Reuters: Time Warner Cable said chief financial officer Arthur Minson would step down effective immediately, less than a week after Charter Communications agreed to buy the company for $56 billion. Minson, 44, will join startup WeWork as president and chief operating officer, but will remain as an adviser to Time Warner Cable until the Charter transaction closes. WeWork, started in 2010, provides creative office and meeting spaces for professionals. Minson, popularly known as Artie, was a deputy chief financial officer at Time Warner Cable from 2007 to 2009. He returned to the company in 2013 after a stint at AOL, where he was its CFO and chief operating officer.
