The SPV must be formed as a company or trust or other legal entity having no other business. In a Sukuk securitisation, the SPV must be organised, for example, as a Musharakah, Mudarabah or Wakalah, where the requirement of SPV having no other business applies. In the case of a Musharakah, there is a partnership contract with financial participation by the Sukuk investors. In the case of a Mudarabah structure, only the Sukuk investors participate with money as Rabb al-Mal, while the other party (i.e. the SPV) acts as the manager (as Mudarib) of the securitised assets. In the case of Wakalah, the SPV as an agent (Wakil) acts as the manager of assets on behalf of the Sukuk investors.
