As of July 18, 2013 upon completion of the acquisition of Peco, the Company is now a participating employer in a trustee-managed multiemployer defined benefit pension plan for employees who participate in collective bargaining agreements. The plan generally provides retirement benefits to employees based on years of service to the Company. The multiemployer pension plan is managed by a board of trustees. Contributions are based on the hours worked and are expensed on a current basis.

The risks of participating in a multiemployer defined benefit pension plan is different from a single-employer plan because: (a) assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers, (b) if a participating employer stops contributing to the plan, the unfunded obligations of the plan may be required to be borne by the remaining participating employers, and (c) if the Company chooses to stop participating in a multiemployer plan, it may be required to pay a withdrawal liability to the plan. In connection with ongoing renegotiation of collective bargaining agreements, the Company may discuss and negotiate for the complete or partial withdrawal from its multiemployer pension plan. Depending on the number of employees withdrawn in any future period and the financial condition of the multiemployer plan at the time of withdrawal, the associated withdrawal liabilities could be material to the Company in the period of the withdrawal. The Company has no plans to withdraw from its multiemployer pension plan.

Western Conference of Teamsters Pension Plan (“WCTPP”) provides fixed retirement payments as a function of the total employer contributions payable for all service after 1986. However in the event WCTPP is underfunded, the monthly benefit amount can be reduced by the trustees of the plan. Plan information for the WCTPP, Employer Identification Number 91-6145047, is not publicly available for 2012. According to the most recently available Form 5500 for the plan year ended December 31, 2011, plan assets are $29.2 billion, the total actuarial present value of accumulated plan benefits is $35.7 billion, and contributions receivable from all employers totaled $101 million. WCTPP is over 90% funded as of the most recent financial statements.

The collective bargaining agreement of WCTPP requires contributions on the basis of hours worked. The agreement also has a minimum contribution requirement of $2.50 per compensable hour to a maximum of 184 hours per calendar year month and cumulatively to a maximum of 2080 hours per calendar year, for subsequent periods.
