It's not completely uncommon. It happens when a company with a strong brand and a diverse set of products hits a rough financial period, and the stockholders would benefit from a divestiture of one or more business lines. Typically the spun-off businesses are granted royalty free license to use the trademark of the parent in perpetuity. That grant makes the spun-off business more valuable, and more attractive to a buyer. If Honda were selling off their motorcycle business, and you were a potential buyer, would you rather be able to use the Honda name or not? Would you expect to pay more to become the maker of Honda branded motorcycles? The reason I know this: I once worked at Purina Mills - a company making commercial animal feeds, using the Purina name and the checkerboard logo, but completely separate from the Ralston Purina company that makes and markets Purina Dog Chow and Cat Chow. Purina Mills was spun off when the shareholders of Purina decided they wanted to be invested in the pet food business at the exclusion of their farm, zoo, and custom milling business.
