Beyond NPV – Simulation, Options and Trees • Enterprise Risk Management • Sensitivity Analysis • Scenario Analysis • Monte Carlo Simulation • Real Options • Decision Trees • Market Values • Economic Rents and Competitive Advantage • Warren Buffet on Growth and Profitability
Credit Derivatives • Total return swap • One party pays interest and capital gains/losses • Other party pays floating (or fixed) interest rate • Credit default swap • Fastest growing derivative • Insurers and reinsurers heavily involved • One party pays a periodic fee • Other party pays any losses incurred in default or from credit downgrade • Similar to insurance, but risk could be highly correlated
Operational Risk Causes of operational risk • Internal processes • People • Systems Examples • Product recall • Customer satisfaction • Information technology • Labor dispute • Management fraud
Strategic Risk Examples • Competition • Regulation • Technological innovation • Political impediments
Traditional Approach to Risk Management • Risks are handled separately (silos) • Corporate risk manager handles hazard risks • CFO or investment department handles financial risks • Managers handle operating risk • CEO (or C-suite) handles strategic risk • Each area has its own approach • Terminology • Risk tolerance • Reports • No overall coordination or aggregation
Aggregate Risk Management • Strategic Risk • Regulation • Reputation • Competition • Hazard Risk • Hurricanes • Lawsuits • Injuries • Financial Risk • Credit Risk • Market Risk • Interest Rates • Operational Risk • Internal Fraud • Recalls ERM Approach
What is Driving ERM? • Board of Directors concern about what can go wrong • Regulators are evaluating all aspects of risk • Rating agencies are considering a firm’s ERM policies • Need for one person or group to be responsible for risk oversight • Chief Risk Officer • Technological advances • Computing power • Analytical techniques • ERM is moving from risk control to risk optimization
Sensitivity Analysis • Calculate the NPV of a project based on expected values • Estimate optimistic and pessimistic values for each key variable • Recalculate NPV by changing each key variable in turn • Determine which variables could impact the investment decision • Try to improve estimates for those variables
Problems with Sensitivity Analysis • Meaning of “optimistic” and “pessimistic” • How likely is each to occur • Are terms used consistently • Variables are not independent
Scenario Analysis • Considers interrelations among variables • Defines a set of potential developments • Calculates the NPV for each situation • Problems • Limited number of scenarios • No indication of likelihood of any scenario
Monte Carlo Simulation • Determine the key variables that impact operations • Develop a financial model to simulate cash flows • Run multiple iterations • Calculate the NPV of each iteration • Evaluate the outcomes in aggregate • Decide if the investment is acceptable given the potential NPV
Advantages and Disadvantages of Simulation • Advantages • Shows the results of many possible developments • Indicates how likely any particular outcome is • Considers the interrelations between variables • Disadvantages • Time consuming and costly to develop useful model • Models need to be continually updated • Over reliance on the model con lead to costly errors
Real Options • Projects are usually not single decision situations • Options include decisions to: • Expand • Abandon • Defer • Real options covered later (Chapter 22)
Decision Trees • Shows each decision sequentially • Provides for random elements for business conditions that will be revealed in future • Work through trees from back to front

Nuggets from Chapter 11 • Use market values wherever possible • Financial models will include errors • Consider economic rents and competitive advantage • Can Google protect its competitive advantage? • Consider how competitors will react • Warren Buffet on the automobile and airlines industries • Look for long term economic advantage
