A corporation needs sustainable income in order to cover all of its expenses in the long run.
What is Sustainable income?
Sustainable income represents the after-tax gain or loss on the impact of operations on a discontinued segment of business for a period.
Therefore, in the case of a discontinued operation, there is no sustainable income arising in the future as the segment of business is already discontinued and income, if any, is going to come only for the period of the discontinued operation. Income or expense from discontinued operations is a line of item in the income statement of a company below income from continuing operations and before the net income.
