A change in the prevailing interest rates generally translates into a change in the fair value of our fixed income/maturity securities, and by extension, our overall book value. Market Risk and Duration We analyze potential changes in the value of our investment portfolio due to the market risk factors noted above within the overall context of asset and liability management.

Duration We analyze potential changes in the value of our investment portfolio due to the market risk factors noted above within the overall context of asset and liability management.
As a result, loss experience in the more recent accident years for the long-tail liability coverages has limited statistical credibility in our reserving process because a relatively small proportion of losses in these accident years are reported claims and an even smaller proportion are paid losses.

Duration is a measurement used to quantify our inherent interest rate risk and analyze our ability to match our invested assets to our reserve liabilities. If our invested assets and reserve liabilities have similar durations, then any change in interest rates will have an equal effect on these accounts.

We use catastrophe modeling and a risk concentration management tool to monitor and control our accumulations of potential losses in natural catastrophe exposed areas of the United States, such as the Gulf Coast and East Coast, as well as in areas of exposure in other countries where we are exposed to a portion of an insurer's underwriting risk under our assumed reinsurance contracts.

Estimates for workers' compensation are particularly sensitive to assumptions about medical cost inflation, which has been steadily increasing over the past few years. Other variables that we consider and that contribute to the uncertainty in establishing reserves for workers' compensation claims include: state legislative and regulatory environments; trends in jury awards; and mortality rates.

Other factors contributing to our development include: establishing reserves at their ultimate expected loss amount as soon as practicable after information becomes available, which produces, on average, conservative case reserves; using claims negotiation to control the size of settlements; assuming that we have liability for all claims, even though the issue of liability may, in some cases, be resolved in our favor; promoting claims management services to encourage return-to-work programs; case management by nurses for serious injuries and management of medical provider services and billings; and using programs and services to help prevent fraud and to assist in favorably resolving cases.

Each of the three methods produces an estimate of the ultimate ALAE cost for an individual accident year and the final estimate is generally a weighted average of the various methods. Inception to date paid ALAE is subtracted from the final ultimate ALAE estimate to provide the estimated ALAE IBNR reserve for each individual accident year.
Each of the three methods produces an estimate of the ultimate DCC cost for an individual accident year and the final estimate is generally a weighted average of the various methods. Inception to date paid DCC is subtracted from the final ultimate DCC estimate to provide the estimated DCC unpaid reserve for each individual accident year.
