The United States Natural Gas Fund, LP ("UNG") is a new way for investors and hedgers to manage their exposure to energy.

The United States Natural Gas Fund LP (UNG) is an exchange traded security that is designed to track in percentage terms the movements of natural gas prices. UNG issues units that may be purchased and sold on the American Stock Exchange.

The investment objective of UNG is for the changes in percentage terms of the units’ net asset value to reflect the changes in percentage terms of the price of natural gas delivered at the Henry Hub, Louisiana, as measured by the changes in the price of the futures contract on natural gas traded on the New York Mercantile Exchange that is the near month contract to expire, except when the near month contract is within two weeks of expiration, in which case it will be measured by the futures contract that is the next month contract to expire, less UNG's expenses.

The 2007 K-1s are scheduled to be mailed out the week of March 10, 2008

2007 K-1s are also available online
