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

In 2024, Switzerland recorded 17,036 corporate bankruptcies – a 13.2% jump from the previous year. The common thread through most of those failures was not one catastrophic quarter. It was a slow slide past two legally defined financial distress thresholds that the Swiss Code of Obligations addresses in precise, actionable terms: capital loss under Art. 725a CO and over-indebtedness under Art. 725b CO. Both provisions were substantially strengthened through the 2023 Swiss corporate law reform, and both remain among the most consequential legal triggers any Swiss SME director can hit – whether they see it coming or not.

This article explains how each threshold works, what the board of directors is required to do by law, and where Swiss SMEs reliably trip up.

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

Swiss company law defines three escalating levels of financial distress. Each level carries its own trigger point and its own legal obligations for the board. The architecture is intentional: obligations build on each other as a company descends the ladder, which means early inaction at the Art. 725a stage can translate into compounding exposure by the time Art. 725b is reached.

Capital Loss (Art. 725a CO)

Capital loss is triggered when a company's equity drops below 50% of the protected equity base. That base is the sum of three components: (i) share capital, (ii) the non-distributable portion of statutory capital reserves, and (iii) statutory retained earnings reserves. Only the non-distributable slice of statutory capital reserves counts toward this calculation. Any freely distributable reserves – for instance, the portion of capital reserves that exceeds 50% of nominal share capital – are excluded from the test.

When the most recent annual financial statements show the 50% threshold has been crossed, the board must take corrective action immediately. If those internal measures are not enough, it must call a general shareholders' meeting (GV/AGM) and put restructuring proposals to shareholders.

The Three Components of the Protected Equity Base

1. Share Capital

Share capital is the nominal value of every share registered in the Handelsregister. Market value does not enter this calculation, nor does the total cash a company has raised from investors. A company could attract CHF 50 million in a funding round, but if the new shares carry a nominal value of CHF 0.05 each, only that aggregate nominal figure counts toward share capital.

2. Statutory Capital Reserve: Non-Distributable Portion Only

This reserve accumulates the Agio – the spread between what investors paid per share and the share's nominal value. Following the 2023 reform, only the portion of statutory capital reserves up to 50% of share capital qualifies as legally protected and enters the Art. 725a test. Everything above that ceiling 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 holding CHF 5 million in statutory capital reserves against CHF 100,000 of share capital may count only CHF 50,000 – not the full CHF 5 million – in the protected equity base.

3. Statutory Retained Earnings Reserve

Under Art. 671 CO, 5% of annual profit must be allocated to this reserve until it and the statutory capital reserve together reach 50% of share capital. Only this formal legal reserve qualifies. Voluntarily retained earnings and accumulated profit carried on the balance sheet do not count.

The Formula

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

Capital loss is triggered when: Total equity < 50% x 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 Swiss cases of 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% x 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% x 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 sets a harder threshold: total liabilities exceed total assets, regardless of how equity is structured. If the board has "reasonable concern" this may be the case, it must prepare interim financial statements at going-concern values right away – and in most circumstances, at liquidation values too. If either set of statements confirms over-indebtedness, the board must notify the competent court, unless one of two legally valid exits is available:

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 audited interim statements become 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 exemption. They must appoint an approved auditor (Revisionsexperte), even if they would 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 instrument most frequently used to head off a mandatory court notification under Art. 725b CO. It is also the instrument most frequently misapplied.

Under the revised CO, a valid subordination must be unconditional and irrevocable for the entire period the company remains below its minimum required equity level. A subordination letter that permits the creditor to revoke it on notice, or that leaves out accrued interest, is legally defective. The 2023 reform expressly addressed this gap: interest on subordinated claims must now be included in the subordination – a departure from what was previously accepted practice.

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

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

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 the protected equity base. If share capital is CHF 100,000 and statutory reserves are CHF 50,000, the Art. 725a alarm should fire the moment equity drops below CHF 75,000. That trigger belongs in monthly management accounts, not as a year-end discovery from the auditor. 2. Appoint your auditor before a crisis, not during one. SMEs that have validly opted out of the limited statutory audit lose that exemption automatically the moment a capital loss or over-indebtedness situation arises. If equity is anywhere near the 50% 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 that 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 reaches 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 from the point at which the board knew – or should have known – that a threshold was breached. Signed, dated board minutes are the primary legal defence. Resigning from the board does not release a director from liability for omissions that occurred during their tenure.

Common Mistakes Swiss SMEs Make

1. Treating Art. 725a as a soft warning until Art. 725b arrives. Capital loss is not a preliminary advisory – it is a direct legal obligation trigger. Boards that note the 50% breach and defer action have already defaulted on their Art. 725a duties. Losses accumulating between the trigger date and the first documented board response fall squarely in personal liability territory. 2. Confusing equity with cash. A company that is profitable and cash-generating can still be in capital loss. Swiss SMEs in asset-heavy sectors – construction, manufacturing, hospitality – regularly 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 that gap. 3. Relying on an informal Rangrücktritt. An email from a shareholder indicating they will not seek repayment for now does not constitute a valid subordination. The agreement must be written, unconditional, irrevocable, and must explicitly include interest. Courts have consistently declined to accept informal arrangements. 4. Assuming GmbH partners carry 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 perspective, Art. 725a and Art. 725b are rarely pure legal problems in isolation – they are symptoms of a finance function that lacks real-time visibility into equity and liability positions. The Swiss SMEs that navigate these provisions without incident are almost always those running a structured monthly close, a rolling 13-week cash forecast, and board reporting that includes a one-page equity health check alongside the revenue figures.

The version of this story that ends worst is not the company that hits over-indebtedness and files promptly. It is the company where the board kept operating for months after the threshold was crossed, piling on new liabilities that became personal claims against individual directors. The structural fix is clear: governance that connects financial reporting to legal obligations in real time, and an independent CFO function with both the authority and the mandate to escalate early rather than manage 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.
