On April 14, 2011, the board of directors of Warner Chilcott plc (the “Company”) approved a plan to restructure the Company’s operations in Belgium, the Netherlands, France, Germany, Italy, Spain, Switzerland and the United Kingdom. The restructuring will not impact the Company’s operations at its headquarters in Dublin, Ireland, its facilities in Dundalk, Ireland, Larne, Northern Ireland or Weiterstadt, Germany or its commercial operations in the United Kingdom. The Company determined to proceed with the restructuring following the completion of a strategic review of its operations in its Western European markets where its product ACTONEL (risedronate sodium) lost exclusivity in late 2010. ACTONEL accounted for approximately 70% of the Company’s Western European revenues in 2010. In connection with the restructuring, the Company intends to move to a wholesale distribution model in the affected jurisdictions to minimize operational costs going forward. The Company currently expects to complete the restructuring by the middle of 2012. The implementation of the restructuring plan is expected to impact approximately 500 employees and remains subject to consultation with local works councils in certain European jurisdictions.

In connection with the restructuring, the Company currently expects to record aggregate restructuring charges of approximately $120 to $130 million based on current exchange rates, consisting of approximately $115 to $125 million in employee severance charges and approximately $5 million as a result of lease and other contract terminations. All of these charges will result in future cash expenditures for the Company. The substantial majority of the restructuring charges are expected to be recognized in 2011 and relate to employee severance. Approximately $43 million in employee severance charges are expected to be recorded in the quarter ended March 31, 2011.

On April 14, 2011, the board of directors of the Company also approved the decision to repurpose its Manati, Puerto Rico manufacturing facility (the “Manati Facility”). As a result, the Company expects to record aggregate charges of approximately $33 million in the quarter ended March 31, 2011, consisting of approximately $26 million in non-cash charges resulting from the write-down of certain property, plant and equipment assets and approximately $7 million in employee severance charges. Going forward, the Manati Facility will primarily serve as a warehouse and distribution service center. Only the employee severance charge is expected to result in future cash expenditures for the Company.

The Company issued a press release announcing the Western European restructuring plan and repurposing of the Manati Facility on April 18, 2011. A copy of the Company’s press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated by reference herein.
