Seligman Portfolios, Inc.

Notes to Schedules of Investments (unaudited)

March 31, 2008

Organization – Seligman Portfolios, Inc. (the “Fund”) is registered with the Securities and Exchange Commission under the Investment Company Act of 1940, as amended (the “1940 Act”) as an open-end diversified management investment company consisting of nine separate portfolios (the “Portfolios”): Seligman Capital Portfolio (“Capital Portfolio”), Seligman Cash Management Portfolio (“Cash Management Portfolio”), Seligman Common Stock Portfolio (“Common Stock Portfolio”), Seligman Communications and Information Portfolio (“Communications and Information Portfolio”), Seligman Global Technology Portfolio (“Global Technology Portfolio”), Seligman International Growth Portfolio (“International Growth Portfolio”), Seligman Investment Grade Fixed Income Portfolio (“Investment Grade Portfolio”), Seligman Large-Cap Value Portfolio (“Large-Cap Value Portfolio”), and Seligman Smaller-Cap Value Portfolio (“Smaller-Cap Value Portfolio”), each designed to meet different investment goals. Shares of the Fund are provided as an investment medium for variable annuity and life insurance separate accounts offered by various insurance companies. Class 2 shares of the Communications and Information Portfolio are also offered to qualified pension or retirement plans.

Security Valuation – Net asset value per share is calculated as of the close of business of the New York Stock Exchange (“NYSE”), normally 4:00 p.m. Eastern time. Securities traded on an exchange are valued at the last sales price on the primary exchange or market on which they are traded. Fixed income securities not listed on an exchange or security market are valued by independent pricing services based on bid prices which consider such factors as coupons, maturities, credit ratings, liquidity, specific terms and features, and the US Treasury yield curve, or are valued by J. & W. Seligman & Co. Incorporated, the Fund’s investment manager, based on quotations provided by primary market makers in such securities. Equity securities not listed on an exchange or security market, or equity securities for which there are no last sales price, are valued at the mean of the most recent bid and asked prices or are valued by the investment manager based on quotations provided by primary market makers in such securities. Notwithstanding these valuation methods, the Global Technology Portfolio and International Growth Portfolio may adjust the value of securities as described below in order to reflect the fair value of such securities.

Many securities markets and exchanges outside the US close prior to the close of the NYSE; therefore, the closing prices for securities in such markets or on such exchanges may not fully reflect events that occur after the local market close but before the close of the NYSE. The Fund’s Board of Directors (the “Board”) approved fair value procedures under which a third-party pricing service on a regular basis recommends adjustments to the local closing prices of certain foreign equity securities. The adjustments are based on a statistical analysis of the historical relationship between the price movements of a security and independent variables such as US market movements, sector movements, movements in the ADR of a security (if any), and movements in country or regional exchange-traded funds or futures contracts. The factors used vary with each security, depending on which factors have been most important historically.

Other securities for which market quotations are not readily available (or are otherwise no longer valid or reliable) are valued at fair value determined in accordance with procedures approved by the Board. This can occur in the event of, among other things, natural disasters, acts of terrorism, market disruptions, intra-day trading halts and extreme market volatility. The determination of fair value involves subjective judgments. As a result, using fair value to price a security may result in a price materially different from the prices used by other mutual funds to determine net asset value or the price that may be realized upon the actual sale of the security.

Short-term holdings that mature in 60 days or less are valued at current market quotations or amortized cost if the investment manager believes it approximates fair value. Short-term holdings that mature in more than 60 days are valued as current market quotations until the 60th day prior to maturity and are then valued as described above for securities maturing in 60 days or less.

Investments held by the Cash Management Portfolio are generally valued using the amortized cost method which approximates fair value. Investments in certain other funds in the Seligman Group of Investment Companies purchased by the Cash Management Portfolio to offset its liability for deferred directors’ fees are valued at net asset values or, for closed-end funds, closing market prices.

Fair Value Measurement – On January 1, 2008, the Fund adopted Statement of Financial Accounting Standards No. 157 (“SFAS 157”), “Fair Value Measurements.” SFAS 157 establishes a three-tier hierarchy to classify the assumptions, referred to as inputs, used in valuation techniques (See note 2 above) to measure fair value of the Portfolios’ investments, other financial instruments and certain liabilities. These inputs are summarized in three broad levels: Level 1 – quoted prices in active markets for identical investments, financial instruments or liabilities; Level 2 – other significant observable inputs (including quoted prices in inactive markets or for similar investments, financial instruments or liabilities, interest rates, prepayment speeds, credit risk, etc.); and Level 3 – significant unobservable inputs (including the Portfolios’ own assumptions in determining fair value). The inputs or methodology used for valuing securities may not be an indication of the risk associated with investing in those securities.

The following is a summary of the value of the Portfolios’ investments, other financial instruments and liabilities as of March 31, 2008 based on the level of inputs used:

Risk – The following risks apply to some or all of the Portfolios. A Portfolio may concentrate its investments in stocks of large-, medium- or small-capitalization companies. At times, one or more of these groups of stocks has experienced periods of volatility and negative performance. During such periods, the value of such stocks may decline and the performance of a Portfolio investing in such companies may be negatively affected. The products of technology companies may be subject to severe competition and rapid obsolescence, and technology stocks may be subject to greater price fluctuation, government regulation, and limited liquidity as compared to other investments. To the extent that a Portfolio invests a substantial percentage of its assets in an industry, the Portfolio’s performance may be negatively affected if that industry falls out of favor. A portfolio with fewer holdings may be subject to greater volatility than a portfolio with a greater number of holdings. There are specific risks associated with global investing, such as currency fluctuations, foreign taxation, differences in financial reporting practices, and rapid changes in political and economic condition. US Government and fixed income securities are subject to interest rate risk, credit risk, prepayment risk and market risk. Securities that are not guaranteed by the US Government may have increased credit risk, including, but not limited to, the risk of non-payment of principal or interest. A Portfolio may invest a significant portion of its assets in securities of issuers that hold mortgage- and asset-backed securities and direct investments in securities backed by commercial and residential mortgage loans and other financial assets. Continuing shifts in the market’s perception of credit quality on securities backed by commercial and residential mortgage loans and other financial assets may result in increased volatility of market prices and periods of illiquidity that can negatively impact the valuation of certain issues held by such Portfolio. The value and related income of these securities are sensitive to changes in economic conditions, including delinquencies and/or defaults.
