YIT'S Interim Report January 1 - September 30, 2010


YIT CORPORATION         INTERIM REPORT       October 27, 2010 at 8:00 a.m.      

YIT'S Interim Report January 1 - September 30, 2010:	                           
SUCCESSFUL SHIFT OF FOCUS TO RESIDENTIAL DEVELOPMENT PROJECTS IMPROVED          
PROFITABILITY IN FINLAND - FOURTH QUARTER ESTIMATED TO BE THE STRONGEST OF THE  
YEAR                                                                            

SEGMENT-LEVEL REPORTING 1-9/2010 (1-9/2009)  
Operating profit for January-September 51% higher than in previous year         
The operating profit of the segments was 51 percent higher than in previous year
amounting to EUR 159.4 million (1-9/2009: EUR 105.8 million). Operating profit  
was clearly higher than the previous year in Construction Services Finland, with
the focus of operations being shifted to residential development projects.      
Operating profit also improved in International Construction Services. In       
Building and Industrial Services the operating profit fell short of the year    
before due to the low level of new investments by the customers.                
The revenue of the segments increased by 7 percent compared to previous year and
was EUR 2,659.4 million (1-9/2009: EUR 2,491.8 million). Revenue increased      
across all segments.                                                            
The order backlog of the segments at the end of September increased by 20       
percent on the previous year to EUR 3,366.9 million (9/2009: EUR 2,800.8        
million). As a result of an acquisition completed in Central Europe in August,  
the Group's order backlog at the end of September increased by EUR 306 million. 

Segment-level reporting 7-9/2010 (7-9/2009)                                     
The operating profit of the segments was 27 percent higher than in previous year
amounting to EUR 57.9 million (7-9/2009: EUR 45.6 million). The operating profit
of Building and Industrial Services was burdened by non-recurring expenses      
amounting to a total of approximately EUR 3.3 million associated with           
acquisitions.                                                                   
The revenue of the segments increased by 13 percent compared to previous year   
and was EUR 924.2 million (7-9/2009: EUR 815.0 million).                        

Construction Services' focus on residential development projects                

YIT's goal is to be a forerunner in residential construction in all of its      
market areas - Finland, Russia, the Baltic countries and Central Eastern Europe.
During 2010, the focus of residential construction in Finland has been          
successfully shifted to residential development projects sold directly to       
consumers, and the number of rental housing project start-ups has decreased     
compared to the year before. In January-September, YIT started the construction 
of a total of 4,875 residential units built as development projects, of which   
2,003 in Finland (1-9/2009: 954), 2,543 (1-9/2009: 105) in Russia and 329       
(1-9/2009: 0) in the Baltic countries and the Czech Republic, where YIT started 
its first residential project.                                                  

Residential start-ups are responding to the continued favourable demand among   
consumers and keeping the number of apartments for sale sufficiently high.      
During January-September, YIT has sold a total of 1,412 residential units       
directly to consumers in Finland (1-9/2009: 1,057), of which 435 residential    
units in July-September. In Russia, YIT has sold a total of 2,216 residential   
units during the year (1-9/2009: 1,646), of which 717 residential units in      
July-September. In Finland, YIT has also become more active in the business     
premises market, which is showing signs of picking up.                          

YIT's target is to start the construction of approximately 1,000 residential    
units in October-December 2010 in International Construction Services covering  
Russia, Baltic countries and Czech Republic and Slovakia.                       

Acquisition in Central Europe increased building system services                

The acquisition of the Caverion Group, a provider of technical building system  
services in Central Europe, was agreed in June and completed at the end of      
August. Approximately 2,000 employees joined YIT. The integration of companies  
and the development of operations have started in line with the plans.          

The Group's strategic target is to increase building system and industrial      
service and maintenance operations in the Nordic countries and Central Europe.  
Service and maintenance accounted for 60 percent of the revenue of Building and 
Industrial Services in January-September (1-9/2009: 54%), or EUR 950.5 million  
(1-9/2009: EUR 833.9 million).                                                  

GROUP REPORTING (IFRIC 15) 1-9/2010 (1-9/2009)                                  

Due to the new recognition principles adopted at the beginning of 2010 the      
Group-level figures fluctuate greatly between different quarters. According to  
the recognition principle, residential development projects are only recognised 
in Group-level figures when the project has been completed, while in segment    
reporting they are recognised already as construction progresses. Both in       
Finland and in Russia, the number of completed units in residential development 
in January-September 2010 was considerably lower than in the previous year - in 
Finland 559 (1-9/2009: 1,029) and in Russia 940 (1-9/2009: 2,461).              
Group revenue remained at the previous year's level, amounting to EUR 2,449.6   
million (1-9/2009: EUR 2,460.3 million).                                        
Group profit before taxes increased by 45 percent from the previous year to EUR 
81.6 million (1-9/2009: EUR 56.4 million).                                      
The Group's earnings per share increased by 62 percent from the previous year to
EUR 0.47 (1-9/2009: EUR 0.29).                                                  
The Group's return on investment was 10.6 percent (9/2009: 11.1%) and the equity
ratio was 29.2 percent (9/2009: 28.2%).                                         

In the end of September, YIT had a total of 10,669 residential units under      
construction in all the countries where it operates. Especially in Russia,      
significantly more residential units will be completed during October-December  
than in January-September 2010, and the Group's revenue and profit will         
therefore be considerably emphasised during the fourth quarter. Completion of   
the projects requires commissioning by the authorities.                         

Outlook for 2010: Fourth quarter will be the strongest quarter of the year      

YIT Corporation estimates that the Group's (IFRIC 15) revenue will increase and 
profit before taxes will increase significantly in 2010 compared with 2009. YIT 
estimates that the Group's fourth quarter revenue and profit before taxes will  
be the strongest of the year. (The outlook for the fourth quarter has been      
specified.)                                                                     

KEY FIGURES                                                                     

YIT has applied the IFRIC 15 Agreements for the Construction of Real Estate IFRS
interpretation from the start of the financial period begun on January 1, 2010. 
Due to the application of the interpretation, Group-level reporting and         
segment-level reporting differ. The difference between the accounting policies  
is reported as an IFRIC 15 adjustment.

APPLICATION OF A NEW IFRS INTERPRETATION FROM JANUARY 1, 2010                   

YIT has applied the IFRIC 15 Agreements for the Construction of Real Estate IFRS
interpretation from the start of the financial period begun on January 1, 2010. 
Due to the application of the interpretation, Group-level reporting and         
segment-level reporting differ. The key difference is that residential          
development projects are only recognised in Group-level figures when the project
has been completed, while in segment reporting they are recognised already as   
construction progresses. The difference between the accounting policies is      
reported as an IFRIC 15 adjustment.                                             

YIT published the comparison figures for the financial year 2009 calculated on  
the basis of the IFRIC 15 interpretation in a stock exchange release on March   
23, 2010. The effects of the application of the interpretation on the figures   
have been explained in more detail in the notes to this Interim Report.         

GROUP'S FINANCIAL DEVELOPMENT                                                   

The Group's financial performance is presented with both figures compliant with 
Group-level reporting and figures compliant with segment-level reporting,       
referred to as the segments' result or segments total figure. The figures for   
2010 and 2009 are comparable.                                                   

SEGMENTS' REVENUE INCREASED SLIGHTLY                                            

The revenue of YIT's segments increased by 7 percent in January-September       
compared to the previous year, amounting to EUR 2,659.4 million (1-9/2009: EUR  
2,491.8 million). Changes in foreign exchange rates increased revenue by EUR    
103.6 million compared to the corresponding period last year.                   

The majority of revenue was generated in the Building and Industrial Services   
segment. The segment's revenue remained at the previous year's level during     
January-September. During the third quarter, revenue was higher than the        
previous year. Due to seasonality of the business, the third quarter is         
typically weak in Building and Industrial Services.                             

In International Construction Services revenue increased considerably in        
January-September compared with the previous year and it also increased in      
Construction Services Finland.                                                  

Following the IFRIC 15 adjustment, YIT Group's revenue remained at the previous 
year's level and was EUR 2,449.6 million for January-September (1-9/2009:       
2,460.3 million). The completion schedules of development projects affect the   
revenue recognition of the Group. Therefore, Group-level figures fluctuate      
greatly between different quarters. Both in Finland and in Russia, the number of
completed units in residential development in January-September 2010 was        
considerably lower than in the previous year - in Finland 559 (1-9/2009: 1,029) 
and in Russia 940 (1-9/2009: 2,461). YIT has a total of 10,669 residential units
under construction in all the countries where it operates. Especially in Russia,
significantly more residential units will be completed during October-December  
than in January-September 2010. Completion of the projects requires             
commissioning by the authorities.                                               

Revenue, EUR million

--------------------------------------------------------------------------------

In January-September 2010, Finland accounted for 44 percent (1-9/2009: 48%) of  
the Group's revenue, Sweden for 16 percent (1-9/2009: 15%), Norway for 14       
percent (1-9/2009: 12%), Central Europe for 12 percent (1-9/2009: 11%), Russia  
for 8 percent (1-9/2009: 7%), Denmark for 4 percent (1-9/2009: 4%) and the      
Baltic countries for 2 percent (1-9/2009: 2%).                                  

Service and maintenance operations generated EUR 994.9 million (1-9/2009: EUR   
874.3 million), or 41 percent (1-9/2009: 35%) of the Group's total revenue. The 
majority of the Group's service and maintenance operations are related to       
building systems and industrial processes in the Nordic countries and Central   
Europe, and part to road maintenance in Finland. Service and maintenance        
operations in Building and Industrial Services increased compared with the      
previous year.                                                                  

PROFIT AND PROFITABILITY OF THE SEGMENTS IMPROVED                               

The operating profit of YIT's segments increased by 51 percent to about EUR     
159.4 million (1-9/2009: EUR 105.8 million). The operating profit margin        
calculated on the basis of the segment figures was 6.0 percent                  
(1-9/2009:                                                                      
4.2%).                                                                          

Profitability was improved by shifting the focus of operations on residential   
development projects in Construction Services Finland. The profitability of     
International Construction Services has improved through favourable development 
of residential sales and YIT's higher selling prices compared to last year.     

The operating profit of Building and Industrial Services fell short of the year 
before due to the low level of new building system and industrial investments.  
In addition, the operating profit in July-September 2010 was weakened by        
non-recurring expenses amounting to a total of approximately EUR 3.3 million    
associated with acquisitions. The profitability of the acquired businesses is   
weaker than YIT's earlier profitability.                                        

Residential development projects are only recognised in Group-level figures when
the project has been completed. Following the IFRIC 15 adjustment, the Group's  
operating profit remained at the previous year's level, amounting to EUR 103.7  
million (1-9/2009: EUR 104.8 million). The Group's operating profit margin was  
4.2 percent (1-9/2009: 4.3%).

EARNINGS PER SHARE IMPROVED                                                     

The Group's profit before taxes increased by 45 percent from the previous year  
to EUR 81.6 million in January-September (1-9/2009: EUR 56.4 million). Earnings 
per share increased by 62 percent to EUR 0.47 (1-9/2009: EUR 0.29).             

Financial expenses decreased compared with the previous year's comparison period
due to lower hedging costs of the ruble and a decrease in net liabilities, and  
generally lower interest rates. The Group's net debt increased during the third 
quarter and the overall interest rate increased slightly.                       

ORDER BACKLOG INCREASED DUE TO AN ACQUISITION                                   

The order backlog of YIT's segments was EUR 3,366.9 million million at the end  
of September (9/2009: EUR 2,800.8 million), increasing by 10 percent at the end 
of June, when it was EUR 3,067.4 million.                                       

An acquisition made in Central Europe increased the order backlog at the end of 
September by EUR 306 million in the Building and Industrial Services segment.   
The order backlog transferred in the acquisition has a lower margin than YIT's  
earlier order backlog. In Construction Services Finland, the order backlog has  
clearly grown compared to the previous year as YIT has started up new           
residential and business premises projects. In International Construction       
Services, the order backlog decreased slightly from the level at the end of June
due to the weakening of the ruble, which had an effect of EUR -69.9 million in  
the segment's order backlog in July-September.                                  

Following the IFRIC 15 adjustment, YIT Group's order backlog was EUR 3,727.5    
million at the end of September (9/2009: EUR 3,059.6 million).

NEGATIVE CASH FLOW FROM OPERATIONS IN THE THIRD QUARTER                         

In January-September, the Group's operating cash flow after investments amounted
to EUR -56.1 million                                                            
(1-9/2009: EUR 83.4 million), of which EUR -121.6 million                       
(7-9/2009: EUR 23,7 million) was generated in July-September. The operative cash
flow was negative in July-September due to expenditure on acquisitions and plot 
investments, an increase in development projects under construction as well as  
smaller advance payments in contracting.                                        

At the end of September, the Group's invested capital amounted to EUR 1,601.4   
million (9/2009: EUR 1,646.5 million), whereas it was EUR 1,582.7 million at the
end of June. Return on investment remained clearly weaker than the target level,
amounting to 10.6 percent for the last 12 months (9/2009: 11.1%). Invested      
capital is calculated by deducting non-interest bearing liabilities from the    
balance sheet total. The Group's balance sheet total at the end of September was
EUR 3,234.6 million (9/2009: EUR 3,041.6 million). In Russia, significant       
projects will be completed during October-December, which will decrease the     
Group's invested capital and balance sheet total.                               

Of the Group's invested capital 32 percent (9/2009: 35%), or EUR 509.7 million  
(9/2009: EUR 563.5 million), was invested in Russia. At the beginning of the    
year, invested capital invested in Russia amounted to EUR 557.6 million. The    
invested capital in Russia has decreased due to favourable residential sales. On
the other hand, exchange rate changes of the ruble increased the amount of      
capital invested in Russia by EUR 17.3 million in January-September. The Group's
capital invested in Russia is primarily accounted for by the International      
Construction Services segment.                                                  

GROUP'S FINANCIAL POSITION REMAINED GOOD                                        

The gearing ratio decreased compared with the previous year, amounting to 80.5  
percent at the end of September 2010 (9/2009: 92.9%). The equity ratio was 29.2 
percent (9/2009: 28.2%). Net financing debt decreased on the previous year to   
EUR 636.6 million (9/2009: EUR 674.4 million). Cash reserves amounted to EUR    
173.9 million (9/2009: EUR 245.8 million) at the end of September. The balanced 
business structure and financial position of the Group enable acquisitions and  
plot investments required by YIT's growth strategy. Dividends of a total of EUR 
50.0 million were paid in the second quarter in accordance with the resolution  
of the Annual General Meeting. During the third quarter of the year, YIT paid   
EUR 73.0 million for the shares in Caverion GmbH, acquired in Central Europe.   
The cash reserves of Caverion were EUR 48.0 million when it was transferred to  
YIT and thus the cash flow effect of the acquisition (net) was EUR -25 million. 

The capital structure was reinforced in March 2010 by establishing a bond       
programme of EUR 400 million, under which a EUR 100 million bond targeted at    
domestic investors was issued. The five-year bond carries an annual fixed rate  
coupon of 4.823 percent.                                                        

Net financial expenses decreased to EUR 22.1 million (1-9/2009: EUR 48.4        
million), or 0.9 percent (1-9/2009: 2.0%) of the Group's revenue. The exchange  
rate differences included in the net financial expenses, totalling EUR -6.5     
million (1-9/2009: EUR -22.5 million), consisted nearly entirely of the costs of
hedging debt investments in Russia. At the end of September 2010, EUR 180.1     
million of the capital invested in Russia comprised debt investments and EUR    
329.5 million were equity investments or similar fixed net investments.         

Financial liabilities amounted to EUR 810.5 million (9/2009: EUR 920.2 million) 
at the end of September, and its average interest rate was 3.4 percent (9/2009: 
3.3%). Fixed-interest loans accounted for 60 percent (9/2009: 51%) of the       
Group's financial liabilities. Of the loans, 35 percent (9/2009: 34%) had been  
raised directly on the capital and money markets. The maturity distribution of  
long-term loans is balanced.                                                    

The total amount of construction-stage contract receivables sold to financial   
institutions grew as residential development projects increased, amounting to   
EUR 165.6 million (9/2009: EUR 86.1 million). Of this amount, EUR 162.0 million 
(9/2009: EUR 74.8 million) is included in interest-bearing liabilities on the   
balance sheet and the remainder comprises off-balance sheet items in accordance 
with IAS 39. Interest expenses on receivables sold to financing companies       
amounted to EUR 1.6 million (1-9/2009: EUR 1.5 million) during the review period
and these are fully included in the financial expenses of the review period.    

Participations in the housing corporation loans of unsold completed residential 
units, EUR 23.9 million (9/2009: EUR 39.5 million) at the end of September, are 
included in interest-bearing liabilities. The interest on the participations,   
EUR 0.7 million (1-9/2009: EUR 2.0 million), is included in housing corporation 
charges and is thus booked in project expenses.                                 

CAPITAL EXPENDITURES AND ACQUISITIONS                                           

Gross capital expenditures on non-current assets included on the balance sheet  
totalled EUR 99.1 million (EUR 1-9/2009: 15.7 million) during January-September,
representing 4.0 percent (1-9/2009: 0.6%) of revenue. Investments in            
construction equipment amounted to EUR 6.7 million (1-9/2009: EUR 5.0 million)  
and investments in information technology to EUR 5.9 million (1-9/2009: EUR 5.0 
million). Other investments, including acquisitions, amounted to EUR 86.5       
million (1-9/2009: EUR 5.7 million). The revenue obtained through business      
acquisitions in January-September totals approximately EUR 500 million at an    
annual level.                                                                   

In June, YIT agreed to acquire the business operations of Caverion GmbH, a      
company providing technical building system services in Central Europe. In      
addition, YIT has implemented other, smaller business acquisitions in Building  
and Industrial Services during January-September.                               

In the International Construction Services segment, YIT increased its holding in
YIT Don to 100 percent in January and in YIT CityStroi to 75 percent in July. An
agreement entered into force after the review period whereby YIT acquired a 70% 
holding in the Slovakian construction company Reding a.s.                       

Business acquisitions and companies consolidated into the Group are discussed in
more detail in the notes to the interim report for January-September 2010 and   
under events after the review period.

The development by business segment is presented using figures compliant with   
segment reporting. The figures for 2010 and 2009 are comparable.

--------------------------------------------------------------------------------

Revenue in January-September remained at the previous year's level. Changes in  
foreign exchange rates increased the revenue by EUR 74.5 million compared to the
corresponding period last year. During the third quarter, revenue was clearly   
stronger than the previous year. Due to seasonality of the business, the third  
quarter is typically weak in Building and Industrial Services.                  
Operating profit fell short of the year before due to the low level of new      
building system and industrial investments. In addition, the operating profit in
July-September 2010 was weakened by non-recurring expenses amounting to a total 
of approximately EUR 1.9 million associated with the acquisition made in Central
Europe, expenses amounting to approximately EUR 1 million connected with        
post-acquisition personnel reductions in Denmark, and EUR 0.4 million associated
with other acquisitions. The profitability of the acquired businesses is weaker 
than YIT's earlier profitability.                                               
The order backlog at the end of September was 41 percent higher than in pervious
year. As a result of the acquisition made in Central Europe at the end of       
August, the order backlog at the end of September increased by EUR 306 million. 
The order backlog transferred in the acquisition has a lower margin than YIT's  
earlier order backlog.                                                          

Acquisition expands operations in Central Europe                                

YIT aims to offer services related to all building equipment systems close to   
its customers. The goal is to reinforce the local market position through       
acquisitions and organically.                                                   

Sweden accounted for EUR 400.8 million (1-9/2009: EUR 374.6 million) of the     
segment's revenue, Finland for EUR 392.7 million (1-9/2009: EUR 450.1 million), 
Norway for EUR 333.3 million (1-9/2009: EUR 302.1 million), Central Europe for  
295.2 million (1-9/2009: EUR 270.0 million), Denmark for EUR 98.8 million       
(1-9/2009: EUR 108.5 million), the Baltic countries and Russia for EUR 30.4     
million (1-9/2009: EUR 21.8 million) and export countries for EUR 24.0 million  
(1-9/2009: EUR 23.9 million). The changes in the revenue in Sweden and Norway   
are partially due to strengthening exchange rates.                              

An acquisition whereby YIT acquired the shares of a company offering technical  
building system services in Central Europe was completed at the end of August.  
In addition, YIT has implemented several other, smaller business acquisitions in
the Nordic countries during January-September. The revenue obtained through     
business acquisitions in 2010 totals approximately EUR 500 million at an annual 
level    
Service and maintenance accounted for 60 percent of the segment's revenue       

YIT's goal is to be the leading provider of technical system maintenance in the 
Nordic countries and Central Europe. The target is to increase service and      
maintenance operations at a faster rate than other operations. YIT has improved 
the offering of service and maintenance operations by developing a ServiFlex    
concept where customers can agree on extensive service entities in a single     
contract. Service and maintenance operations accounted for 60 percent (1-9/2009:
54%), or EUR 950.5 million (1-9/2009: EUR 833.9 million), of Building and       
Industrial Services January-September revenue. In third quarter the service and 
maintenance revenue amounted to EUR 317.2 million (7-9/2009: EUR 266.0 million) 
accounting for 58 percent (7-9/09: 55%) of the segment's revenue.               

In Norway, ServiFlex agreements were made on the maintenance of more than 20    
properties owned by Vital Eiendom and with the Jakob Hatteland Group Management 
AS at two localities. In addition, YIT agreed on the maintenance of a total of  
450 buildings with four municipalities.                                         

In Sweden, YIT has agreed with three hospitals and several healthcare centres on
the supply, management and maintenance of technical services in Norrbotten      
County. A framework agreement on the installation and renewal of residential    
building systems was made with Vellingebostäder AB. In addition, YIT is in      
charge of maintenance, operation and monitoring services associated with the    
information networks of Mälarenergi Stadsnät.                                   

In Denmark, YIT services the ventilation of a Vattenfall power plant, among     
others. In Finland, YIT is responsible for the building system maintenance of   
five Metsäliitto plants in Äänekoski. In Leuna, Germany, YIT signed an extension
contract on facility management at the TOTAL oil refinery, including both       
building systems and infrastructure.                                            

Industrial Services agreed on the maintenance of the process line and facilities
of Nordkalk AB's limestone plant in Köping, Sweden. After the review period, an 
agreement was made on the expansion of services with Yara to pump and valve     
servicing and maintenance of pipework and steel structures at the Uusikaupunki, 
Harjavalta and Siilinjärvi plants in Finland.                                   

Need for energy-saving services both in buildings and industry                  

YIT aims to be a forerunner in energy-saving services for buildings and         
industry, whose demand is expected to increase in the next few years.           
Energy-saving may be part of both new construction and renovation projects as   
well as maintenance agreements.                                                 

In Germany, a ten-year energy-saving project will be carried out at Germany's   
Foreign Office premises in Berlin. Energy savings will be pursued at ten        
Statkraft power stations in Norway through the renewal of automation systems. In
Finland, an agreement on the total delivery of an energy-saving project was     
signed with the Town of Akaa, where the old heating systems of the school and   
sports centre will be converted to utilise bioenergy. With regard to industrial 
customers, YIT will implement an energy-saving project at Outokumpu's steel mill
in Tornio, replacing the cold rolling mill's existing system of 50 separate     
cooling compressors with a new cooling system based on absorption technology. In
addition, YIT will be in charge of the operation and maintenance of the plant   
for seven years.                                                                

New investments still low                                                       

New investments in building systems have recovered slightly, but still remained 
at a low level. Demand among industrial customers was focused on service and    
maintenance, and the demand for new investments remained at a low level as a    
whole.                                                                          

In Sweden, YIT will deliver, for example, pipework and ventilation and          
adjustment systems to the new court house in Örebro, and in Denmark all         
technical building systems to four court houses in Holstebro, Herning, Kolding  
and Holbæk. In Denmark, the agreement also includes the maintenance of building 
equipment systems for 20 years. In addition, electrical engineering is supplied 
in Denmark to IBM's new data centre and Odense Steel Shipyard vessels, among    
others.                                                                         

In Norway, YIT is responsible for cable, electric and lighting installations in 
a project to renew Oslo's local railway network, and the company will supply    
audiovisual systems to the Ulstein shipping company's office and showroom.      
Electric system deliveries were agreed in Finland during the third quarter at,  
for example, the Tapiola head office in Espoo and Metso's valve plant in        
Helsinki, as was the delivery of all technical building systems at a private    
medical centre in Turku.                                                        

In Germany, YIT will build the local heating network in Bodenmais and supply    
ventilation systems to, for example. the Brandenburg airport in Berlin,         
Byk-Chemie and the new Centre Charlemagne museum in Aachen. In Poland, YIT will 
supply building system services at the Wroclaw main railway station and Lodz    
airport.                                                                        

In Lithuania, YIT will design and install all technical building systems,       
including clean rooms, to the Kaunas University of Medicine pharmacy and the    
plant of Viltechmeda, a company manufacturing medical instruments.              

With regard to industrial customers, in Luleå, Sweden, a significant boiler     
modernisation project was completed during the reporting period whereby a

Revenue increased as production volumes remained at a record-high level in      
residential construction and business premises construction picked up.          
Profitability improved while operations focused on residential development      
projects.                                                                       
The order backlog increased clearly on the previous year as YIT started up new  
residential and business premises projects.                                     
The segment's capital tied into plot reserves totalled EUR 283.5 million        
(9/2009: EUR 340.7 million) at the end of September. The plot reserves included 
1,682,000 (9/2009: 1,748,000) m2 of floor area of residential plots and 969,000 
(9/2009: 904,000) m2 of floor area of plots for business premises.              

Residential sales continued steadily - sufficient sales inventory was maintained
with new start-ups                                                              

YIT's goal is to strengthen its position as the largest housing developer in    
Finland. Residential sales continued to be good for all housing types, including
high-value housing, during the third quarter. YIT sold a total of 1,412         
(1-9/2009: 1,057) residential units directly to consumers in January-September, 
506 of them during the first quarter, 471 during the second quarter and 435     
during the third quarter. Housing prices have increased at a moderate rate.     

The focus of housing construction has been successfully shifted to residential  
development projects aimed directly at consumers in accordance with the market  
demand. YIT has started the construction of a total of 2,003 residential units  
aimed directly at consumers, of which 767 were started during the third quarter.
The number of rental housing project start-ups has decreased compared to the    
year before.                                                                    

The new residential start-ups have maintained the sales inventory at a          
sufficiently high level. At the end of September, YIT had 1,624 (9/2009: 997)   
residential units for sale. The number of completed residential units for sale  
has decreased to a low level, amounting to 116 (9/2009: 266) at the end of      
September. Two-thirds of the residential units under construction have been     
sold.

Business premises market shows signs of picking up     
The construction of business premises picked up as the year advanced. The       
decrease in rent levels has stopped, and investors' yield requirements have     
somewhat decreased.                                                             

New started real estate development projects included the Tiilitie Trade Park in
Petikko, Vantaa, with office, warehouse, production and retail facilities, and  
the construction of Business Park Safiiri in Espoo. In addition, an agreement   
was signed to construct Fingrid's head office in Käpylä, Helsinki. With regard  
to projects started earlier this year, the shopping centre complex connected    
with the Hyvinkää centre quarter project in which the value of YIT's            
construction and building system work is EUR 100 million was under construction.

YIT will construct the new premises of Saunalahti School in Espoo and carry out 
the renovation of the VTT Technical Research Centre of Finland's Fire Safety    
Technology Laboratory. YIT will renovate an office building of 9,200 m2 in      
Pitäjänmäki, Helsinki, for Aberdeen. YIT is implementing a MotorCenter area     
focusing on automotive-related services and equipment in Konala, Helsinki.      

Fewer municipal investments in infrastructure services                          

The demand for infrastructure construction has remained relatively stable, but  
investments by the municipal sector have decreased. This and next year, new     
opportunities will open in the market in the form of, for example, major road   
projects, such as the construction of a second rail track between Kokkola and   
Ylivieska and the construction and renovation of the E18 motorway between       
Koskenkylä and Kotka. YIT is participating in the tenders in cooperation with   
Destia. In the Kokkola-Ylivieska rail track tenders and E18 project, the value  
of the work exceeds EUR 1 billion. In addition, opportunities will open in rock 
engineering, investments by the mining industry and the outsourcing of          
municipalities' technical services.                                             

During the reporting period, YIT entered into contract agreements, for example, 
in earth construction and foundation engineering. In Helsinki's Länsisatama, YIT
is in charge of the construction of the shoreline walls and banks, water supply 
and street bases in the Saukonpaasi planning area. In Lahti, YIT will construct 
the foundations of the Laune parking facility. Regional road maintenance        
contracts were signed in Lieto, Alavus and Oulu, for example, in July-September.
During January-September, YIT had large-scale road projects underway in         
infrastructure services, such as the major project related to the improvement of
the Kehä I ring road, a project involving bridge and road work in Savonlinna,   
and a tunnel for the Kehärata (Ring line) project in Vantaa.

Revenue increased on the previous year as a result of progress of residential   
construction and the picking up of residential sales.                           
Operating profit improved through favourable development of residential sales   
and YIT's higher selling prices compared to last year.                          
The order backlog increased slightly from the end of June, at which time it     
stood at EUR 946.8 million. The weakening of the ruble had an effect of EUR     
-69.9 million in the segment's order backlog in July-September. The order       
backlog includes residential units whose construction was suspended in Russia in
October 2008 due to market uncertainties. At the end of September 2010, the     
value of projects that were still suspended amounted to EUR 161.3 million       
(9/2009: EUR 308.1 million).                                                    
The segment's capital tied into plot reserves totalled EUR 282.8 million        
(9/2009: EUR 244.7 million) at the end of September. The plot reserves included 
2,394,000 (9/2009: 2,295,000) m2 of floor area of residential plots and 699,000 
(9/2009: 701,000) m2 of floor area of plots for business premises in Russia, the
Baltic countries and the Czech Republic.                                        
YIT's target is to start the construction of approximately 1,000 residential    
units in October-December 2010 in International Construction Services covering  
Russia, Baltic countries and Czech Republic and Slovakia.                       

Russian residential sales remained favourable - a considerable number of units  
will be completed during the fourth quarter                                     

YIT aims to increase housing production in Russia according to market demand in 
the current cities and improve its reputation as a reliable housing construction
company. Russia generated 90 percent (1-9/2009: 83%) of the segment's revenue   
for January-September. Revenue increased by 46 percent in Russia compared with  
the previous year, amounting to EUR 297.1 million (1-9/2009: EUR 203.4 million).
Capital tied into plot reserves in Russia totalled EUR 208.4 million (9/2009:   
EUR 166.9 million) at the end of September. The plot reserves included 2,025,000
(9/2009: 1,950,000) m2 of floor area of residential plots and 563,000 (9/2009:  
565,000) m2 of floor area of plots for business premises.                       
In Russia, the focus of operations is on residential development projects. The  
majority of housing start-ups have taken place in St. Petersburg and the Moscow 
Oblast. Of business premises projects, production facilities for Dermosil in    
Gorelovo, near St. Petersburg, are underway. The extension work for Atria's     
factory was completed during the period.                                        

Residential sales volume for January-September increased on the year before. In 
January-September, YIT sold 2,216 (1-9/2009: 1,646) residential units in Russia.
The number of residential units sold during the first quarter was 817 units,    
during the second quarter 682 units and during the third quarter 717 units.     

Residential sales have been supported by YIT's own marketing and promotion      
activities and housing loan collaboration with banks. Loan financing was        
utilised in 22 percent of YIT's residential sales in 2010. The significance of  
loan financing has increased during the course of the year, and in the third    
quarter, the customer has taken out a home loan in 29 percent of YIT's          
residential sales. Residential demand is supported by the gradual improvement of
the economy, consumer confidence and increased availability of loans to         
customers. In October YIT has increased the residential selling prices in some  
projects following the steadier development of prices during the summer. The    
price development of residential units on the market is uneven and the average  
selling prices have declined in some cities. Typically the selling prices of    
apartments are lower in projects that are in their early stage of construction. 

YIT has started new residential projects in Russia in response to demand since  
the second half of 2009. The number of residential units for sale has remained  
steady, amounting to 3,931 at the end of September. The number of completed     
residential units for sale decreased to 602 at the end of September.            

The number of residential units under construction has increased as residential 
projects have not been completed in Russia, significantly more residential units
will be completed during October-December than in January-September when the    
corresponding figure was 940 (1-9/2009: 2,461). Completion of the projects      
requires commissioning by the authorities.

1) Completion of the projects requires commissioning by the authorities.        
2) At the end of September 2010, YIT had 928 (9/2009: 2,485) residential units  
at Russian sites whose construction was suspended in the autumn of 2008. These  
residential units are not included in the figure for residential units under    
construction shown in the table. Changes in the number of residential units may 
take place after the start of construction due to the division or combination of
residences.                                                                     

Housing start-ups were continued in Central Eastern Europe                      

YIT's aim is to increase its residential production in the Central Eastern      
European countries. Lithuania, Estonia, Latvia and the Czech Republic accounted 
for 10 percent (1-9/2009: 16%) of the segment's revenue for January-September.  
The revenue of these countries decreased by 21 percent compared with the        
previous year, amounting to EUR 33.8 million (1-9/2009: EUR 43.0 million).      
Capital tied into plot reserves in the Baltic countries and the Czech Republic  
totalled EUR 74.5 million (9/2009: EUR 77.9 million) at the end of September.   
The plot reserves included 351,000 (9/2009: 345,000) m2 of floor area of        
residential plots and 136,000 (9/2009: 136,000) m2 of floor area of plots for   
business premises.                                                              

During the first quarter of 2010, YIT started its first new residential         
construction projects for more than two years in the Baltic countries. In the   
third quarter, YIT started the construction of its first housing project in the 
Czech Republic, to which country the Group expanded its operations through an   
acquisition in 2008.                                                            

In total, the construction of 329 (1-9/2009: 0) residential units was started in
the Baltic countries and the Czech Republic, of which 111 were in the first     
quarter, 122 in the second quarter and 96 in the third quarter. At the end of   
September, there were 329 (9/2009: 0) residential units under construction.     

YIT's number of apartments for sale is still low in the Baltic countries and the
Czech Republic. A total of 33                                                   
(1-9/2009: 250) residential units were sold in                                  
these countries in January-September. There were 336 (9/2009: 46) residential   
units for sale at the end of September, 24 (9/2009: 46) of them completed. The  
number of residential units completed during the period was 0 (1-9/2009: 592).  

The Group's operations were expanded to Slovakia in October when YIT acquired 70
percent of Reding a.s., a construction company specialising in residential and  
business premises construction.                                                 

PERSONNEL                                                                       

In January-September 2010, the Group employed 23,796 (1-9/2009: 24,787) people  
on average. At the end of the period, the Group employed 25,943 (9/2009: 24,003)
people, whereas at the end of June the figure was 23,877. In connection with the
acquisition completed in Central Europe, approximately 2,000 employees were     
transferred to YIT's Building and Industrial Services segment at the beginning  
of September. YIT employed approximately 1,000 summer employees during the      
summer of 2010.                                                                 

During the first half of the year, it was decided to adopt a new share-based    
incentive scheme, aimed at supporting the company's strategy of profitable      
growth and supplementing the already available incentive schemes. The incentive 
scheme covers about 250 people in 2010, and its cost effect was about EUR 2.5   
million in January-September.                                                   

Personnel by business segment                                                   

The largest segment by personnel was Building and Industrial Services, employing
76 percent (9/2009: 75%) of YIT's personnel. Construction Services Finland      
employed 12 percent (9/2009: 12%), International Construction Services 10       
percent (9/2009: 12%) and Corporate Services 1 percent (9/2009: 1%) of the      
personnel.

the Board of Directors. The share issue authorisation also includes an          
authorisation to decide on the conveyance of treasury shares.                   

YIT Corporation held 2,145,000 treasury shares at the beginning of the review   
period, purchased on the basis of the authorisation given by the General Meeting
of October 6, 2008. The number of shares held by the company did not change     
during the review period. During the period, no shares in the parent company    
were owned by subsidiaries.                                                     

There were no share issues during the period and the company did not float      
convertible bonds or bonds with warrants. At the end of the period, the parent  
company's Board of Directors did not have authorisations to issue convertible   
bonds or bonds with warrants.                                                   

Trading in shares and share options                                             

At the beginning of the year, YIT's share price was EUR 14.45, and the closing

Number of shareholders                                                          

At the beginning of the year, the number of registered shareholders was 29,678  
(2009: 25,515) and 32,751 (9/2009: 30,127) at the end of the period. The number 
of private investors increased by approximately 2,700 during January-September. 
At the beginning of the year, a total of 38.7 percent (2009: 36.5%) of the

YIT Corporation's shares.                         

ESTIMATE OF FUTURE TRENDS                                                       

Market situation                                                                

In the Building and Industrial Services segment, the growth in the demand for   
building system service and maintenance operations will continue hand in hand   
with an increase in the level of technical equipment in buildings. The          
efficiency enhancement measures of companies and government open up             
opportunities for the outsourcing of real estate services. The demand for       
energy-efficiency services will increase in the next few years in the Nordic    
countries, Germany and Austria, in particular, with public sector stimulus      
measures and renewed environmental legislation. New investments in office       
premises will remain low, but the construction of retail premises will continue 
at a moderate level, and, additionally, public sector investments will be       
realised. The demand for renovation and reconstruction projects will continue to
grow. Industrial investments are at a low level in Finland, but the demand for  
industrial maintenance services will remain relatively stable.                  

With regard to Construction Services Finland, housing demand is expected to     
continue to be good. The demand for owner-occupied housing continues to be      
supported by low interest rates, favourable employment rates and increased      
consumer confidence. The need for new housing is also maintained by the smaller 
size of household-dwelling units, migration and population growth. The increase 
in residential prices has continued to be moderate. The business premises market
shows signs of picking up. The decrease in rents has stopped, and investors'    
yield requirements have decreased. The need for renovation will rise steadily.  
In the Finnish infrastructure market, new traffic-related projects will begin in
this and the next year. Opportunities will also open in connection with road and
regional maintenance contracts. The demand for municipal infrastructure projects
decreases, and there is uncertainty related to decision making regarding project
start-ups.                                                                      

With regard to International Construction Services, the slight increase in      
housing demand in Russia is expected to continue. There is still a great need   
for housing in Russia, and the demand outlook for residential units aimed at    
YIT's customer segment is good in the long term. Russia's economic situation and
consumer behaviour are strongly influenced by oil prices and the development of 
the ruble exchange rate. In addition, the development of the housing loan       
market, interest rates, employment rates and spending power and expectations of 
inflation will have an impact on residential sales. In October YIT has increased
the residential selling prices in some projects following the steadier          
development of prices during the summer, but price development of residential   
units on the market is uneven. Construction of offices is low in Russia, but the
demand for industrial and retail premises is increasing. There is a need for    
more room and improving the quality of housing in the long term in the Baltic   
countries and Central Eastern Europe.                                           

Strategic targets                                                               

YIT Corporation's Board of Directors confirmed the Group's strategy for         
2011-2013 on August 18, 2010. The key strategic target is profitable growth. The
Group's annual revenue growth target has been increased to more than 10 percent 
on average. The target was an average annual revenue growth of 5-10 percent. The
Group's other strategic target levels remain unchanged: return on investment of 
20 percent, operating cash flow after investments must be sufficient for        
dividend payout and reduction of debt, equity ratio of 35 percent and dividend  
payout of 40-60 percent of net profit for the period.                           

In terms of business operations, the focus areas of YIT's growth are building   
system service and maintenance operations and residential construction. YIT     
seeks growth by strengthening its local market position and through geographical
expansion to new countries. Building system services are increased in the Nordic
countries and Central Europe and residential construction in Finland, Russia,   
the Baltic countries and Central Eastern Europe. The Group's potential new      
market areas are the United Kingdom, the Netherlands and Belgium in building    
system services and Poland in construction services. Growth is sought both      
through acquisitions and organically.                                           

YIT published a stock exchange release on the confirmation of the strategy on   
August 19, 2010, and materials for the Capital Market Day focusing on the       
strategic focus areas on September 2, 2010.                                     

Most significant business risks and uncertainties                               

YIT has specified the major risk factors and their management from the point of 
view of the Group as a whole, taking the special characteristics of YIT's       
business operations and environment into consideration. Risks are divided into  
strategic, operational, financial and event risks. A more detailed account of   
YIT's risk management policy and the most significant risks has been published  
in the Annual Report 2009. Financing risks are described in more detail in the  
notes to the financial statements for 2009.                                     

The most significant operational short-term business risks and uncertainties are
connected with the development of business system and industrial projects,      
success in the integration of the acquired companies and the continuity of the  
favourable development of residential sales and the sales and price risk of the 
order backlog mainly due to unsold residential units. In Building and Industrial
Services the order backlog has grown due to an acquisition completed in August  
in Central Europe and the integration of companies and the development of       
operations have started in line with the plans. YIT manages sales risk by       
matching the number of housing start-ups with the estimated residential demand  
and the number of unsold residential units. The housing production figures are  
presented under Development by business segment.                                

There is a currency risk related to investments in ruble terms. Capital invested
in Russia totalled EUR 509.7 million (9/2009: EUR 563.5 million) at the end of  
the period. The amount of net equity investments at the end of the period was   
EUR 329.5 million (9/2009: EUR 235.4 million). The net investments in the       
Russian subsidiaries are unhedged in accordance with the finance policy, and a  
potential devaluation of the ruble would have a negative impact equal to the    
amount of equity on the Group's shareholders' equity. Debt investments amounted 
to EUR 180.1 million (9/2009: EUR 328.1 million) at the end of the period, and  
this exposure was hedged in full. The difference in the interest rates between  
the euro and ruble have an effect on hedging costs and therefore net financial  
expenses.                                                                       

YIT tests the value of its plots as required by the IFRS accounting principles. 
Plot reserves are measured at acquisition cost and the value is impaired when it
is estimated that the building being constructed on the plot will be sold at a  
price lower than the sum of the price of the plot and the construction costs.   

OUTLOOK FOR 2010                                                                

YIT Corporation estimates that the Group's (IFRIC 15) revenue will increase and 
profit before taxes will increase significantly in 2010 compared with 2009. YIT 
estimates that the Group's fourth quarter revenue and profit before taxes will  
be the strongest of the year. (The outlook for the fourth quarter has been      
specified.)                                                                     

The Group's revenue and profit will clearly focus on the fourth quarter, because
in accordance with the new accounting policy adopted at the beginning of 2010,  
residential development projects are only recognised in Group-level figures when
the project has been completed. Both in Finland and in Russia, the number of    
completed units in residential development in January-September 2010 was        
considerably lower than in the previous year - in Finland 559 (1-9/2009: 1,029) 
and in Russia 940 (1-9/2009: 2,461). Especially in Russia, significantly more   
residential units will be completed during October-December than in             
January-September 2010. Completion of the projects requires commissioning by the
authorities.                                                                    

The demand for housing is expected to remain at a favourable level in 2010 in   
Finland as well as Russia.                                                      

In Finland, residential demand continues to be supported by low interest rates, 
favourable employment rates, increased consumer confidence and structural       
factors, such as migration, population growth and decreasing family sizes. The  
increase in residential prices has continued to be moderate. YIT had 4,543      
(9/2009: 2,946) residential units under construction at the end of September    
2010, of which two thirds were sold. There were 1,624 (9/2009: 997) residential 
units for sale, of which completed units numbered 116 (9/2009: 266).            

There is a great need for new housing in Russia, and therefore the demand       
outlook for residential units aimed at YIT's customer segment is good in the    
long term. In October YIT has increased the residential selling prices in some  
projects following the steadier development of prices during the summer.        
Residential demand is supported by increased consumer confidence and increased  
availability of financing for housing. YIT had 5,797 (9/2009: 6,080) residential
units under construction at the end of September 2010. There were 3,931 (9/2009:
4,014) residential units for sale, of which completed units numbered 602        
(9/2009: 466).                                                                  

YIT's target is to start the construction of approximately 1,000 residential    
units in October-December 2010 in International Construction Services covering  
Russia, Baltic countries and Czech Republic and Slovakia.                       

The opportunities for organic growth in Building and Industrial Services are    
supported by the need for service and maintenance as well as renovation and     
public sector projects. There are many small companies operating in the         
technical building system market, and the consolidation of the market will      
provide opportunities for acquisitions. New investments in technical building   
systems will remain low in all YIT markets, particularly due to the low volumes 
of business premises construction. Industrial investments are also at a low     
level in Finland, but the demand for industrial maintenance services will remain
relatively stable. YIT has an extensive network of local offices in the markets 
where it operates and a solid market position in building system and industrial 
service and maintenance operations, projects and energy-efficiency services.    

In the Finnish infrastructure market, new traffic-related projects will begin in
this and the next year at the same time with decreasing demand in the municipal 
sector. Opportunities will also open in connection with road and regional       
maintenance contracts. YIT has large-scale road projects underway in            
infrastructure services. The Group has special expertise in infrastructure and a
solid position as the largest private provider of road maintenance services in  
Finland.

In the International Construction Services segment, YIT entered into an         
agreement on acquiring the Slovakian construction company Reding a.s. on August 
12, 2010. Reding is a construction company focusing on residential and business 
premises construction. The company has 150 employees. The transaction was       
completed on October 7, 2010, after the Slovakian competition authorities had   
approved the share transaction and the other terms and conditions of the        
agreement had been fulfilled. YIT acquired a 70 percent holding in the company. 
YIT has additionally agreed to purchase the remaining 30 percent from the seller
gradually by 2016. The seller will continue as the company's Managing Director.

As from the beginning of 2010, Group reporting will apply the new IFRIC 15      
interpretation, according to which own residential development projects will be 
recognised at the time of delivery and own commercial real estate development   
projects based on the percentage of completion or at the time of delivery. The  
figures for 2010 and 2009 are comparable.

SEGMENT INFORMATION BY QUARTER                                                  

YIT applies the IFRIC 15 Agreements for the Construction of Real Estate IFRS    
interpretation from the start of the financial period begun on January 1, 2010. 
Due to the application of the interpretation, Group reporting and segment       
reporting differ.                                                               

In segment reporting, the figures will continue to be calculated based on the   
previous accounting principle, i.e. percentage of completion will be applied in 
the recognition of revenue from own residential and commercial real estate      
development projects.                                                           

As from the beginning of 2010, Group reporting applies the new interpretation.  
According to the interpretation own residential development projects will be    
recognised at the time of delivery. Own commercial real estate development      
projects will be recognized based on the percentage of completion or            
alternatively at the time of delivery.                                          

Figures for 2010 and 2009 are comparable.

1) The operating profit of Building and Industrial Services in 7-9/2010 was     
weakened by non-recurring expenses amounting to a total of approximately EUR 1.9
million associated with the acquisition made in Central Europe, expenses        
amounting to approximately EUR 1 million connected with post-acquisition        
personnel reductions in Denmark, and EUR 0.4 million associated with other      
acquisitions.                                                                   

On September 30, 2009, the court of arbitration issued its ruling in the dispute
concerning the mechanical installation contract YIT carried out for Neste Oil's 
Porvoo oil refinery. The effect of the ruling on Building and Industrial        
Services' operating profit for Q3/2009 was EUR -3.2 million.

1) YIT has suspended the construction of certain residential projects in the    
start-up phase in Russia. The sales of these projects had not yet begun. These  
projects have 928 (9/2009: 2,485) residential units and they accounted for EUR  
161.3 million (9/2009: EUR 308.1 million) in the order backlog at the end of    
September 2010.                                                                 

2. CONSOLIDATED FINANCIAL STATEMENTS JAN 1 - SEP 30, 2010                       

As from the beginning of 2010, Group reporting will apply the new IFRIC 15      
interpretation, according to which own residential development projects will be 
recognised at the time of delivery and own commercial real estate development   
projects based on the percentage of completion or at the time of delivery. The  
figures for 2010 and 2009 are comparable.

1) The operating profit of Building and Industrial Services in 7-9/2010 was     
weakened by non-recurring expenses amounting to a total of approximately EUR 1.9
million associated with the acquisition made in Central Europe, expenses        
amounting to approximately EUR 1 million connected with post-acquisition        
personnel reductions in Denmark, and EUR 0.4 million associated with other      
acquisitions.                                                                   

The operating profit 7-9/2009 includes EUR -3.2 million due to the ruling issued
by the court of arbitration on September 30, 2009 concerning the mechanical     
installation contract YIT carried out for Neste Oil's Porvoo oil refinery.

3. NOTES   

ACCOUNTING PRINCIPLES OF THE INTERIM REPORT                                     

YIT Corporation's Interim Report for January 1 - September 30, 2010 has been    
drawn up in line with IAS 34: Interim Financial Reporting. The information      
presented in the Interim Report has not been audited. YIT has applied the same  
accounting policy and IFRS standards and interpretations in the drafting of the 
Interim Report as in its annual financial statements for 2009. However, the     
following new standards, interpretations and amendments on current standards    
that have been approved by EU have been applied as of January 1, 2010.          

IFRIC 15 Agreements for the Construction of Real Estate                         

YIT applies 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 IFRIC 15 interpretation contains guidelines on when the revenue       
generated by the construction of real estate must be recognised on the basis of 
the delivery 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 own development projects involving residential and commercial real estate.   
The interpretation will not have any impact on construction contracting or      
building and industrial services.                                               

In Group-level reports as of January 1, 2010, the revenue generated by YIT's own
residential development projects are recognised 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 construction work
started using the percentage of completion method.                              
YIT had sold its commercial real estate development projects that were under    
construction 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 could be recognised in accordance with 
the old practice also in the future. The share of income and expenses to be     
recognized would then 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 construction work started. In the 
case of YIT's new 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. These projects will be recognised when   
the construction work has started or when the project is complete.              

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.      

Due to applying the interpretation the items in consolidated income statement,  
consolidated balance sheet and consolidated cash flow statement for the previous
periods have been adjusted for comparability as follows:

Under the new practice, the quarterly revenue and profits of the YIT Group will 
now fluctuate more in accordance with the completion dates of development       
projects. 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.
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 prior accounting principles.                

YIT published the comparison figures for consolidated income statement,         
consolidated balance sheet, consolidated cash flow statement and key figures for
2009 in a stock exchange release published on March 23, 2010.                   

Other standards and interpretations                                             

Other standards and interpretations that have been applied as of January 1, 2010
have minor or no effects on YIT during the report period, and they include:

The Group's strategic financial targets guide the use and management of the     
Group's capital. Achieving the strategic targets is supported by maintaining an 
optimum Group capital structure. Capital structure is mainly influenced by      
controlling the investments and the amount of working capital tied to business  
operations.                                                                     

A more detailed account of financial risks has been published in the notes to   
the financial statements for 2009.                                              

SEGMENT INFORMATION                                                             

YIT applies the IFRIC 15 Agreements for the Construction of Real Estate IFRS    
interpretation from the start of the financial period begun on January 1, 2010. 
Due to the application of the interpretation, Group reporting and segment       
reporting differ.                                                               

In segment reporting, the figures will continue to be calculated based on the   
previous accounting principle, i.e. percentage of completion will be applied in 
the recognition of revenue from own residential and commercial real estate      
development projects.                                                           

As from the beginning of 2010, Group reporting will apply the new               
interpretation. According to the interpretation own residential development     
projects will be recognised at the time of delivery. Own commercial real estate 
development projects will be recognized in most cases based on the percentage of
completion or alternatively at the time of delivery.                            

The figures for 2010 and 2009 are comparable.                                   

The chief operating decision-maker has been identified as the YIT Group's       
Management Board, which review the Group's internal reporting in order to assess
performance and allocate resources to the segments.

BUSINESS COMBINATIONS AND DISPOSALS (EUR million)                               

In the Building and Industrial Services segment, YIT agreed on June 23, 2010,   
that it will acquire the entire share capital of Caverion GmbH, the parent      
company of the German Caverion group of companies, providing technical building 
system services. Caverion Group's most significant countries of operation are   
Germany, Poland and Hungary. The completion of the transaction was subject to   
approval by the competition authorities. The companies in Caverion Group will be
consolidated into YIT Group from September 1, 2010.                             

The final purchase price of the Caverion GmbH shares was EUR 73.0 million, and  
it has been paid in cash.                                                       
The fair value of the acquired identifiable intangible assets is, according to  
preliminary calculations, approximately EUR 4.4 million, and the net fair value 
of the assets held for sale is approximately EUR 2.6 million. The acquisition   
will preliminary generate approximately EUR 60.0 million of goodwill. According 
to the management's estimate, the goodwill is based on the operational network  
provided by the Caverion Group companies, competence of the personnel and market
share in the Central European market as well as shifting the focus of business  
operations in the acquired units towards long-term service agreements and       
servicing and maintenance operations. Significant synergy benefits are seen in  
operational models that will be harmonised, the expanding service offering and  
procurement.

Moreover, YIT implemented other small business acquisitions in the Building and 
Industrial Services segment during the review period. The companies acquired    
were Eltjänst Br Björk Installation AB, Ekonomisk Luftbehandling AB, Fristads   
Rör-El AB, G:sson Teleteknik AB and Ferm VVS in Sweden, Ugelvik Nesset AB, Haug 
og Ruud AS and Energiprosjekt in Norway and Brdr. Petersens Eftf. A/S and Carl  
Christensen & Co. A/S in Denmark.                                               

The total cost of the smaller acquisitions amounts to EUR 7.8 million. The      
acquisitions do not result in goodwill. EUR 9.4 million of the purchase price   
has been allocated to intangible rights or assets in connection with the        
customer base, agreement base, compensation for prohibition of competition or   
unpatented technology.

EVENTS AFTER THE REVIEW PERIOD                                                  

In the International Construction Services segment, YIT entered into an         
agreement on acquiring the Slovakian construction company Reding a.s. on August 
12, 2010. Reding is a construction company focusing on residential and business 
premises construction. The company has 150 employees. The transaction was       
completed on October 7, 2010, after the Slovakian competition authorities had   
approved the share transaction and the other terms and conditions of the        
agreement had been fulfilled. YIT acquired a 70 percent holding in the company. 
YIT has additionally agreed to purchase the remaining 30 percent from the seller
gradually by 2016. The seller will continue as the company's Managing Director. 

Reding a.s. is consolidated into YIT Group from October 7, 2010, with a 100     
percent share. According to preliminary calculations, the purchase price is     
approximately EUR 14.5 million and the fair value of the acquired net assets is 
approximately EUR 9.7 million. The remaining purchase price will be allocated to
intangible assets and rights, and the transaction is not expected to result in  
goodwill.
