The transactions are expected to take the form of a tax-free distribution to RR Donnelley shareholders of at least 80% of the shares of common stock in Donnelley Financial Solutions and LSC Communications. Immediately following the completion of the transactions, existing RR Donnelley shareholders will own shares in all three companies. Donnelley Financial Solutions and LSC Communications each filed a Form 10 on March 31, 2016. Additionally, the expected leadership of the three companies was announced in the Company’s Form 8-K filed on April 13, 2016. The transactions are subject to customary conditions, including obtaining rulings from the Internal Revenue Service and/or tax opinions, execution of inter-company agreements and final approval by the Company’s Board of Directors. The Company expects to complete the transactions in October 2016, but there can be no assurance that the transactions will be completed on the anticipated timeline, or at all, or that the terms of the transactions will not change. Upon separation, the historical results of Donnelley Financial Solutions and LSC Communications will be presented as discontinued operations.
