Dear Investor,

Strong March and a Solid Q1

Strong performance from several sectors contributed to a strong March and a
solid finish to Q1. We are also pleased to note that most portfolios and funds
that we manage are now at new all-time highs.

The biggest gains in March were in FX, as the US Dollar rallied in response to
expectations of further interest rate hikes. Correspondingly, US and Euro
fixed income instruments had their worst quarter in several years, which
benefited our short positions. Energy prices rebounded profitably from
February's sell-off on renewed production and supply concerns, but this was
not enough to restrain equity prices, and the Equity Indices sector also
finished higher. Many of the Base and Precious metals again made new highs,
and contributed positively to our returns.

Please contact me at any time if I can be of assistance.

Sincerely,

Bruce Cleland
President & CEO
