Fund Investment Overview	(2) Fund Investment Overview The Fund invests with a view to tracking the changes, whether positive or negative, in the level of the DBIQ Optimum Yield Precious Metals Index Excess Return™ (the “DBIQ-OY Precious Metals ER™”, or the “Index”) over time, plus the excess, if any, of the Fund’s interest income from its holdings of United States Treasury Obligations and other high credit quality short-term fixed income securities over the expenses of the Fund. The Index is intended to reflect the change in market value of the precious metals sector. The commodities comprising the Index are gold and silver (each an “Index Commodity”, and collectively, the “Index Commodities”). From January 3, 2007 (commencement of investment operations) to December 31, 2010, the Fund invested with a view to tracking the changes, whether positive or negative, in the level of the Deutsche Bank Liquid Commodity Index–Optimum Yield Precious Metals Excess Return™ (the “Interim Index”) over time, plus the excess, if any, of the Fund’s interest income from its holdings of United States Treasury Obligations and other high credit quality short-term fixed income securities over the expenses of the Fund. After December 31, 2010, the Fund commenced tracking the Index. The Fund’s Interim Index is identical to the Index except with respect to the following non-substantive changes: (i) name of Index, and (ii) inception date of Index for Commodity Futures Trading Commission (the “CFTC”) purposes. Except as provided in the immediately preceding sentence, all prior underlying formulae, data (e.g., closing levels, measure of volatility, all other numerical statistics and measures) and all other characteristics (e.g., Base Date, Index Sponsor, rolling, etc.) with respect to the Interim Index is identical to the Index. The CFTC and/or commodity exchanges, as applicable, impose position limits on market participants trading in certain commodities included in the Index. The Index is comprised of futures contracts on each of the Index Commodities that expire in a specific month and trade on a specific exchange (the “Index Contracts”). As disclosed in the Fund’s Prospectus, if the Managing Owner determines in its commercially reasonable judgment that it has become impracticable or inefficient for any reason for the Fund to gain full or partial exposure to any Index Commodity by investing in a specific Index Contract, the Fund may invest in (i) a futures contract referencing the particular Index Commodity other than the Index Contract or, in the alternative, invest in (ii) other futures contracts not based on the particular Index Commodity ((i) and (ii) collectively, the “Alternative Futures Contracts”) if, in the commercially reasonable judgment of the Managing Owner, such Alternative Futures Contracts tend to exhibit trading prices that correlate with such Index Commodity. The Fund also holds United States Treasury Obligations and other high credit quality short-term fixed income securities for deposit with the Fund’s Commodity Broker as margin. The Fund does not employ leverage. As of December 31, 2012 and December 31, 2011, the Fund had $354,256,954 (or 100%) and $454,297,809 (or 97.64%), respectively, of its holdings of cash and United States Treasury Obligations and unrealized appreciation/depreciation on futures contracts on deposit with its Commodity Broker. Of this, $18,351,850 (or 5.18%) and $42,518,250 (or 9.36%), respectively, of the Fund’s holdings of cash and United States Treasury Obligations are required to be deposited as margin in support of the Fund’s long futures positions.
