Lew Pearlson has returned to State Street Global Advisors after an 18-month stint as director of investor relations at hedge fund Sowood Capital Management. Toby Seggerman, head of client service for nonprofits, said Pearlson's position was created in response to the growth in SSgA's nonprofit business.

Pearlson worked for SSgA between 2000 and 2004, and Seggerman thinks he returned because "he missed the culture, he missed the camaraderie." Pearlson declined to comment. At Sowood, he reported to Megan Kelleher, partner, who has taken on his responsibilities until a replacement is hired.
