Control is most commonly measured by voting power—holding more than 50% of the voting equity of the company. In some cases, when there is no majority stockholder, other circumstances can lead to one owner having effective control.

When a buyer does not exist, the noncontrolling owner effectively has no exit option. Continuing to hold the investment is a liquidity option to the extent that the business pays dividends.
