To capture maximum capital and balance sheet efficiencies, all SFTs are required to be executed as overnight term transactions. However, to minimize the operational burden of settling overnight obligations, settlements are allowed to pair off daily against new activity, with NSCC calculating and processing Price Differential, that is price differences/mark-to-market (MTM), that are created by the daily pair off. NSCC novates and guarantees the off-leg/return of an SFT (i) when delivery of underlying SFT security completes at DTC, (ii) at the point of validation in the case of a bilaterally settled SFT or an SFT with a Sponsored Member client or (iii) when the daily pair-off occurs, in the case of a rolled SFT.
