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.

New York Attorney General Letitia James is requesting a forensic review of Trump Organization electronic data after identifying a missing set of emails between former CFO Allen Weisselberg and a real estate executive.

"The failure to produce these later emails indicates a breakdown somewhere in the process of preserving, collecting, reviewing and producing documents," state attorney Kevin Wallace wrote in a letter to Judge Arthur Engoron.

The request follows an accusation from Forbes Magazine, reported in a story last week, that Weisselberg committed perjury on the stand, based on "old emails and notes, some of which the attorney general's office does not possess." Despite Weisselberg testifying that he "never focused on the apartment," the Forbes story said that he "played a key role in trying to convince Forbes over the course of several years that it was worth more than it really was."

The letter from the attorney general appears to focus on an email exchange related to the value of Trump's golf courses, rather than the value of his Trump Tower penthouse at the center of the Forbes accusations.

"We would therefore propose that the Monitor undertake a forensic examination of electronic data held by the Trump Organization for the very brief period August to September of 2016 to determine if all responsive information has been produced," Wallace wrote.

While Weisselberg's testimony concluded last Thursday, both parties have reserved the right to call the former Trump Organization CFO back to the stand.
