The following table presents the components of receivables appearing in the accompanying Consolidated Balance Sheets at June 28, 2019 and September 28, 2018, as well as certain other related information (in thousands):

Total receivables and contract assets, net	$	2,779,189	$	2,513,934

Amounts billed, net consist of amounts invoiced to clients in accordance with the terms of our client contracts and are shown net of an allowance for doubtful accounts. We anticipate that substantially all of such billed amounts will be collected over the next twelve months.

Unbilled receivables and other, which represent an unconditional right to payment subject only to the passage of time, are reclassified to amounts billed when they are billed under the terms of the contract. Prior to adoption of ASC 606, receivables related to contractual milestones or achievement of performance-based targets were included in unbilled receivables. These are now included in contract assets. We anticipate that substantially all of such unbilled amounts will be billed and collected over the next twelve months.

Contract assets represent unbilled amounts where the right to payment is subject to more than merely the passage of time and includes performance-based incentives and services provided ahead of agreed contractual milestones. Contract assets are transferred to unbilled receivables when the right to consideration becomes unconditional and are transferred to amounts billed upon invoicing. The increase in contract assets was a result of normal business activity and not materially impacted by any other factors.
