Employee Benefit Plans

Multi-Employer Benefit Plans

Certain of the Company's subsidiaries, including certain of the Acquired Subsidiaries, participate in multi-employer benefit pension plans under the terms of collective-bargaining agreements. The Company's contributions were $0.9 million and $1.8 million during the three and six months endedJanuary 25, 2014, respectively, and $0.8 million and $1.8 million during the three and six months endedJanuary 26, 2013, respectively. The risks of participating in a multi-employer defined benefit pension plan are different from single-employer plans in the following aspects: (a) assets contributed to the multi-employer plan by one employer may be used to provide benefits to employees of any other participating employers; (b) if a participating employer stops contributing to the plan, the unfunded obligations of the plan may become obligations of the remaining participating employers; and (c) if the Company chooses to stop participating in the multi-employer plan, the Company may be required to pay the plan an amount based on the underfunded status of the plan, referred to as a withdrawal liability. The Company has not incurred withdrawal liabilities related to the plans as of January 25, 2014 or July 27, 2013.
