Under normal circumstances, the intended outcome of this approach is a portfolio typically consisting of between 30 and 50 growth companies with the potential to outperform the Fund’s benchmarks over the long term. The portfolio managers focus on company research and the long-term outlook of companies and industries. Ideas can come from a wide variety of sources, including, but not limited to, research trips, company meetings, and relationships with industry thought leaders and academic institutions. Stock ideas are normally researched to assess a range of factors, including: long-term growth potential, geographic and industry positioning, competitive advantage, management, financial strength and valuation. The Fund is a non-diversified fund, which means that it may invest a relatively large percentage of its assets in a small number of issuers, industries or sectors The Fund aims to hold securities for long periods (typically at least 5 years), which generally results in relatively low portfolio turnover and is in line with the portfolio managers’ long-term investment outlook. When assessing a company’s long-term growth prospects, the portfolio managers seek to identify and to incorporate a range of factors that are material to managing the Fund’s investment risks and maximizing capital appreciation. Such factors potentially include the environmental, social, and/or governance characteristics of the company, such as stewardship, sustainable business practices, and/or corporate culture.
