18. OPERATING LEASES

We lease certain properties and equipment with lease terms expiring through 2038. In most instances, the property leases provide for the renegotiation of rental terms at fixed intervals, and generally contain renewal options for periods ranging from five to 15 years.

Net rent expense for all operating leases for the years ended December 31, 2013, 2012 and 2011 is summarized as follows:

	Year Ended December 31,
