Compensation and Retirement Disclosure [Abstract]
Pension and Other Postretirement Benefits Disclosure [Text Block]	Retirement Benefit Plans 401(k) Plan Subject to certain restrictions, the Company has a 401(k) defined contribution plan (the “401(k) Plan”) for all of its employees who meet certain minimum requirements and elect to participate. The 401(k) Plan permits employees to contribute up to 75% of their compensation, subject to certain limitations and provides for matching employee contributions up to 4% of compensation and for discretionary profit sharing contributions. In connection with the matching and profit sharing contributions, the Company recognized compensation expense of $5,177, $6,124 and $6,550 in 2016, 2015 and 2014, respectively. Pension Plans The Wendy’s Company maintains two domestic qualified defined benefit plans, the benefits under which were frozen in 1988 and for which The Wendy’s Company has no unrecognized prior service cost. Arby’s employees who were eligible to participate through 1988 (the “Eligible Arby’s Employees”) are covered under one of these plans. Pursuant to the terms of the Arby’s sale agreement, Wendy’s Restaurants retained the liabilities related to the Eligible Arby’s Employees under these plans and received $400 from the buyer for the unfunded liability related to the Eligible Arby’s Employees. In conjunction with the sale of Arby’s, Wendy’s Restaurants transferred the liabilities related to the Eligible Arby’s Employees to The Wendy’s Company. The measurement date used by The Wendy’s Company in determining amounts related to its defined benefit plans is the same as the Company’s fiscal year end. The balance of the accumulated benefit obligations and the fair value of the plans’ assets at January 1, 2017 were $3,609 and $2,641, respectively. As of January 3, 2016, the balance of the accumulated benefit obligations and the fair value of the plans’ assets were $3,809 and $2,699, respectively. As of January 1, 2017 and January 3, 2016, each of the plans had accumulated benefit obligations in excess of the fair value of the assets of the respective plan. The Wendy’s Company recognized $177, $149, and $126 in benefit plan expenses in 2016, 2015 and 2014, respectively, which were included in “General and administrative.” The Wendy’s Company’s future required contributions to the plan are expected to be insignificant. Multiemployer Pension Plan Prior to the fourth quarter of 2013, the unionized employees at The New Bakery Co. of Ohio, Inc. (the “Bakery Company”), a 100% owned subsidiary of Wendy’s, now known as The Bakery Company, LLC, were covered by the Bakery and Confectionery Union and Industry International Pension Fund (the “Union Pension Fund”), a multiemployer pension plan. The Bakery Company remitted contributions based on hours worked by covered, unionized employees pursuant to a collective bargaining agreement that expired on March 31, 2013 and the Rehabilitation Plan adopted by the Union Pension Fund in accordance with the provisions of the Pension Protection Act of 2006 due to the underfunded status of the plan. In December of 2013, the Bakery Company terminated its participation in the Union Pension Fund and formally notified the plan’s trustees of its withdrawal from the plan. The Union Pension Fund administrator acknowledged the withdrawal, which required Wendy’s to assume an estimated withdrawal liability of $13,500 based on the applicable requirements of the Employee Retirement Income Security Act, as amended, and which was included in “Cost of sales” during the fourth quarter of 2013. As a result, Wendy’s made payments to the Union Pension Fund aggregating $1,014 during 2014 and 2015 which were recorded as reductions to the withdrawal liability. The Bakers Local No. 57, Bakery, Confectionery, Tobacco Workers & Grain Millers International Union of America, AFL-CIO (the “Union”) filed a charge with the National Labor Relations Board (the “NLRB”) related to the Bakery Company’s withdrawal from the Union Pension Fund. On July 22, 2014, The New Bakery of Zanesville, LLC (“Zanesville”), a 100% owned subsidiary of Wendy’s, and the Union entered into a settlement agreement with the NLRB. The terms of the settlement include an agreement by Zanesville and the Union to recommence negotiations. On March 27, 2015, Zanesville and the Union signed a memorandum of agreement outlining the terms for a new collective bargaining agreement, including re-entering the Union Pension Fund and signing the collective bargaining agreement on or about May 15, 2015. The terms of the collective bargaining agreement were ratified by the Union and became effective upon execution of the collective bargaining agreement. During the first quarter of 2015, the Company began negotiating the potential sale of the Bakery Company which would result in the buyer signing the collective bargaining agreement and re-entering the Union Pension Fund. As a result, the Company concluded that its loss contingency for the pension withdrawal payments was no longer probable and, as such, reversed $12,486 of the outstanding withdrawal liability to “Cost of sales” during the first quarter of 2015. During the second quarter of 2015, with negotiations ongoing, Zanesville and the Union agreed to an extension of the May 15, 2015 deadline for re-entering the Union Pension Fund. On May 15, 2015, in preparation for the sale of the Bakery, Zanesville merged into the Bakery Company. The Bakery Company was sold on May 31, 2015 and subsequently the Bakery Company signed the collective bargaining agreement and re-entered the Union Pension Fund. As a result of the sale of its membership interest in the Bakery Company, Wendy’s no longer has any obligations related to the Union Pension Fund. The unionized employees were eligible to participate in the 401(k) Plan from December 5, 2013 through May 31, 2015, for which the Company has made contributions. As a result of the sale of the Bakery, the amounts described above have been included in “Net income from discontinued operations.” See Note 18 for more information on the sale of the Bakery. Wendy’s Executive Plans In conjunction with the Wendy’s merger, amounts due under supplemental executive retirement plans (the “SERP”) were funded into a restricted account. As of January 1, 2011, participation in the SERP was frozen to new entrants and future contributions, and existing participants’ balances only earn annual interest. The corresponding SERP liabilities have been included in “Accrued expenses and other current liabilities” and “Other liabilities” and, in the aggregate, were approximately $3,101 and $3,396 as of January 1, 2017 and January 3, 2016, respectively. Pursuant to the terms of the employment agreement that was entered into with our then Chief Executive Officer as of September 12, 2011, the Company implemented a non-qualified, unfunded, deferred compensation plan. The plan provided that the amount of the executive’s base salary in excess of $1,000 in a tax year will be deferred into the plan which accrues employer funded interest. The compensation deferred under the plan was distributed to our former Chief Executive Officer during 2016. As of January 3, 2016, the deferred compensation liability was included in “Accrued expenses and other current liabilities” and was approximately $524, including both employee contributions and employer funded interest. Effective January 1, 2017, the Company implemented a non-qualified, unfunded deferred compensation plan for management and highly compensated employees, whereby participants may defer all or a portion of their base compensation and certain incentive awards on a pre-tax basis. The Company credits the amounts deferred with earnings based on the investment options selected by the participants. The Company may also make discretionary contributions to the plan.
