Application of Portfolio Theory to Commercial Real Estate

Executive Summary:

Goals of Model:

Commercial real estate portfolios are not typically analyzed with a quantitative risk measurement. The goal of this practicum is to build a model to assess risk and return for individual real estate assets that would provide investment managers another tool in assessing commercial real estate portfolios and construction of these portfolios. Additionally, a subject portfolio managed by LaSalle Investment Management is used to display model capabilities and results.

Method:

The model is built in excel and aims to analyze risk and return for two situations: (1) Asset/Property level decisions such as the impact of termination options, credit risk, key discounted cash flow variables and lease structure and (2) Portfolio construction decisions including appropriate debt levels, product type allocation, and risk profile of private portfolios vs public securities.

The model uses Monte Carlo simulations in which key uncertainty variables1 in a discounted cash flow analysis are run thru the model 10,000 times to produce 10,000 IRR results. The process takes into account uncertainty of future outcomes and each variable has a defined probability distribution based on historical market volatility. The model has uncertainty variables including: market rent growth, expense growth, downtime, and residual cap rate. In each of these 10,000 scenarios a random number from the probability distribution is selected for each variable. The final results have 10,000 return outcomes that can be plotted, and typically ends up distributed similarly to a normal distribution or ‘bell curve’.

The model is built to apply Modern Portfolio Theory (MPT)2 and Post Modern Portfolio Theory (PMPT)3 to commercial real estate portfolios. MPT was born out of the idea that investment returns should be viewed in light of quantitative risk assessment, and makes the assumption that investors are risk adverse and prefer the highest return for a level of risk (or lowest risk for a level of return).

The statistic used in MPT to assess risk is standard deviation. Standard deviation makes the assumption that a set percentage of results are within a range of the mean. For instance, 68.2% of the results are captured within +/‐ one standard deviation of the mean. (Ie. If you had an asset with an expected return of 8% and a standard deviation of 3%, there is an expected 68.26% chance the asset’s return will be in the range of 5%‐11%. And there is an expected 95.4% chance you would be within +/‐ 2 standard deviations of the mean which would be between 2%‐14%.) The larger the standard deviation, the more risk inherent in the expected returns.

The criticism with MPT surrounds the assumptions that the

1 Uncertainty variables are those that do not have a certain result and are used in arriving at expected returns. 2 MPT was developed in the 1950’s and 1960’s. Was introduced by Harry Markowitz in 1952. 3 PMPT was developed as an improvement in MPT as it appropriately accounts for non-normally distributed data sets. 1 Eric Hines Practicum | Johns Hopkins University

expected investment performance always fits a normal distribution. Standard deviation analysis and the normal distribution are both limited in the fact that they are symmetrical. Using standard deviation implies that there is an equal chance of a worse than expected return than there is of a better than expected return. Furthermore, using the normal distribution to model the pattern of potential investment returns makes investment results with more upside than downside appear more risky than they really are, with the opposite true as well. This leads to potential for investors to misunderstand the potential ‘upside’ or ‘downside’ of a particular investment when considering only typical MPT methodology.

To take into account these criticisms of MPT, PMPT has gained traction among the investment community. PMPT aims to overcome the limitations of MPT by redefining the concept of risk. PMPT recognizes that standard deviation is a poor proxy for investment risk and risk to an investor is the failure to achieve a certain financial goal. PMPT incorporates a metric entitled ‘Downside Risk’ that was developed to incorporate an investor’s goal and defines risk as those outcomes that do not achieve that goal. The statistic is calculated in a similar manner as standard deviation, however only accounts for results that lie below the investors desired return hurdle. The metric measures the volatility of results below the target return.

To integrate return and risk into one statistic, the Sortino ratio can be applied. This statistic is similar to the Sharpe Ratio and measures how many units of excess return are expected for every unit of downside risk. This ratio incorporates the concept of downside risk and is calculated by subtracting the target return from the assets expected return and dividing the result by the previously mentioned downside risk metric. The result is a single number that incorporates expected return results for every unit of risk. The Sortino ratio provides investors a comparison tool to use as a measuring stick for making decisions between different assets and portfolios on a risk/return basis.

Results: 10 Yr Unleveraged Results

12.00% The results show an expected portfolio return of 8.49% 10.00% for a 10 year hold with a standard deviation of 3.21% and 8.00% downside risk of (at a 7.5% target return) of 0.81%. The 6.00% (E) IRR portfolio has a the following Sortino ratio for return Standard Deviation 4.00% Downside Risk expectations: 10 Year Unleveraged: 1.26; 10 Year 2.00% Leveraged: 2.44; 20 Year Unleveraged: 1.42; 20 Year 0.00% Orlando New Jersey Chicago Atlanta San Diego New Jersey Portfolio Leveraged: 3.04. Office Industrial Retail Retail Office Apartments

The results show a few highlights: (1) Diversification is of clear benefit. Portfolio risk metrics are lower than weighted average of assets and portfolio distribution has a positive skew (2) Assets with NNN leases (retail and industrial) exhibited the strongest Sortino ratio’s, and thus the best risk/expected return tradeoff. (3) Leverage for the subject portfolio at the existing levels (~30%) adds expected return without sacrificing significant downside risk.

Asset Management Impacts:

• Termination o The subject portfolio was analyzed assuming all vacant spaces are given tenant termination options three years into the term at both unamortized (at 9%) capital costs (Scenario #1) and 50% of unamortized (at 9%) capital costs (Scenario #2). Tenants are assumed to terminate the lease when it would be financially preferable (costs to continue lease term at market plus termination fee are below remaining obligation) o The San Diego Office asset has the most vacancy and shows the greatest impact: Scenario #1: 23% chance of termination; reduction in expected return of 12 basis points; and increase in downside risk of 7 basis points. Scenario #2: 50% chance of termination; reduction in expected return of 42 bp; and increase in downside risk of 30 bp. o The impact of termination options on expected return and risk is going to vary for each asset. The outcome is based upon: (1) Projected rental rate volatility (2) Negotiated termination payment and (3) Downtime and amount of capital to release tenant spaces. o This tool can quantitatively assess the risk in agreeing to tenant termination options. This could be especially helpful in negotiations with large tenants

This portfolio is maximized on a risk/return basis at debt levels in the range of 50% ‐ 70%. At the 70%‐80% leverage level, the additional expected return for this portfolio is not justified given the return benchmark and by the additional downside risk that leverage creates.

• Product Type Summary o Office – Volatile rent growth patterns, gross leases with narrowing net margins, and high risk premium on resale lead to most volatile return expectations. Market pricing for office assets may be too aggressive given the risk, as this product type has the lowest expected returns and most volatility.

o Apartments – Low rent growth volatility and smallest risk premium on sale lead to low expected return volatility. Investors targeting stability should focus on apartments due to attractive return for every level of risk on a long term perspective. o Retail – NNN leases and minimal tenant capital obligations lead to an excellent return/risk tradeoff. The assets analyzed are well located, grocery anchored neighborhood centers, poorly situated retail would have a different result. o Industrial – NNN leases and minimal tenant capital obligations help to offset volatile market rent growth patterns. With 100% occupancy and low lease rollover until 2013, this portfolio benefits from stable in place dynamics.

To arrive at the downside deviation, continuous ten year results were analyzed for each comparative benchmark. o The results show that the subject portfolio of real estate assets is efficient from a return/risk basis as compared to NCREIF and S&P 500. The bond data points show the lowest risk, while the subject portfolio along with NCREIF were shown to have lower downside volatility compared to the S&P 500.

Future Applications

This model has the ability to analyze all product types and has the ability to incorporate analytical capability that are unavailable in the market accepted valuation software. Investors and investment managers can benefit from understanding it’s expected risk/return profile for their existing assets and location on the efficient frontier. Given the level of detail in the model, many different types of analytical decisions made in the real estate industry can benefit from this type of risk analysis.

Problem in need of solution – Quantitative Real Estate Risk Analysis

Commercial real estate portfolios are not typically analyzed with quantitative risk measurement. Arriving at a model to assess risk and return would provide investment managers another tool in assessing commercial real estate portfolios and construction of these portfolios.

Assessing risk has largely been a qualitative assessment in assigning values and making investment decisions for commercial real estate. Investment decisions are typically made with a benchmark return in mind, however it is unusual to see quantitative analysis done to compare risk levels of potential investments with similar expected returns.

A potential improvement to the existing model is to introduce elements of Modern Portfolio Theory (MPT) and Post‐Modern Portfolio Theory (PMPT) into quantitative real estate investment analysis. MPT is based on the assumption that investors are risk adverse, suggesting that if an investor is given the choice of two assets with the same expected return, the investor would prefer the less risky asset.

Quantitative modeling results do not solely make a real estate investment decision; however they do give the decision maker another data point to fully assess an investment decision.

Issues Surrounding Problem and Current Applications

The current standard valuation analysis for real estate is composed of three methods: cost approach, comparable sales approach and discounted cash flow approach. The cost and comparable sale approaches are static and do not account for future projections in performance or cash flow. The discounted cash flow analysis provides the opportunity to analyze projects based on expected results that are determined by market assumptions. The current standard for this analysis is the Argus software. The limitation with the current standards for valuation is that there is no account for the uncertainty of the future projected cash flows. The inputs for Argus are all static and are successful in arriving at a value based on an qualitative input of key assumptions. Inputs in Argus do not account for the potential variability of the assumptions.

Current methods include running multiple discounted cash flow scenario’s including an ‘upside’ and ‘downside’ to understand the potentially volatility. This method, while effective in showing returns based on adjustment of inputs, it is not able to deliver a quantitative assessment of risk level reflective of all potential outcomes to compare investments.

Quantitative assessment of risk for investment level decisions is not typical in both an asset level and a portfolio level:

Asset Analysis – Many decisions made on a property level involved some component of uncertainty. Such examples include leasing decisions with credit as a concern, the risk of a termination option, and below market or fixed renewal options. Such key determinants to the value of leases to tenant and landlord are not currently analyzed to take quantitative risk into consideration in providing the landlord perspective on the additional risk such provisions add or reduce risk.

Portfolio Analysis – Investment managers could benefit from understanding of risk and return trade off in construction of portfolios. Portfolio construction does not typically assess quantitative risk of the assets individually compared to the aggregate portfolio. This model can help investment managers select assets that fit the desired risk/return profile of the investor.

Analysis Method

Theoretical Underpinning

To understand Modern Portfolio Theory, it is essential to understand the statistical underpinning of major assumptions. Statisticians have found that naturally occurring data tends to follow a natural distribution (or “Bell Curve”) pattern. The normal distribution has its mean, median and mode as an identical value. This suggests that the mean lies at a point that divides the distribution exactly in half with 50% of the scores lying above the mean and 50% lying below the mean. Since the curve is symmetrical, what holds true on one side of the mean also holds true on the other side. Therefore in the case of a normal distribution, the data becomes easier to analyze by statisticians using the concept of standard deviation of the distribution. The range of scores for a normal distribution of one standard deviation is 34.13% (which holds true on both sides of the mean). This results in that 68.26% of all results under a normal distribution would occur within one standard deviation of the mean. 95.44% of results are within two standard deviations of the mean.

A potential improvement to the existing commercial real estate analytical model is to introduce elements of Modern Portfolio Theory and Post Modern Portfolio Theory. Harry Markowitz’s work in the 1950’s introduced the concept of analyzing expected risk in turn with expected return. Markowitz suggested a mathematical risk/return framework for investment decision making based on the assumption that investors are risk adverse.

MPT is as investment theory that attempts to explain how investors can maximize expected return and minimize expected risk. The theory is a qualitative assessment of the diversification in investing. MPT models a portfolio as a weighted combination of assets so that the return of a portfolio is the weighted combination of the assets’ return. Risk in this situation is the standard deviation of return. By assembling portfolio’s of different assets whose returns are not completely correlated, MPT seeks to reduce the total expected standard deviation, and therefore risk, of the portfolio. MPT also makes the key assumptions that:

‐ Asset returns are normally distributed ‐ Correlations are stable ‐ All investors are rational and risk‐adverse ‐ All investors aim to maximize economic utility

The criticism with MPT surrounds the assumptions that the expected investment performance always fits a normal distribution. Standard deviation analysis and the normal distribution are both limited in the fact that they are symmetrical. Using standard deviation implies that there is an equal chance of a worse than expected 7 Eric Hines Practicum | Johns Hopkins University

return than there is of a better than expected return. Furthermore, using the normal distribution to model the pattern of potential investment returns makes investment results with more upside than downside appear more risky than they really are, with the opposite true as well. This leads to potential for investors to misunderstand the potential ‘upside’ or ‘downside’ of a particular investment when considering only typical MPT methodology.

To take into account these criticisms of MPT, a theory entitled Post‐Modern Portfolio Theory (PMPT) has gained traction among the investment community. PMPT aims to overcome the limitations of MPT by redefining the concept of risk. PMPT recognizes that standard deviation is a poor proxy for investment risk and risk to an investor is the failure to achieve a certain financial goal. In some cases this goal is to completely avoid a loss, sometimes it is tied to a relevant benchmark, for institutional investors it may be to line up assets and liabilities appropriately. PMPT incorporates this redefined sense of risk in a statistical manner by introducing the statistic Downside Risk (DR).

Downside Risk incorporates an investor’s goal and defines risk as those outcomes that do not achieve that goal. The differences between downside risk and standard deviation are that: (1) Downside risk can differentiate between “good” and “bad” results (2) Non‐normal distributions can be analyzed effectively. Downside risk is calculated by downside deviation or the following calculation (where t = target return, r = asset return and f(r)dr = the probability density of r):

The probability density is the likelihood of the specific return to occur on a defined point within the distribution. In the case of this analysis, there are 10,000 results compiled from the Monte Carlo scenario, and the likelihood of each result is thusly 1/10,000.

To integrate return and risk into one statistic, one can use the Sortino Ratio. This statistic is similar to the Sharpe Ratio (which uses standard deviation). The ratio measures how many units of active excess return are expected for ever unit of downside risk. It defines risk in a way that investor’s perceive risk, where the greater the positive value, the better the expected return in relationship to risk. A negative value is a signal that the investment would be a poor choice for the desired benchmark. The ratio is calculated as follows (where T = target return, R = asset return, DR = Downside Risk):

The Sortino ratio statistic provides investors a comparison tool to use as a measuring stick for making decisions between different assets and portfolios on a risk/return basis.

Another measure used by PMPT is Skewness, which the ratio of a distributions’s percentage of total variance from returns above the mean, to the percentage of distributions total variance from returns below the mean. If a distribution is symmetrical, it has a skewness of zero. Values greater than zero indicate positive skewness (slant to values above the mean); values less than zero indicate negative skewness (slant to values below the

mean). The importance of skewness lies in the fact that the more non‐normal a return series is, the more it’s true risk will be distorted by the traditional MPT measures.

Modeling Methods

The simulations will be run with Monte Carlo analysis4 in excel with the help of the Crystal Ball software package. The software applies the Monte Carlo simulation on each of the variables 10,000 times to yield 10,000 expected IRR results. The process takes into account uncertainty of future outcomes and each variable is given a probability distribution based on market data. For example, downtime for a vacant space could be anywhere from 0 to infinity. Everytime a lease rolls over, the space is subject to an uncertainty variable regarding renewal, the tenant either renews or vacates. If the tenant vacates, then the space is subjected to a downtime that is based on a random selection on a number based on the individual probably distribution.

With 10,000 expected IRR results plotted in a distribution, assets can be analyzed for investment by mean IRR as well as risk metrics such as: standard deviation, downside risk and skewness.

Working Model and Results

The model built to analytically review risk and return on an asset and portfolio basis was written in excel and uses the software application Crystal Ball to perform the Monte Carlo simulations. The analysis start date is January 1st, 2010. The portfolio is composed of the following assets:

Suburban Orlando Office Asset – 230,000 SF multi tenanted building built in the late 1990’s. Currently 90% occupied with strong anchor tenants with significant lease term remaining.

Southern New Jersey Industrial Portfolio – 4 building industrial portfolio composed of nearly 1 million SF. Fully occupied with single tenants occupying each of the 4 buildings. Lease term remaining ranges from Q3 2011 to Q3 2014.

Suburban Chicago Neighborhood Retail Center – 138,000 SF neighborhood shopping center anchored by grocer. 40% of the space is occupied by the grocer. The center is 90% occupied.

Suburban Atlanta Neighborhood Retail Center – 88,000 SF neighborhood shopping center anchored by dominant local grocer. 60% of the space is occupied by the grocer. The center is 98% occupied.

Orange County California Office Asset – 75,000 SF multi tenanted building built in the mid 2000’s. Currently 55% occupied.

Northern New Jersey Apartments – 115 unit apartment complex in desirable submarket built in 1990. Currently has 23 units tagged as ‘affordable’ that will be eligible to be converted to market rent in 2011. Unit size ranges from 583 – 1,113 SF.

Uncertainty Variables

4 Monte Carlo methods are useful for analyzing potential outcomes with significant uncertainty in inputs. The greater number of sources of uncertainty, the greater the benefit of this method. Monte Carlo simulations are used in many fields such as: physical sciences, design, and telecommunications. 9 Eric Hines Practicum | Johns Hopkins University

The following are the key assumptions that are subject to uncertainty in the subject properties. See appendix for relevant data sets.

Market Rent Growth – Historical data for each product type and submarket was compiled to create a probability distribution based on the volatility of market rents. Each probability distribution for each submarket was correlated with a growth rate for a specified product type. For example the Orlando office distribution is correlated with the National Office distribution5. Given that each market is subject to different local economic drivers, short term and long term projections take into account supply and demand expectations and well as assumptions that market rents will trend towards replacement cost over the longer term. After the 2‐4 year time horizon, rents are assumed to be stabilized and will follow a long term projection.

Downtime: For the office and industrial assets, a CoStar study was performed to create a downtime data set for each submarket of Class A & B buildings. Data points were also segmented to yield appropriate distributions based on the size of the available vacancy. For retail assets, a study

Downtime Probability Distributions (Data in Months) from 2000 to 2009 of 17 neighborhood/community centers yielded Market Mean Median Range Data Source Orlando Office CoStar downtime data points to create a probability distribution.

Apartment downtime data 7,500 SF + 13.1 11.2 1 ‐ 40 was incorporated with a vacancy allocation based on submarket historical data.

Renewal Assumptions: Each product type was reviewed for renewal rates. For office and industrial, data was

generated from REITS via supplemental reports produced quarterly. The office Renewal Ratio REITS that provided renewal data and were reviewed were: COPT, BDN, HRPT, Data Product Type Ratio Source CLI and MPG. The industrial REITS that provided renewal data and were reviewed Office 60% REITS Industrial 70% REITS were: AMB, DCT, EGP and PLD. Retail data was compiled thru a study of 17 Retail 70% LIM neighborhood / community centers in LIM portfolios from 2000 – 2009.

Expense Growth – Expenses in the model have been broken into: CAM, Real Estate Taxes, Insurance and Utilities. Historical data series of growth rates have been analyzed and fit into probability distribution curves (see Appendix A). The best source of product type data is the BOMA Experience and Exchange Report that specifically reports on office product. The data set gathered from the BOMA Experience and Exchange Report dates back to 1920. The probability distributions for CAM, Real Estate Taxes and Insurance expense growth were all derived from the BOMA data set and used for each of the product types. While not ideal, there is no other applicable data source with an extended history. (Discussion on this topic is included in data limitations heading). The probability distribution for utilities was derived from Bureau of Labor Statistics, which dated back to 1957. At a local level, the Metropolitan Statistical Area’s (MSA) utility data is highly correlated with the national average. See Appendix A for all probability distributions.

Credit Impact – Current analytical methods used to account for potential credit loss are static and do not typically account for the full scope of ramifications of a tenant going Moody's Default Rates Debt Default bankrupt. When a tenant vacates early, the landlord will experience downtime in the Rating Probability space as well as retenanting costs including tenant allowance and leasing commission. AAA 0.00% AA 0.03% Using a monte carlo simulation, the model makes an annual assumption for each tenant A 0.08% BBB 0.24% and the probably of default. Upon an instance of default, downtime will be experienced in BB 0.99% the space along with retenanting costs. Default rates were gathered from Moody’s. B 4.50% CCC 25.67% Tenants with debt ratings were assigned their appropriate annual default rate. Tenants without public debt were all given an assumed BB rating and given an annual default probability based on that rating.

Residual Value –The mathematical method used to arrive at a residual cap Product Type Residual Risk Premium rate is as follows: Expected forward looking 10 Yr Treasury Rate + Risk Market Mean Median Range Premium for Product Type + Age/Obsolesce Premium. Risk Premium uses a Office 2.64% 3.01% ‐14.1% ‐ 21.5% Industrial 2.06% 2.36% 11.9% ‐ 18.0% product specific probability distribution that is correlated with the other Retail 2.26% 2.62% ‐13.5% ‐ 7.3% product types. The risk premium for product type is arrived at by creating a Apartments 1.58% 2.03% ‐6.42 ‐ 3.7% probability distribution of historical data of the difference between going in cap rate and the 10 year treasury rate. The data set analyzed is from 1984 to 2009. The forward looking 10 year treasury rate is derived from using a bootstrapping6 technique on the current yield curve.

Hold Period Maximization – Multiple hold periods were analyzed in generating IRRs. The two periods analyzed are 10 year and 20 year. The 10 year term is consistent with a typical assumed hold period for a core asset and is the standard term length for normal underwriting. A 20 year analysis is completed as well to reduce the impact of the residual cap rate. Assets that have a likelihood of concentrated rollover in a cap year need to be adjusted based on the most realistic sale projection. Taking this into consideration, the maximum IRR is selected for the three years surrounding the target hold period.

Correlations – To fully account for risk, correlations of key variables need to be considered. Market rent growth on a local and national level, expense growth, GDP and inflation are all correlated. See appendix A to see correlation matrix among inputs.

7 Downside risk is based off this investor’s benchmark for the portfolio of a 5% real return. Assuming inflation of 2.5%, the assumed desired outcome is a 7.5% aggregate return. All downside risk calculations in this paper are made with the assumption the investor has a 7.5% target return. 12 Eric Hines Practicum | Johns Hopkins University

‐ Leverage for this portfolio at the existing levels (~30%) adds expected return without sacrificing significant downside risk.

To continue the analysis on a more micro level to gain insight into risk in a variety of scenarios, the results have been analyzed to consider a variety of asset level and portfolio level considerations.

Asset Management Impacts

Termination Option – Tenants with termination options add additional risk to potential returns. The portfolio analyzed has two significant tenants that have termination options written into their leases: 27,000 square feet at the Orlando office property and 198,000 square feet in the Philadelphia Industrial portfolio. Each of these termination options has been modeled into excel with the likelihood of tenant termination dependent upon the tenant’s ability to reduce their rent over the remaining term when taking into consideration the termination penalty. Termination Options % of Eliminating these two options has a positive Termination Termination Remaining Remaining % Chance of Market Date Penalty Obligation Obligation Termination impact for each of these assets. Expected IRRs Philadelphia Industrial 12/31/2010 507,927 2,599,008 19.5% 38.4% for both tenants are flat, however we see a Orlando Office 4/30/2015 51,836 870,242 5.96% 97.7% reduction in downside risk for both assets: Orlando – 7 basis points; Philadelphia – 5 basis points.

The likelihood of a termination is dependent upon market rent fluctuations. Markets with higher rent growth variability are at more risk of these options being exercised then markets with more stable growth patterns. As market rent growth is one of the uncertainty variables in the model, landlords can use this tool to determine how much additional risk and reduction in expected return there is in giving a tenant a termination option.

To analyze the impact of giving termination options to

A sensitivity scenario was run at 50% of the unamortized capital costs as well to gauge the sensitivity of the termination payment (Scenario #2). The portfolio sees a moderately lower expected return and moderate increase in risk. The results on an asset basis are impacted by:

Orlando Office: For Scenario #1 there was a nominal adjustment in expected return and risk. Scenario #2 showed a slight decrease in expected return and increase in risk. Due to the marginal amount of vacancy, the impact on this asset for either scenario is not substantial.

8 San Diego lease length assumption is 7 years and the potential termination would be after year 4. 13 Eric Hines Practicum | Johns Hopkins University

Application of Portfolio Theory to Commercial Real Estate

Chicago Retail: The expected rent volatility of this asset is the lowest among the assets, yielding low probabilities of tenant termination in these hypothetical situations. Also contributing to the minor risk and return movements is the lower amount of capital needed to for release in comparison to office. As shown in the results, there is a minimal impact on risk and return.

San Diego Office: The asset sees the greatest hypothetical impact as the Sortino ratio declined by .05 (Scenario #1) and .16 (Scenario #2). This asset saw the largest impact due to a large amount of vacancy and a volatile market rent assumption.

Conclusions from simulations:

‐ The impact of tenant termination options is fairly significant when applicable to a large amount of space, the asset is in a market with significant rent volatility, and the penalty is less than standard unamortized cost. ‐ When the landlord is adequately compensated (unamortized capital balance) for the termination risk, there is little expected difference in return and risk. ‐ The impact of termination options on expected return and return volatility is based on: amount of capital needed to lease tenant spaces, rent volatility and the negotiated amount of payment tenant is obligated to pay to exercise the option.

Credit Analysis – Historical public debt default rates were gathered from Moody’s and tenants with debt ratings were assigned their appropriate annual default rate in the base scenario. Tenants without public debt were all given an assumed BB rating and assigned an annual default Credit Scenarios probability based on that rating.

Asset managers should not necessarily completely avoid credit risk, as there is a point of potential expected return indifference if the tenant with credit risk is willing to pay a premium rental stream. Accepting a higher rental stream as an offset for credit risk would shift the expected outcome to a higher expected return as an offset for additional risk.

Conclusions: ‐ Credit quality matters, there is a 30 – 40 basis point difference in expected return from moving the credit loss assumption up by 2%. As investment managers underwrite assets, this benchmark can be helpful to gauge appropriate impact to discount rate or required return. 14 Eric Hines Practicum | Johns Hopkins University

‐ An increase in rental rate can offset the impact of credit risk on expected return. Investment managers can use this tool to help negotiate appropriate rental requirements for taking credit risk.

This is especially important to core buyers that are aiming to invest in an asset for stability. ‐ Downtime has a relatively small impact on volatility. Each of the product types all have fairly similar downtime patterns. ‐ Gross lease structures see more expected return volatility than the NNN leased assets. In aggregate, the expense growth projections have a significant impact on expected return volatility. The office and apartment assets have an average of 0.7% standard deviation9 attributed to expense escalation compared to 0.2% for the retail and industrial assets. ‐ Residual Cap Rate assumptions have a large impact on expected returns. The risk premium is most volatile for office and industrial product. Apartments see the lowest volatility in risk premium. Given the magnitude of volatility, it suggests that timing for real estate investors is vital to create strong returns. Investors should look to sell when risk premium is on the low end of the volatility curve, and buy when there is a large spread. Historical data shows this range is approximately ‐4% to 5% with the bulk of the data points falling around 2%‐3%.

Increasing use of debt can be an effective strategy to 2.5 boost expected return. This portfolio is maximized on 2 a risk/return basis at debt levels in the range of 50% ‐ 70%. At the 70%‐80% leverage level, the additional 1.5

return benchmark and the additional downside that 0.5 the leverage creates. 0 Unlev IRR 30% Lev IRR 40% LEV IRR 50% LEV IRR 60% LEV IRR 70% LEV IRR 80% LEV IRR Comparative Asset Types

Office – Returns lags the remainder of asset types, and returns have the highest level of volatility. As a result the Sortino ratio for the office properties lag the remaining assets in the portfolio.

Driving Factors: ‐ Volatile rent growth patterns on the two office assets due to large swings historically in their local markets ‐ Gross leases with narrowing net margins over time as expected expense growth outpaces rent growth ‐ Highest risk premium on resale (thus highest residual cap) of all asset types along with the greatest volatility in risk premium.

Conclusions: ‐ Core buyers looking for return stability should favor other property types. ‐ Given the volatile nature, office can make sense for opportunistic buyers if market is timed correctly. ‐ Market pricing currently for office assets may be too aggressive given the risk. Prices will have to fall to give investors an attractive return for the risk taken.

Apartments‐ Asset return in portfolio is on the lower end for 10 year but stronger under 20 year hold. Expected return volatility (as measured by standard deviation) is the lowest among all of the assets.10

Driving Factors: ‐ Rent growth volatility is lowest among property types. ‐ Apartments have the smallest risk premium on resale ‐ National rent growth is highest for apartments among all property types, leading to less “margin reduction” over time suggesting improved performance over longer hold periods.

Conclusions: ‐ Investors looking for stability should focus on apartments due to the attractive return for every level of risk on long term perspective. ‐ Further analysis is needed to gauge the risk return trade off on apartment assets, as this particular property has unique characteristics that impact expected results.

10 Only one apartment asset was analyzed and is unique in the fact that it has the ability to transform rent controlled units to market rent and is in a highly desired submarket. These two factors have played a role in the assumed “purchase price” and has greater impact on the 10 year hold. 16 Eric Hines Practicum | Johns Hopkins University

Application of Portfolio Theory to Commercial Real Estate

Retail – Strong, well located retail assets have attractive returns with low volatility. The retail assets in this portfolio are attractive on a risk/return basis.

Driving Factors: ‐ NNN leases minimize margin reduction over lease term, helping to reduce return volatility ‐ Minimal capital expenditures for leasing helps minimize risk.

Conclusions: ‐ The assets analyzed are well located, grocery anchored neighborhood centers. This product type provides an excellent return/risk tradeoff. Further analysis would be needed to understand lesser located retail or the mall sector.

Industrial – The industrial portfolio analyzed performs well on a return/risk profile with the second highest expected return and minimal volatility.

Driving factors: ‐ NNN leases minimize margin reduction over lease term, helping to reduce return volatility ‐ Minimal capital expenditures for leasing helps minimize risk. ‐ Higher volatility comes from market rent growth and risk premium.

Conclusions: ‐ With 100% occupancy and low lease rollover until 2013, this portfolio benefits from stable in place dynamics. ‐ With four tenants in the portfolio, credit risk is concentrated. This is typical in warehouse portfolios and focus on credit is thusly more important on a individual tenant basis.

To arrive at this statistic, continuous ten year results were analyzed for each comparative benchmark. The downside deviation is calculated based upon these continuous

10 year results. This method was selected as it gave the best comparison to the expected results in the base portfolio on a 10 year hold basis.

The results show that the portfolio of real estate assets analyzed is efficient from a return/risk basis as compared to NCREIF and the S&P 500. The bond data points showed the lowest risk, while the commercial real estate portfolio’s along with NCREIF were shown to have lower downside volatility compared to the S&P 500.

How this ‘moves the ball forward” and issues

This model creates a tool to analyze commercial real estate decisions on a quantitative basis. Being able to understand both the return and risk profiles from a quantitative perspective will provide another tool in the decision making process. Over the past few decades, real estate has become a more accepted asset class by institutional investors. As many of these institutional investors are looking to line up long term liabilities with long term assets, real estate provides an excellent vehicle to do so. By taking a quantitative look at risk and return, institutional investors can integrate projected real estate risk and return profiles as well as correlation with their stock and bond portfolio’s. Given the ability to understand risk real estate investment managers have the ability to further develop their solicitation of investment capital by showing the benefit of increasing their allocation to direct real estate and the ability of the investor and investment manager to adapt to a desired risk return level based upon how the assets/portfolio is capitalized and managed.

The big issues surrounding the Data Limitations current use of the model are data Market Data Source Date Range Comments Market Rent Growth REIS, TWR 1982 ‐ 2008 Based on asking rents and not achieved rents.

As real estate has increasingly become an accepted investment class over the past decades, data availability has increased, however this provides a minor data set to analyze historical variability.
