New major risk - Financial data availability The company's latest financial reports are more than a year old. Last reported fiscal period ended September 2013. This is considered a major risk. If the company has not reported its earnings on time, it may have been delayed due to audit problems or it may be finding it difficult to reconcile its accounts. In the worst case scenario, it may be facing other major going concern issues jeopardizing its viability as a listed company. Currently, the following risks have been identified for the company: Major Risk Latest financial reports are more than 1 year old (reported September 2013 fiscal period end). Minor Risk Market cap is less than US$100m (₩110.2b market cap, or US$79.5m). New Risk • Aug 24
New major risk - Revenue and earnings growth Earnings have declined by 26% 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. Currently, the following risks have been identified for the company: Major Risk Earnings have declined by 26% per year over the past 5 years. Minor Risk Market cap is less than US$100m (₩108.1b market cap, or US$78.2m). New Risk • Mar 28
New major risk - Earnings quality The company has a high level of non-cash earnings. Accrual ratio: 23% This is considered a major risk. Non-cash earnings can arise from many different things. However, if a company consistently has a high level of non-cash earnings, it may be a sign that they are recognizing revenue from customers before the full value of the sales are received as cash or they are not depreciating the value of their assets appropriately. These are practices that inflate earnings, while not providing a similar increase to cash flows. Companies in some select industries naturally have a high level of non-cash earnings and it is not a major concern. However, in the worst case scenario it can be an early sign of performance manipulation by management. Currently, the following risks have been identified for the company: Major Risk High level of non-cash earnings (23% accrual ratio). Minor Risks Profit margins are more than 30% lower than last year (0.4% net profit margin). Market cap is less than US$100m (₩110.0b market cap, or US$75.0m). Announcement • Mar 15

New minor risk - Profit margin trend The company's profit margins are lower than last year and have reduced by more than 30%. Net profit margin: 0.7% Last year net profit margin: 1.1% This is considered a minor risk. A large drop in profit margin could indicate the company does not have strong competitive advantages or it is yet to establish itself and its core business. Even if it is a well established business, this may make it a much riskier investment than one that has a combination of proven competitive advantages and a stable or growing profit margin. Currently, the following risks have been identified for the company: Major Risk Share price has been highly volatile over the past 3 months (14% average weekly change).

New minor risk - Market cap size The company's market capitalization is less than US$100m. Market cap: ₩138.3b (US$99.3m) This is considered a minor risk.
