Sony/ATV is a joint venture between Sony Corp. and the estate of Michael Jackson.

In November 2011, an investor group that included Sony Corporation of America and the Estate of Michael Jackson, Mubadala Development Company PJSC, Jynwel Capital Limited, the Blackstone Group's GSO Capital Partners LP and David Geffen signed an agreement to acquire EMI Music Publishing. Subject to regulatory approval, Sony/ATV Music Publishing will help oversee EMI Music Publishing and reunite Mr. Bandier with a company he spent over 17 years building. He helmed EMI Music Publishing from 1989 until early 2007, and then joined Sony/ATV in March of that year.

"Working at Sony/ATV Music Publishing, especially with its talented artists, songwriters and staff," Bandier said, "has been one of the best highlights of my career."
