A Special Purpose Entity (“SPE”) is an entity designed to fulfill a specific limited purpose of the company that organized it, and a SPE is frequently used for the purpose of securitizing, or re-securitizing, financial assets. SPEs are typically structured as pass through entities that receive principal and interest on the underlying collateral and distribute those payments to certificate holders. As a consequence of their purpose and design, SPEs are typically VIEs.

As further discussed in Notes 2, 5 and 6, the Company has evaluated its investments in Multi-Family MBS and Non-Agency RMBS and has determined that they are VIEs. The Company has then undertaken an analysis of whether it is the primary beneficiary of any of these VIEs, and has determined that it is the primary beneficiary of the FREMF 2011-K13 Trust, FREMF 2012-KF01 Trust and CSMC 2014-OAK1 Trust. Accordingly, the Company consolidated the assets, liabilities, income and expenses of these trusts in its financial statements as of and for the periods ending March 31, 2018 and December 31, 2017. However, the assets of each of the trusts are restricted, and can only be used to fulfill the obligations of the respective trusts. Additionally, the obligations of each of the trusts do not have any recourse to the Company as the consolidator of the trusts. The Company has elected the fair value option in respect of the assets and liabilities of the trusts.
