Goodwill and Other Intangible Assets |
A summary of changes in Quanta’s goodwill is as follows (in thousands):
The purchase price allocation adjustments recorded in the year ended December 31, 2015 resulted primarily from net working capital adjustments and changes in tax estimates. The goodwill impairment in the year ended December 31, 2015 primarily resulted from lower forecasted oil and gas services revenues for Quanta’s Gulf of Mexico operations and certain operations in Australia, due to the extended low commodity price environment. The two reporting units impacted are in Quanta’s Oil and Gas Infrastructure Services Division. Also, as described in Note 2, Quanta’s operating units are organized into one of Quanta’s two internal divisions and, accordingly, the goodwill associated with its operating units has been aggregated on a divisional basis and reported in the table above. These divisions are closely aligned with Quanta’s reportable segments and are based on the predominant type of work performed by each operating unit. From time to time, operating units may be reorganized between these internal divisions as business environments evolve.

Additionally, during the year ended December 31, 2015, Quanta recorded an impairment charge of $12.1 million related to customer relationships, trade names and non-compete agreement intangible assets. These intangible asset impairments primarily resulted from lower forecasted oil and gas services revenues for Quanta’s Gulf of Mexico operations and certain operations in Australia, due to the extended low commodity price environment. The two reporting units impacted are in Quanta’s Oil and Gas Infrastructure Services Division. The impairment charge is reflected in the December 31, 2015 accumulated amortization balances above.
