Many feel that issuance of bonds by an SME is another viable method of raising debt. However, Shariah does not permit issuance of fixed-income interest-bearing bonds, so sukuk are Shariah-compliant alternative to conventional bonds. They involve tangible assets in which the bondholder is given ownership interest and, for instance, is permitted to collect rent as profit. Sukuk can be structured in many different ways depending on the borrower’s need for raising debt, for example, sukuk al Ijara is used for funding asset acquisition and sukuk al Istisna is used for financing projects of varying scale. Proponents of sukuk often overlook the prohibitive nature of sukuk in the context of SMEs, for example, documentation for issuance of sukuk is not available off-the-shelf and preparation of custom documentation is expensive and time consuming. SMEs would often require a lender to underwrite subscription of sukuk, as public subscription would be unlikely in the absence of sound credit rating of the sukuk - credit rating agencies are reluctant to rate a Sukuk issue by an SME. Therefore, a sukuk issue is not a commercially viable option for SMEs to raise debt.
