The publisher of Playboy magazine said Monday it has agreed to a sweetened offer by founder Hugh Hefner to take the company private.

The price of $6.15 a share is an 18 percent premium over Friday's closing price and values the company at about $207 million. The bid tops the Hefner-controlled Icon Acquisition Holdings LP's offer of $5.50 per share in July.

Playboy stock climbed 88 cents, or 16.9 percent, to $6.08 in morning trading.

A group led by Penthouse magazine has also made an offer for Playboy Enterprises Inc. valued at $210 million.

But Hefner is Playboy's largest shareholder with about 70 percent of the company's voting shares and 28 percent of the nonvoting stock.

The company's namesake magazine has struggled with competition from the Web, losing readers and advertisers. In November the company reported a wider third quarter loss than a year ago as its revenue fell 7 percent to $52.1 million.

Playboy's management has been trying to transform the company from a publishing and TV business into a "brand management" company, leaning more on revenue from licensing out the Playboy name and bunny ears for a range of products.

A group of board members had been evaluating Hefner's offer and decided to recommend the deal to stockholders Sunday night.

"I believe this agreement will give us the resources and flexibility to return Playboy to its unique position and to further expand our business around the world," Hefner said.

CEO Scott Flanders will remain in that position. A tender offer is expected to begin by Jan. 21 and the deal is expected to close by the end of the first quarter.
