Description: In 2007 the International Accounting Standards Board IASB released a discussion paper proposing a new accounting model for insurance contracts, known as the current exit value model. One aspect of the proposed accounting model is that claim liabilities would need to include explicit margins satisfying certain criteria. Currently it is common for U.S. medical insurers to include explicit margins in their claim liabilities. However, we demonstrate that the margin approach most commonly used today by U.S. medical insurers does not satisfy the objectives articulated in the IASB discussion paper regarding the role of margins. We then propose a new formula for including explicit margins in U.S. medical insurance claim liabilities in a manner that is more compatible with the principles articulated in the IASB discussion paper. Finally, we illustrate our proposed claim liability formula using an example drawn from real-life data.
