YIT'S COMPARISON FIGURES FOR 2009 IN ACCORDANCE WITH THE NEW IFRS INTERPRETATION


YIT CORPORATION    STOCK EXCHANGE RELEASE    MARCH 23, 2010 at 8 a.m.           


YIT'S COMPARISON FIGURES FOR 2009 IN ACCORDANCE WITH THE NEW IFRS INTERPRETATION

YIT will apply the IFRIC 15 Agreements for the Construction of Real Estate IFRS 
interpretation from the start of the financial period beginning on January 1,   
2010. The adoption of the new interpretation will have an impact on certain     
items of the consolidated income statement, balance sheet and cash flow         
statement and the key figures based on them. The adoption of the interpretation 
will not have any impact on the figures covering YIT's segments published by the
Group as the information will continue to be calculated in accordance with      
existing accounting principles.                                                 

The IFRIC 15 interpretation contains guidelines on when the revenue generated by
the construction of real estate must be recognised on the basis of the handover 
of the building and when the percentage of completion method can be applied. In 
YIT, the new interpretation will have an impact on the recognition of           
development projects involving residential and commercial real estate. The      
interpretation will not have any impact on construction contracting or building 
and industrial services.                                                        

Under the new practice, the quarterly revenue and profits of the YIT Group will 
now fluctuate more in accordance with the completion dates of building projects.
The consolidated balance sheet total will be higher, while at the same time the 
key figures calculated from the balance sheet will weaken. The new revenue      
recognition practice also means that it will take more time for the Group's     
financial figures to reflect changes in production volumes.                     

MAIN CHANGES                                                                    

Project revenue recognition                                                     

In the future, the revenue generated by YIT's own residential development       
projects will be recognised in Group-level reports when the project is complete 
i.e. when the residential units are ready to be handed over to the client. The  
share of income and expenses to be recognized will be calculated also in the    
future by multiplying the percentage of completion by the percentage of sale.   
Under the old practice, the revenue recognition began when the building work    
started using the percentage of completion method.                              
                                                                                
In YIT's own commercial real estate development projects, the recognition       
practice will be evaluated on a case-by-case basis and in accordance with the   
terms and conditions of each contract. In the future, the projects already sold 
will be recognised when the construction work has started or when the project is
complete. The share of income and expenses to be recognized will be calculated  
also in the future by using the formula percentage of completion multiplied by  
the percentage of sale multiplied by the occupancy rate. Under the old practice,
the recognition of sold projects was possible to start always immediately when  
the building work started. YIT usually sells its commercial real estate         
development projects to investors before the start of construction or during the
early stages of the construction work, which together with other facts means    
that in most cases the revenue of these projects can be recognised in accordance
with the old practice also in the future.                                       

Consolidated income statement and order backlog                                 

In the consolidated income statement, the new interpretation will affect the    
revenue, operating profit and profit before taxes. There will be no changes in  
the reporting of financial expenses. There will be no material changes in the   
tax rate but the change in the timing of revenue recognition will affect the    
deferred taxes. By changing the revenue recognition practices, the new          
interpretation will also have an impact on the Group's order backlog which      
covers the portion of the customer orders and ongoing own development projects  
that has not been recognised as revenue.

Consolidated balance sheet                                                      

The most important reporting change concerning the consolidated balance sheet is
that YIT's production to which the new rule applies will be reported as part of 
current assets and the payments received from the customers in advances received
until the completion of the project - i.e. until the moment it will begin to be 
recognised as revenue. As a result, there will be an increase in current assets,
advances received and the balance sheet total.                                  

In Finland, YIT finances its projects by selling construction-stage contract    
receivables to financing companies. According to the new interpretation, sold   
residential units from own development projects will be recognised as revenue   
when the project is complete. As a result, all construction-stage contract      
receivables related to residential production and sold to financing companies   
must be reported as part of the interest-bearing liabilities on the balance     
sheet. Under the old practice, part of construction-stage contract receivables  
related to residential production was reported as off-balance sheet items.

Consolidated cash flow statement                                                

Under the new interpretation, all sold residential units from own development   
projects will be recognised as income after the project is completed. As a      
result, the all cash flow connected with construction-stage contract receivables
will in the future be reported as part of the cash flow from financing          
activities. Under the old practice, the proportion of the construction-stage    
contract receivables directed at sold residential units was reported as part of 
the cash flow from operating activities.                                        

The reporting of the net change in cash and cash equivalents and their amount at
the end of the period will not be affected.
