The information appearing on Equity Commonwealth’s (“EQC”) website may contain forward looking statements and information within the meaning of the federal securities laws. Any forward looking statements contained on EQC’s website, including in filings with the Securities and Exchange Commission (“SEC”) posted on EQC’s website, are intended to be made pursuant to the safe harbor provisions of Section 21E of the Private Securities Litigation Reform Act of 1995. These statements are based on current expectations, estimates, projections and assumptions made by management. While EQC management believes the assumptions underlying its forward looking statements are reasonable, such information is inherently subject to uncertainties and may involve certain risks. Such forward looking statements are subject to risk and uncertainties, which could cause actual results, performance, or achievements of EQC to differ materially from anticipated future results, performance or achievements expressed or implied by such forward looking statements. Other risks and uncertainties are described under the heading “Risk Factors” in our Annual Report on Form 10-K and subsequent periodic reports filed with the SEC, which are available on the SEC’s website at www.sec.gov and are also accessible on EQC’s website at SEC Filings. Many of these uncertainties and risks are difficult to predict and beyond management’s control. Forward looking statements are not guarantees of future performance, results or events. EQC assumes no obligation to update or supplement forward looking statements due to subsequent events.
