Certain risks associated with investment in the WisdomTree International Dividend ex-Financials Fund, as noted in the “Primary Investment Risks” section of the Fund’s Prospectus, are hereby replaced with the following disclosure:

 

n

Geographic Concentration Risk. To the extent the Fund invests a significant portion of its assets in the securities of companies of a single country or region it is more likely to be impacted by events or conditions affecting that country or region. For example, political and economic conditions and changes in regulatory, tax, or economic policy in a country could significantly affect the market in that country and in surrounding or related countries and have a negative impact on a Fund’s performance. The Fund generally invests a relatively large percentage of its assets in companies organized in Britain, France and Italy.

 

n

Telecommunication Investing. The Fund generally invests a relatively large percentage of its assets in the telecommunication industry. The telecommunication industry can be significantly affected by, among other things, government intervention and regulation, the need for companies to commit substantial capital to meet increasing competition, particularly in formulating new products and services using new technology, and technological innovations that may make the products and services of telecommunications companies obsolete.

 

n

Utilities Investing. The Fund generally invests a relatively large percentage of its assets in the utilities sector. The utilities sector can be significantly affected by, among other things, demand for services, government regulation, commodity prices and interest rate sensitivity.
