Goodwill arises from the purchase price for acquired businesses exceeding the fair value of tangible and intangible assets acquired less assumed liabilities and non-controlling interests. Management assesses the goodwill of each of its reporting units for impairment at least annually at the beginning of the fourth quarter and as “triggering” events occur that indicate that it is more likely than not that an impairment exists. The Company’s most recent annual impairment test was performed as of the first day of the Company’s fiscal fourth quarter of 2012 and no impairment was identified. There have been no "triggering" events which indicate a potential impairment in 2013. Reporting units resulting from recent acquisitions generally present the highest risk of impairment. Management believes the impairment risk associated with these reporting units typically decreases as such businesses are integrated into the Company and positioned for improved future earnings growth. In measuring the fair value of its reporting units, management relies on a number of factors including operating results, business plans, economic projections, anticipated future cash flows and transactions and market-place data. The factors used by management in its impairment analysis are inherently subject to uncertainty. While the Company believes it has made reasonable estimates and assumptions to calculate the fair value of its reporting units, if actual results are not consistent with management’s estimates and assumptions, goodwill may be overstated and a charge would need to be taken against net earnings.
