YIT CORPORATION      STOCK EXCHANGE RELEASE     MARCH 17, 2010 at 9.00 A.M.     


PUBLISHING OF COMPARISON FIGURES COMPLIANT WITH NEW IFRS INTERPRETATION ON MARCH
23                                                                              

YIT will apply the IFRIC 15 Agreements for the Construction of Real Estate IFRS 
interpretation as of the financial period starting January 1, 2010. The         
interpretation provides guidance on when to account for revenue from the        
construction of real estate based on delivery and when the percentage of        
completion method can be used. The interpretation will change the recognition of
YIT Group's development projects in both housing and business premises and thus 
have an effect on certain Group level figures. The interpretation will not have 
an effect on business segment figures, as they are accounted using the previous 
accounting principles also in the future.     
                                  
YIT will publish comparison figures for the financial year 2009 compliant with  
the new accounting principles on March 23, 2010 at 8 a.m. Finnish time (EEST).  
The stock exchange release and presentation materials will be published at that 
time on the company's website at www.yitgroup.com/investors.
