In the wake of yesterday's news that Antonio "L.A." Reid will be leaving his post at Island Def Jam  to become a judge on Simon Cowell's "X Factor" (and possibly to join his old boss Doug Morris at Sony), Billboard.biz has obtained the text of his farewell letter to the staff, which follows:
"Great leaders are almost always great simplifiers, who can cut through argument, debate and doubt, to offer a solution everybody can understand."
To my Island Def Jam family:
After much consideration, I have decided to leave my position as Chairman of the Island Def Jam Music Group.
I have always thrived on growth and the next great challenge, and I look forward with much enthusiasm to what the future holds.
I am extremely proud of our beautiful roster and all we have accomplished in my seven years with IDJ. We continue to have incredible success together with today's most phenomenal superstars - Rihanna, Justin Bieber, Mariah Carey, Kanye West, Bon Jovi, Jennifer Lopez, Ne-Yo, Rick Ross, The Killers, The-Dream, Chrisette Michele, Jeezy and Ludacris to name a few.
I want to thank all of you for your amazing contributions.
With Warm Regards -
