Goodwill is recognized net of accumulated impairment losses of $255,530,000 and $150,965,000 as of December 31, 2014 and 2013, respectively. Annual Impairment Testing The Company performed its annual goodwill impairment test as of October 31, 2014, 2013, and 2012. During 2014 and 2012, the Company incurred impairment charges as a result of the October 31 annual tests. The impairment charges recognized in 2013 resulted from the interim test performed during the third quarter. No additional impairment charges were incurred as of the annual test in 2013. During the October 31, 2014 impairment test, the Company examined all eleven reporting units identified for review. Step one of the impairment test consists of comparing the fair value of a reporting unit with its carrying amount including goodwill. The fair value of each reporting unit was determined using two valuation techniques: an income approach and a market approach. Each valuation approach relies on significant assumptions including a weighted average cost of capital (WACC). The WACC is calculated based upon the capital structure of market participants in the Company’s peer group. Other assumptions used to calculate fair value for each reporting unit include projected revenue growth, forecasted cash flows, and earnings multiples based on the market value of the Company and market participants within its peer group. The following table summarizes the WACC calculation ranges used during the annual goodwill impairment tests performed during 2014 and 2013:
Date of Impairment Test |  | WACC
October 31, 2014 |  | 12.9% to 13.6%
October 31, 2013 |  | 11.1% to 12.7%
During our 2014 and 2012 annual goodwill impairment tests, we identified reporting units with carrying values in excess of fair value due to decreased revenue projections. Therefore, the Company initiated step two of the goodwill impairment test which involved calculating the implied fair value of goodwill by allocating the fair value of the reporting unit to the fair value of its assets and liabilities other than goodwill, calculating an implied fair value of goodwill, and comparing the implied fair value to the carrying amount of goodwill. As a result of step two of the annual goodwill impairment test, the Company estimated that the implied fair value of goodwill for the reporting units was less than their carrying values by $104,565,000 and $4,328,000 for the years ended December 31, 2014 and 2012, respectively, which have been recorded as impairment charges. Interim Impairment Testing We test goodwill and indefinite-lived intangible assets for impairment on an annual basis as of October 31 and at interim dates when indicators of impairment are present. During the third quarter of 2013, we significantly revised our forecast to reflect lower revenue and operating margin expectations for the Company in 2013. As a result, we concluded there was an indicator of impairment requiring an interim impairment test for four of our reporting units, two within the Residential Products segment and two within the Industrial and Infrastructure Products segment. In 2014 and 2012, no indicators of impairment were identified as of interim dates; therefore, no interim tests were performed. The 2013 interim impairment test used similar valuation methodology as used during the annual tests (income and market approaches), and WACC calculation employed in the interim test. The Company based the WACC on similar market participants used in the interim test. Other assumptions used in the multiples approach such as projected revenue growth and forecasted cash flows for the Company’s reporting units were also similar to those used during the interim test. A third party projection of peer companies’ earnings multiples, projected revenue growth, and forecasted cash flows were obtained for the analysis as well. Of the four reporting units identified during the 2013 interim test, one of the reporting units in the Industrial and Infrastructure Products segment, and the Company’s sole business in Europe, had a carrying value in excess of the fair value due to decreased revenue projections, affected by recessionary economic conditions. Therefore, the Company initiated step two of the goodwill impairment test which involved calculating the implied fair value of goodwill by allocating the fair value of the reporting unit to the fair value of its assets and liabilities other than goodwill, calculating an implied fair value of goodwill, and comparing the implied fair value to the carrying amount of goodwill. As a result of step two of the goodwill impairment test, the Company estimated that the implied fair value of goodwill for the reporting unit was less than its carrying value by $21,040,000, for which an impairment charge was recorded as of September 30, 2013. Acquired Intangible Assets Acquired intangible assets consist of the following (in thousands):

The Company recognized impairment charges related to indefinite lived trademark intangible assets as well as for other definite lived intangible assets for the year ended December 31, 2014. Impairment charges were also recognized for indefinite lived trademark intangible assets for the years ended December 31, 2013 and 2012. The impairment charges related to the trademarks were recognized as a result of the Company’s impairment test of indefinite-lived intangibles. The fair values of the impaired trademarks were determined using an income approach consisting of the relief-from-royalty method. The impairment charges related to the definite-lived intangibles were recognized as a result of the estimated future discounted cash flows of the asset being less than its carrying value. The fair value of the impaired definite-lived intangibles was determined using an income approach consisting of either the relief-from-royalty method or the excess earnings method. In addition, the Company recognized amortization expense related to the acquired intangible assets. The following table summarizes the impairment charges for the years ended December 31 (in thousands):
| 2014 |  | 2013 |  | 2012
Residential Products | $ | 1,200 |  |  | $ | 1,454 |  |  | $ | 300 |

Impairment charges | $ | 3,405 |  |  | $ | 2,454 |  |  | $ | 300 |
