Item 8.01                                           Other Events.

As a result of the removal, without cause, on March 25, 2014 of all of the trustees of CommonWealth REIT, or CWH, CWH underwent a change in control, as defined in the shareholders agreement among us, CWH, the other shareholders of Affiliates Insurance Company, or AIC, an Indiana insurance company, and AIC. As a result of that change in control and in accordance with the terms of the shareholders agreement, we and the other non-CWH shareholders exercised our rights to purchase shares of AIC that CWH then owned.  Pursuant to that exercise, on May 9, 2014, we and those other shareholders purchased pro rata the AIC shares CWH owned.  In accordance with that exercise, we purchased 2,857 AIC shares from CWH for $825,093.  Following these purchases, we and the other remaining six shareholders (Reit Management & Research LLC, which provides us with management services, and five other companies to which Reit Management & Research LLC also provides management services) each own approximately 14.3% of AIC.  We and the other shareholders of AIC have purchased property insurance coverage pursuant to an insurance program arranged by AIC and with respect to which AIC is a reinsurer of certain coverage amounts.

For further information about our relationships with AIC and other relationships we have with certain of the other shareholders of AIC and related person transactions, please see Note 9 to our condensed consolidated financial statements included in Part I, Item 1 of our Quarterly Report on Form 10-Q for the quarter ended September 30, 2013, or our Quarterly Report.  In addition, for more information about these transactions and relationships, please see elsewhere in our Quarterly Report, including “Warning Concerning Forward Looking Statements” in Part I, and Amendment No. 1 to our Annual Report on Form 10-K for the year ended December 31, 2012, or our Amended Annual Report, our definitive Proxy Statement for the Annual Meeting of Stockholders held on May 16, 2013, or our Proxy Statement, our Current Report on Form 8-K dated September 19, 2013, and our other filings with the Securities and Exchange Commission, or SEC, including Note 15 to our consolidated financial statements included in our Amended Annual Report, the sections captioned “Business,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Related Person Transactions” and “Warning Concerning Forward Looking Statements” of our Amended Annual Report and the section captioned “Related Person Transactions and Company Review of Such Transactions” and the information regarding our Directors and executive officers in our Proxy Statement.  In addition, please see the section captioned “Risk Factors” of our Amended Annual Report for a description of risks that may arise as a result of these and other related person transactions and relationships.  Our filings with the SEC, including our Quarterly Report, our Amended Annual Report and our Proxy Statement, are available at the SEC’s website at www.sec.gov.  Copies of certain of our agreements with these related parties, including our shareholders agreement with AIC and its shareholders, are publicly available as exhibits to our public filings with the SEC and accessible at the SEC’s website.
