Ground Lease Modification, net

In May 2014, the Company modified the ground leases and property operating agreements of five on-campus medical office buildings, totaling 424,000 square feet, associated with the sponsoring health system. The Company paid the health system $12.0 million to modify these agreements and eliminate exercisable purchase options that would have resulted in a purchase price below estimated fair market value. This modification payment will be amortized over the remaining term of the in-place ground leases on a straight-line basis.
