Absorption and Variable Costing

Liquidity and solvency analysis focuses on a company's ability to pay its bills in the short term and survive in the long term. Students learn to calculate the Current Ratio, Quick (Acid-Test) Ratio, and Gearing Ratio. In the context of Singapore's dynamic economy, where SMEs often face cash flow challenges, these concepts are highly practical. Students learn that a profitable company can still fail if it lacks the liquidity to meet its immediate obligations.

Simulation Game60 min · Small Groups

Simulation Game: The Cash Crunch

Students manage a virtual business where they must decide whether to take on more debt or sell assets to meet an upcoming loan repayment. They see the immediate impact on their gearing and liquidity ratios as they make choices.

Formal Debate30 min · Whole Class

Formal Debate: Is Debt Dangerous?

Divide the class into two sides: one arguing that high gearing is a useful tool for growth (leveraging), and the other arguing it is a dangerous risk to solvency. They must use ratio examples to support their positions.

Inquiry Circle45 min · Small Groups

Inquiry Circle: The Working Capital Race

Groups compare the working capital cycles of a retailer like NTUC FairPrice versus a property developer. They map out the time it takes to convert inventory to cash and discuss why the retailer can survive with a lower current ratio.

A few notes on teaching this unit


Watch Out for These Misconceptions

  • A current ratio of 2:1 is always the ideal target.

    The 'ideal' ratio varies by industry. A supermarket can operate with a much lower ratio because it has fast cash inflows, while a manufacturing firm needs more. Peer comparison of different industry data helps students move away from rigid 'rule of thumb' thinking.

  • Liquidity and solvency are the same thing.

    Liquidity is about short-term cash (paying bills today), while solvency is about long-term survival (total assets exceeding total liabilities). Using a timeline to plot different obligations helps students distinguish between these two time horizons.
