Last night there was a huge party at the New York Stock Exchange honoring the top 25 multinational corporations (where 40% of a company's workforce is stationed outside its headquarters).

The event was put on by the Great Place to Work Institute, which determined the list by surveying 2.5 million employees from more than 5,500 companies worldwide.

Employees were asked about workplace culture, and how much faith they have in their company.

Guess who's No. 1?

Great Place to Work determined rankings based on the average score from surveys sent to employees. Countries must be mentioned on lists from at least five countries to be considered a best multinational company.
