Asset-Backed Securities (ABS) + Mortgage-Backed Securities (MBS) 
Asset-backed securities (ABS) result from the securitization of receivables, which the creditor (originator) sells in order to create liquidity. The creditor pools the receivables, and sells them to a trust set up for this purpose. The trust refinances the receivables by issuing tradable securities, which are backed by the receivables.
Mortgage-backed securities (MBS) are created in the same way, but the securitized assets are mortgage loans only. All other types of assets can be securitized in asset-backed securities.
