These charges have been added back to the revised guidance

These charges have been added back to the revised guidance.The company's fourth quarter results have been negatively impacted byvolatility in demand and pricing for certain company end-market products,combined with raw material costs that have negatively impacted margins.The volatility in product pricing relates primarily to products that areimpacted by petroleum prices, including carbon black feedstocks andphthalic anhydride. Fourth quarter earnings have also been negativelyimpacted by incremental charges that total approximately $17 million.These charges include approximately $12 million for inventory write-downsto net realizable value and incremental LIFO charges. Additionalincremental charges include approximately $4 million of impairment chargesfor a non-core business in Europe and approximately $1 million ofseverance charges related to cost reduction initiatives. In addition tothe impacts to operating income, the company will change assumptionsrelating to repatriation of foreign earnings that will negatively impactincome tax expense in the fourth quarter resulting in a higher annualeffective tax rate of approximately 46. The cumulative impact of thisadjustment will be reflected in fourth quarter tax expense.Walter W. Turner, President and CEO of Koppers, said, "We certainlycontinue to believe in the long-term end-market fundamentals for our coreproducts and are confident that we are well-positioned to manage throughthis current economic downturn. However, we have seen our globalaluminum, steel, rubber and plasticizer end markets come under increasingdistress in recent months, resulting in substantially lower volumes andprices for some of our products.

We expect that the current volatilitywill continue in 2009 but that these markets will eventually return tomore normalized levels. In the interim, we have implemented variousinitiatives across the company to reduce costs, optimize operationalefficiencies and further improve on our current strong balance sheet. Wewill continue to monitor our operations to further optimize bothprofitability and cash flows as market conditions evolve due to theeconomic downturn.
