During the three and twelve months ended December 31, 2018, we recognized a decrease of revenues of $46 and an increase of $22, respectively, that were included in contract liabilities at the beginning of the period.

The increase in contract liabilities as of December 31, 2018 is primarily due to net increases in estimated future discounts and price concessions, offset by net settlements of products sold with rights of return.
