GOODWILL

Goodwill represents the premium paid over the fair value of the net tangible and intangible assets that are individually identified and separately recognized in business combinations. All of our goodwill as of September 30, 2016 and March 31, 2016 is related to our technology segment.

We test goodwill for impairment on an annual basis, as of the first day of our third fiscal quarter, and between annual tests if an event occurs, or circumstances change, that would more likely than not reduce the fair value of a reporting unit below its carrying amount.

OTHER INTANGIBLE ASSETS

Customer relationships and capitalized software development costs are amortized over an estimated useful life, which is generally between 3 to 7 years. Trade names and trademarks are amortized over an estimated useful life of 10 years.

Total amortization expense for other intangible assets was $1.1 million and $0.7 million for the three months and $2.2 million and $1.3 million for the six months ended September 30, 2016 and 2015, respectively.
