(12) LEASES

We lease office facilities for use in our operations, as well as transportation, computer and other equipment. We also have an office facility lease agreement with an entity in which an executive's father and brother have a 100% ownership interest. The executive does not have an interest in the entity that leases the property to us and the lease arrangement existed at the time we acquired the division that occupies this property. Most of our leases are non-cancelable operating lease agreements and they expire at various dates through 2018. In addition to rent, the leases generally require us to pay taxes, maintenance, insurance and certain other operating expenses.

Rent expense was approximately $5.9 million in 2011, $5.4 million in 2010, and $6.3 million in 2009, which included rent expense associated with related party lease agreements of $1.8 million in 2011, $1.9 million in 2010 and $2.0 million in 2009.
