The Shares of each Fund are designed to reflect as closely as possible the changes, positive or negative, in the level of its corresponding Index, over time, through its portfolio of exchange traded futures contracts on its Index Commodities. The value of the Shares of each Fund relates directly to the value of its portfolio, less the liabilities (including estimated accrued but unpaid expenses) of the Fund. The price of the various Index Commodities may fluctuate widely. Several factors may affect the prices of the Index Commodities, including, but not limited to:

The following two paragraphs apply only to PowerShares DB Precious Metals Fund, or the DBP Fund.

Effective as of August 15, 2014, the daily London silver fix, or the London Silver Fix, which has served as a global benchmark, will be replaced by an electronic silver benchmark operated by the CME Group and Thomson Reuters, or the Replacement Silver Fix. The CME Group will provide the pricing and Thomson Reuters will provide the administration and the governance for the Replacement Silver Fix.

As of the date of this Prospectus, the DBP Fund invests in silver futures contracts that trade on the CME. According to the rules associated with these silver futures contracts, the silver that underlies these futures contracts must be silver that is produced by a list of specific producers. To the extent that these approved producers rely upon the Replacement Silver Fix on and after August 15, 2014 with respect to the pricing of silver, the value of the DBP Fund’s silver futures contracts and the value of the shares of the DBP Fund may be affected adversely to the extent that the Replacement Silver Fix experiences unexpected issues or has inherent design flaws, if any.”

Footnotes to Performance Information

1.             “Aggregate Gross Capital Subscriptions” is the aggregate of all amounts ever contributed to the relevant pool, including investors who subsequently redeemed their investments.

2.             “Net Asset Value” is the net asset value of the relevant pool as of May 31, 2014.

3.             “Net Asset Value per Share” is the Net Asset Value of the relevant pool divided by the total number of Shares outstanding with respect to such pool as of May 31, 2014.

4.             “Worst Monthly Drawdown” is the largest single month loss sustained since inception of trading. “Drawdown” as used in this section of the Prospectus means losses experienced by the relevant pool over the specified period and is calculated on a rate of return basis, i.e., dividing net performance by beginning equity. “Drawdown” is measured on the basis of monthly returns only, and does not reflect intra-month figures. “Month” is the month of the Worst Monthly Drawdown.

5.             “Worst Peak-to-Valley Drawdown” is the largest percentage decline in the Net Asset Value per Share over the history of the relevant pool. This need not be a continuous decline, but can be a series of positive and negative returns where the negative returns are larger than the positive returns. “Worst Peak-to-Valley Drawdown” represents the greatest percentage decline from any month-end Net Asset Value per Share that occurs without such month-end Net Asset Value per Share being equaled or exceeded as of a subsequent month-end. For example, if the Net Asset Value per Share of a particular pool declined by $1 in each of January and February, increased by $1 in March and declined again by $2 in April, a “peak-to-valley drawdown” analysis conducted as of the end of April would consider that “drawdown” to be still continuing and to be $3 in amount, whereas if the Net Asset Value per Share had increased by $2 in March, the January-February drawdown would have ended as of the end of February at the $2 level.

6.             “Compound Rate of Return” of the relevant pool is calculated by multiplying on a compound basis each of the monthly rates of return set forth in the respective charts above and not by adding or averaging such monthly rates of return. For periods of less than one year, the results are year-to-date.

7.             The below table reflects both the name of the original Index that each Fund has tracked up to and including December 31, 2010, or Original Index, and the name of the Index that each Fund will track after December 31, 2010, or Renamed Index:

Each Fund’s Original Index is identical to the Renamed Index, except with respect to the following non-substantive changes: (i) name of Index and (ii) ticker symbol. The above Inception Dates remain identical. The Rename Date of October 2010 reflects the date on which each Original Index changed its name as reflected in the Renamed Index column above and each such change and became effective in January 3, 2011. 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, Inception Date, rolling, etc.) with respect to each Original Index is identical to its corresponding Renamed Index.

DBLCI™ and Deutsche Bank Liquid Commodity Index™ are trade marks of the Index Sponsor and are the subject of Community Trade Mark Nos. 3055043 and 3054996. Trade Mark applications in the United States are pending with respect to both the Trust and aspects of each Index. The Fund and the Managing Owner have been licensed to use DBLCI™, Deutsche Bank Liquid Commodity Index™ and DBIQ™.

WHILE THE FUND’S OBJECTIVE IS NOT TO GENERATE PROFIT THROUGH ACTIVE PORTFOLIO MANAGEMENT, BUT IS TO TRACK THE INDEX, BECAUSE THE INDEX WAS ESTABLISHED IN OCTOBER 2010, CERTAIN INFORMATION RELATING TO INDEX CLOSING LEVELS MAY BE CONSIDERED TO BE “HYPOTHETICAL.” HYPOTHETICAL INFORMATION MAY HAVE CERTAIN INHERENT LIMITATIONS, SOME OF WHICH ARE DESCRIBED BELOW.

NO REPRESENTATION IS BEING MADE THAT THE INDEX WILL OR IS LIKELY TO ACHIEVE ANNUAL OR CUMULATIVE CLOSING LEVELS CONSISTENT WITH OR SIMILAR TO THOSE SET FORTH HEREIN. SIMILARLY, NO REPRESENTATION IS BEING MADE THAT THE FUND WILL GENERATE PROFITS OR LOSSES SIMILAR TO THE FUND’S PAST PERFORMANCE, WHEN AVAILABLE, OR THE HISTORICAL ANNUAL OR CUMULATIVE CHANGES IN THE INDEX CLOSING LEVELS. IN FACT, THERE ARE FREQUENTLY SHARP DIFFERENCES BETWEEN HYPOTHETICAL RESULTS AND THE ACTUAL RESULTS SUBSEQUENTLY ACHIEVED BY INVESTMENT METHODOLOGIES, WHETHER ACTIVE OR PASSIVE.

ONE OF THE LIMITATIONS OF HYPOTHETICAL INFORMATION IS THAT IT IS GENERALLY PREPARED WITH THE BENEFIT OF HINDSIGHT. TO THE EXTENT THAT INFORMATION PRESENTED HEREIN RELATES TO THE PERIOD JUNE 1990 THROUGH SEPTEMBER 2010, THE INDEX CLOSING LEVELS REFLECT THE APPLICATION OF THE INDEX’S METHODOLOGY, AND SELECTION OF INDEX COMMODITIES, IN HINDSIGHT.

NO HYPOTHETICAL RECORD CAN COMPLETELY ACCOUNT FOR THE IMPACT OF FINANCIAL RISK IN ACTUAL TRADING. FOR EXAMPLE, THERE ARE NUMEROUS FACTORS, INCLUDING THOSE DESCRIBED UNDER “THE RISKS YOU FACE” HEREIN, RELATED TO THE COMMODITIES MARKETS IN GENERAL OR TO THE IMPLEMENTATION OF THE FUND’S EFFORTS TO TRACK ITS INDEX OVER TIME WHICH CANNOT BE, AND HAVE NOT BEEN, ACCOUNTED FOR IN THE PREPARATION OF SUCH INDEX INFORMATION SET FORTH ON THE FOLLOWING PAGES, ALL OF WHICH CAN ADVERSELY AFFECT ACTUAL PERFORMANCE RESULTS FOR THE FUND. FURTHERMORE, THE INDEX INFORMATION DOES NOT INVOLVE FINANCIAL RISK OR ACCOUNT FOR THE IMPACT OF FEES AND COSTS ASSOCIATED WITH THE FUND.

THE MANAGING OWNER COMMENCED OPERATIONS IN JANUARY 2006. AS MANAGING OWNER, THE MANAGING OWNER AND ITS TRADING PRINCIPALS HAVE BEEN MANAGING THE DAY-TO-DAY OPERATIONS FOR THE FUNDS AND RELATED PRODUCTS AND MANAGING FUTURES TRADING ACCOUNTS. BECAUSE THERE ARE LIMITED ACTUAL TRADING RESULTS TO COMPARE TO THE INDEX CLOSING LEVELS SET FORTH HEREIN, PROSPECTIVE INVESTORS SHOULD BE PARTICULARLY WARY OF PLACING UNDUE RELIANCE ON THE ANNUAL OR CUMULATIVE INDEX RESULTS.
