Intangible assets impaired includes purchased software licenses to be sold to others. This amount was expensed as part of cost of revenues in the Consolidated Statement of Operations.

Intangible assets of our international subsidiaries are recorded in their respective functional currency; therefore, the carrying amounts and accumulated amortization of intangible assets increase or decrease, with a corresponding change in accumulated OCI, due to changes in foreign currency exchange rates. Amortization expense is scheduled to decrease in future periods.

Estimated future annual amortization expense is as follows:
