This report contains certain forward-looking statements within the meaning of the federal securities laws. These forward-looking statements are generally identifiable by use of the words “will,” “believe,” “expect,” “intend,” “anticipate,” “estimate,” “project” or similar expressions, whether in the negative or affirmative. Forward-looking statements are based on management’s current expectations and assumptions and are not guarantees of future performance. Factors that may cause actual results to differ materially from current expectations include risks that the conditions to the settlement agreement may not be satisfied timely, or at all, and those risk factors and other factors discussed from time to time in our periodic filings with the Securities and Exchange Commission, including our Annual Report on Form 10-K for the year ended December 31, 2011. Accordingly, there is no assurance that our expectations will be realized. Except as otherwise required by the federal securities laws, we expressly disclaim any obligations or undertaking to publicly release any updates or revisions to any forward-looking statement contained in this report to reflect events, circumstances or changes in expectations after the date of this report.

ITEM 8.01. Other Events

On October 29, 2012, DiamondRock Hospitality Company (the “Company”) reached a settlement of the bankruptcy and related litigation involving the Allerton Hotel. The Company currently holds a senior mortgage loan secured by the Allerton Hotel. In exchange for resolving its objection to the plan of reorganization filed by affiliates of Petra Capital Management, DiamondRock will receive a $5.0 million cash payment and will restructure the debt it currently holds into a $66.0 million mortgage loan with a four year term (plus a one year extension option) bearing interest at 5.5%. The settlement, which has been approved by the United States Bankruptcy Court in the Northern District of Illinois, is subject to certain closing conditions. If these conditions are not met by January 18, 2013, including the $5.0 million cash payment, the Allerton Hotel will be sold pursuant to an auction in accordance with the Bankruptcy Code, in which case the Company would have a $71 million claim in the sale process.
