British Gas Trading, a subsidiary of Centrica, has entered a GBP40 million (USD62.5 million) multi-season winter weather hedge that uses a daily collar structure, rather than the more traditional heating degree-day index, to determine season-end payouts. Gearoid Lane, head of electricity supplies at Centrica, said the collar structure allowed coverage to be more concentrated in particular high-risk months, such as January. "We were able to sculpt the coverage much more to our risk," he added. One weather official said collar structures are gaining in popularity because of that flexibility.
