the fund seeks to track changes , whether positive or negative , in the level of the dbiq optimum yield precious metals index excess return ( the “ index ” ) over time , plus the excess , if any , of the sum of the fund 's interest income from its holdings of united states treasury obligations ( “ treasury income ” ) , dividends from its holdings in money market mutual funds ( affiliated or otherwise ) ( “ money market income ” ) and dividends or distributions of capital gains from its holdings of t-bill etfs ( as defined below ) ( “ t-bill etf income ” ) over the expenses of the fund . the fund invests in futures contracts in an attempt to track its index . 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 ” ) . the fund may invest directly in united states treasury obligations . the fund may also gain exposure to united states treasury obligations through investments in exchange-traded funds ( “ etfs ” ) ( affiliated or otherwise ) that track indexes that measure the performance of united states treasury obligations with a maximum remaining maturity of up to 12 months ( “ t-bill etfs ” ) . the fund holds as collateral united states treasury obligations , money market mutual funds and t-bill etfs ( affiliated or otherwise ) , if any , for margin and or cash management purposes . while the fund 's performance will reflect the appreciation or depreciation of those holdings , the fund 's performance , whether positive or negative , will be driven primarily by its strategy of trading futures contracts with the aim of seeking to track the index . the fund pursues its investment objective by investing in a portfolio of exchange-traded commodity futures contracts that expire in a specific month and trade on a specific exchange ( the “ index contracts ” ) in the index commodities . the notional amounts of each index commodity included in the index are broadly in proportion to historic levels of the world 's production and stocks of the index commodities . the fund also holds united states treasury obligations and t-bill etfs , if any , for deposit with morgan stanley & co. llc , the fund 's commodity broker ( the “ commodity broker ” ) as margin , to the extent permissible under cftc rules and united states treasury obligations , cash , money market mutual funds and t-bill etfs ( affiliated or otherwise ) , if any , on deposit with the bank of new york mellon ( the “ custodian ” ) , for cash management purposes . the aggregate notional value of the commodity futures contracts owned by the fund is expected to approximate the aggregate net asset value ( “ nav ” ) of the fund , as opposed to the aggregate index value . the cftc and certain futures exchanges impose position limits on futures contracts , including on index contracts . as the fund approaches or reaches position limits with respect to an index commodity , the fund may commence investing in index contracts that reference other index commodities . in those circumstances , the fund may also trade in futures contracts based on commodities other than index commodities that the managing owner reasonably believes tend to exhibit trading prices that correlate with an index contract . the managing owner may determine to invest in other futures contracts if at any time it is impractical or inefficient to gain full or partial exposure to an index commodity through the use of index contracts . these other futures contracts may or may not be based on an index commodity . when they are not , the managing owner may seek to select futures contracts that it reasonably believes tend to exhibit trading prices that correlate with an index contract . the shares are intended to provide investment results that generally correspond to the changes , positive or negative , in the levels of the index over time . the value of the shares is expected to fluctuate in relation to changes in the value of the fund 's portfolio . the market price of the shares may not be identical to the nav per share , but these two valuations are expected to be very close . margin calls 22 “ initial ” or “ original ” margin is the minimum amount of funds that must be deposited by a futures trader with his commodity broker in order to initiate futures trading or to maintain an open position in futures contracts . “ maintenance ” margin is the amount ( generally less than initial margin ) to which a trader 's account may decline before he must deliver additional margin . a margin deposit is like a cash performance bond . it helps assure the futures trader 's performance of the futures contract that the trader purchases or sells . futures contracts are customarily bought and sold on margin that represents a very small percentage ( ranging upward from less than 2 % ) of the purchase price of the underlying commodity being traded . because of such low margins , price fluctuations occurring in the futures markets may create profits and losses that are greater , in relation to the amount invested , than are customary in other forms of investments . story_separator_special_tag rising commodity futures contracts prices for gold and silver futures contracts during the year ended december
