Lazard generally focuses on investing in securities of companies with a market capitalization of $3 billion or more. •LSV generally focuses on investing in securities of companies that it believes are undervalued in the marketplace at the time of purchase and show recent positive signals, such as an appreciation in price and increase in earnings. LSV uses a quantitative investment model to make investment decisions, ranking securities based on fundamental measures of value and indicators of near-term recovery.ECM maintains a strategic allocation of the Fund’s assets with each Sub-Adviser and reviews the asset allocations on a quarterly basis, or more frequently as deemed necessary. As of the date of this Prospectus, the target percentage is a 50% allocation of the Fund’s assets to Keyridge, a 25% allocation of the Fund’s assets to Lazard, and a 25% allocation of the Fund’s assets to LSV. Actual allocations may vary from the target allocations and ECM may change the asset allocations at any time without shareholder notice or approval.
