[1] During the nine months ended August 1, 2015, the Company acquired $52.3 million of intangible assets related to the Company’s acquisition of two businesses. See Note 3, “Acquisitions and Divestitures,” of the Notes to Condensed Consolidated Financial Statements.

[2] During the nine months ended August 1, 2015, the Company purchased a perpetual, non-exclusive license to certain patents for $7.8 million.

[3] The patent portfolio license was assigned an estimated useful life that reflects the Company’s consumption of the expected defensive benefits related to this license to certain patents. The method of amortization for the patent portfolio license reflects the Company’s estimate of the pattern in which these expected defensive benefits will be used by the Company and is primarily due to a mix of expiration patterns of the individual patents included in the license.
