Leases

We have operating leases primarily associated with our corporate offices and regional service centers as well as for certain equipment. Our leases have remaining lease terms of

years, some of which include options, at our discretion, to extend the leases for additional periods generally on

one

-year revolving periods. Other leases allow for us to terminate the lease based on appropriate notification periods. For certain of our leased offices, we sublease a portion of the unoccupied space. The terms of the sublease arrangement generally coincide with the underlying lease.
