The Company sponsors various qualified and non-qualified defined benefit pension and other postretirement benefit plans that provide for retirement and medical benefits for substantially all employees residing in the United States. The Company uses a September 30 measurement date for its pension and other postretirement benefit plans.

Defined benefit pension plans. The defined benefit pension plan benefits are based on years of service, age and eligible compensation. Prior to January 1, 2011, employees hired before January 1, 2008 earned benefits based on their pay during their last five years of employment. Employees hired or rehired on or after January 1, 2008, earned benefits based on a cash balance formula. Effective January 1, 2011, all employees began accruing benefits under the cash balance formula and ceased accruing benefits under any other formula. An employee’s cash balance account is credited with an amount equal to 6% of eligible compensation plus interest based on 30-year Treasury securities. The funding policy is to contribute annually no less than the minimum required contribution under ERISA.

Postretirement benefits plan. The postretirement benefits plan provides medical benefits for retirees and dependents who meet minimum age and service requirements. Benefits are provided from retirement date until age 65. Retirees must contribute on a monthly basis for the same coverage that is generally available to active employees and their dependents. The Company’s contributions are funded on a current basis.

Weighted Average Actuarial Assumptions:



	Fiscal
	2013		2012		2011
Discount rate for benefit obligation:⁽¹⁾
Pension	4.81	%	3.85	%	4.70	%
Postretirement	2.76	%	2.21	%	3.39	%
Discount rate for net periodic benefit cost:
Pension	3.85	%	4.70	%	5.25	%
Postretirement	2.21	%	3.39	%	3.45	%
Expected long-term rate of return on plan assets⁽²⁾	7.00	%	7.50	%	7.50	%
Rate of increase in compensation levels for:
Benefit obligation	4.50	%	4.50	%	4.50	%
Net periodic benefit cost	4.50	%	4.50	%	4.50	%


⁽¹⁾	Based on a “bond duration matching” methodology, which reflects the matching of projected plan liability cash flows to an average of high-quality corporate bond yield curves whose duration matches the projected cash flows.


⁽²⁾	Primarily based on the targeted allocation, and evaluated for reasonableness by considering such factors as: (i) actual return on plan assets; (ii) historical rates of return on various asset classes in the portfolio; (iii) projections of returns on various asset classes; and (iv) current and prospective capital market conditions and economic forecasts.

The assumed annual rate of future increases in health benefits for the other postretirement benefits plan is 8.5% for fiscal 2014. The rate is assumed to decrease to 5% by 2020 and remain at that level thereafter. These trend rates reflect management’s expectations of future rates. Increasing or decreasing the healthcare cost trend by 1% would change the postretirement plan benefit obligation by less than $1 million.

Pension Plan Assets

Pension plan assets are managed with a long-term perspective to ensure that there is an adequate level of assets to support benefit payments to participants over the life of the pension plan. Pension plan assets are managed by external investment managers. Investment manager performance is measured against benchmarks for each asset class on a quarterly basis. An independent consultant assists management with investment manager selections and performance evaluations.

Pension plan assets are broadly diversified to maintain a prudent level of risk and to provide adequate liquidity for benefit payments. The Company generally evaluates and rebalances the pension plan assets, as appropriate, to ensure that allocations are consistent with target allocation ranges. The current target allocation for pension plan assets is as follows: equity securities of 50% to 80%, fixed income securities of 25% to 35% and other, primarily consisting of cash to meet near term expected benefit payments and expenses, of up to 7%. At September 30, 2013, pension plan asset allocations for the above categories were 71%, 26% and 3%, respectively, which were within target allocation ranges.

The following table sets forth by level, within the fair value hierarchy, the pension plan’s investments at fair value as of September 30, 2013 and 2012, including the impact of unsettled transactions:



	Fair Value Measurements at September 30,
	Level 1				Level 2				Level 3				Total
	2013		2012		2013		2012		2013		2012		2013		2012
	(in millions)
Cash equivalents	$	26	$	79									$	26	$	79
Collective investment funds					$	—	$	391					—		391
Corporate debt securities					106		115						106		115
Debt securities of U.S. Treasury and federal agencies					149		121						149		121
Asset-backed securities									$	23	$	25	23		25
Equity securities	751		242										751		242
Total	$	777	$	321	$	255	$	627	$	23	$	25	$	1,055	$	973

Level 1 assets. Cash equivalents (money market funds) and equity securities are classified as Level 1 within the fair value hierarchy, as fair value is based on quoted prices in active markets.

Level 2 assets. The fair values of government-sponsored and corporate debt securities are based on quoted prices in active markets for similar assets as provided by third-party pricing vendors. This pricing data is reviewed internally for reasonableness through comparisons with benchmark quotes from independent third-party sources. Based on this review, the valuation is confirmed or revised accordingly. Collective investment funds are unregistered investment vehicles that commingle the assets of multiple fiduciary clients, such as pension and other employee benefits plans, to invest in portfolios of stocks, bonds or other securities. A single collective investment fund, previously held by the pension plan, was ultimately invested in common stocks of companies in the S&P 500 index, and as its own unit value was not directly observable, it was therefore classified as Level 2.

Level 3 assets. Asset-backed securities are bonds that are backed by various types of assets and primarily consist of mortgage-backed securities. Asset-backed securities are classified as Level 3 due to a lack of observable inputs in measuring fair value.

There were no transfers between Level 1 and Level 2 assets during fiscal 2013 or 2012. A separate roll-forward of Level 3 plan assets measured at fair value is not presented because activities during fiscal 2013 and 2012 were immaterial.

Cash Flows



	Pension Benefits		Other Postretirement Benefits
Actual employer contributions	(in millions)
2013	$	—	$	4
2012	$	84	$	4
Expected employer contributions
2014	$	8	$	4

2018	$	96	$	3
2019-2023	$	413	$	10

The lower contribution to pension benefits in fiscal 2013 was driven by a higher-than-expected rate of return on the Company's plan assets during the year and an increase in the discount rate at September 30, 2013 compared to September 30, 2012.

Other Benefits

The Company sponsors a defined contribution plan, or 401(k) plan, that covers substantially all of its employees residing in the United States. Personnel costs included $44 million, $37 million and $34 million in fiscal 2013, 2012 and 2011, respectively, for expenses attributable to the Company’s employees under the 401(k) plan. The Company’s contributions to this 401(k) plan are funded on a current basis, and the related expenses are recognized in the period that the payroll expenses are incurred.
