[2] Cloud and license revenues and total revenues presented for management reporting for fiscal 2021 and fiscal 2020 included revenues related to cloud and license obligations that would have otherwise been recorded by the acquired businesses as independent entities but were not recognized in our consolidated statements of operations due to business combination accounting rules that were applicable to acquisitions closed prior to fiscal 2022. The table below provides a reconciliation of our total operating segment revenues to our total revenues as reported in our consolidated statements of operations for all periods presented.
