9. Commitments and Contingencies Operating Leases We lease our facilities and certain equipment under non-cancelable operating leases, some of which contain renewal options, escalation clauses and requirements to pay other fees associated with the leases. We recognize rent expense on a straight-line basis. Two of our campus properties are leased from a related party. In December 2012, we entered into amended lease agreements for certain buildings on our Phoenix, Arizona campus which extended the lease term to December 31, 2022. The future minimum lease payments under the amended lease agreements are $0.5 million, $0.7 million, $0.7 million, $0.8 million, $0.8 million, and $4.5 million for the years ended September 30, 2013, 2014, 2015, 2016, 2017 and thereafter, respectively.
