Auto finance credit performance continued to improve across securitized prime and non-prime auto loan collateral pools during the April collection period, according to Kroll Bond Rating Agency (KBRA).

Both of Kroll’s indices benefited from the effects of tax filing season, as many late filers received their refunds in late April. However, with the effects of the tax season now in the rear-view mirror, Kroll expects credit performance to slowly deteriorate over the coming months.

The percentage of borrowers who went from 60-plus days delinquent to current in April was 22.8 percent for prime consumers and 16.8 percent for subprime consumers. This is down from 24.8 percent and 21.5 percent respectively during the previous month.
