In support of the overall ISDA 2021 Definitions initiative, the new FpML Version 5.12 and the legacy FpML Version 4.2, include the following changes:

• The new cash settlement methods included in the ISDA 2021 Definitions, such as the mid-market valuation and the replacement value methods.
• Modular daily calculated rates e.g. lookback compounded and observation period shift calculation rates, that are being developed for the 2006 Definitions and included in the 2021 Definitions.
• Defining fallback rates to help facilitate internal Straight Through Processing.

In addition, Version 5-12 includes several new fields to better support CFTC Amendments to Part 45 regulatory reporting and Loans enhancements.

• ISDA is introducing new Definitions to address changes in the market, and FpML is supporting that by

• Creating new versions of the standard to support new features such as new cash settlement methods, modular calculated rates, and fallback rates

• Updating reference data to support the new types of floating rate indexes that are being developed

• Helping developers to understand how to support the changes
