(CHICAGO, IL, Aug. 30, 2005) National occupancy levels for both suburban and downtown office properties in operation for 12 months or more rose slightly in 2004 from the prior year. Occupancy levels for suburban office properties rose two percent to 97 percent, whereas those for downtown office properties rose just one percent to 96 percent. Rental rates, overall operating costs and net operating income remained relatively stable across the sector last year, as did overall operating costs.

These are among the key findings reported in the 2005 edition of the Income/Expense Analysis®: Office Buildings, a new benchmarking study published by the Institute of Real Estate Management (IREM®). This annual research study, conducted by IREM® since 1976, analyzes operating income and costs for nearly 2,500 private-sector buildings across the United States. It is designed to help property owners, managers, investors, appraisers, lenders, developers and other real estate professionals evaluate their buildings' performance and prepare budget and revenue projections, feasibility studies, etc.

SUBURBAN COLLECTIONS RISE SLIGHTLY, DOWNTOWN COLLECTIONS DIP
During 2004, total collections for suburban office complexes nationwide increased 0.8 percent from 2003 levels to $18.34 per square foot of net rentable area, whereas downtown properties decreased 3.5 percent to $18.50 per square foot. Total actual collections by downtown properties were 0.9 percent more last year than their suburban counterparts.

OPERATING COSTS ESSENTIALLY SAME AS 2003
Total operating costs for suburban buildings in 2004 rose 0.4 percent from the prior year to $7.65 per square foot, while operating costs for downtown properties declined just 0.2 percent to $8.82 per square foot of rentable area.

Nationally, net operating costs for suburban buildings increased 0.9 percent to $5.56 per square foot in 2004 as compared to 2003, whereas net operating costs for downtown properties rose 0.3 percent to $6.32 per square foot.

KEY EXPENSE COMPARISONS
Except for insurance costs, which dipped 0.9 percent, all major expense categories for suburban properties increased slightly from the prior year. Utility costs saw the largest increase, 5.9 percent, followed by administrative/benefits costs, up 2.8 percent, janitorial/maintenance cost, up 0.5 percent, and real estate and other taxes, up 2.3 percent.

In contrast, buildings in downtown markets saw either a minor rise or dip in each expense category except for utility costs, which remained exactly the same as in 2003. Administrative/benefits costs increased 3.5 percent, real estate and other taxes declined 2.4 percent, janitorial/maintenance costs declined 3.3 percent and insurance services dipped 3.2 percent from the prior year.

Focusing again on major expense categories, but as a percentage of total operating costs, the IREM® study reveals that suburban properties spent 25.5 percent of their operating budget on janitorial/maintenance services, 23.6 on utility costs, 23.5 percent on real estate and other taxes, 14.3 percent on administrative/benefits and 14 percent on insurance/services. Similarly, expenditures for janitorial/maintenance services accounted for the largest chunk of downtown property' operating budgets, 26.4 percent, followed by 23.4 percent spent on real estate and other taxes, 20 percent spent on utilities, 13.7 percent spent on insurance/services, and 13.3 percent spent on administrative/benefits.

Overall, suburban properties proved 13.3 percent less costly to operate in 2004 than their downtown counterparts, as all expense categories for suburban properties, except for utilities, were less than those experienced by downtown buildings.

MEDIAN OPERATING RATIOS
Though downtown properties reported higher total actual collections than suburban properties, the overall operating experience of both downtown and suburban office markets were similar as indicated by their median operating ratio (net operating costs divided by total actual collections). The median operating ratio at suburban properties was 0.30 while the operating ratio at downtown properties was 0.34.
