Financing Arrangements [Abstract]
Financing Arrangements	(7) Financing Arrangements At December 31, 2017, Hasbro had available an unsecured committed line and unsecured uncommitted lines of credit from various banks approximating $1,000,000 and $146,000, respectively. Substantially all of the short-term borrowings outstanding at the end of 2017 and 2016, such as the commercial paper program, represent borrowings made under, or supported by, these lines of credit. Borrowings under the lines of credit were made by certain international affiliates of the Company on terms and at interest rates generally extended to companies of comparable creditworthiness in those markets. The weighted average interest rates of the outstanding borrowings under the uncommitted lines of credit as of December 31, 2017 and December 25, 2016 were 4.32% and 8.17%, respectively. The Company had no borrowings outstanding under its committed line of credit at December 31, 2017. During 2017, Hasbro's working capital needs were fulfilled by cash generated from operations, borrowings under lines of credit and utilization of its commercial paper program discussed below. The unsecured committed line of credit, as amended on March 30, 2015 (the "Agreement"), provides the Company with a $1,000,000 committed borrowing facility through March 30, 2020. During the third quarter of 2017 and pursuant to the Agreement, the Company proposed and the Lenders agreed to increase the committed borrowing facility from $700,000 to $1,000,000. The Agreement contains certain financial covenants setting forth leverage and coverage requirements, and certain other limitations typical of an investment grade facility, including with respect to liens, mergers and incurrence of indebtedness. The Company was in compliance with all covenants as of and for the fiscal year ended December 31, 2017. The Company pays a commitment fee (0.12% as of December 31, 2017) based on the unused portion of the facility and interest equal to a Base Rate or Eurocurrency Rate plus a spread on borrowings under the facility. The Base Rate is determined based on either the Federal Funds Rate plus a spread, Prime Rate or Eurocurrency Rate plus a spread. The commitment fee and the amount of the spread to the Base Rate or Eurocurrency Rate both vary based on the Company's long-term debt ratings and the Company's leverage. At December 31, 2017, the interest rate under the facility was equal to Eurocurrency Rate plus 1.125%. The Company has an agreement with a group of banks providing a commercial paper program (the “Program”). Under the Program, at the Company’s request the banks may either purchase from the Company, or arrange for the sale by the Company of, unsecured commercial paper notes. Borrowings under the Program are supported by the aforementioned unsecured committed line of credit and the Company may issue notes from time to time up to an aggregate principal amount outstanding at any given time of $1,000,000 which was increased from $700,000 in December 2017. The maturities of the notes may vary but may not exceed 397 days. Subject to market conditions, the notes will be sold under customary terms in the commercial paper market and will be issued at a discount to par, or alternatively, will be sold at par and will bear varying interest rates based on a fixed or floating rate basis. The interest rates will vary based on market conditions and the ratings assigned to the notes by the credit rating agencies at the time of issuance. At December 31, 2017, the Company had notes outstanding under the Program of $137,500 with a weighted average interest rate of 1.85%. At December 25, 2016, the Company had notes outstanding under the Program of $163,300 with a weighted average interest rate of 0.97%.
