The glaring criticism for MM’s theory is that the assumptions underlining the chosen payout policy being inconsequential are themselves arguably irrelevant. However the fact that the assumptions are unrealistic does not denigrate the utility of the theory in regards to identifying how payout policies affect shareholder wealth. It is because perfect capital markets free from taxes, transaction costs and information costs do not exist that MM’s theory can be utilised as a start point for the greater explanation as to what elements within the market affect payout policy. The theory can assist in the understanding of why companies take a particular approach to dividend policy and what could be the subsequent consequences for shareholder wealth (Cohen & Grace, 2009). For example back in June 2010 after the oil spill in the Gulf of Mexico BP announced a cut to its dividend for that year. As previously mentioned managers prefer to avoid this option due to the negative share price affects often associated with reductions. It would appear however that BP, facing political pressure and fearing further public image decline thought the issuing of profits in a time of disaster may cause shareholder wealth to take a major hit as a result of greater backlash (Denning, 2010). This decision however can be shown to be ill conceived and potentially counter-productive through utilisation of MM’s theory to illustrate the affects market imperfections have on share price reactions to dividend decisions.
A key reason why the decision to reduce dividends could negatively impact shareholders is due to the subsequent information costs from unintentionally signalling new information to investors regarding future performance. MM’s theory assumes there are no signalling effects present in the market. However because this is not possible the reverse confirms the related information costs are a primary reason to consider dividend policy. The reduction of dividends typically creates a negative share price reaction. This is because the manager is perceived to have internal information in relation to future cash flows and therefore a dividend reduction would suggest these cash flows would be in decline. The BP situation could align with this hypothesis, as shareholders recognise a reduction in payout may be the company bracing for the impact of the clean up costs and impending legal
