York assets started the year with $110,000-$60,000= $50,000 net assets. So for the current year, the revenues were $110,000 and expenses were $50,000 so add $110,000 to the $50,000 = $160,000 - $50,000= $110,000 net for this year. Since the total dividends are $45,000 then $45,000/$110,000= %40.9 increase in the stockholder's equity for the year which is very good.
