Fund Description: ProShares Large Cap Core Plus, formerly ProShares Credit Suisse 130/30 ETF is an exchange-traded index fund or Index ETF which is a separate investment portfolio of the ProShares Trust, an investment management company. INVESTMENT OBJECTIVE: ProShares Large Cap Core Plus, formerly ProShares Credit Suisse 130/30 ETF seeks investment results, before fees and expenses, that track the performance of the Credit Suisse 130/30 Large Cap Index. INDEX DESCRIPTION: The Credit Suisse 130/30 Large Cap Index is designed to replicate an investment strategy that establishes either long or short positions in the stocks of certain of the 500 largest U.S. companies based on market capitalization (the Universe) by applying a rules-based ranking and weighting methodology. The design intends to provide an indexed representation of a quantitatively constructed 130/30 U.S. large cap equity strategy. This results in the Index having total long exposure of 130% and total short exposure of 30% at each monthly reconstitution date. The Index will have risk characteristics similar to the Universe and will generally rise and fall with the Universe, with the goal, but not the guarantee, of incremental risk-adjusted outperformance as compared to the Universe. As of June 30, 2009, the Index contained 268 long and 129 short positions. The Index is published under the Bloomberg ticker symbol CS13030S. The long portion (i.e., +130) of the Index is published under the Bloomberg ticker symbol CS130L and the short portion (i.e. -30) of the Index is published separately under the Bloomberg ticker symbol CS130S. FUND STRATEGY: The Fund invests in a combination of equity securities and derivatives that ProShare Advisors believes should track the performance of the Index. Assets of the Fund not invested in equity securities or derivatives will typically be held in money market instruments. In seeking to achieve each Fund’s investment objective, a mathematical approach to investing is used which determines the type, quantity and mix of investment positions that a Fund should hold to approximate the performance of the Index. A sampling process involves selecting a representative sample of securities in an index principally to enhance liquidity and reduce transaction costs while seeking to maintain high correlation with, and similar aggregate characteristics to, the Index. At the close of the markets each trading day, the Fund will seek to position its portfolio so that the Fund’s exposure to the Index is consistent with the Fund’s investment objective. The impact of the Index’s movements during the day will determine whether the Fund’s portfolio needs to be re-positioned. FUND MANAGEMENT: ProShare Advisors serves as the investment advisor and provides investment advice and management services to the Fund.
