In May 2013, the Company entered into a new 12.5 year lease agreement for office space in Houston, Texas under the terms of an operating lease, with the lease commencing on or after March 1, 2015, and with minimum contractual obligations of approximately $104 million in the aggregate. We will amortize the total payments required under the lease agreement on a straight-line basis over the term of the lease.

We had no other material changes in our contractual commitments and obligations from the amounts referenced under Note 5 of our consolidated financial statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2012.
