The media-measurement firm comScore has had a shakeup at the top levels of its management team. Variety reports that as the company undergoes an internal accounting review that has stalled its financial reporting, comScore announced that co-founder Gian Fulgoni will take on the role of CEO and that CFO Mel Wesley is departing the company.

“With Fulgoni’s appointment, previous CEO Serge Matta will become executive vice chairman and adviser to the chief executive officer,” Variety reports. “David Chemerow, a former Rentrak exec who was chief revenue officer since comScore’s acquisition of Rentrak in January 2016, is taking over as CFO.”

Variety adds: “The company also announced that Joan Lewis, a former Procter & Gamble exec, has been elected chair of the comScore board of directors. That comes after comScore co-founder Magid Abraham last month resigned as executive chairman of comScore; he will remain on the board through the remainder of his term, which expires in 2018.”
