What is the difference between the completed contract method and the percentage-of-completion method for long-term contracts?
These two methods handle long-term contract revenue very differently. Percentage-of-completion recognizes revenue proportionally as work is performed, while completed contract waits until the project is fully finished. The choice has major implications for income smoothing, balance sheet presentation, and tax timing.
What are the components of the balance of payments current account and why does it matter for currency analysis?
The current account records trade in goods, services, primary income (investment returns), and secondary income (transfers). Persistent deficits signal that a country is spending more abroad than it earns, requiring offsetting capital inflows.
How do you create synthetic positions using options, and what is put-call parity?
Synthetic positions replicate the payoff of one instrument using a combination of others. Put-call parity (c + PV(X) = p + S) is the equation that makes this possible, allowing you to create synthetic stock, calls, puts, or risk-free bonds.
How does coupon reinvestment risk affect a bond's realized total return?
Coupon reinvestment risk is the risk that the cash flows you receive from a bond (coupons) will be reinvested at a rate different from the yield to maturity (YTM) that was assumed when you purchased the bond.
How do I implement a three-stage DDM with declining growth in the middle period?
The three-stage DDM has a high-growth phase, a transition phase with linearly declining growth, and a stable mature phase. Calculate dividends in each phase using the declining growth rate, compute terminal value using the Gordon Growth Model at the stable rate, then discount all cash flows back to today.
What is the difference between a market maker and a specialist in equity trading?
Market makers and specialists both provide liquidity, but they operate in different market structures. Market makers compete in dealer/OTC markets like NASDAQ, while specialists (DMMs) are assigned to a single stock on auction exchanges like the NYSE with an obligation to maintain an orderly market.
How do fair value adjustments to PP&E affect the equity method income reported by the investor?
This is one of the most commonly tested equity method mechanics on CFA Level II. The investor must depreciate its share of the fair value adjustment to PP&E over the asset's remaining useful life, which reduces the equity income pickup each period.
What are the main categories of alternative investments and why should traditional portfolio managers care?
Alternative investments encompass any asset class outside of traditional publicly traded equities, fixed income, and cash. For CFA Level I, you need to understand five major categories: hedge funds, private equity, real estate, commodities, and infrastructure, plus the role each plays in portfolio construction.
What are the real-world differences between accrual and cash basis accounting, and why does the CFA curriculum focus on accrual?
Accrual accounting records economic events when they occur, regardless of when cash changes hands. Cash basis accounting records transactions only when cash is received or paid. The CFA curriculum emphasizes accrual because it provides a more accurate picture of a company's financial performance over a period.
How do I decompose implementation shortfall into its components, and what does each piece represent?
Implementation shortfall measures the total cost of executing an investment decision by comparing the paper portfolio return to the actual portfolio return. It decomposes into explicit costs, delay cost, market impact cost, and opportunity cost.
What's the difference between dirty price and clean price, and why do bond markets quote the clean price but settle at the dirty price?
Clean price strips out accrued interest to make bond prices comparable over time, eliminating the sawtooth pattern caused by interest building up between coupon dates. Markets quote clean prices for comparability but settle at dirty prices (clean + accrued interest) because the buyer must compensate the seller for interest earned.
How does the IPO book-building process actually work, and why is it preferred over a fixed-price offering?
In a book-building IPO, the lead underwriter collects non-binding indications of interest from institutional investors before setting the final offer price. This contrasts with fixed-price offerings where the price is set upfront. Book building wins because it extracts information from investors and reduces underpricing.
How do I calculate NPV when the cash flows are unequal each year? I keep getting the wrong answer.
Great question — unequal (or "mixed") cash flow problems are among the most commonly tested TVM concepts on the CFA Level I exam. The key insight is that each cash flow must be discounted individually back to the present, and then you sum them all up.
What are the main portfolio rebalancing strategies and how do you choose between them?
Rebalancing realigns portfolio weights back toward the strategic asset allocation after market drift. The three main approaches are calendar rebalancing, percentage-of-portfolio (threshold) rebalancing, and tactical rebalancing, each with distinct tradeoffs between simplicity, cost, and risk control.
What constitutes a strong risk culture and how can you actually measure it?
Risk culture is the set of norms, attitudes, and behaviors within an organization that shapes how risk is identified, discussed, and acted upon. The FSB identifies four pillars: tone from the top, accountability, effective challenge, and incentive alignment.
How do banks conduct liquidity stress tests and what scenarios do they typically model?
Liquidity stress testing simulates severe but plausible funding disruptions to determine whether the bank can survive without external support. Banks typically model three scenarios: idiosyncratic stress, market-wide stress, and a combined scenario, each with different assumptions about deposit runoff, wholesale funding rollover, and asset liquidation discounts.
How does scenario analysis work for operational risk, and how do banks combine it with historical data?
Scenario analysis bridges the gap between historical loss data and the need to capitalize against catastrophic operational failures. Banks run structured expert workshops to estimate frequency and severity of plausible but severe events, then calibrate these against internal and external loss data.
Why does Basel III include a leverage ratio when we already have risk-weighted capital ratios?
The leverage ratio exists precisely because risk-weighted ratios can be gamed or miscalibrated. Before the 2008 crisis, many banks showed healthy CET1/RWA ratios while running actual leverage of 30:1 or higher by loading up on assets with low risk weights.
What is the TNFD framework, and how does nature-related financial risk extend beyond climate risk?
The TNFD framework addresses nature-related financial risks beyond climate, including biodiversity loss, ecosystem degradation, and resource depletion. Using the LEAP approach, organizations map nature interfaces, assess dependencies and impacts, and prepare disclosures across governance, strategy, risk management, and metrics.
What is incremental VaR, and how does it differ from marginal VaR when sizing a discrete new trade?
Incremental VaR measures the exact change in portfolio VaR from adding a discrete trade, calculated as VaR(portfolio + trade) minus VaR(portfolio). Unlike marginal VaR, which is a local derivative approximation, incremental VaR captures the full nonlinear impact of realistic position sizes.
