Commitments and Contingencies Disclosure [Abstract]

At December 31, 2018, we had 14 outstanding letter of credit obligations totaling $50,805,000 and expiring between 2019 and 2024. At December 31, 2018, we had outstanding construction in process of $194,365,000 for leased properties and were committed to providing additional funds of approximately $436,984,000 to complete construction. Purchase obligations at December 31, 2018, include $1,250,000,000 representing a definitive agreement to acquire outpatient medical facilities in 2019. Purchase obligations also include contingent purchase obligations totaling $17,309,000. These contingent purchase obligations relate to unfunded capital improvement obligations and contingent obligations on acquisitions. Rents due from the tenant are increased to reflect the additional investment in the property. During the year ended December 31, 2017, we finalized an agreement with the University of Toledo Foundation to transfer our corporate headquarters as a gift and recognized an expense of $40,730,000.

We evaluate our leases for operating versus capital lease treatment in accordance with ASC 840. A lease is classified as a capital lease if it provides for transfer of ownership of the leased asset at the end of the lease term, contains a bargain purchase option, has a lease term greater than 75% of the economic life of the leased asset, or if the net present value of the future minimum lease payments are in excess of 90% of the fair value of the leased asset. Certain leases contain bargain purchase options and have been classified as capital leases. At December 31, 2018, we had operating lease obligations of $1,138,046,000 relating to certain ground leases and company office space. Regarding the ground leases, we have sublease agreements with certain of our operators that require the operators to reimburse us for our monthly operating lease obligations. At December 31, 2018, aggregate future minimum rentals to be received under these noncancelable subleases totaled $72,789,000.

At December 31, 2018, future minimum lease payments due under operating and capital leases are as follows (in thousands):
