The following is a reconciliation between basic and diluted weighted average shares outstanding:

	For the Years Ended
	February 2,		February 3,		January 28,
(In thousands, except per share amounts)	2019		2018		2017
Weighted average common shares outstanding:
Basic number of common shares outstanding		176,476		177,938		181,429
Dilutive effect of stock options and non-vested restricted stock		1,559		2,218		2,406
Diluted number of common shares outstanding		178,035		180,156		183,835

There were no anti-dilutive stock options outstanding during Fiscal 2018. Stock option awards to purchase approximately 2.2 million and 2.2 million shares of common stock during Fiscal 2017 and Fiscal 2016, respectively, were outstanding, but were not included in the computation of weighted average diluted common share amounts as the effect of doing so would have been anti-dilutive.

Additionally, approximately 0.2 million, 19,000, and 24,000 shares of restricted stock units for Fiscal 2018, Fiscal 2017 and Fiscal 2016, respectively, were outstanding, but not included in the computation of weighted average diluted common share amounts as the effect of doing so would be anti-dilutive. Furthermore, approximately 0.2 million, 0.9 million, and 0.1 million of performance-based restricted stock awards for Fiscal 2018, Fiscal 2017, and Fiscal 2016, respectively, were not included in the computation of weighted average diluted common share amounts because the number of shares ultimately issued is contingent on the Company’s performance compared to pre-established performance goals.
