Note 10.    Leases

The Company leases certain facilities, computers, equipment and vehicles under various lease agreements generally over periods of one to twenty years. Under most arrangements, the Company pays the property taxes, insurance, maintenance and expenses related to the leased property. Many of the leases include provisions that enable the Company to renew the lease based upon fair value rental rates on the date of expiration of the initial lease.

As of August 31, 2011, future obligations under non-cancelable operating leases (related to continuing operations) were as follows: $22.2 million in fiscal 2012; $18.1 million in fiscal 2013; $14.6 million in fiscal 2014; $10.9 million in fiscal 2015; $8.4 million in fiscal 2016; and $31.4 million thereafter. Total rental expense under operating leases was $26.4 million, $22.3 million and $28.8 million in fiscal 2011, 2010 and 2009, respectively. As discussed in Note 17, "Contingencies and Litigation" the Company is also contingently liable for certain leases entered into by a former subsidiary.
