Caledonia’s basic EPS = (net income − preferred stock dividends) / (weighted average common shares outstanding)
= [$460,000 − ($1,000 × 1,000 × 0.08)] / 2,300,000 = $0.17.
Using the treasury stock method, if the warrants were exercised, cash inflow would be 10,000 × 100 × $1.50 = $1,500,000. The number of Caledonia shares that could be purchased with the inflow, using the average share price, is $1,500,000 / $2 = 750,000. The net increase in common shares outstanding would have been 1,000,000 − 750,000 = 250,000.
Diluted EPS = $380,000 / (2,300,000 + 250,000) = $0.15.
