4  RIVERSOURCE CASH MANAGEMENT FUND -- 2009 ANNUAL REPORT



MANAGER COMMENTARY -------------------------------------------------------------

Dear Shareholder,

RiverSource Cash Management Fund (the Fund) Class A shares advanced 0.79% for
the annual period. The Fund's annualized simple yield was 0.10% and its
annualized compound yield was also 0.10% for the seven-day period ended July 31,
2009.(* ) The Fund serves as a conservative, shorter-term investment choice for
individuals seeking current income.

SIGNIFICANT PERFORMANCE FACTORS
The annual period ended July 31, 2009 was one characterized by historic shocks
to the global financial system resulting in a liquidity freeze in the financial
markets and dramatic Fed action to restart the flow of credit, increase
confidence and jump start an economic recovery. These events had the greatest
impact on money markets during the period.

Shocks to the global financial system in September 2008 caused market
participants to reduce risk from their investment portfolios in such dramatic
fashion to ultimately create credit, liquidity and confidence crises that lasted
largely through the first quarter of 2009. In response to these crises and in an
effort to revive confidence, the Fed, the U.S. Treasury Department and the
Federal Deposit Insurance Corporation (FDIC), along with several global banking
bodies, created a host of unprecedented programs and a new framework within
which to improve liquidity and restart the flow of credit. For example, in an
effort to restore confidence in retail and institutional money market funds, the
U.S. Treasury Department created a Temporary Guarantee Program for Money

MANAGER COMMENTARY (continued) -------------------------------------------------


Market Funds. The Federal Reserve Bank of Boston implemented the Asset-Backed
Commercial Paper Money Market Mutual Fund Liquidity Facility (AMLF) to provide a
source of liquidity for asset-backed securities held by money market funds. The
Federal Reserve Bank of New York created a Commercial Paper Funding Facility
(CPFF) to provide liquidity to U.S. issuers of both unsecured commercial paper
and asset-backed commercial paper through what is known as a special purpose
vehicle. In other words, the CPFF was designed to provide a backstop financing
facility to ensure that corporations would have the ability to repay maturing
debt and finance current operations by purchasing commercial paper directly. To
further address credit and liquidity concerns, FDIC-insured depository
institutions, such as banks, thrifts and certain holding companies, were given
the ability to issue senior unsecured debt guaranteed under the Temporary
Liquidity Guarantee Program (TLGP).

The reducing of risk from portfolios through these months caused credit spreads
(the difference in yields between higher quality and lower quality securities)
to widen dramatically. Spreads, however, rebounded significantly during the last
four months or so of the annual period, as investors began to feel comfortable
that the measures put in place had eased credit concerns. The narrowing of
credit spreads, together with the Fed reducing its targeted federal funds rate
by more than 175 basis points (1.75%) to a range of 0% to 0.25% and
communicating that it intended to keep rates near zero for some time, caused
money market yields to move dramatically lower during the annual period.

At the same time, the combination of all of these factors led the money market
yield curve, or spectrum of maturities, to flatten over the annual period as a
whole, meaning the difference between yields at the short-term end of the money
market yield curve and the longer-term end narrowed.

Following the unprecedented events of September 2008, our focus was to increase
the Fund's liquidity by reducing its average weighted maturity. Since we
strategically kept the portfolio positioned short for the majority of the annual
period, the Fund did not fully benefit from the flattening of the money market
yield curve, but preserving liquidity within a rather illiquid market was of
primary importance to us. The weighted average

- --------------------------------------------------------------------------------
6  RIVERSOURCE CASH MANAGEMENT FUND -- 2009 ANNUAL REPORT



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


maturity of a money market fund is a measure of its price sensitivity to changes
in interest rates. Throughout most of the annual period, we favored U.S.
Treasury, agency and other government-guaranteed securities that offered, in our
view, a better risk-adjusted yield.

CHANGES TO THE FUND'S PORTFOLIO
As mentioned above, we strategically adjusted the Fund's average weighted
maturity as market conditions shifted. The Fund began the 12-month period with
an average weighted maturity of 45 days. We subsequently increased the Fund's
average weighted maturity to approximately 60 days to take advantage of the then
steepening yield curve, meaning longer-term yields declined less than shorter-
term yields. At that time, the Fed was proactively adding liquidity measures in
an effort to address liquidity concerns and credit conditions had marginally
improved. Beginning in September, we once again raised the Fund's liquidity
profile as a defensive measure, given the meltdown in the financial markets.
Between September and April, we kept the Fund's average weighted maturity in a
range of 25 to 35 days, maintaining a conservative stance. In the last months of
the annual period, as credit spreads rebounded, we began extending the Fund's
average weighted maturity in an effort to capture some incremental yield. As of
July 31, 2009, the average weighted maturity of the Fund was 55 days.

Seeking to provide a conservative vehicle for our shareholders amidst the
massive uncertainties facing the nation's financial system, we became
increasingly cautious from a credit perspective as the period progressed. We
decreased the Fund's holdings in bank and finance-related commercial paper and
increased holdings of government and agency


  The annual period ended July 31, 2009 was one characterized by historic shocks
  to the global financial system resulting in a liquidity freeze in the
  financial markets and dramatic Fed action to restart the flow of credit,
  increase confidence and jump start an economic recovery. These events had the
  greatest impact on money markets during the period.

                       RIVERSOURCE CASH MANAGEMENT FUND -- 2009 ANNUAL REPORT  7



MANAGER COMMENTARY (continued) -------------------------------------------------


securities that offered what we considered to be the greatest risk-adjusted
yield. Included among these holdings were securities that were issued under the
TLGP. Most of the Fund's holdings in government and agency securities were fixed
rate securities with one-to-three month maturities.

OUR FUTURE STRATEGY
We believe the worst of the financial crisis is likely behind us in terms of the
credit measures we use for bank and finance-related companies and that these
institutions are in a better place from a credit perspective than they were one
year prior. That said, however, the dramatic narrowing of credit spreads in the
last months of the annual period caused risk-adjusted returns in the
bank/finance sector to become overvalued in our view.

We continue to observe improvement, albeit from a low base, in economic activity
across a number of leading indicators. Such "green shoots" have caused us to re-
think whether the Fed will indeed continue to maintain its near-zero targeted
federal funds rate too far into 2010 and may ultimately have to execute its
much-talked-about exit strategy. We believe the Fed may implement such a
strategy in 2010 and we therefore intend to maintain the Fund's average weighted
maturity around 50 days during the months ahead while prudently monitoring risk-
adjusted yields.

We further intend to continue to evaluate credits to maintain the Fund's high
quality bias. We intend to make strategic decisions to balance an enhanced
liquidity profile with providing current income. We will, of course, continue to
closely monitor economic data, Fed policy and any shifts in the money market
yield curve, striving to strategically adjust the portfolio accordingly. We
intend to continue to focus on high-quality investments with minimal credit risk
while seeking competitive yields.

FUND EXPENSES EXAMPLE ----------------------------------------------------------
(UNAUDITED)

As a shareholder of the Fund, you incur two types of costs: (1) transaction
costs, including sales charges (loads); 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.

The example is based on an investment of $1,000 invested at the beginning of the
period and held for the six months ended July 31, 2009.

ACTUAL EXPENSES
The first line of the table provides information about actual account values and
actual expenses. You may use the information in this line, together with the
amount you invested, to estimate the expenses that you paid over the period.
Simply divide your account value by $1,000 (for example, an $8,600 account value
divided by $1,000 = 8.6), then multiply the result by the number in the first
line under the heading titled "Expenses paid during the period" to estimate the
expenses you paid on your account during this period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
The second line of the table provides information about hypothetical account
values and hypothetical expenses based on the Fund's actual expense ratio and an
assumed rate of return of 5% per year before expenses, which is not the Fund's
actual return. The hypothetical account values and expenses may not be used to
estimate the actual ending account balance or expenses you paid for the period.
You may use this information to compare the ongoing costs of investing in the
Fund and other funds. To do so, compare this 5% hypothetical example with the 5%
hypothetical examples that appear in the shareholder reports of the other funds.

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

10  RIVERSOURCE CASH MANAGEMENT FUND -- 2009 ANNUAL REPORT



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


(c) RiverSource Investments, LLC (the Investment Manager) and its affiliates
    have contractually agreed to waive certain fees and to absorb certain
    expenses until Sept. 30, 2010, unless sooner terminated at the discretion of
    the Fund's Board, such that net expenses (before any voluntary expense
    limitations) will not exceed 0.65% for Class A, 1.31% for Class B, 1.31% for
    Class C, 0.37% for Class I, 0.42% for Class R5, 0.67% for Class W and 0.57%
    for Class Y. Any amounts waived will not be reimbursed by the Fund. This
    change was effective Aug. 1, 2009. If this change had been in place for the
    entire six month period ended July 31, 2009, the actual expenses paid
    (before any voluntary expense limitations) would have been $3.24 for Class
    A, $6.53 for Class B, $6.53 for Class C, $1.85 for Class I, $2.09 for Class
    R5, $3.34 for Class W and $2.84 for Class Y; the hypothetical expenses paid
    (before any voluntary expense limitations) would have been $3.28 for Class
    A, $6.59 for Class B, $6.59 for Class C, $1.87 for Class I, $2.12 for Class
    R5, $3.38 for Class W and $2.87 for Class Y. Additionally, the Investment
    Manager and its affiliates voluntarily waived or absorbed expenses of the
    Fund during the six months ended July 31, 2009, and may do so from time to
    time for the purpose of allowing the Fund to avoid a negative net yield or
    to increase the Fund's positive net yield. The Fund's yield would be
    negative if Fund expenses exceed Fund income. Any such expense limitation is
    voluntary and may be revised or terminated at any time without notice.

FAIR VALUE MEASUREMENTS


Statement of Financial Accounting Standards No. 157 (SFAS 157) requires
disclosure regarding the inputs and valuation techniques used to measure fair
value and any changes in valuation inputs or techniques. In addition,
investments shall be disclosed by major category.

SFAS 157 establishes a fair value hierarchy for inputs used in measuring fair
value that maximizes the use of observable inputs and minimizes the use of
unobservable inputs by prioritizing that the most observable input be used when
available. Observable inputs are those that market participants would use in
pricing an investment based on market data obtained from sources independent of
the reporting entity. Unobservable inputs are those that reflect the Fund's
assumptions about the information market participants would use in pricing an
investment. An investment's level within the fair value hierarchy is based on
the lowest level of any input that is deemed significant to the asset or
liability's fair value measurement. When a valuation uses multiple inputs from
varying levels of the hierarchy, the hierarchy level is determined based on the
lowest level input or inputs that are significant to the fair value measurement
in its entirety. The input levels are not necessarily an indication of the risk
or liquidity associated with investments at that level. For example, certain
U.S. government securities are generally high quality and liquid, however, they
are reflected as Level 2 because the inputs used to determine fair value may not
always be quoted prices in an active market.

Fair value inputs are summarized in the three broad levels listed below:

     - Level 1 -- Valuations based on quoted prices for investments in active
       markets that the Fund has the ability to access at the measurement date.
       Valuation adjustments are not applied to Level 1 investments.

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

     - Level 3 -- Valuations based on significant unobservable inputs (including
       the Fund's own assumptions and judgment in determining the fair value of
       investments).

Inputs that are used in determining fair value of an investment may include
price information, credit data, volatility statistics, and other factors. These
inputs can be either observable or unobservable. The availability of observable
inputs can vary between investments, and is affected by various factors such as
the type of investment, and the volume and level of activity for that investment
or similar investments in the marketplace. The inputs will be considered by the
Fund Administrator, along with any other relevant factors in the calculation of
an investment's fair value. The Fund uses prices and inputs that are current as
of the measurement date, which may include periods of market dislocations.
During these periods, the availability of prices and inputs may be reduced for
many investments. This condition could cause an investment to be reclassified
between the various levels within the hierarchy.

Short-term securities are valued using amortized cost, as permitted under Rule
2a-7 of the Investment Company Act of 1940, as amended. Generally, amortized
cost approximates the current fair value of these securities, but because the
value is not obtained from a quoted price in an active market, such securities
are reflected as Level 2.

Investments falling into the Level 3 category are primarily supported by quoted
prices from brokers and dealers participating in the market for those
investments. However, these may be classified as

- --------------------------------------------------------------------------------
16  RIVERSOURCE CASH MANAGEMENT FUND -- 2009 ANNUAL REPORT



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

FAIR VALUE MEASUREMENTS (CONTINUED)




Level 3 investments due to lack of market transparency and corroboration to
support these quoted prices, or the inability to find more than a single broker
or dealer that provides a quote for the investment. Additionally, valuation
models may be used as the pricing source for any remaining investments
classified as Level 3. These models rely on one or more significant unobservable
inputs and/or significant assumptions by the Fund Administrator. Inputs used in
a valuation model may include, but are not limited to, financial statement
analysis, discount rates and estimated cash flows, and comparable company data.

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

NOTES TO FINANCIAL STATEMENTS --------------------------------------------------

1. ORGANIZATION

RiverSource Cash Management Fund (the Fund) is a series of RiverSource Money
Market Series, Inc. and is registered under the Investment Company Act of 1940,
as amended (the 1940 Act) as a diversified, open-end management investment
company. RiverSource Money Market Series, Inc. has 10 billion authorized shares
of capital stock that can be allocated among the separate series as designated
by the Fund's Board of Directors (the Board). The Fund invests primarily in
money market instruments.

The Fund offers Class A, Class B, Class C, Class I, Class R5, Class W and Class
Y shares.

- -  Class A shares have no sales charge.

- -  Class B shares may be subject to a contingent deferred sales charge (CDSC)
   and automatically convert to Class A shares one month after the completion of
   the eighth year of ownership if originally purchased in a RiverSource fund on
   or after May 21, 2005 or originally purchased in a Seligman fund on or after
   June 13, 2009. Class B shares originally purchased in a RiverSource fund
   prior to May 21, 2005 will convert to Class A shares in the ninth calendar
   year of ownership. Class B shares originally purchased in a Seligman fund
   prior to June 13, 2009 will convert to Class A shares in the month prior to
   the ninth year of ownership.

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

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

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

At July 31, 2009, RiverSource Investments, LLC (the Investment Manager) and
affiliated funds-of-funds in the RiverSource Family of Funds owned 100% of Class
I shares, and the Investment Manager owned 100% of 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.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

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
Pursuant to Rule 2a-7 of the 1940 Act, all securities are valued daily at
amortized cost, which approximates market value.

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 (which includes net short-term capital gains) to
shareholders. No provision for income or excise taxes is thus required.

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.

DIVIDENDS TO SHAREHOLDERS
Dividends from net investment income, declared daily and payable monthly, are
reinvested in additional shares of the Fund at net asset value or payable in
cash.

OTHER
Security transactions are accounted for on the date securities are purchased or
sold. Interest income, including amortization of premium and discount, is
recognized daily.

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

3. EXPENSES AND SALES CHARGES

INVESTMENT MANAGEMENT SERVICES FEES
Under an Investment Management Services Agreement, the Investment Manager
determines which securities will be purchased, held or sold. The management fee
is an annual fee that is equal to a percentage of the Fund's average daily net
assets that declines from 0.33% to 0.15% as the Fund's net assets increase. The
management fee for the year ended July 31, 2009 was 0.29% of the Fund's average
daily net assets.

ADMINISTRATIVE SERVICES FEES
Under an Administrative Services Agreement, the Fund pays Ameriprise Financial,
Inc. (Ameriprise Financial), parent company of the Investment Manager, an annual
fee for administration and accounting services equal to a percentage of the
Fund's average daily net assets that declines from 0.06% to 0.03% as the Fund's
net assets increase. The fee for year ended July 31, 2009 was 0.05% of the
Fund's average daily net assets.

OTHER FEES
Other expenses are for, among other things, certain expenses of the Fund or the
Board including: Fund boardroom and office expense, employee compensation,
employee health and retirement benefits, and certain other expenses. Payment of
these Fund and Board expenses is facilitated by a company providing limited
administrative services to the Fund and the Board. For the year ended July 31,
2009, other expenses paid to this company were $32,242.

COMPENSATION OF BOARD MEMBERS
Under a Deferred Compensation Plan (the Plan), the board members who are not
"interested persons" of the Fund under the 1940 Act 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 funds in the RiverSource Family
of Funds. The Fund's liability for these amounts is adjusted for market value
changes and remains in the funds until distributed in accordance with the Plan.

TRANSFER AGENCY FEES
Under a Transfer Agency Agreement, RiverSource Service Corporation (the Transfer
Agent) maintains Fund shareholder accounts and records and provides Fund
shareholder services. The Fund pays the Transfer Agent an annual account-based
fee at a rate equal to $22.00 for Class A, $23.00 for Class B and $22.50 for
Class C for this service. The Transfer Agent also charges an annual fee of $3
per account serviced directly by the Fund or its designated agent for Class A,
Class B and Class C shares. The Fund also pays the Transfer Agent an annual
asset-based fee at a rate of 0.05% of the Fund's average daily net assets
attributable to Class R5 and Class Y shares and an annual asset-based fee at a

- --------------------------------------------------------------------------------
32  RIVERSOURCE CASH MANAGEMENT FUND -- 2009 ANNUAL REPORT



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


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 the 12 month period from the date the account
becomes inactive. These fees are included in the transfer agency fees in the
Statement of Operations.

PLAN ADMINISTRATION SERVICES FEES
Under a Plan Administration Services Agreement with the Transfer Agent, the Fund
pays an annual fee at a rate of 0.15% of the Fund's average daily net assets
attributable to Class Y shares for the provision of various administrative,
recordkeeping, communication and educational services.

DISTRIBUTION FEES
The Fund has an agreement with RiverSource Fund Distributors, Inc. (the
Distributor) for distribution and shareholder services. Under a Plan and
Agreement of Distribution pursuant to Rule 12b-1, the Fund pays a fee at an
annual rate of up to 0.10% of the Fund's average daily net assets attributable
to Class A and Class W shares and a fee at an annual rate of up to 0.85% and
0.75% of the Fund's average daily net assets attributable to Class B and Class C
shares, respectively. At July 31, 2009, the Fund paid an annual rate of 0.75% of
the Fund's average daily net assets attributable to Class B and Class C shares.

The amount of distribution expenses incurred by the Distributor and not yet
reimbursed (unreimbursed expense) was approximately $7,863,000 and $89,000 for
Class B and Class C shares, respectively. These amounts are based on the most
recent information available as of April 30, 2009, and may be recovered from
future payments under the distribution plan or CDSC. To the extent the
unreimbursed expense has been fully recovered, the distribution fee is reduced.

SALES CHARGES
CDSCs received by the Distributor for distributing Fund shares were $356,908 for
Class B and $10,835 for Class C for the year ended July 31, 2009.

EXPENSES WAIVED/REIMBURSED BY THE INVESTMENT MANAGER AND ITS AFFILIATES
For the year ended July 31, 2009, the Investment Manager and its affiliates
waived/reimbursed certain fees and expenses such that net expenses were as
follows:

<Table>
                                                   
Class A.............................................  0.61%

Class W.............................................  0.64
Class Y.............................................  0.58
</Table>




- --------------------------------------------------------------------------------
                      RIVERSOURCE CASH MANAGEMENT FUND -- 2009 ANNUAL REPORT  33



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

The waived/reimbursed fees and expenses for the transfer agency fees and other
fees at the class level were as follows:

<Table>
                                               
Class A.........................................  $4,989,753
Class B.........................................     532,848
Class C.........................................      44,231
Class R5........................................           1
Class W.........................................      43,623
Class Y.........................................      17,084
</Table>


Under an agreement which was effective until July 31, 2009, the Investment
Manager and its affiliates contractually agreed to waive certain fees and
expenses such that net expenses, would not exceed the following percentage of
the class' average daily net assets:

<Table>
                                                   
Class A.............................................  0.66%
Class B.............................................  1.32
Class C.............................................  1.31
Class I.............................................  0.43
Class R5............................................  0.48
Class W.............................................  0.73
Class Y.............................................  0.63
</Table>


Effective Aug. 1, 2009, the Investment Manager and its affiliates have
contractually agreed to waive certain fees and expenses until Sept. 30, 2010,
unless sooner terminated at the discretion of the Board, such that net expenses
will not exceed the following percentage of the class' average daily net assets:

<Table>
                                                   
Class A.............................................  0.65%
Class B.............................................  1.31
Class C.............................................  1.31
Class I.............................................  0.37
Class R5............................................  0.42
Class W.............................................  0.67
Class Y.............................................  0.57
</Table>


In addition, from time to time, the Investment Manager and its affiliates may
waive or absorb expenses of the Fund for the purpose of allowing the Fund to
avoid a negative net yield or to increase the Fund's positive net yield. The
Fund's yield would be negative if Fund expenses exceed Fund income. Any such
expense limitation is voluntary and may be revised or terminated at any time
without notice.

EARNINGS AND BANK FEE CREDITS
During the year ended July 31, 2009, the Fund's custodian and transfer agency
fees were reduced by $96,895 as a result of earnings and bank fee credits from

- --------------------------------------------------------------------------------
34  RIVERSOURCE CASH MANAGEMENT FUND -- 2009 ANNUAL REPORT



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


overnight cash balances. Effective Dec. 15, 2008, the Fund pays custodian fees
to JPMorgan Chase Bank, N.A. For the period from Aug. 1, 2008 to Dec. 15, 2008
the Fund paid custodian fees amounting to $135,836 to Ameriprise Trust Company,
a subsidiary of Ameriprise Financial.

TEMPORARY MONEY MARKET FUND GUARANTY PROGRAM
On Oct. 6, 2008, the Fund applied to participate in the initial term of the U.S.
Department of Treasury's Temporary Guarantee Program for Money Market Funds (the
Program), through Dec. 18, 2008 (the Initial Term), after obtaining the approval
of the Board, including a majority of the independent directors. On Dec. 2,
2008, the Board approved the Fund's participation in an extension of the Program
through April 30, 2009 (the First Extended Term). On April 8, 2009, the Board
approved the Fund's participation in an extension of the Program through Sept.
18, 2009 (the Second Extended Term). The Fund filed the extension notice with
the U.S. Department of Treasury on April 13, 2009 to participate in the Second
Extended Term of the Program.

The Program covers shareholders of each participating money market fund for
amounts they held in such funds as of the close of business on Sept. 19, 2008.
Any increase in the number of shares of that fund held by a shareholder after
the close of business on Sept. 19, 2008 will not be guaranteed. Any purchase of
shares of a participating money market fund after the close of business on Sept.
19, 2008 will not be guaranteed. If shares of a participating fund held by a
shareholder as of the close of business on Sept. 19, 2008 are sold before the
guarantee is called upon, then the guarantee will only cover the lesser of (i)
the number of fund shares held by the shareholder as of the close of business on
Sept. 19, 2008, or (ii) the number of fund shares held by the shareholder on the
date the guarantee is called upon. A participating fund shareholder who sells
all of his or her shares after Sept. 19, 2008 (and before the guarantee is
called upon) will no longer be covered by the guarantee, even if the shareholder
subsequently reinvests in the Fund or in another fund that is participating in
the Program.

Under the terms of the Program, the guarantee is called upon with respect to the
Fund if the Board of the Fund makes a determination to liquidate the Fund. For
shares covered by the guarantee, any difference between the amount a shareholder
received in connection with the liquidation and $1.00 per share (a guarantee
payment) will be covered by the U.S. Department of Treasury under the Program,
subject to the overall amount available to all funds participating in the
Program. Guarantee payments under the Program will not exceed the amount
available in the Program (at inception of the Program, approximately $50 billion
was available to support guarantee payments).


- --------------------------------------------------------------------------------
                      RIVERSOURCE CASH MANAGEMENT FUND -- 2009 ANNUAL REPORT  35



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

During the year ended July 31, 2009, the Fund paid upfront fees to the U.S.
Department of Treasury to participate in the Program. For the initial three-
month term of the Program that expired on Dec. 18, 2008, the fee incurred by the
Fund was 0.015% of its net asset value as of the close of business Sept. 19,
2008. The fee to participate in the First Extended Term of the Program through
April 30, 2009 required an additional payment in the amount of 0.022% of its net
asset value as of Sept. 19, 2008. The fee to participate in the Second Extended
Term required an additional payment in the amount of 0.023% of its net asset
value as of Sept. 19, 2008. The fees are being amortized over the period of the
participation in the Program and are shown on the Fund's Statement of
Operations. The cost to participate will be borne by the Fund without regard to
any expense limitation currently in effect, if any. However, to the extent the
Investment Manager voluntarily limits the expenses of the Fund for the purpose
of supporting its yield, the cost to participate in the Second Extended Term may
be absorbed by the Investment Manager. The Program expired on the close of
business on Sept. 18, 2009.

4. BANK BORROWINGS

The Fund has entered into a revolving credit facility with a syndicate of banks
led by JPMorgan Chase Bank, N.A. (the Administrative Agent), whereby the Fund
may borrow for the temporary funding of shareholder redemptions or for other
temporary or emergency purposes. The credit facility became effective on Oct.
16, 2008, replacing a prior credit facility. The credit facility agreement,
which is a collective agreement between the Fund and certain other funds in the
RiverSource Family of Funds, severally and not jointly, permits collective
borrowings up to $475 million. The borrowers shall have the right, upon written
notice to the Administrative Agent to request an increase of up to $175 million
in the aggregate amount of the credit facility from new or existing lenders,
provided that the aggregate amount of the credit facility shall at no time
exceed $650 million. Participation in such increase by any existing lender shall
be at such lender's sole discretion. Interest is charged to each Fund based on
its borrowings at a rate equal to the federal funds rate plus 0.75%. Each
borrowing under the credit facility matures no later than 60 days after the date
of borrowing. The Fund also pays a commitment fee equal to its pro rata share of
the amount of the credit facility at a rate of 0.06% per annum, in addition to
an upfront fee equal to its pro rata share of 0.02% of the amount of the credit
facility. The Fund had no borrowings during the year ended July 31, 2009.

Under the prior credit facility which was effective until Oct. 15, 2008, the
Fund had entered into a revolving credit facility with a syndicate of banks
headed by JPMorgan Chase Bank, N.A., whereby the Fund was permitted to borrow
for the

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

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



temporary funding of shareholder redemptions or for other temporary or emergency
purposes. The credit facility agreement, which was a collective agreement
between the Fund and certain other RiverSource funds, severally and not jointly,
permitted collective borrowings up to $500 million. Interest was charged to each
Fund based on its borrowings at a rate equal to the federal funds rate plus
0.30%. Each borrowing under the credit facility matured no later than 60 days
after the date of borrowing. The Fund also paid a commitment fee equal to its
pro rata share of the amount of the credit facility at a rate of 0.06% per
annum.

5. INVESTMENTS IN STRUCTURED INVESTMENT VEHICLES

In 2007 and 2008, structured investment vehicles (SIVs) generally experienced a
significant decrease in liquidity as a result of the reduction in demand for
asset-backed commercial paper as well as the lack of liquidity and overall
volatility in the markets for the collateral underlying these investment
structures. On April 29, 2009, the Fund disposed of its remaining $41.7 million
position in WhistleJacket Capital LLC (WJC) and the Fund held no other SIV
positions as of July 31, 2009.

WJC breached a financial covenant on Feb. 11, 2008 relating to the market value
of its underlying collateral, resulting in the occurrence of an "enforcement
event." This resulted in the appointment of receivers on Feb. 12, 2008. On Feb.
15, 2008, the receivers declared WJC to be insolvent. The Fund's positions in
WJC went into default as of their respective maturity dates, Feb. 25, 2008 ($35
million) and March 20, 2008 ($40 million). The Fund received a partial payment
totaling $17.3 million from WJC on Oct. 27, 2008 reducing the remaining total
outstanding principal amount for WJC on that date to $57.7 million. Ameriprise
Financial purchased $16 million of WJC from the Fund between March 6, 2009 and
April 21, 2009 for cash at a price equal to amortized cost plus accrued interest
in accordance with Rule 17a-9 of the 1940 Act. The Fund recorded $3.5 million as
payments by an affiliate, which is equal to the aggregate difference between the
fair value of WJC and the cash received from Ameriprise Financial on each
purchase date. On April 29, 2009, the Fund chose the cash payout option in the
restructuring of WJC and received cash proceeds totaling $33.4 million on its
remaining $41.7 million principal in WJC. The Fund recognized a loss of $8.3
million on the transaction. The loss recognized on April 29, 2009 was not
material to the Fund's $1.00 net asset value per share.

Pursuant to the Fund's pricing procedures, securities are valued utilizing the
amortized cost method permitted in accordance with Rule 2a-7 under the 1940 Act.
Rule 2a-7 also requires periodic monitoring (Shadow Pricing) of the

- --------------------------------------------------------------------------------
                      RIVERSOURCE CASH MANAGEMENT FUND -- 2009 ANNUAL REPORT  37



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


deviation between the net asset value per share of the Fund using the amortized
cost method and the net asset value per share determined based on fair value to
ensure that the amortized cost method continues to provide an appropriate net
asset value per share for the Fund in accordance with Rule 2a-7.

For the year ended July 31, 2009, all investments held by the Fund, including
WJC, were valued at amortized cost in compliance with Rule 2a-7 procedures. In
addition, for the same time period the deviations resulting from the Shadow
Pricing procedures were not material to the Fund's $1.00 net asset value per
share.

6. PAYMENTS BY AFFILIATE

On Sept. 15, 2008, Lehman Brothers Holdings Inc. (Lehman Brothers) filed a
Chapter 11 bankruptcy petition. At that time, the Fund owned $40 million in
medium term commercial paper issued by Lehman Brothers (the Lehman Notes). The
value of the Lehman Notes declined following Lehman Brothers filing of its
bankruptcy petition. From Sept. 16, 2008 through Sept. 30, 2008, Ameriprise
Financial purchased the total $40 million par of the Lehman Notes from the Fund
for cash at a price equal to amortized cost plus accrued interest in accordance
with Rule 17a-9 of the 1940 Act. The Fund recorded $30.3 million as a payment by
affiliate, which is equal to the aggregate difference between the fair value of
the Lehman Notes at each purchase date and the cash received from Ameriprise
Financial.

As discussed in Note 5, Ameriprise Financial purchased a position of the Fund's
SIV holding of WJC from the Fund. The Fund recorded $3.5 million as a payment by
affiliate, which is equal to the aggregate difference between the fair value of
WJC at each purchase date and the cash received from Ameriprise Financial.

From June 8, 2009 through July 31, 2009, due to realized losses of the Fund,
Ameriprise Financial has paid approximately $1.0 million to the Fund to provide
support to the Fund's $1.00 net asset value per share. These amounts are
recorded as increase from payments by affiliate on the Statement of Operations.
Subsequent to July 31, 2009 and through September 21, 2009 (date of issuance of
the Fund's financial statements), additional support payments have been made by
Ameriprise Financial amounting to approximately $8.2 million.

7. FEDERAL TAX INFORMATION

Net investment income (loss) and net realized gains (losses) may differ for
financial statement and tax purposes primarily because of post-October losses.
The character of distributions made during the year from net investment income

- --------------------------------------------------------------------------------
38  RIVERSOURCE CASH MANAGEMENT FUND -- 2009 ANNUAL REPORT



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



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.

In the Statement of Assets and Liabilities, as a result of permanent book-to-tax
differences, undistributed net investment income has been increased by $111,664
and accumulated net realized loss has been increased by $111,664.

The tax character of distributions paid for the years indicated is as follows:

At July 31, 2009, the components of distributable earnings on a tax basis are as

Undistributed ordinary income..................  $    240,613
Undistributed accumulated long-term gain.......  $         --
Accumulated realized loss......................  $(15,893,171)
Unrealized appreciation (depreciation).........  $    (64,878)
</Table>


For federal income tax purposes, the Fund had a capital loss carry-over of
$7,363,623 at July 31, 2009, that if not offset by capital gains will expire as
follows:

<Table>
<Caption>
 2016        2017
       
$6,554    $7,357,069
</Table>


Because the measurement periods for a regulated investment company's income are
different for excise tax purposes versus income tax purposes, special rules are
in place to protect the amount of earnings and profits needed to support excise
tax distributions. As a result, the Fund is permitted to treat net capital
losses realized between Nov. 1, 2008 and its fiscal year end (post-October loss)
as occurring on the first day of the following tax year. At July 31, 2009, the
Fund had a post-October loss of $8,529,548 that is treated for income tax
purposes as occurring on Aug. 1, 2009.


- --------------------------------------------------------------------------------
                      RIVERSOURCE CASH MANAGEMENT FUND -- 2009 ANNUAL REPORT  39



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

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. There is no assurance that the Fund will be able to utilize all of its
capital loss carry-over before it expires.

8. SUBSEQUENT EVENTS

Management has evaluated Fund related events and transactions that occurred
during the period from the date of the Statement of Assets and Liabilities
through Sept. 21, 2009, the date of issuance of the Fund's financial statements.
There were no events or transactions that occurred during the period that
materially impacted the amounts or disclosures in the Fund's financial
statements, other than the expiration of the Temporary Money Market Fund
Guaranty Program discussed in Note 3, the payments by affiliate discussed in
Note 6, and the offering of Class R2 shares as noted below.

Effective Aug. 3, 2009, the Fund offers Class R2 shares.

9. 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 (now known as
RiverSource) 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 (the District Court).
In response to defendants' motion to dismiss the complaint, the District 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 (the Eighth Circuit)
on August 8, 2007. On April 8, 2009, the Eighth Circuit reversed summary
judgment and remanded to the District Court for further proceedings. On August
6, 2009, defendants filed a writ of certiorari with the U.S. Supreme Court,
asking the U.S. Supreme Court to stay the District Court proceedings while the
U.S. Supreme Court considers and rules in a case captioned Jones v.

Harris Associates, which involves issues of law similar to those presented in
the Gallus case.

In December 2005, without admitting or denying the allegations, American Express
Financial Corporation (AEFC, which is now known as Ameriprise Financial, Inc.
(Ameriprise Financial)), entered into settlement agreements with the Securities
and Exchange Commission (SEC) and Minnesota Department of Commerce (MDOC)
related to market timing activities. As a result, AEFC was censured and ordered
to cease and desist from committing or causing any violations of certain
provisions of the Investment Advisers Act of 1940, the Investment Company Act of
1940, and various Minnesota laws. AEFC agreed to pay disgorgement of $10 million
and civil money penalties of $7 million. AEFC also agreed to retain an
independent distribution consultant to assist in developing a plan for
distribution of all disgorgement and civil penalties ordered by the SEC in
accordance with various undertakings detailed at
http://www.sec.gov/litigation/admin/ia-2451.pdf. Ameriprise Financial and its
affiliates have cooperated with the SEC and the MDOC in these legal proceedings,
and have made regular reports to the RiverSource Funds' Boards of
Directors/Trustees.

On November 7, 2008, RiverSource Investments, LLC, a subsidiary of Ameriprise
Financial, Inc., acquired J. & W. Seligman & Co. Incorporated (Seligman). In
late 2003, Seligman conducted an extensive internal review concerning mutual
fund trading practices. Seligman's review, which covered the period 2001-2003,
noted one arrangement that permitted frequent trading in certain open-end
registered investment companies managed by Seligman (the Seligman Funds); this
arrangement was in the process of being closed down by Seligman before September
2003. Seligman identified three other arrangements that permitted frequent
trading, all of which had been terminated by September 2002. In January 2004,
Seligman, on a voluntary basis, publicly disclosed these four arrangements to
its clients and to shareholders of the Seligman Funds. Seligman also provided
information concerning mutual fund trading practices to the SEC and the Office
of the Attorney General of the State of New York (NYAG).

In September 2006, the NYAG commenced a civil action in New York State Supreme
Court against Seligman, Seligman Advisors, Inc. (now known as RiverSource Fund
Distributors, Inc.), Seligman Data Corp. and Brian T. Zino (collectively, the
Seligman Parties), alleging, in substance, that the Seligman Parties permitted
various persons to engage in frequent trading and, as a result, the prospectus
disclosure used by the registered investment companies then managed by Seligman
was and had been misleading. The NYAG included other

- --------------------------------------------------------------------------------
                      RIVERSOURCE CASH MANAGEMENT FUND -- 2009 ANNUAL REPORT  41



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


related claims and also claimed that the fees charged by Seligman to the
Seligman Funds were excessive. On March 13, 2009, without admitting or denying
any violations of law or wrongdoing, the Seligman Parties entered into a
stipulation of settlement with the NYAG and settled the claims made by the NYAG.
Under the terms of the settlement, Seligman paid $11.3 million to four Seligman
Funds. This settlement resolved all outstanding matters between the Seligman
Parties and the NYAG. In addition to the foregoing matter, the New York staff of
the SEC indicated in September 2005 that it was considering recommending to the
Commissioners of the SEC the instituting of a formal action against Seligman and
Seligman Advisors, Inc. relating to frequent trading in the Seligman Funds.
Seligman responded to the staff in October 2005 that it believed that any action
would be both inappropriate and unnecessary, especially in light of the fact
that Seligman had previously resolved the underlying issue with the Independent
Directors of the Seligman Funds and made recompense to the affected Seligman
Funds. There have been no further developments with the SEC on this matter.

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

42  RIVERSOURCE CASH MANAGEMENT FUND -- 2009 ANNUAL REPORT



REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ------------------------

TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF
RIVERSOURCE CASH MANAGEMENT FUND:


We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of RiverSource Cash Management Fund (the Fund) (of
the RiverSource Money Market Series, Inc.) as of July 31, 2009, and the related
statement of operations for the year then ended, the statements of changes in
net assets for each of the two years in the period then ended, and the financial
highlights for each of the three years in the period then ended. These financial
statements and financial highlights are the responsibility of the Fund's
management. Our responsibility is to express an opinion on these financial
statements and financial highlights based on our audits. The financial
highlights of the Fund for the periods presented through July 31, 2006, were
audited by other auditors whose report dated September 20, 2006, expressed an
unqualified opinion on those financial highlights.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements and financial highlights are free of material misstatement. We were
not engaged to perform an audit of the Fund's internal control over financial
reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the
circumstances, but not for the purpose of expressing an opinion on the
effectiveness of the Fund's internal control over financial reporting.
Accordingly, we express no such opinion. An audit also includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements and financial highlights, assessing the accounting principles used
and significant estimates made by management, and evaluating the overall
financial statement presentation. Our procedures included confirmation of
securities owned as of July 31, 2009, by correspondence with the custodian and
brokers, or by other appropriate auditing procedures where replies from brokers
were not received. We believe that our audits provide a reasonable basis for our
opinion.

                      RIVERSOURCE CASH MANAGEMENT FUND -- 2009 ANNUAL REPORT  49



APPROVAL OF INVESTMENT MANAGEMENT SERVICES
AGREEMENT ----------------------------------------------------------------------

RiverSource Investments, LLC ("RiverSource Investments" or the "investment
manager"), a wholly-owned subsidiary of Ameriprise Financial, Inc. ("Ameriprise
Financial"), serves as the investment manager to the Fund. Under an investment
management services agreement (the "IMS Agreement"), RiverSource Investments
provides investment advice and other services to the Fund and all funds in the
RiverSource Family of Funds (collectively, the "Funds").

On an annual basis, the Fund's Board of Directors (the "Board"), including the
independent Board members (the "Independent Directors"), considers renewal of
the IMS Agreement. RiverSource Investments prepared detailed reports for the
Board and its Contracts Committee in March and April 2009, including reports
based on data provided by independent organizations to assist the Board in
making this determination. In addition, throughout the year, the Board (or its
committees) reviews information prepared by RiverSource Investments addressing
the services RiverSource Investments provides and Fund performance. The Board
accords particular weight to the work, deliberations and conclusions of the
Contracts, Investment Review and Compliance Committees in determining whether to
continue the IMS Agreement. At the April 7-8, 2009 in-person Board meeting,
independent legal counsel to the Independent Directors reviewed with the
Independent Directors various factors relevant to the Board's consideration of
advisory agreements and the Board's legal responsibilities related to such
consideration. Following an analysis and discussion of the factors identified
below, the Board, including all of the Independent Directors, approved renewal
of the IMS Agreement.

Nature, Extent and Quality of Services Provided by RiverSource Investments:  The
Board analyzed various reports and presentations it had received detailing the
services performed by RiverSource Investments, as well as its expertise,
resources and capabilities. The Board specifically considered many developments
during the past year concerning the services provided by RiverSource
Investments, including, in particular, the continued investment in, and
resources dedicated to, the Fund's operations, most notably, the large
investment made in the acquisition of J. & W. Seligman & Co. Incorporated,
including its portfolio management operations, personnel and infrastructure
(including the addition of two new offices in New York City and Palo Alto).
Further, in connection with the Board's evaluation of the overall package of
services provided by RiverSource Investments, the Board considered the quality
of the administrative and transfer agency services provided by RiverSource
Investments' affiliates to the Fund. The Board also reviewed the financial
condition of RiverSource Investments (and its affiliates) and each entity's
ability to carry out its responsibilities under the IMS Agreement. Further, the
Board considered RiverSource Investments' ability to retain key personnel and
its expectations in this regard. The Board also discussed the acceptability of
the terms

- --------------------------------------------------------------------------------
50  RIVERSOURCE CASH MANAGEMENT FUND -- 2009 ANNUAL REPORT



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


of the IMS Agreement (including the relatively broad scope of services required
to be performed by RiverSource Investments). The Board concluded that the
services being performed under the IMS Agreement were of a reasonably high
quality, particularly in light of recent market conditions.

Based on the foregoing, and based on other information received (both oral and
written, including the information on investment performance referenced below)
and other considerations, the Board concluded that RiverSource Investments and
its affiliates were in a position to continue to provide a high quality and
level of services to the Fund.

Investment Performance:  For purposes of evaluating the nature, extent and
quality of services provided under the IMS Agreement, the Board carefully
reviewed the investment performance of the Fund. In this regard, the Board
considered detailed reports containing data prepared by an independent
organization showing, for various periods, the performance of the Fund over
various periods, recent Fund inflows (and outflows) and a comparison of the
Fund's net assets from December 2007 to December 2008. The Board observed that
the Fund's investment performance reflected the particular management style and
the exceptionally challenging market conditions involved.

Comparative Fees, Costs of Services Provided and the Profits Realized By
RiverSource Investments and its Affiliates from their Relationships with the
Fund:  The Board reviewed comparative fees and the costs of services to be
provided under the IMS Agreement. The Board members considered detailed
comparative information set forth in an annual report on fees and expenses,
including, among other things, data (prepared by an independent organization)
showing a comparison of the Fund's expenses with median expenses paid by funds
in its peer group, as well as data showing the Fund's contribution to
RiverSource Investments' profitability. They also reviewed information in the
report comparing the fees charged to the Fund by RiverSource Investments to fees
charged to other client accounts (with similar investment strategies to those of
the Fund).

The Board accorded particular weight to the notion that the level of fees should
reflect a rational pricing model applied consistently across the various product
lines in the Funds' family, while assuring that the overall fees for each fund
are generally in line with the "pricing philosophy" (i.e., that the total
expense ratio of each fund (excluding the effect of a performance incentive
adjustment, if applicable), with few exceptions, is at or below the median
expense ratio of funds in the same comparison group). The Board took into
account that the

- --------------------------------------------------------------------------------
                      RIVERSOURCE CASH MANAGEMENT FUND -- 2009 ANNUAL REPORT  51



APPROVAL OF INVESTMENT MANAGEMENT SERVICES
AGREEMENT (continued) ----------------------------------------------------------


Fund's total expense ratio (after considering proposed expense caps/waivers)
approximated the peer group's median expense ratio.

The Board also considered the expected profitability of RiverSource Investments
and its affiliates in connection with RiverSource Investments providing
investment management services to the Fund. In this regard, the Board referred
to a detailed profitability report, discussing the profitability to RiverSource
Investments and Ameriprise Financial from managing and operating the Fund,
including data showing comparative profitability over the past two years. The
Board also considered the services acquired by the investment manager through
the use of commission dollars paid by the Funds on portfolio transactions. The
Board noted that the fees paid by the Fund should permit the investment manager
to offer competitive compensation to its personnel, make necessary investments
in its business and earn an appropriate profit. The Board concluded that
profitability levels were reasonable.

Economies of Scale to be Realized:  The Board also considered the economies of
scale that might be realized by RiverSource Investments as the Fund grows and
took note of the extent to which Fund shareholders might also benefit from such
growth. The Board considered that the IMS Agreement provides for lower fees as
assets increase at pre-established breakpoints and concluded that the IMS
Agreement satisfactorily provided for sharing these economies of scale.

Based on the foregoing, the Board, including all of the Independent Directors,
concluded that the investment management service fees were fair and reasonable
in light of the extent and quality of services provided. In reaching this
conclusion, no single factor was determinative. On April 8, 2009, the Board,
including all of the Independent Directors, approved the renewal of the IMS
Agreement for an additional annual period.
