A N N U A L R E P O R T - Bouygues

AUDITORS’ REPORT ON THE CONSOLIDATED FINANCIAL STATEMENTS
Ladies and gentlemen,
In accordance with the terms of our appointment
at your Annual General Meeting, we have
audited the consolidated financial statements of
Bouygues for the year ended 31 December 2005
as attached to this report.
The consolidated financial statements are the
responsibility of the Board of Directors. Our
responsibility is to express an opinion on them
based on our audit. These financial statements
have been prepared for the first time in accordance
with IFRS as adopted in the European
Union. For comparison purposes, they contain
figures relating to 2004 that have been adjusted
to reflect the impact of these accounting standards.
I - Opinion on the consolidated
financial statements
We conducted our audit in accordance with
the professional standards applicable in France.
Those standards require that we plan and perform
our audit to obtain reasonable assurance that the
consolidated financial statements are free of
material misstatement. An audit includes examining,
on a test basis, evidence supporting the
amounts in the accounts. An audit also includes
assessing the accounting principles used and significant
estimates made in the preparation of the
financial statements and evaluating their overall
presentation. We believe that our audit provides
a reasonable basis for our opinion.
In our opinion, the 2005 consolidated financial
statements give a true and fair view, according
to IFRS as adopted in the European Union, of
the assets, financial situation and results of the
group formed by the persons and entities within
the scope of consolidation.
II - Substantiation of our
opinion
Pursuant to the provisions of Article L. 823-9 of
the Commercial Code concerning substantiation
of our opinion, we bring to your attention the
following items of information:
Loss-of-value tests were carried out on intangible
fixed assets and goodwill as described in note
2.6.4 of the notes to the consolidated financial
statements. We examined the methods for carrying
out the tests and the assumptions on which
they were based.
Current and non-current provisions appearing on
the balance sheet in amounts of €676 million and
€1,265 million respectively were valued using the
rules and methods described in notes 2.11.2 and
2.10.2 to the consolidated financial statements. In
the light of the information available to date, our
assessment of the provisions is based in particular
on an analysis of the processes used by senior
management to identify and assess the risks.
The assessments thus made form part of our
audit of the consolidated financial statements
taken as a whole and have thus contributed to
the formation of our opinion expressed without
qualification in the first part of this report.
III - Specific verifications
We have also examined the information contained
in the Board of Directors’ business report
in accordance with the prevailing standards of
the profession in France. We are satisfied that
the information is fairly stated and agrees with
the consolidated financial statements.
