Which of the following are American brands: Gevalia, Saab, Jacobs Suchard, Dunkin' Donuts, Toblerone, Bird's Custard, Vegemite?

This may surprise you: With one exception, they are all American-owned, and the foreigner in the group is none other than Dunkin' Donuts, a wholly owned subsidiary of the British company Allied Domecq PLC.

Clearly, consumers abroad whose aim is to boycott U.S. goods and services have their work cut out for them.

Even with companies that have become American icons -- think Coca-Cola, McDonald's, Microsoft -- the matter of who loses when the brands are shunned by consumers overseas isn't that simple.

Certainly, Coca-Cola has a lot to lose if boycotts catch on outside the United States. By far, most of the company's sales -- 68 percent of a total $19.3 billion last year -- were derived from drinks bought outside North America, leaving the majority of its sales particularly vulnerable to protests overseas.

But when Coke, Fanta and the company's dozens of other brands are sold abroad, they are, by and large, also bottled there, by local employees working for local subsidiaries operating in the local economy. So while Coke's world headquarters in Atlanta feels the pinch when Europeans boycott, so do some Europeans.

By contrast, only 26 percent of Microsoft's $28.4 billion in sales last year were made overseas, which presumably would limit the potential damage of a foreign boycott.

Here's a look at some of the other most valuable American brands and the percentage of their parent companies' total sales derived overseas:

General Electric: 34 percent

IBM: 60 percent

Intel: 68 percent

McDonald's: 54 percent
