Acquired intangible assets represent intangible assets acquired through business combinations. Purchased intellectual property (“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 IP 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 IP is incorporated.

As part of our restructuring plan as discussed in Note

we recorded an impairment charge for purchased IP of

$3.0

million for the

three

months ended

April 29, 2017.
