Additional information, corporation pid dividends of $3.15 per share during the year. Company's common stock had a market price of $63 per share on June 30, and there was no change in the number of outstanding shares of common stock during the fiscal year.

My answer is:

I used the formula:
Net income - preferred dividends/average number of common shares outstanding
Net income (105,000), since there was no preferred shares, no deductions from the net income. The next step was to divide by average # common shares outstanding(100,000), and I came up with $1.05

$105,000/$100,000=$1.05 (earnings per share)

Did I calculate this correctly?
