B3 will implement an optional field in securities lending to provide custodians with visibility of the give-up participant ID for executed trades. The information will provide greater transparency and speed up the validation of orders entered by managers. It will be available both via message and on the electronic trading platform, streamlining and improving the validation of offers. For technical details, see the catalog on the project page.

Currently, some rollovers have a differentiation in Tag 762 (e.g. Tag 762 = 140 – Financial Rollover, 141 Agricultural Rollover, etc.) identifying the different types of rollovers while EDSs only come with Tag 762 = 90 – Strategy, without this distinction. Therefore, we will include a characterization domain, for example (Tag 762 = xxx – DV01 Neutral and UP Neutral).

Specific enhancements for the 2024 peak season include new treatment for votes originating from the same investor and custodian, which were previously rejected for duplicity. Performance improvements were also implemented to generate the vote map. In addition, B3 made improvements to the CICORP system, including an adjustment to minimize errors when selecting ISIN numbers during Distance Voting Bulletin (BVD) registration. None of these changes require market adaptations.
