Deferred Revenue [Abstract]

Deferred Revenue

Deferred Revenue

Deferred maintenance revenue consists of prepaid fees received for post-contract customer support for our products, including telephone support and the right to receive unspecified upgrades/updates on a when-and-if-available basis. Unearned revenue includes fees for up-front setup of the service environment; fees charged for on-demand service; certain software arrangements for which we do not have fair value of post-contract customer support, resulting in ratable revenue recognition for the entire arrangement on a straight-line basis; and fees in excess of estimated earnings on percentage-of-completion service contracts.
