14. EARNINGS (LOSS) PER SHARE (EPS)

We present EPS using the two-class method. This method allocates undistributed earnings between common shares and non-vested share-based payment awards that entitle the holder to non-forfeitable dividend rights. Our participating securities are our non-vested restricted stock units.

The following table sets forth the computation of our basic and diluted EPS available to shareholders of common stock (excluding participating securities):

(in millions, except per share data)
Numerator
Net income (loss)$35.0 $(33.6)$64.3

Denominators

Less: Weighted-average participating securities(4.2)(3.7)(4.9)
Weighted-average common shares outstanding117.5 116.6 114.5 
Effect of dilutive securities -
Dilutive stock-based compensation0.2 — 1.0 
Diluted shares outstanding -
Adjusted weighted-average shares after assumed conversions117.7 116.6 115.5 
Basic EPS$0.29 $(0.29)$0.54 
Diluted EPS$0.29 $(0.29)$0.53 
Basic and diluted loss per share are the same in 2023 because the effect of potentially dilutive stock-based compensation would have been antidilutive. Excluded potentially dilutive shares were 0.3 million in 2023.
