Contingencies During February 2014, a cylinder was sold to a long-term customer and ruptured at one of their gas facilities. As a result of this rupture, three people were noted to have injuries, such as loss of hearing. There was no major damage to assets of the customer. A claim has been launched by the three people who were injured in the incident. We have reviewed our quality control checks from around the time that the cylinder was produced, and no instances of failures have been noted. It has also been noted by the investigator that the customer has poor quality and safety checks. In November 2021, during the final hearing, the Court found the representative of Luxfer Gas Cylinders Limited, not guilty and thus the Company was found not liable. The Civil case is still ongoing but as a result of the above, we do not believe that we are liable for the incident, and therefore, do not currently expect this case to have a material impact on the Company's financial position or results of operations. In November 2018, an alleged explosion occurred at a third-party waste disposal and treatment site in Boise, Idaho, reportedly causing property damage, personal injury, and one fatality. We had contracted with a service company for removal and disposal of certain waste resulting from the magnesium powder manufacturing operations at the Reade facility in Manchester, New Jersey. We believe this service company, in turn, apparently contracted with the third-party disposal company, at whose facility the explosion occurred, for treatment and disposal of the waste. In November 2020, we were named as a defendant in three lawsuits in relation to the incident – one by the third-party disposal company, one by the estate of the decedent, and one by an injured employee of the third-party disposal company. At present, we have received insufficient information on the cause of the explosion. We do not believe that we are liable for the incident, have asserted such, and, therefore, do not currently expect this matter to have a material impact on the Company’s financial position or results of operations.
