New major risk - Financial position The company's debt is not well covered by operating cash flow. Operating cash flow to total debt ratio: 2.0% This is considered a major risk.

The company has less cash from operations to cover its expenses from servicing large debt and it increases the risk of liquidity issues. It also extends the time it would take for the company to pay back the debt in full, meaning it may not be able to easily pay it all off in a distress scenario.

New major risk - Revenue and earnings growth Earnings have declined by 62% 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. If profits are declining over an extended period, then in most cases the share price will decline over time unless the company can turn around its fortunes. A trend of falling earnings can be very difficult to turn around. If the company is well already established it may also be a sign the company has matured and is in decline. 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. This is currently the only risk that has been identified for the company. Duyuru • Mar 17
