Acquisition [Abstract]
Acquisition	Note 2—Acquisition On May 1, 2009, we acquired essentially all of the assets of Contract Environmental Services, Inc. ("CES"), a South Carolina based corporation which is a provider of professional housekeeping, laundry and dietary department services to long-term care and related facilities. We believe the acquisition of CES expands and complements our position of being the largest provider of such services to long-term care and related facilities in the United States. The aggregate consideration was approximately $13,825,000 consisting of: (i) $4,613,000 in cash paid, (ii) issuance of approximately 99,000 shares of our common stock (valued at approximately $1,183,000) and future issuance of approximately 397,000 shares (valued at approximately $3,311,000) contingent upon the achievement of certain financial targets, and (iii) the repayment of approximately $4,718,000 of certain debt obligations of CES. The final allocation of such consideration resulted in our recording of the following: (i) approximately $8,998,000 of tangible assets consisting primarily of accounts receivable, (ii) $5,700,000 of amortizable intangible assets, (iii) $1,936,000 of goodwill, and (iv) current liabilities of approximately $2,809,000. The CES results of operations are not included in our consolidated results of operations before May 1, 2009, which was prior to the closing of the transaction. Effective January 1, 2010, all of CES' operations were fully integrated with our operations.
