The following table presents the computation of basic loss per share (in thousands, except per share amounts):



	Three Months Ended
	September 23, 2018			September 24, 2017
Net loss		($11,067	)		($19,857	)
Weighted average common shares	101,884			97,811
Basic loss per share		($0.11	)		($0.20	)

The following computation reconciles the differences between the basic and diluted loss per share presentations (in thousands, except per share amounts):



	Three Months Ended
	September 23, 2018			September 24, 2017
Net loss		($11,067	)		($19,857	)
Weighted average common shares - basic	101,884			97,811
Dilutive effect of stock options, nonvested shares and Employee Stock Purchase Plan purchase rights	—			—
Weighted average common shares - diluted	101,884			97,811
Diluted loss per share		($0.11	)		($0.20	)

Potential common shares that would have the effect of increasing diluted earnings per share or decreasing diluted loss per share are considered to be anti-dilutive and as such, these shares are not included in calculating diluted earnings per share. For the three months ended September 23, 2018, there were 2 million of potential common shares not included in the calculation of diluted loss per share because their effect was anti-dilutive. For the three months ended September 24, 2017, there were 10.1 million of potential common shares not included in the calculation of diluted loss per share because their effect was anti-dilutive.
