On September 22, 2008, Williams Partners L.P. (the "Partnership") announced an update of the Discovery system following Hurricane Ike in the Gulf of Mexico. In addition to providing an operational update in the announcement, the Partnership announced that its initial estimate on the financial effect of the hurricane-related damages is 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. This amount includes the Partnership's share of the deductible for Discovery's hurricane property insurance, which is approximately $3.8 million, as well as the interruption in services. The Partnership announced that it does not expect any impact on the Partnership's regular cash distribution to unitholders for third-quarter 2008. 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.
