MEASURING TENANT RISKS
BEST BUY CASE STUDY
Best Buy (BBY) once seemed like another victim of internet market share loss:
commodity products, weak store experience, high price competition
Now the company appears to be a “multi-channel” success story, quadrupling the percentage
of its sales from the internet and competing successfully with AMZN
The company managed this transformation with minimal erosion in operating margin,
ongoing competitive occupancy cost ratios, and only a small decline in store footprint

MEASURING TENANT RISKS
SEARS AND MALL PROXIMITY
DDR has low exposure to B-mall and Sears/Kmart shadow supply Most anchors consider
1-2 miles the maximum distance for replacement locations
A greater distance is generally seen as a new store rather than a substitute location

MEASURING TENANT RISKS
OCCUPANCY COST ANALYSIS
Occupancy cost ratios for DDR’s largest tenants have generally fallen over the
last 3 years as tenant sales have outpaced rent growth
Open air occupancy costs are lower than other retail formats

Ross, T.J. Maxx, Burlington and Nordstrom Rack anchor wholly-owned centers comprising 65% of our ABR.
Walmarts, targets, and Costcos that sell food. Nearly as many centers are anchored by traditional or specialty grocers.
DDR’s centers derive roughly one third of their ABR from in-line tenants, even though only 20% of the space is leased to these smaller tenants.17
