Basic earnings per ordinary share is computed by dividing reported net income by the weighted-average number of ordinary shares outstanding during each period. Diluted earnings per ordinary share is computed by calculating the effect of potential dilutive ordinary shares outstanding during the period using the treasury stock method. Dilutive ordinary equivalent shares consist of restricted share units and performance share units. Earnings per ordinary share was calculated as follows:


	Three Months Ended				Nine Months Ended
(amount in thousands except per share amounts)	March 27, 2020		March 29, 2019		March 27, 2020		March 29, 2019

Net income attributable to shareholders	$	28,267	$	28,635	$	85,455	$	87,998


Weighted-average number of ordinary shares outstanding (thousands of shares)		36,987		36,891		36,970		36,786
Incremental shares arising from the assumed vesting of restricted share units and performance share units (thousands of shares)		810		648		726		597

Weighted-average number of ordinary shares for diluted earnings per ordinary share (thousands of shares)		37,797		37,539		37,696		37,383


Basic earnings per ordinary share	$	0.76	$	0.78	$	2.31	$	2.39
Diluted earnings per ordinary share	$	0.75	$	0.76	$	2.27	$	2.35
Outstanding performance share units excluded from the computation of diluted earnings per ordinary share (thousands of shares) (1)		50		401		50		401

(1)	These performance share units were not included in the computation of diluted earnings per ordinary share because they are not expected to vest based on the Company’s current assessment of the related performance obligations.
