Brehm Chapter 1:
Enterprise Risk Management
ERM is the process of systematically and comprehensively identifying critical risks, quantifying their impacts and implementing integrated strategies to maximize enterprise value.

Brehm Chapter 1: Types of Insurance Company Risk Factors
Insurance Hazard Risk - risk assumed by the insurer for a premium
Financial Risk - risk in the insurer’s asset portfolio due to volatility in interest rates, foreign exchange rates, equity prices, credit quality, and liquidity
Operational Risk - risk associated with the execution of the company’s business
Strategic Risks - the risks of strategic choices made by the company
Brehm Chapter 1:
Enterprise Risk Management Process
The ERM process can be described as a sequence of steps:
Diagnose - firm conducts a risk assessment to determine material risks that exceed a company-defined threshold
Analyze - risks that exceed a company threshold are modelled as best as possible:
Implement - implement various activities to manage the risks
Monitor - monitor the actual outcomes vs. expected and update plans
Brehm Chapter 1: Goal Enterprise Risk Modeling
Goal is to understand and quantify the relationships among risks from assets, liabilities and underwriting.
Enterprise Risk Models combine several risk sub-models to produce an overall risk profile of the business.
Brehm Chapter 1: Enterprise Risk Modeling
These models help with the insurer with important management functions and strategic decisions such as:

Elements Needed for Effective ERM Model
A good enterprise risk model has the following characteristics:
Brehm Chapter 1:
What are the essential elements of the enterprise risk model?
Brehm Chapter 1: Essential Elements of Enterprise Risk Model
Underwriting Risk
1. Loss Frequency and Severity Distributions
2. Pricing Risk
3. Parameter Risk
4. Catastrophe Modeling Uncertainty
Brehm Chapter 1: Essential Elements of Enterprise Risk Model
Underwriting Risk - Parameter Risk
Estimation Risk - misestimation of model parameters due to imperfect data
Projection Risk - changes over time and the uncertainty in the projections of these changes. (e.g driving increases since fuel is cheaper, criminals attack security vehicles because banks are more secure)
Event Risk - events outside the company’s control that impact frequency/severity trends (e.g. class action, asbestos, new cause of loss, etc.)
Systematic Risk - risk that cannot be diversified away and affects many policies (such as inflation)

Brehm Chapter 2: Corporate Decision Making using ER Model
What is the three-step evolutionary process?
*Trying to determine cashflows to use in IRR or NPV calculation to see how risks impact the value of the firm. Based on this info, company can make decisions.

For a public firm, why might a certainty equivalent approach with a corporate risk preference be undesirable?
Brehm Chapter 2: Corporate Decision Making using ER Model
There are 5 major elements in internal risk modeling. Brehm focuses on the 5th one.
What are the sub-components of the 5th component?
Brehm Chapter 2: Corporate Decision Making using ER Model
Decision making with IRM: We desire a mechanism with the following steps:
Step 1: Determine an aggregate loss distribution with many sources of risk (e.g. lines of business)
Step 2: Quantify or assess the impact of possible aggregate loss outcomes on the company
Step 3: Assign a cost to each amount of impact
Step 4: Attribute the cost back to the risk sources
