Business Segment Information

11. Business Segment Information

        The accounting policies of the Company's segments are the same as those described in Note 1—"General." The Company evaluates performance of its segments based on income before income taxes, before stock compensation expense, depreciation and amortization, interest expense, interest income, gain on sale of assets, and special charges or benefits ("Segment Profit"). Management uses Segment Profit information for internal reporting and control purposes and considers it important in making decisions regarding the allocation of capital and other resources, risk assessment and employee compensation, among other matters. Effective September 1, 2010, Public Sector has subcontracted with Pharmacy to provide pharmacy benefits management services on a risk basis for one of Public Sector's customers. As such, revenue and cost of care related to this intersegment arrangement are eliminated. The Company's segments are defined previously. The following tables summarize, for the periods indicated, operating results by business segment (in thousands):

(1)

Stock compensation expense is included in direct service costs and other operating expenses, however this amount is excluded from the computation of segment profit since it is managed on a consolidated basis.

(2)

Identifiable assets by business segment are those assets that are used in the operations of each segment. The remainder of the Company's assets cannot be specifically identified by segment.
