[经] 回购或互购
Article 7 The categories of securities for trading shall include purchase, sale and counterpurchase. 第七条债券交易种类包括买卖和回购。
Switch trading occurs when a third-party trading house buys the firm's counterpurchase credits and sells them to another firm that can better use them. 在转手贸易中，贸易中介买下该公司的互购信用并将其出售给另一个可以更有效使用该信用的企业。
Offset is similar to counterpurchase insofar as one party agrees to purchase goods and services with a specified percentage of the proceeds from the original sale. 一方同意将初始销售所得的一定比例用于购买另一方的产品和劳务。在这一点上，抵消贸易与互购是相似的。
