Basis of Presentation The Company’s consolidated financial statements include the accounts of the Company and its wholly-owned and majority-owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. Investments in affiliated companies in which the Company exercises significant influence, but which it does not control, are accounted for under the equity method of accounting. As such, consolidated net income includes the Company’s equity in the current earnings or losses of such companies. On December 29, 2014, the Company effected a two-for-one stock split of its common stock in the form of a 100% stock dividend to shareholders of record as of December 12, 2014. All share and earnings per share information have been retroactively adjusted to reflect the stock split and the incremental par value of the newly issued shares was recorded with the offset to additional paid-in capital. Unless otherwise indicated, references in these consolidated financial statements to 2016, 2015 and 2014 or “fiscal” 2016, 2015 and 2014 or other years refer to our fiscal year ended June 30 of that respective year and references to 2017 or “fiscal” 2017 refer to our fiscal year ending June 30, 2017. Use of Estimates The financial statements are prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). The accounting principles we use require us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and amounts of income and expenses during the reporting periods presented. These estimates include, among others, revenue recognition, trade promotions and sales incentives, valuation of accounts and chargeback receivables, accounting for acquisitions, valuation of long-lived assets, goodwill and intangible assets, stock-based compensation, and valuation allowances for deferred tax assets. We believe in the quality and reasonableness of our critical accounting estimates; however, materially different amounts may be reported under different conditions or using assumptions different from those that we have consistently applied. Accounting Review During the fourth quarter of fiscal 2016, the Company identified the practice of granting additional concessions to certain distributors in the United States and commenced an internal accounting review in order to (i) determine whether the revenue associated with those concessions was accounted for in the correct period and (ii) evaluate its internal control over financial reporting. The Audit Committee of the Company’s Board of Directors separately conducted an independent review of these matters and retained independent counsel to assist in their review. On November 16, 2016, the Company announced that the independent review of the Audit Committee was completed and that the review found no evidence of intentional wrongdoing in connection with the preparation of the Company’s financial statements. The aforementioned reviews identified material weaknesses in our internal control over financial reporting. We refer the reader to “Part II, Item 9A. Controls and Procedures,” for a description of these material weaknesses and management’s plan and implementation of remediation efforts to address these material weaknesses. Management’s accounting review included consideration of certain side agreements and concessions provided to distributors in the United States, including payment terms beyond the customer’s standard terms, rights of return of product and post-sale concessions, most of which were associated with sales that occurred at the end of the quarter. It had been the Company’s policy to record revenue related to these distributors when title of the product transfers to the distributor. The Company concluded that its historical accounting policy for these distributors is appropriate as the sales price is fixed or determinable at the time ownership transfers to these distributors, based on the Company’s ability to make a reasonable estimate of future returns and certain concessions at the time of shipment. Although the initial focus of the Company’s internal accounting review discussed above pertained to the evaluation of the timing of the recognition of the revenue associated with the practice of granting additional concessions to certain distributors, the Company subsequently expanded its internal accounting review and performed an analysis of previously-issued financial statements in order to identify and assess other potential errors. Based upon this review, the Company identified certain immaterial errors relating to its previously-issued financial statements which resulted in revisions to our previously-issued financial statements and are discussed in further detail under Note 2, Correction of Immaterial Errors to Prior Period Financial Statements. Revisions As discussed above, the Audit Committee’s independent review and the internal accounting review conducted by the Company identified immaterial errors that impacted our previously issued consolidated financial statements. Accordingly, prior period amounts presented in the consolidated financial statements and the related notes have been revised (referred to as the “Revision”). See Note 2, Correction of Immaterial Errors to Prior Period Financial Statements, for a more detailed description of the Revision and for comparisons of amounts previously reported to the revised amounts.

Basis of Presentation

The Company’s consolidated financial statements include the accounts of the Company and its wholly-owned and majority-owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. Investments in affiliated companies in which the Company exercises significant influence, but which it does not control, are accounted for under the equity method of accounting. As such, consolidated net income includes the Company’s equity in the current earnings or losses of such companies.

On December 29, 2014, the Company effected a two-for-one stock split of its common stock in the form of a 100% stock dividend to shareholders of record as of December 12, 2014. All share and earnings per share information have been retroactively adjusted to reflect the stock split and the incremental par value of the newly issued shares was recorded with the offset to additional paid-in capital.

Unless otherwise indicated, references in these consolidated financial statements to 2016, 2015 and 2014 or “fiscal” 2016, 2015 and 2014 or other years refer to our fiscal year ended June 30 of that respective year and references to 2017 or “fiscal” 2017 refer to our fiscal year ending June 30, 2017.

Use of Estimates

The financial statements are prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). The accounting principles we use require us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and amounts of income and expenses during the reporting periods presented. These estimates include, among others, revenue recognition, trade promotions and sales incentives, valuation of accounts and chargeback receivables, accounting for acquisitions, valuation of long-lived assets, goodwill and intangible assets, stock-based compensation, and valuation allowances for deferred tax assets. We believe in the quality and reasonableness of our critical accounting estimates; however, materially different amounts may be reported under different conditions or using assumptions different from those that we have consistently applied.

Accounting Review

During the fourth quarter of fiscal 2016, the Company identified the practice of granting additional concessions to certain distributors in the United States and commenced an internal accounting review in order to (i) determine whether the revenue associated with those concessions was accounted for in the correct period and (ii) evaluate its internal control over financial reporting. The Audit Committee of the Company’s Board of Directors separately conducted an independent review of these matters and retained independent counsel to assist in their review. On November 16, 2016, the Company announced that the independent review of the Audit Committee was completed and that the review found no evidence of intentional wrongdoing in connection with the preparation of the Company’s financial statements. The aforementioned reviews identified material weaknesses in our internal control over financial reporting. We refer the reader to “Part II, Item 9A. Controls and Procedures,” for a description of these material weaknesses and management’s plan and implementation of remediation efforts to address these material weaknesses.

Management’s accounting review included consideration of certain side agreements and concessions provided to distributors in the United States, including payment terms beyond the customer’s standard terms, rights of return of product and post-sale concessions, most of which were associated with sales that occurred at the end of the quarter. It had been the Company’s policy to record revenue related to these distributors when title of the product transfers to the distributor. The Company concluded that its historical accounting policy for these distributors is appropriate as the sales price is fixed or determinable at the time ownership transfers to these distributors, based on the Company’s ability to make a reasonable estimate of future returns and certain concessions at the time of shipment.

Although the initial focus of the Company’s internal accounting review discussed above pertained to the evaluation of the timing of the recognition of the revenue associated with the practice of granting additional concessions to certain distributors, the Company subsequently expanded its internal accounting review and performed an analysis of previously-issued financial statements in order to identify and assess other potential errors. Based upon this review, the Company identified certain immaterial errors relating to its previously-issued financial statements which resulted in revisions to our previously-issued financial statements and are discussed in further detail under Note 2, Correction of Immaterial Errors to Prior Period Financial Statements.

Revisions

As discussed above, the Audit Committee’s independent review and the internal accounting review conducted by the Company identified immaterial errors that impacted our previously issued consolidated financial statements. Accordingly, prior period amounts presented in the consolidated financial statements and the related notes have been revised (referred to as the “Revision”). See Note 2, Correction of Immaterial Errors to Prior Period Financial Statements, for a more detailed description of the Revision and for comparisons of amounts previously reported to the revised amounts.
