| Calendar year | Pre-tax catastrophe losses |
| 2006 | $287.9 | million |
| 2005 | $1,485.7 | million |
| 2004 | $390.0 | million |
| 2003 | $35.0 | million |
| 2002 | $30.0 | million |
our losses from future catastrophic events could exceed our projections. we use projections of possible losses from future catastrophic events of varying types and magnitudes as a strategic under- writing tool. we use these loss projections to estimate our potential catastrophe losses in certain geographic areas and decide on the purchase of retrocessional coverage or other actions to limit the extent of potential losses in a given geographic area. these loss projections are approximations reliant on a mix of quantitative and qualitative processes and actual losses may exceed the projections by a material amount. we focus on potential losses that can be generated by any single event as part of our evaluation and monitoring of our aggre- gate exposure to catastrophic events. accordingly, we employ various techniques to estimate the amount of loss we could sustain from any single catastrophic event in various geographical areas. these techniques range from non-modeled deterministic approaches 2014such as tracking aggregate limits exposed in catastrophe-prone zones and applying historic dam- age factors 2014to modeled approaches that scientifically measure catastrophe risks using sophisticated monte carlo simulation techniques that provide insights into the frequency and severity of expected losses on a probabilistic basis. if our loss reserves are inadequate to meet our actual losses, net income would be reduced or we could incur a loss. we are required to maintain reserves to cover our estimated ultimate liability of losses and loss adjustment expenses for both reported and unreported claims incurred. these reserves are only estimates of what we believe the settlement and adminis- tration of claims will cost based on facts and circumstances known to us. in setting reserves for our reinsurance liabilities, we rely on claim data supplied by our ceding companies and brokers and we employ actuarial and statistical projections. the information received from our ceding companies is not always timely or accurate, which can contribute to inaccuracies in our 81790fin_a 4/13/07 11:08 am page 23 http://www.everestre.com.
