Latest Social Index Daily Issuance File (updated by approximately 11:30 am to include previous day's issuance)

Social Index Historical Issuance File  (includes issuances from January 2010 to November 2022)

Social Index Disclosure File Format

The Social Index disclosures include two measures: Social Criteria Share (SCS) and Social Density Score (SDS). These new disclosures are intended to give the market more information about the underlying social characteristics of the pools at issuance while protecting the privacy of the borrowers.

As shown in the diagram below, these measures are supported by eight specific social criteria which are distributed across three dimensions. The share of loans within the pool meeting any one of the eight social criteria is reflected in the Social Criteria Share (SCS).

Social Criteria Share

The eight social criteria are classified into three dimensions: Income, Borrower and Property. If a loan meets any one of the social criteria mapped to the social dimension, the loan receives a value of 1 for that dimension. The loan-level score is the count of the social dimensions it satisfies.

The Social Density Score (SDS) reflects the simple average of the loan-level scores within the pool.

Social Criteria Dimensions

Important notes

  • Loans are evaluated at the time of acquisition.
  • Second Homes are excluded from eligibility for all social criteria.
  • The SCS and SDS are disclosed only for pools with >= 10 loans (must be non-second homes) at the time of pool issuance.
  • The SCS and SDS are reflected as of pool issuance and are not updated as pools season.
  • The SDS is limited to a maximum of 2.5 out of 3.0.

To support market understanding and adoption, Freddie Mac published a one-time historical file which includes the at-issuance SCS and SDS for all active and inactive/paid off pools issued since January 2010.

As the Enterprises work toward implementing the Social Index on the aligned disclosure files, Freddie Mac is posting the Social Index values for all newly-issued pools on its website daily.

We have not labeled or otherwise designated any of our UMBS, MBS or PCs as “Social MBS.” The Social Index is an emerging methodology that may evolve over time. There is no clear definition in the U.S. (legal, regulatory or otherwise) or market consensus as to what constitutes, or what precise attributes are required for a particular asset to constitute, a “social,” “sustainable,” “ESG” or similarly-designated asset, nor can any assurance be given that a clear definition or market consensus will develop over time. The Social Index has not been designed to satisfy any social, sustainable, affordable or other criteria of any framework or principles. Accordingly, we cannot assure you that the securities will be suitable for any particular “social,” “sustainable,” “ESG” or other similarly-designated investment objectives, mandates or strategies.

We cannot predict the level of market interest, if any, for securities with any particular SCS or SDS score or how the Social Index methodology may evolve over time. A secondary market for securities with particular SCS or SDS scores may not develop. Even if a market develops, it may not continue. As a result, you may not be able to sell securities with relatively high SCS or SDS scores at prices that will allow you to realize a higher return based on such relatively high SCS or SDS scores.

The assignment of a SCS and SDS is not a recommendation to buy, sell or hold a security and is only current as of the date of the issuance of such security. The SCS and SDS for our securities are based on information furnished to us by the sellers of the underlying mortgages. We have not verified such information, make no representations or warranties concerning the accuracy of the SCS and SDS for our securities, and disclaim all liability associated with or arising from any inaccuracies in the SCS and SDS. The SCS or SDS for a security could be incorrect due to, among other items, errors in the information provided by the sellers of the mortgages or shortcomings or failures in our internal processes or systems. We are not obligated to update or correct the SCS or SDS for any security. The SCS and SDS for our securities are generally subject to the same risks and limitations as our pool- and loan-level data, as described in the sections titled “Monthly Reporting of Pool-Level Data” and “Loan-Level Data” in the offering circulars for our UMBS, MBS and PCs.

The SCS and SDS for any security are based on the characteristics of the mortgages underlying such security at the time of Freddie Mac’s acquisition of such mortgages. It is possible that the SDS and SDS for a security could change significantly over the term of the security.

This is not an offer to buy or sell any Freddie Mac securities. Offers for any given security are made only through applicable offering circulars and related supplements, which incorporate Freddie Mac’s most recent Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC); all other reports Freddie Mac files with the SEC pursuant to Section 13(a) of the Securities Exchange Act of 1934 (Exchange Act), excluding any information "furnished" to the SEC on Form 8-K; and all documents that Freddie Mac files with the SEC pursuant to Sections 13(a), 13(c) or 14 of the Exchange Act, excluding any information “furnished” to the SEC on Form 8-K.
