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.

Deutsche Bank's $378 million in loans to the Trump Organization was a "good credit decision," the bank's former risk management executive told the court at the end of more than a day of testimony.

"I think we did a reasonably thorough analysis of the information," former Deutsche Bank executive Nicholas Haigh testified under cross-examination by the defense.

An internal Deutsche Bank group evaluated Trump's financial information, personally visited Trump Organization offices to review bank and brokerage records, and conducted some appraisals of property explicitly used as collateral, according to Haigh.

Though the value that Deutsche Bank determined for the properties often differed by hundreds of millions of dollars compared to the Trump-provided value, the entities continued to have what internal bank documents described as a "long and satisfactory relationship."

"Using a Deutsche Bank-adjusted value for the assets, the net worth still exceeded $2.5 billion," Haigh said, referring to Trump's net worth as it related to a loan covenant.

When Trump decided to run for president and won the election, Deutsche Bank was supportive of the business relationship, though management was careful to monitor their particularly high-profile client, according to internal bank documents presented at trial.

"Note that the relationship continues to be monitored at the highest levels of senior management within the firm and any issues arising from the Guarantor's status as President of the United States are immediately addressed, taken to the appropriate Reputation Risk committee, and discussed with appropriate legal counsel," a credit report said.

When asked directly if the decision to work with Trump was a "good credit decision" by defense attorney Clifford Robert, Haigh responded, "I generally agree with that."

During redirect questioning, state attorney Kevin Wallace stopped short of directly asking Haigh if he would have still done business with Trump had he known about the inflated value of Trump's assets. But he asked Haigh whether Trump's financial information could have been incomplete.

"You have no way of knowing if there was information that wasn't provided to you?" Wallace asked.

"That is correct," Haigh said, marking the end of his questioning.
