Liquidation Valuation is an analysis to determine the value of a company after all of their assets have been sold off and they have paid off their liabilities.
A Liquidation valuation analysis would typically be performed in a bankruptcy scenario to determine whether or not equity shareholders would receive any capital after the company's debts have been paid off.
This analysis would help a struggling business to know if it would be better to sell off all its assets separately or to sell the entire company as a whole.
