Management process. Portfolio management aims to add value through stock selection. In choosing securities, portfolio management employs a risk-balanced bottom-up selection process to identify companies it believes are well-positioned and that have above average and sustainable growth potential. Portfolio management utilizes a proprietary investment process designed to identify attractive investments by utilizing proprietary research conducted by in-house analysts. The investment process also takes into consideration various valuation metrics to assess the attractiveness of stocks and assists portfolio management in devising allocations among investable securities. All investment decisions are made within risk parameters set by portfolio management. Portfolio management may favor different types of securities from different industries and companies at different times. Portfolio management generally considers environmental, social and governance (ESG) factors that it believes to be financially material. Portfolio management will normally sell a stock when its price fully reflects portfolio managements estimate of its fundamental value, its fundamentals have deteriorated, other investments offer better opportunities or in the course of adjusting the funds exposure to a given sector. Securities lending. The fund may lend securities (up to one-third of total assets) to approved institutions, such as registered broker-dealers, pooled investment vehicles, banks and other financial institutions. In connection with such loans, the fund receives liquid collateral in an amount that is based on the type and value of the securities being lent, with riskier securities generally requiring higher levels of collateral.
