Based on Friday's decision, former President Trump and his co-defendants will likely owe $463.9 million based on their initial fine and the prejudgment interest imposed by the court, according to a representative for the New York attorney general.

Trump himself will likely owe $453.5 million, between his $354.86 million fine and $98.6 million in interest.

The amount of interest owed by the defendants is set to increase every day they do not pay the fines.

New York Attorney General Letitia James, whose office brought the civil fraud case against Donald Trump, described the ruling as a "tremendous victory for this state, this nation, and for everyone who believes that we all must play by the same rules -- even former presidents."

“When powerful people cheat to get better loans, it comes at the expense of honest and hardworking people," James said in a statement. "Everyday Americans cannot lie to a bank to get a mortgage to buy a home, and if they did, our government would throw the book at them. There simply cannot be different rules for different people."

The former president is "finally facing accountability for his lying, cheating, and staggering fraud," she said.

In addition to the fines imposed on Donald Trump and his co-defendants, the judge's decision leaves the Trump Organization in a constrained position to continue operating their New York-based businesses.

While Judge Engoron backtracked on his September summary judgment ruling -- vacating the part of his order that canceled their business certificates -- Donald Trump and his sons are temporarily unable to lead their namesake company. Trump faces a three-year ban on serving as the leader of a New York company, and his sons face two-year bans.

An independent monitor will continue to oversee the company's finances for at least three years, and the company needs to install a director of compliance.

Regarding the combined $364 million owed by the defendants, experts who ABC News spoke with believe it is unlikely any of them foot the bill immediately; instead, they can cover the fine with a bond while they appeal.

On Michael Cohen, Donald Trump's former lawyer and self-described "fixer," Judge Engoron wrote in his ruling that he found the star witness to be a credible witness despite having been convicted of perjury.

"His testimony was significantly compromised by his having pleaded guilty to perjury and by some seeming contradictions in what he said at trial," Engoron wrote. "However, carefully parsed, he testified that although Donald Trump did not expressly direct him to reverse engineer financial statements, he ordered him to do so indirectly, in his 'mob voice.'"

Engoron continued that although the "animosity between the witness and the defendant is palpable, providing Cohen with an incentive to lie, the Court found his testimony credible, based on the relaxed manner in which he testified, the general plausibility of his statements, and, most importantly, the way his testimony was corroborated by other trial evidence."

A "less-forgiving factfinder" might have come to a different conclusion and not believed "a single word of a convicted perjurer," Engoron wrote.

"This factfinder does not believe that pleading guilty to perjury means that you can never tell the truth," he continued. "Michael Cohen told the truth."

Cohen, who pleaded guilty in 2018 to lying to Congress about the Russia probe, addressed the passage on social media, writing on X, "Judge Engoron's determination regarding my veracity at the NYAG Trump civil fraud trial. Michael Cohen told the truth!"

Trump Organization executive Patrick Birney testified that then-CFO Allen Weisselberg told him that Trump wanted to see his net worth "go up."

"Did Allen Weisselberg ever tell you that Mr. Trump wanted his net worth on the statement of financial condition to go up?" state attorney Eric Haren asked Birney.

"Yes," Birney said. "I think that happened in Allen Weisselberg's office."

Birney said the meeting with Weisselberg happened sometime between 2017 and 2019, but could recall a specific date.

The testimony prompted a quick objection from Trump attorney Chris Kise, who pushed back on claims from the New York attorney general that there was a conspiracy between Trump Organization employees to inflate Trump’s net worth.

"They are mixing hearsay and the conspiracy," Kise argued.

Judge Engoron asked both parties to submit two-page memos by tomorrow about whether the statements from Birney are hearsay.

Trump's lawyers declined to cross-examine Birney, who stepped down from the stand, clearing the way for Trump Hotels chief accounting officer Mark Hawthorn to testify.
