In turn, the Master Growth Fund seeks to make shareholders investments grow by investing primarily in common stocks and seeking to invest in companies that appear to offer superior opportunities for growth of capital. The Master Growth Fund may invest up to 25% of its assets in common stocks and other securities outside the United States. The Master Growth Fund is designed for investors seeking capital appreciation principally through investment in stocks. Investors in the Portfolio should have a long-term perspective and be able to tolerate potentially sharp, short-term declines in value as the growth-oriented, equity-type securities generally purchased by the Master Growth Fund may involve large price swings and potential for loss. Capital Research and Management Company (Capital Research), the investment adviser of the Master Growth Fund, may consider environmental, social and governance (ESG) factors that, depending on the facts and circumstances, are material to the value of an issuer or instrument. ESG factors may include, but are not limited to, environmental issues (e.g., water use, emission levels, waste, environmental remediation), social issues (e.g., human capital, health and safety, changing customer behavior) or governance issues (e.g., board composition, executive compensation, shareholder dilution). Investment of the Portfolios assets in the Master Growth Fund is not a fundamental policy of the Portfolio and a shareholder vote is not required for the Portfolio to withdraw its entire investment in the Master Growth Fund.
