Retirement Benefits [Abstract] |
Employee Benefit Plans | EMPLOYEE BENEFIT PLANS Pension Plans The Company has a defined benefit pension plan (the “UK Pension Plan”) that covers certain employees located in the United Kingdom who meet various eligibility requirements. Benefits are based on years of service and on a percentage of compensation near retirement. The UK Pension Plan is funded by contributions from the Company. The Company’s UK Pension Plan has a measurement date of May 31. The Company had a cash balance retirement plan (the “U.S. Pension Plan”), which covered the majority of United States employees who met certain eligibility requirements. On July 20, 2016, the Board approved the termination of the U.S. Pension Plan, as it was determined that the on-going costs of maintaining the U.S. Pension Plan were growing at a greater rate than the benefit delivered to the Company’s participating and former employees. In fiscal 2018, the U.S. Pension Plan made $37.8 of lump sum benefit payments to vested plan participants. The Company completed the final step in the distribution of the U.S. Pension Plan assets to participants by purchasing group annuity contracts for the remaining U.S. Pension Plan participants (the "U.S. Pension Plan Termination"). The total cost of these contracts was $86.3, paid to the respective insurers on February 21, 2018. The net funded asset position of the U.S. Pension Plan had previously included the value of the insurance contracts and lump sums settled prior to the purchase of such contracts. The U.S. Pension Plan's asset balance was sufficient to fund the purchase of these insurance contracts as well as any remaining benefit obligations and plan related operating expenses, with no additional cost to the Company as the plan sponsor. As a result, a remeasurement was completed on the final settlement date and a non-cash, pre-tax settlement expense of $57.3 was recognized in fiscal 2018 as a final settlement charge in the Company's consolidated statement of operations in Other components of net periodic benefit (cost). Postretirement Benefits The Company provides postretirement benefits to eligible retired United States-based employees (the “Postretirement Benefits”) consisting of certain healthcare and life insurance benefits. Employees may become eligible for these benefits after completing certain minimum age and service requirements. Effective June 1, 2009, the Company modified the terms of the Postretirement Benefits, effectively excluding a large percentage of employees from the plan. The Company’s postretirement benefit plan has a measurement date of May 31. In the second quarter of fiscal 2019, the Company made a change in benefits for certain postretirement benefit plan participants. Beginning January 1, 2019, the plan established Health Reimbursement Accounts (HRAs) to provide certain participants with additional flexibility to choose healthcare options based on individual needs. As a result of this change, the Company remeasured its Postretirement Benefit obligation as of November 30, 2018, and recognized a reduction of $2.7 to its benefit obligation and a reduction to its accumulated comprehensive loss of $2.7 in the second quarter of fiscal 2019. The related prior service credit will be amortized as a Component of net periodic benefit (cost) over the average remaining life expectancy of plan participants of approximately 13 years. The Medicare Prescription Drug, Improvement and Modernization Act (the “Medicare Act”) introduced a prescription drug benefit under Medicare (“Medicare Part D”) as well as a Federal subsidy of 28% to sponsors of retiree health care benefit plans providing a benefit that is at least actuarially equivalent to Medicare Part D. The Company has determined that the Postretirement Benefits provided to its retiree population are in aggregate the actuarial equivalent of the benefits under Medicare Part D. As a result, in fiscal 2019, 2018 and 2017, the Company recognized a cumulative reduction of its accumulated postretirement benefit obligation of $1.5, $2.3 and $2.5, respectively, due to the Federal subsidy under the Medicare Act. The following table sets forth the weighted average actuarial assumptions utilized to determine the benefit obligations for the U.S. Pension Plan and the UK Pension Plan (collectively the “Pension Plans”), including the Postretirement Benefits, at May 31:

* The U.S. Pension Plan was terminated in fiscal 2018. (1) The fiscal 2018 U.S. Pension Plan discount rate is for the period of June 1, 2017 through the plan settlement date. (2) The fiscal 2018 U.S. Pension Plan expected short-term return on plan assets is for the period of June 1, 2017 through the plan settlement date. To develop the expected long-term rate of return on plan assets assumption for the UK Pension Plan, the Company considers historical returns and future expectations. Considering this information and the potential for lower future returns due to a generally lower interest rate environment, the Company selected an assumed weighted average long-term rate of return on plan assets of 3.4% for the UK Pension Plan. In fiscal 2018, the U.S. Pension Plan utilized a short-term rate of return assumption of 4.8% due to the U.S. Pension Plan termination for the period June 1, 2017 through the plan settlement date. The following table sets forth the change in benefit obligation for the Pension Plans and Postretirement Benefits at May 31:

* The U.S. Pension Plan was terminated in fiscal 2018. (1) Funds which invest in a diversified portfolio of publicly traded U.S. common stocks of large-cap, medium-cap and small-cap companies. There are no restrictions on these investments. (2) Funds which invest in a diversified portfolio of publicly traded common stocks of non-U.S. companies, primarily in Europe and Asia. There are no restrictions on these investments. (3) Funds which invest in UK government bonds and bond index-linked investments and interest rate and inflation swaps. There are no restrictions on these investments. (4) Funds which invest in bond index funds available to certain qualified retirement plans but not traded openly in any public exchanges. There are no restrictions on these investments. (5) Represents assets of a non-U.S. entity plan invested in a fund whose underlying investments are comprised of properties. The fund has publicly available quoted market prices and there are no restrictions on these investments. The Company has purchased annuities to service fixed payments to certain retired plan participants in the UK. These annuities are purchased from investment grade counterparties. These annuities are not traded on open markets and are therefore valued based upon the actuarial determined valuation, and related assumptions, of the underlying projected benefit obligation, a Level 3 valuation technique. The fair value of these assets was $5.5 and $5.7 at May 31, 2019 and May 31, 2018, respectively.

2022 | 0.9 |  |  | 1.9 |  |  | 0.1 |
2023 | 1.3 |  |  | 1.9 |  |  | 0.2 |
2024 | 1.2 |  |  | 1.9 |  |  | 0.2 |
2025 and thereafter | 10.2 |  |  | 8.5 |  |  | 0.8 |
Beneficiary payments for the U.S. Pension Plan were paid in full in fiscal 2018. Assumed health care cost trend rates at May 31:
| 2019 |  | 2018
Health care cost trend rate assumed for the next fiscal year | 6.5 | % |  | 6.8 | %
Rate to which the cost trend is assumed to decline (the ultimate trend rate) | 5.0 | % |  | 5.0 | %
Year that the rate reaches the ultimate trend rate | 2026 |  |  | 2026 |
Assumed health care cost trend rates could have a significant effect on the amounts reported for the postretirement health care plan. A one percentage point change in assumed health care cost trend rates would have the following effects:
| 2019 |  | 2018
Total service and interest cost - 1% increase | $ | 0.1 |  |  | $ | 0.1 |
Total service and interest cost - 1% decrease | (0.1 | ) |  | (0.1 | )
Postretirement benefit obligation - 1% increase | 2.1 |  |  | 2.8 |
Postretirement benefit obligation - 1% decrease | (1.9 | ) |  | (2.4 | )
Defined contribution plans The Company also provides defined contribution plans for certain eligible employees. In the United States, the Company sponsors a 401(k) retirement plan and has contributed $7.6, $7.2 and $7.1 for fiscal years 2019, 2018 and 2017, respectively.
