RIO DE JANEIRO/SAO PAULO (Reuters) -A group representing minority shareholders on Friday filed a complaint with Brazil's securities regulator against Americanas SA after the retailer uncovered "accounting inconsistencies" totaling 20 billion reais ($3.89 billion).

The Abradin association said it was denouncing Americanas for what it called a "multi-billion fraud," while also asking regulator CVM to investigate the retailer's auditor, PwC.

Shares in Americanas plummeted more than 75% on Thursday, wiping out 8.4 billion reais in market value after the company's chief executive Sergio Rial resigned, citing the discovery of inconsistencies.

"Calling it 'inconsistencies' is nothing more than an attempt to use a euphemism for a multi-billion fraud that not only destroyed the assets of shareholders but also undermined the credibility of Brazil's capital markets," Abradin said in a document seen by Reuters.

Shares in the company were up 19% on Friday.

Americanas did not immediately respond to requests for comment. PwC declined to comment.

CVM had already announced three probes into the retailer. The company, meanwhile, formed an independent committee to investigate.

Directors at the retailer sold around 215 million reais ($42.15 million) in Americanas shares between July and September, according to regulatory filings. Controlling shareholders and members of the board did not sell relevant share volumes.

On Aug. 19, Americanas announced Rial would replace former CEO Miguel Gutierrez after almost 30 years at Americanas in a securities filing.

Rial, in a meeting with investors on Thursday, attributed the inconsistencies to differences in accounting for the financial cost of bank loans and debt with suppliers. Accountants, however, are still trying to figure out details.

"What draws a lot of attention is the size of the problem. It's not easy to hide 20 billion reais," said Eric Barreto, a professor at Sao Paulo's Insper. "If the operations were on the balance sheet, it was a matter of presentation. But I don't know if they were fully on the sheet."

Three Brazilian billionaires who founded 3G Capital have long controlled Americanas. Its stores are ubiquitous at Brazilian shopping malls, and the company's e-commerce unit is one of the country's top online retailers.

Analysts and fund managers are also keenly debating the so-called "inconsistencies."

"The market (including us) still does not fully comprehend what the full implications are for Americanas," analysts at JPMorgan (NYSE:JPM) said in a research note, citing a lack of consistent communication from the company.

Americanas said on Wednesday, when it revealed the matter, that it believed the cash impact of the inconsistencies was not material, although internal inquiries and work by independent auditors was still needed.

Fabio Alperowitch, a manager at FAMA Investimentos, said he had sold his position in Americanas in 2019 due to the "opacity" of its financial statements. "All the evidence of misconduct was there," he tweeted.

"I think this is the biggest scandal I've ever seen on the Brazilian stock exchange," NCH Capital's chief investment officer in Latin America, James Gulbrandsen, said in an interview.

On Friday, ratings agency Fitch downgraded the firm's long-term foreign and local currency Issuer Default Ratings (IDRs) to 'CC' from 'BB'. S&P Global (NYSE:SPGI) also downgraded Americanas' credit rating to 'BB', besides adding it to its CreditWatch list with negative implications.
