Pension and Postretirement Benefits

Pension Benefits — We sponsor a number of noncontributory defined benefit pension plans to provide retirement benefits to all eligible U.S. and non-U.S. employees. The benefits provided under these plans are based primarily on years of service and compensation levels. In 1999, we implemented significant amendments to certain U.S. pension plans. Under a new formula, retirement benefits are determined based on percentages of annual pay and age. To minimize the impact of converting to the new formula, service and earnings credit continues to accrue through the year 2015 for active employees participating in the plans under the old formula prior to the amendments. Employees will receive the benefit from either the new or old formula, whichever is higher. Benefits become vested upon the completion of three years of service. Benefits are paid from funds previously provided to trustees and insurance companies or are paid directly by us from general funds. Effective as of January 1, 2011, our U.S. pension plans were amended so that employees hired or rehired on or after that date and who are not covered by collective bargaining agreements will not be eligible to participate in the plans.

Postretirement Benefits — We provide postretirement benefits, including health care and life insurance, to substantially all retired U.S. employees and their dependents. We established retiree medical account benefits for eligible U.S. retirees. The accounts were intended to provide reimbursement for eligible health care expenses on a tax-favored basis. Effective as of January 1, 2011, the retirement medical program was amended to eliminate the retiree medical account benefit for employees not covered by collective bargaining agreements. To preserve the benefit for employees close to retirement age, the retiree medical account will be available to employees who were at least age 50 with at least 10 years of service as of December 31, 2010, and who satisfy the other eligibility requirements for the retiree medical program.

We use the fiscal year end as the measurement date for the benefit plans.

Components of benefit expense were as follows:



	Pension
	2015			2014			2013
Service cost	$	28		$	42		$	57
Interest cost	105			115			108
Expected return on plan assets	(173		)	(176		)	(177		)
Amortization of prior service credit	(1		)	(1		)	(1		)
Recognized net actuarial loss	84			76			108
Curtailment loss	1			—			3
Settlement charges	—			22			—
Net periodic benefit expense	$	44		$	78		$	98

The curtailment loss of $1 in 2015 was related to a voluntary employee separation program and was included in Restructuring charges. See also Note 8. The settlement charges of $22 in 2014 were associated with a U.S. pension plan. The settlements resulted from the level of lump sum distributions from the plan's assets in 2014, primarily due to the closure of the facility in Sacramento, California. The curtailment loss of $3 in 2013 related to the closure of the plant in Mexico and was included in the Restructuring charges. See also Note 8. In 2013, net periodic benefit expense of $1 related to the simple meals business in Europe and was included in Earnings (loss) from discontinued operations.

The estimated prior service credit and net actuarial losses that will be amortized from Accumulated other comprehensive loss into periodic pension cost during 2016 are $1 and $90, respectively.



	Postretirement
	2015			2014			2013
Service cost	$	2		$	2		$	3
Interest cost	15			17			15
Amortization of prior service credit	(1		)	(1		)	(1		)
Recognized net actuarial loss	14			13			15
Curtailment loss	6			—			—
Net periodic benefit expense	$	36		$	31		$	32

The curtailment loss of $6 in 2015 was related to a voluntary employee separation program and was included in Restructuring charges. See also Note 8.

The estimated prior service credit and net actuarial loss that will be amortized from Accumulated other comprehensive loss into net periodic postretirement expense during 2016 are $1 and $13, respectively.

Prior service credit	(1		)	(2		)	(4		)	(5		)
Total	$	1,050		$	1,017		$	86		$	91

The changes in other comprehensive loss associated with pension benefits included the reclassification of actuarial losses into earnings of $84 and $100 in 2015 and 2014, respectively. The remaining changes in other comprehensive loss associated with pension benefits were primarily due to net actuarial losses arising during the periods as well as the impact of currency. The amount reclassified in 2014 included the settlement charges and $2 of net actuarial losses recognized in discontinued operations as a result of the sale of the European simple meals business.

The change in other comprehensive loss associated with postretirement benefits was due to the reclassification of actuarial losses into earnings of $14 and $13 in 2015 and 2014, respectively. The remaining changes in other comprehensive loss associated with postretirement benefits were primarily due to net actuarial losses arising during the periods.

The following table provides information for pension plans with accumulated benefit obligations in excess of plan assets:



	2015		2014
Projected benefit obligation	$	1,926	$	269
Accumulated benefit obligation	$	1,906	$	257
Fair value of plan assets	$	1,684	$	92

The accumulated benefit obligation for all pension plans was $2,516 at August 2, 2015, and $2,477 at August 3, 2014.

Weighted-average assumptions used to determine benefit obligations at the end of the year:



	Pension		Postretirement
	2015	2014	2015	2014
Discount rate	4.19%	4.33%	4.00%	4.00%
Rate of compensation increase	3.29%	3.30%	3.25%	3.25%

Weighted-average assumptions used to determine net periodic benefit cost for the years ended:



	Pension
	2015	2014	2013
Discount rate	4.33%	4.82%	4.05%
Expected return on plan assets	7.62%	7.62%	7.65%
Rate of compensation increase	3.30%	3.30%	3.31%

The discount rate is established as of our fiscal year-end measurement date. In establishing the discount rate, we review published market indices of high-quality debt securities, adjusted as appropriate for duration. In addition, independent actuaries apply high-quality bond yield curves to the expected benefit payments of the plans. The expected return on plan assets is a long-term assumption based upon historical experience and expected future performance, considering our current and projected investment mix. This estimate is based on an estimate of future inflation, long-term projected real returns for each asset class, and a premium for active management.

The discount rate used to determine net periodic postretirement expense was 4.00% in 2015, 4.50% in 2014 and 3.75% in 2013.

Assumed health care cost trend rates at the end of the year:



	2015	2014
Health care cost trend rate assumed for next year	7.75%	8.25%
Rate to which the cost trend rate is assumed to decline (ultimate trend rate)	4.50%	4.50%
Year that the rate reaches the ultimate trend rate	2022	2022

A one-percentage-point change in assumed health care costs would have the following effects on 2015 reported amounts:



	Increase		Decrease
Effect on service and interest cost	$	1	$	(1	)
Effect on the 2015 accumulated benefit obligation	$	25	$	(22	)

Pension Plan Assets

The fundamental goal underlying the investment policy is to ensure that the assets of the plans are invested in a prudent manner to meet the obligations of the plans as these obligations come due. The primary investment objectives include providing a total return which will promote the goal of benefit security by attaining an appropriate ratio of plan assets to plan obligations, to provide for real asset growth while also tracking plan obligations, to diversify investments across and within asset classes, to reduce the impact of losses in single investments, and to follow investment practices that comply with applicable laws and regulations.

The primary policy objectives will be met by investing assets to achieve a reasonable tradeoff between return and risk relative to plan obligations. This includes investing a portion of the assets in funds selected in part to hedge the interest rate sensitivity to plan obligations.

The portfolio includes investments in the following asset classes: fixed income, equity, real estate and alternatives. Fixed income will provide a moderate expected return and partially hedge the exposure to interest rate risk of the plans’ obligations. Equities are used for their high expected return. Additional asset classes are used to provide diversification.

Asset allocation is monitored on an ongoing basis relative to the established asset class targets. The interaction between plan assets and benefit obligations is periodically studied to assist in the establishment of strategic asset allocation targets. The investment policy permits variances from the targets within certain parameters. Asset rebalancing occurs when the underlying asset class allocations move outside these parameters, at which time the asset allocation is rebalanced back to the policy target weight.

Our year-end pension plan weighted-average asset allocations by category were:



	Strategic Target	2015	2014
Equity securities	51%	50%	51%
Debt securities	35%	34%	33%
Real estate and other	14%	16%	16%
Net periodic benefit expense	100%	100%	100%

Pension plan assets are categorized based on the following fair value hierarchy:


•	Level 1: Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.


•	Level 2: Inputs other than quoted prices included in Level 1 that are observable for the asset or liability through corroboration with observable market data.


•	Level 3: Unobservable inputs, which are valued based on our estimates of assumptions that market participants would use in pricing the asset or liability.

The following table presents our pension plan assets by asset category at August 2, 2015, and August 3, 2014:

Short-term investments — Investments include cash and cash equivalents, and various short-term debt instruments and short-term investment funds. Institutional short-term investment vehicles valued daily are classified as Level 1 at cost which approximates market value. Other investments valued based upon a quoted net asset value are included as a reconciling item to the fair value table.

Equities — Common stocks and preferred stocks are classified as Level 1 and are valued using quoted market prices in active markets.

Corporate bonds — These investments are valued based on quoted market prices, yield curves and pricing models using current market rates.

Government and agency bonds — These investments are generally valued based on bid quotations and recent trade data for identical or similar obligations.

Municipal bonds — These investments are valued based on quoted market prices, yield curves and pricing models using current market rates.

Mortgage and asset backed securities — Fair value is based on prices obtained from third party pricing sources. The prices from third party pricing sources may be based on bid quotes from dealers and recent trade data. Mortgage backed securities are traded in the over-the-counter market.

Real estate — Real estate investments consist of real estate investment trusts, property funds and limited partnerships. Real estate investment trusts are classified as Level 1 and are valued based on quoted market prices. Property funds are classified as either Level 2 or Level 3 depending upon whether liquidity is limited or there are few observable market participant transactions. Fair value is based on third party appraisals. Limited partnerships are valued based upon valuations provided by the general partners of the funds. The values of limited partnerships are based upon an assessment of each underlying investment, incorporating valuations that consider the evaluation of financing and sales transactions with third parties, expected cash flows, and market-based information, including comparable transactions and performance multiples among other factors. The investments are classified as Level 3 since the valuation is determined using unobservable inputs. Real estate investments valued at net asset value are included as a reconciling item to the fair value table.

Hedge funds — Hedge fund investments include hedge funds valued based upon a net asset value derived from the fair value of underlying securities. Hedge fund investments that are subject to liquidity restrictions or that are based on unobservable inputs are classified as Level 3. Hedge fund investments may include long and short positions in equity and fixed income securities, derivative instruments such as futures and options, commodities and other types of securities. Hedge fund investments valued at net asset value are included as a reconciling item to the fair value table.

Derivatives — Derivative financial instruments include forward currency contracts, futures contracts, options contracts, interest rate swaps and credit default swaps. Derivative financial instruments are classified as Level 2 and are valued based on observable market transactions or prices.

Commingled funds — Investments in commingled funds are not traded in active markets. Blended commingled funds are invested in both equities and fixed income securities. Commingled funds are valued based on the net asset values of such funds. and are included as a reconciling item to the fair value table.

Other items to reconcile to fair value of plan assets included amounts due for securities sold, amounts payable for securities purchased, and other payables.

Savings Plan — We sponsor employee savings plans that cover substantially all U.S. employees. Effective January 1, 2011, we provide a matching contribution of 100% of employee contributions up to 4% of compensation for employees who are not covered by collective bargaining agreements. Employees hired or rehired on or after January 1, 2011 who will not be eligible to participate in the defined benefit plans and who are not covered by collective bargaining agreements receive a contribution equal to 3% of compensation regardless of their participation in the Savings Plan. Prior to January 1, 2011, we provided a matching contribution of 60% (50% at certain locations) of the employee contributions up to 5% of compensation after one year of continued service. Amounts charged to Costs and expenses were $31 in 2015, $29 in 2014 and $27 in 2013.
