What are the best run megacorporations?

CSM email newsletter carries this summarization of a Fortune article:

They're big, successful, and admired: top companies in US Blue-chip businesses, those with great bottom lines, are almost by definition well run. That's why they dominate Fortune magazine's annual list of most admired companies. General Electric tops the 2007 list, and the remainder of the Top 10 hardly need an introduction either. To conduct the survey for Fortune, pollsters for the Hay Group tallied the opinions of more than 3,000 executives, directors, and securities analysts on eight criteria, among them people management, quality of products, investment value, and social responsibility. The 10 most-admired companies operating in the US, and the countries where each maintains its headquarters:

1.) General Electric US
2.) Toyota Japan
3.) Procter & Gamble US
4.) Johnson & Johnson US
5.) Apple US
6.) Berkshire Hathaway US
7.) FedEx US
8.) Microsoft US
9.) BMW Germany
10. PepsiCo US
