intended to resolve, to the fullest extent possible, all litigation and alleged claims involving the CAE sold or manufactured by the Company's subsidiary Aearo Technologies and certain of its affiliates ("Aearo Entities") and/or

3M ("CAE Settlement"), including, but not limited to, whether the anticipated participation by plaintiffs in the CAE Settlement will be achieved, whether the number of plaintiffs that participate in the CAE Settlement will meet

current expectations or will fall below the level that would permit 3M to terminate the CAE Settlement (and whether 3M will elect to terminate the CAE Settlement if this occurs), whether there will be a significant number of future claims by plaintiffs that decline to participate in the CAE Settlement, whether the CAE Settlement is appealed or challenged, matters related to the potential issuance of the equity securities that are contemplated to be part of the CAE Settlement, the filing of additional, or the outcome of any other pending or future, litigation relating to the products that are the subject of the CAE Settlement, or changes in related laws or regulations. Changes in such assumptions or factors could produce significantly different results. A further description of these factors is located in the Reports under "Cautionary Note Concerning Factors That May Affect Future Results" and "Risk
