Compensation and Retirement Disclosure [Abstract] |
Pension and Postretirement Health Care Plans | Pension and Postretirement Health Care Plans We have qualified defined benefit pension plans covering team members who meet age and service requirements, including date of hire in certain circumstances. Effective January 1, 2009, our U.S. qualified defined benefit pension plan was closed to new participants, with limited exceptions. We also have unfunded nonqualified pension plans for team members with qualified plan compensation restrictions. Eligibility for, and the level of, these benefits varies depending on each team members' date of hire, length of service and/or team member compensation. Effective April 1, 2016, we will discontinue the postretirement health care benefits that were offered to team members upon early retirement and prior to Medicare eligibility. This decision resulted in a $58 million reduction in the projected postretirement health care benefit obligation and a $43 million curtailment gain recorded in SG&A during 2015. As of January 30, 2016, we have extinguished the remaining benefit obligation related to this plan.

Assumptions
Benefit Obligation Weighted Average Assumptions |

Discount rate | 4.70 | % | 3.87 | %
Average assumed rate of compensation increase | 3.00 |  | 3.00 |
Net Periodic Benefit Expense Weighted Average Assumptions |
| 2015 |  | 2014 |  | 2013 |
Discount rate | 3.87 | % | 4.77 | % | 4.40 | %
Expected long-term rate of return on plan assets | 7.50 |  | 7.50 |  | 8.00 |
Average assumed rate of compensation increase | 3.00 |  | 3.00 |  | 3.00 |
The weighted average assumptions used to measure net periodic benefit expense each year are the rates as of the beginning of the year (i.e., the prior measurement date). Based on a stable asset allocation, our most recent compound annual rate of return on qualified plans' assets was 8.4 percent, 7.2 percent, 6.8 percent, and 8.5 percent for the 5-year, 10-year, 15-year, and 20-year time periods, respectively. The market-related value of plan assets, which is used in calculating expected return on assets in net periodic benefit cost, is determined each year by adjusting the previous year's value by expected return, benefit payments, and cash contributions. The market-related value is adjusted for asset gains and losses in equal 20 percent adjustments over a five-year period. We review the expected long-term rate of return annually, and revise it as appropriate. Additionally, we monitor the mix of investments in our portfolio to ensure alignment with our long-term strategy to manage pension cost and reduce volatility in our assets. Our expected annualized long-term rate of return assumptions as of January 30, 2016 were 8.0 percent for domestic and international equity securities, 5.0 percent for long-duration debt securities, 8.0 percent for balanced funds, and 9.5 percent for other investments. These estimates are a judgmental matter in which we consider the composition of our asset portfolio, our historical long-term investment performance, and current market conditions. Plan Assets Our asset allocation policy is designed to reduce the long-term cost of funding our pension obligations. The plan invests with both passive and active investment managers depending on the investment's asset class. The plan also seeks to reduce the risk associated with adverse movements in interest rates by employing an interest rate hedging program, which may include the use of interest rate swaps, total return swaps, and other instruments.

(a) | Equity securities include our common stock in amounts substantially less than 1 percent of total plan assets as of January 30, 2016 and January 31, 2015.
(b) | Other assets include private equity, mezzanine and high-yield debt, natural resources and timberland funds, multi-strategy hedge funds, derivative instruments, and a 4 percent allocation to real estate.
In May 2015, the FASB issued ASU No. 2015-07, Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent). ASU 2015-07 amended ASC 820, Fair Value Measurements and Disclosures, to remove the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. The amendment also removes the requirement to make certain disclosures for these investments. We have retrospectively adopted this ASU for the year ended January 30, 2016.

(d) | In accordance with Subtopic 820-10, certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been classified 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.
Position |  | Valuation Technique
Cash and cash equivalents |  | Carrying value approximates fair value.
Government securities and fixed income |  | Valued using matrix pricing models and quoted prices of securities with similar characteristics.
Derivatives |  | Swap derivatives - Valued initially using models calibrated to initial trade price. Subsequent valuations are based on observable inputs to the valuation model (e.g., interest rates and credit spreads). Model inputs are changed only when corroborated by market data. A credit risk adjustment is made on each swap using observable market credit spreads. Option derivatives - Valued at transaction price initially. Subsequent valuations are based on observable inputs to the valuation model (e.g., underlying investments).
Contributions Our obligations to plan participants can be met over time through a combination of company contributions to these plans and earnings on plan assets. In 2015 and 2014, we made discretionary contributions of $200 million and $150 million, respectively, to our qualified defined benefit pension plans. We are not required to make any contributions in 2016. However, depending on investment performance and plan funded status, we may elect to make a contribution.
