Washington Prime Group has 28 department store boxes in our Tier One and Open Air portfolio which we believe will need to be repositioned. This includes Sears, other than those owned by Seritage, and Bon-Ton department stores. Of the 28 locations, we own all but three spaces, and we are currently in various stages of planning and negotiations to replace or redevelop 23 of these locations. To put this into perspective, revenue derived from the aforementioned 28 boxes equates to only 1.7% of total annualized revenue for the combined Tier One and Open Air portfolio.
“In closing, status quo is not acceptable. The late musician Frank Zappa stated ‘without deviation from the norm, progress is not possible’. I wholeheartedly embrace this notion of ‘thinking outside the box’ and the newfound corporate culture of Washington Prime Group reflects this ideal as we continue to grind it out.”
