What it means
Every company funded with a mix of debt and equity has an implied queue for repayment, often called the capital structure or the waterfall. Senior debt sits at the top of that queue, and everything below it only gets paid once the senior lenders are made whole.
Priority comes from two things working together: the contract and the collateral. Senior lenders normally hold security over the company's assets and also sign an intercreditor agreement in which junior lenders formally agree to wait their turn.
Because their downside is protected, senior lenders accept lower returns. It is common to see senior facilities priced several percentage points below subordinated debt for the same borrower, which is precisely why companies use senior debt for as much of their borrowing as lenders will allow.
The price of that cheap money is control. Senior loans come with covenants that cap total borrowing, require minimum earnings or cash cover, restrict dividends and asset sales, and give the lender the right to demand repayment if a test is breached.
Lenders size senior debt against earnings rather than assets alone. A senior leverage ratio of two to three times earnings before interest, tax, depreciation and amortisation is a typical comfort zone for a stable business, with more allowed where cash flows are highly predictable.
In practice
Real-world examples
Example 1
A manufacturer refinances with a $20,000,000 senior term loan at 6.5% secured over its plant and receivables, replacing a patchwork of equipment leases at higher rates. The covenant package caps total leverage at three times EBITDA and blocks dividends if cover falls below that.
Example 2
A private equity buyer funds an acquisition with $45,000,000 of senior debt, $15,000,000 of subordinated debt and $40,000,000 of equity. The senior tranche amortises over seven years while the subordinated layer is interest-only with a bullet repayment at the end.
Example 3
A retailer breaches a senior covenant after a weak Christmas, and the bank waives the breach in exchange for a fee, a higher margin and monthly rather than quarterly reporting. The junior lender has no equivalent right to intervene and can only watch.
Think of it
Senior debt is like having a VIP ticket at a concert. If the venue has to close early, VIP ticket holders get their refunds first, while standard ticket holders have to wait to see if any money is left over.
Formula
Calculation
Senior leverage ratio = senior debt / EBITDA
Recovery in liquidation = amount available at each level of the waterfall
A distribution company generates EBITDA of $3,200,000 and carries $8,000,000 of senior bank debt plus $5,000,000 of subordinated notes. Senior leverage is 8,000,000 / 3,200,000 = 2.5 times, while total leverage is 13,000,000 / 3,200,000 = 4.06 times.
Suppose the business later fails and its assets are sold for $12,000,000 after costs. The senior lender is paid first and recovers its full $8,000,000, a 100% outcome, leaving 12,000,000 - 8,000,000 = $4,000,000 for the next layer.
The subordinated noteholders are owed $5,000,000 but only $4,000,000 remains, so they recover 4,000,000 / 5,000,000 = 80% of their money and take a $1,000,000 loss. Shareholders receive nothing, which is exactly what the ordering is designed to produce. The 80% recovery is also why those notes were priced at 12% while the senior facility sat at 7%.Case study
Seen in the real world
Ridgeway Components is an illustrative, fictional automotive parts supplier that funded a factory expansion with $8,000,000 of senior bank debt at 7% and $5,000,000 of subordinated notes at 12%. Its EBITDA of $3,200,000 supported senior leverage of 2.5 times, comfortably inside the bank's three times limit.
When its largest customer moved production overseas, EBITDA halved to $1,600,000 and senior leverage doubled to 8,000,000 / 1,600,000 = 5.0 times, breaching the covenant immediately. The bank took control of the process, forced a sale of the business, and recovered its full $8,000,000 from $12,000,000 of net proceeds. The subordinated holders collected the remaining $4,000,000 against $5,000,000 owed and the founders, who held all the equity, received nothing.
The fictional lesson is that seniority is not a technicality buried in a loan agreement. It decides who controls the outcome when things go wrong, and it decides who absorbs the loss.
Watch out
Common mistakes
- Assuming senior debt is safe for the borrower because it is cheap, when its covenants are usually the tightest constraint on how the business can be run.
- Confusing seniority with security, when a loan can be senior by contract without holding a claim over any specific asset.
- Measuring capacity on total debt alone and ignoring the senior leverage test, which is often the covenant that actually bites first.
Questions
People also ask
Why is senior debt cheaper than other borrowing?
Because it is repaid first and usually secured, so the lender's expected loss is far lower and it accepts a smaller return.
Can a company have more than one senior lender?
Yes, and they typically share security and proceeds proportionally under an intercreditor agreement that sets out the ranking.
What sits below senior debt?
Subordinated or mezzanine debt, then preference shares, then ordinary equity, each ranking behind the layer above it.
