Section 186 of the Companies Act 2013 governs loans, investments, guarantees and security provided by companies. It places limits on such activities and requires prior approval if certain thresholds are exceeded. Companies must disclose full particulars of such transactions in their financial statements and maintain a register containing details of loans, guarantees, security and acquisitions. Certain exceptions apply for banks, insurance companies, housing finance companies and those principally engaged in financing or infrastructure activities. Contravention of this section may result in fines for the company and imprisonment for officers in default.
