It is unclear if the CIO role is new or if Kanter replaces anyone.

Kanter joins ARK from the international law firm Dechert, where she worked for 17 years as a senior partner in the firm's financial services group.

She has also served as vice president and legal counsel at T Rowe Price and worked within the SEC's investment management division.

Overall, Kanter has 30 years of experience advising investment companies, investment advisors, fund boards and broker-dealers. Over the past decade she has focused her practice on exchange-traded funds, private funds and transactional work involving financial service firms.
