Dear Investor,

Losses in Fixed Income & Commodities Largely Offset by Strong Gains in Equity
Indices Trading.

The month of July held two distinct phases for most asset classes, with the
overall environment dominated by reversals.

The Fund captured profits in equity indices trading early in the month despite
late month stabilization, particularly in the U.S. Intra-month swings in global
indices were significant. The DJIA and the S&P hit technical bear market
territory during the month, while Japanese equities saw the longest back-to-back
daily losing streak in 54 years. Equity markets did find their bottom mid-month,
after the U.S. announcement of a Government-Sponsored Enterprises (GSE) bail-out
plan.

Gains earned in equity indices trading offset the majority of losses incurred in
interest rates and commodities trading. Lower commodity prices led to position
short-covering in the face of reduced inflation worries in the Euro-Zone,
pushing bond futures higher. Crude Oil declined almost 12% for the month on
fears that weakening economic conditions would reduce global demand.

Foreign exchange trading finished relatively flat as the Euro hit a new high,
commodity-linked currencies fell, and the broad dollar index gained against most
major currencies.

As always, please call if we can be of any assistance.

Sincerely,

Terri Becks
