(1)Value of our investments in VIEs, as presented in this table, represents the fair value of our economic interests in the consolidated VIEs that we account for under the CFE election. CAFL includes BPL term loan securitizations we account for under the CFE election and two BPL bridge loan securitizations for which we did not make the CFE election. As of September 30, 2023 and December 31, 2022, the fair value of our interests in the CAFL Term securitizations were $316 million and $304 million, respectively, and the remaining values were associated with our interests in the CAFL Bridge securitizations, for which the ABS issued is carried at amortized historical cost. At December 31, 2022, Freddie Mac SLST includes securitizations we account for under the CFE election and also includes ABS issued in relation to a re-securitization of the securities we own in the consolidated Freddie Mac SLST VIEs, that we account for at amortized historical cost. In January 2023, we called the Freddie Mac SLST re-securitization and paid off the associated outstanding ABS issued. As of September 30, 2023 and December 31, 2022, the fair value of our interests in the Freddie Mac SLST securitizations accounted for under the CFE election was $256 million and $323 million, respectively, with the difference reflected in the December 31, 2022 table above due to ABS issued and carried at amortized historical cost. The following tables present income (loss) from these VIEs for the three and nine months ended September 30, 2023 and 2022. Table 4.2 – Income (Loss) from Consolidated VIEs

(1)Maximum loss exposure from our involvement with unconsolidated VIEs pertains to the carrying value of our securities and MSRs retained from these VIEs and represents estimated losses that would be incurred under severe, hypothetical circumstances, such as if the value of our interests and any associated collateral declines to zero. This does not include, for example, any potential exposure to representation and warranty claims associated with our initial transfer of loans into a securitization.
