Rollover of Commodities (Live Cattle - BR1, Corn - MR1, Soybean - SC and SO1, Ethanol - ET1 and Coffee - CR1) will now receive trade Execution Reports. Therefore, for each trade carried out, participants will receive 3 Execution Reports, one with the execution message and the agreed price of the structured rollover transaction and two additional Reports with confirmation of trades and prices of the instruments that make up the strategy legs. Furthermore, these contracts must follow the formulas for pricing the legs, as described below: Short leg: • Nature of Transaction: Different from the strategy transaction • Price: Price of the last short leg trade carried out at the time of transaction registration • Quantity: Same quantity as the strategy transaction Long leg: • Nature of Transaction: Identical to the strategy transaction • Price: Short leg price + strategy traded price • Quantity: Same quantity as the strategy transaction To accomplish this, the BR1, MR1, SC1 and SO1 contracts must have the short leg settlement price changed to the last traded price, as these contracts currently use the settlement price.

RTC – Inclusion of the field 'Change of executing participant' in the position transfer screen The new functionality will allow participants to also transfer the executing participant during position transfer if it is the same as the carrying participant at the origin of the trade. This functionality will be available via messaging through an optional field in file bvmf.028. At the end of the transfer process, the executing participant will be the same as the carrying participant.

We will expand the variety of data delivered in the SecurityList file, including registration data and debenture negotiation.

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%.
