(1) The weighted-average amortization period for acquired trade names excludes $48.7 million for acquired trade names recorded in connection with the LoopNet acquisition on April 30, 2012, which amount is not amortized, but is subject to annual impairment tests.

In February 2015, as a result of the Company's product development efforts, it launched a new Apartments.com website with a cleaner look, information about actual rental availabilities, rents and other fees, and better search functionality. In conjunction with the launch, the Company ceased using the database technology acquired in the acquisition of the Apartments.com Business. The Company evaluated the acquired developed technology for impairment during the first quarter of 2015 and determined that the carrying value of the acquired developed technology was impaired as the Company had ceased using the asset. The Company recorded an impairment charge of approximately $1.4 million in cost of revenues in the condensed consolidated statements of operations within the Company's North America operating segment for the three months ended March 31, 2015.
