The following table shows how we reconcile our net income and the number of shares used in computing basic and diluted net income per share:
(in millions, except per share amounts)202420232022
Basic net income per share:
Consolidated net income $369.9 $141.1 $70.5 
Weighted average common shares outstanding42.8 42.6 42.6 
Basic net income per share$8.64 $3.31 $1.65 
Diluted net income per share:
Consolidated net income$369.9 $141.1 $70.5 
Weighted average common shares outstanding42.8 42.6 42.6 
Net effect of dilutive stock awards0.3 0.3 0.3 
Weighted average common shares outstanding for computing diluted income per share43.1 42.9 42.9 
Diluted net income per share$8.58 $3.29 $1.64 

During the periods presented, we have outstanding restricted stock units (RSUs), market stock units (MSUs), and performance stock units (PSUs) that are excluded from our calculation of diluted earnings per share as their effect is antidilutive. The amount of these potential antidilutive shares was immaterial.
