[1] The MSCI All-Country World Ex USA Index is a free float-adjusted market capitalization index that is designed to measure developed and developing market equity performance, excluding the U.S. MSCI, Inc. publishes two versions of this Index reflecting the reinvestment of dividends using two different methodologies: gross dividends and net dividends. While both versions reflect reinvested dividends, they differ with respect to the manner in which taxes associated with dividend payments are treated. In calculating the gross dividends version, MSCI reinvests as much as possible of a company’s dividend distributions. The reinvested amount is equal to the total dividend amount distributed to persons residing in the country of the dividend-paying company. Gross total return indexes do not, however, include any tax credits. In calculating the net dividends version, MSCI incorporates reinvested dividends applying the withholding tax rate applicable to foreign non-resident institutional investors that do not benefit from double taxation treaties.
