Accounting Interview Questions

Walk me through the three financial statements.

The three statements are the income statement, the balance sheet and the cash flow statement, and each answers a different question.

1. Income statement: revenue, expenses and profit over a period, on an accrual basis. It starts with revenue, subtracts cost of goods sold to reach gross profit, then operating expenses to reach operating income, then interest and taxes to reach net income. 2. Balance sheet: what the company owns (assets) and owes (liabilities), plus shareholders' equity, at a single date. Assets always equal liabilities plus equity. 3. Cash flow statement: starts with net income, adjusts for non-cash items such as depreciation and for changes in working capital to get cash flow from operations, then adds cash flow from investing (capex, acquisitions) and from financing (debt, equity, dividends) to arrive at the net change in cash.

The statements are linked: net income flows into retained earnings on the balance sheet and is the first line of the cash flow statement, and the net change in cash equals the change in the cash line between two balance sheets.

What is the difference between cash and accrual accounting, and why do companies use accrual?

Cash accounting records revenue when the customer pays and expenses when the bill is paid. Accrual accounting records revenue when it is earned and expenses when they are incurred, whatever the timing of the cash.

Say a company delivers a TV in December and the customer pays in January. Under cash accounting the sale appears in January; under accrual accounting it appears in December, with a receivable on the balance sheet until the cash arrives. Accrual accounting also defers cash received before delivery (deferred revenue) and spreads the cost of long-lived assets over their useful lives through depreciation instead of expensing them when paid.

Public companies report on the accrual basis because it matches revenue with the costs of earning it in the same period, so it shows how the business actually performed. Cash accounting is simpler, but it swings with the timing of payments: a big equipment purchase or a customer prepayment can make one quarter look far better or worse than it was.

The cost is that accrual profit and cash can diverge, which is why companies also report a cash flow statement: it starts from accrual net income and adjusts back to the cash actually received and paid.

Why does the balance sheet always balance?

Because of how equity is defined. Equity is the residual: whatever is left of the assets after deducting the liabilities. So assets equal liabilities plus equity by construction, at every date.

Another way to see it: everything a company owns was financed either by someone it owes (lenders, suppliers, employees) or by its owners, who invested money or left profits in the business. Every asset has a matching claim on the other side.

That is why every transaction must move the two sides by the same amount. It either swaps one asset for another (buying equipment with cash), raises both sides (borrowing, issuing shares), lowers both sides (repaying debt, paying a dividend), or swaps one claim for another (converting debt into shares). Profits and losses reach the balance sheet through retained earnings, so the income statement can never pull the two sides apart.

In a model, this makes the balance check a test: if a projected balance sheet doesn't balance, a flow has been missed or linked with the wrong sign, and the fix is to find it, never to plug the difference.

What are the revenue recognition and matching principles?

Together they decide which period revenue and costs land in, independently of when cash moves.

Revenue recognition: revenue is recorded when the company transfers control of the goods or services to the customer, in the amount it expects to receive. A retailer recognizes a sale when the customer takes the goods; a subscription is recognized over the period of service. A prepayment creates a liability (deferred revenue), not revenue, and a sale on credit creates revenue and a receivable on the day of delivery.

Matching: expenses are recorded in the same period as the revenue they help generate. The cost of goods sold is recognized when the goods are sold, the cost of a long-lived asset is spread over its useful life through depreciation, and costs with no clear link to future revenue, such as most marketing and overhead, are expensed as incurred.

Timing does not change the total profit a business earns over its life, only which period shows it. That still matters a lot for bankers, because multiples, covenants and earnouts are all measured on a specific period, so revenue pulled into a quarter or costs capitalized out of it raise the base a valuation is built on.

A company bought equipment for $100, has $60 of accumulated depreciation, and the equipment is now worth $500. What is on the balance sheet, and why?

The equipment is carried at $40: its historical cost of $100 less $60 of accumulated depreciation. The $500 market value doesn't appear anywhere.

Under US GAAP, property, plant and equipment is held at historical cost, depreciated over its useful life, and written down if it is impaired, but never written up when its value rises. The reasons are reliability and verifiability: cost is a fact backed by a transaction, while market values of operating assets are estimates that can be hard to verify and easy to manipulate.

Fair value does apply to some items: marketable securities, derivatives and assets acquired in a business combination (recorded at fair value on the acquisition date). IFRS also allows a revaluation model for PP&E, though few companies use it. That's why book value can understate what a company's assets are worth, and why the gap only shows up when the asset is sold (as a gain) or the company is acquired.

What are the main sections of a 10-K, and how does a 10-Q differ?

The 10-K is the annual report, organized into four parts:

1. Part I, the business: the description of the business and its segments (Item 1), risk factors (Item 1A), properties and legal proceedings. 2. Part II, the numbers: the market for the shares and buybacks (Item 5), management's discussion and analysis or MD&A (Item 7), market risk (Item 7A), the audited financial statements and notes (Item 8), and internal controls (Item 9A). 3. Part III, governance: directors, executive pay and ownership, usually incorporated from the proxy statement. 4. Part IV, exhibits: material contracts such as the credit agreement and bond indentures.

The 10-Q is the quarterly report for the first three quarters. Its financial statements are condensed and unaudited (only reviewed by the auditor), it has shorter notes and its own MD&A, and it is filed sooner: 40 or 45 days after quarter end, against 60 to 90 days for the 10-K. There is no fourth-quarter 10-Q, so Q4 figures are derived from the 10-K less the nine-month year-to-date numbers.

For a banker, Item 8 and its notes drive the model, MD&A explains the drivers, and the exhibits matter most in financing work, because the credit agreement defines the EBITDA used for covenants.

Last fiscal year's revenue was $400. First-half revenue is $220 this year vs $200 a year ago. What is LTM revenue?

LTM revenue is $420.

The last twelve months are the last full fiscal year, plus the current year-to-date period, minus the same period of the prior year:

$\text{LTM} = \text{Last fiscal year} + \text{Current YTD} - \text{Prior-year YTD}$

So $400 + $220 - $200 = $420. The window now runs from the start of the second half of last year to the end of this year's first half: the stronger first half has replaced the weaker one.

The same formula works for any flow figure (EBITDA, net income, capex, operating cash flow), but never for balance sheet items such as debt or cash, which are taken from the latest balance sheet. Any one-time item has to be removed from every piece of the calculation that contains it, or it is removed twice.

Which differences between US GAAP and IFRS matter most when you compare companies?

The ones that move EBITDA, debt and operating cash flow, because those drive multiples and leverage:

1. Leases: under US GAAP an operating lease produces a single rent-like expense above EBITDA. Under IFRS 16 almost every lease is split into depreciation and interest, both below EBITDA, so an IFRS company's EBITDA and operating cash flow are higher and its debt includes lease liabilities. This is the largest difference for retailers, airlines and other lease-heavy businesses. 2. Development costs: US GAAP expenses most R&D, while IFRS capitalizes development costs once strict criteria are met, which lifts EBITDA for R&D-heavy companies. 3. Inventory: LIFO is prohibited under IFRS, and IFRS lets inventory write-downs reverse. 4. Cash flow classification: US GAAP puts interest paid in operating activities; IFRS has allowed a choice, and IFRS 18 moves interest paid to financing for most companies from 2027. 5. Balance sheet items: IFRS allows revaluing PP&E and reversing impairments (except on goodwill), recognizes provisions earlier, splits convertible debt into a liability and an equity piece, and lets the buyer measure noncontrolling interest at its share of net assets, which lowers goodwill.

In practice, a banker comparing an IFRS company with US peers moves lease costs back into EBITDA (or adds lease liabilities to everyone's debt), reverses capitalized development costs and checks where interest sits in the cash flow statement before comparing multiples or cash conversion.

Walk me through the income statement.

The income statement shows a company's revenue, expenses and profit over a period, on an accrual basis. It works down in layers:

1. Revenue: sales of goods and services recognized in the period, net of returns and discounts. 2. Cost of goods sold: the direct cost of what was sold. Revenue less COGS gives gross profit, which reflects pricing power and production efficiency. 3. Operating expenses: SG&A and R&D. Gross profit less operating expenses gives operating income, the profit of the core business before financing and tax. Depreciation and stock-based compensation are often allocated into these lines rather than shown separately. 4. Non-operating items: interest expense (net of interest income) and other income and expense, such as gains on investments, give pre-tax income. 5. Income tax provision: current plus deferred tax, which leaves income from continuing operations; results of discontinued operations are added net of tax to reach net income.

Below net income, the share belonging to minority holders of consolidated subsidiaries is deducted, and what is left for common shareholders, divided by the weighted-average share count, gives earnings per share. Bankers focus on the upper layers, gross profit, operating income and EBITDA, because they describe the business independently of how it is financed.

Revenue rises by $40 and COGS by $20, all in cash, 25% tax. Walk me through the three statements.

Net income rises by $15, and so do cash and retained earnings.

1. Income statement: revenue up $40 and COGS up $20, so gross profit and pre-tax income rise by $20. Tax at 25% is $5, so net income rises by $15. 2. Cash flow statement: net income is up $15. Everything was paid in cash, so there are no non-cash items or working capital changes to adjust for, and cash from operations, and cash overall, rise by $15. 3. Balance sheet: cash is up $15 on the assets side; retained earnings are up $15 on the equity side. Both sides rise by $15, so it balances.

If the sale had been on credit or the goods had come out of existing inventory, the profit would be the same but the cash would differ, through accounts receivable or inventory in the working capital section.

What is the difference between COGS and operating expenses, and why does it matter for gross margin?

COGS is the direct cost of the goods or services sold in the period: for a manufacturer, materials, production labor and factory overhead, including the depreciation of production equipment; for a service or software company, the cost of delivering the service, such as hosting or support staff. Operating expenses are the costs of running the business that are not tied to a specific sale: SG&A (sales, marketing, head office) and R&D.

The split matters because revenue less COGS is gross profit, and gross margin is the cleanest read on a product's economics: pricing power, sourcing and production efficiency, and product mix. COGS tends to move with volume, while many operating expenses are fixed, so a high gross margin also means more operating leverage.

The catch is that there is no single rule for what goes into COGS. One company puts shipping, depreciation or customer support in COGS and another puts them in SG&A, so two businesses with the same economics can report different gross margins. Before comparing gross margins across companies, a banker checks what each one includes.

Where does depreciation appear on the income statement, and how do you find total D&A when it is not a separate line?

Depreciation usually follows the function of the asset it relates to, because most companies present expenses by function. Depreciation of factory equipment goes into cost of goods sold (through inventory), depreciation of stores, offices and head-office systems goes into SG&A, and data center depreciation sits in cost of revenue. Some companies show a separate D&A line, but it often captures only part of the total.

To get the full figure:

- Cash flow statement: the D&A add-back in operating activities is the usual starting point, but it can include other items such as amortization of debt issuance costs, so check the label. - Segment note: often gives total D&A by segment, whatever line it was charged to. - PP&E and intangibles notes: give depreciation and amortization expense separately.

The safe approach is to take the cash flow figure and reconcile it to the notes before adding it to operating income to build EBITDA. Using only the income statement line understates EBITDA, and the error carries straight into the valuation.

Why can D&A on the cash flow statement differ from D&A on the income statement?

Mostly because the income statement often shows only part of D&A. When depreciation of production assets is charged to cost of goods sold, or other depreciation to SG&A, the separate D&A line covers only what is left, while the cash flow statement adds back the total non-cash charge.

The cash flow add-back can also be broader than D&A itself: it may include amortization of debt issuance costs or capitalized contract costs, depreciation of discontinued operations, or D&A of businesses acquired during the year.

So when building EBITDA, a banker takes the cash flow figure, reconciles it to the segment and asset notes, and strips out anything that is not depreciation or amortization of operating assets. Adding back non-operating amortization, such as debt costs that already sit in interest expense, would overstate EBITDA.

What is EBITDA, and why do bankers use it?

EBITDA is earnings before interest, taxes, depreciation and amortization: net income with interest, taxes and D&A added back, or operating income plus D&A. It approximates the profit of the core business before financing, tax and the accounting allocation of past capital spending.

Bankers use it because it is:

- Capital-structure neutral: it is measured before interest, so companies with different amounts of debt can be compared, and it pairs with enterprise value, which belongs to all capital providers. - Tax neutral: differences in tax jurisdictions and planning don't distort comparisons. - Independent of depreciation policy: it excludes D&A, which depends on useful-life estimates and on the prices paid in past acquisitions. - A first proxy for operating cash generation: which is why lenders size debt as a multiple of EBITDA and why EV/EBITDA is the most common valuation multiple.

Its limits matter as much: it ignores capex, working capital needs and taxes, so it is not cash flow. A capital-intensive company can have a large EBITDA and little free cash flow, which is why EBITDA multiples are compared within an industry and alongside EBITDA less capex.

Net income is $60, taxes $20, interest $10 and D&A $30. What are EBIT and EBITDA?

EBIT is $90 and EBITDA is $120.

Work up from net income: $60 of net income plus $20 of taxes gives $80 of pre-tax income; adding back $10 of interest gives EBIT of $90; adding back $30 of D&A gives EBITDA of $120.

In practice, a banker would also check for non-operating items between operating income and pre-tax income, such as investment gains or equity method income, and remove them so that EBIT and EBITDA describe only the core business.

When is EBIT more useful than EBITDA, and vice versa?

EBITDA is more useful when comparing companies with different depreciation policies, acquisition histories or asset ages, and as a rough measure of operating cash generation for debt sizing. It is the standard for leverage multiples and for EV/EBITDA in most industries, especially where companies have similar capital intensity.

EBIT is more useful when capital spending is a real, recurring cost of the business. Depreciation approximates the cost of replacing assets, so for capital-intensive companies (manufacturers, telecom, airlines) EBIT is closer to sustainable profit, and EV/EBIT avoids flattering a company that needs heavy reinvestment just to stand still. EBIT is also the base for operating taxes in an unlevered free cash flow and for return on invested capital.

A practical rule: if two companies have very different capex as a share of revenue, compare them on EBIT (or EBITDA less capex) as well as EBITDA; if their capex profiles are similar, EBITDA is fine and more widely available.

What kind of company would have the same EBITDA and net income?

One with no interest, no income tax and no depreciation or amortization, since those are the only items between the two.

A realistic example is a debt-free, asset-light pass-through entity, such as a consulting firm set up as a partnership or S corporation. It has no debt, so no interest; its profits are taxed at the owners' level, so no corporate income tax; and it owns almost no fixed assets, so D&A is close to zero.

The two figures can also match by coincidence when items offset, for example interest income exactly covering taxes and D&A.

What sits between operating income and pre-tax income, and why keep it out of operating income?

The non-operating items:

- Interest expense: coupons and loan interest, amortization of debt discounts and fees, commitment fees and finance lease interest. - Interest income on cash and investments, often netted against interest expense. - Other income and expense: gains and losses on investments, equity method income (when shown below operating income), foreign exchange gains and losses, gains or losses on retiring debt, fair value changes on derivatives not hedge-accounted, and the non-service components of pension cost.

They are kept out of operating income because they reflect financing choices, investment results and one-off events, not the performance of the core business. Two companies running identical businesses can have very different interest costs and investment gains depending on how they are funded and what they hold. Separating them lets operating income and EBITDA be compared across companies and paired with enterprise value, while interest and the other items are dealt with through net debt and the valuation bridge.

A company has 100 shares at $20 and 10 options with a $10 strike. How many diluted shares under the treasury stock method?

Diluted shares are 105.

The treasury stock method assumes the options are exercised and the cash received is used to buy back shares at the share price (for EPS, the average price over the period):

1. Exercise brings in 10 x $10 = $100 and creates 10 new shares. 2. $100 buys back $100 / $20 = 5 shares. 3. Net new shares: 10 - 5 = 5, so diluted shares are 100 + 5 = 105.

Only in-the-money options count. If the strike were above the share price, exercising them would create fewer shares than the proceeds could buy back, so they would be anti-dilutive and excluded.

Net income is $100 and there are 100 shares at $10. The company borrows $200 at 8% (25% tax) to buy back 20 shares. What happens to EPS?

EPS rises from $1.00 to $1.10, so the buyback is accretive.

1. New net income: interest is 8% x $200 = $16 before tax, or $12 after the 25% tax shield. Net income falls from $100 to $88. 2. New share count: $200 buys 20 shares at $10, leaving 80. 3. New EPS: $88 / 80 = $1.10.

The quick test is to compare two yields. The company's earnings yield is EPS over price, $1 / $10 = 10%, which is what each share bought back "costs" in lost earnings. The after-tax cost of debt is 8% x (1 - 25%) = 6%. Because 6% is below 10%, the buyback raises EPS. If the after-tax cost of funding were above the earnings yield (a high P/E stock, or expensive debt), the same buyback would be dilutive.

What is other comprehensive income, and what goes into it?

Other comprehensive income (OCI) holds certain gains and losses that change equity but are kept out of net income, usually because they are unrealized and can reverse. Net income plus OCI equals comprehensive income, and the running total sits in equity as accumulated other comprehensive income (AOCI).

The main items under US GAAP:

- Foreign currency translation adjustments from translating foreign subsidiaries into the reporting currency. - Cash flow hedges: gains and losses on derivatives hedging future cash flows, held until the hedged transaction hits earnings. - Available-for-sale debt securities: unrealized gains and losses. - Pensions: actuarial gains and losses and prior service cost not yet recognized in pension expense.

Most of it is temporary: when the item is realized (a foreign subsidiary is sold, a hedged purchase happens, a security is sold), the accumulated amount is recycled into net income.

It matters to bankers for banks, insurers and companies with big foreign operations or pensions, where AOCI can move book value and return on equity materially, for example when rising rates create unrealized losses on a bank's bond portfolio.

Walk me through the balance sheet.

The balance sheet shows what a company owns and owes at a single date, and it always balances: assets equal liabilities plus shareholders' equity. Both sides are split between current items (turning into cash or due within a year) and noncurrent items.

1. Current assets: cash and equivalents, short-term investments, accounts receivable, inventory and prepaid expenses. 2. Noncurrent assets: PP&E net of accumulated depreciation, right-of-use assets from leases, long-term investments, goodwill and other intangibles from acquisitions, and deferred tax assets. 3. Current liabilities: accounts payable, accrued expenses, deferred revenue, the current portion of debt and lease liabilities. 4. Noncurrent liabilities: long-term debt, long-term lease liabilities, deferred tax liabilities and pension obligations. 5. Shareholders' equity: common stock and additional paid-in capital, retained earnings, treasury stock and accumulated other comprehensive income, plus any noncontrolling interest.

Bankers read it for working capital (operating current assets less operating current liabilities), net debt for the bridge between enterprise and equity value, and capital intensity. Most items sit at historical cost, so book equity is not what the company is worth.

What is restricted cash, and how do you treat it in analysis?

Restricted cash is cash the company can't use freely for its operations: held in escrow, pledged as collateral, set aside under a loan agreement or for a legal settlement, or required as a deposit by a regulator. US GAAP requires it to be shown separately (or disclosed), and the cash flow statement reconciles cash, cash equivalents and restricted cash together.

In analysis, the question is what the cash can actually do. In the bridge from enterprise value to equity value, cash is subtracted from debt, so every dollar counted as available cash adds a dollar to equity value. Bankers therefore exclude restricted cash from net debt calculations, and often also adjust for:

- Trapped cash held abroad that can only be brought home with tax or regulatory cost. - Customer deposits or cash held on others' behalf. - Minimum operating cash the business needs to function.

In a sale, these become negotiation points: buyers argue such amounts shouldn't be paid for as excess cash.

A company raises its allowance for doubtful accounts by $20 (25% tax; bad debts are deductible only when written off). Walk me through the three statements.

Net income falls by $15, cash doesn't change, and net receivables fall by $20.

1. Income statement: $20 of credit loss (bad debt) expense, usually in SG&A, so pre-tax income falls by $20. The expense isn't deductible yet, so current tax is unchanged, but the company records a $5 deferred tax benefit for the future deduction. Net income falls by $15. 2. Cash flow statement: start with net income down $15, add back the $20 non-cash credit loss expense, and subtract the $5 deferred tax benefit (an increase in deferred tax assets). Cash from operations, and cash, are unchanged. 3. Balance sheet: net receivables fall by $20 (the allowance grows), deferred tax assets rise by $5, so assets fall by $15; retained earnings fall by $15. It balances.

When a specific receivable is later written off, the receivable and the allowance fall together with no income statement effect, and that is when the tax deduction arrives and the deferred tax asset reverses.

Sales grew 5% but receivables grew 10%. Is that a problem, and when could it be fine?

It deserves questions, but it isn't automatically a problem. Receivables growing faster than sales means customers are taking longer to pay, so DSO is rising and the business is tying up more cash per dollar of sales.

The worrying explanations:

- Looser credit terms to win sales, which pulls revenue forward at the cost of cash. - Customers in difficulty, so collections slow and future write-offs rise. - Aggressive revenue recognition, such as shipping ahead of demand at period end or booking revenue before it is earned.

The benign ones:

- Timing: a large sale late in the period, or a period end that falls before a big collection date, inflates the closing balance without changing collection behavior. - Mix shift: growth with customers who are good credits but have longer standard terms, such as large corporates or governments. - A deliberate, priced decision: extending terms to a strong customer in exchange for volume or price.

To tell them apart, a banker looks at monthly rather than quarter-end figures, the aging of receivables, the allowance relative to past-due balances, customer concentration, and whether operating cash flow is keeping up with earnings.

A company prepays $240 for a year of rent. Walk me through the statements at payment and after three months (25% tax, taxes follow book).

At payment, cash is simply swapped for a prepaid expense asset; over the next three months, $60 of it is expensed.

At payment:

1. Income statement: no effect, because no rent has been used yet. 2. Cash flow statement: the $240 increase in prepaid expenses is a use of cash in operating activities, so cash falls by $240. 3. Balance sheet: cash down $240, prepaid expenses up $240. Total assets don't change.

After three months:

1. Income statement: three months of rent, $60, is expensed. Pre-tax income falls by $60, tax by $15, and net income by $45. 2. Cash flow statement: net income down $45, plus the $60 decrease in prepaid expenses (a source of cash, because the expense was paid earlier), so cash from operations rises by $15, the tax saved. 3. Balance sheet: prepaid expenses down $60, cash up $15, so assets fall by $45; retained earnings fall by $45. It balances.

The remaining $180 of prepaid rent is expensed over the next nine months.

What are the main components of shareholders' equity?

Equity splits into what owners put in, what the company kept, and a few adjustments:

- Common stock and additional paid-in capital (APIC): the amount shareholders paid for their shares (par value in common stock, the rest in APIC), plus the value of stock-based compensation. - Retained earnings: cumulative net income since inception, less cumulative dividends; an accumulated deficit if losses exceed profits. - Treasury stock: a deduction for shares the company has bought back and holds, usually at cost. - Accumulated other comprehensive income (AOCI): cumulative gains and losses kept out of net income, such as currency translation and unrealized gains on certain securities. - Preferred stock classified as equity, if any, and noncontrolling interests: the share of consolidated subsidiaries owned by outside shareholders.

None of these accounts is cash. Equity is the residual of assets minus liabilities, measured mostly at historical cost.

Can shareholders' equity be negative, and what does it tell you?

Yes. Equity is just assets minus liabilities, so it turns negative whenever liabilities exceed assets on the books. What it means depends on how it got there.

Losses: an accumulated deficit large enough to wipe out the capital invested, typical of struggling companies or early-stage businesses that have burned through funding. Here it is a warning sign about solvency.

Capital returns: a profitable company that has paid out more in buybacks and dividends than it has earned and raised over its life, often funded with debt. Many mature consumer, restaurant and retail businesses with stable cash flows look like this and remain highly creditworthy.

In the second case negative equity says little about value: assets sit at historical cost, and brands, franchise systems and other internally built value aren't recorded at all. Lenders and investors in those companies focus on cash flow, EBITDA and leverage instead. The practical consequences are that return on equity becomes meaningless and book-value-based ratios can't be used.

What does the statement of shareholders' equity show, and why do bankers look at it?

It reconciles each equity account from the start of the period to the end: net income added to retained earnings, dividends deducted, shares issued (including for stock-based compensation), shares repurchased, other comprehensive income, and other direct adjustments such as the effect of adopting a new accounting standard. It usually also rolls forward the share count.

Bankers use it to see quickly:

- Payout: dividends and buybacks relative to net income, which shows whether the company returns more than it earns. - Net dilution: shares issued to employees against shares bought back, which shows whether buybacks actually reduce the share count. - Equity moving outside net income: currency translation, pension remeasurements or purchases of minority stakes change equity without touching the income statement. - Consistency: net income, dividends and buybacks should tie to the income statement and the cash flow statement.

What is the difference between shareholders' equity and equity value, and why can they be so far apart?

Shareholders' equity (book value) is an accounting residual: assets minus liabilities on the balance sheet. Equity value (market capitalization for a public company) is what investors pay for the shares: share price times diluted shares outstanding, reflecting expected future cash flows.

They diverge for several reasons:

- Historical cost: PP&E, inventory and acquired intangibles stay at what was paid, less depreciation and write-downs, and aren't written up when they gain value. - Unrecorded intangibles: brands, technology and customer relationships built internally are expensed, so they never appear as assets. - Buybacks: repurchases at prices far above book value cut book equity by the full price paid. - Expectations: market value prices in future growth and returns, which no balance sheet records.

So a highly valued company can have small or even negative book equity. Book value matters more where assets are financial and marked close to fair value, such as banks and insurers, which is why they are valued on price-to-book.

Company A has $100 of assets and Company B has $200. Which is worth more?

You can't tell from assets alone. A company is worth the present value of the cash flows it will generate, not the book value of what it owns.

Two reasons the asset figures don't answer the question:

Liabilities: what belongs to shareholders is assets minus liabilities. If B has $190 of debt and A has none, A's equity is larger even on a book basis.

What the assets earn: assets sit at historical cost and many valuable ones aren't recorded at all. A software company with $100 of book assets and strong recurring cash flows can be worth far more than an asset-heavy manufacturer with $200 of aging equipment and thin margins.

To compare them, I'd want each company's cash flows, growth, margins and debt, and then value them on multiples of earnings or a DCF.

Walk me through the cash flow statement.

The cash flow statement explains the change in cash between two balance sheets, in three sections:

1. Operating activities: start with net income, add back non-cash charges such as depreciation, amortization, stock-based compensation and deferred taxes, remove non-operating gains and losses, and adjust for changes in working capital (receivables, inventory, payables, deferred revenue). The result is cash flow from operations. 2. Investing activities: capital expenditures, acquisitions, proceeds from selling assets or businesses, and purchases and sales of investments. 3. Financing activities: debt raised and repaid, shares issued and repurchased, and dividends paid.

The three sections add up to the net change in cash, which, together with any exchange-rate effect, equals the change in cash (including restricted cash) on the balance sheet.

Bankers use it for cash conversion (operating cash flow against net income or EBITDA), capital intensity (capex against revenue and depreciation), free cash flow, and how dividends and buybacks are funded.

Why does a company need a cash flow statement if it already has an income statement?

Because the income statement measures profit on an accrual basis, not cash. Revenue is recorded when earned even if the customer hasn't paid, expenses when incurred even if unpaid, and the cost of equipment is spread over years through depreciation. None of that tells you how much cash the business actually produced or used.

The cash flow statement fills that gap. It shows:

- Whether earnings turn into cash: working capital growth, such as rising receivables and inventory, can absorb the cash from a profitable year. - Cash spending that never hits the income statement directly: capex, acquisitions, debt repayments, buybacks and dividends. - How the company is funded: whether it pays its way from operations or relies on borrowing and equity raises.

That's why a company can be profitable and still run out of cash, and why lenders and buyers focus on free cash flow rather than net income alone.

Why does the cash flow statement start with net income rather than operating income?

Because under US GAAP, cash flow from operations includes interest paid and taxes paid, and net income is the figure that already reflects both. Starting from operating income would leave out two of the largest operating cash outflows.

Starting from net income also makes the statement a clean bridge from the bottom of the income statement to cash. The indirect method then:

1. Adds back non-cash charges such as depreciation, amortization, stock-based compensation and deferred taxes. 2. Removes gains and losses that belong elsewhere, such as a gain on selling equipment, whose cash shows up in investing. 3. Adjusts for changes in working capital.

It also ties the statements together: the same net income that starts the cash flow statement flows into retained earnings on the balance sheet. And whatever format a company uses, US GAAP requires a reconciliation from net income to operating cash flow.

If depreciation is a non-cash expense, why does it affect cash?

Because it is tax deductible. Depreciation itself uses no cash; the cash left when the asset was bought, and that outflow sat in investing activities at the time. But depreciation reduces pre-tax income, and lower taxable income means lower taxes paid.

With a 25% tax rate, $10 of extra depreciation lowers pre-tax income by $10 and net income by $7.50. On the cash flow statement, the $10 is added back because it used no cash, so operating cash flow ends up $2.50 higher: exactly the tax saved, the depreciation tax shield.

That's why depreciation is added back in the operating section: net income was reduced by an expense that didn't use cash in the period. The only real cash effect is through taxes (in practice through tax depreciation, which can differ from book depreciation, with the gap captured in deferred taxes).

Why does an increase in an operating asset reduce cash flow, and an increase in an operating liability raise it?

Because net income records revenue and expenses when earned or incurred, not when cash moves, and the working capital accounts hold the difference.

Operating asset up = cash tied up. An increase in receivables means revenue was recorded but not yet collected; an increase in inventory means cash was spent on stock not yet sold; an increase in prepaid expenses means cash was paid before the expense was recorded. In each case cash is lower than net income suggests, so the increase is subtracted.

Operating liability up = cash kept. An increase in payables or accrued expenses means costs were recorded but not yet paid; an increase in deferred revenue means customers paid before the revenue was earned. Cash is higher than net income suggests, so the increase is added.

Decreases work the other way: collecting receivables or running down inventory releases cash, and paying down payables uses it. A quick check is the balance sheet itself: if an asset other than cash goes up, something else must change to keep it balanced, and with liabilities and equity unchanged, that is cash going down.

Free cash flow is growing, but the change in working capital is more negative every year. What could that mean?

It means the business is putting more cash into working capital each year, yet profits are growing fast enough that free cash flow still rises. Whether that is fine depends on why working capital is absorbing cash.

Healthy growth: if revenue is growing quickly and days (DSO, DIO, DPO) are stable, working capital simply grows with sales. Growth is a use of cash for most businesses, so a larger outflow each year is expected.

Deteriorating efficiency: if days are rising, the company is collecting more slowly, building inventory or paying suppliers faster, so it needs more cash per dollar of sales. That can signal weakening customers, looser credit terms to win sales, inventory that isn't selling, or revenue recognized ahead of real demand.

Either way, it is worth noting that free cash flow is growing more slowly than earnings, so cash conversion is falling. A banker would look at the days metrics over several years and compare working capital growth with revenue growth before forecasting it to continue.

What are the main items in cash flow from investing activities?

Investing activities cover cash spent on, or received from, long-term assets and investments:

- Capital expenditure: purchases of property, plant and equipment, and often capitalized software. - Acquisitions: cash paid for businesses, net of the cash they held. - Disposals: proceeds from selling property, equipment, businesses or investments (the full proceeds, with any gain or loss removed from operating cash flow). - Securities and investments: purchases, sales and maturities of marketable securities and other investments. - Loans made and collected, for non-financial companies.

For analysis, the key line is capex, ideally split between maintenance (keeping existing capacity running) and growth (adding capacity), since free cash flow and capital intensity depend on it. Large acquisition outflows show how much growth is bought rather than built, and securities purchases and sales can swing the section without saying anything about the business.

What is the difference between the direct and indirect methods?

They are two ways of presenting the operating section; the operating cash flow total, and the investing and financing sections, are identical under both.

Direct method: lists the gross operating cash flows by type: cash received from customers, cash paid to suppliers and employees, interest and taxes paid.

Indirect method: starts from net income and adjusts it for non-cash items, gains and losses that belong in investing or financing, and changes in working capital.

US GAAP encourages the direct method, but almost every company uses the indirect one: accounting systems record accruals rather than cash by category, a reconciliation from net income has to be disclosed anyway, and analysts' models are built around it. The indirect format is also more useful for analysis, because it shows exactly why cash differs from earnings: which non-cash charges and which working capital movements drove the gap.

Where do interest paid, interest received, dividends paid and dividends received go on the cash flow statement under US GAAP, and what changes under IFRS?

Under US GAAP the rule follows the income statement: anything that runs through net income is operating.

- Interest paid: operating, because interest expense is part of net income (interest capitalized into an asset under construction goes to investing). - Interest received: operating. - Dividends received: generally operating, as a return on an investment. - Dividends paid: financing, because they are a distribution to owners, not an expense. - Taxes paid: operating, even taxes on a gain from selling an asset.

Under IFRS (IAS 7) these have been policy choices: interest and dividends paid can be operating or financing, and interest and dividends received operating or investing. An IFRS company that puts interest paid in financing shows higher operating cash flow than an identical US company. From 2027, IFRS 18 removes most of the choice for companies without specified main business activities: interest and dividends paid go to financing, and interest and dividends received to investing.

So before comparing operating cash flow or cash conversion across frameworks, a banker checks each company's policy and moves interest to the same place.

EBITDA is $200, D&A $40, tax 25%, capex $50, and working capital rises by $10. What is unlevered free cash flow?

Unlevered free cash flow is $100.

$\text{UFCF} = \text{EBIT} \times (1 - t) + \text{D\&A} - \text{Capex} - \Delta\text{NWC}$

1. EBIT: $200 - $40 of D&A = $160. 2. Taxes on EBIT: 25% x $160 = $40, leaving $120 (taxes are calculated as if the company had no debt, so there is no interest tax shield). 3. Add back D&A: $120 + $40 = $160. 4. Subtract capex and the working capital increase: $160 - $50 - $10 = $100.

This is the cash available to all capital providers, debt and equity, before any interest is paid, which is why it is discounted at WACC to give enterprise value.

What is the difference between levered and unlevered free cash flow?

The difference is the treatment of debt.

Unlevered free cash flow is the cash generated by the business before any payments to lenders: EBIT after tax (with taxes calculated as if there were no debt), plus D&A, less capex and the increase in working capital. It belongs to all capital providers, so it is discounted at WACC and gives enterprise value.

Levered free cash flow is what's left after interest (net of its tax shield), and in some definitions after mandatory debt repayments too. Operating cash flow less capex under US GAAP is already levered, because interest paid sits in operating activities. It belongs to shareholders, so it pairs with the cost of equity and equity value.

Unlevered free cash flow is the standard for DCFs because it is independent of capital structure. Levered free cash flow is what leveraged finance bankers and private equity investors watch, because it shows how fast a business can pay down the debt used to buy it.

Why isn't EBITDA a good proxy for cash flow?

Because EBITDA leaves out several things that consume real cash:

- Capex: EBITDA excludes depreciation, but not the need to replace and add assets. For a capital-intensive company, EBITDA can be large while EBITDA less capex is small. - Working capital: growth in receivables and inventory absorbs cash that EBITDA ignores. - Interest and taxes: both are paid in cash and both sit below EBITDA. - Stock-based compensation: usually added back in adjusted EBITDA, though it is a real cost borne through dilution or buybacks. - Items excluded as "one-time": restructuring, litigation and similar charges still require cash, and in some companies they recur.

EBITDA is useful as a capital-structure-neutral earnings measure, and for many businesses it is a reasonable first proxy for operating cash generation. But a company's ability to service debt or pay dividends depends on free cash flow, so bankers look at EBITDA less capex, cash conversion and free cash flow alongside it.

How can a company with positive net income or EBITDA run out of cash and go bankrupt?

Because profit and EBITDA aren't cash, and companies fail when they can't pay what they owe, not when their earnings are low. The main gaps:

- Working capital growth: receivables and inventory grow with sales, so a fast-growing company can spend its cash on stock and wait months to collect, while reporting rising profits. - Capex ahead of revenue: factories, stores or data centers are paid for upfront but reach the income statement only gradually through depreciation, which EBITDA ignores altogether. - Interest and debt principal: EBITDA is before interest, and principal repayments never appear on the income statement at all. A profitable company with a large maturity it can't refinance can still default. - Profit recognized before cash is certain: aggressive revenue recognition, estimates on long-term contracts or unrealized gains produce earnings that may never arrive as cash. - Items outside EBITDA: large one-time charges such as litigation, restructuring or taxes still require cash.

That's why lenders and buyers watch cash conversion, working capital days, liquidity (cash plus undrawn credit lines) and the debt maturity schedule, not just earnings. The reverse also happens: a company with a net loss can generate positive operating cash flow, thanks to large non-cash charges or customers who prepay.

Revenue of $365 grows 20% and DSO stays at 45 days. How much cash does the growth tie up in receivables?

About $9.

1. Receivables before: revenue of $365 is $1 a day, so 45 days of sales is $45 of receivables. 2. Receivables after: revenue grows 20% to $438, or $1.20 a day, so 45 days is $54. 3. Cash tied up: receivables rise by $9, which is subtracted in operating cash flow even though the company is collecting just as fast as before.

The point is that growth itself is a use of cash: with unchanged payment terms, receivables grow in line with sales. The same logic applies to inventory, partly offset by payables, which is why fast-growing companies with long cash conversion cycles can report record profits and shrinking cash.

How do the three financial statements link together?

Through a small number of flows, starting with net income:

1. Net income is the bottom line of the income statement. It is the first line of the cash flow statement and, less dividends, flows into retained earnings on the balance sheet. 2. Non-cash charges such as depreciation and amortization, stock-based compensation and deferred taxes are added back on the cash flow statement, and each one changes a balance sheet line: D&A reduces PP&E and intangibles, SBC increases paid-in capital, deferred taxes change deferred tax balances. 3. Working capital: changes in receivables, inventory, payables and deferred revenue on the balance sheet appear in operating cash flow. 4. Investing and financing: capex increases PP&E, borrowing and repayments change debt, share issuance and buybacks change equity, and dividends reduce retained earnings, each with the cash movement on the cash flow statement. 5. Cash: the net change in cash at the bottom of the cash flow statement equals the change in cash on the balance sheet, which is what makes the balance sheet balance.

If every balance sheet change other than cash is captured on the cash flow statement, the ending cash is exactly the figure that keeps assets equal to liabilities plus equity.

In a three-statement model, what makes the balance sheet balance, and what do you do when it doesn't?

The balance sheet balances when every flow is recorded on both sides. Net income goes to retained earnings; each non-cash charge reduces or creates a balance sheet item; every change in a non-cash balance sheet account appears on the cash flow statement; and the ending cash from the cash flow statement becomes the cash line. Because the cash flow statement is the accounting equation rearranged (change in cash equals the change in liabilities and equity less the change in non-cash assets), if all those links are in place, cash comes out at exactly the figure that balances the sheet.

When it doesn't balance, the size and pattern of the difference point to the error:

- Difference equal to one item: a flow recorded on one statement but not linked to the balance sheet, such as capex in the cash flow statement but not added to PP&E. - Difference equal to twice an item: a sign flipped, such as an increase in payables treated as a use of cash. - Difference that grows by the same amount each year: a recurring flow linked on one side only, such as depreciation not deducted from PP&E. - Constant difference from the first projected year: the opening balance sheet doesn't balance, or a one-off item wasn't fully linked.

You trace and fix the link; you never plug the difference into cash or "other assets", because that hides the error, and a balancing model can still be wrong if its assumptions are unrealistic.

Beginning retained earnings are $500, net income $80, dividends $30, and the company buys back $20 of shares and holds them in treasury. What are ending retained earnings?

Ending retained earnings are $550.

$500 + $80 of net income - $30 of dividends = $550.

The buyback doesn't touch retained earnings here: shares held in treasury are recorded as treasury stock, a separate negative line in equity, so total equity falls by the $20 while retained earnings stay at $550. (If the company retired the shares instead, part or all of the cost above par value could be charged to retained earnings, which is why retained earnings aren't comparable across companies after large buybacks.)

You have two consecutive balance sheets but no income statement. How would you work out net income?

Through the retained earnings roll-forward. Ending retained earnings equal beginning retained earnings plus net income less dividends (and less any other direct charges), so:

$\text{Net income} = \text{Ending RE} - \text{Beginning RE} + \text{Dividends}$

Dividends paid can be estimated from the change in dividends payable and any disclosure, or assumed to be zero for a private company that doesn't pay them. Then check for items that move retained earnings without passing through net income: buybacks charged to retained earnings when shares are retired, adoption of a new accounting standard, or transactions with minority holders.

To go further and rebuild parts of the income statement, use the other roll-forwards: capex less the increase in net PP&E gives depreciation (if capex is known and there were no disposals or impairments), the change in accumulated depreciation gives it directly, and changes in tax balances hint at the tax charge. Revenue and margins can't be recovered from balance sheets alone, but net income can, within the limits of those adjustments.

Beginning PP&E is $500, capex $80, depreciation $60, and equipment with a $20 book value is sold. What is ending PP&E?

Ending net PP&E is $500.

$\text{Ending PP\&E} = \text{Beginning} + \text{Capex} - \text{Depreciation} - \text{Disposals}$

$500 + $80 - $60 - $20 = $500.

The disposal comes off at its book value, not the sale price: any difference between the proceeds and the $20 is a gain or loss on the income statement, and the full proceeds appear in investing cash flow. Impairments and acquired PP&E would also move the balance. In a model, the roll-forward is how capex from the cash flow statement and depreciation from the income statement reach the balance sheet.

If you could use only one financial statement to judge a company's health, which would you pick?

The cash flow statement.

- It is the hardest to shape: cash received and paid depends on fewer estimates and judgments than revenue and expenses. - It contains the income statement in summary: under the indirect method it starts from net income, so the bottom line is on the first row, followed by the non-cash charges and working capital movements. - It measures survival: companies fail when they run out of cash, not when they report a loss, and only the cash flow statement shows whether operations fund the business, what it spends on capex, and whether it relies on borrowing or equity raises.

The trade-off is that it says little about the level of assets and debt, and cash can be lumpy year to year. For a stable, mature business, some would argue for the income statement, but for judging health, cash is the better single test.

If you could use only two of the three statements, which two and why?

The income statement and the balance sheet, because together they let you rebuild the cash flow statement, but not the other way around.

Net income comes from the income statement, and depreciation and other non-cash items appear there or can be inferred from changes in balance sheet accounts. Working capital movements, capex (the change in net PP&E plus depreciation), borrowing and repayments, share issuance and dividends all show up as changes between the opening and closing balance sheets.

The reverse doesn't work: the income statement and cash flow statement can't reproduce a balance sheet, because neither records the opening levels of assets and liabilities, such as how much debt or cash the company has.

The rebuilt cash flow statement is an approximation, since acquisitions, currency moves and non-cash transactions blur the balance sheet changes, but it is a good one.

Reviewing a company for an acquisition, which one line item would you pick from each statement?

I'd pick the items that drive price, financing and cash generation:

1. Income statement: EBITDA. It is the earnings base most acquisitions are priced on, through an EV/EBITDA multiple, and the base lenders size acquisition debt against. (If EBITDA isn't a line, operating income plus D&A.) 2. Balance sheet: net debt. It bridges enterprise value to the equity value the buyer actually pays for, and it shows how much leverage the target already carries. 3. Cash flow statement: free cash flow, or operating cash flow less capex. It shows whether EBITDA really turns into cash after reinvestment and working capital, which determines how much debt the deal can support and how quickly it can be repaid.

For a high-growth target I might swap EBITDA for revenue growth, and for a capital-intensive one free cash flow for capex, because those are the figures that would drive the price.

Walk me through a $10 increase in depreciation at a 25% tax rate.

Net income falls by $7.50, cash rises by $2.50, and the balance sheet balances. (This assumes the extra depreciation is also deductible for tax.)

1. Income statement: operating income and pre-tax income fall by $10. Taxes fall by $2.50 (25% x $10), so net income falls by $7.50. 2. Cash flow statement: net income is down $7.50, but depreciation is a non-cash expense, so the $10 is added back. Cash from operations, and cash overall, rise by $2.50, the tax saved. 3. Balance sheet: cash is up $2.50 and net PP&E is down $10, so total assets fall by $7.50. On the other side, retained earnings fall by $7.50. Both sides are down $7.50.

If only book depreciation changed and tax depreciation didn't (for example after a change in useful-life estimate), cash taxes wouldn't change: the $2.50 would be a deferred tax effect, and cash would be unchanged.

Walk me through $40 of stock-based compensation (25% tax, deductible when the awards vest).

Net income falls by $30 and cash doesn't change; retained earnings fall by $30 while paid-in capital rises by $40, so total equity rises by $10.

1. Income statement: $40 of compensation expense, spread across cost of revenue, R&D and SG&A, lowers pre-tax income by $40. The deduction comes at vesting, so the company records a $10 deferred tax benefit; net income falls by $30. 2. Cash flow statement: net income down $30, add back the $40 of non-cash SBC, subtract the $10 deferred tax benefit (no tax has been saved in cash yet). Cash is unchanged. 3. Balance sheet: deferred tax asset up $10. Additional paid-in capital up $40 (the awards will be settled in shares), retained earnings down $30, so equity rises by $10. Assets +$10 = equity +$10.

The common shortcut assumes the deduction comes immediately, so cash rises by $10 and there's no deferred tax asset. Either way, SBC uses no cash, but it isn't free: the cost is borne by existing shareholders through dilution, or through cash buybacks to offset it.

A company impairs $100 of PP&E (25% tax). Walk me through the statements, and does it save cash taxes now?

Net income falls by $75, but cash doesn't change: an impairment of an asset still in use usually isn't deductible until the asset is sold or abandoned, so the tax saving is deferred.

1. Income statement: a $100 impairment charge lowers pre-tax income by $100. Current tax is unchanged, but the company records a $25 deferred tax benefit for the future deduction, so net income falls by $75. 2. Cash flow statement: net income down $75, add back the $100 non-cash impairment, subtract the $25 deferred tax benefit. Operating cash flow, and cash, are unchanged. 3. Balance sheet: PP&E down $100; deferred taxes move by $25 in the company's favor (a deferred tax asset up, or an existing deferred tax liability down), so net assets fall by $75; retained earnings fall by $75.

If the write-down were deductible immediately, net income would be the same and cash would rise by $25. Either way, an impairment is a non-cash accounting charge: it records that the asset is worth less than its book value and lowers future depreciation, but it doesn't change the cash the business generates.

A company buys $100 of inventory on credit, then sells all of it for $140 in cash (25% tax). Walk me through both steps.

Step 1, the purchase on credit: only the balance sheet moves.

1. Income statement: no effect; inventory is an asset until it is sold. 2. Cash flow statement: no cash moves (the inventory increase and the payables increase offset in working capital). 3. Balance sheet: inventory up $100, accounts payable up $100.

Step 2, the sale for cash:

1. Income statement: revenue of $140, COGS of $100, pre-tax income of $40, tax of $10, net income up $30. 2. Cash flow statement: net income up $30, plus the $100 decrease in inventory (a source of cash), so operating cash flow rises by $130. 3. Balance sheet: cash up $130, inventory down $100, so assets rise by $30; retained earnings rise by $30. Payables are still $100 until the supplier is paid.

When the supplier is paid, cash and payables both fall by $100. Over the whole cycle the company keeps the $30 of after-tax profit; the timing of cash depends on when customers pay and when suppliers are paid.

A company sells $200 of services on credit, with $80 of costs paid in cash (25% tax), then collects the receivable. Walk me through both steps.

Step 1, the sale on credit: profit is recorded, but the customer hasn't paid.

1. Income statement: revenue $200, costs $80, pre-tax income $120, tax $30, net income up $90. 2. Cash flow statement: net income up $90, less the $200 increase in accounts receivable, so operating cash flow is -$110: the costs and tax were paid, but the revenue hasn't been collected. 3. Balance sheet: receivables up $200, cash down $110, so assets rise by $90; retained earnings rise by $90.

Step 2, collection:

1. Income statement: no effect; the revenue was already recorded. 2. Cash flow statement: the $200 decrease in receivables is a source of cash, so operating cash flow is +$200. 3. Balance sheet: cash up $200, receivables down $200.

Across both steps cash rises by $90, exactly the net income: the accrual only shifted the timing.

Accrued wages rise by $100 (25% tax), then are paid. Walk me through both steps.

Step 1, wages earned but not yet paid:

1. Income statement: $100 of wage expense; pre-tax income falls by $100, tax by $25, net income by $75. 2. Cash flow statement: net income down $75, plus the $100 increase in accrued liabilities (a source of cash, because the expense hasn't been paid), so operating cash flow rises by $25, the tax saved. 3. Balance sheet: cash up $25; accrued liabilities up $100 and retained earnings down $75. Assets +$25 = liabilities +$100 - equity $75.

Step 2, the wages are paid:

1. Income statement: no effect; the expense was recorded in step 1. 2. Cash flow statement: the $100 decrease in accrued liabilities is a use of cash. 3. Balance sheet: cash down $100, accrued liabilities down $100.

Overall cash falls by $75, the after-tax cost of the wages, matching the change in net income once the accrual unwinds.

A company collects $1,200 upfront for a 12-month subscription. Walk me through the statements at collection and after three months (no costs, 25% tax, taxes follow book).

At collection, the cash arrives before any revenue is earned:

1. Income statement: no effect; nothing has been delivered yet. 2. Cash flow statement: the $1,200 increase in deferred revenue is a source of cash in operating activities, so cash rises by $1,200. 3. Balance sheet: cash up $1,200; deferred revenue, a liability, up $1,200.

After three months, a quarter of the service has been delivered:

1. Income statement: revenue of $300; tax of $75; net income up $225. 2. Cash flow statement: net income up $225, less the $300 decrease in deferred revenue (that cash was already collected), so operating cash flow is -$75, the tax paid. 3. Balance sheet: cash down $75; deferred revenue down $300 to $900, retained earnings up $225. Assets -$75 = liabilities -$300 + equity $225.

This is why subscription businesses often show operating cash flow well ahead of net income: customers fund the business in advance, and the liability unwinds into revenue as the service is delivered.

A company buys $100 of equipment with cash, 10-year life. Walk me through the statements at purchase and after one year (25% tax).

At purchase, cash is swapped for PP&E and the income statement doesn't move:

1. Income statement: no effect; buying an asset isn't an expense. 2. Cash flow statement: capex of $100 in investing activities, so cash falls by $100. 3. Balance sheet: cash down $100, PP&E up $100. Total assets are unchanged.

After one year, the asset is depreciated by $10 ($100 over 10 years):

1. Income statement: depreciation of $10 lowers pre-tax income by $10; tax falls by $2.50, so net income falls by $7.50. 2. Cash flow statement: net income down $7.50, depreciation of $10 added back, so operating cash flow rises by $2.50. 3. Balance sheet: cash up $2.50, PP&E down $10 to $90; retained earnings down $7.50. Both sides fall by $7.50.

The cost reaches the income statement gradually through depreciation, while the cash left on day one, which is why capex and depreciation tell different stories in any single year.

A distressed company sells a factory with a $100 book value for $80 (25% tax). Walk me through the statements.

The sale produces a $20 loss; net income falls by $15 and cash rises by $85.

1. Income statement: a $20 loss on sale (book value $100 less proceeds $80). Assuming the loss is deductible, taxes fall by $5, so net income falls by $15. 2. Cash flow statement: start with net income down $15 and add back the $20 loss, because it is non-cash and the cash from the sale belongs in investing: operating cash flow is up $5 (the tax saved). Investing activities show the $80 of proceeds. Cash rises by $85. 3. Balance sheet: cash up $85, PP&E down $100, so assets fall by $15; retained earnings fall by $15. It balances.

The add-back is the key step: without it, the loss would be counted once in operating cash flow and the proceeds again in investing, and the cash change would be wrong.

A company buys land for $100 and sells it three years later for $140 (25% tax). Walk me through the sale.

Land isn't depreciated, so its book value is still $100 when it is sold, and the gain is $40.

1. Income statement: a $40 gain on sale; tax of $10, so net income rises by $30. 2. Cash flow statement: net income up $30; subtract the $40 gain, because the cash belongs in investing, so operating cash flow is -$10 (the tax paid on the gain). Investing activities show $140 of proceeds. Cash rises by $130. 3. Balance sheet: cash up $130, land down $100, so assets rise by $30; retained earnings rise by $30. It balances.

Over the three years before the sale nothing happened on the statements, because land has an indefinite life: no depreciation, no tax shield.

A company borrows $100 at 10% and pays a year of interest in cash (25% tax). Walk me through the statements.

When it borrows, only the balance sheet and cash flow statement move:

1. Income statement: no effect; borrowing isn't income. 2. Cash flow statement: $100 of debt raised in financing activities, so cash rises by $100. 3. Balance sheet: cash up $100, debt up $100.

After a year of interest:

1. Income statement: interest expense of $10 lowers pre-tax income by $10; tax falls by $2.50, so net income falls by $7.50. 2. Cash flow statement: net income down $7.50. Interest was paid in cash, so there's nothing to add back; under US GAAP interest paid sits in operating activities. Cash falls by $7.50. 3. Balance sheet: cash down $7.50; retained earnings down $7.50. Debt stays at $100 because no principal was repaid.

The after-tax cost of the debt is $7.50, or 7.5%, because interest is deductible. Repaying the principal later would reduce cash and debt by $100 in financing, with no income statement effect.

A company has a $100 PIK note at 10%. Walk me through year one (25% tax).

PIK interest is an expense that uses no cash: it is added to the principal instead of being paid. Assuming it is deductible as it accrues:

1. Income statement: interest expense of $10; tax falls by $2.50, so net income falls by $7.50. 2. Cash flow statement: net income down $7.50, plus the $10 of non-cash PIK interest added back, so operating cash flow rises by $2.50 (the tax saved). Cash rises by $2.50. 3. Balance sheet: cash up $2.50; the note grows by $10 to $110, and retained earnings fall by $7.50. Assets up $2.50 = liabilities up $10 less equity down $7.50.

In year two, interest accrues on $110, so the expense is $11: PIK debt compounds. That is why it eases cash flow today but raises the debt the company must eventually repay or refinance, and why bankers look at both interest expense and interest paid. (The deduction can be limited, for example by Section 163(j), in which case the tax saving is smaller.)

A struggling company receives a $100 bailout. Walk me through the statements.

It depends on the form the bailout takes.

If it is an equity investment (the usual case, for example a government buying shares):

1. Income statement: no effect; raising capital isn't income. 2. Cash flow statement: $100 of shares issued in financing activities, so cash rises by $100. 3. Balance sheet: cash up $100; common stock and additional paid-in capital up $100.

If it is a loan, cash and debt both rise by $100, and from then on interest expense reduces net income and cash. If it is preferred stock, the cash comes in the same way, but the shares sit in equity, mezzanine (temporary) equity or liabilities depending on their redemption terms, and any preferred dividends reduce the income available to common shareholders.

Walk me through a $10 cash dividend.

A dividend is a distribution to owners, not an expense, so it never touches the income statement.

1. Income statement: no effect; net income is unchanged. 2. Cash flow statement: $10 of dividends paid in financing activities, so cash falls by $10. 3. Balance sheet: cash down $10; retained earnings down $10. Both sides fall by $10.

If the dividend is declared before the period end but paid after, retained earnings fall at declaration and a dividends payable liability sits on the balance sheet until the cash goes out.

A company borrows $200 to pay a special dividend. Walk me through day one and the first year at 10% interest (25% tax).

This is a dividend recapitalization: equity is swapped for debt.

Day one:

1. Income statement: no effect. 2. Cash flow statement: in financing activities, $200 of debt raised and $200 of dividends paid, so cash is unchanged. 3. Balance sheet: debt up $200; retained earnings down $200. Total liabilities plus equity is unchanged, and equity can easily turn negative.

After one year:

1. Income statement: interest of $20; tax falls by $5, so net income falls by $15. 2. Cash flow statement: net income down $15, interest paid in cash, so cash falls by $15. 3. Balance sheet: cash down $15; retained earnings down $15. Debt stays at $200 unless principal is repaid.

The company is now more leveraged and pays $15 a year after tax to fund a one-off return of cash, which is why lenders size recaps against free cash flow and leverage capacity.

Rank buying equipment with cash, an operating lease and a finance lease by their effect on EBITDA, EBIT and net income in year one.

Assume the same asset and life in each case and US GAAP (ASC 842), where both lease types put a right-of-use asset and a lease liability on the balance sheet.

1. EBITDA: buying and a finance lease are tied highest, and the operating lease is lowest. The purchase creates depreciation and the finance lease creates amortization plus interest, all below EBITDA, while the operating lease's single straight-line lease cost sits in operating expenses. 2. EBIT: buying and the finance lease are roughly tied, since depreciation and right-of-use amortization are similar; the operating lease is lowest, because its lease cost includes the financing element that a finance lease records as interest below EBIT. 3. Net income: buying with cash is highest (only depreciation, ignoring the interest the cash could have earned). The operating lease comes next, with a flat cost each year. The finance lease is lowest in year one, because its interest is front-loaded: it is largest when the liability is largest, so amortization plus interest exceeds the straight-line operating lease cost early on and falls below it later.

Cash flow differs too: an operating lease puts the whole payment in operating cash flow, a finance lease splits it between interest (operating) and principal (financing), and the purchase puts the full cost in investing on day one. That's why bankers adjust for leases consistently before comparing EBITDA multiples or leverage.

Tax depreciation exceeds book depreciation by $40 (25% tax). Walk me through the statements.

Net income doesn't change, but cash rises by $10 and a deferred tax liability of $10 appears.

1. Income statement: book depreciation is unchanged, so pre-tax income and total tax expense don't change. Inside the tax line, current tax falls by $10 (25% x $40, the extra deduction on the tax return) and deferred tax expense rises by $10. Net income is unchanged. 2. Cash flow statement: net income unchanged; the $10 of deferred tax expense is non-cash, so it is added back. Operating cash flow, and cash, rise by $10. 3. Balance sheet: cash up $10; deferred tax liability up $10. It balances.

The $10 is tax postponed, not saved: when tax depreciation drops below book depreciation in later years, the liability reverses and cash taxes are higher. For a company that keeps investing, though, the DTL can grow for years, which is why bankers look at cash taxes, not just the tax expense, when forecasting free cash flow.

A company makes a $100 cash acquisition. Walk me through the statements.

At closing, the acquisition is almost entirely a balance sheet and investing cash flow event.

1. Income statement: essentially no effect at closing, apart from deal fees, which are expensed as incurred. The target's results are consolidated only from the closing date onward. 2. Cash flow statement: $100 paid for the acquisition (net of the target's cash) in investing activities, so cash falls by $100. 3. Balance sheet: cash down $100; the target's assets and liabilities are added at fair value, including newly identified intangibles, and any excess of the $100 price over the fair value of the net assets is recorded as goodwill. Deferred tax liabilities appear on write-ups in a stock deal. The buyer's equity doesn't change, because it paid cash rather than issuing shares.

After closing, the target's revenue and costs flow into the income statement, together with the purchase accounting charges: amortization of acquired intangibles, higher depreciation on written-up PP&E and the inventory step-up flowing through COGS. If the deal were funded with debt, cash would be raised in financing and interest would follow; if with stock, the buyer's equity would rise instead of cash falling.

How does an inventory step-up in an acquisition affect gross margin after closing?

It depresses gross margin temporarily, with no cash effect.

In the purchase price allocation, the target's inventory is recorded at fair value, roughly its selling price less the costs and a reasonable profit for selling it, which is usually well above the target's own cost. When that inventory is sold after closing, cost of goods sold reflects the higher stepped-up value, so gross profit is lower than the target would have reported on the same sales. For example, inventory that cost $60 but is valued at $90 adds $30 of extra COGS when sold, and $22.50 less net income at a 25% tax rate (through a deferred tax effect, since the tax basis is unchanged in a stock deal).

Because inventory turns over within months, the effect disappears quickly, typically within the first quarter or two. That's why acquirers report it separately and bankers remove it from post-closing margins when judging the combined company's run-rate profitability.

A company owns 25% of a business that earns $200 and pays $80 of dividends. Walk me through the owner's statements (ignore taxes).

With a 25% stake the owner has significant influence, so it uses the equity method: it records its share of the earnings, but cash arrives only through dividends.

1. Income statement: equity method income of 25% x $200 = $50, so net income rises by $50. 2. Cash flow statement: net income up $50; subtract the $50 of equity income because it is non-cash, then add the dividends received, 25% x $80 = $20 (operating activities under US GAAP). Cash rises by $20. 3. Balance sheet: cash up $20; the investment rises by $50 of income less $20 of dividends, a net $30. Assets rise by $50, matching the $50 increase in retained earnings.

Note that the dividend creates no income for the owner, because its share of the profit behind it was already recognized: it simply converts part of the investment into cash. (In practice the owner would also record deferred tax on its share of undistributed earnings.)

A company buys a $100 factory with 10% debt (10-year life, 25% tax). Walk me through the start of year 1, the end of year 1, and the end of year 2 when the factory is abandoned and the loan repaid.

Start of year 1, the purchase:

1. Income statement: no effect. 2. Cash flow statement: $100 of capex in investing and $100 of debt raised in financing, so cash is unchanged. 3. Balance sheet: PP&E up $100, debt up $100.

End of year 1: $10 of interest and $10 of depreciation.

1. Income statement: pre-tax income falls by $20, tax by $5, net income by $15. 2. Cash flow statement: net income down $15, depreciation of $10 added back, so cash falls by $5 (the after-tax interest of $7.50 less the $2.50 depreciation tax shield). 3. Balance sheet: cash down $5, PP&E down to $90, so assets fall by $15; debt stays at $100; retained earnings fall by $15. It balances.

End of year 2: another $10 of interest and $10 of depreciation, then the factory is abandoned, writing off its remaining $80 (deductible because the asset is abandoned), and the loan is repaid.

1. Income statement: interest $10, depreciation $10 and the $80 write-off reduce pre-tax income by $100; tax falls by $25; net income falls by $75. 2. Cash flow statement: net income down $75, add back $10 of depreciation and the $80 non-cash write-off, so operating cash flow is +$15; repaying the debt is -$100 in financing; cash falls by $85. 3. Balance sheet: cash down $85 and PP&E down $90 to zero, so assets fall by $175; debt falls by $100 and retained earnings by $75. Both sides fall by $175.

Across the two years, cash falls by $90 in total and equity by $90: the after-tax cost of the interest and of the lost $100 investment.

What are the five steps of revenue recognition under ASC 606?

1. Identify the contract with the customer. 2. Identify the performance obligations, the distinct goods or services promised. 3. Determine the transaction price, including estimates of variable consideration such as discounts, rebates or bonuses. 4. Allocate the price to the performance obligations, based on their standalone selling prices. 5. Recognize revenue when (or as) each obligation is satisfied, by transferring control to the customer, either at a point in time or over time.

The judgments that matter to bankers sit in steps 2, 3 and 5: how a bundled contract is split (hardware vs software vs service), how much variable consideration is booked upfront, and whether revenue is recognized at once or over time. Those choices move the timing of revenue and margins between periods, which is why revenue recognition is a focus of quality of earnings work.

What is the difference between accounts receivable, deferred revenue and unbilled (accrued) revenue?

All three come from timing gaps between earning revenue, billing and collecting cash:

- Accounts receivable: revenue has been earned and the company has an unconditional right to be paid; only time stands between it and the cash. It is an asset. - Unbilled revenue (a contract asset): revenue has been earned, but the right to payment is still conditional, for example on reaching a billing milestone or finishing more work. It is an asset that turns into a receivable when the company can bill. - Deferred revenue (a contract liability): the customer has paid, or the payment is unconditionally due, before the company has delivered. It is a liability that turns into revenue as the company performs.

They matter for cash and quality of earnings: growing deferred revenue means customers fund the business in advance, while a growing contract asset means revenue is being recognized ahead of the right to bill, which ties up cash and deserves a look at the underlying contracts.

A $2,000 fixed-price contract has $1,500 of expected costs, and $600 has been incurred so far. How much revenue and profit are recognized to date?

Revenue of $800 and profit of $200.

Under the cost-to-cost method, progress is the share of total expected costs incurred so far:

1. Percentage complete: $600 / $1,500 = 40%. 2. Revenue to date: 40% x $2,000 = $800. 3. Profit to date: $800 - $600 of costs = $200, which is also 40% of the expected total profit of $500.

The estimate drives the result: if expected total costs rise, the percentage complete and cumulative profit are recalculated, and the difference is booked in the current period as a cumulative catch-up. If the contract becomes loss-making, the whole expected loss is recognized immediately. That's why bankers look closely at estimate changes and at contract assets building up faster than billings.

When do you capitalize a cost rather than expense it, and how does each affect the statements?

A cost is capitalized when it creates a future benefit beyond the current period, typically an asset used for more than a year: equipment, buildings, major improvements, certain software development costs. It is expensed when it is consumed in the period or has no clear future benefit: wages, rent, repairs and maintenance, marketing and, under US GAAP, most R&D.

The choice changes where the cost shows up, not the cash:

Expensed: the full cost hits the income statement now, reducing EBITDA, EBIT and net income, and the cash outflow sits in operating activities.

Capitalized: the cost becomes an asset and reaches the income statement gradually through depreciation or amortization, below EBITDA. EBITDA is untouched, EBIT and net income fall only by that year's depreciation, and the cash outflow sits in investing activities, so operating cash flow is higher.

Total cash and free cash flow are the same either way. That's why bankers watch companies that capitalize aggressively: EBITDA and operating cash flow look better, while capex quietly grows.

A new rule lets a company capitalize R&D. What happens to EBITDA, net income, cash flow and valuation?

- EBITDA rises, by the full amount of R&D now capitalized, because the spending no longer runs through operating expenses; it comes back later as amortization, below EBITDA. - Net income rises in the near term, by the capitalized amount less its first-year amortization, after tax. For a company whose R&D is growing, net income stays higher for as long as spending grows faster than amortization. - Operating cash flow rises and investing cash flow falls by the same amount, because the spending moves to capex. Total cash and free cash flow don't change (assuming tax treatment is unchanged), since the company spends the same money. - Valuation shouldn't change in a DCF, because unlevered free cash flow is the same. But multiples-based value can mislead: EV/EBITDA looks cheaper, so the company must be compared with peers on a consistent basis, by expensing the R&D again or by moving to free cash flow measures.

The broader point: accounting choices that move costs between the income statement and the balance sheet change reported earnings and EBITDA, not the cash the business generates.

When can development costs be capitalized under IFRS?

Under IAS 38, research costs are always expensed, but development costs must be capitalized once a company can demonstrate all six criteria:

1. Technical feasibility of completing the asset. 2. The intention to complete it and use or sell it. 3. The ability to use or sell it. 4. Probable future economic benefits, such as a market for the product. 5. Adequate resources (technical, financial and other) to finish it. 6. The ability to measure reliably the costs attributable to it.

Before all six are met, development costs are expensed; after that, they are capitalized and amortized over the expected life of the product, and tested for impairment.

Under US GAAP, by contrast, R&D is expensed as incurred, apart from narrow exceptions such as certain software costs. So IFRS reporters with heavy development spending, such as carmakers, show higher EBITDA than US peers. To compare them, a banker deducts the capitalized development costs from EBITDA and removes them from capex; free cash flow doesn't change.

A company buys one unit each at $30, $40 and $50, then sells two for $60 each. What are COGS and gross profit under FIFO and LIFO?

Revenue is $120 either way; the methods differ in which costs go to COGS.

FIFO (first in, first out): the two oldest units are sold, $30 + $40 = $70 of COGS, so gross profit is $50. Ending inventory is the newest unit, $50.

LIFO (last in, first out): the two newest units are sold, $50 + $40 = $90 of COGS, so gross profit is $30. Ending inventory is the oldest unit, $30.

With rising costs, LIFO gives lower profit, lower taxes and therefore more cash, but an inventory balance that understates current cost. FIFO gives higher profit and a more current inventory value, but more tax. The $20 gap in ending inventory is the LIFO reserve. LIFO is allowed under US GAAP but prohibited under IFRS, so bankers convert LIFO users to FIFO using the reserve before comparing them with FIFO peers.

A company on LIFO with a $40 LIFO reserve switches to FIFO (25% tax). What happens to the statements?

A change in accounting principle is applied retrospectively, as if FIFO had always been used.

1. Balance sheet: inventory rises by the $40 reserve, to its FIFO value. Because taxes on that difference will now come due, a $10 tax liability is recorded (in the US, the catch-up is generally spread over several years for tax, so it sits mostly as a deferred tax liability). Retained earnings rise by the after-tax $30, through the opening balance and the restated prior periods. 2. Income statement: prior periods are restated on a FIFO basis. Going forward, if costs keep rising, COGS is lower and gross profit and net income are higher than under LIFO. 3. Cash flow statement: no cash at the switch, but from then on the company pays more tax: the deferred LIFO benefit is recaptured over the next few years, and future taxable income is higher in an inflationary environment.

So the switch flatters reported earnings and book value and costs real cash in taxes. Companies usually make it after expanding abroad, where LIFO isn't allowed, or when they decide the tax benefit no longer justifies the lower reported profits.

A company writes off $100 of obsolete inventory and scraps it (25% tax, deductible on disposal). Walk me through the statements.

Net income falls by $75, cash rises by $25, and inventory falls by $100.

1. Income statement: the $100 write-off is usually charged to cost of goods sold, so pre-tax income falls by $100. Because the stock is scrapped, the loss is deductible now, so taxes fall by $25 and net income falls by $75. 2. Cash flow statement: net income down $75, plus the $100 non-cash write-off added back (or shown as the decrease in inventory), so operating cash flow rises by $25, the tax saved. 3. Balance sheet: inventory down $100, cash up $25, so assets fall by $75; retained earnings fall by $75. It balances.

The tax assumption matters: if the inventory were only written down to a lower value and kept, a US company generally couldn't deduct the reserve until the goods are sold or scrapped, so there would be no cash saving yet, just a $25 deferred tax asset.

What is working capital, and how do bankers define it differently from the textbook?

The textbook definition is current assets minus current liabilities, a measure of short-term liquidity.

Bankers usually mean operating working capital (often called net working capital): the current assets and liabilities that come from running the business, typically receivables, inventory and prepaid expenses, less payables, accrued expenses and deferred revenue. They exclude:

- Cash and short-term investments, which are treated as part of net debt or valued separately. - Short-term debt and the current portion of long-term debt, which are financing, not operations. - Often income taxes, dividends payable and other non-operating items, which are handled separately.

The banker's version is what moves in a DCF and in operating cash flow: an increase is a use of cash. It is also what the working capital peg in an acquisition is measured on, so the exact definition is negotiated line by line in a deal.

Is negative working capital bad?

Not necessarily; it depends on why it is negative.

Often it's a strength. Businesses that collect from customers before paying suppliers run negative working capital as a feature of their model: grocers and discount retailers that sell for cash and pay suppliers in 30 to 60 days, restaurants, and subscription software companies that collect annual fees upfront (deferred revenue). For them, customers and suppliers fund the business, and growth actually releases cash.

Sometimes it's a warning. Negative working capital can also mean a company is stretching suppliers because it is short of cash, is struggling to pay bills as they fall due, or has large near-term obligations it can't cover.

To tell them apart, look at the drivers: a short or negative cash conversion cycle with stable payable days and strong cash flow is healthy; payable days rising sharply, falling cash and overdue liabilities point to stress. In valuation, a business with structurally negative working capital needs less cash to grow, which supports free cash flow.

DSO is 40, DIO 60 and DPO 30, with COGS of $730. What is the cash conversion cycle, and how much cash is freed if DPO rises to 45?

The cash conversion cycle falls from 70 to 55 days, freeing about $30 of cash.

1. Cash conversion cycle: DSO + DIO - DPO = 40 + 60 - 30 = 70 days: the time cash is tied up between paying for inventory and collecting from customers. 2. After the change: 40 + 60 - 45 = 55 days. 3. Cash freed: payables are measured against COGS, and $730 / 365 = $2 a day. Fifteen more days of payables is 15 x $2 = $30 that stays in the company.

It is a one-time release, not a recurring gain: payables can't be stretched forever, and pushing suppliers too far raises prices or supply risk. Bankers treat a large working capital release as non-recurring when estimating sustainable free cash flow.

How does accelerated depreciation compare with straight-line on the statements and in a DCF?

Both methods expense the same total over the asset's life; only the timing differs.

- Income statement: accelerated depreciation (such as double-declining balance) charges more in the early years and less later, so EBIT and net income are lower early and higher later. EBITDA is unaffected either way. - Balance sheet: net PP&E falls faster under the accelerated method. - Cash: the book method itself doesn't change cash. Cash taxes follow tax depreciation, which in the US is generally accelerated (MACRS, plus bonus depreciation when available) whatever method the company uses for its books; the gap between book and tax depreciation creates a deferred tax liability.

In a DCF, what matters is tax depreciation: accelerated deductions pull tax savings forward, and because earlier cash is worth more, they raise present value. If a model calculates taxes on book EBIT, switching the book method to accelerated would show the same effect, which is why a careful model uses the tax depreciation schedule (or the cash tax rate) for the tax line. Most companies use straight-line for their books because it is simple and gives smoother, higher early earnings.

A company buys $600 of servers and depreciates them over 5 years instead of 3 for its books. What happens to the year-one statements (25% tax, tax depreciation unchanged)?

Net income rises by $60 and cash doesn't change.

1. Income statement: depreciation falls from $200 ($600 over 3 years) to $120 (over 5 years), so pre-tax income rises by $80. Tax expense rises by $20, all deferred, because tax depreciation is unchanged; net income rises by $60. 2. Cash flow statement: net income up $60, but the depreciation add-back is $80 lower and the deferred tax expense adds $20 back, so operating cash flow, and cash, are unchanged. 3. Balance sheet: net PP&E is $80 higher at year end; a $20 deferred tax liability appears; retained earnings are $60 higher.

The point is that useful lives are estimates: a longer life flatters earnings for years without changing the cash the business generates, and the cost catches up later. That is why bankers compare useful-life assumptions across peers and treat EBITDA (unaffected) or EBITDA less capex as the cleaner comparison.

What is the difference between goodwill and other intangible assets, and which are amortized?

Identifiable intangible assets are specific assets that can be separated from the business or arise from contracts or legal rights: customer relationships, developed technology, patents, trademarks, licenses. Goodwill is what's left of an acquisition price after every identifiable asset and liability is valued: expected synergies, the assembled workforce and the going-concern value that can't be recognized separately.

On amortization under US GAAP:

- Finite-lived intangibles (customer relationships, technology, patents) are amortized, usually straight-line, over their useful lives. - Indefinite-lived intangibles (such as an established trademark that can be renewed indefinitely) are not amortized but tested for impairment at least annually. - Goodwill is not amortized (except under a private company alternative) and is tested for impairment at least annually.

The distinction matters because the more of the price allocated to finite-lived intangibles, the larger the amortization that reduces future earnings, while goodwill affects earnings only through impairments. Note too that most intangibles appear on the balance sheet only when acquired: internally built brands and technology are expensed as created.

How do acquired intangibles affect GAAP EPS, and do they change a company's value?

They lower GAAP EPS without changing value.

After an acquisition, finite-lived intangibles such as customer relationships and technology are amortized over their useful lives. That amortization is a non-cash expense that reduces operating income and net income for years, so GAAP EPS falls, especially in the first years after a large deal. In a stock acquisition, amortization usually isn't deductible for tax, so it doesn't even save cash taxes (in an asset deal or with a 338(h)(10) election, it is deductible and does).

But the cash flows of the combined business are the same whether the price was allocated to intangibles or to goodwill, so a DCF value doesn't change. That's why acquirers report adjusted EPS excluding acquisition-related amortization, why analysts often value acquisitive companies on cash EPS or EBITDA, and why comparing GAAP P/E ratios between an acquisitive company and an organically grown peer can mislead.

Walk me through a $100 goodwill impairment that is not tax deductible.

Net income falls by the full $100, cash doesn't change, and goodwill falls by $100.

1. Income statement: a $100 impairment charge. Because it isn't deductible (and goodwill from a stock acquisition has no tax basis, so there is no deferred tax either), there is no tax benefit, and net income falls by $100. 2. Cash flow statement: net income down $100, plus the $100 non-cash charge added back. Cash is unchanged. 3. Balance sheet: goodwill down $100; retained earnings down $100. It balances.

With no tax shield, the after-tax cost equals the full pre-tax charge. (Goodwill from an asset deal is amortized for tax, so an impairment there can carry a deferred tax effect.)

Why would a company impair goodwill, and how is it tested?

Goodwill is the premium paid in an acquisition over the fair value of the identifiable net assets. Under US GAAP it isn't amortized; instead it is tested for impairment at least once a year, and whenever events suggest it may be impaired. A company impairs it when the business it bought is worth less than its carrying amount: performance below the acquisition plan, lower industry multiples, higher discount rates, a falling share price, or the loss of a major customer.

The test works at the level of the reporting unit (a segment or one level below):

Optional qualitative step: the company can first assess whether it is more likely than not that the unit's fair value is below its carrying amount. If not, no further test is needed.

Quantitative test: compare the reporting unit's fair value, usually from a DCF and market multiples, with its carrying amount including goodwill. If the carrying amount is higher, the impairment equals the excess, capped at the goodwill balance.

An impairment uses no cash and doesn't change the business's cash generation, but it is a verdict that the buyer overpaid relative to what the business is now expected to earn. Repeated impairments are a sign of a poor acquisition record.

How do operating and finance leases differ on each statement under ASC 842?

On the balance sheet they look the same: both put a right-of-use asset and a lease liability (the present value of the payments) on the balance sheet. The differences are on the other two statements.

- Income statement: an operating lease records one straight-line lease cost in operating expenses, so it reduces EBITDA. A finance lease records amortization of the right-of-use asset plus interest on the liability, both below EBITDA, and the total is front-loaded, because interest is highest when the liability is largest. - Cash flow statement: operating lease payments are entirely operating cash outflows. Finance lease payments are split: interest in operating activities, principal in financing activities, so finance lessees report higher operating cash flow. - Debt and leverage: finance lease liabilities are generally treated as debt; operating lease liabilities are treated inconsistently across credit agreements, rating agencies and banks' own analyses.

So two companies with identical leases but different classifications report different EBITDA, operating cash flow and leverage. Bankers check the lease note and adjust consistently before comparing multiples.

What makes a lease a finance lease under US GAAP?

A lease is a finance lease if it meets any one of five tests at commencement; otherwise it is an operating lease.

1. Transfer of ownership: ownership passes to the lessee by the end of the term. 2. Purchase option: the lessee has an option to buy the asset that it is reasonably certain to exercise. 3. Lease term: the term covers a major part of the asset's remaining economic life (many companies use 75% as their policy threshold). 4. Present value: the present value of the payments, plus any residual value the lessee guarantees, is substantially all of the asset's fair value (commonly 90%). 5. Specialized asset: the asset is so specialized that it has no alternative use to the lessor at the end of the term.

The logic is that a finance lease is, in substance, a purchase financed with a loan. The label matters to bankers because it decides whether the cost sits above or below EBITDA, how payments split between operating and financing cash flow, and often how credit agreements count the liability.

How does IFRS 16 change the three statements and EBITDA?

IFRS 16 has a single lessee model: almost every lease (apart from short-term and low-value leases) is treated like a finance lease.

1. Balance sheet: a right-of-use asset and a lease liability for the present value of the payments, as under US GAAP. 2. Income statement: the rent-like expense is replaced by depreciation of the right-of-use asset and interest on the liability, both below EBITDA. So EBITDA rises by roughly the full lease payment, and EBIT rises by roughly the interest component. Total expense is front-loaded, so net income is lower in the early years of a lease. 3. Cash flow statement: the principal portion of lease payments moves to financing, so operating cash flow is higher; the interest portion follows the company's policy (operating or financing).

For a retailer, airline or other lease-heavy business, an IFRS reporter therefore shows much higher EBITDA and operating cash flow than a US peer with operating leases, and more debt once lease liabilities are counted. Bankers either move IFRS lease costs back above EBITDA or add lease liabilities to everyone's debt, so that EV/EBITDA and leverage compare like with like.

Accretion on an asset retirement obligation rises by $100 (25% tax; deductible only when the cleanup is paid). Walk me through the statements.

Net income falls by $75, cash doesn't change, and the obligation grows by $100.

An asset retirement obligation (ARO) is recorded at the present value of the future cost of dismantling or cleaning up an asset, such as plugging oil wells. Each year it is accreted: the discount unwinds, so the liability grows toward the full future cost, and the accretion is an operating expense.

1. Income statement: $100 of accretion expense lowers pre-tax income by $100. It isn't deductible until the cleanup is paid, so the company records a $25 deferred tax benefit; net income falls by $75. 2. Cash flow statement: net income down $75, add back the $100 non-cash accretion, subtract the $25 deferred tax benefit. Cash is unchanged. 3. Balance sheet: the ARO liability rises by $100; a $25 deferred tax asset; retained earnings fall by $75. Assets +$25 = liabilities +$100 - equity $75.

The cash comes later, when the work is done. That's why bankers treat large AROs, net of tax, as a debt-like item in valuation, and energy add-back lists often exclude accretion from EBITDA.

Why do companies keep separate tax books, and how does book depreciation differ from tax depreciation?

Because the two sets of rules serve different purposes. GAAP books aim to show investors economic performance, matching costs with revenue. Tax rules aim to raise revenue and encourage behavior, such as investment, so they set their own timing for income and deductions.

Depreciation is the classic difference. For the books, most companies depreciate assets straight-line over their useful lives. For tax, US companies use accelerated depreciation (MACRS), and bonus depreciation can let them deduct most or all of the cost in the first year. So in the early years tax depreciation exceeds book depreciation, taxable income is lower than book income, and the company pays less tax now. The difference reverses later, when tax depreciation runs out but book depreciation continues.

That timing gap is recorded as a deferred tax liability: the tax deferred today that will be paid in later years. Other differences include R&D (expensed for books, capitalized and amortized for US tax), stock-based compensation (deducted at vesting or exercise) and reserves (deducted only when paid), plus permanent differences such as non-deductible fines.

Why does income tax expense differ from the taxes a company actually pays?

Tax expense on the income statement has two parts: current tax, the tax owed on this year's tax return, and deferred tax, the change in deferred tax assets and liabilities from timing differences. Only the current part is (roughly) paid in cash during the year; any timing gap in payment sits in taxes payable or receivable.

So taxes paid differ from tax expense when:

- Timing differences move income or deductions between periods: accelerated tax depreciation, R&D capitalized for tax, stock compensation deducted at vesting, reserves deducted only when paid. - Losses are used: NOLs carried forward reduce cash tax while the tax expense reflects the use of the deferred tax asset. - Payments don't match accrual timing: estimated payments, refunds and settlements of prior years.

The effective tax rate (tax expense over pre-tax income) also differs from the statutory rate because of permanent items: foreign income at different rates, tax credits, non-deductible expenses, and one-offs such as valuation allowance releases. The cash tax rate (taxes paid over pre-tax income) is what matters for free cash flow, so bankers check taxes paid in the supplemental cash flow disclosure and the tax note before forecasting.

Why can a company's effective tax rate differ from the statutory rate?

The effective tax rate is income tax expense divided by pre-tax income. It differs from the statutory rate (21% federal in the US, plus state taxes) mainly because of permanent differences and rate effects, items that change tax for good rather than shifting it between years:

- Foreign earnings taxed at lower (or higher) rates than the US rate. - Tax credits, such as the R&D credit, and special deductions like the foreign-derived intangible income deduction. - Non-deductible expenses, such as government fines and some executive compensation, and non-taxable income. - State taxes, which add to the federal rate. - Stock-based compensation: excess tax benefits when shares vest above their grant value lower the rate (shortfalls raise it). - One-offs: valuation allowance changes, tax law changes and settlements with tax authorities.

Temporary differences, such as accelerated depreciation, don't change the effective rate, because deferred taxes offset them; they change the cash tax rate instead. Every company discloses a rate reconciliation in its tax note, and bankers use it to separate recurring drivers of the rate from one-offs before forecasting taxes.

What are deferred tax assets and liabilities, and how do they arise?

They arise from temporary differences between book income and taxable income, items recognized in different periods for books and for tax, which reverse over time.

Deferred tax liability (DTL): taxes the company has postponed and will pay later, because taxable income has so far been lower than book income. The main source is faster tax depreciation than book depreciation; another is asset write-ups in a stock acquisition, where book values rise but tax bases don't.

Deferred tax asset (DTA): future tax savings, because taxable income has so far been higher than book income, or because the company has losses to use. Sources include net operating loss carryforwards, reserves and accruals expensed for books but deductible only when paid, R&D capitalized for tax, and stock-based compensation.

Both are measured at the enacted tax rate expected to apply when they reverse, and are not discounted. A DTA is reduced by a valuation allowance if the company isn't likely to earn enough taxable income to use it. Permanent differences, such as non-deductible fines, never reverse and create no deferred taxes.

What is a valuation allowance, and what happens when a company releases one?

A valuation allowance reduces deferred tax assets for the portion the company is more likely than not (above 50%) unable to use, because it won't generate enough taxable income of the right kind, in the right jurisdictions, before the assets expire. Under US GAAP the DTAs are recorded in full and the allowance is netted against them. Recent cumulative losses are strong evidence that an allowance is needed.

Recording an allowance is a non-cash charge to income tax expense, so net income falls without any cash moving. Releasing it, typically after a company returns to sustained profitability, does the opposite: the deferred tax assets come back onto the balance sheet and the company records a one-time tax benefit, which can make net income spike, sometimes above pre-tax income.

For bankers, the key points are:

- Neither the charge nor the release changes cash taxes; the company's losses and deductions are still there either way. - A release is non-recurring: it should be removed when normalizing earnings or the effective tax rate. - The allowance is a signal of management's view of future taxable income, and the underlying tax attributes, such as NOLs, may still be worth something to a buyer.

A company has a $100 NOL ($25 DTA) and earns $200 of pre-tax income (25% tax). Walk me through the statements.

The NOL cuts cash taxes, not tax expense: net income is $150, but cash rises by $175.

1. Income statement: tax expense is 25% x $200 = $50, so net income is $150. The expense splits into $25 of current tax (on taxable income of $100 after using the NOL; the 80% limit isn't binding, since 80% of $200 is $160) and $25 of deferred tax expense from using up the deferred tax asset. 2. Cash flow statement: net income $150, plus the $25 of deferred tax expense (the decrease in the DTA is non-cash), so operating cash flow is $175. 3. Balance sheet: cash up $175, deferred tax asset down $25, so assets rise by $150; retained earnings rise by $150.

The benefit of the NOL was recognized in the past, when the loss created the deferred tax asset; using it now converts that asset into cash tax savings. (If the company had a full valuation allowance on the NOL, the allowance release would offset the deferred tax expense, so tax expense would be only $25.)

How would you value a company's NOLs?

An NOL is worth the present value of the taxes it will save, which is usually far less than the NOL balance times the tax rate. Three things drive it:

- Future taxable income: an NOL only has value if the company (or a buyer) will earn taxable income to offset. Under current US federal rules, post-2017 losses can be carried forward indefinitely but offset only 80% of taxable income each year, so usage is spread out. - Limits after an ownership change: under Section 382, if ownership changes by more than 50 percentage points over three years, as in most acquisitions, the annual usable amount is capped at roughly the equity value times the long-term tax-exempt rate, which can stretch usage over many years. - Discount rate: because the savings depend on uncertain future profits, bankers often discount them at a rate above WACC, closer to the cost of equity.

In a DCF, you either model NOL usage year by year in the tax line, or forecast taxes without it and add the present value of the NOL savings as a separate asset in the bridge to equity value; you must not do both. A large NOL balance with a valuation allowance and an ownership change can be worth very little.

A company has $100 of adjusted taxable income (EBITDA-based) and $40 of net interest expense (25% tax). How much interest can it deduct, and what happens to the rest?

It can deduct $30; the other $10 is carried forward.

Section 163(j) caps the deduction for net business interest at 30% of adjusted taxable income (measured on an EBITDA-like basis again from 2025): 30% x $100 = $30.

1. Taxable income: roughly $100 - $30 = $70 instead of $60 with full deductibility, so cash tax is $17.50 instead of $15: $2.50 more. 2. Carryforward: the disallowed $10 carries forward indefinitely and can be deducted in a later year with room under the cap. 3. Books: the carryforward is a deductible temporary difference, so the company records a $2.50 deferred tax asset if it expects to use it. Total tax expense is then unchanged and only the cash timing differs; if it doesn't expect to use it, a valuation allowance means the effective tax rate rises.

It matters most in leveraged buyouts: when leverage is highest, part of the interest tax shield is deferred or lost, so cash taxes in a buyout model must be calculated with the cap, not as the tax rate times pre-tax income.

A law raising the corporate tax rate from 21% to 28% is enacted. A company has $2,000 of taxable temporary differences. What happens to its statements?

The deferred tax liability is remeasured at the new rate in the period the law is enacted, creating a one-time, non-cash charge of $140.

1. Balance sheet: the DTL rises from 21% x $2,000 = $420 to 28% x $2,000 = $560, an increase of $140. 2. Income statement: the $140 increase is recorded as deferred tax expense in income from continuing operations, so net income falls by $140, all in the quarter of enactment. 3. Cash flow statement: no cash moves now; the deferred tax expense is added back. The extra tax is paid in later years, as the temporary differences reverse at the higher rate.

Deferred tax assets work the other way: a rate increase raises their value and produces a one-time benefit. Going forward, the higher rate also raises current tax on future profits, which is what actually reduces free cash flow and valuation. Bankers strip the one-time remeasurement out of normalized earnings.

A company issues $500 of 5-year notes at 96 with a 7% coupon and pays $5 of fees. Walk me through issuance and year one (25% tax; amortize straight-line).

The company owes $500 but receives only $475: $480 of proceeds (96% of face, an original issue discount of $20) less $5 of fees.

At issuance:

1. Income statement: no effect; the discount and fees aren't expensed upfront. 2. Cash flow statement: $475 of net debt proceeds in financing activities. 3. Balance sheet: cash up $475; debt recorded at $475, its face value less the unamortized discount and fees.

Year one: the $25 of discount and fees is amortized into interest expense, $5 a year over five years (straight-line here as an approximation of the effective interest method).

1. Income statement: interest expense of $40: $35 of cash coupon (7% x $500) plus $5 of amortization. Tax falls by $10, so net income falls by $30. 2. Cash flow statement: net income down $30, plus the $5 of non-cash amortization added back, so operating cash flow falls by $25 (the $35 coupon less $10 of tax saved). 3. Balance sheet: cash down $25; the debt's carrying amount rises by $5 to $480, accreting toward $500 by maturity; retained earnings down $30.

So the all-in cost of the debt is higher than the coupon, and interest expense exceeds cash interest every year. If the notes are repaid early, any unamortized discount and fees are written off as a loss on extinguishment.

A company buys back $100 of its bonds for $60 (25% tax). Walk me through the statements.

Retiring debt below its carrying amount produces a gain: here $40 (ignoring any unamortized issuance costs).

1. Income statement: a $40 gain on extinguishment of debt; the forgiven debt is generally taxable, so tax is $10 and net income rises by $30. 2. Cash flow statement: net income up $30, less the $40 non-cash gain, so operating cash flow is -$10 (the tax). The $60 paid to repurchase the bonds is a financing outflow. Cash falls by $70. 3. Balance sheet: cash down $70; debt down $100 and retained earnings up $30. Assets -$70 = liabilities -$100 + equity $30.

This usually happens when a company is distressed and its bonds trade well below par. The gain is real for shareholders, because the company owes $40 less, but it is non-recurring, so bankers exclude it from EBITDA and normalized earnings. Unamortized issuance costs or discounts reduce the carrying amount and therefore the gain; paying above par to retire debt early produces a loss instead.

$100 of convertible bonds convert into 5 shares when the stock trades at $30. What happens to the statements and to debt-to-equity?

The bonds are in the money: 5 shares for $100 is a conversion price of $20, below the $30 share price, so holders convert (5 shares are worth $150).

On conversion into shares:

1. Income statement: no gain or loss; under US GAAP (ASU 2020-06) the convertible is carried as a single liability at amortized cost, and its carrying amount simply moves into equity. Going forward, interest expense disappears. 2. Cash flow statement: no cash moves; it is a non-cash financing transaction, disclosed in the supplemental information. 3. Balance sheet: debt falls by $100 and common stock plus paid-in capital rise by $100 (assuming the carrying amount equals face). Total liabilities plus equity don't change.

Debt-to-equity falls on both counts: the numerator drops by $100 and the denominator rises by $100. The share count rises by 5, which is why diluted EPS already includes convertibles that are dilutive, using the if-converted method: add back the after-tax interest to net income and add the conversion shares to the denominator.

What is treasury stock, and what happens on the statements when a company buys back $50 of shares?

Treasury stock is the company's own shares that it has repurchased and holds rather than retires. It appears in shareholders' equity as a negative line, usually at cost, and the shares are excluded from shares outstanding and from EPS.

For a $50 buyback:

1. Income statement: no effect; buying back shares isn't an expense. EPS can rise, because the share count falls (net income may fall slightly if the cash would have earned interest). 2. Cash flow statement: $50 of share repurchases in financing activities, so cash falls by $50. 3. Balance sheet: cash down $50; treasury stock up $50 (a deduction from equity), so equity falls by $50.

If the company retires the shares instead, the cost is charged against common stock, additional paid-in capital and possibly retained earnings, with the same total effect on equity. Large buybacks at prices far above book value are how profitable companies end up with negative shareholders' equity.

Should you add back stock-based compensation when you value a company?

It depends on how dilution is treated, and the key is not to ignore SBC in both places.

SBC is a non-cash expense, so it is added back on the cash flow statement and most companies exclude it from adjusted EBITDA. But it is a real cost: employees are paid in shares instead of cash, so existing shareholders own less of the company, or the company spends cash on buybacks to offset the dilution.

The consistent approaches:

Treat it as a cash cost: keep SBC as an expense in EBITDA and free cash flow (don't add it back), and use today's diluted share count. This is the conservative and increasingly common view, especially for tech companies where SBC is large.

Add it back but count the dilution: exclude SBC from the cash flows, but include the shares from all future grants in the share count, which is hard to forecast reliably.

Adding SBC back to cash flow while using only the current share count overstates value, because it treats employee pay as free. When comparing companies on adjusted EBITDA, a banker checks whether SBC was added back and how large it is relative to revenue and operating income.

What is an underfunded pension, where does it show up, and how do bankers treat it?

A defined benefit pension is underfunded when the present value of the benefits employees have earned (the projected benefit obligation) exceeds the fair value of the plan's assets. The difference is the funded status, recorded on the balance sheet as a liability.

Where it shows up:

- Balance sheet: the net pension liability (or an asset if overfunded). - Income statement: pension cost, of which only the service cost sits in operating income; interest cost, expected return on assets and amortization sit below it. - Other comprehensive income: actuarial gains and losses, for example from changes in the discount rate, until they are amortized. - Cash flow statement: the company's contributions to the plan, which can differ a lot from the expense.

Bankers treat the deficit as a debt-like item: it is subtracted, net of the tax deduction the company gets when it funds it, in the bridge from enterprise value to equity value, and lenders and rating agencies often add it to leverage. They also look past reported pension income, which can appear simply because the assumed return on assets exceeds interest cost, to the funded status, the discount-rate sensitivity and the cash contributions the company will have to make.

A company is fined $100 by a regulator, payable $20 a year for five years (fines are not tax deductible). Walk me through the statements at the ruling and at the first payment.

Ignoring discounting, the whole loss is recognized at the ruling, and cash leaves as it is paid.

At the ruling:

1. Income statement: a $100 expense. Government fines aren't tax deductible, so there's no tax benefit, and net income falls by the full $100. 2. Cash flow statement: net income down $100, plus the $100 increase in the accrued liability (non-cash), so cash is unchanged. 3. Balance sheet: a $100 liability ($20 current, $80 noncurrent); retained earnings down $100.

At the first payment:

1. Income statement: no effect; the expense was already recorded. 2. Cash flow statement: the $20 payment reduces operating cash flow. 3. Balance sheet: cash down $20, liability down $20.

Two points drive the answer: a non-deductible fine has no tax shield, and the expense is recognized when the obligation arises, not as the fine is paid. In valuation, the unpaid $80 is a debt-like item, and the charge itself is excluded from normalized EBITDA.

When do you use fair value, the equity method or consolidation for an investment?

It depends on how much influence the investor has, usually indicated by its share of the voting rights:

- Below 20%, no significant influence: fair value. The stake is carried at fair value (or at adjusted cost if there is no market price), and the income statement shows dividends plus changes in fair value. - 20% to 50%, significant influence: equity method. One investment line on the balance sheet, and one line of income for the investor's share of the investee's net income; dividends received reduce the investment rather than counting as income. - Above 50%, or control by other means: consolidation. All of the subsidiary's assets, liabilities, revenue and expenses are combined line by line, with noncontrolling interest in equity and in net income for the share owned by others. Control can also come from contracts, as with variable interest entities.

The thresholds are presumptions, not rules: control and influence are judged on substance. The choice matters for valuation because consolidated EBITDA includes 100% of a partly owned subsidiary (so noncontrolling interest is added to enterprise value), while equity method income sits below EBITDA (so equity investments are valued separately and added to enterprise value in the bridge).

What are Level 1, 2 and 3 fair value measurements?

They are the three levels of the fair value hierarchy under ASC 820, ranked by how observable the inputs are:

- Level 1: quoted prices for identical assets in active markets, such as listed shares and Treasuries. The most reliable. - Level 2: observable inputs other than quoted prices for the identical asset: quotes for similar securities, market interest rates, yield curves. Typical for most corporate bonds and many derivatives. - Level 3: valuations relying on significant unobservable inputs, management's own assumptions, using models such as DCFs. Typical for private equity stakes, illiquid loans and complex instruments.

Companies disclose how much of their fair-value assets and liabilities sit in each level, with a roll-forward for Level 3. For bankers, a large or growing Level 3 balance means reported values and the gains behind them rest on judgment, which matters for banks, insurers, asset managers and any company with big private investments.

A company buys $100 of shares in another company as a passive investment; they rise to $120, then are sold (25% tax, taxed on sale). Walk me through both steps.

Under US GAAP, listed equity investments without significant influence are carried at fair value through net income, so the gain is recognized when the price rises, not when the shares are sold.

The shares rise to $120:

1. Income statement: a $20 unrealized gain. It isn't taxed until sale, so the company records $5 of deferred tax expense; net income rises by $15. 2. Cash flow statement: net income up $15, less the $20 non-cash gain, plus the $5 deferred tax expense. Cash is unchanged. 3. Balance sheet: the investment is up $20; a $5 deferred tax liability; retained earnings up $15.

The shares are sold at $120:

1. Income statement: no further gain, since the shares are already at $120. Tax expense is unchanged in total: $5 of current tax replaces the deferred tax. 2. Cash flow statement: $120 of proceeds in investing activities; operating activities show the $5 of tax paid (the deferred tax liability reverses). Cash rises by $115. 3. Balance sheet: cash up $115, investment down $120, deferred tax liability down $5.

Bankers strip these unrealized gains and losses out of earnings, because they say nothing about the operating business.

Two companies with $50 of revenue each combine and report $150, with no synergies. How is that possible?

Through consolidation. Suppose each company owns a 30% stake in a third company with $50 of revenue. On their own, neither controls it, so each accounts for its stake under the equity method: its share of the third company's profit appears as a single line below operating income, and none of its revenue is included.

Once the two combine, the merged company owns 60%, gains control, and must consolidate 100% of the third company: all of its revenue and expenses are now included line by line, with a 40% noncontrolling interest. Combined revenue is $50 + $50 + $50 = $150.

The deeper point is that reported revenue depends on control, not on economic ownership: the merged company owns 60% of the third business but reports all of its revenue and EBITDA. (The opposite also happens: sales between the combining companies are eliminated on consolidation, which can make combined revenue less than the sum of the parts.)

A company owns 80% of a subsidiary that earns $200. How does that show up on its statements?

Because it controls the subsidiary, the parent consolidates 100% of it and then attributes 20% to the outside shareholders.

1. Income statement: all of the subsidiary's revenue and expenses are included, so consolidated net income includes the full $200. Then $40 (20%) is shown as net income attributable to noncontrolling interest, leaving $160 attributable to the parent's shareholders, which is the figure used for EPS. 2. Cash flow statement: starts from consolidated net income, including the full $200; all of the subsidiary's cash flows are included. Dividends paid by the subsidiary to the minority holders appear in financing. 3. Balance sheet: 100% of the subsidiary's assets and liabilities are included. Noncontrolling interest within equity rises by the $40 share (less any dividends paid to the minority), and retained earnings rise by $160.

For valuation, consolidated EBITDA includes 100% of the subsidiary's earnings, so the noncontrolling interest must be added to enterprise value (or the minority's share of EBITDA removed) to keep the multiple consistent.

How does a stronger dollar affect the statements of a US company with European operations?

It lowers the reported dollar value of everything the European subsidiary earns and owns, even if nothing changed in euros.

1. Income statement: the subsidiary's revenue and expenses are translated at average rates for the period, so with a stronger dollar each euro of sales and profit translates into fewer dollars. Reported revenue growth falls (which is why companies show constant-currency growth). Any foreign-currency balances that must be remeasured can also create transaction gains or losses in net income. 2. Balance sheet: the subsidiary's assets and liabilities are translated at the closing rate, so its net assets shrink in dollars. The loss doesn't go through net income: it is recorded in other comprehensive income and accumulated in equity as the cumulative translation adjustment, until the subsidiary is sold. 3. Cash flow statement: cash held in euros is worth fewer dollars; the effect of exchange rates on cash is shown on its own line, after financing activities.

For bankers, the consequence is that reported growth, margins and leverage can move with currencies rather than with the business, so they look at constant-currency figures and check whether euro-denominated debt offsets the effect on net assets and leverage.

Walk me through how an acquisition is recorded under the acquisition method.

Under ASC 805, when a company obtains control of a business, it follows four steps:

1. Identify the acquirer: the entity that obtains control, which in a share-for-share deal isn't always the legal buyer. 2. Determine the acquisition date: when control passes, usually the closing date. 3. Recognize and measure the target's identifiable assets and liabilities at fair value, including intangibles the target never recorded itself (customer relationships, technology, trade names), plus any noncontrolling interest. Deferred taxes are recorded on the differences between the new book values and the tax bases. 4. Recognize goodwill: the consideration transferred (cash, shares at fair value, contingent consideration), plus the fair value of any noncontrolling interest and previously held stake, less the fair value of the identifiable net assets. If that figure is negative, a bargain purchase gain.

Deal costs such as advisory fees are expensed, not added to the price. The allocation can be adjusted for up to a year (the measurement period) as information comes in. Afterwards, the write-ups flow through earnings as extra depreciation and amortization, and goodwill is tested for impairment rather than amortized.

How is a target's deferred revenue treated after an acquisition?

Under current US GAAP, it carries over at roughly the target's own book amount, and the acquirer recognizes it as revenue as the obligations are fulfilled, just as the target would have.

That's the result of ASU 2021-08, which requires acquirers to measure contract liabilities (deferred revenue) under the revenue standard, ASC 606, rather than at fair value. Before it, acquirers usually wrote deferred revenue down to the cost of fulfilling the obligation plus a margin. That deferred revenue haircut meant revenue the target had already been paid for never appeared in the acquirer's income statement, so post-deal revenue and margins dipped for a year or so, and acquirers added the lost revenue back in their non-GAAP figures.

It matters most for software and subscription targets with large deferred revenue balances. When looking at older deals or historical acquirer results, bankers check whether a haircut depressed reported revenue in the first year after closing.

A buyer pays $160 for 80% of a target whose identifiable net assets are worth $150; the NCI is worth $40. What is goodwill under US GAAP, and under the IFRS option?

Goodwill is $50 under US GAAP and $40 under the IFRS proportionate option.

US GAAP (full goodwill): noncontrolling interest is measured at fair value, so goodwill covers 100% of the business:

$160 + $40 - $150 = $50.

IFRS proportionate option: IFRS 3 lets the buyer choose, deal by deal, to measure NCI at its share of the identifiable net assets: 20% x $150 = $30. Goodwill then reflects only the buyer's share:

$160 + $30 - $150 = $40.

The difference, $10, is the minority's share of goodwill, which the proportionate method simply doesn't record. It lowers both goodwill and NCI on the balance sheet, and any future goodwill impairment is smaller, so goodwill and equity figures aren't directly comparable between a US company and an IFRS company that uses the option.

Walk me through a purchase price allocation and the intangibles it usually identifies.

A purchase price allocation (PPA) splits the price paid for a business across the fair values of everything acquired, with goodwill as the residual:

1. Start from the price and the book value: the equity purchase price against the target's book equity; the gap is what has to be allocated. 2. Revalue tangible assets and liabilities: inventory written up to roughly its selling price less costs to sell, PP&E to fair value, debt to fair value, and leases, pensions and deferred revenue under their own rules. 3. Identify and value intangible assets the target may never have recorded: customer relationships (usually valued with the multi-period excess earnings method), developed technology and trade names (often with relief-from-royalty), plus order backlog, licenses and non-compete agreements. Each gets a useful life, which sets its amortization. 4. Record deferred taxes and goodwill: in a stock deal, the write-ups create deferred tax liabilities because the tax bases don't change. Goodwill is the price less the fair value of the identifiable net assets, after those deferred taxes.

It matters to bankers because it drives post-deal earnings: inventory step-ups hit gross margin in the first months, write-ups add depreciation and amortization for years, and the goodwill balance is exposed to future impairment.

Why do asset write-ups create a deferred tax liability in a stock deal but not in an asset deal, and why might a buyer write down the target's deferred tax assets?

It comes down to the tax basis of the assets.

Stock deal: the buyer acquires the target's shares, so the target keeps its old tax bases. For the books, the assets are written up to fair value, so book values now exceed tax values. The extra book depreciation and amortization won't be deductible, so future taxes will be higher than book taxes suggest. That gap is recorded as a deferred tax liability equal to the write-up times the tax rate, and it increases goodwill. It unwinds as the written-up assets are depreciated.

Asset deal (or a stock deal with a 338(h)(10) or 336(e) election): the buyer gets a stepped-up tax basis equal to fair value, so book and tax values match and no DTL arises. The extra depreciation, and goodwill amortization over 15 years, are deductible, which is valuable to the buyer.

The target's deferred tax assets come along in a stock deal, but the buyer has to reassess them. NOLs are capped by Section 382 after the ownership change, and some credits or losses may expire before they can be used, so the buyer records a valuation allowance (or writes the DTA down) for the portion it doesn't expect to realize. That reduces the identifiable net assets and increases goodwill.

A buyer pays $500 for a target with $200 of book equity and writes assets up by $100 in a stock deal (25% tax). What is goodwill?

Goodwill is $225.

1. Write-ups: the identifiable assets are written up by $100 to fair value. 2. Deferred tax liability: in a stock deal the tax bases don't change, so the write-up creates a DTL of 25% x $100 = $25. 3. Fair value of identifiable net assets: $200 + $100 - $25 = $275. 4. Goodwill: $500 - $275 = $225.

(This assumes the target has no existing goodwill; any would be written off and replaced.) Note that the DTL increases goodwill dollar for dollar: without it, goodwill would be $200. In an asset deal or with a 338(h)(10) election, the tax bases are stepped up too, so no DTL arises and goodwill is lower, but becomes tax deductible.

A buyer pays $100 in stock, and the next day the market says the target is worth $50. What happens on the buyer's statements?

At closing, nothing reflects the market's view: the acquisition is recorded at the fair value of the consideration, the $100 of shares at the closing-date price. The buyer's equity rises by $100, the target's identifiable net assets come in at fair value, and the excess over them is recorded as goodwill. The buyer's share price may fall immediately, but the balance sheet doesn't record market capitalization.

The overpayment shows up later, if at all, through a goodwill impairment: when the reporting unit that holds the target is tested (at least annually, or sooner if there is a triggering event such as a sustained share price fall), and its fair value is below its carrying amount, the company writes goodwill down. That is a non-cash charge to earnings, usually non-deductible, with no effect on cash.

So accounting captures overpayment with a lag; the market captures it at once. A sharp fall in the buyer's share price after a deal is often the earliest signal of a future impairment.

What is the difference between a stock deal and an asset deal, and which does each side prefer?

In a stock deal, the buyer acquires the target's shares, so it takes the whole legal entity: all assets and all liabilities, including unknown and contingent ones, and the target's tax attributes such as NOLs (subject to limits). For tax, the assets keep their old carryover basis. In an asset deal, the buyer buys selected assets and assumes only the liabilities it agrees to, and gets a stepped-up tax basis equal to the price paid.

Who prefers what:

Buyers usually prefer asset deals: the step-up creates extra tax deductions (depreciation, and amortization of tax goodwill over 15 years), and they can leave unwanted liabilities behind.

Sellers usually prefer stock deals: a C corporation selling assets pays corporate tax on the gain, and its shareholders are taxed again when the proceeds are distributed (double taxation), while a stock sale is taxed once at the shareholder level. Stock deals are also simpler, since contracts and permits stay with the entity.

On the books, both are recorded under the acquisition method at fair value; the difference is that a stock deal creates deferred tax liabilities on the write-ups (book values above tax bases) while an asset deal doesn't. Elections such as 338(h)(10) can give an asset-deal tax result to a stock purchase, and the price is often adjusted to share the value of the step-up.

What is a Section 338(h)(10) election, and why use one?

A 338(h)(10) election lets a stock purchase be treated as an asset purchase for tax, while legally it remains a purchase of shares. For tax, the target is deemed to sell all its assets at the acquisition date and then liquidate into its seller.

Why it is used:

The buyer gets a stepped-up tax basis in the assets equal to the price paid, so it gets larger depreciation and amortization deductions (including 15-year amortization of tax goodwill), which raises after-tax cash flow.

The seller is taxed only once, on the deemed asset sale, rather than on both an asset sale and a distribution, and the deal keeps the legal simplicity of a stock purchase: contracts and licenses stay with the entity.

Conditions: the buyer must be a corporation acquiring at least 80% of the target's stock within 12 months (a qualified stock purchase), the target must be an S corporation or a subsidiary of a consolidated or affiliated group (not a standalone C corporation owned by individuals or the public), and buyer and seller must elect jointly.

Because the seller may pay more tax than on a plain share sale (for example, ordinary income on recaptured depreciation), buyers often pay a higher price to compensate. The election makes sense when the present value of the buyer's tax savings exceeds the seller's extra tax. On the books, no deferred tax liability arises on the write-ups, since book and tax bases match.

A buyer acquires a company with $100 of NOLs for an equity value of $500; the long-term tax-exempt rate is 4%. How fast can the NOLs be used?

About $20 a year, so the $100 of NOLs takes 5 years to use.

The acquisition is an ownership change (more than 50 percentage points over three years), so Section 382 caps how much of the pre-change losses can be used each year:

$\text{Annual limit} = \text{Equity value of the loss company before the change} \times \text{Long-term tax-exempt rate}$

$500 x 4% = $20 a year, and $100 / $20 = 5 years (assuming the combined company has enough taxable income each year).

At a 25% tax rate, the NOLs save $5 of tax a year, $25 in total, but spread over five years, so their present value is lower than $25. The smaller the target relative to its losses, the slower the usage and the less the NOLs are worth, which is why a large NOL balance in a small, cheap target is often worth far less than it looks. Any unused annual limit carries forward to later years.

How are advisory fees and financing fees treated in an acquisition?

They are treated differently because they pay for different things.

- Advisory and other deal fees (bankers, lawyers, accountants, valuers) are expensed as incurred under ASC 805. They aren't part of the price, so they don't increase goodwill. They hit operating expenses, usually around closing, and the cash is an operating outflow. For tax, most costs that facilitate the deal have to be capitalized rather than deducted, with a safe harbor allowing 70% of success-based fees to be deducted. - Debt financing fees (underwriting, arrangement fees, original issue discount) are deducted from the carrying amount of the debt and amortized into interest expense over its life. Revolver arrangement fees are usually carried as an asset and spread over the facility's term. - Equity issuance costs reduce the proceeds recorded in additional paid-in capital.

In a merger model, deal fees reduce cash (or are funded) and reduce equity as a one-time expense, while financing fees are capitalized and add a small amount of non-cash interest each year. Bankers exclude both from normalized earnings and from the pro forma run rate.

An earnout is valued at $20 at closing and $30 a year later. What happens to the statements?

The earnout's fair value at closing is part of the purchase price, and later changes go through earnings, not goodwill.

At closing: a $20 contingent consideration liability is recorded and included in the consideration transferred, so it is part of goodwill. No cash moves.

A year later, the target is performing better, so the liability is remeasured to $30:

1. Income statement: a $10 expense (a loss on remeasurement of contingent consideration). It generally isn't deductible until paid, so with no tax benefit, net income falls by $10. 2. Cash flow statement: net income down $10, add back the $10 non-cash remeasurement, so cash is unchanged. 3. Balance sheet: the liability rises by $10 to $30; retained earnings fall by $10. Goodwill doesn't change.

The counterintuitive result is that a better-performing acquisition produces a charge, and a worse one a gain as the liability falls. Bankers strip these remeasurements out of adjusted earnings. When the earnout is paid, the portion up to the acquisition-date value is typically financing and any excess operating.

What adjustments go into pro forma financial statements after an acquisition?

Pro forma statements show the combined company as if the deal had already happened: the balance sheet as if it closed at the latest balance sheet date, and the income statement as if it closed at the start of the fiscal year. The adjustments reflect the deal itself:

- Purchase accounting: the target's assets and liabilities at fair value, new intangibles and goodwill, and the extra depreciation, amortization and inventory step-up that follow. - Financing: new debt and its interest expense (including amortized fees), shares issued, cash used, and the interest income lost on that cash. - Debt refinanced or repaid, with the related interest removed. - Tax effects of each adjustment, at the applicable rate. - Transaction costs, reflected in the pro forma balance sheet and generally shown as non-recurring.

For SEC filings (Article 11 of Regulation S-X), these are transaction accounting adjustments; companies may also show management's adjustments, such as expected synergies, separately and only in the notes. Bankers build the same logic in merger models: combine the two companies, layer on the purchase accounting and financing, and strip out one-offs to get a pro forma run-rate for EPS, leverage and covenants.

A company trades at 2x EV/revenue and 10x EV/EBITDA. What is its EBITDA margin?

The EBITDA margin is 20%.

Both multiples share the same enterprise value, so dividing one by the other cancels it:

$\text{EBITDA margin} = \frac{\text{EBITDA}}{\text{Revenue}} = \frac{\text{EV / Revenue}}{\text{EV / EBITDA}} = \frac{2}{10}$

Check with numbers: if EV is $1,000, revenue is $500 and EBITDA is $100, so the margin is $100 / $500 = 20%.

The same logic explains why higher-margin companies tend to trade at higher revenue multiples: at a given EV/EBITDA multiple, EV/revenue is simply the EBITDA margin times that multiple.

What does ROIC measure, and how does it differ from ROE?

ROIC (return on invested capital) measures how much after-tax operating profit a business earns on all the capital invested in it, from lenders and shareholders alike:

$\text{ROIC} = \frac{\text{NOPAT}}{\text{Invested capital}} = \frac{\text{EBIT} \times (1 - t)}{\text{Debt} + \text{Equity} - \text{Excess cash}}$

(invested capital can equally be built from the asset side: net working capital plus net PP&E, goodwill and other operating assets).

ROE measures net income over shareholders' equity: the return to shareholders only, after interest.

The key difference is leverage. ROIC is capital-structure neutral, so it shows the quality of the business itself. ROE can be pushed up by borrowing or buybacks without any improvement in the business, and becomes meaningless when equity is tiny or negative. ROE is still the right measure for banks and insurers, where debt is part of operations.

For valuation, the comparison that matters is ROIC against WACC: a business creates value only when it earns more on its capital than that capital costs, and growth adds value only when ROIC exceeds WACC. Choices such as including goodwill (to judge acquisitions) or excluding it (to judge the operations) change the result, so bankers state the definition they use.

A company has a 5% net margin, 1.5x asset turnover and 2x leverage. What is its ROE?

ROE is 15%.

The DuPont identity breaks return on equity into three drivers:

$\text{ROE} = \frac{\text{Net income}}{\text{Revenue}} \times \frac{\text{Revenue}}{\text{Assets}} \times \frac{\text{Assets}}{\text{Equity}}$

5% x 1.5 x 2 = 15%.

The value of the breakdown is that it shows where the return comes from: profitability (margin), efficiency (turnover) or financial leverage. Two companies with the same 15% ROE can be very different: a retailer with thin margins and high turnover, or a lender with modest returns on assets amplified by leverage. Rising ROE driven only by more leverage or buybacks is lower quality than ROE driven by better margins or turnover.

What is the difference between the current ratio and the quick ratio?

Both measure whether a company can meet its short-term obligations with its short-term assets.

Current ratio = current assets / current liabilities. It includes everything due to turn into cash within a year, including inventory and prepaid expenses.

Quick ratio (acid test) = (cash + short-term investments + receivables) / current liabilities. It excludes inventory and prepaids, which may take time to convert or can't be converted at full value.

The quick ratio is the stricter test, useful when inventory is slow-moving or hard to sell. Neither should be read mechanically: a low ratio can be perfectly healthy for a business that collects from customers before paying suppliers, such as a grocer or a subscription company, while a high ratio can hide stale receivables or inventory. Lenders care more about cash flow, undrawn credit lines and the debt maturity profile than about these ratios alone.

Leverage is 4x EBITDA and interest coverage is 5x. What is the interest rate on the debt?

The interest rate is 5%.

Pick an EBITDA figure, say $100:

1. Debt: 4x EBITDA = $400. 2. Interest: coverage of 5x means EBITDA / interest = 5, so interest = $100 / 5 = $20. 3. Rate: $20 / $400 = 5%.

The general shortcut is rate = 1 / (leverage x coverage) = 1 / (4 x 5) = 5%. It assumes coverage is measured on EBITDA and leverage on total debt, with interest on the full debt balance; if coverage were EBIT-based, the answer would need D&A.

Is free cash flow the best measure of a company's ability to service debt?

It is the best single measure, but it needs to be read carefully, and lenders look at several metrics together.

Free cash flow (operating cash flow less capex) captures what EBITDA ignores: capex, working capital, taxes and, under US GAAP, interest paid. That's why debt capacity is ultimately a cash question. But:

- It is after interest, so for debt service you either add interest back (cash available for debt service) or compare it with principal due, not total debt service. - It can be distorted: a one-time working capital release, deferred capex or a tax refund can inflate a single year. Bankers normalize it and look at several years. - It ignores maturities and liquidity: a company with healthy free cash flow can still default on a large bullet maturity it can't refinance, so lenders also look at the maturity profile, cash and undrawn revolver.

In practice, credit work uses EBITDA-based leverage and coverage (because covenants are written on them), plus fixed charge coverage, free cash flow to debt and a liquidity runway, with free cash flow as the reality check.

What is a quality of earnings report, and what does it adjust?

A quality of earnings (QoE) report is a diligence report, usually by an accounting firm, that tests whether a target's earnings are accurate, sustainable and backed by cash. It is not an audit: a company can have a clean audit opinion and still have adjusted EBITDA well below what management presents.

It typically covers:

- The EBITDA bridge: from reported to adjusted EBITDA, testing each management add-back and adding the diligence team's own: removing non-recurring items, normalizing owner and related-party costs, correcting accounting errors or aggressive policies, and judging pro forma and run-rate adjustments. - Proof of cash: reconciling reported revenue and profit to bank statements and cash flow. - Net working capital: the deal definition of working capital and the peg. - Net debt and debt-like items: everything that should reduce the price in a cash-free, debt-free deal. - Capex, split between maintenance and growth, and often payroll and tax exposures.

Its findings feed straight into the deal: the buyer re-bases its multiple on the lower adjusted EBITDA, negotiates specific indemnities or escrows for identified exposures, and the report supports the lenders' financing and the reps and warranties insurer.

Which debt-like items do you look for in due diligence?

Deals are usually priced cash-free, debt-free, so anything that will require a cash payment the buyer didn't price into enterprise value should reduce the equity price, beyond the obvious borrowings:

- Lease obligations: finance leases, and depending on the deal, operating leases. - Employee items: accrued but unpaid bonuses, severance, deferred compensation, underfunded pensions and other long-term benefits. - Taxes: income taxes owed for periods before closing, and identified tax exposures. - Deal and prior-deal items: unpaid transaction fees, earnouts or deferred consideration from earlier acquisitions. - Operating items with a financing character: customer deposits, deferred revenue where the cost to deliver is material, deferred capex the business has skipped, factored receivables or supplier finance balances. - Litigation and environmental accruals, and asset retirement obligations.

Each is negotiated, and the same item can't be counted both as debt-like and in working capital. On the cash side, trapped cash, customer deposits held on others' behalf and minimum operating cash aren't treated as excess cash.

How does a working capital peg work in an acquisition?

The purchase price assumes the business is delivered with a normal level of working capital, the peg, usually a trailing twelve-month average of monthly balances to smooth out seasonality. At closing, the price moves dollar for dollar with the difference between the working capital actually delivered and the peg: below the peg, the buyer pays less; above it, the buyer pays more.

The point is to stop the seller from extracting cash before closing. A seller that collects receivables aggressively or delays supplier payments keeps the extra cash (in a cash-free, debt-free deal it belongs to the seller), but delivers a business that needs more cash afterwards, so the working capital delivered falls below the peg and the price falls by the shortfall.

Two details matter in practice. The definition of deal working capital usually excludes cash, debt, income taxes and transaction items, which are handled elsewhere. And the closing statement must use the same accounting policies as the peg calculation; disputes are usually settled by an independent accountant.

What is the difference between normalization and pro forma adjustments to EBITDA?

Normalization adjustments remove the effects of things that already happened but don't reflect the ongoing business, so that historical EBITDA shows what the business earned under normal conditions: one-off litigation, a restructuring, a gain on an asset sale, above-market owner salaries or related-party rents, accounting errors or policy changes.

Pro forma (and run-rate) adjustments add the effect of changes that haven't fully shown up in the historical figures: the full-year earnings of an acquisition made mid-year, cost savings from initiatives under way, a price increase in effect for only part of the period, or synergies the buyer expects.

The difference matters because the evidence differs. Normalizations can be tested against what actually happened; pro forma adjustments depend on assumptions about the future and execution. Diligence providers usually accept pro forma adjustments for actions already completed and documented, and reject or discount those that rely on future steps. Projected savings often fail to materialize in full, so bankers treat run-rate savings and synergies as the weakest part of any adjusted figure.

EBITDA grew 20% but operating cash flow fell. What could explain it?

The gap is somewhere between EBITDA and operating cash flow, so I'd look at what sits between them:

- Working capital: receivables or inventory growing faster than sales is the most common cause. It can be benign (fast growth, a big sale at period end, a seasonal build) or a warning (looser credit terms, customers paying late, unsold stock, revenue recognized ahead of delivery). - Cash items below EBITDA: higher cash interest after new borrowing, higher cash taxes, or restructuring and litigation payments excluded from adjusted EBITDA but paid in cash. - Non-cash gains in EBITDA: gains on asset sales, favorable changes in estimates, reserve releases or income from equity investees that don't bring cash. - Capitalization and classification: costs moved out of operating expenses into capex or capitalized software lift EBITDA without changing cash; conversely, a company that stopped selling receivables or using supplier finance loses a cash benefit.

To tell which, I'd bridge EBITDA to operating cash flow line by line, track DSO, DIO and DPO over several quarters, check reserves against the items they cover, and see whether the gap persists. A one-year gap with a clear working capital reason is common; earnings persistently above cash flow is a classic red flag.

The same "one-time" add-backs appear every year. How do you challenge them?

If they recur, they are a cost of running the business, and adjusted EBITDA overstates earnings by treating them as exceptional.

How to challenge them:

1. Look at the history: line up the add-backs over three to five years. Restructuring every year, "integration costs" from a steady stream of acquisitions, or litigation that keeps coming back under different names means the costs are recurring. 2. Ask what drives them: for some businesses a cost that looks unusual is normal, such as lawsuits for a pharma company or store closures for a retailer. 3. Normalize rather than exclude: include an average annual level of the cost in EBITDA instead of adding all of it back. 4. Check consistency: whether the company only adds back charges and never deducts one-off gains, and whether the definition of adjusted EBITDA keeps changing.

The consequence is direct: every dollar wrongly added back is multiplied by the valuation multiple and by the leverage the business is assumed to carry, so recurring "one-time" costs are one of the first things a buyer's diligence team removes.

Inventory days rose sharply and management calls it strategic. What would you check?

Whether the build is a real decision with a clear purpose, or a sign of slowing sales and future write-downs.

What I'd check:

- The stated reason: pre-buying ahead of price increases or tariffs, building stock for a launch or season, or securing supply. Each should show up in specific products and should unwind on a predictable timetable. - Composition and aging: which products and locations hold the extra inventory, and how much is old or slow-moving. Inventory concentrated in a few aging lines suggests unsold product. - Sales trends and orders: inventory growing faster than cost of sales while demand is flat is the classic warning sign. - Reserves: whether the inventory reserve kept pace with older stock, or fell as a share of inventory, which would flatter margins. - Cash and margins: the cash tied up, and whether gross margin was helped by absorbing more fixed factory overhead into a larger inventory.

If the build doesn't reverse, it points to write-downs, lower margins and weaker cash flow ahead, so in diligence it feeds both the working capital peg and the forecast.

Why do companies report non-GAAP figures, and which adjusted EBITDA add-backs are typical?

Companies report non-GAAP figures, such as adjusted EBITDA and adjusted EPS, to show what they consider their underlying, recurring performance, stripping out items that make one period hard to compare with another. Analysts, lenders and acquirers rely on them, and credit agreements are written on them. The SEC requires public companies to reconcile each one to the nearest GAAP measure and not to give it more prominence.

Typical add-backs to adjusted EBITDA:

- Non-recurring items: restructuring charges, litigation settlements, gains or losses on asset sales, impairments. - Non-cash items: stock-based compensation, the most debated add-back. - Deal-related items: transaction costs, integration expenses, purchase accounting effects such as inventory step-ups. - Other one-offs: costs of a discontinued product line, unusual legal or regulatory expenses.

The test for any add-back is evidence and recurrence: a cost that shows up every year under different names isn't one-time, stock-based compensation is a real cost paid in shares, and projected savings or synergies not yet achieved are the most fragile adjustments. Bankers compare reconciliations over several years and check whether the list of adjustments keeps growing.

Reading a 10-K, which footnotes would you read first, and why?

I'd start with the notes that change the numbers in a model, then the ones that hold the risks:

1. Accounting policies: how the company recognizes revenue, capitalizes costs and sets useful lives, which tells me how comparable its figures are. 2. Revenue: disaggregation by product and region, deferred revenue and remaining performance obligations. 3. Debt and leases: maturities, rates, covenants and lease liabilities, for net debt and leverage. 4. Income taxes: the rate reconciliation, deferred tax balances, NOLs and cash taxes paid. 5. Stock compensation, EPS and acquisitions: dilution, the diluted share count and the purchase price allocations of recent deals. 6. Segments: revenue, profit and assets by business, which often reveals the real drivers. 7. Commitments and contingencies, and subsequent events: litigation, guarantees, purchase obligations and anything that happened after the year end.

The auditor's report, especially the critical audit matters, is a useful map of where the numbers depend most on judgment. The notes are where most adjustments to reported EBITDA, net debt and the share count come from.

How would you adjust a European IFRS company's EBITDA to compare it with US peers?

Put both on the same basis, usually US GAAP, adjusting only the items that are material for that company:

1. Leases (the big one): under IFRS 16, lease costs sit below EBITDA as depreciation and interest, so IFRS EBITDA is higher. Either deduct an estimate of the lease cost (roughly the lease payments) from the IFRS company's EBITDA, or add lease liabilities to the US peers' debt and their lease costs back to EBITDA, and treat EV and leverage consistently. 2. Development costs: IFRS capitalizes development spending once criteria are met; deduct the amount capitalized in the year from EBITDA, since a US company would have expensed it. 3. Inventory and impairments: IFRS bans LIFO and allows impairment reversals; adjust if a peer uses LIFO or the IFRS company booked a reversal. 4. Cash flow classification: check where interest paid sits (operating or financing, and in financing for most companies under IFRS 18 from 2027) before comparing operating cash flow or cash conversion.

Then check each company's own definition of EBITDA and its non-GAAP adjustments, and make sure the multiples use enterprise values built the same way, especially for leases.

You find that last year's depreciation was overstated by $100 (25% tax, tax depreciation unaffected). How is it corrected, and what changes?

It is a correction of an error, so under ASC 250 it is fixed in the period it occurred, not by booking a $100 gain this year.

How: if the error is material to last year's statements, the company restates and reissues them (a Big R restatement, with an 8-K saying the old statements can't be relied on). If it is immaterial to last year but would distort this year if corrected in one go, it revises the comparative figures in the current filing (a little r revision).

What changes in the restated figures:

1. Last year's income statement: depreciation falls by $100, so pre-tax income rises by $100. Tax depreciation didn't change, so current tax is unaffected; deferred tax expense rises by $25. Net income rises by $75. 2. Balance sheet: net PP&E is $100 higher (accumulated depreciation lower); deferred taxes move by $25 against the company (a higher DTL or lower DTA); retained earnings are $75 higher, which also raises this year's opening retained earnings. 3. Cash flow statement: no change to cash; within operating activities, the higher net income is offset by the lower depreciation add-back and higher deferred tax.

The bigger issue for a banker is what the error says about controls: restatements often come with material weaknesses, management or auditor changes and, under the SEC's clawback rules, recovery of executive pay. They raise questions about how reliable the rest of the numbers are.

How would a software company's financial statements differ from a grocery chain's?

They reflect very different economics.

- Income statement: the software company has very high gross margins (hosting and support are its main direct costs) but heavy spending on R&D, sales and marketing, and often large stock-based compensation, so operating margins can be thin or negative while it grows. The grocer has thin gross margins and thin operating margins, earning its return on volume. - Balance sheet: the software company has few physical assets, its main liability is often deferred revenue from upfront billing, and acquired intangibles and goodwill can be large. The grocer carries inventory, store property and large lease liabilities, with payables that often exceed inventory. - Cash flow: both can have negative working capital: the software company because customers prepay, the grocer because it sells stock before paying suppliers. The grocer's capex goes into stores and distribution; the software company's into capitalized software and data centers.

So bankers use different metrics: for software, ARR, net revenue retention, billings, and EBITDA with careful treatment of SBC; for grocers, same-store sales, inventory turnover and EBITDAR, which adjusts for rent.

What are the main parts of a bank's balance sheet, and how do loan loss provisions flow through its statements?

For a bank, the balance sheet is the business:

- Assets: loans (net of the allowance for credit losses), securities portfolios, cash and reserves at the central bank, and trading assets. - Liabilities: deposits (its main source of funding), short-term borrowings and long-term debt. - Equity: a thin layer relative to assets, closely watched by regulators through capital ratios.

Loan loss provisions: under the CECL model, a bank reserves for losses expected over a loan's whole life as soon as it makes the loan. The provision for credit losses is the income statement charge that tops up the allowance: it equals net charge-offs in the period plus any change in the allowance. It reduces pre-tax income but uses no cash, so it is added back on the cash flow statement. When a specific loan is written off, both the loan and the allowance fall, with no income statement effect.

So a rising provision can mean losses are rising, or that the bank is building reserves for the future, which is why analysts split it into net charge-offs and reserve build.

How does an increase in net income affect a bank's CET1 ratio?

It raises it, as long as the profit isn't paid out.

The CET1 ratio is common equity tier 1 capital divided by risk-weighted assets. CET1 capital is broadly common equity (including retained earnings) less deductions such as goodwill, intangibles and certain deferred tax assets. Net income adds to retained earnings, so it increases CET1 capital; with risk-weighted assets unchanged, the ratio rises.

What offsets it: dividends and buybacks reduce retained earnings and capital, and loan growth increases risk-weighted assets. So retained profit is the main way banks build capital organically, and the CET1 ratio, against the regulatory minimum plus buffers, decides how much a bank can grow or return to shareholders. That's why bank valuation focuses on returns on tangible equity and capital generation rather than EBITDA.

What is an insurer's combined ratio, and what does it tell you?

The combined ratio measures whether an insurer makes money on its underwriting, before investment income:

$\text{Combined ratio} = \text{Loss ratio} + \text{Expense ratio}$

The loss ratio is claims and claim adjustment expenses divided by earned premiums; the expense ratio is underwriting and administrative expenses divided by premiums. Below 100% means an underwriting profit; above 100% an underwriting loss.

An insurer can still be profitable with a combined ratio slightly above 100%, because it also earns investment income on the float, the premiums it holds between collecting them and paying claims, which is why long-tail lines with slow claims can tolerate higher ratios. Bankers read it alongside reserve development (whether past claims reserves proved too low or too high, since reserve releases flatter the current ratio), catastrophe losses, and return on equity and book value, the main valuation anchors for insurers.

What is EBITDAX, and why do energy bankers use it?

EBITDAX is EBITDA before exploration expense: earnings before interest, taxes, depreciation, depletion and amortization, and exploration costs.

Oil and gas producers can account for exploration under two methods. Under successful efforts, the cost of unsuccessful exploratory wells (dry holes) and geological and geophysical work is expensed, reducing EBITDA. Under full cost, those costs are capitalized into the asset base and depleted over time, so they never hit EBITDA directly. Two producers with identical operations can therefore report very different EBITDA depending on the method and on a single year's exploration results.

Adding exploration expense back removes that difference, so EV/EBITDAX compares producers on their cash-generating operations. It is the standard multiple for E&P companies, alongside reserve-based measures such as EV per barrel of proved reserves, production and PV-10. Credit agreements for E&P companies are also often written on EBITDAX.

A producer spends $100 on a successful exploratory well and $100 on an exploratory dry hole. Walk me through the statements under successful efforts and under full cost (25% tax, taxes follow book).

The methods treat the dry hole differently; the successful well is capitalized under both.

Successful efforts (only costs that find reserves are capitalized):

1. Income statement: the $100 dry hole is expensed as exploration expense; tax falls by $25; net income falls by $75. 2. Cash flow statement: net income down $75, add back the $100 dry hole cost (the cash for both wells is shown as capex), so operating cash flow is +$25; investing shows -$200. Cash falls by $175. 3. Balance sheet: PP&E up $100 (the successful well), cash down $175, so assets fall by $75; retained earnings fall by $75.

Full cost (all exploration costs go into a cost pool):

1. Income statement: no effect now; both wells are capitalized and depleted later as reserves are produced. 2. Cash flow statement: -$200 of capex in investing; cash falls by $200. 3. Balance sheet: PP&E up $200, cash down $200.

Full cost shows higher earnings and assets today and higher depletion later; successful efforts is more conservative. Because identical companies can report different EBITDA, energy bankers compare them on EBITDAX, which adds exploration expense back.

A REIT has net income of $100, real estate depreciation of $60, a $20 gain on a property sale and $15 of recurring capex. What are FFO and AFFO, and why add back depreciation?

FFO is $140 and AFFO is $125.

FFO (funds from operations): net income plus real estate depreciation, less gains on property sales: $100 + $60 - $20 = $140.

AFFO (adjusted FFO): FFO less recurring capital spending needed to maintain the properties: $140 - $15 = $125. In practice AFFO also removes non-cash items such as straight-line rent and adds back non-cash compensation, and each REIT defines it slightly differently.

Why add back depreciation: GAAP depreciates buildings as if they lose value every year, but well-maintained real estate often holds or gains value, so depreciation makes a REIT's net income understate its recurring earning power. Gains on sales are removed because they are one-off and depend on when properties are sold.

REITs are therefore valued on price to FFO and price to AFFO rather than P/E, and dividend coverage is judged against AFFO, the closest measure to cash available for distribution.

A SaaS company reports $500 of revenue and deferred revenue rises from $200 to $260. What are billings, and why do investors watch them?

Billings are $560.

$\text{Billings} = \text{Revenue} + \Delta\text{Deferred revenue}$

$500 + ($260 - $200) = $560.

Subscription revenue is recognized over the contract term, so it lags what the company actually signs and invoices. Billings approximate what was invoiced in the period, including amounts that will be recognized as revenue later, so they can signal growth before it reaches revenue, and they track cash collection more closely.

They are noisy, though: they rise when customers move from monthly to annual or multi-year invoicing, and acquired deferred revenue adds to them without any new sales. So investors use billings as a cross-check alongside remaining performance obligations (contracted revenue not yet recognized) and annual recurring revenue, not as a substitute.

How does a company account for upfront and milestone payments when it licenses a drug candidate?

It depends on which side of the license the company is on, and on the drug's stage.

The licensee (paying): an upfront payment and development milestones for a drug not yet approved are usually expensed immediately as acquired R&D, because the asset has no alternative future use. Milestones paid after regulatory approval are generally capitalized as an intangible asset and amortized. Royalties are expensed as sales occur.

The licensor (receiving): an upfront payment for a distinct license is usually revenue when the license is granted; if the license can't be separated from ongoing research services, it is recognized as those services are performed. Milestones are variable consideration, recognized only once it is probable there won't be a significant reversal, which in practice is usually when the milestone is achieved.

For bankers, this makes pharma earnings lumpy: a big upfront payment can create a one-off loss for the buyer and a one-off revenue spike for the seller. Analysts usually separate acquired R&D and milestone income from recurring results when valuing either company.
