| Exports                     | Natural Gas deliveries out of the Continental United States and Alaska to foreign countries.                                                                                                                                                                                                                                                                                   |
| Liquefied Natural Gas (LNG) | Natural gas (primarily methane)that has been liquefied by reducing its temperature to -260degrees Fahrenheit at atmospheric pressure.                                                                                                                                                                                                                                        |
| Pipeline                    | A continuous pipe conduit, complete with such equipmentas valves, compressor stations, communications systems,and meters, for transporting natural and/or supplemental gasfrom one point to another, usually from a point in or beyond theproducing field or processing plant to another pipeline or topoints of use. Also refers to a company operating such facilities. |
| CNG                         | CNG = Compressed Natural Gas: Natural gas compressed to a pressure at or above 200-248 bar (i.e., 2900-3600 pounds per square inch) and stored in high-pressure containers.                                                                                                                                                                                                    |

|  | Annual and final monthly data are published from the Office of Fossil Energy, 		U.S. Department of Energy, *Natural Gas Imports and Exports*, which requires data to be 		reported each quarter by month for the calendar year.  
        Preliminary monthly export data are based on historical data from the Office of Fossil 		Energy, U.S. Department of Energy, *Natural Gas Imports and Exports*; informal industry 		contacts, and information gathered from natural gas industry trade publications.   
        LNG prices are a volume-weighted average of the prices reported by cargo.  See the LNG Monthly from the Office of Fossil Energy, U.S. Department of Energy, for more information on what is included in the individual LNG prices. |
