PENSION AND POSTRETIREMENT BENEFITS

18. PENSION AND POSTRETIREMENT BENEFITS

We have defined benefit retirement plans ("pension plans") for eligible salaried and hourly employees. Benefits are based on years of credited service and average compensation or stated amounts for each year of service. We also sponsor postretirement plans which provide certain medical and dental benefits to qualifying U.S. employees. Effective August 1, 2013, our defined benefit pension plan for eligible salaried employees was closed to new hire salaried employees. New hire salaried employees will generally be eligible to participate in our defined contribution plan.

During the third quarter of fiscal 2020, we amended a certain hourly pension plan that froze future compensation and service periods. As a result, we remeasured the Company's hourly pension plan liability as of January 31, 2020 and recorded a pension curtailment loss of $0.2 million previously within other comprehensive income (loss). In connection with the remeasurement, we updated the effective discount rate assumption for the impacted pension plan from 3.86% to 2.96%. The remeasurement increased the underfunded status of the pension plan by $4.3 million with a corresponding loss within other comprehensive income (loss).

During the second quarter of fiscal 2020, the Company provided a voluntary lump-sum settlement offer to certain terminated vested participants in the salaried pension plan in order to reduce a portion of the pension obligation. During the third quarter of fiscal 2020, lump-sum settlement payments totaling $154.6 million were distributed from pension plan assets to such participants. As a result of the settlement, we were required to remeasure our pension plan liability. In connection with the remeasurement, we updated the effective discount rate assumption for the impacted pension plan obligation from 3.89% to 3.37%, as of December 31, 2019. The settlement and related remeasurement resulted in the recognition of a settlement gain of $2.1 million, reflected in pension and postretirement non-service income, as well as a benefit to other comprehensive income (loss) totaling $79.8 million in the third quarter of fiscal 2020.

As a result of the anticipated exit of certain facilities, during the first quarter of fiscal 2020, we remeasured the Company's hourly pension plan as of August 25, 2019 and recorded a pension curtailment loss of $0.6 million previously within other comprehensive income (loss). In connection with the remeasurement, we updated the effective discount rate assumption for the impacted pension plan obligation from 3.90% to 3.13%. The curtailment loss and related remeasurement increased the underfunded status of the pension plan by $12.3 million with a corresponding loss within other comprehensive income (loss).

We recognize the funded status of our pension and postretirement plans in the Consolidated Balance Sheets. For our pension plans, we also recognize as a component of accumulated other comprehensive income (loss), the net of tax results of the actuarial gains or losses within the corridor and prior service costs or credits that arise during the period but are not recognized in net periodic benefit cost. For our postretirement plans, we also recognize as a component of accumulated other comprehensive income (loss), the net of tax results of the gains or losses and prior service costs or credits that arise during the period but are not recognized in net periodic benefit cost. These amounts will be adjusted out of accumulated other comprehensive income (loss) as they are subsequently recognized as components of net periodic benefit cost. For our pension plans, we have elected to immediately recognize actuarial gains and losses in our operating results in the year in which they occur, to the extent they exceed the corridor, eliminating amortization. Amounts are included in the components of pension and postretirement plan costs, below, as recognized net actuarial loss.

The changes in benefit obligations and plan assets at May 30, 2021 and May 31, 2020 are presented in the following table.

The accumulated benefit obligation for all defined benefit pension plans was $3.74 billion and $3.87 billion at May 30, 2021 and May 31, 2020, respectively.

The projected benefit obligation, accumulated benefit obligation, and fair value of plan assets for pension plans with accumulated benefit obligations in excess of plan assets at May 30, 2021 and May 31, 2020 were:

	2021		2020
Projected benefit obligation	$	135.4	$	1,062.8
Accumulated benefit obligation		135.4		1,062.8
Fair value of plan assets		—		808.2

In fiscal 2021, 2020, and 2019, the Company recorded charges of $0.8 million, $44.8 million, and $5.1 million, respectively, reflecting the year-end write-off of actuarial losses in excess of 10% of our pension liability. In fiscal 2020, the higher actuarial losses outside of the 10% corridor were principally related to a reduction in the discount rate used to recognize at present value our pension obligations and a decline in market value of certain plan assets associated with our non-qualified and hourly plans.

Other changes in plan assets and benefit obligations recognized in other comprehensive income (loss) were:

	Pension Plans						Postretirement Plans
	2021			2020			2021			2020
Net actuarial gain (loss)	$	92.0		$	21.9		$	2.5		$	(2.9	)

Long-term rate of compensation increase	N/A			N/A				3.63	%	N/A			N/A			N/A

The Company uses a split discount rate (spot-rate approach) for the U.S. plans and certain foreign plans. The spot-rate approach applies separate discount rates for each projected benefit payment in the calculation of pension service and interest cost.

We amortize prior service cost for our pension and postretirement plans, as well as amortizable gains and losses for our postretirement plans, in equal annual amounts over the average expected future period of vested service. For plans with no active participants, average life expectancy is used instead of average expected useful service.

Plan Assets

The fair value of plan assets, summarized by level within the fair value hierarchy described in Note 19, as of May 30, 2021, was as follows:

	Level 1		Level 2		Level 3		Total
Cash and cash equivalents	$	7.5	$	85.0	$	—	$	92.5
Equity securities:
U.S. equity securities		78.0		94.6		—		172.6

The fair value of plan assets, summarized by level within the fair value hierarchy described in Note 19, as of May 31, 2020, was as follows:

	Level 1		Level 2		Level 3		Total
Cash and cash equivalents	$	10.1	$	71.9	$	—	$	82.0

Investments measured at net asset value								241.0
Total pension plan assets							$	3,820.4

Level 1 assets are valued based on quoted prices in active markets for identical securities. The majority of the Level 1 assets listed above include the common stock of both U.S. and international companies, mutual funds, master limited partnership units, and real estate investment trusts, all of which are actively traded and priced in the market.

Level 2 assets are valued based on other significant observable inputs including quoted prices for similar securities, yield curves, indices, etc. Level 2 assets consist primarily of individual fixed income securities where values are based on quoted prices of similar securities and observable market data.

Level 3 assets consist of investments where active market pricing is not readily available and, as such, fair value is estimated using significant unobservable inputs.

Certain assets that are measured at fair value using the NAV (net asset value) per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. Such investments are generally considered long-term in nature with varying redemption availability. For certain of these investments, with a fair value of approximately $52.2 million as of May 30, 2021, the asset managers have the ability to impose customary redemption gates which may further restrict or limit the redemption of invested funds therein. As of May 30, 2021, no such gates were imposed.

As of May 30, 2021, we have unfunded commitments for additional investments of $32.6 million in private equity funds and $10.9 million in natural resources funds. We expect unfunded commitments to be funded from plan assets rather than the general assets of the Company.

To develop the expected long-term rate of return on plan assets assumption for the pension plans, we consider the current asset allocation strategy, the historical investment performance, and the expectations for future returns of each asset class.

Our pension plan weighted-average asset allocations by asset category were as follows:

	May 30, 2021			May 31, 2020
Equity securities		8	%		6	%
Debt securities		83	%		85	%
Real estate funds		1	%		1	%
Private equity		3	%		3	%
Other		5	%		5	%
Total		100	%		100	%

Due to the salaried pension plan freeze that occurred in fiscal 2018, the Company's pension asset strategy is now designed to align our pension plan assets with our projected benefit obligation to reduce volatility by targeting an investment strategy of approximately 90% in fixed-income securities and approximately 10% in return seeking assets, primarily equity securities, real estate, and private assets.

Assumed health care cost trend rates have a significant effect on the benefit obligation of the postretirement plans.

Assumed Health Care Cost Trend Rates at:	May 30, 2021			May 31, 2020
Initial health care cost trend rate		6.53	%		6.22	%
Ultimate health care cost trend rate		4.44	%		4.43	%
Year that the rate reaches the ultimate trend rate	2029			2024

We currently anticipate making contributions of approximately $12.3 million to our pension plans in fiscal 2022. We anticipate making contributions of $9.0 million to our other postretirement plans in fiscal 2022. These estimates are based on ERISA guidelines, current tax laws, plan asset performance, and liability assumptions, which are subject to change.

The following table presents estimated future gross benefit payments for our plans:

	Pension Plans		Postretirement Plans
2022	$	201.6	$	9.1
2023		203.0		8.4
2024		204.7		7.7
2025		206.1		7.1
2026		207.3		6.5
Succeeding 5 years		1,031.1		25.2

Multiemployer Pension Plans

The Company contributes to several multiemployer defined benefit pension plans under collective bargaining agreements that cover certain units of its union-represented employees. The risks of participating in such plans are different from the risks of single-employer plans, in the following respects:

a. Assets contributed to a multiemployer plan by one employer may be used to provide benefits to employees of other participating employers.

b. If a participating employer ceases to contribute to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers.

c. If the Company ceases to have an obligation to contribute to a multiemployer plan in which it had been a contributing employer, it may be required to pay to the plan an amount based on the underfunded status of the plan and on the history of the Company's participation in the plan prior to the cessation of its obligation to contribute. The amount that an employer that has ceased to have an obligation to contribute to a multiemployer plan is required to pay to the plan is referred to as a withdrawal liability.

The Company's participation in multiemployer plans for the fiscal year ended May 30, 2021 is outlined in the table below. For each plan that is individually significant to the Company the following information is provided:

• The "EIN / PN" column provides the Employer Identification Number and the three-digit plan number assigned to a plan by the Internal Revenue Service.

• The most recent Pension Protection Act Zone Status available for 2020 and 2019 is for plan years that ended in calendar years 2020 and 2019, respectively. The zone status is based on information provided to the Company by each plan. A plan in the "red" zone has been determined to be in "critical status", based on criteria established under the Internal Revenue Code ("Code"), and is generally less than 65% funded. A plan in the "yellow" zone has been determined to be in "endangered status", based on criteria established under the Code, and is generally less than 80% funded. A plan in the "green" zone has been determined to be neither in "critical status" nor in "endangered status", and is generally at least 80% funded.

• The "FIP/RP Status Pending/Implemented" column indicates whether a Funding Improvement Plan, as required under the Code to be adopted by plans in the "yellow" zone, or a Rehabilitation Plan, as required under the Code to be adopted by plans in the "red" zone, is pending or has been implemented by the plan as of the end of the plan year that ended in calendar year 2020.

• Contributions by the Company are the amounts contributed in the Company's fiscal periods ending in the specified year.

• The "Surcharge Imposed" column indicates whether the Company contribution rate for its fiscal year that ended on May 30, 2021 included an amount in addition to the contribution rate specified in the applicable collective bargaining agreement, as imposed by a plan in "critical status", in accordance with the requirements of the Code.

• The last column lists the expiration dates of the collective bargaining agreements pursuant to which the Company contributes to the plans.

For plans that are not individually significant to Conagra Brands the total amount of contributions is presented in the aggregate.

The Company was not listed in the Forms 5500 filed by any of the other plans or for any of the other years as providing more than 5% of the plan's total contributions. At the date our financial statements were issued, Forms 5500 were not available for plan years ending in calendar year 2020.

During fiscal 2019, we ceased to participate in the Bakery and Confectionary Union and Industry International Fund in conjunction with our sale of the Trenton, Missouri plant.

In addition to the contributions listed in the table above, we recorded an additional expense of $0.3 million in fiscal 2019 related to our expected incurrence of certain withdrawal costs.

Certain of our employees are covered under defined contribution plans. The expense related to these plans was $47.6 million, $49.9 million, and $39.9 million in fiscal 2021, 2020, and 2019, respectively.
