In the Securities Lending Subscription process, the "End Date", which refers to the last day for returning subscription rights from borrower to lender, will be removed from the RTC - Subscription Management Module screen. There will be no change to the Subscription Surplus event.  The BVBG.098 file will undergo changes where the respective field becomes optional.

Improvement of the UDS interface will occur when strategies with Options are created. Previously, users had to enter all relevant option data ("Expiration", "Underlying Asset", "Type" and "Strike Price") so that the option ticker could be generated by the system. With the implementation of this improvement, users will only need to enter the option code in the specific field on the strategy creation screen. This will lead to automatic filling with all the data needed to create the UDS. However, the "C/V" (call or put) and "QtdLote" (quantity) fields must be completed. With the change, the "Code" field will be repositioned to the left of the screen, right after the "Market" field.

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).
