The deal is the highest profile "inversion" scheme to reduce US federal taxes.

In the event BK has it its way, the combination would rank as the globe's No. 3 quick-service restaurant chain with sales of $22B.

3G would own a majority stake in the new entity. It maintains the top rationale for the hook-up is for Hortons to tap into BK's global marketing savvy to back its international growth.

Brunswick senior partner Steve Lipin and director Radina Russell provide media support to Miami-based BK.

Scott Bonikowsky, senior VP/corporate, PA & government affairs, is their counterpart at Hortons in Oakville (Ontario).
