Employee Benefit Plans

Employee Benefit Plans

Defined Contribution Plan—The Company sponsors employee 401(k) savings plans for its employees, including certain union employees. The plans provide for various required and discretionary Company matches of employees’ eligible compensation contributed to the plans. The expense for the defined contribution plans was $12.1 million, $11.7 million and $11.2 million for the years ended January 2, 2021, December 28, 2019 and December 29, 2018, respectively.

Defined Benefit and Other Postretirement Benefits Plans—The Company’s subsidiary, Continental Cement, sponsors two noncontributory defined benefit pension plans for hourly and salaried employees. The plans are closed to new participants and benefits are frozen. As a result of the collective bargaining unit negotiations in 2017, the hourly defined benefit pension

plan was amended to stop future benefit accruals for the Davenport employees effective December 31, 2017. Pension benefits for eligible hourly employees are based on a monthly pension factor for each year of credited service. Pension benefits for eligible salaried employees are generally based on years of service and average eligible compensation.

Continental Cement also sponsors two unfunded healthcare and life insurance benefits plans for certain eligible retired employees. Effective January 1, 2014, the plan covering employees of the Hannibal, Missouri location was amended to eliminate all future retiree health and life coverage for current employees. During 2015, Continental Cement adopted one new unfunded healthcare plan to provide benefits prior to Medicare eligibility for certain hourly employees of the Davenport, Iowa location. As a result of the collective bargaining unit negotiations in 2017, hourly Davenport employees hired on or after January 1, 2018 are no longer eligible for retiree medical benefits.

The funded status of the pension and other postretirement benefit plans is recognized in the consolidated balance sheets as the difference between the fair value of plan assets and the benefit obligations. For defined benefit pension plans, the benefit obligation is the projected benefit obligation (“PBO”) and for the healthcare and life insurance benefits plans, the benefit obligation is the accumulated postretirement benefit obligation (“APBO”). The PBO represents the actuarial present value of benefits expected to be paid upon retirement based on estimated future compensation levels. However, since the plans’ participants are not subject to future compensation increases, the plans’ PBO equals the accumulated benefit obligation (“ABO”). The APBO represents the actuarial present value of postretirement benefits attributed to employee services already rendered. The fair value of plan assets represents the current market value of assets held by an irrevocable trust fund for the sole benefit of participants. The measurement of the benefit obligations is based on the Company’s estimates and actuarial valuations. These valuations reflect the terms of the plan and use participant-specific information, such as compensation, age and years of service, as well as certain assumptions that require significant judgment, including estimates of discount rates, expected return on plan assets, rate of compensation increases, interest-crediting rates and mortality rates.

The Company uses December 31 as the measurement date for its defined benefit pension and other postretirement benefit plans.

Obligations and Funded Status—The following information is as of January 2, 2021 and December 28, 2019 and for the years ended January 2, 2021, December 28, 2019 and December 29, 2018:

Assumptions—Weighted-average assumptions used to determine the benefit obligations as of year-end 2020 and 2019 are:

	2020		2019
		Healthcare		Healthcare
	Pension benefits	& Life Ins.	Pension benefits	& Life Ins.
Discount rate	1.84% - 2.14%	1.80% - 1.82%	2.78% - 2.96%	2.73% - 2.79%
Expected long-term rate of return on plan assets	7.00%	N/A	7.00%	N/A

Weighted-average assumptions used to determine net periodic benefit cost for years ended January 2, 2021, December 28, 2019 and December 29, 2018:

	2020		2019		2018
		Healthcare		Healthcare		Healthcare
	Pension benefits	& Life Ins.	Pension benefits	& Life Ins.	Pension benefits	& Life Ins.
Discount rate	2.78% - 2.96%	2.73% - 2.79%	3.90% - 4.02%	3.87% - 3.91%	3.23% - 3.37%	3.20% - 3.25%
Expected long-term rate of return on plan assets	7.00%	N/A	7.00%	N/A	7.00%	N/A

The expected long-term return on plan assets is based upon the Plans’ consideration of historical and forward-looking returns and the Company’s estimation of what a portfolio, with the target allocation described below, will earn over a long-term horizon. The discount rate is derived using the FTSE Pension Discount Curve.

Assumed health care cost trend rates were 8.0% as of year-end 2020 and 2019, grading to an ultimate trend rate of 4.5% in 2034 and 2033. Assumed health care cost trend rates have a significant effect on the amounts reported for the Company’s healthcare and life insurance benefits plans.

Plan Assets—The defined benefit pension plans’ (the “Plans”) investment strategy is to minimize investment risk while generating acceptable returns. The Plans currently invest a relatively high proportion of the plan assets in fixed income securities, while the remainder is invested in equity securities, cash reserves and precious metals. The equity securities are diversified into funds with growth and value investment strategies. The target allocation for plan assets is as follows: equity securities—30%; fixed income securities—63%; cash reserves—5%; and precious metals—2%. The Plans’ current investment allocations are within the tolerance of the target allocation. The Company had no Level 3 investments as of or for the years ended January 2, 2021 and December 28, 2019.

At year-end 2020 and 2019, the Plans’ assets were invested predominantly in fixed-income securities and publicly traded equities, but may invest in other asset classes in the future subject to the parameters of the investment policy. The Plans’ investments in fixed-income assets include U.S. Treasury and U.S. agency securities and corporate bonds. The Plans’ investments in equity assets include U.S. and international securities and equity funds. The Company estimates the fair value of the Plans’ assets using various valuation techniques and, to the extent available, quoted market prices in active markets or observable market inputs. The descriptions and fair value methodologies for the Plans’ assets are as follows:

Fixed Income Securities—Corporate and government bonds are classified as Level 2 assets, as they are either valued at quoted market prices from observable pricing sources at the reporting date or valued based upon comparable securities with similar yields and credit ratings.

Equity Securities—Equity securities are valued at the closing market price reported on a U.S. exchange where the security is actively traded and are therefore classified as Level 1 assets.

Cash—The carrying amounts of cash approximate fair value due to the short-term maturity.

Precious Metals—Precious metals are valued at the closing market price reported on a U.S. exchange where the security is actively traded and are therefore classified as Level 1 assets.

The fair value of the Plans’ assets by asset class and fair value hierarchy level as of January 2, 2021 and December 28, 2019 are as follows:

Cash Flows—The Company expects to contribute approximately $1.2 million and $0.6 million in 2021 to its pension plans and to its healthcare and life insurance benefits plans, respectively.

The estimated benefit payments for each of the next five years and the five-year period thereafter are as follows:

	Pension		Healthcare and Life
	benefits		Insurance Benefits
2021	$	1,692	$	636
2022	1,693		630
2023	1,696		617
2024	1,655		619
2025	1,613		627
2026 - 2030	7,597		3,139

Multiemployer Pension Plans— In 2018, the Company acquired Buildex, LLC and assumed its obligation to contribute to a number of multiemployer defined benefit pension plans under the terms of collective-bargaining agreements that cover its union-represented employees. The risks of participating in multiemployer pension plans are different from single-employer plans. Assets contributed to a multiemployer plan by one employer may be used to provide benefits to employees of other participating employers. If a participating employer ceases contributing to the plan, the unfunded obligations of the plan are the responsibility of the remaining participating employers.

The Company's participation in these plans for the annual period ended December 31, 2020, is outlined in the table below. The ''EIN/Pension Plan Number" column provides the Employer Identification Number (EIN) and the three-digit plan number, if applicable. Unless otherwise noted, the most recent Pension Protection Act (PPA) zone status available in 2020 and 2019 is for the plan 's year end at December 31, 2020, and December 31, 2019, respectively. The zone status is based on information the Company received from the plan and is certified by the plan's actuary. Among other factors, plans in the red zone are generally less than 65% funded, plans in the yellow zone are less than 80% funded and plans in the green zone are at least 80% funded. The "FIP/RP Status Pending/Implemented" column indicates plans for which a financial improvement plan (FIP) or a rehabilitation plan (RP) is either pending or has been implemented. The "Surcharge Imposed" column indicates whether a surcharge has been imposed on contributions to the plan. The last column lists the expiration date(s) of the collective-bargaining agreement(s) to which the plans are subject. There have been no significant changes that affect the comparability of 2020 and 2019 contributions.

										Expiration Date of

Employee Benefit Plans

Defined Contribution Plan—The Company sponsors employee 401(k) savings plans for its employees, including certain union employees. The plans provide for various required and discretionary Company matches of employees’ eligible compensation contributed to the plans. The expense for the defined contribution plans was $12.1 million, $11.7 million and $11.2 million for the years ended January 2, 2021, December 28, 2019 and December 29, 2018, respectively.

Defined Benefit and Other Postretirement Benefits Plans—The Company’s subsidiary, Continental Cement, sponsors two noncontributory defined benefit pension plans for hourly and salaried employees. The plans are closed to new participants and benefits are frozen. As a result of the collective bargaining unit negotiations in 2017, the hourly defined benefit pension plan was amended to stop future benefit accruals for the Davenport employees effective December 31, 2017. Pension benefits for eligible hourly employees are based on a monthly pension factor for each year of credited service. Pension benefits for eligible salaried employees are generally based on years of service and average eligible compensation.

Continental Cement also sponsors two unfunded healthcare and life insurance benefits plans for certain eligible retired employees. Effective January 1, 2014, the plan covering employees of the Hannibal, Missouri location was amended to eliminate all future retiree health and life coverage for current employees.

As a result of the collective bargaining unit negotiations in 2017, hourly Davenport employees hired on or after January 1, 2018 are no longer eligible for retiree medical benefits.

The funded status of the pension and other postretirement benefit plans is recognized in the consolidated balance sheets as the difference between the fair value of plan assets and the benefit obligations. For defined benefit pension plans, the benefit obligation is the projected benefit obligation (“PBO”) and for the healthcare and life insurance benefits plans, the benefit obligation is the accumulated postretirement benefit obligation (“APBO”). The PBO represents the actuarial present value of benefits expected to be paid upon retirement based on estimated future compensation levels. However, since the plans’ participants are not subject to future compensation increases, the plans’ PBO equals the accumulated benefit obligation (“ABO”). The APBO represents the actuarial present value of postretirement benefits attributed to employee services already rendered. The fair value of plan assets represents the current market value of assets held by an irrevocable trust fund for the sole benefit of participants. The measurement of the benefit obligations is based on the Company’s estimates and actuarial valuations. These valuations reflect the terms of the plan and use participant-specific information, such as compensation, age and years of service, as well as certain assumptions that require significant judgment, including estimates of discount rates, expected return on plan assets, rate of compensation increases, interest-crediting rates and mortality rates.

The Company uses December 31 as the measurement date for its defined benefit pension and other postretirement benefit plans.

Obligations and Funded Status—The following information is as of January 2, 2021 and December 28, 2019 and for the years ended January 2, 2021, December 28, 2019 and December 29, 2018:

Weighted-average assumptions used to determine net periodic benefit cost for years ended January 2, 2021, December 28, 2019 and December 29, 2018:

	2020		2019		2018
		Healthcare		Healthcare		Healthcare
	Pension benefits	& Life Ins.	Pension benefits	& Life Ins.	Pension benefits	& Life Ins.

Expected long-term rate of return on plan assets	7.00%	N/A	7.00%	N/A	7.00%	N/A

The expected long-term return on plan assets is based upon the Plans’ consideration of historical and forward-looking returns and the Company’s estimation of what a portfolio, with the target allocation described below, will earn over a long-term horizon. The discount rate is derived using the FTSE Pension Discount Curve.

Assumed health care cost trend rates were 8.0% as of year-end 2020 and 2019, grading to an ultimate trend rate of 4.5% in 2034 and 2033. Assumed health care cost trend rates have a significant effect on the amounts reported for the Company’s healthcare and life insurance benefits plans.

Plan Assets—The defined benefit pension plans’ (the “Plans”) investment strategy is to minimize investment risk while generating acceptable returns. The Plans currently invest a relatively high proportion of the plan assets in fixed income securities, while the remainder is invested in equity securities, cash reserves and precious metals. The equity securities are diversified into funds with growth and value investment strategies. The target allocation for plan assets is as follows: equity securities—30%; fixed income securities—63%; cash reserves—5%; and precious metals—2%. The Plans’ current investment allocations are within the tolerance of the target allocation. The Company had no Level 3 investments as of or for the years ended January 2, 2021 and December 28, 2019.

At year-end 2020 and 2019, the Plans’ assets were invested predominantly in fixed-income securities and publicly traded equities, but may invest in other asset classes in the future subject to the parameters of the investment policy. The Plans’ investments in fixed-income assets include U.S. Treasury and U.S. agency securities and corporate bonds. The Plans’ investments in equity assets include U.S. and international securities and equity funds. The Company estimates the fair value of the Plans’ assets using various valuation techniques and, to the extent available, quoted market prices in active markets or observable market inputs. The descriptions and fair value methodologies for the Plans’ assets are as follows:

Fixed Income Securities—Corporate and government bonds are classified as Level 2 assets, as they are either valued at quoted market prices from observable pricing sources at the reporting date or valued based upon comparable securities with similar yields and credit ratings.

Equity Securities—Equity securities are valued at the closing market price reported on a U.S. exchange where the security is actively traded and are therefore classified as Level 1 assets.

Cash—The carrying amounts of cash approximate fair value due to the short-term maturity.

Precious Metals—Precious metals are valued at the closing market price reported on a U.S. exchange where the security is actively traded and are therefore classified as Level 1 assets.

The fair value of the Plans’ assets by asset class and fair value hierarchy level as of January 2, 2021 and December 28, 2019 are as follows:

Multiemployer Pension Plans— In 2018, the Company acquired Buildex, LLC and assumed its obligation to contribute to a number of multiemployer defined benefit pension plans under the terms of collective-bargaining agreements that cover its union-represented employees. The risks of participating in multiemployer pension plans are different from single-employer plans. Assets contributed to a multiemployer plan by one employer may be used to provide benefits to employees of other participating employers. If a participating employer ceases contributing to the plan, the unfunded obligations of the plan are the responsibility of the remaining participating employers.

The Company's participation in these plans for the annual period ended December 31, 2020, is outlined in the table below. The ''EIN/Pension Plan Number" column provides the Employer Identification Number (EIN) and the three-digit plan number, if applicable. Unless otherwise noted, the most recent Pension Protection Act (PPA) zone status available in 2020 and 2019 is for the plan 's year end at December 31, 2020, and December 31, 2019, respectively. The zone status is based on information the Company received from the plan and is certified by the plan's actuary. Among other factors, plans in the red zone are generally less than 65% funded, plans in the yellow zone are less than 80% funded and plans in the green zone are at least 80% funded. The "FIP/RP Status Pending/Implemented" column indicates plans for which a financial improvement plan (FIP) or a rehabilitation plan (RP) is either pending or has been implemented. The "Surcharge Imposed" column indicates whether a surcharge has been imposed on contributions to the plan. The last column lists the expiration date(s) of the collective-bargaining agreement(s) to which the plans are subject. There have been no significant changes that affect the comparability of 2020 and 2019 contributions.
