The following table presents a reconciliation of the weighted average shares outstanding used in calculating basic and diluted net income (loss) per share as well as the calculation of basic and diluted net income (loss) per share:

  

Three Months Ended June 30,

  

Six Months Ended June 30,

 
      

As Restated

     

As Restated

 
(in thousands, except per share amounts) 2020  2019  2020  2019 

Numerator (basic and diluted)

                
Net income (loss) allocated to common shareholders for basic calculation $3,405  $(24,242) $(61,965) $(86,712)

Denominator

                

Weighted average common shares outstanding, basic

  45,620   46,824   45,570   46,762 

Dilutive effect of RSUs and 2.75% Convertible Notes (1),(2)

  661   —   —   — 

Weighted average common shares outstanding, diluted

  46,281   46,824   45,570   46,762 
Net income (loss) per share, basic $0.07  $(0.52) $(1.36) $(1.85)
Net income (loss) per share, diluted $0.07  $(0.52) $(1.36) $(1.85)

(1) Due to the net loss, RSUs representing approximately 552,000 for the six months ended June 30, 2020, and RSUs representing approximately 375,000 and 398,000 for the three and six months ended June 30, 2019, respectively, have been excluded from the number of shares used in calculating diluted net loss per share, as their inclusion would be antidilutive. 

(2) As the average price of our common stock was below $31.47 per share since the issuance date of the 2.75% Convertible Notes, the number of shares used in calculating diluted net loss per share for the three and six months ended June 30, 2020 excluded the potential dilution from the 2.75% Convertible Notes converting into shares of common stock.
