Coca Cola has received subpoenas from an Atlanta grand jury, the company announced last week.

On Friday, Coke issued a regulatory filing announcing the news. The subpoenas are a result of an ongoing investigation by the Securities and Exchange Commission (SEC) into accusations made by a former employee, Matthew Whitley, who accused the company last year of inflating earnings.

The company also said that it has provided documents and materials regarding the case to the attorney's office as part of an informal request.

In May last year, Whitley filed a lawsuit against Coke, alleging that he was laid off for being a "whistleblower." Whitley has since withdrawn the suit after settling with Coke, but the SEC and Atlanta's US Attorney have been investigating the claims.

Coke has denied the wrongdoings.
