- Order backlog increased by 21 per cent to EUR 3,627.0 million (EUR 2,995.4 million).
- Number of personnel at the end of March was 23,644.

We estimate that the revenue and profit before taxes for 2008 will increase compared to the previous year.
The estimate has not been changed since the publication of the Financial Statements Bulletin.

- The Group's profitable growth continued. Building Systems is the largest segment by personnel and revenue and it also generates a considerable proportion of operating profit. Increasing the profitability of Building Systems continued strongly. With regard to our geographic areas of operations, Russia grew at the fastest rate. The profitability of International Construction Services remained good with a strong growth in revenue, despite the weakening of the Baltic market. In Construction Services Finland business premise and infrastructure construction continued stable while housing construction slowed down. In housing production we made a decision that all YIT Homes in Finland will be built as low-energy houses. Industrial Services developed at a steady rate. The strengthening of the order backlog in all segments provides a favourable starting point for the future, says President and CEO Hannu Leinonen.
