Billionaire investor Warren Buffett is said to be helping to finance Burger King Worldwide Inc’s planned merger with Tim Hortons Inc as talks continue between the two groups.
Burger King would create the world’s third-largest fast-food chain by merging with Canada’s biggest seller of coffee and doughnuts.
The deal renews debate over American companies shifting their headquarters internationally in search of lower corporate tax bills. The Canadian corporate tax rate is typically 26.5%, compared with 40% in the US.
The trend drew criticism last month from President Barack Obama, and his aides vowed that the administration would take action to curtail the practice.
