16. Operating segments

The Company discloses segment information as reflected in the management information systems reports that its chief operating decision maker uses in making decisions and to report certain entity-wide disclosures about products and services, major customers, and the countries in which the entity holds material assets or reports material revenues. A description of the Company's operating segments is contained in Note 23 to the Company's audited consolidated financial statements included in its Annual Report on Form 10-K for the year ended June 30, 2017.

The reconciliation of the reportable segments revenue to revenue from external customers for the three months ended March 31, 2018 and 2017, is as follows:

The Company does not allocate interest income, interest expense or income tax expense to its reportable segments. The Company evaluates segment performance based on segment operating income before acquisition-related intangible asset amortization which represents operating income before acquisition-related intangible asset amortization and allocation of expenses allocated to Corporate/Eliminations, all under GAAP.

The reconciliation of the reportable segments measure of profit or loss to income before income taxes for the three and nine months ended March 31, 2018 and 2017, is as follows:


		Three months ended						Nine months ended
		March 31,						March 31,
		2018			2017			2018			2017
Reportable segments measure of profit or loss	$	12,795		$	31,563		$	65,579		$	99,494
Operating income: Corporate/Eliminations		(5,231	)		(7,016	)		(16,702	)		(17,177	)
Interest income		5,154			5,124			14,903			14,489
Interest expense		(2,426	)		(467	)		(6,872	)		(1,773	)
Income before income taxes	$	10,292		$	29,204		$	56,908		$	95,033

The following tables summarize segment information that is prepared in accordance with GAAP for the three and nine months ended March 31, 2018 and 2017:

The segment information as reviewed by the chief operating decision maker does not include a measure of segment assets per segment as all of the significant assets are used in the operations of all, rather than any one, of the segments. The Company does not have dedicated assets assigned to a particular operating segment. Accordingly, it is not meaningful to attempt an arbitrary allocation and segment asset allocation is therefore not presented.

It is impractical to disclose revenues from external customers for each product and service or each group of similar products and services.
