Supplement to case W16664.

On June 9, 2011, Empresas La Polar S.A., a Chilean retailer, informed the Chile's securities commission that it had detected irregularities in its accounting for credit card receivables. A fraudulent credit card scheme masterminded by key executives and missed by directors and auditors was going to result in an estimated write-off in excess of US$300 million. On June 17th, the company advised the commission that the write-off would, in fact, be double the original estimate, amounting to US$640 million, resulting in negative equity. The filing contributed to a decrease in the value of the company's stock market value, dropping from US$1.2 billion to US$281 million and putting the company at risk of bankruptcy. Should the directors be held responsible and punished for what had happened? What role did the regulators and auditors play?
