For corporate citizenship in diversity, which factor determines the principal place of business (nerve center)?

• A. The state where the company is incorporated.
• B. The location of the company's legal headquarters only.
• C. The principal place of business, or nerve center, of the corporation.
• D. The location of its largest revenue-generating unit.

Answer: (C)

For corporate citizenship in diversity, the principal place of business is determined by the nerve center: the location where the corporation’s high-level officers direct, control, and coordinate the company’s activities. This is the place where the major decisions are made and where the company’s central management operates, typically the corporate headquarters.

This concept, known as the nerve center, is the key factor used to determine the principal place of business for citizenship purposes. The state of incorporation matters as the other component of corporate citizenship, but it does not define the nerve center itself. The location of the largest revenue-generating unit is not relevant to establishing the nerve center, and simply identifying a legal headquarters location doesn’t always capture where decision-making actually occurs.

So the factor that determines the principal place of business (nerve center) is the nerve center—the central location of the corporation’s management and control.
