Individual security ratings are based on information from Standard & Poor's
Corp. and Moody's Investors Service. If a rating is unavailable, the rating is
determined through an internal analysis, if appropriate. 3.5% of the portfolio
rating above was determined through internal analysis.

Investment products, including shares of mutual funds, involve investment risks
including possible loss of principal and fluctuation in value.

There are risks associated with an investment in a bond fund, including credit
risk, interest rate risk, and prepayment and extension risk. See the Fund's
prospectus for information on these and other risks associated with the Fund. In
general, bond prices rise when interest rates fall and vice versa. This effect
is usually more pronounced for longer-term securities. Non-investment grade
securities, commonly called "high-yield" or "junk" bonds, generally have more
volatile prices and carry more risk to principal and income than investment
grade securities.

Income from tax-exempt funds may be subject to state and local taxes and a
portion of income may be subject to the federal and/or state alternative minimum
tax for certain investors. Federal income tax rules will apply to any capital
gains distribution.

Fund holdings are as of the date given, are subject to change at any time, and
are not recommendations to buy or sell any security.

QUESTIONS & ANSWERS

>     EACH OF THE FUNDS UNDERPERFORMED THEIR RESPECTIVE LEHMAN BENCHMARK INDICES
      DUE PRIMARILY TO YIELD CURVE POSITIONING, THAT IS, THE WAY THE FUNDS WERE
      POSITIONED TO RESPOND TO CHANGES IN SHORT-TERM VS. LONG-TERM INTEREST
      RATES.

Q:    What factors most significantly affected performance during the annual
      period?

A:    The tax-exempt fixed income market produced modest but positive
      performance during the period, as a result of sharply rising rates across
      the spectrum of maturities, or yield curve. While tax-exempt yields moved
      higher across the yield curve, they did so more significantly at the
      short-term end than at the long-term end of the curve, causing a
      significant yield curve flattening. Interest rates rose largely in
      reaction to continued policy tightening by the Federal Reserve Board (the
      Fed), which hiked interest rates eight more times, bringing the targeted
      federal funds rate to 5.25% by the end of June 2006.

      Each of the Funds underperformed their respective Lehman benchmark indices
      due primarily to yield curve positioning, that is, the way the Funds were
      positioned to respond to changes in short-term vs. long-term interest
      rates. As mentioned earlier, the municipal yield curve flattened, as the
      difference in yields between short- and long-term securities narrowed.
      This flattening of the yield curve had a greater positive price impact on
      longer-term bonds than on shorter-term bonds. Thus, while the Funds'
      moderate exposure to the short-term segment of the municipal yield curve
      proved prudent, it was not enough to offset the detracting effect of the
      Funds' modest position in long-term bonds, which performed best over the
      annual period.

      A positive contributing factor to the annual performance of RiverSource
      New York Tax-Exempt Fund and RiverSource California Tax-Exempt Fund were
      their allocations to non-enhanced municipal tobacco bonds, which was a
      strong performing sector for the 12-month period. All six of the
      RiverSource state tax-exempt funds benefited from their positions in
      health care municipal bonds, which also performed well.

QUESTIONS & ANSWERS

>     GOING FORWARD, WE BELIEVE THE MAJOR FACTOR AFFECTING THE MUNICIPAL MARKET
      MAY WELL BE THE UNEXPECTED SLOWDOWN IN NEW ISSUE SUPPLY SEEN DURING THE
      FIRST SIX MONTHS OF 2006.

      Producing mixed results was exposure to bonds that were advance refunded
      during the 12 months ended June 30, 2006. Advance refunded bonds boosted
      the respective returns of RiverSource California Tax-Exempt Fund and
      RiverSource Michigan Tax-Exempt Fund and had a rather neutral effect on
      RiverSource Minnesota Tax-Exempt Fund and RiverSource Ohio Tax-Exempt
      Fund. However, the modest exposure of RiverSource Massachusetts Tax-Exempt
      Fund and RiverSource New York Tax-Exempt Fund to these strongly performing
      advance refunded bonds hurt performance. Advance refunding is a procedure
      in which a bond issuer floats a second bond at a lower interest rate, and
      the proceeds from the sale of the second bond are safely invested, usually
      in Treasury securities, which in turn, are held in escrow collateralizing
      the first bond. Given that the advance refunded bonds become, essentially,
      fully tax-exempt U.S. Treasury securities and no longer represent the
      credit risk profile of the original borrower, they often increase in value
      -- sometimes significantly.

      Detracting modestly from the RiverSource state-exempt funds of California,
      Michigan and New York was exposure to municipal bonds from Puerto Rico.
      Puerto Rico has been experiencing some fiscal distress, and the
      fundamentals of its municipal bond market deteriorated somewhat during the
      period.

      The primary reason the Funds underperformed their respective Lipper
      Municipal Debt Funds Index was their moderate exposure to bonds rated BBB
      compared to their peers. Bonds rated BBB generally outperformed higher
      quality bonds during the period.

Q:    What changes did you make to the Funds and how are they currently
      positioned?

A:    We increased holdings in single-family housing bonds in all of the
      RiverSource state tax-exempt funds but RiverSource Michigan Tax-Exempt
      Fund, as this sector offered an attractive yield during the period. In the
      RiverSource state tax-exempt funds of Massachusetts, Minnesota and Ohio,
      we established exposure to Commonwealth of

QUESTIONS & ANSWERS

      Puerto Rico municipal bonds, adding to positions on market weakness.
      Puerto Rico's government is currently working on the introduction of a
      local sales tax to raise revenues and reforms that would cut expenses.
      Should these potential fiscal remedies be enacted, Puerto Rico municipal
      bonds may be increasingly attractive to investors, given the
      triple-tax-exemption (i.e., federal, state and local) they offer.

      We increased exposure to non-enhanced municipal tobacco bonds in
      RiverSource California Tax-Exempt Fund and RiverSource New York Tax-Exempt
      Fund. We believe the litigation risks this sector has faced have been
      reduced, given the number of cases already heard, and thus we expect these
      bonds to continue to perform well going forward. We added to each of the
      RiverSource state tax-exempt funds' exposure to bonds rated BBB on a
      highly selective basis. Given anticipated technical conditions within the
      municipal bond market, we expect these bonds to continue to perform well
      and provide attractive income during the coming months.

      We added exposure to bonds with maturities at the long-term end of the
      yield curve, (i.e., 20 years or longer), in the RiverSource state
      tax-exempt funds of California, Massachusetts, New York and Ohio. Toward
      the end of the period, we extended all six of the RiverSource state
      tax-exempt funds' duration a bit to bring it toward a neutral position
      relative to its respective Lehman benchmark index. In anticipation of the
      Fed nearing an end of its current tightening cycle, we believed it would
      be appropriate to add some interest rate sensitivity to the Funds.

      We focused on further diversifying the portfolios by bond holding,
      maturity, coupon and call dates. We believe this disciplined approach to
      portfolio diversification -- across multiple parameters -- should help
      reduce the volatility and risks associated with interest rate movements
      and produce more consistent returns for the Funds over the long term. At
      the same time, we sought opportunities to carry out tactical strategies
      wherever and whenever possible.

QUESTIONS & ANSWERS

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

A:    Going forward, we believe the major factor affecting the municipal market
      may well be the unexpected slowdown in new issue supply seen during the
      first six months of 2006. We expect the slowdown to continue through much
      of the year. As a result, municipal bonds are expensive, but, as interest
      rates have risen, so, too, has retail buyer demand. Given this technical
      condition within the supply/demand balance of municipal bonds, we believe
      the tax-exempt bond market may well continue to outperform the taxable
      bond market through 2006.

      From a broader perspective, we intend to position the Funds based on our
      belief that U.S. interest rates across the range of maturities, or yield
      curve, have risen to levels that seem reasonable given our economic view.
      We believe the most likely scenario is for inflation to be nudged higher
      but also for a modest economic slowdown to become apparent toward the end
      of 2006, with a slowdown in the housing sector the likely catalyst. We
      thus believe the Fed may soon pause in its current tightening cycle.

      Given this view, we intend to maintain the Funds' current neutral duration
      positioning compared to their respective Lehman benchmark index for the
      near term. We further intend to reduce the Funds' exposure to insured
      bonds and increase their allocation to uninsured bonds, with a bias toward
      health care bonds, particularly bonds for large health care systems, and
      essential service revenue bonds, such as public power and water and sewer
      issues. We feel these sectors may enable the Funds to potentially pick up
      incremental yield without taking on significant risk. Finally, we are
      watching closely for opportunities to modestly increase the Funds'
      exposure to bonds rated BBB, including those in the tobacco and health
      care sectors.

      We intend to maintain our focus on seeking higher quality securities with
      good structure and on further diversifying the portfolios. Each Fund's
      emphasis continues to be on generating a high level of income generally
      exempt from federal income tax as well as from the respective state and
      local taxes.

THE FUND'S LONG-TERM PERFORMANCE

The chart on the facing page illustrates the total value of an assumed $10,000
investment in RiverSource California Tax-Exempt Fund Class A shares (from 7/1/96
to 6/30/06) as compared to the performance of three widely cited performance
indices, the Lehman Brothers California 2 Plus Year Municipal Bond Index, the
Lehman Brothers Municipal Bond Index, and the Lipper California Municipal Debt
Funds Index. In comparing the Fund's Class A shares to these indices, you should
take into account the fact that the Fund's performance reflects the maximum
sales charge of 4.75%, while such charges are not reflected in the performance
of the indices. Returns for the Fund include the reinvestment of any
distribution paid during each period.

NOTES TO FINANCIAL STATEMENTS

RiverSource State Tax-Exempt Funds

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

RiverSource California Tax-Exempt Trust (formerly AXP California Tax-Exempt
Trust) and RiverSource Special Tax-Exempt Series Trust (formerly AXP Special
Tax-Exempt Series Trust) were organized as Massachusetts business trusts.
RiverSource California Tax-Exempt Trust includes only RiverSource California
Tax-Exempt Fund. RiverSource Special Tax-Exempt Series Trust is a "series fund"
that is currently composed of individual state tax-exempt funds, including
RiverSource Massachusetts Tax-Exempt Fund, RiverSource Michigan Tax-Exempt Fund,
RiverSource Minnesota Tax-Exempt Fund, RiverSource New York Tax-Exempt Fund and
RiverSource Ohio Tax-Exempt Fund (the Funds). The Funds are non-diversified,
open-end management investment companies as defined in the Investment Company
Act of 1940 (as amended). Each Fund has unlimited authorized shares of
beneficial interest.

Each Fund's goal is to provide a high level of income generally exempt from
federal income tax as well as from the respective state and local income tax. A
portion of each Fund's assets may be invested in bonds whose interest is subject
to the alternative minimum tax computation. The Funds concentrate their
investments in a single state and therefore may have more credit risk related to
the economic conditions of the respective state than Funds that have a broader
geographical diversification.

Each Fund offers Class A, Class B and Class C shares.

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

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

o     Class C shares may be subject to a CDSC.

All classes of shares have identical voting, dividend and liquidation rights.
The distribution fee and transfer agency fees (class specific expenses) 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.

Each 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 sale 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.
Securities for which market quotations are not readily available are valued at
fair value according to methods selected in good faith by the Board. 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.

SECURITIES PURCHASED ON A FORWARD-COMMITMENT BASIS

Delivery and payment for securities that have been purchased by the Funds on a
forward-commitment basis, including when-issued securities and other
forward-commitments, can take place one month or more after the transaction
date. During this period, such securities are subject to market fluctuations,
and they may affect each Fund's net assets the same as owned securities. The
Funds designate cash or liquid securities at least equal to the amount of its
forward-commitments. At June 30, 2006, the Funds had no outstanding
forward-commitments.

OPTION TRANSACTIONS

To produce incremental earnings, protect gains and facilitate buying and selling
of securities for investments, the Funds 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 Funds
give up the opportunity for profit if the market price of the security
increases. The risk in writing a put option is that the Funds 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 Funds pay a premium whether or not the
option is exercised. The Funds also have the additional risk of being unable to
enter into a closing transaction if a liquid secondary market does not exist.
The Funds also may write over-the-counter options where completing the
obligation depends upon the credit standing of the other party.

Option contracts are valued daily at the closing prices on their primary
exchanges and unrealized appreciation or depreciation is recorded. The Funds
will realize a gain or loss when the option transaction expires or closes. When
options on debt securities or futures are exercised, the Funds will realize a
gain or loss. When other options are 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 the
premium received or paid.

FUTURES TRANSACTIONS

To gain exposure to or protect itself from market changes, the Funds may buy and
sell financial 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.


- --------------------------------------------------------------------------------
RIVERSOURCE STATE TAX-EXEMPT FUNDS - 2006 ANNUAL REPORT - 75
- --------------------------------------------------------------------------------



Upon entering into a futures contract, the Funds are 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 Funds 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 Funds recognize a realized gain or loss when the contract is closed
or expires.

SWAP TRANSACTIONS

To produce incremental earnings, to gain exposure to or protect itself from
market changes, the Funds may enter into swap agreements. Swaps are an agreement
between two parties to exchange periodic cash flows based on a specified amount
of principal. The net cash flow is generally the difference between a floating
market interest rate versus a fixed interest rate. The Funds may employ swaps to
synthetically add or subtract principal exposure to the municipal market.

Risks of entering into a swap include a lack of correlation between swaps and
the portfolio of municipal bonds the swaps are designed to hedge or replicate. A
lack of correlation may cause the swap to experience adverse changes in value
relative to expectations. In addition, swaps are subject to the risk of default
of a counterparty, and the risk of adverse movements in market interest rates
relative to the swap positions entered.

Swaps are valued daily and unrealized appreciation and depreciation is recorded.
The Funds will realize a gain or a loss when the swap is terminated. The Funds
did not enter into any swap agreements for the year ended June 30, 2006.

GUARANTEES AND INDEMNIFICATIONS

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

FEDERAL TAXES

Each 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. Each Fund is treated as a separate entity for federal
income tax purposes.

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

On the statement of assets and liabilities, as a result of permanent book-to-tax
differences, undistributed net investment income and accumulated net realized
gain (loss) have been increased (decreased), resulting in net reclassification
adjustments to additional paid-in capital by the following:

DIVIDENDS TO SHAREHOLDERS

Dividends from net investment income, declared daily and paid monthly, are
reinvested in additional shares of each Fund at net asset value or payable in
cash. Capital gains, when available, are distributed along with the last income
dividend of the calendar year.

OTHER

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

2. EXPENSES AND SALES CHARGES

Under an Investment Management Services Agreement, RiverSource Investments, LLC
(the Investment Manager) determines which securities will be purchased, held or
sold. Prior to Oct. 1, 2005, investment management services were provided by
Ameriprise Financial, Inc. (Ameriprise Financial). The management fee is a
percentage of each Fund's average daily net assets that declines from 0.41% to
0.25% annually as each Fund's assets increase. Prior March 1, 2006, the fee
percentage of each Fund's average daily net assets declined from 0.47% to 0.38%
annually as each Fund's assets increased.

Under the current Administrative Services Agreement, each Fund pays Ameriprise
Financial a fee for administration and accounting services at a percentage of
each Fund's average daily net assets that declines from 0.07% to 0.04% annually
as each Fund's assets increase. Prior to Oct. 1, 2005, the fee percentage of
each Fund's average daily net assets declined from 0.04% to 0.02% annually as
each Fund's assets increased. A minor portion of additional administrative
service expenses paid by the Funds are consultants' fees and fund office
expenses. Under this agreement, the Funds also pay taxes, audit and certain
legal fees, registration fees for shares, compensation of board members,
corporate filing fees and any other expenses properly payable by the Funds and
approved by the Board.

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 each Fund or other
RiverSource funds. Each Fund's liability for these amounts is adjusted for
market value changes and remains in each Fund until distributed in accordance
with the Plan.

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

o     Class A $20.50

o     Class B $21.50

o     Class C $21.00


- --------------------------------------------------------------------------------
80 - RIVERSOURCE STATE TAX-EXEMPT FUNDS - 2006 ANNUAL REPORT
- --------------------------------------------------------------------------------



The incremental transfer agency fee is the amount charged to the specific
classes for the additional expense above the base fee of $18.50.

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

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

For the year ended June 30, 2006, the Investment Manager and its affiliates
waived certain fees and expenses as follows:

5. BANK BORROWINGS

Each Fund has a revolving credit agreement with a syndicate of banks headed by
JPMorgan Chase Bank, N.A. (JPMCB), whereby each Fund may borrow for the
temporary funding of shareholder redemptions or for other temporary or emergency
purposes. The agreement went into effect Sept. 20, 2005. Each Fund must maintain
asset coverage for borrowings of at least 300%. The agreement, which enables
each Fund to participate with other RiverSource funds, permits borrowings up to
$500 million, collectively. Interest is charged to each Fund based on its
borrowings at a rate equal to either the higher of the Federal Funds Effective
Rate plus 0.40% or the JPMCB Prime Commercial Lending Rate. Borrowings are
payable within 60 days after such loan is executed. Each Fund also pays a
commitment fee equal to its pro rata share of the amount of the credit facility
at a rate of 0.07% per annum. Prior to this agreement, each Fund had a revolving
credit agreement that permitted borrowings up to $500 million with The Bank of
New York. Each Fund had no borrowings outstanding during the year ended June 30,
2006.

7. INFORMATION REGARDING PENDING AND SETTLED LEGAL PROCEEDINGS

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

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

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

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

There can be no assurance that these matters, or the adverse publicity
associated with them, will not result in increased fund redemptions, reduced
sale of fund shares or other adverse consequences to the Funds.

FUND EXPENSE EXAMPLES

(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, including management fees; distribution and service (12b-1) fees; and
other Fund expenses. These examples are intended to help you understand your
ongoing costs (in dollars) of investing in each Fund and to compare these costs
with the ongoing costs of investing in other mutual funds.

These examples are based on an investment of $1,000 invested at the beginning of
the period and held for the six months ended June 30, 2006.

ACTUAL EXPENSES

The first line of each 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 each table provides information about hypothetical account
values and hypothetical expenses based on each 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 each 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 each 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 each 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.

APPROVAL OF INVESTMENT MANAGEMENT SERVICES AGREEMENT

During the period covered by this report, RiverSource Investments, LLC
("RiverSource Investments" or the "investment manager"), a wholly-owned
subsidiary of Ameriprise Financial, Inc. ("Ameriprise Financial"), served as the
investment manager to RiverSource funds under an Investment Management Services
Agreement ("IMS Agreement").

The Board of Directors (the "Board") annually determines whether to continue the
IMS Agreement and subadvisory agreements, as applicable, by evaluating the
quality and level of services received and the costs associated with those
services. The Board did not make the specific determination this year as each
fund's IMS Agreement was approved by the vote of a majority of the outstanding
voting securities of the funds at a shareholder meeting held on Feb. 15, 2006.

PROXY VOTING

The policy of the Board is to vote all proxies of the companies in which the
Fund holds investments. The procedures are stated in the Statement of Additional
Information (SAI). You may obtain a copy of the SAI without charge by calling
