Goodwill and Intangible Assets Disclosure [Abstract] |
Goodwill and other intangibles | 6. Goodwill and other intangibles Goodwill is not amortized, but is reviewed annually or more frequently if indicators arise, for impairment. The Company’s evaluation of goodwill impairment involves first assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit, as defined below, is less than its carrying amount. The Company may bypass this qualitative assessment, or determine that based on its qualitative assessment considering the totality of events and circumstances (including macroeconomic factors, industry and market considerations, current and projected financial performance, a sustained decrease in share price, or other factors), that additional impairment analysis is necessary. This additional analysis involves comparing the Company’s market capitalization relative to the carrying value of its equity and other factors deemed appropriate by management annually, as of October 1. However, actual fair values that could be realized in a transaction may differ from those used to evaluate the potential impairment of goodwill. Goodwill was evaluated for impairment at the reporting unit level, which was defined as the operating segment level. At December 31, 2015 and 2014, goodwill recorded on the Company’s consolidated balance sheet was $41,466,000 and $23,546,000, respectively. The Company’s fair value measurement test, performed annually as of October 1, revealed no indications of impairment as of the respective balance sheet dates. The activity in the Company’s goodwill as of December 31 was as follows:
|  | 2015 |  |  | 2014 |
Balance at beginning of year |  | $ | 23,546 |  |  | $ | — |
Acquisitions |  |  | 17,920 |  |  |  | 23,546 |
Balance at end of year |  | $ | 41,466 |  |  | $ | 23,546 |
Management reviews other intangible assets, which include backlog, customer relationships, developed technology and trade names and trademarks, for impairment when events or changes in circumstances indicate the carrying amount of the asset may not be recoverable. In the event that impairment indicators exist, a further analysis is performed and if the sum of the expected undiscounted future cash flows resulting from the use of the asset were less than the carrying amount of the asset, an impairment loss equal to the excess of the asset’s carrying value over its fair value would be recorded. Management considers historical experience and all available information at the time the estimates of future cash flows are made, however, the actual cash values that could be realized may differ from those that are estimated. For the year ended December 31, 2015 and 2014, there were no indications of impairment. Amortization expense was classified as follows in the Company’s consolidated statements of operations for the years ended December 31:
|  | 2015 |  |  | 2014 |  |  | 2013 |
Cost of sales |  | $ | 742 |  |  | $ | 1,134 |  |  | $ | 40 |
Operating expenses |  |  | 4,582 |  |  |  | 1,013 |  |  |  | — |
|  | $ | 5,324 |  |  | $ | 2,147 |  |  | $ | 40 |
The tables below shows the amortization period and intangible asset cost by intangible asset as of December 31, 2015 and December 31, 2014 and the accumulated amortization and net intangible asset value in total for all those intangible assets that related to the Company’s acquisitions, for the related period. Refer to Note 3, “Acquisitions” for a further discussion of these acquisitions.

The weighted average useful life of those intangibles acquired and included in the table above was approximately 13 years as of December 31, 2015 and 2014. The table below shows the estimated future amortization expense for intangible assets:
