Large Corporate debt-raising requirement: mandated minimum issuance through debt securities over three-year block, with incentives and penalties. Entities meeting listing, borrowing and credit rating thresholds are designated as Large Corporate. Such LCs must raise at least 25% of their qualified borrowings through issuance of debt securities, with compliance assessed over a contiguous three year block beginning in the year following identification. Surplus issuance yields reductions in listing fees and credits against Core SGF contributions; shortfalls trigger additional SGF contributions. Stock exchanges and the LPCC are responsible for identification, calculation, notification and systems implementation; transitional dispensations and effective dates are specified.
