A man who impersonated his successful father in a bid to buy Maxim magazine was sentenced Monday to only a year in prison because he cooperated with authorities.

Manhattan federal Judge Jed Rakoff sentenced Calvin Darden Jr., saying he “has spent too much of his life engaged in fraud or other wrongdoing.”

Rakoff said he might have required Darden to spend as much as five years in prison were it not for his substantial cooperation.

Authorities say the Staten Island man tricked two lenders in late 2013 into providing more than $8 million in financing for the potential acquisition of Maxim and tried to defraud another victim of $20 million.

In November 2014, Darden pleaded guilty after authorities said he impersonated his father, a former senior VP at Atlanta-based United Parcel Service, in his bid to buy the men’s lifestyle magazine.
