Former acting CFO Steven Mahr has left the city of Chicago's finance team. "The market saw his appointment as a continuation of the very measured, thoughtful, reasonably transparent debt management that had been happening when Jill Jaworski was CFO." And I think (Mahr) deserves a lot of credit for that." White has served the city as debt manager for three years after serving as a senior fiscal policy analyst for six years. The city spokesperson confirmed that White will be interim CFO as the city conducts a search process.
