She is a single mother named Jodie Fisher. She was contracted as a greeter and organizer for HP. She is also an actress; she appeared in several minor films in the 1990s. In her public statement, she said she and Hurd "never had an affair or intimate sexual relationship," and, "I have resolved my claim with Mark privately, without litigation."
More poignantly, she expressed regret that the investigation caused Hurd to lose his job. "I was surprised and saddened that Mark Hurd lost his job over this," she said. "That was never my intention."
While Hurd is facing a very public kind of humiliation right now, his departure isn't a complete disaster. According to Bloomberg BusinessWeek, his severance package included $12.2 million in cash and $16 million in stock. Still, depending on what happened exactly, the consequences for his personal life and reputation may overshadow the payout.
The company claims that Hurd didn't violate its sexual discrimination policy — as Fisher said, they never had a sexual relationship, so it's any outsider's guess exactly what occurred — but that he violated its "Standards of Business Conduct." Hurd explained his departure by saying, "I realized there were instances in which I did not live up to the standards and principles of trust, respect and integrity that I have espoused at HP and which have guided me throughout my career."
