New York, NY – MIAC Analytics™ relaunches Mortgage Industry Medians (MIMs™), a dealer consensus prepayment projection survey, a successor to SIFMA’s Mortgage Prepayment Projection Tables.

Mortgage Industry Advisory Corporation (MIAC), provider of financial analytics solutions, relaunches MIMs™, a Wall St. dealer consensus long-term prepayment projection survey, based upon a survey of leading industry market makers for MBS securities. MIAC has assumed responsibility for this survey that has been ongoing since 1986 and was most recently handled by SIFMA[1].  MIAC has recently updated the dealer consensus survey to include 2013, 2014, 2015 and 2016 issue year cohorts for more market relevancy.  MIAC has also streamlined the survey from the original 192 cohorts to 127 cohorts encompassing a full spectrum of the most widely traded MBS securities today, which now include Jumbo and Hybrid cohorts.  Moreover, the cohorts include WAC, WAM, WALA, FICO, mtm-LTV and submission-time guidelines, to ensure full transparency and consistency to better serve the survey’s subscribers.

MIAC’s MIMs dealer consensus prepayment data also links directly into MIAC’s software applications, most notably, MIAC’s portfolio valuation tools, WinOAS™ and MIAC|DS™. Both tools are widely used to perform MSR, whole loan and MBS valuations. MIMs™ users can also elect to subscribe to Dynamic MIMs™, which enables users to forecast a dealer consensus prepayment projection for given changes in mortgage rates as mortgage rates change.

“We are excited to announce the relaunch of the MIMs™ dealer consensus survey and Dynamic MIMs™ as the newest addition to the MIAC Analytics™ suite of data products. MIAC has leveraged its many years of experience performing asset valuation services and to build a better survey, with the ultimate goal of improving MBS Analytics for all parties involved. We will continue to follow industry trends and make meaningful improvements to the survey, as we understand the importance of projecting prepayments and the vital difference a well-maintained dealer consensus survey can make in MBS and MSR Analytics.” – Paul Van Valkenburg, Principal, Mortgage Industry Advisory Corporation
