As of December 31, 2018, approximately 70% of our consolidated Property and equipment, net held by Encompass Health Corporation and its guarantor subsidiaries was pledged to the lenders under our credit agreement. See Note 9, Long-term Debt, and Note 20, Condensed Consolidating Financial Information.

In February 2016, we entered into a development/lease agreement with CR HQ, LLC (the “Developer”) to construct our new home office in Birmingham, Alabama. Under the terms of this agreement, the Developer is responsible for all costs of constructing the new facility ‘shell’ which is being leased to us for an initial term of 15 years with four, five-year renewal options. The lease commenced in April of 2018. We were responsible for the costs associated with improvements to the interior of the building. Due to the nature and extent of the tenant improvements we made to the new home office and certain provisions of the development/lease agreement, we were deemed to be the accounting owner of the new home office during the construction period. Construction commenced in the second quarter of 2016. As of December 31, 2018 and 2017, Property and equipment, net includes $55.0 million and $49.8 million, respectively, for the construction costs incurred by the Developer, and Long-term debt, net of current portion includes a corresponding financing obligation liability of $54.8 million and $49.5 million, respectively. The remaining corresponding financing obligation liability of $0.2 million and $0.3 million as of December 31, 2018 and 2017 is included in the Current portion of long-term debt. The amounts recorded for construction costs and the corresponding liability are noncash activities for purposes of our consolidated statement of cash flows. See Note 9, Long-term Debt.

Leases—

We lease certain land, buildings, and equipment under noncancelable operating leases generally expiring at various dates through 2037. We also lease certain buildings and equipment under capital leases generally expiring at various dates through 2037. Operating leases generally have 1- to 20-year terms, with one or more renewal options, with terms to be negotiated at the time of renewal. Various facility leases include provisions for rent escalation to recognize increased operating costs or require us to pay certain maintenance and utility costs. Contingent rents are included in rent expense in the year incurred.

Some facilities are subleased to other parties. Rental income from subleases approximated $3.0 million, $2.9 million, and $4.1 million for the years ended December 31, 2018, 2017, and 2016, respectively. Total expected future minimum rentals under these noncancelable subleases approximated $2.6 million as of December 31, 2018.

Certain leases contain annual escalation clauses based on changes in the Consumer Price Index while others have fixed escalation terms. The excess of cumulative rent expense (recognized on a straight-line basis) over cumulative rent payments made on leases with fixed escalation terms is recognized as straight-line rental accrual and is included in Other long-term liabilities in the accompanying consolidated balance sheets, as follows (in millions):



	As of December 31,
	2018		2017
Straight-line rental accrual	$	12.1	$	11.2

Future minimum lease payments at December 31, 2018, for those leases having an initial or remaining noncancelable lease term in excess of one year, are as follows (in millions):

In addition to the above, and as discussed in Note 9, Long-term Debt, “Other Notes Payable,” we have three sale/leaseback transactions involving real estate accounted for as financings. Future minimum payments, two of which are accounted for as interest, under these obligations are $7.5 million in year one, $7.5 million in year two, $7.6 million in year three, $7.5 million in year four, $6.8 million in year five, and $82.2 million thereafter.
