it's not a dividend; it's a statutory pmt of interest on capital and it is one time. the announce date was 4/3 but am never sure if the announcement and the ex-dates coincide for these pmts in Brazil. the payment date is 4/25 so for purposes of the ADR, that may be the ex-date or T+3 as that is the limit in which the custodian has to distribute to ADR holders. the record date is 4/2 but, again, not sure how that applies to ADR holders based on my experience. bottom line: that they've announced the date of payment could suggest some volatility in the ADR - in particular on Monday as the Bovespa will remain closed.
