In the world of finance, there exists a term known as "additional sum". This term refers to an amount of money that is equivalent to the sum assured and is paid out when a claim is made. It is important to understand this concept as it directly impacts the payout received by the claimant. Essentially, the additional sum acts as a safety net, ensuring that the claimant receives the full amount they are entitled to. This reinforces the importance of carefully considering the sum assured when making financial decisions.
