Fund results for April 2008:

World bond markets moved lower in April as growing inflation readings added to late March’s weakness. U.S. bonds rallied early in the month as unemployment reached its highest level since September 2005 and consumer confidence sank to a 26 year low. Values then moved lower as PPI exceeded expectations while consumer prices rose due to higher fuel and food costs. At month end, the FOMC cut rates by 25 basis points as expected, voicing growth concerns and uncertainty on inflation. In Europe, manufacturing growth fell while business confidence reached a 2 year low. Mixed data in Japan led the BOJ to leave rates unchanged as consumer prices increased at the fastest pace in a decade and manufacturing confidence fell to a 4 year low. Long positions resulted in a loss for this market sector.

World energy markets moved sharply higher in April as a variety of bullish inputs propelled crude oil futures (+12.3%) to new all time highs. Ongoing U.S. Dollar weakness provided early support, while strong demand from developing nations such as China and India, bullish domestic inventory reports, and continued geopolitical concerns provided support throughout the month. Rebel attacks in Nigeria were said to have resulted in a 50% cut in output as major producers declared force majeure. Natural gas futures (+6.4%) rose to their highest level since the hurricane plagued fall of 2005. Meanwhile, heating oil and gasoline futures continued to add to all time highs, posting solid gains of 10.7% and 10.8%, respectively, as refinery capacity utilization has now declined 47% from a year ago amid disappointing margins. This led our long positions to an overall gain in the energy sector.

Other market sectors, relative to the sectors mentioned above, did not reveal significant trends and did not have a major influence on this month’s slightly negative performance.

For the month of April 2008, Series A lost 1.57% and Series B lost 1.20%, net of all fees and expenses.
