B3 has implemented a change to the “expiration code” field in the shortened version of the BVBG.031 (DailyFeeUnitCostReport) file, which is used to inform market participants about the unit costs of fees applicable to trades. From now on, the shortened version, sent to options markets 3 and 4, will only include the month code and the year code, thus reducing the file size. Previously, this field also contained the option type and an alphanumeric sequence. This change was made to accommodate clients who were experiencing difficulties with the current file size.

Following the implementation the Private Securities Post-Trade Solution (Flow II), B3 identified the need to increase the number of decimal places in the “price” and “quantity” fields from 6 to 8, in the case of Closed-End Fund Shares (CFF) trades. We will therefore adjust the allocation process carried out in Real Time Clearing (RTC) to the flow of the previously existing product. Therefore, these trades can also be allocated through the new solution, which will now have full adherence to the products already integrated with it, namely, Debentures, Real Estate Receivables Certificates (CRI), Agribusiness Receivables Certificates (CRA) and Closed-End Fund Shares (CFF).

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.
