An IFRS 2 and FASB 123 (R) Compatible Model for the Valuation of Employee Stock Options

In this paper, we show how employee stock options can be valued under the new reporting standards IFRS 2 and FASB 123 (revised) for share-based payments. Both standards require companies to expense employee stock options at fair value. We propose a new valuation model, referred to as Enhanced American model, that complies with the new standards and produces fair values often lower than those generated by traditional models such as the Black–Scholes model or the adjusted Black–Scholes model. We also provide a sensitivity analysis of model input parameters and analyze the impact of the parameters on the fair value of the option. The valuation of employee stock options requires an accurate estimation of the exercise behavior. We show how the exercise behavior can be modeled in a binomial tree and demonstrate the relevance of the input parameters in the calibration of the model to an estimated expected life of the option.

The Subjective Valuation of Indexed Stock Options and Their Incentive Effects

We analyze the potential role of indexed stock options in future pay‐for‐performance executive compensation contracts. We present a unified framework for index‐linked stock options, discuss their incentive effects, argue that indexation schemes based on the capital‐asset pricing model (CAPM) are the most suitable for executive compensation, and derive a subjective pricing model for the class of CAPM‐based indexed stock options. Contrary to earlier work, executives would not be motivated to take on investment projects with high idiosyncratic risk once their lack of wealth diversification and degree of risk aversion are factored into the analysis.     

Incentive Efficiency of Stock versus Options

This paper examines the relative incentive costs of using stockversus options in management incentive contracts that use market priceas the performance measure. We establish that if the manager'seffort has little or no effect on a firm's operating risk, thenthe cost of incentive risk is less using stock rather than options.However, this result is reversed if the manager's effort has asignificant impact on the firm's operating risk.     

A Model of Equity Based Compensation with Tax

In this paper, we develop a two‐stage continuous time model of employee stock option (ESO) valuation under different tax regimes. We show that tax rules can have significant effects on ESO exercise behavior. In addition, we find that incentive stock options (ISO) are the optimal form of compensation for all levels of employees in the UK. In the US, restricted stock plans are preferred, and tax breaks offered by incentive schemes are only beneficial to employees with high liquid wealth (or small option holdings relative to wealth) or low risk aversion. We also analyze 83b elections for restricted stock plans in the US and find that making an election is a sub‐optimal decision for both the employee and the firm.     

EVA IN THE E&P INDUSTRY: THE CASE OF NUEVO ENERGY

This article presents a case study illustrating some aspects of the new business model discussed in the roundtable above. Continuing a major theme in the roundtable, the authors begin by arguing that the long‐run failure of the E&P industry to create shareholder wealth stems to a large degree from weak or distorted incentives held out to the top executives and managers of most large, publicly traded companies. This article traces the incentive problem to the lack of an effective wealth creation metric to guide the financial management process. Although the industry employs a variety of accounting‐based performance measures, none is a reliable measure of wealth creation. In place of traditional financial metrics such as earnings, annual cash flow, and return on capital, this article recommends a performance evaluation and incentive compensation system that is tied to the use of a “reserve‐adjusted” EVA measure—one that exhibits a strong statistical correlation with changes in shareholder wealth in the E&P business. The greater explanatory power of this new measure reflects the reality that changes in the value of reserves in the ground can greatly outweigh changes in annual earnings or cash flows. As the focal point of a compensation plan, EVA has advantages over stock options in that it can be calculated at various levels in the organization, even at the level of a single well, whereas stock prices only exist for the company as a whole. For this reason, an EVA incentive system permits a clearer “line of sight” between pay packages and the performance of the part of the business for which managers are directly accountable. Perhaps even more important, EVA can be calculated (using an “internal hedging” mechanism) in a way that removes the impact of changes in oil prices on the incentive outcome. And, as demonstrated in the case study of Nuevo Energy, such internal hedging allows companies to give their employees a much greater share of wealth created with far less cost than by simply granting stock or stock options.     

Executive stock option vesting conditions,corporate governance and CEO attributes: evidence from Australia

We investigate the association between executive stock option (ESO) vesting conditions, corporate governance and CEO attributes. Using observations from the 250 largest Australian firms, we find that stronger corporate governance is positively associated with the length of the vesting period and the use of performance hurdles. We also find that when CEOs approach retirement, firms are more likely to grant longer time‐vesting options but are less likely to impose performance hurdles. Further, more powerful CEOs appear to influence the granting of ESOs with less restrictive vesting conditions. Our findings suggest that both corporate governance and CEO attributes significantly shape the design of ESOs.     

Dynamic financial contracting with persistent private information

We study a dynamic agency model where the agent privately observes the firm's cash flows that are subject to persistent shocks. We characterize the policy dynamics and implement the optimal contract by financial securities. Because bad performance distorts investors' beliefs downward, the agent has less incentive to misrepresent information. The agent's compensation is less than what he can divert and is convex in performance. As private information becomes more persistent, (i) the agent is compensated more by stock options; (ii) firm credit limits vary more with history, dropping after bad performance; (iii) the firm is financially constrained for longer time.     

Motivating Innovation

Motivating innovation is important in many incentive problems. This paper shows that the optimal innovation‐motivating incentive scheme exhibits substantial tolerance (or even reward) for early failure and reward for long‐term success. Moreover, commitment to a long‐term compensation plan, job security, and timely feedback on performance are essential to motivate innovation. In the context of managerial compensation, the optimal innovation‐motivating incentive scheme can be implemented via a combination of stock options with long vesting periods, option repricing, golden parachutes, and managerial entrenchment.     

The impact of the market portfolio on the valuation,incentives and optimality of executive stock options

This paper examines the effect on valuation and incentives of allowing executives receiving options to trade on the market portfolio. We propose a continuous time utility maximization model to value stock and option compensation from the executive's perspective. The executive may invest non-option wealth in the market and riskless asset but not in the company stock itself, leaving them subject to firm-specific risk for incentive?purposes. Since the executive is risk averse, this unhedgeable firm risk leads them to place less value on the options than their cost to the company.

By distinguishing between these two types of risks, we are able to examine the effect of stock volatility, firm-specific risk and market risk on the value to the executive. In particular, options do not give incentive to increase total risk, but rather to increase the proportion of market relative to firm-specific risk, so executives prefer high beta companies. The paper also examines the relationship between risk and incentives, and finds firm-specific risk decreases incentives whilst market risk may decrease incentives depending on other parameters. The model supports the use of stock rather than options if the company can adjust cash pay when granting stock-based compensation.     

CEO Stock Options and Equity Risk Incentives

Abstract:   We test the hypothesis that the risk incentive effects of CEO stock option grants motivate managers to take on more risk than they would otherwise. Using a sample of mergers we document that the ratio of post‐ to pre‐merger stock return variance is positively related to the risk incentive effect of CEO stock option compensation but this relationship is conditioned on firm size, with firm size having a moderating effect on the risk incentive effect of stock options. Using a broader time‐series cross‐sectional sample of firms we find a strong positive relationship between CEO risk incentive embedded in the stock options and subsequent equity return volatility. As in the case of the merger sample, this relationship is stronger for smaller firms.

Executive compensation and internal capital market efficiency

We document that chief executive officer (CEO) incentive compensation plays an important role in determining internal capital market (ICM) allocation efficiency. Our results suggest that CEO equity-based compensation can be effective in ameliorating inefficiencies in internal capital allocation decisions. We find that while stock grants play an important role in motivating CEOs to make more efficient internal capital allocation decisions, there is surprisingly no discernible influence of stock options. Our analysis supports the view that private benefits derived by managers are increasing in internal capital misallocation. We also document a strong positive link between CEO incentive compensation and excess value of diversified firms suggesting that the diversification discount can be ameliorated with CEO incentive compensation. The study contributes to the ICM literature and the literature on conglomerate diversification discount.     

Revisiting the incentive effects of executive stock options

We develop a multiperiod framework to evaluate the incentive effects of executive stock options (ESOs). For a given increase in the grant-date firm stock price (and a concurrent increase in return volatility), the increment of total value at the vesting date acts as a proxy for the incentive effects of ESOs. If the option is attached to the existing contract without adjusting cash compensation, we suggest that a firm should not always fix the strike price to the grant-date stock price; instead, the strike price should vary with the length of the vesting period. We also show that, compared with at-the-money options, restricted stock generates greater incentives to increase stock prices in some scenarios, especially when equity-based awards are vested early. If the vesting period is long, the firm could grant options instead of restricted stock to maximize incentives.     

Valuing employee stock options under SFAS 123R using the Black–Scholes–Merton and lattice model approaches

In 2004, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standard No. 123 (revised 2004), Share-Based Payments (SFAS 123R), requiring all entities to recognize as expense the fair value of stock options issued to employees for services provided. Because employee stock options cannot be traded publicly, their fair value must be estimated using a model, with the Black–Scholes–Merton (BSM) and lattice models being the most appropriate alternatives.This teaching note provides an overview of employee stock options, followed by a discussion of the BSM and lattice valuation models, including their application and limitations. A project which has been used in financial accounting courses is also presented. The conceptual discussion coupled with illustrated examples will help students enhance their understanding of fair value estimation of and accounting for employee stock options under the recently adopted SFAS 123R.     

DIFFERENTIAL RISK‐TAKING IMPLICATIONS OF PERFORMANCE INCENTIVES FROM STOCK AND STOCK OPTION HOLDINGS

We study the risk‐taking implications of managerial pay‐for‐performance incentives (delta) arising from stock and stock options separately in the United States between 1992 and 2017. The current literature assumes that each unit of delta has an equal incentive effect on firm performance. Instead, we show that the risk‐reducing effect of performance incentives is more pronounced for executives whose delta comes mostly from stock holdings relative to option holdings. Accordingly, we propose a new measure that takes into account the magnitude of delta from option holdings relative to delta from stock holdings (source ratio). Our results show that risk taking increases as this ratio increases.     

Financial crisis and bank executive incentive compensation

We study the executive compensation structure in 14 of the largest U.S. financial institutions during 2000–2008. We focus on the CEO's purchases and sales of their bank's stock, their salary and bonus, and the capital losses these CEOs incur due to the dramatic share price declines in 2008. We consider three measures of risk-taking by these banks. Our results are mostly consistent with and supportive of the findings of Bebchuk, Cohen and Spamann (2010), that is, managerial incentives matter — incentives generated by executive compensation programs are correlated with excessive risk-taking by banks. Also, our results are generally not supportive of the conclusions of Fahlenbrach and Stulz (2011) that the poor performance of banks during the crisis was the result of unforeseen risk. We recommend that bank executive incentive compensation should only consist of restricted stock and restricted stock options — restricted in the sense that the executive cannot sell the shares or exercise the options for two to four years after their last day in office. The above incentive compensation proposal logically leads to a complementary proposal regarding a bank's capital structure, namely, banks should be financed with considerably more equity than they are being financed currently.     

TRANSFERABLE STOCK OPTIONS (TSOS) AND THE COMING REVOLUTION IN EQUITY-BASED PAY

The dominant form of equity pay in the U.S. will change dramatically when accounting rules are changed (most likely in 2005) to require companies to charge the cost of their stock option plans on their income statements. Many companies are already switching from stock options to other forms of equity pay, especially restricted stock. The most notable switcher was Microsoft, the world's largest user of stock option pay. In July 2003, partnering with J.P. Morgan, Microsoft created a onetime transferable stock option (TSO) program that allowed holders of underwater Microsoft options to sell their options to J.P. Morgan in return for restricted shares.
But the most important consequence of this transaction may not be a widespread shift by corporate America to restricted shares, but rather the creation of a more costeffective kind of stock option. By clearing the potentially messy hurdles involving taxes, accounting, SEC rules, and "transaction mechanics," Microsoft has opened the door for TSOs to be considered as an ongoing equitypay instrument, perhaps replacing standard stock options (which are not transferable). TSOs share the key advantages of restricted stock in terms of providing robust retention and ownership incentives and higher valuecost efficiency, while maintaining the key "leverage" advantage of options. In so doing, they create significant upside (and downside) while largely avoiding the "pay for pulse" problem of restricted stock. They also introduce the discipline of competitive pricing by third-party bidders. The bid prices of investment banks create nearly all of the information required for accurate estimates of option cost, which should foster greater board accountability and improved corporate governance.     

Employee Stock Options, Equity Valuation, and the Valuation of Option Grants Using a Warrant-Pricing Model

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 nature of ESO and shareholder values. The empirical results show that our stock price estimate exhibits lower prediction errors and higher explanatory powers for actual share price than does the traditional stock price estimate. We use our valuation approach to assess the implications of dilution on the fair‐value estimates of ESO grants. We find that the fair value is overstated by 6% if we ignore the dilutive feature of ESOs. Furthermore, this bias is larger for firms that are heavy users of ESOs, small, and R&D intensive, and for firms that have a broad‐based ESO compensation plan.     

Too much of a good incentive? The case of executive stock options

Using a utility-maximization framework, I show that the incentive to increase stock price does not always increase as more options are granted. Keeping the total cost of his compensation fixed, granting more options creates greater incentives to increase stock price only if option wealth does not exceed a certain fraction of total wealth. Beyond this critical level, granting more options actually reduces incentive effects and becomes counterproductive. In addition, stock options also create incentive to reduce (increase) idiosyncratic (systematic) risk. These incentive effects are sensitive to the choice of exercise price.     

An empirical examination of the costs and benefits of executive stock options: Evidence from Japan

In May 1997, the Japanese Commercial Code was amended to allow firms to begin granting stock options as compensation to top management and employees. Nearly 350 firms adopted option-based compensation plans between 1997 and 2001. These options typically have five-year lives and are out-of-the-money by about 5% at the grant date. Firms exhibit abnormal stock returns of about 2% around the announcements of plan adoptions. We find improvements in operating performance and observe that dividend policy and volatility remain unchanged post-adoption. Our evidence suggests that well-designed incentive compensation plans are consistent with the creation of shareholder value.
