Employee Benefits |
Employee Benefits | Note 13. Employee Benefits ​ Defined Contribution Plans ​ Effective in 1998, the Reliance Steel & Aluminum Co. Master 401(k) Plan (the “Master 401(k) Plan”) was established, which combined several of the various 401(k) and profit-sharing plans of the Company and its subsidiaries into one plan. Salaried and certain hourly employees of the Company and its participating subsidiaries are covered under the Master 401(k) Plan. Eligibility occurs after 30 days of service and the Company contribution vests at 25% per year. We have other defined contribution plans that include the Precision Strip Retirement and Savings Plan and plans at certain domestic and foreign subsidiaries that have not merged their plans into the Master 401(k) Plan as of December 31, 2023 (collectively, the “Other Defined Contribution Plans”). ​ We also sponsor the Reliance Steel & Aluminum Co. Employee Stock Ownership Plan, a tax-qualified noncontributory employee stock ownership plan, for certain salaried and hourly employees of the Company. The plan is closed to new enrollees and the Company is not currently making annual contributions to the plan. ​ Supplemental Executive Retirement Plans ​ Effective January 1996, we adopted the Supplemental Executive Retirement Plan (“Reliance SERP”), which is a nonqualified pension plan that provides postretirement pension benefits to certain key officers of the Company. The Reliance SERP is administered by the Compensation Committee of the Board. Benefits are based upon the employees’ earnings. We recognized settlement losses of $2.3 million in the year ended December 31, 2022 related to the payment of benefits under the Reliance SERP. ​ Life insurance policies were purchased for most individuals covered by the Reliance SERP and held within a grantor trust. See Note 8—“Cash Surrender Value of Life Insurance Policies, Net” for further discussion of our life insurance policies. Separate supplemental executive retirement plans exist for certain wholly owned subsidiaries of the Company (together with the Reliance SERP, the “SERPs”), each of which provides postretirement pension benefits to certain former key employees. All SERPs have been frozen to new participants since 2009. ​ Deferred Compensation Plan ​ In December 2008, the Reliance Deferred Compensation Plan (the “DCP”) was established for certain officers and key employees of the Company. Account balances from various compensation plans of subsidiaries were contributed and consolidated into this new deferred compensation plan. Plan participants may contribute a portion of their eligible compensation to the plan and Reliance currently makes contributions to the plan for certain participants. ​ During 2021, we established a grantor trust to fund our obligations under the DCP. The grantor trust is an irrevocable grantor trust to which we may contribute assets for the purpose of funding the DCP. Although we may not use the assets of the grantor trust for any purpose other than meeting our obligations under the DCP, the assets of the grantor trust remain subject to the claims of our creditors. The aggregate fair value of the marketable securities held by the grantor trust as of December 31, 2023 and 2022 were $51.0 million and $41.2 million, respectively, and the amount of our obligations to the participants under the DCP on those dates were also $51.0 million and $41.2 million, respectively. The grantor trust assets and our liability under the DCP are included in the Other long-term assets and Other long-term liabilities captions of our consolidated balance sheets. The Company expects to contribute $2.4 million to the plan during 2024. ​ Multiemployer Plans ​ Certain of our union employees participate in plans collectively bargained and maintained by multiple employers and a labor union. We do not recognize on our balance sheet any amounts relating to these plans. For 2023, 2022 and 2021 our contributions to these plans were $5.4 million, $5.4 million and $4.8 million, respectively. Some of the plans we participate in are in endangered, critical or critical and declining status and have adopted rehabilitation plans. If we were to withdraw our participation from these plans, we would be required to recognize a liability on our balance sheet and the amount could be significant. ​ Defined Benefit Plan ​ Our wholly owned subsidiary, EMJ, maintains a qualified defined benefit pension plan (the “Defined Benefit Plan”) for certain union employees. The plan generally provides benefits of stated amounts for each year of service or provides benefits based on the participant’s hourly wage rate and years of service. The plan permits the sponsor, at any time, to amend or terminate the plan. ​ ​ We use a December 31 measurement date for our plans. The following is a summary of the status of the funding of the SERPs and Defined Benefit Plan: ​

​ Employer contributions of $0.8 million are expected during 2024 to the SERPs and none for the Defined Benefit Plan. ​ Plan Assets and Investment Policy ​ The weighted-average asset allocations of our Defined Benefit Plan by asset category were as follows: ​
​ | ​ | ​ | ​ | ​
​ | December 31, | ​
​ | 2023 |  | 2022 | ​
Plan assets: | ​ | ​ | ​ | ​
Equity securities | 62 | % | 58 | %
Debt securities | 37 | ​ | 38 | ​
Cash and cash equivalents | 1 | ​ | 4 | ​
Total | 100 | % | 100 | %
​ Plan assets are invested in various asset classes that are expected to produce a sufficient level of diversification and investment return over the long term. The investment goal is a return on assets that is at least equal to the assumed actuarial rate of return over the long-term within reasonable and prudent levels of risk. We establish our estimated long-term return on plan assets assumption considering various factors including the targeted asset allocation percentages, historic returns and expected future returns. ​ The fair value measurements of the investments held by our Defined Benefit Plan fall within the following levels of the fair value hierarchy as of December 31, 2023 and 2022: ​
