REMICs

Real Estate Mortgage Investment Conduits (REMICs) feature customized structuring of mortgage pass-through securities to redistribute cash flows.

Freddie Mac offers a variety of REMIC products, working closely with dealers and investors to tailor the security cash flows to meet a variety of investment needs. Freddie Mac's REMIC Dealer Group dealers serve as quality underwriters and liquidity providers of REMIC products.

What Is a REMIC?

REMICs, created by the Tax Reform Act of 1986, are multiclass, mortgage-backed securities in which cashflows from the underlying mortgage assets are allocated to individual bond slices, called tranches, with different maturities, coupons and payment priorities thereby allowing greater flexibility in structuring.

REMICs are sometimes referred to as CMOs, or Collateralized Mortgage Obligations. Freddie Mac began issuing REMICs in March 1988 and issued the first REMIC backed by Gold PCs in October 1990.
