Fund results for April 2007:

World stock indices rallied steadily throughout April as the global equities uptrend reasserted itself. European stocks rose sharply with most major exchanges across the region posting gains. A better than expected IFO survey, strong consumer confidence, and an impressive German Industrial Orders figure supported the view that economic conditions in Europe remain strong. U.S. markets rallied as well, with the Dow Jones Industrial Average trading to a new all time high above 13,000 as foreign demand for U.S. stocks grew due to the weak dollar. Solid corporate earnings and strong employment also provided support. Long positions in this market sector produced gains for the Fund.

The U.S. Dollar sustained heavy losses against most currencies in April as prospects for interest rate hikes throughout the world increased relative to U.S. monetary policy. The Euro reached a new all time high against the greenback amid excellent economic reports and continued hawkish dialogue from central bankers. The British Pound surged to over $2 on rising CPI data and rumors of a tax break to companies that repatriate profits back to the U.K. The Australian Dollar gained on rising commodity prices. The Indian Rupee rose to near 9 year highs amid heavy capital flows tied to a strong stock market. The New Zealand Dollar again as strong retail sales and housing data resulted in a central bank rate hike. Relatively large gains resulted from long positions in this market 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 overall positive performance.

For the month of April 2007, Series A gained 7.99%, while Series B gained 11.38%, including all fees and expenses.
