13 Aug 2019debt financing● NeutralMajor

By this amendment the exchange offers no longer depended on the Anadarko merger: the completion-of-merger condition was struck out, leaving only effectiveness of the registration statement as an unwaivable condition. It also recorded that on 8 August Occidental had issued $13.0 billion of senior unsecured notes, raising about $12.9 billion after fees, to pay for the acquisition -- so the debt was already on the balance sheet before the legacy bonds were swapped. The tender deadline moved from 5:00 p.m. to 12:01 a.m.
