Enhancement: subordinate notes, overcollateralization and reserve beneath the class, as a share of the pool net of any yield supplement (the adjusted pool, as the issuers and rating agencies measure it); the Class A notes share losses pari passu, so each carries the same figure. Spread: basis points over the benchmark named beside it, from the pricing term sheet — the interpolated curve for fixed-rate classes, 30-day average SOFR for floaters; the two are not comparable. A class marked retained was kept by the depositor, as the prospectus states.

Enhancement: subordinate notes, overcollateralization and the reserve account as a share of the cutoff-date pool — the losses the pool can absorb before the AAA term notes are touched. AAA spread: the pricing spread over the interpolated curve for the fixed-rate AAA class whose weighted-average life is nearest two years, with that class and its WAL shown; floating-rate classes are never used. Source: 424B5 = final prospectus, FWP = pricing term sheet, calc = derived from the above. Deltas are against the peer median; green means more protection, or a cheaper price for it, for the noteholder.

OC shown net of any yield-supplement overcollateralization (YSOC); YSOC is a yield mechanism for subvented low-APR pools and is reported separately. OC target is a % of the pool balance — current (amortizing) for greater-of/sum-of structures, original (cut-off) for flat structures; OC floor is a % of the original pool balance.

Historical Performance Context

Anchor expectations in empirical base rates from the sponsor's prior series and FICO-tier peer set.

Left: per-series cumulative NET loss at matched seasoning 10-D (10-D servicer distribution reports). IQR band uses a fixed cohort of all peer series with ≥18 months of data (88 series across 3 issuers). Right: portfolio-level 60+ DQ rate aggregated across all active deals per issuer (calendar time, last 3 years), from ABS-EE loan-level data ABS-EE.
