| Amendment Description | On November 18, 2022, Honeywell International Inc. (“Honeywell”) filed a Current Report on Form 8-K (the “Original Form 8-K”) with the Securities and Exchange Commission disclosing, among other things, that Honeywell had entered into a definitive agreement (the “Buyout Agreement”) with the North American Refractories Asbestos Personal Injury Settlement Trust (the “Trust”), providing for the elimination of Honeywell’s funding obligations to the Trust. In the Original Form 8-K, Honeywell stated that it intended to file a copy of the Buyout Agreement as an exhibit to an amendment to the Original Form 8-K. Honeywell is now filing this Amendment No. 1 to the Original Form 8-K (“Amendment No. 1”) solely to file the Buyout Agreement as an exhibit. This Amendment No. 1 does not change any previously reported information or any disclosure contained in the Original Form 8-K. |
