WASHINGTON -- Anheuser-Busch InBev will pay $6 million to settle charges by U.S. regulators that it paid off government officials in India to boost sales and production, then tried to quiet an employee who raised the issue.

A joint venture in which Anheuser-Busch InBev had a 49 per cent interest used third-party sales promoters to make payments to Indian officials in violation of the Foreign Corrupt Practices Act, the Securities and Exchange Commission said Wednesday.

The law is typically used to prevent bribery.

Anheuser-Busch InBev must, for two years, co-operate with the SEC and notify some former employees that they are not prohibited from contacting the SEC about possible violations, according to the settlement.

Anheuser-Busch InBev entered into a separation agreement with the whistleblowing employee that included non-disclosure and a "substantial financial penalty" for violating the agreement, according to the SEC.

Despite repeated complaints from employees, the company, now based in Leuven, Belgium, had inadequate internal accounting controls to detect and prevent the payments, the SEC said.

"Anheuser-Busch InBev recorded improper payments by its sales promoters in India as legitimate expenses in its financial accounting, and then exacerbated the problem by including language in a separation agreement that chilled an employee from communicating with the SEC," said Kara Brockmeyer, chief of the SEC Enforcement Division's FCPA Unit.

Anheuser-Busch InBev said in a company release that the violations came several years before it began independent operations in India in 2015, and that it subsequently trained its Indian employees on compliance.

The settlement arrived on the same day that SABMiller, which makes Fosters and Miller beer, announced its shareholders had approved a $103 billion takeover byAnheuser-Busch InBev.

Shareholder approval was the last major hurdle in a deal that will give the combined company control of almost a third of the global beer market.

The takeover is expected to be formally completed next month.
