Sukuk can be issued through various securitization structures. Securitization involves pooling assets and repackaging them into marketable securities known as sukuk. A special purpose vehicle (SPV) is typically used to hold the assets and issue the sukuk. The sukuk represent undivided ownership interests in the underlying assets, with profits distributed from the assets' revenue. Common asset-based sukuk include those backed by murabahah contracts, ijarah contracts through asset sale-leaseback, and receivables. The SPV provides bankruptcy protection for investors if the originator entity encounters financial problems.
