Question 1 of 21
Under IFRS, a lessee's accounting treatment for an operating lease versus a finance lease is:
id: 1
model: Claude 4.5
topic: Lease Classification
Explanation
<h3>First Principles Thinking: IFRS Lessee Model</h3><p><strong>B is correct.</strong> Start from the fundamental accounting principle that lessees control an asset through a lease contract. IFRS 16 applies a single lessee model: regardless of classification (operating or finance), the lessee recognizes a right-of-use (ROU) asset representing the right to use the leased asset and a corresponding lease liability representing the obligation to make future lease payments. Both are measured at the present value of lease payments at commencement. Subsequently, the lessee depreciates the ROU asset and recognizes interest expense on the liability using the effective interest method. This unified approach eliminates off-balance-sheet financing that existed under previous standards.</p><p>A is incorrect because it describes the old accounting model (pre-IFRS 16) where operating leases were not capitalized and were simply expensed. Under current IFRS, both operating and finance leases require balance sheet recognition by lessees.</p><p>C is incorrect because both operating and finance leases under IFRS require interest expense recognition on the lease liability. The classification distinction exists but does not materially change the lessee's accounting mechanics under IFRS 16.</p>

Regarding lessor accounting for leases, IFRS and US GAAP standards:
id: 2
model: Claude 4.5
topic: Lessor Accounting - IFRS vs US GAAP
Explanation
<h3>First Principles Thinking: Convergence in Standards</h3><p><strong>C is correct.</strong> From first principles, standard-setters aimed for convergence between IFRS and US GAAP during lease accounting reforms. For lessors, both frameworks retained the dual-model approach distinguishing between operating and finance (or sales-type) leases based on transfer of risks and rewards of ownership. The lessor either derecognizes the asset and recognizes a lease receivable (finance/sales-type lease) or keeps the asset on the books and recognizes rental income (operating lease). This treatment is substantially the same across both standards. However, for lessees, IFRS adopted a single model (all leases on-balance-sheet) while US GAAP maintained a dual model with distinct accounting for operating versus finance leases.</p><p>A is incorrect because it overstates differences—lessor accounting is substantially aligned between IFRS and US GAAP, not significantly different in either classification criteria or measurement approaches.</p><p>B is incorrect because while lessor accounting is very similar and shares the same treatment, the word identical is too strong given minor differences in disclosure requirements and implementation details between the standards.</p>
Question 3 of 21
Which of the following is least likely an advantage of leasing an asset compared to purchasing it outright?
id: 3
model: Claude 4.5
topic: Advantages of Leasing
Explanation
<h3>First Principles Thinking: Economic Substance of Leasing</h3><p><strong>C is correct.</strong> Starting from the economic purpose of leasing, it allows asset use without ownership. Key advantages include: (1) lower initial cash outlay since the lessee doesn't purchase the asset, (2) potentially favorable financing terms, and (3) mitigation of obsolescence risk because the lessee can return the asset at lease end rather than bearing disposal/residual value risk. However, guaranteed residual value protection is not a standard feature—in fact, in most leases (especially operating leases), the lessor retains the residual value risk and benefit. Lessees typically do not receive residual value guarantees; they may face penalties if asset condition deteriorates below normal wear and tear, but protection and upside of residual value accrues to the lessor, not the lessee.</p><p>A is incorrect because lower upfront cash commitment is indeed a primary advantage of leasing—the lessee avoids the large capital expenditure required for outright purchase.</p><p>B is incorrect because transferring obsolescence risk to the lessor is a legitimate advantage, particularly relevant for technology or equipment with short useful lives where operating leases allow lessees to upgrade without bearing disposal concerns.</p>
Question 4 of 21
In a defined contribution pension plan compared to a defined benefit plan, the primary risk bearer of investment performance volatility is the:
id: 4
model: Claude 4.5
topic: Defined Contribution vs Defined Benefit Plans
Explanation
<h3>First Principles Thinking: Risk Allocation in Pension Plans</h3><p><strong>B is correct.</strong> From first principles, pension plans allocate risk between employer and employee based on what is "defined" (fixed). In a defined contribution plan, the employer's obligation is fixed—they contribute a specified amount per period. The ultimate pension benefit depends on investment returns on those contributions, which is uncertain. Thus, employees bear investment risk: if assets underperform, retirement income is lower. Conversely, in a defined benefit plan, the benefit amount is fixed by formula (e.g., percentage of final salary), so the employer must ensure sufficient assets exist to pay that promise. If plan assets underperform, the employer must contribute more to meet the defined obligation, meaning the employer bears investment risk.</p><p>A is incorrect because in defined contribution plans, employers do not bear investment risk—their obligation ends with the fixed contribution; employees bear the risk of asset performance determining their ultimate retirement benefit.</p><p>C is incorrect because employees bear investment risk in defined contribution plans, not defined benefit plans. In defined benefit plans, employees receive a predetermined benefit regardless of investment performance, so the employer absorbs investment volatility.</p>
Question 5 of 21
Actuarial risk, defined as the potential for retirement and death timing to differ from expectations, is primarily borne by:
id: 5
model: Claude 4.5
topic: Actuarial Risk in Pension Plans
Explanation
<h3>First Principles Thinking: Longevity and Timing Risk</h3><p><strong>B is correct.</strong> Actuarial risk stems from uncertainty about how long retirees will live and when they will retire. In a defined benefit plan, the employer promises to pay a specific benefit amount for the retiree's lifetime. If retirees live longer than actuarial assumptions predict, the employer must make payments for more years than anticipated, increasing costs. The employer bears this risk because the benefit is defined—longer life means more total payments from the employer's perspective. In a defined contribution plan, the employee receives an account balance; if they live longer, they must stretch that balance across more years, but the employer has no further obligation beyond the original contributions. Thus, employees in DC plans bear longevity risk.</p><p>A is incorrect because while employees in defined contribution plans do bear longevity risk (outliving their assets), the question asks about actuarial risk as defined in pension accounting, which primarily affects the party making ongoing payments—the employer in DB plans.</p><p>C is incorrect because employers in defined contribution plans do not bear actuarial risk—their obligation is limited to the defined contribution amount regardless of when employees retire or how long they live.</p>
Question 6 of 21
Under a defined contribution pension plan, the pension expense recognized in the income statement is equal to:
id: 6
model: Claude 4.5
topic: Defined Contribution Expense Recognition
Explanation
<h3>First Principles Thinking: Matching Principle for DC Plans</h3><p><strong>B is correct.</strong> From the matching principle, expense should reflect the economic cost incurred in the period. In a defined contribution plan, the employer's obligation is simply to contribute a specified amount (e.g., 5% of salary) to employee accounts. Once contributed, the employer has no further obligation—employees own the assets and bear investment risk. Therefore, the accounting is straightforward: the cash payment made into the plan equals the pension expense for that period. If the employer contributes $100,000 in 2025, pension expense is $100,000. There is no complex actuarial calculation or balance sheet pension liability/asset because the employer's obligation ends with the contribution.</p><p>A is incorrect because this describes the measurement approach for defined benefit plans, where the funded status (plan assets minus pension obligation) affects balance sheet presentation. Defined contribution plans do not have employer-held plan assets or pension obligations on the employer's balance sheet.</p><p>C is incorrect because this also relates to defined benefit plans, where actuaries calculate the present value of future benefits. In defined contribution plans, there are no employer-promised future benefits to value—only the current period contribution.</p>
Question 7 of 21
For a defined benefit pension plan, a company must report on its balance sheet:
id: 7
model: Claude 4.5
topic: Defined Benefit Balance Sheet Recognition
Explanation
<h3>First Principles Thinking: Net Funded Status Reporting</h3><p><strong>B is correct.</strong> From accounting principles, assets and liabilities should be reported net when they are interdependent and offsetting. For defined benefit plans, the employer holds plan assets (in trust) to satisfy the pension obligation. IFRS and US GAAP require reporting the net funded status: if the defined benefit obligation (DBO) exceeds the fair value of plan assets, the deficit is recognized as a liability; if plan assets exceed DBO, the surplus is recognized as an asset (subject to asset ceiling limits). The net position is calculated as: Fair Value of Plan Assets − DBO = Net Pension Asset (if positive) or Net Pension Liability (if negative). This reflects the employer's true economic position—whether they are over- or under-funded.</p><p>A is incorrect because plan assets are not reported separately on the employer's balance sheet; they are offset against the pension obligation to show only the net funded status (surplus or deficit).</p><p>C is incorrect because the pension obligation alone is not reported; instead, the net amount (obligation minus plan assets) is reported. Showing only the obligation would ignore the substantial plan assets held to satisfy that obligation, misrepresenting the employer's economic position.</p>
Question 8 of 21
An underfunded defined benefit pension plan appears on the balance sheet as a:
id: 8
model: Claude 4.5
topic: Underfunded Pension Plan Presentation
Explanation
<h3>First Principles Thinking: Liability Classification</h3><p><strong>B is correct.</strong> An underfunded pension plan means the defined benefit obligation exceeds the fair value of plan assets, creating a deficit. From liability classification principles, liabilities are current if expected to be settled within one year or the operating cycle. Pension obligations extend over many years (until and throughout retirement), making them long-term in nature. Therefore, the net pension liability is classified as non-current. The amount recognized equals the funded status deficit: DBO − Fair Value of Plan Assets. For example, if DBO is $10 million and plan assets are $7 million, a $3 million non-current liability is reported. This reflects the long-term nature of the employer's obligation to fund future retirement benefits.</p><p>A is incorrect because pension liabilities are non-current, not current, due to their long-term nature. The liability represents the total net obligation, not just next year's payments, which are funded from plan assets.</p><p>C is incorrect because underfunded pensions are recognized as liabilities on the balance sheet, not as contra-equity accounts. However, certain remeasurement components (actuarial gains/losses under IFRS) are recognized in other comprehensive income, which flows to equity, but the liability itself appears in the liabilities section.</p>
Question 9 of 21
For defined benefit pension plans under IFRS, the components recognized in profit or loss (income statement) include:
id: 9
model: Claude 4.5
topic: DB Pension Income Statement Components
Explanation
<h3>First Principles Thinking: Expense Attribution Under IFRS</h3><p><strong>A is correct.</strong> IFRS IAS 19 separates defined benefit cost components by their nature. Profit or loss (P&L) recognizes: (1) Service cost—the increase in pension obligation from employee service during the period, and (2) Net interest expense or income—calculated as the net pension liability or asset multiplied by the discount rate, reflecting the time value of money on the net obligation. These represent the operating and financing costs of the pension promise. Remeasurement components, which include actuarial gains/losses from changes in assumptions and differences between actual and expected returns on plan assets, are recognized in other comprehensive income (OCI), not P&L, because they are volatile and outside management's control.</p><p>B is incorrect because remeasurement gains or losses are recognized in other comprehensive income under IFRS, not in profit or loss. Only service cost and net interest expense affect P&L.</p><p>C is incorrect because cash contributions are not the basis for expense recognition under defined benefit plans. The expense is based on actuarial calculations of service cost and interest cost, not cash flows, following the accrual basis of accounting.</p>
Question 10 of 21
Under IFRS, remeasurement changes in a defined benefit pension plan are recognized in:
id: 10
model: Claude 4.5
topic: Remeasurement Component Recognition
Explanation
<h3>First Principles Thinking: OCI Treatment of Volatility</h3><p><strong>B is correct.</strong> Remeasurements include actuarial gains and losses (from changes in demographic or financial assumptions about the pension obligation) and the difference between actual returns on plan assets and the amount included in net interest. These are inherently volatile and unpredictable. From first principles, IFRS separates predictable, controllable costs (service cost, interest) from uncontrollable volatility (remeasurements). Remeasurements are recognized immediately in other comprehensive income (OCI) to keep P&L focused on operational performance. Importantly, IFRS prohibits recycling these amounts from OCI to P&L in future periods—they remain in equity, eventually transferring within equity to retained earnings but never affecting profit or loss.</p><p>A is incorrect because remeasurements are explicitly excluded from profit or loss under IFRS; they bypass the income statement and go directly to OCI to reduce earnings volatility.</p><p>C is incorrect because remeasurements are not prior period adjustments (which correct errors); they are current period changes in estimates recognized in current period OCI. They are presented in the statement of comprehensive income, not as retrospective restatements.</p>
Question 11 of 21
The primary difference between US GAAP and IFRS in accounting for defined benefit pension plans is:
id: 11
model: Claude 4.5
topic: US GAAP vs IFRS Pension Accounting
Explanation
<h3>First Principles Thinking: Standard Differences in Volatility Management</h3><p><strong>B is correct.</strong> Both IFRS and US GAAP require balance sheet recognition of the net funded status (plan assets minus obligation). The key difference lies in income statement versus OCI treatment. Under IFRS, service cost and net interest go to P&L while all remeasurements go to OCI (never recycled). Under US GAAP, service cost and interest cost go to P&L, but certain components like prior service costs are initially in OCI and amortized to P&L over time. US GAAP also recognizes expected returns on plan assets in P&L (not actual returns), with the difference going to OCI and amortized. Thus, the treatment and amortization of certain remeasurement components differs between the standards.</p><p>A is incorrect because both standards use OCI for some components; the difference is which components and whether they are recycled. US GAAP does not put all pension costs in P&L—it uses OCI for certain items with subsequent amortization.</p><p>C is incorrect because US GAAP does require balance sheet recognition of the net funded status, just like IFRS. This requirement was introduced by ASC 715 and aligns both standards on balance sheet presentation.</p>
Question 12 of 21
Employee compensation packages include stock-based compensation primarily to:
id: 12
model: Claude 4.5
topic: Stock-Based Compensation Objectives
Explanation
<h3>First Principles Thinking: Agency Theory and Alignment</h3><p><strong>A is correct.</strong> From agency theory, employees (agents) may have interests that diverge from shareholders (principals). Stock-based compensation addresses this by giving employees ownership stakes or value tied to stock price. When employees own stock or options, they benefit from share price increases, aligning their incentives with shareholder wealth maximization. Additionally, stock grants and options typically have vesting periods (e.g., 3-4 years), creating retention incentives—employees must stay to receive the benefit. This dual purpose (alignment + retention) makes stock-based compensation valuable despite requiring no current cash outlay, though it does create expense recognition and shareholder dilution.</p><p>B is incorrect because while stock-based compensation does reduce current cash outlays, it does not maximize employee liquidity—in fact, it reduces it since employees receive illiquid equity that vests over time rather than immediate cash they can spend.</p><p>C is incorrect because stock-based compensation must be recognized as an expense in the income statement under both IFRS and US GAAP, measured at fair value at grant date and recognized over the vesting period. It does not avoid expense recognition.</p>
Question 13 of 21
Stock-based compensation expense is measured using fair value determined at the:
id: 13
model: Claude 4.5
topic: Stock-Based Compensation Measurement
Explanation
<h3>First Principles Thinking: Measurement and Recognition Timing</h3><p><strong>A is correct.</strong> From the measurement principle, the economic cost of compensation is determined when the employer and employee enter into the arrangement. For stock-based compensation, this is the grant date—when the company gives the employee the right to shares or options with specified terms. The fair value of the award is measured at grant date using the stock price (for shares) or an option pricing model (for options). This fair value becomes the total compensation expense, which is then recognized ratably over the vesting period using the matching principle—the period during which the employee provides service to earn the award. For example, a $100,000 grant vesting over 4 years results in $25,000 expense per year.</p><p>B is incorrect because while measurement occurs at vesting date for some awards, stock-based compensation expense is typically measured at grant date and recognized over the vesting period, not immediately in full, to match expense with the service period.</p><p>C is incorrect because both stock options and stock grants are measured at grant date, not exercise date. Exercise date is when options are converted to shares, which is a separate event from the initial measurement and expense recognition.</p>
Question 14 of 21
Which of the following is least likely a key input into option pricing models used to value stock options for compensation purposes?
id: 14
model: Claude 4.5
topic: Option Pricing Model Inputs
Explanation
<h3>First Principles Thinking: Option Valuation Fundamentals</h3><p><strong>C is correct.</strong> Option pricing models (e.g., Black-Scholes, binomial) value options based on factors affecting the probability and magnitude of payoff at exercise. Key inputs include: (1) exercise price and current stock price—determining intrinsic value; (2) volatility—higher volatility increases option value through greater upside potential; (3) time to expiration—longer time increases value; (4) risk-free rate—affecting present value calculations; (5) dividend yield—dividends reduce stock price appreciation, lowering call option value; (6) estimated forfeitures—specific to employee options. Historical EPS growth is not a direct input because option values depend on future stock price distribution (captured by volatility) and cash flows (dividends), not past earnings patterns.</p><p>A is incorrect because exercise price and stock price volatility are fundamental inputs—exercise price defines the strike level, and volatility is the primary driver of option value through uncertainty.</p><p>B is incorrect because risk-free rate and dividend yield are both key inputs—the risk-free rate is used for discounting and drift calculations, while dividend yield reduces the attractiveness of call options since dividends benefit stockholders, not option holders.</p>
Question 15 of 21
The primary advantage to a company of using stock options rather than cash bonuses for employee compensation is:
id: 15
model: Claude 4.5
topic: Stock Options Cash Flow Impact
Explanation
<h3>First Principles Thinking: Cash Conservation and Financing</h3><p><strong>B is correct.</strong> From a cash flow perspective, stock options allow companies to compensate employees without immediate cash expenditure. When options are granted, no cash changes hands—the company simply creates the right for employees to buy shares in the future. Even at exercise, if employees pay the exercise price, cash flows in. This cash conservation is particularly valuable for growth companies or startups that need to preserve cash for operations and investment while still offering competitive compensation. The tradeoff is future dilution of shareholders when options are exercised and new shares are issued, but the cash flow benefit occurs in the present.</p><p>A is incorrect because stock options do require compensation expense recognition in the income statement. The fair value at grant date is measured (using option pricing models) and expensed over the vesting period under both IFRS and US GAAP.</p><p>C is incorrect because stock options do have a dilutive effect when exercised—new shares are issued to option holders, increasing total shares outstanding and diluting existing shareholders' ownership percentage. This dilution is the economic cost shareholders bear in exchange for the company preserving cash.</p>
Question 16 of 21
A lessee choosing to lease rather than purchase equipment with a useful life of 3 years would most likely prioritize:
id: 16
model: Claude 4.5
topic: Lease Economics
Explanation
<h3>First Principles Thinking: Risk Transfer Through Leasing</h3><p><strong>B is correct.</strong> For assets with short useful lives or rapid technological change (like equipment with a 3-year life), obsolescence risk is significant. By leasing, the lessee transfers this risk to the lessor—at lease end, the lessee returns the equipment and can lease newer technology without bearing the burden of disposing of obsolete assets. From an economic decision framework, leasing makes sense when: (1) the asset has high obsolescence risk, (2) the lessee values flexibility, or (3) the lessor can manage residual value better. For equipment with rapid innovation cycles, avoiding being stuck with outdated, low-residual-value assets is a key advantage of leasing.</p><p>A is incorrect because lessees who lease do not retain residual value—the lessor owns the asset and captures any residual value at lease termination. If retaining residual value were the priority, purchasing would be preferred.</p><p>C is incorrect because depreciation tax shields accrue to the asset owner. In an operating lease, the lessor owns the asset and claims depreciation; the lessee deducts lease payments. To maximize depreciation tax shields, the company would need to purchase and own the asset, not lease it.</p>
Question 17 of 21
A lease is most likely classified as a finance lease (or sales-type lease) when it:
id: 17
model: Claude 4.5
topic: Finance Lease Characteristics
Explanation
<h3>First Principles Thinking: Substance Over Form</h3><p><strong>B is correct.</strong> Finance lease classification is rooted in the principle of substance over form. If a lease transfers substantially all the risks (obsolescence, maintenance, residual value loss) and rewards (appreciation, use benefits, residual value upside) of ownership to the lessee, it is economically equivalent to a purchase financed by a loan, regardless of legal title. Both IFRS and US GAAP use indicators such as: title transfer, bargain purchase option, lease term covering major part of economic life (often ≥75%), or PV of lease payments ≥ substantially all fair value (often ≥90%). These tests identify when economic substance is ownership, requiring finance/capital lease treatment.</p><p>A is incorrect because a lease term less than 50% of economic life suggests an operating lease, not a finance lease. Finance leases typically cover the major part (usually ≥75%) of the asset's economic life, indicating the lessee will use most of the asset's value.</p><p>C is incorrect because lease payments significantly below fair rental value would suggest favorable terms that might not transfer risks and rewards. Finance leases typically have payments whose present value approximates the asset's fair value, reflecting that the lessee is effectively purchasing the asset over time.</p>
Question 18 of 21
Under US GAAP, a lessee's accounting for an operating lease differs from a finance lease in that:
id: 18
model: Claude 4.5
topic: US GAAP Lessee Accounting Difference
Explanation
<h3>First Principles Thinking: Expense Pattern Recognition</h3><p><strong>B is correct.</strong> Under US GAAP ASC 842, both operating and finance leases require balance sheet recognition of a right-of-use asset and lease liability. The difference is in income statement presentation. For operating leases, a single lease expense is recognized on a straight-line basis (total lease payments ÷ lease term), similar to rent expense. For finance leases, the lessee recognizes separate amortization of the ROU asset (typically straight-line) and interest expense on the lease liability (effective interest method, declining over time). This creates front-loaded total expense for finance leases: in early years, interest is high, so (amortization + interest) exceeds the operating lease's straight-line expense; later, interest declines, reversing the pattern.</p><p>A is incorrect because under current US GAAP (ASC 842, effective 2019), operating leases are recognized on the balance sheet with a right-of-use asset and lease liability, eliminating off-balance-sheet treatment.</p><p>C is incorrect because both operating and finance leases under US GAAP require recognition of a right-of-use asset. The distinction is in subsequent measurement and expense presentation, not initial recognition on the balance sheet.</p>
Question 19 of 21

id: 19
model: Claude 4.5
topic: Lessor Finance Lease Recognition
Explanation
<h3>First Principles Thinking: Asset Derecognition and Receivable Recognition</h3><p><strong>B is correct.</strong> When a lease transfers substantially all risks and rewards to the lessee (finance/sales-type lease), the lessor has economically sold the asset and provided financing. From the derecognition principle, the lessor removes the underlying asset from the balance sheet because control has transferred. In its place, the lessor recognizes a lease receivable equal to the present value of lease payments—representing the amount owed by the lessee. For a sales-type lease, the lessor also recognizes revenue (sales price) and cost of goods sold (carrying amount) at lease commencement, plus interest income over time as the receivable is collected. This mirrors a seller financing an asset purchase.</p><p>A is incorrect because this describes operating lease accounting by the lessor. In a finance/sales-type lease, the lessor derecognizes the asset and therefore does not record depreciation—the asset is off the books.</p><p>C is incorrect because straight-line rental income recognition is characteristic of operating leases where the lessor retains the asset. In finance leases, the lessor recognizes interest income on the lease receivable using the effective interest method, not rental income.</p>
Question 20 of 21
A company grants stock options with a 4-year vesting period and a grant-date fair value of $400,000. If 10% of the options are expected to be forfeited, the annual compensation expense in Year 1 will be closest to:
id: 20
model: Claude 4.5
topic: Vesting Period Impact
Explanation
<h3>First Principles Thinking: Expected Vesting and Expense Allocation</h3><p><strong>A is correct.</strong> Stock-based compensation expense equals the grant-date fair value adjusted for expected forfeitures, allocated over the vesting period. Start with total compensation: $400,000 grant-date fair value. Apply expected forfeiture rate: if 10% are expected to forfeit, then 90% are expected to vest, so total expense = $400,000 × 0.90 = $360,000. Allocate over vesting period: $360,000 ÷ 4 years = $90,000 per year. In Year 1, the company recognizes $90,000 compensation expense. This reflects the matching principle—spreading the cost of employee service over the period employees earn the award, adjusted for the probability they will actually receive it.</p><p>B is incorrect because it fails to adjust for expected forfeitures, calculating $400,000 ÷ 4 = $100,000. The expected forfeiture rate must be incorporated to avoid overstating expense for options that will not vest.</p><p>C is incorrect because it misapplies the forfeiture adjustment, possibly adding rather than subtracting forfeitures. The correct approach reduces total expense by expected forfeitures since those options will not result in economic cost to the company.</p>
Question 21 of 21
Compared to a defined contribution plan, a defined benefit pension plan exposes the employer to greater risk of:
id: 21
model: Claude 4.5
topic: Pension Plan Risk Comparison
Explanation
<h3>First Principles Thinking: Investment Risk Attribution</h3><p><strong>B is correct.</strong> In a defined benefit plan, the employer promises a specific retirement benefit (e.g., 60% of final salary for life). To fund this, the employer maintains plan assets invested in stocks, bonds, and other securities. If these assets underperform—due to market declines or poor investment choices—the plan becomes underfunded (assets < obligation). The employer must then contribute additional funds to ensure the promised benefits can be paid. This investment risk is substantial and unpredictable, potentially requiring large cash contributions in down markets. In contrast, defined contribution plans transfer investment risk to employees—the employer contributes a fixed amount and has no obligation if investments underperform.</p><p>A is incorrect because employee turnover risk affects both plan types and is not specifically greater for defined benefit plans. In fact, DB plans often have longer vesting periods and portability challenges, potentially creating retention benefits for employers rather than risks.</p><p>C is incorrect because regulatory vesting changes can affect both plan types. Moreover, in defined contribution plans, employee contributions (if any) are typically immediately vested since employees own their own contributions; employer contributions have vesting schedules. This is not a distinguishing risk for DB plans.</p>
