This Amendment No. 3 to Schedule 13D (this “Amendment No. 3”) relates to the common shares of beneficial interest, par value $0.01 per share (the “Shares”), of CommonWealth REIT, a Maryland real investment trust (the “Issuer” or “CommonWealth”) and amends the Schedule 13D filed on February 26, 2013, as amended by Amendment No. 1 thereto, filed with the SEC on February 27, 2013, and Amendment No. 2 thereto, filed with the SEC on March 4, 2013 (the “Original Schedule 13D” and, together with this Amendment No. 3, the “Schedule 13D”). Capitalized terms used and not defined in this Amendment No. 3 have the meanings set forth in the Original Schedule 13D.

This Amendment No. 3 is being filed by (i) Corvex Management LP, a Delaware limited partnership (“Corvex”), and Keith Meister and (ii) Related Fund Management, LLC, a Delaware limited liability company (“Related”), Related Real Estate Recovery Fund GP-A, LLC, a Delaware limited liability company, Related Real Estate Recovery Fund GP, L.P., a Delaware limited partnership, and Related Real Estate Recovery Fund, L.P., a Delaware limited partnership.

This Amendment No. 3 is being filed to amend Item 4 of the Schedule 13D as follows:

Item 4

Purpose of Transaction

Item 4 of the Schedule 13D is amended by adding the following:

As previously disclosed, on March 1, 2013 Corvex and Related filed a Complaint (No. 1:13-cv-10475) in the United States District Court of Massachusetts naming CommonWealth, Barry M. Portnoy, Adam D. Portnoy, Joseph L. Morea, William A. Lamkin and Frederick N. Zeytoonjian as defendants. The Complaint asked the Court to declare the defendants in violation of anti-fraud provisions of the Securities Exchange Act of 1934 and to enjoin the closing of CommonWealth’s equity offering. As part of their Complaint, Corvex and Related asked that the Court grant a temporary restraining order to prevent completion of the equity offering. On March 4, 2013, the Court held a hearing on the request for a temporary restraining order and related matters. At the hearing, Corvex and Related affirmed their desire to seek to replace all of the members of CommonWealth’s Board of Trustees. Later that day, the Court issued a ruling denying the request for a temporary restraining order. The Court has not yet reached a final decision on aspects of the Complaint beyond the request for the temporary restraining order.
