Stanley Forman Reed,
Ford Motor Company v. Beauchamp…
“ We reject petitioner's contention that constitutionality of state taxation turns on so narrow an issue as whether local assets rather than local gross receipts are used in a taxing formula.In a unitary enterprise, property outside the state, when correlated in use with property within the state, necessarily affects the worth of the privilege within the state. Financial power inherent in the possession of assets may be applied, with flexibility, at whatever point within or without the state the managers of the business may determine. ”
