Dear Investor,

Losses Sustained Across All Sectors in March...

The "V-shaped" behavior in most sectors during the month can be widely
attributed to global stock market volatility compounded by the devastating
earthquake and resulting tsunami in Japan, followed by upside surprises to
manufacturing data and other economic activity as the month came to a close.

Global stock markets were extremely volatile in March as the Middle East/North
Africa (MENA) unrest and Europe's sovereign debt crisis both worsened prior to
the crisis in Japan that concluded with threats of a nuclear reactor emergency.
While the Nikkei finished down approximately 8% for the month, the U.S. stock
market was relatively unchanged despite large mid-month swings. The Trust
adjusted to the abrupt price swings by reducing long equity exposure over 50%
(region specific) by mid-month across the U.S., Europe and Asia. Stock indices
trading was the worst performing sector for the month.

Commodities took their cue from the Equity markets in reacting to the "twin
shocks," with particular impact on base metal prices. Risk-aversion-based gains
from long positions in energies and precious metals were not enough to overcome
losses in nickel, copper and corn.

Currency trading also proved challenging as Central Banks intervened, in a
resolute way, in response to excess volatility and disorderly movements in
exchange rates that were perceived as having adverse implications for economic
and financial stability. In particular, the Trust's short position in the
Japanese Yen suffered as a result of the repatriation of Yen back to Japan.

While risk exposures were light in fixed income trading, small losses were
incurred in both short-term and long-term rates due to choppy market price
action.

From Libya to Japan to G7 intervention, March seemed determined to reinforce the
definition of "exogenous events." Though March challenged the Trust's risk
appetite, risk ranges are "normal" as of the month's end and the Trust's
systematic approach is fully engaged to hopefully benefit from ongoing market
volatility.

Please do not hesitate to call with questions.

Sincerely,

Terri Becks
