Hansen Natural Corp. said it found no wrongdoing during an internal probe into its stock options practices and plans to file its earnings by May 14.

A special committee found some errors in accounting for options and inadequate accounting and administering processes, but no “willful or intentional misconduct” by any company executives, the company announced.

The Nasdaq Stock Exchange set the May deadline after threatening several times to delist the Corona company when Hansen failed to file any earnings reports for the past six months, citing the ongoing investigation for the delay.

At issue were 12,000 grants Hansen said it “inadvertently” issued to an unnamed outside director in November 2004, four months after that options plan had expired.

Last fall, the U.S. Securities and Exchange Commission requested documents and information on stock options awarded to Hansen employees dating back to 1996.

Shares in Hansen were 19 cents to $36.40 in afternoon trading Monday on the Nasdaq.
