Compensation and Retirement Disclosure [Abstract] |
Pension and Postretirement Benefit Plans | Pension and Postretirement Benefit Plans The Company and its subsidiaries sponsor multiple defined benefit plans that cover certain employees. Postretirement benefit plans, other than pensions, provide healthcare benefits for certain eligible employees. Benefits are primarily based on years of service and the employee’s compensation. Pension Plans The Company has both funded and unfunded pension benefit plans. It is the Company’s policy to fund such plans in accordance with applicable laws and regulations in order to ensure adequate funds are available in the plans to make benefit payments to plan participants and beneficiaries when required. The following table details information regarding the Company's pension plans:

During the fourth quarter of 2012, the Company completed the liquidation of two pension plans related to its former Dominion Textile, Inc. business in Canada. All pension benefits legally owed to plan participants were fully paid from plan assets by the end 2012. Excess plan assets left in the trust after all participants were paid was $0.3 million and is reported within Other current assets in the Company's Consolidated Balance Sheet at December 29, 2012. The surplus was received by the Company in the first quarter of 2013. As a result of the liquidation of these plans, the Company recognized a settlement loss of $0.8 million within Special charges, net in the Company's Consolidated Statement of Operations. The expected long-term rate of return on plan assets reflects the average rate of returns expected on the funds invested or to be invested in order to provide for the benefits included in the projected benefit obligation. The expected long-term rate of return on plan assets is based on what is achievable given the plan's investment policy, the types of assets held and target asset allocations. The expected long-term rate of return is determined as of the measurement date. The Company reviews each plan and its historical returns and target asset allocations to determine the appropriate long-term rate of return on plan assets to be used. Discount rates are primarily based on the market yields of global bond indices for AA-rated corporate bonds, applied to a portfolio for which the term and currency correspond with the estimated term and currency of the obligation. The Company’s practice is to fund amounts for its qualified pension plans at least sufficient to meet the minimum requirements set forth in applicable employee benefit laws and local tax laws. In addition, the Company manages these plans to ensure that all present and future benefit obligations are met as they come due. During 2014, employer contributions are expected to approximate $5.0 million. As well, the Company expects to recognize amortization of actuarial gains/losses as components of net periodic benefit cost of $0.1 million. Investment decisions The Company’s overall investment strategy for pension plan assets is to achieve a blend of approximately 80 percent of investments for long-term growth and 20 percent for near-term benefit payments with a wide diversification of asset types, fund strategies and fund managers. In the U.S., the target allocations for plan assets are 40-55 percent in equity securities, 40-55 percent in corporate bonds and U.S. Treasury securities and the remainder in cash, cash equivalents or other types of investments. Equity securities primarily include investments in large-cap, mid-cap and small-cap companies principally located in the U.S. Fixed income securities include corporate bonds of companies of diversified industries and U.S. Treasuries. The plans’ weighted-average asset allocations by asset category are as follows:
| December 28, 2013 |  | December 29, 2012
Cash | 12 | % |  | 1 | %
Equity Securities | 30 | % |  | 31 | %
Fixed Income Securities | 58 | % |  | 68 | %
Total | 100 | % |  | 100 | %
The trust funds are sufficiently diversified to maintain a reasonable level of risk without imprudently sacrificing return. The investment managers select investment fund managers with demonstrated experience and expertise, and funds with demonstrated historical performance, for the implementation of the plans’ investment strategy. The investment managers will consider both actively and passively managed investment strategies and will allocate funds across the asset classes to develop an efficient investment structure. It is the responsibility of the trustee to administer the investments of the trust within reasonable costs. These costs include, but are not limited to, management and custodial fees, consulting fees, transaction costs and other administrative costs chargeable to the Trust.

Due to the divestiture of Difco in May 2011, the Company terminated the employment of the remaining employees during the fourth quarter of 2011. The terminated employees are not entitled to postretirement benefits. As a result, the Company recognized a curtailment gain of $0.6 million related to the release of the benefit obligation associated with this event. This gain appears in the line, Discontinued Operations, net in the Company’s Consolidated Statement of Operations. Assumed health care cost trend rates The health care cost trend rate assumptions for the Company provided health care benefits for retirees in Canada are reflected in the following table. The Company does not provide post-employment health care benefits for retirees in other countries.
| December 28, 2013 |  | December 29, 2012
Weighted average health care cost trend rate assumed for next year | 6.44 | % |  | 6.42 | %
Rate to which the cost trend is expected to decline (the ultimate trend rate) | 4.50 | % |  | 4.50 | %
Year that the rate reached the ultimate trend rate | 2028 |  |  | 2028 |
A one-percentage point increase in the assumed health care cost trend rate would have increased aggregate service and interest cost in 2013 by less than $0.1 million and the accumulated postretirement benefit obligation as of December 28, 2013 by $0.1 million. A one-percentage point decrease in the assumed health care cost trend rate would have decreased aggregate service and interest cost in 2013 by less than $0.1 million and the accumulated postretirement benefit obligation as of December 28, 2013 by $0.1 million. Expected Benefit Payments The following table reflects the total benefits projected to be paid from the pension plans or from the Company’s general assets, under the current actuarial assumptions used for the calculation of the projected benefit obligations. Therefore, actual payments may differ from projected benefit payments. The expected level of payments to, or on the behalf of, participants is as follows:

Defined Contribution Plans The Company sponsors several defined contribution plans through its domestic subsidiaries covering employees who meet certain service requirements. The Company makes contributions to the plans based upon a percentage of the employees’ contribution in the case of its 401(k) plans or upon a percentage of the employees’ salary or hourly wages in the case of its noncontributory money purchase plans. The cost of the plans was $2.7 million, $2.5 million and $2.5 million for fiscal 2013, 2012 and 2011, respectively.
