We perform our annual impairment testing on October 1, or more frequently, if events and circumstances indicate impairment may have occurred. As discussed in Note 2, "Summary of Significant Accounting Policies," we have the option to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit is less than the carrying value. During our annual impairment testing on October 1, we opted to perform a quantitative assessment where the fair value of each reporting unit was estimated using a discounted cash flow model combined with market valuation approaches. We assigned a weighting of 50% to the discounted cash flow analysis, 40% to the public company approach and 10% to the transaction approach for the year ended December 31, 2012. In certain instances, there was no weighting assigned to the transaction approach due to a lack of comparable market data and a weighting of 50% was assigned to the public company approach for those impacted reporting units. There was no impairment of goodwill as a result of our annual goodwill impairment test in 2012. We also did not encounter any events or changes in circumstances that indicated an impairment was more likely than not during interim periods in 2012. As of October 1, 2012, the fair value exceeded the carrying value by a significant margin for the 23 reporting units with a goodwill balance. During 2011 and 2010, the fair value of each reporting unit was estimated using a discounted cash flow model combined with market valuation approaches. We assigned a weighting of 50% to the discounted cash flow analysis and 50% to the public company approach for the year ended December 31, 2011. There was no weighting assigned to the transaction approach due to the lack of comparable market data in 2011. We assigned a weighting of 50% to the discounted cash flow analysis, 40% to the public company approach and 10% to the transaction approach for the year ended December 31, 2010. We recorded a goodwill impairment of $57.3 million during 2011 related to four reporting units serving the Virginia, Maryland and North Carolina markets. During 2010, we recorded a goodwill impairment of $5.7 million related to our Delaware location, which is included in discontinued operations. There are significant inherent uncertainties and management judgment involved in estimating the fair value of each reporting unit. While we believe we have made reasonable estimates and assumptions to estimate the fair value of our reporting units, it is possible that a material change could occur. If actual results are not consistent with our current estimates and assumptions, or the current economic downturn worsens or the projected recovery is significantly delayed beyond our projections, goodwill impairment charges may be recorded in future periods. Identifiable Intangible Assets, Net Identifiable intangible assets consist of the following (dollars in thousands):

The amounts attributable to customer relationships, noncompete agreements and tradenames are being amortized to "Selling, General and Administrative Expenses" on a pattern of economic benefit or a straight-line method over periods from two to twenty-five years. The amounts attributable to backlog are being amortized to "Cost of Services" on a proportionate method over the remaining backlog period. Amortization expense for the years ended December 31, 2012, 2011 and 2010 was $8.8 million, $7.1 million and $5.8 million, respectively. At December 31, 2012, future amortization expense of identifiable intangible assets is as follows (in thousands):
