In Corporate finance M&A section, if a firm engages in split off, i.e. split of assets to form a new company, then shareholders are allowed to exchange their existing shares in the parent company for the new company's shares, who decides who gets those shares? *e.g. in the case when there is high demand for the new company's shares, and in the case when there is very little demand for the new company's shares. Therefore who actually gets the shares of the new company after a split off? Who decides?
thank you!!!!!
