Part of credit and restructuring models, with the models, labs and guides around it.
What it does
The maintenance tests in a credit agreement, computed each period against their levels. Total net leverage is tested against a maximum that steps down as the loan seasons; interest cover is EBITDA over cash interest; fixed charge cover is EBITDA less capex and cash taxes, over cash interest plus scheduled amortisation. Each is also expressed as an EBITDA cushion, the share of EBITDA that could be lost before the test breaks, so the tightest test is visible at a glance and comparable across all three.
Where it lives
The same schedule in each model that carries it, with the rows to open. Open a model in the browser, go to the sheet, and click the lines.
- Assumptions, rows 42–44: Maximum total net leverage, Minimum interest cover, Minimum fixed charge cover
- Covenants, rows 6–8: Actual net leverage, Covenant maximum, Leverage headroom (EBITDA cushion)
- Covenants, rows 11–12: Actual interest cover, Interest cover headroom (EBITDA cushion)
- Covenants, rows 15–17: Fixed charges, Actual fixed charge cover, Fixed charge headroom (EBITDA cushion)
- Covenants, rows 20–22: Tightest EBITDA cushion, Tightest test, Covenant breach flag
What a reviewer looks for
- Ratios shown with no headroom.
- Fixed charges that leave out scheduled amortisation.
- Net leverage netting cash the agreement does not let you net.
