The changes in the gross goodwill balance since June 30, 2012 resulted from foreign currency translation adjustments.
Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in each business combination. In September 2011, the FASB amended its guidance to simplify testing goodwill for impairment, allowing an entity to first assess qualitative factors to determine whether it is necessary to perform the two-step quantitative goodwill impairment test.
The Company has four reporting units: Defect Inspection, Metrology, Service and Other. As of December 31, 2012, substantially all of the goodwill balance resided in the Defect Inspection reporting unit.
The fair value of each of the Company's reporting units was substantially in excess of its estimated carrying amount as of the most recent quantitative analysis of goodwill impairment performed in the three months ended December 31, 2010. There have been no triggering events or changes in circumstances since that quantitative analysis to indicate that the fair value of any of the Company's reporting units would be less than its carrying amount.
The Company performed a qualitative assessment of the goodwill by reporting unit as of November 30, 2012 during the three months ended December 31, 2012 and concluded that it was more likely than not that the fair value of each of the reporting units exceeded its carrying amount. As a result of the Company's determination following its qualitative assessment, it was not necessary to perform the two-step goodwill impairment test at this time. In assessing the qualitative factors, the Company considered the impact of these key factors: change in industry and competitive environment, market capitalization, stock price, earnings multiples, budgeted-to-actual revenue performance from prior year, gross margin and cash flow from operating activities.
Based on the Company's assessment, goodwill in the reporting units was not impaired as of December 31, 2012 or 2011.

Intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable.
For the three months ended December 31, 2012 and 2011, amortization expense for other intangible assets was $4.6 million and $7.7 million, respectively. For the six months ended December 31, 2012 and 2011, amortization expense for other intangible assets was $11.8 million and $15.7 million, respectively. Based on the intangible assets recorded as of December 31, 2012, and assuming no subsequent additions to, or impairment of, the underlying assets, the remaining estimated amortization expense is expected to be as follows:
