Important Notice

Supplement Dated June 23, 2017

to the currently effective Summary Prospectus, Statutory Prospectus and

Statement of Additional Information

for the Funds

The following information should be read in conjunction with the Prospectuses and Statement of Additional Information listed above for each Fund.

At the recommendation of WisdomTree Asset Management, Inc., each Fund’s investment adviser, after continued review of the product lineup and anticipated limited future prospects of investor demand for the Funds, among other considerations, the Board of Trustees voted to close and liquidate each Fund.

After the close of business on August 16, 2017, the Funds will no longer accept creation orders. The last day of secondary market trading of shares of each Fund will be August 16, 2017. Shareholders may sell Fund shares through a broker in the standard manner through this date. Customary brokerage charges may apply to such transactions. When a Fund commences liquidation of its portfolio, which is anticipated to occur on or around August 16, 2017, but may occur before August 16, 2017, and at different times for each Fund, each Fund will be increasing its cash holdings and deviating from the investment objective and strategies stated in its prospectus.

It is anticipated that shareholders remaining in the Funds after the last day of trading will have their shares redeemed automatically and will receive cash through their broker or other applicable financial intermediary on or around August 25, 2017, in an amount equal to the net asset value of their shares. This amount is expected to include any accrued capital gains and dividends. Shareholders remaining in a Fund and that receive cash will not be charged any transaction fees by the Fund. Whether you sell your shares or are automatically redeemed as described above, you will generally recognize a capital gain (or loss) equal to the amount you receive for your shares above (or below) your adjusted cost basis in such shares. Please consult your personal tax advisor about the potential tax consequences.
