Commitments and Contingencies Disclosure [Abstract]

Schedule of future minimum lease payments for leases

Estimated minimum future lease payments (excluding common area maintenance charges) include payments for certain renewal periods at our option because failure to renew results in an economic disincentive due to significant capital expenditure costs (e.g., racking structures), thereby making it reasonably assured that we will renew the lease. Such payments in effect at December 31, are as follows:

Year	Operating Lease Payment		Sublease Income			Capital Leases
2016	$	220,357	$	(4,827	)	$	56,543
2017	208,975		(4,354		)	49,217
2018	196,632		(3,316		)	39,696
2019	184,157		(2,864		)	31,909
2020	171,794		(2,922		)	24,418
Thereafter	1,046,705		(10,327		)	134,532
Total minimum lease payments	$	2,028,620	$	(28,610	)	336,315
