предлоги и общий смысл в тексте контракта

проблемы касаются части the customers have the right to offset the amounts payable to the SPV following the sale of the loan portfolio, against any monetary claims that they may have against the Originator

так? или совсем не так?

подскажите, пожалуйста, буду благодарна
