RESTRUCTURING CHARGES AND IMPAIRMENT LOSSES [Abstract]
Description of assets subject to impairment	During each of the periods presented, the Company evaluated the recoverability of its leasehold improvement assets at certain delivery centers. An asset is considered to be impaired when the anticipated undiscounted future cash flows of its asset group are estimated to be less than the asset group’s carrying value. The amount of impairment recognized is the difference between the carrying value of the asset group and its fair value. To determine fair value, the Company used Level 3 inputs in its discounted cash flows analysis. Assumptions included the amount and timing of estimated future cash flows and assumed discount rates. During the three and nine months ended September 30, 2014, the Company recognized no losses related to leasehold improvement assets. During the three and nine months ended September 30, 2013, the Company recognized zero and $0.1 million, respectively, of losses related to leasehold improvement assets in the CMS segment.
