The percentage under each amount is that payment divided by the closing price on the last day to qualify (Brazil's data-com; on a holiday, the previous session). It shows the size of the payment on that day; it says nothing about future ones.
The link opens the company's filings in the period (30 days before the ex-date up to 7 days after); we do not state which one is about this payment. Read the primary source. There is no link for REITs.
