Special Notice

Over the last couple weeks, based on feedback from our users and internal investigations, we have conducted a major overhaul of the entire model. With these updates now completed, we have now released version 3.0 of E-CHAIM. Because of the breadth of updates we ask all users to update their local versions of E-CHAIM to the latest version. Prior versions of the model, and more particularly their model databases, will no longer be supported after October 1st, 2020.
