Refunds

Revenue allocated to an element is not considered collectible and is subject to forfeiture, refund or other concessions. Therefore management must intend not to accept returns or grant concessions. If a vendor has a historical pattern of making refunds or granting concessions on delivered elements not required under the original provisions of its arrangements due to non-delivery of the elements, no other lvidence is persuasive enough to reach a conclusion that revenue in current arrangements with similar elements is not subject to forteiture.
