Compensation and Retirement Disclosure [Abstract] |
Compensation and Employee Benefit Plans | Employee Benefit Plans The company maintains retirement benefit plans for substantially all of its employees. Pension Plans and Post-Retirement Medical Insurance The company offers certain employees retirement benefits under domestic defined benefit p lans. The company provides healthcare benefits to employees who retired from service on or before a qualifying date in 1998. As of the qualifying date, the company discontinued offering post-retirement medical to future retirees. Benefits to qualifying retirees under this plan are based on the employee's years of service and age at the date of retirement. In addition to the domestic pension and retiree healthcare plan, one of the company's wholly owned foreign subsidiaries has a defined-benefit pension plan based upon an average final pay benefit calculation. The measurement date for the company's principal domestic and international pension plans, as well as its post-retirement medical plan, is the last day of the fiscal year. During fiscal 2014, the company settled the remaining obligations associated with its primary domestic defined benefit pension plans. Plan participants received vested benefits from the plan assets by electing either a lump sum distribution, roll-over contribution to other 401(k) or individual retirement plans, or an annuity contract with a qualifying third-party provider. As a result of the settlement, the company was relieved of any further obligation. Pension settlement charges of $158.2 million, before tax, were recorded during fiscal year 2014. The settlement expenses included the pre-tax reclassifications of actuarial gains and losses from accumulated other comprehensive loss of $137.7 million, and cash contributions to the plan of $48.8 million, net of the outstanding pension plan liability prior to settlement. Cost of goods sold included $49.3 million of the settlement expense, while $108.9 million of the expense was included in operating expenses. After the settlement, the remaining pension assets of $0.9 million were transferred to the company's defined contribution 401(k) plan. The primary domestic defined-benefit plan included benefits determined by a cash balance calculation. Benefits under this plan were based upon an employee's years of service and earnings. Benefit Obligations and Funded Status The following table presents, for the fiscal years noted, a summary of the changes in the projected benefit obligation, plan assets and funded status of the company's domestic and international pension plans and post-retirement plan:

The net actuarial loss, incl uded in accumulated other comprehensive loss (pretax), expected to be recognized in net periodic benefit cost during fiscal 2017 is $2.5 million. Actuarial Assumptions The weighted-average actuarial assumptions used to determine the benefit obligation amounts and the net periodic benefit cost for the company's pension and post-retirement plans are as follows:
The weighted-average used in the determination of net periodic benefit cost:
| 2016 |  | 2015 |  | 2014
(Percentages) | Domestic |  | International |  | Domestic |  | International |  | Domestic |  | International
Discount rate | 3.41 |  | 3.50 |  | 3.44 |  | 4.40 |  | 3.43 |  | 4.40
Compensation increase rate | n/a |  | 3.20 |  | n/a |  | 3.35 |  | n/a |  | 3.50
Expected return on plan assets | n/a |  | 6.10 |  | n/a |  | 6.10 |  | n/a |  | 6.00
The weighted-average used in the determination of the projected benefit obligations:
Discount rate | 3.51 |  | 3.43 |  | 3.41 |  | 3.50 |  | 3.44 |  | 4.40
Compensation increase rate | n/a |  | 2.95 |  | n/a |  | 3.20 |  | n/a |  | 3.35
Effective May 28, 2016, the company changed the method it uses to estimate the interest component of net periodic benefit cost for pension and other postretirement benefits. Historically, the company has estimated the interest cost component utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. The company has elected to utilize a full yield curve approach in the estimation of interest cost by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. The company has made this change to provide a more precise measurement of interest cost by improving the correlation between projected benefit cash flows to the corresponding spot yield curve rates. The company accounted for this change as a change in accounting estimate and accordingly will account for it prospectively. The company estimates the impact of this change on the consolidated earnings for fiscal 2017 will be a reduction of the interest cost component of net periodic benefit cost of approximately $0.4 million. For fiscal 2016, the use of the full yield curve approach did not impact how the company measured the total benefit obligations at year end or the annual net periodic benefit cost as any change in the interest cost component is completely offset by the actuarial gain or loss measured at year end, which is immediately recognized in the income statement. Accordingly, this change in estimate did not impact the Consolidated Statement of Comprehensive Income for the fiscal year ended May 28, 2016. In calculating post-retirement benefit obligations for fiscal 2016, a 7.9 percent annual rate of increase in the per capita cost of covered healthcare benefits was assumed for 2016, decreasing gradually to 4.3 percent by 2038 and remaining at that level thereafter. For purposes of calculating post-retirement benefit costs, a 7.1 percent annual rate of increase in the per capita cost of covered healthcare benefits was assumed for 2016, decreasing gradually to 4.5 percent by 2029 an d remaining at that level thereafter. Assumed health care cost-trend rates have a significant effect on the amounts reported for retiree health care costs. A one-percentage-point change in the assumed health care cost-trend rates would have the following effects:
(In millions) | 1 Percent Increase |  | 1 Percent Decrease
Effect on total fiscal 2016 service and interest cost components | $ | — |  |  | $ | — |
Effect on post-retirement benefit obligation at May 28, 2016 | $ | 0.2 |  |  | $ | (0.2 | )
Plan Assets and Investment Strategies The assets related to the company's primary domestic employee benefit plans were liquidated in connection with the plan termination that occurred during fiscal 2014. Accordingly, plan assets for the primary domestic employee benefit plans were zero as of the end of fiscal 2014. The company's international employee benefit plan assets consist mainly of listed fixed income obligations and common/collective trusts. The company's primary objective for invested pension plan assets is to provide for sufficient long-term growth and liquidity to satisfy all of its benefit obligations over time. Accordingly, the company has developed an investment strategy that it believes maximizes the probability of meeting this overall objective. This strategy includes the development of a target investment allocation by asset category in order to provide guidelines for making investment decisions. This target allocation emphasizes the long-term characteristics of individual asset classes as well as the diversification among multiple asset classes. In developing its strategy, the company considered the need to balance the varying risks associated with each asset class with the long-term nature of its benefit obligations. The company's strategy moving forward will be to increase the level of fixed income investments as the funding status improves, thereby more closely matching the return on assets with the liabilities of the plans. The company utilizes independent investment managers to assist with investment decisions within the overall guidelines of the investment strategy. The target asset allocation at the end of fiscal 2016 and asset categories for the company's primary international pension plan for fiscal 2016 and 2015 is as follows:
Asset Category |  | Targeted Asset Allocation Percentage |  | Percentage of Plan Assets at Year End
|  | 2016 |  | 2015
Equities |  | — |  | — |  | 2
Fixed Income |  | 20 |  | 24 |  | 23

Cash Flows The company is reviewing whether any additional voluntary pension plan contributions will be made in the next year. Actual contributions will be dependent upon investment returns, changes in pension obligations, and other economic and regulatory factors. During fiscal 2016, the company made total cash contributions of $1.2 million to its benefit plans. In fiscal 2015, the company made total cash contributions of $1.4 million to its benefit plans. The following represents a summary of the benefits expected to be paid by the plans in future fiscal years. These expected benefits were estimated based on the same actuarial valuation assumptions used to determine benefit obligations at May 28, 2016.

Profit Sharing, 401(k) Plan, and Core Contribution Substantially all of the company’s domestic employees are eligible to participate in a defined contribution retirement plan, primarily the Herman Miller, Inc. profit sharing and 401(k) plan. Employees under the Herman Miller, Inc. profit sharing plan are eligible to begin participating on their date of hire. The Profit Sharing plan provides for discretionary contributions for eligible participants, payable in the company's common stock, of not more than 6 percent of employees' wages based on the company's financial performance. Under the Herman Miller, Inc. 401(k) plan the company matches 100 percent of employee contributions to their 401(k) accounts up to 3 percent of their pay. A core contribution of 4 percent is also included for most participants of the plan. The company’s other defined contribution retirement plans may provide for matching contributions, non-elective contributions and discretionary contributions as declared by management. The cost of the Herman Miller, Inc. profit sharing contribution during fiscal 2016, 2015, and 2014 was $10.9 million, $4.8 million and $6.4 million, respectively. The expense recorded for the company's 401(k) matching contributions and core contributions was approximately $21.9 million, $20.8 million, and $20.3 million in fiscal years 2016, 2015 and 2014, respectively.
