Intangible Assets and Acquisition Related Charges

Intangible Assets and Acquisition Related Charges:

In connection with our acquisition of SiliconBlue in December 2011, we recorded identifiable intangible assets related to developed technology and customer relationships based on guidance for determining fair value under the provisions of ASC 820. The following table summarizes the details of the Company’s total purchased intangible assets (in thousands):

	Weighted Average Amortization Period  (in years)	Gross		Accumulated Amortization			Intangible assets, net of amortization  December 28, 2013
Developed technology	7	$	10,700	$	(3,121	)	$	7,579
Customer relationships	5.5	7,800		(2,895		)	4,905
Total	6.3	$	18,500	$	(6,016	)	$	12,484

Amortization expense associated with these intangible assets is reported as Acquisition related charges, including amortization of intangible assets in the Consolidated Statements of Operations and amounted to $2.9 million, $2.9 million, and $0.1 million in 2013, 2012, and 2011, respectively. We expect amortization expense related to these intangible assets to approximate $2.9 million in 2014, 2015 and 2016. We expect amortization expense related to these intangible assets to approximate $2.2 million in 2017 and $1.5 million in 2018.

Acquisition related charges, including amortization of intangible assets in the Consolidated Statements of Operations also include severance and professional fees related to the acquisition, as well as the amortization of the stepped up value of inventory collectively amounting to less than $0.1 million, $1.2 million, and $0.4 million in 2013, 2012, and 2011, respectively.
