The Bache Commodity IndexSM (BCISM) is a transparent, fully investable com-

modity index. Our unique method of constructing the index results in lower turn-over and lower risk than other commodity indices, while maintaining the poten-tial returns. Predictable, Consistent ExposurePredictable, Consistent ExposurePredictable, Consistent ExposurePredictable, Consistent Exposure

The BCISM is designed so that the index does not become dominated by a single

commodity sector or by several commodities within a commodity sector. This is accomplished by employing upper and lower bounds on investment in each sec-

tor and each commodity, and by rebalancing the BCISM each day to maintain the

desired exposure to each commodity market.

BCIBCIBCIBCISM Benefits from Multiple Sources of Return Benefits from Multiple Sources of Return Benefits from Multiple Sources of Return Benefits from Multiple Sources of Return

The BCISM is designed to capture more sources of return to investing in com-

modities than are available with existing commodity indices. In our historical tests, our asset allocation and roll methods contributed an additional 45% to the total return over a 15-year period. Momentum Means Greater Return, Less RiskMomentum Means Greater Return, Less RiskMomentum Means Greater Return, Less RiskMomentum Means Greater Return, Less Risk Commodity markets have historically exhibited short-term momentum. Our view is that using momentum to decide which positions to reduce and which to in-crease is more profitable than holding fixed positions. By tactically reducing the

risk of different commodities, the BCISM holds an average of 30% less exposure

than a fully invested strategy. As a result, the volatility of the BCISM is roughly

30% less than equivalent indices. Diversification, Inflation Hedge for PortfoliosDiversification, Inflation Hedge for PortfoliosDiversification, Inflation Hedge for PortfoliosDiversification, Inflation Hedge for Portfolios

Like other commodity indices on the market, the BCISM offers positive returns,

may offer some inflation protection, and diversification benefits. Unlike other

indices, the BCISM offers these benefits while reducing the downside risk that

can occur with commodity investing.

Performance SummaryPerformance SummaryPerformance SummaryPerformance Summary

In the second quarter of 2008, the Bache Commodity IndexSM (BCISM) posted a return of nearly 20%, setting an all-time high during the quarter. Exhibit 1 at left summarizes the daily growth of the total return indexi during the quarter. While the Agriculture sector re-turned a substantial 10.8%, the real story was Energy, with the sector value soaring 35.4% for the quarter. Both the BCI Energy composite and the BCI Agriculture composite also set all-time highs. Exhibit 2 at left shows the composite index, sector, and individual commod-ity performance for the quarter. As shown in Exhibit 3 below, the average return during the quarter was 6.2%, far surpassing the long-run average monthly return of 1.0%.

Economic Environment for CommoditiesEconomic Environment for CommoditiesEconomic Environment for CommoditiesEconomic Environment for Commodities Global Economic GrowthGlobal Economic GrowthGlobal Economic GrowthGlobal Economic Growth The second quarter saw an increasingly troubled global economy, with tight credit condi-tions, rising energy and food prices, and a struggling U.S. housing market weighing on growth. Inflation flourished as energy prices skyrocketed and food prices shadowed that rise. The rising costs of food fuelled instability in lower-income countries around the world. The finance ministers from the Group of Eight industrialized nations stated in June that escalating oil and food prices posed a serious challenge to stable growth worldwide. Inflation was pervasive, spreading globally throughout the quarter. Some 50 economies around the world were posting inflation above 10%, according to analyst reports. The Inter-national Monetary Fund (IMF) warned in June that the inflation speed-up could undermine prospects for restoring the low-inflationary, solid growth that prevailed earlier in the dec-ade. Shifts in global growth projections seemed to play out those fears. According to the Organisation for Economic Co-operation and Development (OECD), eco-nomic growth overall in the 30 developed OECD economies will slow to 1.8% this year and 1.7% in 2009. That projection marks a significant decline from the group’s December 2007 forecast of 2.3% for 2008 and 2.4% for 2009. The OECD said that the global outlook is being dragged down by the U.S. economy, which is predicted to expand just 1.2% this year and 1.1% in 2009, compared to previous OECD growth forecasts for the U.S. of 2.0% in 2008 and 2.2% in 2009.

The U.S. economy expanded 1.0% in the first quarter of 2008 from the fourth quarter of 2007, according to final data from the U.S. Department of Commerce. The odds of the U.S. entering a reces-sion in the next 12 months were 50%, according to the median forecast of 61 economists in a June Bloomberg survey. The OECD expects economic growth for both the Euro area and Japan to be 1.7% for this year. With the combination of increasing inflation but sluggish growth, the European Central Bank (ECB) and the Bank of Japan opted to leave benchmark interest rates static in the second quarter. The U.S. Federal Reserve, however, lowered its target for the federal funds rate by another 25 basis points to 2.0% in late April. At the end of the quarter, the yen fell to a record low against the euro on speculation the ECB might increase interest rates in the third quar-ter. Surprisingly, currency volatility fell in the second quarter by the most since 1999. The drop in volatility may indicate that traders are comfortable with the relative valuation of the major currencies. Rising inflation also seemed to weigh on global stock markets in the second quarter. The S&P 500 Total Return Index fell 2.73% for the second quarter, and the MSCI World Index was 1.66% lower. The Lehman Global Aggregate Index fell 2.91% for the quarter.

Comparison with Commodity BenchmarksComparison with Commodity BenchmarksComparison with Commodity BenchmarksComparison with Commodity Benchmarks Given the significant outperformance of the Energy sector over the past year, the major commodity indices performed relative to the size of their allocations in energy products. The S&P Goldman Sachs Commodity Index (SPGSCI) has the largest allocation to en-ergy of the three indices. The BCISM total return index underper-formed the SPGSCI over the past year, but mostly outperformed the Dow Jones-AIG Commodity Index (DJAIG). Exhibit 7 shows relative performance of the three indices. Due to its lower volatility, the BCISM outperformed the other benchmarks on a risk-adjusted (Sharpe ratio) basis during the second quarter of 2008 and for the first six months of the year.

Contribution of Individual Commodity MarketsContribution of Individual Commodity MarketsContribution of Individual Commodity MarketsContribution of Individual Commodity Markets Eight commodities accounted for the entire gain in the BCISM during the second quarter. The six energy markets, Corn, and Soybeans each increased more than 20% in value dur-ing the quarter. The combined contribution of the remaining 11 commodity markets was close to zero. It is unusual to see such highly concentrated movement in the index. In 2007, for example, there was a much broader rally with participation from each of the ma-jor commodity sectors. Exhibit 8 shows the contribution of each commodity market to the overall BCISM performance in the second quarter. Exhibit 9 shows the contribution of each commodity sub-sector to the overall BCISM performance in the second quarter.

The Beta Factoriii was once again the dominant driver of BCISM returns, accounting for 14.54% of the

19.85% earned by the BCI� in the second quarter. The Structured Asset Allocation Factoriv

added 4.27% to the BCI�. This is well above the long-run average contribution of this fac-tor, which averaged 220 basis points per year from 1991-2006. The Daily Roll Factorv added an additional 55 basis points, and the Treasury Bill collateral returnvi added 49 ba-sis points to the BCISM total return.

Comparison of BCIComparison of BCIComparison of BCIComparison of BCISMSMSMSM Returns with a static commodity index Returns with a static commodity index Returns with a static commodity index Returns with a static commodity index

Exhibit 11 compares the return of the BCISMand BCISM sectors to the fully invested indexvii. The fully invested index excludes the structured asset allocation and the daily roll factors.

The BCI� slightly underperformed the static index during the second quarter in all sectors. However, in the second quarter the BCISM had a lower volatility than the fully invested index across all sectors (Exhibit 12) due to its risk reduction mechanism. Normally, this differ-ence is more pronounced. However, the asset allocation model kept most commodities in the Energy sector at or near full allocation during the quarter. After adjusting for relative

risk, the BCI� composite returned more than the fully invested index, and all sectors ex-cept metals outperformed their fully invested counterparts on a risk-adjusted basis. Exhibit 13 compares the risk-adjusted returns of the BCISM and BCISM sectors to the fully invested index.

SummarySummarySummarySummary A dramatic upsurge in inflation in the price of energy and agricultural products was detri-mental for global economic growth in the second quarter, but meant that commodity prices had a banner performance. The BCISM has positive returns in five out of six months thus far in 2008 and in 13 out of 18 months since the start of 2007. The global economic slowdown will inevitably be a drag on commodity prices. However, reflationary trends tend to play out over the course of years rather than months, so the current upward price trend could persist for some time.

* Returns prior to January 2007 are pro forma.

**Standard deviation is calculated as annualized standard deviation of daily total returns.

The returns presented in this document prior to February 1, 2007, were determined based on the pro forma calculations of the historical performance of the BCISM. Because the BCISM was not actually being calculated and published during these prior periods, and no actual trading was conducted in accordance with the BCISM, these returns could be considered to be hypothetical performance results. Hypothetical performance results have many inherent limitations, some of which are described below. No representation is being made that any trading program or strategy will or is likely to achieve profits or losses similar to those shown. In fact, there are frequently sharp differences between hypothetical performance results and the actual results subsequently achieved. One of the limitations of hypothetical performance results is that they are necessarily prepared with the benefit of hindsight and, if the BCISM were actually being calculated and published during these periods, it might have been based on different criteria and a differ-ent methodology. Moreover, the market conditions that existed during prior periods will most likely not be repeated and this difference could adversely affect performance. There are numerous factors related to the markets in general or the implementation of any in-vestment strategy, which cannot be fully accounted for in the preparation of hypothetical results and all of which can adversely affect actual trading results, including but not lim-ited to market liquidity, general levels of interest rates and the effect on the relevant mar-kets of political, economic or other external events. In addition, hypothetical performance results do not involve financial risk, and no hypothetical performance results can com-pletely account for the impact of financial risk in actual performance. The hypothetical performance results shown were derived from a model based on an asset allocation strategy and daily roll strategy. The hypothetical performance reflects the historical contract daily return plus daily interest on the funds hypothetically committed to the investment. The hypothetical performance returns are estimates using current and historical futures price data as described. Historical results should not and cannot be viewed as an indicator of future results. For a more complete description of the BCISM, reference is made to The Guide to the Bache Commodity IndexSM. The hypothetical performance results do not reflect any management fees, transaction costs or expenses which would reduce your actual return. Indexes are unmanaged and one cannot invest directly in an index. Past performance is no guarantee of future results.

Bache Commodities Group from time to time, issues reports based on fundamentals, such as expected trends in supply and demand, as well as reports based on technical factors, such as price and volume movements. Since such reports rely upon different criteria, there may be instances when their conclu-sions are not in concert.
