Separation and Distribution Agreement

On March 11, 2016, in connection with the proposed separation of the Resilient Flooring and Wood Flooring segments of Armstrong World Industries, Inc. (“AWI”) from AWI’s Building Products (Ceilings) segment by means of a spin-off of a newly formed company named Armstrong Flooring, Inc. (“AFI”), AFI entered into a Separation and Distribution Agreement (the “Separation and Distribution Agreement”) with AWI that sets forth, among other things, certain agreements between AWI and AFI regarding the principal transactions necessary to effect the separation and the pro rata distribution to AWI’s shareholders of 100% of AFI’s outstanding common stock (the “Separation and Distribution”). The Separation and Distribution Agreement also sets forth other agreements that govern certain aspects of AFI’s ongoing relationship with AWI after the completion of the Separation and Distribution. A description of the terms and conditions of the Separation and Distribution Agreement that are material to AFI can be found in AFI’s information statement, which was attached as Exhibit 99.1 to Amendment No. 4 to AFI’s Registration Statement on Form 10 filed with the Securities and Exchange Commission on March 11, 2016, under the section entitled “Certain Relationships and Related Person Transactions-Separation and Distribution Agreement,” which is incorporated by reference into this Item 1.01.
