Goodwill And Other Intangible Assets
GOODWILL AND OTHER INTANGIBLE ASSETS
As discussed in Note 13 to the Consolidated Financial Statements, effective in the third quarter of 2014, the Company completed a realignment of resources and management toward a new organizational structure comprised of a single operating segment, which combined its existing Implantable Electronic Systems Division and Cardiovascular and Ablation Technologies Division. This change resulted in the combination of the Company’s reporting units. See Note 11 for further information on the reporting unit change and its impact to the Company's goodwill impairment testing.
The changes in the carrying amount of goodwill for the fiscal years ended January 3, 2015 and December 28, 2013 were as follows (in millions):

During 2014, CardioMEMS received FDA approval of its CardioMEMS™ (Heart Failure) HF System. As a result of the approval, the Company reclassified $63 million of acquired IPR&D from an indefinite-lived intangible asset to a purchased technology definite-lived intangible asset, and began amortizing the intangible asset over its estimated useful life of 11 years. Additionally, the Company received FDA approval of the TactiCath® irrigated ablation catheter during 2014 and reclassified $33 million of acquired IPR&D from an indefinite-lived intangible asset to a purchased technology definite-lived intangible asset, and began amortizing the intangible asset over its estimated useful life of 7 years.

During 2014, the Company also recognized impairment charges of $50 million and $8 million related to certain indefinite-lived IPR&D intangible assets and a tradename intangible asset, respectively, as the fair values decreased below their carrying values. The gross carrying amounts for these impairment charges were written down accordingly. See Note 8 and Note 11 for further information on the impairment charges.

During 2013, the Company recognized impairment charges of $15 million and $14 million associated with certain indefinite-lived IPR&D and tradename assets, respectively, as the fair values decreased below their carrying values. Additionally, the Company recognized a $13 million impairment charge primarily associated with customer relationship intangible assets. The gross carrying amounts were written down accordingly. See Note 8 and 11 for further details discussing these charges.

The following table presents expected future amortization expense for acquired intangible assets recognized as of January 3, 2015 and expected amortization expense of indefinite-lived IPR&D assets based on anticipated regulatory product approvals (in millions):

The expected amortization expense is an estimate. Actual amounts of amortization expense may differ due to actual timing of regulatory approvals, additional intangible assets acquired, foreign currency translation impacts, impairment of intangible assets and other events. The Company expenses the costs incurred to renew or extend the term of intangible assets.
