Item 1.01. Entry into a Material Definitive Agreement.

On August 24, 2011, Chesapeake Lodging Trust (the “Trust”) announced that it had entered into a definitive agreement to acquire the 613-room Denver Marriott City Center from WTCC City Center Investors V, L.L.C. for a purchase price of $119.0 million, plus customary pro-rated amounts and closing costs. The Trust intends to fund the acquisition with available cash on hand and by borrowing under its revolving credit facility. The Trust expects the acquisition will close within the next 30 days, subject to satisfaction of customary closing conditions. The Trust can give no assurance that the acquisition will be consummated during that time period, or at all. A copy of the Trust’s press release announcing this agreement is filed as Exhibit 99.1 to this report.

Certain statements and assumptions in this report contain or are based upon “forward-looking” information and are being made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are subject to risks and uncertainties. When we use the words “will likely result,” “ may,” “anticipate,” “estimate,” “should,” “expect,” “believe,” “intend,” or similar expressions, the Trust intends to identify forward-looking statements. Such forward-looking statements include, but are not limited to, the Trust’s expectations as to the expected mix of consideration to be paid and time for completing the acquisition. Such statements are subject to numerous assumptions and uncertainties, many of which are outside our control. The Trust undertakes no obligation to publicly release the result of any revisions to these forward-looking statements that may be made to reflect any future events or circumstances, except as required by law.
