Value Added Tax Loss Of Incentive Description |  |  |  |  |  |  | "Desenvolve" is an incentive remaining from Brazil's hyperinflationary days about 10 years ago. It is based on the net ICMS (VAT) tax payable. (QT pays ICMS to suppliers on raw materials, bills and collects ICMS from customers, takes credit for ICMS paid to suppliers and remits the difference. The net amount payable is payable 30% immediately and 70% for up to five years. The "desenvolve" is an incentive to pay the 70% quickly, like a cash discount. If the full amount is paid immediately, there is an 80% discount of the 70% (or 56% of the total). |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
