This library is a C# implementation of the following Initial Margin models for non-cleared derivatives transactions:

Both models can handle Post and Collect regulations through a worst-of approach and Initial Margin values can be calculated by role (Pledgor and Secured). Model mixtures are handled too, which means that a single dataset can define both SIMM™ and Schedule data entities in order to produce two distinct Initial Margin values. On the top of that, the framework is compatible with Common Risk Interchange Format (CRIF™) files.


This library has been created for educational purposes. Users who are interested in calculating Initial Margin values using SIMM™ for commercial activities must contact ISDA in order to validate its output against a unit test and obtain a license.

Main Features

InitialMargin is...

  • Easy-to-Deploy: all what it requires is compliant input data, either in the form of a CRIF file or as a runtime-generated list of data entities;
  • Easy-to-Maintain: periodic updates to Initial Margin models are easy to integrate and require only minor changes to the library algorithms;
  • Stable: the library implements strong data validation routines and a very detailed exception handling framework.


The library is os-agnostic (it has been developed under .NET Standard 2.0) and platform-agnostic, (both x86 and x64 environments are supported). The project targets Visual Studio 2017.
