B. Consolidation and Basis of Presentation. The Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles (“GAAP”) in the U.S. and in accordance with the U.S. SEC requirements for Annual Reports on Form 10-K. These financial statements present the consolidated position of the Company and include the entities in which the Company directly or indirectly has a controlling financial interest as well as various entities in which the Company has investments recorded under the equity method of accounting as well as certain marketable and non-marketable securities. Intercompany balances and transactions have been eliminated. Amounts presented may not sum due to rounding. Certain prior period amounts have been reclassified to conform to the current year presentation, except as it relates to (i) Financial Accounting Standards Board (the “FASB”) Accounting Standards Update (“ASU”) No. 2014-09 “Revenue from Contracts with Customers” and its related amendments (collectively “ASU No. 2014-09”), (ii) ASU No. 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU No. 2016-01”), (iii) ASU No. 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” (“ASU No. 2018-02”), and (iv) ASU No. 2016-09 “Improvements to Employee Share-Based Payment Accounting” (“ASU No. 2016-09”), as described further below. Effective July 1, 2018, the Company adopted ASU No. 2014-09 using the modified retrospective transition approach applied to all contracts. Under this transition approach, the Company has not restated the prior period Consolidated Financial Statements presented to the current period presentation. However, the Company has provided additional disclosures related to the amount by which each relevant fiscal 2019 financial statement line item was affected by the adoption of ASU No. 2014-09 along with explanations for significant changes. Additional information about the Company’s revenue recognition policies and the related impact of the adoption of ASU No. 2014-09 is included in Note 2, “Summary of Significant Accounting Policies” and Note 3, “Revenue Recognition”. Effective July 1, 2018, the Company adopted ASU No. 2016-01, which requires changes in the fair value of publicly traded equity securities for which the Company does not have significant influence to be recorded as part of Net earnings rather than as Other comprehensive income (loss), net. In addition, equity investments that do not have a readily determinable fair value will be recorded at cost less impairment as further adjusted for observable price changes in orderly transactions for identical or similar investments of the issuer. The Company adopted ASU No. 2016-01 using the modified-retrospective transition approach by recording the cumulative effect of previously unrecognized gains or losses on publicly traded equity securities to retained earnings as of July 1, 2018. The provisions of ASU No. 2016-01 relative to equity investments that do not have a readily determinable fair value have been applied prospectively. The Consolidated Financial Statements have not been revised for periods prior to July 1, 2018. The impact of adopting ASU No. 2016-01 resulted in a reclassification of less than $0.1 million in unrealized gains, net from accumulated other comprehensive loss to retained earnings as of July 1, 2018. Effective July 1, 2018, the Company adopted ASU No. 2018-02, which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects associated with the change in the U.S. federal corporate tax rate resulting from the U.S. Tax Cuts and Jobs Act (the “Tax Act”) enacted in December 2017. The adoption of ASU No. 2018-02 resulted in an increase to retained earnings of $1.5 million. Effective July 1, 2018, the Company adopted ASU No. 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” (“ASU No. 2017-07”) whereby the Company revised its presentation in the Consolidated Statements of Earnings to reflect the non-service cost components of net benefit cost as part of Other non-operating income (expenses), net, which were previously recorded as part of Total operating expenses. All prior period information has been conformed to the current period presentation. Effective July 1, 2017, the Company adopted ASU No. 2016-09, which identifies areas for simplification involving several aspects of accounting for share-based payment transactions, including presenting the excess tax benefits (“ETB”) or deficits from the exercise or vesting of share-based payments in the income statement, classifying the ETB or deficits as an operating activity in the Consolidated Statements of Cash Flows rather than as a financing activity, a revision to the criteria for classifying an award as equity or liability and an option to recognize gross stock-based compensation expense with actual forfeitures recognized as they occur. In addition, ASU No. 2016-09 eliminates the ETB from the assumed proceeds calculation under the treasury stock method for purposes of calculating diluted shares. As a result of this adoption, the Company recorded ETB related to stock-based compensation awards of $19.3 million and $40.9 million during the fiscal years ended June 30, 2019 and 2018 in the income tax provision on a prospective basis, whereas such benefits would previously have been recognized in equity. The Company also excluded the ETB from the assumed proceeds available to repurchase shares in the computation of diluted earnings per share for the fiscal years ended June 30, 2019 and 2018. The Company has not adjusted prior periods presented for the change in accounting for ETB in the Consolidated Financial Statements. The Company also elected to apply the change in presentation of ETB in the Consolidated Statement of Cash Flows prospectively, and as a result, ETB are classified as operating activities when realized through reductions to subsequent tax payments. This adoption resulted in an increase to net cash provided by operating activities and a corresponding decrease to net cash provided by financing activities of $19.3 million and $40.9 million for the fiscal years ended June 30, 2019 and 2018. The Company has not adjusted prior periods presented for the change in classification of ETB on the Consolidated Statement of Cash Flows. The Company also elected to continue its current practice of estimating expected forfeitures as permitted by ASU No. 2016-09.
