Monte Carlo, Monaco ? The ATP men’s tennis circuit will pay prize money in Euros instead of U.S. dollars at its European tournaments starting next year.

The ATP said Wednesday that it had approved the use of a dual Euro/dollar currency system in recognition of the Euro’s strength and acceptance.

Next year, the ATP will publish prize money lists in both U.S. dollars and Euros. Tournaments in Europe will pay in Euros, while U.S. events will pay in dollars. All other tournaments must choose by the end of this month whether to pay in Euros or dollars.
