Reid was appointed president and CEO of the Island Def Jam Music Group after he was dismissed from Arista Records. Cohen left Island Def Jam to join Warner Music Group, bringing with him, his colleagues, Kevin Liles and Julie Greenwald. In December, the unit acquired the remaining 50% interest in Roc-A-Fella Records in exchange for appointing co-founder Jay-Z president of Def Jam Recordings; the other 50% had been purchased by former Def Jam parent company, PolyGram, in 1997.
