The Spanish group Amadeus, a world leading technology provider for the travel and tourism industries, posted on Friday a jump of 657 percent in 2011 net profit, owing to one-off effects.
The group's net profit of 453.7 million euros ($607 million), came in large part as a result of a favourable comparison with 2010, when Amadeus returned to the stock market with a 1.3-billion-euro listing after a five year absence.
When exceptional items were stripped out, the group's net profit showed a more modest gain of 20.8 percent to 487.2 million euros, a statement said.
Amadeus has benefited this year from a rebound in international tourism.
