Risk assessment

Risk level: Severe (Covenant Breach Likely)

DSCR < 1.0 usually implies cash flow is insufficient to cover debt service.

How it works

  • EBITDA = revenue − operating costs.
  • DSCR = EBITDA ÷ annual debt service.
  • Cost shock increases operating costs and reduces EBITDA.
  • Lower DSCR increases covenant breach and refinancing risk.
