The following table disaggregates revenues by type within each of our business segments:

Gaming
Gaming operations(1)	$	155	$	113
Gaming machine sales	103		55

(1) Gaming operations revenue for the three months ended March 31, 2021 benefited from $6 million U.K. fixed odds betting terminals (“FOBT”) recovery received from certain U.K. customers for value-added tax charged on FOBTs (“FOBT recovery”) related to a 2020 U.K. court ruling associated with overcharging of value-added tax for gaming operators that consequently reduced our net gaming revenues in those affected prior periods related to these customers and arrangements.
(2) Other primarily represents revenue generated from providing advertising platforms with access to our game software platform, which facilitates the placement of advertising inventory, which was not material in the periods presented.

The amount of rental income revenue that is outside the scope of ASC 606 was $113 million and $63 million for the three months ended March 31, 2022, and 2021, respectively.

Contract Liabilities and Other Disclosures

The following table summarizes the activity in our contract liabilities for the reporting period:

	Three Months Ended March 31, 2022
Contract liability balance, beginning of period(1)	$	37
Liabilities recognized during the period	5
Amounts recognized in revenue from beginning balance	(5)
Contract liability balance, end of period(1)	$	37
(1) Contract liabilities are included within Accrued liabilities and Other long-term liabilities in our consolidated balance sheets.

The timing of revenue recognition, billings and cash collections results in billed receivables, unbilled receivables (contract assets), and customer advances and deposits (contract liabilities) on our consolidated balance sheets. Other than contracts with customers with financing arrangements exceeding 12 months, revenue recognition is generally proximal to conversion to cash. The following table summarizes our balances in these accounts for the periods indicated (other than contract liabilities disclosed above):

	Receivables		Contract Assets(1)
Beginning of period balance	$	440	$	19
End of period balance, March 31, 2022	448		25
(1) Contract assets are included primarily within Prepaid expenses, deposits and other current assets in our consolidated balance sheets.

As of March 31, 2022, we did not have material unsatisfied performance obligations for contracts expected to be long-term or contracts for which we recognize revenue at an amount other than for which we have the right to invoice for goods or services delivered or performed.
