Net Income Per Share:

The Company presents both basic and diluted net income per share on the face of the unaudited condensed consolidated statements of income. Basic net income per share is calculated by dividing net income by the weighted average number of shares outstanding during the period. Diluted net income per share is calculated by dividing net income by the weighted average diluted shares outstanding. Dilutive shares are computed using the treasury stock method for share-based awards. Performance-based restricted share units are included in diluted shares only if the related performance conditions are considered satisfied as of the end of the reporting period. Net income per share is calculated as follows (in thousands, except per share amounts):



	Fiscal three months ended						Fiscal three months ended
	September 29, 2018						September 30, 2017
	Income		Shares	Per Share Amount			Income		Shares	Per Share Amount
Basic net income per share:	$	116,784	121,876	$	0.96		$	91,896	126,416	$	0.73
