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. The table above includes, as of
April 29, 2017,
purchased IP
not
yet deployed of
$0.8
million, which represents our share of the cost incurred in connection with the collaborative arrangement discussed in Note
11.
 
As part of our restructuring plan as discussed in Note
7,
we recorded an impairment charge of
$3.0
million for purchased IP
not
yet deployed for the
three
months ended
April 29, 2017.
