EMPLOYEE BENEFIT PLANS

Pension plans. The Company has several non-contributory defined benefit retirement plans covering eligible employees. Plan assets are invested in a diversified portfolio of securities including stocks, bonds, cash equivalents and other alternative investments including real estate investment trust funds. Benefits payable under the plans are based on years of service, final average compensation, or both. The Company retains the right to amend, curtail or discontinue any aspect of the plans, subject to local regulations.

Postretirement plans. The Company maintains plans that provide postretirement benefits to eligible employees, principally health care, to substantially all U.S. retirees and their qualified dependents. These plans were established with the intention that they would continue indefinitely. However, the Company retains the right to amend, curtail or discontinue any aspect of the plans at any time. The plans are contributory and contain certain cost-sharing features, such as deductibles and coinsurance. The Company's policy is to fund postretirement benefits as claims and premiums are paid.

The following tables summarize activity of the Company's defined benefit pension plans and postretirement benefit plans:

_____________


(1)	The decrease in interest cost is primarily due to the election made at the end of 2015 to adopt the spot-rate approach to determine the interest cost component of pension and postretirement expense.

(2)

Actuarial losses in 2016 in the Company's pension benefit plans resulted from changes in discount rate assumptions. Actuarial gains in 2015 in the Company's pension benefit plans resulted from changes in mortality and discount rate assumptions, primarily for the Company's U.S. plans. Changes in financial markets during 2016 and 2015, including a decrease and increase, respectively, in corporate bond yield indices, resulted in an increase and decrease in benefit obligations, respectively.


(3)	The decrease in pension plan settlements in 2016 was primarily due to 2015 settlement activity that continued to reflect impacts from restructuring.


(4)	The increase in return on plan assets in 2016 was primarily due to better-than-expected asset performance, as compared to the poor investment performance in 2015, of U.S. and international equity securities.

Amounts recognized in the Company's consolidated balance sheets as of November 27, 2016, and November 29, 2015, consist of the following:

(1)	The decrease in interest cost is primarily due to the election made at the end of 2015 to adopt the spot-rate approach to determine the interest cost component of pension and postretirement expense.

The amounts that will be amortized from "Accumulated other comprehensive loss" into net periodic benefit cost in 2017 for the Company's defined benefit pension and postretirement benefit plans are expected to be $13.4 million and $1.3 million, respectively.

Assumptions used in accounting for the Company's benefit plans were as follows:



	Pension Benefits			Postretirement Benefits
	2016	2015	2014	2016	2015	2014
Weighted-average assumptions used to determine net periodic benefit cost:
Discount rate	4.0%	3.8%	4.6%	3.8%	3.6%	4.2%
Expected long-term rate of return on plan assets	5.9%	5.9%	6.3%
Rate of compensation increase	3.4%	3.4%	3.7%

Weighted-average assumptions used to determine benefit obligations:
Discount rate	3.8%	4.0%	3.8%	3.7%	3.8%	3.6%
Rate of compensation increase	3.4%	3.4%	3.4%

Assumed health care cost trend rates were as follows:
Health care trend rate assumed for next year				6.4%	6.4%	7.0%
Rate trend to which the cost trend is assumed to decline				4.4%	4.4%	4.5%
Year that rate reaches the ultimate trend rate				2038	2038	2028

For the Company's U.S. benefit plans, the discount rate used to determine the present value of the future pension and postretirement plan obligations was based on a yield curve constructed from a portfolio of high quality corporate bonds with various maturities. Each year's expected future benefit payments are discounted to their present value at the appropriate yield curve rate, thereby generating the overall discount rate. The Company utilized a variety of country-specific third-party bond indices to determine the appropriate discount rates to use for the benefit plans of its foreign subsidiaries.

The Company bases the overall expected long-term rate of return on assets on anticipated long-term returns of individual asset classes and each pension plans' target asset allocation strategy based on current economic conditions. For the U.S. pension plan, the expected long-term returns for each asset class are determined through a mean-variance model to estimate 20-year returns for the plan.

Health care cost trend rate assumptions are not a significant input in the calculation of the amounts reported for the Company's postretirement benefits plans. A one percentage-point change in assumed health care cost trend rates would have no significant effect on the total service and interest cost components or on the postretirement benefit obligation.

Consolidated pension plan assets relate primarily to the U.S. pension plan. The Company utilizes the services of independent third-party investment managers to oversee the management of U.S. pension plan assets. The Company's investment strategy is to invest plan assets in a diversified portfolio of domestic and international equity securities, fixed income securities and real estate and other alternative investments with the objective of generating long-term growth in plan assets at a reasonable level of risk. Prohibited investments for the U.S. pension plan include certain privately placed or other non-marketable debt instruments, letter stock, commodities or commodity contracts and derivatives of mortgage-backed securities, such as interest-only, principal-only or inverse floaters. The current target allocation percentages for the Company's U.S. pension plan assets are 40-44% for equity securities, 48-52% for fixed income securities and 6-10% for other alternative investments, including real estate.

The fair value of the Company's pension plan assets by asset class are as follows:
