I wouldn't trust Yahoo Finance as far as I could throw them! I have seen them continue to list companies that are bankrupt, show officers that have left the company and moved elsewhere, and just keep old information without updates.
They almost never provide original information, stick to mostly boiler-plate, and rely on secondary sources for a good amount of their information. Even stuff like quarterly and annual financial information has been wrong. I prefer the SEC filings myself, or the PR and company information found on their own website.
