This may be the related statement from Cavium's annual report:

"In November 2016, the Company entered into an asset purchase agreement with a third party company. Pursuant to the asset purchase agreement, the Company acquired property and equipment of $9.2 million and IPR&D of $2.0 million. The IPR&D was recorded at its relative fair using the multi-period excess earnings valuation approach and was written off immediately as the asset had no alternative future use."
