(a)	Technology-based intangible assets included $128 million and $116 million as of March 31, 2016 and June 30, 2015, respectively, of net carrying amount of software to be sold, leased, or otherwise marketed.

Intangible assets amortization expense was $249 million and $740 million for the three and nine months ended March 31, 2016, respectively, and $361 million and $1.1 billion for the three and nine months ended March 31, 2015, respectively. Amortization of capitalized software was $18 million and $55 million for the three and nine months ended March 31, 2016, respectively, and $13 million and $68 million for the three and nine months ended March 31, 2015, respectively.

In the third quarter of fiscal year 2016, we corrected our intangible assets in the table above for a $585 million misstatement between gross carrying amount and accumulated amortization as of June 30, 2015. We do not consider this correction to be material, and there was no impact to our consolidated financial statements.

The following table outlines the estimated future amortization expense related to intangible assets held as of March 31, 2016:
