounting Standards Board (FASB) Interpretation
48 (FIN 48), "Accounting for Uncertainty in Income Taxes," which is effective
for fiscal periods beginning after Dec. 15, 2006. 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. 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.

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

 26 RIVERSOURCE LARGE CAP VALUE FUND -- 2008 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 PRONOUNCEMENT

On Sept. 20, 2006, the 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 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. The application of SFAS 157
will be effective for the Fund's fiscal year beginning Aug. 1, 2008. The
adoption of SFAS 157 is not anticipated to have a material impact on the Fund's
financial statements.

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, 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
performance of one Class A share of the Fund and the change in 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 $22,174 for the six months ended Jan. 31, 2008. The

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

                  RIVERSOURCE LARGE CAP VALUE FUND -- 2008 SEMIANNUAL REPORT  27


management fee for the six months ended Jan. 31, 2008 was 0.55% of the Fund's
average daily net assets, including an adjustment under the terms of the
performance incentive arrangement.

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, 2008 was 0.06%
of the Fund's average daily net assets.

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, 2008, other expenses paid to this company were $310.

Compensation of Board members includes, for a former Board Chair, compensation
as well as retirement benefits. Certain other aspects of a 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.

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:

- -  Class A $19.50

- -  Class B $20.50

- -  Class C $20.00

The Fund 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.

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

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

 28 RIVERSOURCE LARGE CAP VALUE FUND -- 2008 SEMIANNUAL REPORT


attributable to Class R2, Class R3 and Class R4 shares for the provision of
various administrative, recordkeeping, communication and educational services.

The Fund has an agreement with RiverSource Distributors, Inc. (the Distributor)
for distribution and shareholder services. Prior to Oct. 1, 2007, Ameriprise
Financial Services, Inc. also served as a principal underwriter and distributor
to the Fund. 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.

Sales charges received by the Distributor for distributing Fund shares were
$21,809 for Class A, $7,247 for Class B and $43 for Class C for the six months
ended Jan. 31, 2008.

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, 2008, the Investment Manager and its
affiliates waived/reimbursed certain fees and expenses such that net expenses
(excluding fees and expenses of acquired funds) were 1.34% for Class R2, 1.09%
for Class R3 and 0.83% for Class R4. Of these waived/reimbursed fees and
expenses, the plan administration services fees at the class level were $5, $5
and $47 for Class R2, Class R3 and Class R4, respectively. In addition, the
Investment Manager and its affiliates have contractually agreed to waive certain
fees and expenses until July 31, 2008, such that net expenses (excluding fees
and expenses of acquired funds), before giving effect to any performance
incentive adjustment, will not exceed 1.13% of the Fund's average daily net
assets for Class R4, unless sooner terminated at the discretion of the Board.

During the six months ended Jan. 31, 2008, the Fund's custodian and transfer
agency fees were reduced by $1,594 as a result of earnings and bank fee credits
from overnight cash balances. The Fund pays custodian fees to Ameriprise Trust
Company, a subsidiary of Ameriprise Financial.

3. SECURITIES TRANSACTIONS

Cost of purchases and proceeds from sales of securities (other than short-term
obligations) aggregated $9,040,527 and $24,366,759, 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. The cost of the
Fund's purchases and proceeds from sales of shares of the RiverSource Short-Term
Cash Fund aggregated $17,215,766 and $18,941,321, respectively, for the six
months ended Jan. 31, 2008.

6. BANK BORROWINGS

The Fund has entered into a revolving credit facility 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

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

 30 RIVERSOURCE LARGE CAP VALUE FUND -- 2008 SEMIANNUAL REPORT


emergency purposes. The credit facility became effective on Oct. 18, 2007,
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 $500 million.
Interest is 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 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. Under the prior credit facility, a Fund paid
interest on its outstanding 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. The Fund had no borrowings during the six months ended Jan. 31,
2008.

7. CONCENTRATION OF RISK

SECTOR RISK

If a fund emphasizes one or more economic sectors, it may be more susceptible to
the financial, market or economic events affecting the particular issuers and
industries in which it invests than funds that do not emphasize particular
sectors. The more a fund diversifies, the more it spreads risk and potentially
reduces the risks of loss and volatility.

8. 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

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

                  RIVERSOURCE LARGE CAP VALUE FUND -- 2008 SEMIANNUAL REPORT  31


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.

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.
