• Compute the cash conversion cycle and explain its operational significance
• Analyze budget-to-actual variances and distinguish favorable from unfavorable results

The Core Idea: Ratios as Projections

A set of financial statements is a multi-dimensional object. The balance sheet has dozens of line items. The income statement has dozens more. The cash flow statement adds a third axis. No human can hold all of these dimensions in working memory simultaneously.

Financial ratios exist to solve this problem. Each ratio is a projection — it collapses the multi-dimensional financial position onto a single axis that answers one specific question. This is the same operation as taking a three-dimensional object and casting its shadow on a wall. The shadow is not the object. It loses information. But a well-chosen shadow reveals structure that would be invisible in the full 3D view.

The categories of ratios correspond to the angles from which you shine the light:

• Shine from the "can we pay our bills?" angle — the shadow is liquidity ratios
• Shine from the "are we making money?" angle — the shadow is profitability ratios
• Shine from the "can we survive long-term?" angle — the shadow is solvency ratios
• Shine from the "how efficiently do we use resources?" angle — the shadow is efficiency and performance metrics

No single projection tells the whole story. A company can look healthy from the profitability angle and critically ill from the liquidity angle — profitable but cash-starved. This kills businesses. The art of financial analysis is choosing the right projections for the question being asked.

Profitability Ratios

Profitability ratios measure how effectively an entity generates earnings relative to revenue, assets, or equity. They answer: is this entity creating wealth?

Gross Profit Margin

This is the most persistent earnings metric. Gross margin measures the percentage of revenue retained after direct costs — it reflects pricing power and production efficiency. A declining gross margin signals rising input costs, competitive pricing pressure, or a shift in product mix toward lower-margin items.

Return on Assets (ROA)

ROA measures how efficiently management uses assets to generate profit. Always use average total assets (beginning + ending / 2) unless the problem specifies otherwise. The average smooths out the effect of major asset acquisitions or disposals during the period.

Return on Equity (ROE) and DuPont Decomposition

ROE measures the return generated on shareholders' investment. By itself it is useful. Decomposed, it is revelatory. The DuPont identity breaks ROE into its three constituent drivers:

ROE = Net Profit Margin x Asset Turnover x Equity Multiplier

This is not three separate ratios that happen to multiply together. It is a decomposition of a single question — "what return are shareholders getting?" — into its three channels. Every change in ROE must come from one of these three:

1. The entity kept more of each revenue dollar (margin improvement)
2. The entity generated more revenue per dollar of assets (efficiency improvement)
3. The entity used more debt relative to equity (leverage increase)

The critical insight: leverage amplifies both returns and risk. A company can boost ROE by borrowing more, but this does not improve the underlying business — it just magnifies whatever profitability and efficiency already exist. If the underlying business deteriorates, leverage amplifies the losses just as readily.

Worked Example — DuPont Decomposition

Company A and Company B both report ROE of 15%. Identical headline number. But the decomposition reveals radically different businesses:

Company A earns a healthy margin with modest leverage. Company B earns a thin margin and compensates with heavy leverage. Same ROE, completely different risk profiles. In a downturn, Company A has margin to absorb losses. Company B has almost none — and its debt obligations remain fixed.

Liquidity Ratios

Liquidity ratios assess an entity's ability to meet short-term obligations. They answer: can this entity pay its bills?

Current Ratio

A ratio above 1.0 means current assets exceed current liabilities. But context matters — a very high current ratio may signal inefficient use of assets (excess cash sitting idle, slow-moving inventory). Industries with predictable cash flows (utilities) can operate comfortably at lower current ratios than industries with volatile revenues (construction).

Quick Ratio (Acid-Test)

The quick ratio strips out inventory and prepaid expenses — assets that may not convert to cash quickly. It is the more conservative liquidity measure. If a company has a healthy current ratio but a weak quick ratio, it may be sitting on slow-moving or obsolete inventory.

Accounts Receivable Turnover

Higher turnover means faster collection. Days sales outstanding (DSO = 365 / AR Turnover) converts the ratio to an average collection period in days. If DSO is climbing, the entity is taking longer to collect — a potential cash flow warning.

Inventory Turnover

Higher turnover means inventory sells through faster. Days inventory outstanding (DIO = 365 / Inventory Turnover) measures how long inventory sits before being sold. A declining turnover ratio may signal obsolescence, overproduction, or weakening demand.

Accounts Payable Turnover

Days payable outstanding (DPO = 365 / AP Turnover) measures how long the entity takes to pay suppliers. A longer DPO preserves cash but may strain supplier relationships or signal financial distress.

The Cash Conversion Cycle

The cash conversion cycle combines all three turnover metrics into a single measure of how long cash is tied up in operating activities:

CCC = DSO + DIO - DPO

A shorter CCC means cash circulates faster through the business. A negative CCC (rare but possible — e.g., Amazon) means the entity collects from customers before it pays suppliers.

Worked Example — Cash Conversion Cycle

Cash is tied up for about 91 days from the time inventory is purchased to the time customer payment is collected, net of the time the entity delays paying its own suppliers.

Solvency Ratios

Solvency ratios evaluate an entity's ability to meet long-term obligations and the structure of its capital. They answer: can this entity survive?

Debt-to-Equity Ratio

Higher values indicate greater financial leverage and risk. A debt-to-equity of 2.0 means the entity has twice as much debt as equity — creditors have provided more capital than shareholders.

Times Interest Earned (Interest Coverage)

This ratio measures how comfortably the entity can cover its interest payments from operating earnings. A ratio below 1.5 is a warning sign — the entity is barely generating enough to service its debt. A ratio below 1.0 means operating earnings do not cover interest, and the entity is burning reserves or borrowing to pay interest.

Performance Metrics

EBITDA

EBITDA strips out financing decisions (interest), tax structure (income tax expense), and non-cash charges (depreciation and amortization) to approximate operating cash flow. It is widely used in valuation and debt covenants.

Important: EBITDA is not a GAAP measure. The exam may test your understanding of its limitations — it ignores capital expenditure requirements, working capital changes, and the real cost of debt. A company can have strong EBITDA and still be cash-flow negative if it requires heavy capital investment.

Price-to-Earnings (P/E) Ratio

P/E measures how much investors are willing to pay per dollar of earnings. A high P/E may signal growth expectations (investors paying a premium for future earnings) or overvaluation. A low P/E may signal value or distress — context determines which.

Asset Turnover

Asset turnover measures revenue efficiency per dollar of assets. It is the middle component of the DuPont decomposition. Asset-light businesses (consulting firms, software companies) typically have high turnover. Asset-heavy businesses (manufacturing, utilities) have low turnover but may compensate with higher margins.

The Ratio Reference

Budget-to-Actual Variance Analysis

Variance analysis compares planned results to actual results and identifies the causes of deviation. This is a different type of projection — instead of comparing two companies, you are comparing the entity against its own expectations.

The Basic Formula

The sign convention depends on the line item:

• Revenue: Positive variance (actual > budget) is favorable
• Expenses: Negative variance (actual < budget) is favorable

Variance Decomposition

The most useful variance analysis decomposes the total variance into its components:

Price variance = (Actual Price - Standard Price) x Actual Quantity Volume variance = (Actual Quantity - Standard Quantity) x Standard Price

This decomposition matters because price and volume variances have different causes and different remedies. A materials price variance may reflect commodity market changes outside management's control. A labor efficiency variance may reflect training deficiencies that management can fix.

Worked Example — Variance Analysis

Budget: 10,000 units at $50 each = $500,000 revenue Actual: 9,500 units at $52 each = $494,000 revenue

The entity charged more per unit (favorable) but sold fewer units (unfavorable). The volume shortfall more than offset the pricing gain. This tells management the problem is demand, not pricing — a very different strategic response than if the total variance were driven by price erosion.

Key Exam Patterns

1. Always use averages for balance sheet items in ratio denominators unless the problem specifies otherwise
2. Know which ratio answers which question — the exam describes a scenario and asks you to select the appropriate ratio, not just compute one
3. Understand directional impact — given a transaction, which ratios improve and which deteriorate?
4. DuPont is the master decomposition — if the exam asks why ROE changed, decompose it into margin, turnover, and leverage
5. EBITDA is not GAAP — know its limitations (ignores capex, working capital, cost of debt)
6. Budget variances require context — a favorable expense variance from cutting maintenance may signal future problems, not current success
