NEW YORK (AP) — The CEO of Patriot Coal is stepping aside less than five months after taking the job. Irl Engelhardt, a long-time executive at Peabody where he served as chairman and director of one of the world’s largest coal producers, took over this year just weeks before the troubled Peabody spin-off sought bankruptcy protection.

The company did not provide more details about the change at the top of the company, or about changes to corporate governance announced Wednesday.
