The internal affairs doctrine ensures that such issues as voting rights of shareholders, distributions of
dividends and corporate
property, and the
fiduciary obligations of management are all determined in accordance with the law of the state in which the company is incorporated. On the other hand, the "external affairs" of a corporation, such as
labor and employment issues and
tax liability, are typically governed by the law of the state in which the corporation is doing business. Some issues and activities, such as
contracts,
mergers and acquisitions, and sales of
securities to third parties, may be governed both by the laws of the state of incorporation and by the laws of the state in which the transaction takes place, and in some cases, by
federal law as well (for example,
United States securities law and
antitrust law). ==Relation to federalism==
