      <subfield code="a">When calculating claims reserves, the market practice is to use development triangles, or modifications of this method. Recent research has suggested that non-triangle techniques are more accurate, especially for estimating reserver volatility. Estimation of Incurred But Not Reported (IBNR) for monitoring and pricing purposes often requires drilling down into data segments. Those estimations could significantly benefit from a non-triangle method. However, the market is reluctant to abandon triangle techniques, due to their satisfactory levels of accuracy and simplicity. This article examines a new triangle-free methodology for modelling IBNR claims, and explains how and where the method can be practically applied and its benefits.</subfield>
