Toshiba Corp has completed the sale of its chip unit to a consortium led by U.S. private equity firm, Bain Capital, worth $18 billion.

The deal initially was to be completed by the end of March, but it was delayed due to a prolonged review by Chinese antitrust authorities. The deal was approved by China last month.

Last year the Bain consortium which includes South Korean chipmaker SK Hynix, Apple Inc, Dell Technologies,Seagate Technologies and Kingston Technology won the battle for Toshiba Memory, which is the world’s 2 producer of NAND chips. Furthermore, under the deal with Bain, Toshiba repurchased 40% of the unit.
