Hyder Reconsiders Spin-off of Power Business

LCG, July 18, 2000--Hyder, the Welsh water and energy utility being pursued by the Japanese investment bank Nomura Securities and WPD, a U.S. venture between PPL Inc. and The Southern Co., said in a statement yesterday that it was reconsidering a separate sale of its electricity business.

The company said that earlier this year it had considered selling the electricity business and transferring its water business to an alternative ownership structure but had backed off because of loan conventions which would have required the company to pay off much of its 1.67 billion ($2.5 billion U.S.) debt at significant premiums.

The company said lenders have since indicated that they would be more flexible so the possibility of the breakup of the company was being reconsidered.

"The board has decided to re-examine this option with a view to offering shareholders greater value than either of the current offers and has appointed Merrill Lynch to work with its other advisors in developing this possibility," the company said in its statement.

Nomura had offered 402 million ($602 million) for the company earlier this year. WPD has since offered 464 million ($695 million) and has received approval from the European Commission.
