Lease Commitments

We lease properties and equipment for use in our operations. In addition to rent, the leases may require us to pay directly for taxes, insurance, maintenance and other operating expenses or to pay higher rent when operating expenses increase. Rental expense, net of sublease income, was $233 million in 2013, $301 million in 2012 and $378 million in 2011.
The future minimum rental commitments under non-cancelable operating leases follow:
