The following table shows the cost, accumulated amortization, and weighted-average life in years for our acquired intangible assets at the dates indicated. The weighted-average lives are calculated for assets that are not fully amortized.

The following table shows the expected future amortization expense for our acquired intangible assets at October 31, 2024. 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.
