The convertible securities may be issued by corporations, or other non-governmental issuers similar to corporations; issued or guaranteed by governments or their subdivisions, agencies, authorities, instrumentalities or sponsored enterprises; or issued by a supranational organization.

The convertible securities may be issued by corporations, or other non-governmental issuers similar to corporations; issued or guaranteed by governments or their subdivisions, agencies, authorities, instrumentalities or sponsored enterprises; or issued by a supranational organization. The Investment Manager seeks to achieve the Portfolios investment objective primarily through actively managing a portfolio of convertible securities economically tied to the US. As part of its investment process, the Investment Manager undertakes the following analysis of the convertible securities in which the Portfolio may invest: proprietary quantitative analysis to assess each convertible securitys exposure or sensitivity to factors such as equity market performance, interest rates and credit spreads and its implied volatility, in order to assist the Investment Manager in forming a view regarding the relative value of the convertible security when assessed against: (i) comparable convertible securities; (ii) its historical price-to-book ratios (a measure of the securitys issuers market capitalization (or valuation) to its book value); (iii) the creditworthiness of the issuer; and/or (iv) what the Investment Manager assesses to be the future growth outlook or valuation prospects of the equity into which the security is convertible; credit analysis , which will look at the credit quality of the issuers of the convertible securities (i.e., the capacity of an issuer to meet its obligations), the potential for credit quality improvement, the duration of the convertible securities, etc.; and fundamental, bottom-up analysis of the equity securities into which the convertible securities are convertible in order to form a view as to the growth outlook for the issuer, and the potential for improving valuations, in the underlying equity securities. The Portfolio may invest without limitation in securities rated below investment grade (i.e., lower than Baa by Moodys Investors Service, Inc. (Moodys) or lower than BBB by S&P Global Ratings (S&P)) (junk bonds) or equivalent unrated securities as determined by the Investment Manager. Additionally, the Portfolio is not restricted to investments in securities of any particular maturity or duration, and there are no restrictions on the Portfolios average maturity or duration. Duration is an estimate of the sensitivity of the price of a fixed income or convertible security to a change in interest rates. Generally, the longer the duration, the higher the expected volatility. For example, the market price of a fixed income or convertible security with a duration of three years would be expected to decline 3% if interest rates rose 1%. Conversely, the market price of the same security would be expected to increase 3% if interest rates fell 1%. The Portfolio may invest up to 20% of its assets in securities and other assets which need not be convertible securities as described below and need not be economically tied to the US as described above, including securities of emerging markets issuers. Convertible securities are fixed-income and preferred equity securities that pay a fixed or floating rate of interest or dividends and that convert into: (1) underlying shares of common stock or other equity securities of the issuer of the convertible securities or of another issuer; (2) cash; or (3) a combination of cash and common stock or other equity securities of the issuer of the convertible securities or of another issuer; in each case, the form and amount of payment upon conversion is determined by the terms of the governing documents of the convertible securities. As a result, convertible securities have characteristics similar to both fixed-income and equity securities. The Portfolio may, but is not required to, (1) enter into interest rate, bond and equity index futures contracts and interest rate and credit default swap agreements; and (2) purchase put and call options on securities (including shares of exchange-traded open-end management investment companies (ETFs)) and indexes, in each case for hedging purposes or to seek to increase returns. Although the Portfolio is classified as diversified under the Investment Company Act of 1940, as amended (the 1940 Act), it may invest in a smaller number of issuers than other, more diversified investment portfolios. In addition, implementation of the Portfolios investment strategy may, during certain periods, result in the investment of a significant portion of the Portfolios assets in a particular market sector.
