Doors basic earnings per share (EPS) was ($372,000 / 100,000 =) $3.72. If the bonds were converted, interest payments would not have been made. Net income is increased by the interest paid on the bonds net of taxes: $372,000 + (($1000 × 2,000 × 0.06) × (1 − 0.40)) = $444,000.
Diluted EPS was $444,000 / (100,000 + (2,000 × 25)) = $2.96.
