Postemployment Benefits [Abstract] |
Employee Benefit Plans | 7. Employee Benefit Plans Defined Contribution Retirement Savings Plan The Company has a defined contribution retirement savings plan with a 401(k) feature for all eligible U.S. and Canadian employees not under collective bargaining agreements. The Company matches a portion of the employee’s contribution and may make an additional contribution at its discretion. Contributions charged to expense under the plan for fiscal 2022, 2021 and 2020 were $18.2 million, $19.9 million and $16.6 million, respectively. Pension Plans and Supplemental Executive Retirement Plans The Company accounts for its pension plans and Supplemental Executive Retirement Plan on an accrual basis over employees’ estimated service periods. The Company maintains an unfunded Supplemental Executive Retirement Plan (“SERP”) for certain eligible employees of the Company. The benefits are based on the employee’s compensation upon retirement. The amount charged to expense related to this plan amounted to approximately $1.5 million, $2.9 million and $2.6 million for fiscal 2022, 2021 and 2020, respectively. The Company maintains a non-contributory defined benefit pension plan (“UniFirst Plan”) covering employees at one of its locations. The benefits are based on years of service. The UniFirst Plan assets are invested in a Guaranteed Deposit Account (“GDA”) that is maintained and operated by Prudential Retirement Insurance and Annuity Company (“PRIAC”). All assets are merged with the general assets of PRIAC and are invested predominantly in privately placed securities and mortgages. At the beginning of each calendar year, PRIAC notifies the Company of the annual rates of interest which will be applied to the amounts held in the GDA during the next calendar year. In determining the interest rate to be applied, PRIAC considers the investment performance of the underlying assets of the prior year; however, regardless of the investment performance the annual interest rate applied per the contract must be a minimum of 3.25%. The amount charged to expense related to this plan amounted to approximately $0.1 million for fiscal 2022 and $0.2 million for fiscal 2021 and 2020, respectively. In connection with one of the Company’s acquisitions, the Company assumed liabilities related to a frozen pension plan covering many of the acquired Company’s former employees (“Textilease Plan”). The Textilease Plan was terminated in fiscal 2020. The pension benefits were based on years of service and the employee’s compensation. The Textilease Plan assets were held in a separate GDA with PRIAC; however the minimum interest rate per the Textilease Plan contract was 1.5%. The amount charged to expense related to this plan amounted to approximately $0.5 million for fiscal 2020. There was no expense incurred related to this plan in either fiscal 2022 or 2021. The Company refers to its UniFirst Plan and Textilease Plan collectively as its “Pension Plans”. The components of net periodic benefit cost related to the Company’s Pension Plans and SERP for fiscal 2022, 2021 and 2020 were as follows (in thousands):

Nonqualified Deferred Compensation Plan The Company adopted the UniFirst Corporation Deferred Compensation Plan (the “NQDC Plan”) effective on February 1, 2022. The NQDC Plan is an unfunded, nonqualified deferred compensation plan that allows eligible participants to voluntarily defer receipt of their salary and annual cash bonuses up to approved limits. In its discretion, the Company may credit one or more additional contributions to participant accounts. NQDC Plan participants who are not accruing benefits under the Supplemental Executive Retirement Plan are eligible to have discretionary annual employer contributions credited to their NQDC Plan accounts. All participants are also eligible to have employer supplemental contributions and employer discretionary contributions credited to their NQDC Plan accounts. The amounts of such contributions may differ from year to year and from participant to participant. During the fiscal year ended August 27, 2022, the NQDC Plan had aggregate contributions of $1.3 million credited to participant accounts. The amount charged to expense was nominal for the year ended August 27, 2022. The Company, at its discretion, may also elect to transfer funds to a trust account with the intention to fund the future liability. Total NQDC Plan assets were $1.3 million as of August 27, 2022 and are included within other long-term assets on the balance sheet.
