Revenue by Market The table below presents disaggregated net revenues by market (in thousands):
(1) Due to the adoption of ASC 606 on January 1, 2018 using the modified retrospective method, amounts prior to 2018 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 sellthrough method, which required the deferral of revenue and profit on such distributor sales.
Revenues from sales to the Company’s distributors accounted for 52%, 42% and 34% of net revenue for the years ended December 31, 2019, 2018 and 2017, respectively.
Question:
After using the modified retrospective method, amounts prior to which year have not been adjusted?
