(6)Resolução BCB 3.263/05 does not set any obligations to perform portfolio compression nor does it frame any recommendation to do so. It does however make it possible for financial institutions and other institutions supervised by the BCB to enter into an agreement allowing it. There is no specific legislation regarding dispute resolution processes. Dispute resolution rules are determined by the trade repositories. Therefore, Brazilian arrangements may not be deemed equivalent to Union requirements in respect to portfolio compression and dispute resolution.
