Background

� “Economic Capital” usually refers to two things

� Economic Capital calculation

� Calculation of amount of “Required” Capital

Standard Accounting

� Standard Accounting tends to focus on the Income Statement

� Matching Revenues and Expenses

� May allow smoothing due to long-term nature of policies

� Balance Sheet is usually a result of Income assumptions

� For US Stat, Income for most Bonds is based on solely Coupons

� As a result, Bonds are held at Book Value

Standard Accounting

� Sometimes, this creates a difference between Accounting and Market Value

� Can happen on Assets

� More common on the Liability side

� When the difference is large enough, companies find a way around it

� Finite Reinsurance

� Term Insurance

Standard Accounting Risk

� With Standard Accounting, Risk usually occurs when the assumptions are violated

� Consider 2008 and US Stat

Page 9: Economic Capital: Key Modeling Considerations · 2014-11-11 · Key Modeling Considerations Daniel Finn. ... Resulted in some companies taking huge write-downs Some, like the Hartford,

Standard Accounting Risk

� Under US Stat accounting, most Bonds are carried at Book Value

� Exceptions for High Yield and downgraded bonds

� During 2008, Corporate spreads gapped out to unprecedented levels

� Some bonds got downgraded

� Majority just dropped in value

� Not a problem, though, for US Stat fillers

Standard Accounting Risk

� Then, a “funny” thing happened: the auditors got involved

� Under US GAAP, many of these bonds lost enough value to trigger an Other Than Temporary Investment (OTTI) write down

� Auditors stepped in and said: if you write it down for GAAP, we’re going to make you write it down for Stat, as well

� Resulted in some companies taking huge write-downs

� Some, like the Hartford, even needed to raise additional capital

Economic Capital

� Since Economic Capital focuses on solvency, it flips the accounting approach on its head

� Focus is on Balance Sheet

� Want something which is universal

� Life and P&C

� Across Multiple Economies

� Comparable across Companies

� Not easily manipulated

11

Page 12: Economic Capital: Key Modeling Considerations · 2014-11-11 · Key Modeling Considerations Daniel Finn. ... Resulted in some companies taking huge write-downs Some, like the Hartford,

Economic Capital

� For universal, need to strip away accounting issues

� Mark Assets and Liabilities to Market

� Reflect all obligations (e.g. Taxes)

� Risk then arises from Asset and Liabilities moving differently

Economic Capital

� There are a number of issues with this definition

� Biggest is valuing Liabilities

� Long term obligations

� No market to “trade” them on

� Can lead to differences between companies

� Different discount rates

� Magnitude of Risk Margin

Required Economic Capital

� Calculating Economic Capital usually just the first step

� Typically Followed by calculating “Required” Capital

� “Requirement” is based on why the Company holds Capital

� Who are the Stakeholders? Regulators? Rating Agencies?

� How much Capital do they require us to hold?

14

Page 15: Economic Capital: Key Modeling Considerations · 2014-11-11 · Key Modeling Considerations Daniel Finn. ... Resulted in some companies taking huge write-downs Some, like the Hartford,

Required Economic Capital

� Consider a Typical example

� Company needs their “A” rating to write business

� To be “A” rated, Rating Agency wants chance of default to be remote (say 1 in 500 over the next year)

� In this case, Company would

� Simulate a wide range of possible results

� Determine how much capital they lose in the 99.8% case.

� That amount is the “Required” Capital

� Key component of this approach is a robust Economic Scenario Generator (ESG)

� So, what makes a good ESG?

� Clearly, it has to model all of the Company’s Major Economic Risks

� Interest Rate

� Spread Changes

� Equity

� Inflation

� Consider Interest Rate risks

Managing Interest Rate Risk

� Most Companies can handle first two

� Shift can be managed by Duration

� Slope can be managed by adding key Rate Duration

� Twist is the one that can cause problems

� Assets tend to be Negatively Convex

� Liabilities tend to be Positively Convex

� Can create huge mismatches in Twist Scenarios

Common ESG Pitfall

� Don’t assume that missing capabilities aren’t a problem

� “It’s OK that my ESG doesn’t produce low rates, that’s not a risk for my company…”

� Let’s go back to the definition of Economic Capital

� Market value of assets

� - Discounted value of liabilities

� - Taxes

� Let’s go back to the definition of Economic Capital

� Market value of assets

� - Discounted value of liabilities

� - Taxes

� So, it is possible for the Economic Capital to increase with rising rates

� That’s why it’s so important to focus on the entire picture

Correlation

� Since we are focusing on total risk, another key factor is correlation

� One bad outcome is a problem

� Everything going wrong at once is a catastrophe

� Several ways to incorporate this is a model

� Correlation matrices

� Copulas

� Dependency structures

27

Correlation

� Most common approach is correlation matrices

� Easy to implement

� Fairly well understood by non-modelers

� There are some key concerns

� Become unwieldy for large variable sets

� Control over tail relationships

Correlation

� Modelers are moving towards Dependency Structures

� Results of one model feed into other downstream models

� e.g. Simulated interest Rates impacting Equity Returns

� Results in much more robust relationships

� Direct control over tail correlations

� More robust correlation dynamics

Model Complexity

� One final consideration is how complex the models need to be

� Answer really depends on the company

� Some lines have relatively little economic exposure

� Most P&C lines

� Whole Life Insurance

� Will allow a less robust economic modeling platform

� Others, have much more complex needs

Model Complexity

� Consider a Variable Annuity writer

� Lots of optionality built into the product

� Minimum guarantees

� Policyholder put options

� Typically backed with riskier and more dynamic assets

� Equities

� Volatility managed funds

� Foreign investments

� Typically include very active risk management

� Includes use of options to hedge Greeks

36

Page 37: Economic Capital: Key Modeling Considerations · 2014-11-11 · Key Modeling Considerations Daniel Finn. ... Resulted in some companies taking huge write-downs Some, like the Hartford,

Model Complexity

� Need a very robust model to adequately measure the risk

� Wide range of risky assets

� Linked options

� Variable management actions

� Without that, much more likely to miss the next big event

� Just think back to 2008

37

Page 38: Economic Capital: Key Modeling Considerations · 2014-11-11 · Key Modeling Considerations Daniel Finn. ... Resulted in some companies taking huge write-downs Some, like the Hartford,

Model Complexity

� Of course, 2008 saw huge drops in most Asset Classes

� Only partially offset by company’s hedging programs

� First problem: drops in underlying value brought more guarantees into play

� Increased Greeks

� Required purchase of lots of additional options

� Second problem: huge spike in option pricing volatilities

� Led to dramatic increase in cost of additional protection

38

Page 39: Economic Capital: Key Modeling Considerations · 2014-11-11 · Key Modeling Considerations Daniel Finn. ... Resulted in some companies taking huge write-downs Some, like the Hartford,

Key Benefits

� Key question for many companies:

� What do I get out of all of this?

� Better understanding of risk

� What could get us in trouble

� What can we do about it

� Improved ability to evaluate Risk/Reward tradeoffs

� What happens if we invest more aggressively?

� What if we bought less reinsurance?
