Maximization of the wealth of equity shareholders

Are there other aims, besides the aim or maximum shareholders wealth, expressing the shareholders viewpoint?
Several alternatives have been suggested for this, such as maximization of profit, maximization of earnings per share, maximization of equity which is defined as equity earnings/ net worth.
Maximization of profit is not as all-encompassing a goal as maximization of shareholder wealth. It undergoes from several limitations:

The aim of maximization of earnings per share and maximization of return on equity do not suffer from the first limitation mentioned. They, anyhow, suffer from the other limitations and thus are not suitable.
In view of the shortcomings of the alternatives, maximization of the wealth of equity shareholders comes into view to be the most suitable aim for financial decision making. Although the strict validity of this aim rests on certain stiff assumptions about capital markets, it can be logically defined as a guide for financial decision making under fairly plausible assumptions.
