NEW YORK (CNNMoney.com) - Howard Stern and his agent plan on cashing in some of their Sirius stock, the satellite radio broadcaster said Wednesday.

The satellite radio provider disclosed in a filing that Stern and his agent, Don Buchwald, told the company they were selling company shares, which were granted when Stern signing with Sirius, though it did not say how many.

As part of the deal, Stern was granted 31,250,000 shares, which have a current market value of just under $200 million. Buchwald was granted 3,125,000 shares currently valued at about $20 million.

Buchwald was not immediately available for comment.

Stern inked a five-year deal reportedly worth $500 million with Sirius (Research) in late 2004 while he was still under fire from regulators for his shows for previous employers.

But fans who expected a non-stop barrage of four-letter words and extensive scatological descriptions during Stern's first show on Sirius might have found the show relatively tame. (Full story.)
