Index/Benchmark

MSCI EAFE Index

The Index (Bloomberg symbol: MXEA) includes 85% of free float-adjusted, market capitalization in each industry group in developed market countries, excluding the U.S. and Canada. As of September 30, 2011, the Index consisted of the following 22 developed market country indexes: Australia, Austria, Belgium, Denmark, Finland, France, Germany, Greece, Hong Kong, Ireland, Israel, Italy, Japan, the Netherlands, New Zealand, Norway, Portugal, Singapore, Spain, Sweden, Switzerland and the United Kingdom. It is not possible to invest directly in an index.

Because the level of the Index is not computed as of the close of the U.S. securities markets due to differences in trading hours between U.S. and foreign markets, correlation to the Index will be measured by comparing the daily change in the fund’s net asset value per share to the performance of one or more U.S. exchange-traded securities or instruments that reflect the values of the securities underlying the Index as of the close of the U.S. securities markets.
