We recognized increases to revenue of $2 million, $4 million, and $9 million in 2019, 2018, and 2017, respectively, for variable consideration related to performance obligations settled in previous periods.

We record contract assets for items for which we have satisfied our performance obligation but our receipt of payment is contingent upon delivery or other circumstances other than the passage of time. Our contract assets are recorded in prepaid expenses and other in our consolidated balance sheets. Our contract assets generally become unconditional and are reclassified to receivables in the quarter subsequent to each balance sheet date. Our contract asset balance was $2 million at both December 31, 2019 and 2018.

We record contract liabilities primarily for deferred revenue. Our contract liabilities are recorded in accrued liabilities in our consolidated balance sheets. Our contract liabilities are generally recognized to net sales in the immediately subsequent reporting period. Our contract liability balance was $40 million and $39 million at December 31, 2019 and 2018, respectively.
