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 executives courted Donald Trump to attract more business and referrals, viewing the former president as an opportunity to sell services to his family members and other high-net-worth individuals, according to the testimony of former Deutsche Bank managing director Rosemary Vrablic.

"Given the circles this family travels in, we expect to be introduced to the wealthiest people on the planet," Vrablic wrote to colleagues while courting Trump in the early 2010s, according to materials entered into evidence.

Recruiting Trump stemmed from a 2007 effort in the bank to develop a broader commercial real estate financing division for their high-net-worth individuals.

"He would have fit the category of the entrepreneur and investor with a successful track record," Vrablic testified on the stand regarding Trump's profile.

After being introduced to Donald Trump Jr. through Ivanka Trump's now-husband Jared Kushner, Vrablic began pursuing Donald Trump's business.

"We are whale hunting ... Haven't seen him yet. Also maybe Dad will convert like Ivanka did," Vrablic wrote in a 2011 email to a colleague.

"It is a term used when there is a very high-net-worth individual who is a prospect," Vrablic said in explaining why she referred to Trump as a "whale."

Once Trump was on board, leadership from the bank personally courted Trump to do more business with the bank and to connect them to other potential clients. The former CEO of the bank personally met with Trump with the express goal of gaining more deposits from Trump and leveraging Trump's relationships.

CEO Anshu Jain "thought that if Mr. Trump wanted to, there could be additional leverage provided among his world," Vrablic testified.

The effort appeared to work, as the bank made over $3 million in revenue from Trump in 2013, up from only $13,000 in 2011.
