Defined Benefit Plans

The Company sponsors a number of defined benefit retirement plans covering certain of its U.S. employees and non-U.S. employees. As of December 27, 2024 (Successor), U.S. plans represented 33.1% of the Company's remaining projected benefit obligation. The Company generally does not provide postretirement benefits other than retirement plan benefits for its employees; however, certain of the Company's U.S. employees participate in postretirement benefit plans that provide medical benefits. These plans are unfunded.

The benefit obligation recognized on the consolidated balance sheets were $17.0 million and $18.9 million as of December 27, 2024 (Successor) and December 29, 2023 (Successor), respectively, for pension benefits and $12.5 million and $25.9 million as of December 27, 2024 (Successor) and December 29, 2023 (Successor), respectively, for postretirement benefits. The weighted-average discount rate to determine benefit obligations for the Company's pension and postretirement benefit plans ranged from 3.4% to 5.5%. For the Company's unfunded U.S. plans, the discount rate is based on the market rate for a broad population of AA-rated (Moody's Investor Services, Inc. or Standard & Poor's Corporation) corporate bonds over $250.0 million.

Defined Contribution Retirement Plans

The Company maintains one active tax-qualified 401(k) retirement plan and one active non-qualified deferred compensation plan in the U.S. The 401(k) retirement plan provides for an automatic Company contribution of 3% of an eligible employee's pay, with an additional Company matching contribution generally equal to 50.0% of each employee's elective contribution to the plan up to 8% of the employee's eligible pay. The deferred compensation plan permitted eligible employees to defer a portion of their compensation. The deferred compensation plan is currently frozen for employee deferrals. Total defined contribution expense was $23.0 million, $2.5 million, $18.6 million, $7.8 million, and $9.6 million for the year ended December 27, 2024 (Successor), the period November 15, 2023 through December 29, 2023 (Successor), the period December 31, 2022 through November 14, 2023 (Predecessor), the period June 17, 2022 through December 30, 2022 (Predecessor), and the period January 1, 2022 through June 16, 2022 (Predecessor), respectively.

Rabbi Trusts and Other Investments

The Company maintains several rabbi trusts, the assets of which are used to pay retirement benefits. The rabbi trust assets are subject to the claims of the Company's creditors in the event of the Company's insolvency. Plan participants are general creditors of the Company with respect to these benefits. The trusts primarily hold life insurance policies and debt and equity securities, the value of which is included in other assets on the consolidated balance sheets. See Note 20 for additional information regarding the debt and equity securities.

The carrying value of the 37 and 48 life insurance contracts held by these trusts was $37.2 million and $38.0 million as of December 27, 2024 (Successor) and December 29, 2023 (Successor), respectively. These contracts had a total death benefit of $66.7 million and $74.2 million as of December 27, 2024 (Successor) and December 29, 2023 (Successor), respectively. However, there are outstanding loans against the policies amounting to $13.2 million and $18.3 million as of December 27, 2024 (Successor) and December 29, 2023 (Successor), respectively. During the year ended December 27, 2024 (Successor), proceeds from debt and equity securities held in rabbi trusts were $22.6 million.

The Company has insurance contracts that serve as collateral for certain of the Company's non-U.S. pension plan benefits. These insurance contracts totaled $6.5 million and $7.3 million as of December 27, 2024 (Successor) and December 29, 2023 (Successor), respectively. These amounts were included in other assets on the consolidated balance sheets.
