Concord Corporation had net income of $270000 and paid dividends of $400000 to common stockholders and $10000 to preferred stockholders in 2020. Concord Corporation's common stockholders' equity at the beginning and end of 2020 was $830000 and $1170000, respectively. There are 93000 weighted-average shares of common stock outstanding.

I know ROE is divide net income by shareholders equity.

270000/ ???

I am really struggling with the dividends and I have zero help from my professor and textbook.
