Most companies have an investor relations department. This method of assessing stocks is underused by most investors. These people get paid to answer your questions about their company. We highly recommend calling any company whose stock you'd like to purchase and ask any questions you have. You could also email them, but I think a phone call is much more valuable.
First check out their web site, to see if your questions are answered in a FAQ (Frequently Asked Question) page. Notice the quality of the web site. What do you think of it. The quality of this has some reflection on the quality of their other products.
The person you speak with can be an important indication of what the company is like. Each company has a corporate culture. Most companies hire similar types of people. The person you speak with was hired, by someone in the company, who was hired by someone who hired .... and was hired by the CEO. One of the most important parts of a company is their hiring practices. If this investor relation person is lousy, then the companies process to hire may be broken. You should consider it a negative, and find many more positives when purchasing their stock.
