1.	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.
2.	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 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 more than 60 days are valued at current market quotations. Short-term holdings maturing in 60 days or less are valued at current market quotations or amortized cost if the investment manager believes it approximates fair value.
	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 to offset the Cash Management Portfolio’s liability for deferred directors’ fees are valued at net asset values or, for closed-end funds, closing market prices.
