Disaggregation of Revenue

We disaggregate revenue from contracts with customers by markets and geography, as we believe it best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors.

Contract Balances

We record contract assets or contract liabilities depending on the timing of revenue recognition, billings and cash collections on a contract-by-contract basis. Our contract liabilities primarily relate to deferred revenue, including advance consideration received from customers for contracts prior to the transfer of control to the customer, and therefore revenue is recognized upon delivery of products and services or as the services are performed.

The following table presents the changes in contract liabilities during fiscal year 2019 (in thousands):



	September 27, 2019		September 28, 2018		$ Change		% Change
Contract liabilities	$	10,653	$	7,757	$	2,896	37	%

As of September 27, 2019, approximately $8.5 million of our contract liabilities were recorded as other long-term liabilities on our Balance Sheet with the remainder recorded as deferred revenue. The increase in contract liabilities during the fiscal year ended September 27, 2019 was primarily from the deferral of revenue for funds received prior to when certain of our customers obtain control of the product or services, partially offset by the recognition of $7.0 million associated with a license contract.

During the fiscal year ended September 27, 2019, we recognized the following net sales as a result of changes in the contract liabilities balance (in thousands):
