The following table illustrates the number of sold or held-for-sale properties included in, or excluded from, discontinued operations:

Properties excluded from discontinued operations	1	13	0	18	32
Total properties sold or classified as held-for-sale	12	38	28	119	197

We allocate interest expense to discontinued operations and have included such interest expense in computing income from discontinued operations. Interest expense allocable to discontinued operations includes interest on any secured debt for properties included in discontinued operations and an allocable share of our consolidated unsecured interest expense for unencumbered properties. The allocation of unsecured interest expense to discontinued operations was based upon the gross book value of the unencumbered real estate assets included in discontinued operations as it related to the total gross book value of our unencumbered real estate assets.
