PG&E Corp. PCG, -1.48% , California's largest utility, may tell its workers it's preparing for a possible bankruptcy filing as soon as Monday, Bloomberg News reported Sunday. Separately, Reuters reported PG&E is in talks with investment banks to get financing through bankruptcy proceedings. The utility has seen its shares battered as it faces the possibility of tens of billions of dollars in liabilities from devastating wildfires caused by PG&E power lines. According to state law, businesses must notify employees of a change in control, which includes bankruptcy, at least 15 days in advance. Bloomberg reported PG&E could still decide not to file for bankruptcy protection after alerting its employees. According to Reuters, PG&E is seeking $3 billion to $5 billion in debtor-in-possession financing, and that number may rise. The Wall Street Journal reported Sunday that the company's equipment started at least 1,500 California fires in recent years.
