Question: Winston Groom was to receive what percentage of the film's net profit?
About the article "Forrest Gump", section "Author controversy".

Candidate passages:
Winston Groom was paid $350,000 for the screenplay rights to his novel "Forrest Gump" and was contracted for a 3 percent share of the film's net profits.
However, Paramount and the film's producers did not pay him, using Hollywood accounting to posit that the blockbuster film lost money.
Tom Hanks, by contrast, contracted for the film's gross receipts instead of a salary, and he and director Zemeckis each received $40 million.
Additionally, Groom was not mentioned once in any of the film's six Oscar-winner speeches.
The dispute was later resolved.
Profit margin, net margin, net profit margin or net profit ratio all refer to a measure of profitability.
It is calculated by finding the net profit as a percentage of the revenue.formula_1 where Net Profit = Revenue - Cost Profit margin is calculated with selling price (or revenue) taken as base times 100.
Profit margin is the percentage of selling price that turned into profit, where as "Profit Percentage" or "Markup" is the percentage of cost price that one gets as profit on top of cost price.
While selling something one should know what percentage of profit will he get on a particular investment so companies calculate profit percentage to check what is ratio of profit on the basis of cost.
The profit margin is mostly used for internal comparison.
It is difficult to accurately compare the net profit ratio for different entities.
Individual businesses' operating and financing arrangements vary so much that different entities are bound to have different levels of expenditure, so that comparison of one with another can have little meaning.
A low profit margin indicates a low margin of safety: higher risk that a decline in sales will erase profits and result in a net loss, or a negative margin.
Profit margin is an indicator of a company's pricing strategies and how well it controls costs.
Differences in competitive strategy and product mix cause the profit margin to vary among different companies. 
In accounting, gross profit or sales profit is the difference between revenue and the cost of making a product or providing a service, before deducting overhead, payroll, taxation, and interest payments.
Note that this is different from operating profit (earnings before interest and taxes).
The various deductions (and their corresponding metrics) leading from Net sales to Net income are as follow: Net sales = Gross sales – (Customer Discounts, Returns, Allowances) Gross profit = Net sales – Cost of goods sold Gross profit percentage = {(Net sales – Cost of goods sold)/Net sales} x 100 Operating Profit = Gross Profit – Total operating expenses Net income (or Net profit) = Operating Profit – taxes – interest  
Winston Groom's price for the screenplay rights to his novel "Forrest Gump" included a 3% share of the profits; however, due to Hollywood accounting, the film's commercial success was converted into a net loss, and Groom received only $350,000 for the rights and an additional $250,000 from the studio.
Stan Lee, co-creator of the character Spider-Man, had a contract awarding him 10% of the net profits of anything based on his characters.
The movie "Spider-Man" (2002) made more than $800 million in revenue, but the producers claim that it did not make any profit as defined in Lee's contract, and Lee received nothing.
He has filed a lawsuit against Marvel Comics.
The estate of Jim Garrison sued Warner Bros. for their share of the profits from the movie "JFK" (1991), which was based on Garrison's book "On the Trail of the Assassins".
The case was settled in 1999, with Garrison's estate receiving a "very small settlement.
"Art Buchwald received a settlement after his lawsuit "Buchwald v. Paramount" over Paramount's use of Hollywood accounting.
The court found Paramount's actions "unconscionable", noting that it was impossible to believe that a movie (1988's Eddie Murphy comedy "Coming to America") which grossed US$350 million failed to make a profit, especially since the actual production costs were less than a tenth of that.
Paramount settled for an undisclosed sum, rather than have its accounting methods closely scrutinized.
The 2002 film "My Big Fat Greek Wedding" was considered hugely successful for an independent film, yet according to the studio, the film lost money.
Accordingly, the cast (with the exception of Nia Vardalos who had a separate deal) sued the studio for their part of the profits.
The original producers of the film have sued Gold Circle Films due to Hollywood accounting practices because the studio has claimed the film, which cost less than $6 million to make and made over $350 million at the box office, lost $20 million.
Hollywood accounting is not limited to movies.
An example is the Warner Bros. television series "Babylon 5" created by J. Michael Straczynski.
Straczynski, who wrote 90% of the episodes in addition to producing the show, would receive a generous cut of profits if not for Hollywood accounting.
The series, which was profitable in each of its five seasons from 1993–1998, has garnered more than US$1 billion for Warner Bros., most recently US$500 million in DVD sales alone.
But in the last profit statement given to Straczynski, Warner Bros. claimed the property was $80 million in debt.
"Basically," says Straczynski, "by the terms of my contract, if a set on a WB movie burns down in Botswana, they can charge it against "B5" profits.
"Peter Jackson, director of "The Lord of the Rings", and his studio Wingnut Films, brought a lawsuit against New Line Cinema after "an audit... on part of the income of "The Fellowship of the Ring".
Jackson stated this is regarding "certain accounting practices", which may be a reference to Hollywood accounting.
In response, New Line stated that their rights to a film of "The Hobbit" were time-limited, and since Jackson would not work with them again until the suit was settled, he would not be asked to direct "The Hobbit", as had been anticipated.
Fifteen actors are suing New Line Cinema, claiming that they have never received their 5% of revenue from merchandise sold in relation to the movie, which contains their likeness.
Similarly, the Tolkien estate sued New Line, claiming that their contract entitled them to 7.5% of the gross receipts of the $6 billion hit.
Overall according to New Line's accounts the trilogy made "horrendous losses" and no profit at all.
According to Lucasfilm, "" despite having earned $475 million at the box-office against a budget of $32.5 million, "has never gone into profit".
A WB receipt was leaked online, showing that the hugely successful movie "Harry Potter and the Order of the Phoenix" ended up with a $167 million loss on paper.
Michael Moore sued Bob and Harvey Weinstein for creative accounting to deprive him of his share of profits for the film "Fahrenheit 9/11".
Eventually, Moore reached a settlement with the Weinsteins and the lawsuit was dropped.
Actress Lynda Carter was also upset with some of the marketing of her image that involved Hollywood accounting.
Warner Bros. worked out a deal with the toy company Mego to create a Wonder Woman doll while the series was still on the air.
In 1987, on "The Late Show with Joan Rivers", Carter commented:I think that you're probably familiar with a problem in Hollywood, and that is that they market you, and they use you.
They did a mask of my face and put it on the doll, and they put my name on for the first run of it.
And then they took my name off and said they didn't have to pay me anymore.
So it's the kind of thing that you can be used so much in this industry.
I make nothing.
I don't even make anything from the reruns.
Don't ever settle for net profits.
It's called creative accounting. 
Hollywood accounting can take several forms.
In one form, a subsidiary is formed to perform a given activity and the parent entity will extract money out of the subsidiary not in terms of profits but in the form of charges for certain "services".
The specific schemes can range from the simple and obvious to the extremely complex.
Three main factors in Hollywood accounting reduce the reported profit of a movie, and all have to do with the calculation of overhead:  Production overhead: Studios, on average, calculate production overhead by using a figure around 15% of total production costs.
Distribution overhead: Film distributors typically keep 30% of what they receive from movie theaters ("gross rentals").
Marketing overhead: To determine this number, studios usually choose about 10% of all advertising costs.
All of the above means of calculating overhead are highly controversial, even within the accounting profession.
Namely, these percentages are assigned without much regard to how, in reality, these estimates relate to actual overhead costs.
In short, this method does not, by any rational standard, attempt to adequately trace overhead costs.
Due to Hollywood accounting, it has been estimated that only about 5% of movies officially show a net profit, and the "losers" include such blockbuster films as "Rain Man", "Forrest Gump", "Who Framed Roger Rabbit", and "Batman", which all took in huge amounts in box office and video sales.
Because of this, net points (a percentage of the net income (i.e.
gross income minus expenses), as opposed to a percentage of the gross income) are sometimes referred to as "monkey points", a term attributed to Eddie Murphy, who is said to have also stated that only a fool would accept net points in his or her contract.
All of this shows why so many big-name actors insist on "gross points" (a percentage of some definition of gross revenue) rather than net profit participation.
This practice reduces the likelihood of a project showing a profit, as a production company will claim a portion of the reported box-office revenue was diverted directly to gross point participants.
