A former American Express Co. employee was fined S$24,000 ($19,150) by a Singapore court after he was convicted of misusing client data.

Ricky Suparman, who worked as a corporate sales manager at the U.S. credit card company, copied and e-mailed confidential files to himself in February 2012 before resigning to join a competitor, according to court documents. American Express reported the matter to the Singapore police the following month.

"This ex-employee's access to the office premises and company information was immediately revoked," Sheena Yu, a Singapore-based spokeswoman at American Express, said today in an e-mailed response to questions. "No customer data has been compromised."

The fine comes about four months after Standard Chartered Plc said confidential information on 647 wealthy clients was stolen in Singapore from a printing company. The Monetary Authority of Singapore has taken supervisory actions against the London-based bank, the regulator said in a statement last week, without disclosing details.

Suparman, 27, transferred more than 700 confidential files by copying from a company-issued laptop to his personal flash drive and e-mail addresses from Feb. 17 to Feb. 24, 2012, the court documents show.

He also gained unauthorized access to "hundreds" of confidential financial documents including corporate clients' income statements and details of their signatories, according to court papers. The files were of a "highly sensitive nature" and contained data from American Express's customers from eight countries, prosecutors said.

Suparman didn't immediately reply to two e-mails seeking comment. The Straits Times reported the matter earlier today.

His boss, Belinda Koh, made a complaint to the police on March 2, 2012, alleging he compromised confidential information relating to clients of the New York-based company, which is the world's biggest credit-card issuer by purchases. Suparman didn't manage to use the data as the offenses were discovered before he could do so, according to court papers.

Suparman, who could have been jailed for as long as two years and fined as much as S$5,000 on each of the eight counts, was charged in November 2013 under the Computer Misuse and Cybersecurity Act.

The criminal case is Public Prosecutor v Ricky Suparman. CAD 2-MSC/2013. Singapore State Courts.
