 Early forecasts
 continued premium growth
 Combined ratio below 100%
 Record results through 2Q
 Despite reserve increases by several companies
 Worst hurricane season in 50 years
 Continued medical malpractice crisis
 Spitzer allegations turn the industry on its head

A “few” companies account
for much of the adverse development
 Calendar Year 2002: 30 companies accounted for 80%
of the one-year development
 Calendar Year 2003: 30 companies accounted for 90%
of the one-year development
 Not all the same companies as prior year
 The 30 companies (each year) held 20 – 25% of the
industry’s surplus

underestimates ultimate losses in a cyclical pattern

There are many process related drivers of
reserve development
 External environment
 Asbestos, pollution, construction defects
 Runaway juries
 Shock losses
 WTC, Enron, Mutual Funds, Vioxx(??)
 Methodologies
 Chain-ladder, expected loss estimates
 Data quality
 TPA handled claims, poor systems
 Knowledge of underlying exposure
©Towers Perrin
10
There are also decision-based questions that
can influence reserve adequacy
 When to move off of an expected loss estimate (peg)?
 Before IBNR is negative
 How bad can a given year really be?
 400% loss ratio is bad, 550% is worse
 When is noise really an underlying trend ?
 The “but for” rule
 What can we afford to take/release?
 Low end of talked down range
 Can you say bias
 Book the medium since reserves only go up

Like reserve adequacy, the underwriting cycle
is driven by many process-related factors
 Prior year(s) loss estimates
 Anticipated investment returns
 External environment
 Loss cost trend, inflation
 Shock losses
 Catastrophes
 Market conditions
 Terms and conditions
 Rate changes
 Underwriting criteria
 Reinsurance costs

Underwriting Cycle Observations –
Measuring the impact of price monitoring
 The a-priori estimate
 When do we find out the estimate is adequate
 Test with diagnostics
 Prior and subsequent years
 What happens when the estimate is too low/high
 Feedback mechanism
 Control cycle

 Challenges assumptions
 Reflects trends, stability, newly emerged claims
 Feedback loop
 Understand the “difference column”

Reserve Adequacy - Revisited
 External Influences
 Rating Agencies
 Regulatory
 RBC threshold testing
 Triennial reviews
 Statutory opinions
 Moved from opining on net reserves to include
identification of other potential factors
 SarbOx

 Schedule F
 Disputed Recoverables
 Note 33 (asbestos and pollution disclosure)
 Ceded Reinsurance Collateral
 Discounting Sensitivity (tabular plus non-tabular)
 Retroactive Reinsurance

Reserve Adequacy - Revisited
 Statutory Opinion Requirements
 Gross versus Net
 Material Adverse Deviation

Other Thoughts

Other Thoughts
 Reserving Actuary as business partner
 Part of control mechanism and feedback loop
 Reserving process and therefore pricing process can
incorporate
 Claims department
 Reinsurance accounting
 Pricing and underwriting
