Metropolitan Chicago Market Review Office Market Review Second Quarter 213

To our valued customers, partners and future clients A powerful storm blew through Chicago on a late afternoon about a month ago called a derecho, it packed some vicious straight-line winds and sheets of rain. From my office window in suburban Oakbrook Terrace, I had a clear view west down I-88. I saw the clouds gather and the sky darken. It rolled quickly down the corridor and enveloped my building. While the storm was in full effect, traffic below slowed to a crawl and windshield wipers couldn t keep up. Almost everyone who was caught outside got off the streets. Those who didn t huddled in doorways, heads down. The storm was gone as quickly as it arrived, traffic picked up and people made their way back outside. The economic derecho that hit commercial real estate in 28 has certainly taken a while longer to blow over, but there are some similarities. As you ll see in the following pages, traffic has picked up and we ve clearly moved from a head-down attitude. National and global economics remain in flux in many cases, but local conditions in Chicago and in many US markets reflect optimism. Our brokers and property managers see it firsthand in the markets we live and work in every day. On the industrial side in particular, we ve seen an impressive stretch of 12 straight quarters of positive absorption. For the first time in five years, new construction is significantly underway. Office growth has been on a steady climb, with suburban and downtown absorption neck-and-neck over the past two years. The second quarter of 213 saw a temporary slow-down in the suburbs, but signs are pointing toward a strong second half across the entire Chicago market. With this edition of our market review, our research team is implementing a new design to deliver even more information in a clear, concise package. We hope you find it to be a valuable resource in the coming months. Please always bear in mind that this document is a representation of our expertise, and our research and brokerage professionals are always willing to assist with any of your real estate needs or inquiries.

Foreign Policy Magazine recently ranked Chicago sixth among world competition, measuring econometrics from the number of Fortune 5 companies to the fl ow of goods and services through airports and ports. Situated at the geographical heart of the nation, Chicago s locational advantages have fostered its development into an international center for banking, securities, high technology, air transportation, business services, wholesale and retail trade, and manufacturing. In addition, Chicago is one of the principal trading centers for commodities, fi nancial, and derivative futures products with the Chicago Mercantile Exchange and Board of Trade. Quarter in Review We re now entering into the fi fth year of recovery from one of the deepest economic recessions the country has historically seen and while we re still not fl ying high, we ve certainly come a long way. Many economists predicted an even more anemic recovery than what has transpired. The expectations of a double-dip recession didn t come true. When the next recession arrives, and it eventually will, enough time will have passed that it won t be a double-dip. Others predicted delinquencies and defaults in commercial real estate to be the next downfall of the economy. This also didn t happen.

assets picked up, returning the commercial real estate world to a more normal state. The housing market was expected to recover much more slowly as well, due to homeowners putting their homes on the market at the fi rst sign of increasing prices, resulting in high inventory levels. Inventories, however, remain well below expectations and the housing market has quickly rebounded, though still has a long way to go. U.S. Business Confidence 7 Local Economy Real GDP continues to grow, rising at a rate of 1.7% during the second quarter, and has returned to record levels 3% higher than before the recession. This suggests that, in terms of GDP, the economy has recovered everything lost in the recession and them some. However, when placed alongside the 4-year GDP trend line, the U.S. economy is still well behind where it should be, and at the current rate of growth, that gap continues to widen every year. 6 5 4 3 26 27 28 29 21 211 212 13 Source: Tradingeconomics.com, Institute for Supply Management Job growth is still a major conversation, and Chicago continues to lag the rest of the country. Nationwide, more than 72% of the nearly 9 million jobs lost due to the recession have been regained through hiring, but only 5% of the jobs lost in the Chicago metropolitan area have been recovered. The job recovery has been focused in larger cities, with some cities posting a very robust recovery, such as Houston recovering 241% of the jobs lost due to the recession with a relatively healthy 6.3% unemployment rate and New York City regaining 197% of the jobs lost due to recession. Washington, D.C. is experiencing an impressive 5.3% unemployment rate, and has recovered 165% of the jobs lost. Hiring continues to expand, with 65% of industries adding workers, suggesting the job recovery is broad, but still relatively shallow. Until 75% of the jobs lost are recovered, companies are just fi lling offi ce desks that were vacated during the recession. Other positive signs continue to point towards a growing economy. Consumer confi dence recently rose to a fi ve-year high, a signal that consumers are starting to see a brighter future. The housing market continues to recover. The dramatic increase in home prices in some markets has been due to a lack of inventory and fewer housing starts than expected. However, there has recently been a 5% increase in singlefamily housing starts. Despite this good news, growth will still be held back by state and local fi scal woes until some of the deadlock can be resolved. Nationally, government spending now accounts for 23.5% of the economy, while revenue collection accounts for only 15.7%, the largest gap the country has historically seen.

Quarter in Review For the fi rst time in nearly two years, net absorption turned slightly negative in the suburban offi ce market during the second quarter, totaling negative 1,148 SF. While the suburban market absorbed more space than the downtown market for the past year, that trend ended during the second quarter, as demand for space picked up downtown and sizable new vacancies were added to the market in the suburbs. The largest new vacancy introduced during the quarter was caused by ACCO Brands leaving the 175,645 SF building located at 3 Tower Pky in the Lincolnshire Corporate Center for 189,92 SF in the Kemper Lakes Business Center in Long Grove. The suburban offi ce vacancy rate remained unchanged from last quarter at 2.29%. Despite the fl at conditions during the second quarter, leasing activity remain elevated and investment sales activity continued to pick up. Net absorption for the fi rst half of the year remains postive at 36,41 SF of vacant space absorbed, and the current vacancy rate is still more than 1.2% below the rate recorded a year ago and nearly 3.4% the peak rate recorded in late 21.

With an unparalleled, qualifi ed workforce, the north suburbs also lay claim to Chicago s popular North Shore communities where many of the area s chief executives and advisors choose to reside. In previous years, the market has fallen victim to large reductions in size from companies such as Allstate and Hewitt & Associates, but historically the market has been better served by its pharmaceutical-related staples including Walgreens, Baxter and Abbott Laboratories.

North Suburban Quarter in Review Net absorption turned negative during the second quarter, strongly infl uenced by the departure of ACCO Brands world headquarters from its 175,545 SF building in the Lincolnshire Corporate Center for 189,92 SF in the Kemper Lakes Business Center in Long Grove. While this departure was anticipated, it was signifi cant enough to offset the effects of continued leasing activity, resulting in an absorption tally for the second quarter totaling negative 115,678 SF. Responding accordingly, the North Surburban vacancy rate increased by 38 basis points, to close the second quarter at 17.62%; yet this rate is still more than 1.2% below the rate recorded a year ago. Pharmaceutical company AbbVie, a recent spin-off of Abbott Laboratories, signed the largest new lease of the quarter, taking 49,173 SF at 75 N Fairway Dr in Vernon Hills Continental Executive Park. The lease brings the 189,686 SF building to 1% leased. Cloud-based solutions provider BigMachines, Inc. expanded its lease at 57 Lake Cook Rd in Deerfi eld by an additional 18,177 SF, bring its total in the building to 51,988 SF. Looking Forward Despite a setback during the second quarter, the overall trend in the North Suburban market continues to be positive. There remain plenty of options for tenants large and small in the area, with nine blocks of contiguous space 1, SF or larger currently available. Investment sale activity continues to strengthen and will continue to do so over the coming quarters, as the former Kraft Campus in Glenview went under contract during the second quarter. Illinois Tool Works has agreed to purchase the 5, SF facility from Hamilton Partners.

Recently, big companies such as Catamaran Corporation and Capital One have leased signifi cant space in the submarket. The area had been plagued with overall negative absorption and elevated vacancy rates since 26, in part due to area mortgage companies giving back space in excess of one million SF. However, market conditions have fi nally started to improve in the Northwest Suburban market over the past several quarters.

Northwest Suburban Quarter in Review Net absorption was effectively fl at for the second quarter, following fi ve quarters of positive absorption. Continued leasing activity was offset by new vacancies being introduced to the market, the largest of which involved APP Pharmaceuticals Inc relocating its operations to Kemper Lakes Business Center in Long Grove and putting its 63,499 SF space in the Schaumburg Corporate Center up for sublease. The vacancy rate was unchanged during the second quarter at 22.44%. A joint venture between GlenStar Properties and Walton Street Capital acquired the 58% leased four-building offi ce complex known as Continental Towers in Rolling Meadows during the second quarter. The transaction was a REO sale, and traded for $58.5 million, or about $64. PSF. The buyers plan to invest in the complex to reposition the buildings as premier class A assets for their market. The largest lease signed during the second quarter involved credit card company Capital One Financial Corp. taking an additional 67,599 SF in the Atrium Corporate Center in Rolling Meadows. Capital One had leased 15, SF in the building last year, and will now occupy 217,599 SF, bringing the building to nearly 1% occupancy. Looking Forward Investment interest in the Northwest Suburban market should continue to pick up, evidenced by the two-building Century Centre offi ce complex being listed for sale during the second quarter. Despite fl at conditions during the second quarter, the overall trend in the Northwest Suburban market will continue to be positive as demand increases due to the economic recovery and blocks of vacant space are absorbed.

Due to its central location, proximity to O Hare International Airport and access to public transportation, the O Hare submarket has led the suburban offi ce recovery. Many companies have identifi ed the O Hare submarket as the ideal location for a new offi ce or a consolidation of multiple locations. Geographically, O Hare sits in the center of the major suburban submarkets providing the middle ground for employees coming from surrounding locations, not to mention immediate access to the airport for multi-market companies. Additionally, O Hare is the only submarket providing access to the CTA s elevated train lines from the city, allowing convenient public transportation for city-dwelling staff members.

O Hare Area Quarter in Review New vacancies pushed net absorption negative during the second quarter, totaling negative 21,752 SF. Although several new leases were signed and tenants took occupancy of recently leased space, these new vacancies outweighed the positive effects of this leasing activity. The largest vacancy introduced to the market during the second quarter was in the east tower of Triangle Plaza, where Verizon moved out of its 72,362 SF space. The O Hare vacancy rate increased by 14 basis points to end the quarter at 2.48%. The American Academy of Orthopaedic Surgeons broke ground on a new fi ve-story 165, SF build-to-suit headquarters during the second quarter, one of two new construction projects in the O Hare Area market since 21. The new building will be located at the corner of River and Higgins Roads, less than two blocks from its current location. The Big Ten Conference is also under construction on a 5, SF headquarters building in Rosemont that will include an interactive sports museum. Leasing activity was limited to spaces smaller than 2, SF during the second quarter. No signifi cant sales activity was recorded during the quarter. Looking Forward Many of the O Hare Area s premier buildings that had languished during the recession have seen lots of new transaction activity during the recovery. These buildings have signifi cantly increased their occupancy levels and have lead the improvement trend witnessed throughout the market. This has resulted in landlords pushing rental rates and reducing concession packages amongst these higher-end properties. This tightening of options among the market s premier buildings is beginning to translate to demand for the area s class B buildings and will continue to do so over the next two years.

Split into western and eastern sections by I-355, the western half of the market consists of relatively new product and the majority of the larger blocks of space. Historically home to large technological users including Alcatel-Lucent and Tellabs, Inc. and other sizeable corporations such as Navistar and BP Amoco, the western half of the market is more prone to sudden changes in vacancy and absorption. The characteristically more stable eastern section is defi ned by more diverse multi-tenant buildings, smaller blocks of space, and older product.

East-West Corridor Quarter in Review The East-West Corridor vacancy rate was largely unchanged during the second quarter, decreasing slightly to 21.7% from last quarter s 21.11%. While this is signifi cantly below the 23.77% peak vacancy rate witnessed in mid-21, vacancy has leveled off over the past year, experiencing only minor fl uctuations. Net absorption for the second quarter totaled 15,41 SF, as new vacancies offset the effects of continued leasing activity. The largest new vacancy is the result of Waste Management leaving 46,382 SF in the Executive Towers West II building at 1411 Opus Pl in Downers Grove, relocating into its recently expanded space at Butterfi eld Centre in Lombard. The largest investment sale transaction involved Transwestern Investment Management LLC acquiring the 299,792 SF twobuilding offi ce campus in Downers Grove known as The Corridors in an auction sale for only $22.9 million, or about $76 PSF. Adding the buyer s premium pushes the total price to just over $8 PSF. At the time of sale, the buildings were only 51 percent leased and had been through multiple ownership changes. However, the fully-leased 184,17 SF building located at 21 York Rd in Oak Brook, sold for $34 million, or about $185 PSF, showing that investors are willing to pay a premium for well-leased buildings. The largest lease of the second quarter involved Wells Fargo Home Mortgage expanding into 67,175 SF at One Imperial Place in Lombard. Looking Forward Large blocks of vacant space are getting more scarce, especially on the eastern side of the East-West Corridor and rental rates have already begun to increase in the area s best buildings. Several companies have signed leases over 4, SF over the past two years, helping to accelerate the recovery in the East-West Corridor. This trend is expected to moderately continue, further diminishing the inventory of quality available space.

Growth in the I-55 Corridor market is tied to the rapid growth of Will County.

I-55 Corridor Quarter in Review The I-55 Corridor vacancy rate experienced a signifi cant adjustment during the second quarter due to 112,957 SF being absorbed through new leases being signed. While in most larger offi ce markets, that amount of absorption would result in a less signifi cant correction, due to the small size of the I-55 Corridor, it was enough to drop the vacancy rate by 2.81% to 13.29% by the end of the quarter. Two leases were signed at 5 Joliet Rd in Willowbrook, resulting in 78,4 SF of vacant space being removed from the market. HVAC, refrigeration and welding technical school Environmental Technical Institute leased 48,923 SF, while structural engineering and architecture fi rm Raths, Raths & Johnson, Inc. leased the remaining 29,477 SF, bringing the building to 1% occupied. The largest sale of the second quarter involved Deutsch Bank & Wealth Management, formerly known as RREEF Real Estate, buying the two-story,,233 SF offi ce building at 22 Heritage Pky in Woodridge for $13.3 million. The building is fully-leased to Allstate Corp. and last sold in 23 for $17.1 million. Looking Forward The I-55 Corridor will continue to be dictated by tenants leasing space and new vacancies being introduced to the market. Due to the small size of the I-55 Corridor market, these new vacancies and new leases can have a signifi cant impact on the area s vacancy rate, as demonstrated during the second quarter. The area remains an affordable alternative to parts of the East-West Corridor and will continue to attract tenants based on value and its transportational and locational advantages.

Quarter in Review The recovery of the downtown offi ce market continued unabated during the second quarter, as 398,58 SF of vacant space was absorbed through new leases and tenants expanding. This activity pushed the overall vacancy rate down 29 basis points to 13.%, the lowest level witnessed in the downtown offi ce market since the end of 28, and a rate 14 basis points better than a year ago, and more than 4% the peak rate recorded in mid-21. The Central Loop and East Loop submarkets posted the greatest demand during the second quarter, absorbing 249,47 SF and 195,561 SF respectively. Net absorption turned negative and the vacancy rate rose slightly in both the North Michigan Avenue and River North submarkets, while the West Loop saw relatively fl at conditions due to new vacancies reducing the positive effects of continued leasing activity. The largest new lease signed during the second quarter involved Google leasing 223,67 SF in the 689,67 SF building to be known as 1KFulton, which is currently under construction in the Fulton Market area of the West Loop.

Wacker Drive lies at the heart of the submarket and has been the corridor of the most signifi cant offi ce developments. After several years of no construction cranes in the submarket, new development activity has begun again, with two buildings under construction at 444 W Lake St and 1 W Fulton St totaling 1,55,67 SF and a 4, SF building at 2 W Randolph St close to being approved. Several additional offi ce buildings have been proposed in the West Loop submarket, including a nearly 1.5 million SF offi ce tower at 4 W Randolph St. Vacancy Absorption 4, 2, 2% 18% Vacancy by Class Type 12.76% 12.96% -2, 16% 14% 6.4% -4, 12% -6, 28 29 21 211 (%) 212 13 1% Net Absorption (SF) Class A Class B Class C Direct Vacancy Sublease Vacancy 22 NAI Hiffman Two buildings are currently underway in the West Loop, with another soon to break ground, the most activity seen in years

West Loop Quarter in Review The West Loop vacancy rate was fl at during the second quarter when compared to last quarter, dipping only 3 basis points to 12.25% as net absorption totaled 12,91 SF for the three month period. While leasing activity continued unabated, several new vacancies combined to negate the positive effects of the elevated demand that has been commonplace in the submarket for the past three years. Investment sale activity continued through the second quarter, with the largest sale involving the 65,812 class A offi ce tower located at 225 W Wacker Dr being purchased by South Korean investment fi rm Mirae Asset Global Investments LLC for $218 million, or about $335. PSF. Foreign investment fi rms are becoming increasingly interested in Chicago buildings as prices soar in premier offi ce markets like New York and San Francisco. The largest new lease signed during the second quarter involved technology giant Google leasing 223,67 SF in the under construction offi ce redevelopment project being called 1K Fulton at 1 W Fulton St. The company will be moving more than 5 employees from River North to the new offi ces once they are complete. Looking Forward Construction continues on the downtown market s newest offi ce tower known as River Point at 444 W Lake St. The building will be 45 stories and will offer 861, SF of space. However, prominent developer J. Paul Beitler is pushing hard to start construction on a 23-story offi ce building at 2 W Randolph offering 4, SF of offi ce space that he hopes will be delivered in 215, before River Point is completed. The West Loop will continue to experience elevated demand due to its proximity to various transportation options and class A product.

While this distinction has faded over the decades, several banks still remain and it has become a central hub for many local and national law fi rms. Chicago s El train serves the submarket well, as the area is surrounded by the trains loop. Unlike many of the West Loop s more modern and well-equipped structures, buildings in the Central Loop tend to be older with smaller fl oor plates and less in-building parking.

Central Loop Quarter in Review The Central Loop vacancy rate decreased by 63 basis points, as 249,47 SF of vacant space was absorbed through new leases being signed and tenants taking occupancy of recently leased space. New vacancies were few during the second quarter when compared to the fi rst quarter, when the City of Chicago departed 124,875 SF at 33 N La Salle St, resulting in a period of negative net absorption for the submarket. The absorption tally for the fi rst half of the year totals 23,843 SF, and the area s vacancy rate has improved to a level nearly 1.5% a year ago. Two offi ce towers sold during the second quarter, the larger of which involved CBRE Global Investors buying the 5-story, 936,683 SF building located at 181 W Madison St for about $3 million, which last sold for $2 million in 26. CBRE Global Investors also agreed to sell the 798,782 SF offi ce tower at 1 S LaSalle St for about $211 million. Both sales are indicative of a downtown offi ce investment sales market that has strongly rebounded. Minneapolis-based U.S. Bank expanded its lease at 1 S LaSalle St by an additional 43,37 SF and secured naming rights during the second quarter, bringing its total space in the building to about 11, SF. Looking Forward Investment sales look to remain active in the Central Loop submarket over the coming quarter, as two buildings are currently under contract including a joint venture between John Buck Co. and Korean investors planning to buy the 1.1 million SF offi ce tower at 161 N Clark and a private investor under contract to buy the 226,666 SF building at 32 W Randolph. Leasing activity has been consistently elevated and has pushed the vacancy rate back to 28 levels. This trend is also expected to continue as 4 contiguous blocks 2, SF or larger in size remain available.

Over the past several years, the submarket has benefi ted from a plethora of condo conversion projects that have rejuvenated the area and its aging buildings. However, since the economic downturn, the market for condo conversions has been greatly diminished. The area does not benefi t from the easy access to highways or commuter lines that neighboring submarkets enjoy, but it is still within walking distance of the El trains, Millennium Park and close to Lake Shore Drive.

East Loop Quarter in Review Several new leases were signed during the second quarter, resulting in 195,561 SF of vacant space being absorbed and an 82 basis point drop in the East Loop vacancy rate to end the quarter at 15.16%. This is the lowest vacancy rate witnessed in the East Loop submarket since late 28 when the economic recession was taking hold. Through the fi rst half of the year, net absorption has totaled 223,53 SF. Although no buildings sold during the second quarter, an investment group led by Mark Karasick of 61W Companies and Michael Silberberg or Berkley Properties, in partnership with long-term owner BentleyForbes, are investing more than $1 million to re-capitalize the two Prudential Plaza offi ce towers. New York-based Am Trust Realty Corp. is under contract to buy the 526,158 SF offi ce building at 1 E Wacker Dr in a sale-leaseback transaction expected to close this fall. The building has never changed ownership since it was built in 1962. The largest lease was signed by the American Management Association, taking 5, SF at 33 E Wacker Dr. Looking Forward The East Loop has now witnessed three consecutive quarters of improving conditions, suggesting that demand is picking up in the submarket and a steady improvement trend may fi nally be establishing itself. The recovery has been uneven due to periods of large vacancies, such as Groupon leaving 22, SF at 33 E Wacker Dr, have been followed by periods of signifi cant leasing activity, resulting in large swings in absorption. Only four blocks of space 1, SF remain available, suggesting that there are fewer opportunity for these big swings going forward.

A distinguished retail corridor interspersed with posh residential towers, North Michigan Avenue is a Chicago icon renowned throughout the world. The offi ce submarket consists of primarily smaller-sized spaces. The submarket is home to Northwestern Memorial Hospital and the new home of the Lurie Children s Hospital of Chicago. The presence of these large healthcare institutions should benefi t the submarket for years to come.

North Michigan Avenue Quarter in Review Net absorption was slightly negative during the second quarter, totaling negative 14,976 SF due to several new vacancies, the largest of which involved long-term tenant Energy BBDO leaving 58,298 SF behind with its move to 225 N Michigan Ave in the nearby East Loop submarket. The vacancy rate increase by 12 basis points to 17.19% at the end of the second quarter, a level slightly above the 16.4% rate recorded a year ago, but still below the peak 18.3% reached in late-211. A group of investors including The Hearn Co., The Lynd Co. and Mount Kellett Capital Management L.P. purchased the offi ce and parking portions of the landmark John Hancock Center in June for $14 million as part of an REO sale. The purchase included fl oors 4-41 of the 1-story building, with the offi ce sector comprising 856, SF in addition to building s parking facilities and several common areas. The largest lease signed during the second quarter involved employee assistance program-provider ComPsych Corporation renewing its existing lease and expanding by an additional 23,471 SF in the NBC Tower. Looking Forward Six options for 1, SF of contiguous space remain available in the North Michigan Avenue submarket. Until some of these large blocks of space begin to lease, signifi cant improvement is unlikely. While the small size of the submarket suggests that appreciable fl uctuations in the vacancy rate can occur, transaction velocity is also typically slow in the area. Two new medical offi ce buildings are planned near Northwestern Memorial Hospital. The hospital plans to construct a 24-story, 993, SF outpatient pavilion that is anticipated to be completed in fall 214. A new hospital for the Rehabilitation Institute of Chicago is planned for the vacant site at the northwest corner of Ontario St and McClurg St, with completion anticipated for 216.

The recent construction in the neighborhood of high-end residential developments, retail and up-scale restaurants has also been of note, but only one available development site remains at Wolf Point where the Chicago river splits, so major new offi ce developments will be rare. The submarket is the least accessible to transportation of all the downtown offi ce submarkets, but offers sensational views along the Chicago River. Several highprofi le, quickly-growing companies have decided to call River North home, including tech giant Google, Inc and deal-of-theday website company Groupon.

River North Quarter in Review The River North vacancy rate increased by 33 basis points during the second quarter due to several new vacancies and limited new leasing activity resulting in negative 44,7 SF of net absorption. Although transaction velocity was relatively quiet during the second quarter, the fi rst quarter witnessed several new leases and lease expansions signed, resulting in signifi cant positive absorption. Therefore, the tally for the fi rst half of the year remains positive, totaling 75,524 SF of vacant space absorbed. The largest sale of the second quarter involved Chicago-based investment and real estate development fi rm Brijus Capital, LLC buying the 112,6 SF offi ce loft buildings at 357 & 363 W Erie St for $8.5 million. At the time of the sale, the buildings were about half empty, but the buyer plans to invest $4 million to $5 million to upgrade the buildings and draw new creative and technology-oriented tenants. Google s recent acquisition of Motorola Mobility, leasing 572, SF in the Merchandise Mart last year, signed a lease during the second quarter to expand into an additional 32, SF in the iconic 4 million SF building. Looking Forward The River North submarket has been ground zero for the recent surge of tech companies moving into Chicago. The hope is that this trend continues. However, few large contiguous spaces remain available for these companies to move into. The signifi cant improvement trend witnessed over the past year should continue, but at a slower pace as smaller spaces are leased.

Methodology & Definitions Methodology The information included in this review is the result of a compilation and analysis of data from various sources on class A, class B and class C industrial properties located in the metropolitan Chicago area defined by the submarket map on the previous page. NAI Hiffman obtained the information from property representatives, CoStar Group, RealCapital Analytics, industry periodicals and magazines, our in-house property database, and other sources. NAI Hiffman greatly appreciates the participation of each of these individuals, companies and resources, without whose help this report would not have been possible. All of the information detailed throughout this report is saved and organized in our own in-house database and is regularly updated. Utilizing this database, we can analyze, calculate and report demographic information, inventory, vacancy, availability, net absorption, and transactional information. Definitions The NAI Hiffman Market Reviews track several measures of market conditions. This information is collected for individual properties then consolidated, organized and analyzed for submarket and market totals. These terms, used throughout the reports, are defined below according to NAIOP Terms & Definitions. Net Absorption The net change in occupied space in a given market between the current measurement period and the last measurement period. Net absorption can be either positive or negative and must include decreases as well as increases in inventory levels. For the purpose of this report, sublease space is included in the calculation of net absorption. New Supply The total inventory delivered to the market since the last measurement period. Delivered is defined as total square footage and/or number of buildings that has completed construction and received a certificate of occupancy during a stated period. Under Construction Buildings where either: a) actual ground breaking has occurred (site excavation or foundation work) and construction is ongoing (not abandoned or discontinued) but for which a certificate of occupancy has not yet been issued; or b) properties undergoing conversion to office from another use or c) properties undergoing a major renovation where 75 percent or more of the building is not available for lease and building generally requires a certificate of occupancy to be made available for lease. Total Inventory (Market Size) The total square footage of gross rentable area in a specific market. It includes the gross rentable area in buildings that have received a certificate of occupancy. Total inventory increases when a new building is delivered and decreases when an existing building is destroyed, demolished or its use changes. Available Space The total amount of space that is currently being marketed as available for lease in a given time period. It includes space that is available, regardless of whether the space is vacant, occupied, available for sublease, or available at a future date. Available space excludes shadow space.
