Crudely, IPMS3 does not include service cores but does include the pillars and is measured to the window. This accounts for the 3% or 4%. The OPW negotiates a price, directly or through its agents, with the owner or landlord based on net lettable area, effectively divided by the number of square feet, to come up with a per square foot area, and then multiplies this by the bigger area, which is IPMS3, thus giving a higher rent. Is this correct? Is that what happened?
