Certain Obligations, Liabilities and Litigation

We may be subject to various obligations, liabilities and litigation assumed in connection with or arising out of our acquisitions or otherwise arising in connection with our business. Some of these liabilities may be indemnified by third parties. However, if these liabilities are greater than expected or were not known to us at the time of acquisition, if we are not entitled to indemnification, or if the responsible third party fails to indemnify us for these liabilities, such obligations, liabilities and litigation could have a Material Adverse Effect on us. In addition, in connection with the sale or leasing of our properties, we may incur various obligations and liabilities, including indemnification obligations, relating to the operations of those properties, which could have a Material Adverse Effect on us.

Other

We are subject to certain operating and ground lease obligations that generally require fixed monthly or annual rent payments and may also include escalation clauses and renewal options. These leases have terms that expire during the next 88 years, excluding extension options. Our future minimum lease obligations under non-cancelable operating and ground leases as of December 31, 2012 were $29.7 million in 2013, $29.4 million in 2014, $27.6 million in 2015, $23.7 million in 2016, $16.8 million in 2017, and $426.4 million thereafter.
