The CFO attributes our increased sales last year to the new markets in Eastern Europe. Nevertheless, a careful study of our revenue reveals a boom of sales in Southeast Asia, while the markets in Eastern Europe, after an early surge, settled at levels much lower than expected.

Current plans call for expansion into Eastern Europe, but the Southeast Asian markets hold much more promise.
