Effective on or about March 18, 2013, Market Vectors Solar Energy ETF (NYSE Arca: KWT) will begin tracking the Market Vectors ® Global Solar Energy Index (MVKWTTR). MVKWTTR uses the Market Vectors index methodology that focuses on investability, diversification and pure-play exposure to the relative asset class. This methodology is shared by the benchmark indexes of several other Market Vector ETFs, including Brazil Small-Cap (BRF ®), Indonesia (IDX), Junior Gold Miners (GDXJ ®), Oil Services (OIH), Russia (RSX ®), Semiconductor (SMH) and Vietnam (VNM). MVKWTTR is a rules based, modified capitalization-weighted, float-adjusted index that seeks to track the performance of the global solar energy segment. Similar to other Market Vectors indices, MVKWTTR is built specifically for ETFs. The Index employs constituent weighting caps that will help diversify the ETF among more names in the global solar energy segment, while extensive liquidity screens are used to enhance the tradability of the ETF. Additionally, to create an index representative of the industry, its rules require that constituents generate at least fifty percent of their revenues from the global solar energy segment. The constituent names and weights of every Market Vectors index, including MVKWTTR, are provided daily on the Market Vectors Index Solutions website: www.marketvectorsindices.com. MVMKWTTR was developed, and is published by Market Vectors Index Solutions GmbH (MVIS), a Germany-based wholly owned subsidiary of Van Eck Associates Corporation. MVIS develops, markets and licenses Market Vectors branded indexes. In total, approximately $8.7 billion in assets under management are linked to exchange-traded products using Market Vectors indexes, as of September 30, 2012.
