| Description of goodwill impairment charge | During fiscal 2015, we recorded a $186 million goodwill impairment loss to our hardware products reporting unit. We considered several approaches to determine the fair value of our hardware products reporting unit as of March 1, 2015 and concluded the most appropriate to be the income approach. The fair value of our hardware products reporting unit pursuant to the income approach was impacted by lower forecasted operating results for this reporting unit, primarily caused by lower forecasted revenues and our continued investment in hardware products research and development activities. We compared the implied fair value of goodwill in our hardware products reporting unit to its carrying value, which resulted in the $186 million goodwill impairment loss and represented the aggregate amount of goodwill for our hardware products reporting unit. The aggregate hardware products reporting unit goodwill that was impaired in fiscal 2015 resulted from our acquisitions of Pillar Data Systems, Inc., Xsigo Systems, Inc., GreenBytes, Inc. and MICROS Systems, Inc. Such impairment loss was recorded to acquisition related and other expenses in our fiscal 2015 consolidated statement of operations. We did not recognize any goodwill impairment losses in fiscal 2016 or fiscal 2014. | ||||||||||
