Example

This example is intended to help you compare the cost of investing in the International Equity Fund with the cost of investing in other mutual funds. The example assumes that you invest $10,000 in the International Equity Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the International Equity Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

One Year	Three Years	Five Years	Ten Years
$95	$652	$1,581	$3,966

Effective September 1, 2016, all additional references in the Fund’s Summary Prospectus, Prospectus and Statement of Additional Information to the expenses limitation are revised as indicated above.
