This research provides an alternative framework for the analysis of employee stock option exercise patterns. It develops a binomial model where the exercise decision obeys to a policy that maximizes the expected utility to a representative employee exhibiting preferences as described by the...

This research provides an alternative framework for the valuation of standard employee stock options and for the analysis of exercise behavior patterns. It develops a binomial model where the exercise decision obeys to a policy that maximizes the expected utility to a representative employee...

This paper determines the cost of employee stock options (ESOs) to shareholders. I present a pricing method that seeks to replicate the empirics of exercise and cancellation as good as possible. In a first step, an intensity-based pricing model of El Karoui and Martellini is adapted to the needs...

This study contributes to the valuation of employee stock options (ESO) in two ways: First, a new pricing model is presented, admitting a major part of calculations to be solved in closed form. Designed with a focus on good replication of empirics, the model fits with publicly observable...

We present a valuation framework that captures the main characteristics of employee stock options (ESOs), which financial regulations now require to be expensed in firms' accounting statements. The value of these options is much less than Black-Scholes prices for corresponding market-traded...

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...

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...
