Senior leadership changes at the Municipal Securities Rulemaking Board (MSRB) under new CEO Mark Kim include the transition of the organization’s chief compliance officer to the role of chief regulatory officer.

Gail Marshall will move forward as regulatory chief after previously holding the title on an interim basis while also serving as CCO. Marshall has shed her CCO title, and no replacement for her at the position was named.

In the chief regulatory officer role, Marshall will lead the MSRB’s rulemaking activities, professional qualifications program, compliance initiatives, and examination and enforcement support—all tasks similar to what a CCO would be responsible for. She will receive support from Omar Ahmed, who is staying on as chief risk officer at the MSRB and will oversee the organization’s enterprise risk management and strategic planning.

Other executive changes include Nanette Lawson assuming the chief operating officer position in addition to her prior role as chief financial officer and treasurer and Brian Anthony being promoted to chief data officer responsible for advancing the MSRB’s data strategy.

“From my first day on the job as CEO, I knew that the MSRB already had a strong team in place to carry out our important work to protect investors, issuers and the public interest,” said Kim, who took over as CEO in October, in a press release. “I could not be more proud and excited to announce the leadership team that will partner with me to serve the needs of our evolving market.”

The MSRB’s vacant general counsel position remains unfilled. Former Board Member and Chief Legal Officer Robert Fippinger and Deputy General Counsel Jacob Lesser will continue to fill the role on an interim basis.
