The bar chart and the performance table shown below provide some indication of the risks of investing in the Fund by showing changes in its performance from year to year and by comparing the Fund’s performance to a broad-based securities index, the MSCI ACWI Investable Market Index (Net). In addition, the Fund compares its performance to a blended benchmark, as an additional benchmark, consisting of a 90% weighting in the MSCI USA Index (Gross) and a 10% weighting in the MSCI ACWI ex USA Index (Net). The Net performance figures of each index reflect no deductions for fees, expenses or income taxes, except foreign withholding taxes. For additional information about the indexes, please see the section entitled “Index Descriptions.”
Past performance (before and after taxes) does not necessarily predict future performance. Fund performance shown below reflects fees, waivers and/or expense reimbursements during such period and reinvestment of distributions, if any. Without waivers/reimbursements, performance would have been lower.
