The amount depends on the export level. For example, for a purchase of $100 million made in the United States this year, the amount would be less if the same purchase had totalled $150 million last year. It depends on export levels. It is a matter of arithmetic.
This year, exports are lower than usual, lower than last year. Under this arrangement, they are probably at the lowest level. However, at the same time, this arrangement works very well with the banks, that is, very smoothly.
