All material prices for semi-finished products and materials are based on market research, publicly available information and audited cost models. It is our claim that this information as best as possible are correct and are usable. Our semi-finished steel prices are based on the mapping of cost structures in the steel industry. Our costing models for the production based on knowledge of the process and take account of raw material costs, exchange rates, energy costs, quipment costs, transport costs and personnel costs. In addition, we use econometric models, which we have built to reflect macroeconomic factors such as profits and overheads for pricing due to market dynamics. However, real steel prices include a number of other factors do not account for our models. These include trade rules as import safeguards, anti-dumping measures, tariffs and other governmental interference in the normal trade patterns. About a third of steel production in a country can flow into the export. Changes in local market conditions of a country can thus have an impact on the pricing in other parts of the world. Minimum order charges, additional processing costs and processing costs in the field of coatings, quality certificates and special tests are not included in our prices. Accordingly, our prices can only reflect a lower price limit generally.
