Expected future amortization expense for acquired intangible assets

The following table shows the expected future amortization expense for our acquired intangible assets at July 31, 2018. Amortization of purchased technology is charged to cost of service and other revenue and to amortization of acquired technology in our statements of operations. Amortization of other acquired intangible assets such as customer lists is charged to amortization of other acquired intangible assets in our statements of operations. If impairment events occur, they could accelerate the timing of acquired intangible asset charges.
