The bird flue epidemic is expected to hit your town and it is estimated that 600 people will die. Which of the following two drugs, C or D, will people recommend to combat the epidemic, given the following information? • If Drug C is used : 400 will die. • If Drug D is used: 1/3 chance that nobody will die, and 2/3 chance that 600 will die. • It seems a greater percentage of the respondents vote for Drug D.
Key messages • Our attitudes towards risk are highly perplexing. • The essence of good risk management is making the right choices when it comes to dealing with different risks . • Risk management should not be equated with risk hedging. • The most successful companies rise to the top by embracing risks they can exploit better than their competitors. • Some risks are “black swans”. • They come when we least expect them but their effects can be catastrophic. • An integrated approach to risk management can be highly rewarding.
How Enterprise Risk Management adds value • Enterprise Risk management creates value at both a “macro” or company-wide level and a “micro” or business-unit level. • At the macro level, ERM enables senior managers to quantify and manage the risk-return tradeoff that faces the entire firm . • At the micro level, ERM becomes a way of life for managers and employees at all levels of the company.
What determines the value of a firm? • The value of a firm can generally be considered a function of four key inputs • Cash flow from assets in place or investments already made • Expected growth rate in cash flows during a period of high growth excess returns • Time before stable growth sets in and excess returns are eliminated • Discount rate which reflects both the risk of the investment and the financing mix used by the firm
What can a firm do to increase its value? • Generate more cash flows from existing assets • Grow faster or more efficiently during the high growth phase • Prolong the high growth phase • Lower the cost of capital • What is the role of risk management in adding value to firm?
How hedging can help? • Managers often under invest because of risk aversion. • By providing hedging tools, we can remove the disincentive that prevents them from investing. • By hedging and smoothening earnings, firms can extend their high growth/excess returns period . • Hedging firm specific risks can align the interest of stockholders and managers, leading to higher firm value. • The pay off from risk hedging is greater for firms with weak corporate governance structures. • The payoff is also greater in case of managers with long tenure.
How taking risk helps • The way the firm strategically manages its risk exposure, such as by making the right R&D investments, will clearly help in extending the growth phase. • Taking risk has higher pay offs in businesses that are volatile but yield high returns on investment. • We must look for the positive black swans!
Benefits of Risk management : A Summary Researchers have identified various value-increasing benefits of risk management that can generally be classified as reduction in expected costs related to the following: • Tax payments, • Financial distress, • Underinvestment, • Asymmetric information, • Undiversifiable stakeholders
Risk Management Failures • Failure to use appropriate risk metrics. • Wrong measurement of known risks. • Failure to take known risks into account. • Failure in communicating risks to top management. • Failure in monitoring and managing risks.
Strategy, Finance, Operations : Need for integration • Risk management as a discipline has evolved unevenly across different functional areas. • In strategy, the focus has been on competitive advantage and barriers to entry. • In finance, the preoccupation has been with hedging and discount rates. Little attention has been paid to the upside. • People in charge of operations may not have the big picture. • Risk management at most organizations is splintered. • There is little communication between those who assess risk and those who make decisions based on those risk assessments.
Three ways to manage risk Fundamentally, there are three ways to manage risk. Which are these ways?
Different approaches to managing risk Integrated Risk Management for the Firm: A Senior Manager’s Guide, Working paper by Lisa K. Meulbroek
Risks in P&C Insurance Ref : ERM- An Insurance perspective and overview, Calandro, Fusler, Sansone
Integrated risk management • “Integration” refers to the combination of these three risk management techniques, and to the aggregation of all the risks faced by the firm. • Integrated risk management is by its nature “strategic”, rather than “tactical”. • Because the three ways to manage risk are functionally equivalent in their effect on risk, their use connects seemingly-unrelated managerial decisions. • For instance, capital structure decisions cannot be decided in isolation from the firm’s other risk management decisions. • Can we think of some examples?
Modifying operations to gain competitive advantage • Companies are in business to take strategic and business risks. • By reducing non-core exposures, ERM effectively enables companies to take more strategic business risks. • Consider the following : • Pharma R&D • Human capital management in software company • Cricket pitch during rainy season • Environmental management • Oil company
When to hold the risk? • Companies should be guided by the principle of comparative advantage in risk-bearing. • A company that has no special ability to forecast market variables has no comparative advantage in bearing the risk associated with those variables. • But the same company may have a comparative advantage in bearing information-intensive, firm-specific business risks. • That is because it knows more about these risks than anybody else.
Risk transfer using targeted financial instruments • When should firms use targeted financial instruments? • Some risks cannot be managed effectively through the operations of the firm. • Either because no feasible operational approach exists. • Or an operational solution is simply too expensive to implement or it is too disruptive of the firm’s strategic goals. • Targeted financial instruments are especially suited for firms with large exposures to commodity prices, currencies, interest rates, or the overall stock market.
Risk adjustment via the capital structure • By decreasing the amount of debt in the capital structure, managers can reduce the shareholder’s total risk exposure. • Lower debt means that the firm has fewer fixed expenses. • This translates into greater flexibility in responding to any type of volatility that affects firm value . • Lower debt also reduces the chance that the firm becomes financially distressed.
Equity: An all purpose cushion • Equity provides an all-purpose risk cushion against loss. • There are some risks that a firm can both anticipate and measure relatively precisely. • Such riskscan be shed through targeted risk management. • Equity provides ideal protection against • risks that cannot be readily anticipated or measured, • or for which no specific targeted financial instrument exists . • The larger the amount of risk that cannot be accurately measured or shed, the larger the firm’s equity cushion should be.

Liquidity, model and market risks Liquidity, market and model risks are interrelated. Breakdown of markets leads to liquidity problems. When markets are not in place, models become necessary. Models pose various risks.
Credit and market risks are inter related. • Consider bonds. • Change in credit rating can lead to change in bond price • Consider swaps. • Change in value can lead to credit risk. • Financial disintermediation has led to more integration. Credit and Market risks
Market and operational risks are interrelated • When positions move, losses may have to be booked. • Trader’s psychology may lead to systems and processes being breached. • More risks may be taken than warranted. • Sound systems and processes can help. Market and operational Risks
The duality of risk • It is part of human nature to be attracted to risk. • At the same time, there is evidence that human beings try to avoid risk in both physical and financial pursuits. • Some individuals take more risk than others.
Behavioural finance and prospect theory • Decisions are affected by the way choices are framed. • Individuals may be risk seeking in some situations and risk averse in others. • Individuals feel more pain from losses than from equivalent gains.
Propositions about risk aversion (1/2) • Individuals are generally risk averse and more so when the stakes are large than when they are small. • There are big differences in risk aversion across the population and noticeable differences across sub groups. • Individuals are far more affected by losses than by equivalent gains. • The choices that people make when presented with risky choices or gambles depend on how the choice is presented. • Individuals tend to be much more willing to take risk with what they consider found money than with money they have earned. Ref : Strategic Risk Taking, AswathDamodaran
Propositions about risk aversion (2/2) • There are two scenarios where risk aversion seems to decrease and is even replaced by risk seeking. • One is when individuals are offered the chance of making an extremely large sum with a small probability of success. • The other is when individuals who have lost money are presented with choices that give them a chance to get their money back. • When faced with risky choices, individuals often make mistakes in assessing the probabilities of outcomes, over estimating the likelihood of success. • The problem gets worse as the choices become more complex.
Risk Management vs. Risk hedging • Risk management is aimed at generating higher and more sustainable excess returns. • The benefits of risk management will be greatest in businesses with high volatility and strong barriers to entry. • The greater the range of firm specific risks, the greater the potential for risk management. • Risk management will create more value if new entrants can be kept out of business.
Managing the upside • A simple vision of successful risk taking is to expand our exposure to upside risk while reducing the potential for downside risk. • The excess returns on new investments and the length of the high growth period will be directly affected by decisions on how much risk to take in new investments . • There is a positive pay off to risk taking but not if it is reckless. • Firms that are selective about the risks they take can exploit these risks to their advantage. • Firms that take risks without sufficiently preparing for their consequences can be hurt badly.
