Deferred Revenue And Financing Receivables [Abstract]
Deferred Revenue And Financing Receivables	Deferred Revenue and Financing Receivables Deferred Revenue Deferred revenue primarily relates to software maintenance agreements billed to customers for which the services have not yet been provided. The liability associated with performing these services is included in deferred revenue and, if not yet paid, the related customer receivable is included in other current assets. Billed but uncollected maintenance-related amounts included in other current assets at December 31, 2011 and September 30, 2011 were $84.4 million and $93.0 million, respectively. Financing Receivables We periodically provide extended payment terms for software purchases to credit-worthy customers with payment terms up to 24 months. The determination on whether to offer such payment terms is based on the size, nature and credit-worthiness of the customer, and the history of collecting amounts due, without concession, from the customer. As of December 31, 2011 and September 30, 2011, amounts due from customers for contracts with extended payment terms (financing receivables) totaled $75.6 million and $72.3 million, respectively. Accounts receivable in the accompanying consolidated balance sheets include current receivables from such contracts totaling $61.0 million and $55.2 million at December 31, 2011 and September 30, 2011, respectively, and other assets in the accompanying consolidated balance sheets include long-term receivables from such contracts totaling $14.6 million and $17.1 million at December 31, 2011 and September 30, 2011, respectively. We evaluate estimated credit losses on financing receivables based on whether the customers are making payments as they become due, customer credit-worthiness and existing economic conditions. We write off uncollectible trade and financing receivables when we have exhausted all collection avenues. As of December 31, 2011 and September 30, 2011, we concluded that all financing receivables were collectible and no reserve for credit losses was recorded. We did not provide a reserve for credit losses or write off any uncollectible financing receivables in the three months ended December 31, 2011 and fiscal year 2011. We periodically transfer future payments under certain of these contracts to third-party financial institutions on a non-recourse basis. We record such transfers as sales of the related accounts receivable when we surrender control of such receivables. We sold $6.3 million of financing receivables to third-party financial institutions in the three months ended December 31, 2011. We sold no financing receivables to third-party financial institutions in the three months ended January 1, 2011.

Deferred Revenue and Financing Receivables

Deferred Revenue

Deferred revenue primarily relates to software maintenance agreements billed to customers for which the services have not yet been provided. The liability associated with performing these services is included in deferred revenue and, if not yet paid, the related customer receivable is included in other current assets. Billed but uncollected maintenance-related amounts included in other current assets at December 31, 2011 and September 30, 2011 were $84.4 million and $93.0 million, respectively.

Financing Receivables
