perhaps something else comes with the bond so it is a convertible security. buffett's negative-interest issues sell well from 2002 would be an example from more than a decade ago: warren e. buffett's new negative-interest bonds sold rapidly   yesterday, even after the size of the offering was increased to $400   million from $250 million, with a possible offering of another $100   million to cover overallotments. the new berkshire hathaway securities, which were underwritten by   goldman, sachs at the suggestion of mr. buffett, berkshire's chairman   and chief executive, pay 3 percent annual interest. but they are   coupled with five-year warrants to buy berkshire stock at $89,585, a   15 percent premium to berkshire's stock price tuesday of $77,900. to   maintain the warrant, an investor is required to pay 3.75 percent each   year. that provides a net negative rate of 0.75 percent.
