The complaint seeks among other items, damages in an unspecified amount, replacement costs, injunctive relief, and attorneys’ fees and costs. The Company is unable to estimate a range of reasonably possible loss for the above matter in which damages have not been specified because: (i) the proceedings are in the early stages; (ii) there is uncertainty as to the likelihood of a class being certified or the ultimate size of the class; (iii) there are significant factual issues to be resolved; and (iv) there are novel legal issues presented.

Product Liability The Company is subject to a variety of potential liabilities in connection with product liability cases. The Company maintains product liability and other insurance coverage, which the Company believes to be generally in accordance with industry practices. For product liability cases in the U.S., management establishes its product liability accrual by utilizing third-party actuarial valuations which incorporate historical trend factors and the Company’s specific claims experience derived from loss reports provided by third-party administrators.

Environmental liabilities are recorded based on the most probable cost, if known, or on the estimated minimum cost of remediation. Accruals are not discounted to their present value, unless the amount and timing of expenditures are fixed and reliably determinable. The Company accrues estimated environmental liabilities based on assumptions, which are subject to a number of factors and uncertainties.

The Company recognizes changes in estimates as new remediation requirements are defined or as new information becomes available. Asbestos Litigation The Company is defending approximately 42 lawsuits in different jurisdictions, alleging injury or death as a result of exposure to asbestos. The complaints in these cases typically name a large number of defendants and do not identify any particular Company products as a source of asbestos exposure. To date, the Company has obtained a dismissal in every case before it has reached trial because discovery has failed to yield evidence of substantial exposure to any Company products.
