CFA Exam Question of the Day

Rationale:
The calculation of effective duration is crucial for bonds with embedded options, such as the callable corporate bond in this scenario, because it accounts for how the bond's cash flows and optionality change with shifts in interest rates. Unlike modified duration, which assumes fixed cash flows, effective duration uses observable price changes for a given change in yield, reflecting the true interest rate sensitivity of the bond. To calculate effective duration, the formula is: Effective Duration = (P- - P+) / (2 * P0 * Δy) Where: P- = Bond price if yield decreases = $103.75 P+ = Bond price if yield increases = $101.20 P0 = Current bond price = $102.50 Δy = Change in yield = 10 basis points = 0.0010 Plugging in the given values: Effective Duration = ($103.75 - $101.20) / (2 * $102.50 * 0.0010) Effective Duration = $2.55 / (2 * $0.1025) Effective Duration = $2.55 / $0.205 Effective Duration = 12.4390... which rounds to 12.44. The reported modified duration of 9.85 is not applicable here because the bond is callable, meaning its cash flows are not fixed and its price-yield relationship is non-linear due to the embedded option. The credit spread of 120 basis points is also extraneous information for this specific calculation, as effective duration directly uses the observed price changes resulting from benchmark yield shifts. The value of 24.88 results from omitting the factor of 2 in the denominator of the effective duration formula, which incorrectly doubles the calculated duration. The value of 124.39 likely arises from incorrectly using a change in yield of 1 basis point (0.0001) instead of 10 basis points (0.0010) in the denominator, leading to an overestimation of duration by a factor of 10. The value of 0.12 results from mistakenly using a change in yield of 10% (0.10) instead of 10 basis points (0.0010) in the denominator, which significantly underestimates the duration.

Rationale:
The Modified Internal Rate of Return (MIRR) is a capital budgeting tool that addresses some of the limitations of the traditional Internal Rate of Return (IRR) by allowing for different rates for discounting negative cash flows and compounding positive cash flows. The calculation involves three main steps: 1. Calculate the present value of all cash outflows, discounted at the financing cost. 2. Calculate the future value of all cash inflows, compounded at the reinvestment rate. 3. Calculate the discount rate (MIRR) that equates the absolute present value of the outflows to the future value of the inflows over the project's life. In this project: 1. The present value of the initial outflow at Year 0 is $1,200,000. Since there are no other outflows, the present value of outflows is simply $1,200,000. The financing cost of 9% would be used to discount any future outflows, but it does not affect the Year 0 outflow. 2. The future value of the positive cash inflows, compounded at the specified reinvestment rate of 11%, is calculated as follows: * Year 1 inflow: $500,000 * (1 + 0.11)^(3-1) = $500,000 * (1.11)^2 = $616,050 * Year 2 inflow: $600,000 * (1 + 0.11)^(3-2) = $600,000 * (1.11)^1 = $666,000 * Year 3 inflow: $400,000 * (1 + 0.11)^(3-3) = $400,000 * (1.11)^0 = $400,000 * Total Future Value of Inflows = $616,050 + $666,000 + $400,000 = $1,682,050 3. The MIRR is the discount rate (r) that equates the present value of outflows to the future value of inflows over the 3-year project life: $1,200,000 = $1,682,050 / (1 + r)^3 (1 + r)^3 = $1,682,050 / $1,200,000 = 1.40170833 1 + r = (1.40170833)^(1/3) = 1.119001 r = 0.119001 or 11.90%. One incorrect answer, "11.18%", results from incorrectly using the financing cost of 9% as the reinvestment rate for positive cash flows. If 9% were used, the future value of inflows would be $500,000(1.09)^2 + $600,000(1.09)^1 + $400,000 = $594,050 + $654,000 + $400,000 = $1,648,050. The MIRR would then be ($1,648,050 / $1,200,000)^(1/3) - 1 = 11.18%. This is incorrect because the problem explicitly states that positive cash flows can be reinvested at 11%. Another incorrect answer, "19.56%", represents the project's standard Internal Rate of Return (IRR). Calculating the IRR for the given cash flows (-$1,200,000, $500,000, $600,000, $400,000) yields 19.56%. While IRR is a widely used metric, it implicitly assumes that cash flows are reinvested at the IRR itself, which may not be a realistic assumption. MIRR addresses this limitation by allowing for a more appropriate, specified reinvestment rate. A third incorrect answer, "11.76%", is obtained if the weighted average cost of capital (WACC) of 10.5% is incorrectly used as the reinvestment rate for positive cash flows. If 10.5% were used as the reinvestment rate, the future value of inflows would be $500,000(1.105)^2 + $600,000(1.105)^1 + $400,000 = $608,012.50 + $663,000 + $400,000 = $1,671,012.50. The MIRR would then be ($1,671,012.50 / $1,200,000)^(1/3) - 1 = 11.70%. The WACC is a distractor in this context, as the problem provides a specific reinvestment rate for MIRR calculation, and the small numerical difference is likely due to rounding.

Rationale:
The full (dirty) price of a bond is determined by adding the bond's clean price to the accrued interest. Accrued interest represents the portion of the next coupon payment that the seller is entitled to, calculated from the last coupon payment date up to, but not including, the settlement date. First, determine the clean price of the bond. The bond is quoted at 98.50 per 100 of par value. For a $1,000 face value bond, the clean price is $985.00 (0.9850 * $1,000). Next, calculate the semi-annual coupon payment. An annual coupon rate of 5.00% on a $1,000 face value bond equates to an annual coupon of $50.00. Since payments are semi-annual, each coupon payment is $25.00 ($50.00 / 2). Then, calculate the number of accrued days using the 30/360 day count convention. The last coupon payment was on October 15, 2023, and the settlement date is December 15, 2023. * Days in October (from 15th to 30th): 30 - 15 = 15 days * Days in November: 30 days * Days in December (up to 15th): 15 days * Total accrued days = 15 + 30 + 15 = 60 days. The number of days in a semi-annual coupon period under the 30/360 convention is typically 180 days (6 months * 30 days/month). Now, calculate the accrued interest (AI): AI = (Accrued days / Days in coupon period) * Semi-annual coupon payment AI = (60 / 180) * $25.00 = (1/3) * $25.00 = $8.3333... Finally, calculate the full (dirty) price: Dirty Price = Clean Price + Accrued Interest Dirty Price = $985.00 + $8.3333... = $993.33. The value of $985.00 represents only the clean price of the bond. It incorrectly omits the accrued interest, which is a component of the full price a buyer must pay. The value of $993.20 suggests a slight miscalculation of the accrued interest. For instance, if the number of accrued days was mistakenly calculated as 59 days instead of 60 days under the 30/360 convention, the accrued interest would be ($59/180) * $25.00 = $8.1944..., leading to a dirty price of $985.00 + $8.19 = $993.19 (approximately $993.20). Such an error would stem from an incorrect application of the specified day count convention. The value of $1,010.00 results from a common conceptual error: adding a full semi-annual coupon payment ($25.00) to the clean price ($985.00). The buyer is only obligated to pay for the portion of the coupon that has *accrued* since the last payment, not the entire upcoming coupon payment.

Rationale:
The correct valuation using direct capitalization requires calculating the Net Operating Income (NOI) by subtracting only operating expenses from the Effective Gross Income (EGI), and then dividing by the market capitalization rate. First, calculate Effective Gross Income (EGI): EGI = Potential Gross Income × (1 - Vacancy Rate) EGI = $1,200,000 × (1 - 0.05) = $1,200,000 × 0.95 = $1,140,000 Next, identify and sum the relevant operating expenses. Depreciation expense, interest expense, and one-time tenant improvement allowances are NOT considered operating expenses for NOI calculation in direct capitalization. Depreciation is a non-cash accounting expense, interest is a financing cost, and a one-time TI allowance is a capital expenditure, not a recurring operational cost. Operating Expenses = Property Taxes + Insurance + Property Management Fees + Utilities & Maintenance Operating Expenses = $150,000 + $30,000 + (0.04 × $1,140,000) + $80,000 Operating Expenses = $150,000 + $30,000 + $45,600 + $80,000 = $305,600 Now, calculate Net Operating Income (NOI): NOI = EGI - Operating Expenses NOI = $1,140,000 - $305,600 = $834,400 Finally, calculate the property's market value: Market Value = NOI / Market Capitalization Rate Market Value = $834,400 / 0.0650 = $12,836,923.08, which rounds to $12,837,000. The option calculating a value of $11,300,000 incorrectly includes annual depreciation expense in the operating expenses, which is a non-cash item and not relevant for NOI in direct capitalization. The option calculating a value of $9,760,000 incorrectly includes annual interest expense on the mortgage in the operating expenses. Interest is a financing cost, not an operating expense of the property itself. The option calculating a value of $7,452,000 incorrectly includes depreciation expense, interest expense, AND the one-time tenant improvement allowance as part of the recurring operating expenses, which significantly understates the NOI and thus the property value.

Rationale:
The primary risk objective in an Investment Policy Statement (IPS) must fundamentally align with the client's ability to bear risk, known as risk capacity. In this scenario, despite the investment committee's expressed high risk tolerance and long time horizon, the endowment's moderately underfunded status, limited liquidity profile, and upcoming capital expenditure commitments significantly constrain its capacity to absorb potential capital losses. For a fiduciary managing an endowment, preserving capital to meet ongoing obligations (spending rate, capital expenditures) and improving its funded status takes precedence over aggressive growth aspirations if such aspirations threaten the institution's financial stability. Therefore, the endowment's financial capacity to withstand losses is the most critical factor informing the primary risk objective. Prioritizing the investment committee's expressed preference for aggressive growth strategies misinterprets the hierarchy of risk factors. While risk tolerance is important, risk capacity often sets a binding constraint, especially for institutional clients with ongoing liabilities. Ignoring capacity in favor of tolerance would be imprudent. Focusing on the aspirational return target incorrectly places the return objective as the primary driver of the risk objective. A prudent investment process first defines an appropriate risk level based on capacity and tolerance, and only then establishes a return objective that is consistent with that defined risk. Setting a return target without first defining an achievable and appropriate risk level is a flawed approach. Considering the historical volatility of the endowment's current asset allocation relative to its peer group benchmarks is a relevant input for evaluating and monitoring risk, or for making tactical adjustments. However, it is a secondary consideration to the fundamental determination of the endowment's intrinsic risk capacity and its strategic risk objective, which are rooted in its financial situation and liabilities.
