Business Acquisitions, Goodwill and Intangible Assets |
Business Acquisitions, Goodwill and Intangible Assets | 4. Business Acquisitions, Goodwill and Intangible Assets Consideration for business acquisitions during the quarter ended December 31, 2012 totaled $54.3 million in cash and $14.3 million in stock. Business acquisitions included South Africa-based BKS Group and Asia-based KPK Quantity Surveyors. These business acquisitions did not meet the quantitative thresholds, either individually or in the aggregate, to require pro forma disclosures of operating results based on the Company’s consolidated assets and income. At the time of acquisition, the Company preliminarily estimates the amount of the identifiable intangible assets acquired based upon historical valuations of similar acquisitions and the facts and circumstances available at the time. The Company determines the final value of the identifiable intangible assets as soon as information is available, but not more than 12 months from the date of acquisition. Post-acquisition adjustments primarily relate to project related liabilities. The changes in the carrying value of goodwill by reportable segment for the three months ended December 31, 2012 and 2011 were as follows:
