How to find preferred dividends with just these:

Net sales $
COGS $
Operating Expenses $
Dividends to Common Stockholders $
Stock price per share (Mkt Price) $
Average Shares Outstanding #
Total Assets $
Total Liabilities $

I'm guessing it's something to so with common dividends, stock price, and shares outstanding. But I just can't wrap my brain around it. In the end I'm trying to find Earnings per share. But first I need the preferred dividends.

Thank you!
