Revenue from Contracts with Customers
Revenue by Market
The table below presents disaggregated net revenues by market (in thousands):
(1) Due to the adoption of ASC 606 using the modified retrospective method, prior period amounts have not been adjusted to reflect the change to recognize certain distributor sales upon sale to the distributor, or the sell-in method, from recognition upon the Company's sale to the distributors' end customers, or the sell-through method, which required the deferral of revenue and profit on such distributor sales.
As of December 31, 2018, customer contract liabilities consist of estimates of obligations to deliver rebates to customers in the form of units of products and were approximately $0.1 million. Revenue recognized in the year ended December 31, 2018 that was included in the contract liability balance as of January 1, 2018 was immaterial.
There were no material changes in the contract liabilities balance during the year ended December 31, 2018.
Obligations to Customers for Price Adjustments and Returns and Assets for Right-of-Returns
As of December 31, 2018, obligations to customers consisting of estimates of price protection rights offered to the Company's end customers totaled $16.5 million and are included in accrued price protection liability in the consolidated balance sheets. For activity in this account, including amounts included in net revenue, refer to Note 7. Other obligations to customers representing estimates of price adjustments to be claimed by distributors upon sell-through of their inventory to their end customer and estimates of stock rotation returns to be claimed by distributors on products sold as of December 31, 2018 were $7.6 million and $1.5 million, respectively, and are included in accrued expenses and other current liabilities in the consolidated balance sheets (Note 7). The increase in revenue from net changes in transaction prices for amounts included in obligations to customers for price adjustments as of January 1, 2018 was not material. As of December 31, 2018, right of return assets under customer contracts representing the estimates of product inventory the Company expects to receive from customers in stock rotation returns were approximately $0.3 million. Right of return assets are included in inventory in the consolidated balance sheets (Note 7).
As of December 31, 2018, there were no impairment losses recorded on customer accounts receivable.
