6. Goodwill and Other Intangible Assets Goodwill was $44,620 and $41,148 as of September 30, 2012 and 2011, respectively. The increase in goodwill was due to a $1,712 correction discussed in Note 1, The components of other intangible assets are as follows: related to the calculation of foreign deferred tax liabilities associated with our fiscal 2009 acquisition of Epoch, and to $1,760 in foreign exchange fluctuations of the New Taiwan dollar.

In fiscal 2012, we acquired $155 in other intangible assets, and other intangible assets increased by $553 due to foreign exchange fluctuations of the New Taiwan dollar. In fiscal 2011, other intangible assets increased by $275 due to foreign exchange fluctuations of the New Taiwan dollar. Goodwill and indefinite-lived intangible assets are tested for impairment annually in the fourth fiscal quarter or more frequently if indicators of potential impairment exist, using a fair-value-based approach. The recoverability of goodwill is measured at the reporting unit level, which is defined as either an operating segment or one level below an operating segment. We have consistently determined the fair value of our reporting units using a discounted cash flow analysis (“step one”) of our projected future results. As discussed in Note 2 under the heading “Effects of Recent Accounting Pronouncements”, effective September 30, 2011, we adopted new accounting pronouncements related to our goodwill impairment analysis, which allows an entity to perform a “step zero” assessment of the fair value of their reporting units. We used this new guidance in our annual impairment analysis for goodwill in both fiscal 2012 and 2011. As also discussed in Note 2, in fiscal 2012, we adopted new accounting pronouncements related to our impairment review of indefinitelived intangible assets, which allows a qualitative assessment of factors used in the impairment review. Changes in economic and operating conditions that occur after the annual impairment analysis or an interim impairment analysis that impact our assumptions may result in future impairment charges. As a result of the review performed in the fourth quarter of fiscal 2012, we determined that there was no impairment of our goodwill and intangible assets as of September 30, 2012. Amortization expense was $2,682, $2,720 and $2,426 for fiscal 2012, 2011 and 2010, respectively. Estimated future amortization expense for the five succeeding fiscal years is as follows: Fiscal Year 2013 2014 2015 2016 2017 Estimated Amortization Expense $2,637 2,510 2,442 2,020 1,187 7. Other Long-Term Assets Other long-term assets consisted of the following: September 30, 2012 Auction rate securities Other long-term assets Other long-term investments Total $ 7,991 2,872 1,082 $ 11,945 2011 $ 8,041 1,504 827 $ 10,372 As discussed in Note 3 of this Form 10-K, the two ARS that we owned as of September 30, 2012 are classified as long-term investments. The securities are credit enhanced with bond insurance to an AA- credit rating and all interest payments continue to be received on a timely basis. Although we believe these securities will ultimately be collected in full, we believe that it is not likely that we will be able to monetize the securities in 47
