(CNN) -- Mitt Romney's campaign is shooting down a new Boston Globe report Thursday that claims the former private equity CEO remained at his firm, Bain Capital, for three years longer than he claims.
The newspaper points to documents filed with the Securities and Exchange Commission that state he owned 100% of the company until as late as 2002, though Romney says he left in 1999.
The presumptive GOP presidential nominee maintains he ceded control at Bain in February 1999 in preparation to run the 2002 Winter Olympic Games in Salt Lake City.
The timing of his end-date at the firm remains an important focal point in the presidential race, as Romney argues he left the company before it was involved with the shuttering of certain businesses that led to job losses.
The Boston Globe story on Thursday, however, said "state financial disclosure forms indicate he earned at least $100,000 as a Bain 'executive' in 2001 and 2002, separate from investment earnings."
Documents show, the article stated, that Romney created "five new investment partnerships during that time."
CNN confirmed that an SEC filing from 2001 also lists Romney as the "sole shareholder, sole director, Chief Executive Officer and President of Bain Capital."
Roberta Karmel, a former SEC commissioner who served during President Jimmy Carter's administration, said the documents raise questions about Romney's role at Bain after the GOP contender says he left the company.
"It's a criminal offense to file a false document with the SEC," Karmel said. "And if that isn't true, then he made a false filing, which is something I don't think he wants to claim."
She continued: "If he listed himself and he was getting paid, he was legally responsible."
"Either you're the owner or you're not the owner," Karmel added. "You can't have it both ways."
But Romney's campaign said the Boston Globe article "is not accurate," insisting the candidate left when he says he left.
"As Bain Capital has said, as Governor Romney has said, and as has been confirmed by independent fact checkers multiple times, Governor Romney left Bain Capital in February of 1999 to run the Olympics and had no input on investments or management of companies after that point," Romney spokeswoman Andrea Saul said in a statement.
Responding to questions about the SEC filings, a Romney campaign official said the agency's "regulations are complicated and do not square with common sense in this case."
"Although Governor Romney was not involved with Bain Capital after he left to head the Winter Olympics in 1999, he was still listed on some technical filings," the official said. "This is nothing more than a quirk in the law. When Governor Romney took over the Olympics, he was not involved in the operations of any Bain Capital entity in any way. He was too busy working to make the Olympic Games among the most successful ever held."
The president's re-election campaign, meanwhile, quickly grabbed the Boston Globe report and ran with it Thursday morning, sending out the story to reporters and arguing it was proof that Romney "hasn't been telling the truth" about his exit from Bain.
"This puts him at the center of responsibility for troubling investments involving outsourcing and bankruptcies," said Obama deputy campaign manager Stephanie Cutter in a statement.
Obama's campaign has been calling on Romney to release more than the two years' of tax documents he has already made public, suggesting the candidate may be hiding important details about his finances.
In her statement Thursday, Cutter questioned whether the Romney was concealing his tax documents "because there is still more about this period and beyond that he doesn't want people to know."
"It's time for Mitt Romney to come clean so that the American people can make their own judgments about his record and his motivations," she added.
According to a report last week by Fortune, however, the departure of a private equity firm's ownership structure is "extremely complicated" and it's "reasonable to assume that Romney was considered a 'key man'," at the company, even after he left.
"Each fund's limited partners could have voted to end the fund's investment period - or take over fund management themselves - if a super-majority felt it prudent," the Fortune report stated. "But that didn't happen, and Bain saw no reason to expend massive administrative effort to amend existing funds. Instead, it asked Romney to sign documents when necessary, and made the managerial/ownership changes on new funds going forward."
Further, the non-partisan group FactCheck.org stood by its previous analysis, saying there is not enough evidence to show that Romney was still managing Bain, even part-time, during his time at the Olympics.
"We would reassess our judgment should somebody come up with evidence that Romney took part in any specific management decision or had any active role (not just a title) at Bain after he left to head the Olympics," said Brooks Jackson, the director of FactCheck.org.
He added: "But in our considered judgment, nothing in the Globe story directly contradicts Romney's statements - which he has certified as true under pain of federal prosecution - that he 'has not had any active role' with Bain or 'been involved in the operations' of Bain since then."
