Item 7.01. Regulation FD Disclosure.
On October 10, 2008, Williams Partners L.P. (the "Partnership") announced the second update of the Discovery system following the hurricanes in the Gulf of Mexico as well as the expected effect on its financial results. In addition to providing an operational update in the announcement, the Partnership announced that its previous third-quarter 2008 guidance for the expected financial effect of the hurricane-related damages and downtime is unchanged. The Partnership announced that it continues to expect a reduction in third-quarter 2008 consolidated segment profit of $6 million to $10 million, based on the Partnership's 60-percent equity earnings in Discovery. The Partnership announced that it does not expect Discovery's resulting third-quarter 2008 equity earnings to be materially different from its second-quarter 2008 equity earnings of $8.6 million. For fourth-quarter 2008, the Partnership expects a reduction in consolidated segment profit of $10 million to $20 million, also based on the 60-percent equity earnings in Discovery. As a result, the Partnership expects Discovery's equity earnings for fourth-quarter 2008 to range from a loss of $10 million to breakeven. The Partnership's estimates above for the expected effect on its results reflect its portion of Discovery's property insurance deductible, but do not reflect any potential future recoveries under the Partnership's business interruption insurance policy. The Partnership also announced that it does not does not expect any impact on its third or fourth quarter 2008 cash distributions to unitholders as a result of the hurricanes. The Partnership owns 60 percent of the Discovery system, which includes an offshore natural gas gathering system, as well as the Larose natural gas processing plant and Paradis fractionation facility. Both processing facilities are onshore south of New Orleans.
