Yahoo's former chief operating officer Henrique de Castro was not the right fit for the company, CEO Marissa Mayer said on Wednesday.
De Castro was fired earlier this year, garnering $58 million in severance for 15 months of work.
Mayer, speaking live at the TechCrunch Disrupt conference in New York, dodged the question of whether de Castro's hiring was her biggest regret as CEO.
"I think it was the right time for us to go our separate ways," Mayer said. "There were issues there that I potentially created, and it was important to me to fix them."
