Collective Bargaining and Union Agreements

Approximately 69% of the Company’s employees either are subject to various collective bargaining agreements or are members of trade unions, employee associations or workers councils predominantly outside of the United States. Approximately 12% of those employees subject to collective bargaining agreements, or 9% of the Company’s total employees, are covered by agreements that are set to expire during 2015.

Legal Proceedings

The Company and its subsidiaries are involved in various legal matters, which have arisen in the ordinary course of business as a result of various labor claims, taxing authority reviews and other legal matters. As of December 31, 2014, the Company had accrued an immaterial amount in its financial statements for these matters for which (1) management believed the possibility of loss was either probable or possible, and (2) was able to estimate the damages. These estimates have been developed in consultation with counsel and are based upon an analysis of potential results, assuming a combination of litigation and settlement strategies. It is possible, however, that future results of operations for any particular period could be materially affected by changes in the Company’s assumptions or the effectiveness of our strategies related to these proceedings.

Environmental Matters

The Company’s operations and facilities are subject to a number of national, state and local laws and regulations protecting the environment and human health in the United States and foreign countries that govern, among other things, the handling, storage and disposal of hazardous materials, discharges of pollutants into the air and water and workplace safety. Because of the Company’s operations, the history of industrial uses at some of these facilities, the operations of predecessor owners or operators of some of the businesses, and the use and release of hazardous substances at these sites, the liability provisions of environmental laws may affect the Company. The Company is not aware of any material unasserted claims.

The Company believes that any additional liability in excess of amounts provided which may result from the resolution of such matters will not have a material adverse effect on the financial condition, liquidity or cash flow of the Company.
