On September 2, 2015, the Committee on Payments and Market Infrastructures (CPMI) and the International Organization of Securities Commissions (IOSCO) issued a consultative report on the harmonization of the first batch of key OTC derivatives data elements (other than the unique transaction identifier (UTI) and the unique product identifier (UPI)).

The report focuses on a first batch of key data elements (other than UTI and UPI) that are considered important for consistent and meaningful aggregation on a global basis. The report provides information on the guiding principles adopted to develop the report and on the differentiation between first and second batch of data elements other than UTI and UPI. Also set out is the harmonization proposal in individual tables, data element per data element. The CPMI and IOSCO are working on a second batch of key data elements in parallel to this report.
