In 2016, ISDA launched the ISDA SIMM Crowdsourcing Utility, operated by ICE Benchmarks Administration, to harmonize certain firm level inputs to the ISDA SIMM to reduce disputes in initial margin calls.  As more firms prepare for compliance with regulatory initial margin requirements in 2018, 2019 and 2020, ISDA encourages firms to engage in early preparation for the use of SIMM, including participation in the ISDA SIMM Crowdsourcing Utility.   For additional information, contact IBA@theice.com.
