Notes to Schedule of Investments

† The value of investments in equity securities and interest rate swap contracts by Neuberger Berman Real Estate Securities Income Fund Inc. (the “Fund”) is determined by Neuberger Berman Management LLC (“Management”) primarily by obtaining valuations from an independent pricing service based on the latest sale price when that price is readily available. Securities traded primarily on the NASDAQ Stock Market are normally valued by the Fund at the NASDAQ Official Closing Price ("NOCP") provided by NASDAQ each business day. The NOCP is the most recently reported price as of 4:00:02 p.m., Eastern time, unless that price is outside the range of the "inside" bid and asked prices (i.e., the bid and asked prices that dealers quote to each other when trading for their own accounts); in that case, NASDAQ will adjust the price to equal the inside bid or asked price, whichever is closer. Because of delays in reporting trades, the NOCP may not be based on the price of the last trade to occur before the market closes. If there is no reported sale of a security on a particular day, the independent pricing service may value the security based on reported market quotations.  Management has developed a process to periodically review information provided by independent pricing services. If a valuation is not available from an independent pricing service, the Fund seeks to obtain quotations from principal market makers. If such quotations are not readily available, securities are valued using methods the Board of Directors of the Fund (the “Board”) 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.  Foreign security prices are furnished by independent quotation services and expressed in local currency values. Foreign security prices are currently translated from the local currency into U.S. dollars using the exchange rate as of 4:00 p.m., Eastern time. The Board has approved the use of Interactive Data Pricing and Reference Data, Inc. (“Interactive”) to assist in determining the fair value of the Fund’s foreign equity securities when changes in the value of a certain index suggest that the closing prices on the foreign exchanges may no longer represent the amount that the Fund could expect to receive for those securities.  In this event, Interactive will provide adjusted prices for certain foreign equity securities using a statistical analysis of historical correlations of multiple factors. In the absence of precise information about the market values of these foreign securities as of the close of the New York Stock Exchange, the Board has determined on the basis of available data that prices adjusted in this way are likely to be closer to the prices the Fund could realize on a current sale than are the prices of those securities established at the close of the foreign markets in which the securities primarily trade. Fair value prices are necessarily estimates, and there is no assurance that such a price will be at or close to the price at which the security next trades.  Short-term debt securities with less than 60 days until maturity may be valued at cost, which, when combined with interest earned, is expected to approximate market value.

In accordance with Accounting Standards Codification (“ASC”) 820 “Fair Value Measurements and Disclosures” (“ASC 820”), formerly known as Financial Accounting Standards Board (“FASB”) Statement of Financial Accounting Standards No. 157, “Fair Value Measurements,” investments held by the Fund are carried at “fair value” as defined by ASC 820. Fair value is defined as the price that a fund would receive upon selling an investment in an orderly transaction to an independent buyer in the principal or most advantageous market for the investment under current market conditions. Various inputs, including the volume and level of activity for the asset or liability in the market are considered in determining the value of the Fund’s investments, some of which are discussed above. Significant management judgment may be necessary to estimate fair value in accordance with ASC 820.

In addition to defining fair value, ASC 820 established a three-tier hierarchy of inputs to establish a classification of fair value measurements for disclosure purposes. The three-tier hierarchy of inputs is 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, amortized cost, etc.)

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

For information on the Fund’s significant accounting policies, please refer to the Fund’s most recent shareholder reports.

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

The following is a summary, by category of Level, of inputs used to value the Fund’s investments as of January 31, 2010:

Item 2. Controls and Procedures.

(b) There were no significant changes in the Registrant’s internal controls over financial reporting (as defined in Rule 30a-3(d) under the 1940 Act) that occurred during the Registrant’s last fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Registrant’s internal control over financial reporting.
