If a company has capital investment opportunities that will have a positive NPV,
it should invest in them because they will add to the value of the company and
its shares.
The capital to invest in these projects should be obtained internally (from
earnings) if possible.
The amount of dividends paid by a company should be the residual amount of
earnings remaining after all these available capital projects have been funded by
retained earnings.
In this way, the company will maximise its total value and the market price of its
shares.
A practical problem with residual theory is that annual dividends will fluctuate,
depending on the availability of worthwhile capital projects. Shareholders will
therefore be unable to predict what their dividends will be.
4.5 Modigliani and Miller’s theory of the irrelevance of dividend policy
Modigliani and Miller (MM) developed a theory to suggest that dividend policy is
irrelevant, and the level of dividends paid out by a company does not matter. The
total market value of a company will be the same regardless of whether the
dividend payout ratio is 0%, 100% or any ratio in between.
Their theory was based on certain assumptions. One of these was that taxation (and
the differing tax position of shareholders and companies) can be ignored. Their
theory assumes a tax-free situation.
MM argued that the value of a company’s shares depends on the rate of return it
can earn from its business. ‘Earning power’ matters, but dividends do not. They
argued that if a company has opportunities for investing in capital projects with a
positive NPV, they can either:
use retained earnings to finance the investment, or
pay out earnings and dividends and obtain the equity that it needs for capital
investment from the stock market.
For example if a company has earnings of $100 million and investment
opportunities costing $100 million that have a positive NPV, it does not matter
whether it pays no dividend and invests all its earnings on the capital projects, or
whether it pays dividends of $100 million and raises new equity capital of $100
million for the capital project investments.
If the company pays out dividends and raises new equity capital, the existing shares
will fall in value by the amount of the dividend payments. However this loss of
value will be replaced by the new equity raised in the market, so the total value of
the company’s equity will be unaffected.
Loss in value of existing shares = Amount of dividends paid
Total value of equity before the dividend payment and equity issue = Total
value of equity after the dividend payment and equity issue
