I need support with this Business question so I can learn better.

Suppose a U.S. wood-products company has facilities and employees in Canada providing its raw materials (wood), but has most of its sales in the United States.

(1) What are the most important operational and financial risks in this arrangement? (2) How can the company pay its Canadian employees, who presumably want Canadian dollars, when its U.S. customers are paying in U.S. dollars? Furthermore, how can it calculate its profit if revenue is in U.S. currency and most of its costs are in Canadian currency?
