While KFC's infamous Double Down was a promotional coup for fast-food operator Restaurant Brands, the company's chief financial officer says it had a negative impact on profits.
The limited edition bun-less chicken burger prompted a storm of media coverage and more than 16,000 were sold in the first three hours after they hit the market in May.
But it was not KFC's most profitable menu item, and as thousands of Double Downs were consumed, higher-margin products went unordered.
"It did cannibalise some of our better-margin products," said Grant Ellis, Restaurant Brands' chief financial officer. The company's chief executive, Russell Creedy, said last year that the bun-less burger also ate into sales at the listed company's Pizza Hut stores.
In October the firm - which also operates Starbucks stores - reported a net profit of $8.6 million for the first six months of its financial year, a 38.4 per cent drop on the previous comparable period.
