i have been looking all over the internet and i cant find anything/
any suggestions on where to look?
The reason you can not find them is because neither appears to have any preferred stock outstanding. Most companies do not. I checked the income statements on Yahoo finance and neither shows any preferred stock. yahoo might be incorrect. A more definitive source is the SEC filings. They are also found on Yahoo finance. Look for their 10k when you get there and look at their balance sheet. PEP did appear to have had some preferred stock in 2007 but it no longer shows.
yahoo finance is one source. If you search here in Answers, you will find that KO had no preferred stock as of 2007. Try a similar search for Pepsi.
