Consolidated Financial Statements of the Implenia Group Change in Treasury Shares

General Presentation of the consolidated financial statements The consolidated financial statements of the Implenia Group are prepared as being those of the former Zschokke Group which, in compliance with IFRS standards, acquired Batigroup. For more information on the acquisition, please refer to note 1 Consolidation scope. The consolidated financial statements of the Implenia Group are prepared in accordance with IFRS (International Financial Reporting Standards) as defined by the International Accounting Standard Board (IASB). Changes in accounting principles The following new standards, amendments to standards and IFRS interpretations have been considered for the preparation of the 2006 Financial Report: – Amendments to IAS 19 – Employee benefits: actuarial gains and losses, group plans and disclosures – Amendment to IAS 39 – Option to designate a financial instrument at fair value – Amendment to IAS 39 – Cash flow hedge accounting of forecasted intragroup transactions – Amendment to IAS 39 and IFRS 4 – Financial guarantee contracts – Amendment to IAS 21 – Net investments in foreign operations – IFRS 6 – Exploration for and evaluation of mineral assets – IFRIC 4 Interpretation – Determining whether an arrangement contains a lease agreement – IFRIC 5 Interpretation – Rights to interests arising from decommissioning, restoration and environmental rehabilitation funds. – IFRIC 6 Interpretation – Liabilities arising from participating in a specific market, waste electrical and electronic equipment. The impact is not significant for the consolidated accounts and/or is limited to additional disclosure. The content of other accounting principles has not been changed. However, the form of some principles has been adapted and, if appropriate, additional disclosure has been added to facilitate understanding.

Accounting Principles

Standards, interpretations and amendments to published (but not yet mandatory) standards: The following standards, amendments and interpretations have already been adopted by IASB, although their application will become mandatory only for the years starting after 1 January 2006. (Implenia decided not to early adopt those requirements). – IFRS 7 Financial instruments: Disclosures (for years starting from 1 January 2007). The new disclosure requirements have been considerably extended. They include, among other things, disclosures on financial instruments that may have an impact on the financial situation and results of the enterprise, as well as on the objectives, principles and processes of risk management in relation to financial instruments. Quantified disclosures on the risks to which the enterprise is exposed are provided on the basis of the information used by the operating management. The application of IFRS7 will have no impact on the consolidated result. – IFRS 8 Operating Segments: (for years starting from 1 January 2009). IFRS 8 replaces IAS 14 Segment Reporting. The definitions of operating segments and the reporting are based on the information used by the operating management. The application of IFRS 8 will influence the reporting by segments, but will have no impact on the consolidated result. – IFRIC 7, Applying the Restatement Approach under IAS 29 standard – Financial Reporting in Hyperinflationary Economies. (for years starting from 1 March 2006). – IFRIC 8, Scope of IFRS 2 (for years starting from 1 May 2006). – IFRIC 9, Reassessment of Embedded Derivatives (for years starting from 1 June 2006). – IFRIC 10, Interim Financial Reporting and Impairment (for years starting from 1 November 2006). – IFRIC 11, Group and Treasury Share Transactions according to IFRS 2 (for years starting from 1 March 2007). – IFRIC 12, Service Concession Arrangements (for years starting from 1 January 2008). The management has examined these new standards and interpretations and has reached the conclusion that they will have no significant impact on the presentation of the accounts of Implenia.

Consolidated Financial Statements of the Implenia Group Notes to the Consolidated Financial Statements 11

Transactions with minority interest holders Transactions with minority interest holders are treated similarly to transactions with third parties. Sales of minority shares generate a profit or a loss in the consolidated accounts. Purchases of minority shares generate goodwill amounting to the difference between the purchase price and the corresponding net assets value of the affiliated company. Basis of consolidation The parent company of the group (Holding) is Implenia Ltd, with registered office in Dietlikon, Switzerland. The consolidated accounts are presented in thousands of Swiss francs, unless indicated otherwise. In principle, it owns directly the main subsidiaries of the Group that come within the consolidation. The details of the shareholdings held directly or indirectly by Implenia Ltd are given on pages 44 and 45 of the present annex. Valuation is based on historical cost, with the exception of certain items for which the valuation methods are described below. Subsidiaries Subsidiaries are companies in which Implenia exercises control over the financial and commercial policies. This is generally the case if Implenia holds, directly or indirectly, more than 50% of the capital or the majority of the voting rights. To determine whether control exists, the existence and impact of potential existing or convertible voting rights is considered. The accounts of these companies are prepared using consistent accounting policies as those of the group and in conformity with IFRS. The reporting year of subsidiaries is similar to the one of the parent company. All assets and liabilities as well as expenses and revenues are fully consolidated. All intra-group balances, transactions, income and expenses and profits and losses resulting from intragroup transactions that are recognised in assets and that have not yet been realised in relation to third parties (for example: inventory movements), are eliminated in full. Intra-group transactions are done at market prices. New subsidiaries are consolidated from the date of their acquisition, which corresponds to the date of taking control, using the Purchase Method of accounting, as defined by the standard IFRS 3. A company is excluded from the consolidation on the date when control ceases.

Associated Companies Associated companies are companies in which Implenia exercises a considerable influence, but not control. In principle, they are companies in which the Group holds between 20 and 50% of the capital. These entities are accounted for using the Equity Method. In the balance sheet, they are separately disclosed. The reference date for the Equity Method calculation is, in principle, the same as the year end date of the parent company. However, if some of the accounts are not available at this time, the valuation is performed on the basis of the last available financial statements, taking into consideration any changes noted since then. Associated companies are included in the consolidation using accounting and valuation principles similar to those of the group. The share of the Group in the result of associated companies is accounted for separately in the consolidated income statement. The share in losses is limited to the value of the shareholding, in so far as the Group is not committed to any liability beyond that value. Work partnerships (consortia) These are activities carried on jointly by two or more partners and are performed, in general, in the legal form of a partnership. The partners share control and share the running, resources and know-how with the aim of performing a given activity in the context of one or more contracts. The partners must make available human and material resources that are invoiced directly to the work partnership. The results achieved for works executed jointly are distributed on the basis of contractual agreements and are recorded in the context of these activities. Certain work partnerships have their own assets, acquired or contributed for the execution of the planned activity. The share of the Group in these net assets is presented as credits and debits in relation to the work partnership. The composition of the net assets of the work partnerships is presented in the notes.

Minority holdings The minority holdings in which Implenia does not exercise predominant control, in general shareholdings not exceeding 20%, are classified as “available for sale” and are reported in the balance sheet at their fair value, in accordance with IAS 39. Changes in the fair value are recorded in equity. These unrealised profits and losses reorded in equity are transferred to the income statement on sale of the shareholdings. The losses previously recorded in equity are also transferred to the income statement whenever a significant and lasting impairment in the value of the shareholdings is noted. Estimates and assumptions The preparation of the Group financial statements according to IFRS standards requires that a number of assumptions be formulated concerning the future, which entails a certain number of judgements and estimates that directly impact the values disclosed in the balance sheet and the income statement. These assumptions, judgements and estimates are based on experience and on factors considered relevant in the given conditions. Assumptions are subject to permanent review. Changes made in the estimates used are accounted for directly in the year when the estimate was reviewed. The categories that are especially based on assumptions and estimates and for which such estimates may generate significant adjustments to the book values during the following year are detailed below. Turnover, Works in progress and Work partnerships: the valuation of works in progress and work partnerships, and therefore also the determination of their turnover, which is done according to the “Percentageof-Completion” (PoC) Method, is based on estimates and assumptions on the income, costs and final margins of the projects in progress, as well as the income, costs and margins already realised on the balance sheet date. Goodwill: this asset is subject to an annual impairment test. Such a test requires the estimation of future cash flows, as well as the discount rate. Tangible fixed assets: depreciation is based on estimates of the useful life of the tangible fixed assets. Deferred tax assets: the valuation is based on estimates of future profits.

Judgements in the application of accounting and valuation methods Some judgements are required notably in the following cases: – Securities can be classified in various categories – In the context of the valuation of provisions for benefit plan commitments, actuarial gains and losses can be accounted for differently. – Assets that the Group considers selling must be examined to ascertain whether realisation is possible and highly probable. If these conditions are met, these assets must be reported as “held for sale” and valued accordingly. The decisions taken by Implenia in the cases that actually arose are disclosed in the comments on the accounting and valuation principles. Foreign currency translation The consolidated financial statements are presented in Swiss francs, the local and operating currency of Implenia Ltd and of most of the affiliated companies. Transactions and balances in foreign currencies Transactions in foreign currencies are converted into the operating currency at the exchange rate prevailing on the day of the transaction. Financial assets and liabilities in foreign currencies are converted at the exchange rate prevailing on the balance sheet date. The exchange rate differences resulting from the settlement of such transactions and from the translation of balance sheet items are recognised in the income statement.

Consolidated Financial Statements of the Implenia Group Notes to the Consolidated Financial Statements 13

Translation of the accounts of subsidiaries whose accounting records are maintained in foreign currencies The assets and liabilities of balance sheets prepared in foreign currencies are converted at the rate prevailing on the balance sheet date of the parent company. The income statement is translated at the average exchange rate. The resulting exchange rate differences on the balance sheet and income statement items are posted directly to equity. The exchange rate differences related to the conversion of group loans, being in the nature of a shareholding, are also posted directly to equity. On the sale of these shareholdings, the exchange rate differences that were posted to equity are transferred to the income statement. Reporting by segments The operational organisation of the Group is based on the following main segments of activities: General contracting The activities carried on by this division include general project planning, work as general contractor and total contractor in the construction sector. Construction Works The Construction works division includes both the Industrial Works and the Infrastructure Works units. These works include road construction, special construction works, civil engineering infrastructures, tunnels, and building construction and renovation. Services Services are provided by the Groupâ&#x20AC;&#x2122;s Real Estate division. They include studies, management and running of buildings, coordination, engineering, and project planning, as well as Facility Management. Real estate Real estate activities are integrated into the Groupâ&#x20AC;&#x2122;s Real Estate division. They include real estate promotion activities and the implementation of projects in the real estate field.

Head office overheads and sundry expenses This category includes the costs of the parent company that cannot be assigned to a segment and the inactive affiliated companies. At the segment reporting level, this category includes the Groupâ&#x20AC;&#x2122;s financial commitments (consortium loan) in particular. The list of affiliated companies on pages 44 and 45 shows how each company is assigned to the various segments. Because the Implenia group presently operates essentially in Switzerland, no secondary geographical segment was presented. Consolidated income statement Turnover Turnover contains all the income from the different activities of the group. Within General Enterprise and Construction divisions orders are recorded according to the Percentage of Completion Method. The income and results are recognised as a proportion of the work done in relation to the total contract value. Expected losses on the order book are included in relation to the valuation of works in progress and are recognised as a reduction in turnover. Conversely, price uplifts, supplements and bonuses are included if they have already been accepted by the customer. For work partnerships only the work done for the work partnerships and the share in the results of these work partnerships are included in the turnover. The turnover of Services is calculated on the basis of the service actually performed for the customer on the balance sheet date. For the Real estate segment, the turnover includes the result on sale of real estate operations and the income from temporary leases (pending sale). The sales are recognised when the risk is actually transferred, which, generally speaking, is at the time when ownership is transferred, with registration in the Land Register. Reductions of income such as losses on debtors, changes in provisions for unsecured debts, rebates or discounts directly related to the invoiced services are accounted for as a reduction of turnover.

Materials and subcontractors Materials and subcontractors include all items of cost that are directly allocated to projects and are taken into account in the calculation of the project margin. Personnel Personnel costs consists of gross salaries, social security contributions charged to the employer, as well as any other employee benefits that must be accounted for in the period concerned. Other operating expenses These are the other operating expenses that are not directly allocated to projects. Financial charges and income Financial expenses consist of the interest charged on financial commitments, foreign currency exchange losses, losses on financial instruments and losses on the revaluation or sale of financial investments. Borrowing costs directly related to a real estate operation are accounted for as part of the cost of the operation. Financial income consists of the interest income on loans granted, dividends, foreign currency exchange gains, gains on financial instruments and profits on the revaluation or sale of financial investments. Income taxes Taxes reported in the income statement consist of current taxes on profits and deferred taxes. Taxes on amounts recognised directly in equity are also posted to equity. Current taxes are estimated on the basis of the taxable result. They are calculated at the tax rates currently in force. Any differences on the tax accounts for previous years are also included in current taxes. Deferred taxes are determined on the basis of the timing differences arising between the tax bases of assets and liabilities and their carrying values (Balance Sheet Liability Method). Deferred taxes are determined based on the fiscal legislation and the tax rates in force at the balance sheet date or announced and expected to apply at the time of the realisation of the asset, or when the deferred tax liability is settled.

Deferred tax assets are recognised on the balance sheet to the extent that it is probable that future taxable profits will be available to offset the taxable losses carried forward. Deferred tax liabilities are provided on timing differences arising on investments in subsidiaries and associates, except where the timing of the reversal of the timing difference is controlled by the Group and it is probable that the timing difference will not reverse in the foreseeable future. Earning per share Earning per share is calculated by dividing the Group result attributable to the shareholders of Implenia Ltd by the average weighted number of shares in circulation during the period concerned. To date, there are no factors that would require the calculation of a diluted result per share. Consolidated balance sheet Cash and cash equivalents Cash and cash equivalents include cash, assets held in current accounts (with the post office and banks), and deposits with a term of less than 90 days. Trade debtors The carrying value represents the amounts invoiced after deducting allowance for doubtful debts. The allowance is recognised in the income statement. Work in progress Expenses related to orders are recorded at the time they occur. If the result of an order cannot be estimated reliably, income is recorded only up to the amount of the recoverable estimated expenses. If the result of an order can be estimated reliably and if the final estimated result is a profit, the order is valued at the net selling price, according to the Percentage of Completion Method. When it appears probable that the total costs of an order will exceed the expected income, the total amount of expected loss is recognised immediately in the income statement. The percentage of completion is expressed as a percentage of the costs incurred up to the balance sheet date in relation to the total expected costs to completion of the project.

Consolidated Financial Statements of the Implenia Group Notes to the Consolidated Financial Statements 15

Each order is valued individually, and the valuation is based on the estimated result at completion. Work in progress consists of work not yet invoiced to customers and services and work not yet invoiced by suppliers and subcontractors, as well as provisions for losses on the order book, if any (negative margins and provision for any overheads not recoverable). The valuation adjustments are determined individually project by project. The net balance, by project, of these adjustments is disclosed as an asset if it is positive, or a liability if it is negative. Work partnerships This balance sheet item includes debtors and creditors in relation to work partnerships (advances made and received, debtors and creditors on current account, share in the result not distributed). A single asset or liability is reported on the balance sheet in relation to each work partnership. Work partnerships are valued in a similar way as work in progress. Inventories Inventories are valued at the lower of cost and net realisable value at the balance sheet date (including the purchase costs but not taking into account selling costs). Inventory costs are taken to the income statement at their weighted average cost. Real estate operations The real estates classified under this heading consist of properties held for sale in the ordinary course of business and valued like “Inventories” according to IAS 2. Completed operations not yet sold, may temporarily generate rental income. They continue to be classified under this heading as they are intended to be sold. Some real estate operations are conducted jointly with one or more partners. The operations that are carried on under joint control and ownership are reported as Real estate operations in the balance sheet for the share pertaining to Implenia, but as a maximum at the value of the funds invested.

Each transaction is measured individually. The valuation is stated at the lower of the construction cost of the property and its market value estimated by the Group’s real estate specialists. The construction cost includes the borrowing costs paid to third parties until the property is ready for use or sale. Impairment resulting of the above valuation principles are deducted from the carrying value as a valuation adjustment. Net result from the sale of real estate operations and changes in the relevant valuation adjustments are included in turnover. Tangible fixed assets Tangible fixed assets are stated at their acquisition or production cost, after deducting depreciation and any impairment. Borrowing costs are capitalized only if financing has been specifically obtained for the asset. Improvement investments are capitalized only if they increase the value or if they replace a complete part of the asset and if the replaced part is derecognized from the inventory. Other expenses related to tangible fixed assets are recognised directly in the income statement. Depreciation is charged using the estimated useful life of the fixed asset. Fixed assets that are important in value are divided into significant components with different useful lives. Depreciation is recorded separately for each component according to its useful life. The main depreciation periods are as follows: – Business premises 25-50 years – Investment properties 25-50 years – Production units 15-20 years – Machinery and vehicles 06-15 years – Furniture 05-10 years – IT equipment 03-50 years The residual values and useful lives are checked every year. If the current estimate changes from previous assessment, the resulting value adjustments are recognised in the income statement in the period when the change occurs in accordance with IAS 8. Gains and losses on disposal represent the difference between the book value and the sales proceeds, if any. Tangible fixed assets are derecognised at the time of sale or when it is determined that the asset no longer represents a future economic value.

Leasing Lease agreements that substantially transfer to Implenia all the risks and rewards incidental to ownership are classified as finance lease. All other lease agreements are classified as operating lease. The decision as to whether a lease agreement is an operating or finance lease is made on an individual basis, according to the principles of IAS 17. Properties under finance leases are recognised on the balance sheet at the discounted value of the minimum leasing payments or if lower at market value. Lease payments are apportioned between the finance charges and reduction of the lease liability so as to achieve a constant rate of interest on the remaining balance of the liability. Fixed assets acquired through finance leases are depreciated over their estimated useful life or over the duration of the lease agreement, if it is shorter. The charges for operating lease agreements are included in the income statement at the time of payment. Long-term investments The valuation of minority shareholdings is presented under the heading “Basis of Consolidation; Minority shareholdings”. Long-term loans and receivables are recorded initially at their fair value and subsequently measured at amortised cost, less any allowance for unrecoverable amounts. The allowance is recorded in the income statement. Intangible assets a) Licenses and software Software is recorded at purchase cost after deducting the accumulated depreciation and any impairment. Depreciation is calculated using the straight line method based on the estimated useful life, not exceeding 5 years.

b) IT Projects The costs incurred for IT projects are included on the balance sheet as intangible assets only if it is considered probable that they can be exploited commercially and are technically feasible, and the costs can be determined reliably. Other development expenses that do not satisfy these conditions are recognised in the income statement as they occur. As a maximum, the costs are capitalised for an amount corresponding to the discounted income from their future use. The development costs recognised are depreciated on a straight line basis over an estimated useful life between 3 and 6 years. Development expenses once recorded as expenses cannot be included as an asset in subsequent years. c) Goodwill In a business combination, goodwill represents the difference between the cost of acquisition and the fair value of the share in the net assets of the acquired company at the time of the acquisition. In the case of negative goodwill (if the value of the net assets exceeds the acquisition price), the amount is recognised directly in the income statement. Goodwill resulting from the acquisition of an associated company is included in the book value and is disclosed under “Investment in associated companies”. Goodwill recognised on the balance sheet is subject to impairment tests conducted annually and whenever there are indications of a potential impairment. Goodwill is stated at the acquisition cost less accumulated impairment losses. For the purpose of impairment testing, goodwill is allocated to cash generating units or groups of units that are expected to benefit from the advantages that gave rise to the goodwill. d) Trademarks Acquired trademarks are stated at their acquisition cost less accumulated depreciation. Depreciation is calculated on a straight line basis, over the estimated useful life of 1 to 5 years.

Consolidated Financial Statements of the Implenia Group Notes to the Consolidated Financial Statements 17

e) Customer lists and order books Acquired customer lists and order books are stated at their acquisition cost less accumulated depreciation. Depreciation is calculated on a straight line basis, over the estimated useful life of 1 to 5 years. Impairment of tangible and intangible fixed assets Fixed assets are examined annually to detect any indications of a permanent reduction of value. If such indications do exist, the recoverable amount of the fixed asset is determined on the basis of an impairment test. Intangible assets with indefinite useful life (such as goodwill, for example) are systematically subject to annual impairment tests. The recoverable amount is the higher of the fair value less cost to sell, and the value in use. An impairment is charged to the income statement if the carrying value of the fixed asset or the cash generating unit exceeds the recoverable amount. With the exception of Goodwill, non monetary fixed assets whose value has been impaired previously are reviewed at each balance sheet date to determine any potential reversal of impairment. Financial liabilities Financial liabilities are initially recognised at the actual cost less transaction costs and subsequently measured by using the effective interest rate method. The difference between the amount borrowed and the amount to be repaid is recognised in the income statement over the period of the borrowing. Provisions Provisions are recognised when at the date of the financial statements: â&#x20AC;&#x201C; The Group has a present legal or constructive obligation resulting from a past event; â&#x20AC;&#x201C; it is probable that a transfer of economic resources will be necessary to settle the obligation; â&#x20AC;&#x201C; a reliable estimate can be made of the amount of the obligation. If the effect of the time value of money is material, the amount of the provision is appropriately discounted.

Pension plans The employees of Group companies are affiliated to autonomous and independent pension plans. These plans are financed by regulatory contributions paid by both employers and employees. The assets of the pension plans are managed independently and are completely separated from the Group. The benefit obligations are calculated every year by an independent actuary. In relation to the application of the international accounting standard IAS 19, the Group's pension plans are considered to be defined benefit pension plans, although, according to the interpretation given in Switzerland, they are considered as mixed plans. The balance-sheet provision corresponds to the discounted value of any future defined benefit obligation (DBO) as at the balance-sheet date, after deducting the fair value of long-term assets, adjusted for the accumulated actuarial differences which fall outside of the corridor, to be depreciated over the remaining number of years of service. The liabilities are calculated periodically using the projected unit credit method by an independent actuary. The value of the liabilities is determined by discounting the expected future cash flows. The discount rate used is the market rate for top quality industrial debtors. Actuarial gains and losses due to experience adjustments and changes made in the actuarial assumptions are recognised over the expected average remaining working lives of the employees to the extent that they fall outside of the corridor at the end of the previous period. The cost of past services is recorded on a straight line basis over the average remaining working lives until the benefits corresponding to the adopted or modified scheme become due to the employees.

Other employee benefits Group executives benefit from a profit-sharing plan in shares. It may be considered as supplementary remuneration linked to the result of the year concerned and takes the form of a free distribution of shares or shares offered at a preferential purchase price. These benefits (the difference between the stock market value of the shares distributed and the amounts received for the shares) are reported as personnel charges. The charges related to shares that are distributed only during the following year are provided for and recognised at 100% in the year concerned, as this remuneration is not related to the future performance of the executives. The details are defined from year to year by the Board of Directors. All the employees of the Group enjoy the benefit of a profit-sharing plan in shares managed according to the regulations of the Motivation Foundation. Under the framework of this plan, the employees can acquire, once a year, a fixed number of Implenia Ltd shares at a preferential price. The difference between the stock market value of the shares distributed and the amounts received for the shares is charged to the Group units concerned and reported in the consolidated accounts as personnel expenses in the year when the shares are allocated. Equity The share capital consists of all issued registered shares. Dividends are recognised when the entitlement to their payment arises. External transaction costs related directly to the issue of share capital are deducted directly from the capital reserves. The acquisition by Implenia Ltd of treasury shares or those of the affiliated companies is recognised as a reduction of equity at the purchase cost, including transaction expenses. The income from the resale of these treasury shares is also recognised in equity.

Management of financial risks Credit risk Credit risk essentially result of the credit worthiness of the main financial assets (cash and cash equivalents, trade debtors, short and long-term financial debtors). Cash and cash equivalents consist essentially of assets in current accounts and short-term deposits with banks. Trade debtors and short and long-term financial debtors are checked regularly with regard to their credit worthiness. If necessary, impairment adjustments are recorded. Market risk Implenia is subject, like all other market companies, to the effects of general economic conditions as well as to the specific factors affecting the Swiss construction industry. These include notably the dependence on the business trend, the cyclic nature of the construction industry in general and particularly in Switzerland, the strong competition by Swiss and foreign contractors, and the risks related to private and public tenders. Foreign currency risk The Implenia Group is not exposed to a significant foreign currency exchange risk, as both purchases and sales are invoiced in the supplier's national currency. Similarly, financial loans and debts are granted or contracted in the local currency. Interest rate risk The Implenia Group is only exposed to a limited interest rate risk, as long-term financial assets and liabilities are generally subject to fixed interest rates and repricing terms are fixed only for a small part of them. No long-term financial liabilities exist at variable interest rates. Actual interest rates usually correspond to the standard rates. Price Risk The carrying amounts relating to cash and cash equivalents, financial assets, trade debtors and other debtors, as well as those related to financial liabilities correspond essentially to market values.

1. Consolidation Scope 1.1. Acquisition of Batigroup On 2 March 2006, the group acquired 100% of Batigroup, a Swiss group active in the construction sector. From a legal standpoint, Zschokke and Batigroup were merged to form Implenia Ltd. According to IFRS 3, the Zschokke Group was designated as the acquiring company. The acquired company has contributed CHF 759 million to turnover and CHF 15.8 million to the annual result of the Group. If the combination had taken place at the beginning of the year, the company would have contributed to the Group turnover for CHF 851 million and to the operating result for CHF 17.7 million; these figures were calculated on the basis of the methods used to value and draw up the Group accounts. Where necessary, the results have been adjusted to take account of the depreciation of fixed and intangible assets, as well as the relevant tax effects, as though the takeover had been made on 1st January 2006. As the Zschokke Group was designated as the acquiring company, all the comparative figures contained in this report are from the 2005 report issued by the Zschokke Group. The values calculated below may differ from the provisional values presented in our report as at 30 June 2006. Additional adjustments have been made in the accounts on the basis of the analyses of the final figures. The acquisition cost and the corresponding goodwill can be broken down as follows: Value of Implenia shares issued Purchase price of the 4.03% of Batigroup shares purchased by Zschokke in 2005 Transaction costs Total acquisition costs Fair value of the net assets acquired (details below) Goodwill

(in million CHF) 159.6 4.7 3.9 168.2 104.8 63.4

For the purpose of the acquisition, a total of 6 185 046 Implenia shares with a market value of CHF 25.80 each were distributed in exchange of the existing 6 185 046 Batigroup Holding Ltd share. Goodwill was apportioned among the following Cash Generating Units: Implenia Bau AG – Construction Implenia GU AG – General Contractor Stamm Bau AG – Construction (see note below) Total Goodwill

Goodwill represents the value of the staff of Batigroup as well as the synergies expected from the group merger.

20. Goodwill valuation and distribution In accordance with IFRS 3, the net book value of Goodwill represents the excess of the cost of acquisition over the fair value of the acquired identifiable assets, liabilities and contingent liabilities, under deduction of accumulated impairment losses. Goodwill is allocated to the respective cash generating units (CGU). The goodwill resulting from the acquisition of Batigroup is allocated over the new legal entities resulting from the internal reorganisation. The net residual value of a CGU is determined based on a value in use calculation of discounted cash flows, taking into account the business plan 2007 to 2009 adopted by the management. Subsequent years cash flows are estimated based on growth rates as disclosed below.

Consolidated Financial Statements of the Implenia Group Notes to the Consolidated Financial Statements 35

The Goodwill is distributed between the CGUs as follows: (in 1000 CHF)

The main source of financing is the consortium credit that the Group obtained from a consortium of banks on 16 August 2006. The total credit limit amounts to CHF 500 million and will be valid until the end of 2009. The limit is split up between a cash limit of CHF 200 million and a limit for the issue of guarantees of CHF 300 million. To secure the consortium credit, the Implenia Group issued the following securities in favour of the bank consortium: – Pledging of mortgage certificates on the Group real estate for a market value of CHF 40 million. – Guarantees given by the most important companies of the Group to cover the obligations of Implenia Ltd towards the bank consortium. The continuance of the credit relationships is dependant on various conditions (Covenants), which had been fully complied with by Implenia Ltd at 31 December 2006.

a) Scheme available to all employees The profit-sharing scheme for the benefit of employees is determined by the Motivation Foundation of Implenia Group (2005: Zschokke). Under this scheme, employees can subscribe to shares of Implenia Ltd (2005 and 2006 Zschokke Holding SA) at a preferential price. The difference between the average market price of CHF 562.99 per share (2005: CHF 551.21 per share) and the preferential price of CHF 400 per share (2005: CHF 300 per share) is recorded as an expense of the period.

The shares are blocked and cannot be traded for a period of 5 years. The employees are entitled to dividends and may exercise their voting rights. Upon expiry of the blocking period, the shares may be freely traded by the employees. b) Executive scheme The Groupâ&#x20AC;&#x2122;s executives benefit from a profit-sharing scheme based on shares of Implenia Ltd (2005: Zschokke Holding SA). Depending on goal achievement, the Board of Directors may decide to grant shares free of charge or on a preferential basis. Under a written agreement, this share grant is considered to be a supplementary annual remuneration that is not related to the future performance of the executives. The amount is therefore expensed entirely in the current financial year. The amount charged to the Group is calculated on the basis of the stock market value of the share at the time of the grant, which, in principle, is made at the beginning of the following year. The Group may either buy shares on the market or it may draw them from its own portfolio of treasury shares. In 2006, shares reserved to executives have been attributed at a price of CHF 25.45 per share (2005: CHF 818.50 per share). The listed price at the time of grant amounted to CHF 25.45 per share (2005: CHF 835.20 per share). Share grant Amount expensed for the financial year

33. Post-balance sheet events The Board of Directors of Implenia Ltd, in its meeting held on 15 March 2007, approved the consolidated accounts for the year 2006 for presentation to the ordinary general meeting of shareholders on 24 April 2007. The general meeting is deciding on the final approval of the financial statements. Up to the time of the approval of this report, there were no known events that might require an adjustment to the accounting values of the Groups assets and liabilities. Subsequent to the date of the balance sheet, the following significant change has occured in the operating structure of the Group. The “General Contractor” segment was integrated into “Real Estate”, headed by Hans-Peter Domanig. This decision was taken to better address the potential of the market and concentrate all the services surrounding the value chain of a real estate. The concept of a “Corporate Center” is currently under preparation. The details about its future structure will be communicated in the course of the second half of 2007.
