[1] Fund expenses may have been partially absorbed by the investment adviser and its affiliates. Without these reductions, the fund’s returns may have been lower. Performance does not reflect the deduction of taxes that a shareholder would pay on fund distributions or on the redemption of fund shares.
[2] The fund’s performance relative to the index may be affected by fair-value pricing and timing differences in foreign exchange calculations.
[3] Due to new regulatory requirements, the fund’s regulatory index has changed from the FTSE EPRA Nareit Global Index (Net) to the MSCI ACWI Index (Net). The MSCI ACWI Index (Net) provides a broad measure of market performance. The FTSE EPRA Nareit Global Index (Net) is the fund’s additional index and is more representative of the fund’s investment universe than the regulatory index.
[4] The net version of the index reflects reinvested dividends net of withholding taxes but reflects no deductions for expenses or other taxes.
