The PowerShares DWA Emerging Markets Momentum Portfolio (Fund) is based on the Dorsey Wright® Emerging Markets Technical Leaders Index (DWA Emerging Markets Technical Leaders Index). The Fund will normally invest at least 90% of its total assets in securities of emerging economies within Dorsey Wright & Associates classification definition, as well as American depositary receipts (ADRs) and global depositary receipts (GDRs) based on securities in the Index. The Index includes approximately 100 companies from the NASDAQ Emerging Markets Index that possess powerful relative strength characteristics and are domiciled in emerging market countries including, but not limited to Brazil, Chile, China, India, Indonesia, Philippines, South Africa, Thailand and Turkey. The Index excludes US companies listed on a US stock exchange. The Index is computed using the net return, which withholds applicable taxes for non-resident investors. The Fund and the Index are rebalanced and reconstituted quarterly.
