What is a book-closure/record date?

Book closure and record date help a company determine exactly the shareholders of a company as on a given date.

Book closure refers to the closing of register of the names or investors in the records of a company. Companies announce book closure dates from time to time. The benefits of dividends, bonus issues, rights issue accruing to investors whose name appears on the company's records as on a given date, is known as the record date.

An investor might purchase a share-cum-dividend, cum rights or cum bonus and may therefore expect to receive these benefits as the new shareholder. In order to receive this, the share has to be transferred in the investor's name, or he would stand deprived of the benefits. The buyer of such a share will be a loser. It is important for a buyer of a share to ensure that shares purchased at cum benefits prices are transferred before book-closure. It must be ensured that the price paid for the shares is ex-benefit and not cum benefit.
