Unanticipated changes in risk factors can affect reserves. As an indicator of the causal effect that a
change in one or more risk factors could have on reserves for workers’ compensation, a 1% increase
(decrease) in incremental paid loss development for each future calendar year could result in a 1.3%
increase (decrease) in claims and claim adjustment expense reserves.
Historically, the one-year change in the reserve estimate for this product line over the last nine
years has varied from 1% to 2% (averaging 0%) for the Company, and from 1% to 4% (averaging
1%) for the industry overall. The Company’s year-to-year changes are driven by, and are based on,
observed events during the year. The Company believes that its range of historical outcomes is
illustrative of reasonably possible one-year changes in reserve estimates for this product line. Workers’
compensation reserves represent approximately 33% of the Company’s total claims and claim
adjustment expense reserves.
The Company’s change in reserve estimate for this product line was 0% in 2011, 1% in 2010 and
1% for 2009.
Fidelity and Surety
Fidelity is generally considered a short tail coverage. It takes a relatively short period of time to
finalize and settle fidelity claims. The volatility of fidelity reserves is generally related to the type of
business of the insured, the size and complexity of the insured’s business operations, amount of policy
limit and attachment point of coverage. The uncertainty surrounding reserves for small, commercial
insureds is typically less than the uncertainty for large commercial or financial institutions. The high
frequency, low severity nature of small commercial fidelity losses provides for stability in loss estimates
whereas, the low frequency, high severity nature of losses for large insureds results in a wider range of
ultimate loss outcomes. Actuarial techniques that rely on a stable pattern of loss development are
generally not applicable to low frequency, high severity policies.
