The rates quoted represent the statutory federal income tax rates in each territory, and do not include any state taxes or equivalents or surtaxes or other taxes charged in individual territories, and do not purport to represent the effective tax rate for the Company in each territory.

[2] Intra-group items principally relate to the effect of inter-company dividends and other intra-territory eliminations, the pre-tax effect of which has been eliminated in arriving at the Company’s consolidated income from continuing operations before income taxes, noncontrolling interests and equity in earnings/(losses) of equity method investees.
