During 2013, the Company recognized impairment charges of $29 million associated with its indefinite-lived tradename and IPR&D assets in the Company's CATD segment. Additionally, the Company recognized a $13 million impairment charge primarily associated with customer relationship intangible assets. See Note 9 for further details discussing these charges. The gross carrying amounts and related accumulated amortization amounts for these impairment charges were written off accordingly.

Amortization expense was $79 million, $88 million and $93 million during fiscal years 2013, 2012 and 2011, respectively. The following table presents expected future amortization expense including amortization expense of expected indefinite-lived IPR&D amortization based on anticipated regulatory product approvals. Actual amounts of amortization expense may differ due to actual timing of regulatory approvals, additional intangible assets acquired and foreign currency translation impacts (in millions):
