As discussed in Note 4 above, deferred revenue relates to our divestiture of the Reddick product line and an associated transition services agreement that we entered into contemporaneously with the divestiture, under which we agreed to manufacture and sell product to the buyer at prices at or below our cost. We allocated a portion of the consideration received from the divestiture to this transition services agreement to reflect it at fair value and recorded it as deferred revenue. As the products are sold to the buyer, which we expect will occur over approximately the next nine to twelve months, we amortize a portion of the deferred revenue to adjust the gross margin on the sale to fair value on a specific identification basis. The following table summarizes the changes in the deferred revenue balance during the nine months ended September 30, 2018:
