[1] | (1) On January 1, 2018, the Company adopted accounting standard ASU 2014-09, Revenue from Contracts with Customers and all related amendments (Topic 606), applying the modified retrospective transition method to all customer contracts that were not completed as of January 1, 2018. Results for reporting periods beginning after December 31, 2017 are presented under ASU 2014-09, while prior period amounts are not adjusted and continue to be reported under the accounting standards in effect for the prior period. As a result, the allowance for returns has been reclassified from "Accounts receivable, net" to "Other current liabilities." For more information, see "Note 2. Recent Accounting Pronouncements and Adopted Accounting Standards" to the consolidated financial statements contained in Part II, Item 8. of this report.
