I. Overview
Risk management is the identification, assessment, and prioritization of risks followed by coordinated and economical application of resources to minimize, monitor, and control the probability and/or impact of unfortunate events. 1
Risks can come from uncertainty in financial markets, project failures, legal liabilities, credit risk, accidents, natural causes and disasters as well as deliberate attacks from an adversary..

I. Overview
What is Risk Management?
Risk management is the identification of events that could result in unwanted negative consequences or economic losses and then taking steps to mitigate or manage those events.
Ultimately risk management is planning for the unlikely event that could cause harm.

using historical data
Primarily qualitative at this point, use tools such as “heat maps”
etc.

I. Overview (continued)
More Examples:More Examples:• GPA Risk Management
− When you take a couple difficult classes in a semester, do you look for some easier classes to offset?
− If so then you are actively managing your GPA risk
− You might be able to manage all hard classes but why take that risk?
• Career Risk Management
− Did you join SAS just to make or friends or were you looking to build your resume and network with employers?
• Event Risk Management
− If you needed to be in Minneapolis tomorrow at 10 AM for an important interview, what time would you leave?

II. Financial Crisis (continued)
• After September 11, 2001 and during the subsequent recession the US adopted a loose monetary policy (keep America rolling, go out and shop)
Credit became cheap, underwriting standards were loosened, consumers treated their houses as ATM’s and borrowed against the increase values, thus increasing consumer spending
Consumer spending is roughly 70% of US GDP
• Complex investments / products were developed and sold to investors that were based on housing and consumer credit
Securitization led to wide dispersion of credit risk, the use of credit default swaps and derivatives exploded, adding further dispersion of risk
These products were highly complex

II. Financial Crisis (continued)
• Memories were short: things were too good for too long
• Ultimately there was too much leverage in the financial system / economy as credit risk was drastically undervalued

II. Financial Crisis (continued)
• Risk Managers Relied too Heavily on Historical Data
US housing prices never decreased in the past, therefore it was assumed they would not in the future, this was a critical assumption that did not come true
• Hubris: Risk Managers Relied too Heavily on Quantitative Models
• Risk Managers Assumed Individual Risks were not Correlated
Correlation goes to 1 in a crisis

II. Financial Crisis (continued)
• Models Became Too Complex
Advancements in computing power resulted in incredibly complex models, too complex for most people to fully understand
• In short: What Was Deemed Statistically Remote Actually Happened and Nobody was Prepared for it

II. Financial Crisis (continued)
• The good news: we now have a large tail event to include in our models (the current crisis)
• Ensure proper rewards and punishments, not just rewards – current bonus structure shares only upside
• Counter balance complexity with simplicity
“Derivatives are financial weapons of mass destruction” Warren Buffet
• Consider model assumptions and output in the context of what makes sense, including qualitative considerations
• Push for counter-cyclical loss reserving

V. Summary and Recap
• Risk management is about preparing for unlikely events
• Reliance on historical data and quantitative models, coupled with hubris and bad assumptions, greatly contributed to the current financial crisis
• Common sense and qualitative considerations should always be layered on top of any model
• Overly complex models can make the situation worse
• Everyone is a risk manager at some level
• There is plenty of good reading out there on risk management, both case studies and technical analysis and theories
