It normally invests 60 to 70% of its assets in a mix of US and foreign equity securities, and 30 to 40% in investment-grade fixed-income securities (those rated BBB or higher, including government and convertible bonds) including money market instruments and cash. When selecting equities, the Fund follows a value investing approach and principally invests in income-producing securities of companies in mature markets with market capitalizations greater than $5 billion. When selecting fixed-income securities, the Fund may utilize a blend of US government securities, US-dollar issues of foreign governments, and investment-grade corporate debt securities, as well as money market instruments, with the aim of managing portfolio volatility and liquidity. To reduce risk, the Fund follows a value investment style, favoring income- producing securities and those of larger, more seasoned companies. The Fund seeks to invest in issuers that the investment adviser believes demonstrate sustainable characteristics. The adviser considers issuers with sustainable characteristics to be those issuers that are more established, consistently profitable, financially strong, and with robust policies in the areas of the environment, social responsibility, and corporate governance. The adviser employs a fundamental research driven approach to security selection and portfolio construction. The advisers focus on sustainability considers financial and non-financial characteristics from diverse sources including regulatory filings, market data, and data supplied by third-party vendors. The adviser uses that information to identify issuers with strong balance sheets, capable management teams with a track record of success, good cash flow, prospects for sustainable above-average earnings growth, and to assess issuers business models, over the long term. The Funds investment adviser employs a sustainable rating system based on its own, as well as third-party, data to identify issuers believed to have lower sustainability risks. The use of third-party data does not include third-party environmental, social, or governance ("ESG") ratings or criteria established by third parties for third-party ratings. The advisers proprietary scoring system assesses how well a company performs relative to a blend of its industry, sector, and country peers. In addition to the financial considerations discussed above, the adviser considers sustainability practices such as carbon emissions, water usage, renewable energy, and fair labor and supply chain practices. The Funds sustainability evaluation process considers risks and opportunities holistically, meaning an issuer will not necessarily be excluded from investment due to any one particular factor if the overall analysis results in a favorable evaluation by the adviser. The adviser also uses negative screening to exclude companies primarily engaged in higher sustainability risk businesses such as alcohol, tobacco, pornography, weapons, gambling, and companies in the business of fossil fuel extraction, production, or refining. The Fund generally does not invest in any company with exposure to the foregoing businesses, but may invest in a company if the company is not primarily engaged in higher sustainability risk businesses or if, in the opinion of the adviser, sustainability risks are mitigated by other factors.
