Centennial Bank Office Portfolio Stratifications Likely suspects: Class B, Suburban, Low rise, multiple building parks Property Size # Outstanding ($MM) $/SF Less than 20,000 SF 282 $185 $98 20,000-50,000 SF 53 $104 $67 50,000-100,000 SF 15 $101 $100 Over 100,000 SF 13 $245 $53 TOTALS 363 $635 $70 While class is a largely subjective measure, we largely consider over half of our portfolio to be Class B, followed closely by Class A. Location is equally split between CBD and Suburban locations. A large majority of our space is Low rise (considered to be 1-3 floors). Property size is on both ends of the scale with over 75% in number below 20,000 SF, but in $ outstanding, nearly 40% was above 100,000 SF. This is largely multiple building properties, rather than large single buildings, as noted by the low number of High Rise properties.
