The following table disaggregates the company’s net sales based on the timing of transfer of control:

	Year Ended December 31, 2019
($ in millions)	Point in Time		Over Time		Total
Total net sales	$	2,220	$	9,254	$	11,474
	Year Ended December 31, 2018
($ in millions)	Point in Time		Over Time		Total
Total net sales	$	2,634	$	9,001	$	11,635

The company did not have any contract assets at either December 31, 2019, or December 31, 2018. The opening and closing balances of the company’s current and noncurrent contract liabilities are as follows:

	Contract		Contract
	Liabilities		Liabilities
($ in millions)	(Current)		(Noncurrent)
Balance at December 31, 2017	$	45	$	—
Increase		—		8
Balance at December 31, 2018	$	45	$	8
Increase		42		1
Balance at December 31, 2019	$	87	$	9

During the year ended December 31, 2019, contract liabilities increased by $43 million, which is net of cash received of $254 million and amounts recognized as sales of $211 million, all of which related to current contract liabilities. The amount of sales recognized during the year ended December 31, 2019, that were included in the company’s opening contract liabilities balance was $45 million, all of which related to current contract liabilities. The difference between the opening and closing balances of the company’s contract liabilities primarily results from timing differences between the company’s performance and the customer’s payment. Current contract liabilities are classified within other current liabilities on the consolidated balance sheet and noncurrent contract liabilities are classified within other liabilities.

The company also recognized sales of $15 million and $18 million during the years ended December 31, 2019 and 2018, respectively, from performance obligations satisfied (or partially satisfied) in prior periods. These sales amounts are the result of changes in the transaction price of the company’s contracts with customers.

Transaction Price Allocated to Remaining Performance Obligations

The table below discloses: (1) the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied (or partially unsatisfied) as of the end of the reporting period, for those contracts with an original duration of at least one year, and (2) when the company expects to record sales on these multi-year contracts.

($ in millions)	Next Twelve Months		Thereafter		Total
Sales expected to be recognized on multi-year contracts in place as of December 31, 2019	$	1,409	$	1,067	$	2,476

The contracts with an original duration of less than one year, which are excluded from the table above based on the company’s election of the practical expedient, are primarily related to contracts where control will be fully transferred to the customers in less than one year. The nature of the remaining performance obligations within these contracts, as well as the nature of the variability and how it will be resolved, are described in Note 1.
