## Classifying Firms

Firms are classified along four independent axes, and every combination exists. You must classify along each axis separately.

**By size** (EU employee headcount):
| Class | Employees |
| --- | --- |
| Micro | < 10 |
| Small | 10–49 |
| Medium | 50–249 |
| Large | 250+ |

Micro, small, and medium firms are **SMEs**: over 99% of all EU businesses.

**By sector**: primary (extracting: farming), secondary (transforming: manufacturing), and tertiary (services: banking).

## Legal Form & Trade-offs

**By ownership**: private (investors), public (state), or mixed.

**By legal form**:
- **Sole proprietorship**: one owner. Has **unlimited liability**: personal assets answer for business debts.
- **Partnership**: several owners sharing management and unlimited liability.
- **S.L.**: capital in participations; owners risk only invested capital.
- **S.A.**: capital in freely transferable shares.

**Key trade-off**: Unlimited-liability forms are simple to create but risk personal wealth. Limited liability protects personal assets, requiring higher formalities.

**Common pitfall**: In economics, **public ownership** means owned by the state, not a stock-listed company.

## Practice questions

7 of this lesson's 14 practice questions, with answers. The full set is in the app.

### 1. Two friends start a company and choose an SL over a partnership even though the paperwork is heavier. What are they buying?

A. The right to hire employees, which partnerships cannot do
B. A legal wall between company debts and personal assets
C. Lower tax rates on profits than a partnership would pay
D. Protection from paying the company's debts at all, including from company funds

**Answer:** B. A legal wall between company debts and personal assets

**Why:** Incorporation invents a second person who owns the debts, so the founders risk what they put in and no more. Option 4 confuses the wall's two sides, the company still pays from its own funds until they run out. That bounded downside is what makes outside investment thinkable at all.

### 2. Which statements about SMEs in the European Union are correct?

A. They make up over 99% of all EU businesses
B. The size classes use employee headcount thresholds of 10, 50, and 250
C. They include micro, small, and medium-sized firms
D. A firm with 300 employees still counts as an SME

**Answer:** A. They make up over 99% of all EU businesses; B. The size classes use employee headcount thresholds of 10, 50, and 250; C. They include micro, small, and medium-sized firms

**Why:** At 250 employees a firm leaves the SME class, 300 employees is large. The rest are the SME definition itself.

### 3. A firm can be classified by size, sector, ownership and legal form at the same time. Why are these four axes rather than one scale?

A. Because size determines the other three once it is known
B. Because each axis applies to a different country’s firms
C. Because they are independent axes answering different questions
D. Because European law requires firms to be reported on exactly four dimensions

**Answer:** C. Because they are independent axes answering different questions

**Why:** Independent axes carry independent information. Collapsing them into one ranking would lose exactly what makes the classification useful, that a firm can be small and public, or huge and family-held.

### 4. In an S.L., a shareholder who invested 5,000€ can lose at most 5,000€ if the company goes bankrupt.

**Answer:** True

**Why:** Limited liability caps each owner’s loss at their contribution, the company’s debts belong to the company, not to its owners.

### 5. Complete the statement about legal forms.

**Answer:** A sole proprietorship exposes the owner to **unlimited** liability, while an S.L. caps losses at the capital **contributed**.

**Why:** Unlimited liability reaches personal assets; in an S.L. only the contributed capital is at risk.

### 6. Two firms make the same product with the same headcount, one as an S.L. and one as an S.A. Why does that difference matter to an outside investor?

A. Because the S.A.'s shares move freely and the S.L. restricts them
B. Because the S.A. is required to be larger and so is the safer investment
C. Because the S.L. cannot distribute dividends to outside investors
D. Because only the S.A. offers limited liability to its owners

**Answer:** A. Because the S.A.'s shares move freely and the S.L. restricts them

**Why:** Legal form governs transferability, not size or liability. The S.A. is built for capital that must be able to leave; the S.L. for a closed group that wants control over who joins.

### 7. A sole proprietor’s café fails owing 60,000€ the business cannot pay. What happens?

A. Creditors can pursue the owner’s personal assets for the full debt
B. Creditors can claim at most the capital originally invested
C. The state automatically covers unpaid business debts
D. The debt vanishes when the business closes

**Answer:** A. Creditors can pursue the owner’s personal assets for the full debt

**Why:** A sole proprietorship has no legal wall between owner and business: personal savings, car, even home can answer for the 60,000€. That risk is precisely what limited-liability forms were invented to cap.
