"Management's assumptions regarding the full year 2009 average exchange rates
used in preparing this guidance have decreased from 3.20-3.30 PLN/USD to
3.10-3.20 PLN/USD and from 32.00-33.00 RUR/USD to 31.50-32.50 RUR/USD."

As you can see the management assumption is probably the worst case scenario and this is what they based the estimates on. In reality the picture looks much better.
