ProShares Ultra Semiconductors (the Fund) seeks daily investment results that correspond to twice (200%) the daily performance of the Dow Jones U.S. Semiconductor Index (the Index). The Fund intends to invest at least 80% of its net assets, including any borrowings for investment purposes, under normal circumstances, to equity securities contained in the Index and/or financial instruments that, in combination, have similar economic characteristics. It also intends to invest assets not invested in financial instruments, in debt instruments and/or money market instruments. The Fund intends to concentrate its investments in a particular industry or group of industries to approximately the same extent as the Index is so concentrated. Because all of the securities included in the Index are issued by companies in the semiconductor industry group, the Fund will be concentrated approximately 100% in the semiconductor industry. ProShare Advisors LLC serves as the investment advisor to the Fund.
