Mid-Atlantic Mutual Advantage Convention August 5, 2014 Economic Capital ModelingA Key Part of the ERM Process Ronald T. Kuehn, FCAS, MAAA, CERA, CPCU, ARM, FCA Consulting Actuary, Huggins Actuarial Services, Inc.
Definition of Economic Capital • Economic Capital is defined as • Sufficient surplus to cover adverse outcomes or to meet a business objective • With a given level of risk tolerance • Over a specified period of time
Definition of an Economic Capital Models (ECM) • One primary tool to assess risk in an insurance organization • Simulates the internal operations of the company relative to the external environment within which it is operating • Indicates future levels and volatility of profitability, and • Estimates appropriate amounts of capital to hold
ECM Can …. • Model • Company or Product Risk Profiles • Risk Tolerance, Constraints & Strategies • Insurance Pricing & Business strategies • Performance Measurements • Capital Adequacy & Budgeting • Incentive Compensation Investment & Risk-Adjusted Rates of Return • Merger & Acquisition Pricing Details • Capital Allocation Among Business Units
Key Risks Being Measured by a Comprehensive Economic Capital Model
Benefits of an Economic Capital Model Compliance Related ECM • Satisfy rating agency and regulatory criteria/inquiries • Aid in discussions with rating agencies and regulators • Capital adequacy measured against a company’s risk profile
Benefits of an Economic Capital Model Compliance Related • A.M. Best’s Supplemental Rating Questionnaire (no longer asks the ECM question as of year-end 2013) • Q 56: ECM – Risk Identification & Monitoring • Q 57: Frequency of Update to ECM and Measurement of Aggregate Risk • Q 58: Impact of Calendar Year Inflation on Reserves • Strong emphasis on Catastrophe Management (Updated as of January 14th, 2014) • Preparation of the ORSA summary report • Essential for Solvency II Compliance
Benefits of an Economic Capital Model Value Beyond Compliance More to gain from ECM than compliance • Improves risk awareness at all levels • Enables better risk/reward decisions making • Facilities linking strategy with planning • Empowers firm to improve value for stakeholders • Provides a competitive advantage including reduced cost of capital (University of Georgia Study 2013)
Insurance Companies & ECM A.M. Best 2010 ERM SRQ: • Overall 28% of respondents use ECM to quantify aggregate risk • Large (55%), • Medium (33%), and • Small (17%) • 8% use ECM for management compensation NAIC moving with European regulator EIOPA ? • Solvency II will allow companies capital relief by use of internal ECM rather than standard model
Insurance Companies & ECM • Savvy Investors, media, and the financial community speak language of risk modeling (VaR, TVaR, PML, etc.) • Demand more disclosure of metrics from ECMs. • Developing ECM is costly as it requires: • Acquiring actuarial and financial expertise • Collecting of significant volume data • Analyzing data to develop risk parameters • Licensing or building ECM software platform • Validating the model and organizing the management process for audit
Existing Capital Adequacy Measures • RBC (Risk-Based Capital) Ratio • Implemented by the NAIC in the 1990’s • Formulaic estimate of necessary surplus and comparison to reported surplus • Used to authorize regulatory intervention into financially-distressed • NAIC ORSA (Own Risk and Solvency Assessment) • Companies with at least $500 M WP • Group with at least $1B WP • Effective circa 2015
Insurance Companies & ECM • Rating Agency Measures: BCAR and others • Both formulaic and simulation-based • Used as significant input into assignment of financial strength ratings • Lack full transparency, as not all parameters are made public
Insurance Companies & ECM • Economic Capital Models (ECM’s) • Simulation based • Direct calculation of Economic Capital needed • Many other uses in addition to Economic Capital measure
Basic Inputs to an Economic Capital Model Balance Sheet Inputs: • Assets • Cash • Bonds • Common Stock • Other Asset Classes • Liabilities • Loss and Loss Adjust Reserves by Line / Subline • Payment patterns for Existing Reserves • Unearned Premium Reserve • Other Liabilities
Basic Inputs to an Economic Capital Model (Line of Business Inputs) • Direct Written Premium • Claim Payout Pattern for Newly Generated Loss • Underwriting Expenses • Earnings Pattern • Operational Risk – Lognormal Distribution
Basic Inputs to an Economic Capital Model (Cause of Loss) • Frequency and Severity Model – Frequency of Individual Claims with No Correlation • Claim Frequency Distribution - Examples • Poisson – often selected • Negative Binomial • Binomial
Basic Inputs to an Economic Capital Model (Cause of Loss) • Frequency and Severity Model – Severity of Individual Claims with No Correlation • Claim Severity Distribution - Examples • Lognormal – often selected • Exponential • Gamma • Generalized Pareto • Normal • Uniform • Weibull
Basic Inputs to an Economic Capital Model (Cause of Loss) • Aggregate Loss Model – Aggregate claims model can incorporate copulas (i.e., correlation between lines of business) • Aggregate Loss Distribution Examples • Lognormal • Generalized Pareto • Normal • Uniform • Weibull
Basic Inputs to an Economic Capital Model (Cause of Loss) • Selection of Copulas - adds correlation between lines of business • Normal Copula – linear correlation coefficient • Student’s T Copula – varies weight of coefficients in tail of distribution • HRT Copula – more weight in right tail of distribution • Partial Perfect Copula – mixes perfect correlation with uncorrelated
Basic Inputs to an Economic Capital Model (Reinsurance Inputs) • Reinsurance Contract Terms • Per Risk • Excess • Corridors • Ceded Premium • Ceded Reinsurance Attachment Point • Ceded Reinsurance Limit • Specific Catastrophe Reinsurance Terms • Reinsurance Catastrophe Modeling Results (i.e. AIR, EQECAT, RMS)
Basic Inputs to an Economic Capital Model (Economic Scenarios) • Leading edge economic models, providing full market risk and asset class coverage • Estimates inflationary changes, wage & CPI • Estimates of investment returns and default risk: • • US Treasury bonds• US, United Kingdom, and Euro stock markets• Emerging Markets stocks• Blue Chip Stocks• Corporate and Municipal bonds of varying quality • Master Limited Partnerships• Real Estate Investment Trusts (REITs)• Mortgage Backed Securities
Basic Outputs from an Economic Capital Model • Outputs include but are not limited to: • Over 180 customizable reports • Cumulative Probability Density Functions • Compare results from differing assumptions • Include effect of catastrophe losses • Calculates Value at Risk (VaR) & Tail Value at Risk (TVaR) • Pro Forma Financial Statements • Balance Sheet • Income Statement • Number of projected years is flexible
ECM - Key Risk Metrics Return on Equity = Net Income/Shareholder's Equity Value at Risk (VAR) – Maximum loss at no more than one minus the confidence level Tail Value at Risk (TVaR) – Expected loss in worst X percentage of distribution; also called CTE Risk Adjusted Performance – Measure risk adjusted returns on some established capital amount Return on Equity – Simple accounting performance metric
