U.S. CORPORATE FINANCE - NEW ZEALAND DLR FRNS Floating-rate notes denominated in a foreign currency, a relatively new wrinkle on Wall Street, will probably be issued infrequently because the so-called "window of opportunity" opens and closes quickly, traders say. "In just two days we had as many issues. As a result, the market became glutted," said one trader. He said the window depends more on supply than on foreign exchange or interest rate risk, at least for the moment. "Obviously, currency risk is important. But there is a limited number of investors right now for the paper," he said. On Thursday, Bear, Stearns and Co sole-managed a 100 mln New Zealand dlr offering of three-year floating-rate notes issued by Ford Motor Credit Co, a unit of Ford Motor Co <F>. The initial rate for the notes will be set on April 15, and quarterly after that, at 200 basis points below the 90-day New Zealand bank bill rate. They are non-callable for life. This followed by a week another Bear Stearns-led offering of the same amount of New Zealand dollar notes for Dow Chemical Co <DOW>. The initial rate was also to be initially set on April 15, and quarterly after that, at 340 basis points below the same 90-day New Zealand rate. Because the Dow Chemical notes carried an interest rate floor of 17 pct, the issue saw strong investor demand, underwriters said. But the Ford Credit notes and Friday's offering of 130 mln New Zealand dlrs of floating-rate notes due 1990 issued by General Electric Co's <GE> General Electric Credit Corp via Prudential-Bache Securities Inc, did not have such a floor. "Obviously, the two firms did not want to issue floaters and face the risk of New Zealand rates falling sharply," an underwriter away from the syndicates said. He and others noted that the New Zealand 90-day rate was 27 pct late last week. An underwriter familiar with the Dow Chemical deal pointed out that because of the interest rate and currency swaps Dow did, the issuer felt comfortable setting a rate floor. Domestic offerings of foreign currency denominated date first surfaced in Fall 1985. By using currency and rate swaps, companies can sell debt that pays a high interest rate in a foreign currency like Australian or New Zealand dollars. But the issuers actually realize savings on borrowing costs. "I would say that every company which issued foreign currency debt saved some basis points when compared to same-maturity plain vanilla U.S. issues," an analyst said. Investors, mainly institutions, were attracted to the early issues because of the high interest rates. They were willing to absorb foreign currency risk until mid-1986, when sharp slides posted by the Australian and New Zealand dollars brought such issuance to a quick halt. It was not until late last year, after the currencies stabilized, that companies again started issuing debt denominated in Australian and New Zealand dollars. But many investors have still shied away from the debt, remembering the mid-1986 downturn of the Australian and New Zealand dollars, analysts noted. To attract some of those investors back to the fold, underwriters like Bear Stearns decided to structure the foreign currency issues as floating rate debt, sources said. This occurred against a backdrop of uncertainty over the course of U.S. interest rates for the intermediate term, and predictions by a number of economists that Treasury yields would rise in the second half of the year, the sources noted. A Bear Stearns officer said more than half of the Ford Credit notes were sold by late Friday afternoon, the second day of offering. "That is quicker than some recent fixed-rate New Zealand dollar note issues," he said. However, underwriters away from the Bear Stearns syndicate said the issue may have sold even faster if Prudential-Bache did not offer the General Electric Credit notes on Friday. They pointed out that the Ford notes were rated A-1 by Moody's Investors and AA-minus by Standard and Poor's, while the General Electric notes, which had the same interest rate terms and were also non-callable to maturity, carried top-flight AAA ratings by both agencies. "We have sold 20 to 25 pct of the GE notes. For first-day sales on a Friday afternoon, I'm happy with the results," an officer on Prudential-Bache's syndicate desk said. Investors pay the U.S. dollar equivalent of the foreign currency-denominated notes, underwriters said. Investment bankers said the next floating-rate issue of New Zealand or Australian dollar-denominated debt is probably a few weeks away. "I would like to underwrite a deal a day. But with the Dow, Ford and GE offerings, the marketplace has had enough for the time being," the Prudential-Bache officer admitted. Meanwhile, IDD Information Services said the 30-day corporate visible supply fell to 3.29 billion dlrs last week from 3.98 billion dlrs in the previous week.
