The computation of basic net income per share is based on the number of weighted average shares outstanding during the period. The computation of diluted net income per share includes the dilutive effect of share equivalents consisting of incremental shares deemed outstanding from the assumed exercise of options and unvested restricted stock units ("RSUs"). Performance share awards ("PSAs") are included in the computation of diluted net income per share only to the extent that the underlying performance conditions are satisfied prior to the end of the reporting period or would be satisfied if the end of the reporting period were the end of the related performance period, and if the effect would be dilutive.

A reconciliation of the numerators and denominators of the basic and diluted net income per share calculations is as follows (in thousands, except per share amounts):


	Thirteen weeks ended
	March 31, 2024		April 2, 2023
Basic net income per share:
Net income	$	114,100	$	76,160
Weighted average shares outstanding - basic	101,071		103,827
Basic net income per share	$	1.13	$	0.73
Diluted net income per share:
Net income	$	114,100	$	76,160
Weighted average shares outstanding - basic	101,071		103,827
Dilutive effect of share-based awards:
Assumed exercise of options to purchase shares	404		395
RSUs	549		481
PSAs	—		173
Weighted average shares and equivalent shares outstanding - diluted	102,024		104,876
Diluted net income per share	$	1.12	$	0.73

For the thirteen weeks ended March 31, 2024, the Company had 0.1 million options, 0.3 million RSUs and 0.4 million PSAs outstanding which were excluded from the computation of diluted net income per share as those awards would have been antidilutive or were performance awards with performance conditions not yet deemed met. For the thirteen weeks ended April 2, 2023, the Company had 0.4 million options, 0.4 million RSUs and 0.5 million PSAs outstanding which were excluded from the computation of diluted net income per share as those awards would have been antidilutive or were performance awards with performance conditions not yet deemed met.
