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.

The competing obligations between the costs of Donald Trump's 2016 presidential campaign and his business obligations created a "cash crunch" at the Trump Organization that motivated the former president to commit fraud, state attorney Kevin Wallace argued during his summation.

Wallace's theory about the motivation for the alleged fraud, which he articulated for the first time, attempted to explain Trump's motive for the alleged conduct as well as justify levying a fine against Trump in order to regulate the marketplace.

According to Wallace, the hundreds of millions of dollars saved by the Trump Organization through fraud allowed the company to "stay afloat" during a major "cash crunch" during the 2010s.

During the first half of the decade, the Trump Organization spent roughly $775 million to renovate properties including its Doral and Turnberry golf courses, as well as the Old Post Office building in Washington, D.C., Wallace said. The idea that the company could have funded these expenses with cash alone was a "fantasy," according to Wallace.

"By the time you get to 2017, Mr. Trump was becoming president, and the company was getting low on cash," Wallace said. Faced with the chance of a negative cash flow, the company opted to embrace fraud, according to Wallace.

"They didn't have to choose between their priorities," Wallace said about the company's business expenses and Trump's presidential campaign.

Trump attorney Chris Kise objected to the argument, suggesting the theory was nothing more than conjecture -- which prompted a heated exchange with Wallace.

"Chris. Stop. We didn't interrupt the defendants' presentation at all," Wallace shouted while facing Kise.

"I think I agree with Mr. Kise," Judge Engoron responded, but he allowed the presentation to continue.
