CommonWealth REIT (NYSE:CWH) responded to the announcement that Sam Zell and David Helfand have been enlisted by Related Fund Management LLC and Corvex Management LP (“Related/Corvex”). Adam Portnoy, President and Managing Trustee of CWH, said: “The announcement by Related/Corvex that Mr. Zell may serve as Chairman and Mr. Helfand may serve as CEO of CWH is an obvious attempt to divert shareholder attention from Related’s abysmal historical track record of operating public real estate companies. I am surprised that Mr. Zell and Mr. Helfand have joined the efforts by Related/Corvex in their pursuit of full control of CWH without first approaching CWH to fully understand the Company’s business plan and the Board’s commitment to governance enhancements. The track record of Related’s principals when they have controlled publicly owned real estate companies is certainly not in keeping with the public company governance principles that Mr. Zell has espoused. I also hope that Messrs. Zell and Helfand will be more transparent than Related/Corvex have been to date about agreements and understandings that may affect CWH, including those concerning possible future compensation from CWH and their reported option agreement to purchase $90 million of CWH common shares from Related/Corvex.” “Although Corvex/Related have identified a handpicked slate of Trustees that will implement their plan to take control of CWH without paying other shareholders a premium, CWH shareholders should be aware that there is not a Trustee election taking place at this time. Related/Corvex are acting as though they can disregard the processes intended to ensure that all CWH shareholders have a voice.” CommonWealth REIT is a real estate investment trust that primarily owns office properties in central business district locations throughout the U.S. CWH is headquartered in Newton, MA.
