Introduction

The Grand Historian records: At the end of the campaign, the emperor must judge his generals. But by what measure? The general who conquered the most territory may have spent the most treasure. The general who spent the least may have avoided all risk. The general who earned the highest return on his war chest may have done so by refusing to invest in future campaigns. Performance measurement is the art of choosing the right measure — and compensation design is the art of ensuring that what you measure is what you actually want.

Horngren (Chapter 23) concludes the cost accounting journey with performance measurement and compensation — the systems that close the loop between strategy, execution, and reward. These systems determine behavior more powerfully than any mission statement or strategic plan.

Return on Investment (ROI)

ROI = Operating Income / Total Assets (or Invested Capital)

The DuPont Decomposition

ROI can be decomposed into two components that reveal different aspects of performance:

ROI = Income Margin × Asset Turnover

= (Operating Income / Revenue) × (Revenue / Total Assets)

A luxury goods company may have high margin but low turnover; a discount retailer may have low margin but high turnover. Both can achieve acceptable ROI through different strategies.

Limitations of ROI

• Underinvestment problem: A division manager may reject positive-NPV projects that would lower the division’s ROI (because the project’s return is above the company’s cost of capital but below the division’s current ROI). This destroys shareholder value.
• Short-term focus: Managers may cut R&D, training, and maintenance to boost short-term ROI at the expense of long-term health.
• Asset base distortion: Older divisions with fully depreciated assets show artificially high ROI, making comparisons unfair.

Residual Income (RI)

RI = Operating Income − (Required Rate of Return × Total Assets)

RI eliminates the underinvestment problem. A project is accepted if it generates positive residual income — if its return exceeds the required rate. The division manager is incentivized to accept any project that earns above the hurdle rate, regardless of its effect on the division’s average ROI.

Economic Value Added (EVA)

EVA is a refinement of RI developed by Stern Stewart & Co.:

EVA = After-tax Operating Income − (WACC × Total Capital Employed)

EVA makes several adjustments to accounting income to better approximate economic profit:

• Capitalize and amortize R&D expenditures rather than expensing them immediately.
• Add back goodwill amortization.
• Adjust for operating leases (treat as debt).
• Use the weighted-average cost of capital (WACC) as the charge rate.

太史公曰：EVA asks the most fundamental question in business: After paying the cost of all capital employed — both debt and equity — did we create or destroy value? A company that reports accounting profit but earns less than its cost of capital is slowly destroying shareholder wealth, even as the income statement proclaims success.

Designing Compensation Systems

Principles of Effective Compensation

• Alignment: Compensation metrics should align with strategic objectives. What you measure and reward is what you get.
• Controllability: Managers should be compensated based on outcomes they can influence, not on uncontrollable factors.
• Balance: Use a mix of financial and non-financial metrics (recall the Balanced Scorecard). Pure financial targets invite gaming.
• Time horizon: Include both short-term (annual bonus) and long-term (stock options, deferred compensation) elements to discourage myopic decision-making.
• Simplicity: Overly complex compensation formulas confuse rather than motivate. If the manager cannot explain how their bonus is calculated, the system has failed.

Common Compensation Structures

The Agency Problem and Moral Hazard

The fundamental challenge: managers (agents) may not act in the best interests of shareholders (principals). Compensation systems are the primary mechanism for aligning interests:

• Moral hazard: After being hired, managers may shirk or take excessive risks because they bear less downside than shareholders.
• Information asymmetry: Managers know more about operations than shareholders — they can manipulate metrics.
• Clawback provisions: Require return of bonuses if later evidence reveals manipulation or restatement.

Key Takeaways

• ROI = Income Margin × Asset Turnover (DuPont). Simple and comparable but creates underinvestment incentives.
• Residual Income eliminates the underinvestment problem by charging for capital employed.
• EVA refines RI with accounting adjustments to approximate true economic profit.
• Compensation systems must align with strategy, balance short- and long-term metrics, and minimize gaming incentives.
• The agency problem requires compensation design that aligns manager and shareholder interests — including clawback provisions for accountability.

What’s Next

This concludes Module 9 and the advanced Accounting track. You have journeyed from the fundamentals of cost behavior through budgeting, variance analysis, decision-making, pricing, and strategic performance measurement. The Grand Historian salutes your perseverance — go forth and let no variance go unexplained, no cost go untraced, and no decision go unexamined.
