Revenue. Revenue includes sales of pharmaceutical products, amortization of licensing fees, and, if any, milestone payments for R&amp;D achievements. Product Sales and Services Revenue is generally realized or realizable and earned when persuasive evidence of an arrangement exists, delivery has occurred or services have been rendered, the sellers price to the buyer is fixed or determinable, and collectability is reasonably assured.
