Van Kampen Money Market Fund
Portfolio of Investments ■ February 28, 2009 (Unaudited) continued

     The Fund adopted Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157, “Fair Value Measurements” (''FAS 157’’), effective June 1, 2008. In accordance with FAS 157, fair value is defined as the price that the Fund would receive to sell an investment or pay to transfer a liability in an orderly transaction with an independent buyer in the principal market, or in the absence of a principal market the most advantageous market for the investment or liability. FAS 157 establishes a three-tier hierarchy to distinguish between (1) inputs that reflect the assumptions market participants would use in pricing an asset or liability developed based on market data obtained from sources independent of the reporting entity (observable inputs) and (2) inputs that reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing an asset or liability developed based on the best information available in the circumstances (unobservable inputs) and to establish classification of fair value measurements for disclosure purposes. Various inputs are used in determining the value of the Fund’s investments. The inputs are summarized in the three broad levels listed below.

Level 1—quoted prices in active markets for identical investments

Level 2—other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risk, etc.)

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

     The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

     The following is a summary of the inputs used as of February 28, 2009 in valuing the Fund’s investments carried at value:

	Investments in
Valuation Inputs	Securities
Level 1 — Quoted Prices	$	-0-
Level 2 — Other Significant Observable Inputs		899,417,249
Level 3 — Significant Unobservable Inputs		-0-
Total	$	899,417,249

Security Valuation Investments are valued at amortized cost, which approximates market value. Under this valuation method, a portfolio instrument is initially recorded at cost, any discount is accreted and any premium is amortized on a straight-line basis to the maturity of the instrument.

Item 2. Controls and Procedures.

(a) The Fund’s principal executive officer and principal financial officer have concluded that the Fund’s disclosure controls and procedures are sufficient to ensure that information required to be disclosed by the Fund in this Form N-Q was recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, based upon such officers’ evaluation of these controls and procedures as of a date within 90 days of the filing date of the report.

(b) There were no changes in the Fund’s internal control over financial reporting that occurred during the registrant’s fiscal quarter that has materially affected, or is reasonably likely to materially affect, the Fund’s internal control over financial reporting.

Item 3. Exhibits.

(a) A certification for the Principal Executive Officer of the registrant is attached hereto as part of EX-99.cert.

(b) A certification for the Principal Financial Officer of the registrant is attached hereto as part of EX-99.cert.
