Be prepared to compute the components of the Basic DuPont analysis for return on equity.
ROE = Profit Margin × Asset Turnover × Financial Leverage. Profit Margin = Net Income / Sales (measures profitability per dollar of sales);
Asset Turnover = Sales / Avg Total Assets (efficiency in using assets to generate sales); Financial Leverage = Avg Total Assets / Avg Equity
(extent of debt financing). This framework isolates operational performance from financing effects and helps analysts decompose differences in ROE across firms.
If you are presented with a balance sheet and income statement, identify line items as operating or nonoperating.
Operating assets include AR, Inventory, Prepaids, PP&E, ROU assets, Intangibles/Goodwill, Deferred tax assets, and Equity-method investments — all linked to core operations.
Operating liabilities include AP, Accrued expenses, Unearned revenue, Income taxes payable, Deferred tax liabilities, and pension obligations.
Nonoperating assets include cash, marketable securities, and long-term financial investments; nonoperating liabilities include interest-bearing debt and derivatives.
This classification separates business performance from financing effects for RNOA analysis.
Compute RNOA from the components identified in 1. above.
RNOA = NOPAT / Avg Net Operating Assets. NOPAT = Operating income × (1 − tax rate), isolating post-tax operating profit.
Net Operating Assets = Operating assets − Operating liabilities. This measure removes financing noise and captures true operational return.
Interpretation and calculation of DIO, DPO, DSO, Cash Conversion Cycle (CCC).
DIO = 365 × Avg Inventory / COGS (days inventory is held); DSO = 365 × Avg AR / Sales (days to collect cash); DPO = 365 × Avg AP / COGS (days to pay suppliers).
CCC = DIO + DSO − DPO. A shorter or negative CCC means faster cash recovery. For example, Apple’s CCC is negative because it collects cash upfront from customers.
Be prepared to calculate the ratios above and predict how average levels vary across industries.
Retail and manufacturing have high DIO and CCC due to inventory; SaaS firms have little DIO but moderate DSO; consulting firms have long DSO due to billing delays;
capital-intensive industries (utilities, energy) have longer CCC. These patterns reflect each industry’s working capital dynamics.
Provide an explanation for the inverse relationship between profit margin and asset turnover.
High-margin firms (e.g., Apple, Louis Vuitton) emphasize quality and differentiation, using more capital (lower turnover).
Low-margin firms (e.g., Walmart) compete on price and efficiency, operating with higher turnover and thinner margins.
What’s in Cost of Sales for these industries?
Manufacturing: Direct materials, direct labor, manufacturing overhead.
Retail: Purchase cost of goods for resale + freight-in.
Consulting: Labor, subcontractors, project costs.
SaaS: Cloud hosting, customer support, amortized software delivery costs.
Cost composition reflects each firm’s business model.
Why would stock buybacks inflate levels of return on equity?
Share repurchases reduce shareholders’ equity (denominator of ROE) without a proportional decrease in net income, artificially inflating ROE.
This makes performance appear stronger, so analysts adjust for equity changes over time.
What types of industries have higher receivables as a % of assets? Inventory? PPE? Deferred revenue?
Receivables: B2B, SaaS, consulting (customers pay later).
Inventory: Retail, manufacturing, and wholesale.
PPE: Energy, airlines, and utilities (capital-intensive).
Deferred revenue: SaaS and subscriptions (prepaid services). Each pattern reflects working capital needs.
What types of industries have high gross margins as a % of sales? R&D expense as a % of sales?
High gross margins: Software, biotech, luxury goods — product differentiation allows pricing power.
High R&D: Pharma, semiconductors, medtech, AI software — innovation-heavy sectors reinvest heavily in R&D.
Using the Advanced DuPont equation below, explain under what circumstances financial leverage boosts ROE above RNOA.
ROE = RNOA + FLEV × (RNOA − NNEP). Financial leverage increases ROE only when RNOA (operating return) > NNEP (after-tax cost of financing).
For instance, Pfizer’s 32% RNOA vs 4% debt cost raises ROE; if the spread is negative, leverage erodes shareholder value.
Explain areas for judgment/estimation analysts must watch under Rights of return.
Companies estimate returns and record refund liabilities, reducing net sales. Analysts watch whether actual returns align with estimates — e.g.,
Levi’s and Apple disclose return reserves, which affect revenue quality.
Gift cards.
Gift card sales are recorded as deferred revenue until redemption; unused balances (breakage) recognized as revenue over time based on historical redemption.
Chipotle’s gift card liability spikes in Q4 from holiday sales, then converts to revenue in Q1.
Variable consideration.
Includes rebates, service credits, and bonuses. Firms record expected value only if reversal risk is low.
Zoom’s SLAs create credits as variable consideration; changes affect period revenue.
Multiple element contracts.
Contracts with multiple deliverables (hardware, software, service) allocate transaction price by relative stand-alone selling prices.
Apple splits iPhone revenue among hardware, iCloud services, and updates, recognizing each over different timelines.
For performance obligations satisfied over time—Describe the cost-to-cost method.
Revenue recognized = (Costs incurred / Total expected costs) × Total contract value.
Used by construction and defense firms (e.g., Raytheon). Matches performance with revenue recognition over time.
What is the key source of estimation error for the cost-to-cost method? What happens later if earlier estimates were pessimistic?
The biggest uncertainty is total expected cost. If initial estimates were high (pessimistic), later periods recognize higher completion % and more revenue — a ‘catch-up’ gain.
What are typical types of contra revenue accounts?
Sales returns, rebates, discounts, and promotional allowances reduce gross to net sales.
Tracking changes in these accounts helps evaluate pricing pressure and revenue quality.
Name three ratios used in analyzing sales allowances.
1) Additions to Gross Sales / Gross Sales (income statement pressure).
2) Allowance balance / Gross Sales (adequacy).
3) Actual returns vs prior estimate (forecast accuracy).
Rising ratios may indicate more concessions or pricing stress.
Where would you locate bad debt expense in a company’s notes?
In the Accounts Receivable footnote or Summary of Significant Accounting Policies. Analysts examine the allowance rollforward to detect aggressive revenue recognition.
How would you adjust IS and BS if you believe a company underestimated the allowance for doubtful accounts?
Increase bad debt expense (reduces NI); increase allowance for doubtful accounts (contra-AR), lowering AR and retained earnings.
This correction yields a more conservative, realistic balance sheet.
For SEC reporters, where in a 10-K do you find revenue recognition policies and effects of estimate changes?
In Note 1 (Significant Accounting Policies) and MD&A’s Critical Accounting Estimates.
These explain how firms like Apple and Zoom allocate transaction prices and recognize revenue.
What are the two major categories of pro forma earnings reconciling items?
Recurring/core adjustments (e.g., stock comp) and nonrecurring/transitory items (e.g., restructuring, impairments).
Separating these clarifies earnings persistence.
Why would firms report pro forma earnings less than GAAP earnings?
To appear conservative and emphasize recurring performance, excluding temporary gains.
Helps rebuild investor trust after volatile quarters.
