5. Objective It is desirable to have a set of calibration standards that can be applied consistently to as wide a range of interest-sensitive insurance and investment products as possible, including both long and short term products. Mandate The working group has been formed to investigate and develop methodologies and standards for the calibration of interest rate models for determining reserves to be held by life insurance companies.

6. Scope In order to arrive at a set of standards that can be applied to at least some products within a reasonable timeframe, it may be necessary for the working group to limit the scope of its work to a few specific products for which complete calibration criteria can be more readily determined and leave the specification of calibration criteria for other interest- sensitive products as a future project, possibly for another working group.

8. Overview of the Calibration Framework  General Principles  Qualitative Criteria  Quantitative Criteria CLIFR Calibration of Interest Rate Models Working Group CIA Annual Meeting  Assemblée annuelle de l’ICA

9. General Principles Calibration criteria should: 1.Be sufficiently robust to narrow the range of practice, but allow the actuary to apply reasonable judgement to specific circumstances; 2.Be applied to the set of scenarios produced, not to the model parameters or inputs; 3.Be applied to not only the near term, but also the steady state portions of the scenarios produced; CLIFR Calibration of Interest Rate Models Working Group CIA Annual Meeting  Assemblée annuelle de l’ICA

10. General Principles (continued) 4.Be applied to more than one point on the yield curve including a mix of short, medium, and long-term points; 5.Promote the development of scenario sets that measure exposure to yield curve shocks as well as long-term paths of declining as well as rising interest rates, consistent with history; 6.Look at average rate distributions corresponding to extended periods of time as well as rate distributions at selected points in time.
