10. Growth of access revenues (+1% Q on Q) limited by strong reduction in marketing expenditure (-66%) and by some special access offers in Germany which have now been terminated. Growth in minutes’ traffic was about 10% in the quarter Portal revenues, including advertising sales, continue to increase rapidly (+18%) even in a declining European market Reduction in low margin voice sales in line with our strategy and expectations Keeping our promises for reduction in G&A/personnel costs B to B sales are down 25% from the previous quarter due to a revenue peak in Q4 00 and in particular to the demands of the integration process in Q1 01.
