Extra dividend can be referred to by several synonyms, such as bonus dividend, special dividend, additional payout, and surplus payment. These terms all imply an additional financial incentive or reward given to shareholders, above and beyond the regular dividend payouts. Bonus dividend is often used to express gratitude to shareholders for their support and loyalty, while special dividend typically denotes a one-time payment that is not part of the regular dividend policy. Additional payout and surplus payment both imply that there is excess cash available to be distributed to shareholders. Regardless of the terminology used, extra dividend payments can benefit investors by increasing their return on investment.
