2. Background of the Price Revision

The business environment surrounding the Resonac Chloroprene business has become increasingly challenging due to rising raw material costs driven by the situation in the Middle East, exceeding the limits of what can be absorbed through internal cost reduction efforts.
While the Company will continue to pursue cost reduction efforts, we have concluded that a price revision is necessary to maintain and sustain this business.
