Unisys Corp is expected to give its defence systems arm a separate board in what is seen as preparation for sale of the business: it may also seek to liquidate the assets of its Unisys Finance Corp, which leases its products and has $684m of debt that is carried on the parent company’s books; the total debt at Unisys amounts to some $3,500m; Unisys intends to retain the unit but lay off the financing with banks and insurance companies.
