Schedule of future amortization expense

The following table shows the expected future amortization expense for our acquired intangible assets at October 31, 2022. Amortization of purchased technology is charged to amortization of acquired technology in our condensed consolidated statements of operations. Amortization of other acquired intangible assets such as customer lists is charged to amortization of other acquired intangible assets in our condensed consolidated statements of operations. If impairment events occur, they could accelerate the timing of acquired intangible asset charges.
