Hvad er et inc. firma?

Betyder vist bare at man er registreret som firma:

"The process by which a company receives a state's permission to function as a corporation. After incorporation, the company will show that it is incorporated by adding the word "incorporated" into its name. "Inc." or other acceptable abbreviations may be used. "

Inc. = Incorporated (ved ikke om det er stavet ordenligt)- men det er lidt det samme som vore ApS firmaer herhjemme.
