The AirShares EU Carbon Allowances Fund (ASO) will halt trading and liquidate effective July 31, 2009.

XShares Advisors determined that, as a result of the Fund’s small size, inability to attract significant market interest since its inception and future viability, as well as the prospects for growth in the Fund’s assets in the foreseeable future, it was advisable and in the best interests of the Fund and its shareholders to liquidate the Fund.
