ProShares ETFs Cross $20 Billion in Assets After Two Years in Business

  
    
  
  
    
      ProShares announced today, two years after launching the nation's first 
      leveraged and first short exchange traded funds, that the firm's net 
      assets had exceeded $20 billion2. ProShares is 
      the fifth largest ETF provider in the country3 
      and the seventh largest in the world4. This 
      year, ProShares ranks second among all U.S. ETF families in net flows5.
    
    
      "We introduced 64 ETFs in two years, each the first of its kind," said 
      ProShares Chairman Michael Sapir. "Through ProShares, investors have, 
      for the first time, been able to seek profit when a part of the markets 
      drops, or hedge a portfolio simply by buying an ETF. They have also been 
      able to magnify their exposure to a variety of market indexes through 
      ProShares."
    
    
      ProShares launched its first ETFs on June 21, 2006, and now provides 
      investors with short and magnified investment exposure to a wide range 
      of market indexes. ProShares are benchmarked to domestic equity indexes 
      which include the S&P 500®, 
      NASDAQ-100, Russell 2000 and Dow Jones Sector Indexes, such as Oil & Gas 
      and Financials. Foreign equity indexes represented in the lineup include 
      MSCI EAFE, MSCI Emerging Markets and FTSE/Xinhua China 25. ProShares 
      recently introduced the first ETFs designed to provide short exposure to 
      Treasury securities, as represented by Lehman indexes.
    
    
      "Many successful investors have employed shorting and leveraged 
      investment techniques as part of their strategies," Sapir added. "We 
      have succeeded by providing investors with access to these techniques 
      through a simple-to-use vehicle, the ETF."
    
    
      About ProShares and ProFunds Group
    
    
      ProShares is part of the $28 billion ProFunds Group, the leader in short 
      and leveraged ETFs and mutual funds, managing approximately 85% of the 
      nation's short and leveraged fund assets6.

      ProFunds Group describes the portfolio managers common to ProFund 
      Advisors LLC, advisor to ProFunds mutual funds; and ProShare Advisors 
      LLC, advisor to ProShares ETFs.
    
    
      All investing involves risk, including the possible loss of principal. 
      Short ProShares should lose value when their market indexes rise, and 
      they entail certain risks, including, in some or all cases, aggressive 
      investment techniques, inverse correlation and market price variance 
      risks, all of which can increase volatility and decrease performance. 
      ProShares are not diversified investments. Narrowly focused investments, 
      including sector ETFs, typically exhibit higher volatility. ProShares 
      are designed to meet daily objectives; results over longer periods may 
      differ. There is no guarantee that any ProShares ETF will achieve its 
      investment objective.
