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.

As of December 29, 2012, the Company had recorded intangible assets of $75.7 million. Included in this amount are loan acquisition costs incurred in association with the Merger. 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.

Amortization of intangible assets for the Successor was $8.6 million for the fiscal year ended December 29, 2012 and $8.0 million for the eleven months ended December 31, 2011, of which $2.7 million and $2.5 million were charged to Interest expense, respectively.
