Retirement Benefits [Abstract] |
EMPLOYEES' RETIREMENT PLANS | NOTE 16. EMPLOYEES' RETIREMENT PLANS Substantially all employees in the U.S. are covered by a defined contribution 401(k) retirement plan. The tax qualified defined contribution plan is maintained, and contributions are made, in accordance with the Employee Retirement Income Security Act of 1974, as amended ("ERISA"). The Company also provides certain eligible executives benefits pursuant to its Benefit Restoration Plan ("BRP") equal to amounts that would have been available under the tax qualified ERISA plan, but were subject to the limitations of ERISA, tax laws and regulations. Company expenses for these plans, a portion of which are discretionary, are recorded in both cost of goods sold and selling, general and administrative expenses, and totaled $37.3 million, $32.9 million and $27.3 million for 2020, 2019 and 2018, respectively. The deferred compensation liability under the BRP was $47.0 million and $45.7 million at August 31, 2020 and 2019, respectively, with $40.6 million and $39.9 million, respectively, included in other long-term liabilities on the Company's consolidated balance sheets. At August 31, 2020 and 2019, $6.4 million and $5.8 million, respectively, of the deferred compensation liability related to the BRP was included in accrued expenses and other payables on the Company's consolidated balance sheets. Though under no obligation to fund the BRP, the Company has segregated assets in a trust with a value of $60.8 million and $56.3 million at August 31, 2020 and 2019, respectively, and such assets were included in other noncurrent assets on the Company's consolidated balance sheets. The net holding gain on these segregated assets was $6.0 million, $3.3 million and $9.3 million for 2020, 2019 and 2018, respectively, and was included in net sales in the Company's consolidated statements of earnings. In 2019, the Company acquired certain assets, including a partially funded defined benefit pension plan, from Gerdau S.A., (the "Plan") as part of the Acquisition. Upon closing of the Acquisition, the excess of projected Plan benefit obligations over the Plan assets was recognized as a liability and previously existing deferred actuarial gains and losses and unrecognized service costs or benefits were eliminated. Pension benefits associated with the Plan are generally based on each participant’s years of service, compensation and age at retirement or termination. The Plan was closed to new participants prior to the Acquisition. In 2020, the Company announced its decision to close the melting operations at its Rancho Cucamonga facility and then subsequently announced its decision to sell this same facility. As a result of these announcements, the Company recorded a pension curtailment of $3.2 million in 2020. The following tables include a reconciliation of the beginning and ending balances of pension benefit obligation and the fair value of Plan assets and the related amounts recognized in the Company’s consolidated balance sheets as of August 31, 2020 and 2019.

The pension accumulated benefit obligation represents the actuarial present value of benefits based on employee service and compensation as of the measurement date and does not include an assumption about future compensation levels. The service cost component of net periodic benefit cost is recorded in cost of goods sold. Components of net periodic benefit cost and other supplemental information are detailed below.

__________________________________ (1)Certain weighted average assumptions used to determine net periodic benefit cost for 2020 were remeasured at an interim date. This remeasurement resulted in an effective rate for interest on benefit obligations of 2.9% and an effective rate for service cost of 3.5%. The Company determines the discount rate used to measure liabilities as of the August 31 measurement date for the Plan, which is also the date used for the related annual measurement assumptions. The discount rate reflects the current rate at which the associated liabilities could be effectively settled at the end of the year. The Company sets its rate to reflect the yield of a portfolio of high quality corporate bonds that would produce cash flows sufficient in timing and amount to settle projected future benefits. The Company measures service cost and interest cost separately using the full yield curve approach applied to each corresponding obligation. Service costs are determined based on duration-specific spot rates applied to the service cost cash flows. The interest cost calculation is determined by applying duration-specific spot rates to the year-by-year projected benefit payments. The full yield curve approach does not affect the measurement of the total benefit obligations. The Company’s assumption for the expected return on Plan assets was 6% in 2020. Projected returns are based primarily on broad, publicly traded equity and fixed income indices and forward-looking estimates. As of August 31, 2020, the Company’s expected long-term rate of return on Plan assets for 2021 is 5%. The expected return assumption is based on the strategic asset allocation of the Plan and long-term capital market return expectations. The Company does not expect to make any contributions in 2021. Future contributions will depend on market conditions, interest rates and other factors. Plan Assets Plan assets consist primarily of public equity and corporate bonds. The principal investment objectives are to maximize total return without assuming undue risk exposure. Each asset class has broadly diversified characteristics. Asset and benefit obligation forecasting studies are conducted periodically, generally every two to three years, or when significant changes have occurred in market conditions, benefits, participant demographics or funded status. The Plan's weighted average asset targets and actual allocations as a percentage of Plan assets, including the notional exposure of future contracts by asset categories, are detailed below.

Investment Valuation Investments are stated at fair value. Fair value is the price that would be received to sell an asset or paid to transfer a liability at the measurement date. Investments in securities traded on a national securities exchange are valued at the last reported sales price on the final business day of the year. Fixed income securities are valued at the yields currently available on comparable securities of issues with similar credit ratings. Purchases and sales of securities are recorded as of the trade date. Realized gains and losses on sales of securities are determined based on average cost. Interest income is recognized on the accrual basis. Dividend income is recognized on the ex-dividend date. Non-interest bearing cash is valued at cost, which approximates fair value. Fair Value Measurements The following table sets forth the Plan assets by asset class as of August 31, 2020 and 2019. All securities are traded on a national securities exchange and therefore are Level 1 assets in the fair value hierarchy.
