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, in a written brief filed a week before the trial's closing arguments, asked the judge in the case to fine Trump over $370 million to disgorge profits from what James says is a decade of fraudulent business conduct, and to bar Trump for life from participating in the New York real estate industry.

The request for a $370 million fine, plus 9% annual interest, is a sharp increase from James' initial request for disgorgement totaling roughly $250 million.

The largest portion of the requested fine stems from the business loans the Trump Organization obtained using allegedly fraudulent financial statements. Based on expert testimony, James argued that Trump cost his lenders $168,040,168, which the banks would have made if Trump was given the appropriate interest rate corresponding to the actual value of his assets.

In their defense filing, Trump's lawyers called the attorney general's theory for disgorgement "fundamentally flawed, saying that "No lenders testified that they would have done anything differently had they known about Trump's misstatements, and James attempted to fill that evidentiary void with expert testimony, according to Trump's lawyers.

Trump's lawyers added that even if the attorney general proved that some of Trump's profits were ill-gotten, they lack the authority under New York Executive Law 63(12) to request the disgorgement.

Closing arguments in the trial are scheduled for Jan. 11.
