PRAGUE (ÈIA) – Seasonally adjusted revenues in services stagnated in Q4 of 2011 compared with the previous quarter. After adjustments, revenues fell 2.2%, and if not adjusted, the decline was 2.6%. The overall development was mostly affected by lower sales in professional, scientific and technical activities (- 9.6%). Revenues in transport and warehousing increased 1.1% on the year, primarily thanks to higher revenues from ground and tubular transport (+ 1.4%) and air transport (+ 3.4%), according to the figures published by the Czech Statistical Office (ÈSÚ).
