Credit default swaps reference not a corporate bond, but rather an asset-backed security such as RMBS and CMBS, and are subject to a separate ISDA template. The "Pay-AsYou-Go" (PAUG) template for home equity loan (HEL) ABS was issued in 2005 by the International Swaps and Derivatives Association (ISDA) and is the benchmark ABCDS format. According to Nomura on March 7, 2005, "A HEL ABS typically has a long maturity, so the maturity of the CDS contract tends to match that of the reference bond. A PAUG CDS referencing HEL ABS does not terminate even after multiple trigger events (called 'floating amount events'). A floating amount event may be reversed in a subsequent period, in which case previous floating payments to the protection buyer must be reimbursed to the protection seller. The notional amount of a ABCDS is adjusted as any of the reference home equity loans (1) amortizes, (2) prepays, (3) is written down, (4) defaults, or as previous floating amount events are reversed."
