Segment reporting, described below, is structured on a primary basis by business segment and on
a secondary basis by geographical segment. This structure is in line with the information used
internally by Acciona Group management to assess the performance of the segments and to assign
resources among them.
The business lines described below were established by the Board of Directors on the basis of the
Acciona Group's organisational structure, taking into account the nature of the goods and services
offered.
In 2011 the main business activities carried on by the Acciona Group were structured into the
divisions described in Note 1 to the consolidated financial statements. The composition and
structure of the various lines of business did not change significantly with respect to 2010.
The reporting structure is designed as if each line of business were an autonomous business. The
costs incurred by the Corporate Unit are allocated among the various lines of business using an
internal cost allocation system.
