Section 372A of the Companies Act, 1956 outlines the conditions under which a company can make loans, acquire securities, or provide guarantees, stipulating that prior board approval or a special resolution is required depending on the amount involved. It permits certain relaxations, such as allowing guarantees exceeding the ceiling limit under specific conditions, and applies to specific types of companies while excluding financial and insurance firms. Non-compliance can result in penalties and the transactions being declared void and ineffective.
