CommonWealth REIT (NYSE: CWH) today commented upon the results of a purported consent solicitation by Corvex Management LP (“Corvex”) and Related Fund Management, LLC (“Related” and together with Corvex, “Corvex/Related”): On April 12, 2013 Corvex/Related wrote to CWH demanding a record date for a consent solicitation to remove the entire CWH Board without cause. Because the demand letter did not comply with the requirements for a record date request established in CWH’s Bylaws, CWH responded to Corvex/Related by pointing out certain deficiencies and requesting additional information. Rather than attempting to comply with the governing Bylaws, Corvex/Related instead unilaterally declared a record date for shareholders to join their consent and began soliciting written consents as a so called “referendum”. After beginning to solicit CWH shareholders, Corvex/Related pursued its pending litigation against CWH in the Maryland Circuit Court by asking that Court to declare certain CWH Bylaws invalid. On May 8, 2013, the Maryland Circuit Court issued an Order upholding CWH’s arbitration Bylaw and referring all other matters in the litigation between CWH and Corvex/Related to arbitration under the auspices of the American Arbitration Association. Thereafter, Corvex/Related notified the Arbitration Panel and CWH that the time for delivery of written consents to their purported consent solicitation would close on June 18, 2013, and Corvex/Related requested the Arbitration Panel to set a hearing on their motion for partial summary judgment on certain issues relating to the consent solicitation. That hearing has been scheduled for July 26, 2013, but the timing of any ruling is at the discretion of the Arbitration Panel. At some time unknown to CWH, Corvex/Related notified Broadridge Financial Solutions that the time for delivery of written consents by shareholders as of the self-proclaimed record date would be extended to close on June 21, 2013. Then, on June 21, 2013, Corvex/Related delivered a letter to CWH and issued a press release claiming that it had received consents from over 70% of CWH’s shareholders and asserting that the CWH Trustees are removed from office. Neither the June 18 th or June 21 st date corresponds to any permitted solicitation period in CWH’s Bylaws. The Arbitration Panel that is considering the actions by Corvex/Related has not yet ruled.CWH continues to believe that the consent solicitation recently pursued by Corvex/Related has no legal effect. Since April 12, 2013, Corvex/Related have actively solicited CWH shareholders by mailing consent cards, issuing press releases and repeatedly making false and misleading statements about CWH and its manager, Reit Management & Research LLC. CWH also issued press releases and mailed letters in opposition to Corvex/Related activities, but CWH did not solicit written consent revocation cards. Accordingly, the Corvex/Related consent solicitation did not compete with a consent revocation solicitation. Also, CWH believes Corvex/Related set its self-proclaimed record date at a time when a large number of CWH’s shares appear to have been held by short term focused hedge funds. Based on the trading volume in CWH shares since the Corvex/Related self-proclaimed record date, CWH believes that a significant number of shareholders who joined the Corvex/Related consent solicitation have since sold their shares.
