The funds investment objective is to seek capital appreciation.
The fund invests primarily in foreign equity securities across developed and emerging markets, selected through bottom-up fundamental analysis by a team of sector leaders and research analysts; it may also use quantitative screening tools to evaluate issuers. The fund is managed to be sector neutral to the MSCI EAFE Index using the adviser's custom industry and sector classifications. Because the fund's active selection approach may diverge from the index's holdings, performance may differ from the MSCI EAFE Index.
