Concerns (the will)
In a crisis, people retreat, protect their own area, or wait it out. Someone who fears for their job will not drive a hard measure forward. Leave those concerns unaddressed, and the list stays a list.

Corporate Insolvency in Germany: The Three Windows Before It's Too Late
From the outside a sudden event — from the inside the end of a process that began months or years earlier. Which window a company reaches decides its options.

From the outside, an insolvency looks like a sudden event. From the inside, it is almost always the end of a process that started months or years earlier. Liquidity tightened, the measures landed too late, and the room to maneuver kept shrinking until only one option was left.
This guide starts from a different question than the usual explainer. The point is not „what is insolvency". The point is: when did the company still have options, and why did it fail to use them? German insolvency law defines three thresholds, and each one marks a window with its own room for action. Act early and almost every option is still open. Act late and barely one remains.
What follows: how the three thresholds differ in law, which restructuring tools open in which window, and why the outcome is decided by execution, not by how well a company knows the statute.
01
What an insolvency actually is
In Germany, insolvency is an orderly court procedure for a company that can no longer meet its financial obligations. It is governed by the Insolvency Code (Insolvenzordnung, InsO). Its purpose is to balance the interests of creditors against the possible continuation of the business.
Still, the rule holds: the later the procedure begins, the narrower the room to act. That is why the three thresholds that precede it deserve a closer look.
02
The three thresholds: when insolvency looms
German law defines three states. They are not gradual shades of the same problem. They are legally distinct, and each triggers different duties.
| Imminent illiquidity | Over-indebtedness | Illiquidity | |
|---|---|---|---|
| Legal basis | § 18 InsO | § 19 InsO | § 17 InsO |
| Definition | The company will probably be unable to meet payments (forecast over 24 months) | Assets no longer cover liabilities, and no positive going-concern prognosis exists | The company can no longer meet payments that are due |
| What it triggers | Right to file voluntarily, access to pre-insolvency tools | Duty of management to file | Duty to file, short deadline, personal liability risk |
| Filing | Right | Duty | Duty |
The decisive difference is the sequence. Imminent illiquidity is a pre-insolvency state: the company sees the problem coming but still has substance and time. Here, filing is a right, not an obligation. With over-indebtedness and illiquidity, it becomes a duty. Management must file without culpable delay, or it faces personal liability and criminal consequences. Not knowing the rules is no defence.
For corporations (GmbH, AG), liability is in principle limited to company assets. That limit falls away when management breaches statutory duties, for example by delaying a required insolvency filing. At that point, personal liability applies.
03
The restructuring-window model
The three thresholds can be read as three windows. Each window stands for a room of available actions, and that room shrinks with every step down. The runway below shows how the available room narrows as a company moves from § 18 to § 19 to § 17.
The restructuring-window model
- Imminent illiquidity Right90% room to act
- StaRUG
- Restructuring plan
- Stabilisation order
- Over-indebtedness Duty45% room to act
- Self-administration
- Protective shield
- ESUG tools
- Illiquidity Duty12% room to act
- Insolvency plan
- Administrator
Three statutory thresholds, ordered from the most room to act to the least: § 18 — Imminent illiquidity: 90% room to act. Right (Right to file voluntarily). Tools: StaRUG, Restructuring plan, Stabilisation order. Pre-insolvency: the problem is foreseeable, substance and time remain. Filing is a right, not a duty. § 19 — Over-indebtedness: 45% room to act. Duty (Duty to file). Tools: Self-administration, Protective shield, ESUG tools. Assets no longer cover liabilities. The duty to file applies and the room to act narrows. § 17 — Illiquidity: 12% room to act. Duty (Duty to file · short deadline). Tools: Insolvency plan, Administrator. Payments that are due can no longer be met. Usually only the regular procedure remains; the administrator takes control.
Window 1 – Imminent illiquidity. The toolkit is at its fullest here. Under StaRUG (the corporate stabilization and restructuring law, in force since 2021 [1]), a company can restructure outside of insolvency: a restructuring plan, negotiations with creditors, court-ordered stabilization measures. Management keeps control, and ideally the market never notices.
Window 2 – Over-indebtedness. The room narrows, and the duty to file applies. Now the tools introduced by ESUG (the 2012 law easing corporate restructuring) come into play. Self-administration (Eigenverwaltung) lets management stay at the helm. The protective shield procedure (Schutzschirmverfahren) grants up to three months under court protection to develop a restructuring plan, shielded from enforcement.
Window 3 – Illiquidity. The last window. Usually only the regular insolvency procedure with an administrator remains. Restructuring is still possible, for instance through an insolvency plan. But the administrator takes control, and the original management's room to act is minimal.
One tool spans all three windows: the restructuring opinion under IDW S6, the German auditors' standard. It analyzes the causes of the crisis, assesses whether the company can be restructured, and proposes concrete measures. A positive opinion strengthens creditor confidence and is often a precondition for their support. The earlier it exists, the more windows remain open.
The logic of the model is clear. The value lies not in knowing the instruments, but in being able to deploy them early enough. And that depends on whether a company recognizes its situation in time and makes its measures land in time.
04
Why companies miss the early window
This is the real finding. Companies rarely slide from Window 1 to Window 3 because they lack legal knowledge. They slide because the restructuring measures fail to land in time.
The IDW S6 opinion is in hand, the list of measures exists, the instruments are known. And still the impact evaporates. Three places are responsible, and none of them is about statutes. We group them in the 3C model: Concerns, Competencies, Coordination.
The 3C model
Competencies (the ability)
Restructuring demands skills that the day-to-day rarely requires: liquidity steering, hard prioritization, creditor negotiation. Where they are missing, execution stalls exactly where it matters most.
Coordination (working together)
A crisis multiplies the number of people involved, and with it the cost of alignment. Without a shared data base, the restructuring team, the supervisory board and the banks work from different pictures of the situation. Decisions slip while the window closes.
Most tools on the market address only the third C, coordination, and often only as a task list. The first two, the will and the ability of the people involved, go unattended. Yet that is precisely where it is decided whether a restructuring uses the early window or lets it pass. More on this in our guide to corporate restructuring.
05
Degree of implementation: how to tell whether a measure is really working
There is a reliable signal for whether a company can hold the early window: the honesty of its measure status.
In many crisis programs, the status of a measure is dressed up in the steering meeting. „On track" sits in the report until the quarter ends and the expected liquidity has not arrived. By then, Window 1 is often already shut.
The degree of implementation (Härtegrad) breaks that pattern. It describes the maturity of a measure along clear stages, from idea through concept and execution to cash-effective realization. A measure counts toward impact only once it has demonstrably reached the next stage. That makes visible the difference between a measure that is planned and one that actually frees up liquidity.
- 1 Idea
- 2 Concept
- 3 Execution
- 4 Cash-effective realization
A measure counts toward impact only once it has demonstrably reached the next stage.
In a restructuring, that difference is existential. It decides whether the going-concern prognosis, which co-determines Window 2, is credible. How measures can be tracked from idea to bankable P&L impact is shown in our guide to measuring transformation impact.
06
Early warning: what the cockpit has to show
A company that wants to reach Window 1 needs a picture of its situation that shows early and honestly where it stands. The classic warning signs are well known:
The classic warning signs
-
recurring late payments
-
persistent liquidity gaps
-
rising debt without matching revenue
-
harder access to credit
-
the loss of important customers
The problem is rarely that these signals are absent. The problem is that they converge too late. Liquidity planning sits in one spreadsheet, the measure status in another, the bank report in a third. By the time someone assembles the full picture, the window has shifted.
The lever is transparency in real time. A shared data base, where liquidity, measure status and degree of implementation come together, turns early warning from a monthly hindsight exercise into continuous steering. This matters, because the market is tightening: in 2025, German courts registered 24,064 corporate insolvencies, up 10.3 percent on the prior year, after increases of more than 20 percent in each of the two years before. Creditor claims totaled around 47.9 billion euros [2].

Conclusion
Insolvency is not a fate that strikes a company. It is the result of a process in which windows of action passed unused. German law keeps instruments ready for every window, from StaRUG through self-administration to the insolvency plan. But which window a company reaches does not depend on how well it knows the statute.
It depends on whether the restructuring measures land in time. And that is decided in three places: whether the people involved want to, whether they can, and whether they work together. That is the real work behind every successful turnaround.
ChangeMaker® is the program platform that makes exactly this work steerable: a shared data base for liquidity, measures and degree of implementation, so the restructuring team, the supervisory board and the banks all see the same honest status at any time.

Frequently asked questions
What is the difference between illiquidity and over-indebtedness?
Illiquidity (§ 17 InsO) means a company can no longer meet payments that are due. Over-indebtedness (§ 19 InsO) means liabilities exceed assets and there is no positive going-concern prognosis. Both trigger a duty to file for insolvency.
What is imminent illiquidity?
Imminent illiquidity (§ 18 InsO) applies when a company will probably be unable to meet its payments within the next 24 months. It entitles management to file voluntarily and opens access to pre-insolvency restructuring tools such as StaRUG. There is no duty to file at this stage yet.
Does insolvency mean the end of the company?
No. The insolvency procedure is explicitly designed to allow restructuring. Through an insolvency plan or self-administration, a company can be reorganized and continued. The earlier the procedure begins, the more room there is to keep the business going.
What is the difference between StaRUG and the protective shield procedure?
StaRUG enables restructuring outside of insolvency, at the stage of imminent illiquidity. The protective shield procedure is a tool within insolvency law (introduced via ESUG) that applies at imminent illiquidity or over-indebtedness and grants up to three months of court-protected time to develop a restructuring plan.
How can insolvency be avoided?
By using the early window: recognize the crisis early, prepare a restructuring opinion (IDW S6), deploy the right instruments, and above all make the restructuring measures land in time. The most common reason for a missed window is not a lack of legal knowledge, but execution that delivers too late.
