Business Structure – Business Ownership

Objective

To understand the concepts of unlimited liability and limited liability, to recognise the full range of business‑ownership forms covered by the Cambridge International Business (9609) syllabus, and to appreciate why the choice of ownership and liability matters for owners, investors and the wider economy.

1. Economic Sectors – Why the Sector Matters

Businesses operate in four broad economic sectors:

  • Primary: extraction of natural resources (e.g., farming, mining).
  • Secondary: manufacturing and construction – turning raw materials into finished goods.
  • Tertiary: services such as retail, finance, education and health.
  • Quaternary: knowledge‑based activities – research, IT, consultancy.

Each sector has different capital requirements, risk profiles and regulatory environments, which influence the most suitable form of ownership. For example, a small family farm (primary) often remains a sole trader, whereas a high‑tech software start‑up (quaternary) may choose a private limited company to attract venture capital.

2. Liability – The Core Distinction

2.1 Unlimited Liability

  • Definition: Owners are personally responsible for all debts and obligations of the business. Creditors can claim the owners’ personal assets (house, car, savings) if the business cannot meet its liabilities.
  • Applies to: Sole traders and general partnerships.
  • Key features:
    • Business is not a separate legal entity – the owner and the business are the same.
    • Full control for owners.
    • Full financial risk – personal assets at stake.

2.2 Limited Liability

  • Definition: Owners’ financial responsibility is limited to the amount they have invested (share capital or partnership contribution). Personal assets are protected.
  • Applies to: Private limited companies (Ltd), public limited companies (PLC), limited‑liability partnerships (LLP) and most social‑enterprise structures.
  • Key features:
    • The company is a separate legal entity – it can own property, sue and be sued in its own name.
    • Risk to owners is capped at the amount invested.
    • Facilitates larger‑scale investment and easier access to finance.

2.3 Why Liability Matters

Liability determines the level of financial risk for owners, which in turn affects:

  • Access to finance: Lenders are more willing to provide large loans to limited‑liability entities because they can enforce security against company assets.
  • Decision‑making and control: Unlimited‑liability owners often retain full control, while limited‑liability firms may dilute control through share ownership.
  • Stakeholder confidence: Suppliers, customers and investors view limited liability as a sign of credibility and stability.
  • Entrepreneurial risk: The extent of personal exposure influences whether individuals are willing to start a business.

3. Forms of Business Ownership (Cambridge 1.2)

3.1 Sole Trader

  • Defining features: One individual owns and runs the business.
  • Legal status: Not a separate legal entity.
  • Liability: Unlimited.
  • Typical finance sources: Personal savings, bank overdraft, trade credit.
  • Examples: A local bakery, a freelance graphic designer.

3.2 General Partnership

  • Defining features: Two or more persons share ownership, profits and management.
  • Legal status: Not a separate legal entity (partners act as agents for the partnership).
  • Liability: Unlimited – each partner is jointly and severally liable for all debts.
  • Typical finance sources: Partners’ capital, bank loans, trade credit.
  • Examples: A law‑firm partnership, a small construction partnership.

3.3 Limited‑Liability Partnership (LLP)

  • Defining features: Partners enjoy limited liability while retaining partnership tax treatment.
  • Legal status: Separate legal entity.
  • Liability: Limited to the amount each partner has invested or guaranteed.
  • Typical finance sources: Partner contributions, bank loans, professional fees.
  • Examples: Accounting or architectural firms that wish to limit personal risk.

3.4 Private Limited Company (Ltd)

  • Defining features: Shares are held privately; the company cannot offer shares to the public.
  • Legal status: Separate legal entity.
  • Liability: Limited to the amount unpaid on shares.
  • Typical finance sources: Share capital, bank loans, retained earnings, debentures.
  • Examples: A family‑run manufacturing firm, a tech start‑up with private investors.

3.5 Public Limited Company (PLC)

  • Defining features: Can offer shares to the public and may be listed on a stock exchange.
  • Legal status: Separate legal entity.
  • Liability: Limited to the amount unpaid on shares.
  • Typical finance sources: Public share issues, corporate bonds, bank facilities.
  • Examples: Large retailers, multinational manufacturers.

3.6 Franchise

  • Defining features: A contractual relationship where the franchisor grants the right to use its brand, systems and support.
  • Legal status: Usually a sole trader or limited company operating under a franchise agreement.
  • Liability: Depends on the underlying legal form (often unlimited for a sole‑trader franchisee).
  • Typical finance sources: Franchise fee, personal savings, bank loans, sometimes franchisor financing.
  • Examples: Fast‑food outlets (e.g., McDonald’s), retail clothing chains.

3.7 Co‑operative (Co‑op)

  • Defining features: Owned and democratically controlled by members who use its services.
  • Legal status: Separate legal entity (often a limited company).
  • Liability: Usually limited – members’ liability limited to their share capital.
  • Typical finance sources: Member contributions, retained earnings, community loans.
  • Examples: Agricultural co‑ops, consumer co‑ops such as a local grocery co‑op.

3.8 Joint Venture

  • Defining features: Two or more separate businesses pool resources for a specific project or purpose.
  • Legal status: Can be a separate legal entity (commonly a limited company) or a purely contractual arrangement without a new entity.
  • Liability: If a limited company is formed, liability is limited; otherwise, partners may retain unlimited liability in proportion to the contractual terms.
  • Typical finance sources: Contributions from each partner, external investors, project‑specific loans.
  • Examples: A construction firm and an engineering firm building a bridge together.

3.9 Social Enterprise

  • Defining features: Pursues a primary social or environmental mission while operating commercially.
  • Legal status (UK examples):
    • Community Interest Company (CIC) – a special form of limited company with an asset‑lock.
    • Charitable company (company limited by guarantee with charitable status).
    • Private limited company (Ltd) or public limited company (PLC) that includes a “dual‑purpose” statement in its articles.
  • Liability: Determined by the chosen legal form (usually limited).
  • Typical finance sources: Grants, social‑impact investors, retained profits, community share offers.
  • Examples: A fair‑trade coffee retailer, a renewable‑energy co‑op.

4. Appropriateness of Ownership Types – When to Use Each Form

Ownership Form When It Is Most Suitable
Sole Trader Low‑capital start‑ups, businesses requiring quick decisions, professions where personal reputation is key (e.g., tradespeople, freelancers).
General Partnership Professional services where partners bring complementary skills and wish to share profits, and where the scale of finance needed is modest.
LLP Professional firms (accountants, architects, lawyers) that need limited liability but want partnership‑style tax treatment and flexible management.
Private Ltd (Ltd) Growing businesses that need to raise external capital, protect owners’ personal assets, and plan for succession or sale.
Public Ltd (PLC) Large enterprises that require substantial public finance, wish to list on a stock exchange, and can meet strict regulatory requirements.
Franchise Entrepreneurs who want to benefit from an established brand and support system while accepting limited operational freedom.
Co‑operative Member‑owned businesses where democratic control and profit‑sharing among users are core values (e.g., agricultural, retail co‑ops).
Joint Venture Two or more firms needing to combine resources for a single, time‑limited project or to enter a new market/technology together.
Social Enterprise Enterprises whose primary goal is social or environmental impact and that wish to attract mission‑aligned funding while limiting owners’ liability.
