Lesson Overview
Profitability does not guarantee survival. Even profitable companies can fail if they cannot meet short-term obligations or if debt becomes unmanageable.
This lesson focuses on liquidity (short-term financial safety) and leverage (long-term financial risk), using ratios that highlight cash availability, debt burden, and solvency.
Learning Objectives
- Calculate and interpret key liquidity ratios.
- Calculate and interpret leverage and coverage ratios.
- Understand the tradeoff between leverage and financial risk.
- Identify warning signs of liquidity stress or excessive leverage.
- Explain why cash flow matters more than accounting profit for solvency.
Liquidity: Short-Term Financial Safety
Liquidity ratios answer the question: Can the business meet its obligations over the next year?
Working Capital
- Working Capital = Current Assets − Current Liabilities
Positive working capital provides a buffer against short-term shocks. Negative working capital may indicate reliance on continuous cash inflows.
Current Ratio
- Current Ratio = Current Assets ÷ Current Liabilities
A ratio above 1.0 suggests the firm can cover short-term obligations, but excessively high values may indicate idle or inefficient assets.
Quick Ratio (Acid-Test)
- Quick Ratio = (Cash + Marketable Securities + A/R) ÷ Current Liabilities
The quick ratio removes inventory, focusing on assets that can be converted to cash quickly.
Cash-Based Liquidity Measures
Accounting liquidity can look strong even when cash is tight. Cash-based measures provide a more conservative view.
Operating Cash Flow Coverage
- Operating Cash Flow Coverage = Operating Cash Flow ÷ Current Liabilities
This ratio shows whether the company’s normal operations generate enough cash to cover short-term obligations.
Leverage: Long-Term Financial Risk
Leverage ratios measure how much a company relies on borrowed money and how exposed it is during downturns.
Debt-to-Equity Ratio
- Debt-to-Equity = Total Debt ÷ Shareholders’ Equity
Higher leverage can amplify returns—but also increases the risk of financial distress.
Debt-to-Assets Ratio
- Debt-to-Assets = Total Debt ÷ Total Assets
This ratio shows what proportion of the company’s assets are financed by debt.
Coverage Ratios: Can the Firm Service Its Debt?
Coverage ratios focus on the firm’s ability to make required payments.
Interest Coverage Ratio
- Interest Coverage = EBIT ÷ Interest Expense
A low interest coverage ratio signals vulnerability to earnings declines or rising interest rates.
Cash Interest Coverage
- Cash Interest Coverage = Operating Cash Flow ÷ Interest Paid
Cash-based coverage is often more reliable than earnings-based measures.
Liquidity vs. Leverage: The Tradeoff
- High leverage increases ROE during good times.
- High leverage magnifies losses during downturns.
- Strong liquidity provides flexibility and resilience.
Healthy firms balance growth, leverage, and liquidity rather than maximizing any single ratio.
Warning Signs to Watch For
- Declining current or quick ratios over time.
- Rising debt with flat or falling cash flow.
- Interest coverage approaching 1.0.
- Positive earnings but negative operating cash flow.
Practice: Check Your Understanding
- Why might a high current ratio still signal problems?
- Which is more dangerous: high leverage or weak liquidity?
- Why is operating cash flow important for solvency?
- How does leverage affect risk during economic downturns?

With Unit 1 complete, you now understand how financial statements work, how they connect, and how to analyze performance and risk using ratios.
In Lesson 1.8: Financial Ratios and Statement Analysis, we’ll put the three statements together and learn how ratios translate raw numbers into insight about profitability, liquidity, and risk.
