That important metric actually understates their sales due to the strength of the US Dollar this last year. On a constant-currency basis, it is about 15% higher. Just goes to show the 'real' results are even more impressive.
Maybe sales were over-stated in the decade prior due to weakness in the US dollar? I don't understand the meaning of picking a favourable exchange rate to normalize the earnings.
For all we know, it's high dollar from here to eternity.
