Capital Loss & Over-Indebtedness Under Swiss Law: What Every Director Must Know (Art. 725a & 725b CO)

Swiss bankruptcies hit a record 17,036 cases in 2024 – a 13.2% increase over the prior year. Behind most of those failures was not a single bad month; it was a quiet drift through two legally defined warning thresholds that the Swiss Code of Obligations has explicitly mapped out and assigned concrete board duties to: capital loss under Art. 725a CO and over-indebtedness under Art. 725b CO. Both provisions were significantly sharpened in the landmark 2023 Swiss corporate law reform, and they remain the most consequential articles any Swiss SME director can trigger – knowingly or not. This article covers both thresholds in full: how each is calculated, what the board of directors is legally required to do, and where Swiss SMEs consistently make avoidable and expensive mistakes.

How Art. 725a and Art. 725b Actually Work in 2026

The Swiss Code of Obligations defines three escalating levels of financial distress, each with its own legal trigger and board obligations. Understanding the architecture matters because the obligations compound as you descend the ladder.

Capital Loss (Art. 725a CO)

Capital loss is triggered when a company’s equity falls below 50% of the protected equity base – the sum of (i) share capital, (ii) the non-distributable portion of statutory capital reserves, and (iii) statutory retained earnings reserves. Only the non-distributable portion of statutory capital reserves counts. Any freely distributable reserves – for example, the portion of capital reserves exceeding 50% of nominal share capital – are excluded from the threshold test.

When the last annual financial statements show the 50% breach, the board must immediately take corrective measures; if those measures are insufficient, it must call a general shareholders’ meeting (GV/AGM) and propose restructuring steps.

The Three Components of the Protected Equity Base

1. Share Capital

Share capital is the nominal value of all shares registered in the Handelsregister – not the market value, and not the total cash raised from investors. A company can raise CHF 50 million in a capital round, but if the new shares have a nominal value of CHF 0.05 each, only the nominal total enters share capital.

2. Statutory Capital Reserve: Non-Distributable Portion Only

This reserve collects the Agio (the difference between what investors paid per share and the nominal value). After the 2023 reform, only the portion of statutory capital reserves up to 50% of share capital is legally protected and counts in the Art. 725a calculation. Anything above that level is freely distributable and excluded.

Rule: Non-distributable portion = the lower of (a) actual statutory capital reserve, or (b) 50% of share capital.

Example: a company with CHF 5 million in statutory capital reserves and CHF 100,000 in share capital can only count CHF 50,000 – not the full CHF 5 million.

3. Statutory Retained Earnings Reserve

Under Art. 671 CO, 5% of each year’s profit must be allocated here until this reserve plus the statutory capital reserve together reach 50% of share capital. Only this formal legal reserve counts – not voluntarily retained earnings, not accumulated profit carried forward on the balance sheet.

The Formula

Protected equity base = Share capital + non-distributable statutory capital reserve + statutory retained earnings reserve

Capital loss is triggered when: Total equity < 50% × protected equity base

Real Example: Meyer Burger Technology AG (31 December 2023)

Meyer Burger Technology AG is a Swiss solar technology company listed on the SIX Swiss Exchange. Its 2023 annual report disclosed a net loss of CHF 291.9 million, a going-concern risk, and a planned rights issue of CHF 200–250 million as the minimum condition for continued operations – making it one of the most publicly documented cases of a Swiss company managing acute financial distress under the revised CO framework.

Equity line item	CHF million
Share capital	179.861
Capital reserves (gross)	1,401.980
Treasury shares	–4.440
Reserve for share-based payments	7.670
Accumulated losses	–1,393.661
Total equity	191.410

Step 1 – Non-distributable capital reserve (capped): 50% × CHF 179.861 million = CHF 89.931 million. The gross capital reserve of CHF 1,401.980 million far exceeds the cap. Only CHF 89.931 million counts.

Step 2 – Statutory retained earnings reserve: Meyer Burger has sustained accumulated losses. Amount counted: CHF 0.

Step 3 – Protected equity base:

Component	CHF million
Share capital	179.861
Non-distributable statutory capital reserve	89.931
Statutory retained earnings reserve	0.000
Protected equity base	269.792

Step 4 – Art. 725a threshold: 50% × CHF 269.792 million = CHF 134.896 million

Step 5 – Test: Actual total equity CHF 191.410 million > threshold CHF 134.896 million. Result: No capital loss under Art. 725a at 31.12.2023. Buffer remaining: CHF +56.514 million.

Over-Indebtedness (Art. 725b CO)

Over-indebtedness is the harder threshold: total liabilities exceed total assets, regardless of equity structure. If the board has “reasonable concern” that this may be the case, it must immediately prepare interim financial statements at going-concern values and, in most cases, at liquidation values. If either confirms over-indebtedness, the board must notify the competent court – or use one of two legally permitted escape hatches:

1. Obtain a qualifying creditor subordination (Rangrücktritt) covering the shortfall.
2. Demonstrate a credible prospect that the over-indebtedness can be eliminated within 90 days from the date the audited interim statements are available.

Critical 2023 addition: companies in either a capital loss or over-indebtedness situation that had previously opted out of a limited statutory audit are no longer entitled to that opt-out. They must appoint an approved auditor (Revisionsexperte), even if they ordinarily qualify for opting out.

Art. 725a vs. Art. 725b: Trigger, Obligation, and Timeline

Criterion	Art. 725a – Capital Loss	Art. 725b – Over-Indebtedness
Trigger	Equity < 50% of protected equity base	Liabilities > Total assets
Who detects it	Annual (or interim) financial statements	Any “reasonable concern” – not just annual accounts
Board obligation	Take remedial measures; call GV if needed	Prepare dual interim statements immediately
Audit requirement	Mandatory limited audit applies	Mandatory limited audit applies
Court notification	Not required for Art. 725a alone	Required unless Rangrücktritt or 90-day cure applies
Grace period	No statutory deadline, but action must be “immediate”	90 days from availability of audited interim statements
Escape hatch	Recapitalise, restructure, or reduce share capital	Rangrücktritt or demonstrated 90-day cure
Risk if ignored	Personal liability under Art. 754 CO	Personal liability + criminal exposure
Applies to GmbH?	Yes	Yes

The Nuance Swiss SMEs Routinely Miss: The Rangrücktritt Rules

The Rangrücktritt (creditor subordination) is the most commonly used tool to avoid a mandatory court notification under Art. 725b CO. It is also the most commonly misapplied.

Under the revised CO, a valid subordination must be unconditional and irrevocable for the entire period the company remains below the minimum required equity level. A subordination letter that allows the creditor to revoke it on notice, or that excludes accrued interest, is legally defective. The 2023 reform explicitly closed this gap: interest on subordinated claims must also be included in the subordination – a change from prior practice.

The subordination must be in place and documented before or simultaneously with the filing of interim financial statements that disclose over-indebtedness. Retroactive or backdated agreements are inadmissible and expose board members to personal liability under Art. 754 CO.

In a documented Swiss SA case, directors who continued operations for eight months after over-indebtedness was apparent incurred an additional CHF 680,000 in liabilities – each of which became personal liability exposure. Under Art. 759 CO, any one liable director can be required to cover the entire amount of damages assessed.

Practical Steps for Swiss SMEs in 2026

1. Establish a real-time equity monitoring process. The 2023 reform explicitly requires the board to monitor solvency on a rolling basis – not just at year-end. Build a monthly dashboard that tracks equity as a percentage of protected equity. If your share capital is CHF 100,000 and statutory reserves are CHF 50,000, your Art. 725a alarm fires the moment equity drops below CHF 75,000. This should be a hard stop in your monthly management accounts, not a year-end surprise from your auditor.
2. Appoint your auditor before a crisis, not during one. SMEs that have validly opted out of the limited statutory audit lose that opt-out automatically once a capital loss or over-indebtedness situation exists. If you are anywhere near the 50% equity threshold, appoint an approved auditor (Revisionsexperte) now.
3. Prepare interim financial statements the moment “reasonable concern” arises. Art. 725b CO does not wait for the annual close. If management accounts in July show liabilities threatening to exceed assets, the board must act immediately. Prepare going-concern interim statements first; if those show no over-indebtedness and the going-concern assumption holds, liquidation-value statements can be waived. Document this decision in board minutes.
4. Structure any Rangrücktritt correctly. Obtain a formal, written subordination agreement that: (a) is unconditional and irrevocable, (b) covers both principal and accrued interest, and (c) remains effective until the company achieves adequate equity coverage. Have the document reviewed by a Swiss commercial lawyer before filing interim statements that rely on it.
5. Document every board resolution with timestamps. Personal liability under Art. 754 CO is assessed based on when the board knew – or should have known – that a threshold was breached. Signed, dated board minutes are your primary legal defence. If you resign from the board, you are not released from liability for omissions that occurred during your tenure.

Common Mistakes Swiss SMEs Make

1. Treating Art. 725a as a formality until Art. 725b arrives. Capital loss is not a soft warning – it is a legal obligation trigger. Boards that note the 50% breach but defer action have already defaulted on their Art. 725a duties. Any losses accumulated between the trigger and the board’s first documented response fall into personal liability territory.
2. Confusing equity with cash. A profitable company with strong receivables can be in capital loss without a single missed payroll. Swiss SMEs in asset-heavy sectors – construction, manufacturing, hospitality – frequently discover their equity position only through the annual audit. Monthly liquidity planning, as mandated by the 2023 reform under Art. 725 CO, is specifically designed to close this gap.
3. Relying on an informal Rangrücktritt. An email from a shareholder saying “I won’t ask for repayment for now” does not constitute a valid subordination. The agreement must be written, unconditional, irrevocable, and must explicitly include interest. Courts have consistently rejected informal arrangements.
4. Assuming GmbH partners have lower exposure than AG directors. All provisions of Art. 725–725c CO apply equally to the GmbH. Managing officers of a GmbH carry identical duties and identical personal liability exposure under Art. 754 CO as AG board members.

The CFO Perspective

From a fractional CFO‘s vantage point, Art. 725a and Art. 725b are not primarily legal problems – they are symptoms of a finance function that lacks real-time visibility. The Swiss SMEs that navigate these provisions successfully are almost always those with a structured monthly close, a rolling 13-week cash forecast, and a board that reviews a one-page equity health check alongside revenue figures.

The most damaging version of this story is not the company that hits over-indebtedness and files quickly – it is the company where the board continued operating for months after the threshold was crossed, incurring new liabilities that become personal claims against individual directors. The fix is structural: governance that connects financial reporting to legal obligations in real time, and an independent CFO function that escalates early rather than managing optics.

Frequently Asked Questions

What exactly is capital loss under Swiss law?

Capital loss (Kapitalverlust) under Art. 725a CO occurs when a company’s equity falls below 50% of its protected equity base – the sum of nominal share capital, non-distributable statutory capital reserves, and statutory retained earnings reserves. It is distinct from over-indebtedness: equity can still be positive, but if it is less than half the protected base, the legal obligations under Art. 725a are triggered.

What is the board required to do once capital loss is detected?

The board must immediately take measures to eliminate the capital loss. If internal measures – cost reductions, asset disposals, capital injection – are insufficient, the board must convene a general shareholders’ meeting (GV) and propose restructuring measures. Companies that had opted out of a limited statutory audit must also now appoint an approved auditor (Revisionsexperte).

Did the over-indebtedness rules change in 2023?

Yes. The 2023 Swiss corporate law reform introduced several changes to Art. 725b CO. The most material: liquidation-value interim statements can now be waived if going-concern statements show no over-indebtedness; the 90-day cure window was formally codified; and the Rangrücktritt must now explicitly cover interest, not just principal. The audit opt-out exemption for companies in capital loss or over-indebtedness was also removed.

How much equity does a Swiss SME need to avoid triggering Art. 725a?

It depends on share capital and reserve structure, not revenue. A GmbH with CHF 20,000 share capital and CHF 10,000 in non-distributable statutory reserves has a protected equity base of CHF 30,000 – Art. 725a triggers if equity falls below CHF 15,000. An AG with CHF 100,000 share capital and CHF 40,000 in qualifying reserves has a CHF 140,000 base; capital loss triggers below CHF 70,000 of equity.

How long does the board have to act once over-indebtedness is confirmed?

The board must prepare interim financial statements immediately upon reasonable concern. Once audited interim statements confirming over-indebtedness are available, there are two exits: a Rangrücktritt covering the shortfall, or a credible remediation plan eliminating the over-indebtedness within 90 days. If neither applies, court notification is mandatory without further delay.

Do these rules apply differently to a GmbH vs. an AG?

The substantive duties are identical. Art. 725a and 725b CO apply to both legal forms. A GmbH’s managing officers carry the same duties and personal liability exposure as AG board members under Art. 754 CO.

Can a director avoid personal liability by resigning?

No. Resignation does not release a director from liability for omissions that occurred during their tenure. A director who identifies a capital loss situation, fails to act, and then resigns can still face personal liability claims under Art. 754 CO for damages attributable to the period of inaction.

What if liquidity is a problem, not equity?

Liquidity risk and capital loss are two separate legal triggers. Under Art. 725 CO (revised 1 January 2023), the board has an explicit and ongoing duty to monitor the company’s solvency separately from the Art. 725a and 725b calculations – and must take measures as soon as imminent illiquidity (drohende Zahlungsunfähigkeit) becomes foreseeable. In practice, this means maintaining a rolling 12-month liquidity plan at all times.
