Intangible Assets

Indefinite-lived intangible assets are tested and reviewed annually for impairment during the fourth quarter or whenever there is a significant change in events or circumstances that indicate that the fair value of the asset may be less than the carrying amount of the asset. All other intangible assets with finite useful lives are being amortized on a straight-line basis over their estimated useful lives.

The following table sets forth the gross amount and accumulated amortization of the Company's intangible assets at June 28, 2014 and December 28, 2013:



In thousands	June 28, 2014			December 28, 2013

Total net finite-lived intangible assets	156,647			134,487
Tradenames (indefinite-lived)	34,912			34,912
Total	$	191,559		$	169,399

As of June 28, 2014, the Company had recorded intangible assets of $191.6 million, which includes amounts associated with loan acquisition costs. These expenditures represent the cost of obtaining financings that are capitalized in the balance sheet and amortized over the term of the loans to which such costs relate.
