Acquired Intangible Assets

5. Acquired Intangible Assets

The Company amortizes intangible assets, which consist of purchased technologies that have estimated useful lives ranging from 7 to 10 years, using the straight-line method when the consumption pattern of the asset is not apparent. The Company reviews such assets for impairment whenever an impairment indicator exists and continually monitors events and changes in circumstances that could indicate carrying amounts of the intangible assets may not be recoverable. When such events or changes in circumstances occur, the Company assesses recoverability by determining whether the carrying value of such assets exceed the estimates of future undiscounted future cash flows expected to be generated by such assets. Should impairment exist, the impairment loss would be measured based on the excess carrying value of the asset over the asset’s estimated fair value. There was no impairment of intangible assets recorded for the three months ended March 31, 2016 and 2015. The weighted average remaining useful life of the Company’s acquired technology intangible assets is 6 years as of March 31, 2016.
