PowerShares 1-30 Laddered Treasury Portfolio (the Fund) seeks investment results that correspond generally to the price and yield of an index called the Ryan/Mergent 1-30 Year Treasury Laddered Index (the Index). The Index measures the potential returns of the United States Treasury yield curve based on approximately 30 equally weighted United States Treasury issues with fixed coupons, scheduled to mature in a proportional, annual laddered structure. The portfolio does not participate in treasury bills, treasury inflation-protected securities (TIPS) or zero-coupon securities (STRIPS). Securities included in the Index are selected by Mergent, Inc., ALM Research Solutions, LLC and Ryan Holdings, LLC (collectively, Ryan/Mergent or the Index Provider). The Fund will normally invest at least 80% of its total assets in the United States Treasury securities. The Fund’s investment advisor is Invesco PowerShares Capital Management LLC.
