Along with the portfolio additions, EOP is hiring 106 former Spieker employees -- nearly 100% of the field personnel that managed buildings in the region. Spieker's Lynda Clarke and Scott Coombs will handle overall management duties for EOP in Portland and Seattle, respectively.

In the Greater Seattle area, EOP's 10.4 million sf is spread amongst 64 buildings. In the Portland area, its 3.8 million sf equates to 42 buildings. In Seattle, the EOP's highest concentration is in Downtown Bellevue, where it owns just over 50% of the office space. In Portland, it's easily Kruse Way, a high-rent suburban submarket just a few miles south of Portland on the east side of Interstate 5 wherein Spieker holds at least an 80% market share for class A office space.

As a result, says Pat Callahan, EOP's Northwest regional director, more than ever the company has a diverse array of space options for its clients. "If a tenant has to grow, contract or relocate, at any given moment we can make that happen," said Callahan during a conference call with the media. "A single asset landlord can't do that."
