Deferred Revenue	Sep. 30, 2013
Revenue Recognition [Abstract]
Deferred Revenue	Deferred Revenue — Deferred revenue on a consolidated basis at September 30, 2013 was $28.0 million for the current portion and $0.4 million for the non-current portion. Deferred revenue at September 30, 2013 primarily consisted of unearned maintenance, license and professional services revenue and customer deposits for installation services related to our software operations. Unearned maintenance revenue represented a contractual liability to provide maintenance support over a defined period of time for which payment has generally been received. Unearned license and professional services revenue represented a contractual liability to provide professional services more substantive than post contract support. At September 30, 2013, we had received $5.8 million in customer deposits for future installation services. We will recognize revenue when the service or software is delivered and all other revenue recognition criteria have been satisfied.
