Note M. Leases and Contingencies

The Company operates parking facilities under operating leases expiring on various dates, generally prior to 2020. Certain of the leases contain options to renew at the Company's discretion.

Total future annual rent expense is not determinable as a portion of such future rent is contingent based on revenues of the parking facilities. At December 31, 2013, the Company's minimum rental commitments, excluding contingent rent provisions under all non-cancellable operating leases, are as follows:


2014(1)	$	178,127
2015		129,447
2016		106,513
2017		86,711
2018		65,846
2019 and thereafter		232,340


	$	798,984

(1): $34,111 is included in 2014's minimum commitments for leases that expire in less than one year.

Rent expense, including contingent rents, was $326,814, $173,502 and $108,324 in 2013, 2012 and 2011, respectively. Contingent rent expense was $133,877, $79,552 and $58,309 in 2013, 2012 and 2011, respectively. Contingent rent expense consists primarily of percentage rent payments, which will cease at various times as certain leases expire.

The Company enters into contingent purchase price arrangements from time to time for its business combinations and depending upon the date of the business combination, some of its contingent purchase price arrangements are not reflected in its consolidated balance sheet as those acquisitions occurred prior to the adoption of the most recent guidance on business combinations which now requires these to be recorded at fair value on the date of the acquisition.

The Company accrued contingent payment obligations outstanding under the previous business combination accounting pronouncement of $254 and $255 (on an undiscounted basis), as of December 31, 2013 and 2012, respectively. Such contingent payments have been accounted for as additional purchase price as all performance criteria have been achieved for the respective year. Additionally. The Company has recorded a contingency obligation for acquisitions subsequent to the adoption of the most recent guidance on business combinations, in the amount of $1,537 and $3,324, as of December 31, 2013 and 2012, as of December 31,2013 and 2012, respectively.
