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/enhancements on a when-and-if-available basis. Unearned revenue includes upfront fees for setup and implementation activities related to hosted offerings; 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.

The increase in unearned revenue is primarily driven by growth in our handset and automotive connected services in our Mobile segment, for which a portion of the fees are collected in advance while the revenue recognition period extends over the service period.
