How Might Companies Value ESOs

There has been a steady growth in the use of employee equity compensation plans, and in the use of executive stock options (ESOs) in particular, along with a rise in shareholder and public perceptions that the values of compensation plans are not always fully disclosed. The IFSA of Australia recently called for separate reporting in financial statements of numbers and values of ESOs. Companies, when negotiating employment contracts, frequently agree to compensate an executive if a share option plan is subsequently not approved by shareholders. These facts suggest that reporting the value of an ESO plan is a useful and important exercise. We outline a model for the valuation of ESOs typically issued by Australian listed companies and illustrate the application of the model with a case study.
