Acquisitions [Text Block]	Acquisitions The company accounts for acquisitions using the acquisition method of accounting. The results of operations of acquisitions are included in the company's consolidated results from their respective dates of acquisition. The company allocates the purchase price of each acquisition to the tangible assets, liabilities, and identifiable intangible assets acquired based on their estimated fair values. In certain circumstances, a portion of purchase price may be contingent upon the achievement of certain operating results. The fair values assigned to identifiable intangible assets acquired and contingent consideration were determined primarily by using an income approach which was based on assumptions and estimates made by management. Significant assumptions utilized in the income approach were based on company specific information and projections, which are not observable in the market and are thus considered Level 3 measurements by authoritative guidance (see Note H). The excess of the purchase price over the fair value of the identified assets and liabilities has been recorded as goodwill. Any change in the estimated fair value of the net assets prior to the finalization of the allocation for acquisitions could change the amount of the purchase price allocable to goodwill. The company is not aware of any information that indicates the final purchase price allocations will differ materially from the preliminary estimates. 2013 Acquisition During the first six months of 2013, the company completed one acquisition. The aggregate consideration for this acquisition was $9,952 and included $570 of contingent consideration. The impact of this acquisition was not material to the company's consolidated financial position or results of operations. The pro forma impact of the 2013 acquisition on the consolidated results of operations of the company for the second quarter and first six months of 2013 and 2012 as though this acquisition occurred on January 1, 2012 was also not material. 2012 Acquisitions During 2012, the company completed seven acquisitions. The aggregate consideration for these seven acquisitions was $289,782, net of cash acquired and included $10,390 of contingent consideration. The impact of these acquisitions were not material, individually or in the aggregate, to the company's consolidated financial position or results of operations.
