ITEM 9. REGULATION FD DISCLOSURE. CenterPoint Energy Resources Corp. ("CERC") is providing the following information regarding its third quarter 2003 results that CERC expects will be presented to various members of the financial and investment community from time to time. For the three months ended September 30, 2003: o revenues increased from $737 million to $950 million, o operating income decreased from $37 million to $33 million, and o net loss increased from $5 million to $10 million as compared to the same period in 2002. Operating income declined because continued growth and higher revenues from rate increases implemented in 2002 in the natural gas distribution segment did not completely offset higher expenses primarily related to increased pension and employee benefit expenses, depreciation and other taxes. In addition, the costs associated with a receivables facility, which was modified in November 2002, reduced operating income by $2 million, whereas prior to the amendment, these costs were included in interest expense. For the nine months ended September 30, 2003: o revenues increased from $2,848 million to $4,076 million, o operating income increased from $229 million to $272 million, and o net income increased from $72 million to $93 million as compared to the same period in 2002. Operating income increased primarily due to continued growth and higher revenues from rate increases implemented in 2002 in the natural gas distribution segment partially offset by higher expenses primarily related to increased pension and employee benefit expenses, depreciation and other taxes. In addition, the costs associated with a receivables facility, which was modified in November 2002, reduced operating income by $9 million, whereas prior to the amendment, these costs were included in interest expense.
