Syfrets Participation Bond Managers Ltd acted as the manager of participation bond schemes under the Participation Bonds Act 55 of 1981. Due to timing mismatches between borrowers and investors, Syfrets frequently advanced its own funds into participation bonds on a temporary basis until other participants could be found or to cover shortfalls caused by withdrawals. At the end of each tax year, substantial amounts of Syfrets’ own money were tied up in such participations. Syfrets contended that these participations constituted its trading stock for purposes of the Income Tax Act 58 of 1962, entitling it to deductions under s 11(a) and valuation adjustments under s 22 for alleged diminution in value.
