Metro Ltd is a company which distributes and sells decorative trains for display. The company, which is based in Australia, imports the decorative trains from the USA which it packages and sells in New Zealand and larger countries in the Far East. The company is also considering establishing a subsidiary in South Africa which would buy products from Metro Ltd and sell within Africa. Metro Ltd reports its results in its home currency. The company pays for its purchases from the USA in US dollars, but receives payment for the goods which it sells in Australia and the Far East in local currency. All transactions carried out with the subsidiary in South Africa would be in US dollars. The company generally takes $6$ weeks to pay its supplier in the USA and receives payment from debtors within $4$ months.

Over the last few years the company has found that sales have been quite predictable and it has been possible to plan sales levels and purchases of goods in advance. However, there is increasing competition from companies in the Far East, which may make this more difficult in the future.
