Transactions between segments, which were eliminated in consolidation, are mainly related to sales of scrap, energy, surplus raw materials and others from the Other segment to the Tubes segment for $16.9, $36.2 and $52.4 million in 2020, 2019 and 2018, respectively.

There are no material differences between IFRS and management view in total revenues and by reportable segments.

The main differences between operating income under IFRS view and the management view are mainly related to the cost of goods sold and other timing differences. See Section II.C - Segment Information. The main difference in Other operating income (expenses), net is attributable to the impairment of the goodwill, which residual value in the management view differs from IFRS.

In addition to the amounts reconciled above, the main differences in net income arise from the impact of functional currencies on financial result, deferred income taxes as well as the result of investment in non-consolidated companies.
