The Fund may not invest more than 20% of its total assets in unsecured high yield corporate bonds. The Fund invests primarily in senior floating rate loans of domestic and foreign borrowers (Senior Loans). The Fund secondarily invests in high yield, high risk corporate bonds. Senior Loans typically are secured with specific collateral and have a claim on the assets and/or stock of the borrower that is senior to subordinated debtholders and stockholders of the borrower. High yield corporate bonds are, and loans usually are of below investment grade quality and have below investment grade credit ratings, such ratings are associated with securities having high risk, speculative characteristics. The Fund may also invest in: other floating rate debt securities; fixed-income debt securities; preferred securities and other hybrid securities (which generally possess characteristics common to both equity and debt securities, many of which have fixed maturities); convertible securities; secured and unsecured subordinated loans, second lien loans and subordinated bridge loans (collectively, Junior Loans); and money market instruments. Other floating rate debt securities, fixed-income debt securities and money market instruments may include: bonds, notes and debentures issued by corporations; debt securities issued or guaranteed by the ?U.S. Government or one of its agencies or instrumentalities; and commercial paper. Senior Loans and Junior Loans are referred to together herein as loans. The Fund may invest up to 25% of its total assets in foreign Senior Loans, which must be denominated in ?U.S. dollars, euros, British pounds, Swiss francs, Canadian dollars, or Australian dollars, and foreign and emerging market securities, which are predominately U.S. dollar denominated. The Fund may engage in derivative transactions (such as futures contracts and options thereon, interest rate and credit default swaps, credit linked notes, forward foreign currency exchange contracts and other currency hedging strategies) to seek return, to hedge against fluctuations in securities prices, interest rates or currency exchange rates and/or as a substitute for the purchase or sale of securities or currencies. The Fund may enter into interest rate swaps for risk management purposes only. Except as required by applicable regulation, there is no stated limit on the Funds use of derivatives for such purposes. Preservation of capital is considered when consistent with the Funds investment objective. The Fund currently seeks to achieve its investment objective and strategies primarily by investing at least 65% of total assets in Eaton Vance Floating Rate Portfolio and not more than 20% of total assets in High Income Opportunities Portfolio, separate registered investment companies managed by Eaton Vance Management or its affiliate, (the Portfolios). References to the Funds investments include both investments held directly by the Fund and indirectly through the Portfolios in which the Fund invests. To determine the allocation of the Funds assets between the two Portfolios, the portfolio managers meet periodically and agree upon an appropriate allocation that is consistent with the Funds investment objective and policies and takes into consideration market and other factors. When deemed by the investment adviser to be relevant to its evaluation of creditworthiness and when applicable information is available, the investment adviser considers environmental, social and/or governance issues (referred to as ESG) which may impact the prospects of an issuer (or obligor) or financial performance of an obligation. When considered, one or more ESG issues are taken into account alongside other factors in the investment decision-making process and are not the sole determinant of whether an investment can be made or will remain in the Funds portfolio. The Fund is not appropriate for investors who cannot assume the greater risk of capital depreciation or loss inherent in seeking higher yields. Show less
