Limited and unlimited liability

Unlimited liability

Sole traders and ordinary partners have unlimited liability: if the business cannot pay its debts, the owners' personal assets (house, car, savings) can be taken to pay them. There is no legal separation between owner and business.

• Advantages: easy to set up with no legal formalities; privacy of accounts; lenders may take the owner's commitment seriously.
• Disadvantages: huge personal risk, which can deter people from starting businesses or taking risks.

Limited liability

Shareholders of companies (Ltd and plc) have limited liability: the most they can lose is the amount they invested in shares. The company is a separate legal entity, so its debts are its own.

• Advantages: owners' personal assets are protected; it encourages investment and enterprise; easier to attract shareholders.
• Disadvantages: more paperwork and public accounts; suppliers and lenders face more risk, so they may want personal guarantees from directors, charge higher interest or offer less trade credit to small companies.

Liability and finance

• Unlimited liability businesses rely on owner's capital, retained profit, family and friends, bank loans and overdrafts (often secured on the owner's home), trade credit, leasing, grants and crowd funding. They cannot issue shares.
• Limited liability businesses can also sell shares (privately for an Ltd, to the public for a plc), and attract business angels and venture capital who want equity. Lenders may still ask small company directors for a personal guarantee, which removes the protection for that loan.

Worked example

A sole trader's business fails owing $70,000. Its assets are sold for $25,000. What happens to the remaining debt? How would this differ for an Ltd?

1. Remaining debt = 70,000 - 25,000 = $45,000
2. Sole trader: unlimited liability, so the owner must pay the $45,000 from personal assets.
3. Ltd: shareholders lose only what they invested in shares; the creditors bear the remaining loss (unless a director gave a personal guarantee).

Answer: The sole trader is personally liable for $45,000; Ltd shareholders would not be.

2. A shareholder bought 2,000 shares at $3 each in an Ltd that collapses with debts of $1 million. What is the most the shareholder can lose?

3. Which owner has unlimited liability?
   • A sole trader
   • A shareholder in a plc
   • A shareholder in an Ltd
   • A business angel holding shares
   Show answer

   A sole trader. Sole traders are not separate from their business.

4. Why might a bank ask the director of a small Ltd for a personal guarantee?
   • Because companies cannot borrow money
   • To give the director limited liability
   • Because the law requires it for every loan
   • Because limited liability means the bank could not otherwise pursue the director's personal assets
   Show answer

   Because limited liability means the bank could not otherwise pursue the director's personal assets. A guarantee puts the director's own assets back at risk for that loan.

5. How does limited liability benefit the economy as a whole?
   • It guarantees that companies repay their debts
   • It encourages people to invest in and start businesses because their risk is capped
   • It removes the need for banks
   • It raises tax revenue directly
   Show answer

   It encourages people to invest in and start businesses because their risk is capped. Capped risk encourages enterprise and investment.

6. Which source of finance is available to a private limited company but not to a sole trader?
   • A bank overdraft
   • Trade credit
   • A government grant
   • Selling shares
   Show answer

   Selling shares. Share capital needs a company.

7. Define limited liability.
   Show answer

   Limited liability means shareholders can lose no more than the amount they invested in the business; their personal assets are protected if the business fails.. Owners can only lose what they invested; personal assets are safe.
