Transaction Summary

The WI K-Deal certificates represent the beneficial ownership interest in the trust, primary assets of which will be cash assets related to each class of WI certificates, and right to performance of Freddie Mac's obligations under a forward contract. The forward contract provides noteholders the option to exchange the WI certificates any time after the subsequent transfer date for their proportionate share of newly-issued Freddie Mac structured pass-through certificates (SPCs) from a Freddie Mac K-series deal.

After the subsequent transfer date, payments received on each corresponding SPC class will be passed through to the holders of the related WI certificates. If Freddie Mac does not deliver the SPCs, then the WI classes would be redeemed and Freddie Mac would pay a yield maintenance amount. If Freddie Mac delivers the SPCs with an outstanding principal balance that is less than the WI certificate balance, then it would refund the difference to certificate holders and pay a partial yield maintenance amount. Alternatively, holders may elect not to exchange the WI certificates and simply hold them to maturity.

Freddie Mac will guarantee certain payments of interest, principal and yield maintenance on the WI certificates prior to the subsequent transfer date as well as timely payment of interest and ultimate payment of principal received on the related K-Deal SPCs following the subsequent transfer date. Freddie Mac will act as depositor, trustee, administrator and guarantor of the trust.

KEY RATING DRIVERS

Linkage to Public Rating: The rating and Outlook for the A-2 certificates are directly linked to the rating and Outlook of Freddie Mac, the guarantee provider. A change in Fitch's assessment of the rating and Outlook of Freddie Mac would automatically result in a change in the rating and Outlook on the A-2 certificates. In addition, any change in Fitch's view on the guarantee may result in a downgrade of the notes.

Freddie Mac's Long-Term Issuer Default Rating (IDR) is directly linked to the Long-Term IDR of the U.S. sovereign, and the rating will continue to move in tandem. Therefore, the Negative Outlook on Freddie Mac's IDR stems from Fitch's Negative Outlook on the U.S. sovereign.

RATING SENSITIVITIES

Factors that could, individually or collectively, lead to negative rating action/downgrade:

A downgrade of the U.S. sovereign's Long-Term IDR would result in a downgrade of Freddie Mac's Long-Term IDR.

Fitch has revised its global economic outlook forecasts as a result of the war in Ukraine and related economic sanctions. Downside risks have increased and, therefore, Fitch has published an assessment of the potential rating and asset performance impact of a plausible, albeit worse than expected, adverse stagflation scenario on Fitch's major structured finance and covered bond subsectors ('What a Stagflation Scenario Would Mean for Global Structured Finance').

Fitch expects the North American CMBS sector in the assumed adverse scenario to experience virtually no impact on ratings performance, indicating very few rating or Outlook changes. Fitch expects the asset performance impact of the adverse case scenario to be more modest than the most stressful scenario shown above, which assumes a further 30% decline from Fitch's NCF at issuance.

Factors that could, individually or collectively, lead to positive rating action/upgrade:

An Outlook revision back to Stable from Negative would occur if the U.S. sovereign's Outlook is revised back to Stable from Negative.

Best/Worst Case Rating Scenario

International scale credit ratings of Structured Finance transactions have a best-case rating upgrade scenario (defined as the 99th percentile of rating transitions, measured in a positive direction) of seven notches over a three-year rating horizon; and a worst-case rating downgrade scenario (defined as the 99th percentile of rating transitions, measured in a negative direction) of seven notches over three years. The complete span of best- and worst-case scenario credit ratings for all rating categories ranges from 'AAAsf' to 'Dsf'. Best- and worst-case scenario credit ratings are based on historical performance.

PUBLIC RATINGS WITH CREDIT LINKAGE TO OTHER RATINGS

REPRESENTATIONS, WARRANTIES AND ENFORCEMENT MECHANISMS

A description of the transaction's representations, warranties and enforcement mechanisms (RW&Es) that are disclosed in the offering document and which relate to the underlying asset pool was not prepared for this transaction. Offering Documents for this market sector typically do not include RW&Es that are available to investors and that relate to the asset pool underlying the trust. Therefore, Fitch credit reports for this market sector will not typically include descriptions of RW&Es.

ESG Considerations
