Financial Metrics and Attribution in Real Estate

Financial metrics are essential for quantifying and evaluating the performance of real estate investments. Attribution analysis then decomposes this performance to understand the drivers of success or failure. This chapter provides a comprehensive exploration of financial metrics and attribution methodologies specifically tailored for real estate, equipping investment professionals with the tools to rigorously assess performance and inform strategic decision-making.

Overview

This chapter delves into the crucial intersection of financial metrics and attribution analysis within the context of real estate investment. Understanding how to effectively measure and attribute performance is paramount for informed decision-making, risk management, and ultimately, achieving superior investment outcomes in this asset class.

The following key concepts will be explored:

• Return Measurement Methodologies: Examination of both time-weighted and money-weighted (IRR) return calculations, including their relative strengths and weaknesses in the context of real estate's unique characteristics such as infrequent valuations and illiquidity.
• Real Estate-Specific Return Metrics: Exploration of industry-standard metrics like the NCREIF Property Index (NPI) methodology and IPD benchmarks, including their calculation and underlying assumptions related to cash flow patterns and capital expenditures.
• Risk-Adjusted Performance Measures: Analysis of Sharpe Ratio, Information Ratio, and Beta, evaluating their applicability and limitations in assessing risk-adjusted returns in the real estate sector, particularly considering appraisal smoothing and pricing lags.

Return Metrics

Time-Weighted Return (TWR)

• Also known as the geometric mean return.
• Preferred in performance measurement because it removes the effects of cash flows controlled by the investor.

• Calculated by linking the returns for each sub-period.

  1. Calculate the return for each period: r_i = (EMV + CF - BMV) / BMV
  2. Compound the returns: TWR = [(1 + r_1) * (1 + r_2) * ... * (1 + r_N)] - 1

  Where:
  * r_i is the return for period i
  * N is the number of periods
  * EMV is the ending market value of investment
  * BMV is the beginning market value of investment
  * CF is the net cash flows for the period (contributions are positive, distributions are negative)
  * TWR differs from the arithmetic-mean return in its compounding effect, with TWR being preferred in performance measurement, whereas arithmetic returns are preferred in statistical analysis of performance. The two will differ with more volatility in the return series by roughly half of the variance of the returns. The volatility is captured by the standard deviation: Difference ≈ σ^2 / 2

  Where:
  * σ is the standard deviation of returns.

Internal Rate of Return (IRR)

• The discount rate at which the net present value (NPV) of all cash flows from a project equals zero.
• Sensitive to the timing and magnitude of cash flows.
• Can be more suitable for non-operating real estate investments with volatile cash flows.
• May not be computable if a highly levered property is valued below the outstanding level of debt.

Modified Dietz Method

• Approximates TWR by weighting cash flows based on the amount of time they are in the portfolio.

• The Modified Dietz formula is as follows: Return = (EMV - BMV - CF) / (BMV + W * CF)

  Where:
  * EMV is the ending market value of investment
  * BMV is the beginning market value of investment
  * CF is the net cash flows for the period (contributions are positive, distributions are negative)
  * W is the weighting for number of days in the period.

NCREIF Property Index (NPI) Methodology

• Uses quarterly cash flows derived from a typical real estate cash-flow statement.
• Assumes partial sales (PS) and capital improvements (CI) occur in the middle of the performance period and are therefore weighted by half.
• Net operating income (NOI) is assumed to be derived from the collection of rents that occur at the end of each month.
• NCREIF operating property returns: (NOI + 0.5*PS - 0.5*CI) / BMV

• NCREIF levered operating property returns: (NOI - IE + 0.5*PS - 0.5*CI) / (BMV + BL + 0.5*ND - 0.5*PP - 0.5*OP)

  Where:
  * NOI is the net operating income
  * PS is partial sales
  * CI is capital improvements
  * EMV is the ending market value of investment
  * BMV is the beginning market value of investment
  * IE is interest expense
  * BL is beginning loan balance
  * EL is ending loan balance
  * ND is new debt
  * PP is principal payment
  * OP is other debt payments

IPD Benchmark Methodology

• Uses monthly data.
• Assumes capital expenses (Cexp) are paid at the beginning of the month and capital receipts (Crec) at the end of the month.

• IPD operating property returns: (NI + CV - Cexp + Crec) / (CV + Crec)

  Where:
  * NI is net income
  * CV is capital value
  * Cexp is capital expenses
  * Crec is capital receipts

Risk-Adjusted Return Metrics

Sharpe Ratio

• Measures the risk-adjusted return of an investment relative to the risk-free rate.

• Calculated as: Sharpe Ratio = (r_p - r_f) / σ_p

  Where:
  * r_p is the portfolio return
  * r_f is the risk-free rate of return
  * σ_p is the standard deviation of the portfolio return.

Information Ratio

• A variation of the Sharpe Ratio that replaces the risk-free rate with the portfolio benchmark return.
• Measures the consistency with which an investment exceeds the return of its benchmark.

• Calculated as: Information Ratio = (r_p - r_b) / Tracking Error

  Where:
  * r_p is the portfolio return
  * r_b is the benchmark return
  * Tracking Error is the standard deviation of the excess return (r_p - r_b).
  * Negative information ratios typify underperformance, and ratios above 0.45 signify consistent portfolio outperformance.

Capital Asset Pricing Model (CAPM)

• Relates the risk of an asset to its expected return.

• r_p = r_f + β * (r_m - r_f)

  Where:
  * r_p is the expected return on the portfolio
  * r_f is the risk-free rate of return
  * β (Beta) is the systematic risk of the asset, i.e., the sensitivity of the asset's return to market movements.
  * r_m is the expected return on the market

Beta

• Measures the relative sensitivity of a property's or portfolio's return to the market.
• A beta of 0 implies no relationship to the market.
• A beta of 1 implies the portfolio's returns move in sync with the overall market.

Alpha

• The risk-adjusted excess return of the portfolio relative to the return of the benchmark.

• Calculated as: α = r_p - [r_f + β * (r_b - r_f)]

  Where:
  * r_p is the portfolio return
  * r_b is the benchmark return

Performance Attribution

Attribution Analysis

• An analysis of the ex-post performance of a portfolio that attempts to explain the excess return in respect to active management decisions.
• Aims to provide evidence of the effects of the organization's strategy.

Brinson Attribution Model

• A framework to represent each strategic decision measured in the context of active or passive exposure to the benchmark.
• Separates the excess return into two main components: asset selection and allocation/market timing.

• Methods include:

  • Method I: Selection Effect incorporates Interaction Effect.
  • Method II: Allocation Effect incorporates Interaction Effect.
  • Method III: Original Brinson-Hood-Beebower model with separate Selection, Allocation, and Interaction components.

• Allocation Contribution: The effects of a strategic over- or under-weighting to a sector which is over- or under-performing.

• Selection Contribution: The sector's relative performance multiplied by the portfolio's exposure to this sector.
• Interaction Contribution: The effects from the combination of both selection and allocation.

Brinson-Hood-Beebower Model (Method III)

• Excess Return = Selection Effect + Allocation Effect + Interaction Effect
• Selection Effect = Σ [(Wps - Wbs) * Rbs]
• Allocation Effect = Σ [Wbs * (Rps - Rbs)]

• Interaction Effect = Σ [(Wps - Wbs) * (Rps - Rbs)]

  Where:
  * Rps is the portfolio sector return
  * Rbs is the benchmark sector return
  * Rb is the benchmark return
  * Wps is the weight of the sector in the portfolio
  * Wbs is the weight of the sector in the benchmark

Method I

• Selection Effect = Σ [Wps * (Rps - Rb)]
• Allocation Effect = Σ [(Wps - Wbs) * Rb]

Method II

• Selection Effect = Σ [Wbs * (Rps - Rbs)]
• Allocation Effect = Σ [(Wps - Wbs) * Rps]

Financial Effects (De-Levering)

• Leverage can significantly impact a portfolio, and it is important to isolate its effects.
• The Modigliani-Miller theorem can be used to convert levered returns to unlevered returns.

• Requity = Rasset + (Rasset - k_d) * (LTV / (1 - LTV))

  Where:
  * Requity is the levered return
  * Rasset is the unlevered return
  * k_d is the effective interest rate
  * LTV is the loan-to-value ratio
  * Estimate the ODCE index without debt: RODCE_unlevered = RODCE - (1- LTVODCE) * (RODCE - k_d)
  Where:
  * RODCE is the reported ODCE return
  * NoteApprEffectODCE is the reported mark-to-market value of the debt in ODCE
  * k_d is the average interest rate (derived from the NPI)
  * LTVODCE is the reported loan-to-value ratio of ODCE

• To de-lever fund-level investment returns: Return_delevered = (NII + IE + NA*OS) / (WNA+ LB*OS - CNA)
  Where:
  * NII is net investment income
  * IE is interest payments
  * LB is loan balance
  * OS is the ownership share (either contract rate or effective rate)
  * NA is the note appreciation for period
  * CNA is the cumulative note appreciation
  * WNA is the weighted net assets

• To remove cash effects from a portfolio: Return_no_cash = (NII + PA) / (WNA - CB*OS)
  Where:
  * NII is the net investment income
  * PA is the portfolio appreciation
  * CI is the cash income
  * OS is the ownership share (either contract rate or effective rate)
  * CB is the cash balance
  * WNA is the weighted net assets

• To estimate the ODCE index without cash:
  URODCE = RODCE - Wcash * Rcash
  Where:
  * URODCE is the de-levered ODCE return
  * Rcash is the estimated return on cash (30-day Treasury-bill)
  * Wcash is the reported cash level in ODCE

Components of Return/IRR Attribution

• Decomposes the effects of a return into its income versus growth components.
• Uses the dividend discount model, similar to a typical underwriting pro forma.
• Property Value = NOI / (Discount Rate - Growth Rate)

Summary

This chapter focuses on financial metrics and attribution methods used in real estate performance analysis, providing tools to understand and evaluate investment performance. It covers calculations, benchmarks, and methods for attributing returns to specific strategic decisions.

• Time-Weighted Return (TWR): Preferred for performance measurement because it eliminates the effects of cash flows. However, Internal Rate of Return (IRR) might be more suitable for highly levered or volatile assets. TWR is calculated considering the compounding effect.

• NCREIF Property Index (NPI) and IPD benchmarks: These indices are foundational for real estate performance measurement, using variations of the modified Dietz methodology. They calculate operating property returns, considering factors like net operating income (NOI), partial sales, capital improvements, interest expense, and loan balances.

• Risk-Adjusted Returns: Metrics like the Sharpe Ratio and Information Ratio are crucial for evaluating performance relative to risk. The Sharpe Ratio measures excess return over the risk-free rate, while the Information Ratio compares portfolio return to a benchmark.

• Beta and Alpha: The Capital Asset Pricing Model (CAPM) uses Beta and Alpha to measure systematic risk and risk-adjusted excess return, respectively. Beta measures the sensitivity of an asset's returns to market movements, while Alpha quantifies the excess return relative to the benchmark.

• Brinson-Style Attribution: This method separates excess return into asset selection and allocation effects. It helps identify if outperformance is due to selecting better assets (selection) or strategically overweighting certain sectors (allocation). Three methods (I, II, and III) exist, each with different ways of handling the interaction effect.

• De-leveraging Techniques: The chapter discusses techniques to remove the effects of leverage to understand the underlying real estate strategy. This often involves using derivations of the Modigliani-Miller theorem and adjusting income statements and balance sheets.

• Income/Expense Attribution: Returns can be attributed to income versus growth components, similar to discounted cash flow analysis. This decomposition offers insights into how much of the return comes from income generation versus capital appreciation.
