Benefit Plans [Abstract] |
Benefit Plans | 10.Benefit Plans (A) Retirement Benefit Plans Effective December 31, 2008, we froze both of our noncontributory defined benefit plans: our pension plan (the “pension plan”) and our unfunded, nonqualified plan (the “restoration plan”), which restores retirement benefits for certain associates who are affected by Internal Revenue Code limitations on benefits provided under the pension plan. No additional benefits have accrued under these plans since that date. In connection with benefits earned prior to December 31, 2008, we have a continuing obligation to fund the pension plan and will continue to recognize net periodic pension expense for both plans. We use a fiscal year end measurement date for both the pension plan and the restoration plan. Benefit Plan Information

Benefit Obligations. Accumulated and projected benefit obligations (“ABO” and “PBO”) represent the obligations of the benefit plans for past service as of the measurement date. ABO is the present value of benefits earned to date with benefits computed based on current service and compensation levels. PBO is ABO increased to reflect expected future service and increased compensation levels. As a result of the freeze of plan benefits under our pension and restoration plans as of December 31, 2008, the ABO and PBO balances are equal to one another at all subsequent dates.

(2)Consists of equity securities of primarily foreign corporations from diverse industries including bank, pharmaceutical, telecommunication, oil and gas, insurance and food sectors; 100% of securities relate to non-U.S. entities as of February 28, 2014 (100% relate to non-U.S. entities, as of February 28, 2013). (3)Includes debt securities of U.S. and foreign governments, their agencies and corporations, and diverse investments in mortgage-backed securities and banks; approximately 90% of securities relate to U.S. entities and 1 0% of securities relate to non-U.S. entities as of February 28, 2014 (85% and 15%, respectively, as of February 28, 2013). (4)Includes pooled funds representing short-term instruments that include governments, their agencies and corporations and large-, mid- and small-cap companies primarily from the U.S. bank sector; nearly 100% of securities relate to U.S. entities as of February 28, 2014 (nearly 100% as of February 28, 2013). Plan Assets. Our pension plan assets are held in trust and management sets the investment policies and strategies. Long-term strategic investment objectives include asset preservation and appropriately balancing risk and return. We oversee the investment allocation process, which includes selecting investment managers, setting long-term strategic targets and monitoring asset allocations and performance. Target allocations for plan assets are guidelines, not limitations, and occasionally plan fiduciaries may approve allocations above or below the targets. We target allocating 75% of plan assets to equity and equity-related instruments and 25% to fixed income securities. Equity securities are currently composed of mutual funds that include highly diversified investments in large-, mid- and small-cap companies located in the United States and internationally. The fixed income securities are currently composed of mutual funds that include investments in debt securities, mortgage-backed securities, corporate bonds and other debt obligations primarily in the United States. We do not expect any plan assets to be returned to us during fiscal 2015. Plan assets also include collective funds, which are public investment vehicles with the underlying assets representing high quality, short-term instruments that include securities of governments, their agencies and corporations and large, mid, and small cap companies located in the United States and internationally. The fair values of the plan’s assets are provided by the plan’s trustee and the investment managers. Within the fair value hierarchy (see Note 6), the mutual funds are classified as Level 1 as quoted active market prices for identical assets are used to measure fair value. The collective funds are public investment vehicles valued using a net asset value (“NAV”) provided by the plan’s trustee as a practical expedient for measuring the fair value. The NAV is based on the underlying net assets owned by the fund divided by the number of shares outstanding. The NAV’s unit price is quoted on a private market that was not active. However, the NAV is based on the fair value of the underlying securities within the fund, which were traded on an active market and valued at the closing price reported on the active market on which those individual securities are traded. The collective funds may be liquidated with minimal restrictions and are classified as Level 2. Funding Policy. For the pension plan, we contribute amounts sufficient to meet minimum funding requirements as set forth in the employee benefit and tax laws, plus any additional amounts as we may determine to be appropriate. We expect to contribute $4.2 million to the pension plan in fiscal 201 5. For the non-funded restoration plan, we contribute an amount equal to the benefit payments. Estimated Future Benefit Payments

In fiscal 201 5, we anticipate that $1.4 million in estimated actuarial losses of the pension plan will be amortized from accumulated other comprehensive loss. We do not anticipate that any appreciable estimated actuarial losses will be amortized from accumulated other comprehensive loss for the restoration plan.

(1)For the restoration plan, the discount rate presented is applied to the pre-2004 annuity amounts. A rate of 4.50% is assumed for post-2004 lump sum amounts paid from the plan for fiscal 2014 and fiscal 2013. For fiscal 2012 and prior years, a rate of 5.00% was assumed for post-2004 lump sum amounts paid from the plan. Assumptions. Underlying both the calculation of the PBO and the net pension expense are actuarial calculations of each plan’s liability. These calculations use participant-specific information such as salary, age and years of service, as well as certain assumptions, the most significant being the discount rate, rate of return on plan assets and mortality rate. We evaluate these assumptions at least once a year and make changes as necessary. The discount rate used for retirement benefit plan accounting reflects the yields available on high-quality, fixed income debt instruments. For our plans, we review high quality corporate bond indices in addition to a hypothetical portfolio of corporate bonds with maturities that approximate the expected timing of the anticipated benefit payments. To determine the expected long-term return on plan assets, we consider the current and anticipated asset allocations, as well as historical and estimated returns on various categories of plan assets. We apply the estimated rate of return to a market-related value of assets, which reduces the underlying variability in the asset values. The use of expected long-term rates of return on pension plan assets could result in recognized asset returns that are greater or less than the actual returns of those pension plan assets in any given year. Over time, however, the expected long-term returns are anticipated to approximate the actual long-term returns, and therefore, result in a pattern of income and expense recognition that more closely matches the pattern of the services provided by the employees. Differences between actual and expected returns, which are a component of unrecognized actuarial gains/losses, are recognized over the average life expectancy of all plan participants. Given the frozen status of the pension and benefit restoration plans, the rate of compensation increases is not applicable for periods subsequent to December 31, 2008. Mortality rate assumptions are based on the life expectancy of the population and were updated in fiscal 2011 to account for increases in life expectancy. (B) Retirement Savings 401(k) Plan We sponsor a 401(k) plan for all associates meeting certain eligibility criteria. In conjunction with the pension plan curtailments, enhancements were made to the 401(k) plan effective January 1, 2009. The enhancements increased the maximum salary contribution for eligible associates and increased our matching contribution. Additionally, an annual company-funded contribution regardless of associate participation was implemented, as well as an additional company-funded contribution to those associates meeting certain age and service requirements. The total cost for company contributions was $25.0 million in fiscal 2014, $23.1 million in fiscal 2013 and $20.9 million in fiscal 2012. (C) Retirement Restoration Plan Effective January 1, 2009, we replaced the frozen restoration plan with a new non-qualified retirement plan for certain senior executives who are affected by Internal Revenue Code limitations on benefits provided under the Retirement Savings 401(k) Plan. Under this plan, these associates may continue to defer portions of their compensation for retirement savings. We match the associates’ contributions at the same rate provided under the 401(k) plan, and also provide the annual company-funded contribution made regardless of associate participation, as well as the additional company-funded contribution to the associates meeting the same age and service requirements. This plan is unfunded with lump sum payments to be made upon the associate’s retirement. The total cost for this plan was $1.1 million in fiscal 201 4, $0.4 million in fiscal 201 3 and $0.5 million in fiscal 201 2. (D) Executive Deferred Compensation Plan Effective January 1, 2011, we established an unfunded nonqualified deferred compensation plan to permit certain eligible key associates to defer receipt of a portion of their compensation to a future date. This plan also includes a restorative company contribution designed to compensate the plan participants for any loss of company contributions under the Retirement Savings 401(k) Plan and the Retirement Restoration Plan due to a reduction in their eligible compensation resulting from deferrals into the Executive Deferred Compensation Plan. The total cost for this plan was $0.6 million in fiscal 201 4, $0.4 million in fiscal 2013 and was not material in fiscal 2012.
