Deferred Revenue And Financing Receivables [Abstract]
Deferred Revenue and Financing Receivables	Deferred Revenue and Financing Receivables Deferred Revenue Deferred revenue primarily relates to software 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 prepaid expenses and other current assets. Billed but uncollected support and subscription-related amounts included in other current assets at December 31, 2016 and September 30, 2016 were $112.4 million and $126.3 million, respectively. Financing Receivables We periodically provide extended payment terms to credit-worthy customers for software purchases with payment terms up to 24 months. The determination of 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 and customers generally. This determination is based on an internal credit assessment. As of December 31, 2016 and September 30, 2016, amounts due from customers for contracts with original payment terms greater than twelve months (financing receivables) totaled $6.0 million and $7.1 million, respectively, all of which was included in accounts receivable in the Consolidated Balance Sheets. We evaluate the need for an allowance for doubtful accounts for estimated losses resulting from the inability of these customers to make required payments. As of December 31, 2016 and September 30, 2016, 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, 2016 or January 2, 2016. We write off uncollectible trade and financing receivables when we have exhausted all collection avenues. 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.

Deferred Revenue and Financing Receivables

Deferred Revenue

Deferred revenue primarily relates to software 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 prepaid expenses and other current assets. Billed but uncollected support and subscription-related amounts included in other current assets at December 31, 2016 and September 30, 2016 were $112.4 million and $126.3 million, respectively.

Financing Receivables

We periodically provide extended payment terms to credit-worthy customers for software purchases with payment terms up to 24 months. The determination of 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 and customers generally.
