Pension and Postretirement Benefits
 
Defined Contribution Plan
 
All U.S. employees have the option of contributing up to
75
percent of their pre-tax earnings to a
401
(k) plan, subject to IRS limitations. We match up to the
first
4
percent of each employee's pre-tax earnings, based on the employee’s contributions. All U.S. employees are eligible for a separate annual retirement contribution to the
401
(k) plan of
3
percent of pay, that is invested based on the election of the individual participant. The
3
percent contribution is in addition to our
4
percent matching contribution described above and is in lieu of participation in our defined benefit pension plan. The total contribution to the
401
(k) plan for
2018
was
$11,034
which included the cost of the
4
percent company match of
$5,293
and the additional
3
percent contribution of
$5,741.
The total contributions to the
401
(k) plan were
$10,899
and
$10,417
in
2017
and
2016,
respectively.
 
The defined contribution plan liability recorded in the Consolidated Balance Sheets was
$20,183
and
$6,307
in
2018
and
2017,
respectively for the U.S. Plan and several statutorily required non-U.S. Plans.
 
Defined Benefit Plan
s
 
Noncontributory defined benefit pension plans cover all U.S. employees employed prior to
January 1, 2007.
Benefits for these plans are based primarily on each employee’s years of service and average compensation.  During
2011,
we made significant changes to our U.S. Pension Plan.  The changes included: benefits under the U.S. Pension Plan were locked-in using service and salary as of
May 31, 2011,
participants
no
longer earn benefits for future service and salary as they had in the past, affected participants receive a
three
percent increase to the locked-in benefit for every year they continue to work for us and we are making a retirement contribution of
three
percent of eligible compensation to the
401
(k) Plan for those participants.  The funding policy is consistent with the funding requirements of federal law and regulations.  Plan assets consist principally of listed equity securities and bonds.  During
2015,
we amended the U.S. Pension Plan to add a program for eligible employees to take a lump sum distribution. 
No
lump sum payments were paid during
2018
and
2017.
Lump sum payments of
$8,399
were made during
2016
under this program.  Other U.S. postretirement benefits are funded through a Voluntary Employees' Beneficiaries Association Trust.
 
Health care and life insurance benefits are provided for eligible retired employees and their eligible dependents. These benefits are provided through various insurance companies and health care providers. Costs are accrued during the years the employee renders the necessary service.
 
Certain non-U.S. subsidiaries provide pension benefits for their employees consistent with local practices and regulations. These plans are primarily defined benefit plans covering substantially all employees upon completion of a specified period of service. Benefits for these plans are generally based on years of service and annual compensation.
 
Following is a reconciliation of the beginning and ending balances of the benefit obligation and fair value of plan assets as of
December 1, 2018

Actuarial gain in
2018
and actuarial loss in
2017
for the U.S. Plans is primarily due to assumption changes. Actuarial gains in
2018
and
2017
for the Non-U.S. Plans are due to both assumption changes and plan experience.

Benefits under the U.S. Pension Plan were locked-in as of
May 31, 2011
and
no
longer include compensation increases. The
4.50
percent rate for
2018,
2017
 and
2016
 are for the supplemental executive retirement plan only.
 
The discount rate assumption is determined using an actuarial yield curve approach, which results in a discount rate that reflects the characteristics of the plan. The approach identifies a broad population of corporate bonds that meet the quality and size criteria for the particular plan. We use this approach rather than a specific index that has a certain set of bonds that
may
or
may
not
be representative of the characteristics of our particular plan. A higher discount rate decreases the present value of the pension obligations. The discount rate for the U.S. pension plan was
4.51
percent at
December 1, 2018,
compared to
3.73
percent at
December 2, 2017
and
4.10
percent at
December 3, 2016.
Net periodic pension cost for a given fiscal year is based on assumptions developed at the end of the previous fiscal year. A discount rate reduction of
0.5
percentage points at
December 1, 2018
would decrease pension and other postretirement plan expense approximately
$22
(pre-tax) in fiscal
2019.
Discount rates for non-U.S. plans are determined in a manner consistent with the U.S. plan.
 
For the U.S. Pension Plan, we adopted the Adjusted RP-
2014
mortality tables projected generationally using scale MP-
2018.
 
The expected long-term rate of return on plan assets assumption for the U.S. pension plan was
7.75
percent in
2018,
2017
and
2016.
  Our expected long-term rate of return on U.S. plan assets was based on our target asset allocation assumption of
60
percent equities and
40
percent fixed-income. Management, in conjunction with our external financial advisors, determines the expected long-term rate of return on plan assets by considering the expected future returns and volatility levels for each asset class that are based on historical returns and forward-looking observations. For
2018,
the expected long-term rate of return on the target equities allocation was
8.25
percent and the expected long-term rate of return on the target fixed-income allocation was
5.6
percent. The total plan rate of return assumption included an estimate of the effect of diversification and the plan expense. A change of
0.5
percentage points for the expected return on assets assumption would impact U.S. net pension and other postretirement plan expense by approximately
$2,147
(pre-tax).
 
Management, in conjunction with our external financial advisors, uses the actual historical rates of return of the asset categories to assess the reasonableness of the expected long-term rate of return on plan assets.
 
The expected long-term rate of return on plan assets assumption for non-U.S. pension plans was a weighted-average of
6.20
percent in
2018
compared to
6.21
percent in
2017
and
6.20
percent in
2016.
The expected long-term rate of return on plan assets assumption used in each non-U.S. plan is determined on a plan-by-plan basis for each local jurisdiction and is based on expected future returns for the investment mix of assets currently in the portfolio for that plan.  Management, in conjunction with our external financial advisors, develops expected rates of return for each plan, considers expected long-term returns for each asset category in the plan, reviews expectations for inflation for each local jurisdiction, and estimates the effect of active management of the plan’s assets. Our largest non-U.S. pension plans are in the United Kingdom and Germany, respectively. The expected long-term rate of return on plan assets for the United Kingdom was
6.75

Plan Asset Management
 
Plan assets are held in trust and invested in mutual funds, separately managed accounts and other commingled investment vehicles holding U.S. and non-U.S. equity securities, fixed income securities and other investment classes. We employ a total return approach whereby a mix of equities and fixed income investments are used to maximize the long-term return of plan assets for a prudent level of risk. Futures and options
may
also be used to enhance risk-adjusted long-term returns while improving portfolio diversification and duration. Risk management is accomplished through diversification across asset classes, utilization of multiple investment managers and general plan-specific investment policies. Risk tolerance is established through careful consideration of the plan liabilities, plan funded status and our assessment of our overall liquidity position. This asset allocation policy mix is reviewed annually and actual versus target allocations are monitored regularly and rebalanced on an as-needed basis. Plan assets are invested using a combination of active and passive investment strategies. Passive, or “indexed” strategies, attempt to mimic rather than exceed the investment performance of a market benchmark. The plans’ active investment strategies employ multiple investment management firms which in aggregate cover a range of investment styles and approaches. Performance is monitored and compared to relevant benchmarks on a regular basis.
 
The U.S. pension plans consist of
two
plans: a pension plan and a supplemental executive retirement plan (“SERP”). There were
no
assets in the SERP in
2018
and
2017.
Consequently, all of the data disclosed in the asset allocation table for the U.S. pension plans pertain to our U.S. pension plan.
 
During
2018,
we maintained our assets within the allowed ranges of the target asset allocation mix of
60
percent equities and
40
percent fixed income plus or minus
5
percent and continued our focus to reduce volatility of plan assets in future periods and to more closely match the duration of the assets with the duration of the liabilities of the plan. We plan to maintain the portfolio at this target allocation in
2019.
 
The non-U.S. pension plans consist of all the pension plans administered by us outside the U.S., principally consisting of plans in Germany, the United Kingdom, France and Canada. During
2018
we maintained our assets for the non-U.S. pension plans at the specific target asset allocation mix determined for each plan plus or minus the allowed rate and continued our focus to reduce volatility of plan assets in future periods and to more closely match the duration of the assets with the duration of the liabilities of the individual plans. We plan to maintain the portfolios at their respective target asset allocations in
2019.
 
Other postretirement benefits plans consist of
two
U.S. plans: a retiree medical health care plan and a group term life insurance plan. There were
no
assets in the group term life insurance plan for
2018
and
2017.
Consequently, all of the data disclosed in the asset allocation table for other postretirement plans pertain to our retiree medical health care plan. Our investment strategy for other postretirement benefit plans is to own insurance policies that maintain an asset allocation nearly completely in equities. These equities are invested in a passive portfolio indexed to the S&P
500.
Our large weighting to equities in these plans is driven by the investment options available and the relative underfunded status of the plans.

Fair Value Measurement, certain investments that are measured at NAV (Net Asset Value per share) (or its equivalent) practical expedient have
not
been classified in the fair value hierarchy. The fair value amounts represented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the statement of financial position.
 
The definitions of fair values of our pension and other postretirement benefit plan assets at
December 1, 2018
and
December 2, 2017
by asset category are as follows:
 
Equities
—Primarily publicly traded common stock for purposes of total return and to maintain equity exposure consistent with policy allocations. Investments include: (i) U.S. and non-U.S. equity securities and mutual funds valued at closing prices from national exchanges; and (ii) commingled funds valued at unit values or net asset values provided by the investment managers, which are based on the fair value of the underlying investments. Funds valued at net asset value have various investment strategies including seeking maximum total returns consistent with prudent investment management, seeking current income consistent with preservation of capital and daily liquidity and seeking to approximate the risk and return characterized by a specific index fund. There are
no
restrictions for redeeming holdings out of these funds and the funds have
no
unfunded commitments.
 
Fixed income
—Primarily corporate and government debt securities for purposes of total return and managing fixed income exposure to policy allocations. Investments include (i) mutual funds valued at closing prices from national exchanges, (ii) corporate and government debt securities valued at closing prices from national exchanges, (iii) commingled funds valued at unit values or net asset value provided by the investment managers, which are based on the fair value of the underlying investments, and (iv) an annuity contract, the value of which is determined by the provider and represents the amount the plan would receive if the contract were cashed out at year-end.
 
Insurance
—Insurance contracts for purposes of funding postretirement medical benefits. Fair values are the cash surrender values as determined by the providers which are the amounts the plans would receive if the contracts were cashed out at year end.
 
Cash
Cash balances on hand, accrued income and pending settlements of transactions for purposes of handling plan payments. Fair values are the cash balances as reported by the Trustees of the plans.
