What is the difference between permanent and temporary differences in deferred tax accounting?
Temporary differences reverse over time and create deferred tax assets or liabilities, while permanent differences never reverse and therefore create no deferred tax items. Permanent differences cause the effective tax rate to differ from the statutory rate, which is a key analytical insight tested on the CFA exam.
What does it mean when an issuer's credit curve inverts and what does it signal?
Credit curve inversion occurs when short-term credit spreads exceed long-term spreads, signaling that the market expects the issuer to face imminent default or a near-term credit event.
How do I analyze premiums in precedent transactions for equity valuation?
Precedent transaction premiums are calculated as the deal price minus the undisturbed share price, divided by the undisturbed price. Segment transactions by deal type (strategic vs. financial, hostile vs. friendly), exclude outliers, and apply the relevant premium range to the target.
What are the industry life cycle stages and their investment implications?
The five industry life cycle stages — embryonic, growth, shakeout, mature, and decline — each have distinct implications for profitability, competition, and investment strategy. Growth-stage firms justify high multiples, while mature firms offer dividends and stability.
How are actuarial gains and losses on defined benefit pensions treated in OCI, and when do they get amortized?
Under US GAAP, actuarial gains and losses are initially recognized in OCI and amortized to pension expense only when accumulated amounts exceed the 10% corridor. Under IFRS, they remain in OCI permanently and are never recycled.
How does accelerated tax depreciation create a deferred tax liability, and will it ever reverse?
A deferred tax liability arises when accelerated tax depreciation creates higher deductions early on, reducing current taxes payable below book tax expense. The DTL builds in early years when tax depreciation exceeds book depreciation, then reverses as the pattern flips.
How does prospect theory and loss aversion actually affect portfolio construction decisions?
Prospect theory, developed by Kahneman and Tversky, fundamentally challenges the classical assumption that investors evaluate outcomes based on final wealth levels. Instead, people evaluate outcomes relative to a reference point — typically their purchase price or a recent portfolio peak.
What is the TCFD framework and how do financial institutions apply it to climate risk disclosures?
The TCFD framework has four pillars: Governance, Strategy, Risk Management, and Metrics & Targets. Banks must disclose how climate risks affect their portfolios through scenario analysis, integration into credit underwriting, and quantitative measures like financed emissions.
What is duration gap analysis and how do banks use it to manage interest rate risk?
Duration gap analysis measures the sensitivity of a bank's equity to interest rate changes. The gap equals asset duration minus leverage-adjusted liability duration. A positive gap means equity falls when rates rise — the classic risk of borrowing short and lending long.
What are CoVaR, SRISK, and MES, and how do they measure systemic risk differently?
Systemic risk measures attempt to quantify how much a single institution's distress contributes to system-wide risk. CoVaR, MES, and SRISK each answer a different question about the relationship between institutions and the financial system.
How do you design and implement a single-factor stress test for a portfolio?
A single-factor stress test examines how a portfolio's value changes when ONE risk factor is shocked by a large amount while all other factors remain unchanged. It complements VaR by exploring extreme scenarios.
How does a CCP's default waterfall work and why is it important for financial stability?
A CCP's default waterfall is the predefined sequence of financial resources used to absorb losses when a clearing member defaults. It starts with the defaulter's margin and fund contribution, then the CCP's own capital, before reaching mutualized resources from surviving members.
How do banks conduct operational risk scenario analysis?
Operational risk scenario analysis is a structured process where subject-matter experts construct plausible-but-severe loss scenarios to capture tail risks that historical data alone cannot reveal...
What is retrocession and why do reinsurers buy it?
Retrocession is reinsurance purchased by reinsurers to manage peak-zone accumulations, often via ILS, sidecars, and ILWs.
How do banks estimate A-IRB parameters PD, LGD, EAD under Basel?
A-IRB lets banks estimate PD, LGD, EAD internally. PD from rating grades with 5+ yr data; LGD downturn with 7+ yr data; EAD via CCF on undrawn commitments. Subject to floors and use test...
How should I handle conflicts of interest under Standard VI?
Standard VI requires disclosure of all conflicts of interest, maintaining transaction priority (clients first, personal last), and disclosing referral fee arrangements. When in doubt, always disclose.
How does short selling actually work mechanically? What are the risks?
Short selling is betting that a stock's price will decline. You borrow shares, sell them, wait for the price to drop, buy them back cheaper, and return them. The critical risk is unlimited loss potential since there's no cap on how high a price can rise.
Can someone explain callable and putable bonds? How do embedded options affect bond pricing?
Embedded options give one party the right to alter the bond's cash flows, and they fundamentally change how you value the bond. Callable bonds trade at a discount to straight bonds, while putable bonds trade at a premium.
How does purchase accounting affect inventory and COGS after an acquisition?
Purchase accounting writes up acquired inventory to fair value, temporarily inflating COGS and depressing gross margins in the first period after acquisition. Analysts should add back the inventory step-up to assess normalized operating performance.
What is the financial statement impact of capitalizing an operating lease?
Capitalizing an operating lease increases both assets and liabilities on the balance sheet, front-loads expenses on the income statement, and reclassifies part of the cash payment from CFO to CFF. This affects leverage ratios, asset turnover, EBITDA, and CFO.
