PITTSBURGH, PA-- - Koppers Inc., a wholly-owned subsidiary of Koppers Holdings Inc. (NYSE: KOP), announced today that it has substantially completed a legal reorganization of its foreign subsidiaries that will allow the company to repatriate cash from its foreign subsidiaries at a lower overall tax cost and is expected to lower the company's effective tax rate on annual pretax income.

Some of the benefits of the reorganization include the potential future cash repatriation from foreign subsidiaries of approximately $250 million, future cash tax savings of approximately $8 million annually, and an estimated effective tax rate reduction of 6-7% that should result in an increase to the company's annual earnings per share of approximately $0.30.

The legal reorganization will result in one-time cash tax payments of approximately $16 million that are expected to be paid in the first half of 2015. In addition, the company's lenders have agreed to exclude the $16 million tax payment from the company's fixed charge covenant calculation.

Koppers also announced that it has modified the construction schedule for the previously disclosed North American CMC restructuring project to more effectively manage its cash position. The discretionary project includes the construction of a naphthalene plant at the Stickney, Illinois facility at an estimated cost of $40-45 million that is expected to result in annual cost savings of approximately $10-15 million. The construction of the naphthalene plant in Stickney, Illinois is required in order to cease production at the company's Follansbee, West Virginia facility which is currently the only facility in North America that produces naphthalene. The required environmental permits have been approved, and site preparation and engineering work are expected to continue. The majority of the estimated cost is now more likely to be incurred in 2016.

Leroy Ball, president and CEO of Koppers, said, "I am pleased that we have completed our legal entity reorganization project and look forward to the significant cash and EPS benefits that Koppers should receive as a result." Mr. Ball continued, "Regarding the delay of construction for the naphthalene plant at our Stickney, Illinois facility, we believe this is a prudent cash management strategy as we navigate through the impact of lower oil prices on our business. However, we continue to believe strongly in the benefits this project will bring to Koppers longer-term. Our revised schedule provides flexibility to accelerate construction if market conditions improve, but if market conditions do not improve then it is our intention to maintain construction at this more appropriate pace."
