Dear Investor,

Strong Gains Posted on Global Equity Market Decline

Equity indices trading produced strong gains for the Fund as short positions
benefited from the negative news that roiled markets around the globe. Signs of
commodity-based inflation were constantly in the headlines and consumer
confidence fell to a 16-year low. In the U.S., the Dow finished its worst
performance for the month of June in over 75 years, and European and Asian
equities fell in tandem.

Additional gains were recorded in interest rates trading, particularly in
Europe, in response to the ECB's increasingly hawkish stance and fears of
inflation. Energy trading also contributed as crude oil hit new highs on the
back of escalating tensions between Israel and Iran, and amongst OPEC members.

Foreign Exchange trading results were slightly positive, due to central banks
being forced to choose between growth and inflation, driving dollar weakness,
and a higher Euro.

We are confident that our passion for a disciplined investment process, combined
with our focus on continuous research, will compel us to take optimal advantage
of these difficult market conditions. Please reach out to me with any questions
or comments.
Sincerely,

Terri Becks
