17. Reportable Operating Segments

We are a globally integrated payments company that is principally engaged in businesses comprising three reportable operating segments: GCSG, GCS and GMNS. Corporate functions and certain other businesses and operations are included in Corporate & Other. Effective January 1, 2018, we changed the methodology used to allocate certain corporate overhead costs and interest income and expense to the operating segments. Effective April 1, 2018, we made additional changes to the methodology used to allocate certain corporate overhead costs to the operating segments. Prior period amounts have been revised to conform to the current period presentation.

The following table presents certain selected financial information for our reportable operating segments and Corporate & Other:
