Weatherford International Inc. (NYSE: WFT), Houston, privately placed $910 million of 20-year zero-coupon senior convertible debt. The oilfield service and supply company will use the approximately $501 million of net proceeds to pay existing short-term debt and for general corporate purposes. The company said the private placement will reduce its average cost of capital significantly. The debt, which was issued at an original issue discount of $551.26 per debenture, has a yield to maturity of 3% per annum. It is convertible into common shares of the Houston oilfield supply company at a rate of 9.9970 shares per $1,000 face amount of debt. That effectively represents a price of $55.1425 per share, or a 37% premium on the stock's June 26 closing price. Under the debt's terms, the conversion rate will not be adjusted for the accrued original issued discount. But the debt's conversion price will, in effect, increase with the accretion of the debt's discount. Weatherford said that this accretion will result in an effective conversion price of $64.25 on the issue's fifth anniversary, or approximately a 60% premium to the stock's June 26 closing price. Conoco Inc. (NYSE: COCb), Houston, launched an EU500-million commercial paper program. Deutsche Bank will arrange the program, which also will feature the issuance of Belgian treasury notes. The program is designed to complement Conoco's current $2-billion U.S. commercial paper program and will be used to provide an additional funding source for the company, which will be the sole issuing vehicle. The program allows Conoco to have a global commercial paper program and to expand its presence in the global capital markets, said Miguel W. Espinosa, the company's treasurer. The program will be used to reduce any U.S. commercial paper and is not expected to increase Conoco's current debt. In addition to Deutsche Bank, Goldman Sachs International and NatWest Global Financial Markets will be dealers of the Euro commercial paper. ING Barings / BBL will act as dealer for the Belgian treasury notes. Belco Oil & Gas Corp.
