The following table presents goodwill balances and the movements for each of our reportable segments during the nine months ended July 31, 2018:

Goodwill as of July 31, 2018	$	801		$	1,611	$	521		$	2,933

In May 2018, we re-organized our operating segments and moved our microfluidics business from our life sciences and applied markets operating segment to our diagnostics and genomics operating segment. As a result, we reassigned approximately $45 million of goodwill from our life sciences and applied markets segment to our diagnostics and genomics segment using the relative fair value allocation approach. Goodwill balances as of October 31, 2017, have been recast to conform to this new presentation.
