NOTE 6: DEFERRED CONTRACT COSTS
Some of the Companys client contracts require significant investment in the early stages which is expected to be recovered through billings over the life of the respective contracts. These contracts often involve the construction of new computer systems and communications networks and the development and deployment of new technologies. Substantial performance risk exists in each contract with these characteristics, and some or all elements of service delivery under these contracts are dependent upon successful completion of the development, construction and deployment phases. At June 30, 2008, approximately $650 million of the Companys net deferred construct and set-up costs related to contracts with active construct activities. The Company has approximately 25 active construct contracts with deferred costs in excess of $1 million. Some of these contracts have experienced delays in their development and construction phases, and certain milestones have been missed. It is reasonably possible that deferred costs associated with one or more of these contracts could become impaired due to changes in estimates of future contract cash flows.
