Schedule of Acquired Finite-Lived Intangible Assets by Major Class [Table Text Block]

As a result of our acquisitions and purchases of licensed technology and patents, identified intangible assets recorded for each period and their respective estimated weighted average useful lives were as follows:

	December 31, 2016			December 26, 2015
	Gross Assets (In Millions)		Estimated Useful Life (In Years)	Gross Assets (In Millions)		Estimated Useful Life (In Years)
Acquisition-related developed technology	$	5,842	9	$	238	6
Acquisition-related customer relationships	$	1,148	12	$	110	11
Acquisition-related brands	$	87	6	$	—	n/a

Schedule Of Useful Life Ranges For Identified Intangible Assets [Table Text Block]

As of December 31, 2016, the estimated useful life of our acquisition-related brands is six years. The estimated useful life ranges for substantially all other identified intangible assets that are subject to amortization were as follows:

(In Years)	Estimated Useful Life Range
Acquisition-related developed technology	4	–	9
Acquisition-related customer relationships	6	–	12
Licensed technology and patents	2	–	17
