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.

Testifying about the preparation of the Trump Organization's statements of financial condition in 2011, former Mazars USA accountant Donald Bender said Trump executives largely provided the input data for statements, in addition to dictating the standards by which the work was completed.

"We would cut and paste that information into a new worksheet," Bender said about the approach taken by Mazar after receiving new data from co-defendant Jeffrey McConney of the Trump Organization.

When asked about the compliance with the Generally Accepted Accounting Principles -- which Bender testified are the standards for accounting in the United States -- Bender repeatedly placed responsibility in the lap of the Trump organization.

"That was the Trump Organization's responsibility," Bender testified about GAAP compliance.

Bender acknowledged that he rarely questioned the inputs from the Trump Organization, and when he did, he largely dealt with McConney and executives other than Trump and his adult sons.

Repeatedly asked by the state attorney if Mazars would have issued the statements if they had known the Trump Organization included material misrepresentations in their data, Bender reiterated that Mazars would not have issued the statements.

When Judge Engoron remarked at the end of the trial day that the state would still need to present further evidence to prove that the 2011 statement was within the statute of limitations, Trump seized the statement as a partial victory.

"The last five minutes was outstanding, because the judge actually conceded that the statute of limitations … is in effect," Trump told reporters as he was leaving court.

Engoron, however, did not completely rule out the 2011 evidence during trial, instead appearing to remind counsel that they need to show the 2011 statement represents an ongoing concern that falls within the statute of limitations.

Testimony is scheduled to resume on Tuesday at 10 a.m. ET.
