An Australian and a U.S. energy company last week entered into what is believed to be the first weather derivative basket option based on four cities in Australia. The payout on the November to March contract, which covers the Australian summer, is capped at USD4 million and was brokered by United Weather in Jersey City, N.J. Philippe Chauvancy, director of United Weather Europe, said the basket option is based on Sydney, Melbourne, Brisbane and Adelaide. He declined to name the counterparties.
