Supervalu has completed the $3.3 billion sale of its largest grocery chains – including Jewel-Osco – to an investor group led by Ceberus Capital Management, the company said Thursday.

Eden Prairie, Minn.-based Supervalu also announced that Robert Miller, president and CEO of the Albertsons chain of grocery stores, will take over as non-executive chairman. He replaces former Supervalu CEO Wayne Sales, who will now serve as a director on the board.

In January, Supervalu struck a deal to sell its chains – Albertsons, Acme, Jewel-Osco and Shaw’s and Star Market stores – to the Ceberus Capital group.
