NEW YORK — Raghav Khanna has been appointed to Aleris International Inc.’s board by the aluminum company’s parent following the resignation of Kenneth Liang last week.

Aleris parent company Oaktree Capital Management LP, Los Angeles, appointed Khanna to Aleris’ board after Liang resigned Dec. 5. Liang’s departure was not due to any disagreement with the board or the company, according to a filing with the U.S. Securities and Exchange Commission (SEC).

Khanna currently serves as vice president in the opportunities funds of Oaktree Capital Management and is responsible for deal execution, trade strategy and portfolio management. He joined Oaktree earlier this year after previously working as an associate at Carlyle Group in New York and as an analyst at Goldman Sachs Group Inc. in New York and London.

The board substitution comes nine months after the Beachwood, Ohio-based company surprised investors by delaying its planned initial public offering.

Aleris still has its S-1 Form needed for the public offering on file with the SEC, a company spokeswoman said, declining to comment further on the details.
