Answer:
In order to significantly influence the decisions Killearn Company has to have 51% shareholding of Shaun company. This 51% shareholding significantly increases the voting rights and gives a controlling position.
Step-by-step explanation:
Holding majority shares of the company i.e 51% imparts voting rights to shareholders and increases their influence in making key decisions like appointment of CEO, appointment of auditors etc.
In the case mentioned Killearn is having 25% holding which results in having a minority interest and not a controlling position.
However in scenarios where 2/3rd majority is required minority shareholders like Killearn can be consulted.
Minority shareholders can be consulted and have a position in the board of directors.
