The Company participates in 20 regional multi-employer pension plans, principally related to building trades; none of the plans are considered significant to the Company.

Effective January 1, 2010, the Company froze all future benefit accruals under substantially all of the Company’s domestic qualified and non-qualified defined benefit pension plans. Future benefit accruals related to the Company’s foreign non-qualified plans were frozen several years ago.
