Table of Contents The Company incurred expense for contributions under its defined contribution plans of $6, $7, $17 and $16 during the periods July 2, 2019 through December 31, 2019, January 1, 2019 through July 1, 2019 and the years ended December 31, 2018 and 2017, respectively. The Company provides key executives in some locations with non-qualified benefit plans that provide participants with an opportunity to elect to defer compensation or to otherwise provide supplemental retirement benefits in cases where executives cannot fully participate in the defined benefit or defined contribution plans because of plan or local statutory limitations. Most of the Company's supplemental benefit plans are unfunded and benefits are paid from the general assets of the Company. The liabilities related to defined benefit supplemental benefits are included in the previously discussed defined benefit pension disclosures. The Company maintains a non-qualified defined contribution plan (the “SERP”) that provides annual employer credits to eligible U.S. associates of 5% of eligible compensation above the IRS limit for qualified plans. The Company can also make discretionary credits under the SERP; however, no participant contributions are permitted. The account credits are made annually to an unfunded phantom account, in the following calendar year. Certain executives also previously earned benefits under U.S. non-qualified executive supplemental plans that were frozen prior to 2010. The Company’s liability for these non-qualified benefit plans was $5 and $5 at December 31, 2019 and 2018, and is included in “Other long-term liabilities” in the Consolidated Balance Sheets. The Company’s German subsidiaries offer a government subsidized early retirement program to eligible associates called Altersteilzeit or ATZ Plans. The German government provides a subsidy in certain cases where the participant is replaced with a qualifying candidate. The Company had liabilities for these arrangements of $2 and $1 at December 31, 2019 and 2018, respectively. The Company incurred expense for these plans of less than $1 for the periods July 2, 2019 through December 31, 2019, January 1, 2019 through July 1, 2019 and the years ended December 31, 2018 and 2017, respectively. Also included in the Consolidated Balance Sheets at December 31, 2019 and 2018 are other post-employment benefit obligations relating to long-term disability and for liabilities relating to European jubilee benefit plans of $4 and $4, respectively.
