Schedule of Economic Assumptions

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

	Pension Benefits						Other Benefits
	2014		2013		2012		2014		2013		2012
Benefit obligation:
Discount rate	4.22	%	4.95	%	4.22	%	4.22	%	4.95	%	4.22	%
Net pension and other postretirement cost:
Discount rate	4.95	%	4.22	%	5.09	%	4.95	%	4.22	%	5.09	%
Rate of compensation increase	NA		NA		3.00	%	NA		NA		NA
Expected return on plan assets	6.00	%	6.00	%	7.50	%	NA		NA		NA

Schedule of Plan Asset Allocations

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

	2014		2013
Cash and cash equivalents	—	%	—	%
Pooled separate accounts(a):
Equity securities	6	%	8	%
Fixed income securities	6	%	3	%
Common collective trust funds(a):
Equity securities	60	%	60	%
Fixed income securities	28	%	29	%
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 Securities and Exchange Commission. 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 Assumptions of Plan Assets

The fair value measurements of plan assets fell into the following levels of the fair value hierarchy as of December 28, 2014 and December 29, 2013:

	2014								2013(a)
	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	$	33	$	—	$	—	$	33	$	275	$	—	$	—	$	275
Pooled separate accounts:
Large U.S. equity funds(d)	—		4,147		—		4,147		—		4,828		—		4,828
Small/Mid U.S. equity funds(e)	—		1,062		—		1,062		—		1,192		—		1,192
International equity funds(f)	—		1,719		—		1,719		—		2,019		—		2,019
Fixed income funds(g)	—		6,609		—		6,609		—		3,442		—		3,442
Common collective trusts funds:
Large U.S. equity funds(d)	—		29,964		—		29,964		—		28,784		—		28,784
Small U.S. equity funds(e)	—		18,411		—		18,411		—		16,937		—		16,937
International equity funds(f)	—		19,730		—		19,730		—		19,420		—		19,420
Fixed income funds(g)	—		31,877		—		31,877		—		31,599		—		31,599
Total assets	$	33	$	113,519	$	—	$	113,552	$	275	$	108,221	$	—	$	108,496

(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 December 28, 2014 expected to be paid in each of the next five years and in the aggregate for the five years thereafter 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.
