What it means
Book net worth, the simple difference between total assets and total liabilities, is a legal fact rather than an economic one. It can be inflated by goodwill from an old acquisition, by capitalised development costs that may never earn a return, or by money owed to the business by its own directors.
Lenders discount all of it before deciding how much cushion really exists. At the same time, book net worth can understate the owner's commitment.
Many private companies are funded partly by shareholder loans, which sit in liabilities even though the owner has no realistic intention of demanding repayment ahead of the bank. When those loans are formally subordinated, the lender treats them as quasi-equity and adds them back.
Effective net worth is the result of both adjustments: tangible assets less real liabilities, plus subordinated owner funding. It usually appears inside loan agreements as the denominator of a leverage covenant, so the borrower must keep senior debt below some multiple of effective net worth.
Breaching that ratio can trigger a default even when the business is trading profitably. The practical consequence is that how you structure owner funding matters as much as how much you put in.
Cash injected as share capital and cash lent under a signed subordination deed count identically for covenant purposes, while cash lent on ordinary terms counts against you twice, adding to debt and doing nothing for net worth. A short legal document can therefore move a ratio by a full turn.
Definitions vary between lenders, which is the main trap. Some exclude all intangibles, others allow purchased goodwill but not internally generated brands, and some also deduct amounts owed by connected companies.
Always read the definition written into the specific facility agreement rather than assuming a standard formula.
In practice
Real-world examples.
Example
A family-owned engineering firm applies for a $1,500,000 equipment facility. The bank refuses until the founders sign a subordination deed over their $600,000 director loan, which lifts effective net worth enough to bring the leverage covenant within policy.
Example
A software company carries $1,800,000 of capitalised development costs on its balance sheet. Its lender excludes the entire amount when computing effective net worth, so the company negotiates a covenant based on recurring revenue instead of net worth.
Example
A wholesaler acquires a competitor and books $2,000,000 of goodwill. Book net worth jumps, but effective net worth is unchanged, and the acquirer discovers its borrowing headroom has not moved at all despite a much larger balance sheet.
Formula
Calculation
Effective Net Worth = (Total Assets - Intangible Assets) - Total Liabilities + Subordinated Shareholder Loans
Consider a distribution business with total assets of $4,200,000 and total liabilities of $2,900,000. Book net worth is $4,200,000 - $2,900,000 = $1,300,000.
Goodwill from an earlier acquisition accounts for $300,000 of those assets, so tangible net worth is $1,300,000 - $300,000 = $1,000,000. The founder has lent the company $450,000 under a deed subordinating the loan to the bank, so effective net worth is $1,000,000 + $450,000 = $1,450,000.
Now apply the covenant. Senior liabilities are the total liabilities less the subordinated loan: $2,900,000 - $450,000 = $2,450,000. Senior debt to effective net worth is $2,450,000 / $1,450,000 = 1.69 times, comfortably inside a 2.0 times covenant. Measured the naive way, total liabilities over tangible net worth would read $2,900,000 / $1,000,000 = 2.9 times and the company would look to be in breach.Case study
Seen in the real world.
Brackenfield Supply Company is a fictional distributor created to illustrate the point. Its statutory accounts showed net worth of $1,300,000, which the managing director considered healthy when he approached his bank for a larger overdraft.
The bank's credit team produced a different figure. It deducted $300,000 of goodwill left over from a small acquisition made four years earlier and arrived at tangible net worth of $1,000,000, against senior liabilities of $2,450,000. On that basis leverage looked far too high and the request was declined.
The turning point was a subordination deed. The managing director's $450,000 loan to the company was formally ranked behind the bank, which allowed it to be counted as quasi-equity and lifted effective net worth to $1,450,000. Leverage recalculated at 1.69 times, the facility was approved, and Brackenfield now reports effective net worth alongside statutory net worth in its monthly management pack so it never misjudges its position again.
Watch out
Common mistakes.
- Assuming effective net worth is just what the statutory accounts show. Lenders adjust for intangibles, connected-party balances and subordinated debt, and the adjusted figure is often materially different.
- Believing an informal promise not to withdraw a director loan counts. Only a signed subordination deed that ranks the loan behind the bank will normally be given credit.
- Treating goodwill from a genuinely successful acquisition as bankable net worth. It may reflect real value, but it cannot be sold separately in a distress scenario, which is exactly the scenario the measure is built for.
Questions
People also ask.
Is effective net worth the same as tangible net worth?
No, tangible net worth stops at removing intangibles, whereas effective net worth also adds back subordinated owner funding.
Does a subordinated loan still earn interest?
Usually yes, though many facility agreements block cash interest payments while the senior loan is outstanding, allowing the interest to roll up instead.
How often is the covenant tested?
Most facilities test quarterly against management accounts and annually against audited figures, and the tighter of the two definitions is the one that binds.
