medium · Asset-Backed Securities waterfalls

In a subprime auto ABS transaction (e.g., Autumn Finance 2026-A), the 'Overcollateralization (OC) Build' phase is active for the first 6 months.

If cumulative net losses (CNL) reach 1.5% in month 5, exceeding the trigger threshold of 1.2%, what is the impact on the waterfall?

  1. The OC target is increased, and all excess spread is diverted to pay down senior bonds until the new target is met.
  2. The transaction immediately enters 'Rapid Amortization,' and the loan servicer is terminated without any cure period.
  3. The reserve account is fully released to subordinate bondholders despite the ongoing trigger breach event here.
  4. The residual holder receives a 'catch-up' payment covering every previously missed distribution from prior collection periods.
