M&T Bank in Buffalo, N.Y., has expanded the job responsibilities of René Jones, its chief financial officer and vice chairman, while at the same time naming a new CFO.

Jones will be given oversight of two business lines at the $124 million-asset company, mortgage and consumer lending, while retaining oversight of treasury and Wilmington Trust, according to a Wednesday news release. The new roles will take effect May 2.

Jones will drop his CFO title and retain the title of vice chairman. He will not be given a new title, according to an M&T spokesman.

Jones, 51, joined M&T in 1992 and was promoted to CFO in 2005. He was named vice chairman in January 2014.

Jones has led M&T's conference call discussions with analysts over the past several quarters. Many of those discussions revolved around issues tied to M&T's long-delayed acquisition of Hudson City Bancorp, and M&T's efforts to improve its anti-money-laundering compliance functions to gain regulatory approval for the deal.

“René has helped guide M&T successfully through one of the most challenging 10-year periods in our company's history,” Robert Wilmers, M&T's chairman and chief executive, said in the release.

Wilmers, 81, has been chairman and CEO for more than 30 years. M&T's president and chief operating officer, Mark Czarnecki, in August began treatment for pancreatic cancer. Czarnecki has remained in his roles at M&T.

Also on Wednesday, M&T promoted Darren King to succeed Jones as CFO. King, 47, is currently head of the bank's retail and business banking division. He began working for M&T in 2000.
