Former President Donald Trump and New York Attorney General Letitia James, in separate media appearances, addressed the ruling Friday evening, trading barbs while reacting to the judgment.

Speaking from his Mar-a-Lago estate in Florida, Trump said he had to pay a fine for "having built a perfect company." Accusing both James and Judge Arthur Engoron of being politically motivated, Trump denied committing any fraud and said he plans to appeal.

Meanwhile, in New York, James lauded the ruling as a victory for all Americans and the principles of equal justice under the law -- saying "former presidents are no exception."

"The scale and scope of Donald Trump's fraud is staggering -- and so, too, is his ego and his belief that the rules don't apply to him," she said.

James also heralded Judge Engoron's penalties as effective remedies to "ensure this fraud cannot continue."

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.

Court was adjourned for the day following an afternoon in which Judge Engoron appeared to shoot down one of the defense's main remaining arguments following defense attorneys' request for a directed verdict.

Defense lawyer Chris Kise argued that the state failed to prove that Trump's lenders would have acted differently had they known about the fraud alleged by the New York attorney general -- but Engoron said "the mere fact that the lenders were happy doesn't mean the statute wasn't violated."

Earlier this month, during testimony from the defense's first expert witness Steven Witkoff, Trump's lawyers attempted to argue that Trump had undervalued some of his properties, which balanced out the alleged inflated properties in his statement of financial condition. Engoron, however, declined to allow testimony related to that argument, saying, "The reader of the financial statement has the right to know whether each particular number was accurate."

That same day, Trump's lawyers also presented testimony from expert witness Jason Flemmons that Trump disclosed that the values of nearly 95% of the assets in his financial statements departed from generally accepted accounting practices.

"It's effectively saying, 'User beware,'" Flemmons said.

But Engoron said Flemmons only addressed the methods used in the statements, rather than the numbers themselves, which could have been incorrect.

Defense attorneys are scheduled to call additional witnesses over the next week before Eric Trump and Donald Trump return to the stand as the defense wraps up its case in the next two weeks.
