Footnotes to Performance Information

1. “Aggregate Gross Capital Subscriptions” is the aggregate of all amounts ever contributed to the pool.

2. “Net Asset Value” is the net asset value of the pool as of December 31, 2012.

3. “Net Asset Value per Share” is the Net Asset Value of the pool divided by the total number of Shares outstanding as of December 31, 2012.

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. The Worst Peak-to-Valley Drawdown from June 2008 – February 2009 includes the effect of the $0.34 per Share distribution made to Shareholders of record as of December 17, 2008. “Worst Peak-to-Valley Drawdown” is the largest percentage decline in the Net Asset Value per Share over the history of the 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. The December 2008 return of (6.71)% includes the $0.34 per Share distribution made to Shareholders of record as of December 17, 2008. Prior to the December 30, 2008 distribution, the pool’s return for December 2008 was (5.23)%.

7. The December 2007 return of 3.76% includes the $0.76 per Share distribution made to Shareholders of record as of December 19, 2007. Prior to the December 28, 2007 distribution, the pool’s return for December 2007 was 6.23%.

8. As of October 19, 2009, the Fund commenced tracking the Deutsche Bank Liquid Commodity Index–Optimum Yield Diversified Excess Return™, or the Interim Index. Prior to October 19, 2009, the Fund tracked the Deutsche Bank Liquid Commodity Index–Optimum Yield Excess Return™.

9. Effective January 1, 2011, the Fund commenced tracking DBIQ Optimum Yield Diversified Commodity Index Excess Return™, or the Renamed Index. The Fund’s Renamed Index is identical to the Interim Index except with respect to the name of Index. The inception date of January 2007 remains identical. 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 the Renamed Index are identical to the Interim Index.

10. “Compound Rate of Return” is based on an initial net asset value per share of $24.25 and is calculated by multiplying on a compound basis each of the monthly rates of return set forth in the chart 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.”
