*	Non-income producing security.

§	Security or portion thereof is out on loan.
§§	Represents security purchased with cash collateral received for securities on loan.

Security Valuation – The net asset value of the Fund is determined daily as of the close of regular trading on the New York Stock Exchange, Inc. (the "Exchange") on each day the Exchange is open for business. The Fund's equity investments are valued at market value, which is generally determined using the closing price on the exchange or market on which the security is primarily traded at the time of valuation (the "Valuation Time").  If no sales are reported, equity investments are generally valued at the most recent bid quotation as of the Valuation Time or at the lowest asked quotation in the case of a short sale of securities. Debt securities with a remaining maturity greater than 60 days are valued in accordance with the price supplied by a pricing service, which may use a matrix, formula or other objective method that takes into consideration market indices, yield curves and other specific adjustments. Debt obligations that will mature in 60 days or less are valued on the basis of amortized cost, which approximates market value, unless it is determined that using this method would not represent fair value. Investments in mutual funds are valued at the mutual fund’s closing net asset value per share on the day of valuation. Securities and other assets for which market quotations are not readily available, or whose values have been materially affected by events occurring before the Fund’s Valuation Time but after the close of the securities’ primary markets, are valued at fair value as determined in good faith by, or under the direction of, the Board of Trustees under procedures established by the Board of Trustees. The Fund may utilize a service provided by an independent third party which has been approved by the Board of Trustees to fair value certain securities. When fair-value pricing is employed, the price of securities used by a fund to calculate its net asset value may differ from quoted or published prices for the same securities.

Federal Income Tax Cost – At January 31, 2006, the identified cost for federal income tax purposes, as well as the gross unrealized appreciation from investments for those securities having an excess of value over cost, gross unrealized depreciation from investments for those securities having an excess of cost over value and the net unrealized appreciation from investments were $245,739,617, $68,153,670, $(4,286,032) and $63,867,638, respectively.

Other information regarding the Fund is available in the Fund’s most recent Report to Shareholders. This information is also available on the Fund’s website at www.credit-suisse.com/us as well as on the website of the Securities and Exchange Commission – http://www.sec.gov.
