Schedule of Economic Assumptions, and Impact of Change in Discount Rate on Benefit Obligation

The sensitivity of the projected benefit obligation for pension benefits to changes in the discount rate is set out below. The impact of a change in the discount rate of 0.25% on the projected benefit obligation for other benefits is less than $1,000. This sensitivity analysis is based on changing one assumption while holding all other assumptions constant. In practice, this is unlikely to occur, and changes in some of the assumptions may be correlated. When calculating the sensitivity of the defined benefit obligation to variations in significant actuarial assumptions, the same method (present value of the defined benefit obligation calculated with the projected unit credit method at the end of the reporting period) has been applied as for calculating the liability recognized in the Condensed Consolidated Balance Sheet.

	Increase in Discount Rate of 0.25%			Decrease in Discount Rate of 0.25%
	(In thousands)
Impact on projected benefit obligation for pension benefits	$	(4,617	)	$	4,909

The weighted average assumptions used in determining pension and other postretirement plan information were as follows:

	March 26, 2017				December 25, 2016
	Pension Benefits		Other Benefits		Pension Benefits		Other Benefits
Assumptions used to measure benefit obligation at end of period:
Discount rate	4.29	%	3.78	%	4.31	%	3.81	%

	Thirteen Weeks Ended   March 26, 2017				Thirteen Weeks Ended   March 27, 2016
	Pension Benefits		Other Benefits		Pension Benefits		Other Benefits
Assumptions used to measure net pension and other postretirement cost:
Discount rate	4.31	%	3.81	%	4.47	%	4.47	%
Expected return on plan assets	5.50	%	NA		5.50	%	NA

Schedule of Plan Asset Allocations

The following table reflects the pension plans’ actual asset allocations:

	March 26, 2017		December 25, 2016
Cash and cash equivalents	—	%	—	%
Pooled separate accounts(a):
Equity securities	5	%	5	%
Fixed income securities	5	%	5	%
Common collective trust funds(a):
Equity securities	60	%	60	%
Fixed income securities	30	%	30	%
Total assets	100	%	100	%

(a) Pooled separate accounts (“PSAs”) and common collective trust funds (“CCTs”) are two of the most common types of alternative vehicles in which benefit plans invest. These investments are pooled funds that look like mutual funds, but they are not registered with the SEC. Often times, they will be invested in mutual funds or other marketable securities, but the unit price generally will be different from the value of the underlying securities because the fund may also hold cash for liquidity purposes, and the fees imposed by the fund are deducted from the fund value rather than charged separately to investors. Some PSAs and CCTs have no restrictions as to their investment strategy and can invest in riskier investments, such as derivatives, hedge funds, private equity funds, or similar investments.

Schedule of Fair Value Measurements of Plan Assets

The fair value measurements of plan assets fell into the following levels of the fair value hierarchy as of March 26, 2017 and December 25, 2016:

	March 26, 2017								December 25, 2016
	Level 1(a)		Level 2(b)		Level 3(c)		Total		Level 1(a)		Level 2(b)		Level 3(c)		Total
	(In thousands)
Cash and cash equivalents	$	140	$	—	$	—	$	140	$	119	$	—	$	—	$	119
Pooled separate accounts:
Large U.S. equity funds(d)	—		3,456		—		3,456		—		3,302		—		3,302
Small/Mid U.S. equity funds(e)	—		409		—		409		—		406		—		406
International equity funds(f)	—		1,349		—		1,349		—		1,231		—		1,231
Fixed income funds(g)	—		4,828		—		4,828		—		4,867		—		4,867
Common collective trusts funds:
Large U.S. equity funds(d)	—		24,785		—		24,785		—		24,547		—		24,547
Small U.S. equity funds(e)	—		17,080		—		17,080		—		17,344		—		17,344
International equity funds(f)	—		18,784		—		18,784		—		17,006		—		17,006
Fixed income funds(g)	—		30,349		—		30,349		—		28,704		—		28,704
Total assets	$	140	$	101,040	$	—	$	101,180	$	119	$	97,407	$	—	$	97,526

(a) Unadjusted quoted prices in active markets for identical assets are used to determine fair value.

(b) Quoted prices in active markets for similar assets and inputs that are observable for the asset are used to determine fair value.

(c) Unobservable inputs, such as discounted cash flow models or valuations, are used to determine fair value.

(d) This category is comprised of investment options that invest in stocks, or shares of ownership, in large, well-established U.S. companies. These investment options typically carry more risk than fixed income options but have the potential for higher returns over longer time periods.

(e) This category is generally comprised of investment options that invest in stocks, or shares of ownership, in small to medium-sized U.S. companies. These investment options typically carry more risk than larger U.S. equity investment options but have the potential for higher returns.

(f) This category is comprised of investment options that invest in stocks, or shares of ownership, in companies with their principal place of business or office outside of the U.S.

(g) This category is comprised of investment options that invest in bonds, or debt of a company or government entity (including U.S. and non-U.S. entities). It may also include real estate investment options that directly own property. These investment options typically carry more risk than short-term fixed income investment options (including, for real estate investment options, liquidity risk), but less overall risk than equities.

Schedule of Benefit Payments

The following table reflects the benefits as of March 26, 2017 expected to be paid through 2026 from our pension and other postretirement plans. Because our pension plans are primarily funded plans, the anticipated benefits with respect to these plans will come primarily from the trusts established for these plans. Because our other postretirement plans are unfunded, the anticipated benefits with respect to these plans will come from our own assets.
