Cum div differs from ex div in that, the later

Ex-dividend (ex div) refers to a period after a company has declared a dividend, but before the dividend is paid out to shareholders. During this period, if someone buys shares of the company, they will not be entitled to receive the upcoming dividend payment. On the other hand, if someone sells shares of the company during the ex-dividend period, they will still receive the upcoming dividend payment. Cum dividend (cum div) refers to a period before the ex-dividend period, during which someone who buys shares of the company is entitled to receive the upcoming dividend payment. In other words, if you buy shares of the company during the cum dividend period, you will receive the upcoming dividend payment, as opposed to the ex-dividend period, during which you will not receive the upcoming dividend payment. Therefore, the answer is: "entitles the purchaser to receive a company's current dividend."
