Unequal rights of shareholders

Shareholders only have rights but no liabilities.

What rights do shareholders have?

• right to vote
• right to attend AGM and EGM
• right to receive the Annual Accounts
• right to receive dividends when declared

Issue - Do some shareholders have more rights than stated above? Do the above always hold true for every single shareholder?

The simple answer - Some shareholders do have more rights, whether rightfully or otherwise, than the others.

The following are real examples where my simple answer holds true:-

• The issue of consolidating the accounts of 2 companies which are publicly listed. The holding company requires a lot more than statutory info to prepare its consolidated accounts and satisfy its auditors. So we have possible situation of a majority shareholder being given access to non-publicly available info.
  

• How about the situation of a major shareholder getting sensitive info through its nominee directors in the subsidiary company? A nominee director is appointed by a major shareholder. Who do that director owe a duty and responsibility to? The major shareholder or to the company?
