Implementation of general improvements in the repurchase option flow for Financial Bills (LFs).

Insertion of Delta and MTM data for Centrally-Cleared Options in the G015 file. The goal is to share these parameters with clients so that they can use them to replicate internally in pricing engines, among other purposes.

Based on this improvement, when applying filters on CVA screens the filter’s composition will be displayed at the top of the screen, so that the filtered data is displayed and known during use. With this vision, operational processes will be faster and opening the filter box for verification will no longer be necessary. This is similar to what is used today in RTC. With this improvement, users will have better and more user friendly screen usability. The display of the applied filter will facilitate operational verification and data reading adding greater transparency to the process.

A subscription right is when a company decides to increase its capital by issuing new shares. In this situation, the company's shareholders have preference right to purchase the assets in the new lot. Currently, the posting of subscription rights (transfer of rights from the Company's Registration Book to B3’s environment) is carried out entirely manually with physical documents sent to B3, which makes the whole process time-consuming and with a lead time of approximately 3 days. Through this initiative, we intend to automate the entire flow, providing process autonomy to requesters while eliminating operating risks and physical documentation flows. Furthermore, lead time will be reduced by 60%.

B3 created an automatic Income Tax (IR) withholding transaction for CFF – Closed-End Fund Shares. If the IR withholding transaction for CFF is entered before 10.00 AM, the event settlement message will be sent in Gross settlement mode with the tax amount already withheld.  On the other hand, if the IR withholding transaction is entered after 10:00 AM or the event is entered in T0, the flow will be the same as that currently adopted. In other words, two messages will be generated: one with the full amount of the event and one with the amount to be withheld from IR.

At the end of the transfer process, the executing participant will be the same as the carrying participant.
