We derive a pricing model for employee stock options (ESO) that expands on Ingersoll (2006) by including default risk and that additionally considers the effects of employee over-confidence. We find that illiquidity reduces subjective value and alters incentive effects and value sensitivities....

According to the Revised FAS Statement No. 123 issued on December 16, 2004, (FAS123R) the accounting treatment of employee stock options (ESOs) for U.S. companies will be radically different in the near future. Although, FAS 123R does not specify a particular valuation technique as preferable,...

We gather data from 77 current mid-level managers and 111 future entry-level managers, to investigate how they value stock options and restricted stock. We refer to our current and future manager groups collectively as quot;managers.quot; We supplement our manager data with a dozen field...

This paper examines the issues and controversies over the question of whether executive stock options should be expensed and, if so, how option values should be determined. It identifies and clarifies the key questions and surveys and synthesizes the academic and trade literature. Illustrations...

The reload provision in an employee stock option is an option enhancement that allows the employee to pay the strike upon exercising the stock option using his owned stocks and to receive new reload stock options. The usual Black-Scholes risk neutral valuation approach cannot be adopted as the...

We investigate the use of a warrant-pricing approach to incorporate employee stock options (ESOs) into equity valuation and to account for the dilutive effect of ESOs in the valuation of option grants for financial reporting purposes. Our valuation approach accounts for the jointly determined...

The Financial Accounting Standards Board has recently endorsed a proposal that will require firms to calculate and recognize as a cost of compensation the value of employee stock options at the time those options are granted. Conventional models such as the Black and Scholes or binomial models,...

We investigate the use of a warrant-pricing approach to incorporate employee stock options (ESOs) into equity valuation and to account for the dilutive effect of ESOs in the valuation of option grants for financial reporting purposes. Our valuation approach accounts for the jointly determined...

One of the arguments often used against expensing employee stock options is that calculating their fair value at the time they are granted is very difficult. This article presents an approach to calculating the value of employee stock options that is practical, easy to implement, and...

We study the problem of hedging early exercise (American) options with respect to exponential utility within a general incomplete market model. This leads us to construct a duality formula involving relative entropy minimization and optimal stopping. We further consider claims with multiple...
