Acquired intangible assets represent intangible assets acquired through business combinations. Purchased intellectual property (“Purchased IP”) represents intangible assets acquired through direct purchases of licensed technology from vendors which is incorporated into our products.

Purchased IP – not yet deployed relates to Purchased IP from third parties for our products that are currently in development. We begin amortizing such intellectual property upon the earlier of the beginning of the term of the license agreement, as appropriate, or at the time we begin shipment of the associated products into which such intellectual property is incorporated.

The following table presents the amortization of intangible assets in the accompanying condensed consolidated statements of operations (in thousands):
