Divestment
In finance and economics, divestment or divestiture is the reduction of some kind of asset for financial, ethical, or political objectives or sale of an existing business by a firm. A divestment is the opposite of an investment.
Motives
Firms may have several motives for divestitures:
a firm may divest (sell) businesses that are not part of its core operations so that it can focus on what it does best. For example, Eastman Kodak, Ford Motor Company, Future Group and many other firms have sold various businesses that were not closely related to their core businesses.
to obtain funds. Divestitures generate funds for the firm because it is selling one of its businesses in exchange for cash. For example, CSX Corporation made divestitures to focus on its core railroad business and also to obtain funds so that it could pay off some of its existing debt.
a firm's "break-up" value is sometimes believed to be greater than the value of the firm as a whole. In other words, the sum of a firm's individual asset liquidation values exceeds the market value of the firm's combined assets. This encourages firms to sell off what would be worth more when liquidated than when retained.
