The selected consolidated financial data should be read in conjunction with our Consolidated Financial Statements and related notes and “Management's Discussion and Analysis of Financial Condition and Results of Operations” appearing elsewhere in this Annual Report on Form 10-K. The selected consolidated statement of income and balance sheet data for each of the five fiscal years indicated below has been derived from our audited Consolidated Financial Statements. Over the last five fiscal years we have acquired a number of companies including, but not limited to Catalyst, Liaison, Hightail, Guidance, Covisint, ECD Business, CCM Business, Recommind, ANX, CEM Business, Daegis, and Actuate. The results of these companies and all of our previously acquired companies have been included herein and have contributed to the growth in our revenues, net income and net income per share and such acquisitions affect period-to-period comparability. (1) Effective July 1, 2018, we adopted Accounting Standards Codification (ASC) Topic 606 "Revenue from Contracts with Customers" (Topic 606) using the cumulative effect approach. We applied the standard to contracts that were not completed as of the date of the initial adoption. Results for reporting periods commencing on July 1, 2018 are presented under the new revenue standard, while prior period results continue to be reported under the previous standard. (2) Fiscal 2017 included a significant one-time tax benefit of $876.1 million recorded in the first quarter of Fiscal 2017.
