Interests in the existing Seadrill common shares were extinguished under the plan of reorganization contemplated by the RSA. The plan provided holders of Seadrill Common stock with 2% of new Seadrill equity, subject to dilution by the primary structuring fee and an employee incentive plan. The RSA contemplated certain releases and exculpations and implementation of a customary equity-based employee incentive plan at the effective date.
