Fund results for August 2012:

          The Fund’s strategies produced moderately disappointing results in August as guidance from central bankers increased investor appetite for risk. European Central Bank (“ECB”) president Mario Draghi’s late July statement that the he would do “whatever it takes” to preserve the euro proved to be the driving force behind a rally in European equity markets. German Chancellor Angela Merkel reaffirmed her country’s support for the ECB’s approach, increasing expectations for monetary stimulus. U.S. equities rallied in tandem with Europe, aided by a series of positive economic data, with the S&P 500 reaching a four-year high. U.S. Federal Reserve (the “Fed”) minutes released in advance of the highly anticipated Jackson Hole symposium revealed the Federal Open Market Committee’s (“FMOC”) intention to implement a third round of quantitative easing unless the strength and pace of economic recovery improves soon. Energy markets rallied markedly, lifted by U.S. and euro-zone optimism, heightened tensions in the Middle East, and the falling U.S. dollar. The drought gripping the U.S. Midwest drove corn and soybean to all-time highs. The Fund’s short-term strategies underperformed with losses in equities, energies and currencies.

          The Fund’s positions in equities underperformed in August as European leaders worked to improve the region’s fiscal position, reducing anxiety over euro-zone debt issues. Yields in Spain and Italy fell back on increasing expectations that the ECB will take action to avoid default. Equities in the U.K. (+1.8%), Italy (+8.9%), and Spain (+10.5%) all finished with gains in spite of weak economic data. France (+3.6%) and Germany (+2.7%) managed to avoid recession during the second quarter, outperforming their EU neighbors. In the U.S., the S&P500 (+2.2%) also gained, posting a four-year high. Asian equities in Japan (+1.6%) and Taiwan (+3.3%) finished on the plus side while stocks in China (-4.3%) fell as exports slowed.

          The Fund’s bond positions posted disappointing results in August as U.S. treasuries sold off steadily throughout the first half of the month in response to positive

economic data and euro-zone optimism. Retail sales rose for the first time in four months while an encouraging 1.8% gain in housing prices signaled a strengthening economy. Reduced demand for safe-haven assets lifted U.S. 10-year note yields to an intraday three-month high of 1.86% before falling after Fed minutes alluded to the possible need for further stimulus. Positive economic news in Europe also contributed to risk appetite with better-than-expected GDP data from Germany (+0.3%) and France (unchanged), pressuring German Bunds.

          The Fund’s positions in the energies sector benefited in August as the uptrend in the crude oil complex that began in July continued. Stronger employment data in the U.S. and an easing of European economic fears boosted the crude market early on expectations for increased demand. Inventory reports showed both crude and heating oil shrunk with heating oil inventories falling to a seasonally adjusted 4-year low. Tensions in the Middle East showed no signs of abating as hostilities continued to escalate in Syria. Crude prices climbed 9.6% while heating oil rose 11.5%. Natural gas prices fell back sharply, -12.8% to $2.799 per million btu, as the supply glut rose still further and temperatures moderated.

          The Fund’s allocation to currencies produced negative results in August. High expectations on the latest ECB meeting went unmet as little new information was revealed and rates were left unchanged. Germany’s firm support of the euro and Greece’s reaffirmed dedication to meeting bailout targets, bolstered confidence. As a result, both the euro (+2.2%) and British pound (+1.3%) gained ground. The U.S. dollar (-1.8%) was mostly weaker as the slow pace of U.S. growth prompted the FMOC to suggest that additional stimulus might be necessary to spur a sustainable recovery. The Australian dollar (-1.5%) fell as weakening Chinese demand threatened to dampen exports. The Japanese yen (-0.3%) lost ground early on weak economic data but quickly rebounded.
