Commitments

Our operating leases primarily consist of ground leases on which certain of our facilities or other related property reside along with corporate office and equipment leases. These ground leases are long-term leases (almost all having terms for approximately 50 years or more), some contain escalation provisions and one contains a purchase option. Properties subject to these ground leases are subleased to our tenants. Lease and rental expense (which is recorded on the straight-line method) for 2013, 2012 and 2011, respectively, were $2,304,461, $2,195,835, and $1,994,565, which was offset by sublease rental income of $512,503, $492,095, and $443,829 for 2013, 2012, and 2011, respectively.

Fixed minimum payments due under operating leases with non-cancelable terms of more than one year at December 31, 2013 are as follows: (amounts in thousands)

2014	$	2,471
2015		2,644
2016		2,659
2017		2,620
2018		2,614
Thereafter		37,213
	$	50,221

The total amount to be received in the future from non-cancellable subleases at December 31, 2013, is $30.1 million.

Contingencies

We are a party to various legal proceedings incidental to our business. In the opinion of management, after consultation with legal counsel, the ultimate liability, if any, with respect to those proceedings is not presently expected to materially affect our financial position, results of operations or cash flows.
