My market has a Simon mall and they don't have their name anywhere on the exterior even after some renovations were done in the past decade, but it is on some signs, security policies, etc. inside the mall.
When they market the mall which isn't much sometimes the marketing messages mention that it is a Simon property but other times they don't mention it. Any retailer who advertises and says they are located at the mall, simply refers to the mall's name, never includes Simon in their location information (in verbal ads, print ads, when they answer the phone, website locators, etc.). Westfield seemed to want their name to be used steadily.... at every turn (or every example like I just cited) when the mall was being referenced. Ego much?
