Concept:Amalgamation is the complete combination of two or more firms into one new company, where all original firms lose their separate identities.
Explanation:When firms amalgamate, each existing company stops existing as an independent unit.
The firms bring their assets, liabilities, and operations together to form a brand new business.
This new company takes over all the rights and obligations of the merged firms.
The original companies are then dissolved and no longer operate separately.
This is different from a holding company, consortium, or cartel, where the firms retain some form of separate identity or independence.
Only an amalgamation involves the total loss of identity for all the merging firms.
