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.

Asked about her involvement in her father's statements of financial condition that the judge has already determined fraudulently overvalued his real estate and inflated his net worth, Ivaka Trump said she had no knowledge of them.

"I would assume he had a personal financial statement," Ivanka Trump said. "Those weren't things that I was privy to."

Regarding a lease she had for a penthouse apartment in Trump Park Avenue that included an option to buy for $8.5 million, the New York attorney general's office said Trump's statement financial condition claimed that units in the building were selling for $20.8 million -- two and a half times as much.

Asked by state lawyer Louis Solomon whether she knew about that discrepancy, Ivanka Trump responded, "I wasn't involved in his statement of financial condition so I can't say what it took into account or didn't take into account."

Solomon pressed her about the documents, asking, "Did you know whether he had personal financial statements, Donald J. Trump?" Solomon asked.

"I'm not involved in his personal financial statements. I didn't know about his personal statements, per se, other than what you've showed me," Ivanka Trump responded.

"Did you have any role in preparing Donald J. Trump's statements of financial condition?"

"Not that I'm aware of," she replied.
