A new report from the failed crypto exchange FTX’s current leadership says that former FTX US President Brett Harrisonresigned last Septemberpartly because of a “protracted disagreement” with CEO Sam Bankman-Fried andmembers of his inner circle.

Thereport, filed Sunday with the U.S. bankruptcy court in Delaware, is FTX CEO John J. Ray III’s first detailed account of the control failures at the exchange since he took over after its spectacular collapse last November.

Harrison, according to the report, had serious concerns about the way FTX US was being run, including “the lack of appropriate delegation of authority, formal management structure and key hires.”

When he took those concerns to Bankman-Fried and Nishad Singh, former director of engineering, his bonus was “drastically reduced” and he was instructed by company lawyers to apologize to Bankman-Fried, according to the report. He refused.

The allegations are consistent with Harrison’searlier statements, made via Twitter, that he was threatened after making a written complaint in April 2022, and told that he would be fired and that “Sam would destroy my professional reputation” if he didn’t retract the complaint and deliver an apology.

Reached Sunday by CoinDesk, Harrison confirmed the report but declined to comment further.

According to the report, another employee in the exchange’s legal department was “summarily terminated after expressing concerns about Alameda’s lack of corporate controls, capable leadership and risk management.”

Over 45 pages, Ray’s report paints a picture of FTX and related entities as a sloppily run web of companies ruled over by Bankman-Fried and his circle of cronies, who cared little for organization or internal controls.

Reconstructing FTX’s balance sheets has been “an ongoing, bottom-up exercise that continues to require significant effort by professionals,” partly because FTX’s leadership regularly lost track of accounts and didn’t bother to cash checks, which “collected like junk mail,” according to the report.

Alameda wasn’t even clear on what its own positions were, “let alone hedging or accounting for them,” the document reads. A June 2022 portfolio summary, which was supposed to show Alameda’s makeup of crypto positions, was reportedly fabricated after employees were allegedly instructed by an unnamed higher-up to “come up with some numbers? Idk.”

At one point, according to the report, Bankman-Fried told employees:

“Alameda is unauditable. I don’t mean this in the sense of ‘a major accounting firm would have reservations about auditing it’; I mean this in the sense of ‘we are only able to ballpark what its balances are, let alone something like a comprehensive transaction history.’ We sometimes find $50m of assets lying around that we lost track of; such is life.”

Bankman-Fried’s internal admissions to his employees often directly contradicted his public statements, made either via Twitter or to the press.

For example, Bankman-Fried preached the importance of two-factor authentication to his Twitter followers, writing “Daily reminder: use 2FA! 90% of crypto security is making sure you’ve done the basics.”

But according to Ray’s report, FTX failed to use two-factor authentication for its critical corporate services, including Google Workspace and 1Password. Other security issues included storing seed phrases and private keys to various hot wallets containing hundreds of millions of dollars worth of cryptocurrency in plain text and without encryption on an FTX Group server.

According to Ray’s report, FTX held the vast majority of its crypto assets in hot wallets at all times, despite Bankman-Fried’s public reassurances that the exchange used a “best practice hot wallet and cold wallet standard solution for the custody of virtual assets.”
