The quantity and quality of coke produced by the Group may be lower than customers expect

Production capacities of the coking batteries may be affected by a number of factors remaining outside of the Group's control. These forecasts inevitably contain some level of uncertainty and to this extent they rely on economic and technical assumptions made, which in the end may prove to be imprecise. As a result, estimates concerning coke production are regularly checked on the basis of new information; as a result, one should expect that they may change. If the actual coke production capacity by the Group is lower than the current estimates then this may adversely affect the Group's outlook and value and its operations, performance and financial standing.

Due to the economic slowdown in 2012, the Group used about 75% of the production capacity of its coking plants.
