The Investment Adviser has agreed to reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and, indemnification, and extraordinary expenses) equal on an annualized basis to 0.004% of the Fund’s average daily net assets. This arrangement will remain in effect through at least April 28, 2018, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees.

The following replaces in its entirety the “Summary—Expense Example” section of the Institutional Shares Prospectus:

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. This Example does not reflect the fees and expenses associated with any variable annuity contract or variable life insurance policy that uses the Fund as an investment option. Had those fees and expenses been included, the costs shown below would be higher.

This Example assumes that you invest $10,000 in Institutional Shares of the Fund for the time periods indicated and then redeem all of your Institutional Shares at the end of those periods (except that the Example incorporates the expense limitation arrangement for only the first year). The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:



	1 Year		3 Years		5 Years		10 Years
Institutional Shares	$	18	$	73	$	134	$	311
