Example
The example below is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.


The example assumes that you invest $10,000 in the Fund, your investment has a 5% return each year and the Fund's operating expenses remain the same (except that the example incorporates the fee waiver and/or expense reimbursement arrangement for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

As an essential and integrated part of the investment process, the Sub-Adviser seeks to engage with management teams to assess relevant factors material to long term sustainable returns including environmental, social and governance (ESG) factors.
