New major risk - Revenue and earnings growth Earnings have declined by 29% per year over the past 5 years. This is considered a major risk. Ultimately, shareholders want to see a good return on their investment and that generally comes from sharing in the company's profits.

In addition, if the company pays dividends it will also likely need to reduce or cut them, striking a dual blow to total shareholder returns.
