A quote form the latest annual report gives some insight in to this issue.

"Given the size and concentration of the U.S. Market, our commercialization efforts are almost exclusively focused on that market. Our highly limited commercialization efforts in other regions in which the RECELL System is approved for sale is based on our assessment that the acute burn market inmany countries is proportionately less than the market in the United States, and the investments in a full marketing and sales resources and the effort to obtain reimbursement are not justified until we have obtained pivotal clinical results in additional indications. In Australia and Europe we no longer actively promote the RECELL System and have limited our commercialization efforts to filling sales orders as received from a small group of customers who have already been trained to use the product. As additional pivotal trial data for the RECELL System is generated in additional indications, we mayseek to commercialize the RECELL System in countries outside the United States through a combination of collaborations and direct efforts, dependingupon the territory and the indication."
