Malaysia's troubled wealth fund 1MDB has revealed that Deloitte told it in February it would quit as auditor as soon as a replacement could be found.
The fund's announcement came in the wake of last week's move by the U.S. Department of Justice to seize more than $1 billion worth of assets it alleged were tied to an international conspiracy to launder money funneled away from 1MDB.
As well as giving notice of Deloitte's intention to resign as auditor of the fund, 1MDB said in a statement posted on its website on Tuesday that it "remains confident" that the fund committed no wrongdoing and that previous audited statements were "true and fair."
But it added that as "a precautionary measure," the 2013 and 2014 audited statements shouldn't be relied on until the allegations in the U.S. complaint were resolved.
Deloitte echoed that view, saying in a statement dated Tuesday that if the information in the U.S. complaint had been known during the 2013 and 2014 audits, it would have impacted the financial statements and audit reports Deloitte signed off on for those years.
The accountancy firm added that 1MDB hadn't yet informed Deloitte Malaysia that it had appointed any new auditor.
Three of the Big Four accounting firms appeared to have walked away from their work at 1MDB.
In February 2014, the Malaysian fund issued a statement saying that it "mutually agreed with KPMG that the firm would cease to be 1MDB's auditors" and that Deloitte would take over the role.
The statement at the time said KPMG had signed off on the 2010, 2011 and 2012 accounts, but that Deloitte would complete the audit for the financial year ended March 31, 2013. 1MDB said that it had received an extension until the end of March of 2014 to file those annual statements.
The 1MDB statement from February 2014 added, "this is nothing special or new as it is in line with best market practice where companies decide on its current or future auditors after considering all aspects, including but not limited to conflict of interests and other consideration."
According to a Wall Street Journal report on Tuesday, however, the Malaysian auditor general found in 2015 that Malaysian Prime Minister Najib Razak, who chaired 1MDB's board of advisers, had fired KPMG at the end of 2013 for balking at approving the fund's accounts.
KPMG didn't immediately return an emailed request from CNBC for comment.
Multiple media reports had said that EY, another Big Four firm, which was the auditor for 1MDB and its predecessor fund from 2009-2010, had also been sacked by the wealth fund in 2010 after also raising concerns over the accounts. EY didn't immediately return an emailed request for comment.
