Compensation And Retirement Disclosure [Abstract] |
Defined Contribution and Defined Benefit Retirement | Note 11—Defined contribution and defined benefit retirement: Defined contribution plans. Certain of our subsidiaries maintain various defined contribution pension plans for our employees worldwide. Defined contribution plan expense approximated $6.6 million in 2018, $6.5 million in 2019 and $6.6 million in 2020. Defined benefit plans. Kronos and NL sponsor various defined benefit pension plans worldwide. The benefits under our defined benefit plans are based upon years of service and employee compensation. Our funding policy is to contribute annually the minimum amount required under ERISA (or equivalent foreign) regulations plus additional amounts as we deem appropriate. We recognize an asset or liability for the over or under funded status of each of our individual defined benefit pension plans on our Consolidated Balance Sheets. Changes in the funded status of these plans are recognized either in net income, to the extent they are reflected in periodic benefit cost, or through other comprehensive income (loss). In accordance with applicable U.K. pension regulations, we entered into an agreement in March 2021 for the bulk annuity purchase, or “buy-in” with a specialist insurer of defined benefit pension plans. Following the buy-in, individual policies will replace the bulk annuity policy in a “buy-out” which is expected to be completed in late 2021 or early 2022. The buy-out is expected to be completed with existing plan funds. At the completion of the buy-out we will remove the assets and liabilities of the U.K. pension plan from our Consolidated Financial Statements and a plan settlement gain or loss (which we are currently unable to estimate) will be included in net periodic pension cost. At December 31, 2020 the U.K. plan had a benefit obligation of $12.2 million, plan assets of $17.3 million and a pension plan asset of $5.2 million was recognized in our Consolidated Balance Sheet. We expect to contribute the equivalent of approximately $18 million to all of our defined benefit pension plans during 2021. Benefit payments to plan participants out of plan assets are expected to be the equivalent of:
2021 | $ 27.5 million
2022 | 28.9 million
2023 | 28.7 million
2024 | 30.6 million
2025 | 30.6 million
Next 5 years | 177.6 million

The total net underfunded status of our U.S. defined benefit pension plans decreased from $12.2 million at December 31, 2019 to $9.9 million at December 31, 2020 due to the change in our plan assets during 2020 exceeding the change in our PBO during 2020. The increase in our PBO in 2020 was primarily attributable to actuarial losses due to the decrease in discount rates from year end 2019. The increase in our plan assets in 2020 was primarily attributable to net plan asset returns in 2020 and employer contributions. The components of our net periodic defined benefit pension cost for U.S. plans are presented in the table below. The amounts shown below for the amortization of unrecognized actuarial losses for 2018, 2019 and 2020 were recognized as components of our accumulated other comprehensive income (loss) at December 31, 2017, 2018 and 2019, respectively, net of deferred income taxes and noncontrolling interest.

The discount rate assumptions used in determining the actuarial present value of the benefit obligation for our U.S. defined benefit pension plans as of December 31, 2019 and 2020 are 3.1% and 2.2%, respectively. The impact of assumed increases in future compensation levels does not have an effect on the benefit obligation as the plans are frozen with regards to compensation. The weighted-average rate assumptions used in determining the net periodic pension cost for our U.S. defined benefit pension plans for 2018, 2019 and 2020 are presented in the table below. The impact of assumed increases in future compensation levels does not have an effect on the periodic pension cost as the plans are frozen with regards to compensation.

The total net underfunded status of our non-U.S. defined benefit pension plans increased from $296.4 million at December 31, 2019 to $361.0 million at December 31, 2020 due to the change in our PBO during 2020 exceeding the change in plan assets during 2020. The increase in our PBO in 2020 was primarily attributable to actuarial losses due to the decrease in discount rates from year end 2019 and unfavorable foreign currency fluctuations resulting primarily from the weakening of the U.S. dollar relative to the euro. The increase in our plan assets in 2020 was primarily attributable to net plan asset returns in 2020, employer contributions and favorable foreign currency fluctuations resulting primarily from the weakening of the U.S. dollar relative to the euro. The components of our net periodic pension benefit cost for our foreign plans are presented in the table below. The amounts shown below for the amortization of unrecognized prior service cost and actuarial losses for 2018, 2019 and 2020 were recognized as components of our accumulated other comprehensive income (loss) at December 31, 2017, 2018 and 2019, respectively, net of deferred income taxes and noncontrolling interest.

Variances from actuarially assumed rates will result in increases or decreases in accumulated pension obligations, pension expense and funding requirements in future periods. The amounts shown for all of our periodic defined benefit plans for unrecognized actuarial losses and prior service cost at December 31, 2019 and 2020 have not been recognized as components of our periodic defined benefit pension cost as of those dates. These amounts will be recognized as components of our periodic defined benefit cost in future years. These amounts, net of deferred income taxes and noncontrolling interest, are recognized in our accumulated other comprehensive income (loss) at December 31, 2019 and 2020. We expect approximately $21.0 million and $.2 million of the unrecognized actuarial losses and prior service cost, respectively, will be recognized as components of our periodic defined benefit pension cost in 2021. The table below details the changes in other comprehensive income (loss) during 2018, 2019 and 2020.

Prior to 2018, substantially all of the assets attributable to our U.S. plan were invested in the Combined Master Retirement Trust (CMRT), a collective investment trust sponsored by Contran to permit the collective investment by certain master trusts that fund certain employee benefit plans sponsored by Contran and certain of its affiliates, including us. For 2018, the long-term rate of return assumption for our U.S. plan assets was 7.5%, based on the long-term asset mix of the assets of the CMRT and the expected long-term rates of return for such asset components as well as advice from Contran’s actuaries. During 2018, Contran and the other employer-sponsors (including us) implemented a restructuring of the CMRT, in which a substantial part of each plan’s units in the CMRT were redeemed in exchange for a pro-rata portion of a substantial part of the CMRT’s investments. Following such restructuring, the plans held directly in the aggregate the investments previously held directly by the CMRT which had been exchanged for CMRT units as part of the restructuring. Certain investments held directly by the CMRT were not part of such restructuring and remained investments of the CMRT at December 31, 2018. During 2019, the remaining investments of the CMRT allocable to our U.S. plan were transferred and are held as direct investments of our U.S. plan at December 31, 2019 and December 31, 2020. Such restructuring was implemented in part so each plan could more easily align the composition of its plan asset portfolio with the plan’s benefit obligations. In determining the expected long-term rate of return on plan asset assumptions, we consider the long-term asset mix (e.g. equity vs. fixed income) for the assets for each of our plans and the expected long-term rates of return for such asset components. In addition, we receive third-party advice about appropriate long-term rates of return. Such assumed asset mixes are summarized below:
| ● | In Germany, the composition of our plan assets is established to satisfy the requirements of the German insurance commissioner. Our German pension plan assets represent an investment in a large collective investment fund established and maintained by Bayer AG in which several pension plans, including our German pension plans and Bayer’s pension plans, have invested. Our plan assets represent a very nominal portion of the total collective investment fund maintained by Bayer. These plan assets are a Level 3 in the fair value hierarchy because there is not an active market that approximates the value of our investment in the Bayer investment fund. We estimate the fair value of the Bayer plan assets based on periodic reports we receive from the managers of the Bayer fund and using a model we developed with assistance from our third-party actuary that uses estimated asset allocations and correlates such allocation to similar asset mixes in fund indexes quoted on an active market. We periodically evaluate the results of our valuation model against actual returns in the Bayer fund and adjust the model as needed. The Bayer fund periodic reports are subject to audit by the German pension regulator.
| ● | In Canada, we currently have a plan asset target allocation of 20% to 30% to equity securities and 70% to 80% to fixed income securities. We expect the long-term rate of return for such investments to approximate the applicable equity or fixed income index. The Canadian assets are Level 1 inputs because they are traded in active markets.
| ● | In Norway, we currently have a plan asset target allocation of 15% to equity securities, 62% to fixed income securities, 14% to real estate and the remainder primarily to other investments and liquid investments such as money markets. The expected long-term rate of return for such investments is approximately 5%, 3%, 4% and 7%, respectively. The majority of Norwegian plan assets are Level 1 inputs because they are traded in active markets; however approximately 14% of our Norwegian plan assets are invested in real estate and other investments not actively traded and are therefore a Level 3 input.
| ● | In the U.S. we currently have a plan asset target allocation of 38% to equity securities, 54% to fixed income securities, and the remainder is allocated to multi-asset strategies. The expected long-term rate of return for such investments is approximately 9%, 3% and 2%, respectively (before plan administrative expenses). The majority of U.S. plan assets are Level 1 inputs because they are traded in active markets, and approximately 34% of our U.S. plan assets are invested in funds that are valued at net asset value (NAV) and not subject to classification in the fair value hierarchy
| ● | We also have plan assets in Belgium and the United Kingdom. The Belgian plan assets are invested in certain individualized fixed income insurance contracts for the benefit of each plan participant as required by the local regulators and are therefore a Level 3 input. The United Kingdom plan assets consist of marketable securities which are Level 1 inputs because they trade in active markets.
We regularly review our actual asset allocation for each plan, and will periodically rebalance the investments in each plan to more accurately reflect the targeted allocation and/or maximize the overall long-term return when considered appropriate. The composition of our pension plan assets by asset category and fair value level at December 31, 2019 and 2020 is shown in the tables below.
