129662Erin Callan, who served as Lehman's chief financial officer until she was ousted in June, is saying goodbye to 15 Central Park West. According to the WSJ, she's selling her condo for $11.8 million, just below the asking price of $12 million. Callan made a tidy profit: She agreed to pay $6.48 million for the apartment three years ago—back when the building was under construction—although she only closed on the purchase in April, which is when she first put it on the market for $14 million. One unusual footnote to the story: The 2,400-square-foot apartment is located on the 31st floor, the same floor she occupied when she worked at Lehman.
