We have defined benefit pension plans covering certain of our North American employees. In May 2019, the U.S. qualified pension plan was amended such that all employees who were not participants in the plan as of December 31, 2019, will not become participants after such date. All benefit accruals were frozen as of December 31, 2019 for all plan participants with less than eleven years of service as of December 31, 2019. For participants with more than eleven years of service as of December 31, 2019, benefit accruals will be frozen as of December 31, 2022. Participants will continue to accrue interest at a fixed rate of 6 percent per year.

We also sponsor postretirement medical and life insurance plans, which are available to most of our retired U.S. employees. These plans are contributory and are not funded. The measurement date of the assets and liabilities is the month-end date that is closest to our fiscal year end.

The following tables set forth the plans’ changes in benefit obligations and plan assets, funded status, and amounts recognized in the Consolidated Balance Sheets:

The Canadian qualified pension plan’s assets exceeded its accumulated benefit obligation for both 2020 and 2019. Our non-qualified pension plans have an accumulated benefit obligation in excess of plan assets, as these plans are unfunded. Accordingly, the table below reflects both the U.S. qualified plan and the non-qualified plans for both 2020 and 2019.

The actuarial losses incurred during 2020 were primarily driven from a decrease in discount rates applied against future expected benefit payments and resulted in an increase in the benefit obligation for the pension benefit plans. This was partially offset by higher actual return over expected return on plan assets and liability gains from the U.S. qualified plan.

The following weighted-average assumptions were used to determine the benefit obligations under the plans:

Pension expense is actuarially calculated annually based on data available at the beginning of each year. The expected return on plan assets is determined by multiplying the expected long-term rate of return on assets by the market-related value of plan assets for the U.S. qualified pension plan and market value for the Canadian qualified pension plan. The market-related value of plan assets is a calculated value that recognizes investment gains and losses in fair value related to equities over three or five years, depending on which computation results in a market-related value closer to market value. Market-related value for the U.S. qualified plan was $661 million and $601 million for 2020 and 2019, respectively.

Assumptions used in the calculation of net benefit cost include the discount rate selected and disclosed at the end of the previous year, as well as other assumptions detailed in the table below:

(1)	The U.S qualified pension plan was remeasured during the second quarter of 2018 in connection with the pension litigation. The discount rate used to determine the benefit obligation in 2018 before the remeasurement was 3.7%.

The expected long-term rate of return on invested plan assets is based on the plans’ weighted-average target asset allocation, as well as historical and future expected performance of those assets. The target asset allocation is selected to obtain an investment return that is sufficient to cover the expected benefit payments and to reduce the variability of our future contributions.

The following are the components of net periodic pension benefit cost and net periodic postretirement benefit income.


	Pension Benefits						Postretirement Benefits

Service cost is recognized as a component of SG&A and the remaining pension and postretirement expense components are recognized as part of Other income, net.

Beginning in 2001, new retirees were charged the expected full cost of the medical plan, and then-existing retirees will incur 100 percent of the expected future increases in medical plan costs. Any changes in the health care cost trend rates assumed would not affect the accumulated benefit obligation or net benefit income, since retirees will incur 100 percent of such expected future increases.

We maintain a Supplemental Executive Retirement Plan (“SERP”), which is an unfunded plan that includes provisions for the continuation of medical and dental insurance benefits to certain executive officers and other key employees of the Company (“SERP Medical Plan”). The SERP Medical Plan’s accumulated projected benefit obligation at January 30, 2021 was $12 million. The following initial and ultimate cost trend rate assumptions were used to determine the benefit obligations under the SERP Medical Plan:


	Medical Trend Rate						Dental Trend Rate
	2020		2019		2018		2020		2019		2018
Initial cost trend rate	6.3	%	6.5	%	6.5	%	5.0	%	5.0	%	5.0	%
Ultimate cost trend rate	5.0	%	5.0	%	5.0	%	5.0	%	5.0	%	5.0	%
Year that the ultimate cost trend rate is reached	2025		2025		2025		2020		2020		2019

The following initial and ultimate cost trend rate assumptions were used to determine the net periodic cost under the SERP Medical Plan:


	Medical Trend Rate						Dental Trend Rate
	2020		2019		2018		2020		2019		2018
Initial cost trend rate	6.5	%	6.5	%	7.0	%	5.0	%	5.0	%	5.0	%
Ultimate cost trend rate	5.0	%	5.0	%	5.0	%	5.0	%	5.0	%	5.0	%
Year that the ultimate cost trend rate is reached	2025		2025		2025		2020		2019		2018

The mortality assumption used to value the 2020 U.S. pension obligations was the Pri-2012 mortality table with generational projection using MP-2020 for both males and females, while in the prior year the obligation was valued using the Pri-2012 mortality table with generational projection using MP-2019. For years ended January 30, 2021 and February 1, 2020, we used the 2014 CPM Private Sector mortality table projected generationally with Scale CPM-B for both males and females to value its Canadian pension obligations for 2020. For the SERP Medical Plan, the mortality assumption used to value the 2020 obligation was updated to the PriH-2012 table with generational projection using MP-2020, while in the prior year the obligation was valued using the PriH-2012 table with generational projection using MP-2019.

Plan Assets

The target composition of our Canadian qualified pension plan assets is 95 percent fixed-income securities and 5 percent equities. We believe plan assets are invested in a conservative manner with the same overall objective and investment strategy as noted below for the U.S. pension plan. The bond portfolio is comprised of government and corporate bonds chosen to match the duration of the pension plan’s benefit payment obligations. This current asset allocation will limit future volatility with regard to the funded status of the plan.

The target composition of our U.S. qualified pension plan assets is 60 percent fixed-income securities, 36.5 percent equities, and 3.5 percent real estate. We may alter the asset allocation targets from time to time depending on market conditions and the funding requirements of the pension plan. This current asset allocation has and is expected to limit volatility with regard to the funded status of the plan, but may result in higher pension expense due to the lower long-term rate of return associated with fixed-income securities. Due to market conditions and other factors, actual asset allocations may vary from the target allocation outlined above.

We believe plan assets are invested in a conservative manner with an objective of providing a total return that, over the long term, provides sufficient assets to fund benefit obligations, taking into account our expected contributions and the level of funding risk deemed appropriate. Our investment strategy seeks to diversify assets among classes of investments with differing rates of return, volatility, and correlation in order to reduce funding risk. Diversification within asset classes is also utilized to ensure that there are no significant concentrations of risk in plan assets and to reduce the effect that the return on any single investment may have on the entire portfolio.

Valuation of Investments

Significant portions of plan assets are invested in commingled trust funds. These funds are valued at the net asset value of units held by the plan at year end. Stocks traded on U.S. and Canadian security exchanges are valued at closing market prices on the measurement date. The fair values of the Canadian pension plan assets at January 30, 2021 and February 1, 2020 were as follows:

Contributions and Expected Payments

We were not required to make any contributions to the U.S. qualified pension plans in 2020. During 2019, we made a contribution of $55 million to this plan. We do not anticipate making any contributions to the U.S. qualified pension plan in 2021 due to the strong funded status of the plan, however we continually evaluate the amount and timing of any potential contributions based on market conditions and other factors. We paid $1 million and $2 million in pension benefits related to our non-qualified pension plans during 2020 and 2019, respectively.

Estimated future benefit payments for each of the next five years and the five years thereafter are as follows:


	Pension		Postretirement
($ in millions)	Benefits		Benefits
2021	$	65	$	1
2022		53		1
2023		51		1

Savings Plans

We have two qualified savings plans, a 401(k) plan that is available to employees whose primary place of employment is the U.S., and another plan that is available to employees whose primary place of employment is in Puerto Rico. Eligible team members may contribute to the plans following 28 days of employment and are eligible for matching contributions upon completion of one year of service consisting of at least 1,000 hours. As of January 1, 2021, the savings plans allow eligible employees to contribute up to 40 percent of their compensation on a pre-tax basis, subject to a maximum of $19,500 for the U.S. plan and $15,000 for the Puerto Rico plan. Prior to January 1, 2020, we matched 25 percent of employees’ pre-tax contributions on up to the first 4 percent of the employees’ compensation (subject to certain limitations). Effective January 1, 2020, we match 100 percent of employees’ pre-tax contributions on up to the first 1 percent and 50 percent of the next 5 percent of the employees’ compensation (subject to certain limitations). Prior to January 1, 2020, such matching contributions were vested incrementally over the first five years of participation for both plans. Effective January 1, 2020, matching contributions are vested over two years. The charge to operations for matching contribution was $13 million and $4 million for 2020 and 2019, respectively.
