The offer was made in order to comply with certain requirements in AWI's governing documents, following Armor TPG's acquisition of seven million shares of AWI's common stock and an economic interest in approximately 1 million additional shares of AWI's common stock from the Armstrong World Industries, Inc. Asbestos Personal Injury Settlement Trust on August 28, 2009. In the tender offer documents, Armor TPG cautioned shareholders considering tendering shares that they might be able to obtain a higher price by selling shares in the open market rather than pursuant to the offer.

The depositary for the tender offer has advised Armor TPG that shareholders of AWI have tendered and not withdrawn a total of 1,149 shares of AWI common stock, which shares have been accepted for payment by Armor TPG. Following the tender offer, Armor TPG continues to directly own approximately 12.2% percent of the 57,347,726 shares of AWI outstanding as of September 1, 2009.
