Citigroup (C) and Apollo Global Management (APO) are offering a private staple financing option for prospective buyers of Boeing's (BA) Jeppesen navigation unit, Bloomberg reported late Thursday, citing sources familiar with the matter.

The option would be the first private staple financing, which is a pre-arranged financing package offered to potential bidders for an acquisition, the report said.

The acquisition could be worth $7 billion, with debt financing ranging from $3 billion to $3.5 billion, the report said.

Talks are still ongoing, and the deal's terms and financing may change, the report said.

A Boeing representative told Bloomberg the company "does not comment on market rumors or speculation."

Citigroup and Apollo did not immediately reply to a request for comment from MT Newswires.
