Basis of Presentation [Abstract]
Basis of Presentation	In the opinion of management, the accompanying unaudited interim consolidated financial statements contain all normal and recurring adjustments necessary to present fairly the consolidated financial position of Hasbro, Inc. and all majority-owned subsidiaries ("Hasbro" or the "Company") as of September 30, 2018 and October 1, 2017, and the results of its operations and cash flows for the periods then ended in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and notes thereto. Actual results could differ from those estimates. The quarters ended September 30, 2018 and October 1, 2017 were each 13-week periods. The nine-month period ended September 30, 2018 was a 39-week period while the nine-month period ended October 1, 2017 was a 40-week period. The results of operations for the quarter and nine-month periods ended September 30, 2018 are not necessarily indicative of results to be expected for the full year, nor were those of the comparable 2017 periods representative of those actually experienced for the full year 2017. Certain reclassifications have been made to prior year amounts to conform to the current period presentation. These condensed consolidated financial statements have been prepared without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and disclosures normally included in the consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The Company filed audited consolidated financial statements for the fiscal year ended December 31, 2017 in its Annual Report on Form 10-K (“2017 Form 10-K”), which includes all such information and disclosures and, accordingly, should be read in conjunction with the financial information included herein. Recently Adopted Accounting Standards The Company's accounting policies are the same as those described in Note 1 to the Company's consolidated financial statements in its 2017 Form 10-K with the exception of the accounting policies related to revenue recognition, reclassification of disproportionate tax effects from accumulated other comprehensive income (“AOCI”) caused by the Tax Cuts and Jobs Act of 2017, the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost and Business Combinations, Clarifying the Definition of a Business. On January 1, 2018, the Company adopted Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (ASC 606 or the “New Revenue Standard”) using the modified retrospective method. ASC 606 supersedes the revenue recognition requirements in ASC 605 – Revenue Recognition and most industry-specific guidance in U.S. GAAP. The New Revenue Standard provides a five-step model for analyzing contracts and transactions to determine when, how, and if revenue is recognized. Revenue should be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services. The cumulative impact of the adoption of the New Revenue Standard was not material to the Company therefore the Company did not record any adjustments to retained earnings. This was determined by analyzing contracts not completed as of January 1, 2018. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. For further details, see Note 2. Revenue recognition from the sale of finished product to customers, which is the majority of the Company’s revenues, did not change under the new standard and the Company does not expect material changes in the future as a result of the New Revenue Standard related to the sale of finished product to its customers. Within the Company’s Entertainment and Licensing segment, the timing of revenue recognition for minimum guarantees that the Company receives from licensees is impacted by the New Revenue Standard. Prior to the adoption of ASC 606, for licenses of the Company’s brands that are subject to minimum guaranteed license fees, the Company recognized the difference between the minimum guaranteed amount and the actual royalties earned from licensee merchandise sales (“shortfalls”) at the end of the contract period, which was in the fourth quarter for most of the Company’s licensee arrangements. In periods following January 1, 2018, minimum guaranteed amounts will be recognized on a straight-line basis over the license period. While the impact of this change will not be material to the year, it will impact the timing of revenue recognition within the Company’s Entertainment and Licensing segment such that under ASC 606, less revenues will be recorded in the fourth quarter and more revenues will be recorded within the first, second, and third quarters. No other areas of the Company’s business were materially impacted by the New Revenue Standard. In January 2018, the FASB issued Accounting Standards Update No. 2017-01(“ASU 2017-01”), Business Combinations (Topic 805): Clarifying the Definition of a Business. The standard clarifies the definition of a business with the objective of providing guidance when evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. For public companies, this standard was effective for annual reporting periods beginning after December 15, 2017. For further details, see Note 3. In February 2018, the FASB issued Accounting Standards Update No. 2018-02 (“ASU 2018-02”), Income Statement -Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The standard provides for a reclassification from accumulated other comprehensive earnings (“AOCE”) to retained earnings, of disproportionate income tax effects arising from the impact of the Tax Cuts and Jobs Act of 2017. For public companies, this standard is effective for annual reporting periods beginning after December 15, 2018. Early adoption is permitted. The Company adopted ASU 2018-02 in the first quarter of 2018. The impact of the adoption resulted in a one-time reclassification in the amount of $21,503 from AOCE with a corresponding credit to retained earnings. In March 2017, the FASB issued Accounting Standards Update No. 2017-07 (ASU 2017-07), Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. The standard requires companies to present the service cost component of net benefit cost in the income statement line items where they report compensation cost. Companies will present all other components of net benefit cost outside operating income, if this subtotal is presented. For public companies, this standard was effective for annual reporting periods beginning after December 15, 2017, and early adoption was permitted. The Company adopted this standard in the first quarter of 2018 and the adoption of this standard did not have a material impact on the Company’s results or consolidated financial statements in the quarter or nine-months ended September 30, 2018. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (ASC 230) – Classification of Certain Cash Receipts and Cash Payments. The new guidance is intended to reduce diversity in practice across all industries, in how certain transactions are classified in the statement of cash flows. ASU 2016-15 was effective for public companies for fiscal years beginning after December 15, 2017. The Company adopted this standard in 2018 and the adoption of this standard did not have an impact on the Company’s statement of cash flows for the nine-month periods ended September 30, 2018 and October 1, 2017. In October 2016, the FASB issued Accounting Standards Update No. 2016-16 (ASU 2016-16), Accounting for Income Taxes: Intra-Entity Transfers of Assets Other Than Inventory. For public companies, this standard was effective for annual reporting periods beginning after December 15, 2017, and early adoption is permitted. The standard requires that the income tax impact of intra-entity sales and transfers of property, except for inventory, be recognized when the transfer occurs requiring any deferred taxes not yet recognized on intra-entity transfers to be recorded to retained earnings. The Company adopted this standard in the first quarter of 2018 and the adoption did not have an impact on the Company’s results or consolidated financial statements.

These condensed consolidated financial statements have been prepared without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and disclosures normally included in the consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The Company filed audited consolidated financial statements for the fiscal year ended December 31, 2017 in its Annual Report on Form 10-K (“2017 Form 10-K”), which includes all such information and disclosures and, accordingly, should be read in conjunction with the financial information included herein.
