Teen-clothing chain

Aeropostale

(ARO)

fired its chief merchandising officer after finding that he concealed an affiliation with a major vendor.

Christopher Finazzo was fired for cause, effective immediately, the retailer said Wednesday.

Chairman and CEO Julian Geiger will fill the role until a replacement is found.

According to the company, an investigation revealed that Finazzo hid personal ownerships in and served as an officer of entities affiliated with one of the company's primary vendors, South Bay Apparel.

"Mr. Finazzo's actions are unacceptable," said Geiger in a press release. "Aeropostale does not tolerate any noncompliance with its Code of Business Conduct and Ethics. While painful, our decision was swift, comprehensive, and consistent with the highest standards of corporate governance and ethics."

Aeropostale said the probe will be concluded prior to the early December filing of its third-quarter report, and it doesn't expect the matter to affect earnings.
