| ||Pool: Is a term used in several ways. From a futures trading perspective, it refers to the amount or size of unfilled orders. This inability to fill orders can occur at a limit up or limit down-market condition. For mortgages or other loans, it refers to the individual collateral underlying the security. For securitized mortgages, it can refer information such as the issuer's name, year of origination, geographic distribution, Wac, WAM and the maturity date.|
| ||Threshold for refinancing: The point when the Wac of an MBS is at a level to induce homeowners to prepay the mortgage in order to refinance to a lower-rate mortgage, generally reached when the WAC of the MBS is 2% or more above currently available mortgage rates.|
