We derive a simple formula for the cost of the ESO to the firm at the grant date under the assumption that the executive has a constant market-to-strike multiple. The market-to-strike multiple is defined as the ratio of the market price on exercise to the strike price of the ESO. The expected...

We obtain explicit expressions for the subjective, objective and market value of perpetual executive stock options (ESOs) under exogenous employment shocks driven by an independent Poisson process. Previously, we obtain the executive's optimal exercise policy from the subjective valuation that...

We present an algorithm that merges a certainty-equivalence framework with the least-squares Monte Carlo algorithm to obtain the executive stock option (ESO) value for a risk-averse and undiversified agent. We account for the difference between executive's value and firm cost of the ESO. We show...

A market-leveraged stock unit (MSU) is a form of employee compensation in which the number of shares received on the vesting date depends on the stock price at that time. MSUs have been proposed as a way of overcoming some of the drawbacks of stock options and restricted stock units. In this...

In this paper I develop a theoretical model in which an executive exercises her option package (ESO) in fractions to diversify into other assets. I find that fractional exercises affect ESO values considerably for companies with highly volatile stock returns compared to a model with assumed full...

This paper develops a new pricing model for American-style indexed executive stock options. We rely on a basic model framework and an indexation scheme first proposed by Johnson and Tian (2000a) in their analysis of European-style indexed options. Our derivation of the valuation formula...

This paper examines how forfeiture, vesting, and early exercise affect the value of employee stock options. The forfeiture and exogenous exercise of the options are modeled as two Poisson processes with constant intensity. Rational exercise by the employee due to the option's American feature is...

More than half of S&P 500 CEOs receive options annually, however extant valuation models have not accounted for portfolio considerations. We show the inability of executives to diversify means portfolio effects matter: exercise thresholds and shareholder costs are lower than for stand-alone...

This paper examines the use of stock options by Australian IPOs. Stock options in this setting exhibit heterogeneity of ‘in the moneyness' attributes. We can therefore identify incentive ‘out of the money' options and reward ‘at or in the money' options and study their usage. The setting...

We examine the ex-ante optimality of repricing of executive stock options while considering the tax effects of new accounting rules associated with traditional repricing. Although there has been a body of empirical literature on repricing, the optimality of repricing after considering the...
