(Reuters) - Office supplies retailer Staples Inc (>> Staples, Inc.) is willing to sell more assets to win antitrust approval for its $6.3 billion takeover of Office Depot Inc (>> Office Depot Inc), Bloomberg reported on Thursday, citing two people familiar with the matter.

Under the deal announced in February, Staples had offered to divest about half of Office Depot's assets with revenues of up to $1.25 billion. In talks with the FTC, the company has already offered to divest assets worth half that amount, one of the sources told Bloomberg.

Staples said earlier this month it would transfer contracts to retailer Essendant Inc (>> Essendant Inc) to ease anti-trust concerns.

The company could offer to transfer more contracts to Essendant to satisfy antitrust concerns, Bloomberg said.

The FTC has been intensely scrutinizing the merger that will unite the two biggest office supply retailers in the United States. (http://bit.ly/1XqZF9E)
