Retail Finance Receivables We use proprietary scoring systems in the underwriting process that measure the credit quality of retail finance receivables using several factors, such as credit bureau information, consumer credit risk scores (e.g. FICO score or its equivalent) and contract characteristics. We also consider other factors such as employment history, financial stability and capacity to pay. Subsequent to origination we review the credit quality of retail finance receivables based on customer payment activity. At December 31, 2019 and 2018 24% and 25% of retail finance receivables were from consumers with sub-prime credit scores, which are defined as a FICO score or its equivalent of less than 620 at the time of loan origination.

We purchase retail finance contracts from automobile dealers without recourse, and accordingly, the dealer has no liability to GM Financial if the consumer defaults on the contract. Finance receivables are collateralized by vehicle titles and GM Financial has the right to repossess the vehicle in the event the consumer defaults on the payment terms of the contract.

An account is considered delinquent if a substantial portion of a scheduled payment has not been received by the date the payment was contractually due. The accrual of finance charge income had been suspended on delinquent retail finance receivables with contractual amounts due of $875 million and $888 million at December 31, 2019 and 2018. The following table summarizes the contractual amount of delinquent retail finance receivables, which is not significantly different than the recorded investment of the retail finance receivables:



	December 31, 2019				December 31, 2018
	Amount		Percent of Contractual Amount Due		Amount		Percent of Contractual Amount Due
31-to-60 days delinquent	$	1,354	3.2	%	$	1,349	3.3	%
Greater-than-60 days delinquent	542		1.3	%	547		1.4	%
Total finance receivables more than 30 days delinquent	1,896		4.5	%	1,896		4.7	%
In repossession	44		0.1	%	44		0.1	%
Total finance receivables more than 30 days delinquent or in repossession	$	1,940	4.6	%	$	1,940	4.8	%

Commercial Finance Receivables Our commercial finance receivables consist of dealer financings, primarily for inventory purchases. Proprietary models are used to assign a risk rating to each dealer. We perform periodic credit reviews of each dealership and adjust the dealership's risk rating, if necessary. Dealers in Group VI are subject to additional restrictions on funding, including suspension of lines of credit and liquidation of assets. The commercial finance receivables on nonaccrual status were insignificant at December 31, 2019 and 2018. The following table summarizes the credit risk profile by dealer risk rating of the commercial finance receivables:



		December 31, 2019		December 31, 2018
Group I	– Dealers with superior financial metrics	$	1,942	$	2,192
Group II	– Dealers with strong financial metrics	4,552		4,399
Group III	– Dealers with fair financial metrics	3,711		4,064
Group IV	– Dealers with weak financial metrics	968		1,116
Group V	– Dealers warranting special mention due to elevated risks	370		422
Group VI	– Dealers with loans classified as substandard, doubtful or impaired	128		83
