Feb 09, 2005. /Lesprom Network/. Mercer International Inc. (MERCS.O), which owns pulp and paper mills in Germany, on Wednesday priced a public offering of 9.4 million shares at $8.50 a share to raise gross proceeds of about $80 million. Mercer also priced a separate public offering of $310 million of senior notes. The notes will pay interest at a rate of 9.25 percent a year and mature in 2013. The proceeds of both offerings, and cash on hand, will be used to pay the cash portion of the purchase of Canada's Celgar pulp mill and its working capital, transaction costs, and to repay the bank debt of the company's Rosenthal pulp mill.
