The increases in goodwill and intangible assets during the fiscal year ended September 30, 2011 resulted from the acquisitions, primarily SiGe, during the fiscal year ended September 30, 2011 as discussed in Note 3, Business Combinations. The Company tests its goodwill and non-amortizing trademarks for impairment annually as of the first day of its fourth fiscal quarter and in interim periods if certain events occur indicating that the carrying value of goodwill or non-amortizing trademarks may be impaired. The results of the annual impairment tests indicated that none of the goodwill or trademarks had been impaired during the year and as a result, step two was not performed. There were no other indicators of impairment noted during the fiscal year ended September 30, 2011. Annual amortization expense for the next five years related to intangible assets is expected to be as follows (in thousands):
| 2012 |  | 2013 |  | 2014 |  | 2015 |  | 2016
Amortization expense | $ | 25,599 |  |  | $ | 19,810 |  |  | $ | 15,211 |  |  | $ | 13,172 |  |  | $ | 9,147 |
The increase in amortization expense during the fiscal year ended September 30, 2011 relates to the identifiable assets acquired as part of the business combinations noted in Note 3, Business Combinations.
