We are a party from time to time to various general and professional liability claims and lawsuits asserted against the lessees or borrowers of our properties, which in our opinion are not singularly or in the aggregate material to our results of operations or financial condition. These types of claims and lawsuits may include matters involving general or professional liability, which we believe under applicable legal principles are not our responsibility as a non-possessory landlord or mortgage holder. We believe that these matters are the responsibility of our lessees and borrowers pursuant to general legal principles and pursuant to insurance and indemnification provisions in the applicable leases or mortgages. We intend to continue to vigorously defend such claims.
