For all other debt securities requiring daily quotations, bid price quotations are obtained from principal market makers in those securities. The Fund values all other securities, including securities for which the necessary last sale, asked and/or bid prices are not readily available, by methods the Board of Trustees has approved on the belief that they reflect fair value. Numerous factors may be considered when determining the fair value of a security, including available analyst, media or other reports, trading in futures or ADRs and whether the issuer of the security being fair valued has other securities outstanding. Fair value prices are necessarily estimates, and there is no assurance that such prices will be at or close to the price at which the security is next quoted. Securities with remaining maturities of 60 days or less are valued at amortized cost. This method involves valuing a portfolio security initially at its cost and thereafter assumes a constant amortization to maturity of any discount of premium. (#) At cost, which approximates market value. (##) At September 30, 2007, the cost of investments for U.S. federal income tax purposes was $263,878,231. Gross unrealized appreciation of investments was $3,047,560 and gross unrealized depreciation of investments was $4,685,800, resulting in net unrealized depreciation of $1,638,240, based on cost for U.S. federal income tax purposes. (@) Neuberger Berman Prime Money Fund ("Prime Money") is also managed by Neuberger Berman Management Inc. and may be considered an affiliate since it has the same officers, Board members, and investment manager as the Fund and because, at times, the Fund may own 5% or more of the outstanding voting securities of Prime Money. (n) Restricted security subject to restrictions on resale under federal securities laws. These securities may be resold in transactions exempt from registration, normally to qualified institutional buyers under Rule 144A under the Securities Act of 1933, as amended, and have been deemed by the investment manager to be liquid. At September 30, 2007, these securities amounted to approximately $60,464,295 or 34.2% of net assets applicable to common shareholders. (^^) Denotes a step-up bond: a zero coupon bond that converts to a fixed rate of interest at a designated future date. (O) All or a portion of this security was purchased on a when-issued basis.
