_________________________


(1)	Cash and cash equivalents are comprised of commercial paper, short-term bills and notes, and short-term investment funds, which are valued at quoted prices in active markets for similar securities.


(2)	U.S. equity securities are comprised of investments in common stock of U.S. companies for total return purposes. These investments are valued by the trustee at closing prices from national exchanges on the valuation date.

(3)

International equity securities are comprised of investments in common stock of companies located outside of the U.S for total return purposes. These investments are valued by the trustee at closing prices from national exchanges on the valuation date, or the values are adjusted as a result of market movements following the close of local trading using inputs to models that are observable either directly or indirectly. The portion of these investments that are measured at fair value using the net asset value per share practical expedient (see note 4 below) can be redeemed on a monthly basis.


(4)	Certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been categorized in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the statement of financial position.

(5)

Investment grade fixed income consists of debt obligations either issued by the US government or have a rating of BBB- / Baa or higher assigned by a major credit rating agency. These investments are valued based on unadjusted quoted market prices (Level 1), or based on quoted prices in inactive markets, or whose values are based on models, but the inputs to those models are observable either directly or indirectly (Level 2).


(6)	High yield fixed income consists primarily of debt obligations that have a rating of below BBB- / Baa or lower assigned by a major credit rating agency. These investments are valued based on unadjusted quoted market prices.


(7)	Alternative investments consists primarily of an investment in asset classes other than stocks, bonds, and cash. Alternative investments can include commodities, hedge funds, private equity, managed futures, and derivatives. These investments are valued based on unadjusted quoted market prices and can be redeemed on a bi-monthly basis.


(8)	Real estate is investments in a real estate collective trust for purposes of total return. These investments are valued based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. These investments can be redeemed on a quarterly basis.

Determining The Present Values Of Benefit Obligations And Net Periodic Benefit Costs

In determining the present values of our benefit obligations and net periodic benefit costs as of and for the fiscal years ended October 1, 2017, October 2, 2016 and September 27, 2015, we used the following weighted-average assumptions:



	2017		2016		2015
Assumptions used to determine benefit obligations (1):
Qualified Plan:
Discount rate	3.99	%	3.85	%	4.79	%
Rate of future pay increases	—	%	—	%	3.50	%
SERP:
Discount rate	3.80	%	3.60	%	4.45	%
Rate of future pay increases	3.50	%	3.50	%	3.50	%
Postretirement health plans:
Discount rate	3.82	%	3.64	%	4.47	%
Assumptions used to determine net periodic benefit cost (2):
Qualified Plan:
Discount rate	3.85	%	4.79	%	4.60	%
Long-term rate of return on assets	6.50	%	6.50	%	6.50	%
Rate of future pay increases	—	%	3.50	%	3.50	%

Health Care Cost Trend Rates For Postretirement Health Plans

For measurement purposes, the weighted-average assumed health care cost trend rates for our postretirement health plans were as follows for each fiscal year:



	2017		2016		2015
Healthcare cost trend rate for next year:
Participants under age 65	7.50	%	7.75	%	8.00	%
Participants age 65 or older	7.00	%	7.25	%	7.50	%
Rate to which the cost trend rate is assumed to decline:
Participants under age 65	4.50	%	4.50	%	4.50	%
Participants age 65 or older	4.50	%	4.50	%	4.50	%
Year the rate reaches the ultimate trend rate:
Participants under age 65	2030		2030		2030
Participants age 65 or older	2028		2028		2028

Effect Of Change In The Assumed Health Care Cost Trend Rate

For example, a 1.0% change in the assumed healthcare cost trend rate would have the following effect on the fiscal 2017 net periodic benefit cost and end of year PBO (in thousands):



	1% Point Increase		1% Point Decrease
Total interest and service cost	$	123	$	(105	)
Postretirement benefit obligation	$	2,892	$	(2,482	)
