Till the year 2000, when DVR shares were introduced in India for the first time, ‘one share, one vote’ had been the base-rock principle of the financial world. But what is DVR share? DVR stands for shares that have differential voting rights. This means that shareholders holding DVR shares have more or less voting rights than shareholders holding equity shares. But under Indian law, companies are not allowed to issue equity shares with superior voting rights, so only DVR shares with limited voting rights are issued in the stock market.
DVR shares differ from common shares in two major ways:
1) They carry fewer voting rights than ordinary shares. Hence, the shareholder may not have the right to vote, but retain other rights like bonus shares, rights share issues etc.
2) DVR shares are usually offered at a discount which means the investment amount can be much lower than investing in ordinary shares.
3) Shareholders holding DVR shares receive a higher dividend than common shares to compensate for the sacrifice of their vote
To grow and expand in today’s world, companies need capital. Often, the founders and key stakeholders have to reach out to potential shareholders who would be willing to invest in the company. But it also means reducing power and taking away some control. DVR shares help companies protect their interests and enable them to raise additional capital needed to keep the business running.
Therefore, issuing DVR shares is a great solution to get investors who are looking for investment but do not want to participate in the working of the business. The company can also control how many voting rights they want to be given. DVR shares also provide protection against hostile takeovers. Without voting rights, shareholders cannot command a majority and challenge to take control of the company.
1) Strategic Investment – DVR shares provide you with an opportunity to reap the benefits of a highly successful business venture without having to worry about the day-to-day affairs of the company.
2) Discounted rate – DVR shares are listed in the stock market at a lower price which means your investment budget is also smaller
3) Better Dividend – DVR shares give higher returns than normal shares. Maximum 10-20 per cent. And since these shares are quoted at discounted rates, the dividend yields are more profitable.
