Dear Investor,

Diversification Helps Limit Losses in a Dramatic Commodity Reversal...

In many ways, the commodity markets took center stage in May as the Fund put
another volatile month behind. The petroleum complex sold off substantially on
May 5th, despite the lack of any oil-related fundamental data. In addition,
precious metals saw a significant decline with the price of silver dropping
24%,giving back the entire April rally. While the Fund suffered losses in these
sectors, our models significantly reduced long commodity exposure on the abrupt
reversal in price action and spike in volatility throughout the month.

Trading in global equities also generated losses on softer economic data, Wall
Street lowering U.S. growth forecasts, and renewed European sovereign debt
concerns mainly focused on Greece. While positions have been reduced in this
sector, regional risk was rotated out of Europe and back to the U.S.

Losses were also recorded in currency trading as the U.S. Dollar rallied
against most major currencies. The Fund's long Euro position produced the
biggest currency loss, as the European Central Bank disappointed expectations
of rate hikes at its May policy meeting.

Fixed income trading produced strong positive results, helping to mitigate
losses in riskier assets as the flight-to-quality theme was dominant in May.

Once again, a steady risk posture and a discipline centered on diversification
helped the Fund navigate a very volatile month for our strategy space.

Please do not hesitate to call me with questions.

Sincerely,

Terri Becks
