Morningstar Inc. announced Monday that its chief operating officer, Tao Huang is leaving the company at the end of the month.

The Chicago-based company said that Huang, 48, will continue to serve as a management advisor to the firm.

In addition to serving as COO, he is responsible for information technology, corporate sales, and Logical Information Machines, which Morningstar bought in 2009.

Morningstar said that it does not plan to name a new chief operating officer. Information technology will report to Joe Mansueto, chairman and chief executive officer of Morningstar; corporate sales will report to Scott Cooley, chief financial officer; and Logical Information Machines will become part of Morningstar's data division, led by Elizabeth Kirscher.

Mansueto said in a press release that Huang led the development of many of the company’s “major software offerings and played a lead role in growing our international business and making acquisitions.”

Huang, who has been Morningstar’s chief operating officer since 2000, said he wants “try other challenges in my business life not related to this industry, and the team is now in place that can make my departure seamless to the organization.”

Huang has worked at Morningstar since 1990, when he was hired as a software developer. From 1996 to 1998, he served as chief technology officer. From 1998 to 2000, he served as senior vice president of business development and head of international operations.
