ANNEX: 1 Sheet

61.1. PARTIAL RECTIFICATIONS 61.1.1. General Instructions Information may be submitted by accessing the website (https://www3.bcra.gob.ar) and logging in with the single user code and password per entity, as provided in Section 1 of the Submission of Information to the Central Bank, according to what is established for the www3 file transfer service (MFT). In the case of financial entities, non-financial credit providers, financial trusts, and peer-to-peer credit service providers through platforms, a file named “RECTPARC.TXT” will be recorded, while mutual guarantee companies and public guarantee funds will record a file named “RECTPARCSF.TXT”. One file may be submitted per day containing a maximum of 250 records. To identify this regime/requirement (61.1. PARTIAL RECTIFICATIONS), the regime code “00002” and requirement code “00005” shall be used for financial entities, non-financial credit providers, financial trusts, and peer-to-peer credit service providers through platforms; or the regime code “00002” and requirement code “00011” for mutual guarantee companies and public guarantee funds. A record must be reported for each information period that corresponds to being deleted or rectified from the records of each debtor. This plain text file will be of variable length, according to the corresponding record design, taking into account the following specifications: a. Character encoding ANSI-1252 must be respected. b. The symbol “;” (semicolon) will be used as a field separator. c. To separate each record, the TXT file generation application used by the entity must symbolically include the hexadecimal characters representing a <CR> “Carriage Return” and a <LF> “Line Feed”. This means that an <Enter> is generated at the end of each record. d. The last field of each record MUST NOT contain the “;” symbol at its end. That is, the number of “;” per record equals the expected number of fields minus 1. e. It is not necessary to fill the field up to the expected maximum length (i.e., filling numeric fields with leading zeros or alphanumeric fields with blank characters). f. If a field is not to be reported (value “NULL” or absence of value), the field separators (“;”) must be completed successively without intervening blank spaces. (Applicable exclusively for deletions). B.C.R.A. SUBMISSION OF INFORMATION TO THE CENTRAL BANK Section 61.
