4 The MSCI Europe Index is a free float-adjusted market capitalization index that is designed to measure developed market equity performance in Europe. The term “free float” represents the portion of shares outstanding that are deemed to be available for purchase in the public equity markets by investors. The performance of the Index is listed in U.S. dollars and assumes reinvestment of net dividends. “Net dividends” reflects a reduction in dividends after taking into account withholding of taxes by certain foreign countries represented in the Index. It is not possible to invest directly in an index.
