Winnie are you refer to this initiatives? The OUS Initiatives was implemented by Freddie Mac on April 13 2011
Freddie Mac Multifamily Data Delivery users will begin using the new Origination and Underwriting System (OUS) to perform current Data Delivery functions. The initial phase of OUS launching in 2011 will primarily provide a new set of capabilities for the Freddie Mac production and underwriting staff that is designed to help improve the efficiency of the underwriting process. Weâ€™ve changed our system name from MultiSuiteÂ® for Data Delivery to the Origination and Underwriting System (OUS) to reflect this expanded functionality.
Implementing MARS in two stages with the first implementation for cash mortgages, and the second implementation for bonds and Tax Exempt Bond Securitizations (TEBS). Once the first phase implements, Seller/Servicers who have both cash and bond mortgages will need to use two different reporting systems. MARS for cash mortgages and the current system, MSIR for bonds, but just until the second implementation phase of MARS is complete.
