Shares of Pacific Gas and Electric Co. fell 1.3% in premarket trade Thursday, after the San Francisco-based utility said it accepts the determination that its electrical transmission lines were the cause of November's Camp Fire that killed at least 85 people. The determination was made by the California Department of Forestry and Fire Protection (CAL FIRE). "While we have not been able to review CAL FIRE's report, its determination that PG&E transmission lines near the Pulga area ignited the Camp Fire on the morning of November 8, 2018, is consistent with the company's previous statements," PG&E said in a statement. "We have not been able to form a conclusion as to whether a second fire ignited as a result of vegetation contact with PG&E electrical distribution lines, as CAL FIRE also determined." The stock has tumbled 24% year to date through Wednesday, while the SPDR Utilities Select Sector ETF has gained 9.8% and the S&P 500 has advanced 14%.
