GOODWILL AND OTHER INTANGIBLE ASSETS [Abstract]

5. GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill was $43,916 as of March 31, 2013, and $44,620 as of September 30, 2012. The decrease in goodwill was due to foreign exchange fluctuations of the New Taiwan dollar.

Goodwill and indefinite-lived intangible assets are tested for impairment annually in the fourth quarter of the fiscal year 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. Historically, we consistently determined the fair value of our reporting units using a discounted cash flow analysis ("step one") of our projected future results. Effective September 30, 2011, we adopted a new accounting pronouncement related to our goodwill impairment analysis, which allowed an entity to first perform a qualitative analysis ("step zero") of the fair value of its reporting units to determine whether it is necessary to perform the historical two-step quantitative goodwill analysis. We used this new guidance in our annual impairment analysis for goodwill in both fiscal 2012 and 2011, determining that it was more likely than not that the carrying amounts of all reporting units exceeded their respective fair values. The recoverability of indefinite-lived intangible assets was historically measured using the royalty savings method. In fiscal 2012, we adopted new accounting pronouncements related to our impairment review of indefinite-lived 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 these assumptions may result in future impairment charges.

We completed our annual impairment test during our fourth quarter of fiscal 2012 and concluded that no impairment existed. There were no indicators of potential impairment during the quarter ended March 31, 2013, so it was not necessary to perform an impairment review for goodwill and indefinite-lived intangible assets during the quarter. There have been no cumulative impairment charges recorded on the goodwill of any of our reporting units.

The components of other intangible assets are as follows:

	March 31, 2013				September 30, 2012
	Gross Carrying		Accumulated		Gross Carrying		Accumulated
	Amount		Amortization		Amount		Amortization
Other intangible assets subject to amortization:
Product technology	$	8,331	$	5,353	$	8,387	$	4,902
Acquired patents and licenses		8,270		6,985		8,270		6,775
Trade secrets and know-how		2,550		2,550		2,550		2,550
Distribution rights, customer lists and other		12,384		6,812		12,586		6,283

Total other intangible assets subject to amortization		31,535		21,700		31,793		20,510

Total other intangible assets not subject to amortization*		1,190				1,190

Total other intangible assets	$	32,725	$	21,700	$	32,983	$	20,510

* Total other intangible assets not subject to amortization consist primarily of trade names.

Amortization expense on our other intangible assets was $658 and $1,319 for the three and six months ended March 31, 2013, respectively. Amortization expense on our other intangible assets was $675 and $1,344 for the three and six months ended March 31, 2012, respectively. Estimated future amortization expense for the five succeeding fiscal years is as follows:

Fiscal Year	Estimated Amortization Expense
Remainder of 2013	$	1,303
2014		2,480
2015		2,412
2016		1,996
2017		1,166

- Definition

The entire disclosure for the aggregate amount of goodwill and a description of intangible assets, which may include (a) for amortizable intangible assets (also referred to as finite-lived intangible assets), the carrying amount, the amount of any significant residual value, and the weighted-average amortization period, (b) for intangible assets not subject to amortization (also referred to as indefinite-lived intangible assets), the carrying amount, and (c) the amount of research and development assets acquired and written off in the period, including the line item in the income statement in which the amounts written off are aggregated, if not readily apparent from the income statement. Also discloses (a) for amortizable intangibles assets in total and by major class, the gross carrying amount and accumulated amortization, the total amortization expense for the period, and the estimated aggregate amortization expense for each of the five succeeding fiscal years, (b) for intangible assets not subject to amortization the carrying amount in total and by major class, and (c) for goodwill, in total and for each reportable segment, the changes in the carrying amount of goodwill during the period (including the aggregate amount of goodwill acquired, the aggregate amount of impairment losses recognized, and the amount of goodwill included in the gain (loss) on disposal of a reporting unit). If any part of goodwill has not been allocated to a reportable segment, discloses the unallocated amount and the reasons for not allocating. For each impairment loss recognized related to an intangible asset (excluding goodwill), discloses: (a) a description of the impaired intangible asset and the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method for determining fair value, (c) the caption in the income statement or the statement of activities in which the impairment loss is aggregated, and (d) the segment in which the impaired intangible asset is reported. For each goodwill impairment loss recognized, discloses: (a) a description of the facts and circumstances leading to the impairment, (b) the amount of the impairment loss and the method of determining the fair value of the associated reporting unit, and (c) if a recognized impairment loss is an estimate not finalized and the reasons why the estimate is not final. May also disclose the nature and amount of any significant adjustments made to a previous estimate of an impairment loss.
