Deferred Revenue Disclosure [Abstract]

Generally, revenue is recognized upon fulfillment of acceptance criteria at the Company's factory and title transfer which frequently occurs at the time of delivery to a common carrier. Revenue is deferred whenever title transfer is pending and/or acceptance criteria have not yet been fulfilled. Deferred revenue occurrences include sales to Japanese customers, shipments of substantially new products and shipments with custom specifications and acceptance criteria. In sales involving multiple element arrangements, the relative selling price of any undelivered elements, including installation services, is deferred until the elements are delivered and acceptance criteria are met. Revenue related to maintenance and service contracts is deferred and recognized ratably over the duration of the contracts.

The following is a reconciliation of the changes in deferred revenue:
