Provides Fiscal Fourth Quarter and Full Year Results for

Recently Acquired FCStone Group

New York, NY – December 14, 2009 – International Assets Holding Corporation (the ‘Company’; NASDAQ: IAAC) today announced its fiscal year 2009 financial results. Certain financial metrics discussed in this press release are non-GAAP, reflecting marked-to-market differences in the Company’s commodities business. A reconciliation of those metrics to GAAP equivalents is provided in the table below, and further discussion of the use of non-GAAP metrics is provided in the Company’s Form 10-K, to be filed with the Securities and Exchange Commission (“SEC”).

Sean O’Connor, CEO of International Assets, stated, “Despite challenging market conditions we recorded improved non-GAAP earnings over the prior-year quarter and another record result for the year overall, with a 16% adjusted return on average equity, excluding the extraordinary gain related to the merger with FCStone. For the year, we posted 9% growth in adjusted operating revenues and 23% growth in adjusted pro forma net income from continuing operations with all businesses except equity trading achieving double digit revenue growth rates. Adjusted book value per share increased to $14.16 per share.

“On September 30 we completed our merger with FCStone, beginning a new era for International Assets. This strategic combination of complementary and like-minded businesses provides an enhanced platform for growth that should provide attractive long term returns to our investors.”
