We have an information management contract with HP Enterprise Services (“HPES”) which runs through 2014. Services provided under this contract include support for European mainframe system processing, as well as workplace, service desk and voice and data network management. We can terminate the contract for convenience without paying a termination fee by providing sixty days prior notice. Should we terminate the contract for convenience, we have an option to purchase the assets placed in service under the HPES contract. We also have several agreements for similar services with other third party providers. These contracts have various terms through 2016 and include desktop services, voice and data network related services, mainframe application, development and support and mid-range applications processing and support.
