NOTES TO PORTFOLIO OF INVESTMENTS (a) Securities are valued by using procedures described in Note 1 to the financial statements in the most recent Semiannual Report dated Jan. 31, 2008. (b) Interest rate varies either based on a predetermined schedule or to reflect current market conditions; rate shown is the effective rate on April 30, 2008. The maturity date disclosed represents the final maturity. For purposes of Rule 2a-7, maturity is the later of the next put or interest rate reset date. (c) Commercial paper sold within terms of a private placement memorandum, exempt from registration under Section 4(2) of the Securities Act of 1933, as amended, and may be sold only to dealers in that program or other "accredited investors." This security has been determined to be liquid under guidelines established by the Fund's Board of Directors. These securities may be resold in transactions exempt from registration, normally to qualified institutional buyers. At April 30, 2008, the value of these securities amounted to $1,107,719,925 or 21.0% of net assets. (d) Denotes investments in structured investment vehicles ("SIVs"). SIVs have 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. As of April 30, 2008, the Fund had three SIVs which remain outstanding with an aggregate value of $133.7 million, representing 2.5% of net assets. The three remaining SIV holdings are Cheyne Finance (Cheyne), WhistleJacket Capital LLC (WJC) and Sigma Finance. These investments were in the most senior debt issued by these vehicles. Subsequent to April 30, 2008, the Fund's $40 million remaining position in Sigma Finance matured on June 6, 2008 and all interest and principal payments were received. - -------------------------------------------------------------------------------- 2 RIVERSOURCE CASH MANAGEMENT FUND -- PORTFOLIO OF INVESTMENTS AT APRIL 30, 2008 NOTES TO PORTFOLIO OF INVESTMENTS (CONTINUED) During the period, the Fund's holdings in the following SIVs matured and all interest and principal payments were received on a timely basis:

On Aug. 28, 2007, Cheyne breached a financial covenant relating to the market value of its underlying collateral, resulting in the occurrence of an "enforcement event." This led to the appointment of receivers on Sept. 4, 2007. On Oct. 17, 2007, the receivers declared Cheyne to be insolvent. On Apr. 17, 2008, the Fund received a payment from Cheyne of $4.3 million, reducing the outstanding principal from $23.0 million to $18.7 million. However, Cheyne remains in default as of its Nov. 12, 2007 maturity date. The receivers are currently developing a restructuring plan which will likely result in the Fund receiving less than full payment on its investment. Accordingly, this holding has been determined to be illiquid. On Feb. 11, 2008, WJC breached a financial covenant 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 two positions in WJC are in default as of their respective maturity dates, Feb. 25, 2008 ($35 million) and March 20, 2008 ($40 million). The receivers are currently developing a restructuring plan which may result in the Fund receiving less than full payment on its investment. This holding has been determined to be illiquid. Pursuant to the Fund's pricing procedures, securities are valued utilizing the amortized cost method permitted in accordance with Rule 2a-7 under the Investment Company Act of 1940. Rule 2a-7 also requires periodic monitoring ("Shadow Pricing Procedure") of the deviation between the net asset value per share of the Fund using the amortized cost method and the market value based net asset value to ensure that the amortized cost method continues to provide an appropriate net asset value for the Fund. As of April 30, 2008, the Fund valued Cheyne and WJC at amortized costs of $18.7 million and $75.0 million, respectively. For purposes of the 2a-7 monitoring procedure described above, Cheyne and WJC were fair valued at $12.9 million and $71.8 million, respectively. As of June 17, 2008 the remaining position of Cheyne has been fair valued at $12.5 million and WJC has been fair valued at $72.1 million for the market value inputs into the Shadow Pricing Procedure. For the fiscal quarter ended April 30, 2008 and through June 17, 2008 all investments held by the Fund, including SIVs, were valued at amortized cost in compliance with 2a-7 procedures. In addition, for the same time periods the deviations resulting from the Shadow Pricing Procedure were not material to the Fund's $1 net asset value. (e) Identifies issues considered to be illiquid as to their marketability. These securities may be valued at fair value according to procedures approved, in good faith, by the Fund's Board of Directors. Information concerning such security holdings at April 30, 2008, is as follows:
