The Fund may invest in certain restricted securities, such as securities that are only eligible for resale pursuant to Rule 144A, and securities of U.S. and non-U.S. issuers that are issued pursuant to Regulation S.As part of the portfolio construction process, Wellington Management combines its top-down strategy with its bottom-up fundamental research. As part of this process, Wellington Management focuses on risk management; analysis of the business cycle; and sector and quality positioning.

The Fund may invest up to 15% of its net assets in preferred stocks, convertible securities, and securities accompanied by warrants to purchase equity securities.
