LDL Lydall Inc

As previously disclosed on August 30, 2017, Lydall, Inc. (“Lydall” or the “Company”) announced its intention to combine the Thermal/Acoustical Metals and Thermal/Acoustical Fibers segments into a single operating segment named Thermal Acoustical Solutions. Combining these automotive businesses into one segment is expected to allow for better customer alignment, leverage operating disciplines and realize efficiencies across the global automotive operations. Through December 31,2017, these two operating segments continued to be managed separately as the Company defined the future global structure and strategies of the combined businesses. Effective January 1, 2018, the Company commenced reporting of the two businesses as a single consolidated operating segment.

The Company did not operate under this structure for any of these prior periods and will begin to report comparative results under the new structure with the filing of its Quarterly Report on Form 10-Q for the quarter ending March 31, 2018. On March 21, 2018, the Company made available on its website unaudited historical quarterly and full-year financial data for 2017 and 2016 that has been recast to reflect its new segment reporting structure.
