Schedule of Investments October 31, 2008 (Unaudited)

(q)      Investments in companies considered to be an affiliate of the Fund, for purposes of Section 2(a)(3) of the Investment Company Act of 1940, were as follows:
 
     Affiliate    Net Activity       Income 
     CMA New York Municipal Money Fund         35,127,857    $ 79,099 
(r) Represents the current yield as of report date.         

  		• Effective August 1, 2008, the Fund adopted Financial Accounting Standards Board Statement of Financial Accounting Standards No. 157, "Fair Value Measurements" ("FAS 157"). FAS 157 clarifies the definition of fair value, establishes a framework for measuring fair values and requires additional disclosures about the use of fair value measurements. Various inputs are used in determining the fair value of investments, which are as follows:
     
     
  		• Level 1 - price quotations in active markets/exchanges for identical securities
     
     
  		• Level 2 - other observable inputs (including, but not limited to: quoted prices for similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the assets or liabilities (such as interest rates, yield curves, volatilities, prepayment speeds, loss severities, credit risks, and default rates) or other market-corroborated inputs)
     
     
  		• Level 3 - unobservable inputs based on the best information available in the circumstance, to the extent observable inputs are not available (including the Fund's own assumption used 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. For information about the Fund's policy regarding valuation of investments and other significant accounting policies, please refer to the Fund's most recent financial statements as contained in its annual report.
     
      The following table summarizes the inputs used as of October 31, 2008 in determining the fair valuation of the Fund's investments:
     
    Valuation    Investments in 
    Inputs    Securities 
    Level 1    $ 49,099,024 
    Level 2    699,554,600
