Coca-Cola, the world's largest beverage company, has not used a financial advisor on its biggest acquisition to date, the $4.1bn (€3bn) purchase of an energy drinks company.

Coca-Cola is buying New York-based Energy Brands, known as glacéau, and neither company used a financial advisor. The company makes Vitaminwater, among other brands, and its products are directed at "active lifestyle" beverage drinkers.
